[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] like Figure 1 and Figure 2 As shown, an electromagnet assembly device includes at least a pressing device 20, a winding device 30, a moving iron core pre-assembly device 40, a moving iron core welding device 50, a main body assembly device 60, a finished product pre-assembly device 70, and a retaining ring assembly device 80, combined with... Figures 3 to 11As shown, the pressing device 20 includes a first tooling 21 and a first pressing mechanism 22. The first tooling 21 is used to support the frame 102, and the first pressing mechanism 22 presses the sleeve 103 located thereon into the frame 102 to form a base frame. The winding device 30 includes a second tooling 31 and a winding machine 32. The winding machine 32 is used to wind copper wire around the base frame positioned in the second tooling 31. The main assembly device 60 includes a third tooling 61, a pushing mechanism 62, and a flat pushing mechanism 63. The third tooling 61 is used to position the base frame wound with copper wire. The pushing mechanism 62 pushes the plate-shaped yoke 104 into the mounting groove 1020 of the frame 102, and the flat pushing mechanism 63 feeds the U-shaped yoke 101 to the frame 102 to form the main frame. The moving iron core pre-assembly device 40 includes a fourth tooling 41, an auxiliary robot 42, and a tightening gun 43. The fourth tooling 41 is used to position the shaft 1 embedded in the core. The moving iron core 1061 of 062 is tightened by a tightening gun 43 mounted on an auxiliary manipulator 42 to tighten the shaft 1062 into the moving iron core 1061. The moving iron core welding device 50 includes a fifth tooling 51 and a welding mechanism 52. The fifth tooling 51 is used to position and drive the connected shaft 1062 and the moving iron core 1061 to rotate synchronously. The welding mechanism 52 is used to weld the connected shaft 1062 and the moving iron core 1061 to form the moving part 106. The finished product pre-assembly device 70 includes a sixth tooling 71 and a second pressing mechanism 72. The sixth tooling 71 is used to support the main frame after it is embedded in the moving part 106. The second pressing mechanism 72 rivets the magnetic shielding sheet 107 located on the main frame onto the main frame. The retaining ring assembly device 80 includes at least a push rod 81. The push rod 81 is used to position the retaining ring 108 on the moving part 106 and abut against the end of the main frame away from the magnetic shielding sheet 107.

