Description

Technical Field

[0001] This utility model belongs to the field of display panel manufacturing technology, and specifically relates to a vacuum adjustment and alignment tooling for display panels. Background Technology

[0002] This specialized equipment is designed to achieve high-precision alignment of display panels during the production process. Its core function is to control the alignment deviation between the display panel and the component to be bonded to the micrometer level through the coordinated operation of mechanical positioning, vacuum fixing, and visual calibration. It is a key device to ensure product yield in the modular production of display panels.

[0003] Patent publication number CN222874614U discloses a vacuum adjustment and alignment fixture for a display panel, including a rotating mounting platform and a slide fixed on the rotating mounting platform. A slider is slidably mounted on the slide, and a vacuum adsorption module is mounted on the slider. The vacuum adsorption module has several vacuum pinholes for adsorption. The rotating mounting platform also has an adjustable support frame, on which multiple vacuum nozzles located on both sides of the vacuum adsorption module are mounted. The planar structure of the vacuum adsorption module contacts the detection area of ​​the flexible display panel, and the evenly distributed vacuum pinholes generate negative pressure for adsorption and positioning, so that the detection area can remain flat and undeformed, improving detection accuracy. After the support frame is adjusted to adapt to the area of ​​the display panel, the multiple vacuum nozzles are used to grip the display panel parts outside the detection area, reducing deformation of other parts.

[0004] However, the current pressing devices used for polyurethane shock-absorbing pad foaming have the following problems: When using vacuum pinhole adsorption for large-size panels, there is an edge force attenuation phenomenon, and the weight of the panel itself will exacerbate the force difference between the center and the edge. If there is no vacuum nozzle to strengthen the adsorption at the four corners, the center of the panel may be sunken due to excessive force, and the edges may be lifted due to insufficient force, forming an arc-shaped bend. This deformation will lead to a decrease in the subsequent bonding effect. Therefore, we propose a vacuum adjustment and alignment fixture for display panels. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum adjustment and alignment fixture for display panels, which can solve the problem of edge force attenuation when using vacuum pinhole adsorption for large-size panels in related technologies. Furthermore, the weight of the panel itself will exacerbate the force difference between the center and the edge. If there is no vacuum nozzle to strengthen the adsorption at the four corners, the center of the panel may be sunken due to excessive force, and the edges may be lifted due to insufficient force, forming an arc-shaped bend. This deformation will lead to a decrease in the subsequent bonding effect.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A display panel vacuum adjustment and alignment fixture includes an X-rail, an L-plate at the output end of the X-rail, a Y-rail fixed at the bottom of the L-plate, a connecting seat at the output end of the Y-rail, a fixed end of a motor fixed at the inner wall of the connecting seat, a rotating seat fixed at the output end of the motor, an adsorption mechanism at the bottom of the rotating seat, the adsorption mechanism including a connecting button fixed at the bottom of the rotating seat, a placement plate fixed at the bottom of the connecting button, an air pump at the top of the placement plate, a receiving plate fixed at the bottom of the placement plate, and a vacuum pinhole at the bottom of the receiving plate, the vacuum pinhole communicating with the air pump.

[0008] The fixed end of the electric push rod is fixedly installed inside the placement plate, and the output end of the electric push rod is fixedly installed with a receiving button.

[0009] The number of electric push rods, receiving buttons and T-shaped seats is set to four, and they are arranged in a circumferential array along the circumference of the rotating seat. The number of air pumps is set to two, and they are symmetrical along the vertical central axis of the rotating seat.

[0010] A T-shaped seat is fixedly installed on the inner wall of the receiving button, and a vacuum nozzle is provided at the bottom of the T-shaped seat.

[0011] The number of vacuum nozzles is set to five, and they are arranged in a circumferential array along the circumference of the T-shaped seat. The vacuum nozzles are connected to the air pump.

[0012] The surface of the placement plate is provided with a centering mechanism, which includes a cylinder, and the fixed end of the cylinder is fixedly installed on the inner wall of the placement plate.

[0013] A connecting plate is fixedly installed at the output end of the cylinder, and a push plate is fixedly installed on the surface of the connecting plate. The number of cylinders, connecting plates, and push plates is set to two, and they are symmetrical along the vertical central axis of the rotating seat. The push plate is made of rubber.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes an adsorption mechanism that aligns with the display panel when it reaches a designated position. Upon reaching above the display panel, the mechanism adheres to the panel via vacuum pinholes. Since the display panel is thin and has poor deformation resistance, the array of vacuum pinholes disperses the negative pressure adsorption force across hundreds of tiny contact points, preventing damage to the display layer caused by localized stress concentration. Simultaneously with the vacuum pinhole adsorption, vacuum nozzles provide auxiliary adsorption at the four corners of the display panel. The adsorption force of the vacuum pinholes slightly decreases with distance from the air source, resulting in insufficient adsorption at the edges of the display panel. The enhanced adsorption at the four corners compensates for this edge attenuation. For larger display panels, the output of an electric push rod moves a receiving button, which in turn moves a T-shaped seat, which in turn moves the vacuum nozzles, enabling auxiliary adsorption for display panels of different sizes.

