Description

Technical Field

[0001] The present invention relates to the technical field of display screen processing equipment, and in particular to an alignment and pressing equipment for processing a naked-eye 3D display screen and a processing technology thereof. Background Art

[0002] Naked-eye 3D (English: Autostereoscopy) is a general term for technologies that achieve stereoscopic visual effects without the help of external tools such as polarized glasses. The representatives of this type of technology are mainly light barrier technology and cylindrical lens technology. Whether it is light barrier technology or cylindrical lens technology, it needs to be completed through a display screen. The display screen, in simple terms, is LED (Large Electronic Display). The display screen is composed of a number of display units (unit display panels or unit display boxes) that can be combined and spliced ​​to form a screen body, plus a set of appropriate controllers (main control board or control system). Therefore, display panels (or unit boxes) of various specifications can be combined with controllers of different control technologies to form many kinds of LED display screens to meet the needs of different environments and different display requirements. The display screen is mostly divided into double-layer boards, the upper board is a glass panel, and the lower board is a light-emitting panel. Therefore, when processing the display screen, the upper and lower boards need to be aligned and pressed together to complete the processing of the entire display screen.

[0003] Currently, the pressing process of display screens is mostly completed by electronically controlled machines. However, the current electronically controlled machines cannot adapt to a variety of display screen sizes, resulting in processing difficulties. At the same time, the fixing structure of the upper and lower plates is relatively complicated, resulting in difficulty in disassembly and assembly, which greatly reduces production efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A positioning and pressing device for processing a naked-eye 3D display screen, comprising a base plate, support frames are symmetrically fixedly installed on both sides of the upper surface of the base plate, a preset frame is arranged inside the support frame, the preset frame is fixedly connected to the upper surface of the base plate, and a pressing frame is fixedly connected to the side of the upper surface of the base plate away from the preset frame, wherein the upper surfaces of the preset frame and the pressing frame are arranged in a stepped shape, and further comprising:

[0006] A positioning mechanism, which is fixedly mounted on the top of the support frame and is used to adjust its own opening and closing range to match the upper plate of the display screen;

[0007] A pressing mechanism, which is fixedly mounted at the lower end of the positioning mechanism and is also arranged above the pressing frame, and is used to cooperate with the positioning mechanism to align and press the display screen;

[0008] The positioning mechanism includes a connecting plate, which is fixedly connected to the top of the support frame. The connecting plate is provided with two pieces, and a driving rod is rotatably connected between the two connecting plates. The driving rod is provided as a threaded rod, and the output end of the driving rod is rotatably connected to a motor. Matching rods are provided on both sides of the driving rod. The motor is fixedly installed on the outer surface of the connecting plate, and the matching rod and the driving rod are provided in the same horizontal plane. The two ends of the matching rod are fixedly connected to the inner surface of the connecting plate, and the outer surface of the driving rod is threadedly connected to a movable plate, and the movable plate is also slidably connected to the outer surface of the matching rod.

[0009] The bottom surface of the movable plate is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a pushing block, the bottom of the pushing block is fixedly plugged with a connecting rod, the end of the connecting rod away from the pushing block is fixedly connected to a mounting frame, the mounting frame is cross-shaped, and the upper surface of the mounting frame is symmetrically provided with sliding grooves, wherein four sliding grooves are provided, and the pressing mechanism is slidably connected in the sliding grooves through a spring.

[0010] Preferably, the outer surface of the connecting rod is slidably sleeved with a first sleeve, the outer surface of the first sleeve is rotatably connected to a transmission belt, the end of the transmission belt away from the first sleeve is rotatably connected to a second sleeve, the bottom of the second sleeve is rotatably connected to an extension plate, the end of the extension plate away from the second sleeve is fixedly connected to the side of the mounting frame, and the top of the second sleeve is fixedly connected to a rotating handle.

