Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery cell processing and detection, and in particular to a multi-size detection device for lithium battery cell processing. Background Art

[0002] In the prior art, lithium battery cells are the most basic component of batteries. They are usually electrochemical devices encapsulated in a metal shell for storing and releasing electrical energy. They convert chemical energy into electrical energy through chemical reactions and are the core components of batteries.

[0003] During the processing of lithium battery cells, it is usually necessary to perform puncture tests on the lithium battery cells to evaluate the safety performance of the batteries. However, existing lithium battery cell puncture detection equipment can often only detect cells of a specific size and lacks wide adaptability to cells of different sizes. As a result, in practical applications, it is necessary to prepare multiple sets of detection devices for cells of different sizes, which not only increases the equipment cost, but also reduces the detection efficiency. Moreover, for devices that require adjustment of the puncture needle position, if only a single driving method such as a cylinder is relied upon, the puncture needle position adjustment accuracy is often insufficient due to factors such as air pressure stability and cylinder wear, which not only affects the accuracy of the puncture detection, but also causes unnecessary damage to the battery cells, making the lithium battery cells prone to accidental collisions or excessive contact during the puncture process, resulting in increased wear of the puncture needle and shortened service life, thereby increasing maintenance costs and affecting the stability of the test results.

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiments of the present invention:

[0032] Please refer to Figures 1 to 7 As shown, a multi-size detection device for lithium battery cell processing includes a workbench 1, a protective cover 2 is fixedly connected to the top of the workbench 1, a placement rack 3 is fixedly connected at the center of the top of the workbench 1, and the placement rack 3 is arranged in the protective cover 2, and also includes: a multi-size adaptation puncture mechanism 4 and a synchronous loosening auxiliary optimization mechanism 5, and the multi-size adaptation puncture mechanism 4 is arranged at the upper end of the workbench 1, and the synchronous loosening auxiliary optimization mechanism 5 is arranged at the lower end of the workbench 1;

[0033] The multi-size adaptable puncture mechanism 4 is used to adapt the size of the lithium battery cell for puncture;

[0034] The synchronous loosening auxiliary optimization mechanism 5 is used to assist in optimizing the harmful gas generated by the punctured lithium battery cell;

[0035] The multi-size adaptable puncture mechanism 4 includes a side plate 401 symmetrically fixedly connected to the top of the workbench 1 with the placement rack 3 as the center, and the side plate 401 is arranged on the outside of the protective cover 2, and a two-way reciprocating screw rod 402 is rotatably connected between the middle parts of the side plates 401, and the left end of the two-way reciprocating screw rod 402 penetrates the side plate 401 and is fixedly connected to a rotating rod, and a limit rod 403 is symmetrically fixedly connected between the side plates 401 with the two-way reciprocating screw rod 402 as the center, and the limit rod 403 and the two-way reciprocating screw rod 402 are both arranged through the protective cover 2, and the two-way reciprocating screw rod 402 is movably connected to the lower end of the protective cover 2;

[0036] The outer surface of the bidirectional reciprocating screw rod 402 is symmetrically threadedly connected with a Z-shaped bending plate 404, and the Z-shaped bending plate 404 is arranged in the protective cover 2. The lower end of the Z-shaped bending plate 404 is slidably connected with the limit rod 403, and the upper end of the Z-shaped bending plate 404 is fixedly connected with a cylinder 405.

[0037] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting a multi-size adaptive puncture mechanism 4 and utilizing the bidirectional reciprocating screw 402 to drive the Z-shaped bending plate 404 by thread, the position of the puncture needle 407 can be adjusted, so that the puncture needle 407 and the lithium battery cell to be punctured and tested always maintain an appropriate distance, avoiding accidental collision or excessive contact between the puncture needle 407 and the lithium battery cell during the puncture process, thereby reducing excessive impact on the lithium battery cell and the degree of wear on the puncture needle 407, extending the service life of the puncture needle 407, and by adjusting the distance between the puncture needle 407 and the lithium battery cell, it can be ensured that each puncture meets the preset standard, thereby obtaining a more reliable and accurate detection result. Compared with the method of adjusting the stroke of the cylinder 405, not only will the puncture needle 407 not be unable to adjust the position to the required accuracy due to reasons such as air pressure stability and wear of the cylinder 405, but there is also no need to design a complex control system to accurately control the movement of the cylinder 405, thereby effectively reducing the complexity and operation difficulty of the equipment.

