[0044] In the field of display screen repair and recycling, after disassembling a display screen, OCA adhesive (Optically Clear Adhesive) will remain on the surface, requiring removal. Current methods for removing OCA adhesive primarily rely on manual removal. Operators lightly scrape the OCA film on the screen until it lifts up, then slowly peel it off. This method is prone to adhesive breaks, leaving residue on the screen; it is also laborious, time-consuming, and inefficient. Furthermore, frequent scraping when adhesive breaks can damage the glass, increasing repair costs and hindering subsequent recycling.

[0045] Based on this, in order to solve the above problems, this application designs an adhesive removal fixture. The object to be removed can be stably held on the support plate under the action of suction and pressure, ensuring the stability of the object to be removed during the adhesive removal operation. By heating with a heating plate, the OCA adhesive on the object to be removed softens after being heated, making it easier for the operator to peel off the OCA adhesive, improving the adhesive removal efficiency, effectively reducing the difficulty of the adhesive removal operation, and avoiding damage to the object to be removed.

[0046] refer to Figure 1 , Figure 2 , Figure 3 This application provides an adhesive removal fixture 100, which includes a base 1 and a heating support assembly 2 and a pressing assembly 3 stacked on the base 1. The heating support assembly 2 includes a heating plate 4 and a support plate 5 stacked on the base 1. The support plate 5 is used to support the object to be removed from the adhesive. The support plate 5 is provided with a plurality of vacuum holes 6 for adsorbing the object to be removed from the adhesive. The pressing assembly 3 includes a pressure plate 7 for pressing the object to be removed from the adhesive onto the support plate 5. The pressure plate 7 is movable along the thickness direction of the support plate 5. The base 1 is provided with a sliding assembly 8 connected to the pressing assembly 3. The sliding assembly 8 is configured to move the pressure plate 7 horizontally above the support plate 5.

[0047] Understandably, the adhesive removal fixture 100 of this application is used to assist operators in removing adhesive from the object to be removed, specifically a display screen, which can be, but is not limited to, computer displays, mobile phone displays, and tablet displays. When the display screen needs to be replaced or recycled, after the display screen is disassembled from the equipment, OCA adhesive will remain on the display screen. The adhesive removal fixture 100 of this application can locate the display screen and assist operators in removing the adhesive.

[0048] refer to Figure 2 The heating plate 4 and the support plate 5 are stacked on the base 1. After the heating plate 4 is heated, the heat can be effectively conducted to the heating plate 4, so that the display screen is heated evenly on the heating plate 4.

[0049] refer to Figure 1 , Figure 3 The specific adhesive removal process is as follows: The object to be removed is placed horizontally on the support plate 5. The support plate 5 is provided with vacuum holes 6. Using these vacuum holes 6, the base 1 can be connected to an external vacuum pump to perform vacuuming. The support plate 5 can generate suction at each vacuum hole 6, stably adsorbing the display screen onto the support plate 5. Then, the pressure plate 7 is adjusted to press the pressure plate 7 onto the display screen, stabilizing and limiting the position of the display screen. Further, the heating plate 4 is controlled to heat up. The OCA adhesive on the display screen softens after being heated, making it easier for the operator to peel off the OCA adhesive. When peeling adhesive from different positions on the display screen, the horizontal position of the pressure plate 7 is adjusted accordingly, so that the pressure plate 7 is close to the current peeling position. The display screen remains in a stable and static state on the support plate 5, ensuring the stability of the adhesive removal operation.

[0050] The adhesive removal fixture 100 of this application places the object to be removed on a support plate 5. The object is then adsorbed onto the support plate 5 through a vacuum hole 6. The position of the pressure plate 7 is adjusted to stably hold the object on the support plate 5. The object is held stably on the support plate 5 by the suction and pressure, ensuring the stability of the object during the adhesive removal operation. In addition, the OCA adhesive on the object is softened by the heating plate 4, making it easier for the operator to peel off the OCA adhesive, improving the peeling efficiency, effectively reducing the difficulty of the peeling operation, and avoiding damage to the object.

[0051] refer to Figure 1 , Figure 2 In some embodiments, a vacuum chamber (as shown in the figure) is formed inside the base 1, and the vacuum chamber is connected to the vacuum hole 6; and an air extraction interface 9 for connecting to the vacuum chamber is provided on the side wall of the base 1.

[0052] Understandably, the base 1 has an internal hollow structure to form a vacuum chamber, and each vacuum hole 6 on the support plate 5 is connected to the vacuum chamber; then the base 1 is connected to a vacuum pump through the air extraction interface 9 to perform vacuuming operation, and a negative pressure is formed in the vacuum chamber, so that the support plate 5 can generate an adsorption force at each vacuum hole 6, stably adsorbing the object to be degummed onto the support plate 5.

[0053] In some embodiments, a plurality of vacuum holes 6 are evenly arranged on the support plate 5. With the vacuum holes 6 evenly arranged, the support plate 5 can provide uniformly dispersed suction to the object to be degummed.

[0054] refer to Figure 1 In some embodiments, the object to be degummed is a display screen, which is equipped with a control circuit board; the support plate 5 is equipped with a clearance groove 10.

