Description

Cup dust removal mechanism and battery production line

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 16, 2023, with application number 2023115333247 and invention name “Cup dust removal mechanism and battery production line”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of battery manufacturing technology, and in particular to a cup dust removal mechanism and a battery production line. Background Art

[0003] As new energy technologies mature, lithium batteries have been widely used in various fields due to their light weight, high energy storage, high power, pollution-free operation, long life, low self-discharge coefficient, and wide temperature range. During the lithium battery manufacturing process, a tray is an indispensable tool for transporting battery cells. The tray protects the semi-finished battery cell (also known as the bare cell structure) during transportation, ensuring the manufacturing quality of the lithium battery.

[0004] Normally, the tray needs to be recycled. After a batch of bare cell structures are transported to their place and the bare cell structures are taken out of the tray, the empty tray flows along the conveyor line back to the front process to circulate and transport the next batch of bare cell structures. However, after the tray has transported a batch of bare cell structures, dust and / or foreign matter will remain in the tray. When the tray is recycled to transport the next batch of bare cell structures, the remaining dust and / or foreign matter will contaminate this batch of bare cell structures, causing the dust and / or foreign matter to be brought into the battery when the bare cell structures are assembled into batteries, which in turn causes the risk of short circuit in the battery, affecting the product quality of the battery.

[0005] Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a cup dust removal mechanism and a battery production line, including but not limited to removing dust and / or foreign matter remaining in the cup during recycling, reducing the probability of contaminating the bare cell structure, and improving the product quality of the battery.

[0007] The technical solution adopted in the embodiment of this application is:

[0008] According to a first aspect of the present application, a cup dust removal mechanism is provided, comprising:

[0009] Conveyor line, used for conveying trays;

[0010] The box body has a receiving cavity, and the conveying line passes through the box body;

[0011] The blowing device is installed on the box body, and the blowing device is provided with a blowing nozzle, and the blowing nozzle is connected to the accommodating cavity;

[0012] An air extraction device is installed on the box body, and the air extraction device is provided with an air extraction end, and the air extraction end is connected to the accommodating cavity;

[0013] A transfer device is installed on the box body. The transfer device is provided with a transfer track. The transfer track is located in the accommodating cavity. The transfer track has an entrance section, an exit section and a working section located between the entrance section and the exit section. The entrance of the entrance section and the exit of the exit section are respectively connected to the conveying line. In the vertical direction, at least part of the projection of the working section does not overlap with the projection of the conveying line, and the blowing nozzle is located directly above the working section, and the exhaust port of the exhaust end is located below the working section.

[0014] The cup dust removal mechanism provided by the embodiment of the present application can move the cup out of the conveyor line through the transfer device, and then use the blowing device to blow away the dust and / or foreign matter remaining on the cup, so that the dust and / or foreign matter on the cup can be easily separated from the inner and outer walls of the cup, and the dust and / or foreign matter are extracted by the exhaust device, thereby achieving the purpose of all-round dust removal and cleaning of the cup. In addition, because the transfer device moves the cup out of the conveyor line, the probability of the dust and / or foreign matter on the cup falling on the conveyor line after being blown away is reduced, which also reduces the possibility of the dust and / or foreign matter contaminating the cup again, thereby improving the cleaning effect of the cup dust removal.

[0015] In some embodiments of the present application, the projection of the working section does not overlap at all with the projection of the conveyor line. The cup is purged by the pressurized airflow blown by the blowing nozzle, so that the dust and / or foreign matter blown off the cup is vertically avoided from the conveyor line, effectively reducing the dust and / or foreign matter blown off the cup from landing on the conveyor line.

[0016] In some embodiments of the present application, a through hole is provided at the bottom of the support cup, and the air extraction port at the air extraction end is located directly below the working section. Dust and / or foreign matter attached to the inner wall of the support cup is blown away. Since the through hole is provided at the bottom of the support cup, and the air extraction port at the air extraction end is simultaneously exhausted during the blowing, the dust and / or foreign matter are directly sucked away from the through hole after being blown away, and will not be lifted or scattered, thereby reducing the probability of the dust and / or foreign matter blown away falling onto the conveyor line.

[0017] In some embodiments of the present application, the transfer device includes a driver, a drive disc, and a connecting plate. The driver is mounted on a housing, the driver is connected to the drive disc, at least a portion of the drive disc is located within the receiving cavity and above the conveyor line, and the connecting plate is mounted on the housing. The connecting plate has an arcuate edge that matches the edge of the drive disc, and the edge of the drive disc and the arcuate edge are opposite to form a transfer track. The driver drives the drive disc to move, and then the drive disc drives the cup to move forward along the transfer track, so that the cup quickly passes through the working section, thereby improving the efficiency of dust removal and cleaning of the cup.

[0018] In some embodiments of the present application, the driving disc is entirely located in the accommodating cavity. In this case, the housing completely covers the driving disc, which can simplify the structural design of the housing.

[0019] In some embodiments of the present application, a friction member is installed on the circumferential edge of the driving disc to increase the relative friction coefficient between the edge of the driving disc and the outer wall of the support cup, thereby reducing or even eliminating the slipping frequency.

[0020] In some embodiments of the present application, the friction member is an annular elastic sleeve, which is wrapped around the circumferential edge of the driving disc; or, the friction member includes a plurality of friction blocks, each of which is sequentially and adjacently fixed on the circumferential edge of the driving disc.

[0021] In some embodiments of the present application, an annular groove is provided on the circumferential outer wall of the support cup, and the annular groove is adapted to the edge and arcuate edge of the drive disc. In this way, the edge of the drive disc and the arcuate edge of the connecting plate jointly form a positioning constraint for the support cup, thereby allowing the support cup to accurately enter the transfer track.

[0022] In some embodiments of the present application, the arc length of the corresponding working section of the arc-shaped edge is greater than or equal to the circumference of the annular groove. The cup rotates at least once, thereby blowing all the walls of the inner cavity and all the outer walls of the cup, thereby removing dust and cleaning the cup as thoroughly as possible.

