Detailed Implementation

[0019] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Figure 1 This is a schematic diagram of the first embodiment of the waste roll processing device of this application. Figure 2 This is a front view of the first embodiment of the waste roll processing apparatus of this application; Figure 3 This is a schematic diagram of the arrangement of the guide roller group in the first embodiment of the waste roll processing device of this application; as shown Figures 1 to 3 As shown in the figure, this application discloses a waste roll processing device 100. The waste roll processing device 100 includes a support 110, a control device 120, a cutting device 130, a detection device 140, and a guiding device 150. The control device 120, the cutting device 130, the detection device 140, and the guiding device 150 are all mounted on the support 110. The guiding device 150 is used to mount and convey the copper foil roll 300. The control device 120 is connected to the guiding device 150 and is used to control the guiding device 150 to convey the copper foil roll 300 from the top of the support 110 to the bottom of the support 110. When the detection device 140 detects that the copper foil roll 300 is in a second state, the detection device 140 transmits a detection signal to the cutting device 130. The cutting device 130 cuts the copper foil roll 300 to partially break the copper foil roll 300 at the position corresponding to the cutting device 130.

[0021] This application utilizes a waste roll processing device 100 to automatically remove scrapped copper foil rolls 300. During the removal process, the copper foil roll 300 is first mounted on a guide device 150. Then, a control device 120 controls the guide device 150 to convey the copper foil on the roll 300 from the top to the bottom of a support 110. During this conveying process, a detection device 140 continuously monitors the copper foil on the roll 300. When the detection device 140 detects that the roll 300 is in a second state, it transmits a detection signal to a cutting device 130. The cutting device 130 cuts the copper foil at the corresponding position on the roll 300, causing the roll 300 to partially break at the position corresponding to the cutting device 130, thus achieving automatic removal of the scrapped copper foil. This eliminates the need for manual removal and allows for timely removal of scrapped rolls, improving the efficiency of scrapped copper foil removal.

[0022] It should be noted that the copper foil roll 300 in this application includes scrap rolls with abnormalities during the production process and experimental rolls during the experimental production process. The second state of the copper foil roll referred to in the embodiments of this application can be understood as the state in which foreign objects are present on the surface of the copper foil of the copper foil roll 300 or the state in which the copper foil is conveyed to a preset number of meters. The preset number of meters of copper foil conveying can be set by the user according to actual production needs.

[0023] Specifically, the control device 120 includes a motor 121, and the guide device 150 includes a main guide roller 151. The main guide roller 151 is mounted on the top of the bracket 110 and connected to the motor 121. The copper foil roll 300 is mounted on the main guide roller 151. When the detection device 140 detects that the copper foil roll 300 is in the first state, the motor 121 controls the main guide roller 151 to rotate, and the main guide roller 151 drives the copper foil on the copper foil roll 300 to be conveyed from the top of the bracket 110 to the bottom of the bracket 110. When the detection device 140 detects that the copper foil roll 300 is in the second state, the motor 121 controls the main guide roller 151 to stop rotating.

[0024] Before removing the scrapped copper foil roll 300, the scrapped copper foil roll 300 is first installed on the main guide roller 151 at the top of the bracket 110. Then, the motor 121 is started, and the main guide roller 151 is rotated by the motor 121, thereby rotating the copper foil roll 300 and providing traction force for the copper foil roll 300. Since the copper foil roll 300 is installed at the top of the bracket 110, under the combined action of the weight of the copper foil on the copper foil roll 300 and the traction force provided by the motor 121, the copper foil on the copper foil roll 300 will be conveyed from the top of the bracket 110 to the bottom of the bracket 110.

[0025] When the copper foil on the copper foil roll 300 is conveyed downward to the position of the detection device 140, the detection device 140 performs real-time detection on the copper foil on the copper foil roll 300 and determines whether the copper foil on the copper foil roll 300 is in the first state or the second state, thereby controlling the main guide roller 151 through the motor 121 to drive the copper foil on the copper foil roll 300 to be conveyed or stopped.

