Abstract
Description
Technical Field
[0001] This utility model relates to the field of label technology, and in particular to a label for PFA carrier. Background Technology
[0002] In the semiconductor manufacturing industry, PFA (perfluoroalkoxy resin) materials are widely used in the manufacture of wafer carriers (such as basket carriers) due to their excellent chemical corrosion resistance, high temperature resistance, and low precipitation. These carriers need to be reused repeatedly in the semiconductor production process, and their surfaces usually need to be labeled or fixed with tags to identify the carrier number, batch information, or process parameters.
[0003] PFA carriers are used repeatedly in the semiconductor manufacturing environment for a long time. The labels on their surface will inevitably age. Once the label information cannot be read or identified, the carrier loses its traceability and cannot continue to be used. Existing labels are usually permanently or semi-permanently fixed to the PFA carrier body by means of bonding, hot melting, embedding or integral molding.
[0004] When fixed tags age and fail, they are extremely difficult to remove because they are tightly bonded to the PFA carrier. This requires specialized tools or chemical solvents, which is time-consuming and may damage the surface of the PFA carrier, even affecting the carrier's sealing and service life. Forcibly peeling them off can easily cause surface scratches and structural damage, affecting their cleanliness and mechanical properties, and may even lead to the scrapping of the entire high-value PFA carrier. Replacement is extremely inconvenient and can easily damage the carrier. Utility Model Content
[0005] In view of the problems of existing labels being extremely inconvenient to replace and easily damaging the vehicle, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a label for PFA carriers, which aims to quickly replace the label without damaging the PFA.
[0007] To solve the above technical problems, the present invention provides the following technical solution: a label for PFA carrier, comprising a PFA product, wherein a reserved cavity is provided on the PFA product, and a label assembly is disposed inside the reserved cavity;
[0008] The label assembly includes a fixed shell fixed inside a reserved cavity, and a carrier plate detachably installed inside the fixed shell, with a label mounted on the end face of the carrier plate away from the fixed shell.
[0009] First magnets are embedded in both sides of the carrier plate away from the fixed shell. Translation blocks are slidably installed on both sides inside the fixed shell. A second magnet is embedded in the side of the translation block near the end of the carrier plate and directly behind the first magnet. The opposing surfaces of the second magnet and the first magnet are in a magnetic attraction state.
[0010] As an improved technical solution, a buckle plate is fixed to the middle of one end face of the translation block near the fixed shell, and sliders are fixed to both notched ends of the buckle plate. Guide rails for sliding sliders are installed at the upper and lower positions inside the fixed shell.
[0011] As an improved technical solution, spring posts are installed between the two ends of the opposite sides of the two buckle plates, and springs are fixed between the spring posts on both sides.
[0012] As an improved technical solution, a push-pull protrusion is integrally formed and installed in the middle of the end face of the buckle near the fixed shell, and sliding cavities through which the push-pull protrusion passes are opened on both sides of the end face of the fixed shell away from the carrier plate.
[0013] As an improved technical solution, a third magnet is embedded at the end of the translation block away from the second magnet, and the opposing surfaces of the third magnet and the first magnet are in a state of magnetic repulsion.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are:
[0015] 1. In this utility model, as the push-pull protrusion is continuously squeezed, the third magnet gradually moves to the position of the original second magnet. Due to the magnetic repulsion between the third magnet and the first magnet, the carrier plate will be pushed out from the inside of the fixed shell under the action of magnetic thrust. There is no need to manually remove the carrier plate from the inside of the fixed shell, which further facilitates the removal of the carrier plate.
[0016] 2. This utility model uses the magnetic attraction of the first magnet and the second magnet to fix the label inside the fixed shell. The magnetic attraction installation means that when the original label ages, only the label needs to be replaced, without changing the carrier or damaging the original structure. At the same time, the removal process does not require auxiliary tools, greatly reducing manual operation time and significantly reducing production line downtime for maintenance. Furthermore, the repulsive force between the third magnet and the first magnet will push the label out of the fixed shell, further facilitating the removal of the label from the fixed shell.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1
[0026] Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a label for PFA carrier. This label for PFA carrier includes a PFA product 1, a reserved cavity 2 is provided on the PFA product 1, and a label component 3 is provided inside the reserved cavity 2.