[0055] Specifically, some existing touch-screen displays have a control circuit board. After the display is disassembled, the control circuit board remains on the display and protrudes relative to it. A corresponding recess 10 is provided in the support plate 5 to accommodate the control circuit board. The display is placed on the support plate 5, and the control circuit board can be embedded in the recess 10, ensuring a smooth fit between the display and the support plate 5. This prevents any part of the display from warping, guaranteeing a vacuum adsorption effect.

[0056] In some embodiments, the recess 10 does not extend through the support plate 5, and the recess 10 is formed by the downward recessed portion of the support surface of the support plate 5.

[0057] Continue to refer to Figure 1 In some embodiments, the support plate 5 is a rectangular plate, and the clearance groove 10 is an L-shaped groove.

[0058] Specifically, the recess 10 is L-shaped, and the right angle of the recess 10 is set to one of the right angles closest to the support plate 5. Therefore, the operator can adjust the placement direction of the display screen on the support plate 5 according to the shape and size of the display screen and the position of the control circuit board, so that the display screen is properly placed on the support plate 5.

[0059] refer to Figure 2 , Figure 3 In some embodiments, the pressing assembly 3 further includes telescopic structures 11 respectively disposed on both sides of the pressure plate 7. The telescopic structure 11 includes a support rod 1101 vertically inserted through the pressure plate 7, and limiting plates 1102 respectively disposed on the upper and lower ends of the support rod 1101.

[0060] Understandably, support rods 1101 are respectively installed on both sides of the pressure plate 7, so that the pressure plate 7 can move smoothly up and down along the support rods 1101 on both sides and move stably; and limit plates 1102 are respectively provided at the upper and lower ends of the support rods 1101, which effectively limit the range of motion of the pressure plate 7 in the up and down adjustment and improve the structural stability.

[0061] The pressure plate 7 can press down on the support plate 5 under its own weight.

[0062] refer to Figure 2 , Figure 3 In some embodiments, the telescopic structure 11 further includes an elastic element 1103, which is disposed between the limiting plate 1102 at the top of the support rod 1101 and the pressure plate 7, and is configured to apply a downward elastic force to the pressure plate 7.

[0063] Specifically, an elastic element 1103 is provided between the limiting plate 1102 at the top of the support rod 1101 and the pressure plate 7. The elastic element 1103 can apply elastic force to the pressure plate 7. Then, when the pressure plate 7 presses the display screen onto the support plate, the pressure plate 7 can apply a stabilizing force to the display screen under the action of the elastic element 1103, and the display screen remains stable.

[0064] The elastic element 1103 can be a spring or a compression spring, which can be directly sleeved on the support rod 1101, making the connection convenient and quick.

[0065] refer to Figure 1 , Figure 3 In some embodiments, the sliding assembly 8 includes a slide rail 801 disposed on opposite sides of the support plate 5 and a slider 802 slidably disposed on the slide rail 801; a limiting plate 1102 disposed at the lower end of the support rod 1101 is connected to the slider 802.

[0066] Specifically, the slider 802 can slide along the slider 802, the limiting plate 1102 is connected to the slider 802, and then the pressure plate 7 can move and adjust in the horizontal direction along the slide rails 801 on both sides.

[0067] refer to Figure 1 In some embodiments, the support plate 5 is a rectangular plate, the pressure plate 7 extends along the width direction of the support plate 5, and the slide rail 801 extends along the length direction of the support plate 5.

[0068] Specifically, the pressure plate 7 spans across the support plate 5 along the width direction, and the pressure plate 7 can be moved and adjusted along the length direction of the support plate 5; thus, the pressure plate 7 can press the display screen located at any position on the support plate 5.

[0069] In some embodiments, a handle 701 is provided on the end face of the pressure plate 7 facing away from the support plate 5. That is, the upper end face of the pressure plate 7 is provided with a handle 701. When it is necessary to lift the pressure plate 7, the operation is simple: just grasp it and apply an upward force to the pressure plate 7 to overcome the elastic force of the elastic member 1103. The operation is simple.

[0070] In some embodiments, a flexible pad 702 is provided on the end face of the pressure plate 7 facing the support plate 5. That is, the flexible pad 702 is provided on the surface of the pressure plate 7 that is in contact with the display screen, so as to avoid direct hard contact between the pressure plate 7 and the display screen, and to effectively protect the display screen by means of the flexible pad 702, preventing the display screen from being damaged by excessive local stress. The flexible pad 702 can be, but is not limited to, sponge or silicone pad.

[0071] refer to Figure 2 In some embodiments, the base 1 is provided with a temperature control switch 401 for adjusting the heating plate 4.

[0072] Understandably, the base 1 is equipped with a circuit board that can control the heating plate 4, and the temperature control switch 401 is connected to the circuit board and exposed outside the base 1; the opening and closing of the heating plate 4 can be controlled by controlling the temperature control switch 401.

[0073] In some embodiments, the temperature control switch 401 is a knob, and the temperature of the heating plate 4 can be adjusted by turning the temperature control switch 401.

[0074] refer to Figure 1 In some embodiments, the base 1 is also provided with an emergency stop switch 12, which can cut off all power to the equipment to ensure safety during use.
