Description

Technical Field

[0001] This utility model relates to the field of mobile phone button processing technology, and more specifically, to a mobile phone button processing etching fixture. Background Technology

[0002] Mobile phone buttons are an important part of mobile phones, with main functions including dialing, text input, and sending messages. Traditional mobile phone buttons are made by CNC machining, which is costly and has low production capacity. With social development and price competition, they have gradually lost their advantage. Therefore, a process of etching and laser cutting has emerged to improve processing efficiency, allowing for mass production with high capacity and low cost.

[0003] During etching, a fixture is needed to position and fix the substrate for easy etching. However, traditional fixtures have a simple structure, only using a limiting groove to limit the substrate. After etching, they need to be moved to the laser cutting area and fixed again by bolts before cutting. During etching, the substrate may become loose, allowing the etching solution to seep into non-target areas and cause corrosion on the button surface. Furthermore, the secondary positioning process requires time to rotate the nuts, which is inefficient and inconvenient for disassembly, installation, replacement, and adjustment of the substrate. Therefore, a new etching fixture for mobile phone button processing is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile phone button etching fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone button etching fixture, including a support frame, a positioning groove in the middle of the support frame, positioning posts fixedly connected around the inner cavity of the positioning groove, a rubber ring sleeved in the middle of the positioning posts, a substrate plate in the middle of the positioning groove, and a pressure plate on the top of the substrate plate. The positioning groove supports and limits the substrate plate, the positioning posts position the substrate plate and the pressure plate, and the pressure plate squeezes the substrate plate to fix it. The substrate plate and the pressure plate are respectively provided with a first positioning hole and a second positioning hole around their perimeters. The top of the substrate plate is provided with an etching groove, and the surface of the pressure plate is provided with etching holes. The installation positions of the pressure plate and the substrate plate can be positioned by a positioning post passing through the middle of the first positioning hole and the second positioning hole. The rubber ring is squeezed to provide a buffering effect. The etching holes allow external etching liquid to etch the surface of the substrate plate, thereby etching the etching groove. The desired shape of the mobile phone button can be obtained by cutting the etching groove on the surface of the substrate plate with a laser cutting machine. The support frame has limit grooves around its top perimeter, and a limit plate is provided in the middle of the limit grooves. A pressure block is fixedly connected to the top of the limit plate, and a stabilizing plate and a stabilizing rod are inserted into the middle of the limit plate. A spring is sleeved on one end of the stabilizing rod. The spring pushes the limit plate, causing one end of the pressure block to move to the top of the pressure plate. The inclined surface at the bottom of one end of the pressure block can also squeeze the pressure plate, thereby squeezing the base plate and improving the stability of the base plate. The stabilizing plate further improves the stability of the movement of the limit plate.

[0006] Preferably, the substrate plate is positioned in the middle of the positioning groove, the positioning post passes through the middle of the first positioning hole and the second positioning hole, and the rubber ring is positioned at the bottom of the substrate plate. The positioning groove supports the substrate plate, and the positioning post passes through the first positioning hole and the second positioning hole to position the substrate plate and the pressure plate, thereby improving installation stability.

[0007] Preferably, the etching holes are adapted to the etching tanks, and the etching hole array is disposed on the surface of the pressure plate. The etching holes can prevent the etching liquid from adhering to the substrate, thereby etching to form the etching tanks.

[0008] Preferably, one end of the pressure block has a tapered cross-sectional shape, and one end of the pressure block extends to the top of the pressure plate. The bottom slope of the pressure block is in contact with the wall of the pressure plate. By pressing the wall of the pressure plate with the slope of one end of the pressure block, the pressure plate can exert a compressive force on the substrate.

[0009] Preferably, the limiting plate is adapted to the limiting groove, and both the stabilizing rod and the stabilizing plate are fixed in the inner cavity of the limiting groove, thereby improving the stability of the movement of the limiting plate through the stabilizing plate.