[0027] The label assembly 3 includes a fixed shell 4 fixed inside the reserved cavity 2, and a carrier plate 5 detachably installed inside the fixed shell 4. The shape of the carrier plate 5 matches the shape of the inside of the fixed shell 4, and a label 6 is installed on the end face of the carrier plate 5 away from the fixed shell 4.
[0028] First magnets 7 are embedded on both sides of the end face of the carrier plate 5 away from the fixed shell 4. Translation blocks 12 are slidably installed on both sides inside the fixed shell 4. A second magnet 13 is embedded on the side of the translation block 12 close to the end face of the carrier plate 5 and located directly behind the first magnet 7. The opposite surfaces of the second magnet 13 and the first magnet 7 are in a magnetic attraction state.
[0029] A snap plate 15 is fixed to the middle of one end face of the translation block 12 near the fixed shell 4. A slider 9 is fixed to both notched ends of the snap plate 15. Guide rails 10 for sliding slider 9 are installed at the upper and lower positions inside the fixed shell 4.
[0030] Spring posts are installed between the two ends of the opposite sides of the two buckle plates 15, and springs 14 are fixed between the spring posts on both sides.
[0031] A push-pull protrusion 16 is integrally formed and installed in the middle of the end face of the buckle plate 15 near the fixed shell 4. Sliding cavities 8 are opened on both sides of the end face of the fixed shell 4 away from the carrier plate 5, through which the push-pull protrusion 16 passes.
[0032] During use, the label 6 is fixed inside the housing 4 by the magnetic attraction of the first magnet 7 and the second magnet 13. The magnetic attraction installation means that when the original label 6 ages, only the label 6 needs to be replaced, without changing the carrier or damaging the original structure. At the same time, the removal process does not require auxiliary tools, greatly shortening the manual operation time and significantly reducing the downtime of production line maintenance. Furthermore, the repulsive force between the third magnet 11 and the first magnet 7 will push the label 6 out of the housing 4, further facilitating the removal of the label 6 from the housing 4.
[0033] Example 2
[0034] Reference Figures 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a third magnet 11 is embedded and installed on the end of the translation block 12 away from the second magnet 13, and the opposite surfaces of the third magnet 11 and the first magnet 7 are in a state of magnetic repulsion.
[0035] During use, due to the magnetic repulsion between the third magnet 11 and the first magnet 7, the carrier plate 5 will be pushed out from the inside of the fixed shell 4 under the action of magnetic thrust, so that the carrier plate 5 does not need to be removed by hand from the inside of the fixed shell 4, which further facilitates the disassembly of the carrier plate 5.
[0036] The remaining structure is the same as that in Example 1.
[0037] Based on embodiments 1-2, the working principle of this utility model is as follows: In a static state, the positions of the two translation blocks 12 are positioned by the elasticity of the two springs 14. At this time, the carrier plate 5 is placed inside the fixed shell 4, and the back of the carrier plate 5 will abut against the front end of the translation block 12. At this time, the first magnet 7 and the second magnet 13 come into contact. Through the magnetic adsorption between the two, the carrier plate 5 is magnetically fixed inside the fixed shell 4, thus completing the installation of the label 6.
[0038] When it is necessary to disassemble and replace the label 6, pinch the push-pull protrusions 16 on both sides and apply pressure towards the center. The push-pull protrusions 16 on both sides slide towards the center inside the sliding cavity 8. During the sliding process, the spring 14 is compressed and the distance between the two translation blocks 12 on both sides is continuously shortened, so that the second magnet 13 and the first magnet 7 gradually make misaligned contact and magnetic adsorption. When the second magnet 13 and the first magnet 7 make contact and magnetic adsorption, the carrier plate 5 can be removed.
[0039] As the push-pull protrusion 16 is continuously squeezed, the third magnet 11 gradually moves to the original position of the second magnet 13. Due to the magnetic repulsion between the third magnet 11 and the first magnet 7, the carrier plate 5 will be pushed out of the inside of the fixed shell 4 under the action of magnetic thrust.
[0040] Release the pressure applied to the push-pull protrusion 16, and under the elastic reset action of the spring 14, the translation blocks 12 on both sides will reset.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
