Description

A detection device for all-in-one computer monitors Technical Field

[0001] This invention relates to the field of display testing technology, specifically to a testing device for all-in-one computer displays. Background Technology

[0002] In the manufacturing process of all-in-one computers and standalone monitors, the quality inspection of their displays is a key step in ensuring the quality of the final product. Defects such as bright spots, dark spots, dead pixels, color uniformity, and light leakage of the monitor need to be identified through specialized testing equipment. At present, the industry generally adopts a combination of manual inspection and automated inspection, but there are still many technical bottlenecks that need to be solved in practical applications.

[0003] Existing testing processes typically divide monitor positioning and clamping, screen cleaning, and image acquisition into multiple independent steps. Operators need to clean the screen first, then fix the monitor at the testing station, and finally start the camera to take pictures. This segmented operation not only prolongs the single testing cycle, but also makes it difficult to improve overall efficiency due to excessive manual intervention, which cannot meet the high-speed requirements of modern production lines. Therefore, a testing device for all-in-one computer monitors is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detection device for a computer all-in-one monitor, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a testing device for a computer all-in-one monitor, including a workbench, and further including: a base, disposed at the bottom of the workbench for supporting the workbench; multiple brackets, installed above the workbench to form a frame structure and form a testing cavity; multiple baffles, installed on the frame of the brackets, and a camera is installed on the brackets for taking pictures of the monitor; a front baffle, installed on the front of the base; a clamping mechanism, disposed above the workbench for clamping the monitor; and a cleaning mechanism, disposed above the workbench for cleaning foreign objects from the monitor; wherein, the clamping mechanism includes: a fixing plate, fixedly connected to the rear top of the workbench; two rails, fixedly connected to the top sides of the workbench; and a clamping plate, disposed above the two rails, and clamping the monitor in cooperation with a clamping component disposed in front of the clamping plate.

[0006] Preferably, the clamping mechanism further includes: two fixing blocks fixedly connected to the top two sides of the worktable; two limiting rods respectively disposed on the top two sides of the worktable and fixedly connected to the fixing blocks and the fixing plate; the clamping plate 1 slides above the two tracks, and the two ends of the clamping plate 1 slide on the outer walls of the two limiting rods respectively.

[0007] Preferably, each of the limiting rods is fitted with a spring on its outer wall and positioned between the fixing plate and the clamping plate to push the clamping plate forward.

[0008] Preferably, the clamping assembly includes: a cylinder, fixedly connected to the bottom of the worktable; a second clamping plate, slidably connected to two rails, and a through hole provided on the worktable; and a slider, fixedly connected below the second clamping plate and sliding within the through hole, wherein the output end of the cylinder is connected to the slider for pushing the slider to move.

[0009] Preferably, the clamping assembly further includes: a movable block, disposed above the second clamping plate, and connected to the second clamping plate by two adjusting screws; the bottom of the movable block and the top of the second clamping plate are provided with staggered grooves, and the movable block and the second clamping plate slide alternately through the grooves; a placement plate, fixedly connected to the back of the second clamping plate, sliding above the track, and extending rearward through the first clamping plate for placing the display.

[0010] Preferably, the cleaning mechanism includes: two slides disposed above the workbench and sliding on a support; and a brush cylinder rotatably connected to the two slides via a drive shaft for cleaning the display screen.

[0011] Preferably, the cleaning mechanism further includes: two connecting plates, fixedly connected to the frame and mounted on the bracket; two connecting rods, located on both sides of the worktable and respectively connected to the connecting plates and the limiting rods; and two springs, respectively sleeved on the outer walls of the two connecting rods, for pushing the slide table to move the brush cylinder downward and fit against the display screen.

[0012] Preferably, two racks are fixedly connected to both sides of the movable block, and a T-groove is formed at the bottom of the rack; a T-shaped slider is slidably connected to the inner wall of the T-groove; sliding grooves are formed on both sides of the placement plate, and a spherical rod is slidably connected in the sliding groove, with a connecting block fixedly connected to the end of the spherical rod away from the sliding groove; two sliding columns are fixedly connected to the top of the connecting block, and the T-shaped slider slides on the outer wall of the sliding column to support the rack; the rack is wedge-shaped and meshes with a gear, driving the gear to rotate the brush cylinder when moving.

