Abstract
Description
Technical Field
[0001] The utility model relates to a tool for producing a touch display screen, in particular to a tray for producing a touch display screen. Background Art
[0002] At present, in the production process of touch screens, materials such as touch panels and modules (referring to touch panels and display panels bonded together by OCA optical adhesive) are generally stored and circulated vertically on L-shaped racks. The structure of the L-shaped rack is as follows: Figure 1 As shown, in order to save space, the distance between adjacent materials is relatively small, but this also makes it easy for adjacent materials to collide when taking and placing materials.
[0003] In addition to the easy collision between adjacent materials, there is also the problem that when the module is placed upright on an L-shaped rack and placed in a degassing device, the membrane inside the LCD display panel is easily shifted in the upright state. Utility Model Content
[0004] In order to solve the technical problems that adjacent materials are prone to collision and the membrane inside the liquid crystal display panel is prone to displacement, the utility model provides a tray for the production of touch screen displays. The materials are placed flat on the tray, and the materials and the tray are stacked alternately. When taking and placing materials, adjacent materials will not collide with each other, and the space utilization rate is also relatively high.
[0005] The touch screen production tray provided by the present invention is used to store sheet materials used in the touch screen production process. When in use, the tray is placed horizontally, and the sheet materials are placed flat on the tray, avoiding the problem of membrane displacement inside the liquid crystal display panel caused by vertical placement. The tray has ventilation holes, a support structure, and a limiting structure. The support structure is used to support the sheet materials placed on the tray to prevent the sheet materials placed on the tray from blocking the ventilation holes of the tray from the top; the limiting structure is used to prevent the sheet materials placed on the other tray from blocking the ventilation holes of the tray from the bottom when the tray is stacked on another tray. When the modules are placed on the tray, the modules and the tray are stacked alternately, and placed in a debubbling device for debubbling, the ventilation holes can make the air pressure of different modules uniform.
[0006] Preferably, the tray includes a tray body and an anti-skid pad fixed to the upper side of the tray body, the anti-skid pad being used to prevent the sheet material from sliding horizontally relative to the tray. Those skilled in the art may, as needed, eliminate the anti-skid pad and design a limiting structure on the tray to prevent the sheet material from sliding horizontally relative to the tray.
[0007] Preferably, the tray body is made of ABS plastic with an integrated structure, which is heat-resistant to 80°C, has good toughness, is low-cost, and is anti-static. The anti-slip mat is made of heat-resistant silicone and is bonded to the tray body. Those skilled in the art may replace the tray body and anti-slip mat with other heat-resistant materials and change the connection method between the anti-slip mat and the tray body as needed. If the tray body material is not anti-static, an anti-static coating may need to be sprayed on the tray body, but this anti-static coating is prone to shedding.
[0008] Those skilled in the art can design the tray body into different structures as needed. For example, the tray body can be designed as a rectangular plastic sheet with an upwardly protruding annular area, so that a square annular boss is formed on the upper side of the rectangular plastic sheet, and a square annular groove is formed on the lower side of the rectangular plastic sheet. The limiting structure includes a square annular groove and a square annular boss. When the tray is stacked on another tray, the square annular boss of the other tray is inserted into the square annular groove of the tray, and the square annular groove gradually narrows toward the bottom of the groove. The square annular boss surrounds a storage groove for accommodating sheet materials. The bottom of the storage groove protrudes upward to form staggered supporting ridges. Anti-slip pads are provided on the upper side of the supporting ridges. The supporting structure includes supporting ridges and anti-slip pads. Ventilation holes are evenly distributed in the area of the bottom of the storage groove except for the supporting ridges. The tray body with this structure is easy to grasp and take, and is not easily deformed.
[0009] Preferably, the upper side of the supporting rib is recessed downward to form a ventilation groove, so that the air pressure at different positions of the same module is uniform.
[0010] Those skilled in the art can design the size of the storage groove as needed. For example, the storage groove can be designed to accommodate a 15.6-inch sheet material, or two 10.1-inch sheet materials placed side by side, so that the tray can be used to store and circulate sheet materials of different sizes - 15.6 inches and 10.1 inches.

[0019] The utility model will be further described in conjunction with the drawings and one embodiment of the utility model.
