Description

Technical Field

[0001] The present application belongs to the field of battery technology, and more specifically, relates to a glue-filled battery. Background Art

[0002] The battery of PDA / POS machine usually adopts low-pressure glue filling technology to complete the glue filling operation. Battery glue filling refers to injecting a mixture containing thermosetting or hardening glue into the battery shell, and then drying and curing the glue to form a solid in the battery shell. Glue filling can increase the shock resistance and waterproof performance of the battery, making it suitable for more working environments.

[0003] However, a common problem in the assembly process of low-pressure glue filling is the instability of the thickness of the battery cell. Since there may be differences in the thickness of the battery cell during the production process, the glue is easy to overflow from the steel sheets adhered to both sides of the battery cell during the glue filling process. This not only affects the appearance quality of the battery, but may also cause the battery performance to deteriorate and even pose a safety hazard. In order to solve this problem, the manufacturer usually uses an additional process of pasting a masking material to remedy it. After glue filling, the staff needs to paste an additional layer of masking material on the surface of the steel sheet to cover the overflowing glue, thereby improving the appearance of the battery. However, this practice not only increases labor costs and reduces production efficiency, but may also have an adverse effect on the overall performance of the battery. The pasting of masking materials may introduce new impurities or bubbles, affecting the insulation performance and stability of the battery. Utility Model Content

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] In order to solve the technical problem that glue-filled batteries are prone to overflow during glue filling, Figure 1 and Figure 2As shown, the present application provides a glue-filled battery, including an outer frame 1, an end cover 2 and a battery cell 3. The outer frame 1 is the main body of the entire battery, and has a battery cell installation groove 12 for accommodating the battery cell 3. The battery cell installation groove 12 provides a stable installation space for the battery cell 3, and also has an opening 11 on the battery cell installation groove 12, so that the battery cell 3 can be smoothly placed in the battery cell installation groove 12. More importantly, the battery cell installation groove 12 is also used to load the filled colloid to ensure that the colloid can surround the battery cell 3, thereby improving the overall performance and safety of the battery. The end cover 2 is provided at the opening 11 of the battery cell installation groove 12, which plays the role of sealing and protecting the battery cell 3. It is worth mentioning that the end cover 2 is not directly adhered to the surface of the battery cell 3, so that the filled colloid can flow into the gap between the end cover 2 and the battery cell 3, avoiding the colloid from overflowing out of the battery. Not only the cleanliness and efficiency in the production process are improved, but also the stability and durability of the finished battery are enhanced. The battery cell 3, as the core component of the glue-filled battery, is placed in the battery cell installation groove 12. The remaining space of the battery cell installation groove 12 is used to fill the colloid. The glue-filled battery of the present application can ensure that the colloid covers and protects the battery cell 3 more comprehensively, and solves the problem of easy glue overflow, thereby improving the working stability and service life of the glue-filled battery in various environments.

[0039] In one embodiment of the present application, the opening 11 includes a first opening located at the front end face of the outer frame 1 and a second opening located at the rear end face of the outer frame 1. The battery cell 3 can be flexibly selected to be placed in the battery cell installation groove 12 from the first opening or the second opening, thereby improving the convenience of operation. The end cover 2 includes a first end cover provided at the first opening and a second end cover provided at the second opening. The first end cover is provided corresponding to the front end face of the battery cell 3, and the second end cover is provided corresponding to the rear end face of the battery cell 3. During the glue filling process, the colloid can flow into the gap between the first end cover and the battery cell 3, or flow into the gap between the second end cover and the battery cell 3, thereby avoiding the overflow of the colloid.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, an end cap slot 13 is provided at the opening 11, and the end cap 2 is connected to the end cap slot 13. The end cap slot 13 is specifically a groove provided at the opening 11, and the shape and area of ​​the end cap slot 13 are consistent with the shape and area of ​​the end cap 2, and the area of ​​the end cap slot 13 is larger than the area of ​​the opening 11, so as to ensure that the end cap 2 can completely cover and close the opening 11 after installation. When the end cap 2 is connected to the end cap slot 13, the opening 11 is completely closed, which can effectively prevent the glue from overflowing. It is worth mentioning that after the end cap 2 is installed, the outer surface of the end cap 2 is basically flush with the surface of the outer frame 1, which not only improves the aesthetics of the product, but also enhances the stability of its overall structure.

