Description

Technical Field

[0001] The invention relates to the technical field of copper foil production and processing, and in particular to an integrated foil production machine with an online annealing function. Background Art

[0002] The integrated foil production machine is a key equipment for producing electrolytic copper foil. It can realize the continuous production process of directly generating copper foil from electrolyte. It is mainly used to produce copper foil for lithium batteries, which is one of the important materials for new energy lithium batteries. With the rapid development of the new energy vehicle market, the demand for copper foil for lithium batteries is also increasing, which has promoted the rapid growth of the integrated foil production machine market.

[0003] In actual production, after the copper foil is produced, it needs to pass through the anti-oxidation tank. The anti-oxidation tank contains anti-oxidation liquid, which can form a protective film on the surface of the copper foil to prevent oxygen from contacting the surface of the copper foil, thereby improving the anti-oxidation ability of the copper foil and extending its service life. However, too much anti-oxidation liquid adheres to the surface of the copper foil and may over-react with copper, resulting in uneven discoloration on the surface of the copper foil, such as local color is too dark or too light, affecting the appearance consistency of the copper foil. Therefore, after passing through the anti-oxidation tank, the copper foil will pass through the squeeze roller group. There is a certain gap between the two rollers of the squeeze roller group, and the copper foil passes through this gap. During the passing process, the two rollers will exert a certain pressure on the copper foil to squeeze out the excess anti-oxidation liquid on the surface of the copper foil. The gap between the two squeeze rollers needs to be adjusted according to the different thicknesses of the copper foil. If the adjustment is inaccurate, it will affect the effect of removing the anti-oxidation liquid. Therefore, water-absorbing pads are usually set before and after the squeeze rollers to absorb the anti-oxidation liquid on the surface of the copper foil. However, the water-absorbing pad will become saturated after absorbing a certain amount of anti-oxidation liquid, thereby affecting the subsequent water absorption efficiency.

[0024] Combine the following Figure 1-Figure 9 The invention describes a foil production machine with online annealing function.

[0025] like Figure 1-Figure 8 As shown, in one embodiment, it includes a preparation device 1, a support plate 2, a peeling roller 3, a container tank 4, a squeezing roller group 5, an insulation box 8, a heating roller 9, a cooling roller, a finished product box, a water absorption component 6 and a water squeezing component 7.

[0026] A preparation device 1 is provided with a cathode roller, an anode plate and an anode tank; a support plate 2 is axially symmetrically arranged on both sides of the preparation device 1; a stripping roller 3 is installed on one side of the preparation device 1 and is used to separate the copper foil from the cathode roller; a container tank 4 is installed on one side of the stripping roller 3 and contains an anti-oxidation liquid inside to prevent the copper foil from oxidizing; a squeezing roller group 5 is arranged on one side of the container tank 4 to prevent excessive anti-oxidation liquid from adhering to the surface of the copper foil; an insulation box 8 is arranged on one side of the squeezing roller group 5 to insulate the copper foil; a plurality of heating rollers 9 are installed in the insulation box 8 to heat the copper foil; a cooling roller is installed on one side of the insulation box 8 to cool the copper foil; a finished product box is installed on one side of the insulation box 8 to hold the copper foil after production is completed; a water absorption component 6 is arranged between the squeezing roller group 5 and the insulation box 8 to further remove the anti-oxidation liquid on the surface of the copper foil; a water squeezing component 7 is arranged in the water absorption component 6 to squeeze out the anti-oxidation liquid absorbed in the water absorption component 6.

[0027] Specifically, in the preparation device 1, the electrolyte solution enters the electrolysis area between the anode plate and the cathode roller from the bottom of the anode tank. Through electrolysis, the cathode roller absorbs copper ions to its working surface to form copper foil. The copper foil then passes through the stripping roller 3 and separates from the cathode roller. The separated copper foil enters the container tank 4 and reacts with the anti-oxidation liquid inside to form a protective film on the surface to prevent the copper foil from undergoing oxidation reaction. The copper foil then passes through the squeezing roller group 5 to remove excess anti-oxidation liquid on the surface of the copper foil. The copper foil then enters the heat preservation box 8 and passes through multiple heating rollers 9 in sequence. In the present application, the number of heating rollers 9 is set to 3, and the surface temperature of the heating rollers 9 increases step by step. The temperature of the first heating roller 9 is the lowest, which can ensure that the surface of the copper foil is heated to approximately the same degree. In the existing production, the copper foil is usually rolled into a finished roll after production is completed and then concentratedly heated and heated. In this way, the temperatures of the inner and outer layers of the copper foil reel are different, which will also lead to differences in the quality of the inner and outer copper foils, affecting the quality of the copper foil. Passing through multiple heating rollers 9 in sequence can be very effective. In order to avoid this phenomenon, nitrogen can also be flushed into the insulation box 8, which can further prevent the oxidation of the copper foil. The heated copper foil will be cooled by the cooling roller. Appropriate heating will help certain components in the anti-oxidation liquid to better react or volatilize with the surface of the copper foil to form a more uniform and dense protective layer, thereby improving the appearance quality of the copper foil. Subsequently, cooling by the cooling roller can quickly stabilize the state of the protective layer and reduce appearance defects caused by temperature changes, such as spots and color differences. The cooled copper foil is then rolled into a finished product roll and placed. The finished product box also has an insulation function. Before the copper foil passes through the squeezing roller group 5 and does not enter the insulation box 8, the water absorption component 6 can absorb a portion of the anti-oxidation liquid on the surface of the copper foil. After the water absorption component 6 itself absorbs a certain amount of anti-oxidation liquid, it will become saturated, and the subsequent adsorption capacity of the water absorption component 6 will be reduced. At this time, the anti-oxidation liquid adsorbed in the water absorption component 6 can be removed by the water squeezing component 7, so as to ensure that the water absorption component 6 can efficiently absorb the anti-oxidation liquid.

