[0032] In order for those skilled in the art to better understand the embodiments of the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] Figure 1 A structural schematic diagram of an interactive system of a handheld laser welder is provided for an embodiment of the present application. As shown in Figure 1 The interactive system of the handheld laser welder includes the operation panel 1, the controller 2 and the memory 8. The operation panel 1 further includes the first display component 3, the second display component 4 and the third display component 7.

[0034] The controller 2 is used to provide computing and control capabilities.

[0035] The operation panel 1 is in communication connection with the controller 2, and the controller 2 is in communication connection with the memory.

[0036] In the embodiment, the interaction system further comprises a communication interface, which can be used to connect computers for information interaction.

[0037] The memory 8 in the embodiment pre-stores a plurality of preset welding process package data. The operation panel 1 comprises a plurality of functional devices. In addition to the first display component 3, the second display component 4, and the third display component 7 for displaying data as described above, the operation panel 1 further comprises functional components such as a button component 5 and a knob component 6.

[0038] The memory 8 stores a plurality of process packages. Each process package carries a unique identification code corresponding to the process package data. The unique identification code is used to enable the controller to accurately read, modify, and reset the process data package in the memory 8.

[0039] In the embodiment, the controller 2 can respond to an operation request from the operation panel. The operation request is derived from the operation of various possible functional components and can be used to select a preset welding process package data, change the parameters of the preset welding process package data, save the process package data, and reset the process package data. The process package data in the above-mentioned operations such as saving the process package data and resetting the process package refers to the preset process package data after the parameters are modified.

[0040] In the embodiment, the controller 2 is in communication connection with the welding system. The controller 2 further controls the welding system based on the operation request. The welding system comprises a sensor for collecting environmental parameters, a laser generator for emitting laser, and a temperature control module for controlling the welding temperature.

[0041] The controller 2 can control the laser generator and the temperature control module through a computer program and receive data from the sensor. The data includes environmental parameters and real-time welding parameters.

[0042] In the embodiment, the memory 8 pre-stores a plurality of pre-stored welding process package data. The pre-stored welding process package data is the parameter preset by the handheld laser welder according to the main working scene, different welding materials, and welding requirements when the handheld laser welder is shipped. The pre-stored welding process package data can basically meet the use scene of most handheld laser welders and reduce the operation requirements of the operator. However, in some special use scenes, the operator can also modify the pre-stored welding process package data through the operation of the above-mentioned functional components, thereby increasing the use range of the handheld laser welder. The modified data can be stored to form a new process package.

[0043] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be exemplarily described below with specific embodiments. It should be noted that the specific embodiments listed below can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0044] Figure 2 The flowchart of the interaction method of the handheld laser welding machine provided for an embodiment of the present application is shown. The execution subject of the embodiment is the operation panel 1 and the controller 2 in Figure 1 As shown in Figure 2 , the interaction method of the handheld laser welding machine includes the following steps.

[0045] S110, the controller reads first data corresponding to a first operation request from the memory in response to the first operation request from the operation panel, and sends the first data to the display component.

[0046] In the embodiment, the first operation request is mainly input through the button component in the function component, which is composed of four independent physical buttons. In other embodiments of the present application, the first operation request can also be input and obtained through liquid crystal screen control or pressable knobs, etc. The four independent physical buttons include a first switching button and a second switching button.

[0047] In the embodiment, the first operation request is specifically selecting and confirming a plurality of preset welding process package data pre-stored in the memory through the first switching button and the second switching button. After receiving the first operation request, the controller reads the selected preset welding process package data from the memory and sends the preset welding process package data to the second display component and the third display component for display.

[0048] The preset welding process package data includes welding process package types, welding package process package names, and welding parameters, etc.

[0049] The welding process package types and the welding process package names, etc. are sent to the second display component for display, and the welding parameter data is sent to the third display component for display.

[0050] In the first operation, the first switching button knob and the second switching button knob can be operated and input in a short pressing manner.

[0051] In another embodiment provided by the present application, the plurality of preset process package data stored in the memory is pre-divided into a plurality of groups, the group is selected by long pressing the first switching button and the second switching button, and the preset process package data is selected in the group by short pressing.

[0052] In the embodiment, after the controller reads the selected preset welding process package data from the memory, the welding process package data is saved in the cache of the controller. When the handheld laser welder is started next time, the controller will read the welding process package data from the cache as the current welding process package data, thereby simplifying the operation of the handheld laser welder.

