Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil slitting technology, specifically to a slitting device for electrolytic copper foil. Background Technology

[0002] Electrolytic copper foil, as one of the fundamental materials in the electronics industry, occupies a pivotal position in the electronic information industry. With the rapid development of electronic technology in recent years, especially the booming development of smartphones, tablets, new energy vehicles, and 5G communications, the demand for electrolytic copper foil has experienced explosive growth. Due to its excellent electrical conductivity, thermal conductivity, and ductility, electrolytic copper foil is widely used in printed circuit boards (PCBs), lithium-ion batteries, and other fields. In the PCB field, electrolytic copper foil is a key material for making the conductive layer of the circuit board, and its quality directly affects the performance and reliability of the circuit board. In the lithium-ion battery field, electrolytic copper foil, as the negative electrode current collector, plays a crucial role in the battery's capacity, charge-discharge efficiency, cycle life, and other performance indicators.

[0003] Electrolytic copper foil is conveyed by multiple conveying rollers to a slitting roller, which then cuts the entire electrolytic copper foil into several strips. Finally, a winding roller rewinds the electrolytic copper foil.

[0004] Although the above equipment can cut electrolytic copper foil, there is airflow in the production workshop, such as fan blowing and air conditioning exhaust. The airflow will exert a lateral thrust on the electrolytic copper foil, causing the copper foil to deviate. This effect is more obvious when the copper foil is thin and light. Once the electrolytic copper foil deviates, it will not only affect the cutting accuracy, but may also cause defects such as wrinkles and tears on the edges of the copper foil, reducing the product qualification rate. Utility Model Content

[0005] In view of this, the present invention provides a slitting device for electrolytic copper foil. The present invention can make one side of the groove on the two anti-deviation blocks flush with the side end of the electrolytic copper foil, thereby avoiding the phenomenon of deviation of the electrolytic copper foil during the conveying and slitting process.

[0006] To solve the above-mentioned technical problems, this utility model provides a slitting device for electrolytic copper foil, including a support base one and a support base two. A slitting roller and a conveying roller are rotatably arranged between the support base one and the support base two, respectively. The conveying roller is located at the bottom of the slitting roller, and a slitting blade is arranged on the slitting roller. Mounting blocks are arranged on both the support base one and the support base two. An adjustment component is arranged between the mounting blocks. The adjustment component includes a sliding column arranged between the mounting blocks. Two anti-deviation blocks are slidably arranged on the sliding column. The two anti-deviation blocks are provided with grooves. That is, firstly, during the conveying process of electrolytic copper foil, the operator manually adjusts the distance between the two anti-deviation blocks according to the width of the electrolytic copper foil to be slid, so that the two ends of the electrolytic copper foil contact the grooved sides of the two anti-deviation blocks, thereby avoiding the phenomenon of deviation of the electrolytic copper foil during the conveying process.

[0007] The adjustment assembly also includes a bidirectional lead screw disposed between the mounting blocks, which passes through the interior of the two anti-displacement blocks; that is, the bidirectional lead screw can adjust the distance between the two anti-displacement blocks, thereby accommodating electrolytic copper foils of different sizes.

[0008] The adjustment assembly also includes a drive button 1 located on one end of the mounting block, which is fixedly connected to one end of the bidirectional lead screw; that is, the drive button 1 can drive the bidirectional lead screw.

[0009] The adjustment assembly also includes a threaded rod rotatably mounted on the top of the two anti-deviation blocks. A fixed frame is set in the groove, and the tail end of the threaded rod is connected to the top of the fixed frame. A roller is set on the fixed frame, and a drive button is set at the head end of the threaded rod. The drive button can drive the threaded rod to rotate, causing the fixed frame to slide down in the groove, so that the roller contacts the electrolytic copper foil, thereby preventing the electrolytic copper foil from loosening during the transportation process.

[0010] Gear 1 and Gear 2 are respectively provided on the side end of support base 2. One side of gear 1 is connected to one end of the slitting roller, and one side of gear 2 is connected to one end of the conveying roller. Gear 1 and Gear 2 are meshed; that is, gear 1 can provide transmission for gear 2, so that the conveying roller and the slitting roller rotate relative to each other.

[0011] A protective shell is provided on the side end of the support base two. The protective shell is located on the outer surface of gear one and gear two; that is, the protective shell provides protection for gear one and gear two, thereby preventing dust from entering.

[0012] A motor is mounted on the protective casing, and the output shaft of the motor is connected to the side end of gear one; that is, the motor provides driving force to gear one.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. First, drive a pair of bidirectional lead screws to rotate via the drive button, so that the external thread of the bidirectional lead screws contacts the internal threads of the two anti-displacement blocks. As the bidirectional lead screws are rotated, the two anti-displacement blocks move or separate from each other, so that the grooves on the two anti-displacement blocks can control the width between the electrolytic copper foils.

