Therefore, it is necessary to detect the edge-sealing of the plates through a detection device to automatically detect defects such as chipping, high edge-sealing, low edge-sealing, long tape, short tape, edge-sealing tape damage, residual glue, overflow glue, glue seam, edge-sealing edge scratches, wavy patterns, and unsealing in the edge-sealing process.

[0048] For ease of explanation, in Figure 1A three-dimensional coordinate system is added, where the direction of the Z-axis is the first direction, which is the setting direction of the first dust-proof box 111 and the second dust-proof box 121. The direction of the X-axis is the second direction, which is the moving direction of the first dust-proof box 111. The direction of the Y-axis is the third direction, which is the moving direction of the board 20 on the edge banding device 30. Moreover, the first direction, the second direction, and the third direction are perpendicular to each other pairwise. Specifically, the first direction is the up-down direction.

[0049] This embodiment provides a detection device. The detection device is connected to the edge banding device 30 and is used for on-line detection of the edge banding defects of the board 20. The board 20 to be detected is edge banded on the edge banding device 30, and the edge banding device 30 is also used to transfer the board 20 along the third direction to the detection position 31, so as to facilitate the detection of the board 20 located at the detection position 31 by the detection device. Specifically, the edge banding of the board 20 has a lower surface, a side surface, and an upper surface. The lower surface, side surface, and upper surface of the board 20 are detected by the detection device. In addition, for the convenience of description, the lower surface, side surface, and upper surface of the board 20 pointed out in the following text are all defined as the lower surface, side surface, and upper surface at the edge banding of the board 20.

[0050] Please refer to Figure 1 , this embodiment provides a detection device. The detection device includes a first detection module 11 and a second detection module 12. The first detection module 11 includes a first dust-proof box 111, a lower surface detection component 112, and a side surface detection component 113. The first dust-proof box 111 is connected to the edge banding device 30. The lower surface detection component 112 and the side surface detection component 113 are arranged at intervals and installed inside the first dust-proof box 111. The lower surface detection component 112 is used to detect the lower surface of the board 20, and the side surface detection component 113 is used to detect the side surface of the board 20. The second detection module 12 includes a second dust-proof box 121 and an upper surface detection component 122. The second dust-proof box 121 is connected to the edge banding device 30. The upper surface detection component 122 is installed inside the second dust-proof box 121 and is used to detect the upper surface of the board 20. The first dust-proof box 111 is used to seal the lower surface detection component 112 and the side surface detection component 113. The second dust-proof box 121 is adjacent to the first dust-proof box 111 along the first direction and is used to seal the upper surface detection component 122.

[0051] When the above detection device is produced, first, the lower surface detection component 112 and the side surface detection component 113 are installed in the first dust-proof box 111, so as to facilitate the bearing and dust-proof sealing of the lower surface detection component 112 and the side surface detection component 113 through the first dust-proof box 111, and modular production of the first detection module 11 can also be carried out. Then, when the upper surface detection component 122 is installed in the second dust-proof box 121, so as to facilitate the bearing and dust-proof sealing of the upper surface detection component 122 through the second dust-proof box 121, and modular production of the second detection module 12 can also be carried out. Finally, the first detection module 11 and the second detection module 12 are assembled onto the edge sealing device 30 to complete the assembly production of the detection device. In this way, through the modular production of the first detection module 11 and the second detection module 12, the production efficiency of the detection device can be improved. At the same time, the detection device can also be assembled in a production line to facilitate the mass production of the detection device, thereby improving the production efficiency of the detection device.

[0052] Please refer to Figure 3 , in some embodiments, a first light-transmitting member 115 is embedded in the box wall of the first dust-proof box 111. The first light-transmitting member 115 is spaced from the lower surface of the plate 20 in a first direction. A second light-transmitting member 116 is also embedded in the box wall of the first dust-proof box 111. The second light-transmitting member 116 is spaced from the side surface of the plate 20 in a second direction perpendicular to the first direction. The optical path of the lower surface detection component 112 passes through the first light-transmitting member 115 and extends to the lower surface of the plate 20. The side surface detection component 113 passes through the second light-transmitting member 116 and extends to the side surface of the plate 20. Exemplarily, both the first light-transmitting member 115 and the second light-transmitting member 116 can be transparent glass.

