Description
技术领域Technical Field
本发明涉及锂电池检测技术领域,具体为一种精密锂电池漏液检测设备。The present invention relates to the technical field of lithium battery detection, in particular to a precision lithium battery leakage detection device.
背景技术Background Art
锂电池加工具有多道工序,在工序流转中难免对电池造成一定程度的损伤,当电池铝膜破损则必须报废,为了区别锂电池是否破损,目前采用的是负压检测方法,其基本原理是利用电芯正反面各4个吸盘贴住电芯,在一个密闭腔室内对吸盘内抽负压,当无破损时,电芯与吸盘接触得部分不会发生形变或者变化,当有破损时,腔室内的空气与电芯内连通,此时吸盘内外形成压力差,铝膜变形形成鼓泡,后由人工辨别选出。Lithium battery processing involves multiple steps, and it is inevitable that the battery will be damaged to a certain extent during the process flow. When the aluminum film of the battery is damaged, it must be scrapped. In order to distinguish whether the lithium battery is damaged, the negative pressure detection method is currently used. The basic principle is to use 4 suction cups on the front and back of the battery cell to stick to the battery cell, and draw negative pressure into the suction cup in a closed chamber. When there is no damage, the part of the battery cell that contacts the suction cup will not deform or change. When there is damage, the air in the chamber is connected to the battery cell. At this time, a pressure difference is formed inside and outside the suction cup, and the aluminum film is deformed to form bubbles, which are then manually identified and selected.
然而这种接触式的检测方式在工作时由于模腔内压力和电池表面之间的压力差值比较大,所以电池表面容易产生吸盘印,换型比较麻烦,兼容性比较小;又例如现有中国专利文献CN201711372002.3公开了一种基于机器视觉的锂电池缺陷检测方法,其通过图像分析检测锂电池侧边是否在破损,漏液,封膜切边不良等状况,将检测结果实时反馈给工控机,最后挑出不合格的锂电池,但是该专利中的检测方法只针对锂电池侧边是否漏液破损进行检测,对于方形的精密锂电池而言由于其具有六个面,在六个面的位置均有可能因为工艺的原因产生破损漏液的情况,所以无论是接触式的检测还是非接触式的检测均无法达到对精密锂电池的全方位检测,还是存在着检测效率低,漏检率高的问题。However, this contact detection method is prone to suction cup marks on the battery surface due to the large pressure difference between the pressure in the mold cavity and the battery surface during operation. It is troublesome to change the model and has low compatibility. For example, the existing Chinese patent document CN201711372002.3 discloses a lithium battery defect detection method based on machine vision, which detects whether the side of the lithium battery is damaged, leaking, or has poor sealing film cutting through image analysis, and feeds back the detection results to the industrial computer in real time, and finally selects unqualified lithium batteries. However, the detection method in this patent only detects whether the side of the lithium battery is leaking or damaged. For square precision lithium batteries, since they have six sides, damage and leakage may occur on all six sides due to process reasons. Therefore, neither contact detection nor non-contact detection can achieve all-round detection of precision lithium batteries, and there are still problems of low detection efficiency and high missed detection rate.

The figure shows a precision lithium battery leakage detection device, including a feed conveyor 1, a support frame 2 and a discharge conveyor 3. The feed conveyor 1 is fixedly connected to a hollow circular shell 4 through the support frame 2, and the discharge conveyor 3 is located on one side of the hollow circular shell 4. The lithium batteries to be detected are conveyed one by one by the feed conveyor 1, and after the detection, they are conveyed from the discharge conveyor 3 to the next workstation; it also includes: a turning mechanism 5 installed inside the hollow circular shell 4, the upper end of the hollow circular shell 4 is in an open state, and upper and lower surface detection mechanisms 6 are installed on both sides of the open position of the upper end of the hollow circular shell 4, a first arc-shaped transition plate 7 is provided between the feed conveyor 1 and the turning mechanism 5, and a side detection mechanism 8 is provided between the turning mechanism 5 and the discharge conveyor 3. The lithium batteries are conveyed from the feed conveyor 1 to the first The lithium battery is placed on the arc-shaped transition plate 7 and enters the material receiving end of one side of the flipping mechanism 5. The flipping mechanism 5 adjusts the upper and lower sides of the lithium battery, and uses the upper and lower surface detection mechanisms 6 to detect the front and back sides of the lithium battery respectively. Finally, the side detection mechanism 8 can automatically adjust and detect several surfaces except the upper and lower surfaces, and then use image analysis to detect whether each surface of the lithium battery is damaged or leaking, so as to achieve all-round detection of precision lithium batteries with high detection efficiency and low missed detection rate; a transmission mechanism 9 is installed on the outside of the hollow circular shell 4, and the input end of the transmission mechanism 9 is connected to the feed conveyor 1, and its output end is connected to the flipping mechanism 5. The designed transmission mechanism 9 can realize the linkage between the feed conveyor 1 and the flipping mechanism, so as to facilitate the flipping mechanism to rotate at equal angles as the feed conveyor 1 rotates.
