[0039] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Next, in conjunction with Figures 1-7 , a cleaning and full inspection device for a lithium battery cover plate disclosed in an embodiment of the present invention will be described in detail, including:

[0041] The workbench 1 is composed of a rectangular frame and a top plate laid on the top of the rectangular frame;

[0042] Four-station rotary divider 2, which is a prior art, with each rotation angle of 90°. The four-station rotary divider 2 is arranged on the workbench 1 through a support base 3. When the four-station rotary divider 2 is in a stopped state, four groups of workstations are successively provided with a feeding conveyor belt 4, a back cleaning device 5, a back photographing and detecting device 6, and a discharging conveyor belt 7 installed on the workbench 1 in the counterclockwise direction. Above the feeding conveyor belt 4, a front cleaning device 11 is arranged on the workbench 1. A material code scanner 38 is installed on the feeding conveyor belt 4, specifically for scanning the two-dimensional code on the lithium battery cover plate conveyed on the feeding conveyor belt 4. On the workbench 1, a front photographing and detecting device 12, a 3D contour detecting device 13, and a material sorting mechanism 14 are arranged adjacent to the discharging conveyor belt 7. A rotating disk 8 is concentrically arranged on the rotating end face of the four-station rotary divider 2. The rotating end of the four-station rotary divider 2 and the middle part of the rotating disk 8 both adopt a hollow design. A support column 9 is vertically arranged on the support base 3, and the support column 9 penetrates through the hollow parts in the rotating end of the four-station rotary divider 2 and the middle part of the rotating disk 8;

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

[0044] The disk 1000 is concentrically arranged at the top end of the support column 9. Special-shaped grooves vertically penetrating its body are formed on two edges of the disk 1000 adjacent to the feeding conveyor belt 4 and the discharging conveyor belt 7, and special-shaped sliders 1001 are embedded in the special-shaped grooves;

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

[0046] Four groups of rollers 1005 are respectively arranged on the top ends of the sliding plates 1003 in the four groups of vertical sliding components and are located on the upper end face of the disk 1000. The four groups of rollers 1005 roll on the upper end face of the disk 1000 when the four-station rotary divider 2 is in a working state. When the four-station rotary divider 2 is in a stopped state, any two adjacent groups of rollers 1005 are respectively located on the top surfaces of the special-shaped sliders 1001 in two special-shaped grooves on the disk 1000;

[0047] Two sets of lifting cylinders 1006 are both installed on the mounting seats provided on the body of the support column 5. The piston ends of the two sets of lifting cylinders 1006 are respectively connected to the bottom surfaces of the special-shaped sliders 1001 in two special-shaped grooves on the disc 1000. When the piston rods of the two sets of lifting cylinders 1006 extend, the top surfaces of the special-shaped sliders 1001 are flush with the top surface of the disc 1000.

[0048] Four sets of material shifting suction cups 1007 are respectively arranged at the bottoms of the sliding plates 1003 in the four sets of vertical sliding assemblies.

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

[0050] When the piston rods of the two sets of lifting cylinders 1006 are in the extended state, the top surfaces of the special-shaped sliders 1001 are flush with the top surface of the disc 1000. When two of the rollers 1005 are respectively located on the top surfaces of the special-shaped sliders 1001 in two special-shaped grooves on the disc 1000 when the four-station rotary indexing device 2 is in the stopped state, if the piston rods of the two sets of lifting cylinders 1006 retract, the heights of the two sets of special-shaped sliders 1001 decrease. At this time, the corresponding two sets of rollers 1005 quickly decrease in height under the action of the pulling force of the tension springs 1004, and the two sets of sliding plates 1003 corresponding to these two sets of rollers 1005 both drive the material shifting suction cups 1007 at the bottoms of their bodies to descend. The heights of the two sets of material shifting suction cups 1007 can be decreased to respectively cooperate with the transmission heights of the feeding conveyor belt 4 and the discharge conveyor belt 7, so as to facilitate taking materials from the feeding conveyor belt 4 and placing materials on the discharge conveyor belt 7 respectively.

