[0002] In order to detect the integrity of the battery sealing package, helium inspection is generally performed using helium inspection equipment. When the battery is subjected to helium inspection, the battery fixture is lifted up by a lifting mechanism until it fits with the upper cover plate, so that the battery fixture and the upper cover plate cooperate to form a closed helium inspection chamber.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] The utility model proposes an anti-error detection mechanism, which is applied to helium detection equipment. Figure 1 The anti-false detection mechanism 10 has the function of accurately detecting the in-place status of the battery on the battery fixture 30, effectively avoiding the phenomenon of empty inspection of the helium inspection equipment, and improving the production quality of the helium inspection battery.

[0028] Reference Figures 1 to 3 The anti-misdetection mechanism 10 includes two support members 1 and two in-situ detection components 2. The two support members 1 are arranged opposite to each other, and a discharge position 3 for placing the battery fixture 30 is formed between the two support members 1. The two in-situ detection components 2 are installed on the two support members 1 in a one-to-one correspondence. The installation heights of the two in-situ detection components 2 are the same. One of the two in-situ detection components 2 can emit light and the other can receive light. The two in-situ detection components 2 are used to detect the in-situ status of the battery on the battery fixture 30.

[0029] The in-place detection component 2 includes an in-place detection component 21 and a first anti-mis-blocking component 22. The first anti-mis-blocking component 22 is used to shield the in-place detection component 21. The first anti-mis-blocking component 22 is provided with a first light-transmitting area 2231. The first light-transmitting area 2231 is arranged corresponding to the light end of the in-place detection component 21. The first light-transmitting area 2231 allows light to pass through.

[0030] Based on the above-mentioned scheme, the in-place detection component 2 is blocked by the first anti-misblocking component 22, and light is allowed to pass through the first light-transmitting area 2231. Under the premise that the first anti-misblocking component 22 blocks most of the light, only a small amount of light is allowed to pass through the first light-transmitting area 2231, so that the in-place detection component 21 can normally receive light or the emitted light can pass through the first light-transmitting area 2231. To a certain extent, it can well avoid the problem of inaccurate detection of the battery's in-place status due to light interference caused by light scattering, thereby improving the accuracy of the battery's in-place status and avoiding the phenomenon of empty inspection of the helium detection mechanism.

[0031] During the inspection, the battery fixture 30 is lifted until the height of the battery is consistent with the height of the two in-place detection parts 21. One of the two in-place detection parts 21 is used to emit light, and the other is used to receive light. The emitted light passes through the corresponding first light-transmitting area 2231. If the battery is in place, the emitted light is blocked by the battery, and the other in-place detection part 21 cannot receive the light, then it is determined that the battery on the battery fixture 30 is in place; if the other in-place detection part 21 can receive the light normally, then it is determined that the battery on the battery fixture 30 is not in place.

[0032] It should be noted that the first anti-mis-blocking member 22 may be provided with a first light-transmitting hole to form a first light-transmitting area 2231. Part of the light may be allowed to pass through the first light-transmitting hole, which can effectively avoid light interference, so that the in-place detection member 21 used for receiving light among the two in-place detection members 21 can accurately receive light, thereby improving the accuracy of detecting the battery in-place state.

[0033] The first light-transmitting hole may be arranged in any shape such as square, circle, ellipse, trapezoid, triangle or irregular shape.

[0034] The first anti-mistake blocking member 22 may also be provided with a transparent portion to form a first light-transmitting area 2231. The first anti-mistake blocking member 22 is a transparent acrylic structure, and the surface of the first anti-mistake blocking member 22 is treated with an opaque coating, and the position of the optical end corresponding to the in-place detection member 21 is retained without coating treatment, so that the light-incoming area of ​​the first anti-mistake blocking member 22 can be reduced, thereby effectively avoiding light interference, so that the in-place detection member 21 can accurately receive light, and improve the detection accuracy of the battery in-place status.

[0035] Continue to refer to Figures 1 to 3The support member 1 is provided with a support portion 11 , and the anti-mistake detection mechanism 10 further includes a fastener (not shown in the figure), which is used to fix the first anti-mistake blocking member 22 on the support portion 11 , and the in-situ detection component 2 is connected to the first anti-mistake blocking member 22 .

[0036] Such arrangement enables the in-situ detection component 2 to be conveniently installed, so that the in-situ detection component 2 can be stably installed on the support member 1 .

