Description

Technical Field

[0001] This invention relates to magnet assembly and production technology, and in particular to a magnet alignment device. Background Technology

[0002] Before magnetizing magnets, they need to be neatly arranged and fixed for batch magnetization. For example, the "Component Arrangement Machine" disclosed in Chinese Patent Document CN204211042U has a swaying mechanism on the upper part of the overall support frame, with a swaying power mechanism driving and connecting to the swaying mechanism; a vibration platform is set at the upper end of the overall support frame, with linear optical shaft seats on both sides of the upper end face of the vibration platform, each housing a linear optical shaft, and a working platform is movably mounted on the linear optical shaft seats; symmetrical crankshaft fixing blocks are set on the vibration platform between the linear optical shaft seats, and a crankshaft rotor is installed between the crankshaft fixing blocks, with the crankshaft rotor driving and connecting to a crankshaft motor, which is mounted on the overall support frame; the machine uses vibration and swaying forces to perform left-right movement and also back-and-forth reciprocating swaying motion, greatly improving work efficiency.

[0003] For example, the "Combined Tabletop-Type Alignment Device" disclosed in Chinese Patent Document CN211444023U includes a frame, alignment machines, and a control panel. The frame is equipped with a worktable and a control panel. Several alignment machines are sequentially installed on the worktable. The alignment mechanism includes a double-stroke cylinder, a bracket, and a pin. The double-stroke cylinder is installed on the frame below the worktable and is arranged horizontally. The upper part of the bracket is equipped with the material trough of the alignment machine, and the lower part is hinged to the piston rod of the double-stroke cylinder through the pin. This achieves the effects of forward swinging, horizontal swinging, and backward swinging during the alignment process of the alignment machine, thereby improving production efficiency.

[0004] For example, the "NdFeB Magnetic Sheet Magnetizing and Positioning Fixture" disclosed in Chinese Patent Document CN214476749U has an upper positioning plate and a lower positioning plate, with a magnetizing positioning plate between the upper and lower positioning plates. The magnetizing positioning plate includes a middle positioning plate, a left side plate, and a right side plate. The upper and lower ends of the middle positioning plate, the left side plate, and the right side plate are respectively connected to the upper positioning plate and the lower positioning plate. There is one middle positioning plate, and at least two left and right side plates are symmetrically arranged on both sides of the middle positioning plate. The middle positioning plate, the left side plate, and the right side plate are joined together to form a positioning plate group with a near-circular cross-section. The sides of the middle positioning plate, the left side plate, and the right side plate have at least three strip grooves with openings at both the upper and lower ends. The strip grooves are arranged in parallel to each other, and NdFeB magnetic sheets stacked vertically are placed in the strip grooves.

[0005] The aligning and magnetizing equipment disclosed in the aforementioned patent documents has the problem of inconvenience in picking up, placing, and transferring the aligning plates, resulting in low efficiency in the process of transferring and disassembling the aligning plates, which urgently needs to be improved.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0029] like Figures 1 to 10 In the embodiment of the magnet aligning device of the present invention shown, a vibrating base plate 11 is installed on the workbench 10 of the magnet aligning device. A vibrating groove 20 is provided on the vibrating base plate 11. A slot 201 for accommodating the aligning plate 30 is provided at the bottom of the vibrating groove 20. The upper surface of the aligning plate 30 is provided with uniformly arranged magnet receiving slots 301. A clamping mechanism 202 for clamping and fixing the aligning plate 30 within the vibrating groove 20 is also provided on the vibrating groove 20. The upper surface of the aligning plate 30 is also provided with a plurality of oblong-shaped locking posts 31. The long side of the plate is parallel to the long side of the column plate 30. The bottom of the multiple pins 31 is provided with an opening slot 311 arranged in the same direction. The upper surface of the column plate 30 is also provided with a detachable cover plate 32. The cover plate 32 is provided with a card hole 33 corresponding to the pin 31. The cross-section of the card hole 33 is oblong and the long side of the card hole 33 is larger than the long side of the pin 31. The lower surface of the cover plate 32 is also provided with a card plate 331 located in the card hole 33. After the pin 31 is inserted into the card hole 33 from bottom to top, the cover plate 32 can be moved to make the card plate 331 engage in the slot 311.

[0030] This application, by setting a locking post and a detachable cover plate on the alignment plate, allows the cover plate to be locked onto the upper surface of the alignment plate after the vibration groove vibrates with the vibration base plate to fill all the magnet receiving slots on the alignment plate with magnets. This facilitates the transfer of the alignment plate and effectively prevents the magnets from falling out of the magnet receiving slots during the transfer process. This improves the efficiency of transferring and disassembling the alignment plate during magnet alignment and magnetization.

[0031] In the above embodiments of this application, such as Figures 1 to 4 As shown, the clamping mechanism 202 can clamp and fix the entire plate 30 in the slot 201 at the bottom of the vibration groove 20. Activating the vibration assembly inside the worktable 10 causes the vibration base plate 11 to vibrate and swing. The structure of the vibration assembly inside the worktable 10 can be referred to the prior art shown in the background section of this application, and will not be repeated here. After the vibration groove vibrates with the vibration base plate, filling all the magnet receiving slots on the entire plate with magnets, as... Figure 6As shown, the cover plate 32 is moved to the left so that the left and right sides of the cover plate 32 are aligned with the left and right sides of the array plate 30. Then the cover plate is moved down so that the locking pin 31 on the array plate 30 is inserted into the corresponding locking hole 33 from bottom to top. Then the cover plate is moved so that the locking plate 331 is inserted into the locking slot 311. This allows the cover plate to be installed quickly. The cover plate can prevent the magnet from coming out of the magnet receiving slot on the upper surface of the array plate.

