[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, an automatic feeding device for electrophoresis of metal products includes a base 1. A top platform 2 is fixedly connected to the upper side of the base 1 near the edge via a column. Two centrally symmetrically distributed first conveying mechanisms 3 are movably installed on the upper side of the base 1 near the left and right sides. An attitude detection mechanism 4 is movably installed on the upper side of the first conveying mechanism 3 located on the left. A second conveying mechanism 5 is movably installed on the lower side of the top platform 2 at a position slightly behind the center. Several evenly distributed fixing mechanisms 6 are rotatably connected to the outer side of the second conveying mechanism 5. An electrophoresis pool 7 is fixedly connected to the upper center of the base 1.

[0027] The fixing mechanism 6 includes a first telescopic rod 61, a lifting plate 62 is fixedly connected to the lower side of the first telescopic rod 61, and four fixing components 63 distributed front and rear are fixedly connected to the upper side of the lifting plate 62. The fixing components 63 include a second telescopic rod 631, the lower side of the second telescopic rod 631 is fixedly connected to the upper side of the lifting plate 62, and a guide frame 632 is fixedly connected to the upper side of the second telescopic rod 631. Two clamping rods 633 are rotatably connected to the uprights on the front and rear sides of the upper side of the lifting plate 62.

[0028] It should be noted that the first conveying mechanism 3 on the left is used to convey the workpiece, and the posture detection mechanism 4 is used to detect the placement posture of the conveyed workpiece. The first conveying mechanism 3 on the right is used to unload the workpiece, and the second conveying mechanism 5 is used to circulate the fixed mechanism 6. The fixed mechanism 6 is evenly arranged on the second conveying mechanism 5, and the conveying line of the second conveying mechanism 5 is circular, allowing the fixed mechanism 6 to move cyclically. The first telescopic rod 61 is an electric push rod that can drive the lifting plate 62 to move up and down. When the fixed mechanism 6 moves to the left, it performs a clamping operation on the workpiece. Electrophoresis is performed in pool 7, and unloading is performed when it is moved to the right. By extending the length of electrophoresis pool 7, the electrophoresis time can be increased. The power supply equipment on the fixing mechanism 6 provides power by means of brushes set on the second conveying mechanism 5. The lower side of the lifting plate 62 contacts the workpiece by means of contacts. The two clamping rods 633 are arranged in an X shape and rotate relative to each other. The second telescopic rod 631 is an electric push rod that drives the guide frame 632 to move up and down, so that the upper sides of the two clamping rods 633 move closer to each other, thereby driving the bottoms of the two clamping rods 633 to move closer to each other.

[0029] like Figure 5 As shown, the lower side of the first telescopic rod 61 is fixedly connected to two limiting strips 635 distributed front and back, and the outer side of the limiting strips 635 is slidably connected to two clamping blocks 634 distributed left and right. The lower side of the clamping rod 633 is slidably connected to the inner front and back sides of the clamping blocks 634.

[0030] It should be noted that when the bottoms of the two clamping rods 633 approach each other, they cause the two clamping blocks 634 to approach each other, thereby clamping the workpiece with the clamping blocks 634. This avoids the problem of the bottom of the clamping rods 633 not being able to fit the side of the workpiece when clamping directly with the bottom of the clamping rods 633. The side of the two clamping blocks 634 that approaches each other has a convex structure to minimize the contact area between the clamping blocks 634 and the workpiece, and to avoid damage to the uncured paint film when alternating clamping.

[0031] like Figure 4 As shown, guide wheels 636 are rotatably connected to the upper side of both clamping rods 633.

[0032] It should be noted that the guide wheel 636 is used to reduce the friction between the clamping rod 633 and the guide frame 632, thereby improving the service life of the components.

[0033] like Figure 5 As shown, a torsion spring is provided between the two clamping rods 633.

[0034] It should be noted that the torsion spring is used to drive the clamping rod 633, so that when the guide frame 632 moves upward, the bottom of the clamping rod 633 automatically separates.

[0035] like Figure 2 , Figure 3 As shown, a rotating seat 65 is rotatably connected to the outer side of the second conveying mechanism 5, and a motor 64 is fixedly connected to the lower side of the rotating seat 65. The upper side of the first telescopic rod 61 is fixedly connected to the output end of the motor 64.

