Description

Technical Field

[0001] This invention relates to the field of LCD manufacturing technology, specifically to an antistatic fully automatic bonding equipment. Background Technology

[0002] Black and white segment LCD screens (also known as segment LCDs or segment-type LCDs) are a very common and basic type of LCD display. They are mainly used to display fixed, simple patterns, characters, numbers, or symbols, rather than displaying arbitrary images like dot matrix screens. Traditional large-size segment LCD instrument panels in vehicles either have the LCD directly exposed or have a glass cover plate attached to the LCD surface. This cannot meet customers' requirements for a seamless black appearance and high-definition information display of the instrument panel, and the anti-static performance is generally poor. Therefore, the market demand for segment LCD instrument panels with high anti-static performance is gradually increasing.

[0003] High-antistatic segment LCD instruments typically utilize optical adhesive to fully bond a glass cover plate coated with an electrostatic shielding layer to the LCD screen, giving the instrument a seamless black appearance while improving the clarity and antistatic performance of the LCD screen. Before bonding the glass cover plate to the LCD screen, the relevant components need to be cleaned. Although current bonding production lines can perform pre-dust cleaning, it is difficult to effectively treat the bonding station with antistatic agents. As a result, if static electricity is generated during component transfer and bonding, dust particles will be attracted, affecting the bonding tightness. Therefore, an antistatic fully automatic bonding device is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that current bonding production lines have difficulty in effectively treating the bonding station with antistatic agents, which leads to the generation of static electricity during component transfer and bonding, resulting in the attraction of dust particles and affecting the bonding tightness. This invention provides an antistatic fully automatic bonding device.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] An antistatic fully automatic bonding device includes two grounded support frames. Each grounded support frame has a drive-installed conveyor belt inside. The top of each conveyor belt has multiple evenly distributed conveyor slots for placing and conveying LCD screens and glass cover plates, respectively. One end of each grounded support frame is provided with an insulated tunnel.

[0007] Furthermore, a conductive metal patch is fixedly installed on the top of the conveying groove, and a plurality of evenly distributed conductive through holes are opened at the bottom of the conveying groove. A plurality of evenly distributed conductive strips are fixedly installed on the bottom of the conductive metal patch, and the plurality of conductive strips are respectively fixedly installed inside the plurality of conductive through holes and in contact with the upper surface of the support plate.

[0008] A transfer robotic arm mechanism is provided between the two grounding support frames. The transfer robotic arm mechanism is equipped with a vacuum suction cup. The transfer robotic arm mechanism is used to drive the vacuum suction cup to transfer the glass cover plate to be attached to the LCD screen. The transfer robotic arm mechanism includes a rotary table disposed between the two grounding support frames. A lifting arm is fixedly installed on the top of the driving end of the rotary table. A horizontal telescopic boom is fixedly installed on the telescopic end of the lifting arm. A hanger is fixedly installed on the telescopic end of the horizontal telescopic boom. The vacuum suction cup is fixedly installed at the bottom of the hanger. An adsorption lip is fixedly installed on the bottom of the vacuum suction cup. Multiple evenly distributed negative pressure suction tubes are fixedly installed on the top of the vacuum suction cup. The bottom ends of the negative pressure suction tubes all extend into the interior of the adsorption lip. The top ends of the multiple negative pressure suction tubes are fixedly installed with the same multi-port suction tube. A vacuum pump is fixedly installed on one side of the lifting arm. One end of the multi-port suction tube is connected to the air inlet of the vacuum pump.

[0009] Furthermore, a plurality of evenly distributed support rollers are rotatably mounted inside the grounding support frame, and the plurality of support rollers are all located inside the conveyor belt. A support plate is fixedly mounted inside the grounding support frame, and the support plate is located inside the conveyor belt and corresponds to the position of the vacuum suction cup. The upper surface of the support plate is in contact with the lower surface of the conveyor belt.

[0010] Furthermore, a filter box is fixedly installed on one side of the lifting arm, one end of the multi-channel suction pipe is fixedly installed on the air inlet end of the filter box, and the air outlet end of the filter box is connected to the air inlet end of the vacuum pump.

[0011] Furthermore, an industrial vacuum cleaner is provided on one side of one of the grounding support frames, and a U-shaped air guide plate is fixedly installed on one side of the industrial vacuum cleaner. The U-shaped air guide plate corresponds to the position of the vacuum port of the industrial vacuum cleaner and faces the upper surface of the conveyor belt on the same side.

