Description

Technical Field

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

[0002] The production process of solar cells includes a screen printing step. Screen printing involves using a printing press to print a paste onto the front and back of the solar cell according to a screen pattern, forming the conductive grid lines. During the printing process, due to abnormalities such as the end of the screen's lifespan or mismatched printing equipment parameters, the printed conductive grid lines may occasionally break, resulting in quality defects that are not effectively detected by the naked eye. Currently, the industry's approach to dealing with these defective solar cells is to continue the entire printing process. This involves collecting the defective cells after testing and sorting, and then manually repairing the broken grid lines to reduce losses. However, existing repair methods for defective solar cells are inefficient, and the repair quality is affected by the experience and skills of the personnel, resulting in poor stability. Utility Model Content

[0003] Therefore, it is necessary to provide a battery cell grid line repair machine to address the problems of low repair efficiency and poor stability caused by the influence of personnel's work experience and skills on the repair quality of existing defective battery cells.

[0004] The technical solution is as follows:

[0005] On the one hand, a cell grid line repair machine is provided, comprising:

[0006] Positioning fixture, used to hold the piece to be repaired;

Then, the second and third moving modules jointly drive the repair module according to the position signal, so that the repair module moves to the broken grid position on the cells to be repaired. Next, the repair module starts to overflow the slurry, the first moving module drives the cells to be repaired along the first direction according to the position signal and through the positioning fixture, and the third moving module drives the repair module along the third direction according to the position signal, so that the repair module automatically completes the grid line repair on the cells to be repaired. Finally, after the repaired cell is repaired, the repair module stops overflowing slurry, the first, second, and third moving modules reset, and the positioning fixture resets to the loading position to facilitate the removal of the repaired cell and the repositioning of the unrepaired cell. The battery cell grid line repair machine of this application can automatically complete the grid line repair on the cell, effectively improving the grid line repair efficiency, repair accuracy, and repair quality stability, while reducing the labor intensity of operators.

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.

[0034] like Figure 1 As shown, in one embodiment, a battery cell grid line repair machine 10 is provided, including a positioning fixture 100, a first moving module 200, a repair module 300, a second moving module 400, a third moving module 500, and a detection module 600. The positioning fixture 100 is used to carry the cell to be repaired. The first moving module 200 is driven by the positioning fixture 100 and is used to drive the positioning fixture 100 to move along a first direction. The repair module 300 is located on one side of the positioning fixture 100 and is used to repair the grid lines on the cell to be repaired. The second moving module 400 is driven by the repair module 300 and is used to drive the repair module 300 to move along a second direction. The third moving module 500 is driven by the second moving module 400 and is used to drive the second moving module 400 to move along a third direction. The detection module 600 is communicatively connected to the first moving module 200, the second moving module 400, and the third moving module 500, and is configured to detect the broken grid position on the piece to be repaired when the positioning fixture 100 moves the piece to be repaired to the detection position. Any two of the first direction, the second direction, and the third direction are perpendicular.

[0035] In the above embodiment, the cell grid line repair machine 10 operates as follows: First, the first moving module 200 drives the positioning fixture 100 to the loading position, and then places the collected cells to be repaired onto the positioning fixture 100. Next, the first moving module 200 drives the positioning fixture 100 to the detection position. When the fixture body moves the cells to be repaired to the detection position, the detection module 600 detects the broken grid position on the cells to be repaired and converts the broken grid position into a position signal, which is transmitted to the first moving module 200, the second moving module 400, and the third moving module 500. Then, the second moving module 400 and the third moving module 500 jointly drive the repair module 300 according to the position signal, causing the repair module 300 to move to the broken grid position on the cells to be repaired. Next, the repair module 300 is activated to overflow slurry. The first moving module 200, based on a position signal and via the positioning fixture 100, drives the sheet to be repaired along a first direction. The third moving module 500, based on a position signal, drives the repair module 300 along a third direction, allowing the repair module 300 to automatically complete the grid line repair on the sheet. Finally, after the sheet is repaired, the repair module 300 stops overflowing slurry, and the first moving module 200, second moving module 400, and third moving module 500 reset. The positioning fixture 10 resets to the loading position to facilitate the removal of the repaired sheet and the repositioning of the unrepaired sheet. The battery cell grid line repair machine 10 of this application can automatically complete the grid line repair on the sheet, effectively improving the grid line repair efficiency, repair accuracy, and repair quality stability, while reducing the labor intensity of operators.

