Description

Technical Field

[0001] The utility model relates to the technical field of bamboo material processing, in particular to a bamboo strip appearance visual inspection platform. Background Art

[0002] The applicant applied for a Chinese patent in the early years: A bamboo strip color selection machine, patent number: ZL 202022913255.0, authorization publication date: 2021.07.27. It discloses a machine frame, the frame is provided with: a detection mechanism, the detection mechanism is provided with a bamboo strip inlet, a bamboo strip outlet and a detection device, the detection device includes a color detection device, etc.; wherein the color detection device includes components such as a color sensor and a light-emitting unit. The detection mechanism obtains the information of the bamboo strips and detects and classifies the bamboo strips according to different colors, thereby overcoming the problem of sorting errors easily caused by color difference of the human eye and improving the efficiency of visual inspection of the appearance of the bamboo strips.

[0003] Although the detection mechanism overcomes the problem of sorting errors easily caused by color difference of the human eye, thereby improving the efficiency of visual inspection of the appearance of bamboo strips, there are still some shortcomings in the operation of the mechanism. The structural design of the mechanism is not ideal, especially the stability of the detection mechanism is not good. The vibration generated when the bamboo strips pass through the detection mechanism is easily transmitted to the color detection device, thereby affecting its visual inspection effect; and the inspection effect of the color detection device is not ideal. Generally, the color inspection of the bamboo strips is performed on one side (that is, the color inspection of the upper surface of the bamboo strips). Although the orientation of the bamboo strips (that is, the yellow side facing up or the green side facing up) can be solved, there is a lack of visual inspection of the bamboo strips as a whole, and the visual inspection of the appearance of the bamboo strips is not refined enough, so it is difficult to screen out high-quality bamboo strip products. Utility Model Content

[0004] The utility model provides a bamboo strip appearance visual inspection table, which aims to overcome the technical problems that the existing inspection mechanism is not ideal, the stability is not good, the vibration generated when the bamboo strip passes through the inspection mechanism is easily transmitted to the color detection device, thereby affecting its visual inspection, and the visual inspection of the bamboo strip appearance is not refined enough, so it is difficult to screen out high-quality bamboo strip products.

[0005] In order to achieve the purpose, the technical solution provided by the utility model is as follows:

[0006] A visual inspection platform for the appearance of bamboo strips comprises a split frame, a conveying platform installed on the split frame and used for bamboo strips to pass through, and a visual inspection device for visually inspecting the four sides of the bamboo strips on the conveying platform, wherein the front side of the conveying platform is an entrance for the bamboo strips, and the rear side is an exit for the bamboo strips; the split frame comprises an inspection platform arranged inside and outside and an inspection frame placed in the inspection platform, and the inspection platform is provided with an openable box cover; the visual inspection device is installed on the inspection platform, and the conveying platform is installed on the inspection frame.

[0007] Furthermore, an anti-collision strip cover is provided at the bamboo strip entrance.

[0008] Furthermore, the box cover is a flip-up box cover, the right bottom of which is movably connected to the inspection table, and a worker can open the left side of the flip-up box cover by hand; the left and right sides of the upper half of the flip-up box cover are both inclined surfaces.

[0009] Furthermore, the visual detection device includes a first visual detection component, a second visual detection component, a third visual detection component and a fourth visual detection component for performing visual detection on the four sides of the bamboo strips on the conveying platform respectively; the first, second, third and fourth visual detection components all include structured light that emits lasers to the sides of the bamboo strips and generates structured light beams on the corresponding sides, as well as a camera that takes pictures of the sides of the bamboo strips to obtain image information, a camera bracket for supporting the camera, and a structured light bracket for supporting the structured light.

[0010] Furthermore, the conveying platform is also provided with a length detection mechanism for detecting the length of the bamboo strips, and the length detection mechanism includes a roller counter located behind the bamboo strip entrance.

[0011] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the structural design of the visual inspection table is ideal, and a split frame design is adopted (i.e., the inspection table and the inspection frame are arranged inside and outside), that is, the inspection table and the inspection frame are installed separately, so as to prevent the vibration generated when the bamboo strip passes through the inspection frame from being transmitted to the inspection table, thereby affecting the visual inspection effect of the appearance of the bamboo strip. The design of using a visual inspection device to visually inspect the four sides of the bamboo strip, that is, the visual inspection of the entire bamboo strip, can not only identify the orientation of the bamboo strip (i.e., whether the yellow side faces up or the green side faces up); it can also select various defects such as depressions, missing edges and unilateral missing edges, cracks, worm eyes, etc. The visual inspection of the appearance of the bamboo strip is more comprehensive and refined, and high-quality bamboo strip products can be screened out.
