[0021] In large-scale production of existing antenna devices, scenarios requiring high reliability or precision structures, automated soldering equipment is used to solder multiple wires to the same PCB board. This necessitates accurate identification of the solder joints on the PCB board by the automated soldering equipment to ensure a stable electrical connection between the multiple wires and the PCB board. In antenna devices, the PCB board to be soldered may have a planar or three-dimensional structure, requiring the automated soldering equipment to accurately locate the solder joints along the X, Y, and Z axes to ensure soldering accuracy. However, existing automated soldering equipment suffers from inaccurate identification of solder joints.

[0022] To solve the above problems, refer to Figure 1 , Figure 4 and Figure 5 This utility model proposes an automatic soldering device, which includes: Control device 10; Solder assembly 20, the controlled end of which is electrically connected to the control device 10; the solder assembly 20 is used to receive corresponding solder control signals and perform solder wire heating and soldering actions; The mobile device 30 is electrically connected to the control device 10; the mobile device 30 is connected to the solder assembly 20; the mobile device 30 is used to receive corresponding movement control signals and drive the solder assembly 20 to move. Displacement detection device 40, which is electrically connected to the control device 10; displacement detection device 40 is used to detect the displacement of the solder assembly 20 and output a displacement detection signal to the control device 10; The control device 10 is used to receive the displacement detection signal and regulate the amount of movement of the solder assembly 20 driven by the moving device 30.

[0023] In this embodiment, the control device 10 can be implemented using FPGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), SOC (System on Chip), etc. The control device 10 also includes a corresponding memory to store the corresponding soldering motion trajectory and soldering parameters, thereby enabling soldering of the equipment to be soldered when the automatic soldering equipment is in operation. In this embodiment, the soldering assembly 20 includes heating components such as a soldering iron tip. The controlled end of the soldering assembly is electrically connected to the control device 10 to heat the solder wire upon receiving a soldering control signal, thereby completing the soldering action.

[0024] In this embodiment, the moving device 30 can be implemented using a servo motor, stepper motor, synchronous belt, ball screw, linear guide, etc. The motor in the moving device 30 is electrically connected to the control device 10, thereby driving the solder assembly 20 to move when a corresponding movement control signal is received, in order to solder different areas of the target object.

[0025] Optionally, the mobile device 30 includes: A servo motor is electrically connected to the control device 10; the servo motor is used to receive drive control signals and provide rotational power. A timing belt is connected to the servo motor; the timing belt is used to drive the solder assembly 20 to move by the rotational motion of the servo motor. A linear guide rail is fixedly connected to the frame and provides linear motion guidance for the solder assembly 20.

[0026] Understandably, servo motors are more suitable for automatic soldering equipment than stepper motors because they offer significant advantages in precision, speed, torque control, responsiveness, reliability, and long-term stability. Specifically, stepper motors use open-loop control; sudden load changes, such as guide rail jamming or increased resistance, can lead to missed steps—failing to reach the commanded position without system detection. This results in solder joint misalignment, causing issues like cold solder joints, bridging, and missing solder. Servo motors, on the other hand, provide real-time position feedback via an encoder, allowing the controller to detect and correct deviations, ensuring accurate positioning at every step. Furthermore, automatic soldering machines often require rapid movement between multiple solder joints; servo motors maintain stability at high speeds, reducing cycle time. Stepper motors experience significant torque drop at high speeds and are prone to vibration, limiting their maximum operating speed. The inherent vibration of stepper motors during operation can cause solder jitter, affecting solder joint quality. Servo motors, driven by sinusoidal waves, offer smooth motion without resonance points, making them suitable for precision soldering.

[0027] In this embodiment, the servo motor provides precise rotational power, accurately controlling the speed, angle, and torque according to the drive control signal input from the control device 10. The synchronous belt transmits the rotational motion of the servo motor to the solder assembly 20, engaging with the pulley through its teeth. The linear guide provides high-precision linear motion guidance for the solder assembly 20, bearing radial and lateral loads to ensure smooth, wobbly, and low-friction movement. Specifically, the servo motor is mounted at one end of the frame, and its output shaft is equipped with a drive synchronous pulley. The two ends of the synchronous belt are wound around the drive pulley and the driven pulley, respectively, forming a closed-loop transmission. The solder assembly 20 is securely connected to a section of the synchronous belt via a belt clip or aluminum alloy. When the motor rotates, it drives the synchronous belt, pulling the slide table along the linear guide. The slider on the linear guide is fixed to the slide table, ensuring that it can only move linearly along the guide direction without deviation or wobbling.