[0036] It should be noted that the cell to be repaired is a battery cell with defective conductive grid lines. The detection location refers to the position of the positioning fixture 100 when detecting the broken grid location and repairing the grid lines on the cell to be repaired.

[0037] Specifically, in this embodiment, the second direction is set as the direction in which the repair module 300 approaches or moves away from the positioning fixture 100 when the positioning fixture 100 is in the detection position. In other embodiments, the third direction can also be set as the direction in which the repair module 300 approaches or moves away from the positioning fixture 100 when the positioning fixture 100 is in the detection position.

[0038] The first moving module 200, the second moving module 400, and the third moving module 500 can all be configured as any linear moving structure in the prior art. The repair module 300 can be configured as any structure in the prior art for repairing the grid lines of solar cells.

[0039] The detection module 600 can be configured as any existing detection structure capable of detecting and acquiring the location of the broken grid line on the wafer to be repaired. Specifically, in this embodiment, the detection module 600 can be configured as a CCD sensor.

[0040] Can Figure 1 and Figure 2 As shown, optionally, there are two positioning fixtures 100, which are arranged along the first direction and are both connected to the first moving module 200 via a transmission connection. In this way, the two positioning fixtures 100 can move alternately to the detection position; that is, when one of the two positioning fixtures 100 is in the detection position, the other is in the corresponding loading position, reducing the waiting time of the repair module 300 and improving the repair efficiency of the battery cell grid line rework machine 10.

[0041] The instruction manual states that when there are two positioning fixtures 100, there are also two corresponding feeding positions, located on both sides of the detection position along the first direction.

[0042] It should be noted that both positioning fixtures 100 are connected to the first moving module 200 via a transmission. There can be two first moving modules 200, each driving one positioning fixture 100, or there can be one first moving module 200, which simultaneously drives both positioning fixtures 100. The only requirement is that the two positioning fixtures 100 can be moved alternately to the detection position.

[0043] like Figure 2 As shown, in one embodiment, the positioning fixture 100 is provided with a fixing part 110, which is used to fix the piece to be repaired onto the positioning fixture 100. In this way, the fixing part 110 can play a temporary fixing role, ensuring that the piece to be repaired will not move relative to the positioning fixture 100 during the movement and repair process, thereby improving the reliability of the battery cell grid line repair machine 10.

[0044] The fixing part 110 may be provided with fixing holes, fixing blocks, or other fixing structures. The number of fixing parts 110 can be flexibly adjusted according to actual usage needs.

[0045] like Figure 2 As shown, optionally, the fixing part 110 is configured as a vacuum suction hole 111, and the number of vacuum suction holes 111 is at least one, with each vacuum suction hole 111 spaced apart. In this way, each vacuum suction hole 111 is connected to a vacuum pumping device, which evacuates the vacuum suction holes 111 to achieve fixing without damaging the cell to be repaired, thereby improving the reliability of the cell grid line repair machine 10.

[0046] like Figure 2As shown, optionally, the edge of the positioning fixture 100 is provided with positioning ribs 120, which are used to position and cooperate with the piece to be repaired. In this way, the positioning ribs 120 can play a positioning role, so that the piece to be repaired can be quickly and accurately installed on the positioning fixture 100, improving the convenience of the battery cell grid line repair machine 10.

[0047] In this specific embodiment, the shape of the positioning rib 120 is adapted to the edge shape of the piece to be repaired.

[0048] like Figure 2 As shown, optionally, the positioning fixture 100 has grooves 130 on both opposite sides, and the grooves 130 are configured to avoid obstruction during the handling of the sheet to be repaired. In this way, the grooves 130 can avoid the operator's fingers to facilitate the handling of the sheet to be repaired, thereby improving the practicality of the battery cell grid line repair machine 10.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the cell grid rework machine 10 includes a base 700. A first moving module 200 includes a first driving assembly 210 and a first guide member 220. The first driving assembly 210 is pulsatorically connected to the positioning fixture 100. The first guide member 220 is disposed on the base 700 along a first direction and guides the positioning fixture 100. Thus, the first guide member 220 serves a guiding function, ensuring that the positioning fixture 100 can move accurately and reliably along the first direction to the detection position, thereby improving the reliability of the cell grid rework machine 10.

