Description

Technical Field

[0001] This invention relates to the field of lithium battery production technology, and in particular to a material handling device and a material handling method thereof. Background Technology

[0002] In the lithium battery production process, the Mylar coating process is a key step in assembling battery cells. The Mylar coating machine coats the battery cells with Mylar film according to the process specifications. The purpose of the Mylar film is to prevent short circuits caused by contact between the battery cell and the aluminum casing.

[0003] Mylar membranes are thin and tend to stick together due to static electricity during storage. Traditional Mylar membrane retrieval methods use top suction cups, often resulting in multiple sheets being retrieved. This multiple-sheet retrieval at the coating station causes equipment alarms and shutdowns, impacting production time and rendering coated cells unusable, thus affecting yield. Furthermore, cells without detected multiple sheets being manufactured into batteries and sold on the market pose a short-circuit risk, potentially causing equipment fires and irreparable damage to personal safety and property. Summary of the Invention

[0004] The primary objective of this invention is to provide a feeding device to ensure that Mylar films are fed sheet by sheet.

[0005] Another object of the present invention is to provide a material handling method for a material handling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A feeding device for removing Mylar films one sheet at a time, comprising:

[0008] The magazine mechanism has an internal accommodating space for accommodating the Mylar membrane, and the magazine mechanism has a feeding port communicating with the accommodating space along a first direction;

[0009] The material handling mechanism includes a first material handling suction cup assembly and a second material handling suction cup assembly arranged at intervals along a second direction. The first material handling suction cup assembly and the second material handling suction cup assembly can be independently moved along the first direction to the material handling port to suck out the Mylar film.

[0010] The material dispensing mechanism is located on the side of the magazine mechanism along the second direction. The dispensing mechanism includes a support frame and a dispensing assembly and a return assembly both mounted on the support frame. Each dispensing assembly includes a dispensing component and a dispensing drive component. The dispensing drive component is fixed to the support frame to drive the dispensing component to move along the second direction. The dispensing component includes a dispensing cylinder and a detection suction cup. The dispensing cylinder drives the detection suction cup to move along the first direction. The suction force of the detection suction cup is less than the suction force of the second material-retrieving suction cup assembly. The return assembly includes a return component and a return drive component. The return drive component is fixed to the support frame to drive the return component to move along both the first and second directions.

[0011] The first direction and the second direction intersect.

[0012] Preferably, the material handling mechanism further includes a linear drive module and a sliding bracket. The sliding bracket is connected to the output end of the linear drive module. The linear drive module is used to drive the sliding bracket to move in a third direction. The first material handling suction cup assembly and the second material handling suction cup assembly are both disposed on the sliding bracket.

[0013] Wherein, the third direction, the first direction, and the second direction intersect each other.

[0014] Preferably, along the second direction, the first material-picking suction cup assembly is provided at the middle position of the sliding bracket. The first material-picking suction cup assembly includes a first material-picking cylinder and a first material-picking suction cup. The first material-picking cylinder is fixed to the sliding bracket, and the first material-picking suction cup is fixed to the output end of the first material-picking cylinder.

[0015] Along the second direction, the sliding bracket is provided with the second material picking suction cup assembly on both sides. The second material picking suction cup assembly includes a second material picking cylinder and a second material picking suction cup. The second material picking cylinder is fixed to the sliding bracket, and the second material picking suction cup is fixed to the output end of the second material picking cylinder. An avoidance groove is provided on the second material picking suction cup.

[0016] Along the second direction, the material distribution mechanism is provided on both sides of the magazine mechanism.

[0017] Preferably, the return component includes a connecting plate and a connecting claw. The connecting plate is connected to the output end of the return drive component, and the connecting plate is provided with a connecting claw on the side of the connecting plate in the second direction away from the return drive component.

[0018] Preferably, the material return drive includes a first material return cylinder and a second material return cylinder. The first material return cylinder is fixedly connected to the support frame. The output end of the first material return cylinder is fixedly connected to the second material return cylinder to drive the second material return cylinder to move along the second direction. The output end of the second material return cylinder is fixedly connected to the connecting plate to drive the connecting plate and the connecting claw to move along the first direction.

