Description

Technical Field

[0001] The present invention relates to the technical field of plate production detection, and in particular to edge banding quality detection equipment. Background Art

[0002] Edge banding quality refers to the quality of panel edges after edge banding in industries such as furniture manufacturing and panel processing. It encompasses factors such as edge banding integrity, fit, smoothness, abrasion resistance, and color and texture matching with the substrate. Good edge banding quality improves product durability and aesthetics, preventing damage and moisture intrusion caused by untreated edges. Edge banding quality testing is the process of evaluating the quality of products after edge banding. Testing can determine whether the edge banding is uniform, fits tightly, and has a smooth surface, ensuring that the product meets design and usage requirements.

[0003] In the prior art, during the edge banding process of the plate, due to the influence of factors such as processing technology, equipment accuracy and operator's operating habits, there will be some differences in the edge banding quality of the four corners. Therefore, when the plate is subjected to edge banding quality inspection, after one of the corners has completed the appearance defect inspection, it is necessary to take out the plate, adjust the angle, and then put the plate back into the fixture to fix it, so as to perform edge banding quality inspection on the other corner. However, each time the plate is taken out, adjusted and re-fixed, it takes time. This frequent operation greatly increases the inspection time of a single plate and reduces the overall inspection efficiency. In addition, in the process of frequently taking out and re-placing the plate, it is easy to cause additional collisions, friction, etc. to the plate corners, affecting the original state of the corner edge banding, and thus affecting the accuracy of the inspection results.

[0027] 2. When the present invention is used, the two electromagnets are controlled to be energized to generate the same magnetism as the like-pole magnets, pushing the two like-pole magnets and the two movable plates to move upward, so that the reset spring is expanded, further pushing the clamping rod out, and clamping the plate on the fixed plate; starting the hydraulic cylinder, pushing the support seat, the rotating table and the clamped plate to move upward together; then starting the forward and reverse motors, driving the rotating table and the plate to rotate ninety degrees, and then the hydraulic cylinder moves downward and resets, driving the rotating table and the plate to move downward and reset together, and then starting the two fixing clamps again to clamp and fix the plate, and perform edge banding quality inspection on the other corner; under the action of the rotating assembly, the effect of automatic rotation is achieved, and the different angle states of the plate are automatically adjusted, without the need for frequent removal, adjustment, and re-insertion, saving time, improving detection efficiency, and avoiding accidental collision or friction of the plate during frequent removal and insertion, affecting the accuracy of the detection results.

[0028] 3.

[0042] The industrial camera 107 boasts high resolution and a high frame rate, enabling clear and rapid capture of details of the sheet edge banding, providing accurate image data for subsequent analysis. The ring light source 108 provides uniform and stable lighting for sheet edge inspection. By illuminating the sheet edge with multi-angle illumination, it highlights details such as the fit of the edge banding strips to the sheet edge, the surface smoothness, and color uniformity of the edge banding strips. This enhances image contrast and reduces shadow and reflection interference, enabling the industrial camera 107 to capture clear and accurate images, facilitating better observation and analysis of edge banding quality. The robotic arm 104 can flexibly adjust the position and angle of the industrial camera 107 and the ring light source 108 to capture comprehensive images of every part and angle of the sheet. The in-position sensor 109 monitors the motion of the robotic arm 104 in real time to ensure it is positioned correctly for image capture. When the robotic arm 104 reaches a preset position, the in-position sensor 109 sends a signal to the PLC controller 106, initiating the image capture process. This precise position feedback prevents collisions or improper operation of the robotic arm 104, ensuring the safety of the entire system.

There are ejection holes 308, two support plates 309 are set inside the rotating table 305, and two fixing columns 310 are fixedly installed on the top of the two support plates 309. The four fixing columns 310 are grouped into two longitudinally distributed fixed columns 310. The tops of the two groups of fixing columns 310 are fixedly installed with connecting plates 311, and the tops of the two connecting plates 311 are fixedly installed with electromagnets 312. The tops of the two electromagnets 312 are provided with movable plates 313. The bottoms of the two movable plates 313 are fixedly installed with same-sex magnets 314. The bottoms of the two same-sex magnets 314 are fixedly connected with anti-collision devices. The bottom of the two movable plates 313 is fixedly connected to the two sides with a return spring 316. The top of the two movable plates 313 is fixedly installed with two clamping rods 317. The tops of the four clamping rods 317 are fixed with a silicone sleeve 318. The bottom surface of the rotating table 305 is provided with two slide grooves 319. The bottom of one of the support plates 309 is fixedly installed with two slide rods 320. The bottom ends of the two slide rods 320 are respectively movably embedded in the inside of the two slide grooves 319. The top of the support seat 303 is provided with multiple ball grooves 321. The insides of the multiple ball grooves 321 are movable. Ball bearings 322 are embedded therein, and the outer surfaces of the multiple ball bearings 322 are in contact with the bottom of the rotating table 305. The bottoms of the two anti-collision soft strips 315 are in contact with the tops of the two electromagnets 312 respectively. The four return springs 316 are grouped together with two return springs 316 distributed longitudinally. One end of the two groups of return springs 316 are fixedly connected to the tops of the two support plates 309 respectively. The tops of the four silicone sleeves 318 are movably embedded in the two sliding holes 307 and the two ejection holes 308 respectively. The bottom of the other support plate 309 is installed on the bottom surface inside the rotating table 305 through an auxiliary rod.

