Background
The foregoing lithium battery mainly refers to, but is not absolutely limited to, a lithium battery used in an electric vehicle (also referred to as a "new energy vehicle"). As is known in the art, a lithium battery includes a case, a lithium battery core (formed by a plurality of positive and negative plates insulated and separated by a diaphragm) disposed in a cavity of the case, and a cover plate, i.e., a lithium battery cover plate. The lithium battery has the advantages of large capacity, light weight, long service period, high energy density, no memory effect, low self-discharge rate, environmental friendliness and the like, so the lithium battery is well accepted in the industry and widely applied to electric automobiles, electric bicycles, various hardware tools and the like.
The foregoing lithium battery cover plate is an important part of the structural system of the lithium battery and is not disclosed in the published chinese patent documents, such as CN203721782U (power lithium battery cover plate), CN203871392U (integrated high riveting type lithium battery cover plate), CN104466043A (a post type lithium battery cover plate and a post type lithium battery using the same), CN105810857A (a lithium battery upper cover assembly), CN202308090U (post type lithium battery cover plate), and CN102339959A (post type lithium battery cover plate), etc.
In order to ensure the quality and safety of the lithium battery during use, the shell cover plate and the lithium battery cell are generally required to be tested. Taking the lithium battery cover plate as an example, the requirements on the air tightness and the anti-creeping performance of the insulation part are very strict, because if the air tightness is poor, the reliability of the new energy electric automobile can be directly influenced, and because if the insulation performance of the electric insulation part is insufficient, safety accidents can be caused.

From the conventional point of view, after the leakage detection project of the lithium battery cover plate is completed, qualified lithium battery cover plates without insulation problems can be taken away from the leakage detection station by online detection personnel, but if the lithium battery cover plate leakage detection mechanism is arranged by taking the lithium battery cover plate leakage detection qualified product output mechanism as a carrier in order to embody the compact structure effect of the whole testing device, namely the lithium battery cover plate leakage detection mechanism is reasonably carried on the lithium battery cover plate leakage detection qualified product output mechanism with the automatic output function, not only can the workers for taking away the lithium battery cover plates after the leakage test be removed (namely, the workers are not used), but also precious labor resources can be saved, and the occupied area of the lithium battery cover plate testing device can be reduced, and good modularization and dynamic testing can be embodied to a great extent due to the fact that the lithium battery cover plate leakage detection mechanism is carried on the lithium battery cover plate leakage detection qualified product output mechanism The consistency effect of the output action is achieved.

Before the aforementioned four lithium battery cover plates 50 on the lithium battery cover plate inspection input mechanism 2 are moved to the lithium battery cover plate air tightness alternative detection mechanism 3 by the aforementioned lithium battery cover plate moving manipulator 9, the lithium battery cover plate air tightness alternative detection mechanism 3 has two of the same structures so as to embody the alternative detection and achieve the purpose of improving the detection efficiency. Now, taking the state shown in fig. 7 as an example, the applicant takes the state that the left lithium battery cover plate airtightness alternating detection mechanism 3 is in the airtightness detection process, and the right lithium battery cover plate airtightness alternating detection mechanism 3 side is in the state of receiving four lithium battery cover plates 50 extracted from the group of lithium battery cover plate separation devices 28 of the lithium battery cover plate delivery input mechanism 2 by the lithium battery cover plate transportation manipulator 9. In order to realize this state, the electrical controller 30 operates the air-tightness detection bearing frame forward and backward displacement driving cylinder 313, so that the air-tightness detection bearing frame forward and backward displacement driving cylinder slider 3132 drives the lower suction template 321 and the upper lithium battery cover plate 322 to be tested to move forward to a state shown in fig. 7, when the front end surface of the lower suction template 321 contacts the signal collector 3142 at the front position of the lower suction template, the signal collector 3142 at the front position of the lower suction template feeds back a signal to the electrical controller 30, so that the air-tightness detection bearing frame forward and backward displacement driving cylinder 313 stops operating, and four lithium battery cover plates 50 are simultaneously introduced into the four lithium battery cover plate detection accommodating cavities 3222 by the lithium battery cover plate transferring manipulator 9, the structure of which will be described in detail below. It should be noted that: the left and right displacement of the lithium battery cover plate transfer manipulator 9 between each station is driven by a left and right displacement driving mechanism 8 of the lithium battery cover plate transfer manipulator controlled by a PLC (programmable logic controller) of the electric controller 30.