[0028] See also Figure 3-Figure 5 As shown, in this embodiment, the water absorption component 6 is set into two groups, and the water absorption component 6 includes a fixed frame 61, a lifting plate 62 is slidably arranged on the fixed frame 61, a fixed frame 63 is fixedly arranged on the top of the lifting plate 62, a notch 64 is opened in the fixed frame 63, baffles 65 are axially symmetrically arranged on both sides of the notch 64, a groove 66 is opened in the middle of the baffle 65, a water absorption pad 67 is movably arranged in the groove 66, and the top of the water absorption pad 67 is movably abutted against the bottom of the copper foil.

[0029] Specifically, the water absorbing components 6 are set in two groups. During use, only one group of water absorbing components 6 is in contact with the surface of the copper foil. After the copper foil passes through the squeezing roller group 5, the bottom will be in contact with the top of the water absorbing pad 67. During the movement of the copper foil, the water absorbing pad 67 will absorb a part of the anti-oxidation liquid. When the water absorbing pad 67 is saturated, the lifting plate 62 moves downward along the fixing frame 61. The descent of the lifting plate 62 will drive the fixing frame 63, the baffle 65 and the water absorbing pad 67 to move downward. The length of the baffle 65 is greater than the length of the water absorbing pad 67. In order to place the absorbent pad 67 in the groove 66, another set of lifting plates 62, fixed frames 63, baffles 65 and absorbent pads 67 are moved upward until the absorbent pads 67 are in contact with the bottom of the copper foil, and then the anti-oxidation liquid adsorbed inside the absorbent pads 67 of the first set can be squeezed out, so as to ensure that the absorbent pads 67 always maintain sufficient adsorption capacity. A corresponding absorbent component 6 can also be set on the top of the copper foil. When squeezing out the anti-oxidation liquid in the absorbent pads 67, it should be noted that the anti-oxidation liquid will drip back onto the surface of the copper foil.

[0030] See also Figure 5-Figure 7 As shown, in the present embodiment, fixed rods 10 are axially symmetrically fixed on both sides of the groove 64, the bottom of the baffle 65 is movably sleeved on the outside of the fixed rod 10, a rotating plate 11 is arranged in the fixed frame 61, the rotating plate 11 is rotatably connected to the inner wall of the fixed frame 61 through a round rod 12, deflection plates 13 are movably connected at both ends of the rotating plate 11, the deflection plate 13 is rotatably connected to the end away from the rotating plate 11 with a triangular plate 14, the triangular plate 14 is rotatably connected to the inner wall of the fixed frame 61, and a movable plate 15 is movably connected between one side of the triangular plate 14 and the baffle 65.

[0031] Specifically, when the water-absorbing pad 67 is in use, the two baffles 65 are in abutment state and the slot 64 can be covered. The two water-absorbing pads 67 can absorb the anti-oxidation liquid on the surface of the copper foil passing by. When the water-absorbing pad 67 is saturated, the lifting plate 62 moves downward. During the movement, the round rod 12 is rotated clockwise. The rotation of the round rod 12 drives the rotating plate 11 to rotate, thereby driving the two deflection plates 13 to rotate and then causing the triangular plate 14 to rotate. The rotation of the triangular plate 14 will drive the movable plate 15 to rotate so that the baffles 65 on both sides rotate clockwise from a horizontal state to a vertical state, and the water-absorbing pad 67 also changes to a vertical state. This ensures that the anti-oxidation liquid in the water-absorbing pad 67 can drip down after being squeezed out and will not return to the water-absorbing pad 67. The fixed rod 10 provides support for the baffle 65. Similarly, when the baffle 65 needs to be closed, the round rod 12 can be rotated counterclockwise.