[0053] In this way, by embedding the first light-transmitting member 115 and the second light-transmitting member 116 in the box wall of the first dust-proof box 111, on the basis of ensuring the sealing performance of the first dust-proof box 111, the optical path of the lower surface detection component 112 is realized to extend from the inside of the first dust-proof box 111 through the first light-transmitting member 115 to the outside of the first dust-proof box 111 and reach the lower surface of the plate 20, so that the lower surface detection component 112 inside the first dust-proof box 111 can detect the lower surface of the external plate 20. And the optical path of the side surface detection component 113 is realized to extend from the inside of the first dust-proof box 111 through the second light-transmitting member 116 to the outside of the first dust-proof box 111 and reach the side surface of the plate 20, so that the side surface detection component 113 inside the first dust-proof box 111 can detect the side surface of the external plate 20.

[0054] In some embodiments, a third light-transmitting member 124 is embedded in the box wall of the second dust-proof box 121. The third light-transmitting member 124 is spaced from the upper surface of the plate 20 in a first direction. The optical detection path of the upper surface detection assembly 122 passes through the third light-transmitting member 124 and extends to the upper surface of the plate 20. Exemplarily, the third light-transmitting member 124 may be a transparent glass.

[0055] Thus, by embedding the third light-transmitting member 124 in the box wall of the second dust-proof box 121, on the basis of ensuring the sealing performance of the second dust-proof box 121, the optical path of the upper surface detection assembly 122 extends from the inside of the second dust-proof box 121 through the third light-transmitting member 124 to the outside of the second dust-proof box 121 and reaches the upper surface of the plate 20, so that the upper surface detection assembly 122 inside the second dust-proof box 121 can detect the upper surface of the external plate 20.

[0056] In some embodiments, the detection device further includes a light supplement member 13. The light supplement member 13 is disposed in the first dust-proof box 111 and is close to the second light-transmitting member 116. The light beam generated by the light supplement member 13 irradiates the upper surface, lower surface and side surface of the plate 20.

[0057] Thus, by using the light supplement member 13 to supplement light to the lower surface, side surface and upper surface of the plate 20, the lower surface detection assembly 112, the side surface detection assembly 113 and the upper surface detection assembly 122 can more clearly capture the images on the lower surface, side surface and upper surface of the plate 20, thereby improving the detection accuracy.

[0058] In this embodiment, the light supplement member 13 includes a light supplement frame 131 and a light source member 132. The light supplement frame 131 is connected to the box wall of the first dust-proof box 111. The light source member 132 is connected to the light supplement frame 131. The light source member 132 is disposed offset from the side surface detection assembly 113 in a second direction to avoid the light source member 132 blocking the optical path of the side surface detection assembly 113. Exemplarily, the light source member 132 may be an LED lamp.

[0059] Furthermore, the light supplement frame 131 is slidably connected to the first dust-proof box 111 in the second direction. The light source member 132 is inclined in a third direction with respect to the second direction, so that when the light source member 132 moves along the second direction following the light supplement frame 131, the light beam generated by the light source member 132 irradiates different positions on the plate 20, thereby adjusting the light supplement position of the light supplement member 13.

[0060] In some embodiments, the first detection module 11 further includes a first transfer component 114. The first transfer component 114 includes a first slide 1141 and a first sliding member 1142. The first slide 1141 is disposed on a side of the first dust-proof box 111 facing away from the second dust-proof box 121 and is connected to the edge banding device 30. The first slide 1141 extends along a second direction perpendicular to the first direction, and the first sliding member 1142 is connected to the first dust-proof box 111 and slidably connected to the first slide 1141.

[0061] In this way, when moving the first detection module 11 away from the detection position 31 of the edge banding device 30, the first dust-proof box 111 is driven by an external force to drive the first sliding member 1142 to slide along the first slide 1141, so as to support the first dust-proof box 111 to slide stably along the second direction through the first slide 1141, thereby improving the smoothness of the first detection module 11 when sliding.

[0062] In this embodiment, the first sliding member 1142 and the first dust-proof box 111 are detachably connected by bolts, so as to facilitate the assembly of the first sliding member 1142 and the first dust-proof box 111.

[0063] In this embodiment, the first transfer component 114 further includes a first positioning member 1143. The first positioning member 1143 is used to position the first detection module 11 that moves to the detection position 31 on the edge banding device 30 along the second direction.

[0064] Further, the first positioning member 1143 can be a stop block or a displacement sensor. Among them, the installation processes of the stop block and the displacement sensor are both conventional means in the art.

[0065] In some embodiments, the second detection module 12 further includes a second transfer component 123. The second transfer component 123 includes a second slide 1231 and a second sliding member 1232. The second slide 1231 is disposed on a side of the second dust-proof box 121 facing away from the first dust-proof box 111 and is connected to the edge banding device 30. The second slide 1231 extends along the second direction, and the second sliding member 1232 is connected to the second dust-proof box 121 and slidably connected to the second slide 1231.

