Description

Technical Field

[0001] The utility model belongs to the technical field of adsorption disks, in particular to a magnetic adsorption disk structure. Background Art

[0002] A suction cup is a device used to adsorb or suck objects, usually by generating negative pressure or magnetic force to achieve the adsorption function. In industrial production, suction cups are often used to carry, fix, and suck metal, plastic and other objects. They are stable, easy to use, and reliable. Suction cups have various designs and can be installed on various equipment or tools according to specific usage requirements to help people complete adsorption and suction operations.

[0003] In industrial production, magnetic suction cups are usually used to suck up plates of different weights, but there is a problem in the prior art: the magnetic force of the magnetic suction cup is fixed. Therefore, if a magnetic suction cup suitable for heavy plates is used to suck up light plates, multiple light plates will be sucked up at the same time due to excessive magnetic force; conversely, if a magnetic suction cup suitable for light plates is used to suck up heavy plates, it will not be sucked up due to insufficient magnetic force. In this case, workers need to constantly replace different magnetic suction cups according to the weight of different plates, which makes the operation steps cumbersome and time-consuming.

[0004] A magnetic suction cup is disclosed in the patent with publication number CN205342891U. When using the magnetic suction cup with this structure, it only needs to drive the piston to move up and down and drive the permanent magnet away from or close to the bottom surface of the cylinder body to achieve the adsorption or release of the parts. The structure is very simple. In addition, the end cover is detachably set on the cylinder body and the permanent magnet is detachably set on the piston, which can easily realize the replacement of the permanent magnet. Although the magnetic suction cup with this structure can be quickly replaced, it still needs to be frequently used. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] A magnetic adsorption disk structure, hereinafter referred to as the suction disk, such as Figures 1 to 3 As shown, it includes a connecting head 3, a mounting tube 1, a permanent magnetic attraction structure, a driving structure and an electromagnetic magnetic attraction structure; the mounting head is fixedly connected to the top of the mounting tube 1, the permanent magnetic attraction structure is movably connected to the mounting tube 1, and the electromagnetic magnetic attraction structure is fixedly connected to the mounting tube 1;

[0029] The permanent magnetic attraction structure includes an outer disk 8, a guide rod 10, a permanent magnet 7 and a movable disk 14, and the fixed magnetic attraction structure includes a main rod 9 and an electromagnet 6; the driving structure includes a screw 12 and a motor 4;

[0030] The permanent magnet is fixed to the bottom of the outer disk 8, the guide rod 10 is fixed to the top of the outer disk 8, the movable disk 14 is movably connected in the installation tube 1, and the top of the guide rod 10 is fixed to the movable disk 14; the screw 12 is rotatably connected in the installation tube 1, the screw 12 is threadedly connected to the movable disk 14, and the motor 4 is used to drive the screw 12 to rotate; the main rod 9 is fixed to the bottom of the installation tube 1, and the electromagnet 6 is fixed to the bottom of the main rod 9. Among them, the magnetic force of the permanent magnet 7 is smaller than the magnetic force of the electromagnet 6, and the permanent magnetic attraction structure is used to adsorb light plates, such as foamed nickel materials; the electromagnetic magnetic attraction structure is used to adsorb heavy plates, such as steel plates.

