Description

Technical field

[0001] The utility model belongs to the technical field of silicon wafer manufacturing equipment, in particular to a transfer material receiving mechanism and a lifting transfer device for a half-sheet guide of a battery. [Background Technology]

[0002] During the manufacturing process, solar cells undergo a series of processing steps, including cleaning and coating. Cells are typically placed in baskets, which serve as carriers for transport between the various processes. During coating, cells are transferred from the baskets to a graphite boat. To ensure that each cell entering the coating equipment is intact, cells are typically removed from the baskets one by one and transported through a conveyor line. Visual cameras can be installed on the conveyor line for inspection. The intact cells are then collected one by one and stacked at intervals in the height direction. A transport mechanism then suctions and transports the entire row of cells to the graphite boat, which then carries the cells into the coating equipment for coating.

[0003] To achieve the above process, prior art patent CN116495472B discloses a tubular PECVD conveyor device and method. This device utilizes a lower feed assembly to receive battery cells conveyed from a conveyor line. Once the lower feed assembly is loaded with a set number of battery cells, it rises to a set height. An upper feed assembly, located at a higher position, receives an entire row of battery cells, which are then transferred from the lower feed assembly to the upper feed assembly. The lower feed assembly then descends for the next round of feed. The upper feed assembly then aligns the entire row of cells before waiting for a transport mechanism to remove them and place them in a graphite boat. However, this conveyor device can only transfer whole-cell battery cells and is not directly applicable to transferring half-cell battery cells. For half-cells, a single conveyor unit typically transports two rows of half-cells. During the transfer process, both rows or columns of half-cells are simultaneously shifted. However, the spacing between the two rows or columns of half-cells is small, limiting both receiving and aligning them. This makes the structural design of the corresponding transfer mechanism quite challenging.

[0004] Therefore, it is necessary to provide a new intermediate material transfer mechanism and lifting transfer device for battery half-sheet guides to solve the above technical problems. [Utility Model Content]

[0005] One of the main purposes of the present invention is to provide a transfer splicing mechanism for a half-cell guide of a battery, which can be applied to the transfer splicing and alignment of the half-cell during the transfer process.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: a transfer material receiving mechanism for a half-sheet guide of a battery, comprising a second support plate, a third material receiving unit and a fourth material receiving unit arranged side by side on the second support plate; the third material receiving unit and the fourth material receiving unit both comprise a left support assembly and a right support assembly; the left support assembly in the third material receiving unit and the fourth material receiving unit are jointly fixedly arranged on the third support plate, the right support assembly in the third material receiving unit and the fourth material receiving unit are jointly fixedly arranged on the fourth support plate, and the second support plate is provided with a third cylinder for driving the third support plate to move left and right, and a fourth cylinder for driving the fourth support plate to move left and right.

[0007] Furthermore, the left support assembly and the right support assembly each include at least two second support uprights and a plurality of second support shafts that are equidistantly arranged on the second support uprights along the up-down direction.

[0008] Furthermore, it also includes a first correction unit for correcting the positions of the left and right sides of a column of battery half sheets in the third receiving unit and a second correction unit for correcting the positions of the left and right sides of a column of battery half sheets in the fourth receiving unit.

[0009] Furthermore, the first correction unit and the second correction unit both include a left correction component and a right correction component; the left correction components in the first correction unit and the second correction unit are jointly fixed on the fifth support plate, and the right correction components in the first correction unit and the second correction unit are jointly fixed on the sixth support plate, and the second support plate is provided with a fifth cylinder for driving the fifth support plate to move left and right, and a sixth cylinder for driving the sixth support plate to move left and right.

[0010] Furthermore, the left-side correction component and the right-side correction component each include at least two third support uprights and a correction plate fixedly arranged on the third support uprights.

[0011] Another object of the present invention is to provide a battery half-cell lifting and transferring device, which is characterized in that it includes a material receiving and lifting mechanism for docking with a conveyor line for receiving materials and the transfer material receiving mechanism as described above; the transfer material receiving mechanism docks with the battery cell adsorption and conveying mechanism and is arranged above the material receiving and lifting mechanism.

