Description

Technical Field

[0001] This application relates to the technical field of LCD display module processing equipment, and in particular to a light-shielding adhesive application device with secondary pressure holding and reinforcement. Background Technology

[0002] LCM, or LCD display module, refers to an assembly that combines liquid crystal display devices, connectors, peripheral circuits such as control and drive circuits, PCB circuit boards, backlights, structural components, etc. The LCD display module used in mobile phones includes a backlight, LCD, and CG stacked in sequence. The backlight emits light to illuminate the LCD so that the mobile phone can display content. However, the CG also has a photosensitive hole to sense external light. Therefore, in order to prevent the light emitted from the LCD from the surrounding area from affecting the photosensitive hole, a light-shielding adhesive (UVT) is applied to the gap between the backlight and the LCD.

[0003] In related technologies, after the light-shielding adhesive is applied to the LCM, it needs to be pressed first, then the film needs to be peeled off, and then a second press is required to complete the application. There are two ways to apply the light-shielding adhesive: the first is to apply it to the front of the backlight, and the second is to apply it to the narrow edge of the backlight. When the UVT application equipment performs the first press, the operator first fixes the LCM in a predetermined position with a predetermined posture, and then squeezes the light-shielding adhesive through the pressing element to complete the first press.

[0004] Regarding the aforementioned technologies, since there are two methods of applying the light-shielding adhesive, the LCM will be in a horizontal or vertical position during the first magnetic pressing. Therefore, positioning elements with different structures are needed to maintain the LCM's position, which can easily lead to a low yield rate in the light-shielding adhesive application equipment. Summary of the Invention

[0005] In order to improve the processing yield of the light-shielding adhesive application equipment while adapting to two application methods, this application provides a light-shielding adhesive application equipment with secondary pressure reinforcement.

[0006] The light-shielding adhesive application device with secondary pressure reinforcement provided in this application adopts the following technical solution:

[0007] A device for applying light-shielding adhesive with secondary pressure reinforcement includes:

[0008] frame;

[0009] A fixed platform plate is hinged to the frame at one end. One side surface of the fixed platform plate is used to connect with the workpiece. The fixed platform plate can change the workpiece from a horizontal direction to a vertical direction. The end of the fixed platform plate near its hinge is set as a light-shielding rubber positioning area.

[0010] A flipping drive component is connected to the fixed platform plate;

[0011] The first pressure block is vertically slidably mounted on the frame and is used to press down the light-blocking adhesive.

[0012] The first pressure-holding drive mechanism is connected to the first pressure-holding block.

[0013] By adopting the above technical solution, before the first pressure holding process, the fixed platform plate is first made horizontal by flipping the drive mechanism. After the LCM is coated with light-shielding adhesive, the LCM is then fixed on the upper surface of the fixed platform plate, with the light-shielding adhesive positioned in the light-shielding adhesive positioning area. If the light-shielding adhesive is coated on the front of the LCM, the first pressure holding mechanism directly moves the first pressure holding block downward to press the light-shielding adhesive. If the light-shielding adhesive is coated on the narrow edge of the LCM, the fixed platform plate is turned vertical by flipping the drive mechanism, and then the first pressure holding mechanism and the first pressure holding block complete the light-shielding process. The pressing action of the adhesive allows the light-shielding adhesive application equipment to adapt to two types of light-shielding adhesive application methods. Compared to methods that use different positioning elements to hold the LCM in a horizontal or vertical position, this design has two advantages. First, the LCM is always fixed on the fixed platform plate when it is horizontal, so the initial positioning error of the LCM on the fixed platform plate is unique. Second, the fixed platform plate rotates around one end of itself, so the transformation error of the LCM from horizontal to vertical is also smaller. Thus, it can improve the processing yield of the light-shielding adhesive application equipment while adapting to two types of light-shielding adhesive application methods.