[0023] In some embodiments of the present application, the blowing device is provided with a plurality of blowing nozzles, which are spaced apart in sequence corresponding to the arc-shaped direction of the working section. The plurality of blowing nozzles comprehensively blows the cavity wall and outer wall of the cup to remove dust from the cup as thoroughly as possible, thereby improving the cleanliness of the cup.

[0024] In some embodiments of the present application, the air outlets of each blowing nozzle are arranged as linear outlets, and the linear outlets of two adjacent blowing nozzles are arranged so that their lengths intersect. The pressurized airflows blown out by each blowing nozzle form a planar air curtain. Compared with columnar or linear pressurized airflows, the planar air curtain can blow dust off the cups over a wider range, making the dust removal and cleaning of the cups more efficient and clean.

[0025] In some embodiments of the present application, along the conveying direction of the cup in the working section, the linear air outlets of each blowing nozzle intersect at different angles with the extension direction of the conveying line. The planar air curtain formed by the blowing nozzles can fully sweep the cavity and outer walls of the cup, thereby removing dust from the cup as thoroughly as possible and improving the cleanliness of the cup.

[0026] In some embodiments of the present application, the exhaust end is configured to be trumpet-shaped, thereby reducing the assembly space occupied by the exhaust end in the support cup dust removal mechanism, which is conducive to the miniaturization and compact design of the support cup dust removal mechanism.

[0027] In some embodiments of the present application, the air extraction capacity of the air extraction device is greater than or equal to the air blowing capacity of the air blowing device. This ensures that the receiving cavity of the box is always in a relatively negative pressure state or a relatively stable pressure state, so that the dust and / or foreign matter blown off the cup are sucked away as soon as they are released, and the dust and / or foreign matter will not be spread and raised.

[0028] In some embodiments of the present application, the cup dust removal mechanism further includes a negative pressure wind speed detection sensor, which is installed in the receiving cavity and is used to detect the negative pressure wind speed in the receiving cavity. The cup dust removal mechanism uses the negative pressure wind speed detection sensor to automatically detect the negative pressure wind speed in the receiving cavity of the box, thereby achieving negative pressure wind speed monitoring.

[0029] In some embodiments of the present application, the cup dust removal mechanism further includes an ion wind generator, which is mounted on the housing. The ion wind generator has an air outlet connected to the receiving cavity, and the air outlet of the ion wind generator is arranged above the inlet section. The ionic charge of the ion wind neutralizes the static charge of the dust and / or foreign matter, thereby eliminating the electrostatic adsorption capacity of the dust and / or foreign matter, so that the dust and / or foreign matter attached to the cup can be blown away from the cup as thoroughly as possible, thereby improving the cleanliness of the cup dust removal.

[0030] According to another aspect of the present application, a battery production line is provided. The battery production line includes a cup dust removal mechanism as described above. The cup dust removal mechanism provided by the embodiment of the present application is used in the battery production line to remove dust from the cup used to carry and transport the bare cell structure. During the dust removal and cleaning process, the transfer device can move the cup out of the conveyor line, and then the dust and / or foreign matter remaining on the cup is blown away by the blowing device, and the dust and / or foreign matter are extracted by the exhaust device, thereby achieving the purpose of all-round dust removal and cleaning of the cup.

[0040] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit this application.

They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0042] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0043] Currently, market developments indicate that the application of power batteries, particularly lithium batteries, is becoming increasingly widespread. Lithium batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in police equipment, military equipment, and aerospace. As the application of lithium batteries continues to expand, market demand is also growing.

[0044] The preparation of lithium batteries requires a series of steps, which, in order of production, include but are not limited to a compounding step, a winding step, a shaping step, a battery cell assembly step, and a welding step. After the winding step is completed, the semi-finished bare cell structure is formed. During the transportation of the bare cell structure to subsequent steps, a support cup must be used to carry the bare cell structure, thereby protecting it and reducing the probability of damage from external forces or collisions during transportation, thereby improving the yield of lithium batteries.

[0045] The composite process refers to the roll-combination of the positive electrode sheet, separator and negative electrode sheet into a cell material roll for winding the bare cell structure.

[0046] The winding process refers to winding the composite formed battery cell material roll to form a bare battery cell structure semi-finished product. At this time, the bare battery cell structure semi-finished product formed by winding is in a fluffy state, the shape outline of the bare battery cell structure is not fixed, and the positive and negative electrodes in the bare battery cell structure are easy to slip and difficult to assemble.

[0047] The shaping process refers to the use of hot pressing or cold pressing to clamp and press the fluffy bare cell structure semi-finished product to fix the shape contour of the bare cell structure, thereby solving the problem that the positive and negative electrodes in the fluffy bare cell structure are easy to slip and difficult to assemble, which is conducive to improving the assembly accuracy and efficiency of the subsequent battery cell assembly process.

[0048] The process of assembling battery cells refers to assembling the shaped bare cell structure, current collector, shell, shell cover and other components into battery cells.

[0049] The welding process refers to welding components such as the shell, shell cover and electrode terminals so that the shell and shell cover are sealed and the electrode terminals are electrically connected to the bare battery cell structure.

[0050] In the related art, the tray is recycled to transport batches of bare cell structures between adjacent processes. However, after the tray has transported a batch of battery cells, dust and / or foreign matter will remain in the tray. If the dust and / or foreign matter remaining in the tray is not cleaned up in time, when the tray transports the next batch of bare cell structures, the dust and / or foreign matter remaining in the tray will contaminate the bare cell structure. Then, when these contaminated bare cell structures are used to assemble to form battery cells, the contaminated bare cell structures will bring dust and / or foreign matter into the battery cells, resulting in a short circuit risk in the battery cells. When these battery cells are assembled to form lithium batteries, these battery cells with a short circuit risk will affect the product quality of the lithium battery.

