Description

Technical Field

[0001] This application belongs to the field of battery cell technology, specifically relating to a battery cell assembly device. Background Technology

[0002] With the rapid development of the battery industry, the requirements for battery assembly processes are becoming increasingly stringent. Traditional semi-automatic assembly methods can no longer meet the needs of modern production; therefore, automated and intelligent assembly technologies have emerged. Among them, the PSA (Pressure Sensitive Adhesive) activation mechanism, as an advanced automated device, is gradually becoming the mainstream choice in the battery industry. This technology, through a precise mechanical structure, achieves accurate clamping between the battery adhesive and the casing, ensuring the stability and reliability of the battery during assembly. Simultaneously, the PSA activation mechanism is highly efficient, significantly improving battery production efficiency and product quality. Furthermore, this mechanism boasts advantages such as simple structure and easy assembly / disassembly, providing strong technical support for battery production.

[0003] In related technologies, due to the lack of an effective feedback mechanism in the PSA activation mechanism, unqualified products are still activated even when there is a deviation in the relative position of the battery and the casing. This causes unqualified products to be mixed with qualified products, reducing the product yield. Utility Model Content

[0036] The battery cell assembly equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0037] like Figures 1 to 8As shown, a battery cell assembly device according to some embodiments of this application is used to press a battery cell assembly 10; the battery cell assembly 10 includes a housing 11 and a battery cell 12; the battery cell assembly device has a first direction X, and the battery cell 12 and the housing 11 are stacked along the first direction X; the battery cell assembly device includes: a base 42, a pressing detection mechanism 20, and an early warning module (not shown in the figure); the pressing detection mechanism 20 is mounted on the base 42; a working area is provided on the base 42, and the battery cell assembly 10 is disposed in the working area; the pressing detection mechanism 20 is disposed on at least one side of the working area along the first direction X; the pressing detection mechanism 20 includes a pressing component 21 and a detection component 22; the pressing component 21 is movable relative to the working area along the first direction X; the detection component 22 is disposed on the base 42 and / or the pressing component 21, and is used to detect the relative position between the battery cell 12 and the housing 11; the early warning module is electrically connected to the detection component 22, and the early warning module is used to issue an early warning based on the relative position between the battery cell 12 and the housing 11.

[0038] In this embodiment, the battery cell 12 and the housing 11 in the battery cell assembly 10 are stacked along the first direction X. The pressing detection mechanism 20 is mounted on the base 42, which has a working area. The battery cell assembly 10 is located in the working area. The pressing detection mechanism 20 is located on at least one side of the working area along the first direction X. The pressing component 21 in the pressing detection mechanism 20 can move relative to the working area along the first direction X. Thus, during the movement of the clamping assembly 21 along the first direction X, the clamping assembly 21 can clamp the housing 11 and the battery cell 12, ensuring close contact between them. Simultaneously, since the detection assembly 22 is mounted on the clamping assembly 21, it can detect the relative position between the battery cell 12 and the housing 11 and send this relative position information to the warning module. When the relative position between the battery cell 12 and the housing 11 meets the requirements, the warning module does not alarm; when the relative position between the battery cell 12 and the housing 11 does not meet the requirements, the warning module alarms, indicating that the battery cell assembly 10 is unqualified. At this time, the operator can remove the unqualified battery cell assembly 10, preventing it from entering the qualified product batch, thereby improving the product yield.

[0039] In some embodiments, the battery cell assembly 10 further includes an adhesive layer; the adhesive layer is disposed between the housing 11 and the battery cell 12; the adhesive layer may be at least one of double-sided adhesive or pressure-sensitive adhesive (PSA).

[0040] For example, the adhesive layer can be a PSA, which is characterized by being able to adhere to the surface of an object immediately after applying slight pressure and maintaining its adhesiveness for a long time. Before the cell assembly 10 is pressed, the PSA is in an inactive state, that is, the housing 11 and the cell 12 are in slight contact with the PSA, and the adhesiveness of the PSA is not activated. After the pressing assembly 21 contacts the cell 12, the pressing assembly 21 applies force to the cell 12, so that the PSA is fully attached to the surface of the housing 11 and the cell 12, thereby activating the adhesiveness of the PSA.

