Description

Technical Field

[0001] The 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 the edge of the board after edge banding in the furniture manufacturing, board processing and other industries. It includes factors such as edge banding integrity, fit, smoothness, wear resistance, and the degree of matching with the base material color and texture. Good edge banding quality can improve the durability and aesthetics of the product and avoid damage or moisture intrusion caused by untreated edges. Edge banding quality testing is the process of evaluating the quality of the product after the edge banding process is implemented. Through testing, it can be found whether the edge banding is uniform, whether the fit is tight, whether the surface is smooth, etc., to ensure that the product meets the design and use requirements.

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

The top of the two groups of fixed columns 310 are fixedly installed with a connecting plate 311, and the top of the two connecting plates 311 are fixedly installed with an electromagnet 312, and the top of the two electromagnets 312 is provided with a movable plate 313, and the bottom of the two movable plates 313 is fixedly installed with a same-sex magnet 314, and the bottom of the two same-sex magnets 314 is fixedly connected with an anti-collision device. The bottom of the two movable plates 313 is fixedly connected with a return spring 316 near both sides, the top of the two movable plates 313 is fixedly installed with two clamping rods 317, and the tops of the four clamping rods 317 are fixedly covered with a silicone sleeve 318. The bottom surface of the rotating table 305 is provided with two slide grooves 319, and 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 a plurality of ball grooves 321, and the insides of the plurality of 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. Four return springs 316 are arranged in a group with two return springs 316 distributed longitudinally.

[0027] In this embodiment, when in use, the control console 103, the mechanical arm 104, the broadcaster 105, the industrial camera 107, the annular light source 108, the in-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 fixtures 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 robot 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 stores the defect-free standard edge banding image in advance. The PLC controller 106 will compare the captured edge banding part 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 played 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.

[0028] In this embodiment, when in use, the rotating assembly 3 adjusts the different states of the plate, so that the edge quality inspection can be performed on the four corners of the plate. After completing the edge quality inspection of the plate corners, the unloading assembly 4 cooperates to facilitate the staff to take out the plate better.

[0029] After the edge quality inspection of one corner of the plate is completed, the two fixing clamps 5 are started to move upward and reset. Then, the two electromagnets 312 are controlled to be energized to generate a magnetic force with the same magnetic properties as the magnets 314 of the same sex. According to the principle that like repels like, the magnetic force will push the two magnets 314 of the same sex to move upward together, thereby pushing the two movable plates 313 to move upward, so that the reset spring 316 is unfolded, and further pushes the four clamping rods 317 to be ejected upward from the corresponding sliding holes 307 and ejection holes 308, located on the four sides of the plate, thereby clamping the plate on the fixed plate 306. Then, the hydraulic cylinder 302 is started to push the support seat 303, the rotating table 305 and the clamped plate to move upward together. When the hydraulic cylinder 302 is automatically closed, the rotating table 305 moves to the top of the guide bar 6, and the support seat 303 moves to 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 mechanical arm 104. Under the action of the ball 322, the rotating table 305 can 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 rotating 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 take out, adjust, and put in again, which saves time, improves the detection efficiency, and avoids the plate from being accidentally hit or rubbed during the frequent taking out and putting in, which affects the accuracy of the detection result. It solves the problem that when one corner of the plate completes the edge sealing quality inspection, the plate needs to be taken out, adjusted and fixed again, so as to detect the other corner. This frequent operation not only takes a long time and has low detection efficiency, but also easily causes the corner of the plate to be hit or rubbed, affecting the original state of the corner edge sealing, and thus affecting the accuracy of the detection result.

[0031] In this embodiment, when in use, after the edge quality inspection of 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 fixture 5 to loosen the clamping fixation of the plate. Then control the electromagnet 312 on the right side to cut off the power, so that the magnetic force between the electromagnet 312 on the right side and the same-sex magnet 314 on the right side disappears, and the movable plate 313 on the right side loses the thrust force.

Through accurate position information feedback, the mechanical arm 104 is prevented from colliding or improper operation, ensuring the safety of the overall system. After the edge quality inspection of one corner of the plate is completed, the two fixing clamps 5 are started to move upward and reset. Then, the two electromagnets 312 are controlled to be energized to generate a magnetic force with the same magnetic force as the same-sex magnet 314, pushing the two same-sex magnets 314 and the movable plate 313 to move upward, so that the reset spring 316 is unfolded, and further pushes the four clamping rods 317 to be ejected upward from the corresponding sliding holes 307 and ejection holes 308, located on the four sides of the plate, thereby clamping the plate on the fixed plate 306. Then, the hydraulic cylinder 302 is started to push the support seat 303, the rotating table 305 and the clamped plate to move upward together. When the hydraulic cylinder 302 is automatically closed, the rotating table 305 moves to the top of the guide bar 6, and the support seat 303 moves to the embedded groove 7. Then, the forward and reverse motors 304 are started to drive the rotating table 305 to rotate 90 degrees, thereby driving the clamped plate to rotate 90 degrees, so that the other corner of the plate rotates to the mechanical 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, such as 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 be powered off, 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, 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 drive the two clamping rods 317 on the left to slide in the corresponding sliding holes 307, push the plate to move to the right on the fixed plate 306, and further move to 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.
