Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of battery production related equipment, and in particular to a measuring device and a method thereof. BACKGROUND

[0002] To ensure the use performance and safety of the battery, the length, width, thickness, wire length and flexible circuit board length of the battery usually need to be inspected. There are three ways to inspect the size of the battery: one is to use a vernier caliper; two is to use a measuring tool; and three is to use an image instrument. However, compared with the vernier caliper or the image instrument, the measuring tool has higher inspection efficiency for inspecting the size of the battery, so that the production efficiency of the battery is greatly improved. Therefore, the measuring tool is generally used to inspect the size of the battery. However, when the measuring tool is used to inspect the size of the battery, the following problems exist:

[0003] 1. Single size measurement, poor size compatibility:

[0004] In general, the size inspection groove of the ordinary measuring tool is designed according to the external size of the battery. If the battery can be easily placed in the size inspection groove, it is a good product. If the battery cannot be placed in the size inspection groove, it is a defective product. Therefore, the ordinary measuring tool can only inspect the length and width of the battery, which leads to the fact that the ordinary measuring tool cannot inspect other sizes of the battery, and the size compatibility of the ordinary measuring device is poor.

[0005] 2. High inspection cost:

[0006] The ordinary measuring tool can only inspect the length and width of the battery, and cannot inspect other sizes of the battery. If other sizes of the battery need to be inspected, multiple measuring tools need to be designed and manufactured to inspect other sizes of the battery. Therefore, the inspection cost of the battery is high.

[0007] 3. Low inspection efficiency:

[0008] The ordinary measuring tool can only inspect the length and width of the battery. When other sizes of the battery need to be inspected, multiple measuring tools need to be prepared to inspect other sizes of the battery. However, during the size inspection of the battery, the corresponding measuring tool needs to be replaced according to the different sizes of the battery to be inspected, so that multiple sizes of the battery can be inspected. However, the size of the battery cannot be inspected during the replacement of the measuring tool, which leads to low inspection efficiency of the battery. SUMMARY

[0047] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0048] As Figures 1 to 6 ​​​As shown, a measuring device 10 in one embodiment includes a base 100 and a thickness measuring slider 200; the base 100 has a battery inspection slot 110 and a wire observation area 130. The battery inspection slot 110 is used to inspect the length and width of the battery 20, and the wire observation area 130 is used to inspect whether the length of the wire 201 of the battery 20 is qualified, so that the base 100 can inspect the length, width and wire 201 of the battery 20.

[0049] like Figures 1 to 6 As shown, in one embodiment, the thickness measuring slider 200 is slidably connected to the base 100. The thickness measuring slider 200 has a circuit board observation port 210. The thickness measuring slider 200 is used to check whether the thickness of the battery 20 is qualified. The circuit board observation port 210 is used to check whether the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified when the thickness measuring slider 200 checks that the thickness of the battery 20 is qualified. This allows the measuring device 10 to check the length, width, thickness of the battery 20, the length of the wire 201, and the length of the flexible circuit board 202. This makes the measuring device 10 not only compatible with multiple size inspections, but also has low inspection cost and high inspection efficiency.

[0050] In this embodiment, the measurement process of the measuring device 10 described above is as follows:

[0051] First, place the battery 20 to be inspected in the battery inspection slot 110, and straighten the wire 201 of the battery 20 towards the wire observation area 130. When placing the battery 20, the flexible circuit board 202 of the battery 20 should be exposed at the opening of the battery inspection slot 110. At the same time, the end of the battery 20 adjacent to the wire guide slot 120 should be tightly attached to the inner wall of the battery inspection slot 110, and the flexible circuit board 202 should be located on the path of the thickness measuring slider 200 relative to the base 100. Then, check whether the length and width of the battery 20 are qualified through the battery inspection slot 110. If the battery 20... If the battery 20 can be easily placed into the battery inspection slot 110, then the length and width of the battery 20 are considered to be qualified. Otherwise, the inspection of the battery 20 is stopped, and the battery 20 is considered to be defective. Then, when the length and width of the battery 20 are qualified, the thickness measuring slider 200 is pushed relative to the base 100 towards the battery inspection slot 110 to check whether the thickness of the battery 20 is qualified. If the thickness measuring slider 200 can be easily pushed above the battery 20, then the thickness of the battery 20 is considered to be qualified. Otherwise, the inspection of the battery 20 is stopped, and the battery 20 is considered to be defective.

