Description

Technical Field

[0001] This utility model relates to the field of film application technology, and in particular to a high-efficiency bonding device for a flip-up double-sided cavity. Background Technology

[0002] The semiconductor display industry has experienced more than a decade of rapid development and technological iteration, resulting in numerous bonding technologies and equipment for various display screen forms. While existing screen bonding equipment can meet the needs of bonding, there are still some structural shortcomings. For example, Chinese patent CN222905100U discloses a medium-to-large frameless cover vacuum bonding device. In this device, the bonded product is placed on the lower vacuum adsorption plate. When bonding products again, the product on the lower vacuum adsorption plate must be removed first, and then the LCD is placed on the lower vacuum adsorption plate for the next bonding. This structure and bonding method lead to low bonding efficiency. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a high-efficiency bonding device for flipped double-sided cavities to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a high-efficiency bonding device for flipped double-sided cavities is designed, comprising:

[0006] The upper cavity has a first vacuum suction cup at the top and bottom, which is used to adsorb and fix the cover plate. The front and rear ends of the upper cavity are rotatably engaged with two mounting seats. One of the mounting seats is fixedly connected to a rotary drive device for driving the upper cavity to rotate 180°. The two mounting seats are respectively connected to a lifting drive device for driving both to lift synchronously.

[0007] The lower cavity is provided with a second vacuum suction cup inside and a vacuum suction hole on one side. The second vacuum suction cup is used to adsorb and fix the product film. The lower cavity is fixed to the base plate by a support frame. The base plate is connected to a first driving device that drives its lateral movement. A bonding driving device that drives the second vacuum suction cup to rise and fall is installed on the base plate.

[0008] When the first driving device drives the base plate to move the lower cavity to the right and align it with the upper cavity, the first vacuum suction cup and the second vacuum suction cup are aligned vertically. When the lifting driving device drives the mounting base to move the upper cavity downward, it can contact the lower cavity to form a sealed chamber. When the bonding driving device drives the second vacuum suction cup to move upward, it can cooperate with the first vacuum suction cup to bond the product film to the cover plate. The bonded product is then adsorbed and fixed on the first vacuum suction cup.

[0009] By adopting the above technical solution, first vacuum suction cups are respectively set at the top and bottom of the upper cavity. After the first vacuum suction cup at the top adsorbs the cover plate, the rotary drive device drives the upper cavity to rotate 180°, which can move the first vacuum suction cup at the top to the bottom and the first vacuum suction cup at the bottom of the upper cavity to the top. During the alignment and bonding process, another cover plate can be placed on the first vacuum suction cup at the top, which can improve the bonding efficiency. When the bonding is completed, the bonded product is adsorbed and fixed on the first vacuum suction cup. After the upper cavity rotates 180°, the cover plate adsorbed by the first vacuum suction cup at the top can be flipped to the bottom for the next bonding. When the first drive device drives the lower cavity to move to the left and reset, the product film can be directly loaded into its interior. Compared with the existing bonding device, which requires the bonded product on the lower cavity to be removed before loading, the loading time is shortened and the bonding efficiency is greatly improved.

[0010] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0011] In some embodiments, a material transfer driving device is also included. This device is connected to a positioning and loading assembly and a loading and unloading assembly arranged adjacent to each other. The material transfer driving device is used to drive the positioning and loading assembly to position the cover plate and the suction cover plate, and to position the cover plate onto the first vacuum suction cup. It is also used to drive the unloading assembly to first remove the bonded product from the first vacuum suction cup, then drive the positioning and loading assembly to position the suction cover plate onto the first vacuum suction cup, and finally drive the unloading assembly to unload the product. Existing conventional solutions first remove the bonded product for unloading, and then place the cover plate onto the vacuum suction cup. This solution, through the cooperation of the material transfer driving device with the positioning and loading assembly and the unloading assembly, first removes the bonded product from the first vacuum suction cup without unloading, and then positions the cover plate onto the first vacuum suction cup before unloading. This significantly shortens the loading time and further improves bonding efficiency.