[0051] Based on the above considerations, in order to solve the problem in the related art that dust and / or foreign matter will remain in the support cup when the support cup is circulated to transport the bare cell structure, causing the bare cell structure to be contaminated, and then affecting the product quality of the lithium battery, the embodiment of the present application designs a support cup dust removal mechanism. The support cup dust removal mechanism provided by the embodiment of the present application can move the support cup out of the conveyor line through a transfer device, and then, through a blowing device, blow away the dust and / or foreign matter remaining on the support cup, so that the dust and / or foreign matter on the support cup can be easily separated from the inner wall and outer wall of the support cup, and the dust and / or foreign matter are extracted by an exhaust device, thereby achieving the purpose of all-round dust removal and cleaning of the support cup. In addition, since the transfer device moves the support cup out of the conveyor line, the probability of the dust and / or foreign matter on the support cup falling on the conveyor line after being blown away is reduced, which also reduces the possibility of dust and / or foreign matter contaminating the support cup again, thereby improving the cleaning effect of dust removal and cleaning of the support cup.

[0052] Furthermore, the embodiment of the present application also designs a battery production line that uses the cup dust removal mechanism to remove dust and clean the cup, which is used to manufacture lithium batteries and improve the product quality of lithium batteries.

[0053] The cup dust removal mechanism and battery production line designed in the embodiment of the present application are applied to the manufacture and production of lithium batteries, especially the manufacture and production of cylindrical lithium batteries. The cup after dust removal and cleaning is used to transport the bare cell structure and assemble the bare cell structure into a lithium battery. The prepared lithium battery can be used for but not limited to mobile phones, tablets, laptops, electric toys, power tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles and spacecraft, etc.

[0054] In addition, the cup dust removal mechanism designed in the embodiments of the present application is used to remove dust from the transport carrier (i.e., the cup). The cleaned cup can also be used to transport PCB motherboards in PCB manufacturing; the cleaned cup can also be used to transport chips, silicon wafers, etc. in chip manufacturing; or the cleaned cup can be used to transport parts that need to be transported in other industrial product manufacturing.

[0055] In the following, the embodiments of the present application are described by taking an example in which a tray is used to transport a bare cell structure during the manufacturing process of a lithium battery.

[0056] According to some embodiments of the present application, as shown in Figures 1 to 3, the cup dust removal mechanism includes a conveyor line 20, a box body 30, a transfer device 40, a blowing device 50 and an exhaust device 60. The conveyor line 20 is used to convey the cup 10, so that the cup 10 can be circulated and transported between two preset adjacent workstations. The box body 30 has a accommodating cavity 31, and the conveyor line 20 passes through the box body 30, that is, the cup 10 transported by the conveyor line 20 will also enter the accommodating cavity 31 along with the conveyor line 20. The transfer device 40 is installed on the box body 30, and the transfer device 40 is used to transfer the cup 10 entering the accommodating cavity 31, so that the cup 10 entering the accommodating cavity 31 is offset relative to the conveyor line 20, so that the cup 10 can be conveniently and as thoroughly as possible for dust removal and cleaning. The transfer device 40 is provided with a transfer track 410, which is located in the accommodating cavity 31. The transfer track 410 has an entrance section 411, an exit section 412, and a working section 413 located between the entrance section 411 and the exit section 412. The entrance of the entrance section 411 and the exit of the exit section 412 are respectively docked with the conveyor line 20, that is, the entrance of the entrance section 411 docks with the conveyor line 20 at the box entrance 32, and the exit of the exit section 412 docks with the conveyor line 20 at the box exit 33. In this way, the cup 10 transported into the accommodating cavity 31 by the conveyor line 20 enters the entrance section 411 of the transfer track 410 at the box entrance 32, and moves along the transfer track 410 to the working section 413, then the cup 10 moves to the exit section 412, and the cup 10 returns to the conveyor line 20 from the exit of the exit section 412 at the box exit 33. In the cup dust removal mechanism of the embodiment of the present application, in the vertical direction, at least part of the projection of the working section 413 does not overlap with the projection of the conveyor line 20, that is, in the accommodating cavity 31 of the box body 30, the cup 10 that moves along the transfer track 410 to the working section 413 is in a relatively offset state relative to the section of the conveyor line 20 located in the accommodating cavity 31, that is, the cup 10 is offset from the conveyor line 20 in the working section 413. The blowing device 50 is installed on the box body 30, and the blowing device 50 is provided with a blowing nozzle 51, and the blowing nozzle 51 is connected to the accommodating cavity 31. The blowing device 50 blows a predetermined pressure of air into the accommodating cavity 31 through the blowing nozzle 51, and the blowing nozzle 51 is located directly above the working section 413. In this way, the pressurized airflow entering the accommodating cavity 31 sweeps the cup 10, so that the dust and / or foreign matter attached to the inner and outer walls of the cup 10 are blown away. Then, the dust and / or foreign matter separated from the cup 10 is extracted by the exhaust device 60 , that is, the exhaust device 60 is installed on the box body 30 , and the exhaust device 60 is provided with an exhaust end 61 , which is connected to the accommodating cavity 31 .Furthermore, the air extraction port 62 of the air extraction end 61 is located below the working section 413. Correspondingly, since the air blowing nozzle 51 of the air blowing device 50 is located directly above the working section 413, the dust and / or foreign matter blown off from the support cup 10 can be directly sucked downward by the air extraction device 60, thereby removing dust and cleaning the support cup 10. Moreover, since the support cup 10 is offset from the conveyor line 20 in the working section 413, the probability of dust and / or foreign matter detached from the support cup 10 falling on the conveyor line 20 after being blown off can be reduced during the process of the air blowing nozzle 51 blowing the support cup 10, thereby reducing the probability of the support cup 10 being re-contaminated by dust and / or foreign matter falling on the conveyor line 20 when it returns to the conveyor line 20 at the outlet of the outlet section 412, thereby improving the cleanliness of the bare cell structure of the support cup 10, which is beneficial to improving the product quality of the lithium battery produced.

[0057] "The entrance of the entrance section 411 is docked with the conveyor line 20" means that when the tray 10 is transported to the box entrance 32 by the conveyor line 20, the tray 10 can enter the entrance section 411 from the conveyor line 20. In terms of the assembly structure, the entrance of the entrance section 411 can be connected to the conveyor line 20, so that the tray 10 is directly transferred from the conveyor line 20 to the entrance section 411; or, the entrance of the entrance section 411 can be not directly connected to the conveyor line 20. In this case, the entrance of the entrance section 411 is set above the conveyor line 20, and the height of the entrance of the entrance section 411 relative to the conveyor line 20 is less than the height of the tray 10 located on the conveyor line 20, so that the tray 10 can smoothly enter the entrance section 411.