[0066] In this way, when moving the second detection module 12 away from the detection position 31 of the edge banding device 30, the second dust-proof box 121 is driven by an external force to drive the second sliding member 1232 to slide along the second slide 1231, so as to support the second dust-proof box 121 to slide stably along the second direction through the second slide 1231, thereby improving the stability of the second detection module 12 when sliding.

[0067] In this embodiment, the second sliding member 1232 and the second dust-proof box 121 are detachably connected by bolts, so as to facilitate the assembly of the first sliding member 1142 and the second dust-proof box 121.

[0068] In this embodiment, the first transfer component 114 further includes a second positioning member 1233, and the second positioning member 1233 is used to position the first detection module 11 that moves to the detection position 31 on the edge sealing device 30 along the second direction.

[0069] Furthermore, the second positioning member 1233 can be a stopper or a displacement sensor. Among them, the installation processes of the stopper and the displacement sensor are both conventional means in the art.

[0070] In some embodiments, the second dust-proof box 121 is slidably connected to the first dust-proof box 111 along a second direction perpendicular to the first direction; in this way, when the second dust-proof box 121 is slid along the second direction by an external force, the first dust-proof box 111 can stably support the second dust-proof box 121, thereby improving the stability of the second dust-proof box 121 when sliding. At the same time, since the first dust-proof box 111 and the second dust-proof box 121 are slidably connected, the first dust-proof box 111 and the second dust-proof box 121 can move independently in the second direction without movement interference.

[0071] It can be understood that during the detection process, it is necessary to regularly pull out the first detection module 11 and the second detection module 12 along the second direction, so as to remove the first light-transmitting member 115 and the second light-transmitting member 116 on the first dust-proof box 111, and the third light-transmitting member 124 on the second dust-proof box 121 for cleaning, so as to ensure the light transmittance of the first light-transmitting member 115, the second light-transmitting member 116 and the third light-transmitting member 124, and thus ensure the stability of the detection.

[0072] In some embodiments, the lower surface detection assembly 112 includes a first reflector 1121, a first mounting bracket 1122, a first vision detection member 1123, and a first laser detection member 1124. The first reflector 1121 is connected to the inside of the first dust-proof box 111 and is spaced from the first light-transmitting member 115 in a first direction. Specifically, the reflecting surface of the first reflector 1121 is inclined in a second direction in the first direction. The first mounting bracket 1122 is connected to the inside of the first dust-proof box 111. The first vision detection member 1123 is connected to the first mounting bracket 1122 and is spaced from the first reflector 1121 in a second direction. The first vision detection member 1123 is used to perform light-emitting detection on the lower surface of the sheet 20. The first laser detection member 1124 is disposed adjacent to the first vision detection member 1123 and is connected to the first mounting bracket 1122. The first laser detection member 1124 is used to perform light-emitting operation on the lower surface of the sheet 20. The optical path of the first vision detection member 1123 is parallel to the optical path of the first laser detection member 1124, and the optical paths of the first vision detection member 1123 and the first laser detection member 1124 both extend in the second direction to the first reflector 1121 and are reflected by the first reflector 1121 and then extend in the first direction to the lower surface of the sheet 20. Exemplarily, the first reflector 1121 may be a reflecting mirror, the first vision detection member 1123 may be an optical detection camera, and the first laser detection member 1124 may be a laser emitter.

[0073] When the lower surface detection assembly 112 operates, the optical beam bundles generated by the first vision detection member 1123 and the first laser detection member 1124 are both irradiated onto the first reflector 1121 in the second direction and are reflected by the first reflector 1121 and vertically irradiated onto the lower surface of the sheet 20 in the first direction, so as to realize the detection of the lower surface of the sheet 20. In this way, the optical beam bundles generated by the first vision detection member 1123 and the first laser detection member 1124 installed inside the first dust-proof box 111 can be vertically irradiated on the lower surface of the sheet 20, so as to reduce the scattering generated on the lower surface after the optical beam bundle is excited, making it easier to obtain the defect image of the lower surface, and thus being beneficial to improving the detection accuracy.

[0074] In this embodiment, the first mounting bracket 1122 is detachably connected to the inner wall of the first dust-proof box 111.