[0026] When the detection device 140 detects that the copper foil on the copper foil roll 300 is in the first state, the detection device 140 transmits a detection signal to the motor 121. The motor 121 controls the main guide roller 151 to rotate according to the acquired detection signal to transport the copper foil, thereby improving the efficiency of sorting and collecting the copper foil. Here, the copper foil on the copper foil roll 300 being in the first state can be understood as the copper foil surface being free of foreign objects, or the copper foil not yet reaching the preset length.

[0027] When the detection device 140 detects that the copper foil on the copper foil roll 300 is in the second state, it indicates that there are foreign objects on the surface of the copper foil, or that the copper foil being transported has reached the preset length. At this time, the detection device 140 transmits the detection signal to the motor 121, and the motor 121 controls the main guide roller 151 to stop rotating, so that the copper foil on the copper foil roll 300 is suspended on the support 110. This is beneficial for the operator to observe the surface condition of the copper foil, and facilitates stable cutting of the copper foil for rejection. This effectively prevents foreign objects on the surface of the waste foil from entering the copper melting tank with the waste foil, causing abnormalities in the physical properties or appearance of the copper foil.

[0028] Furthermore, the guiding device 150 also includes a flattening roller group 152 and a guide roller group 160, which are sequentially arranged below the main guiding roller 151 and connected to the support 110; the copper foil self-guided roller 151 on the copper foil roll 300 passes through the flattening roller group 152 and the guide roller group 160 in sequence; the flattening roller group 152 is used to flatten the surface of the copper foil on the copper foil roll 300, and the guide roller group 160 is used to guide the copper foil on the copper foil roll 300 to the waste foil channel 170 at the bottom of the support 110.

[0029] When the copper foil passes through the flattening roller group 152, the flattening roller group 152 applies a certain pressure to the surface of the copper foil. By rolling, the wrinkles and unevenness on the surface of the copper foil are gradually eliminated, making the surface of the copper foil smoother and flatter. This ensures that the copper foil falls flat to the guide roller group 160, so that the guide roller group 160 can guide the copper foil on the copper foil roll 300 to the waste foil channel 170 at the bottom of the support 110 for recycling, providing a good foundation for subsequent processing.

[0030] When the copper foil falls from the flattening roller group 152 to the guide roller group 160, the guide roller group 160 can guide the copper foil toward the waste foil channel 170 at the bottom of the support 110, and ensure that the copper foil will not deviate or entangle during the conveying process, thus ensuring the stability and smoothness of the copper foil conveying.

[0031] Specifically, the support 110 includes a first support arm 111 and a second support arm 112, which are arranged opposite to each other; the flattening roller group 152 includes a first flattening roller 153 and a second flattening roller 154, which are respectively connected between the first support arm 111 and the second support arm 112; and the first flattening roller 153 and the second flattening roller 154 are arranged at intervals in the horizontal direction, and the copper foil portion of the copper foil roll 300 is located in the gap between the first flattening roller 153 and the second flattening roller 154, and the first flattening roller 153 and the second flattening roller 154 clamp the copper foil surface of the copper foil roll 300 from both sides of the copper foil.

[0032] When the copper foil on the copper foil roll 300 passes through the gap between the first flattening roller 153 and the second flattening roller 154, the first flattening roller 153 and the second flattening roller 154 roll and clamp the surface of the copper foil from both sides, and apply pressure to the surface of the copper foil on both sides at the same time. In this way, the surface of the copper foil is flattened by the rolling cooperation of the first flattening roller 153 and the second flattening roller 154, so that the copper foil can fall flat onto the guide roller group 160. This provides a guarantee that the guide roller group 160 can smoothly and stably guide the copper foil.

[0033] Furthermore, the guide roller assembly 160 includes a first guide roller 161, a second guide roller 162, and a third guide roller 164. The first guide roller 161, the second guide roller 162, and the third guide roller 164 are spaced apart from the top to the bottom of the bracket 110 and are respectively connected between the first support arm 111 and the second support arm 112. The first guide roller 161, the second guide roller 162, and the third guide roller 164 are staggered in the vertical direction. The copper foil on the copper foil roll 300 passes through different sides of the first guide roller 161, the second guide roller 162, and the third guide roller 164 in sequence.

