Description
Technical Field
The invention belongs to the technical field of lithium battery part detection machinery, and particularly relates to a manipulator driving structure of a lithium battery cover plate testing machine.
Background
The foregoing lithium battery mainly refers to, but is not limited to, a lithium battery used in an electric vehicle (also referred to as a "new energy vehicle"). As known in the art, a lithium battery is composed of a case, a lithium battery cell (composed of a plurality of positive and negative electrode sheets separated by a separator in an insulating manner) provided in a case cavity of the case, and a lithium battery cover plate as a 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 widely applied to electric automobiles, electric bicycles and even various hardware tools in industry.
The aforementioned lithium battery cover plate is an important part of the structural system of the lithium battery and is not known in the published chinese patent literature, such as CN203721782U (power lithium battery cover plate), CN203871392U (integrated high-rivet type lithium battery cover plate), CN104466043a (a pole type lithium battery cover plate and pole type lithium battery using the same), CN105810857a (a lithium battery upper cover assembly), CN202308090U (pole type lithium battery cover plate) and CN102339959a (pole type lithium battery cover plate), and the like.
In order to ensure the quality of the lithium battery and to embody its safety during use, it is often necessary to detect the housing, the housing cover plate and the lithium battery cell. Taking a lithium battery cover plate as an example, the requirements on the air tightness and the anti-creeping performance of an 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 electrical insulation part is deficient, safety accidents can be caused.
Technical information about devices for detecting lithium battery parts, such as CN209311004U (a power battery cover plate air tightness detection device), CN207280669U (cover plate (i.e., lithium battery cover plate) pressure test device), CN101915703B (pressure resistance test device for lithium battery case), CN208721347U (a power battery cover plate air tightness detection mechanism), CN202693423U (high-precision lithium battery cover plate explosion test device) and CN206563639U (a power battery cover plate helium leak detection machine) and CN213397503U (a device for battery cover plate air tightness detection device), etc., are also visible in the published chinese patent literature.
As a lithium battery cover plate testing machine, in order to embody the integrity, it is generally required to transfer a lithium battery cover plate to be tested from a work piece (i.e., a "lithium battery cover plate", hereinafter the same) input station to a station where a certain test item is located (e.g., an "air tightness test station"), then transfer a work piece completed with a certain test item such as the aforementioned air tightness test item to a station where another test item such as an electric leakage test item is located (also referred to as a "station where an insulation test item is located"), and so on. Therefore, an automatic workpiece transfer device such as a lithium battery cover plate transfer manipulator is necessary on the lithium battery cover plate testing machine, otherwise, if the lithium battery cover plate is manually transferred from the first station to the last station by an on-line operator, the detection efficiency is affected, and the action continuity of the lithium battery cover plate testing machine is affected. It is known that, if the manipulator reciprocates between the first and last stations, i.e., the first and last stations, the manipulator reciprocation displacement driving mechanism must be ensured, however, the technical teaching related to the device for detecting the lithium battery cover plate is not given in the above-mentioned patent documents, and the technical proposal to be described below is generated in the background.

Before the lithium battery cover plate transferring manipulator 9 transfers the four lithium battery cover plates 50 on the lithium battery cover plate inspection input mechanism 2 to the lithium battery cover plate air tightness alternate detection mechanism 3, the lithium battery cover plate air tightness alternate detection mechanism 3 has two same structures, so as to embody alternate detection and achieve the purpose of improving detection efficiency. Now, taking the state shown in fig. 7 as an example, one lithium battery cover plate air tightness alternation detection mechanism 3 on the left side is in the air tightness detection process, and one lithium battery cover plate air tightness alternation detection mechanism 3 on the right side is in a state of receiving four lithium battery cover plates 50 extracted from a group of lithium battery cover plate separating devices 28 of the lithium battery cover plate inspection input mechanism 2 by the lithium battery cover plate transfer manipulator 9. In order to achieve this state, the electric controller 30 makes the air tightness detection carrier forward and backward displacement driving action cylinder 313 work, so that the air tightness detection carrier forward and backward displacement driving action cylinder block 3132 drives the air extraction lower template 321 and the lithium battery cover plate upper template 322 to be tested to forward displace to be in the state shown in fig. 7, when the front end face of the air extraction lower template 321 touches the air extraction lower template front position signal collector 3142, the air extraction lower template front position signal collector 3142 feeds back a signal to the electric controller 30, so that the air tightness detection carrier forward and backward displacement driving action cylinder 313 pauses to work, and the lithium battery cover plate moving manipulator 9, which will be described in detail below, guides four lithium battery cover plates 50 into the four lithium battery cover plate detection accommodating cavities 3222 simultaneously. It should be noted that: the left-right displacement of the lithium battery cover plate transferring manipulator 9 between the stations is driven by a left-right displacement driving mechanism 8 of the lithium battery cover plate transferring manipulator controlled by a PLC (programmable logic controller) of the electric controller 30.
