[0002] An exchange workbench is a device widely used in industrial production. It is mainly used for quickly replacing workpieces to improve production efficiency. An exchange workbench usually consists of a workbench surface, a drive system, a positioning system, and a control system. When the workpiece on one workbench surface is being processed, the other workbench surface is in a ready state for loading and unloading workpieces. After processing is completed, the drive system is activated to exchange the two workbench surfaces, and the new workpiece is conveyed to the processing area for continuous processing. According to the exchange method of the workbench surface, the exchange workbench can generally be divided into a parallel pulling type exchange workbench and a lifting type exchange workbench.

[0003] However, for the existing parallel pulling type exchange workbench to adapt to the automated loading equipment, the height of the workbench surface is mostly set relatively high, resulting in time-consuming and laborious manual loading by workers. Summary of the Utility Model

[0032] As described in the background art, the exchange workbench is a device widely used in industrial production. It is mainly used for quickly replacing workpieces to improve production efficiency. The exchange workbench usually consists of a workbench surface, a drive system, a positioning system, and a control system. When the workpiece on one workbench surface is being processed, the other workbench surface is in a standby state and can be used for loading and unloading workpieces. After the processing is completed, the drive system is activated to exchange the two workbench surfaces, and the new workpiece is conveyed to the processing area to continue the processing. According to the exchange method of the workbench surface, the exchange workbench can generally be divided into a parallel pulling type exchange workbench and a lifting type exchange workbench. However, for the existing parallel pulling type exchange workbench to adapt to the automated loading equipment, the height of the workbench surface is mostly set relatively high, resulting in time-consuming and laborious manual loading by workers and there being a certain safety risk.

[0033] See Figures 1 to 7As shown in the figure, to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides an exchange workbench. The exchange workbench includes: a frame 10, an exchange unit, and a lifting unit 30. Among them, a loading area and a processing area are provided on the frame 10; the exchange unit includes two workbench components 21. Both of the two workbench components 21 are movably installed on the frame 10 along the length direction of the frame 10. When one of the two workbench components 21 is located in the loading area, the other of the two workbench components 21 is located in the processing area. The workbench component 21 includes an outer frame component 211 and an inner workbench 212. The outer frame component 211 is movably installed on the frame 10, and the inner workbench 212 is placed on the outer frame component 211. The inner workbench 212 is used to place materials; the lifting unit 30 is provided on the frame 10 and is located in the loading area. A bearing structure is provided on the output end of the lifting unit 30. When the workbench component 21 is located in the loading area, the output end of the lifting unit 30 can carry the inner workbench 212 through the bearing structure and drive the inner workbench 212 to lift on the side of the outer frame component 211 away from the frame 10. The exchange workbench provided by this embodiment movably installs the two workbench components 21 on the frame 10 along the length direction of the frame 10, and sets the two workbench components 21 such that when one is located in the loading area, the other is located in the processing area, enabling workers to load and unload the workbench component 21 located in the loading area during the process of the external processing equipment processing the materials on the workbench component 21 located in the processing area, thereby effectively improving the production efficiency. At the same time, the exchange workbench provided by this embodiment sets the workbench component 21 to include an outer frame component 211 and an inner workbench 212, and movably installs the outer frame component 211 on the frame 10, and places the inner workbench 212 on the outer frame component 211, so that when the workbench component 21 is located in the loading area, the lifting unit 30 can carry the inner workbench 212 through the bearing structure and drive the inner workbench 212 to lift on the side of the outer frame component 211 away from the frame 10, thereby realizing the height adjustment of the inner workbench 212. Since the height of the inner workbench 212 provided by this embodiment is adjustable, the exchange workbench provided by this embodiment can be adapted to different models of automatic loading equipment, has strong versatility, and when the lifting unit 30 is not working, the height of the inner workbench 212 provided by this embodiment is relatively low, which is convenient for workers to perform manual loading.

The telescopic cylinder lifting device can push the inner workbench 212 to separate it from the outer frame component 211 and lift it on the side of the outer frame component 211 away from the frame 10. The specific structure of the telescopic cylinder lifting device is a conventional structure in the prior art and will not be elaborated here.
