Description

Technical Field

[0001] The invention relates to the technical field of battery electrode processing, and in particular to an automatic recycling extrusion molding machine for collecting battery pole piece waste in the process of battery electrode processing. Background Art

[0002] In the process of processing and manufacturing battery electrodes, the electrode raw materials need to be cut, and usually the foil ears on both sides of the lithium battery electrode need to be cut off; the traditional process usually adopts the method of forming a negative pressure in the collection box to collect the waste, but due to the limited space of the collection box, these strip-shaped corner waste materials are light and bulky, and they are very easy to occupy space, so that the collection box will be full in a short time. The operator must frequently clean the collection box, which not only increases the labor intensity of the operator and reduces the work efficiency, but also stops the production operation due to frequent cleaning operations, reduces the process production efficiency, increases the production cycle and cost, and seriously restricts the lithium battery process. It has become one of the problems that need to be solved urgently in the development of the lithium battery industry.

[0003] In the prior art, an improved structural form is proposed to address the problem that battery electrode waste is light and fluffy, easily occupies space, and causes the collection box to be full in a short time. The patent with application number 202210647012.8 and titled "A Battery Electrode Waste Collection Device" provides a battery electrode waste collection device, which adjusts the different braking distances of the push plate by controlling the different levels of telescopic states of the multi-stage telescopic sleeve, thereby achieving the goal of integrating the push plate for pressing and pushing materials, and can improve the throughput and space utilization of the material collection box. Although it can solve the problem that the battery waste is light and fluffy and easily occupies space, so that the collection box will be full in a short time to a certain extent, in engineering practice, since the different levels of telescopic expansion of the multi-stage telescopic sleeve are used to adjust the different braking distances of the push plate, the tube diameter of the telescopic sleeve must be gradually reduced, which determines that the stroke of the whole set of telescopic sleeves cannot be too long, and due to the structure of the telescopic rod itself, the rigidity is weak, and it cannot provide a large enough thrust to compact the fluffy waste to a deeper depth, which makes the compaction rate of the collection equipment not high, thereby affecting the efficiency of the whole set of battery electrode waste collection.

[0004] In view of this, there is an urgent need for an automatic recycling and extrusion molding machine for battery electrode waste, which can not only effectively solve the problem that the battery electrode waste is light and fluffy and easily takes up space, but also make full use of the space of the collection device, further compress the waste in the receiving chamber, and improve the throughput and space utilization of the receiving box, ensuring the service life while realizing precise intelligent and automated control.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] like Figure 1As shown, according to some exemplary embodiments, an automatic recycling extrusion molding machine for battery electrode waste is shown, including an extrusion module 20, an extrusion module housing 10 covered on the extrusion module 20, and a feed bin assembly 30 arranged between the extrusion module housing 10 and the extrusion module 20, wherein one end of the feed bin assembly 30 is connected to the extrusion module 20, and the other end of the opposite arrangement penetrates the extrusion module housing 10 and is fixed to the top surface of the extrusion module housing 10 to form a feed channel for materials to enter the extrusion module 20. As a result, the battery electrode waste generated in the battery production process can conveniently enter the interior of the extrusion module through the feed bin assembly, and then be compressed by the extrusion module, thereby improving the throughput and space utilization of the receiving box.

[0034] In the embodiment of the present application, the extrusion module housing 10 can be of various appropriate structures, preferably, Figure 2 As shown, the extrusion module housing 10 is welded by panels and support ribs, so that it has sufficient rigidity to load and withstand uncertain position loads. Specifically, the extrusion module housing 10 includes a housing frame 11, an electric control room door 12 and a safety door 13, wherein the housing frame 11 is connected end to end by angle steel to form a frame structure with a storage cavity, and the electric control room door 12 and the safety door 13 are lockably connected to the housing frame 11 so that they can rotate. Therefore, the extrusion module housing formed by welding panels and support ribs provides a support platform for accommodating the extrusion module, which ensures the safety of the extrusion module operation, and also provides an operating platform for collecting, temporarily storing and transporting battery electrode waste, providing a carrier for realizing continuous automated operations.

[0035] In the preferred embodiment of the present application, Figure 3 and Figure 4 As shown, the extrusion module 20 includes a telescopic assembly 21, an extrusion bin 22 and a flip door 23, wherein the telescopic assembly 21 includes a fixed portion and a moving portion, the fixed portion of the telescopic assembly 21 is fixed to the extrusion module housing 10, and the moving portion of the telescopic assembly 21 penetrates the internal cavity of the extrusion bin 22 and is telescopically arranged relative to the extrusion bin 22; the flip door 23 is fixed on the end side of the extrusion bin 22 away from the telescopic assembly 21, and is flippably closed with the extrusion bin 22; thus, by the moving portion of the telescopic assembly penetrating the internal cavity of the extrusion bin and acting together with the flip door of the flip-closed arrangement of the extrusion bin, it can be ensured that the battery waste is fully compacted inside the internal cavity of the extrusion bin, thereby solving the problem that light and fluffy battery electrode waste easily occupies space, and improving the throughput and space utilization of the receiving box.