[0012] Furthermore, the material receiving and lifting mechanism includes a lifting module, a first support plate driven by the lifting module to move up and down, a first material receiving unit and a second material receiving unit arranged on the first support plate, and a first cylinder for adjusting the distance between the first material receiving unit and the second material receiving unit; when the first material receiving unit and the second material receiving unit are in a separated state, the first material receiving unit is located directly below the third material receiving unit, and the second material receiving unit is located directly below the fourth material receiving unit.

[0013] Furthermore, the first material receiving unit and the second material receiving unit both include a second cylinder and a pair of supporting components that are moved toward or apart from each other in the left-right direction by the second cylinder.

[0014] Furthermore, the support assembly includes at least two first support uprights and a plurality of first support shafts arranged on the first support uprights at equal intervals in the up and down directions; the left support assembly and the right support assembly each include at least two second support uprights; the first support uprights and the second support uprights are staggered in the front and back directions.

[0015] Furthermore, the material receiving lifting mechanism and the transfer material receiving mechanism constitute a set of lifting transfer modules, and at least two sets of the lifting transfer modules are arranged on the left and right.

[0016] Compared with the prior art, the beneficial effects of the utility model of a transfer material receiving mechanism and a lifting and transferring device for a half-cell guide of a battery are as follows: by cleverly designing the structure of the left and right support assemblies in the third material receiving unit and the fourth material receiving unit, two cylinders are used to complete the mutual approach and mutual opening movement of the two left support assemblies and the two right support assemblies, and the opening drive of the two groups of support assemblies is realized within a limited space; by utilizing the above principle, the driving of the left and right side return assemblies in the first and second return units to move towards and open each other is also realized within a limited space, which is suitable for the transfer and acceptance of half-cell battery sheets; in conjunction with the material receiving and lifting mechanism capable of realizing spacing adjustment, by adjusting the spacing between the first and second material receiving units, the first and second material receiving units can connect to the conveyor line to accept two rows of battery half-cells in a small spacing state, and enter the transfer material receiving mechanism in a large spacing state, so that there is enough gap for the support assemblies and the return assemblies in the transfer material receiving mechanism to perform opening and closing movements.

[Specific implementation method]

[0029] Example 1:

[0030] Please refer to Figures 1-8 This embodiment is a lifting and transferring device 100 for a half-cell guide of a battery, which includes a material receiving and lifting mechanism 1 for connecting to a conveyor line for receiving materials, and a transfer material receiving mechanism 2 arranged above the material receiving and lifting mechanism 1 and connecting to a battery cell adsorption and conveying mechanism.

[0031] The material receiving and lifting mechanism 1 includes a lifting module 11, a first support plate 12 driven by the lifting module 11 to move up and down, a first material receiving unit 13 and a second material receiving unit 14 arranged on the first support plate 12, and a first cylinder 15 for adjusting the distance between the first material receiving unit 13 and the second material receiving unit 14.

[0032] In this embodiment, the first material receiving unit 13 is fixedly arranged on the first support plate 12, and the second material receiving unit 14 is slidably arranged on the first support plate 12. The first cylinder 15 drives the second material receiving unit 14 to move left and right, thereby adjusting the distance between the second material receiving unit 14 and the first material receiving unit 13.

[0033] In another embodiment, the first receiving unit 13 and the second receiving unit 14 can also be slidably arranged on the first support plate 12, and the first cylinder 15 drives the first receiving unit 13 and the second receiving unit 14 to move closer to or apart from each other to adjust the distance between them.

