Rotor magnet pasting assembly mechanism capable of preventing glue scratch

Abstract

A rotor magnet-pasting assembly mechanism capable of preventing glue scratching, comprising an assembly component, a jig component and a whole-circle heating component. The assembly component pushes the magnet steel out of the adsorption jig through a pressing rod. The upper end of the magnet steel bearing ring through hole of the jig component is provided with a first extension section, and the lower end of the adsorption jig is provided with a second extension section, which are respectively used as the inner side blocking surface of the upper and lower ends of the magnet steel. In the process of magnet steel descending and pasting, the two extension sections continuously limit and block the inner side wall of the magnet steel, and cooperate with the pressing force of the pressing rod to prevent the magnet steel from being adsorbed in advance due to the increase of magnetic force. At the same time, the annular gap between the magnet steel bearing ring and the base column provides a containing space for the glue, so that the magnet steel will not be positionally deviated due to early adsorption, and will not contact or hang with the glue on the surface of the rotor iron core in the whole process of descending and pasting, thereby completely avoiding the problems of glue scratching, extrusion or pollution, and improving the magnet-pasting assembly yield and product performance.

Description

Technical Field

[0001] This invention relates to the field of rotor core manufacturing equipment technology, and in particular to a rotor magnetic bonding assembly mechanism that prevents glue scratching. Background Technology

[0002] In the field of motor manufacturing, especially in the production of permanent magnet motors, the precise and efficient mounting of magnets onto the outer surface of the rotor core is a crucial process. Traditional magnet mounting processes are mostly completed manually or with semi-automated equipment, resulting in low efficiency, poor consistency, and a tendency for missed or misaligned magnets. Furthermore, due to the strong magnetism of the magnets themselves, multiple magnets are prone to sticking together and difficult to separate during automated feeding and mounting processes, further increasing the difficulty of process control.

[0003] Most existing technologies employ a method of bonding individual magnets one by one. While this can control the bonding posture of individual magnets to some extent, the assembly cycle is slow and the production efficiency is extremely low, making it difficult to meet the needs of large-scale mass production. Existing technologies have also attempted to simultaneously press a whole ring of magnets onto the rotor core. However, due to the strong magnetism of the magnets themselves, they are prone to premature adsorption during the synchronous approach of the entire ring to the rotor core. Furthermore, the gap between the inner wall of the magnet and the surface of the rotor core is very small during the pressing process, lacking effective space to avoid the adhesive. This causes the magnets to directly scrape the pre-coated adhesive during the pressing process or when prematurely adsorbed, resulting in insufficient adhesive or even adhesive being squeezed out of the bonding surface, affecting the final bonding strength. Summary of the Invention

[0004] In view of this, the present invention provides a rotor magnetizing assembly mechanism that prevents glue scratching, so as to solve the above-mentioned technical problems.

[0005] A rotor magnetizing assembly mechanism to prevent glue scratching includes an assembly assembly and a fixture assembly. The assembly assembly includes an adsorption fixture, a first cylinder, a first movable plate disposed on the output end of the first cylinder, and a pressure rod disposed on the first movable plate. Multiple partition plates are circumferentially spaced on the outer wall of the adsorption fixture, forming a receiving station between adjacent partition plates. Each receiving station contains an adsorption block, and the magnet can be adsorbed onto the adsorption block. The pressure rod abuts against the top of the magnet and pushes it. The fixture assembly includes a frame, a base column disposed on the frame, a first positioning block disposed on the base column, a second cylinder disposed on the frame, a second movable plate disposed on the output end of the second cylinder, a connecting rod disposed on the second movable plate, a third movable plate disposed on the connecting rod, and a magnet bearing ring disposed on the third movable plate. The rotor core is sleeved on the first positioning block. Both the third moving plate and the magnetic steel bearing ring have through holes at their centers. The inner diameter of the through hole is larger than the outer diameter of the base column, so that the third moving plate and the magnetic steel bearing ring are coaxially spaced on the outside of the base column. The upper end of the through hole of the magnetic steel bearing ring extends upward along the axial direction to form a first extension section. The first extension section serves as the inner blocking surface of the lower end of the magnet. The outer side wall of the adsorption fixture facing the fixture assembly extends downward along the axial direction to form a second extension section. The second extension section serves as the inner blocking surface of the upper end of the magnet. After the magnet is pushed out of the adsorption fixture by the pressure rod, the lower end of the magnet abuts against the magnetic steel bearing ring, and the upper end is pressed by the pressure rod. The inner side walls of the upper and lower ends of the magnet are respectively in close contact with the first extension section and the second extension section. During the synchronous descent of the magnet driven by the magnetic steel bearing ring and the adsorption fixture, the first extension section and the second extension section limit and block the inner side wall of the magnet.

