The unloading platform is then moved downwards by a moving unloading mechanism to unload the board. This automatic visual inspection system saves significant manpower and resources, ensures consistent inspection standards, reduces the risk of missed or incorrect inspections, and minimizes the flow of defective products, thus guaranteeing product quality.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides an automatic appearance inspection device, including a frame 100, and a docking and feeding unit 200, a front and back inspection unit 300, a side inspection unit 400, and a unloading unit 500 sequentially arranged on the frame 100. The docking and feeding unit 200 feeds the flexible board to be inspected, conveying it to the front and back inspection unit 300 for appearance inspection of the front and back sides of the flexible board. The side inspection unit 400 inspects the sides of the flexible board. The unloading unit 500 unloads the inspected flexible board.

[0039] Specifically, the frame 100 includes a base frame 110 and a top frame 120 protruding from the base frame 110. Furthermore, the base frame 110 may sequentially include a loading station, a first inspection station, a second inspection station, and a unloading station. The loading unit 200 may include a loading movement drive mechanism 210 located at the loading station on the base frame 120, and a loading platform 220 connected to the loading movement drive mechanism 210. The front and back inspection unit 300 may include a material flipping and conveying mechanism 310 located at the first and second inspection stations on the base frame 110, and a front and back visual inspection mechanism 320 located on the top frame 120. The front and back visual inspection mechanism 320 is vertically corresponding to the loading platform 220, and the material flipping and conveying mechanism 310 is located on the outer side of the loading platform 220. The side inspection unit 400 may include a rotating platform 410 located at the second inspection station of the base frame 110, and a side visual inspection mechanism 420 located on the top frame 120. The rotating platform 410 is correspondingly engaged with the material flipping and conveying mechanism 310, and the side visual inspection mechanism 420 is vertically aligned with the rotating platform 410. The unloading unit 500 may include an unloading moving drive mechanism 510 located at the unloading station of the base frame 110, and an unloading platform 520 connected to the unloading moving drive mechanism 510. The unloading platform 520 is correspondingly engaged with the material flipping and conveying mechanism 310.

[0040] The loading platform 220, connected to the loading unit 200, can receive external flexible boards to be inspected. The loading platform 220 and the flexible boards to be inspected are then driven by the loading movement drive mechanism 210 to transport them to the front and back inspection unit 300. The front and back visual inspection mechanism 320 of the front and back inspection unit 300 performs visual inspection on the front of the flexible board on the loading platform 220. Then, the material flipping and transfer mechanism 310 flips the flexible board so that the back side is facing up. Finally, the front and back visual inspection mechanism 320 inspects the back side of the flexible board. The process involves several steps: First, an appearance inspection is performed. After inspecting the front and back of the flexible board, the material transfer mechanism 310 transfers the board to be inspected onto the rotating platform 410 of the side inspection unit 400. The rotating platform 410 rotates the board, and the side visual inspection mechanism 420 performs an appearance inspection on its sides. After the side inspection, the material transfer mechanism 310 transfers the board to the unloading platform 520 of the unloading unit 500, and the unloading movement drive mechanism 510 moves the unloading platform 520 downwards to unload the board. This automatic appearance inspection system saves significant manpower and resources, ensures consistent inspection standards, reduces the likelihood of missed or incorrect inspections, and minimizes the outflow of defective products, thus guaranteeing product quality.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the loading movement drive mechanism 210 of the docking loading unit 200 may include a transverse loading drive structure 212 disposed at the loading station on the base frame 110, and the loading platform 220 is connected to the transverse loading drive structure 212. The transverse loading drive structure 212 can drive the loading platform 220 to move reciprocally along the transverse side of the frame 100, thereby driving the loading platform 220 to move reciprocally between the loading station and the first inspection station. Specifically, the transverse loading drive structure 212 may include a transverse loading guide rail 2124 disposed on the base frame 110 and a transverse loading drive component 2122, the loading platform 220 is slidably disposed on the transverse loading guide rail 2124, and the transverse loading drive component 2122 is connected to the loading platform 220. The transverse feeding guide rail 2124 extends laterally between the feeding station and the first inspection station, allowing the transverse feeding drive 2122 to drive the feeding platform 220 to reciprocate between the feeding station and the first inspection station. The transverse feeding drive 2122 can be configured as a cylinder-driven structure.

