Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to laser engraving positioning tooling. Background Technology

[0002] With the rapid development of semiconductor technology, electronic heat-generating components such as microprocessor chips generate a large amount of heat during operation. Therefore, most electronic products have internal heat dissipation structures to cool down these heat-generating electronic components.

[0003] Furthermore, typical heat dissipation structures use heat-generating electronic components attached to a heat-generating plate to ensure good electrical conductivity and evenly transfer the heat generated by the electronic components to the heat dissipation structure, thereby improving heat dissipation efficiency. In addition, since the surface of the heat-generating plate is a conductive surface, it needs to be flat and free of defects to enhance the heat dissipation effect.

[0004] A prior art patent with publication number CN217561315U discloses a solution including a heat-conducting sheet body. The heat-conducting sheet body includes a receiving groove and a positioning recess. The bottom surface of the positioning recess is non-planar and includes a quadratic curved surface. Accordingly, the heat-conducting sheet body will generate a clear bright area at the position of the positioning recess, thereby identifying the position of the positioning recess as a reference point, thereby defining a certain area of ​​the heat-conducting sheet body, and then performing detection within the range.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] Traditional laser engraving positioning fixtures mostly use L-shaped positioning blocks for simple positioning. However, since some annular heat exchange products have a chamfer on one corner and the widths of adjacent sides are different, in scenarios with high precision requirements, the product is often not placed properly or is placed upside down, which ultimately leads to a decrease in laser engraving yield.

[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a laser engraving positioning fixture, which solves the problem that traditional laser engraving positioning fixtures mostly use L-shaped positioning blocks for simple positioning. In scenarios with high precision requirements, this often results in products not being placed correctly or being placed upside down, ultimately leading to a decrease in laser engraving yield.

[0009] To achieve the above objectives, the present invention provides the following technical solution.

[0010] A laser engraving positioning fixture includes a fixture base plate, on which an L-shaped positioning block is fixed, and the product positioning angle is formed by the inner corner of the positioning block.

[0011] The tooling base plate is also equipped with lateral clamping components that slide along both the horizontal and vertical directions to clamp the outer wall of the product.

[0012] The tooling base plate also has anti-reverse plungers that slide horizontally and vertically to position the inner wall of the product.

[0013] As an optimized solution, the inner corner of the positioning block is provided with an anti-reverse C-angle to avoid the chamfer of the product.

[0014] As an optimized solution, the tooling base plate is further fixed with auxiliary positioning blocks in the two extension directions corresponding to the positioning block.

[0015] As an optimized solution, the tooling base plate has a handle position in the area between the auxiliary positioning block and the positioning block.

[0016] As an optimized solution, the lateral clamping assembly includes a slide mounted on the tooling base plate, and a lateral clamping block that abuts against the outer wall of the product is connected to the slide by a spring.

[0017] As an optimized solution, the slide has a guide groove, a guide post is horizontally fixed in the guide groove, the back of the lateral clamping block has a guide hole that matches the guide post, the spring is fitted on the guide post, and the two ends of the spring abut against the guide groove and the lateral clamping block respectively.

[0018] As an optimized solution, the tooling base plate is provided with a first guide groove, the slide is slidably installed in the first guide groove, two guide plates are fixedly connected to the opposite side walls of the upper end of the slide, the guide plates are provided with elongated guide holes along the sliding direction, and the tooling base plate is threaded with a first screw that abuts against the upper edge of the elongated guide hole.

[0019] As an optimized solution, a second guide groove is provided on the tooling base plate, and a slider is slidably provided in the second guide groove. The anti-reverse plunger is vertically fixed to the upper end of the slider. The slider is provided with an elongated countersunk guide hole along the sliding direction. A second screw that abuts against the upper edge of the elongated countersunk guide hole is threadedly connected to the second guide groove.

[0020] As an optimized solution, the upper end of the slider is provided with an insertion groove, and the anti-reverse plunger is vertically inserted into the insertion groove.

[0021] As an optimized solution, the edges of both the positioning block and the auxiliary positioning block are rounded.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The fixture base plate is equipped with an L-shaped positioning block with C-corners, which can match the chamfer of the annular heat spreader to achieve anti-reverse function; the positioning block has rounded corners to prevent product scratches; the fixture base plate also has a handle for easy product loading and unloading.

[0024] A slider is slidably installed in the second guide groove to adjust the position of the anti-reverse plunger, which can be used in situations where the widths of adjacent sides of the annular heat spreader are inconsistent. The anti-reverse plunger can be adjusted according to the shape of the product, thereby realizing the dual anti-reverse function of the product.

[0025] The slide block slides and adjusts its position within the first guide groove, allowing for free adjustment based on product size. The lateral clamping block is connected to the slide block via a spring, enabling clamping after the product is placed inside. Once the product is inside, the lateral clamping block can clamp and position the product in two directions, ensuring accurate and secure placement. This ensures accurate product positioning, prevents reverse placement, improves laser engraving yield, and enhances product appearance yield. Attached Figure Description
