Description

Technical Field

[0001] This invention relates to the field of pouch battery manufacturing technology, and in particular to an integrated device for IV testing of battery cells and tab cutting of excess adhesive. Background Technology

[0002] After packaging, soft-pack lithium batteries require the removal of excess adhesive and electrical function testing at one end of the cell tabs. Existing equipment uses a linear transport module to sequentially transfer cells from the conveyor belt to the excess adhesive removal and testing mechanisms. The processed cells are then returned to the conveyor belt. This existing structure suffers from long transport distances, low functional integration, and low production efficiency. To integrate the excess adhesive removal and electrical function testing, a turntable structure can be used to sequentially transport the cells to each station. However, this presents a problem: when cells are placed on the turntable via the linear transport module, the tab direction is parallel to the tangent of the turntable's rotation direction, hindering the removal of excess adhesive and tab testing. The cells need to be rotated 90° so that the tabs face outwards from the turntable for proper removal of excess adhesive and electrical function testing. Therefore, it is necessary to develop an integrated IV testing and excess adhesive removal device for the cells to solve these problems. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 11As shown, an integrated device for IV testing and tab cutting of battery cells includes a frame 01, a rotary drive mechanism 02, a rotary worktable 03, a battery cell rotating platform 04, a platform drive mechanism 05, a platform locking mechanism 06, a locking release mechanism 07, a battery cell clamping mechanism 08, a clamping release mechanism 09, a first tab cutting mechanism 10, a testing mechanism 11, a second tab cutting mechanism 12, a first CCD positioning mechanism 13, and a second CCD positioning mechanism 14. The rotary drive mechanism 02 is fixed above the frame 01, and the rotary worktable 03 is fixed at the power output end of the rotary drive mechanism 02. Multiple sets of the battery cell rotating platform 04 are arranged on the outer periphery of the rotary worktable 03. The battery cell rotating platform 04 includes a mounting flange 041, a rotating... The rotating shaft 042, positioning block 043, adsorption platform 044, and first connecting block 045 are fixed to the rotary worktable 03 via mounting flange 041. The rotating shaft 042 is slidably connected to the mounting flange 041 and can rotate on the mounting flange 041. The positioning block 043 and adsorption platform 044 are sequentially fixed to the upper end of the rotating shaft 042. The lower end face of the positioning block 043 contacts the mounting flange 041. The first connecting block 045 is fixed to the lower end of the rotating shaft 042 and corresponds to the lower part of the rotary worktable 03. Positioning holes 0451 are provided at both ends of the first connecting block 045. The rotary worktable 03 is provided with a loading station. The platform drive mechanism 05, locking release mechanism 07, and clamping release mechanism 09 all correspond to the loading station. The first overflow cutting mechanism 10, the testing mechanism 11, and the second overflow cutting mechanism 12 are sequentially arranged on the outer periphery of the rotary table 03 along the downstream conveyor of the loading station. The first CCD positioning mechanism 13 and the second CCD positioning mechanism 14 are both fixed on the frame 01 and respectively mounted above the first overflow cutting mechanism 10 and the second overflow cutting mechanism 12. The platform drive mechanism 05 includes a first mounting frame 051, a first Z-axis cylinder 052, a first lifting frame 053, a rotary cylinder 054, and a second connecting block 055. The first mounting frame 051 is fixed on the frame 01, the first Z-axis cylinder 052 is fixed on the first mounting frame 051, and the lower end of the first lifting frame 053 is fixed to the power output end of the first Z-axis cylinder 052 and connected to it. The first mounting bracket 051 is slidably connected. The rotary cylinder 054 is fixed at the upper end of the first lifting frame 053. The second connecting block 055 is fixed at the power output end of the rotary cylinder 054. The upper end of the second connecting block 055 is provided with a positioning post 0551 corresponding to the positioning hole 0451. The platform locking mechanism 06 is fixed on the rotary worktable 03 and is used to lock the positioning block 043. The locking release mechanism 07 is fixed on the frame 01 and corresponds to the lower part of the platform locking mechanism 06. It is used to release the locking state of the positioning block 043. The battery cell pressing mechanism 08 is fixed on the rotary worktable 03 and is used to press the battery cell. The pressing release mechanism 09 is fixed on the frame 01 and corresponds to the lower part of the battery cell pressing mechanism 08. It is used to release the pressing state of the battery cell.

