Description

Technical Field

[0001] The present invention relates to the technical field of LCD production, and in particular to an antistatic fully automatic laminating device. Background Art

[0002] LCD black and white segment code liquid crystal display (also known as segment code LCD or pen segment LCD) is a very common and basic type of liquid crystal display. It is mainly used to display fixed, simple patterns, characters, numbers or symbols, rather than arbitrary images like dot matrix screens. Traditional large-size segment code LCD instruments on vehicles either have the LCD directly exposed or a glass cover framed on the LCD surface. These cannot meet customers' requirements for the integrated black appearance of the instrument display and high-definition information display, and their anti-static performance is average. Therefore, the market demand for segment code LCD instruments with high anti-static performance is gradually increasing.

[0003] Segment LCD instruments with high antistatic performance generally use optical adhesive to fully bond a glass cover plate coated with an electrostatic shielding layer to the LCD screen, giving the instrument a one-piece black appearance while improving the clarity and antistatic performance of the LCD screen. Before bonding the glass cover plate and the LCD screen, the relevant components need to be cleaned. Although current bonding production lines can perform pre-cleaning, it is difficult to effectively perform antistatic treatment on the bonding station. As a result, if the components generate static electricity during transmission and bonding, they will absorb dust particles, which in turn affects the tightness of the bonding. For this reason, an antistatic fully automatic bonding equipment is proposed. Summary of the Invention

Therefore, they cannot be understood as limitations on the present invention.

[0021] like Figures 1 to 9As shown, an antistatic fully automatic laminating device includes two grounded support frames 1, as shown in FIG. Figure 1 As shown, a conveyor belt 2 is driven and installed inside the ground support frame 1, and an insulation tunnel 3 is provided at one end of the ground support frame 1.

[0022] In this embodiment, the ground support frame 1 is connected to the transmission rollers at both ends and the conveyor belt 2 through a motor group. The conveyor belt 2 is tensioned on the transmission rollers, and the conveyor belt 2 is driven to transmit by controlling the rotation of the transmission rollers.

[0023] like Figure 1 、 Figure 8 、 Figure 9 As shown, a plurality of evenly distributed conveying grooves 201 are provided on the top of the conveyor belt 2, and the conveying grooves 201 are used to place and transport LCD screens and glass cover plates respectively. Specifically, a conductive metal patch 34 is fixedly installed on the top of the conveying groove 201, and a plurality of evenly distributed conductive through holes 202 are provided on the bottom of the conveying groove 201. A plurality of evenly distributed conductive strips 35 are fixedly installed on the bottom of the conductive metal patch 34, and the plurality of conductive strips 35 are respectively fixedly installed inside the plurality of conductive through holes 202 and in contact with the upper surface of the supporting plate 33.

[0024] In this embodiment, a patch groove is opened inside the conveying groove 201 for embedding and fixing the conductive metal patch 34, so that the conductive metal patch 34 is embedded and fixed inside the conveying groove 201, and the upper surface of the conductive metal patch 34 and the horizontal inner wall of the conveying groove 201 are kept on the same plane.

[0025] More specifically, by providing a conductive metal patch 34, the upper surface of the glass cover and the LCD screen are both in contact with the conductive metal patch 34. When the conveyor belt 2 stops transmitting, the multiple conductive strips 35 at the bottom of the conductive metal patch 34 will contact the supporting plate 33, thereby cooperating with the grounding support frame 1 to complete the grounding, so that the static electricity accumulated on the glass cover and the LCD screen during the transmission process will be conducted through the conductive metal patch 34, the conductive strips 35, the supporting plate 33 and the grounding support frame 1, thereby improving the anti-static effect of the bonding equipment.

