Description

Technical Field

[0001] This utility model relates to the field of touch screen processing technology, specifically to an OGS touch screen processing fixture. Background Technology

[0002] OGS touchscreen (One Glass Solution) is a technology that directly forms an ITO conductive film and sensor on protective glass, integrating the protective glass and touch sensor together to achieve dual functions.

[0003] OGS touchscreens require clamping with fixtures during processing to prevent screen misalignment and errors. However, existing devices typically use clamps to hold both ends of the screen. Since the screen is made of glass, this clamping method can lead to uneven stress and breakage during processing, increasing costs. Furthermore, once the screen is fixed, it is difficult to adjust the clamp angle, potentially causing operational inconvenience. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing fixed fixture screen being prone to uneven stress and breakage, and the inconvenience of angle adjustment, and to provide an OGS touch screen processing fixed fixture.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an OGS touch screen processing fixture, including a base, a fixing plate on the base, and fixing frames symmetrically arranged on the base. The fixing plate is rotatably disposed between the two fixing frames. The fixing plate has a hollow internal structure, and several air holes are arrayed on the upper and lower surfaces of the fixing plate. A vacuum pump is provided on one side of the fixing frame. A through hole is provided through the rotating shaft at one end of the fixing plate. An air pipe is connected to the vacuum pump. One end of the air pipe is connected to the fixing plate through the through hole. A driving component is provided on the fixing frame and connected to the rotating shaft on one side of the fixing plate. A positioning plate is fixed on the rotating shaft on the other side of the fixing plate. A positioning component for fixing the positioning plate is provided on the fixing frame near the positioning plate.

[0008] As an improvement: the fixed plate has symmetrical slots on one side, and slide rails are provided on both sides of the slots inside the fixed plate. A dustproof net is slidably mounted on the slide rails. The dustproof net is fixed to the fixed plate by bolts, and a sealing strip is fitted at the joint between the dustproof net and the slot. The dustproof net prevents the debris generated during processing from entering the interior of the fixed plate through the air holes. The dustproof net is detachable and can be removed for cleaning to ensure the adsorption effect.

[0009] As an improvement: the drive assembly includes a motor fixedly mounted on a fixed frame, the motor shaft passing through the fixed frame and connected to a first synchronous pulley, and the shaft at one end of the fixed plate passing through the fixed frame and connected to a second synchronous pulley. The first and second synchronous pulleys are connected by a synchronous belt. The motor drives the first synchronous pulley to rotate, and through the synchronous belt transmission, drives the second synchronous pulley to rotate, causing the fixed plate to flip.

[0010] As an improvement: the positioning disk has a plurality of positioning holes arranged in a circular array with the rotating shaft of the fixed plate as the center. The positioning component includes a positioning rod adapted to the positioning hole. The fixed frame near the positioning disk is provided with a sleeve. The positioning rod is inserted into the sleeve. After the driving component drives the fixed plate to complete the angle adjustment, the positioning rod is inserted into the positioning hole at the corresponding position to fix the position of the fixed plate and ensure the stability of the fixed plate during the processing.

[0011] As an improvement: the positioning rod is provided with a connecting plate, which slides inside the sleeve. A return spring is sleeved on the outside of the positioning rod. One end of the return spring is connected to the connecting plate and the other end is connected to the sleeve. The setting of the return spring allows the positioning rod to automatically return to its original position after adjustment by relying on the elasticity of the return spring itself.

[0012] As an improvement: the outer diameter of the air tube is smaller than the inner diameter of the through hole, and the air tube is connected to one side of the fixed plate through a rotary joint. The air tube is connected to the fixed plate through a rotary joint, and its diameter is smaller than the through hole, which ensures that the air tube will not rotate when the fixed plate rotates, thus avoiding the situation of the air tube self-winding.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. By providing air holes on both the upper and lower surfaces of the fixing plate, a vacuum pump generates negative pressure to fix and adsorb the screen onto the fixing plate, ensuring uniform force on the screen during processing, reducing breakage, and thus reducing processing costs. At the same time, the fixing plate can adsorb the screen on both sides, improving processing efficiency.

