[0002] When welding thick plates, welding robots on the market often have problems with inaccurate material feeding or assembly of the workpiece, and the arc starting and ending points are inaccurate, which will cause the weld to deviate. In order to ensure that the weld of the robot is always in the actual weld position, the robot's wire positioning function is required to find the welding starting and ending points of the weld.

[0003] At present, the devices that cooperate with the positioning function of the robot generally adopt low-voltage positioning devices (voltage varies from DC 24V-50V), which generally have the following problems:

[0004] 1. Due to the sensitivity problem of low pressure, the positioning speed is slower than that of high pressure positioning;

[0005] 2. When low-pressure positioning is seriously contaminated by oil, rust, or oxide scale, the positioning may be inaccurate.

[0006] 3. Low-voltage positioning will cause the welding wire to bend, resulting in inaccurate positioning. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies in the above-mentioned background technology and to provide a high-voltage positioning plate and a high-voltage positioning device which can be used in conjunction with a welding robot.

[0008] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

The power supply circuit transforms, rectifies and stabilizes the power supply to provide a working DC power supply for the entire circuit board. When the welding robot inputs a start signal through the robot signal interaction module, the contactor control circuit starts to work and sends a control signal to the contactor control module to disconnect the output of the contactor. At the same time, the positioning start control circuit works to check whether the feedback signal of the contactor returned by the contactor control module is disconnected. After checking that it is disconnected, the positioning start execution circuit is controlled to output the processed high-voltage current to the high-voltage output module after passing through the positioning contact sampling unit;

[0012] The high-voltage output module of the high-voltage positioning board of the present invention can ultimately output high-voltage direct current with a voltage of 300V-500V, and the above-mentioned hardware modules and control circuits can be implemented using existing hardware modules and circuits, so they will not be described in detail here.

[0021] When the high-voltage positioning device of the present invention is in use, the positive input unit and the negative input unit are respectively connected to the positive output and the negative output of the welding machine. The positive output unit outputs current to the welding wire of the welding robot, and the negative output unit outputs current to the workpiece. Specifically, the positive and negative welding currents output by the welding machine to the high-voltage positioning device pass through the high-power contactor contacts of the contactor unit, and the positive current is output to the welding wire of the robot through the positive output unit, and the negative current is output to the workpiece through the negative output unit. When there is no positioning or welding, the contactor contacts of the contactor unit are energized, and the welding current The input unit of the current input and output unit can be normally output to the output unit after passing through the contactor of the contactor unit; when the positioning is started, the contactor contacts of the contactor unit are disconnected, the input unit of the current input and output unit is disconnected from the output unit, and the positive and negative welding cables of the welding machine are no longer connected to the welding wire and the workpiece. After disconnection, the high-voltage positioning board outputs the high-voltage positive current to the positive output unit of the current input and output unit, and then outputs it to the welding wire of the welding robot, and the high-voltage positioning board outputs the high-voltage negative current to the negative output unit of the current input and output unit and then outputs it to the workpiece.

[0040] Preferably, in this embodiment, the hardware module further includes a front panel display interaction module 113 , and the front panel display interaction module 113 is connected to the signal amplification and stabilization circuit 111 and the positioning start control circuit 109 .

[0041] The working principle of the high-voltage positioning board 100 of the present invention is as follows: after the power supply enters the high-voltage positioning board 100 through the power supply input module 101, the power supply is first boosted to the required voltage through the boost, rectification and voltage stabilization circuit 105, and then rectified and stabilized.

[0044] Embodiment 2

[0045] A high-voltage positioning device 200, such as Figure 2 As shown, it includes the high-voltage positioning board 100 of the first embodiment and several hardware units, and the hardware units include a power supply unit 201, a robot signal interaction unit 202, a current input and output unit 203, a contactor unit 204, and a front panel display interaction unit.

[0046] The power supply unit 201 is connected to the power supply input module 101 of the high-voltage positioning board 100 for providing power. In this embodiment, a filter 210 and an air switch 211 are further connected between the power supply unit 201 and the power supply input module 101 .

[0047] The robot signal interaction unit 202 is connected to the robot signal interaction module 102 of the high-voltage positioning board 100, and is used to realize signal interaction with the welding robot; including the positioning start signal transmitted by the welding robot to the high-voltage positioning device 200 and the positioning feedback signal transmitted by the high-voltage positioning device 200 to the welding robot;

[0048] The current input and output unit 203 is connected to the high voltage output module 104 of the high voltage positioning board 100 through the contactor unit 204, and the contactor unit 204 is used to control the on and off of the current input and output unit 203;

[0049] The front panel display interaction unit is connected to the front panel display interaction module 113, and is used to display the status of the high-voltage positioning device 200. For example, when the positioning contact sampling unit detects that the welding wire of the welding robot is in contact with the workpiece, the detection signal is amplified and stabilized through the signal circuit, and then output to the front panel display interaction module and further displayed by the front panel display interaction unit.