After the four lithium battery cover plate detection accommodating cavities 3222 of the lithium battery cover plate upper template 322 to be tested are respectively connected with the lithium battery cover plates 50, signals (mentioned below) are fed back to the electric controller 30 due to the upward movement of the lithium battery cover plate transfer manipulator 9, the electric controller 30 sends out an instruction to enable the air tightness detection bearing frame forward and backward displacement driving acting cylinders 313 to reversely act relative to the above, so that the lithium battery cover plate air tightness detection bearing frame 32 is rearwardly displaced below the air-extracting upper template 34, the degree of rearward displacement of the lithium battery cover plate air tightness detection bearing frame 32 is based on the condition that the rear end surface of the air-extracting lower template 321 contacts the air-extracting lower template rear position signal collector 3152, when the air tightness detection bearing frame air-extracting upper template air-extracting air, the upper template pressing plate 361 is pushed to move downwards by the upper template lifting cylinder column 3631, the upper template pressing plate 361 pushes the upper template frame 35 and the air-extracting upper template 34 to move downwards, so that the air-extracting upper template 34 and the upper template 322 of the lithium battery cover plate to be tested, which plays a lower die effect, are folded, that is, four lithium battery cover plates 50 are respectively limited in the four lithium battery cover plate detection accommodating cavities 3222.
Under the above state, due to the matching of the extracted air upper template 34 and the upper template 322 of the lithium battery cover plate to be tested, the template matching signal collector 349 and the template matching signal collector 3226 generate a signal, so that the signal is fed back to the electric controller 30 by the template matching signal collector 3226, the electric controller 30 sends an instruction to the vacuum pumping mechanism 10, the vacuum pumping mechanism 10 starts to perform vacuum pumping, meanwhile, the air guide block 334 is driven to move backwards by the backward movement of the extracted air lower template 321, the air guide block vent hole 3341 on the air guide block 334 is in butt joint with the air valve 333, the air valve 333 is in an open state, and when air in the air storage tank (the air storage tank in the invention is introduced from the detection air inlet pipe coupling hole 3322 through a pipeline, the air in turn passes through the air guide block air guide corresponding hole 3341 and the detection air transition inlet pipe 336, A detection gas outlet hole 3351 of the detection gas distribution seat 335, a lithium battery cover plate detection accommodation cavity airway 337, a lithium battery cover plate detection accommodation cavity airway connection hole 3223, an accommodation cavity airway 3224 and an accommodation cavity outlet hole 3225, if the lithium battery cover plate 50 still located in the lithium battery cover plate detection accommodation cavity 3222 has poor sealing performance, i.e. has an air leakage situation, then under the operation of the vacuum pumping mechanism 10 connected with the upper air pumping template air pumping connector 341 through a pipeline, the aforementioned gas (helium) is led out from the accommodation cavity outlet hole 3225 through the lithium battery cover plate 50, the upper air pumping template air cavity 343 on the upper air pumping template 34, the upper air pumping template small air cavity communication airway 344, the upper air pumping template airway 342 and the upper air pumping connector of the upper air pumping template in sequence through pipelines, the pressure value of the vacuum pumping mechanism 10 is reduced to below the set value required by the process, so that the vacuum pumping mechanism 10 feeds back signals to the electric controller 30, and as long as any one of the four lithium battery lids 50 has a sealing problem, the four lithium battery lids are not allowed to flow into the following steps. On the contrary, when there is not the leakproofness problem in four lithium battery cover plates 50, in order to fully ensure the quality, vacuum pumping detection is carried out again by the aforementioned vacuum pump 40, specifically: under the operation of the vacuum pump 40, the gas in the pipeline connected to the vacuum pumping mechanism 10 is pumped and supplied to the mass spectrometer 20, and if the mass spectrometer 20 detects that helium gas is present in the gas, a signal is fed back to the electric controller 30 by the mass spectrometer 20. After the detection is completed, according to the reverse operation process, the upper template frame pressing device 36 moves the upper air-extracting template 34 upwards, and then the lithium battery cover plate air-tightness detection bearing frame 32 moves forwards to the state shown in fig. 7. If the lithium battery cover plate 50 has the sealing problem, the lithium battery cover plate is moved to the lithium battery cover plate air tightness unqualified detection product output mechanism 4 by the lithium battery cover plate moving manipulator 9, the lithium battery cover plate air tightness unqualified detection product output mechanism 4 outputs the lithium battery cover plate air tightness unqualified detection product, and after collection, the secondary or multiple times of screening detection of the sealing performance in a picking mode is carried out until the finally confirmed lithium battery cover plate 50 with the sealing problem is detected; if the lithium battery cover plate 50 has no sealing problem (including secondary detection that the mass spectrometer 20 does not detect helium), the lithium battery cover plate is moved to the station where the lithium battery cover plate leakage detection mechanism 5 is located by the lithium battery cover plate moving manipulator 9. In order to separate the lithium battery cover plate 50 from the upper pumping template 34 (to remove money from the upper pumping template 34) smoothly, i.e. in order to prevent the lithium battery cover plate 50 from adhering to the downward side of the upper pumping template 34, the lithium battery plate dropping-assisting device 345 assists dropping, specifically: under the restoring force of the pushing column acting spring 3454, the dropping-assisting pushing column 3453 of the lithium battery panel moves downwards to push the lithium battery cover plate 50, so that the lithium battery cover plate 50 falls into the lithium battery cover plate detection accommodating cavity 3222, and the lithium battery cover plate moving manipulator 9 reliably and completely extracts the lithium battery cover plate.

