[0028] When the conveying device is working, the conveying frame 2 can slide relative to the conveying driving member 1, and the conveying clip 3 can slide relative to the conveying frame 2, so that the conveying clip 3 has two-stage displacement, thereby increasing the conveying stroke of the conveying device, while reducing the size of the vending machine, ensuring that the conveying device has sufficient space to convey the meal tray. The conveying driving member 1 is driven to swing by the clamping driving component 4, thereby changing the spacing between the conveying clips 3, thereby facilitating the clamping of the product tray and improving the stability of the product tray during transportation.

[0029] A swing connection block 6-1 and a telescopic mounting plate 6-2 are installed on the base 6. The conveying drive member 1 is connected to the swing connection block 6-1 through a rotating shaft, thereby ensuring that the conveying drive member 1 can swing relative to the base 6.

The clamping cylinder 4-3 is connected to the guide block 4-1 and is used to drive the guide block 4-1 to lift and lower.

[0031] A first baffle 4-5, a second baffle 4-6 and a position detection member 5 are respectively provided on both sides of the guide block 4-1, wherein the first baffle 4-5 and the second baffle 4-6 are fixed on both sides of the guide block 4-1, and the two position detection members 5 are respectively fixed on the telescopic mounting plate 6-2. Preferably, the position detection member 5 is an infrared sensor, and the first baffle 4-5 and the second baffle 4-6 are adapted to the position detection member 5, that is, when the first baffle 4-5 is facing the position detection member 5, it is determined that the conveying clamp 3 is in a clamping state, and when the second baffle 4-6 is facing the position detection member 5, it is determined that the conveying clamp 3 is in a relaxed state.

[0032] Since the device needs to accurately pick up the target object in a smaller gap and minimize interference with other objects, after the conveying clamp 3 is extended to the target object, the conveying drive member 1 is driven to swing through the clamping drive assembly 4, so that the conveying clamp 3 is in close contact with the target object to avoid interference with surrounding objects.

[0033] A power assembly 7 is installed on the base 6. Preferably, the power assembly 7 is a servo motor. The power assembly 7 is connected to the conveying drive 1 through a spring coupling 8 to ensure that the power of the power assembly 7 can drive the conveying drive 1 to work during the swinging process of the conveying drive 1.

[0034] The conveying drive member 1 includes a conveying mounting plate 1-1 and a plurality of transmission gears 1-2. The transmission gears 1-2 are rotatably mounted on the conveying mounting plate 1-1. The power assembly 7 is connected to one of the transmission gears 1-2 through a spring coupling 8.
