[0038] 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.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. 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.

[0040] 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.

[0041] The utility model proposes a battery helium detection device, referring to Figures 1 to 5 The battery helium inspection device 100 includes a frame 1, a helium inspection module 2, a re-inspection module 3, a vacuum assembly 4, a helium injection assembly 5 and a detector 6. The frame 1 has a helium inspection station 11 and a re-inspection station 12. The frame 1 is provided with a helium inspection matching cavity 13 and a re-inspection matching cavity 14. The helium inspection matching cavity 13 is located at the helium inspection station 11, and the re-inspection matching cavity 14 is located at the re-inspection station 12.

[0042] The helium inspection module 2 is provided with a plurality of helium inspection chambers 231 for placing batteries, and the plurality of helium inspection chambers 231 are arranged in pairs, and the helium inspection module 2 is used to deliver the batteries to the helium inspection station 11, and the helium inspection chamber 231 cooperates with the helium inspection matching cavity 13 to form a closed helium inspection cavity (not shown in the figure). The re-inspection module 3 is provided with a plurality of re-inspection chambers 331 for placing batteries, and the plurality of re-inspection chambers 331 are arranged independently and separately, and the re-inspection module 3 is used to deliver the batteries to the re-inspection station 12, and the re-inspection chamber 331 cooperates with the re-inspection matching cavity 14 to form a closed re-inspection cavity (not shown in the figure).

[0043] The vacuum pumping assembly 4 and the helium injection assembly 5 can be connected to the helium inspection matching cavity 13 and the re-inspection matching cavity 14 through pipelines. The vacuum pumping assembly 4 and the helium injection assembly 5 are also connected to the detector 6, which is used to perform helium inspection on the battery in the closed helium inspection cavity or re-inspect the battery in the closed re-inspection cavity.

[0044] Based on the above-mentioned scheme, a large number of helium inspection and re-inspection of batteries can be achieved through multiple helium inspection chambers 231 separated by twos and multiple re-inspection chambers 331 independently arranged. With such a configuration, on the one hand, the helium inspection efficiency of the batteries can be guaranteed by the multiple helium inspection chambers 231, and on the other hand, the re-inspection of unqualified batteries can be achieved through the independently arranged re-inspection chambers 331. In this way, the unqualified batteries can be re-inspected independently during the re-inspection process, and the re-inspection processes are not affected by each other, thereby reducing the situation where one battery becomes unqualified again during the re-inspection, resulting in the need for all the re-inspected batteries to be re-inspected or all being classified as defective batteries. This improves the efficiency of helium inspection of batteries and the accuracy of re-inspected batteries, thereby improving the helium inspection efficiency of batteries.

[0045] The detector 6 is a helium mass spectrometer, and the detector 6 may also be other electronic devices with a helium detection function.

[0046] When the battery is subjected to helium inspection, the vacuuming component 4 and the helium injection component 5 are kept in a normally closed state together with the re-inspection module 3. The vacuuming component 4 is used to evacuate the sealed helium inspection cavity and the inside of the battery, so that the sealed helium inspection cavity is in a vacuum state. The helium injection component 5 is used to inject gas into the sealed helium inspection cavity. The injected gas is helium. The detector 6 is started, and the helium injection component 5 extracts the helium in the sealed helium inspection cavity. If the battery has a leak, the helium will leak from the inside of the battery into the sealed helium inspection cavity, and the detector 6 will identify and analyze it to determine whether the battery is leaking. If so, the battery is an unqualified battery, otherwise, the battery is a qualified battery.

[0047] The battery that failed the first helium test is grabbed by a manipulator and placed on the re-test module 3. The vacuum assembly 4 and the helium injection assembly 5 are kept in an open state with the helium test module 2, and the vacuum assembly 4 and the helium injection assembly 5 are kept in a normally closed state with the helium test module 2. The vacuum assembly 4 is used to evacuate the sealed re-test cavity and the inside of the unqualified battery, so that the sealed re-test cavity is in a vacuum state. The helium injection assembly 5 is used to inject helium into the sealed re-test cavity, the detector 6 is started, and the helium injection assembly 5 extracts helium from the sealed re-test cavity. If the battery still leaks, the detector 6 identifies and analyzes it and directly determines that the battery is an unqualified battery. Otherwise, the battery is a battery to be re-tested with helium.

