Referring to fig. 1 and fig. 2, an embodiment of the present invention discloses a cell size measuring apparatus, where the cell size measuring apparatus 100 may be used to measure a width, a length, or a thickness of a cell, for example, to measure a width of the cell along a left-right direction in fig. 1. Specifically, this electric core size measurement equipment 100 includes base 1, measurement strake 2, measurement sighting rod 3 and electronic measurement ware 4, measurement strake 2 sets up in base 1, measurement sighting rod 3 sets up in base 1, and measurement sighting rod 3 can stretch out and draw back along the orientation or keep away from the direction of measurement strake, for example, measurement sighting rod 3 can stretch out and draw back along the left and right sides direction in fig. 1 to with measuring between strake 2 and forming the measurement region 300 that is used for measuring electric core 200, namely, form the measurement region 300 that is used for placing electric core 200 between measurement sighting rod 3 and the measurement strake 2, this electronic measurement ware 4 is connected with measurement sighting rod 3 electricity, thereby the width of electric core is confirmed to the flexible distance of accessible measurement sighting rod 3.

That is to say, the electric core size measuring equipment 100 that this application provided accessible sets up electronic measurement ware 4 and scalable connection in the survey sighting rod 3 of electronic measurement ware 4, when measuring electric core 200, the size of electric core is confirmed to the flexible distance of this electronic measurement ware 4 accessible survey sighting rod 3, reduces artifical participation degree to be favorable to improving the measurement precision and the measurement efficiency of electric core width, in order to satisfy the electric core design high accuracy requirement that promotes day by day. Moreover, in the battery cell size measuring device 100 provided by the application, the electronic measurer 4 is mainly used for determining the width of the battery cell through the telescopic distance of the measuring marker post 3, the operation is simple, the measurement is accurate and efficient, and the measurement efficiency of the battery cell width can be remarkably improved.

Illustratively, the base 1 may be an elongated block, such as a rectangular block, a square block, an oval block, or other regular block structure. It is understood that in other embodiments, the base 1 may have an irregular block structure, which is not limited in this embodiment.

In some embodiments, the electronic measuring device 4 may be an electronic measuring device with a display screen, for example, an electronic display meter, when measuring the battery cell 200, the electronic measuring device 4 may determine the size of the battery cell by measuring the telescopic distance of the measuring rod 3, and display the size on the display screen of the electronic measuring device 4, so that a measurer can directly read the value on the display screen of the electronic measuring device 4, can quickly know the width of the battery cell, and reduce an error of manually reading scales on the vernier caliper by visual observation, thereby being beneficial to further improving the measurement accuracy and the measurement efficiency of the battery cell width.

It can be understood that, in other embodiments, the electronic measuring device 4 may also be an electronic measuring device without a display screen, then the electronic measuring device 4 at this time may be electrically connected to the display device, when measuring the battery cell 200, the electronic measuring device 4 may determine the size of the battery cell through the telescopic distance of the measuring marker post 3, and display the size on the display screen of the display device, so that a measurer may directly read the value on the display screen of the display device, and can also quickly know the width of the battery cell, reduce the error of reading the scale on the vernier caliper by manual visual observation, and further facilitate further improving the measurement accuracy and measurement efficiency of the battery cell width. The electronic measuring device 4 may be a hall sensor or a pressure sensor.

The following description will exemplify the operation flow of measuring the cell width by using the cell size measuring apparatus 100, taking the electronic measuring device 4 as an electronic display meter as an example: the method includes the steps of zeroing a numerical value on a display screen of the electronic measurer 4, then contracting the measuring pole 3 to increase the width of the measuring area 300, so as to place the battery cell 200 into the measuring area 300, then extending the measuring pole 3 and enabling the measuring pole 3 to abut against the battery cell 200, and finally reading the numerical value on the display screen of the electronic measurer 4, so that the width of the battery cell 200 is measured.

In order to ensure the measurement accuracy and the measurement consistency, the standard cell may be used for calibration before measuring the width of the cell 200, that is, the standard cell may be used for calibration before measuring the width of the cell 200, specifically, after the standard cell is placed in the measurement area 300, the electronic measurement device 4 is calibrated and set, so as to adjust the value on the display screen of the electronic measurement device 4 to the width value of the standard cell. For example, assuming that the width of the standard cell is 50mm, after the standard cell is placed in the measurement area 300, the electronic measuring device 4 is calibrated to adjust the value on the display screen of the electronic measuring device 4 to 50mm, and then the width of the cell 200 is measured. Assuming that the measuring pole 3 extends 2mm in the right direction in fig. 1 after the battery cell 200 is placed in the measuring area 300, the value on the display screen of the electronic measuring device 4 will be displayed as 48mm, that is, the width of the battery cell 200 is 48mm, so as to complete the measurement of the width of the battery cell.

