Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] Features in the terms "first", "second" and the like in the description and claims of this application may explicitly or implicitly include one or more of the features.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it 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. 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] Please refer to Figures 1 to 4 The embodiment of the present application discloses an airtight detection device, which includes a base frame 100, a first conveying part 200, a second conveying part 300, a first driving mechanism 400 and a detection mechanism 500.

[0027] The base frame 100 is a basic component of the airtight detection device, and is used to provide installation positions for other components of the airtight detection device, wherein the first transport portion 200, the second transport portion 300 and the detection mechanism 500 are all arranged on the base frame 100. In addition, the base frame 100 is also used to form some functional spaces or structures.

[0028] The first conveying part 200 and the second conveying part 300 are core components for conveying products in the airtight detection device. The first conveying part 200 and the second conveying part 300 are both movably provided on the base frame 100, so that the products loaded on the first conveying part 200 and the second conveying part 300 can be conveyed by moving relative to the base frame 100.

[0029] The first driving mechanism 400 is the core structure of the airtight detection device for driving the first transport part 200 and the second transport part 300 to move. The first transport part 200 and the second transport part 300 are both connected to the first driving mechanism 400, so that the first driving mechanism 400 can drive the first transport part 200 and the second transport part 300 to move, and realize the movement of the first transport part 200 and the second transport part 300 relative to the base frame 100. Specifically, the first driving mechanism 400 can be provided on the base frame 100, so as to facilitate the modular design of the airtight detection device.

[0030] The detection mechanism 500 is the core structure of the airtight detection device for realizing the detection of the product. The detection mechanism 500 is connected to the base frame 100 and is used to cooperate with the first conveying part 200 or the first conveying part 200 to realize the detection of the product.

[0031] In a specific working process, the airtight detection device can switch between a first state and a second state. In the first state, the first driving mechanism 400 drives the first conveying part 200 to move to a detection position opposite to the detection mechanism 500 for cooperating with the detection mechanism 500, thereby enabling detection of the product on the first conveying part 200. At the same time, the first driving mechanism 400 drives the second conveying part 300 to move to a transfer position that is offset from the detection mechanism 500, so that when the first conveying part 200 cooperates with the detection mechanism 500 to detect the product, the second conveying part 300 can continue to load the product and wait for the detection mechanism 500 to detect it, so that the product can be transported to the detection position opposite to the detection mechanism 500 for detection in a timely manner, which is beneficial to shorten the waiting time of the detection mechanism 500, and further can improve the detection efficiency of the airtight detection device.

[0032] In the second state, the first driving mechanism 400 drives the second conveying part 300 to move to a detection position opposite to the detection mechanism 500 for cooperating with the detection mechanism 500, thereby realizing detection of the product on the second conveying part 300. At the same time, the first driving mechanism 400 drives the first conveying part 200 to move to a transfer position that is offset from the detection mechanism 500, so that when the second conveying part 300 cooperates with the detection mechanism 500 to detect the product, the first conveying part 200 can continue to load the product and wait for the detection mechanism 500 to detect it, so that the product can be transported to the detection position opposite to the detection mechanism 500 for detection in time, which is beneficial to shorten the waiting time of the detection mechanism 500, and further can improve the detection efficiency of the airtight detection device.

[0033] The airtight detection device disclosed in the embodiment of the present application improves the structure of the airtight detection device involved in the related art, and by setting the first conveying part 200 and the second conveying part 300, by setting in the first state, the first driving mechanism 400 can drive the first conveying part 200 to move to the detection position relative to the detection mechanism 500, so that the first conveying part 200 can cooperate with the detection mechanism 500, and drive the second conveying part 300 to move to the transfer position displaced from the detection mechanism 500, so as to continue to load the product, and by setting in the second state, the first driving mechanism 400 can drive the first conveying part 200 to move to the transfer position displaced from the detection mechanism 500, so as to continue to load the product, and drive the second conveying part 300 to move to the detection position relative to the detection mechanism 500, so that the second conveying part 300 can cooperate with the detection mechanism 500.

[0034] This structure allows one of the first conveying part 200 and the second conveying part 300 to cooperate with the detection mechanism 500 to detect the product, while the other can continue to load the product and wait for the detection mechanism 500 to detect it, so that the product can be transported to the detection position opposite to the detection mechanism 500 in time for detection, which is beneficial to shorten the waiting time of the detection mechanism 500, and further can improve the detection efficiency of the airtight detection device.

