[0002] In the modern industrial production system, the identification and labeling links of products are crucial. Precise and efficient labeling can not only improve the appearance quality of products, but also facilitate the identification, traceability and market promotion of products.

[0003] With the rapid development of automation technology, labeling robotic arms have gradually been applied in industrial production. Labeling robotic arms have the advantages of high speed, precision, stability, etc., and can greatly improve the labeling efficiency and quality. However, in order to facilitate the precise picking of labels by a labeling robotic arm covering a suction cup, a camera is often assembled on the labeling robotic arm. The camera takes pictures of the labels to obtain the image information of the labels, and then the control system analyzes and processes the images to determine the position and posture of the labels.

[0004] During use, the surface of the camera lens will be contaminated with dust, particles and other pollutants. When the surface of the camera lens is contaminated with more dust, particles and other pollutants, it will affect the optical performance of the camera, making it impossible to accurately obtain the image information of the labels, and ultimately resulting in the inability of the labeling robotic arm covering the suction cup to accurately pick the labels. In view of this, the present utility model is specifically proposed. Summary of the Utility Model

Specific implementation mode

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0022] Embodiment 1:

[0023] Refer to Figure 1 , Figure 2 , Figure 3 , a labeling robotic arm with a positioning component, including a robotic arm 1 installed on a workbench, and further including: a mounting plate 101 detachably connected to the output end of the robotic arm 1, a rolling component, and a multi-hole vacuum suction cup 301, both of which are connected to the mounting plate 101. Among them, a positioning camera 2 for assisting the multi-hole vacuum suction cup 301 to pick up labels is fixedly installed on the mounting plate 101; a lifting seat 5 is liftably connected to the mounting plate 101. Among them, a rotating shaft 501 is rotatably connected to the lifting seat 5, a cleaning disc 502 is fixedly connected to the rotating shaft 501, a brush 503 is arranged on the cleaning disc 502, a suction nozzle 504 is arranged on the cleaning disc 502, and a hollow cavity 505 communicating with the suction nozzle 504 is opened on the rotating shaft 501 and the cleaning disc 502; a filter box 6 and a vacuum pump 602 are fixedly installed on the mounting plate 101. Among them, the output end of the vacuum pump 602 is communicated with the filter box 6, the input end of the vacuum pump 602 is fixedly communicated with a conduit 603, and the conduit 603 is connected to the hollow cavity 505 through a rotary joint 604, and the rotary joint 604 is arranged on the rotating shaft 501.

[0024] The mounting plate 101 is fixedly connected with the electric telescopic rod 7 , and the lifting seat 5 is fixedly mounted on the output end of the electric telescopic rod 7 .

[0025] An activated carbon filter 601 is inserted into the filter box 6 , and an exhaust hole is opened on the top of the filter box 6 .

[0026] The rolling component includes a mounting seat 4 and a rolling roller 401 rotatably connected to the mounting seat 4, a slide rod 402 is fixedly connected to the mounting seat 4, the slide rod 402 is slidably connected to the mounting plate 101, and one end of the slide rod 402 away from the mounting seat 4 is fixedly connected to a limiting block, and a tension spring 403 is fixedly connected between the limiting block and the mounting plate 101.

[0027] It also includes a cylinder 3 fixedly mounted on the mounting plate 101 , and a porous vacuum suction cup 301 fixedly connected to the output end of the cylinder 3 .

[0028] When it is necessary to label the product, the robot arm 1 drives the mounting plate 101 to move the positioning camera 2 to the top of the label. At this time, the label is photographed by the positioning camera 2 to obtain the image information of the label, and then the control system analyzes and processes the image to determine the position and posture of the label so that the porous vacuum suction cup 301 can accurately take the label. Subsequently, the robot arm 1 drives the mounting plate 101 to move the porous vacuum suction cup 301 to the top of the label. When it moves to the top of the label, the cylinder 3 is started. The cylinder 3 pushes the porous vacuum suction cup 301 downward until it fits with the label, so that the porous vacuum suction cup 301 absorbs the label, and then the robot arm 1 accurately sticks the absorbed label to the designated position on the surface of the product, thereby completing the labeling operation of the product.

[0029] When the lens surface of the positioning camera 2 is contaminated with a lot of dust, particles and other pollutants, which affects the optical performance of the lens of the positioning camera 2 and makes it unable to accurately obtain the image information of the label, the electric telescopic rod 7 is first started, and the electric telescopic rod 7 pushes the cleaning plate 502 to move upward, and when the brush 503 on the cleaning plate 502 contacts the lens surface of the positioning camera 2, it can clean the dust, particles and other pollutants on the lens surface;

[0030] Meanwhile, when cleaning the lens surface of the positioning camera 2, the vacuum pump 602 is started. When the vacuum pump 602 starts to work, it can make the suction nozzle 504 generate negative pressure, so that it can adsorb pollutants such as dust and particles swept from the lens surface. Then, the dust, particles and other pollutants are transported into the filter box 6 through the hollow cavity 505 and the conduit 603 in sequence. A one-way valve is arranged on the conduit 603. When the gas drifts upward in the filter box 6 and contacts the activated carbon filter screen 601, because the activated carbon has a developed pore structure and rich microporous tissues inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter carried in the gas into the micropores, so that it plays a role in filtering the gas. Then, the filtered gas is discharged from the filter box 6 through the exhaust hole;

[0031] In summary, when cleaning the lens surface of the positioning camera 2, the dust, particles and other pollutants swept from the lens surface are inhaled into the filter box 6 for filtration, so as to avoid the dust particles from drifting around the lens and adhering to the lens surface of the positioning camera 2 again, thereby ensuring that the positioning camera 2 after cleaning the lens can accurately obtain the image information of the label, so as to accurately locate the position of the label for taking the label.

[0032] It should be noted that the conduit 603 is a stretchable and shrinkable hose, so the conduit 603 will not interfere with the movement of the cleaning disk 502;

[0033] Specifically, the brush 503 can be made of ultra-fine fiber. The ultra-fine fiber is very soft, and its fiber fineness is usually below 0.4 denier. Such extremely fine fibers enable the cleaning brush to gently wipe when contacting the mirror surface, without generating hard friction, thus greatly reducing the risk of scratching the mirror surface. Moreover, the ultra-fine fiber has adsorption ability and can effectively adsorb pollutants such as dust and oil stains. When cleaning the mirror surface, it can quickly remove stains without the need to wipe too hard, further protecting the mirror surface.

[0034] Embodiment 2:

[0035] Refer to Figure 3 、 Figure 4 A labeling robot arm with a positioning component is basically the same as that in Embodiment 1. Further, a motor 8 is fixedly installed on the lifting seat 5, the output end of the motor 8 is fixedly connected with a first gear 801, the rotating shaft 501 is fixedly connected with a second gear 802, and the second gear 802 is meshed with the first gear 801;

[0036] When cleaning the lens surface of the positioning camera 2, the motor 8 is started. The motor 8 drives the rotation shaft 501 to rotate through the meshing connection between the first gear 801 and the second gear 802. At the same time, when the rotation shaft 501 rotates, it can also drive the cleaning disc 502 to drive the brush 503 to rotate in contact with the lens surface of the positioning camera 2, so that the brush 503 can better clean the dust, particles and other pollutants on the lens surface of the positioning camera 2, thereby improving the cleaning effect of the lens surface of the positioning camera 2.
