Description

Technical Field

[0001] This application relates to the technical field of batteries, and particularly to a cutting device and a cutting system. Background Art

[0002] Energy conservation and emission reduction are the keys to sustainable development, which has promoted the adjustment of the energy structure and the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology. Due to its advantages such as high energy density, good cycling ability, high working voltage, environmental friendliness, and low self-discharge, it has been widely used in portable electronics, electric vehicles, and energy storage systems.

[0003] During the manufacturing process of batteries, it is necessary to coat a film layer on the battery electrode sheet and cut and sample the coated battery electrode sheet to detect whether the coating of the film layer is qualified. However, at present, cutting and sampling are mainly carried out manually, with low efficiency, poor stability, and prone to problems such as injuries to operators. Summary of the Utility Model

[0004] The main purpose of this application is to provide a cutting device and a cutting system, aiming to solve the above technical problems existing in the prior art.

[0005] To solve the above problems, this application provides a cutting device. The cutting device includes a first driving member, a loading platform, and a cutting assembly. The loading platform is used to carry the workpiece to be processed; the cutting assembly is connected to the first driving member. The cutting assembly includes a pressing shell, a rotary cutting member, and a second driving member. The first driving member is used to drive the pressing shell to approach the loading platform along a first direction so that the pressing shell presses the workpiece to be processed. The first driving member is used to drive the rotary cutting member to approach the loading platform along the first direction, and the second driving member is used to drive the rotary cutting member to rotate to cut the workpiece to be processed. Thus, the first driving member can drive the pressing shell to press the workpiece to be processed, thereby fixing the workpiece to be processed and improving the cutting stability. The first driving member can also drive the rotary cutting member to approach the loading platform. The second driving member drives the rotary cutting member to rotate, so that the rotary cutting member rotates to cut the workpiece to be processed, improving the automation degree of cutting the workpiece to be processed, thereby improving the cutting efficiency of the rotary cutting member. At the same time, the pressure distribution during rotary cutting is uniform, the cut edge is smoother and neater, the consistency of the cut workpieces is better, and the risk of damaging the workpiece to be processed due to scratching during cutting can be alleviated.

[0006] In some embodiments, the first driving member and the second driving member are connected, and the cutting assembly includes an elastic member. The elastic member elastically supports between the pressing shell and the second driving member. Thus, the first driving member only needs to be connected to the second driving member, and the pressing shell can be driven to approach the loading platform along the first direction through the elastic member, so that the pressing shell and the rotary cutting member move relatively, reducing the structural complexity of the cutting device.

[0007] In some embodiments, in a state where the pressing shell is spaced from the workpiece to be processed, the distance between the end of the pressing shell away from the second driving member and the carrier table is smaller than the distance between the end of the rotary cutting member away from the second driving member and the carrier table. Thus, in a state where no processing work is carried out or no cutting is performed, the rotary cutting member is farther away from the carrier table than the pressing shell, reducing the risk of damage to the carrier table, the workpiece to be processed, and the rotary cutting member caused by the rotary cutting member contacting the carrier table or the workpiece to be processed. At the same time, it is convenient for the pressing shell to contact the workpiece to be processed prior to the rotary cutting member to press the workpiece to be processed, thereby improving the cutting stability.

[0008] In some embodiments, in a state where the pressing shell presses the workpiece to be processed, the first driving member drives the second driving member to drive the rotary cutting member to move in a first direction, and the pressing shell compresses the elastic member through the carrier table and the second driving member. Thus, in a state where the pressing shell presses the workpiece to be processed, the elastic member is compressed under the extrusion of the pressing shell and the second driving member, enabling the first driving member to drive the second driving member to drive the rotary cutting member to continue moving in the first direction, thereby facilitating the rotary cutting member to contact the workpiece to be processed to cut the workpiece to be processed, further improving the stability of the rotary cutting member in cutting the workpiece to be processed and the cutting effect of the rotary cutting member.

[0009] In some embodiments, the cutting assembly includes a rotating shaft connected between the second driving member and the rotary cutting member, and the elastic member is sleeved outside the rotating shaft. Thus, the second driving member can drive the rotary cutting member to move in the first direction through the rotating shaft, and drive the rotary cutting member to rotate to cut the workpiece to be processed, thereby facilitating the rotating shaft to cooperate with the elastic member to cause relative movement between the pressing shell and the rotary cutting member, reducing the structural complexity of the cutting device, and at the same time improving the cutting stability of the rotary cutting member.

