Description

Technical Field

[0001] This utility model relates to the field of wall panel inspection technology, and specifically discloses a wall panel surface defect detection device. Background Technology

[0002] Wall panels, as an important component of modern architectural decoration and partition systems, are widely used in interior and exterior decoration, partition walls, ceilings, and other fields. Their surface quality directly affects the final aesthetic effect and overall quality of the building. Therefore, inspecting the wall panel surface for defects (such as scratches, dents, color differences, stains, etc.) is a crucial step in the production process.

[0003] Currently, the industry generally adopts automated inspection technology with machine vision as its core. This technology uses industrial cameras to collect image data of the wall panel surface and transmits it to a computer. Based on image processing algorithms or artificial intelligence models, the images are intelligently analyzed to achieve automatic determination of product qualification.

[0004] However, existing detection devices typically have two problems: First, when a defective product is detected, the device can only record internal system data and cannot automatically mark it on the wall panel. Subsequently, it is still necessary to manually search for the defective product from the production line based on the alarm information and manually mark it. This process is inefficient and prone to errors. Second, industrial cameras used for image acquisition are usually directly fixed to the support base with several bolts. This installation method makes the disassembly and assembly process very cumbersome, and the operation is very troublesome when the camera needs to be maintained.

[0005] Therefore, a wall panel surface defect detection device is needed to solve the above problems. Utility Model Content

[0006] This utility model proposes a wall panel surface defect detection device that can automatically mark unqualified products. It is highly practical and easy to operate. At the same time, it facilitates the disassembly and maintenance of industrial cameras, improving convenience.

[0007] This utility model is implemented as follows: a wall panel surface defect detection device includes a base plate, a wall panel and an industrial camera. A support plate is provided above the base plate, and a support frame is fixedly connected through the upper end of the support plate. A marking mechanism is provided below the wall panel, and a limit mechanism is provided on the outside of the industrial camera.

[0008] The marking mechanism includes a horizontal tube fixedly connected inside the support frame. Multiple micro nozzles are connected to the outer wall of the horizontal tube. An ink storage tank is provided above the base plate. An ink delivery pump is provided outside the ink storage tank. The inlet of the ink delivery pump is connected to an ink extraction tube extending into the ink storage tank. A bend is connected between the outlet of the ink delivery pump and the horizontal tube. A controller is provided outside the ink delivery pump.

[0009] The limiting mechanism includes limiting blocks fixedly connected to the left and right sides of the industrial camera, a mounting base is provided above the wall panel, the lower end of the mounting base has a mounting groove, a lead screw is rotatably connected inside the mounting groove, a movable frame is threaded to the outer wall of the lead screw, a fixed frame is fixedly connected to the lower end of the mounting base, and limiting grooves are provided on the opposite sides of the movable frame and the fixed frame. The two limiting blocks are respectively inserted into the two limiting grooves. The limiting mechanism also includes a driving mechanism.

[0010] As a preferred embodiment of the wall panel surface defect detection device of this utility model, the driving mechanism includes a driving frame fixedly connected to the outer wall of the mounting base, a worm gear rotatably connected inside the driving frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the lead screw, and a handwheel extending to the outside of the driving frame fixedly connected to the upper end of the worm gear.

[0011] As a preferred embodiment of the wall panel surface defect detection device of this utility model, the upper end of the support frame is fixedly connected to a positioning frame located outside the wall panel.

[0012] As a preferred embodiment of the wall panel surface defect detection device of this utility model, a slide rail is installed inside the mounting groove, and the movable frame is slidably connected to the outer wall of the slide rail.

[0013] As a preferred embodiment of the wall panel surface defect detection device of this utility model, the upper end of the ink storage tank is fixedly connected to a feeding port, the outer wall of the feeding port is threadedly connected to a threaded cover, the upper end of the threaded cover is provided with an installation port, and a ventilation mesh plate is fixedly connected inside the installation port.

[0014] As a preferred embodiment of the wall panel surface defect detection device of this utility model, two first fixing plates are fixedly connected between the base plate and the support plate, the ink delivery pump is installed on the outer wall of the right first fixing plate, two second fixing plates are fixedly connected between the support plate and the mounting base, the controller is installed on the outer wall of the right second fixing plate, and multiple support columns are fixedly connected between the base plate and the ink storage tank.

[0015] As a preferred embodiment of the wall panel surface defect detection device of this utility model, the outer wall of the ink storage tank is connected to an ink discharge pipe with a manual valve.

[0016] The beneficial effects of this utility model are:

[0017] 1. This device uses an industrial camera to capture images of the wall panel surface and transmits them to a computer system for analysis. When a defect is detected, the control system immediately triggers the ink delivery pump to pump ink from the ink tank through the ink extraction tube and the bend tube into the horizontal tube. Finally, the ink is precisely sprayed onto the surface of the defective wall panel through a micro-nozzle on the horizontal tube, achieving automatic marking. This process requires no manual intervention, is highly practical and easy to operate, and significantly improves sorting efficiency and accuracy.

