Description

Technical Field

[0001] This application belongs to the field of coating technology, and in particular relates to a cutting device and coating equipment. Background Technology

[0002] In the current dry coating process, the electrode film needs to undergo multiple cutting processes before it can be laminated with the foil.

[0003] The current dry coating method mainly uses a multi-roller parallel arrangement. The electrode film is attached to the roller surface before being laminated with the foil. The cutter must not damage the roller surface while cutting the film, otherwise scratches will form on the roller surface, which will easily lead to the generation of dust residue and affect the performance of the battery cell; it will also affect the life of the cutter and the roller.

[0004] In the prior art, the cutter and the distance sensor are usually mounted on the same mounting base. Therefore, the distance between the cutter and the roller surface can be calculated by measuring the distance from the roller surface using the distance sensor. However, the measurement position of the distance sensor on the roller is not the position where the cutter contacts the roller surface. The cylindricity of the roller must be considered when calculating the distance between the cutter and the roller surface, which will introduce deviation and thus affect the measurement accuracy.

Detailed Implementation

[0037] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0038] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0042] First, it should be noted that the Z-direction mentioned in the embodiments of this application refers to the appendix. Figures 1-6 The marked direction.

[0043] like Figures 1-6 As shown, according to a first aspect of the embodiments of this application, a cutting device is provided, including a cutting mechanism 1. The cutting mechanism 1 includes a cutting assembly 11, a mounting plate 12, and a detection assembly 13. The cutting assembly 11 is capable of cutting material located on a roller surface 3. The cutting assembly 11 is disposed on the mounting plate 12 via an elastic member 14. The detection assembly 13 is disposed on the mounting plate 12 and is capable of detecting the position of the cutting assembly 11.

[0044] like Figures 1-5As shown, the cutting device includes a cutting mechanism 1, which includes a cutting assembly 11, a mounting plate 12, and a detection assembly 13. The cutting assembly 11 is used to cut the film located on the roller surface 3.

[0045] To further explain, the cutter assembly 11 is mounted on the mounting plate 12 via an elastic element 14. That is, one end of the elastic element 14 is connected to the cutter assembly 11, and the other end is connected to the mounting plate 12. When the cutter assembly 11 contacts the roller surface 3, the cutter assembly 11 compresses the elastic element 14, and the cutter assembly 11 also changes position relative to the mounting plate 12. The detection component 13 is mounted on the mounting plate 12. When the position of the cutter assembly 11 relative to the mounting plate 12 changes, the detection component 13 can detect the position change of the cutter assembly 11. Therefore, it can be determined that the cutter assembly 11 has touched the roller surface 3, and thus the movement of the cutter mechanism 1 can be stopped to avoid the cutter assembly 11 scratching the roller surface 3. By detecting whether the cutter assembly 1 has changed position to determine whether the cutter assembly 1 has touched the roller surface 3, the detection deviation caused by the cylindricity of the roller can be avoided, thereby improving the detection accuracy.

[0046] To further explain, one end of the elastic element 14 is connected to the cutter assembly 11, and the other end of the elastic element 14 is connected to the side of the mounting base 112 near the mounting plate 12. When the cutter assembly 11 disengages from the roller surface 3, the elastic element 14 can reset the cutter assembly 11.

[0047] Preferably, the elastic element 14 can be a spring.

[0048] In one optional embodiment, the detection component 13 includes a distance sensor 131 disposed on the mounting plate 12; when the cutter assembly 11 contacts the roller surface 3, the cutter assembly 11 moves away from the roller surface 3 and compresses the elastic member 14, and the distance sensor 131 can detect the distance between the cutter assembly 11 and the distance sensor 131.

[0049] like Figure 2 and Figure 6As shown, the distance sensor 131 is disposed on the side of the mounting plate 12 facing the cutter assembly 11. The distance sensor 131 can detect the positional change between the cutter assembly 11 and the distance sensor 131. When the cutter assembly 11 contacts the roller surface 3, the roller surface 3 will generate a reaction force on the cutter assembly 11. The cutter assembly 11, under the reaction force, will compress the elastic element 14, so the cutter assembly 11 will change position relative to the distance sensor 131. The distance sensor 131 detects the movement of the cutter assembly 11, and thus can stop the movement of the cutter mechanism 1 to avoid the cutter assembly 11 scratching the roller surface 3. In this embodiment, its detection accuracy is high, thereby preventing the cutter assembly 11 from scratching the roller surface 3.

