Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to a micro switch welding system based on visual recognition. Background Art

[0002] In the field of electronic equipment manufacturing, micro switches, as core components for switching circuits, are widely used in industries such as smart homes, automotive electronics, and consumer electronics. With the rapid development of the Internet of Things and smart manufacturing, market demand for various terminal devices has exploded, driving the continued expansion of the micro switch market. According to industry statistics, global annual demand for micro switches has exceeded 10 billion units and continues to maintain an average annual growth rate of over 10%. The need for large-scale, efficient, and high-quality production is becoming increasingly urgent.

[0003] Currently, the soldering process for micro switches still relies primarily on manual labor in industrial practice. This traditional model is a unique yet challenging feature of the production line. Workers must hold the soldering iron for extended periods, carefully visually identifying the soldering position between the pins and the circuit board under strong light, and then complete the soldering with delicate manual movements. This process severely restricts production efficiency, as individual workers are limited by their physiological limitations, resulting in a limited number of soldering operations per hour. In the context of modern production lines striving for high-speed, efficient operation, manual soldering significantly slows down the overall process, making it difficult to meet the demands of large-scale production.

[0004] Manual soldering is even more fraught with quality issues. Welding quality is closely linked to the operator's technical proficiency. New workers, due to their lack of experience, often fail to accurately control soldering temperature and timing, resulting in a defective soldering rate as high as 15%-20%. Experienced workers, on the other hand, can easily become fatigued and experience reduced hand stability after long, intense work periods. Or, they may be distracted by daily life, losing their focus. This can lead to cold solder joints, resulting in poor contact and frequent signal interruptions and malfunctions. Solder leaks can directly cause circuit breakage, rendering the product completely useless. Furthermore, improper solder quantity control is a common problem. Excessive solder can cause short circuits and damage the circuit board, while too little can lead to insufficient mechanical strength, making the solder joints susceptible to detachment during subsequent transportation and use.

[0005] Manual welding also carries with it a host of hidden costs. With socioeconomic development, labor costs have climbed annually, leading to a continuous increase in companies' investment in manual welding. Furthermore, due to the numerous uncontrollable factors associated with manual welding, product quality is unstable, with significant fluctuations in quality between batches, making it difficult to establish consistent quality standards.

[0036] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0038] Example 1

[0039] like Figure 1 、 Figure 4As shown, in order to improve the efficiency of welding and installation of the micro switch and improve the welding quality, the present embodiment provides a system for welding the micro switch. The system includes a frame group, a connecting mechanism 7, a supporting mechanism 6, a wire feeding mechanism 3, a welding component 4, an industrial camera 5, an electrical control box 13, etc. The supporting mechanism 6 is connected and installed on the frame group through the connecting mechanism 7. Under the control of the frame group, the supporting mechanism 6 can move arbitrarily on the horizontal plane, providing support for welding the micro switch passing below the supporting mechanism 6. The wire feeding mechanism 3 is installed on the connecting mechanism 7, and the welding component 4 is installed below the supporting mechanism 6. The bottom of the solder wire wound on the wire feeding mechanism 3 is adjacent to the bottom of the welding component 4. Thus, the welding process of the micro switch is completed through the cooperation of the welding component 4 and the wire feeding mechanism 3. In order to adjust the positions of the welding component 4 and the wire feeding mechanism 3 according to the position of the micro switch, the industrial camera 5 is installed on the side of the welding component 4. The frame group, the supporting mechanism 6, the wire feeding mechanism 3, the welding component 4, and the industrial camera 5 are all connected to the electrical control box 13. Therefore, the electrical control box 13 can receive the intake information of the industrial camera 5, and then control the frame group and the supporting mechanism 6 to work to adjust the positions of the wire feeding mechanism 3 and the welding component 4, and complete the welding process of the micro switch under the work of the wire feeding mechanism 3 and the welding component 4.

