Description

Technical Field

[0001] This application relates to the field of insulating film manufacturing technology for high-current aluminum alloy single-core wires, and in particular to a device and process for manufacturing insulating film for high-current aluminum alloy single-core wires. Background Technology

[0002] With the rapid development of the electric vehicle and energy storage equipment markets, the demand for high-voltage, high-current transmission is increasing. Against this backdrop, high-current aluminum alloy single-core wires are widely used in these fields due to their excellent conductivity and lightweight characteristics.

[0003] However, in order to meet the requirements of safety and reliability, these wires need to have a high-quality insulation layer. Currently, the common methods for making insulation films on the market mainly include resin spraying and dip coating, but these traditional methods often fail to achieve the ideal insulation effect when facing high-voltage environments.

[0004] Among them, the resin spraying method uses a spray gun to evenly spray liquid resin onto the aluminum wire to form a protective film. However, due to the high fluidity of liquid resin, it is prone to sagging under gravity, resulting in uneven coating thickness, which cannot meet the insulation requirements under high voltage environment. The resin immersion method involves completely immersing the aluminum wire in liquid resin and then taking it out to dry and cure. However, it also has the problem of sagging. Especially during long-term immersion, the resin may accumulate in some areas, causing local excessive thickness or thinness.

[0005] Therefore, both resin spraying and dip coating methods have problems such as uneven coating thickness and easy sagging. These problems can lead to unstable insulation film quality in practical applications, thus affecting the performance and safety of the final product. In addition, existing methods are prone to causing the insulation film to crack during subsequent processing (such as bending), which further reduces the reliability and service life of the product.

[0006] Therefore, in response to the aforementioned technical problems, a device and process for manufacturing insulating film for high-current aluminum alloy single-core wires are proposed. Summary of the Invention

[0007] To address the aforementioned issues, this application provides an equipment and process for manufacturing insulation films for high-current aluminum alloy single-core wires.

[0008] This application provides a device for manufacturing insulation film for high-current aluminum alloy single-core wires, employing the following technical solution:

[0009] An insulating film manufacturing device for high-current aluminum alloy single-core wire includes an insulating film processing table, a recovery liquid tank inside the insulating film processing table, a processing connecting block, a drying box, and a revolution motor on the top of the insulating film processing table, and a revolution collar connected to the side of the processing connecting block near the drying box via a bearing, the revolution collar being connected to the output shaft of the revolution motor via a transmission belt;

[0010] The machining connecting block and the revolution collar are connected to a rotating sleeve. A spraying assembly is fitted onto the end of the rotating sleeve near the drying chamber, and a wire pushing assembly and a rotating motor are connected to the end of the rotating sleeve away from the spraying assembly. An aluminum alloy conductive rod is inserted into the rotating sleeve. The aluminum alloy conductive rod is the raw material for manufacturing high-current aluminum alloy single-core wires. An insulating film is formed on the surface of the aluminum alloy conductive rod by uniformly spraying liquid resin onto its outer side, thus completing the production of high-current aluminum alloy single-core wires. During the production process, the aluminum alloy conductive rod is inserted into the rotating sleeve for processing, and the rotating rod rotates within the rotating sleeve driven by the rotating motor. The rotating motor drives the rotating collar and its connected rotating sleeve to complete the revolution. During the rotation, the spraying component performs the spraying work. The rotation and revolution achieve uniform spraying. During the spraying process, the pusher component pushes the aluminum alloy conductive rod to perform continuous spraying. The aluminum alloy conductive rod, which has been wrapped with insulating film, is pushed into the drying box for rapid drying to form a complete insulating film. This completes the production of the high-current aluminum alloy single-core wire. The completed high-current aluminum alloy single-core wire is collected from the drying box or enters the next production process. The liquid resin that leaks out during spraying falls into the recycling tank for subsequent centralized recycling.

