Description

Technical Field

[0001] The utility model relates to the technical field of automobile painting production line equipment, in particular to a body electrophoresis painting turnover mechanism. Background Technique

[0002] As is well known, the electrophoresis process is divided into anodic electrophoresis and cathodic electrophoresis. If the coating particles are negatively charged and the workpiece is the anode, the coating particles are deposited on the workpiece under the action of the electric field force to form a film, which is called anodic electrophoresis. During the production of the vehicle body, a turnover mechanism is required to fix the vehicle body and perform turnover electrophoresis in the electrophoresis tank.

[0003] In real life, the common body electrophoresis painting turnover mechanism can only drive the body to turn back and forth and move in the electrophoresis liquid. When the body is moving, the electrophoresis effect on the front and rear parts of the body is the best, that is, the air in the box-shaped structure arranged longitudinally in the front and rear is discharged, and a water flow that disperses to both sides is formed at the front of the body. This water flow reduces the flow of the electrophoresis liquid on both sides of the body to the left and right sides of the body, thus making it inconvenient to discharge the air in the box-shaped structure arranged horizontally on the body. Therefore, the practicability is not very good and there is still room for improvement. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-9 , a body electrophoresis coating flipping mechanism of the present utility model includes a support plate 1 and a top bracket 2. Several positioning lock pins 11 are arranged on the upper part of the top bracket 2, and pneumatic lock hooks capable of locking the vehicle body are arranged on each of the several positioning lock pins 11. The vehicle body to be electrophoresed is locked by the several positioning lock pins 11. A rotating rod is rotatably connected to the middle of the support plate 1 through a rotating shaft, and a moving frame 12 is rotatably connected to the rotating rod through a bearing. The production equipment for body electrophoresis drives the moving frame 12 to move beside the electrophoresis tank. A connecting rod is rotatably connected to the lower part of the support plate 1 through a bearing, and a motor 3 is installed on the right part of the connecting rod. When the motor 3 is started, the motor 3 rotates, drives the connecting rod to rotate, and drives the support plate 1, the top bracket 2 and the vehicle body to rotate, and enters the electrophoresis tank for electrophoresis, which is convenient for discharging the air in the longitudinally arranged box-shaped structure.

[0028] A bottom bracket 4 is provided on the left part of the connecting rod. Several mounting grooves 5 are provided around the bottom bracket 4. Several adjusting devices are provided on the lower part of the top bracket 2 for adjusting the top bracket 2 to swing at different angles, so as to drive the vehicle body on the top bracket 2 to shake in the electrophoresis tank, and swing in a direction perpendicular to the moving direction of the vehicle body driven by the moving frame 12, so as to discharge the electrophoresis liquid and the air in the horizontally arranged box-shaped structure inside the vehicle body. The lower parts of several adjusting devices are all installed in the corresponding mounting grooves 5. Several adjusting devices all include waterproof hydraulic cylinders 6. First balls 7 are provided on the upper parts of several waterproof hydraulic cylinders 6. Fixed rods 8 are connected to the upper parts of several first balls 7 in a rolling manner. Second balls 9 are connected to the upper parts of several fixed rods 8 in a rolling manner. Extension rods 10 are provided on the upper parts of several second balls 9. The upper parts of several extension rods 10 are fixedly connected to the lower part of the top bracket 2. The staff starts the waterproof hydraulic cylinders 6 on the left and right sides successively. Several waterproof hydraulic cylinders 6 extend, driving the fixed rods 8 to extend out of the mounting grooves 5, and then continue to extend and contract reciprocally, so that the fixed rods 8 move up and down outside the mounting grooves 5. At this time, when the fixed rods 8 are moving, during the vibration, both the first balls 7 and the second balls 9 are arranged in a rolling manner with the fixed rods 8, so that the fixed rods 8 and the waterproof hydraulic cylinders 6 are in a swinging state. Then the top bracket 2 is arranged in a swinging manner through the second balls 9 and the fixed rods 8, driving the vehicle body to swing at multiple angles in the electrophoresis tank and collide with the electrophoresis liquid in the electrophoresis tank at multiple angles. Intervals are provided between several fixed rods 8 and the inner walls of the mounting grooves 5, and anti-corrosion coatings are applied to all of them. When the waterproof hydraulic cylinders 6 on the left and right sides are started successively, they drive the fixed rods 8 to slide out of the mounting grooves 5 respectively. The intervals therebetween can prevent the fixed rods 8 from rubbing against the mounting grooves 5, and at the same time the anti-corrosion coatings improve the anti-corrosion effect.

[0029] In summary, when using this vehicle body electrophoresis coating flipping mechanism, the staff installs the vehicle body on the positioning lock pin 11 of the top bracket 2, and then drives the moving frame 12 to move beside the electrophoresis tank through the production equipment of vehicle body electrophoresis. The motor 3 is started to drive the bottom bracket 4, the top bracket 2 and the vehicle body to rotate, and the vehicle body enters the electrophoresis liquid in the electrophoresis tank. The left waterproof hydraulic cylinder 6 is started. The left waterproof hydraulic cylinder 6 extends first, driving the left part of the top bracket 2 and the vehicle body to move downward. After moving a certain distance, the right waterproof hydraulic cylinder 6 is started. The right waterproof hydraulic cylinder 6 extends first, driving the right part of the top bracket 2 and the vehicle body to move downward. At this time, the vehicle body is in an inclined state. Then the left waterproof hydraulic cylinder 6 starts to contract after extending to the maximum state, driving the vehicle body at this part to move upward. The right waterproof hydraulic cylinder 6 starts to contract after extending to the maximum state, driving the vehicle body at this part to move upward. Work in this way repeatedly, so that the vehicle body shakes left and right and up and down in the electrophoresis liquid and makes full contact with the electrophoresis liquid.