Considering that, during measurement, one end of the measurement target rod 3 facing the measurement edge bar 2 needs to abut against the battery cell 200, and in order to avoid that the area of the end surface of the measurement target rod 3 facing the end of the measurement edge bar 2 is too small to damage the battery cell 200, as shown in fig. 3, one end of the measurement target rod 3 facing the measurement edge bar may be provided with an abutting portion 31, the abutting portion 31 has an abutting surface 311 for abutting against the battery cell, the abutting surface 311 and the measurement edge bar 2 form the aforementioned measurement region 300, and the abutting surface 311 has an area of S1, a cross-sectional area of the measurement target rod 3, which is cut by a plane perpendicular to an axis of the measurement target rod 3, is S2, and S1 is greater than S2, that is, the area of the abutting surface 311 is greater than the cross-sectional area of the measurement target rod 3, which is cut by a plane perpendicular to the axis of the measurement target rod 3, so that the end surface of the measurement target rod 3 facing the end of the measurement edge bar 2 has a larger area to contact with the battery cell 200, damage to the cell 200 is avoided.

In some embodiments, as shown in fig. 1, fig. 2 and fig. 3, the measuring post 3 may include a fixed rod 32 and a movable rod 33, the fixed rod 32 is connected to the electronic measuring device 4, the movable rod 33 is movably connected to the fixed rod 32, the movable rod 33 is provided with the aforementioned abutting portion 31, and the movable rod 33 can extend and retract in a direction toward or away from the measuring edge 2, for example, the movable rod 33 can extend and retract in a left-right direction in fig. 1, so that a measuring area 300 for placing the battery cell 200 is formed between the abutting surface 311 of the abutting portion 31 and the measuring edge 2, and then the electronic measuring device 4 can determine the width of the battery cell 200 by the extending and retracting distance of the movable rod 33 relative to the fixed rod 32.

Further, the fixed rod 32 and the movable rod 33 may be nested with each other to form a telescopic structure. For example, the fixed rod 32 may be a hollow rod-shaped structure, and the movable rod 33 may be a solid rod-shaped structure, the movable rod 33 is disposed through the fixed rod 32, and the movable rod 33 can extend and contract relative to the fixed rod 32 in a direction toward or away from the measuring edge 2. It can be seen that the diameter of the fixed lever 32 is greater than the diameter of the movable lever 33.

In order to realize that the movable rod 33 can be extended and retracted relative to the fixed rod 32 in its axial direction, as a first alternative embodiment, as shown in fig. 4 and (a) of fig. 5, one of the fixed rod 32 and the movable rod 33 is provided with an external thread, and the other of the fixed rod 32 and the movable rod 33 is provided with an internal thread, for example, in the embodiment shown in (a) of fig. 5, the inner surface of the fixed rod 32 is provided with an internal thread, and the outer peripheral surface of the movable rod 33 is provided with an external thread, and the internal thread and the external thread are spirally connected so as to enable the movable rod 33 to be extended and retracted in a direction toward or away from the measuring edge 2 when rotated, for example, the movable rod 33 can be extended and retracted in a left-right direction in (a) of fig. 5. That is, when the movable lever 33 is rotated clockwise, the movable lever 33 can be extended out of the fixed lever 32 in the right direction in fig. 5 (a) to reduce the width of the measurement area 300, and when the movable lever 33 is rotated counterclockwise, the movable lever 33 can be retracted into the inside of the fixed lever 32 in the right direction in fig. 5 (a) to increase the width of the measurement area 300. By adopting the design, the structure of the measuring marker post 3 is simpler, and the design cost is favorably reduced.

As a second alternative, as shown in fig. 4 and fig. 5 (b), an elastic member 41 is disposed inside the electronic measuring device 4, one end of the movable rod 33 can extend into the electronic measuring device 4 to connect with the elastic member 41, when the movable rod 33 moves relative to the fixed rod 32 in a direction away from the measuring edge 2 (e.g. in a leftward direction in fig. 5 (b)), the elastic member 41 is elastically deformed under the action of the movable rod 33, so that the elastic member 41 provides a force for moving the movable rod 33 in a direction toward the measuring edge 2 (e.g. in a rightward direction in fig. 5 (b)) when restoring the deformation, that is, when measuring the width of the battery cell 200, after zeroing, the measuring rod 3 needs to be contracted to increase the width of the measuring area 300 to place the battery cell 200 into the measuring area 300, specifically, so that the movable rod 33 retracts into the fixed rod 32 in a direction away from the measuring edge 2, in order to increase the width of measuring area 300, in order to put into measuring area 300 with electric core 200, in this process, movable rod 33 can act on elastic component 41 and make elastic component 41 take place elastic deformation, treat to loosen behind the movable rod 33, elastic component 41 can reply deformation in order to promote movable rod 33 along the direction removal of orientation measurement strake 2 to with electric core 200 butt, and in this process, electric measurer 4 accessible measures the flexible distance of sighting rod 3 and confirms the size of electric core 200, and show on electric measurer 4's display screen, thereby the numerical value on electric measurer 4's the display screen can directly read, alright learn the width of electric core fast.