[0011] Preferably, a support base is connected between the processing connecting block and the insulating film processing table, a central collar is provided at the center of the processing connecting block, and multiple sets of bearing collars are connected between the central collar and the processing connecting block, with the multiple sets of bearing collars and the central collar forming a circular array with the center as the center.

[0012] By adopting the above technical solution, the processing connecting block is used to connect the revolution collar and the rotation sleeve. The processing connecting block stands on the top of the insulating film processing table through the support base. During the revolution of the rotation sleeve, it rotates in a circular motion between the central collar and the inner side of the processing connecting block through the bearing collar.

[0013] Preferably, the rotating sleeve is inserted into the bearing ring, a liquid resin storage tank is inserted into the central ring, and multiple sets of infusion pipes are connected to the side of the liquid resin storage tank near the drying box via a bearing, with one end of the infusion pipe inserted into the spraying assembly.

[0014] By adopting the above technical solution, the liquid resin storage tank stores liquid resin for spraying, and the liquid resin in the liquid resin storage tank is transported to the spraying component for spraying through the liquid delivery pipe. The liquid resin storage tank can be replenished with liquid resin by connecting the feed pipe to the bearing on its axis according to the workload.

[0015] Preferably, a gear ring is provided on the inner side of the revolution ring, and a central gear is provided at the center of the gear ring. A transmission gear ring is provided on the outer side of the rotation sleeve, and multiple sets of transmission gear rings mesh with the central gear and the gear ring.

[0016] By adopting the above technical solution, the revolution ring, the transmission gear ring, and the central gear form a planetary gear set. During the rotation of the revolution ring, it drives the gear ring connected to it to rotate. During the rotation of the gear ring, it drives multiple sets of transmission gear rings on its inner side and the rotating sleeve connected to the transmission gear ring to perform revolution rotation. During the revolution, the rotating sleeve also performs its own rotation.

[0017] Preferably, a rotation connecting ring is provided at a position perpendicular to the rotation motor on the rotation sleeve, and the aluminum alloy conductive rod is inserted into the rotation connecting ring. The rotation connecting ring is connected to the output shaft of the rotation motor via a transmission belt.

[0018] By adopting the above technical solution, the self-rotating motor drives the self-rotating connecting ring and the aluminum alloy conductive rod connected inside it to perform individual self-rotation through the transmission belt.

[0019] Preferably, the rotating sleeve is provided with multiple sets of limiting shafts, and the limiting shafts are connected to the inner wall of the rotating sleeve through connecting shafts. The limiting shafts are provided with shaft grooves tangent to the aluminum alloy conductive rods, and the multiple sets of limiting shafts are arranged in a ring array.

[0020] By adopting the above technical solution, the aluminum alloy conductive rod inside the self-rotating sleeve is limited by the rotating shaft grooves on multiple sets of limiting rotating shafts, and can be assisted in the rotation and pushing action by multiple sets of limiting rotating shafts.

[0021] Preferably, the pusher assembly includes an electric telescopic rod and a telescopic pusher block, with one end of the electric telescopic rod connected to one side of the telescopic pusher block. The telescopic pusher block is provided with a pusher block collar, and the axis of the pusher block collar is on the same straight line as the axis of the rotating sleeve. The inner diameter of the pusher block collar is larger than the diameter of the aluminum alloy conductive rod.

[0022] By adopting the above technical solution, the pusher ring is a unidirectional diaphragm ring structure. When it moves towards the drying box, its shape does not change. Because it is in contact with one end of the aluminum alloy conductive rod, it can push the aluminum alloy conductive rod to move. When it moves away from the drying box, it will deform on the moving side, forming a hole with a larger diameter than before. Since the position of the aluminum alloy conductive rod is limited by the rotating grooves on multiple sets of limiting rotating shafts, the pusher ring will not contact the aluminum alloy conductive rod, thus not changing the position of the aluminum alloy conductive rod. The telescopic pusher is moved by the electric telescopic rod, and during the movement, the telescopic pusher drives the aluminum alloy conductive rod inside to move. The electric telescopic rod achieves the movement of the aluminum alloy conductive rod through intermittent pushing action.