[0011] Preferably, the bottom end of the first sleeve is fixedly connected to a stabilizing frame, wherein the stabilizing frame is arranged in a cross shape, and the outer end of the stabilizing frame is fixedly connected to a driving frame, wherein the driving frame is arranged in a four-pointed star shape, and the outer end of the driving frame is slidably connected to the top outer surface of the pressing mechanism, and the driving frame is also rotatably sleeved on the bottom outer surface of the connecting rod. When the display screen needs to be pressed, the upper plate can be placed in the preset frame, and the lower plate can be placed in the pressing frame at the same time, and the motor can be started at the same time, and the driving rod can be driven by the motor to rotate, that is, the moving plate is driven to move above the preset frame on the driving rod and the matching rod. When the moving plate moves to just above the preset frame, the hydraulic cylinder is driven, and under the drive of the hydraulic cylinder, the pushing block starts to move downward close to the preset frame, that is, the positioning mechanism and the pressing mechanism below the pushing block are close. Preset frame, when the positioning mechanism and the pressing mechanism are located above the preset frame, the first sleeve can be caused to start rotating by rotating the handle, which means that the mounting frame starts to rotate. When the mounting frame starts to rotate, the pressing mechanism will be driven to move relatively close to the mounting frame, thereby reducing and expanding the coverage of the pressing mechanism. When the size adjustment is completed, the hydraulic cylinder is continued to be driven to cause the pressing mechanism to move downward and adsorb the upper plate. When the upper plate is adsorbed, the hydraulic cylinder is driven in the reverse direction to cause the upper plate to leave the preset frame, and the motor is started in the reverse direction at the same time to drive the moving plate to approach the pressing frame. When the moving plate moves to the top of the pressing frame, the hydraulic cylinder is driven again to cause the pressing mechanism to move downward and finally fit the upper plate to the upper surface of the lower plate, and the pressing of the display screen is completed by pressing.

[0012] Preferably, the pressing mechanism includes a sliding rod, the top end of the sliding rod is slidably connected in the sliding groove through a spring, the bottom outer surface of the sliding rod is slidably connected with a ring, the bottom inner surface of the ring is slidably connected with an extrusion rod, the bottom of the extrusion rod is fixedly connected with a mounting tube, the bottom inner surface of the mounting tube is slidably connected with an extrusion column, and the bottom of the extrusion column is fixedly connected with a rubber ring.

[0013] Preferably, a through hole is reserved through the upper surface of the extrusion column, and a first elastic telescopic rod is fixedly connected to the edge of the upper surface of the extrusion column, and a positioning ring is fixedly connected to the top of the first elastic telescopic rod, and the positioning ring is fixedly connected to the inner surface of the mounting tube, and a support ring is arranged above the positioning ring, and the support ring is fixedly connected to the inner surface of the top end of the mounting tube, wherein six supports are arranged at fixed intervals around the central axis, and a pressure relief rod is slidably sleeved on the support ring through a spring, and one end of the pressure relief rod away from the support ring is slidably penetrated and connected to the outer surface of the top end of the mounting tube, and a connecting groove is arranged through the outer surface of the pressure relief rod, wherein the connecting groove is initially located in the mounting tube under the action of elastic force.

[0014] Preferably, a friction plate is fixedly connected to the inner surface of the pressure relief rod, and six friction plates are provided. The six friction plates are combined into a circular ring shape. A pressure block is fixedly connected to the middle of the upper surface of the extrusion column, and the top side of the pressure block is set to an arc shape. An electromagnet is provided on the pressure block, and the outer surface of the pressure block is set to be smooth.

