Description

Technical Field

[0001] This utility model relates to the field of insulated magnet assembly technology, specifically to an insulated magnet assembly device. Background Technology

[0002] In fields such as new energy vehicles, industrial motors, and precision instruments, insulated magnet assemblies are core components, and their assembly quality directly affects the operating efficiency, stability, and service life of the equipment. Insulated magnet assemblies typically consist of multiple parts, including magnets, insulating sheets, and positioning brackets. The assembly precision requirements between these components are extremely high, especially the fit and relative positional deviation between the magnets and the insulating sheets, which must be strictly controlled within the micrometer range to avoid problems such as magnetic flux loss and decreased insulation performance due to improper assembly. Currently, the assembly of insulated magnet components is mostly done manually or semi-automatically. When assembling manually, operators need to use simple tools to complete the magnet assembly, which is not only labor-intensive and inefficient, but also prone to poor product consistency due to human error, making it difficult to meet the needs of mass production. Current automated assembly methods involve first applying adhesive to the inner wall of the rotor housing insulation layer using a dispensing device, then inserting the rotor housing into the circumferentially distributed magnets. During insertion, the adhesive is displaced, resulting in a thin or even nonexistent adhesive layer. This compromises stable bonding strength and poses a risk of magnet loosening or detachment. Accumulated adhesive can also create air bubbles or gaps due to internal stress, reducing the integrity of the insulation layer, leading to unstable insulation performance, and potentially causing localized breakdowns during subsequent use, thus affecting the safe operation of the entire assembly. To address these shortcomings, we propose an insulated magnet assembly device. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly device for insulated magnet components to solve the problems mentioned in the background art. In the current automated assembly, after the rotor housing is glued to the outer wall, when it is fitted into the inside of the magnet, the glue displacement causes the glue layer to be too thin or there is no glue, making the magnet easy to loosen; the accumulation of glue causes air bubbles, which reduces insulation and may break down, affecting safe operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An insulated magnet assembly device includes a rotor magnet assembly workbench, a support plate connected to the top of one side of the assembly workbench, a lead screw module connected to the outer wall of the support plate near the assembly workbench, a rotor housing fixing component located at the bottom of the lead screw module, and assembly parts for assembling magnets located on both sides of the rotor housing fixing component and on the top of the assembly workbench.

[0005] Preferably, the assembly includes a fixed base plate, an electric telescopic rod, an electromagnet, and a magnetic steel tile receiving plate for accommodating the magnetic steel tile. The bottom of the fixed base plate is fixed to the assembly workbench on one side of the rotor housing fixing component via a horizontal displacement guide rail module. The horizontal displacement guide rail module is perpendicular to the fixed base plate. The electric telescopic rod is installed parallel to the fixed base plate. The magnetic steel tile receiving plate is an arc-shaped structural plate with a concave inner wall and a convex outer wall. The outer wall of the magnetic steel tile receiving plate is connected to the output end of the electric telescopic rod. The electromagnet is embedded inside the magnetic steel tile receiving plate and is connected to a power supply device via a wire.

[0006] Preferably, the rotor housing fixing component includes an assembly rotary motor, a shaft, and a fixing base. The fixing base is arranged in an inverted T-shape and is installed on the top of the assembly workbench. The shaft is installed on the bottom of the fixing base, and the assembly rotary motor is installed on the bottom of the assembly workbench. The top output end of the assembly rotary motor passes through the fixing base and is connected to the bottom of the shaft.

[0007] Preferably, a receiving component for accommodating the magnet tiles is provided on the assembly worktable located on one side of the rotor housing fixing component. The receiving component includes a receiving ring and a receiving plate. The receiving ring is arranged in a ring structure. The receiving ring has a through arc-shaped receiving groove for the magnet tiles on the assembly components near both sides. The receiving plate is connected through to the top of each arc-shaped receiving groove of the magnet tiles. Multiple magnet tiles are arranged in an arc structure inside the arc-shaped receiving groove of the magnet tiles.

