[0021] Compared with the prior art, the present invention provides an automatic processing device for mobile phone middle plate, which has the following beneficial effects:

[0022] The mobile phone mid-plate automatic processing equipment can unload the finished mobile phone mid-plate through the first conveyor, and can load the mobile phone mid-plate to be processed through the second conveyor. The second conveyor can be driven by starting the servo motor. When the second conveyor is driven, the pulley and belt on the right side can be driven to rotate. At this time, the mobile phone mid-plate on the top of the second conveyor can be dusted by the exhaust fan, and the waste and dust contained therein can be cleaned so that they can enter the inner cavity of the collection box. This structure can clean the mobile phone mid-plate when loading it, thereby improving the quality of the subsequent finished mobile phone mid-plate.

[0023] The mobile phone middle plate automatic processing equipment can drive the first gear at the bottom through the belt and pulley on the left side. After the first gear at the bottom is rotated, it can mesh with the first gear at the top. At this time, the two brush rollers can be driven to rotate. When the mobile phone middle plate moves between the two brush rollers, the top and bottom of the mobile phone can be cleaned at the same time, which can further improve the cleanliness of the mobile phone middle plate. At the same time, the mobile phone middle plate can continue to move into the inner cavity of the equipment frame.

[0024] The mobile phone middle plate automatic processing equipment can clamp the mobile phone middle plate to be processed through the pneumatic clamping jaws, and can mark it in cooperation with the laser marking machine body. By starting the rotating cylinder, the mobile phone middle plate can be driven to flip through the pneumatic clamping jaws. By starting the hydraulic push rod, the position of the mobile phone middle plate can be adjusted. By starting the linear motor, the mobile phone middle plate can be driven to move longitudinally in cooperation with the driving block and the first movable block, so as to meet the demand for marking the mobile phone middle plate. This structure can adjust the mobile phone middle plate in multiple positions. When marking the laser marking machine body, the outer wall of the mobile phone middle plate can be marked in all directions. By starting the rotating motor, the pneumatic clamping jaws can be driven to rotate, which is convenient for adjusting the marking position of the mobile phone middle plate and moving it to the top of the first conveyor for unloading.

[0025] The mobile phone mid-plate automatic processing equipment can load the mobile phone mid-plate through the provided loading rack, can limit the right side of the mobile phone mid-plate through the provided second side limit component, can clamp and limit the two ends of the mobile phone mid-plate through the provided two end limit components, can limit the left side of the mobile phone mid-plate through the provided first side limit component, and can store multiple mobile phone mid-plates when marking the mobile phone mid-plate, and can straighten their positions at the same time, so as to facilitate the subsequent pneumatic clamping work.

[0026] The mobile phone middle plate automatic processing equipment facilitates the mobile phone middle plate to move to the top of the loading frame through the limit block connected by the torsion shaft, and the limit pile arranged at the bottom of the second side limit assembly can limit the limit block so that it cannot move to the right side, so that the right side of the mobile phone middle plate can be limited, and the lifting plate can be driven to rise or fall by starting the set hydraulic lifting rod. When rising, the mobile phone middle plate on the top can be moved. When marking it, it can be raised by the thickness of the mobile phone middle plate at a time, so as to facilitate the pneumatic clamping to clamp it, and the rollers on the outer walls of the two end limit assemblies, the first side limit assembly and the second side limit assembly can be used to prevent the outer wall of the mobile phone middle plate from being worn when it moves, so that it can rise or fall normally.

[0027] The mobile phone middle plate automatic processing equipment can drive the bidirectional screw to rotate by starting the set driving motor, so that the second movable block on the right side can be threadedly connected with it. At this time, the two end limit assemblies at both ends can be driven to move by the movable rod until the two end limit assemblies are attached to the two ends of the mobile phone middle plate through the rollers on their outer walls. At this time, the two ends of the mobile phone middle plate can be limited.

[0028] The mobile phone middle plate automatic processing equipment can fit on the right side of the C-shaped frame in normal state through the arranged rack. When the bidirectional lead screw rotates, it will drive the second gear to rotate, so that the second gear will mesh with the rack. At this time, the rack can be driven to move left and right. When it moves to the right, the C-shaped frame can be contracted to the right side through the arranged contraction spring, so that the C-shaped frame can drive the first side limit assembly to move to the right side, so that it can fit on the left side of the mobile phone middle plate. At this time, the limiting work on the left side of the mobile phone middle plate can be completed.

[0029] The mobile phone middle plate automatic processing equipment can simultaneously drive the two end limit assemblies and the first side limit assembly to move by driving the bidirectional screw rod, so that the left sides of the two ends of the mobile phone middle plate can be limited at the same time. The C-shaped frame can be retracted to the right side at any time by the set contraction spring, but the C-shaped frame will be limited by the set rack in normal state, and the first side limit assembly can be driven to move at the same time when the two end limit assemblies are driven.

[0030] The mobile phone middle plate automatic processing equipment, through the provision of movable grooves and springs, enables the first side limit assembly to have a certain degree of mobility, so that the first side limit assembly can move in a larger range. After the two end limit assemblies are attached to the two ends of the mobile phone middle plate, the movement range of the first side limit assembly can be greater than that of the C-shaped frame, which can further ensure the limiting effect on the left side of the mobile phone middle plate.

