Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to an automatic alignment and assembly device for a single fuse and a terminal cap. Background Technology

[0002] A single-cell fuse is an overcurrent protection component used in electrical equipment such as new energy, photovoltaic, and industrial electrical control systems. It contains a fuse wire; when the current exceeds a set value, the fuse wire melts, thus cutting off the circuit and providing protection. The "semi-finished product" mentioned in the document refers to the fuse body before the terminal encapsulation is completed. Terminal caps are metal / conductive cap-shaped parts installed at both ends of the fuse, used for connection to the circuit, and also serve to fix, protect, and conduct electricity. They need to be precisely pressed into the axial position of the fuse body to ensure electrical performance and mechanical strength.

[0003] Both individual fuses and terminal caps are small parts, requiring strict coaxiality and positional accuracy after press-fitting. Even slight misalignment can cause the terminal cap to be warped or eccentric, resulting in poor contact or scrap. Furthermore, the parts are lightweight and symmetrical, making them prone to slippage and offset during positioning. Therefore, achieving stable and precise alignment in high-speed automated production is a key challenge of this process.

[0004] The assembly of existing single fuses and terminal caps mainly relies on manual operation, which results in low production efficiency and is prone to excessive positioning errors due to visual fatigue, posing significant safety risks and low product yield. Utility Model Content

[0032] In one possible implementation, the central axes of the stop hole 204 and the lower mold cavity 202 coincide with the central axis of the lower mold 201. The central axes of the upper mold hole 206 and the dome 102 coincide with the central axis of the upper mold 205.

[0033] It should be noted that the central axis of the stop hole 204 coincides with the central axis of the lower mold cavity 202, and the central axis of the upper mold hole 206 and the dome 102 also coincides with the central axis of their respective molds. This coaxial design ensures that the upper and lower molds and the workpiece always maintain precise alignment, thereby significantly improving the stability and accuracy of the press-fitting process.

[0034] In one possible implementation, the central axes of the lower mold 201 and the upper mold 205 coincide.

[0035] Understandably, the central axes of the lower mold 201 and the upper mold 205 coincide.

[0036] In one possible implementation, the first linear bearing 303 is fixedly connected to the first upper connecting block 104. The second linear bearing 304 is fixedly connected to the second upper connecting block 106.

[0037] It should be noted that the first linear bearing 303 is fixedly connected to the first upper connecting block 104, and the second linear bearing 304 is fixedly connected to the second upper connecting block 106. This ensures that the upper mold can achieve smooth and precise linear movement under the guidance of the guide post, thereby improving the stability and accuracy of the pressing process.

[0038] In one possible implementation, the first guide post 301 is fixedly connected to the first lower connecting block 103. The second guide post 302 is fixedly connected to the second lower connecting block 105.

[0039] It should be noted that the first guide post 301 is fixedly connected to the first lower connecting block 103, and the second guide post 302 is fixedly connected to the second lower connecting block 105. This forms a stable guide support structure, ensuring the straightness and coaxiality of the upper mold when it moves along the guide post, thereby improving the accuracy and reliability of the assembly.

[0040] In one possible implementation, the lower vent 2011 and the upper vent 2051 are located on the same side.

[0041] It is understandable that the lower vent 2011 and the upper vent 2051 are located on the same side.

[0043] Specifically, the pneumatic accessory 400 consists of a first air pipe connector 401, a second air pipe connector 402, an air pipe 403, and a one-to-two air nozzle 404. The first air pipe connector 401 is connected to the upper vent 2051, and the second air pipe connector 402 is connected to the lower vent 2011. This structure enables the upper and lower molds to generate negative pressure adsorption simultaneously, ensuring the synchronous and accurate positioning of the terminal cap and the fuse semi-finished product, thereby improving assembly efficiency and stability.

[0044] In one possible implementation, it also includes: a plurality of bolts 108.

[0045] Bolt 108 is used to connect components that have a fixed connection method.

[0046] Understandably, multiple bolts 108 are used to securely connect the various components that have a fixed connection relationship. This design not only improves the overall structural stability and vibration resistance of the device, but also facilitates disassembly, maintenance and component replacement in the later stage, thereby ensuring the long-term reliable operation of the equipment.

[0047] The specific working process of the entire device is as follows: First, the terminal cap is placed face down into the upper mold hole. Then, the semi-finished individual fuse is placed into the lower mold cavity and the stop block hole. Negative pressure airflow passes through and positions the semi-finished individual fuse and the terminal cap respectively. The upper connecting block and the upper mold, carrying the terminal cap, move downward along the guide post to press the terminal cap onto the semi-finished individual fuse. The worker removes the product with the outer cap pressed and continues feeding materials for production.

[0048] Furthermore, this precision assembly device utilizes the high-precision guiding properties of linear bearings and guide pillars to effectively solve the problem of product misalignment, reducing manual selection and scrap due to misalignment, and greatly improving product quality and production efficiency. Simultaneously, by changing the mold, it can be used for pressing outer caps of single fuses in multiple product models (10x38, 14x51, 22x58), facilitating production debugging and saving costs.

[0049] In practical applications, this automatic alignment and assembly device utilizes a coaxial design of the lower mold cavity, upper mold hole, stop hole, and dome, combined with high-precision guidance from double guide pillars and linear bearings. This ensures strict coaxial positioning of the terminal cap and fuse semi-finished product during downward pressure. Simultaneously, pneumatic accessories generate negative pressure through upper and lower vents, achieving stable workpiece fixation and preventing errors caused by slippage or offset. Its advantages include significantly reducing errors and visual fatigue associated with manual alignment, improving assembly accuracy and consistency. It boasts a high degree of automation, reducing manual labor intensity and the risk of workplace injuries. Its rational and robust structure facilitates maintenance and compatibility with multiple product models, thereby effectively improving production efficiency and product yield.