[0010] In some embodiments, the rotary cutting member is provided with an air cavity and an air inlet. The opening of the air cavity faces the carrier table, the air inlet communicates with the air cavity, and the air inlet is used to communicate with an air pipe. Thus, the air pressure in the air cavity can be controlled through the air pipe and the air inlet, so as to adsorb or release the cut workpiece through the air cavity, facilitating the transfer of the workpiece and improving the flexibility of the cutting device.

[0011] In some embodiments, the pressing shell is provided with a receiving groove. The opening of the receiving groove faces the carrier table, and the rotary cutting member is located in the receiving groove. Thus, the rotary cutting member can be accommodated through the receiving groove, facilitating the pressing shell to provide protection for the rotary cutting member, reducing the risk of damage to the rotary cutting member, and improving the protection effect on the staff, reducing the risk of injury to the staff caused by contacting the rotary cutting member.

[0012] In some embodiments, an avoidance opening is provided on the side wall of the accommodation groove. The avoidance opening corresponds to the air inlet, and the avoidance opening is used to avoid the air pipe so that the air pipe is communicated with the air inlet. Thus, the air pipe can be communicated with the air cavity through the avoidance opening and the air inlet, so as to control the air pressure in the air cavity through the air pipe. The structure is simple, and the flexibility of the cutting device is improved.

[0013] In some embodiments, the cutting device includes a third driving member, a slideway and a sliding member. The sliding member is connected to the slideway, and the first driving member is connected to the sliding member. The third driving member is used to drive the sliding member to move along a second direction perpendicular to the first direction on the slideway. Thus, the third driving member can drive the sliding member to move along the second direction on the slideway to drive the first driving member to move in the second direction, so as to facilitate adjusting the position of the rotary cutting member in the second direction and improve the cutting flexibility of the cutting device.

[0014] In some embodiments, the cutting device includes a collection box. The collection box is arranged adjacent to the loading platform. The third driving member is used to drive the sliding member to move along the second direction on the slideway so that the cutting assembly moves between a first position and a second position. Wherein, at the first position, the rotary cutting member is arranged opposite to the loading platform in the first direction, and at the second position, the rotary cutting member is arranged opposite to the collection box in the first direction. Thus, at the first position, the rotary cutting member cuts the workpiece to be processed and can capture the cut workpiece. The third driving member further drives the rotary cutting member to be arranged opposite to the collection box at the second position, so that the rotary cutting member can transfer the cut workpiece to the collection box, thereby facilitating the collection and storage of the cut workpiece through the collection box and improving the automation degree and collection efficiency of the cutting device.

[0015] To solve the above problems, the present application also provides a cutting system, and the cutting system includes a workpiece to be processed and the above-mentioned cutting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Currently, from the perspective of the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of batteries, the market demand is also continuously increasing.

[0032] During the manufacturing process of batteries, it is necessary to coat a film layer on the battery electrode sheet and cut and sample the coated battery electrode sheet to detect whether the coating of the film layer is qualified. However, currently, cutting and sampling are mainly carried out manually, with low efficiency, poor stability, and prone to problems such as injuries to operators.

[0033] To solve the technical problems existing in the related art, a cutting device and a cutting system are provided. Among them, the cutting device can drive a cutting assembly through a first driving member, so that a pressing shell in the cutting assembly presses a workpiece to be processed on a loading table, improving the cutting stability. And a second driving member in the cutting assembly can drive a rotary cutting member to rotate and cut the workpiece to be processed, thereby realizing automatic cutting of the workpiece to be processed. At the same time, the cutting efficiency and effect are effectively improved by means of rotary cutting.

[0034] A battery generally may include a box body and battery cells, and the battery cells are accommodated in the box body. In a battery, there may be multiple battery cells, and the multiple battery cells may be connected in series, in parallel, or in a series-parallel combination. A series-parallel combination means that there are both series and parallel connections among the multiple battery cells. The multiple battery cells may be directly connected in series, in parallel, or in a series-parallel combination together, and then the whole formed by the multiple battery cells is accommodated in the box body; of course, the battery may also be in the form that multiple battery cells are first connected in series, in parallel, or in a series-parallel combination to form battery modules, and then multiple battery modules are connected in series, in parallel, or in a series-parallel combination to form a whole and are accommodated in the box body. The battery may also include other structures. For example, the battery may further include a busbar component for realizing the electrical connection among the multiple battery cells.