[0050] Specifically, in this embodiment, the current input and output unit 203 includes a positive input unit 2031, a negative input unit 2032, a positive output unit 2033, and a negative output unit 2034; the contactor unit 204 includes two contactors, namely a first contactor 2041 and a second contactor 2042, and the two contactors are respectively connected to the high-voltage output module 104 of the high-voltage positioning board 100. The three contacts of the contactors are connected in parallel by installing a three-phase parallel board on the two contactors to increase the current passing through. The input end of the first contactor 2041 is connected to the positive input unit 2031, the output end of the first contactor 2041 is connected to the positive output unit 2033, the input end of the second contactor 2042 is connected to the negative input unit 2032, and the output end of the second contactor 2042 is connected to the negative output unit 2034;

[0051] When the high-voltage positioning device 200 of the present invention is in use, the positive input unit 2031 and the negative input unit 2032 are respectively connected to the positive output and the negative output of the welding machine, the positive output unit 2033 outputs current to the welding wire of the welding robot, and the negative output unit 2034 outputs current to the workpiece. Specifically, the positive and negative welding currents output by the welding machine to the high-voltage positioning device 200 pass through the high-power contactor contacts of the contactor unit 204, and the positive current is output to the welding wire of the robot through the positive output unit 2033, and the negative current is output to the workpiece through the negative output unit 2034. When there is no positioning or welding, the contactor contacts of the contactor unit 204 are energized, and the welding is performed. The current can normally pass through the input unit of the current input and output unit 203 and then be output to the output unit after passing through the contactor of the contactor unit 204; when the positioning is started, the contactor contacts of the contactor unit 204 are disconnected, the input unit of the current input and output unit 203 is disconnected from the output unit, and the positive and negative welding cables of the welding machine are no longer connected to the welding wire and the workpiece. After the disconnection, the high-voltage positioning board 100 outputs the high-voltage positive current to the positive output unit 2033 of the current input and output unit 203, and then outputs it to the welding wire of the welding robot, and the high-voltage positioning board 100 outputs the high-voltage negative current to the negative output unit 2034 of the current input and output unit 203 and then outputs it to the workpiece.

[0052] Specifically, in this embodiment, the front panel display interaction unit includes an indicator light, a buzzer 208, and a test button 209, which can be used to timely display the working status of the high-voltage positioning device 200. For example, the buzzer 208 can be used to prompt that the high-voltage positioning device 200 is working under high voltage. Among them, the indicator lights include a power indicator light 205, a positioning start light 206, and a positioning success light 207 (that is, the welding wire is in contact with the workpiece). The operation of the entire front panel display interaction unit is specifically controlled by the high-voltage positioning board 100.

[0053] It can be seen that the main functions of the high-voltage positioning board 100 of this embodiment are to connect / disconnect the contactor, boost and stabilize the power supply, output high voltage, process the front panel indicator lights, buttons, and buzzer 208, detect whether the positive and negative poles of the output high voltage are in contact, and process the robot's start-up and feedback signals.

[0054] When the high-voltage positioning device 200 of this embodiment cooperates with the welding robot to work, in addition to the positive input unit 2031 and the negative input unit 2032 of the high-voltage positioning device 200 being respectively connected to the positive output cable and the negative output cable of the welding machine, and the positive output unit 2033 and the negative output unit 2034 of the high-voltage positioning device 200 being respectively connected to the welding wire and the workpiece of the welding robot through the welding cable, the robot signal interaction unit 202 of the high-voltage positioning device 200 is also connected to the control cabinet of the welding robot through the start and feedback signal line, and the general working process is as follows:

[0055] First, after the welding robot runs to the starting point where welding is required, the welding robot starts the positioning function. When starting, the robot control cabinet outputs a signal to the high-voltage positioning device 200. After the positioning hardware device is started, the connection between the positive input unit 2031 and the negative input unit 2032 of the current input and output unit 203 and the welding machine is disconnected, and the connection with the high-voltage output module 104 of the high-voltage positioning board 100 is connected, and the negative voltage is applied to the workpiece through the welding cable of the negative output unit 2034, and the positive voltage is applied to the welding wire in the welding gun of the welding robot through the welding cable of the positive output unit 2033; then, the welding The robot moves with the welding wire in the welding gun with positive voltage, and contacts the workpiece with negative voltage. At the moment of contact, the high-voltage positioning board 100 will immediately detect the contact signal and immediately output a feedback signal to the welding robot; then, after receiving the detection signal fed back by the high-voltage positioning device 200, the welding robot records the feedback position of the contact; then immediately turns off the signal output to the high-voltage positioning device 200, and the high-voltage positioning device 200 turns off the high-voltage output of the high-voltage output module 104 of the high-voltage positioning board 100, and restores the connection between the welding cable connected to the welding machine and the positive input unit 2031 and the negative input unit 2032. If there are multiple directions of positioning, repeat the above steps. In the above process, when the robot moves, the welding wire will contact the workpiece, and the high-voltage positioning device 200 will immediately give a feedback signal to the robot, and the robot will calculate the position at the time of feedback and compare it with the predetermined trajectory to achieve deviation correction.

[0056] It should be noted that in the above embodiment, the contactor disconnects the welding cable in a manner that can be replaced by using a high-power diode. However, since the high-power diode generates heat and needs to be heat-dissipated, the present invention adopts a high-power contactor to achieve this.

[0057] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
