Description

Technical Field

[0001] The utility model belongs to the technical field of electrical automation, and particularly relates to a wireless current regulating device for a welding machine. Background Art

[0002] A welding machine uses the high-temperature electric arc generated by the instantaneous short circuit of the positive and negative electrodes to melt the solder on the welding electrode and the material to be welded, so as to achieve the purpose of combining the contacted objects, and is widely used in industries such as engineering machinery, ships, and heavy machinery. Most of the existing welding machines adopt wired control, and their current control knobs are on the machine body. However, in the actual welding process, in order to ensure the welding quality, different materials need to use welding electrodes with different diameters and types, and the corresponding current also needs to be selected. Moreover, different welding positions have different requirements for the current. In the actual welding process, the parts to be welded are often several meters or even dozens of meters away from the welding machine. Sometimes, welding operations need to be carried out in narrow environments such as high altitudes, boilers, or pipelines. Usually, the welding operator has to go out to adjust the welding current by himself, or arrange a special person to wait beside the welding machine and follow the instructions of the welding operator to cooperate with the adjustment of the current. The operation is inconvenient and the work efficiency is low. This method increases the labor cost and the working intensity of the welder, cannot meet the requirements of the welding operator in a timely and accurate manner, reduces the welding efficiency, and may also affect the welding quality due to inaccurate transmission of the adjustment command. Content of the Utility Model

[0003] The utility model aims to solve the above problems, and thus provides a wireless current regulating device for a welding machine, which can be adjusted remotely, is convenient and fast, improves work efficiency, adapts to different working conditions, and reduces costs.

[0004] To achieve the above utility model purpose, the utility model provides a wireless current regulating device for a welding machine, which includes a wireless receiver, a relay, a motor, a potentiometer, a control circuit and a remote control inside the welding machine body. A wireless transmitter is arranged inside the remote control, and an increase current button and a decrease current button are arranged on the remote control. The relay is electrically connected to the wireless receiver, the motor is electrically connected to the relay, and the potentiometer is connected to the motor; the wireless receiver receives the signal sent by the wireless transmitter of the remote control, drives the relay to execute through the control circuit, the motor rotates, and drives the potentiometer to work through a gear set.

[0005] Further, the control circuit includes a receiving module 315MHZ, a decoding module SC2262, a driving module AT89C2051 and a relay connected in sequence. After the receiving module 315MHZ receives the signal of the remote control, it is decoded by the decoding module SC2262, and then the driving module AT89C2051 drives the relay to execute.

[0006] Further, the relay includes a first drive circuit relay JQ1 and a second drive circuit relay JQ2. When the first drive circuit relay JQ1 is executed, the DC motor rotates forward, driving the potentiometer to rotate forward through the gear set. When the second drive circuit relay JQ2 is executed, the DC motor rotates backward, driving the potentiometer to rotate backward through the gear set.

[0007] Compared with the prior art, the wireless current adjustment device for the electric welding machine may have the following advantages and improvements:

[0008] (1) Improve work efficiency: Operators do not need to frequently travel back and forth between the welding machine and the welding operation point, which can save time and physical strength, thus improving the overall work efficiency.

[0009] (2) Enhance operation convenience: The wireless adjustment method makes the operation more flexible. Especially in a space-constrained or dangerous environment, it can provide greater convenience and safety.

[0010] (3) Improve welding quality: Real-time and precise control of the current helps to obtain a more stable welding effect and improve the welding quality.

[0011] (4) Adapt to different working conditions: The current can be flexibly adjusted according to the specific welding task and working conditions to better meet various requirements.

[0012] (5) Reduce costs: It reduces the labor input and at the same time reduces the material waste caused by inconvenient operation, which helps to reduce costs.

[0013] (6) Good compatibility: It can be compatible with existing electric welding machines, facilitating transformation and upgrading, and reducing the equipment update cost.

[0014] These advantages and improvements make the wireless current adjustment device for the electric welding machine have great potential in improving the efficiency, quality, and safety of welding operations, and can better meet the requirements of modern welding processes.
