[0036] 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.

[0037] 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.

[0038] 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 7 As shown, the first flip mechanism 220 includes a base plate 222, a translation assembly 223, a first flip seat 224 and a rotation assembly 225. The base plate 222 is fixed to the transmission end of the first transfer module 210. The translation assembly 223 is arranged on the base plate 222 and is suitable for moving along the second horizontal direction.

[0039] By adopting the above structure, the first carrier 221 is suitable for arranging the back side of the product upward under the adjustment of the first flip seat 224, so as to ensure that the back side detection camera 110 can reliably obtain the back side image of the product, and the first flip seat 224 is suitable for driving the first carrier 221 to rotate around an axis parallel to the first horizontal direction, and cooperates with the rotating component 225 to drive the first carrier 221 to rotate around an axis perpendicular to the first horizontal direction, so that the back side detection camera 110 can reliably obtain the side image of the product to meet different detection requirements.

[0040] Furthermore, the translation assembly 223 includes a translation plate 2231 and a translation cylinder 2232. A slide rail structure is supported between the translation plate 2231 and the base plate 222 so that the translation plate 2231 can slide along the second horizontal direction. The translation cylinder 2232 is a linear cylinder arranged along the second horizontal direction, which is set on the base plate 222, and the telescopic end is connected to the translation plate 2231, thereby driving the translation plate 2231 to slide relative to the base plate 222.

[0041] In this embodiment, the translation plate 2231 is a long plate, whose length direction is parallel to the first horizontal direction. There are two translation cylinders 2232, which are 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, thereby improving the stability and reliability of the translation plate 2231 during movement.

[0042] In addition, the translation assembly 223 also includes a first mounting plate 2233 fixed on the plate surface of the translation plate 2231 away from the bottom plate 222, and the number of the first mounting plates 2233 is two, and they are arranged on both sides of the translation plate 2231 in the length direction. The first flip seat 224 is connected between the two first mounting plates 2233, and the first flip seat 224 is a long strip structure with a length direction parallel to the first horizontal direction, and its two ends in the length direction can be rotatably passed through different first mounting plates 2233.

[0043] 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 .

[0044] 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.

[0045] 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.

[0046] Preferably, there are four guide rods 2245, which are respectively arranged at the four corners of the first carrier plate 2242. The first spring 2246 corresponds to the guide rod 2245 one by one to ensure stability during the floating process. Preferably, an adjusting bolt 2248 is threadedly connected to the limit block 2247, and the axial direction of the adjusting bolt 2248 is perpendicular to the plate surface of the first carrier plate 2242. The adjusting bolt 2248 is suitable for abutting against the end surface of the first carrier plate 2242 to limit the first carrier plate 2242 from separating from the guide rod 2245. By rotating the adjusting bolt 2248, it is suitable for adjusting the compression amount of the first spring 2246, and then adjusting the buffering performance to meet different needs.

[0047] Furthermore, the structure of the second flip mechanism 320 is the same as that of the first flip mechanism 220, and the present invention will not be repeated here. When the first flip mechanism 220 and the second flip mechanism 320 are both in the docking station, the first flip seat 224 of the first flip mechanism 220 and the first flip seat 224 of the second flip mechanism 320 can flip toward each other, so that the first bearing surface 2211 of the first carrier 221 and the second bearing surface (not shown) of the second carrier 321 are in a relatively arranged docking state, and the first bearing surface 2211 and the second bearing surface are perpendicular to the second horizontal direction, and then the translation assembly 223 can drive the first flip seat 224 of the first flip mechanism 220 and the second flip mechanism 320 to approach each other, so that the product on the first carrier 221 is transferred to the second carrier 321.

[0048] Further, the first carrier 221 is an adsorption type carrier, the rotating block 2252 is 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 penetrated in the avoidance hole of the rotating block 2252, the rotating shaft 2253 is provided with a vacuum channel 2254 along its axial direction, and the vacuum channel 2254 is connected to the first carrier 221 to provide adsorption force to the first carrier 221. An adsorption hole connected to the vacuum channel 2254 is provided on the first bearing surface 2211 of the first carrier 221, so that the front side of the product can be reliably adsorbed on the first bearing surface 2211. A first fixed positioning structure 2212 is provided on the first bearing surface 2211, and the first fixed positioning structure 2212 is suitable for positioning the product in the radial direction of the rotating shaft 2253. In this embodiment, the product is in a square shape, and the first fixed positioning structure 2212 is a positioning block whose outer contour matches the inner edge of the product. When the product is placed on the first carrying surface 2211, the positioning block is embedded in the inner edge of the product to achieve product positioning, specifically positioning the product in both the length direction and the width direction of the first carrier 2242. The structure of the second carrier 321 is similar to that of the first carrier 221, and it is also an adsorption carrier. The second carrier 321 is provided with a second fixed positioning structure (not shown) for positioning the product, and the present invention will not be repeated here.

[0049] The present invention sets a first fixed positioning structure 2212 on the first carrier 221 and a second fixed positioning structure on the second carrier 321, so that the position accuracy of the products placed on the first carrier 221 and the second carrier 321 is high, ensuring that the adsorption holes thereon can effectively correspond to the products, thereby improving the reliability of the products on the first carrier 221 and the second carrier 321. The use of a fixed positioning structure can make the first carrier 221 and the second carrier 321 simpler in structure and smaller in size, and adjacent carriers can be more compact, so that the detection area of ​​the back detection camera 110 and / or the front detection camera 120 covers more carriers, thereby improving the detection efficiency.

[0050] However, when a fixed positioning structure is used, when a loading robot (not shown) loads the product to the first carrier 221, the loading robot has high precision requirements, which is not conducive to reducing costs, and the loading robot needs to fine-tune the position during the loading process, which is very inefficient. The use of a movable positioning structure will lead to problems such as complex structure and increased volume.

[0051] As a preferred embodiment, refer to Figure 1 and Figure 3 As shown, the product appearance inspection equipment further includes a transfer device 400 disposed at the loading station, the transfer device 400 corresponds to the first transfer device 200, and the transfer device 400 is suitable for receiving and positioning the product to be inspected, and transferring the product to the first carrier 221. When loading, the loading robot can first load the product to the transfer device 400, and then accurately position the product through the transfer device 400 before transferring it to the first carrier 221, thereby improving the loading efficiency.

[0052] Further, refer to Figures 8 to 10 As shown, the transfer device 400 includes a second mounting frame 410, a second flip seat 420 and a third carrier 430. The second flip seat 420 is arranged on the second mounting frame 410 and can rotate around an axis parallel to the first horizontal direction. The third carrier 430 is arranged on the second flip seat 420, and there are multiple third carriers 430, which correspond to the first carrier 221 one by one.