[0035] Specifically, if the airtight detection device only includes the first transport part 200, then after the first transport part 200 at the detection position cooperates with the detection mechanism 500 to complete the detection of the product, the first transport part 200 needs to move from the detection position to the transfer position to remove the detected product and reload the uninspected product, and then move to the detection position to continue to cooperate with the detection mechanism 500 to realize the detection of the product, which requires the detection mechanism 500 to wait for a long time.

[0036] In the airtight detection device disclosed in the present application, when one of the first conveying part 200 and the second conveying part 300 that is in the detection position cooperates with the detection mechanism 500 to detect the product, the other one that is in the transfer position can continue to load the product and wait for the detection mechanism 500 to detect it, so that the one of the first conveying part 200 and the second conveying part 300 that is in the transfer position can move from the transfer position to the detection position in time after the detection mechanism 500 completes the detection, so as to shorten the waiting time of the detection mechanism 500, so that the detection mechanism 500 can continue the detection after waiting for a shorter time.

[0037] In a further technical solution, the first driving mechanism 400 may include a first transmission part 410 and a second transmission part 420, both of which may be arranged on the base frame 100, and the first transport part 200 may be connected to the first transmission part 410, so that the first transmission part 410 can drive the first transport part 200 to move, and both of the first transport part 200 and the second transport part 300 may be connected to the second transmission part 420, so that the first transport part 200 can drive the second transport part 300 to move through the second transmission part 420. This structure can realize the movement of the first transport part 200 and the second transport part 300 by setting a power source to drive the first transmission part 410, avoiding the need to set multiple power sources to drive the first transport part 200 and the second transport part 300 respectively, so that the first transport part 200 and the second transport part 300 can better move synchronously, and is conducive to cost saving.

[0038] In the specific working process, in the first state, the first transmission part 410 can drive the first transport part 200 to move to the detection position, so as to cooperate with the detection mechanism 500, so as to realize the detection of the product on the first transport part 200. Since the first transport part 200 and the second transport part 300 are both connected to the second transmission part 420, the first transport part 200 can drive the second transmission part 420 to move, and the second transmission part 420 can drive the second transport part 300 to move, so that the first transport part 200 can drive the second transport part 300 to move to the transfer position through the second transmission part 420, so that when the first transport part 200 cooperates with the detection mechanism 500 to detect the product, the second transport part 300 can continue to load the product and wait for the detection mechanism 500 to detect it.

[0039] In the second state, the first transmission part 410 can drive the first conveying part 200 to move to the transfer position to continue loading products and wait for the detection mechanism 500 to detect. At the same time, the conveying part 200 can drive the second transmission part 420 to move, so that the second transmission part 420 can drive the second conveying part 300 to move, so that the first conveying part 200 can drive the second conveying part 300 to move to the detection position through the second transmission part 420, so as to cooperate with the detection mechanism 500 to realize the detection of the product on the second conveying part 300.

[0040] Of course, in other embodiments, the first transport part 200 can be connected to the first transmission part 410, and the second transport part 300 can be connected to the second transmission part 420, so as to drive the first transport part 200 and the second transport part 300 to move respectively through the first transmission part 410 and the second transmission part 420, so that two power sources can be set to drive the first transmission part 410 and the second transmission part 420 respectively, which is conducive to balancing the load of each power source.

[0041] In a feasible technical solution, the first transmission part 410 may include a first guide rail 411 and a first slider 412. The first guide rail 411 may be fixed to the base frame 100. The first slider 412 may be slidably guided and matched with the first guide rail 411 along the extension direction of the first guide rail 411, and may be fixedly connected to the first transport part 200 to drive the first transport part 200 to move along the extension direction of the first guide rail 411. This structure enables the first transport part 200 to move smoothly and stably along the extension direction of the first guide rail 411 through the cooperation between the first slider 412 and the first guide rail 411, so that the airtight detection device can operate stably. It should be noted that the distribution direction of the transmission position and the detection position may be parallel to the extension direction of the first guide rail 411.

[0042] In addition, the first guide rail 411 can be a lead screw, and accordingly, the first slider 412 can be a lead screw nut. The first guide rail 411 can also be a cylinder, and accordingly, the first slider 412 can also be a piston. The embodiment of the present application does not limit the specific structure of the first guide rail 411 and the first slider 412.

