DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0041] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood as the usual meanings understood by those skilled in the art to which the present application belongs.

The terms "upper", "lower", "left", "right" and the like are only used to represent relative positional relationships, which may change accordingly when the absolute positions of the described objects change.

[0042] In the specific embodiments provided in the present application, an electrode core rubberizing detection device is provided, which is described with reference to Figures 1 to 9As shown, the battery cell adhesive detection device comprises a first magnetic drive circulating line 1 for conveying the first battery cell fixture 7, and a loading detection mechanism 2, an adhesive mechanism 3, a CCD detection mechanism 4, a ray detection mechanism 5 and a discharging detection mechanism 6 arranged in sequence along the conveying direction of the first magnetic drive circulating line 1. The loading detection mechanism 2 is used to convey the battery cell to the first battery cell fixture 7. The discharging detection mechanism 6 has a discharging logistics line 604 therein for conveying the qualified battery cell after detection to a designated area for storage. The adhesive mechanism 3 is used to paste a strip of adhesive on the middle position of the battery cell tab and two strips of adhesive on the opposite end face of the battery cell tab, so as to ensure the stability of the battery cell structure and improve the insulation and protection performance of the battery cell. The CCD detection mechanism 4 mainly detects the accuracy of the adhesive and the appearance quality of each part of the battery cell by using CCD vision technology. For example, the CCD detection mechanism 4 comprises a plurality of CCD detection components, including but not limited to an ear misplacement detection component (detecting whether there is a relative misplacement defect between each layer of the tab, whether the overall size and the distance from each end face position are defective, etc.), a large surface CCD detection component (used to detect whether there is a tail needle defect, adhesive position offset, surface contamination, black leakage, etc.), a tab folding detection component (detecting tab folding, wrinkling, side cracking, tab missing, etc.), and a battery cell end face detection component (detecting defects such as label and other paper foreign matter wrapped into the battery cell, missing tab, etc.).

[0043] In some embodiments, the CCD detection mechanism 4 is located downstream of the adhesive mechanism 3. The adhesive mechanism 3 and the CCD detection mechanism 4 work cooperatively to ensure the accurate position of the adhesive on the battery cell, high alignment consistency, and timely appearance detection after bonding to avoid defective products flowing into subsequent processes.

[0044] In some embodiments, referring to Figure 1As shown, based on the space occupancy rate in the production workshop and the radiation protection consideration, when the battery cell is detected by the ray, the ray detection mechanism 5 is independent of the first magnetic drive circulating line 1, that is, the ray detection mechanism 5 includes a second magnetic drive circulating line 8, a first carrying mechanism 801, and a ray detection device 802, the second magnetic drive circulating line 8 is slidably connected with a second battery cell jig 803 for placing the battery cell, the first carrying mechanism 801 is arranged between the first magnetic drive circulating line 1 and the second magnetic drive circulating line 8, and is used to carry the battery cell between the first battery cell jig 7 and the second battery cell jig 803. Specifically, the first carrying mechanism 801 is provided with at least two, and the two first carrying mechanisms 801 are located upstream and downstream of the second magnetic drive circulating line 8, respectively. The ray detection device 802 is located between the two first carrying mechanisms 801. The first carrying mechanism 801 located upstream can carry the battery cell of the first battery cell jig 7 to the second battery cell jig 803, so that the second battery cell jig 803 drives the battery cell to the ray detection device 802 located beside the second magnetic drive circulating line 8, and then the battery cell is detected by the ray detection device 802. The X-ray can be used to detect whether the pole piece of the battery cell is broken. After detection, the second battery cell jig 803 moves the detected battery cell to the first carrying mechanism 801 located downstream, and then the first carrying mechanism 801 located downstream carries the battery cell to the first battery cell jig 7 and carries out subsequent weighing detection, bottom surface detection and thickness detection.

[0045] In some embodiments, the second magnetic drive circulating line 8 includes a stator mechanism and a mover mechanism, wherein the stator mechanism is a guide rail for conveying the battery cell, and the mover mechanism is used to carry the second battery cell jig 803, so that the second battery cell jig 803 is slidably connected to the second magnetic drive circulating line 8. At the same time, the second magnetic drive circulating line 8 is arranged beside the first magnetic drive circulating line 1, and the battery cell is carried by the first carrying mechanism 801, so that the battery cell placed on the second battery cell jig 803 can complete the automatic re-inspection (X-ray detection) of the X-ray detection device in the form of automatic circulation of the magnetic drive line, thereby reducing the risk of personnel being exposed to X-ray radiation.

