Description

Technical Field

[0001] This invention relates to the field of clamp manufacturing, and specifically to a clamp manufacturing process. Background Technology

[0002] With the continuous progress of the times and the rapid development of science and technology, new energy technologies have gradually matured and become increasingly sophisticated. Among the many new energy technologies, the application of new energy batteries has become increasingly widespread, playing a crucial role in electric vehicles, energy storage systems, and portable electronic devices. Battery clamps, as key components for connecting and securing battery modules, are undeniably important. Battery clamps not only need to ensure the stability and safety of battery modules under various operating conditions but also need to adapt to the demands of automated production lines to improve production efficiency. Therefore, the level of automation in the battery clamp manufacturing process directly affects the quality and production efficiency of the final product, making it an indispensable part of the new energy battery manufacturing process.

[0003] Existing clamp processing lines, while enabling continuous production, lack a heat shrink tubing device. This necessitates manual installation of the heat shrink tubing onto the fabric roll, followed by the use of a handheld blower or similar heating device to shrink and secure the tubing. This process is inefficient and prone to errors due to manual operation, affecting the quality of the finished clamps. Therefore, this invention proposes a clamp processing line that automatically completes the heat shrink tubing connection and retraction. Summary of the Invention

[0004] This invention provides a production process for clamps, which achieves automatic fitting and shrinking of heat shrink tubing by adding a heat shrink tubing device to the production line, thus solving the problem that existing clamp processing production lines cannot automatically complete the fitting and shrinking of heat shrink tubing.

Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] In this embodiment, refer to Figures 1-10 The specific implementation of the clamp processing production line includes a base 1 and a conveying device 2. The base 1 is sequentially equipped with a leveling device 3, a punching device 4, a heat shrink tubing device 5, and a bending device 6. The heat shrink tubing device 5 includes an opening part 51, a cutting part 52, a heat shrinking block 53, a clamping claw 54, and a feeding assembly 55. The opening part 51 and the heat shrinking block 53 are slidably installed on the upper end of the base 1. The cutting part 52 is fixedly installed on the base 1. The clamping claw 54 is located on the upper end of the base 1 through a moving assembly 56. The feeding assembly 55 is located on one side of the base 1. The base 1 is provided with a fixing block 11 that cooperates with the heat shrinking block 53. The base 1 is provided with a driving part 12 that cooperates with the opening part 51 and the heat shrinking block 53.

[0012] Through the coordinated operation of the conveying device 2, leveling device 3, punching device 4, heat shrink tubing device 5, and bending device 6, a fully automated processing flow for clamps is achieved from raw material input to finished product output. This significantly improves production efficiency and reduces labor costs. In this embodiment, two sets of heat shrink tubing devices 5 are provided, and the two sets of heat shrink tubing devices 5 are sequentially arranged on the base 1 along the first direction. Each set of heat shrink tubing devices 5 can independently perform heat shrink tubing operation, allowing the simultaneous assembly of two heat shrink tubing sections in one processing operation, thereby improving processing efficiency.

[0013] The feeding assembly 55 includes a rotating disk 551 and a drive motor 552. The rotating disk 551 is rotatably mounted on one side of the base 1 via the drive motor 552, and heat shrink tubing is mounted on the rotating disk 551. Through the cooperation of the rotating disk 551 and the conveying device 2, the heat shrink tubing is conveyed into the production line. When the heat shrink tubing reaches a predetermined length, the moving assembly 56 causes the clamping claw 54 to grip the heat shrink tubing, and the cutting member 52 cuts the heat shrink tubing. Subsequently, driven by the moving assembly 56, the clamping claw 54 moves the cut heat shrink tubing to the opening member 51. The opening member 51 slides via the drive member 12, inserts one end of the heat shrink tubing, and expands it. Then, the conveying device 2 passes the expanded heat shrink tubing through it. When the heat shrink tubing is at a predetermined position on the roll, the opening member 51 releases the heat shrink tubing and slides backward, allowing the heat shrink tubing to be fitted onto the outside of the roll. The heat shrinking block 53 is pushed by the drive component 12 to heat shrink the heat shrink tube and fix it in the designated position on the roll material, thereby completing the installation of the heat shrink tube.

[0014] The movable component 56 includes a fixed frame 561 and a fixed plate 562. The fixed frame 561 is fixedly installed on the base 1 by bolts. The fixed plate 562 is slidably installed on the fixed frame 561 by a guide rod 563. A fixing locking block 564 that cooperates with the guide rod 563 is provided on one side of the fixed plate 562. A slidable connecting plate 565 is provided on the fixed plate 562. A piston cylinder 566 that cooperates with the connecting plate 565 is provided at one end of the fixed plate 562. The clamping claw 54 is fixedly installed on the connecting plate 565. In use, the position of the clamping claw 54 is adjusted by sliding the fixed plate 562. When adjusted to the appropriate position, the fixed plate 562 is locked by the fixing locking block 564. Then, the piston cylinder 566 pushes the connecting plate 565 to slide, thereby driving the clamping claw 54 to perform the operation of clamping or releasing the heat shrink tubing.