[0020] Figure 2 A perspective view of the tray according to one embodiment of the utility model. The tray has a vent hole 11, a support structure and a limiting structure. The support structure is used to support the sheet material placed on the tray, so as to prevent the sheet material placed on the tray from blocking the vent hole 11 of the tray from the upper side. The limiting structure is used to prevent the sheet material placed on another tray from blocking the vent hole 11 of the tray from the lower side when the tray is stacked on the another tray. The tray can be used for the storage and turnover of 15.6-inch (referring to the diagonal dimension of the visual area) and 10.1-inch (referring to the diagonal dimension of the visual area) sheet materials. One tray can place one 15.6-inch sheet material. In comparison Figure 3 and 4 , the placement of one 15.6-inch sheet material X on the tray can be understood. One tray can place two 10.1-inch sheet materials. The two 10.1-inch sheet materials are placed side by side, and the long side of the sheet material is opposite to the short side of the tray. In comparison Figure 3 and 8 , the placement of two 10.1-inch sheet materials Y on the tray can be understood.
[0021] The tray includes a tray body 1 and a non-slip pad 2 fixed on the upper side of the tray body 1. The tray body 1 is made of ABS plastic material and has an integral structure, which is resistant to 80℃ high temperature, has good toughness, low cost, anti-static and light weight. The structure of the tray body 1 is that a square ring-shaped area of a rectangular plastic sheet is upwardly protruded, so that a square ring-shaped boss 1a is formed on the upper side of the rectangular plastic sheet, and a square ring-shaped groove 1b is formed on the lower side of the rectangular plastic sheet. The tray body 1 is not easy to deform.
[0022] The square ring-shaped boss 1a surrounds a storage groove 1c for accommodating the sheet material. The groove bottom of the storage groove 1c is upwardly protruded to form staggered support edges 12. See Figure 3The anti-slip pad 2 is arranged on the upper side of the supporting edge 12 and is evenly distributed in the storage groove 1c. The supporting structure includes the supporting edge 12 and the anti-slip pad 2. The limiting structure includes a square ring groove 1b and a square ring boss 1a. Figure 5 and 6 When one pallet is stacked on another, the square ring-shaped boss of the lower pallet is inserted into the square ring-shaped groove of the upper pallet. The square ring-shaped groove gradually narrows toward the bottom of the groove, allowing air to flow from the vent of the upper pallet to the bottom of the upper pallet without being blocked by the sheet materials placed on the lower pallet.
[0023] The upper side of the supporting rib 12 is concave downward to form a ventilation groove 121. When the module is placed on the tray, the modules and the tray are alternately stacked, and placed in the debubbling equipment for debubbling, the ventilation groove 121 makes the air pressure at different positions of the same module uniform. Figure 3 The vent holes 11 are evenly arranged in the bottom area of the placement groove 1c except the supporting edge 12. When the modules are placed on the tray, the modules and the tray are alternately stacked and placed in the debubbling equipment for debubbling, the vent holes 11 make the air pressure of different modules uniform. Figures 5 to 7 You can understand the situation of 15.6-inch modules X and trays stacked alternately. When placed in the defoaming equipment for defoaming, the direction of the airflow is shown in Figure 7 .
[0024] The degassing equipment is used to remove bubbles between the touch panel and display panel, which are bonded together with OCA optical adhesive. Modules and trays are stacked alternately and placed in a degassing chamber. Air pressure is then injected (i.e., airflow is injected into the chamber to increase the pressure). Air pressure is continuously injected into the lower tray through the vent holes 11 and vent grooves 121 of the top tray. When the injected air pressure reaches production requirements, the modules can be continuously degassed. Because there are vent holes and spaces above and below the modules in the tray, air pressure can flow quickly downward, preventing air pressure blockage. Ultimately, different modules can be pressurized evenly and simultaneously.
[0025] The anti-slip mat 2 is made of high-temperature-resistant silicone and is bonded to the tray body 1. It is a rectangular silicone sheet whose upper surface contacts the sheet material. Static friction between the sheet material and the pad prevents the sheet material from sliding relative to the tray when the tray is tilted. A tilted tray is considered uneven, while a level tray is defined as a height direction h parallel to the direction of gravity g.
