[0002] In today's rapidly developing photovoltaic industry, increasing overall equipment capacity while reducing equipment size and production costs has been a constant challenge for photovoltaic cell production lines throughout their history. As new markets continue to demand larger cells, equipment size has gradually increased, driving up hardware costs and creating obstacles to reducing cell costs.

[0003] In the current mainstream CVD and PVD automatic loading and unloading equipment on the market, cell cells are removed from the basket by a cell-picking mechanism, placed on the cell conveyor line, and then transferred to the cell-picking position of the gantry gripper, where they wait for the gantry gripper to pick them up. During this waiting period, the cell-picking mechanism and cell conveyor line are unable to continue feeding cells, resulting in low utilization rates.

[0035] like Figures 1 to 10As shown, the utility model discloses a battery cell conveying and lifting mechanism, which includes a support platform 105, a lifting member 304, a conveyor line 100, a lifting mechanism 200 and a rotating mechanism 300.

[0036] Several support platforms 105 are provided on the conveyor line 100 for supporting battery cells. The lifting mechanism 200 is fixed on both sides of the frame 103 of the conveyor line 100, and the rotating mechanism 300 is rotatably provided on the lifting mechanism 200. Several lifting parts 304 are provided on the rotating mechanism 300. The lifting mechanism 200 can drive the rotating mechanism 300 and the lifting parts 304 to move up and down, so as to lift the battery cells on the support platform 105 off the support platform 105. The cell-picking mechanism and the conveyor line 100 can continue to feed cells. By utilizing the time for the gantry to pick up and place cells and replace the carrier, the cell feeding and caching on the lifting mechanism 200 and the conveyor line 100 are completed, so that two layers of battery cells can be cached on one conveyor line 100. The utilization rate of the cell-picking mechanism and the conveyor line 100 is improved. While meeting the production capacity requirements, the number of cell-picking mechanisms and the stepping conveyor line 100 is reduced, and the hardware cost and space occupancy are reduced.

[0037] Specifically, if Figure 2 As shown, the conveyor line 100 includes a conveyor power assembly 101, a conveyor belt 102, and a frame 103. The conveyor power assembly 101 is mounted on the frame 103, and the conveyor belt 102 is mounted on the conveyor power assembly 101. The conveyor belt 102 is driven to rotate by the conveyor power assembly 101. Support platforms 105 are evenly spaced on the conveyor belt 102.

[0038] Specifically, if Figure 5 、 Figure 6 As shown, the lifting mechanism 200 includes a lifting power assembly 201, a connecting rod assembly 202, a rocker assembly 203, a lifting guide rail assembly 204, and a lifting plate 205. The main body of the lifting power assembly 201 is fixed to the frame 103 of the conveyor line 100, and its movable end is connected to the connecting rod assembly 202. The connecting rod assembly 202 is movably hinged to the rocker assembly 203, and the rocker assembly 203 is movably hinged to the lifting plate 205. The lifting plate 205 is arranged on the frame 103 of the conveyor line 100 so as to be movable up and down via the lifting guide rail assembly 204. The rotating mechanism 300 is located on the lifting plate 205. The lifting power assembly 201 pushes the connecting rod assembly 202 forward, thereby driving the rocker assembly 203 to push the lifting plate 205 up and down on the lifting guide rail assembly 204, thereby achieving the up and down lifting of the lifting member 304.

[0039] The rocker assembly 203 comprises a rocker 2031, a fixed base 2032, and a follower bearing 2033. The fixed base 2032 is fixed to the frame 103 of the conveyor line 100. The rocker 2031 is L-shaped, with one end hinged to the connecting rod assembly 202, the other end hinged to the lifting plate 205 via the follower bearing 2033, and the center hinged to the fixed base 2032. When the connecting rod assembly 202 pushes the rocker 2031 forward, the rocker 2031 rotates around its center, tilting its other end, thereby driving the lifting plate 205 upward. Conversely, when the connecting rod assembly 202 pulls the rocker 2031 backward, the lifting plate 205 moves downward.

[0040] The lifting guide rail assembly 204 includes a slider and a slide rail that cooperate with each other. The slider is fixedly connected to the lifting plate 205, and the slide rail is fixedly connected to the frame 103 of the conveyor line 100. The slider and the slide rail enable the lifting plate 205 to move upward in a stable vertical direction.

[0041] The connecting rod assembly 202 includes a connecting rod and fisheye joints provided at both ends of the connecting rod. The fisheye joints are movably hinged to the rocker 2031 via a connecting shaft.