[0019] Preferably, the material distribution assembly further includes a blocking bracket, which is connected to the output end of the material distribution drive. The material distribution drive is used to drive the blocking bracket to move along the second direction, and the material distribution component is disposed along the first direction on the side of the blocking bracket opposite to the magazine mechanism.

[0020] Preferably, the material distribution components are provided on both sides of the support frame along the third direction, and the material return components are provided at the middle position of the support frame along the third direction;

[0021] Wherein, the third direction, the first direction, and the second direction intersect each other.

[0022] Preferably, it further includes a fixed bracket, and along the second direction, the side wall of the magazine mechanism is fixedly connected to the top of the support frame via the fixed bracket.

[0023] Preferably, the magazine mechanism includes a first magazine, a second magazine, a limiting block, and a connecting bracket. The first magazine and the second magazine are spaced apart and arranged opposite to each other along the second direction. The first magazine and the second magazine are connected by the connecting bracket. The limiting block is fixedly connected to the connecting bracket. The fixed bracket and the support frame are symmetrically arranged on the first magazine and the second magazine along the second direction. The accommodating space is formed between the first magazine, the second magazine, and the limiting block.

[0024] Wherein, the third direction, the first direction, and the second direction intersect each other.

[0025] The present invention also relates to a material handling method of the aforementioned material handling device, comprising the following steps:

[0026] The first and second material suction cup assemblies move along the first direction to the material inlet and adsorb the Mylar film.

[0027] The second material suction cup assembly moves away from the material inlet along the first direction and sucks out the portion of the Mylar film corresponding to the second material suction cup assembly from the material inlet;

[0028] The material distribution drive unit drives the material distribution component to enter the material picking port and the second material picking suction cup assembly along the second direction;

[0029] The dispensing cylinder drives the detection suction cup to move along the first direction to above the second material suction cup assembly. After the detection suction cup adsorbs the Mylar film, the dispensing cylinder drives the detection suction cup to reset along the first direction.

[0030] The detection suction cup determines whether Mylar film is adsorbed;

[0031] When Mylar film is detected adsorbed on the detection suction cup, the return material drive unit drives the return material unit to move along the first direction and the second direction to the space between the detection suction cup and the second material picking suction cup assembly;

[0032] The material distribution drive unit drives the material distribution unit to exit from between the material inlet and the second material suction cup assembly along the second direction;

[0033] The material return drive unit drives the material return unit to move along the first direction to the material inlet, so as to return the Mylar film adsorbed by the detection suction cup to the accommodating space;

[0034] When it is detected that the detection suction cup has not adsorbed any Mylar film, the first material-picking suction cup assembly moves along the first direction to be flush with the second material-picking suction cup assembly, thus completing the picking up of a single Mylar film.

[0035] Compared with the prior art, the material handling device of this invention has the following advantages:

[0036] In this invention, during Mylar film feeding, the first and second feeding suction cup assemblies first move along a first direction to the feeding port of the clip mechanism. Then, the first feeding suction cup assembly supports the Mylar film at the feeding port, and the second feeding suction cup assembly sucks out the portion of the Mylar film corresponding to the second feeding suction cup assembly from the feeding port along the first direction. Next, the dispensing drive drives the dispensing component to move along a second direction between the feeding port and the second feeding suction cup assembly, allowing the dispensing cylinder of the dispensing component to drive the detection suction cup to move along the first direction above the second feeding suction cup assembly and adsorb the Mylar film sucked out by the second feeding suction cup assembly. Then, the dispensing cylinder drives the detection suction cup to reset along the first direction. If two or more Mylar films are adsorbed on the second feeding suction cup assembly, the detection suction cup can pick up the Mylar film after resetting, and the vacuum induction of the detection suction cup is not zero at this moment, indicating that Mylar film is adsorbed on the detection suction cup. Therefore, the return drive drives the return component along... The first and second directions move the component between the detection suction cup and the second material-taking suction cup assembly. Then, the material-dispensing drive drives the material-dispensing component to exit between the material-taking port and the second material-taking suction cup assembly, allowing the Mylar film adsorbed by the detection suction cup to fall onto the return component. Then, the return component drives the return component to move along the first direction to the material-taking port, sending the Mylar film adsorbed by the detection suction cup back into the accommodating space. When only one Mylar film is adsorbed on the second material-taking suction cup assembly, since the suction force of the detection suction cup is less than that of the second material-taking suction cup assembly, the detection suction cup cannot pick up the Mylar film on the second material-taking suction cup assembly after resetting. Therefore, the vacuum sensing of the detection suction cup is zero at this moment, and it is determined that no Mylar film is adsorbed on the detection suction cup. Finally, after only one Mylar film is adsorbed on the second material-taking suction cup assembly, the first material-taking suction cup assembly moves along the first direction to be flush with the second material-taking suction cup assembly to complete the material taking of a single Mylar film.

