Description

Technical Field

[0001] This utility model relates to the field of magnetic attraction technology for metal packaging cans, specifically a magnetic attraction mechanism for a magnetic attraction robotic arm for metal packaging cans. Background Technology

[0002] A magnetic robotic arm is a type of robotic arm that uses magnetic force to attract objects. Its application in metal packaging cans is mainly reflected in automated packaging production lines, especially in the handling and palletizing processes, where it can greatly improve production efficiency.

[0003] Currently, the magnetic attraction mechanism on the magnetic attraction robotic arm for metal packaging cans cannot adjust the number of packaging cans to be attracted each time according to the needs of use, thus failing to meet different production and stacking requirements. Therefore, we propose a magnetic attraction mechanism for the magnetic attraction robotic arm for metal packaging cans. Utility Model Content

[0004] The purpose of this utility model is to provide a magnetic suction mechanism for a metal packaging can magnetic suction robotic arm, which has the advantage of being able to easily adjust the number of metal packaging cans to be suctioned each time according to the needs of use, so as to be suitable for different production and palletizing requirements, thus improving applicability. This solves the problem that the magnetic suction mechanism on the current metal packaging can magnetic suction robotic arm cannot adjust the number of packaging cans to be suctioned each time according to the needs of use, thus failing to adapt to different production and stacking requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic suction mechanism for a magnetic suction robotic arm for metal packaging cans, comprising an adsorption plate, a cover plate fixedly mounted on the upper surface of the adsorption plate, a plurality of through holes evenly spaced in a rectangular array on the upper surface of the cover plate, a sliding rod slidably inserted inside each through hole, a magnet fixedly connected to the bottom end of each sliding rod, a limit ring fixedly mounted on the outer surface of each sliding rod, a spring spirally wound on the outer surface of each sliding rod below the limit ring, a pin hole provided near the top end of the outer surface of each sliding rod, a fixing frame fixedly mounted on the upper surface of the cover plate, a cylinder fixedly mounted inside the fixing frame, and a lifting plate fixedly connected to the output end of the cylinder, an insertion port provided on the upper surface of the lifting plate above each through hole.

[0006] Preferably, a connecting plate is fixedly installed on the upper surface of the fixing frame, and the connecting plate is provided with a connecting hole, through which bolts pass and fix the connecting plate to the magnetic mechanical arm.

[0007] Preferably, grooves are symmetrically provided on both sides of the outer surface of the lifting plate, the main view of the fixing frame is "n", and the lifting plate passes through the fixing frame, so the two sides of the fixing frame are inserted into the grooves, which plays a limiting role in the lifting process of the lifting plate and improves the stability of the lifting plate.

[0008] Preferably, a slip ring is slidably sleeved on the outer surface of each slide rod at a position above the limiting ring. Each slip ring has a threaded hole on its outer surface, and a screw is movably inserted into each threaded hole. The slip ring slides on the outer surface of the slide rod, and the screw is inserted into the pin hole after rotation, with the screw acting as a pin.

[0009] Preferably, the cover plate and the adsorption plate are fixedly connected by bolts, and the cover plate fixed by bolts is easy to disassemble and assemble.

[0010] Preferably, a grid plate is fixedly installed on the lower surface of the cover plate. The grid plate can separate the magnets inside the adsorption plate to avoid the magnets from affecting each other due to magnetic attraction.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up an adsorption plate, cover plate, through-hole, slide rod, spring, limiting ring, pin hole, fixing frame, cylinder, lifting plate, and insertion port, achieves the effect of easily adjusting the number of metal packaging cans to be adsorbed each time according to the needs of use, so as to suit different production and palletizing requirements, thus improving the applicability. The fixing frame is fixed to the magnetic suction robotic arm, and pins are inserted into the pin holes. The number of pins inserted into the pin holes is controlled according to the number of metal packaging cans to be adsorbed. When the cylinder drives the lifting plate to descend, the obstruction of the pins causes the lifting plate to force the slide rod to drive the magnet to descend to the inner bottom of the adsorption plate. At the same time, the spring is compressed. The slide rod without pins passes through the insertion port and will not drive the magnet to descend. The magnet located at the inner bottom of the adsorption plate adsorbs the metal packaging cans to the lower surface of the adsorption plate. When the adsorbed metal packaging cans are released, the cylinder drives the lifting plate to rise and reset, the compressed spring is released, and the slide rod drives the magnet to rise. The magnet moves away from the metal packaging cans, and the metal packaging cans adsorbed to the lower surface of the adsorption plate are released.