[0012] In some embodiments, a UVW alignment platform is fixedly connected to the base plate, and a lifting device is fixedly connected to the top of the UVW alignment platform. Multiple support rods are fixedly connected to the lifting plate on the lifting device for driving the support rods to rise and fall. The upper end of each support rod passes through a perforation in the lower cavity and is fixedly connected to the mounting plate. There is a movable gap between the sidewall of the perforation and the support rod. A sealing assembly is provided between the support rod and the lower cavity to seal the lower end of the perforation. A carrier film clamping assembly, laterally slidably connected to the mounting plate, is respectively provided on the left and right sides of the second vacuum suction cup. Each of the two carrier film clamping assemblies is connected to a lateral driving device for driving its lateral movement. The UVW alignment platform is used to drive the lifting device to fine-tune the movement of the mounting plate, thereby fine-tuning the product film held by the carrier film clamping assembly. When the lifting device drives the support rods downward, the mounting plate moves the carrier film clamping assembly downward, allowing the product film clamped by the carrier film clamping assembly to be placed on the second vacuum suction cup.

[0013] In some embodiments, a first CCD camera is disposed on the left side of the upper cavity and a second CCD camera is disposed on the right side. The second CCD camera is connected to a second driving device that moves the driver laterally. The first CCD camera is used to capture the position information of the product film clamped by the carrier film clamping assembly and feed it back to the control device. The second CCD camera is used to capture the position information of the cover plate adsorbed and fixed on the first vacuum suction cup at the bottom of the upper cavity and feed it back to the control device. The control device determines the fine-tuning information based on the received position information and controls the UVW alignment platform to drive the lifting device to fine-tune and move the linkage mounting plate to drive the carrier film clamping assembly to fine-tune and move, thereby realizing the alignment between the product film and the cover plate and ensuring precise adhesion between the product film and the cover plate.

[0014] In some embodiments, a feeding drive device is also included, which is connected to a material picking component for driving the material picking component to pick up the product film and move the product film between two carrier film clamping components for clamping.

[0015] In some embodiments, the positioning and feeding assembly includes a frame, two movable frames that slide laterally with the frame, a third vacuum suction cup located between the two movable frames and fixedly connected to the frame, and a driving assembly that drives the two movable frames to move closer to each other or further away. The lower ends of the two movable frames are respectively fixedly connected to positioning blocks. When the driving assembly drives the two movable frames to move closer to each other, the positioning blocks on the left and right sides can move closer to each other and contact the two ends of the cover plate to achieve positioning of the cover plate.

[0016] In some embodiments, the drive assembly includes a power source and a lead screw that rotates with the frame. Nuts are fixedly connected to the two movable frames respectively. The threads at both ends of the lead screw are opposite to each other, and the two ends of the lead screw are threadedly engaged with the two nuts. The power source is driven to one end of the lead screw to drive the lead screw to rotate in both directions.

[0017] In some embodiments, the rotary drive device is a servo motor or a stepper motor, and the lifting drive device is a cylinder or a hydraulic cylinder.

[0018] A bonding method, based on the aforementioned high-efficiency bonding device for flipped double-sided cavities, includes the following steps:

[0019] S1. The feeding drive device drives the picking component to pick up the product film and move the product film between the two carrier film clamping components. The two carrier film clamping components clamp the two ends of the product film. The two lateral drive devices drive the two carrier film clamping components to move in opposite directions to flatten the product film. At the same time, the transfer drive device drives the positioning feeding component to move to the picking position. The positioning feeding component positions the cover plate and adsorbs the cover plate. Then the transfer drive device drives the positioning feeding component to move above the first vacuum suction cup. The positioning feeding component positions the cover plate on the first vacuum suction cup at the top. The first vacuum suction cup adsorbs and fixes the cover plate.

[0020] S2. The feeding drive device drives the picking component to pick up the product film again and move the picked-up product film to the loading position. The transfer drive device drives the positioning feeding component to pick up the cover plate again and move the picked-up cover plate to the loading position.

[0021] At the same time, the rotary drive device drives the upper cavity to rotate 180°, causing the cover plate adsorbed by the first vacuum suction cup at the top of the upper cavity to flip to the bottom of the upper cavity.

[0022] S3. The first driving device drives the base plate to move to the right, causing the lower cavity to move to the right and below the first CCD camera. The first CCD camera captures the product film position information and feeds it back to the control device. The second driving device drives the second CCD camera to move to the left and below the upper cavity. The second CCD camera captures the position information of the cover plate on the first vacuum suction cup at the bottom of the upper cavity and feeds it back to the control device. The control device determines the fine-tuning information based on the received position information and controls the UVW alignment platform to drive the lifting device to fine-tune the movement of the linkage mounting plate, thereby fine-tuning the position of the product film held by the carrier film clamping assembly. After the fine-tuning is completed, the lifting device drives the support rod to move down, and the linkage mounting plate moves the carrier film clamping assembly down, so that the product film is placed on the second vacuum suction cup. The second vacuum suction cup adsorbs and fixes the product film. The second driving device drives the second CCD camera to move to the right and reset.

