[0019] Such as Figure 1As shown in the figure, the first embodiment of the present utility model provides a flipping and conveying control system for the actions of a pre-treatment electrophoretic vehicle body on the basis of the prior art. It includes a horizontal walking assembly installed at both ends of the walking end beam. A walking motor 5 is provided on the horizontal walking assembly, and a walking motor encoder 7 is installed on the walking motor 5. A flipping shaft assembly, a reading dock 4, and a control box are respectively provided on the walking end beam. A flipping motor 6 is installed on the flipping shaft assembly, and a flipping motor encoder 8 is installed on the flipping motor 6. A controller 1, a walking motor frequency converter 2, and a flipping motor frequency converter 3 are respectively installed in the control box.

[0020] As described above, Figures 2-3 The controller 1 is electrically connected to the walking motor encoder 7, the flipping motor encoder 8, the reading dock 4, the walking motor frequency converter 2, and the flipping motor frequency converter 3 respectively.

[0021] Among them: The controller 1 outputs control information to the walking motor frequency converter 2 and the flipping motor frequency converter 3. The walking motor frequency converter 1 drives the walking motor 5 to perform horizontal movement, and the flipping motor frequency converter 3 drives the flipping motor 6 to perform flipping movement. The reading dock 4 reads and writes the track bar code value to the controller 1, and the controller 1 knows the real-time position of the flipping and conveying system. Its characteristics are: The walking motor encoder 7 is connected to the internal encoder card of the walking motor frequency converter through a cable, so that the encoder measures the speed information of the walking motor and outputs it to the walking motor frequency converter 2. The flipping motor encoder 8 is connected to the internal encoder card of the flipping motor frequency converter through a cable, so that the encoder measures the angle information of the flipping motor and outputs it to the flipping motor frequency converter 3. The reading dock 4 is connected to the controller 1 through a cable, so that the position information of the flipping and conveying system is output to the controller 1 in real time. The walking motor encoder 7 is an incremental encoder. The flipping motor encoder 8 is an absolute encoder. The flipping motor encoder 8 is a hollow shaft encoder. The controller 1 is a programmable logic controller. The interface type of the reading dock 4 is an RS485 interface.

[0022] This application realizes the motion control of the vehicle body on the pre-treatment electrophoretic production line. An encoder is installed on the shaft at the tail of the walking motor 5. The walking motor 5 drives the flipping and conveying mechanism to move horizontally, forward or backward. When the walking motor acts, the value of the encoder will change accordingly. The walking motor frequency converter 2 adjusts the output frequency according to the value of the encoder to realize the closed-loop control of the horizontal movement speed of the flipping and conveying mechanism.

[0023] An encoder is installed on the shaft at the tail of the flipping motor 6. The flipping motor 6 drives the flipping and conveying mechanism to perform flipping movement. When the flipping motor acts, the value of the encoder will change accordingly. The flipping motor frequency converter 3 controls the output of the frequency according to the value of the encoder to realize the closed-loop control of the flipping angle of the flipping and conveying mechanism.

[0024] A barcode reader 4 is installed on the flipping and conveying mechanism. When the flipping and conveying mechanism moves horizontally, the barcode reader 4 moves horizontally along with the flipping and conveying mechanism, reads and writes the barcode values on the track in real time, and feeds them back to the controller 1. The controller 1 monitors the real-time position of the flipping and conveying mechanism to achieve closed-loop control of the position of the flipping and conveying structure.

[0025] As Figure 2 shown, through the speed closed-loop control of the traveling motor 5, the angle closed-loop control of the flipping and conveying mechanism, and the position closed-loop control of the flipping and conveying mechanism, precise control of the body at a certain position and angle on the pre-treatment electrocoating production line is achieved. As Figure 2 shown, the body needs to be flipped 360 degrees in the tank. First, determine the flipping starting point, flipping ending point, traveling speed, and flipping angle at each position on the tank of the flipping and conveying mechanism. All the data information is preset to the controller 1. The controller 1 precisely controls the entire flipping process through the closed-loop control of speed, angle, and position. When the flipping and conveying mechanism runs to the flipping starting point, the barcode reader 4 feeds back the position information to the controller 1. The controller 1 sends a flipping instruction to the inverter 3 of the flipping motor. At the same time, the encoder 8 at the tail of the flipping motor feeds back the angle value to the inverter 3 of the flipping motor in real time and is transmitted to the controller 1 through the inverter 3 of the flipping motor. Ensure that during the forward flipping process of the flipping and conveying mechanism, the traveling position is precise and the speed is stable. The controller 1 controls the traveling speed through the encoder 7 of the traveling motor.

It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved.
