Description

Technical Field

[0001] This utility model belongs to the field of dispensing technology and relates to a pressure-holding device for bonding a display panel and a structural frame. Background Technology

[0002] In existing technology, in-vehicle electronic display devices include glass and a frame. The glass is mounted on the frame using HVB double-sided adhesive, and the frame is made of aluminum. Double-sided adhesive needs to be applied to all four sides of the glass. This installation method leads to several problems: First, with double-sided adhesive applied to all four sides, the glass adheres tightly to the aluminum frame, and excessive stress can cause it to crack. Second, once the glass is attached to the frame, the only way to separate the glass and frame is through destructive means. Third, the double-sided adhesive occupies approximately 25-30mm of width, resulting in a relatively wide black border around the glass.

[0003] To address these issues, the current method involves applying adhesive to bond the glass and frame. This involves applying PUR adhesive to the frame, placing the glass on the frame, and then pressing it together using a pressure-holding fixture. However, this method is problematic because the frame of an automotive electronic display device is relatively large, the adhesive application process is lengthy, and the frame is made of metal, which is generally at a low temperature. This causes the PUR adhesive to solidify quickly and not spread out, resulting in reduced adhesion. Consequently, the bonded glass is uneven, has low stability, and may detach during use. Utility Model Content

[0004] (a) Purpose of the utility model The purpose of this invention is to provide a pressure-holding device for bonding a display panel to a structural frame, which uses a secondary heating and pressure-holding method to fully spread the PUR adhesive, thereby improving the bonding stability between the glass and the frame.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides a display panel and structural frame bonding and pressure-holding device, including: a pressure-holding fixture for pressing the glass and the frame together; and a base, a lower heating plate, an upper heating plate, and a lifting mechanism. The lower heating plate is disposed on the base and is used to support the pressure-holding fixture; the upper heating plate is disposed directly above the lower heating plate; and the lifting mechanism is disposed on the base and is used to drive the upper heating plate to rise and fall to provide pressure to the pressure-holding fixture.

[0006] Preferably, the lifting mechanism includes a guide component and a power component. The guide component is disposed on the base and is used to guide the upper heating plate to move in a vertical direction. The power component is disposed on the guide component, and the output end of the power component is connected to the upper heating plate to drive the upper heating plate to lift.

[0007] Preferably, the guide assembly includes a guide post fixedly connected to the base and a guide sleeve slidably connected to the guide post. The base is provided with multiple sets of guide posts and guide sleeves, and a lifting plate is fixedly connected between the multiple guide sleeves. The upper heating plate is connected to the bottom of the lifting plate.

[0008] Preferably, the upper heating plate is connected to the lifting plate by a screw.

[0009] Preferably, one end of the screw is fixedly connected to the upper heating plate, and the other end of the screw is threaded with a nut. The nut abuts against the top of the lifting plate. The lifting plate is provided with a through hole to allow the screw to move. An elastic element is connected between the upper heating plate and the lifting plate, and the elastic element is used to provide an elastic force acting on the upper heating plate.

[0015] (III) Beneficial Effects The display panel and structural frame bonding and pressure-holding device provided by the above technical solution initially presses the glass and frame together after adhesive bonding. Then, the pressure-holding fixture is moved to the lower heating plate, and the upper heating plate is moved downward by the lifting mechanism to hold the pressure-holding fixture. The upper and lower heating plates heat the upper and lower surfaces of the pressure-holding fixture respectively. The heat is transferred to the PUR adhesive dots between the glass and the frame, causing them to melt. This causes the PUR adhesive dots to spread out, thereby making the glass flat and stably bonded to the frame, preventing the glass from detaching from the frame during use.

[0017] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Reference Figures 1 to 3 As shown, the pressure-holding device for bonding the display panel and the structural frame in this embodiment includes a pressure-holding fixture 3, a base 1, a lower heating plate 2, an upper heating plate 4, and a lifting mechanism 5; the pressure-holding fixture is used to press the glass and the frame together; the lower heating plate 2 is disposed on the base 1; the upper heating plate 4 is disposed directly above the lower heating plate 2; the lifting mechanism 5 is disposed on the base 1, and the upper heating plate 4 is installed at the output end of the lifting mechanism 5. After the adhesive is applied, the glass and frame are initially pressed together using a pressure-holding fixture 3. Then, the pressure-holding fixture 3 is placed on the lower heating plate 2, and the upper heating plate 4 is moved downward by the lifting mechanism 5 to press against the pressure-holding fixture 3. The upper heating plate 4 and the lower heating plate 2 heat the upper and lower surfaces of the pressure-holding fixture 3 respectively. The heat is transferred to the PUR adhesive dots between the glass and the frame, causing them to melt and spread out. This allows the glass to be flat and stably bonded to the frame. During the above process, when the pressure reaches a certain force of 20 kg, the pressure heating is stopped, and the pressure is held for 10 minutes to improve the bonding effect.