[0006] Furthermore, the assembly assembly also includes a first multi-axis moving device, a mounting plate disposed on the first multi-axis moving device, a rotary motor disposed on the mounting plate, and a rotary connecting shaft disposed on the output end of the rotary motor. The first multi-axis moving device is used to drive the mounting plate to move in multiple axes. The output end of the rotary motor is connected to the adsorption fixture through the rotary connecting shaft and is used to drive the adsorption fixture to rotate in increments around its central axis.

[0007] Furthermore, a plurality of pressure rods are fixed on the first movable plate. The number of pressure rods is consistent with the number of accommodating stations on the adsorption fixture, and their positions correspond one-to-one. Each pressure rod is located above the gap between two adjacent partition plates, and the size of the pressure rod is smaller than the distance between two adjacent partition plates.

[0008] Furthermore, the first positioning block is provided with three clearance grooves at intervals, and the clearance grooves are connected to the outer side wall of the first positioning block.

[0009] Furthermore, four connecting rods are provided and located at the four corners of the second and third moving plates, respectively. One end of each connecting rod is connected to the second moving plate, and the other end is connected to the third moving plate. The second moving plate is connected to the third moving plate via the four connecting rods.

[0010] Furthermore, the anti-adhesive scratching rotor magnetizing assembly mechanism also includes a round heating assembly, which includes a second multi-axis moving device, a clamping device disposed on the second multi-axis moving device, a second positioning block, two third cylinders respectively located on both sides of the second positioning block, two shaping blocks respectively disposed on the two third cylinders, a third multi-axis moving device, a pressing block disposed on the third multi-axis moving device, and a heating device disposed on the third multi-axis moving device.

[0011] Furthermore, the second multi-axis moving device is used to drive the clamping device to move in multiple axes, so as to control the clamping device to transfer the rotor core equipped with the magnet on the fixture assembly to the second positioning block. The clamping device is a three-jaw cylinder.

[0012] Furthermore, the structure of the second positioning block is the same as that of the first positioning block.

[0013] Furthermore, the two third cylinders are respectively arranged on both sides of the second positioning block, and the output end of each third cylinder is provided with the shaping block. The side of the shaping block facing the rotor core is provided with an arc-shaped pressing surface that matches the outer arc surface of the rotor core.

[0014] Compared with the prior art, the rotor magnetizing assembly mechanism for preventing glue scratching provided by the present invention has a first extension section formed by the upper port of the through hole of the magnet bearing ring extending axially upward, serving as the inner blocking surface of the lower end of the magnet. The second extension section is formed by the outer wall of the adsorption fixture facing the fixture assembly extending axially downward, serving as the inner blocking surface of the upper end of the magnet. During the process of the assembly assembly attaching the magnet to the rotor core, the first extension section of the upper port of the through hole of the magnet bearing ring serves as the inner blocking surface of the lower end of the magnet, and the second extension section of the outer wall of the adsorption fixture serves as the inner blocking surface of the upper end of the magnet, continuously limiting and blocking the inner walls of both ends of the magnet. Simultaneously, the pressure rod maintains a pressing force on the magnet, ensuring that the magnet maintains a predetermined posture and cannot prematurely adhere to the rotor core as it descends and gradually approaches the rotor core with increasing magnetic force. The through holes in the center of the third moving plate and the magnet bearing ring are spaced apart to form an annular gap fit with the base column. This gap provides sufficient space for the adhesive on the outer wall of the rotor core, ensuring that the magnet will not shift its position due to premature adsorption during the entire process of descent and bonding, nor will it come into contact with or rub against the adhesive on the surface of the rotor core. This completely avoids the problems of adhesive being scratched, squeezed out, or contaminated, ensuring the uniformity of the adhesive layer and the bonding reliability between the magnet and the rotor core, and significantly improving the yield and product performance of the magnet bonding assembly.

