[0002] With the rapid development of the electronic equipment industry, the appearance quality and performance requirements of electronic equipment are getting higher and higher. Especially in the processing of computer back panels, polishing is a key link, which directly affects the appearance and performance of electronic equipment.

[0003] When the existing device is performing a polishing operation on the computer back panel, the computer back panel is usually fixed first, and then the polishing device is controlled to reciprocate on the surface of the computer back panel to complete the polishing of the computer back panel.

Compared with other areas of the computer back panel, the polishing amount at both ends of the computer back panel will be significantly greater, which is easy to cause local over-polishing. In view of this, we propose a polishing device for electronic equipment processing. Summary of the invention

[0017] As a further improvement of the technical solution, the length of the limit box is smaller than the length of the connecting frame, and the internal size of the limit box is matched with the size of the computer back panel to be polished.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the polishing device used for processing electronic equipment, the sliding block and the connecting block are driven to slide inside the connecting frame by rotating the screw rod, and when the connecting block drives the connecting column and the connecting block to move synchronously through the moving block, the connecting column will contact the control switch in the guide groove provided in the connecting frame, so that the connecting block can reciprocate on the surface of the computer back panel. When the connecting column moves, the surface of the computer back panel of the polishing plate is driven to reciprocate through the mounting block, thereby polishing the computer back panel. At the same time, the mutual cooperation between the connecting column and the guide groove drives the polishing plate to reciprocate and move back and forth while moving left and right. The mutual cooperation between the connecting column and the guide groove enables the polishing plate to reciprocate and move back and forth while moving back and forth. This multi-directional movement can more comprehensively cover the surface of the computer back panel, ensuring that every corner can be fully polished.

[0020] 2. In the polishing device for processing electronic equipment, the cylinder is started by squeezing the control member during the movement of the connecting block, the first trapezoidal block and the second trapezoidal block are driven to contact each other through the moving block and the first trapezoidal block during the movement of the cylinder output shaft end, the first trapezoidal block and the second trapezoidal block are driven to slide to the side close to the polishing plate through the sliding plate during the contact between the inclined surfaces of the first trapezoidal block and the second trapezoidal block, the moving block drives the collecting box to contact the polishing sheet installed at the bottom of the polishing plate, after the contact, the planes of the first trapezoidal block and the second trapezoidal block fit together to avoid squeezing of the collecting box and the bottom of the polishing plate, and at the same time, the collecting box and the polishing plate slide synchronously to the side close to the cylinder, and the polishing plate is driven to reciprocate left and right through the cooperation of the guide groove opened at the bottom of the connecting frame and the connecting column, at this time, the bottom of the polishing plate contacts the cleaning sheet inside the collecting box, thereby cleaning the polishing sheet installed at the bottom of the polishing plate, the synchronous movement of the collecting box and the polishing plate and the contact cleaning with the polishing sheet make the cleaning process closely combined with the polishing operation, and the polishing sheet can be cleaned in time while the polishing plate reciprocates left and right, without affecting the continuity of polishing.

[0021] 3. In the polishing device for processing electronic equipment, when the first trapezoidal block and the second trapezoidal block are fitted at the inclined surface and the sliding plate drives the moving block to slide toward the side close to the polishing plate, the sliding plate synchronously drives the rack to move toward the direction close to the rotating column. When the planes of the first trapezoidal block and the second trapezoidal block are fitted, the rack is meshed with the rotating column. At this time, the sliding plate continues to move toward the direction close to the motor through the moving block, and the rack drives the gear to rotate through the rotating column at the same time. When the gear rotates, the limit box is driven to rotate through the rotating plate, so that the computer back panel inside the limit box is turned over, and the computer back panel away from the motor is polished;

[0022] When the connecting block moves away from the motor, the connecting column squeezes the connecting frame close to the second control switch installed in the bottom guide groove on one side of the motor, and the cylinder is closed. When the connecting column squeezes the connecting frame away from the first control switch installed in the bottom guide groove on one side of the motor, the output shaft end of the cylinder is started to slide toward the side away from the motor. At this time, the planes of the first trapezoidal block and the second trapezoidal block are fitted, and the rack is meshed with the rotating column. The rotating column will drive the computer back panel to rotate through the rotating plate and the limit box, thereby polishing the computer back panel close to the motor side to avoid excessive polishing at both ends of the computer back panel.

