Description

Technical Field

[0001] This utility model relates to the field of spray painting production line technology, and in particular to an automatic loading and unloading and rapid workpiece positioning device for spray painting production lines. Background Technology

[0002] Spraying is a processing method that uses a spray gun to atomize paint and apply it to the surface of an object. During spraying, the product to be sprayed is fixed on a rotatable bracket, and then the bracket is locked on the production line. Through the movement of the production line and the continuous rotation of the rotatable bracket, the paint is evenly sprayed onto the surface of the product. It is widely used in the processing of protective layers for metal workpieces.

[0003] However, in the existing technology, most automatic loading and unloading and quick workpiece positioning devices for spray painting production lines use a conveyor chain to transport the workpiece holder to the required position, and then spray painting after the movement stops. This requires each holder to have a rotating structure, making the structure of the automatic loading and unloading and quick workpiece positioning device for spray painting production lines relatively cumbersome and inconvenient for accurate positioning. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a top plate and a servo motor. A drive gear is symmetrically rotatably connected to the bottom surface of the top plate. The output end of the servo motor rotatably passes through the top plate and is fixed to the top surface of the drive gear. A chain is meshed and sleeved on two drive gears. Several connecting plates are equidistantly fixed to the outer surface of the chain. A fixing plate is detachably fixed to the outer side of each connecting plate.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0022] like Figure 1-4 As shown, this utility model provides an automatic loading and unloading and rapid workpiece positioning device for a spray painting production line, including a top plate 1 and a servo motor 3. A drive gear 2 is symmetrically rotatably connected to the bottom surface of the top plate 1. The output end of the servo motor 3 rotates through the top plate 1 and is fixed to the top surface of the drive gear 2. A chain 4 is meshed and sleeved on the two drive gears 2. Several connecting plates 5 are equidistantly fixed to the outer surface of the chain 4. A fixing plate 6 is detachably fixed to the outside of the connecting plates 5. The fixing plate 6 is configured as an inverted L-shape. Each connecting plate 5 has symmetrically opened mounting... Each fixed plate 6 is fixedly connected to the connecting plate 5 by bolts. A rotating rod 10 is rotatably connected to the top of each fixed plate 6. A fixed frame 7 is fixed to the bottom surface of the rotating rod 10. A positioning block 11 is fixed to the top surface of the rotating rod 10. A support plate 12 is set above the positioning block 11. A rotating structure is set at the end of the support plate 12 near the positioning block 11. An electric push rod 17 is installed on the top surface of the top plate 1 of the support plate 12 away from the fixed plate 6. The output end of the electric push rod 17 is fixed to the top surface of the support plate 12. A positioning plate 16 is fixed to the bottom of one side of the support plate 12.

[0023] The specific setup and function of this embodiment are described below: A servo motor 13 is mounted on the top surface of the support plate 12. The output end of the servo motor 13 rotates through to the bottom surface of the support plate 12 and a gear 14 is fixed thereon. A gear 15 is meshed with the side of the gear 14. The top surface of the gear 15 is rotatably connected to the bottom surface of the support plate 12 through a bearing. A connecting groove 19 that mates with the positioning block 11 is opened on the bottom surface of the gear 15. A limit slide rod 18 is slidably sleeved inside the support plate 12 between the servo motor 13 and the electric push rod 17. The bottom surface of the limit slide rod 18 is fixed to the top surface of the top plate 1. After the workpiece moves to the bottom of the support plate 12 and the positioning block 11 abuts against the positioning plate 16, the gear 15 moves down and sleeves itself on the positioning block 11, driving the workpiece to rotate. There is no need to set a drive structure on the top surface of each fixed plate 6, and it will not affect the normal loading and unloading of the workpiece. Example

[0024] like Figure 1-4 As shown, a fixing plate 8 is slidably sleeved inside the fixing frame 7. The fixing frame 7 is set as an inverted U-shape. The top surface of the fixing plate 8 is a rectangle that fits against the top surface inside the fixing frame 7. A fixing screw 9 is rotatably connected to one side of the fixing plate 8 through a bearing. The fixing screw 9 is threadedly sleeved inside one end of the fixing frame 7. A threaded hole that mates with the fixing screw 9 is opened at one end of the fixing frame 7.

[0025] The overall effect of this embodiment is that the workpiece is clamped by the cooperation of the fixed frame 7, the fixed clamping plate 8 and the fixed screw 9, making it easier to fix and disassemble the workpiece when loading and unloading. During the spraying process, the sprayed workpiece can be removed and the workpiece to be sprayed can be fixed inside the fixed frame 7.

[0026] The usage and working principle of this device are as follows: When an automatic loading / unloading and rapid workpiece positioning device is required, the workpiece is placed between the fixed clamping plate 8 and the fixed frame 7. Tightening the fixing screw 9 moves the fixed clamping plate 8 to tighten the workpiece. Servo motor 3 drives the drive gear 2 to rotate, which in turn moves the chain 4, thus moving the workpiece for loading. When the workpiece moves to below the support plate 12 and the positioning block 11 abuts against the side of the positioning plate 16, the positioning block 11 aligns with the connecting groove 19. The electric push rod 17 moves, causing the support plate 12 to move downwards. The downward movement of the support plate 12 causes the gear 15 to move downwards and fit onto the top surface of the positioning block 11. At this time, servo motor 3 stops running, and servo motor 13 begins to move. The first gear 14 rotates, which in turn drives the second gear 15 to rotate, thereby rotating the workpiece to achieve full-area spraying. After spraying is completed, the electric push rod 17 moves the second gear 15 and the positioning plate 16 to the top of the positioning block 11. The servo motor 3 then moves the workpiece to continue moving. The electric push rod 17 then moves the support plate 12 down, moving the positioning plate 16 to the horizontal plane on the side of the positioning block 11. The positioning block 11 is then moved to the side of the positioning plate 16. At this time, the second gear 15 is located above the positioning block 11. When the servo motor 3 stops running and the next workpiece is positioned for spraying, the fixing screw 9 is turned to remove the sprayed workpiece and fix the workpiece to be sprayed inside the fixing frame 7.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