[0016] 2. The fixed plate is rotated and its angle is adjusted by the drive component to facilitate processing. The fixed plate is then fixed by the positioning component to ensure stability during processing. Attached Figure Description

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1

[0028] Combined with appendix Figure 1 , Figure 2As shown, an OGS touchscreen processing fixture includes a base 1, a fixing plate 2 on the base 1, and fixing frames 3 symmetrically arranged on the base 1. The fixing plate 2 is rotatably positioned between the two fixing frames 3. The fixing plate 2 has a hollow internal structure, and several air holes 4 are arrayed on the upper and lower surfaces of the fixing plate 2. A vacuum pump 5 is provided on one side of the fixing frame 3. A through hole is provided through the rotating shaft at one end of the fixing plate 2. An air pipe 6 is connected to the vacuum pump 5. One end of the air pipe 6 is connected to the fixing plate 2 through the through hole. A driving component is provided on the fixing frame 3 and connected to the rotating shaft on one side of the fixing plate 2. A positioning disk 7 is fixed on the rotating shaft on the other side of the fixing plate 2. A positioning component for fixing the positioning disk 7 is provided on the fixing frame 3 near the positioning disk 7.

[0029] Through the above structure, the vacuum pump 5 draws gas to reduce the air pressure inside the fixed plate 2, thereby creating a negative pressure between the air hole 4 and the screen being suctioned, so that the air hole 4 can firmly suction the screen. At the same time, the screen and the fixed plate 2 are subjected to uniform force. The drive component can drive the fixed plate 2 to rotate and adjust, and the position of the fixed plate 2 is ensured by the positioning component.

[0030] Combined with appendix Figures 2 to 5 As shown, the drive assembly includes a motor 12 fixedly mounted on a fixed frame 3. The motor 12's shaft passes through the fixed frame 3 and is connected to a synchronous pulley 13. One end of the fixed plate 2's shaft passes through the fixed frame 3 and is connected to a synchronous pulley 14. The synchronous pulley 13 and synchronous pulley 14 are connected by a synchronous belt 15. The positioning disk 7 has a plurality of positioning holes 16 arranged in a circular array with the fixed plate 2's shaft as the center. The positioning assembly includes a positioning rod 17 adapted to the positioning holes 16. A sleeve 18 is provided on the fixed frame 3 near the positioning disk 7. The positioning rod 17 is inserted into the sleeve 18. A connecting plate 19 is provided on the positioning rod 17. The connecting plate 19 slides within the sleeve 18. A return spring 20 is sleeved on the outside of the positioning rod 17. One end of the return spring 20 is connected to the connecting plate 19, and the other end is connected to the sleeve 18.

[0031] With the above structure, the motor 12 drives the synchronous pulley 13 to rotate, and through the synchronous belt 15, drives the synchronous pulley 14 to rotate, causing the fixed plate 2 to flip. After the drive assembly drives the fixed plate 2 to complete the angle adjustment, the positioning rod 17 is inserted into the positioning hole 16 at the corresponding position to fix the position of the fixed plate 2 and ensure the stability of the fixed plate 2 during the processing. The setting of the return spring 20 allows the positioning rod 17 to automatically return to its original position after adjustment by relying on the elasticity of the return spring 20 itself.

[0032] Example 2

[0033] Based on Example 1, and in conjunction with Appendix Figure 3 and Figure 6As shown, the fixing plate 2 has symmetrically arranged sockets 8 on one side. The fixing plate 2 has slide rails 9 on both sides of the sockets 8. A dustproof net 10 is slidably arranged on the slide rails 9. The dustproof net 10 is fixed to the fixing plate 2 by bolts. A sealing strip 11 is sleeved at the junction of the dustproof net 10 and the socket 8. The outer diameter of the air pipe 6 is smaller than the inner diameter of the through hole. The air pipe 6 is connected to one side of the fixing plate 2 through a rotary joint.

[0034] With the above structure, the dustproof net 10 prevents the debris generated during processing from entering the interior of the fixed plate 2 through the air hole 4. The dustproof net 10 is detachable and can be removed for cleaning, ensuring the adsorption effect. The air pipe 6 is connected to the fixed plate 2 through a rotary joint, and its diameter is smaller than the through hole, ensuring that the air pipe 6 will not rotate when the fixed plate 2 rotates, thus avoiding the situation where the air pipe 6 self-entangles.

[0035] The specific usage method is as follows:

[0036] Place the touch screen to be processed on the fixing plate 2, start the vacuum pump 5, and extract the air in the fixing plate 2 to form a negative pressure between the air hole 4 and the touch screen, thereby firmly adsorbing the touch screen and making the force even when fixing and clamping. The dustproof net 10 can prevent the debris generated during the processing from entering the vacuum pump 5 through the air hole 4 and causing damage to it.

[0037] If it is necessary to adjust the angle of the fixed plate 2, pull the positioning rod 17 towards the sleeve 18 so that the positioning rod 17 extends out of the positioning hole 16. Then start the motor 12, and the motor 12 drives the synchronous pulley 13. Through the synchronous belt 15, the fixed plate 2 is rotated to a suitable angle. Then, the positioning rod 17 is reinserted into the corresponding positioning hole 16 to ensure the stability of the fixed plate 2 during processing.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