[0035] The manufacturing methods of battery cells include the stacking type and the winding type, that is, battery cells are divided into two types: stacked batteries and wound batteries. Stacked batteries have a uniform current collection effect, a relatively small internal resistance of the battery, and a large specific power. However, in order to improve the accuracy, extremely high requirements are imposed on the mold accuracy, the equipment investment is high, and the process is relatively complex, resulting in low production efficiency. Wound batteries are simple to manufacture, and the requirements for equipment accuracy in the processes of sheet production and assembly are generally average, with high production efficiency and low costs. In terms of performance, wound batteries have excellent high and low temperature performance, can be charged very quickly, have an extremely long service life, a stable high output voltage, and a strong and earthquake-resistant structure.

[0036] A battery cell refers to the smallest unit that makes up a battery. A battery cell may include a housing, an electrode assembly, and other functional components. The electrode assembly is the component in the battery cell where an electrochemical reaction occurs. The housing may contain one or more electrode assemblies. The electrode assembly is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and usually an isolation member is provided between the positive electrode sheet and the negative electrode sheet.

[0037] The electrode sheet can be a positive electrode sheet or a negative electrode sheet. The part of the electrode sheet with active material constitutes the main body of the electrode assembly, and the parts of the electrode sheet without active material respectively constitute the electrode tabs. During the charging and discharging process of the battery, the active material reacts with the electrolyte, and the electrode tabs are connected to the electrode terminals to form a current loop. The active material can be coated on the electrode sheet in the form of a slurry to form a film layer on the electrode sheet, and then the film layer can be fixed on the electrode sheet by means such as baking and rolling. Among them, the materials of the slurry can include but are not limited to lithium-containing phosphates, lithium transition metal oxides and their respective modified compounds, artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based materials, tin-based materials, and lithium titanate, etc.

[0038] This application provides a cutting device. Please refer to Figures 1 - 3 , Figure 1 which is the first schematic structural diagram of the cutting device according to one or more embodiments of this application; Figure 2 which is the second schematic structural diagram of the cutting device according to one or more embodiments of this application; Figure 3 which is according to Figure 2 the schematic cross-sectional view of the cutting device shown along the A-A direction.

[0039] The cutting device includes a first driving member 10, a loading platform 20, and a cutting assembly 30. The loading platform 20 is used to carry the workpiece to be processed 2; the cutting assembly 30 is connected to the first driving member 10. The cutting assembly 30 includes a pressing shell 31, a rotary cutting member 32, and a second driving member 33. The first driving member 10 is used to drive the pressing shell 31 to approach the loading platform 20 along the first direction x1 so that the pressing shell 31 presses the workpiece to be processed 2. The first driving member 10 is used to drive the rotary cutting member 32 to approach the loading platform 20 along the first direction x1, and the second driving member 33 is used to drive the rotary cutting member 32 to rotate to cut the workpiece to be processed 2.

[0040] The workpiece to be processed 2 can be a battery electrode sheet, etc. The cutting device 1 can cut the workpiece to be processed 2, so as to cut out a cut workpiece from the workpiece to be processed 2. Exemplarily, the workpiece to be processed 2 is a battery electrode sheet, and a film layer is coated on the battery electrode sheet. The cutting device 1 can cut out a part on the battery electrode sheet so as to use the cut part of the battery electrode sheet as a sample for detection, thereby judging whether the battery electrode sheet is qualified. Among them, the cut workpiece refers to the part cut and separated from the workpiece to be processed 2 by the cutting device 1.

