[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 11 As shown, the present invention provides a technical solution: a controller production and assembly device, comprising two assembly tables 1, a conveying body 2 disposed between the two assembly tables 1, the conveying body 2 being used to convey the housing, horizontal plates 3 symmetrically disposed above the assembly tables 1, a crossbeam frame 4 fixedly connected between the tops of the two horizontal plates 3, an output motor 5 fixedly connected to the bottom of the two crossbeam frames 4, a screw machine 6 fixedly connected to the output shafts of the two output motors 5, a drive mechanism for lifting and lowering the horizontal plates 3 disposed below the two horizontal plates 3, a bracket seat 7 symmetrically fixedly connected to one side of the two horizontal plates 3, a cover plate placed above the bracket seats 7, a correction component disposed on one side of the bracket seat 7, the correction component being used to correct the position of one or both sides of the cover plate, and a push-alignment component disposed at the bottom of the bracket seat 7, the push-alignment component being used to push the other two sides of the cover plate.

[0023] During operation: The cover plate to be installed is placed between multiple mounting brackets 7. The conveyor body 2 transports the housing to the preset installation position, so that the housing is directly below the cover plate. The drive mechanism is activated, which drives the two horizontal plates 3 to descend, and the multiple mounting brackets 7 drive the cover plate to descend as well. During the descent, the cover plate will contact the correction component, which will gradually push the two sides of the cover plate so that the cover plate is exactly in the middle of the two horizontal plates 3 before contacting the housing. After the correction component corrects the position of one side of the cover plate, it will drive the push-alignment component to move. The push-alignment component will correct the position of the other side of the cover plate so that when the cover plate is placed on top of the housing, the screws and screw holes on its side are aligned, making it easy for the screws to be directly driven into the screw holes, thus connecting the cover plate and the housing together and completing the installation. In this assembly process, the screws on the cover plate are lifted when they come into contact with the screw holes. Because the screws are aligned with the holes on the cover plate, they do not become misaligned. When the nut contacts the screw-making machine 6, the output motor 5 automatically starts, driving the screw-making machine 6 to rotate, thus driving the screw into the screw hole. This completes the automatic assembly process of the cover plate and the housing. After assembly, the cover plate and housing are transported away together by the conveyor body 2, ready for the next stage of processing. Through the above embodiment, when the cover plate descends and approaches the housing via the drive mechanism, the correction and pushing components can automatically calibrate the position of the cover plate during this process. The correction and pushing components ensure the alignment accuracy between the cover plate and the housing during descent, ensuring that the screws are always aligned with the screw holes. This avoids the problem of screws not being accurately inserted into the screw holes due to positional deviations, improving the accuracy and efficiency of assembly.

[0024] like Figures 3 to 4 As shown, the correction assembly includes multiple push blocks 8, each push block 8 being slidably connected to the inner wall of each frame plate base 7. A plug rod 11 is fixedly connected to one side of each push block 8. The outer wall of the plug rod 11 is plugged into the inner wall of the horizontal plate 3. A pressing table 10 is fixedly connected to one side of each plug rod 11. The pressing table 10 is frustoconical. A return spring 12 is provided on the outside of each plug rod 11. One end of the return spring 12 is fixedly connected to one side of the horizontal plate 3, and the other end of the return spring 12 is fixedly connected to one side of the pressing table 10. Multiple bending plates 9 are fixedly installed on the top of the assembly table 1. One side of the pressing table 10 is in contact with the inner side of the bending plate 9.

[0025] During operation: When the drive assembly is activated and the horizontal plate 3 is lowered, the extrusion table 10 will descend along the side of the bending plate 9. When the extrusion table 10 descends to the bending area of ​​the bending plate 9, it will be subjected to the extrusion force of the bending part of the bending plate 9. The extrusion force causes the insertion rod 11 to slide in the inner wall of the horizontal plate 3, and causes the push block 8 to slide in the inner wall of the frame seat 7. During the movement, the push block 8 will gradually approach one of the sides of the cover plate. If one end of the cover plate is misaligned during this process, it will be gradually corrected. After the movement is completed, the side of the push block 8 will fit against the two sides of the cover plate, thereby achieving the effect of correcting and positioning one of the two sides of the cover plate. When the horizontal plate 3 rises and resets, the multiple push blocks 8 can also reset simultaneously through the reset spring 12, which facilitates the next correction work.

