Description

Technical Field

[0001] The utility model belongs to the technical field of wire material processing, and more specifically, particularly relates to an automatic three-core wire terminal-punching and heat-shrinking integrated machine. Background Art

[0002] Wire crimping terminals refer to the process of connecting the bare wire to the terminal. Wire crimping terminals can firmly connect the bare metal conductor to the terminal to ensure the smooth conduction of current, thereby realizing the conductive function of the circuit. At the same time, the terminal can effectively protect the metal conductor of the wire, prevent damage to the conductor by the external environment, and improve the safety and reliability of the connection. The quality of wire crimping terminals will directly affect the reliability and electrical performance of the connection. The quality of each step needs to be strictly controlled during the production process to ensure the stability and reliability of the terminal connection.

[0003] There are two existing methods for crimping wire terminals. One is manual crimping, which involves manually cutting the wires, and then manually crimping cold-pressed terminals or semi-automatically crimping sideband terminals. However, the traditional manual crimping method is prone to causing barbs on the copper wires of the wires when inserting the terminals, resulting in an increase in defective products. In addition, during use, due to the thick insulation layer of the cold-pressed terminals, when they are superimposed on the wiring terminals, they are prone to fall off and are not aesthetically pleasing. At the same time, the manual crimping process involves many steps, which increases production and time costs. The other method is to use a single-function automatic crimping machine, which improves work efficiency and reduces labor costs. However, a single-function automatic crimping machine can only crimp terminals of a specified type, and changing the terminal type requires a large number of workpieces to be replaced, with fewer options. In addition, the terminal feeding mode is single and cannot meet different needs. At the same time, the step of inserting the heat shrink tube is at the end, which is easily blocked by the terminal and causes inadequate puncture, thereby affecting the efficiency and quality of subsequent processes.

[0017] 1. The device can realize the processing operation of wire crimping terminals through the sleeve assembly and the crimping end assembly set on the workbench, reducing the two existing production processes and effectively simplifying the entire production process. At the same time, the cumbersome processes are reduced, and workers no longer need to perform heavy labor for a long time, which reduces the work, not only helps to improve the job satisfaction of employees, reduce fatigue and occupational injuries, but also improves production efficiency and reduces the labor intensity of workers. At the same time, the device adopts cylinder wire clamping and wire feeding, which effectively reduces the production risk factor; and a protective cover is set on the workbench, the protective cover is connected to the workbench to form a protective cavity, and the first clamping assembly and the second clamping assembly are included in the protective cavity, providing a certain safety guarantee for the operator.

[0018] 2. The terminal crimping assembly is equipped with a terminal machine and a terminal crimping mechanism. Through their mutual cooperation and coordinated operation, the precise installation and stable compression of the wire terminal are realized. When the terminal is pressed, the force can be kept uniform and consistent, effectively avoiding the occurrence of uneven pressure on the terminal. Because if the terminal is pressed unevenly, it may cause a series of problems, such as the terminal falling off. And this uniform pressure not only ensures that the connection between the terminal and the wire is firm and reliable, but also improves the stability and reliability of the entire crimping process. In addition, the uniform pressure also helps to extend the service life of the terminal and the wire, reduce the risk of failure and damage, and make the crimping operation more efficient, which can improve production efficiency and reduce production costs. At the same time, through the coordinated operation of the terminal machine and the terminal crimping mechanism, the terminal can be accurately set on the wire, effectively avoiding the problem of the terminal generating barbs on the copper wire of the wire during the setting process. Not only does it ensure the combination of the terminal and the wire, but it also ensures the stability and reliability of the connection. The product can maintain good performance during use and reduce the risk of failure and damage. Moreover, the problem of barbs on the copper wire is avoided, further improving the quality of the product.

[0019] 3. A feeding belt collection wheel is provided on one side of the workbench, so that the terminal feeding belt can be smoothly wound on the feeding belt collection wheel. By clamping one end of the terminal feeding belt on the terminal crimping mechanism, the feeding function of the transverse mold terminal is successfully realized. The setting of the feeding belt collection wheel makes the storage and arrangement of the terminal feeding belt more convenient and orderly, avoiding the confusion and winding of the feeding belt. One end of the feeding belt clamped on the terminal crimping mechanism can ensure that the terminal accurately enters the crimping process, improving the accuracy and stability of the feeding. At the same time, the device first accurately and stably sleeves the heat shrink tube on the wire through the sleeve assembly, laying a good foundation for subsequent processing operations. Then the terminal crimping work is performed through the crimping end assembly. Sleeving the heat shrink tube first can effectively avoid the terminal from hindering the sleeve of the heat shrink tube, thereby preventing the heat shrink tube from being inadequately sleeved. It ensures that the heat shrink tube can completely cover the wire and achieve the best protection effect. This sequence also improves the working efficiency and processing quality of the entire device. Applying the heat shrink tubing first can reduce the failure of application due to inaccurate terminal position or other factors, thereby reducing the scrap rate. BRIEF DESCRIPTION OF THE DRAWINGS