[0043] In an optional technical solution, the second transmission part 420 may include a transmission belt 421, a first transmission wheel 422 and a second transmission wheel 423. The first transmission wheel 422 and the second transmission wheel 423 may be arranged on the base frame 100 at intervals and opposite to each other. The transmission belt 421 may be sleeved outside the first transmission wheel 422 and the second transmission wheel 423, and may be in rolling contact with the first transmission wheel 422 and the second transmission wheel 423 respectively, so that the first transmission wheel 422 and the second transmission wheel 423 can be driven to roll by the transmission belt 421, or the first transmission wheel 422 and the second transmission wheel 423 can be driven to roll by the transmission belt 421.

[0044] The first transport part 200 and the second transport part 300 can be fixedly connected to opposite sides of the transmission belt 421, so that the transmission belt 421 drives the second transport part 300 to move in the direction opposite to the movement direction of the first transport part 200, so that when the first transport part 200 moves from the detection position to the transmission position (or from the transmission position to the detection position), the transmission belt 421 can drive the second transport part 300 to move from the transmission position to the detection position (or from the detection position to the transmission position), so that the first transport part 200 and the second transport part 300 can move to the detection position alternately. This structure is relatively simple and is conducive to cost saving. The transmission belt 421 has good flexibility and elasticity, can absorb impact and vibration loads, make the movement of the second transport part 300 more stable, and can reduce noise.

[0045] Specifically, the first transport part 200 may include a first clamping member, and the second transport part 300 may include a second clamping member 380. The first clamping member and the second clamping member 380 may be clamped and fixed to opposite sides of the transmission belt 421, respectively, so that the first transport part 200 and the second transport part 300 may be fixedly connected to opposite sides of the transmission belt 421, respectively. This structure can avoid damaging the transmission belt 421, and when the transmission belt 421 is worn, the first clamping member and the second clamping member 380 can be loosened to replace the transmission belt 421, thereby facilitating maintenance. Of course, the first transport part 200 and the second transport part 300 may also be connected to the transmission belt 421 by bonding, respectively. The embodiment of the present application does not limit the specific connection method between the first transport part 200 and the transmission belt 421 and between the second transport part 300 and the transmission belt 421.

[0046] In a further technical solution, both the first transmission wheel 422 and the second transmission wheel 423 can be multiple, and the multiple first transmission wheels 422 are respectively opposite to the multiple second transmission wheels 423, and the multiple first transmission wheels 422 and the multiple second transmission wheels 423 are arranged on the base frame 100 at intervals to avoid interference between the multiple first transmission wheels 422 and the multiple second transmission wheels 423, thereby affecting the normal operation of the second transmission part 420. In this structure, the multiple first transmission wheels 422 and the multiple second transmission wheels 423 can optimize power distribution, making the power distribution more uniform, thereby helping to reduce energy loss.

[0047] In other embodiments, the second transmission part 420 may include a transmission chain, a first transmission wheel 422 and a second transmission wheel 423, the first transmission wheel 422 and the second transmission wheel 423 may be arranged at intervals and opposite to each other on the base frame 100, the transmission chain may be sleeved outside the first transmission wheel 422 and the second transmission wheel 423, and may be respectively engaged with the first transmission wheel 422 and the second transmission wheel 423, and the first transport part 200 and the second transport part 300 may be respectively fixedly connected to opposite sides of the transmission chain, so that the transmission chain drives the second transport part 300 to move in a direction opposite to the movement direction of the first transport part 200. This structure can avoid elastic sliding and slipping in the transmission, so as to more accurately drive the second transport part 300 to move.

[0048] In one embodiment, the base frame 100 can be provided with a guide groove 110, and the second transport part 300 can be slidably connected to the guide groove 110, and can be guided and cooperated with the guide groove 110 along the extension direction of the guide groove 110. The guide groove 110 may include a first guide section 111, a second guide section 112 and a third guide section 113 that are interconnected. The second guide section 112 can be arranged between the first guide section 111 and the third guide section 113, and can be recessed in a direction away from the first transport part 200, so that the second transport part 300 can be guided to rise and fall through the cooperation between the second transport part 300 and the guide groove 110, so as to guide the second transport part 300 to avoid the first transport part 200 during the switching process between the first state and the second state.

[0049] Specifically, since the second guide section 112 is disposed between the first guide section 111 and the third guide section 113, during the switching process between the first state and the second state, the first transport unit 200 moves from the detection position to the transfer position (or from the transfer position to the detection position), and the second transport unit 300 moves from the transfer position to the detection position (or from the detection position to the transfer position), which causes the first transport unit 200 and the second transport unit 300 to move closer to each other and then away from each other, and the second guide section 112 is recessed in the direction away from the first transport unit 200, which can guide the second transport unit 300 to descend, thereby avoiding interference between the first transport unit 200 and the second transport unit 300. This structure is relatively simple, and can improve the stability of the movement of the second transport unit 300 while guiding the second transport unit 300 to avoid the first transport unit 200, and try to avoid the second transport unit 300 from deflecting during the movement.

