Description

Technical Field

[0001] This invention relates to the field of automotive motor manufacturing technology, and more specifically to a rapid-drying dip-coating apparatus for automotive motor manufacturing. Background Technology

[0002] The automotive starter motor, also known as a motor, converts electrical energy from the battery into mechanical energy to drive the engine flywheel and start the engine. Dip coating is a common motor protection technology widely used in the manufacturing process of electric motors and transmission systems in the automotive industry. Its main purpose is to improve the durability and performance of the motor in various working environments by applying a protective coating to the surface of motor components. With the acceleration of automotive electrification, the protection requirements for electric vehicle motors are becoming increasingly stringent, especially in terms of waterproofing, dustproofing, and corrosion resistance. Dip coating technology can effectively solve these problems. This process typically uses materials such as polyurethane, epoxy resin, or acrylic resin. These coatings have good electrical insulation, high temperature resistance, and chemical corrosion resistance, providing the necessary protective layer during motor operation. In addition, the dip coating process can reduce friction between internal motor components, improve mechanical efficiency, and extend the motor's service life. Dip coating not only improves the overall performance of the motor but also enhances its reliability in harsh environments, ensuring its long-term stable operation. With technological advancements, the dip coating process is gradually moving towards automation and precision, further improving coating consistency and quality control.

[0003] A Chinese patent (publication number: CN209772607U) discloses a rapid-drying dip-coating device for automotive motor production. This device eliminates the need to remove the automotive motor from other equipment during the entire process from preheating to drying, saving significant time and steps. The paint control process can be completed without additional specialized equipment, and the wiping process is omitted, replaced by a faster procedure. The automotive motor is placed in a basket under a trolley device, rapidly preheated by a hot air blower, and then immersed in a paint dip tank. The basket is then lifted to allow the paint to be controlled; excess paint drips back into the dip tank for reuse, saving resources and protecting the environment. The motor is then sent into a drying chamber where temperature-controlled heating elements meet the requirements of drying the automotive motor from a low temperature to a high temperature. There are air vents at the back of the heating tubes, and the generated heat is quickly blown onto the car motor. At the same time, this airflow can also accelerate evaporation, making the drying process faster. There is a paint drip tray at the bottom of the drying chamber. If there is excess paint on the car motor that has not been cleaned, it will drip into the tray. Since the heating tubes are parallel to the basket, the paint will not drip onto the heating tubes, which enhances safety. In the actual process of dipping the motor, the paint comes into contact with air during dipping, which will cause air bubbles to form, resulting in uneven coating and poor adhesion. At the same time, the paint is difficult to penetrate into the gaps of complex parts such as motor windings and coils, thereby reducing the motor's insulation and corrosion resistance.

[0007] The inside of the directional roller is fitted with a base plate.

An insert rod is fixedly connected to the inner side of the locking block. The insert rod is slidably inserted into the fixing block. The lower end of the insert rod is rotatably connected to a second receiving block. A second servo motor is fixedly installed on the lower surface of the second receiving block. The output shaft of the second servo motor is fixedly connected to the insert rod.

[0008] Furthermore, multiple sets of connecting rods are fixedly connected to the lower surface of the second receiving block, and the lower ends of the multiple sets of connecting rods are all fixedly connected to the first receiving block. An electric telescopic rod is fixedly installed inside the dipping tank, and the output end of the electric telescopic rod is fixedly connected to the first receiving block.

[0009] Furthermore, two sets of sliding rods are fixedly connected inside the frame, and two sliders are slidably inserted into the surface of each set of sliding rods. The sliders are fixedly connected to the receiving plate and fit against the inner wall of the frame.

[0010] Furthermore, a sealing plate is attached to the surface of the directional roller, the sealing plate is fixedly connected to the dip coating tank, a partition is attached to the surface of the directional roller, the partition is fixedly connected to the dip coating tank, and the sealing plate is fixedly connected to the partition.

[0011] Furthermore, a scraper is attached to the surface of the directional roller, and a drainage groove is provided inside the scraper. A connecting plate is fixedly connected to one side of the scraper. The connecting plate is attached to the sealing plate, and two sets of bolts are inserted inside the connecting plate. Both sets of bolts are threadedly connected to the sealing plate.

[0012] Furthermore, an air outlet is fixedly installed inside the dip coating chamber, and a heating tube is fixedly installed inside the dip coating chamber.

[0013] Furthermore, a door is fixedly installed on the surface of the dipping tank, an observation window is fixedly installed inside the door, and a handle is fixedly installed on the surface of the door.

[0014] Furthermore, a controller is fixedly mounted on the surface of the dip coating tank, a display screen is fixedly mounted on the surface of the controller, and buttons are fixedly mounted on the surface of the controller.