[0040] Combination Figure 12 and Figure 13As shown, in this utility model, the electromagnet includes a U-shaped yoke 101, a frame 102, a sleeve 103, a plate-shaped yoke 104, a coil 105, a moving part 106, a magnetic shielding sheet 107, and a retaining ring 108. The specific positional relationship of the above components is as follows: the sleeve 103 is embedded in the frame 102; a pair of plate-shaped yokes 104 are respectively embedded in two mounting slots 1020 located on opposite sides of the frame 102; the coil 105 is wound around the frame 102; the U-shaped yoke 101 is located on the outside of the frame 102; part of the moving part 106 is located inside the sleeve 103 and can move along the axis of the sleeve 103; the other part of the moving part 106 extends out of the sleeve 103 and passes through a guide member (guide ring 1060 and guide ring 1060) positioned on the mounting hole of the U-shaped yoke 101. The U-shaped yoke 101 extends out after the retaining ring 108 assembly. The retaining ring 108 is sleeved on the guide ring 1060, extends out of the sleeve 103 and the mounting hole on the U-shaped yoke 101. The retaining ring 108 and the guide ring 1060 are positioned in cooperation at the mounting hole of the U-shaped yoke 101. The magnetic shielding sheet is installed at the other end of the frame 102. It should be noted that a pair of plate yokes 104 are located in two mounting slots 1020 respectively, and they have a repulsive force on each other. The U-shaped yoke 101 blocks the plate magnet 101, ensuring that the U-shaped plate yoke 101 will not fall out of the mounting slot due to the repulsive force. The plate yoke 104 is attracted to the U-shaped yoke 101 to ensure the installation stability between the U-shaped yoke 101, the frame 102, the sleeve 103 and the plate yoke 104. The specific assembly process of the electromagnet is as follows: First, the sleeve 103 is installed on the frame 102 to form a base frame, and copper wire is wound around the sleeve 103 to form a coil 105. Then, a plate-shaped yoke 104 is inserted into the mounting groove 1020 of the frame 102, and the above-mentioned combined structure is connected with the U-shaped yoke 101 to form a main frame. After the guide ring 1060 is fitted onto the shaft 1062, it is tightened into the moving iron core 1061. The shaft 1062 and the moving iron core 1061 are welded together to form a moving part 106. The guide ring 1060 is not welded. The moving part 106 is embedded into the sleeve 103. Furthermore, the end of the shaft 1062 extends out of the U-shaped yoke 101, the guide ring 1060 abuts against the moving iron core 1061, and the other end can be inserted into the mounting hole of the U-shaped yoke 101. The U-shaped yoke 101 is provided with a protrusion 1011, and the magnetic shielding sheet 107 is provided with a groove 1071 that cooperates with the protrusion 1011. The protrusion 1011 is inserted into the groove 1071. After the protrusion 1011 is riveted, its end extends and covers the magnetic shielding sheet 107, thus connecting them. After fixing the retaining ring 108 onto the guide ring 1060 (the annular groove of the guide ring 1060), the overall assembly is achieved.Based on the above assembly process, the skeleton 102 is positioned on the first positioning fixture 21, and the sleeve 103 is positioned at the output end of the first pressing mechanism 22. The first pressing mechanism 22 moves the sleeve 103 downward and presses the sleeve into the skeleton 102, forming a base frame. The base frame is positioned on the second fixture 31, and copper wire is wound around the outside of the sleeve by the winding machine 32 to form a coil 105. Then, it is positioned on the third fixture 61, and the pushing mechanism 62 pushes the plate yoke 104 into the mounting groove 1020 of the skeleton 102. Mechanism 63 feeds the U-shaped yoke 101 to the connection with the frame 102, and the U-shaped yoke 101 seals the plate-shaped yoke 104 in the mounting groove 1020 to form the main frame. For the forming of the moving part 106, the moving iron core 1061 is first positioned on the fourth tooling 41. The operator puts the guide ring 1060 on the shaft 1062, and with the cooperation of the auxiliary robot arm 42, the operator holds the tightening gun 43 to tighten the shaft 1062 embedded in the moving iron core 1061 into the moving iron core 1061. The tightened moving iron core 1061 and The shaft 1062 is positioned within the fifth tooling 51. While both are rotating, they are welded together via the welding mechanism 52 to form a moving part 106. One end of the moving part 106 with the shaft 1062 is inserted into the sleeve 102 from the unsealed side of the U-shaped yoke 101, causing the shaft 1062 to protrude from the U-shaped yoke 101. The guide ring 1060 can be inserted into the mounting hole of the U-shaped yoke 101. The sealed end of the U-shaped yoke 101 is positioned downwards within the sixth tooling 71, leaving an opening on the U-shaped yoke 101. A magnetic shielding sheet 107 is installed at the end, so that the groove 1071 on the magnetic shielding sheet 107 is nested with the protrusion 1011 on the U-shaped yoke 101. The second pressing mechanism 72 acts on the protrusion 1011 on the U-shaped yoke 101, so that the protrusion 1011 extends and covers the end face of the groove 1071, so that the U-shaped yoke 101 is connected to the magnetic shielding sheet 107. When ensuring that the guide ring 1060 is located in the mounting hole of the U-shaped yoke 101, the push rod 81 is used to put the retaining ring 108 on the guide ring 1060, thereby completing the assembly of the entire electromagnet.

[0041] In this utility model, the forming of corresponding components in the electromagnet and the assembly of the product can be realized by the pressing device 20, the winding device 30, the moving iron core pre-assembly device 40, the moving iron core welding device 50, the main body assembly device 60, the finished product pre-assembly device 70 and the retaining ring assembly device 80, which can improve the assembly efficiency and assembly accuracy of the electromagnet.

[0042] It should be noted that the above-mentioned devices are operated by the operator to perform the corresponding assembly actions. The above-mentioned devices need to be connected in series by the operator. Preferably, a material rack 1000 and a turnover box are set between the above-mentioned devices to hold the corresponding structural parts after the operation of each device is completed, and to transfer the corresponding structural parts.

