Description

Technical Field

Although the solar cells have been pre-sorted and arranged, they are still susceptible to displacement due to collisions or thermal expansion of the solder during the welding process. These uncontrollable factors can cause the solar cells to become skewed and deviate from their pre-sorted arrangement, which will affect the welding effect and the product quality of the photovoltaic modules.

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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

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.

[0064] See Figure 1As shown, this application provides a photovoltaic welding device, which includes a device substrate 1000, a transfer component 2000, a positioning component 3000, and a welding component 4000. The device substrate 1000 has a welding station. The transfer component 2000 is assembled on the device substrate 1000 and is configured to transfer a plurality of solar cells to be welded. The positioning component 3000 is assembled on the device substrate 1000 and is configured to position and contact the plurality of solar cells to be welded at the welding station of the device substrate 1000. The welding component 4000 is assembled on the device substrate 1000 and can be a heat pipe welding machine or the like, and can be configured to weld a plurality of solar cells at the welding station of the device substrate 1000.

[0065] Therefore, several battery cells can first be positioned according to a predetermined distribution pattern, i.e., arranged in the shape of a battery array. Then, the several battery cells to be welded are transferred to the welding station of the device substrate 1000 by the transfer component 2000, maintaining the predetermined distribution pattern at the welding station. At this time, the positioning component 3000 can position the several battery cells to be welded, so that the several battery cells maintain the predetermined distribution pattern at the welding station of the device substrate 1000.

[0066] Therefore, when the welding assembly 4000 welds several battery cells, even if the battery cells are impacted during the welding process, causing them to shift in position, or if they shift in position due to the thermal expansion of the solder during the welding process, or if many other uncontrollable factors occur, the positioning assembly 3000 controls the several battery cells to maintain the above-mentioned predetermined distribution at the welding station. Therefore, the battery cells will not become skewed during the welding process, ensuring that the several battery cells can be welded based on the above-mentioned predetermined distribution to form the expected battery array.

[0067] Continue reading Figures 2 to 6 As shown, regarding the positioning component 3000 for the photovoltaic welding device mentioned above, the positioning component 3000 may include a positioning frame 3100, a positioning frame 3200, and a driving device 3300. The positioning frame 3100 is configured as a ring frame, and the inner circle of the positioning frame 3100 forms a space within the frame. For example, the positioning frame 3100 is configured as a square frame, and the space within the frame is configured as a square space. In addition, the positioning frame 3100 may also be configured as a circular frame, an elliptical frame, or other regular or irregular shapes, which are not limited here.

[0068] Continue reading Figures 2 to 4As shown, the internal space of the positioning frame 3100 is divided into several welding space areas and several non-welding space areas. The division of these welding space areas and non-welding space areas is virtual. The purpose of dividing the internal space into several welding space areas and several non-welding space areas is to define the distribution or setting position of the positioning frame 3200 in the internal space. That is, the positioning frame 3200 is connected to the positioning frame 3100. The positioning frame 3200 is located in the internal space of the inner ring of the positioning frame 3100, and the positioning frame 3200 only occupies the non-welding space area in the internal space, but does not occupy the welding space area in the internal space. Thus, the several welding space areas and several non-welding space areas divided in the internal space can be used as the standard for setting the position of the positioning frame 3200 in the internal space of the inner ring of the positioning frame 3100. When there is one or more positioning frames 3200, the space inside the frame can also be divided into a corresponding number of non-welding space areas, so that each non-welding space area is equipped with a positioning frame 3200.

[0069] The positioning frame 3200 can be configured as a rod-shaped frame, with its two ends connected to two different positions of the positioning frame 3100. The rod-shaped frame can be a straight rod, a curved rod, etc. A number of positioning frames 3200 are configured, arranged parallel to each other within the frame space of the positioning frame 3100. Each positioning frame 3200 is provided with a number of positioning elements 3210, which are linearly arranged on the positioning frame 3200. The positioning elements 3210 are configured to position the contact cells.

[0070] The spacing between adjacent positioning elements 3210 on the positioning frame 3200 can be designed to be the same or partially different. Positioning elements 3210 may be provided with flexible portions 3220, such as rubber pads, sponges, or other materials that can buffer contact with the battery cells. This flexible portion 3220 is configured to position and contact the battery cells, mitigating accidental damage caused by force contact. For example, when several positioning elements 3210 contact the battery cells from above and downwards, the bottom of the positioning element 3210 can be configured to position and contact the battery cells, with the flexible portion 3220 located at the bottom of the positioning element 3210.

[0071] Therefore, by means of a large number of positioning elements 3210 on one or more positioning frames 3200, a distribution pattern corresponding to several battery cells can be formed within the space of the frame, so that each positioning element 3210 can form a positional correspondence with one of the several battery cells. The driving device 3300 is drivenly connected to the positioning frame 3100, and the driving device 3300 is configured to drive the positioning frame 3100 to reciprocate along a linear motion trajectory.

[0072] In one embodiment, the linear motion trajectory is configured as a straight line, perpendicular to the plane containing the positioning frame 3100. Alternatively, the linear motion trajectory can be configured as a curved trajectory of a desired shape. Those skilled in the art can design the specific shape of the curved trajectory according to actual needs, thereby achieving predictable control of the positioning frame 3100; no limitation is made here. The welding station of the device base 1000 has a worktable surface. The plane containing the positioning frame 3100 of the positioning component 3000 is parallel to the worktable surface of the welding station of the device base 1000. The linear motion trajectory is configured as a straight line, perpendicular to the worktable surface of the welding station.

