## Background
BACKGROUND
1. Technical Field
The present disclosure relates to transferring devices, and particularly, to a transferring device for conveniently reloading workpieces.
2. Description of Related Art
Conveyer belts may be used to automatically transfer workpieces from a previous process to another process. A workpiece may be put into a jig, and the jig carrying the workpiece is put onto the conveyer belt for transferring. However, when the workpiece on the conveyer belt needs to be replaced with another workpiece, the jig carrying the workpiece needs to be manually taken out from the conveyer belt first, and then put onto the conveyer belt again after reloading another workpiece. It is a waste of time for reloading a workpiece via aforementioned processes.
Therefore, there is room for improvement in the art.

The driving body 3331 is mounted on the mounting block 3313, and is perpendicular to the conveying member 133. The driving portion 3335 is slidably mounted on the driving body 3331. The driving body 3331 is capable of driving the driving portion 3335 to slide along the driving body 3331.
The third driving member 335 is mounted on the driving portion 3335. The driving body 3331 drives the third driving member 335 to move along a direction perpendicular to the conveying member 133 via the driving portion 3335. The pair of catches 337 are mounted on opposite sides of the third driving member 335, respectively. The third driving member 335 drives the pair of catches 337 to clamp or release the workpiece together with the jig 50. The catches 337 include a connecting body 3371, a pair of clamping portions 3373, and a pair of compressing portions 3375. A substantially middle portion of the connecting body 3371 is mounted on the third driving member 335, and the connecting body 3371 is substantially parallel to the positioning portions 1311. The pair of clamping portions 3373 are bent from opposite ends of the connecting body 3371 towards the other catch 337, respectively. The pair of compressing portions 3375 are substantially L-shaped, and are mounted on the clamping portions 3373, respectively. A gap 3376 (shown in FIG. 5) exists between a bottom surface 3377 of each compressing portion 3375 and the corresponding clamping portion 3373, for grasping and positioning the jig 50.
The jig 50 includes a bottom cover 51 and a top cover 53 engaged with the bottom cover 51. The bottom cover 51 and the top cover 53 define a receiving room 55 cooperatively, for receiving and positioning the workpiece. The bottom cover 51 is substantially rectangular, and defines a positioning portion 511 at a sidewall thereof away from the receiving room 55, to enable the jig 50 to be positioned and conveyed on the conveying member 133. The top cover 53 is substantially cubic, and a width of the top cover 53 is substantially equal to a width between the pair of clamping portions 3373. The top cover 53 forms four grasping portions 531 at four corners thereof, respectively. In the illustrated embodiment, the positioning portion 511 is a groove corresponding to the conveying member 133. The grasping portion 531 is a groove engaging with the corresponding clamping portion 3373.
In assembly, first, the mounting member 131 is mounted on the support posts 113, and the conveying member 133 is wound on the slave shafts 1313. Second, the positioning ends 3113 of the blocking assembly 31 is mounted on the positioning portions 1311, and the blocking assembly 31 is located below the positioning portions 1311. Third, the fixing member 331 is mounted on the positioning portions 1311, and the grasping assembly 33 is located above the positioning portions 1311 corresponding to the blocking assembly 31. Finally, the jig 50 is put on the conveying member 133 for conveying workpieces.
In use, a workpiece (not shown) is received in the receiving room 55 of the jig 50, and the jig 50 is transferred along the conveying member 133 towards the grasping assembly 33. The transferring device 100 is in a first state of use (shown in FIG. 3). When the jig 50 moves to a position below the catches 337, the driving body 3151 of the first driving member 315 drives the connecting portion 3155 to move towards the driving body 3151, thereby the engaging portion 3131 being driven to move towards the main body 3111 of the holding member 311. The blocking posts 3133 move towards the conveying member 133 along the through hole 3115, thus a distal end of each blocking post 3133 extends across the conveying member 133. The jig 50 is stopped by the blocking posts 3133. The third driving member 335 drives four clamping portions 3373 to grasp the grasping portions 531 of the top cover 53. The second driving member 333 drives the catches 337 and the top cover 53 to move away from the bottom cover 51, for conveniently reloading a new workpiece. The transferring device 100 is in a second state of use (shown in FIG. 4). After reloading a new workpiece manually or automatically, the second driving member 333 drives the catches 337 and the top cover 53 to move towards the bottom cover 51. The catches 337 release the new workpiece driven by the third driving member 335. The driving body 3151 drives the blocking posts 3133 to move away from the conveying member 133, so that the jig 50 is capable of moving along the conveying member 133 again.
In an alternative embodiment, the blocking posts 3133 may be mounted on a side of the positioning portion 1311 opposite to the support posts 113, and the blocking assembly 31 is located above the conveying member 133. The compressing portions 3375 and the grasping portions 531 may be omitted, and the clamping portions 3373 may clamp opposite sidewalls of the top cover 53.
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.
