Description

Technical Field

[0001] The invention relates to the technical field of welding equipment control, in particular to a method for multi-standard output and monitoring of a manual resistance welding controller. Background Art

[0002] Manual resistance welding controllers have been widely used in the field of automobile manufacturing, especially in the welding process of white body, and have become indispensable equipment due to their flexibility and efficiency. However, with the continuous launch of new models, the pilot workshop of automobile factories has put forward higher requirements on the functions of welding controllers. The traditional manual resistance welding controllers currently used usually can only support limited welding specifications, and usually one device can only be configured with two welding specifications. This limitation leads to the need to frequently replace equipment when responding to different welding needs, which increases the complexity and time cost of operation, and is difficult to adapt to the needs of the pilot workshop for diversified welding specifications.

[0003] In addition, existing welding controllers usually lack real-time monitoring functions, and parameter changes during the welding process cannot be fed back to the operator in a timely manner. This lack of monitoring design makes it difficult for the operator to intuitively understand the current welding status, and the stability of the welding quality is also difficult to guarantee. Once a parameter abnormality or operating error occurs, it is impossible to take timely measures to correct it, which may lead to substandard welding quality, increase the scrap rate, and affect the overall progress and cost control of the trial production. Therefore, the existing manual resistance welding controllers are insufficient in terms of the diversity of standard outputs and real-time monitoring capabilities, and it is difficult to effectively meet the high standards for welding equipment in the trial production stage of new models.

[0042] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a method for multi-standard output and monitoring of a manual resistance welding controller, which aims to meet the diversified needs of new car model trial production workshops in the field of automobile manufacturing for manual resistance welding. Through multi-standard output and real-time monitoring, the flexibility and reliability of the welding process are improved, and the trial production cost of new car models is reduced. The specific implementation methods of the present invention are described in detail below.

[0044] like Figure 2 and Figure 2 As shown, this method relies on the system structure of the manual resistance welding controller, including multiple welding clamp handle dip switches, 16-way switch detection module, communication adapter board, controller main control board, digital tube display module and welding start switch. The functions and connection methods of each module are as follows:

[0045] Welding clamp handle dip switch: used to select welding specifications, including 1# welding clamp 1# handle dip switch (-1S1), 1# welding clamp 2# handle dip switch (-1S2), 2# welding clamp 1# handle dip switch (-2S1), 2# welding clamp 2# handle dip switch (-2S2).

[0046] 16-way switch detection module (-ZY): used to receive welding specification signals from multiple welding clamp handle dip switches and convert the signals into digital signals for transmission.

[0047] Communication adapter board (-ZP): used to receive welding specification signals from the 16-way switch detection module, and communicate with the controller main control board through RS485 communication. It is also responsible for transmitting the signal of the controller main control board to the digital tube display module.

[0048] Controller main control board (-C1): As the core module of the controller, the main control board receives welding specification signals and welding start signals, and performs corresponding welding operations according to the set welding specifications.

[0051] The connections and signal flows between the modules of the system are as follows:

[0052] 1. Connection between the welding clamp handle dip switch and the 16-way switch detection module

[0053] The DIP switch on the welding clamp handle outputs welding specification signals through 8421 coding. Specifically:

[0054] The connection points 1, 2, 4, and 8 of -1S1 are respectively connected to the connection points IN1, IN2, IN3, and IN4 of the 16-way switch detection module (-ZY).

[0055] The connection points 1, 2, 4, and 8 of -1S2 are connected to the connection points I N5, I N6, I N7, and I N8 of -ZY respectively.

[0056] The connection points 1, 2, 4, and 8 of -2S1 are connected to the connection points I N9, I N10, I N11, and I N12 of -ZY respectively.

[0057] The connection points 1, 2, 4, and 8 of -2S2 are connected to the connection points IN13, IN14, IN15, and IN16 of -ZY respectively.

[0058] The above connection ensures that the 8421 coding signal of each dip switch can be identified and processed by the -ZY module. At the same time, the C point of all dip switches is short-circuited and connected to the 24V positive power supply to ensure the stable transmission of the coding signal.

