[0025] Please refer to Figure 1 , Figure 1This is an overall schematic diagram of a visual acquisition device for a packaging box in this application. The visual acquisition device 1 for a packaging box provided in this application includes: a mounting plate 11, a screw drive assembly 13, a camera body 14, a lens assembly 15, and a light source assembly 16. The mounting plate 11 is provided with a through hole 112; the screw drive assembly 13 is installed on one side of the mounting plate 11, and the camera body 14 is connected to the screw drive assembly 13 through transmission and can be moved and adjusted in the vertical direction of the mounting plate 11; the lens assembly 15 passes through the through hole 112 after being assembled with the camera body 14; the light source assembly 16 is installed on the other side of the mounting plate 11 and is arranged adjacent to the lens assembly 15.

[0026] Among them, the number of the light source assemblies 16 is two. The lens assembly 15 is installed between the two light source assemblies 16, and the light emitting directions of the two light source assemblies 16 are the same as the acquisition direction of the lens assembly 15.

[0027] The working principle of the visual acquisition device 1 for a packaging box provided in this application is as follows: According to the size of the packaging box, the staff adjusts the front and rear positions of the camera body 14 through the screw drive assembly 13. The lens assembly 15 assembled with the camera body 14 passes through the through hole 112 and correspondingly adjusts the front and rear positions. The front and rear positions refer to the direction perpendicular to the mounting plate 11.

[0028] Compared with the existing visual acquisition device for a packaging box, the light source assembly 16 in this application is fixedly installed on the mounting plate 11. The staff only needs to adjust the front and rear positions of the lens assembly 15 without considering the synchronous coordination problem of moving the light source assembly 16 and the lens assembly 15 simultaneously. Therefore, the precise position of the lens assembly 15 can be controlled more easily. Through the screw drive assembly 13, the front and rear positions of the camera body 14 and the lens assembly 15 are directly adjusted, so as to ensure that the camera body 14 can quickly focus when shooting and imaging, accurately identify the information on the surface of the packaging box, and effectively improve the recognition efficiency and recognition accuracy of the visual acquisition device 1 for a packaging box.

[0029] Please refer to Figure 2 , Figure 2This is a partial explosion schematic diagram of a visual acquisition device for a packaging box in this application. In this embodiment, the screw drive assembly 13 includes: a screw fixing base 132, a screw 133, and a sliding block 134. The screw fixing base 132 is arranged on the mounting plate 11. The screw 133 is rotatably arranged on the screw fixing base 132, and the screw 133 is perpendicular to the mounting plate 11. The sliding block 134 is provided with a threaded hole 134a, and the sliding block 134 is screwed to the screw 133 through the threaded hole 134a. The camera body 14 is arranged on the sliding block 134. A knob 139 is installed at one end of the screw 133 away from the mounting plate 11.

[0030] The staff manually twists the knob 139, thereby rotating the screw 133, so that the sliding block 134 screwed to the screw 133 moves back and forth along the screw 133, realizing the movement adjustment of the camera body 14 in the vertical direction along the mounting plate 11.

[0031] Corresponding to the cross-sectional shape of the camera body 14, the screw drive assembly 13 further includes: a moving seat 135. In this embodiment, the moving seat 135 is correspondingly in the shape of a cuboid. The moving seat 135 is fixedly installed with the camera body 14 by screws. A groove 134c is provided at the installation position of the sliding block 15 and the moving seat 135. After the moving seat 135 is clamped in the groove 134c, it is fixedly installed with the sliding block 15 by bolts. The camera body 14 is detachably installed at one end of the moving seat 135 away from the sliding block 15.

[0032] Setting the sliding seat 135 avoids directly installing the camera body 14 with the sliding block 134, preventing the camera body 14 from being directly stressed and moved when the sliding block 134 moves, and causing damage to the camera body 14.

[0033] In other embodiments, the shape of the moving seat 135 can be adaptively adjusted corresponding to the cross-sectional shape of the camera body 14. A sliding groove can also be provided at the installation position of the moving seat 135 and the sliding block 15. The sliding block 15 is clamped in the sliding groove, and thus is fixedly installed with the moving seat 135.

