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 Art

[0002] In order to ensure the performance and safety of the battery, it is usually necessary to inspect the length, width, thickness, wire length and flexible circuit board length of the battery. There are three ways to inspect the battery size: 1. Use a vernier caliper; 2. Use a measuring tool; 3. Use an imager. However, compared with using a vernier caliper or an imager to inspect the battery size, using a measuring tool to inspect the battery size has a higher inspection efficiency, which greatly improves the battery production efficiency. Therefore, a measuring tool is generally used to inspect the battery size. Among them, when using a measuring tool to inspect the battery size, there are the following problems:

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

[0004] In ordinary measuring tools, the size inspection slot is usually designed according to the external dimensions of the battery. If the battery can be easily placed in the size inspection slot, it is a good product. If the battery is difficult to place in the size inspection slot, it is a defective product. As a result, ordinary measuring tools can only inspect the length and width of the battery, which makes it impossible for ordinary measuring tools to inspect other dimensions of the battery, resulting in poor size compatibility of ordinary measuring devices.

[0005] 2. High inspection cost:

[0006] Ordinary measuring tools can only inspect the length and width of the battery and are not compatible with inspecting other battery sizes. If other battery sizes need to be inspected, multiple measuring tools need to be designed and manufactured to inspect other battery sizes, resulting in higher battery inspection costs.

[0007] 3. Low inspection efficiency:

[0008] Ordinary measuring tools can only inspect the length and width of the battery. When other dimensions of the battery need to be inspected, multiple measuring tools need to be prepared to inspect the other dimensions of the battery. However, during the battery size inspection process, the corresponding measuring tools need to be replaced according to the different inspection dimensions of the battery to inspect multiple dimensions of the battery. However, during the replacement of the measuring tools, the battery size cannot be inspected, which makes the battery inspection efficiency low. Summary of the invention

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

[0048] like Figures 1 to 6As shown, a measuring device 10 of an embodiment includes a base 100 and a thickness measuring slider 200; the base 100 is provided with a battery inspection slot 110, and the base 100 is provided with 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 of the battery 20 and the length of the wire 201.

[0049] like Figures 1 to 6 As shown, in one embodiment, the thickness measuring slider 200 is slidably 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 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, so that the above-mentioned measuring device 10 can check the length, width, thickness of the battery 20, the length of the wire 201 and the length of the flexible circuit board 202, so that the above-mentioned measuring device 10 is not only compatible with multiple size inspections, but also has a low inspection cost and a high inspection efficiency.

[0050] In this embodiment, the measurement process of the above-mentioned measuring device 10 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 toward the wire observation area 130. When placing the battery 20, the flexible circuit board 202 of the battery 20 should be exposed at the notch of the battery inspection slot 110, and the end of the battery 20 adjacent to the wire guide slot 120 should be close to the inner wall of the battery inspection slot 110, and the flexible circuit board 202 should be located on the path where the thickness measuring slider 200 slides relative to the base 100; then, the length and width of the battery 20 are inspected through the battery inspection slot 110 to see if they are qualified. If the battery 2 0 can be easily put into the battery inspection slot 110, it is considered that the length and width of the battery 20 are 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 to slide toward 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 to the top of the battery 20, it is considered that the thickness of the battery 20 is 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 of the outer wall of the battery 20 is checked through the circuit board observation port 210 to see if it is qualified. 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 to be defective. Then, when 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 outlet observation area 130 to see if it is qualified. If the end point of one end of the wire 201 away from the battery inspection slot 110 is located in the wire outlet observation area 130, it is considered that the length of the wire 201 is qualified. Otherwise, the inspection of the battery 20 is stopped and the battery 20 is considered to be defective. Finally, the thickness measuring slider 200 is pushed to reset and the battery 20 is taken out.

[0053] The above-mentioned measuring device 10 has a battery inspection slot 110 on the base 100, and a wire observation area 130 on the base 100. 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; the thickness measuring slider 200 is slidably connected to the base 100, and the thickness measuring slider 200 has 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 on 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-mentioned measuring device 10 can inspect the length, width, thickness, length of the wire 201 and length of the flexible circuit board 202 of the battery 20, so that the above-mentioned measuring device 10 can be compatible with multiple size inspections.

