[0002] Generally, an edge banding machine is required to perform edge banding on the outer edge of the board. During the use of the edge banding machine, the temperature of the glue in the glue coating device will be low due to the low ambient temperature, which will cause the edge banding machine to not work normally.

The light source assembly 404 is located on one side of the visual inspection device 402. The light source assembly 404 cooperates with the visual inspection device 402. Both partitions 403 are provided with a light-transmitting surface 408.

[0035] The transmission channel 405 formed between the two partitions 403 is used to transmit the plate 7. Specifically, the plate 7 is transported in the transmission channel 405 by the transmission device 2, that is, the plate 7 that has completed the dust removal process is transmitted to the transmission channel 405 via the conveyor belt 201. The two light source assemblies 404 in this embodiment are respectively matched with the visual detection device 402 located in the same chamber, providing sufficient shooting light for the visual detection device 402, so that the visual detection device 402 works in a better shooting environment. Since the first installation chamber 406 and the second installation chamber 407 are respectively located on both sides of the transmission channel 405, that is, the two visual inspection devices 402 are respectively located on both sides of the transmission channel 405, when the plate 7 is located in the transmission channel 405, light enters or leaves the chamber corresponding to the partition 403 where the light-transmitting surface 408 is located through the light-transmitting surface 408, so that the two visual inspection devices 402 can perform visual inspection on the upper and lower side edge sealing openings of the same edge sealing strip of the plate 7. Compared with the existing technology, the degree of automation is higher, and the plate 7 can be effectively detected for edge sealing defects to avoid missed detection and false detection, which is beneficial to improving detection efficiency and product quality.

[0036] Specifically, the transmission channel 405 is arranged horizontally, the first installation chamber 406 is located on the lower side of the transmission channel 405, the second installation chamber 407 is located on the upper side of the transmission channel 405, the two visual inspection devices 402 are respectively fixedly connected to the fixed frame 401, and the two light source assemblies 404 are respectively fixedly connected to the fixed frame 401, and the light source assembly 404 is located on the side of the visual inspection device 402 close to the partition 403.

[0037] It should be noted that the two partitions 403 are staggered.

[0038] More specifically, the two partitions 403 are parallel to each other.

[0039] It should be emphasized that the light source assembly 404 includes two symmetrically arranged imaging light sources 409 , and the two imaging light sources 409 are fixedly connected to the fixed frame 401 respectively.

[0040] It is worth mentioning that the axis of the imaging light source 409 intersects with the axis of the partition 403 .

[0041] In addition, the visual inspection device 402 includes a camera lens 410, which is fixedly connected to the fixed frame 401, and two camera light sources 409 are located on one side of the camera lens 410 close to the partition 403. It can be understood that the visual inspection device 402 also includes a camera, the camera lens 410 is arranged on the camera, the camera is fixed on the fixed frame 401, and the camera is connected to the control system.

[0042] Furthermore, two imaging light sources 409 are arranged on the fixed frame 401 at a relative inclination, and the two imaging light sources 409 respectively form an inclination angle with the partition 403 located on one side thereof, and the inclination angle is preferably an acute angle. The axes of the two imaging light sources 409 and the axis of the camera lens 410 intersect at the same point on the same plane, that is, cross lighting is achieved for the plate 7. This lighting method is beneficial to improving detection efficiency.

[0043] In addition, the board edge defect detection device 4 also includes a dust scraping device, which cooperates with the light-transmitting surface 408 and is used to remove dust on the light-transmitting surface 408. Specifically, the dust scraping device can be driven to move on the light-transmitting surface 408 so that the scraper contacts the surface of the light-transmitting surface 408, thereby removing dust on the light-transmitting surface 408 to prevent dust from adhering to the light-transmitting surface 408 and affecting the detection result, so that the board 7 can be effectively detected.

[0044] In this embodiment, the light-transmitting surface 408 on the partition 403 is preferably made of a material with high light transmittance, such as glass, so that the light-transmitting surface 408 has a high light transmittance, which is beneficial to improving the detection efficiency.

[0045] A limiting portion 411 is provided on the fixed frame 401 in this embodiment, and the limiting portion 411 is located on the transmission channel 405. More specifically, an arc-shaped edge is provided on the limiting portion 411, and the arc-shaped edge abuts against the outer edge of the plate 7, so that the plate 7 in the transmission channel 405 can be limited, which can effectively prevent the plate 7 from being offset, and is beneficial to improving the detection effect.

[0046] When in use, the transmission device 2 transmits the plate 7, and the two camera lenses 410 are respectively located on the upper and lower sides of the plate 7. The light beams F1 emitted by the two camera light sources 409 hit the edge banding strip of the plate 7 to form a light spot. The light beam F2 reflected at the light spot enters the camera lens 410, and the camera lens 410 moves to obtain images of the edge banding openings on both sides of the same edge banding strip of the plate 7, and then the camera sends the image to the control system, which processes and analyzes the image. As the plate 7 moves, the two visual inspection devices 402 can complete the inspection of the entire edge banding strip on the plate 7, thereby being able to effectively detect edge banding defects on the plate 7 to avoid missed inspections and false inspections, which is beneficial to improving inspection efficiency and product quality.