[0050] In one alternative embodiment, the detection component 13 includes a pressure sensor 132 disposed between the elastic member 14 and the mounting plate 12; when the cutter assembly 11 contacts the roller surface 3, the cutter assembly 11 moves away from the roller surface 3 and compresses the elastic member 14, and the pressure sensor 132 can detect the pressure change of the elastic member 14.

[0051] like Figure 3 and Figure 5 As shown, the pressure sensor 132 is disposed on the side of the mounting plate 12 facing the cutter assembly 11. One end of the elastic element 14 is connected to the cutter assembly 11, and the other end of the elastic element 14 is connected to the pressure sensor 132. The pressure sensor 132 can monitor the pressure change of the elastic element 14. When the cutter assembly 11 contacts the roller surface 3, the roller surface 3 will generate a reaction force on the cutter assembly 11. The cutter assembly 11, under the reaction force, will compress the elastic element 14. The pressure sensor 132 will monitor the pressure change of the elastic element 14, thereby stopping the movement of the cutter mechanism 1 to avoid the cutter assembly 11 scratching the roller surface 3. In this embodiment, its detection accuracy is high, thus preventing the cutter assembly 11 from scratching the roller surface 3.

[0052] In one optional embodiment, the detection component 13 includes a conductive rod 134 and a power supply component 133. The conductive rod 134 is disposed on the mounting plate 12. One end of the power supply component 133 is connected to the conductive rod 134, and the other end of the power supply component 133 is connected to the cutter assembly 11. When the cutter assembly 11 contacts the roller surface 3, the cutter assembly 11 contacts the conductive rod 134, and the conductive rod 134, the cutter assembly 11, and the power supply component 133 form a circuit. Alternatively, when the cutter assembly 11 contacts the roller surface 3, the cutter assembly 11 separates from the conductive rod 134, and the circuit formed by the conductive rod 134, the cutter assembly 11, and the power supply component 133 is broken.

[0053] like Figure 1 and Figure 4As shown, the detection component 13 includes a conductive rod 134 and a power supply component 133; wherein, the conductive rod 134 is disposed on the mounting plate 12, one end of the power supply component 133 is connected to the conductive rod 134, and the other end is connected to the cutter assembly 11.

[0054] In one specific embodiment, when the cutter assembly 11 is not in contact with the roller surface 3, the cutter assembly 11 abuts against the conductive rod 134, so the cutter assembly 11, the conductive rod 134, and the power supply component 133 form a circuit; when the cutter assembly 11 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter assembly 11, which can separate the cutter assembly 11 from the conductive rod 134, so the circuit formed by the cutter assembly 11, the conductive rod 134, and the power supply component 133 will be broken. That is to say, when the circuit formed by the cutter assembly 11, the conductive rod 134, and the power supply component 133 is broken, the cutter assembly 11 has already touched the roller surface 3, so the movement of the cutter mechanism 1 can be stopped to avoid the cutter assembly 11 scratching the roller surface 3.

[0055] In another specific embodiment, when the cutter assembly 11 is not in contact with the roller surface 3, the cutter assembly 11 and the conductive rod 134 are in a separated state. When the cutter assembly 11 comes into contact with the roller surface 3, the roller surface 3 exerts a force on the cutter assembly 11, which enables the cutter assembly 11 to come into contact with the conductive rod 134. Therefore, the cutter assembly 11, the conductive rod 134 and the power supply component 133 will form a circuit. That is to say, the cutter assembly 11 has already touched the roller surface 3, so the movement of the cutter mechanism 1 can be stopped to avoid the cutter assembly 11 scratching the roller surface 3.

[0056] In one optional embodiment, the cutter assembly 11 includes a cutter 111 and a mounting base 112. The mounting base 112 includes a first end 1121 and a second end 1122. The cutter 111 is disposed at the first end 1121 and located on the side of the mounting base 112 away from the mounting plate 12. One end of the elastic member 14 is connected to the end of the first end 1121 near the mounting plate 12. The cutter mechanism 1 further includes a mounting bracket 16. One end of the elastic member 14 is connected to the mounting plate 12, and the other end of the elastic member 14 is connected to the side of the mounting base 112 near the mounting plate 12. One end of the mounting bracket 16 is connected to the mounting plate 12, and the other end of the mounting bracket 16 is rotatably connected to the mounting base 112 and located between the first end 1121 and the second end 1122. When the cutter 111 contacts the roller surface 3, the mounting base 112 can rotate relative to the mounting bracket 16.

