Description

Technical Field

[0001] This utility model relates to the field of screen manufacturing technology, specifically to a fixture for screen coating. Background Technology

[0002] Nano-coating for mobile phones is a branch of chemical coating. It involves uniformly applying nano-sized liquid silica to the surface of the mobile phone screen and then using specialized equipment to form a coating. Mobile phone screen coating refers to applying a protective layer to the surface of the mobile phone screen, making the screen surface more wear-resistant and with a better feel, thus providing good protection for the screen.

[0003] Traditional screen coating typically employs two independent drive mechanisms. However, achieving perfect synchronization in the starting, operating speed, and stroke endpoint of these two mechanisms is challenging. This asynchrony leads to asymmetrical forces on the screen during positioning, causing inaccurate positioning and potential damage to the screen edges due to excessive localized stress. Furthermore, after the screen is fixed, uneven clamping forces at both ends pose a risk of inconsistent tightness. Therefore, a new fixture for screen coating production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for screen coating production, addressing the problem mentioned in the background art where traditional screen coating typically employs two independent drive mechanisms. Because the starting speed, movement speed, and stroke endpoint of these two mechanisms are difficult to synchronize perfectly, this asynchrony leads to asymmetrical forces on the screen during positioning. This not only causes inaccurate screen positioning but also damages the screen edges due to excessive local stress. Furthermore, after the screen is fixed, the uneven clamping forces at both ends pose a risk of inconsistent tightness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for screen production coating, comprising...

[0026] Example

[0027] Please see Figure 1-5 This utility model provides a technical solution: a fixture for screen production coating, including a support frame 1, a fixing component on the support frame 1, and a driving component at the bottom of the support frame 1;

[0028] By setting a fixing component, the two guide rods 3 at both ends can move synchronously to correct and position the screen and fix it, effectively reducing errors. The fixing component includes four guide rods 3, four fixing rings 4, and two moving plates 5. The top of the support frame 1 has four guide slots 2, and the four guide rods 3 pass through the four guide slots 2 respectively. The four fixing rings 4 are fixedly sleeved on the top outer side of the four guide rods 3. The two ends of the two moving plates 5 are respectively sleeved on the outer side of the two guide rods 3 at one end. The bottom of each of the two moving plates 5 is fixedly connected to a fixing shaft 8. The outer side of each of the two fixing shafts 8 is movably sleeved with one end of a pull rod 9. A rotating shaft 10 is fixedly connected to the center of the bottom of the support frame 1. A rotating plate 11 is movably sleeved on the outside, and the other ends of two pull rods 9 are hinged to the two ends of the rotating plate 11. The guide rods 3 are moved by the moving plate 5. At this time, the guide rods 3 are guided by the guide groove 2, so that the two guide rods 3 at one end are brought closer to each other. The two guide rods 3 move laterally during the process of approaching each other. During the movement of the moving plate 5, one end of the pull rod 9 is pushed to move by the fixed shaft 8. The other end of the pull rod 9 pushes one end of the rotating plate 11 to rotate around the rotating shaft 10. The other end of the rotating plate 11 pulls one end of the other pull rod 9 to move. The other end of the pull rod 9 pulls another moving plate 5 to move, thereby driving the two guide rods 3 at the other end to move laterally. Under the guidance of the two guide grooves 2 at the other end, the two guide rods 3 at the other end are brought closer to each other.

[0029] Both ends of the bottom of the two movable plates 5 are provided with long through grooves 6. Two guide rods 3 at one end pass through the interior of the two long through grooves 6 respectively. During the movement of the movable plates 5, the guide rods 3 can move closer to each other inside the long through grooves 6 under the guidance of the guide grooves 2.

[0030] To facilitate the better reset of the two guide rods 3, a telescopic spring 7 is installed inside the long through groove 6. One end of the telescopic spring 7 is fixedly connected to one end of the long through groove 6, and the other end of the telescopic spring 7 is fixedly connected to the outside of the guide rod 3. When the two guide rods 3 move closer to each other inside the long through groove 6, the telescopic spring 7 is compressed by force. When the moving plate 5 is reset, the telescopic spring 7 can push the guide rod 3 to reset.

[0031] The bottom ends of the support frame 1 are fixedly connected to guide rails 15, and the two movable plates 5 are slidably connected to the outside of the two guide rails 15 respectively. Through the setting of the guide rails 15, the movable plates 5 can move stably at the bottom of the support frame 1.

[0032] Two positioning strips 17 are fixedly connected to the top of the support frame 1. The positioning strips 17 are located between two guide grooves 2 on one side. The positioning strips 17 can be used to position the width of the screen, ensuring that the device can fix screens of different lengths with the same width, thus improving the versatility of the device.

[0033] To ensure that the movable plate 5 moves synchronously, the drive assembly includes a fixed base 12, an electric push rod 13, and a fixed block 14. The fixed base 12 is fixedly connected to the bottom of the support frame 1. The electric push rod 13 is installed on one side of the fixed base 12. The fixed block 14 is fixedly connected to one side of the movable plate 5. The push rod end of the electric push rod 13 is fixedly connected to one side of the fixed block 14. The push rod of the electric push rod 13 drives the movable plate 5 to move at the bottom of the support frame 1. During the movement of the movable plate 5, the fixed shaft 8 pushes one end of the pull rod 9 to move. The other end of the pull rod 9 pushes one end of the rotating plate 11 to rotate around the rotating shaft 10. The other end of the rotating plate 11 pulls one end of another pull rod 9 to move. The other end of the pull rod 9 pulls another movable plate 5 to move. During this process, the two guide rods 3 at both ends can move synchronously.

[0034] Limiting rings 16 are fixedly sleeved on the outer bottom of the four guide rods 3. The top of the limiting rings 16 abuts against the bottom of the moving plate 5. By setting the limiting rings 16, the guide rods 3 can be limited, so that the guide rods 3 can move smoothly inside the long through groove 6.

[0035] The working principle or structural principle of the screen coating production is as follows: The screen is placed inside the two positioning strips 17, and then the electric push rod 13 is reset via a switch group. The push rod 13 drives the moving plate 5 to move at the bottom of the support frame 1 through the fixed block 14. The moving plate 5 then drives the guide rod 3 to move. At this time, guided by the guide groove 2, the two guide rods 3 at one end move closer to each other. During this process, the two guide rods 3 move laterally. During the movement of the moving plate 5, one end of the pull rod 9 is pushed by the fixed shaft 8 to move, and the other end of the pull rod 9... The rotating plate 11 is pushed to rotate around the rotating shaft 10. The other end of the rotating plate 11 pulls one end of another lever 9 to move. The other end of the lever 9 pulls another moving plate 5 to move, thereby driving the two guide rods 3 at the other end to move laterally. Under the guidance of the two guide grooves 2 at the other end, the two guide rods 3 at the other end move closer to each other. During this process, the two guide rods 3 at both ends can move synchronously to correct and position the screen and fix the screen, reducing the probability of error. Moreover, it can fix screens of the same width but different lengths, improving the versatility of the device.