[0042] Furthermore, the loading platform 220 may include a loading bracket 222 slidably mounted on a transverse loading guide rail 2124, and a loading carrier plate 224 mounted on the loading bracket 222. The loading carrier plate 224 can be used to hold the flexible plate to be tested. In addition, a limiting groove may be provided on the loading carrier plate 224 for positioning and limiting the flexible plate to be tested.

[0043] In addition, such as Figure 5 and Figure 6 As shown, the material flipping and conveying mechanism 310 of the front and back detection unit 300 may include a material transverse movement driving mechanism 312 disposed at the first detection station and the second detection station of the base frame 110, and a material flipping mechanism 314 and a material translation mechanism 316 disposed sequentially on the material transverse movement driving mechanism 312. The material flipping mechanism 314 can be correspondingly matched with the loading platform 220 and the rotating platform 410, and the material translation mechanism 316 can be correspondingly matched with the loading platform 220, the rotating platform 410 and the unloading platform 520. The material transverse drive mechanism 312 can drive the material flipping mechanism 314 and the material translation mechanism 316 to reciprocate between the loading station, the first inspection station, the second inspection station, and the unloading station. This facilitates moving the flexible board to be inspected to the first inspection station and the second inspection station for appearance inspection. The material flipping mechanism 314 facilitates flipping the flexible board to be inspected, allowing for inspection of both the front and back sides of the board. The material translation mechanism 316 facilitates moving the flexible board from the first inspection station to the second inspection station for side inspection, and also facilitates moving the flexible board from the second inspection station to the unloading station for unloading.

[0044] Furthermore, the material transverse movement drive mechanism 312 may include a material transverse movement bracket 3122 mounted on the base frame 110, a material transverse movement guide rail 3124 and a material transverse movement drive component 3126 mounted on the material transverse movement bracket 3122, and a material transverse movement base 3128 slidably mounted on the material transverse movement guide rail 3124. A material flipping mechanism 314 and a material translating mechanism 316 are both mounted on the material transverse movement base 3128, and the material transverse movement drive component 3126 is connected to the material transverse movement base 3128. The material transverse movement drive component 3126 can drive the material transverse movement base 3128 and its material flipping mechanism 314 and material translating mechanism 316 to reciprocate linearly along the material transverse movement guide rail 3124, so that the material flipping mechanism 314 reciprocates between the loading station and the first inspection station, and the material translating mechanism 316 reciprocates between the first inspection station, the second inspection station, and the unloading station. The material lateral movement drive 3126 can be configured as a cylinder drive structure or a screw and nut drive structure. When the material lateral movement drive 3126 is configured as a screw and nut drive structure, it may include a drive motor, a belt drive structure (or chain drive structure or gear drive structure) connected to the drive motor, and a screw and nut drive structure connected to the belt drive structure. The material lateral movement base 3128 may be mounted on the screw and nut drive structure.

[0045] Furthermore, the material flipping mechanism 314 may include a first material lifting structure 3142 disposed on the material transverse base 3128, a material rotation drive structure 3144 connected to the first material lifting structure 3142, and a first material gripper 3146 connected to the material rotation drive structure 3144. The first material lifting structure 3142 can drive the first material gripper 3146 to move up and down, facilitating the gripping, lowering, and translating of the flexible board by the first material gripper 3146; and the material rotation drive structure 3144 can rotate the first material gripper 3146, facilitating the flipping of the flexible board gripped by the first material gripper 3146, so that after the front side of the flexible board is inspected by the front and back visual inspection mechanism 320, the back side of the flexible board is then inspected.

[0046] Furthermore, the first material lifting structure 3142 may include a first lifting base disposed on the material transverse base 3128, a first lifting guide rail and a first lifting drive member disposed on the first lifting base, and a material rotation drive structure 3144 slidably disposed on the vertical first lifting guide rail and connected to the first lifting drive member, the first lifting drive member driving the material rotation drive structure 3144 to move up and down along the first lifting guide rail. Moreover, the material rotation drive structure 3144 may include a rotation drive base slidably disposed on the first lifting guide rail, and a rotation drive member disposed on the rotation drive base, the first material gripper 3146 being connected to the rotation drive member. The rotation drive member can drive the first material gripper 3146 to rotate, thereby flipping the flexible plate gripped by the first material gripper 3146. Furthermore, the first lifting drive member may be a cylinder drive structure, and the rotation drive member may be a motor drive structure or a rotary cylinder drive structure.