[0037] Therefore, the material handling device of this application, through the above steps, can take out Mylar film sheet by sheet during the material handling process of Mylar film, thereby ensuring the smooth progress of subsequent cell coating work, avoiding alarm shutdown of the coating equipment, ensuring production efficiency, preventing cell scrap and affecting the yield of high-quality products, and also reducing the risk of short circuit in the finished battery, thus protecting personal and property safety.

[0056] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0057] In the description of this invention, it should be understood that the term "comprising" as used in this specification means the presence of the stated features, integers, steps, operations, parts, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts, components, and / or groups thereof. It should be understood that when we say a part is "connected" to another part, it can be directly connected to the other part, or there may be intermediate parts. The term "and / or" as used herein includes all or any unit and all combinations of one or more associated listed items.

[0058] like Figures 1 to 17 As shown, the present invention relates to a material handling device for taking out Mylar films one by one, comprising: a clip mechanism 1, a material handling mechanism 2, and a material dispensing mechanism 3.

[0059] Combination Figures 1 to 4 As shown, the magazine mechanism 1 has an internal accommodating space for accommodating Mylar film, and the magazine mechanism 1 has a feeding port 11 communicating with the accommodating space along the first direction.

[0060] The material handling mechanism 2 includes a first material handling suction cup assembly 21 and a second material handling suction cup assembly 22 arranged at intervals along the second direction. The first material handling suction cup assembly 21 and the second material handling suction cup assembly 22 can move independently along the first direction to the material handling port 11 to suck out the Mylar film.

[0061] The material distribution mechanism 3 is located on the side of the magazine mechanism 1 along the second direction. The material distribution mechanism 3 includes a support frame 31 and a material distribution component 32 and a material return component 33, both of which are mounted on the support frame 31. The material distribution component 32 includes a material distribution element 321 and a material distribution drive element 322. The material distribution drive element 322 is fixed on the support frame 31 to drive the material distribution element 321 to move along the second direction. The material distribution element 321 includes a material distribution cylinder 3211 and a detection suction cup 3212. The material distribution cylinder 3211 is used to drive the detection suction cup 3212 to move along the first direction. The suction force of the detection suction cup 3212 is less than the suction force of the second material pick-up suction cup component 22. The material return component 33 includes a material return element 331 and a material return drive element 332. The material return drive element 332 is fixed on the support frame 31 to drive the material return element 331 to move along the first direction and the second direction.

[0062] The first direction and the second direction intersect.

