Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, and in particular to a paint impregnation machine. Background Technology

[0002] Impregnation machines are key pieces of equipment used in equipment manufacturing for impregnation treatment, commonly used in the processing of electrical equipment such as motors and transformers. Currently, impregnation machines used for the insulation treatment of motor stator cores and windings mainly employ static impregnation, where the stator core and windings are immersed in the varnish in a fixed posture. This can easily create impregnation blind spots, especially for structures with deep grooves or tiny gaps. During static impregnation, the varnish struggles to overcome surface tension and viscosity barriers, failing to fully penetrate these structures. Furthermore, upon static removal, the varnish tends to accumulate at the bottom of the stator or the ends of the windings due to gravity, resulting in uneven varnish film thickness.

[0033] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] To overcome the problem that existing dipping machines cannot guarantee uniform dipping, a dipping machine is provided, such as... Figure 1 As shown, the impregnation machine includes an impregnation mechanism 1, a mounting frame 2, and a partition 3. The impregnation mechanism 1 is mounted on the mounting frame 2, and the partition 3 is mounted on the outside of the mounting frame 2. The partition 3 serves to insulate against heat and isolate external interference. The mounting frame 2 has an operation window 21, and a movable plate 31 is provided at the operation window. The operation window 21 is used to install or remove the motor stator core and windings, and the movable plate 31 is used to control the opening and closing of the operation window 21. For ease of description, the motor stator core and windings are now referred to as Product A.

[0035] like Figure 2 As shown, the impregnation mechanism 1 includes a plurality of rotating components 11, a plurality of clamping components 12 and a first driving component 13. One end of the first driving component 13 is mounted on the mounting frame 2, and the other end of the first driving component 13 is connected to the mounting frame 2 through the plurality of rotating components 11. A plurality of clamping components 12 are mounted on each of the rotating components 11.

[0036] The first drive assembly 13 includes a first power source 131 and a first connecting plate 132. The first connecting plate 132 is fixedly mounted on both sides of the first power source 131, and the first connecting plate 132 is fixedly connected to the mounting frame 2. The first power source 131 may be, but is not limited to, a motor. The motor shaft of the electrode passes through several of the rotating assemblies 11 and is connected to the mounting frame 2.

[0037] The rotating assembly 11 has a circular structure. Preferably, the rotating assembly 11 includes several mounting plates 111 and a frame 112. The mounting plates 111 are connected end-to-end to the frame 112 and are arranged circumferentially along the frame 112. The frame 112 is radially arranged and radiates outward from the center of the rotating assembly 11. The motor shaft of the motor is connected through the center of the frame 112 to form a force transmission path from the center to the edge. The mounting plates 111 are fan-shaped plates, and the mounting plates 111 and the frame 112 can be connected by, but is not limited to, bolts. The splicing design reduces the processing and installation difficulty of the rotating assembly 11 and facilitates local maintenance.

[0038] The clamping assembly 12 is mounted on the radial outer edge of the mounting plate 111, and the clamping assemblies 12 are disposed opposite to each other between adjacent mounting plates 111. The clamping assemblies are mounted in the mounting holes 1111 (see...). Figure 3 Within the rotating assembly 11, driven by the first driving component 13, the clamping component 12 revolves around the center of the rotating component 11. Preferably, the clamping component 12 can be mounted on both sides of the mounting plate 111 to improve the efficiency of the dipping machine. In this embodiment, the clamping components 12 arranged opposite to each other are a first clamp 121 and a second clamp 122. The first clamp 121 is fixedly connected to the first end of the product A, and the second end of the product A is rotatably connected to the second clamp 122. Relative to the mounting plate 111, the first clamp 121 will rotate axially around the center, while the second clamp 122 remains relatively stationary.

[0039] Specifically, in combination Figure 3 and Figure 4 As shown, the first clamp 121 includes a first clamp body 1211, a first mounting groove 1212, and a first sprocket 1213. The first clamp body 1211 is rotatably mounted through the mounting plate 111. The first mounting groove 1212 is formed at one end of the first clamp body 1211, and the first end of the product A is accommodated in the first mounting groove 1212. The first sprocket 1213 is also fixedly mounted on the first clamp body 1211. Preferably, the first mounting groove 1212 is snap-fitted to the product A, and the first sprocket 1213 is keyed to the first clamp body 1211. Torque transmission will occur between the first sprocket 1213, the first clamp body 1211, and the product A. In a preferred embodiment, the first mounting groove 1212 is formed at both ends of the first clamp body 1211 to optimize installation efficiency.

[0040] Combination Figure 3 and Figure 5As shown, the second clamp 122 includes a second clamp body 1221, a second mounting groove 1222, and an ejector pin 1223. The second clamp body 1221 is mounted through the mounting plate 111. The second mounting groove 1222 is formed at the end of the second clamp body 1221, and the ejector pin 1223 is disposed in the second mounting groove 1222. The second end of the product A is installed in the second mounting groove 1222, and the ejector pin 1223 abuts against the product A. Preferably, the product A and the inner wall of the second clamp body 1221 are in clearance fit. When the first clamp 121 drives the product A to rotate, relative rotation can occur between the product A and the second clamp 122, and the ejector pin 1223, together with the first clamp 121, provides axial force to the product A, ensuring the rotational stability of the product A.

