[0002] Magnetic steel sheets refer to thin sheet-shaped permanent magnets made of materials such as AlNiCo alloy, Samarium Cobalt, ferrite, and Neodymium Iron Boron. Magnetic steel sheet zinc plating equipment is a device specifically designed to plate a layer of zinc onto the surface of magnetic steel sheets. It utilizes electrochemical or thermochemical reactions to form a zinc coating on the surface of the magnetic steel sheet. This zinc coating can significantly improve the corrosion resistance and service life of the magnetic steel sheet, while also helping to improve its surface quality and appearance.

[0003] Most existing galvanizing equipment uses unidirectional fixing when fixing magnets. Since different magnets have different sizes, if the fixing structure in the equipment is not easy to adjust, the equipment may be difficult to adapt to magnets of different sizes. This may lead to frequent replacement or adjustment of the equipment during the galvanizing process, which will affect the uniformity and efficiency of galvanizing.

[0004] Therefore, most of the existing galvanizing devices fix the magnets in a unidirectional manner, which may make it difficult for the device to adapt to magnets of different sizes. This leads to frequent replacement or adjustment of the device during the galvanizing process, which affects the uniformity and efficiency of galvanizing. A magnet galvanizing device can be designed with an adjustable fixing structure so that the magnets can be fully galvanized. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment: a galvanizing device for magnetic steel sheets, including an outer housing 1 and a fixing assembly; the inner side of the outer housing 1 is provided with two sets of fixing assemblies for adjusting and fixing according to the size of the magnetic steel sheets. The fixing assembly includes a snap-fit ​​plate 201, with a square telescopic sleeve 202 installed at each end of the snap-fit ​​plate 201. A square telescopic post 204 is fitted inside the square telescopic sleeve 202. A connecting plate 205 is provided below the snap-fit ​​plate 201 and is fixedly connected to the square telescopic post 204. Multiple sets of rectangular telescopic sleeves 206 are installed at horizontal intervals at the lower end of the connecting plate 205. Four sets of rectangular telescopic sleeves 206 are arranged around the perimeter. An L-shaped telescopic plate 207 is fitted and connected between every two sets of rectangular telescopic sleeves 206. Positioning pins 208 are symmetrically provided on both sides of the connection between the L-shaped telescopic plate 207 and the rectangular telescopic sleeve 206. Multiple sets of positioning holes 209 are symmetrically opened along the sides of the L-shaped telescopic plate 207.

[0022] Please see Figure 2In this embodiment, an inner box 101 is installed inside the outer box 1, forming a U-shaped groove 102 between the inner box 101 and the outer box 1. A heating wire 103 is provided between the inner box 101 and the outer box 1. Two sets of rectangular snap-fit ​​grooves 104 are symmetrically opened longitudinally on both sides of the inner wall of the inner box 101. By controlling the operation panel 108, the power module 109 is started, and the heating wire 103 is energized to start dissipating heat and heat the zinc liquid in the inner box 101. A rectangular cover plate 105 is provided above the outer box 1. Two sets of handles 106 are horizontally installed on the upper end of the rectangular cover plate 105. A U-shaped sealing ring 107 is installed at the lower edge of the rectangular cover plate 105. The U-shaped sealing ring 107 drives the rectangular cover plate 105 to fit and connect with the outer box 1 and the inner box 101 along the U-shaped groove 102. When the handles 106 are lifted, the U-shaped sealing ring 107 drives the rectangular cover plate 105 to fit and connect with the outer box 1 and the inner box 101 along the U-shaped groove 102. 2. The outer casing 1 and the inner casing 101 are fitted together. An operation panel 108 is installed on one side of the outer casing 1. A power module 109 connected to the heating wire 103 is provided on one side of the operation panel 108. A temperature sensor 110 (model JASUN-M12) is provided on the side of the operation panel 108 away from the power module 109, passing through the outer casing 1 and the inner casing 101 and extending into the inner casing 101. The temperature sensor 110 monitors the temperature change of the zinc liquid in real time. A water outlet pipe 111 is provided at the corner of one side of the outer casing 1, passing through the outer casing 1 and the inner casing 101 and fixedly connected to the inner casing 101. A sealing cap 112 is fitted on the end of the water outlet pipe 111 away from the outer casing 1. After this batch of magnetic steel sheets is galvanized, the sealing cap 112 is loosened and the zinc liquid is discharged through the water outlet pipe 111 to see if it can be processed and reused.

