Description

Technical Field

[0001] This invention relates to the technical field of copper and aluminum busbar processing equipment, specifically to a method and equipment for uniformly coating the insulating layer of copper and aluminum busbars. Background Technology

[0002] The insulation layer of copper-aluminum busbars is an insulating material layer wrapped around the surface of the copper-aluminum busbars that can block the conduction of current. Its purpose is mainly to prevent the copper-aluminum busbars from accidentally coming into contact with other conductors or grounding components, which could cause leakage, short circuits, and other problems. This ensures the safe operation of the electrical system and avoids equipment failures or safety accidents caused by current leakage. The methods of setting the insulation layer usually include brushing insulating varnish, dip coating, and sleeve. Dip coating refers to completely immersing the copper-aluminum busbars in liquid insulating varnish or rubber dust, allowing the insulating material to penetrate into the surface and gaps. After removal, it is cured to form a gapless insulation layer.

[0003] When applying copper and aluminum immersion powder, adjustable clamping arms or fixtures adapted to different workpiece shapes are often used. During the immersion process, the material needs to flow, adhere, or melt to cover the workpiece surface. However, the contact pressure of the clamping part makes the gap between the workpiece and the clamping part extremely small. During use, the clamping part directly contacts and blocks the clamping point area, making it impossible for the immersion material to fully cover or adhere to the contact position. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a uniform coating device for copper-aluminum busbar insulation, including a fixed frame, a fluidized bed fixedly connected to the outer wall of the fixed frame, a fixed platform fixedly connected to the top of the fixed frame, two sprockets rotatably connected to the top of the fixed platform, a chain provided on the top of the fixed platform, both sprockets meshing with the chain, an annular slide rail fixedly connected to the top of the fixed frame, and a motor fixedly connected to the outer wall of the fixed platform, and further including: The clamping mechanism consists of several clamping mechanisms, all of which are slidably connected to the outer wall of the annular slide rail. They are used to clamp and fix the copper and aluminum busbars, ensuring that they remain stable during movement and preventing them from shifting. The top block mechanism consists of several top block mechanisms, all of which are slidably connected to the outer wall of the clamping mechanism to adjust the clamping position of the clamping mechanism. The limiting mechanism is located on the outer wall of the clamping mechanism to limit the running trajectory of the clamping mechanism and reduce the difficulty of loading and unloading. The sprocket on the left side, driven by a motor, moves the chain and clamps the copper and aluminum bars through a clamping mechanism, allowing the copper and aluminum bars to enter the fluidized bed in sequence to complete the production.

[0005] Preferably, the clamping mechanism includes: The telescopic component is slidably connected to the outer wall of the annular slide rail via a telescopic element. The telescopic component includes a support plate fixedly connected to the outer wall of the chain, and a telescopic rod is fixedly connected to the outer wall of the support plate; The clamping assembly is fixedly connected to the outer wall of the telescopic rod via a protective component; The protective component includes a protective shell that is fixedly connected to the end of the telescopic rod away from the support plate; The telescopic component drives the clamping component to move, allowing the clamped copper and aluminum busbars to be fully immersed in the fluidized bed.

[0006] Preferably, the top block mechanism includes: The switching component is slidably connected to the inner wall of the protective shell; A reset component is fixedly connected to the outer wall of the switching component. The reset component, after moving to the side closest to the motor, pushes the switching component to change its state, thereby altering the clamping position of the clamping mechanism on the copper-aluminum busbar.

[0007] Preferably, the limiting mechanism includes: Limiting components are provided on the outer wall of the fixed platform; The power assist components are provided in several parts, and all of them are slidably connected to the top of the protective shell via a pressing component; The pressing component includes a sliding column that is slidably connected to the inner wall of the protective housing; The limiting component is used to restrict the position of the clamping component, and the assist component is used to adjust the position of some parts of the clamping component.

[0008] Preferably, the telescopic component includes a slider fixedly connected to the outer wall of the support plate, and the outer wall of the slider is slidably connected to the annular slide rail; The chain drives the slider to slide on the outer wall of the annular slide rail, which in turn drives the clamping assembly to move along the annular slide rail.

[0009] Preferably, the clamping assembly includes several fixing rods fixedly connected to the inner wall of the protective shell, two springs are sleeved on the outer wall of each fixing rod, several clamping plates are slidably connected to the outer wall of the fixing rods, and several contact pins are fixedly connected to the outer wall of each clamping plate; the clamping plates are fixedly connected to the springs. Among them, several springs are located between the clamping plate and the protective shell. The springs on the side away from the annular slide rail are initially in a free state, while the springs on the side closer to the annular slide rail are initially in a compressed state under the pressure of the switching component.

