[0036] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood in a broad sense, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0037] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0038] As shown in Figure 1 , the present application provides a detection device, which acquires the image of the workpiece 100 in a visual detection manner, and judges whether the position, clarity and other indicators of the sprayed code meet the standard. Specifically, the workpiece 100 in the present application is a bottle body product.

[0039] Among them, the detection device includes a support body 101, an image capturing assembly and a lighting assembly. The support body 101 is used to carry the image capturing assembly and the lighting assembly, the image capturing assembly is used to acquire the image of the workpiece 100, and the lighting assembly provides light for the workpiece 100 to ensure the clarity of the captured image. In addition, the lighting assembly can adjust the elevation angle, so as to adjust the irradiation direction of the light and change the lighting mode of the workpiece 100. The image capturing assembly captures the image of the workpiece 100 under different lighting modes, which improves the accuracy of detection.

[0040] In some examples, as shown in Figure 2 , the support body 101 is used to place the image capturing assembly and the lighting assembly, so that the image capturing assembly and the lighting assembly have stable positions, which ensures that the image capturing assembly can accurately capture the image of the workpiece 100, and also ensures that the lighting assembly can accurately irradiate the light to the workpiece 100, thereby improving the lighting conditions of the workpiece 100.

[0041] Further, as shown in Figure 3 , the image capturing assembly is connected to the support body 101, and the image capturing assembly includes an image capturing component 201. Specifically, the image capturing component 201 adopts a camera. The image capturing component 201 is used to shoot the image of the workpiece 100. When the workpiece 100 is a bottle body product and the sprayed code attached to the bottle body needs to be detected, the image capturing component 201 faces the sprayed code.

[0042] At the same time, as shown in Figure 4 , the lighting assembly is connected to the support body 101, and the lighting assembly includes a light source 301 and a first angle adjusting assembly. The light source 301 is used to provide light for the workpiece 100. When the workpiece 100 is a bottle body product and the sprayed code attached to the bottle body needs to be detected, the light source 301 faces the sprayed code. Specifically, the light source 301 adopts a lamp.

[0043] In addition, the light source 301 is connected to the support main body 101 through a first angle adjusting assembly. Under the action of the first angle adjusting assembly, the light source 301 rotates relative to the support main body 101. It can be understood that when the light source 301 rotates, the elevation angle of the light source 301 changes, and the direction of the light of the light source 301 also changes, thereby changing the illumination mode of the workpiece 100.

[0044] It is worth noting that due to the specific structure of the workpiece 100, single-angle light irradiation may not truly reflect the appearance of the workpiece 100. With the rotation of the light source 301, the workpiece 100 will be irradiated by light of multiple angles, avoiding the limitation of single illumination mode. Comprehensive analysis of the images of the workpiece 100 under multiple illumination modes is beneficial to improve the accuracy of detection.

[0045] In some examples, as shown in Figure 5 The first angle adjusting assembly includes a first guide component 302 and a first rotating shaft 303, and the first guide component 302 is arranged on the support main body 101. The light source 301 is rotationally connected to the first guide component 302, and the light source 301 and the support main body 101 are indirectly rotationally connected. When the light source 301 rotates, the direction of the light of the light source 301 changes.

[0046] Specifically, the first guide component 302 is rotationally connected to the light source 301 through the first rotating shaft 303, and the outer wall of the light source 301 is provided with a corresponding handle, which facilitates manual adjustment of the elevation angle of the light source 301 by the staff.

[0047] In some examples, the first guide component 302 is provided with a first guide groove 304, and the first guide groove 304 matches the movement path of the light source 301. Since the light source 301 rotates, the first guide groove 304 extends in an arc shape.

[0048] Further, the first guide component 302 is provided with a first locking component, and the outer wall of the light source 301 is provided with a corresponding locking hole. Specifically, the first locking component adopts a fastener, and the locking hole adopts a threaded hole. The locking hole is in communication with the first guide groove 304. When the light source 301 is adjusted to the required elevation angle, the first locking component is connected to the locking hole through the first guide groove 304, thereby locking the position of the light source 301, so that the elevation angle is maintained.

[0049] It can be understood that the two side ends of the first guide groove 304 define the limit elevation angle of the light source 301. When the first locking component is at the end of the first guide groove 304 and is connected to the light source 301, the light source 301 is at the limit elevation angle position.

[0050] In some examples, the support body 101 is formed as a hollow shell, and the image capturing assembly and the illumination assembly are both arranged inside the support body 101. In order to ensure that the image capturing component 201 can capture the image of the workpiece 100 and the light source 301 can illuminate the workpiece 100, the side wall of the support body 101 is provided with a light-transmitting portion 102. The image capturing component 201 captures the image of the workpiece 100 through the light-transmitting portion 102, and the light emitted by the light source 301 passes through the light-transmitting portion 102 to illuminate the workpiece 100. Specifically, the illumination assembly is provided with two groups, which are respectively arranged at the top and the bottom of the internal space of the support body 101. The light emitted by the light source 301 at the top is inclined downward to illuminate the workpiece 100, and the light emitted by the light source 301 at the bottom is inclined upward to illuminate the workpiece 100, so as to ensure that the workpiece 100 is sufficiently illuminated.

