Description

[0002] Soft-pack batteries have advantages such as high operating voltage, high energy density, long cycle life, and no memory effect, making them a preferred choice for power batteries. Soft-pack batteries typically have power tabs with adhesive. However, after the automated production line produces the tabs, they need to be transferred to a tab-cutting machine for adhesive cutting. After cutting, the power tabs need to be transferred to a CCD inspection machine for appearance quality inspection, and the finished tabs also need to be manually stacked and arranged on trays. This process requires multiple machines and manual handling, resulting in low production efficiency, high labor intensity, difficulty in guaranteeing production quality, and high labor costs.

[0024] The components of this embodiment will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 3As shown, the material conveying mechanism 2 includes a material transverse movement drive module 21, a material transverse movement support 22, a material lifting cylinder 23, and a material loading platform 24.

The material lifting cylinder 23 is installed on the material transverse movement support 22 and is connected to the material loading platform 24 for transmission, thereby driving the material loading platform 24 to move up and down.

[0026] When the tab with tab adhesive is placed on the incoming material loading platform 24, the incoming material transverse drive module 21 can drive the incoming material loading platform 24 and the tab to move to the rotary loading mechanism 3.

[0027] like Figure 4 As shown, the rotary feeding mechanism 3 includes a rotary feeding bracket 31, a feeding lifting cylinder 32, a feeding rotary cylinder 33, a feeding suction cup mounting plate 34, and a rotary feeding suction cup 35.

The feeding rotary cylinder 33 is connected to the rotary feeding suction cup 35 through the feeding suction cup mounting plate 34 and drives it to rotate.

[0028] When the material conveying mechanism 2 delivers the electrode ear, the rotating feeding suction cup 35 picks up the electrode ear and rotates it horizontally by 90 degrees under the drive of the feeding rotary cylinder 33, placing the electrode ear into the electrode ear positioning and correction mechanism 4.

[0029] like Figure 5 and Figure 6 As shown, the electrode positioning and correction mechanism 4 includes a positioning bracket 41, a positioning support block 42, a positioning and material transfer drive module 43, a positioning lifting cylinder 44, a positioning and material transfer suction head 45, a front positioning and correction cylinder 46, a front positioning and correction push block 47, a side positioning and correction cylinder 48, and a side positioning and correction push block 49. Two positioning support blocks 42 are provided and are arranged parallel to each other on the top of the positioning bracket 41. The positioning and material transfer drive module 43 is installed below the positioning bracket 41. The drive part of the positioning and material transfer drive module 43 is connected to the positioning lifting cylinder 44 and drives it to move laterally. The positioning lifting cylinder 44 and the positioning and material transfer... The suction head 45 is driven and moves up and down. The positioning and transferring suction head 45 moves between the two positioning support blocks 42 through the through hole at the top of the positioning bracket 41. The front positioning and correction cylinder 46 is installed at one end of the positioning support block 42. The front positioning and correction cylinder 46 is driven and connected to the front positioning and correction push block 47 and moves it along the length direction of the positioning support block 42. The side positioning and correction cylinders 48 are installed on both sides of the other end of the positioning support block 42. The two side positioning and correction cylinders 48 are driven and connected to their respective side positioning and correction push blocks 49 and move them in the width direction of the positioning support block 42.

[0030] When the rotating feeding mechanism 3 places the electrode tab on one side of the positioning support block 42, the front positioning correction cylinder 46 drives the front positioning correction push block 47 to move and correct the front position of the electrode tab. Then, the positioning transfer suction head 45 picks up the electrode tab and, driven by the positioning transfer drive module 43, moves the electrode tab to the other side of the positioning support block 42. Then, the two side positioning correction cylinders 48 drive the side positioning correction push block 49 to move and correct the position of both sides of the electrode tab to facilitate the subsequent electrode tab cutting operation, so that the electrode tab cutting mechanism 6 can cut the excess electrode tab adhesive more accurately.

