Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] like Figures 1-5 As shown, embodiments of the present invention include:
[0022] An automatic assembly equipment for honeycomb battery packs includes a loading and unloading mechanism 2, a unloading and loading mechanism 3, a cell tray 4, a assembly mechanism 5, and a grouping fixture 6, all mounted on a machine base 1. The assembly mechanism 5 consists of a cell bed 51 and a left cell stack 52 and a right cell stack 53. The left cell stack 52 and the right cell stack 53 are arranged on both sides of the cell bed 51 and alternately docked with each other. The loading and loading mechanism 2 docks the cell tray 4 with the left cell stack 52 and the right cell stack 53 respectively, and the unloading and loading mechanism 3 docks the cell bed 51 with the grouping fixture 6.
[0023] The left core stack 52 and the right core stack 53 each have a top 54 and a bottom 55. The bottom 55 is externally connected to a displacement mechanism 56 for docking with the feeding and conveying mechanism 2. The top 54 is provided with a distribution mechanism 57 for connecting to the core bed 51. The core bed 51 is provided with a linear module 58. The linear module 58, together with the distribution mechanism 57, enables the core bed 51 to alternately connect to the left core stack 52 and the right core stack 53 during the translation process.
[0024] Furthermore, the surface of the assembly tooling 6 is provided with several honeycomb-shaped brackets to accommodate material cavities 61.
[0025] Furthermore, the surface of the core bed 51 is provided with several parallel arc-shaped cell receiving grooves 511 with both ends penetrating the core bed 51.
[0026] Furthermore, the left core stack 52 and the right core stack 53 have the same structure, both consisting of a stack 521, a retaining wall 522, an exit point 523, and a cell contouring lifting seat 524. The stack 521 is surrounded by a retaining wall 522 along its path. The bottom of the stack 55 has an opening on the outer side of the exit path to the retaining wall 522 for the displacement mechanism 56 to dock. The bottom surface of the top of the stack 54 has an exit point 523. The exit point 523 is matched with a cell contouring lifting seat 524 that floats up and down. The cell contouring lifting seat 524 docks with the core bed 51 at the appropriate height.
[0027] Furthermore, a rodless cylinder 525 is provided along the path of the stack 521, and a stacking lever 526 is mounted on the rodless cylinder 525. The stacking lever 526 is placed inside the stack 521.
[0028] Furthermore, the stack 521 is provided with an ascending ramp 527 in the direction of the reverse exit 523.
[0029] Furthermore, the sorting mechanism 57 consists of a horizontal telescopic cylinder and a cell pusher plate 572 disposed at the head of the horizontal telescopic cylinder.
[0030] Furthermore, the displacement mechanism 56 comprises a bearing bracket 561, a receiving box 562, a gear 563, a rack 564, a cell end face support base plate 565, a discharge cylinder 566, and an adapter arm. The receiving box 562 is horizontally mounted on the bearing bracket 561, and the gear 563 is externally connected to the shaft end of the receiving box 562. The gear 563 meshes with a pneumatically lifting rack 564 to drive the receiving box 562 to rotate 90 degrees to either the left core stack 52 or the right core stack 53. The bottom of the receiving box 562 is provided with a cell end face support base plate 565. A discharge cylinder 566 is attached to the outside of the receiving box 562. The discharge cylinder 566 is vertically supported on the bottom of the cell end face support base plate 565 by a connecting arm. During the rotation process, the discharge cylinder 566 is connected to the left core stack 52 or the right core stack 53.
[0031] The battery cell tray 4 of this equipment contains neatly arranged cylindrical battery cells, with all cylindrical cells having the same positive and negative polarity. During the feeding process, a group of battery cells is transported to the receiving box 562 by the feeding and conveying mechanism 2. The bottom of the receiving box 562 is hollowed out and has a battery cell end face support plate 565. The feeding and conveying mechanism 2 vertically places the cylindrical battery cells into the receiving box 562. The receiving box 562 first undergoes a controlled flipping and repositioning action. Figure 3The receiving boxes 562 on both sides of the core bed 51 are rotated 90 degrees towards the axis of symmetry, so that the cylindrical cells lie flat with their end faces facing the left core stack 52 and the right core stack 53. Since the receiving boxes 562 are rotated symmetrically, all cylindrical cells are symmetrical with the same polarity. After the displacement and rotation are completed, the rodless cylinder 525 drives the stacking lever 526 to arrange the cylindrical cells into a stack. The cylindrical cells at the top of the stack flow into the cell contour lifting seat 524 through the stack outlet 523. When the cylindrical cells are lifted to the same height as the core bed 51, the sorting mechanism 57 pushes the cylindrical cells onto the core bed 51. According to the preset positive and negative polarity arrangement of the honeycomb bracket, the two sorting mechanisms 57 operate alternately, pushing the cells into the core bed 51 as needed. Since all the cylindrical cells are symmetrical about the same pole about the core bed 51, the electrodes of the cells from the left side of the core bed 51 and the electrodes of the cells from the right side of the core bed 51 are opposite to each other, thus obtaining a cell array with a specified sequence. After the array is completed, it is removed by the unloading and conveying mechanism 3, and the cells, after attitude adjustment, are directly inserted into the honeycomb cell bracket to complete one assembly process.
[0032] In summary, the present invention provides an automatic cell stack assembly device for honeycomb battery packs. A left-side cell stack 52 and a right-side cell stack 53 are constructed in parallel on both sides of the cell bed 51. A sorting mechanism 57 is used to make the cells at the top of the stack form an orderly positive and negative array on the cell bed 51 by alternately popping them out of the stack. This allows the cells to be accurately assembled into the honeycomb cell support, replacing manual operation and effectively improving yield and output.
