The present invention is directed to an ink cartridge for enhancing the production yield.
The following embodiments are illustrated with reference to the accompanied drawings, so as to illustrate the specific embodiments for implementing the present invention. The direction terms mentioned in the present invention such as “up”, “down”, “front”, “back”, “left” and “right” only refer to the directions in the accompanied drawings. Therefore, the direction terms are used for illustrating and not for limiting the present invention.
The body 210 has three ink chambers 212 a to 212 c and three ink delivery ports 216 a to 216 c. The ink delivery ports 216 a to 216 c are respectively located at a bottom 250 of the body 210, and the ink chambers 212 a to 212 c respectively fluidly communicate with the ink delivery ports 216 a to 216 c.
The channel module 220 has a chip bonding area R, three flow channels 222 a to 222 c, and three ink supply ports 224 a to 224 c. The ink supply ports 224 a to 224 c are located in the chip bonding area R, and the flow channels 222 a to 222 c respectively fluidly communicate ink delivery ports 216 a to 216 c with the ink supply ports 224 a to 224 c.
The engaging parts 230 a to 230 d are arranged on the body 210, for example, in the form of the four blocks or protrusions (the blocks and protrusions referred to as blocks in the present invention), and the engaging parts 240 a to 240 d are arranged on the channel module 220, for example, in the form of the four indentations or grooves or notches (the indentations or grooves or notches referred to as “indentations” in the present invention) as shown in FIG. 2A. The relative position of the body 210 and the channel module 220 on a two-dimension plane on the surface of the bottom 250 is substantially fixed by the engagement of the engaging parts 230 a to 230 d and the engaging parts 240 a to 240 d. The two-dimension plane is a plane extended along the x-axis and y-axis in FIGS. 2A and 2B. It should be noted that the term “fixed” in the description of “the relative position of the body and the channel module on a two-dimension plane on the surface of the bottom is substantially fixed” or the like in the embodiments of the present invention includes the meaning of locating the relative position between the channel module and the body.
Compared with the blocks 118 a and 118 b of the conventional ink cartridge 100 and the corresponding indentations 128 a and 128 b which can only restrict the channel module 120 from moving along the positive x-axis, negative x-axis, and negative y-axis relatively to the body 110, the engaging parts 230 a to 230 d and the engaging parts 240 a to 240 d of the first embodiment can restrict the channel module 220 from moving along the positive x-axis, negative x-axis, positive y-axis, and negative y-axis relatively to the body 210, and can also restrict the channel module 220 from rotating about the z-axis (orthogonal to the x-axis and y-axis) relatively to the body 210. In other words, not only a deviation of the channel module 220in x-axis and y-axis directions but also the rotation deviation about the z-axis (orthogonal to the x-axis and y-axis) can be prevented, when the channel module 220 is assembled on the body 210, by the engagement or cooperation of the engaging parts 230 a to 230 d and the engaging parts 240 a to 240 d.
Since the engaging parts 230 a to 230 d and the engaging parts 240 a to 240 d are used for locating the relative position between the channel module 220 and the body 210, the accuracy of orientation of the channel module 220 with respect to the body 210 can be improved. Therefore, when the channel module 220 is attached to the body 210, for example, by means of ultrasonic welding, the welding quality and yield can be enhanced because of the engagement of the engaging parts 230 a to 230 d and the engaging parts 240 a to 240 d. However, the method of fixing the channel module 220 onto the body 210 in the present embodiment is not limited to the ultrasonic welding, other methods such as laser welding, or bonding by adhesive can also be used to fix the channel module 220 onto the body 210. The arrangement of engaging parts in the present invention can assist to locate the channel module 220 onto the body 210. Moreover, by respectively measuring the distance between the engaging parts 230 a to 230 d and the distance between the engaging parts 240 a to 240 d, the inspector or manufacturer can easily inspect whether the channel module 220 or body 210 is manufactured within an allowable tolerance before fixing the channel module 220 onto the body 210, thereby ensuring that the channel module 220 can be correctly fitted and located on the body 210.