[0038] Further examples:

[0039] Please refer to Figures 1 to 7As shown, the synchronous loosening auxiliary optimization mechanism 5 includes an exhaust fan 501 fixedly connected to the upper end of the rear side of the protective cover 2, and the side of the exhaust fan 501 away from the protective cover 2 is fixedly connected with an air duct 502, and the lower end of the workbench 1 is fixedly connected with a processing box 503, and the end of the air duct 502 away from the exhaust fan 501 passes through and is fixedly connected to the upper end of the processing box 503, and the middle part of the front side of the processing box 503 passes through and is slidably connected with an activated carbon adsorption plate 504, and the two sides of the lower end of the processing box 503 are symmetrically passed through and fixedly connected with exhaust ducts 505, and the protective cover 2 is fixedly connected with a one-way air intake valve. When the exhaust fan 501 is running, the external fresh air can be introduced into the interior of the protective cover 2 through the one-way air intake valve, and then the air inside the protective cover 2 (or the harmful gas generated by the puncture of the lithium battery cell) is introduced into the air duct 502 through the exhaust fan 501, and then introduced into the processing box 503 through the air duct 502, so as to complete the air replacement inside the protective cover 2;

[0040] A linkage shaft 506 is rotatably connected to the exhaust pipe 505, and a wind wheel 507 is fixedly connected to the outer surface of the linkage shaft 506. The wind wheel 507 is arranged in the exhaust pipe 505. Follower wheels 508 are symmetrically fixedly connected to the outer surfaces of both ends of the linkage shaft 506. The outer surface of the follower wheel 508 is annularly and equidistantly fixedly connected to the first protrusion 509;

[0041] Both sides of the lower end of the processing box 503 are symmetrically penetrated with through grooves 515, and an L-shaped follower slide plate 510 is slidably connected in the through grooves 515. A telescopic rod 511 and a return spring 512 are symmetrically fixedly connected between the bottom of the L-shaped follower slide plate 510 and the inner bottom wall of the through groove 515, and the return spring 512 is sleeved on the outer surface of the telescopic rod 511;

[0042] A second protrusion 513 is fixedly connected to the top of one end of the L-shaped follower slide plate 510 facing the follower wheel 508, and the second protrusion 513 is arranged below the follower wheel 508. The second protrusion 513 and the first protrusion 509 are both arranged in a hemispherical shape, and the first protrusion 509 is used to push the second protrusion 513;

[0043] A multiple cross-bar frame 514 is fixedly connected between the L-shaped follower slides 510, and the multiple cross-bar frame 514 is arranged below the activated carbon adsorption plate 504. The multiple cross-bar frame 514 is used to intermittently beat the activated carbon adsorption plate 504, and initially the multiple cross-bar frame 514 is in contact with the lower surface of the activated carbon adsorption plate 504.

