Description

Technical Field

[0001] This utility model relates to a tooling technology, in particular to a welding tooling, specifically a multi-stage adjustable temperature fuse welding tooling. Background Technology

[0002] Currently, in industries such as heater manufacturing, home appliance electronics, and industrial control, thermal fuses are widely used as the core component for overheat protection to ensure circuit safety. During product development and safety certification, multiple fuses are often connected in series to verify their reliability and redundancy under extreme conditions. In mass production assembly, fuses must be accurately soldered onto circuit boards to achieve functional integration. Thermal fuses generally come in various sizes (common diameters φ3mm~φ8mm) and are sensitive to overheating. Currently, traditional processes still rely on operators using metal tweezers to hold the fuse leads in the middle for heat dissipation and manually soldering them, avoiding direct contact between the soldering iron and the fuse body.

[0003] However, this traditional welding process has significant problems: during operation, the tweezers are prone to accidental slippage, scratching the coating on the fuse surface and affecting its protective performance and durability. Simultaneously, the difficulty in precisely controlling the clamping force and position leads to uneven heat distribution during welding, causing overheating and excessive heat transfer to the fuse body, resulting in material damage. These problems severely impact product reliability and welding yield. Utility Model Content

[0004] The purpose of this invention is to address the problems of high defect rate and low efficiency in existing fuse welding, and to design a multi-stage adjustable temperature fuse welding fixture.

[0005] The technical solution of this utility model is:

[0006] A multi-platform adjustable temperature fuse welding fixture includes multiple platforms 3, characterized in that: the multiple platforms 3 are movably mounted on two parallel lead screws 7, the distance between each platform 3 is adjustable to meet welding requirements, the two ends of the lead screws 7 are mounted on corresponding lead screw supports 8, and each platform 3 is equipped with a left spring 1 and a right spring 2, and the distance between the left spring 1 and the right spring 2 is adjustable to meet the welding requirements of fuses of different sizes.

[0007] The beneficial effects of this utility model are:

[0008] Multi-stage synchronous operation is adopted: each multi-stage can be equipped with a spring clip holding mechanism, which can hold multiple thermal fuses at one time, significantly improving welding efficiency.

[0009] Multi-diameter compatibility: By adjusting the spring hole position and tightening the bolt, it can be adapted to common thermal fuse diameters in the range of φ3mm~φ8mm, without the need for frequent clamp changes.

[0010] High-efficiency heat dissipation protection: The combination of high thermal conductivity materials and hollow structure design effectively reduces the thermal shock of high welding temperature to the fuse temperature sensing element, avoiding internal component failure.

[0011] Precise and stable clamping: The anti-slip spring pattern ensures precise fuse positioning and accurate pin alignment during welding, improving welding yield; the spring and bolt mating structure ensures stable clamping force and simple operation. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the assembly structure of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 As shown.

[0016] A multi-platform adjustable temperature fuse welding fixture includes multiple platforms 3, which are movably mounted on two parallel lead screws 7. The distance between each platform 3 is adjustable to meet welding requirements. Corresponding lead screw supports 8 are mounted at both ends of the lead screws 7. A left spring 1 and a right spring 2 are mounted on each platform 3, and the distance between the left spring 1 and the right spring 2 is adjustable to meet the welding requirements of fuses of different sizes. Figure 2 As shown, the end of the lead screw 7 is threaded, and the threaded end passes through the lead screw support 8 and is fitted with a lead screw nut 5 to position the lead screw support 8. The left spring 1 and right spring 2 are mounted on both sides of the platform 3 by fixing bolts 6. The left spring 1 or right spring 2 is fixed to one side of the platform by the fixing bolts 6, while the right spring 2 or left spring 1 is positioned by spring nuts 4 on the end of the fixing bolts 6 that pass through the platform 3. Each platform 3 is screwed with at least two fixing bolts 6 for positioning the left spring 1 and right spring 2. In specific implementation, to increase heat dissipation, heat dissipation holes 9 can be provided on both the left spring 1 and right spring 2. Simultaneously, the outer sides of the left spring 1 and right spring 2 can be designed as heat dissipation fins to improve heat dissipation performance. Figure 1 Similarly, to enhance the anti-slip effect, anti-slip textures (not shown in the figure) can be provided on the side of the left spring 1 and / or the right spring 2 that contacts the fuse.

[0017] Details are as follows:

[0018] The welding fixture of this utility model adopts two high-strength, lightweight lead screws 7 arranged in parallel, with lead screw supports 8 fixed at both ends by nuts 5. A multi-platform 3 can move horizontally on the lead screws 7, and the operator can manually adjust its position on the lead screws 7 by pulling the platform 3. Each platform 3 has a set of arc-shaped heat dissipation springs 1 and 2 with multiple round holes fixed to its outer side. Through-bolts 6 pass sequentially through the coaxial round holes of the springs on both sides and are locked with spring nuts 4. When the bolts 6 are tightened, the left spring 1 is compressed and deformed inward, reducing the clamping opening to hold small-diameter fuses; when loosened, the left spring 1 springs back, expanding the clamping opening to accommodate large-diameter fuses. The inner side of the left spring 1 and / or right spring 2 is designed with anti-slip textures to enhance clamping stability, and the outer side has a heat dissipation fin structure to improve heat dissipation performance. The platform 3, lead screw 7, left spring 1 and right spring 2 are all made of high thermal conductivity materials, which can quickly dissipate welding heat. The overall structure significantly improves work efficiency and product reliability while ensuring operational adaptability.

[0019] This utility model has the following significant features:

[0020] High-efficiency parallel operation: Supports synchronous operation of multiple platforms, and can clamp and weld multiple thermal fuses at one time, greatly improving work efficiency.

[0021] Wide size adaptability: With adjustable spring and bolt locking mechanism, various fuses with diameters ranging from φ3mm to φ8mm can be stably clamped without replacing any parts, which enhances the versatility of the equipment and the flexibility of the production line.

[0022] Improved heat dissipation performance: The use of high thermal conductivity materials and heat sink fin structure effectively suppresses the accumulation of welding heat, reduces thermal damage to the fuse temperature sensing element, and protects its electrical characteristics and long-term reliability.

[0023] High-precision and stable clamping: The anti-slip texture on the inner side of the spring sheet works in conjunction with the linkage mechanism to achieve uniform clamping force and accurate pin alignment, effectively reducing welding misalignment or poor soldering and significantly improving yield.

[0024] The method of using this utility model is as follows:

[0025] During operation, first adjust the tightness of the fixing bolt 6 according to the diameter of the thermal fuse to be soldered; place the fuse into the clamp between the left spring 1 and the right spring 2, and slowly tighten the spring nut 4, causing the left spring 1 and the right spring 2 to be compressed and deformed inward until the anti-slip texture on the inner side of the spring is tightly attached to the surface of the fuse, thus completing the clamping and fixing of a single fuse; repeat the above operation to complete the fuse clamping operation of the multi-stage platform. Place multiple thermal fuses in the spring clamping areas of each station, ensuring that the leads of all fuses remain aligned, and finely adjust the spacing between fuses by manually moving the position of the stage 3 on the lead screw 7 to ensure even distribution. After positioning, use a soldering iron to perform the soldering operation. During the soldering process, the spring and the external heat dissipation fin structure can effectively dissipate heat to prevent the fuse body from overheating. After the fuse is soldered, wait for the overall temperature of the fixture to drop to room temperature, loosen the spring nut 4, the left spring 1 and the right spring 2 will spring back and open, and the soldered fuse can be removed, completing one soldering operation cycle.

[0026] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