[0052] Further, when the thickness of the battery 20 is qualified, the thickness measuring slider 200 is pushed to a predetermined position, and the length of the flexible circuit board 202 on the outer wall of the battery 20 is checked through the circuit board observation port 210. If the end point of the flexible circuit board 202 can be observed through the circuit board observation port 210, it is considered that the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified. Otherwise, the checking of the battery 20 is stopped, and the battery 20 is considered as a defective product. Then, when the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified, the length of the lead wire 201 of the battery 20 is checked through the lead wire observation area 130. If the end point of the lead wire 201 away from the end of the battery checking groove 110 is located in the lead wire observation area 130, it is considered that the length of the lead wire 201 is qualified. Otherwise, the checking of the battery 20 is stopped, and the battery 20 is considered as a defective product. Finally, the thickness measuring slider 200 is pushed back to the original position, and the battery 20 is taken out.

[0053] The measuring device 10 described above, since the base 100 is provided with the battery checking groove 110 and the lead wire observation area 130, the battery checking groove 110 is used to check the length and width of the battery 20, and the lead wire observation area 130 is used to check whether the length of the lead wire 201 of the battery 20 is qualified; the thickness measuring slider 200 is slidingly connected to the base 100, and the thickness measuring slider 200 is provided with the circuit board observation port 210, which is used to check whether the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified when the thickness of the battery 20 is qualified by the thickness measuring slider 200. Therefore, the measuring device 10 described above can check the length, width, thickness, length of the lead wire 201 and length of the flexible circuit board 202 of the battery 20, and can be compatible with multiple size checking.

[0054] Since the measuring device 10 described above can check the length, width, thickness, length of the lead wire 201 and length of the flexible circuit board 202 of the battery 20, compared with the ordinary measuring tool, the types of measuring tools needed to be replaced when checking the size of the battery 20 are reduced, not only the time waste caused by replacing different measuring tools during the checking process of the battery 20 is reduced, but also the types of measuring tools needed to be designed and manufactured are reduced, thereby the measuring device 10 described above can improve the checking efficiency of the battery 20, and can also reduce the checking cost of the battery 20.

[0055] As Figure 1 and Figure 6As shown in the drawings, in one embodiment, the measuring device 10 further comprises a positioning assembly 300 for positioning the thickness measuring slide 200 when the thickness measuring slide 200 has verified the thickness of the battery 20 to be qualified, so as to avoid the problem of low accuracy of the measuring device 10 in measuring the battery 20 due to the shaking of the battery 20 in the battery inspection groove 110.

[0056] As shown in the drawings, Figure 1 and Figure 6 As shown in the drawings, in one embodiment, the positioning assembly 300 comprises a first magnetic attraction member 310 and a second magnetic attraction member 320, the first magnetic attraction member 310 is arranged on the base 100, and the second magnetic attraction member 320 is arranged on the side of the thickness measuring slide 200 adjacent to the base 100, the first magnetic attraction member 310 is used to be magnetically connected to the second magnetic attraction member 320 when the thickness measuring slide 200 has verified the thickness of the battery 20 to be qualified, so that the first magnetic attraction member 310 and the second magnetic attraction member 320 limit the thickness measuring slide 200 to a predetermined position through magnetic attraction, avoiding the problem of sliding of the thickness measuring slide 200 relative to the base 100 during the inspection of the battery 20, so that the measuring device 10 does not need to fix the thickness measuring slide 200 at the predetermined position by hand, greatly improving the convenience of use of the above-mentioned measuring device 10, and more importantly, through the magnetic attraction connection design of the first magnetic attraction member 310 and the second magnetic attraction member 320, it is ensured that the thickness measuring slide 200 can be accurately slid relative to the base 100 to the position during the inspection, playing a reminding role of inspection in place, and improving the convenience of inspection.

[0057] In the embodiment, the positioning assembly 300 is a magnetic attraction assembly. It can be understood that in other embodiments, the positioning assembly 300 is not limited to the magnetic attraction assembly, but can also be other positioning modes for positioning the thickness measuring slide 200 relative to the base 100.