[0034] The flower basket for carrying battery half-cells generally carries two rows of battery half-cells, and the spacing between the two rows of battery half-cells is small. After the battery half-cells are taken out of the flower basket and placed on the conveyor line, two rows of battery half-cells are formed (several battery half-cells horizontally spaced and distributed in the same direction constitute a row of battery half-cells), and the spacing between the two rows of battery half-cells is correspondingly small. The material receiving and lifting mechanism 1 receives the two rows of battery half-cells from the end of the conveyor line and forms two rows of battery half-cells again (several battery half-cells spaced and distributed up and down constitute a row of battery half-cells), and then rises and moves to the transfer material receiving mechanism 2, and the two rows of battery half-cells are transferred by the transfer material receiving mechanism 2. The battery halves are removed and transferred. Since the transfer receiving mechanism 2 needs to support the battery halves from the left and right sides when receiving the two rows of battery halves, two sets of support poles supporting one side of the battery halves need to enter the gap between the two rows of battery halves. Since many support shafts are generally provided on the support poles, the support shafts are used to support the bottom of the left and right sides of the battery halves. The two relatively distributed support poles need to be sufficiently spaced apart so that the support shafts are also located outside the side contours of the battery halves. Therefore, if the distance between the two rows of battery halves is too small, the support poles cannot be accommodated to enter smoothly. In order to solve this problem, this embodiment sets a first cylinder 15 to adjust the distance between the first receiving unit 13 and the second receiving unit 14, thereby increasing the distance between the two rows of battery halves so that the above-mentioned support poles can enter smoothly.

[0035] The first receiving unit 13 and the second receiving unit 14 have the same structure and both include a second cylinder 131 and a pair of supporting assemblies 132 that are moved toward or away from each other by the second cylinder 131 in the left-right direction.

[0036] The support assembly 132 includes at least two first support rods 1321 and a plurality of first support shafts 1322 equidistantly spaced vertically on the first support rods 1321. A pair of support assemblies 132 includes at least four first support rods 1321, located on the left and right sides of the battery half. The four first support shafts 1322 on the four first support rods 1321 support the bottom of the battery half, thereby providing support for the battery half.

[0037] The transfer material receiving mechanism 2 includes a third material receiving unit 21 corresponding to the first material receiving unit 13 above and below, a fourth material receiving unit 22 corresponding to the second material receiving unit 14 above and below, a first correction unit 23 for correcting the position of the left and right sides of a column of battery half sheets in the third material receiving unit 21, and a second correction unit 24 for correcting the position of the left and right sides of a column of battery half sheets in the fourth material receiving unit 22.

[0038] The first material receiving unit 13 and the second material receiving unit 14 are in a separated state. The first material receiving unit 13 is located directly below the third material receiving unit 21 , and the second material receiving unit 14 is located directly below the fourth material receiving unit 22 .

[0039] The transfer material receiving mechanism 2 further includes a fixed second support plate 25 , and the third material receiving unit 21 , the fourth material receiving unit 22 , the first correcting unit 23 and the second correcting unit 24 are all mounted on the second support plate 25 .

[0040] The third material receiving unit 21 and the fourth material receiving unit 22 have the same structure and both include a left support assembly 211 and a right support assembly 212; the left support assembly 211 in the third material receiving unit 21 and the fourth material receiving unit 22 is jointly fixedly set on the third support plate 213, and the right support assembly 212 in the third material receiving unit 21 and the fourth material receiving unit 22 is jointly fixedly set on the fourth support plate 214, and the second support plate 25 is provided with a third cylinder 215 for driving the third support plate 213 to move left and right, and a fourth cylinder 216 for driving the fourth support plate 214 to move left and right.

[0041] Each of the left and right support assemblies 211, 212 includes at least two second support rods 2111 and a plurality of second support shafts 2112 equally spaced vertically on the second support rods 2111. Each of the left and right support assemblies 211, 212 includes at least four second support rods 2111, located on the left and right sides of the battery half. The four second support shafts 2112 on the four second support rods 2111 support the bottom of the battery half, thereby providing support for the battery half.

[0042] The first correcting unit 23 and the second correcting unit 24 have the same structure and both include a left correcting component 231 and a right correcting component 232; the left correcting component 231 in the first correcting unit 23 and the second correcting unit 24 is jointly fixedly set on the fifth support plate 233, and the right correcting component 232 in the first correcting unit 23 and the second correcting unit 24 is jointly fixedly set on the sixth support plate 234, and the second support plate 25 is provided with a fifth cylinder 235 for driving the fifth support plate 233 to move left and right, and a sixth cylinder 236 for driving the sixth support plate 234 to move left and right.