[0015] The opening component 51 includes an opening cylinder 511 and two clamps 512 symmetrically arranged at the output end of the opening cylinder 511. The two clamps 512 move or rotate in opposite directions via the opening cylinder 511. Driven by the opening cylinder 511, the clamps 512 open and close. When the clamps 512 open or close, they can open or release one end of the heat shrink tubing, thus facilitating the alignment and fitting of the heat shrink tubing with the roll material. The mating surfaces of the clamps 512 and the heat shrink tubing are provided with anti-slip teeth to ensure that the heat shrink tubing does not slip when clamped, thereby improving clamping stability.

[0016] Suction cups 513 are symmetrically arranged on both sides of the opening 51. The suction cups 513 are slidably mounted on the base 1 via a telescopic cylinder 514. The suction cups 513 are fixedly connected to the piston rod of the telescopic cylinder 514. When the telescopic cylinder 514 operates, the piston rod pushes the suction cups 513 to slide. The suction cups 513 open and close via the telescopic cylinder 514, thus opening the heat shrink tubing and allowing the clamp 512 to be smoothly inserted into it. After the clamp 512 is inserted into the heat shrink tubing, the suction cups 513 release the heat shrink tubing and return to their original position. At this time, the clamp 512 continues to open the heat shrink tubing, ensuring that the heat shrink tubing is completely fitted onto the roll material. The suction cups 513 not only facilitate the opening and fitting of the heat shrink tubing but also improve the accuracy and efficiency of heat shrink tubing installation, making the operation of the entire heat shrink tubing device 5 smoother and more automated.

[0017] The cutting component 52 includes scissors 521 and a drive cylinder 522 for driving the scissors 521 to perform the cutting action. One end of the scissors 521 is provided with a fixing claw 523 that cooperates with the conveying device 2. In use, the drive cylinder 522 pushes the scissors 521 to perform the cutting action. The fixing claw 523 is used to cooperate with the conveying device 2 to keep the heat shrink tubing stable during the cutting process and prevent the heat shrink tubing from shifting or slipping during cutting. A certain gap is left between the fixing claw 523 and the scissors 521 so that the heat shrink tubing leaves a certain length after the scissors 521 cuts, ensuring that the conveying device 2 can smoothly grasp the heat shrink tubing for subsequent processing.

[0018] The conveying device 2 includes a feeding rack 21, a guide roller assembly 22, and several picking claws 23 for cooperating with the heat shrink tubing device 5 and the bending device 6. The feeding rack 21 is located at one end of the base 1, and a rotatable feeding disc 211 is provided on the feeding rack 21. The guide roller assembly 22 is rotatably mounted on the base 1, and the base 1 is provided with a linear module 17 that slides with the picking claws 23. A power element that rotates with the guide roller assembly 22 is provided inside the base 1. Through the cooperation of the feeding disc 211 and the guide roller assembly 22, the roll material is conveyed from the feeding disc 211 into the production line, and the roll material moves along a predetermined path as the guide roller assembly 22 rolls. The linear module 17 pushes the picking claws 23 to slide in a first direction.

[0019] In the heat shrink tubing device 5, the linear module 17 slides the picking claw 23 to grip the heat shrink tubing between the scissors 521 and the fixing claw 523. Then, the fixing claw 523 releases the heat shrink tubing, and the linear module 17 slides the picking claw 23 to pull the heat shrink tubing. When the heat shrink tubing is pulled to a predetermined length, the clamping claw 54 and the fixing claw 523 clamp the heat shrink tubing, and the scissors 521 cut the heat shrink tubing. Then, the moving component 56 pushes the clamping claw 54 to deliver the heat shrink tubing on the clamping claw 54 to a designated position to engage with the opening piece 51, allowing the roll material to pass through. In the bending device 6, the picking claw 23 is used to grip the roll material with the heat shrink tubing attached and pull it to the bending head 63 for bending, thus completing the bending process of the clamp.

[0020] The leveling device 3 includes a rotating frame 31, a straightening plate 32, and several rolling rollers 33. The rotating frame 31 is located at the upper end of the base 1. The straightening plate 32 is rotatably mounted on the rotating frame 31. The several rolling rollers 33 are divided into two rows and are evenly arranged on the base 1 along a first direction. The rolling rollers 33 are connected by a gear set 34. The base 1 is equipped with a rotary motor 13 that cooperates with the gear set 34. The rotating frame 31 is fixedly mounted on the base 1 by bolts. Both ends of the straightening plate 32 are provided with rotating shafts. The straightening plate 32 is rotatably mounted on the rotating frame 31 through the rotating shafts. Adjustment holes are provided through both ends of the straightening plate 32. The rolling rollers 33 are rotatably mounted on the base 1 through bearings. One end of the rolling rollers 33 is connected to the gear set 34. In use, the roll material is passed through the straightening hole, through the straightening plate 32, and inserted between the two rows of rolling rollers 33. The two fixed rollers rotate in opposite directions through the cooperation of the rotary motor 13 and the gear set 34, which drives the roll material to move along a predetermined path. The straightening plate 32 and the rolling rollers 33 are used to level the roll material and keep it flat for subsequent processing operations.

