Description

Technical Field

[0001] This application relates to the technical field of folding case assembly, and in particular to a folding case assembly machine. Background Technology

[0002] Traditional folding case assembly relies heavily on manual labor or semi-automated equipment, resulting in low efficiency, high labor intensity, and difficulty in ensuring clamping and centering accuracy. While some existing automated equipment can perform some functions, their clamping mechanisms often require independent drive sources and control units, leading to complex structures, high manufacturing costs, and a lack of effective force feedback control during clamping. This can easily damage the case or the equipment itself due to excessive clamping force, making it difficult to meet the needs of efficient, accurate, and safe automated production. Summary of the Invention

[0014] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0015] See Figure 1-4 A folding box assembly machine includes a base plate 1. Limiting guide rails 6 are fixedly connected to the front and rear sides of the top of the base plate 1. A first support plate 7 is fixedly connected to the top of the limiting guide rails 6. An L-shaped support plate 9 is fixedly connected to the right side of the first support plate 7. An electric telescopic device 18 is fixedly connected to the left side of the L-shaped support plate 9. Linear guide rail frames 12 are fixedly connected to the front and rear sides of the bottom right side of the first support plate 7. A toothed plate 17 is fixedly connected to the inner side of the linear guide rail frame 12. A second support plate 19 is fixedly connected to the extended end of the electric telescopic device 18. The right side of the second support plate 19... A third support plate 21 is fixedly connected to the side; a first screw 20 is rotatably connected to the inner wall of the third support plate 21. There are two first screws 20, which are symmetrically distributed front and back. A moving block 23 is threadedly connected to the surface of the first screw 20. The surface of the moving block 23 is slidably connected to the inner wall of the second support plate 19. A clamping plate 24 is fixedly connected to the left side of the moving block 23. A contact sensor 25 is installed on the inner side of the clamping plate 24. A gear 22 is fixedly connected to the outer end of the first screw 20. The bottom of the gear plate 17 meshes with the surface of the gear 22. During assembly, the electric telescopic device 18 extends first, pushing the second support plate 19 and the third support plate 21 to move to the right as a whole. Since the gear 22 at the end of the first screw 20 fixed to the third support plate 21 meshes with the stationary toothed plate 17, the gear 22 is forced to rotate by the toothed plate 17 during linear movement, thereby driving the first screw 20 to rotate. The rotation of the first screw 20 causes the moving block 23, which is threaded to it, to slide inward along the inner wall of the second support plate 19, thereby pushing the left and right clamping plates 24 to move synchronously towards each other, achieving automatic centering of the folding box. The clamping function requires no additional drive throughout the process. When the contact sensor 25 on the inner side of the clamping plate 24 touches the folding box body, the sensor sends a signal to control the electric telescopic device 18 to stop extending immediately, thereby preventing excessive clamping force from causing deformation of the box body or damage to the equipment. This achieves intelligent protection during the clamping process. After clamping is completed, the equipment can be used for subsequent assembly or transfer operations. During unloading, the electric telescopic device 18 retracts, the gear 22 rolls in the opposite direction along the toothed plate 17, driving the first screw 20 to reverse, causing the moving block 23 and the clamping plate 24 to release the box body outward. The reset is convenient and the degree of automation is high.

[0016] A connecting frame 2 is fixedly connected to the top of the base plate 1. A first motor 5 is fixedly installed on the top of the connecting frame 2. A second screw 3 is fixedly connected to the output end of the first motor 5 through a coupling. A lifting platform 4 is threadedly connected to the surface of the second screw 3. The surface of the limiting guide rail 6 is slidably connected to the inner wall of the lifting platform 4. A second motor 8 is fixedly installed on the top of the first support plate 7. A rotating arm 10 is fixedly connected to the output end of the second motor 8 through a coupling. Electromagnetic chucks 11 are fixedly connected to the left and right sides of the bottom of the rotating arm 10. A movable guide rail platform 14 is provided at the bottom of the first support plate 7. A first mover 13 is installed on the guide rail of the linear guide rail frame 12. The left side of the first mover 13 is fixedly connected to the right side of the movable guide rail platform 14. Two second movers 15 are installed on the guide rail of the movable guide rail platform 14. The two second movers 15 are symmetrically distributed on the left and right. A support plate 16 is fixedly connected to the top of the second mover 15. When the equipment starts, the first motor 5 drives the second screw 3 to rotate, causing the lifting platform 4 to rise along the limit guide rail 6, raising the folding box panel placed on it to a predetermined height. Then, the second motor 8 starts, driving the electromagnetic chuck 11 to move through the rotating arm 10, accurately adsorbing the folding box panel and rotating it to the top of the moving guide rail platform 14. The second mover 15 on the moving guide rail platform 14 adjusts the longitudinal position of the support plate 16 to place it in the optimal support position. The electric telescopic device 18 pushes the second support plate 19 to the right, driving the first screw 20 to rotate through the meshing of the gear 22 and the toothed plate 17, causing the moving block 23 to drive the clamping plate 24 to move. The system moves upwards to stably clamp the suspended folding box panel. After clamping, the support plate 16 rises under control. At this time, a tray is placed on the support plate 16. The rising action allows the lower end of the clamped folding box panel to be accurately inserted into the reserved slot or structure on the side of the tray, realizing the initial insertion and assembly of the box body and the base plate. After the insertion is completed, the electromagnetic chuck 11 is released, the clamping plate 24 is retracted, and the support plate 16 carries the assembled box body down to reset. All execution units, including the lifting platform 4 and the rotating arm 10, return to their initial positions, ready for the next assembly cycle. The entire process is precisely controlled through sensor feedback to ensure insertion reliability and assembly efficiency.

[0017] Before operation, the body panels of the folding box are placed on the lifting platform 4, and the tray (i.e., the bottom plate of the folding box) is placed on the support plate 16. After starting the equipment, the first motor 5 drives the second screw 3 to rotate, causing the lifting platform 4 to rise vertically along the limit guide rail 6, raising the body panels to a predetermined height for subsequent gripping operations. The second motor 8 starts, driving the rotating arm 10 to rotate, moving the electromagnetic chuck 11 at its bottom above the lifting platform 4 and adsorbing the body panels. The second motor 8 then drives the rotating arm 10 to reverse, accurately transferring the adsorbed body panels to the predetermined assembly position above the moving guide rail platform 14. The electric telescopic device 18 extends, pushing the second support plate 19 and its entire clamping mechanism to move to the right along the linear guide rail frame 12. The fixedly connected toothed plate 17 forces the gear 22 to rotate, driving the two first screws 20 synchronously. Rotation causes the moving block 23, threadedly connected to the first screw 20, to move in the opposite direction, closing the clamping plate 24 and firmly clamping the suspended box panel. The contact sensor 25 confirms the clamping, and the first mover 13 starts, moving upward along the guide rail of the linear guide frame 12. The moving guide platform 14 pushes the second mover 15 and the support plate 16 on it to rise as a whole, so that the tray can be accurately inserted and combined with the bottom of the clamped box panel, completing the core assembly. After the assembly is completed, the electromagnetic chuck 11 is de-energized and released. The clamping plate 24 is released by reverse drive through the gear and rack mechanism during the retraction of the electric telescopic device 18. The first mover 13 drives the support plate 16 to descend and reset. The lifting platform 4 also descends to the initial position under the drive of the first motor 5. All actuators return to the starting state, ready to start the next work cycle, realizing continuous automated assembly.

[0018] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
