Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a spot welding parameter dial switch device, system and method. Background Technology
[0002] Spot welding is widely used in automotive body welding production. To meet the welding strength requirements of different sheet metal combinations, appropriate spot welding process parameters must be selected based on parameters such as sheet thickness, material, and number of layers. In production, spot welding pliers equipped with double handles are often used to improve operational flexibility and work efficiency.
[0003] Currently, dual-handle welding clamps use DIP switches to control welding parameters. Each of the two handles has a DIP switch, which is connected in parallel directly to the welding machine's mainboard. However, this parallel structure has a significant drawback: when the operator uses one handle for welding, if the DIP switch on the other handle is not manually adjusted to "0" (i.e., inactive or off), the output signals from both DIP switches will simultaneously act on the mainboard input, causing signal superposition or conflict. This results in the actual output welding parameters deviating from the set values, affecting weld quality and potentially leading to welding defects such as incomplete welds or burn-through. In severe cases, it can even endanger the safety of the vehicle body structure. Summary of the Invention

The method is applied to the spot welding parameter DIP switch device of the first aspect and includes the following steps: selecting a first handle as a control handle, activating a first relay in the circuit of the first DIP switch via a first handle switch of the first handle, inputting a first welding electrical control signal through the first DIP switch, and outputting the first welding electrical control signal through the first relay to control the welding operation; after the welding operation is completed, changing the state of the first handle switch, and the first relay automatically disconnects; switching the control handle to a second handle, activating a second relay in the circuit of the second DIP switch via a second handle switch of the second handle, inputting a second welding electrical control signal through the second DIP switch, and outputting the second welding electrical control signal through the second relay to control the welding operation.

Detailed Implementation
[0018] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0019] The following describes a spot welding parameter DIP switch device, system, and method according to embodiments of this application with reference to the accompanying drawings. Addressing the problem mentioned in the background art where the control signals of the DIP switches on two handles interfere with each other, leading to deviations in welding parameter output, this application provides a spot welding parameter DIP switch device. In this device, a first handle switch, a first DIP switch, and a first relay are arranged in a first handle, and a second handle switch, a second DIP switch, and a second relay are arranged in a second handle. One end of the first DIP switch is connected to the first handle switch, and the other end is connected in series with one end of the first relay, with the other end of the first relay serving as a first output terminal. The second handle includes a second handle switch, a second DIP switch, and a second relay. One end of the second DIP switch is connected to the second handle switch, and the other end is connected in series with one end of the second relay, with the other end of the second relay serving as a second output terminal. This ensures that the welding electrical control signals emitted by the DIP switches on the two handles do not interfere with each other. Therefore, the problem of mutual interference between the control signals of the DIP switches on two handles, leading to deviations in welding parameter output, is solved in the related art.
[0020] Specifically, Figure 1 This is a block diagram of a spot welding parameter DIP switch device provided in an embodiment of this application, as shown below. Figure 1 As shown, the spot welding parameter DIP switch device 10 includes: a first handle 101, a first handle switch 1011, a first DIP switch 1012, a first relay 1013, a second handle 102, a second handle switch 1021, a second DIP switch 1022, and a second relay 1023.
[0021] The first handle 101 and the second handle 102 are switched to control the welding operation. The first handle 101 includes a first handle switch 1011, a first DIP switch 1012, and a first relay 1013. One end of the first handle switch 1011 is connected to the first DIP switch 1012, and the other end of the first handle switch 1011 is connected to the first relay 1013. The other end of the first DIP switch 1012 is connected in series with one end of the first relay 1013. The second handle 102 includes a second handle switch 1021, a second DIP switch 1022, and a second relay 1023. One end of the second handle switch 1021 is connected to the second DIP switch 1022, and the other end of the second handle switch 1021 is connected to the second relay 1023. The other end of the second DIP switch is connected in series with one end of the second relay 1023. The other end of the first relay 1013 and the other end of the second relay 1023 are connected in parallel as an output terminal.
[0022] When the first handle switch 1011 is closed, it supplies power to the first DIP switch 1012 and the first relay 1013.
[0023] It is understood that the first handle 101 and the second handle 102 in this embodiment can be switched to control the welding operation: the first handle 101 includes a first handle switch 1011, a first DIP switch 1012 and a first relay 1013, wherein one end of the first handle switch 1011 is connected to the first DIP switch 1012 and the other end is connected to the first relay 1013, the other end of the first DIP switch 1012 is connected in series with one end of the first relay 1013, and its output signal is output from the other end of the first relay 1013; the second handle 102 includes a second handle switch 1021, a second DIP switch 1022 and a second relay 1023, one end of the second handle switch 1021 is connected to the second DIP switch 1022 and the other end is connected to the second relay 1023, the other end of the second DIP switch 1022 is connected in series with one end of the second relay 1023, and its output signal is output from the other end of the second relay 1023, and the other end of the first relay 1013 and the other end of the second relay 1023 are connected in parallel to form the total output terminal.
