Description

Technical Field

[0001] This utility model relates to the field of OCA bonding machine technology, specifically to an intelligent temperature-controlled OCA bonding precision temperature control device. Background Technology

[0002] OCA bonding machines, also known as "vacuum bonding machines" or "touchscreen bonding machines," are industrial automation equipment controlled by PLCs or microcontrollers. They are specifically used for bonding screens of electronic devices. Their working principle is to reduce the viscosity of OCA adhesive by heating it in a vacuum environment, thereby increasing its fluidity to fill the tiny gaps between the screen and the cover plate and reduce air bubbles. Then, the pressure of the cylinder is used to lower the mold in the vacuum cylinder, completely pressing the glass cover plate and the LCD screen together, completing the key process for repairing electronic device screens.

[0003] However, in existing intelligent temperature-controlled OCA bonding precision temperature control equipment, after completing the work of eliminating air bubbles, when the touch screen vacuum bonding machine is turned on, due to the pressure, the glass surface of the touch screen will be temporarily adsorbed onto the bonding surface of the pressure plate. When the pressure plate moves to a certain position, the touch screen that was originally bonded to the pressure plate will automatically fall off, sometimes even causing damage to the touch screen. To address this, we propose an intelligent temperature-controlled OCA bonding precision temperature control equipment. Utility Model Content

[0004] One of the technical problems this application aims to solve is: how to design an intelligent temperature-controlled OCA bonding precision temperature control device to prevent damage caused by the touch screen glass surface being temporarily adsorbed onto the bonding surface of the pressure plate after bonding.

[0006] A laminating machine housing, wherein the laminating machine housing is disposed on the laminating machine base;

[0007] Two pairs of mounting rods are provided on the laminating machine base, and a vacuum chamber is slidably connected to the laminating machine base via the two pairs of mounting rods.

[0008] A first cylinder and multiple second cylinders are mounted on the vacuum chamber. The output end of the first cylinder is connected to the outer shell of the bonding machine.

[0009] Mounting bracket, which is disposed on the base of the bonding machine;

[0010] A carrying plate is disposed on the mounting frame, and the carrying plate has a storage slot for placing workpieces.

[0011] A displacement component, disposed on the mounting bracket, is used to move the pressed touchscreen horizontally.

[0012] In some embodiments, the displacement assembly further includes a toothed plate disposed at the bottom of the carrier plate, a rotating rod rotatably connected to the mounting bracket, and a gear that engages with the toothed plate on the outer wall of the rotating rod.

[0013] In some embodiments, the laminating machine base is further provided with a pair of slide rails, and the mounting bracket is slidably connected to the laminating machine base via the pair of slide rails. A third cylinder is provided on the laminating machine base below the mounting bracket, and the output end of the third cylinder is connected to the mounting bracket.

[0014] In some embodiments, the mounting bracket has a pair of guide holes, the bottom of the carrier plate has two pairs of connecting rods, and the connecting rods have a degree of freedom to move along the length of the guide holes.

[0015] In some embodiments, one end of the rotating rod passes through one side of the mounting bracket and is provided with a handle, the outer wall of the handle is provided with anti-slip texture, and the other end of the rotating rod is rotatably connected to the other side of the mounting bracket via a bearing.

[0034] 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.

[0035] Example 1

[0036] Please see Figures 1-7 This utility model provides a technical solution: an intelligent temperature-controlled OCA bonding precision temperature control device, including a bonding machine base 1, and also including;

[0037] The laminating machine housing 2 is mounted on the laminating machine base 1;

[0038] Two pairs of mounting rods 3 are set on the laminating machine base 1, and a vacuum chamber 4 is slidably connected to the laminating machine base 1 through the two pairs of mounting rods 3.

[0039] The first cylinder 5 and multiple second cylinders 6 are all mounted on the vacuum chamber 4. The output end of the first cylinder 5 is connected to the outer shell 2 of the bonding machine. The output ends of the multiple second cylinders 6 pass through the vacuum chamber 4 and are mounted on a pressure plate 7 for pressing the workpiece.

[0040] Mounting bracket 8 is mounted on the laminating machine base 1;

[0041] The workpiece is placed on the mounting frame 8 and has a storage slot 10 for placing the workpiece.

[0042] The displacement component 100 is mounted on the mounting bracket 8 and is used to move the pressed touch screen horizontally. The bonding machine housing 2 integrates a temperature control module, a heating plate, a temperature sensor and a PID controller. The heating plate and the pressure plate 7 are thermally connected.

[0043] The displacement assembly 100 also includes a toothed plate 101 disposed at the bottom of the carrier plate 9, a rotating rod 103 rotatably connected to the mounting frame 8, and a gear 102 that cooperates with the toothed plate 101 is disposed on the outer wall of the rotating rod 103. The rotating rod 103 drives the gear 102 to rotate, and the gear 102 meshes with the toothed plate 101 to drive the carrier plate 9 to move horizontally on the mounting frame 8, thereby realizing the displacement of the workpiece after pressing.

[0044] The laminating machine base 1 is also provided with a pair of slide rails 11. The mounting frame 8 is slidably connected to the laminating machine base 1 via the pair of slide rails 11. A third cylinder 12 is provided on the laminating machine base 1 below the mounting frame 8. The output end of the third cylinder 12 is connected to the mounting frame 8. Through the connection between the output end of the third cylinder 12 and the mounting frame 8, the mounting frame 8 can be pushed to slide along the slide rails 11, thereby facilitating the removal of the workpiece plate 9 from the laminating machine housing 2, so that the user can place the workpiece in the storage slot 10, or remove the workpiece after lamination from the storage slot 10.

