Description

Technical Field

[0001] This utility model relates to the field of terminal crimping machine technology, specifically to an intelligent double-head crimping auxiliary terminal crimping machine. Background Technology

[0002] Terminal crimping is a key process in the field of wire connection. It refers to the operation of tightly bonding metal terminals to wire conductors through external force to form a stable electrical and mechanical connection. It is widely used in automotive wiring harnesses, electronic equipment, power engineering and other fields. In these applications, the connection quality between wires and terminals directly determines the stability of circuit continuity and the safety of equipment operation. For example, if the terminal connection in an automotive wiring harness is loose, it may cause malfunctions in the vehicle's electronic system; poor terminal connections in electronic equipment can cause signal transmission interference. As the industry's requirements for product reliability increase and production scale expands, efficient and precise terminal crimping technology is needed to ensure connection quality and meet the needs of mass production. Traditional terminal crimping technology relies heavily on manual or semi-automatic equipment, which has its drawbacks. Manual crimping requires operators to apply pressure directly, which is not only labor-intensive but also prone to inconsistent crimping depth due to uneven pressure control, resulting in large fluctuations in the bonding force between the terminal and the wire, and some connections are at risk of falling off. While semi-automatic equipment reduces manpower, it is mostly a single-head crimping structure, which can only process one terminal at a time. Furthermore, it lacks precise guidance and limiting during the crimping process, making the terminal positioning prone to deviation and resulting in a high defect rate. These defects not only reduce production efficiency and increase raw material waste but also affect the quality of downstream products due to poor connections, creating safety hazards for subsequent use. To address these issues, we propose an intelligent dual-head crimping auxiliary terminal machine. Utility Model Content

[0025] Working Principle: First, the crimping auxiliary component 2 is installed on the inner left side of the terminal crimping machine body 1. It is the key execution unit for realizing terminal crimping. The crimping auxiliary component 2 is further composed of a crimping base 3, an auxiliary base 4, a power unit, and a crimping assembly. The auxiliary base 4 is fixed to the top of the crimping base 3, forming a stable installation and operation platform. The power unit is installed inside the crimping base 3 and consists of an electric cylinder 5, a guide 6, and a slide rail shaft 10. A cylinder groove 11 is pre-cut inside the crimping base 3, and the electric cylinder 5 is installed in the cylinder groove 11 with its piston shaft facing upwards. The top of the piston shaft passes through the top of the crimping base 3 and extends into the interior of the upper auxiliary base 4. The auxiliary base 4 has a corresponding auxiliary storage groove 12 inside. The piston of the electric cylinder 5... The top of the shaft is connected to the guide member 6 located in the auxiliary storage groove 12. Simultaneously, slide rail shafts 10 are fixedly installed on the inner sides of both ends of the guide member 6. When the equipment starts the pressing program, the electric cylinder 5 first receives the control signal and starts. Its piston shaft pushes the guide member 6 upwards in the vertical direction. Under the limiting action of the auxiliary storage groove 12, the guide member 6 can only maintain a stable vertical lifting motion, avoiding deviation and ensuring the accuracy of subsequent power transmission. The slide rail shaft 10 moves synchronously with the guide member 6, serving as the key to connecting the power unit and the pressing unit. The pressing unit converts power into pressing action and is installed inside the auxiliary base 4, consisting of a pressing rotating member 7, a first pressing joint 8, and a second pressing joint 9. Rotating shafts 1 are pre-installed at both ends inside the auxiliary storage groove 12. 3. The end of the pressing rotating component 7 is provided with a rotating hole 14. By fitting the rotating shaft 13 into the rotating hole 14, the pressing rotating component 7 can rotate flexibly around the rotating shaft 13. At the same time, the end of the pressing rotating component 7 is also provided with a slide rail groove 15, the end of which extends into the inner sides of both ends of the guide component 6, and the slide rail shaft 10 is exactly placed inside the slide rail groove 15, forming a tangential fit. When the guide component 6 moves upward under the push of the electric cylinder 5, the slide rail shaft 10 will slide along the slide rail groove 15, generating an upward thrust on the pressing rotating component 7, causing the pressing rotating component 7 to rotate around the rotating shaft 13. Since the pressing rotating components 7 at both ends of the auxiliary base 4 are symmetrically distributed, they will rotate inward synchronously, and the top of the pressing rotating component 7 extends out of the top of the auxiliary base 4. Furthermore, the tops of the two end-to-end pressing rotating parts 7 are respectively fixed with bolts to the first pressing head 8 and the second pressing head 9. Both move inward synchronously with the rotation of the pressing rotating part 7. The first pressing head 8 and the second pressing head 9 have an anti-symmetrical structure, with multiple equidistantly distributed engaging teeth 16 at their front ends, and their front ends are opposite each other. When they move inward, the engaging teeth 16 engage with each other, and a gap is formed at the connection point. The wire terminal to be pressed is precisely clamped within this gap. As the pressing rotating part 7 continues to rotate, the clamping force of the first pressing head 8 and the second pressing head 9 on the wire terminal gradually increases, ultimately completing the crimping operation of the wire terminal and achieving a stable connection between the wire and the terminal. After the crimping operation is completed, the electric cylinder 5 receives a reset signal, and the piston axially retracts downward.The guide member 6 moves downwards synchronously, and the slide rail shaft 10 slides in the opposite direction along the slide rail groove 15, generating a downward pulling force on the crimping rotating member 7. This causes the crimping rotating member 7 to rotate in the opposite direction around the rotating shaft 13, thereby causing the first crimping connector 8 and the second crimping connector 9 to separate outwards, releasing the crimped wire terminal. At this point, the equipment returns to its initial state and can wait for the next crimping command to enter the next work cycle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
