Description

Technical Field

[0001] This utility model relates to the field of copper foil production technology, specifically to a lithium battery copper foil edge cutting early warning and protection device. Background Technology

[0002] In the production process of copper foil for lithium batteries, the edges of the copper foil need to be trimmed using a cutting roller. The resulting strips of copper foil scrap, known as bait, need to be recycled using a winding roller. Because the bait is formed only by cutting the edges of the copper foil, it is narrow and has cutting stress at the edges. This edge effect makes the bait structure fragile and prone to breakage during transport.

[0003] When the bait breaks, the fragments fall directly into the electrolytic tank below. This tank contains electrolyte and is energized. The copper foil bait, upon falling into the electrolyte, triggers a chemical reaction, causing electrical damage to the expensive titanium rollers. As a core component in copper foil production, repairing these titanium rollers requires not only high labor costs but also significant downtime, severely impacting production efficiency and causing substantial economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery copper foil edge-cutting early warning and protection device. By installing protective components, guiding components, and baffles, it can efficiently intercept broken bait, preventing it from falling into the electrolytic cell and avoiding the high equipment repair costs and long-term downtime losses caused by electric shock damage to the titanium roller. Simultaneously, in conjunction with the first and second sensors, it can monitor the bait transmission status in real time around the clock. Once bait breakage is detected, an audible and visual alarm will be triggered instantly, providing immediate early warning of the fault and offering operators a rapid response window. This solves the technical problem of untimely response from on-site personnel after bait breakage, minimizing production losses.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-3A lithium battery copper foil edge-cutting early warning and protection device includes a fixed base 1, an electrolytic cell 2, a conductive roller 3, a bait winding roller 4, at least one bait transition roller 5, two protective structures 6, and an early warning structure 7. The fixed base 1 serves as the supporting foundation for the entire device and can be made of high-strength metal material. It has anti-slip and shock-absorbing pads at the bottom to ensure stability during copper foil production and prevent bait transport deviation due to equipment vibration. The fixed base 1 is fixed with the electrolytic cell 2, conductive roller 3, bait winding roller 4, and at least one bait transition roller 5. The electrolytic cell 2 is located in the middle of the fixed base 1. The cell body can be made of corrosion-resistant material and contains electrolyte, providing a reaction space for copper foil electrolytic forming. The conductive roller 3 is rotatably mounted on the top of the fixed base 1 via bearings. The roller surface is polished and used to support the copper foil body to be cut. The height and horizontal position of the conductive roller 3 can be finely adjusted to ensure the copper foil body remains flat during transport, providing a stable foundation for subsequent edge-cutting processes and bait transport. A cutter (not shown in the figure) is provided at the position of the fixed base 1 corresponding to the conductive roller 3. This is existing technology and will not be described in detail here. The bait winding roller 4 is rotatably mounted on both sides of the fixed base 1 via a drive motor and bearings, and can wind up the bait formed by the cut edges. The rotation speed of the bait winding roller 4 can be adjusted synchronously with the copper foil transmission speed to avoid the bait from stretching and breaking due to excessively fast or slow winding speed. The bait transition roller 5 is rotatably mounted on the fixed base 1 via bearings. The diameter of the bait transition roller 5 is adapted to the width of the bait, and it forms a transmission path with the conductive roller 3 and the bait winding roller 4, which can guide the transmission direction of the bait. The number of bait transition rollers 5 can be adjusted according to the overall length of the device to ensure that the bait is always kept taut during transmission and to reduce the risk of breakage due to slack. The protective structure 6 is symmetrically arranged on the fixed base 1, located below both sides of the conductive roller 3, corresponding to the easily broken area of ​​the bait transmission. It can prevent broken bait from falling into the electrolysis tank 2. The early warning structure 7 is arranged on the fixed base 1, corresponding to the bait transmission area of ​​the bait transition roller 5. This area is a critical node for bait transmission. Breakage failure is likely to occur here and can be detected quickly. It can sense the bait transmission status in real time and issue an early warning signal in time when the bait breaks.