[0010] Preferably, the switching component includes a support shaft slidably connected to the inner wall of the protective shell, and a top block is fixedly connected to the side of the support shaft away from the annular slide rail; The top block is elliptical and is used to adjust the distance between the two clamping plates on the side that they are close to each other. The reset assembly includes a limiting plate 1 fixedly connected to the outer wall of the support shaft, and a spring 2 sleeved on the outer wall of the support shaft, with the outer wall of the spring 2 fixedly connected to the outer wall of the limiting plate 1. Among them, spring two is located between limiting plate one and protective shell, and spring two is initially in a free state.

[0011] Preferably, the limiting component includes a limiting groove formed on the outer wall of the fixed platform, a sliding groove formed on the outer wall of the fixed platform, a limiting rod fixedly connected to the outer wall of the protective shell, the limiting rod being adapted to the limiting groove, and the end of the support shaft away from the top block contacting the inner wall of the sliding groove. The chute is disconnected on the side closest to the fluidized bed, and a buffer slope is provided at the disconnection point. The support shaft moves along the chute, and during use, the limiting rod will slide along the inner wall of the limiting groove.

[0012] Preferably, the assist component includes a limiting plate two fixedly connected to the outer wall of the slide column, and two top plates rotatably connected to the bottom of the slide column; The two top plates are at an angle to each other, and the ends of the two top plates away from the sliding column are rotatably connected to the inner walls of the two clamping plates respectively.

[0013] The method for using the equipment for uniformly coating copper-aluminum busbar insulation includes the following steps: S1: Equipment installation: Before use, ensure that the fluidized bed is working properly and that it is filled with rubber powder. Then, when using it, connect the power supply to the motor. S2: Manual feeding: The staff takes out the heated copper and aluminum busbars, presses the sliding column, and puts the copper and aluminum busbars into the clamping assembly to ensure that the copper and aluminum busbars are horizontal and the copper and aluminum busbars are clamped securely. S3: Start-up equipment: The sprocket on the left side, driven by the motor, moves the chain, causing the copper and aluminum bars to enter the fluidized bed in sequence, thus completing the production.

[0014] The present invention has the following beneficial effects: (1) After the material is loaded, during the movement process, the support shaft contacts the chute. When the support shaft moves to the buffer slope on the chute, the support shaft moves, driving the top block on the support shaft to move. At this time, the widest point of the top block is transferred from the existing two clamping plates to the other two clamping plates. Figure 6 As shown, the two clamping plates on the right side clamp the copper and aluminum plates, while the two clamping plates on the left side are affected by the top block and do not clamp the copper and aluminum plates. When the copper and aluminum plates are completely immersed in the fluidized bed, the clamping points are switched. The clamping point area changes during the powder dipping process, so that the dip coating material fully covers or adheres to the clamping point area.

[0015] (2) This invention utilizes the characteristics of the top block's movement, such as Figure 7When the support shaft moves in contact with the buffer slope, the highest point of the top block leaves the two clamping plates on the left. At this time, the two clamping plates on the left hold the raw material. As the support shaft continues to move, the highest point of the top block enters the gap between several clamping plates. At this time, the two clamping plates on the left and the two clamping plates on the right simultaneously hold the copper-aluminum plate. As the support shaft continues to move, the widest point of the top block contacts the two clamping plates on the right, increasing the gap and preventing the two clamping plates on the right from holding the copper-aluminum plate, thus achieving the desired effect. Figure Nine Similarly, when the support shaft moves to another buffer slope, the clamping position is changed, eliminating the problem of raw materials falling or tilting due to the non-clamping state during the exchange process.

[0016] (3) The present invention utilizes the characteristics of the limiting rod and the limiting groove. The copper and aluminum busbars are clamped and move along the slide groove. At the corner of the slide groove, the height of the copper and aluminum busbars decreases and enters the fluidized bed. During the immersion process, due to the continuous movement of the chain, the clamping device moves at a constant speed, so that the copper and aluminum busbars move at a constant speed in the fluidized bed. In addition, since the movement trajectory of the copper and aluminum busbars is semi-circular during the immersion process, the area swept by the copper and aluminum busbars in the fluidized bed is fan-shaped, which reduces the void phenomenon generated during the immersion process and improves the uniformity of immersion.