After the lithium battery cover plate air tightness alternation detection mechanism 3 detects the lithium battery cover plate 50 with unqualified air tightness, the lithium battery cover plate transferring manipulator 9 driven by the lithium battery cover plate transferring manipulator left and right displacement driving mechanism 8 moves to the station where the lithium battery cover plate air-tightness detection bearing frame 32 is located, and at this time, the lithium battery cover plate air-tightness detection bearing frame 32 is located at the front side shown in fig. 7 (as shown by the position where the right lithium battery cover plate air-tightness detection bearing frame 32 is located in the position state shown in fig. 7), in this state, the lithium battery which is unqualified in air tightness detection is transferred to the station where the output mechanism 4 of the unqualified air tightness detection product of the lithium battery cover plate is positioned by the manipulator 9 for transferring lithium battery cover plate shown in figure 3 and figure 1, and the lithium battery cover plate 50 with qualified air tightness detection is moved to the station where the lithium battery cover plate electric leakage detection mechanism 5 is located.
The applicant makes the following description on the extraction and release of the lithium battery cover plate 50 qualified in the air tightness detection by the lithium battery cover plate transferring manipulator 9: that is, the following description will be made of a process in which the lithium battery cover plate transfer robot 9 extracts the lithium battery cover plate 50 at the station where the lithium battery cover plate airtightness alternation detection mechanism 3 is located and transfers and releases the extracted lithium battery cover plate 50 to the lithium battery cover plate leakage detection mechanism 5.
Before explaining the working process of the lithium battery cover plate moving manipulator 9, the left and right displacement driving mechanism 8 of the lithium battery cover plate moving manipulator is explained, after the separation of the lithium battery cover plate 50 and the detection of the left and right displacement driving mechanism 8 of the lithium battery cover plate moving manipulator are completed, the electric controller 30 sends a working instruction to the left and right displacement driving motor 84 of the manipulator, the left and right displacement driving motor 84 of the manipulator works, the left and right displacement driving motor shaft of the manipulator drives the left and right displacement driving wheel shaft 861 of the manipulator through the left and right displacement driving wheel shaft coupler 86111 of the manipulator, the left and right displacement driving wheel shaft 861 of the manipulator drives the left and right displacement belt 85 of the manipulator through the left and right displacement belt fixing block 98 of the manipulator connected with the left and right displacement belt 85 of the manipulator to drive the guide slider fixing plate 91, the upper and lower guide blocks 92a and 92b move along the guide block guide 831, for example, to the position shown in fig. 1, so that the lithium battery cover plate transfer robot 9 picks up the lithium battery cover plate 50 whose airtightness has been detected at this position. The method comprises the following steps: under the instruction of the electric controller 30, the lifting push plate actuating cylinder 97 works, the lifting push plate actuating cylinder 972 pushes the lifting push plate 93 downwards, when the push plate upper limit position signal collector trigger block 932 touches the lifting push plate lower limit position signal collector 9131, the lifting push plate lower limit position signal collector 9131 feeds back a signal to the electric controller 30, the lifting push plate actuating cylinder 97 stops working by the electric controller 30, the four pairs of suckers 96 at the moment are respectively contacted with the lithium battery cover plate 50 still in the lithium battery cover plate detection accommodating cavity 3222, and under the working of a negative pressure generating device, namely a negative pressure generator such as a vacuum pump or the like, the suckers 96 are sucked through a pipeline to generate negative pressure so as to suck the lithium battery cover plate 50. Next, the lifting push plate actuating cylinder 97 is operated in reverse, so that the lithium battery cover plate 50 sucked by the suction cup 96 leaves the lithium battery cover plate detection accommodating cavity 3222, until the push plate upper limit position signal collector trigger block 932 touches the lifting push plate upper limit position signal collector 912, the lifting push plate upper limit position signal collector 912 feeds back a signal to the electric controller 30, and the lifting push plate actuating cylinder 97 is stopped by the electric controller 30. Next, when the manipulator left and right displacement driving motor 84 works in the reverse direction with respect to the aforementioned working direction, the manipulator left and right displacement belt 85 drives the entire lithium battery cover plate transfer manipulator 9 to move to the station where the lithium battery cover plate leakage detection mechanism 5 is located in the state of sucking the lithium battery cover plate 50, so as to detect whether the lithium battery cover plate 50 is in a leakage state or not.