[0026] like Figures 5 to 6 As shown, the push-alignment assembly includes multiple second-stage support plates 13, which are fixedly installed on the bottom of multiple first-stage support plates 7. The inner walls of the multiple second-stage support plates 13 are slidably connected to inner sliders 14. The tops of two inner sliders 14 are fixedly connected to push blocks 29, and the tops of the other two inner sliders 14 are fixedly connected to hinge seats 20. The inner walls of the hinge seats 20 are hinged to push blocks 31. A magnetic suction assembly is provided on one side of the second-stage support plate 13 to drive the inner sliders 14 to slide on the inner wall of the second-stage support plate 13.

[0027] During operation: After multiple push blocks 8 slide simultaneously inside multiple bracket seats 7 to correct and position the two sides of the cover plate, multiple inner sliders 14 will slide simultaneously in the inner wall of the bracket seat 13 via the magnetic component. During the sliding of the inner sliders 14, push blocks 21 will gradually move. As push blocks 21 move, they will gradually approach the other two sides of the cover plate. If the other end of the cover plate is not in the correct position during this process, it will be gradually corrected. After the movement is completed, the side of push blocks 21 will fit against the other two sides of the cover plate, thereby achieving the effect of correcting and positioning the other two sides of the cover plate.

[0028] like Figures 6 to 7 As shown, the magnetic suction assembly includes multiple magnet blocks 18, which are fixedly connected to the bottom of multiple push blocks 8. Each of the multiple inner sliders 14 has a side connecting block 15 fixedly connected to one side. The side connecting block 15 is made of iron, and the multiple side connecting blocks 15 and the magnet blocks 18 are at the same height.

[0029] During operation: When multiple push blocks 18 move along the inner wall of the support plate 17 to calibrate the position of one or both sides of the cover plate, the magnet block 18 will also move along with the push blocks 18. When the side of the push block 18 is just in contact with the two sides of the cover plate, the magnet block 18 is parallel to the side connecting block 15. The side connecting block 15 and the magnet block 18 are at the same height. Since the side connecting block 15 is made of iron, the magnet block 18 attracts the side connecting block 15, causing the side connecting block 15 to move closer to it. This allows the inner slider 14 to slide inside the support plate 13, achieving the function of pushing and positioning the other two sides of the cover plate.

[0030] like Figures 6 to 7 As shown, a damping rod 16 is fixedly connected to one side of the inner slider 14, and the other end of the damping rod 16 is fixedly connected to the inner side of the support plate 13. A return spring 17 is provided on the outside of the damping rod 16. One end of the return spring 17 is fixedly connected to one side of the inner slider 14, and the other end of the return spring 17 is fixedly connected to the inner side of the support plate 13.

[0031] During operation: When the drive mechanism drives the horizontal plate 3 to rise and reset, the cover plate is already connected to the housing and output through the conveyor body 2 away from the top of the frame plate seat 7. At this time, after the push block 8 is reset, the magnet block 18 is no longer in a parallel position with the side connecting block 15. Therefore, the side connecting block 15 and the inner slider 14 can also be reset under the action of the damping rod 16 and the reset spring 17, which makes it easy to push and use again.

[0032] like Figures 7 to 8 As shown, a connecting rod 22 is fixedly connected to one side of each of the two push blocks 21, and a limiting slider 23 is fixedly connected to one side of each connecting rod 22. A fixing plate 24 is symmetrically fixedly installed on the top of the assembly table 1. The inner wall of the fixing plate 24 is provided with an inner sliding groove 1 25, an inner sliding groove 26, and an inner sliding groove 3 27. The limiting slider 23 is slidably connected to the inner wall of the inner sliding groove 1 25 and is adapted to each other. The width distance between the inner sliding groove 1 25 and the inner sliding groove 26 is the same, and the width distance of the inner sliding groove 3 27 is greater than the width distance of the inner sliding groove 26.