[0014] Preferably, the first pressure-holding block includes a mounting portion and a roller portion, the mounting portion being connected to the first pressure-holding drive mechanism; the roller portion is rotatably connected to the mounting portion, and the roller portion is used to roll and abut against the light-shielding adhesive; the first pressure-holding drive mechanism includes a pressure-holding lifting cylinder and a pressure-holding moving cylinder, the pressure-holding lifting cylinder being connected to the frame; the housing of the pressure-holding moving cylinder is connected to the piston rod of the pressure-holding lifting cylinder, the piston rod of the pressure-holding moving cylinder is connected to the mounting portion, and the pressure-holding moving cylinder is used to make the roller portion roll.

[0015] By adopting the above technical solution, when the first pressure-holding process is to be performed on the light-shielding adhesive, the first pressure-holding block is first moved down by the pressure-holding lifting cylinder until the roller part abuts against the light-shielding adhesive. Then, the first pressure-holding block is moved along the narrow side extension direction of the LCM by the pressure-holding moving cylinder. During this process, the roller part will roll and abut against the narrow side of the LCM. At the same time, the pressure-holding lifting cylinder and the pressure-holding moving cylinder can also control the pressure between the roller part and the light-shielding adhesive. Therefore, the light-shielding adhesive can be gradually pressed onto the LCM. Thus, after the first pressure-holding process is completed, the light-shielding adhesive can be more tightly adhered to the front or narrow side of the LCM.

[0016] Preferred options also include:

[0017] A fixed platform is mounted on the frame, and the upper surface of the fixed platform is used to connect with the workpiece;

[0018] A bending pressure block is provided on the frame, and the bending pressure block is used to abut against the narrow edge of the workpiece;

[0019] A bending drive is provided on the frame, and the bending drive is connected to the bending pressure block to allow the bending pressure block to slide horizontally;

[0020] A caulking block is mounted on the frame and is used to insert into the gap of the workpiece;

[0021] A caulking drive is mounted on the frame, and the caulking drive is connected to the caulking block to allow the caulking block to slide horizontally;

[0022] A Z-axis drive is mounted on the frame and is connected to the slit-sealing drive and the bending drive.

[0023] By adopting the above technical solution, after the first process is completed, the LCM is transferred to the fixed platform. If the light-shielding adhesive is pasted on the front of the LCM, the bending pressure block is first moved downward and closer to the LCM by the Z-axis drive and the bending drive, so that the light-shielding adhesive is bent to the narrow edge of the LCM by the bending pressure block. Then, the Z-axis drive moves the sealing block to a height that is horizontally opposite to the gap of the LCM. Then, the sealing drive inserts the sealing block into the gap of the LCM, thus completing the second pressure holding. This is also known as the bending and sealing process. In this case, the bending pressure block can be pressed against the front of the LCM by using the Z-axis drive and the bending drive. If the light-blocking adhesive is pasted on the narrow edge of the LCM, the sealing block is first moved to a height that is horizontally opposite to the gap of the LCM by using the Z-axis drive. Then, the sealing block is inserted into the gap of the LCM by using the sealing drive, thus completing the second pressure holding (also known as sealing) process. In this case, the bending pressure block can be pressed against the narrow edge of the LCM by using the Z-axis drive and the bending drive.

[0024] Preferably, the upper surface of the fixed platform is used to adsorb the workpiece, a vacuum pressure valve is provided on the fixed platform, and the end of the fixed platform near the bending pressure block is set as a secondary working area; the fixed platform is provided with an X-axis positioning component, a Y-axis positioning component, and an avoidance drive component, the X-axis positioning component is used to abut against the edge of the workpiece adjacent to the secondary working area; the Y-axis positioning component is used to abut against the edge of the workpiece located in the secondary working area; the avoidance drive component is connected to the Y-axis positioning component, and the avoidance drive component is used to make the Y-axis positioning component move vertically.

