Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to a conveying device for lithium battery processing. Background Technology

[0002] The lithium battery production process is complex, involving multiple stages such as electrode preparation, cell assembly, packaging, and formation and capacity testing. The conveying system, acting as the "artery system" connecting these processes, transports the various components of the lithium battery in an orderly and efficient manner for subsequent processing. Electrode sheets are one of the most crucial components in a lithium battery. With increasingly stringent technical requirements, electrode sheets are becoming thinner, resulting in lower strength. Conveyor belts are commonly used for conveying electrode sheets. However, existing electrode sheet conveying devices still have some problems in their operation, as detailed below:

[0003] Existing lithium battery electrode sheet conveying devices use conveyor belts, which present two problems. First, the electrodes vibrate during transport, and since they often have metal dust and debris adhering to them, the vibration causes these particles to rub against the surface, scratching the electrodes and severely impacting their safety during subsequent use. Second, to ensure the reliability of the electrodes after transport and storage, existing technologies use robotic arms at the end of the conveyor belt. Some robotic arms use clamping methods, while others use negative pressure adsorption. Regardless of the method, pressure is applied to the electrodes. Improper adjustment of the clamping force can cause the electrodes to bend and deform, rendering them unusable. Improper adjustment of the negative pressure adsorption force can cause unevenness in the electrodes, also damaging them and rendering them unusable. Therefore, we propose a conveying device for lithium battery processing. Summary of the Invention

[0015] The present invention has the following beneficial effects:

[0016] 1. This lithium battery processing conveying equipment, equipped with an external conveying component, transports lithium battery electrode sheets to be stored into a collection and storage component. During this process, airflow from the top thoroughly cleans the upper surface of the electrode sheets to remove dust and impurities. After being transported into the collection and storage component, airflow from the bottom lifts the electrode sheets. This lifting process not only cleans the lower surface of the electrode sheets but also uses the upward force of the airflow to raise the electrode sheets. Once lifted, the sheets fall directly into the collection and storage component for stacking and storage. This airflow-based conveying and storage method, compared to traditional clamping or negative pressure adsorption, maximizes the integrity of the electrode sheets. Furthermore, the entire process automatically cleans the electrode sheets, ensuring that they are not affected by impurities and thus do not suffer quality problems in subsequent processes.

[0017] 2. This lithium battery processing conveying equipment is equipped with a rotatable transfer component. The internal structure of the transfer component allows it to continuously move back and forth between the external conveying component and the collection and storage component during its rotation. During this movement, the electrode sheets continuously conveyed from the external conveying component are lifted and moved. Furthermore, by setting the air pressure inside the base component to a state that continuously decreases during storage within the collection and storage component, each electrode sheet can be stably stored after moving to its corresponding height within the collection and storage component. The gradually decreasing air pressure also does not affect the electrode sheets already placed above, thus ensuring the overall storage effect. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The lithium battery processing conveying equipment involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-4A conveying device for lithium battery processing includes a main frame 1, which consists of two upper and lower discs connected by a C-shaped rod. A gas collecting ring 2 is fixedly installed inside the upper disc of the main frame 1, and a filter structure is provided inside the gas collecting ring 2 to filter impurities in the gas. A base support assembly 3 is fixedly installed inside the lower disc of the main frame 1. An air pump 4 is fixedly installed on one side of the top of the upper disc of the main frame 1, and a gas guide pipe 5 is fixedly connected to one end of the air pump 4. An external gas guide pipe 6 is fixedly connected through the top of the gas collecting ring 2. An external conveying assembly 7 is fixedly installed on the side of the main frame 1. A rotating ring 8 is rotatably installed between the upper and lower discs of the main frame 1, and a collection and storage assembly 9 is embedded in the rotating ring 8. A rotary drive motor 10 is fixedly installed at the middle of the top of the main frame 1. A transmission rod 11 is fixedly installed on the output shaft of the rotary drive motor 10, and a transfer assembly 12 is fixedly installed at the bottom of the transmission rod 11.