进一步的,参阅图1和图3,为了可以自动对锂电池的上下检测面进行翻转,翻面机构5包括转动连接在空心圆壳4中部两侧的转轴10,两个转轴10之间固定有转动块11,转动块11呈正六边形,转动块11的每个侧面均固定有一块接料壳12,接料壳12的上下侧均设有凹槽,传动机构9的输出端与其中一个转轴10传动连接。Further, referring to Figures 1 and 3, in order to automatically flip the upper and lower detection surfaces of the lithium battery, the flipping mechanism 5 includes a rotating shaft 10 rotatably connected to both sides of the middle of the hollow circular shell 4, and a rotating block 11 is fixed between the two rotating shafts 10. The rotating block 11 is a regular hexagon, and a material receiving shell 12 is fixed on each side of the rotating block 11. The upper and lower sides of the material receiving shell 12 are provided with grooves, and the output end of the transmission mechanism 9 is transmission-connected to one of the rotating shafts 10.
对锂电池进行翻面的原理:落入到第一弧形过渡板7上的锂电池经过短暂的运动会先落入到与之靠近的其中一个接料壳12上,然后进料输送机1继续运转通过传动机构9带动转轴10转动,转轴10带动转动块11转动,转动块11带动接料壳12先转动六十度,此时锂电池滑动至最下方位置并在重力的作用下会自动调转方向并倒向相邻的接料壳12上,从而完成自动翻面的动作,而此时下一个锂电池刚好滑入到其中一个接料壳12上,再通过上述步骤进行自动翻面。The principle of turning over the lithium battery: the lithium battery that falls on the first arc-shaped transition plate 7 will fall onto one of the receiving shells 12 close to it after a short movement, and then the feed conveyor 1 continues to operate and drives the rotating shaft 10 to rotate through the transmission mechanism 9, and the rotating shaft 10 drives the rotating block 11 to rotate, and the rotating block 11 drives the receiving shell 12 to rotate sixty degrees first. At this time, the lithium battery slides to the lowermost position and will automatically turn around and fall onto the adjacent receiving shell 12 under the action of gravity, thereby completing the automatic turning over action. At this time, the next lithium battery just slides into one of the receiving shells 12, and then automatically turns over through the above steps.
进一步的,参阅图4,为了可以分别对锂电池的上下侧进行逐步检测,上下面检测机构6包括第一安装板13、U型连接板14和第一工业相机15,第一安装板13的两侧均通过U型连接板14固定在空心圆壳4的顶部,第一工业相机15固定在第一安装板13的中部且其检测端正对着空心圆壳4的内部。Further, referring to Figure 4, in order to be able to gradually detect the upper and lower sides of the lithium battery respectively, the upper and lower detection mechanism 6 includes a first mounting plate 13, a U-shaped connecting plate 14 and a first industrial camera 15. Both sides of the first mounting plate 13 are fixed to the top of the hollow circular shell 4 through the U-shaped connecting plate 14. The first industrial camera 15 is fixed in the middle of the first mounting plate 13 and its detection end faces the interior of the hollow circular shell 4.