[0044] The effects achieved by this embodiment are as follows: Compared with the prior art, through the setting of the synchronous loosening auxiliary optimization mechanism 5, when dealing with the harmful gases generated by the punctured lithium battery cell, the wind flow is used as the power source, and the rotation of the wind wheel 507 is used to drive the follower wheel 508 to rotate synchronously, and the first protrusion 509 is combined with the extrusion design of the second protrusion 513, so that the multi-cross rod frame 514 can intermittently beat the activated carbon adsorption plate 504 below the activated carbon adsorption plate 504, so that the substances adsorbed on the upper surface of the activated carbon adsorption plate 504 can be loosened, and this automatic loosening design effectively prevents the activated carbon from The adsorption plate 504 is clogged due to long-term use, and its good adsorption performance is maintained, thereby extending the service life of the activated carbon adsorption plate 504, and due to the design of the multi-cross rod frame 514, it can evenly cover a larger area under the activated carbon adsorption plate 504 and beat at multiple positions, thereby increasing the uniformity of the beating, ensuring that the adsorbed material on the surface of the activated carbon adsorption plate 504 is fully and evenly loosened, preventing local excessive blockage or insufficient loosening. Compared with relying solely on airflow flushing, this physical contact design is more direct and effective, and can more thoroughly restore the adsorption capacity of the activated carbon.

[0045] The complete usage steps and working principle of the above embodiment are as follows:

[0046] The following is the working process of the multi-size adaptable puncture mechanism 4 adapting to the size of the lithium battery cell for puncture:

[0047] It should be noted in advance that if Figure 1 As shown, the protective cover 2 is set to be transparent and fixed on the top of the workbench 1. At the same time, a protective door that can be rotated on the protective cover 2 is symmetrically set on the front side of the protective cover 2. Figure 2 A placement rack 3 is fixedly arranged at the top center of the workbench 1. The placement rack 3 is used to place the lithium battery cells to be tested. When in use, the staff can first open the protective door on the front side of the protective cover 2 so that the lithium battery cells can be placed on the upper surface of the placement rack 3 for subsequent puncture detection steps. The specific puncture detection steps are shown below;

[0048] Before the puncture detection step is performed on the lithium battery cell, the positions of the puncture needles 407 on both sides can be adjusted accordingly according to the size of the lithium battery cell to be detected, so that the distance between the puncture needles 407 and the lithium battery cell is always kept the same, such as Figure 2As shown, the left end of the bidirectional reciprocating screw rod 402 passes through the side plate 401 and is fixedly connected to a rotating rod. When adjusting the distance between the puncture needle 407 and the lithium battery cell, the staff can drive the bidirectional reciprocating screw rod 402 to rotate between the two side plates 401 by rotating the rotating rod. Since the outer surface of the bidirectional reciprocating screw rod 402 is threadedly provided with a Z-shaped bending plate 404, and the upper end of the Z-shaped bending plate 404 is fixedly provided with a cylinder 405, and the output end of the cylinder 405 passes through the Z-shaped bending plate 404 and is fixedly connected to a fixed plate 406, and the puncture needle 407 is fixedly provided on the opposite side of the two fixed plates 406, when the bidirectional reciprocating screw rod 402 rotates between the two side plates 401, the Z-shaped bending plate 404 on it can be driven to synchronously move in the bidirectional direction through the threaded connection. The outer surface of the reciprocating screw rod 402 moves left and right to change the distance between the puncture needle 407 and the lithium battery cell. During puncture, the cylinders 405 operate synchronously. The two fixed plates 406 can be driven by the cylinder 405 to move toward each other, and the puncture needle 407 can be driven to move in the direction of the lithium battery cell to perform puncture detection on the lithium battery cell. The puncture needles 407 on both sides are adjusted by adjusting the bidirectional reciprocating screw rod 402. Compared with directly using the cylinder 405 to drive the puncture needle 407, since the size of the lithium battery cell varies depending on the model, manufacturer or design, by first using the bidirectional reciprocating screw rod 402 to adjust the position of the puncture needle 407, it can be ensured that no matter how the size of the lithium battery cell changes, the puncture needle 407 can be accurately positioned to a position that maintains an appropriate distance from the lithium battery cell. This adjustment method provides high flexibility, so that the same set of mechanisms can be applicable to lithium battery cells of various sizes. In addition, it is difficult to simultaneously meet the needs of precise adjustment and stable puncture by directly using the cylinder 405 or the two-way reciprocating screw rod 402 to move the puncture needle 407. In particular, when the size of the lithium battery cell varies greatly, a single driving source cannot accurately control the position of the puncture needle 407, resulting in inaccurate puncture or damage to the battery cell. The two-step design first uses the two-way reciprocating screw rod 402 to adjust to ensure the position of the puncture needle 407, and then uses the cylinder 405 to complete the puncture action, which can greatly improve the accuracy and stability of the puncture. During the puncture process, by adjusting the position of the puncture needle 407, the puncture needle 407 can always maintain an appropriate distance from the lithium battery cell to be punctured and tested, thereby avoiding accidental collision or excessive contact between the puncture needle 407 and the lithium battery cell during the puncture process, thereby reducing excessive impact on the lithium battery cell and the degree of wear of the puncture needle 407, extending the service life of the puncture needle 407, and by adjusting the distance between the puncture needle 407 and the lithium battery cell, it can be ensured that each puncture meets the preset standard, thereby obtaining a more reliable and accurate test result. Compared with the method of adjusting the stroke of the cylinder 405, not only will the puncture needle 407 not be unable to adjust the position to the required accuracy due to reasons such as air pressure stability and wear of the cylinder 405,Furthermore, there is no need to design a complex control system to accurately control the movement of the cylinder 405, thereby effectively reducing the complexity and operating difficulty of the equipment;

