[0034] Figure 2 It is a schematic diagram of the internal modules of the handheld box in the handheld laser welding control box according to the embodiments of the present application. Detailed implementation manners

[0035] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings.

[0036] As Figure 1 and Figure 2 shown, the embodiments of the present application disclose a handheld laser welding control box with a wireless function, including a handheld box and a receiving box communicatively connected to the handheld box. A first control board is provided inside the handheld box. The first control board includes a first CPU module, a display input module, and a first signal transceiver module, and further includes a battery module for supplying power to the first control board. The receiving box is used for signal connection with an external laser welding device. A second signal transceiver module and a second CPU module are provided inside the receiving box;

[0037] The first CPU module, the display input module, and the first signal transceiver module are signal-connected. The first signal transceiver module and the second signal transceiver module are remotely signal-connected. The second signal transceiver module and the second CPU module are signal-connected;

[0038] The display input module is used to input control data for the external laser welding device;

[0039] The first signal transceiver module is used for data intercommunication with the second signal transceiver module;

[0040] The first CPU module is used to display data in the display input module in real time and transfer control parameters to the first signal transceiver module;

[0041] The second CPU module is used to collect various parameters of the external laser welding device and transfer control parameters to the external laser welding device.

[0042] Specifically, through the communication between the first signal transceiver module and the second signal transceiver module, various parameters of the laser welding device are displayed in real time on the display input module. When adjustment is required, the modified parameters are input on the display input module. After the first CPU module receives the modified parameters, it sends them through the first signal transceiver module, and they are received by the second signal transceiver module. The second CPU module sends the received modified data to the host of the laser welding device for parameter modification.

[0043] For example, the operator can adjust key parameters such as laser power, welding speed, pulse frequency, and wire feeding speed in real time through the operation interface on the control box at a welding position at a certain distance from the main device. At the same time, the control box can receive and display the working status of each device in real time, including the working status of the laser generator, the operating parameters of the cooling system, the working conditions of the wire feeding mechanism, etc., enabling the operator to timely understand the operating status of the device, discover potential problems in advance, and ensure the smooth progress of the welding work.

[0044] In this embodiment, it further includes a power acquisition module, and the power acquisition module is signal-connected to the battery module and the first CPU module;

[0045] The power acquisition module is used to collect the current power and display it on the display input module.

[0046] It also includes a power alarm module electrically connected to the first CPU module, and the power alarm module is used to give an alarm when the power is insufficient.

[0047] Specifically, the method of DMA (Direct Memory Access) can be used to collect power. This collection method is efficient and not interfered by the CPU. It can directly transfer data between the memory and peripherals. During the collection process, using DMA can directly transfer the data after ADC conversion to the memory without the CPU frequently participating in data transfer, thereby improving efficiency and reducing the CPU overhead in the first CPU module.

[0048] It should be explained that before use, the threshold for insufficient power can be set manually. For example, a reminder is given when it reaches 10%.

[0049] Specifically, the operator can intuitively view the current power in the display input module. When the power is lower than the set threshold, a prompt message will be automatically sent to remind the operator to replace the battery in time, avoiding the interruption of the welding work due to insufficient power and ensuring the continuity and stability of the work.

[0050] In this embodiment, it further includes a sleep module. The sleep module is used to connect to the first CPU module, and the sleep module includes a timing unit, a status detection unit, and a sleep unit;

[0051] The status detection unit is used to detect the working status of each module on the first control board. The timing unit is used to time the non-working status of each module on the first control board. The sleep unit controls the first control board to enter the sleep state according to the timing time of the timing unit.

[0052] That is, when the sleep module detects that no operation has occurred for each module in the control box within the preset time, the sleep module controls each module on the first control board to enter the sleep state.

[0053] For example, when the control box does not detect any operation within 5 seconds, it will automatically enter the sleep state. In the sleep state, most of the power-consuming components of the control box will stop working, and only the necessary monitoring circuits are retained, thus effectively reducing power consumption. When the operator operates the control box again, it can quickly wake up from the sleep state and resume normal operation without affecting the fluency of the operation.