对锂电池的上下面进行分别检测的原理:首先从第一弧形过渡板7滑入到接料壳12上的锂电池会先通过上方的第一工业相机15进行拍照检测,若检测合格则控制机不报警,并且继续对进料输送机1进行运转,进料输送机1通过传动机构9带动翻面机构5对锂电池进行翻面,并在转轴10转动一百二十度后自动将锂电池输送至下一组第一工业相机15的正下方并对其进行检测,检测好以后转轴10再转动六十度,将锂电池输送至侧面检测机构8的位置处进行下一步的检测。The principle of separately inspecting the upper and lower surfaces of the lithium battery is as follows: first, the lithium battery that slides from the first arc-shaped transition plate 7 to the receiving shell 12 will first be photographed and inspected by the first industrial camera 15 above. If the inspection is qualified, the control machine will not alarm and continue to operate the feed conveyor 1. The feed conveyor 1 drives the turning mechanism 5 to turn the lithium battery over through the transmission mechanism 9, and after the shaft 10 rotates one hundred and twenty degrees, the lithium battery is automatically transported to the bottom of the next group of first industrial cameras 15 and inspected. After the inspection, the shaft 10 rotates another sixty degrees to transport the lithium battery to the position of the side inspection mechanism 8 for the next step of inspection.
进一步的,请参阅图5和图6,图示中的侧面检测机构8包括第二安装板16、第二工业相机17、推动件18、承接件19和第二弧形过渡板20,第二安装板16固定在空心圆壳4的外侧壁,第二工业相机17固定在第二安装板16的一端且其检测端正对着承接件19的方向,第二安装板16的一侧安装有用于将检测好的锂电池进行自动卸料的推动件18,承接件19固定在空心圆壳4的底部,且其用于接住待检测的锂电池,第二弧形过渡板20的两端与空心圆壳4的内壁固定,设计的侧面检测机构8可以对除了上下面的几个面进行自动调整检测;Further, please refer to Figures 5 and 6.

The second mounting plate 16 is fixed to the outer wall of the hollow circular shell 4. The second industrial camera 17 is fixed to one end of the second mounting plate 16 and its detection end faces the receiving member 19. A pusher 18 for automatically unloading the detected lithium batteries is installed on one side of the second mounting plate 16. The receiving member 19 is fixed to the bottom of the hollow circular shell 4 and is used to receive the lithium batteries to be detected. The two ends of the second arc-shaped transition plate 20 are fixed to the inner wall of the hollow circular shell 4. The designed side detection mechanism 8 can automatically adjust and detect several surfaces except the upper and lower surfaces;
其中,为了便于对锂电池进行顺利接收,承接件19包括第三安装板21、步进电机22、空心圆筒23、第一气缸24、限位台25和接料板26,第三安装板21固定在空心圆壳4的底部,步进电机22固定在第三安装板21上,步进电机22的输出端通过联动器固定有连接轴27,连接轴27固定在空心圆筒23的底部,第一气缸24安装在空心圆筒23的内部,空心圆筒23的顶部为敞开状态,空心圆筒23的顶端固定在限位台25的底部,且在限位台25的底部与空心圆筒23内部相连通,第一气缸24的输出端与接料板26的底部固定连接,接料板26上开设有凹槽,初始状态时接料板26位于凹槽内,第二弧形过渡板20的下端位于限位台25的斜上方。Among them, in order to facilitate the smooth reception of the lithium battery, the receiving part 19 includes a third mounting plate 21, a stepper motor 22, a hollow cylinder 23, a first cylinder 24, a limit platform 25 and a receiving plate 26. The third mounting plate 21 is fixed to the bottom of the hollow shell 4, the stepper motor 22 is fixed on the third mounting plate 21, and the output end of the stepper motor 22 is fixed with a connecting shaft 27 through a linkage, and the connecting shaft 27 is fixed to the bottom of the hollow cylinder 23. The first cylinder 24 is installed inside the hollow cylinder 23, and the top of the hollow cylinder 23 is in an open state. The top of the hollow cylinder 23 is fixed to the bottom of the limit platform 25, and is connected to the inside of the hollow cylinder 23 at the bottom of the limit platform 25. The output end of the first cylinder 24 is fixedly connected to the bottom of the receiving plate 26, and a groove is provided on the receiving plate 26. In the initial state, the receiving plate 26 is located in the groove, and the lower end of the second arc-shaped transition plate 20 is located obliquely above the limit platform 25.
