Description

Technical Field

[0001] This utility model relates to the field of photovoltaic production technology, and in particular to a photovoltaic irregular-shaped welding strip node position adjustment device. Background Technology

[0002] With the continuous development of solar cell and module technology, new module processes are constantly emerging. In current stringing processes, circular solder strips are typically used to connect the front and back sides of two adjacent cells. To improve the light reception of the front side of the cell, the solder strip is designed as a triangle. To reduce the welding difficulty and reliability of the solder strip on the back side of the cell, it is designed as a flat shape. In addition, flat solder strips are also used to connect adjacent cells, thus forming irregularly shaped solder strips with continuous intervals between triangular and flat segments.

[0003] However, in actual production, due to differences in the solder ribbon material and the cumulative error during the cutting process, the solder ribbon nodes (the transition point between the triangular and flat ribbons) can shift. In severe cases, the triangular solder ribbon may shift to the back of the solar cell, resulting in defective strings. Traditional production of irregularly shaped solder ribbons for solar cells typically involves 9BB-12BB. When more BB numbers are involved, such as 20BB or more grid lines, the existing structural methods cannot meet production requirements. Utility Model Content

They 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. Therefore, they should not be construed as limitations on this utility model.

[0047] As a specific embodiment of this utility model, such as Figure 1As shown, this utility model provides a photovoltaic irregularly shaped welding strip node position adjustment device, which may include: a frame 100, a clamping mechanism 200, a first driving mechanism 300, and a second driving mechanism 400. The clamping mechanism 200 is movably mounted on the frame 100 along a first direction and is used to clamp the irregularly shaped welding strip along the first direction. The first driving mechanism 300 is mounted on the frame 100 to drive the clamping mechanism 200 to loosen or tighten. The second driving mechanism 400 is mounted on the frame 100 and connected to the clamping mechanism 200, and drives the clamping mechanism 200 to move along the first direction.

[0048] Specifically, in this embodiment of the photovoltaic irregular-shaped solder ribbon node position adjustment device, a first driving mechanism 300 is provided on the frame 100 to drive the clamping mechanism 200 to loosen or tighten, and a second driving mechanism 400 is provided on the frame 100 to connect to the clamping mechanism 200 and drive the clamping mechanism 200 to move along a first direction, wherein the first direction is the transfer direction of the solder ribbon. In other words, by adjusting the position of the clamping mechanism 200 in the transfer direction, the node position of the solder ribbon during the transfer process can be effectively and accurately adjusted, thereby meeting production requirements.

[0049] In some embodiments, such as Figure 1 As shown, the frame 100 may include a base plate 110 and a pair of upright plates 120. The pair of upright plates 120 are disposed on the base plate 110 at a distance from each other, a pressing mechanism 200 is movably disposed between the pair of upright plates 120, and a first driving mechanism 300 is disposed above the pair of upright plates 120.

[0050] That is, a clamping mechanism 200 is provided between a pair of upright plates 120 on the substrate 110. The clamping mechanism 200 can move between the pair of upright plates 120 (i.e., in the first direction), and a first driving mechanism 300 is provided above the pair of upright plates 120 to control the clamping mechanism 200 to loosen or tighten.

[0051] In some embodiments, such as Figure 2 and Figure 3As shown, the clamping mechanism 200 may include at least one clamping component 210 disposed along a second direction, wherein the first direction is perpendicular to the second direction. As an example, the clamping component 210 may be disposed along the length of the upright plate 120. The clamping component 210 may include a pressure head seat 211 and a pressure head 212. The pressure head seat 211 is movably disposed between a pair of upright plates 120 along the first direction. One end of the pressure head 212 is pivotally connected to one side of the top surface of the pressure head seat 211, and the other end of the pressure head 212 is pressed against the other side of the top surface of the pressure head seat 211 by a spring 213. A first driving mechanism 300 extends to drive the other end of the pressure head 212 downwards, causing one end of the pressure head 212 to open relative to the top surface of the pressure head seat 211; the first driving mechanism 300 retracts, and the other end of the pressure head 212 returns to its original position under the action of the spring 213, causing one end of the pressure head 212 to close relative to the top surface of the pressure head seat 211.