[0045] The mounting frame 8 has a pair of guide holes 13. The bottom of the carrying plate 9 is provided with two pairs of connecting rods 14, and the connecting rods 14 have the freedom to move along the length of the guide holes 13. One end of each pair of connecting rods 14 passes through the guide holes 13 and is provided with a nut 15 by thread. The height of the connecting rod 14 is greater than the height of the mounting frame 8, and the diameter of the connecting rod 14 is the same as the width of the guide hole 13. One end of the connecting rod 14 extends out of the guide hole 13, and the carrying plate 9 is installed on the mounting frame 8 by using the nut 15 to prevent the carrying plate 9 from falling off the mounting frame 8. The connecting rod 14 is used to guide the movement in the rectangular guide holes 13, which improves the stability of the carrying plate 9 when it moves and avoids the carrying plate 9 from shaking during the movement, thus further improving the practicality of the device.

[0046] One end of the rotating rod 103 passes through one side of the mounting bracket 8 and is provided with a handle 104. The outer wall of the handle 104 is provided with anti-slip texture. The other end of the rotating rod 103 is rotatably connected to the other side of the mounting bracket 8 through a bearing. The handle 104 makes it easy for the user to manually rotate the rotating rod 103. The anti-slip texture increases the friction between the user's hand and the handle 104, thereby preventing the user from slipping out of their hand when rotating the handle 104, and further improving the practicality of the device.

[0047] In use, firstly, by activating the third cylinder 12, the mounting bracket 8 is pushed to slide along the slide rail 11 outward from the laminating machine housing 2, and the carrier plate 9 is moved out of the laminating machine housing 2 so that the user can place the touch screen workpiece to be laminated into the storage slot 10.

[0048] Then, the third cylinder 12 is started in reverse to push the mounting bracket 8 and the carrier plate 9 back into the laminating machine housing 2. At this time, the first cylinder 5 is started to push the vacuum chamber 4 onto the carrier plate 9 so that the vacuum chamber 4 and the carrier plate 9 are attached. Then the vacuum pump in the vacuum chamber 4 is started to extract the air in the vacuum chamber 4, so that a vacuum environment is formed in the vacuum chamber 4.

[0049] Next, multiple second cylinders 6 are activated to push the pressure plate 7 to press the touch screen workpiece. At the same time, the temperature control module inside the laminating machine housing 2 starts to work, heating the pressure plate 7 through the heating plate to reduce the viscosity of the OCA adhesive and increase its fluidity, so as to fill the tiny gap between the touch screen and the cover plate.

[0050] After the pressing is completed, the vacuum pump is turned off to restore the vacuum chamber 4 to normal pressure. Then, the rotating rod 103 is rotated clockwise and counterclockwise to drive the gear 102 to rotate in both directions. The gear 102 meshes with the toothed plate 101 to drive the carrier plate 9 to move horizontally back and forth on the mounting frame 8. This allows the touch screen glass surface to be moved a certain distance away from the pressure plate 7, preventing the touch screen glass surface from being temporarily adsorbed on the pressing surface of the pressure plate after the bonding is completed. This also prevents the touch screen from moving upward when the pressure plate 7 moves upward, reducing the possibility of damage to the touch screen. Then, the first cylinder 5 is started to drive the vacuum chamber 4 to move upward, separating the pressure plate 7 from the touch screen workpiece.

[0051] Finally, the third cylinder 12 is activated again to push the mounting bracket 8 and the carrier plate 9 back to their initial positions for the next bonding operation.

[0052] Example 2

[0053] Please see Figures 8-9 This utility model provides a technical solution:

[0054] Unlike Example 1;

[0055] A third fixing piece 32 is provided on the carrier plate 9, and the third fixing piece 32 has a mounting hole 33.

[0056] A second fixing plate 31 and a first fixing plate 30 are provided on one side of the mounting bracket 8 from top to bottom. A plug rod 34 is slidably connected to the first fixing plate 30. One end of the plug rod 34 passes through the second fixing plate 31 and is inserted into the mounting hole 33.

[0057] The outer wall of the insertion rod 34 is fixed with an mounting plate 35 and a return spring 37 is sleeved thereon. The two ends of the return spring 37 abut against the mounting plate 35 and the first fixing plate 30, respectively.

[0058] In use, when the return spring 37 is in the initial position (by... Figure 9As shown), one end of the insertion rod 34 will be inserted into the mounting hole 33, thereby fixing the carrier plate 9 on the mounting frame 8 and ensuring the stability of the carrier plate 9 during use;

[0059] When it is necessary to move the platform 9 horizontally, simply pull the plug rod 34 down manually to disengage one end of the plug rod 34 from the mounting hole 33. At this time, the return spring 37 will be compressed, and then the platform 9 will move horizontally on the mounting frame 8.

[0060] After the bonding is completed, when it is necessary to fix the position of the carrier plate 9, release the insertion rod 34. Under the elastic force of the return spring 37, one end of the insertion rod 34 will quickly insert back into the mounting hole 33, fixing the carrier plate 9 back onto the mounting bracket 8, ensuring the stability of the carrier plate 9 when moving.
