[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] like Figure 1 As shown, the utility model provides a shell appearance inspection device, which is used to detect the appearance defects of the shell workpiece 500, and the appearance defects include the shape, size and appearance defects of the shell workpiece 500. The shell workpiece 500 is formed with a concave cavity, and an edge ring portion 510 is provided around the cavity opening of the concave cavity. The shell appearance inspection device includes: a base 100, a stage assembly 200, and a visual assembly 300. The base 100 is used to carry the stage assembly 200 and the visual assembly 300. The stage assembly 200 is arranged on the base 100, and is used to support the shell workpiece 500. The visual assembly 300 is arranged on the base 100, and is located above the stage assembly 200, and is used to collect image information of the shell workpiece 500.

[0032] The stage assembly 200 is located in the center of the base 100, so that the base 100 forms pedestrian passages located on both sides of the stage assembly 200, and the operator can easily approach the stage assembly 200 to check the placement of the shell workpiece 500, which is also convenient for maintenance.

[0033] like Figure 2 and Figure 3As shown, the stage assembly 200 includes a bottom plate 210 disposed on the base 100, a plurality of first support seats 220 and a plurality of second support seats 230 disposed on the bottom plate 210, the heights of the plurality of first support seats 220 are fixed, and the heights of the plurality of second support seats 230 are adjustable. The plurality of first support seats 220 are arranged to form a first area, and the plurality of second support seats 230 are located in the first area or outside the first area.

[0034] like Figures 4 to 6 As shown, the first support seat 220 includes a first carrier block 223 located at the top thereof and detachably arranged, and the second support seat 230 includes a second carrier block 234 located at the top thereof and detachably arranged. The detachable arrangement of the first carrier block 223 and the second carrier block 234 can facilitate the replacement of different types of carrier blocks and has good versatility.

[0035] like Figure 4 As shown, the first carrier block 223 is provided with a sensor hole 2231 , and a sensor is provided in the sensor hole 2231 . Similarly, the second carrier block 234 is also provided with a sensor for sensing whether a shell workpiece 500 is placed on the first carrier block 223 or the second carrier block 234 .

[0036] In this embodiment, the plurality of first support seats 220 and the plurality of second support seats 230 cooperate to support parallel surfaces of the housing workpiece 500 but at different heights. In one embodiment, the plurality of second support seats 230 are located in the first region, that is, the second support seats 230 are located inside the first support seats 220. Figure 3 As shown, when supporting from the front, the first support seat 220 supports the edge ring portion 510 of the shell workpiece 500 from the bottom, and the second support seat 230 supports the bottom large surface 520 of the shell workpiece 500 from the bottom. Since the edge ring portion 510 is higher than the bottom large surface 520, at this time, the second carrier block 234 is lower than the first carrier block 223. If it is necessary to support the shell workpiece 500 from the reverse side, the shell workpiece 500 is turned 180°, and the stage assembly 200 supports the shell workpiece 500 from the opposite side, as shown in FIG. Figure 7 and Figure 8 As shown, the first support seat 220 still supports the edge ring portion 510 of the shell workpiece 500 from the bottom. At this time, the second support seat 230 supports the inner large surface 530 from the bottom, and the inner large surface 530 is located above the edge ring portion 510. The second carrier block 234 supports the inner large surface 530 from the bottom by rising to a certain height. As can be seen from the above, the second support seat 230 can support the front and back sides of the shell workpiece 500 after the height is adjustable, without the need to set up a separate back side support fixture, and using the same fixture for image information acquisition is more conducive to ensuring the accuracy of the acquired image, which has the advantages of high detection efficiency and detection accuracy.

[0037] In another case, multiple second support seats 230 are located outside the first area formed by multiple first support seats 220. When supporting from the front, the first support seat 220 supports the bottom large surface 520 from the bottom, and the second support seat 230 supports the edge ring 510 from the bottom, and the edge ring 510 is higher than the bottom large surface 520. At this time, the second carrier block 234 is higher than the first carrier block 223; when supporting from the back, the first support seat 220 supports the inner large surface 530 from the bottom, and the second support seat 230 supports the edge ring 510 from the bottom, and the edge ring 510 is lower than the inner large surface 530. At this time, the second carrier block 234 is lower than the first carrier block 223, and the height adjustment needs to be performed through the second support seat 230.

[0038] Preferably, if Figure 2 As shown, there are four first support seats 220, and the four first support seats 220 are distributed at the four corners of the bottom plate 210. The bottom plate 210 is rectangular, and a plurality of through openings 211 are provided on the bottom plate 210, and the through openings 211 are used for passing the line and reducing weight. The second support seat 230 is located in the first area. There are four second support seats 230, and the four second support seats 230 are distributed at the four corners of the first area.