[0023] On the other hand, a manufacturing process for an insulating film fabrication device for high-current aluminum alloy single-core wires includes the following steps:

[0024] Step 1: First, insert the aluminum alloy conductive rod that needs to be wrapped with insulating film into the push wire assembly, the self-rotating sleeve, the processing connecting block, and the revolution ring in sequence. The aluminum alloy conductive rod passes through the push block ring and is inserted into the self-rotating connecting ring, and then passes through multiple sets of limiting rotating shafts to reach one side of the spraying assembly.

[0025] Step 2: Then start the machine. The self-rotating motor drives the aluminum alloy conductive rod inside the self-rotating sleeve to rotate, while the orbital motor drives the orbital ring to rotate. During the rotation of the orbital ring, the self-rotating sleeve rotates around the axis of the orbital ring.

[0026] Step 3: During the rotation, the spraying component sprays and coats the aluminum alloy conductive rod. During the spraying and wrapping process, the pusher component drives the aluminum alloy conductive rod to perform intermittent pushing motions, so that the aluminum alloy conductive rod can continuously perform the insulating film wrapping action.

[0027] Step 4: The aluminum alloy conductive rod wrapped with insulating film is pushed into the drying box for rapid drying to form a complete insulating film, thus completing the production of the high-current aluminum alloy single-core wire. The completed high-current aluminum alloy single-core wire is collected from the drying box or enters the next production process.

[0028] 1. Compared with existing technologies, this high-current aluminum alloy single-core wire insulation film manufacturing equipment and process, through a complete process, makes the manufacturing process and procedures of high-current aluminum alloy single-core wire insulation film more automated, saves manpower, and improves production efficiency. A self-rotating motor drives the aluminum alloy conductive rod inside the self-rotating sleeve to rotate, while a planetary motor drives the planetary collar to rotate. During the rotation of the planetary collar, the self-rotating sleeve revolves around the axis of the planetary collar. During this rotation, a spraying component sprays and coats the aluminum alloy conductive rod with insulation film. During the spraying and wrapping process, a pushing component drives the aluminum alloy conductive rod to intermittently push, allowing the aluminum alloy conductive rod to continuously perform the insulation film wrapping action. The aluminum alloy conductive rod with the insulation film wrapped is pushed into the drying chamber for rapid drying, forming a complete insulation film, thus completing the manufacturing of the high-current aluminum alloy single-core wire.

[0029] 2. Compared with existing technologies, this high-current aluminum alloy single-core wire insulation film manufacturing equipment and its process solves the problem of easy flow of insulation films of various compositions before curing by means of rotation and revolution. This processing method can obtain uniform and complete insulation films with any required thickness by simply increasing the time, because it can rotate. This solves the problem of insulation film cracking during subsequent bending processes. The aluminum alloy conductive rod rotates in the rotating sleeve driven by the rotating motor, and the revolution motor drives the revolution collar and the rotating sleeve connected to it to complete the revolution. During the rotation, the spraying component performs the spraying work. Uniform spraying is achieved through rotation and revolution.

[0030] 3. Compared with the prior art, this high-current aluminum alloy single-core wire insulation film manufacturing equipment and process achieves continuous spraying work through intermittent pushing action. The push block collar is a unidirectional diaphragm ring structure. Its shape does not change when it moves towards the drying box. However, because it is in contact with one end of the aluminum alloy conductive rod, it can push the aluminum alloy conductive rod to move. When it moves away from the drying box, it will deform on the moving side, forming a hole with a larger diameter than before. Since the position of the aluminum alloy conductive rod is limited by the rotating shaft grooves on multiple sets of limiting rotating shafts, the push block collar will not contact the aluminum alloy conductive rod, thus not changing the position of the aluminum alloy conductive rod. The telescopic push block is moved by the electric telescopic rod, and the telescopic push block drives the aluminum alloy conductive rod inside it to move during the movement. The electric telescopic rod achieves the movement of the aluminum alloy conductive rod through intermittent pushing action. Attached Figure Description