[0025] By adopting the above technical solution, since the sealing block requires high positional accuracy of the LCM when inserted into the gap, the workpiece is first placed in a weak adsorption state by a vacuum pressure valve when the LCM is placed on the fixed table. Then, the X-axis positioning component calibrates the LCM in the X direction, and the Y-axis positioning component calibrates the LCM in the Y direction. During the Y-axis calibration, the Y-axis positioning component needs to be moved up to the height corresponding to the LCM by the avoidance drive component. At the same time, after the position calibration, the Y-axis positioning component is moved down to avoid the subsequent bending and sealing block. After the X-axis and Y-axis position calibration is completed, the workpiece is placed in a strong adsorption state by the vacuum pressure valve, thus completing the positioning calibration of the workpiece on the fixed table. In addition, this design method can also appropriately raise the LCM by the Y-axis positioning component and the avoidance drive component during the X-axis position calibration to weaken the adsorption force of the fixed table on the LCM, so it is also convenient to make large-scale X-axis position adjustments of the LCM.

[0026] Preferably, the frame is provided with an X-axis drive member, which is connected to the Z-axis drive member so that the Z-axis drive member moves along the X-axis. When the bending block abuts against the narrow edge of the workpiece and the slit block is inserted into the gap of the workpiece, the X-axis drive member is used to make the bending block and the slit block move in the opposite direction to the action direction of the X-axis positioning component.

[0027] By adopting the above technical solution, after the bending pressure block abuts against the front or narrow edge of the LCM, the bending pressure block can be made to move in the opposite direction of the X-axis positioning component by the X-axis driving component, so that the light-shielding adhesive can be moved and pressed after bending. Similarly, after the caulking block is inserted into the gap of the LCM, the caulking block can also be made to move in the opposite direction of the X-axis positioning component, so that the light-shielding adhesive can be moved and squeezed after being inserted into the gap of the LCM, thereby improving the adhesion tightness between the light-shielding adhesive and the LCM, and thus improving the processing yield of the bonding equipment.

[0028] Preferably, the surface of the bending block that abuts against the workpiece is a pressure-holding bending surface, which is L-shaped. One surface of the pressure-holding bending surface abuts against the front of the workpiece, and the other surface abuts against the narrow edge of the workpiece.

[0029] By adopting the above technical solution, when the light-shielding adhesive is pasted on the front side of the LCM and a second pressure-holding process is required, the bending pressure block can simultaneously abut against the front side and the narrow edge of the LCM when bending the light-shielding adhesive to the narrow edge of the LCM. Therefore, the portion of the light-shielding adhesive on the front side of the LCM can be pressure-held again, thereby improving the processing yield of the bonding equipment through a simpler operation. In addition, with this design, when the bending pressure block moves in the opposite direction to the X-axis positioning component, there will be no situation where air bubbles on one side of the light-shielding adhesive are squeezed to the adjacent side.

[0030] Preferably, the caulking block includes a fixing part, a rotating shaft part, an insertion part, and a return spring. The fixing part is connected to the caulking drive; the rotating shaft part is connected to the fixing part; one end of the insertion part is rotatably sleeved on the rotating shaft part, and the other end is used to insert into the gap of the workpiece; one end of the return spring is connected to the fixing part, and the other end is connected to the insertion part. After the insertion part leaves the workpiece, the return spring is used to reset the insertion part to its initial position.

[0031] By adopting the above technical solution, since the relative position between the caulking block and the LCM will be incorrect when the caulking drive component drives the caulking block to move, after the insertion part is inserted into the gap of the LCM, the insertion part will rotate around the rotating shaft by a predetermined angle to adapt to the relative posture between the LCM and the caulking block. As a result, the caulking block can tightly insert the light-shielding adhesive into the gap of the LCM, which helps to improve the processing yield of the bonding equipment. In addition, with this design, when the caulking block moves in the opposite direction to the action direction of the X-axis positioning component, the caulking block can also be smoothly pulled out from the gap of the LCM, thereby improving the processing yield and the processing smoothness of the bonding equipment.