[0031] When in use, first fix the suction cup to the movable working arm, absorb the material through the suction cup, and move the material through the moving working arm. Specifically, the electromagnet is not energized when the light plate is absorbed. Before the light plate is absorbed, the height position of the outer disk 8 needs to be adjusted and the bottom of the outer disk 8 needs to be flush with the bottom of the electromagnet 6. The motor 4 drives the screw 12 to rotate, and the movable disk 14 is restricted by the guide rod 10 and cannot rotate, so it moves in the installation tube 1. The movable disk 14 drives the outer disk 8 to move through the guide rod 10. The height of the outer disk 8 is changed by controlling the rotation direction and number of turns of the screw 12. The suction cup is moved to the light plate to be absorbed by controlling the working arm, and the working arm is lowered so that the permanent magnet 7 at the bottom of the outer disk 8 contacts the light plate and absorbs the light plate to the bottom of the outer disk 8. The light plate is transported to the designated position by the working arm. Start the motor 4 and control the outer disk 8 to move upward. The light plate at the bottom of the outer disk 8 is blocked by the electromagnet 6. At this time, the electromagnet 6 without power is not magnetic. When the permanent magnet 7 on the outer disk 8 rises a certain distance, the light plate automatically detaches. When adsorbing the heavy plate, keep the outer disk 8 and the permanent magnet 7 at the top of the electromagnet 6. Use the working arm to move the suction cup to the top of the heavy plate, and make the electromagnet 6 at the bottom of the suction cup contact the heavy plate. Power on to make the electromagnet 6 magnetic, and the electromagnet 6 and the heavy plate are tightly adsorbed together. Use the working arm and the suction cup to carry the heavy plate to the designated position and put it down. Turn off the power to make the electromagnet 6 lose its magnetism, so that the heavy plate and the electromagnet 6 are separated. In this way, the light plate and the heavy plate can be adsorbed separately, and through this setting, the two magnetic suction structures will not interfere with each other, ensuring the normal use of the suction cup.

[0032] In a preferred embodiment, if Figures 1 to 3 As shown, a connecting rod 2 is provided between the connector 3 and the mounting tube 1, and the two ends of the connecting rod 2 are respectively connected to the connector 3 and the mounting tube 1. The connecting rod 2 forms a distance between the mounting tube 1 and the connector 3, which facilitates observation of the situation in the mounting tube 1 and enables timely inspection of the movable disk 14.

[0033] In a preferred embodiment, if Figure 1 As shown, the outer disk 8 is an annular structure, and the outer disk 8 is movably sleeved outside the electromagnet 6. This structure enables the electromagnet 6 to be located in the middle of the outer disk 8. When the light plate is put down, the electromagnet 6 in the middle blocks the light plate, thereby effectively separating the light plate from the permanent magnet 7.

[0034] In a preferred embodiment, if Figures 1 to 3 As shown, a plurality of external positioning heads 11 are fixedly connected to the bottom of the installation cylinder 1. The positioning heads are used to limit the outer disk 8 to prevent the outer disk 8 from moving upward too far, resulting in the outer disk 8 and the installation cylinder 1 being squeezed.

[0035] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a cable connection portion 5 is provided at the bottom of the installation cylinder 1. The cable connection portion 5 is used to facilitate the arrangement of cables so as to facilitate the power supply to the electromagnet 6.

[0036] In a preferred embodiment, if Figure 4 As shown, a plurality of limiting grooves 19 are arranged on the circumference of the movable disk 14, and a plurality of limiting plates 15 are fixedly connected on the circumference of the mounting tube 1, and the limiting plates 15 cooperate with the limiting grooves 19. The cooperation between the limiting grooves 19 and the limiting plates 15 can ensure the stable up and down movement of the movable disk 14. At the same time, the limiting plates 15 can prevent the movable disk 14 from rotating, thereby ensuring the stability of the movable disk 14.

[0037] In a preferred embodiment, if Figure 4 As shown, an internal limit head 13 is fixedly connected to the bottom of the limit plate 15. The internal limit head 13 is used to limit the moving distance of the moving plate 14, so as to prevent the moving plate 14 from excessively moving downward and being squeezed by the mounting cylinder 1.

[0038] In a preferred embodiment, if Figure 2 As shown, a mounting seat 18 is fixedly connected to one side of the mounting cylinder 1, and the motor 4 is fixedly connected to the mounting seat 18; the top of the screw rod 12 extends out of the mounting cylinder 1, and a driven wheel is fixedly connected to the top of the screw rod 12, and a driving wheel 17 is fixedly connected to the output shaft of the motor 4, and the driving wheel 17 is connected to the driven wheel through a belt. In this way, the motor 4 can be set on the side of the mounting cylinder 1, which is convenient for the motor 4 to drive the screw rod 12 to rotate, and at the same time, it is also convenient to repair and replace the motor 4. Further optimized, the driving wheel 17 is connected to the driven wheel through a toothed belt. The toothed belt can ensure the stability of the power transmission between the driving wheel 17 and the driven wheel.