[0034] In this embodiment, the first guide roller 161, the second guide roller 162, and the third guide roller 164 are arranged in a staggered manner, so that when the copper foil passes through the guide roller group 160, the first guide roller 161, the second guide roller 162, and the third guide roller 164 can change its traveling direction and tension distribution.

[0035] As the copper foil passes around one side of the first guide roller 161 and then passes different sides of the second guide roller 162 and the third guide roller 164, the copper foil will bend and stretch to varying degrees on the surface of each guide roller. Through the guiding action of the first guide roller 161, the copper foil can initially adjust its direction of travel, making it move more accurately toward the second guide roller 162. The second guide roller 162 further changes the direction of the copper foil, and at the same time cooperates with the first guide roller 161 to apply a certain tension to the copper foil, ensuring that the copper foil remains taut during the transmission process and avoiding slack or wrinkles.

[0036] The third guide roller 164 serves to guide and stabilize the copper foil, allowing it to continue to be transported downwards in a stable manner until it falls into the waste foil channel 170 at the bottom of the support 110, facilitating copper foil recycling and preparing it for subsequent processing steps.

[0037] Meanwhile, with the cooperation of the first guide roller 161, the second guide roller 162 and the third guide roller 164, the waste foil can be prevented from shifting significantly during the cutting process, and it also acts as a buffer when the waste foil falls after being cut.

[0038] Furthermore, the detection device 140 is located between the flattening roller group 152 and the guide roller group 160; the detection device 140 includes a first detection device 141 and a second detection device 142, the first detection device 141 and the second detection device 142 are respectively connected between the first support arm 111 and the second support arm 112, and the first detection device 141 and the second detection device 142 are spaced apart in the horizontal direction; the copper foil portion on the copper foil roll 300 is located in the gap between the first detection device 141 and the second detection device 142, and the first detection device 141 and the second detection device 142 are used to detect whether the copper foil on the copper foil roll 300 is in a first state or a second state.

[0039] When the copper foil is conveyed to the gap between the first detection device 141 and the second detection device 142, the first detection device 141 and the second detection device 142 respectively detect the surface of the copper foil from both sides in the horizontal direction, thereby improving the accuracy of the detection.

[0040] In this embodiment, the cutting device 130 is located between the first guide roller 161 and the second guide roller 162. The cutting device 130 includes a telescopic device 131 and a cutter 132. One end of the telescopic device 131 is connected to the first support arm 111, and the other end is connected to the cutter 132. The telescopic device 131 can extend and retract along the extension direction of the second guide roller 162 to drive the cutter 132 to cut along the width direction of the copper foil in the copper foil roll 300. The telescopic device 131 can be a hydraulic rod, which drives the cutter 132 to cut along the width direction of the copper foil in the copper foil roll 300, causing the copper foil to break at the cut position, thereby removing the copper foil. This eliminates the need for manual cutting, avoids direct contact between the operator and the copper foil, reduces errors caused by manual cutting, and improves cutting efficiency.

[0041] Specifically, the motor 121 and the telescopic device 131 are respectively connected to the first detection device 141 and the second detection device 142. When the first detection device 141 and the second detection device 142 detect that the copper foil roll 300 is in the first state, the motor 121 starts to work, and the telescopic device 131 controls the cutter 132 to return to the initial position. When the first detection device 141 and / or the second detection device 142 detect that the copper foil on the copper foil roll 300 is in the second state, the motor 121 stops working, and the telescopic device 131 controls the cutter 132 to cut the copper foil at the corresponding position on the copper foil roll 300, so as to break the copper foil of the copper foil roll 300 at the position of the corresponding cutting device 130.

[0042] When the first detection device 141 and the second detection device 142 detect the copper foil from both sides respectively and determine that both sides of the copper foil are in the first state, the motor 121 drives the main guide roller 151 to rotate, thereby causing the copper foil roll 300 on the main guide roller 151 to rotate, so that the copper foil on the copper foil roll 300 is conveyed. At this time, the telescopic device 131 controls the cutter 132 to remain in the initial position and does not cut the copper foil, thereby ensuring the normal conveying of the copper foil.