[0042] The lifting power assembly 201 is driven by a pneumatic cylinder, a screw drive, a screw drive, a belt drive, a rocker, an eccentric shaft, a hydraulic cylinder, an electric cylinder, or a linear motor. Because this disclosure is prior art known to those skilled in the art, the embodiments described are only partial, not complete, embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0043] Specifically, if Figure 5 、 Figure 7 As shown, the rotating mechanism 300 includes a rotating power assembly 301, a rotating support seat 302 and a rotating shaft 303. The main body of the rotating power assembly 301 and the rotating support seat 302 are respectively fixed on the lifting plate 205. One end of the rotating shaft 303 is connected to the movable end of the rotating power assembly 301, and the other end passes through the rotating support seat 302 and is rotatably arranged in the middle of the rotating support seat 302. The lifting members 304 are fixed on the rotating shaft 303 at equal intervals and correspond to the supported positions of the battery cells. By setting the rotating mechanism 300, the lifting members 304 are driven to flip, so that the lifting members 304 can avoid the first layer of battery cell group 104 during lifting and lowering, avoid affecting the transmission of battery cells by the conveyor line 100, better complete the battery cell feeding and caching on the conveyor line 100, and realize that one conveyor line 100 can cache two layers of battery cells.

[0044] Among them, a plurality of rotating shafts 303 can be provided according to the length of the conveyor line 100, and adjacent rotating shafts 303 are connected by couplings.

[0045] The rotary power assembly 301 is driven by a vane cylinder, a lead screw drive, a screw drive, a belt drive, a rocker, an eccentric shaft, a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a linear motor. Because this disclosure is prior art known to those skilled in the art, the embodiments described are only partial, not complete, embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0046] Specifically, if Figure 3 As shown, the lifting member 304 is in an inverted "L" shape, and the horizontal end in contact with the battery cell is in a wedge shape, so that it can be better inserted into the bottom of the battery cell and can also more stably support the battery cell.

[0047] Specifically, if Figure 3 、 Figure 4 As shown, four adjacent support platforms 105 correspond to the four corners of the battery cell; the support surface of the support platform 105 is in contact with two adjacent battery cells, and both sides of the support surface of the support platform 105 are provided with inclined surfaces. The inclined surfaces can make the battery cell more stable during the forward movement.

[0048] For ease of understanding, this utility model describes the functional principles of a single-group battery cell conveying and lifting mechanism as an example. However, given the differences in the internal spatial characteristics of different equipment, different combinations and required quantities of the conveyor line 100, lifting mechanism 200, and rotating mechanism 300 may differ from or be the same as those described in this utility model, and therefore should not be construed as limiting the scope of protection of this utility model.

[0049] First, the lifting member 304 is located below the first layer of battery cell group 104. Figure 8 As shown. The first layer of battery cell group 104 is transferred to the sheet-taking position of the gantry gripper through the power assembly of the conveyor line 100. The lifting mechanism 200 is lifted, driving the lifting member 304 to lift the battery cell off the support platform 105. After the battery cell is lifted, a space is formed between the lifting member 304 and the support platform 105. The first layer of battery cell group 104 continues to be transferred to the sheet-taking position of the gantry gripper through the power assembly of the conveyor line 100. The battery cell conveyor line 100 forms a two-layer battery cell cache of the first layer of battery cell group 104 and the second layer of battery cell group 106, as shown. Figure 9 After the gantry gripper has finished moving the second layer of battery cell group 106, the rotating mechanism 300 rotates to both sides, and the lifting member 304 opens to a certain angle, as shown in FIG. Figure 10 As shown, avoid the first layer of battery cell group 104. The lifting mechanism 200 drops to a safe position, the rotating mechanism 300 rotates inward, and the battery cell conveying and lifting mechanism returns to the Figure 8 Status shown.

[0050] In summary, the present invention can improve the utilization rate of the cell removal mechanism and the cell conveyor line, effectively reduce the space occupied by the equipment, and lower the equipment cost. At the same time, the structure is simple and compact, and easy to manufacture.

[0051] The present invention can be applied to loading and unloading equipment in the photovoltaic industry, including but not limited to CVD, PVD and other coating process sections. All improvements or changes in the equipment structure that can be completed by utilizing the operating mode of this mechanism should fall within the scope of protection of the claims attached to the present invention.

[0052] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner.
