Description

Technical Field

[0001] The present invention relates to the technical field of appearance detection, and particularly relates to a product appearance detection device. Background Art

[0002] For some injection-molded products, it is necessary to detect the appearance of the front and back sides after production to ensure their qualified ex-factory. For example, Chinese Utility Model Patent CN202420169717.8 discloses an appearance detection device, including a loading and transferring mechanism, an unloading and transferring mechanism, and a camera detection mechanism. During operation, the workpiece to be detected is placed on the loading and transferring mechanism, and the loading and transferring mechanism moves the workpiece to be detected below the camera detection mechanism for front-side detection. After the front-side detection of the workpiece is completed, the loading and transferring mechanism and the unloading and transferring mechanism face each other in the forward direction to transfer the workpiece on the loading and transferring mechanism to the unloading and transferring mechanism, and the unloading and transferring mechanism moves the workpiece to below the camera detection mechanism for back-side detection.

[0003] However, with the above structure, the number of workpieces to be detected received by the detection device each time is small, it is difficult to achieve high-efficiency detection operations for large quantities, and the cameras of the camera detection mechanism need to correspond to the workpieces one by one. As the number of workpieces increases, the number of cameras also increases, which is not conducive to cost reduction.

[0058] Please refer to Figures 1 to 3As shown in the figure, a product appearance detection device corresponding to a preferred embodiment of the present invention includes: a detection device 100, including a reverse detection camera 110 and a front detection camera 120; a first transfer device 200, including a first transfer module 210 and a first flipping mechanism 220 provided on the first transfer module 210. The first flipping mechanism 220 includes a plurality of first carriers 221. The product is adapted to be placed on the first carrier 221, and the reverse side faces away from the first carrier 221; a second transfer device 300, including a second transfer module 310 and a second flipping mechanism 320 provided on the second transfer module 310. The second flipping mechanism 320 includes a plurality of second carriers 321. The product is adapted to be placed on the second carrier 321, and the front side faces away from the second carrier 321; wherein, the first transfer module 210 is adapted to drive the first flipping mechanism 220 to move from the loading station to the docking station, and make the first carriers 221 flow through the reverse detection camera 110 in sequence. The second transfer module 310 is adapted to drive the second flipping mechanism 320 to move from the docking station to the unloading station, and make the second carriers 321 flow through the front detection camera 120 in sequence. And when the first flipping mechanism 220 and the second flipping mechanism 320 are both in the docking station, the first flipping mechanism 220 and the second flipping mechanism 320 are adapted to be docked with each other to transfer the product on the first carrier 221 to the second carrier 321.

[0059] With the above structure adopted in the present invention, the first flipping mechanism 220 is adapted to move back and forth between the loading station and the docking station driven by the first transfer module 210, and the second flipping mechanism 320 is adapted to move back and forth between the unloading station and the docking station driven by the second transfer module 310, so as to load the product to be detected onto the first carrier 221 of the first flipping mechanism 220 and unload the detected product from the second carrier 321 of the second flipping mechanism 320; when the first flipping mechanism 220 moves from the loading station to the docking station, several first carriers 221 flow through the reverse detection camera 110 in sequence, so that a single reverse detection camera 110 can detect the products on multiple first carriers 221. When the second flipping mechanism 320 moves from the docking station to the unloading station, several second carriers 321 flow through the front detection camera 120 in sequence, so that a single front detection camera 120 can detect the products on multiple second carriers 321, avoiding adding a large number of cameras, effectively reducing costs, and enabling high-efficiency detection operations for a large number of products.

[0060] Further, the detection device 100 includes a first mounting frame 130 and a third transfer module 140 disposed on the first mounting frame 130. There are multiple third transfer modules 140, and they correspond to the back detection camera 110 and the front detection camera 120 one by one. The back detection camera 110 and / or the front detection camera 120 are installed on the third transfer module 140 and are located above the first carrier 221 and the second carrier 321. The shooting ends of the back detection camera 110 and the front detection camera 120 are arranged downward, and the third transfer module 140 is suitable for driving the back detection camera 110 and / or the front detection camera 120 to move along the second horizontal direction and the vertical direction. By adopting the above structure, the back detection camera 110 and / or the front detection camera 120 can adjust the position along the second horizontal direction and the vertical direction under the drive of the third transfer module 140 to achieve the best focusing effect while ensuring that it can reliably obtain the image information of the product, thereby improving the versatility and the detection effect.

