Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a welding equipment control method and a welding equipment control system. Background Art

[0002] When using existing welding equipment, all welding parameters need to be manually set by the welding operator based on his own experience or the recommended parameters in the welding parameter table in the welding machine user manual. Once the welding operator is inexperienced and the welding machine user manual is lost, the welding operator will not know how to set the parameters. Without the correct welding parameters, normal welding operations cannot be performed. Once this happens, it will make it difficult for welding work to proceed normally and greatly affect the user experience. In response to this situation, some welding equipment also provides corresponding solutions, such as affixing stickers with recommended welding parameters on the outer shell of the welding equipment, or adding a QR code to the outer shell of the welding equipment. Scanning the QR code can obtain welding parameters and welding operation videos. These solutions can solve the above problems to a certain extent, but they cannot solve them perfectly. When using welding equipment, operators still need to spend a lot of time to query welding parameters, and there are cases where manual input is incorrect, which affects welding efficiency and welding quality.

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present application will be comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted. "Or" and "or" in the specification may both mean "and" or "or". Although "first" or "second" etc. are used in this specification to represent certain features, they are only used to represent the function and are not used as a limitation on the number and importance of specific features.

[0041] The welding equipment in the prior art requires operators to manually input welding parameters, which places high demands on operators, has low welding efficiency, and may affect welding quality due to incorrect input welding parameters. Based on this, the present application provides a welding equipment control method, which automatically identifies the diameter of the welding rod, automatically queries the welding parameters according to the diameter of the welding rod, and automatically controls the welding process based on the queried welding parameters, thereby improving welding efficiency, ensuring the accuracy of welding parameter settings, improving welding quality, and reducing the ability requirements for operators.

[0042] like Figure 1 As shown, the embodiment of the present application provides a welding equipment control method, comprising the following steps:

[0043] S100: collecting the diameter of the welding rod currently clamped by the welding equipment;

[0044] In this embodiment, a sensor is provided on the welding clamp of the welding equipment, and when the welding clamp clamps welding rods of different diameters, the diameter of the currently clamped welding rod can be accurately measured by the sensor;

[0045] S200: Determine the welding parameter corresponding to the diameter of the current clamped welding rod based on the preset correspondence between the welding rod diameter and the welding parameter;

[0046] The correspondence between the electrode diameter and the welding parameters is pre-stored in a welding equipment control system. For example, the control system includes an MCU (microcontroller unit) which is disposed in a housing of the welding equipment. The correspondence between the electrode diameter and the optimal welding parameters corresponding thereto is pre-stored in the MCU.

[0047] In this embodiment, the welding parameters include welding current; in the preset correspondence between the electrode diameter and the welding parameters, since a larger diameter electrode will require more heat to melt, the larger the electrode diameter, the larger the welding current is to ensure normal melting of the electrode and a stable welding process; for example, for a 2.5 mm electrode, the welding current is generally between 60-90 A, and for a 4.0 mm diameter electrode, the welding current is generally between 160-210 A; the values ​​of the electrode diameter and the welding current are only examples, and in actual applications, the specific value of the welding current in the pre-stored correspondence can be set according to specific circumstances;

[0048] The specific implementation of the welding equipment control method is described below by taking the welding parameters including the welding current as an example. In other embodiments, the welding parameters may also include other types of parameters, such as welding voltage, welding speed, etc.;

[0049] S300: Controlling a welding process of a welding device based on the determined welding parameters.

[0050] By adopting the welding equipment control method of the present application, firstly, step S100 is used to automatically identify the diameter of the welding rod currently clamped by the welding equipment, and then step S200 is used to automatically query the optimal welding parameters corresponding to the currently clamped welding rod based on the preset correspondence between the welding rod diameter and the welding parameters, and step S300 is used to control the welding process of the welding equipment based on the welding parameters determined in step S200, thereby realizing intelligent automation of welding parameter setting, without the need for manual input by the operator, reducing the ability requirements for the operator, and even inexperienced operators can correctly use the welding equipment, reducing the time and energy of the operator to manually input the welding parameters, improving the welding efficiency, and greatly improving the user experience. The welding parameters are automatically obtained according to the automatically identified welding rod diameter, the welding parameters are accurate, and the situation of manual input errors is avoided, which effectively guarantees the welding quality.

[0051] In this embodiment, the step S100: collecting the diameter of the welding rod currently clamped by the welding equipment, includes the following steps:

[0052] Collect the displacement of the electrode clamping device of the welding equipment when clamping the electrode;

[0053] In this embodiment, the electrode clamping device and the welding clamp are devices used to clamp the electrode in the welding equipment, and the devices are used to clamp the electrode and connect with the output circuit of the welding equipment to form a current circuit; the displacement of the electrode clamping device when clamping the electrode is the opening angle of the electrode clamping device when clamping the electrode; the sensor provided in the electrode clamping device is, for example, an angle sensor;

[0054] The diameter of the welding rod currently clamped by the welding equipment is determined according to the displacement; specifically, the method includes collecting the opening angle of the welding rod clamping device of the welding equipment when clamping the welding rod from an angle sensor arranged on the welding rod clamping device.