[0012] Furthermore, a plurality of vertically arranged spring telescopic rods are fixedly installed at the bottom of the U-shaped air guide plate. The telescopic ends of the spring telescopic rods extend into the interior of the U-shaped air guide plate and are fixedly installed with the same L-shaped air guide plate. The L-shaped air guide plate is slidably installed on one side of the industrial vacuum cleaner. A pressing frame is fixedly installed on the top of the L-shaped air guide plate, and an upper pressing rod corresponding to the position of the pressing frame is fixedly installed at the bottom of the hanger.

[0013] Furthermore, the negative pressure straw is provided with a pressing mechanism inside for lightly pressing the glass cover to achieve adhesion. The pressing mechanism includes a suspension ring fixedly installed inside the bottom end of the negative pressure straw. The suspension ring has multiple evenly distributed ventilation holes. A push rod housing is fixedly inserted inside the suspension ring. A vertically arranged electric push rod is fixedly installed inside the push rod housing. The telescopic end of the electric push rod extends downward to the outside of the push rod housing and the negative pressure straw and is fixedly installed with a sealing rubber disc. The sealing rubber disc is located at the bottom of the suspension ring.

[0014] Furthermore, the sealing disc has a water outlet groove inside, a conductive metal disc is fixedly installed at the bottom of the sealing disc, a circulation pump is fixedly installed on one side of the hanger, a water storage container connected to the water inlet of the circulation pump is fixedly installed on the top of the circulation pump, a water supply network and a return network are fixedly installed around the periphery of the multiple negative pressure suction pipes, one end of the water supply network is connected to the water outlet of the circulation pump, and one end of the return network extends into the interior of the circulation pump and is connected to the water storage container. A water inlet pipe and a water outlet pipe are fixedly installed on the side wall of each negative pressure suction pipe, and the water inlet pipe and the water outlet pipe are respectively connected to the water supply network and the return network. Two water supply hoses connected to the water outlet groove are fixedly installed on the top of the sealing disc, and the top ends of the two water supply hoses pass through two vent holes and are respectively connected to the water inlet pipe and the water outlet pipe.

[0015] Furthermore, a grounding cable is fixedly installed on the top of the water storage container, one end of which is fixedly plugged into one side of the hanger, and the other end of which extends into the interior of the water storage container.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention uses conductive metal discs to fit the glass cover plate. A circulating pump draws conductive liquid from the water storage container and transfers it to each outlet tank. The liquid is then transferred back to the water storage container via a water delivery hose, outlet pipe, and return pipe network, thus completing the circulation of the conductive liquid. The static electricity accumulated on the glass cover plate is conducted to the water storage container through the flow of the conductive liquid, achieving static electricity conduction on the glass cover plate and reducing dust adhesion on the glass cover plate.

[0018] 2. By setting conductive metal patches, the upper surfaces of the glass cover and the LCD screen are in contact with the conductive metal patches. When the conveyor belt stops, the conductive metal patches are grounded, so that the static electricity accumulated on the glass cover and the LCD screen during the transmission process is conducted through the conductive metal patches, conductive strips, support plates and grounding support frames, thereby improving the antistatic effect of the bonding equipment.

[0019] 3. By setting an L-shaped air guide plate, the vacuum suction cup and adsorption lip carry the glass cover down, and the pressing frame slides down, so that the area of ​​the industrial vacuum cleaner's suction port gradually decreases. As a result, the airflow intensity gradually increases as the glass cover and LCD screen get closer, changing from absorbing floating dust in the surrounding air to directly and forcefully adsorbing dust on the two surfaces, thus ensuring the cleanliness of the two surfaces.

[0020] 4. By setting a sealing pad, the present invention allows the electric push rod to move the sealing pad downward when the adsorption lip is bonded to the glass. The interior of the vacuum suction cup is connected to the negative pressure suction tube through the vent hole, so that the electric push rod acts as a control valve. After the glass cover is bonded to the LCD screen, the sealing pad continues to press down and bond to the top of the glass cover, so that the glass cover and the LCD screen are bonded more tightly under light pressure.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] In the description of the embodiments of the present invention, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0035] like Figures 1 to 9As shown, an antistatic fully automatic bonding device includes two grounded support frames 1, as... Figure 1 As shown, the grounding support frame 1 has a drive conveyor belt 2 installed inside, and one end of the grounding support frame 1 is provided with an insulated tunnel 3.