[0013] The present invention adopts the above technical solution and can bring the following beneficial effects: 1. The testing device for computer all-in-one monitors links the clamping action and the cleaning function through a gear and rack mechanism. When the cylinder drives the clamping plate assembly to move and clamp the monitor, the meshing of the rack and gear automatically drives the brush cylinder to rotate and clean the screen. By realizing the simultaneous cleaning during the clamping operation, the positioning, fixing and cleaning processes that originally needed to be carried out in steps are integrated into a continuous automated process, which greatly shortens the cycle time of a single test and significantly improves the testing efficiency of monitors on the production line.

[0014] 2. This testing device for all-in-one computer monitors features an alternating groove design between the movable block and the clamping plate, along with an adjustable screw. This allows the device to adapt to monitors of different thicknesses. Spring 1 continuously provides a stable preload, ensuring the monitor remains firmly fixed during testing and effectively preventing image blurring caused by vibration. This adaptive design allows the same device to be used for testing monitors of various specifications, greatly enhancing the versatility and practicality of the equipment.

[0015] 3. This testing device for all-in-one computer monitors, through its cleaning mechanism, ensures that the brush cylinder maintains appropriate pressure against the screen surface under the action of spring two. Combined with the stable rotation brought by the rack and pinion drive, it achieves comprehensive and thorough screen cleaning without blind spots. This mechanism of cleaning immediately before testing effectively removes interfering factors such as dust and fingerprints, providing a clean screen condition for subsequent image acquisition. With a stable clamp, the camera can acquire high-definition, shake-free monitor images, providing a reliable image basis for defect identification and significantly improving the detection accuracy of defects such as bright spots, dark spots, and dead pixels.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figures 1-6. One embodiment of the present invention is: a testing device for a computer all-in-one monitor, including a workbench 1, and further including: a base 2, disposed at the bottom of the workbench 1 for supporting the workbench 1; multiple brackets 3, installed above the workbench 1 to form a frame structure and form a testing cavity; multiple baffles 4, installed on the frame of the brackets 3, and a camera is installed on the brackets 3 for taking pictures of the monitor; a front baffle 5, installed on the front of the base 2; a clamping mechanism 6, disposed above the workbench 1 for clamping the monitor; and a cleaning mechanism 7, disposed above the workbench 1 for cleaning foreign objects from the monitor; wherein, the clamping mechanism 6 includes: a fixing plate 61, fixedly connected to the rear top of the workbench 1; two rails 62, fixedly connected to the top sides of the workbench 1; and a clamping plate 63, disposed above the two rails 62, and clamping the monitor in cooperation with a clamping component 67 disposed in front of the clamping plate 63.

[0020] The clamping mechanism 6 also includes: two fixed blocks 64, which are fixedly connected to the top two sides of the worktable 1; two limiting rods 65, which are respectively set on the top two sides of the worktable 1 and fixedly connected to the fixed blocks 64 and the fixed plate 61; and a clamping plate 63 that slides above the two rails 62, with the two ends of the clamping plate 63 sliding on the outer walls of the two limiting rods 65 respectively.

[0021] Each limiting rod 65 is fitted with a spring 66 on its outer wall and is positioned between the fixing plate 61 and the clamping plate 63 to push the clamping plate 63 forward.

[0022] The clamping assembly 67 includes: a cylinder 671, which is fixedly connected to the bottom of the worktable 1; a clamping plate 673, which is slidably connected to two rails 62, and the worktable 1 has a through hole; and a slider 672, which is fixedly connected to the lower part of the clamping plate 673 and slides within the through hole. The output end of the cylinder 671 is connected to the slider 672 and is used to push the slider 672 to move.

[0023] The clamping assembly 67 further includes: a movable block 674, which is disposed above the second clamping plate 673 and connected to the second clamping plate 673 by two adjusting screws 675; the bottom of the movable block 674 and the top of the second clamping plate 673 are provided with staggered grooves, and the movable block 674 and the second clamping plate 673 slide alternately through the grooves; and a placement plate 676, which is fixedly connected to the back of the second clamping plate 673, slides above the track 62, and extends rearward through the first clamping plate 63 for placing a display.