[0051] In some examples, as shown in Figure 3 The image capturing assembly includes a distance adjusting assembly, and the image capturing component 201 is connected to the inside of the support body 101 through the distance adjusting assembly. Under the action of the distance adjusting assembly, the distance between the image capturing component 201 and the workpiece 100 can be adjusted, so as to capture the image of the workpiece 100 according to actual needs.

[0052] Further, the distance adjusting assembly includes a fixed seat 202 and a moving seat 203. The fixed seat 202 is fixedly connected to the inside of the support body 101, and the image capturing component 201 is connected to the moving seat 203. The moving seat 203 is slidingly connected to the fixed seat 202, so as to drive the image capturing component 201 to move.

[0053] Specifically, the moving seat 203 is provided with a third guide groove 204 and is provided with a third locking component, and the fixed seat 202 is provided with a corresponding locking hole. The locking hole is in communication with the third locking component. When the image capturing component 201 is adjusted to the required position, the third locking component passes through the third guide groove 204 and is connected to the locking hole, so as to lock and maintain the position of the image capturing component 201.

[0054] In some examples, as shown in Figure 6 The detection device further includes a support 401. The support 401 is kept upright, and the support body 101 is connected to the support 401 and can be adjusted in height along the support 401. Specifically, the support body 101 is indirectly connected to the support 401, and a height adjusting assembly is connected between the support body 101 and the support 401.

[0055] In some examples, the height adjusting assembly includes a lead screw 402 and a sliding block 403. The lead screw 402 is connected to the support 401 and is arranged upright and can rotate on the support 401.

[0056] The two ends of the screw rod 402 are connected to the support frame 401 through a retainer 404, which is used to ensure the relative position of the screw rod 402 and the support frame 401 stable, and the end of the screw rod 402 is rotatably inserted into the retainer 404 to avoid interfering with the rotation process of the screw rod 402.

[0057] Further, the slider 403 is used to connect the support body 101, the screw rod 402 passes through the slider 403 and is engaged with the slider 403, and the screw rod 402 and the slider 403 form a screw rod 402 nut mechanism. When the screw rod 402 rotates, the screw rod 402 drives the slider 403 to move along the axial direction of the screw rod 402. With the movement of the slider 403, the support body 101 also moves, thereby adjusting the height.

[0058] In addition, in order to make the screw rod 402 and the slider 403 rotate relative to each other and ensure the normal operation of the screw rod 402 nut mechanism, the support frame 401 is provided with a guide rod 405. The guide rod 405 is arranged side by side with the screw rod 402, and multiple guide rods 405 can be provided. The guide rod 405 passes through the slider 403 and guides the movement of the slider 403, avoiding the slider 403 rotating together with the screw rod 402.

[0059] In some examples, as shown in Figure 7 and Figure 8 The second angle adjusting assembly is arranged between the height adjusting assembly and the support body 101, that is, the second angle adjusting assembly is arranged between the slider 403 and the support body 101.

[0060] The second angle adjusting assembly includes a connecting component 406, which is fixedly connected to the slider 403 and formed as a plate structure, and the connecting component 406 is rotatably connected to the support body 101. Further, the connecting component 406 and the support body 101 are rotatably connected through a second rotating shaft 407, so that the support body 101 rotates relative to the support frame 401, thereby adjusting the elevation angle of the support body 101.

[0061] In some examples, the support body 101 is provided with a second guide groove 408, which matches the movement path of the support body 101. Since the support body 101 rotates, the second guide groove 408 extends in an arc shape, and multiple second guide grooves 408 can be provided.

[0062] Further, the support body 101 is provided with a second locking component, and the connecting component 406 is provided with a corresponding locking hole. Specifically, the second locking component adopts a fastener, and the locking hole adopts a threaded hole. The locking hole is in communication with the second guide groove 408, and when the support body 101 is adjusted to the required elevation angle, the second locking component passes through the second guide groove 408 and is connected to the locking hole, thereby locking the position of the support body 101, so that the elevation angle can be maintained.

[0063] In some examples, as shown in Figure 9 The detection device further comprises a sensing component 501 and a third angle adjusting assembly, the sensing component 501 is used to sense whether there is a workpiece 100 in the detection area of the detection device, so as to ensure the normal operation of the detection device.

[0064] The sensing component 501 is connected to the support main body 101 through the third angle adjusting assembly, and under the action of the third angle adjusting assembly, the sensing component 501 can adjust the elevation angle to ensure the accuracy of the sensing process.

[0065] Further, the third angle adjusting assembly comprises a second guide component 502 and a third rotating shaft 503, and the sensing component 501 is connected to the outer top of the support main body 101 through the second guide component 502. The sensing component 501 is rotationally connected to the second guide component 502, so that the sensing component 501 is indirectly rotationally connected to the support main body 101, and the sensing direction of the sensing component 501 changes when the sensing component 501 rotates. Specifically, the second guide component 502 is rotationally connected to the sensing component 501 through the third rotating shaft 503.

[0066] In some examples, the second guide component 502 is provided with a fourth guide groove 504, and the fourth guide groove 504 matches the angle adjusting path of the sensing component 501. Since the sensing component 501 rotates, the fourth guide groove 504 extends in an arc shape, and a plurality of fourth guide grooves 504 can be provided.

[0067] Further, the second guide component 502 is provided with a fourth locking component, and the outer wall of the sensing component 501 is provided with a corresponding locking hole.
