Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a coating device for copper busbar preparation. Background Technology

[0002] In industrial sectors such as power transmission and electrical equipment manufacturing, copper busbars, as an important conductive connector, are widely used in various electrical installations such as transformers, switchgear, and distribution boxes due to their excellent conductivity, good mechanical strength, and outstanding heat dissipation. As industrial production increasingly demands higher performance from electrical equipment, the processing precision and surface quality of copper busbars have received increasing attention. Their surface condition directly affects the stability and safety of electrical connections, as well as the overall service life of the equipment.

[0003] In the actual production process of copper busbars, after a series of processing steps such as rolling, cutting, and bending, the copper busbars typically need to be transported from the production plant to the assembly workshop or a customer-designated location. Since copper busbars are mostly long and narrow, they are often stacked for storage and handling to improve space utilization and reduce transportation costs. However, this stacking method has significant technical drawbacks: the stacked copper busbars rub against each other due to bumps and vibrations during transport, easily causing scratches and wear on their surfaces. Once the surface of the copper busbar is worn, it not only damages its original smooth appearance but also seriously affects its performance. On the one hand, the reduced conductive cross-sectional area in the worn area leads to increased resistance when current flows, generating additional Joule heat, reducing power transmission efficiency, and potentially causing safety hazards due to localized overheating. On the other hand, the worn surface loses its original dense structure, making it more susceptible to corrosion from moisture, dust, and corrosive gases in the air, accelerating the oxidation and corrosion process and significantly shortening its service life.

[0004] To address the surface wear issue during copper busbar transportation, existing technologies typically employ a protective coating process. Current conventional coating methods involve covering the top and bottom surfaces of the copper busbar with a thin, durable plastic film to isolate it from direct contact with the external environment and reduce friction damage. However, this conventional method has significant limitations: it only protects the top and bottom surfaces, leaving the sides exposed during transport and stacking. In actual transport, these exposed sides inevitably collide and rub against adjacent busbars or the transport packaging, resulting in wear and scratches. This wear not only affects the busbar's appearance but can also lead to increased clearances with other components during assembly due to insufficient flatness, impacting electrical connection reliability. Furthermore, metal debris from side wear can enter electrical equipment, causing short circuits and other safety hazards, seriously jeopardizing the stable operation of the equipment.

[0005] Therefore, it is necessary to provide a coating equipment for copper busbar preparation to solve the above problems. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a coating device for copper busbar preparation, so as to solve the problems mentioned in the background technology.

[0008] Furthermore, a partition is installed in the middle of the frame, and several baffles are symmetrically arranged on both sides of the partition; The pressure-applying unit includes a housing fixedly connected to a baffle, a guide post, a ball bearing, and a spring. One end of the guide post has a placement groove, and the ball bearing is located within the placement groove. The outer peripheral wall of the guide post has a front protrusion and a rear protrusion, both located within the cavity of the housing. One end of the spring abuts against the rear protrusion, and the other end abuts against the bottom of the cavity of the housing.

[0009] Furthermore, the opening length of the placement groove is smaller than the diameter of the ball.

[0010] Furthermore, the top of the air outlet duct has an interface for connecting an air source, and the bottom has several air outlets along its length.

The equipment is equipped with an air outlet channel, which allows the excess roll film covering the corners of the copper busbar to be affected by the airflow and adhere to its perimeter. Through the contact between the roll film and the ball bearings, after pressure is applied, the adhesion between the side roll film and the copper busbar is strengthened, so as to coat and protect the side surface of the copper busbar. By setting the opening length of the placement groove to be smaller than the diameter of the ball, the ball can rotate freely, preventing it from falling off when it comes into contact with the side film roll. By incorporating a spring, a certain error is introduced when the guide post contacts the copper busbar. The spring causes the guide post to extend and retract, which increases the service life and avoids the phenomenon that the error cannot be adjusted after positioning.

The guide roller 9 is located between the attachment roller 7 and the roll film 10. The joint of the roll film 10 passes through the guide roller 9 and the attachment roller 7 in sequence and its width is greater than the width of the copper busbar. An air outlet channel 12 is installed at the top of the frame 1 along the direction of copper busbar movement. The air outlet channel 12 is used to blow airflow toward the roll film 10 attached to the copper busbar. Several elastically telescopic pressure units 6 are provided below both sides of the air outlet channel 12. When the copper busbar passes through the pressure units 6, the excess roll film 10 on both sides is pressed and covered by the pressure units 6.