[0026] A transfer robot arm mechanism is provided between the two ground support frames 1, and a vacuum suction cup 8 is provided on the transfer robot arm mechanism. The transfer robot arm mechanism is used to drive the vacuum suction cup 8 to transfer the glass cover plate to fit the LCD screen. Figure 1 、 Figure 2 As shown, specifically, the transfer robot arm mechanism includes a rotating platform 4 arranged between two ground support frames 1, a lifting arm 5 is fixedly installed on the top of the driving end of the rotating platform 4, a horizontal telescopic boom 6 is fixedly installed on the telescopic end of the lifting arm 5, and 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 end of the hanger 7, and an adsorption rubber lip 9 is fixedly installed at the bottom of the vacuum suction cup 8. A plurality of evenly distributed negative pressure suction pipes 10 are fixedly installed on the top of the vacuum suction cup 8. The bottom ends of the negative pressure suction pipes 10 all extend to the inside of the adsorption rubber lip 9. The top ends of the plurality of negative pressure suction pipes 10 are fixedly installed with the same multi-way suction pipe 11. A vacuum pump 12 is fixedly installed on one side of the lifting arm 5, and one end of the multi-way suction pipe 11 is connected to the air inlet end of the vacuum pump 12.

[0027] In this embodiment, the rotating table 4 is driven by a servo motor and is divided into a fixed base and a driving end. The fixed base is fixed on the ground or platform, and the driving disk is rotatably assembled inside the fixed base. The driving disk is rotated inside the fixed base by the servo motor and the gear mechanism. Secondly, multiple sets of transfer robot 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. According to the different structures of the LCD segment code screen, another set of mechanical grippers and feeding structures can be added to one side of the lifting arm 5 to place the wiring between the glass cover plate and the LCD screen, so that when the finished product is in use, the static electricity between the glass cover plate and the LCD screen can be grounded and discharged through the wiring.

[0028] More specifically, when the anti-static fully automatic laminating equipment is in use, the cleaned glass cover plate and the LCD screen coated with optical glue on the upper surface are placed in multiple conveying slots 201 on two conveyor belts 2 for transportation. When the two are transferred from the heat preservation tunnel 3 to one side of the transfer robot arm mechanism, the transmission roller stops, and the horizontal telescopic boom 6 drives the vacuum suction cup 8 to move to the top of the glass cover plate. The lifting arm 5 drives the vacuum suction cup 8 and the adsorption glue lip 9 to press down and adhere to the top of the glass cover plate. At this time, the vacuum pump 12 extracts the air inside each negative pressure suction pipe 10 through the multi-way suction pipe 11, and then quickly reduces the pressure. The low vacuum suction cup 8 and the air pressure inside the adsorption lip 9 cause the glass cover plate to be adsorbed on 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 the glass cover plate to move up, and the turntable 4 drives the transfer robot arm mechanism to rotate as a whole to move the glass cover plate to the top of the LCD screen. As the lifting arm 5 contracts, the glass cover plate is attached to the LCD screen. Then the suction is stopped and air is re-supplied to the vacuum suction cup 8 and the adsorption lip 9 to separate the glass cover plate from the adsorption lip 9. Then the transfer robot arm mechanism is reset, and the transfer roller operates again to carry out the next round of bonding, thereby realizing automated bonding.

[0029] like Figure 8As shown, a plurality of evenly distributed support rollers 32 are rotatably installed inside the ground support frame 1. Specifically, the plurality of support rollers 32 are all located inside the conveyor belt 2. A support plate 33 is fixedly installed inside the ground 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.

[0030] More specifically, by providing support rollers 32 and support flat 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 plate and the LCD screen. The support flat plates 33 are also supported inside the conveyor belt 2. When the vacuum suction cup 8 carries the glass cover plate downward, the support flat plates 33 can act as a flat support, making the force on the glass cover plate and the LCD screen more uniform.

[0031] 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-way 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.

[0032] In this embodiment, the vacuum pump 12 and the filter box 36 are both assembled on the fixed end of the lifting arm 5.

[0033] More specifically, by providing a filter box 36, the air inside the vacuum suction cup 8 and the adsorption lip 9 is sucked into the filter box 36 through the multi-way suction pipe 11. Dust mixed in the air will be absorbed and filtered by the adsorption particles inside the filter box 36, thereby reducing the burden on the vacuum pump 12 and achieving the adsorption of dust on the upper surface of the glass cover.

[0034] like Figure 1 、 Figure 7 As shown, an industrial vacuum cleaner 26 is provided on one side of one of the ground 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 dust suction port of the industrial vacuum cleaner 26, and the U-shaped air guide plate 27 faces the upper surface of the conveyor belt 2 on the same side.