[0041] It should be noted that the work area is as follows: Figure 1 The location of the battery cell assembly 10 is shown. The first direction X is... Figure 1 The direction indicated by the X-axis.

[0042] In some embodiments, the detection component 22 may be configured as at least one of a barometric pressure detection component 22, a sensor detection component 22, and a visual detection component 22.

[0043] For example, the detection component 22 can be configured as a sensor detection component 22, such as a distance sensor; the sensor detection component 22 can be disposed on the clamping component 21. Before PSA activation, the sensor component can detect the relative position of the cell 12 and the housing 11, which has higher flexibility and adaptability, can meet the needs of different specifications and models of cell 12, and will not cause misjudgment due to wear of the air pressure detection component 22, and the effect is more accurate.

[0044] For example, the detection component 22 can be set as a vision detection component 22, such as a CDC camera; the vision detection component 22 can be set on the clamping component 21. Before PSA activation, the vision detection component 22 can monitor the position and orientation of the cell 12 in real time, with higher accuracy and detection range; at the same time, after the shaping structure work is completed in this application, the vision detection component 22 can also detect the relative position of the flexible board 13 and the interface of the test equipment, which is convenient for subsequent production.

[0045] It should be noted that, Figure 1 Each mechanism in the system is supported by a base 42 for mounting the mechanism; of course, the base 42 can also be a single unit, with each mechanism installed at its corresponding position on the base 42.

[0046] Optionally, such as Figure 4 and Figure 5As shown, the detection component 22 includes an adsorption element 221, an adapter 222, a pressure detection element (not shown in the figure), and a negative pressure element (not shown in the figure). The adsorption element 221 is disposed on the pressing component 21. The adsorption element 221 has multiple through holes, which are respectively connected to the adapter 222. The pressure detection element is connected to the adapter 222, and the negative pressure element is connected to the pressure detection element. The negative pressure element is used to evacuate air from the multiple through holes to create a negative pressure state in the multiple through holes. The pressure detection element is electrically connected to the early warning module. The pressure detection element is used to detect the pressure change value in the adapter 222. The early warning module is used to determine the relative position between the battery cell 12 and the housing 11 based on the pressure change value and to issue an early warning.

[0047] In this embodiment, the adsorption member 221 is disposed on the pressing assembly 21. The adsorption member 221 has multiple through holes, which are respectively connected to the adapter 222. The air pressure detection member is connected to the adapter 222, and the negative pressure member is connected to the air pressure detection member. In this way, after the air pressure detection element contacts the battery cell 12, a seal is formed between the battery cell 12 and the multiple through holes. The multiple through holes are evacuated by the negative pressure element to form a negative pressure state. After the negative pressure state is formed, the negative pressure element is disconnected, and the warning module reads the first air pressure value of the air pressure detection element when the negative pressure element is disconnected. After a period of time, the warning module reads the second air pressure value of the air pressure detection element again. If the difference between the first air pressure value and the second air pressure value is zero, it means that there is no deviation in the relative position of the battery cell 12 and the housing 11, and the battery cell 12 completely covers the through holes in the adsorption component 221. If the difference between the first air pressure value and the second air pressure value is not zero, it means that there is a deviation in the relative position of the battery cell 12 and the housing 11, which causes the battery cell 12 to not completely cover the through holes in the adsorption component 221, indicating that the sealing between the battery cell 12 and the adsorption component 221 is poor.

[0048] Specifically, such as Figure 5 As shown, the area enclosed by the multiple through holes in the adsorption element 221 is equal to the side surface area of ​​the battery cell 12. Thus, if the position of the battery cell 12 deviates, the battery cell 12 cannot completely cover the multiple through holes, allowing the pressure detection element to detect pressure changes.

[0049] Optionally, such as Figures 1 to 3 As shown, there are two battery cells 12, which are respectively located on both sides of the housing 11 along the first direction X; there are two clamping detection mechanisms 20, which are respectively located on both sides of the working area along the first direction X; each clamping detection mechanism 20 can move relative to the working area along the first direction X.