[0048] Continue to refer to Figures 1 to 5 The number of helium inspection modules 2 is set in multiple groups, and multiple groups of helium inspection modules 2 are arranged side by side. In this way, a large number of helium inspection batteries can be realized in a single time, thereby better improving the helium inspection efficiency, improving the overall production efficiency, and increasing the production capacity.

[0049] The helium detection module 2 includes a driving module 21, a lifting assembly 22 and a helium detection fixture 23. The lifting assembly 22 and the helium detection fixture 23 are both connected to the driving module 21, and the driving module 21 is used to send the helium detection fixture 23 and the lifting assembly 22 to or away from the helium detection station 11. The lifting assembly 22 is arranged between the driven module 21 and the helium detection fixture 23, and the lifting assembly 22 is used to lift or lower the helium detection fixture 23. A plurality of helium detection chambers 231 are formed on the helium detection fixture 23, and the helium detection fixture 23 is also used to fix the battery.

[0050] Such a setting has a high degree of automation, and can well realize the transportation and lifting of batteries, thereby improving the efficiency of helium inspection of batteries. Multiple batteries can be placed at a time to realize batch helium inspection of batteries, thus improving the efficiency of helium inspection of batteries.

[0051] The driving module 21 may be a driving mechanism such as a cylinder, a linear motor or a screw mechanism. In the embodiment of the present application, the driving module 21 is a linear motor.

[0052] The lifting assembly 22 includes a base 221 and a lifting member 222. The base 221 is connected to the driving module 21, and the base 221 is arranged in a receiving groove 2211 for installing the lifting member 222. The helium detection module 2 also includes a lock body assembly 24, which is arranged in the receiving groove 2211. The lock body assembly 24 has a locked state and an unlocked state. In the locked state, the lock body assembly 24 locks the helium detection fixture 23; in the unlocked state, the lock body assembly 24 unlocks the helium detection fixture 23, and the lifting member 222 can drive the helium detection fixture 23 to move.

[0053] Such a configuration effectively prevents the accidental start-up of the helium inspection fixture 23 or the accident of falling due to its own gravity, improves the reliability of the helium inspection of the battery helium inspection device 100, and improves the safety factor in the production process. The lifting member 222 enables the helium inspection chamber 231 of the helium inspection fixture 23 to cooperate with the helium inspection matching cavity 13 to form a closed helium inspection cavity, so as to ensure the stability of the closed helium inspection cavity, improve the accuracy of the helium inspection of the battery, and improve the helium inspection effect.

[0054] The lifting member 222 may be a driving mechanism such as a cylinder or a linear motor. In the embodiment of the present application, the lifting member 222 may be a cylinder. It is understandable that the lifting member 222 may also be other structural members having a linear pushing function, as long as the helium inspection fixture 23 can be lifted and lowered in the vertical direction, and no specific limitation is made here.

[0055] There may be two lock body assemblies 24, both of which are used to lock or unlock the helium detection fixture 23. The two lock body assemblies 24 can improve the locking stability of the helium detection fixture 23, further reduce the situation where the helium detection fixture 23 is accidentally started, and thus improve the performance of the battery helium detection device 100.

[0056] Continue to refer to Figures 1 to 5 The lock body assembly 24 includes a power piece 241, a locking piece 242 and an elastic piece 243. The helium inspection fixture 23 is provided with a hook body 232 located in the accommodating groove 2211. One end of the locking piece 242 is rotatably connected to the base 221, and the other end is engaged with or disengaged from the hook body 232. The power piece 241 is used to drive the locking piece 242 to engage with or disengage from the hook body 232. One end of the elastic piece 243 abuts against the base 221, and the other end abuts against the locking piece 242. The elastic piece 243 is used to provide a restoring force for the locking piece 242 to reset.

[0057] With such arrangement, the overall structure is simple, stable and reliable, so as to achieve locking or releasing of the helium detection fixture 23 .

