Description

Technical Field

[0001] This utility model relates to the field of battery string repair technology, and in particular to a battery string repair machine. Background Technology

[0002] As a promising new high-efficiency battery technology, stacked-grid solar cells face unique challenges in their industrialization process. Existing repair equipment cannot effectively handle faults in stacked-grid solar cell strings, resulting in high process losses and severely hindering project progress. Currently, the repair of defective solar cell strings mainly relies on manual disassembly and repair, but manual operation is cumbersome and inefficient. Utility Model Content

[0003] Therefore, it is necessary to provide a battery string repair machine to address the problems of cumbersome operation and low repair efficiency in the existing technology of manually repairing defective battery strings.

[0004] The technical solution is as follows:

[0005] On the one hand, a battery string repair machine is provided, including:

[0006] Base;

[0007] The disassembly mechanism includes a first platform mounted on the base and a second platform that moves and cooperates with the base in a direction close to or away from the first platform. The first platform and the second platform are spaced apart and are respectively used to support and fix the two ends of the battery string to be repaired.

[0008] A cell disassembly mechanism is installed on the base and is used to heat the battery cells located between the first platform and the second platform in the battery string to be repaired, so that the battery string to be repaired can be disassembled into at least one defective battery cell and at least one good battery string segment.

[0009] A welding mechanism, mounted on the base, is used to weld replacement battery cells and each of the good battery string segments in series to obtain a repaired battery string.

[0010] In the battery string repair machine described in the above embodiments, the defective battery cells in the battery string to be repaired are first placed between a first platform and a second platform, with both ends of the battery string placed on the first and second platforms respectively and fixed accordingly. Next, a disassembly mechanism heats the defective battery cells. Then, when the disassembly mechanism heats the defective battery cells for a preset time, it drives the second platform to move away from the first platform, causing the battery string to be repaired to separate into good battery string segments and defective battery string segments. This process is repeated to disassemble the defective battery string segments until the battery string to be repaired is disassembled into at least one defective battery cell and at least one good battery string segment. Finally, a welding mechanism is used to reconnect and weld the replacement battery cells and each good battery string segment in series, resulting in a usable repaired battery cell. Compared with the prior art of manually repairing defective battery strings, the battery string repair machine of this application can realize the disassembly and repair of the battery string to be repaired, reducing manual labor intensity, increasing repair efficiency, reducing process losses, and reducing the production volume of the battery string itself.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the first platform and / or the second platform includes at least one platform body and at least one connector. Each platform body is configured to correspond to each battery cell in the battery string to be repaired.

[0014] In one embodiment, the battery string repair machine further includes a detection component and a controller. The controller is communicatively connected to the detection component, the first drive component, and the chip removal mechanism. The detection component is used to detect whether the two ends of the battery string are respectively fixed on the first platform and the second platform.

[0015] In one embodiment, the base is provided with a mounting frame, and a chip removal station is formed between the first platform and the second platform.

The first movable member is located above the chip removal station and moves in cooperation with the mounting frame. The first telescopic member is installed on the first movable member and is connected to the chip removal mechanism in a transmission manner. The first telescopic member is used to drive the chip removal mechanism to reciprocate in a direction that approaches or moves away from the chip removal station.

[0016] In one embodiment, the battery string repair machine further includes a second telescopic member, which is mounted on the first movable member and is connected to the welding mechanism in a transmission manner. The second telescopic member is used to drive the welding mechanism to reciprocate in a direction that approaches or moves away from the base.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 As shown, in one embodiment, a battery string repair machine 10 is provided, including a base 100, a disassembly mechanism 200, a chip removal mechanism 300, and a welding mechanism 400. The disassembly mechanism 200 includes a first platform 210 mounted on the base 100, and a direction relative to the base 100 along a path close to or away from the first platform 210 (e.g., ...). Figure 1 A second platform 220 (shown in direction A) moves and engages with the battery string. The first platform 210 and the second platform 220 are spaced apart and respectively used to support and fix the two ends of the battery string to be repaired. A cell disassembly mechanism 300 is mounted on the base 100 and is used to heat the battery cells located between the first platform 210 and the second platform 220 within the battery string to be repaired, so that the battery string to be repaired can be disassembled into at least one defective battery cell and at least one good battery string segment. A welding mechanism 400 is mounted on the base 100 and is used to weld the replacement battery cell and each good battery string segment in series to obtain the repaired battery string.

