[0041] In some embodiments of this application, a second prompting device is also included, wherein both the two laser displacement sensors 620 and the second prompting device are connected to the controller. The second prompting device is used to issue a second prompting message, which informs the user that the rectangular workpiece 10 currently located on the bearing surface is not aligned correctly, and the user needs to adjust and align the rectangular workpiece 10 after receiving the second prompting message. A Cartesian coordinate system is pre-established on the bearing surface, with the X-axis parallel to the width direction of the workpiece bearing platform 100 and the Y-axis parallel to the length direction of the workpiece bearing platform 100. The rectangular workpiece 10 being aligned correctly means that the two connected sides of the rectangular workpiece 10 located on the bearing surface are parallel to the length and width directions of the workpiece bearing platform 100, respectively.

[0042] The measurement method of the plate width measuring device 600 includes a sequential alignment detection stage and a plate width measurement stage. Please refer to the appendix. Figure 6 The specific measurement method is as follows: The gantry 200 drives two laser displacement sensors 620 to move from the rectangular workpiece 10 toward the rectangular workpiece 10 on one side along the length of the workpiece support platform 100. During the movement, the controller determines whether the two laser displacement sensors 620 detect the rectangular workpiece 10 at the same time. If they do, the controller determines that the rectangular workpiece 10 is aligned on the support surface. Otherwise, the controller determines that the rectangular workpiece 10 is not aligned on the support surface. At this time, the controller issues a second prompting message. After the user adjusts the position of the rectangular workpiece 10, the above steps are repeated until the rectangular workpiece 10 is aligned. Two laser displacement sensors 620 simultaneously move a first predetermined distance from the first side to the second side along the length direction of the workpiece support platform 100 of the rectangular workpiece 10. After moving the first predetermined distance, the two laser displacement sensors 620 then move away from each other along the width direction of the workpiece support platform 100 of the rectangular workpiece 10. The initial position coordinates (X1, Y1) and the final displacement coordinates (X2, Y2) of the movement path of one laser displacement sensor 620 on the rectangular workpiece 10, and the initial position coordinates (X3, Y3) and the final displacement coordinates (X4, Y4) of the movement path of the other laser displacement sensor 620 on the rectangular workpiece 10, can be calculated to find that the endpoint coordinates of point A are (X2, Y1) and the endpoint coordinates of point B are (X4, Y3). Two laser displacement sensors 620 simultaneously move a second predetermined distance from the second side of the rectangular workpiece 10 to the first side along the length direction of the workpiece support platform 100. After moving the second predetermined distance, the two laser displacement sensors 620 then move away from each other along the width direction of the workpiece support platform 100 and out of the rectangular workpiece 10. The initial position coordinates (X5, Y5) and the final displacement coordinates (X6, Y6) of the movement path of one laser displacement sensor 620 on the rectangular workpiece 10, and the initial position coordinates (X7, Y7) and the final displacement coordinates (X8, Y8) of the movement path of the other laser displacement sensor 620 on the rectangular workpiece 10, can be calculated to find that the endpoint coordinates of point C are (X6, Y5) and the endpoint coordinates of point D are (X8, Y7). Based on the coordinates of the four endpoints, the length of the rectangular workpiece 10 is calculated to be X4-X2 or X8-X6, the width of the rectangular workpiece 10 is Y5-Y1 or Y7-Y3, and the length of the diagonal can be calculated using the Pythagorean theorem.

The aforementioned vacuum cleaner can adsorb and remove dust from inside the dust cover to prevent dust pollution from affecting the health of workers.

[0045] The operation process of the welding and grinding integrated machine provided in this application embodiment is as follows: The rectangular workpiece 10 located on the bearing surface is checked by the plate width measuring device 600 to see if it is properly positioned. The width of the rectangular workpiece 10, which is in the correct position, is measured by the width measuring device 600. The rectangular workpiece 10 is front-side welded using welding device 300 pairs; The rectangular workpiece 10 is flipped over, and the weld is ground and cleaned by the grinding device 500. The rectangular workpiece 10 is reverse-side welded using a welding device consisting of 300 pairs of welding units.
