Description

Technical Field

[0001] The utility model relates to the technical field of solder paste printing jigs, and more specifically, to a solder paste printing jig. Background Art

[0002] In the existing technology, the existing solder paste printing jig needs to be replaced with different brush plates for different situations when it is used, and the existing equipment cannot be easily replaced, thus affecting the convenience of use. This is mainly reflected in the following aspects:

[0003] First, existing solder paste printing jigs often lack flexibility in design, resulting in the need to replace the corresponding brush plates when targeting electronic components of different sizes or shapes. However, existing equipment has many inconveniences in the process of replacing the brush plates. For example, special tools or equipment may be required to remove and install the brush plates, which not only increases the complexity of the operation, but also easily causes damage to the equipment or the brush plates. In addition, the process of replacing the brush plates may require a long time and effort, reducing production efficiency.

[0004] Secondly, the existing solder paste printing jigs are prone to production interruptions when replacing the brush plate. Since the replacement of the brush plate requires shutdown, this will cause the production line to stagnate, affecting production progress and output. At the same time, frequent shutdowns to replace the brush plate will also increase the cost of equipment repair and maintenance, increasing the operating burden of the enterprise. In addition, due to the inconvenience of replacing the brush plate, operators may need to receive special training, which increases labor costs and training costs. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a solder paste printing jig, which has the following beneficial effects:

[0018] 1. The design of the installation mechanism makes the process of replacing the brush plate easier and more efficient. Through the coordinated action of the pillar, the fixing rod, the brush plate and the fixing sleeve, the functions of quick replacement and firm fixation are realized. The brush plate passes through the fixing rod and fits on the pillar. The fixing sleeve is slidably connected to the fixing rod and pressed on the brush plate, ensuring the stable installation of the brush plate. In addition, the setting of the push rod and the fitting ring enables the rapid response and adaptation to brush plates of different sizes and shapes when replacing the brush plate, thereby improving the versatility and adaptability of the device. This design not only reduces the time and effort in replacing the brush plate, but also improves production efficiency and output.

[0019] 2. The design of the clamping mechanism effectively ensures the stability and reliability of the brush plate during the printing process. Through the combination of the push spring and the follower ball, as well as the matching of the chuck and the slot, a reliable clamping system is formed. When the clamping force needs to be adjusted, the chuck is clamped in the slot by rotating the vertical rod, thereby fixing the position of the synchronous disk. This design can not only adjust the clamping force as needed, but also ensure the stable movement of the brush plate during the printing process, thereby improving the printing quality and consistency.

[0020] 3. The design of the telescopic mechanism improves the flexibility and adaptability of the device. Through the combination of the synchronous disk and the fitting block, as well as the setting of the contraction groove, the position of the mobile frame inserted into the fixed sleeve can be adjusted, thereby changing the compression amount of the push spring, and then adjusting the clamping force. This design can flexibly adjust the configuration of the device according to brush plates of different sizes and shapes, thereby improving the versatility and adaptability of the device.

When it is necessary to adjust the clamping force of the follower ball 19 and the fixing rod 5, first, it is engaged with the two synchronous disks 10, and then the multiple vertical rods 15 are rotated so that the chuck 13 is clamped on the clamping groove 16. Since multiple clamping grooves 16 are provided, it can be ensured that the synchronous disk 10 is fixed in the corresponding position. When the two synchronous disks 10 are installed in different positions, the fitting block 11 abuts against the shrinkage groove 12, so the position of the movable frame 8 inserted into the fixing sleeve 4 can be adjusted, and then the compression amount of the push spring 18 can be changed, thereby changing the clamping force.

[0032] More specifically, the fixing of the brush plate 3 is ensured by the action of the fixing sleeve 4, and then the scraper 22 is driven by the mover 21 to complete the solder paste printing process.

[0033] In summary, when the overall device is in use or running: when it is necessary to replace a different brush plate 3, first, the brush plate 3 is passed through the fixing rod 5 to fit on the pillar 2, and then the fixing sleeve 4 is inserted into the fixing rod 5 so that the fixing sleeve 4 is pressed on the brush plate 3. When it is necessary to adjust the clamping force of the follower ball 19 and the fixing rod 5, first, the two synchronous disks 10 are engaged, and then the multiple vertical rods 15 are rotated to make the clamping disk 13 clamped on the clamping groove 16. Since multiple clamping grooves 16 are provided, it can be ensured that the synchronous disk 10 is fixed in the relative The two synchronous disks 10 are in the corresponding position. When the two synchronous disks 10 are installed in different positions, since the fitting block 11 is in contact with the shrinkage groove 12, the position of the movable frame 8 inserted into the fixed sleeve 4 can be adjusted, and then the compression amount of the push spring 18 can be changed, thereby changing the clamping force. When it needs to be fixed, it will continue to engage with the two synchronous disks 10, so that the fitting ring 7 on the push rod 6 is stuck in the annular groove 9. At this time, the two are in a rigidly connected state, and then the connection between the chuck 13 and the clamping groove 16 ensures the convenience of fixation.
