Abstract
Description
[Technical Field]
[0001] This utility model belongs to the field of battery cell manufacturing technology, and in particular relates to a dual-station material box type automatic battery cell feeding device. [Background Technology]
[0002] During the production process of solar cells, the material box containing solar cells needs to be transported to the cell picking station by the material box feeding device. Then, the cell picking robot picks up the solar cells from the material box and loads them into the processing device.
[0003] Existing patent CN117361052A discloses a solar cell processing device, further disclosing a solar cell feeding device, which includes a feeding conveyor, a transition conveyor, and a cell-retrieving conveyor. The feeding conveyor includes two sets of feeding conveyor lines arranged side by side, each set comprising upper and lower layers. The upper layer inputs and supplies cells, while the lower layer outputs and recycles the cells. The transition conveyor receives a cell at the end of the feeding conveyor and moves horizontally to the cell-retrieving conveyor, conveying the cell to the cell-retrieving conveyor. The cell-retrieving conveyor is equipped with a cell transport function and a solar cell lifting function to achieve solar cell feeding. Empty cells return to the transition conveyor and descend to a lower position, then are output and recycled via the lower conveyor line of the feeding conveyor. In this feeding device, the transition conveyor is equipped with two sets of lifting and transferring conveyor mechanisms that combine horizontal transfer and lifting. Furthermore, the horizontal transfer distance of the transition conveyor is relatively large, resulting in high equipment cost and a large space occupation.
[0004] Therefore, it is necessary to provide a new dual-station cassette-type automatic cell feeding device to solve the above-mentioned technical problems. [Utility Model Content]
[0005] The main objective of this invention is to provide a dual-station, cassette-type automatic battery cell feeding device to solve the aforementioned technical problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a dual-station material box type automatic battery cell feeding device, which includes a first feeding line and a second feeding line arranged in parallel, a first feeding mechanism connected to the first feeding line, a second feeding mechanism arranged parallel and offset to the extension line of the second feeding line and located next to the first feeding mechanism, and a movable feeding line that moves horizontally between a first position and a second position; the movable feeding line connects to the second feeding line at the first position and connects to the second feeding mechanism at the second position.
[0007] Furthermore, the distance between the first feeding line and the second feeding line is less than the distance between the first feeding mechanism and the second feeding mechanism.
[0008] Furthermore, both the first feeding line and the second feeding line include a first upper conveyor line and a first lower conveyor line that are distributed in parallel.
[0009] Furthermore, the conveying length of the first feeding line is greater than that of the second feeding line; the conveying range of the first feeding line extends to the inlet and outlet of the first feeding mechanism; the combined conveying length of the second feeding line and the movable feeding line is consistent with the conveying length of the first feeding line.
[0010] Furthermore, the active feeding line includes a first cylinder, a first support driven by the first cylinder to move horizontally between the first position and the second position, a second upper conveyor line disposed on top of the first support, and a second lower conveyor line disposed on the first support and located below the second upper conveyor line.
[0011] Furthermore, both the upper conveyor line and the lower conveyor line are equipped with blocking mechanisms at their conveying ends.
[0012] Furthermore, both the first feeding mechanism and the second feeding mechanism include a first motor, a second support plate driven by the first motor to move up and down between a first height and a second height, a movable conveyor line disposed on the second support plate, and a lifting module fixed on the second support plate and located below the movable conveyor line.
[0013] Furthermore, the lifting module includes a second motor fixed on the second support plate and a lifting plate driven by the second motor to move up and down and extend into the battery cell box to lift the stacked battery cells upward as a whole.
[0014] Furthermore, the active conveyor line can carry N battery cell boxes at a time, and the lifting module is provided with N sets, corresponding to N battery cell boxes, where N is an integer and greater than or equal to 2.
[0015] Furthermore, the battery cell cassette is equipped with two independent hoppers, and each battery cell cassette is equipped with two sets of lifting modules, which correspond to the two independent hoppers respectively.