After the four lithium battery cover plate detection accommodating chambers 3222 of the lithium battery cover plate upper template 322 to be detected are respectively connected to the lithium battery cover plate 50, signals (to be mentioned further 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 instructions to enable the air tightness detection bearing frame to move forward and backward to drive the action cylinder 313 to move reversely relative to the above, the air tightness detection bearing frame 32 of the lithium battery cover plate is enabled to move backward to the position below the air suction upper template 34, the degree of the backward movement of the air tightness detection bearing frame 32 of the lithium battery cover plate is based on the condition that the rear end face of the air suction lower template 321 touches the rear position signal collector 3152 of the air suction lower template, when touching, signals are fed back to the electric controller 30, and meanwhile, the electric controller 30 enables a pair of upper template pressing plate lifting action cylinders 363 to work, the upper template pressing plate 361 is pushed down by the upper template lifting action cylinder 3631, the upper template pressing plate 361 is pushed by the upper template 35 to move backward together with the upper template 34, and the lithium battery cover plate upper template 34 is enabled to close to the four lithium battery cover plates to be detected and the lithium battery cover plate 50 are respectively accommodated in the four lithium battery cover plates 3222.
In the above state, because the upper plate 34 is pumped and the upper plate 322 of the lithium battery cover plate to be tested is clamped, the signal is generated by the matching of the template clamping signal collector 349 and the template clamping signal collector 3226, the signal is fed back to the electric controller 30 by the template clamping signal collector 3226, the electric controller 30 sends a command to the vacuumizing mechanism 10, the vacuumizing mechanism 10 works, that is, the vacuumizing mechanism 10 starts vacuumizing, at the same time, the air guide block 334 is correspondingly moved backwards due to the backward movement of the lower pumping template 321, the air guide block vent holes 3341 on the air guide block 334 are butted with the air valve 333, When the air in the air storage tank (the helium air storage tank in the invention) is led in from the detection air inlet pipe matching hole 3322 through the pipeline, the air is sequentially led in from the detection air outlet hole 3351 of the detection air distribution seat 335, the lithium battery cover plate detection accommodating cavity air guide pipe 337, the lithium battery cover plate detection accommodating cavity air guide pipe matching hole 3223, the accommodating cavity air guide groove 3224 and the accommodating cavity air outlet hole 3225 through the air guide block matching hole 3341, the detection air transition inlet pipe 336 and the detection air outlet hole 336, if the lithium battery cover plate 50 still positioned in the lithium battery cover plate detection accommodating cavity 3222 has poor tightness, the air leakage condition exists, Under the operation of the vacuumizing mechanism 10 connected with the air extraction connector 341 of the air extraction upper template through a pipeline, the gas (helium) can be led out from the air outlet hole 3225 of the accommodating cavity through the lithium battery cover plate 50, the air extraction upper template air cavity 343 on the air extraction upper template 34, the small air cavity communicating air passage 344 of the air extraction upper template, the air passage 342 of the air extraction upper template and the air extraction connector of the air extraction upper template through the pipeline, the pressure value of the vacuumizing mechanism 10 can be reduced below the set value required by the process, so that the vacuumizing mechanism 10 feeds back signals to the electric controller 30, and as long as any one of the four lithium battery cover plates 50 has a sealing problem, the four lithium battery cover plates are not allowed to flow into the following steps. On the contrary, when the sealing problem does not exist in the four lithium battery cover plates 50, in order to fully ensure the quality, the vacuum pump 40 performs the vacuum detection again, specifically: under the operation of the evacuation pump 40, the gas in the pipeline connected to the evacuation mechanism 10 is extracted and supplied to the mass spectrometer 20, and if the mass spectrometer 20 detects helium in the gas, a signal is fed back to the electrical controller 30 by the mass spectrometer 20. After the detection, the upper template frame pressing device 36 moves the upper air extracting template 34 upward, and then the lithium battery cover plate air tightness detection carrier frame 32 moves forward to the state shown in fig. 7. If the sealing problem exists in the lithium battery cover plate 50, the lithium battery cover plate transferring manipulator 9 transfers the lithium battery cover plate to the lithium battery cover plate air tightness disqualification detection output mechanism 4, the lithium battery cover plate air tightness disqualification detection output mechanism 4 outputs the lithium battery cover plate air tightness disqualification detection output mechanism, and the lithium battery cover plate 50 with the sealing problem is detected by picking type secondary or multiple times of sealing screening after the lithium battery cover plate is collected until the finally confirmed lithium battery cover plate 50 with the sealing problem is detected; if the lithium battery cover 50 does not have a sealing problem (including the mass spectrometer 20 not detecting the secondary detection of helium), the lithium battery cover is transported by the lithium battery cover transporting manipulator 9 to the station where the lithium battery cover leakage detecting mechanism 5 is located. In order to separate the lithium battery cover plate 50 from the air extraction upper plate 34 (remove the banknote from the air extraction upper plate 34) in a refreshing manner, that is, in order to avoid the lithium battery cover plate 50 from adhering to the downward facing side of the air extraction upper plate 34, the above-mentioned lithium battery plate falling-off assisting device 345 assists in falling off, specifically: under the restoring force of the pushing post acting spring 3454, the falling-off assisting pushing post 3453 of the lithium battery panel is enabled to descend and 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 transporting manipulator 9 is reliably and completely extracted.

