Description

Technical Field

[0001] The invention belongs to the technical field of capacitor film production, and in particular relates to a pressing device for composite capacitor film production. Background Art

[0002] Composite capacitors are widely used in power electronic equipment and energy storage systems due to their high capacitance, high energy density and excellent electrical properties. Films are the key material for composite capacitors. During the production process, polymers and electrode materials at different levels need to be precisely pressed together to ensure the performance and stability of the capacitor.

[0003] When pressing aluminum foil and polypropylene film into capacitor film, the prior art usually requires workers to stack the aluminum foil and polypropylene film and place them on top of a pressing device, and then use the pressing device to press the aluminum foil and polypropylene film. However, in the process of placing the aluminum foil and polypropylene film on the pressing device, workers need to cut the aluminum foil and polypropylene film into the same size, and then lay the aluminum foil flat first, and then lay the polypropylene film flat on the upper surface of the aluminum foil so that the aluminum foil and the polypropylene film can overlap, and then press them together. The steps are cumbersome, which reduces the efficiency of pressing the aluminum foil and the polypropylene film. At the same time, when placing the aluminum foil and the polypropylene film, workers cannot effectively remove the air between the aluminum foil and the polypropylene film, which will cause bubbles to be generated between the aluminum foil and the polypropylene film. The bubbles will form an air gap between the aluminum foil and the polypropylene film, which will cause the joint surfaces to be unable to fully contact, thereby reducing the joint strength, and also affecting the dielectric properties of the capacitor, resulting in a decrease in the capacitor's withstand voltage and an increase in leakage current.

[0020] Specifically, the polypropylene film and the aluminum foil can be automatically removed from the corresponding winding drums, so that the polypropylene film and the aluminum foil can be laid flat on the first heating plate 3, avoiding the manual laying method of the staff, which leads to reduced pressing efficiency. At the same time, in the process of automatically placing the polypropylene film and the aluminum foil, the air between the aluminum foil and the polypropylene film can be effectively removed to prevent bubbles from being generated between the aluminum foil and the polypropylene film, which causes the bubbles to form an air gap between the aluminum foil and the polypropylene film, making it impossible for the joint surfaces to be fully contacted, reducing the joint strength and the dielectric properties of the capacitor, and greatly improving the pressing efficiency and reliability of the device when pressing the polypropylene film and the aluminum foil.

[0021] In the embodiment, the dust collection assembly 13 includes a sixth electric telescopic rod 131 fixedly connected to the inner wall of the third groove 12, the telescopic ends of the sixth electric telescopic rod 131 are fixedly connected to a connecting plate 132, the top side wall of the connecting plate 132 is fixedly connected to a seventh electric telescopic rod 133, the telescopic end of the seventh electric telescopic rod 133 is rotatably connected to a round rod 134, and the rod wall of the round rod 134 is fixedly connected to a collection shell 135; The top side wall of the connecting plate 132 is fixedly connected with a support rod 136, one end of the support rod 136 is rotatably connected to the bottom side wall of the collecting shell 135, one end side wall of the collecting shell 135 is fixedly connected with a first air pump 137, the air inlet end of the first air pump 137 passes through the side wall of the collecting shell 135 and extends inwardly, and a plurality of ash suction holes 138 are provided on the top side wall of the collecting shell 135.

[0022] Specifically, in the process of taking the aluminum foil and the polypropylene film out of the winding drum, the corresponding seventh electric telescopic rod 133 is controlled to start. Since one end of the support rod 136 is rotatably connected to the bottom end of the collecting shell 135, as the seventh electric telescopic rod 133 is started, the collecting shell 135 will be driven to rotate around the support rod 136, so that the inclination angle of the collecting shell 135 matches the angle of the polypropylene film or the aluminum foil when it is released. Then, the sixth electric telescopic rod 131 is controlled to start, so that the upper surface of the collecting shell 135 contacts the lower surface of the polypropylene film or the aluminum foil. Then, the first air pump 137 is controlled to start, and the dust on the lower surface of the polypropylene film or the aluminum foil is sucked into the collecting shell 135 through the dust suction hole 138, so as to prevent the dust on the surface of the polypropylene film or the aluminum foil from affecting the pressing of the polypropylene film and the aluminum foil, thereby improving the use effect of the device.

[0023] In the embodiment, four eighth grooves 16 are symmetrically provided on the top side wall of the base plate 1, and the bottom inner walls of the eighth grooves 16 are fixedly connected with the eleventh electric telescopic rod 17, and the telescopic ends of the eleventh electric telescopic rod 17 are fixedly connected with the shell 18, and the top side wall of the shell 18 is rotatably connected with the connecting block 19, and the bottom inner wall of the shell 18 is fixedly connected with the third motor 20, and the output end of the third motor 20 passes through the side wall of the shell 18 and is fixedly connected with the bottom side wall of the connecting block 19, and the bottom side wall of the connecting block 19 is fixedly connected with the twelfth electric telescopic rod 21, and the telescopic end of the twelfth electric telescopic rod 21 is fixedly connected with the third clamping plate 22.