[0023] At the same time, the material transfer drive device drives the positioning and feeding assembly to position the picked-up cover plate on the first vacuum suction cup at the top of the upper cavity, and the first vacuum suction cup adsorbs and fixes the cover plate.

[0024] S4. The first driving device drives the base plate to move the lower cavity to the right and below the upper cavity to correspond with the upper cavity. The lifting driving device drives the mounting base to move the upper cavity down and contact the lower cavity to form a sealed chamber. The vacuum pump connects the suction pipe to the vacuum suction hole on one side of the lower cavity to evacuate the sealed chamber.

[0025] At the same time, the material transfer drive device drives the positioning and feeding component again to pick up the cover plate and move the picked-up cover plate to the feeding position;

[0026] S5. The bonding drive device drives the second vacuum suction cup to move upward and cooperate with the first vacuum suction cup to bond the product film and the cover plate. After bonding, the second vacuum suction cup releases its adsorption on the product film. The bonding drive device drives the second vacuum suction cup to move downward and reset. The first drive device drives the base plate to move the lower cavity to the left and reset. The bonded product is adsorbed and fixed on the first vacuum suction cup. The rotation drive device drives the upper cavity to rotate 180°, so that the cover plate adsorbed by the first vacuum suction cup at the top of the upper cavity flips to the bottom of the upper cavity. At the same time, the product adsorbed by the first vacuum suction cup at the bottom of the upper cavity flips to the top of the upper cavity.

[0027] S6. The material transfer drive device drives the unloading component to remove the bonded product first, and then drives the positioning and loading component to position the removed cover plate on the first vacuum suction cup at the top. The first vacuum suction cup adsorbs and fixes the cover plate. Then the unloading component is driven to move the removed product to the unloading position for unloading. After unloading is completed, the material transfer drive device drives the positioning and loading component to remove the cover plate again and move the removed cover plate to the loading position.

[0028] The technical effect of this method is as follows: When the material transfer drive device drives the positioning and loading component to place the picked-up cover plate onto the first vacuum suction cup at the top of the upper cavity, the material transfer drive device drives the positioning and loading component again to pick up the cover plate and move it to the loading position. When the rotary drive device drives the upper cavity to rotate 180°, the cover plate adsorbed by the first vacuum suction cup at the top of the upper cavity flips to the bottom of the upper cavity. After the first vacuum suction cup at the bottom of the upper cavity moves to the top, the material transfer drive device drives the positioning and loading component again to move from the loading position to above the first vacuum suction cup and place the cover plate on the first vacuum suction cup. Then, the material transfer drive device drives the positioning and loading component again to pick up the cover plate and move it to the loading position. Thus, during the bonding process of the first product film and the first cover plate, the material transfer drive device drives the positioning and loading component to pick up the cover plate and move it to the loading position and place it on the empty first vacuum suction cup at the top of the upper cavity multiple times, preparing for the bonding of the next product. This can greatly and effectively improve the bonding efficiency of the product. In addition, by using the material transfer drive device in conjunction with the positioning and feeding components and the unloading components, the bonded product is first removed from the first vacuum suction cup without unloading. Instead, the cover plate is positioned on the first vacuum suction cup before unloading, which can greatly shorten the feeding time and further improve the bonding efficiency.

The left and right movement of the base plate 23 is linked to the left and right movement of the lower cavity 2.

[0045] A bonding drive device 8 for driving the second vacuum suction cup 21 to rise and fall is installed on the base plate 23.

The vacuum pump is used to create a vacuum. When the material transfer drive device 3 drives the positioning and loading assembly 31 to the material picking position, the drive assembly 314 drives the two movable frames 312 to move closer to each other, which in turn moves the left and right positioning blocks 3121 closer to each other.

When the bonding driving device 8 drives the second vacuum suction cup 21 to move upward, it can cooperate with the first vacuum suction cup 11 to bond the product film to the cover plate. After bonding, the bonded product is adsorbed and fixed on the first vacuum suction cup 11.