[0046] Similarly, in the present application, the first magnetic drive circulating line 1 includes a stator mechanism and a mover mechanism, wherein the mover mechanism corresponds to the mounting rack 102 in the present application, the mounting rack 102 is provided with a mounting position 1021 for mounting the first battery cell jig 7, and the stator mechanism corresponds to the track 101 in the present application. The mounting rack 102 on which the first battery cell jig 7 is mounted is slidably connected to the track 101, so that the battery cell placed on the first battery cell jig 7 can be quickly switched between different detection stations, thereby eliminating the frequent feeding and discharging actions of different detection stations, reducing the risk of appearance damage and introduction of foreign matters caused by multiple carrying of the battery cell, and at the same time, the spacing between two adjacent first battery cell jigs 7 can be flexibly adjusted according to needs.

[0047] Therefore, the battery cell is transported for detection by the first magnetic driving circulation line 1 and the second magnetic driving circulation line 8, which can greatly reduce the time of the battery cell in a single process operation, and the jig can reasonably avoid the positions of the rubber bonding and the CCD detection when the mover mechanism is switched to the position.

[0048] In some embodiments, referring to Figure 1 As shown, in order to improve the safety in the workshop, the radiation detection mechanism 5 needs to be subjected to corresponding radiation protection treatment, that is, part of the first magnetic driving circulation line 1 and the radiation detection mechanism 5 are arranged in the lead house 18, which can isolate the radiation emitted by the radiation detection mechanism 5 through the lead house 18. At the same time, the closed structure of the lead house 18 can prevent external interference to the radiation detection device 802, thereby improving the detection accuracy and ensuring the accuracy and consistency of the battery cell detection.

[0049] In some embodiments, referring to Figure 1 and Figure 3 As shown, the first magnetic driving circulation line 1 is provided with a weighing assembly 601, which is arranged downstream of the second magnetic driving circulation line 8 in the conveying direction of the first magnetic driving circulation line 1. The weighing assembly 601 includes a weighing base 6011, an electronic scale 6012, and a weighing frame 6013. The electronic scale 6012 is placed on the upper surface of the weighing base 6011, and the weighing frame 6013 is placed on the electronic scale 6012. The upper surface of the weighing frame 6013 is provided with a support position for supporting the battery cell. When weighing, the battery cell needs to be separated from the first battery cell jig 7 and placed on the support position. At this time, the value displayed by the electronic scale 6012 is the weight of the battery cell and the weighing frame 6013. The specific weight of the measured battery cell can be obtained by calculation. For example, the battery cell can also be transferred by a mechanical hand, that is, the mechanical hand separates the battery cell from the first battery cell jig 7 and transfers it to the support position.

[0050] In some embodiments, referring to Figure 1As shown, the discharging detection mechanism 6 includes a third conveying mechanism 605 and is provided with a bottom surface detection assembly, a thickness detection assembly and a discharging logistics line in sequence beside the weighing assembly 601. The third conveying mechanism 605 can convey the battery cell, so that the battery cell can pass through the bottom surface detection assembly, the thickness detection assembly and the discharging logistics line in sequence for detection. The weighing assembly 601 is used for weighing detection of the battery cell, to ensure that the weight of the battery cell is within a standard range. Abnormal weight of the battery cell may indicate internal defects of the battery cell, too much or too little adhesive material and the like. The bottom surface detection assembly 602 checks the bottom surface of the battery cell. Bottom surface detection usually includes checking whether the surface is flat, whether there are scratches or contamination and the like, to ensure that the bottom of the battery cell meets the appearance and structure requirements. The thickness detection assembly 603 is used for measuring the overall thickness of the battery cell, to ensure that the battery cell does not have thickness deviation in the adhesive and other processing procedures. Thickness deviation may affect the assembly and performance of the battery cell, and therefore the thickness detection assembly 603 can help ensure the consistency of the size of the battery cell. The discharging logistics line 604 is used for conveying the battery cell that passes the detection, and conveying it to the next production procedure. The discharging logistics line 604 can be provided with multiple lines. The multiple discharging logistics lines 604 are used for conveying different types of battery cells, to facilitate classification and conveying of different types of battery cells, to prepare for subsequent production procedures.

[0051] In some embodiments, after the X-ray detection of the battery cell by the X-ray detection device 802, the battery cell on the second battery cell jig 803 is conveyed to the first battery cell jig 7 by the first conveying mechanism 801 located downstream, and then the first battery cell jig 7 carrying the battery cell is conveyed to the weighing assembly 601 by the first magnetic drive circulation line 1, and the battery cell is subjected to weighing detection. The battery cell after the weighing detection can be conveyed to the bottom surface detection assembly 602 and the thickness detection assembly 603 in sequence by the conveying of the third conveying mechanism 605. After the battery cell passes through the bottom surface detection and the thickness detection, the battery cell that passes the detection is conveyed to the downstream procedure or the storage position by the discharging logistics line 604.

