Description

Technical Field

[0001] This utility model belongs to the field of touch screen manufacturing technology, and more specifically, it relates to an exposure machine structure for touch screen manufacturing. Background Technology

[0002] Currently, in the field of touchscreen manufacturing, a specific exposure process is involved. A specific light source shines through a photomask, altering the properties of the photoresist on it and transferring the pattern defined on the mask to the glass substrate surface of the touchscreen. In existing touchscreen manufacturing processes, the low humidity inside the exposure machine causes internal particles and glass powder to become airborne. During the interaction between the mask and the glass substrate, these internal particles adhere to the mask, forming fixed points. This leads to a batch of defective products produced during the glass exposure process, severely impacting production efficiency and costs.

[0003] Existing technology includes a device titled "Touchscreen Functional Film Exposure Machine" with publication number "CN219738002U". This technology discloses a touchscreen functional film exposure machine, belonging to the field of screen production equipment technology. It includes a frame with a conveyor belt, an exposure machine mounted on the side of the frame, a fixing block on the side of the exposure machine, a control panel on the side of the exposure machine, and a heat dissipation vent. This touchscreen functional film exposure machine, through the use of a bend groove and a sliding rod, allows the sliding plate to move forward when the sliding rod reaches the bend of the bend groove. This movement, via a sloping groove, drives the sliding rod horizontally along the bend groove. The sliding rod, through a support rod and a connecting rod, moves a suction cup and the product onto the conveyor belt. The suction cup places the product onto the conveyor belt, completing the loading process. This achieves automatic loading during functional film exposure, solving the problems of low efficiency and high labor costs associated with manual loading. Simultaneously, it ensures consistent loading position and accuracy, improving both production efficiency and precision.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple structure for an exposure machine used in touch screen manufacturing, which enables moisture to spread within the exposure machine, reduces the flying of particles and glass powder, improves product quality and production efficiency, and reduces production costs, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a structure for an exposure machine used in touch screen manufacturing. The exposure machine cavity is equipped with an upper guide wheel and a lower guide wheel. A humidification pipe is installed inside the exposure machine cavity, and multiple humidification ports are provided on the humidification pipe. The humidification pipe is connected to a humidifier located outside the exposure machine cavity through a connecting pipe.

[0008] The exposure machine cavity is equipped with a photomask, an exposure light source is provided on one side of the photomask, and an upper guide wheel and a lower guide wheel are provided on the other side of the photomask.

[0009] The humidification tube is horizontally arranged at a position higher than the top of the touch screen.

[0010] The exposure chamber has a glass inlet on one side and a glass outlet on the other side.

[0011] The photomask is fixedly mounted on a bracket inside the exposure machine cavity.

[0012] The upper guide wheel and the lower guide wheel are respectively provided with V-shaped grooves.

[0013] When the touch screen is exposed through the exposure chamber, the upper part of the touch screen is fitted into the V-groove of the upper guide wheel, and the lower part of the touch screen is fitted into the V-groove of the lower guide wheel.

[0014] The upper guide wheel is provided in multiple ways, and the upper drive chain is fitted on the upper driven teeth of the multiple upper guide wheels. The upper drive chain is also fitted on the upper drive teeth of the upper drive motor.

[0015] The lower guide wheel is provided in multiple ways, and the lower drive chain is fitted on the lower driven teeth of the multiple lower guide wheels. The lower drive chain is also fitted on the lower drive teeth of the lower drive motor.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The exposure machine structure for touch screen manufacturing described in this utility model includes upper and lower guide wheels inside the exposure machine cavity. These guide wheels are used to clamp and transport the touch screen, ensuring that the touch screen reliably passes through the exposure machine cavity for exposure processing. A humidification pipe is installed inside the exposure machine cavity, located near the top. The humidification pipe is connected to an ultrasonic humidifier located outside the exposure machine cavity via a connecting pipe. The ultrasonic humidifier is a compact, fast-responding, and uniformly humidifying component that can effectively supply moisture through the connecting pipe. The moisture is evenly sprayed out through multiple humidification ports on the humidification pipe, spreading throughout the exposure machine cavity 1. This improves the uniformity of humidity inside the exposure machine cavity, thereby effectively controlling the internal particles and glass powder from flying around. During the operation of the mask and the touch screen (glass substrate), it prevents internal particles from adhering to the mask and forming fixed points, improving the quality of product exposure processing, reducing the number of defective products, and effectively reducing production costs.