[0043] like Figure 3 and Figure 4 As shown, in the pressing device 20, the frame 102 is positioned on the first positioning fixture 1021. The first pressing mechanism 22 includes a first pressing cylinder 221 and a first pressing head 222. The first pressing cylinder 221 is mounted on the first bracket 220. The first pressing head 222 is mounted on the output end of the first pressing cylinder 221 via the first mounting plate 2210. The specific structure of the first pressing head 222 includes a pressing column 2221, a spring 2222, and an annular component 2224. The pressing column 2221 is fixed to the first mounting plate 2210. The plate 2210 protrudes downward from the first mounting plate 2210. A pair of pins 2223 are symmetrically arranged on the lower part of the pressure column 2221. A pair of vertical waist holes 2225 are symmetrically arranged on opposite sides of the annular member 2224. The upper part of the annular member 2224 is fitted onto the lower part of the pressure column 2221, and the vertical waist holes 2225 are fitted onto the pins 2223. A spring 2222 is provided on the outer side of the pressure column 2221 between the first mounting plate 2210 and the annular member 2224 to achieve the connection between the pressure column 2221 and the annular member. 2224 can move up and down relative to each other. The lower part of the annular part 2224 is provided with a pair of spring ball plungers 2227 that can extend into the central cavity 2226 of the annular part 2224. When the sleeve 103 is inserted into the central cavity 2226 and abuts against the lower end of the pressure column 2221, the sleeve 103 is positioned and fixed in the lower part of the annular part 2224 by the pair of spring ball plungers 2227. When the sleeve 103 is pressed against the frame 102 by the first pressure head 222, the lower end of the annular part 2224 can abut against the frame 102. Since the pressure column 2221 can move up and down relative to the annular part 2224, the pressure column 2221 can press the sleeve 103 into the frame 102; the first mounting plate 2210 is provided with a first guide 223 (a combination of guide rod and guide cylinder) to guide the lifting and lowering of the first pressure head 222; the first positioning fixture 21 is provided with a limiting plate 211 on the side of the frame 102, and the limiting plate 211 abuts against the first mounting plate 2210 to limit the downward movement distance of the first lower pressure head 222.

[0044] like Figure 5As shown, in the main assembly device 60, the pushing mechanism 62 includes a guide plate 621 and a pushing assembly 622. The guide plate 621 is provided with a guide groove 6211 for supporting the plate-shaped yoke 104. The pushing assembly 622 includes a pushing cylinder 6221 and a pushing plate 6222 disposed at the output end of the pushing cylinder 6221. The pushing plate 6222 is driven to abut against the plate-shaped yoke 104 located in the guide groove 6211 and pushes the plate-shaped yoke 104 into the mounting groove 1020 of the frame 102. The horizontal pushing mechanism 63 includes a translation cylinder 631 and a supporting plate 632 disposed at the output end of the translation cylinder 631. The supporting plate 632 is driven to translate and feed the U-shaped yoke 101 located thereon and position it on the base frame. The operation process of the main assembly device 60 is as follows: First, the push cylinder 6221 drives the push plate 6222 to move, pushing the plate yoke located in the guide groove 6211 into the mounting groove 1020. The guide groove 6211 can support the plate yoke 104 and limit its movement direction. After the U-shaped yoke 104 is installed in place, the push assembly 622 resets, and the translation cylinder 631 drives the support plate 632 to move, covering the U-shaped yoke 101 on the outside of the base frame (except for the bottom of the base frame) and sealing the plate yoke 104, thereby forming the main frame. Preferably, the support plate 632 is provided with a positioning notch 6321 that matches the protrusion 1011 of the U-shaped yoke 101. When the support plate 632 supports the U-shaped yoke 101, the positioning notch 6321 makes way for the protrusion 1011.

[0045] like Figure 6 As shown, in the moving iron core pre-assembly device 40, the fourth tooling 41 includes a positioning block 411 and a pair of clamping assemblies 412 respectively disposed on opposite sides of the positioning block 411. The positioning block 411 is provided with a positioning groove for positioning the moving iron core 1061. The clamping assembly 412 includes a clamping cylinder 4121 and a clamping plate 4122 disposed at the output end of the clamping cylinder 4121. The pair of clamping plates 4122 are driven to abut against the side wall of the moving iron core 1061 located on the positioning block 411 for clamping the moving iron core 1061. After the moving iron core 1061 is clamped, it remains in a fixed state, which facilitates the tightening gun to rotate and tighten the shaft 1062 located inside it (the guide ring 1060 is first sleeved on the shaft 1062 before the moving iron core 1061 and the shaft 1062 are rotated and tightened), thus forming a state in which the shaft 1062 is tightened on the moving iron core 1061 and the guide ring 1060 is sleeved on the shaft 1062; in addition, the clamping plate 4122 is provided with a contour groove that matches the side wall of the moving iron core 1061, which can achieve a more stable clamping of the moving iron core 1061.

