[0002] In today's rapidly evolving technological landscape, micromotors serve as the core power source for numerous precision devices, finding widespread application in electronics, medical, automotive, and aerospace fields. From vibration feedback modules in smartphones to precision drive components in high-end medical devices, micromotors, with their compact size and efficient power output, endow various products with exceptional functionality and reliability. The casing of a micromotor, as a crucial barrier protecting internal precision components from external environmental interference and ensuring stable motor operation, directly impacts the overall performance of the motor through the quality of its welded joints.
[0003] However, traditional welding processes often suffer from slow welding speed, low precision, and unstable quality when dealing with the delicate and complex seams of micro motor housings, making it difficult to meet the growing demand for large-scale, high-quality production. Against this backdrop, a high-speed welding device for micro motor welding has been proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a high-speed welding device for welding micro motors, so as to solve the problems of slow welding speed, low precision and unstable quality that occur when the traditional welding process mentioned in the background art is faced with the fine and complex seams of micro motor shells.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-speed welding device for welding micro motors includes: a mounting plate, on the upper surface of which two sets of connecting columns are fixedly mounted, a motor is fixedly mounted on the upper surface of one set of connecting columns, the output shaft of the motor and the upper surface of the other set of connecting columns are respectively fixedly and rotatably mounted with transmission discs, transmission belts are fitted on the outer surfaces of the two sets of transmission discs, and an electromagnetic welding mechanism is fixedly mounted on the upper surface of the other end of the mounting plate, the space between the electromagnetic welding mechanism and the transmission belt being able to accommodate the housing of a micro motor.
[0007] Preferably, the electromagnetic welding mechanism includes a connecting frame, which is fixedly mounted on the upper surface of the mounting plate and flush with the outer surface of the transmission belt. A placement plate is fixedly mounted on the outer surface of the connecting frame, and the other end of the placement plate is simultaneously engaged with the outer surface of the transmission belt.
[0008] Preferably, the housing of a micro motor can be filled between the connecting frame and the transmission belt, and the housing of the micro motor can be rotated and conveyed on the surface of the placement plate under the top contact drive of the transmission belt.
[0009] Preferably, the seams of the housing of the micro motor conveyed by the transmission belt can be electromagnetically welded by electromagnetic induction wires. The electromagnetic induction wires are installed inside a heat insulation cylinder, which is fixedly installed on the upper surface of the power module. The power module is fixedly installed on the upper surface of the support plate, which is fixedly installed between the outer surfaces of the two sets of connecting columns. The electromagnetic induction wires are electrically connected to the power module.
[0010] Preferably, a heat insulation plate is fixedly installed on the upper surface of the connecting frame.
[0011] Preferably, the heat insulation plate is L-shaped, so that the bent part of the heat insulation plate covers the upper end of the heat insulation cylinder.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. Through the design of the transmission disc, motor, transmission belt, and electromagnetic welding mechanism, when welding the joints of the motor housing, the motor and electromagnetic welding mechanism are started. The started motor drives the transmission disc to rotate, which in turn drives the transmission belt fitted on the outer surface. Then, the worker can fill the space between the transmission belt and the electromagnetic welding mechanism, so that the transmission belt contacts the outer surface of the motor housing, and the other end of the motor housing contacts the end of the electromagnetic welding mechanism. The motor housing, being rotated and transported by the transmission belt, is then electromagnetically heated 360° by the electromagnetic welding mechanism. Under the action of the alternating magnetic field, the motor... An induced current is generated inside the casing. This induced current generates Joule heat on the joint surface of the motor casing, causing the metal at the joint to heat up rapidly to a molten state. At the same time, the electromagnetic force creates a tight pressure between the joints, causing the molten metal to fuse together under pressure. After cooling, a strong welded joint is formed. This welding process only requires a worker to fill the motor casing between the transmission belt and the electromagnetic welding mechanism, making the entire welding process highly automated and reducing manual intervention. Compared with traditional welding methods that require frequent manual adjustment of welding positions and control of welding parameters, this method only requires one person to fill the motor casing, which greatly saves labor costs and improves production efficiency.