[0024] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0025] like Figures 1 to 8 The diagram shows a schematic representation of the anti-adhesive-scratching rotor magnetizing assembly mechanism provided by the present invention. The anti-adhesive-scratching rotor magnetizing assembly mechanism includes an assembly component 10, a jig component 20, and a rounding heating component 30. It is conceivable that the anti-adhesive-scratching rotor magnetizing assembly mechanism also includes other functional components, such as mounting components, connecting components, etc., which are well-known to those skilled in the art and will not be described in detail here.

[0026] It should be noted that the anti-adhesive scratch rotor magnet assembly mechanism is used to complete the process of attaching magnets 200 to the rotor core 100. The magnets 200 are arc-shaped and have magnetism. The rotor core 100 and the magnets 200 should be existing technology and will not be described in detail here.

[0027] The assembly assembly 10 includes a first multi-axis moving device 11, a mounting plate 12 disposed on the first multi-axis moving device 11, a rotary motor 13 disposed on the mounting plate 12, a rotary connecting shaft 14 disposed on the output end of the rotary motor 13, an adsorption fixture 15 disposed on the rotary connecting shaft 14, a first cylinder 16 disposed on the mounting plate 12, a first moving plate 17 disposed on the output end of the first cylinder 16, and a pressure rod 18 disposed on the first moving plate 17.

[0028] The first multi-axis moving device 11 is used to drive the mounting plate 12 to move in multiple axes, thereby controlling its position. The output end of the rotary motor 13 is connected to the adsorption fixture 15 through the rotary connecting shaft 14, and is used to drive the adsorption fixture 15 to rotate in increments around its central axis.

[0029] The adsorption fixture 15 has a cylindrical structure, with multiple partition plates 151 spaced circumferentially along its outer outer wall. A receiving station is formed between two adjacent partition plates 151, and each receiving station contains an adsorption block 152. The partition plates 151 serve as physical isolation, preventing interference between magnets 200 in adjacent stations. They also act as lateral guide surfaces for the magnets 200, ensuring their correct posture within the receiving station. The magnets 200 can be adsorbed onto the adsorption block 152, which is used to adsorb and fix individual magnets 200. Before assembly, one magnet 200 is placed in each receiving station and fixed to the adsorption block 152. The loading of the adsorption fixture 15 is performed by an external assembly device, which is existing technology and will not be described further here.

[0030] Two first cylinders 16 are respectively located on both sides of the rotary motor 13. The output end of the first cylinder 16 is connected to the first moving plate 17, which is used to drive the first moving plate 17 to perform vertical lifting and lowering movements. A plurality of pressure rods 18 are fixed on the first moving plate 17. The number of pressure rods 18 is consistent with the number of accommodating positions on the adsorption fixture 15, and their positions correspond one-to-one.

[0031] Each pressure rod 18 is located above the gap between two adjacent partition plates 151, and the size of the pressure rod 18 is smaller than the distance between the two adjacent partition plates 151, thereby ensuring that the pressure rod 18 can be inserted into the receiving station without interfering with the partition plates 151. When the adsorption fixture 15 is fully loaded with the magnets 200 and needs to be unloaded, the first cylinder 16 drives the first moving plate 17 to press down vertically, and the first moving plate 17 drives multiple pressure rods 18 to move down synchronously. This causes the pressure rods 18 to extend into the gap between the partition plates 151, abut against the top of the magnets 200 and push them, so that multiple magnets 200 are simultaneously pushed out from the bottom of the adsorption fixture 15.

[0032] The fixture assembly 20 includes a frame 21, a base column 22 disposed on the frame 21, a first positioning block 23 disposed on the base column 22, a second cylinder 24 disposed on the frame 21, a second moving plate 25 disposed on the output end of the second cylinder 24, a connecting rod 26 disposed on the second moving plate 25, a third moving plate 27 disposed on the connecting rod 26, and a magnetic steel bearing ring 28 disposed on the third moving plate 27.

