[0002] At present, with the continuous development of battery technology, the demand for vehicle batteries is increasing, and the demand for corresponding lithium batteries is also increasing day by day. How to ensure that the battery is produced without stopping is currently the most effective means to increase production capacity and improve production efficiency. In the battery production process, in order to ensure the mechanical properties and production safety of the equipment, it is necessary to clean the surface of the wide-width roller in the equipment in time. In the prior art, stainless steel blades are usually used to fit the roller surface to clean the roller. However, even the fit between the stainless steel blade with a thickness of 0.03mm and the roller surface of the wide-width roller is not ideal, and the blade edge is very easy to wear after cleaning. Each team needs to stop the machine regularly to replace the blade for subsequent cleaning. The method of replacing the blade varies from person to person, which sometimes leads to uneven fit between the installed blade and the roller surface, and it is impossible to ensure that the roller surface is effectively cleaned, resulting in the quality of the produced pole piece cannot be controlled. Furthermore, although there are technical means in the prior art to use dry ice and other substances to avoid using blades to clean the stains on the roller surface, how to accurately identify the stains and improve the processing efficiency is still a problem that needs to be solved by the current personnel in this field.

[0036] At present, with the continuous development of battery technology, the demand for vehicle batteries is increasing, and the demand for corresponding lithium batteries is also increasing day by day. How to ensure that the battery is produced without stopping is currently the most effective means to increase production capacity and improve production efficiency. In the battery production process, in order to ensure the mechanical properties and production safety of the equipment, it is necessary to clean the surface of the wide-width roller in the equipment in time. In the prior art, stainless steel blades are usually used to fit the roller surface to clean the roller. However, even the fit between the stainless steel blade with a thickness of 0.03mm and the roller surface of the wide-width roller is not ideal, and the blade edge is very easy to wear after cleaning. Each team needs to stop the machine regularly to replace the blade for subsequent cleaning. The method of replacing the blade varies from person to person, which sometimes leads to uneven fit between the installed blade and the roller surface, and it is impossible to ensure that the roller surface is effectively cleaned, resulting in the quality of the produced pole piece cannot be controlled. Furthermore, although there are technical means in the prior art to use dry ice and other substances to avoid using blades to clean the stains on the roller surface, how to accurately identify the stains and improve the processing efficiency is still a problem that needs to be solved by the current personnel in this field.

[0037] The technical solution of this embodiment is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1-Figure 8 As shown, the present embodiment provides a battery roller wiping and cleaning mechanism for wiping stains on a roller surface 101 of a roller 100, comprising a wiping device 10, the wiping device 10 being arranged above the roller 100, and the wiping device 10 comprising a dust cover 11 and a spray assembly 12, the dust cover 11 being arranged on the roller surface 101, and being capable of wiping stains on the roller surface 101, the spray assembly 12 being capable of spraying dry ice at a single point or multiple points in the dust cover 11 toward the roller surface 101 to freeze and embrittle the stains; a detection device 20 and a control system, the detection device 20 being placed parallel to the roller 100, and being used for detecting stains, the detection device 20 being communicatively connected with the control system, and the control system being capable of driving the wiping device 10 to wipe the stains at a single point or multiple points.

[0039] Specifically, in this embodiment, the spraying assembly 12 of the wiping device 10 can spray dry ice at a single point or multiple points on the roller surface 101 in the dust cover 11, so as to freeze and embrittle the stains on the roller surface 101, improve the stain treatment effect, and subsequently add the lost dry ice online to ensure the cleaning effect and avoid equipment shutdown, thereby achieving the effect of increasing production capacity and production efficiency. At the same time, spraying dry ice on the roller surface 101 in the dust cover 11 can prevent the dry ice from splashing after hitting the surface of the roller 100. Further, the dust cover 11 can also wipe and collect the stains after freezing catalysis, avoiding secondary contamination of the roller 100. Specifically, in this embodiment, the detection device 20 is used to detect the stains, and the communication connection between the control system and the detection device 20 is used, so that the control system can drive the wiping device 10 to wipe the stains at a single point or multiple points, thereby realizing accurate identification of the stains, thereby achieving a one-to-one cleaning effect, and effectively improving the cleaning efficiency.

[0040] The specific structure of the battery roller wiping and cleaning mechanism in this embodiment is described below.