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] A polishing device for processing electronic equipment comprises a processing table 1, a polishing structure 2 is arranged on the top side wall of the processing table 1, a cleaning structure 3 is arranged on the top of the processing table 1, and a rotating structure 4 for limiting the position of a computer back panel is arranged between the polishing structure 2 and the cleaning structure 3;

[0040] When the polishing structure 2 moves, it drives the cleaning structure 3 to slide in the direction close to the polishing structure 2. At the same time, the cleaning structure 3 drives the rotating structure 4 to rotate. When the rotating structure 4 rotates, the polishing position of the polishing structure 2 is changed.

[0041] The present invention takes into account that when the existing device performs a polishing operation on the computer back panel, the computer back panel is usually fixed first, and then the polishing device is controlled to reciprocate on the surface of the computer back panel to complete the polishing of the computer back panel. However, in the process of reciprocating polishing of the computer back panel, at both ends of the computer back panel, since the existing device is reciprocating, one side of the computer back panel will be continuously cleaned. Compared with other areas of the computer back panel, the polishing amount at both ends of the computer back panel will be significantly greater, which is easy to cause local over-polishing. Therefore, the present invention drives the cleaning structure 3 to move synchronously with the polishing structure 2 when the polishing structure 2 slides toward the side close to the motor 15, and the cleaning structure 3 cleans the bottom of the polishing structure 2 when it moves. In this process, the cleaning structure 3 also drives the rotating structure 4 to rotate, changing the position of the computer back panel, so that the polishing structure 2 polishes the computer back panel on the side away from the motor 15, thereby avoiding excessive polishing of both ends of the computer back panel.

[0042] An opening and closing door 11 and a sealing door 13 are rotatably connected to one side of the processing table 1. A control panel 12 is installed on the surface of the opening and closing door 11. A cylinder 14 and a motor 15 are installed inside the processing table 1. The control panel 12 is electrically connected to the cylinder 14 and the motor 15.

[0043] The polishing structure 2 includes a connecting frame 21 fixedly connected to the processing table 1, a screw rod 22 is fixedly connected to the output shaft end of the motor 15, a sliding block 23 is connected to the external thread of the screw rod 22, the sliding block 23 is slidably connected to the connecting frame 21, a connecting block 24 is fixedly connected to the bottom of the sliding block 23, and the sliding block 23, the connecting block 24 and the connecting frame 21 are slidably connected.

[0044] A guide groove is provided at the bottom of the connecting frame 21, and a moving block 25 is slidably connected inside the connecting block 24. A connecting column 26 is fixedly connected to the bottom of the moving block 25. The connecting column 26 is slidably connected to the guide groove provided at the bottom of the connecting frame 21. An end of the connecting column 26 away from the moving block 25 is fixedly connected to a mounting block 27. A polishing plate 28 is installed at the bottom of the mounting block 27. A polishing sheet is installed at the bottom of the polishing plate 28. A control component 29 is provided inside the connecting frame 21.

