In modern society, mobile phones have gradually become an indispensable tool for people. As part of the appearance of mobile phones, the design and material of the back shell of mobile phones reflect the design concept and style of the mobile phone brand. By polishing the back shell of mobile phones, the surface roughness can be reduced, thereby reducing the possibility of friction and wear. The polished surface is less likely to accumulate dust and dirt, and is easier to clean and maintain. At the same time, it improves the overall texture and grade of the product, helps the brand to create a high-end image, and makes consumers more fond of and trust the product.

[0003] In the prior art, when polishing the back shell of a mobile phone, a robotic arm is used to take the back shell of the mobile phone out of a material collection box, place it on a mold, and then use the robotic arm to perform a multi-sided polishing process on it.

Moreover, during the multi-sided polishing process, manual adjustment and intervention of the robotic arm are often required to ensure the consistency and quality of the polishing effect, which increases labor costs.

The steering motors on both sides operate simultaneously to drive the variable pitch screws to rotate in the same direction. When the T-shaped mold enters between the two variable pitch screws, the elliptical cylinder at the bottom of the T-shaped mold rotates 90 degrees under the action of the spiral groove of the variable pitch screw. The T-shaped mold moves out of the variable pitch screw at a 90-degree posture and enters the longitudinal polishing assembly to polish the short side of the mobile phone back shell. This can reduce manual intervention, reduce manual operation costs, improve production efficiency, and also reduce the possibility of human errors. At the same time, the polishing equipment can achieve polishing in another direction without changing the operating speed, thereby increasing the polishing output in each cycle and improving production efficiency.

The correction frame 614 can ensure that the mold is in the correct posture before entering the first polishing plate 612, so that the polishing process can be more uniform. In order to avoid uneven or incomplete polishing caused by incorrect posture, thereby improving the appearance quality and surface finish of the final product, two fixed seats 613 are installed at the center of the bottom of the U-shaped mounting frame 61, and the tops of the two fixed seats 613 are rotatably connected with double-linked threaded rods 63, which can complete multi-faceted polishing processing and reduce the demand for multiple single-function equipment, thereby saving the space layout of the production workshop and improving space utilization. The two ends of the double-linked threaded rod 63 are rotatably connected to the U-shaped mounting frame 61, and a first limiting bar 64 is arranged between the fixed seat 613 and the U-shaped mounting frame 61. The first limiting bar 64 is fixedly connected to the U-shaped mounting frame 61, and the top of the first limiting bar 64 is slidably connected to a first slider 65, and the first slider 65 is rotatably connected to connecting blocks 66 on both sides. , the connecting block 66 is slidably connected to an H-shaped rotating frame 67, the top of the H-shaped rotating frame 67 is rotatably connected to a support frame 62, the bottom end of the support frame 62 is fixedly connected to the U-shaped mounting frame 61, and levers 618 are installed on both sides of the top of the H-shaped rotating frame 67. The support frame 62 and the U-shaped mounting frame 61 are slidably connected with a sliding rod 68, and the sliding rod 68 is slidably connected with the synchronous wheel of the first synchronous belt 610. By completing multi-faceted polishing at one time, the transportation process of the product between different equipment can be reduced, and the risk of product damage caused by transportation can be reduced, thereby improving the yield rate. A plurality of second limiting strips 69 are welded on the outer wall of the side of the sliding rod 68 away from the H-shaped rotating frame 67.

The connecting block 66 is located in the slide groove of the H-shaped rotating frame 67.

[0036] The working principle of this embodiment is as follows: the staff starts the electromechanical equipment inside the dust cover 2 by operating the controller 4, and then the transmission motor 5 drives the sprocket 91 to rotate so that the chain 92 is transmitted, so that the second slider 94 moves in a circle on the annular slide rail 93. The staff can stand on one side of the support platform 1 and put the back shell of the mobile phone into the top of the T-shaped mold 95 one by one for engagement. When the second slider 94 passes the arc end of the annular slide rail 93, under the action of centrifugal force, the T-shaped mold 95 will deflect with the second slider 94, and when the staff is loading, the T-shaped mold 95 will deflect with the second slider 94. Therefore, when the T-shaped mold 95 moves between the two correction frames 614, due to the elliptical structure of the bottom of the T-shaped mold 95, the correction frame 614 and the T-shaped mold 95 slide relative to each other, and the correction frame 614 shrinks, so that the long end of the elliptical column at the bottom of the T-shaped mold 95 moves into the transverse polishing component 6; Before the T-shaped mold 95 enters the transverse polishing assembly 6, the second motor 616 in the transverse polishing assembly 6 and the longitudinal polishing assembly 10 runs simultaneously to drive the second synchronous belt 611 to transmit, so that the first synchronous belt 610 follows the synchronous transmission, and under the action of the second limit bar 69, the slide bar 68 rotates, and the first polishing discs 612 on both sides follow the synchronous rotation, and then the second motor 616 in the transverse polishing assembly 6 rotates, thereby rotating the double-threaded rod 63, so that the two first sliders 65 are linearly aligned along the first limit bar 64. When the connecting block 66 moves forward or backward, the connecting block 66 moves synchronously with it. Since the connecting block 66 is in the slide groove of the H-shaped rotating frame 67, the connecting block 66 rotates while moving, and the connecting block 66 slides in the slide groove of the H-shaped rotating frame 67, thereby causing the H-shaped rotating frame 67 to rotate. Under the action of the lever 618, the fixed plate 617 is driven to move horizontally to adapt to the long side of the mobile phone rear shell at the top of the T-shaped mold 95, and then the T-shaped mold 95 is polished on its long side by the first polishing plate 612 in the horizontal polishing assembly 6; After the long side of the mobile phone back shell is polished, the T-shaped mold 95 enters the steering assembly 7, and the steering motors 73 on both sides operate simultaneously to drive the variable pitch screw 72 to rotate, and the rotation directions are consistent. When the T-shaped mold 95 enters between the two variable pitch screws 72, the elliptical cylinder at the bottom of the T-shaped mold 95 is acted on by the spiral groove of the variable pitch screw 72, and the T-shaped mold 95 rotates 90 degrees during the movement, and moves out of the variable pitch screw 72 with its 90-degree posture. When the T-shaped mold 95 rotates in the chain 92, the mobile phone back shell at the top of the T-shaped mold 95 passes through the second polishing disc 83, and the polishing motor 82 operates to rotate the second polishing disc 83 to polish its back; After polishing the back and long sides of the mobile phone rear shell, when the T-shaped mold 95 moves to the center of the first polishing disc 612 in the longitudinal polishing assembly 10, the second motor 616 in the longitudinal polishing assembly 10 drives the second synchronous belt 611 to transmit, so that the first synchronous belt 610 follows the synchronous transmission, and under the action of the second limit bar 69, the slide bar 68 rotates, and the first polishing discs 612 on both sides follow the synchronous rotation, and then the second motor 616 in the transverse polishing assembly 6 rotates, thereby rotating the double-linked threaded rod 63, so that the two first sliders 65 move in opposite directions along the linear direction of the first limit bar 64, so that the first polishing disc 612 polishes the short side of the mobile phone rear shell on the T-shaped mold 95. After polishing, the longitudinal polishing assembly 10 runs in the reverse direction to make the two slide bars 68 move in the reverse direction. After polishing of the mobile phone rear shell is completed, the T-shaped mold 95 moves to the other end of the annular slide rail 93, and the staff can take out the polished mobile phone rear shell.
