[0002] TIG welding as a kind of precision welding is widely used in welding field, there are manual welding, semi-automatic welding and automatic welding. In the welding process, in addition to welding, welder will also carry out the operation of workpiece, tooling fixture or other non-welding operation. When multiple stations have such operation, the maximum number of stations at the same time is less than the total number of stations, there is no welding power supply used at each time. In the prior art, the user mostly adopts the scheme of one power supply for each station, which causes waste of equipment resources. SUMMARY

[0003] The purpose of the present application is to provide a welding equipment automatic distribution method, system, medium and equipment, through the automatic distribution system, the welding station needs to connect the corresponding welding gun to the welding equipment, and the equipment does not need to be welded. Not only meet the needs of station welding, but also reduce the investment of users to the equipment, improve the utilization rate of welding machine equipment.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme.

[0005] In the first aspect, the present application provides a welding equipment automatic distribution method, a main controller is connected with an input unit, a power distribution controller, an output unit, a communication unit and a gas valve controller, the method is executed by the main controller, comprising:

[0006] In response to receiving the station closing signal sent by the input unit, the station number corresponding to the station closing signal and the called channel number are extracted;

[0007] The connection state of each welding power supply is searched in order, when an unused welding power supply is searched, the power supply serial number of the welding power supply and the station number are sent to the power distribution controller, which is used to electrically connect the searched welding power supply with the welding station corresponding to the station number;

[0008] The called channel number is forwarded to the welding power supply through the communication unit;

[0009] The station number is sent to the gas valve controller, which is used to open the gas valve of the corresponding welding station;

[0010] The station number is sent to the output unit, which is used to start the corresponding welding power supply;

[0011] In response to receiving the welding end signal sent by the welding power supply, the welding end process is executed.

[0012] Further, the input unit receives the station start switch signal and the called channel parameter sent by the welding station unit, and the welding station unit is provided with N welding stations for performing actual welding operation.

[0013] Further, the output unit sends the station number corresponding to the station closing signal to the welding equipment unit, the welding equipment unit is provided with M welding power sources for controlling the start welding switch of the welding power source, and N>M.

[0014] The present application adopts the setting that the number of stations N is greater than the number of welding power sources M, and by sharing the power source by the welding station, it is ensured that the welding demand is met, compared with the traditional fixed matching mode, the present application method effectively reduces the configuration number of the power equipment, reduces the user investment, and improves the equipment utilization.

[0015] Further, each station needs to store the welding process parameters to the process group corresponding to the welding power source, and each station stores the channel parameters used in the channel group on the welding power source before welding, and the channel parameters are copied to the same channel of other welding power sources in a communication manner;

[0016] The input unit of the automatic distribution controller receives the welding gun switch signal and the called channel parameter of the station in real time, when the input unit detects that the station without welding has a start signal input, the input unit sends the station number and the called channel number to the main controller, the main controller queries the connection state of the welding power source in the order from small to large, when detecting the unused welding power source, the main controller controls the power distribution controller, so that the station is electrically connected with the power source, and the welding power source is informed of the channel number to be called through the communication unit, and the gas valve controller controls the gas valve of the corresponding station to be connected, and then the output start signal is outputted to make the welding power source output;

[0017] The welding power source informs the main controller of the working state in a communication manner, when the welding power source ends welding (hysteresis stop gas ends), the main controller is also informed in a communication manner;

[0018] After the main controller receives the welding end message, the gas valve control unit is controlled to close the corresponding gas valve, and the electrical connection between the power source and the welding gun in the power distribution controller is not synchronously disconnected, and a waiting extension time is waited, if there is no start input signal, the electrical connection between the power source and the welding gun in the power distribution controller is disconnected, and the welding machine is in an unused state.

[0019] In the present application, the welding power source is informed of the welding process parameters of the corresponding station by the automatic distribution controller in a communication manner, which ensures the normal welding of the welding station and avoids the connection error problem, and improves the efficiency.

[0020] Further, the welding end process comprises:

[0021] When the main controller receives the welding end signal sent by the welding power supply and the welding power supply corresponding station start signal is disconnected, the gas valve corresponding to the welding power supply is closed by the gas valve controller, but the electrical connection between the welding power supply and the welding torch in the power distribution controller is maintained;

[0022] If there is no start input signal before the extended waiting time after the welding power supply welding ends, the power distribution controller is controlled to disconnect the electrical connection between the welding power supply and the welding torch.

[0023] Further, the extended waiting time is set to a first time threshold , The value is set according to the actual situation.

[0024] Further, the process of the input unit sending the station closing signal is:

[0025] Determine the number of stations;

[0026] When the input unit finds that the station start switch is closed, the station number and the channel number called by the station are sent to the welding power supply for subsequent operation;

[0027] When the station start switch is not found to be closed, the next station is scanned:

[0028] When the detected number of stations is greater than the maximum value, the number of stations is re-determined;

[0029] When the detected number of stations is less than the maximum value, it is detected whether the station start switch is closed.

[0030] Further, the subsequent operation of the welding power supply comprises:

[0031] When the station number and the channel number sent by the communication unit are received, the channel is called;

[0032] When the control end receives the change of the control signal, the corresponding current is output according to the control logic and timing;

[0033] When the power welding ends and the hysteresis gas stop ends, the automatic distribution controller is informed by the communication unit that the power welding ends.