[0057] like Figures 1-3As shown, the cutter assembly 11 includes a cutter 111 and a mounting base 112; the cutter 111 is used to cut the film on the roller surface 3, and the mounting base 112 provides a mounting position for the cutter 111; wherein, the mounting base 112 includes a first end 1121 and a second end 1122, the first end 1121 and the second end 1122 are located at both ends of the mounting base 112, the cutter 111 is disposed at the first end 1121 of the mounting base 112, and the cutter 111 is located on the side of the mounting base 112 away from the mounting plate 12, and the roller is located on the side of the mounting base 112 away from the mounting plate 12, so the cutter 111 and the roller can be arranged adjacent to each other so that the cutter 111 can cut the film on the roller.

[0058] The cutting mechanism 1 also includes a mounting bracket 16; one end of the mounting bracket 16 is fixedly connected to the mounting plate 12, and the other end of the mounting bracket 16 is rotatably connected to the mounting base 112. The mounting bracket 16 is located between the first end 1121 and the second end 1122. Since the cutter 111 is located at the first end 1121, when the cutter 111 contacts the roller surface 3, the roller surface 3 will exert a force on the cutter 111. Under the action of this force, the mounting base 112 will rotate relative to the mounting bracket 16. Therefore, the first end 1121 will move downward in the Z direction, and the second end 1122 will move upward in the Z direction.

[0059] like Figure 2 As shown, in the embodiment where the detection component 13 includes a distance sensor 131, the distance sensor 131 is mounted on the mounting plate 12. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter 111. Under the action of this force, the mounting base 112 will rotate relative to the mounting bracket 16. Therefore, the first end 1121 will move downward in the Z direction, and the second end 1122 will move upward in the Z direction. After the mounting base 112 rotates, the distance sensor 131 can detect that the distance between the mounting base 112 and the distance sensor 131 increases, thereby determining that the cutter 111 has touched the roller surface 3, and can stop moving the cutter 111 to avoid the cutter 111 scratching the roller surface 3.

[0060] like Figure 3As shown, in the embodiment where the detection component 13 includes a pressure sensor 132, the pressure sensor 132 is mounted on the mounting plate 12. One end of the elastic member 14 is connected to the side of the first end 1121 near the mounting plate 12, and the other end of the elastic member 14 is connected to the pressure sensor 132. That is, the elastic member 14 and the cutter 111 are both located at the first end 1121. When the cutter 111 contacts the roller surface 3, it can compress the elastic member 14. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter 111. Under the action of this force, the mounting base 112 will rotate relative to the mounting bracket 16. Therefore, the first end 1121 will move downward in the Z direction, and the second end 1122 will move upward in the Z direction. After the mounting base 112 rotates, the elastic element 14 will be subjected to this force. Therefore, the pressure sensor 132 connected to one end of the elastic element 14 can detect that the elastic element 14 has been subjected to a force, and thus it can be determined that the cutter 111 has touched the roller surface 3. The cutter 111 can then be stopped from moving to avoid the cutter 111 scratching the roller surface 3.

[0061] like Figure 1 As shown, in the embodiment where the detection component 13 includes a power supply component 133 and a conductive rod 134, one end of the power supply component 133 is connected to the conductive rod 134, and the other end of the power supply component 133 is connected to the mounting base 112. When the cutter 111 is in contact with the roller surface 3, the second end 1122 of the mounting base 112 abuts against the conductive rod 134. Therefore, the mounting base 112, the conductive rod 134, and the power supply component 133 form a circuit. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts an effect on the cutter 111. Under the force, the mounting base 112 will rotate relative to the mounting bracket 16. Therefore, the first end 1121 will move downward in the Z direction and the second end 1122 will move upward in the Z direction, thereby separating the mounting base 112 from the conductive rod 134. As a result, the circuit formed by the mounting base 112, the conductive rod 134 and the power supply component 133 will be broken. Thus, it can be determined that the cutter 111 has touched the roller surface 3, and the movement of the cutter 111 can be stopped to avoid the cutter 111 scratching the roller surface 3.