[0019] A partition 11 is installed in the middle of the frame 1, and several baffles 5 are symmetrically arranged on both sides of the partition 11; The pressure unit 6 includes a housing 61 fixedly connected to the baffle 5, a guide post 62, a ball bearing 63, and a spring 64. One end of the guide post 62 is provided with a placement groove 621, and the ball bearing 63 is located in the placement groove 621. The outer peripheral wall of the guide post 62 has a front protrusion 622 and a rear protrusion 623 protruding outward. The front protrusion 622 and the rear protrusion 623 are both located in the cavity of the housing 61. One end of the spring 64 abuts against the rear protrusion 623, and the other end abuts against the bottom of the cavity of the housing 61.

[0020] The opening length of the placement groove 621 is smaller than the diameter of the ball 63.

[0021] The top of the air outlet duct 12 has an interface 121 for connecting an air source, and the bottom has several air outlets along its length.

[0022] The transmission unit includes two coaxially connected driven sprockets 2, two coaxially connected driving sprockets 3, and two conveyor chains 4. The two conveyor chains 4 are nested on the corresponding driven sprockets 2 and driving sprockets 3. Copper is placed on the top of the two conveyor chains 4. One end of the driving sprocket 3 is connected to a drive unit.

[0023] It also includes a cutting unit 8 located between the attachment roller 7 and the guide roller 9. The cutting unit 8 includes a mounting plate 81 fixedly connected to the frame 1. A driven wheel 82 and a driving wheel 83 are rotatably mounted on one side of the mounting plate 81. A conveyor belt 84 is sleeved on the driven wheel 82 and the driving wheel 83. A knife holder 85 is fixedly connected to the conveyor belt 84. The knife holder 85 is located between the driven wheel 82 and the driving wheel 83. A cutter 86 for cutting the roll film 10 is fixedly connected below the knife holder 85. A drive unit is drivenly connected to one end of the driving wheel 83.

[0024] In one embodiment, the working principle of the device

[0025] Specifically, the roll film 10 is installed on the top of the frame 1, the connector is taken out, passes around the guide roller 9 and then around the attachment roller 7, and the interface 121 is connected to the air source. The drive unit on the transmission unit is started, and the drive unit includes, but is not limited to, a motor. At this time, the drive sprocket 3 rotates and drives the conveyor chain 4 to rotate, and the copper busbar is placed on the conveyor chain 4. The copper busbar moves forward and passes through the guide roller 9. The guide roller 9 presses the roll film 10 onto the copper busbar. At this time, the copper busbar moves forward and drives 10 to move forward. The guide roller 9 rotates and the roll film 10 is unwound. Then it passes through the cutting unit 8. When it reaches the attachment roller 7, the attachment roller 7 presses the roll film 10 on the copper busbar. At this time, the airflow blown out of the air outlet 12 blows the excess roll film 10 on both sides to the sides of the copper busbar. After passing through the pressure unit 6, the ball 63 contacts the roll film 10 on the side and rolls on the roll film 10. The setting of the spring 64 makes the ball 63 better cooperate with the side of the copper busbar 10. When the tail of the coated copper busbar passes the attachment roller 7, the drive unit on the cutting unit 8 is activated. The drive unit includes, but is not limited to, a motor. The drive unit drives the drive wheel 83 to rotate, thereby rotating the conveyor belt 84 and driving the cutter holder 85 to move in a straight line. After the cutter 86 cuts the roll film 10, the drive unit is controlled to drive the drive wheel 83 to rotate in the opposite direction, so that the cutter holder 85 and the cutter 86 are reset. After being subjected to the airflow of the air outlet channel 12, the front and rear roll films 10 are also attached to the front and rear end faces of the copper busbar. At this time, the copper busbar is covered with roll film 10 all around. Then, the above steps are followed to coat the next copper busbar.

[0026] In summary, this device, by providing an air outlet channel 12, causes the excess film 10 covering the corners of the copper busbar to adhere to its perimeter under the influence of airflow. Through the contact between the film 10 and the ball bearing 63, pressure is applied, which strengthens the adhesion between the side film 10 and the copper busbar, thereby protecting the side surface of the copper busbar with a film. By setting the opening length of the placement groove 621 to be smaller than the diameter of the ball 63, the ball 63 can rotate freely, preventing the ball 63 from falling off when it comes into contact with the side roll film 10. By incorporating a spring 64, a certain error can be introduced when the guide post 62 contacts the copper busbar. The spring 64 causes the guide post 62 to extend and retract, which increases the service life and avoids the phenomenon that the error cannot be adjusted after positioning.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