[0036] Specifically, the telescopic assembly 21 includes a telescopic component 210, a flange 211, a piston head 212 and an extrusion plate 214, wherein the telescopic component 210 is connected to the piston head 212 as a whole after passing through the flange 211, and is arranged to move together; the piston head 212 is fixed on the end side surface of the telescopic component 210, and is located on the other side away from the telescopic component 210; the extrusion plate 214 is fixed to the telescopic component 210 through the piston head 212, and is located at the farthest end away from the flange 211. Therefore, the piston head is arranged between the extrusion plate and the telescopic component, which ensures the force area when the pressure is transmitted from the telescopic component to the extrusion plate, thereby ensuring the stability and reliability of the compression process; through the telescopic movement of the telescopic assembly, the piston head then drives the extrusion plate to move telescopically relative to the extrusion chamber, thereby realizing the extrusion of the battery electrode waste inside the extrusion chamber, solving the problem that the light and fluffy battery electrode waste easily occupies space.

[0037] Furthermore, in order to ensure the reliability and stability of the force transmission between the telescopic assembly 210 and the extrusion plate 214, the telescopic assembly 210 and the piston head 212 are rotatably arranged. Specifically, the telescopic assembly 210 is detachably rotatably connected to the piston head 212 via the pin 213.

[0038] In order to facilitate the fixation of the telescopic assembly 210, a connecting plate 215 is also included, which is parallel to and spaced from the flange 211 and is located at the other end away from the piston head 212. At least two guide supports 216 are also provided between the connecting plate 215 and the flange 211. One end of the guide support 216 is fixed against the end side of the connecting plate 215, and the other end is fixed against the end side of the flange 211. Thus, the at least two guide supports provided between the connecting plate and the flange provide a fixed installation space for the telescopic assembly 210. Specifically, after the telescopic assembly 210 passes through the through hole opened in the middle of the connecting plate 215, it extends along the length direction of the guide support 216 and is fixed to the flange 211. Optionally, the telescopic assembly 210 is an electric cylinder assembly, the cylinder body of the electric cylinder assembly is fixed on the flange 211, and after the piston rod of the electric cylinder assembly passes through the flange 211, it is telescopically arranged along the length direction of the guide support 216. Therefore, by selecting the electric cylinder assembly as the telescopic assembly, high-precision motion control can be achieved in a complex working environment, and it has the advantages of low noise, energy saving, high rigidity, etc. It effectively solves the defects of the prior art using a multi-stage telescopic sleeve structure, such as insufficient rigidity, limited stroke, and inability to provide sufficient thrust, resulting in the inability to compact the waste. It can significantly improve the compaction rate of the collection equipment while intelligently and automatically controlling the time.

[0039] In order to prevent the telescopic assembly 21 from being damaged by foreign objects dropped during operation, a cover plate 217 is also included, which is fixed between the connecting plate 215 and the flange 211, and the cover plate 217 is located above the top of the guide support 216. This ensures that the telescopic assembly 210 running between the connecting plate 215 and the flange 211 is provided with more comprehensive protection, so as to ensure that the telescopic assembly 21 can operate continuously and safely.

[0040] Optionally, in order to facilitate the control and adjustment of the gap between the piston head 212 and the extrusion plate 214 and avoid the wear caused by the direct contact between the piston head 212 and the extrusion plate 214, at least one slider 218 is detachably arranged on the piston head 212, and the sliders 218 are arranged at intervals on the outer peripheral side of the piston head 212 and against the extrusion plate 214. Specifically, by replacing sliders 218 of different thicknesses, the gap between the piston head 218 and the extrusion plate 214 can be achieved. Preferably, the slider 218 is made of antistatic nylon material. Therefore, the slider made of antistatic nylon material can well avoid the harm to the operation of the equipment caused by the static electricity generated by the piston head during the extrusion molding process.

[0041] Optionally, in order to ensure that the telescopic assembly 210 can smoothly move and compress the piston head 212, at least two guide shafts 219 are provided between the flange 211 and the piston head 212, one end of the guide shaft 219 is fixed against the end side of the flange 211, and the other end oppositely arranged is fixed on the end side of the piston head 212. Preferably, the guide shaft 219 and the guide support 216 are coaxially arranged on both sides of the flange 211. Therefore, the rigidity of the telescopic assembly after installation and fixation is significantly improved through the coaxially arranged guide shaft and guide support, ensuring the smooth transmission of pressure.