An aluminum alloy conductive rod 7 is inserted into the rotating sleeve 4. The aluminum alloy conductive rod 7 is the raw material for making high-current aluminum alloy single-core wires. An insulating film is formed on the surface of the aluminum alloy conductive rod 7 by uniformly spraying liquid resin onto its outer side, thus completing the production of high-current aluminum alloy single-core wires. During the production process, the aluminum alloy conductive rod 7 is inserted into the rotating sleeve 4 for processing, and the aluminum alloy conductive rod 7 rotates within the rotating sleeve 4 driven by the rotating motor 43. The revolution motor 12 drives the revolution collar 3 and its connected rotating sleeve 4 to complete the revolution motion. During the rotation, the spraying component 6 performs the spraying work. The uniform spraying work is achieved through the rotation and revolution. During the spraying process, the pusher component 5 pushes the continuous spraying action. The aluminum alloy conductive rod 7, which has been wrapped with insulating film, is pushed into the drying box 8 for rapid drying to form a complete insulating film, thus completing the production of high-current aluminum alloy single-core wire. The completed high-current aluminum alloy single-core wire is collected at the drying box 8 or enters the next production process. The liquid resin that leaks out during spraying will fall into the recycling tank 11 for subsequent centralized recycling.

[0045] Reference Figure 2 and Figure 3 A support base 21 connects the processing connecting block 2 to the insulating film processing table 1. A central collar 24 is provided at the center of the processing connecting block 2, and multiple sets of bearing collars 23 are connected between the central collar 24 and the processing connecting block 2. The multiple sets of bearing collars 23 and the central collar 24 are arranged in a circular array with the central collar 24 as the center. The processing connecting block 2 is used to connect the revolution collar 3 and the rotation sleeve 4. The processing connecting block 2 stands on the top of the insulating film processing table 1 through the support base 21. During the revolution, the rotation sleeve 4 rotates in a circular motion between the central collar 24 and the inner side of the processing connecting block 2 through the bearing collar 23.

[0046] Reference Figure 3 and Figure 4The rotating sleeve 4 is inserted into the bearing collar 23, and a liquid resin storage tank 22 is inserted into the central collar 24. The side of the liquid resin storage tank 22 near the drying oven 8 is connected to multiple sets of liquid delivery pipes 221 through the bearing, and one end of the liquid delivery pipes 221 is inserted into the spraying assembly 6. The liquid resin storage tank 22 stores liquid resin for spraying, and the liquid resin in the liquid resin storage tank 22 is transported to the spraying assembly 6 through the liquid delivery pipes 221 for spraying. The liquid resin storage tank 22 can be replenished with liquid resin by connecting a feed pipe to the bearing on its axis according to the workload.

[0047] Reference Figure 5 and Figure 6 The inner side of the revolution ring 3 is provided with a gear ring 31, and a central gear 32 is provided at the center of the gear ring 31. The outer side of the rotation sleeve 4 is provided with a transmission gear ring 42, and multiple sets of transmission gear rings 42 mesh with the central gear 32 and the gear ring 31. The revolution ring 3, the transmission gear ring 42 and the central gear 32 form a planetary gear set. During the rotation of the revolution ring 3, it drives the gear ring 31 connected to it to rotate. During the rotation of the gear ring 31, it drives the multiple sets of transmission gear rings 42 on its inner side and the rotation sleeve 4 connected to the transmission gear ring 42 to perform revolution rotation. During the revolution, the rotation sleeve 4 also performs rotation.

