Description

Technical Field

[0001] The invention relates to the technical field of lithium battery glue filling, and in particular to a glue filling tool for a lithium ion battery single-chip core. Background Art

[0002] For lithium battery modules used in specific places, it is necessary to add a glue filling process. The essence of the glue filling process is to evenly inject a medium such as electronic sealant into the assembled battery module, and the process is completed after the medium solidifies. It should also be noted that the glue filling process of battery modules or single-chip cells mainly depends on a glue filling machine.

[0003] The glue filling machine is mainly used to automatically control the glue injection amount, injection speed, glue injection temperature, vacuum degree and other related parameters. The medium is automatically poured into the designated area through the glue filling machine and relies on gravity for leveling. However, it should be noted that the battery cell structure does not have a "square" appearance structure, so the medium flow process is subject to "resistance" during the glue filling process, which may produce tiny bubbles, affecting the quality of the finished product after glue filling. On the other hand, because the flow process is "obstructed", the medium continues to "accumulate", so when the same amount of glue is continuously injected, the overall glue filling process is not completely filled and glue overflow occurs. Therefore, there is a problem of glue shortage after the glue filling is completed. This application proposes a solution. Summary of the invention

[0004] The purpose of the present invention is to provide a glue filling tool for a single-chip battery cell of a lithium-ion battery. In the glue filling operation of a single-chip battery cell in a lithium battery module, due to the limitation of the structural characteristics of the battery cell itself, the fluidity of the medium is "obstructed" during the glue filling process, which may lead to the formation of tiny bubbles, and the medium continues to "accumulate" due to the "obstructed" flow. In this process, related problems such as glue overflow occur under the premise of not being fully filled.

[0011] The two-stage action interaction unit includes glue pouring action and pre-curing action. The environmental pressure coefficient is applied synchronously in the glue pouring action and the pre-curing action, and the first-level interference action and the second-level interference action are performed respectively. The first-level interference action serves as a reference object for the second-level interference action. The first-level interference action and the second-level interference action are used to represent the air extraction action and the air replenishment action performed by the airflow component through the first air port structure and the second air port structure.

[0012] It is further set as follows: the initial pressure data is used to represent the gas pressure inside the core sleeve and the gas chamber when the directional pressure box is used to seal the core sleeve body, and is represented by Vo; the dynamic pressure data represents the gas pressure collected in real time in the gas chamber, and is represented by Vi; the calculation method of the environmental pressure coefficient M is: M= (Vi-Vo) / Vo.

[0013] It is further configured that: the glue filling tool cooperates with the glue filling machine to be provided with stage one, stage two and stage three, stage one is used for pre-treatment of the core sleeve body, stage two represents the glue filling action performed by the glue filling machine on the core sleeve body, and stage three represents the pre-curing action performed after the glue filling action is completed, and the unit air intake volume in the air filling action is set to QtA, and the unit air output volume in the air extraction action is set to QtB, including the following contents:

In combination with the above content, an action monitoring system is proposed, which takes the ambient pressure inside the core sleeve body and in the air chamber as the only variable, and the air output in the vacuum action and the air intake in the air replenishment action as variables, and subdivides the overall process into three stages. The three stages are carried out independently of each other and do not actively interfere with each other.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0027] Embodiment 1

[0028] In the glue filling operation of a single cell in a lithium battery module, due to the limitations of the cell's own structural characteristics, the fluidity of the medium is "blocked" during the glue filling process, which may lead to the formation of tiny bubbles. In addition, the medium continues to "accumulate" due to the "blocked" flow. In this process, glue overflow occurs when the cell is not fully filled. The following technical solutions are proposed:

[0029] Reference Figures 1 to 3A glue filling tool for a lithium-ion battery single-chip cell, the glue filling tool is used in a glue filling machine, and the glue filling tool includes an upper press seat 5 and a base 1, characterized in that the upper press seat 5 is located directly above the base 1, and a hydraulic drive assembly 3 corresponding to the upper press seat 5 is arranged at the four corners of the base 1, and a core sleeve body 7 is arranged at the center point of the base 1, a side pressure plate 4 is arranged at the outer wall of the core sleeve body 7, and a moving part assembly 2 corresponding to the side pressure plate 4 is arranged at the lower side of the base 1;