[0058] "The outlet of the outlet section 412 is docked with the conveyor line 20" means that when the tray 10 moves along the transfer track 410 to the outlet of the outlet section 412, that is, at the box outlet 33, the tray 10 can return from the outlet section 412 to the conveyor line 20. In terms of the assembly structure, the outlet of the outlet section 412 can be connected to the conveyor line 20, so that the tray 10 is directly transferred from the outlet section 412 back to the conveyor line 20; or, the outlet of the outlet section 412 can be not directly connected to the conveyor line 20. In this case, the outlet of the outlet section 412 is set above the conveyor line 20, and the height of the outlet of the outlet section 412 relative to the conveyor line 20 is less than the height of the tray 10 located on the conveyor line 20, so that the tray 10 can smoothly return from the outlet section 412 to the conveyor line 20.

[0059] “At least part of the projection of the working section 413 does not overlap with the projection of the conveyor line 20” means that, in the vertical direction, when looking down at the transfer track 410 and the conveyor line 20, the vertical projection of the working section 413 may be such that only a part of the working section 413 overlaps with the vertical projection of the conveyor line 20, while the other part of the working section 413 is staggered from the conveyor line 20 (i.e., only a part of the working section 413 blocks the conveyor line 20), or the working section 413 may be completely staggered from the conveyor line 20 (i.e., the working section 413 does not block the conveyor line 20 at all). Therefore, when the tray 10 moving on the working section 413 moves to the part of the working section 413 that is staggered from the conveyor line 20, the vertical projection of the tray 10 is staggered from the vertical projection of the conveyor line 20.

[0060] “The exhaust port 62 of the exhaust end 61 is located below the working section 413” means that in the vertical direction, in the working section 413, the exhaust port 62 of the exhaust end 61 is arranged directly below the part of the working section 413 whose projection is staggered with the projection of the conveyor line 20, so that the dust and / or foreign matter blown off from the cup 10 can avoid the conveyor line 20 and be sucked away, thereby effectively reducing the dust and / or foreign matter blown off from the cup 10 and falling on the conveyor line 20.

[0061] In some embodiments of the present application, only a portion of the working section 413 blocks the conveyor line 20, which means that the projection of a small section of the working section 413 toward and adjacent to the entrance section 411 and the projection of a small section of the working section 413 toward and adjacent to the exit section 412 overlap with the projection of the conveyor line 20, and the remaining portion of the working section 413 is staggered from the conveyor line 20, and the blowing nozzle 51 is located directly above the portion of the working section 413 that is staggered from the conveyor line 20. In other words, when the cup 10 gradually moves from the entrance section 411 to the working section 413 along the transfer track 410, the portion of the vertical projection of the cup 10 that overlaps with the conveyor line 20 gradually decreases until there is no overlap at all. Then, when the cup 10 gradually moves into the exit section 412, the portion of the vertical projection of the cup 10 that overlaps with the conveyor line 20 gradually increases until the cup 10 returns to the conveyor line 20. When the cup 10 moves to the portion of the working section 413 that is offset from the conveyor line 20, the pressurized air flow blown out by the blowing nozzle 51 purges the cup 10, so that the dust and / or foreign matter blown off the cup 10 avoids the conveyor line 20 in the vertical direction, effectively reducing the dust and / or foreign matter blown off the cup 10 from falling on the conveyor line 20. Since the exhaust port 62 of the exhaust end 61 is located below the working section 413, the dust and / or foreign matter blown off the cup 10 can avoid the conveyor line 20 and be sucked away, thereby cleaning the dust and / or foreign matter.

[0062] In some embodiments of the present application, the projection of the working section 413 does not overlap with the projection of the conveyor line 20 at all, that is, when looking down at the transfer track 410 and the conveyor line 20, the entire working section 413 and the conveyor line 20 are completely staggered with each other. At this time, the entire working section 413 can be used to set the blowing nozzle 51 directly above, and the entire working section 413 can be used to set the air extraction port 62 directly below. In fact, as shown in Figure 3, a plurality of blowing nozzles 51 are sequentially spaced apart along the arc-shaped direction of the working section 413 directly above the entire working section 413, and, in combination with Figures 3 and 5, the entire working section 413 is located directly below the range of the air extraction port 62 (i.e., the air extraction port 62 of the air extraction end 61 is located directly below the working section 413). When the cup 10 moves to the working section 413, it is immediately swept by the pressurized air flow blown by the air nozzle 51, so that the dust and / or foreign matter blown off the cup 10 are vertically avoided by the conveyor line 20, effectively reducing the dust and / or foreign matter blown off the cup 10 from falling on the conveyor line 20. Because the entire working section 413 is located directly below the exhaust port 62, the dust and / or foreign matter blown off the cup 10 can avoid the conveyor line 20 and be sucked away, thereby cleaning the dust and / or foreign matter.

[0063] The arrangement of the cup dust removal mechanism of the embodiment of the present application is as follows: the entire working section 413 and the conveyor line 20 are completely staggered with each other, and a plurality of blowing nozzles 51 are arranged in sequence along the arc-shaped direction of the working section 413 directly above the entire working section 413, and the entire working section 413 is located directly below the range of the exhaust port 62.