[0015] Furthermore, four sets of bases are fixedly installed on the lower surface of the dip coating tank, and all four sets of bases are located on the same horizontal plane.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. In this invention, when dipping an automotive motor, a base plate and its internally fixed motor are installed into the interior of a directional roller using insert rods and locking blocks. A servo motor is then activated, driving a rotating rod and the directional roller to rotate, causing the motor inside the directional roller to rotate to the fixed plate. Air is evacuated from the base plate through an air intake, vacuum pump, and exhaust pipe, creating a vacuum state. The servo motor then rotates the base plate to the bottom, making it face downwards. An electric telescopic rod then moves the base plate and motor vertically downwards, causing the motor to... The paint comes into contact with the motor, thus immersing it in the coating. After immersion, the base plate is rotated back to its original position, and the motor is dried through the air outlet and heating element. This process is repeated after drying to ensure a more thorough immersion coating. This component effectively avoids the problem of air bubbles being generated when the paint mixes with air during motor immersion, achieving a vacuum immersion coating effect. At the same time, it makes the paint surface more uniform, improves the adhesion of the paint, and facilitates the penetration of the paint into the gaps of complex parts such as motor windings and coils. It also improves the insulation and corrosion resistance of the automotive motor.

[0018] 2. When fixing the motor, multiple sets of motors are placed on the upper surface of the base plate. Turning the knob rotates the bidirectional threaded rod, causing the two sets of sliders threaded to the surface of the bidirectional threaded rod to move the receiving plate and grippers horizontally in opposite directions. This allows the opposing grippers to gradually fit against the surface of the motor, thus fixing the motor to be coated. After the motor is fixed, the base plate is placed inside the directional roller, so that the frame fits against the inner wall of the directional roller. The electric telescopic rod is activated, which drives the receiving block, connecting rod, and bearing... Block 2, the insert rod, and the locking block move vertically upwards, thereby inserting the locking block and the insert rod into the interior of the fixed block. The servo motor 2 drives the insert rod and the locking block to rotate, causing the locking block to engage with the inner wall of the fixed block, thus fixing the base plate to the output end of the electric telescopic rod. The design of this component effectively avoids the problem of the motor tipping over when dipping the car motor, achieving the effect of limiting the motor. At the same time, it improves the stability of the device during dipping and facilitates the collection of the motor after dipping, improving the convenience of the device in use.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1, as Figures 1-8 As shown, a rapid-drying dip coating device for automobile motor production includes a dip coating tank 1. The dip coating tank 1 has a dip coating mechanism 2 inside. The dip coating mechanism 2 includes a directional roller 25, a servo motor 26, a rotating rod 27, an air intake 28, a fixed plate 29, a vacuum pump 210, and an exhaust pipe 211. The servo motor 26 is fixedly connected to the dip coating tank 1. The output shaft of the servo motor 26 is fixedly connected to the rotating rod 27. The rotating rod 27 is rotatably connected to the dip coating tank 1. The rotating rod 27 is fixedly connected to the directional roller 25, which is in contact with the inner wall of the dip coating tank 1. The fixed plate 29 is fixedly connected to the dip coating tank 1 and the air intake 28. The vacuum pump 210 is fixedly connected to the fixed plate 29, and the exhaust pipe 211 is fixedly connected to the vacuum pump 210.

[0030] The inside of the adjusting roller 25 is fitted with a base plate 41. A fixing mechanism 4 is provided on the upper surface of the base plate 41. The fixing mechanism 4 includes a receiving plate 42, a frame 43, a knob 45, a gripper 46, a slider 47, and a bidirectional threaded rod 48. The frame 43 is fixedly connected to the base plate 41, the bidirectional threaded rod 48 is rotatably connected to the frame 43, the bidirectional threaded rod 48 is threadedly connected to the slider 47, the knob 45 is fixedly connected to the bidirectional threaded rod 48, and the receiving plate 42 is fixedly connected to the slider 47. 2. It fits against the inner wall of the frame 43. The gripper 46 is fixedly connected to the receiving plate 42. Two sets of fixing blocks 44 are fixedly connected to the lower surface of the base plate 41. Each of the two sets of fixing blocks 44 has a locking block 54 inside. The inner side of the locking block 54 is fixedly connected to the insertion rod 53. The insertion rod 53 is slidably inserted into the fixing block 44. The lower end of the insertion rod 53 is rotatably connected to the second receiving block 56. The lower surface of the second receiving block 56 is fixedly installed with the second servo motor 55. The output shaft of the second servo motor 55 is fixedly connected to the insertion rod 53.