[0024] Specifically, the two eleventh electric telescopic rods 17 on one side of the polypropylene film winding drum are controlled to start, driving the housing 18 to move upward, so that the connecting block 19 extends out from the eighth groove 16, and then the third motor 20 is controlled to start, driving the connecting block 19 to rotate 90 degrees. At this time, the connecting block 19 is located above the polypropylene film, and then the twelfth electric telescopic rod 21 is controlled to start, and one end of the polypropylene film is fixed by the third clamping plate 22, so that the air between the polypropylene film and the aluminum foil can be squeezed out by the rotating tube 156 and the pressing plate 1515 to prevent bubbles from being generated during bonding.

[0025] The operating principle of the present invention is now described as follows: In the present invention, when it is necessary to press aluminum foil and polypropylene film into capacitor film, the staff firstly sleeves the winding drums for winding aluminum foil and polypropylene on the outside of two fixed rods 6 respectively, then controls the first electric telescopic rod 7 to start, drives the first clamping plate 8 to move, and uses the first clamping plate 8 to fix the two winding drums for winding aluminum foil and polypropylene, then controls the first electric slide rail 111 to start, so that the first slide plate 112 drives the U-shaped plate 155 to move to the direction of the aluminum foil winding drum, and then the staff puts one end of the aluminum foil into the two clamping plates 115. In this process, the first motor 5 is controlled to start, and drives the fixed rod 6 for fixing the aluminum foil winding drum to rotate, so that the staff can remove one end of the aluminum foil from the winding drum, and then put one end of the aluminum foil into the two clamping plates 115, the fifth electric telescopic rod 116 is controlled to start, driving the second clamping plate 117 to move, and one end of the aluminum foil is fixed by the second clamping plate 117, and then the first electric slide rail 111 is controlled to start, driving the second clamping plate 117 to move, and at the same time, the corresponding first motor 5 is controlled to drive the winding drum to rotate, so that the length of the aluminum foil released matches the moving speed of the second clamping plate 117. After one end of the aluminum foil is moved to the side of the first heating plate 3, the second electric slide rail 151 is controlled to start, driving the second slide plate 152 to move, so that the U-shaped plate 155 is located above one side of the aluminum foil, and then the eighth electric telescopic rod 154 is controlled to start, so that the rotating tube 156 contacts the surface of the aluminum foil, and then the second electric slide rail 151 is controlled to start again, driving the rotating tube 15 6 moves, during the movement of the rotating tube 156, the second motor 157 is controlled to start, driving the rotating tube 156 to rotate in the moving direction of the rotating tube 156. After the rotating tube 156 moves a certain distance, the ninth electric telescopic rod 1514 is controlled to start, so that the pressing plate 1515 contacts the upper surface of the aluminum foil. Since the pressing plate 1515 and the rotating tube 156 are both in contact with the upper surface of the aluminum foil during the movement, as the pressing plate 1515 and the rotating tube 156 move, the corresponding first motor 5 is controlled to start, so that the aluminum foil reel continues to release the aluminum foil, and matches the moving speed of the pressing plate 1515 and the rotating tube 156, so as to prevent the pressing plate 1515 and the rotating tube 156 from causing pressure on the aluminum foil during the movement and causing it to break. The movement will make the lower surface of the aluminum foil completely fit with the upper surface of the first heating plate 3, and the air between the aluminum foil and the first heating plate 3 will be discharged. At the same time, the rotation of the rotating tube 156 is used to squeeze the aluminum foil downward so that the aluminum foil and the first heating plate 3 are fitted together. During the rotation of the rotating tube 156, the second air pump 158 is controlled to start and the air in the rotating tube 156 is extracted. After the boss 1513 contacts the surface of the aluminum foil, the boss 1513 is squeezed inward. At this time, the pressure sensor 1511 detects the pressure, indicating that the boss 1513 is in contact with the surface of the aluminum foil. After the rotating tube 156 continues to rotate for 15 degrees, a group of solenoid valves 159 corresponding to the pressure sensor 1511 are controlled to open. At this time, since the second air pump 158 is working,The dust on the upper surface of the aluminum foil will be sucked into the rotating tube 156 through the opened electromagnetic valve 159 to prevent the subsequent placement of the polypropylene film on the upper surface of the aluminum foil, and the dust will be mixed in between, which will affect the pressing of the aluminum foil and the polypropylene film. After the pressing plate 1515 moves to the top of the cutter 1517, the second electric slide rail 151 is controlled to close, and then the tenth electric telescopic rod 1516 is controlled to start, driving the cutter 1517 to move upward to cut the aluminum foil so that the size of the aluminum foil