[0064] As shown in Figures 3 and 7, a through hole 11 is provided at the bottom of the support cup 10. As shown in Figures 1-3 and 7, the support cup 10 is provided with a placement cavity 13, and the bare cell structure is placed in the placement cavity 13. The bare cell structure is carried by the support cup 10 and transported along the conveyor line 20 between two adjacent workstations. Generally, the dust and / or foreign matter attached to the cavity wall of the placement cavity 13 of the support cup 10 is more than the dust and / or foreign matter attached to the outer wall of the support cup 10. However, whether it is the dust and / or foreign matter attached to the cavity wall of the placement cavity 13 or the dust and / or foreign matter attached to the outer wall of the support cup 10, if dust removal and cleaning are not performed, the bare cell structure will be polluted during the process of recycling the support cup 10 to transport the bare cell structure. Therefore, it is essential to use the support cup dust removal mechanism provided by the embodiment design of the present application to remove dust from the support cup 10. When the cup 10 moves to the working section 413, it is immediately swept by the pressurized air flow blown by the blowing nozzle 51, and the dust and / or foreign matter attached to the cavity wall of the placement cavity 13 is blown away. Since the bottom of the cup 10 is provided with a through hole 11, and the air suction port 62 of the air suction end 61 also extracts air synchronously, the dust and / or foreign matter attached to the cavity wall of the placement cavity 13 is directly sucked away from the through hole 11 after being blown away, and will not be lifted up or scattered from the placement cavity 13, thereby reducing the probability of the dust and / or foreign matter blown away from the cavity wall of the placement cavity 13 falling onto the conveyor line 20. In addition, the dust and / or foreign matter attached to the outer wall of the cup 10 is also blown away and then directly sucked away by the air suction port 62 of the air suction end 61, effectively reducing the dust and / or foreign matter blown away from the outer wall of the cup 10 falling onto the conveyor line 20.

[0065] In order to minimize the dust and / or foreign matter blown off from the cup 10 and falling onto the conveyor line 20, in some embodiments of the present application, the air extraction volume of the exhaust device 60 is greater than or equal to the air blowing volume of the blowing device 50 per unit time. This ensures that the receiving cavity 31 of the box body 30 is always in a relatively negative pressure state or a relatively stable pressure state, and the air flow direction in the receiving cavity 31 always flows to the exhaust port 62, so that the dust and / or foreign matter blown off from the cup 10 are sucked away as soon as they are detached, and the dust and / or foreign matter will not spread and fly, nor will they fly toward the box inlet 32 ​​and the box outlet 33 and fly out of the receiving cavity 31.

[0066] "Within a unit of time" means that the time during which the exhaust device 60 blows air into the accommodating cavity 31 is equal to the time during which the exhaust device 60 draws air from the accommodating cavity 31, and during this time, the amount of air drawn by the exhaust device 60 is greater than or equal to the amount of air blown by the blowing device 50. For example, if 1 second is used as the unit of time, the amount of air drawn by the exhaust device 60 within 1 second is greater than or equal to the amount of air blown by the blowing device 50 within 1 second.

[0067] A "relatively negative pressure state" means that the air pressure within the containment cavity 31 is lower than the atmospheric pressure of the external environment. Therefore, in addition to the air blowing device 50 blowing air into the containment cavity 31 through the air blowing nozzle 51, air from the external environment simultaneously flows into the containment cavity 31 from the box inlet 32 ​​and the box outlet 33 due to the relative pressure difference, and ultimately flows to the air extraction port 62. This allows dust and / or foreign matter blown off the cup 10 to be sucked away as soon as they are detached, preventing the dust and / or foreign matter from spreading and becoming airborne, nor from flying toward the box inlet 32 ​​and the box outlet 33 and out of the containment cavity 31.

[0068] "Relatively stable pressure state" means that, relative to the atmospheric pressure of the external environment, the air pressure in the containment cavity 31 is equal to the atmospheric pressure of the external environment. At this time, the air from the external environment will neither flow into the containment cavity 31 from the box inlet 32 ​​and the box outlet 33, nor will the airflow in the containment cavity 31 flow out of the external environment from the box inlet 32 ​​and the box outlet. In the containment cavity 31, since the blowing device 50 continuously blows the airflow and the exhaust device 60 continuously sucks the airflow, the flow direction of the airflow in the containment cavity 31 is fixed, that is, the airflow in the containment cavity 31 flows from the blowing nozzle 51 to the exhaust port 62. Therefore, the dust and / or foreign matter blown off from the cup 10 are sucked away as soon as they are detached, and the dust and / or foreign matter will not spread and fly, nor will they fly toward the box inlet 32 ​​and the box outlet 33 and fly out of the containment cavity 31.

[0069] The dust removal mechanism of the embodiment of the present application is arranged in such a way that the air extraction volume of the air extraction device 60 is always greater than the air blowing volume of the air blowing device 50 within a unit time.

[0070] In some embodiments of the present application, the transfer device 40 does not need to be equipped with a power device to drive the cups 10 to move along the transfer track 410. Since the conveyor line 20 is in continuous motion, the cups 10 on the conveyor line 20 will continuously enter the transfer track 410 from the entrance of the entrance section 411. In this way, on the transfer track 410, the cups 10 at the back will push the cups 10 at the front to move forward.

[0071] In order to improve the efficiency of dust removal and cleaning of the tray cup 10, in some embodiments of the present application, as shown in Figures 3 and 4, the transfer device 40 includes a driver 41, a drive disc 42 and a connecting plate 43. The driver 41 is connected to the drive disc 42, and the drive disc 42 is driven by the driver 41 to rotate, and then the drive disc 42 drives the tray cup 10 to move forward along the transfer track 410, so that the tray cup 10 quickly passes through the working section 413, thereby improving the efficiency of dust removal and cleaning of the tray cup 10. Specifically, as shown in Figures 3 and 4, the driver 41 is installed on the box body 30, and the connecting plate 43 is installed on the box body 30. At least a portion of the drive disc 42 is located in the accommodating cavity 31 and above the conveyor line 20. The connecting plate 43 has an arc-shaped edge 45 that matches the edge of the drive disc 42. The edge of the drive disc 42 is opposite to the arc-shaped edge 45 to form the transfer track 410. Since the part of the driving disc 42 located in the accommodating cavity 31 is located above the conveyor line 20, the cup 10 moving along the conveyor line 20 will be blocked by the driving disc 42, and then the cup 10 is driven by the rotating driving disc 42 to enter between the edge of the driving disc 42 and the arc-shaped edge 45 of the connecting plate 43 (that is, the cup 10 is driven by the rotating driving disc 42 to enter the transfer track 410), until the driving disc 42 drives the cup 10 to leave the transfer track 410 from the exit of the exit section 412, and the cup 10 returns to the conveyor line 20.