[0049] Please refer to the above working process Figures 1 to 7 .

[0050] The following is the working process of the synchronous loose auxiliary optimization mechanism 5 for auxiliary optimization treatment of harmful gases generated by puncturing lithium battery cells:

[0051] In the process of penetration testing of lithium battery cells, such as Figure 3 As shown, since an exhaust fan 501 is provided at the upper end of the rear side of the protective cover 2, a processing box 503 is fixedly provided at the lower end of the workbench 1, and an air duct 502 is fixedly connected between the processing box 503 and the exhaust fan 501, when in use, the exhaust fan 501 is started and operated, and harmful gases generated by the lithium battery cells during puncture can be introduced into the interior of the processing box 503 through the air duct 502, as shown in FIG. Figure 4 As shown, because the activated carbon adsorption plate 504 is slidably connected to the middle of the front side of the treatment box 503, and the air duct 502 is connected and arranged above the rear side of the activated carbon adsorption plate 504, when the air duct 502 introduces the harmful gas generated by the puncture of the lithium battery cell into the interior of the treatment box 503, the setting of the activated carbon adsorption plate 504 can adsorb these harmful components on the surface of the activated carbon adsorption plate 504, thereby achieving the purpose of purifying the exhaust gas, as shown in FIG. Figure 5 , Figure 6 as well as Figure 7 As shown, exhaust pipes 505 are fixedly connected and arranged on both sides of the lower end of the processing box 503. The clean gas after adsorption and filtration by the activated carbon adsorption plate 504 can be discharged to the outside through the exhaust pipes 505 on both sides. Since a linkage shaft 506 is rotatably arranged on the exhaust pipe 505, and a wind wheel 507 is fixedly arranged on the outer surface of the linkage shaft 506, and the wind wheel 507 is arranged in the exhaust pipe 505, the exhaust movement of the exhaust pipe 505 and the impact of the wind flow can drive the wind wheel 507 to rotate synchronously on the exhaust pipe 505 in coordination with the linkage shaft 506. At this time, since the outer surfaces of both ends of the linkage shaft 506 are symmetrically fixedly connected with the follower wheels 508 with the wind wheel 507 as the center, when the wind wheel 507 rotates, the linkage shaft 506 and the follower wheels 508 on both sides can rotate synchronously, and according to Figure 5 and Figure 6As shown, inside the treatment box 503, a multi-cross rod frame 514 is arranged below the activated carbon adsorption plate 504, and L-shaped follow-up slide plates 510 are symmetrically fixedly arranged at both ends of the multi-cross rod frame 514, and the L-shaped follow-up slide plate 510 is slidably arranged in the through grooves 515 symmetrically opened on both sides of the treatment box 503, and a telescopic rod 511 and a return spring 512 are fixedly arranged between the L-shaped follow-up slide plate 510 and the inner bottom wall of the through groove 515, and the outward end of the L-shaped follow-up slide plate 510 is arranged close to the follow-up wheel 508, and the outer surface of the follow-up wheel 508 is annularly and equidistantly fixed with first protrusions 509, so that when the follow-up wheel 508 rotates, the first protrusions 509 thereon synchronously follow the rotation centered on the linkage shaft 506. The L-shaped follower slide 510 is rotated, and a second protrusion 513 of the same shape as the first protrusion 509 is fixedly arranged on the top of one end of the L-shaped follower slide 510 close to