[0033] This utility model primarily addresses the problems of low efficiency, high workload, and inconsistent quality caused by excessive manual intervention in the soldering process of lens zoom motors, focus motors, and interface contacts. It utilizes a control system, a three-way electric cylinder, a rotary motor, an automatic solder feeder, and a soldering iron to achieve fully automated soldering, saving manpower and improving quality. (Refer to...) Figures 1 to 4 The present invention provides an automatic soldering device for internal circuitry of a lens, which is implemented in the following embodiment:

[0034] In some embodiments, an automatic soldering device for internal circuitry of a lens includes a machine base 100, a support assembly, a solder assembly 300, an automatic wire feeding mechanism, a four-axis drive structure 500, a barcode scanning mechanism, and a control system.

[0035] The machine 100 has a horizontally arranged table 110, which is equipped with a QR code including machine type identification information. Each QR code corresponds to different machine type information. Each time the QR code of a different tray 200 is scanned, the different machine type information is switched. Different soldering operation procedures are performed according to different machine type information. This control system can control multiple automatic soldering machines and reduce soldering costs. The QR code is located in a groove in the edge area of ​​the table 110. The surface of the groove is covered with a transparent protective cover, which protects the QR code.

[0036] The support assembly includes a tray 200 disposed on a tabletop 110. A pressure plate 210 is provided on the surface of the tray 200. The pressure plate 210 can be detached from the tray 200 by multiple screws. The pressure plate 210 can help fix the parts to the tray 200. The tray 200 can also be provided with positioning grooves for easy and quick positioning of parts.

[0037] The soldering assembly 300 includes a soldering tip 310 and a solder nozzle 320. The solder nozzle 320 is positioned to the side of the soldering tip 310 via a support member. The soldering tip 310 and the solder nozzle 320 work together to achieve automatic soldering. During the soldering process, the solder nozzle 320 guides the solder wire and delivers it to the soldering point, while the soldering tip 310 heats the solder wire.

[0038] The automatic wire feeding mechanism includes a wire feeding motor, a guide wheel 410, and a guide channel 400. The end of the guide channel 400 extends to the working area of ​​the soldering iron tip 310. One end of the solder wire is wound around the guide wheel 410, and the other end is connected to the guide channel 400 and passes into the solder nozzle 320. As the solder wire is used continuously, the guide wheel 410 rotates continuously. The guide wheel 410 is connected to the output end of the X-axis linear module 510, so that the guide wheel 410 moves in the X-axis and Y-axis directions accordingly with the solder assembly 300, which is conducive to smoothly feeding the solder wire to the solder nozzle 320.

[0039] The three-axis linear module includes:

[0040] X-axis linear module 510: This module is responsible for horizontal (lateral) movement. It is designed to slide smoothly on the Y-axis linear module 520, and the stability and accuracy of the movement are ensured by a precision guide rail and slider structure.

[0041] Y-axis linear module 520: Serving as the reference for the entire system, the Y-axis linear module 520 is fixedly mounted on the welding machine 100, providing longitudinal movement perpendicular to the X-axis. Its robust structure ensures good positioning accuracy even during prolonged operation.

[0042] Z-axis linear module 530: The Z-axis linear module 530 is mounted on the X-axis linear module 510 and is responsible for vertical (up and down) movement. By adjusting the height of the Z-axis, the distance between the solder assembly 300 and the workpiece can be precisely controlled to adapt to soldering requirements of different heights and depths.

[0043] Rotary drive motor 540: This motor is fixedly mounted at the end of the Z-axis linear module 530. A high-performance servo motor or stepper motor is selected to ensure the accuracy of rotation and the controllability of speed. The output shaft of the motor is connected to the solder assembly 300 via a coupling or direct connection.

[0044] Solder assembly 300: Solder assembly 300 includes a soldering gun, a solder wire supply system, and a temperature control system, used to perform the actual soldering operation. Driven by a rotary drive motor 540, solder assembly 300 can rotate freely within a 360-degree range, enabling soldering of workpieces at any angle.

[0045] System operation process:

[0046] Before welding begins, the welding path and parameters, including the travel distance, speed, acceleration, and rotation angle of each axis, are input through the control system. The control system first moves the solder assembly 300 above the initial position of the target workpiece using the Y-axis linear module 520. Next, the X-axis linear module 510 and Z-axis linear module 530 work together to precisely adjust the solder assembly 300 directly above the welding point and to a suitable welding height. The rotary drive motor 540 starts, adjusting the orientation of the solder assembly 300 according to a preset angle to suit the specific welding area of ​​the workpiece. Finally, the solder assembly 300 begins the welding operation. Simultaneously, each axis can continue to be fine-tuned as needed to ensure welding quality and accuracy.

[0047] The four-axis drive structure 500 greatly enhances the flexibility and automation of welding operations, enabling it to handle welding tasks with complex shapes and positions. Through precise control, it achieves high-quality and high-efficiency welding, reduces manual intervention, and improves production efficiency and product consistency.

[0048] The X-axis linear module 510, Y-axis linear module 520, and Z-axis linear module 530 are all equipped with slide rails to improve sliding stability. Each of the X-axis linear module 510, Y-axis linear module 520, and Z-axis linear module 530 includes a servo motor and a ball screw, which are connected by a drive mechanism. The rotary drive motor 540 is a stepper motor with an encoder, and the output end of the stepper motor is connected to the solder assembly 300.

[0049] In some other embodiments, the four-axis drive structure 500 includes an X-axis linear module 510, a Y-axis linear module 520, a Z-axis linear module 530, and a rotary drive motor 540. The X-axis linear module 510 is fixedly connected to the machine base 100, the Y-axis linear module 520 is slidably disposed on the X-axis linear module 510, the Z-axis linear module 530 is slidably disposed on the Y-axis linear module 520, and the rotary drive motor 540 is fixed to the end of the Z-axis linear module 530 and its output shaft is connected to the solder assembly 300.

[0051] The control system includes a main control chip, a memory, and a communication interface. The memory stores welding parameter templates for multiple machine types. The communication interface is electrically connected to the scanning mechanism, the four-axis drive structure 500, and the automatic wire feeding mechanism. The scanning mechanism scans QR codes, and the control system identifies the machine type information based on the QR codes. Then, based on the control template program corresponding to the machine type information, it controls the automatic wire feeding mechanism and the four-axis drive structure 500 to weld the parts located on the tray 200.

[0052] Furthermore, the control system includes an industrial touch screen and a graphics processing module integrated at the front end of the machine 100. A camera is also installed on the frame, which is aimed at the tray 200. The industrial touch screen displays the movement trajectory of the solder assembly 300 and the grid of solder joint coordinates in real time. The industrial touch screen is electrically connected to the communication interface.

[0053] The automatic soldering equipment for internal lens circuitry also includes a tilt adjustment structure comprising three height-adjustable support components. A tray 200 has a base plate, and the tray 200 is detachable from the base plate. The support components are triangularly distributed along the bottom surface of the base plate. Each support component includes a lifting rod and a fixed seat. The fixed seat is located on the table 110. The upper end of the lifting rod is hinged to the bottom of the base plate. The fixed seat has a vertically extending lifting groove, and the lifting rod slides vertically into the lifting groove. A nut sleeve is rotatably mounted on the fixed seat.