[0050] It should be noted that the first guide member 220 can be directly guided to the positioning fixture 100, or it can be guided to the positioning fixture 100 by means of an intermediate element (such as a slider). In this embodiment, the first guide member 220 is set as a slide rail.

[0051] like Figure 3 and Figure 4 As shown, in one embodiment, the second moving module 400 includes a movable component 410, on which both the detection module 600 and the repair module 300 are mounted. Thus, the detection module 600 and the repair module 300 are integrated on the movable component 410 and move synchronously with it. This allows the detection module 600 to monitor the repair status of the cell to be repaired in real time during the repair process and make feedback adjustments, improving the repair quality and practicality of the cell grid line repair machine 10.

[0052] like Figure 3 and Figure 4As shown, the second moving module 400 further includes a second drive assembly 420 and a second guide member 430. The second drive assembly 420 is connected to the movable member 410 in a driving manner. The second guide member 430 is arranged along a second direction and cooperates with the movable member 410 in a guiding manner. In this way, the second guide member 430 can play a guiding role, ensuring that the repair module 300 can move accurately and reliably along the second direction, thereby improving the reliability of the cell grid line repair machine 10.

[0053] like Figure 3 and Figure 4 Optionally, the cell grid line repair machine 10 also includes a mounting bracket 800. The third moving module 500 further includes a third drive assembly 510 and a third guide member 520. The third drive assembly 510 is drively connected to the second guide member 430. The third guide member 520 is disposed on the mounting bracket 800 along a third direction and is guided and cooperates with the second guide member 430. In this way, the third guide member 520 can play a guiding role, ensuring that the second moving module 400 can accurately and reliably drive the repair module 300 to reciprocate along a third direction, thereby improving the reliability of the cell grid line repair machine 10.

[0054] Specifically, in this embodiment, the mounting frame 800 includes a crossbeam 820 and two support columns 810. The bottoms of the two support columns 810 are respectively fixed to the two sides of the base 700 along the third direction, and the tops of the two support columns 810 are correspondingly fixedly connected to the two ends of the crossbeam 820 to form a portal structure.

[0055] like Figure 1 and Figure 4 As shown, in one embodiment, the repair module 300 includes a slurry storage structure 310, a repair needle 320, and a slurry driving mechanism 330 that is communicatively connected to the detection module 600. The slurry driving mechanism 330 is connected to both the slurry storage structure 310 and the repair needle 320, and is controlled to transport the slurry in the slurry storage structure 310 to the repair needle 320.

[0056] Specifically, in this embodiment, the slurry driving mechanism 330 can be configured as a slurry extrusion driving control cylinder. The cell grid wire repair machine 10 also includes a controller, which is communicatively connected to the slurry driving mechanism 330. The detection module 600 is communicatively connected to the first moving module 200, the second moving module 400, and the third moving module 500 via the controller. The controller can be configured as a microcontroller or a programmable logic controller. The communication connection can be one of the following: data cable, power cable, Bluetooth, or wireless communication network technology.

[0057] Optionally, the cell grid line rework machine 10 includes a first trigger connected in communication with a controller. The first trigger is configured to trigger and generate a first trigger signal when the positioning fixture 100 moves to the detection position. The first trigger signal is fed back to the controller, enabling the controller to control the detection module 600 to work according to the first trigger signal.

[0058] Optionally, the cell grid line repair machine 10 includes a second trigger connected in communication with the controller. The second trigger is configured to trigger and generate a second trigger signal when the positioning fixture 100 moves the cell to be repaired to the detection position and the repair module 300 moves to the broken grid position on the cell to be repaired. The second trigger signal is fed back to the controller, so that the controller can control the repair module 300 to work according to the second trigger signal.

[0059] Both the first trigger and the second trigger can be infrared sensors, proximity switches, or other triggering devices.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.