The body 310 has three ink chambers 312 a to 312 c and three ink delivery ports 316 a to 316 c. The ink delivery ports 316 a to 316 c are located at a bottom 350 of the body 310, and the ink chambers 312 a to 312 c respectively fluidly communicate with the ink delivery ports 316 a to 316 c.
The channel module 320 is attached to the bottom 350 of the body 310. The channel module 320 has a chip bonding area R, three flow channels 322 a to 322 c, and three ink supply ports 324 a to 324 c. The ink supply ports 324 a to 324 c are located in the chip bonding area R, and the flow channels 322 a to 322 c respectively fluidly communicate ink delivery ports 316 a to 316 c with the ink supply ports 324 a to 324 c.
The channel module 320 has a base 320 a attached to the body 310, an uplift portion 320 b protruding from the base 320 a. The chip bonding area R is formed on the uplift portion 320 b. The base 320 a has a base surface B. The uplift portion 320 b has a side surface S connecting the base surface B and the chip bonding area R, and the angle A between the side surface S and the base surface B is between 90 degrees and 135 degrees.
The body 410 has three ink chambers 412 a to 412 c and three ink delivery ports 416 a to 416 c. The ink delivery ports 416 a to 416 c are respectively located at a bottom 450 of the body 410, and the ink chambers 412 a to 412 c respectively fluidly communicate with the ink delivery ports 416 a to 416 c.
The channel module 420 includes a chip bonding area R, three flow channels 422 a to 422 c, and three ink supply ports 424 a to 424 c. The ink supply ports 424 a to 424 c are located in the chip bonding area R, and the flow channels 422 a to 422 c respectively fluidly communicate ink delivery ports 416 a to 416 c with the ink supply ports 424 a to 424 c.
The channel module 420 further has a base 420 a attached to the body 410 and an uplift portion 420 b protruding from the base 420 a. The chip bonding area R is formed on the uplift portion 420 b. The base 420 a has a base surface B. The uplift portion 420 b has a side surface S connecting the base surface B and the chip bonding area R, and the angle A between the side surface S and the base surface B is between 90 degrees and 135 degrees.
The engaging parts 430 a to 430 d may be arranged on the body 410 in the form of four blocks as shown in FIG. 4A, and the engaging parts 440 a to 440 d may be arranged on the channel module 420 in the form of four indentations as shown in FIG. 4A. The relative position of the body 410 and the channel module 420 on a two-dimension plane is substantially fixed by the engagement of the engaging parts 430 a to 430 d and the engaging parts 440 a to 440 d. The two-dimension plane is a plane extended along the x-axis and y-axis in FIGS. 2A and 2B. By the engagement of the engaging parts 430 a to 430 d and the engaging parts 440 a to 440 d, the movement of the channel module 420 along the positive x-axis, negative x-axis, positive x-axis, and negative y-axis relatively to the body 410 can be restricted, and the rotation of the channel module 420 about the z-axis (orthogonal to the x-axis and y-axis) relatively to the body 410 can also be restricted. In other words, not only a deviation of the channel module 420 in x-axis and y-axis directions but also the rotation deviation about the z-axis (orthogonal to the x-axis and y-axis) can be prevented, when the channel module 420 is assembled onto the body 410 by the engagement or cooperation of engaging parts 430 a to 430 d and the engaging parts 440 a to 440 d.
In one embodiment, the engaging parts 430 a to 430 d are respectively arranged at the four corners on the surface of the bottom 450, as shown in FIG. 4A. The engaging parts 430 a to 430 d when arranged at two corners on the bottom 450 can provide protection for the channel module 420 fixed on the bottom 450, such that the damage to the channel module 420 or separation of the channel module 420 from the body 410, caused by the collision of the channel module 420 when the ink cartridge 400 falls onto the floor, can be avoided.