[0052] In some embodiments, with reference to Figures 4 to 9As shown, the first magnetic drive circulating line 1 comprises a track 101 and a plurality of mounting racks 102, each of which is slidingly connected to the track 101 and is provided with a mounting position 1021 for mounting the first battery cell jig 7. Meanwhile, the first battery cell jig 7 comprises a fixed bearing plate 701 and a connecting plate 702, which are connected by a first sliding assembly 703 between the connecting plate 702 and the mounting position 1021. The first sliding assembly 703 allows the first battery cell jig 7 to be movably connected to the mounting rack 102. The bearing plate 701 is provided with a bearing position 7011 for placing a battery cell, and the bearing position 7011 is provided with a through slot 7012 for the weighing rack 6013 to pass through. Therefore, when the battery cell needs to be weighed, the first sliding assembly 703 can be used to lower the height of the first battery cell jig 7, so that the weighing rack 6013 extends to the upper surface of the bearing plate 701 through the through slot 7012 and lifts the battery cell placed on the first battery cell jig 7. After the battery cell is completely separated from the first battery cell jig 7, the value displayed on the electronic scale 6012 can be read.

[0053] Also, referring to Figure 6 and Figure 7 As shown, the mounting position 1021 of the mounting rack 102 is fixedly connected with an abutting plate 1022, and the abutting plate 1022 is fixedly connected with a connecting rod 1024 for sleeving a buffer spring 1023 at one end away from the mounting rack 102. The other end of the buffer spring 1023 away from the abutting plate 1022 abuts against the connecting plate 702. The connecting rod 1024 can provide good guidance for the buffer spring 1023, ensuring that the buffer spring 1023 does not bend significantly, and providing good elastic support for the first battery cell jig 7, so that the buffer spring 1023 can lock the position of the first battery cell jig 7. That is, the buffer spring 1023 can effectively prevent the first battery cell jig 7 from continuously moving downward under the action of the first sliding assembly 703 when the first battery cell jig 7 is not subjected to external force. When the battery cell needs to be weighed, the first battery cell jig 7 can be pressed downward or pulled downward by external force, so that the first battery cell jig 7 moves downward relative to the first magnetic drive circulating line 1, so that the weighing rack 6013 can pass through the through slot 7012 and lift the battery cell on the bearing position 7011. When the weighing is finished, the downward pressing or pulling of the first battery cell jig 7 is cancelled. At this time, the buffer spring 1023 can also function as a reset. The compressed buffer spring 1023 gradually expands, lifts the first battery cell jig 7 upward, and restores the height of the position of the first battery cell jig 7 to the height before the external force is applied.

[0054] In some embodiments, referring to Figure 3 and Figure 8As shown, the first battery cell jig 7 can be driven to move along the height direction of the weighing base 6011 by a driving assembly, wherein the driving assembly comprises a driving cylinder 10, a first baffle 1001 is arranged on the output rod of the driving cylinder 10, a second baffle 7021 matched with the first baffle 1001 is arranged on the connecting plate 702, and the driving cylinder 10 can drive the first baffle 1001 to descend from the first position to the second position by driving the output rod, so that the first baffle 1001 abuts against the second baffle 7021 and drives the first battery cell jig 7 to descend; when the first baffle 1001 is located at the first position, the first baffle 1001 and the second baffle 7021 have a gap in the height direction, that is, when the first battery cell jig 7 moves to the weighing position of the weighing assembly 601, the first baffle 1001 at this time is located at the first position, the output rod of the driving cylinder 10 is in an extended state, so that the first baffle 1001 and the second baffle 7021 have a gap in the height direction; when weighing is needed, the output rod of the driving cylinder 10 is gradually retracted, so that the lower surface of the first baffle 1001 abuts against the upper surface of the second baffle 7021, at this time, the first baffle 1001 descends from the first position to the second position, that is, the first battery cell jig 7 moves downward compared with the position of the first magnetic driving circulating line 1, at this time, as the output rod of the driving cylinder 10 is continuously retracted, the position height of the bearing plate 701 is continuously lowered, so that the weighing frame 6013 passes through the through slot 7012 and lifts the battery cell, and after the battery cell is lifted, the weighing can be performed.