[0010] Preferably, the spring is located on the side of the limiting plate away from the pressure plate, and the actuating plate is located on the side of the pressure block close to the spring. By pushing the limiting plate with the spring, the pressure block can generate a force to move to the top of the pressure plate, which is convenient for squeezing and positioning.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model first uses a pressure plate to squeeze the substrate plate, which allows the etching liquid to enter the etching hole during etching and directly etch the corresponding position on the surface of the substrate plate to form the desired shape. This avoids the etching liquid from seeping into non-target areas. During etching and laser cutting, the pressure block is always squeezed against the pressure plate or substrate plate to achieve limiting and fixing. The pressure block can be moved by moving the toggle plate and pushed by the rubber ring, which facilitates installation and disassembly, thereby adjusting and replacing the substrate plate and improving the performance. 2. This utility model also uses a positioning post to position the substrate plate through the non-aligned positioning post, and a positioning post to position the pressure plate through the second positioning hole. The positioning groove supports and limits the substrate plate around its perimeter, making it easy to install and use. Furthermore, the cooperation of the stabilizing plate and the stabilizing rod can improve the stability of the limiting plate sliding inside the limiting groove, thereby improving the stability of the pressure block movement and making it easy to operate and use. In summary, through the interaction of the above-mentioned multiple functions, it is convenient to etch the corresponding positions on the surface of the substrate board to etch it into the desired shape, avoid the etching solution from seeping into non-target areas, and facilitate the positioning and fixing of the substrate board and pressure plate during etching and laser cutting, as well as convenient installation and disassembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-5The mobile phone button etching fixture shown includes a support frame 1, a positioning groove 2 in the middle of the support frame 1, positioning posts 3 fixedly connected around the inner cavity of the positioning groove 2, a rubber ring 10 sleeved in the middle of the positioning posts 3, a substrate plate 4 in the middle of the positioning groove 2, and a pressure plate 7 on the top of the substrate plate 4. The positioning groove 2 supports and limits the substrate plate 4, the positioning posts 3 position the substrate plate 4 and the pressure plate 7, and the pressure plate 7 squeezes the substrate plate 4 to fix the substrate plate 4. The substrate plate 4 and the pressure plate 7 are respectively provided with a first positioning hole 5 and a second positioning hole 9 around their perimeters. An etching groove 6 is provided on the top of the substrate plate 4, and an etching hole 8 is provided on the surface of the pressure plate 7. The positioning post 3 passes through the middle of the first positioning hole 5 and the second positioning hole 9, which can position the installation position of the pressure plate 7 and the substrate plate 4. The rubber ring 10 is squeezed to play a buffering role. The etching hole 8 allows the external etching liquid to etch the surface of the substrate plate 4, thereby etching the etching groove 6. The desired shape of the mobile phone button can be obtained by cutting the etching groove 6 on the surface of the substrate plate 4 with a laser cutting machine. Limiting grooves 11 are formed around the top of the support frame 1. A limiting plate 12 is set in the middle of the limiting grooves 11. A pressure block 13 is fixedly connected to the top of the limiting plate 12. A stabilizing plate 14 and a stabilizing rod 15 are inserted in the middle of the limiting plate 12. A spring 16 is sleeved on one end of the stabilizing rod 15. The spring 16 pushes the limiting plate 12, causing one end of the pressure block 13 to move to the top of the pressure plate 7. The inclined surface at the bottom of one end of the pressure block 13 can squeeze the pressure plate 7, thereby squeezing the base plate 4 and improving the stability of the base plate 4. The stabilizing plate 14 also improves the stability of the movement of the limiting plate 12.

[0020] As attached Figure 1-5As shown, the substrate plate 4 is positioned around the center of the positioning groove 2. The positioning post 3 passes through the center of the first positioning hole 5 and the second positioning hole 9. The rubber ring 10 is positioned at the bottom of the substrate plate 4. The etching holes 8 are adapted to the etching groove 6. The etching holes 8 are arrayed on the surface of the pressure plate 7. One end of the pressure block 13 has a tapered cross-section and extends to the top of the pressure plate 7. The bottom slope of the pressure block 13 fits against the wall of the pressure plate 7. The limiting plate 12 is adapted to the limiting groove 11. The stabilizing rod 15 and the stabilizing plate 14 are both fixed in the inner cavity of the limiting groove 11. The spring 16 is positioned on the side of the limiting plate 12 away from the pressure plate 7. The actuating plate 17 is positioned... The pressure block 13 is placed on the side near the spring 16. It supports the substrate plate 4 through the positioning groove 2. The positioning post 3 passes through the first positioning hole 5 and the second positioning hole 9 to position the substrate plate 4 and the pressure plate 7, improving installation stability. The etching hole 8 prevents the etching liquid from sticking to the substrate plate 4, thereby etching to form the etching groove 6. The pressure block 13 is pressed against the wall of the pressure plate 7 by one end, so that the pressure plate 7 can exert a pressing force on the substrate plate 4. The stabilizing plate 14 improves the stability of the movement of the limiting plate 12. The spring 16 pushes the limiting plate 12, so that the pressure block 13 can generate a force to move to the top of the pressure plate 7, which is convenient for pressing and positioning.

[0021] The working principle of this utility model is as follows: When in use, the substrate plate 4 is placed in the middle of the positioning groove 2, and the substrate plate 4 is positioned by the positioning post 3 passing through the first positioning hole 5. Then, the pressure plate 7 is installed on the top of the substrate plate 4, so that the top of the positioning post 3 passes through the second positioning hole 9 to position the pressure plate 7. During installation, the substrate plate 4 and the pressure plate 7 will press against the pressure block 13, causing the pressure block 13 to drive the limiting plate 12 to press against the spring 16 until the substrate plate 4 and the pressure plate 7 move to the bottom of the pressure block 13. At this time, through the push of the limiting plate 12 by the spring 16, one end of the pressure block 13 will move to the top of the pressure plate 7 and press against the wall of the pressure plate 7, thereby causing the pressure plate 7 to press against the substrate plate 4. During the etching process, liquid is introduced into the etching hole 8 to etch the surface of the substrate 4 into an etching groove 6. Then, pull multiple actuating plates 17, and push the substrate plate 4 through the rubber ring 10, so that the pressure plate 7 moves from the top of the substrate plate 4 in sequence, so that one end of the pressure block 13 presses the substrate plate 4. Then, the support frame 1 carries the substrate plate 4 to the laser cutting machine, and laser cuts the position of the etching groove 6 to form the desired shape, which is convenient for processing and use.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