[0061] Further, the transfer directions of the first transfer module 210 and the second transfer module 310 are parallel to the first horizontal direction, and the plurality of first carriers 221 and second carriers 321 are arranged side by side along the first horizontal direction. The first carrier 221 is suitable for sequentially passing directly under the back detection camera 110 driven by the first transfer module 210, so that the back detection camera 110 can take pictures of the products on the first carrier 221, and the second carrier 321 is suitable for sequentially passing directly under the front detection camera 120 driven by the second transfer module 310, so that the front detection camera 120 can take pictures of the products on the second carrier 321. When the first flip mechanism 220 and the second flip mechanism 320 are in the docking station, the first flip mechanism 220 and the second flip mechanism 320 are arranged side by side in the second horizontal direction perpendicular to the first horizontal direction to ensure that the first flip mechanism 220 and the second flip mechanism 320 can be docked smoothly.

[0062] Preferably, in this embodiment, there are multiple first transfer devices 200, which are arranged side by side along the second horizontal direction, there are multiple second transfer devices 300, which are arranged side by side along the second horizontal direction, the first transfer devices 200 and the second transfer devices 300 correspond one to one, the back detection camera 110 corresponds one to one to the first transfer device 200, and the front detection camera 120 corresponds one to one to the second transfer device 300. By adopting the above structure, more products can be detected at the same time during the operation of the detection equipment, further improving the detection efficiency.

[0063] Furthermore, the first transfer module 210 and the second transfer module 310 are both conventional linear modules, and the present invention will not be described in detail herein. Figures 4 to 7As shown in the figure, the first flipping mechanism 220 includes a bottom plate 222, a translation assembly 223, a first flipping seat 224, and a rotation assembly 225. The bottom plate 222 is fixed to the driving end of the first transfer module 210. The translation assembly 223 is disposed on the bottom plate 222 and is adapted to move along the second horizontal direction. The first flipping seat 224 is disposed on the translation assembly 223 and can rotate about an axis parallel to the first horizontal direction. The translation assembly 223 is adapted to drive the first flipping seat 224 to move synchronously along the second horizontal direction. The rotation assembly 225 is disposed on the first flipping seat 224 and is adapted to rotate about an axis perpendicular to the first horizontal direction. There are multiple rotation assemblies 225, and the first carriers 221 are respectively disposed on different rotation assemblies 225.

[0064] By adopting the above structure, the first carrier 221 is adapted to arrange the reverse side of the product facing upwards under the adjustment of the first flipping seat 224 to ensure that the reverse side detection camera 110 can reliably obtain the reverse side image of the product. And the first flipping seat 224 is adapted to drive the first carrier 221 to rotate about an axis parallel to the first horizontal direction, and cooperate with the rotation assembly 225 to drive the first carrier 221 to rotate about an axis perpendicular to the first horizontal direction, so that the reverse side detection camera 110 can reliably obtain the side image of the product to meet different detection requirements.

[0065] Further, the translation assembly 223 includes a translation plate 2231 and a translation cylinder 2232. A slide rail structure is provided between the translation plate 2231 and the bottom plate 222 to enable the translation plate 2231 to slide along the second horizontal direction. The translation cylinder 2232 is a linear cylinder arranged along the second horizontal direction. It is disposed on the bottom plate 222, and its telescopic end is connected to the translation plate 2231, thereby driving the translation plate 2231 to slide relative to the bottom plate 222.

[0066] In this embodiment, the translation plate 2231 is a long strip plate body, and its length direction is parallel to the first horizontal direction. The number of translation cylinders 2232 is two, and they are respectively arranged on both sides of the translation plate 2231 in the length direction. The two translation cylinders 2232 cooperate to drive the translation plate 2231, improving the stability and reliability of the translation plate 2231 during movement.

[0067] In addition, the translation assembly 223 further includes two first mounting plates 2233 fixed to the surface of the translation plate 2231 facing away from the bottom plate 222, and they are respectively arranged on both sides of the translation plate 2231 in the length direction. The first flipping seat 224 is connected between the two first mounting plates 2233. The first flipping seat 224 is a long strip structure with its length direction parallel to the first horizontal direction, and the two ends in its length direction are rotatably passed through different first mounting plates 2233.