[0029] The rotary drive mechanism 02 drives the rotary worktable 03 to rotate, sequentially conveying the battery cells on the battery cell rotating platform 04 to each workstation. At the loading station, the battery cell clamping mechanism 08 is in the open state. The linear transport module places the battery cells on the conveyor belt onto the adsorption platform 044, which adsorbs and fixes the bottom of the battery cells. At this time, the battery cell tabs face the tangent direction of the rotation path of the rotary worktable 03. Then, the locking release mechanism 07 drives the platform locking mechanism 06 to release the locking state of the positioning block 043, allowing the positioning block 043 to rotate freely. Next, the first Z-axis cylinder 052 drives the first lifting frame 053 to rise, causing the positioning pin 0551 of the second connecting block 055 to insert into the positioning hole 0451 of the first connecting block 045. The first lifting frame 053 continues to rise to the highest position, causing the rotating shaft 042 to slide upward within the mounting flange 041, and the positioning block 043 to move away from the upper end of the mounting flange 041. Next, the rotary cylinder 054 drives the second connecting block 055 to rotate, thereby driving the adsorption platform 044 to rotate synchronously through the first connecting block 045, so that the electrode tabs of the battery cell face the outside of the rotary worktable 03. Subsequently, the platform driving mechanism 05, the locking release mechanism 07, and the pressing release mechanism 09 are reset in sequence, so that the platform locking mechanism 06 relocks the positioning block 043, and the battery cell pressing mechanism 08 presses the battery cell down. The rotary worktable 03 transports the battery cells to the subsequent workstations in sequence. When the battery cell completes all processes and returns to the loading station, the pressing release mechanism 09 drives the battery cell pressing mechanism 08 to open, and the locking release mechanism 07 drives the platform locking mechanism 06 to release the locking state. The platform driving mechanism 05 rotates the battery cells on the battery cell rotating platform 04 to be in the same direction as the conveyor belt in the same way. The linear transport module transports the processed battery cells back to the conveyor belt and places the next set of battery cells on the adsorption platform 044, and so on. Although this design uses a 90° rotation of the battery cell as an example, if the battery cell tabs are radially inward along the rotary table 03 after loading, the rotation angle can be set to 180° to achieve the same goal of the tabs facing outward. The advantage of this design is that, through the cooperation of the stage drive mechanism 05 and the battery cell rotating stage 04, the battery cell can rotate at a certain angle on the rotary table 03, thus causing the battery cell tabs to face outward from the rotary table 03. This facilitates subsequent processing or inspection of the tabs at subsequent workstations, and also allows for the integrated layout of multiple workstations, saving manufacturing costs and space, while simultaneously improving production efficiency.

[0030] The platform locking mechanism 06 includes a transverse slide 061, a fixed base 062, a sliding base 063, and a first elastic telescopic member 064. The transverse slide 061 is fixed above the rotary worktable 03, the fixed base 062 is fixed on the transverse slide 061, and the sliding base 063 is slidably connected to the transverse slide 061. The two ends of the first elastic telescopic member 064 are respectively fixed on the fixed base 062 and the sliding base 063. A positioning boss 0631 is provided on the side of the sliding base 063 away from the first elastic telescopic member 064. V-shaped positioning grooves 0431 are provided around the positioning block 043. The shape of the positioning boss 0631 matches the V-shaped positioning grooves 0431 and is inserted into one of the V-shaped positioning grooves 0431.

[0031] In the locked state, the first elastic telescopic member 064 drives the sliding seat 063 to press against the positioning block 043, and the positioning boss 0631 is inserted into the V-shaped positioning groove 0431, so that the positioning block 043 is fixed firmly at a precise angle. In the unlocked state, the locking release mechanism 07 drives the sliding seat 063 to move closer to the fixed seat 062, so that the first elastic telescopic member 064 is compressed, and the positioning boss 0631 is disengaged from the V-shaped positioning groove 0431, so that the positioning block 043 can rotate freely.

[0032] The locking release mechanism 07 includes a second Z-axis cylinder 071, a second lifting frame 072, and a drive roller 073. The second Z-axis cylinder 071 is fixed on the frame 01 with its power output end facing upward. The second lifting frame 072 is fixed to the power output end of the second Z-axis cylinder 071. The drive roller 073 is rotatably mounted on the second lifting frame 072. The platform locking mechanism 06 also includes a linkage block 065, which is fixed on the sliding seat 063. The lower end of the linkage block 065 passes through the rotary worktable 03 and has a driving inclined surface 0651 at its bottom. The driving inclined surface 0651 corresponds to the top of the drive roller 073.

[0033] When the locking state of the positioning block 043 needs to be contacted, the second Z-axis cylinder 071 drives the second lifting frame 072 and the driving roller 073 to rise. The driving roller 073 contacts the driving inclined surface 0651 and drives the linkage block 065 to move towards the fixed seat 062, thereby driving the sliding seat 063 to move, and finally causing the positioning boss 0631 to disengage from the V-shaped positioning groove 0431.

[0034] The sliding seat 063, the first elastic telescopic member 064 and the linkage block 065 are all provided in two sets and symmetrically arranged on both sides of the fixed seat 062. The drive roller 073 is provided in two sets on the second lifting frame 072 and corresponds to the two sets of linkage blocks 065 respectively.

[0035] The locking release mechanism 07 can simultaneously drive the two sets of sliding seats 063 to move, thereby simultaneously unlocking the two sets of battery cells. In other words, the linear transport module can simultaneously load and unload the two sets of battery cells, improving production efficiency.

