[0053] The detection equipment provided in this application is used to Figure 1 and Figure 2 The product 100 shown for inspection has an inner cavity 110 and a mounting hole 120 communicating with the inner cavity 110 , wherein the mounting hole 120 is located on a side wall of the inner cavity 110 . The inner cavity 110 of the product 100 is located inside the product 100 .

[0054] like Figure 3 As shown, an embodiment of the present application provides a detection device 200, which has a loading and unloading station 201, a first detection station 202, a transfer and flipping station 203 and a second detection station 204 arranged in sequence along a first direction. The detection device 200 includes a conveying device 210, a hollow carrier 220, a rotating carrier 230, a first detection device 240, a second detection device 250 and a transfer and flipping device 260.

[0055] The conveying device 210 is connected to the hollow carrier 220 and the rotating carrier 230 to drive the hollow carrier 220 and the rotating carrier 230 to move along the first direction, so that the hollow carrier 220 can move between the loading and unloading station 201 and the transport and flipping station 203, and the rotating carrier 230 can move between the first inspection station 202 and the second inspection station 204.

[0056] The hollow carrier 220 and the rotating carrier 230 are both used to carry the product 100 , and the product 100 on the hollow carrier 220 is exposed on both sides along the thickness direction. The rotating carrier 230 can rotate the product 100 around an axis parallel to the thickness direction.

[0057] The first detection device 240 and the second detection device 250 are respectively disposed at the first detection station 202 and the second detection station 204. The first detection device 240 is used to detect the product 100 moved to the first detection station 202, and the second detection device 250 is used to detect the product 100 moved to the second detection station 204.

[0058] The transport and flip device 260 is disposed at the transport and flip station 203 . The transport and flip device 260 can grab and flip the product 100 moved to the transport and flip station 203 , and place the product 100 on the rotating carrier 230 or the hollow carrier 220 moved to the transport and flip station 203 .

[0059] It should be noted that one of the first detection device 240 and the second detection device 250 is a 3D detection device, and the other is a 2D detection device. The following description is made by taking the first detection device 240 as a 3D detection device and the second detection device 250 as a 2D detection device as an example.

[0060] In order to facilitate understanding of the technical solution of the present application, the inspection items of the product 100 on the hollow carrier 220 and the rotating carrier 230 are explained here: when the product 100 is located on the hollow carrier 220, the first inspection device 240 inspects information such as the thickness and parallelism of the front and back surfaces of the product 100; when the product 100 is located on the rotating carrier 230, the first inspection device 240 inspects the edges and rounded corners of the product 100, and the second inspection device 250 inspects the inner cavity 110 and outer side features of the product 100, and the rotating carrier 230 can drive the product 100 to rotate during the inspection process.

[0061] It should be explained that when the product 100 is located on the rotating carrier 230, the second detection device 250 detects the inner cavity 110 of the product 100, which refers to the inner wall of the inner cavity 110; when the product 100 is located on the hollow carrier 220, the first detection device 240 can detect the flatness of the bottom wall of the inner cavity 110 of the product 100.

[0062] The specific detection process is as follows:

[0063] First, the product 100 is loaded onto the hollow carrier 220 of the loading and unloading station 201, and then the conveying device 210 conveys the hollow carrier 220 to the first inspection station 202, and the first inspection device 240 performs the first 3D inspection on the product 100, and can simultaneously inspect the front and back sides of the product 100 in an exposed state. Then the conveying device 210 conveys the hollow carrier 220 to the transport and flip station 203, and after the transport and flip device 260 grabs the product 100 on the hollow carrier 220, the conveying device 210 moves the hollow carrier 220 out of the transport and flip station 203, and conveys the rotating carrier 230 to the transport and flip station 203, and then the transport and flip device 260 places the product 100 on the rotating carrier 230. Next, the conveying device 210 conveys the rotating carrier 230 to the second inspection station 204, and the second inspection device 250 performs the first 2D inspection on the product 100. Then, the conveying device 210 conveys the rotating carrier 230 to the transport and flipping station 203, and the transport and flipping device 260 flips the product 100 on the rotating carrier 230. Next, the conveying device 210 conveys the rotating carrier 230 to the first inspection station 202 and the second inspection station 204 in sequence, so as to perform a second 3D inspection and a second 2D inspection on the product 100 in sequence through the first inspection device 240 and the second inspection device 250. After the inspection, the conveying device 210 first conveys the rotating carrier 230 to the transport and flipping station 203, and the transport and flipping device 260 obtains the product 100 on the rotating carrier 230. Then, the conveying device 210 moves the rotating carrier 230 out of the transport and flipping station 203, and conveys the hollow carrier 220 to the transport and flipping station 203. Next, the transport and flip device 260 places the product 100 on the hollow carrier 220 , and the conveying device 210 conveys the hollow carrier 220 to the loading and unloading station 201 to unload the product 100 .

