Technical Field

[0001] The utility model relates to the technical field of wire harness terminal crimping, in particular to a device for processing the surplus material of wire harness terminal crimping. Background Technique

[0002] Wire harness terminal crimping is a wire harness connection technology used in electronic or electrical equipment. In this technology, the end of the wire harness is connected to a metal terminal, and then a connection is formed through a crimping operation. Crimping is a cold working process that uses mechanical force to plastically deform the metal terminal to ensure good electrical and mechanical connections with the wire.

[0003] Terminals are used in the loop single matching of wire harnesses, and the terminals rely on copper strips for connection. During crimping production, after the terminal strip is crimped, there is surplus strip material left. The treatment of the surplus strip material has always been a difficult problem to solve. Previous treatment methods have brought many inconveniences. For example, when the terminal strip breaks, the strip debris will fly everywhere, making the working environment messy and inconvenient for waste collection. If the strip is not cut, the surplus strip material will accumulate. The operator also has to spend energy constantly monitoring the strip condition during production and manually cut it after a certain length. Content of the Utility Model

[0018] The following will clearly and completely describe the technical solutions of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Refer to Figure 1-2 , the wire harness terminal crimping waste material processing device includes a workbench 100 and a crimping machine 110 arranged on its top. A guiding member 120 is arranged on the workbench 100, and one end of the guiding member 120 is fixed on the workbench 100 and extends to its bottom; a cutter 140 is fixed at the bottom of the workbench 100, and the output end of the cutter 140 corresponds to the extending end of the guiding member 120.

[0020] The workbench 100 serves as the supporting foundation of the entire device, providing a stable installation platform for the crimping machine 110 and other components. The crimping machine 110 is located on top of the workbench 100 and is used to perform the crimping work of wire harness terminals, ensuring good electrical and mechanical connections between the wire harness and the terminals. The guide 120 is fixed to the workbench 100 and extends to the bottom, and is used to guide and position the terminal strip, ensuring the accurate movement of the strip during the crimping process. The cutter 140 is fixed to the bottom of the workbench 100 and corresponds to the extended end of the guide 120, and is used to cut off the surplus material of the terminal strip in a timely manner after crimping.

[0021] The cutter 140 includes but is not limited to pneumatic, electric, and hydraulic push rods, which drive a fixed cutter through piston movement to achieve the cutting of the surplus material of the discharged terminal strip. The cutter can be a fixed blade or a block structure, designed to be directly connected to the piston or cylinder of the cutter 140 to form a solid cutting interface.

[0022] In some embodiments, the guide 120 is a tubular member, and the end thereof far from being fixed to the workbench 100 is arc-turned to correspond to the front side of the crimping machine 110.

[0023] As a key component of the wire harness terminal crimping surplus material processing device, the guide 120 is designed as a tubular member with a specific shape and structure for precise strip guiding. One end of the guide 120 is designed to be arc-turned, and this design helps to smoothly guide the movement of the terminal strip in front of the crimping machine 110, ensuring the stability and accurate alignment of the strip during the crimping process. The arc-turned end corresponds to the front side of the crimping machine 110, which means that the design and position of the guide 120 are optimized to seamlessly cooperate with the working area of the crimping machine, thereby improving the overall work efficiency.

[0024] The guide 120 is made of high-strength materials such as steel or engineering plastics to ensure durability and reliability during long-term use. The tubular design of the guide 120 facilitates cleaning and maintenance, and is also easy to quickly replace if there is wear or damage during use. The design of the tubular member allows a certain degree of bending and deformation to adapt to terminal strips of different sizes and shapes, increasing the adaptability and flexibility of the device. The design of the guide 120 also takes into account the safety of the operator to ensure that the movement of the strip will not cause harm to the operator during high-speed or high-pressure crimping operations.

[0025] In some embodiments, a discharge member 130 is provided at the bottom of the workbench 100, and a discharge channel 131 is provided inside the discharge member 130.

[0026] The discharging member 130, as part of the wire harness terminal crimping waste material processing device, is responsible for collecting and guiding the waste material of the cut terminal tape, preventing the waste material from scattering chaotically, and keeping the working environment clean. The discharging channel 131 designed inside the discharging member 130 is a dedicated channel for orderly transporting the waste material of the cut terminal tape from the working area to the collection area. The design of the discharging member 130 usually matches the bottom structure of the workbench 100 to ensure the smooth and efficient discharging process.

[0027] The discharging member 130 is made of durable and easy-to-clean materials such as metal or high-performance plastics for long-term use and reduced maintenance. The design of the discharging channel 131 can include specific curves and angles to optimize the flow characteristics of the tape waste material and reduce the risk of blockage and accumulation.

[0028] In some embodiments, a fixing member 132 protruding upward is provided on one side of the discharging member 130. The top of the fixing member 132 is fixed to the front side of the bottom of the workbench 100, and the bottom of the fixing member 132 is fixed to the end side of the discharging member 130.

[0029] The design of the fixing member 132 is used to ensure the stability and correct position of the discharging member 130 on the workbench 100. Its top is fixed to the front side of the bottom of the workbench 100, and its bottom is fixed to the end side of the discharging member 130, forming a stable support structure. Through the connection of the fixing member 132 with the workbench 100 and the discharging member 130, the stability of the entire discharging system is enhanced, preventing displacement or vibration during operation. The position design of the fixing member 132 ensures the precise docking of the discharging channel 131 with the output position of the crimping machine 110, thereby ensuring that the waste material can smoothly enter the discharging channel and be effectively collected.

[0030] The fixing member 132 can be fixed to the workbench 100 and the discharging member 130 by mechanical means such as bolts, welding, or snap-fitting to adapt to different installation requirements and facilitate maintenance. The fixing member 132 and the discharging member 130 adopt a modular design for easy quick replacement or upgrade to adapt to different production requirements. The design of the fixing member 132 includes edge chamfers or protective covers to prevent operators from accidentally touching sharp edges. The fixing member 132 and the discharging member 130 are made of durable materials to resist wear and impact during daily use.

[0031] In some embodiments, the fixing member 132 has a C-shaped structure, and the inner side of the C-shaped structure surrounds the outer part of the extended end of the guiding member 120.

[0032] The C-shaped structure design of the fixing member 132 enables it to surround and fix the extension end of the guiding member 120, providing better support and positioning effects. The inner side of the C-shaped structure surrounds the extension end of the guiding member 120, which helps to maintain the accurate position of the guiding member and ensure the stability of the guiding member during the entire crimping and discharging processes. The C-shaped structure provides additional structural strength, capable of withstanding the forces generated during the crimping and discharging processes, reducing the risk of component deformation or displacement. The C-shaped structure of the fixing member also plays a protective role, preventing the guiding member 120 from being accidentally impacted or externally interfered with.
