[0099] The transfer device 100 of the present application, Figure 5 is a front view of the structure of a transfer device, as shown in Figure 1 and Figure 5 includes a vehicle-mounted platform 10 and a switching device 20 arranged on the vehicle-mounted platform 10.

[0100] The transfer device 100 can be used in a vehicle production fixture storage warehouse, which usually has multiple rows of warehouse shelves, each layer of the shelf has a storage position for holding the tray 262, and the fixture 261 for producing vehicle parts is fixedly connected to the tray 262. When a certain fixture 261 is needed for production, the transfer device 100 together with the vehicle-mounted platform 10 travels between the warehouse shelves in the warehouse and drives to the relevant storage position, and the vehicle-mounted platform 10 rises its double fork arms to the relevant storage position. The transfer device 100 of the present application starts to operate, which usually includes two working states:

[0101] One is the initial working state, that is, the first driving assembly 221 of the first moving platform 22 and the second driving assembly 231 of the second moving platform 23 are parked at the left end of the rack main body 211, as shown in Figure 6 , Figure 6 is a schematic view of the initial working state of the transfer device, which is an idle standby state or a state after the tray 262 is taken out and is ready to be transferred; the second is that the second moving platform 23 and the first moving platform 22 simultaneously extend to take the material 26, as shown in Figure 1 , the first moving platform 22 and the second moving platform 23 synchronously extend to the tray 262 of the storage position, when the double finger clamps of the clamping cylinder 2511 at the right end of the second moving platform 23 extend to the bottom of the clamping part on the left side of the tray 262, the vehicle-mounted platform 10 further rises its double fork arms and makes the double finger clamps of the clamping cylinder rise and insert into the slot of the clamping part on the left side and clamp, the first moving platform 22 and the second moving platform 23 synchronously retreat, during the retreat process, the fixture 261 and its tray 262 are dragged by the clamping of the second moving platform 23 and rely on the pulley set 212 of the rack 21 to slide to the middle part of the rack main body 211, as shown in Figure 7 , Figure 7 is a schematic view of the structure of the transfer device, five groups of pulley sets 212 are arranged on the top of the rack main body 211 on both sides to support the fixture 261 and its tray 262, when the left end of the fixture 261 and its tray 262 moves to the left end of the rack main body 211, the locking cylinder 2521 ejects its piston and tightly locks the tray 262, the vehicle-mounted platform 10 descends and drives away from the warehouse shelf and carries the fixture 261 and its tray 262 to the next link.

[0102] As described above, the first moving platform 22 and the second moving platform 23 can simultaneously extend and retreat to move left and right during the driving and moving of the driving assembly and the bearing assembly. This synchronous action mode saves time compared to the step-by-step action mode, and the length, stroke and speed of the extension and retreat of the first moving platform 22 and the second moving platform 23 can be set and managed accurately, so the operation efficiency can be improved.

[0103] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