[0054] Since the above-mentioned measuring device 10 can inspect the length, width, thickness, length of the wire 201 and the length of the flexible circuit board 202 of the battery 20, compared with ordinary measuring tools, the above-mentioned measuring device 10 reduces the types of measuring tools that need to be replaced when inspecting the size of the battery 20. Not only does it reduce the time waste caused by replacing different measuring tools during the inspection of the battery 20 by the above-mentioned measuring device 10, but it also reduces the types of measuring tools that need to be designed and manufactured, thereby enabling the above-mentioned measuring device 10 to improve the inspection efficiency of the battery 20 and reduce the inspection cost of the battery 20.

[0055] like Figure 1 and Figure 6As shown, in one embodiment, the measuring device 10 further includes a positioning assembly 300, and the positioning assembly 300 is used to position the measuring slider 420 when the thickness measuring slider 200 detects that the thickness of the battery 20 is 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 slot 110 when the size of the battery 20 is inspected.

[0056] like Figure 1 and Figure 6 As shown, in one of the embodiments, the positioning assembly 300 includes a first magnetic member 310 and a second magnetic member 320, the first magnetic member 310 is arranged on the base 100, and the second magnetic member 320 is arranged on a side of the thickness measuring slider 200 adjacent to the base 100, the first magnetic member 310 is used to be magnetically connected to the second magnetic member 320 when the thickness of the thickness measuring slider 200 is qualified when inspecting the thickness of the battery 20, so that the first magnetic member 310 and the second magnetic member 320 limit the thickness measuring slider 200 to a predetermined position through magnetic attraction, avoiding the problem of the thickness measuring slider 200 sliding 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 slider 200 at the preset position by hand, which greatly improves the convenience of use of the above-mentioned measuring device 10, and more importantly, through the magnetic connection design of the first magnetic member 310 and the second magnetic member 320, it is ensured that the thickness measuring slider 200 can be accurately slid into place relative to the base 100 during the inspection, which serves as a reminder that the inspection is in place and improves the convenience of the inspection.

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

[0060] like Figure 1 and Figure 6 As shown, in one embodiment, a stop flange 220 is protruded from one end of the thickness measuring slider 200 away from the battery inspection slot 110. The stop flange 220 is used to abut against the limiting portion 140 when the thickness measuring slider 200 inspects the thickness of the battery 20 and finds that the thickness is qualified, so that the thickness measuring slider 200 can be positioned at a preset position.

[0062] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, the abutment surface 410 is pushed to be parallel to the sliding direction of the thickness measuring slider 200, so that the sliding direction of the thickness measuring slider 200 is parallel to the length direction of the flexible circuit board 202 of the battery 20, so that the thickness measuring slider 200 can more accurately check whether the flexible circuit board 202 is qualified.

[0063] like Figure 6 As shown, in one embodiment, the elastic push block 400 includes an elastic member (not shown) and a slider 420, one end of the elastic member is disposed in the sliding groove 170, and the other end of the elastic member is connected to an end of the slider 420 away from the pushing abutment surface 410 to push the slider 420 to slide toward the battery inspection slot 110.

In other embodiments, the pushing portion 421 and the abutting portion 422 are not limited to an integrally formed structure.

[0069] like Figure 6 As shown, further, the fixing member 500 includes a locking member, and the fixing member 500 is provided with a positioning hole. The first end of the locking member is passed through the positioning hole, and the second end of the locking member is fixed to the base 100 to facilitate the installation or removal of the fixing member 500.

[0084] like Figure 1 , Figure 2 and Fig.10 As shown, S107, if the thickness of the battery 20 is qualified, then 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 to see if it is qualified.

[0085] In this embodiment, if the length, width and thickness of the battery 20 are all qualified, that is, the length, width and thickness of the battery 20 pass the inspection, the thickness measuring slider 200 is pushed to slide to a predetermined position relative to the base 100 toward the battery inspection slot 110, and the length of the flexible circuit board 202 of the battery 20 is inspected through the circuit board observation port 210 to see if it is qualified.

[0086] like Figure 1 , Figure 2 and Fig.10 As shown, S109, if the length of the flexible circuit board 202 of the outer wall of the battery 20 is qualified, then the length of the wire 201 of the battery 20 is checked through the wire observation area 130 to see if it is qualified.