[0041] The stage 20 is used to carry the workpiece 2 to be processed, thereby providing support for the workpiece 2 to be processed. The cutting assembly 30 is connected to the first driving member 10. The first driving member 10 can drive the cutting assembly 30 to move. The first driving member 10 can be directly or indirectly connected to the pressing shell 31 and the rotary cutting member 32. The first driving member 10 can include, but is not limited to, a cylinder, a motor, a hydraulic cylinder, and the like. The cutting assembly 30 includes a pressing shell 31. The shape of the pressing shell 31 can be any shape including, but not limited to, a circle, a square, and the like. The first driving member 10 can drive the pressing shell 31 to approach the stage 20 along the first direction x1 so that the pressing shell 31 presses the workpiece 2 to be processed, causing the pressing shell 31 to hold the workpiece 2 to be processed on the stage 20, thereby improving the stability of the workpiece 2 to be processed. It can be understood that in some application scenarios, when the cutting device 1 is in an unprocessed working state, the pressing shell 31 can be spaced from the workpiece 2 to be processed to reduce the influence of the pressing shell 31 on the workpiece 2 to be processed, enabling the workpiece 2 to move relative to the carrying platform, thereby facilitating the adjustment of the relative positions of the workpiece 2 to be processed, the stage 20, and the cutting assembly 30. When the cutting device 1 is in a processing working state, the first driving member 10 drives the pressing shell 31 to press the workpiece 2 to be processed, thereby fixing the workpiece 2 to be processed for cutting the workpiece 2 to be processed. The first driving member 10 is also used to drive the rotary cutting member 32 to approach the stage 20 along the first direction x1 so that the rotary cutting member 32 contacts the workpiece 2 to be processed, and the rotary cutting member 32 can be driven to rotate by the second driving member 33, thereby cutting the workpiece 2 to be processed. The second driving member 33 can include, but is not limited to, a motor, a rotary cylinder, a hydraulic driving member, and the like. The rotary cutting member 32 can be located inside or outside the pressing shell 31. The rotary cutting member 32 can be a rotary blade or the like. The shape of the rotary cutting member 32 can include, but is not limited to, a circle and the like. Exemplarily, the rotary cutting member 32 can be a circular cutter, and the second driving member 33 can drive the circular cutter to rotate to cut out a circular cut workpiece from the workpiece 2 to be processed.

[0042] In some application scenarios, when the cutting device 1 is in the unprocessed working state, both the pressing shell 31 and the rotary cutting member 32 are spaced from the workpiece to be processed 2. When the cutting device 1 is in the processing working state, the first driving member 10 drives the pressing shell 31 and the rotary cutting member 32 to approach the carrier table 20 along the first direction x1, so that the pressing shell 31 cooperates with the carrier to press the workpiece to be processed 2, and facilitates the contact between the rotary cutting member 32 and the workpiece to be processed 2. The second driving member 33 drives the rotary cutting member 32 to rotate to cut the workpiece to be processed 2. After the cutting is completed, the first driving member 10 can also drive the pressing shell 31 and the rotary cutting member 32 to move away from the carrier table 20 along the opposite direction of the first direction x1 to release the workpiece to be processed 2. In some other embodiments, the cutting device 1 may further include a backing plate, which can be located between the carrier table 20 and the workpiece to be processed 2. The backing plate can cooperate with the carrier table 20 to provide support for the workpiece to be processed 2, and is used to contact the rotary cutting member 32 during the process of the rotary cutting member 32 cutting the workpiece to be processed 2, thereby alleviating the risk of damage to the rotary cutting member 32 and the carrier table 20 caused by the direct contact between the rotary cutting member 32 and the carrier table 20.

[0043] Through the above implementation manner, the first driving member 10 can be used to drive the pressing shell 31 to press the workpiece to be processed 2, thereby fixing the workpiece to be processed 2 and improving the cutting stability. The first driving member 10 can also drive the rotary cutting member 32 to approach the carrier table 20, and the second driving member 33 drives the rotary cutting member 32 to rotate, so that the rotary cutting member 32 rotates to cut the workpiece to be processed 2, improving the automation degree of cutting the workpiece to be processed 2, thereby improving the cutting efficiency of the rotary cutting member 32. At the same time, the pressure distribution during rotary cutting is uniform, the cut edge is smoother and neater, the consistency of the cut workpieces is better, and the risk of damage to the workpiece to be processed 2 caused by scratching the workpiece to be processed 2 during the cutting process can be alleviated.