[0023] Please see Figures 3-4 In this embodiment, the two ends of the snap-fit ​​plate 201 are positioned and connected to the inner box 101 along the rectangular snap-fit ​​groove 104. The upper end of the square telescopic sleeve 202 is equipped with a cylinder 203. After placement, the snap-fit ​​plate 201 is lifted and its two ends are positioned and connected to the inner box 101 along the rectangular snap-fit ​​groove 104. The positioning pin 208 passes through the rectangular telescopic sleeve 206 and is positioned and connected to the L-shaped telescopic plate 207 through the positioning hole 209. After confirming that there is no error, the positioning pin 208 is picked up, passes through the rectangular telescopic sleeve 206 and is positioned and connected to the L-shaped telescopic plate 207 through the positioning hole 209 to fix the position.

[0024] During operation, the zinc liquid is first poured into the inner box 101. Then, depending on the size of the galvanized magnetic steel sheet, two or more sets of rectangular telescopic sleeves 206 are selected. By adjusting the positioning pin 208, the length and width of the L-shaped telescopic plate 207 are adjusted along the rectangular telescopic sleeve 206. After confirming that everything is correct, the positioning pin 208 is picked up and passed through the rectangular telescopic sleeve 206 and positioned and connected to the L-shaped telescopic plate 207 through the positioning hole 209 to fix the position. Then, the magnetic steel sheet is inserted between the four sets of rectangular telescopic sleeves 206 and placed. After the placement is completed, the snap-fit ​​plate 201 is lifted and its two ends are positioned and connected to the inner box 101 along the rectangular snap-fit ​​groove 104. Then, the handle 106 is lifted and the U-shaped sealing ring 107 drives the rectangular cover plate 105 to fit and connect with the outer box 1 and the inner box 101 along the U-shaped groove 102.

[0025] After all the items are placed, the power module 109 is started under the control of the operation panel 108. The heating wire 103 is powered on and begins to emit heat to heat the zinc liquid in the inner box 101. At the same time, the temperature sensor 110 monitors the temperature change of the zinc liquid in real time. When the temperature rises to a suitable level, the square telescopic column 204 drives the connecting plate 205 to move downward along the square telescopic sleeve 202, driven by the cylinder 203, until the magnetic steel sheet is completely submerged in the zinc liquid for galvanizing. After this batch of magnetic steel sheets is galvanized, the sealing cap 112 is loosened and the zinc liquid is discharged through the outlet pipe 111 to see if it can be processed for reuse.

[0026] Through the above steps, the fixing assembly is adjusted and fixed according to the required size of the galvanized magnetic steel sheet. Then, the fixing assembly is positioned and snapped into the inner box 101 in the outer box 1. The zinc liquid is then heated, and finally, the magnetic steel sheet is immersed in the zinc liquid for galvanizing. Through the adjustable fixing structure, it can adapt to magnetic steel sheets of different sizes and shapes without the need to replace or adjust other parts, which improves galvanizing efficiency and flexibility. It can also reduce galvanizing defects caused by improper position or inaccurate angle of the magnetic steel sheet, such as incomplete galvanizing and uneven galvanizing. This solves the problem that most existing galvanizing devices fix the magnetic steel sheet in one direction, which may make it difficult for the device to adapt to magnetic steel sheets of different sizes, resulting in frequent replacement or adjustment of the device during the galvanizing process, which will affect the uniformity and efficiency of galvanizing.