[0030] A directional pressing box 6 is arranged at a position just above the upper pressing seat 5 corresponding to the core sleeve body 7, in which a vertically arranged glue injection tube 10, a first air port structure 9 and a second air port structure 11 are fixedly installed, and a heating component 12 is installed at the top position inside the directional pressing box 6, and an ultrasonic vibration assembly 8 is installed at a position just below the base 1 corresponding to the core sleeve body 7;

[0031] The glue filling machine is provided with an airflow component corresponding to the first air port structure 9 and the second air port structure 11, and a glue filling component corresponding to the glue injection tube 10, and the glue filling machine is provided with an action monitoring system corresponding to the airflow component, the glue filling component, the heating component 12 and the ultrasonic vibration assembly 8;

[0032] The lower surface of the directional pressing box 6 and the upper surface of the core sleeve body 7 are in the same horizontal plane, and an air chamber is set between the inside of the directional pressing box 6 and the upper surface of the core sleeve body 7, and the heating component 12, the first air port structure 9 and the second air port structure 11 are all located in the air chamber.

[0033] Working principle: In this embodiment, it is necessary to explain first that the glue filling and packaging operation of a single-chip battery cell is different from that of a conventional lithium battery module. Specifically, because the volume of a single-chip battery cell is small, the amount of glue filled in a single filling is small. Although the glue filling machine is the main body to control the glue filling amount, glue filling temperature and colloid preparation, the specific glue filling process is due to the small internal structure space and complex structure of the single-chip battery cell. The injected colloid has the problem of "obstructed" flow. For this reason, this embodiment specifically proposes a tooling structure for the structure of a single-chip battery cell. Figure 1 , its essence is: using four side pressure plates 4 moving in opposite directions to complete the clamping and positioning process of the core sleeve body 7, and using the upper pressure seat 5 to clamp the side pressure plates 4 simultaneously, it should be noted that: the upper end of the core sleeve body 7 needs to be in the same plane as the upper surface of the side pressure plate 4, and a sealing structure such as a rubber ring can be added to the lower surface of the upper pressure seat 5, wherein the directional pressure box 6 blocks the upper end of the core sleeve body 7, so that a relatively closed environment is formed inside the core sleeve body 7, and the moving part assembly 2 is mainly used to drive the side pressure plate 4 at the corresponding position to move in a directional manner, such as conventional moving parts such as linear motors, and this part will not be repeated;

[0034] What needs to be explained in this embodiment is that: the injection tube 10 is mainly used to inject colloid into the core sleeve body 7, and the first air port structure 9 and the second air port structure 11 are used to perform air extraction and air replenishment actions on the core sleeve body 7, so as to change the gas pressure environment in the core sleeve body 7. In addition, an ultrasonic vibration assembly 8 corresponding to the core sleeve body 7 is installed in the base 1, which mainly generates vibration waves of corresponding frequencies, and directly acts on the core sleeve body 7 with vibration waves. Specifically, when the colloid is poured into the core sleeve body 7, on the basis of the natural leveling of the colloid, the vibration waves are synchronously used to assist the leveling state of the colloid. This part is an auxiliary technical point in the present invention;

[0035] It is also necessary to explain that during the specific injection process, the air extraction and air replenishment actions are performed simultaneously, including the following actions:

[0036] S1: The first air port structure 9 is used to perform an air extraction action on the inside of the core sleeve body 7, and the second air port structure 11 is used to perform an air replenishment action on the inside of the core sleeve body 7. Specifically, because there is a battery soft pack structure in the single-chip battery core, and there is a medium such as an electrolyte in the battery soft pack structure, then both the negative pressure environment and the high pressure environment will affect the structure such as the battery soft pack. Therefore, it is not allowed to directly appear a negative pressure environment or a high pressure environment before the glue filling is completed. The essence of the ventilation structure is to inject a high-density inert gas, such as helium, into the core sleeve body 7 through the airflow component. The helium settles at the bottom of the core sleeve body 7 and pushes the original gas upward. Then the essence of the air extraction structure is to extract the gas originally existing in the core sleeve body 7;

