[0001] The invention belongs to the technical field of liquid crystal display screen production, and in particular relates to a panel laminating device for producing LCD liquid crystal display screens. Background Art

[0002] With the continuous advancement of science and technology, more and more touch screen manufacturers have begun to use advanced panel laminating devices to improve production efficiency and product quality. These panel laminating devices not only represent a leap in manufacturing technology, but also greatly meet the market's growing demand for high-definition, high-color saturation and ultra-thin design displays. These advanced laminating devices achieve high-precision, dust-free lamination between LCD panels and backlight modules or other key components through sophisticated mechanical design and automated control technology. They use advanced technologies such as visual positioning systems, precision pressure control, temperature and humidity management, etc., to ensure that each panel can achieve the best display effect and long service life during the laminating process.

[0003] However, due to the complex processes involved in the bonding process and the extremely high precision requirements, any slight deviation or improper operation may lead to increased losses in the panel bonding device, thereby affecting the yield and quality of the product. In addition, most of the related devices currently used have the problem of difficult-to-control losses. This phenomenon has become a problem that needs to be urgently solved by people in this field. Summary of the invention

[0004] The purpose of the present invention is to provide a panel bonding device for producing LCD liquid crystal display screens in order to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A panel bonding device for LCD liquid crystal display production, comprising a support base, an operating platform welded on the top of the support base, and a first installation groove and a second installation groove are formed on the operating platform.

[0010] The positioning plate is adapted to the limiting groove, and both cranks are provided with connecting sleeves. The connecting sleeves are a structure of two hollow cylinders connected to each other.

[0012] According to the above technical solution, the operation steps of the positioning component include:

DETAILED DESCRIPTION

[0033] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The embodiment of the present invention provides a technical solution: a panel laminating device for producing LCD liquid crystal display screens, Figure 1 FIG. 1 is a schematic structural diagram of a panel laminating device for producing an LCD display screen according to an embodiment of the present invention. Figure 1-2 As shown, the panel bonding device for LCD liquid crystal display production includes a support base 1, an operating platform 2 is welded on the upper side of the support base 1, and a first mounting groove 21 and a second mounting groove 22 are formed on the operating platform 2.

[0035] A laminating machine 4 is fixed in the first installation groove 21, and a plurality of touch screens 3 are arranged in the second installation groove 22. The touch screens 3 in the second installation groove 22 are accurately placed by a manipulator. A controller 23 is installed on one side of the operating platform 2. An ion blower 5 is riveted to the upper part of the operating platform 2 near the outer side of the second installation groove 22, and a glue dispenser 6 is riveted to the other outer side of the upper part of the operating platform 2. Four columns 7 are symmetrically welded on the upper part of the operating platform 2, and a fixing plate 8 is welded on the top of the column 7. A camera 1 is installed below the fixing plate 8. An electric guide rail 9 is installed in the center of the fixing plate 8, and an electric telescopic rod 10 is slidably connected to the electric guide rail 9. A vacuum pump 11 is riveted to the end of the electric telescopic rod 10, and a suction cup 12 is connected to the vacuum pump 11 through a pipe. The suction cup 12 is a structure connected and fixed by a vertically distributed pipeline bracket, and each of the suction cups 12 is connected to the vacuum pump 11 through an internal pipeline of the bracket.

[0036] Among them, the laminating machine 4 , the glue dispensing machine 6 , the electric guide rail 9 , the electric telescopic rod 10 , and the vacuum pump 11 are all connected to the controller 23 via signals.

[0037] The substrate to be pasted is placed on the laminating machine 4, and the controller 23 controls the glue dispenser 6 to spray the adhesive on the surface of the substrate. At the same time, the controller 23 drives the electric telescopic rod 10 to extend, thereby controlling the suction cup 12 to contact the touch screen 3 below, and then starts the vacuum pump 11 to extract the air inside the suction cup 12 through the pipe connected to the suction cup 12, thereby reducing the air pressure in the suction cup 12, thereby achieving the adsorption connection between the suction cup 12 and the touch screen 3. After the connection is completed, the electric telescopic rod 10 shrinks and then moves on the electric guide rail 9 until the suction cup 12 moves to the top of the laminating machine 4 and stops, and then extends the electric telescopic rod 10 to place the touch screen 3 on the substrate for lamination.

