Has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as a solar cell. The performance parameters of the battery are mainly electromotive force, capacity, specific energy and resistance.

For the existing glue layer detection method, a pigment is usually added into a glue solution, the uniformity and the continuity of the glue layer are judged according to the color of a visual detection image in subsequent visual detection by depending on the color of the pigment.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
It should be noted that, a space ring is generally arranged inside the battery, and the space ring has the function of preventing water and improving the sealing performance of the battery. However, sealing by the spacer is unreliable, glue is coated on the two sides of the spacer in the actual production process of the battery, glue layers are formed on the two sides of the spacer, the sealing performance of the battery is improved by the spacer and the glue layers on the two sides of the spacer, and external foreign matters are prevented from entering the battery to damage the battery. It can be understood that the glue layer is crucial to the battery, the glue layer is an important guarantee for the sealing performance of the battery, and in the manufacturing process of the battery, in order to ensure the reliability of the glue layer, the glue layer of the battery is generally detected, that is, the uniformity and the continuity of the glue layer are detected, so as to prevent incomplete conditions from occurring inside the glue layer.
However, in the conventional adhesive layer detection method, a pigment is usually added to the adhesive solution, and the uniformity and continuity of the adhesive layer are determined according to the color of the visual detection image in the subsequent visual detection by depending on the color of the pigment. Firstly, because the thickness of the adhesive layer of the battery is thin and is generally only in millimeter level, when the adhesive layer is subjected to visual detection, the color presented by the final image pigment is not deep, namely the color presented by the pigment is not deep, so that a detector is difficult to accurately judge the uniformity and continuity of the adhesive layer of the battery, namely the detector is difficult to detect the adhesive layer of the battery; in addition, if the color of the glue layer is to be deepened, a large amount of pigment is required to be added into the glue solution, but the pigment comprises a large amount of noble metal ions, the sealing performance of the glue layer is affected by the addition of the pigment in a large amount, so that the sealing performance of the battery is reduced, meanwhile, the pigment is easy to settle, if the pigment settles, the uniformity and the continuity of the glue layer are affected when the space ring is coated, and the subsequent detection difficulty of the glue layer is also greatly improved; moreover, because the kind of space ring is various, different space ring self colour is just different, when the glue solution coating was on the space ring, if the colour of glue film was unanimous with the colour of space ring, the glue film on the space ring just very difficult was discerned and was detected to measurement personnel, also can increase the detection degree of difficulty and also can greatly increased equally.
Therefore, based on the above problems, the application discloses a battery gluing detection method, which can detect the glue layer of a battery, and has high detection accuracy and low misjudgment rate.
Referring to fig. 1, a method for detecting battery glue includes the following steps:
and step S01, adding a luminescent material into the glue solution to obtain the glue solution to be detected.
In this way, it should be noted that, a luminescent material is added to the glue solution that needs to be performed on the battery component to obtain a glue solution to be detected, and the glue solution to be detected can have a luminescent function under certain conditions.
And step S02, coating the glue solution to be detected on the battery component.
Therefore, it should be noted that after the to-be-detected glue solution with the light-emitting function is obtained, the to-be-detected glue solution is coated on the battery component, and after the glue solution is cured, a glue layer with the light-emitting capability is formed on the battery component, so that preparation is provided for subsequent visual detection.
Step S03, the battery component coated with the glue solution to be detected is placed in an environment capable of enabling the glue solution to be detected to emit light, and visual detection is carried out on the battery component coated with the glue solution to be detected.
Therefore, it should be noted that, after the glue solution to be detected is coated on the battery component, the glue solution to be detected of the battery component is cured to form a glue layer, at this time, the battery component coated with the glue solution to be detected is placed in an environment where the glue solution to be detected can emit light, because the glue solution to be detected has a light emitting function, when the battery component is subjected to visual detection imaging, the glue solution to be detected on the battery component is displayed very clearly on an image, namely, the glue layer can emit light, the image is very clear, a detector can very easily judge the uniformity and the continuity of the glue layer on the battery component according to the image, the detection accuracy is greatly improved, and the misjudgment rate is reduced.
