[0043] Referring to Figures 1 to 5 , the utility model embodiment provides a load platform with visual positioning device, and also provides a laser mold opening machine applying the load platform.

[0044] Specifically, as Figure 1 indicated, the load platform comprises a jig 100 for fixing a workpiece, a first moving module comprising a first lifting device 200, the jig 100 is connected to the first lifting device 200, the first moving module can drive the workpiece on the jig 100 to move to a machining position range, the first lifting device 200 is used to adjust the position of the workpiece on the jig 100 in the longitudinal direction, so that the workpiece reaches the machining position corresponding to the machining process, a visual positioning module comprising a second moving module and an image acquisition device 300, the second moving module comprises a second lifting device 400, as Figure 4 indicated, the image acquisition device 300 is connected to the second lifting device 400, the second moving module is used to drive the image acquisition device 300 to move to an image acquisition range, and the second lifting device 400 is used to adjust and keep the distance between the image acquisition device 300 and the jig 100 unchanged. Optionally, the second moving module can also be provided with a translation mechanism (not shown in the drawing), and the second lifting device 400 is connected to the translation mechanism (not shown in the drawing), and the image acquisition device 300 is driven to move to the image acquisition range of the jig 100 through the translation mechanism (not shown in the drawing).

[0045] The laser mold opening machine comprises a material loading platform and a laser module, wherein the laser module comprises two groups of laser light sources for providing two laser beams with energy difference, the material loading platform is arranged at the laser output end of the laser module, and the laser beams of the two groups of laser light sources are respectively used for different processes of the workpiece; the first lifting device 200 drives the jig 100 into the light beam focusing range of the laser beam.

[0046] It can be understood that the second lifting device 400 has a follow-up function. That is, after the workpiece is placed on the jig 100, before the first process is performed, the visual positioning module completes the first image positioning, at this time, the distance between the image acquisition end of the image acquisition device 300 and the jig 100 is L. When the workpiece completes the first process and switches to the second process, because the energy of the laser beams of the two groups of laser light sources has a difference, the focal lengths of the beams of the two groups of laser light sources have a difference when the beams are conducted to the workpiece, and in order to ensure that the processing position of the workpiece can be in the focusing range of the laser beam, the first lifting device 200 drives the jig 100 to ascend and descend according to the program instructions of the laser mold opening machine when the process is switched.

[0047] When the position of the jig 100 in the longitudinal direction changes, the distance L between the image acquisition end of the image acquisition device 300 and the jig 100 changes at this time. At this time, the second lifting device 400 drives the image acquisition device 300 to ascend and descend according to the program instructions of the laser mold opening machine until the distance between the image acquisition end of the image acquisition device 300 and the jig 100 is restored to L, so that the image information acquired by the image acquisition device 300 in each process can always remain consistent, avoiding repeated positioning and effectively improving production efficiency.

[0048] According to some embodiments of the present application, as shown in Figure 1 two image acquisition devices 300 are connected to the second lifting device 400, and the two image acquisition devices 300 acquire images of two visual angles of the jig 100 respectively to acquire two groups of diagonal positions of the workpiece on the jig 100. Specifically, the second moving module comprises two second lifting devices 400 and two image acquisition devices 300, the two image acquisition devices 300 are connected to the two second lifting devices 400 respectively, and the two image acquisition devices 300 acquire images of two visual angles of the jig 100 respectively to acquire two groups of diagonal positions of the workpiece on the jig 100.

[0049] According to some embodiments of the present application, as shown in Figure 1 the first moving module comprises an X-axis moving device 500, a Y-axis moving device 600 and a first lifting device 200, the Y-axis moving device 600 is arranged on the X-axis moving device 500, and the first lifting device 200 is arranged on the Y moving device.

[0050] It can be understood that the three-axis movement of the jig 100 is realized through the cooperation of the first lifting device 200, the X-axis moving device 500, and the Y-axis moving device 600.

[0051] In this application, the specific structure of the first lifting device 200, the X-axis moving device 500, and the Y-axis moving device 600 is not specifically limited. Optionally, the optional motor cooperates with the screw rod to realize the position adjustment of the jig 100.

