Description

Technical Field

[0001] The present invention relates to the technical field of touch screen panel production, in particular to a touch screen panel laminating device. Background Art

[0002] A touch screen panel is an inductive liquid crystal display device that can receive input signals such as contacts. A touch screen panel consists of a touch detection component and a touch screen controller. The touch detection component is installed in front of the display screen to detect the position of the user's touch, and then transmit the information to the touch screen controller; the main function of the touch screen controller is to receive the touch information on the touch point detection device, convert it into touch point coordinates, and then send it to the CPU. It can also receive commands from the CPU and execute them. Touch screens can be divided into resistive, capacitive, infrared and surface acoustic wave touch screens according to the type of sensor. Among them, resistive touch screens use pressure sensing for control, while capacitive touch screens are positioned through the coupling capacitance formed by the human body's electric field and the working surface. Touch screen technology is widely used in many fields such as mobile phones, tablet computers, retail, public information inquiry, multimedia information systems, medical instruments, and industrial automatic control.

However, the fixation of the control panel relies on single-sided clamping, which cannot guarantee its stability and accuracy.

[0040] refer to Figure 2 The positioning block 102 is used to provide a side positioning for the control panel part to ensure the stability and accuracy of the placement of the control panel, and the polished rod 103 is used to ensure the accuracy of the bonding operation.

[0041] The clamping unit 2 is installed on the supporting frame 101. The clamping unit 2 includes a two-way cylinder 201 fixedly installed on the bottom of the supporting frame 101. Both output ends of the two-way cylinder 201 are provided with a connecting mechanism.

A sliding member 203 that slidably cooperates with the reserved slide groove 106 is fixedly connected to the driving sleeve 202. A moving frame 204 is fixedly connected to the upper part of the sliding member 203. A clamping member 205 for providing transverse and longitudinal clamping forces is symmetrically provided on the upper part of the connecting mechanism.

[0042] refer to Figure 3 Under the action of the external air source, the bidirectional cylinder 201 drives the connecting mechanisms on both sides to approach each other, providing clamping force for clamping, and the reserved slide groove 106 is used to guide the movement of the connecting mechanism to ensure the stability of the connecting mechanism.

[0043] The clamping member 205 includes a clamping box 2051, a side of the clamping box 2051 close to the mobile frame 204 is fixedly connected to a buffer rod 2058, the buffer rod 2058 passes through the mobile frame 204, and an end block 2057 is fixedly connected to the end thereof, a buffer spring 2056 is sleeved on the buffer rod 2058 and located between the mobile frame 204 and the clamping box 2051, a slide rod 2052 is slidably connected in the clamping box 2051, and the outer end of the slide rod 2052 is fixedly connected to the mobile frame 204. A clamping block 2059 is fixedly connected, a clamping wheel 2060 is rotatably installed in the clamping block 2059, a guiding inclined surface 2061 is provided on the clamping block 2059, a tension spring 2053 is fixedly connected to the inner end of the slide bar 2052, the other end of the tension spring 2053 is fixedly connected to a slider 2054, an adjusting screw 2055 is rotatably installed on the slider 2054, the adjusting screw 2055 passes through the side wall of the clamping box 2051, and is threadedly connected to each other;

[0044] refer to Figure 3 , Figure 4 Under the action of the clamping force, the clamping box 2051 can provide a lateral clamping force to the side of the control panel product. The buffer spring 2056 can provide a buffer when the lateral clamping force is too large to avoid damaging the control panel and improve product quality. At the same time, under the drive of the lateral force, the guiding slope 2061 of the clamping wheel 2060 first contacts the side of the control panel, and the tension spring 2053 is stretched under the force. The guiding slope 2061 can provide a guiding effect, and then the clamping wheel 2060 contacts the side of the control panel. Under the action of the elastic force of the tension spring 2053, the clamping wheel 2060 can fit tightly against the side of the control panel, thereby providing a longitudinal clamping force. The clamping force in both the lateral and longitudinal directions can ensure the stability of the control panel, thereby improving the accuracy and sufficiency of subsequent gluing.