[0030] In the battery string repair machine 10 described in the above embodiment, during use, the defective battery cell from the battery string to be repaired is first placed between the first platform 210 and the second platform 220, with both ends of the battery string to be repaired placed on the first platform 210 and the second platform 220 respectively and fixed accordingly. Next, the chip removal mechanism 300 heats the defective battery cell. Then, when the chip removal mechanism 300 heats the defective battery cell to a preset time, it drives the second platform 220 to move away from the first platform 210, causing the battery string to be repaired to separate into good battery string segments and defective battery string segments. This process is repeated to disassemble the defective battery string segments until the battery string to be repaired is disassembled into at least one defective battery cell and at least one good battery string segment. Finally, the welding mechanism 400 reconnects and welds the replacement battery cell and each good battery string segment in series to obtain a usable repaired battery cell. Compared with the existing technology of manually repairing defective battery strings, the battery string repair machine 10 of this application can disassemble and repair the battery strings to be repaired, thereby reducing the intensity of manual labor, increasing repair efficiency, reducing process losses, and reducing the production volume of battery strings.

[0031] It should be noted that a solar cell includes the cell body and a connecting strip welded to the cell body at one end. Solar cells are divided into two categories: good solar cells and defective solar cells. A replacement solar cell refers to a good solar cell used to replace a defective solar cell. A good solar cell segment refers to a segment of solar cells that includes at least one good solar cell and is welded in series.

[0032] It should be noted that when disassembling the defective battery string segment, the defective battery cell located at the outermost end of the defective battery string segment is placed and fixed on the first platform 210 or the second platform 220, and the battery cell between the first platform 210 and the second platform 220 is a good battery cell that is welded to the defective battery cell.

[0033] like Figure 1 and Figure 2 Optionally, the first platform 210 and / or the second platform 220 include at least one platform body 211 and at least one connector 212. Each platform body 211 is correspondingly disposed to each battery cell in the battery string to be repaired. At least a portion of the platform body 211 is provided with a fixing part for fixing the battery cell. Two adjacent platform bodies 211 are connected by the connector 212.

[0034] The number of platform bodies 211 and connectors 212 in the first platform 210 and the number of platform bodies 211 and connectors 212 in the second platform 220 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, adjacent platform bodies 211 in the first platform 210 are fixedly connected by connectors 212, forming an integrated structure. Similarly, adjacent platform bodies 211 in the second platform 220 are fixedly connected by connectors 212, forming an integrated structure. The first platform 210 includes twelve platform bodies 211, and the second platform 220 includes six platform bodies 211.

[0035] Specifically, in this embodiment, the connector 212 is configured as a connector block, and two adjacent platform bodies 211 can be fixedly connected as one unit by snap-fit, plug-in, screw-in, or other means. The platform body 211 is configured as a disassembly and transfer platform, and each disassembly and transfer platform can cooperate to transfer the battery strings to be repaired, reducing the intensity of manual labor and improving the practicality of the battery string repair machine 10.

[0036] In this specific embodiment, the fixing part is configured as a vacuum hole. Each platform body 211 is provided with at least one vacuum hole, one end of which extends to the upper surface of the corresponding platform body 211, and the other end is used to communicate with a vacuuming device. In this way, while ensuring that each battery cell in the battery string to be repaired is stably fixed on its corresponding platform body 211, damage to the battery cells by the platform body 211 is avoided, thereby improving the repair yield of the battery string repair machine 10.

[0037] In other embodiments, the fixing part can also be configured as a fixing block, a fixing buckle, or other fixing structure. The number of platform bodies 211 with fixing parts and the number of fixing parts on a single platform body 211 can be adjusted according to actual usage needs.

[0038] like Figure 1 As shown, in one embodiment, the disassembly mechanism 200 further includes a first driving member 230. The first driving member 230 is connected to the second platform 220 and is controlled to drive the second platform 220 to reciprocate in a direction approaching or moving away from the first platform 210. In this way, the first driving member 230 can accurately and quickly drive the second platform 220 to reciprocate between the heating position and the disassembly position, improving the repair efficiency of the battery string repair machine 10.

[0039] The first driving component 230 can be configured as a telescopic cylinder, an electric telescopic rod, or other driving structure.