[0015] Preferably, the interior of the rubber ring is set to be hollow, and the inner surface of the rubber ring is symmetrically fixedly connected with an elastic ring, the cross-section of the elastic ring is set to be arc-shaped, and the surface of the elastic ring is provided with air holes at fixed intervals around the central axis, and the air holes are also set through the rubber ring. When the pressing mechanism is close to the upper plate, the rubber ring at its lower end will first contact the upper plate. When the rubber ring is close to the upper plate, the driving of the hydraulic cylinder will make the extrusion column move into the installation tube under the action of pressure, thereby increasing the air pressure inside the installation tube. When the air pressure increases to a certain extent, it will drive the pressure relief rod to move outward in the installation tube, and then connect the inside and outside of the installation tube through the connecting groove on the pressure relief rod, so that the air pressure inside the installation tube drops to a normal level. When the hydraulic cylinder is driven in the reverse direction, the extrusion column will move outward of the installation tube under the elastic force of the first elastic telescopic rod, thereby making the inside of the installation tube in a negative pressure state, and then the upper plate is adsorbed through the rubber ring at the bottom, which is convenient for transportation. When the upper plate is moved to the top of the lower plate and the upper plate and the lower plate are attached to each other, the hydraulic cylinder can be driven again to promote The pushing block continues to move downward, that is, continues to apply extrusion force to the upper plate, presses the upper plate and the lower plate together, and during the pressing process, the extrusion column continues to move upward in the installation tube, thereby causing the pressure block on the extrusion column to move upward and gradually contact with the friction plate, and by setting the upper end side of the pressure block to be inclined, the pressure relief rod is pushed gradually to the outside of the installation tube under the action of pressure, thereby connecting the inside and outside of the installation tube again, so that the air pressure inside the installation tube tends to normal again. At this time, the friction plate is attached to the middle side of the pressure block, and magnetization is applied to the pressure block, so that the pressure block adsorbs the friction plate, that is, the pressure relief rod is limited by the pressure block to ensure that the air pressure inside and outside the installation tube is the same. When the pressing is completed, the hydraulic cylinder is driven in the reverse direction to move the pressing mechanism upward as a whole. At this time, the air pressure inside and outside the installation tube is the same and loses the negative pressure state, that is, the adsorption effect on the upper plate is eliminated. After the pressing mechanism moves upward for a distance, the pressure block is demagnetized, prompting the pressure block to reset under the elastic state, and the pressure relief rod will also reset at the same time, and the staff can remove the pressed display screen in the pressing frame.

[0016] Preferably, a mounting plate is fixedly connected to the outer surface of the mounting frame, wherein the interior of the mounting plate is set to be hollow, and the internal cavity of the mounting plate is communicated with the internal cavity of the collar, a sealing plate is buckled and fixedly connected to the bottom of the mounting plate, and through holes are reserved through the edges of the sealing plate, and a second elastic telescopic rod is fixedly connected to the bottom surface of the sealing plate, wherein the second elastic telescopic rod is communicated with the through hole on the sealing plate, and a pressing plate is fixedly connected to the output end of the second elastic telescopic rod, wherein a plurality of pressing plates are provided, and the pressing plates are arranged in contact with each other. When the upper plate and the lower plate are pressed together by the pressing mechanism, the extrusion rod will move into the ring under the action of pressure, thereby increasing the air pressure in the ring. When the air pressure in the ring increases, the air pressure will be transmitted to the internal cavity of the mounting plate, that is, the air pressure inside the mounting plate will also increase during the pressing process, that is, the air pressure inside the mounting plate will be released through the second elastic telescopic rod, that is, the second elastic telescopic rod will apply a pressing force to the pressing plate under the action of air pressure, thereby causing the pressing plate to move downward and finally fit onto the surface of the upper plate and be pressed and pressed together.