[0059] As shown in the drawings, Figure 6As shown in the drawings, in one of the embodiments, the base 100 comprises a first roller 150 and a second roller 160, both of which are rotatably connected to the limiting portion 140, and one side surface of the thickness measuring sliding block 200 slides in the bottom wall of the sliding guide channel 141, and both of the first roller 150 and the second roller 160 roll against the other side surface of the thickness measuring sliding block 200, so as to limit the thickness measuring sliding block 200 in the sliding guide channel 141, and meanwhile, the friction between the thickness measuring sliding block 200 and the first roller 150 and the second roller 160 can be reduced.

[0060] As shown in the drawings, Figure 1 and Figure 6 As shown in the drawings, in one of the embodiments, the end of the thickness measuring sliding block 200 away from the battery testing groove 110 is provided with a retreat-stop flange 220, which is used to abut against the limiting portion 140 when the thickness of the battery 20 is qualified by the thickness measuring sliding block 200, so as to position the thickness measuring sliding block 200 at the preset position.

[0062] As shown in the drawings, Figure 1 , Figure 2 and Figure 6 As shown in the drawings, in one of the embodiments, the push abutting surface 410 is parallel to the sliding direction of the thickness measuring sliding block 200, so as to make the sliding direction of the thickness measuring sliding block 200 parallel to the length direction of the flexible circuit board 202 of the battery 20, and thus the thickness measuring sliding block 200 can more accurately test whether the flexible circuit board 202 is qualified.

[0063] As shown in the drawings, Figure 6 As shown in the drawings, in one of the embodiments, the resilient push block 400 comprises a resilient member (not shown in the drawings) and a sliding block 420, one end of the resilient member is arranged in the sliding groove 170, and the other end of the resilient member is connected to the end of the sliding block 420 away from the push abutting surface 410, so as to push the sliding block 420 to slide towards the battery testing groove 110.

[0086] As shown in S109, if the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified, the length of the lead wire 201 of the battery 20 is inspected by the lead wire observation area 130. Figure 1 Figure 2 Figure 10 As shown in S109, if the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified, the length of the lead wire 201 of the battery 20 is inspected by the lead wire observation area 130.

[0087] ​​​​​​In the embodiment, if the length of the flexible circuit board 202 of the outer wall of the battery 20 is qualified, the length of the wire 201 of the battery 20 is checked through the wire-out observation area 130, so that the length of the wire 201 of the battery 20 is checked. Further, the step of checking the length of the wire 201 of the battery 20 through the wire-out observation area 130 is specifically that the wire 201 of the battery 20 is straightened along the guiding direction of the wire guiding groove 120, and then the length of the wire 201 of the battery 20 is checked through the wire-out observation area 130, so as to avoid the error of the test result caused by the wire 201 of the battery 20 not being straightened.

[0088] As shown in S111, the thickness measuring slider 200 is pushed to reset, and the battery 20 is taken out. Figure 1 Figure 10 As shown in S111, the thickness measuring slider 200 is pushed to reset, and the battery 20 is taken out.

[0089] In the embodiment, the thickness measuring slider 200 is pushed to reset, and the battery 20 is taken out, which facilitates the test of the next battery 20.

[0090] The above measurement method is specifically that the battery 20 to be tested is placed in the battery test groove 110, and the wire 201 of the battery 20 is straightened towards the wire-out observation area 130. When the battery 20 is placed, the flexible circuit board 202 of the battery 20 should be exposed to the groove of the battery test groove 110, and the end of the battery 20 adjacent to the wire guiding groove 120 should be close to the inner wall of the battery test groove 110, and the flexible circuit board 202 should be located on the path of the thickness measuring slider 200 sliding relative to the base 100. Then, the length and width of the battery 20 are checked through the battery test groove 110. If the battery 20 can be easily placed into the battery test groove 110, it is considered that the length and width of the battery 20 are qualified. Otherwise, the test of the battery 20 is stopped, and the battery 20 is considered as a defective product. Then, when the length and width of the battery 20 are qualified, the thickness measuring slider 200 is pushed to slide relative to the base 100 towards the battery test groove 110, so as to check whether the thickness of the battery 20 is qualified. If the thickness measuring slider 200 can be easily pushed above the battery 20, it is considered that the thickness of the battery 20 is qualified. Otherwise, the test of the battery 20 is stopped, and the battery 20 is considered as a defective product.