[0040] As Figure 1 , Figure 2 , Figure 3 As shown, in order to realize the adjustment of the position of the welding component 4, the frame group includes a first frame 1 and a second frame 2. The first frame 1 is set as a U-shaped structure, and the opening of the first frame 1 faces downward. A first threaded rod 12 is installed on the top of the first frame 1. The first threaded rod 12 is arranged along the length direction of the first frame 1, and the end of the first threaded rod 12 is connected to the power output shaft of the first motor 11. The second frame 2 includes a guide rail 22. The guide rail 22 is vertically arranged on the top of the first frame 1, and an end frame 24 is fixedly arranged at the end of the guide rail 22. A splicing plate 26 is arranged in parallel on the side of the end frame 24. Two first pulleys 23 are arranged vertically between the end frame 24 and the splicing plate 26. A central shaft 25 passes through the middle of the first pulley 23. The end of the central shaft 25 is inserted into the end frame 24 and the splicing plate 26 through a bolt connection. The two first pulleys 23 are respectively arranged on the upper and lower sides of the top of the first frame 1, realizing the stable connection between the guide rail 22 and the first frame 1, and providing support for the movement of the guide rail 22 under external force. In order to control the movement of the guide rail 22, the first threaded rod 12 is threaded through the end frame 24 or the splicing plate 26. Therefore, when the first motor 11 drives the first threaded rod 12 to rotate forward and backward, the movement of the guide rail 22 can be controlled, realizing the reciprocating movement of the welding component 4 on a certain straight line.

[0041] As Figure 5 , Figure 6As shown, in order to control the reciprocating movement of the welding assembly 4 in another direction to achieve arbitrary movement of the welding assembly 4 on the plane, a connecting mechanism 7 is installed on the guide rail 22. The connecting mechanism 7 includes two second pulleys 71 distributed vertically and two side plates 72 distributed horizontally. The second pulley 71 is distributed between the two side plates 72, and the end of the central axis connected to the second pulley 71 is inserted into the side plates 72 by bolts. At the same time, the two second pulleys 71 are distributed on the upper and lower sides of the guide rail 22. In addition, a support mechanism 6 is installed below the side plates 72. A second threaded rod 21 is provided on the side of the guide rail 22 and is threaded through the side plates 72. The end of the second threaded rod 21 is connected to the power output shaft of the fourth motor. Therefore, when the fourth motor is working and drives the second threaded rod 21 to rotate forward and backward, it can drive the support mechanism 6 to reciprocate along the length of the guide rail 22. Because the guide rail 22 is arranged perpendicular to the first frame 1, the first motor 11 and the fourth motor can cooperate to control the movement of the welding assembly 4 on the horizontal plane.

[0042] like Figure 5 As shown, in order to control the lifting and lowering of the welding assembly 4 and ensure that the support mechanism 6 is stably installed below the connecting mechanism 7, the support mechanism 6 includes a second telescopic cylinder 61, and the welding assembly 4 is installed below the second telescopic cylinder 61. A connecting plate 73 is provided below the two side panels 72 and connected by bolts. The bottoms of the two connecting plates 73 are connected by bolts and inserted into the bottom plate 74. The top of the second telescopic cylinder 61 is connected to the bottom plate 74. When the second telescopic cylinder 61 is stably installed, the height of the welding assembly 4 can be adjusted by extending and retracting the second telescopic cylinder 61, providing support for completing the welding process of the micro switch through the welding assembly 4.

[0043] like Figure 9 As shown, in order to complete the welding process of the micro switch through the welding assembly 4, the welding assembly 4 includes a bracket 8 and a welding mechanism 9. The welding mechanism 9 is provided with at least two symmetrical groups. The two groups of welding mechanisms 9 are installed below the bracket 8. The bracket 8 is mounted on the vertical rod 62, and the vertical rod 62 is installed on the bottom of the second telescopic cylinder 61 through the top plate 66. At the same time, the second telescopic cylinder 61 is inverted. Therefore, when the second telescopic cylinder 61 is extended and retracted, the height of the two groups of welding mechanisms 9 can be adjusted to provide support for completing the welding process of the micro switch through the welding mechanism 9.

[0044] like Figure 11 、 Figure 11As shown, specifically, the welding mechanism 9 includes a vertical plate 93, which is provided with strip holes 932, and the strip holes 932 are arranged along the height direction of the vertical plate 93. Two sets of fixed arc plates 94 and clamping arc plates 95 connected by bolts are provided on the side of the vertical plate 93. The two sets of fixed arc plates 94 and clamping arc plates 95 are respectively provided on both sides of the vertical plate 93. The two sets of fixed arc plates 94 and clamping arc plates 95 are respectively penetrated by a soldering iron tip 92 and a guide tube 91. The bottoms of the soldering iron tip 92 and the guide tube 91 are oriented in an intersecting direction. The bottom of the solder wire wound on the wire feeding mechanism 3 is provided through the guide tube 91. Therefore, when heated by the soldering iron tip 92, the solder wire melts and drips onto the pins of the micro switch. After the solder wire solidifies, the micro switch is stably installed.