[0041] Combination Figure 1-Figure 4As shown, the battery roller wiping and cleaning mechanism in this embodiment includes a wiping device 10, a detection device 20 and a control system. Optionally, the battery roller wiping and cleaning mechanism is mainly used to wipe the stains on the roller surface 101 of the roller 100, and can perform real-time cleaning without interrupting power supply and production, so as to avoid affecting the production progress. It can also accurately identify the stains at a single point or multiple points to achieve rapid cleaning to improve the cleaning efficiency and quality of the stains. Specifically, the wiping device 10 in this embodiment is arranged above the roller 100, and can not only spray dry ice at a single point or multiple points toward the roller surface 101 to freeze and embrittle the stains, but also collect the frozen and embrittled stains for unified treatment to avoid secondary contamination of the roller surface 101. Specifically, in this embodiment, the detection device 20 is placed parallel to the roller 100 for detecting stains, and the detection device 20 is connected to the control system for communication, so that the detection device 20 can transmit the detected results to the control system. Similarly, the control system and the wiping device 10 are also arranged to be in communication connection, so that the control system can drive the wiping device 10 to wipe the stains at a single point or multiple points to ensure that the stains on the roller surface 101 are effectively removed. For example, each roller 100 is provided with a battery roller wiping cleaning mechanism.

[0042] like Figure 5 As shown, in this embodiment, the wiping device 10 includes a dust cover 11 and a spray assembly 12. Optionally, the dust cover 11 is provided on the roller surface 101 to wipe and uniformly collect the stains on the roller surface 101, and the spray assembly 12 is provided on the dust cover 11 and is arranged toward the roller surface 101, and the spray assembly 12 can spray dry ice at a single point or multiple points on the roller surface 101 in the dust cover 11, so as to achieve freezing and embrittlement of the stains on the roller surface 101. Exemplarily, the dry ice can be sprayed on the roller surface 101 at a high speed under the action of the spray assembly 12, so as to generate kinetic energy transfer, so that the stains and sediments on the roller surface 101 can be quickly frozen. At the same time, because the dry ice particles are at a relatively low temperature, such as at about -78.5°C, when the dry ice contacts the surface of the roller surface 101, the stains can be quickly frozen and embrittled, and a cracking effect is generated, which affects the bonding force between the stains and the roller surface 101, so that the stains are easier to be peeled off. Exemplarily, the present embodiment uses dry ice to wipe stains mainly by applying the micro-explosion effect, that is, when the dry ice particles hit the roller surface 101, they may penetrate into the gaps of the stains and quickly sublimate in a very short time, immediately expanding by about 800 times, forming a relatively strong air wave, and then blowing the stains away. The principle is mainly because dry ice is solid carbon dioxide, which is rapidly converted into gaseous carbon dioxide at normal temperature and pressure. This process is also accompanied by a rapid expansion of its volume to ensure that the stains on the roller surface 101 are blown away.

[0043] like Figure 6As shown, in this embodiment, a receiving groove 111 and a wool felt 112 are provided on the dust cover 11, and an injection port 121 and a driving structure are provided on the injection assembly 12. Optionally, the dust cover 11 is set as a trapezoidal structure, and a receiving groove 111 is provided inside it, and the notch of the receiving groove 111 is set on the side of the dust cover 11. Furthermore, the notch of the receiving groove 111 is arranged close to the roller surface 101, so that the roller surface 101 can be wiped, and the stains after freezing catalysis are collected in the receiving groove 111, which is convenient for subsequent unified treatment and can avoid the secondary pollution of the roller surface 101 by the stains after freezing catalysis. Specifically, the notch of the receiving groove 111 is equipped with a wool felt 112, and the wool felt 112 is arranged close to the roller surface 101 to wipe the stains and ensure that the dust cover 11 will not scratch the roller surface 101 during the wiping process. Optionally, in this embodiment, wool felt 112 is installed on the lower side and left and right sides of the accommodating groove 111 to ensure close contact with the roller surface 101. For example, in other embodiments, the wool felt 112 can also be replaced with other materials that are easy to wipe and will not scratch the roller surface 101, which will not be repeated here.

