[0039] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] The following is combined with Figures 1-7 This invention provides a detailed description of a cleaning and full inspection device for a lithium battery cover, comprising:

[0041] Workbench 1 consists of a rectangular frame and a top plate laid on top of the rectangular frame;

[0042] The four-station rotary divider 2 is existing technology. Each rotation angle is 90°. The four-station rotary divider 2 is mounted on the worktable 1 via a support base 3. When the four-station rotary divider 2 is stopped, its four stations are sequentially mounted on the worktable 1 in a counter-clockwise direction: a feeding conveyor belt 4, a back-side cleaning device 5, a back-side photographic detection device 6, and a discharge conveyor belt 7. A front-side cleaning device 11 is mounted above the feeding conveyor belt 4 on the worktable 1. A material barcode scanner 3 is installed on the feeding conveyor belt 4. 8. Specifically used to scan the QR code on the cover of the lithium battery conveyed on the feeding conveyor belt 4. A front-facing photo detection device 12, a 3D contour detection device 13 and a material sorting mechanism 14 are installed on the workbench 1 adjacent to the discharge conveyor belt 7. A rotating disk 8 is concentrically provided on the rotating end face of the four-station rotary divider 2. Both the rotating end of the four-station rotary divider 2 and the middle of the rotating disk 8 adopt a hollow design. A support column 9 is vertically provided on the support base 3. The support column 9 passes through the hollow of the rotating end of the four-station rotary divider 2 and the middle of the rotating disk 8.

[0043] The material transfer mechanism 10 includes a disc 1000, a vertical sliding assembly, four sets of rollers 1005, two sets of lifting cylinders 1006, and four sets of material transfer suction cups 1007. Among them:

[0044] The disc 1000 is concentrically set at the top of the support column 9. The disc 1000 has vertical grooves that penetrate its body on two sides adjacent to the feeding conveyor belt 4 and the discharging conveyor belt 7. The grooves are embedded with irregular sliders 1001.

[0045] Four sets of vertical sliding components are symmetrically located on the outer periphery of the support column 9, and are respectively located at the four stations of the four-station rotary divider 2 when it is in a stopped state. The vertical sliding component includes a slide block 1002, a slide plate 1003, and a tension spring 1004. The bottom of the slide block 1002 is connected to the rotating end face of the four-station rotary divider 2. The slide plate 1003 is vertically slidably connected to the slide block 1002, and a tension spring 1004 is connected between the top of the slide plate 1003 and the bottom of the slide block 1002. The vertical sliding connection is a conventional connection method. In this embodiment, a vertical sliding component consisting of a vertical guide rail and a slider is used for the vertical sliding connection.

[0046] Four sets of rollers 1005 are respectively mounted on the top of the slide plate 1003 in the four sets of vertical sliding components and located on the upper surface of the disc 1000. When the four-station rotary divider 2 is in working state, the four sets of rollers 1005 roll on the upper surface of the disc 1000. When the four-station rotary divider 2 is in a stopped state, any two adjacent sets of rollers 1005 are located on the top surface of the irregular slider 1001 in two irregular grooves on the disc 1000.

[0047] Both sets of lifting cylinders 1006 are mounted on the mounting base on the support column 5. The piston ends of the two sets of lifting cylinders 1006 are respectively connected to the bottom surface of the irregular sliders 1001 in two irregular grooves on the disc 1000. When the piston rods of the two sets of lifting cylinders 1006 extend, the top surface of the irregular sliders 1001 is flush with the top surface of the disc 1000.

[0048] The four sets of material transfer suction cups 1007 are respectively located at the bottom of the slide plates 1003 in the four sets of vertical sliding components.

[0049] The workbench 1 is also equipped with a good product conveyor belt 15, a defective product conveyor belt 16, and a waste recycling bin 36 located below the end of the discharge conveyor belt 7, which are adjacent to the material sorting mechanism 14.