[0033] The base column 22 is vertically mounted on the frame 21, and the first positioning block 23 is fixed to its top. The first positioning block 23 is used to accurately position and support the rotor core 100 to be assembled, ensuring that the rotor core 100 remains vertical and fixed in position during assembly. Specifically, the outer diameter of the first positioning block 23 matches the inner diameter of the rotor core 100, so that the rotor core 100 can be fitted onto the first positioning block 23, and the bottom of the rotor core 100 is mounted on the base column 22. Three clearance grooves 231 are provided at intervals on the first positioning block 23. The clearance grooves 231 communicate with the outer side wall of the first positioning block 23, which are used to facilitate the circular heating assembly 30 to grasp the assembled rotor core 100. A detailed explanation will be given below in conjunction with the circular heating assembly 30. The second cylinder 24 is vertically mounted on the frame 21, and the output end is provided with the second moving plate 25, which is used to provide vertical lifting power.

[0034] Four connecting rods 26 are provided and located at the four corners of the second moving plate 25 and the third moving plate 27, respectively. One end of each connecting rod 26 is connected to the second moving plate 25, and the other end is connected to the third moving plate 27. The second moving plate 25 is connected to the third moving plate 27 through the four connecting rods 26, thereby forming a rigid transmission structure to ensure that the third moving plate 27 moves synchronously when the second moving plate 25 moves.

[0035] The magnet bearing ring 28 is fixedly mounted on the upper surface of the third movable plate 27. The magnet bearing ring 28 is used to receive multiple magnets 200 pushed out by the assembly assembly 10. Both the third movable plate 27 and the magnet bearing ring 28 have through holes 29 at their centers. The inner diameter of the through hole 29 is larger than the outer diameter of the base column 22, forming an annular clearance fit between them. This allows the third movable plate 27 and the magnet bearing ring 28 to be coaxially spaced outside the base column 22, ensuring that the vertical reciprocating movement of the third movable plate 27 and the magnet bearing ring 28 does not affect the base column 22 or the rotor core 100 mounted on the base column 22.

[0036] The upper port of the through hole 29 of the magnet bearing ring 28 extends axially upward to form a first extension section 291, which serves as an inner blocking surface at the lower end of the magnet 200. The outer wall of the adsorption fixture 15 facing the fixture assembly 20 extends axially downward to form a second extension section 151, which serves as an inner blocking surface at the upper end of the magnet 200.

[0037] Before the magnet 200 is pushed out by the pressure rod 18, the second cylinder 24 drives the magnet bearing ring 28 to rise to a high position, placing it at a certain distance above the rotor core 100. At this time, the pressure rod 18 pushes the magnet 200 out of the adsorption fixture 15. The lower end of the magnet 200 abuts against the magnet bearing ring 28, and the upper end is pressed by the pressure rod 18. The inner sidewalls of the upper and lower ends of the magnet 200 are respectively in close contact with the first extension section 291 and the second extension section 151. In this state, the magnet 200 is positioned entirely above the rotor core 100. Next, the magnet bearing ring 28 descends synchronously with the pressure rod 18 and the adsorption fixture 15. During the descent, the first extension section 291 and the second extension section 151 continuously limit and block the inner wall of the magnet 200, and the pressure rod 18 maintains the pressing force on the magnet 200. Therefore, even if the magnetic force gradually increases as it approaches the rotor core 100, the magnet 200 cannot adsorb and stick to it prematurely. At the same time, since the through hole 29 and the base column 22 are spaced apart, this gap can serve as a space for adhesive, so that the magnet will neither adsorb prematurely nor get smeared with adhesive during the descent. When the magnet 200 descends to the point where its two ends are flush with the two ends of the rotor core 100, the adsorption fixture 15 and the pressure rod 18 first retract upwards. At this time, the upper end of the magnet 200 loses the lateral constraint of the second extension section 151 and the pressure of the pressure rod 18. Under the action of magnetic force, the upper end of the magnet 200 tilts towards the core and is the first to adsorb and stick to it. Next, the magnet bearing ring 28 descends, causing the first extension section 291 to gradually move downwards and detach from the lower end of the magnet 200, releasing the obstruction to the lower end of the magnet 200. This allows the lower end of the magnet 200 to be attracted to the surface of the rotor core 100 under the action of magnetic force. It is conceivable that the adhesive on the outer wall of the rotor core 100 should be appropriately distributed in a discrete manner, rather than covering the entire surface. This could be in the form of a dotted array or multiple parallel adhesive lines, to avoid the adhesive being squeezed out of the rotor core 100 after the magnet 200 is attracted.

