Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically to a varnishing apparatus for producing motors. Background Technology

[0002] Motor impregnation is a key process in motor manufacturing and maintenance. Its core purpose is to improve the insulation performance, mechanical strength and environmental adaptability of the motor through the penetration, filling and curing of insulating varnish, thereby extending its service life and ensuring safe operation.

[0003] In existing technologies, lifting equipment is generally used to immerse motor components, such as stators or rotors, that require paint impregnation into an insulating paint bath, and then lift them out. However, after the components are lifted out, they are left to stand for paint drying, which allows excess paint to flow back into the paint bath to prevent waste. But this has a problem: the entire equipment stops while waiting for the paint to flow back, and the drying stage requires about 5 minutes of standing time, which can easily affect the overall production efficiency. Therefore, an improved paint impregnation device for motor production is needed to address this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for impregnating motors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coating impregnation device for producing motors, comprising a storage tank, receiving plates fixedly disposed on both sides of the surface of the storage tank, and a lifting mechanism for lifting motors for coating impregnation disposed at the upper end of the storage tank, the lifting mechanism comprising a column, a slide rail, a slider, an electric hoist, a lifting rope, a basket, and an electric push rod, a column fixedly disposed at each of the four corners of the outer side of the storage tank, a slide rail fixedly disposed on the column, a slider movably engaged on the outer surface of the slide rail, so that the slider can move left and right along the upper end of the slide rail, an electric hoist fixedly disposed at the lower end of the slider, two electric hoists being disposed evenly spaced on both sides of the lower end of the slider, a lifting rope wound around the outer surface of the electric hoist, a basket fixedly disposed at the lower end of the lifting rope, and an electric push rod fixedly disposed on one side of the upper end of the column, the movable end of the electric push rod being fixedly connected to the slider, so that when the electric push rod retracts, it can drive the slider to move along the slide rail.

[0006] Preferably, the lower end of the electric hoist is provided with a fixed frame, and the hoisting rope is disposed inside the fixed frame. The range of swing of the hoisting rope can be set by the fixed frame.

[0007] Preferably, the lower end of the receiving tray is fixedly provided with a support leg, which can ensure the stability of the receiving tray. The receiving tray can be used to receive the insulating varnish left when the basket is stationary. Then, the varnish can automatically slide down the receiving tray and flow back into the storage tank, so as not to waste it.

[0008] Preferably, the lower outer surface and side of the basket are evenly provided with several through grooves, which can facilitate the discharge of varnish and improve the discharge efficiency.

[0009] Preferably, a remote control is fixedly installed on the surface of the column. The remote control is electrically connected to the electric hoist and the electric push rod respectively. The remote control can be used to conveniently control the electric hoist to perform winding work and to conveniently control the electric push rod to extend or shorten.

[0010] Preferably, a sealing cover is movably provided on one side of the upper end of the storage tank via a rotating shaft. When workers leave work, the storage tank can be sealed with the sealing cover to prevent unnecessary evaporation and to prevent the insulating varnish from deteriorating.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This invention is equipped with multiple processing and dipping stations. While one station is performing the paint dipping operation, another station can simultaneously perform the static loading and unloading operation, thus making full use of the time. The specific operation is as follows.

[0013] 2. The present invention is simple to operate. By extending and retracting the electric push rod, when one station is aligned with the storage tank, the other station is aligned with the receiving plate. The operation is not complicated, so it can be easily promoted and used. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 This invention provides a technical solution: a varnish impregnation device for producing motors, comprising a storage tank 11, which serves as a storage container for insulating varnish, with receiving trays 2 fixedly installed on both sides of its surface. The main function of the receiving trays 2 is to receive the insulating varnish dripping from the suspended basket 8 when it is stationary, preventing varnish waste and environmental pollution. Support legs 11 are fixedly installed at the lower end of the receiving trays 2, providing stable support and ensuring that the receiving trays 2 remain stable during operation, allowing the dripping insulating varnish to smoothly slide down the receiving trays 2 and flow back into the storage tank 1, thus realizing the recycling of the insulating varnish.

[0020] A lifting mechanism is installed at the top of the storage tank 1. The lifting mechanism is the core part of this device and is used to lift the motor for the paint dipping operation. The lifting mechanism includes a column 3, a slide rail 4, a slider 5, an electric hoist 6, a lifting rope 7, a basket 8, and an electric push rod 9.