[0036] In this embodiment, the grounding support frame 1 is driven to the conveyor belt 2 by the motor unit and the transmission rollers at both ends. The conveyor belt 2 is tensioned on the transmission rollers. By controlling the rotation of the transmission rollers, the conveyor belt 2 is driven to carry out transmission.

[0037] like Figure 1 , Figure 8 , Figure 9 As shown, the top of the conveyor belt 2 is provided with multiple evenly distributed conveyor slots 201. The conveyor slots 201 are used to place and transport LCD screens and glass covers respectively. Specifically, a conductive metal patch 34 is fixedly installed on the top of the conveyor slot 201, and multiple evenly distributed conductive through holes 202 are provided on the bottom of the conveyor slot 201. Multiple evenly distributed conductive strips 35 are fixedly installed on the bottom of the conductive metal patch 34. The multiple conductive strips 35 are respectively fixedly installed inside the multiple conductive through holes 202 and in contact with the upper surface of the support plate 33.

[0038] In this embodiment, the inside of the transfer groove 201 is provided with a patch groove for embedding and fixing the conductive metal patch 34, so that the conductive metal patch 34 is embedded and fixed inside the transfer groove 201, and the upper surface of the conductive metal patch 34 is kept on the same plane as the horizontal inner wall of the transfer groove 201.

[0039] More specifically, by setting conductive metal patches 34, the upper surfaces of both the glass cover and the LCD screen are in contact with the conductive metal patches 34. When the conveyor belt 2 stops transmitting, the multiple conductive strips 35 at the bottom of the conductive metal patches 34 will contact the support plate 33, thereby cooperating with the grounding support frame 1 to complete grounding. This allows the static electricity accumulated on the glass cover and the LCD screen during transmission to be conducted through the conductive metal patches 34, conductive strips 35, support plate 33, and grounding support frame 1, thereby improving the antistatic effect of the bonding equipment.

[0040] A transfer robotic arm mechanism is installed between the two grounding support frames 1. A vacuum suction cup 8 is mounted on the transfer robotic arm mechanism. The transfer robotic arm mechanism is used to drive the vacuum suction cup 8 to transfer the glass cover plate to be attached to the LCD screen. Figure 1 , Figure 2 As shown, specifically, the transfer robotic arm mechanism includes a rotary table 4 disposed between two grounded support frames 1. A lifting arm 5 is fixedly installed on the top of the drive end of the rotary table 4. A horizontal telescopic boom 6 is fixedly installed on the telescopic end of the lifting arm 5. A hanger 7 is fixedly installed on the telescopic end of the horizontal telescopic boom 6. Figure 3As shown, the vacuum suction cup 8 is fixedly installed at the bottom of the hanger 7. An adsorption lip 9 is fixedly installed at the bottom of the vacuum suction cup 8. Multiple evenly distributed negative pressure suction tubes 10 are fixedly installed at the top of the vacuum suction cup 8. The bottom ends of the negative pressure suction tubes 10 all extend into the interior of the adsorption lip 9. The top ends of the multiple negative pressure suction tubes 10 are fixedly installed with the same multi-pass suction tube 11. A vacuum pump 12 is fixedly installed on one side of the lifting arm 5. One end of the multi-pass suction tube 11 is connected to the air inlet of the vacuum pump 12.

[0041] In this embodiment, the rotary table 4 is driven by a servo motor and consists of a fixed base and a drive end. The fixed base is fixed to the ground or platform, and the drive disk is rotated inside the fixed base. The drive disk rotates inside the fixed base through the servo motor and gear mechanism. Secondly, multiple sets of transfer robotic arm mechanisms can be set between the two conveyor belts 2, and supporting components can be added to achieve multi-station bonding and improve bonding efficiency. Depending on the different structures of the LCD segment screen, another set of mechanical grippers and material conveying structures can be added to one side of the lifting arm 5 to place ribbon cables between the glass cover and the LCD screen, so that when the finished product is in use, the static electricity between the glass cover and the LCD screen can be grounded through the ribbon cables.