[0037] S2: Combination Figure 3 For explanation, the directional pressing box 6 just blocks the upper surface of the core sleeve body 7, so that the glue filling machine is used as the main body to control the glue filling amount during a single glue filling, and an air chamber is arranged between the top of the inner part of the directional pressing box 6 and the upper surface of the core sleeve body 7. It can be understood that: the heating component 12, the first air port structure 9, and the second air port structure 11 are all located in the air chamber.

[0038] Embodiment 2

[0039] This implementation explains the operation process of the first gas port structure and the second gas port structure associated with the action monitoring system during the glue filling process:

[0040] Reference Figure 4The motion monitoring system is mainly composed of a data integration unit, a data analysis unit and a two-level motion interaction unit, and the motion monitoring system is set by the glue filling machine. The data integration unit is used to record dynamic pressure data and initial pressure data, and send the dynamic pressure data and initial pressure data to the data analysis unit; in the data analysis unit, a pressure fluctuation model is established based on the dynamic pressure data and the initial pressure data, and the environmental pressure coefficient M is obtained by calculation in the pressure fluctuation model, and the environmental pressure coefficient is sent to the two-level motion interaction unit;

[0041] The two-stage action interaction unit includes a glue pouring action and a pre-curing action. The environmental pressure coefficient is synchronously applied to the glue pouring action and the pre-curing action and performs a primary interference action and a secondary interference action respectively. The primary interference action serves as a reference object for the secondary interference action. The primary interference action and the secondary interference action are used to represent the air extraction action and the air replenishment action performed by the airflow component through the first air port structure 9 and the second air port structure 11.

[0042] The initial pressure data is used to represent the gas pressure inside the core sleeve body 7 and the gas chamber when the directional pressure box 6 blocks the core sleeve body 7, and is represented by Vo. The probe position of the gas pressure sensor is located inside the gas chamber, and the dynamic pressure data is the gas pressure collected in real time in the gas chamber, represented by Vi. It should be noted that before the glue filling action is performed, Vo=Vi, and Vo is a constant value. However, during the glue filling action, it can be understood that: the colloid is continuously poured into the core sleeve body 7, and the space volume of the retained gas continues to shrink, so that Vi continues to rise based on Vo. The essence of the pressure fluctuation model is a two-dimensional coordinate system, in which the X-axis is the time unit and the Y-axis is the pressure value, so that the real-time collected Vi is input into the pressure fluctuation model to obtain a pressure fluctuation curve;

[0043] Then, combined with the above content, the following stages are set in the overall operation process:

[0044] Stage 1: After the upper pressure seat 5 completes the blocking and fixing process of the side pressure plate 4 and the core sleeve body 7, the air replenishment action is performed before the air extraction action. The high-density inert gas is injected into the core sleeve body 7 through the second air port structure 11, and Vi is recorded. In stage 1, the calculation method of the environmental pressure coefficient M is: M=(Vi-Vo) / Vo, so the first-order critical value A1=0.27 of the environmental pressure coefficient M is set in this stage. When M>0.27, the air extraction action is performed synchronously to extract the gas in the core sleeve body 7 and the gas chamber;

[0045] Stage 2: When stage 1 continues, the glue filling action is performed until Vi=1.21*Vo, and the air extraction action is performed synchronously during the glue filling action, and the ultrasonic vibration assembly 8 is started to provide a vibration wave of a corresponding frequency to the inside of the core sleeve body 7. In stage 2, the second-order critical value A2 of the environmental pressure coefficient M is set to 1.46. Specifically, when M>1.46, the air extraction action is started synchronously to extract the gas in the gas chamber;

[0046] Stage three: Stage three is carried out synchronously after stage two is completed, that is, after the glue filling action is completed in stage two, the glue filled in the core sleeve body 7 is pre-cured by starting the heating component 12. In this process, the air replenishment action is performed synchronously, and the third-order critical value A3=1.58 in the ambient pressure coefficient M is set. The annular pressure coefficient range of 1.58<M<1.63 is maintained by the air replenishment action.