[0018] 2. The industrial camera's assembly and disassembly are achieved through a drive mechanism. This mechanism rotates a lead screw, causing the moving frame to move smoothly along the slide rail. Two limiting slots and two limiting blocks engage to limit movement, and disengaging the limiting blocks from the limiting slots releases the camera's restriction, allowing for quick installation and removal. This design eliminates the cumbersome process of using tools, greatly simplifying camera maintenance. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A wall panel surface defect detection device includes a base plate 1, a wall panel 5 and an industrial camera 18. A support plate 2 is provided above the base plate 1, and a support frame 3 is fixedly connected through the upper end of the support plate 2. A marking mechanism is provided below the wall panel 5, and a limit mechanism is provided on the outside of the industrial camera 18.

[0028] The marking mechanism includes a horizontal tube 6 fixedly connected inside the support frame 3. Multiple micro nozzles are connected to the outer wall of the horizontal tube 6. An ink storage tank 8 is provided above the base plate 1. An ink delivery pump 9 is provided outside the ink storage tank 8. The inlet of the ink delivery pump 9 is connected to an ink extraction tube 10 extending into the ink storage tank 8. A bend tube 11 is connected between the outlet of the ink delivery pump 9 and the horizontal tube 6. A controller 16 is provided outside the ink delivery pump 9.

[0029] The limiting mechanism includes limiting blocks 19 fixedly connected to the left and right sides of the industrial camera 18, a mounting base 17 is provided above the wall panel 5, the lower end of the mounting base 17 is provided with a mounting groove 20, a lead screw 21 is rotatably connected inside the mounting groove 20, a movable frame 22 is threadedly connected to the outer wall of the lead screw 21, a fixed frame 23 is fixedly connected to the lower end of the mounting base 17, and limiting grooves 25 are provided on the opposite side of the movable frame 22 and the fixed frame 23. The two limiting blocks 19 are respectively inserted into the two limiting grooves 25. The limiting mechanism also includes a driving mechanism.

[0030] In this embodiment: First, the wall panel 5 to be inspected is placed on top of the support frame 3, ensuring that the side of the wall panel 5 to be inspected faces upwards. The industrial camera 18 acquires images of the surface of the wall panel 5 and transmits the image data to a computer for processing and analysis.

[0031] When the image processing system analyzes the acquired image and determines that the wall panel 5 has a defect, the system immediately generates a defect confirmation electrical signal and transmits it to the controller 16. Upon receiving this trigger signal, the controller 16 immediately sends a start command to the ink delivery pump 9, driving it to begin operation. The ink delivery pump 9 draws ink from the ink tank 8 through the ink extraction tube 10, pumps it into the horizontal tube 6 through the bend tube 11, and finally sprays it onto the lower surface of the defective wall panel 5 through multiple micro-nozzles on the outer wall of the horizontal tube 6, thus completing the automatic marking. This process achieves automatic marking of defective products without manual intervention, is highly practical and easy to operate, and significantly improves sorting efficiency and accuracy.

[0032] On the other hand, when it is necessary to disassemble the industrial camera 18, the lead screw 21 is rotated within the mounting slot 20 by the drive mechanism. The lead screw 21 drives the movable frame 22 to move to the left along the slide rail. As the movable frame 22 moves, the limiting slot 25 on the movable frame 22 disengages from the left limiting block 19, thereby releasing the constraint on the industrial camera 18. Then, the right limiting block 19 disengages from the limiting slot 25 of the fixed frame 23, at which point the industrial camera 18 can be removed as a whole. The installation process is the reverse: the right limiting block 19 is aligned with the limiting slot 25 of the fixed frame 23 and inserted. The drive mechanism drives the lead screw 21 to rotate in the opposite direction, driving the movable frame 22 closer to the fixed frame 23, so that the left limiting block 19 enters the limiting slot 25 of the movable frame 22, and both the movable frame 22 and the fixed frame 23 are in contact with the industrial camera 18, thus completing the installation. This facilitates the disassembly and maintenance of the industrial camera 18, improving convenience.

[0033] As a technical optimization of this utility model, the drive mechanism includes a drive frame 26 fixedly connected to the outer wall of the mounting base 17, a worm gear 27 rotatably connected inside the drive frame 26, a worm wheel 24 meshing with the outer wall of the worm gear 27, a transmission shaft fixedly connected between the worm wheel 24 and the lead screw 21, and a handwheel extending to the outside of the drive frame 26 fixedly connected to the upper end of the worm gear 27.

[0034] In this embodiment: the worm 27 is driven to rotate by turning the handwheel, which in turn drives the worm wheel 24 to rotate, thereby causing the lead screw 21 to rotate within the mounting groove 20 via the transmission shaft. Since the worm 27 and worm wheel 24 have a self-locking characteristic, the lead screw 21 is prevented from rotating on its own, ensuring that the moving frame 22 does not move.