[0016] This invention, through the setting of a centering mechanism, allows the connecting plate to move by the retraction of the cylinder output end before the adsorption mechanism adsorbs the panel. The movement of the connecting plate causes the push plate to contact the edge of the display panel, so that the display panel is centered by the push plates on both sides, making it the exact center of the adsorption mechanism. If the initial position of the panel is skewed, the edge may extend beyond the edge of the adsorption platform. During subsequent multi-axis adjustments, it is easy to collide with the guide rails and other components of the tooling. The centering of the push plate ensures that the edge of the panel maintains a safe distance from the edge of the platform. In conjunction with the rubber material design of the push plate, it avoids scratching the edge of the panel during the pushing process. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a vacuum adjustment and alignment fixture for a display panel includes an X-guide rail 1. An L-connecting plate 2 is provided at the output end of the X-guide rail 1. A fixed end of a Y-guide rail 3 is fixedly mounted at the bottom of the L-connecting plate 2. A connecting seat 4 is provided at the output end of the Y-guide rail 3. A fixed end of a motor 5 is fixedly mounted on the inner wall of the connecting seat 4. A rotating seat 6 is fixedly mounted at the output end of the motor 5. A suction mechanism 7 is provided at the bottom of the rotating seat 6. The suction mechanism 7 includes a connecting button 70, which is fixedly mounted at the bottom of the rotating seat 6. A mounting base is fixedly mounted at the bottom of the connecting button 70. The plate 71 has an air pump 72 on its top and a receiving plate 73 fixedly installed on its bottom. The bottom of the receiving plate 73 has a vacuum pinhole 74 connected to the air pump 72. While the vacuum pinhole 74 is adsorbing, the vacuum nozzle 78 assists in adsorbing at the four corners of the display panel. The adsorption force of the vacuum pinhole 74 will decrease slightly with the distance from the air source, resulting in insufficient adsorption force at the edges of the display panel. The enhanced adsorption of the vacuum nozzle 78 at the four corners can compensate for this edge attenuation.

[0026] The fixed end of the electric push rod 75 is fixedly installed inside the placement plate 71, and the output end of the electric push rod 75 is fixedly installed with a receiving button 76, so that it can assist in adsorption when facing display panels of different sizes.

[0027] The number of electric push rods 75, receiving buttons 76 and T-shaped seats 77 is set to four, and they are arranged in a circumferential array along the circumference of the rotating seat 6. The number of air pumps 72 is set to two, and they are symmetrical along the vertical central axis of the rotating seat 6.

[0028] A T-shaped seat 77 is fixedly installed on the inner wall of the receiving button 76. A vacuum nozzle 78 is provided at the bottom of the T-shaped seat 77, so that the vacuum nozzle 78 can assist in adsorption at the four corners of the display panel.

[0029] The number of vacuum nozzles 78 is set to five, and they are arranged in a circumferential array along the circumferential surface of the T-shaped seat 77. The vacuum nozzles 78 are connected to the air pump 72.

[0030] According to the above structure, when the display panel reaches the designated position, the L connecting plate 2 is moved by the X guide rail 1. The movement of the L connecting plate 2 moves the fixed end of the Y guide rail 3, which in turn moves the connecting seat 4. The movement of the connecting seat 4 moves the fixed end of the motor 5, which in turn moves the rotating seat 6. The movement of the rotating seat 6 moves the entire adsorption mechanism 7, aligning the position of the adsorption mechanism 7 with the display panel. This movement of the connecting button 70 moves the placement plate 71, which, upon reaching above the display panel, adheres to the display panel through vacuum pinholes 74. Since the display panel is thin and has poor deformation resistance, the vacuum pinholes 74, distributed in an array, distribute negative pressure... The adsorption force is distributed across hundreds of tiny contact points, avoiding damage to the display layer caused by localized stress concentration. While the vacuum pinhole 74 adsorbs, the vacuum nozzle 78 assists in adsorption at the four corners of the display panel. The adsorption force of the vacuum pinhole 74 will slightly decrease with distance from the air source, resulting in insufficient adsorption force at the edges of the display panel. The enhanced adsorption of the vacuum nozzles 78 at the four corners can compensate for this edge attenuation. For some large-sized display panels, the output end of the electric push rod 75 can drive the receiving button 76 to move. The movement of the receiving button 76 drives the T-shaped seat 77 to move, and the T-shaped seat 77 drives the vacuum nozzle 78 to move, so that auxiliary adsorption can be achieved when facing display panels of different sizes.

[0031] like Figure 1-5 As shown, a centering mechanism 8 is provided on the surface of the placement plate 71. The centering mechanism 8 includes a cylinder 80, and the fixed end of the cylinder 80 is fixedly installed on the inner wall of the placement plate 71.

[0032] A connecting plate 81 is fixedly installed at the output end of the cylinder 80, and a push plate 82 is fixedly installed on the surface of the connecting plate 81. The number of cylinder 80, connecting plate 81 and push plate 82 is set to two, and they are symmetrical along the vertical central axis of the rotating seat 6. The push plate 82 is made of rubber, so that the display panel is centered by the push plates 82 on both sides, so that it is in the center of the adsorption mechanism 7. If the initial position of the panel is skewed, the edge may exceed the edge of the adsorption platform. During subsequent multi-axis adjustment, it is easy to collide with the guide rails and other components of the tooling. The push plate 82 is used to center the panel to ensure that the edge of the panel and the edge of the platform are kept at a safe distance. The rubber material design of the push plate 82 avoids scratching the edge of the panel during the pushing process.

[0033] According to the above structure, before the adsorption mechanism 7 adsorbs, the output end of the cylinder 80 can retract to drive the connecting plate 81 to move. The movement of the connecting plate 81 causes the push plate 82 to contact the edge of the display panel, so that the display panel is centered by the push plates 82 on both sides, making it in the exact center of the adsorption mechanism 7. If the initial position of the panel is skewed, the edge may exceed the edge of the adsorption platform. During subsequent multi-axis adjustment, it is easy to collide with the guide rails and other components of the tooling. The push plate 82 is centered to ensure that the edge of the panel and the edge of the platform maintain a safe distance. In conjunction with the rubber material design of the push plate 82, the edge of the panel is prevented from being scratched during the pushing process.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