[0054] In this embodiment, it further includes a first status light module signal-connected to the first control board, and the first status light module is used to display different states of the external laser welding device;

[0055] It further includes a second status light module signal-connected to the second control board, and the second status light module is used to display different states of the external laser welding device.

[0056] Specifically, the first status light module and the second status light module can display different states according to different instructions. For example, a constantly lit green light indicates that the device is operating normally; a flashing yellow light indicates that the device is in the standby state; a constantly lit red light indicates that the device has a fault, etc. This intuitive status display method enables the operator to quickly understand the working state of the device, improving the convenience and safety of the operation.

[0057] In this embodiment, both the first signal transceiver module and the second signal transceiver module are wireless communication modules, and the wireless communication module is a Wi-Fi module or a Bluetooth module.

[0058] Specifically, in this technical solution, a wireless communication technology with strong anti-interference ability is preferably adopted, such as Wi-Fi 6 or Bluetooth version 5.0 and above. Wi-Fi 6 adopts the orthogonal frequency division multiple access (OFDMA) technology, which can communicate with multiple devices simultaneously, improving network efficiency and stability; Bluetooth version 5.0 and above have significant improvements in transmission distance and anti-interference ability, which helps to ensure signal stability within the effective transmission distance.

[0059] In this embodiment, it further includes a signal amplifier and a directional antenna arranged at the signal transceiver ends of the first signal transceiver module and the second signal transceiver module.

[0060] Specifically, the directional antenna technology is adopted to enable the signal to be concentrated and transmitted in a specific direction, reducing signal divergence and loss, thereby increasing the transmission distance to a certain extent. At the same time, a signal amplifier is added to ensure that the signal maintains sufficient strength during transmission, and stable communication can be maintained even when there is interference or the distance is far.

[0061] The present invention also discloses a handheld box, which includes a first control board. The first control board includes a first CPU module, a display input module, and a first signal transceiver module, and also includes a battery module for supplying power to the first control board. The first CPU module, the display input module, and the first signal transceiver module are signal-connected.

[0062] The display input module is used to input control data for an external laser welding device.

[0063] The first signal transceiver module is used for data intercommunication with a second signal transceiver module.

[0064] The first CPU module is used to display data in real time in the display input module and transfer control parameters to the first signal transceiver module.

[0065] The handheld box in this structure solves the problem of conveniently sending instructions to the receiving box, and can realize remotely sending instructions into the receiving box, and the receiving box sends the instructions to the laser welding host.

[0067] A second signal transceiver module and a second CPU module are arranged in the receiving box.

[0068] The second CPU module is used to collect various parameters of the external laser welding device and transfer control parameters to the external laser welding device.

[0069] The receiving box in this structure solves the problem of conveniently receiving instructions sent by the handheld box. That is, in specific use, only need to connect this receiving box with the laser welding host, without the need to make a large-scale modification to the panel of the welding host, thus making it more convenient to use.

[0070] The present invention also discloses a control method for a handheld laser welding control box, including the above-mentioned handheld laser welding control box with wireless function. Through the communication between the first signal transceiver module and the second signal transceiver module, various parameters on the laser welding device are displayed in real time on the display input module. When adjustment is needed, the modified parameters are input on the display input module. After the first CPU module receives the modified parameters, it sends them through the first signal transceiver module, and they are received by the second signal transceiver module. The second CPU module sends the received modified data to the host of the laser welding device for parameter modification.

[0071] Through the design of modules such as the first signal transceiver module, the second signal transceiver module, and the display input module, this method can remotely monitor and adjust the parameters of the device, enabling operators to timely understand the operating status of the device, discover potential problems in advance, and ensure the smooth progress of the welding work.

[0072] In this embodiment, when the power acquisition module detects insufficient power, the power alarm module issues a prompt of insufficient power.

[0073] When the sleep module detects that no module in the control box has any operation within a preset time, the sleep module controls each module on the first control board to enter the sleep state.

[0074] The above design can automatically send a prompt message when the power is lower than the set threshold, reminding the operator to replace the battery in time to avoid the interruption of the welding work due to insufficient power, ensuring the continuity and stability of the work. At the same time, when the control box has no operation, it will automatically enter the sleep state, thereby extending the standby time of the control box.