[0019] Preferably, the protective structure 6 includes a protective component 61, a guiding component 62, and a baffle 63. The protective component 61 is located below one side of the conductive roller 3, corresponding to the initial transmission section where the bait is discharged from the conductive roller 3, and can immediately catch any broken bait. The guiding component 62 is located on the fixed base 1, with its top positioned below the protective component 61, and can guide the broken bait caught by the protective component 61 to a designated collection area, preventing the bait from falling off again during transmission. The baffle 63 can be made of transparent acrylic sheet. The baffle 63 is obliquely mounted on the fixed base 1 at an angle of 45°-60°. A corresponding positioning groove can be provided on the fixed base 1 and fixed with bolts. The baffle 63 is located between the bottom of the electrolytic cell 2 and the bottom of the guide component 62. The height of the baffle 63 is higher than the bottom outlet end of the guide component 62, and the width can cover the electrolytic cell 2. It can block the bait that falls due to the transmission deviation of the guide component 62, forming a second layer of protection and completely preventing the bait from falling into the electrolytic cell 2. The baffle 63 can be made of transparent acrylic sheet. The transparent material makes it easy for staff to observe the bait transmission status.

[0020] Preferably, the protective component 61 includes a protective box 611 with a top opening and a guide groove 612. The protective box 611 is inclined and positioned below one side of the conductive roller 3. The protective box 611 can be formed by bending a metal sheet. The width of the top opening is greater than the width of the bait, and the inclination angle is set to 15°-30°. The inclined design allows the received broken bait to automatically slide to one end using gravity, avoiding accumulation inside the box. The inner wall of the protective box 611 can be provided with a smooth coating to reduce frictional damage when the bait slides. The guide groove 612 is located at the end of the protective box 611 away from the conductive roller 3. The width of the groove opening is the same as the width of the outlet end of the protective box 611, and the guide groove 612 is directly opposite the guide component 62. This ensures that the bait in the protective box 611 can fall accurately and smoothly into the guide component 62, avoiding the risk of falling due to bait deviation.

[0021] Preferably, the guiding component 62 includes a guiding trough plate 621 and a vertical trough plate 622. The guiding trough plate 621 is inclinedly disposed on the fixed base 1. The guiding trough plate 621 can be made of metal, with a U-shaped cross-section and an inclination angle of 20°-40°. The top of the guiding trough plate 621 is aligned with the bottom of the guiding trough 612, and the trough width can cover the guiding trough 612. It can receive the bait falling from the guiding trough 612 and transmit the bait downward along a fixed path through the inclined structure. The vertical trough plate 622 is disposed at the bottom of the guiding trough plate 621 and can be integrally formed with the guiding trough plate 621. It can be fixed to the corresponding position on the fixed base 1 by means of a U-shaped plate and bolts. This can ensure that after the bait is transmitted from the guiding trough plate 621 to the vertical trough plate 622, it can fall vertically onto the fixed base 1, avoiding horizontal deviation and proximity to the electrolysis cell 2 during the transmission process.

[0022] Preferably, the early warning structure 7 includes a mounting assembly, a first sensor 71, and an alarm 72. The mounting assembly is mounted on the fixed base 1 and can fix and adjust the installation position of the first sensor 71 to ensure that the first sensor 71 can accurately sense the bait status. The first sensor 71 is connected to the mounting assembly and can be a photoelectric sensor with its probe facing the bait on the bait transition roller 5. The first sensor 71 can detect whether there is bait on the bait transition roller 5 in real time. When the bait breaks, the first sensor 71 can instantly detect the signal change and transmit the signal to the alarm 72. The alarm 72 is located on the top of the fixed base 1 and has a built-in red light and buzzer. It can be electrically connected to the first sensor 71 through a wire. When the first sensor 71 detects that the bait has broken, the alarm 72 will simultaneously trigger the flashing red light and the buzzer to sound an alarm, reminding the staff to stop the machine in time to avoid the fault from escalating.

[0023] Preferably, the mounting assembly includes a mounting roller 73 and an L-shaped mounting plate 74. The mounting roller 73 can be a metal rod, with one end fixedly connected to the fixed base 1 and the other end rotatably mounted with a bait transition roller 5 via a bearing. The mounting plate 74 can be made of metal sheet bent into an L-shape, with one end of the mounting plate 74 sleeved on the mounting roller 73 and the other end provided with a first sensor 71. The probe of the first sensor 71 faces the bait on the bait transition roller 5 to ensure that the probe can accurately monitor the state of the bait.