[0043] When either the first detection device 141 or the second detection device 142 detects a foreign object or reaches a preset length on one of the surfaces of the copper foil, the copper foil is determined to be in the second state. At this time, the motor 121 stops controlling the main guide roller 151, thereby stopping its rotation and keeping the copper foil roll 300 on the main guide roller 151 stationary. The copper foil on the roll 300 is then suspended on the support 110. At this time, the telescopic device 131 controls the cutter 132 to cut the copper foil roll 300, thus removing the copper foil. The copper foil removed by the cutter 132 will automatically fall into the waste foil packaging area through the waste foil channel 170 at the bottom of the support 110. After processing, it can be put into the copper melting tank for recycling.

[0044] In this embodiment of the application, the waste roll processing device 100 automatically rejects copper foil rolls to facilitate the collection of waste foil, reduce the consumption of manpower and material resources and the direct contact between waste foil and personnel, ensure that the subsequent production progress is not affected, protect personnel safety, and effectively prevent foreign objects from being trapped in the waste foil, which would affect the physical properties of the copper foil during recycling.

[0045] Figure 4 This is a schematic diagram of a second embodiment of the waste roll processing device of this application, as shown below. Figure 4 As shown, a cutting groove 163 is provided on the side of the second guide roller 162 near the cutter 132. The cutting groove 163 corresponds to the position of the cutter 132 and extends along the length direction of the second guide roller 162. When the copper foil on the copper foil roll 300 is in the second state, the cutter 132 is partially embedded in the cutting groove 163 to cut the copper foil on the copper foil roll 300.

[0046] The difference between this embodiment and the previous embodiment is that, in this embodiment, a cutting groove 163 is provided on the second guide tube located below the cutter 132, corresponding to the position of the cutter 132. When the cutter 132 starts working, it can cut the copper foil on the copper foil roll 300 along the extension direction of the cutting groove 163. Furthermore, since the cutter 132 is partially embedded in the cutting groove 163 during cutting, the cutting groove 163 limits the movement of the cutter 132, ensuring that the cutter 132 can only move along the extension direction of the cutting groove 163. This prevents the cutter 132 from deviating from the cutting track and improves the stability of the cutting device 130. At the same time, the cutting groove 163 extends along the length direction of the second guide roller 162, ensuring that the cutter 132 can cut stably throughout the width of the copper foil, resulting in a more uniform cutting effect.

[0047] Furthermore, the design of the cutting groove 163 can also prevent the cutter 132 from directly contacting the second guide roller 162 during the cutting process, thus avoiding excessive damage to the second guide roller 162. This is because the cutting groove 163 provides cutting space for the cutter 132. When the cutter 132 cuts the copper foil, most of the force is applied to the copper foil, reducing the direct contact and friction between the cutter 132 and the surface of the second guide roller 162, thereby extending the service life of the second guide roller 162.

[0048] Figure 5 This is a schematic diagram of an embodiment of the copper foil system of this application, as shown below. Figure 5As shown in the illustration, this application also discloses a copper foil system 10, including a recycling device 200. The copper foil system 10 further includes the aforementioned waste roll processing device 100, which is connected to the recycling device 200. Copper foil rolls 300 cut by the waste roll processing device 100 fall into the recycling device 200 for recycling, thus avoiding messy stacking of copper foil and facilitating efficient recycling.

[0049] In the traditional process of removing scrap copper foil, workshop employees usually manually remove the foil and then collect and sort it, which is inefficient.

[0050] Based on the above problems, this application uses a waste roll processing device 100 to automatically remove scrapped copper foil rolls 300. During the removal process, the copper foil rolls 300 are first mounted on a guide device 150. Then, a control device 120 controls the guide device 150 to convey the copper foil on the rolls 300 from the top to the bottom of the support 110. During this conveying process, a detection device 140 continuously monitors the copper foil on the rolls 300. When the detection device 140 detects that the rolls 300 are in a second state, it transmits a detection signal to a cutting device 130. The cutting device 130 cuts the copper foil at the corresponding position on the rolls 300, causing the rolls 300 to partially break at the position corresponding to the cutting device 130, thus achieving automatic removal of scrapped copper foil. This eliminates the need for manual removal, allows for timely removal of scrapped rolls, improves the removal efficiency of scrapped copper foil, and ultimately enhances the overall operating efficiency of the copper foil system 10.