[0091] ​Further, when the thickness of the battery 20 is qualified, the thickness measuring slider 200 is pushed to a predetermined position, and whether the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified is checked through the circuit board observation port 210, if the end point of the flexible circuit board 202 can be observed through the circuit board observation port 210, it is considered that the length of the flexible circuit board 202 of the battery 20 is qualified, otherwise the inspection of the battery 20 is stopped, and the battery 20 is considered as a defective product; then, when the length of the flexible circuit board 202 on the outer wall of the battery 20 is qualified, whether the length of the lead 201 of the battery 20 is qualified is checked through the lead observation area 130, if the end point of the lead 201 away from the end of the battery inspection groove 110 is located in the lead observation area 130, it is considered that the length of the lead 201 is qualified, otherwise the inspection of the battery 20 is stopped, and the battery 20 is considered as a defective product; finally, the thickness measuring slider 200 is pushed to reset, and the battery 20 is taken out.

[0092] As shown in Figure 1 and Figure 10 , in one embodiment, before the step S101 of placing the battery 20 to be inspected in the battery inspection groove 110 and placing the lead 201 of the battery 20 into the lead guide groove 120, the measuring method further comprises:

[0093] As shown in Figure 10 , S98, the elastic push block 400 is installed in the sliding groove 170.

[0094] Further, the step of placing the battery 20 to be inspected in the battery inspection groove 110 is specifically:

[0095] The battery 20 to be inspected is placed in the battery inspection groove 110, and the push abutting surface 410 is used for elastically abutting to one side wall of the battery 20, so that the other side wall of the battery 20 is tightly attached to the inner wall of the battery inspection groove 110, avoiding the problem that the length direction of the circuit board observation port 210 and the flexible circuit board 202 can not be reliably aligned due to the gap between the battery 20 placed in the battery inspection groove 110 and the groove wall of the battery inspection groove 110, so that the length direction of the circuit board observation port 210 and the flexible circuit board 202 can be reliably aligned, and the inspection accuracy of the lead 201 and the flexible circuit board 202 of the battery 20 is improved.

[0096] As shown in Figure 1 , further, the step of taking out the battery 20 is specifically: pushing the elastic push block 400 away from the battery inspection groove 110, and taking out the battery 20.

[0097] It should be noted that the thickness of the battery 20 is actually the sum of the thickness of the battery 20 itself and the thickness of the flexible circuit board 202.

[0098] Compared with the prior art, the present disclosure includes but is not limited to the following advantages:

[0099] 1. The above measuring method, since the base 100 is provided with a battery inspection groove 110 and an outgoing line observation area 130, the battery inspection groove 110 is used to inspect the length and width of the battery 20, and the outgoing line observation area 130 is used to inspect whether the length of the lead wire 201 of the battery 20 is qualified; the thickness measuring slider 200 is slidingly connected to the base 100, and the thickness measuring slider 200 is provided with a circuit board observation port 210, the thickness measuring slider 200 is used to inspect whether the thickness of the battery 20 is qualified, and the circuit board observation port 210 is used to inspect whether the length of the flexible circuit board 202 of the outer wall of the battery 20 is qualified when the thickness measuring slider 200 inspects that the thickness of the battery 20 is qualified, so that the above measuring method can inspect the length, width, thickness, lead wire 201 length and flexible circuit board 202 length of the battery 20, and the above measuring method can be compatible with multiple size inspections.

[0100] 2. Since the above measuring method can inspect the length, width, thickness, lead wire 201 length and flexible circuit board 202 length of the battery 20, compared with ordinary measuring tools, the types of measuring tools required to be replaced when the above measuring method inspects the size of the battery 20 are reduced, not only the time waste caused by replacing different measuring tools during the inspection process of the above measuring method is reduced, but also the types of measuring tools required to be designed and manufactured are reduced, thereby the above measuring method can improve the inspection efficiency of the battery 20, and also can reduce the inspection cost of the battery 20.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which are within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