After the lithium battery cover plate air tightness alternate detection mechanism 3 detects the lithium battery cover plate 50 with unqualified air tightness, the lithium battery cover plate moving manipulator 9 driven by the left-right displacement driving mechanism 8 of the lithium battery cover plate moving manipulator moves to a station where the lithium battery cover plate air tightness detection bearing frame 32 is located, the lithium battery cover plate air tightness detection bearing frame 32 at this time is located in front of the position shown in fig. 7 (the position where the lithium battery cover plate air tightness detection bearing frame 32 is located on the right side of the position state shown in fig. 7), in this state, the lithium battery cover plate moving manipulator 9 shown in fig. 3 and fig. 1 moves the lithium battery with unqualified air tightness detection to the station where the lithium battery cover plate air tightness unqualified detection product output mechanism 4 is located, and moves the lithium battery cover plate 50 with qualified air tightness detection to the station where the lithium battery cover plate electric leakage detection mechanism 5 is located.
The applicant describes the extraction and release of the lithium battery cover 50 qualified for the air tightness detection by the lithium battery cover transferring manipulator 9 as follows: that is, the process of extracting the lithium battery cover 50 at the station where the lithium battery cover airtightness alternation detecting mechanism 3 is located by the lithium battery cover transfer robot 9 and transferring and releasing the extracted lithium battery cover 50 to the lithium battery cover leakage detecting mechanism 5 is described as follows.
Before describing the operation of the lithium battery cover plate transferring manipulator 9, describing the lithium battery cover plate transferring manipulator left-right displacement driving mechanism 8, after completing the separation of the lithium battery cover plate 50 and the detection of the lithium battery cover plate transferring manipulator left-right displacement driving mechanism 8, the electric controller 30 sends an operation command to the manipulator left-right displacement driving motor 84, the manipulator left-right displacement driving motor 84 operates, the manipulator left-right displacement driving motor shaft drives the manipulator left-right displacement driving wheel axle 861 through the manipulator left-right displacement driving wheel axle coupling 86111, the driving wheel shaft 861 is driven by the left and right displacement of the manipulator to drive the driving wheel 86 to drive the left and right displacement belt 85 by the left and right displacement belt 85, the guide block fixing plate 91 is driven by the left and right displacement belt fixing block 98 of the manipulator connected with the left and right displacement belt 85, and the upper and lower guide blocks 92a and 92b move along the guide block guide bar 831, for example, to the position shown in fig. 1, so that the lithium battery cover plate transfer manipulator 9 extracts the lithium battery cover plate 50 with the air tightness detection completed at the position. The method specifically 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 column 972 pushes the lifting push plate 93 downwards, when the trigger block 932 of the limiting position signal collector on the push plate touches the limiting position signal collector 9131 of the limiting position signal collector under the lifting push plate, the limiting position signal collector 9131 under the lifting push plate feeds back signals to the electric controller 30, the electric controller 30 stops working the lifting push plate actuating cylinder 97, 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 vacuumizing pump or the like, the sucker 96 is sucked through a pipeline, so that the sucker generates negative pressure to suck the lithium battery cover plate 50. Then, the lifting-pushing-plate actuating cylinder 97 is operated in the reverse direction, so that the lithium battery cover 50 in the state of being sucked by the suction cup 96 is separated from the lithium battery cover detection accommodating chamber 3222, and when the triggering block 932 of the limiting-position signal collector on the pushing plate touches the limiting-position signal collector 912 on the lifting pushing plate, the limiting-position signal collector 912 on the lifting pushing plate feeds back a signal to the electric controller 30, and the electric controller 30 stops the lifting-pushing-plate actuating cylinder 97. Next, under the reverse operation of the manipulator left-right displacement driving motor 84 with respect to the aforementioned operation direction, the manipulator left-right displacement belt 85 drives the whole lithium battery cover plate transferring manipulator 9 to operate to the station where the lithium battery cover plate leakage detecting mechanism 5 is located in a state of sucking the lithium battery cover plate 50, so as to detect whether the lithium battery cover plate 50 is leaked or not.