[0032] Preferably, the frame is further provided with a Y-axis drive member, which is connected to the X-axis drive member to make the X-axis drive member move along the Y-axis. The direction of action of the Y-axis drive member is the same as the direction of action of the bending drive member and the slit-sealing drive member. During the second pressure holding process, the bending block and the slit-sealing block are first moved by the Y-axis drive member.

[0033] By adopting the above technical solution, the Y-axis drive can be selected as a large-stroke, low-precision component, while the bending drive and the caulking drive can be selected as small-stroke, high-precision components. When the second pressure holding process is to be performed, the bending block and the caulking block are first moved significantly closer to the LCM by the Y-axis drive. Then, the bending block and the caulking block are moved in the Y direction by the bending drive and the caulking drive respectively, thereby improving the processing efficiency and yield of the bonding equipment at the same time.

[0034] Preferably, the X-axis drive, the Y-axis drive, and the Z-axis drive are in the form of a lead screw slide; the bending drive and the caulking drive are in the form of a pressure-holding cylinder.

[0035] By adopting the above technical solution, on the one hand, since the part of the light-blocking adhesive on the front of the LCM has already undergone one pressure test during the second pressure test, when the front of the LCM is repeatedly pressure tested by the Z-axis drive, there is no need to specially control the downward pressure of the bending pressure block. Therefore, the structure of the Z-axis drive is selected as a lead screw slide. On the other hand, since the increase in pressure during the processing of the bending pressure block and the sealing block needs to be specially controlled, the structure of the pressure-holding cylinder is directly selected, which makes the structure of the bonding equipment simpler.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. By setting up the frame, fixed platform plate, flipping drive component, first pressure holding block and first pressure holding drive mechanism, on the one hand, the LCM is fixed on the fixed platform plate when it is horizontal, so the initial positioning error of the LCM on the fixed platform plate is unique; on the other hand, the fixed platform plate rotates around one end of itself, so the transformation error of the LCM from the horizontal direction to the vertical direction will also be smaller, thereby improving the processing yield of the light-shielding adhesive application equipment while adapting to two methods of applying light-shielding adhesive.

[0038] 2. By using the first pressure-holding block, which includes an mounting part and a roller part, and the first pressure-holding drive mechanism, which includes a pressure-holding lifting cylinder and a pressure-holding moving cylinder, the roller part will roll and abut against the narrow edge of the LCM. At the same time, the pressure-holding lifting cylinder and the pressure-holding moving cylinder can also control the pressure between the roller part and the light-shielding adhesive. Therefore, the light-shielding adhesive can be gradually pressed onto the LCM. Thus, after the first pressure-holding process is completed, the light-shielding adhesive can be more tightly adhered to the front or narrow edge of the LCM. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0045] This application discloses a device for applying light-shielding adhesive with secondary pressure reinforcement. (Refer to...) Figure 1 and Figure 2 The UVT bonding equipment with secondary pressure reinforcement includes a frame 1, a fixed platform plate 2, a flipping drive component 3, a first pressure holding block 4, and a first pressure holding drive mechanism 5. The fixed platform plate 2 is a thin cuboid shape. One end of the fixed platform plate 2 is hinged to the frame 1, and one side surface of the fixed platform plate 2 is fixed to the LCM by vacuum adsorption so that the LCM can be changed from the horizontal direction to the vertical direction. Moreover, the end of the fixed platform plate 2 near its hinge is set as the light-shielding adhesive positioning area 21. Therefore, when the LCM is fixed on the fixed platform plate 2, the light-shielding adhesive will be in the light-shielding adhesive positioning area 21.

