Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a copper strip stamping equipment. Background Technology

[0002] Copper strip generally refers to a strip-shaped material made of pure copper or copper alloys. It has excellent electrical conductivity, thermal conductivity, and corrosion resistance, and is widely used in electronics, power, automotive, and home appliance industries. When the thickness of copper strip is less than 200μm, it is usually referred to as copper foil.

[0003] Currently, to ensure that the copper strip does not shift due to stress during the stamping process, the conveyor seat of copper strip stamping equipment is usually equipped with several limiting shafts. Traditional limiting shafts mainly consist of a shaft body and several limiting plates, with each limiting plate symmetrically distributed on both sides of the copper strip around the center, serving to constrain the copper strip. However, since existing limiting plates are usually directly fixed to the roller body using fasteners such as bolts, the spacing between adjacent limiting plates is affected by the spacing between the threaded holes on the roller body. This makes it difficult to adapt to copper strips of various widths, resulting in the stamping equipment only being able to process one or a few sizes (with multiple threaded holes), thus limiting the application range of the stamping equipment. Utility Model Content

[0004] This invention proposes a copper strip stamping equipment, which solves the problem that stamping equipment in related technologies can only process copper strips of a certain size, thus expanding the application range of stamping equipment.

[0005] The technical solution of this utility model is as follows:

[0006] A copper strip stamping device includes a conveyor seat, on which a limiting mechanism is provided. The limiting mechanism includes a limiting shaft, a plurality of limiting plates, and a moving structure for controlling the movement of each limiting plate on the limiting shaft. The moving structure includes a first lead screw, a second lead screw, and a driving assembly for driving the first lead screw and the second lead screw to rotate. Each of the limiting plates is respectively connected to the first lead screw and the second lead screw.

[0007] Furthermore, a connecting rod is provided between the first lead screw and the second lead screw, and the connecting rod, the first lead screw, and the second lead screw are coaxially arranged, with the thread characteristics on the second lead screw being opposite to those on the first lead screw.

[0008] Furthermore, the connecting rod is provided with an auxiliary pressing structure, which includes a rotating ring and an auxiliary pressing body. The rotating ring is rotatably connected to the connecting rod, and the auxiliary pressing body is detachably connected to the rotating ring.

[0009] Furthermore, the diameters of the first lead screw and the second lead screw are both greater than the diameter of the connecting rod, and the outer ring diameter of the rotating ring is less than or equal to the diameters of the first lead screw and the second lead screw.

[0010] Furthermore, the rotating ring is provided with a connecting hole, and the auxiliary pressing body is provided with a matching countersunk hole. The matching countersunk hole is provided with a fixing member for fixing the auxiliary pressing body on the rotating ring, and the fixing member is threadedly connected to the connecting hole.

[0011] Furthermore, the auxiliary pressure body includes a first part and a second part. Both ends of the first part and the second part are respectively provided with a first mating plate and a second mating plate for mutual cooperation. Each of the first mating plate and the second mating plate has a first mating hole and a second mating hole.

[0012] Furthermore, at least two connecting holes are provided, and each connecting hole is symmetrically distributed on the radial surface of the rotating ring with the axis of the rotating ring as the center. Each connecting hole, the first mating hole, and the second mating hole are coaxially arranged in a one-to-one correspondence.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] The conveyor seat of this utility model is equipped with a limiting mechanism, which mainly includes a limiting shaft and several limiting plates. Simultaneously, a moving structure is specifically provided for controlling the movement of each limiting plate on the limiting shaft. The moving structure mainly includes a first lead screw, a second lead screw, and a driving assembly for driving the first and second lead screws to rotate. Each limiting plate is respectively connected to the first and second lead screws. That is, in this embodiment, the distance between adjacent limiting plates can be adjusted by controlling the rotation of the first and second lead screws through the driving assembly. This adjustment method differs from traditional adjustment methods, as it is not affected by the threaded holes on the limiting shaft. The adjustment method is more flexible and has a larger adjustment range, effectively improving the processing and production range of the stamping equipment.

[0015] Furthermore, through the cooperation of the first lead screw or the second lead screw with the limiting shaft (the copper strip conveying path on the conveyor seat passes through the distance between the radial surface of the first lead screw or the second lead screw and the radial surface of the limiting shaft), the first lead screw or the second lead screw can, to a certain extent, constrain the copper strip, preventing the subsequent copper strip from arching upwards due to force when the stamping equipment breaks the copper strip, thus ensuring the stability and safety of the copper strip conveying.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] This embodiment proposes a copper strip stamping equipment, mainly including a conveyor seat 1. The conveyor seat 1 is equipped with a limiting mechanism 2 and a stamping mechanism. That is, the limiting mechanism 2 limits the copper strip to ensure that the copper strip accurately enters the stamping mechanism for stamping. In this embodiment, the stamping mechanism preferably includes a conventional stamping mechanism with a stamping die and an eccentric wheel drive assembly. That is, the stamping mechanism in this embodiment is the prior art. The specific structure of the stamping mechanism should be determined according to the type of stamping mechanism actually selected. This embodiment will not elaborate further.

