DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0032] like Figures 1 to 6 As shown, the feeding device 100 provided by the present invention is used for the transmission of half-cell battery cells. The battery cells described herein are all half-cell battery cells unless otherwise specified.

[0033] The feeding device 100 includes a transmission area 101 and a loading area 102 located downstream of the transmission area 101. The battery cells are transmitted from the transmission area 101 to the loading area 102. The battery cells are arranged in the loading area 102 according to a preset spacing and wait for the handling device to carry out the loading.

[0034] The transmission area 101 includes a first transmission member 101 a for transmitting battery cells. The battery cells are transmitted to the loading area 102 via the first transmission member 101 a.

[0035] The transmission area 101 further includes a third transmission member 101b for transmitting the battery cell from the first transmission member 101a to the loading area 102. The third transmission member 101b is provided with a correction member 101b-1 for correcting the position of the battery cell.

[0036] The correction member 101b-1 includes two groups of correction wheels respectively located on both sides of the third transmission member 101b, and the two groups of correction wheels can move toward each other or in opposite directions. Under normal conditions, the two groups of correction wheels maintain the maximum spacing, and the battery cells can be transferred between the two groups of correction wheels. When the battery cells are transferred between the two groups of correction wheels, the two groups of correction wheels move toward each other, that is, they move toward the battery cells at the same time. If the battery cells are deviated or tilted, one of the groups of correction wheels will first contact the battery cells and push the battery cells toward the other group of correction wheels until the spacing between the two groups of correction wheels and the length of the battery cells are consistent, and the two groups of correction wheels stop moving, completing the correction of the battery cells. The setting of the correction member 101b-1 can make the battery cells remain centered on the third transmission member 101b, and be transferred to the loading area 102 in this state.

[0037] The first transmission member 101a and the third transmission member 101b may be provided as one body or separately.

[0038] The loading area 102 includes a plurality of groups of loading positions 102a arranged along the transmission direction of the battery cells. Any group of the loading positions 102a includes two second transmission members 102b which are separately arranged. The two second transmission members 102b are respectively used to place two half-cell battery cells.

[0039] The half-cell battery is cut from a whole cell, and the whole cell can be cut into two half-cell batteries of the same size. That is, one group of the loading positions 102a is placed with two cut half-cell batteries, and each of the second transmission members 102b is placed with one half-cell battery.

[0040] The two second transmission members 102b are separately arranged, that is, the two second transmission members 102b are independent of each other, and each second transmission member 102b can be independently controlled to switch the working state. The second transmission member 102b is used to adjust the spacing between the half-cell battery cells while transmitting the half-cell battery cells, so that the half-cell battery cells are arranged according to the preset spacing.

[0041] The distance between two second transmission members 102b in any group of the material loading positions 102a is the same, and the distance between two second transmission members 102b in the same group of the material loading positions 102a is less than or equal to the distance between two adjacent second transmission members 102b in different groups of the material loading positions 102a.

[0042] Specifically, refer to Figure 3 This article takes two groups of the loading positions 102a and four separately arranged second transmission members 102b as an example for explanation.

[0043] Along the transmission direction of the battery cell, the four second transmission members 102b are respectively the second transmission member 1, the second transmission member 2, the second transmission member 3, and the third transmission member 4. The second transmission member 1 and the second transmission member 2 are located in the same group of the loading positions 102a, and the second transmission member 3 and the third transmission member 4 are located in the same group of the loading positions 102a. The four second transmission members 102b are completely the same.

[0044] The spacing between the center line of the second transmission member 1 along the cell transmission direction and the center line of the second transmission member 2 along the cell transmission direction is L1. The spacing between the center line of the second transmission member 3 along the cell transmission direction and the center line of the second transmission member 4 along the cell transmission direction is also L1. The spacing between the center line of the second transmission member 2 along the cell transmission direction and the center line of the second transmission member 3 along the cell transmission direction is L2, and L2≥L1.

[0045] The second transmission member 102b includes a support member 102b-1 and transmission belts 102b-2 located on both sides of the support frame 102b-1 along a direction perpendicular to the transmission direction of the battery cells. The distance between the two transmission belts 102b-2 is less than or equal to the first preset distance.

