Description

Technical Field

[0001] This utility model provides a welding control device for electrostatic sensitive devices, belonging to the field of welding control technology for electrostatic sensitive devices. Background Technology

[0002] Currently, there are special process requirements for soldering electrostatic sensitive devices. For example, when encapsulating and soldering infrared focal plane detectors, the soldering iron needs to be powered off. This requires the soldering operator to repeatedly control the power switch of the soldering iron, frequently switching the power on and off. This affects the soldering efficiency and can easily lead to misoperation after prolonged soldering. Soldering with the power on will generate static electricity, which can damage the detector product. Therefore, there is an urgent need to develop a soldering control device that can improve soldering efficiency and avoid damaging the device. Utility Model Content

[0014] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a welding control device for electrostatic sensitive devices, including a time-on controller 1, a soldering iron power supply 2, and a foot switch 3. The time-on controller 1 is internally equipped with a microcontroller 10, a display module 11, a time setting module 12, and a time relay K1. The signal input terminal of the time relay K1 is connected to the microcontroller 10, the power input terminal of the time relay K1 is connected to the power input terminal of the time-on controller 1, and the power output terminal of the time relay K1 is connected to the power output terminal of the time-on controller 1.

[0015] The microcontroller 10 is also connected to the display module 11 and the time setting module 12 via wires, and the signal input terminal of the microcontroller 10 is connected to the foot switch 3 via a quick-plug aviation socket.

[0016] The power output terminal of the time-on controller 1 is connected to the power input terminal of the soldering iron power supply 2 via a power cable, and the output terminal of the soldering iron power supply 2 is connected to the soldering iron.

[0017] A fuse F1 is also installed between the power input terminal of the time-powered controller 1 and the power input terminal of the time relay K1.

[0018] This utility model controls the on / off switching of the soldering power supply by setting a time relay. The provided time power controller is equipped with a relay switching module, a digital tube display module, and a time setting module. The time power controller is connected to the power input circuit of the soldering iron. After the operator lightly presses the foot switch, the time controller starts timing. When the preset time of the time setting module is reached, the relay K1 is activated, which cuts off the power circuit of the soldering iron and disconnects the power supply to the soldering iron.

[0019] Furthermore, in practical use, the present invention first sets the heating time of the soldering iron (e.g., 1 minute), then steps on the foot switch, and the timer inside the time controller starts counting. At this time, the soldering iron starts heating. When the timer reaches the set time (1 minute), the time relay K1 is controlled to disconnect the power supply to the soldering iron, so that the soldering iron stops heating. At this time, soldering operations can be performed. When the soldering iron needs to be heated again, the foot switch is stepped on again to restart the heating timer.

[0020] Furthermore, to achieve the aforementioned control effect, a microcontroller and a time relay need to be set in the time-powered controller. The corresponding power-on time is set through the time setting module. After the preset time is reached, the microcontroller sends a control signal to the time relay, causing the normally open contact of the time relay to close. By connecting the power output interface of the time-powered controller to the normally closed contact of the time relay, in the closed state where the time relay coil is not energized, the normally closed contact of the time relay outputs power to the soldering iron, which is then energized and heated. After the preset time is reached, the microcontroller sends a signal to the time relay, controlling the normally closed contact of the time relay to open, thus de-energizing the soldering iron.

[0021] This invention, considering portability and safety for field use, provides a time-on-power controller housed in a small powder-coated aluminum profile chassis. The chassis shell is equipped with an ABS plastic insulating panel. To further ensure the reliability of the microcontroller, a highly reliable Delixi JS14S time relay (high-power 20A relay) is selected for control. Furthermore, this invention utilizes a quick-plug aviation socket for the connection between the foot switch and the time-on-power controller chassis to improve stability and lifespan. The welding control device provided by this invention is suitable for welding electrostatic sensitive devices (such as focal plane infrared detectors). During use, a signal is sent to the microcontroller via the foot switch, and the power-on time range of 0.1 seconds to 99 minutes is input via the time setting module. The microcontroller then controls the time relay to operate, thereby controlling the on / off state of the soldering iron power supply.