[0045] In order to facilitate the polishing of the computer back panel, refer to Figure 2 , Figure 3 and Figure 4 When polishing the computer back panel, the staff starts the motor 15 electrically connected to it through the control panel 12. After the motor 15 is started, it drives the screw rod 22 fixedly connected to its output shaft end to rotate clockwise. When the screw rod 22 rotates, it drives the sliding block 23 connected to its external thread to slide inside the connecting frame 21 in the direction close to the motor 15. When the sliding block 23 slides, it drives the connecting block 24 to slide inside the connecting frame 21. At this time, the connecting block 24 drives the moving block 25 with internal sliding connection to move synchronously. When the moving block 25 moves, the connecting column 26 fixedly connected to its bottom slides in the guide groove opened at the bottom of the connecting frame 21. Therefore, when the moving block 25 and the connecting column 26 move in the direction close to the motor 15, they will also slide left and right along the shape of the guide groove. At this time, the connecting column 26 drives the polishing plate 28 to slide on the top of the computer back panel through the mounting block 27, and the polishing plate 28 polishes the surface of the computer back panel through the polishing sheet installed at its bottom.

[0046] The present invention takes into account that when polishing the computer back panel, the computer back panel should be closely fitted with the bottom of the polishing sheet, so as to facilitate the polishing of the computer back panel. If the computer back panel and the polishing sheet 28 cannot be adjusted, it will be inconvenient to replace the computer back panel. Figure 3 Because the length of the connecting frame 21 is greater than the length of the limit box 45, and the size of the limit box 45 matches the size of the computer back panel that needs to be polished, when the polishing plate 28 moves to the side close to the motor 15 and is not above the computer back panel, the control panel 12 can be controlled to turn off the motor 15, so that the polished computer back panel can be taken out from the inside of the limit box 45, and then the computer back panel that needs to be polished again is placed inside the limit box 45, so as to facilitate the replacement of the computer back panel.

[0047] A first control switch and a second control switch for controlling the rotation direction of the motor 15 are respectively installed on both sides of the guide slot at the bottom of the connecting frame 21 , and the first control switch and the second control switch are respectively electrically connected to the motor 15 .

[0048] The present invention fully considers that when the computer back panel is polished, the surface of the computer back panel is usually repeatedly polished to ensure that the surface of the computer back panel is thoroughly polished. Figure 5 Because the first control switch and the second control switch for controlling the rotation direction of the motor 15 are respectively installed on both sides of the guide groove opened at the bottom of the connecting frame 21, and the first control switch and the second control switch are electrically connected to the motor 15 and the cylinder 14 respectively, when the connecting column 26 contacts the first control switch on the side away from the motor 15, the motor 15 will rotate clockwise, otherwise, the motor 15 will rotate counterclockwise, so that the polishing plate 28 reciprocates above the limit box 45 through the above description until the computer back panel is polished.

[0049] The cleaning structure 3 includes a moving block 31 slidably connected to the output shaft end of the cylinder 14, a collecting box 3101 is fixedly connected to the top of the moving block 31, a sliding plate 32 is fixedly connected to the side of the moving block 31 away from the cylinder 14, and a first trapezoidal block 33 is fixedly connected below the sliding plate 32.

[0050] A second trapezoidal block 34 is fixedly connected inside the processing table 1;

[0051] The second trapezoidal blocks 34 fit together with the second trapezoidal blocks 34;

[0052] The processing table 1 is provided with a limiting frame which is slidably connected to the sliding plate 32 .

[0053] The size of the collecting box 3101 is larger than that of the polishing plate 28 , and a cleaning sheet is fixedly connected inside the collecting box 3101 .

[0054] The present invention takes into account that when the bottom piece of the polishing plate 28 is used for a long time, if it is frequently replaced, the efficiency of polishing will be reduced, so the bottom of the polishing plate 28 should be cleaned in time. Figure 4 and Figure 5 When the connecting block 24 contacts the control member 29 during the process of sliding toward the side close to the motor 15, a third control switch is installed on the side of the control member 29 close to the connecting block 24, and the control switch is electrically connected to the cylinder 14, so that a signal is output to the cylinder 14 through the third control switch;

[0055] Start the cylinder 14, and the cylinder 14 drives the moving block 31 slidably connected to its output shaft end to slide toward the side close to the cylinder 14. When the moving block 31 slides, it drives the first trapezoidal block 33 to slide toward the side close to the cylinder 14 through the sliding plate 32. After sliding for a distance, the first trapezoidal block 33 fits with the surface of the second trapezoidal block 34, so that the first trapezoidal block 33 drives the collection box 3101 to move upward through the sliding plate 32 and the moving block 31. At the same time, when the first trapezoidal block 33 and the second trapezoidal block 34 are in plane contact, the second trapezoidal block 34 will not squeeze the first trapezoidal block 33 again, so that the collection box 3101 is in a stationary state at this time.

