Description

Technical Field

[0001] This invention relates to the field of APR technology, and more particularly to an APR and its preparation method. Background Technology

[0002] With the development of science and technology, smart handheld electronic devices such as mobile phones and tablets are ubiquitous in our lives. Most of these devices use touch screens for data collection and recognition interaction. Existing APR plates, used as jigs for making insulating layers for large touch screen panels, have the following problems: it is difficult to apply force when installing and using APR plates, making it inconvenient to detect the applied pressure; the overall testing operation of APR plates is cumbersome; and APR plates easily lose their original performance after repeated installation, removal, debugging, and pressurization, which is not conducive to the reuse of APR plates. Therefore, an APR and its preparation method are proposed. Summary of the Invention

[0003] To address the technical problems of APR plates being difficult to apply force during installation and use, inconvenient to test the applied pressure, cumbersome overall testing operations, and prone to losing their original performance after repeated installation, disassembly, debugging, and pressurization, thus hindering their reuse, this invention provides an APR plate and its preparation method.

[0004] The present invention is achieved by the following technical solution: an APR and its preparation method, wherein the APR includes a base layer and a substrate, a high-density resin layer disposed on the base layer and the substrate, a pressure-sensitive layer disposed on the top of the substrate, a primitive area etched on the pressure-sensitive layer and extending to the substrate, and a wear-resistant layer coated on the pressure-sensitive layer and connected to the primitive area.

[0005] APR is prepared using the following steps:

[0006] S uses a coating device to spin-coat a pressure-sensitive layer on the top of the substrate;

[0007] S lays a protective layer with an etched pattern corresponding to the primitive area on top of the pressure-sensitive layer;

[0008] S etches, cleans, and dries the substrate with the protective layer laid on it;

[0009] After S-etching, a high-density resin layer is coated on the bottom of the substrate and bonded to the base layer;

[0010] After bonding, the protective layer is removed, and an abrasion-resistant coating is applied to the top of the pressure-sensitive layer.

[0011] The coating apparatus includes a spin coating component, a feeding mechanism located upstream of the spin coating component, a discharging mechanism located downstream of the spin coating component, a positioning and cleaning mechanism located at the top of the feeding mechanism, a lifting mechanism located at the bottom of the feeding mechanism, and a drying mechanism located at the top of the discharging mechanism.

[0012] Through the above technical solution, a high-density resin layer is connected between the base layer and the substrate of the APR. The high-density resin layer enhances the overall strength of the APR. A pressure-sensitive layer and a wear-resistant layer are coated on the surface of the APR. On the one hand, the pressure-sensitive properties of the pressure-sensitive layer can be used to determine the pressure state of the APR and the installation status of the APR based on the color change of the pressure-sensitive layer. On the other hand, the pressure-sensitive layer can be used to determine whether the local tension of the APR exceeds the standard or whether the local thickness of the APR is abnormal, which facilitates the inspection and installation of the APR. The wear-resistant layer enhances the wear resistance of the APR.

[0013] During the spin coating process, the cut and trimmed substrate is placed into the feeding mechanism, which then transports the substrate to the bottom of the positioning and cleaning mechanism. The positioning and cleaning mechanism positions the substrate. After that, the lifting mechanism picks up the positioned substrate and pushes it upwards. Then, the lifting and conveying mechanism starts to pick up the substrate from the bottom and transport it horizontally, so that the top of the substrate is cleaned by the positioning and cleaning mechanism to remove dust and foreign objects. The lifting and conveying mechanism transports the cleaned substrate into the spin coating assembly for spin coating.

[0019] As a further improvement to the above solution, the feeding mechanism includes a support frame fixedly connected to the spin coating component, two sets of parallel annular conveyor belts arranged inside the support frame, and a drive roller slidably sleeved on the inner ring of the conveyor belt.

[0025] 1. The APR of the present invention utilizes a high-density resin layer to enhance the overall strength of the APR. A pressure-sensitive layer and a wear-resistant layer are coated on the surface of the APR. On the one hand, the pressure-sensitive properties of the pressure-sensitive layer can be used to determine the pressure state of the APR and the installation state of the APR based on the color change of the pressure-sensitive layer.

[0063] Working principle:

[0064] First, a high-density resin layer is connected between the base layer and the substrate of the APR. The high-density resin layer enhances the overall strength of the APR. A pressure-sensitive layer and a wear-resistant layer are coated on the surface of the APR. On the one hand, the pressure-sensitive properties of the pressure-sensitive layer can be used to determine the pressure state of the APR and the installation status of the APR based on the color change of the pressure-sensitive layer. On the other hand, the pressure-sensitive layer can be used to determine whether the local tension of the APR exceeds the standard or whether there is any abnormality in the local thickness of the APR, which facilitates the inspection and installation of the APR. The wear-resistant layer enhances the wear resistance of the APR.