[0041] In one embodiment of the present application, a first glue injection hole group and a second glue injection hole group are provided on the outer frame 1, and the first glue injection hole group and the second glue injection hole group are respectively arranged on both sides of the battery cell 3. Specifically, the first glue injection hole group is located on the left side of the battery cell 3, and the second glue injection hole group is located on the right side of the battery cell 3. After the battery cell 3 is installed in the battery cell installation groove 12, the operator can inject glue into the battery cell installation groove 12 from the first glue injection hole group and the second glue injection hole group respectively. Such a two-way glue injection method not only ensures that the glue can evenly cover the battery cell 3 and the surrounding area, but also effectively improves the efficiency and quality of glue injection.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the number of the glue holes 14 in the first glue hole group and the second glue hole group is at least 3, and these glue holes 14 correspond to different parts of the battery cell 3, namely the front section, the middle section and the rear section of the battery cell 3. The glue holes 14 are arranged in sequence along the length direction of the outer frame 1, which helps the glue to be evenly distributed inside the battery cell mounting groove 12, avoiding glue accumulation or filling omission.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a plurality of support protrusions 15 are provided on the inner wall of the outer frame 1, and each support protrusion 15 is distributed on both sides of the battery cell 3 to support both sides of the battery cell 3, thereby ensuring that the battery cell 3 can remain stable in various working environments and preventing the battery cell 3 from shaking or shifting during glue filling or use.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the glue-filled battery includes a water immersion identification member 4. When the battery accidentally contacts water during testing or use, the water immersion identification member 4 will produce an obvious color change, which becomes an intuitive basis for judging whether the battery is immersed in water. The water immersion identification member 4 is specifically installed in the identification installation groove 16 on the outer wall of the outer frame 1. The setting of the identification installation groove 16 not only takes into account the convenience of installation of the water immersion identification member 4, but also ensures the installation stability of the water immersion identification member 4.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the glue-filled battery also includes a circuit board 5, which is arranged in the battery cell mounting groove 12 and is electrically connected to the battery cell 3. The circuit board 5 mainly plays a role in conducting and protecting the battery cell 3 when supplying / charging to the outside. Because the lithium battery cell 3 cannot withstand extreme conditions such as overcharging, over-discharging, overcurrent, short circuit, and ultra-high temperature charging and discharging. These improper operations may not only damage the battery, but also cause serious safety accidents. Therefore, in order to ensure the stable operation of the battery and the safety of the user, the working status of the battery cell 3 is monitored in real time through the circuit board 5, thereby ensuring the safe and stable operation of the battery.

[0046] like Figure 3 As shown, in one embodiment of the present application, a circuit board support hole 17 is further provided on the outer frame 1. Specifically, the circuit board 5 is inserted into the outer frame 1 through the circuit board support hole 17. In order to ensure stable support of the circuit board 5, the number of the circuit board support holes 17 is set to at least 3, and these holes are arranged in a triangular shape on the plane of the circuit board 5 to form a triangular support relationship for the circuit board 5. Each circuit board support hole 17 can effectively disperse the weight of the circuit board 5 and make it evenly supported on the outer frame 1. This layout not only enhances the stability of the circuit board 5, but also effectively prevents the hardware components from sinking due to long-term use or gravity, which not only improves the overall performance of the glue-filled battery, but also provides users with a safer and more reliable use experience.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the glue-filled battery further includes a buffer member 6 arranged in pairs, and the circuit board 5 is sandwiched between the buffer members 6 arranged in pairs, providing all-round support and protection for the circuit board 5. The buffer member 6 is specifically made of insulating foam, and this choice fully considers its protective effect and safety on the circuit board 5. The insulating foam has good insulation properties and can effectively prevent the circuit board 5 from short circuiting or damage caused by external factors. At the same time, its soft and elastic characteristics can play a good buffering role when the circuit board 5 is impacted or vibrated, protecting the circuit board 5 from damage.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