It should be further noted that, in the present application, the glue solution to be detected is equal to the glue layer, the glue solution to be detected is in a liquid state of the glue layer, the glue layer is in a solid state of the glue solution to be detected, and detecting the glue layer is actually detecting the glue solution to be detected.
It should be further noted that, compared with adding a pigment to the glue solution for imaging, the method of the present application has the following advantages:
firstly, as the luminescent material is added into the glue solution, the luminescent material can present certain brightness in a luminescent environment, and can be obviously distinguished from the battery component, so that a detector can quickly identify the position of the glue layer, namely the glue layer with the luminescent function has high contrast with the battery component, and the detection efficiency of the detector is greatly improved;
secondly, due to the high contrast, excessive luminescent materials do not need to be added into the glue solution, so that after the glue solution to be detected is solidified to form the glue layer, the luminescent materials do not reduce the self-sealing performance of the glue layer, the sealing performance of the final battery can be well ensured, and compared with a method of excessively adding pigments, the method does not damage the sealing performance of the glue layer;
thirdly, although a small amount of luminescent material is added in the detection method, due to the luminescent function of the glue solution to be detected, the final imaged image is very clear, so that a detector can well detect the glue layer and judge the uniformity and continuity of the glue layer;
fourthly, compared with a method of adding pigment excessively, the detection method of the application has the advantages that the pigment excessively added can cause the pigment to be settled in the glue solution, namely, the glue solution at the bottom has more pigment, the glue solution at the top has less pigment, and when the glue solution is coated on the battery component subsequently, the pigment existing in the glue solution cannot be uniformly distributed on the battery component, so that the final imaging effect can be influenced when the battery component is subjected to visual imaging subsequently, so that a detector can misunderstand that the glue layer is not uniform and discontinuous, and the misjudgment rate is greatly improved;
fifth, because the battery component has a certain color, for example, when the color of the spacer is the same as the color of the pigment in the glue solution, when the glue solution with the pigment is coated on the spacer, and the spacer is visually imaged, because the color of the pigment is the same as the color of the spacer, it is difficult for a tester to determine whether the glue solution forms a glue layer on the spacer, which increases the difficulty of detection undoubtedly, but for the application, because the luminescent material is added, when the glue solution with a luminescent function is coated on the spacer, the subsequent visual imaging cannot be affected by the color of the spacer, so that the tester cannot quickly and accurately identify the glue layer;
sixth, according to the detection method of the present application, even if the thickness of the finally formed adhesive layer is thin, clear imaging can be performed on the visually imaged image due to the fact that the adhesive layer emits light, and compared with the method of adding pigments, if the color of the adhesive layer is deep enough, the thickness of the adhesive layer is undoubtedly increased, but the increase of the thickness of the adhesive layer affects the increase of the overall volume of the battery, and the energy density of the battery is reduced to a certain extent.
Further, referring to fig. 2, in an embodiment, the step S02 specifically includes:
coating the glue solution to be detected at the bottom of the inner cavity of the lower steel shell; or
Coating the glue solution to be detected on the outer side wall of the space ring; or
Coating the glue solution to be detected on the position of the inner side wall of the space ring; or
And coating the glue solution to be detected at the mutual extrusion position of the upper steel shell, the spacing ring and the lower steel shell.
Thus, it should be noted that, in the actual manufacturing process of the battery, taking the button battery as an example, glue solution needs to be applied to multiple positions of the button battery, as shown in fig. 2, which is a schematic structural diagram of the button battery 10, the button battery 20 includes a lower steel shell 21, a spacer 22, an upper steel shell 23, and an electrical core, the upper steel shell 23 is disposed in the lower steel shell 21, the spacer 22 is disposed between the lower steel shell 21 and the upper steel shell 23, the spacer 22, the lower steel shell 21 and the upper steel shell 23 are in mutual pressing contact, and the electrical core is disposed in the lower steel shell 21. Therefore, when the button cell 20 is manufactured, firstly, the glue solution to be detected is coated at the bottom position of the inner cavity of the lower steel shell 21 (the bottom position of the inner cavity of the lower steel shell 21 is the position A shown in fig. 2), then, the lower steel shell 21 is subjected to visual imaging, when the uniformity and the continuity of the glue layer of the lower steel shell 21 are judged to be good, the subsequent assembling process is carried out on the lower steel shell 21, and the like, until the button cell 20 is assembled. It should be further noted that, for the button cell 20 shown in fig. 2, there are two positions where glue is generally needed, one is at the bottom of the inner cavity of the lower steel shell (the bottom of the inner cavity of the lower steel shell 21 is position a shown in fig. 2), and the other is at the sealing position of the button cell 20 shown in fig. 2 (the sealing position of the button cell 20 is position B shown in fig. 2), and the glue application process for the button cell 20 can be completed by generally completing the glue application at the two positions.
