Description

A micro motor automatic welding device Technical Field

[0001] This utility model relates to the field of motor welding equipment technology, and specifically discloses a micro motor automatic welding device. Background Technology

[0002] A micro motor is a small electric motor with an output power typically below several hundred watts. Micro motors are usually less than 160 millimeters in size and are characterized by their small size, light weight, high efficiency, and ease of control. During the production of micro motors, welding equipment is required to weld the motors to ensure a firm connection between the corresponding components.

[0003] Chinese Patent CN213469898U discloses an automatic micro-motor welding device, including a base with a transmission belt movably connected to the top of the base. Compared with existing ordinary micro-motor welding devices, this invention, through structures such as a second hydraulic rod and a buffer box, can clamp micro-motors of different specifications and types. The height of the solder guide can be adjusted by a slider, thereby welding micro-motors of different specifications and improving the device's versatility. Simultaneously, the buffer box and fixing ring can stably fix the micro-motor, preventing it from shifting during welding and affecting the welding effect. Furthermore, the position of the solder head can be adjusted by sliding the first hydraulic rod left and right. With the two solder guides, multiple solder points can be welded, facilitating operation. However, the aforementioned device is not convenient for limiting the motor on the conveyor belt, which can easily cause the motor to tip over during conveyor belt operation, increasing the user's workload in righting the motor and affecting welding efficiency to some extent. Therefore, to solve the above problems, this invention proposes an automatic micro-motor welding device. Summary of the Invention

[0004] The present invention aims to provide an automatic welding device for micro motors, which can limit the micro motors on the conveyor belt, prevent the micro motors from tipping over during movement, reduce the workload of users in straightening the motors, and improve the efficiency of micro motor welding operations.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic welding device for micro motors includes a base and a welding mechanism. The welding mechanism is located above the base and includes a solder head. A first telescopic rod is connected above the solder head. Solder boxes are located on both sides of the first telescopic rod. Solder strip guides are connected to the sides of the two solder boxes that are close to each other. A conveyor belt is located below the solder head. Multiple limiting mechanisms arranged in a linear array are arranged on the surface of the conveyor belt. Each limiting mechanism includes a mounting plate. A base plate is connected above the mounting plate. Two clamping plates are symmetrically arranged above the base plate. Multiple springs arranged in a linear array are connected to the sides of the two clamping plates that are far from each other. Limiting rods are located inside the springs. A side plate is connected to the end of the springs that is far from the clamping plates.

[0007] As a further feature of the above solution, a sliding plate is connected to the outer side of the first telescopic rod. Both ends of the sliding plate are provided with sliding rods and are slidably connected to the sliding rods. This allows the sliding plate and the first telescopic rod to be stably supported while ignoring the movement direction of the first telescopic rod. A third telescopic rod is connected to one side of the sliding plate, which can provide power for the movement of the first telescopic rod and the sliding plate. A bracket is connected to the bottom of the third telescopic rod, which can provide stable support for the third telescopic rod and the sliding rod.

[0008] As a further feature of the above solution, the top of the bracket is provided with a through hole, through which the first telescopic rod passes. This avoids positional conflict between the bracket and the first telescopic rod, reducing the overall height of the welding mechanism. A second telescopic rod is connected to the bottom of the solder box for easy adjustment of its position. A support base is connected to the outside of the second telescopic rod. The support base is detachably connected to the bracket, providing stable support for the second telescopic rod and facilitating the installation and maintenance of the second telescopic rod and the support base.

[0009] As a further provision of the above scheme, a support shaft and a power shaft are respectively provided at both ends of the conveyor belt. Both ends of the support shaft and the power shaft are connected to support plates, which can provide stable support for components such as the conveyor belt and the limiting mechanism. One end of the power shaft is connected to a drive motor, which can drive the conveyor belt and the limiting mechanism above it to move through the operation of the drive motor. A base is connected to the outside of the drive motor, and the base is connected to the support plate, which can provide stable support for the drive motor.

[0010] As a further feature of the above solution, a battery compartment and a storage box are respectively provided on the upper two sides of the base to facilitate the placement of related accessories and tools in the device for user access. A storage battery is provided inside the battery compartment to improve the device's battery life, ensuring that the same micro motor can be welded completely and avoiding secondary welding after power failure from affecting the quality of micro motor welding.

