Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a battery cell size detection die, which comprises a die body 1 and a battery cell cover plate 2, wherein a first groove 11 for placing a battery cell is formed in the die body 1, and the battery cell cover plate 2 is matched with the first groove 11.

Further, as shown in fig. 2, 3, and 4, cell cover plate locking grooves 12 are disposed on the inner walls of the left and right sides of the mold body 1, and the lower bottom edges of the cell cover plate locking grooves 12 are higher than the bottom surface of the first groove 11.

Further, the left and right sides of the die body 1 are provided with first notches 13 at positions corresponding to the cell cover plate clamping grooves 12 and extend downwards to the bottom of the die body 1.

Further, a second notch 14 is arranged at a position, corresponding to the first notch 13, at the bottom of the first groove 11, and the second notch 14 extends horizontally inwards and is communicated with the bottom surface of the first groove 11; the first notch 13 is larger than the second notch 14 in size (length, width and depth), so that the battery cell can be conveniently grabbed by hands; the first notch 13 and the second notch 14 may be of any shape; the depth of the cell cover plate clamping groove 12 can be higher or lower than the size of the cell, but the depth needs to be lower than the minimum thickness of the pressed cell.

Further, as shown in fig. 2 and 3, a fixing block 15 is arranged in the die body 1 along a long side thereof, and at least two second grooves 16 for placing battery cell tabs are arranged on one side of the fixing block 15 close to the first groove 11; the number of the second grooves 16 may be determined according to the number of the cell tabs.

Further, as shown in fig. 5, the upper surface of the fixing block 15 is provided with first graduation lines 151, and the first graduation lines 151 extend into the second groove 16.

further, as shown in fig. 6, a side of the first groove 11 opposite to the fixed block 15 is provided with a second scale line 111.

further, the vertical distance from the zero scale mark in the second scale marks 111 to the bottom of the first groove 11 is the same as the thickness of the cell cover plate 2; the zero graduation line in the second graduation lines 111 is not level with the bottom surface of the first groove 11, but has a certain distance, and the distance is determined by the thickness of the cover plate; so, when measuring electric core thickness behind 2 piezoelectric cores of electric core apron 3, the number of degrees of electric core apron 2 top edge on the scale is electric core actual thickness promptly to the scale precision can be according to actual requirement and etch.

Further, as shown in fig. 8, the upper end of the cell cover plate 2 is provided with a handrail 21, so that the cell cover plate 2 is convenient for an operator to take and place; the weight and size of the cell cover plate 2 may be changed according to specific measurement requirements and the size of the cell 3.

The specific operation process of the cell size detection mold (as shown in fig. 1, 7 and 8) of the invention is as follows: put into the first recess 11 in the mould body 1 with coiling back electric core 3, if electric core 3 can normally put into first recess 11, then show that the length of electric core 3, width and utmost point ear all will go the within range at the technology, put into the mould with electric core apron 2 simultaneously, push down electric core 3, and read electric core 3's height through second scale mark 111, simultaneously, read other required sizes such as the left and right margins, utmost point ear centre-to-centre spacing of electric core 3 through first scale mark 151, then accomplish whole measurement process.

The battery cell size detection die provided by the invention can simplify the measurement process and improve the working efficiency and the measurement accuracy of staff; the battery core cover plate 2 with fixed weight can avoid operation errors caused by different pressures when the battery core 3 is manually pressed for thickness measurement; when the electric core cover plate 2 presses the electric core 3, the staff can timely and effectively read the thickness of the electric core 3 according to the second scale mark 111, so that the efficiency of manual testing can be improved, and the error of manual measurement can be reduced (the measurement tool is not perpendicular to the electric core, and the zero scale mark is not on the same horizontal line with the bottom of the electric core, which can cause the measurement thickness of the electric core to be higher); the size of the first groove 11 in the die body 1 can be designed according to the maximum length and width size allowed by the battery cell 3 and the maximum offset size of the battery cell tab, so that whether the size of the battery cell 3 is within the process requirement range can be determined timely and effectively; first scale mark 151 divide into interior outer scale, and numerical value both sides are zero on the interior scale, and the center is the biggest, and so design can read left side apart from (the distance of left utmost point ear edge or utmost point ear center to electric core left edge), right side apart from (the distance of right utmost point ear edge or utmost point ear center to electric core right edge) simultaneously, and numerical value is from little to big on the outer scale, measurable specific electric core width and utmost point ear center distance.

The invention has simple structure and simple operation, effectively simplifies the measuring process, improves the measuring efficiency, and simultaneously improves the working efficiency and the measuring accuracy of the staff.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