When the lithium battery cover transfer robot 9 reaches the position in front of the lithium battery cover leakage detection mechanism 5 under the control of the PLC of the electric controller 30, specifically, the position in front of the left and right output belts 64, 67 of the lithium battery cover leakage detection qualified product shown in fig. 1 (front end), the negative pressure generator, that is, the negative pressure generator such as a vacuum pump or the like, stops working, makes the suction cup 96 at positive pressure, makes the four lithium battery covers 50 sucked by the suction cup 96 simultaneously release to the left and right output belts 64, 67 of the lithium battery cover leakage detection qualified product, then the lifting push plate actuation cylinder 972 rises, and when the limit position signal collector 912 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 gives a signal to the electric controller 30, and the electric controller 30 makes the lithium battery cover plate conveying belt driving motor 611 work, so that the four lithium battery covers 50 located on the left and right output belts 64, 67 of the lithium battery cover plate correspond to the lithium battery cover plate 53. When the lithium battery cover plate leakage detection qualified product conveying belt driving motor 611 stops working, the electric controller 30 sends out an instruction to enable the support plate lifting action cylinder 542 to work, the support plate lifting action cylinder column 5421 stretches upwards, namely stretches out of the cylinder body and pushes the lithium battery cover plate support plate 53 with the released lithium battery cover plate 50 upwards until the lithium battery cover plate 50 stretches upwards in the lithium battery cover plate upper limiting block groove 5511 corresponding to the lithium battery cover plate limiting block 551 of the lithium battery cover plate limiting plate 55, namely four lithium battery cover plates 50 are limited in the lithium battery cover plate upper limiting block groove 5511 and the support plate lithium battery cover plate accommodating concave cavity 5311 by matching of four lithium battery cover plate limiting blocks with the lithium battery cover plate support plate 53. At this time, the signals of the lithium battery cover plate 50 are collected by the limit plate position signal collector 552 and fed back to the electric controller 30 due to the upward movement of the lithium battery cover plate supporting plate 53, and the electric controller 30 sequentially sends out the working instructions to the four pushing plate lifting action cylinders 571, because the tests of the four lithium battery cover plates 50 are performed one by one, and because the test modes of the four pushing plate lifting action cylinders 571 are completely the same, the applicant only describes the test of the first lithium battery cover plate 50 in front below.
Under the operation of the push plate lifting cylinder 571, the push plate 572 is moved downward by the downward movement of the push plate lifting cylinder post 5712, the push plate 572 moves the leakage detection electrode fixing block 573, the leakage detection electrode fixing block 573 moves the pair of leakage detection electrodes 58 downward, one of the pair of leakage detection electrodes 58 is brought into contact with the electrode sheet 502 of the lithium battery cover 50, the other leakage detection electrode of the pair of leakage detection electrodes 58 is brought into contact with the body 501 of the lithium battery cover 50 insulated and isolated by an insulating material, the electrode sheet 502 and the body 501 are separated (not conducted with each other) by an insulating sheet such as plastic, and if the electrode sheet 502 and the body 501 (i.e., the lithium battery cover body) are not conducted, the leakage condition is indicated to be absent, otherwise, the leakage condition is known by the electric controller 30. It should be noted that: the degree of downward movement and upward stroke of the push plate lifting cylinder column 5712 of the push plate lifting cylinder 571 is determined by the controller 5711, which is controlled by the electric controller 30, for the upward and downward displacement of the push plate lifting cylinder.
