Furthermore, the fixing device cannot automatically clamp and fix mobile phone back covers of various sizes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention uses a drive mechanism to drive the first transfer mechanism, the clamping mechanism, and the second transfer mechanism to achieve the effect of automatically transporting the phone back cover to the clamping mechanism and automatically clamping and fixing the phone back cover, as well as the function of automatically transporting the processed phone back cover away.

The rotation of the first rotating shaft drives the first, second, and third swing arms to swing. In conjunction with the material handling device, the back cover of the mobile phone at the discharge assembly is automatically transported to the top of the clamping mechanism. The rotation of the second rotating shaft drives the movement of the clamping plate, enabling the clamping plate to automatically clamp, fix, and release the back cover of the mobile phone.

[0054] Working principle: In use, the back cover of the mobile phone is transported through the feeding assembly 3. The motor 108 drives the drive shaft 103 to rotate. The rotation of the drive shaft 103 drives the first sector gear 109 and the notched disc 110 on it to rotate. The first gear 111 can mesh with the first sector gear 109, and the outer wall of the chuck 112 can engage with the outer ring of the notched disc 110, so that the drive shaft 103 can drive the three transmission shafts 104 to rotate intermittently. The three transmission shafts 104 are respectively connected to the first rotating shaft 105, the second rotating shaft 106 and the third rotating shaft 107 through transmission belts and pulleys, so that the rotation of the three transmission shafts 104 can drive the first rotating shaft 105, the second rotating shaft 106 and the third rotating shaft 107 to rotate respectively.

[0055] The rotation of the first rotating shaft 105 drives the rotating arm 506 to rotate, the rotation of the rotating arm 506 drives the second connecting column 505 to rotate in a circle, the rotation of the second connecting column 505 drives the second swing arm 504 to swing, and the first swing arm 502 connected to the other end of the second swing arm 504 through the first connecting column 503 swings around the first fixed shaft 501. The moving rod 507 at the top of the swing of the first swing arm 502 swings. When the moving rod 507 swings, it can drive the third swing arm 510 connected to it through the fixed seat 509 to swing around the second fixed shaft 512. When the third swing arm 510 swings, it can slide inside the limiting column 511. When the moving rod 507 swings to the top of the clamping mechanism 6, the picking device 8 connected to the moving rod 507 through the connecting seat 508 can be located above the clamping mechanism 6. Thus, the picking device 8, under the transfer of the first transfer mechanism 5, transports the back cover of the mobile phone from the feeding component 3 to the top of the clamping mechanism 6.

[0056] The rotation of the second rotating shaft 106 drives the second sector gear 113 to rotate. The rotation of the second sector gear 113 drives the first moving gear ring 602 to reciprocate on the limiting bracket 601. The reciprocating movement of the first moving gear ring 602 drives the concave seat 603 and the rack 604 to reciprocate. The reciprocating movement of the rack 604 drives the third gear 608 to reciprocate. The rotation of the third gear 608 drives the first rotating rod 606 and the second gear 607 thereon to reciprocate. The reciprocating movement of the second gear 607 drives the second moving gear ring 609 to reciprocate. The reciprocating movement of the second moving gear ring 609 drives the threaded cylinder 611 on the slide rail 610 and the clamping plate 614 connected to the threaded cylinder 611 to reciprocate. When the second rotating shaft 106 rotates in one direction, the clamping plate 614 can clamp and fix the back cover of the mobile phone. Then the back cover of the mobile phone can be processed. After the processing is completed, when the second rotating shaft 106 rotates in the opposite direction, the clamping plate 614 releases the clamping and fixing of the back cover of the mobile phone.

[0057] By rotating the second rotating rod 615, the threaded sleeve 617 is no longer in contact with the bottom end of the slide rail 610, thereby allowing the threaded cylinder 611 to move, making it convenient to adjust the position of the clamping plate 614, so that the clamping mechanism 6 can clamp and fix mobile phone back covers of various sizes.

[0058] The rotation of the third rotating shaft 107 drives the turntable 701 to rotate, which in turn drives the cylinder 702 to rotate in a circular motion. The rotation of the cylinder 702 drives the moving ring 706 to reciprocate up and down, which in turn drives the connecting arm 707 connected to the slide plate 705 to reciprocate up and down. This allows the connecting arm 707 to remove the processed mobile phone back cover from the clamping mechanism 6 via the material handling device 8. When the connecting arm 707 descends, it drives the two fourth swing arms 709 to deflect around the fixed pin 714 and the hinge seat 715 respectively. The first connecting rod 710 on the two fourth swing arms 709 follows the movement of the first connecting rod 710. The second discharge channel 708 slides on the fourth swing arm 709, and the fifth swing arm 712, which is rotatably connected to the other end of the fourth swing arm 709, deflects around the third connecting rod 713, so that the second discharge channel 708 can move away from above the clamping mechanism 6 during the descent of the connecting arm 707, so that the picking device 8 at the bottom of the connecting arm 707 can smoothly pick up the processed mobile phone back cover. When the connecting arm 707 rises, the second discharge channel 708 moves to the lower position of the picking device 8 connected to the connecting arm 707, so that the mobile phone back cover on the picking device 8 can fall into the second discharge channel 708.

[0059] When the second discharge channel 708 moves, it is rotatably connected to the second connecting channel 404 via a connecting pin 405 and a fixing rod 406, allowing the second discharge channel 708 and the second connecting channel 404 to deflect. The first discharge channel 402 and the first connecting channel 403 are rotatably connected via a connecting pin 405 and a fixing rod 406, allowing the first discharge channel 402 and the first connecting channel 403 to deflect. The first connecting channel 403 and the second connecting channel 404 are interlocked, allowing the length of the transport channel formed by the first connecting channel 403 and the second connecting channel 404 to be adjusted. Thus, the second discharge channel 708 can move smoothly, and after moving, the back cover of the mobile phone can be transported away using the transport channel formed by the first connecting channel 403 and the second connecting channel 404 and the first discharge channel 402.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