[0062] In an optional embodiment, the cutting mechanism 1 further includes a limiting rod 15, which is disposed on the mounting plate 12, and the second end 1122 of the mounting base 112 can abut or separate from the limiting rod 15.

[0063] like Figure 2 and Figure 3As shown, when the cutter 111 is not in contact with the roller surface 3, the second end 1122 of the mounting base 112 abuts against the limiting rod 15. Specifically, the elastic element 14 exerts an upward force along the Z direction on the first end 1121 of the mounting base 112. Since the mounting base 112 is rotatably connected to the mounting bracket 16, the first end 1121 moves upward along the Z direction, and the second end 1122 moves downward along the Z direction. The limiting rod 15 can restrict the second end 1122 of the mounting base 112 from moving downward along the Z direction, thus keeping the mounting base 112 in a preset position. When the cutter 111 contacts the roller surface 3, the second end 1122 of the mounting base 112 separates from the limiting rod 15.

[0064] In one optional embodiment, the cutter assembly 11 includes a cutter 111 and a mounting base 112, the cutter 111 being disposed on the side of the mounting base 112 facing away from the mounting plate 12; the cutter mechanism 1 further includes a mounting base 112 bracket, the mounting bracket 16 being disposed on the mounting plate 12, a cavity 161 being formed between the mounting bracket 16 and the mounting plate 12, the mounting bracket 16 having a through hole 162 communicating with the cavity 161, the elastic member 14 being located in the cavity 161, and the mounting base 112 being connected to the elastic member 14 through the through hole 162.

[0065] like Figures 4-6 As shown, the cutter assembly 11 includes a cutter 111 and a mounting base 112. The cutter 111 is disposed on the mounting base 112, and the mounting base 112 provides a mounting position for the cutter 111.

[0066] Further explanation: the cutting mechanism 1 also includes a mounting bracket 16; wherein, the mounting bracket 16 is disposed on the mounting plate 12, and the end of the mounting bracket 16 facing the mounting plate 12 has a groove, forming a cavity 161 between the groove of the mounting bracket 16 and the mounting plate 12, and a through hole 162 is formed on the mounting bracket 16, the through hole 162 communicating with the cavity 161, the elastic element 14 is located in the cavity 161, the mounting seat 112 passes through the through hole 162, the elastic element 14 connects the mounting seat 112 and the mounting plate 12, the cutter 111 is disposed on the side of the mounting seat 112 away from the mounting plate 12, the mounting seat 112 can move axially along the through hole 162, so when the cutter 111 contacts the roller surface 3, the mounting seat 112 can move downward in the Z direction to compress the elastic element 14, and the through hole 162 can provide a guiding function for the mounting seat 112.

[0067] like Figure 6As shown, in the embodiment where the detection component 13 includes a distance sensor 131, the distance sensor 131 is located in the cavity 161 and is mounted on the mounting plate 12. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter 111. Under the action of this force, the mounting base 112 will move downward in the Z direction. The distance sensor 131 can detect the decrease in the distance between the mounting base 112 and the distance sensor 131, thereby determining that the cutter 111 has touched the roller surface 3, and can stop moving the cutter 111 to avoid the cutter 111 scratching the roller surface 3.

[0068] like Figure 5 As shown, in the embodiment where the detection component 13 includes a pressure sensor 132, the pressure sensor 132 is disposed in the cavity 161 and on the mounting plate 12. One end of the elastic element 14 is connected to the mounting base 112, and the other end of the elastic element 14 is connected to the pressure sensor 132. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter 111. Under the action of this force, the mounting base 112 will move downward in the Z direction, thereby compressing the elastic element 14. The elastic element 14 will be subjected to this force, so the pressure sensor 132 connected to one end of the elastic element 14 can detect that the elastic element 14 has been subjected to a force, thereby determining that the cutter 111 has touched the roller surface 3, and can stop the cutting 111 to avoid the cutter 111 scratching the roller surface 3.

