Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing equipment, in particular to a battery core size detection device. Background Art

[0002] In today's fast-growing electronic product market, battery cells are an indispensable component of electronic products, and their quality directly affects the performance and service life of the products. Among them, the dimensional accuracy of the battery cells, as an important indicator of quality, has a significant impact on the stability and reliability of the product. Traditional battery cell size measurement methods mainly rely on manual operations, such as using calipers and other tools for size measurement. However, manual measurement is inefficient. In a mass production environment, although the measurement time of a single battery cell is not long, it will accumulate to become a time cost that cannot be ignored. This is obviously a huge waste of efficiency for modern production lines that pursue efficiency.

[0003] Secondly, the accuracy and reliability of manual measurement are difficult to guarantee. Different measurement personnel have different working experiences, and their operation methods and strengths may vary. The existence of these human factors may lead to large errors in the measurement results.

[0004] In order to solve the above problems, some automated measurement solutions have been proposed in the technical field. For example, by using automated equipment instead of manual measurement, the efficiency and accuracy of measurement can be improved. Patent authorization number CN215177531U proposes a battery cell size detection mechanism, which realizes the automated measurement of battery cell size by integrating a mobile platform, a first detection device and a second detection device. In this way, the errors caused by manual operation can be effectively reduced, and production efficiency and product quality can be improved.

[0005] Although it realizes the automatic measurement of battery cell size, due to the fixed position of the detection device, when encountering special batteries that exceed the preset size range, the detection mechanism cannot perform effective measurement or adjustment, and thus cannot provide immediate and accurate feedback on oversized batteries. This limits the application scenarios of the detection mechanism to a certain extent and reduces its flexibility and adaptability in actual production.

[0006] Therefore, how to measure battery cells of different sizes and improve the applicability of battery cell size detection devices has become a technical problem that needs to be solved urgently. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0028] like Figure 1 to Figure 2 As shown, in order to achieve the above purpose, the utility model proposes a battery cell size detection device, comprising:

[0029] A first guide rail 11;

[0030] A support rod 20, a first end of which is slidably connected to the first guide rail 11 and can reciprocate along the length direction of the first guide rail 11;

[0031] A telescopic member 50, a first end of which is connected to the support rod 20, and when the telescopic member 50 is in a working state, the length direction of the telescopic member 50 is perpendicular to the length direction of the support rod 20; and

[0032] The detection member 60 is used to detect the size of the battery cell. The detection member 60 is connected to the second end of the telescopic member 50 and can move with the telescopic member 50 to adapt to battery cells of different sizes.

[0033] Specifically, the first guide rail 11 is made of stainless steel or aluminum alloy with strong wear resistance to ensure the stability and accuracy of sliding. It is conceivable that the surface of the first guide rail 11 can be hardened. The first guide rail 11 ensures that the support rod 20 can move smoothly along its length direction, thereby improving the accuracy of detection.

[0034] The support rod 20 is made of stainless steel or aluminum alloy to ensure that the support rod 20 has sufficient strength and rigidity to carry the telescopic member 50 and the detection member 60. One end of the support rod 20 is equipped with a limit portion 21, which is slidably connected to the first guide rail 11 to ensure that it can reciprocate smoothly on the guide rail without unnecessary lateral deviation.

[0035] The telescopic member 50 is made of metal materials such as carbon steel or special alloys to ensure stability and durability during the telescopic process. It is conceivable that the telescopic member 50 can be completed by using components such as a telescopic cylinder and a telescopic screw rod, or it can be implemented by using a plurality of coaxially sleeved tubes. When extension is required, the corresponding tube can be extended. When contraction is required, the corresponding tube only needs to be retracted to complete the contraction. The telescopic member 50 can be connected to the support rod 20 in an articulated manner, or it can be connected in a fixed connection manner, such as welding.

[0036] The detection member 60 is used to measure the size of the battery cell, and the detection member 60 includes a sensor, a scanning device or other measurement modules. The detection member 60 is connected to the second end of the telescopic member 50. By adjusting the telescopic member 50, the detection member 60 can perform size detection on battery cells of different sizes, thereby improving the application range of the battery cell size detection device.

[0037] By adopting the above technical solution, the first guide rail 11 ensures that the support rod 20 can reciprocate smoothly, thereby improving the movement accuracy and measurement stability of the entire device. By adjusting the telescopic adjustment to adapt to different sizes of battery cells, the application range of the device is increased and the requirements for different battery size detection can be met. At the same time, the detection member 60 can accurately measure the size of the battery cell, effectively improving the accuracy and reliability of the quality control of the battery cell production.

[0038] In one embodiment of the present application, a U-shaped groove is provided on the first guide rail 11, and limiting protrusions are respectively provided on the two free ends of the U-shaped groove, and the distance between the two limiting protrusions is smaller than the distance between the two free ends of the U-shaped groove.

[0039] Specifically, a U-shaped groove is provided on the first guide rail 11, and the U-shaped groove mainly guides and stabilizes the sliding of the support rod 20. Limiting protrusions are provided on the two free ends of the U-shaped groove, and the moving range of the support rod 20 is limited by the limiting protrusions to prevent it from leaving the guide rail during movement.

[0040] The limiting protrusion is made of the same or similar hard material as the guide rail, such as stainless steel or hard alloy, and is formed by machining or casting to ensure that its strength and wear resistance match the requirements of the guide rail. This allows the limiting protrusion to not only effectively prevent excessive movement of the support rod 20, but also withstand the wear caused by long-term repeated movement, thereby extending the service life of the entire device.

