Description

Technical Field

[0001] This invention relates to the technical field of laminated busbars, specifically to a hot pressing forming method for high voltage-resistant laminated busbar insulation films. Background Technology

[0002] High-voltage withstand laminated busbar insulation film is a key insulating material structure used in laminated busbars. It typically consists of an insulating film layer (such as polyimide film PI, polyethylene terephthalate PET, etc.) and an adhesive layer (such as hot melt adhesive or thermosetting adhesive) coated on its surface. This type of insulation film needs to possess excellent electrical insulation properties, high voltage withstand characteristics (e.g., withstanding thousands of kilovolts of DC voltage), good flame retardancy, heat resistance (e.g., withstanding a temperature range of -269℃ to 280℃), and resistance to high and low temperature shock and damp heat aging. This ensures effective isolation of metal busbars (such as copper or aluminum busbars) at different potentials in converters, drivers, or battery modules in fields such as new energy vehicles, electric locomotives, and photovoltaic inverters, achieving efficient and stable power distribution. Hot pressing is the core process for manufacturing laminated busbars. Its necessity lies in the fact that by precisely controlling the temperature, pressure and time parameters, hot pressing can melt and flow the adhesive layer on the insulating film, forming a tight and firm interface bond with the surface of the metal busbar, thereby eliminating air bubbles or gaps, ensuring that the insulating film uniformly covers the busbar and fills microscopic unevenness, and achieving durable and reliable insulation protection.

[0003] With the rapid development of new energy, power electronics and other industries, laminated busbars, as a high-efficiency power distribution connection component, are increasingly widely used in converters, drivers and battery modules. High-voltage laminated busbar insulation film is the core material ensuring the insulation performance of the busbar. It is usually composed of a high-performance insulating substrate such as polyimide film and an adhesive layer coated on it. It needs to possess excellent electrical insulation, heat resistance and resistance to thermal shock. Hot pressing is a key process in the manufacture of laminated busbars. By precisely controlling temperature, pressure and time parameters, the adhesive on the insulation film melts and flows, bonding with the metal busbar. The current production method relies mainly on manual operation. Workers need to manually put the stacked busbars and insulating film into the hot press, start the equipment to complete the hot pressing, and then manually take out the finished product. This process is not only labor-intensive, but also poses safety risks such as burns and mechanical crushing to operators because the hot press involves a high temperature and high pressure environment. In addition, the efficiency of the handling after hot pressing is low. New busbars can only be moved and placed after the finished product is taken out, which causes intermittent stoppages in the production process and limits the improvement of overall efficiency.

[0004] To address the above issues, a hot pressing forming method for high voltage-resistant laminated busbar insulation film is proposed. Summary of the Invention

