After the second movable block 35 contacts the detection plate 31, the third channel 351 and the fourth channel 311 are connected correspondingly. The telescopic rod of the second lifting drive mechanism 33 passes through the second frame 30 and is fixedly connected to the second detection cover plate 34. After the detection plate 31 is displaced into the second detection inner cavity 32, the second detection cover plate 34 corresponds to the detection plate 31. The second detection cover plate 34 is provided with a second upper positioning groove 342 and a second exhaust channel 341.

A feeding channel 1 is formed between the first frame 20 and the second frame 30.

[0029] In order to realize the rotation inspection processing of multiple inspection stations and improve the inspection efficiency, the bottom surface of the first inspection inner cavity, the bottom surface of the second inspection inner cavity and the bottom surface of the feeding channel are assembled together to form an installation plane 300, and a plurality of mutually parallel linear displacement drive devices 6 are arranged on the installation plane 300, and the two displacement sliders 611 of each linear displacement drive device 6 are respectively installed with an inspection platform and an inspection plate, and the first lifting drive mechanism 23 and the second lifting drive mechanism 33 are both arranged in plurality, and the first inspection cover plate 24 and the second inspection cover plate 34 are both arranged in plurality, and the piston rod end of each first lifting drive mechanism 23 is respectively fixedly connected to each first inspection cover plate 24, and the piston rod end of each second lifting drive mechanism 33 is respectively fixedly connected to each second inspection cover plate 34, and each first inspection cover plate 24 and each second inspection cover plate 34 respectively corresponds to the position of each linear displacement drive device 6.

The rotating shaft of the machine is fixedly connected to the ends of the two ball screws, the ball sliders of the two ball screws are fixedly connected to the two sliders, and the detection platform and the detection plate are fixed on the two sliders respectively. The servo motor is powered on and started, and the rotating shaft rotates to drive the ball screw to rotate, so that the ball slider is displaced, and the displacement of the ball slider drives the translation of the slider, thereby realizing the reciprocating translation of the detection platform and the detection plate, so as to move the detection platform to the feeding channel or to the first detection inner cavity, and to move the detection plate to the feeding channel or to the second detection inner cavity.

[0031] After the inspection of the workpiece formed between the first inspection cover plate and the inspection platform is completed, the inspection platform and the inspection plate with the inspected workpiece are driven to move to the position of the feeding channel by the linear displacement driving device, and the inspected workpiece in the feeding channel is grabbed by the material taking robot and conveyed to the first product conveying mechanism for conveying qualified products or the second product conveying mechanism for conveying unqualified products. The top cover of the ternary lithium battery to be inspected is placed on the vacant inspection platform and the inspection plate in the feeding channel. After the placement is completed, the linear displacement driving device displaces the inspection plate and the inspection platform with the workpiece to be inspected to the first inspection cover plate and the second inspection cover plate respectively. The detection operation is performed below the plate. However, when the detection work is performed in the second detection cavity, the PLC controller controls the displacement slider of a lateral displacement servo slide to move, so that a material-picking robot picks up the top cover of the ternary lithium battery to be detected from the first product conveying mechanism used for conveying and feeding the product to be detected and conveys it to the second lower positioning groove of the detection platform. The inner wall of the second lower positioning groove 312 is provided with a sealing ring 200, and the sealing ring is used to seal the periphery of the top cover of the ternary lithium battery and the positioning groove.

At this time, when the third channel is connected to the fourth channel, vacuum is performed to extract the air in the second concave cavity, and then helium is flushed into the second concave cavity through the third channel and the fourth channel. Finally, the second air extraction channel extracts air from the second air extraction cavity. During the air extraction process, the gas sensor in the air extraction pipeline of the air extraction pump senses whether there is helium. The gas pump and the gas sensor are both connected to the PLC controller, so the data detected by the gas sensor is sent to the PLC control, and the program setting of the PLC controller is used to judge whether the product is qualified. If the helium extraction is not sensed, it is judged to be qualified. The PLC controller controls the air pump to make the piston rod of the lifting cylinder rise, and the second detection cover plate rises. At this time, the displacement slider of another lateral displacement servo slide moves, so that another material-taking robot takes out the qualified ternary lithium battery top cover to be inspected from the second lower positioning groove of the inspection platform and conveys it to the first product conveying mechanism for conveying and discharging qualified products for inspection;

[0032] If helium is sensed, it is judged as unqualified. The PLC controller controls the air pump to make the piston rod of the lifting cylinder rise, and the second inspection cover plate rises. At this time, the displacement slider of another lateral displacement servo slide moves, so that another material picking robot takes out the unqualified ternary lithium battery top cover to be inspected from the second lower positioning groove of the inspection platform and transports it to the first product conveying mechanism used to inspect and convey unqualified products.