[0050] When the piston rods of the two sets of lifting cylinders 1006 are extended, the top surface of the irregularly shaped slider 1001 is flush with the top surface of the disc 1000. When two sets of rollers 1005 are located on the top surface of the irregularly shaped slider 1001 in two irregularly shaped grooves on the disc 1000 while the four-position rotary divider 2 is stopped, if the piston rods of the two sets of lifting cylinders 1006 retract, the height of the two sets of irregularly shaped sliders 1001 will decrease. At this time, the height of the two sets of rollers 1005 will decrease rapidly under the tension of the tension spring 1004. The two sets of sliding plates 1003 corresponding to these two sets of rollers 1005 will both descend with the material transfer suction cups 1007 at the bottom of their bodies. The height of the two sets of material transfer suction cups 1007 can be lowered to match the conveying height of the feeding conveyor belt 4 and the discharging conveyor belt 7, so as to pick up materials from the feeding conveyor belt 4 and release materials from the discharging conveyor belt 7, respectively.

[0051] The feeding conveyor belt 4 carries the lithium battery cover plate. When the lithium battery cover plate is conveyed to the cleaning position covered by the front cleaning device 11, the feeding conveyor belt 4 stops, and the front cleaning device 11 begins to clean the front of the lithium battery cover plate below it. After cleaning, the feeding conveyor belt 4 starts to convey.

[0052] When the four-station rotary divider 2 is in a stopped state, two sets of rollers 1005 are located on the top surfaces of the irregularly shaped sliders 1001 in two irregularly shaped grooves on the disc 1000. At this time, the piston rods of the two sets of lifting cylinders 1006 are extended, and the top surface of the irregularly shaped sliders 1001 is flush with the top surface of the disc 1000. When the piston rods of the two sets of lifting cylinders 1006 retract, the material transfer suction cup 1007 adjacent to the feeding conveyor belt 4 moves down and grabs the lithium battery cover plate that has been cleaned on the front side of the feeding conveyor belt 4. Then, the piston rods of the two sets of lifting cylinders 1006 extend, and the top surface of the irregularly shaped sliders 1001 remains flush with the top surface of the disc 1000. The four-station rotary divider 2 rotates 90°, and the material transfer suction cup 1007 with the lithium battery cover plate moves to the cleaning area covered by the back cleaning device 5. The back side is cleaned at the feed conveyor belt 4. As the four-station rotary divider 2 rotates, another set of material transfer suction cups 1007, which rotates to be adjacent to the feed conveyor belt 4, also repeats the above-mentioned material grabbing action. After the lithium battery cover plate completes the back side cleaning, the four-station rotary divider 2 rotates 90° again. The lithium battery cover plate that has completed the back side cleaning is transferred by the material transfer suction cups 1007 to the imaging range covered by the back side imaging detection device 6 for imaging detection. After the back side imaging action of the lithium battery cover plate is completed, the four-station rotary divider 2 rotates 90° again. The lithium battery cover plate that has completed the back side imaging detection is then transferred to the top of the discharge conveyor belt 7. Then the piston rods of the two sets of lifting cylinders 1006 retract, and the material transfer suction cups 1007 carry the lithium battery cover plate that has completed the back side imaging detection down and place the lithium battery cover plate on the discharge conveyor belt 7. As the station rotary divider 2 rotates continuously, the components at its four workstations and the two sets of lifting cylinders 1006 cooperate accordingly to achieve continuous operation. When the station rotary divider 2 stops rotating, the material transfer suction cups 1007 at the four workstations respectively pick up materials from the feeding conveyor belt 4, grab lithium battery cover plates for back cleaning, grab lithium battery cover plates for back photograph detection, and place the grabbed lithium battery cover plates on the discharge conveyor belt 7. When the station rotary divider 2 rotates, the four sets of rollers 1005 roll synchronously on the top surface of the disc 1000, and the four sets of material transfer suction cups 1007 synchronously change their workstations.