[0015] This invention also provides a hot-pressing forming method for high voltage-resistant laminated busbar insulation films, using the aforementioned apparatus for forming, and including the following steps: S1: First, stack the workpiece blanks to be hot-pressed on the lower mold; S2: Once the workpiece busbars are stacked, the servo motor A can be started. When it runs, it will drive the transmission gear to rotate. The transmission gear meshes with the movable gear, which drives the screw to rotate. The threaded sleeve that is threaded with the screw, under the constraint of the limit rod and the limit plate, drives the fixed rod and the lower mold to move horizontally, and accurately delivers them to the processing station directly below the inner cavity of the hot press body. S3: Then the hot press body can be started to perform hot pressing operation on the busbar; S4: After the hot pressing is completed and the machine has cooled for a certain period of time, the operator can drive the transmission gear of the servo motor A to rotate in the opposite direction, which will drive the lower mold to slide the front side of the hot press body of the mother panel after hot pressing. S5: When the mold slides to the bottom of the n-shaped plate, the hydraulic push rod will drive the n-shaped plate to move downward to the appropriate position. Then, the servo motor B will start running. When the servo motor B runs, it will drive the rotating gear to rotate. When the rotating gear rotates, it will drive the moving rack plates on both sides to move relative to each other. This will drive the clamping plates on both sides to move relative to each other through the adjacent moving rod, so that they can be inserted into the bottom of the busbar to clamp it and move it to the top. The operator can remove it during hot pressing, so as not to delay the efficiency of hot pressing. S6: After the hot-pressed busbar is clamped and removed, the lower mold will continue to move forward. In addition, when the threaded sleeve moves forward, it will also drive the movable plate and the push rod to move forward through the special-shaped connecting rod. When the push rod moves forward, it will push the trapezoidal block to move forward. When the sliding groove moves forward, it will drive the transmission rack plate to move forward and stretch the return spring. In addition, when the transmission rack plate moves forward, it will not drive the one-way gear to rotate. When the trapezoidal block moves to contact the triangular block, it will move downward under its limit and squeeze the telescopic spring. At this time, the trapezoidal block will move away from the push rod and move to the right to restore itself under the action of the return spring. At this time, it will drive the one-way gear to rotate. S7: When the one-way gear rotates, it will drive the reciprocating screw to rotate, and at this time the lower mold will also stop moving forward. When the reciprocating screw rotates, it will drive the screw nut to move to the left. When the screw nut moves to the left, it will drive the upper plate to move to the left through the L-shaped connecting rod, which can push the busbars placed on the U-shaped feeding plate onto the lower mold, which is conducive to the start of a new round of hot pressing operation. S8: Finally, by turning the knob, the operator can drive the reciprocating screw to rotate in the opposite direction, thereby restoring the feeding plate to its original position, making it convenient for the next feeding operation.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the cooperation of components such as vertical plate, screw, movable gear, transmission gear, servo motor A, threaded sleeve, limit plate, limit rod, straight plate and fixed rod, the lower mold can be driven to slide back and forth on the support platform to realize the feeding and unloading of the busbar. No manual operation is required, which reduces the workload of the staff and solves the problem of relying on manual handling and placement, which is not only labor-intensive, but also poses safety risks such as burns and mechanical crushing to the operators due to the high temperature and high pressure environment of the hot press.

[0017] 2. Through the cooperation of components such as the n-shaped plate, servo motor B, rotating gear, moving rack plate, connecting plate, limit telescopic rod, support plate, moving rod and clamping plate, the hydraulic push rod can be driven to lower the clamping plate when the busbar slides to the outside of the hot press body after the busbar is hot pressed. This achieves clamping and upward movement of the busbar, which is beneficial for the staff to pick up and put down the busbar in the future. At the same time, it is also beneficial for the pusher plate to push the busbar stacked on the U-shaped feeding plate onto the lower mold when the lower mold slides to the front of the support table, thus improving the efficiency of hot pressing the busbar.

[0018] 3. Through the cooperation of components such as the mounting plate, sliding groove, rectangular plate, sliding rod, return spring, trapezoidal block, push rod, movable plate, irregular connecting rod, triangular block, transmission rack plate, one-way gear, reciprocating screw, screw nut, feeding plate, and L-shaped connecting rod, the trapezoidal block can be pushed forward by the push rod through the irregular connecting rod when the lower mold slides forward. At this time, the transmission gear will also move forward synchronously, but it cannot drive the one-way gear to rotate. When the trapezoidal block moves forward and contacts the triangular block, it will be driven to move downward by the extension spring, thus moving away from the push rod. At this time, the lower mold will also stop running. In addition, the transmission rack plate will also move backward under the action of the return spring, and drive the reciprocating screw to rotate through the one-way gear. This pushes the busbar placed on the U-shaped feeding plate onto the lower mold through the feeding plate. There is no need for the operator to remove the hot-pressed busbar and bring in a new busbar, which effectively improves the hot pressing rate of the busbar insulation film.