[0047] Embodiment 3

[0048] This embodiment is described in conjunction with the second embodiment:

[0049] The key variables in the secondary interference action and the primary interference action are the unit gas intake volume of the high-density inert gas injected into the gas bin in the gas replenishment action and set to QtA, and the unit gas output volume of the gas retained in the gas bin when it is extracted in the gas extraction action and set to QtB. It should be noted that: when QtA=QtB, it corresponds to the state of Vo=Vi, and the following is explained in combination with the stages 1 to 3 in the embodiment:

[0050] The explanation for stage 1 is as follows: high-density inert gas is continuously injected with a unit air intake of QtA, in order to satisfy the condition of M>0.27, which means Vi>Vo and the ambient pressure inside the core sleeve body 7 needs to be reduced in time, so that QtB=(1+M-0.27)*QtA, until Vi=1.21*Vo is satisfied;

[0051] The explanation for stage 2 is: when the air pumping action is not performed, the injection process of the colloid will also cause the internal environmental pressure of the core sleeve body 7 to rise. In this process, the air replenishment action is not performed but the air pumping action is performed independently. Its essence is combined with the glue injection amount of the glue injection tube 10 per unit time, and the glue injection amount of the colloid per unit time is controlled by the glue injection machine, which is represented by HtA in this embodiment. A simple explanation for this is: as the colloid is continuously injected, the internal space of the core sleeve body 7 is reduced and the "compressed" gas causes the internal environmental pressure to rise, thereby synchronously performing the air pumping action to reduce the internal environmental pressure. In this stage, only the gas output QtB is limited, which is specifically expressed as: QtB=HtA*k*(M-0.46), where k is used to represent the conversion factor between the colloid density and the gas density;

[0052] For stage three, specifically, after stage two is completed, specifically, after the glue filling action is completed, and based on Vi in stage two, and because it is necessary to synchronously start the heating component 12 for pre-curing, in this process, on the one hand, because of the pressure change caused by the heating process, on the other hand, because the soft package structure in the single-chip battery structure has been completely wrapped by the colloid, a high-pressure environment can be used to squeeze out the tiny bubbles in the colloid;

[0053] Then it can be understood as: in this state, the high-density inert gas is continuously replenished with QtA maintained unchanged during the air replenishment action. First, the condition M>1.58 needs to be satisfied. Its essence is to first perform the air replenishment action independently until M>1.58 is satisfied. Then, as the temperature in the gas chamber rises, the pressure rises. When M<1.63 occurs, the air pumping action is carried out synchronously, and the gas output QtB in the air pumping action is optimized to: QtB=QtA*(2.63-M), so that the air pumping action continues with QtA*(2.63-M) until M>1.58 is satisfied.

[0054] In summary: based on the glue filling process in the production process of lithium batteries, and especially for single-chip cells with relatively small volume, a directional clamping method is used to complete the internal sealing of the single-chip cell, and vibration / high-voltage assisted leveling and pressure environment self-inspection are added as auxiliary methods. Its essence is to use the ambient pressure inside the core sleeve body and the air chamber as the only variable, and the air output in the vacuum action and the air intake in the air replenishment action as variables, and the overall process is subdivided into three stages. The three stages are carried out independently of each other and do not actively interfere with each other. Instead, the three stages are interfered in a related manner through primary and secondary interference actions. Specifically, the air output and air replenishment volumes are limited to ensure relative stability in the glue filling environment. The high-pressure environment can be used to "actively" extrude the colloid to further assist leveling.

The annular pressure coefficient range is maintained at 1.58<M<1.63 through the air supply action, and QtB in the air extraction action is optimized to QtA*(2.63-M) and continued until M>1.58 is satisfied.