[0075] In some embodiments, the side surface detection component 113 includes a second mounting bracket 1131, a second vision detection member 1132, and a second laser detection member. The second mounting bracket 1131 is connected inside the first dust-proof box 111 and is spaced apart from the first mounting bracket 1122 in the first direction. The second vision detection member 1132 is connected to the second mounting bracket 1131. The second vision detection member 1132 is used to perform lighting detection on the side surface of the sheet 20, and the optical path of the second vision detection member 1132 extends in the second direction to the side surface of the sheet 20. Exemplarily, the second vision detection member 1132 can be an optical detection camera, and the second laser detection member can be a laser emitter.

[0076] When the side surface detection component 113 operates, the optical beam generated by the second vision detection member 1132 is vertically irradiated on the side surface of the sheet 20 in the second direction, thereby realizing the detection of the side surface of the sheet 20. In this way, the optical beam generated by the second vision detection member 1132 installed inside the first dust-proof box 111 can be vertically irradiated on the side surface of the sheet 20, so as to reduce the scattering generated on the side surface after the optical beam is excited, making it easier to obtain the defect image of the side surface, and thus being beneficial to improving the detection accuracy.

[0077] In this embodiment, the second mounting bracket 1131 is detachably mounted on the inner wall of the first dust-proof box 111.

[0078] In some embodiments, the upper surface detection component 122 includes a second reflector 1221, a third mounting bracket 1222, a third vision detection member 1223, and a third laser detection member 1224. The second reflector 1221 is connected inside the second dust-proof box 121 and is spaced apart from the third light-transmitting member 124 in the first direction. Specifically, the reflecting surface of the second reflector 1221 is inclined in the first direction towards the second direction. The third mounting bracket 1222 is connected inside the second dust-proof box 121. The third vision detection member 1223 is connected to the third mounting bracket 1222 and is spaced apart from the second reflector 1221 in the second direction perpendicular to the first direction. The third vision detection member 1223 is used to perform lighting detection on the upper surface of the sheet 20. The third laser detection member 1224 is adjacent to the third vision detection member 1223 and is connected to the third mounting bracket 1222. The third laser detection member 1224 is used to perform lighting operation on the upper surface of the sheet 20. The optical path of the third vision detection member 1223 is parallel to the optical path of the third laser detection member 1224, and the optical paths of both the third vision detection member 1223 and the third laser detection member 1224 extend in the second direction to the second reflector 1221 and are reflected by the second reflector 1221 and then extend in the first direction to the upper surface of the sheet 20. Exemplarily, the third vision detection member 1223 can be a camera, and the third laser detection member 1224 can be a laser emitter.

[0079] When the upper surface detection component 122 is operating, the optical beams generated by the third visual detection component 1223 and the third laser detection component 1224 are irradiated onto the first reflective component 1121 along the second direction, and are reflected by the first reflective component 1121 to irradiate vertically along the first direction onto the upper surface of the plate 20, thereby realizing the detection of the upper surface of the plate 20. In this way, the optical beams generated by the third visual detection component 1223 and the third laser detection component 1224 installed inside the second dustproof box 121 can be irradiated vertically onto the upper surface of the plate 20, so as to reduce the scattering generated on the upper surface after the optical beam is excited, thereby making it easier to capture the defect image of the upper surface, which is beneficial to improve the detection accuracy.

[0080] In this embodiment, the third mounting bracket 1222 is detachably mounted on the inner wall of the second dustproof box 121 .

[0081] The working principle of the above detection device is roughly as follows:

[0082] The first detection module 11 is moved to the detection position 31 of the edge banding device 30 along the first slide 1141 by a positive external force, and then the lower surface detection component 112 and the side surface detection component 113 sealed inside the first dustproof box 111 are used to detect the lower surface and the side surface of the plate 20 respectively, thereby realizing dustproof protection for the lower surface detection component 112 and the side surface detection component 113 in the detection state;

[0083] The second detection module 12 is moved by a positive external force to move along the second slide 1231 to the detection position 31 of the edge banding device 30, and then the upper surface detection component 122 sealed inside the second dustproof box 121 is used to detect the upper surface of the plate 20, thereby realizing dustproof protection for the upper surface detection component 122;

[0084] By using reverse external force, the first detection module 11 is pushed along the first slide 1141 to move away from the detection position 31 of the edge sealing device 30, so as to clean the first light-transmitting member 115 and the second light-transmitting member 116 on the first dust-proof box 111. By using reverse external force, the second detection module 12 is pushed along the second slide 1231 to move away from the detection position 31 of the edge sealing device 30, so as to clean the third light-transmitting member 124 on the second dust-proof box 121.

[0085] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