[0046] like Figure 7As shown, in the moving iron core welding device 50, the fifth tooling 51 includes a support assembly 511 and a rotary drive assembly 512. The support assembly 511 includes a lifting cylinder 5111, a lifting block 5112, and a rotating block 5113. The lifting cylinder 5111 is mounted on the second bracket 5110, the lifting block 5112 is mounted on the output end of the lifting cylinder 5111, and the rotating block 5113 is rotatably mounted on the lifting block 5112 and has a positioning groove for positioning the end of the shaft 1062 away from the moving iron core 1061. The rotary drive assembly 512 includes a rotary motor 5121 and a gripper 5122. The rotary motor 5121 is mounted on the third bracket 5120, and the gripper 5122 is mounted on the output end of the rotary motor 5121 for gripping the end of the moving iron core 1061 away from the shaft 1062. When using the fifth tooling 51, the end of the shaft 1062 away from the moving iron core 1061 is first positioned... One end is positioned on the rotating block 5113. At this time, the guide ring 1060 will move down and abut against the rotating block 5113, away from the connection position of the shaft 1062 and the moving iron core 1061. The lifting cylinder 5111 drives the lifting block 5112 and the rotating block 5113 to move up. After moving up to the set position, the end of the moving iron core 1061 away from the shaft 1062 is clamped by the gripper 5122. The rotary motor 5121 drives the moving iron core 1061 and the shaft 1062 to rotate synchronously. The welding mechanism 52 includes a first translation electric cylinder 521 and a welding torch 522 set at the output end of the first translation electric cylinder 521. The welding torch 522 is driven to weld the connection between the shaft 1062 and the moving iron core 1061. Since the shaft 1062 and the moving iron core 1061 rotate synchronously, the entire connection can be welded. After welding, the guide ring 1060 and the shaft 1062 can move relative to each other.

[0047] like Figure 8 As shown, in the pre-assembly device 70, the second pressing mechanism 72 includes a second pressing cylinder 721, a second pressing head 722, and a pre-pressing component 724. The second pressing cylinder 721 is mounted on the fourth bracket 720. Multiple second pressing heads 722 are mounted on the output end of the second pressing cylinder 721 via a second mounting plate 7210. The protrusions 1011 of the U-shaped yoke 101 are covered on the magnetic shielding sheet 107. The second mounting plate 7210 is provided with a second guide component 723 (a combination of a guide rod and a guide cylinder). The pre-pressing member 724 (a combination of spring and pressure plate) is set on the second mounting plate 7210 to guide the lifting and lowering of the second pressure head 722. It is used to press down the magnetic shielding sheet 107. During the process of the second pressure head 722 being driven to move down, the pre-pressing member 724 can position the magnetic shielding sheet 107 on the U-shaped yoke 101 in the sixth tooling 71, ensuring that the position of the magnetic shielding sheet 107 and the U-shaped yoke 101 is relatively stable, and then the second pressure head 722 can rivet the protrusion 1011 of the U-shaped yoke 101.

[0048] like Figure 9As shown, in the retaining ring assembly device 80, in addition to the push rod 81, an auxiliary fixture 82 may also be included. After the magnetic shielding sheet 107 is assembled, the whole assembly is placed in the auxiliary fixture 82 for positioning. The operator moves the shaft 1062 upward, driving the guide ring 1060 and the moving iron core 1061 upward until the guide ring 1060 abuts against the mounting hole of the U-shaped yoke 101. The operator then holds the push rod 81 to assemble the retaining ring 108 into the corresponding position on the guide ring 1060 (in the annular groove on the upper part of the guide ring 1060). And it abuts against the sealed end portion on the U-shaped yoke 101; preferably, a receiving groove 810 can be provided on the push rod 81. In use, the retaining ring 108 abuts against the sealed end portion on the U-shaped yoke 101 and is opposite to the annular groove of the guide ring 1060. The push rod 81 abuts against the retaining ring 108, so that the side of the retaining ring 108 away from its opening is embedded in the receiving groove 810.