[0050] In the embodiment of the present application, the second transport part 300 may include a transmission fitting 310, a second transport body 320 and a connecting part 330. The transmission fitting 310 and the second transport body 320 may be spaced and arranged opposite to each other. The first end of the connecting part 330 may be connected to the second transport body 320. The transmission fitting 310 may be provided with an avoidance hole 311. The second end of the connecting part 330 may pass through the avoidance hole 311 and be slidably connected to the guide groove 110 so that the second transport body 320 is guided and matched with the guide groove 110 through the connecting part 330, so that the second transport body 320 can be lifted and lowered through the cooperation between the connecting part 330 and the guide groove 110 to avoid the first transport part 200.

[0051] The transmission fitting 310 can be connected to the transmission belt 421, so that the transmission fitting 310 can be driven to move through the transmission belt 421, and the connecting part 330 is penetrated by the transmission fitting 310 through the avoidance hole 311, and the connecting part 330 is connected to the second carrying body 320, so that the transmission fitting 310 can drive the second carrying body 320 to move through the connecting part 330.

[0052] That is, the connecting portion 330 and the second transport body 320 can move with the transmission fitting 310, and the second transport body 320 can be raised and lowered by the cooperation of the connecting portion 330 and the guide groove 110 to avoid the first transport portion 200. In this structure, since the connecting portion 330 is inserted into the transmission fitting 310 through the avoidance hole 311, when the connecting portion 330 and the guide groove 110 cooperate to raise and lower the second transport body 320, the connecting portion 330 can avoid raising and lowering the transmission fitting 310 through the avoidance hole 311, thereby avoiding pulling the transmission belt 421 connected to the transmission fitting 310 to avoid affecting the normal operation of the transmission belt 421.

[0053] In order to improve the stability of the lifting and lowering of the second transport body 320, the second transport part 300 may further include a guide column 340, the second transport body 320 may be provided with a guide hole 321, the first end of the guide column 340 may be fixedly connected to the transmission fitting 310, the second end of the guide column 340 may be inserted into the guide hole 321, and the second transport body 320 may be slidably guided and matched with the guide column 340 along the distribution direction of the transmission fitting 310 and the second transport body 320 through the guide hole 321, wherein the distribution direction of the transmission fitting 310 and the second transport body 320 may be parallel to the lifting and lowering direction of the second transport body 320.

[0054] This structure can guide the second transport body 320 to rise and fall through the sliding fit between the guide hole 321 and the guide column 340, so that the second transport body 320 can rise and fall more stably. At the same time, since the guide column 340 is fixedly connected to the transmission fitting 310, the transmission fitting 310 can drive the second transport body 320 to move through the guide column 340. This structure does not require the transmission fitting 310 to drive the connection part 330 to move through the avoidance hole 311, that is, the movement of the second transport body 320 can be achieved, thereby avoiding the problem that the connection part 330 easily hits the avoidance hole 311 during the movement and causes the connection part 330 to malfunction, thereby avoiding affecting the normal rise and fall of the connection part 330, so as to avoid affecting the normal rise and fall of the second transport body 320.

[0055] In order to further improve the stability of the lifting and lowering of the second carrying body 320, there can be multiple guide columns 340 and guide holes 321, and the multiple guide columns 340 can respectively cooperate with the multiple guide holes 321, so that the second carrying body 320 can be lifted and lowered more stably, and when the transmission matching part 310 drives the second carrying body 320 to move, the load can be dispersed on the multiple guide columns 340, which is beneficial to reduce the load of each guide column 340, thereby avoiding excessive load on the guide column 340 and easy damage.

[0056] In an embodiment of the present application, the airtight detection device may further include a second buffer portion 620, which may be fixed to the base frame 100. In the second state, the second transport portion 300 is located at the detection position, and the first transport portion 200 is located at the transmission position. The second buffer portion 620 may elastically abut against the side of the transmission fitting 310 that is away from the first transport portion 200 to buffer the transmission fitting 310, and the guide column 340 connected to the transmission fitting 310 is inserted into the guide hole 321 of the second transport portion 300, so that the second buffer portion 620 can indirectly buffer the second transport body 320 through the transmission fitting 310, so as to buffer when the second transport portion 300 moves to the detection position.

