Description

An automatic magnet recharging device Technical Field

[0001] This utility model relates to the field of magnet processing technology, and more specifically, to an automatic magnetizing device. Background Technology

[0002] Magnets are widely used in daily life and industry. Generally, the main function of magnets is to utilize their mutual attraction and repulsion functions. The requirements for the distribution of their magnetic field and the uniformity of their magnetic force are not high. Therefore, the design focus of traditional magnetization equipment is more on the quantitative magnetization problem in order to ensure the magnetic force of the magnet.

[0003] Application No. CN202420111635.8 discloses an automatic magnet magnetizing device, relating to the technical field of magnet production equipment. This automatic magnet magnet magnet magnetizing device includes a magnetizing box, a support platform fixed to the bottom of the magnetizing box, and a belt conveyor for conveying magnets fixed to the top of the support platform. The belt conveyor is located inside the magnetizing box, and a feeding assembly is provided on the top of the belt conveyor for feeding unmagnetized magnets one by one. The feeding assembly includes a storage cylinder, which is positioned above the conveyor belt of the belt conveyor. This invention, through the setting of the belt conveyor and the feeding assembly, allows the piston rod of the cylinder to continuously extend and retract, causing a pusher plate to push out multiple unmagnetized magnets one by one from the storage cylinder. The belt conveyor then transports the unmagnetized magnets through the magnetizing box for magnetization, improving the automation level of the magnetizing process, thereby saving manpower and increasing magnetizing efficiency.

[0004] However, the above scheme does not include a magnet feeding mechanism. When magnetizing magnets that still retain magnetism, the stacked magnets and the magnets in the feeding device are prone to attracting each other, which makes it impossible for the conveyor belt to separate the magnets one by one and feed them, thus preventing the magnets from being fed and magnetized.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an automatic magnetizing device, which has the following advantages:

[0017] (1) This utility model adopts a feeding device with a first motor, a disc cam, a discharge port, a guide rod, a follower, a pusher block, a guide sleeve, and a spring. The first motor drives the disc cam at its output end to rotate. Since the L-shaped follower abuts against the side of the disc cam, and the guide sleeve on the L-shaped follower is sleeved with the guide rod with the spring, and the pusher block at the lower end of the L-shaped follower is located behind the discharge port of the feeding device, as the disc cam rotates, the follower drives the pusher block to reciprocate under the guidance of the guide sleeve and the guide rod. This allows the pusher block to push the stacked magnets in the feeding device out of the discharge port one by one during the reciprocating motion, thus solving the problem of magnets with residual magnetism attracting each other and being unable to feed.

[0018] (2) In this utility model, a collection box and an inclined guide hopper are set at the tail of the base frame. As the magnet is conveyed by the conveyor belt, the magnet is conveyed to the tail of the conveyor belt and falls into the collection box under the guidance of the inclined guide hopper until the magnet falls into one of the collection baskets in the collection box. At this time, since the collection box drives two parallel sliding rods to connect the two collection baskets, the semi-enclosed sliding sleeves on both sides of the collection basket slide along the surface of the sliding rods by manually pulling the collection basket. With this structure, it is easy to collect the magnet after it is magnetized and the two collection baskets can be collected alternately. It is also convenient to quickly transfer and pick up the collection baskets. Attached Figure Description

After the collection basket 9 is full, the other collection basket 9 is replaced to continue collecting magnets.