[0031] The mobile phone mid-plate automatic processing equipment can adjust the position of the mobile phone mid-plate at multiple angles and positions according to the marking requirements when laser marking is performed on the mobile phone mid-plate, and is convenient for loading and unloading. The mobile phone mid-plate can be cleaned while loading, so as to ensure the quality of the finished product. Through the set loading rack, multiple mobile phone mid-plates can be loaded, and they can be limited all around. At the same time, they can be automatically straightened while limiting, so as to facilitate the pneumatic clamp to clamp them. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the limit pile arranged at the bottom of the second side limit assembly 45 can limit the limit block 46 so that it cannot move to the right side, so that the right side of the mobile phone middle plate can be limited. By starting the hydraulic lifting rod 34, the lifting plate 33 can be driven to rise or fall. When rising, the mobile phone middle plate on the top can be moved.

At this time, the limiting work on the left side of the middle plate of the mobile phone can be completed.

[0050] By driving the bidirectional screw rod 29, the two end limit assemblies 23 and the first side limit assembly 37 can be driven to move at the same time, so that the left sides of the two ends of the mobile phone middle plate can be limited at the same time. By the set contraction spring 44, the C-shaped frame 39 can be contracted to the right side at any time, but by the set rack 31, the C-shaped frame 39 will be limited in normal state, and when the two end limit assemblies 23 are driven, the first side limit assembly 37 can be driven to move at the same time.

[0051] By setting the movable groove 40 and the spring 42, the first side limit component 37 has a certain degree of mobility, so that the first side limit component 37 can move in a larger range. After the two end limit components 23 are attached to the two ends of the mobile phone middle plate, the moving range of the first side limit component 37 can be larger than the C-shaped frame 39, which can further ensure the limiting effect on the left side of the mobile phone middle plate.

[0052] When laser marking is performed on the mobile phone middle plate, the position of the mobile phone middle plate can be adjusted at multiple angles and positions according to the marking requirements, and it is convenient to load and unload the material. The mobile phone middle plate can be cleaned while loading, so as to ensure the quality of the finished product. Through the set loading rack 47, multiple mobile phone middle plates can be loaded, and they can be limited all around. At the same time, they can be automatically straightened while limiting, so as to facilitate the pneumatic clamp 7 to clamp them.

[0053] It should be noted that the present invention is an automatic processing equipment for mobile phone middle plates. When in use, the mobile phone middle plate to be processed is placed on the right side of the top of the second conveyor 14, and the servo motor 15 is started to drive the second conveyor 14 to work. While the second conveyor 14 is working, it will drive the pulleys 18 and belts 19 on both sides to work. The pulleys 18 and belts 19 on the right side can drive the exhaust fan 17. The exhaust fan 17 can then draw dust and other debris contained in the mobile phone middle plate into the inner cavity of the collection box 16. When the mobile phone middle plate moves to the left side of the second conveyor 14, it will move between the two brush rollers 21 through the guide plate 22. The pulleys 18 and belts 19 on the left side will drive the first gear 20 at the bottom to rotate. At this time, the first gear 20 at the bottom will mesh with the first gear 20 at the top, thereby driving the two brush rollers 21 to rotate. When the mobile phone middle plate passes between the two brush rollers 21, its top and bottom can be cleaned.

[0054] After being cleaned by the brush roller 21, the mobile phone middle plate will move to the right side of the limit block 46. After the mobile phone middle plate contacts the limit block 46, it will squeeze it to the left. At this time, the two brush rollers 21 will play a feeding role on the mobile phone middle plate. After squeezing, the limit block 46 will rotate to the left. When the mobile phone middle plate is completely placed on the top of the loading rack 47, the limit block 46 is reset and is on the right side of the mobile phone middle plate.

[0055] Start the driving motor 27 to drive the bidirectional screw 29 to rotate. At this time, the second movable block 28 on the right side will be threadedly connected with the bidirectional screw 29. At this time, the movable rods 25 at both ends will drive the two end limit assemblies 23 to move to the opposite side until they are attached to the two ends of the mobile phone middle plate.

[0056] When the bidirectional screw rod 29 rotates, the second gear 30 is driven to rotate, and the second gear 30 is meshed with the rack 31, so that the rack 31 can move to the right. When the left side of the rack 31 is separated from the C-shaped frame 39, the contraction spring 44 will contract the C-shaped frame 39 to the right, thereby driving the first side limit assembly 37 to move to the right through the extension frame 38 until the first side limit assembly 37 is attached to the left side of the mobile phone middle plate. At this time, the first side limit assembly 37, the second side limit assembly 45 and the two end limit assemblies 23 can limit the four sides of the mobile phone middle plate.

[0057] When there is still a certain position between the first side limit assembly 37 and the left side of the mobile phone middle plate, the spring 42 will move the first side limit assembly 37 to the right through the extension frame 38, so that the first side limit assembly 37 can limit the right side of the mobile phone middle plate;

[0058] When the first side limit assembly 37 is already attached to the two end limit assemblies 23 but is still moving, the first side limit assembly 37 will drive the extension frame 38 to move to the left, thereby achieving an adaptation effect;

[0059] Start the hydraulic lifting rod 34 to raise the lifting plate 33 until the top mobile phone middle plate is moved to the pneumatic clamp 7, start the pneumatic clamp 7 to clamp the mobile phone middle plate, reset the lifting plate 33, adjust the mobile phone middle plate according to the position to be processed, start the hydraulic push rod 9, the rotary cylinder 8, the linear motor 6 and the rotary motor 10 to adjust the mobile phone middle plate in all directions, and after adjusting to the appropriate position, start the laser marking machine body 3 to mark the mobile phone middle plate;

[0060] After the marking is completed, the rotating motor 10 is started, the pneumatic clamp 7 is rotated to the top of the first conveyor 4, and the pneumatic clamp 7 is released. At this time, the finished mobile phone middle plate can fall on the top of the first conveyor 4, and the first conveyor 4 is started to unload it.