[0045] The gluing unit 3 is installed on the supporting chassis 101. The gluing unit 3 includes a gluing frame 301 fixedly installed on the supporting chassis 101. A containing box 309 is fixedly connected to the gluing frame 301. A liquid blocking protrusion 312 is fixedly connected to the inner bottom wall of the containing box 309. A cover 308 is symmetrically installed on one side of the containing box 309 away from the gluing frame 301. A gluing member 307 for gluing is provided in the containing box 309. The gluing member 307 includes a cleaning shielding frame 3072. A glue roller 3071 is rotatably installed in the cleaning shielding frame 3072.

[0046] refer to Figure 5 The liquid blocking protrusion 312 is used to block the glue liquid and prevent the glue liquid from flowing out from the opening of the storage box 309. The cleaning shield 3072 provides shielding and protection when the glue roller 3071 is retracted to prevent the glue from being contaminated by external dust, thereby ensuring that the glue roller 3071 can be used for normal gluing. In the gluing state, the lower surface of the cleaning shield 3072 can wipe and clean the glue-coated surface of the control panel to improve the adequacy of the glue and the control panel to avoid bubbles and other undesirable phenomena due to impurities after bonding, thereby improving the quality of product bonding. The lower surface of the cleaning shield 3072 can increase the cleaning effect by adding a cleaning gasket.

[0047] A lateral movement assembly is provided on the side of the glue coating rack 301 away from the containing box 309, and the lateral movement assembly includes a glue coating cylinder 303 fixedly mounted on the glue coating rack 301, and a guide rod 302 is fixedly connected to the cleaning shielding frame 3072, and the guide rod 302 passes through the glue coating rack 301 and is slidably connected to each other; the glue supply assembly includes a glue pump 305, a dispersion box 304 and a glue box 306 fixedly mounted on the glue coating rack 301, and the liquid extraction end of the glue pump 305 is connected to the glue box 306, and the liquid discharge end of the glue pump 305 is connected to the glue box 306. The dispersion boxes 304 are interconnected, the dispersion boxes 304 and the containing boxes 309 are interconnected, and the dispersion boxes 304 and the containing boxes 309 are connected at multiple points; the blocking assembly includes a blocking block 310 vertically slidably installed in the cover body 308, a blocking spring 311 is fixedly connected between the blocking block 310 and the cover body 308, the transverse movement assembly drives the glue coating member 307 to reciprocate laterally, the glue coating frame 301 is provided with a glue supply assembly for providing glue, and the cover body 308 is provided with a blocking assembly for blocking the glue roller 3071;

[0048] refer to Figure 5 , Figure 6 , Figure 7, the glue pump 305 is powered on to work, the glue liquid in the glue box 306 is extracted, and the glue is evenly dispersed into the containing box 309 through the dispersion box 304, so that the glue is evenly applied to the rubber roller 3071. Under the action of the external air source, the glue cylinder 303 drives the cleaning shield 3072 and the rubber roller 3071 to move. The rubber roller 3071 first contacts the liquid blocking protrusion 312, and the liquid blocking protrusion 312 applies pressure to the rubber roller 3071, so that the excess glue on the rubber roller 3071 is squeezed out. The angle between the side of the liquid blocking protrusion 312 close to the rubber roller 3071 and the horizontal plane is 120° to 140°, so as to avoid the rubber roller 30 The height difference when 71 passes through the liquid blocking protrusion 312 is too large, which ensures the smooth movement of the rubber roller 3071 and prevents the glue from flowing out. Then it contacts the blocking block 310. The longitudinal section of the blocking block 310 close to the rubber roller 3071 is an isosceles triangle. Under the action of the inclined surface of the blocking block 310, the blocking block 310 moves up to squeeze the blocking spring 311. The reaction force of the blocking block 310 is applied to the rubber roller 3071, which performs secondary squeezing on the rubber roller 3071 to avoid too much glue adhering to the rubber roller 3071, which causes the glue to flow around during the coating process, thereby improving the quality of the glue coating.