[0035] Compared with existing technologies, this application, by incorporating an external conveying component 7, allows for the transport of lithium battery electrode sheets to be stored into the collection and storage component 9. During this process, airflow from the top thoroughly cleans the upper surface of the electrode sheets, removing dust and impurities. After being transported into the collection and storage component 9, airflow from the bottom lifts the electrode sheets. This lifting process not only cleans the lower surface of the electrode sheets but also utilizes the upward force of the airflow to elevate them. Once lifted, the electrode sheets fall directly into the collection and storage component 9 for stacking and storage. This airflow-based transport and storage method, compared to traditional clamping or negative pressure adsorption, maximizes the integrity of the electrode sheets, and throughout the entire process... Automatic cleaning of the electrode sheets ensures that they are not affected by impurities and thus do not suffer quality problems in subsequent processes. A rotatable transfer component 12 is incorporated, whose internal structure allows it to continuously move back and forth between the external conveying component 7 and the collection and storage component 9 during rotation. This movement lifts and moves the electrode sheets continuously conveyed from the external conveying component 7. Furthermore, by setting the air pressure inside the base support component 3 to gradually decrease during storage within the collection and storage component 9, each electrode sheet can be stably stored after moving to its corresponding height within the component 9. The gradually decreasing air pressure also does not affect the electrode sheets already placed above, thus ensuring the overall storage effect.

[0036] Please see Figure 1-5A conveying device for lithium battery processing includes a base support assembly 3, which includes a tray 31. An inner partition 32 is fixedly installed inside the tray 31, dividing the interior of the tray 31 into two areas: an outer ring groove 33 and an inner channel 34. A first cover plate 35 is fixedly installed above the outer ring groove 33, and a second cover plate 36 is fixedly installed above the inner channel 34.

[0037] In this embodiment, it should be noted that one end of the first cover plate 35 is located upstream of the rotating ring 8 in the rotation direction and is spaced apart from the inner partition plate 32. The width of this gap is less than or equal to the cross-sectional width of the collection and storage component 9. The bottom end of the collection and storage component 9 is slidably disposed against the upper surface of the first cover plate 35. The upper part of the second cover plate 36 is connected to the air guide pipe 5, and one end of the second cover plate 36 is provided with an air outlet groove. This air outlet groove is connected to the bottom end of the upper collection and storage component 9. In this way, the airflow delivered from above can be guided into the collection and storage component 9 through the inner channel 34, thereby blowing the brought-in electrode sheet upward for storage. The blown airflow can also clean the metal impurities and dust on the lower surface of the electrode sheet at the same time. The cleaned impurities are discharged through the collection and storage component 9 to the upper part of the outer base component 3. Then, the subsequent rotation of the collection and storage component 9 will concentrate and scrape the impurities into the outer ring groove 33, ensuring the quality of the electrode sheet while avoiding dust and impurities from polluting the environment.

[0038] Please see Figure 2 and Figure 12 A lithium battery processing conveying device includes an outer conveying component 7, which includes an outer frame 71. An air inlet 72 is provided on one side of the top of the outer frame 71. An inner groove is provided in the middle of the bottom of the outer frame 71. A bottom plate 73 is fixedly installed at both ends of the inner groove. An elastic pad 74 is fixedly installed on the upper surface of the bottom plate 73. An upper support plate 75 is fixedly installed on the top of the elastic pad 74. A plurality of conveying rollers 76 are evenly arranged on the upper support plate 75.

[0039] In this embodiment, it should be noted that cavities are provided on both sides of the outer frame 71, and a through-flow long air channel is provided between the bottom end of the cavity and the inner groove. The upper support plate 75 is segmented, and a segment with the same length as the electrode plate is provided at the end where the outer frame 71 is connected to the rotating ring 8. The conveying roller 76 can sink as the elastic pad 74 is compressed. In this way, the compression of the upper support plate 75 by the transfer component 12 during the lateral movement causes the conveying roller 76 to sink, thereby causing the electrode plate on the conveying roller 76 to fall onto the transfer component 12. Furthermore, the elastic pad 74 is always compressed when there is an overlap between the transfer component 12 and the upper support plate 75, ensuring that the electrode plate can be well conveyed into the collection and storage component 9 throughout the process.

[0040] Please see Figure 1-8A lithium battery processing conveying device includes a collection and storage component 9. The collection and storage component 9 includes a housing 91. A handle 92 is fixedly installed at one end of the housing 91. Slag discharge grooves 93 are respectively opened on both sides of the housing 91. An air inlet groove 94 is opened at the bottom end of the housing 91. Straight rail grooves 95 are respectively opened on both sides inside the housing 91. A bottom bracket 96 is fixedly installed at the four corners of the bottom end inside the housing 91. A balance holding structure 97 is movably installed inside the straight rail groove 95. Exhaust baffles 98 are fixedly installed at both ends inside the housing 91. A support storage structure 99 is uniformly fixedly installed on the outer surface of the exhaust baffles 98. Exhaust grooves 910 are respectively opened at both ends of the top end of the housing 91. A sealing plate 911 is movably installed at the other end of the housing 91.