[0069] like Figure 4 As shown, in the embodiment where the detection component 13 includes a power supply component 133 and a conductive rod 134, one end of the power supply component 133 is connected to the conductive rod 134, and the other end of the power supply component 133 is connected to the mounting base 112. When the cutter 111 is not in contact with the roller surface 3, the mounting base 112 is disconnected from the conductive rod 134. When the cutter 111 contacts the roller surface 3, the roller surface 3 exerts a force on the cutter 111, and the mounting base 112 moves downward in the Z direction under the action of this force. The mounting base 112 then contacts the conductive rod 134, thereby forming a circuit with the mounting base 112, the conductive rod 134, and the power supply component 133. This allows it to be determined that the cutter 111 has touched the roller surface 3, and the movement of the cutter 111 can be stopped to avoid the cutter 111 scratching the roller surface 3.

[0070] The power supply component 133 includes a battery, a first wire, and a second wire. The first wire connects the positive terminal of the battery to the conductive rod 134, and the second wire connects the negative terminal of the battery to the mounting base 112. Alternatively, the power supply component 133 includes a battery, with the positive terminal of the battery connected to the conductive rod 134 and the negative terminal of the battery connected to the mounting base 112.

[0071] The mounting base 112 may be made of a conductive material; or, the mounting base 112 may include a first mounting part and a second mounting part, with the cutter 111 disposed in the first mounting part, the first mounting part being made of an insulating material, and the power supply component 133 being connected to the second mounting part, the second mounting part being made of a conductive material.

[0072] like Figures 1-6 As shown, in an optional embodiment, the cutting device further includes a drive mechanism 2, which is connected to the cutting mechanism 1 and can drive the cutting mechanism 1 to move. Specifically, the drive mechanism 2 can drive the cutting mechanism 1 to move closer to or further away from the roller surface 3. When the cutter contacts the roller surface 3, the drive mechanism 2 stops driving the cutting mechanism 1 to move.

[0073] In one optional embodiment, the driving mechanism 2 includes a driving component 21, a fixed base 22, a first sliding part 23, and a second sliding part 24; the driving end of the driving component 21 is connected to the cutting mechanism 1, and the driving component 21 can drive the cutting mechanism 1 to move; the driving component 21 is disposed on the fixed base 22; the first sliding part 23 is connected to the cutting mechanism 1, and the second sliding part 24 is disposed on the fixed base 22, and the first sliding part 23 and the second sliding part 24 are slidably connected.

[0074] like Figures 1-6 As shown, the drive mechanism 2 includes a drive assembly 21, a fixed base 22, a first sliding part 23, and a second sliding part 24. The drive end of the drive assembly 21 is connected to the cutter mechanism 1. Specifically, the drive end of the drive assembly 21 is connected to the side of the mounting plate 12 away from the cutter assembly 11. The drive assembly 21 can drive the cutter mechanism 1 towards or away from the roller surface 3. The drive assembly 21 is mounted on the fixed base 22, which provides a mounting position for the drive assembly 21, making it more stable during operation. The first sliding part 23 is connected to the cutter mechanism 1, and the second sliding part 24 is mounted on the fixed base 22. The first sliding part 23 and the second sliding part 24 are slidably connected. When the drive assembly 21 drives the cutter mechanism 1 to move, the first sliding part 23 slides relative to the second sliding part 24, thereby providing a guiding effect for the cutter mechanism 1 and preventing the cutter mechanism 1 from deviating during movement.

[0075] like Figures 1-6 As shown, in one specific embodiment, the first sliding part 23 is a guide rod; the second sliding part 24 is a guide hole. The guide hole is opened on the fixed base 22. One end of the guide rod is connected to the mounting plate 12 of the cutter mechanism 1. The guide rod passes through the guide hole and can slide along the guide hole. Therefore, when the drive assembly 21 drives the cutter mechanism 1 to move, the guide rod will slide along the guide hole, thereby providing a guiding function for the cutter mechanism 1.

[0076] In another specific embodiment, the first sliding part 23 is a slider, and the second sliding part 24 is a guide rail. The slider is connected to the cutting mechanism 1, and the guide rail is set on the fixed base 22. The slider is slidably connected to the guide rail. When the driving component 21 drives the cutting mechanism 1 to move, the slider moves along the guide rail, thereby providing guidance for the cutting mechanism 1.

[0077] The drive component 21 can be a linear motor, hydraulic cylinder, electric cylinder or pneumatic cylinder.