[0057] In this structure, when the second buffer portion 620 buffers the second transport portion 300, the second buffer portion 620 elastically abuts against the transmission fitting 310, so that the transmission fitting 310 is impacted by the second buffer portion 620, and the transmission fitting 310 can share the impact force through the guide column 340, thereby avoiding the connection portion 330 from being subjected to the impact force, avoiding damage to the connection portion 330 that may easily affect its sliding in the guide groove 110, and further avoiding affecting the lifting and lowering of the second transport body 320.

[0058] In order to buffer the first transport part 200, the airtight detection device may further include a first buffer part 610. The first buffer part 610 may be fixed to the base frame 100. In the first state, the first transport part 200 is located at the detection position, and the second transport part 300 is located at the transfer position. The first buffer part 610 may elastically abut against the side of the first transport part 200 facing away from the second transport part 300 to provide buffering when the first transport part 200 moves to the detection position.

[0059] In order to improve the stability of the movement of the transmission fitting 310, the base frame 100 may further include a second guide rail 120, and the second transport part 300 may further include a second slider 370. The second slider 370 may be fixed to the side of the transmission fitting 310 away from the second transport body 320, and the second slider 370 may be slidably guided and matched with the second guide rail 120 along the extension direction of the second guide rail 120, so that after the transmission fitting 310 is driven by the transmission belt 421, it can be stably moved along the second guide rail 120 through the second slider 370. It should be noted that the distribution direction of the transmission position and the detection position may be parallel to the extension direction of the second guide rail 120.

[0060] Of course, there can be multiple second guide rails 120 and multiple second sliders 370, and the multiple second sliders 370 can be respectively slidably guided and matched with the multiple second guide rails 120, so that the transmission matching member 310 can move more stably along the multiple second guide rails 120 through the multiple second sliders 370.

[0061] In order to improve the stability of the movement of the first transport part 200, the base frame 100 may further include a third guide rail 130, and the first transport part 200 may further include a third slider 220.

It should be noted that the distribution direction of the transmission position and the detection position may be parallel to the extension direction of the third guide rail 130.

[0062] Of course, in order to further improve the stability of the movement of the first transport part 200, there can be multiple third guide rails 130 and multiple third sliders 220, and the multiple third sliders 220 can be respectively slidably guided and cooperated with the multiple third guide rails 130, so that the first transport part 200 can move more stably along the multiple third guide rails 130 through the multiple third sliders 220.

[0063] In an optional technical solution, the second transporting part 300 may further include a rolling body 350, the second end of the connecting part 330 may be rotatably connected to the rolling body 350, and the rolling body 350 may be disposed in the guide groove 110 and may be rollingly matched with the guide groove 110. In this structure, there is rolling friction between the rolling body 350 and the guide groove 110, which is conducive to reducing the wear of the rolling body 350, thereby extending the service life of the rolling body 350, and further conducive to improving the reliability of the second transporting part 300.

[0064] In the embodiment of the present application, the airtight detection device may further include a second driving mechanism 700, which may be fixed to the base frame 100 and connected to the detection mechanism 500. The second driving mechanism 700 may be used to drive the detection mechanism 500 to move toward or away from the detection position, so that the detection mechanism 500 can be lowered or raised, so that the detection mechanism 500 can cooperate with the first transport part 200 or the second transport part 300. Specifically, the second driving mechanism 700 may be a cylinder, a hydraulic cylinder or a rack and pinion mechanism, which is not limited in the embodiment of the present application.

[0065] In the specific working process, in the first state, the first conveying part 200 is located at the detection position, the second conveying part 300 is located at the transfer position, and the second driving mechanism 700 can drive the detection mechanism 500 to move in a direction close to the detection position, so that the detection mechanism 500 can cooperate with the first conveying part 200 to perform detection. After the detection is completed, the second driving mechanism 700 can drive the detection mechanism 500 to move in a direction away from the detection position, so that the first conveying part 200 can leave the detection position and move toward the transfer position.

[0066] In the second state, the second conveying part 300 is located at the detection position, the first conveying part 200 is located at the detection and transfer position, and the second driving mechanism 700 can drive the detection mechanism 500 to move in a direction close to the detection position, so that the detection mechanism 500 can cooperate with the second conveying part 300 to perform detection. After the detection is completed, the second driving mechanism 700 can drive the detection mechanism 500 to move in a direction away from the detection position, so that the second conveying part 300 can leave the detection position and move toward the transfer position.