[0038] Since multiple magnets 200 may have uneven heights during assembly, the rounding heating assembly 30 is used to shape and heat-solidify the rotor core 100 equipped with the magnets 200. The rounding heating assembly 30 includes a second multi-axis moving device 31, a clamping device 32 disposed on the second multi-axis moving device 31, a second positioning block 33, two third cylinders 34 respectively located on both sides of the second positioning block 33, two shaping blocks 35 respectively disposed on the two third cylinders 34, a third multi-axis moving device 36, a pressure block 37 disposed on the third multi-axis moving device 36, and a heating device 38 disposed on the third multi-axis moving device 36.

[0039] The second multi-axis moving device 31 is used to drive the clamping device 32 to move in multiple axes, so as to control the clamping device 32 to transfer the rotor core 100 equipped with the magnet 200 on the jig assembly 20 to the second positioning block 33. The clamping device 32 is a three-jaw cylinder. The three output ends of the clamping device 32 can extend into the clearance groove 231 and open, thereby pressing against the inner wall of the rotor core 100 from the inside, realizing the inner clamping of the rotor core 100. This internal support method can avoid the external clamping from squeezing damage to the already attached magnet 200.

[0040] The structure of the second positioning block 33 is the same as that of the first positioning block 23. It is used to support the rotor core 100 on which the magnet 200 is assembled. The specific structure will not be described in detail here.

[0041] Two third cylinders 34 are symmetrically arranged on both sides of the second positioning block 33. Each third cylinder 34 has a shaping block 35 at its output end. The shaping block 35 has an arc-shaped pressing surface that matches the outer arc surface of the rotor core 100 on its side facing the rotor core 100. When the rotor core 100 is placed on the second positioning block 33, the two third cylinders 34 synchronously drive the shaping blocks 35 to converge towards the center, applying radial pressure to the rotor core 100 with the magnets 200 mounted on it from the outside. This eliminates gaps between the magnets 200 and ensures even spread of the adhesive. While the shaping blocks 35 apply radial pressure, the pressing block 37 presses against the upper surface of the rotor core 100 with the magnets 200 mounted on it via a third multi-axis moving device 36, applying axial pressure to ensure that the axial positions of the magnets 200 are consistent.

[0042] After the shaping block 35 and the pressing block 37 hold pressure for a certain period of time, the pressing block 37 is reset, and the third multi-axis moving device 36 moves the heating device 38 to the second positioning block 33 to heat the magnet 200 and the rotor core 100, so that the glue can be cured faster.

[0043] Compared with the prior art, the rotor magnet mounting mechanism for preventing glue scratching provided by the present invention has a first extension section 291 formed by the upper port of the through hole 29 of the magnet bearing ring 28 extending axially upward, serving as the inner blocking surface of the lower end of the magnet 200. The second extension section 151 is formed by the outer wall of the adsorption fixture 15 facing the fixture assembly 20 extending axially downward, serving as the inner blocking surface of the upper end of the magnet 200. During the process of the assembly assembly 10 attaching the magnet 200 to the rotor core 100, the first extension section 291 of the upper port of the through hole 29 of the magnet bearing ring 28 serves as the inner blocking surface of the lower end of the magnet 200, and the second extension section 151 of the outer wall of the adsorption fixture 15 serves as the inner blocking surface of the upper end of the magnet 200, thus continuously limiting and blocking the inner walls of both ends of the magnet 200. Simultaneously, the pressure rod 18 maintains a clamping force on the magnet 200, ensuring that the magnet 200 maintains its predetermined posture and cannot prematurely adhere to the rotor core 100 during its descent, as it gradually approaches the rotor core 100 and its magnetic force gradually increases. The through-hole 29 at the center of the third moving plate 27 and the magnet bearing ring 28, along with the base column 22, form an annular gap fit. This gap provides ample space for the adhesive on the outer wall of the rotor core 100, ensuring that the magnet 200 will not shift its position due to premature adhesion during the entire descent and bonding process, nor will it come into contact with or rub against the adhesive on the surface of the rotor core 100. This completely avoids the problems of adhesive being scratched, squeezed out, or contaminated, ensuring the uniformity and bonding reliability of the adhesive layer between the magnet 200 and the rotor core 100, significantly improving the yield and product performance of the magnet-attached assembly.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