matches the size of the first heating plate 3. At this time, the placement of the aluminum foil is completed, and then the fifth electric telescopic rod 116 is controlled to restore the original position, and at the same time the fourth electric telescopic rod 114 is controlled to drive the card plate 115 upward for a distance, so that the card plate 115 does not contact the aluminum foil during the subsequent movement, so as to prevent the aluminum foil from being pressed. After that, one end of the polypropylene film is put into the card plate 115, and the first electric slide rail 111 and the corresponding first motor 5 are controlled to start according to the above steps to remove the polyethylene film from the winding drum. After one end of the polyethylene film is moved to one end of the upper surface of the first heating plate 3, the second electric slide rail 151 is controlled to start, and the second slide plate 152 is driven to move toward the polypropylene winding drum. According to the above steps, the polypropylene film and the aluminum foil are bonded together, and the air between the polypropylene film and the aluminum foil is squeezed out to prevent bubbles from being generated during bonding. The rotating tube 156 and the second air pump 158 are used to suck away the dust on the upper surface of the aluminum foil to prevent the dust from blocking the surface of the second heating plate 93 when the aluminum foil and the polypropylene film are pressed together, thereby affecting the bonding between the aluminum foil and the polypropylene film. The polypropylene film is pressed together. After the corresponding cutter 1517 is controlled to cut the polypropylene film according to the above steps, the second electric slide rail 151 is controlled to move in the opposite direction. Then, the two eleventh electric telescopic rods 17 on one side of the polypropylene film winding drum are controlled to start, driving the housing 18 to move upward, so that the connecting block 19 extends out from the eighth groove 16. Then, the third motor 20 is controlled to start, driving the connecting block 19 to rotate 90 degrees. At this time, the connecting block 19 is located above the polypropylene film. Then, the twelfth electric telescopic rod 21 is controlled to start, and one end of the polypropylene film is fixed by the third clamping plate 22. At the same time, the fifth electric telescopic rod 116 is controlled to restore its original position, and the first electric slide rail 111 is controlled to start, driving the first slide plate 112 to move to the most Initial position, at this time, the rotating tube 156 and the pressing plate 1515 will move to the position where the second clamping plate 117 clamps the polypropylene film, so as to discharge the air at the bottom of the clamping position of the polypropylene film, so that no bubbles are generated between the polypropylene film and the aluminum foil, and then the two eleventh electric telescopic rods 17 on the other side are controlled to start, and the other end of the polypropylene film is fixed by the third clamping plate 22 according to the above steps, and the second slide rail is controlled to start at the same time, so that the second slide plate 152 moves to the initial position, and then the second electric telescopic rod 92 is controlled to start, driving the second heating plate 93 to move downward, and when there is still a distance from the polypropylene film, the third electric telescopic rod 95 is controlled to start, driving the third heating plate 96 to move downward, and the four corners of the polypropylene film are fixed.At the same time, the third motor 20 is controlled to rotate 90 degrees in the opposite direction, and the twelfth electric telescopic rod 21 is controlled to restore to its original position, and then the eleventh electric telescopic rod 17 is controlled to restore to its original position, and then the second electric telescopic rod 92 is controlled to drive the second heating plate 93 to continue to move downward. During the movement, the third electric telescopic rod 95 is controlled to contract, and the contraction speed of the third electric telescopic rod 95 can make the third heating plate 96 always contact with the upper surface of the polypropylene film, so as to fix the polypropylene film, and then the second heating plate 93 is driven downward by the second electric telescopic rod 92 to press the polypropylene film and the aluminum foil, so as to produce a capacitor film, which can It can automatically remove the polypropylene film and the aluminum foil from the corresponding winding drum, so that the polypropylene film and the aluminum foil can be laid flat on the first heating plate 3, avoiding the manual laying method of the staff, which leads to reduced lamination efficiency. At the same time, it can effectively remove the air between the aluminum foil and the polypropylene film in the process of automatically placing the polypropylene film and the aluminum foil, and prevent the generation of bubbles between the aluminum foil and the polypropylene film, which causes the bubbles to form an air gap between the aluminum foil and the polypropylene film, making it impossible for the joint surface to be fully in contact, reducing the joint strength and the dielectric properties of the capacitor, and greatly improving the lamination efficiency and reliability of the device when laminating the polypropylene film and the aluminum foil.