[0050] In this embodiment, two battery cells 12 are provided, each located on one side of the housing 11 along the first direction X; two clamping detection mechanisms 20 are also provided, each located on one side of the working area along the first direction X, and each mechanism can move relative to the working area along the first direction X. Thus, the two clamping detection mechanisms 20 clamp the battery cells 12, thereby improving work efficiency.

[0051] In some embodiments, such as Figure 3 As shown, the housing 11 includes two mounting surfaces, which are arranged opposite to each other along the first direction X. Each battery cell 12 is disposed on one mounting surface and is exposed in the housing 11, so that each clamping assembly 21 can clamp the corresponding battery cell 12.

[0052] Optionally, such as Figure 4 and Figure 5 As shown, the clamping assembly 21 includes a first driving member 211 and a clamping block 212; the first driving member 211 is disposed on at least one side of the base 42 along the first direction X, and the clamping block 212 is connected to the first driving member 211. The first driving member 211 is used to drive the clamping block 212 to move along the first direction X to clamp the battery cell assembly 10.

[0053] In this embodiment, the first driving member 211 is disposed on at least one side of the base 42 along the first direction X, and the clamping block 212 is connected to the first driving member 211. This allows the first driving member 211 to drive the clamping block 212 to move along the first direction X, thereby contacting the battery cell 12 and clamping the battery cell 12, the adhesive layer, and the housing 11.

[0054] In some embodiments, the first driving member 211 can be configured as a first slide cylinder; the first slide cylinder includes a first cylinder and a first slide; the first cylinder is mounted on the base 42, the first slide is movably connected to the first cylinder, and the pressing block 212 is mounted on the first slide. Thus, the cylinder can drive the slide to move, thereby causing the pressing block 212 to move along the first direction X. The slide cylinder has the characteristics of precise positioning and precise pressing; therefore, configuring the first driving member 211 as a slide cylinder allows for precise control of the pressing block 212, thereby achieving precise pressing. Of course, the first driving member 211 can also be configured as a drive motor, drive piston, or other driving member; this application does not impose any limitations on this.

[0055] Furthermore, a slide rail can be provided on the slide of the slide cylinder, and the clamping block 212 can be slidably connected to the slide rail; a buffer 23 can be provided between the clamping block 212 and the slide, with one end of the buffer 23 connected to the slide and the other end connected to the clamping block 212. In this way, during the contact process between the clamping block 212 and the battery cell 12, the problem of damage to the battery cell 12 caused by hard contact between the clamping block 212 and the battery cell 12 is avoided.

[0056] In some embodiments, the buffer 23 can be configured as a compression spring, and multiple compression springs can be configured; specifically, multiple compression springs are spaced apart between the clamping block 212 and the slide. This ensures that the clamping block 212 is subjected to uniform force, thereby providing uniform force to the clamping block 212 after it comes into contact with the battery cell 12. Alternatively, elastic elements such as elastic rubber can be used to provide cushioning for the clamping block 212, and this embodiment does not limit this application.

[0057] Optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, it also includes a shaping mechanism 30; the battery cell assembly 10 also includes a flexible board 13, which is disposed inside the housing 11 and electrically connected to the battery cell 12; the flexible board 13 has a bending section, and the shaping mechanism 30 has a shaping part corresponding to the bending section; the shaping mechanism 30 is movably connected to the base 42, and the shaping mechanism 30 can move relative to the working area so that the shaping part abuts against the corresponding bending section and shapes the bending section.

[0058] In this embodiment, by providing a shaping part corresponding to the bending segment in the shaping mechanism 30, and by movably connecting the shaping mechanism 30 to the base 42, the shaping mechanism 30 can move relative to the working area. This allows the bending segment to be shaped by the shaping part contacting the corresponding bending segment.

[0059] like Figure 2 and Figure 3 As shown, the flexible board 13 has a bending section before shaping. The bending section needs to be located at its preset position to avoid the bending section protruding from the shell 11 during subsequent assembly because it is not in the preset position. This would require shaping the bending section protruding from the shell 11 during subsequent assembly, making the assembly more complicated and the assembly efficiency lower.

