Description

Technical Field

[0001] This utility model relates to the field of medical neutral electrode assembly equipment, specifically to a neutral electrode needle assembly and pressing device. Background Technology

[0002] With the rapid development of the medical device industry, medical device plugs, as indispensable connecting components in medical equipment, directly affect the performance and safety of these devices through their assembly quality and efficiency. Currently, the assembly of medical device plugs mainly involves multiple processes, including bottom shell loading, pin assembly, wire crimping, top shell assembly, and welding.

[0003] Traditional plug assembly relies primarily on manual operation, requiring workers to manually complete each assembly step. This method is not only inefficient but also prone to inconsistent assembly quality due to human error, failing to meet the high reliability requirements of modern medical devices. While automation technology has led to the application of automated equipment in plug assembly, existing technologies still have limitations.

[0004] In the prior art, CN114571211A discloses a device for assembling pins and springs. This device includes a conveying mechanism, a pin feeding mechanism, a spring feeding mechanism, and a pressing mechanism, which can realize the automatic assembly of pins and springs. However, this device only focuses on the assembly of pins and springs and cannot complete all the processes of plug assembly, especially lacking key steps such as wire crimping and soldering.

[0005] CN108890260B discloses a magnetic core assembly device, which includes a discharge vibratory feeder, a material transfer assembly, a wire insertion conveying assembly, and a pressing assembly, thereby improving assembly efficiency through automated operation. However, this device is mainly designed for magnetic core assembly, and its structural design is not suitable for the multi-process assembly requirements of plugs, especially failing to meet the requirements for precise alignment and pressing in plug assembly.

[0006] CN113690102B provides an automatic terminal insertion device, including an insertion workbench, a terminal feeding mechanism, a crimping mechanism, and an assembly and testing mechanism. Although this device achieves automatic insertion and crimping of terminals, it lacks support for wire end crimping and soldering processes, and cannot complete the entire plug assembly process.

[0007] CN113977225A discloses an automatic assembly device, including a conveying mechanism, a feeding mechanism, a pressing mechanism, and a discharging mechanism, which can realize the automatic feeding, pressing, and discharging of workpieces. However, the structure of this device is relatively simple and it is difficult to adapt to the precise positioning and combination requirements of various components in plug assembly.

[0008] CN221041900U describes a two-core wire terminal box assembly device, including a fixture, a conveyor line, a feeding unit, and an ultrasonic welding unit, which can assemble terminals and wire boxes. However, this device is mainly designed for wire box assembly, and its fixture design and station layout are not suitable for the special requirements of plug assembly.

[0009] In summary, existing technologies suffer from the following problems: Firstly, current plug assembly equipment often only completes a single or a few processes, lacking integrated, fully automated assembly capabilities, leading to complex production lines and difficulties in coordinating between equipment. Secondly, the fixture design and conveying mechanisms of existing equipment struggle to meet the precise positioning and efficient conveying requirements of various components in plug assembly, affecting assembly accuracy and efficiency. Furthermore, existing equipment generally lacks specialized designs for special processes such as wire crimping and ultrasonic welding, making it difficult to guarantee the quality and reliability of plug assembly. Therefore, there is an urgent need to develop an automated plug assembly and crimping equipment that integrates all processes, including bottom shell feeding, pin assembly, wire crimping, top shell assembly, and welding, to improve production efficiency and product quality.

[0029] During plug assembly and pressing: First, the bottom rubber shell is placed in the bottom rubber shell feeding mechanism 3. The feeding function is used to transfer the bottom rubber shell to the bottom rubber shell clamping mechanism 4. The bottom rubber shell clamping mechanism 4 clamps and transfers the bottom rubber shell to the fixture 12 on the conveying mechanism 2. The conveying mechanism 2 then transfers the fixture 12 carrying the bottom rubber shell to the clamping and pressing mechanism 6. At the same time, the needle material feeding mechanism 5 transfers the needle material to the clamping and pressing mechanism 6. The clamping and pressing mechanism 6 transfers the needle material to the corresponding bottom rubber shell for assembly and pre-pressing. After assembly, the conveying mechanism 2 continues to transfer the fixture 12 to the wire pressing mechanism 7. The wire end is then manually placed... At the upper wire pressing mechanism 7, the wire ends are pressed and assembled into the bottom plastic shell. Then, the conveying mechanism 2 transfers the assembled wire end fixture 12 to the upper plastic shell suction mechanism 9. The upper plastic shell feeding mechanism 8 transfers the upper plastic shell to the upper plastic shell suction mechanism 9. The upper plastic shell suction mechanism 9 then clamps and transfers the upper plastic shell to the fixture 12 to combine with the bottom plastic shell inside the fixture 12.