[0064] When using the above-mentioned detection equipment 200, since both sides of the product 100 along the thickness direction are exposed when the product 100 is placed on the hollow carrier 220, it is possible to simultaneously detect the front and back sides during 3D detection without the need for separate detection, that is, without the need for flipping the product before testing, which effectively reduces the flipping action and improves the detection efficiency.

[0065] See also Figure 4 In one embodiment, the conveying device 210 can also drive the hollow carrier 220 and the rotating carrier 230 to move independently in a second direction perpendicular to the first direction. It can be understood that adjusting the position of the carrier (hollow carrier 220 and rotating carrier 230) in the second direction can ensure the positioning accuracy of the carrier, thereby ensuring the detection accuracy.

[0066] In one embodiment, the conveying device 210 includes a conveying mechanism 211, a first adjusting mechanism 212, and a second adjusting mechanism 213. The conveying mechanism 211 has two conveying ends, and the two conveying ends are respectively connected to the first adjusting mechanism 212 and the second adjusting mechanism 213, so that the first adjusting mechanism 212 and the second adjusting mechanism 213 reciprocate along the first direction and move independently. The first adjusting mechanism 212 is connected to the hollow carrier 220 so that the hollow carrier 220 reciprocates along the second direction, and the second adjusting mechanism 213 is connected to the rotating carrier 230 so that the rotating carrier 230 reciprocates along the second direction.

[0067] It is understandable that, in other embodiments, the conveying device 210 may also include two conveying mechanisms 211 , each conveying mechanism 211 has a conveying end, and the two conveying mechanisms 211 are respectively connected to the first adjustment mechanism 212 and the second adjustment mechanism 213 .

[0068] Optionally, the conveying mechanism 211 , the first adjusting mechanism 212 and the second adjusting mechanism 213 are all linear modules.

[0069] See also Figure 5 In one embodiment, the hollow carrier 220 includes a base plate 221 and a positioning assembly, the conveying device 210 is connected to the base plate 221, and the base plate 221 is provided with a detection port 2211 for accommodating the product 100 along a third direction perpendicular to the first direction and the second direction. The positioning assembly includes a support rod 222, a pressure rod 223 and a driving module 224. The support rod 222 is arranged on one side of the base plate 221 and extends into the detection port 2211 to support the product 100. The pressure rod 223 is rotatably arranged on the other side of the base plate 221 to press the product 100 against the support rod 222 during the rotation process. The driving module 224 is connected to the pressure rod 223 to rotate the pressure rod 223.

[0070] By using the above-mentioned hollow carrier 220, after the product 100 is placed on the hollow carrier 220, the thickness direction of the product 100 is parallel to the third direction, and the upper and lower sides of the product 100 are both exposed, so that the first detection device 240 can detect the upper and lower sides of the product 100 at the same time.

[0071] In addition, the product 100 is supported on the support rod 222, and then the driving module 224 drives the pressing rod 223 to rotate and press against the product 100, so as to press the product 100 against the support rod 222, thereby positioning the product 100 in the vertical direction. At the same time, since the product 100 is pressed by the rotating pressing rod 223, the driving module 224 only needs to drive the pressing rod 223 to rotate, and there is no need to set a driving structure in the Z direction, so that the positioning fixture takes up less space in the vertical direction and can be used in scenes with smaller vertical space.