[0040] like Figure 1As shown, optionally, the battery string repair machine 10 also includes a detection component and a controller 500. The controller 500 is communicatively connected to the detection component, the first drive unit 230, and the chip removal mechanism 300. The detection component is used to detect whether the two ends of the battery string are respectively fixed on the first platform 210 and the second platform 220. In this way, by determining whether the two ends of the battery string to be repaired are respectively fixed on the first platform 210 and the second platform 220 through the detection component, it is ensured that the battery string to be repaired on the first platform 210 and the battery string to be repaired on the second platform 220 can be separated when the first drive unit 230 pushes the second platform 220 in a direction away from the first platform 210, thereby improving the reliability of the battery string repair machine 10.

[0041] Optionally, at least one detection component is used, and each platform body 211 is equipped with a detection component. Specifically, in this embodiment, the detection component can be a photoelectric adsorption detection component. In other embodiments, the detection component can also be an infrared sensor, etc.

[0042] The controller 500 can be configured as a microcontroller, control panel, or other control structure. The number of controllers 500 can be flexibly adjusted according to actual needs. The controller 500 can communicate with the detection component, the first drive component 230, and the chip removal mechanism 300 via data cable, power cable, Bluetooth, wireless network communication technology, or other solutions.

[0043] like Figure 1 As shown, optionally, a mounting bracket 610 is provided on the base 100. The mounting bracket 610 spans the disassembly mechanism 200. The battery rework machine 10 also includes a mounting base plate 650 mounted on the mounting bracket 610. The controller 500 is configured as a control panel, which is mounted on the mounting base plate 650.

[0044] Specifically, in this embodiment, the mounting bracket 610 includes two uprights and two connecting plates. The two uprights are respectively fixed to both sides of the base 100 along the moving direction of the second platform 220. The two connecting plates are spaced apart along the length of the uprights and extend along the moving direction of the second platform 220. Both ends of the two connecting plates are fixedly connected to the tops of the two uprights. The mounting base plate 650 is installed at the middle position of the two connecting plates.

[0045] like Figure 1 As shown, in this specific embodiment, casters 110 are installed at the four corners of the bottom of the base 100. In this way, the casters 110 can increase the flexibility of the base 100, thereby improving the ease of movement of the battery string repair machine 10.

[0046] like Figure 1As shown, in one embodiment, a stripping station is formed between the first platform 210 and the second platform 220. The battery rework machine 10 also includes a first movable member 620 and a first telescopic member 630. The first movable member 620 is located above the stripping station and moves in cooperation with the mounting frame 610. The first telescopic member 630 is mounted on the first movable member 620 and is drively connected to the stripping mechanism 300. The first telescopic member 630 is used to drive the stripping mechanism 300 in a direction approaching or away from the stripping station (e.g., ...). Figure 1 (As shown in direction B) It moves back and forth. In this way, the position of the chip removal mechanism 300 can be flexibly adjusted by the cooperation of the first movable part 620 and the first telescopic part 630, so as to ensure that the chip removal mechanism 300 can avoid other parts when heating is not required, avoid interference between the chip removal mechanism 300 and other parts, and improve the reliability of the battery string repair machine 10.

[0047] The first movable member 620 can be configured as a movable seat, movable block, or other movable member. The first telescopic member 630 can be configured as a telescopic cylinder, electric telescopic rod, or other telescopic structure. The disassembly mechanism 300 can be configured as any of the existing disassembly structures for heating and disassembling battery strings. Specifically, in this embodiment, the disassembly mechanism 300 includes a disassembly welding knife.

[0048] Specifically, in this embodiment, the movable frame is provided with a fixed guide rail extending along the moving direction of the second platform 220. The first movable component 620 moves in conjunction with the fixed guide rail. The battery rework machine 10 also includes a second driving component communicatively connected to the controller 500. The second driving component is mounted on the mounting bracket 610. The second driving component is drively connected to the first movable component 620 and is controlled to drive the first movable component 620 to reciprocate along the moving direction of the second platform 220. In this way, the second driving component can accurately and quickly drive the first movable component 620 to reciprocate between the working position and the avoidance position, improving the rework efficiency of the battery rework machine 10.

[0049] The second driving component can be configured as a telescopic cylinder, an electric telescopic rod, or other driving structure.

[0050] like Figure 1 As shown, optionally, the battery rework machine 10 also includes a second telescopic member 640. The second telescopic member 640 is mounted on the first movable member 620 and is drive-connected to the welding mechanism 400. The second telescopic member 640 is used to drive the welding mechanism 400 in a direction approaching or away from the base 100 (e.g., ...). Figure 1 (As shown in direction B) Reciprocating movement. In this way, the chip removal mechanism 300 and the welding mechanism 400 share the first moving part 620 and the second driving part, reducing the manufacturing cost of the battery string repair machine 10.