[0046] Reference Figure 1 and Figure 2 The flip drive 3 is mounted on the frame 1. The flip drive 3 is a cylinder. The housing of the flip drive 3 is hinged to the frame 1. The piston rod of the flip drive 3 is hinged to the surface of the fixed platform plate 2 away from the LCM. The rotation of the fixed platform plate 2 can be achieved by extending and retracting the piston rod of the flip drive 3. The first pressure holding block 4 is vertically slidably mounted on the frame 1. The first pressure holding block 4 is located above the light-shielding adhesive positioning area 21. The first pressure holding block 4 and the light-shielding adhesive positioning area 21 are vertically opposite each other so that the first pressure holding block 4 can press down the light-shielding adhesive. The first pressure holding drive mechanism 5 is mounted on the frame 1 and is connected to the first pressure holding block 4.

[0047] Reference Figure 1 and Figure 2 Before the first pressure holding process, the fixed platform plate 2 is first made horizontal by flipping the drive unit 3. After the LCM is coated with light-shielding adhesive, the LCM is then fixed on the upper surface of the fixed platform plate 2, with the light-shielding adhesive positioned in the light-shielding adhesive positioning area 21. If the light-shielding adhesive is applied to the front of the LCM, it is pressed by the first pressure holding drive mechanism 5 and the first pressure holding block 4. If the light-shielding adhesive is applied to the narrow edge of the LCM, the fixed platform plate 2 is turned vertical by flipping the drive unit 3, and then the first pressure holding drive mechanism 5 and the first pressure holding block 4 are pressed. Block 4 completes the pressing of the light-shielding adhesive. Compared with the method of holding the LCM in a horizontal or vertical position by using different positioning elements, this design has the following advantages: First, the LCM is fixed on the fixed platform plate 2 when it is horizontal, so the initial positioning error of the LCM on the fixed platform plate 2 is unique. Second, the fixed platform plate 2 rotates around one end of itself, so the transformation error of the LCM from the horizontal to the vertical direction is also smaller. Thus, it can improve the processing yield of the light-shielding adhesive application equipment while adapting to two methods of applying the light-shielding adhesive.

[0048] Reference Figure 1 and Figure 2 In this embodiment, the first pressure-holding block 4 includes a mounting part 41 and a roller part 42, wherein the mounting part 41 is connected to the first pressure-holding drive mechanism 5; the roller part 42 is cylindrical in shape and is rotatably connected to the mounting part 41, and can roll and abut against the light-blocking adhesive; the first pressure-holding drive mechanism 5 includes a pressure-holding lifting cylinder 51 and a pressure-holding moving cylinder 52, the housing of the pressure-holding lifting cylinder 51 is fixedly connected to the frame 1, and the pressure-holding lifting cylinder... 51 is located above the fixed platform plate 2; the housing of the pressure-holding moving cylinder 52 is connected to the piston rod of the pressure-holding lifting cylinder 51, and the piston rod of the pressure-holding moving cylinder 52 is connected to the mounting part 41. The roller part 42 can be made to abut against the light-shielding adhesive by the pressure-holding lifting cylinder 51, and the roller part 42 can be made to roll along the narrow side extension direction of the LCM by the pressure-holding moving cylinder 52. Therefore, the light-shielding adhesive can be pressed tightly onto the LCM little by little, so that it can be tightly pasted on the front or narrow side of the LCM.

[0049] Reference Figure 1 and Figure 3 After the first pressure holding process is completed, the light-shielding adhesive application equipment will first peel off the film and then perform the second pressure holding process. The following settings are made for the second pressure holding process: First, a fixed platform 6 is set on the frame 1. Specifically, the fixed platform 6 is fixedly installed on the frame 1, and the upper surface of the fixed platform 6 is fixed to the LCM by vacuum adsorption. When the LCM is fixed on the fixed platform 6, one end of the LCM will be exposed outside the upper surface of the fixed platform 6, so that the area of ​​the fixed platform 6 near the exposed end of the LCM forms a secondary working area 62. At the same time, in this embodiment, because the second pressure holding process requires high positional accuracy of the LCM on the fixed platform 6, the fixed platform 6 is equipped with a vacuum pressure valve 61, an X-axis positioning component 63, a Y-axis positioning component 64, and an avoidance drive component 65. When the X-axis positioning component 63, the Y-axis positioning component 64, and the avoidance drive component 65 are required, the vacuum pressure valve 61 will first reduce the adsorption force on the LCM.