[0024] In this embodiment of the application, the first DIP switch 1012 and the second DIP switch 1022 are used to input welding electrical control signals.
[0025] The first DIP switch 1012 and the second DIP switch 1022 are electronic switch components for manually setting digital codes. They are usually composed of multiple single-pole single-throw or single-pole double-throw switches, encapsulated in a housing. Operators can input a set of binary or BCD (Binary-Coded Decimal) codes by toggling the switches of each bit of the first DIP switch 1012 or the second DIP switch 1022. BCD is a way of representing decimal numbers with binary numbers. Its core idea is that each decimal digit (0-9) is represented by a separate set of binary bits. The commonly used one is 8421 code. This code is the welding electrical control signal, used to control the welding system to perform welding operations.
[0026] It is understood that the first DIP switch 1012 and the second DIP switch 1022 in this application embodiment are respectively disposed on the first handle 101 and the second handle 102, and are used to input the corresponding welding electrical control signals. By setting different encoding values, the required welding process parameters are selected, thereby realizing parameterized control of the welding operation.
[0027] In the embodiments of this application, the first relay 1013 and the second relay 1023 are normally open relays.
[0028] Among them, normally open relays can achieve the following: when not energized, their contacts are in an open state and the circuit is not connected; when the coil is energized, the contacts close and the circuit is connected.
[0029] It is understood that the first relay 1013 and the second relay 1023 in this application embodiment are normally open relays, which are used to control the welding electrical control signal output of the first handle 101 and the second handle 102, respectively. By controlling the closing and opening of the first relay 1013 and the second relay 1023, the control handle used in the welding operation can be reliably switched and isolated.
[0030] In this embodiment of the application, the first relay 1013 and the second relay 1023 can be turned on or off according to the preset level control circuit.
[0031] The preset level can be either high or low, depending on the actual needs. No specific limitation is made here. The normally open relay receives high or low level signals through an external drive circuit to control the energization state of the coil, thereby realizing the conduction or disconnection of its contact circuit. In this embodiment, the normally open relay can be made to use either high or low level active based on the corresponding circuit design.
[0032] In this embodiment, the first relay 1013 keeps the circuit of the first DIP switch 1012 disconnected when the first handle switch 1011 is open, and turns on the circuit of the first DIP switch 1012 when the first handle switch 1011 is closed; the second relay 1023 keeps the circuit of the second DIP switch 1022 disconnected when the first handle switch 1011 is open, and turns on the circuit of the second DIP switch 1022 when the second handle switch 1021 is closed.
[0033] It is understood that the first relay 1013 in this embodiment is controlled by the first handle switch 1011: when the first handle switch 1011 is in the open state (not pressed), the coil of the first relay 1013 is de-energized, and its contacts remain open, thereby cutting off the signal circuit of the first DIP switch 1012; when the first handle switch 1011 is pressed (closed), the first relay 1013 is energized and closed, conducting the circuit of the first DIP switch 1012, so that its parameter signal is effectively output; similarly, the second relay 1023 is controlled by the second handle switch 1021: the circuit of the second DIP switch 1022 is conducted only when the second handle switch 1021 is closed (pressed), while the circuit remains open when it is open. This design ensures that only one handle's welding parameter signal is connected to the control system at any given time, avoiding dual-path signal conflict and achieving safe interlocking and accurate parameter switching.
[0034] In this embodiment of the application, the first handle 101 and the second handle 102 are connected in parallel, and the welding electrical control signals output by the first dial switch 1012 and the second dial switch 1022 in the first handle 101 and the second handle 102 do not affect each other.
[0035] It is understood that although the first handle 101 and the second handle 102 in this embodiment are electrically connected in parallel, they achieve independent control of the signal path through their respective integrated first relay 1013 and second relay 1023. Only when a handle is operated will its corresponding relay be activated, connecting the welding control signal output by the handle's DIP switch to the common signal line; the relay of the other unoperated handle remains open, isolating its DIP switch from the system, thereby ensuring that the two welding control signals do not interfere with each other and are independently effective in the parallel structure.
[0036] According to the spot welding parameter DIP switch device proposed in the embodiments of this application, a first handle switch, a first DIP switch and a first relay are set in the first handle, and a second handle switch, a second DIP switch and a second relay are set in the second handle. By connecting one end of the first DIP switch to the first handle switch and the other end in series with one end of the first relay, connecting one end of the second DIP switch to the second handle switch and the other end in series with one end of the second relay, and connecting the other end of the first relay and the other end of the second relay in parallel as the output terminals, it is ensured that the welding electrical control signals emitted by the DIP switches between the two handles do not affect each other.