[0072] In some embodiments of the present application, only the portion of the drive disc 42 that cooperates with the curved edge 45 of the connecting plate 43 to form the transfer track 410 extends into the accommodating cavity 31 of the box body 30. Thus, a corresponding opening needs to be provided on the wall of the box body 30, and the portion of the drive disc 42 that extends into the box body 30 enters the accommodating cavity 31 through the opening.

[0073] In some embodiments of the present application, as shown in Figure 1, the drive disc 42 is entirely located within the accommodating cavity 31. At this time, the box body 30 completely covers the drive disc 42, thereby reducing the number of openings on the box wall of the box body 30 and simplifying the structural design of the box body 30 of the cup dust removal mechanism.

[0074] Generally, the support cup 10 is a supporting fixture made of metal material for carrying a bare cell structure for transportation. Alternatively, the support cup 10 can also be made of other hard materials, such as hard plastic injection molding. The drive disc 42 is made of metal material, or it can also be made of other hard materials, such as hard plastic injection molding. When the edge of the hard drive disc 42 contacts the outer wall of the hard support cup 10, the two hard materials are more likely to slip. Therefore, in some embodiments of the present application, as shown in Figures 3 and 4, a friction member 44 is installed on the circumferential edge of the drive disc 42. In this way, the edge of the drive disc 42 contacts the outer wall of the support cup 10 through the friction member 44 to increase the relative friction coefficient between the edge of the drive disc 42 and the outer wall of the support cup 10, thereby reducing or even eliminating the slipping frequency.

[0075] In some embodiments of the present application, as shown in Figures 3 and 4 , the friction member 44 is an annular elastic sleeve that wraps around the circumferential edge of the drive disc 42. The annular elastic sleeve can be quickly and easily assembled onto the circumferential edge of the drive disc 42, simplifying and facilitating assembly efficiency. The annular elastic sleeve increases the relative friction coefficient between the edge of the drive disc 42 and the outer wall of the support cup 10, reducing or even eliminating slippage.

[0076] In some embodiments of the present application, the friction member 44 includes a plurality of friction blocks, each of which is sequentially and adjacently snap-fitted and fixed to the circumferential edge of the drive disc 42. When the plurality of friction blocks are snap-fitted and fixed to the circumferential edge of the drive disc 42, although two adjacent friction blocks are snap-fitted and fixed to the circumferential edge of the drive disc 42 as closely as possible, a small gap inevitably remains between the two adjacent friction blocks. The presence of these gaps helps to increase the relative friction coefficient between the edge of the drive disc 42 and the outer wall of the cup 10, thereby reducing or even eliminating the frequency of slippage.

[0077] To ensure that the cup 10 on the conveyor line 20 accurately enters the transfer track 410, in some embodiments of the present application, as shown in Figures 1 to 3 and 7, an annular groove 12 is provided on the circumferential outer wall of the cup 10. The annular groove 12 mates with the edge and curved edge 45 of the drive disc 42. Specifically, when the cup 10 on the conveyor line 20 moves to the entrance of the entrance section 411, the curved edge 45 of the connecting plate 43 first engages with the annular groove 12. Subsequently, the cup 10 is blocked by the drive disc 42, and the edge of the drive disc 42 also engages with the annular groove 12. Thus, the edge of the drive disc 42 and the curved edge 45 of the connecting plate 43 jointly form a positioning restriction for the cup 10, thereby ensuring that the cup 10 accurately enters the transfer track 410. In practice, the friction member 44 on the edge of the drive disc 42 abuts against the bottom of the annular groove 12, and the curved edge 45 of the connecting plate 43 also abuts against the bottom of the annular groove 12. As the drive disc 42 rotates to drive the cup 10 along the transfer track 410, the friction member 44 elastically deforms, causing the cup 10 to abut against the curved edge of the connecting plate 43 and rotate forward. Therefore, the gap between the edge of the drive disc 42 and the curved edge 45 of the connecting plate 43 is slightly larger than the diameter of the bottom of the annular groove 12, but smaller than the diameter of the outer wall of the cup 10. Furthermore, the thickness of the friction member 44 is greater than half the difference between the gap between the edge of the drive disc 42 and the curved edge 45 of the connecting plate 43 and the diameter of the bottom of the annular groove 12. Thus, after the drive disc 42, connecting plate 43, and friction member 44 are assembled, when the cup 10 enters the transfer track 410, the friction member 44 abuts the bottom of the annular groove 12, which in turn abuts against the curved edge 45 of the connecting plate 43. Driven by the rotation of the drive disc 42, the cup 10 rotates forward along the curved edge 45.

[0078] In some embodiments of the present application, the arc length of the corresponding working section 413 of the arc-shaped edge 45 is greater than or equal to the circumference of the annular groove 12. In other words, as the cup 10 rotates and advances on the working section 413 of the transfer track 410, the cup 10 completes at least one rotation, thereby completely cleaning the entire cavity and outer walls of the inner cavity 13 where the cup 10 is placed, thereby removing dust from the cup 10 as thoroughly as possible.

[0079] In some embodiments of the present application, the arc length of the corresponding working section 413 of the arc-shaped edge 45 is greater than the circumference of the annular groove 12, that is, the cup 10 rotates more than one circle when it rotates forward on the working section 413 of the transfer track 410, preferably 4 / 3 of a circle, so that the diameter of the drive disc 42 and the size of the arc-shaped edge 45 of the connecting plate 43 will not be too large, which is conducive to the miniaturization and compact design of the cup dust removal mechanism. In addition, as shown in Figure 6, the air outlet of each blowing nozzle 51 is set as a linear air outlet 52. In this way, the pressure air flow blown out by each blowing nozzle 51 forms a planar wind curtain. The planar wind curtain can blow and remove dust from the cup 10 in a larger range than the columnar or linear pressure air flow, so that the dust removal and cleaning work of the cup 10 is more efficient and the cleanliness of the dust removal and cleaning is also higher. Referring to FIG3 and FIG6 , the linear air outlets 52 of two adjacent blowing nozzles 51 are arranged in a direction of length (i.e., the direction indicated by the arrow S in FIG6 ) that intersects each other. In other words, the planar air curtains blown out by the two adjacent blowing nozzles 51 intersect with each other. In this way, when the cup 10 rotates and advances in the working section 413 and the cup 10 rotates 4 / 3 of a circle, the planar air curtains blown out by each blowing nozzle 51 can fully sweep the cavity wall and outer wall of the inner cavity 13 of the cup 10, thereby removing dust from the cup 10 as thoroughly as possible and improving the cleanliness of the cup 10.