[0027] The limiting mechanism 2 mainly includes a limiting shaft 21 and several limiting plates 22. Each limiting plate 22 is located on the limiting shaft 21. At the same time, the conveying seat 1 is also specifically provided with a moving structure 3 for controlling the movement of each limiting plate 22 on the limiting shaft 21. That is, in this embodiment, the limiting plate 22 is not fixed to the limiting shaft 21 by fasteners such as bolts, but is slidably connected to the limiting shaft 21 by the moving structure 3.

[0028] Specifically, the moving structure 3 in this embodiment mainly includes a first lead screw 31, a second lead screw 32, and a drive assembly 33 for driving the first lead screw 31 and the second lead screw 32 to rotate. Each limiting plate 22 is slidably connected to the limiting shaft 21 and is also connected to the first lead screw 31 and the second lead screw 32 respectively. That is, by rotating the first lead screw 31 and the second lead screw 32, the distance between adjacent limiting plates 22 can be adjusted. Compared with the traditional way of adjusting the limiting plates 22, it is not affected by the threaded hole on the limiting shaft 21. The adjustment method is more flexible and the adjustment range is larger, which effectively improves the processing and production range of the stamping equipment.

[0029] Preferably, in this embodiment, the driving component 33 is a driving motor, which is fixed on the conveying seat 1 to ensure that it can stably provide driving force. A connecting rod 34 is provided between the first lead screw 31 and the second lead screw 32. The two ends of the connecting rod 34 are respectively fixedly connected to the first lead screw 31 and the second lead screw 32. The fixed connection between the first lead screw 31, the second lead screw 32, and the connecting rod 34 is preferably integrally formed to ensure the connection strength between the three. The connecting rod 34, the first lead screw 31, and the second lead screw 32 are coaxially arranged, and the diameter of the first lead screw 31 should be the same as the diameter of the second lead screw 32 to ensure the balance of the overall structure. The thread characteristics on the second lead screw 32 are opposite to those on the first lead screw 31. Thus, by simply linking the first lead screw 31 or the second lead screw 32 with the output shaft of the driving motor, the limiting plates 22 located on the first lead screw 31 and the second lead screw 32 can move simultaneously in opposite directions to complete the spacing adjustment.

[0030] In this embodiment, the drive motor should preferably be a stepper motor or other motor with self-locking performance to prevent the three-way combination structure of the first lead screw 31, the second lead screw 32, and the connecting rod 34 from rotating when the drive motor is not started, thereby driving the limit plate 22 to move, and ensuring the structural stability and reliability of this embodiment in the working state.

[0031] Furthermore, while adjusting the position of the limiting plate 22 by relying on the screw drive, the copper strip conveying path should just pass between the radial surface of the connecting rod 34 and the radial surface of the limiting shaft 21. In this way, the connecting rod 34, the first screw 31, and the second screw 32 can also constrain the copper strip to a certain extent, preventing the copper strip from arching unexpectedly due to stamping stress, thus ensuring the stability of the copper strip conveying and the safety of the copper strip processing.

[0032] Meanwhile, the connecting rod 34 is provided with an auxiliary pressing structure 4, which includes a rotating ring 41 and an auxiliary pressing body 42. The rotating ring 41 is rotatably connected to the connecting rod 34, and the auxiliary pressing body 42 is located on the rotating ring 41. This allows the copper strip to simultaneously contact the auxiliary pressing body 42 and the limiting shaft 21 when passing between the connecting rod 34 and the limiting shaft 21. Through the mutual cooperation between the auxiliary pressing body 42 and the limiting shaft 21, and the mutual cooperation between adjacent limiting plates 22, the left-right and up-down vibration and offset of the copper strip are reduced, further ensuring the stability of the copper strip's conveying process in this embodiment. Furthermore, the auxiliary pressing body 42 should be detachably connected to the rotating ring 41 so that when processing copper strips of different thicknesses, the corresponding size (diameter) of the auxiliary pressing body 42 can be replaced to adapt to copper strips of various thicknesses, effectively ensuring the applicability of this embodiment.

