Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation of metal foreign matters in energy conservation and environmental protection, and more specifically to a floor sweeping robot for removing magnetic foreign matters. Background Art

[0002] At present, in special production environments, such as when producing lithium battery-related products (for example: diaphragms), since metal foreign matters can cause short circuits in lithium batteries, and most metals are magnetic. During diaphragm production, in addition to ensuring the protection of the components of the operating equipment in the clean room, it is also necessary to protect the ground at various positions to prevent fine metal particles from entering the diaphragm products; during the production in the lithium battery diaphragm workshop, it is necessary to manually clean the magnetic foreign matters on the ground with a manual magnetic bar or a trolley equipped with a magnetic bar. The manual cleaning efficiency is low and it is easy to have omissions, resulting in incomplete cleaning and poor effects. Content of the Utility Model

[0003] 1. Technical problems to be solved by the utility model:

[0004] Aiming at the problems of low efficiency and poor effect of manual cleaning and separating metal foreign matters in the existing special production environment, the utility model provides a floor sweeping robot for removing magnetic foreign matters. Through the coordinated cooperation of a floor sweeping robot with multi-modal perception and adaptive path planning and a magnetic bar, the magnetic foreign matters magnetically attracted by the magnetic bar are sucked into the dust collection bin, so as to achieve the purpose of timely and quickly separating and cleaning the metal foreign matters on the workshop floor.

[0005] 2. Technical solutions:

[0006] To achieve the above purpose, the technical solutions provided by the utility model are as follows:

[0007] A floor sweeping robot for removing magnetic foreign matters includes a main body and rollers installed at the bottom to drive the main body to move. A dust collection bin is built in the main body. An installation groove is reserved at the bottom of the main body. A magnetic bar is rotatably connected in the installation groove. A foreign matter suction port is reserved near the dust collection bin in the installation groove and is communicated with the dust collection bin through the foreign matter suction port. In specific use, the floor sweeping robot selects an existing floor sweeping robot system with multi-modal perception and adaptive path planning. During the movement of the floor sweeping robot, the magnetic bar magnetically attracts metal foreign matters. When the metal foreign matters rotate with the magnetic bar to the foreign matter suction port, they are absorbed into the bin by the dust collection bin with strong suction, so as to achieve the effect of timely and quickly collecting and cleaning the metal foreign matters on the workshop floor.

[0008] As a further technical solution, in the installation groove, a scraper is connected near the dust collection bin. Both ends of the scraper are fixedly connected to the side walls of the installation groove. The working end at the bottom of the scraper is close to the arc surface of the magnetic bar. The length of the scraper is adapted to the length of the foreign matter suction port. After scraping off the magnetic foreign matters magnetically attracted by the magnetic bar, it is easier to be immediately sucked into the dust collection bin, so as to improve its magnetic attraction working efficiency.

[0009] A further technical solution is that the mounting groove is arranged between the two rollers; the magnetic bar is connected to the two rollers for synchronous rotation through the support rods connected to its two sides, and rotates synchronously with the rollers. While no additional driving force is required for the magnetic bar, the effect of improving the magnetic suction working surface can be achieved, thereby further improving its magnetic suction working efficiency.

[0010] According to a further technical solution, the bottom arc surface of the magnetic rod is slightly higher than the bottom wheel surface of the roller to avoid interference in their mutual movement.

[0011] According to a further technical solution, the magnetic flux of the magnetic bar is 500-12000 GS.

[0012] 3. Beneficial effects:

[0013] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] The utility model discloses a sweeping robot for removing magnetic foreign matter, which makes full use of the existing sweeping robot system with multi-modal perception and adaptive path planning, and cooperates with the magnetic rod and the scraper. During the movement of the sweeping robot, the magnetic rod attracts metal foreign matter, and when the metal foreign matter rotates to the foreign matter suction port with the magnetic rod, the scraper scrapes off the magnetic foreign matter attracted by the magnetic rod, and then the dust collection bin with strong suction force absorbs the foreign matter into the bin, thereby achieving the effect of timely and rapid centralized separation, collection and cleaning of metal foreign matter on the workshop floor, and energy-saving, environmentally friendly and environmentally friendly.

As shown in Figure 1 , 3 , 4, and 5, it includes a main body 1, two rollers 3 installed at the bottom to drive the main body 1 to move, and a guide wheel 4 in front of the rollers 3. The main body 1 is usually circular and internally provided with a dust suction bin 12. An installation groove 11 is reserved at the bottom of the main body 1. A magnetic bar 2 is rotatably connected in the installation groove 11, and the installation groove 11 forms an installation space for accommodating and adapting to the length and size of the magnetic bar 2; a foreign object suction port 111 is reserved near the dust suction bin 12 in the installation groove 11, and is communicated with the dust suction bin 12 through the foreign object suction port 111 to form an absorption channel of the dust suction bin 12.

[0024] In the specific use of the floor sweeping robot for removing magnetic foreign objects in this embodiment, it can be used at a time different from the working hours, or can be used at any time for 24 hours a day, that is, continuously and automatically cleaned for 24 hours. The floor sweeping robot selects an existing floor sweeping robot system with multi-modal perception and adaptive path planning. During the movement of the floor sweeping robot on the workshop floor according to the set path planning, the magnetic bar 2 magnetically attracts metal foreign objects. When the metal foreign objects rotate with the magnetic bar 2 to the foreign object suction port 111, they are absorbed into the bin by the dust suction bin 12 with strong suction, thereby achieving the effect of collecting and cleaning the metal foreign objects on the workshop floor at a different time or in a timely and rapid manner, and the environment is friendly after the metal foreign objects are cleaned.

[0025] Embodiment 2

Both ends of the scraper 5 are fixedly connected to the side wall of the installation groove 11. The bottom working end of the scraper 5 is close to the arc surface of the magnetic bar 2. The length of the scraper 5 is adapted to the length of the foreign object suction port 111. After scraping off the magnetic foreign objects magnetically attracted by the magnetic bar 2, it is easier to be immediately sucked into the dust suction bin, so as to improve its magnetic attraction working efficiency.

[0027] The bottom arc surface of the magnetic bar 2 is slightly higher than the bottom wheel surface of the roller 3 to avoid mutual movement interference. The magnetic flux of the magnetic bar 2 is 500 - 12000 GS, which can adsorb fine metal particles of different specifications as much as possible.

[0028] As shown in Figure 1 , 4As shown in the figure, the installation groove 11 is preferably arranged near the position of the diameter length between the two rollers 3; the magnetic bar 2 is rotationally connected to the two rollers 3 synchronously through the support rods connected to both sides thereof, and rotates synchronously with the rollers 3. The two support rods are the first support rod 21 and the second support rod 22 respectively. The second support rod 22 is connected to the axle of the roller 3 through the driving coupling head 6, and this roller 3 is the driving wheel; the first support rod 21 rotates synchronously with the roller 3 through the bearing 7, and this roller 3 is the driven wheel, or can also be the driving wheel, with dual-wheel drive. By driving the magnetic bar 2 to rotate synchronously through the driving wheel, without adding additional driving force to the magnetic bar 2, and the magnetic bar 2 is arranged between the two rollers 3, it can also achieve the effect of improving the magnetic adsorption working surface as much as possible, further improving its magnetic adsorption working efficiency and thorough cleaning effect, and moreover, it is energy-saving, environmentally friendly, and environmentally friendly.