[0042] More specifically, in use, the cleaned glass cover and the LCD screen with optical adhesive coated on its upper surface are placed in multiple conveyor slots 201 on two conveyor belts 2 for transport. When they are transferred from the insulated tunnel 3 to one side of the transfer robotic arm mechanism, the conveyor rollers stop, the horizontal telescopic boom 6 drives the vacuum suction cup 8 to move directly above the glass cover, and the lifting arm 5 drives the vacuum suction cup 8 and the adsorption lip 9 to press down and adhere to the top of the glass cover. At this time, the vacuum pump 12 draws air from the inside of each negative pressure suction tube 10 through the multi-channel suction tube 11, thereby rapidly lowering the pressure. The air pressure inside the low-vacuum suction cup 8 and the adsorption lip 9 causes the glass cover to be adsorbed onto the bottom of the adsorption lip 9 under negative pressure. Then, the vacuum suction cup 8 and the adsorption lip 9 move the glass cover upward, and the rotary table 4 drives the transfer robotic arm mechanism to rotate as a whole, so that the glass cover moves to the top of the LCD screen. As the lifting arm 5 retracts, the glass cover is adhered to the LCD screen. Then, the suction stops and air is re-injected into the vacuum suction cup 8 and the adsorption lip 9, so that the glass cover detaches from the adsorption lip 9. After that, the transfer robotic arm mechanism resets, and the transfer roller operates again to perform the next round of bonding, thereby realizing automated bonding.

[0043] like Figure 8As shown, multiple evenly distributed support rollers 32 are rotatably installed inside the grounding support frame 1. Specifically, the multiple support rollers 32 are all located inside the conveyor belt 2. A support plate 33 is fixedly installed inside the grounding support frame 1. The support plate 33 is located inside the conveyor belt 2 and corresponds to the position of the vacuum suction cup 8. The upper surface of the support plate 33 is in contact with the lower surface of the conveyor belt 2.

[0044] More specifically, by setting support rollers 32 and support plates 33, multiple support rollers 32 can be supported inside the conveyor belt 2 to prevent the middle section of the conveyor belt 2 from falling and affecting the transmission of the glass cover and the LCD screen. The support plates 33 are also supported inside the conveyor belt 2. When the vacuum suction cup 8 carries the glass cover down, the support plates 33 can play the role of plate support, making the force on the glass cover and the LCD screen more even.

[0045] like Figure 2 As shown, a filter box 36 is fixedly installed on one side of the lifting arm 5. Specifically, one end of the multi-pass suction pipe 11 is fixedly installed on the air inlet end of the filter box 36, and the air outlet end of the filter box 36 is connected to the air inlet end of the vacuum pump 12.

[0046] In this embodiment, both the vacuum pump 12 and the filter box 36 are mounted on the fixed end of the lifting arm 5.

[0047] More specifically, by setting up a filter box 36, the air inside the vacuum suction cup 8 and the adsorption lip 9 is drawn into the filter box 36 through the multi-pass suction tube 11. The dust mixed in the air will be adsorbed and filtered by the adsorption particles inside the filter box 36, thereby reducing the burden on the vacuum pump 12 and simultaneously adsorbing the dust on the upper surface of the glass cover.

[0048] like Figure 1 , Figure 7 As shown, an industrial vacuum cleaner 26 is installed on one side of one of the grounding support frames 1. Specifically, a U-shaped air guide plate 27 is fixedly installed on one side of the industrial vacuum cleaner 26. The U-shaped air guide plate 27 corresponds to the position of the suction port of the industrial vacuum cleaner 26 and faces the upper surface of the conveyor belt 2 on the same side.

[0049] In this embodiment, the industrial vacuum cleaner 26 is disposed on one side of the conveyor belt 2 used to transport the LCD screen, with its suction port facing the LCD screen.

[0050] More specifically, by setting up an industrial vacuum cleaner 26, when the LCD screen is transported to the side of the transfer robotic arm mechanism, the floating dust around the LCD screen will be sucked into the suction port by the industrial vacuum cleaner 26, preventing the floating dust in the air from falling on the screen or optical adhesive surface, which could cause problems such as bubbles or loose bonding.

[0051] like Figure 7 , Figure 3 As shown, specifically, multiple vertically arranged spring telescopic rods 28 are fixedly installed at the bottom of the U-shaped air guide plate 27. The telescopic ends of the spring telescopic rods 28 extend into the interior of the U-shaped air guide plate 27 and are fixedly installed with the same L-shaped air guide plate 29. The L-shaped air guide plate 29 is slidably installed on one side of the industrial vacuum cleaner 26. A pressing frame 30 is fixedly installed on the top of the L-shaped air guide plate 29. An upper pressure rod 31 corresponding to the position of the pressing frame 30 is fixedly installed at the bottom of the hanger 7.

