[0035] Please refer to Figures 1 to 9 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a mobile phone mid-plate welding device.

[0036] Among them, the mobile phone mid-plate welding equipment can realize feeding, positioning assembly, welding and unloading, and its functions are more complete and its degree of automation is higher.

[0037] This application provides a mobile phone mid-plate welding device, including a material preparation mechanism 20; a frame 11 and a plate 12 are placed on the material preparation mechanism 20; a welding positioning mechanism 50 is disposed beside the material preparation mechanism 20; a transfer mechanism 30 is disposed above the welding positioning mechanism 50; the transfer mechanism 30 can assemble the frame 11 and the plate 12 on the welding positioning mechanism 50; a welding mechanism 60 is disposed beside the welding positioning mechanism 50; the welding mechanism 60 can weld the frame 11 and the plate 12 together on the welding positioning mechanism 50; a recycling mechanism 65 is disposed beside the welding positioning mechanism 50; the transfer mechanism 30 transfers the mobile phone mid-plate 10 to the recycling mechanism 65. Production steps: 1. During production, a large number of frames 11 and plates 12 are placed into the material preparation mechanism 20, which continuously lifts the plates 12 and frames 11. 2. The transfer mechanism 30 picks up the plates 12 and frames 11 from the material preparation mechanism 20, and then places the plates 12 and frames 11 into the assembly pre-positioning mechanism 40 for pre-positioning. 3. After positioning, the plate 12 and frame 11 are successively placed into the welding positioning mechanism 50 to complete assembly. Then, the welding positioning mechanism 50 presses the plate 12 and frame 11 together; subsequently, the welding mechanism 60 welds the plate 12 and frame 11 together, ensuring a strong weld and preventing any weak welds. 4. The plate 12 and frame 11 are welded together to form the mobile phone mid-plate 10. The transfer mechanism 30 then transfers the mobile phone mid-plate 10 to the recycling mechanism 65 for recycling. It is evident that the mobile phone mid-plate welding equipment in this application achieves more complete functions in feeding, assembly, welding positioning, welding, and unloading, with a higher degree of automation.

[0038] Preferably, the material preparation mechanism 20 includes a first turntable 21, a first hopper 22 and a second hopper 23 disposed on the first turntable 21, and a lifting module 24 disposed on the lower side of the first turntable 21. A plate 12 is placed in the first hopper 22; a frame 11 is placed in the second hopper; and a bracket 25 on the lifting module 24 can lift the plate 12 and the frame 11. The first turntable 21 is driven to rotate by a cam divider and a speed-regulating motor. The lifting module 24 can be a lead screw servo module or a cylinder module. There are two sets of lifting modules 24: the bracket 25 of the first set lifts the plate 12; the bracket 25 of the second set lifts the frame 11. When the lifting module 24 operates, the bracket 25 can move up and down, thereby allowing the plate 12 and the frame 11 to move up and down. The first hopper 22 and the second hopper 23 are formed by uprights. This design makes it easy to observe the material condition, facilitates inspection, and prevents material jamming.

[0039] Preferably, the welding positioning mechanism 50 includes a second turntable 510, a lower mold 512 disposed on the second turntable 510, and an upper mold 530 that can close with the lower mold 512. The second turntable 510 is driven to rotate by a cam divider and a speed-regulating motor. The plate 12 and the frame 11 are placed into the lower mold 512 one after the other, and then the upper mold 530 and the lower mold 512 are closed, exposing the welding position at the welding machine hole, and the laser welds the welding position.

The upper mold core 536 and the lower mold core 514 are contoured, which can effectively position the mobile phone middle plate 10. Both the upper template 532 and the upper mold frame 531 are provided with rectangular clearance holes, which expose the welding holes 534. Laser head 63 welds the mobile phone middle plate 10 at welding hole 534.

The positioning block 515 can position the upper and lower ends of the mobile phone middle plate 10, and the positioning post 516 passes through the frame 11 and the plate body 12 to ensure that there is no displacement, which helps to ensure the quality of welding.

The top plate 541 on the output end of the first cylinder 540 can drive the ejector pins 537 to eject the mobile phone middle plate 10 on the lower mold core 514. The first spring enables the ejector pins 537 to return to their original position. The position of the protrusions 542 can be set as needed. The protrusions 542 can allow the mobile phone middle plate 10 to be ejected as a whole at the same time, for example, the frame 11 and the plate 12 can be ejected at the same time. This design can prevent deformation. At the same time, the protrusions 542 can also make the rubber head of each ejector pin 537 fit with the contour height of the mobile phone middle plate 10 when the ejector pins 537 are lifted.

The plate 12 is placed into the first positioning fixture 46 for positioning, and the frame 11 is placed into the second positioning fixture 47 for positioning. The plate 12 and the frame 11 are assembled on the welding positioning mechanism 50. The second linear module 31 is a lead screw servo module, which can accurately drive the loading suction cup module 33 and the unloading suction cup module 35 to move laterally. The first lead screw servo module 32 drives the loading suction cup module 33 to move up and down, and the second lead screw servo module 34 drives the unloading suction cup module 35 to move up and down. Both the loading suction cup module 33 and the unloading suction cup module 35 are equipped with suction cups, which can be used to pick up the plate 12 and the frame 11. In this embodiment, there are two sets of feeding suction cup modules 33, which can respectively position the plate 12 and the frame 11, facilitating the subsequent assembly of the plate 12 and the frame 11 in the lower mold 512. One of the feeding suction cup modules has a clamp that can hold the frame. The clamp and the suction cup work together to firmly fix the frame and prevent it from loosening. This design solves the problem of insufficient suction area for the frame 11, ensuring a high success rate of feeding. The plate is then transferred using the suction cup.