[0034] This invention also provides a hot-pressing forming method for high voltage-resistant laminated busbar insulation films, using the aforementioned apparatus for forming, and including the following steps: S1: First, stack the workpiece blanks to be hot-pressed on the lower mold 4; S2: After the workpiece busbars are stacked, the servo motor A55 can be started. When it runs, it will drive the transmission gear 54 to rotate. The transmission gear 54 meshes with the movable gear 53, which drives the screw 52 to rotate. The threaded sleeve 56, which is threaded with the screw 52, ​​drives the fixed rod 57 and the lower mold 4 to move horizontally under the constraint of the limit rod 562 and the limit plate 561, and accurately delivers them to the processing station directly below the inner cavity of the hot press body 1. S3: Then the hot press body 1 can be started to perform hot pressing operation on the busbar; S4: After hot pressing is completed and cooling for a certain period of time, the operator can drive the transmission gear 54 to rotate in the opposite direction using the servo motor A55, which will drive the lower mold 4 to slide the front side of the hot press body 1 of the mother busbar after hot pressing. S5: When the current mold 4 slides to the bottom of the n-shaped plate 71, the operation of the hydraulic push rod 6 will drive the n-shaped plate 71 to move downward to the appropriate position. Then, the servo motor B72 will start running. When the servo motor B72 runs, it will drive the rotating gear 73 to rotate. When the rotating gear 73 rotates, it will drive the moving rack plates 74 on both sides to move relative to each other. This will drive the clamping plates 76 on both sides to move relative to each other through the adjacent moving rod 75, so that they can extend into the bottom of the busbar, clamp it and move it to the top. The operator can remove it during hot pressing, so as not to delay the efficiency of hot pressing. S6: After the hot-pressed busbar is clamped and removed, the lower mold 4 will continue to move forward. In addition, when the threaded sleeve 56 moves forward, it will also drive the movable plate 932 and the push rod 931 to move forward through the irregular connecting rod 933. When the push rod 931 moves forward, it will push the trapezoidal block 93 to move forward. When the sliding groove 92 moves forward, it will drive the transmission rack plate 94 to move forward and stretch the return spring 923. In addition, when the transmission rack plate 94 moves forward, it will not drive the one-way gear 95 to rotate. When the trapezoidal block 93 moves to contact the triangular block 934, it will move downward under its limit and squeeze the telescopic spring. At this time, the trapezoidal block 93 will move away from the push rod 931, and thus move to the right to restore itself under the action of the return spring 923. At this time, it will drive the one-way gear 95 to rotate. S7: When the one-way gear 95 rotates, it will drive the reciprocating screw 96 to rotate, and at this time the lower mold 4 will also stop moving forward. When the reciprocating screw 96 rotates, it will drive the screw nut 97 to move to the left. When the screw nut 97 moves to the left, it will drive the upper plate 98 to move to the left through the L-shaped connecting rod 981, which can push the stacked busbars placed on the U-shaped feeding plate 8 to the lower mold 4, which is conducive to the start of a new round of hot pressing operation. S8: Finally, by turning knob 962, the operator can drive the reciprocating screw 96 to rotate in the opposite direction, thereby causing the feeding plate 98 to return to its original position, making it convenient for the next feeding operation.

[0035] Working principle: First, the workpiece blanks to be hot-pressed are stacked on the lower mold 4. After the workpiece blanks are stacked, the servo motor A55 is started. During operation, it drives the transmission gear 54 to rotate. The transmission gear 54 meshes with the movable gear 53, driving the screw 52 to rotate. The threaded sleeve 56, which is threaded with the screw 52, ​​drives the fixed rod 57 and the lower mold 4 to move horizontally under the constraint of the limit rod 562 and the limit plate 561, accurately sending it to the processing station directly below the inner cavity of the hot press body 1. Then, the hot press body 1 can be started. The busbar can then undergo hot pressing. After hot pressing and cooling for a certain period of time, the operator can drive the transmission gear 54 to rotate in the reverse direction using the servo motor A55. This will cause the lower mold 4 to slide along the front side of the hot press body 1 of the busbar after hot pressing. When the lower mold 4 slides to below the n-shaped plate 71, the operation of the hydraulic push rod 6 will move the n-shaped plate 71 downward to a suitable position. Then, the servo motor B72 will be started. When the servo motor B72 is running, it will drive the rotating gear 73 to rotate. When the rotating gear 73 rotates... This will cause the moving rack plates 74 on both sides to move relative to each other, thereby driving the clamping plates 76 on both sides to move relative to each other through the adjacent moving rod 75, thus extending into the bottom of the busbar to clamp it and move it upwards. The operator can remove it during hot pressing, thus not delaying the efficiency of hot pressing. After the hot-pressed busbar is clamped and removed, the lower mold 4 will continue to move forward. In addition, when the threaded sleeve 56 moves forward, it will also drive the movable plate 932 and the push rod 931 to move forward through the special connecting rod 933. When moving forward, the trapezoidal block 93 will be pushed forward. When the sliding groove 92 moves forward, it will drive the transmission rack plate 94 to move forward and stretch the return spring 923. In addition, when the transmission rack plate 94 moves forward, it will not drive the one-way gear 95 to rotate. When the trapezoidal block 93 moves to contact the triangular block 934, it will move downward under its limit and squeeze the telescopic spring. At this time, the trapezoidal block 93 will move away from the push rod 931, and thus move to the right to restore its original position under the action of the return spring 923. At this time, it will drive the one-way gear 95 to rotate.