[0044] In some embodiments, the first driving member 10 is connected to the second driving member 33. The cutting assembly 30 includes an elastic member 34, and the elastic member 34 elastically supports between the pressing shell 31 and the second driving member 33. The elastic member 34 may include, but is not limited to, a spring, etc. It can be understood that the elastic member 34 can be compressed or stretched. Exemplarily, the first driving member 10 is connected to the second driving member 33, and the second driving member 33 and the pressing shell 31 are elastically connected through the elastic member 34. The first driving member 10 can drive the second driving member 33 to move in the first direction x1, thereby indirectly driving the pressing shell 31 and the rotary cutting member 32 to move in the first direction x1. It should be noted that compared with the rigid connection between the pressing shell 31 and the second driving member 33, the elastic member 34 elastically supports between the pressing shell 31 and the second driving member 33, so that the pressing shell 31 can move relative to the second driving member 33 through the compression or stretching of the elastic member 34, thereby enabling the pressing shell 31 to move relative to the rotary cutting member 32. Thus, the first driving member 10 only needs to be connected to the second driving member 33, and can drive the pressing shell 31 to approach the loading platform 20 along the first direction x1 through the elastic member 34, so that the pressing shell 31 moves relative to the rotary cutting member 32, reducing the structural complexity of the cutting device 1.

[0045] In some embodiments, in a state where the pressing shell 31 is spaced from the workpiece 2 to be processed, the distance between the end of the pressing shell 31 away from the second driving member 33 and the loading platform 20 is less than the distance between the end of the rotary cutting member 32 away from the second driving member 33 and the loading platform 20. It can be understood that when the cutting device 1 is in a state of not performing processing work or not in a cutting state, both the pressing shell 31 and the rotary cutting member 32 can be spaced from the workpiece 2 to be processed. By making the distance between the end of the pressing shell 31 away from the second driving member 33 and the loading platform 20 less than the distance between the end of the rotary cutting member 32 away from the second driving member 33 and the loading platform 20, the rotary cutting member 32 is farther from the loading platform 20 than the pressing shell 31. During the process of the first driving member 10 driving the second driving member 33 to approach the loading platform 20, it is convenient for the pressing shell 31 to contact the workpiece 2 to be processed before the rotary cutting member 32, so that the pressing shell 31 first presses to improve the stability of the workpiece 2 to be processed, and then the rotary cutting member 32 cuts the workpiece 2 to be processed, improving the cutting stability. Thus, in a state of not performing processing work or not in a cutting state, the rotary cutting member 32 can be made farther from the loading platform 20 than the pressing shell 31, reducing the risk of damage to the loading platform 20, the workpiece 2 to be processed, and the rotary cutting member 32 caused by the rotary cutting member 32 contacting the loading platform 20 or the workpiece 2 to be processed. At the same time, it is convenient for the pressing shell 31 to contact the workpiece 2 to be processed before the rotary cutting member 32 to press the workpiece 2 to be processed, thereby improving the cutting stability.

[0046] In some embodiments, in a state where the pressing housing 31 presses the workpiece 2 to be processed, the first driving member 10 drives the second driving member 33 to drive the rotary cutting member 32 to move along the first direction x1, and the pressing housing 31 compresses the elastic member 34 through the carrier table 20 and the second driving member 33. Specifically, when the cutting device 1 is in a processing working state, the first driving member 10 can directly drive the second driving member 33 to approach the carrier table 20 in the first direction x1, and indirectly drive the pressing housing 31 and the rotary cutting member 32 to approach the carrier table 20 in the first direction x1. It can be understood that in a state where the pressing housing 31 presses on the workpiece 2 to be processed, the pressing housing 31 stops approaching the carrier table 20 under the obstruction of the workpiece 2 to be processed, and the workpiece 2 to be processed has a thickness in the first direction x1. After the rotary cutting member 32 contacts the workpiece 2 to be processed, it will rotate and cut the workpiece 2 to be processed under the drive of the second driving member 33, and needs to approach the carrier table 20 further compared with the pressing housing 31 to penetrate the surface of the workpiece 2 to be processed to complete the cutting. Therefore, in a state where the pressing housing 31 presses on the workpiece 2 to be processed, the pressing housing 31 compresses the elastic member 34 through the carrier table 20 and the second driving member 33, causing relative movement between the second driving member 33 and the pressing housing 31, continuing to approach the carrier table 20, and driving the rotary cutting member 32 to approach the carrier table 20 further, so as to facilitate the rotary cutting member 32 to complete the cutting of the workpiece 2 to be processed. Further, after the cutting is completed, the first driving member 10 can directly drive the second driving member 33 to leave the carrier table 20 in the opposite direction of the first direction x1, and the elastic member 34 can rebound and recover to drive the pressing housing 31 to leave the carrier table 20. Thus, in a state where the pressing housing 31 presses the workpiece 2 to be processed, the elastic member 34 is compressed under the extrusion of the pressing housing 31 and the second driving member 33, enabling the first driving member 10 to drive the second driving member 33 to drive the rotary cutting member 32 to continue to move along the first direction x1, so as to facilitate the rotary cutting member 32 to contact the workpiece 2 to be processed to cut the workpiece 2 to be processed, further improving the stability of the rotary cutting member 32 in cutting the workpiece 2 to be processed and the cutting effect of the rotary cutting member 32.

