It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.

[0035] Figure 2 A structural block diagram of an optical center correction device for a handheld laser welding machine provided in an embodiment of the present application is shown. DETAILED DESCRIPTION

[0036] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0037] Before using a handheld laser welding machine, because transportation or handling may cause the motor to rotate slightly, or interference and other factors may cause the optical center to shift, and when performing related operations, if the optical center is not in the center or shifts far from the center, it is easy for the laser to directly hit the edge of the lens group and burn the flood seal, or the laser hits the scale tube and burns through the tube wall, and even causes laser injuries.

[0038] Based on this, an embodiment of the present application provides an optical center correction method and device for a handheld laser welding machine, which automatically adjusts the optical center to the center after the device is turned on or restarted after power failure, thereby ensuring that the optical center is in the center or center position to reduce the burning of welding gun components and temperature alarms caused by polarized light.

[0039] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] See also Figure 1 , Figure 1 A flow chart of an optical center correction method for a handheld laser welding machine provided by an embodiment of the present application is shown. Specifically, a detection fixture can be detachably connected to the nozzle of the handheld laser welding machine, and the detection fixture includes a photosensitive sensor and an operational amplifier circuit, the photosensitive sensor is used to convert the light intensity of the red positioning laser emitted by the handheld laser welding machine irradiated thereon into an analog voltage, and the operational amplifier circuit is used to amplify the analog voltage to obtain the amplified analog voltage; the optical center correction method is applied to a control device in the handheld laser welding machine, and the handheld laser welding machine includes a control device and a galvanometer motor controlled by the control device; the optical center correction method includes:

[0041] Step S110, while controlling the sending of a red positioning laser to the photosensitive sensor, adjusting the angle of the galvanometer motor to a minimum negative angle.

[0042] Specifically, after starting up or restarting after power failure, if the user determines through observation that the position of the optical center of the handheld laser welding machine is not at the center of the welding nozzle or is offset from the center by a large amount, the user can install the detection tooling at the nozzle of the welding gun head of the handheld laser welding machine to turn on the automatic optical center calibration function in the welding machine's system.

[0043] After the optical center calibration is enabled, the control device can adjust the angle of the galvanometer motor to the minimum negative angle. The specific direction of the negative angle can be set according to actual needs. For example, when the negative angle of the galvanometer motor is on the right and the motion cycle of the galvanometer motor is from -15 degrees to +15 degrees, the control device can adjust the angle of the galvanometer motor to -15 degrees.

[0044] It should be noted here that the position of the galvanometer motor is determined by the analog voltage, and the only movement of the galvanometer motor is angle change. The zero-degree position of the galvanometer motor corresponds to the position when the analog voltage is 0, and the minimum angle is the limit position that the motor can reach corresponding to the minimum analog voltage value output by the system. This angle corresponds to a negative angle. Due to the long use time and the vibration of the motor during operation, there will be a deviation between the zero point of the motor and the actual center point.

[0045] Step S120, controlling the galvanometer motor to move from the minimum negative angle to the maximum positive angle of the galvanometer motor according to the preset step angle value, and recording the detected amplified analog voltage each time the angle is adjusted.

[0046] It should be understood that the specific value of the preset step angle value can be set according to actual needs, and the embodiments of the present application are not limited to this.

[0047] For example, in a system with a minimum resolution of Therefore, the preset step angle value for each movement can be 0.0004 degrees.

[0048] To facilitate understanding of step S120, a specific embodiment is used to describe it below.

[0049] Specifically, the control device controls the galvanometer motor to move from the minimum negative angle (for example, -15 degrees) to the maximum positive angle (for example, +15 degrees) of the galvanometer motor according to a preset step angle value, and each time it moves according to the preset step angle value, the amplified analog voltage sent by the amplifier circuit is obtained and recorded.

[0050] Step S130 , converting each of the amplified analog voltages into a digital value, and determining the maximum digital value.

[0051] Step S140, determining the adjusted center point position based on the angle of the galvanometer motor corresponding to the maximum digital value.

[0052] Specifically, it is determined whether the maximum digital quantity is less than or equal to the preset digital quantity; if it is determined that the maximum digital quantity is less than or equal to the preset digital quantity, the angle of the galvanometer motor corresponding to the maximum digital quantity is determined as the adjusted center point position. The specific value of the preset digital quantity can be set according to actual needs, and the embodiments of the present application are not limited thereto. For example, the preset digital quantity can be 5000.

[0053] It should be noted here that the present application can execute steps S120 to S140 once, or can repeat steps S120 to S130 multiple times, and then determine the average value of the largest digital quantity based on step S130 after multiple repetitions, and determine the angle of the galvanometer motor corresponding to the average value of the largest digital quantity as the adjusted center point position.

[0054] For example, steps S120 to S130 may be repeatedly performed multiple times to obtain multiple maximum digital quantities, that is, multiple cycles may be repeatedly performed multiple times. Furthermore, it is determined whether each of the multiple maximum digital quantities is within the preset digital quantity range;

[0055] If there is a maximum digital quantity that is not within the preset digital quantity range among multiple maximum digital quantities, the maximum digital quantity that is not within the preset digital quantity range is deleted from all the maximum digital quantities to obtain the remaining maximum digital quantities, and the average value of all the maximum digital quantities in the remaining maximum digital quantities is calculated, and the average value is used as the final maximum digital quantity, and the angle of the galvanometer motor corresponding to the final maximum digital quantity is determined as the adjusted center point position. Among them, the specific range of the preset digital quantity range can be set according to actual needs, and if the current maximum digital quantity is not within the preset digital quantity range, it can be determined that the measurement of the current maximum digital quantity is interfered by the outside world, so that the measured current maximum digital quantity is inaccurate, so it needs to be deleted.

[0056] If each of the multiple maximum digital quantities is within the preset digital quantity range, the average of all the maximum digital quantities among the multiple maximum digital quantities is calculated, and the average value is taken as the final maximum digital quantity, and the angle of the galvanometer motor corresponding to the final maximum digital quantity is determined as the adjusted center point position.

[0057] Therefore, with the help of the above technical solution, the present application automatically adjusts the optical center to the center after the equipment is turned on or restarted after power failure, thereby ensuring that the optical center is in the center or center position to reduce the burning of welding gun components and temperature alarms caused by polarized light.