[0063] In this invention, during Mylar film feeding, the first feeding suction cup assembly 21 and the second feeding suction cup assembly 22 first move along a first direction to the feeding port 11 of the clip mechanism 1. Then, the first feeding suction cup assembly 21 supports the Mylar film at the feeding port 11, and the second feeding suction cup assembly 22 sucks out the portion of the Mylar film corresponding to the second feeding suction cup assembly 22 from the feeding port 11 along the first direction. Next, the dispensing drive 322 drives the dispensing component 321 to move along a second direction between the feeding port 11 and the second feeding suction cup assembly 22, allowing the dispensing component 321 to... The dispensing cylinder 3211 drives the detection suction cup 3212 to move along the first direction to above the second material-taking suction cup assembly 22, and adsorbs the Mylar film sucked up by the second material-taking suction cup assembly 22. Then, the dispensing cylinder 3211 drives the detection suction cup 3212 to reset along the first direction. When two or more Mylar films are adsorbed on the second material-taking suction cup assembly 22, the detection suction cup 3212 can pick up the Mylar film after resetting, and the vacuum induction of the detection suction cup 3212 at this moment is not zero, indicating that Mylar film is adsorbed on the detection suction cup 3212, thereby triggering the return drive unit 33. 2. Drive the return component 331 to move along the first and second directions to between the detection suction cup 3212 and the second picking suction cup assembly 22. Then, the dispensing drive component 322 drives the dispensing component 321 to exit from between the picking port 11 and the second picking suction cup assembly 22, allowing the Mylar film adsorbed by the detection suction cup 3212 to fall onto the return component 331. Then, the return drive component 332 drives the return component 331 to move along the first direction to the picking port 11, sending the Mylar film adsorbed by the detection suction cup 3212 back into the receiving space. Only one Mylar film is adsorbed on the second picking suction cup assembly 22. When the Mylar film is being picked up, because the suction force of the detection suction cup 3212 is less than that of the second picking suction cup assembly 22, the detection suction cup 3212 cannot pick up the Mylar film on the second picking suction cup assembly 22 after resetting. Therefore, the vacuum induction of the detection suction cup 3212 is zero at this moment, and it is determined that no Mylar film is adsorbed on the detection suction cup 3212. Finally, after only one Mylar film is adsorbed on the second picking suction cup assembly 22, the first picking suction cup assembly 21 moves along the first direction to be flush with the second picking suction cup assembly 22 to complete the picking of a single Mylar film.

[0064] Therefore, the material handling device of this application, through the above steps, can take out Mylar film sheet by sheet during the material handling process of Mylar film, thereby ensuring the smooth progress of subsequent cell coating work, avoiding alarm shutdown of the coating equipment, ensuring production efficiency, preventing cell scrap and affecting the yield of high-quality products, and also reducing the risk of short circuit in the finished battery, thus protecting personal and property safety.

[0065] It should be noted that when the detection suction cup 3212 picks up the Mylar film above the second material pick-up suction cup assembly 22, the detection suction cup 3212 may pick up the Mylar film one by one, or multiple Mylar films may be bonded together by electrostatic force, allowing the detection suction cup 3212 to pick up multiple Mylar films at once, ultimately keeping only one Mylar film on the second material pick-up suction cup assembly 22.

[0066] In this embodiment, the vacuum degree of the first material-picking suction cup assembly 21 and the second material-picking suction cup assembly 22 is -90 kPa, and the vacuum degree of the detection suction cup 3212 is -20 kPa. This ensures that the suction force generated by the second material-picking suction cup assembly 22 is greater than the suction force generated by the detection suction cup 3212, so that when there is only one Mylar film on the second material-picking suction cup assembly 22, it will not be sucked away by the detection suction cup 3212.

[0067] In this embodiment, the material handling mechanism 2 further includes a linear drive module 23 and a sliding bracket 24. The sliding bracket 24 is connected to the output end of the linear drive module 23. The linear drive module 23 is used to drive the sliding bracket 24 to move along a third direction. The first material handling suction cup assembly 21 and the second material handling suction cup assembly 22 are both disposed on the sliding bracket 24. The third direction, the first direction and the second direction intersect each other.

[0068] The first suction cup assembly 21 and the second suction cup assembly 22 are both mounted on the sliding bracket 24. The sliding bracket 24 is connected to the output end of the linear drive module 23. After the first suction cup assembly 21 and the second suction cup assembly 22 remove a single Mylar film, the linear drive module 23 drives the sliding bracket 24 to move along a third direction to pull the Mylar film away from the feeding port 11, which facilitates the subsequent transfer of the removed single Mylar film.

[0069] Preferably, along the second direction, a first material-picking suction cup assembly 21 is provided at the middle position of the sliding bracket 24. The first material-picking suction cup assembly 21 includes a first material-picking cylinder 211 and a first material-picking suction cup 212. The first material-picking cylinder 211 is fixed to the sliding bracket 24, and the first material-picking suction cup 212 is fixed to the output end of the first material-picking cylinder 211.