[0039] Specifically, Figure 4 and Figure 5 As shown, the first support seat 220 includes a fixing seat 221 disposed on the bottom plate 210, a connecting arm 222 disposed on the top of the fixing seat 221, and a first carrier block 223 detachably disposed on the top of the connecting arm 222. The connecting arm 222 at least includes a first arm 2221 extending along a first direction and a second arm 2222 extending along a second direction, the first arm 2221 is connected to the second arm 2222, the first direction is perpendicular to the second direction, and at least one of the first arm 2221 and the second arm 2222 is provided with the first carrier block 223. Furthermore, the connecting arm 222 also includes a third arm 2223, the third arm 2223 is connected to the second arm 2222, and at least one of the first arm 2221, the second arm 2222 and the third arm 2223 is provided with the first carrier block 223.

[0040] For ease of understanding, with the base plate 210 as a reference, the first direction is the long side direction of the base plate 210, and the second direction is the wide side direction of the base plate 210. The third arm 2223 extends along the third direction. Figure 4 As shown, the third direction is distributed at an obtuse angle to the first direction, or, as Figure 5 As shown, the third direction is parallel to the first direction. The multi-directional extension of the connecting arm 222 is conducive to realizing the multi-angle and multi-directional position distribution of the first carrier block 223 to adapt to the housing workpiece 500 of different shapes.

[0041] like Figure 6As shown, the second support seat 230 includes a cylinder seat 231 fixed on the bottom plate 210, a cylinder 232 arranged on the cylinder seat 231, a layer plate 233 arranged on the piston rod of the cylinder 232, and a second carrier block 234 arranged on the layer plate 233, wherein the movement of the piston rod of the cylinder 232 can realize the lifting movement of the second carrier block 234. The layer plate 233 can be adapted to multiple second carrier blocks 234, and the purpose of adapting multiple second carrier blocks 234 is also to improve versatility. Only one second carrier block 234 can be arranged on the layer plate 233, or multiple second carrier blocks 234 can be arranged, depending on the specific structure of the shell workpiece 500.

[0042] In one embodiment, if Figure 4 As shown, the top surface of the first carrier block 223 is provided with convex parts 2232 distributed along its edge, and the convex parts 2232 make the first carrier block 223 have a step-shaped limiting structure, wherein the step-shaped limiting structure is used to limit the edge of the shell workpiece 500. Similarly, the second carrier block 234 can also be provided with the above-mentioned step-shaped limiting structure, which will not be described one by one here.

[0043] like Fig. 9 As shown, the stage assembly 200 is arranged on the base 100 through the moving module 400, and the moving module 400 includes a first linear module 410 and a second linear module 420. The first linear module 410 is arranged on the base 100, and the second linear module 420 has a mold base 421. The second linear module 420 is connected to the first linear module 410 through the mold base 421, and the bottom plate 210 is connected to the second linear module 420. When the first linear module 410 moves, it drives the second linear module 420 and the stage assembly 200 to perform linear reciprocating motion along the first direction. When the second linear module 420 moves, it drives the stage assembly 200 to perform linear reciprocating motion along the second direction. The first linear module 410 and the second linear module 420 can move simultaneously.

[0044] The base 100 is also provided with a baffle 430 surrounding the mobile module 400, wherein the top surface of the baffle 430 is lower than the bottom plate 210. The baffle 430 can ensure the safety of the pedestrian passages on both sides of the platform assembly 200. The bottom of the base 100 is also provided with a shock absorbing module 110, which can be a shock absorbing foot ring, a shock absorbing wheel, or a shock absorbing pad. The shock absorbing module 110 can effectively reduce the vibration between the base 100 and the ground during the movement of the mobile module 400.

[0045] like Figure 1As shown, the visual component 300 includes a gantry support 310 disposed on the base 100, a manipulator 320 disposed on the gantry support 310, and a camera module 330 disposed at the end of the manipulator 320. The manipulator 320 is a multi-degree-of-freedom manipulator, which enables the camera module 330 to collect image information of the shell workpiece 500 from different angles. The manipulator 320 is located directly above the stage assembly 200, which effectively improves the collection effect of image information.

[0046] The arrangement in which the stage assembly 200 can move relative to the base 100, while the visual assembly 300 cannot move relative to the base 100, is more conducive to the image information collection of the visual assembly 300. The movement of the visual assembly 300 is not conducive to the positioning of the camera module 330, affecting the accuracy of image capture.

[0047] Obviously, the above described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
