Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment for grid-free solar cells, and in particular to a printing adjustment device for grid-free solar cells. Background Technology

[0002] Gridless solar cells typically use solder ribbons to collect current through fine grids and interconnect cells. Because there are no main grids, the solder ribbons cannot make contact with each grid cell for conductivity. This results in poor adhesion between the solder ribbons and the gridless cells, making the cell strings prone to deformation and detachment during subsequent transport, ultimately affecting the efficiency of the solar module. In existing solutions, UV adhesive is typically applied to the original grid locations of the cells during module assembly to ensure a strong connection between the solder ribbons and the cells.

[0003] However, since the solar cells are welded into strings and placed on a welding conveyor belt, which is quite long, the solar cells are prone to misalignment during operation. This can lead to inaccurate positioning during the adhesive printing process, resulting in offset of the adhesive printing points. Utility Model Content

[0052] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0053] 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 the orientation or positional relationship, are based on the orientation or positional relationship 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, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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.

[0055] See Figures 1 to 6This utility model embodiment provides a gridless battery cell printing adhesive adjustment device for placing and adjusting the position of the screen 100 and installing it on the main frame 200 of the equipment.

[0056] Specifically, the gridless solar cell printing and adjustment device includes a first frame 1, a second frame 2, a lifting drive mechanism 3, a vision inspection mechanism 4, a first adjustment mechanism 5, and a second adjustment mechanism 6. The first frame 1 is used to place and fix the stencil 100. The second frame 2 is slidably connected to the first frame 1 along a first horizontal direction and is offset from the first frame 1. The lifting drive mechanism 3 is used to drive the first frame 1 and the second frame 2 to rise and fall. The lifting drive mechanism 3 is slidably connected to the second frame 2 along a second horizontal direction, which is perpendicular to each other. The vision inspection mechanism 4 is used to detect the position of the stencil 100. The first adjustment mechanism 5 is connected between the first frame 1 and the second frame 2 to adjust the relative position of the first frame 1 and the second frame 2 along the first horizontal direction. The second adjustment mechanism 6 is connected between the second frame 2 and the lifting drive mechanism 3 to adjust the relative position of the first frame 1 and the second frame 2 relative to the lifting drive mechanism 3 along the second horizontal direction.

[0057] Through the above scheme, during the adhesive printing process, the position of the battery cell located on the welding conveyor belt can be detected by the vision inspection mechanism 4. The first adjustment mechanism 5 and the second adjustment mechanism 6 can adjust the position of the stencil 100 along the first and second directions according to the detected position of the battery cell, thereby aligning the mesh on the stencil 100 with the adhesive dispensing position on the battery cell and preventing the adhesive dots from shifting. In addition, the first adjustment mechanism 5 adjusts along the first horizontal direction, and the second adjustment mechanism 6 adjusts along the second horizontal direction, with the first and second horizontal directions being perpendicular to each other. The second frame 2 is offset from the first frame 1, so their operation does not interfere with each other, yet they can work together to achieve rapid adjustment of the position of the stencil 100.

[0058] As can be seen, in this embodiment, both the first frame 1 and the second frame 2 are set as rectangles, and the first horizontal direction is parallel to the running direction of the battery cell (see details). Figure 4 (See X11 and X12 directions shown). The second horizontal direction is perpendicular to the running direction of the solar cells (see details). Figure 4 (Y11 and Y12 directions shown).

[0059] See Figures 1 to 3 The lifting drive mechanism 3 includes two lifting drive units 31 symmetrically arranged about the second frame 2, and a linkage drive unit 32 that drives the two lifting drive units 31 to move synchronously. Through the symmetrically arranged lifting drive devices, the mesh plate 100 can be moved stably during the lifting and adjustment process, ensuring the horizontality of the mesh plate 100.