[0019] In this embodiment, the lifting mechanism 5 includes a guide component 51 and a power component 52. The guide component 51 is disposed on the base 1 and is used to guide the upper heating plate 4 to move vertically. Specifically, the guide component 51 includes a guide post 511 fixedly connected to the base 1 and a guide sleeve 512 slidably connected to the guide post 511. The base 1 is provided with four sets of guide posts 511 and guide sleeves 512, which are fixed at the four corners of the base 1 and arranged in a rectangular pattern. A lifting plate 513 is fixedly connected to the four guide sleeves 512. The upper heating plate 4 is connected to the bottom of the lifting plate 513, that is, when the lifting plate 513 moves up and down with the guide sleeves 512 based on the guide posts 511, the upper heating plate 4 moves up and down with them.

[0020] The upper heating plate 4 is connected to the lifting plate 513 via a screw 515. Further, one end of the screw 515 is fixedly connected to the upper heating plate 4, and the other end of the screw 515 is threaded with a nut 517. The nut 517 abuts against the top of the lifting plate 513. The lifting plate 513 has a through hole to allow the screw 515 to move. An elastic element is connected between the upper heating plate 4 and the lifting plate 513. The elastic element provides an elastic force acting on the upper heating plate 4, allowing the screw 515 to move within the through hole, meaning the upper heating plate 4 can move relative to the lifting plate 513. When the upper heating plate 4 presses against the pressure-holding fixture 3, after contact with the pressure-holding fixture 3, the lifting plate 513 continues to move downwards, thus the elastic element provides a buffering and protective function.

[0021] In the above embodiment, four sets of screws 515 and elastic elements are rectangularly distributed around the connection point between the lifting plate 513 and the power component 52, thereby improving the stability of the structure. Furthermore, the elastic element is a spring 516, which is sleeved on the screw 515, with both ends of the spring 516 abutting against the upper heating plate 4 and the lifting plate 513 respectively. This structure facilitates installation and disassembly, reducing costs.

[0022] In this embodiment, the power component 52 is disposed on the guide component 51, and the output end of the power component 52 is connected to the upper heating plate 4 to drive the upper heating plate 4 to rise and fall. Specifically, the power component 52 includes a lifting motor 521 and an electrical control box 523. The lifting motor 521 is electrically connected to the electrical control box 523. A support plate 514 is fixedly installed on the top of the guide column 511. Both the lifting motor 521 and the electrical control box 523 are mounted on the support plate 514. The output end of the lifting motor 521 vertically penetrates the support plate 514 and is connected to the lifting plate 513. The use of the electrical control box 523 facilitates the operation of the lifting motor 521. When the lifting motor 521 is running, its output end moves in the vertical direction, thereby driving the lifting plate 513 to move up and down, and in turn driving the upper heating plate 4 to move up and down, so as to realize the pressurization work of the pressure holding fixture 3.

[0023] Furthermore, a pressure sensor 522 is provided between the lifting plate 513 and the output end of the lifting motor 521. The pressure output to the pressure holding fixture 3 can be observed through the pressure sensor 522, which facilitates operation by the staff.

[0024] In this embodiment, both the upper heating plate 4 and the lower heating plate 2 include a plate body and multiple heating tubes arranged inside the plate body. The multiple heating tubes are evenly distributed and heated uniformly. The heating tubes can be electric heating tubes and are electrically connected to the electrical control box 523. The electrical control box 523 controls the opening and closing of the heating tubes and the heating temperature.

[0025] The base 1 is provided with a linear guide rail 6, and the lower heating plate 2 is disposed on the linear guide rail 6. The lower heating plate 2 is slidably connected to the base 1 through the linear guide rail 6, so that the lower heating plate 2 can be slid out of the base 1, thereby facilitating the placement and removal of the pressure holding fixture 3.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