[0017] A processing technology of an alignment and pressing device for processing a naked-eye 3D display screen specifically comprises the following steps:

[0018] S1, placing the upper plate of the display screen on the preset frame according to the size, and placing the lower plate of the display screen on the pressing frame according to the size;

[0019] S2, drive the mounting frame to move to the top of the preset frame by starting the motor and the hydraulic cylinder, then adjust the position of the mounting tube by rotating the handle so that its covering surface fits the edge of the upper plate of the display screen and continue to drive the hydraulic cylinder to move downward so that the rubber ring fits the surface of the upper plate;

[0020] S3. After the rubber ring is attached to the surface of the upper plate, the hydraulic cylinder is continuously driven to make the mounting frame drop slightly downward, and then the hydraulic cylinder is driven in the reverse direction to make the mounting frame move upward, and the upper plate of the display screen is automatically adsorbed, so that the upper plate of the display screen is separated from the preset frame;

[0021] S4, reverse drive the motor to move the mounting frame to the top of the pressing frame, and start the hydraulic cylinder to lower the mounting frame, so that the upper plate and the lower plate of the display screen are fitted together. At this time, continue to drive the hydraulic cylinder to lower the mounting frame to squeeze and press the upper plate and the lower plate through the rubber ring and the pressing plate, so that the upper plate and the lower plate are kept under a fixed squeezing force for a period of time, and then reverse drive the hydraulic cylinder to force the mounting frame to move up. During this process, the rubber ring is separated from the adsorption of the upper plate of the display screen;

[0022] S5, taking out the pressed display screen in the pressing frame to complete the pressing process of the display screen.

[0023] The present invention provides a positioning and pressing device for processing a naked-eye 3D display screen and a processing technology thereof. It has the following beneficial effects:

[0024] 1. The alignment and pressing equipment for processing naked-eye 3D display screens can adjust the coverage of the pressing mechanism according to the size of the display screen, and achieve the effect of adapting to the pressing of multiple-size display screens by setting the preset frame and the pressing frame in a stepped shape. The moving distance of the pressing mechanism is fixed by controlling the synchronous movement of the pressing mechanism, thereby ensuring that the pressing mechanism can always fix and adsorb the edge of the display screen, greatly improving the pressing effect of the device.

[0025] 2. The alignment and pressing equipment for processing the naked-eye 3D display screen can realize adsorption of the upper plate by the pressing mechanism under a relatively small extrusion pressure by setting a pressing mechanism. At the same time, the adsorption of the upper plate can be automatically released by the pressing force during the pressing process, thereby realizing the transportation and pressing of the upper plate as one, and realizing it automatically throughout the whole process, which greatly improves the production efficiency. At the same time, it cooperates with the positioning mechanism to complete the pressing of various screens, which not only saves a lot of manpower and material resources, but also improves the pressing accuracy.

[0026] 3. The alignment and pressing equipment for processing the naked-eye 3D display screen realizes automatic balance of the air pressure inside the installation plate by setting multiple pressing plates and cooperating with the stepped edge of the pressing frame, and at the same time provides good extrusion force for the upper plate, which greatly improves the pressing effect of the upper plate and the lower plate, and greatly improves the pressing effect of the display screen by increasing the coverage area.

[0041] The pressing mechanism 6 is fixedly mounted at the lower end of the positioning mechanism 5 and is also arranged above the pressing frame 4. The pressing mechanism 6 is used to cooperate with the positioning mechanism 5 to align and press the display screen;

[0042] The positioning mechanism 5 includes a connecting plate 51, which is fixedly connected to the top of the support frame 2. The connecting plate 51 is provided with two pieces, and a driving rod 52 is rotatably connected between the two connecting plates 51. The driving rod 52 is set as a threaded rod. The output end of the driving rod 52 is rotatably connected to the motor 53. Matching rods 54 are set on both sides of the driving rod 52. The motor 53 is fixedly installed on the outer surface of the connecting plate 51. The matching rod 54 and the driving rod 52 are set in the same horizontal plane. Both ends of the matching rod 54 are fixedly connected to the inner surface of the connecting plate 51. The outer surface of the driving rod 52 is threadedly connected to a moving plate 55, and the moving plate 55 is also slidably connected to the outer surface of the matching rod 54.