另外,为了可以将检测好的锂电池进行自动卸料,推动件18包括第四安装板28、第二气缸29和推板30,第四安装板28固定在第二安装板16的一侧,第二气缸29嵌入安装于第四安装板28的中部,第二气缸29的输出端固定有推板30,推板30位于限位台25的顶部上方。In addition, in order to automatically unload the inspected lithium batteries, the pushing member 18 includes a fourth mounting plate 28, a second cylinder 29 and a push plate 30. The fourth mounting plate 28 is fixed on one side of the second mounting plate 16, and the second cylinder 29 is embedded in the middle of the fourth mounting plate 28. The output end of the second cylinder 29 is fixed with a push plate 30, and the push plate 30 is located above the top of the limit platform 25.
具体来说,锂电池通过第二弧形过渡板20滑入到限位台25上,并且恰好落到接料板26的顶部,然后第一气缸24启动,并带动接料板26和锂电池上升至与第二工业相机17相平齐的位置,然后步进电机22依次输入四个旋转九十度的脉冲电流,从而带动锂电池的四个侧面分别对着第二工业相机17,第二工业相机17对四个侧面进行逐面检测,检测合格以后再启动第二气缸29工作,第二气缸29带动推板30往前迅速运动,从而推动锂电池平抛运动并落在出料输送机3上,然后第一气缸24、和第二气缸29均自动回位,等待下一个锂电池落入到限位台25上,并再次按照上述步骤进行检测。Specifically, the lithium battery slides onto the limit platform 25 through the second arc-shaped transition plate 20 and falls exactly on the top of the receiving plate 26. Then the first cylinder 24 is started and drives the receiving plate 26 and the lithium battery to rise to a position flush with the second industrial camera 17. Then the stepper motor 22 sequentially inputs four pulse currents rotated ninety degrees, thereby driving the four sides of the lithium battery to face the second industrial camera 17 respectively. The second industrial camera 17 performs surface inspection on the four sides. After the inspection is qualified, the second cylinder 29 is started again. The second cylinder 29 drives the push plate 30 to move forward rapidly, thereby pushing the lithium battery to move horizontally and fall on the discharge conveyor 3. Then the first cylinder 24 and the second cylinder 29 automatically return to their positions, waiting for the next lithium battery to fall onto the limit platform 25, and then perform inspection again according to the above steps.
进一步的,参阅图7,第一弧形过渡板7的上端与进料输送机1的右端之间呈不接触设置,第一弧形过渡板7的下端延伸至空心圆壳4的内部且其两侧均与空心圆壳4的内壁固定,锂电池从进料输送机1的出料端滑入到第一弧形过渡板7上,由于第一弧形过渡板7的上端与进料输送机1的右端之间不接触,所以能够保证锂电池能够顺利地进入到翻面机构5的接料壳12上。Further, referring to Figure 7, the upper end of the first arc-shaped transition plate 7 is non-contacting with the right end of the feed conveyor 1, the lower end of the first arc-shaped transition plate 7 extends to the interior of the hollow circular shell 4 and both sides are fixed to the inner wall of the hollow circular shell 4, and the lithium battery slides from the discharge end of the feed conveyor 1 onto the first arc-shaped transition plate 7. Since there is no contact between the upper end of the first arc-shaped transition plate 7 and the right end of the feed conveyor 1, it can ensure that the lithium battery can smoothly enter the receiving shell 12 of the flipping mechanism 5.
本方案,对锂电池进行批量逐面检测的流程;This solution is a process for batch inspection of lithium batteries.
首先,第一个锂电池会随着进料输送机1的运转运输到出料端位置,此时会有一个接料壳12恰好和第一弧形过渡板7的底端进行衔接,从而让第一个锂电池自动滑入到此处的接料框内,然后进料输送机1再运转一圈,并带动传动机构9运转,与传动机构9传动连接的转轴10会随之转动六分之一圈,初始位置处的接料壳12转动六十度,该处的锂电池滑动至最下方位置并在重力的作用下自动调转方向并倒向相邻的接料壳12上,而此时恰好下一个接料壳12替代上一个接料壳12的位置,并且也会滑入下一块锂电池;First, the first lithium battery will be transported to the discharge end position with the operation of the feed conveyor 1. At this time, a receiving shell 12 will be connected with the bottom end of the first arc-shaped transition plate 7, so that the first lithium battery will automatically slide into the receiving frame here, and then the feed conveyor 1 will rotate one more circle, and drive the transmission mechanism 9 to operate. The rotating shaft 10 connected to the transmission mechanism 9 will rotate one-sixth of a circle, and the receiving shell 12 at the initial position will rotate sixty degrees. The lithium battery at this position slides to the lowest position and automatically turns around under the action of gravity and falls onto the adjacent receiving shell 12. At this time, the next receiving shell 12 will replace the position of the previous receiving shell 12, and the next lithium battery will also slide in.