[0037] Next, the spot welding parameter dial switch system proposed according to the embodiments of this application is described with reference to the accompanying drawings.
[0038] Figure 2 This is a block diagram of a spot welding parameter DIP switch system according to an embodiment of this application.
[0039] like Figure 2 As shown, the spot welding parameter dial switch system 20 includes: at least one of the above-mentioned spot welding parameter dial switch devices 20, at least one welding clamp 201, and a welding machine mainboard 202.
[0040] Each welding clamp 201 corresponds to a spot welding parameter dial switch device 10; one end of the welding machine main board 202 is connected to at least one welding clamp 201, and the other end is connected to the output end of at least one spot welding parameter dial switch device 10 corresponding to the welding clamp 201.
[0041] Among them, welding clamp 201 is a mechanical and electrical tool for performing spot welding operations; welding machine main board 202 is the main control circuit board of welding equipment, which is responsible for receiving welding electrical control signals from spot welding parameter dial switch device 10, parsing them and controlling the corresponding welding clamp to perform welding actions.
[0042] It is understood that the embodiments of this application include at least one spot welding parameter DIP switch device 10, at least one welding clamp 201, and a welding machine main board 202; wherein, each welding clamp 201 is configured with an independent spot welding parameter DIP switch device 10 for setting the welding parameters required for the welding clamp; one end of the welding machine main board 202 is connected to the welding clamp 201 to provide welding power and control commands, and the other end is connected to the output end of the corresponding DIP switch device 10 to receive the welding electrical control signal output by it, thereby realizing accurate identification and automatic switching of welding process parameters of different welding clamps.
[0043] In this embodiment, the welding machine mainboard 202 receives the welding electrical control signal output by the spot welding parameter DIP switch device 10, parses the target welding parameters according to the welding electrical control signal, and controls the corresponding welding clamp 201 to perform welding operations according to the target welding parameters.
[0044] Among them, the welding electrical control signal is a digital coded electrical signal input by the operator through the handle of the spot welding parameter dial switch device 10, which is used to indicate the welding parameter group number to be called; the target welding parameters refer to the specific process data found in the parameter table inside the welding machine main board according to the welding electrical control signal, including welding current, energizing time, electrode pressure, pre-pressure / holding time, etc., which are used to guide the actual welding process.
[0045] It is understood that the welding machine mainboard 202 in this application embodiment receives the welding electrical control signal output from the spot welding parameter DIP switch device 10, and analyzes the signal to determine the corresponding target welding parameters. Then, it generates corresponding control commands based on the target welding parameters to drive the corresponding welding clamp 201 to perform precise welding operations, thereby realizing rapid switching and stable execution of welding processes under different plate combinations.
[0046] In this embodiment of the application, the welding machine motherboard 202 is connected to multiple spot welding parameter DIP switch devices 10 corresponding to the welding clamp 201, including: connecting the output terminals of multiple spot welding parameter DIP switch devices 10 in parallel and then connecting them to the welding machine motherboard 202.
[0047] This refers to connecting the outputs of multiple spot welding parameter DIP switch devices 10 to the same set of common signal lines, and then connecting them to the same input port on the welding machine motherboard.
[0048] It is understood that when the welding machine motherboard 202 of this application embodiment is connected to multiple spot welding parameter DIP switch devices 10, the output terminals of each device are connected in parallel to the same group of common signal lines bit by bit (such as each bit of BCD code), and then uniformly connected to the corresponding input port of the welding machine motherboard 202. This connection method achieves electrical isolation of each signal through relays. The parameter signal of the DIP switch is only connected to the motherboard when the corresponding handle is operated and the relay is energized. This avoids conflicts or misreadings caused by multiple DIP signals acting on the same input terminal at the hardware level, and ensures accurate switching of welding parameters.
[0049] It should be noted that, in the embodiments of this application, when each spot welding parameter DIP switch device 10 is connected to the welding machine motherboard 202, the output of each spot welding parameter DIP switch device 10 is connected to different input terminals of the welding motherboard 202, so that they are independent and do not share the same set of input terminals, thereby enabling parallel processing of two sets of parameters and triggering two welding sequences.
[0050] According to the spot welding parameter dial switch system proposed in the embodiments of this application, the spot welding parameter dial switch device enables the parallel multi-loop control system to accurately control the welding machine motherboard, so that the welding clamp accurately outputs the required welding parameters, and ensures that the control signals between the dial switches do not affect each other, thereby achieving the purpose of precise switching control of welding parameters.
[0051] The spot welding parameter DIP switch system is further described below through a specific embodiment.
[0052] like Figure 3 The diagram shown is a schematic of the spot welding parameter DIP switch system in this embodiment.