[0008] Preferably, the magnetic steel tile receiving plate and the magnetic steel tile arc-shaped receiving groove each receive one-quarter of the outer circumferential wall of the rotor housing.

[0009] Preferably, a dispensing head is installed at the bottom output end of the lead screw module, and the dispensing head is located directly above the rotor housing fixing component.

[0010] This utility model has the following beneficial effects: 1. This application effectively solves the problem of adhesive displacement and improves assembly reliability. The device employs an external wall-attachment assembly logic for the components, utilizing the arc-shaped structure of the magnet tile receiving plate in conjunction with the precise pushing of the electric telescopic rod to radially adhere the magnet tile to the outer wall of the rotor shaft housing. During this process, the adhesive is mainly subjected to radial pressure, significantly reducing shear force. This greatly reduces the phenomenon of adhesive being "carried away" or accumulating, ensuring uniform adhesive layer thickness and stable bonding strength between the magnet and the rotor shaft housing. It also reduces the risk of magnet loosening or detachment, while avoiding the problem of decreased insulation performance caused by air bubbles or gaps due to adhesive accumulation.

[0011] 2. The symmetrical magnetic steel tile receiving plates on both sides can simultaneously attach the magnetic steel tiles to each quarter circumference of the rotor housing. The assembly of half a circumference can be completed in one operation. Then, by driving the rotor shaft housing to rotate 180° through the fixed base, the assembly of the remaining half circumference can be completed. This reduces the number of rotations and operation steps, significantly improves assembly efficiency, and can better meet the needs of mass production. 3. The symmetrical magnet tile receiving plates on both sides maintain structural consistency, ensuring the symmetry of the magnet tiles assembled on both sides in terms of position and angle. During the 180° rotation of the rotor shaft housing driven by the fixed base, its stable rotational accuracy ensures precise alignment between the remaining assembly position and the magnet tile receiving plate after rotation. This avoids the cumulative errors that may occur from multiple rotations, thus guaranteeing the overall accuracy of the magnet tile assembly on the entire rotor shaft housing and contributing to improved product performance stability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0020] Please see the appendix Figures 1-5As shown, an insulated magnet assembly device includes a rotor-magnet assembly workbench 1. A support plate 2 is connected to the top of one side of the assembly workbench 1. A lead screw module 3 is connected to the outer wall of the support plate 2 near the assembly workbench 1. The assembly workbench 1 serves as a base platform, and the lead screw module 3 is fixed to one side via the support plate 2, forming a vertical motion mechanism. The modular design facilitates equipment integration and maintenance. A vision inspection instrument and a data processor connected to control equipment are installed on the lead screw module 3. The vision inspection instrument is fixed to the outer wall of the lead screw module 3 by a bracket, with its lens facing the rotor housing fixing component 4. The data processor is electrically connected to the vision inspection instrument and can perform real-time analysis and feedback on parameters such as the positional accuracy and fit of the assembled magnet. A rotor is located on the assembly workbench 1 at the bottom of the lead screw module 3. The rotor housing fixing component 4 has a glue dispensing head installed at the bottom output end of the lead screw module 3. The glue dispensing head is located directly above the rotor housing fixing component 4. The rotor housing fixing component 4 includes an assembly rotary motor 41, a shaft 42, and a fixed base 43. The fixed base 43 is arranged in an inverted T-shape and is installed on the top of the assembly workbench 1. The shaft 42 is installed at the bottom of the fixed base 43, and the assembly rotary motor 41 is installed at the bottom of the assembly workbench 1. The top output end of the assembly rotary motor 41 passes through the fixed base 43 and connects to the bottom of the shaft 42. The rotor housing fixing component 4 uses a T-shaped fixed base 43 and an assembly rotary motor 41. The shaft 42 enables precise positioning and 180° rotation of the rotor housing. The motor drives the shaft 42 to rotate the rotor housing at a uniform speed, which, together with the side fittings 5, completes the segmented magnetic steel tile bonding.On the top of the assembly workbench 1 on both sides of the rotor housing fixing component 4, there are assembly parts 5 for assembling magnets. The assembly parts 5 include a fixed base plate 51, an electric telescopic rod 52, an electromagnet 53, and a magnet tile receiving plate 54 for accommodating the magnet tiles. The bottom of the fixed base plate 51 is fixed to the assembly workbench 1 on one side of the rotor housing fixing component 4 by a horizontal displacement guide rail module 55. The horizontal displacement guide rail module 55 is perpendicular to the fixed base plate 51. The electric telescopic rod 52 is installed parallel to the fixed base plate 51. The magnet tile receiving plate 54 is an arc-shaped structural plate with a concave inner wall and a convex outer wall. The outer wall of the magnet tile receiving plate 54 is connected to the output end of the electric telescopic rod 52. The electromagnet 53 is embedded in the magnet tile receiving plate 54 and is connected to the power supply via a wire. When the electrical equipment is connected, the horizontal displacement guide rail module 55 moves the magnetic steel tile receiving plate 54 to the material picking position of the receiving part 6. The control equipment controls the electromagnet 53 to be energized. At this time, the magnetic steel tile receiving plate 54 generates magnetic force. The electric telescopic rod 52 drives the magnetic steel tile receiving plate 54 to move, electro-adsorbing a quarter-circumferential magnetic steel tile. At this time, the horizontal displacement guide rail module 55 moves the magnetic steel tile receiving plate 54 to both sides of the rotor housing fixing part 4, placing the rotor housing on the fixed base 43. The electric telescopic rod 52 pushes the magnetic steel tile radially to achieve precise contact with the inner wall of the rotor housing. After the magnetic steel tile contacts the adhesive, it is held for 3 seconds. The electromagnet 53 is de-energized, the assembly part 5 returns to the initial position, and the rotor housing fixing part 4 rotates 180°. The above bonding process is repeated to complete the assembly of the remaining half-circumferential magnetic steel tile.