[0072] See also Figure 6 In one embodiment, the rotating carrier 230 includes a base 231, a rotating connecting seat 232, a mounting seat 233, a supporting assembly 234, a driving assembly and an optical path adjustment assembly 235. The conveying device 210 is connected to the base 231. The rotating connecting seat 232 is rotatably connected to the base 231 around an axis parallel to the third direction. The mounting seat 233 is connected to the rotating connecting seat 232. The supporting assembly 234 and the driving assembly are both arranged on the mounting seat 233. The supporting assembly 234 is used to support the product 100. The driving assembly is connected to the optical path adjustment assembly 235 so that the optical path adjustment assembly 235 moves back and forth along the third direction.

[0073] When the optical path adjustment component 235 moves along the third direction, it can extend into the inner cavity 110 and face the mounting hole 120 , so that the light entering from the mounting hole 120 can be reflected to the side wall of the inner cavity 110 under the action of the optical path adjustment component 235 .

[0074] It should be noted that the optical path adjustment component 235 includes a prism, and the prism is used to reflect the light entering from the mounting hole 120 to the side wall of the inner cavity 110, so as to realize the detection of the side wall of the inner cavity 110.

[0075] At the same time, the rotating carrier 230 also includes a positioning structure for positioning the product 100 in a third direction, ie, the vertical direction, which will not be described in detail here.

[0076] It should be further explained that the aforementioned hollow carrier 220 and the rotating carrier 230 both include structures for positioning the product 100 in the horizontal direction, which will not be elaborated herein.

[0077] See also Figure 7 In one embodiment, the first detection device 240 includes a first mounting frame 241 and a line scanning module. The first mounting frame 241 is disposed at the first detection station 202, and the line scanning module is disposed at the first mounting frame 241 for detecting the product 100.

[0078] Furthermore, the first detection device 240 also includes a movable module, and the line scanning module group includes a movable line scanning module group and a fixed line scanning module group. The movable module and the fixed line scanning module group are both arranged on the first mounting frame 241. The movable module is connected to the movable line scanning module group so that the movable line scanning module group can move relative to the first mounting frame 241. The movable line scanning module group and the fixed line scanning module group are used to perform 3D detection on the product 100.

[0079] In one embodiment, the movable line scan module includes a first movable line scan camera 244 and a second movable line scan camera 245. The first movable line scan camera 244 is used to photograph the product 100 in the third direction, and the second movable line scan camera 245 is used to photograph the product 100 in the second direction. The movable module is connected to the first movable line scan camera 244 and the second movable line scan camera 245, so that the first movable line scan camera 244 reciprocates along the second direction, and the second movable line scan camera 245 reciprocates along the third direction.

[0080] Further, the movable module includes a first movable mechanism 242 and a second movable mechanism 243. The first movable mechanism 242 is connected to the first movable line scan camera 244 so that the first movable line scan camera 244 reciprocates along the second direction, and the second movable mechanism 243 is connected to the second movable line scan camera 245 so that the second movable line scan camera 245 reciprocates along the third direction.

[0081] Optionally, the first movable mechanism 242 and the second movable mechanism 243 are both linear modules.

[0082] In one embodiment, the fixed line scan module includes a first fixed line scan camera 246 and a second fixed line scan camera 247 arranged on a first mounting frame 241. The first fixed line scan camera 246 is used to photograph the product 100 in a third direction, and the second fixed line scan camera 247 is used to photograph the product 100 in a direction inclined relative to the third direction, that is, to photograph the product 100 in a direction inclined relative to the vertical direction and the horizontal direction.

[0083] It should be noted that both the first movable line scan camera 244 and the first fixed line scan camera 246 photograph the product 100 in the third direction, and the first movable line scan camera 244 is located below the first fixed line scan camera 246 .

[0084] When inspecting the upper and lower sides of the product 100 on the hollow carrier 220, the second movable mechanism 243 drives the second movable line scan camera 245 to rise along the third direction to avoid the hollow carrier 220. The first fixed line scan camera 246 inspects the upper surface of the product 100, and the first movable mechanism 242 drives the first movable line scan camera 244 to move to the bottom of the product 100 along the second direction, so that the second movable line scan camera 245 inspects the lower surface of the product 100.

[0085] It is understandable that during the inspection process, since the first fixed line scan camera 246 is fixed, the hollow carrier 220 can be moved along the second direction so that the first fixed line scan camera 246 can inspect the upper surface of the product 100 .