When the manipulator 9 reaches the position in front of the leakage detection mechanism 5, specifically, the left and right output belts 64 and 67 for leakage detection of lithium battery cover shown in fig. 1, under the control of the PLC of the electrical controller 30, the negative pressure generator, i.e., the negative pressure generator, such as a vacuum pump or other similar device, stops working to make the suction cup 96 in positive pressure and make the four lithium battery covers 50 previously sucked by the suction cup 96 simultaneously released onto the left and right output belts 64 and 67 for leakage detection of lithium battery cover, then the lifting push plate actuates the action cylinder 972 to ascend, when the trigger block 932 of the limit position signal collector on the push plate touches the limit position signal collector 912 on the lifting push plate, the limit position signal collector 912 on the lifting push plate sends a signal to the electrical controller 30, the electric controller 30 drives the motor 611 to work by the lithium battery cover plate electric leakage detection qualified product conveying belt, so that the four lithium battery cover plates 50 positioned on the lithium battery cover plate electric leakage detection qualified product left and right output belts 64 and 67 correspond to the lithium battery cover plate bearing plate 53. When the electric leakage detection qualified product conveying belt driving motor 611 stops working, the electric controller 30 sends an instruction to enable the supporting plate lifting cylinder 542 to work, the supporting plate lifting cylinder column 5421 extends upwards, namely outwards towards the cylinder body, and pushes the lithium battery cover plate supporting plate 53 with the released lithium battery cover plate 50 to extend upwards until the lithium battery cover plate 50 is located in the lithium battery cover plate limiting block groove 5511 of the lithium battery cover plate limiting block 551 corresponding to the lithium battery cover plate limiting plate 55, namely the four lithium battery cover plates 50 are located in the lithium battery cover plate limiting block groove 5511 and the supporting plate lithium battery cover plate accommodating cavity 5311 through the matching of the four lithium battery cover plate limiting blocks 551 and the lithium battery cover plate supporting plate 53. At this time, since the lithium battery cover plate supporting plate 53 moves upward, the signal of the lithium battery cover plate 50 is collected by the limiting plate position signal collector 552 and fed back to the electric controller 30, and the electric controller 30 sends out the operating instructions to the four pushing plate lifting acting cylinders 571 in sequence, because the test of the four lithium battery cover plates 50 is performed one by one, and because the test mode of the four pushing plate lifting acting cylinders 571 is completely the same, the applicant only performs the following test on the front first lithium battery cover plate 50.
Under the operation of the push plate lifting cylinder 571, the push plate 572 moves downward by the downward movement of the push plate lifting cylinder 5712, the push plate 572 drives the electric leakage detection electrode fixing block 573, the electric leakage detection electrode fixing block 573 drives the pair of electric leakage detection electrodes 58 to move downward, one of the electric leakage detection electrodes 58 contacts the electrode plate 502 of the lithium battery cover plate 50, the other of the electric leakage detection electrodes 58 contacts the main body 501 of the lithium battery cover plate 50 insulated and isolated by the insulating material, the electrode plate 502 is insulated and separated from the main body 501 by the insulating sheet such as plastic (not conducted with each other), if there is no conduction between the electrode plate 502 and the main body 501 (i.e., the lithium battery cover plate main body), it indicates that there is no electric leakage, otherwise, the electric leakage is known by the electric controller 30. It should be noted that: the degree of the downward movement and the upward movement of the push plate lift cylinder columns 5712 of the push plate lift cylinder 571 is determined by the push plate lift cylinder vertical displacement controller 5711 controlled by the electric controller 30.
After the leakage detection mechanism 5 for the lithium battery cover plate finishes the leakage detection of the lithium battery cover plate 50, the leakage detection electrode 58 goes upward and leaves the lithium battery cover plate 50, the bearing plate lifting action cylinder 542 goes downward to drive the lithium battery cover plate bearing plate 53 to go downward, so that the two ends of the lithium battery cover plate 50 which finishes the leakage detection are placed on the left and right output belts 64 and 67 of the qualified product of the leakage detection of the lithium battery cover plate, and the electric controller 30 sends an instruction to enable the conveying belt of the qualified product of the leakage detection of the lithium battery cover plate to drive the motor 611 to work until the left and right output belts 64 and 67 of the qualified product of the leakage detection of the lithium battery cover plate move; when the unqualified lithium battery cover plate 50 with electric leakage which is detected before passes through the position corresponding to the lithium battery cover plate electric leakage detection unqualified product taking mechanism 7, the left and right output belts 64 and 67 of the lithium battery cover plate electric leakage detection qualified product are suspended at the position so as to be used for the lithium battery cover plate electric leakage detection unqualified product taking mechanism 7 to take away, otherwise, the lithium battery cover plate electric leakage detection unqualified product is directly output.