[0017] (4) This invention utilizes the characteristic of the spring pushing the clamping plate to set up a clamping assembly. During the clamping process, when the spring is in a free state, the distance between the two clamping plates is less than the thickness of the copper-aluminum plate, such as... Figure 6 After clamping the copper-aluminum busbar, the four springs on the left side change from a free state to a compressed state. At this time, the two clamping plates exert opposing pressure on the copper-aluminum busbar, causing several contact pins fixed on the clamping plates to abut against the copper-aluminum busbar. In addition, several contact pins on the two clamping plates are misaligned and rotated, causing the copper-aluminum busbar to tilt slightly during the clamping process, which improves the stability of the copper-aluminum busbar during the clamping process and reduces the probability of the copper-aluminum busbar shaking and falling off during movement.

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.

The device also includes: Clamping mechanism 1, several clamping mechanisms 1 are provided, and several clamping mechanisms 1 are slidably connected to the outer wall of the annular slide rail 18 for clamping and fixing the copper and aluminum busbars to ensure that they are in a stable state during movement and do not shift. A top block mechanism 2 is provided, and several top block mechanisms 2 are slidably connected to the outer wall of the clamping mechanism 1 to adjust the clamping position of the clamping mechanism 1. Limiting mechanism 3 is installed on the outer wall of clamping mechanism 1 to limit the running trajectory of clamping mechanism 1 and reduce the difficulty of loading and unloading. In this process, the sprocket 16 on the left side, driven by the motor 19, moves the chain 17, which in turn clamps the copper and aluminum busbars through the clamping mechanism 1, allowing the copper and aluminum busbars to sequentially enter the fluidized bed 14, thus completing the production process. Clamping mechanism 1 includes: Telescopic component 11 is slidably connected to the outer wall of the annular slide rail 18 via a telescopic member; The telescopic component includes a support plate 111 fixedly connected to the outer wall of the chain 17, and a telescopic rod 112 fixedly connected to the outer wall of the support plate 111. Clamping assembly 12 is fixedly connected to the outer wall of telescopic rod 112 via a protective component; The protective component includes a protective shell 121 that is fixedly connected to the end of the telescopic rod 112 away from the support plate 111; The telescopic component 11 drives the clamping component 12 to move, so that the clamped copper and aluminum busbars can be fully immersed in the fluidized bed 14.

[0023] Top block mechanism 2 includes: Switching component 21 is slidably connected to the inner wall of protective shell 121; Reset component 22 is fixedly connected to the outer wall of switching component 21; Among them, after the reset component 22 moves to the side close to the motor 19, it pushes the switching component 21 to change the state and change the clamping position of the clamping mechanism 1 on the copper-aluminum busbar.

[0024] Limiting mechanism 3 includes: Limiting component 31 is provided on the outer wall of the fixed platform 15; A number of assist components 32 are provided, and each of the assist components 32 is slidably connected to the top of the protective shell 121 via a pressing component; The pressing component includes a sliding column 321 that is slidably connected to the inner wall of the protective shell 121; The limiting component 31 is used to limit the position of the clamping component 12, and the assist component 32 is used to adjust the position of some parts of the clamping component 12.

[0025] Example 2, please refer to Figure 4 - Figure 11 The present invention is a copper-aluminum busbar insulation layer uniform coating device. Based on the first embodiment, the telescopic component 11 includes a slider 113 fixedly connected to the outer wall of the support plate 111, and the outer wall of the slider 113 is slidably connected to the annular slide rail 18. The chain 17 drives the slider 113 to slide on the outer wall of the annular slide rail 18, which in turn drives the clamping assembly 12 to move along the annular slide rail 18.

[0026] The clamping assembly 12 includes a plurality of fixing rods 122 fixedly connected to the inner wall of the protective shell 121. Two springs 123 are sleeved on the outer wall of each fixing rod 122. A plurality of clamping plates 124 are slidably connected to the outer wall of the fixing rods 122. A plurality of contact pins 125 are fixedly connected to the outer wall of each clamping plate 124. The clamping plates 124 are fixedly connected to the springs 123. Among them, several springs 123 are located between the clamping plate 124 and the protective shell 121. Several springs 123 on the side away from the annular slide rail 18 are initially in a free state, while several springs 123 on the side closer to the annular slide rail 18 are initially in a compressed state under the pressure of the switching component 21. Motor 19 drives fixed platform 15 to drive sprocket 16 to move. Support plate 111 fixedly connected to sprocket 16 starts to move along the moving direction of sprocket 16, driving telescopic rod 112 and protective shell 121 to move. During the movement of sprocket 16, the entire device also moves. At this time, limit rod 313 fixed to the outer wall of protective shell 121 extends. When the clamping device moves to a certain position, support shaft 211 contacts buffer slope on slide groove 312. Due to the height difference between fixed platform 15 and slide groove 312, support shaft 211 is raised to the height of fixed platform 15 through buffer slope. At this time, limit groove 311 pushes top block 212 to move. At this time, the widest point of top block 212 leaves the two clamping plates 124 on the side close to spring 222. The distance between the two clamping plates 124 becomes smaller, clamping the copper-aluminum busbar.