[0073] When the several battery cells to be welded are transferred to the welding station of the device substrate 1000, and the predetermined distribution pattern is maintained at the welding station, the driving device 3300 can control the positioning frame 3100 to move along a linear motion trajectory, and control the several positioning elements 3210 to gradually approach the several battery cells, and then use the several positioning elements 3210 to make one-to-one positioning contact with the several battery cells, thereby making the several battery cells maintain the predetermined distribution pattern at the welding station.

[0074] Since several non-welding spaces within the frame have been used to set up the positioning frame 3200, corresponding to several battery cells, but the several welding spaces within the frame are not occupied but are in an unobstructed, open state, the welding assembly 4000 can contact the several battery cells through the several non-welding spaces to perform welding on the several battery cells. Since the positioning assembly 3000 controls the several battery cells to maintain the above-mentioned predetermined distribution at the welding station, the battery cells will not be skewed during the welding process, ensuring that the several battery cells can be welded based on the above-mentioned predetermined distribution to form the expected battery array.

[0075] Continue reading Figure 5 and Figure 6 As shown, in one embodiment, the driving device 3300 may include a device base 3310, an adapter bracket 3320, and a driving source 3330. The adapter bracket 3320 is movably mounted on the device base 3310 and is connected to the positioning frame 3100. Based on the mounting position of the driving device 3300 on the photovoltaic welding device and its mounting relationship with the positioning frame 3100, the adapter bracket 3320 can be configured to have any shape, which is not limited here. The driving source 3330 is mounted on the device base 3310 and connected to the adapter bracket 3320. It is configured to drive the adapter bracket 3320 to move, and the adapter bracket 3320 is configured to drive the positioning frame 3100 to reciprocate along a linear motion trajectory.

[0076] Continue reading Figure 5and Figure 6 As shown, in one embodiment, the driving device 3300 may further include a linear guide rail 3340, which is mounted on the device base 3310 and parallel to the linear motion trajectory. The adapter bracket 3320 is movably mounted on the device base 3310 along the linear guide rail 3340. The guide rail in the driving device 3300 serves as a guide for the movement of the adapter bracket 3320, ensuring that the adapter bracket 3320 can reciprocate precisely along the linear motion trajectory. This, in turn, ensures that the positioning elements 3210 and the battery cells can achieve precise positioning contact, guaranteeing the positioning effect.

[0077] The drive source 3330 may include a drive motor 3331, which is mounted on the device base 3310. A threaded rod 3332 is provided at the output end of the drive motor 3331. The linear motion trajectory is configured as a straight line, with the threaded rod 3332 and the linear motion trajectory parallel to each other. A threaded fitting 3333 is threaded onto the threaded rod 3332, and the threaded fitting 3333 is connected to the adapter bracket 3320. In this configuration, the threaded rod 3332 and the threaded fitting 3333 can be combined to form a lead screw mechanism. When the drive motor 3331 rotates, it drives the threaded rod 3332 to rotate along a fixed axis, converting the fixed-axis rotation of the threaded rod 3332 into linear motion of the threaded fitting 3333. This linear motion is used to drive the adapter bracket 3320 to precisely reciprocate along the linear motion trajectory.

[0078] Continue reading Figure 1 As shown, in one embodiment, the positioning component 3000 may further include a linear guide rail 3400 and a guide motion element 3500. The linear guide rail 3400 and the linear motion trajectory are parallel to each other. The guide motion element 3500 is movably mounted on the linear guide rail 3400 and is directly or indirectly connected to the positioning frame 3100. Therefore, the defined guide rail can simultaneously guide the reciprocating motion of the positioning frame 3100. When the adapter bracket 3320 moves along the direction of the linear motion trajectory, the adapter bracket 3320 can drive the positioning frame 3100 to move along the linear motion trajectory. At this time, the defined guide rail guides the reciprocating motion of the positioning frame 3100, ensuring that the positioning frame 3100 reciprocates accurately along the linear motion trajectory.

[0079] Continue reading Figure 1 As shown, in one embodiment, the transfer assembly 2000 may include a conveyor belt 2100 and a drive wheel set, the drive wheel set including a driving wheel and a driven wheel, the drive wheel set being driven to the conveyor belt 2100 and configured to drive the conveyor belt 2100 to rotate, such that the rotation of the conveyor belt 2100 can pass through the welding station of the device base 1000, and then transfer a number of battery cells at the welding station.

[0080] Continue reading Figures 7 to 9 As shown, in one embodiment, the photovoltaic welding apparatus may further include a flow control component 5000, which is mounted on the apparatus base 1000 and configured to guide the fumes generated during welding of several solar cells. The flow control component 5000 may include a fixing frame 5100, a suction hood 5200, a purification shell 5300, a delivery pipe 5400, a filter plate 5500, a fan 5600, and a filter screen 570, etc. The fixing frame 5100 is used to mount the suction hood 5200 and the purification shell 5300 on the apparatus base 1000. The inner cavity of the suction hood 5200 is provided with a filter screen 570. The filter plate 5500 and the fan 5600 can be mounted in the inner cavity of the purification shell 5300 via a mounting bracket, etc. The suction hood 5200 may be provided with a guide slope, and the filter plate 5500 may be configured as an activated carbon filter element. The filter 570 can filter dust particles in the flue gas, the mounting bracket can increase the stability of the fan 5600, and the guide slope can increase the suction range of the suction hood 5200.

[0081] 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.

[0082] The embodiments described above are merely illustrative of 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.