[0052] More specifically, by setting up the L-shaped air guide plate 29, as the vacuum suction cup 8 and the adsorption lip 9 carry the glass cover down, the upper pressure rod 31 above the vacuum suction cup 8 will press down on the pressing frame 30, causing the pressing frame 30 to slide down along the U-shaped air guide plate 27. This gradually reduces the space between the L-shaped air guide plate 29 and the U-shaped air guide plate 27, and gradually reduces the area of ​​the suction port of the industrial vacuum cleaner 26. As a result, the airflow intensity gradually increases as the glass cover and the LCD screen get closer, changing from absorbing floating dust in the surrounding air to directly and forcefully adsorbing dust on the contact surface of the two, thus ensuring the cleanliness of the contact surface.

[0053] The negative pressure straw 10 is internally equipped with a pressing mechanism for lightly pressing the glass cover to achieve a seal, such as... Figure 4 , Figure 5 , Figure 6 As shown, specifically, the pressure mechanism includes a suspension ring 13 fixedly installed inside the bottom end of the negative pressure suction tube 10. The suspension ring 13 has multiple evenly distributed ventilation holes 1301. A push rod housing 14 is fixedly inserted inside the suspension ring 13. A vertically arranged electric push rod 15 is fixedly installed inside the push rod housing 14. The telescopic end of the electric push rod 15 extends downward to the outside of the push rod housing 14 and the negative pressure suction tube 10 and is fixedly installed with a sealing rubber plate 16. The sealing rubber plate 16 is located at the bottom of the suspension ring 13.

[0054] In this embodiment, one side of the push rod housing 14 extends to the outside of the negative pressure suction tube 10, and the joint between the push rod housing 14 and the negative pressure suction tube 10 is sealed.

[0055] More specifically, by setting up a pressure-sensitive mechanism, when the adhesive lip 9 is bonded to the glass, the electric push rod 15 inside the push rod housing 14 will drive the sealing adhesive disc 16 to move down and contact the upper surface of the glass cover. After the sealing adhesive disc 16 is separated from the lower surface of the suspension ring 13, the interior of the vacuum suction cup 8 is connected to the negative pressure suction tube 10 through the vent hole 1301, so that the electric push rod 15 acts as a control valve. After the glass cover is bonded to the LCD screen, the sealing adhesive disc 16 continues to press down and bond to the top of the glass cover, so that the glass cover and the LCD screen are lightly pressed and bonded more tightly.

[0056] like Figure 4 , Figure 6 As shown, specifically, a water outlet groove 1601 is provided inside the sealing disc 16, a conductive metal disc 17 is fixedly installed at the bottom of the sealing disc 16, and a circulation pump 18 is fixedly installed on one side of the hanger 7. Figure 3 , Figure 5 As shown, a water storage container 19 connected to the water inlet of the circulating pump 18 is fixedly installed on the top of the circulating pump 18. A water supply network 20 and a return network 21 are fixedly installed around the periphery of multiple negative pressure suction pipes 10. One end of the water supply network 20 is connected to the water outlet of the circulating pump 18, and one end of the return network 21 extends into the interior of the circulating pump 18 and is connected to the water storage container 19. A water inlet pipe 23 and a water outlet pipe 24 are fixedly installed on the side wall of each negative pressure suction pipe 10. The water inlet pipe 23 and the water outlet pipe 24 are connected to the water supply network 20 and the return network 21, respectively. Two water supply hoses 22 connected to the water outlet 1601 are fixedly installed on the top of the sealing disc 16. The top ends of the two water supply hoses 22 pass through two vent holes 1301 and are connected to the water inlet pipe 23 and the water outlet pipe 24, respectively.

[0057] In this embodiment, the conductive metal disc 17 is embedded and fixed in the embedding hole opened at the bottom of the sealing disc 16, and the upper surface of the conductive metal disc 17 is located inside the water outlet tank 1601.

