However, some products cannot be reworked with the FPC and IC, and can only be scrapped, resulting in large product losses.

[0033] In order to solve the above technical problems, the technical solution of the utility model adopts a support platform to carry the liquid crystal panel, and adopts a first heating element and a second heating element to heat the area to be repaired of the liquid crystal panel. Specifically, the first heating element and the second heating element are respectively located on opposite sides of the support platform, so that the first heating element and the second heating element can heat both sides of the panel at the same time to repair the area to be repaired of the liquid crystal panel, thereby improving the repair effect. And because the liquid crystal panel is heated locally, the repair of FPC and IC can be avoided. At the same time, during the heating repair process, the position can also be adjusted to avoid the influence on the frame glue.

[0034] The above technical solution is described in detail below with reference to the accompanying drawings.

[0035] In the embodiment of the present utility model, Figure 1-Figure 2 As shown, the panel repair jig includes: a supporting platform 100, a first heating element 200 and a second heating element 300; in this embodiment, the panel to be repaired is a liquid crystal panel, wherein the supporting platform 100 is used to carry the liquid crystal panel to be repaired, and in a specific implementation process, the liquid crystal panel has an area to be repaired, and the first heating element 200 and the second heating element 300 are respectively arranged on opposite sides of the supporting platform 100, and heat the area to be repaired.

[0036] In the specific implementation process, it should be noted that the support platform 100 is placed horizontally, and the first heating element 200 and the second heating element 300 are connected to a temperature regulating device, so that the temperature of the first heating element 200 and the second heating element 300 can be adjusted to the corresponding temperature for different liquid crystal panels, and the temperature is set to the highest temperature, and the liquid crystal panel will not be damaged by exceeding the highest temperature during the heating repair process. In this embodiment, the repair jig also includes a support frame 700, and the support platform 100, the first heating element 200, and the second heating element 300 are all arranged on the support frame 700. The support frame 700 is made of metal material, preferably aluminum material, with high strength. The support frame 700 plays the role of fixed support, so that the support platform 100, the first heating element 200 and the second heating element 300 use the support frame 700 as a fulcrum to achieve the repair of the liquid crystal panel.

[0037] Furthermore, the repair jig also includes a driving component 400, which is connected to the first heating element 200 and / or the second heating element 300, and the driving component 400 drives the first heating element 200 and the second heating element 300 to move back and forth to approach and move away from the liquid crystal panel.

[0038] In this embodiment, the driving assembly 400 is installed on the support frame 700, wherein the driving assembly 400 can be a motor to drive the first heating element 200 and the second heating element 300 to move, or a cylinder to drive the first heating element 200 and the second heating element 300 to move, which is not limited in this embodiment. It can be understood that the driving assembly 400 drives one end of the first heating element 200 or the second heating element 300 to approach the support platform 100, and heats and repairs the area to be repaired of the liquid crystal panel on the support platform 100. The driving component 400 also drives the first heating element 200 or the second heating element 300 away from the supporting platform 100, and at this time the temperature of the first heating element 200 and the second heating element 300 is lower than the temperature when in the heating position, so as to save costs and facilitate placing the liquid crystal panel on the supporting platform 100 without causing damage to the liquid crystal panel. When the area to be repaired needs to be heated and repaired, the driving component 400 drives the first heating element 200 or the second heating element 300 to move from the standby position to the heating position, and the temperature of the first heating element 200 and the second heating element 300 increases when they move to the heating position, or, during the movement, the temperature of the first heating element 200 and the second heating element 300 increases, saving heating time.

[0039] In the specific implementation process, the first heating element 200 is arranged above the supporting platform 100, and the first heating element 200 heats the area to be repaired from the top surface of the liquid crystal panel. In this embodiment, one end of the first heating element 200 is fixed on the supporting frame 700, and the other end is arranged toward the supporting platform 100, and is used to heat and repair the liquid crystal panel.

[0040] Further, the driving assembly 400 includes a first driving member, the first heating member 200 includes a first heating end 210 and a first connecting end 220, the first connecting end 220 is connected to the first driving member, and the first heating end 210 is arranged near the supporting platform 100 and is used to heat the area to be repaired. In the specific implementation process, the first driving member is a cylinder, the cylinder is fixed on the supporting frame 700, and the telescopic rod of the cylinder is connected to the first heating member 200. Among them, the first heating member 200 includes a first heating end 210 and a first connecting end 220, the cylinder is connected to the first connecting end 220, and drives the first heating member 200 to approach and move away from the supporting platform 100. The first heating end 210 is used to generate heat and to heat the area to be repaired of the liquid crystal panel. In the specific implementation process, the first heating member 200 is made of metal material, preferably copper material, and the heating speed is fast. It can be understood that the temperature of the first heating end 210 of the first heating member 200 is the highest, and the temperature gradually decreases along the direction from the first heating end 210 to the first connecting end 220. It should be noted that the temperature of the first heating end 210 must meet the temperature required for repairing the liquid crystal panel.