the follower wheel 508, and the first protrusion 509 and the second protrusion 513 are both set to a hemispherical shape. Therefore, when the follower wheel 508 rotates to drive the first protrusion 509 to rotate synchronously, the first protrusion 509 will contact the surface of the second protrusion 513 one by one. By utilizing the design of the first protrusion 509, an extrusion force can be formed on the second protrusion 513 during the rotation movement, so that the second protrusion 513 moves downward synchronously, thereby driving the L-shaped follower slide 510 to slide synchronously inside the through groove 515. At the same time, the return spring 512 and the telescopic rod 511 arranged between the L-shaped follower slide 510 and the through groove 515 are synchronously The L-shaped follow-up slide 510 contracts, and the multiple cross-bar frame 514 installed between the L-shaped follow-up slides 510 will move synchronously under the activated carbon adsorption plate 504. When the first protrusion 509 continues to rotate and loses contact with the second protrusion 513, the pressure on the second protrusion 513 disappears. Under the elastic force of the reset spring 512, the L-shaped follow-up slide 510 can be driven to move upward, so that the multiple cross-bar frame 514 returns to the initial position and contacts the lower surface of the activated carbon adsorption plate 504. By utilizing the rotation of the multiple first protrusions 509 and the follow-up design of the second protrusion 513, the multiple cross-bar frame 514 can intermittently move on the lower surface of the activated carbon adsorption plate 504 and intermittently slap the lower surface of the activated carbon adsorption plate 504, thereby facilitating The substances adsorbed on the upper surface of the activated carbon adsorption plate 504 are loosened to reduce the clogging of the activated carbon adsorption plate 504, thereby extending the service life of the activated carbon adsorption plate 504. The design of the multi-cross rod frame 514 can evenly cover a large area below the activated carbon adsorption plate 504 and beat it at multiple positions, thereby increasing the uniformity of the beating, ensuring that the adsorbed substances on the surface of the activated carbon adsorption plate 504 are fully and evenly loosened, preventing local excessive blockage or insufficient loosening. Compared with the existing anti-blocking design, the use of physical beating can directly act on the surface of the activated carbon adsorption plate 504, effectively loosening those stubborn adsorbents that are difficult to remove by airflow, and avoiding the blockage problem caused by long-term accumulation.The activated carbon adsorption plate 504 can be kept in good working condition for a longer period of time, and the replacement frequency is reduced, thereby reducing the maintenance cost and extending the service life of the overall equipment;

[0052] Among them, the wind flow in the exhaust pipe 505 is used to directly drive the wind wheel 507 to rotate, thereby driving the entire loose structure to work, without additional energy consumption, achieving efficient use of energy, and at the same time the entire loosening process is automatically completed by air flow drive, without manual intervention, improving the automation level and operation convenience of the equipment, and the linkage design ensures the synchronous movement between the various components, so that the multi-cross rod frame 514 can be evenly and orderly moved and flapped under the activated carbon adsorption plate 504, ensuring the consistency and stability of the loosening effect;

[0053] Please refer to the above working process Figures 1 to 7 .