[0045] like Figure 12 As shown, in order to adjust the tilt of the soldering iron tip 92 and the guide tube 91 as needed, a first clamping plate 96 and a second clamping plate are fixedly installed on one side of the bottom of the vertical plate 93. The second clamping plate is fixedly mounted on the vertical plate 93, and the first clamping plate 96 is plugged into the vertical plate 93. A fixed arc plate 94 is installed in the space formed by the first clamping plate 96 and the second clamping plate via bolts. The friction force then controls a set of fixed arc plates 94 and clamping arc plates 95 to maintain a certain tilt angle. Two third clamping plates are connected on both sides of the middle of the vertical plate 93. The ends of the two third clamping plates are plugged into the vertical plate 93. Another fixed arc plate 94 is installed between the two third clamping plates, thereby maintaining the fixed arc plates 94 and the clamping arc plates 95 at a certain tilt angle.

[0046] like Figure 10 As shown, to stably mount the welding mechanism 9 below the bracket 8, the bracket 8 includes a support frame 81 and a lifting tube 88. The support frame 81 is configured as a T-shaped structure. The lifting tube 88 is connected to the support frame 81 via a bearing and is sleeved onto the vertical rod 62. Sliding slots 87 are provided on the lower side of the support frame 81, and an adjustment screw is provided inside each sliding slot 87. A sliding block 931 is fixedly mounted on the top of the vertical plate 93. The sliding block 931 is mounted in the sliding slot 87 of the support frame 81, and the adjustment screw thread extends through the sliding block 931. Therefore, the cooperation between the sliding slot 87 and the sliding block 931 ensures that the vertical plate 93 is stably mounted below the support frame 81. The position of the welding mechanism 9 relative to the support frame 81 can be adjusted by rotating the adjustment screw. The tilt angle of the soldering iron tip 92 and the guide tube 91 can be adjusted, providing convenient adaptation to micro switches of different sizes.

[0047] like Figure 9 、 Figure 10As shown, in order to be able to adjust the position of the welding mechanism 9 as needed and adapt to different working conditions, the welding assembly 4 also includes a third motor 41, which is mounted upside down on the vertical rod 62. A gear is provided on the power output shaft of the third motor 41, and the gear is engaged with the external gear 82 mounted on the top of the support frame 81. Then, under the operation of the third motor 41, the bracket 8 can be controlled to rotate around the central axis to synchronously adjust the positions of the two sets of welding mechanisms 9. The above-mentioned first motor 11 and third motor 41 can be set as servo motors, stepper motors, etc.

[0048] like Figure 10 As shown, to ensure stable installation of the industrial camera 5, a fixing plate is fixed to the end of the support frame 81. A clamping plate 85 is installed on the side of the fixing plate via bolts. A support plate 84 is installed between the fixing plate and the clamping plate 85 to press against the support plate 84. The support plate 84 is connected to the industrial camera 5. The support plate 84 is controlled to maintain a certain state under the action of friction, thereby ensuring stable installation of the industrial camera 5.

[0049] In addition, a snap groove 83 and a snap column 86 are respectively provided on the contact surfaces of the clamping plate 85 and the support frame 81. The central angle of the snap groove 83 is greater than 180°, and the snap column 86 is installed in the snap groove 83 to realize the movable installation of the clamping plate 85, and provide support for controlling the clamping plate 85 and the fixed plate to press against the support plate 84 under the action of the bolt.

[0050] like Figure 8 As shown, to enable the feeding of solder wire, the wire feeding mechanism 3 includes a second motor 32 and a take-up reel 31. The take-up reel 31 is sleeved on the second motor 32. A connecting disc 33 fixedly mounted at the end of the central axis of the second motor 32 is connected to the connecting mechanism 7. When the second motor 32 is in operation, the take-up reel 31 is controlled to rotate, and the solder wire wound on the take-up reel 31 is moved to complete the welding wire feeding process. The second motor 32 is configured similarly to the hub motor of an electric bicycle. That is, when the second motor 32 is stably mounted relative to the connecting mechanism 7, it can control the rotation of the take-up reel 31, similar to the control of the wheel hub rotation by a hub motor mounted on the frame of an electric bicycle.