[0068] The first flip seat 224 includes a first seat body 2241, a first carrier plate 2242, a first floating assembly and a first flip motor 2243. Both ends of the first seat body 2241 are provided with shaft bodies 2244. The two shaft bodies 2244 are rotatably arranged on different first mounting plates 2233, respectively, and the axial direction of the shaft bodies 2244 is parallel to the first horizontal direction. The first flip motor 2243 is arranged on the translation plate 2231, and its output end is transmission-connected with the first seat body 2241 to drive the first seat body 2241 to rotate. The first floating assembly is supported between one of the plate surfaces of the first carrier plate 2242 and the first seat body 2241. The first floating assembly is suitable for driving the first carrier plate 2242 to float in a direction perpendicular to its plate surface. The plate surface of the first carrier plate 2242 specifically refers to the end surface perpendicular to its thickness direction. The rotating assembly 225 is installed on the first carrier plate 2242. The length direction of the first carrier plate 2242 is parallel to the first horizontal direction. The rotating assembly 225 is arranged side by side and spaced along the length direction of the first carrier plate 2242, and the rotation axis is perpendicular to the plate surface of the first carrier plate 2242. The rotating assembly 225 includes a rotating motor 2251 and a rotating block 2252. The rotating motor 2251 is fixed to the first carrier plate 2242, and its output end extends out of the plate surface of the first carrier plate 2242 away from the first floating assembly. The rotating block 2252 is fixed to the output end of the rotating motor 2251, and the first carrier 221 is fixed to the rotating block 2252. The bearing direction of the first carrier 221 is perpendicular to the plate surface of the first carrier plate 2242, and the front of the product is carried on the first carrier 221. The first carrier 221 has a first carrying surface 2211 for carrying products. The first carrying surface 2211 is parallel to the surface of the first carrier plate 2242 . The carrying direction of the first carrier 221 is specifically a direction perpendicular to the first carrying surface 2211 .

[0069] By adopting the above structure, when the first carrier 221 and the second carrier 321 are docked, the first floating assembly is suitable for buffering the first carrier 221 and the second carrier 321 to protect the first carrier 221, the second carrier 321 and the product, and enable the product to be transferred more reliably.

[0070] Specifically, the first floating assembly includes a guide rod 2245, a first spring 2246 and a limit block 2247. The axial direction of the guide rod 2245 is perpendicular to the plate surface of the first carrier plate 2242. One end of the guide rod 2245 is fixed to the first seat body 2241. The first carrier plate 2242 is slidably mounted outside the guide rod 2245. The first spring 2246 is mounted outside the guide rod 2245, and both ends are supported between the first carrier plate 2242 and the first seat body 2241. The limit block 2247 is arranged on the first seat body 2241 and is suitable for limiting the first carrier plate 2242 from being separated from the guide rod 2245 from the other end of the guide rod 2245. The first spring 2246 is suitable for pushing the first carrier plate 2242 to the limit block 2247.

[0071] Preferably, the number of guide rods 2245 is four, and they are respectively arranged at the four corners of the first carrier plate 2242. The first springs 2246 correspond to the guide rods 2245 one by one to ensure the stability during the floating process. Preferably, an adjusting bolt 2248 is threadedly connected to the limiting block 2247. The axial direction of the adjusting bolt 2248 is perpendicular to the plate surface of the first carrier plate 2242, and the adjusting bolt 2248 is adapted to abut against the end surface of the first carrier plate 2242 to prevent the first carrier plate 2242 from detaching from the guide rod 2245. By rotating the adjusting bolt 2248, it is adapted to adjust the compression amount of the first spring 2246, thereby adjusting the buffering performance to meet different requirements.

[0072] Furthermore, the structure of the second flipping mechanism 320 is the same as that of the first flipping mechanism 220, and thus will not be described in detail herein. When both the first flipping mechanism 220 and the second flipping mechanism 320 are in the docking station, the first flipping seats 224 of the first flipping mechanism 220 and the second flipping mechanism 320 can flip towards each other, so that the first bearing surface 2211 of the first carrier 221 and the second bearing surface (not shown in the figure) of the second carrier 321 are in a relatively arranged docking state. The first bearing surface 2211 and the second bearing surface are perpendicular to the second horizontal direction. Then, the translation assembly 223 can drive the first flipping seats 224 of the first flipping mechanism 220 and the second flipping mechanism 320 to approach each other, so that the product on the first carrier 221 is transferred to the second carrier 321.

[0073] Furthermore, the first carrier 221 is an adsorption-type carrier. The rotating block 2252 is axially provided with an avoidance hole along the axial direction of the rotating motor 2251. The rotating shaft 2253 of the rotating motor 2251 is fixedly inserted into the avoidance hole of the rotating block 2252. The rotating shaft 2253 is axially provided with a vacuum channel 2254, and the vacuum channel 2254 is communicated with the first carrier 221 to provide an adsorption force to the first carrier 221. Adsorption holes communicated with the vacuum channel 2254 are formed on the first bearing surface 2211 of the first carrier 221, so that the front surface of the product can be reliably adsorbed on the first bearing surface 2211. A first fixed positioning structure 2212 is arranged on the first bearing surface 2211, and the first fixed positioning structure 2212 is adapted to position the product in the radial direction of the rotating shaft 2253. In this embodiment, the product has a square structure with a hole in the middle. The first fixed positioning structure 2212 is a positioning block whose outer contour is adapted to the inner edge of the product. After the product is placed on the first bearing surface 2211, the positioning block is embedded in the inner edge of the product to realize the positioning of the product, specifically positioning the product in both the length direction and the width direction of the first carrier plate 2242. The structure of the second carrier 321 is similar to that of the first carrier 221, and it is also an adsorption-type carrier. A second fixed positioning structure (not shown in the figure) for positioning the product is arranged on the second carrier 321, and thus will not be described in detail herein.