[0047] Furthermore, the material translation mechanism 316 may include a second material lifting structure 3162 disposed on the material transverse base 3128, and a second material gripper 3166 connected to the second material lifting structure 3162. The second material lifting structure 3162 can drive the second material gripper 3166 to move up and down, facilitating the gripping, lowering, and translation of the flexible board. Moreover, the second material lifting structure 3162 may include a second lifting base disposed on the material transverse base 3128, and a second lifting guide rail and a second lifting drive member disposed on the second lifting base. The second material gripper 3166 is slidably disposed on the vertical second lifting guide rail and connected to the second lifting drive member, which can drive the second material gripper 3166 to move up and down along the second lifting guide rail.

[0048] Furthermore, two first material grippers 3146 are arranged side-by-side on the material rotation drive structure 3144, and two second material grippers 3166 are arranged side-by-side on the second material lifting structure 3162. That is, in this embodiment, the material flipping mechanism 314 can simultaneously have two first material grippers 3146 gripping, moving, and flipping the flexible plate, and the material translation mechanism 316 can simultaneously have two second material grippers 3166 gripping, moving, and flipping the flexible plate. Alternatively, the material flipping mechanism 314 can include one or more first material grippers 3146 to operate on one or more flexible plates; the material translation mechanism 316 can also include one or more second material grippers 3166 to operate on one or more flexible plates. Moreover, both the first material grippers 3146 and the second material grippers 3166 can be configured as vacuum suction heads or cylinder-driven grippers.

[0049] Furthermore, the material turning and conveying mechanism 310 may also include a material longitudinal movement driving mechanism disposed on the material transverse movement driving mechanism 312 (material transverse movement base 3128). The material turning mechanism 314 and the material translation mechanism 316 may both be disposed on the material longitudinal movement driving mechanism, so that the flexible plate can be moved not only laterally but also longitudinally by the material turning and conveying mechanism 310. Moreover, the specific structure of the material longitudinal movement driving mechanism is basically similar to the specific structure of the material transverse movement driving mechanism 312, and will not be described in detail here.

[0050] In addition, such as Figure 7 and Figure 8 As shown, the front and back visual inspection mechanism 320 may include a first visual driving mechanism 322 mounted on the top frame 120, a first visual inspection frame 324 connected to the first visual driving mechanism 322, and a first appearance inspection camera 326 and a first light source system 328 mounted on the first visual inspection frame 324. The first appearance inspection camera 326 is vertically aligned with the loading platform 220. The first visual driving mechanism 322 can drive the first appearance inspection camera 326 and the first light source system 328 to move and adjust their positions so that the first appearance inspection camera 326 and the first light source system 328 are vertically aligned with the flexible board to be inspected located at the first inspection station. The first light source system 328 can illuminate the flexible board to be inspected, facilitating the first appearance inspection camera 326 to take visual inspection photos of the front and back of the flexible board to be inspected.

[0051] Specifically, the first vision driving mechanism 322 may include a first vision longitudinal shift structure 3222 disposed on the top frame 120, and a first vision lifting structure 3224 disposed on the first vision longitudinal shift structure 3222. The first vision inspection frame 324 may be disposed on the first vision lifting structure 3224, and can adjust and move the first appearance inspection camera 326 and the first light source system 328 longitudinally and vertically. In addition, the first vision driving mechanism 322 may also include a first vision transverse shift structure disposed on the first vision longitudinal shift structure 3222, and the first vision lifting structure 3224 may be disposed on the first vision transverse shift structure; or, the first vision driving mechanism 322 may also include a first vision transverse shift structure disposed on the frame 100, and the first vision longitudinal shift structure 3222 may be disposed on the first vision transverse shift structure. Moreover, the specific structures of the first visual transverse movement structure and the first visual longitudinal movement structure 3222 are similar to the specific structure of the material transverse movement drive mechanism 312 mentioned above. That is, both can be set as a cylinder drive structure or a screw nut drive structure. The specific structure of the first visual lifting structure 3224 is similar to the specific structure of the first material lifting structure 3142 and the second material lifting structure 3162 mentioned above, and will not be described again here.