[0024] Preferably, to adapt to the monitoring needs of different sized baits, the mounting assembly further includes a mounting sleeve 75, a connecting plate 76, and an adjusting screw 77; the mounting sleeve 75 can be made of a metal sleeve, fitted onto the mounting roller 73 and slidable along the axial direction of the mounting roller 73; the mounting sleeve 75 is welded and fixed to one end of the mounting plate 74; by sliding the mounting sleeve 75, the mounting plate 74 can be moved synchronously to adjust the horizontal position of the first sensor 71, adapting to the sensing needs of baits of different widths; the connecting plate 76 is located at the end of the mounting plate 74 away from the first sensor 71. It can be made of metal sheet, and a nut with a threaded hole can be embedded in the middle of the plate for welding and fixing. The adjusting screw 77 can be a metal screw with external threads on its surface, passing through the threaded hole of the connecting plate 76 and extending into the mounting sleeve 75, with its end pressed against the surface of the mounting roller 73. The adjusting screw 77 is screwed into the connecting plate 76. By tightening the adjusting screw 77, the end of the screw can be pressed tightly against the mounting roller 73 to fix the position of the mounting sleeve 75. Loosening the adjusting screw 77 allows the mounting sleeve 75 to slide, adjusting the horizontal position of the first sensor 71.

[0025] Preferably, the mounting assembly further includes an oblong hole 78, which is disposed on the mounting plate 74, and a first sensor 71 is disposed in the oblong hole 78. By adjusting the mounting position of the first sensor 71 in the oblong hole 78, the first sensor 71 can be adjusted to ensure that the probe is aligned with the bait, thereby reducing false alarms caused by the bait shifting during movement.

[0026] Preferably, the warning structure 7 further includes a second sensor 79. The second sensor 79 can be the same photoelectric sensor as the first sensor 71, located below the conductive roller 3 on the side away from the first sensor 71. It can be fixed to the mounting base 1 by an independent mounting bracket, with the probe angled upwards facing the bait surface between the conductive roller 3 and the cutter. The second sensor 79 and the alarm 72 can be electrically connected by a wire, and can sense the transmission status of the bait on the conductive roller 3 in real time. When the bait breaks near the root of the conductive roller 3, the second sensor 79 can first capture the signal of the bait disappearing and immediately transmit the breakage signal to the alarm 72, triggering the alarm 72 to simultaneously flash a red light and sound a buzzer. This forms a dual monitoring mechanism with the first sensor 71, covering the initial and transitional segments of bait transmission. This avoids the delayed detection of the first sensor 71 after the bait breaks at this point, further improving the timeliness and accuracy of the warning.

[0027] The specific working principle is as follows: In use, the copper foil body to be cut is supported on the conductive roller 3. After being cut by the cutting roller, the bait formed passes through the bait transition roller 5 in sequence and is finally wound up and recycled by the bait winding roller 4.

[0028] Because the edges of the bait are fragile and easily broken, when the bait breaks between the conductive roller 3 and the bait transition roller 5, or between the bait transition roller 5 and the bait take-up roller 4, the broken bait fragments will fall downwards under the influence of gravity. At this time, the protective box 611 below the conductive roller 3 will first catch the falling bait. The inclined protective box 611 causes the bait to slide along the box to the guide groove 612, and then fall into the guide trough plate 621 below through the guide trough 612. The guide trough plate 621 continues to guide the bait to the vertical trough plate 622 through the inclined structure, and finally guides it into the designated collection device through the vertical trough plate 622. At the same time, the inclined baffle 63 located between the electrolytic cell 2 and the guide trough plate 621 forms a second layer of protection. Even if a small amount of bait deviates from the guide trough plate 621 and falls, it will be blocked by the baffle 63 to prevent it from falling into the electrolytic cell 2 and causing chemical reaction and damage to the titanium roller by electric shock.

[0029] The first sensor 71 of the early warning structure 7 is fixed to the side of the bait transfer roller 5 by a mounting assembly, with its probe facing downwards towards the bait on the transfer roller, sensing the presence of bait in real time. During normal bait transfer, the first sensor 71 continuously detects the bait signal, and the alarm 72 is in standby mode. When the bait breaks, the bait on the bait transfer roller 5 disappears, and the first sensor 71 instantly loses the bait sensing signal. It immediately transmits the signal to the terminal control system, which triggers the alarm 72. The alarm 72 simultaneously illuminates a red light and emits a sharp alarm sound, reminding staff to stop the machine in time to avoid equipment damage and the escalation of production accidents caused by prolonged transfer of broken bait.