[0050] Reference Figure 1 and Figure 3The X-axis positioning component 63 is connected to a cylinder and a piston rod, and it abuts against the edge of the LCM adjacent to the secondary working area 62 to calibrate the LCM's position in the X direction. The Y-axis positioning component 64 has the same structure as the X-axis positioning component 63, but it abuts against the edge of the LCM located in the secondary working area 62 to calibrate the LCM's position in the Y direction. The avoidance drive component 65 is a cylinder, and the avoidance drive... The piston rod of component 65 is connected to the Y-axis positioning assembly 64, and the extension and retraction direction of the piston rod of the avoidance drive component 65 is the Z-axis. When the Y-axis positioning assembly 64 is needed, the piston rod of the avoidance drive component 65 extends to raise the Y-axis positioning assembly 64 to the height corresponding to the LCM. After the Y-axis positioning assembly 64 is used, the piston rod of the avoidance drive component 65 retracts so that the Y-axis positioning assembly 64 does not obstruct the LCM at one end of the secondary working area 62, thereby enabling the subsequent second pressure holding process.

[0051] Reference Figure 1 Secondly, the frame 1 is equipped with a Y-axis drive 13, an X-axis drive 12, and a Z-axis drive 11. Specifically, the Y-axis drive 13, X-axis drive 12, and Z-axis drive 11 are all in the form of a lead screw slide. The frame of the Y-axis drive 13 is fixedly connected to the frame 1. The X-axis drive 12 is connected to the slide of the Y-axis drive 13 so that the X-axis drive 12 can move in the Y direction. The Z-axis drive 11 is connected to the slide of the X-axis drive 12 so that the Z-axis drive 11 can move in both the X and Y directions, thus forming the power source for the required processing actions in the second pressure holding process.

[0052] Reference Figure 1 and Figure 4 Thirdly, the bonding equipment also includes a bending pressure block 7, a bending drive component 71, a sealing block 8, and a sealing drive component 81. Specifically, the bending pressure block 7 is connected to the slide of the Z-axis drive component 11 through the bending drive component 71. The bending drive component 71 is a pressure-holding cylinder, and its direction of action is parallel to the Y-axis. The sealing block 8 is connected to the slide of the Z-axis drive component 11 through the sealing drive component 81. The sealing drive component 81 is also a pressure-holding cylinder, and its direction of action is also parallel to the Y-axis, but the height of the sealing block 8 is lower than that of the bending pressure block 7.

[0053] Reference Figure 1 and Figure 4When the LCM is transferred to the fixing platform 6, if the light-shielding adhesive is pasted on the front of the LCM, the bending pressure block 7 and the caulking block 8 are first moved to a predetermined position close to the LCM by the Y-axis drive member 13. Then, the bending pressure block 7 is moved downward and close to the LCM by the Z-axis drive member 11 and the bending drive member 71 to bend the light-shielding adhesive to the narrow edge of the LCM. Then, the caulking block 8 is moved to a height that is horizontally opposite to the gap of the LCM by the Z-axis drive member 11. Then, the caulking block 8 is inserted into the gap of the LCM by the caulking drive member 81, thus completing the second pressure holding (also known as bending and caulking) process. At the same time, the bending pressure block 7 can also be pressed against the front of the LCM by the Z-axis drive member 11 and the bending drive member 71 to perform an additional pressure holding process.

[0054] Reference Figure 1 and Figure 4 If the light-blocking adhesive is pasted on the narrow edge of the LCM, the Y-axis drive 13 is used to move the sealing block 8 to a predetermined position close to the LCM. Then, the Z-axis drive 11 is used to move the sealing block 8 to a height that is horizontally opposite to the gap of the LCM. Then, the sealing block 8 is inserted into the gap of the LCM by the sealing drive 81, thus completing the second pressure holding (also known as sealing) process. At the same time, in this case, the Z-axis drive 11 and the bending drive 71 can also be used to press the bending pressure block 7 against the narrow edge of the LCM.