[0016] Compared with the prior art, the advantages of this utility model of a dual-station automatic battery cell feeding device with a cassette type are as follows: For dual-station feeding scenarios where the distance between the two feeding conveyor lines at the feeding end is small and the distance between the two feeding mechanisms at the feeding end is large, this solution directly connects one feeding line to one of the feeding mechanisms, and only sets up a horizontal transfer conveyor mechanism (i.e., a movable feeding line) between the other feeding line and the other feeding mechanism, eliminating the need for a set of horizontal transfer conveyors and reducing costs; a double-layer conveyor structure is set on the movable feeding line to achieve connection between the upper and lower conveyor lines; the feeding mechanism integrates lifting, conveying, and lifting functions for the battery cells inside the cassette. After feeding multiple sets of battery cell cassettes, the device lowers directly to a low position via lifting, then outputs all the cells at once, and returns to a high position to receive the next set of battery cell cassettes, resulting in a high cycle time and fast feeding efficiency.

Detailed Implementation Methods
[0026] Example 1:
[0027] Please refer to Figures 1-5 This embodiment is a dual-station cassette-type automatic battery cell feeding device 100, which includes a first feeding line 1 and a second feeding line 2 arranged in parallel, a first feeding mechanism 3 connected to the first feeding line 1, a second feeding mechanism 4 arranged parallel to and offset from the extension line of the second feeding line 2 and located next to the first feeding mechanism 3, and a movable feeding line 5 that moves horizontally between a first position and a second position; the movable feeding line 5 connects to the second feeding line 2 at the first position and connects to the second feeding mechanism 4 at the second position.
[0028] The distance between the first feeding line 1 and the second feeding line 2 is small to match the double-row material box conveyor line on the AGV feeding trolley. The first loading mechanism 3 and the second loading mechanism 4 constitute two feeding stations, and the distance between them is large to match the two sets of battery cell adsorption and handling mechanisms.
[0029] Since the distance between the first feeding line 1 and the second feeding line 2 is small, and the distance between the first feeding mechanism 3 and the second feeding mechanism 4 is large, in this embodiment, the first feeding line 1 and the first feeding mechanism 3 are set on the same straight line, and then the second feeding line 2 and the second feeding mechanism 4 are connected by a movable feeding line 5, thus eliminating the need for a set of movable feeding lines.
[0030] The first feeding line 1 and the second feeding line 2 have basically the same structure, and both include a first upper conveyor line 11 and a first lower conveyor line 12. The first upper conveyor line 11 is used to input full-load material boxes, and the first lower conveyor line 12 is used to output empty material boxes.
[0031] The conveying length of the first feeding line 1 is greater than that of the second feeding line 2. The conveying range of the first feeding line 1 extends to the inlet and outlet of the first feeding mechanism 3. The combined conveying length of the second feeding line 2 and the movable feeding line 5 is the same as that of the first feeding line 1.
[0032] The movable feeding line 5 includes a first cylinder 51, a first support 52 driven by the first cylinder 51 to move horizontally between the first position and the second position, a second upper conveyor line 53 disposed on top of the first support 52, and a second lower conveyor line 54 disposed on the first support 52 and located below the second upper conveyor line 53. To prevent debris from falling from the second upper conveyor line 53 onto the second lower conveyor line 54, a partition plate 55 is provided on the first support 52 between the second upper conveyor line 53 and the second lower conveyor line 54.
[0033] Both the upper conveyor line 53 and the lower conveyor line 54 are equipped with blocking mechanisms 56 at their conveying ends. The blocking mechanism 56 includes a second cylinder 561 and a blocking rod 562 that is driven by the second cylinder 561 to move up and down.
[0034] The first feeding mechanism 3 and the second feeding mechanism 4 have the same structure, and both include a first motor 31, a second support plate 32 driven by the first motor 31 to move up and down between a first height and a second height, a movable conveyor line 33 disposed on the second support plate 32, and a lifting module 34 fixed on the second support plate 32 and located below the movable conveyor line 33.