Certainly, it should be further noted that an assembler can also glue other positions of the button cell according to actual gluing needs, for example, the glue solution to be detected is coated at the position of the outer side wall of the space ring; for another example, the glue solution to be detected is coated on the position of the inner side wall of the space ring; for another example, the glue solution to be detected is coated at the position where the upper steel shell, the spacing ring and the lower steel shell are mutually extruded. The specific gluing position is selected according to the actual battery structure, the button battery 20 is taken as an example in the application to enable the person skilled in the art to better understand the method of the application, and the battery gluing detection method of the application can be suitable for all types of batteries, such as cylindrical batteries; as another example, a pin-type battery; for another example, the special-shaped battery is not only suitable for a button battery.
It should be further noted that, in the battery gluing detection method of the present application, it is particularly emphasized that, instead of detecting the glue layer of the battery after the whole battery is assembled, the battery component to be coated with the glue solution to be detected during the assembly process of the battery also needs to be detected, and only when the uniformity and continuity of the glue layer on the battery component meet the requirements, the assembly can be continued, otherwise, the assembly is not continued.
Further, in an embodiment, the luminescent material is an active luminescent material.
Thus, it should be noted that the specific working principle of the active light emitting material, such as electroluminescent material, is not described in detail, and it is well known to those skilled in the art that the electroluminescent material is a material that emits light under the condition of power supply.
Further, in an embodiment, the luminescent material is a passive luminescent material.
Thus, it should be noted that the passive luminescent material, such as photoluminescent material, and the phosphor are a kind of passive luminescent material, and the specific working principle of the phosphor is not described in detail and is well known to those skilled in the art.
Further, in an embodiment, in the step S03:
the visual detection is CCD visual detection.
As such, it should be noted that the visual inspection is a CCD visual inspection, and the specific working principle of the CCD visual inspection is well known to those skilled in the art and will not be described in detail. Of course, the battery component can be visually detected by other visual detection methods, and the method is not limited to the CCD visual detection.
Further, in one embodiment, in step S03, the conditions for making the glue solution to be detected emit light are specifically as follows:
photoluminescence or cathodoluminescence or electroluminescence or thermoluminescence or photoluminescence or radiation.
Thus, it should be noted that the conditions for making the glue solution to be detected emit light are various even if the environment for making the glue solution to be detected emit light is various, for example, photoluminescence; as another example, cathodoluminescence; as another example, electroluminescence; as another example, thermoluminescence; as another example, light release luminescence; as another example, the radiation emits light. The specific operating principles of photoluminescence, cathodoluminescence, electroluminescence, thermoluminescence, photoluminescence and radioluminescence will not be described in detail and will be well known to the skilled person.
The battery gluing detection method of the invention obtains the glue solution to be detected by adding the luminescent material to the glue solution, the glue solution to be detected has the luminescent function, then the glue solution to be detected is coated on the battery component, finally the battery component coated with the glue solution to be detected is placed in an environment which can make the glue solution to be detected luminescent, and the battery component coated with the glue solution to be detected is visually detected, thus obtaining a clear and well-colored image, a detector can easily judge the uniformity and the continuity of the glue layer on the battery component according to the visually detected image, so that the detector can rapidly judge the glue layer on the battery component, the detection accuracy is high, because the luminescent material can luminesce under the corresponding luminescent environment, namely the glue layer has obvious brightness on the image, the detector can rapidly identify the position of the glue layer, so that the detection personnel can quickly detect the adhesive layer and judge whether the adhesive layer meets the requirements.
