[0002] In electronic welding process, the accurate filling of flux is crucial to ensure the welding quality. The traditional flux filling method is mostly manual operation, using simple containers and tools for filling.

[0035] Working process and principle

[0036] Equipment preparation stage

[0037] The operator first moves the flux precise filling machine to the working position through the handle 102 on the shell assembly 1, and ensures that the equipment is placed stably.

[0038] Open the lock cover part 27 in the flux storage assembly 2, lift the storage tank upper cover 22, and inject the flux into the flux storage tank 21 through the opening at the top. After the injection is completed, close the storage tank upper cover 22 and ensure that the lock cover part 27 is locked in place to prevent the flux from volatilizing and leaking.

[0039] Connect the power supply of the equipment, turn on the power switch 8, at this time the equipment starts the initialization self-check, the touch screen 6 displays the start-up picture and initial state information of the equipment. The operator can check the connection state of each part of the equipment, the initial liquid level detected by the liquid level monitor 25, etc. through the touch screen 6, to ensure that the equipment is in normal preparation state.

[0040] Flux filling stage

[0041] According to the production demand, the operator sets the required flux filling amount, filling speed, etc. through the touch screen 6 or the operation switch 11 on the top of the shell 101. After setting is completed, start the filling program.

[0042] The flux in the flux storage tank 21 is pressurized under the action of the pressure regulating valve 26. The pressure regulating valve 26 adjusts the pressure in the tank according to the set pressure value (which can be adjusted by the pressure regulating valve 10, and the current pressure value is displayed in real time by the pressure gauge 9) to enable the flux to be delivered through the pipeline at a stable pressure. The flux first passes through the first floating joint 23 connected to the upper cover 22 of the storage tank and then flows into the pipeline, and then flows to the flux filling assembly 5.

[0043] In the flux filling assembly 5, the flux enters the filling edge groove 51 from the joint 53. The design of the filling edge groove 51 ensures that the flux can be uniformly and accurately filled to the target position (such as the soldering position of the circuit board, etc.). At this time, the flux monitoring assembly 3 starts to work, and the monitoring camera 31 is fixed on the top of the housing 101 through the mounting bracket 33 and the monitoring camera mounting seat 32 and is located above the filling edge groove 51 to monitor the liquid level change in the filling edge groove 51 in real time.

[0044] As the flux continues to be filled, the liquid level in the flux storage tank 21 gradually decreases. The liquid level monitor 25 monitors the liquid level change in real time and transmits the data to the equipment control system (which can be integrated in the control module of the touch screen 6 or separately arranged). When the liquid level decreases to a certain extent, the touch screen 6 displays a low liquid level warning message to remind the operator to replenish the flux in time, but the device can still continue to work for a period of time to ensure that the current production task is not affected.

[0045] Waste liquid collection stage

[0046] During the filling process, if the flux overflows, splashes, or waste liquid is generated due to other reasons, the waste liquid will flow into the waste liquid collection tank 4 through the integrally formed liquid outlet pipeline 52 on one side of the filling edge groove 51. The waste liquid collection tank 4 is separated from the inside of the housing assembly 1 by the partition plate 103 to prevent the waste liquid from contacting the flux storage assembly 2 and other components, ensuring the safety of the equipment and the cleanliness of the environment.

[0047] The operator can periodically check the liquid level of the waste liquid collection tank 4, and when the liquid level reaches a certain height, the waste liquid collection tank 4 is removed from the housing assembly 1, and the waste liquid is treated according to environmental protection requirements. After treatment, the empty waste liquid collection tank 4 is reinstalled back to the device.

[0048] Device operation monitoring and adjustment stage

[0049] During the entire filling process, the operator monitors the running state of the device in real time through the touch screen 6, including the filling amount, filling speed, current pressure, liquid level change, and working state of each component of the device, etc. If the filling amount is inaccurate, the liquid level abnormally fluctuates, or other problems are found, the operator can adjust at any time through the operation switch 11 or the corresponding function key on the touch screen 6.

[0050] For example, if the filling speed is found to be too fast or too slow, the pressure setting value of the pressure regulating valve 26 can be adjusted through the touch screen 6 to change the flux flow rate; if the monitoring camera 31 detects that the liquid level in the filling edge groove 51 abnormally rises (possibly due to a blocked filling port or other faults that prevent the flux from flowing normally), the touch screen 6 will display an abnormal liquid level alarm message, and the operator can immediately press the emergency stop switch 7 to stop the equipment operation, check and eliminate the fault, and then restart the equipment.

[0051] Device stop and maintenance phase

[0052] When the production task is completed or the device needs to be paused, the operator presses the power switch 8 to turn off the device power. At this time, the device stops flux filling, the pressure regulating valve 26 releases the pressure in the tank, and each component stops working.

[0053] Periodic maintenance of the device includes cleaning components such as the flux storage tank 21 and the filling edge groove 51, checking whether the pipe connections are loose, whether the sensors such as the liquid level monitor 25 and the monitoring camera 31 are working normally, and whether the performance of components such as the pressure regulating valve 26 and the operation switch 11 is good. For consumable parts such as seals, regular replacement is performed according to the service life to ensure that the device is always in good working condition and ready for the next production task.

[0054] The above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and all equivalent technical solutions also belong to the scope of the present application. The patent protection scope of the present application should be defined by the claims.
