Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision casting equipment, specifically to a speed change device for a robot shell-making dip-coating tank. Background Technology
[0002] Currently, the main application of robots in the precision casting industry is to replace manual labor in the process of dipping and shelling large batches of products. The addition of robots makes the dipping and sanding process more efficient, the consistency of products better, the production control simpler, and the product quality more stable.
[0003] While existing robotic slurry-coating tanks can achieve the slurry-coating function, the stirring paddle inside the tank rotates at a constant speed. When the casting is placed into the slurry-coating tank, the slurry moves too quickly due to the excessively fast stirring paddle speed, which affects the uniformity of the slurry adhesion to the casting and is detrimental to the slurry-coating quality of the casting. Further improvements are needed.
[0004] Therefore, it is necessary to invent a speed-changing device for a robotic shell-making and paste-dipping bucket. Utility Model Content

A first servo motor is vertically fixed to the top of the inner wall of the motor housing. The first servo motor is electrically connected to the controller, and a rotary table is fixed to the top of the output shaft of the first servo motor.
[0008] Preferably, the rotary table has several cantilever arms fixed in a circular array on its side end. Each cantilever arm has a second servo motor fixed at the end away from the rotary table. Each second servo motor is electrically connected to a controller, and each output shaft of the second servo motor has a rotating arm fixed to it.
[0009] Preferably, each end of the rotating arm away from the cantilever is fixed with a hanging rod, and each hanging rod is on which a casting is hung.
[0010] Preferably, the variable speed stirring assembly includes a through-beam photoelectric sensor, which is fixed on both sides of the top of the slurry tank and electrically connected to the controller.
[0011] Preferably, a variable frequency motor is fixed at the center of the bottom of the slurry tank, the variable frequency motor is electrically connected to the controller, the top end of the output shaft of the variable frequency motor extends into the slurry tank, and a stirring paddle is fixed at the top end of the output shaft of the variable frequency motor.
[0012] The beneficial effects of this utility model are: by using the base plate, control console, controller, slurry tank, casting part loading and unloading assembly and speed-changing stirring assembly in combination, when the casting part is loaded into the slurry tank, the stirring paddle in the slurry tank rotates slowly at a variable speed, which effectively reduces the movement speed of the slurry in the slurry tank, so that the slurry can better adhere to the surface of the casting part, which is beneficial to the slurry coating quality of the casting part and is suitable for widespread use.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0019] Please refer to the appendix. Figures 1-4 The present invention provides a robot shell making slurry dipping bucket speed change device, including a base plate 1, a control console 2 fixed on one side of the top of the base plate 1, a controller 3 fixed at the front end of the control console 2, a slurry dipping bucket 4 fixed on the other side of the top of the base plate 1 for stirring slurry, a casting part loading and unloading assembly fixed on the top of the control console 2, a speed change stirring assembly fixed on the slurry dipping bucket 4, and both the casting part loading and unloading assembly and the speed change stirring assembly are electrically connected to the controller 3;
[0020] The casting loading and unloading assembly includes a motor housing 5, the bottom of which is fixed to the top of the control console 2. A first servo motor 6 is vertically fixed to the top of the inner wall of the motor housing 5. The first servo motor 6 is electrically connected to the controller 3. A rotary table 7 is fixed to the top of the output shaft of the first servo motor 6. Several cantilever arms 8 are fixed in a circular array on the side of the rotary table 7. A second servo motor 9 is fixed to the end of each cantilever arm 8 away from the rotary table 7. The second servo motor 9 is electrically connected to the controller 3. A rotating arm 10 is fixed to the output shaft of each second servo motor 9. A hanging rod 11 is fixed to the end of each rotating arm 10 away from the cantilever arm 8. A casting 12 is hung on each hanging rod 11. Specifically, when the second servo motor 9 is running, it can drive the corresponding hanging rod 11 to swing up and down, thereby controlling the casting 12 to move down into the slurry tank 4 or move up out of the slurry tank 4. When the first servo motor 6 is running, it can drive the corresponding casting to move to the top of the slurry tank 4 or rotate out of the top of the slurry tank 4, thereby controlling the castings at multiple workstations to perform slurry dipping operations in sequence.
[0021] The variable-speed stirring assembly includes a through-beam photoelectric sensor 13. It should be noted that the through-beam photoelectric sensor is a device that detects objects by changing the light path. Its core components include a light emitter and a spatially separated receiver. When an object blocks the light emitted by the emitter, causing an interruption in the light path, the receiver analyzes the signal and triggers a switch state change, thereby achieving target detection. The through-beam photoelectric sensor 13 is fixed on both sides of the top of the slurry tank 4 and is electrically connected to the controller 3. A variable-frequency motor 14 is fixed at the center of the bottom of the slurry tank 4 and is electrically connected to the controller 3. The top of the output shaft of the variable-frequency motor 14 extends into the slurry tank 4, and a stirring paddle 15 is fixed to the top of the output shaft. It should be noted that the output shaft of the variable-frequency motor 14 is sealed to the bottom of the slurry tank 4 via a rotary dynamic sealing connector. Specifically, when the second servo motor 9 controls the corresponding casting 12 to move down into the slurry tank 4, it will block the through-beam photoelectric sensor 13, thereby sending a signal to the controller 3. After receiving the signal, the controller 3 controls the variable frequency motor 14 to reduce its speed, which in turn drives the stirring paddle 15 to rotate slowly. That is, when the casting is fed into the slurry tank 4, the stirring paddle 15 in the slurry tank 4 rotates slowly at a variable speed, effectively reducing the movement speed of the slurry in the slurry tank 4, so that the slurry can better adhere to the surface of the casting, which is beneficial to the slurry coating quality of the casting. When the second servo motor 9 reverses its operation and controls the corresponding casting 12 to move up out of the slurry tank 4, it no longer blocks the through-beam photoelectric sensor 13, thereby allowing the variable frequency motor 14 to resume its speed, which drives the stirring paddle 15 to rotate quickly in the slurry tank 4 to stir the slurry.
[0022] The usage process of this utility model is as follows: The operator first hangs the casting to be dipped in slurry on the corresponding hanging rod 11 through the bracket (not shown in the figure). Then, by running the first servo motor 6, the corresponding casting is controlled to move sequentially above the slurry tank 4. Then, by running the second servo motor 9, the corresponding casting is controlled to rotate sequentially and move down into the slurry tank 4. When the second servo motor 9 controls the corresponding casting 12 to move down into the slurry tank 4, it will block the through-beam photoelectric sensor 13, thereby sending a signal to the controller 3. After receiving the signal, the controller 3 controls the variable frequency motor 14 to reduce the speed, which can drive the stirring paddle 15 to rotate slowly. That is, when the casting is fed into the slurry tank 4, the stirring paddle 15 in the slurry tank 4 rotates slowly at a variable speed, effectively reducing the movement speed of the slurry in the slurry tank 4, so that the slurry can better adhere to the surface of the casting, which is beneficial to the slurry quality of the casting.
[0023] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