[0053] like Figure 3 As shown, this embodiment includes handle switch 1, handle switch 2, handle switch 3, handle switch 4, 8421 DIP switch, normally open relay, welding machine motherboard, welding clamp 1, and welding clamp 2.
[0054] Among them, handle switch 1 and handle switch 2 are connected to the control circuit of welding clamp 1 to control the signal on / off and current output of welding clamp 1; handle switch 3 and handle switch 4 are connected to the control circuit of welding clamp 2 to control the signal on / off and current output of welding clamp 2; the 8421 DIP switch realizes the sequence control of welding parameters through DIP control. When the operator operates the aforementioned handle switch, the electrical signal is transmitted to the corresponding normally open relay via the 8421 DIP switch. Upon receiving the electrical signal, the normally open relay closes, thereby transmitting the electrical signal to the welding machine mainboard. Controlled by the welding machine mainboard, the welding clamp of the corresponding circuit begins to work and outputs current. After the welding operation is completed, the normally open relay opens, a complete work cycle ends, and the control system returns to its pre-operation state.
[0055] Among them, the normally open relay is used to control the circuit on and off in the control system to achieve precise switching of welding parameters. Specifically, the normally open relay is connected in series with the 8421 DIP switch, the welding machine motherboard, and the handle switch in this circuit. The circuit is on and off by switching the switching state of the normally open relay. The circuit on and off can be achieved by either the high level or the low level of the normally open relay.
[0056] It should be noted that in the control system of a one-to-two welding clamp, the normally open relays between different control circuits are connected in parallel. In the control system of this embodiment, the normally open relay only controls the 8421 DIP switch in its own circuit. The signal control of the parallel 8421 DIP switches does not affect each other, and precise control is achieved in their respective circuits. In this embodiment, the welding machine motherboard is connected to the welding clamp system to precisely control the parameter settings and parameter output of the spot welding machine.
[0057] Figure 4 This is a flowchart illustrating the spot welding parameter DIP switch method according to an embodiment of this application.
[0058] like Figure 4 As shown, the spot welding parameter DIP switch method includes the following steps: In step S301, the first handle is selected as the control handle, and the first relay of the circuit where the first DIP switch is located is turned on through the first handle switch. The first welding electrical control signal is input through the first DIP switch, and the first welding electrical control signal is output through the first relay to control the welding operation.
[0059] It is understood that, in this embodiment of the application, when the first handle is selected as the control handle, the first handle switch is operated to turn it on, thereby activating the first relay connected to it, so that the circuit where the first DIP switch is located is energized; at this time, the corresponding first welding electronic control signal is input through the first DIP switch, and the signal is output to the welding machine control system through the contacts of the first relay, so as to perform welding operations according to the selected parameters.
[0060] In step S302, after the welding operation is completed, the state of the first handle switch is changed, and the first relay is automatically disconnected.
[0061] It is understood that, in the embodiments of this application, after the welding operation is completed, when the first handle switch is released, that is, when it returns from closed to open, it cuts off the power supply circuit of the first relay coil, causing the first relay to automatically lose power and disconnect, thereby cutting off the path of the first DIP switch output signal to the welding machine motherboard, ensuring that the handle will not interfere with the system or output invalid parameters when not in operation.
[0062] In step S303, the control handle is switched to the second handle, and the second handle switch of the second handle is used to turn on the second relay in the circuit where the second DIP switch is located. The second welding electrical control signal is input through the second DIP switch and output through the second relay to control the welding operation.
[0063] It is understood that after switching the control handle to the second handle in this embodiment, the second handle switch is closed by operating it, thereby activating the coil circuit of the second relay and causing the second relay to engage. At this time, the circuit where the second DIP switch is located is energized and outputs the second welding control signal according to the settings. This signal is output to the welding machine mainboard through the contacts of the second relay, thereby calling the corresponding welding parameters and controlling the welding clamp to perform welding operations. Through the setting of the relay, efficient switching of welding operation parameters is achieved.
[0064] According to the spot welding parameter DIP switch switching method proposed in the embodiments of this application, by selecting the first handle as the control handle, the first handle switch of the first handle is used to activate the first relay in the circuit where the first DIP switch is located, and the first welding electrical control signal is input through the first DIP switch. The first welding electrical control signal is output through the first relay to control the welding operation. After the welding operation is completed, the state of the first handle switch is changed, and the first relay is automatically disconnected. The control handle is then switched to the second handle, and the second handle switch of the second handle is used to activate the second relay in the circuit where the second DIP switch is located. The second DIP switch is used to input the second welding electrical control signal, and the second welding electrical control signal is output through the second relay to control the welding operation. This ensures that the welding electrical control signals issued by the DIP switches between the two handles do not interfere with each other, and achieves efficient switching of welding operation parameters.
