Description

Technical Field

[0001] This utility model relates to the field of ultra-thin steel sheet processing, specifically a simple bonding fixture for ultra-thin steel sheets. Background Technology

[0002] With the continuous development of technology, the demand for ultra-thin steel sheets is increasing in many fields such as electronics, aerospace, and precision instruments. For example, in electronic products, in order to achieve thinner and higher-performance products, ultra-thin steel sheets are needed as supporting structures, heat dissipation components, or shielding materials for electronic components. When using such a fixture to assemble protective films, the fixture slots are too shallow and the products are thin, resulting in slight warping and insufficient stability when placed in the fixture slots, which can cause misalignment. Therefore, a simple bonding fixture for ultra-thin steel sheets is needed.

[0003] An existing simple bonding fixture for ultra-thin steel sheets typically involves milling corresponding grooves into an aluminum plate according to the product spacing requirements and thickness, then installing positioning pins. The product is then placed in the fixture groove, and the positioning pins are used to attach the protective film. However, this method of assembling the protective film has drawbacks. Because the fixture grooves are too shallow and the product is thin, slight warping occurs, resulting in insufficient stability within the fixture grooves and causing misalignment during bonding. Therefore, a simple bonding fixture for ultra-thin steel sheets is urgently needed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a simple bonding fixture for ultra-thin steel sheets, so as to solve the problem that when using existing simple bonding fixtures for ultra-thin steel sheets, the fixture groove is too shallow, the product is thin, there is slight warping, and the stability of the product placed in the fixture groove is not enough, which will cause bonding misalignment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple bonding fixture for ultra-thin steel sheets, comprising a fixture base plate, a fixture middle plate, and a fixture cover plate. Spring positioning pins are installed at the four corners of the fixture base plate. A contoured top block is installed on the surface of the fixture base plate. A fixture middle plate is installed at one end of the fixture base plate. A contoured groove is formed on the surface of the fixture middle plate. A blind hole is formed on the back of the fixture middle plate. Bonding positioning pins are installed on the surface of the fixture middle plate. A fixture cover plate is installed at one end of the fixture middle plate. A through hole is formed on the surface of the fixture cover plate. Foam is installed at one end of the fixture cover plate.

[0006] Preferably, the contouring top blocks are distributed at equal intervals with respect to the fixture base plate.

[0007] Preferably, the contour slots are evenly distributed on the middle plate of the fixture, and the middle plate of the fixture is perforated.

[0008] Preferably, the middle plate of the fixture is engaged with the bottom plate of the fixture by a spring positioning pin, and the middle plate of the fixture and the bottom plate of the fixture are in close contact.

[0009] Preferably, the fixture cover is perforated and fits tightly against the foam.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the setting of a fixture base plate, spring positioning pin, contour top block, fixture middle plate, contour groove, back blind hole, bonding positioning pin, fixture cover plate and through hole, designs a press-lift bonding fixture, deepens the fixture groove, and, in conjunction with the spring positioning pin, presses the fixture cover plate to make the top block on the fixture base plate make perpendicular contact with the upper plate, so as to achieve effective bonding between the product in the groove and the protective film, and the bonding accuracy meets the product requirements.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figure 1-5A simple bonding fixture for ultra-thin steel sheets includes a fixture base plate 1, a fixture middle plate 4, and a fixture cover plate 8. Spring positioning pins 2 are installed at the four corners of the fixture base plate 1. Contouring top blocks 3 are installed on the surface of the fixture base plate 1 at equal intervals. The fixture middle plate 4 is installed at one end of the fixture base plate 1. Contouring grooves 5 are formed on the surface of the fixture middle plate 4 at equal intervals, and the fixture middle plate 4 is perforated. The fixture base plate with the contouring top blocks 3 is installed in the device. 1 can be fitted with the middle plate 4 of the fixture with the contour groove 5 to maintain a tight fit. The surface of the middle plate 4 of the fixture has a blind hole 6 on the back. The surface of the middle plate 4 of the fixture is equipped with a fitting positioning pin 7. A fixture cover plate 8 is installed at one end of the middle plate 4 of the fixture. The surface of the fixture cover plate 8 has a through hole 9.
