Description

Technical Field

[0001] This invention relates to the field of display screen manufacturing technology, specifically to a novel inspection device for processing flat panel displays. Background Technology

[0002] Inspection for new flat panel display processing is a core process in display panel manufacturing to ensure the yield and performance of the final product. Specifically, it refers to the automated detection and evaluation of quality indicators such as appearance defects, pixel illumination status, color uniformity, and signal response using optical, electrical, or machine vision technologies. This technology aims to screen out defective screens and prevent them from entering downstream assembly or the end market. Chinese patent application number 202411686210.0 discloses an LED display inspection device and its inspection method, relating to the field of digital television testing instruments. The device includes a frame, with a control box fixedly connected to the side wall of the frame, and a lead screw rotatably connected to the lower end of the frame. The other end of the rod is fixedly connected to the handle. A one-way bearing is rotatably connected to the inner wall of the frame. The outer ring of the one-way bearing is fixedly connected to the gear, and the inner ring of the one-way bearing is fixedly connected to the lead screw. A telescopic rod is fixedly connected to the bottom of the frame. A contact plate is fixedly connected to the top of the telescopic rod. A rack is fixedly connected to the side of the contact plate. The sliding plate drives the first electric push rod to move downward, so that the telescopic end of the first electric push rod presses against the top of the contact plate. The lead screw drives the limiting plate and the LED display detector to move a small distance on the X-axis. The LED display detector can move to the next detection area of ​​the display screen to realize automatic cyclic detection, ensuring that every area of ​​the display screen can be accurately detected and avoiding omissions. This technical solution only addresses the problem of the difficulty in operation caused by the need to constantly adjust the position of the LED display detector during testing. However, this solution requires fixing the display screen first and then controlling the detector to move in the Z and Y axes. This not only results in slow testing speed but also requires a significant amount of time to place and fix the display screen during the production process, leading to discontinuous production and low production efficiency. Furthermore, using an electric push rod to push the extrusion plate to press and fix the display screen can easily cause mechanical damage to the display screen due to external forces.

This allows the device to be adjusted according to the width of the display screen under inspection, so as to be suitable for display screens of different sizes.

[0024] In other aspects, this embodiment also provides a display screen conveying mechanism 5, such as...

There are two sets of follower shafts 510, with one end near the limiting plate 401 movably installed on both ends of the limiting plate 401. The follower shaft 510 is located below the conveyor belt 503. The end of the follower shaft 510 away from the limiting plate 401 is inserted into the transmission cylinder 507.

The first gear 512 and the second gear 513 are connected by meshing. The worm gear 506 is driven to rotate by the dual-axis motor 505. When the worm gear 506 rotates, it drives the transmission cylinder 507 to rotate through the worm wheel 509. Since the limiting strip 508 in the transmission cylinder 507 is inserted into the limiting groove 511 on the follower shaft 510, when the transmission cylinder 507 rotates, it drives the follower shaft 510 to rotate at the same time. When the follower shaft 510 rotates, it drives the first gear 512 to rotate, and drives the drive roller 502 to rotate through the second gear 513. The drive roller 502 drives the conveyor belt 503 to move the display screen on it.

The first bevel gear 617 is fixedly installed at the end of the horizontal shaft 616 located inside the connecting frame 606. By driving the follower cylinder 609 to descend and gradually insert into the synchronization cylinder 613, and gradually come into contact with the synchronization cylinder 613, the second spring 611 is compressed. After the synchronization plug 610 comes into contact with the synchronization cylinder 613, it drives the first vertical shaft 612 to rotate synchronously with the follower cylinder 609. The first vertical shaft 612 then drives the third gear 614 to rotate. At this time, through the meshing of the third gear 614 and the rack 615, the translation seat 302 is driven to move a certain distance on the translation track 301, so that the display screen moves forward a certain distance.

[0031] In this embodiment, as Figure 2 and Figure 8 As shown, the intermittent travel mechanism 6 includes a second vertical shaft 618, a synchronization groove 619, a synchronization rod 620, a second bevel gear 621, and a transmission belt 622. The second vertical shaft 618 is movably mounted on the top of the connecting frame 606 on the side away from the support plate 1. The second vertical shaft 618 is inserted into the follower cylinder 609. The synchronization groove 619 is opened in the middle of the follower cylinder 609. The synchronization rod 620 is fixedly mounted on the bottom end of the second vertical shaft 618 and inserted into the synchronization groove 619. The second bevel gear 621 is fixedly mounted on the second vertical shaft 618 and located below the first bevel gear 617. It is movably connected to the first bevel gear 617 through meshing. There are two transmission belts 622. The top ends are movably sleeved on both ends of the translation screw 202, and the bottom ends are movably sleeved on the ends of the horizontal shafts 616 on the two support plates 1 away from the second vertical shaft 618. The transmission belt 622 drives the horizontal shaft 616 to rotate, causing the first bevel gear 617 to rotate with the horizontal shaft 616. The second bevel gear 621 drives the second vertical shaft 618 to rotate. When the second vertical shaft 618 rotates, the synchronizing rod 620 is inserted into the synchronizing groove 619, so that the follower cylinder 609 continues to rotate synchronously with the second vertical shaft 618 during the descent.