[0036] The cell clamping mechanism 08 includes a second mounting frame 081, a fixed top plate 082, a third lifting frame 083, a movable pressure plate 084, and a second elastic telescopic member 085. The second mounting frame 081 is fixed on the rotary worktable 03, the fixed top plate 082 is fixed on the upper end of the second mounting frame 081, the third lifting frame 083 is slidably connected to the second mounting frame 081, the movable pressure plate 084 is fixed on the third lifting frame 083 and corresponds to the upper part of the adsorption platform 044, and the upper and lower ends of the second elastic telescopic member 085 are respectively fixed on the fixed top plate 082 and the movable pressure plate 084.

[0037] In the compressed state, the second elastic telescopic member 085 drives the movable pressure plate 084 to press the battery cell onto the adsorption platform 044. When it is necessary to release the compressed state, the compression release mechanism 09 drives the third lifting frame 083 to slide upward on the second mounting frame 081, thereby driving the movable pressure plate 084 to rise and no longer press the battery cell.

[0038] The clamping release mechanism 09 includes a third mounting bracket 091, a third Z-axis cylinder 092, a guide sleeve 093, and a lifting column 094. The third mounting bracket 091 is fixed below the frame 01. The third Z-axis cylinder 092 is fixed on the third mounting bracket 091 with its power output end facing upward. The guide sleeve 093 is fixed on the frame 01. The lower end of the lifting column 094 is fixed to the power output end of the third Z-axis cylinder 092. The lifting column 094 is slidably connected to the guide sleeve 093, and its upper end corresponds to the lower end of the third lifting frame 083. The lower end of the third lifting frame 083 passes through the rotary worktable 03.

[0039] When it is necessary to release the clamping state, the third Z-axis cylinder 092 drives the lifting column 094 to slide upward in the guide sleeve 093. The upper end of the lifting column 094 drives the lower end of the third lifting frame 083 to move upward, thereby driving the movable pressure plate 084 to rise and no longer clamp the battery cell.

[0040] The first overflow cutting mechanism 10 includes an X-axis drive motor 101, a Y-axis drive motor 102, a rotary drive motor 103, a fourth mounting bracket 104, a fourth Z-axis cylinder 105, an upper cutter 106, a fifth Z-axis cylinder 107, a connecting seat 108, a lower cutter 109, and a collection pipe 1010. The X-axis drive motor 101 is fixed to the frame 01, the Y-axis drive motor 102 is fixed to the power output end of the X-axis drive motor 101, the rotary drive motor 103 is fixed to the power output end of the Y-axis drive motor 102, and the fourth mounting bracket 104 is fixed to the power output end of the rotary drive motor 103. The fourth Z-axis cylinder 105 and the fifth Z-axis cylinder 107 are respectively fixed on the upper and lower sides of the fourth mounting bracket 104. The upper cutter 106 is fixed on the power output end of the fourth Z-axis cylinder 105. The connecting seat 108 is fixed on the power output end of the fifth Z-axis cylinder 107. The lower cutter 109 is fixed on the connecting seat 108 and corresponds to the lower part of the upper cutter 106. Both the upper cutter 106 and the lower cutter 109 correspond to one side of the rotary worktable 03. The connecting seat 108 is vertically provided with a material drop hole. The upper end of the material drop hole corresponds to the side of the lower cutter 109. The collecting pipe 1010 is fixed below the connecting seat 108 and communicates with the material drop hole.

[0041] When the battery cell reaches below the first CCD positioning mechanism 13, the camera on the first CCD positioning mechanism 13 takes a picture of the battery cell's tabs to determine their precise position. Then, the X-axis drive motor 101 and the Y-axis drive motor 102 move according to the tab position data, while the rotation drive motor 103 adjusts the angle of the fourth mounting bracket 104, so that the upper cutter 106 and the lower cutter 109 are precisely aligned with the position where excess glue needs to be cut. Next, the fourth Z-axis cylinder 105 and the fifth Z-axis cylinder 107 drive the upper cutter 106 and the lower cutter 109 to approach the excess glue position and cut off the excess glue. The fallen excess glue passes through the drop hole and the collection pipe 1010 and reaches the collection container for collection. The first excess glue cutting mechanism 10 is responsible for cutting off the excess glue on one side of the battery cell. Similarly, the second CCD positioning mechanism 14 takes a picture of the tab position, and the second excess glue cutting mechanism 12 is responsible for cutting off the excess glue on the other side of the battery cell.

[0042] The fourth Z-axis cylinder 105, the upper cutter 106, the fifth Z-axis cylinder 107, the connecting seat 108, the lower cutter 109, and the collection pipe 1010 are arranged in two sets side by side on the fourth mounting frame 104. The structure of the second overflow cutting mechanism 12 is the same as that of the first overflow cutting mechanism 10.

[0043] That is, the first overflow cutting mechanism 10 can simultaneously cut the overflow of two sets of battery cells. It can be set up so that the first overflow cutting mechanism 10 cuts the overflow of the two sets of battery cells at the outer end, while the second overflow cutting mechanism 12 cuts the overflow of the two sets of battery cells at the inner end (the end of the two battery cells that are close to each other). In this way, in the second CCD positioning mechanism 14, only one camera is used to simultaneously position the inner end of the two sets of battery cells, saving equipment costs.

[0044] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