[0038] In certain preferred embodiments, Figure 3 As shown, the laminating machine 4 includes a base 41, and two positioning grooves 411 are provided on the base 41, and the distance between the positioning grooves 411 and the adjacent wide sides of the base 41 is equal. A conveying plate 42 is installed above the base 41, and the conveying plate 42 is a hollow structure and two single-side closed pipelines are installed inside. Four limiting grooves 421 are provided above the conveying plate 42, and the two limiting grooves 421 located in opposite directions have opposite margins to the two sides of the base 41. Two threaded columns 422 are welded to the bottom of the conveying plate 42, and the threaded columns 422 are rectangular parallelepiped structures, and a threaded hole is provided in the direction of the longer side of the conveying plate 42, and the two threaded columns 422 are symmetrical about the center of the conveying plate 42.

[0039] The base 41 is internally provided with a transport assembly 43, such as Figure 4 As shown, the transport assembly 43 includes a driving rod 431, one end of which is mounted with a rotating motor 432, and the driving rod 431 is sleeved with two driving gears 433 symmetrical about the center of the conveying plate 42, one side of the driving gear 433 is meshedly connected with a driven gear 434, and a screw rod 435 is passed through the center of the driven gear 434, and the screw rod 435 is meshed with a threaded hole on the threaded column 422. After the rotating motor 432 is started by the controller 23, the driving rod 431 will drive the driving gear 433 to rotate, so that the driven gear 434 meshes and rotates, and then the screw rod 435 rotates, and the threaded column 422 will be displaced on the screw rod 435 due to the meshing with the screw rod 435, and finally the displacement effect of the conveying plate 42 is achieved, and then the substrates to be bonded and the bonded substrates can be transported. When the conveying plate 42 is set to move to the transport end point, the center of the conveying plate 42 will be located on the transverse center line of the electric guide rail 9, thereby ensuring that the center position of the substrate is always on the transverse center line of the electric guide rail 9, and the conveying plate 42 moves in the opposite direction of the end point to the end of the positioning groove 411 and is set as the starting point. The stability and reliability of the device are improved by providing the transport component 43.

[0040] In certain preferred embodiments, Figure 4 , 5As shown, a positioning assembly 44 is installed inside the conveying plate 42 for fixing the substrate. The positioning assembly 44 includes a connecting tube 441, which is positioned in the single-sided closed pipeline inside the conveying plate 42, and the connecting tube 441 is connected to the closed end of the single-sided closed pipeline through an electric push rod. A rotating connecting member 442 is welded inside the connecting tube 441. The rotating connecting member 442 is a rod structure that is rotatably connected to the connecting tube 441, and one end of the rotating connecting member 442 is welded with a connecting rod. Rod 443, an electric push rod is installed in the connecting rod 443, a connecting ring 444 is welded to one end of the connecting rod 443 where the electric push rod is installed, two symmetrical cranks 445 are welded in the connecting ring 444, the two ends of the cranks 445 are connected, and a positioning plate 45 is welded to the end of the crank 445, then two positioning plates 45 are provided on one positioning assembly 44, and there is an angle of 90 degrees between the two positioning plates 45, and the vertical surfaces of the two positioning plates 45 forming the 90 degree angle are in contact with the substrate. A pressure sensor 1 is installed inside the upper surface of the positioning plate 45 for detecting the pressure on its upper surface. A pressure sensor 2 is installed inside the surface of the positioning plate 45 that contacts the substrate for detecting the pressure on its inner surface. The maximum displacement distance around the positioning plate 45 is within the size range of the limit groove 421. Both cranks 445 are sleeved with connecting sleeves 446. The connecting sleeves 446 are a structure in which two hollow cylinders are connected by a connecting plate. A disc 447 connected by a connecting rod is inserted into one of the hollow cylinders of the two connecting sleeves 446. The disc 447 is rotatably connected to the hollow interior of the conveying plate 42.

