Description

Technical Field

[0001] This utility model relates to the field of surface mount product processing technology, specifically to a pre-soldering fixture for surface mount semiconductor products. Background Technology

[0002] For surface mount semiconductor products, such as surface acoustic wave resonators and filters, the surface mount surface of the product needs to be soldered by a pre-soldering machine. In actual use, the product is placed directly on the workbench, and the pre-soldering machine performs soldering operations on the surface of the product through the soldering head.

[0003] Traditional techniques use flat worktables without positioning structures. During welding, the movement of the welding head of the pre-welding machine can easily cause product displacement, resulting in welding deviations or even product damage. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a pre-soldering fixture for surface mount semiconductor products, which solves the problem that the existing technology uses a planar worktable without a positioning structure.

[0005] To achieve the above and other related objectives, this utility model provides a pre-soldering fixture for surface mount semiconductor products, including a worktable, wherein the lower end of the worktable is provided with an assembly groove and the upper end is provided with a limiting groove; the worktable is fixed by screwing bolts into the assembly groove.

[0006] The worktable is equipped with an adjustable clamp;

[0007] The fixture has multiple positioning surfaces, and positioning grooves are provided on the positioning surfaces. A first magnet is provided in the positioning grooves.

[0008] The size of the positioning grooves distributed on the multiple positioning surfaces increases sequentially to accommodate the positioning of multiple filter models.

[0009] In one embodiment of this utility model, the clamp has a regular hexahedral structure.

[0010] In one embodiment of this utility model, the limiting groove is configured as a square that adapts to the positioning surface of the clamp;

[0011] A sector-shaped groove is provided at multiple included corners of the square limiting groove. A separable sector-shaped positioning block is fitted in the sector-shaped groove. A second magnet is provided at the lower end and the cross-sectional end of the sector-shaped positioning block.

[0012] In one embodiment of this utility model, the height of the sector-shaped positioning block is greater than the depth of the sector-shaped groove.

[0013] In one embodiment of this utility model, the assembly groove is configured as a long groove structure, and multiple bolts can be screwed into the same assembly groove at the same time.

[0014] In one embodiment of this utility model, two assembly slots are provided, which are distributed on the lower ends of opposite sides of the worktable.

[0015] In one embodiment of this utility model, both the first magnet and the second magnet are permanent magnets.

[0016] As described above, the pre-soldering fixture for surface mount semiconductor products of this invention has the following beneficial effects:

[0017] 1. By setting up a fixture with a positioning groove and a first magnet, the product can be positioned on the fixture by the positioning groove and fixed by the first magnet. In addition to being limited in the horizontal direction, the product is also fixed in the vertical direction in the fixture, which prevents the welding head from moving and causing the product to move during the welding process. This ensures that the relative position between the welding head and the product is completely fixed, improving the welding effect. Furthermore, the fixture can also ensure the consistency of welding of batch products.

[0018] 2. By designing the fixture as a regular hexahedron structure, multiple positioning surfaces on the fixture can be installed in the limiting slots of the worktable; positioning slots of different sizes and specifications are provided on multiple positioning surfaces, which can be adapted to the positioning of multiple models of products, making one structure multi-purpose and improving the utilization rate of the fixture.

[0019] 3. By setting up a fan-shaped slot and a fan-shaped positioning block for coordinated use, after the fixture is placed relative to the worktable, the fan-shaped positioning block is placed into the fan-shaped slot. The fan-shaped positioning block attracts the worktable and the fixture simultaneously through the second magnet, which improves the reliability of the fixture being placed relative to the worktable.

[0020] 4. The pre-soldering fixture for surface mount semiconductor products provided by this utility model is designed to limit the product in multiple ways, avoiding the problem of product displacement caused by the movement of the soldering head during the soldering process, and improving the soldering effect; the hexahedral structure of the fixture can be adapted to the positioning of multiple product models, improving the utilization rate of the fixture; the cooperative design of the sector groove and sector positioning block can improve the reliability of the fixture placement relative to the worktable.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] Please see Figure 1-4 This utility model provides a pre-soldering fixture for surface mount semiconductor products, including a worktable 1. The lower end of the worktable 1 is provided with an assembly groove 11 and the upper end is provided with a limiting groove 12. The worktable 1 is fixed by screwing bolts into the assembly groove 11. The assembly groove 11 is designed as a long groove structure, and multiple bolts can be screwed into the same assembly groove 11 at the same time, which can improve the installation and fixing effect of the worktable. There are two assembly grooves 11, which are distributed on the lower ends of opposite sides of the worktable 1. Screwing bolts from both sides can further improve the reliability of the installation and fixing of the worktable.

[0030] The workbench 1 is equipped with an adjustable clamp 2. The clamp 2 has multiple positioning surfaces, and positioning grooves 21 are provided on the positioning surfaces. A first magnet 22, which is a permanent magnet, is provided in the positioning grooves 21. By setting the clamp 2 and providing the positioning grooves 21 and the first magnets 22 on the clamp 2, the product can be placed on the clamp 2 and limited by the positioning grooves 21 and fixed by the adsorption of the first magnets 22. In addition to being limited in the horizontal direction, the product is also fixed by force in the vertical direction in the clamp 2, which avoids the movement of the welding head causing the product to move during the welding process, and ensures that the relative position between the welding head and the product is completely fixed, thereby improving the welding effect of the product. Furthermore, the setting of the clamp can also ensure the consistency of welding of batch products.

[0031] The fixture 2 has a regular hexahedral structure, and the limiting groove 12 is set as a square to fit the positioning surface of the fixture 2 so that the fixture 2 can be placed on the worktable 1. The size of the positioning grooves 21 distributed on the multiple positioning surfaces increases sequentially to accommodate the positioning of multiple types of filters. By setting the fixture 2 as a regular hexahedral structure, multiple positioning surfaces on the fixture 2 can be installed in the limiting grooves 12 of the worktable 1. The multiple positioning surfaces are provided with positioning grooves 21 of different sizes and specifications, which can accommodate the positioning of multiple types of products. One structure serves multiple purposes, improving the utilization rate of the fixture 2.

[0032] Sector-shaped grooves 13 are provided at multiple included corners of the square limiting groove 12. Separable sector-shaped positioning blocks 14 are fitted into the sector-shaped grooves 13. Second magnets 15, which are permanent magnets, are provided at the lower end and cross-sectional end of the sector-shaped positioning blocks 14. At least the area where the worktable 1 contacts the lower end of the sector-shaped positioning block 14 and the area where the clamp 2 contacts the cross-sectional end of the sector-shaped positioning block 14 are made of a ferromagnetic material that can be attracted by magnets. After the clamp 2 is placed relative to the worktable 1, the sector-shaped positioning block 14 is placed into the sector-shaped groove 13. The sector-shaped positioning block 14 simultaneously attracts the worktable 1 and the clamp 2 through the second magnets 15, improving the reliability of the clamp 2's placement relative to the worktable 1. The height of the sector-shaped positioning block 14 is greater than the depth of the sector-shaped groove 13, facilitating the removal and placement of the sector-shaped positioning block 14.

[0033] In summary, the pre-soldering fixture for surface-mount semiconductor products provided by this utility model, with the design of fixture 2, can limit the product in multiple ways, avoiding the problem of product displacement caused by the movement of the soldering head during the soldering process, thus improving the soldering effect. The hexahedral structure design of fixture 2 can be adapted to the positioning of multiple product models, improving the utilization rate of fixture 2. The cooperative design of the sector-shaped groove 13 and the sector-shaped positioning block 14 can improve the reliability of the placement of fixture 2 relative to the worktable 1. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