10. A hot-pressing forming method for a high voltage-resistant laminated busbar insulation film, characterized in that, The hot pressing forming apparatus for a high voltage withstand laminated busbar insulation film according to any one of claims 1-9, wherein the forming process includes the following steps: S1: First, place the workpiece blank to be hot-pressed on the lower mold (4); S2: After the workpiece busbar is stacked, the servo motor A (55) can be started. When it runs, it will drive the transmission gear (54) to rotate. The transmission gear (54) meshes with the movable gear (53) and drives the screw (52) to rotate. The threaded sleeve (56) that is threaded with the screw (52) drives the fixed rod (57) and the lower mold (4) to move horizontally under the constraint of the limiting rod (562) and the limiting plate (561), and accurately delivers it to the processing station directly below the inner cavity of the hot press body (1). S3: Then the hot press body (1) can be run to perform hot pressing on the busbar; S4: After the hot pressing is completed and the machine has cooled for a certain period of time, the operator can drive the transmission gear (54) to rotate in the opposite direction using the servo motor A (55), which will drive the lower mold (4) to slide the front side of the hot press body (1) of the mother busbar after hot pressing. S5: When the current mold (4) slides to the bottom of the n-shaped plate (71), the operation of the hydraulic push rod (6) will drive the n-shaped plate (71) to move down to the appropriate position. Then, the servo motor B (72) will start running. When the servo motor B (72) runs, it will drive the rotating gear (73) to rotate. When the rotating gear (73) rotates, it will drive the moving rack plate (74) meshing with it on both sides to move relative to each other. Thus, the adjacent moving rod (75) will drive the clamping plate (76) on both sides to move relative to each other, thereby extending into the bottom of the busbar, realizing clamping and moving it to the top. The staff can take it away during hot pressing, so as not to delay the efficiency of hot pressing. S6: When the hot-pressed busbar is clamped and removed, the lower mold (4) will continue to move forward. In addition, when the threaded sleeve (56) moves forward, it will also drive the movable plate (932) and the push rod (931) to move forward through the shaped connecting rod (933). When the push rod (931) moves forward, it will push the trapezoidal block (93) to move forward. When the sliding groove (92) moves forward, it will drive the transmission rack plate (94) to move forward and stretch the return spring (923). In addition, when the transmission rack plate (94) moves forward, it will not drive the one-way gear (95) to rotate. When the trapezoidal block (93) moves to contact the triangular block (934), it will move downward under its limit and squeeze the telescopic spring. At this time, the trapezoidal block (93) will move away from the push rod (931) and move to the right to restore under the action of the return spring (923). At this time, it will drive the one-way gear (95) to rotate. S7: When the one-way gear (95) rotates, it will drive the reciprocating screw (96) to rotate, and at this time the lower mold (4) will also stop moving forward. When the reciprocating screw (96) rotates, it will drive the screw nut (97) to move to the left. When the screw nut (97) moves to the left, it will drive the upper plate (98) to move to the left through the L-shaped connecting rod (981). This will push the busbars stacked on the U-shaped feeding plate (8) to the lower mold (4), which is conducive to the development of a new round of hot pressing operations. S8: Finally, by turning the knob (962), the staff can drive the reciprocating screw (96) to rotate in the opposite direction, thereby driving the feeding plate (98) to return to its original position, so as to facilitate the next feeding operation.
