Description

Technical Field

[0001] This utility model belongs to the technical field of battery cell testing and sorting equipment, specifically relating to battery cell sorting device and transmission mechanism. Background Technology

[0002] With the rapid development of the photovoltaic industry, cell sorting machines are indispensable in automated production lines for producing solar cells. Most current mainstream technologies adopt a dual-cell transport mechanism, in which solar cells are transported and sorted in pairs through symmetrically arranged conveyor belts or roller systems.

[0003] This approach typically uses a single drive motor to power two parallel transport modules, employing gears or belts to synchronously transport silicon wafers to subsequent inspection or processing stations. However, as the photovoltaic industry's capacity requirements continue to increase, the existing dual-wafer transport architecture has revealed significant shortcomings.

[0004] In terms of efficiency, dual-wafer transfer can only process two silicon wafers at a time, resulting in limited throughput per unit time. This cannot meet the high-cycle demands of modern production lines, creating a bottleneck effect, especially in the sorting process. Secondly, in terms of structural design, since the two transfer units are driven by a single motor, the gear or belt drive system is prone to asynchrony problems, causing cell misalignment or mispositioning. This not only reduces yield but also increases equipment maintenance frequency.

[0005] Therefore, a cell sorting device and transmission mechanism are designed to solve the technical problem of cell misalignment caused by asynchronous transmission systems when a single motor drives multiple transmission units in the prior art.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0028] Research has revealed that existing solar cell transport systems employ a dual-cell transport mechanism, where cells are transported and sorted in pairs via symmetrically arranged conveyor belts or roller systems. This approach typically uses a single drive motor to power two parallel transport modules, utilizing gears or belts to synchronously transport the silicon wafers to subsequent inspection or processing stations. However, with the photovoltaic industry's ever-increasing capacity requirements, the existing dual-cell transport architecture has exposed significant shortcomings.

[0029] In terms of efficiency, dual-wafer transfer can only process two silicon wafers at a time, resulting in limited throughput per unit time. This cannot meet the high-cycle demands of modern production lines, creating a bottleneck effect, especially in the sorting process. Secondly, in terms of structural design, since the two transfer units are driven by a single motor, the gear or belt drive system is prone to asynchrony problems, causing cell misalignment or mispositioning. This not only reduces yield but also increases equipment maintenance frequency.

[0030] Based on the above research, this disclosure provides a battery cell sorting device and a transmission mechanism. By setting up four battery cell transmission components, each battery cell transmission component is equipped with an independent conveyor motor. Each conveyor motor drives a corresponding conveyor belt to transport the corresponding battery cell, thus solving the problem of battery cell displacement deviation caused by multi-cell linkage.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the number of battery cell conveying assemblies 10 is preferably four. Before the battery cell 4 is conveyed, the four battery cells 4 are placed on the upper surface of the corresponding conveyor belts 105. Then, each conveyor motor 100 is started, and the output end of each conveyor motor 100 drives the corresponding transmission wheel 101 to rotate. Through the drive belt 102, the driven wheel 106 and the rotating shaft 103 are rotated, which in turn drives the conveyor belts 105 sleeved on the outer walls of the two rotating shafts 103 to rotate, thereby realizing the conveying of the corresponding battery cell 4. Each conveyor belt 105 is driven independently by the corresponding conveyor motor 100, which completely solves the problem of battery cell displacement deviation caused by multi-cell linkage. Figure 2 As shown in the figure, there are four cell delivery assemblies 10, with each pair of cell delivery assemblies 10 forming a group. Figure 2 Part A, Figure 2 Part B is the two-cell delivery assembly 10 in another group, which is composed of... Figure 2 It can be seen that the A and B groups are arranged symmetrically, which reduces the width of the equipment by 30% and significantly reduces the cost of the production line floor space.

[0035] In some embodiments, such as Figure 1 and Figure 3 As shown (there are two transplanting mechanisms 2), Figure 3 Only one of the transplanting mechanisms 2 is shown. When each conveyor belt 105 transports the corresponding battery cell 4 to the area below the corresponding adsorption plate 200, a vacuum device generates negative pressure at the vacuum hole 201 through the vacuum pipe 202, thereby adsorbing the battery cell 4 below each adsorption plate 200. Each transplanting mechanism 2 is equipped with two adsorption plates 200. Two transplanting mechanisms 2 are configured with four adsorption plates 200 corresponding to four battery cells 4. After each adsorption plate 200 has finished adsorbing, the control shift motor 22 is started, and its output end drives the base 23 along the guide direction of the slide rail 25 (i.e., Figure 3 The reciprocating motion (in the direction marked F) moves, thereby moving the T-shaped seat 24 fixed to the base 23, which in turn moves the corresponding battery cell 4 adsorbed by each adsorption plate 200 to the top of the corresponding bearing adsorption plate 33.

[0036] In some embodiments, such as Figure 1 and Figure 4As shown, when each battery cell 4 moves above the corresponding adjustment plate 33, the suction device stops working, and the negative pressure suction at the suction port 201 is no longer generated. Each battery cell 4 falls above the corresponding adjustment plate 33 under gravity and is supported by the corresponding support suction cup 34. At this time, the spacing between each battery cell 4 is adjusted by controlling the X-axis linear battery 30 to start adjusting the spacing between each Y-axis linear motor 31. The Y-axis linear motor 31 adjusts the position of each battery cell 4 in the Y-axis direction by controlling the position of each rotary motor 32 in the Y-axis direction. Each rotary motor 32 is suitable for adjusting the deflection angle of each battery cell 4 so that the position of each battery cell 4 is adjusted to meet the detection needs of the subsequent detection process.

[0037] In some embodiments, such as Figure 1 and Figure 3 As shown, in conjunction with the above description, when the shift motor 22 completes its initial reciprocating motion, the lifting cylinder 210, after the T-shaped seat 24 has initially reset, is positioned above the battery cell 4 that was initially adsorbed (i.e., above each adjusting plate 33). At this time, each adsorption plate 200 adsorbs the next battery cell 4, and simultaneously the lifting cylinder 210 starts, its output end driving the lifting plate 212 to move downward. Several lifting suction cups 213 provided on the lower end face of the lifting plate 212 adsorb the battery cells 4 that have been adjusted in position. Subsequently, the lifting cylinder 210 resets and lifts each battery cell 4. As the shift motor 22 starts again, the adsorption plate 200 moves the subsequent battery cell to above each adjusting plate 33, while the lifting plate 212 moves the battery cell 4 adsorbed by the lifting suction cups 213 to the subsequent processing position 5, and the corresponding battery cell 4 is removed by the device around the subsequent processing position 5 (how the battery cell 4 is removed is existing technology and will not be described in detail here); this process is repeated to achieve the sorting and processing of several battery cells 4.

[0038] It should be noted that the air extraction device mentioned in the above embodiments includes, but is not limited to, existing devices such as air extraction machines. The existing technology of generating negative pressure suction at the air extraction port 201 through the air extraction pipe 202 will not be described in detail here. The control of the base 23 by the shift motor 22 to move back and forth on the slide rail 25 and the connection method between the shift motor 22 and the base 23 are all existing technologies and will not be described in detail here.

[0039] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0041] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0042] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
