As shown in fig. 1 to 3, a detection apparatus 100 provided in embodiment 1 of the present invention includes a first detection device 10, where the first detection device 10 includes a first accommodating box 11 and a first detection unit 12.

The first detecting device 10 includes a first accommodating box 11 and a plurality of first detecting units 12, the first accommodating box 11 includes a plurality of first accommodating cavities 111 and a plurality of first connecting ports 112, each of the first accommodating cavities 111 is used for accommodating the workpiece 200, and each of the first connecting ports 112 is communicated with one of the first accommodating cavities 111.

Each first detecting unit 12 is detachably connected to a first connecting port 112 of the first accommodating box 11 to detect the air tightness of the workpiece 200 in a first accommodating cavity 111.

In this embodiment, the workpiece 200 is a battery. In other embodiments, the workpiece 200 may be other products.

By the aid of the detection equipment, when specific work pieces 200 with unqualified air tightness need to be determined, a plurality of work pieces 200 are placed in the first accommodating boxes 11 at the same time, one work piece 200 is placed in each first accommodating cavity 111, and then the specific work pieces 200 with unqualified air tightness can be determined only by enabling the first detection units 12 to detect the work pieces 200 in the first accommodating cavities 111 respectively, so that detection efficiency is effectively improved.

It is understood that in embodiment 1, the number of the first detection units 12 is the same as that of the first accommodation cavities 111. In embodiment 2, the number of the first detecting units 12 may be the same as that of the first accommodating boxes 11, that is, when there is one first accommodating box 11, there is also one first detecting unit 12, and there are a plurality of connecting positions between the first detecting unit 12 and the second accommodating box 21.

When the first detecting unit 12 and the first accommodating box 11 are located at any connecting position, the first detecting unit 12 is connected to a first connecting port 112 of the first accommodating box 11 to detect the air tightness of the workpiece 200 in a first accommodating cavity 111.

When the specific work piece 200 with unqualified air tightness needs to be determined, the plurality of work pieces 200 are simultaneously placed in the first accommodating cavities 11, one work piece 200 is placed in each first accommodating cavity 111, and then the first detection unit 12 and the first accommodating cavity 11 only need to be switched between a plurality of connection positions, so that the first detection unit 12 can sequentially detect the plurality of work pieces 200, the specific work piece 200 with unqualified air tightness is determined, and the detection efficiency is effectively improved.

It should be noted that, a plurality of connection positions are provided between the first detection unit 12 and the first accommodating box 11, and the first accommodating box 11 may be fixed, and the first detection unit 12 moves, so that the first detection unit 12 is switched between the plurality of connection positions; the first detecting unit 12 may be fixed, and the first accommodating case 11 may be moved so that the first accommodating case 11 is switched between a plurality of connection positions.

Meanwhile, when the first detection unit 12 detects the air tightness of the workpiece 200, if an unqualified workpiece 200 is detected, the first detection unit 12 is polluted, the polluted first detection unit 12 cannot work continuously, and needs to be cleaned, and the workpiece can be continuously used after the cleaning is finished. When two or more workpieces 200 out of the plurality of workpieces 200 have defective airtightness, the first inspection unit 12 needs to clean one of the defective workpieces 200 before subsequent inspection.

In embodiment 1, the workpieces 200 in each first accommodating cavity 111 are detected by a corresponding first detection unit 12, and even if two or more workpieces 200 have unacceptable air tightness, all workpieces 200 with unacceptable air tightness can be detected quickly, thereby further improving the detection efficiency.

It should be explained that, generally, the probability of the airtightness failure of the workpieces 200 is low, and when the number of the workpieces 200 is two and the defective workpiece 200 is detected to exist in two workpieces 200, only one workpiece 200 is usually detected to be unqualified in airtightness detection, so the detection equipment in the embodiment 2 is adopted for detection, which can effectively reduce the detection cost.

Referring to fig. 4, in some embodiments, the detecting apparatus further includes a second detecting device 20, the second detecting device 20 includes a second accommodating chamber 21 and a second detecting unit 22, the second accommodating chamber 21 includes a second accommodating cavity 211 and a second connection port 212 communicated with the second accommodating cavity 211, the second accommodating cavity 211 is used for placing the workpiece 200, and the second detecting unit 22 is detachably connected to the second connection port 212 of the second accommodating chamber 21 to perform the air tightness detection on the workpiece 200 in the second accommodating cavity 211.

It should be noted that, during normal operation, the second detecting device 20 performs air-tightness detection on the workpieces 200, and at least two workpieces 200 can be placed in the second accommodating cavity 211, that is, the second detecting unit 22 can perform air-tightness detection on at least two workpieces 200 at the same time, so as to improve the detection efficiency.

In the embodiment shown in fig. 1, the number of the first receiving cavities 111 is two, and a separating structure is disposed in the second receiving cavity 211 to separate the second receiving cavity 211 into two portions that are communicated with each other, and each portion can receive a workpiece 200.

