[0020] Example, by Figure 1-4 It is given that the utility model includes a U-shaped cache platform 1, a Tray 2 and two conveyor belts 3, the Tray 2 is located above the U-shaped cache platform 1, the conveyor belt 3 is located on the inner side of the U-shaped cache platform 1, a lifting platform 4 is installed inside the U-shaped cache platform 1, the lifting platform 4 is located between the two conveyor belts 3, four lifting mechanisms 8 are installed on the top of the U-shaped cache platform 1, a gantry 12 is fixedly connected to the top of the U-shaped cache platform 1, the gantry 12 is located between two adjacent lifting mechanisms 8 in front and behind, a fixing rod 13 is fixedly connected to the top of the gantry 12, a mounting plate 14 is fixedly connected to the bottom of the fixing rod 13, and two clamping and flipping mechanisms distributed front and back are installed on the bottom of the mounting plate 14.

[0021] The clamping and flipping mechanism includes a vertical telescopic rod 15, which is fixedly connected to the bottom of the mounting plate 14. A horizontal telescopic rod 16 is installed below the vertical telescopic rod 15. A fixing sleeve 17 is fixedly provided on the outer end of the horizontal telescopic rod 16. The horizontal telescopic rod 16 is fixedly connected to the bottom of the vertical telescopic rod 15 through the fixing sleeve 17. A connecting block 19 is fixedly connected to the end of the horizontal telescopic rod 16. A servo motor 18 is fixedly connected to the bottom of the connecting block 19. The output shaft of the servo motor 18 is fixedly connected to a concave plate 20. Two second cylinders 21 are fixedly connected to the top of the concave plate 20. The output shaft of the second cylinder 21 passes through the top of the concave plate 20 and extends to the inside of the concave plate 20. The vertical telescopic rod 15 and the horizontal telescopic rod 16 are both electric telescopic rods. The vertical telescopic rod 15 and the horizontal telescopic rod 16 can facilitate the adjustment of the position of the concave plate 20 so that it can accurately clamp the Tray 2. The second cylinder 21 can support the Tray 2 so that the Tray 2 clamped by the concave plate 20 is not easy to fall during the flipping process.

[0022] The lifting mechanism 8 includes a fixed block 9, which is fixedly connected to the top of the U-shaped cache platform 1. A first cylinder 10 is fixedly connected to the inner side of the fixed block 9. The output shaft of the first cylinder 10 is fixedly connected to a support block 11 through a coupling. The support block 11 is located on the side of the Tray 2 and extends to the bottom of the Tray 2. The lifting mechanism 8 can cooperate with the lifting platform 4 to lift the Tray 2 from the conveyor belt 3 and place it in mid-air.

[0023] The lifting platform 4 includes a support plate 6 and two electric push rods 5, the electric push rods 5 are fixedly connected to the bottom of the support plate 6, and a mounting groove 7 is opened at the top of the inner part of the U-shaped cache platform 1, and the electric push rods 5 are fixedly connected inside the mounting groove 7. The lifting platform 4 can lift the Tray plate 2 on the conveyor belt 3, and can also put the flipped Tray plate 2 back on the conveyor belt 3.

[0024] A groove is respectively provided at the two corners on the inner top of the U-shaped buffer platform 1, and the conveyor belt 3 passes through the groove. The opening of the groove facilitates the operation of the conveyor belt 3, and the conveyor belt 3 will not interfere with the U-shaped buffer platform 1 and the lifting platform 4 during operation.

[0025] The lifting platform 4 lifts up the Tray 2 on the conveyor belt 3, and then the lifting mechanism 8 operates to hold up the Tray 2. The lifting platform 4 returns, and the clamping and flipping mechanism operates to clamp and fix the Tray 2 and move it up a certain height and then flip the Tray 2. After the flipping is completed, the Tray 2 is sent back to the lifting mechanism 8, and the lifting platform 4 rises to hold the Tray 2 and the lifting mechanism retracts. The lifting platform 4 holds the Tray 2 and moves it down and places the Tray 2 on the conveyor belt. The above are the operating steps, and during the cooperation of the lifting platform 4, the lifting mechanism 8 and the clamping and flipping mechanism, the height, position and sequence of each step of the operation are designed and determined in advance, so that each component can automatically cooperate to operate.

[0026] Working principle:

[0027] When the conveyor belt 3 transports the tray 2 to the top of the lifting platform 4, the electric push rod 5 pushes the support plate 6 to rise. During this period, the lifting platform 4 will lift the tray 2 on the conveyor belt 3 until the height of the tray 2 is higher than the height of the lifting mechanism 8. Then the first cylinder 10 operates to extend its output shaft and push the support block 11 to the bottom of the tray 2. At this time, the lifting platform 4 can move downward while holding the tray 2. During this period, the tray 2 will fall on the support block 11 in the lifting mechanism 8 and be held, while the lifting platform 4 continues to return. In this state, the tray 2 is held by the four lifting mechanisms 8 and is in a suspended state. Then, the tray 2 can be clamped and turned over by the clamping and turning mechanism.

[0028] When the clamping and flipping mechanism is in operation, it is necessary to first control the vertical telescopic rod 15 to extend so that the concave plate 20 moves downward. When the concave plate 20 moves downward to be flush with the Tray 2, the horizontal telescopic rod 16 is controlled to extend so that the concave plate 20 moves close to the Tray 2 until the concave plate 20 is sleeved on the side of the Tray 2. The output shaft of the second cylinder 21 is controlled to extend to support the part of the Tray 2 located inside the concave plate 20, thereby clamping and fixing the Tray 2 between the concave plates 20 in the two clamping and flipping mechanisms. After the tray 2 is clamped and fixed, the vertical telescopic rod 15 can be controlled to retract and move the tray 2 upward for a distance to avoid interference between the tray 2 and the lifting mechanism 8 when the tray 2 rotates. The servo motor 18 is started so that its output shaft drives the concave plate 20 and the tray 2 to flip 180 degrees. After the tray 2 is flipped, the vertical telescopic rod 15 is used to drive the tray 2 to move downward until the tray 2 falls on the lifting mechanism 8 again. The clamping and flipping mechanism is operated in the reverse direction to make it separate from the tray 2 and return to its original position.

[0029] Start the lifting platform again to move it upward until it lifts the Tray 2 on the lifting mechanism 8, and then retract the supporting block 11 through the first cylinder 10 to pull it out from under the Tray 2. At this time, the lifting platform 4 can move downward with the Tray 2 in the return journey until the Tray 2 falls on the conveyor belt 3, and the overturned Tray 2 can be transported away by the conveyor belt 3.