[0024] The cleaning mechanism 7 includes: two slides 73, which are located above the workbench 1 and slide on the support 3; and a brush cylinder 75, which is rotatably connected to the two slides 73 via a drive shaft for cleaning the monitor screen.

[0025] The cleaning mechanism 7 also includes: two connecting plates 71, which are fixedly connected to the frame and installed on the bracket 3; two connecting rods 72, which are set on both sides of the worktable 1 and connected to the connecting plates 71 and the limiting rods 65 respectively; and two springs 74, which are respectively sleeved on the outer walls of the two connecting rods 72, for pushing the slide table 73 to drive the brush cylinder 75 to move down and fit against the display screen.

[0026] Two racks 77 are fixedly connected to both sides of the movable block 674, and a T-groove is provided at the bottom of the rack 77; a T-slider 710 is slidably connected to the inner wall of the T-groove; sliding grooves are provided on both sides of the placement plate 676, and a ball rod 78 is slidably connected in the sliding groove, and a connecting block 79 is fixedly connected to the end of the ball rod 78 away from the sliding groove; two sliding columns 711 are fixedly connected to the top of the connecting block 79, and the T-slider 710 slides on the outer wall of the sliding column 711 to support the rack 77; the rack 77 is wedge-shaped, and the rack 77 meshes with the gear 76, driving the gear 76 to rotate the brush cylinder 75 when moving.

[0027] Working principle: When testing the monitor panel, the operator places the monitor to be tested on the placement plate 676 and aligns one side of the monitor with the clamping plate 673. Then, the cylinder 671 is activated, its output pushing the slider 672 and the clamping plate 673 along the track 62. This causes the entire clamping plate 673 and placement plate 676 to move backward. Depending on the size of the monitor, the placement plate 676 will pass under the clamping plate 63, causing the monitor to contact and be fixed against the clamping plate 673. Under the continuous pushing of the spring 66, Clamping plate 63 always has a forward tendency, thus providing a forward reference positioning force for the display, making it close to the positioning component in front. When the thickness of the display changes, by adjusting the two adjusting screws 675, the movable block 674 is driven to move up and down, thereby adapting to displays of different thicknesses and making the top of the movable block 674 lower than the height of the display, and clamping the display. It adapts to displays of different thicknesses and provides a uniform clamping force. Finally, the display is stably clamped between clamping plate 63 and clamping plate 673.

[0028] When the cylinder 671 drives the clamping plate 673 assembly to move backward to clamp the display, the racks 77 fixed on both sides of the movable block 674 move backward in sync.

[0029] The wedge-shaped rack 77 meshes with the gear 76 mounted on the rotating shaft of the brush cylinder 75. The horizontal backward movement of the rack 77 is converted into the rotational movement of the gear 76, thereby driving the brush cylinder 75 to rotate. When the rack 77 moves from the higher part of the wedge to the contact point, under the action of the second spring 74, the entire slide table 73 and the brush cylinder 75 mounted on it are pressed downward, ensuring that the bristles of the brush cylinder 75 are more tightly attached to the display screen. Thus, while the clamping action is completed, the rotating brush cylinder 75 also simultaneously completes the cleaning and dust removal of the screen surface, preparing for subsequent high-quality image acquisition. The rack 77 slides on the slide column 711 through the T-shaped slider 710. This structure provides stable vertical support for the rack 77, while allowing it to adaptively float with the up and down adjustment of the movable block 674 during the clamping process, ensuring the reliability of the transmission.

[0030] After cleaning and stabilizing the clamp, the industrial camera mounted on the bracket 3 frame begins to work. Since the screen has been cleaned and the monitor is firmly clamped without vibration, the camera can capture high-definition, shake-free monitor images. Inspectors or image processing software can then analyze the captured images to determine whether the monitor has defects such as bright spots, dark spots, dead pixels, color uniformity, and light leakage.

[0031] After the test is completed, cylinder 671 moves forward, pushing clamp 673 and movable block 674 forward. The forward movement of movable block 674 drives rack 77 forward, meshing with gear 76 again and rotating, causing brush cylinder 75 to rotate in the opposite direction for secondary cleaning and preparation for the next work. Meanwhile, the display is sent out of the cavity formed by baffle 4. At this time, the operator can easily remove the tested display from the placement plate 676.

[0032] This invention provides a testing device for an all-in-one computer monitor. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
