[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] like Figure 1 As shown, the present application provides a work platform, including a workbench 100, a plurality of first universal wheels 200, a first positioning member 300 and a first clamping mechanism 400. The workbench 100 has a loading side, which is used for loading workpieces. Of course, when unloading, the corresponding workpieces can also be unloaded from the loading side. The plurality of first universal wheels 200 are respectively arranged on the workbench 100, and cooperate to support the workpieces. The first positioning member 300 is arranged on a side of the workbench 100 away from the loading side, and is used to stop and position the workpiece. The first clamping mechanism 400 is used to clamp and position the workpiece on the first universal wheel 200 on the first positioning member 300.

[0044] Furthermore, the first clamping mechanism 400 includes a first clamping member 410 and a first clamping driving structure 420. The first clamping member 410 is located on the loading side of the workbench 100 and is lower than the top of the first universal wheel 200 (i.e., the surface where the first universal wheel 200 contacts the workpiece) in the height direction. The first clamping driving structure 420 is drivingly connected to the first clamping member 410. The first clamping driving structure 420 can drive the first clamping member 410 to protrude out of the first universal wheel 200 in the height direction of the first universal wheel 200, and the first clamping driving structure 420 can drive the first clamping member 410 to move toward the direction close to the first positioning member 300.

[0045] It can be understood that the first clamping member 410 can be lower than the top of the first universal wheel 200 in the height direction of the first universal wheel 200 in the initial state. In this way, the workpiece can be loaded onto the first universal wheel 200 from the loading side where the first positioning member 300 is located. During this process, since the first clamping member 410 is lower than the top of the first universal wheel 200, the first clamping member 410 will not interfere with the workpiece during the loading process. After the workpiece is loaded onto the first universal wheel 200, the first clamping driving structure 420 can drive the first clamping member 410 to protrude out of the first universal wheel 200 in the height direction of the first universal wheel 200, so that the first clamping member 410 can contact the workpiece. Therefore, when the first clamping driving structure 420 drives the first clamping member 410 to move toward the direction close to the first positioning member 300, the first clamping member 410 can clamp the workpiece on the first universal wheel 200 onto the first positioning member 300.

[0046] It can be seen that in the work platform of the present application, a plurality of first universal wheels 200 are arranged on the workbench 100, and the plurality of first universal wheels 200 can cooperate with each other to support the workpiece on the work platform. At the same time, the universal wheels are beneficial for directly pushing the workpiece from one side of the workbench 100 to the work platform during the process of loading the workpiece onto the work platform. In addition, a first positioning member 300 is provided on a side of the workbench 100 away from the loading side for stopping and positioning the workpiece, and a first clamping member 410 is provided on the loading side of the workbench 100. The first clamping member 410 can protrude from the first universal wheel 200 in the height direction of the first universal wheel 200 under the action of the first clamping driving structure 420, and can move in the direction close to the first positioning member 300. In this way, the first clamping member 410 can be lower than the surface of the first universal wheel 200 that contacts the workpiece in the initial state, so that the workpiece can be moved from the side of the workbench 100 where the first clamping member 410 is located to the first universal wheel 200 for loading. After the workpiece is loaded onto the first universal wheel 200, the first clamping member 410 can protrude from the first universal wheel 200, and can move in the direction close to the first positioning member 300, so that the workpiece is clamped and positioned on the first positioning member 300, thereby realizing the loading of the workpiece. The workpiece loading method is simple and the cost is low.

[0047] Furthermore, in some embodiments, the first clamping drive structure 420 can be arranged on a side of the workbench 100 away from the first universal wheel 200. In this way, the first clamping drive structure 420 can be prevented from interfering with the workpiece during the loading and unloading process, and at the same time, it is convenient for the setting of the first clamping drive structure 420 and for the first clamping member 410 to be lower than the contact surface of the first universal wheel 200 with the workpiece in the initial state.

[0048] For example, the first universal wheel 200 may be disposed on the upper surface of the workbench 100 , and the first pressing driving structure 420 may be disposed on the lower surface of the workbench 100 .

[0049] Further, in some embodiments, the first pressing driving structure 420 may include a first pressing driving member and a second pressing driving member, the first pressing driving member and the second pressing driving member are respectively connected to the first pressing member 410 in driving manner, the first pressing driving member may drive the first pressing member 410 to protrude from the first universal wheel 200 in the height direction of the first universal wheel 200, and the second pressing driving member may drive the first pressing member 410 to move toward the direction close to the first positioning member 300. For example, the first pressing driving member may be a lifting cylinder or a rotating cylinder. When the first pressing driving member is a lifting cylinder, the first pressing driving member may drive the first pressing member 410 to rise to protrude from the first universal wheel 200. When the first pressing driving member is a rotating cylinder, the first pressing driving member may drive the first pressing member 410 to rotate to protrude from the first universal wheel 200. The second pressing driving member may be a clamping cylinder.

[0050] In some embodiments, the first clamping drive structure 420 may also be a rotary clamping cylinder such as Figure 1 The rotary clamping cylinder can drive the first pressing member 410 to move toward the direction close to the first positioning member 300 while performing a rotational motion.

[0051] See also Figure 1 The working platform may further include a second positioning member 500 and a second clamping mechanism 600 . The second positioning member 500 is disposed at one end of the working table 100 . The second clamping mechanism 600 is used to clamp the workpiece onto the second positioning member 500 .