[0052] In other words, one or more clamping assemblies 210 are arranged along the length of a pair of upright plates 120 to clamp the welding strips for various production quantity requirements. The clamping assembly 210 includes a pressure head seat 211 and a pressure head 212 pivotally connected to the pressure head seat 211. The driving end of the pressure head 212 is connected to the surface of the pressure head seat 211 through a spring 213. The driving end of the pressure head 212 swings under the cooperative action of the first driving mechanism 300 and the spring 213, thereby controlling the other end of the pressure head 212 relative to its driving end to achieve the action of clamping or loosening with the corresponding part of the pressure head seat 211.

[0053] In some embodiments, the top end of the pressure head seat 211 has an extension 2111 formed along a first direction. A rotating shaft (not shown) along a second direction is passed through the extension 2111, and one end of the pressure head 212 passes through the rotating shaft so that the pressure head 212 can rotate in the vertical plane where the first direction is located.

[0054] As an example, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the top of the pressure head seat 211 has an extension 2111 formed along the first direction. The extension 2111 has a rotating shaft mounting hole 2112 extending along the second direction. The rotating shaft mounting hole 2112 is used to mount the rotating shaft. One end of the pressure head 212 has a rotating shaft hole 2123, through which the pressure head 212 is passed onto the rotating shaft, thereby allowing the pressure head 212 to swing around the rotating shaft. In addition, the upper surface of the end of the pressure head 212 away from the rotating shaft hole 2123 is a driving surface 2122. The bottom of the driving surface 2122 is connected to the pressure head seat 211 by a spring 213. Thus, the first driving mechanism 300 realizes the rotation of the pressure head 212 by pressing the driving surface 2122. When the first driving mechanism 300 returns to its original position, the driving surface 2122 is reset under the action of the spring 213.

[0055] In some embodiments, such as Figure 3 As shown, a pressure cap 2113 is also connected to the corresponding rotating shaft on the extension 2111.

[0056] Specifically, the pressure cap 2113 is locked at the front end of the extension 2111 of the pressure head seat 211 to limit the axial movement of the rotating shaft within the rotating shaft mounting hole 2112.

[0057] In some embodiments, such as Figure 4 As shown, a limiting groove 2114 extending in the first direction is also formed on the top surface of the pressure head seat 211.

[0058] Specifically, a limiting groove 2114 extending along the first direction (i.e. the transfer direction of the welding strip) is opened on the top surface of the pressure head seat 211. When the pressure head 212 and the pressure head seat 211 work together to achieve pressing, the welding strip is limited in the limiting groove 2114 to prevent it from shifting during transfer.

[0059] In some embodiments, such as Figure 6 As shown, a plurality of strip grooves 2121 extending in the second direction are formed on the end face of the pressure head 212 relative to the top surface of the pressure head seat 211.

[0060] In other words, multiple strip grooves 2121 are spaced apart on the corresponding pressing surface of the pressure head 212 to form a textured surface structure. This structure works in conjunction with the limiting groove 2114 to further prevent the welding strip from slipping during the adjustment process and losing positional accuracy when clamping it.

[0061] In some embodiments, such as Figure 1 and Figure 3 As shown, the second drive mechanism 400 may include a guide rod motor 410 and a guide shaft 420. The guide rod motor 410 is mounted on the outside of a vertical plate 120, and the guide rod of the guide rod motor 410 passes through the vertical plate 120 from the outside to the inside and connects to the pressure head seat 211 to drive the pressure head seat 211 and the pressure head 212 to move along a first direction. The guide shaft 420 is connected between a pair of vertical plates 120 along the first direction, and the pressure head seat 211 is slidably connected to the guide shaft 420.