[0031] like Figure 7 As shown, the first transfer manipulator mechanism 5 includes a first transfer bracket 51, a first transfer drive module 52, a first transfer lifting cylinder 53, a first lifting cylinder connecting block 54, a first transfer suction cup mounting plate 55, and a first transfer suction cup 56. The first transfer drive module 52 is mounted on the first transfer bracket 51. The drive part of the first transfer drive module 52 is connected to the first transfer lifting cylinder 53 through the first lifting cylinder connecting block 54 and drives it to move laterally. The first transfer lifting cylinder 53 is connected to the first transfer suction cup 56 through the first transfer suction cup mounting plate 55 and drives it to move up and down.

[0032] Once the electrode tab is positioned, the first transfer robot arm mechanism 5 can pick up the electrode tab located on the positioning support block 42 and move it to the electrode tab cutting adhesive mechanism 6. After the electrode tab cutting adhesive mechanism 6 finishes cutting the electrode tab adhesive, it picks up the electrode tab and moves it to the photographing and conveying mechanism 7.

[0033] like Figure 8 As shown, the tab-cutting mechanism 6 includes a tab-cutting support 61, a tab-cutting horizontal movement cylinder 62, a tab-cutting moving upright plate 63, a tab-cutting lifting cylinder 64, a tab-cutting upper punch 65, and a tab-cutting lower punch 66.

The two tab-cutting horizontal movement cylinders 62 are respectively connected to their corresponding tab-cutting moving upright plates 63 and drive them to move horizontally. The tab-cutting lifting cylinder 64 and the tab-cutting lower punch 66 are respectively installed on the tab-cutting moving upright plate 63. The tab-cutting lifting cylinder 64 is connected to the tab-cutting upper punch 65 and drives it to move up and down. The tab-cutting lower punch 66 is located below the tab-cutting upper punch 65.

[0034] When the tab is lifted and moved to the tab cutting mechanism 6, the tab cutting lifting cylinder 64 can drive the tab cutting upper punch 65 to move downward, and cooperate with the tab cutting lower punch 66 with slits to cut both ends of the tab and remove excess tab.

[0035] like Figure 9 , Figure 10 and Figure 11As shown, the photo conveying mechanism 7 includes a photo conveying bracket 71, a photo conveying support block 72, a photo conveying moving module 73, a photo conveying moving seat 74, a photo conveying lifting cylinder 75, and a photo conveying suction head 76.

The photo conveying lifting cylinder 75 is installed on the photo conveying moving seat 74 and is connected to the photo conveying suction head 76 and drives it to move up and down.

[0036] After the electrode tab is cut, the image conveying suction head 76 picks up the electrode tab and, driven by the image conveying moving module 73, moves the electrode tab to the first CCD image inspection mechanism 8.

[0037] After the first CCD imaging and inspection mechanism 8 completes the imaging and conveying suction head 76 continues to hold the tab. Driven by the imaging and conveying moving module 73, the tab is moved between the tab flipping mechanism 10 and the first defective product removal mechanism 9, so that the tab flipping mechanism 10 flips the tab or the first defective product removal mechanism 9 removes the tab that has been detected as a defective product.

[0038] After the electrode flipping mechanism 10 flips the electrode, the photo-taking and conveying suction head 76 continues to hold the electrode and, driven by the photo-taking and conveying moving module 73, moves the electrode to the second CCD photo-taking and inspection mechanism 11.

[0039] like Figure 9 As shown, the first CCD imaging inspection mechanism 8 includes a first CCD imaging bracket 81 and a first CCD camera 82, with the first CCD camera 82 mounted on the first CCD imaging bracket 81.

The first defective product removal lifting cylinder 92 is connected to the first defective product removal suction cup 94 through the first defective product removal suction cup mounting plate 93 and drives it to move up and down.

[0041] When the first CCD imaging and inspection mechanism 8 detects that the tab is defective, the first defective product removal suction cup 94 picks up the defective tab, and the defective tab is sucked away by the first defective product removal horizontal movement cylinder 91 and the first defective product removal lifting cylinder 92.

[0042] like Figure 14 As shown, the tab flipping mechanism 10 includes a flipping bracket 101, a flipping rotary cylinder 102, and a flipping clamp cylinder 103. The flipping rotary cylinder 102 is mounted on the flipping bracket 101, and the rotation drive part of the flipping rotary cylinder 102 is connected to the flipping clamp cylinder 103 and drives it to rotate.