[0043] A hydraulic cylinder 56 is fixedly connected to the bottom surface of the movable plate 55, and a pushing block 57 is fixedly connected to the output end of the hydraulic cylinder 56. A connecting rod 58 is fixedly inserted at the bottom of the pushing block 57, and a mounting frame 59 is fixedly connected to the end of the connecting rod 58 away from the pushing block 57. The mounting frame 59 is arranged in a cross shape, and sliding grooves 510 are symmetrically provided on the upper surface of the mounting frame 59, wherein four sliding grooves 510 are arranged, and the pressing mechanism 6 is slidably connected in the sliding grooves 510 through a spring.

[0044] The outer surface of the connecting rod 58 is slidably sleeved with a first sleeve 511, the outer surface of the first sleeve 511 is rotatably connected with a transmission belt 512, the end of the transmission belt 512 away from the first sleeve 511 is rotatably connected to the second sleeve 513, the bottom of the second sleeve 513 is rotatably connected to an extension plate 514, the end of the extension plate 514 away from the second sleeve 513 is fixedly connected to the side of the mounting frame 59, and the top of the second sleeve 513 is fixedly connected to a rotating handle 515.

[0045] The bottom end of the first sleeve 511 is fixedly connected to a stabilizing frame 517, wherein the stabilizing frame 517 is arranged in a cross shape, and the outer end of the stabilizing frame 517 is fixedly connected to a driving frame 518, wherein the driving frame 518 is arranged in a four-pointed star shape, and the outer end of the driving frame 518 is slidably connected to the top outer surface of the pressing mechanism 6, and the driving frame 518 is also rotatably sleeved on the bottom outer surface of the connecting rod 58.

[0046] During operation, when the display screen needs to be pressed, the upper plate can be placed in the preset frame 3, and the lower plate can be placed in the pressing frame 4, and the motor 53 can be started at the same time. The driving rod 52 is driven to rotate by the motor 53, that is, the movable plate 55 is driven to move above the preset frame 3 on the driving rod 52 and the matching rod 54. When the movable plate 55 moves to the top of the preset frame 3, the hydraulic cylinder 56 is driven. Under the drive of the hydraulic cylinder 56, the pushing block 57 starts to move downward and close to the preset frame 3, that is, the positioning mechanism 5 and the pressing mechanism 6 under the pushing block 57 are close to the preset frame 3. When the positioning mechanism 5 and the pressing mechanism 6 are located above the preset frame 3, the first sleeve 511 can be caused to start rotating by rotating the rotating handle 515, which means that the mounting frame 59 starts to rotate. When the mounting frame 59 starts to rotate, the pressing mechanism 6 will be driven to move relatively close to the mounting frame 59, thereby reducing and expanding the coverage range of the pressing mechanism 6. The pressing mechanism 6 is arranged to cover a range of the display screen so as to adjust the coverage range of the pressing mechanism 6 according to the size of the display screen, and the preset frame 3 and the pressing frame 4 are set to be stepped to achieve the effect of adapting to the pressing of display screens of multiple sizes, and the synchronous movement of the pressing mechanism 6 is controlled to make the moving distance of the pressing mechanism 6 fixed, so as to ensure that the pressing mechanism 6 can always fix and adsorb the edge of the display screen, which greatly improves the pressing effect of the device. When the size adjustment is completed, the hydraulic cylinder 56 is continued to be driven to cause the pressing mechanism 6 to move downward and adsorb the upper plate. When the upper plate is adsorbed, the hydraulic cylinder 56 is driven in the reverse direction to cause the upper plate to leave the preset frame 3, and the motor 53 is started in the reverse direction at the same time to drive the moving plate 55 to approach the pressing frame 4. When the moving plate 55 moves to the top of the pressing frame 4, the hydraulic cylinder 56 is driven again to cause the pressing mechanism 6 to move downward and finally affix the upper plate to the upper surface of the lower plate, and the pressing of the display screen is realized by the pressing.