[0053] When the discharge conveyor belt 7 receives lithium battery cover plates, and when the front-facing imaging detection device 12 and the 3D contour detection device perform corresponding detections on the lithium battery cover plates conveyed by the discharge conveyor belt 7 below, the discharge conveyor belt 7 is in a stopped state. The lithium battery cover plates on the discharge conveyor belt 7 first pass through the imaging range covered by the front-facing imaging detection device 12, which performs front-facing imaging detection on the conveyed lithium battery cover plates. Then, the lithium battery cover plates are conveyed to the scanning detection range covered by the 3D contour detection device 13, which performs 3D contour scanning detection on the lithium battery cover plates. While the 3D contour detection device 13 is performing 3D contour scanning detection, the front-facing imaging detection device 12 is also simultaneously performing front-facing imaging detection on the subsequently conveyed lithium battery cover plates. The lithium battery cover plates on the discharge conveyor belt 7 are completely... After front-facing photo inspection and 3D contour scanning inspection, the material sorting mechanism 14 sorts the lithium battery covers that have completed all processes on the discharge conveyor belt 7 according to the detection structure of the back-facing photo inspection device 6, the front-facing photo inspection device 12 and the 3D contour inspection device 13. The lithium battery covers without quality problems are transferred to the good product conveyor belt 15, and the lithium battery covers with quality problems that can be repaired are transferred to the defective product conveyor belt 16. For lithium battery covers with quality problems that cannot be repaired, the material sorting mechanism 14 sorts them out of alignment, and they fall directly into the waste recycling bin 36 as waste.

[0054] As described above, this application enables automated cleaning and quality inspection of lithium battery cover plates, including the following:

[0055] The back and front of the lithium battery cover can be cleaned by the back cleaning device 5 and the front cleaning device 11, respectively.

[0056] The purpose of taking pictures of the lithium battery cover using the front-facing photo detection device 12 and the back-facing photo detection device 6 is to detect whether there are aluminum wires or bumps around the lithium battery cover, whether there are any crush marks on the lower plastic of the lithium battery cover, and whether there are any scratches on the terminals of the lithium battery cover.

[0057] The 3D contour detection device 13 can perform 3D contour scanning detection on the lithium battery cover plate, specifically to detect the flatness of the lithium battery cover plate, the flatness of the aluminum sheet on the lithium battery cover plate, and the height between the aluminum sheet on the lithium battery cover plate and the plane of the lithium battery cover plate body.

[0058] The material sorting mechanism 14 sorts the lithium battery cover plates that have completed all processes on the discharge conveyor belt 7 according to the detection structure of the back photograph detection device 6, the front photograph detection device 12 and the 3D contour detection device 13.

[0059] The entire process is fully automated, which greatly reduces or eliminates human intervention, thus saving labor costs and reducing the intensity of manual labor.

[0060] In this embodiment, both the back cleaning device 5 and the front cleaning device 11 include a first electric slide 17 and a plasma cleaner 18. Both the first electric slide 17 and the plasma cleaner 18 are existing technologies. The plasma cleaner 18 is connected to the horizontal drive end of the first electric slide 17, allowing the first electric slide 17 to drive the plasma cleaner 18 to move horizontally, thus increasing the cleaning coverage of the plasma cleaner 18. The plasma release end of the plasma cleaner 18 is surrounded by a hood 39 for dust collection. The hood 39 is connected to an external dust collection device via a pipe.

[0061] The first electric slide 17 in the back cleaning device 5 is horizontally mounted on the workbench 1. The plasma released by the plasma cleaner 18 in the back cleaning device 5 bombards the back of the lithium battery cover plate that is grabbed by the material transfer suction cup 1007 adjacent to the four-position rotary divider 2 when it is in a stopped state, so as to achieve the purpose of cleaning the back of the lithium battery cover plate.

[0062] The first electric slide 17 in the front cleaning device 11 is horizontally mounted on the workbench 1 and located above the feed conveyor belt 4. The plasma cleaner 18 in the front cleaning device 11 releases plasma to bombard the front of the lithium battery cover being conveyed on the feed conveyor belt 4, so as to achieve the purpose of cleaning the front of the lithium battery cover.

[0063] In this embodiment, both the rear-facing photo detection device 6 and the front-facing photo detection device 12 include a CCD detection camera 19, a CCD camera light source 20, and a reflector 21. The CCD detection camera 19 is mounted on the worktable 1 via an XY-direction fine-tuning component. The CCD camera light source 20 and the reflector 21 are located in front of the lens of the CCD detection camera 19. The CCD camera light source 20 is mounted above the worktable 1, and the reflector 21 is mounted above the worktable 1 via a Y-direction displacement fine-tuning component.