[0056] After the collection box 3101 completes the upward movement, it is at the bottom of the polishing plate 28. The polishing plate 28 moves toward the side close to the cylinder 14, and at this time the polishing plate 28 is still moving left and right. Since the size of the collection box 3101 is larger than the size of the polishing plate 28, the polishing plate 28 slides above the collection box 3101 by moving left and right. The polishing plate 28 and the cleaning sheet fixedly connected inside the collection box 3101 rub against each other, thereby cleaning the polishing sheet at the bottom of the polishing plate 28.

[0057] And when the polishing plate 28 slides toward the side close to the motor 15, the collection box 3101 will follow the polishing plate 28 and slide synchronously toward the direction close to the motor 15 through the cooperation of the moving block 31 and the cylinder 14, so that the horizontal position of the polishing sheet and the collection box 3101 will not change, thereby improving the work efficiency of cleaning the polishing sheet.

[0058] The rotating structure 4 includes a rack 41 arranged inside the sliding plate 32, and a gear 42 is also arranged inside the sliding plate 32. The outer wall of the gear 42 is fixedly connected with a rotating column 43, and the rotating column 43 is located above the rack 41. The bottom of the rotating column 43 is fixedly connected with a rotating plate 44, and the top of the rotating plate 44 is fixedly connected with a limit box 45 for fixing the computer back panel.

[0059] The length of the limit box 45 is smaller than the length of the connecting frame 21 , and the inner size of the limit box 45 is adapted to the size of the computer back panel to be polished.

[0060] The present invention takes into account that during the reciprocating polishing of the computer back panel, the two ends of the computer back panel will be over-polished due to the reciprocating motion of the existing polishing plate 28. Figure 7 , Figure 8 and Fig. 9As shown, when the planes of the first trapezoidal block 33 and the second trapezoidal block 34 are in contact, the moving block 31 drives the collecting box 3101 and the polishing plate 28 to move synchronously, and at this time, the rack 41 inside the sliding plate 32 is meshed with the rotating column 43 fixedly connected to the outer wall of the gear 42. At this time, the sliding plate 32 continues to move and drives the gear 42 to rotate clockwise through the cooperation of the rack 41 and the rotating column 43. When the gear 42 rotates, the computer back panel inside the limit box 45 is driven to rotate through the rotating plate 44 and the limit box 45. When the connecting column 26 rotates counterclockwise through the second control switch on the side of the guide groove close to the motor 15, the connecting block 24 and the polishing plate 28 and other structures synchronously slide to the side away from the motor 15, and the side of the computer back panel away from the motor 15 is cleaned, and when the connecting column 26 squeezes the second control switch installed in the bottom guide groove on the side of the connecting frame 21 close to the motor 15, the cylinder 14 is closed;

[0061] When the polishing plate 28 moves to contact the first control switch on the side away from the motor 15, the first control switch controls the output shaft end of the cylinder 14 to slide toward the side away from the polishing plate 28. At this time, the cylinder 14 drives the first trapezoidal block 33 to slide toward the side away from the motor 15 through the cooperation of the moving block 31 and the sliding plate 32. At this time, the first trapezoidal block 33 is in a plane that is in contact with the second trapezoidal block 34, and the rotating column 43 is engaged with the rack 41. The rack 41 will rotate counterclockwise through the gear 42, so that the rotating column 43 drives the computer back panel inside the limit box 45 to rotate counterclockwise through the rotating plate 44, so as to clean the side of the computer back panel close to the motor 15.