The wire 61 is respectively clamped in the first clamping assembly and the second clamping assembly, and the first clamping assembly and the second clamping assembly are used to fix the wire 61, so that the wire 61 is conveniently placed in the sleeve assembly and the crimping end assembly for corresponding processing. At the same time, a protective cover 12 is arranged on the workbench 11. The protective cover 12 is tightly connected to the workbench 11 to form a protective cavity. The first clamping assembly and the second clamping assembly are both located within the range of this protective cavity. It provides a certain safety guarantee for the operator. It can reduce the chance of manual direct contact with the wire 61 and the tool, and reduce the risk of work-related injuries. A control panel 13 is also provided on the workbench 11. This control panel 13 is responsible for controlling and adjusting the operation of each component to ensure the smoothness and accuracy of the entire workflow. It not only reflects a high degree of functionality and practicality, but also fully considers the safety and convenience of operation. The reasonable layout of the sleeve assembly and the crimping end assembly provides strong support for the processing of the wire 61. The setting of the clamping assembly ensures the stable clamping of the wire 61, which helps to improve work efficiency and quality.

[0035] like Figures 2 to 5 As shown, the sleeve assembly includes a positioning seat 201 and a positioning block 202, and the positioning seat 201 is firmly mounted on the workbench 11. A positioning slide rail 203 is arranged on the positioning seat 201, which provides strong support for the precise operation of the entire assembly. A positioning slide groove 204 is provided on the bottom surface of the positioning block 202, and the positioning slide rail 203 can be clamped in the positioning slide groove 204. A sliding connection is formed between the positioning block 202 and the positioning seat 201, which provides a solid foundation for subsequent operations. At one end of the positioning seat 201, a positioning cylinder 205 is specially arranged. The pneumatic rod of the positioning cylinder 205 is tightly connected to the positioning seat 201, which ensures that the cylinder can play a role stably. The position of the positioning block 202 can be controlled by the positioning cylinder 205, and the positioning block 202 can be adjusted according to the use requirements to achieve the fixation of different lengths of the wire 61. The wire 61 is clamped in the first clamping assembly, and one end thereof is in close contact with the positioning block 202. This enables manual labor to install the wire 61 quickly and accurately, and also provides convenience for subsequent processing and operation.

[0036] The sleeve assembly also includes a storage rack 206 and a sleeve mechanism 207. The heat shrink tube is placed on the storage rack 206 in a winding form, and a support rack 208 is provided on the workbench 11. One end of the heat shrink tube passes through the support rack 208 and is clamped in the sleeve mechanism 207. At the same time, one end of the wire 61 can be smoothly inserted into the heat shrink tube. Two groups of cutting cylinders 209 are configured on the sleeve mechanism 207, and a cutting tool 210 is installed at one end of the cutting cylinder 209. In terms of specific positional relationship, the wire 61 is between the two groups of cutting tools 210, and the two groups of cutting tools 210 can come into contact with the heat shrink tube. The existence of the storage rack 206 makes the storage and arrangement of the heat shrink tube more convenient and orderly, avoiding confusion and loss. The setting of the support rack 208 provides strong support for the positioning and fixation of the heat shrink tube, ensuring the accuracy and stability of its position. The cutting cylinder 209 and the cutting tool 210 thereon make the cutting operation of the heat shrink tube more accurate and efficient, and can cut the length of the heat shrink tube in and out according to the set parameters, and jointly complete the processing of the heat shrink tube and the processing of the wire 61. It can improve work efficiency, reduce errors and mistakes, ensure product quality and stability, and avoid accidental injuries during operation.

[0037] A wire stripping mechanism 211 is also provided on one side of the sleeve mechanism 207. Two sets of wire stripping cutters 212 are provided on the wire stripping mechanism 211. The two sets of wire stripping cutters 212 are slidably connected to the wire stripping mechanism 211 through the wire stripping slide rail 213. A wire stripping screw rod 214 is also provided in the wire stripping mechanism 211. The wire stripping cutter 212 is sleeved on the wire stripping screw rod 214, and a wire stripping motor 215 is specially provided at one end of the wire stripping screw rod 214. The wire stripping motor 215 drives the wire stripping screw rod 214 to rotate, which can control the distance between the two sets of wire stripping cutters 212 and can adapt to different wire 61 sizes and stripping requirements. The wire 61 is located exactly between the two sets of wire stripping cutters 212. In addition, a fixing member 216 is specially provided on the other side of the wire stripping mechanism 211, and the wire 61 can be easily clamped between the fixing members 216. The two sets of wire stripping cutters 212 can be used to strip the insulation layer on the wire 61 , so as to facilitate the subsequent crimping of the terminal of the wire 61 .