[0074] In the present invention, by providing a first fixed positioning structure 2212 on the first carrier 221 and a second fixed positioning structure on the second carrier 321, the positional accuracy of the product placed on the first carrier 221 and the second carrier 321 is high, ensuring that the adsorption holes thereon can effectively correspond to the product, improving the reliability of the product on the first carrier 221 and the second carrier 321, and adopting a fixed positioning structure enables the structures of the first carrier 221 and the second carrier 321 to be simpler and smaller in volume, and enables the adjacent carriers to be more compact, so that the detection areas of the back detection camera 110 and / or the front detection camera 120 cover more carriers, improving the detection efficiency.

[0075] However, when adopting a fixed positioning structure, when the loading manipulator (not shown in the figure) loads the product onto the first carrier 221, the accuracy requirement for the loading manipulator is relatively high, which is not conducive to cost reduction, and the position of the loading manipulator needs to be finely adjusted during the loading process, resulting in very low efficiency. While adopting a movable positioning structure will lead to problems of complex structure and increased volume.

[0076] As a preferred embodiment, referring to Figure 1 and Figure 3 as shown, the product appearance detection device further includes a transfer device 400 arranged at the loading station. The transfer device 400 corresponds to the first transfer device 200 one by one. The transfer device 400 is adapted to receive and position the product to be detected and transfer the product to the first carrier 221. During loading, the loading manipulator can first load the product onto the transfer device 400, and then accurately position the product through the transfer device 400 and then transfer it to the first carrier 221, thereby improving the loading efficiency.

[0077] Furthermore, referring to Figures 8 to 10 as shown, the transfer device 400 includes a second mounting frame 410, a second flipping seat 420 and a third carrier 430.

[0078] The present invention adopts the above-mentioned structure, and the third carrier 430 positions the product through the movable positioning structure cooperating with the third fixed positioning structure 431. When the loading robot loads the product to the third carrier 430, the position accuracy requirement of the product is relatively low, which is convenient for the loading robot to load the product efficiently. After the product is placed on the third carrier 430, the movable positioning structure can be reliably moved toward the third fixed positioning structure 431 to achieve precise positioning of the product.

[0079] Furthermore, the second mounting frame 410 includes two second mounting plates 411 arranged relatively along the first horizontal direction, and the second flip seat 420 is rotatably connected between the two second mounting plates 411.

At this time, the plate surface of the second carrier plate 422 is perpendicular to the vertical direction, and the third carrier 430 is arranged upward; the loading manipulator loads the product onto different third carriers 430, and then the movable positioning structure pushes the product against the third fixed positioning structure 431 to achieve precise positioning of the product; then the transfer device 400 rotates to the docking state. The plate surface of the second carrier plate 422 is perpendicular to the second horizontal direction, and the third carrier 430 faces the corresponding first transfer device 200. At the same time, the first transfer module 210 drives the first flipping mechanism 220 to move to the loading station. The first flipping mechanism 220 rotates to the docking state so that the plate surface of the first carrier plate 2242 is perpendicular to the second horizontal direction, and the first carrier 221 faces the transfer device 400; then the translation assembly 223 drives the first flipping mechanism 220 to approach the third carrier 430 along the second horizontal direction so that the product on the third carrier 430 is transferred to the first carrier 221; then the translation assembly 223 resets, and the first transfer module 210 drives the first flipping mechanism 220 to move to the docking station. During this process, the reverse detection camera 110 can perform appearance detection on the product. At the same time, the second transfer module 310 drives the second flipping mechanism 320 to move to the docking station; when both the first flipping mechanism 220 and the second flipping mechanism 320 are in the docking station, both turn to the docking state and, driven by the translation assembly 223, the product on the first carrier 221 is transferred to the second carrier 321; then the second transfer module 310 drives the second flipping mechanism 320 to move to the unloading station. During this process, the front detection camera 120 can perform appearance detection on the product and perform unloading; repeat the above actions to achieve continuous detection of the product.