When the second detection unit 22 detects that there is a work 200 with an insufficient air-tightness in the at least two work 200, the at least two work 200 may be conveyed to the first accommodating box 11 for detection, so as to determine the specific work 200 with an insufficient air-tightness.

In addition, when the second detection unit 22 detects the work piece 200 with the unqualified air tightness, the second detection unit 22 is also polluted, and in order to ensure the detection efficiency, the first detection device 10 can replace the second detection device 20 to detect the subsequent work piece 200. After the second inspection unit 22 is cleaned, the first inspection device 10 continues to inspect the subsequent workpieces 200, and the second inspection device 20 can be used to inspect the workpieces 200 with the unqualified air tightness.

In practical applications, the detecting apparatus includes a plurality of second detecting devices 20, each second detecting device 20 can simultaneously detect the air tightness of at least two workpieces 200, and the detecting efficiency can be further improved by the plurality of second detecting devices 20.

As shown in fig. 1, the scrap collecting device 70 extends in the vertical direction, so that the scrap collecting device 70 can simultaneously collect a plurality of work pieces 200 with poor airtightness, thereby facilitating the subsequent centralized processing.

After the unloading device 60 takes out the workpieces 200 in the first and

11 and 21, if the workpieces 200 are airtight-acceptable, the workpieces 200 are conveyed to the next process, and if the workpieces 200 are airtight-unacceptable, the workpieces 200 are conveyed to the scrap collecting device 70 by the unloading device 60.

It should be explained that the second detecting device 20 simultaneously performs air-tightness detection on at least two workpieces 200, when detecting that there are workpieces 200 with unqualified air-tightness, the conveying device 30 can convey the second accommodating box 21 to the feeding station 101 or the blanking station 103, and then the feeding device 50 or the blanking device 60 can convey the workpieces 200 to the first accommodating box 11, and each workpiece 200 is placed in a first accommodating cavity 111 of the first accommodating box 11, and then the first detecting device 10 detects and determines the specific workpieces 200 with unqualified air-tightness.

With reference to fig. 1 and 2, the operation flow of the detection apparatus will be described by taking the first detection device 10 as an example:

initially, the first accommodating box 11 is located at the loading station 101, the loading device 50 transports the workpiece 200 into the first accommodating cavity 111, and then the conveying device 30 drives the first accommodating box 11 to move horizontally until the first accommodating box 11 moves to the detection station 102.

After the first accommodating box 11 moves to the detection station 102, the lifting device 40 drives the first accommodating box 11 to ascend until the first detection unit 12 is in butt joint with the first connection port 112 on the first accommodating box 11. Next, the first vacuum assembly 13 evacuates the first accommodating cavity 111, then the first filling assembly 14 fills the workpiece 200 with a detection substance, after the workpiece 200 is filled with the detection substance, the first accommodating cavity 111 is detected by the first detection assembly 15, if the detection substance is not detected, the airtightness of the workpiece 200 is qualified, and if the detection substance is detected, the airtightness of the workpiece 200 is not qualified.

After the first detection assembly 15 completes detection, the lifting device 40 drives the first accommodating box 11 to descend, then the conveying device 30 continues to drive the first accommodating box 11 to move until the first accommodating box 11 moves to the blanking station 103, and the blanking device 60 carries the workpieces 200 in the first accommodating box 11 to the next process or the waste collection device 70 respectively.

It should be noted that the detecting process of the second detecting device 20 is the same as the detecting process of the first detecting device 10, and the description thereof is omitted here.

In embodiment 1, as shown in fig. 1, two first receiving cavities 111 may be arranged at intervals along a direction perpendicular to a conveying direction of the conveying device 30, and two first detecting units 12 may correspond to the two first receiving cavities 111 of the first receiving boxes 11 located at the detecting station 102 one by one.

In embodiment 2, the plurality of connection positions between the first accommodating box 11 and the first detecting unit 12 are arranged at intervals along the conveying direction of the conveying device 30, that is, the plurality of first accommodating cavities 111 and the plurality of first connection ports 112 of the first accommodating box 11 are arranged at intervals along the conveying direction of the conveying device 30, and in the process that the conveying device 30 drives the first accommodating box 11 to move horizontally, the plurality of first connection ports 112 on the first accommodating box 11 may sequentially pass right below the first detecting unit 12. Therefore, the plurality of first connection ports 112 of the first accommodating box 11 can be sequentially docked with the first detection unit 12 by the conveying device 30 and the lifting device 40.

Referring to fig. 5, in some embodiments, each of the first detecting units 12 includes a first vacuum assembly 13, a first filling assembly 14, a first detecting assembly 15 and a first sealing cover 16, the first vacuum assembly 13, the first filling assembly 14 and the first detecting assembly 15 are all connected to the first sealing cover 16, and each of the first sealing covers 16 is detachably connected to a first connecting port 112 of the first accommodating box 11.