[0060] Optionally, such as Figure 3 and Figure 5 As shown, the shaping mechanism 30 includes a first shaping member 31; the first shaping member 31 is disposed on one side of the working area along the first direction X, the shaping part includes a first sub-shaping part 312 disposed on the first shaping member 31, the bending section includes a first sub-bending section 131, the first sub-shaping part 312 is disposed opposite to the first sub-bending section 131, the first sub-shaping part 312 can move relative to the first sub-bending section 131 along the first direction X, so as to abut against the first sub-bending section 131 and shape the first sub-bending section 131.

[0061] In this embodiment, a first shaping member 31 is disposed on one side of the working area along the first direction X. The first shaping member 31 has a first sub-shaping portion 312, which is disposed opposite to the first sub-bending segment 131. The first sub-shaping portion 312 moves relative to the first sub-bending segment 131 along the first direction X to abut against and shape the first sub-bending segment 131. In this way, the first sub-bending segment 131 is shaped by the first sub-shaping portion 312, preventing the first sub-bending segment 131 from protruding from the housing 11 along the first direction X, thus avoiding interference with subsequent assembly.

[0062] In some embodiments, the shaping mechanism 30 may include a fourth driving member disposed on the base 42. The first shaping member 31 includes a first shaping member body 311 and a first sub-shaping portion 312. The first shaping member body 311 is connected to the fourth driving member, and the first sub-shaping portion 312 is disposed on the first shaping member body 311. The fourth driving member can drive the first shaping member 31 to move toward the first sub-bending segment 131. In this way, driving the first shaping member 31 by a separate fourth driving member is beneficial to improving the flexibility of the first shaping member 31.

[0063] It should be noted that the first sub-shaping part 312 can be made of soft materials such as silicone or rubber to avoid hard contact between the first sub-shaping part 312 and the first sub-bending section 131, which could damage the first sub-bending section 131.

[0064] It should be noted that the fourth driving component can be the same as or different from the first driving component 211.

[0065] Optionally, such as Figure 5 As shown, the first shaping component 31 is disposed on the clamping assembly 21, and the clamping assembly 21 can drive the first shaping component 31 to move along the first direction X.

[0066] In this embodiment, by placing the first shaping component 31 on the clamping assembly 21, the clamping assembly 21 can drive the first shaping component 31 to move along the first direction X. Thus, during the clamping process of the clamping assembly 21 clamping the battery cell 12, it can also drive the first shaping component 31 to move along the first direction X to shape the first sub-bending segment 131, thereby improving work efficiency. Furthermore, by using a single drive unit for both the first shaping component 31 and the clamping assembly 21, the number of parts is reduced, thereby lowering costs. In addition, integrating the first shaping component 31 onto the clamping assembly 21 improves the integration between the two.

[0067] Optionally, the shaping mechanism 30 further includes a second shaping component 32 and a second driving component 34; the cell assembly equipment has a second direction Y perpendicular to the first direction X, the second driving component 34 is disposed on the base 42, and the second shaping component 32 is connected to the second driving component 34; the shaping part includes a second sub-shaping part 322 disposed on the second shaping component 32, the bending section includes a second sub-bending section 132, the second sub-shaping part 322 and the second sub-bending section 132 are disposed opposite to each other, and the second driving component 34 is used to drive the second sub-shaping part 322 to move along the second direction Y.

[0068] It should be noted that the second direction Y is Figure 1 The direction indicated by the Y-axis.

[0069] In this embodiment, the second driving member 34 is disposed on the base 42, and the second shaping member 32 is connected to the second driving member 34. The shaping part includes a second sub-shaping part 322 disposed on the second shaping member 32, and the bending section includes a second sub-bending section 132. The second sub-shaping part 322 and the second sub-bending section 132 are disposed opposite to each other. This allows the second driving member 34 to drive the second sub-shaping part 322 to move along the second direction Y, thereby aligning the second sub-shaping part 322 with the second sub-bending section 132 and preventing the second sub-bending section 132 from protruding from the housing 11 along the second direction Y, thus avoiding affecting subsequent assembly.