[0032] Working principle: In use, this invention utilizes a conveying mechanism in a novel flat panel display processing production line to transport the display screen onto two conveyor belts 503. A dual-axis motor 505 is started, driving a worm gear 506 to rotate. When the worm gear 506 rotates, it drives a transmission cylinder 507 to rotate via a worm wheel 509. Since the limiting strip 508 inside the transmission cylinder 507 is inserted into the limiting groove 511 on the follower shaft 510, the rotation of the transmission cylinder 507 simultaneously drives the follower shaft 510 to rotate. When the follower shaft 510 rotates, it drives the first gear 512 to rotate, which in turn drives the drive roller 502 to rotate via the second gear 513. The drive roller 502 then drives the conveyor belt 503, moving the display screen on it, allowing the display screen to be placed stably after being moved horizontally. After the display screen is placed, in order to prevent the display screen from shifting and affecting the inspection of the display screen, the bottom end of the negative pressure tube 305 is connected to an external negative pressure generator, so that the suction cup 306 can be attached to the bottom end of the display screen to fix the display screen. Once the display screen is stably positioned, the inspection can begin. At this point, the translation motor 208 is activated, driving the translation screw 202 to rotate. The translation screw 202 then drives the translation block 204 to move within the translation groove 201 towards the end furthest from the translation motor 208. The translation block 204 then moves the display screen inspection instrument 206 above the display screen to inspect it. Once the display screen inspection instrument 206 has moved beyond the side of the display screen, the translation block 204 continues to move, moving further away from the display screen. A set of trapezoidal blocks 602 at one end of the translation motor 208 is pressed down, causing the trapezoidal blocks 602 to move downward from the telescopic groove 601. When the trapezoidal blocks 602 move downward, the lifting plate 607 moves downward at the same time through the lifting rod 604. At this time, the first spring 605 is compressed. When the lifting plate 607 descends, it drives the lifting cylinder 608 to descend at the same time, so that the follower cylinder 609 descends synchronously with the lifting cylinder 608. The follower cylinder 609 descends and gradually inserts into the synchronous cylinder 613, and gradually comes into contact with the synchronous cylinder 613. At this time, the second spring 611 is compressed. When the translation screw 202 rotates, it drives the horizontal shaft 616 to rotate through the transmission belt 622, causing the first bevel gear 617 to rotate with the horizontal shaft 616, and drives the second vertical shaft 618 to rotate through the second bevel gear 621. When the second vertical shaft 618 rotates, the synchronizing rod 620 is inserted into the synchronizing groove 619, so that the follower cylinder 609 still rotates synchronously with the second vertical shaft 618 during the descent. After the synchronizing plug 610 and the synchronizing cylinder 613 are in contact, the first vertical shaft 612 is driven to rotate synchronously with the follower cylinder 609. The first vertical shaft 612 then drives the third gear 614 to rotate. At this time, through the meshing of the third gear 614 and the rack 615, the translation seat 302 is driven to move a certain distance on the translation track 301, so that the display screen moves forward a certain distance. Then, the translation block 204 is driven to move closer to the translation motor 208, so that the display screen inspection instrument 206 can inspect the area of ​​the display screen that has just moved forward on the return trip. After the display screen moves a certain distance, the drive translation block 204 returns. At this time, the trapezoidal block 602 is reset by the elastic force of the first spring 605 and the second spring 611, and the follower cylinder 609 rises and resets, so that the synchronizing plug 610 leaves the synchronizing cylinder 613. At this time, the third gear 614 stops rotating, so that the display screen stops moving. When the translation block 204 moves to one end close to the translation motor 208, it drives the third gear 614 on the other support plate 1 to rotate as it continues to move, so that the display screen moves forward a bit more. After the display screen inspection instrument 206 moves back and forth at a constant speed, it can inspect the two areas that have moved forward on the display screen. This cycle is repeated to perform a comprehensive inspection of the display screen. After the display screen has been fully inspected, the conveyor belt 503 is driven to rotate, so that the entire display screen is moved to the discharge conveyor mechanism on the production line, so that the inspection of the display screen can be carried out continuously on the production line. After the display screen leaves the conveyor belt 503, simply drive the translation block 204 away from the trapezoidal block 602, and then directly move the translation seat 302 to reset it, so that the next display screen can be received and inspected. Before inspection, the two-way threaded rod 402 can be rotated by turning the handle 404, so that the two limiting plates 401 can move simultaneously toward the middle of the connecting plate 304 or move in the opposite direction to adjust the distance between the two limiting plates 401. This allows the device to be adjusted according to the width of the display screen under inspection, so as to be suitable for display screens of different sizes.