When the first sealing cover 16 is connected to the first connection port 112 of the first accommodating box 11, the first vacuum assembly 13 is communicated with the first accommodating cavity 111 for vacuumizing the first accommodating cavity 111, the first filling assembly 14 is communicated with the workpiece 200 for filling the workpiece 200 with the detection substance, and the first detection assembly 15 is communicated with the first accommodating cavity 111 for detecting the detection substance in the first accommodating cavity 111.

In this example, the detection substance was nitrogen gas.

After the first sealing cover 16 is connected to a first connection port 112, the first vacuum module 13 vacuumizes the corresponding first receiving cavity 111, the first filling module 14 fills the workpiece 200 with the detection material after vacuuming, and then the first detection module 15 detects whether the detection material exists in the first receiving cavity 111. If no detection substance is detected, the airtightness of the workpiece 200 is passed, and if a detection substance is detected, the airtightness of the workpiece 200 is failed.

In embodiment 2, when the first detecting unit 12 is located at any one of the connecting positions, the first sealing cover 16 is connected to a first connecting port 112 of the first accommodating box 11, the first vacuum assembly 13 is communicated with the first accommodating cavity 111 for vacuumizing the first accommodating cavity 111, the first filling assembly 14 is communicated with the workpiece 200 for filling the workpiece 200 with the detecting substance, and the first detecting assembly 15 is communicated with the first accommodating cavity 111 for detecting the detecting substance in the first accommodating cavity 111.

In addition, the air tightness detecting processes of embodiment 2 and embodiment 1 are the same, and the difference is only that the first sealing covers 16 in embodiment 2 need to be connected to the plurality of first connecting ports 112, respectively, while the plurality of first sealing covers 16 in embodiment 1 are connected to the plurality of first connecting ports 112, respectively, so the air tightness detecting process in embodiment 2 is not repeated.

In some embodiments, the first vacuum assembly 13 includes an exhaust pipe connected between the first sealing cover 16 and an exhaust device (vacuum generator or vacuum pump), and a vacuum control valve disposed on the exhaust pipe to control the on/off of the exhaust pipe.

It can be understood that the first sealing cover 16 is provided with a vacuum channel, when the first sealing cover 16 is connected to the first accommodating box 11, the vacuum channel is communicated with a first accommodating cavity 111, and the pumping pipeline is connected to the vacuum channel so as to be communicated with the first accommodating cavity 111.

In some embodiments, the first filling assembly 14 includes an extraction member, a filling member, a recycling member, a plurality of connecting pipes and a plurality of control valves, the extraction member, the filling member and the recycling member are all communicated with the workpiece 200 through the connecting pipes and the control valves, the extraction member first vacuums the interior of the workpiece 200, then the filling member fills the workpiece 200 with the detection substance, and after the detection of the first detection assembly 15 is completed, the recycling member extracts and recycles the detection substance in the workpiece 200.

In some embodiments, the first detecting assembly 15 includes a detecting pipe connected between the first sealing cover 16 and the detector, and a detecting control valve disposed on the detecting pipe to control the on/off of the detecting pipe.

It should be noted that, in the present embodiment, the detection substance is helium gas, and thus the detector is a helium detector. Meanwhile, it should be noted that when the first accommodating cavity 111 is evacuated, the vacuum control valve is opened and the detection control valve is closed, and when detecting whether the detection substance exists in the first accommodating cavity 111, the vacuum control valve is closed and the detection control valve is opened.

In addition, it can be understood that, the first sealing cover 16 is further provided with a detection channel, when the first sealing cover 16 is connected to the first accommodating box 11, the detection channel is communicated with a first accommodating cavity 111, and the detection pipeline is connected to the detection channel so as to be communicated with the first accommodating cavity 111.

In some embodiments, the second detecting unit 22 includes a second vacuum assembly 23, a second filling assembly 24, a second detecting assembly 25, and a second sealing cover 26, wherein the second vacuum assembly 23, the second filling assembly 24, and the second detecting assembly 25 are all connected to the second sealing cover 26, and the second sealing cover 26 is detachably connected to the second connection port 212 of the second accommodating box 21.

When the second sealing cover 26 is connected to the second sealing box, the second vacuum assembly 23 is communicated with the second accommodating cavity 211 for vacuumizing the second accommodating cavity 211, the second filling assembly 24 is communicated with the workpiece 200 for filling the workpiece 200 with the detection material, and the second detection assembly 25 is communicated with the second accommodating cavity 211 for detecting the detection material in the second accommodating cavity 211.

It should be noted that the structure of the second detecting unit 22 is the same as that of the first detecting unit 12, and the detecting process is also the same, so the description is omitted.

In addition, the vacuum pipes of the second vacuum assemblies 23 may be connected to each other, and the detection pipes of the second detection assemblies 25 may be connected to each other, so that the first receiving cavities 111 may be evacuated by one pumping device, and the second receiving cavities 211 may be detected by one detector.

Of course, the first detection units 22 may not be connected to each other to avoid affecting the use of the second detection units 22 when the workpieces 200 with poor air tightness exist.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