[0059] 2.16-way switch detection module and communication adapter board connection

[0060] After receiving the welding specification signals from the dip switches, the 16-way switch detection module (-ZY) converts these signals into digital signals and transmits them to the communication adapter board (-ZP) via RS485 communication.

[0061] The specific connections are as follows:

[0062] The power supply V+ terminal of -ZY is connected to the positive pole of the P4 terminal of -ZP, and the GND terminal is connected to the negative pole of the P4 terminal to ensure the stability of power supply.

[0063] In the RS485 interface of -ZY, the A / D+ port is connected to the P4 interface A of -ZP, and the B / D- port is connected to the P4 interface B of -ZP, forming an RS485 communication connection. This connection method ensures the anti-interference of signal transmission and is suitable for use in industrial environments.

[0064] 3. Connection between the communication adapter board, digital tube display module and controller main control board

[0065] In addition to receiving welding specification signals, the communication adapter board (-ZP) is also connected to the digital tube display module and the controller main control board, as follows:

[0066] -The positive and negative poles of the ZP power interface are connected to the 24V positive power supply and 0V negative power supply respectively to ensure power supply.

[0067] The positive and negative poles of the P5 interface of -ZP are respectively connected to the positive and negative poles of the power supply of the digital tube display module (-ZS), the A end of the P5 interface is connected to the A / TX interface of -ZS, and the B end is connected to the B / RX interface of -ZS to ensure that the welding specification information can be displayed on the digital tube in real time.

[0068] The P1 interface of -ZP is connected to the X8 interface of the controller main control board (-C1) through RS485 communication to ensure that the welding specification signal can be smoothly transmitted to the controller main control board.

[0069] 4. Connection between welding start switch and controller main control board

[0070] Each welding clamp handle is equipped with a welding start switch (-1H1, -1H2, -2H1, -2H2) to start the welding operation. The specific connections are as follows:

[0071] Port 14 of -1H1 is connected to IO1 port of the controller main control board, port 14 of -1H2 is connected to IO2, port 14 of -2H1 is connected to IO3, and port 14 of -2H2 is connected to IO4.

[0072] The No. 13 port of each welding start switch is short-circuited and connected to the COM port of the controller main control board to form a common ground for the start switch.

[0073] like Figure 1 As shown, the present invention provides a method for multi-specification output and monitoring of a manual resistance welding controller. The method aims to achieve the selection, execution and real-time monitoring of multiple welding specifications through a controller, thereby meeting the needs of different welding conditions and improving welding quality, and is particularly suitable for the manual welding process of white body in automobile manufacturing.

[0074] The method of the present invention selects welding specifications through multiple welding clamp handle dial switches, transmits welding specification signals to the controller main control board through a 16-way switch quantity detection module, and then controls the welding operation in combination with a welding start signal. At the same time, the controller main control board transmits the welding specification information to the digital tube display module through a communication adapter board to realize real-time display of the welding specifications. The method enables a welding controller to support multiple welding specifications and monitor the current welding status in real time to ensure the accuracy and stability of the welding process.

[0075] The specific implementation steps of the method of the present invention are as follows:

[0076] Step 1: Welding Specification Selection

[0077] The operator selects the welding specification through the dip switch on the welding clamp handle. Each dip switch outputs the welding specification signal in 8421 coding mode. For example, different dip switch combinations (such as 1# welding clamp 1# handle dip switch-1S1, 1# welding clamp 2# handle dip switch-1S2, etc.) can represent different welding specifications.

[0078] 8421 coding mode: Each DIP switch outputs 8421 coding signals through the combined wiring points (such as wiring points 1, 2, 4, and 8). 8421 coding is a binary weighted coding that can be combined to form 16 different signals, thereby supporting up to 16 welding specifications. Different coding signal combinations can represent different process parameter settings such as welding current and voltage.

[0079] Operation process: The operator selects the welding specification by turning the DIP switch. For example, when a specific welding specification is selected, the 8421 coding signal of the DIP switch will be output from each wiring point and transmitted to the 16-way switch detection module.