[0032] See also Figure 8 As shown, in this embodiment, the water squeezing component 7 includes a filter plate 71, which is fixedly installed in the groove 66 and fits with the water absorbent pad 67. A moving rod 72 is movably provided through the center of the filter plate 71. One end of the moving rod 72 is fixedly connected to the water absorbent pad 67. A horizontal plate 73 is movably sleeved on the outer side of the moving rod 72. The horizontal plate 73 is fixedly connected to the inner wall of the groove 66. The horizontal plate 73 and the filter plate 71 are connected by a spring 74, and the spring 74 is movably arranged on the outer side of the moving rod 72.

[0033] Specifically, when it is necessary to squeeze out the anti-oxidation liquid in the water-absorbing pad 67, the moving rod 72 is moved in the direction away from the water-absorbing pad 67. The movement of the moving rod 72 will drive the water-absorbing pad 67 to move toward the filter plate 71. The water-absorbing pad 67 itself is made of flexible material. Therefore, the water-absorbing pad 67 is deformed during the movement toward the filter plate 71 to squeeze out the liquid inside. The filter plate 71 has a plurality of filter holes on its surface, which can better allow the squeezed water in the water-absorbing pad 67 to flow out. The spring 74 will be compressed during the movement of the moving rod 72. When the water-absorbing pad 67 is needed, it is necessary to reset the water-absorbing pad 67 to its initial position and release the force applied to the moving rod 72. The cross plate 73 provides support for the spring 74.

[0034] See also Figure 8-Figure 9 As shown, in this embodiment, a circular groove 16 is opened on the baffle 65, and a limiting rod 17 is fixedly sleeved on the outer side of the fixed rod 10 located inside the circular groove 16; the end of the movable rod 72 away from the water-absorbing pad 67 is fixedly connected to the limiting plate 18, and the limiting plate 18 is movably abutted against the limiting rod 17.

[0035] Specifically, when it is necessary to squeeze water from the water absorbent pad 67, the baffle plate 65 will rotate clockwise as the lifting plate 62 moves downward. The rotation of the baffle plate 65 will drive the moving rod 72, the cross plate 73 and the limit plate 18 to rotate synchronously. The limit plate 18 will abut against the limit rod 17 during the rotation. Under the abutting force of the limit rod 17, the limit plate 18 will move in the direction away from the cross plate 73, thereby driving the moving rod 72 to pull the water absorbent pad 67 toward the filter plate 71. The water absorbent pad 67 is deformed to cause the internal liquid to flow out, thereby achieving the effect of squeezing water. The circular groove 16 provides a holding space for the limit rod 17 and the limit plate 18 to avoid the limit plate 18 and the limit rod 17 from colliding with the baffle plate 65 during the rotation process.

[0036] See also Figure 3 As shown, in the present embodiment, a positioning plate 19 is fixedly provided on one side of the lifting plate 62, a rotating frame 20 is slidably provided in the positioning plate 19, a vertical plate 21 is fixedly provided on one side of the fixed frame 61, the center of the rotating frame 20 is rotatably connected to the vertical plate 21, a fixed block 22 is fixedly provided on one end of the vertical plate 21 away from the fixed frame 61, a sliding plate 23 is slidably provided on the fixed block 22, and the top of the sliding plate 23 is slidably connected to the end of the rotating frame 20 away from the positioning plate 19.

[0037] Specifically, the reciprocating movement of the sliding plate 23 along the surface of the fixed block 22 will drive the rotating frame 20 to rotate alternately in the forward and reverse directions. The rotation of the rotating frame 20 will drive the positioning plate 19 to move reciprocatingly up and down. The up and down reciprocating movement of the positioning plate 19 will drive the lifting plate 62 to move reciprocatingly up and down, thereby realizing the up and down movement of the fixed frame 63 and the water absorbent pad 67. The vertical plate 21 provides support for the rotating frame 20.

[0038] See also Figure 3 As shown, in this embodiment, a clamping plate 24 is fixedly provided at one end of the support plate 2, a movable plate 25 is slidably provided on the clamping plate 24, a curved groove 251 is provided on the movable plate 25, and a positioning rod 26 is fixedly provided at one end of the sliding plate 23 away from the rotating frame 20, and the positioning rod 26 is slidably connected to the curved groove 251.