[0014] 2. Through the design of the power module, electromagnetic induction wire, connecting frame, and placement plate, when welding the joint of the motor housing, the joint of the motor housing can be inserted between the transmission belt and the connecting frame with the joint facing upwards. This allows the transmission belt to contact the outer surface of the motor housing for transmission, while the other end of the motor housing, contacting the connecting frame, is rotated and transported across the surface of the placement plate by the transmission belt. Since the joint of the motor housing is higher than the transmission belt, it is flush with the electromagnetic induction wire. The electromagnetic induction wire can then be powered by the power module to generate a high-frequency alternating current, which in turn generates a strong alternating magnetic field. Under the influence of this alternating magnetic field, the motor housing... An induced current is generated inside the motor housing. This induced current generates Joule heating on the seam surface of the motor housing, causing the metal at the seam contact surface to rapidly heat up to a molten state. At the same time, the electromagnetic force creates tight pressure between the seams, causing the molten metal to fuse together under pressure. After cooling, a strong welded joint is formed. This welding process only requires the operator to fill the motor housing between the transmission belt and the connecting frame. Through the continuous transmission of the transmission belt, the motor housing can be continuously transported and welded, avoiding the frequent clamping and positioning time in traditional welding methods. This greatly shortens the welding cycle of a single product, improves production efficiency, and is suitable for large-scale mass production. Attached Figure Description

[0019] 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.
[0020] As shown in Figures 1 and 2, this embodiment provides a high-speed welding device for welding micro motors, including: a mounting plate 1, two sets of connecting columns 101 are fixedly mounted on the upper surface of the mounting plate 1, a motor 103 is fixedly mounted on the upper surface of one set of connecting columns 101, the output shaft of the motor 103 and the upper surface of the other set of connecting columns 101 are respectively fixedly and rotatably mounted with transmission disks 102, transmission belts 104 are fitted on the outer surfaces of the two sets of transmission disks 102, and an electromagnetic welding mechanism 2 is fixedly mounted on the upper surface of the other end of the mounting plate 1, the space between the electromagnetic welding mechanism 2 and the transmission belt 104 can be filled with the housing of the micro motor.
[0021] Through the design of the transmission disc 102, motor 103, transmission belt 104, and electromagnetic welding mechanism 2, when welding the joint of the motor housing, the motor 103 and electromagnetic welding mechanism 2 can be started. The started motor 103 drives the transmission disc 102 to rotate, which in turn drives the transmission belt 104 fitted on the outer surface. Then, the worker can fill the space between the transmission belt 104 and the electromagnetic welding mechanism 2, so that the transmission belt 104 touches the outer surface of the motor housing, and the other end of the motor housing touches the end of the electromagnetic welding mechanism 2. The motor housing is then rotated and transported away by the transmission belt 104. The rotating motor housing is then electromagnetically heated 360° by the electromagnetic welding mechanism 2. The alternating magnetic field induces a current inside the motor housing, which generates Joule heating on the joint surface of the motor housing, rapidly heating the metal at the joint to a molten state. Simultaneously, the electromagnetic force creates tight pressure between the joints, causing the molten metal to fuse together under pressure and form a strong welded joint after cooling. This welding process only requires a worker to fill the motor housing between the transmission belt 104 and the electromagnetic welding mechanism 2, making the entire welding process highly automated and reducing manual intervention. Compared to traditional welding methods that require frequent manual adjustments to the welding position and control of welding parameters, this method only requires one person to fill the motor housing, greatly saving labor costs and improving production efficiency.