[0044] Combination Figure 6 and Figure 2 As shown, the spray assembly 12 is arranged on the side of the dust cover 11 away from the roller 100. Furthermore, a long hole is provided through the bottom of the receiving groove 111 in the dust cover 11. After the spray assembly 12 and the dust cover 11 are stably connected, a plurality of spray ports 121 are connected to the long hole, so that dry ice can be sprayed from the bottom of the receiving groove 111 onto the roller surface 101 at the notch of the receiving groove 111 to achieve frozen embrittlement of the stains, thereby effectively preventing the dry ice from hitting the roller 100 after being sprayed out and causing splashing, etc. through the dust cover 11. Specifically, the spray assembly 12 is provided with a manifold valve block, and a plurality of spray ports 121 are provided through the side of the manifold valve block, and each spray port 121 is arranged toward the roller surface 101 for spraying dry ice. Exemplarily, the centers of the several jets 121 are all on the same straight line to ensure that each jet 121 can spray dry ice on the roller surface 101 in the same direction. At the same time, the outlet pressure of each jet 121 in this embodiment is the same, so as to avoid changes in the force of dry ice spraying. Further, the number and spacing of the jets 121 can be set accordingly according to the size of the roller surface 101 to ensure the subsequent accurate removal of stains. Specifically, in this embodiment, the distance range of the jet 121 spraying dry ice is 5cm-15cm. Further, in this embodiment, the shape of the dry ice sprayed by the jet 121 is fan-shaped, and the fan-shaped dry ice sprayed by each two adjacent jets 121 may overlap. Accordingly, the overlapping range is 0cm-4cm, thereby ensuring that the dry ice sprayed by the jet 121 can cover the surface of the stain, so that the identified stains can be combined with the dry ice, thereby improving the cleaning quality and efficiency of the stains. In other embodiments, the corresponding numerical range can also be set as needed.

[0045] Optionally, in the present embodiment, the driving structure is also provided with several groups, and the driving structure is provided in a one-to-one correspondence with the number and position of the injection port 121. Specifically, each group of the driving structure includes a single-point motor 124, a single-point valve block 123 and a sealing ring 122. Optionally, each single-point motor 124 is communicatively connected to the control system, and each injection port 121 is connected to a single-point valve block 123, and the single-point motor 124 can control the opening and closing angle of the corresponding single-point valve block 123 to control the on and off of the dry ice spray and the amount of dry ice sprayed. Specifically, in the present embodiment, the sealing ring 122 is sleeved on the outside of the single-point valve block 123, and the single-point valve block 123 is connected to the injection port 121, and the single-point motor 124 is connected to the single-point valve block 123 to drive the single-point valve block 123 to open or close, thereby opening and closing the pipeline of its dry ice spray. Furthermore, each single-point motor 124 is connected to the control system for communication, so that the control system can start or shut down the single-point motor 124 corresponding to the stain. Exemplarily, the distance between two adjacent single-point valve blocks 123 is set to 6 cm-10 cm, so that the spray distance and the fan-shaped coverage area can be adjusted in combination with the spray effect of the spray port 121, so as to better adapt to the distance between the roller surface 101 and the wiping device 10, and ensure that the identified stains can be treated in combination with dry ice.

[0046] Specifically, in this embodiment, the lower half of the sealing ring 122 and the single-point valve block 123 are embedded in the assembly valve block, and the upper half of the single-point valve block 123 is connected to the single-point motor 124, and both are located outside the assembly valve block. Optionally, a positioning groove is provided on the single-point valve block 123, and a positioning protrusion is provided on the inner side of the sealing ring 122, and the positioning protrusion is engaged with the positioning groove, so that the sealing ring 122 and the single-point valve block 123 will not move relative to each other, and then when the single-point motor 124 drives the single-point valve block 123 to work, the sealing ring 122 will not interfere with the single-point valve block 123. Further, in this embodiment, the single-point motor 124 can control the opening and closing angle of the corresponding single-point valve block 123, so as to control the spraying amount of dry ice, and then can provide different wiping strengths for different levels of stains, save energy, improve the cleaning effect, and ensure that each stain on the roller surface 101 can be completely removed. For example, in this embodiment, the control system can control one or more single-point motors 124 to operate simultaneously, mainly depending on the location and range of the stains, so as to improve the cleaning efficiency and quality. For example, in this embodiment, the single-point motor 124 is set as a servo motor, and the opening and closing degree of the single-point valve block 123 is quantitatively controlled by the rotation angle of the servo motor.

[0047] like Figure 7 and Figure 8As shown, in this embodiment, the detection device 20 includes a CCD (Charge-coupled Device) camera 21 and a fixed component 22, and the fixed component 22 includes a fixed rod 221 and a fixed block 222. In this embodiment, the fixed component 22 is used to fix the CCD camera 21, and the CCD camera 21 is diagonally arranged with the injection component 12 to detect the area and position of the scanned stain. Optionally, the fixed block 222 can be slidably arranged on the fixed rod 221, and the CCD camera 21 is fixed on the fixed block 222, so that the position of the CCD camera 21 can be adjusted by sliding the fixed block 222 on the fixed rod 221 to ensure that the range of its detection and scanning can cover the roller surface 101. Exemplarily, in this embodiment, the CCD camera and the control system are connected by communication, so that after the CCD camera 21 detects the stain and collects the corresponding data, it is transmitted to the control system, and the control system opens the driving mechanism corresponding to the stain according to the corresponding data to eject the dry ice from the injection port 121 corresponding to the stain to achieve cleaning.