[0086] When inspecting the product 100 on the rotating carrier 230, the first movable mechanism 242 drives the first movable line scan camera 244 to move along the second direction to avoid the rotating carrier 230. The first fixed line scan camera 246, the second fixed line scan camera 247 and the second movable line scan camera 245 inspect the edges and rounded corners of the product 100.

[0087] It is understandable that during the inspection process of the second movable line scan camera 245, the second movable mechanism 243 drives the second movable line scan camera 245 to move along the third direction. At the same time, the rotating carrier 230 also drives the product 100 to rotate, so that the first fixed line scan camera 246, the second fixed line scan camera 247 and the second movable line scan camera 245 inspect the entire product 100.

[0088] See also Figure 8 In one embodiment, the second detection device 250 includes a second mounting frame 251, a flying module and a fixed module. The second mounting frame 251 is arranged at the second detection station 204. The flying module and the fixed module are both arranged at the second mounting frame 251 to perform 2D detection on the product 100 at the second detection station 204.

[0089] Among them, the flying camera module is used to inspect the product 100 during the second 2D inspection. At this time, the inner cavity 110 of the product 100 faces downward, and the flying camera module cooperates with the rotating carrier 230 to inspect the inner and outer side features of the product 100; the fixed camera module is used to inspect the product 100 during the first 2D inspection. At this time, the inner cavity 110 of the product 100 faces upward, and the fixed camera module cooperates with the rotating carrier 230 to inspect the features of the outer side and inner cavity 110 of the product 100.

[0095] First, the hollow carrier 220 at the loading and unloading station 201 is loaded with the product 100, and then the conveying device 210 drives the hollow carrier 220 to move to the first inspection station 202, and the first inspection device 240 performs the first 3D inspection on the product 100. The specific working process of the first inspection device 240 is as follows:

After the hollow carrier 220 moves to the first inspection station 202, the first fixed line scan camera 246 inspects the upper surface of the product 100, and the first movable mechanism 242 drives the first movable line scan camera 244 to move below the product 100 along the second direction, so that the second movable line scan camera 245 inspects the lower surface of the product 100. During the inspection process, the hollow carrier 220 can be moved along the second direction so that the first fixed line scan camera 246 inspects the upper surface of the product 100.

[0097] After the first 3D inspection is completed, the conveying device 210 drives the hollow carrier 220 to move to the transport and flipping station 203, the clamping module 263 clamps and grabs the product 100 and then rises, the conveying device 210 moves the hollow carrier 220 out of the transport and flipping station 203, and moves the rotating carrier 230 to the transport and flipping station 203, the clamping module 263 descends and places the product 100 on the rotating carrier 230. Next, the conveying device 210 drives the rotating carrier 230 to move to the second inspection station 204, and the first 2D inspection of the product 100 is performed by the second inspection device 250, and specifically, the product 100 is inspected by the fixed shooting module.

[0098] After the first 2D inspection is completed, the conveying device 210 drives the hollow carrier 220 to move to the handling and flipping station 203, the clamping module 263 descends to grab the product 100 and then rises, and then the flipping module 262 drives the clamping module 263 to rotate 180° to flip the product 100.

Then the conveying device 210 drives the rotating carrier 230 to move to the first inspection station 202, and the first inspection device 240 performs a second 3D inspection on the flipped product 100. At this time, the specific working process of the first inspection device 240 is as follows:

[0099] Before the rotating carrier 230 moves to the first inspection station 202, the first movable mechanism 242 drives the first movable line scan camera 244 to move along the second direction to avoid the rotating carrier 230. After the rotating carrier 230 moves to the first inspection station 202, the first fixed line scan camera 246, the second fixed line scan camera 247 and the second movable line scan camera 245 inspect the edges and rounded corners of the product 100.

Next, the conveying device 210 drives the rotating carrier 230 to move to the handling and flipping station 203, the clamping module 263 descends to grab the product 100 and then rises, the conveying device 210 drives the rotating carrier 230 to move toward the second inspection station 204 to move out of the handling and flipping station 203, and drives the hollow carrier 220 to move to the handling and flipping station 203. Then the clamping module 263 descends to place the product 100 on the hollow carrier 220, and the conveying device 210 drives the hollow carrier 220 to move to the loading and unloading station 201 to unload the product 100 that has been inspected.
