Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for linear motor production, specifically to a magnet positioning and bonding device for a linear motor. Background Technology

[0002] The stator of a linear motor, such as Figure 1 As shown, it mainly includes a base plate and magnets glued to the upper surface of the base plate. The traditional assembly of the magnets involves first gluing labels with holes corresponding to the magnet mounting positions to the upper surface of the base plate, then applying adhesive to each hole, and finally placing the magnets one by one and pressing them together. Because the labels are easily damaged and have poor recyclability, a more rigid positioning frame was subsequently developed, such as... Figure 2 As shown, the positioning frame includes a rectangular frame and first lower spacers spaced apart within the rectangular frame. Adjacent first lower spacers cooperate with the rectangular frame to form positioning holes. However, during use, we found that the magnets sometimes break when positioned.

[0003] Therefore, we propose a magnetic positioning and bonding device for linear motors. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a magnet positioning and bonding device for linear motors, which overcomes the deficiencies of existing technologies, is reasonably designed, easy to use, and solves the technical problem that magnets may break during the use of existing positioning frames.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A magnet positioning and adhesive device for a linear motor includes a positioning frame. The positioning frame includes a rectangular frame and first lower partitions spaced apart within the rectangular frame. The inner cavity of the rectangular frame is divided by a set of first lower partitions to form a plurality of lower positioning holes. A ramp extending from top to bottom is provided on one side of the lower positioning holes along their length direction.

[0009] Furthermore, the device includes a tray, a positioning seat, a push rod, and a linear drive unit. The inner cavity of the tray is divided by a set of spaced second partitions to form a plurality of upper positioning holes. The front side of the inner cavity of the tray is provided with an opening and is sealed by an openable insert plate.

[0010] A positioning groove is formed on the positioning seat;

[0011] The positioning frame is detachably mounted on the front side of the positioning seat via a positioning component. The tray is positioned and mounted in the positioning groove. The bottom surface of the inner cavity of the tray is flush with the upper surface of the positioning frame. The upper positioning hole and the lower positioning hole correspond one-to-one.

[0012] The push rod is provided in a set and corresponds one-to-one with the upper positioning hole. The push rod passes through the rear side wall of the positioning seat and the rear side wall of the tray and then extends into the upper positioning hole.

[0013] The linear drive unit is used to drive the push rod to push the magnet forward.

[0014] Furthermore, the upper surface of the positioning frame adjacent to the positioning seat is provided with an upwardly protruding first upper partition, and each of the first upper partitions is located on the same straight line as the first lower partition and is connected to each other.

[0015] Furthermore, the positioning frame and the base plate are positioned by the positioning assembly and locked in place by the locking member.

[0016] Furthermore, the positioning component includes a pair of positioning pins, and the locking element is a locking bolt.

[0017] Furthermore, a group of the push rods are connected to the same synchronizing rod, and the linear drive unit is an electric push rod, the output end of which is connected to the synchronizing rod.

[0018] (III) Beneficial Effects

[0019] This utility model provides a magnet positioning and adhesive device for a linear motor, which has the following advantages: the positioning frame is not only more rigid than the label paper, but also thicker. Correspondingly, the height difference between the upper and lower positioning holes increases. Since the magnet is a neodymium magnet, it is relatively brittle. When the operator places it, it may break due to excessive force or improper angle. Therefore, in this application, a transition ramp is provided at the end of each lower positioning hole, which can greatly reduce the occurrence of magnet breakage.

[0020] Furthermore, the arrangement of structures such as trays, positioning seats, push rods, and linear drive units enables the mass assembly of magnets. At the same time, the magnets are pre-positioned in the trays, which can further shorten the batch interval time of assembly and improve efficiency. Attached Figure Description