[0048] Reference Figure 7 A rotating connecting ring 44 is provided at a position perpendicular to the rotating motor 43, and an aluminum alloy conductive rod 7 is inserted into the rotating connecting ring 44. The rotating connecting ring 44 is connected to the output shaft of the rotating motor 43 through a transmission belt. The rotating motor 43 drives the rotating connecting ring 44 and the aluminum alloy conductive rod 7 connected inside it to perform independent rotation through the transmission belt.

[0049] Reference Figure 8 The rotating sleeve 4 is provided with multiple sets of limiting shafts 41, and the limiting shafts 41 are connected to the inner wall of the rotating sleeve 4 through connecting shafts. The limiting shafts 41 are provided with shaft grooves 411 tangent to the aluminum alloy conductive rod 7, and the multiple sets of limiting shafts 41 are arranged in a ring array. The aluminum alloy conductive rod 7 inside the rotating sleeve 4 is limited by the shaft grooves 411 on the multiple sets of limiting shafts 41, and can be assisted in the rotation and pushing action by the multiple sets of limiting shafts 41.

[0050] Reference Figure 5 and Figure 9The pusher assembly 5 includes an electric telescopic rod 51 and a telescopic pusher block 52. One end of the electric telescopic rod 51 is connected to one side of the telescopic pusher block 52. A pusher block collar 521 is provided inside the telescopic pusher block 52, and the axis of the pusher block collar 521 is on the same straight line as the axis of the rotating sleeve 4. The inner diameter of the pusher block collar 521 is larger than the diameter of the aluminum alloy conductive rod 7. The pusher block collar 521 is a unidirectional diaphragm ring structure. Its shape does not change when it moves towards the drying chamber 8. However, because it is in contact with one end of the aluminum alloy conductive rod 7, it can push the aluminum alloy conductive rod 7 to move. When it moves away from the drying chamber 8, its shape changes. When the drying oven 8 moves in one direction, it deforms to the side it is moving, forming a hole with a larger diameter than before. Since the position of the aluminum alloy conductive rod 7 is limited by the rotating grooves 411 on the multiple sets of limiting rotating shafts 41, the push block collar 521 will not contact the aluminum alloy conductive rod 7, thus not changing the position of the aluminum alloy conductive rod 7. The electric telescopic rod 51 pushes the telescopic push block 52 to move, and during the movement of the telescopic push block 52, the aluminum alloy conductive rod 7 inside it moves through the telescopic push block 52. The electric telescopic rod 51 achieves the movement of the aluminum alloy conductive rod 7 through intermittent pushing action.

[0052] Step 1: First, insert the aluminum alloy conductive rod 7, which needs to be wrapped with insulating film, into the push wire assembly 5, the self-rotating sleeve 4, the processing connecting block 2, and the revolution collar 3 in sequence. The aluminum alloy conductive rod 7 passes through the push block collar 521 and is inserted into the self-rotating connecting ring 44, and reaches one side of the spraying assembly 6 through multiple sets of limiting rotating shafts 41.

[0053] Step 2: Then start the machine. The self-rotating motor 43 drives the aluminum alloy conductive rod 7 inside the self-rotating sleeve 4 to rotate. At the same time, the orbital motor 12 drives the orbital ring 3 to rotate. During the rotation of the orbital ring 3, the self-rotating sleeve 4 rotates around the axis of the orbital ring 3.

[0054] Step 3: During the rotation, the spraying component 6 sprays and coats the aluminum alloy conductive rod 7. During the spraying and wrapping process, the pusher component 5 drives the aluminum alloy conductive rod 7 to perform intermittent pushing motions, so that the aluminum alloy conductive rod 7 can continuously perform the insulating film wrapping action.

[0055] Step 4: The aluminum alloy conductive rod 7, which has been wrapped with insulating film, is pushed into the drying box 8 for rapid drying to form a complete insulating film, thus completing the production of the high-current aluminum alloy single-core wire. The completed high-current aluminum alloy single-core wire is collected from the drying box 8 or enters the next production process.