[0042] In the preferred embodiment of the present application, Figure 5 As shown, the piston head 212 includes a base 2121, a first mounting plate 2122, a second mounting plate 2123 and a support plate 2124, wherein the base 2121 is fixed on the end side surface of the first mounting plate 2122, and the second mounting plate 2123 is arranged on both sides of the first mounting plate 2122; the second mounting plate 2123 is spaced apart from the first mounting plate 2122, and is fixed as a whole with the first mounting plate 2122 through the support plate 2124, and is arranged to move together.

[0043] Optionally, in order to ensure the reliability of the connection between the guide shaft 219 and the piston head 212, at least one guide sleeve 2126 is also arranged on the side of the first mounting plate 2122. The guide sleeve 2126 is adapted to the guide shaft 219, thereby ensuring that the guide shaft 219 can be quickly and securely connected to the first mounting plate 2122, thereby ensuring the overall rigidity of the telescopic assembly 21.

[0044] In summary, the telescopic assembly provided by the present invention provides a fixed installation space for the telescopic component through at least two guide supports arranged between the connecting plate and the flange; a piston head is arranged between the extrusion plate and the telescopic component to ensure the force area when the pressure is transmitted from the telescopic component to the extrusion plate, thereby ensuring the stability and reliability of the compression process; through the telescopic movement of the telescopic assembly, the piston head then drives the extrusion plate to move telescopically relative to the extrusion chamber, thereby realizing the extrusion of the battery electrode waste inside the extrusion chamber, solving the problem that the light and fluffy battery electrode waste is very easy to occupy space; through the guide shaft and guide support arranged on the coaxial line, the rigidity of the telescopic assembly after installation and fixation is significantly improved, ensuring the smooth transmission of pressure; by selecting the electric cylinder assembly as the telescopic assembly, high-precision motion control can be achieved in a complex working environment, and at the same time it has the advantages of low noise, energy saving, high rigidity, etc., effectively solving the defects of the prior art using a multi-stage telescopic sleeve structure, insufficient rigidity, limited stroke, and inability to provide a sufficiently large thrust, resulting in the inability to compact the waste, and can significantly improve the compaction rate of the collection equipment while intelligently and automatically controlling the time.

[0045] In the preferred embodiment of the present application, Figure 6 As shown, the extrusion bin 22 includes a bracket 221, a bin body 222 and a feed port 223, wherein the bracket 221 is a supporting beam structure truss formed by U-shaped steel through welding, riveting or bolting; the bin body 222 is arranged on the top surface of the bracket 221 and is fixed to the bracket 221; the feed port 223 is an opening opened on the top surface of the bin body 222 and connected to the internal cavity of the bin body 222.

[0046] Optionally, in order to facilitate real-time grasp of the working conditions in the extrusion bin 22, the bin body 222 includes a first observation chamber 2221, a blanking chamber 2222 and a molding chamber 2223, wherein the first observation chamber 2221 is connected to the molding chamber 2223 through the blanking chamber 2222, and the feed port 223 is opened on the top surface of the first observation chamber 2221. Thus, after the material passes through the feed port 223, it enters the blanking chamber 2222 under the action of the telescopic assembly 21, and then enters the molding chamber 2223 to be further compacted and molded. Thus, by dividing the extrusion bin into the first observation chamber, the blanking chamber and the molding chamber, the integration of different functions is realized, thereby ensuring the operability and maintainability of the extrusion bin.

[0047] Optionally, in order to timely judge the material status inside the extrusion bin 22, a first observation plate 2221a is further provided on the side of the first observation chamber 2221, and the first observation plate 2221a is made of a transparent material, so as to directly understand the real-time working conditions inside the first observation chamber 2221.

Preferably, in order to improve the convenience of operation, the first observation plate 2221a and the second observation plate 2222a are located on the same side of the extrusion bin 22.

[0048] In summary, the extrusion bin provided by the present invention divides the extrusion bin into a first observation chamber, a blanking chamber and a forming chamber to achieve integration of different functions, thereby ensuring the operability and maintainability of the extrusion bin; by means of the first observation plate and the second observation plate arranged on the first observation chamber and the blanking chamber, it is possible to timely understand and grasp the real-time situation of different processes inside the extrusion bin, thereby improving the flexibility, reliability and safety of the overall extrusion bin operation process.