[0052] For example, in some embodiments, the first positioning member 300 may be disposed on one side of the workbench 100 in a first direction, and the second positioning member 500 may be disposed on one end of the workbench 100 in a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0053] Furthermore, the second clamping mechanism 600 may include a second clamping member 610 and a second clamping driving structure 620. The second clamping member 610 is arranged at the other end of the workbench 100. The second clamping driving structure 620 can drive the second clamping member 610 to move toward the direction close to the second positioning member 500, so that the second clamping member 610 can press the workpiece onto the second positioning member 500.

[0054] In some embodiments, the second clamping drive structure 620 may be a clamping cylinder.

[0055] It can be seen that in the present application, the first clamping member 410 can press the workpiece onto the first positioning member 300, and the second clamping member 610 can press the workpiece onto the second positioning member 500. In some processes with higher requirements for workpiece positioning, the workpiece on the first universal wheel 200 can be positioned in different directions.

[0056] In some embodiments, a buffer member 700 may be further provided on the first positioning member 300 and / or the second positioning member 500 , and the buffer member 700 is used to buffer the workpiece when the workpiece is positioned.

[0057] For example, when the first pressing member 410 presses the workpiece onto the first positioning member 300, the buffer member 700 can buffer the workpiece to prevent the workpiece from being pressed. When the second pressing member 610 presses the workpiece onto the second positioning member 500, the buffer member 700 can buffer the workpiece to prevent the workpiece from being pressed. The buffer member 700 can be a hydraulic buffer or an oil pressure buffer.

[0058] See also Figure 1 The work platform can also have a lifting mechanism 800 , which is disposed on the workbench 100 and is used to lift the workpiece on the first universal wheel 200 .

[0059] It is understandable that since the workpiece is supported by the first universal wheel 200, when the workpiece requires more precise processing, the workpiece may have insufficient stability on the first universal wheel 200, so the lifting mechanism 800 can lift the workpiece, separate it from the first universal wheel 200, and support the workpiece.

[0060] Specifically, in some embodiments, the lifting mechanism 800 may include a lifting member 810 and a lifting drive structure 820. The workbench 100 is provided with a clearance hole 110. The lifting drive structure 820 is provided on the workbench 100. The lifting drive structure 820 is connected to the lifting member 810 and is used to drive the lifting member 810 to lift the workpiece on the first universal wheel 200 through the clearance hole 110. The lifting drive structure 820 may be a lifting cylinder.

[0061] Furthermore, there may be multiple lifting members 810, for example, four lifting members 810 may be provided, and the lifting drive structure 820 may simultaneously drive the four lifting members 810 through the connecting member to lift the workpiece. After the workpiece is lifted, the four lifting members 810 support the workpiece to ensure the stability of the support for the workpiece.

[0062] See also Figure 2 The present application also provides a loading and unloading assembly, including a moving trolley 1000 and a working platform in the above embodiments. The moving trolley 1000 may be provided with a plurality of second universal wheels 1100, which are used to support the workpiece, and the moving trolley 1000 can be moved to the loading side of the workbench 100, and the first universal wheel 200 on the workbench 100 is used to receive the workpiece on the second universal wheel 1100.

[0063] Specifically, the mobile cart 1000 can place the workpiece on the second universal wheel 1100, and then transfer the workpiece to the loading side of the workbench 100, that is, the side of the workbench 100 where the first clamping mechanism 400 is provided, and then the workpiece can be manually pushed from the second universal wheel 1100 to the first universal wheel 200, thereby transferring the workpiece from the mobile cart 1000 to the work platform.

[0064] It can be understood that since the workpiece is supported by the second universal wheel 1100 on the mobile trolley 1000 and is supported by the first universal wheel 200 on the working platform, in the process of transferring from the second universal wheel 1100 to the first universal wheel 200, the first universal wheel 200 and the second universal wheel 1100 are conducive to the movement of the workpiece. Therefore, the loading and unloading of the workpiece can be achieved only by manually pushing the workpiece.

[0065] See also Figure 2 The loading and unloading assembly may further include a guide member 900, which is disposed on the loading side of the workbench so that the workpiece can be smoothly transferred from the moving trolley 1000 to the work platform.

[0066] Furthermore, a guide bevel 910 may be provided on the guide member 900, and an end of the guide bevel 910 close to the first positioning member 300 is higher than the position where the first universal wheel 200 contacts the workpiece or is flush with the position where the first universal wheel 200 contacts the workpiece, and an end of the guide bevel 910 away from the first positioning member 300 is lower than the position where the second universal wheel 1100 contacts the workpiece or is flush with the position where the second universal wheel 1100 contacts the workpiece.

[0067] It can be understood that the guide member 900 of the above structure is conducive to transferring the workpiece from the moving vehicle 1000 to the working platform.

[0068] See also Figure 2 In some embodiments, the loading and unloading assembly may further include a displacement drive mechanism 1200 , which is drive-connected to the workbench 100 and is used to drive the workbench 100 to move toward or away from the moving vehicle 1000 .

[0069] For example, when the workpiece needs to be transferred from the moving trolley 1000 to the work platform, the displacement drive mechanism 1200 can drive the workbench 100 to move toward the moving trolley 1000, so that the workbench 100 can be as close to the moving trolley 1000 as possible, so as to push the workpiece carried by the second universal wheel 1100 on the moving trolley 1000 onto the first universal wheel 200 of the workbench 100. The displacement drive mechanism 1200 can be a telescopic cylinder.

[0070] In addition, see Figure 3The present application also provides a welding device, including a laser welding mechanism 1300 and the loading and unloading components in the above embodiments. The laser welding mechanism 1300 is arranged opposite to the working platform and is used to weld the workpiece on the working platform.

[0071] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some applications should be included in the protection scope of some applications.