[0049] A feeding unit 4 is installed on the supporting top frame 104. The feeding unit 4 can horizontally transport the panel products to be bonded. The feeding unit 4 includes a feeding cylinder 401 fixedly installed on the supporting top frame 104. The output end of the feeding cylinder 401 is fixedly connected with an L-shaped feeding frame 402. The feeding frame 402 is fixedly connected with a feeding rod 404. The feeding rod 404 passes through the supporting top frame 104 and is slidably connected to each other. A feeding trough 405 is provided at the lower part of the feeding frame 402. Locking pieces 403 are provided on both sides of the bottom of the feeding trough 405.

[0050] refer to Figure 8 Under the action of the external air source, the feeding cylinder 401 drives the feeding rack 402 to move. When the feeding rack 402 is on the outside, the screen panel can be placed into the feeding slot 405 from the opening of the feeding rack 402. The feeding slot 405 can limit the screen panel to ensure the accurate position of the screen panel. When the feeding rack 402 is on the inside, it can easily adsorb the screen panel to realize the function of automatic feeding.

[0051] The locking member 403 includes an electromagnet 4031 fixedly mounted on the loading rack 402, a permanent magnet 4032 is provided on the magnetic side of the electromagnet 4031, a reset rod 4034 is fixedly connected to the permanent magnet 4032, a reset spring 4033 is sleeved on the reset rod 4034 and located on the outer side of the loading trough 405, the reset rod 4034 passes through the side wall of the loading trough 405, and a locking block 4035 is fixedly connected to the end thereof, and the permanent magnet 4032 has opposite magnetic properties to the electromagnet 4031 after being energized;

[0052] refer to Fig. 9During the locking operation, the electromagnet 4031 is energized and the magnetic side of the electromagnet 4031 generates magnetism, and uses the magnetic force to push the permanent magnet 4032 to move toward the upper material trough 405 side, so that the locking block 4035 moves to the outside of the screen panel. The locking block 4035 at one end first restricts the screen panel, and the locking block 4035 at the other end locks the screen panel to ensure the stability of the screen panel and prevent the screen panel from moving during the movement. When the electromagnet 4031 is powered off, the magnetism of the electromagnet 4031 disappears, and under the action of the reset spring 4033, the locking block 4035 is reset again, thereby not affecting the reset movement of the loading rack 402.

[0053] The laminating unit 5 is located at the top of the supporting unit 1. The laminating unit 5 includes a vertical movement component and an adsorption component. The vertical movement component can drive the adsorption component to move vertically, and the adsorption component can adsorb and fix the panel product conveyed by the loading unit 4; the vertical movement component includes a laminating cylinder 503 fixedly mounted on the supporting top frame 104, the output end of the laminating cylinder 503 passes through the supporting top frame 104, and is fixedly connected to a laminating frame 501, and a sliding sleeve 502 is fixedly mounted on the laminating frame 501; the adsorption component includes a laminating suction cup 504 fixedly mounted on the laminating frame 501, and a vacuum pump fixedly mounted on the supporting top frame 104, and a reserved channel 105 is provided on the supporting top frame 104, the laminating suction cup 504 and the vacuum pump are connected to each other through an air pipe passing through the reserved channel 105, and the light rod 103 passes through the sliding sleeve 502, and they are in sliding fit with each other.

[0054] refer to Fig.10 The vacuum pump generates negative pressure at the bonding suction cup 504 to absorb the screen panel. Then, the bonding cylinder 503, under the action of the external air source, drives the bonding frame 501, the bonding suction cup 504, and the screen panel to move down and bond them to the control panel, so that the two are tightly bonded together by glue to complete the bonding operation. The bonding frame 501 can be provided with a load-reducing hole to reduce the mass of the bonding frame 501 to improve the overall load capacity.

