Description

Technical Field

[0001] The utility model relates to the technical field of display boards, in particular to a remote digital display circuit for gas shielded welding wire feeding and a display board thereof. Background Art

[0002] Gas shielded welding, also known as metal arc welding (MIG welding), is a welding method that uses an inert gas as a protective atmosphere to prevent the molten metal from coming into contact with oxygen in the air and other adverse environmental factors. This welding method can be semi-automatic or fully automatic and is suitable for a variety of materials, including steel and other metals. In gas shielded welding, the welding area is covered with a layer of inert gas, which helps to reduce oxidation and contamination during the welding process, thereby improving welding quality and efficiency. In the gas shielded welding process, the welding wire is fed into the welding area through a wire feeding mechanism and melted by the action of the arc, combining with the base material to form a weld. During the wire feeding process, a display panel is required to digitally display the wire feeding data, such as the wire feed speed.

[0003] On actual production lines, the wire feeder is installed far from the main machine, about 6-50 meters away. Therefore, during the welding process, workers cannot see the numbers displayed on the main machine when adjusting the current and voltage on the wire feeder.

[0004] And because the wire feeder is only supplied with a 24V working voltage when welding, the preset working current and voltage cannot be seen on the wire feeder when not welding, which affects the subsequent use of the workers. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of the present utility model is to provide a remote digital display circuit and a display panel for gas shielded welding wire feeding, which are used to solve the problem in the prior art that workers cannot see the numbers displayed on the host when adjusting the current and voltage on the wire feeder, and cannot see the preset working current and voltage on the wire feeder when not welding.

[0006] To achieve the above-mentioned and other related purposes, the utility model provides a remote digital display circuit for gas shielded welding wire feeding, comprising a single-chip microcomputer U1, a digital tube module and a power module. The power module is connected to the single-chip microcomputer U1 to provide power supply; the single-chip microcomputer U1 is connected to the digital tube module to drive the digital tube module to display data according to the dynamic operation of the machine;

[0007] The digital tube module includes a first LED digital tube and a second LED digital tube, the first LED digital tube is electrically connected to the single chip computer U1, and the second LED digital tube is connected in series with the first LED digital tube;

[0008] The power module uses a 24V power supply, a double potentiometer is connected to the 24V power supply, and the sliding end of the double potentiometer is connected to the single chip computer U1; the 24V power supply is also connected to a storage capacitor C, and the double potentiometer is connected in parallel with the storage capacitor C.

[0009] In one embodiment of the present invention, a switching voltage regulator U2 is connected to the 24V power supply, and an inductor L is connected in series to the positive electrode of the 24V power supply.

[0010] In one embodiment of the present invention, the dual potentiometer includes a first potentiometer W1 and a second potentiometer W2. The fixed pins of the first potentiometer W1 and the second potentiometer W2 are connected in parallel, and the sliding pins are both connected to the microcontroller U1. The first potentiometer W1 and the second potentiometer W2 are respectively used to adjust the current and voltage of the wire feeder.

[0011] In one embodiment of the present invention, the fixed pins of the first potentiometer W1 and the second potentiometer W2 are both connected to a trimming resistor R1 .

[0012] In one embodiment of the present invention, the energy storage capacitor C is an electrolytic capacitor.

[0013] A remote digital display board for gas shielded welding wire feeding comprises the remote digital display circuit.

[0014] As described above, the remote digital display circuit and display board for gas shielded welding wire feeding of the present invention have the following beneficial effects:

[0015] 1. By setting two LED digital tubes and a double potentiometer connected in series, the double potentiometer can extract the corresponding voltage data at the position of the voltage and current adjustment knob, and then convert the voltage data into the relative welding machine output voltage and current through the single-chip microcomputer U1 and display it on the digital tube to reflect the voltage and current at that time. While the single-chip microcomputer U1 drives the first LED digital tube to display data, the second LED digital tube can synchronously copy the display content of the first LED digital tube. In actual use, the first LED digital tube and the second LED digital tube can be installed separately to realize the synchronous display function of the wire feeder and the host. During the welding process, the worker can see the numbers displayed on the host when adjusting the current and voltage on the wire feeder, thereby improving the wire feeding adjustment effect.

[0016] 2. Since the wire feeder does not have a 24V voltage when not welding, this application adds a large-capacity energy storage capacitor C to the display circuit. This can ensure that the display board can continue to provide working voltage after welding is stopped. The preset welding working voltage and current can still be displayed on the wire feeder, ensuring the speed and quality of subsequent wire feeding, and further improving the wire feeding effect;

[0017] 3. The remote digital display circuit and display board for gas shielded welding wire feeding provided by the utility model, the design of dual LED digital tubes connected in series and dual potentiometers, can copy digital display information and realize the remote synchronous display function of the wire feeder and the host; the design of the energy storage capacitor C can continue to provide the display board working voltage after welding is stopped to display the preset welding working voltage and current, thereby ensuring the speed and quality of subsequent wire feeding and effectively improving the wire feeding effect.

[0023] See also Figure 1 The utility model provides a remote digital display circuit for gas shielded welding wire feeding, including a single-chip microcomputer U1, a digital tube module 1 and a power module 2. The power module 2 is connected to the single-chip microcomputer U1 for providing power supply; the single-chip microcomputer U1 is connected to the digital tube module 1 for dynamically driving the digital tube module 1 to display data according to the machine operation; the power module 2 adopts a 24V power supply, and the 24V power supply is connected to a switching voltage regulator U2. The positive pole of the 24V power supply is connected in series with an inductor L. The inductor L is connected in series with the positive pole of the power supply to further reduce the ripple of the power supply and further ensure the working stability of the single-chip microcomputer U1.

The fixed pins of the first potentiometer W1 and the second potentiometer W2 are both connected to a fine-tuning resistor R1; by setting two LED digital tubes and a dual potentiometer 5 connected in series, the dual potentiometer 5 can extract the corresponding voltage data at the position of the voltage and current adjustment knobs, and then convert the voltage data into the relative welding machine output voltage and current through the single-chip microcomputer U1 and display it on the digital tube to reflect the voltage and current at that time. While the single-chip microcomputer U1 drives the first LED digital tube 3 to display data, the second LED digital tube 4 can synchronously copy the display content of the first LED digital tube 3. In actual use, the first LED digital tube 3 and the second LED digital tube 4 can be installed separately to realize the synchronous display function of the wire feeder and the host. During the welding process, workers can see the numbers displayed on the host at the same time when adjusting the current and voltage on the wire feeder, thereby improving the wire feeding adjustment effect. This remote and synchronous display function helps to promptly detect problems in the wire feeding process, such as unstable wire feeding speed and wire feeding interruptions, so that measures can be taken quickly to adjust or repair them. In addition, by remotely monitoring the wire feeding situation, the continuity and stability of the welding process can be ensured, and downtime caused by wire feeding problems can be reduced, thereby improving overall production efficiency.

[0025] The 24V power supply is also connected to a storage capacitor C, and the dual potentiometer 5 is also connected in parallel with the storage capacitor C. Specifically, the storage capacitor C is an electrolytic capacitor. Since the wire feeder has no 24V voltage when not welding, the present application adds a large-capacity storage capacitor C to the display circuit, which can ensure that the display board working voltage can continue to be provided for about half an hour after welding is stopped. The preset welding working voltage and current can still be displayed on the wire feeder, ensuring the speed and quality of subsequent wire feeding, and further improving the wire feeding effect.