[0021] Before assembly, the rotor housing to be assembled is placed on the fixed base 43. The control device drives the lead screw module 3 to move the bottom dispensing head to the outer wall of one side of the rotor housing. At this time, the dispensing head dispenses glue. The assembly rotary motor 41 drives the fixed base 43 and the rotor housing above it to rotate, dispensing glue onto the outer wall of the rotor housing. The horizontal displacement guide rail module 55 drives the fixed base plate 51 and the magnetic steel tile receiving plate 54 to move to the receiving part picking position. The control device triggers the electromagnet 53 to be energized, and the magnetic steel tile receiving plate 54 generates magnetic force. The electric telescopic rod 52 pushes the receiving plate close to the magnetic steel tile, adsorbing a set of quarter-circumference magnetic steel tiles. Subsequently, the horizontal displacement guide rail module 55 drives the receiving plate with the adsorbed magnetic steel tiles to the assembly positions on both sides of the rotor housing to complete the positioning. The electric telescopic rod 52 pushes the magnetic steel tile receiving plate 54 radially at a uniform speed, so that... The magnetic steel tile is precisely bonded to the adhesive application area on the inner wall of the rotor housing; the bonded state is maintained for 3 seconds to ensure full contact between the adhesive and the magnetic steel tile and the rotor housing; then the electromagnet 53 is de-energized to release the magnetic steel tile, and the electric telescopic rod 52 drives the receiving plate to retract, completing the assembly of the magnetic steel tile for half a circumference (one-quarter on each side) of the rotor housing. The assembly rotary motor 41 drives the shaft 42 to rotate the rotor housing 180°, aligning the half circumference without the magnetic steel tile with the two side fittings 5; the material picking, positioning and bonding process of steps 3-4 is repeated to complete the assembly of the remaining half circumference of the magnetic steel tile. The vision inspection instrument on the lead screw module 3 takes pictures of the assembled magnetic steel components, and the data processor analyzes the positional accuracy, bonding degree and adhesive layer distribution of the magnetic steel tile in real time. If it is qualified, a completion signal is output; if it is unqualified, an alarm is triggered, realizing full-process quality monitoring.