[0041] Furthermore, after the liquid crystal panel is placed on the supporting platform 100, the first heating end 210 of the first heating element 200 is located above the area to be repaired, and the second heating end 310 of the second heating element 300 is located below the area to be repaired. In this embodiment, the first heating element 200 heats and repairs the area to be repaired from the top surface of the area to be repaired, and the second heating element 300 heats and repairs the area to be repaired from the bottom surface of the area to be repaired, so that both sides of the area to be repaired are heated at the same time, thereby improving the efficiency and effectiveness of the repair.

[0042] Furthermore, the driving assembly 400 also includes a second driving member, the second heating member 300 includes a second heating end 310 and a second connecting end 320, the second connecting end 320 is connected to the second driving member, and the second heating end 310 is arranged close to the supporting platform 100 and is used to heat the area to be repaired.

[0043] Specifically, the second driving member is drivingly connected to the second connecting end 320 of the second heating member 300 to drive the second heating member 300 to approach or move away from the support platform 100. The second driving member may also be a cylinder, and the second driving member is fixed on the support frame 700. The second heating end 310 of the second heating member 300 is located below the support platform 100 and is arranged toward the support platform 100. The second heating end 310 is used to generate heat and heat the area to be repaired to achieve the purpose of repair. The temperature of the second heating end 310 is the highest, and the temperature gradually decreases along the direction from the second heating end 310 to the second connecting end 320. The second heating member 300 is also made of metal, preferably copper, and has a fast heating speed. It should be noted that the temperature of the second heating end 310 must meet the temperature required to repair the liquid crystal panel.

[0044] Optionally, the support platform 100 is provided with an avoidance through hole 110, and the second heating element 300 heats the panel through the avoidance through hole 110. In this embodiment, the area to be repaired of the liquid crystal panel is at least partially located at the avoidance through hole 110. Specifically, the liquid crystal panel is placed on the support platform 100, and the area to be repaired is at least partially located at the avoidance through hole 110 without contacting the support platform 100. In this way, when the first heating element 200 and the second heating element 300 heat and repair the repair area, the heat will not be transferred to the support platform 100, and the heat transfer is also reduced to ensure the effect of heating and repairing, and the temperature of the support platform 100 will not rise to avoid affecting other areas of the liquid crystal panel, thereby improving the yield of the product. In the process of heating the area to be repaired, the heated area to be repaired does not contact the support platform, reducing the heat transfer, ensuring the effect of heating and repairing, and avoiding the influence of high temperature on other areas of the liquid crystal panel, thereby improving the yield of the product. In the specific implementation process, the contour of the avoidance through hole 110 can be any shape, the first heating element 200 and the second heating element 300 are arranged corresponding to the avoidance through hole 110, and the outer surface contours of the first heating element 200 and the second heating element 300 are adapted to the contour of the avoidance through hole 110.

[0045] Optionally, in the horizontal direction of the support platform 100, the outer peripheral surface of the first heating element 200 and / or the second heating element 300 is within the space formed by the side wall of the avoidance through hole 110, that is, the first heating element 200 and the second heating element 300 can pass through the avoidance through hole 110. It can be understood that the inner diameter of the avoidance through hole 110 is larger than the outer diameter of the first heating element 200 and the second heating element 300, so that the first heating element 200 and the second heating element 300 can pass through the avoidance through hole 110, and more importantly, it is convenient for heat dissipation.

[0046] Optionally, the first heating element 200 and / or the second heating element 300 are provided with convex corners 500, and the convex corners 500 are protrudingly arranged along the radial direction of the first heating element 200 and the second heating element 300. Figure 2 As shown, the first heating element 200 and the second heating element 300 are cylindrical structures, and the end edges of the two heating elements toward the support platform 100 protrude in their respective radial directions, so as to facilitate heating and repairing operations on a small area of ​​the area to be repaired.

[0047] Optionally, the repair jig further includes a timing device 600, which is in communication with the driving component 400. In the specific implementation process, the timing device 600 is convenient for controlling the operation of the first heating element 200 and the second heating element 300, and the heating repair operation time of each liquid crystal panel can be set. When the timing device 600 reaches the preset time, it generates a driving signal and transmits it to the driving component 400. The driving component 400 drives the first heating element 200 and / or the second heating element 300 away from the liquid crystal panel according to the driving signal to stop the heating repair. In this way, the heating repair is easily controlled to avoid overheating and scrapping.

[0048] Optionally, the support platform 100 is made of insulating material with high strength, and the support platform 100 also has good strength and heat resistance. In addition, the support platform 100 is paved with an antistatic layer to avoid static electricity, wherein the antistatic layer can be glass fiber cloth, etc., and can also be paved with Teflon, etc.