[0043] After the first CCD imaging and inspection mechanism 8 completes the imaging and determines that the product is good, the imaging and conveying mechanism 7 transfers the electrode tab to the electrode tab flipping mechanism 10. The flipping clamp cylinder 103 clamps the electrode tab, and the flipping rotation cylinder 102 drives the electrode tab to rotate 180 degrees.

[0044] like Figure 9 As shown, the second CCD imaging detection mechanism 11 includes a second CCD imaging bracket 111 and a second CCD camera 112, with the second CCD camera 112 mounted on the second CCD imaging bracket 111.

[0045] After the electrode tab is flipped over, the photographing and conveying mechanism 7 continues to move the electrode tab to the second CCD photographing and inspection mechanism 11, where the second CCD camera 112 can take a photograph and inspect the other surface of the electrode tab.

The second transfer lifting cylinder 123 is connected to the second transfer suction cup 126 through the second transfer suction cup mounting plate 125 and drives it to move up and down.

[0047] After the second CCD imaging and inspection mechanism 11 completes the imaging and inspection, if the electrode tab is a good product, the second transfer suction cup 126 can pick up the electrode tab and move it to the transverse material box stacking mechanism 14 under the drive of the second transfer drive module 122 and the second transfer lifting cylinder 123. If the electrode tab is a defective product, the second transfer suction cup 126 can pick up the electrode tab and move it to the second defective product removal mechanism 13 under the drive of the second transfer drive module 122 and the second transfer lifting cylinder 123.

[0049] When the second transfer robot arm mechanism 12 moves the defective product tab to the second defective product removal platform 133, the second defective product removal cylinder 132 drives the tab on the second defective product removal platform 133 to be removed.

The stacking alignment push cylinder 144 is located on one side of the material box and is connected to the stacking alignment push head 145.

[0051] When the second transfer robot 12 moves several good electrode tabs into the material box 143 one by one, the electrode tabs are stacked from bottom to top. After a certain number are placed, the stacking alignment pusher cylinder 144 drives the stacking alignment pusher head 145 to push the electrode tabs to align them and correct their positions, so that the unloading and traying robot 15 can pick up a pile of electrode tabs at once.

[0052] Preferably, there can be two material boxes 143. The material box lateral movement drive module 141 can drive the material box switching. When one material box is full of tabs, the other empty material box is replaced.

The unloading and unloading rotating cylinder 152 is mounted on the Z axis of the XYZ axis moving drive module 151. The unloading and unloading rotating cylinder 152 is connected to the unloading and unloading clamping cylinder 153 and drives it to rotate.

[0054] When one of the material boxes of the transverse material box stacking mechanism 14 is full of electrode tabs, the unloading tray clamp cylinder 153 clamps the electrode tabs located in the material box. The XYZ axis movement drive module 151 drives the unloading tray clamp cylinder 153 to move above the receiving tray mechanism 16. The unloading tray rotation cylinder 152 drives the unloading tray clamp cylinder 153 to rotate 90 degrees, placing a stack of electrode tabs longitudinally into the corresponding receiving slot of the receiving tray mechanism 16.

[0055] like Figure 20 As shown, the receiving tray mechanism 16 includes a tray moving bracket 161, a tray moving cylinder 162, and a tray moving carrier 163. The tray moving cylinder 162 is mounted on the tray moving bracket 161 and is connected to the tray moving carrier 163 by transmission, driving it to move laterally. Preferably, the receiving tray mechanism 16 can be provided with two sets.

[0056] When the tray on the moving pallet 163 is full of material, the moving cylinder 162 moves the tray on the moving pallet 163 out.

[0057] In summary, the present invention has a reasonable structural design and can complete a series of automated operations, such as automatic feeding of electrode tabs, automatic positioning and correction before cutting, automatic cutting of electrode tab adhesive, double-sided appearance inspection, automatic flipping of electrode tabs, removal of defective products, automatic alignment and stacking of electrode tabs, and automatic receiving and tray placement. It operates stably and reliably, has a high degree of automation, improves production efficiency and product quality, reduces labor intensity and production costs, and can meet the requirements of large-scale production of enterprises.
