[0057] The testing device provided in this application is used to test the product 100 shown in Figures 1 and 2. The product 100 has an inner cavity 110 and a mounting hole 120 connected to the inner cavity 110. The mounting hole 120 is located on the side wall of the inner cavity 110. The inner cavity 110 of the product 100 is located inside the product 100.

[0058] As shown in FIG3 , one embodiment of the present application provides a testing apparatus 200 having a loading and unloading station 201, a first testing station 202, a transfer and flipping station 203, and a second testing station 204 arranged sequentially along a first direction. The testing apparatus 200 includes a conveying device 210, a hollow carrier 220, a rotating carrier 230, a first testing device 240, a second testing device 250, and a transfer and flipping device 260.

[0059] 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.

[0060] 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.

[0061] The first inspection device 240 and the second inspection device 250 are respectively disposed at the first inspection station 202 and the second inspection station 204. The first inspection device 240 is used to inspect the product 100 moved to the first inspection station 202, and the second inspection device 250 is used to inspect the product 100 moved to the second inspection station 204.

[0062] 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 .

[0063] 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 assumes that the first detection device 240 is a 3D detection device and the second detection device 250 is a 2D detection device.

[0064] 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 during the inspection process, the rotating carrier 230 can drive the product 100 to rotate.

[0065] It should be explained that 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 .

[0066] The specific detection process is as follows:

[0067] First, the product 100 is loaded onto the hollow carrier 220 at the loading and unloading station 201. The conveyor 210 then transports the hollow carrier 220 to the first inspection station 202, where the first inspection device 240 performs a first 3D inspection on the product 100, simultaneously inspecting both the exposed front and back sides. The conveyor 210 then transports the hollow carrier 220 to the transfer and flipping station 203. The transfer and flipping device 260 grabs the product 100 from the hollow carrier 220, removes it from the transfer and flipping station 203, and transports the rotary carrier 230 to the transfer and flipping station 203. The transfer and flipping device 260 then places the product 100 on the rotary carrier 230. The conveyor 210 then transports the rotary carrier 230 to the second inspection station 204, where the second inspection device 250 performs a first 2D inspection on the product 100. The conveying device 210 then transports the rotary carrier 230 to the transfer and flipping station 203, where the transfer and flipping device 260 flips the product 100 on the rotary carrier 230. The conveying device 210 then sequentially transports the rotary carrier 230 to the first inspection station 202 and the second inspection station 204, where the product 100 undergoes a second 3D inspection and a second 2D inspection, respectively, through the first inspection device 240 and the second inspection device 250. After the inspections are completed, the conveying device 210 first transports the rotary carrier 230 to the transfer and flipping station 203, where the transfer and flipping device 260 removes the product 100 from the rotary carrier 230. The conveying device 210 then removes the rotary carrier 230 from the transfer and flipping station 203 and transports the hollow carrier 220 to the transfer and flipping station 203. Next, the transport and flipping 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 for unloading the product 100 .

[0068] When using the above-mentioned inspection 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 inspect both the front and back sides simultaneously during 3D inspection without the need for separate inspection, that is, without the need for inspection after flipping, which effectively reduces the flipping action and improves the inspection efficiency.

[0069] Referring to Figure 4 , in one embodiment, the conveyor device 210 can also drive the hollow carrier 220 and the rotating carrier 230 to independently move in a second direction perpendicular to the first direction. It can be understood that adjusting the position of the carriers (hollow carrier 220 and rotating carrier 230) in the second direction can ensure the positioning accuracy of the carriers, thereby ensuring the accuracy of detection.

[0070] In one embodiment, the conveying device 210 includes a conveying mechanism 211, a first adjustment mechanism 212, and a second adjustment mechanism 213. The conveying mechanism 211 has two conveying ends, each connected to the first adjustment mechanism 212 and the second adjustment mechanism 213, respectively, to enable the first adjustment mechanism 212 and the second adjustment mechanism 213 to reciprocate in a first direction and move independently. The first adjustment mechanism 212 is connected to the hollow carrier 220 to enable the hollow carrier 220 to reciprocate in a second direction, and the second adjustment mechanism 213 is connected to the rotating carrier 230 to enable the rotating carrier 230 to reciprocate in the second direction.

[0071] 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 .

[0072] Optionally, the conveying mechanism 211 , the first adjusting mechanism 212 and the second adjusting mechanism 213 are all linear modules.

[0073] Please refer to 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. 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 is used to position the product 100 at the detection port 2211.

[0074] Furthermore, the positioning assembly includes a support rod 222, a pressure rod 223 and a drive module 224. The support rod 222 is arranged on one side of the substrate 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 substrate 221 to press the product 100 against the support rod 222 during the rotation process. The drive module 224 is connected to the pressure rod 223 to enable the pressure rod 223 to rotate.

[0075] 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 simultaneously detect the upper and lower sides of the product 100.