[0037] The support portion 11 is penetrated by a long mounting hole 111 extending along the length direction of the support portion 11 itself. The fastener part is arranged in the long mounting hole 111. The fastener can move along the direction defined by the long mounting hole 111 to adjust the height position of the in-situ detection component 2.

[0038] In this way, the height position of the in-situ detection component 2 can be adjusted according to the on-site production environment to adapt to batteries of different lengths. It is suitable for in-situ status detection of batteries of different specifications and has wider applicability.

[0039] Continue to refer to Figures 1 to 3 The first anti-misblocking component 22 includes a mounting portion 221, a connecting portion 222 and a shielding portion 223. The mounting portion 221 is fixedly connected to a fastener, the mounting portion 221 and the shielding portion 223 are spaced apart, the connecting portion 222 is disposed between the mounting portion 221 and the shielding portion 223, one end of the connecting portion 222 is connected to the mounting portion 221, and the other end is connected to the shielding portion 223. The in-position detection component 21 is mounted on one side of the mounting portion 221 facing the shielding portion 223, and the shielding portion 223 and the connecting portion 222 are disposed at an angle.

[0040] With such arrangement, the mounting portion 221 , the connecting portion 222 and the shielding portion 223 can effectively avoid interference of light on the in-place detection member 21 , reduce the possibility of misdetection by the in-place detection member 21 , and improve the accuracy of the in-place detection member 21 in detecting the battery in-place status.

[0041] It can be understood that the first light-transmitting area 2231 is formed on the side wall of the shielding portion 223 .

[0042] The shielding portion 223 is vertically arranged with respect to the connecting portion 222. Such an arrangement is very beneficial for the in-situ detection member 21 to receive light, so as to better improve the accuracy of the in-situ detection member 21 in receiving light.

[0043] Continue to refer to Figures 1 to 3 The anti-misdetection mechanism 10 also includes two in-place detection components 4, which are respectively installed on the corresponding support members 1. The in-place detection components 4 are arranged above the in-place detection components 2 in the vertical direction. The two in-place detection components 4 are used to detect the in-place status of the battery on the battery fixture 30.

[0044] Such arrangement can detect the position of the battery on the battery fixture 30, effectively avoiding the phenomenon that the battery is damaged due to the cylinder 20 lifting the battery fixture 30 when the battery is not in place, which helps to better protect the battery during the helium inspection process.

[0045] The in-place detection component 4 includes an in-place detection component 41 and a second anti-misblocking component 42. The second anti-misblocking component 42 is used to cover the in-place detection component 41. The second anti-misblocking component 42 is provided with a second light-transmitting area 421. The second light-transmitting area 421 is arranged corresponding to the light end of the in-place detection component 41, and the second light-transmitting area 421 allows light to pass through.

[0046] The second anti-mis-blocking member 42 may be provided with a second light-transmitting hole to form a second light-transmitting area 421. The second light-transmitting hole may allow part of the light to pass through, which can effectively avoid light interference, so that the in-place detection member 41 of the two in-place detection members 41 for receiving light can accurately receive light, thereby improving the accuracy of detecting the in-place status of the battery.

[0047] The second light-transmitting hole may be arranged in any shape such as square, circle, ellipse, trapezoid, triangle or irregular shape.

[0048] The second anti-mistake blocking member 42 may also be provided with a transparent portion to form a second light-transmitting area 421. The second anti-mistake blocking member 42 is a transparent acrylic structure, and the surface of the second anti-mistake blocking member 42 is treated with an opaque coating, and the position corresponding to the optical end of the in-place detection member 21 is retained without coating treatment, so that the light-incoming area of ​​the second anti-mistake blocking member 42 can be reduced, thereby effectively avoiding light interference, so that the in-place detection member 21 can accurately receive light, and improve the detection accuracy of the battery in-place state.

[0049] It can be understood that both the in-position detection member 21 and the in-position detection member 41 are through-beam photoelectric sensors, such as through-beam laser sensors or through-beam infrared sensors.

[0050] The utility model also proposes a helium detection device, referring to Figures 1 to 3 The helium detection device includes an anti-misdetection mechanism 10, and the helium detection mechanism also includes a lifting cylinder 20 and a battery fixture 30. The lifting cylinder 20 is used to lift the battery fixture 30. The support member 1 is penetrated through the bottom plate of the battery fixture 30, and the support member 1 can guide the battery fixture 30 to move.

[0051] The specific structure of the anti-false detection mechanism 10 refers to the above embodiments. Since the helium detection device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0052] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
