[0018] like Figure 1As shown, a denim double-sided laser marking machine comprises: a workbench for carrying denim, including a first workbench 1 and a second workbench 2, the first workbench 1 and the second workbench 2 are driven by a position interchange device to interchange between a loading and unloading station 3 and a processing station 4; wherein the position interchange device comprises an upper track 5 and a lower track 6, the first workbench 1 is controlled by a first drive device 7 to move along the upper track 5 in the upper track 5, the second workbench 2 is controlled by a second drive device 8 to move along the lower track 6 in the lower track 6, and the second workbench 2 is controlled by a third drive device 9 to switch between the upper track 5 and the lower track 6; a laser marking device 10, located above the processing station 4, for laser marking the denim on the workbench located on the processing station 4; a control system 11, used to control the operation of the workbench and the laser marking device 10, which can be a PLC control system 11 and an XYZ control system 11. The upper track 5 is located above the lower track 6, and the two are arranged in parallel. In order to ensure that the laser marking device 10 maintains the same processing distance on the first workbench 1 and the second workbench 2, the first workbench 1 and the second workbench 2 need to be kept at the same horizontal plane during processing. Therefore, in order to keep the same horizontal plane, in order to allow the second workbench 2 to rise to the same horizontal plane as the first workbench 1, the width of the second workbench 2 with a lifting function must be less than the spacing between the upper rails 5, so that the second workbench 2 can rise to be flush with the first workbench 1. In this embodiment, the first drive device 7 and the second drive device 8 are the same drive output device, which are respectively connected to the first workbench 1 and the second workbench 2 through different transmission components. For example, the first workbench 1 is assembled on the upper belt of the transmission belt, and the second workbench 2 is assembled on the lower belt of the transmission belt. Then, when the transmission belt is operating, the upper belt moves to the left and the lower belt moves to the right to achieve left-right exchange of positions. The same is true when the transmission belt operates in the opposite direction.

[0019] The above technical solution further includes a semi-enclosed frame 12, which is used to semi-enclose the processing station 4 and is equipped with a smoke collection device 13.

[0020] In this embodiment, the laser marking device 10 is equipped with a CCD visual positioning device, which is used to take a photo of the denim carried on the workbench and then generate a laser marking path by the control system 11. The laser marking device 10 moves along the laser marking path and performs laser marking.

[0021] In this embodiment, the lower rail 6 is equipped with a base frame 14 controlled to move by a second driving device 8, a third driving device 9 is installed on the base frame 14, and the third driving device 9 is connected to the bottom surface of the second workbench 2 through a connecting rod 17 assembly. Specifically, the connecting rod 17 assembly includes a pair of rotating shaft 16 seats 15 installed on the base frame 14, a rotating shaft 16 installed on the pair of rotating shaft 16 seats 15, one end of the connecting rod 17 is fixedly installed on the rotating shaft 16, and the other end of the connecting rod 17 is rotatably installed on a connecting seat 18 on the bottom surface of the second workbench 2.

[0022] In this embodiment, a pulley 19 is mounted on the side of the base frame 14 and moves along the lower track 6 .

[0023] The working principle of the present invention is as follows: the workbench is controlled by the driving device, specifically, the first workbench 1 is controlled to move along the upper track 5 by the first driving device 7, the second workbench 2 is controlled to descend from the upper track 5 to the lower track 6 by the third driving device 9, and the second workbench 2 is controlled to move along the lower track 6 by the second driving device 8, and the denim on the first workbench 1 and the second workbench 2 are exchanged. For example, denim is placed on the first workbench 1, the first workbench 1 is exchanged with the second workbench 2, the denim is placed on the second workbench 2, and the first side of the denim on the first workbench 1 is laser marked at the same time, and then the first workbench 1 is exchanged with the second workbench 2, the denim on the first workbench 1 is turned over to the second side, and the denim on the second workbench 2 is processed at the same time, and the back and forth exchange is realized to realize continuous alternating laser marking.

[0024] The above embodiments are only for illustration rather than limitation of the present invention, so all equivalent changes or modifications made according to the method described in the scope of the present patent application are included in the scope of the present patent application.