[0051] The feeding conveyor belt 4 conveys the lithium battery covers. When the lithium battery covers are conveyed to the cleaning position covered by the front cleaning device 11, the feeding conveyor belt 4 stops running, and the front cleaning device 11 starts to clean the front surface of the lithium battery covers below it. After the cleaning is completed, 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 respectively located on the top surfaces of the special-shaped sliders 1001 in two special-shaped grooves on the disc 1000. At this time, the piston rods of the two sets of lifting cylinders 1006 are in the extended state, and the top surface of the special-shaped slider 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 downward and grabs the front-side cleaned lithium battery cover plate on the feeding conveyor belt 4. Then the piston rods of the two sets of lifting cylinders 1006 extend. At this time, the top surface of the special-shaped slider 1001 remains flush with the top surface of the disc 1000. The four-station rotary divider 2 rotates 90°. The material transfer suction cup 1007 holding the lithium battery cover plate moves to the cleaning range covered by the back-side cleaning device 5 for back-side cleaning. As the four-station rotary divider 2 rotates, another set of material transfer suction cups 1007 that rotate to be adjacent to the feeding conveyor belt 4 also repeat the above-mentioned material-grabbing action. After the back-side cleaning 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 cleaning is transferred by the material transfer suction cup 1007 to the photographing range covered by the back-side photographing and detecting device 6 for photographing and detecting. After the back-side photographing 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 photographing and detecting is then transported above the discharging conveyor belt 7. Then the piston rods of the two sets of lifting cylinders 1006 retract, and the material transfer suction cup 1007 moves downward with the lithium battery cover plate that has completed the back-side photographing and detecting and places the lithium battery cover plate on the discharging conveyor belt 7. As the working station rotary divider 2 rotates continuously, the components at its four working stations and the two sets of lifting cylinders 1006 cooperate correspondingly to achieve the continuity of the work. When the working station rotary divider 2 stops rotating, the material transfer suction cups 1007 at the four working stations are respectively taking materials from the feeding conveyor belt 4, grabbing the lithium battery cover plate for back-side cleaning, grabbing the lithium battery cover plate for back-side photographing and detecting, and placing the grabbed lithium battery cover plate on the discharging conveyor belt 7. When the working 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 working stations;

[0053] When the discharge conveyor belt 7 receives the lithium battery cover plate, and when the front camera inspection device 12 and the 3D contour inspection device inspect the lithium battery cover plate conveyed by the discharge conveyor belt 7 below them, the discharge conveyor belt 7 is in a stopped state. The lithium battery cover plate on the discharge conveyor belt 7 first passes through the photographing range covered by the front camera inspection device 12, and the front camera inspection device 12 takes a front photo of the conveyed lithium battery cover plate for inspection. Then the lithium battery cover plate is conveyed to the scanning inspection range covered by the 3D contour inspection device 13, and the 3D contour inspection device 13 performs a 3D contour scan inspection on the lithium battery cover plate. When the 3D contour inspection device 13 performs the 3D contour scan inspection, the front camera inspection device 12 also synchronously takes a front photo of the subsequent conveyed lithium battery cover plate for inspection. After the lithium battery cover plate on the discharge conveyor belt 7 has completed the front photo inspection and the 3D contour scan inspection, 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 inspection results of the back camera inspection device 6, the front camera inspection device 12, and the 3D contour inspection device 13. It transfers the lithium battery cover plates without quality problems to the good product conveyor belt 15, transfers the lithium battery cover plates with repairable quality problems to the defective product conveyor belt 16. For the lithium battery cover plates with irreparable quality problems, the material sorting mechanism 14 does not sort them, and they directly fall into the waste recycling bin 36 as waste products.