[0027] The switching component 21 includes a support shaft 211 that is slidably connected to the inner wall of the protective shell 121, and a top block 212 is fixedly connected to the side of the support shaft 211 away from the annular slide rail 18. Among them, the top block 212 is elliptical and is used to adjust the distance between the two clamping plates 124 on the side that are close to each other; The reset assembly 22 includes a limiting plate 221 fixedly connected to the outer wall of the support shaft 211, and a spring 222 sleeved on the outer wall of the support shaft 211. The outer wall of the spring 222 is fixedly connected to the outer wall of the limiting plate 221. Among them, spring 222 is located between limiting plate 221 and protective shell 121, and spring 222 is initially in a free state; When the support shaft 211 contacts the buffer slope and is raised, the widest point of the top block 212 is away from the two clamping plates 124. When the top block 212 enters the gap between the clamping plates 124, both pairs of clamping plates 124 are clamping the copper-aluminum busbar. As the top block 212 continues to advance, the widest point of the top block 212 contacts another pair of clamping plates 124. The two clamping plates 124 away from the second spring 222 clamp the copper-aluminum busbar, while the two clamping plates 124 close to the second spring 222 do not clamp the copper-aluminum busbar, thus completing the exchange of clamping and preventing the copper-aluminum busbar from falling off. Similarly, when the support shaft 211 contacts the other buffer slope, the exchange of clamping is successfully completed.

[0028] The limiting component 31 includes a limiting groove 311 formed on the outer wall of the fixed platform 15, a sliding groove 312 formed on the outer wall of the fixed platform 15, a limiting rod 313 fixedly connected to the outer wall of the protective shell 121, the limiting rod 313 being adapted to the limiting groove 311, and the end of the support shaft 211 away from the top block 212 contacting the inner wall of the sliding groove 312. The chute 312 is disconnected on the side near the fluidized bed 14, and a buffer slope is provided at the disconnection position. The support shaft 211 moves along the chute 312. During use, the limiting rod 313 will slide along the inner wall of the limiting groove 311. The limiting rod 313 enters the limiting groove 311. During subsequent movement, the height of the clamping device changes due to the change in the height of the limiting groove 311. The telescopic rod 112 is stretched under the action of the limiting rod 313, and the support shaft 211 is always adapted to the slide groove 312.

[0029] The assist component 32 includes a limiting plate 322 fixedly connected to the outer wall of the slide column 321, and two top plates 323 rotatably connected to the bottom of the slide column 321. Among them, the two top plates 323 are at an angle, and the ends of the two top plates 323 away from the sliding column 321 are respectively rotatably connected to the inner walls of the two clamping plates 124; First, the copper-aluminum busbar to be processed is heated. Then, the operator presses the slide column 321 to move the slide column 321 downward. At this time, the included angle of the two top plates 323 set on the slide column 321 increases, which causes the distance between the two clamping plates 124 to increase. The copper-aluminum busbar is placed between the two clamping plates 124. The slide column 321 is released to achieve the clamping of the copper-aluminum plate.

[0030] The method for using the equipment for uniformly coating copper-aluminum busbar insulation includes the following steps: S1: Equipment installation: Before use, ensure that the fluidized bed 14 is working properly and that the fluidized bed 14 is filled with rubber powder. Then, when using it, connect the power supply to the motor 19. S2: Manual feeding: The worker takes out the heated copper and aluminum busbars, presses the slide column 321, and puts the copper and aluminum busbars into the clamping assembly 12 to ensure that the copper and aluminum busbars are in a horizontal state and that the copper and aluminum busbars are clamped firmly. S3: Start the equipment: The sprocket 16 on the left side, driven by the motor 19, moves the chain 17, causing the copper and aluminum bars to enter the fluidized bed 14 in sequence, thus completing the production.

