Description

Technical Field

[0001] The utility model relates to a magnetizing device, in particular to a double-end surface automatic magnetizing device. Background Art

[0002] Magnetization is to magnetize magnetic materials or increase the magnetism of magnets with insufficient magnetism. Generally, the magnetic object to be magnetized is placed in the magnetic field formed by a coil through which direct current passes. Magnetization is completed by a magnetizing device (magnetizer). The magnetizing device comes with a magnetizing fixture. During magnetization, the workpiece to be magnetized is placed in the working position of the magnetizing fixture, and a certain magnetizing voltage and current are connected. After the discharge is completed, the workpiece to be magnetized has the required magnetic properties. Due to the variety of magnetizing methods and magnetizing waveforms, magnetic products after magnetization are widely used in new energy vehicles, smart home appliances, various sensors and other fields.

[0003] Different clamps need to be used for magnetization according to different products and customer requirements. In the field of bonding magnets, radial magnetization and end magnetization are the most common methods. According to customer needs, some workpieces require the two end faces of the product to have the same magnetic properties. At this time, the operator needs to put the product on top of one of the clamps and align it, then cover the other clamp on the top of the workpiece and align it, then magnetize and discharge, and finally remove the upper clamp and remove the workpiece. The whole operation process is cumbersome and inefficient, and the magnetization clamp is heavy and not suitable for long-term operation. Utility Model Content

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] Example 1: See Figures 1 to 4 , a double-end automatic magnetizing equipment, including a magnetizing device with a double-sided magnetizing fixture, the double-sided magnetizing fixture includes an upper clamp body 4 and a lower clamp body 5, both of which are cylindrical and arranged oppositely, and the upper clamp body 4 can move downward to clamp the workpiece 9 to be magnetized between the upper clamp body 4 and the lower clamp body 5;

[0026] It also includes a guide rail 1, a material collection box 3, a first cylinder 6, a second cylinder 7, and a controller;

[0027] The guide rail 1 is arranged horizontally, with a feed hopper 2 arranged just above one end, and the other end is in contact with the outer wall of the lower clamp 5, and the upper surface of the guide rail 1 is flush with the upper surface of the lower clamp 5;

[0028] The position on the guide rail 1 facing the outlet of the feed hopper 2 is station one 10, the magnetizing fixture is station two 11, and station three 12 is provided on the extension line of the guide rail 1, the station three 12 is close to station two 11, and the collection box 3 is located directly below station three 12;

[0029] A U-shaped aluminum fork 8 is horizontally provided on the upper surface of the guide rail 1. The aluminum fork 8 is formed by splicing a semicircular hole and a rectangular hole. The diameter of the semicircular hole is the same as that of the notch, the upper clamp body 4 and the lower clamp body 5, and is larger than the diameter of the workpiece 9 to be magnetized. The opening of the aluminum fork 8 faces the guide rail 1, and the opening direction is parallel to the width direction of the guide rail 1.

[0030] The aluminum fork 8 is connected to a two-dimensional translation mechanism, and the two-dimensional translation mechanism is used to drive the aluminum fork 8 to translate along the width direction and the length direction of the guide rail 1;

[0031] The starting point of the width direction translation is when the projections of the aluminum fork 8 and the guide rail 1 on the horizontal plane do not overlap, and the end point is when the center of the semicircular hole coincides with the width center of the guide rail 1;

[0032] The starting point of the longitudinal translation is that the center of the semicircular hole coincides with the center of the station 10, and the end point is that the center of the semicircular hole coincides with the center of the station 3 12;

[0033] The controller is connected to the two-dimensional translation mechanism and the magnetizing device to control the operation of the two.

[0034] The two-dimensional translation mechanism is composed of a first cylinder 6 and a second cylinder 7 arranged horizontally, the piston rod of the first cylinder 6 is parallel to the width direction of the guide rail 1 and connected to the aluminum fork 8, and is used to drive the aluminum fork 8 to move, and the piston rod of the second cylinder 7 is parallel to the length direction of the guide rail 1 and connected to the first cylinder 6, and is used to drive the first cylinder 6 and the aluminum fork 8 to move. However, it is not limited to this mechanism, and the two-dimensional translation mechanism can also be a two-dimensional linear translation platform, a mechanical arm, etc., as long as it can drive the aluminum fork 8 to move.

[0035] The feed hopper 2 is made of stainless steel, and the aluminum fork 8 and the guide rail 1 are made of aluminum.

[0036] The other end of the guide rail 1 is fitted with the outer wall of the lower clamp 5. Specifically, a semicircular notch is provided at one end of the guide rail 1 facing the lower clamp 5. The diameter of the notch is the same as the outer diameter of the lower clamp 5. The guide rail 1 is matched and fitted with the lower clamp 5 through the notch.

[0037] The thickness of the workpiece 9 to be magnetized is h, the distance between the bottom of the feed hopper 2 and the upper surface of the guide rail 1 is d1, h<d1<2h, and the distance between the lower surface of the aluminum fork 8 and the upper surface of the guide rail 1 is d2, d2<h.

[0039] Regarding control: the upper clamp 4 itself can move downward, and clamp the workpiece 9 to be magnetized together with the lower clamp 5. The two-dimensional translation mechanism belongs to the existing technology. The controller controls the movement of the two-dimensional translation mechanism and the operation of the magnetization equipment. The software has not been improved, and it is also controlled using existing technology.

[0040] A workflow of the utility model is:

[0041] 1. In the initial state, the two-dimensional translation mechanism makes the aluminum fork 8 located at the starting point of the translation in the width direction and the starting point of the translation in the length direction, that is, the position outside the station 10 and not overlapping with the guide rail 1 in the horizontal plane;

[0042] 2. The workpiece 9 to be magnetized falls to the workstation 10 through the feed hopper 2;

[0043] 3. The two-dimensional translation mechanism drives the aluminum fork 8 to translate in the width direction of the guide rail 1 until the center of the semicircular hole coincides with the width center of the guide rail 1. At this time, the aluminum fork 8 is located directly below the workstation 10, and the workpiece 9 to be magnetized enters the aluminum fork 8;

[0044] 4. The two-dimensional translation mechanism drives the aluminum fork 8 and the workpiece to be magnetized 9 to translate in the length direction of the guide rail 1 to the second station 11, between the upper clamp body 4 and the lower clamp body 5;

[0045] 5. The upper clamp body 4 moves downward to clamp the workpiece 9 to be magnetized, and performs the magnetization operation until the magnetization is completed, and then the upper clamp body 4 moves upward;

[0046] 6. The two-dimensional translation mechanism drives the aluminum fork 8 and the workpiece to be magnetized 9 to translate in the length direction of the guide rail 1 to the workstation 3 12 and enter the collection box 3;

[0047] 7. The two-dimensional translation mechanism drives the aluminum fork 8 to translate in the width direction of the guide rail 1 to the starting position in the width direction, and then drives the aluminum fork 8 to translate in the length direction of the guide rail 1 to the starting position in the length direction.

[0048] This cycle is repeated to achieve automatic double-end magnetization operation.

[0049] Taking the existing magnetizing fixture weighing about 2.5Kg and double-end magnetization as an example, workers need to move the fixture repeatedly, which is very labor-intensive. The current manual magnetization rate is 25-30s / piece. After using the utility model, the magnetization rate can reach 8-10s / piece.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