[0041] In this embodiment, it should be noted that the outer shell 91 is inserted and movably disposed within the rotating ring 8, the opening of the slag discharge trough 93 faces downward, the air inlet trough 94 is connected to the air outlet trough at one end of the second cover plate 36, the bottom bracket 96 is hollow, and the bottom end of the outer shell 91 has an air inlet that communicates with the interior of the bottom bracket 96, the top end of the bottom bracket 96 is connected to the interior, the exhaust baffle 98 is spaced apart from the inner wall of the outer shell 91, and the exhaust trough 910 is connected to the bottom end of the bottom support assembly 3. In this way, the air supply inside the bottom support assembly 3 allows the electrode plate entering the bottom end of the outer shell 91 to be blown upward by the airflow, and at the same time, the airflow is used to maintain the balance structure. The 97 self-locking mechanism ensures that the four corners of the electrode sheet can fit against the four balance holding structures 97, thus ensuring that the electrode sheet can always move upward with the maximum windward surface under the action of airflow, ensuring the upward movement effect of the electrode sheet. During the upward movement, the balance holding structure 97 can also lift the supporting storage structure 99 it passes through, so as to ensure that the electrode sheet is driven through the supporting storage structure 99, thereby realizing the subsequent storage of the electrode sheet by the supporting storage structure 99. After the conveying is completed, when the balance holding structure 97 moves downward in the absence of airflow, the balance holding structure 97 can unlock itself, so as to automatically pass through the position of passing through the supporting storage structure 99, ensuring the cyclic use of the entire structure.

[0042] Please see Figure 7-14 A lithium battery processing conveying device includes a balance holding structure 97, which includes a main block 971. A movable clamp 972 is fixedly installed on the side of the main block 971. A baffle 973 is rotatably installed on the top of the main block 971. A limiting groove 974 is formed on the lower surface of the baffle 973. A locking groove 975 is formed on the main block 971 and the baffle 973. A locking rod 976 is movably installed inside the locking groove 975. An air-receiving bottom block 977 is fixedly installed at the bottom end of the locking rod 976.

[0043] In this embodiment, it should be noted that rollers are embedded on both sides of the movable locking head 972. The movable locking head 972 is slidably disposed inside the straight rail groove 95. The limiting groove 974 can be engaged and limited to fit the surface of the electrode sheet. A limiting ring is provided on the locking rod 976 and is disposed inside the main body block 971. The top end of the locking rod 976 can be moved through to the upper surface of the baffle 973. Thus, when the balance holding structure 97 is placed on the base bracket 96, the locking rod 976 automatically inserts into the baffle 973. The baffle 973 is restricted from rotating, so that when the electrode plate below is blown up and contacts the limiting groove 974, it can be stably locked. During the subsequent ascent, the airflow below can also be used to keep the air-receiving base block 977 moving up to fit the bottom of the main body block 971. During the descent, the weight of the air-receiving base block 977 causes the locking rod 976 to release the rotation restriction on the baffle 973. Then, when passing through the support and storage structure 99, it automatically rotates to ensure that it can effectively pass through the support and storage structure 99 and fall to the bottom for the next use.

[0044] Please see Figure 9-11 A conveying device for lithium battery processing includes a support and storage structure 99, which includes a support base block 991. One end of the support base block 991 is fixedly connected to a gas guide hose 992, and the other end of the support base block 991 is provided with a groove. A support pad 993 is fixedly installed in the groove, and a storage tray 994 is fixedly installed on the support pad 993. A limiting groove 995 is opened inside the support base block 991, and a limiting lever 996 is movably installed inside the support base block 991.