[0055] Reference Figure 3 and Figure 4 In this embodiment, after the bending pressure block 7 abuts against the front or narrow edge of the LCM, the bending pressure block 7 can be made to move in the opposite direction to the action direction of the X-direction positioning component 63 by the X-direction driving component 12. Therefore, the light-shielding adhesive can be moved and pressed after bending. Similarly, after the slugging block 8 is inserted into the gap of the LCM, the slugging block 8 can also be made to move in the opposite direction to the action direction of the X-direction positioning component 63. Therefore, the light-shielding adhesive can also be moved and squeezed after being inserted into the gap of the LCM. In summary, the adhesion tightness between the light-shielding adhesive and the LCM can be improved, which helps to improve the processing yield of the bonding equipment.

[0056] Reference Figure 1 and Figure 4In this embodiment, the surface of the bending block 7 that abuts against the LCM is designated as a pressure-holding bending surface 72. Specifically, the pressure-holding bending surface 72 is L-shaped. One inner surface of the pressure-holding bending surface 72 abuts against the front of the LCM, and the other inner surface abuts against the narrow edge of the LCM. When the light-shielding adhesive is pasted on the front of the LCM and a second pressure-holding process is required, when the bending block 7 bends the light-shielding adhesive to the narrow edge of the LCM, the bending block 7 can simultaneously abut against both the front of the LCM and the narrow edge. Therefore, the portion of the light-shielding adhesive on the front of the LCM can be pressure-held again, thereby improving the processing yield of the bonding equipment.

[0057] Reference Figure 1 and Figure 4 In this embodiment, because the relative posture between the squeezing block 8 and the LCM will be incorrect during the movement of the squeezing block 8 by the squeezing drive 81, the squeezing block 8 has the following configuration: Specifically, the squeezing block 8 includes a fixing part 82, a rotating shaft part 83, an insertion part 84, and a return spring 85. The fixing part 82 is connected to the piston rod of the squeezing drive 81; the rotating shaft part 83 is disposed through the fixing part 82 and is fixed to the fixing part 82 by means of a nut and a washer; one end of the insertion part 84 is rotatably sleeved on the rotating shaft. On part 83, the other end is used to insert into the gap of LCM; one end of the return spring 85 is connected to the fixing part 82, and the other end is connected to the insertion part 84. Two return springs 85 are symmetrically arranged with respect to the axis of the rotating shaft part 83. After the insertion part 84 is inserted into the gap of LCM, the insertion part 84 will rotate around the rotating shaft part 83 by a predetermined angle to adapt to the relative posture between LCM and the caulking block 8. This allows the caulking block 8 to more tightly insert the light-shielding adhesive into the gap of LCM, thereby helping to improve the processing yield of the bonding equipment.

[0058] The implementation principle of the light-shielding adhesive application device with secondary pressure reinforcement in this application embodiment is as follows: Before the first pressure holding process, the fixed platform plate 2 is first made horizontal by flipping the drive component 3. After the light-shielding adhesive is pasted on the LCM, the LCM is then fixed on the upper surface of the fixed platform plate 2, and the light-shielding adhesive is placed in the light-shielding adhesive positioning area 21. If the light-shielding adhesive is pasted on the front of the LCM, the first pressure holding mechanism 5 directly moves the first pressure holding block 4 down to press the light-shielding adhesive. If the light-shielding adhesive is pasted on the narrow side of the LCM, the fixed platform plate 2 is turned vertical by flipping the drive component 3, and then the first pressure holding mechanism 5 and the first pressure holding block 4 are used to complete the pressing work of the light-shielding adhesive. Thus, the light-shielding adhesive application device can adapt to two light-shielding adhesive pasting methods.