[0047] In some embodiments, the cutting assembly 30 includes a rotating shaft 35. The rotating shaft 35 is connected between the second driving member 33 and the rotary cutting member 32. The elastic member 34 is sleeved outside the rotating shaft 35. The second driving member 33 can drive the rotating shaft 35 to rotate and drive the rotary cutting member 32 to rotate. The elastic member 34 is sleeved outside the rotating shaft 35, facilitating relative movement between the pressing housing 31 and the second driving member 33 in the first direction x1 when the second driving member 33 and the pressing housing 31 compress the elastic member 34. The second driving member 33 is relatively fixed to the rotary cutting member 32 in the first direction x1 through the rotating shaft 35, thus facilitating relative movement between the rotary cutting member 32 and the pressing housing 31. Thereby, the second driving member 33 can drive the rotary cutting member 32 to move along the first direction x1 through the rotating shaft 35 and drive the rotary cutting member 32 to rotate to cut the workpiece to be processed 2, thus facilitating the rotating shaft 35 to cooperate with the elastic member 34 to cause relative movement between the pressing housing 31 and the rotary cutting member 32, reducing the structural complexity of the cutting device 1 and improving the cutting stability of the rotary cutting member 32.

[0048] In some embodiments, the rotary cutting member 32 is provided with an air cavity 36 and an air inlet 37. The opening of the air cavity 36 faces the carrier table 20. The air inlet 37 communicates with the air cavity 36, and the air inlet 37 is used to communicate with the air pipe 80. The air pipe 80 communicates with the air cavity 36 through the air inlet 37, thus facilitating filling or extracting gas into the air cavity 36 through the air pipe 80 to control the air pressure in the air cavity 36. The opening of the air cavity 36 faces the carrier table 20. It can be understood that after the rotary cutting member 32 cuts the workpiece from the workpiece to be processed 2, the cut workpiece is located at the opening of the air cavity 36. The gas in the air cavity 36 can be extracted through the air pipe 80 to make the air cavity 36 have a negative pressure relative to the outside, thereby adsorbing the cut workpiece to the air cavity 36 and enabling the cutting device 1 to capture the cut workpiece. Further, gas can also be filled into the air cavity 36 through the air pipe 80 to make the air pressure in the air cavity 36 the same as or have a positive pressure relative to the outside, thereby releasing the cut workpiece. In some application scenarios, after the rotary cutting member 32 completes cutting, the cut workpiece can be captured through the air cavity 36. The first driving member 10 drives the rotary cutting member 32 to leave the carrier table 20 in the opposite direction of the first direction x1, thereby driving the cut workpiece to leave the carrier table 20, and further facilitating the transfer of the cut workpiece. Thereby, the air pressure in the air cavity 36 can be controlled through the air pipe 80 and the air inlet 37, so as to adsorb or release the cut workpiece through the air cavity 36, facilitate the transfer of the cut workpiece, and improve the flexibility of the cutting device 1.

[0049] In some embodiments, the pressing housing 31 is provided with a receiving groove 311. The opening of the receiving groove 311 faces the loading platform 20, and the rotary cutting member 32 is located within the receiving groove 311. The receiving groove 311 can provide protection for the rotary cutting member 32, and the rotary cutting member 32 can contact the workpiece to be processed 2 through the opening of the receiving groove 311. In some application scenarios, in a state where the pressing housing 31 is spaced apart from the workpiece to be processed 2, the distance between the end of the pressing housing 31 away from the second driving member 33 and the loading platform 20 is less than the distance between the end of the rotary cutting member 32 away from the second driving member 33 and the loading platform 20. Thus, in a state where the pressing housing 31 is spaced apart from the workpiece to be processed 2, it is convenient for the rotary cutting member 32 to be completely located within the receiving groove, improving the protection effect of the pressing housing 31 on the rotary cutting member 32. Further, it is also convenient to isolate the rotary cutting member 32 from the staff through the pressing housing 31, reducing the risk of the staff directly contacting the rotary cutting member 32. Therefore, the rotary cutting member 32 can be received by the receiving groove 311, facilitating the pressing housing 31 to provide protection for the rotary cutting member 32, alleviating the risk of damage to the rotary cutting member 32, and improving the protection effect on the staff, reducing the risk of injury to the staff caused by contacting the rotary cutting member 32.