[0070] Along the second direction, a second material-picking suction cup assembly 22 is provided on both sides of the sliding bracket 24. The second material-picking suction cup assembly 22 includes a second material-picking cylinder 221 and a second material-picking suction cup 222. The second material-picking cylinder 221 is fixed to the sliding bracket 24, and the second material-picking suction cup 222 is fixed to the output end of the second material-picking cylinder 221. An avoidance groove 223 is provided on the second material-picking suction cup 222.

[0071] Along the second direction, both sides of the magazine mechanism 1 are provided with a material distribution mechanism 3.

[0072] That is, during material retrieval, the first material retrieval cylinder 211 drives the first material retrieval suction cup 212 to support the middle position of the material retrieval port 11 along the second direction, so as to support the middle position of the Mylar film. Then, the two second material retrieval cylinders 221 drive the two second material retrieval suction cups 222 to move to the two sides of the material retrieval port 11 along the second direction, and suck the Mylar film from both sides of the material retrieval port 11. At the same time, along the second direction, the clip mechanism 1 is provided with a material distribution mechanism 3 on both sides, so that the material distribution mechanism 3 on both sides can cooperate with the two second material retrieval suction cup assemblies 22 to perform material distribution work, so as to ensure the smooth extraction of a single Mylar film.

[0073] Furthermore, the return material component 331 includes a connecting plate 3311 and a connecting claw 3312. The connecting plate 3311 is connected to the output end of the return material drive component 332. The connecting plate 3311 is provided with a connecting claw 3312 on the side of the second direction away from the return material drive component 332, and the connecting claw 3312 corresponds to the clearance groove 223 on the second material suction cup 222.

[0074] The return component 331 includes a connecting plate 3311 and a connecting claw 3312. Driven by the return drive component 332, the connecting claw 3312 can return the Mylar film picked up by the detection suction cup 3212 to the feeding port 11. Simultaneously, the connecting claw 3312 corresponds to the clearance groove 223 of the second feeding suction cup 222. Therefore, before the second feeding suction cup 222 moves to the feeding port 11, the connecting claw 3312 first supports itself at the feeding port 11, and then the first feeding suction cup 212 and the second feeding suction cup 222 move to the feeding port. After the opening 11, the connecting claw 3312 enters the clearance groove 223 of the second material-picking suction cup 222. Finally, the return drive 332 drives the connecting claw 3312 to exit from the clearance groove 223 in the second direction. Therefore, by setting the connecting claw 3312, the Mylar film will not fall out of the picking port 11 when there is no support, and the Mylar film at the picking port 11 will be flat before the first material-picking suction cup 212 and the second material-picking suction cup 222 come close together, so that the first material-picking suction cup 212 and the second material-picking suction cup 222 can smoothly carry out the material picking work.

[0075] Furthermore, the material return drive component 332 includes a first material return cylinder 3321 and a second material return cylinder 3322. The first material return cylinder 3321 is fixedly connected to the support frame 31. The output end of the first material return cylinder 3321 is fixedly connected to the second material return cylinder 3322 to drive the second material return cylinder 3322 to move along the second direction. The output end of the second material return cylinder 3322 is fixedly connected to the connecting plate 3311 to drive the connecting plate 3311 and the connecting claw 3312 to move along the first direction.

[0076] By setting up the first return cylinder 3321 and the second return cylinder 3322, the connecting plate 3311 and the connecting claw 3312 can be driven to move along the first direction and the second direction, so as to cooperate in completing the material taking work of Mylar membrane.

[0077] In this embodiment, the material distribution assembly 32 further includes a blocking bracket 323, which is connected to the output end of the material distribution drive 322. The material distribution drive 322 is used to drive the blocking bracket 323 to move along the second direction. The material distribution component 321 is disposed along the first direction on the side of the blocking bracket 323 facing away from the magazine mechanism 1.

[0078] That is, the dispensing cylinder 3211 is fixed on the side of the blocking bracket 323 facing away from the magazine mechanism 1, so that when the blocking bracket 323 moves to the feeding port 11, the blocking bracket 323 can support the Mylar film at the feeding port 11. Before the second feeding suction cup assembly 22 moves to the feeding port 11 to pick up the material, the blocking bracket 323 can work with the connecting claw 3312 to support the material at the feeding port 11. During the process of the detection suction cup 3212 adsorbing excess Mylar film on the second feeding suction cup assembly 22, the blocking bracket 323 can also support the material at the feeding port 11 to prevent the Mylar film from falling out of the feeding port 11 and affecting normal material picking.