[0053] In the embodiment, the first data is the selected preset welding process package data, and the controller controls the welding system based on the preset process package data.

[0054] In the embodiment, the first data is the selected preset welding process package data, and the controller controls the welding system based on the preset process package data.

[0055] In the embodiment, the preset process package data includes welding parameters such as light output power, swing frequency, and swing amplitude.

[0056] In the embodiment, the relevant data includes real-time welding parameters, device state information data, and warning information data.

[0057] In the embodiment, the device state information data includes light output state, gas state, interlock state, warning state, and abnormal state.

[0058] In the embodiment, the warning information data is detailed information of the warning state and the abnormal state, such as temperature being too high.

[0059] In the embodiment, the real-time welding parameters are sent to the third display component for display, the device state information data is sent to the first display component for display, and the warning information data is sent to the second display component for display.

[0060] More preferably, S130 specifically includes:

[0061] S131, the controller controls the laser generator based on the first data.

[0062] In the embodiment, the controller controls welding parameters such as light output frequency, swing frequency, and swing amplitude of the laser generator based on the currently selected welding process package data.

[0063] S132, the sensor collects the environmental parameters in real time and sends the environmental parameters to the controller.

[0064] In the embodiment, the sensor of the handheld laser welder collects the environmental parameters around the welder in real time and sends them to the controller. The environmental parameters include the real-time collected environmental temperature, so that the controller can make real-time adjustment to the laser generation power, frequency, and other parameters based on the external environmental temperature.

[0065] S133, the controller performs fuzzy control on the temperature control module based on the environmental parameters.

[0066] In the embodiment, the controller controls the temperature control module based on the received real-time environmental temperature parameter collected by the sensor and according to the fuzzy control table.

[0067] The fuzzy control table is stored in the storage, and the controller reads the fuzzy control table from the storage and controls the temperature control module when the welding work starts.

[0068] The main component of the temperature control module is a compressor, and the controller can control the compressor to be frequency-converted to meet the temperature requirement during the welding work through the fuzzy control table.

[0069] The controller generates fuzzy set data after fuzzifying the environmental temperature parameter and the light output parameter; calls corresponding fuzzy control rules based on the fuzzy set data in the fuzzy control rule table; and generates the first temperature control strategy after defuzzifying the fuzzy control rules to control the temperature control module.

[0070] S134, the controller sends the related data to the display component.

[0071] In the embodiment, the related data is real-time welding parameter, including real-time light output frequency, real-time swing frequency, and real-time swing amplitude. The above three welding parameters will be sent to the third display component for display. In addition to the above three welding parameters, if the welding work is abnormal, for example, light output is abnormal, gas is abnormal, welding is abnormal, temperature is abnormal, etc., the controller will send warning information to the first display component for display, and send detailed information of the warning information to the second display component for display.

[0072] In the embodiment, the controller controls the welding machine system to work according to the welding process package data selected by the operation request, and adjusts the real-time welding parameter of the welding system through fuzzy control according to the environmental parameter such as environmental temperature, especially the temperature control module in the welding system, so that the handheld laser welding machine can respond to the external environmental parameter in real time, avoiding the influence of external environmental factors on the normal work of the welding machine. The controller controls the temperature control module through the fuzzy control table, so that the temperature control module responds to the change of the environmental parameter and the welding process package parameter in time, adjusts the temperature control strategy in time, and prevents the welding machine from overheating and over-adjusting due to untimely temperature control.

[0073] The real-time parameter is temporarily stored as real-time data in the internal cache and displayed in the display component. When the process ends, the real-time parameter does not cause coverage and other influences on the first data in the storage, so as to ensure that the welding machine can automatically perform fuzzy control adjustment every time laser welding is performed, so as to adapt to the real-time welding environment.

[0074] Figure 4The flowchart of the handheld laser welding interaction method provided for another embodiment of the present application is similar to the above embodiment, but after the step S110 and before the step S130, it further includes:

[0075] S120, when receiving a second operation request for modifying the first data, the controller modifies the first data based on the second operation request, generates second data, and sends the second data to the display component.

[0076] In the embodiment, the second operation request is mainly input through the knob component in the function component to modify the first data.