[0052] According to some embodiments of the present application, as shown in Figure 5 The jig 100 includes an adsorption base 110 with a cavity and an adsorption power device (not shown in the figure). Specifically, the adsorption base 110 is provided with an adsorption hole 111 communicating with the cavity, and the adsorption power device (not shown in the figure) is connected with the cavity.

[0053] It can be understood that the cavity is connected with the outside through the adsorption hole 111, and the adsorption power device (not shown in the figure) is connected with the cavity. The adsorption power device (not shown in the figure) is used to generate a negative pressure adsorption force in the cavity to fix the workpiece on the adsorption base 110. When the workpiece is placed on the adsorption base 110 and covers the adsorption hole 111, the adsorption power device (not shown in the figure) is started and the air in the cavity of the adsorption base 110 is discharged, so that the cavity of the adsorption base 110 is in a negative pressure state, thereby firmly adsorbing and fixing the workpiece on the adsorption base 110. Through the adsorption fixing mode, the surface of the workpiece can be prevented from being scratched, and the quality of the product can be ensured.

[0054] It should be noted that the adsorption force generated by the adsorption jig 100 on the workpiece is adjustable, and the user can adjust the adsorption force by adjusting the parameters of the adsorption power device (not shown in the figure).

[0055] According to some embodiments of the present application, as shown in Figure 2 The laser module includes a first light source 700, a second light source 800, and a laser output device 900. A light path switching device 1000 is arranged between the first light source 700, the second light source 800, and the laser output device 900. The light path switching device 1000 is used to switch the connection between the first light source 700, the second light source 800, and the laser output device 900. The laser beams output by the first light source 700 and the second light source 800 can pass through the laser output device 900 to process the product. The laser beams output by the first light source 700 and the second light source 800 have energy differences. Specifically, the first light source 700 has a light propagation line between the first light source 700 and the laser output device 900. The light beam of the first light source 700 passes through the light propagation line and the laser output device 900 to process the product. The light path switching device 1000 can be on the light propagation line. The light path switching device 1000 is used to make the light beam of the second light source 800 pass through the light propagation line and the laser output device 900 to process the product.

[0056] It can be understood that the application can realize the switching use of two laser light sources through the optical path switching device 1000. By integrating the two laser light sources on the same machine, the laser light sources are switched in turn to realize that the workpiece can complete the machining process in sequence in the same machining station or the same machining equipment, and the user does not need to repeatedly switch different equipment according to different machining processes of the workpiece.

[0057] That is, by setting a switching device to switch the laser beams of different energies into the laser head, different types of lasers can be emitted from a single laser head, different laser source machining effects can be realized, different machining needs can be met, the utilization rate of a single laser head can be greatly improved, multiple machines are avoided to meet different machining needs, the functional integration of the equipment is improved, the equipment cost, maintenance cost and labor cost are effectively reduced, and multiple laser light sources are concentrated on the same machine, which can effectively save the occupied space of the equipment.

[0058] Specifically, the optical path switching device 1000 includes a movable first reflecting piece 1010. When the first reflecting piece 1010 moves to the light propagation line, the first reflecting piece 1010 conducts the light beam of the second light source 800 to the laser output device 900. Further, the first reflecting piece 1010 can also rotate, and the refractive angle of the first reflecting piece 1010 is adjusted to ensure that the light beam of the second light source 800 can accurately enter the laser output device 900.

[0059] According to some embodiments of the application, the light propagation line includes a second reflecting piece 1020, the second reflecting piece 1020 conducts the light beam of the first light source 700 to the laser output device 900, and the optical path switching device 1000 can be located between the second reflecting piece 1020 and the laser output device 900. Specifically, as shown in Figure 2 In order to further improve the compactness of the equipment and avoid excessive space occupied by the equipment, the layout of the first light source 700, the optical path switching device 1000 and the second light source 800 can be distributed in an L-shaped structure, and the second reflecting piece 1020 can refract the light beam of the first light source 700 in multiple segments, so that the light beam of the first light source 700 can smoothly and accurately enter the laser output device 900.