[0047] Second embodiment: Figures 2 to 10 As shown, the pressing mechanism 6 includes a sliding rod 61, the top end of the sliding rod 61 is slidably connected in the sliding groove 510 through a spring, the bottom outer surface of the sliding rod 61 is slidably connected with a ring 62, the bottom inner surface of the ring 62 is slidably connected with an extrusion rod 63, the bottom of the extrusion rod 63 is fixedly connected with a mounting tube 64, the bottom inner surface of the mounting tube 64 is slidably connected with an extrusion column 65, and the bottom of the extrusion column 65 is fixedly connected with a rubber ring 66.

[0048] A through hole is reserved on the upper surface of the extrusion column 65, and a first elastic telescopic rod 67 is fixedly connected to the edge of the upper surface of the extrusion column 65. A positioning ring 68 is fixedly connected to the top of the first elastic telescopic rod 67. The positioning ring 68 is fixedly connected to the inner surface of the mounting tube 64. A support ring 69 is arranged above the positioning ring 68. The support ring 69 is fixedly connected to the inner surface of the top end of the mounting tube 64, wherein six support rings 69 are arranged around the central axis at fixed intervals, and a pressure relief rod 610 is slidably sleeved on the support ring 69 through a spring, and one end of the pressure relief rod 610 away from the support ring 69 is slidably penetrated and connected to the outer surface of the top end of the mounting tube 64, and a connecting groove 611 is opened on the outer surface of the pressure relief rod 610, wherein the connecting groove 611 is initially located in the mounting tube 64 under the action of elastic force.

[0049] A friction plate 612 is fixedly connected to the inner surface of the pressure relief rod 610. Six friction plates 612 are arranged, and the six friction plates 612 are combined into a circular ring shape. A pressure block 613 is fixedly connected to the middle of the upper surface of the extrusion column 65. The top side surface of the pressure block 613 is arranged in an arc shape. An electromagnet is arranged on the pressure block 613, and the outer surface of the pressure block 613 is arranged to be smooth.

[0050] The interior of the rubber ring 66 is hollow, and an elastic ring 614 is symmetrically fixedly connected to the inner surface of the rubber ring 66. The cross section of the elastic ring 614 is arc-shaped, and air holes 615 are opened on the surface of the elastic ring 614 at fixed intervals around the central axis. The air holes 615 also penetrate the rubber ring 66.

[0051] When working, when the pressing mechanism 6 is close to the upper plate, the rubber ring 66 at its lower end will first contact the upper plate. When the rubber ring 66 is close to the upper plate, the hydraulic cylinder 56 will drive the extrusion column 65 to move into the mounting tube 64 under the action of pressure, thereby increasing the air pressure inside the mounting tube 64. When the air pressure increases to a certain extent, the pressure relief rod 610 will be driven to move outward in the mounting tube 64, and then the mounting tube 64 will be connected inside and outside through the connecting groove 611 on the pressure relief rod 610, so that the air pressure inside the mounting tube 64 drops to a normal level. When the hydraulic cylinder 56 is driven in the reverse direction, the extrusion column 65 will move to the mounting tube 64 under the elastic force of the first elastic telescopic rod 67. The upper plate 613 on the upper plate 614 is moved upwards and gradually contacts the friction plate 612 by setting the upper end side of the pressure block 613 to be inclined. The pressure relief rod 610 is pushed to gradually move outside the installation tube 64, thereby connecting the inside and outside of the installation tube 64 again, so that the air pressure inside the installation tube 64 returns to normal again. At this time, the friction plate 612 is attached to the middle side of the pressure block 613, and the pressure block 613 is magnetized, so that the pressure block 613 adsorbs the friction plate 612, that is, the pressure relief rod 610 is limited by the pressure block 613 to ensure that the air pressure inside and outside the installation tube 64 is the same. When the pressing is completed, the hydraulic cylinder 56 is driven in the reverse direction to move the pressing mechanism 6 upward as a whole. At this time, the air pressure inside and outside the installation tube 64 is the same and the negative pressure state is lost, that is, the adsorption effect on the upper plate is eliminated. When the pressing mechanism 6 moves upward for a distance After separation, the pressure block 613 is demagnetized to reset the pressure block 613 under the elastic state, and the pressure relief rod 610 is also reset. The staff can remove the pressed display screen in the pressing frame 4. By setting the pressing mechanism 6, the upper plate can be adsorbed by the pressing mechanism 6 under a smaller extrusion pressure. At the same time, the adsorption of the upper plate can be automatically released by the pressing force during the pressing process, thereby realizing the transportation and pressing of the upper plate as one, and the whole process is automatically realized, which greatly improves the production efficiency. At the same time, the positioning mechanism 5 is cooperated to complete the pressing of various screens, which not only saves a lot of manpower and material resources, but also improves the pressing accuracy.