[0058] More specifically, by setting the conductive metal disc 17, after the sealing disc 16 is attached to the glass cover, the conductive metal disc 17 is also attached to the glass cover. At this time, the circulating pump 18 draws the conductive liquid inside the water storage container 19 and transmits it through the water supply network 20, the inlet pipe 23, and the water supply hose 22 to each outlet tank 1601 to contact the upper surface of the conductive metal disc 17. Then, it is transmitted back to the water storage container 19 through the water supply hose 22, the outlet pipe 24, and the return water network 21, completing the circulation of the conductive liquid. The static electricity accumulated on the glass cover is conducted to the water storage container 19 through the flow of the conductive liquid, realizing the static electricity conduction of the glass cover and reducing the dust adhesion on the glass cover.

[0059] like Figure 3 As shown, specifically, a grounding cable 25 is fixedly installed on the top of the water storage container 19. One end of the grounding cable 25 is fixedly plugged into one side of the hanger 7, and the other end of the grounding cable 25 extends into the interior of the water storage container 19.

[0060] In this embodiment, the hanger 7 is equipped with a grounding socket for connecting the grounding cable 25.

[0061] More specifically, by setting up a grounding cable 25, the static electricity accumulated inside the water storage container 19 will also be conducted to the hanger 7 by the grounding cable 25, and then further conducted through the grounding socket, effectively preventing the accumulation of static electricity inside the water storage container 19.

[0062] In summary: Before bonding: The cleaned glass cover and the LCD screen with optical adhesive coated on the upper surface are placed in multiple conveyor slots 201 on two conveyor belts 2 for transportation. When the two are transferred from the heat-insulated tunnel 3 to one side of the transfer robotic arm mechanism, the transfer roller stops, and multiple conductive strips 35 at the bottom of the conductive metal patch 34 will contact the support plate 33, thereby cooperating with the grounding support frame 1 to complete the grounding. During the transportation process, the static electricity accumulated on the glass cover and the LCD screen will be conducted through the conductive metal patch 34, conductive strips 35, support plate 33 and grounding support frame 1. The floating dust around the LCD screen will be sucked into the suction port by the industrial vacuum cleaner 26.

[0063] During bonding: The horizontal telescopic boom 6 drives the vacuum suction cup 8 to move directly above the glass cover plate. The lifting arm 5 drives the vacuum suction cup 8 and the adsorption lip 9 to press down and bond to the top of the glass cover plate. The electric push rod 15 inside the push rod housing 14 drives the sealing lip 16 to move down and contact the upper surface of the glass cover plate. The circulation pump 18 circulates the conductive liquid, conducting the static electricity accumulated on the glass cover plate to the water storage container 19 through the flow of the conductive liquid. After the sealing lip 16 detaches from the lower surface of the suspension ring 13, the interior of the vacuum suction cup 8 is connected to the negative pressure suction tube 10 through the vent hole 1301. At this time, the vacuum pump 12 draws air from the interior of each negative pressure suction tube 10 through the multi-pass suction tube 11, thereby rapidly reducing the air pressure inside the vacuum suction cup 8 and the adsorption lip 9, so that the glass cover plate is adsorbed to the bottom of the adsorption lip 9 under the action of negative pressure. Then the vacuum suction cup 8 and the adsorption lip 9 drive... As the glass cover moves upward, the rotary table 4 drives the transfer robotic arm mechanism to rotate as a whole, moving the glass cover directly above the LCD screen. As the lifting arm 5 retracts, the glass cover is adhered to the LCD screen. As the vacuum suction cup 8 and the suction lip 9 carry the glass cover downward, the upper pressure rod 31 above the vacuum suction cup 8 presses down on the pressing frame 30, causing the pressing frame 30 to slide downward along the U-shaped air guide plate 27. This gradually reduces the space between the L-shaped air guide plate 29 and the U-shaped air guide plate 27, and gradually reduces the area of ​​the suction port of the industrial vacuum cleaner 26. As a result, the airflow intensity gradually increases as the glass cover and the LCD screen get closer, changing from absorbing floating dust in the surrounding air to directly and forcefully adsorbing dust on the two surfaces. The sealing pad 16 continues to press down and adhere to the top of the glass cover, making the glass cover and the LCD screen adhere more tightly under light pressure.

[0064] After bonding: Vacuum pump 12 stops sucking air and re-supplys air to vacuum suction cup 8 and adsorption lip 9, causing the glass cover to detach from adsorption lip 9. Then the transfer robotic arm mechanism resets, and the transfer roller operates again to perform the next round of bonding, thereby achieving automated bonding.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