[0080] In some embodiments of the present application, the planar air curtains blown out by two adjacent blowing nozzles 51 are perpendicular to each other, that is, the linear length directions of the linear air outlets 52 of the two adjacent blowing nozzles 51 are perpendicular to each other. Alternatively, in some embodiments of the present application, along the conveying direction of the cup 10 in the working section 413, the intersection angles of the linear length directions of the linear air outlets 52 of each blowing nozzle 51 and the extension direction of the conveyor line 20 (that is, the direction indicated by the X arrow shown in Figures 1 to 4) are all different. In this way, when the cup 10 rotates forward in the working section 413, and the cup 10 rotates 4 / 3 of a circle, the planar air curtains blown out by each blowing nozzle 51 can fully sweep the cavity wall and outer wall of the inner cavity 13 of the cup 10, so as to remove dust and clean the cup 10 as thoroughly as possible, thereby improving the cleanliness of the dust removal and cleaning of the cup 10.

[0081] As shown in FIG5 , in some embodiments of the present application, the air extraction end 61 is configured to be trumpet-shaped, and the air extraction port 62 is the larger end of the trumpet-shaped air extraction end 61. This reduces the assembly space occupied by the air extraction end 61 of the air extraction device 60 in the cup dust removal mechanism, which is conducive to the miniaturization and compactness of the cup dust removal mechanism.

[0082] In some embodiments of the present application, the blowing device 50 uses an air pump to actively blow air, and the exhaust device 60 also uses an air pump to actively suck air. This can ensure that the blowing volume of the blowing airflow and the suction volume of the suction airflow are always stable, reducing or even avoiding the situation where the dust removal and cleaning effect of the cup 10 in the box body 30 is not ideal due to unstable blowing airflow or unstable suction airflow.

[0083] In some embodiments of the present application, the blowing device 50 uses the pressurized airflow provided by the airflow pipeline of the factory workshop to blow air, and the exhaust device 60 also uses the airflow pipeline of the factory workshop to suck the airflow. However, the pressure of the airflow pipeline of the factory workshop fluctuates, which causes the blowing amount of the blowing airflow to be greater than the suction amount of the suction airflow, so that a relatively positive pressure state is formed in the accommodating cavity 31 of the box body 30, resulting in the failure of dust removal and cleaning of the support cup 10. In order to reduce or even avoid this situation, as shown in Figures 1, 2 and 5, the support cup dust removal mechanism also includes a negative pressure wind speed detection sensor 70, which is installed in the accommodating cavity 31 and close to the exhaust end 61. The negative pressure wind speed detection sensor 70 is used to detect the negative pressure wind speed in the accommodating cavity 31. The support cup dust removal mechanism uses the negative pressure wind speed detection sensor 70 to automatically detect the negative pressure wind speed in the accommodating cavity 31 of the box body 30, thereby realizing negative pressure wind speed monitoring. When the pressure of the air flow pipeline in the factory workshop changes unstably and causes a relatively positive pressure state in the accommodating cavity 31 of the box body 30 (that is, the wind speed in the accommodating cavity 31 detected by the negative pressure wind speed detection sensor 70 is less than the set threshold), the negative pressure wind speed detection sensor 70 will issue an alarm, and the staff will be able to maintain and adjust the cup dust removal mechanism in time, so that the cup dust removal mechanism can continue to remove dust and clean the cup 10 normally.

[0084] "Relative positive pressure state" means that, relative to the atmospheric pressure of the external environment, the air pressure in the containment cavity 31 is greater than the atmospheric pressure of the external environment. At this time, the airflow in the containment cavity 31 will flow from the box inlet 32 ​​and the box outlet 33 to the external environment under the action of the relative air pressure difference (that is, the airflow flows from the containment cavity 31 to the outside of the box body 30). In this way, the airflow will carry the dust and / or foreign matter blown off from the support cup 10 and scatter. In the containment cavity 31, the dust and / or foreign matter will fall onto the conveyor line 20; at the box inlet 32 ​​and the box outlet 33, the dust and / or foreign matter will not only fall onto the conveyor line 20 but also onto the support cups 10 located at these two places, especially the support cups 10 at the box outlet 33 that have been cleaned by dust removal will be contaminated again.

[0085] In some embodiments of the present application, the cup dust removal mechanism further includes a control module (not shown), and the blowing nozzle 51 of the blowing device 50 and the air extraction end 61 of the air extraction device 60 are both equipped with electromagnetic switch valves. The control module is electrically connected to the negative pressure wind speed detection sensor 70, the control module is electrically connected to the power equipment of the conveyor line 20, the control module is electrically connected to the electromagnetic switch valve on the blowing device 50 and the electromagnetic switch valve on the air extraction end 61, and the control module is electrically connected to the driver 41 of the transfer device 40. When the pressure of the air flow pipeline in the factory workshop changes unstably and causes a relative positive pressure state to occur in the accommodating cavity 31 of the box body 30, the negative pressure wind speed detection sensor 70 issues an alarm, and the negative pressure wind speed detection sensor 70 sends an alarm signal to the control module. When the control module receives the alarm signal, the control module controls the power equipment of the conveyor line 20, the electromagnetic switch valve on the blowing device 50, the electromagnetic switch valve on the air extraction end 61, and the driver 41 of the transfer device 40 to shut down. After the staff has performed maintenance and adjustments on the cup dust removal mechanism, the cup dust removal mechanism is restarted to continue normal dust removal and cleaning of the cups 10. Furthermore, as shown in FIG1 , the cup dust removal mechanism is provided with a counter 91 at a position near the box entrance 32 on the conveyor line 20. The counter 91 is electrically connected to the control module and accurately counts the number of cups 10 that enter the receiving cavity 31 for dust removal and cleaning.

