A patch auxiliary fixture for sheet products

Abstract

This utility model relates to an auxiliary fixture for patching sheet products, including a base plate. The base plate has a positioning component and several grooves. The grooves are used to place a single product. The positioning component includes a first positioning post and a second positioning post. The first positioning post is located at the side end of each of the grooves, and the second positioning post is located below each of the grooves. Compared with the prior art, the auxiliary fixture for patching sheet products provided by this utility model achieves millimeter-level alignment between the product and the sheet through a groove-to-product contour matching design, combined with the insertion of the first and second positioning posts into positioning holes. This completely eliminates the positional deviation of manual patching, making the product patching more precise and improving product yield.

Description

Technical Field

[0001] This utility model relates, and in particular, to an auxiliary fixture for patching sheet products. Background Technology

[0002] In the electronics industry, with the development of the industry, assembly plants have basically abandoned manual assembly after receiving die-cut parts. Currently, many die-cut products are made of sheets for customers to assemble. In the electronics die-cutting industry, sheet products (such as flexible circuit boards and optical films) often have 5%-10% local defects (such as missing corners and dents) due to the limitations of the stamping process.

[0003] Traditional patching processes typically involve removing defective products and then manually patching them. When manually handling patch products with tweezers, the position is determined by visual comparison, often resulting in errors exceeding ±0.5mm. The PET material of the positioning film is easily deformed, and manual pressing causes hole misalignment, leading to a misalignment rate of over 30% between the patch and the original hole. Batch processing is impossible; skilled workers need to adjust the patch 3-5 times per patch. Patch misalignment can cause assembly failures (such as FPC gold finger misalignment), leading to customer returns. Manual contact with the product can also introduce electrostatic damage. Therefore, traditional patching processes suffer from insufficient positioning accuracy, efficiency bottlenecks, and quality risks.

[0004] Although there are general positioning fixtures in the existing technology, none of them are designed for the multi-hole collaborative positioning and contour matching requirements of sheet patches. The fixtures are incompatible with product deformation and cannot completely solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary fixture for patching sheet products, which is used for product patching.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A patch auxiliary fixture for sheet products includes a base plate, the base plate having a positioning component and a plurality of grooves for placing a single product.

[0008] The positioning component includes a first positioning post and a second positioning post. The first positioning post is provided on the side end of a plurality of grooves, and the second positioning post is provided below the plurality of grooves.

[0009] In one embodiment of this utility model, a plurality of the products are disposed on a product positioning film, and the product positioning film contains sheet products that need to be patched.

[0010] In one embodiment of this utility model, the product positioning film is provided with a first positioning hole and a second positioning hole, the first positioning hole being located at the side end of the product and the second positioning hole being located at the bottom of the product.

[0011] In one embodiment of this utility model, the product shape is composed of two irregular rectangles, including a first rectangle, a second rectangle, and a third rectangle. One end of the first rectangle has a protrusion, and the first positioning hole is located on one side of this protrusion.

[0012] The other end of the first rectangle overlaps with one end of the second rectangle. The end of the second rectangle away from the first rectangle is provided with a third rectangle, and the end of the third rectangle away from the second rectangle is provided with a second positioning hole.

[0013] In one embodiment of this utility model, the first positioning hole is circular, the second positioning hole is rectangular, and the length of one side of the second positioning hole is slightly greater than the length of one side of the third rectangle.

[0014] In one embodiment of this utility model, the shape of the groove matches the shape of the product.

[0015] In one embodiment of this utility model, the height of the first positioning post is 2-4 mm, preferably 3 mm.

[0016] In one embodiment of this utility model, the height of the second positioning post is 2-4 mm, preferably 3 mm.

[0017] In one embodiment of this utility model, the first positioning post is circular in shape, and the second positioning post is rectangular in shape.

[0018] In one embodiment of this utility model, the base plate is made of aluminum plate.

[0019] As a preferred technical solution, after the aluminum plate is milled flat, a groove is milled at the product placement position.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The sheet patching auxiliary fixture provided by this utility model is designed to match the contour of the product with the groove. Combined with the insertion of the first positioning post and the second positioning post into the positioning hole, it realizes the millimeter-level alignment between the product and the sheet, completely eliminating the positional deviation of manual patching. This can make the product patching position more accurate and improve the product yield.

[0022] 2. The patch auxiliary fixture for sheet products provided by this utility model prevents incorrect placement of the positioning film by using the differentiated structure of circular positioning posts and rectangular positioning posts.

[0023] 3. The patching auxiliary fixture for sheet products provided by this utility model simplifies the patching operation to three steps: "placement-positioning-assembly". It eliminates the need for repeated adjustments, making the patching process faster and reducing the time spent on frequent manual alignment.

[0024] 4. The sheet material patching auxiliary fixture provided by this utility model supports the pre-placement of multiple products through grooves, realizing continuous batch patching; the aluminum base plate ensures that the fixture does not deform during long-term use, and the maintenance cost is close to zero.