[0051] The second telescopic member 640 can be configured as a telescopic cylinder, an electric telescopic rod, or other telescopic structure. The welding mechanism 400 can be configured as any of the prior art welding structures for series welding between battery cells. Specifically, in this embodiment, the welding mechanism 400 includes a welding blade. The first telescopic member 630 and the second telescopic member 640 are installed at intervals on the bottom of the first movable member 620 along the moving direction of the second platform 220. The cell removal mechanism 300 is installed on the bottom of the first telescopic member 630, and the welding mechanism 400 is installed on the bottom of the second telescopic member 640.

[0052] It should be noted that the welding mechanism 400 can use the fully automatic method of the prior art to weld the replacement battery cells and each good battery string in series, or it can use the semi-automatic method combined with manual method of the prior art to weld the replacement battery cells and each good battery string in series. This will not be elaborated on here.

[0053] like Figure 1 As shown, in one embodiment, a testing station is provided on the base 100. The battery string repair machine 10 also includes a testing mechanism 700. The testing mechanism 700 is installed at the testing station and configured to detect the position of defective battery cells in the battery string to be repaired when it is placed at the testing station. In this way, the testing mechanism 700 can detect the position of defective battery cells in the battery string to be repaired, thereby facilitating the subsequent placement of defective battery cells between the first platform 210 and the second platform 220, improving the practicality of the battery string repair machine 10.

[0054] The detection mechanism 700 can be any existing detection structure capable of detecting the location of defective cells in the battery to be repaired. The number of detection mechanisms 700 can be flexibly adjusted according to actual usage needs.

[0055] Specifically, in this embodiment, the detection mechanism 700 is communicatively connected to the controller 500. There are two detection mechanisms 700, spaced apart, and both are configured as EL (Electroluminescence) testing modules. The two EL testing modules are configured to be energized at both ends of the battery string to be repaired when it is placed on the base 100, in order to detect the location of defective cells in the battery string.

[0056] like Figure 1 and Figure 3As shown, the battery rework machine 10 further includes a second movable member 660 and a third telescopic member 670. The second movable member 660 is located above the inspection station and moves in coordination with the mounting bracket 610. The third telescopic member 670 is mounted on the second movable member 660 and is drively connected to the inspection mechanism 700. The third telescopic member 670 is used to drive the inspection mechanism 700 in a direction closer to or farther from the inspection station (e.g., ...). Figure 1 (As shown in direction B) It moves back and forth. In this way, the position of the detection mechanism 700 can be flexibly adjusted by the cooperation of the second movable part 660 and the third telescopic part 670, so as to ensure that the detection mechanism 700 can be set to correspond to the end of different battery strings to be repaired, thereby improving the detection adaptability.

[0057] Specifically, in this embodiment, there are two second movable members 660 and two third telescopic members 670. The two second movable members 660 are respectively installed at both ends of the connecting plate. The two third telescopic members 670 are respectively installed at the bottom of the two second movable members 660, and the two EL test modules are respectively installed at the bottom of the two third telescopic members 670.

[0058] Specifically, in this embodiment, the second movable member 660 is configured as a slide table, which is located between the two connecting plates and slides with both connecting plates along the moving direction of the second platform 220. Fixed guide rails are provided on the sides of the two connecting plates that are far apart from each other, and both fixed guide rails move in conjunction with the first movable member 620.

[0059] like Figure 1 and Figure 3 As shown, optionally, the battery rework machine 10 also includes a locking member 680. The locking member 680 is mounted on the second movable member 660 and is used to lock and fix the second movable member 660 to the mounting bracket 610. In this way, the locking member 680 can quickly fix the second movable member 660, thereby increasing the fixing strength between the second movable member 660 and the mounting bracket 610, ensuring that the second movable member 660 will not move relative to the mounting bracket 610 during the operation of the detection mechanism 700, and improving the reliability of the battery rework machine 10.

[0060] The locking element 680 can be configured as a locking latch, locking pin, locking bolt, or other locking structure. The number of locking elements 680 can be flexibly adjusted according to actual usage needs.

[0061] Specifically, in this embodiment, the second movable member 660 is provided with a threaded through hole, which extends to the side of the second movable member 660 facing the mounting bracket 610. The locking member 680 is provided as a locking bolt, which passes through the threaded through hole and abuts against the mounting bracket 610.

[0062] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 application.

[0063] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0066] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0067] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