[0022] This application uses "radial bonding" instead of the traditional "axial insertion". The shear force on the adhesive is reduced during the assembly of the magnetic steel tile, avoiding problems such as the adhesive layer being too thin, no adhesive, or accumulation caused by the adhesive being "taken away". With the precise control of the adhesive by the dispensing head, the thickness deviation of the adhesive layer is small and the bonding strength is high, which completely solves the problems of the risk of loosening and falling off of the magnetic steel and the unstable insulation performance.

[0023] The two-sided assembly of the five parts can be carried out simultaneously. A single bonding can complete the semi-circular assembly, and the 180° rotation can achieve the full-circular assembly, shortening the assembly cycle of a single component. The automated material picking, bonding, and inspection process requires no manual intervention, reducing the labor intensity of operators and adapting to the needs of mass production.

[0024] The embedded design of the electromagnet 53 ensures that the magnetic steel tile is firmly attached, preventing it from falling off during the material handling process; the arc-shaped structure of the magnetic steel tile receiving plate 54 perfectly matches the inner wall of the rotor housing, eliminating local compression during bonding and reducing the risk of damage to the magnetic steel tile; the modular design of the support plate, lead screw module and accessories facilitates equipment maintenance and upgrades, reducing later operation and maintenance costs.

[0025] Please see the appendix Figure 4 and Figure 5As shown, an assembly workbench 1 located on one side of the rotor housing fixing component 4 is provided with a receiving component 6 for accommodating the magnet tiles. The receiving component 6 includes a receiving ring 61 and a receiving plate 62. The receiving ring 61 is arranged in a ring structure, and an arc-shaped receiving groove 611 for the magnet tiles is opened through the receiving ring 61 near the two side assembly components 5. The receiving plate 62 is connected through to the top of each arc-shaped receiving groove 611 for the magnet tiles. Multiple magnet tiles are arranged in an arc structure inside the arc-shaped receiving grooves 611 for the magnet tiles. The magnet tiles accommodated by the magnet tile receiving plate 54 and the arc-shaped receiving grooves 611 for the magnet tiles are all The quarter-circumferential wall of the rotor housing, the receiving plate 62, plays a limiting and guiding role for the magnetic steel tiles in the arc-shaped receiving groove 611 of the magnetic steel tile, ensuring that the magnetic steel tiles maintain an arc-shaped arrangement in the groove and will not be deviated due to external force or their own magnetism. When the assembly 5 needs to pick up materials, the horizontal displacement guide rail module 55 drives the magnetic steel tile receiving plate 54 to move to the receiving part 6. At this time, the arc-shaped structure of the magnetic steel tile receiving plate 54 matches the arc shape of the arc-shaped receiving groove 611 of the magnetic steel tile. The electromagnet 53 is energized to generate magnetic force, which can accurately attract the magnetic steel tiles that are neatly arranged in the quarter-circumference of the groove.

[0026] During operation, the operator first places the magnetic steel tiles into the pre-set arc-shaped receiving groove 611 in sequence. The receiving plate 62 will standardize the placement of the magnetic steel tiles to ensure their accurate position. Then, the magnetic steel tile receiving plate 54 of the assembly 5 moves to the material picking position to complete the adsorption and picking of the magnetic steel tiles, and then pushes the magnetic steel tiles to the rotor housing for assembly. The combination of the arc-shaped receiving groove 611 and the receiving plate 62 in this application ensures that the magnetic steel tiles maintain a precise arc-shaped arrangement before being picked up, reducing the positioning adjustment time during picking and improving picking efficiency. Secondly, since the capacity of both the arc-shaped receiving groove 611 and the receiving plate 54 is one-quarter of the outer circumferential wall of the rotor housing, and their arc-shaped structures match, the picking process is smoother, preventing collisions or falls of the magnetic steel tiles during picking and reducing the damage rate. Furthermore, the receiving component 6 enables centralized storage and orderly supply of the magnetic steel tiles. Combined with the automated picking of the assembly component 5, it reduces manual intervention, further improving the automation and stability of the entire assembly process, laying a solid foundation for the subsequent precise assembly of the rotor housing and the magnetic steel tiles. It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
