Description

Technical Field

[0001] This utility model relates to the field of battery cell coating technology, and more specifically, to an adhesive weighing device. Background Technology

[0002] In the battery module manufacturing process, the installation of cylindrical cells typically requires 360° adhesive application within the cell slot to ensure the cells are firmly secured after the adhesive cures. Currently, widely used cylindrical cell models include 21700 cells and lithium iron phosphate batteries. Precise control of the adhesive application amount is a key factor affecting the cell installation quality and the overall stability of the module. Insufficient adhesive may result in weak fixation, while excessive adhesive may cause overflow, contaminate the cells, or increase the module weight, affecting battery performance and subsequent assembly. The commonly used adhesive weighing method is the "whole plate weighing method," which involves weighing the entire coated workpiece and estimating the adhesive amount for a single cell slot using the "total weight / number of holes" method.

[0003] Existing adhesive coating weighing devices have the technical problem of being unable to detect deviations in the amount of adhesive applied to a single hole. Therefore, there is an urgent need to provide a weighing method and supporting tooling system that can achieve single-hole weighing, is easy to operate, and is adaptable to various battery cell models, in order to improve the quality control level of the adhesive coating process and meet the requirements of high-precision manufacturing of battery modules.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] In the battery module manufacturing process, the installation of cylindrical cells typically requires 360° adhesive application within the cell slot to ensure the cells are firmly fixed after the adhesive cures. Currently, widely used cylindrical cell models include 21700 cells and lithium iron phosphate batteries. Precise control of the adhesive application amount is a key factor affecting the cell installation quality and the overall stability of the module. Insufficient adhesive may lead to insecure fixing, while excessive adhesive may cause overflow, contaminate the cells, or increase the module weight, affecting battery performance and subsequent assembly. The commonly used adhesive weighing method is the "whole plate weighing method," which involves weighing the entire coated workpiece and estimating the adhesive amount for a single cell slot using the "total weight / number of holes" method. However, this method has the following drawbacks:

[0036] 1. Inability to detect single-hole glue application deviation: The whole board weighing method can only obtain the average glue application amount and cannot identify the abnormal glue application amount of individual cell cells, resulting in a blind spot in quality control;

[0037] 2. Untraceable weighing data: During the test, the plastic workpiece needs to be wiped repeatedly to remove residual glue, which makes it difficult for the weighing data to be consistent before and after weighing, and the test results cannot be effectively retained and verified;

[0038] 3. Large errors due to manual operation: Due to the lack of standardized operating procedures, there are risks of missed detections and misoperations during manual operation;

[0039] 4. Lack of effective clamping and positioning devices: During the glue application process, the blister pack is prone to shifting due to the scraping of the glue nozzle, affecting the weighing accuracy and the consistency of glue application quality.

[0040] To address the aforementioned issues, there is an urgent need for a weighing method and supporting tooling system that enables single-hole weighing, is easy to operate, and is adaptable to various battery cell models. This would improve the quality control level of the adhesive coating process and meet the requirements of high-precision battery module manufacturing.

[0041] Please refer to Figures 1-5 This embodiment provides an adhesive weighing device 100, which can effectively improve the technical problems mentioned above, realize single-hole weighing, facilitate operation, and improve the quality of adhesive application.

[0042] Please refer to Figures 1-5 This embodiment provides an adhesive weighing device 100, including an upper cover 10, a base 20, a blister box 30, and a weighing component. The base 20 and the upper cover 10 are detachably connected, the blister box 30 is detachably installed on the base 20, the interior of the blister box 30 is used for applying adhesive, and the weighing component is used to weigh the blister box 30 after applying adhesive.

[0043] Understandably, there are multiple blister packs 30, each detachably connected to the base 20. After each blister pack 30 is individually coated with glue, it can be removed from the base 20 and placed on a weighing device for weighing. This satisfies the requirement for accurate weighing and detection of the glue amount applied to each hole. By detachably installing the blister packs 30 to the base 20 and weighing each blister pack 30 individually after glue application, the glue weight of each 101-position glue hole can be accurately obtained. This effectively solves the problem that traditional whole-board weighing methods can only obtain average values ​​and cannot detect single-hole deviations, improving the accuracy and reliability of quality control. Furthermore, each blister pack 30 can be weighed individually, allowing the weight data of each glued sample to be recorded independently, facilitating subsequent quality tracking and data analysis, and meeting the requirements for quality monitoring and traceability in the production process.

[0044] In this embodiment, the blister box 30 includes a box body 31 and an outer edge 32. The outer edge 32 is connected to the top edge of the box body 31. The interior of the box body 31 is used for applying adhesive. The outer edge 32 is disposed between the base 20 and the top cover 10. The outer edge 32 has a ring-shaped structure, and the box body 31 has a cylindrical structure. The outer edge 32 is disposed along the circumference of the box body 31 at its top edge. It can be understood that the box body 31 and the outer edge 32 are integrally formed.