[0052] In addition, such as Figure 10 and Figure 11As shown, the side visual inspection mechanism 420 may include a second visual drive mechanism 422 mounted on the top frame 120, a second visual inspection frame 424 connected to the second visual drive mechanism 422, and a second appearance inspection camera 426 and a second light source system 428 mounted on the second visual inspection frame 424. The second appearance inspection camera 426 is vertically and vertically corresponding to the rotating platform 410. After the flexible board undergoes front and back appearance inspection by the front and back visual inspection mechanism 320, it can be moved from the first inspection station to the rotating platform 410 of the second inspection station via the material transfer mechanism 310, and the appearance of the side of the flexible board is inspected by the second appearance inspection camera 426 of the side visual inspection mechanism 420. During the inspection of the side appearance of the flexible board, the positions of the second appearance inspection camera 426 and the second light source system 428 can be moved and adjusted by the second visual drive mechanism 422 to find a suitable inspection position; while the second light source system 428 can illuminate the flexible board to be inspected, facilitating the second appearance inspection camera 426 to take pictures of the side of the flexible board to be inspected.

[0053] Specifically, the second vision driving mechanism 422 may include a second vision lateral movement structure 4222 disposed on the top frame 120, and a second vision lifting structure 4224 disposed on the second vision lateral movement structure 4222. The second vision inspection frame 424 may be disposed on the second vision lifting structure 4224, and can adjust and move the second appearance inspection camera 426 and the second light source system 428 laterally and vertically. In addition, the second vision driving mechanism 422 may also include a first vision longitudinal movement structure disposed on the second vision lateral movement structure 4222, and the second vision lifting structure 4224 may be disposed on the first vision longitudinal movement structure; or, the second vision driving mechanism 422 may also include a first vision longitudinal movement structure disposed on the frame 100, and the first vision lateral movement structure 4222 may be disposed on the second vision longitudinal movement structure. Moreover, the specific structures of the second visual transverse movement structure 4222 and the second visual longitudinal movement structure are similar to the specific structure of the material transverse movement drive mechanism 312 mentioned above. That is, both can be set as a cylinder drive structure or a screw nut drive structure. The specific structure of the second visual lifting structure 4224 is similar to the specific structure of the first material lifting structure 3142 and the second material lifting structure 3162 mentioned above, and will not be described again here.

[0054] In addition, such as Figure 9As shown, the rotating stage 410 may include a rotating support 412 mounted on the base frame 110, a stage rotation drive structure 414 mounted on the rotating support 412, and a rotating platform 416 connected to the stage rotation drive structure 414. The rotating platform 416 is vertically aligned with the side visual inspection mechanism 420. The stage rotation drive structure 414 can drive the rotating platform 416 to rotate, thus rotating the flexible plate placed on the rotating platform 416. This facilitates the use of the second appearance inspection camera 426 to photograph and inspect the appearance of the flexible plate from various angles on its side. Furthermore, the stage rotation drive structure 414 may be a motor-driven structure or a rotary cylinder-driven structure.

[0055] Furthermore, in this embodiment, two rotating stages 410 can be arranged side-by-side on the base frame 110, and two second appearance inspection cameras 426 can be arranged side-by-side on the second visual inspection frame 424, corresponding one-to-one with the two rotating stages 410. That is, the side inspection unit 400 can include two second appearance inspection cameras 426 and two rotating stages 410, which can simultaneously inspect the side appearance of two flexible boards. In addition, as needed, one or more rotating stages 410 can also be provided, and one or more second appearance inspection cameras 426 can be correspondingly provided, which can photograph and inspect the side appearance of one or more flexible boards.

[0056] In addition, such as Figure 12 As shown, the unloading unit 500's unloading movement drive mechanism 510 may include a transverse unloading drive structure mounted on the base frame 110, and the unloading platform 520 is connected to the transverse unloading drive structure. The transverse unloading drive structure can drive the unloading platform 520 to reciprocate along the transverse side of the frame 100, thereby driving the unloading platform 520 to reciprocate between the unloading station and the second inspection station.

[0057] Specifically, the transverse unloading drive structure may include a transverse unloading guide rail and a transverse unloading drive component mounted on the base frame 110. The unloading platform 520 is slidably mounted on the transverse unloading guide rail, and the transverse unloading drive component is connected to the unloading platform 520. The transverse unloading guide rail extends laterally between the unloading station and the second inspection station, allowing the transverse unloading drive component to drive the unloading platform 520 to reciprocate between the unloading station and the second inspection station. The transverse unloading drive component may be a cylinder-driven structure.

[0058] In the description of this invention, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements.
