[0035] First embodiment

[0036] Reference Figure 1 and Figure 2 The first embodiment of the utility model discloses a double-sided visual inspection device for a tab, comprising a visual inspection mechanism 8, a material-retrieving platform 6, a first manipulator 1 and a first slide 2. Below the visual inspection mechanism 8 is a visual inspection area, and the visual inspection mechanism 8 and the material-retrieving platform 6 are spaced apart along a first direction. In this embodiment, the visual inspection mechanism 8 is a CCD inspection device.

[0037] The first slide 2 extends along the first direction, and the visual inspection area and the material-retrieving platform 6 are located in the sliding path of the first slide 2. The first manipulator 1 is installed on the first slide 2, so that the first manipulator 1 can move between the visual inspection mechanism 8 and the material-retrieving platform 6 with the slide. The first manipulator 1 includes a clamping assembly and a flipping assembly, the clamping assembly is used to clamp the pole lug 9, the clamping assembly is arranged on the flipping assembly, and the flipping assembly is used to rotate the clamping assembly to rotate the pole lug 9 on the clamping assembly. In this embodiment, the flipping assembly 12 is a rotary cylinder, the clamping assembly is a pneumatic finger, and the clamping assembly is installed on the output shaft of the flipping assembly 12.

[0038] In this embodiment, the tab 9 is placed on the material taking platform 6, and the first manipulator 1 is driven by the first slide 2 to approach the material taking platform 6, and the tab 9 is clamped by the clamping assembly and moved to the visual inspection area driven by the first slide 2, and the visual inspection mechanism 8 inspects the surface of the tab 9. After the inspection, the first manipulator 1 rotates, and the visual inspection mechanism 8 inspects the other side surface of the tab 9, so that both sides of the tab 9 are inspected. This ensures that both sides of the tab 9 meet the production standards, and further ensures that the quality of the battery using the tab 9 is guaranteed.

[0039] In this embodiment, the flipping component 12 is a common rotary cylinder, and the clamping component uses pneumatic fingers, which are also called pneumatic grippers or pneumatic gripping fingers. Both use gas as a drive, so they can share the same compressed gas source.

[0040] In this embodiment, the double-sided visual inspection device for the tab also includes a lifting assembly 4, a transfer platform 3 and a second slide 5. The upper surface of the transfer platform 3 is used to store the tab 9, the transfer platform 3 is fixed on the output end of the lifting assembly 4, the lifting assembly 4 is fixed on the second slide 5, and the second slide 5 extends along the first direction, so that the lifting assembly 4 and the transfer platform 3 enter and exit the visual inspection area with the second slide 5. The lifting assembly 4 is lower than the first manipulator 1, and the output end of the lifting assembly 4 is extended and retracted up and down to drive the transfer platform 3 to move up and down, so that the upper surface of the transfer platform 3 receives the tab 9 in the visual inspection area. The lifting assembly 4 in this embodiment is a cylinder, and the cylinder is extended and retracted up and down.

[0041] In this embodiment, the upper surface of the transfer platform 3 is used to store the pole lug 9. After the pole lug 9 completes the double-sided inspection, the transfer platform 3 moves to the visual inspection area to receive the inspected pole lug 9. The specific process is as follows: After the first manipulator 1 flips over, the pole lug 9 completes the second side surface inspection, and the transfer platform 3 enters the visual inspection area driven by the second slide 5. At this time, the transfer platform 3 is lower than the pole lug 9 clamped by the first manipulator 1. When the transfer platform 3 is directly below the pole lug 9, the jacking assembly 4 moves upward, driving the transfer platform 3 to contact the pole lug 9. At this time, the first manipulator 1 releases the pole lug 9, and the pole lug 9 is directly placed on the transfer platform 3. Finally, the pole lug 9 goes out of the visual inspection area with the transfer platform 3 to enter the next process.

[0042] Reference Figure 3In this embodiment, a plurality of vacuum suction cups 32 are provided on the upper surface of the transfer platform 3. More specifically, a plurality of receiving holes 31 are provided on the upper surface of the transfer platform 3, and the receiving holes 31 are arranged at intervals along the first direction. The number of the receiving holes 31 is greater than the number of the vacuum suction cups 32, and the vacuum suction cups 32 are installed in a part of the receiving holes 31. In this embodiment, the vacuum suction cups 32 are centrally installed in the receiving holes 31 close to the material taking platform 6. In other embodiments, when the size of the pole lug 9 is large, a plurality of vacuum suction cups 32 can be dispersedly installed in the receiving holes 31 close to the boundary of the transfer platform 3, so that the vacuum suction cups 32 can stably absorb the pole lug 9. Therefore, the number of the plurality of receiving holes 31 in this embodiment is greater than the number of the vacuum suction cups 32, and the effect is mainly to expand the scope of application of the transfer platform 3.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the double-sided visual inspection device for the pole tab also includes a third slide 7 and a second manipulator. The second manipulator is arranged on the third slide 7, and the third slide 7 moves between the detection mechanism and the next station to transport the pole tab 9 obtained by the second manipulator from the detection mechanism to the next station, wherein the second manipulator is a suction cup manipulator. The third slide 7 in this embodiment can be installed according to the position of the next station, and the second manipulator in this embodiment is a suction cup manipulator, or the grasping device of the manipulator is a suction cup, and the function of the second manipulator is to grab the pole tab 9 from the transfer platform 3. Therefore, the suction cup on the second manipulator is set downward to suck the pole tab 9 from the top of the transfer platform 3.

[0044] Reference Figure 4 In this embodiment, the upper surface of the material taking platform 6 is used to place the pole ear 9, and a plurality of air holes 61 are arranged in the material taking platform 6. The air inlet end of the air hole 61 is arranged on the upper surface of the material taking platform 6, and the air outlet end of the air hole 61 is connected to the vacuum device. The function of the air hole 61 is similar to that of the vacuum suction cup 32, and will not be described in detail.

[0045] In this embodiment, the material retrieving platform 6 is provided with a first storage station and a second storage station, the first storage station and the second storage station are arranged along the first direction, and the first storage station is located on the side of the second storage station close to the visual inspection area. In this embodiment, two tabs 9 can be placed on the material retrieving platform 6 at a time.

[0046] To this end, the first slide 2 slides between a first preset position, a second preset position and a visual inspection area. The first preset position, the second preset position and the visual inspection area are arranged side by side along a straight line. The first preset position and the visual inspection area are close to both ends of the sliding path of the first slide 2, and the second preset position is located between the first preset position and the inspection station.

[0047] When the slide moves to the second preset position, the manipulator clamps the pole lug 9 on the first storage station;

[0048] When the slide moves to the first preset position, the robot grips the pole lug 9 on the second storage station.

[0049] Second embodiment

[0050] The difference between this embodiment and the first embodiment is that: in this embodiment, only one storage station is provided on the material retrieving platform, and the first slide 2 slides between the visual inspection area and the material retrieving platform.
