[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0017] like Figures 1 to 4 As shown, this utility model discloses an automatic electrophoretic coating equipment for workpieces, including: an electrophoretic tank 1, which is a horizontally arranged cuboid electrophoretic tank 1; a lifting mechanism 22, used to drive the suspension mechanism 2 to lift; and a moving mechanism 21, used to drive the lifting mechanism 22 to move, so as to facilitate loading and unloading.

[0018] The moving mechanism 21 is a common type of moving mechanism 21. For example, the moving mechanism 21 includes: a mounting beam 3 fixedly installed on the roof, a slide rail 4 fixedly installed on the side wall of the mounting beam 3, and a second rack 24. The second rack 24 is located above the slide rail 4, and the teeth of the second rack 24 face downward. Rollers 5 are slidably connected to the sides of the slide rail 4 and the second rack 24 that are far apart from each other. The rollers 5 are rotatably installed on the mounting plate 6. A second gear 25 is also installed on the mounting plate 6. The second gear 25 is meshed with the second rack 24. The second gear 25 is coaxially connected to a moving motor 23. The moving motor 23 drives the second gear 25 to rotate, thereby causing the second gear 25 to slide along the second rack 24. The movement is achieved by multiple rollers 5 sliding along the side of the second rack 24 that is far apart from the slide rail 4.

[0019] The lifting mechanism 22 is a common type of lifting mechanism 22. For example, the lifting mechanism 22 includes: a lifting motor 7 fixedly mounted on a motor mounting plate 6, with a reducer 8 connected to its output end; drive shafts 9 symmetrically connected to both ends of the reducer 8; a connecting seat 10 connected to the drive shaft 9, which is fixedly mounted at the bottom of the lifting mechanism 22; a bearing 11 installed inside the connecting seat 10, and the drive shaft 9 is rotatably connected to the bearing 11; winding rollers 12 are fixedly connected to the ends of the two drive shafts 9 that are far apart from each other, and steel wire ropes 13 are wound on the winding rollers 12; the bottom of the steel wire ropes 13 is connected to the suspension mechanism 2; when the lifting motor 7 is started, the reducer 8 slows down the speed, drives the drive shafts 9 to rotate, and then drives the winding rollers 12 to rotate, thereby releasing the steel wire ropes 13 during rotation to move the suspension mechanism 2 downward, or tightening the steel wire ropes 13 to move the suspension mechanism 2 upward, thus achieving lifting.

[0020] The lifting end of the lifting mechanism 22 (i.e., the bottom end of the wire rope 13) is connected to a connecting rod 14; the connecting rod 14 is rotatably connected to a suspension mechanism 2; the suspension mechanism 2 includes: a mounting disc 15 rotatably connected to the bottom of the connecting rod 14, the mounting disc 15 being cylindrical; the mounting disc 15 is symmetrically arranged in two pieces along the width direction of the electrophoresis tank 1; mounting rods 16 are respectively installed on the side of the two mounting discs 15 that are close to each other, each mounting disc 15 is equipped with at least one mounting rod 16, and the mounting rods 16 are arranged opposite to each other; a suspension rod 17 is connected between the two opposite mounting rods 16, and the suspension rod 17 is provided with at least one... Two mounting discs 15 are respectively mounted on opposite sides. The connecting shafts pass through the connecting rod 14, and the other end of the connecting shaft is coaxially fixedly connected to the first gear 18. The connecting rod 14 is located between the mounting disc 15 and the first gear 18. A first rack 19 is mounted on the inner wall of the electrophoresis tank 1. The first rack 19 is symmetrically mounted vertically in the middle of the inner wall of the electrophoresis tank 1, and two racks 19 are symmetrically arranged along the width direction of the electrophoresis tank 1. The first gear 18 is meshed with the first rack 19.

[0021] When the lifting mechanism 22 drives the suspension mechanism 2 to descend as a whole, the first gear 18 meshes with the first rack 19, forcing the first gear 18 to rotate during the descent, which in turn causes the mounting disc 15 to rotate, thereby driving the suspension rod 17 to rotate. The suspension rod 17 is cuboid in shape (with a rectangular cross-section). When the suspension rod 17 rotates, the square ring workpiece placed on the suspension rod 17 will switch its contact position with the suspension rod 17 as the suspension rod 17 rotates, so that the part that was initially in contact with the suspension rod 17 no longer continues to be in contact, thus allowing the part to be fully electrophoresed.

[0022] Preferably, a guide block 20 is also installed on the inner wall of the electrophoresis tank 1. Two guide blocks 20 are symmetrically arranged on the inner wall of the same side of the electrophoresis tank 1 along the length of the electrophoresis tank 1. The two guide blocks 20 gradually converge from top to bottom to form an inverted V-shaped guide groove with the opening facing upward, which is used to guide the connecting rod 14. On the side wall of the opposite side of the electrophoresis tank 1, two guide blocks 20 with the same structure are respectively arranged at corresponding positions. The two guide blocks 20 are arranged in a mirror symmetrical manner. When the connecting rod 14 enters the inverted V-shaped guide groove, it first completes the initial positioning through the inverted V-shaped guide groove, and then gradually limits the movement during the downward movement so that the first gear 18 and the first rack 19 can make stable contact.

[0023] Preferably, the mounting rod 16 is detachably connected to the suspension rod 17, which facilitates the removal of the square-ring workpiece suspended on the suspension rod 17.

[0024] Working principle: When electrophoretic coating is required on a square ring workpiece, the square ring workpiece is suspended on the suspension rod 17 of the suspension mechanism 2. Then, the suspension mechanism 2 is moved above the electrophoresis tank 1 by the moving component. Then, the suspension mechanism 2 is lowered into the electrophoresis tank 1 by the lifting mechanism 22. During the descent, the guide block 20 limits the connecting rod 14, so that the connecting rod 14 drives the mounting disc 15 and the first gear 18 to move towards the center of the guide block 20. Then, the first gear 18 meshes with the first rack 19, so that the first gear 18 rotates during the downward movement, thereby causing the mounting disc 15 to rotate, which in turn causes the suspension rod 17 to rotate. This causes the square ring workpiece suspended on the suspension rod 17 to change its contact position with the suspension rod 17, thus achieving full electrophoresis.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings.