[0022] As shown in Figure 3, the electromagnetic welding mechanism 2 includes a connecting frame 204, which is fixedly installed on the upper surface of the mounting plate 1 and flush with the outer surface of the transmission belt 104. A placement plate 206 is fixedly installed on the outer surface of the connecting frame 204, and the other end of the placement plate 206 is simultaneously engaged with the outer surface of the transmission belt 104. A micro motor housing can be filled between the connecting frame 204 and the transmission belt 104, and the micro motor housing can be rotated and conveyed on the surface of the placement plate 206 under the top contact transmission of the transmission belt 104. The seam of the micro motor housing conveyed by the transmission belt 104 can be electromagnetically welded by an electromagnetic induction wire 203. The electromagnetic induction wire 203 is inserted into a heat insulation cylinder 202, which is fixedly installed on the upper surface of the power module 201. The power module 201 is fixedly installed on the upper surface of the support plate 105, which is fixedly installed between the outer surfaces of two sets of connecting columns 101. The electromagnetic induction wire 203 is electrically connected to the power module 201. To prevent staff from getting burned, a heat insulation plate 205 is fixedly installed on the upper surface of the connecting frame 204. The heat insulation plate 205 is L-shaped, so that the bent part of the heat insulation plate 205 covers the upper end of the heat insulation cylinder 202.
[0023] Through the design of the power module 201, electromagnetic induction wire 203, connecting frame 204, and placement plate 206, when welding the joint of the motor housing, the joint of the motor housing can be filled between the transmission belt 104 and the connecting frame 204 with the joint facing upwards. This allows the transmission belt 104 to contact the outer surface of the motor housing for transmission, and the other end of the motor housing, which is in contact with the connecting frame 204, is rotated by the transmission belt 104 and transported away on the surface of the placement plate 206. The joint of the motor housing is higher than the transmission belt 104, allowing the joint to be flush with the electromagnetic induction wire 203. The electromagnetic induction wire 203 can then be powered by the power module 201 to generate a high-frequency alternating current, which in turn generates a strong alternating magnetic field. Under the influence of an alternating magnetic field, an induced current is generated inside the motor housing. This induced current generates Joule heating on the joint surface of the motor housing, causing the metal at the joint contact surface to rapidly heat up to a molten state. At the same time, the electromagnetic force creates a tight pressure between the joints, causing the molten metal to fuse together under pressure. After cooling, a strong welded joint is formed. This welding process only requires the operator to fill the motor housing between the transmission belt 104 and the connecting frame 204. Through the continuous transmission of the transmission belt 104, the motor housing can be continuously transported and welded, avoiding the frequent clamping and positioning time in traditional welding methods. This greatly shortens the welding cycle of a single product, improves production efficiency, and is suitable for large-scale mass production.
[0024] Based on the above technical solution, the working steps of this solution are summarized as follows: When welding the joint of the motor housing, the motor 103 and power module 201 can be started. The started motor 103 can drive the transmission disc 102 to rotate, which in turn drives the transmission belt 104 fitted on the outer surface. Then, the worker can fill the motor housing with the joint facing upwards between the transmission belt 104 and the connecting frame 204, so that the transmission belt 104 can contact the outer surface of the motor housing for transmission. The other end of the motor housing, which is in contact with the connecting frame 204, is rotated by the transmission belt 104 and transported away on the surface of the placement plate 206. The joint of the motor housing is higher than the transmission belt 104. This allows the seam to be flush with the electromagnetic induction line 203, which can be powered by the activated power module 201 to generate a high-frequency alternating current, thereby generating a strong alternating magnetic field. Under the action of the alternating magnetic field, an induced current is generated inside the motor housing. This induced current generates Joule heating on the seam surface of the motor housing, and the motor housing, which is being driven and rotated, can be electromagnetically heated 360° by the electromagnetic induction line 203, causing the metal at the seam contact surface to heat up rapidly to a melting state. At the same time, the electromagnetic force will generate tight pressure between the seams, causing the molten metal to fuse together under the pressure. After cooling, a strong welded joint is formed, and the motor housing with the welded seam can be transported away by the transmission belt 104.
[0025] In summary, this method automates the welding process by requiring only one worker to fill the motor housing between the transmission belt 104 and the connecting frame 204. This significantly reduces manual intervention compared to traditional welding methods that require frequent manual adjustments to the welding position and control of welding parameters. This method only requires one person to fill the motor housing, greatly saving labor costs and improving production efficiency.
