[0035] In this embodiment, a mosquito coil packaging box conveyor belt 12 is provided at the end position of the host frame 1 corresponding to the end of the feeding mechanism for conveying the mosquito coil packaging box for the manipulator to put the mosquito coil support into the mosquito coil packaging box. The mosquito coil packaging box conveyor belt 12 is not part of the present invention.

[0036] In this embodiment, the feeding mechanism mainly includes a feeding channel 8, a horizontal transmission channel 9 and a material bin 10. The material bin 10 is arranged corresponding to the starting end of the feeding channel 8, and the horizontal transmission channel 9 is arranged corresponding to the end of the feeding channel 8. Mosquito coil supports are stored in the material bin 10, and the mosquito coil supports can be gradually put onto the feeding channel 8, and the mosquito coil supports are transported to the horizontal transmission channel 9 through the feeding channel 8, and then the mosquito coil supports are sent to the first manipulator 3 and the second manipulator 4 through the horizontal transmission channel 9. In this embodiment, the material bin 10 can adopt a vibrating disk mechanism or a conveyor belt structure. In this embodiment, the material bin 10 is fixedly installed on the material bin support 11.

[0037] In this embodiment, the feeding channel 8 is inclined, and a scraping mechanism 40 is arranged on the feeding channel 8. A mosquito coil support channel 42 is formed between the scraping mechanism 40 and the feeding channel 8. The height of the mosquito coil support channel 42 is greater than or equal to the thickness of one mosquito coil support and less than the thickness of two mosquito coil supports. The stacked mosquito coil supports can be scraped off by the scraping mechanism 40 to prevent the stacked mosquito coil supports from entering the horizontal transmission channel 9.

[0038] In this embodiment, there are two sets of scraping mechanisms 40, and the two sets of scraping mechanisms 40 are arranged in parallel corresponding to the feeding channel 8. In this embodiment, a redundant structure design is adopted, which can make the scraping effect of the stacked mosquito coil supports better. The scraping mechanism 40 includes a scraping plate 43, a first L-shaped bracket 44 and a second L-shaped bracket 45. Screw holes 46 are respectively formed at both ends of the scraping plate 43. Both the first L-shaped bracket 44 and the second L-shaped bracket 45 are in an "L" shape. A first waist-shaped hole 47 is formed on one surface, and a second waist-shaped hole 48 is formed on the other surface. The first waist-shaped hole 47 is installed together with the screw hole 46 through a screw, and the second waist-shaped hole 48 is installed on the side baffle 41 through a screw. Since the first waist-shaped hole 47 and the second waist-shaped hole 48 are adopted in this embodiment, it is convenient to adjust the height of the mosquito coil support channel 42 between the scraping mechanism 40 and the feeding channel 8.

[0039] In this embodiment, side baffles 41 are respectively and fixedly arranged on both sides of the feeding channel 8, and the mosquito coil supports can be blocked by the side baffles 41 to prevent them from falling from the side.

[0040] In this embodiment, a rear baffle is arranged corresponding to the starting end position of the feeding channel 8. When the mosquito coil support slides down from the feeding channel 8, it can be blocked by the rear baffle to prevent it from scattering.

[0041] In this embodiment, the optical acquisition device uses an industrial camera to collect image information on the horizontal transmission channel 9. In this embodiment, a gantry 2 is fixedly installed on the main frame 1, and the gantry 2 straddles above the horizontal transmission channel 9, and the industrial camera is fixedly installed in the gantry 2.

[0042] In this embodiment, the material return mechanism mainly includes a receiving tray 5, an uploading channel 6, and a sliding channel 7. The receiving tray 5 is arranged below the tail end of the horizontal transmission channel 9. The mosquito coil holders that are not grabbed on the horizontal transmission channel 9 will naturally fall into the receiving tray 5. The receiving tray 5 is inclined. The starting end of the uploading channel 6 corresponds to the tail end of the receiving tray 5. The mosquito coil holders on the receiving tray 5 will naturally slide onto the uploading channel 6 under the action of their own gravity. The uploading channel 6 is inclined. A driving motor is arranged on the uploading channel 6. The uploading channel 6 can be driven by the driving motor to convey the mosquito coil holders. The sliding channel 7 corresponds to the tail end of the uploading channel 6. The mosquito coil holders on the uploading channel 6 will naturally fall into the sliding channel 7. The tail end of the sliding channel 7 corresponds to the starting end of the feeding channel 8. The sliding channel 7 is inclined. The mosquito coil holders on the sliding channel 7 will naturally slide onto the feeding channel 8 under the action of their own gravity for the next cycle.

[0043] When the present utility model is in use, the mosquito coil holders in the material bin 10 fall onto the feeding channel 8 and are conveyed to the horizontal transmission channel 9 through the feeding channel 8. The feeding channel 8 and the horizontal transmission channel 9 are respectively driven by motors to move. The mosquito coil holders are conveyed to the first manipulator 3 and the second manipulator 4 through the horizontal transmission channel 9 and are grabbed and placed into the mosquito coil packaging boxes by the first manipulator 3 and the second manipulator 4. The mosquito coil holders that are not grabbed fall into the material return mechanism and are sent back to the feeding channel 8 through the material return mechanism for the next cycle. During this process, the position information of the mosquito coil holders on the horizontal transmission channel 9 can be collected by the optical acquisition device to make the grabbing by the first manipulator 3 and the second manipulator 4 more accurate. The first manipulator 3 and the second manipulator 4 can respectively grab two mosquito coil holders and put them into different mosquito coil packaging boxes. Or the first manipulator 3 can be used as the main manipulator. When the first manipulator 3 makes an empty grab, the second manipulator 4 makes up for it.

[0044] The present utility model grabs and places the mosquito coil holders through the manipulator, which can greatly improve the production efficiency. In addition, the present utility model adopts a dual-manipulator redundant design, which can further improve the production efficiency and also ensure the reduction of the possibility of missing placement.
