[0022] Currently, many parts inspection and installation devices have some shortcomings in practical applications. On the one hand, some devices are not perfect in the inspection process before parts installation, and cannot comprehensively and accurately inspect the quality of parts, resulting in some defective parts being installed on the workpiece, affecting the performance and reliability of the final product.

[0023] To address the problem of the inability to comprehensively and accurately inspect the quality of parts, this utility model provides a parts inspection and installation device, which includes: The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 5 This utility model provides a parts inspection and installation device, including: Base 100; The material tray 110 is disposed on one side of the machine base 100, and the workpiece is placed on the other side of the machine base 100. The material tray 110 is used to place the parts. The gripping module 200 is mounted on the base 100. The gripping module 200 is used to grip the part onto the workpiece and install the part onto the workpiece. The first camera module 310 is mounted on the gripping module 200. The first camera module 310 is used to photograph the parts for inspection. The first supplementary lighting module 410 is disposed on the gripping module 200. The first supplementary lighting module 410 includes a ring light 411 and a filter 412. The first supplementary lighting module 410 is used to illuminate the part. The middle part of the ring light 411, the filter 412 and the first camera module 310 are arranged in sequence, and the part is located directly below the ring light 411. The control module 500, the grasping module 200, the first camera module 310 and the first supplementary lighting module 410 are electrically connected to the control module 500.

[0025] Based on this, by setting a first camera module 310 on the gripping module 200, the first camera module 310 captures images of the surface of the part during the process of the gripping module 200 gripping the part to the workpiece. Image recognition is then performed on the captured images of the part surface to determine whether there are defects on the part surface. However, when the ambient light of the part detection and installation device is low, the part surface images captured by the first camera module 310 are generally dark, which is not conducive to image recognition. Therefore, by simultaneously setting a first supplementary lighting module 410 on the gripping module 200, the first supplementary lighting module... Block 410 includes a ring light 411 and a filter 412. The component is positioned directly below the center of the ring light 411, allowing the ring light 411 to illuminate the entire surface of the component, reducing local dimness caused by the irregular surface of the component blocking the light. By placing the filter 412 between the ring light 411 and the first camera module 310, the filter 412 can weaken the local strong light incident from below into the first camera module 310, improving the quality of the component surface image, making the component surface image clearer, and improving the accuracy of image detection of the component surface image.

[0026] In one specific implementation, after the first camera module 310 captures an image of the part surface, the first camera module 310 sends the part surface image to the control module 500. The control module 500 has a pre-trained image defect detection model built in. The control module 500 calls the image defect detection model to identify defects in the part surface image, thereby identifying whether there are defects on the part surface.

[0027] The base 100 is also equipped with a scrap box (not shown in the figure). When the control module 500 determines that the surface of the part is intact, the control module 500 controls the gripping module 200 to install the part onto the workpiece. When the control module 500 determines that there is a defect on the surface of the part, the control module 500 controls the gripping module 200 to place the part into the scrap box.

[0028] In one specific embodiment, the mirror surface of the first camera module 310 can be divided into two parts. When the gripping module 200 grips the part, the part is located below one part of the mirror surface. When the gripping module 200 moves the part to the workpiece, the gripping module 200 first moves the part a certain distance so that the part is not directly above the mounting part on the workpiece, but the other part of the mirror surface is directly above the mounting part on the workpiece. The first camera module 310 takes a picture of the workpiece surface, and the resulting second image includes the surface of the part and the mounting part on the workpiece. The control module 500 calls the defect image recognition model again to identify defects in the mounting part of the workpiece. When there are no defects in the mounting part of the workpiece, the control module 500 controls the gripping module 200 to retract a certain distance so that the part is directly above the mounting part, and then installs the part onto the workpiece. When there are defects in the mounting part of the workpiece, the control module 500 controls the replacement of the workpiece and takes another picture of the mounting part of the workpiece for inspection.

[0029] Additionally, refer to Figure 3 As shown, in some embodiments of this utility model, a second supplementary lighting module 420 is also included. The second supplementary lighting module 420 is disposed on the base 100 and is electrically connected to the control module 500. The second supplementary lighting module 420 is used to illuminate the parts.

[0030] The second supplementary lighting module 420 is different from the first supplementary lighting module 410. The second supplementary lighting module 420 is mounted on the base 100. The first supplementary lighting module 410 illuminates the part from the upper surface of the part, while the second supplementary lighting module 420 illuminates the part from the lower surface of the part.

[0031] The second supplementary lighting module 420 includes a light 421 and a one-way mirror 422. The one-way mirror 422 is located directly below the part. The part, the one-way mirror 422, and the second camera module 320 are arranged in sequence. The reflective surface of the one-way mirror 422 is close to the part, and the observation surface of the one-way mirror 422 is away from the part. That is, the reflective surface of the one-way mirror 422 faces upward and the observation surface faces downward. As in the previous embodiment, the mirror surface of the first camera module 310 can be divided into two parts. The part is located below one part of the mirror surface. When the grasping module 200 moves the part above the one-way mirror 422, the other part of the mirror surface of the first camera module 310 can receive the bottom image of the part reflected by the one-way mirror 422. Therefore, the control module 500 can simultaneously detect the images of the front of the part and the ground.