[0031] The main purpose of dip coating for automotive motors is to improve the durability and performance of the motor in various working environments by applying a protective coating to the surface of the motor components. Polyurethane, epoxy resin, or acrylic resin are typically used as the protective layer during dip coating. When dip coating an automotive motor, firstly, multiple motors are placed on the upper surface of the base plate 41. Turning the knob 45 rotates the bidirectional threaded rod 48, causing the two sets of sliders 47 threaded to the surface of the bidirectional threaded rod 48 to move the bearing... The receiving plate 42 and the gripper 46 move horizontally in opposite directions, causing the opposing gripper 46 to gradually adhere to the surface of the motor, thereby fixing the motor to be coated. Then, the base plate 41 is placed inside the directional roller 25, so that the frame 43 adheres to the inner wall of the directional roller 25. The electric telescopic rod 5 is activated, which drives the receiving block 1 51, connecting rod 52, receiving block 2 56, insert rod 53, and locking block 54 to move vertically upward, thereby inserting the locking block 54 and insert rod 53 into the interior of the fixing block 44. Servo motor 255 drives the insertion rod 53 and the locking block 54 to rotate, causing the locking block 54 to engage with the inner wall of the fixing block 44, thereby fixing the base plate 41 to the output end of the electric telescopic rod 5. Then, the insertion rod 53 and the locking block 54 are used to install the base plate 41 and the motor fixed inside it into the interior of the directional roller 25. Servo motor 26 is started, which drives the rotating rod 27 and the directional roller 25 to rotate, causing the motor inside the directional roller 25 to rotate to the fixing plate 29, and through the air intake 28, the vacuum... The air pump 210 and the exhaust pipe 211 evacuate the air inside the base plate 41, making the base plate 41 a vacuum state. The servo motor 26 rotates the base plate 41 to the bottom, so that the base plate 41 faces downward. The electric telescopic rod 5 drives the base plate 41 and the motor to move vertically downward, so that the motor comes into contact with the paint and is dipped in the paint. After dipping, the base plate 41 is rotated back to its original position, and the motor is dried through the air outlet 21 and the heating pipe 22. After drying, this operation is repeated to make the motor dipped more thoroughly.

[0032] Example 2, as Figure 8 As shown, based on the above embodiment, it also includes multiple sets of connecting rods 52 fixedly connected to the lower surface of the receiving block 2 56, and receiving block 1 51 fixedly connected to the lower end of each set of connecting rods 52. An electric telescopic rod 5 is fixedly installed inside the dipping tank 1. The output end of the electric telescopic rod 5 is fixedly connected to the receiving block 1 51. The electric telescopic rod 5 drives the base plate 41 and the motor to move vertically downward, so that the motor comes into contact with the paint liquid, thereby dipping the motor.

[0033] Example 3, as Figure 7 , Figure 8As shown, based on the above embodiment, it also includes two sets of sliding rods 49 fixedly connected inside the frame 43. Sliding sliders 410 are slidably inserted into the surface of both sets of sliding rods 49. Sliding sliders 410 are fixedly connected to the receiving plate 42 and fit against the inner wall of the frame 43. The sliding rods 49 limit the sliding sliders 410, making the receiving plate 42 more stable when moving horizontally.

[0034] Example 4, as Figure 5 , Figure 6 As shown, based on the above embodiment, it also includes a sealing plate 24 attached to the surface of the directional roller 25, the sealing plate 24 being fixedly connected to the dip coating tank 1, a partition plate 23 attached to the surface of the directional roller 25, the partition plate 23 being fixedly connected to the dip coating tank 1, and the sealing plate 24 being fixedly connected to the partition plate 23. The dip coating chamber inside the dip coating tank 1 is sealed by the partition plate 23 and the sealing plate 24 to prevent external air from entering the dip coating chamber, thereby avoiding the problem of needing to extract air before each dip coating of the motor, reducing the cumbersomeness of use and reducing energy consumption.

[0035] Example 5, as Figure 5 , Figure 6 As shown, based on the above embodiment, it also includes a scraper 3 attached to the surface of the directional roller 25, a drain groove 31 opened inside the scraper 3, a connecting plate 32 fixedly connected to one side of the scraper 3, the connecting plate 32 being attached to the sealing plate 24, and two sets of bolts 33 inserted inside the connecting plate 32, both sets of bolts 33 being threadedly connected to the sealing plate 24. When the motor finishes dipping and returns to its original position, the rotation of the directional roller 25 causes the scraper 3 to scrape off the paint adhering to its surface, preventing paint residue from remaining on the surface of the directional roller 25 and causing changes in the size of the directional roller 25.

[0036] Example 6, as Figure 1 , Figure 2 As shown, based on the above embodiment, it also includes an air outlet 21 fixedly installed inside the dip coating tank 1, a heating tube 22 fixedly installed inside the dip coating tank 1, a door 14 fixedly installed on the surface of the dip coating tank 1, an observation window 15 fixedly installed inside the door 14, a handle 16 fixedly installed on the surface of the door 14, a controller 11 fixedly installed on the surface of the dip coating tank 1, a display screen 12 fixedly installed on the surface of the controller 11, and buttons 13 fixedly installed on the surface of the controller 11. Four sets of bases 17 are fixedly installed on the lower surface of the dip coating tank 1, and the four sets of bases 17 are all located on the same horizontal plane. The motor after dip coating can be dried through the air outlet 21 and the heating tube 22. The observation window 15 allows the staff to easily observe the motor during drying. At the same time, the controller 11 allows the speed, drying temperature, etc. of the device to be easily adjusted.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