[0011] As a further feature of the above solution, the lower end of the mounting plate is detachably connected to the conveyor belt surface, facilitating the assembly and disassembly of the mounting plate and the entire limiting mechanism. The mounting plate is detachably connected to the base plate, and the lower end of the side plate is connected to the base plate, facilitating the assembly, disassembly, and maintenance of the aforementioned components. The limiting rod passes through the interior of the side plate and is slidably connected to the side plate, providing support for the clamping plate while limiting its direction of movement.

[0012] As a further feature of the above solution, a controller is provided on one side of the base to facilitate the control of the operation of relevant components in the device.

[0013] The notches at both ends of the conveyor belt in Figure 1 of the specification of this utility model are only for the convenience of those skilled in the art to understand the installation position of the power shaft and the support shaft, and are not intended to limit this application. The conveyor belt does not have the above-mentioned notches in actual use.

[0014] The present invention has the following beneficial effects during use:

[0015] The combination of the sliding plate, sliding rod, and third telescopic rod in the welding mechanism allows the sliding plate and the first telescopic rod to slide along the direction of the sliding rod by extending and retracting the third telescopic rod. This adjusts the position of the first telescopic rod and the solder head below it, thereby changing the welding point. The use of the second telescopic rod allows the user to quickly adjust the position of the solder box and solder bar guide by controlling the extension and retraction of the second telescopic rod, making it suitable for welding operations of different models of micro motors.

[0016] The combination of two clamping plates, elastic pads, and multiple springs in the limiting mechanism can clamp different models of micro motors to limit their position and prevent them from tipping over during the movement of the conveyor belt. The sliding connection between the limiting rod and the side plate can provide support for the clamping plates while limiting their direction of movement, preventing the clamping plates from swaying up and down with the springs.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to Figures 1-4 and the embodiments.

[0025] An embodiment discloses an automatic welding device for micro motors, including a base 1 and a welding mechanism 2. The welding mechanism 2 is arranged above the base 1. The welding mechanism 2 includes a solder head 22. A first telescopic rod 21 is connected above the solder head 22. Solder boxes 24 are arranged on both sides of the first telescopic rod 21. Solder strip guides 23 are connected to the side of the two solder boxes 24 that are close to each other. A conveyor belt 3 is arranged below the solder head 22. Multiple limiting mechanisms 4 arranged in a linear array are arranged on the surface of the conveyor belt 3. Each limiting mechanism 4 includes a mounting plate 41. A base plate 42 is connected above the mounting plate 41. Two clamping plates 44 are symmetrically arranged above the base plate 42. Multiple springs 46 arranged in a linear array are connected to the side of the two clamping plates 44 that are far from each other. A limiting rod 45 is arranged inside the spring 46. A side plate 43 is connected to the end of the spring 46 that is away from the clamping plate 44.

[0026] As shown in Figures 1 and 2, a sliding plate 27 is connected to the outer side of the first telescopic rod 21. Both ends of the sliding plate 27 are provided with sliding rods 271 and are slidably connected to the sliding rods 271. This allows the sliding plate 27 and the first telescopic rod 21 to be unaffected by the direction of movement of the first telescopic rod 21. A third telescopic rod 28 is connected to one side of the sliding plate 27, which provides power for the movement of the first telescopic rod 21 and the sliding plate 27. A bracket 29 is connected to the lower part of the third telescopic rod 28, which provides stable support for the third telescopic rod 28 and the sliding rods 271.

[0027] As shown in Figures 1 and 2, the top of the bracket 29 is provided with a through hole 291, and the first telescopic rod 21 passes through the inside of the through hole 291, which can avoid the position of the bracket 29 and the first telescopic rod 21 from conflicting and reduce the overall height of the welding mechanism 2. The bottom of the solder box 24 is connected to a second telescopic rod 25, which facilitates the adjustment of the position of the solder box 24. The outside of the second telescopic rod 25 is connected to a support base 26. The support base 26 is detachably connected to the bracket 29, which can provide stable support for the second telescopic rod 25 and facilitate the installation and maintenance of the second telescopic rod 25 and the support base 26.