[0046] The first preset spacing can be specifically determined according to the length of the battery cell transmitted by the feeding device. The first preset spacing is smaller than the length of the transmitted battery cell, that is, the spacing between the two conveyor belts 102b-2 is smaller than the length of the transmitted battery cell, so that both ends of the battery cell along the length direction extend beyond the conveyor belts 102b-2 on both sides, so that the handling device lifts the battery cell from bottom to top and separates it from the second conveyor member 102b.

[0047] The structures of the first transmission member 101a and the third transmission member 101b are the same as the structure of the second transmission member 102b. The length of the first transmission member 101a and the third transmission member 101b along the battery cell transmission direction is greater than the length of the second transmission member 102b along the battery cell transmission direction.

[0048] Since each of the second transmission members 102b is placed corresponding to a half-cell, it can be understood that the length of the second transmission member 102b along the cell transmission direction is equivalent to the width of the half-cell. The first transmission member 101a and the third transmission member 101b are mainly used to transmit cells, and their lengths along the cell transmission direction are not limited by the width of the half-cell. Therefore, compared with the second transmission member 102b, the lengths of the first transmission member 101a and the third transmission member 101b along the cell transmission direction can be lengthened, so that the transmission area 101 can transmit cells and reduce the transmission cost.

[0049] The loading area 102 further includes a sensor 102c for detecting the position of the half-cell battery sheet on the second transmission member 102b. The sensor 102c and the second transmission member 102b are arranged one by one, and the sensor 102c detects the position of the half-cell battery sheet on each second transmission member 102b, and controls the operation of each second transmission member 102b to adjust the position of the battery sheet thereon, so that the battery sheets are arranged in the loading area 102 according to the preset spacing. The sensor 102c can be a laser sensor that can locate the position of the half-cell battery sheet.

[0050] The present invention aims to reduce the number of printing heads and improve the printing efficiency of half-cells, so that two half-cells can share one printing head, that is, two printing areas are set on one printing head to screen print two half-cells at the same time. It can be understood that if two half-cells are to share one printing head, firstly, the spacing between the two half-cells needs to be reduced, and secondly, the consistency between the spacing between the two half-cells and the spacing between the two printing areas on the printing head needs to be ensured.

[0051] On this basis, the present invention further provides a feeding method, which is applied to the above-mentioned feeding device 100, comprising the following steps:

[0052] Place a half-cell battery on the first transmission member 101a, and make the width direction of the half-cell battery consistent with the transmission direction of the first transmission member 101a;

[0053] The half-cell battery is transferred to each group of loading positions 102a in the loading area 102 by the first transmission member 101a, and any group of the loading positions 102a includes two second transmission members 102b which are separately arranged;

[0054] A half-cell battery is placed on each of the second transmission members 102 b , and the positions of the half-cell batteries on each of the second transmission members 102 b are adjusted so that the half-cell batteries are arranged at a preset interval.

[0055] First, in order to reduce the distance between two half-cells, the present invention replaces the existing two transmission lines for feeding with one transmission line for feeding; at the same time, the present invention changes the placement direction of the existing half-cell during transmission, so that the width direction of the half-cell and the transmission direction are kept consistent, thereby avoiding the shape of the print head being too narrow and long, affecting the printing and structural stability of the print head.

[0056] Secondly, in order to ensure the consistency of the spacing between the two half-cell battery cells and the spacing between the two printing areas on the print head, two separately arranged second transmission components 102b are used to place the two half-cell battery cells respectively. Each of the second transmission components 102b can be individually controlled to adjust the position of the upper half-cell battery cell, so that the two half-cell battery cells located in the same loading position 102a are arranged according to a preset spacing, which is the preset spacing between the two printing areas on the print head.

[0057] The following reference Figure 5 and Figure 6 The feeding device 100 shown in the figure is used to explain the feeding method provided by the present invention in detail, which comprises the following steps:

[0058] S1, transferring a half-cell to the third transfer member 101b via the first transfer member 101a;

[0059] S2, correcting the posture of the half-cell battery sheet through the third transmission member 101b and transmitting it to the loading area 102;

[0060] S3. The half-cell battery is transferred to each of the second transfer members 102b. Each of the second transfer members 102b performs position correction on the half-cell battery thereon so that the half-cell battery is arranged according to a preset spacing.