[0046] In this embodiment, when in use, the control console 103, the robotic arm 104, the broadcaster 105, the industrial camera 107, the ring light source 108, the position sensor 109, the hydraulic cylinder 302, the forward and reverse motor 304, the electromagnet 312, the electric push rod 402 and the PLC controller 106 are electrically connected. The plate is placed on the inspection table 2 through the feed port 102 and pushed between the two guide bars 6, as shown in FIG. Figure 2As shown, the two fixing clamps 5 are then started through the control panel 103 to fix the plate on the top of the inspection table 2, and the industrial camera 107, the ring light source 108 and the robotic arm 104 are started. The industrial camera 107 takes pictures of the corners of the plate and transmits the image to the PLC controller 106 for identification and analysis. The PLC controller 106 has stored the defect-free standard edge banding image in advance. The PLC controller 106 will compare the captured edge banding image with the pre-stored defect-free standard edge banding image, and make a judgment based on the set defect feature threshold. If there is an area in the image that differs from the standard image by more than the threshold, it is determined that there is an appearance defect, and the detection result is broadcasted through the broadcaster 105, so that the operator can understand the general situation of the detection result at the first time without checking the specific detection data.

[0047] In this embodiment, the rotating assembly 3 adjusts the different states of the plate during use, so that the edge quality of the four corners of the plate can be tested. After the edge quality test of the plate corners is completed, the unloading assembly 4 cooperates to facilitate the staff to better remove the plate.

[0048] After the edge banding quality inspection is completed on one corner of the sheet, the two fixing clamps 5 are activated to move upward and reset. The two electromagnets 312 are then energized, generating a magnetic force with the same magnetic force as the like-pole magnets 314. Based on the principle that like charges repel, this magnetic force pushes the two like-pole magnets 314 upward together, thereby pushing the two movable plates 313 upward, causing the reset spring 316 to expand, further pushing the four clamping rods 317 upward from the corresponding sliding holes 307 and ejection holes 308, and positioning them on the four sides of the sheet, thereby clamping the sheet on the fixed plate 306. The hydraulic cylinder 302 is then activated, pushing the support base 303, the rotating platform 305, and the clamped sheet upward. When the hydraulic cylinder 302 automatically closes, the rotating platform 305 moves to the top of the guide bar 6, and the support base 303 moves into the embedded groove 7. Then start the forward and reverse motor 304, driving the rotating table 305 to rotate ninety degrees, and then driving the clamped plate to rotate ninety degrees, so that the other corner of the plate is rotated to the robotic arm 104. Under the action of the ball 322, it is beneficial for the rotating table 305 to rotate better and adjust the state of the plate. Then the hydraulic cylinder 302 moves downward and resets, driving the rotating table 305 and the plate to move downward and reset together, so that the rotating table 305 moves to the inside of the embedded groove 7 again, and the rotated plate enters between the two guide bars 6 again, and then the two fixing clamps 5 are started again to clamp and fix the plate. The edge banding quality inspection can be performed on the other corner of the plate. The output end of the forward and reverse motor 304 drives the rotating table 305 to stop automatically after each rotation of ninety degrees. When the rotating table 305 rotates three hundred and sixty degrees, the output end of the forward and reverse motor 304 will rotate three hundred and sixty degrees in the opposite direction, so that the rotating table 305 and the plate return to their initial state. Figure 5 As shown. Under the action of the rotating component 3, the automatic rotation effect is achieved, and the different angle states of the plate are automatically adjusted. There is no need to frequently remove, adjust, and put back, which saves time and improves detection efficiency. It prevents the plate from accidentally being hit or rubbed during the frequent removal and insertion process, which affects the accuracy of the detection results. It solves the problem that after the edge banding quality inspection of one corner of the plate is completed, the plate needs to be removed, the angle is adjusted, and then fixed again to inspect the other corner. This frequent operation not only takes a long time and has low detection efficiency, but also easily causes the plate corner to be hit or rubbed, affecting the original state of the corner edge banding, and thus affecting the accuracy of the detection results.

