Description

Technical Field

[0001] This application belongs to the technical field of soldering mechanisms, and more specifically, relates to a soldering mechanism. Background Technology

[0002] In the electrical connection between the stator winding and the printed circuit board (PCB), traditional processes employ manual soldering. This not only suffers from slow soldering speed and low production capacity, but also leads to fluctuations in solder joint quality due to differences in operator skills, resulting in frequent defects such as incomplete soldering and cold solder joints. This labor-intensive production method not only extends the production cycle of individual products and keeps labor costs high, but also directly affects the stability and reliability of motor performance due to poor process consistency. With the continuous expansion of motor application scenarios and the acceleration of industrial upgrading, this inefficient and high-cost manufacturing model has become a prominent bottleneck restricting the large-scale and standardized production of motors, especially in high-end application fields such as new energy vehicle drive motors and industrial servo motors, where the limitations of traditional processes are becoming increasingly apparent.

[0006] It has a mounting groove for mounting a stator, the mounting groove extending vertically to support the axial arrangement of the stator in the vertical direction, and to support the end of the stator to be soldered protruding from the stator support base;

[0007] A soldering base having solder holes is used to press the wiring on the stator against the circuit board, and molten solder drips along the solder holes to the soldering position between the wiring and the circuit board.

[0009] As a further improvement to the above technical solution:

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] like Figure 1 and Figure 2 As shown, this application provides a soldering mechanism for automated welding of motor stators, including a stator support 2, a soldering base 3, and a soldering base drive assembly 4.

[0033] The stator support 2 is provided with a mounting groove extending in the vertical direction. The mounting groove is used to fix the stator 1 and keep its axial direction vertical, while ensuring that the end of the stator 1 to be soldered protrudes from the upper surface of the support 2.

[0034] The solder holder 3 is provided with solder holes 31. The solder holder 3 can stably press the terminals of the stator 1 to the predetermined soldering position on the circuit board. The solder holes 31 serve as a flow channel to allow molten solder to accurately drip onto the contact area between the terminals and the circuit board.

[0035] The solder holder drive assembly 4 adopts a linear drive mechanism, which can control the movement of the solder holder 3 and realize the controllable approach or separation of the solder holder 3 and the end of the stator 1 to be soldered.

[0036] The soldering mechanism provided in this application replaces manual operation with mechanical positioning, solving technical problems such as inaccurate positioning and difficulty in controlling the amount of solder in traditional soldering processes. It is suitable for automated soldering operations of motor stators and circuit boards.

[0037] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the solder base 3 is provided with a positioning groove 32 that mates with the stator support 2. The size and shape of the positioning groove 32 match the outer contour of the stator support 2. When the solder base 3 moves towards the stator 1 under the drive of the solder base drive assembly 4, the solder base 3 forms a mechanical engagement with the stator support 2 through the positioning groove 32, ensuring the relative positional accuracy between the solder base 3 and the stator 1. During this process, the front end of the stator support 2 is embedded inside the positioning groove 32, forming a stable positioning reference. At the same time, the solder base 3 accurately presses the terminals of the stator 1 onto the predetermined soldering position on the circuit board. This mechanical positioning structure effectively eliminates the positioning deviation caused by manual operation in the traditional soldering process, ensuring the precise alignment of the solder hole 31 with the soldering position, thereby improving the soldering quality and process consistency.

[0038] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the solder holder drive assembly 4 includes a fixed base 41, a drive component, and a movable base 42. The fixed base 41 serves as the mounting base for the entire drive assembly and is rigidly fixed to the equipment frame. The movable base 42 cooperates with the fixed base 41 through a linear guide mechanism to ensure the linearity and stability of its movement trajectory. The drive component adopts a linear drive device such as an electric push rod or a cylinder, with one end fixedly connected to the fixed base 41 and the other end connected to the movable base 42. The solder holder 3 is mounted on the movable base 42 by fasteners and moves synchronously with the movable base 42. When the drive component is working, it can control the movable base 42 to drive the solder holder 3 to move in the vertical direction, realizing a controllable approach or separation action between the solder holder 3 and the end of the stator 1 to be soldered.

[0039] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the solder socket drive assembly 4 is provided with a travel limiting mechanism. This mechanism includes an upper limit member 43 fixedly mounted on the fixed base 41 and a first limiting protrusion 421 disposed on the movable base 42. When the drive member drives the movable base 42 to move upward to the return end position, the upper limit member 43 gradually approaches the first limiting protrusion 421 until the two form mechanical contact. This rigid limiting structure can accurately control the maximum return position of the movable base 42 and prevent the drive assembly from overtraveling.