[0045] In this embodiment, it should be noted that a side groove is provided on one side of the supporting base block 991 for the balance holding structure 97 to move. One end of the air guide hose 992 is sealed and connected through the exhaust baffle 98, and the other end is provided with a sealing expansion membrane. One end of the limiting rod 996 is set against the sealing expansion membrane, and the bottom end is provided with a protruding plate in the limiting inner groove 995. The storage tray 994 is provided with a protruding edge on the side near the air guide hose 992, and the top of the protruding edge is set higher than the bottom end of the limiting rod 996 when the electrode plate is not placed. The top of the protruding edge is at the same height as the upper surface of the electrode plate after it is placed on the storage tray 994. In this way, after the electrode plate is placed on the storage tray 994, the airflow inside the exhaust baffle 98 can squeeze and expand the sealing expansion membrane, thereby pushing the limiting rod 996 to move laterally. The bottom end of the limiting rod 996 will fit against the upper surface of the electrode plate and limit and lock it, thereby ensuring the stable placement of the electrode plate and the collection and storage component 9 and preventing the electrode plate from falling off due to subsequent airflow.

[0046] Please see Figure 3 and 12A lithium battery processing conveying device includes a transfer assembly 12, which includes a turntable 121. A transmission rod is rotatably connected to the lower surface of the turntable 121. A straight rod 122 is rotatably connected to one end of the transmission rod. A vertical rod 123 is fixedly installed on the upper surface of the straight rod 122. A bracket 124 is fixedly installed at the top of the vertical rod 123. A limit pressure rod 125 is fixedly installed on the side of the vertical rod 123.

[0047] In this embodiment, it should be noted that limit sleeves are fitted on both ends of the straight rod 122. The limit sleeves are fixedly installed on the lower surfaces of the outer frame 71 and the main frame 1, respectively. A boss is provided at the end of the bracket 124 near the turntable 121, and the bracket 124 has an H-shaped structure. There are two limit pressure rods 125, which are symmetrically arranged below the bracket 124. An inclined insertion surface is provided below the end of the bracket 124 near the outer conveying component 7. This inclined insertion surface can press down on the upper support plate 75. In this way, the rotation of the turntable 121 can drive the bracket 124 to reciprocate. During the process of the bracket 124 being inserted into and leaving the outer frame 71, the limiting pressure rod 125 presses down on the upper support plate 75 to make the electrode sheet fall stably on the surface of the bracket 124. After the bracket 124 is completely removed from the inner part of the outer frame 71, the end of the limiting pressure rod 125 with the inclined insertion surface leaves the surface of the upper support plate 75 and releases the pressing action, thus ensuring the stable delivery of the electrode sheet throughout the process.

[0048] Working principle: The air pump 4 and rotary drive motor 10 are started. The air pump 4 generates airflow that enters the inner channel 34 through the main air guide pipe 5. Inside the outer frame 71, the rotating conveyor rollers 76 guide the electrode sheet from the front. The rotating turntable 121 drives the bracket 124 to reciprocate laterally within the outer frame 71 via the straight rod 122. During insertion, the limiting pressure rod 125 moves the upper support plate 75 downward, causing the conveyor rollers 76 to detach from the lower surface of the electrode sheet and fall onto the bracket 124. Then, the electrode sheet is moved laterally out of the outer frame 71, completing the transfer. The transferred electrode sheet enters the bottom of the outer shell 91. The airflow in the inner channel 34 blows the electrode sheet upward. After the electrode sheet is blown up, its four corners contact the limiting grooves 974. The airflow continues to increase, blowing the electrode sheet and the balance holding structure 97 upward as a whole. After reaching the corresponding height, the air pump 4 is turned off. Under its own weight, the electrode sheet falls onto the storage tray 994, and the supporting pad... 993 is compressed, and the air-receiving bottom block 977 moves down, causing the locking rod 976 to release the restriction on the baffle 973. During the overall descent of the balance holding structure 97, when it passes the supporting storage structure 99, the baffle 973 automatically rotates to a vertical position and finally falls onto the bottom bracket 96. The airflow generated by the intake slot 94 when it is restarted will fill the sealing expansion membrane when it flows in the exhaust baffle 98, thereby pushing the limit lever 996 out. The removed limit lever 996 will fit against the upper surface of the electrode plate, and the metal debris blown down by the airflow will be discharged from the slag discharge slot 93 on the side. The airflow in the exhaust baffle 98 will be filtered by the bottom bracket assembly 3 and transported to the external conveying assembly 7 through the external air guide pipe 6 to clean the upper surface of the electrode plate. When the electrode plates inside a collection and storage assembly 9 are stacked, the rotating ring 8 is rotated so that the next collection and storage assembly 9 rotates to the position of the corresponding external conveying assembly 7 to collect again, and the above operation continues.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