The method mainly considers that the strength of manually using a vernier caliper to clamp the cell is difficult to control, so that the measurement accuracy of the cell width is low easily, and the requirement of increasing high precision of cell design cannot be met. By adopting the second alternative embodiment, the elastic component 41 can restore the deformation characteristic to push the movable rod 33 to move to abut against the battery cell 200 along the direction toward the measuring edge strip 2, and the movable rod 33 does not need to be manually moved to abut against the battery cell 200, so that more accurate battery cell width data can be obtained, and the accuracy and consistency of the battery cell width can be effectively improved.

The elastic member 41 may be a spring, a silica gel column, a rubber column, a plastic column, or a foam column.

In this embodiment, as shown in fig. 5 (b), the electronic measuring device 4 is further provided with a limit portion 42 inside, when the movable rod 33 moves relative to the fixed rod 32 in a direction away from the measuring edge 2 (e.g., in a leftward direction in fig. 5 (b)), one end of the movable rod 33 can abut against the limit portion 42 to limit a moving distance of the movable rod 33 relative to the fixed rod 32, that is, when one end of the movable rod 33 abuts against the limit portion 42, the movable rod 33 cannot move relative to the fixed rod 32, and the elastic member 41 cannot continue to be elastically deformed, so that it is possible to avoid a situation that the deformation amount of the elastic member 41 is too large to cause an elastic failure of the elastic member 41, and even the elastic member 41 may break, so as to ensure that the elastic member 41 can be normally used. The position-limiting portion 42 can be a position-limiting block, a position-limiting post, or a position-limiting plate.

In consideration of the fact that the cell width measuring device in the related art can only measure the width of one position of the cell, but cannot perform all-around width measurement on the cell, the measurement data may be inaccurate, so that misjudgment or missed judgment is easy to occur, the measurement efficiency is low, and the cell width measuring device can only be used for sampling inspection of products and cannot be used for cell width detection in large-scale production.

In order to overcome the above problem, in some embodiments, as shown in fig. 6, a slide rail 11 is disposed at a position of the base 1 between the electronic measuring device 4 and the measuring edge strip 2, and the cell size measuring apparatus 100 may further include a slider 5 slidably connected to the slide rail 11, the slider 5 can slide relative to the slide rail 11 along a first direction, the first direction is perpendicular to a stretching direction of the measuring target 3, for example, the slider 5 can slide relative to the slide rail 11 along a front-back direction in fig. 6, and the measuring target 3 is disposed through the slider 5, so that the measuring target 3 can move along the first direction under the driving of the slider 5 to abut against different portions of the cell 200, and thus widths of different portions of the cell can be measured, so as to perform omnibearing width measurement on the cell, and further improve accuracy of measured data. And, only need through the slider 5 that slides alright carry out omnidirectional width measurement to electric core, easy operation can reach quick measuring purpose, and measurement of efficiency is high.

Considering that the telescopic distance of the measuring target 3 is limited, and since the measuring target 3 is inserted into the sliding block 5, and the width of the measuring area 300 can be changed to place different types (different widths) of battery cells by changing the position of the sliding block 5 on the base 1, and the widths of the different types of battery cells can be measured, as an alternative embodiment, the battery cell size measuring apparatus 100 may further include a sliding rail plate 6, the sliding rail plate 6 is provided with the aforementioned sliding rail 11, and the sliding rail plate 6 is provided with a first connecting portion 61, the base 1 is provided with a plurality of second connecting portions 12, the plurality of second connecting portions 12 are arranged at intervals along the telescopic direction of the measuring target 3, for example, the plurality of second connecting portions 12 are arranged at intervals along the left-right direction in fig. 6, the first connecting portion 61 is detachably connected to any one of the second connecting portions 12, the position of the sliding rail 11 on the base 1 is changed, so that the position of the sliding block 5 on the base 1 can be changed, the width of the measuring area 300 is changed to place different types of battery cells, the width of the battery cells of different types is measured, and the applicability is higher.

For convenience of description, from the right to left direction in fig. 6, the plurality of sets of second connection portions may be defined as a first set of second connection portions, a second set of second connection portions, a third set of second connection portions, or a fourth set of second connection portions in sequence, where the first set of second connection portions is a set of second connection portions closest to the measuring edge 2, and the fourth set of second connection portions is a set of second connection portions farthest from the measuring edge 2.

It should be noted that, assuming that when the first connecting portion 61 of the sliding rail plate 6 is connected to the first group of second connecting portions, and a battery cell with a width of 45mm to 55mm can be measured, a standard battery cell with a width of 50mm needs to be placed in the measurement area 300, calibration setting is performed on the electronic measurement device 4 to adjust the value on the display screen of the electronic measurement device 4 to 50mm, and then the width of the battery cell 200 is measured. When the slide plate 6 is detached to connect the first connection portion 61 with the different second connection portion 12, for example, when the slide plate 6 is detached to connect the first connection portion 61 with the second group of second connection portions to measure the battery cell with the width of 55mm to 65mm, similarly, the standard battery cell with the width of 60mm needs to be placed in the measurement area 300, the electronic measurement device 4 needs to be calibrated to adjust the value on the display screen of the electronic measurement device 4 to 60mm, and then the width of the battery cell 200 needs to be measured.