[0055] The angle sensor is, for example, an inductive angle sensor, a capacitive angle sensor, an optical angle sensor, etc., which is arranged on the clamping arm of the electrode clamping device. When the electrode clamping device clamps the electrode, the opening angle of the electrode clamping device can be collected through the angle sensor.

[0056] After measuring the opening angle of the electrode clamping device when clamping the electrode, in one embodiment, the diameter of the currently clamped electrode can be calculated by the relationship between the opening angle and the electrode diameter. For example, the distance between the first end (the end that clamps the electrode) and the second end (the end close to the output end of the electric welding equipment) of the clamping arm of the electrode clamping device is s, and the measured opening angle is a, then the diameter of the electrode is d=2*sin(a / 2). In another embodiment, the opening angle of the electrode clamping device when the electrode clamping device clamps electrodes of different diameters can be pre-stored, and the corresponding data of the electrode diameter and the opening angle are stored as a mapping table. After measuring the current opening angle of the electrode clamping device, a pre-stored opening angle closest to the current opening angle is searched in the mapping table, and the electrode diameter corresponding to the pre-stored opening angle is the diameter of the currently clamped electrode.

[0057] In this embodiment, the correspondence between the preset electrode diameter and the welding parameter is a preset mapping table of electrode diameter and welding parameter. Since the commonly used electrode diameters on the market have several fixed specifications and sizes, the corresponding welding parameters of these specifications and sizes are set in advance to form a mapping table of electrode diameter and welding parameters, which can basically meet the welding requirements in the current scenarios of using various electrode diameters.

[0058] In another embodiment, the correspondence between the preset electrode diameter and the welding parameter can also be a functional relationship, y=f(x), y represents the value of the welding parameter, x represents the electrode diameter, and f(x) can be a linear function or a nonlinear function. A functional relationship between welding parameters and electrode diameters is pre-constructed, and a plurality of welding parameters corresponding to electrode diameters are pre-set to form a pre-set data pair. The plurality of data pairs are substituted into the functional relationship, and the coefficients in the functional relationship can be obtained, thereby establishing a functional relationship between electrode diameter and welding parameters.

[0059] In this embodiment, before the step S300: controlling the welding process of the welding equipment based on the determined welding parameters, the following steps are also included:

[0060] Displaying the determined welding parameters on a parameter display module of the welding device; the parameter display module is, for example, a display screen disposed on a housing of the welding device, and displays the welding parameters determined in step S200, and an operator can view the parameters through the parameter display module;

[0061] Determining whether updated welding parameters input by the user are received;

[0062] After checking the determined welding parameters through the parameter display module, the operator can default to using the determined welding parameters for subsequent welding. If the determined welding parameters are considered inappropriate, the operator can also modify the welding parameters through the parameter adjustment module; the parameter adjustment module can be integrated with the parameter display module into a touch screen, and the operator can input the modified welding parameters through the touch screen; or the parameter adjustment module can also be in the form of an input module such as a key, button, knob, keyboard, etc.

[0063] If yes, controlling the welding process of the welding device based on the updated welding parameters input by the user;

[0064] Specifically, the updated welding parameters are sent to the welding current control circuit of the welding equipment control system, and the welding current control circuit controls the output current of the welding equipment based on the updated welding parameters; and after the user updates the welding parameters, the parameter display module can display the welding parameters updated by the user;

[0065] If not, the welding process of the welding equipment is controlled based on the welding parameters determined in step S200;

[0066] Specifically, the welding parameters determined in step S200 are sent to the welding current control circuit of the welding equipment control system, and the welding current control circuit controls the output current of the welding equipment based on the determined welding parameters.

[0067] Therefore, in the welding equipment control method of this embodiment, not only the automatic setting of welding parameters is realized, but also when the operator is not satisfied with the automatically set welding parameters, the welding parameters can be manually adjusted to achieve the purpose of personalized setting, so that the welding operation of the welding equipment can better meet the operational requirements.

[0068] In this embodiment, after controlling the welding process of the welding equipment based on the updated welding parameters, the following steps are also included:

[0069] The correspondence between the preset electrode diameter and the welding parameters is updated based on the diameter of the electrode currently clamped by the welding equipment and the updated welding parameters.

