Description

Technical Field

[0001] This utility model belongs to the field of foldable display technology, and in particular relates to a UTG support base plate for auxiliary double-sided coating. Background Technology

[0002] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0003] As the foldable display industry continues to develop, UTG and UFG are gradually becoming the mainstream directions for display cover glass. The performance requirements for UTG cover glass are also becoming increasingly stringent, so UTG coating has shifted from single-sided to double-sided coating. Currently, the double-sided coating method involves bonding the UTG to a supporting substrate, coating one side, cutting, and then peeling the product off the substrate and double-sided adhesive. This process is repeated, and while this method is less expensive, it affects the production efficiency and yield of double-sided coated products.

[0004] The challenge of double-sided coating lies in the fact that after coating one side of the UTG (Ultra-Glass Tank), the UTG needs to be separated and re-coated. This process severely impacts production efficiency and yield, making the optimization of double-sided coating technology paramount. Currently, single-sided coating primarily uses sheet substrates bonded with double-sided adhesive to fix the UTG for single-sided coating. However, peeling the coated product from the substrate and double-sided adhesive in the current process often results in glass breakage and spillage due to the strong adhesion between the coating and the adhesive.

[0005] CN218331300U - A support platform for UTG glass defect detection discloses a support platform for UTG glass defect detection, which includes: a platform, a feeding suction cup on the upper side of the platform, and a cloth filter layer on the upper side of the suction cup. The material of the cloth filter layer is selected from any one of nylon cloth, polyethylene cloth, denim cloth, Oxford cloth, cotton blend fabric, linen, linen blend fabric, silk cloth, rayon cloth, and spandex cloth, but it cannot solve the above-mentioned technical problems. Utility Model Content

This plate utilizes low-vacuum adsorption to replace the bonding effect of double-sided adhesive, achieving a controllable UTG fixation function. This controllable adsorption significantly reduces the risk of damage during the peeling process.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a UTG bearing base plate with auxiliary double-sided coating, having:

[0023] The markings in the above figures are all: Detailed Implementation

[0024] 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.

[0025] See Figures 1-3 A UTG support base plate for auxiliary double-sided coating has: an upper plate 1 and a lower plate 2. The first side of the upper plate 1 can adsorb the display cover plate, and the second side of the upper plate 1 can be connected to the first side of the lower plate 2. A vacuum hole 11 is provided on the upper plate 1 and penetrates through the upper plate 1. The vacuum hole 11 replaces the bonding effect of double-sided adhesive with low vacuum adsorption, which can reduce the adsorption force between UTG and the support base plate during the peeling process, so as to peel it off smoothly and greatly reduce the risk of damage.

[0026] Figure 1 The display shows the specific appearance of the finished base plate. The base plate is made of two metal sheets with a certain thickness and strength. One metal sheet has holes drilled in the UTG bonding area, and the other sheet has a large groove 21 cut out in the center area, as shown. Figure 2 The diagram shows the two panels that make up the base plate. When the two panels are joined together, they form an adsorption base plate with a certain internal space. Figure 3 This is a schematic diagram showing the specific layout of the vacuum hole 11 on the base plate.

[0027] A vacuum vent 3 is located on the lower plate 2 and is connected to the vacuum port 11. The vacuum vent 3 draws air from the vacuum port 11, creating a negative pressure. This low-vacuum adsorption replaces the bonding effect of double-sided adhesive, achieving a controllable UTG fixation function. This controllable adsorption significantly reduces the risk of damage during the peeling process.

[0028] The first side of the lower plate 2 is provided with a groove 21, which can be connected to the air extraction hole 3 and the vacuum hole 11. The air extraction hole 3 extracts air, creating a negative pressure in the groove 21. Through one groove 21, the negative pressure can be transmitted to all the vacuum holes 11. The low vacuum adsorption effect replaces the bonding effect of double-sided adhesive, realizing a controllable UTG fixing function.

[0029] The upper plate 1 is provided with a series of vacuum holes 11, all of which are connected to the groove 21. The multiple vacuum holes 11 make the adsorption effect more stable and reliable.

[0030] Vacuum holes 11 are arranged in groups, with each group of vacuum holes 11 arranged in an "H" shape; a series of vacuum hole groups 11 are evenly provided on the upper plate 1. The evacuation hole 3 is provided with a closed structure. The closed structure consists of multiple fan-shaped baffles. Figure 3The image shows the air extraction hole 3, which creates negative pressure inside the substrate. This air extraction hole 3 has an outwardly protruding airflow control device with multiple fan-shaped baffles. After the UTG is properly attached, air is extracted at the air extraction hole 3. The gas in the internal cavity of the substrate can push aside the baffles to create a negative pressure environment. When the extraction is complete, due to the mutual restriction between the baffles, the internal cavity of the substrate cannot form a gas passage with the external environment, thereby maintaining the UTG adsorption and fixation effect during the coating process. Ideally, the vacuum level should be set to less than -1 kPa.

[0031] The groove 21 is located around the perimeter of the lower plate 2. The groove 21 is a large plate structure that can connect with all the vacuum holes 11.

[0032] The upper sheet 1 and lower sheet 2 are made of metal. Compared with the process of using a base plate and double-sided adhesive, the coating generally has less adhesion to metal sheets than to double-sided adhesive. This makes it less likely for the coating to deform under stress and have a poor appearance when peeled off due to excessive adhesion between it and the supporting base plate.

[0033] It has the following advantages:

[0034] 1. Controllable UTG fixation reduces the risk of damage during the peeling process: In the current process, peeling the coated product from the base plate and double-sided adhesive can cause problems such as glass breakage and spillage due to the strong adhesion between the coating and the double-sided adhesive. This solution replaces the adhesive effect of double-sided adhesive with low-vacuum adsorption, which can reduce the adsorption force between UTG and the supporting base plate during the peeling process, making it easier to peel off and greatly reducing the risk of damage.

[0035] 2. The supporting base plate of this solution needs to be made of a metal sheet with a certain rigidity that can be made into fine vacuum holes. Compared with the base plate + double-sided adhesive process, the coating generally has less adhesion to the metal sheet than to the double-sided adhesive. This makes it less likely for the coating to deform under stress and have poor appearance when peeled off due to excessive adhesion between it and the supporting base plate.

[0036] 3. Although the load-bearing base plate of this solution is more expensive than the existing acrylic base plate + double-sided adhesive load-bearing method, the load-bearing base plate of this solution has a higher recycling capacity and is less likely to be damaged during the production process.

[0037] This solution aims to replace the UTG fixing effect of double-sided tape with low-vacuum adsorption, thereby simplifying the peeling process after coating and cutting. The key point is that the adsorption effect of UTG by the vacuum holes on the substrate can be controlled by the air pressure inside the substrate, thus achieving efficient peeling.

[0038] By adopting the above structure, a controllable UTG fixation function is achieved by replacing the bonding effect of double-sided adhesive with low-vacuum adsorption. This controllable adsorption function significantly reduces the risk of damage during the peeling process.