[0032] After the gripping module 200 grips the part from the loading tray 110, it first moves the part directly above the lighting lamp 421 and the one-way perspective mirror. With the cooperation of the first supplementary lighting module 410 and the second supplementary lighting module 420, the first camera module 310 takes a picture of the part. Then, the gripping module 200 moves the first camera module 310 directly above the mounting part on the workpiece, and the first camera module 310 takes a picture of the mounting part on the workpiece. Then, the gripping module 200 moves the part directly above the mounting part on the workpiece and mounts the part onto the workpiece.

[0033] In some specific embodiments, the lighting lamp 421 may also be a ring structure like the ring lamp 411, with the component located above the center of the lighting lamp 421. This utility model will not impose any restrictions.

[0034] In addition, in some embodiments of this utility model, the part inspection and installation device may also be provided with a second camera module 320. The second camera module 320 is disposed in the base 100 and is electrically connected to the control module 500. The second camera module 320 and the first camera module 310 respectively photograph both sides of the part.

[0035] Specifically, the second camera module 320 is positioned below the observation surface of the one-way mirror. The light illuminating the surface of the part by the lamp 421 is transmitted through the one-way mirror 422 to the second camera module 320. The second camera module 320 captures an image of the bottom surface of the part, and the control module 500 identifies the image of the bottom surface of the part to determine whether there are any defects on the bottom surface of the part.

[0036] In addition, in some embodiments of this utility model, the part inspection and installation device may also be provided with a third camera module 330. The third camera module 330 is disposed on the gripping module 200 and electrically connected to the control module 500. The third camera module 330 is used to photograph the workpiece for inspection.

[0037] When the gripping module 200 is equipped with a third camera module 330 and the base 100 is equipped with a second camera module 320, the first camera module 310 can be positioned directly above the part, that is, the part is projected onto the center of the mirror surface of the first camera module 310. The first camera module 310 is used to photograph the upper surface of the part, the second camera module 320 is used to photograph the lower surface of the part, and the third camera module 330 is used to photograph the workpiece.

[0038] When the control module 500 determines that the surface of the part is intact through the defect image recognition module, the control module 500 controls the gripping module 200 to move the third camera module 330 directly above the mounting part on the workpiece, and the third camera module 330 takes a picture of the surface of the workpiece. When the control module 500 determines that the surface of the workpiece is intact, the control module 500 controls the gripping module 200 to move the part directly above the mounting part on the workpiece and install the part on the workpiece.

[0039] In some embodiments of this utility model, the gripping module 200 includes a fixed base 210 and a horizontal rotating arm 220. The fixed base 210 is fixed on the base 100, and the fixed end of the horizontal rotating arm 220 is disposed on the fixed base 210. The horizontal rotating arm 220 is used to provide movement in the horizontal direction.

[0040] In addition, the gripping module 200 also includes a vertical drop arm 230. The fixed end of the vertical drop arm 230 is disposed on the movable end of the horizontal rotating arm 220. The vertical drop arm 230 is used to provide vertical movement, and the movable end of the vertical drop arm 230 is used to grip parts.

[0041] Specifically, directly above the base 100, from a vertically downward perspective, the horizontal rotating arm 220 rotates clockwise, causing the vertical drop arm 230 to reach directly above the loading tray 110. The vertical drop arm 230 releases its movable end to the loading tray 110. After the vertical drop arm 230 picks up the part, it retracts its movable end, and the horizontal rotating arm 220 rotates counterclockwise, causing the vertical drop arm 230 to reach directly above the second supplementary lighting module 420. The first camera module 310 and the second camera module 320 respectively capture images of the upper and lower surfaces of the part. When the control module 500 determines that there is a defect on the surface of the part, the horizontal rotating arm 220 rotates, rotating the vertical drop arm 230 to the waste bin. Directly above the workpiece, the vertical drop arm 230 releases the part into the waste bin, and then performs the next gripping. When the control module 500 determines that the part is intact, the horizontal rotating arm 220 continues to rotate counterclockwise, rotating the vertical drop arm 230 above the workpiece. The first camera module 310 or the third camera module 330 is located directly above the installation position and takes pictures of the workpiece. When the control module 500 determines that the workpiece surface is normal, the horizontal rotating arm 220 rotates slightly clockwise, so that the movable end of the vertical drop arm 230 is directly above the installation position. The movable end of the vertical drop arm 230 moves downward, thereby installing the part onto the workpiece.

[0042] In addition, in some embodiments of this utility model, the parts inspection and installation device also includes a conveyor belt 600, which is disposed on one side of the base 100. The conveyor belt 600 is electrically connected to the control module 500 and is used to transport workpieces one by one.

[0043] The workpiece is placed on the conveyor belt 600, which transports the workpieces one by one to a specific position so that the gripping module 200 can install the parts onto the workpiece.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