[0034] Further, the welding end signal cannot be directly determined by the station control signal, because of the existence of the arc collection and the spot welding situation: in the arc collection state, even if the start switch is disconnected, the welding process may continue; while in the spot welding process, even if the start switch is closed, the welding may stop, so the welding end signal cannot be determined by the start switch, and the welding power supply needs to send the welding end signal;

[0035] On this basis, the method introduces a waiting time extension, when the waiting time is within an extension threshold, the system will maintain the original welding power distribution state, avoiding frequent switching of the power supply caused by short-time repeated welding; when the waiting time exceeds the extension threshold, it can be considered that the station will not be welded again in a short time, and other operations are performed.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0059] Example 1

[0060] like Figure 1 As shown in the figure, this embodiment introduces an automatic power distribution method for welding equipment. The main controller is connected to the input unit, power distribution controller, output unit, communication unit, and gas valve controller. The method is executed by the main controller and includes:

[0061] In response to receiving a station closure signal from the input unit, the station number and the channel number called corresponding to the station closure signal are extracted;

[0062] The connection status of each welding power source is searched sequentially. When an unused welding power source is found, its power source serial number and the station number are sent to the power distribution controller to electrically connect the found welding power source to the welding station corresponding to the station number.

[0063] The channel number called is forwarded to the welding power source via the communication unit;

[0064] The workstation number is sent to the gas valve controller to open the gas valve of the corresponding welding workstation;

[0065] The workstation number is sent to the output unit to start the corresponding welding power supply;

[0066] In response to receiving a welding end signal from the welding power source, the welding end procedure is executed.

[0067] Furthermore, the input unit receives the station start switch signal and the channel parameters called by the welding station unit. The welding station unit has N welding stations for performing actual welding operations.

[0068] Furthermore, the output unit sends the station number corresponding to the station closure signal to the welding equipment unit. The welding equipment unit is equipped with M welding power supplies to control the start welding switch of the welding power supply, and N>M.

[0069] Furthermore, each station needs to store the welding process parameters in the process group corresponding to the welding power source. In this implementation, each station is allocated 10 channels, so channels 1-10 are allocated to station 1, channels 11-20 are allocated to station 2, channels 21-30 are allocated to station 3, and so on. Before welding, each station stores the channel parameters used in the channel group on the welding power source, and the channel parameters will be copied to the same channels of other welding power sources in a communication manner.

[0070] Furthermore, such as Figure 2 and Figure 3 As shown, the main controller determines whether it has received the workstation data sent by the input unit. ( The station closure signal condition (for any station) is:

[0071] When the workstation is received When the closing signal is received, the welding power supply connection status is searched in ascending order, and an idle power supply number is detected. Control the power distribution controller to connect the idle power output terminal to the workstation. The welding torch is electrically connected; it communicates with the power supply via a communication unit, transmitting the workstation number. Channel for workstation access Send to power supply The workstation is controlled by the air valve controller. The air valve is opened; the closed signal status of the workstation is sent to the power supply via the communication unit. The control terminal;

[0072] The above operation is not performed if no closing signal is received.

[0073] Furthermore, the welding completion process includes:

[0074] The main controller receives welding power. ( The welding end signal is sent to any power source and the welding power source. When the corresponding workstation start signal is disconnected, the gas valve controller controls the welding power supply. The corresponding gas valve is closed, but the welding power is maintained in the power distribution controller. Electrical connection with the welding torch;

[0075] If the welding power source Extended waiting time after welding If no start input signal is received before the end, the power distribution controller will disconnect the welding power supply. Electrical connection with the welding torch.

[0076] Furthermore, when the workstation ( When the state of the welding torch (for any station) changes, the station... The status of the welding torch is sent to the control terminal of the corresponding welding power source through the output unit.

[0077] Furthermore, the extended waiting time is set as the first time threshold. In this embodiment, a first time threshold is set. It lasts for 20 seconds.

[0078] Furthermore, such as Figure 4 As shown, the process of the input unit sending the station closure signal is as follows:

[0079] Determine the number of workstations ;

[0080] When the workstation start switch is detected to be closed, the closed workstation number will be... and the channel number called by this workstation Send to the power source for further processing;

[0081] The number of workstations increases when no workstation start switch is detected to be closed. Begin scanning at the next workstation:

[0082] When the number of workstations detected Greater than the maximum value At that time, reassess the number of workstations;

[0083] When the number of workstations detected Less than the maximum value At that time, check whether the start switch of the detection station is closed.

[0084] Furthermore, such as Figure 5 As shown, the power supply performs subsequent operations including determining the workstation number received from the communication unit. and channel number At that time, according to the formula Perform a channel call, where, The number of channels allocated to each workstation;

[0085] When the control terminal receives a change in the control signal, it outputs the corresponding current according to the control logic and timing.

[0086] When the power welding ends and the delayed gas supply ends, the automatic distribution controller is notified via the communication unit that the power welding has ended.

[0087] In this embodiment, the welding end signal cannot be directly determined by the station control signal because of the existence of arc extinguishing and spot welding: in the arc extinguishing state, the welding process may continue even if the start switch is turned off; while in the spot welding process, the welding may stop even if the start switch is closed. Therefore, the welding end signal cannot be determined by the start switch and the welding power supply needs to send a welding end signal.

[0088] Based on this, this embodiment introduces an extended waiting time. When the waiting time is within the extended threshold, the system will maintain the original power supply allocation state to avoid frequent power switching caused by short-term repeated welding. When the waiting time exceeds the extended threshold, it can be assumed that the station will not weld again in a short time and will be performing other operations.

[0092] The dynamic allocation module is used to sequentially retrieve the connection status of each welding power source. When an unused welding power source is retrieved, the power source serial number and the station number of the welding power source are sent to the power allocation controller to electrically connect the retrieved welding power source with the welding station corresponding to the station number.

[0093] The channel forwarding module is used to forward the invoked channel number to the welding power source through the communication unit;

[0094] The air valve control module is used to send the workstation number to the air valve controller to open the air valve of the corresponding welding workstation.