[0021] A return spring 35 is provided at one end of the rolling roller 33. During the movement of the roll material, the return spring 35 ensures that the two rows of rolling rollers 33 always maintain a tight fit. In this way, the return spring 35 applies a continuous and uniform leveling pressure to the roll material, thereby improving the leveling effect of the roll material and meeting the high precision requirements in the roll material processing process.

[0022] The blanking device 4 includes a moving die 41 and a fixed die 42. The moving die 41 and fixed die 42 are each equipped with a matching stamping die 43. The fixed die 42 is fixedly mounted on a base 1, and the moving die 41 is slidably mounted on the base 1. An output component 14, which connects and mates with the moving die 41, is provided on one side of the base 1. Through the interaction between the output component 14 and the moving die 41, the moving die 41 and the stamping die 43 on the fixed die 42 cooperate to complete the blanking process of the coil material. The blanking die can be replaced according to the clamp, thereby completing complex processing such as snapping, creating raised and recessed points, rounding corners, and cutting. This allows for greater diversity in the shape, size, and function of the clamps to meet the needs of different users. The fixed die 42 is equipped with a discharge port to facilitate the discharge of waste material after blanking, preventing waste accumulation from affecting subsequent processing flows. This ensures the processing efficiency of the entire blanking device 4.

[0023] In this embodiment, there are two sets of bending devices 6, which are symmetrically arranged at one end of the base 1. The arrangement of two sets of bending devices 6 allows the roll material to be bent twice simultaneously, thereby improving the processing efficiency of the clamp.

[0024] The bending device 6 includes a sliding frame 61, a sliding plate 62, and a bending head 63. The sliding frame 61 is slidably mounted on one end of the base 1, the sliding plate 62 is slidably mounted on the sliding frame 61, and the bending head 63 is rotatably mounted on one end of the sliding frame 61. Both the base 1 and the sliding frame 61 are provided with a linear guide 64 and a rack 65. The sliding frame 61 and the sliding plate 62 are respectively provided with a slider 66 that cooperates with the linear guide 64 and the rack 65, and a drive gear 67. One end of both the sliding frame 61 and the sliding plate 62 is provided with a gear motor 68 that cooperates with the drive gear 67. The bending head 63 is mounted on one end of the sliding plate 62 via a servo motor 70. The servo motor 70 drives the bending head 63 to rotate, thereby realizing the bending operation of the rolled material.

[0025] The base 1 is also equipped with a positioning claw 15 that cooperates with the bending head 63, and the sliding frame 61 is equipped with a pressing cylinder 69 that cooperates with the positioning claw 15. Through the cooperation of the positioning claw 15 and the pressing cylinder 69, the coil material is accurately positioned and pressed, preventing the coil material from shifting or sliding during the bending process, thereby ensuring the accuracy and precision of the bending. The positioning claw 15 is driven by a reciprocating cylinder 16 and is telescopically mounted on the base 1. When the coil material moves to the predetermined position, the reciprocating cylinder 16 pushes the positioning claw 15 to extend and position the coil material. Then, the pressing cylinder 69 presses the coil material to ensure that the coil material remains stable during the bending process. Subsequently, the sliding frame 61 and the sliding plate 62 slide along the linear guide 64 driven by the gear motor 68, causing the bending head 63 to move to the bending point of the coil material. At this time, the servo motor 70 drives the bending head 63 to rotate, performing the bending operation on the coil material. This forms the initial shape of the clamp.

[0026] A manufacturing process for clamps, using the aforementioned clamp processing line, includes the following steps: Step 1: The roll material is fed to the leveling device 3 for leveling. Step 2: Open one end of the heat shrink tubing through the opening piece 51, and thread the roll material into the heat shrink tubing. Then, the heat shrink pressure block 53 cooperates with the fixing block 11 to shrink and fix the heat shrink tubing onto the roll material. Step 3: Drive the punching device 4 to cut the roll material and then transport the roll material to the bending device 6 for bending.

[0027] Step 4: Weld or join the two ends of the roll material to form a clamp; Furthermore, step 1 also includes: conveying the roll material to the punching device 4 for punching processing.

[0028] Furthermore, it also includes: Step 5, heating the heat shrink tubing to shrink it and make it fit tightly against the clamp surface.

[0029] The beneficial effects of the present invention are as follows: By adding a heat shrink tubing device 5 to the automated production line, the heat shrink tubing can be automatically connected and shrunk without manual operation during the production process of the clamp, thereby improving production efficiency, reducing production costs, reducing errors caused by manual operation, and thus improving the quality of the finished clamp.