[0032] In one embodiment of this application, preferably, the vibration groove 20 includes two side plates 21 and two top plates 22, with the two top plates 21 located between the two side plates 22. A clamping plate 23 is also provided at the bottom of the top plate 22. Preferably, one top plate 22 is fixedly connected to the vibration base plate 11, and the other top plate 22 is fixedly connected to the movable end of the clamping mechanism 201. Thus, the clamping mechanism 201 allows the two top plates 22 to clamp the entire row of plates in the slot 311, making it convenient to lock and unlock the entire row of plates and facilitating their placement and removal. Preferably, the clamping plate 23 is also provided with a turning groove 231. When the vibration groove 20 vibrates with the vibration base plate 11, the magnetic particles entering the turning groove 231 vibrate with the vibration groove. The magnetic particles can tumble faster as they enter and exit the turning groove, allowing their posture to adjust before vibrating with the vibration groove and sliding back towards the entire row of plates. By providing the turning groove, the efficiency of filling the magnetic receiving slot with magnetic particles can be improved.

[0033] In one embodiment of this application, preferably, the magnet aligning device further includes a magnetizing fixing frame 40, which includes an upper support plate 41, a lower support plate 42, and two connecting plates 43. An aligning plate receiving area is formed between the upper support plate 41 and the lower support plate 42, and multiple aligning plates 30 parallel to the connecting plates 43 can be placed in the aligning plate receiving area. The upper support plate 41 has a threaded hole at its center, and a pressure rod 50 is installed in the threaded hole. The outer wall of the pressure rod 50 has an external thread, and the lower end of the pressure rod 50 extends downward into the aligning plate receiving area and is fitted with a pressure plate 51. When the pressure rod 50 rotates, the pressure plate 51 can move downward in the aligning plate receiving area to press the upper end of the aligning plate 30. This application provides a rotatable pressure rod on the upper support plate, and the lower end of the pressure rod is provided with a pressure plate. By rotating the pressure rod, the aligning plate placed between the two connecting plates can be quickly clamped by the pressure plate, thereby quickly locking and unlocking the aligning plate, making the installation and disassembly of the aligning plate convenient.

[0034] In one embodiment of this application, preferably, the pressure plate 51 is rotatably mounted on the lower end of the pressure rod 50, and the magnetizing fixing frame 40 is also provided with a limiting structure to prevent the pressure plate 51 from rotating relative to the magnetizing fixing frame 40. This ensures that when the pressure rod 50 drives the pressure plate to move downward, the pressure plate will not rotate relative to the entire row of plates, making the clamping and locking of the pressure plate relative to the entire row of plates reliable. Specifically, the limiting structure can be designed as needed; in one embodiment, a vertical groove can be opened on the inner side of the connecting plate 43, and a protrusion extending into the vertical groove can be provided on the pressure plate 51, so that the pressure plate can only move up and down, thereby preventing the pressure plate 51 from rotating relative to the side plate; in another embodiment, an upwardly extending guide rod can be provided on the upper surface of the pressure plate 51, and a guide hole that cooperates with the guide rod can be provided on the upper support plate 41. The guide rod passes through the guide hole, so that the pressure plate can only move up and down.

[0035] In one embodiment of this application, preferably, a circular connecting plate 52 is fixed to the lower end of the pressure rod 50, the central axis of the connecting plate 52 coincides with the central axis of the pressure rod 50, and the pressure plate 51 is rotatably mounted on the connecting plate 52; preferably, the pressure plate 51 includes an upper pressure plate 511 and a lower pressure plate 512, the center of the upper pressure plate 511 is provided with a mounting hole adapted to the pressure rod 50, and the center of the lower pressure plate 512 is provided with a mounting groove adapted to the connecting plate 52, and the upper pressure plate 511 and the lower pressure plate 512 are fixedly connected by screws; thereby making the pressure plate 51 reliably installed at the lower end of the pressure rod 50.

[0036] In one embodiment of this application, preferably, the outer contour of the pressure plate 51 is oblong, the long side of the pressure plate 51 is parallel to the connecting plate 43, and the distance between the two connecting plates 43 is less than the length of the long side of the pressure plate 51, thereby preventing the pressure plate 51 from rotating between the two connecting plates. The connecting plate is a limiting structure to prevent the pressure plate from rotating. Preferably, the length of the short side of the pressure plate 51 is equal to the distance between the two connecting plates 43, and the connecting plate constitutes a limiting structure to prevent the pressure plate from rotating, so that the pressure plate can only move up and down between the two connecting plates.

[0037] In one embodiment of this application, preferably, the lower support plate 42 is provided with a plurality of vertical through slots 421, and the connecting plate 43 is provided with a plurality of vertical holes 431, thereby reducing the weight of the magnetizing bracket and improving the heat dissipation effect.

[0038] In one embodiment of this application, preferably, the upper end of the pressure rod 50 is also provided with a handle 53, which is elliptical in shape, thereby facilitating the rotation of the pressure rod 50 by the handle 53, so that the pressure rod 50 can move up and down along the threaded hole in the center of the upper support plate 41.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