[0041] Furthermore, such as Figure 2 As shown, the impregnation mechanism 1 further includes a transmission assembly 14 and a second drive assembly 15. The first clamp 121 is connected to the transmission assembly 14, and the transmission assembly 14 is connected to the second drive assembly 15. The second drive assembly 15 is mounted on the mounting frame 2. The second drive assembly 15 includes a second power source 151 and a second connecting plate 152. The second power source 151 is fixedly connected to the second connecting plate 152, and the second connecting plate 152 is fixedly connected to the mounting frame 2. The second power source 151 may be, but is not limited to, a motor. The transmission assembly 14 includes a second sprocket 141, a third sprocket 142, and a chain (not shown in the figure). The second sprocket 141 is fixedly connected to the second power source 151, and the third sprocket 142 is mounted on the mounting frame 2. Both the second sprocket 141 and the third sprocket 142 mesh with the chain. The second sprocket 141 is a drive wheel; when the second sprocket 141 rotates, the chain drives the third sprocket 142 to rotate. Meanwhile, the third sprocket 142 and the second sprocket 141 are respectively installed above and below the operation window 21, and the chain is connected to the plurality of first clamps 121 located on the rotating assembly 11 after passing through the second sprocket 141 and the third sprocket 142. The third sprocket 142 will change the connection path of the chain so that the first clamps 121 at the operation window 21 do not rotate, thereby ensuring that the product A at the operation window 21 does not rotate, so as to facilitate the installation and unloading of the product A.

[0042] In addition, combined Figure 2 and Figure 6As shown, the dipping mechanism 1 further includes a paint tank assembly 16, which is mounted below the rotating assembly 11. The paint tank assembly 16 includes a paint tank 161 and a driving component 162. The driving component 162 is connected to the paint tank 161 and is mounted on the mounting bracket 2. The paint tank 161 contains liquid paint, and the driving component 162 can raise and lower the paint tank 161 to improve process adaptability and accommodate products A of different sizes. Preferably, the paint tank 161 is a U-shaped paint tank. During the dipping process, after the paint tank 161 is adjusted to a suitable position by the drive component 162, the first clamp 121 located on the lower side of the rotating component 11 drives the product A to rotate, so that every contact surface of the product A can be fully dipped in paint during the dipping process, effectively avoiding blind spots in the dipping process; the first clamp 121, which leaves the paint liquid and has not reached the operation window 21, will continue to drive the product A to rotate, so that the product A will shake off excess paint liquid under the combined action of centrifugal force and gravity, ensuring the paint film thickness on the surface of the product A.

[0043] The dipping machine also includes a drying mechanism 4, which comprises a heating element 41 and a fan 42. The heating element 41 is installed inside the mounting frame 2, and the fan 42 is mounted on the mounting frame 2. The heating element 41 can be, but is not limited to, a heating lamp. The heating lamp, in conjunction with the heat insulation plate, provides a temperature basis for the drying and curing of the paint on product A, while also improving operational visibility. With the further assistance of the fan 42, convection drying efficiency is enhanced, waste gas is effectively eliminated, and process stability and environmental safety are ensured.

[0044] In addition, the bottom of the mounting bracket 2 is provided with rollers 22, which facilitates the handling of the dipping machine.

[0045] During operation, the operator engages the first end of product A with the first clamp 121 through the operation window 21, and the second end of product A with the second clamp 122. Upon activation of the first drive assembly 13 and the second drive assembly 15, the first drive assembly 13 drives the rotating assembly 11 to rotate, thereby causing the first clamp 121 and the second clamp 122 to revolve synchronously. Product A, installed between the first clamp 121 and the second clamp 122, also revolves synchronously. The second drive assembly 15 drives the second sprocket 141 to rotate. Under the coordinated action of the chain, the third sprocket 142, and the first sprocket 1213, the first clamp 121, which has not passed through the operation window 21, will rotate synchronously, thereby causing product A to rotate. When product A is immersed in paint during its revolution, the first clamp 121 and product A are in a rotating state. The dynamic flow effect generated by this rotation optimizes the paint coverage. After the coating is completed, product A continues its revolution and leaves the paint liquid. The first clamp 121 and product A continue to rotate, and the rotation generates centrifugal force and gravity to remove excess paint and optimize uniformity. Simultaneously, the drying mechanism 4 accelerates the drying and curing of the paint film on the surface of product A. When product A reaches the operating window 21, guided by the second sprocket 141 and the third sprocket 142, both the first clamp 121 and product A stop rotating, maintaining only their revolution, so that the coated product A can be removed and the product A requiring further coating can be installed.

[0046] In summary, this utility model provides a paint dipping machine. By installing the first clamp 121 and the second clamp 122 on the rotating assembly 11 and driving the rotating assembly 11 with the first drive assembly 13, the first clamp 121 and the second clamp 122 can revolve around each other. At the same time, the first clamp 121 rotates under the transmission of the transmission assembly 14 and the second drive assembly 15, which effectively realizes dynamic contact between the product and the paint liquid, reduces the paint dipping blind zone, and improves the paint dipping uniformity and coverage.