[0070] Therefore, in the welding equipment control method of this embodiment, after the operator readjusts the welding parameters, the preset correspondence between the electrode diameter and the welding parameters stored in the MCU can also be updated according to the operator's welding parameters. For example, in the previously preset correspondence between the electrode diameter and the welding parameters, corresponding to the electrode with a diameter of 2.5 mm, the welding current is set to 80A. After the electrode clamping device clamps the electrode with a diameter of 2.5 mm, the displacement of the electrode clamping device is collected through step S100, and the diameter of the current clamped electrode is determined to be 2.5 mm according to the displacement. The electrode with a diameter of 2.5 mm corresponds to a welding current of 80A, and then the welding current of 80A is displayed in the parameter display module. After the operator sees that the welding current is 80A through the parameter display module, if no modification is made, the subsequent welding process will use a welding current of 80A. If the operator thinks that 80A is not suitable and should be changed to 85A, the new welding current 85A can be input through the parameter adjustment module, and the subsequent welding process will use a welding current of 85A. At the same time, the welding current corresponding to the electrode with a diameter of 2.5 mm stored in the MCU is updated to 85 A. When the electrode clamping device clamps the electrode with a diameter of 2.5 mm again, the welding current obtained by querying in step S200 is 85 A. Therefore, by recording and updating the adjustment feedback of the operator, the correspondence between the electrode diameter and the welding parameters stored in advance can be further optimized to avoid repeated adjustments by the operator.

[0071] like Figure 2 As shown, the embodiment of the present application also provides a welding equipment control system, including:

[0072] The data acquisition module M100 is used to collect the diameter of the welding rod currently clamped by the welding equipment;

[0073] The parameter query module M200 is used to determine the welding parameter corresponding to the diameter of the current clamped welding rod based on the preset correspondence between the welding rod diameter and the welding parameter;

[0074] The welding control module M300 is used to control the welding process of the welding equipment based on the determined welding parameters.

[0075] By adopting the welding equipment control system of the present application, the diameter of the welding rod currently clamped by the welding equipment is automatically identified through the data acquisition module M100, and then the optimal welding parameters corresponding to the currently clamped welding rod are automatically queried through the parameter query module M200 based on the preset correspondence between the welding rod diameter and the welding parameters, and the welding process of the welding equipment is controlled through the welding control module M300 based on the welding parameters determined in the parameter query module M200, thereby realizing intelligent automation of welding parameter setting, without the need for manual input by the operator, reducing the ability requirements for the operator, and even inexperienced operators can use the welding equipment correctly, reducing the time and energy of the operator to manually input the welding parameters, improving the welding efficiency, and greatly improving the user experience. The welding parameters are automatically obtained according to the automatically identified welding rod diameter, the welding parameters are accurate, and the situation of manual input errors is avoided, effectively ensuring the welding quality.

[0076] like Figure 3 As shown, in this embodiment, the data acquisition module M100 includes:

[0077] The displacement detection unit M110 is used to collect the displacement detection signal of the electrode clamping device of the welding equipment when clamping the electrode; the displacement detection unit M110 is, for example, an angle sensor;

[0078] The displacement conversion unit M120 is used to convert the displacement detection signal into an electrical signal corresponding to the welding rod diameter; the displacement conversion unit M120 collects the opening angle signal collected by the angle sensor from the angle sensor, and determines the welding rod diameter based on the correspondence between the opening angle and the welding rod diameter for subsequent processing by the parameter query module M200. The displacement conversion unit M120 outputs a digital electrical signal representing the size of the welding rod diameter to the parameter query module M200.

[0079] like Figure 3 As shown, in this embodiment, the welding equipment control system also includes:

[0080] The parameter display module M400 is used to display the welding parameters determined by the parameter query module M200;

[0081] The parameter adjustment module M500 is used to receive updated welding parameters input by the user;

[0082] The welding control module M300 is configured to determine whether the parameter adjustment module M500 receives the updated welding parameters input by the user. If so, the welding process of the welding equipment is controlled based on the updated welding parameters input by the user, and the updated welding parameters are sent to the specific welding current control circuit, thereby realizing the setting of personalized welding parameters to meet the welding requirements of various special scenarios. Otherwise, the welding process of the welding equipment is controlled based on the welding parameters determined by the parameter query module M200, and the automatically determined welding parameters are sent to the specific welding current control circuit.

[0083] When adjusting welding parameters, the operator can refer to the welding parameters determined based on the parameter query module M200 for fine-tuning. The determined welding parameters provide a reference for the welding operator, and the operator only needs to make a small amount of adjustment, which is more convenient and quicker than the operator directly setting the welding parameters.

[0084] After determining that the parameter adjustment module M500 receives the updated welding parameters input by the user, the welding control module M300 is further used to control the parameter display module M400 to display the updated welding parameters, and to update the pre-stored correspondence between the electrode diameter and the welding parameters according to the updated welding parameters. Therefore, the control system of this embodiment can adaptively update and optimize the pre-stored correspondence between the electrode diameter and the welding parameters according to the adjustment feedback of the operator, avoiding the operator from repeatedly adjusting the welding parameters, and is also conducive to the optimization control of the subsequent welding process.

[0085] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