[0043] The left and right alignment assemblies 231 and 232 have the same structure and both include at least two third support rods 2311 and alignment plates 2312 fixed to the third support rods 2311. Each of the left and right alignment assemblies 231 and 232 has at least four third support rods 2311, located on the left and right sides of the battery half, and on the front and back sides of the left and right support assemblies 211 and 212. The four alignment plates 2312 on the four third support rods 2311 are used to align the left and right positions of the battery cells.

[0044] In order to facilitate the first material receiving unit 13, the second material receiving unit 14 rises and enters the third material receiving unit 21 and the fourth material receiving unit 22 respectively, and each can flexibly switch between the open state and the supporting state, and the two return units can also switch between the return state and the open state; the first support rod 1321 in the first material receiving unit 13 and the second material receiving unit 14 is set at the innermost side in the front-to-back direction, the second support rod 2111 in the third material receiving unit 21 and the fourth material receiving unit 22 is located at the front and back outside of the first support rod 1321, and the third support rod 2311 in the first return unit 23 and the second return unit 24 is located at the front and back outside of the second support rod 2111, that is, the first support rod 1321, the second support rod 2111, and the third support rod 2311 are staggered in the front-to-back direction. Therefore, the above-mentioned support rods do not interfere with each other when moving left and right.

[0045] In order to improve the efficiency of loading and unloading cells when entering and exiting the coating equipment, two sets of lifting and transferring devices 100 can be configured, one set for feeding cells into the graphite boat, and the other set for taking cells out of the graphite boat, or the two sets can be used alternately to realize feeding and outputting materials.

[0046] The working process of the lifting and transferring device 100 for a half-cell guide of a battery in this embodiment is as follows:

[0047] When feeding is in use: the conveyor line conveys two rows of battery half-sheets to the receiving and lifting mechanism 1 at the end, and the first receiving unit 13 and the second receiving unit 14 are in the receiving state and are respectively aligned with the two rows of battery half-sheets. Each time a pair of battery half-sheets is received, the lifting module 11 drives the first receiving unit 13 and the second receiving unit 14 to rise to a set height; after the first receiving unit 13 and the second receiving unit 14 are full of two rows of battery half-sheets, the first cylinder 15 drives the second receiving unit 14 to move left and right, and increases the distance between the first receiving unit 13; then the lifting module 11 drives the first receiving unit 13 and the second receiving unit 14 to rise, and enter the third receiving unit 21 and the fourth receiving unit 22 respectively. The third receiving unit 21 and the fourth receiving unit 22 are in an open state in the initial state, and the first receiving unit 13 and the second receiving unit 1 are in an open state. After entering, the third receiving unit 21 and the fourth receiving unit 22 switch to the receiving state, the left supporting assembly 211 and the right supporting assembly 212 move closer to each other, the second support shaft 2112 extends under the two rows of battery half-cells, and the lifting drive module 11 drives the first receiving unit 13 and the second receiving unit 14 to descend a set distance, transferring the two rows of battery half-cells to the second support shaft 2112; then the first receiving unit 13 and the second receiving unit 14 switch to the open state and descend below the conveyor line to receive the next group of battery half-cells. At the same time, the first correcting unit 23 and the second correcting unit 24 switch from the open state to the correcting state, the left correcting assembly 231 and the right correcting assembly 232 move closer to each other, and the positions of the two rows of battery half-cells are corrected. Thereafter, the adsorption transport mechanism transports them to the graphite boat for coating loading.

[0048] When collecting and using: the adsorption and transport mechanism adsorbs two rows of battery half-cells and places them in the third receiving unit 21 and the fourth receiving unit 22, and the first correcting unit 23 and the second correcting unit 24 correct their positions; the first receiving unit 13 and the second receiving unit 14 move upward in an open state to the third receiving unit 21 and the fourth receiving unit 22, and receive the two rows of battery half-cells; then the third receiving unit 21 and the fourth receiving unit 22 switch to an open state, the first receiving unit 13 and the second receiving unit 14 carry the two rows of battery half-cells and descend to the top of the conveyor line, and then place the battery cells on the conveyor line in pairs to form two rows of battery half-cells, which are output and recovered into the flower basket by the conveyor line.

[0049] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