[0058] Specifically, the power member 241 may be a driving mechanism such as a micro cylinder, a micro linear motor, etc. It is understandable that the power member 241 may also be other structural members that have the function of pushing the locking member 242 to rotate, which will not be described in detail here.

[0059] The locking member 242 may be a locking rod, and one end of the locking rod close to the helium detection fixture 23 is hooked, so that it is convenient to buckle with the hook body 232 to improve the stability of locking the helium detection fixture 23, and it is also convenient to disengage and unlock. The locking member 242 may also be other structural members with a locking function, as long as it can be buckled with or disengaged from the hook body 232, and is not specifically limited here.

[0060] The elastic member 243 may be a spring, a rubber block or other structural members with elastic properties.

[0061] Continue to refer to Figures 1 to 5 The helium inspection module 2 further includes a protective member 25, which is connected to the helium inspection fixture 23 and covers the base 221, that is, the protective member 25 cooperates with the helium inspection fixture 23 to cover the notch of the receiving groove. In this way, the protective member 25 can effectively prevent the operator from inserting his hand into the receiving groove due to misoperation, thereby avoiding safety accidents, thereby improving the safety performance of the battery helium inspection device 100.

[0062] The protective member 25 may be a protective cover, a protective baffle or other structures.

[0063] Continue to refer to Figures 1 to 5The re-inspection module 3 includes a conveying module 31, a lifting assembly 32 and a re-inspection jig 33. The lifting assembly 32 and the re-inspection jig 33 are both connected to the conveying module 31, and the conveying module 31 is used to convey the re-inspection jig 33 and the lifting assembly 32 to or away from the re-inspection station 12. The lifting assembly 32 is arranged between the conveying module 31 and the re-inspection jig 33, and the lifting assembly 32 is used to lift or lower the re-inspection jig 33. A plurality of re-inspection chambers 331 are formed on the re-inspection jig 33, and the re-inspection jig 33 is also used to fix the battery.

[0064] With such arrangement, each unqualified battery can be independently re-inspected through each independently arranged re-inspection chamber 331, thus reducing the situation where one battery becomes unqualified again during re-inspection, causing the entire batch of re-inspected batteries to need to be re-inspected or all be classified as defective batteries, thereby improving the efficiency of helium inspection of batteries and the accuracy of re-inspected batteries, thereby improving the efficiency of helium inspection of batteries.

[0065] The conveying module 31 may be a driving mechanism such as a cylinder, a linear motor or a screw mechanism. In the embodiment of the present application, the conveying module 31 is a linear motor.

[0066] The lifting assembly 32 can be a cylinder or a linear motor. The re-inspection fixture 33 has the same structure as the helium inspection fixture 23, and the re-inspection fixture 33 also has a locking function. The specific structure of the re-inspection fixture 33 can refer to the helium inspection fixture 23, and will not be described in detail here.

[0067] Continue to refer to Figures 1 to 5 The vacuum pumping assembly 4 includes a driving pump, a vacuum pipe, a helium detection control valve and a re-inspection control valve. The vacuum pipe is connected to the helium detection matching chamber 13 and the re-inspection matching chamber 14. The helium detection control valve is used to open or close the connection between the vacuum pipe and the helium detection matching chamber 13, and the re-inspection control valve is used to open or close the connection between the vacuum pipe and the re-inspection matching chamber 14. The driving pump is used to evacuate the closed helium detection cavity or the closed re-inspection cavity through the vacuum pipe.

[0068] The helium injection assembly 5 includes a power pump, a gas injection pipeline, a helium inspection gas injection control valve, and a re-inspection gas injection control valve. The gas injection pipeline is connected to the helium inspection matching cavity 13 and the re-inspection matching cavity 14, the helium inspection gas injection control valve is used to open or close the connection between the gas injection pipeline and the helium inspection matching cavity 13, and the re-inspection gas injection control valve is used to open or close the connection between the gas injection pipeline and the re-inspection matching cavity 14. The power pump is used to inject gas into the closed helium inspection cavity or the closed re-inspection cavity through the gas injection pipeline.

[0069] Wherein, both the driving pump and the power pump can be pump body structures.

[0070] 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.