[0035] The first feeding mechanism 3 and the second feeding mechanism 4 are fixed on the second bracket 6. The first motor 31 is fixed on the second support plate 32, and its rotating end is provided with a drive gear (not shown in the figure). The second bracket 6 is provided with a vertically extending rack 311 that meshes with the drive gear.
[0036] The movable conveyor line 33 in the first feeding mechanism 3 is connected to the first upper conveyor line 11 in the first feeding line 1 at the first height position; and is connected to the first lower conveyor line 12 in the first feeding line 1 at the second height position.
[0037] The movable conveyor line 33 in the second feeding mechanism 4 is connected to the second upper conveyor line 53 in the movable feeding line 5 at the first height position; and is connected to the second lower conveyor line 54 in the movable feeding line 5 at the second height position.
[0038] The lifting module 34 includes a second motor 341 fixed on the second support plate 32 and a lifting plate 342 driven by the second motor 341 to move up and down and extend into the cell material box 200 to lift the stacked cells upward as a whole.
[0039] To improve feeding efficiency, the second upper conveyor line 53 and the second lower conveyor line 54 in the movable feeding line 5, as well as the movable conveyor line 33, can each carry N battery cell boxes 200 at a time. The lifting module 34 is configured with N sets, corresponding to N battery cell boxes 200, where N is an integer greater than or equal to 2. In this embodiment, N equals 3.
[0040] To ensure the stable position of multiple cell cassettes 200 on the movable conveyor line 33, a positioning module 35 is also provided on the second support plate 32 to position the multiple sets of cell cassettes 200 on the movable conveyor line 33. The positioning module 35 includes a positioning stop 351 located at the end of the movable conveyor line 33 and a clamping assembly 352 located at the beginning of the movable conveyor line 33. The clamping assembly 352 includes a third cylinder 3521 and a clamping block 3522 driven by the third cylinder 3521 to move parallel to the conveying direction of the movable conveyor line 33. The multiple cell cassettes 200 are arranged one after another on the movable conveyor line 33, and adjacent cell cassettes are limited by the cassette base plate.
[0041] In this embodiment, the cell cassette 200 is provided with two independent hoppers. Each cell cassette 200 is provided with two sets of lifting modules 34, and each lifting module 34 corresponds to one hopper. Each cell cassette 200 is provided with two sets of lifting modules 34, which independently lift the cell stacks in the two independent hoppers. Compared with one lifting module 34 lifting two stacks of cells, this can eliminate the inconsistency in lifting height caused by thickness errors between the two stacks of cells, and avoid the problems of incomplete adsorption or overpressure adsorption when adsorbing cells.
[0042] The workflow of the dual-station cassette-type automatic battery cell feeding device 100 in this embodiment is as follows: The first feeding line 1 and the second feeding line 2 input several fully loaded battery cell cassettes 200 via the first upper conveyor line 11. The battery cell cassettes 200 input via the first feeding line 1 are directly conveyed to the first feeding mechanism 3. The movable conveyor line 33 in the first feeding mechanism 3 receives three battery cell cassettes 200 at a first height position, and the positioning module 35 fixes them in place. The lifting module 34 lifts the battery cells in the three cassettes upwards, and the three cassettes are fed simultaneously. After all the battery cells are removed, the movable conveyor line 33 descends to a second height position, and the empty cassettes are conveyed to the first lower conveyor line 12 for recycling. The second feeding line 100... The battery cell cassettes 200 input from feed line 2 are fed onto the second upper conveyor line 53 in the movable feed line 5, and then move horizontally to the input end of the second feeding mechanism 4. After the movable conveyor line 33 in the second feeding mechanism 4 receives the three battery cell cassettes 200 at the first height position, the positioning module 35 fixes them, and the lifting module 34 lifts the battery cells in the three cassettes upwards. The three cassettes are fed simultaneously. After all the battery cells in the cassettes on the movable conveyor line 33 are removed, they descend to the second height position. The empty cassettes are conveyed to the second lower conveyor line 54 in the movable feed line 5, and then move to the first position to convey the empty cassettes to the first lower conveyor line 12 of the second feed line 2 for output and recycling.
[0043] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