[0033] During operation: When the side block 15 connected to the push block 3 21 slides down the inner wall of the inner slide groove 1 25 before the magnet block 18 slides to parallel position, the limiting slider 23 will slide down during its descent. When the magnet block 18 reaches the parallel position, the limiting slider 23 will slide to the inner slide groove 26 and use suction to push the side block 15 and the inner slider 14 to correct the position of the cover plate. Since the push block 3 21 is hinged to the hinge seat 20, the limiting slider 23 will not rotate under the restriction of the inner slide groove 26 when the push block 3 21 is correcting the position of the cover plate. Therefore, the push block 3 21 cannot rotate, thus preventing the side of the push block 3 21 from pushing the cover plate to correct its position. When push block 3 21 rotates at an articulation point, the positions of the two sides of the cover plate cannot be corrected. After push block 3 21 pushes the cover plate into position, the limiting slider 23 slides to the inner slide groove 3 27. At this time, the cover plate screws are threaded into the screw holes of the housing to assemble the two together. When the housing is transported away by the conveying body 2, the cover plate and the housing can be transported out together. During the transport, the cover plate will squeeze push block 3 21 to cause it to rotate at an articulation point. Because the width of the inner slide groove 3 27 is large, the limiting slider 23 can rotate at the inner slide groove 3 27, which can achieve the articulation between push block 3 21 and the articulation seat 20, and smoothly transport the cover plate and the housing away together, achieving the effect of quick removal after the cover plate and the housing are assembled.

[0034] like Figures 6 to 7 As shown, one side of each of the two inner sliders 14 is fixedly connected to a receiving plate 28. Angle springs 30 are fixedly connected between the two receiving plates 28 and the two push blocks 21 respectively. A damping rod 29 is provided on the outside of the angle springs 30. The two ends of the damping rod 29 are fixedly connected to the side of the push block 21 and the top of the receiving plate 28 respectively.

[0035] During operation: When the cover plate and the housing are conveyed away together, the side of the cover plate will press the push block 3 21 to rotate 90 degrees. When the push block 3 21 rotates, it will press the damping rod 29 to deform. After the cover plate leaves, the push block 3 21 can immediately reset under the action of the damping rod 29 and the angle spring 30. When resetting, the limit slider 23 rotates to reset. When the entire horizontal plate 3 rises and resets, the limit slider 23 can still reset along the inner wall of the inner slide groove 26 and the inner slide groove 1 25, which facilitates the subsequent push-and-align operation.

[0036] like Figures 9 to 10As shown, two mounting seats 36 are symmetrically fixedly installed on the top of the assembly table 1. Each mounting seat 36 has an internal threaded slider 37 slidably connected to its inner wall. The outer wall of the threaded conveying rod 38 is threadedly connected to the inner wall of the internal threaded slider 37. Each internal threaded slider 37 has a push plate 39 fixedly connected to its top. A transmission assembly for driving the threaded conveying rod 38 to rotate is provided on one side of the horizontal plate 3.

[0037] During operation: When the horizontal plate 3 descends, it drives multiple threaded conveying rods 38 to rotate through the transmission component. When multiple threaded conveying rods 38 rotate simultaneously, they drive the internal threaded slider 37 to slide on the inner wall of the mounting base 36. During the sliding of the internal threaded slider 37, the push plates 39 on both sides move closer to the housing at the same time to clamp and position the housing, so as to avoid the positional displacement during the descent and assembly of the cover plate, which would cause the screws and screw holes to be misaligned.

[0038] like Figures 9 to 10 As shown, gears 33 are fixedly connected to one side of each of the two internal threaded sliders 37, rack plates 32 are fixedly connected to one side of each of the two horizontal plates 3, the teeth of the rack plates 32 mesh with the teeth of the gears 33, a transmission ring 34 is fixedly connected to one side of each threaded conveying rod 38, and a transmission belt 35 is connected between the outer walls of every two transmission rings 34.

[0039] During operation: When the horizontal plate 3 descends, it drives the gear 33 to rotate through the rack plate 32. When the gear 33 rotates, it drives one of the threaded conveying rods 38 to rotate, and drives the other threaded conveying rod 38 to rotate through the transmission ring 34 and the transmission belt 35. This allows the horizontal plate 3 to descend and bring the cover plate close to the shell, while also clamping and positioning the shell part.

[0040] like Figure 3 and Figure 9 As shown, the drive assembly includes two telescopic cylinders 31, which are fixedly installed on the top of the two assembly platforms 1 respectively, and the output ends of the two telescopic cylinders 31 are fixedly connected to the bottom of the two horizontal plates 3 respectively.

[0041] During operation: By connecting the horizontal plate 3 to the output end of the telescopic cylinder 31, the telescopic cylinder 31 controls the horizontal plate 3 to move up and down, completing the assembly process of the entire cover plate and the housing.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