[0045] Specifically, the base 20 is provided with a mounting groove 201, and the box body 31 is disposed in the mounting groove 201. The bottom of the outer edge 32 abuts against the edge of the mounting groove 201. The box body 31 of the blister box 30 can be accommodated in the mounting groove 201, and the outer edge 32 is mounted on the periphery of the mounting groove 201, thereby abutting against the top surface of the base 20, so that the blister box 30 is placed on the base 20. Then, the top cover 10 covers the top of the base 20. The top cover 10 and the base 20 can jointly clamp the outer edge 32 of the blister box 30, thereby fixing the blister box 30.

[0046] Specifically, the number of blister boxes 30 corresponds one-to-one with the number of mounting slots 201.

[0047] It should also be noted that the mounting groove 201 includes a first mounting groove 2011 and a second mounting groove 2012, with the diameter of the first mounting groove 2011 being larger than the diameter of the second mounting groove 2012. The first mounting groove 2011 and the second mounting groove 2012 can be adapted to different models of battery cell blister packs 30, thereby improving the versatility and flexibility of the glue weighing device 100.

[0048] In this embodiment, there are three first mounting slots 2011 and three second mounting slots 2012, with the three first mounting slots 2011 and the three second mounting slots 2012 arranged at linear intervals. In other embodiments, the number of first mounting slots 2011 and the number of second mounting slots 2012 may be increased or decreased, and no specific limitation is made here.

[0049] Furthermore, the glue weighing device 100 also includes a magnetic suction component 40, through which the upper cover 10 and the base 20 are magnetically connected. The magnetic suction component 40 includes a first magnetic suction component 41 and a second magnetic suction component 42. The first magnetic suction component 41 is mounted on the base 20, and the second magnetic suction component 42 is mounted on the upper cover 10. The first magnetic suction component 41 and the second magnetic suction component 42 are magnetically connected, thereby connecting the base 20 and the upper cover 10. The outer edge 32 is disposed between the first magnetic suction component 41 and the second magnetic suction component 42. The magnetic connection between the upper cover 10 and the base 20 via the first magnetic suction component 41 and the second magnetic suction component 42 stabilizes the position of the blister pack 30 during glue application, preventing the blister pack 30 from shifting due to nozzle scraping, thus ensuring the consistency and accuracy of glue application and subsequent weighing data.

[0050] In addition, in order not to affect the magnetic connection between the top cover 10 and the base 20, the outer edge 32 of the blister box 30 is provided with a through hole 321. After the top cover 10 covers the base 20, the second magnetic component 42 is magnetically connected to the first component through the through hole 321.

[0051] Furthermore, the upper cover 10 is provided with an adhesive application hole 101, the position of which is adapted to the position of the mounting groove 201. After the upper cover 10 and the base 20 are magnetically connected, adhesive is applied into the blister box 30 through the adhesive application hole 101.

[0052] It should also be noted that the upper cover 10 is equipped with lifting rings 50, which are used to connect external lifting devices to move the upper cover 10. There are two lifting rings 50, which are respectively set at both ends of the upper cover 10. After the lifting devices are connected to the lifting rings 50, the lifting devices can move the upper cover 10 through the lifting rings 50.

[0053] In this embodiment, the upper cover 10 and the base 20 are detachably connected, which facilitates the quick installation and replacement of the blister box 30 and improves testing efficiency. Specifically, the bottom of the upper cover 10 is provided with a positioning pin 60, and the base 20 is provided with a positioning hole 70, and the positioning pin 60 and the positioning hole 70 cooperate with each other.

[0054] In this embodiment, there are four positioning pins 60. The four positioning pins 60 are respectively arranged along the circumferential direction at the edge of the bottom of the upper cover 10, and the position of the positioning hole 70 is adapted to the position of the positioning pin 60.

[0055] In this embodiment, the weighing device is an electronic scale.

[0056] In summary, this utility model embodiment provides an adhesive weighing device 100, which includes an upper cover 10, a base 20, a blister box 30, and a weighing component. The base 20 and the upper cover 10 are detachably connected, and the blister box 30 is detachably installed on the base 20. The interior of the blister box 30 is used for applying adhesive, and the weighing component is used to weigh the blister box 30 after adhesive application. In use, the blister box 30 is placed on the base 20, and then the upper cover 10 and the base 20 are detachably connected to ensure that the blister box 30 is stably installed and will not deviate during the adhesive application process, thus affecting the weighing accuracy. Adhesive is applied inside the blister box 30. After the adhesive application is completed, the upper cover 10 is quickly removed, and the blister box 30 is taken out of the base 20. The glued blister box 30 is then placed on the weighing component for weighing to check whether it is within the required weight range, and the weight is recorded. The glue weighing device 100 can accurately weigh and detect the amount of glue applied to a single hole through the blister box 30. By detachably installing the blister box 30 on the base 20 and weighing each blister box 30 after glue application, the glue weight of each glue application hole 101 can be accurately obtained. This effectively solves the problem that the traditional whole board weighing method can only obtain the average value and cannot detect the deviation of a single hole, thus improving the accuracy and reliability of quality control.