[0067] This structure can drive the detection mechanism 500 to move toward or away from the detection position through the second driving mechanism 700, so that when performing detection, the detection mechanism 500 can be driven by the second driving mechanism 700 to be close to the first conveying part 200 or the second conveying part 300 to avoid hindering the first conveying part 200 or the second conveying part 300 from moving to the detection position. At the same time, after the detection is completed, the detection mechanism 500 can be driven by the second driving mechanism 700 to be away from the first conveying part 200 or the second conveying part 300 to avoid hindering the first conveying part 200 or the second conveying part 300 from leaving the detection position, which is beneficial to improving the reliability of the airtight detection device.

[0068] In a further technical solution, the airtight detection device may further include a position limiting support portion 800, which may be fixed to the base frame 100 and may be opposite to the detection mechanism 500. In the first state, the side of the first transporting portion 200 away from the detection mechanism 500 is supported by the position limiting support portion 800, so as to limit the movement of the detection mechanism 500 in the direction close to the first transporting portion 200 through the first transporting portion 200. Specifically, when the second driving mechanism 700 drives the detection mechanism 500 to move in the direction close to the detection position to contact the first transporting portion 200 located at the detection position, the position limiting support portion 800 can indirectly support the detection mechanism 500 by supporting the first transporting portion 200, thereby limiting the movement of the detection mechanism 500 in the direction close to the first transporting portion 200, so as to indirectly achieve the position limiting of the detection mechanism 500 by supporting the first transporting portion 200.

[0069] In the second state, the side of the second conveying part 300 facing away from the detection mechanism 500 is supported by the position limiting support part 800, so as to limit the detection mechanism 500 from moving in the direction close to the second conveying part 300 through the second conveying part 300. Specifically, when the second driving mechanism 700 drives the detection mechanism 500 to move in the direction close to the detection position to contact the second conveying part 300 located at the detection position, the position limiting support part 800 can indirectly support the detection mechanism 500 by supporting the second conveying part 300, thereby limiting the detection mechanism 500 from moving in the direction close to the second conveying part 300, so as to indirectly limit the detection mechanism 500 by supporting the second conveying part 300.

[0070] This structure can prevent the detection mechanism 500 from colliding with the first conveying part 200 or the second conveying part 300 located at the detection position during its movement toward the detection position, thereby causing damage to the first conveying part 200 or the second conveying part 300. At the same time, this structure can prevent the limit support part 800 from directly contacting the detection mechanism 500, which can easily affect the stroke of the detection mechanism 500 and cause the third jig 510 of the detection mechanism 500 described later to be difficult to seal with the first jig 210 of the first conveying part 200 described later or the second jig 360 of the second conveying part 300 described later.

[0071] In an optional technical solution, the first conveying part 200 may further include a first jig 210 , the second conveying part 300 may further include a second jig 360 , and the inspection mechanism 500 may include a third jig 510 , wherein both the first jig 210 and the second jig 360 may be used to load products.

[0072] In the specific working process, in the first state, the second driving mechanism 700 can be used to drive the detection mechanism 500 to move toward the detection position, that is, the second driving mechanism 700 can be used to drive the detection mechanism 500 to descend, so that the third jig 510 and the first jig 210 are sealed and matched, so that the third jig 510 and the first jig 210 can form a first accommodating space for accommodating products, thereby enabling the products in the first accommodating space to be detected.

[0073] In the second state, the second driving mechanism 700 can be used to drive the detection mechanism 500 to move toward the detection position, that is, the second driving mechanism 700 can be used to drive the detection mechanism 500 to descend, so that the third jig 510 and the second jig 360 can be sealed and matched, so that the third jig 510 and the second jig 360 can enclose a second accommodating space for accommodating products, so that the products in the second accommodating space can be detected. This structure is relatively simple and convenient for production and manufacturing.

[0074] Optionally, the detection mechanism 500 may further include a detection tube 520, which may be disposed on the third metallurgical tool 510. In a specific working process, in a first state, the first storage space is connected to the external environment through the detection tube 520, so that the first storage space can be blown or inhaled through the detection tube 520 to detect the air tightness of the product in the first storage space. In a second state, the second storage space is connected to the external environment through the detection tube 520, so that the second storage space can be blown or inhaled through the detection tube 520 to detect the air tightness of the product in the second storage space.

[0075] In the embodiment of the present application, the products detected by the airtight detection device are not limited to batteries. The airtight detection device can also perform airtight detection on other products, such as sealed packaged food. The embodiment of the present application does not limit the specific types of products.
