[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-5 An electrophoretic coating spraying device includes a spray tank 1, a lifting assembly at one end of the spray tank 1, a support rod 17 mounted on the lifting assembly, a support frame 13 connected to one end of the support rod 17, a support net 14 at the bottom end of the support frame 13, a conical sedimentation hopper 8 at one side of the bottom end of the spray tank 1, an insert plate 12 slidably inserted into the inner wall of the conical sedimentation hopper 8, a first electric push rod 11 fixed to the inner wall of the spray tank 1, the bottom end of the first electric push rod 11 connected to the top end of the insert plate 12, a spraying assembly mounted on one side of the spray tank 1, a PLC controller 23 (model: FX3U-32MT / ES-A) fixed to the outer wall of one side of the spray tank 1, and an ultrasonic cleaning assembly mounted at the bottom end of the spray tank 1.

[0022] The lifting assembly includes a U-shaped rod 22 fixed to one side of the inner wall at the bottom of the spray tank 1. An I-shaped slider 16 is slidably engaged on the inner side of the U-shaped rod 22. A U-shaped plate 3 is fixed to one side of the top of the outer wall of the spray tank 1. A second electric push rod 18 is fixed to the lower end of the horizontal section of the U-shaped plate 3. The lower end of the second electric push rod 18 is connected to the top of the I-shaped slider 16.

[0023] A liquid level sensor 2 (model: LMK 351) is installed on one side of the lower end face of the horizontal section of the U-shaped plate 3. Both the liquid level sensor 2 and the second electric push rod 18 are electrically connected to the PLC controller 23.

[0024] The spray assembly includes a spray pump 6 fixed to one side of the outer wall of the spray tank 1. The pump end of the spray pump 6 is connected to the water supply pipe 5. The spray pipe 4 connected to the outlet end of the spray pump 6 extends to the upper part of the interior of the spray tank 1. Spray heads 9 are installed at equal intervals on the spray pipe 4 above the support frame 13.

[0025] A flow guide ramp 15 is provided at the bottom of the inner wall of the spray tank 1 and on one side of the conical sedimentation hopper 8.

[0026] The ultrasonic cleaning assembly includes a mounting plate 19 fixed to one side of the lower end face of the spray tank 1, an ultrasonic generator 21 mounted on the mounting plate 19, and a transducer 20 mounted in the middle of the lower end face of the spray tank 1.

[0027] Two support legs 7 are symmetrically fixed at the bottom of the spray tank 1, and a drain valve 10 is installed on one side of the bottom of the spray tank 1.

[0028] The second electric push rod 18 is started by the PLC controller 23, which drives the I-shaped slider 16 to slide upward along the U-shaped rod 22, thereby raising the support frame 13 to the top of the spray tank 1 and placing the workpiece to be cleaned evenly on the support net 14 of the support frame 13. The cleaning parameters are set by the PLC controller 23, and the cleaning program is started. The PLC controller 23 controls the extension of the second electric push rod 18, which drives the support frame 13 to descend into the cleaning area in the spray tank 1. The spray pump 6 is started, and the spray liquid is drawn into the spray pipe 4 through the water supply pipe 5. It is then sprayed evenly onto the surface of the workpiece at high pressure through the spray head 9 to rinse and clean the oxide scale, rust, grease and other dirt on the surface of the workpiece. After the workpiece is submerged in the liquid, the spray pump 6 is turned off, and the ultrasonic generator 21 is started. The high-frequency signal generated by the generator is converted into ultrasonic vibration by the transducer 20 and transmitted to the spray liquid. The ultrasonic cavitation effect is used to peel off and clean the stubborn dirt attached to the surface of the workpiece, thereby improving the cleaning effect. During the cleaning process, the liquid level sensor 2 continuously monitors the liquid level. If the liquid level is lower than the preset value, the PLC controller 23 automatically controls the water supply pipe 5 to replenish the spray liquid and maintain the liquid level stability. After the ultrasonic cleaning is completed, the second electric push rod 18 is started by the PLC controller 23 to drive the I-shaped slider 16 to slide upward along the U-shaped rod 22, so that the carrier frame 13 carries the workpiece away from the cleaning liquid. The spray pump 6 is started again, and the residual impurities attached to the surface of the workpiece are washed away by the spray head 9 to ensure the cleanliness of the workpiece. During the cleaning process, dirt particles sink under gravity and slide along the guide ramp 15 into the conical sedimentation hopper 8 for concentrated deposition. When the cleaning operation is completed or the dirt in the sedimentation hopper accumulates to a certain amount, the drain valve 10 is opened to discharge the wastewater for recycling. Then, the PLC controller 23 controls the first electric push rod 11 to retract, causing the insert plate 12 to slide upward and open the bottom channel of the conical sedimentation hopper 8. The deposited dirt is discharged under gravity. A collection container can be placed below the sedimentation hopper to collect the dirt. After the dirt is discharged, the first electric push rod 11 is extended, causing the insert plate 12 to reset and close the channel.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