[0055] In some embodiments, reference is made to Figures 3 to 9As shown, in order to enable the battery cell to be placed in the first battery cell fixture 7 more stably, the battery cell can be clamped by a clamping mechanism, wherein the clamping mechanism comprises two clamping assemblies 9 arranged opposite along the length direction of the bearing plate 701, wherein the clamping assembly 9 comprises a first guide plate 901, a guide block 902, a second guide plate 903, a second sliding assembly 904, a third sliding assembly 905, a clamping block 906, and a guide rod 907, the clamping block 906 is slidably connected to the bearing plate 701 along a first direction through the third sliding assembly 905, the second guide plate 903 is slidably connected to the lower surface of the bearing plate 701 along a second direction through the second sliding assembly 904, the lower surface of the clamping block 906 is fixedly connected with the guide rod 907, and the bearing plate 701 is provided with a through hole for the guide rod 907 to pass through, the second guide plate 903 is provided with a guide hole 9031 for the guide rod 907 to pass through, one end of the second guide plate 903 away from the guide hole 9031 is fixedly connected with the guide block 902, the guide hole 9031 is strip-shaped and extends in a direction intersecting the first direction and the second direction, and the mounting position 1021 is fixedly connected with the first guide plate 901, and the first guide plate 901 is provided with a guide inclined surface 9011, and the guide block 902 is provided with a guide wheel 902 corresponding to the guide inclined surface 9011, when the driving assembly drives the bearing plate 701 to descend, the guide wheel 902 moves along the surface of the guide inclined surface 9011, so that the guide block 902 drives the second guide plate 903 to displace along the first direction, and then drives the clamping block 906 to displace along the second direction through the guide hole 9031.

[0056] For the convenience of understanding, reference will be made to the accompanying drawings Figure 5 As shown, the first direction can be the length direction of the bearing plate 701, and the second direction can be the width direction of the bearing plate 701.

[0057] Therefore, when the weighing detection is needed, the driving assembly drives the first battery cell fixture 7 to move along the height direction of the weighing base 6011, that is, the first battery cell fixture 7 moves downward relative to the first magnetic drive circulating line 1, and because the first guide plate 901 is fixedly connected to the mounting position 1021 of the mounting frame 102, the first guide plate 901 is not affected by the driving assembly, at this time, as the first battery cell fixture 7 continuously moves downward, the guide wheel 9021 on the guide block 902 contacts the guide inclined surface 9011 provided on the first guide plate 901, and under the guidance of the guide inclined surface 9011, the guide block 902 and the second guide plate 903 move toward the first magnetic drive circulating line 1, as shown in Figure 5 As shown, the first direction can be the length direction of the bearing plate 701, and the second direction can be the width direction of the bearing plate 701.

[0057] Therefore, when the weighing detection is needed, the driving assembly drives the first battery cell fixture 7 to move along the height direction of the weighing base 6011, that is, the first battery cell fixture 7 moves downward relative to the first magnetic drive circulating line 1, and because the first guide plate 901 is fixedly connected to the mounting position 1021 of the mounting frame 102, the first guide plate 901 is not affected by the driving assembly, at this time, as the first battery cell fixture 7 continuously moves downward, the guide wheel 9021 on the guide block 902 contacts the guide inclined surface 9011 provided on the first guide plate 901, and under the guidance of the guide inclined surface 9011, the guide block 902 and the second guide plate 903 move toward the first magnetic drive circulating line 1, as shown in Figure 9As shown, in order to enable the guide hole 9031 to drive the guide rod 907 to move, the guide hole 9031 is configured as a strip-shaped inclined hole to move, so that the guide rod 907 drives the clamping block 906 to move away from the direction of the battery, thereby enabling the two oppositely arranged clamping blocks 906 to no longer clamp the battery. At the same time that the clamping block 906 no longer clamps the battery, the weighing frame 6013 lifts the battery through the through slot 7012, and then the battery is weighed by the electronic scale 6012.

[0058] In some embodiments, referring to Figure 7 and Figure 8 As shown, the first sliding assembly 703, the second sliding assembly 904, and the third sliding assembly 905 are all configured as a slide rail and a slide block, wherein the first sliding assembly 703 enables the first battery jig 7 to be smoothly and smoothly connected to the mounting frame 102; the second sliding assembly 904 enables the second guide plate 903 to be smoothly and smoothly connected to the lower surface of the bearing plate 701; and the third sliding assembly 905 enables the clamping block 906 to be smoothly and smoothly connected to the upper surface of the bearing plate 701.