[0041] Two positioning assemblies 44 are installed inside the conveying plate 42. After the electric push rod pushes the connecting cylinder 441 out of the pipeline, the cranks 445 sleeved on the two connecting sleeves 446 will be pressed as shown in the figure. Figure 6 The rotation shown, that is, the hollow cylinder of the connecting sleeve 446 sleeved with the crank 445 will rotate around the hollow cylinder sleeved with the disk 447 connecting rod, so that the positioning plate 45 body will extend out of the limiting groove 421, and the positioning plate 45 will move inward along the surrounding directions of the conveying plate 42, and make its inner surface closely contact with the substrate, and realize the positioning effect after feedback from the pressure sensor 2. When the electric push rod shrinks, the positioning plate 45 will retract below the limiting groove 421 and move from the inner side of the conveying plate 42 to the surrounding outer direction, until the positioning plate 45 is lower than the upper surface of the conveying plate 42, the substrate can be removed. (That is, the movement trajectory of the positioning plate 45 is: rotating around the center of the disk 447 while moving back and forth along the straight line direction of the connecting rod 443.)

[0042] In some optional embodiments, when the conveying plate 42 is located at the starting point, the positioning plate 45 is driven by the positioning component 44 to descend to a position below the upper surface of the conveying plate 42, and the substrate is placed on the conveying plate 42 by means of a conveying crawler or manual delivery. When the conveying plate 42 reaches the end point, the positioning component 44 is started at the same time, so that the positioning plate 45 rises and contacts the surface of the substrate to complete the positioning operation. At the same time, after the suction cup 12 is adsorbed on the touch screen 3, the electric telescopic rod 10 moves on the electric guide rail 9, driving the touch screen 3 to the top of the substrate. At this time, the position to which the suction cup 12 moves is the position set by the initial program. After stopping the displacement, the electric telescopic rod 10 slowly descends until the touch screen 3 and the substrate are completely fitted.

[0043] When the situation that direct bonding is impossible occurs, the lowered electric telescopic rod 10 will cause the touch screen 3 to collide with the upper surface of the positioning plate 45. At this time, the pressure sensor installed in the positioning plate 45 will send a signal to the controller 23, and the electric telescopic rod 10 will stop running. The controller 23 will drive the positioning component 44 to adjust the touch screen 3 adsorbed on the suction cup 12:

[0044] Specifically, Figure 3 As shown, when any one or two positioning plates 45 located on the same positioning assembly 44 feedbacks that the touch screen 3 is in contact with it through the pressure sensor 1, the displacement assembly 44 on the contact side will be started, and the electric push rod will drive the connecting tube 441 to move in the opposite direction of the connecting rod 443, so that the positioning plate 45 is temporarily separated from the substrate, until the inner side of the positioning plate 45 can detect that it is in contact with the touch screen 3 through the pressure sensor 2, and then the connecting tube 441 is driven in another direction by the electric pass, so that the touch screen 3 falls into the range of the substrate, and at this time, the electric telescopic rod 10 will continue to drive down until the touch screen 3 is in contact with the substrate;

[0045] When the two non-opposite positioning plates 45 located on different positioning components 44 report through the pressure sensor that the touch screen 3 is in contact with the two positioning components 44, both positioning components 44 will be activated to move the positioning plates 45 outward by a certain distance and then restore the positioning plates 45 to their original positions, so that the touch screen 3 falls into the range corresponding to the substrate;

[0046] When the two relative positioning plates 45 feedback through the pressure sensor 1 that the touch screen 3 is in contact with them, it means that the size of the touch screen 3 is too large and does not meet the size of the substrate to be bonded. At this time, after receiving the feedback signal from the pressure sensor 1, the controller 23 controls the electric telescopic rod 10 on the electric guide rail 9 to return to the position of adsorbing the touch screen 3, put it back into the second installation groove 22, and send an alarm through the camera 1 to remind the operator to take out the touch screen 3 that does not meet the size.

[0047] After the bonding is completed, the camera 1 will calibrate the LCD screen on the conveying plate 42 to ensure the reliability of the bonding, and then the conveying plate 42 will be moved to the starting point through the transportation component 43 to take out the bonded display screen.