之后,进料输送机1再运转一圈,并带动传动机构9运转,与传动机构9传动连接的转轴10会随之转动六分之一圈,此时翻面好的锂电池会刚好转动至水平位置,此时该处的锂电池正上方的第一工业相机15自动工作对其进行拍照检测,而下一块锂电池也刚好完成翻面动作,第一块锂电池检测好以后转轴10再转动六十度,第一块锂电池通过第二弧形过渡板20进入到限位台25上,并且恰好落到接料板26的顶部,然后第一气缸24启动,并带动接料板26和锂电池上升至与第二工业相机17相平齐的位置,然后步进电机22依次输入四个旋转九十度的脉冲电流,从而带动锂电池的四个侧面分别对着第二工业相机17,第二工业相机17对四个侧面进行逐面检测,检测合格以后再启动第二气缸29工作,第二气缸29带动推板30往前迅速运动,从而推动锂电池平抛运动并落在出料输送机3上,然后第一气缸24、和第二气缸29均自动回位,等待下一个锂电池落入到限位台25上,并再次按照上述步骤进行检测;After that, the feeding conveyor 1 rotates one more circle and drives the transmission mechanism 9 to operate. The rotating shaft 10 connected to the transmission mechanism 9 will rotate one-sixth of a circle. At this time, the flipped lithium battery will just rotate to a horizontal position. At this time, the first industrial camera 15 directly above the lithium battery will automatically work to take a photo and detect it, and the next lithium battery will just complete the flipping action. After the first lithium battery is detected, the rotating shaft 10 will rotate another sixty degrees. The first lithium battery passes through the second arc transition plate 20 and enters the limit table 25, and just falls on the top of the receiving plate 26. Then the first cylinder 24 starts and drives the receiving plate 26. The lithium battery rises to a position flush with the second industrial camera 17, and then the stepper motor 22 sequentially inputs four pulse currents rotating ninety degrees, thereby driving the four sides of the lithium battery to face the second industrial camera 17 respectively. The second industrial camera 17 detects the four sides one by one. After the detection is qualified, the second cylinder 29 is started to work, and the second cylinder 29 drives the push plate 30 to move forward quickly, thereby pushing the lithium battery to move horizontally and fall on the discharge conveyor 3, and then the first cylinder 24 and the second cylinder 29 are automatically returned to their positions, waiting for the next lithium battery to fall onto the limit table 25, and then the detection is performed again according to the above steps;
综上,按照上述步骤可以通过图像分析的方式检测锂电池各个面是否破损漏液,达到对精密锂电池的全方位检测,并且采用逐个输送锂电池的方式进行检测,实现流水线式输送锂电池,能够对锂电池进行批量检测,提高对锂电池的检测效率。In summary, according to the above steps, image analysis can be used to detect whether the various surfaces of the lithium battery are damaged or leaking, thereby achieving all-round detection of precision lithium batteries, and the detection is carried out by conveying lithium batteries one by one, realizing assembly line conveying of lithium batteries, and being able to perform batch detection of lithium batteries, thereby improving the detection efficiency of lithium batteries.
实施例二:请参阅图7,本实施方式对于实施例一进一步说明,其区别点在于实现翻面动作进行优化。Embodiment 2: Please refer to FIG. 7 . This embodiment further illustrates Embodiment 1, and the difference lies in that the turning action is optimized.
