## Background
BACKGROUND
1. Technical Field
The present disclosure relates to bonding devices, and particularly to an automatic bonding device.
2. Description of Related Art

The suction member 77 is mounted to the sliding portion 753 of the lead screw 75.
In use, a plurality of first workpiece 200 are stacked and received in the feeding grooves 331. The first driver 38 drives the positioning plate 35 to move until the matching groove 353 is aligned to the feeding groove 331. The bottom one of the stacked plurality of first workpieces 200 is gravity-dropped to the matching groove 353 from the feeding groove 331. The first driver 38 drives the positioning plate 35 to move until the second positioning end 363 of the second positioning member 36 and the third positioning end 373 of the third positioning member 37 are received in the positioning groove 351. The second driving body 361 moves the second positioning end 363 along the direction Y, to position the first workpiece 200 received in the matching groove 353 in the direction Y. The third driving body 371 moves the third positioning end 373 along the direction X, to position the first workpiece 200 received in the matching groove 353 in the direction X. At the same time, the second workpiece 300 is conveyed on the transmission belt 13 until being blocked by the resisting block 19. Then, the telescopic driver 131 moves the fixing frame 14 vertically along the guiding member 15, and the positioning tool 16 receives and pushes the second workpiece 300, thereby detaching the second workpiece 300 from the transmission belt 13. The pressing members 18 press the second workpiece 300, to position the second workpiece 300 in the direction Z.

Then, the suction member 77 absorbs or suctioningly holds the first workpiece 200 received in the matching groove 353. The second driver 73 rotates the guiding portion 751 of the lead screw 75, such that the suction member 77 and the sliding portion 753 move along the guiding portion 751 until the first workpiece 200 reaches the glue spraying mechanism 50. The glue spraying mechanism 50 sprays glue to the first workpiece 200, and the second driver 73 continues to move the suction member 77 until reaching the second workpiece 300. The suction member 77 bonds the first workpiece 200 to the second workpiece 300. When the suction member 77 absorbs the first workpiece 200, another first workpiece 200 is fed simultaneously. When the first workpieces 200 that are received in one feeding groove 331 are used up, the horizontal driving member 32 moves the feeding member 33 until another feeding groove 331 aligns to the matching groove 353, which is convenient for supplying the first workpieces 200 in a timely manner.
The first workpiece 200 and the second workpiece 300 are fed automatically, and the second driver 73 drives the suction member 77 to move from the positioning plate 35 to the transmission belt 13, and to breaking to a stop when the suction member 77 reaches the glue spraying mechanism 50, and the first workpiece 200 are automatically bonded with the second workpiece 300, thus thereby saving a large amount of human labor and time. A bonding cost of the workpieces together is low. Because the first workpiece 200 automatically bonds with the second workpiece 300. a bonding accuracy is improved.
In an alternative embodiment, the lead screw 75 can be omitted, and then the suction member 77 are directly connected to the second driver 73, and the second driver 73 can be a cylinder which linearly moves the suction member 77. When more than one first workpiece 200 needs to be bonded to the second workpiece 300, more than one second feeding mechanism 30, more than one glue spraying mechanism 50, and more than one bonding mechanism 70 may be positioned around the first feeding mechanism 10, thus simultaneously bonding more than one first workpiece 200 to the second workpiece 300.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