[0062] Specifically, the second drive mechanism 400 may include one or more guide rod motors 410 and a guide shaft 420. The guide shaft 420 is used to limit the movement of the pressure head seat 211 and the pressure head 212 between a pair of upright plates 120. The guide rod motor 410 is mounted on one of the upright plates 120 corresponding to the pressure head seat 211, and its guide rod passes through the upright plate 120 to connect to the pressure head seat 211, thereby driving the pressure head seat 211 to move between the pair of upright plates 120, thereby adjusting the node position of the welding strip pressed by the pressure head seat 211 and the pressure head 212. The guide rod motor 410 is connected to the pressure head seat 211 through a guide rod adapter sleeve 430. That is to say, by driving the pressure head seat 211 and the pressure head 212 to move by the guide rod motor 410, the node position of the welding strip can be effectively and accurately adjusted.

[0063] In addition, a motor pressure plate 440 is connected to the upright plate 120 on which the guide rod motor 410 is installed, and the guide rod motor 410 is limited between the upright plate 120 and the motor pressure plate 440 by the motor pressure plate 440.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the frame 100 may further include at least one cylinder fixing plate 130, which is disposed above a pair of upright plates 120. The first drive mechanism 300 may include at least one drive cylinder 310, which is disposed on the cylinder fixing plate 130, and the drive rod of the drive cylinder 310 passes downward through the cylinder fixing plate 130 and abuts against the other end of the pressure head 212.

[0065] Specifically, each end of a pair of upright plates 120 is connected to an adapter seat 140. An adapter block 160 is pivotally connected to the adapter seat 140. The adapter block 160 can rotate along the vertical plane containing the length of the upright plate. One end of each adapter seat 140 is pivotally connected to the adapter seat 140, and the other end of each adapter seat 140 is detachably connected to a cylinder fixing plate 130. The cylinder fixing plate 130 is positioned above the corresponding pressing mechanism 200. One or more drive cylinders 310 are mounted on the cylinder fixing plate 130. The drive rod of the drive cylinder 310 passes downward through the cylinder fixing plate 130 to abut against the drive surface 2122 of the pressure head 212, thereby driving the pressing mechanism 200 to press or release.

[0066] In some embodiments, such as Figure 1 and Figure 2As shown, the cylinder fixing plate 130 may include two pieces, which are arranged vertically on a pair of upright plates 120. The drive cylinder 310 may include multiple pieces, which are spaced apart along the second direction on the upper and lower cylinder fixing plates 130. The drive rod of the upper drive cylinder 310 passes through the upper and lower cylinder fixing plates 130 in sequence and abuts against the other end of the pressure head 212. The drive rod of the lower drive cylinder 310 passes through the lower cylinder fixing plate 130 and abuts against the other end of the pressure head 212.

[0067] Specifically, a connecting block 150 can be connected to the free end of the adapter block 160. Two cylinder fixing plates 130 are connected to the upper and lower ends of the connecting block 150, respectively. Multiple drive cylinders 310 are installed at intervals along the length of each of the two cylinder fixing plates 130. The drive rod of the upper drive cylinder 310 passes sequentially through the gap between the upper and lower drive cylinders 310 and the lower cylinder fixing plate 130, abutting against the drive surface 2122 of the pressure head 212. The drive rod of the lower drive cylinder 310 passes downwards through the lower cylinder fixing plate 130 and abuts against the drive surface 2122 of the pressure head 212. This allows for processing of a large number of welding strips, effectively improving production efficiency.

[0068] In some embodiments, the adapter block 160 may also be pinned to the adapter seat 140, thereby enabling the entire component above the clamping mechanism 200 to be rotated open about one end for easy disassembly and maintenance.

[0069] It should be noted that the photovoltaic irregular welding strip node position adjustment device of this utility model embodiment has a compact structure and can be applied to the production needs of modules with 20BB or more grid lines.

[0070] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