[0064] Specifically, when the four-station rotary divider 2 is in operation, the lithium battery cover plate gripped by the material transfer suction cup 1007 in the material transfer mechanism 10 passes between the CCD camera light source 20 and the reflector 21 in the back-side photographic detection device 6, with the reflector 21 positioned above the lithium battery cover plate it passes over. When the four-station rotary divider 2 is in a stopped state, the CCD detection camera 19 in the back-side photographic detection device 6 takes a photograph of the back of the lithium battery cover plate gripped by the adjacent material transfer suction cup 1007. The CCD camera light source 20 and the reflector 21 in the front-side photographic detection device 12 are located above and below the discharge conveyor belt 7, respectively, and the CCD detection camera 19 in the front-side photographic detection device 12 takes a photograph of the front of the lithium battery cover plate conveyed on the discharge conveyor belt 7.

[0065] The aforementioned XY-axis displacement fine-tuning assembly includes an X-axis displacement slide 22 and a first Y-axis displacement slide 23. A CCD detection camera 19 is mounted on the movable end of the X-axis displacement slide 22, which is positioned above the worktable 1. The aforementioned Y-axis displacement fine-tuning assembly includes a second Y-axis displacement slide 24, which is also mounted above the worktable, with a reflector 21 mounted on its movable end. The X-axis displacement slide 22, the first Y-axis displacement slide 23, and the second Y-axis displacement slide 24 are all existing technologies, employing long-stroke rack and pinion dovetail groove displacement platforms, which are readily available. Their specific structures do not require further explanation. The arrangement of the X-axis displacement slide 22, the first Y-axis displacement slide 23, and the second Y-axis displacement slide 24 facilitates the adjustment of the position of the CCD detection camera 19 and the reflector 21.

[0066] In this embodiment, the 3D contour detection device 13 includes a second electric slide 25 and a 3D scanner 26. Both the second electric slide 25 and the 3D scanner 26 are existing technologies. The second electric slide 25 is horizontally mounted on the worktable 1 and located above the discharge conveyor belt 7. The 3D scanner 26 is located at the moving end of the second electric slide 25. The second electric slide 25 can drive the 3D scanner to move horizontally, which can increase the scanning coverage of the 3D scanner. Specifically, the 3D scanner 26 is used to perform 3D contour scanning detection on the lithium battery cover plate conveyed on the discharge conveyor belt 7. Specifically, it is used to detect the flatness of the lithium battery cover plate, the flatness of the aluminum sheet on the lithium battery cover plate, and the height between the aluminum sheet on the lithium battery cover plate and the plane of the lithium battery cover plate body.

[0067] In this embodiment, the material sorting mechanism 14 includes a third electric slide 27, a cylinder 28, a vertical slide rail 29, a slider 30, a connecting plate 31, and a material sorting suction cup 32. The third electric slide 27 is horizontally mounted on the workbench 1 and located above the discharge conveyor belt 7. The cylinder 28 and the vertical slide rail 29 are both located at the moving end of the third electric slide 27. The linear drive direction of the cylinder 28 is parallel to the guide direction of the vertical slide rail 29. The connecting plate 31 is slidably connected to the vertical slide rail 29 through the slider 30. A limiting groove 33 is provided at the upper end of the connecting plate 31. A limiting slider 34 is provided in the limiting groove 33. The upper end face of the limiting slider 34 is connected to the piston end of the cylinder 28. A spring 35 is provided between the lower end face of the limiting slider 34 and the bottom of the limiting groove 33. The body of the spring 35 is located in the limiting groove 33. The upper and lower ends of the spring 35 are respectively connected to the lower end face of the limiting slider 34 and the bottom of the limiting groove 33. The material sorting suction cup 32 is located at the lower end of the connecting plate 31. The horizontal drive of the third electric slide 27 and the vertical drive of the cylinder 28 enable the material sorting suction cup 32 to move horizontally and vertically, so as to sort the material from the discharge conveyor belt 7 onto the good product conveyor belt 15 and the defective product conveyor belt 16.

[0068] In this embodiment, when the front cleaning device 11 blows the dust off the lithium battery cover, a vacuum cleaner 37 is provided on the workbench 1 below the feeding conveyor belt 4 in order to collect the dust. The vacuum cleaner 37 is located directly below the front cleaning device 11 and is a vacuum cover with a pipe connected to an external vacuuming device.