[0039] Specifically, when one of the positioning rods 26 is located at the height of the curved groove 251, the lifting plate 62 corresponding to the positioning rod 26 is at a high position, and the corresponding water-absorbing pad 67 is in contact with the surface of the copper foil, while the other water-absorbing pad 67 does not contact the copper foil. When the water-absorbing pad 67 needs to be replaced, the movable plate 25 is moved laterally along the clamping plate 24. The movement of the movable plate 25 will drive the curved groove 251 to move, and the curved groove 251 will move relative to the positioning rod 26, so that the two positioning rods 26 move back and forth laterally. When one of the positioning rods 26 moves from the low point to the high point of the curved groove 251, the corresponding lifting plate 62 and water-absorbing pad 67 also move upward accordingly, and the other positioning rod 26 will move from the high point to the low point of the curved groove 251, and the corresponding lifting plate 62 and water-absorbing pad 67 will move downward. The two water-absorbing pads 67 can be alternately contacted with the copper foil through the reciprocating movement of the movable plate 25, thereby avoiding the phenomenon that no water-absorbing pad 67 is in contact with the copper foil, which affects the adsorption efficiency.

[0040] See also Figure 3 As shown, in this embodiment, one end of the moving plate 25 is connected to a piston rod 27 .

[0041] Specifically, the lateral reciprocating movement of the piston rod 27 drives the lateral reciprocating movement of the moving plate 25 , which serves as a driving source.

[0042] See also Figure 4-Figure 6 As shown, in this embodiment, a gear 28 is fixedly provided at the end of the round rod 12 .

[0043] Specifically, the rotation of the gear 28 drives the round rod 12 to rotate, thereby changing the water-absorbing pad 67 between the vertical and horizontal states.

[0044] See also Figure 6 As shown, in this embodiment, a vertical slot 29 is opened in the fixing frame 63, a rack 30 is movably arranged in the vertical slot 29, the rack 30 is meshed with the gear 28 for transmission, and the end of the rack 30 away from the gear 28 is fixedly connected to the fixing frame 61.

[0045] Specifically, when it is necessary to squeeze water from the water absorbent pad 67, the downward movement of the fixed frame 63 will drive the gear 28 to move downward. During the movement, the gear 28 will mesh with the rack 30, thereby driving the gear 28 to rotate clockwise. The clockwise rotation of the gear 28 will drive the round rod 12 to rotate clockwise, so that the baffles 65 and the water absorbent pad 67 on both sides are changed from a horizontal state to a vertical state. During this process, the abutment between the limit rod 17 and the limit plate 18 will cause the moving rod 72 to move and pull the water absorbent pad 67 and the filter plate 71 to squeeze and squeeze the internal liquid. The vertical groove 29 provides a moving space for the rack 30. When the water absorbent pad 67 finishes squeezing water, the fixed frame 63 will move upward again, and the gear 28 will rotate counterclockwise to drive the baffles 65 and the water absorbent pad 67 on both sides to return to a horizontal state, so that the liquid on the surface of the copper foil can continue to be absorbed.

[0046] During implementation, the lateral reciprocating movement of the piston rod 27 will drive the lateral reciprocating movement of the moving plate 25, and the movement of the moving plate 25 will drive the curved groove 251 to move, and the curved groove 251 will move relative to the positioning rod 26, so that the two positioning rods 26 move lateral reciprocatingly. When one of the positioning rods 26 moves from the lower part to the higher part along the curved groove 251, the corresponding lifting plate 62 and the water-absorbing pad 67 will also move upward, and the other positioning rod 26 will move from the higher part to the lower part along the curved groove 251, and the corresponding lifting plate 62 and the water-absorbing pad 67 will move downward. The lateral reciprocating movement of the moving plate 25 can realize that the two water-absorbing pads 67 are alternately in contact with the copper foil, avoiding the phenomenon that there is no contact between the water-absorbing pad 67 and the copper foil, which affects the adsorption efficiency. When it is necessary to squeeze the water from the water-absorbing pad 67, the downward movement of the fixed frame 63 will drive the gear 28 to move downward. During the movement, the gear 28 will contact with the copper foil. The rack 30 is meshed to drive the gear 28 to rotate clockwise. The clockwise rotation of the gear 28 will drive the round rod 12 to rotate clockwise, so that the baffles 65 and the water absorbent pads 67 on both sides are changed from a horizontal state to a vertical state. The rotation of the baffle 65 will drive the moving rod 72, the cross plate 73 and the limit plate 18 to rotate synchronously. During the rotation of the limit plate 18, it will abut against the limit rod 17. Under the abutting force of the limit rod 17, the limit plate 18 will move in the direction away from the cross plate 73, thereby driving the moving rod 72 to pull the water absorbent pad 67 toward the filter plate 71. The water absorbent pad 67 is deformed to cause the liquid inside to flow out, thereby achieving the effect of squeezing water. When the water absorbent pad 67 finishes squeezing water, the fixed frame 63 will move upward again, and the gear 28 will rotate counterclockwise to drive the round rod 12 to rotate counterclockwise, thereby driving the baffles 65 and the water absorbent pads 67 on both sides to become horizontal again, so that the liquid on the surface of the copper foil can continue to be absorbed.
