DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a technical solution: a magnet plate for a linear motor, comprising a substrate 1 and a resin plate 9, wherein a plurality of magnet parts 7 are provided on the upper surface of the substrate 1, and the plurality of magnet parts 7 are all provided inside the resin plate 9, and a protective member 13 is installed on the upper surface of the resin plate 9;

[0021] The protective part 13 includes a protective panel 131. The upper surface of the protective panel 131 is provided with multiple groups of wear-resistant ribs 134. Both sides of the protective panel 131 are fixedly connected with multiple groups of fixing blocks 132. The lower ends of the two corresponding groups of fixing blocks 132 are integrally formed with a card block 133. Side holes 12 for embedding the card blocks 133 are provided on both sides of the resin plate 9. The lower surface of the protective panel 131 is provided with an adhesive layer 135 bonded to the resin plate 9. The protective panel 131 is directly bonded to the resin plate 9 using the adhesive layer 135. The adhesive layer 135 is 3M glue with a high bonding effect, so that the resin layer and the protective panel 131 fit tightly, thereby preventing the protective panel 131 from separating from the resin layer when the slider moves, and the card block 133 on the fixed block 132 is embedded in the side hole 12 on the resin layer to further improve the stability of the installation of the protective panel 131.

[0022] Multiple groups of wear-resistant ribs 134 are arranged at equal intervals, multiple groups of fixed blocks 132 are arranged at equal intervals, and multiple groups of fixed blocks 132 are arranged in a straight line. Through multiple groups of wear-resistant ribs 134 and contact with sliders (not shown in the figure, it is existing technology and will not be repeated), the wear-resistant ribs 134 have high wear resistance, thereby reducing abrasion, having a longer service life, and reducing the number of times the magnet plate is maintained. At the same time, the injection molding material of the resin plate 9 selects high-quality materials such as epoxy resin or phenolic resin. These materials not only provide sufficient protection, but also can withstand various environmental conditions that may be encountered during the operation of the linear motor. By using injection molding technology, magnet plates with complex shapes can be manufactured quickly and at low cost while ensuring high precision and consistency.

[0023] The lower surface of the resin plate 9 is provided with magnet fitting grooves 10 for embedding multiple groups of magnet parts 7, and a limiting groove 11 is provided between two adjacent groups of magnet fitting grooves 10. The magnet fitting grooves 10 are used to facilitate the storage of the magnet parts 7, reduce the overall thickness of the magnet plate, and thus reduce the space occupancy rate of the linear magnet when in use, and the limiting grooves 11 are used in conjunction with the blocking strips 5 to separate adjacent magnet parts 7, ensuring that the spacing between the magnet parts 7 is the same and the magnetism generated by the magnet parts 7 is uniform.

[0024] The upper surface of the substrate 1 is provided with multiple groups of magnet placement grooves 4 for embedding the magnet part 7. The multiple groups of magnet placement grooves 4 are arranged at equal intervals. The magnet part 7 can be quickly positioned through the multiple groups of placement grooves, thereby improving the efficiency of magnet plate production, ensuring the stability of the magnet part 7, and facilitating the magnetization treatment of the magnet part 7.

[0025] A plurality of groups of blocking bars 5 are fixedly connected to the upper surface of the substrate 1, and the plurality of groups of blocking bars 5 are alternately arranged in an offset manner with the plurality of groups of magnet placement slots 4. The plurality of groups of blocking bars 5 are respectively embedded in the plurality of groups of limiting slots 11. The plurality of groups of blocking bars 5 are used to conveniently separate the magnet parts 7 so that the magnet parts 7 are arranged at equal distances, thereby ensuring the uniform magnetic properties of the magnet parts 7 after magnetization, and improving the use effect of the linear motor. The magnet part 7 can be a rectangular parallelepiped or other special shapes, such as an outward protruding curved portion composed of a quadratic curve or a circular arc cross-sectional shape. This design is conducive to improving the magnetic properties and enhancing the mechanical strength of the structure.

[0026] The two sets of blocking strips 5 are fixedly connected to the opposite side with a protrusion 6, and the two sides of the magnet part 7 are provided with a groove 8 for the protrusion 6 to be engaged. The protrusion 6 on the blocking strip 5 fits with the groove 8 on the magnet part 7, which improves the stability of the magnet part 7 installed in the placement groove, thereby ensuring the quality of the resin layer after injection molding and increasing the contact area with the resin layer.

[0027] The upper surface of the substrate 1 is provided with multiple groups of hidden holes 2, and the lower surface of the substrate 1 is provided with multiple groups of fixed through holes 3. The multiple groups of fixed through holes 3 are respectively connected to the multiple groups of hidden holes 2. The inner diameter of the hidden hole 2 is larger than the inner diameter of the fixed through hole 3. The hidden holes 2 are used to conveniently hide the bolts on the fixed guide rail, reduce the impact of the bolts on the installation of the magnet plate, and improve the aesthetics.

[0028] When in use, bolts are used to pass through the fixing holes and fixedly connect with the guide rail (a fixing part on the linear motor, used to guide the slider) to complete the installation of the magnet plate on the guide rail. When the slider on the guide rail (a movable part on the linear motor) slides along the guide rail, the slider and the magnetic magnet plate produce friction, thereby facilitating the adjustment of the position of the slider. During the movement, the slider preferentially contacts the wear-resistant ribs 134 on the protective panel 131, reducing the wear on the resin plate 9, thereby improving the protection effect of the resin plate 9, increasing the service life of the magnet plate, and improving the utilization efficiency of the linear motor.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