The interiors of the multiple ball grooves 321 are movably embedded with balls 322. The outer surfaces of the multiple balls 322 are in contact with the bottom of the rotating table 305. The blanking component 4 includes a mounting plate 401, and an electric push rod 402 is fixedly installed on the outer surface of one side of the mounting plate 401.

[0050] In this embodiment, when in use, after the edge banding quality inspection at the four corners of the plate is completed, the forward and reverse motors 304 will drive the plate to rotate to the initial state. Start the fixing clamp 5 and loosen the clamping of the plate. Then control the electromagnet 312 on the right to cut off the power, so that the magnetic force between the right electromagnet 312 and the right same-sex magnet 314 disappears, and the movable plate 313 on the right loses the pushing force. Under the elastic force of the reset spring 316, the right movable plate 313 is pulled downward to reset, and the two clamping rods 317 on the right are driven to move downward from the ejection hole 308 to reset. Under the protection of the anti-collision soft strip 315, the same-sex magnet 314 and the electromagnet 312 are prevented from collision and damage.

[0051] In this embodiment, the method and operating principle of the present invention are as follows: two fixing fixtures 5 are activated via the control console 103 to secure the sheet material to the top of the inspection table 2. An industrial camera 107 is activated to capture the sheet material's corners. The PLC controller 106 analyzes and compares the captured edge banding image with a pre-stored image of a defect-free standard edge banding, and the inspection results are broadcast via the broadcaster 105. A ring light source 108 provides uniform and stable lighting for sheet material edge banding inspection, enabling the industrial camera 107 to capture clear and accurate images, facilitating better observation and analysis of edge banding quality. The robotic arm 104 can flexibly adjust the position and angle of the industrial camera 107 and the ring light source 108 to capture comprehensive images of every part and angle of the sheet material. Simultaneously, a position sensor 109 monitors the movement of the robotic arm 104 in real time to ensure it is capturing images in the correct position. When the robotic arm 104 reaches a preset position, the position sensor 109 sends a signal to the PLC controller 106, initiating the image capture process. This precise position feedback prevents collisions or improper operation of the robotic arm 104, ensuring the safety of the entire system. After one corner of the sheet has completed edge banding quality inspection, the two fixed clamps 5 are activated to move upward and reset. Next, the two electromagnets 312 are energized, generating a magnetic force identical to that of the like-pole magnets 314. This forces the two like-pole magnets 314 and the movable plate 313 upward, causing the reset spring 316 to expand. This in turn pushes the four clamping rods 317 upward from their corresponding sliding holes 307 and ejection holes 308, positioning them on the four sides of the sheet, thereby clamping the sheet against the fixed plate 306. The hydraulic cylinder 302 is then activated, pushing the support base 303, the rotating platform 305, and the clamped sheet upward. When the hydraulic cylinder 302 automatically closes, the rotating platform 305 moves to the top of the guide bar 6, and the support base 303 moves into the embedded groove 7. The forward and reverse motors 304 are then activated, driving the rotating platform 305 to rotate 90 degrees, thereby rotating the clamped sheet 90 degrees, allowing the other corner of the sheet to rotate to the position of the robotic arm 104. Then the hydraulic cylinder 302 moves downward to reset, driving the rotating table 305 and the plate to move downward to reset, so that the rotating table 305 moves to the inside of the embedded groove 7 again, and the rotated plate enters between the two guide bars 6 again, and then the two fixing clamps 5 are started again to clamp and fix the plate. The edge banding quality inspection can be performed on the other corner of the plate. The output end of the forward and reverse motor 304 drives the rotating table 305 to stop automatically after each rotation of ninety degrees. When the rotating table 305 rotates three hundred and sixty degrees, the output end of the forward and reverse motor 304 will rotate three hundred and sixty degrees in the opposite direction, so that the rotating table 305 and the plate return to their initial state, as shown in FIG. Figure 5As shown. Start the fixing fixture 5 again to release the clamping fixation of the plate. Then control the electromagnet 312 on the right to cut off the power, and the movable plate 313 on the right loses the pushing force. Under the elastic force of the reset spring 316, the movable plate 313 on the right is pulled downward to reset, driving the two clamping rods 317 on the right to move downward from the ejection hole 308 to reset. Under the protection of the anti-collision soft strip 315, the collision damage between the same-sex magnet 314 and the electromagnet 312 is prevented. Then start the electric push rod 402, and through the cooperation of the pull plate 403 and the T-bar 404, pull the support plate 309 and the movable plate 313 on the left to move to the right, further driving the two clamping rods 317 on the left to slide in the corresponding sliding holes 307, pushing the plate to move to the right on the fixed plate 306, and further moving toward the feed port 102, so as to facilitate the staff to take out the plate, improve the safety of material collection, and make material collection more convenient.