[0015] 2. By driving the threaded worm gear, the fixed frame moves downward, so that the rollers come into contact with the electrolytic copper foil, thereby providing a pressing effect on the electrolytic copper foil and preventing the electrolytic copper foil from loosening during the transportation process.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-3As shown: This embodiment provides a slitting device for electrolytic copper foil, including a first support base 100 and a second support base 101. The first support base 100 and the second support base 101 are bolted to the slitting machine body. A slitting roller 102 and a conveying roller 103 are rotatably arranged between the first support base 100 and the second support base 101, respectively. The conveying roller 103 is located at the bottom of the slitting roller 102. A slitting blade is provided on the slitting roller 102. At the same time, the conveying roller 103 can provide a conveying function for the electrolytic copper foil. Mounting blocks 108 are provided on both the first support base 100 and the second support base 101. The mounting blocks 108 are fixedly installed on the first support base 100 and the second support base 101 by welding. An adjustment assembly 200 is provided between the mounting blocks 108. The adjustment assembly 200 includes a sliding column 202 disposed between the mounting blocks 108. The sliding column 202 is fixedly mounted on the mounting blocks 108 by welding. Two anti-deviation blocks 204 are slidably disposed on the sliding column 202. The two anti-deviation blocks 204 are provided with grooves 209 to limit the electrolytic copper foil sheet during the conveying process, so that both ends of the electrolytic copper foil sheet are located between the two anti-deviation blocks 204. By moving the two anti-deviation blocks 204 on the sliding column 202, one side of the groove 209 on the two anti-deviation blocks 204 is flush with the side end of the electrolytic copper foil sheet, thereby avoiding the phenomenon of deviation of the electrolytic copper foil sheet during the conveying and cutting process.

[0024] When the electrolytic copper foil moves to the position of the slitting roller 102, the slitting blades installed on the slitting roller 102 will cut the electrolytic copper foil. At the same time, in order to prevent the electrolytic copper foil from shifting during the conveying and cutting process, which would affect the cutting quality and product accuracy, the operator manually moves two anti-shift blocks 204 to slide on the slide column 202 according to the width of the electrolytic copper foil, adjusting the distance between the two anti-shift blocks 204 so that both ends of the electrolytic copper foil are located in the grooves 209 of the two anti-shift blocks 204 respectively, and one side of the groove 209 is flush with the side end of the electrolytic copper foil. During the entire process of conveying and cutting the electrolytic copper foil, the anti-shift blocks 204 can play a limiting role, effectively preventing the electrolytic copper foil from shifting, ensuring that the cutting work can be carried out stably and accurately, and ensuring that the cut electrolytic copper foil meets the quality requirements.

[0025] Adjustment component 200, such as Figure 1 As shown,

[0026] The adjustment assembly 200 also includes a bidirectional lead screw 203 disposed between the mounting blocks 108. The bidirectional lead screw 203 can rotate between the mounting blocks 108. The bidirectional lead screw 203 passes through the interior of the two anti-displacement blocks 204, so that the external thread of the bidirectional lead screw 203 contacts the internal thread of the two anti-displacement blocks 204. As the bidirectional lead screw 203 is rotated, the two anti-displacement blocks 204 move relative to each other or separate from each other.

[0027] The adjustment assembly 200 also includes a drive button 201 disposed on one end of the mounting block 108. The drive button 201 is fixedly disposed on one end of the bidirectional lead screw 203. The drive button 201 is fixedly installed on one end of the bidirectional lead screw 203, thereby facilitating the rotation of the bidirectional lead screw 203 by personnel.

[0028] Threaded rod 206 Figure 2 As shown,

[0029] The adjusting assembly 200 also includes a threaded rod 206 rotatably mounted on the top of the two anti-deviation blocks 204, which facilitates the connection of the threaded rod 206 with the threaded hole on the top of the anti-deviation block 204. A fixed frame 207 is slidably mounted in the groove 209. The side end of the fixed frame 207 slides with the slide groove on one side of the groove 209, thereby limiting the fixed frame 207 and preventing it from rotating. The tail end of the threaded rod 206 is connected to the top of the fixed frame 207. A roller 208 is mounted on the fixed frame 207. A drive button 205 is mounted on the head end of the threaded rod 206. By driving the threaded worm gear, the fixed frame 207 moves downward, thereby causing the roller 208 to contact the electrolytic copper foil, thereby providing a pressing effect on the electrolytic copper foil and preventing the electrolytic copper foil from loosening during transportation.

[0030] Support base 2 101 Figure 3 As shown,

[0031] Gear 105 and gear 206 are respectively provided on the side end of the support base 2 101. One side of gear 105 is connected to one end of the slitting roller 102, and one side of gear 206 is connected to one end of the conveying roller 103. Gear 105 and gear 206 are meshed, thereby indirectly causing the slitting roller 102 and the conveying roller 103 to rotate relative to each other.

[0032] A protective shell 107 is provided on the side end of the support base 2 101. The protective shell 107 is used to protect the gear 1 105 and the gear 2 106 and prevent dust from entering the gear 1 105 and the gear 2 106. The protective shell 107 is located on the outer surface of the gear 1 105 and the gear 2 106.

[0033] A motor 104 is provided on the protective shell 107. The output shaft of the motor 104 is connected to the side end of the gear 105. The motor 104 provides driving power for the gear 105.

[0034] First, the motor 104 drives the gear 105 to rotate. Since the gear 105 and the gear 2 106 are meshed, the gear 105 can drive the gear 2 106 to rotate, which indirectly drives the conveyor roller 103 and the slitting roller 102 to rotate.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