[0048] The labeling tape 522 is wound around the release wheel 503, the label lifting piece 504, and the winding wheel 502. The winding wheel 502 rotates, driving the labeling tape 522 to rotate, so that the labeling tape 522 is transported toward the winding wheel 502. When the label 523 on the labeling tape 522 passes the label lifting piece 504, the label 523 falls off from the labeling tape 522 under the action of the label lifting piece 504. Since the label suction mechanism is connected with the label lifting piece 504, the detached label 523 is located at the lower side of the label suction mechanism, and the label suction mechanism works to suck the label 523. In the plate 7 edge defect detection machine, the conveyor belt 201 transports the plate 7, the plate 7 is in a moving state, and the label 523 is in a relatively static state. The label pressing mechanism works to fix the plate 7 so that the label 523 is in close contact with the plate 7, thereby completing the labeling action. Through the cooperation of the label suction mechanism and the label pressing mechanism, the plate 7 can be effectively labeled to avoid the phenomenon of missing, crooked, and unstable label 523, which can effectively distinguish defective products from qualified products, and is conducive to improving labeling efficiency.

[0058] When in use, the driving member 520 rotates the reel 502, driving the labeling tape 522 to rotate, so that the labeling tape 522 is transported toward the reel 502. When the label 523 on the labeling tape 522 passes the label lifting member 504, the label 523 falls off from the labeling tape 522 under the action of the label lifting member 504. The detached label 523 is located at the lower side of the label suction member 505. The vacuum generator 506 works to form a negative pressure state on the lower end surface of the label suction member 505 through the suction hole 507. state, generating a certain suction force to suck the label 523. Since the plate 7 is in a moving state during the transmission process, the cylinder 508 works, and the cylinder 508 drives the connecting rod connected to it to push out, so that the fixed plate 509 descends and contacts the label 523. The two label pressing rollers 510 press the label 523 on the surface of the plate 7 and fix the plate 7 at the same time to prevent the label 523 from being missed, crookedly pasted, or unstable, so that the label 523 is closely attached to the surface of the plate 7, and the efficiency of labeling 523 is high.

[0059] When it is necessary to replace the label 523, the lifting plate 519 is lifted upward by the gripping piece 521, that is, the lifting plate 519 moves away from the mounting plate 512, and the lifting plate 519 drives the connecting column 515 to lift upward, and the connecting column 515 drives the connecting plate 517 to move synchronously, that is, the connecting plate 517 moves toward the direction close to the fixed sleeve 513, and the spring 516 is compressed under the action of the fixed sleeve 513 and the connecting plate 517, and the movable sleeve 514 moves synchronously with the connecting plate 517, and the connecting plate 517 drives the two pressing wheels 518 to move synchronously, so that the two pressing wheels 518 move away from the passing wheel 511, so that the two pressing wheels 518 are separated from the passing wheel 511, workers can replace the labeling tape 522.

[0061] A better implementation is that the transmission device 2 in this embodiment also includes a movable plate 202 and a plurality of driven wheels 203, the movable plate 202 is located on the upper side of the conveyor belt 201, the driven wheels 203 are located between the movable plate 202 and the conveyor belt 201, and the driven wheels 203 are rotatably mounted on the movable plate 202, and the above-mentioned driven wheels 203 are in contact with the upper surface of the plate 7, in transmission contact with the plate 7 and apply pressure to the surface of the plate 7, that is, the movement of the plate 7 enables the driven wheels 203 to obtain rotational power, which is beneficial to improving the conveying efficiency of the plate 7.

[0062] like Figure 1 and Fig.10 As shown, the plate 7 edge banding defect detection machine also includes a pressure regulating device 6, which includes a fixed seat 601, a lifting mechanism 602, a guide rod 603 and a connecting block 604. The fixed seat 601 is separated from the bracket 501, and the fixed seat 601 is fixedly connected to the frame 1. The lifting mechanism 602 is arranged on the fixed seat 601, and the guide rod 603 is connected to the output end of the lifting mechanism 602. The lifting mechanism 602 drives the guide rod 603 to rise or fall along its axial direction. The connecting block 604 is arranged on the guide rod 603, that is, the guide rod 603 can drive the connecting block 604 to rise or fall synchronously, and the movable plate 202 is fixedly connected to the connecting block 604, so that the lifting mechanism 602 can drive the movable plate 202 to move towards or away from the conveyor belt 201, so as to adjust the distance between the movable plate 202 and the conveyor belt 201, and also to adjust the distance between the driven wheel 203 and the plate 7, so that the pressure applied by the driven wheel 203 to the surface of the plate 7 can be adjusted. In addition, when maintenance is required, the movable plate 202 is moved away from the conveyor belt 201 through the lifting mechanism 602, and the movable plate 202 is raised to a certain height, which can provide workers with sufficient maintenance space, thereby improving maintenance efficiency.

[0063] In this embodiment, there are two pressure regulating devices 6, which are respectively located on both sides of the labeling device 5. The two pressure regulating devices 6 are helpful for achieving smooth lifting and lowering of the movable plate 202 and improving the regulating efficiency.