[0048] Based on the above embodiment, the controller 23 sets the number of times that the positioning component 44 can be restarted to adjust the position of the touch screen 3 to N, and the number of times the positioning component 44 is actually restarted to adjust the position of the touch screen 3 is n. When the controller 23 feedbacks that n is greater than N, the camera issues an alarm, and the operator repositions the touch screen 3 in the second mounting groove 22 so that the center of the touch screen 3 is located on the center of the second mounting groove 22 before continuing the fitting operation. Through the above embodiment, while accurately positioning the substrate, targeted measures are taken for the situation where the touch screen 3 is too large to fit the bonding, which reflects the strong functionality of the device.

[0049] In some preferred embodiments, the ion blower 5 includes a bracket and a blower body, and the blower body is movably connected to the bracket, so that the direction of the blower body can be manually adjusted to achieve the static electricity elimination operation of the touch screen 3 placed in the second mounting groove 22, thereby preventing dust in the air from being adsorbed onto the touch screen 3 during the bonding process, thereby reducing the bonding quality.

[0050] In certain preferred embodiments, Figure 7 , 8 As shown, a pressing assembly 13 is provided on the outer side of the suction cup 12, and the pressing assembly 13 includes a mounting frame 131. The mounting frame 131 is a hollow square structure. The inner wall of the mounting frame 131 is riveted to the bracket of the suction cup 12. The four sides of the mounting frame 131 are each equipped with an ejection rod 132, and the ejection rod 132 is driven and ejected by a linear motor. A first pressing plate 133 is installed at the bottom of the ejection rod 132. The first pressing plate 133 is also a hollow square structure. The four sides of the first pressing plate 133 are connected to the second pressing plate 134 by electric push rods, and the lower end surface of the plate body of the second pressing plate 134 is flush with the lower end surface of the first pressing plate 133. A pressure sensor three is installed on the inner side of the bottom of the first pressing plate 133, and a pressure sensor four is installed inside the bottom end of the second pressing plate 134. All pressure sensors are connected to the controller 23 signals.

[0051] In some optional embodiments, the glue dispenser 6 first sprays the adhesive on the substrate placed on the conveying plate 42. After the spraying is completed, the glue dispenser 6 is reset, and the suction cup 12 with the touch screen 3 adsorbed is driven by the electric guide rail 9 to align with the substrate. After the touch screen 3 and the substrate are overlapped and bonded, the vacuum pump 11 is released to allow air to re-enter the suction cup 12, thereby destroying the vacuum state, so that the touch screen 3 and the substrate are bonded. After the bonding is completed, the controller 23 will drive the ejection rod 132 to push the first pressing plate 133 out so that it exceeds the plane where the suction cup 12 is located and then contacts the touch screen 3. After the pressure sensor 3 detects that the first pressing plate 133 is in contact with the touch screen 3, the ejection rod 132 stops being pushed out, and at this time the second pressing plate 134 is driven toward the substrate The edge area is pushed out until the pressure sensor 2 on the inner wall of the positioning plate 45 detects that the second pressing plate 134 is in contact with it, and the second pressing plate 134 located in this direction stops being pushed out. At this time, the pressure sensor 4 on the inner side of the bottom of the second pressing plate 134 provides pressure feedback. When the pressure value is normal, it means that the touch screen 3 is fitted normally. When the pressure value becomes smaller, it means that the touch screen 3 is not fitted properly at this time, so that the edge of the substrate is not completely fitted, and the coverage area of ​​the touch screen 3 is not suitable. The controller 23 issues an alarm, and the operator makes targeted operations after observing the on-site situation through the camera 1 to perform a size inspection for the batch of touch screens 3 to avoid the occurrence of incompatible fitting again.

[0052] The above embodiment completes the screen lamination and also takes a series of measures to address the situation where the touch screen 3 is too small to fit. This complements the situation where the positioning component 44 can only determine that the touch screen 3 is too large, thereby further improving the feasibility of the device, embodying the functionality of the device, and further controlling the loss of the device during use, greatly improving production efficiency and resource utilization.