[0038] like Figure 2 , 6As shown in , 7, the terminal crimping assembly includes a terminal machine 31 and a terminal crimping mechanism 32. The terminal crimping mechanism 32 is located below the terminal machine 31. A feed belt collecting wheel 33 is provided on one side of the workbench 11. The terminal feed belt is neatly arranged on the feed belt collecting wheel 33 in a winding form, and one end thereof is firmly clamped on the terminal crimping mechanism 32. The wire 61 is located between the terminal machine 31 and the terminal crimping mechanism 32, and the terminal can be accurately and correctly sleeved on one end of the wire 61. As one of the core parts of the terminal crimping assembly, the terminal machine 31 has precise processing and control capabilities, which can ensure the processing quality and stability of the terminal. The terminal crimping mechanism 32 is responsible for reliably crimping the terminal and the wire 61 to ensure good electrical connection performance. The setting of the feed belt collecting wheel 33 makes the storage and supply of the terminal feed belt more convenient and efficient. It can effectively keep the feeding belt neat and orderly, avoid confusion and entanglement, and ensure that the terminal is accurately set on one end of the wire 61, thereby improving the accuracy and efficiency of assembly. The terminal assembly can meet various different needs and provide a strong guarantee for the smooth operation of the production line.

[0039] The pressure end assembly also includes a pull-back mechanism 34, on which a first pneumatic clamp 35 is arranged, and the wire 61 can be firmly clamped on the first pneumatic clamp 35, providing additional fixation and support for the wire 61, ensuring the stability of the wire 61 during operation. At the same time, a second pneumatic clamp 36 is also arranged on the pull-back mechanism 34, and one end of the wire 61 is clamped on the second pneumatic clamp 36, and the second pneumatic clamp 36 is connected to the pull-back mechanism 34 in a sliding manner. A pull-back cylinder 37 is also installed on the pull-back mechanism 34, and the pneumatic rod of the pull-back cylinder 37 is directly connected to the second pneumatic clamp 36. The second pneumatic clamp 36 contacts the heat shrink tube on the wire 61, and the heat shrink tube can be pulled to a specified position by the drive of the pull-back cylinder 37, and the heat shrink tube covers the connection between the wire 61 and the terminal.

[0040] A hot air shrinking mechanism 38 is provided on one side of the pull-back mechanism 34. The hot air shrinking mechanism 38 can generate a uniformly distributed hot air flow. The uniform hot air can ensure that the heat shrink tube is evenly heated during the shrinking process, thereby avoiding local overheating or overcooling. It helps to improve the shrinking quality of the heat shrink tube, so that it can shrink evenly and wrap tightly around the wire 61, providing good insulation and protection. After pulling the heat shrink tube back to the specified position, place the heat shrink tube at one end of the wire 61 inside the hot air shrinking mechanism 38, so that the heat shrink tube can be better attached to the wire 61, which also helps to improve the accuracy and efficiency of the operation and reduce errors and waste.

[0041] like Figure 2 , 8As shown, the first clamping assembly includes a first clamping frame 41, a first slide rail 42 is arranged on the workbench 11, and the first clamping frame 41 is clamped inside the first slide rail 42, providing a stable foundation for the clamping operation. A first screw rod 43 is also installed inside the first slide rail 42, and the first screw rod 43 runs through the first clamping frame 41.

The wire 61 is clamped between the upper clamping block 47 and the lower clamping block 45, which is convenient for moving the wire 61 between the sleeve assemblies and sleeve the heat shrink tube on the wire 61.

[0042] like Figure 2 , 9 As shown in Figure 10, the second clamping assembly includes a second clamping frame 51, a second slide rail 52 is arranged on the workbench 11, and a sliding member 53 is arranged at the bottom of the second clamping frame 51. The second slide rail 52 can be easily stuck in the sliding member 53, so as to realize the sliding connection between the second clamping frame 51 and the second slide rail 52. Two groups of connecting plates 14 are arranged on the bottom surface of the workbench 11. A second screw rod 15 is arranged between the two groups of connecting plates 14. A sliding block 54 is arranged at the bottom of the second clamping frame 51, and the sliding block 54 is sleeved on the second screw rod 15. This design enables a sliding connection to be established between the second clamping frame 51 and the second screw rod 15. A powerful and stable second motor 16 is installed at one end of the second screw rod 15, and the second motor 16 drives the second screw rod 15 to rotate, so that the second clamping frame 51 can move along the second slide rail 52. The sliding connection between the second clamping frame 51 and the second slide rail 52 provides a high degree of flexibility for the clamping operation. The position can be adjusted according to work requirements to ensure the accuracy and efficiency of clamping.