[0036] It should be noted that, relying on the attitude detection mechanism 4 to detect the attitude of the conveyed workpiece, the motor 64 drives the first telescopic rod 61 to rotate, so that the fixing component 63 can clamp the workpiece in a suitable state. Then, the motor 64 drives the first telescopic rod 61 to reset. The attitude detection mechanism 4 and the motor 64 are linked together by a remote signal transmission device.

[0037] like Figure 3 As shown, two third telescopic rods 66, distributed on the left and right sides, are fixedly connected to the side of the rotating seat 65 away from the second conveying mechanism 5.

[0038] It should be noted that the third telescopic rod 66 is an electric push rod that can control its own length so that the two third telescopic rods 66 are close to the front side of the second conveying mechanism 5. This prevents the rotating seat 65 from rotating arbitrarily on the second conveying mechanism 5 when the fixing mechanism 6 is performing clamping, electrophoresis, and unloading operations. After the workpiece is electrophoresed, the third telescopic rod 66 on one side can quickly and frequently extend and retract, causing the fixing mechanism 6 to vibrate, thereby shaking off the water droplets on the workpiece.

[0039] like Figure 3 As shown, rubber pads are fixedly connected to the side of the two third telescopic rods 66 near the second conveying mechanism 5.

[0040] It should be noted that the rubber pad is used to prevent rigid contact between the third telescopic rod 66 and the second conveying mechanism 5, which could cause the component to be squeezed and deformed.

[0041] The working principle of this utility model is as follows: First, the lower side of the lifting plate 62 contacts the workpiece via contact points. The two clamping rods 633 are arranged in an X-shape and rotate relative to each other. The second telescopic rod 631 is an electric push rod that drives the guide frame 632 to move up and down, causing the upper sides of the two clamping rods 633 to move closer together. This, in turn, causes the bottom sides of the two clamping rods 633 to move closer together. When the bottom sides of the two clamping rods 633 move closer together, they cause the two clamping blocks 634 to move closer together, thereby clamping the workpiece with the clamping blocks 634. This avoids directly using the bottom of the clamping rods 633. The problem of the clamping rod 633 not being able to fit properly against the side of the workpiece due to partial clamping is addressed by setting multiple fixing components 63. In the initial state, two fixing components 63 are used to clamp the workpiece. After the electrophoresis operation, the other two fixing components 63 clamp the workpiece, and the two initially clamping fixing components 63 release their grip on the workpiece to prevent part of the workpiece from being covered by the clamping block 634, which would lead to poor electrophoresis results. Finally, the first conveying mechanism 3 on the left is used to convey the workpiece, and the attitude detection mechanism 4 is used to detect the placement attitude of the conveyed workpiece. The second and third conveying mechanisms on the right are also used to convey the workpiece. A first conveyor mechanism 3 is used to unload workpieces, and a second conveyor mechanism 5 is used to circulate and transport workpieces to a fixed mechanism 6. A first telescopic rod 61 is an electric push rod that can move a lifting plate 62 up and down. When the fixed mechanism 6 moves to the left, it performs a workpiece clamping operation; when it moves to the electrophoresis pool 7, it performs an electrophoresis operation; and when it moves to the right, it performs an unloading operation. By extending the length of the electrophoresis pool 7, the electrophoresis time is increased. The power supply equipment on the fixed mechanism 6 provides power through brushes installed on the second conveyor mechanism 5. The lower side of the lifting plate 62 contacts the workpiece via contact points. The three telescopic rods 66 are electric push rods that can control their length so that the two third telescopic rods 66 are close to the front of the second conveying mechanism 5. This prevents the rotating seat 65 from rotating arbitrarily on the second conveying mechanism 5 when the fixing mechanism 6 is performing clamping, electrophoresis, and unloading operations. The posture of the conveyed workpiece is detected by the posture detection mechanism 4, and then the motor 64 drives the first telescopic rod 61 to rotate, so that the fixing component 63 clamps the workpiece in a suitable state. The workpiece loading, electrophoresis, and unloading operations are completed by the conveying of the second conveying mechanism 5, which improves the workpiece processing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