[0035] As a technical optimization of this utility model, the upper end of the support frame 3 is fixedly connected to a positioning frame 4 located outside the wall panel 5.

[0036] In this embodiment: the placement position of the wall panel 5 is positioned by setting the positioning frame 4.

[0037] As a technical optimization of this utility model, a slide rail is installed inside the mounting groove 20, and the movable frame 22 is slidably connected to the outer wall of the slide rail.

[0038] In this embodiment: Since the movable frame 22 is slidably connected to the outer wall of the slide rail, the movement of the movable frame 22 is ensured to be stable and without deviation.

[0039] As a technical optimization of this utility model, the upper end of the ink storage tank 8 is fixedly connected to the feeding port 12, the outer wall of the feeding port 12 is threadedly connected to the threaded cover 13, the upper end of the threaded cover 13 is provided with an installation port, and the interior of the installation port is fixedly connected to the ventilation mesh plate 14.

[0040] In this embodiment, the ventilation mesh plate 14 fixed inside the mounting opening on the threaded cover 13 adopts a microporous structure, which allows air to pass through to balance the air pressure inside the ink reservoir 8 and the outside, ensuring that the ink delivery pump 9 can smoothly draw ink, while effectively filtering dust in the air and preventing contaminants from entering the ink reservoir 8.

[0041] As a technical optimization of this utility model, two first fixing plates 7 are fixedly connected between the base plate 1 and the support plate 2. The ink delivery pump 9 is installed on the outer wall of the right first fixing plate 7. Two second fixing plates 15 are fixedly connected between the support plate 2 and the mounting base 17. The controller 16 is installed on the outer wall of the right second fixing plate 15. Multiple support columns are fixedly connected between the base plate 1 and the ink storage tank 8.

[0042] In this embodiment: two first fixing plates 7 are used to reinforce the connection between the base plate 1 and the support plate 2, and the right first fixing plate 7 provides an installation base for the ink delivery pump 9. Two second fixing plates 15 are used to enhance the structural strength between the support plate 2 and the mounting base 17, and the right second fixing plate 15 provides an installation position for the controller 16. Multiple support columns stably support the ink tank 8 above the base plate 1.

[0043] As a technical optimization of this utility model, the outer wall of the ink storage tank 8 is connected to an ink discharge pipe with a manual valve.

[0044] In this embodiment: when the device needs to replace ink or perform maintenance, the manual valve on the ink drain pipe connected to the outer wall of the ink tank 8 can be opened, and the residual ink in the tank can be completely discharged through the ink drain pipe under the action of gravity, which facilitates the cleaning and maintenance of the ink tank 8.

[0045] The working principle and usage process of this utility model are as follows: First, the wall panel 5 to be inspected is placed on the upper end of the support frame 3 and positioned by the positioning frame 4 to ensure the accuracy of the placement of the wall panel 5, ensuring that the side of the wall panel 5 to be inspected faces upwards. The industrial camera 18 acquires images of the surface of the wall panel 5 and transmits the image data to the computer for processing and analysis.

[0046] When the image processing system analyzes the acquired image and determines that the wall panel 5 has a defect, the system immediately generates a defect confirmation electrical signal and transmits it to the controller 16. Upon receiving this trigger signal, the controller 16 immediately sends a start command to the ink delivery pump 9, driving it to begin operation. The ink delivery pump 9 draws ink from the ink tank 8 through the ink extraction tube 10, pumps it into the horizontal tube 6 through the bend tube 11, and finally sprays it onto the lower surface of the defective wall panel 5 through multiple micro-nozzles on the outer wall of the horizontal tube 6, thus completing the automatic marking. This process achieves automatic marking of defective products without manual intervention, is highly practical and easy to operate, and significantly improves sorting efficiency and accuracy.

[0047] On the other hand, when it is necessary to disassemble the industrial camera 18, the worm gear 27 is driven to rotate by turning the handwheel. The worm gear 27 drives the worm wheel 24, which meshes with it, to rotate. This, in turn, causes the lead screw 21 to rotate within the mounting slot 20 via the transmission shaft. The lead screw 21 drives the movable frame 22 to move to the left along the slide rail. As the movable frame 22 moves, the limiting slot 25 on the movable frame 22 disengages from the left limiting block 19, thereby releasing the constraint on the industrial camera 18. Then, the right limiting block 19 disengages from the limiting slot 25 of the fixed frame 23, at which point the industrial camera 18 can be removed as a whole. The installation process is the reverse. The right limiting block 19 is aligned with the limiting slot 25 of the fixed frame 23 and inserted. The handwheel is then turned in the opposite direction to drive the movable frame 22 closer to the fixed frame 23, so that the left limiting block 19 enters the limiting slot 25 of the movable frame 22, and both the movable frame 22 and the fixed frame 23 are in contact with the industrial camera 18, thus completing the installation. This facilitates the disassembly and maintenance of the industrial camera 18, improving convenience.