After the above-mentioned lithium battery cover plate leakage detection mechanism 5 completes the leakage detection of the lithium battery cover plate 50, the leakage detection electrode 58 goes up and leaves the lithium battery cover plate 50, the above-mentioned supporting plate lifting action cylinder 542 goes down to drive the lithium battery cover plate supporting plate 53 to go down, so that the two ends of the lithium battery cover plate 50 completing the leakage detection are placed on the left and right output belts 64, 67 of the qualified product for lithium battery cover plate leakage detection, and the electric controller 30 sends out an instruction to make the qualified product for lithium battery cover plate leakage detection conveyor belt driving motor 611 work until the left and right output belts 64, 67 of the qualified product for lithium battery cover plate leakage detection move; when the previously detected unqualified lithium battery cover 50 with electric leakage passes through the position corresponding to the lithium battery cover electric leakage detection unqualified product taking-off mechanism 7, the left and right output belts 64 and 67 of the lithium battery cover electric leakage detection unqualified product are suspended at the position so as to be taken off by the lithium battery cover electric leakage detection unqualified product taking-off mechanism 7, and otherwise, the lithium battery cover electric leakage detection unqualified product is directly output.
The applicant describes the working process of the lithium battery cover plate leakage detection defective product taking-out mechanism 7 as follows: since the electric controller 30 has a PLC and the PLC automatically records the presence or absence of electric leakage of any one of the 1 st to 4 th lithium battery cover plates 50, the electric controller 30 issues an instruction to stop operation to the lithium battery cover plate electric leakage detection acceptable product conveyor belt driving motor 611 and simultaneously issues an operation instruction to the unacceptable product suction nozzle fixing plate lifting and lowering action cylinder 77 and operates a negative pressure generating device such as a vacuum pump or the like connected to the unacceptable product suction pipe 79 through a pipe line in the course of outputting the left and right output belts 64, 67 of the lithium battery cover plate electric leakage detection acceptable product, when the lithium battery cover plate 50 of electric leakage detected in the electric leakage test described above passes through the lithium battery cover plate electric leakage detection acceptable product taking-off mechanism 7. Under the operation of the defective suction nozzle fixing plate lifting action cylinder 77, the slide plate 7741 drives the suction nozzle fixing plate support frame 781, the defective suction nozzle fixing plate 78 and the pair of defective suction nozzles 79 to move downward to such an extent that the slide plate striker 7741 touches the slide plate descending limit position signal collector 7731, the pair of defective suction nozzles 79 at this time are brought into contact with the aforementioned leaked lithium battery cover plate 50 and sucked under the action of negative pressure, and then the defective suction nozzle fixing plate lifting action cylinder 77 is operated reversely to displace the pair of defective suction nozzles 79 upward in a state of sucking the leaked lithium battery cover plate 50, The upward displacement is performed to the extent that the upper end surface of the slide plate 774 touches the slide plate upward limit position signal collector 7721, at this time, the slide plate upward limit position signal collector 7721 feeds back a signal to the electric controller 30, the electric controller 30 feeds the linear cylinder 75, the linear cylinder block 76 together with the reject nozzle fixing plate lifting cylinder block 771, the reject nozzle fixing plate lifting cylinder 77, the slide plate 774, the nozzle fixing plate support frame 781, the reject nozzle fixing plate 78, the pair of reject nozzles 79, and the lithium battery cover plate 50 still in the electric leakage sucked by the pair of reject nozzles 79 are moved rightward to the upper side corresponding to the lithium battery cover plate airtight reject output mechanism 4, at this time, the linear cylinder block 76 collides with the left rail seat signal collector 731, and the signal is given to the electric controller 30, so that the electric controller 30 stops the linear cylinder 75. Then, the defective suction nozzle fixing plate lifting cylinder 77 is operated in the reverse direction, and the signal is fed back to the electric controller 30 by the signal collector 7731 until the slide plate lowering limit position is hit by the slide plate hit head 7741 in the reverse direction, and the electric controller 30 feeds the signal to the negative pressure generating device, so that the pair of defective suction nozzles 79 are brought into positive pressure to release the leaked lithium battery cover 50 to the lithium battery cover airtightness defective inspection output mechanism 4 and output the leaked lithium battery cover airtightness defective inspection output mechanism. then, according to the reverse process described above, the linear cylinder 75 moves the reject nozzle fixing plate lifting action cylinder 77 to the left to the upper main position corresponding to the left and right output belts 64, 67 of the above-mentioned lithium battery cover plate leakage detection reject, the extent to which the linear cylinder 75 moves to the left is determined by the fact that the linear cylinder slider 76 touches the right slide rail seat signal collector 741, the signal is given to the electric controller 30 when the impact is timely, the electric controller 30 again conveys the lithium battery cover plate leakage detection reject to the belt driving motor 611 to operate, the qualified lithium battery cover plate 50 is output, and otherwise, the reject detection reject taking mechanism 7 takes off the reject detection by the lithium battery cover plate leakage detection in the above-mentioned manner.