[0035] In this embodiment, the industrial vacuum cleaner 26 is arranged on one side of the conveyor belt 2 for transporting the LCD screen, with its suction port facing the LCD screen.

[0036] More specifically, by setting up an industrial vacuum cleaner 26, when the LCD screen is transported to the side of the transfer robot arm mechanism, the floating dust around the LCD screen will be sucked into the dust suction port of the industrial vacuum cleaner 26, preventing the floating dust in the air from falling on the screen or the optical adhesive surface, causing bubbles, looseness and other problems in the bonding.

[0037] like Figure 7 、 Figure 3 As shown, specifically, a plurality of vertically arranged spring telescopic rods 28 are fixedly installed at the bottom of the U-shaped air guide plate 27, and the telescopic ends of the spring telescopic rods 28 extend to the interior of the U-shaped air guide plate 27 and are fixedly installed with the same L-shaped air guide slide 29. The L-shaped air guide slide 29 is slidably installed on one side of the industrial vacuum cleaner 26, and a pressing frame 30 is fixedly installed on the top of the L-shaped air guide slide 29, and an upper pressure rod 31 corresponding to the position of the pressing frame 30 is fixedly installed at the bottom end of the hanger 7.

[0038] More specifically, by providing an L-shaped air guide slide 29, as the vacuum suction cup 8 and the adsorption lip 9 carry the glass cover plate downward, the upper pressure rod 31 above the vacuum suction cup 8 will press the pressing frame 30 from below, causing the pressing frame 30 to slide downward along the U-shaped air guide plate 27, thereby gradually reducing the space between the L-shaped air guide slide 29 and the U-shaped air guide plate 27, and gradually reducing the area of the dust suction port of the industrial vacuum cleaner 26, so that the air flow intensity gradually increases as the glass cover plate and the LCD screen approach, and changes from absorbing floating dust in the surrounding air to directly and strongly adsorbing dust on the bonding surface of the two, ensuring the cleanliness of the bonding surface of the two.

[0039] The negative pressure straw 10 is provided with a touch-pressing mechanism for lightly pressing the glass cover plate for bonding. Figure 4 、 Figure 5 、 Figure 6 As shown, specifically, the touch-pressure mechanism includes a hanging ring 13 fixedly mounted inside the bottom end of the negative pressure straw 10, and a plurality of evenly distributed air holes 1301 are provided on the hanging ring 13. A push rod housing 14 is fixedly inserted into the interior of the hanging ring 13, and 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 straw 10 and is fixedly mounted with a sealing rubber disc 16, which is located at the bottom of the hanging ring 13.

[0040] In this embodiment, one side of the push rod housing 14 extends to the outside of the negative pressure suction tube 10 , and a sealing treatment is performed on the joint between the push rod housing 14 and the negative pressure suction tube 10 .

[0041] More specifically, by providing a touch-and-press mechanism, when the adsorption 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 downward 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 pipe 10 through the vent 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.

[0042] like Figure 4 、 Figure 6 As shown, specifically, a water outlet trough 1601 is provided inside the sealing rubber disc 16, a conductive metal disc 17 is fixedly installed at the bottom of the sealing rubber disc 16, and a circulating 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 end of the circulating pump 18 is fixedly installed on the top of the circulating pump 18, and a water supply network 20 and a return network 21 are fixedly installed on the surrounding sides of the multiple negative pressure suction pipes 10. One end of the water supply network 20 is connected to the water outlet end of the circulating pump 18, and one end of the return network 21 extends to the interior of the circulating pump 18 and is connected to the water storage container 19. An inlet pipe 23 and an outlet pipe 24 are fixedly installed on the side walls of the negative pressure suction pipe 10. The inlet pipe 23 and the outlet pipe 24 are respectively connected to the water supply network 20 and the return network 21. Two water hoses 22 connected to the water outlet trough 1601 are fixedly installed on the top of the sealing rubber disc 16. The top ends of the two water hoses 22 respectively pass through two vents 1301 and are respectively connected to the inlet pipe 23 and the outlet pipe 24.

[0043] In this embodiment, the conductive metal disc 17 is embedded and fixed in an embedding hole opened at the bottom of the sealing rubber disc 16 , and the upper surface of the conductive metal disc 17 is located inside the water outlet groove 1601 .