具体的,传动机构9包括与进料输送机1一端固定连接的主动带轮31,主动带轮31通过同步带传动连接有从动带轮32,从动带轮32的中孔内固定有第一传动轴33,第一传动轴33的一端通过轴承与空心圆壳4的外壁转动连接,传动轴的外侧还固定套接有不完全齿轮34,不完全齿轮34的一侧设有转向齿轮35,转向齿轮35的中孔内固定有第二传动轴36,第二传动轴36的一端通过轴承与空心圆壳4的外壁转动连接,转向齿轮35的一侧啮合有驱动齿轮37,驱动齿轮37固定套接在其中一个转轴10的外侧,设计的传动机构9可以实现进料输送机1和翻转机构之间的联动。Specifically, the transmission mechanism 9 includes a driving pulley 31 fixedly connected to one end of the feed conveyor 1, the driving pulley 31 is connected to a driven pulley 32 through a synchronous belt drive, a first transmission shaft 33 is fixed in the center hole of the driven pulley 32, one end of the first transmission shaft 33 is rotatably connected to the outer wall of the hollow circular shell 4 through a bearing, an incomplete gear 34 is fixedly sleeved on the outer side of the transmission shaft, a steering gear 35 is provided on one side of the incomplete gear 34, a second transmission shaft 36 is fixed in the center hole of the steering gear 35, one end of the second transmission shaft 36 is rotatably connected to the outer wall of the hollow circular shell 4 through a bearing, a driving gear 37 is meshed on one side of the steering gear 35, and the driving gear 37 is fixedly sleeved on the outside of one of the rotating shafts 10. The designed transmission mechanism 9 can realize the linkage between the feed conveyor 1 and the flipping mechanism.
对转轴10进行间歇转动的原理:由进料输送机1的输出端带动主动带轮31转动,主动带轮31和进料输送机1的转动角度相同且都会转动一圈,然后通过同步带带动从带轮也转动一圈,此时第一传动轴33也转动一圈并带动不完全齿轮34转动一圈,由于不完全齿轮34上设有部分齿牙,所以齿牙与转向齿轮35啮合时会带动其转动小于一圈,并且第二传动轴36和第一传动轴33的旋转方向相反,而转向齿轮35会刚好带动驱动齿轮37转动六十度,并且让驱动齿轮37和不完全齿轮34的旋转方向相同。The principle of intermittent rotation of the rotating shaft 10 is as follows: the output end of the feed conveyor 1 drives the active pulley 31 to rotate, the rotation angles of the active pulley 31 and the feed conveyor 1 are the same and both rotate one circle, and then the slave pulley is driven by the synchronous belt to rotate one circle. At this time, the first transmission shaft 33 also rotates one circle and drives the incomplete gear 34 to rotate one circle. Since the incomplete gear 34 is provided with partial teeth, the teeth will drive it to rotate less than one circle when it meshes with the steering gear 35, and the second transmission shaft 36 and the first transmission shaft 33 have opposite rotation directions, and the steering gear 35 will just drive the drive gear 37 to rotate sixty degrees, and make the drive gear 37 and the incomplete gear 34 rotate in the same direction.
实施例三:请参阅图3和图7,本实施方式对于其它实施例进一步说明,区别点在于对翻面动作进一步进行优化。Embodiment 3: Please refer to FIG. 3 and FIG. 7 . This embodiment further illustrates other embodiments, and the difference lies in that the turning action is further optimized.
具体的,翻面机构5包括转动连接在空心圆壳4中部两侧的转轴10,两个转轴10之间固定有转动块11,转动块11呈正六边形,转动块11的每个侧面均固定有一块接料壳12,接料壳12的上下侧均设有凹槽,传动机构9的输出端与其中一个转轴10传动连接,转动块11的两端均固定有环形挡板38,转动块11的外侧均匀分布有圆角,当锂电池下滑时会在环形挡板38的阻挡作用下不会滑离接料壳12,并且下滑至最下方时转动块11的圆角处理会有一个凸起阻挡的作用,使得锂电池在运动时更加稳定。Specifically, the flipping mechanism 5 includes a rotating shaft 10 rotatably connected to both sides of the middle part of the hollow circular shell 4, a rotating block 11 is fixed between the two rotating shafts 10, the rotating block 11 is in a regular hexagon, a material receiving shell 12 is fixed to each side of the rotating block 11, and grooves are provided on the upper and lower sides of the material receiving shell 12. The output end of the transmission mechanism 9 is transmission-connected to one of the rotating shafts 10, and annular baffles 38 are fixed at both ends of the rotating block 11. Rounded corners are evenly distributed on the outside of the rotating block 11. When the lithium battery slides down, it will not slide off the material receiving shell 12 under the blocking action of the annular baffle 38, and when it slides down to the bottom, the rounded corner treatment of the rotating block 11 will have a convex blocking effect, so that the lithium battery is more stable during movement.