[0059] In some embodiments, referring to Figures 4 to 9 As shown, a reset push rod 11 for abutting and limiting the movement of the second guide plate 903 is also provided. When the second guide plate 903 reciprocates, the guide hole 9031 on the second guide plate 903 can drive the guide rod 907 to move, so that the clamping block 906 fixedly connected to the guide rod 907 abuts or releases the battery. Therefore, when the first battery jig 7 carrying the battery moves in the conveying direction of the first magnetic drive circulation line 1 to perform various detections, the reset push rod 11 abutting the second guide plate 903 can abut the second guide plate 903 to limit the movement of the second guide plate 903, so that the clamping block 906 can firmly clamp and fix the battery.

[0060] In some embodiments, referring to Figure 4 and Figure 5 As shown, the bearing plate 701 is provided with a gasket 12 for supporting the battery, and the gasket 12 is arranged around the outside of the through slot 7012. The gasket 12 can be made of soft, wear-resistant and elastic materials such as rubber and silicone. The gasket 12 can buffer the direct contact between the battery and the bearing plate 701, and reduce damage caused by friction or pressure.

[0061] In some embodiments, referring to Figure 4 and Figure 5As shown, the carrier plate 701 is further provided with limiting blocks 13 for limiting the position of the battery cell. The limiting blocks 13 are arranged opposite to each other along the width direction of the carrier plate 701. The position of the battery cell on the carrier plate 701 is limited by the at least two limiting blocks 13 arranged opposite to each other, so as to prevent the battery cell from being displaced during the carrying or detection process. The limiting blocks 13 can ensure the relative position of the battery cell to be fixed, so as to provide accurate positioning for the detection to be performed.

[0062] Meanwhile, when the battery cell is placed on the carrying position of the carrier plate 701, the limiting blocks 13 can limit the battery cell from the width direction of the carrier plate 701, and the clamping assembly can clamp and fix the battery cell from the length direction of the carrier plate 701.

[0063] In some embodiments, referring to Figure 4 and Figure 5 As shown, the tab is an important component of the battery cell for connecting the circuit, and needs to be properly protected during the carrying and detection process. Therefore, the carrier plate 701 is further provided with a support block 14 for supporting the tab of the battery cell. The support block 14 can provide stable support for the tab, so as to prevent the tab from being bent, broken or damaged in other forms during the detection and carrying of the battery cell.

[0064] In some embodiments, referring to Figure 1 As shown, when the battery cell placed in the first battery cell jig 7 passes through the CCD detection mechanism 4, the ray detection mechanism 5 and the unloading detection mechanism 6 in sequence along the conveying direction of the first magnetic drive circulation line 1, there are battery cells that fail to pass the detection. Therefore, the unqualified battery cells are stored by the storage bin 15. The storage bin 15 is provided with a storage position 17 between the thickness detection assembly 603 and the unloading logistics line 604 for placing the battery cells that fail to pass the detection. The unqualified battery cells can be carried to the storage position 17 by the third carrying mechanism 605, and then the fourth carrying mechanism 16 located between the storage bin 15 and the storage position 17 carries the unqualified battery cells from the storage position 17 to the storage bin 15.

[0065] In some embodiments, referring to Figure 1 As shown, the unloading detection mechanism 2 includes an unloading logistics line 201, a second carrying mechanism 202 and a code scanner. The unloading logistics line 201 is used to transport the battery cells. The code scanner is used to scan the code of the battery cells transported by the unloading logistics line 201. The second carrying mechanism 202 is arranged between the storage bin 15 and the first magnetic drive circulation line 1, and is used to carry the qualified battery cells scanned to the first battery cell jig 7, and / or carry the unqualified battery cells scanned to the storage bin 15.

[0066] Exemplarily, the code scanner can be arranged on the second carrying mechanism 202, and the code scanner can scan the code on the battery cell during the carrying of the battery cell by the second carrying mechanism 202.

[0067] Exemplarily, the code scanner can be arranged on the feeding logistics line 201, and after the battery cell is scanned by the code scanner during the conveying of the battery cell, it is determined whether the battery cell is a qualified battery cell; when the battery cell scanned by the code scanner is a unqualified product, the second carrying mechanism 202 carries the unqualified battery cell to the storage bin 15 for storage, and when the unqualified battery cells stored in the storage bin 15 accumulate to a certain amount, the unqualified battery cells are uniformly returned to the factory for repair, which helps to reduce the number of returns to the factory for repair and improve the processing efficiency; the qualified battery cell scanned by the code scanner is carried to the first battery cell fixture 7 by the second carrying mechanism 202, and then the battery cell is subjected to subsequent related detection.

[0068] In some embodiments, the first carrying mechanism 801, the second carrying mechanism 202, the third carrying mechanism 605 and the fourth carrying mechanism 16 can all be selected from a mechanical hand, so as to realize the carrying of the battery cell, or a linear module with a clamping jaw.