[0052] The third embodiment: Figures 1 to 5As shown, the outer surface of the mounting frame 59 is fixedly connected to a mounting plate 616, wherein the interior of the mounting plate 616 is set to be hollow, and the internal cavity of the mounting plate 616 is connected to the internal cavity of the ring 62, and the bottom of the mounting plate 616 is buckled and fixedly connected to a sealing plate 617, and the edges of the sealing plate 617 are penetrated with reserved through holes, and the bottom surface of the sealing plate 617 is fixedly connected to a second elastic telescopic rod 618, wherein the second elastic telescopic rod 618 is connected to the through hole on the sealing plate 617, and the output end of the second elastic telescopic rod 618 is fixedly connected to a pressing plate 619, wherein a plurality of pressing plates 619 are provided, and the pressing plates 619 are arranged in contact with each other.

[0053] During operation, when the upper plate and the lower plate are pressed together by the pressing mechanism 6, the extrusion rod 63 will move into the ring 62 under the action of pressure, thereby increasing the air pressure in the ring 62. When the air pressure in the ring 62 increases, the air pressure will be transported into the internal cavity of the mounting plate 616, that is, the air pressure inside the mounting plate 616 will also increase during the pressing process, that is, the air pressure inside the mounting plate 616 will be released through the second elastic telescopic rod 618, that is, the second elastic telescopic rod 618 applies an extrusion force to the pressing plate 619 under the action of air pressure, thereby causing the pressing plate 619 to move downward and finally fit onto the surface of the upper plate, and be pressed and pressed together. By providing a plurality of pressing plates 619 and cooperating with the stepped edge of the pressing frame 4, the air pressure inside the mounting plate 616 is automatically balanced, and at the same time, a good extrusion force is provided for the upper plate, thereby greatly improving the pressing effect on the upper and lower plates, and greatly improving the pressing effect on the display screen by increasing the coverage area.

[0057] S3, after the rubber ring 66 is attached to the surface of the upper plate, the hydraulic cylinder 56 is continuously driven to make the mounting frame 59 descend slightly, and then the hydraulic cylinder 56 is reversely driven to make the mounting frame 59 move upward, and the upper plate of the display screen is automatically adsorbed, so that the upper plate of the display screen is separated from the preset frame 3;

[0058] S4, reverse drive motor 53 to move mounting frame 59 to the top of pressing frame 4, and start hydraulic cylinder 56 to make mounting frame 59 descend, so that the upper plate and the lower plate of the display screen are fitted together. At this time, continue to drive hydraulic cylinder 56 to make mounting frame 59 descend, and squeeze and press the upper plate and the lower plate through rubber ring 66 and pressing plate 619, so that the upper plate and the lower plate are kept under fixed squeezing force for a period of time, and then reverse drive hydraulic cylinder 56 to force mounting frame 59 to move up, and in this process, rubber ring 66 is separated from adsorption to the upper plate of the display screen;
