[0051] The motor wheel truss transport mechanism 3 includes a frame truss 30, a first slide 31 is slidably provided on the top of the frame truss 30, the first slide 31 is parallel to the length direction of the roller frame 12, a motor wheel clamp 32 with an up and down sliding function is slidably provided on the first slide 31, when the motor wheel clamp 32 clamps the motor wheel to move, it moves from above the roller frame 12 to above the flip group 20, a second slide 33 is fixed on the rear side column of the frame truss 30, the second slide 33 is perpendicular to the length direction of the roller frame 12, a pallet clamp 34 with an up and down sliding function is slidably provided on the second slide 33, when the pallet clamp 34 moves, it moves from above the roller frame 12 to above the placement frame 10.

[0052] like Figure 1As shown, during the implementation process, the motor wheel is usually placed on the pallet in a multiple-discharge manner, which is transported to the roller group 11 in the material conveying mechanism 1. The pallet moves the motor wheel on the pallet forward through the transverse roller 120, and is clamped by the motor wheel clamp 32 in the motor wheel truss handling mechanism 3, and is moved to the flip group 20, and further flipped. It is worth mentioning that before placing the flip group 20, the front and back sides can be identified by the visual sensor, so as to facilitate the front and back problems in the subsequent flip group 20. The operation of realizing the above-mentioned front and back identification is to use the rotation of the rotating cylinder in the motor clamp 32. Further, after the flip group flips the motor wheel horizontally, it continues to transport it, moves it to the motor wheel conveyor line mechanism 2, and is clamped by two support plates 220. The clamped motor wheel is identified by the industrial camera 24 on the top of the motor wheel. After identification, the angle with the placement requirement is calculated, and then it is clamped and rotated by the rotating clamp, and finally placed on the subsequent station, providing great convenience for the subsequent tire assembly.

[0053] In addition, after the pallet has taken the motor wheel on this layer, the pallet is subsequently transported by the pallet clamp 34 to prevent it from being placed on the placement rack 10 and automatically stacked.

When it reaches the clamping bracket 210, the support plates 220 on both sides move toward each other through sensor recognition and are clamped by four groups of nylon pads 221. At the same time, the four guide surfaces can fit the side walls of the motor wheel so that it can be firmly fixed, which is convenient for identification by the industrial camera.

The pallet clamp 34 is used for transporting pallets, and during the transporting process, the two pallet clamp arms are synchronously clamped so that the pallet is located in the middle, and after clamping, the pallet is placed on the placement rack by sliding on the slide.

[0065] Preferably, the motor wheel fixture 32 comprises a longitudinal slide bar 320 which is slidably mounted on the first slide 31 and slides up and down, and a motor wheel claw 321 driven by a rotary motor is arranged at the bottom of the longitudinal slide bar 320.