[0079] Preferably, the support frame 31 is provided with material distribution components 32 on both sides along the third direction, and the support frame 31 is provided with a material return component 33 at the middle position along the third direction; wherein the third direction, the first direction and the second direction intersect each other.

[0080] The support frame 31 is provided with material distribution components 32 on both sides along the third direction, so that the Mylar film on the second material picking suction cup assembly 22 is provided with detection suction cups 3212 on both sides along the third direction to perform material distribution work on the Mylar film, so as to ensure the smooth material distribution work.

[0081] The material handling device also includes a fixed bracket 4. Along the second direction, the side wall of the magazine mechanism 1 is fixedly connected to the top of the support frame 31 through the fixed bracket 4, so that the connection between the magazine mechanism 1 and the support frame 31 is more stable.

[0082] In this embodiment, the magazine mechanism 1 includes a first magazine 12, a second magazine 13, a limiting block 14, and a connecting bracket 15. The first magazine 12 and the second magazine 13 are spaced apart and arranged opposite to each other along the second direction. The first magazine 12 and the second magazine 13 are connected by the connecting bracket 15. The limiting block 14 is fixedly connected to the connecting bracket 15. The fixing bracket 4 and the support frame 31 are symmetrically arranged on the first magazine 12 and the second magazine 13 along the second direction. An accommodating space is formed between the first magazine 12, the second magazine 13, and the limiting block 14. The third direction, the first direction, and the second direction intersect each other.

[0083] The arrangement of the first clip 12, the second clip 13, the limiting block 14, and the connecting bracket 15 creates a stable storage space to accommodate multiple Mylar films stacked together.

[0084] Combination Figures 5 to 17 As shown, the present invention also relates to a material handling method of a material handling device, comprising the following steps:

[0085] The first suction cup assembly 21 and the second suction cup assembly 22 move along the first direction to the suction port 11 and adsorb the Mylar film.

[0086] The second material suction cup assembly 22 moves away from the material inlet 11 along the first direction and sucks out the portion of the Mylar film corresponding to the second material suction cup assembly 22 from the material inlet 11;

[0087] The material distribution drive 322 drives the material distribution component 321 to enter along the second direction between the material picking port 11 and the second material picking suction cup assembly 22;

[0088] The dispensing cylinder 3211 drives the detection suction cup 3212 to move along the first direction to above the second material suction cup assembly 22. After the detection suction cup 3212 adsorbs the Mylar film, the dispensing cylinder 3211 drives the detection suction cup 3212 to reset along the first direction.

[0089] The 3212 suction cup is used to determine whether Mylar film is adsorbed.

[0090] When Mylar film is detected adsorbed on the detection suction cup 3212, the return material drive 332 drives the return material 331 to move along the first direction and the second direction to the space between the detection suction cup 3212 and the second material pick-up suction cup assembly 22.

[0091] The material distribution drive 322 drives the material distribution component 321 to exit from between the material pick-up port 11 and the second material pick-up suction cup assembly 22 in the second direction;

[0092] The return drive unit 332 drives the return unit 331 to move along the first direction to the material inlet 11, so as to send the Mylar film adsorbed by the detection suction cup 3212 back into the accommodating space.

[0093] When it is detected that the detection suction cup 3212 has not adsorbed Mylar film, the first material suction cup assembly 21 moves along the first direction to be flush with the second material suction cup assembly 22;

[0094] The linear drive module 23 drives the sliding bracket 24 to move along a third direction, thereby driving the first material-picking suction cup assembly 21 and the second material-picking suction cup assembly 22 away from the material-picking port 11 along a third direction, thus completing the picking up of a single Mylar film.

[0095] In summary, the first material suction cup assembly 21, the second material suction cup assembly 22, the material distribution assembly 32, and the material return assembly 33 provided in this application have different applications at different stages. Thus, through the cooperation of the four components, the extraction of a single Mylar film can be achieved. In other words, the work can be completed by cooperating with fewer parts, which can reduce equipment costs and has high practicality.

[0096] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