[0041] By adopting the above technical solution, not only the operating stability and accuracy of the equipment are improved through the limiting protrusion, but also a stable connection between the support rod 20 and the first guide rail 11 is ensured, thereby avoiding separation between the support rod 20 and the first guide rail 11.

[0042] In one embodiment of the present application, a limiting portion 21 is provided at the first end of the support rod 20, and the limiting portion 21 is slidably connected in the U-shaped groove. The distance between the two ends of the limiting portion 21 is greater than the distance between the two limiting protrusions, and the width of the support rod 20 is smaller than the distance between the two free ends of the U-shaped groove.

[0043] Specifically, the material used for the limit portion 21 is the same as that of the support rod 20, which ensures the durability and consistency of the entire system. The distance between the two ends of the limit portion 21 is greater than the distance between the two limit protrusions. Such a design not only ensures the stability of the support rod 20 during movement, preventing it from lateral swing or derailment at the movement limit, but also ensures that the support rod 20 can fully utilize the sliding space of the guide rail, thereby improving movement efficiency and measurement accuracy.

[0044] The adoption of the above technical solution can effectively prevent the support rod 20 from derailing during the movement, improve the stability and safety of the movement of the support rod 20, and provide a basis for subsequent size detection.

[0045] In one embodiment of the present application, it also includes a second guide rail 12 arranged opposite to the first guide rail 11, the length direction of the second guide rail 12 is parallel to the length direction of the first guide rail 11, and the second end of the support rod 20 is slidably connected to the second guide rail 12 and can reciprocate along the length direction of the second guide rail 12.

[0046] Specifically, a double-track guide system is formed by providing the second guide rail 12. The second guide rail 12 is arranged opposite to the first guide rail 11, and the length directions of the two are parallel. This parallel arrangement ensures the stability of the entire system and the accuracy of measurement.

[0047] The second end of the support rod 20 is slidably connected to the second guide rail 12. This connection not only allows the support rod 20 to reciprocate smoothly on the second guide rail 12, but also ensures that the support rod 20 maintains a constant distance and parallelism between the two guide rails.

[0048] By adopting the above technical solution, the use of a dual-track guide system greatly improves the adaptability of the device, and can more flexibly respond to the detection requirements of battery cells of different specifications and sizes. Whether it is a small-sized battery cell or a large-sized battery cell, the dual-track system can ensure the smooth and precise movement of the support rod 20, thereby making the entire detection process more efficient and quick.

[0049] In one embodiment of the present application, a connecting plate 30 is further provided between the support rod 20 and the telescopic member 50. The connecting plate 30 is slidably connected to the support rod 20 and can reciprocate along the length direction of the support rod 20. A threaded through hole is provided on the connecting plate 30, and a limit screw is provided in the threaded through hole for locking the connecting plate 30 on the support rod 20. The first end of the telescopic member 50 is connected to the connecting plate 30.

[0050] Specifically, a connecting plate 30 is provided between the support rod 20 and the telescopic member 50. The connecting plate 30 can reciprocate along the length direction of the support rod 20, so as to adjust the position of the connecting plate 30. A threaded through hole is provided on the connecting plate 30. When the connecting plate 30 moves to the specified position, the connecting plate 30 is fixed to the support rod 20 by a limit screw to achieve the fixation of the connecting plate 30. It can be imagined that the connecting plate 30 is preferably in the middle position of the support rod 20.

[0051] With the above technical solution, the threaded through hole and the limit screw design on the connecting plate allow the operator to accurately lock the connecting plate 30 at a specific position of the support rod 20, ensuring stability and reliability during the measurement process. This locking mechanism avoids measurement errors caused by device position errors, thereby ensuring the accuracy of the measurement results.

[0052] In one embodiment of the present application, a socket 40 is further provided between the telescopic member 50 and the connecting plate 30; the first end of the socket 40 is connected to the connecting plate 30, the second end of the socket 40 is provided with a through hole, the first end of the telescopic member 50 is provided with an assembly hole, and the screws pass through the assembly hole and the through hole in sequence to connect the telescopic member 50 to the socket 40.

[0053] With the above technical solution, the design of the holder 40 ensures the stability of the telescopic member 50 during use, reduces the error caused by loose connection, and thus improves the reliability of the entire system. At the same time, it is also convenient to store the telescopic member 50 when size identification is not required.

[0054] In one embodiment of the present application, the first end of the telescopic member 50 can rotate relative to the screw; a lug is provided on the end of the holder 40 close to the through hole, and the first end of the telescopic member 50 is provided with a recess matching the lug, and when the telescopic member 50 is rotated to the working position, the lug is engaged in the recess.

[0055] With the above technical solution, when the telescopic member 50 is rotated to the working position and the lug is engaged in the recess, a simple and effective locking mechanism is formed. This locking method ensures the stability between the telescopic member 50 and the holder 40 during use, reduces the measurement error that may be caused by position offset, and enhances the reliability of the entire device.

[0056] In an embodiment of the present application, the telescopic member 50 includes a first fixed rod, at least one telescopic rod is concentrically disposed inside the first fixed rod, and the detection member 60 is connected to an end of the telescopic rod with the smallest diameter away from the support rod 20 .

[0057] By adopting the above technical solution, the concentric telescopic rod design enables the overall structure to provide a larger telescopic range in the axial direction without occupying additional radial space.

[0058] In an embodiment of the present application, there are two telescopic rods.

[0059] In one embodiment of the present application, a lighting element 70 for supplementary light is further provided on one side of the detection element 60 .

[0060] By adopting the above technical solution, the size detection accuracy can be improved by providing an illumination element 70. The illumination element 70 in the present application can be infrared light or the like.

[0061] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
