Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and in particular to a surface treatment fixture for products without threaded holes. Background Technology

[0002] With the development of the IC equipment industry, the corrosion resistance of metals has always been of paramount importance. In the IC field, it relates to the overall service life of the equipment and the quality of film deposition. Various surface treatments are required for products to achieve high corrosion resistance and adhesion while maintaining conductivity. In the field of metal materials equipment, where lightweight metals are widely used, protection against rainwater and salt spray corrosion is also crucial. Therefore, the issue of surface treatment mounting is a key concern in practical use, significantly impacting overall performance. This is especially true for products without threaded holes, where the lack of threaded hole mounting stations presents a pressing problem that needs to be addressed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a surface treatment fixture for products without threaded holes.

[0004] The specific technical solution is as follows:

[0005] A surface treatment fixture for products without threaded holes includes a hanging rod, multiple clips, and a locking nut. A through hole is formed at a suitable location on the product. One end of the hanging rod is a hanging part, and the other end is a rod part. The hanging part and the rod part are connected by a transition edge. The hanging part is used to connect with a vehicle attachment. The end of the rod part has external threads. The hanging rod passes through the through hole of the product and is locked in place by the threaded engagement of the locking nut. The clips are fitted on the outside of the rod part, corresponding to the position of the through hole, and are spaced apart between adjacent products.

[0006] The transition edge is a frustum shape that tapers from the hanging part to the rod part.

[0007] The center of the hanging part has a threaded hole, and it is connected to the vehicle hanger by a screw. After connection, it can swing or rotate.

[0008] The buckle has a central hole and is fitted onto the outside of the rod. The diameter of the central hole is adapted to the hanging rod.

[0009] A notch is provided at the edge of the buckle for elastic cushioning and easy disassembly.

[0010] The number of through holes is determined according to the size of the product.

[0011] The buckle is made of Teflon.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention relates to the surface treatment field of IC equipment (specialized production equipment for semiconductor devices, integrated circuit chips, and flat panel displays) manufacturing, solving the problem of products requiring surface treatment lacking lifting holes. The hanging rod is connected to the production line trolley via screws, passing through the product's through-hole for fixation. Multiple clips on the hanging rod space the product, minimizing the contact area with the product. A nut locking device facilitates operation and ensures secure hanging during surface treatment, solving the problem of hanging without threaded holes. Furthermore, the sufficiently small contact area between the fixture and the product prevents scratching the product surface and ensures the product does not detach during processing. The number of clips and the hanging rod size can be adjusted to accommodate products of different sizes. A nut at the end of the hanging rod allows it to connect to various trolley fixtures, enabling swinging and rotation, and application in various surface treatment scenarios.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the structure of the fixture of this utility model. Figure 2 for Figure 1 A magnified view of a portion of point A in the diagram. Figure 3 This is a schematic diagram of the structure of the hanging rod of this utility model. Figure 4The figure shows a schematic diagram of the buckle structure of this utility model: The surface treatment fixture for products without threaded holes of this utility model includes a hanging rod 2, multiple Teflon buckles 3 and locking nuts 4; through holes 11 are opened at suitable positions on the product 1, and the number of through holes 11 is based on the size of the product 1; one end of the hanging rod 2 is a hanging part 21, and the other end is a rod part 22. The hanging part 21 and the rod part 22 are connected by a transition edge 23, which is a frustum shape that tapers from the hanging part 21 to the rod part 22. A threaded hole 24 is opened in the center of the hanging part 21, which is connected to the crane hanger by a screw. After connection, it can swing or rotate. The end of the rod 22 has an external thread 25. The hanging rod 2 passes through the through hole 11 of the product 1 and is locked with the locking nut 4 through the thread. The center hole 31 is opened in the center of the buckle 3, which is sleeved on the outside of the rod 22. The diameter of the center hole 31 is adapted to the hanging rod 2. The buckles 3 are spaced between adjacent products to separate the products 1 and prevent them from colliding. The contact area between the fixture and the product is small enough to avoid scratching the product surface and to ensure that the product can be surface treated as a whole. A notch 32 is opened at the edge of the buckle 3 for elastic cushioning and easy disassembly.

[0021] In use, the hanging rod 2 passes through the through hole 11 of product 1 and is spaced apart between adjacent products. The front end is locked with a locking nut 4. The threaded hole 24 of the hanging part 21 is connected to the crane hanger through a screw for the next surface treatment.

[0022] When product 1 needs to be removed, remove the locking nut 4, gradually remove product 1 by removing the buckle 3, and finally remove the hanging rod 2 for repeated use.