[0055] Working principle: When in use, place one end of the control panel on the supporting frame 101, so that the control panel and the positioning block 102 fit closely together to play a role in preliminary positioning. Then, the two-way cylinder 201, under the action of the external air source, drives the connecting mechanisms on both sides to approach each other to provide clamping force for clamping. The reserved slide groove 106 is used to guide the movement of the connecting mechanism to ensure the stability of the connecting mechanism. Under the action of the clamping force, the clamping box 2051 can provide lateral clamping force to the side of the control panel product. The buffer spring 2056 can provide buffering when the lateral clamping force is too large to avoid damage to the control panel. The panel improves product quality. At the same time, the clamping wheel 2060 is driven by the lateral force, and the guiding inclined surface 2061 first contacts the side of the control panel. The tension spring 2053 is stretched under the force, and the guiding inclined surface 2061 can provide a guiding effect. Then the clamping wheel 2060 contacts the side of the control panel. Under the elastic force of the tension spring 2053, the clamping wheel 2060 can fit closely to the side of the control panel, thereby providing a longitudinal clamping force. The clamping force in both the lateral and longitudinal directions can ensure the stability of the control panel, thereby improving the accuracy and sufficiency of subsequent gluing.

[0056] The glue pump 305 is powered on to work, and the glue liquid in the glue box 306 is extracted and evenly dispersed into the containing box 309 through the dispersion box 304, so that the glue is evenly applied to the rubber roller 3071. Under the action of the external air source, the glue cylinder 303 drives the cleaning shield 3072 and the rubber roller 3071 to move. The rubber roller 3071 first contacts the liquid blocking protrusion 312, and the liquid blocking protrusion 312 applies pressure to the rubber roller 3071, so that the excess glue on the rubber roller 3071 is squeezed out, and then contacts the blocking block 310. Under the action of the inclined surface of the blocking block 310, the blocking block 310 moves up to squeeze the blocking spring 311, and the reaction force of the blocking block 310 is applied to the rubber roller 3071, so that the rubber roller 3071 is pressed. The second extrusion is performed to prevent excessive glue from adhering to the rubber roller 3071, which causes the glue to flow around during the coating process, thereby improving the quality of the glue coating. When the rubber roller 3071 is retracted, the cleaning shield 3072 provides shielding and protection to prevent the glue from being contaminated by external dust, thereby ensuring that the rubber roller 3071 can be used for normal glue coating. In the glue coating state, the lower surface of the cleaning shield 3072 can wipe and clean the glue coating surface of the control panel to improve the adequacy of the glue and the control panel, and avoid the occurrence of bubbles and other undesirable phenomena due to impurities after bonding, thereby improving the quality of product bonding. The lower surface of the cleaning shield 3072 can increase the cleaning effect by adding a cleaning gasket;

[0057] Initially, the loading rack 402 is on the outside, and the screen panel can be placed into the loading trough 405 from the opening of the loading rack 402. The loading trough 405 can limit the screen panel to ensure the accurate position of the screen panel. During the locking operation, the electromagnet 4031 is energized to work, and the magnetic side of the electromagnet 4031 generates magnetism, and uses the magnetic force to push the permanent magnet 4032 to move to the upper trough 405 side, so that the locking block 4035 moves to the outside of the screen panel. The locking block 4035 at one end first limits the screen panel, and the locking block 4035 at the other end locks the screen panel to ensure the stability of the screen panel and avoid the screen panel from moving during the movement. The loading cylinder 401 is under the action of the external air source , driving the loading rack 402 to move inward, the vacuum pump generates negative pressure at the bonding suction cup 504 to adsorb the screen panel. After the screen panel is adsorbed, when the electromagnet 4031 is powered off, the magnetism of the electromagnet 4031 disappears, and under the action of the reset spring 4033, the locking block 4035 is reset again, thereby not affecting the reset movement of the loading rack 402. Then, under the action of the external air source, the bonding cylinder 503 drives the bonding rack 501, the bonding suction cup 504, and the screen panel to move down and fit on the control panel, so that the two are tightly bonded together by glue to complete the bonding operation. A load-reducing hole can be provided on the bonding rack 501 to reduce the mass of the bonding rack 501 and improve the overall load capacity.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