[0076] Furthermore, 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, thereby pressing the product 100 against the support rod 222, thereby vertically positioning the product 100. Furthermore, 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, eliminating the need for a driving structure in the Z direction. This allows the positioning fixture to occupy less vertical space and be used in applications where vertical space is limited.

[0077] Please refer to Figure 6. In one embodiment, the rotating carrier 230 includes a base 231, a rotating connecting seat 232, a mounting seat 233, a support assembly 234, a drive 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 support assembly 234 and the drive assembly are both arranged on the mounting seat 233. The support assembly 234 is used to support the product 100. The drive 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.

[0078] 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 .

[0079] It should be noted that the optical path adjustment component 235 includes a prism, which is used to reflect the light entering from the mounting hole 120 to the side wall of the inner cavity 110, thereby realizing detection of the side wall of the inner cavity 110.

[0080] 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.

[0081] It should be further explained that both the hollow carrier 220 and the rotating carrier 230 mentioned above further include structures for positioning the product 100 in the horizontal direction, which will not be described in detail here.

[0082] 7 , in one embodiment, the first inspection device 240 includes a first mounting frame 241 and a line scanning module. The first mounting frame 241 is disposed at the first inspection station 202 , and the line scanning module is disposed on the first mounting frame 241 for inspecting the product 100 .

[0083] Furthermore, the first detection device 240 also includes a movable module, and the line scanning module 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.

[0084] 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 in the second direction and the second movable line scan camera 245 reciprocates in the third direction.

[0085] Furthermore, 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 to enable the first movable line scan camera 244 to reciprocate along the second direction, and the second movable mechanism 243 is connected to the second movable line scan camera 245 to enable the second movable line scan camera 245 to reciprocate along the third direction.

[0086] Optionally, the first movable mechanism 242 and the second movable mechanism 243 are both linear modules.

[0087] 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 bracket 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.

[0088] 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 .

[0089] 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 upward in the third direction to relocate the hollow carrier 220. The first fixed line scan camera 246 inspects the upper surface of the product 100, while the first movable mechanism 242 drives the first movable line scan camera 244 to move in the second direction below the product 100, allowing the second movable line scan camera 245 to inspect the lower surface of the product 100.

[0090] 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 .

[0091] 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 in 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 corners of the product 100.

[0092] It is understood 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. Simultaneously, the rotating carrier 230 also drives the product 100 to rotate, allowing the first fixed line scan camera 246, the second fixed line scan camera 247, and the second movable line scan camera 245 to inspect the entire product 100.

[0093] Please refer to Figure 8. In one embodiment, the second detection device 250 includes a second mounting frame 251, a flying camera module and a fixed camera module. The second mounting frame 251 is set at the second detection station 204. The flying camera module and the fixed camera module are both set at the second mounting frame 251 to perform 2D detection on the product 100 at the second detection station 204.

[0094] Among them, the flying camera module is used to inspect the product 100 during the second 2D inspection.

[0100] 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:

[0101] Before the hollow carrier 220 moves to the first inspection station 202, the second movable mechanism 243 drives the second movable line scan camera 245 to rise in the third direction to clear the hollow carrier 220. 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, while the first movable mechanism 242 drives the first movable line scan camera 244 to move in the second direction below the product 100, allowing the second movable line scan camera 245 to inspect the lower surface of the product 100. During the inspection process, the hollow carrier 220 can be moved in the second direction, allowing the first fixed line scan camera 246 to inspect the upper surface of the product 100.

[0102] After the first 3D inspection is completed, the conveyor device 210 drives the hollow carrier 220 to the transfer and flipping station 203. The clamping module 263 grips and grabs the product 100 and then rises. The conveyor device 210 moves the hollow carrier 220 out of the transfer and flipping station 203 and moves the rotary carrier 230 to the transfer and flipping station 203. The clamping module 263 descends and places the product 100 on the rotary carrier 230. Next, the conveyor device 210 drives the rotary carrier 230 to the second inspection station 204. The second inspection device 250 performs the first 2D inspection on the product 100, specifically inspecting the product 100 using the fixed-frame module.

[0103] After the first 2D 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 descends to grab the product 100 and then rises. Then the flipping module 262 drives the clamping module 263 to rotate 180 degrees to flip the product 100. The clamping module 263 then descends and places the flipped product 100 on the rotating carrier 230. The conveying device 210 then drives the rotating carrier 230 to move to the first inspection station 202, and the flipped product 100 is subjected to a second 3D inspection by the first inspection device 240. The specific working process of the first inspection device 240 at this time is as follows:

[0104] 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 in 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 corners of the product 100.

Next, the conveying device 210 drives the rotary carrier 230 to move to the transport and flip station 203, the clamping module 263 descends to grab the product 100 and then rises, the conveying device 210 drives the rotary carrier 230 to move toward the second inspection station 204 to move out of the transport and flip station 203, and drives the hollow carrier 220 to move to the transport and flip 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 inspected product 100.
