Description

Technical Field

[0001] This utility model relates to the field of flat panel processing technology, and in particular to a hot-melt pressure device for assembling liquid crystal flat panels. Background Technology

[0002] The LCD screen hot pressing process uses high temperature and high pressure to achieve the connection between the screen and the circuit board. In operation, the circuit board and screen to be pressed are placed on the pressure table of the hot pressing device for pressing.

[0003] However, in current hot pressing equipment, the pressing area is in an open state during the pressing process, and a lot of heat is lost into the air during the hot pressing process. Therefore, a longer holding time is required, resulting in energy waste.

[0004] To address this issue, we propose a hot-melt pressurization device for assembling LCD flat panels. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hot-melt pressurization device for assembling liquid crystal flat panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid crystal flat panel assembly hot melt pressurization device, comprising a worktable, a heat insulation cover, a back plate, a connecting column and a hot contact plate, wherein a pressure mold is installed on the upper surface of the worktable, the back plate is fixed on the upper surface of the worktable, a connecting column is lifted and lowered on the back plate, and a heat insulation cover is elastically slidably installed on the connecting column;

[0007] A pressure block is fixed to the lower surface of the connecting column, and a heat contact plate is fixed to the lower surface of the pressure block. The heat contact plate is located inside the heat insulation cover, and the lower surface of the heat insulation cover protrudes from the lower surface of the heat contact plate.

[0008] Preferably, a cylinder is fixed to the upper surface of the back plate by bolts;

[0009] The output end of the cylinder passes through the back plate and is fitted with a connecting plate, and a connecting post is fixed to the lower surface of the connecting plate.

[0010] A spring is movably sleeved on the connecting column, and the spring is located between the connecting plate and the heat insulation cover;

[0011] The original length of the spring is greater than the height of the connecting post.

[0012] Preferably, the lower surface of the pressure block is provided with a mounting groove, and an electric heating component is installed inside the mounting groove;

[0013] The heating element is in contact with the inner surface of the thermal contact plate.

[0014] Preferably, a support base is installed on the lower surface of the workbench;

[0015] There are four support bases in total, and the four support bases are arranged in a rectangular array on the lower surface of the workbench.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In use, the liquid crystal flat panel assembly hot melt pressurization device of this utility model can place the liquid crystal flat panel structure to be hot-pressed on the pressure mold and control the pressure block to move down by the cylinder.

[0018] During this process, the heat shield first contacts the surface of the pressure mold, thereby creating a relatively sealed environment between the pressure mold and the pressure block, and the liquid crystal flat panel structure to be pressed is in this environment.

[0019] At this time, the heating element generates heat. As the cylinder continues to operate, the pressure block drives the hot contact plate to work with the pressure mold to perform hot pressing on the LCD panel.

[0020] After hot pressing is completed, the pressure block moves away from the workpiece. At this time, the heat insulation cover automatically resets under the elastic force of the spring, thus facilitating the next hot pressing operation.

[0021] This invention ensures that the pressing area is relatively closed during the pressing process, which can concentrate the heat during the hot pressing process in the heat insulation cover, reduce the pressure holding time of subsequent workpieces, and avoid energy waste.

[0028] 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.

[0029] Example 1

[0030] like Figures 1-4 As shown, the present invention proposes a liquid crystal flat panel assembly hot melt pressurization device, including a worktable 1, a heat insulation cover 3, a back plate 4, a connecting column 10 and a hot contact plate 11. A pressure mold 6 is installed on the upper surface of the worktable 1, the back plate 4 is fixed on the upper surface of the worktable 1, the connecting column 10 is lifted and installed on the back plate 4, and the heat insulation cover 3 is elastically slidably installed on the connecting column 10.

[0031] A pressure block 9 is fixed to the lower surface of the connecting column 10, and a heat contact plate 11 is fixed to the lower surface of the pressure block 9. The heat contact plate 11 is located inside the heat insulation cover 3, and the lower surface of the heat insulation cover 3 protrudes from the lower surface of the heat contact plate 11.

[0032] Based on Example 1:

[0033] In the process of using the liquid crystal flat panel assembly hot melt pressurization device of this utility model, the liquid crystal flat panel structure to be hot-pressed can be placed on the pressure mold 6, and the pressure block 9 is controlled to move downward by the cylinder 5.

[0034] During this process, the heat insulation cover 3 first contacts the surface of the pressure mold 6, thereby creating a relatively sealed environment between the pressure mold 6 and the pressure block 9, and the liquid crystal flat panel structure to be pressed is in this environment.

[0035] At this time, the electric heating component 13 works to generate heat. As the cylinder 5 continues to work, the pressure block 9 drives the hot contact plate 11 to cooperate with the pressure mold 6 to perform hot pressing on the LCD panel.

[0036] After hot pressing is completed, the pressure block 9 moves away from the workpiece. At this time, the heat insulation cover 3 automatically resets under the elastic force of the spring 8, thus facilitating the next hot pressing operation.

[0041] A spring 8 is movably sleeved on the connecting column 10, and the spring 8 is located between the connecting plate 7 and the heat insulation cover 3.

[0042] The original length of spring 8 is greater than the height of connecting post 10. Through the design of the length of spring 8, it is ensured that spring 8 has sufficient elasticity to make heat insulation cover 3 automatically reset when the heat insulation cover 3 is not under force.

[0043] The lower surface of the pressure block 9 is provided with a mounting groove 12, and an electric heating component 13 is installed inside the mounting groove 12;

[0044] The heating element 13 and the inner surface of the hot contact plate 11 are in contact with each other. The heating element 13 generates heat when it works. As the cylinder 5 continues to work, the pressure block 9 drives the hot contact plate 11 to cooperate with the pressure mold 6 to perform hot pressing on the LCD panel.

[0045] A support base 2 is installed on the lower surface of the workbench 1;

[0046] There are four support bases 2 in total, and the four support bases 2 are arranged in a rectangular array on the lower surface of the workbench 1.