[0049] In the preferred embodiment of the present application, Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the flip door 23 includes a bolt plate 231, a movable plate 232 and at least one driving rod 233, wherein the bolt plate 231 is fixed on the extrusion bin 22 and extends in a direction away from the telescopic assembly 21; the movable plate 232 is rotatably arranged on the bolt plate 231 and is arranged to be openable and closed with the extrusion bin 22; one end of the driving rod 233 is rotatably fixed on the extrusion bin 21, and the other end of the opposite arrangement is drivably connected to the movable plate 233. In a preferred embodiment of the present invention, the driving rod 233 is rotatably fixed on the bracket 221 of the extrusion bin 22, so as to obtain a more stable support. Thus, through the driving connection in which one end is rotatably fixed on the extrusion bin and the other end is drivably connected to the movable plate, the movable plate can be rotated relative to the extrusion bin under the action of the driving rod, thereby realizing the switching of the closed or open state of the extrusion bin.

[0050] Optionally, the movable plate 232 is welded by a panel and a support beam, and has sufficient rigidity to load and withstand uncertain position loads, and specifically includes at least one rotation hole 2321 and at least one lifting hole 2322 opened on the support beam, wherein the rotation hole 2321 is located at the end side of the support beam of the movable plate 232, and the lifting hole 2322 is set on the side of the support beam of the movable plate 232, extending along the width direction of the movable plate 232. Specifically, the rotation holes 2321 are opened in pairs on the outermost support beams in the width direction of the movable plate 232, and are located on the top end side of the support beam. Preferably, the lifting holes 2322 are set in pairs on the outermost support beams in the width direction of the movable plate 232, and extend in the direction away from the movable plate 232 along the width direction of the movable plate 232. Further, it also includes at least one plug-in plate hole 2323 opened on the outermost support beam in the width direction of the movable plate 232, and the plug-in plate hole 2323 is located at the other end away from the rotation hole 2321.

[0051] Optionally, the driving rod 233 includes a fixed seat 2331 and a first telescopic cylinder 2332, wherein one end of the first telescopic cylinder 2332 is rotatably connected to the extrusion bin 22 through the fixed seat 2331, and the other end arranged oppositely is drivably connected to the movable plate 232.

Thus, a connecting rod structure is formed between the first telescopic cylinder, the movable plate and the extrusion bin, and the closing and opening of the movable plate and the extrusion bin are realized under the driving of the telescopic movement of the telescopic end.

[0052] In summary, the flip door provided by the present invention forms a connecting rod structure between the first telescopic cylinder and the movable plate and the extrusion bin, and the closing and opening of the movable plate and the extrusion bin are achieved under the telescopic movement of the telescopic end; one end is rotatably fixed to the extrusion bin, and the other end is drivably connected to the movable plate, so that under the action of the driving rod, the movable plate can be rotated relative to the extrusion bin, thereby achieving the switching of the closed or open state of the extrusion bin.

[0053] Optionally, in order to further improve the compaction of the battery electrode waste and improve the efficiency of the operation, as Figure 6 and Figure 8 As shown, the extrusion die set 20 further includes at least one locking device 24 that can be releasably locked with the flip door 23, one end of the locking device 24 is fixed to the extrusion bin 22, and the other end that is oppositely arranged can be releasably locked with the flip door 23. By locking the flip door, it is ensured that the internal cavity of the extrusion bin remains fixed during operation, so as to continuously compact the added electrode waste, and further improve the throughput and space utilization of the receiving box.

[0054] Specifically, the locking device 24 includes a second mounting seat 214, a second telescopic cylinder 243 and a plug plate 244, wherein the second mounting seat 214 is fixed on the extrusion bin 22 and is arranged against the outer side of the flip door 23; the plug plate 244 is fixed on the second mounting seat 214 by the second telescopic cylinder 243 and is arranged to be telescopic relative to the second mounting seat 214. The plug plate 244 can switch between the locked and opened states with the flip door 23 by driving the second telescopic cylinder 243, thereby realizing the locking and releasing of the flip door 23.

[0055] Optionally, the second mounting base 241 is welded from a plate and has a bracket with an internal cavity. The fixed end of the second telescopic cylinder 243 is detachably fixed to the end side of the second mounting base 241 away from the flip door 23. The telescopic end of the second telescopic cylinder 243 is fixed to the plug plate 244 as a whole and is movably arranged. Thus, the plug plate 244 can be driven to be telescopic relative to the flip door 23 by the telescopic end of the second telescopic cylinder 243, thereby achieving locking and releasing of the flip door 23. For example, after driving the plug plate 244 to penetrate the bolt plate 231, it passes through the plug plate hole 2323 on the movable plate 232 in the flip door 23, thereby achieving stable locking between the movable plate 232 and the bolt plate 231.

[0056] Optionally, in order to ensure that the plug plate 244 can accurately and conveniently pass through the through hole on the bolt plate 231, it also includes a plug plate guide seat 242 arranged on the edge of the through hole of the bolt plate 231.