[0043] The second clamping frame 51 is provided with an upper clamping claw 55 and a lower clamping claw 56, and racks 57 are provided on the corresponding surfaces of the upper clamping claw 55 and the lower clamping claw 56. A gear 58 is provided between the upper clamping claw 55 and the lower clamping claw 56. The gear 58 is respectively engaged with the two sets of racks 57, which provides a reliable guarantee for the clamping operation and constructs a transmission system. A rotatable connection is established between the gear 58 and the second clamping frame 51, so that the gear 58 can operate flexibly. A lifting cylinder 59 is also specially provided on the second clamping frame 51. The pneumatic rod of the lifting cylinder 59 is tightly connected with the lower clamping claw 56. The lower clamping claw 56 is driven to move by the telescopic movement of the lifting cylinder 59, so that the gear 58 can adjust the distance between the upper clamping claw 55 and the lower clamping claw 56, so as to fix the wire 61, so that the wire 61 can move between the pressing end components, and the pressing end operation of the wire 61 is completed.

[0044] The specific usage and function of this embodiment are as follows:

[0045] When in use, the wire 61 to be processed is clamped in the first clamping assembly, and the wire 61 processed by the sleeve assembly is clamped in the second clamping assembly to ensure that the wire 61 is firmly clamped. As needed, the positions of the first clamping assembly and the second clamping assembly are adjusted for easy operation.

[0046] In the first cycle, the heat shrink tube is wound on the storage rack 206, and one end of the heat shrink tube is passed through the support rack 208 and clamped in the sleeve mechanism 207. The sleeve assembly is started, and the heat shrink tube is sleeved on the wire 61 through the sliding connection between the positioning seat 201 and the positioning block 202. If a wire stripping operation is required, the wire 61 is placed between the two sets of wire stripping cutters 212 of the wire stripping mechanism 211. The wire stripping motor 215 is started, and the distance between the two sets of wire stripping cutters 212 is controlled by the rotation of the wire stripping screw 214 to adapt to different wire 61 sizes and stripping requirements. The wire stripping cutter 212 will automatically strip the insulation layer on the wire 61.

[0047] In the second cycle, the wire 61 with the heat shrink tube is placed between the terminal machine 31 and the terminal crimping mechanism 32 to ensure that the terminal can be accurately mounted on one end of the wire 61. Start the terminal crimping assembly, and clamp one end of the terminal feed belt on the terminal crimping mechanism 32 through the feed belt collection wheel 33. The terminal machine 31 will perform precise processing and control on the terminal, and the terminal crimping mechanism 32 will reliably crimp the terminal and the wire 61 to ensure good electrical connection performance. A first pneumatic clamp 35 and a second pneumatic clamp 36 are set on the pullback mechanism 34, and one end of the heat shrink tube is clamped on the second pneumatic clamp 36. Start the pullback mechanism 34, and pull the heat shrink tube to the specified position through the drive of the pullback cylinder 37, so that it covers the connection between the wire 61 and the terminal. The pulled back heat shrink tube is placed inside the hot air shrinking mechanism 38, and the hot air shrinking mechanism 38 is started to generate a uniformly distributed hot air flow. The hot air flow will evenly heat the heat shrink tube, causing it to shrink and tightly wrap around the wire 61, providing good insulation and protection. The second motor 16 is started, and the second screw rod 15 is driven by the second motor 16 to rotate, so that the second clamping frame 51 can move along the second slide rail 52. The sliding connection of the second clamping frame 51 provides a high degree of flexibility for the clamping operation, and the position can be adjusted according to work requirements to ensure the accuracy and efficiency of clamping.

[0048] The lower claw 56 is moved by the extension and retraction of the lifting cylinder 59, and the position of the gear 58 is adjusted so that the distance between the upper claw 55 and the lower claw 56 is suitable for the size of the wire 61. Then, the upper clamping block 47 is clamped downward by the fixing cylinder 46 to fix the wire 61 between the upper claw 55 and the lower claw 56 to ensure that the wire 61 will not loosen when moving between the crimping end assemblies. Start the crimping end assembly, the terminal machine 31 will perform precise processing and control on the terminal, and the terminal crimping mechanism 32 will reliably crimp the terminal and the wire 61 to ensure good electrical connection performance. During the crimping process, pay attention to the crimping quality to ensure that the connection between the terminal and the wire 61 is firm and reliable.

[0049] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
