Description

Technical Field

[0001] This utility model relates to the field of stepper motor driver manufacturing technology, and in particular to a spraying device for a stepper motor driver circuit board. Background Technology

[0002] Circuit boards provide the electrical connections for electronic components. To prevent copper oxidation and ensure good solderability of components, circuit boards require surface coating during the manufacturing process.

[0003] Commonly used spraying equipment is usually carried out in an open environment, which can easily cause paint to splash, affecting the working environment. It is also inconvenient to quickly adjust and position circuit boards of different sizes. Furthermore, it is not convenient to rotate the equipment during the spraying process, which can easily lead to uneven spraying. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a spraying device for stepper motor driver circuit boards, thereby solving the problems mentioned in the background art.

[0005] A spraying device for a stepper motor driver circuit board includes a spraying chamber, a drive mechanism and a spraying mechanism mounted on the spraying chamber. The drive mechanism includes an adjusting screw, a lifting shaft, a first drive wheel, a motor, a second drive wheel, a first limiting part, a second limiting part, a connecting rod and a rotating seat. The adjusting screw is rotatably mounted on a bracket fixed at the top of the spraying chamber. The lifting shaft is rotatably mounted on the bottom of the adjusting screw and extends downward into the interior of the spraying chamber. The drive wheel is fitted onto the outer wall of the lifting shaft and rotatably mounted on the spraying chamber. The motor is mounted on the bracket. The second drive wheel is fixedly mounted at the output end of the motor and meshes with the first drive wheel. The first limiting part is fixed to the bottom of the lifting shaft. The second limiting part is rotatably mounted on the bottom surface inside the spraying chamber via the rotating seat. The connecting rod passes through the ends of the first and second limiting parts.

[0006] By adopting the above technical solution, this device can quickly place and automatically spray stepper motor driver circuit boards of different sizes, while avoiding the paint from affecting the external environment during the spraying process.

[0007] Processing environment.

[0008] The spraying mechanism includes a water pipe and a nozzle. The water pipe is fixedly installed at the expansion part of the spraying chamber. The nozzles are multiple nozzles installed at equal intervals on the water pipe. The water pipe is also connected to a connector that extends to the outside of the spraying chamber.

[0009] The circuit board is coated using the above-mentioned technical solution.

[0010] A groove is provided on one side of the lifting shaft, and the outline of the connecting hole in the middle of the drive wheel is adapted to the outline of the outer wall of the lifting shaft.

[0011] By adopting the above technical solution, adjustments can be made and limitations can be imposed on the circuit board.

[0012] The limiting part one and the limiting part two are provided with inverted trapezoidal grooves on their opposite surfaces, and the limiting part one and the limiting part two are arranged in an up-down correspondence to limit the circuit board.

[0013] By adopting the above technical solution, it is convenient to limit the position of the circuit board.

[0014] The bottom of the connecting rod is fixedly connected to the second limiting part, while the connecting rod and the first limiting part are slidably connected. By adopting the above technical solution, the first limiting part can move up and down normally, thus limiting the circuit board.

[0015] The beneficial effects of the spraying device for the stepper motor driver circuit board of this utility model are:

[0016] Open the chamber door and place the stepper motor driver circuit board onto the second limiting part in the spraying chamber. Then, rotate the adjusting screw to push the lifting shaft downwards, so that the first limiting part abuts against the upper end of the stepper motor driver circuit board. Close the chamber door, and the drive motor drives the second drive wheel to rotate. In turn, the first drive wheel drives the lifting shaft to rotate synchronously. Therefore, when the first limiting part rotates, the second limiting part rotates synchronously through the rotating seat, causing the stepper motor driver circuit board to rotate. This device can quickly place stepper motor driver circuit boards of different sizes and perform automated spraying, while avoiding the paint from affecting the external processing environment during the spraying process.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Referring to Figures 1-3, a spraying device for a stepper motor driver circuit board includes a spraying chamber 1, a drive mechanism and a spraying mechanism mounted on the spraying chamber 1. The drive mechanism includes an adjusting screw 3, a lifting shaft 4, a first drive wheel 5, a motor 6, a second drive wheel 7, a first limiting part 8, a second limiting part 9, a connecting rod 10, and a rotating seat 13. The adjusting screw 3 is rotatably mounted on a bracket 2 fixed at the top of the spraying chamber 1. The lifting shaft 4 is rotatably mounted on the bottom of the adjusting screw 3 and extends downwards into the interior of the spraying chamber 1. The first drive wheel 5 is sleeved on the outer wall of the lifting shaft 4 and rotatably mounted on the spraying chamber 1. The motor 6 is mounted on the bracket 2. The second drive wheel 7 is fixedly mounted at the output end of the motor 6 and meshes with the first drive wheel 5. The first limiting part 8 is fixed to the bottom of the lifting shaft 4. The second limiting part 9 is rotatably mounted on the bottom surface inside the spraying chamber 1 via the rotating seat 13. The connecting rod 10 passes through the first limiting part 8. And the limiting part 29 at one end;

[0024] Open the door 14 and place the stepper motor driver circuit board on the limiting part 2 9 in the spraying chamber 1. Then rotate the adjusting screw 3 to push the lifting shaft 4 downward so that the limiting part 1 8 abuts against the upper end of the stepper motor driver circuit board. The stepper motor driver circuit board is limited by the limiting part 1 8 and the limiting part 2 9.

[0025] Afterwards, the compartment door 14 is closed, and the drive motor 6 drives the second drive wheel 7 to rotate. The second drive wheel 7 then controls the drive...

[0026] The first drive wheel 5 rotates, which in turn drives the lifting shaft 4 to rotate synchronously. The first limit part 8 rotates synchronously at this time. Since the first limit part 8 and the second limit part 9 are connected by the connecting rod 10, when the first limit part 8 rotates, the second limit part 9 rotates synchronously through the rotating seat 13, causing the stepper motor driver circuit board to rotate.

[0027] The spraying mechanism includes a water pipe 11 and a nozzle 12. The water pipe 11 is fixedly installed at the expansion part 101 of the spraying chamber 1. Multiple nozzles 12 are installed at equal intervals on the water pipe 11. The water pipe 11 is also connected to a connector that extends to the outside of the spraying chamber 1. When the external paint pump is started, the paint liquid is input from the connector at the outside of the spraying chamber 1 into the water pipe 11, and the stepper motor driver circuit board is sprayed through the nozzle 12.

[0028] This device can quickly place and automatically spray stepper motor driver circuit boards of different sizes, while avoiding the paint from affecting the external processing environment during the spraying process.

[0029] A groove is provided on one side of the lifting shaft 4, and the outline of the connecting hole in the middle of the drive wheel 5 is adapted to the outline of the outer wall of the lifting shaft 4; so that the lifting shaft 4 can rotate through the drive wheel 5, the motor 6 and the drive wheel 7, and ensure that the lifting shaft 4 can move up and down normally. The circuit board is limited by the limiting part 8 and the limiting part 9.

[0030] Both the first limiting part 8 and the second limiting part 9 have inverted trapezoidal grooves on their opposite surfaces, and the first limiting part 8 and the second limiting part 9 are arranged vertically to limit the circuit board; the bottom of the connecting rod 10 is fixedly connected to the second limiting part 9, and the connecting rod 10 is slidably connected to the first limiting part 8; so that the circuit board can be limited by the first limiting part 8 and the second limiting part 9, making it easy to pick up and put down, and also convenient to spray paint the circuit board.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
