These stations are driven by a drive device to form a complete working cycle, thereby realizing automatic transportation of products. They are composed of a material receiving platform, a diaphragm platform, a loading and unloading manipulator, a diaphragm manipulator and other parts, and each independently completes the patch work. The characteristics of the present invention are: compact structure, ingenious design, simultaneous operation of the machine heads, and the automation of the production process of medium-sized backlight sources is realized through PLC control technology.

[0050] By adopting the above technical solution, the rotation of the central shaft 504 can drive the four moving seats 510 to move simultaneously.

[0051] Working principle: When the present invention is in use, the mobile phone accessories and the backlight sheet are transported to the side of the material taking device 4 through the conveyor belt, and the motor 111 is used to drive the driving shaft 110 to rotate. The driving shaft 110 drives the first sector gear 112, the first notched disc 113, the second sector gear 114 and the second notched disc 115 thereon to rotate. The first sector gear 112 is able to engage with the first gear 116, and the outer ring of the first notched disc 113 is able to engage with the outer ring of the first chuck 117, so that the driving shaft 110 rotates to drive the first transmission shaft 108 to rotate intermittently. The second sector gear 114 is able to engage with the second gear 118, and the outer ring of the second notched disc 115 is able to engage with the outer ring of the second chuck 119, so that the driving shaft 110 can drive the second transmission shaft 109 to rotate intermittently.

[0052] The plurality of rotating shafts 304 and the second transmission shaft 109 are connected by transmission belts and pulleys, so that the rotation of the second transmission shaft 109 can drive the plurality of rotating shafts 304 to rotate, the rotation of the rotating shaft 304 drives the second turntable 305 to rotate, and the rotation of the second turntable 305 drives the cylinder 306 thereon to rotate in a circle. The movable ring 316 can slide along the moving direction of the movable rod 308, so that the rotation of the cylinder 306 drives the movable ring 316 to move back and forth, and the reciprocating movement of the movable ring 316 drives the connecting bracket 309 to move back and forth, and the connecting bracket The reciprocating movement of the rack 309 drives the rack 310 to move reciprocally, and the reciprocating movement of the rack 310 drives the third gear 312 to rotate reciprocally, and the first rotating column 311 at the center of the third gear 312 rotates reciprocally accordingly. The two first rotating columns 311 are connected by a synchronous belt and a synchronous wheel, so that the two first rotating columns 311 rotate simultaneously. The rotation of the first rotating columns 311 drives the rotating arm 313 to swing back and forth. The reciprocating swing of the rotating arm 313 drives the base 315 connected to its other end to swing back and forth, thereby transporting the accessories on the conveyor belt or the accessories that have finished patching.

[0053] The transfer mechanism 3 with a cylinder 306 at a different position from the other transfer mechanisms 3 works in the opposite direction to the remaining transfer mechanisms 3, and uses the material taking device 4 to transport the mobile phone accessories that have completed patching to the conveyor belt and transport them away. At this time, the remaining transfer mechanisms 3 use the material taking device 4 to transport the mobile phone accessories that have not been patched on the conveyor belt to between the four clamping plates 517 of the limiting mechanism 5 on one side thereof, or transport the backlight source to the mobile phone accessories that have not been patched for patching;

[0054] The first transmission shaft 108 rotates to drive the first turntable 107 to rotate, and the rotation of the first turntable 107 drives the plurality of limiting mechanisms 5 thereon to rotate in a circular manner. When the limiting mechanism 5 on which the un-patched mobile phone accessories are placed moves, the fourth gear 505 on the central shaft 504 can mesh with the plurality of gear teeth 106 on the inner ring of the outer ring 104, so that the fourth gear 505 can rotate during the movement, thereby driving the central shaft 504 to rotate, and the rotation of the central shaft 504 drives the third turntable 506 to rotate, and the third turntable 506 rotates. The movable swing arm 507 deflects, and the swing arm 507 deflects to drive the movable base 510 to move. The movement of the movable base 510 drives the clamping plate 517 connected to it via the threaded rod 514 to move, thereby clamping and limiting the mobile phone accessory that has not been patched. At this time, the fourth gear 505 on the central axis 504 of the limiting mechanism 5 where the mobile phone accessory with the patch is located can engage with the gear teeth 106 of the outer ring of the inner ring 105 during the movement process, causing the fourth gear 505 to rotate in the opposite direction, thereby releasing the clamping limit of the mobile phone accessory, which is convenient for the material removal device 4 to remove;

[0055] By rotating the threaded cylinder 513, the threaded rod 514 is allowed to move linearly under the limiting action of the guide rod 516. The movement of the threaded rod 514 drives the clamping plate 517 to move, thereby adjusting the position of the clamping plate 517, so that the four clamping plates 517 can clamp and limit mobile phone accessories of various sizes while moving a fixed distance.

[0056] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