[0061] In step S1, generally speaking, the first transmission member 101a transmits two half-cells each time. When placing the half-cells, it is necessary to ensure that the width direction of the half-cells is consistent with the transmission direction of the first transmission member 101a.

[0062] In step S2, when the half-cell battery is transferred to the area where the correction member 101b-1 is located, the correction member 101b-1 is turned on to correct the half-cell battery, so that the half-cell battery remains in a centered state on the third transmission member 101b and is transferred to each of the second transmission members 102b in this state.

[0063] In step S3, the half-cell battery is sequentially transferred to each of the second transfer members 102b, and a half-cell battery is placed on each of the second transfer members 102b. The sensor 102c detects the position of the half-cell battery on the second transfer member 102b, and controls the operation of each of the second transfer members 102b to adjust the position of the half-cell battery on the second transfer member 102b, so that the half-cell battery is arranged in the loading area 102 according to the preset spacing. That is, the spacing between the two half-cell battery in the same loading position 102a is equal to the spacing between the two printing areas on the printing head.

[0064] In a specific embodiment, the distance between the two printing areas on the printing head is ΔL1, the width of the half-cell is L, and the distance between the center lines of the two second transmission members 102b in the same group of the loading position 102a along the transmission direction is L1, wherein L1=L+ΔL1. In this way, as long as the center axis of the half-cell on each second transmission member 102b along the width direction is adjusted to coincide with the center line of the second transmission member 102b, the distance between the two half-cells in the same loading position 102a can be equal to the distance between the two printing areas on the printing head.

[0065] Reference Figure 3 and Figure 6, the loading position 102a is provided with two groups, that is, the loading area 102 of the feeding device has four second transmission members 102b separately provided. Combined with the above discussion, the second transmission member 1 and the second transmission member 2 are located in the same group of the loading position 102a, the center line distance between the two is L1, and the two half-cell battery cells on the second transmission member 1 and the second transmission member 2 share a printing head. The second transmission member 3 and the third transmission member 4 are located in the same group of the loading position 102a, the center line distance between the two is L1, and the two half-cell battery cells on the second transmission member 3 and the second transmission member 4 share a printing head.

[0066] It is understandable that two printing heads require two printing platforms. In order to realize the transfer of four battery cells to two printing platforms at one time through the transfer device, a certain distance needs to be maintained between the two printing platforms. In this way, compared with the two half-cell battery cells located in the same loading area 102, the distance between the two half-cell battery cells on the second transmission member 2 and the second transmission member 3 needs to be appropriately increased by ΔL2, that is, ΔL2>ΔL1.

[0067] On this basis, the spacing between the second transmission member 2 and the second transmission member 3 can be increased, and the spacing between the center line of the second transmission member 2 along the battery cell transmission direction and the center line of the second transmission member 3 along the battery cell transmission direction is L2, so that L2 = L + ΔL2. In this way, as long as the center axis of the half-cell battery cell on each second transmission member 102b along the width direction is adjusted to coincide with the center line of the second transmission member 102b, the half-cell battery cell can be arranged according to the preset spacing.

[0068] Of course, in other embodiments, the spacing between the second transmission members 102b can also be kept the same, that is, L1 = L2. In this way, after aligning the central axis of each half-cell battery along the width direction with the center line of each second transmission member 102b, it is necessary to control the half-cell battery in one of the two groups of the loading areas 102 to move away from the half-cell battery in the other group, thereby increasing the spacing between the two half-cell battery on the second transmission member 2 and the second transmission member 3, so that the half-cell battery is arranged according to the preset spacing.

[0069] In summary, the present invention transmits half-cell batteries through a single transmission line, and arranges the half-cell batteries in the loading area 102 according to a preset spacing through the second transmission component 102b which is separately arranged, so that two half-cell batteries can share one printing head, thereby reducing the number of printing heads and improving the printing efficiency of half-cell batteries.