[0013] 2. By setting grooves, this utility model achieves the effect of improving the stability of the lifting plate. The main view of the fixed frame is "n", and the lifting plate passes through the fixed frame. The two sides of the fixed frame are inserted into the grooves, which play a limiting role in the lifting process of the lifting plate and improve the stability of the lifting plate.

[0014] 3. This utility model uses a grid plate to separate the magnets inside the adsorption plate, so as to avoid the magnets from affecting each other due to magnetic attraction. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a magnetic suction mechanism for a magnetic suction robotic arm for metal packaging cans, including an adsorption plate 1. The adsorption plate 1 is hollow inside and open at the top. A cover plate 2 is fixedly installed on the upper surface of the adsorption plate 1. The cover plate 2 and the adsorption plate 1 are fixedly connected by bolts, which facilitates the disassembly and assembly of the cover plate 2. Several through holes 3 are evenly spaced in a rectangular array on the upper surface of the cover plate 2. A slide rod 4 is slidably inserted into each through hole 3. The two ends of the slide rod 4 are located inside and outside the adsorption plate 1, respectively. A magnet 11 is fixedly connected to the bottom end of each slide rod 4. The magnet 11 is located inside the adsorption plate 1. A limit ring 13 is fixedly installed on the outer surface of each slide rod 4. The limit ring 13 is located above the cover plate 2.

[0023] Each slide rod 4 has a spring 12 spirally wound on its outer surface below the limiting ring 13. The spring 12 is located between the cover plate 2 and the limiting ring 13. Each slide rod 4 has a pin hole 17 near the top of its outer surface. Each slide rod 4 has a sliding ring 16 slidably sleeved on its outer surface above the limiting ring 13. Each sliding ring 16 has a threaded hole 15 on its outer surface, and a screw 14 is movably inserted into each threaded hole 15. The sliding ring 16 slides on the outer surface of the slide rod 4. After the screw 14 rotates, it is inserted into the pin hole 17, and the screw 14 acts as a pin. A fixing frame 9 is fixedly installed on the upper surface of the cover plate 2. A connecting plate 10 is fixedly installed on the upper surface of the fixing frame 9. A connecting hole is provided on the upper surface of the fixing frame 9. After the bolt passes through the connecting hole, the connecting plate 10 is fixed to the magnetic suction robotic arm. A cylinder 8 is fixedly installed inside the fixing frame 9, and a lifting plate 6 is fixedly connected to the output end of the cylinder 8. An insertion port 5 is provided on the upper surface of the lifting plate 6 above each through hole 3.

[0024] In use, the connecting plate 10 is fixed to the magnetic suction robotic arm, and pins are inserted into the pin holes 17. The number of pins inserted into the pin holes 17 is controlled according to the number of metal packaging cans to be adsorbed. When the cylinder 8 drives the lifting plate 6 to descend, the obstruction of the pins causes the lifting plate 6 to force the slide rod 4 to drive the magnet 11 to descend to the inner bottom of the adsorption plate 1. At the same time, the spring 12 is compressed. The slide rod 4 without pins passes through the insertion port 5 and will not drive the magnet 11 to descend. The magnet 11 located at the inner bottom of the adsorption plate 1 adsorbs the metal packaging cans onto the lower surface of the adsorption plate 1. When the adsorbed metal packaging cans are released, the cylinder 8 drives the lifting plate 6 to rise and reset. The compressed spring 12 is released, and the slide rod 4 drives the magnet 11 to rise. The magnet 11 moves away from the metal packaging cans, and the metal packaging cans adsorbed onto the lower surface of the adsorption plate 1 are released.

[0025] Example 2

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the magnetic attraction mechanism of the magnetic attraction robotic arm for metal packaging can proposed by this utility model, compared with the first embodiment, also includes grooves 7 symmetrically provided on both sides of the outer surface of the lifting plate 6, and a grid plate 18 fixedly installed on the lower surface of the cover plate 2. The grid plate 18 can separate the magnets 11 inside the adsorption plate 1 to avoid the magnets 11 from affecting each other due to magnetic attraction.

[0027] In this embodiment, the main view of the fixing frame 9 is "n", and the lifting plate 6 passes through the fixing frame 9. The two sides of the fixing frame 9 are inserted into the groove 7, which plays a limiting role in the lifting process of the lifting plate 6 and improves the stability of the lifting plate 6.

[0028] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