[0028] In this embodiment, the displacement detection device 40 can be implemented using a magnetic scale sensor, a potentiometer-type displacement sensor, or the like. The displacement detection device 40 needs to be specifically positioned in the corresponding area of ​​the automatic soldering equipment, depending on the selected type. For example, a magnetic scale sensor needs to be positioned on a linear guide rail to detect the amount of movement of the solder assembly 20 on the linear guide rail. The displacement detection device 40 detects the displacement of the solder assembly 20 and outputs a corresponding displacement detection signal to the control device 10. The control device 10 then confirms whether the displacement of the solder assembly 20 driven by the moving device 30 corresponds to the displacement in the preset soldering program by verifying the displacement detection signal, thereby calibrating the movement of the solder assembly 20 driven by the moving device 30.

[0029] Optionally, the displacement detection device 40 is a magnetic scale sensor, which is disposed on the linear guide rail and detects the amount of movement of the solder assembly 20 on the linear guide rail.

[0030] Understandably, a magnetic scale sensor is a non-contact displacement measuring device based on the principle of magnetism, mainly used to accurately measure the position, speed and direction of linear or rotational motion.

[0031] The magnetic scale sensor mainly consists of two parts: a magnetic scale and a reading head. The magnetic scale is a magnetic strip or bar with equally spaced magnetized regions. Its surface is periodically magnetized with alternating N and S poles, forming a magnetic grating. It can be a steel strip, a flexible magnetic strip, or a rigid magnetic scale, and is mounted on a fixed reference point of a moving part. The reading head is mounted on the moving part, maintaining a small gap with the magnetic scale for non-contact detection. It contains a magnetic sensing element and a signal processing circuit. Specifically, the magnetic poles on the magnetic scale are arranged in a regular periodic pattern, equivalent to a magnetic scale, with each period corresponding to a position encoding unit. When the reading head moves along the magnetic scale, its internal magnetic sensing element senses the periodic changes in the magnetic field strength and direction. Hall effect elements or magnetoresistive elements convert these magnetic field changes into sine and cosine electrical signals. The signal processing circuit within the reading head amplifies, shapes, and subdivides the original sine / cosine signals. By calculating the phase difference between the two signals, the direction of motion can be determined; by accumulating the number of pulses, the displacement can be calculated. The magnetic scale sensor detects the changes in the magnetic field generated by the periodic magnetization of the magnetic scale, converts them into electrical signals using a magnetic sensitive element, and then calculates the displacement and direction of motion.

[0032] In this embodiment, the control of the servo motor is essentially a closed-loop control system, requiring real-time position feedback to correct the deviation between the actual position and the commanded position. The magnetic scale provides high-precision, real-time linear displacement feedback signals, which can be connected to a servo driver or motion controller to form a complete closed-loop control. The automatic soldering equipment needs precise control of the motion trajectory of each axis (X, Y, Z) to ensure that the soldering assembly 20 runs along a preset path. The magnetic scale is installed on each linear guide rail to directly measure the actual displacement of the soldering assembly 20, avoiding inaccurate positioning caused by mechanical transmission errors (such as lead screw backlash or belt slippage). By installing magnetic scales on each of the X, Y, and Z axes, the scales are fixed to the linear guide rails, and the reading head is installed on the moving parts. The reading head outputs A / B phase incremental signals or absolute signals. The signals are connected to the encoder feedback interface of the motion controller or servo driver. The control device 10 compares the commanded position with the actual position fed back by the magnetic scale in real time, dynamically adjusting the servo motor output to achieve high-precision trajectory tracking.

[0033] This invention, by employing an automatic soldering device, can effectively improve the accuracy of automatic soldering. The automatic soldering device includes a control device 10, a soldering assembly 20, a moving device 30, and a displacement detection device 40. The control device 10 stores a preset soldering program to control the moving device 30 to drive the soldering assembly 20 to perform targeted soldering on the target on the soldering table. The displacement detection device 40 further confirms the displacement of the moving device 30. The control device 10 confirms whether the displacement of the moving device 30 driving the soldering assembly 20 corresponds to the displacement in the preset soldering program by verifying the displacement detection signal output by the displacement detection device 40, thereby calibrating the movement of the moving device 30 driving the soldering assembly 20.

[0034] refer to Figure 2 In one embodiment of this utility model, the mobile device 30 includes: The first moving device 31 is electrically connected to the control device 10; the first moving device 31 is used to receive the corresponding X-axis movement control signal and drive the solder assembly 20 to move on the X-axis. The second moving device 32 is electrically connected to the control device 10; the second moving device 32 is used to receive the corresponding Y-axis movement control signal and drive the solder assembly 20 to move on the Y-axis. The third moving device 33 is electrically connected to the control device 10; the third moving device 33 is used to receive the corresponding Z-axis movement control signal and drive the solder assembly 20 to move on the Z-axis.