[0021] Each of the four corners of the storage tank 1 is fixedly equipped with a column 3, which provides a stable support frame for the entire lifting mechanism. A slide rail 4 is fixedly mounted on the column 3, and a slider 5 is movably engaged on the outer surface of the slide rail 4, allowing the slider 5 to move smoothly left and right along the upper end of the slide rail 4. Two electric hoists 6 are fixedly mounted at the lower end of the slider 5, and the two electric hoists 6 are evenly spaced on both sides of the lower end of the slider 5. A lifting rope 7 is wound around the outer surface of each electric hoist 6, and a basket 8 is fixedly mounted at the lower end of the lifting rope 7 for placing the motor to be dipped in paint.

[0022] An electric push rod 9 is fixedly installed on one side of the upper end of the column 3, and the movable end of the electric push rod 9 is fixedly connected to the slider 5. When the electric push rod 9 retracts or extends, it can drive the slider 5 to move along the slide rail 4, thereby realizing the horizontal position adjustment of the basket 8, which facilitates the accurate lifting of the motor into or out of the storage tank 1.

[0023] The electric hoist 6 has a fixed frame 10 at its lower end, and the lifting rope 7 is installed inside the fixed frame 10. The function of the fixed frame 10 is to limit the sway range of the lifting rope 7, so as to prevent the lifting rope 7 from swaying too much during the lifting process, which would cause the motor to shake, affecting the coating effect and operational safety.

[0024] The lower outer surface and sides of the suspended basket 8 are evenly provided with several through slots. The design of these through slots allows the insulating varnish to be quickly discharged through the through slots when the suspended basket 8 is lifted from the storage tank 1, which improves the varnish control efficiency, reduces the amount of insulating varnish remaining on the motor surface, and is beneficial for subsequent drying and processing.

[0025] A remote control 12 is fixedly installed on the surface of the column 3. The remote control 12 is electrically connected to the electric hoist 6 and the electric push rod 9. Through the remote control 12, the operator can conveniently remotely control the electric hoist 6 to perform winding or unwinding operations and adjust the lifting height of the suspended platform 8. At the same time, the operator can also conveniently remotely control the electric push rod 9 to extend or retract, realizing the horizontal movement of the suspended platform 8, making the operation more convenient and flexible.

[0026] A sealing cover 13 is movably mounted on one side of the upper end of the storage tank 1 via a pivot. When workers leave work or the device is not used for a long time, the storage tank 1 can be sealed with the sealing cover 13 to effectively prevent the insulating varnish from excessively contacting the air and causing unnecessary evaporation, while also preventing the insulating varnish from deteriorating due to contact with external impurities, thus ensuring the quality and performance of the insulating varnish.

[0027] Working principle: When using this device, the storage tank 1 is partially buried below the ground. This device has multiple processing and impregnation stations; taking two stations as an example (this can be expanded according to actual needs), while one station is performing the paint impregnation operation, the other station can simultaneously perform static loading and unloading operations, maximizing time utilization. Specific operation is as follows:

[0028] Workers control the extension or retraction of the electric push rod 9 via remote control 12. Since the movable end of the electric push rod 9 is fixedly connected to the slider 5, and the slider 5 is movably engaged with the outer surface of the slide rail 4 on the column 3, the extension and retraction of the electric push rod 9 can drive the slider 5 to move left and right along the slide rail 4. Ultimately, one basket 8 is positioned above the storage tank 1, and the other basket 8 is positioned above the receiving plate 2. The basket 8 on the storage tank 1 can then be lowered by the electric hoist 6 into the storage tank 1 for varnish impregnation. The other basket 8 remains stationary to facilitate the removal of excess insulating varnish from the motor assembly. The removed varnish drips onto the receiving plate 2, and then automatically slides down the receiving plate 2 back into the storage tank 1, preventing varnish waste. After the varnish has dried, workers can remove the varnished motor stator or rotor from the basket 8 and insert a new motor stator or rotor that needs processing. In this way, the device can fully utilize the varnish impregnation time, with the two processing stations alternating continuously, avoiding equipment downtime due to waiting for varnish return and significantly improving the processing efficiency of the device.