[0080] Step 2: Detection and transmission of welding specification signals

[0081] The welding specification signal is transmitted to the 16-way switch quantity detection module through the wiring points of each dip switch, and the input end (IN1 to IN16) of the module is respectively connected to different dip switch signal input points.

[0082] Signal detection: The 16-way switch detection module receives the 8421 coded signal and converts it into the corresponding welding specification data. The function of this module is to convert the physical switch signal (i.e. coded signal) into a digital signal for subsequent data processing and communication.

[0083] Signal transmission: The 16-channel switch detection module transmits the digital welding specification signal to the communication adapter board via RS485 communication. RS485 is a commonly used industrial communication standard with good anti-interference ability, suitable for signal transmission in industrial environments, ensuring that the welding specification signal can be transmitted stably.

[0084] Step 3: Communication adapter board signal processing and transmission

[0085] After the communication adapter board receives the welding specification signal from the 16-way switch detection module, it acts as a signal transfer station and transmits the welding specification signal to the controller main control board through RS485 communication.

[0086] Signal transfer: After the communication adapter board receives the welding specification signal, it converts the signal into a standard data format that can be received by the main control board through the internal communication protocol, and sends it to the controller main control board.

[0087] Signal synchronous transmission: In addition to transmitting to the controller main control board, the communication adapter board is also responsible for sending the welding specification information to the digital tube display module to display the welding specification status in real time, so that the operator can intuitively understand the current welding status.

[0088] Step 4: The controller main board sets the welding specifications and waits for the start signal

[0089] After receiving the welding specification signal transmitted by the communication adapter board, the controller main control board analyzes the welding specification and prepares the corresponding welding output conditions (such as welding current and voltage) according to the set parameters. This step enables the controller main control board to load the welding specification settings in advance and prepare for the start of welding.

[0090] Parameter setting: According to the welding specification signal, the main control board loads the corresponding welding current, voltage, pulse time and other process parameters. For example, for the welding of high-strength steel, the main control board can set a higher welding current; while for the welding of thin plates or aluminum alloys, a relatively low welding current will be set to avoid welding burn-through or poor quality.

[0091] Ready state: After receiving the welding specification signal, the controller main control board enters the ready state and waits for the input of the welding start signal.

[0092] Step 5: Receive welding start signal and perform welding operation

[0093] When the operator presses the welding start switch (such as -1H1, -1H2, etc.) on the welding clamp handle, the start signal is transmitted to the designated port (such as IO1 to IO4) of the controller main control board through a dedicated signal line.

[0094] Start signal recognition: After the controller main control board receives the welding start signal, it confirms that the operator has selected a specific welding clamp and welding specification. The system will once again confirm whether the welding specification signal is correct before starting welding.

[0095] Welding execution: After the welding start signal and welding specification signal are confirmed to be correct, the controller main control board starts to execute the welding operation. According to the loaded parameter settings, the main control board controls the output of the welding current and performs welding according to the preset welding current, voltage and time parameters to ensure the quality stability of the welding process.

[0096] Step 6: Real-time display of welding specification status

[0097] During the welding operation, the controller main control board will transmit the current welding specification information to the digital tube display module through the communication adapter board, and display the current welding specification status in real time.

[0098] Specification display: The digital tube display module can intuitively display information such as welding specification number, welding status (in progress, completed or abnormal). This display function ensures that the operator can understand the specification status of the welding process at any time, which is convenient for real-time monitoring of the welding process.

[0099] Abnormal reminder: If an abnormality occurs during the welding process, such as the current is too large or too small, the main control board will transmit an alarm message to the digital tube display module through the communication adapter board to remind the operator to take immediate measures.

[0100] In general, the present invention selects welding specifications through the dip switch on the welding clamp handle, uses 8421 coding to transmit signals, transmits welding specification signals to the controller main control board for setting through the 16-way switch detection module and the communication adapter board, and performs welding operations after receiving the welding start signal. At the same time, the controller main control board transmits welding specification information to the digital tube display module in real time through the communication adapter board to realize real-time monitoring of the specifications. The method supports up to 16 welding specification outputs, adapts to different welding requirements, improves the flexibility and stability of the welding process, and is particularly suitable for trial production of new models in the field of automobile manufacturing.