[0031] A specific application of this embodiment is as follows: Before use, the copper-aluminum busbar to be processed is heated. Then, the operator presses the sliding column 321, causing it to move downwards. At this time, the included angle between the two top plates 323 rotated on the sliding column 321 increases, causing the distance between the two clamping plates 124 to increase. The copper-aluminum busbar is placed between the two clamping plates 124. The sliding column 321 is released, and the two clamping plates 124 away from the second spring 222 clamp the copper-aluminum busbar. At this time, the distance between the two clamping plates near the second spring 222 is greater than the distance between the two clamping plates 124 clamping the copper-aluminum busbar. The motor 19 drives the fixed table 15 to move. As the sprocket 16 moves, the support plate 111 fixedly connected to the sprocket 16 begins to move along the direction of movement of the sprocket 16, driving the telescopic rod 112 and the protective shell 121 to move. During the movement of the sprocket 16, the entire device also moves. At this time, the limiting rod 313 fixed to the outer wall of the protective shell 121 moves to the turning point and enters the limiting groove 311. During the subsequent movement, due to the change in the height of the limiting groove 311, the height of the clamping device changes, and the telescopic rod 112 is stretched under the action of the limiting rod 313, allowing the copper and aluminum bars to enter the fluidized bed 14 and begin the powder dipping process. During the movement, the support shaft 211 is always matched with the slide 312. When the clamping device moves to a certain position, the support shaft 211 contacts the buffer slope on the slide 312. Due to the height difference between the fixed platform 15 and the slide 312, the support shaft 211 is raised to the height of the fixed platform 15 through the buffer slope. At this time, the limiting groove 311 pushes the top block 212 to move. At this time, the widest point of the top block 212 leaves the two clamping plates 124 on the side close to the second spring 222. The distance between the two clamping plates 124 becomes smaller, clamping the copper-aluminum busbar. During the continuous movement, the widest point of the top block 212 enters the two clamping plates 124 on the side away from the second spring 222. The distance between the two clamping plates 124 becomes larger, maintaining the state of not clamping the copper-aluminum busbar. After the support shaft 211 moves on the surface of the fixed platform 15 for a period of time, the powder immersion at the clamping position is completed. After the support shaft 211 enters another buffer slope, the state of the top block 212 returns to the original state, clamping the copper-aluminum busbar, so that the powder immersion of the clamping coverage point is completed during the powder immersion process. Taking advantage of the movement of the top block 212, a switching component 21 is installed inside the equipment. When the support shaft 211 contacts the buffer slope and the height is increased, the widest point of the top block 212 is away from the two clamping plates 124. When the top block 212 enters the gap between the clamping plates 124, both pairs of clamping plates 124 are clamping the copper and aluminum busbars. When the top block 212 continues to advance, the widest point of the top block 212 contacts another pair of clamping plates 124. The two clamping plates 124 away from the second spring 222 clamp the copper and aluminum busbars, while the two clamping plates 124 close to the second spring 222 do not clamp the copper and aluminum busbars, thus completing the exchange of clamping and preventing the copper and aluminum busbars from falling off. Similarly, when the support shaft 211 contacts another buffer slope, the exchange of clamping is successfully completed, preventing the copper and aluminum busbars from falling off or tilting during the exchange process. Utilizing the aforementioned feature of the limiting rod 313 adapting to the limiting groove 311, the clamped copper-aluminum busbar moves along the slide 312. At the corner of the slide 312, the height of the copper-aluminum busbar decreases and enters the fluidized bed 14. During the immersion process, due to the continuous movement of the chain 17, the clamping device moves at a uniform speed, causing the copper-aluminum busbar to move at a uniform speed within the fluidized bed 14. Furthermore, since the movement trajectory of the copper-aluminum busbar is semi-circular during the immersion process, the area swept by the copper-aluminum busbar in the fluidized bed is fan-shaped, reducing the void phenomenon generated during the immersion process and improving the uniformity of immersion. Utilizing the characteristic of spring 123 pushing clamping plate 124, a clamping assembly 12 is provided. During the clamping process, when spring 123 is in a free state, the distance between the two clamping plates 124 is less than the thickness of the copper-aluminum plate. Figure 6After clamping the copper-aluminum busbar, the four springs 123 on the left side change from a free state to a compressed state. At this time, the two clamping plates 124 exert opposing pressure on the copper-aluminum busbar, causing several contact pins 125 fixed on the clamping plates 124 to abut against the copper-aluminum busbar. In addition, several contact pins 125 on the two clamping plates 124 are misaligned and rotated, and the copper-aluminum busbar is slightly tilted during the clamping process, which improves the stability of the copper-aluminum busbar during the clamping process and reduces the probability of the copper-aluminum busbar shaking and falling off during the movement.