The applicant makes the following description on the working process of the foregoing lithium battery cover plate leakage detection defective product taking-off mechanism 7: because the electrical controller 30 has a PLC, and the PLC automatically records whether any one of the four lithium battery cover plates 50 from 1 st to 4 th has a leaking lithium battery cover plate, when the leaking lithium battery cover plate 50 passes through the lithium battery cover plate leakage detection defective product removing mechanism 7 in the process of outputting the lithium battery cover plate leakage detection defective product left and right output belts 64 and 67 in the aforementioned leakage test, the electrical controller 30 sends an instruction to stop working to the lithium battery cover plate leakage detection defective product conveying belt driving motor 611 and simultaneously sends a working instruction to the defective product suction nozzle fixing plate lifting action cylinder 77 and causes a negative pressure generating device such as a vacuum pump or other similar devices connected with the defective product suction pipe 79 through a pipeline to work. Under the operation of the lifting cylinder 77 of the unqualified product suction nozzle fixing plate, the sliding plate 7741 drives the suction nozzle fixing plate support 781, the unqualified product suction nozzle fixing plate 78 and the pair of unqualified product suction nozzles 79 to move downwards to the extent that the sliding plate ram 7741 touches the sliding plate descending limit position signal collector 7731, the pair of unqualified product suction nozzles 79 touch the creepage lithium battery cover plate 50 and suck the creepage lithium battery cover plate under the action of negative pressure, then the unqualified product suction nozzle fixing plate lifting cylinder 77 works reversely to enable the pair of unqualified product suction nozzles 79 to move upwards in the state of sucking the creepage lithium battery cover plate 50, the degree of the upward displacement is determined that the upper end surface of the sliding plate 774 touches the sliding plate ascending limit position signal collector 7721, at this time, the sliding plate ascending limit position signal collector 7721 feeds back signals to the electric controller 30, the electric controller 30 feeds the signals to the linear cylinder 75, the linear cylinder slider 76, the unqualified product suction nozzle fixing plate lifting cylinder base 771, the unqualified product suction nozzle fixing plate lifting cylinder 77, the sliding plate 774, the suction nozzle fixing plate supporting frame 781, the unqualified product suction nozzle fixing plate 78, the pair of unqualified product suction nozzles 79 and the lithium battery cover plate 50 which is still in the electric leakage sucked by the pair of unqualified product suction nozzles 79 move rightwards to the upper part of the unqualified product output mechanism 4 corresponding to the air tightness of the lithium battery cover plate, at the moment, the linear cylinder slider 76 collides with the left slide rail base signal collector 731, a signal is given to the electric controller 30 by the electric controller 30, and the linear cylinder 75 is suspended by the electric controller 30. Next, the lifting cylinder 77 of the nozzle fixing plate of the defective product operates in reverse, and in the reverse process, until the signal collector 7731 of the slide plate descending limit position is hit by the slide plate striker 7741, a signal is fed back to the electric controller 30, and the electric controller 30 sends a signal to the negative pressure generating device, so that the pair of nozzles 79 of the defective product are in positive pressure, and the leaked lithium battery cover plate 50 is released to the output mechanism 4 of the detected product with the defective lithium battery cover plate airtightness and is output by the output mechanism. Then, according to the reverse process, the linear cylinder 75 makes the lifting cylinder 77 of the unqualified product suction nozzle fixing plate move left to the upper main part of the left and right output belts 64 and 67 corresponding to the qualified product of the leakage detection of the lithium battery cover plate, the left displacement degree of the linear cylinder 75 is based on the condition that the linear cylinder slide block 76 touches the right slide rail seat signal collector 741, when the linear cylinder is collided, the linear cylinder gives a signal to the electric controller 30, the electric controller 30 gives the conveying belt driving motor 611 to the qualified product of the leakage detection of the lithium battery cover plate again to work, the qualified lithium battery cover plate 50 is output, otherwise, the above-mentioned way is repeated to be taken away by the unqualified product of the leakage detection of the lithium battery cover plate taking-away mechanism 7.