[0065] During the spin coating process, the cut and trimmed substrate is placed into the feeding mechanism 1. The feeding mechanism 1 transports the substrate to the bottom of the positioning and cleaning mechanism 4. The positioning and cleaning mechanism 4 performs a positioning operation on the substrate. Then, the lifting mechanism 5 picks up the positioned substrate and pushes it upward. After that, the lifting and conveying mechanism 7 starts to pick up the substrate from the bottom and transport it horizontally, so that the top of the substrate is cleaned by the positioning and cleaning mechanism 4 to remove dust and foreign objects from the top of the substrate. The lifting and conveying mechanism 7 transports the cleaned substrate into the spin coating assembly 3 for spin coating. After spin coating is completed, the lifting and conveying mechanism 7 transports the substrate into the unloading mechanism 2 and finally into the drying mechanism 6 to dry and complete the spin coating operation of the substrate.

[0066] During positioning, drive unit five is activated, causing the pressure plate to move downwards. At this time, the front positioning rod will block and position the conveyed substrate. Then, drive unit six is ​​activated, causing the two sets of clamping plates to move towards each other. The movable positioning rod positions the substrate from both sides. After positioning is completed, drive unit seven on lifting mechanism 5 is activated, pushing the inclined rod upwards. Then, suction cup two on top of the top rod two adsorbs the substrate from the bottom. After adsorption is completed, positioning and cleaning mechanism 4 returns to the initial position. Then, lifting mechanism 5 continues to lift the adsorbed substrate upwards without contacting the conveyor belt.

[0067] During the lifting and conveying process, the drive unit 72 of the lifting and conveying mechanism 7 starts and pushes the connecting plate 73 upward. At this time, the base 74 moves upward, causing the bearing plate 713 located at the top of the swing frame 76 to extend upward from the top of the box 31 along the rotating placement plate 33. When the swing frame 76 moves upward to the set position, that is, when it swings without interfering with the box 31 and the rotating placement plate 33, the drive unit 4 on the conversion unit 79 starts, then the rack moves, the gear rotates, and then the rotating shaft 75 fixed to the gear rotates. When the rotating shaft 75 rotates, the swing frame 76 moves upward to the feeder. One side of the structure 1 deflects, and at the same time, gear 1 drives gear 2 to rotate. At this time, gear 2 and gear 1 rotate in opposite directions. Then, shaft 2 77 rotates in the opposite direction to shaft 1 75. Under the drive of transmission unit 78, shaft 3 710 rotates in the opposite direction to shaft 1 75, thereby ensuring that when the swing frame 76 deflects, the bearing plate 1 713 is always in a horizontal state. Then, the bearing plate 1 713 is transported to the bottom of the substrate. After that, the suction cup 1 715 on the top of the suction unit 1 714 is adsorbed from the bottom of the substrate. Then, the lifting mechanism 5 returns to the initial position after the reverse steps of the adsorption process.

[0068] During substrate cleaning, drive unit three 72 and drive unit four are activated simultaneously, moving horizontally with the top of the substrate in contact with the wiping cloth at the bottom of the wiping cylinder as the reference point, wiping the top of the substrate. After wiping, the substrate is transported to the top of the two sets of contact rings 35 on the top of the rotating placement plate 33 inside the housing 31. Then, the exhaust pipe 39 draws air, putting the connecting cavity 37 under negative pressure. The substrate is then adsorbed between the two sets of contact rings 35. Then, drive unit two is activated, covering the top of the housing 31 with a cover plate for spin coating. Spin coating liquid is dripped from the dropper onto the top of the substrate. Drive unit one 34 is activated, causing the rotating plate to rotate... The placement plate 33 rotates, and the added spin coating liquid is spin coated onto the top of the substrate under centrifugal force. Then, the color of the top of the substrate is captured by a camera, and then the color recognition software installed in the controller is used to perform color recognition until the color of the top of the substrate reaches the set color. After that, the drive unit 34 is turned off to complete the spin coating. Then, the spin-coated substrate is transported to the lower feeding mechanism 2 using the above-mentioned feeding and unloading method. When transporting to the lower feeding mechanism 2, the drive unit 4 drives the rack to move in the opposite direction when picking up and unloading. Finally, the substrate is dried under the action of the drying mechanism 6.

[0069] This APR utilizes a high-density resin layer to enhance its overall strength. A pressure-sensitive layer and a wear-resistant layer are coated on the APR's surface. The pressure-sensitive layer's color change allows for determination of the APR's pressure state and installation status. It also helps determine if local tension or thickness is excessive, facilitating inspection and installation. The wear-resistant layer enhances the APR's abrasion resistance.

[0070] The APR preparation process includes loading, cleaning, spin coating, unloading, and drying of the APR pressure-sensitive layer. During spin coating, the top of the substrate is cleaned to prevent dust from remaining in the pressure-sensitive layer, thereby improving the spin coating quality and reducing the defect rate. The bottom suction and top spin coating method is adopted to reduce scratches and foreign dust entry caused by contact between the equipment and the top spin coating surface during the transportation process. The spin coating efficiency is high, the operation difficulty for operators is reduced, and the spin coating efficiency is improved.
