In the transfer cart according to the above embodiment, since the locking hole 321 of the fine adjustment plate 320 is further inserted with the limit pin 350, the fine adjustment plate 320 cannot be adjusted by translation in a normal state, and therefore, before the fine adjustment plate is positioned by the positioning mechanism 800, the limit pin 350 needs to be withdrawn from the locking block 321, or the tapered portion of the limit pin 350 needs to be positioned in the locking hole 321, so that the fine adjustment plate 320 has a space for translation.

As shown in fig. 7, 9 and 10, in particular, the hole-withdrawing of the limiting pin 350 is realized by an unlocking mechanism 2000, wherein the unlocking mechanism 2000 comprises a pneumatic clamping jaw 2100, and the pneumatic clamping jaw 2100 is integrally located at a middle position below the driving plate 830 of the positioning mechanism 800. The two clamping plates 2110 and 2120 of the pneumatic clamping jaw 2100 move in a direction perpendicular to the fine adjustment plate 320, that is, the whole of the two clamping plates is parallel to the fine adjustment plate 320, the clamping jaw cylinder 2130 of the pneumatic clamping jaw 2100 drives the two clamping plates to move towards or away from each other, the clamping plates 2110 and 2120 are further provided with clamping blocks 2130 on opposite surfaces, the pneumatic clamping jaw 2100 is slidably arranged on a rail 2200 extending perpendicular to the fine adjustment plate 320 and connected with a pull-down cylinder 2300 driving the pneumatic clamping jaw to slide along the rail in a reciprocating manner, and the rail 2200 and the pull-down cylinder 2300 are fixed on a supporting seat 2400 on the stand.

When the pneumatic jaw moves up and its two jaws open, the delimiting pins 350 can be inserted again into the locking holes 321 to achieve the repositioning of the trimming plate 320.

Since the moving stroke of the processing robot is often limited, in order to facilitate processing of different sizes, it is necessary to enable the workpieces on the workpiece tray 500 to be lifted to a certain height to compensate for the stroke of the processing robot.

In detail, as shown in fig. 7, a lifting mechanism 900 is further disposed on the vertical frame 700, the lifting mechanism 900 is configured to apply an upward lifting force to the workpiece tray 500 on the transplanting trolley to lift the workpiece tray 500 and separate the workpiece tray 500 from the fine adjustment plate 320, the lifting mechanism 900 includes two upward pushing mechanisms disposed on the vertical frame 700, the two upward pushing mechanisms on the two sides have the same structure, and the one upward pushing mechanism is described as an example below.

During operation, the cylinder 930 drives the transmission frame 920 to reciprocate, and since the position of the lifting wheel 940 is unchanged and the position of the lifting wheel in the chute 940 is changed constantly, the height of the lifting wheel 950 is changed constantly when the lifting wheel is at different positions of the chute 940, so as to drive the height of the lifting table 960 connected with the lifting wheel to change, when the lifting wheel 950 is lifted, the lifting table 960 drives the top post 980 thereon to be lifted, and the top post 980 drives the workpiece tray 500 to be lifted again.

S1, the claw cylinder 2130 of the unlocking mechanism 2000 is actuated to move the two clamping plates 2110, 2120 toward each other to clamp the U-shaped plate 395 therebetween, and then the cylinder shaft of the pull-down cylinder 2300 retracts to pull down the claw cylinder 2130 to pull down the U-shaped plate 395 clamped by the two clamping plates, so that the two limiting pins 350 on the U-shaped plate 395 are removed from the locking holes 321, and at this time, the fine adjustment plate 320 can be translated.

S2, the cylinder shafts of the two cylinders 820 of the positioning mechanism 800 extend to move the two pairs of V-shaped positioning slots 810 toward the rollers 360 opposite to the V-shaped positioning slots 810 until each V-shaped positioning slot 810 contacts one roller 360, so that the four V-shaped positioning slots 810 position the four rollers 360 to position the fine adjustment plate 320, and at this time, the position on the workpiece tray 500 on the floating plate 320 is repositioned to match the position of the processing robot at the station.

S3, the two cylinders 930 of the lifting mechanism 900 respectively drive the two transmission frames 920 to move along the guide rail 910, so that the lifting wheels 950 located in the inclined groove 940 move from the lower end to the upper end of the inclined groove 940, and the lifting wheels 950 lift the lifting platform 960 connected thereto, thereby driving the four top posts 980 to be respectively embedded into one positioning ring, and lifting the workpiece tray 500 to a target height along with the lifting of the top posts 980.

At this time, the processing robot may process, and after the processing is completed, the two cylinders of the jacking mechanism 900 drive the jacking post 980 to move down, so that the workpiece tray 500 falls back onto the support 300. The V-shaped detent 810 of the detent mechanism 800 is then repositioned to release the detent of the roller 360. Then, the pull-down cylinder 2300 of the unlocking mechanism is reset, the two clamping plates are opened to release the limitation on the U-shaped plate, and at the moment, the U-shaped plate can be kept in the state of being inserted into the locking hole under the action of the connecting rod, namely, the fine adjustment plate 320 can be adjusted to be aligned with the frame.

In addition, before the workpiece tray 500 is lifted, the manual latch needs to be pulled out from between the locking member 540 and the connecting member 380, so as to prevent the manual latch from affecting the adjustment of the fine adjustment plate 320.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