[0077] In the embodiment, after the preset welding process package data is selected in the step S110, the preset welding process package data can be modified by rotating the knob component, the modified welding process package data is generated, and the modified process package data is sent to the third display component for display.

[0078] The knob component includes a first knob for modifying the light output frequency, a second knob for modifying the swing frequency, and a third knob for modifying the swing amplitude.

[0079] In the embodiment, the clockwise rotation of the knob component increases the corresponding parameter by one unit value, and the counterclockwise rotation of the knob component decreases the corresponding parameter by one unit value; the knob can also adopt a variable speed mode for rapid adjustment and accurate adjustment.

[0080] S121, the controller saves the second data to the memory according to the instruction.

[0081] In the embodiment, after the modification of the preset welding process package data is completed, the modified welding process package data can be saved to the data storage area of the memory, and the modified welding process package data is backed up in the data backup storage area.

[0082] After the storage is completed, the data storage area and the data backup area of the memory are refreshed.

[0083] The function of saving the modified welding process package data to the memory is completed by the third button in the button component to input the operation request.

[0084] In the embodiment, the third button is arranged below and to the left of the second display component, and after the modification of the preset welding process package data is completed, the third button is pressed for a short time to save the modified welding process package data to the memory.

[0085] In the embodiment, the memory is divided into two areas, one is a data storage area, and the other is a data backup storage area. Therefore, all preset welding process package data is stored in the two storage areas at the same time, and each data package has the same or a unique corresponding identification code in the two storage areas. The modified welding process package data covers the preset welding process package data in the welding process package data storage area, but the corresponding preset welding process package data is still stored in the welding process package data backup storage area.

[0086] In the embodiment, after the modified welding process package data is saved to the memory, the controller allocates a new unique identification code to the modified welding process package data. When the controller reads the first data corresponding to the first operation request from the memory according to the first operation instruction, the controller selects the corresponding first data based on the identification code and sends it to the display component, so as to meet the needs of the operator's custom settings and direct calls.

[0087] S122, the controller calls the corresponding first data in the data backup storage area based on the identification code and covers the second data with the corresponding identification code in the data storage area, so as to restore the second data to the first data.

[0088] In actual operation, the preset welding process package data may be modified incorrectly. At this time, the modified welding process package data can be restored to the preset welding process package data through the function of resetting the welding process package data.

[0089] The function of resetting the welding process package data is completed by inputting an operation request through the fourth button in the button component.

[0090] In the embodiment, the fourth button is arranged below and to the right of the second display component. After the preset welding process package data is modified, the fourth button is pressed for a short time to restore the modified welding process package data to the preset welding process package data.

[0091] In the embodiment, the specific way of restoring the modified welding process package data to the preset welding process package data is to cover the modified welding process package data with the corresponding preset welding process package data stored in the welding process package data backup storage area, so as to achieve the purpose of restoring the data.

[0092] After the restoration operation is performed, the data storage area in the memory is refreshed.

[0093] In this embodiment, after selecting a pre-stored welding process package data, or after modifying and saving the pre-stored process package data, the controller will save the currently used welding process package data to the controller's internal cache. The data in the internal cache will not be lost due to the handheld laser welding machine being turned on and off. After the welding work is completed, when the welding machine is turned on again, the controller will directly read the above welding process package data from the internal cache as the currently used welding process package data, which simplifies the operation of the handheld laser welding machine and makes it convenient for operators to use.

[0094] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of a process package selection, storage, and reset interface provided in one embodiment of this application. Figure 3 As shown, the interface includes a welding package type bar, a welding package name bar, a warning message bar, a welding package storage prompt area, and a welding package reset prompt area. The welding package storage prompt area and the welding package reset prompt area are located directly above the corresponding third and fourth buttons, making it easy to intuitively identify the function of each button.

[0095] In this embodiment, operators can freely modify welding parameters based on pre-stored welding process package data according to different usage scenarios, and save the modified welding process package data. A portion of the original pre-stored welding process package data is retained in memory for later use. Furthermore, in case of operator error in modifying the pre-stored welding process package data, the data can be reset, greatly increasing the operator's error tolerance during operation.

[0096] In this embodiment, the operator can complete all operations on the welding process package data simply by using the button and knob components. The operator does not need to remove protective gloves to perform any touch operations, which ensures the safety of the operator when performing welding operations, greatly simplifies the operation, and reduces the difficulty of operation for the operator.

[0097] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