[0040] like Figure 1 and Figure 2As shown in a specific embodiment of this application, the solder holder drive assembly 4 is provided with a lower limit positioning mechanism, which consists of a lower limit member 44 mounted on the movable seat 42 and a corresponding second limit protrusion 411 on the fixed seat 41. During the downward movement, when the drive member pushes the movable seat 42 towards the stator 1, the lower limit member 44 moves downward synchronously with the movable seat 42 and gradually approaches the second limit protrusion 411. When the solder holder 3 reaches the preset working position, the lower limit member 44 forms rigid contact with the second limit protrusion 411, thereby precisely limiting the downward stroke endpoint position of the movable seat 42. This lower limit positioning mechanism, together with the aforementioned upper limit positioning mechanism, constitutes a complete stroke control system, ensuring reliable control of the vertical movement range of the solder holder 3.

[0041] like Figure 1 and Figure 2 As shown, in one specific embodiment of this application, the soldering mechanism is provided with a first mounting base 5 as the mounting foundation of the overall device. The first mounting base 5 is fixed to the external equipment frame or work platform by fasteners. The fixing seat 41 is rigidly installed on the first mounting base 5 by bolt connection or locating pin engagement, forming a stable support structure.

[0042] like Figure 1 and Figure 2 As shown in one specific embodiment of this application, the solder hole 31 provided on the solder base 3 adopts a tapered structure design, and the cross-sectional dimension of the tapered hole decreases continuously from top to bottom along the axial direction. This tapered hole structure can effectively guide the molten solder to flow along a predetermined path, forming a natural convergence effect during the solder droplet process. The inner surface of the tapered hole 31 is polished to reduce the solder flow resistance, and its minimum hole diameter matches the size of the terminal to be soldered, ensuring that the solder accurately covers the soldering area.

[0043] like Figure 1 and Figure 3 As shown, in a specific embodiment of this application, the soldering mechanism includes a second mounting base 6 and a rotary drive 7. The second mounting base 6 is mounted on an external equipment rack or work platform, providing a stable mounting foundation for the rotary drive 7. The rotary drive 7 is driven by a servo motor or stepper motor, and its fixed end is mounted on the second mounting base 6. The stator support 2 is mounted on the movable end of the rotary drive 7 and can rotate synchronously with the output shaft of the rotary drive 7. This rotary drive mechanism can control the circumferential position of the stator 1, so that multiple terminals on the stator 1 are sequentially aligned with the solder holes 31 of the soldering base 3, realizing the automatic positioning function of multiple solder points. The rotation angle and speed of the rotary drive 7 are programmable and controllable to meet the soldering process requirements of stators of different specifications.

[0044] like Figure 1 and Figure 3As shown, in one specific embodiment of this application, the soldering mechanism is provided with a sliding component 8 as a moving platform for the second mounting base 6. The second mounting base 6 is rigidly connected to the sliding component of the sliding component 8. The sliding component 8 adopts a transmission combination of linear guide rail and ball screw, which can drive the second mounting base 6 to move along a linear trajectory in the horizontal direction or at a preset angle. The drive source of the sliding component 8 is a servo motor or a stepper motor, which is connected to the ball screw through a reduction mechanism to realize the position control of the second mounting base 6. This sliding mechanism enables the stator support 2 to have planar movement capability, and the working position can be adjusted according to the welding position requirements of stators 1 of different specifications, thus expanding the process adaptability of the soldering mechanism.

[0045] In one specific embodiment of this application, the soldering mechanism is further equipped with an inspection camera (not shown) as a soldering quality monitoring device. The inspection camera is mounted near the soldering station via an adjustable bracket, with its optical axis maintaining a preset angle with the soldering portion of the stator 1, ensuring that the soldering position is completely covered within the inspection camera's field of view. The inspection camera uses an industrial-grade CCD or CMOS sensor, coupled with a telecentric lens of appropriate magnification, to clearly capture the solder joint formation state. Image acquisition by the inspection camera is synchronized with the soldering process, and the image processing system analyzes solder quality parameters in real time, including solder quantity, solder joint shape, and coverage area. This visual inspection system provides a reliable closed-loop quality control method for the soldering process, ensuring that each solder joint meets the preset quality standards.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
