Description

Technical Field

[0001] The invention relates to the technical field of capacitor film production, in particular to a tape splicing device for capacitor film production. Background Art

[0002] Capacitance, also known as capacitance, refers to the storage of free charge under a given potential difference. Generally speaking, charges will move under force in an electric field. When there is a medium between conductors, the movement of charges is hindered and the charges accumulate on the conductors, resulting in the accumulation and storage of charges. The amount of stored charge is called capacitance. Capacitance refers to the ability to hold charge. Any electrostatic field is composed of many capacitors. Where there is an electrostatic field, there is capacitance. Capacitance is described by the electrostatic field. It is generally believed that an isolated conductor and infinity constitute a capacitor. Grounding a conductor is equivalent to connecting to infinity and connecting to the earth as a whole. At present, film materials are needed in the production process of capacitors. During the processing of capacitor films, the phenomenon of tape breakage is prone to occur. The commonly used method is manual tape splicing, which is less efficient. Therefore, a tape splicing device for capacitor film production is needed.

[0003] During the use of the existing splicing device for capacitor film production, wrinkles will appear on the film after the film breaks. If the wrinkled film is directly connected, the subsequent film will also be wrinkled, which will affect the quality of the subsequent film. At the same time, the stability of the film after splicing cannot be guaranteed. The spliced ​​film is prone to secondary breakage and local fracture during subsequent transportation, which will also affect the quality of the film.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing tape splicing devices for capacitor film production on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0045] The specific implementation of this embodiment is as follows: the film is transported by the first guide roller 14 and the second guide roller 2011, and passes through the bottom of the pressing plate 3111 and the moving frame 3101. When the film is broken, the films on both sides are placed between the bottom of the pressing plate 3111 and the moving frame 3101, and then the third cylinder 3110 is controlled to drive the lifting box 3109 to move downward, and the lifting box 3109 drives the scraper 3120 to move downward close to the film until it is close to the film, and then the double-axis motor 3117 can be controlled to drive the screw 3118 to rotate, and the rotation of the screw 3118 can drive the two screw sleeves 3119 to move away from each other, and the screw sleeves 3119 drive the two scrapers 31 20 move away from each other, and the scrapers 3120 move away from each other and move on the film to level the film. The scraper 3120 drives the adjusting rod 3121 to move until the adjusting rod 3121 contacts the adjusting block 3112. The scraper 3120 continues to move to drive the adjusting rod 3121 to move. The adjusting rod 3121 squeezes the adjusting block 3112 to drive the adjusting block 3112 to move downward. The adjusting block 3112 drives the pressing plate 3111 and the lifting rod 3113 to move downward. The lifting rod 3113 drives the pressing block 3116 to move downward and squeeze the first spring 3114 until the bottom of the pressing plate 3111 contacts the film, so that the leveled film can be pressed and fixed.

The lifting frame 2009 can drive the tooth plate 2006 to move downward through the cooperation of the sliding sleeve 2008. The downward movement of the tooth plate 2006 will drive the gear 2004 to rotate.

After the joining is completed, the output end of the third cylinder 3110 is controlled to move upward to release the pressing and fixing of the film, and the first cylinder 2010 is controlled to operate to drive the lifting frame 2009 to move upward. The lifting frame 2009 is moved upward through the sliding sleeve.

Through the cooperation of the adjustment mechanism 2, the two sides of the film can be quickly driven to contact, so that the two sides of the film can be quickly connected. By setting the limit opening 3124 and the limit slider 3125, the moving range of the limit block 3122 can be limited. By limiting the moving range of the limit block 3122, the moving range of the moving frame 3101 can be limited to prevent it from rotating.The cooperation of the limit block 3122, the limit plate 3123, the limit opening 3124 and the limit slider 3125 can ensure the stable movement of the moving frames 3101 on both sides. When the two moving frames 3101 are in contact, one end of the films on both sides is located between the two moving frames 3101. By controlling the operation of the second cylinder 3108, the first cutter 3105 can be driven to move to the right through the cooperation of the moving block 3107. The first cutter 3105 moves to the right and gradually approaches the fixed block 3106 to cut off the excess film. The two films are in contact with each other only in a part between the two first electric heating plates 3104. At this time, the first electric heating plate 3104 is controlled to be turned on to perform hot-melt bonding at the contact position between the two films. The films on both sides can be flattened before being connected, and then pressed to avoid wrinkles at the film connection, thereby avoiding wrinkles in the film later and improving the film quality.

[0047] As a further limitation of the present invention, the reinforcement unit 32 includes a lifting plate 3201 and two fourth cylinders 3202, the lifting plate 3201 is located at the bottom of the top plate 11, the bottom of the fourth cylinder 3202 is fixedly connected to the top plate 11, the bottom of the output end of the fourth cylinder 3202 passes through the top plate 11 and is fixedly connected to the lifting plate 3201, the lifting plate 3201 is T-shaped, the bottom of the lifting plate 3201 is fixedly connected to a second electric heating plate 3203, the bottom of the lifting plate 3201 and the front and rear sides of the second electric heating plate 3203 are fixedly connected to a second cutter 3204, by setting the second cutter 3204, it can be used to cut off excess film, and by setting the second electric heating plate 3203, the film used for reinforcement can be heated to connect with the connection between the two side films, thereby improving the stability of the two films after connection.

[0048] The bottom of the front and rear sides of the lifting plate 3201 are both provided with clamping plates 3205, and the top and bottom of the opposite sides of the two clamping plates 3205 are respectively provided with positioning plates 3206 and pulling blocks 3207. There are two positioning plates 3206, and a positioning rod 3208 is fixedly connected to the surface of the positioning plate 3206. The surface of the positioning rod 3208 is sleeved with a second spring 3209. The side of the positioning rod 3208 away from the positioning plate 3206 passes through the clamping plate 3205 and is fixedly connected to the lifting plate 3201. The surface of the pulling block 3207 is fixedly connected to the clamping plate 3205, and the surface of the second spring 3209 is fixedly connected to the positioning plate 3206 and the clamping plate 3205, respectively. By providing the clamping plate 3205, it can be used to clamp the film for reinforcement. By providing the second spring 3209, it can be used to drive the clamping plate 3205 to press the film. By providing the pulling block 3207, it is convenient for the user to pull the clamping plate 3205.

[0049] The specific implementation method of this embodiment is as follows: the user pulls the pull block 3207 to drive the clamping plate 3205 away from the lifting plate 3201, and then the film used for reinforcement can be placed under the second electric heating plate 3203, so that the front and rear ends of the film are placed between the clamping plate 3205 and the lifting plate 3201, and the pull block 3207 is released. At this time, the second spring 3209 is reset to drive the clamping plate 3205 to gradually approach the lifting plate 3201 to clamp and fix the film. When the films on both sides are connected through the first electric heating plate 3104, the fourth cylinder 3202 is controlled to operate to drive the lifting plate 3201 to move downward. After the top of the opposite side of the moving frame 3101 contacts with the two pressure plates 3111, a gap is left between them for the lifting plate 3201 to move up and down. The downward movement of the lifting plate 3201 will drive the reinforcing film to contact the connection between the films on both sides. At the same time, the second cutter 3204 moves downward and contacts with the moving frame 3101 to cut off excess film. Then, the first electric heating plate 3104 is controlled to turn on to hot-melt the reinforcing film to the connection between the films on both sides, thereby improving the stability of the film after splicing, avoiding breakage and local fracture at the subsequent film splicing, and improving the subsequent processing quality of the film.