[0050] In some embodiments, the side wall of the receiving groove 311 is provided with an avoidance opening 3111. The avoidance opening 3111 corresponds to the air inlet 37, and the avoidance opening 3111 is used to avoid the air pipe 80 so that the air pipe 80 communicates with the air inlet 37. Exemplarily, the air pipe 80 can sequentially communicate with the air cavity 36 through the avoidance opening 3111 and the air inlet 37, reducing the risk of interference between the air pipe 80 and the pressing housing 31. Therefore, the air pipe 80 can be made to communicate with the air cavity 36 through the avoidance opening 3111 and the air inlet 37, so as to control the air pressure in the air cavity 36 through the air pipe 80. The structure is simple and the flexibility of the cutting device 1 is improved.

[0051] Combined Figures 4 - 5 , Figure 4 is a third structural schematic diagram of a cutting device according to one or more embodiments of the present application; Figure 5 is a fourth structural schematic diagram of a cutting device according to one or more embodiments of the present application.

[0052] In some embodiments, the cutting device 1 includes a third driving member 40, a slideway 50, and a sliding member 60. The sliding member 60 is connected to the slideway 50, and the first driving member 10 is connected to the sliding member 60. The third driving member 40 is configured to drive the sliding member 60 to move along a second direction x2 perpendicular to the first direction x1 on the slideway 50. The third driving member 40 may include, but is not limited to, a motor, a cylinder, a hydraulic driving member, and the like. The slideway 50 may include, but is not limited to, a slide rail, a lead screw, a conveyor belt, a conveyor chain, and the like. The sliding member 60 is connected to the slideway 50, and the third driving member 40 can drive the sliding member 60 to move along the second direction x2 on the slideway 50. The first driving member 10 is connected to the sliding member 60, so that the sliding member 60 drives the first driving member 10 to move in the second direction x2, and further drives the cutting assembly 30 to move in the second direction x2 through the first driving member 10. It can be understood that the workpiece 2 to be processed may have a certain width in the second direction x2. Through the third driving member 40, the slideway 50, and the sliding member 60, the first driving member 10 can be driven to move in the second direction x2, and finally the rotary cutting member 32 can be driven to move in the second direction x2, so that the position of the rotary cutting member 32 can be adjusted to cut different positions of the workpiece 2 in terms of width dimension. Thus, the third driving member 40 can be used to drive the sliding member 60 to move along the second direction x2 on the slideway 50 to drive the first driving member 10 to move in the second direction x2, so as to facilitate the adjustment of the position of the rotary cutting member 32 in the second direction x2 and improve the cutting flexibility of the cutting device 1.