[0028] As shown in Figure 1, the conveyor belt 3 is provided with a support shaft 32 and a power shaft 31 at both ends. Both ends of the support shaft 32 and the power shaft 31 are connected to support plates 33, which can provide stable support for the conveyor belt 3 and the limiting mechanism 4. One end of the power shaft 31 is connected to a drive motor 34, which can drive the conveyor belt 3 and the limiting mechanism 4 above it to move through the operation of the drive motor 34. The outer side of the drive motor 34 is connected to a base 35, which is connected to the support plate 33 and can provide stable support for the drive motor 34.

[0029] As shown in Figure 1, a battery compartment 11 and a storage box 13 are respectively provided on the upper two sides of the base 1, which facilitates the placement of related accessories and tools in the device for user access. A battery 12 is provided inside the battery compartment 11, which can improve the device's endurance and ensure that the same micro motor can be welded to completion, avoiding secondary welding after power failure from affecting the quality of micro motor welding.

[0030] As shown in Figures 1, 3, and 4, the lower end of the mounting plate 41 is detachably connected to the surface of the conveyor belt 3, facilitating the assembly and disassembly of the mounting plate 41 and the entire limiting mechanism 4. The mounting plate 41 is detachably connected to the base plate 42, and the lower end of the side plate 43 is connected to the base plate 42, facilitating the assembly, disassembly, and maintenance of the aforementioned components. The limiting rod 45 passes through the interior of the side plate 43 and is slidably connected to the side plate 43, providing support for the clamping plate 44 while restricting the direction of movement of the clamping plate 44.

[0031] As shown in Figure 1, a controller 5 is provided on one side of the base 1 to facilitate the control of the operation of the relevant components in the device.

[0032] The automatic welding device for micro motors disclosed in this embodiment involves connecting the battery 12 to an external power source and fully charging it before use. The end of the conveyor belt 3 where the drive motor 34 is installed is considered the downstream end of the conveyor belt 3, and the end furthest from the drive motor 34 is considered the upstream end. The micro motor to be welded is placed inside the two clamping plates 44 in the upstream limiting mechanism 4, causing the micro motor to press against the elastic pad 441 and spring 46. This causes the limiting rod 45 to slide inside the side plate 43. Under the rebound of the spring 46, the clamping plates 44 and elastic pad 441 clamp the micro motor. The controller 5 is used to start the drive motor 34, which drives the conveyor belt 3 via the power shaft 31. The conveyor belt 3 drives the upstream limiting mechanism 4 and the micro motor downstream. When the micro motor reaches the lower end of the welding mechanism 2, the drive motor 34 is turned off. The controller 5 is then used to sequentially control the extension and retraction of the two second telescopic rods 25. The positions of the tin box 24 and the solder bar guide 23 are determined by the controller 5, which controls the extension and retraction of the third telescopic rod 28. This causes the slide plate 27 and the first telescopic rod 21 to slide along the direction of the slide bar 271. After aligning the positions of the first telescopic rod 21 and the solder head 22 below it with the target welding point, the third telescopic rod 28 is closed, stopping its extension and retraction. The controller 5 is then activated to start the first telescopic rod 21, causing the solder head 22 to move downwards. The target welding point can then be welded using the solder head 22. After welding is completed, the controller 5 is activated to start the drive motor 34, moving the downstream limiting mechanism 4 and the micro motor below the welding mechanism 2. Welding can then continue. When the welded micro motor moves to a position close to the drive motor 34, the micro motor is removed from the inside of the two grippers in the limiting mechanism 4. This allows the downstream limiting mechanism 4 to rotate upstream along with the conveyor belt 3, so that the position of the micro motor can be further restricted.

[0033] When the external power supply fails, the first telescopic rod 21, solder head 22, second telescopic rod 25 and third telescopic rod 28 are immediately connected to the battery 12 to ensure that the above components can complete the welding of the micro motor located below the welding mechanism 2, and avoid secondary welding from affecting the welding quality of the micro motor.

[0034] The components disclosed in this utility model, including the base 1, conveyor belt 3, controller 5, battery compartment 11, battery 12, storage box 13, first telescopic rod 21, solder head 22, solder bar guide 23, solder box 24, second telescopic rod 25, support seat 26, slide rod 271, third telescopic rod 28, bracket 29, power shaft 31, support shaft 32, support plate 33, drive motor 34, mounting plate 41, side plate 43, clamping plate 44, elastic pad 441, limit rod 45, and spring 46, are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