[0044] More specifically, by providing a conductive metal disc 17, after the sealing rubber disc 16 is bonded to the glass cover plate, the conductive metal disc 17 is also bonded to the glass cover plate. At this time, the circulating pump 18 draws the conductive liquid from the inside of the water storage container 19 and transmits it to each water outlet trough 1601 through the water supply network 20, the water inlet pipe 23, and the water supply hose 22, where it contacts the upper surface of the conductive metal disc 17. The conductive liquid is then transmitted back to the water storage container 19 through the water supply hose 22, the water outlet pipe 24, and the return water network 21, completing the circulation of the conductive liquid. The static electricity accumulated on the glass cover plate is conducted to the water storage container 19 through the flow of the conductive liquid, thereby realizing the static electricity conduction of the glass cover plate and reducing the adhesion of dust on the glass cover plate.

[0045] 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 to the interior of the water storage container 19 .

[0046] In this embodiment, the hanger 7 is equipped with a grounding socket for plugging in the grounding cable 25 .

[0047] More specifically, by providing a grounding cable 25 , static electricity accumulated inside the water storage container 19 can 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 .

[0048] In summary: Before lamination: The cleaned glass cover plate and the LCD screen with optical adhesive coated on the upper surface are placed in multiple conveying slots 201 on two conveyor belts 2 for transportation. When the two are transferred from the heat preservation tunnel 3 to one side of the transfer robot arm mechanism, the conveying roller stops, and the multiple conductive strips 35 at the bottom of the conductive metal patch 34 will contact the supporting plate 33, thereby cooperating with the grounding support frame 1 to complete the grounding. The static electricity accumulated on the glass cover plate and the LCD screen during the transmission process will be conducted through the conductive metal patch 34, the conductive strips 35, the supporting plate 33 and the grounding support frame 1, and the dust around the LCD screen will be sucked into the dust suction port of the industrial vacuum cleaner 26; During bonding: the horizontal telescopic boom 6 drives the vacuum suction cup 8 to move to the top of the glass cover, the lifting arm 5 drives the vacuum suction cup 8 and the adsorption lip 9 to press down and fit on the top of the glass cover, the electric push rod 15 inside the push rod housing 14 will drive the sealing rubber disc 16 to move down and contact the upper surface of the glass cover, the circulation pump 18 circulates the conductive liquid, and the static electricity accumulated on the glass cover is conducted to the water storage container 19 through the flow of the conductive liquid. After the sealing rubber 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 pipe 10 through the vent 1301. At this time, the vacuum pump 12 extracts the air inside each negative pressure suction pipe 10 through the multi-way suction pipe 11, thereby quickly reducing the air pressure inside the vacuum suction cup 8 and the adsorption rubber lip 9, so that the glass cover is adsorbed on the bottom of the adsorption rubber lip 9 under the action of negative pressure, and then the vacuum suction cup 8 and the adsorption rubber lip 9 drive The glass cover moves up, and the rotating platform 4 drives the transfer robot 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 contracts, the glass cover is attached to the LCD screen. As the vacuum suction cup 8 and the adsorption adhesive lip 9 carry the glass cover down, the upper pressing rod 31 above the vacuum suction cup 8 will press the pressing frame 30 from below, so that the pressing frame 30 slides downward along the U-shaped air guide plate 27, thereby gradually reducing the space between the L-shaped air guide slide plate 29 and the U-shaped air guide plate 27, and gradually reducing the area of the dust suction port of the industrial vacuum cleaner 26, so that the airflow intensity gradually increases as the glass cover and the LCD screen get closer, and the airflow changes from absorbing floating dust in the surrounding air to directly and strongly adsorbing dust on the contact surface of the two. The sealing adhesive disc 16 continues to press down and attach to the top of the glass cover, so that the glass cover and the LCD screen are lightly pressed and attached more tightly. After lamination: the vacuum pump 12 stops sucking air and re-supplies air to the vacuum suction cup 8 and the adsorption lip 9, so that the glass cover is separated from the adsorption lip 9. Then the transfer robot arm mechanism is reset, and the transfer roller operates again for the next round of lamination, thereby realizing automated lamination.