[0051] In order to receive information from the industrial camera 5 and control the operation of the motor and soldering tip 92, the electrical control box 13 needs to be equipped with at least a main control device, an image acquisition and processing module, a motor control module, a soldering tip control module, input and output interface devices, a communication module, a power supply module, etc.

[0052] The main control device includes an industrial computer or programmable logic controller (PLC). Industrial computers have powerful computing capabilities and rich software resources, enabling them to run complex image analysis algorithms and control programs. By installing appropriate image acquisition and motion control cards, they can control industrial cameras and motors, making them suitable for scenarios requiring high-level image analysis and processing and complex control logic. Programmable logic controllers (PLCs) offer high reliability and strong anti-interference capabilities, enabling stable operation in harsh industrial environments. They feature a wide range of input and output interfaces, enabling convenient connection to devices such as industrial cameras and motor drivers. Precise control of motors and soldering iron tips can be achieved through the programming of logic programs. PLCs are a more suitable choice for applications with relatively simple control logic and high reliability requirements.

[0053] The image acquisition and processing module includes an image acquisition card and image processing software. The image acquisition card is used to capture image data captured by industrial cameras and transmit it to the main control device for analysis and processing. Select an acquisition card with the appropriate interface type (such as USB, GigE, or Camera Link) to ensure compatibility with the industrial camera. The image processing software, installed on an industrial computer or PLC with image processing capabilities, analyzes, identifies, and measures the captured images. By programming algorithms, it can achieve functions such as locating target objects, detecting defects, and measuring dimensions, providing a basis for subsequent control decisions.

[0054] The motor control module includes a motor driver and an optional motion control card. The motor driver drives the motor according to control signals from the main control device. Drivers can be categorized as DC motor drivers, AC motor drivers, and stepper motor drivers, depending on the type of motor being used. Drivers offer a variety of control modes, such as speed control, position control, and torque control, to meet diverse application requirements. If an industrial computer is used as the main control device, the motion control card can be inserted into the computer's expansion slot to achieve precise motion control of the motor. It provides a rich set of motion control functions and interfaces, allowing for easy connection to the motor driver, enabling complex motion control functions such as multi-axis linkage and interpolation.

[0055] The soldering iron tip control module includes a temperature controller, relays, or solid-state relays. The temperature controller precisely controls the tip's temperature. It uses a thermocouple or other temperature sensor to monitor the tip's temperature in real time and feeds the temperature signal back to the temperature controller. The controller automatically adjusts the tip's heating power based on the set temperature, ensuring the tip maintains a stable temperature during operation. A relay or solid-state relay controls the power supply to the tip. The temperature controller controls the tip's heating circuit by controlling the relay's or solid-state relay's on / off state. Solid-state relays offer advantages such as a lack of contacts, fast switching speed, and long life, making them suitable for high-frequency switching applications. Conventional relays, on the other hand, have larger contact capacity and can handle higher currents.

[0056] In addition, a drag chain can be provided to provide communication power supply and other functions for the welding assembly 4 when it moves. The above embodiment can be installed on the conveyor 14 according to needs to realize batch welding processing of micro switches.

[0057] Example 2

[0058] like Figure 5 、 Figure 6 As shown, based on Example 1, in order to be able to use this device to grab the micro switch and place it at the location to be installed, a suction cup 63 is provided at the bottom of the vertical rod 62. The suction cup 63 is connected to the vacuum pump 64 through the air pipe 65. Therefore, under the action of the vacuum pump 64, the pressure of the suction cup 63 can be adjusted to provide support for adsorbing the micro switch and controlling the movement of the welding assembly 4. A connecting frame 75 is fixedly provided at the end below the bottom plate 74, and the vacuum pump 64 is installed at the connecting frame 75. In this case, the length of the first frame 1 is greater than the width of the conveyor 14, and a platform for supporting the regularly distributed micro switches is provided on the side of the first frame 1.

[0059] like Figure 9 As shown, in addition, the welding assembly 4 also includes a first telescopic cylinder 42, which is invertedly installed on the side of the vertical rod 62, and the telescopic end of the first telescopic cylinder 42 is connected to the top of the lifting tube 88. Therefore, the position of the welding mechanism 9 can be adjusted under the action of the first telescopic cylinder 42, which facilitates the suction cup 63 to absorb and transfer the micro switch, and provides support for completing its welding process after the micro switch is stably placed.

[0060] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