[0054] From the above description, it can be seen that the present application can perform automatic cleaning and quality inspection on the lithium battery cover plate as follows:

[0055] The back cleaning device 5 and the front cleaning device 11 can respectively clean the back and the front of the lithium battery cover plate;

[0056] Through the photographing inspection of the lithium battery cover plate by the front camera inspection device 12 and the back camera inspection device 6, it is to detect whether there are aluminum wires, bumps around the lithium battery cover plate, whether the lower plastic on the lithium battery cover plate is damaged by pressing, whether the pole posts on the lithium battery cover plate are scratched, etc.;

[0057] Through the 3D contour inspection device 13, a 3D contour scan inspection can be performed on the lithium battery cover plate, specifically for detecting the flatness of the lithium battery cover plate, the flatness of the light aluminum sheet on the lithium battery cover plate, and the height between the light aluminum sheet on the lithium battery cover plate and the plane of the lithium battery cover plate body;

[0058] Through the material sorting mechanism 14, according to the inspection results of the back camera inspection device 6, the front camera inspection device 12, and the 3D contour inspection device 13, the material sorting mechanism 14 sorts the lithium battery cover plates that have completed all processes on the discharge conveyor belt 7;

[0059] The whole process realizes full automation, greatly reducing or eliminating manual participation, saving a great deal of labor costs to a large extent, and at the same time 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 sliding table 17 and a plasma cleaner 18. The first electric sliding table 17 and the plasma cleaner 18 are both prior arts. The plasma cleaner 18 is connected to the horizontal driving end of the first electric sliding table 17.

A hood 39 for dust suction is provided on the outer periphery of the plasma release end of the ion cleaner 18. The hood 39 is connected to an external dust suction device through a pipeline. Among them:

[0061] The first electric sliding table 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 grabbed by the material transfer suction cup 1007 adjacent to it when the four-station rotary divider 2 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 sliding table 17 in the front cleaning device 5 is horizontally mounted on the workbench 1 and is located above the feeding conveyor belt 4. The plasma released by the plasma cleaner 18 in the front cleaning device 5 bombards the front of the lithium battery cover plate conveyed on the feeding conveyor belt 4, so as to achieve the purpose of cleaning the front of the lithium battery cover plate;

[0063] In this embodiment, both the back photographing and detecting device 6 and the front photographing and detecting device 12 include a CCD detecting camera 19, a CCD camera light source 20, and a reflector 21.

The CCD camera light source 20 is mounted above the workbench 1, and the reflector 21 is arranged above the workbench 1 through a Y-direction displacement fine-tuning component;

[0064] Specifically, when the four-station rotary divider 2 is in the working state, the lithium battery cover plate grasped by the material displacement suction cup 1007 in the material transfer mechanism 10 passes between the CCD camera light source 20 and the reflector 21 in the back surface photographing detection device 6. The reflector 21 is located above the passing lithium battery cover plate. When the four-station rotary divider 2 is in the stopped state, the CCD detection camera 19 in the back surface photographing detection device 6 takes a picture and detects the back surface of the lithium battery cover plate grasped by the adjacent material displacement suction cup 1007. In the front surface photographing detection device 12, the CCD camera light source 20 and the reflector 21 are respectively located above and below the discharge conveyor belt 7, and the CCD detection camera 19 in the front surface photographing detection device 12 takes a picture and detects the front surface of the lithium battery cover plate conveyed on the discharge conveyor belt 7.

[0065] The above-mentioned XY-direction displacement fine-tuning assembly includes an X-direction displacement slide 22 and a first Y-direction displacement slide 23. The CCD detection camera 19 is movably installed on the X-direction displacement slide 22, and is arranged at the moving end of the first Y-direction displacement slide 23.

Through the settings of the X-direction displacement slide 22, the first Y-direction displacement slide 23, and the second Y-direction displacement slide 24, it is convenient to adjust the positions 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. The second electric slide 25 and the 3D scanner 26 are both prior arts. The second electric slide 25 is horizontally mounted on the workbench 1 and is located above the discharge conveyor belt 7. The 3D scanner 26 is arranged 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 range of the 3D scanner. The 3D scanner 26 is specifically used to perform 3D contour scanning detection on the lithium battery cover plate conveyed on the discharge conveyor belt 7, specifically for detecting the flatness of the lithium battery cover plate, the flatness of the optical aluminum sheet on the lithium battery cover plate, and the height between the optical aluminum sheet on the lithium battery cover plate and the plane of the lithium battery cover plate body.