[0048] Exemplarily, in this embodiment, two CCD cameras 21 are provided, and the two CCD cameras 21 are arranged at intervals on the fixed component 22. Both CCD cameras 21 are arranged diagonally with the injection component 12, and their angles can also be adjusted according to the on-site use conditions. Optionally, in this embodiment, the CCD camera 21 adopts linear recognition, that is, two-dimensional recognition. In other embodiments, a 3D camera can also be used for three-dimensional recognition according to actual use. Specifically, in this embodiment, the detection range of each CCD camera 21 is 0mm-750mm. When it is used specifically, it is necessary to manually adjust the position and detection area setting of each CCD camera 21 when it is used for the first time, so that the detection areas of the two CCD cameras 21 can cover the bottom edge of the roller surface 101. Further, in this embodiment, the two CCD cameras 21 are respectively set as a main camera and a sub-camera. When the detection edges of the main camera and the sub-camera overlap, the detection of the main camera is dominant, that is, the detection edge on the final roller surface 101 is a combination of the detection edge of the main camera and the detection edge of the sub-camera except the overlapping area. Exemplarily, the detection accuracy of the CCD camera 21 in this embodiment is 0.002 mm.

[0049] For example, the control system in this embodiment adopts a PLC system. Furthermore, in this embodiment, the battery roller wiping and cleaning mechanism is also provided with a container for placing dry ice, and the operator can replenish the dry ice in real time through the container to avoid downtime and improve the working efficiency. The position of the container can be set as needed, which will not be described here.

[0050] The wiping method of the battery roller wiping cleaning mechanism in this embodiment is described in detail below.

[0051] like Fig. 9As shown, the wiping method of the battery roller wiping cleaning mechanism comprises the following steps:

[0052] When the wiping device 10 wipes the stains on the roller surface 101, the spraying assembly 12 sprays dry ice at a single point or multiple points in the dust removal cover 11 toward the roller surface 101 to freeze and embrittle the stains;

[0053] The dust removal hood 11 collects the frozen and embrittled dirt.

[0054] Specifically, after the battery roller wiping and cleaning mechanism is turned on, when the detection device 20 detects that there is a stain on the roller surface 101, the control system controls the wiping device 10 to wipe the stain on the roller surface 101. In addition, when the detection device 20 detects that there is a stain on the roller surface 101, the jet port 121 in the jet assembly 12 corresponding to the stain sprays dry ice. Exemplarily, in this embodiment, after the battery roller wiping and cleaning mechanism is turned on, the detection device 20 can be automatically turned on synchronously, the CCD camera 21 detects the stain on the roller surface 101 of the roller 100 by itself, and transmits the area and position of the stain to the control system, and the control system can control the single-point motor 124 corresponding to the position of the stain to start at a fixed time according to the data transmitted by the CCD camera 21 to wipe the stain at a single point or multiple points, and the control system can also control the opening and closing angle of the corresponding single-point valve block 123 to control the amount of dry ice spray, and then use different wiping levels for stains of different levels.

[0055] Furthermore, in this embodiment, the running speed of the roller 100 matches the detection time of the detection device 20, and the corresponding real-time running speed of the roller 100 is transmitted to the control system, so that the subsequent dry ice injection amount and injection time can be set at a fixed point and time. Exemplarily, in this embodiment, after the CCD camera 21 detects the stain on the roller surface 101 through a 16K high-definition camera, it can send the area and position information of the stain to the control system, and the control system calculates the time when the stain reaches the injection port 121 in combination with the rotation speed of the roller 100, thereby sending the injection time and injection amount to the single-point motor 124 corresponding to the stain, so that the single-point motor 124 starts and controls the opening and closing angle of the single-point valve block 123, realizing timed, quantitative, and positioned dry ice injection, thereby achieving efficient and high-quality stain removal.

[0056] like Fig.10 As shown, illustratively, the corresponding workflow is:

[0057] The first step is equipment operation;

[0058] In the second step, the CCD camera 21 performs scanning;

[0059] In the third step, the device determines whether there is a stain. If so, it proceeds to the next step. If not, it returns to the second step.

[0060] The fourth step is to transmit the data of the stain location and size to the control system;

[0061] Step 5: The control system turns on the corresponding single-point motor 124 after calculating the data;

[0062] Step 6: Complete the cleaning of the roller surface 101.

[0063] Therefore, any wide-width roller can be cleaned through the above-mentioned wiping method and specific process flow, and the lost dry ice can be added online, so as to ensure efficient cleaning of the equipment without stopping for a long time under the double closed-loop setting.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