[0035] In this embodiment, multiple moving devices 30 are provided to drive the solder assembly 20 in different directions in space. It is understood that the solder joints on the antenna device may not all be on the same horizontal plane. Therefore, to achieve comprehensive soldering of the solder joints on the antenna device, the moving devices 30 need to be able to drive the solder assembly 20 to move in three-dimensional space. Specifically, by providing a first moving device 31, a second moving device 32, and a third moving device 33, the solder assembly 20 is driven to move along the X, Y, and Z axes.

[0036] Furthermore, the displacement detection device 40 includes: A first displacement detection device 41 is electrically connected to the control device 10; the first displacement detection device 41 is used to detect the displacement of the first displacement detection device 41 on the X-axis and output a first displacement detection signal to the control device 10. The second displacement detection device 42 is electrically connected to the control device 10; the second displacement detection device 42 is used to detect the displacement of the second displacement detection device 42 on the Y-axis and output a second displacement detection signal to the control device 10. The third displacement detection device 43 is electrically connected to the control device 10; the third displacement detection device 43 is used to detect the displacement of the third displacement detection device 43 on the Z-axis and output a third displacement detection signal to the control device 10.

[0037] In this embodiment, to detect the movement of the solder assembly 20 driven by the moving device 30 in different directions, it is necessary to set up a displacement detection device corresponding to the number of moving devices 30. The positions of the displacement detection devices also need to correspond to each moving device 30 to ensure that the displacement detection device 40 can accurately detect the amount of movement of the solder assembly 20 driven by each moving device 30 in the corresponding direction. It is understood that, as described above, the moving device 30 includes a first moving device 31, a second moving device 32, and a third moving device 33. Therefore, the displacement detection device is correspondingly provided with a first displacement detection device 41, a second displacement detection device 42, and a third displacement detection device 43 to detect the movement of the solder assembly 20 along the X-axis, Y-axis, and Z-axis, and output corresponding first displacement detection signals, second displacement detection signals, and third displacement detection signals.

[0038] refer to Figure 3 In one embodiment of the present invention, the automatic soldering equipment further includes a parameter input device 50, which is electrically connected to the control device 10; the parameter input device 50 is used to input a corresponding parameter signal to the control device 10 when triggered.

[0039] In this embodiment, the required soldering points and methods differ for different antenna devices. Therefore, the user needs to adjust the parameters of the automatic soldering equipment accordingly so that it can perform targeted soldering for different antenna devices. Furthermore, when parameter errors exist during the soldering of antenna devices, the automatic soldering equipment can adjust the parameters by triggering the parameter input device 50.

[0040] Optionally, the parameter input device 50 includes: A triggering component is electrically connected to the control device 10; the triggering component is used to input a corresponding parameter signal to the control device 10 when triggered. The display component has a first end electrically connected to the trigger component and a second end electrically connected to the control device 10; the display component is used to receive and display the parameter signal.

[0041] In this embodiment, the triggering component can be implemented using a touchscreen, a button panel, or the like. The display component can be implemented using a display screen.

[0042] refer to Figure 3 In one embodiment of the present invention, the automatic soldering equipment further includes a fume purification device 60, which is electrically connected to the control device 10; the fume purification device 60 is disposed on the periphery of the soldering assembly 20; the fume purification device 60 is used to absorb fumes when the soldering assembly 20 is working.

[0043] It is understandable that automatic soldering equipment produces harmful fumes during soldering, which typically contain rosin, metal particles, etc. Therefore, to prevent these harmful fumes from spreading into the workshop where the automatic soldering equipment is located, a corresponding fume extraction device 60 needs to be designed to absorb the fumes. This fume extraction device 60 can be implemented using a small fan and activated carbon or HEPA filters. By being installed around the solder assembly 20, it absorbs the fumes generated by the solder assembly 20 during the heating and soldering of the solder wire.

[0044] refer to Figure 3 In one embodiment of the present invention, the automatic soldering equipment further includes a solder wire pushing component 70, which is electrically connected to the control device 10 and connected to the soldering component 20; the solder wire pushing component 70 is used to push solder wire when the soldering component 20 is working.

[0045] In this embodiment, the solder wire pushing component 70 can be implemented using a stepper motor and a corresponding solder wire guide rail. By receiving the stepper motor control signal output by the control device 10, the stepper motor is controlled to push the solder wire when the soldering component 20 is working, so that the soldering component 20 can perform soldering of the solder joint.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