[0033] Furthermore, due to the rotational connection between the rotating ring 41 and the connecting rod 34, the auxiliary pressure body 42 will rotate after being subjected to the force from the forward movement of the copper strip, thereby dispersing the force transmitted to the auxiliary pressure body 42 and making the overall structure of this embodiment more stable.

[0034] Preferably, the diameter of the auxiliary pressure body 42 should be greater than the diameters of the first lead screw 31 and the second lead screw 32. In this way, the auxiliary pressure body 42 can also constrain the movement distance of each limiting plate 22 and prevent the limiting plate 22 from detaching from the first lead screw 31 or the second lead screw 32 during movement.

[0035] Specifically, the rotating ring 41 is provided with a connecting hole 411, and the auxiliary pressing body 42 is provided with a matching countersunk hole 421. The matching countersunk hole 421 is provided with a fixing member 43 for fixing the auxiliary pressing body 42 on the rotating ring 41. The fixing member 43 is threadedly connected to the connecting hole 411. At the same time, with the countersunk hole feature of the matching countersunk hole 421, the fixing member 43 can be submerged in the radial surface of the auxiliary pressing body 42, so as to avoid the fixing structure used to fix the auxiliary pressing body 42 on the rotating ring 41 from interfering with the copper strip and the limiting shaft 21 during the rotation of the auxiliary pressing body 42, thereby affecting the normal rotation of the auxiliary pressing body 42 or causing the copper strip to deform.

[0036] In this embodiment, the fastener 43 is preferably a commonly available threaded fastener such as a bolt, so that a replacement can be quickly found if the fastener 43 is accidentally lost.

[0037] Meanwhile, to facilitate the assembly and disassembly of the auxiliary pressure body 42 onto the rotating ring 41, the auxiliary pressure body 42 in this embodiment includes a first part 422 and a second part 423, meaning the auxiliary pressure body 42 itself is a spliced ​​structure. Specifically, both ends of the first part 422 and the second part 423 are respectively provided with a first mating plate 4221 and a second mating plate 4231 for mutual cooperation. Each of the first mating plates 4221 and the second mating plate 4231 has a first mating hole 4211 and a second mating hole 4212, respectively. That is, during the process of installing the auxiliary pressure body 42 onto the rotating ring 41, the first part 422 and the second part 423 can be placed on both sides of the rotating ring 41, with both facing the rotating ring 41. Pushing in the direction of 1 causes the projection surfaces of the first mating plate 4221 and the second mating plate 4231 on the horizontal plane to coincide, and the central axes of the first mating hole 4211 and the second mating hole 4212 to coincide, forming a mating countersunk hole 421. A fixing member 43 is then inserted into the mating countersunk hole 421, and the fixing member 43 is threadedly connected to the connecting hole 411, completing the installation of the auxiliary pressure body 42 on the rotating ring 41. Conversely, pushing in the opposite direction completes the disassembly of the auxiliary pressure body 42 on the rotating ring 41. Thus, in this embodiment, the auxiliary pressure body 42 does not need to be installed or disassembled by sliding from the axial end face of the first lead screw 31 or the second lead screw 32 to the rotating ring 41 in a sleeve manner. Different sizes of auxiliary pressure bodies 42 can be replaced without removing the moving structure 3 from the conveying seat 1, improving the replacement efficiency of the auxiliary pressure body 42.

[0038] In order to ensure the stability of the auxiliary pressure body 42 on the rotating ring 41, at least two connecting holes 411 are provided. Each connecting hole 411 is symmetrically distributed on the radial surface of the rotating ring 41 with the axis of the rotating ring 41 as the center. Each connecting hole 411, the first mating hole 4211, and the second mating hole 4212 are coaxially arranged in a one-to-one correspondence. Each connecting hole 411 is fixed with a fixing member 43, thereby ensuring that both ends of the first mating plate 4221 and the second mating plate 4231 can be fixed.

[0039] The diameters of the first lead screw 31 and the second lead screw 32 are both larger than the diameter of the connecting rod 34. That is, after the first lead screw 31, the second lead screw 32, and the connecting rod 34 are integrally formed, the longitudinal section of the combined structure can present an "H" shape, that is, an I-shaped structure, so that the combined structure has good bending resistance and strength, thereby ensuring that each limiting plate 22 moves stably on the first lead screw 31 or the second lead screw 32. The outer ring diameter of the rotating ring 41 is less than or equal to the diameter of the first lead screw 31 and the second lead screw 32. That is, the end faces of the first lead screw 31 and the second lead screw 32 can constrain the rotating ring 41, preventing the rotating ring 41 from shifting during the operation of this embodiment, and ensuring the stability of the operation of this embodiment.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