The two ends of the screw are rotatably engaged with the screw seat fixed on the base plate 101. The nut is fixed to the drive plate 104. The forward and reverse rotation of the motor drive screw can drive the nut to move left and right, thereby driving the drive plate 104 to move left and right. The left and right movement of the drive plate 104 drives the cylindrical part 1031 to rise or fall, and links the lifting plate 103 to rise or fall.

[0053] The lifting plate 103 of the lifting device 10 is fixedly connected to two, three, four or more support rods 107. The upper end of the support rod 107 passes through a perforation on the lower cavity 2 and is fixedly connected to the mounting plate 108 inside the lower cavity 2. There is a movable gap between the side wall of the perforation and the support rod 107, which is used to allow the support rod 107 to move left and right and back and forth.

The two transverse drive devices 1002 drive the two carrier film clamping components 1001 to move in opposite directions to flatten the product film. At the same time, the transfer drive device 3 drives the positioning feeding component 31 to move to the picking position.

[0063] At the same time, the rotary drive device 51 drives the upper cavity 1 to rotate 180°, causing the cover plate adsorbed by the first vacuum suction cup 11 at the top of the upper cavity 1 to flip to the bottom of the upper cavity 1.

[0064] S3. The first driving device 7 drives the base plate 23 to move to the right, causing the lower cavity 2 to move to the right below the first CCD camera D1.

The second CCD camera D2 captures the cover plate position information on the first vacuum suction cup 11 at the bottom of the upper cavity 1 and feeds it back to the control device. The control device determines the fine-tuning information based on the received position information and controls the UVW alignment platform 9 to drive the lifting device 10 to fine-tune the movement of the linkage mounting plate 108, thereby driving the carrier film clamping assembly 1001 to fine-tune the movement of the carrier film clamping assembly 1001. After the fine-tuning is completed, the lifting device 10 drives the support rod 107 to move down, and the linkage mounting plate 108 drives the carrier film clamping assembly 1001 to move down, so that the product film is placed on the second vacuum suction cup 21. The second vacuum suction cup 21 adsorbs and fixes the product film. The second driving device 1003 drives the second CCD camera D2 to move to the right and reset.

[0066] S4. The first driving device 7 drives the base plate 23 to move the lower cavity 2 to the right and below the upper cavity 1, corresponding vertically to the upper cavity 1. The lifting driving device 52 drives the mounting base 5 to move the upper cavity 1 down and contact the lower cavity 2 to form a sealed chamber. The vacuum pump is connected to the vacuum suction hole on the rear side of the lower cavity 2 to evacuate the sealed chamber.

[0067] At the same time, the material transfer drive device 3 drives the positioning and feeding assembly 31 again to pick up the cover plate and move the picked-up cover plate to the feeding position;

[0068] S5. After the vacuum level in the sealed chamber reaches the set standard, the bonding drive device 8 drives the second vacuum suction cup 21 to move upward and cooperate with the first vacuum suction cup 11 to bond the product film and the cover plate. After bonding, the second vacuum suction cup 21 releases its adsorption on the product film. The bonding drive device 8 drives the second vacuum suction cup 21 to move downward and reset. The first drive device 7 drives the base plate 23 to move the lower cavity 2 to the left and reset. The bonded product is adsorbed and fixed on the first vacuum suction cup 11. The rotation drive device 51 drives the upper cavity 1 to rotate 180°, so that the cover plate adsorbed by the first vacuum suction cup 11 at the top of the upper cavity 1 flips to the bottom of the upper cavity 1. At the same time, the product adsorbed by the first vacuum suction cup 11 at the bottom of the upper cavity 1 flips to the top of the upper cavity 1.

[0069] S6. The material transfer drive device 3 drives the unloading assembly 32 to remove the bonded product first. Then, it drives the positioning and loading assembly 31 to position the removed cover plate on the first vacuum suction cup 11 at the top. The first vacuum suction cup 11 adsorbs and fixes the cover plate. Then, it drives the unloading assembly 32 to move the removed product to the unloading position for unloading. After unloading, the material transfer drive device 3 drives the positioning and loading assembly 31 to remove the cover plate again and move the removed cover plate to the loading position. The loading drive device 4 drives the picking assembly 41 to move the picked product film between the two carrier film clamping assemblies 1001. The above steps are repeated to achieve continuous bonding production of continuous product film and cover plate.
