Precise positioning of these magnets during installation has always been a key focus in linear motor design. The precision of the magnet installation directly affects the performance of the linear motor, including its output torque, operating efficiency, and smoothness during operation.

[0003] Currently, most linear motor production sites still use manual labor to repeatedly apply individual magnets. This process is tedious, time-consuming, labor-intensive, and the results are not always good. Manual presses are also needed for pressing. However, when using a press to demold, uneven force often causes the magnets on the stator plate to be pulled out or damaged. Utility Model Content

[0007] 1. In the above scheme, the carrier further includes: a body that cooperates with the stator plate and a plurality of receiving grooves spaced apart on one side surface of the body, and the other side surface of the body is used for mounting and connecting with the upper surface of the base plate.

Detailed Implementation

[0020] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0021] Example 1: A magnetic bonding processing mechanism for a linear motor stator. The stator of the linear motor includes a stator plate 101 and a plurality of magnetic strips 102 bonded to the stator plate 101 at intervals. The magnetic bonding fixture includes a base plate 1, a top plate 3 mounted above the base plate 1 by at least two spaced columns 2, and a carrier 4 for loading the magnetic strips 102. A movable plate 5 that can move vertically is provided between the base plate 1 and the top plate 3 for placing the carrier 4. The lower end of a lead screw shaft 61 connected to a drive assembly passes through the top plate 3 and is connected to the movable plate 5. The lead screw shaft 61 and a lead screw nut 62 fixedly mounted on the top plate 3 are engaged by a threaded rotation. An electromagnet 8 is mounted on the lower surface of the movable plate 5 facing the base plate 1. When energized, the electromagnet 8 is used for magnetic attraction with the surface of the stator plate 101 opposite to the magnetic strips 102.

[0022] The aforementioned drive component is a motor; the aforementioned carrier 4 further includes: a body 41 that is configured to cooperate with the stator plate 101 and a plurality of accommodating grooves 42 spaced apart on one side surface of the body 41, and the other side surface of the body 41 is used for mounting and connecting with the upper surface of the base plate 1.

[0023] At least two mounting through holes 43 are provided on the body 41 and on the outside of the receiving groove 42. At least two of the carriers 4 are fixedly connected to the base plate 1 by bolts that are respectively embedded in the mounting through holes 43. The body 41 of the carrier 4 is configured as a ferromagnetic metal body that can be magnetically attracted to the magnetic strip 102.

[0024] Example 2: A magnetizing processing mechanism for a linear motor stator, wherein the stator of the linear motor includes a stator plate 101 and a plurality of magnetic strips 102 bonded to the stator plate 101 at intervals. The magnetizing fixture includes a base plate 1, a top plate 3 mounted above the base plate 1 by at least two spaced columns 2, and a carrier 4 for loading the magnetic strips 102. A movable plate 5 that can move vertically is provided between the base plate 1 and the top plate 3 for placing the carrier 4. The lower end of a lead screw shaft 61 connected to a drive assembly passes through the top plate 3 and is connected to the movable plate 5. The lead screw shaft 61 and a lead screw nut 62 fixedly mounted on the top plate 3 are engaged by a threaded rotation. An electromagnet 8 is mounted on the lower surface of the movable plate 5 facing the base plate 1. When energized, the electromagnet 8 is used for magnetic attraction with the surface of the stator plate 101 opposite to the magnetic strips 102.

[0025] Two electromagnets 8 are installed at intervals along the length of the stator plate 101 on the lower surface of the movable plate 5. The electromagnets are used to attract the stator plate, making the mechanical structure connecting the stator plate to the stator plate simpler and more convenient.

[0026] The aforementioned drive component is a hand crank 7, which is used in conjunction with a lead screw to perform up-and-down displacement for demolding and pressing operations; the aforementioned lead screw shaft 61 and lead screw nut 62 are a T-type lead screw module;

[0027] The manual cranking of the lead screw drives the stator plate to move vertically up and down. The electromagnet attracts the stator plate to achieve a quick clamping effect. The manual component allows for manual clamping of the lead screw shaft at any time. The use of a T-shaped lead screw can achieve effective self-locking and prevent the moving plate from falling.

[0028] The process of magnetizing and demagnetizing is simplified, reducing the waste of human resources; the stator plate is subjected to more uniform force, making it less likely for magnets to fail; the hand crank and lead screw shaft are connected by a flat key and an axial baffle, limiting the radial and axial fit and ensuring transmission accuracy; the overall structure is simple, compact, reliable, and easy to install and adjust.

[0029] The aforementioned four columns 2 are respectively connected to the four corners of the base plate 1 and the top plate 3; each of the aforementioned columns 2 passes through the movable plate 5 and slides with the movable plate 5 through a graphite bushing 51 fixedly installed on the movable plate 5.

[0030] Working principle:

[0031] Apply an accelerator to the cleaned surface of the stator plate to which the magnets are to be applied, and install the stator plate with the surface to which the magnets are to be applied facing down on the base plate.

[0032] Place the electromagnet in an energized state to make it magnetic, and shake the hand crank to rotate the lead screw shaft to drive the electromagnet to move down with the movable plate until the electromagnet is magnetically connected to the upper surface of the stator plate on the base plate.

[0033] By rotating the hand crank in the opposite direction, the screw shaft is rotated, which drives the electromagnet to move up with the movable plate. The stator plate, which is magnetically connected to the electromagnet, moves up and away from the base plate.

[0034] Several magnetic strips to be pasted are sequentially inserted into the receiving slots of the carrier body, so that each magnetic strip inserted into the receiving slot is magnetically attracted and fixed to the bottom surface of the corresponding receiving slot.

[0035] Install the carrier body with the magnetic strips installed on the base plate, and apply black glue to the surface of each magnetic strip in the carrier body facing the stator plate.

[0036] Shake the hand crank again to rotate the lead screw shaft, which drives the stator plate connected to the electromagnet to move down with the movable plate until the lower surface of the stator plate to be magnetized is attached to several magnetic strips coated with glue. Wait one minute.

[0037] By shaking the hand crank in the opposite direction again to rotate the lead screw shaft, the stator plate connected to the electromagnet and the magnetic strip bonded to the stator plate are moved upward, separating the magnetic strip from the carrier body;

[0038] The electromagnet is de-energized and loses its magnetism. The stator plate with the attached magnetic strip is then separated from the demagnetized electromagnet.

[0039] When using the above-mentioned magnetic bonding processing mechanism for the stator of a linear motor, the stator plate is slowly moved to multiple magnetic strips until it is bonded to the magnetic strips. Then, the magnetic strips bonded to the stator plate are demolded by moving the stator plate in the opposite direction. This can save labor costs, improve processing efficiency, improve the positional accuracy of bonding, and facilitate the clamping and placement of the stator plate.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