[0053] In some embodiments, the cutting device 1 includes a collection box 70 which is adjacently arranged to the loading platform 20. The third driving member 40 is configured to drive the sliding member 60 to move along the second direction x2 on the slideway 50 so as to move the cutting assembly 30 between a first position and a second position. Wherein, at the first position, the rotary cutting member 32 is oppositely arranged to the loading platform 20 in the first direction x1, and at the second position, the rotary cutting member 32 is oppositely arranged to the collection box 70 in the first direction x1. The collection box 70 can be used to accommodate the cut workpieces cut by the rotary cutting member 32. It can be understood that at the first position, the rotary cutting member 32 can cut the workpiece to be processed 2 on the loading platform 20 and capture the cut workpieces, and at the second position, the rotary cutting member 32 can release the captured cut workpieces to transfer the cut workpieces into the collection box 70. Exemplarily, the collection box 70 may be formed with a receiving cavity which can communicate with the outside through an opening. That the rotary cutting member 32 is oppositely arranged to the collection box 70 in the first direction x1 at the second position may mean that the rotary cutting member 32 is oppositely arranged to the opening of the collection box 70, thus facilitating the movement of the cut workpieces into the collection box 70. In some application scenarios, the cutting device 1 drives the sliding member 60 to move along the second direction x2 on the slideway 50 through the third driving member 40 and drives the cutting assembly 30 to move to the first position. At the first position, the first driving member 10 drives the rotary cutting member 32 to approach the loading platform 20 along the first direction x1, and the second driving member 33 drives the rotary cutting member 32 to rotate to cut the workpiece to be processed 2 and cut out the cut workpieces. Further, the rotary cutting member 32 captures the cut workpieces, the first driving member 10 drives the rotary cutting member 32 to move away from the loading platform 20 along the reverse direction of the first direction x1, and the third driving member 40 drives the sliding member 60 to drive the rotary cutting member 32 to reach the second position. At the second position, the rotary cutting member 32 releases the cut workpieces to move the cut workpieces into the collection box 70, thereby automatically completing the cutting of the workpiece to be processed 2 and the transfer of the cut workpieces. Specifically, the first direction x1 may be the direction of gravity, so that the cut workpieces naturally fall into the collection box 70 under the action of gravity at the second position, saving costs. In some embodiments, the rotary cutting member 32 is provided with an air cavity 36 and an air inlet 37. The opening of the air cavity 36 faces the loading platform 20, the air inlet 37 communicates with the air cavity 36, and the air inlet 37 is used to communicate with an air pipe 80. The rotary cutting port controls the air pressure in the air cavity 36 through the air pipe 80, so as to capture and release the cut workpieces. Exemplarily, at the first position, the air pressure in the air cavity 36 can be controlled to be negative pressure to adsorb the cut workpieces, and at the second position, the air pressure in the air cavity 36 can be controlled to be positive pressure to release the cut workpieces.Thus, at the first position, the rotary cutting member 32 cuts the workpiece 2 to be processed and can capture the cut workpiece. The third driving member 40 further drives the rotary cutting member 32 to be disposed opposite to the collection box 70 at the second position, so that the rotary cutting member 32 transfers the cut workpiece to the collection box 70, thereby facilitating the collection and storage of the cut workpiece through the collection box 70, and improving the automation degree and collection efficiency of the cutting device 1.

[0054] To solve the above problems, the present application provides a cutting system, which includes a workpiece 2 to be processed and a cutting device 1. It can be understood that the relative position between the cutting device 1 and the workpiece 2 to be processed can be adjusted so that the cutting device 1 cuts the workpiece 2 to be processed at multiple different positions, in order to detect the cut workpieces cut from multiple different positions, thereby determining whether the film layer on the battery electrode sheet is evenly coated.

[0055] In summary, the cutting device 1 provided by the present application includes a first driving member 10, a carrier 20, and a cutting assembly 30. The carrier 20 is used to carry the workpiece 2 to be processed; the cutting assembly 30 is connected to the first driving member 10. The cutting assembly 30 includes a pressing shell 31, a rotary cutting member 32, and a second driving member 33. The first driving member 10 is used to drive the pressing shell 31 to approach the carrier 20 along the first direction x1 so that the pressing shell 31 presses the workpiece 2 to be processed. The first driving member 10 is used to drive the rotary cutting member 32 to approach the carrier 20 along the first direction x1, and the second driving member 33 is used to drive the rotary cutting member 32 to rotate to cut the workpiece 2 to be processed. Thus, the first driving member 10 can be used to drive the pressing shell 31 to press the workpiece 2 to be processed, thereby fixing the workpiece 2 to be processed and improving the cutting stability. The first driving member 10 can also drive the rotary cutting member 32 to approach the carrier 20, and the second driving member 33 drives the rotary cutting member 32 to rotate, so that the rotary cutting member 32 rotates to cut the workpiece 2 to be processed, improving the automation degree of cutting the workpiece 2 to be processed, thereby improving the cutting efficiency of the rotary cutting member 32. At the same time, the pressure distribution during rotary cutting is uniform, the cut edge is smoother and neater, the cut workpieces are more consistent, and the risk of scratching the workpiece 2 to be processed and causing damage to the workpiece 2 to be processed during cutting can be alleviated. Compared with other types of cutting devices, the cutting device 1 of the present application has a higher automation degree and cutting efficiency.