[0086] In some embodiments of the present application, as shown in FIG2 , the cup dust removal mechanism is further equipped with a negative pressure digital display 71, which is electrically connected to the negative pressure wind speed detection sensor 70. The negative pressure digital display 71 displays the negative pressure wind speed in the receiving cavity 31 detected by the negative pressure wind speed detection sensor 70 in real time, so that the staff can directly observe the negative pressure digital display 71 to understand the working status of the negative pressure wind speed in the receiving cavity 31.

[0087] The dust and / or foreign matter attached to the cavity wall and outer wall of the inner cavity 13 of the support cup 10 generally carry static charges, so that the dust and / or foreign matter can stubbornly adhere to the cavity wall and outer wall of the inner cavity 13 of the support cup 10, making it difficult to blow the dust and / or foreign matter off the support cup 10. In view of this, in some embodiments of the present application, as shown in Figures 1, 3 and 4, the support cup dust removal mechanism also includes an ion wind generator 80, which is installed on the box body 30, and the air outlet of the ion wind generator 80 is connected to the accommodating cavity 31, and the air outlet of the ion wind generator 80 is set above the inlet section 411, and the air outlet of the ion wind generator 80 is generally aligned to blow ion wind toward the box inlet 32 ​​and the inlet section 411. The ionic charge of the ionized wind is used to neutralize the static charge of the dust and / or foreign matter, thereby removing the static charge of the dust and / or foreign matter and eliminating the electrostatic adsorption capacity of the dust and / or foreign matter, so that the dust and / or foreign matter attached to the cup 10 can be blown away from the cup 10 as thoroughly as possible, thereby improving the cleanliness of the dust removal and cleaning of the cup 10.

[0088] In the embodiment of the present application, the design of the cup dust removal mechanism specifically adopts the following scheme: the cup dust removal mechanism includes a conveyor line 20, a box 30, a transfer device 40, an air blowing device 50, an air extraction device 60, a negative pressure wind speed detection sensor 70, an ion wind generator 80 and a counter 91. The conveyor line 20 passes through the receiving cavity 31 of the box 30 and is used to convey the cup 10. The transfer device 40 is provided with a transfer track 410, which has an entrance section 411, an exit section 412, and a working section 413 located between the entrance section 411 and the exit section 412. The entrance of the entrance section 411 and the exit of the exit section 412 are respectively connected to the conveyor line 20, and the projection of the working section 413 does not overlap with the projection of the conveyor line 20. A plurality of blowing nozzles 51 are arranged in sequence along the arc direction of the working section 413 directly above the entire working section 413, and the entire working section 413 is located directly below the range of the exhaust port 62. Accordingly, a through hole 11 is provided at the bottom of the support cup 10. During the process of blowing by the blowing device 50 and exhaust by the exhaust device 60, the exhaust volume of the exhaust device 60 is always greater than the blowing volume of the blowing device 50 per unit time. The transfer device 40 includes a driver 41, a drive disc 42, and a connecting plate 43. The driver 41 is drivably connected to the drive disc 42, which is driven by the driver 41 to rotate the drive disc 42, which in turn drives the cup 10 forward along a transfer track 410. The connecting plate 43 has an arcuate edge 45 that mates with the edge of the drive disc 42. The edge of the drive disc 42 and the arcuate edge 45 face each other to form the transfer track 410. An annular elastic sleeve is fixedly mounted on the circumferential edge of the drive disc 42 to increase the relative friction coefficient between the edge of the drive disc 42 and the outer wall of the cup 10, thereby reducing or even eliminating the frequency of relative slip between the drive disc 42 and the cup 10. An annular groove 12 is provided on the circumferential outer wall of the cup 10, corresponding to the circumferential edge of the drive disc 42 and the arcuate edge 45 of the connecting plate 43. The annular groove 12 mates with the edge of the drive disc 42 and the arcuate edge 45. A plurality of blowing nozzles 51 are selected, each of which has an air outlet configured as a linear air outlet 52, and the linear length directions of the linear air outlets 52 of two adjacent blowing nozzles 51 are perpendicular to each other. A negative pressure wind speed detection sensor 70 is installed in the accommodating cavity 31 and close to the air extraction end 61. The negative pressure wind speed detection sensor 70 is used to detect the negative pressure wind speed in the accommodating cavity 31. An ion wind generator 80 is installed in the box body 30, and the air outlet of the ion wind generator 80 is connected to the accommodating cavity 31. The air outlet of the ion wind generator 80 is arranged above the inlet section 411. Generally, the air outlet of the ion wind generator 80 is aligned to blow ion wind toward the box inlet 32 ​​and the inlet section 411. In addition, a counter 91 is provided on the conveying line 20, and the counter 91 accurately counts the number of cups 10 entering the accommodating cavity 31 for dust removal and cleaning.

[0089] According to another aspect of the present application, a battery production line is provided. The battery production line includes a cup dust removal mechanism as described above. The cup dust removal mechanism provided by the embodiment of the present application is used in the battery production line to remove dust from the cup 10 used to carry and transport the bare cell structure. During the dust removal and cleaning process, the transfer device 40 can move the cup 10 out of the conveyor line 20, and then the dust and / or foreign matter remaining on the cup 10 is blown away by the blowing device 50, and the dust and / or foreign matter are extracted by the exhaust device 60, thereby achieving the purpose of all-round dust removal and cleaning of the cup 10. In addition, since the transfer device 40 moves the cup 10 out of the conveyor line 20, the probability of the dust and / or foreign matter on the cup 10 falling on the conveyor line 20 after being blown away is reduced, which also reduces the possibility of dust and / or foreign matter contaminating the cup 10 again, thereby improving the cleaning effect of the dust removal and cleaning of the cup 10.

[0090] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