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0023] As attached Figure 1 - Appendix Figure 2As shown, this utility model is a structure for an exposure machine used in touch screen manufacturing. The exposure machine cavity 1 has an upper guide wheel 2 and a lower guide wheel 3. A humidification pipe 4 is installed inside the exposure machine cavity 1, and multiple humidification ports 5 are provided on the humidification pipe 4. The humidification pipe 4 is connected to a humidifier located outside the exposure machine cavity 1 via a connecting pipe 6. The humidifier can be an ultrasonic humidifier 7. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the structural design, an upper guide wheel 2 and a lower guide wheel 3 are installed inside the exposure machine cavity 1. The upper guide wheel 2 and the lower guide wheel 3 are used to clamp and transport the touch screen 10, ensuring that the touch screen reliably passes through the exposure machine cavity 1 for exposure processing. A humidification pipe 4 is installed inside the exposure machine cavity 1, located near the top. The humidification pipe 4 is connected to an ultrasonic humidifier 7 located outside the exposure machine cavity 1 via a connecting pipe 6. The ultrasonic humidifier 7 is a humidification component with a compact structure, fast response, and uniform humidity. It can effectively supply moisture through the connecting pipe 6. The moisture is evenly sprayed out through multiple humidification ports 5 on the humidification pipe 4, spreading throughout the exposure machine cavity 1, improving the uniformity of humidity inside the exposure machine cavity 1. This effectively controls the internal particles and glass powder from flying around. During the operation of the mask and the touch screen (glass substrate), it prevents internal particles from adhering to the mask and forming fixed points, improving the product exposure processing quality, reducing the number of defective products, and thus effectively reducing production costs. The exposure machine structure for touch screen manufacturing described in this utility model is simple in structure, enables the spread of moisture inside the exposure machine, reduces the flying of particles and glass powder, improves product quality and production efficiency, and reduces production costs.

[0024] A photomask 8 is installed inside the exposure machine cavity 1. An exposure light source 9 is installed on one side of the photomask 8, and an upper guide wheel 2 and a lower guide wheel 3 are installed on the other side of the photomask 8. In this structure, the photomask is arranged vertically, and the touch screen is arranged vertically and parallel to the photomask during exposure. The upper guide wheel 2 and the lower guide wheel 3 hold the touch screen in a vertical state and drive the touch screen to move or stop. After the touch screen 10 is driven to move to the position aligned with the photomask 9, the upper guide wheel 2 and the lower guide wheel 3 stop. The exposure light source and the photomask work together to complete the exposure of the touch screen, and then the touch screen continues to be transported away.

[0025] The humidifying tube 4 is horizontally positioned above the top of the touchscreen 10. In this structure, with the humidifying tube 4 at the top, the moisture delivered from the humidifying port reliably diffuses throughout the cavity from top to bottom.

[0026] The exposure chamber 1 has a glass inlet 11 on one side and a glass outlet 12 on the other side. In this structure, the glass inlet 11 is used to feed the touchscreen into the exposure chamber before exposure, and the glass outlet 12 is used to send the touchscreen out of the exposure chamber after exposure.

[0027] The photomask 8 is fixedly mounted on a bracket 13 inside the exposure machine cavity 1. In this structure, the bracket is used to fix the photomask, ensuring it is in a vertical position for reliable operation.

[0028] The upper guide wheel 2 and the lower guide wheel 3 are each provided with a V-groove 14. When the touch screen 10 is exposed through the exposure chamber 1, the upper part of the touch screen 10 is engaged in the V-groove 14 of the upper guide wheel 2, and the lower part of the touch screen 10 is engaged in the V-groove 14 of the lower guide wheel 3. In this structure, the V-grooves 14 of the upper guide wheel 2 and the lower guide wheel 3 are used to clamp the touch screen 10.

[0029] Multiple upper guide wheels 2 are provided, and an upper drive chain is fitted onto the upper driven teeth of the multiple upper guide wheels 2. The upper drive chain is also fitted onto the upper drive teeth of the upper drive motor. The above structure can realize the synchronous rotation and stop control of multiple upper guide wheels as needed.

[0030] Multiple lower guide wheels 3 are provided, and a lower drive chain is fitted onto the lower driven teeth of the multiple lower guide wheels 3. The lower drive chain is also fitted onto the lower drive teeth of the lower drive motor. The above structure can realize the synchronous rotation and stopping control of multiple lower guide wheels as needed.

[0031] The exposure machine structure for touch screen manufacturing described in this utility model includes an upper guide wheel 2 and a lower guide wheel 3 inside the exposure machine cavity 1. These guide wheels 2 and 3 are used to clamp and transport the touch screen 10, ensuring that the touch screen 10 can reliably pass through the exposure machine cavity 1 for exposure processing. A humidification pipe 4 is installed inside the exposure machine cavity 1, located near the top. The humidification pipe 4 is connected to an ultrasonic humidifier 7 located outside the exposure machine cavity 1 via a connecting pipe 6. The ultrasonic humidifier 7 is a humidification component. With its compact structure, fast response, and uniform humidity, the device effectively supplies moisture through the connecting pipe 6. The moisture is then evenly sprayed out through multiple humidification ports 5 on the humidification pipe 4, permeating the interior of the exposure chamber 1. This improves the uniformity of humidity within the chamber, effectively controlling the movement of internal particles and glass powder. During the operation of the mask and the touch screen (glass substrate), it prevents internal particles from adhering to the mask and forming fixed points, thereby improving the quality of product exposure and reducing the number of defective products, which in turn effectively reduces production costs.