[0087] In this 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 observation area 130 to check whether the length of the wire 201 of the battery 20 is qualified. Further, the step of checking whether the length of the wire 201 of the battery 20 is qualified through the wire observation area 130 is specifically: straighten the wire 201 of the battery 20 along the guide direction of the wire guide groove 120, and then check whether the length of the wire 201 of the battery 20 is qualified through the wire observation area 130, so as to avoid the wire 201 of the battery 20 not being straightened and causing the inspection result to be wrong.

[0088] like Figure 1 and Fig.10 As shown, S111, the thickness measuring slider 200 is pushed to reset, and the battery 20 is removed.

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

[0090] In the above-mentioned measuring method, first, the battery 20 to be inspected is placed in the battery inspection slot 110, and the wire 201 of the battery 20 is straightened toward the wire observation area 130. When the battery 20 is placed, the flexible circuit board 202 of the battery 20 should be exposed in the notch of the battery inspection slot 110, and at the same time, one end of the battery 20 adjacent to the wire guide slot 120 should be close to the inner wall of the battery inspection slot 110, and the flexible circuit board 202 should be located on the path where the thickness measuring slider 200 slides relative to the base 100; then, the length and width of the battery 20 are inspected through the battery inspection slot 110 to see if they are qualified. If the battery 20 can be easily placed into the battery inspection slot 110, it is considered that the length and width of the battery 20 are 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 to slide relative to the base 100 toward 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 to the top of the battery 20, it is considered that the thickness of the battery 20 is qualified, otherwise the inspection of the battery 20 is stopped and the battery 20 is considered to be defective.

[0091] 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 of the outer wall of the battery 20 is checked through the circuit board observation port 210 to see if it is qualified. 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 to be defective. Then, when 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 to see if it is qualified. If the end point of one end of the wire 201 away from the battery inspection slot 110 is located in the wire-out observation area 130, it is considered that the length of the wire 201 is qualified. Otherwise, the inspection of the battery 20 is stopped and the battery 20 is considered to be defective. Finally, the thickness measuring slider 200 is pushed to reset and the battery 20 is taken out.

[0092] like Figure 1 and Fig.10 As shown, in one embodiment, before step S101 of placing the battery 20 to be inspected in the battery inspection slot 110 and placing and guiding the wire 201 of the battery 20 into the wire guide slot 120, the measuring method further includes:

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

[0094] Furthermore, the steps of placing the battery 20 to be inspected in the battery inspection slot 110 are specifically as follows:

[0095] The battery 20 to be inspected is placed in the battery inspection slot 110, and the pushing abutment surface 410 is used to elastically abut against one side wall of the battery 20, so that the other side wall of the battery 20 is close to the inner wall of the battery inspection slot 110, thereby avoiding the problem of the circuit board observation port 210 and the flexible circuit board 202 being reliably aligned in the length direction due to the gap between the battery 20 and the slot wall of the battery inspection slot 110 when the battery 20 is placed in the battery inspection slot 110. The circuit board observation port 210 and the flexible circuit board 202 are reliably aligned in the length direction, thereby improving the inspection accuracy of the wire 201 of the battery 20 and the flexible circuit board 202.

[0096] like Figure 1 As shown, further, the step of taking out the battery 20 is specifically as follows: pushing the elastic push block 400 in a direction away from the battery inspection slot 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 printed circuit board 202 .

[0098] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0099] 1. In the above-mentioned measuring method, since the base 100 is provided with a battery inspection slot 110, and the base 100 is provided with 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; the thickness measuring slider 200 is slidably connected to the base 100, and the thickness measuring slider 200 is provided with a circuit board observation port 210, and 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-mentioned measuring method can inspect the length, width, thickness of the battery 20, the length of the wire 201 and the length of the flexible circuit board 202, so that the above-mentioned measuring method can be compatible with multiple size inspections.

[0100] 2. Since the above-mentioned measuring method can inspect the length, width, thickness of the battery 20, the length of the wire 201 and the length of the flexible circuit board 202, compared with ordinary measuring tools, the above-mentioned measuring method reduces the types of measuring tools that need to be replaced when inspecting the size of the battery 20. This not only reduces the time waste caused by replacing different measuring tools during the inspection of the battery 20, but also reduces the types of measuring tools that need to be designed and manufactured, thereby enabling the above-mentioned measuring method to improve the inspection efficiency of the battery 20 and reduce the inspection cost of the battery 20.

[0101] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
