The end of the hanging rod 11 is a tapered end 12 . The operator unpacks the tire belt set of the electric vehicle, takes out the tire belt 7 and hangs it on the hanging rod 11, and pushes the double-post trolley to the side of the knockdown equipment. In this embodiment, five tire belts 7 are initially hung on the hanging rod 11 .

The push-down device includes a base 21, a screw system installed on the base 21, and a push rod 22 that is drive-connected to the screw system. The lead screw 24 is arranged in the direction, and the lead screw 24 is threadedly connected with a slider, the slider is fixedly connected with the push rod 22 , and the end of the push rod 22 faces the five tire belts 7 hanging on the hanging rod 11 . When the servo motor 23 works, it drives the screw rod 24 to rotate in the forward or reverse direction, the screw rod 24 rotates and drives the slider to move linearly along the axis of the screw rod 24, and the slider drives the push rod 22 to the left or right in the horizontal direction. Moving, when the push rod 22 moves to the right, it can push the tire belt 7 hanging on the hanging rod 11 .

The conveyor belt is a roller conveyor belt. The conveyor belt is provided with a conveyor belt operation motor 32, a positioning block 41 and a lifting cylinder 42. A transmission mechanism is connected between the conveyor belt operation motor 32 and the roller 31. When the conveyor belt operation motor 32 works, it drives the rollers. The drum 31 is rotated. The top of the positioning block 41 faces the tapered end 12 of the hanging rod 11 , and the bottom of the positioning block 41 is fixedly connected to the piston rod of the lift cylinder 42 . When the piston rod drives the positioning block 41 to move upward to the preset position, the top surface of the positioning block 41 protrudes from the conveyor belt. When the piston rod drives the positioning block 41 to move down to the preset position, the top surface of the positioning block 41 is flush with the conveyor belt or below the conveyor belt. The two sides of the positioning block 41 are provided with baffles 6, and the two baffles 6 are symmetrically arranged on both sides of the conveyor belt. One of the baffles 6 is provided with a camera 5 facing the positioning block 41, and the camera 5 is electrically connected to a visual sensor. recognition system.

The specific embodiment of the present invention also provides a method for controlling a tire belt positioning and placing device. The method of the present invention is used to control the aforementioned device of the present invention, and the method includes the following steps:

First, the main control unit sends a control signal to the lift cylinder 42, and the lift cylinder 42 drives the positioning block 41 to move upward through its piston rod until the positioning block 41 protrudes from the conveyor belt;

Next, the main control unit sends a control signal to the servo motor 23, the servo motor 23 drives the screw rod 24 to rotate, the screw rod 24 drives the slider and then drives the push rod 22 to move linearly to the right, and the push rod 22 pushes the tire belt on the hanging rod 11. 7 Move to the right until the rightmost tire belt 7 is pushed down. The end of the hanging rod 11 is designed as a tapered end 12, which is conducive to the smooth sliding of the tire belt 7. When the tire belt 7 falls from the tapered end 12, the bottom of the tire belt 7 is blocked by the positioning block 41, so that the tire belt 7 is toppled, and the tire belt 7 is just horizontally clamped to the positioning block 41.

The separation between the horizontal tire belts 7 is thus eliminated. After the positioning block 41 is separated from the horizontal tire belt 7, the structure of the device of the present invention is shown in FIG. 2;

Then, the visual recognition system recognizes the grain direction of the horizontal tire belt 7 through the camera 5 . The reason why the baffles 6 are provided on both sides of the positioning block 41 are mainly for two purposes. One is to provide a lateral installation position for the camera 5, which is conducive to extracting the direction of the pattern of the tire belt 7 clamped on the positioning block 41; two It is to block the cluttered light in the background, so as to improve the accuracy of the direction recognition of the tire belt 7 lines;

Finally, the main control unit sends a control signal to the conveyor belt running motor 32 according to the texture direction identification result returned by the visual identification system, and the conveyor belt running motor 32 drives the conveyor belt to convey the horizontal tire belt 7 to a predetermined position. If the grain direction of the horizontal tire belt 7 is correct, it shall be transported to the assembly station of the tire belt and the wheel hub according to the normal procedure; The tire belt 7 is turned over by the turning device of the turning station, and then conveyed by the conveyor belt to the assembly station of the tire belt and the wheel hub.

Carrying out the cycle operation according to the above steps can ensure that all the tire belts 7 are horizontally placed in the middle of the conveyor belt according to the preset spacing, and are placed in the correct direction of the grain.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the technical principle of the present invention, several improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