[0034] In one embodiment, the screw drive assembly 13 further includes: a plurality of guide rods 136 disposed on the screw fixing base 132 in parallel with the screw 133; the slider 134 is provided with a plurality of guide rod through holes 134b corresponding to the positions of the guide rods 136, and the guide rods 136 pass through the guide rod through holes 134b. Among them, the number of the guide rods 136 is two, adjacent to the screw 133, and the two guide rods 136 are respectively disposed at both ends of the screw 133 and are symmetrically arranged with respect to the screw 133.

[0035] By providing the guide rods 136, the movement direction of the slider 134 can be restricted, ensuring that when the slider 134 moves along the screw 133, it is prevented from rotating or deflecting; and the guide rods 136 can bear and disperse the load from the slider 134, reducing the stress on the screw 133 and the screw fixing base 132, thereby extending the service life of the screw 133 and the screw fixing base 132. In other embodiments, the number of the guide rods 136 can be appropriately adjusted.

[0036] Please refer to Figure 3 , Figure 3 which is a schematic diagram of a locking member of a visual acquisition device for a packaging box according to the present application. The screw drive assembly 13 further includes: a locking member 137, the screw 133 passes through the screw fixing base 132 and partially extends out of the screw fixing base 132, the locking member 137 is provided with a first locking arm 137a and a second locking arm 137b, a screw through hole 137c is formed in the middle of the first locking arm 137a and the second locking arm 137b, and the locking member 137 is fitted and installed on the part of the screw 133 extending out of the screw fixing base 132 through the screw through hole 137a. One ends of the first locking arm 137a and the second locking arm 137b are both provided with locking screw holes 137d.

[0037] After adjusting the positions of the camera body 14 and the lens assembly 15, by screwing a screw into the locking screw hole 137d, the first locking arm 137a and the second locking arm 137b are brought into a locked state, so that the screw through hole 137a restricts the screw 133 from rotating.

[0038] In this embodiment, the screw fixing seat 132 includes a first support plate 132a, a second support plate 132b, and a third support plate 132c. The first support plate 132a is disposed on one side of the mounting plate 11. The first support plate 132a is provided with a first screw through hole 132d. One side of the second support plate 132b is fixedly installed with the first support plate 132a, and the second support plate 132b is disposed perpendicular to the mounting plate 11. The third support plate 132c is disposed on the other side of the second support plate 132b and is disposed opposite to the first support plate 132a. The third support plate 132c is provided with a second screw through hole 132e. The screw 133 is parallel to the second support plate 132b and can rotatably pass through the first screw through hole 132d and the second screw through hole 132e.

[0039] The screw transmission assembly 13 further includes: two ball bearings 138, and the two ball bearings 138 are respectively installed in the first screw through hole 132d and the second screw through hole 132e. By providing the ball bearings 138, the frictional force of the screw 133 on the first screw through hole 132d and the second screw through hole 132e during rotation can be effectively reduced, which not only reduces energy loss but also extends the service lives of the screw 133, the first screw through hole 132d, and the second screw through hole 132e.

[0040] Please refer to Figure 4 , Figure 4 which is an exploded view of the light source assembly and the lens assembly of a packaging box vision acquisition device of the present application. In one embodiment, the light source assembly 16 includes: a light source housing 162, a plurality of lamp beads 164, and a light homogenizing plate 166. The light source housing 162 is installed on the mounting plate 11 and is disposed adjacent to the lens assembly 15. The light homogenizing plate 166 is detachably assembled with the light source housing 162, and the light homogenizing plate 166 and the light source housing 162 form a lamp bead accommodation space. The lamp beads 164 are installed in the lamp bead accommodation space.

[0041] Among them, the lamp beads are LED three-color lamps, and the number is 3. By providing the LED three-color lamps, the packaging box vision acquisition device 1 disclosed in the present application can adaptively adjust the color of the light source according to the color of the surface of the packaging box. The setting of the light homogenizing plate 166 can ensure that the light is evenly distributed in the illumination area, so as to improve the ability of the packaging box vision acquisition device 1 disclosed in the present application to accurately identify the information on the surface of the packaging box, and effectively improve the recognition efficiency and recognition accuracy of the packaging box vision acquisition device 1. Of course, in other embodiments, the number of the lamp beads can be adaptively adjusted according to actual lighting requirements.

[0042] The lens assembly 15 includes a lens mount 152 and a lens 154. The lens mount 152 passes through the through hole 112 and is detachably assembled with the camera body 14 and the lens 154 at its two ends respectively.