[0060] Specifically, the linkage drive unit 32 includes a driving wheel 321, a driven wheel 322, an adjusting wheel 323, and a synchronous belt 324. The driven wheels 322 are correspondingly arranged one-to-one with the lifting drive unit 31. The synchronous belt 324 is wound around the driving wheel 321, driven wheel 322, and adjusting wheel 323 to drive them to rotate synchronously. The adjusting wheel 323 is used to adjust the shape formed by the synchronous belt 324. It is known that there are two adjusting wheels 323. The two adjusting wheels 323 are parallel to the driven wheel 322 along the tangential direction of the synchronous belt 324, making the portion of the synchronous belt 324 between the driven wheel 322 and the adjusting wheel 323, and the portion between the two driven wheels 322, relatively parallel, thereby increasing the stability of the driven wheel 322.

[0061] Furthermore, the lifting drive unit 31 includes a lifting guide rail 311, a lifting slider 312, a connecting plate 313, a nut lifting block 314, a lifting screw 315, and a screw mounting base 316. The lifting guide rail 311 is fixed to the main frame 200 of the equipment. The lifting slider 312 is slidably mounted on the lifting guide rail 311, specifically along the vertical direction, which is also the direction of the central axis of the lifting screw 315. Two lifting sliders 312 are provided, and the two lifting sliders 312 are symmetrically arranged on both sides of the lifting screw 315. The connecting plate 313 is fixedly connected to both the lifting slider 312 and the nut lifting block 314. The lead screw mounting base 316 is fixedly connected to the main frame 200 of the equipment. The lifting lead screw 315 is rotatably mounted on the lead screw mounting base 316 and is rotatably threadedly connected to the nut lifting block 314. There are two lead screw mounting bases 316, which are rotatably connected to both ends of the lifting lead screw 315 respectively. The nut lifting block 314 is located in the area formed between the two lead screw mounting bases 316 so that the lead screw mounting bases 316 on both sides can limit the nut lifting block 314. One end of the lifting lead screw 315 is fixedly connected to the driven wheel 322.

[0062] It is known that the specific process of driving the screen plate 100 to rise and fall is as follows: the drive wheel 321 is driven to rotate, and the drive wheel 321 drives the driven wheel 322 to rotate through the synchronous belt 324, which in turn drives the lifting screw 315 connected to the driven wheel 322. The lifting screw 315 cooperates with the nut lifting block 314, which in turn drives the connecting plate 313 to rise and fall, and further drives the second frame 2, the first frame 1 and the screen plate 100 to rise and fall.

[0063] See Figure 4The first adjustment mechanism 5 includes a first servo motor 51, a first fixed base 52, a first nut adjustment block 53, and a first adjustment screw 54. The first servo motor 51 and the first fixed base 52 are both fixedly installed on the second frame 2. The first nut adjustment block 53 is fixedly installed on the first frame 1. One end of the first adjustment screw 54 is rotatably installed on the first fixed base 52 and driven by the first servo motor 51 (the first servo motor 51 and the first adjustment screw 54 can be connected by a first coupling 50), and the other end is threadedly connected to the first nut adjustment block 53.

[0064] Correspondingly, the second adjustment mechanism 6 includes a second servo motor 61, a second fixed base 62, a second nut adjustment block 63, and a second adjustment screw 64; the second servo motor 61 and the second fixed base 62 are both fixedly installed on the lifting drive mechanism 3; the second nut adjustment block 63 is fixedly installed on the second frame 2; one end of the second adjustment screw 64 is rotatably installed on the second fixed base 62 and driven by the second servo motor 61 (the second servo motor 61 and the second adjustment screw 64 can be connected by a second coupling 60), and the other end is threadedly connected to the second nut adjustment block 63.

[0065] See Figure 1 The visual inspection unit 4 includes a visual camera 41 and a visual light source 42.

[0066] See Figure 1 In order to protect the wires (such as the wires connecting the motor), a wire routing structure 8 is also included; one end of the wire routing structure 8 is fixedly connected to the main frame 200 of the equipment, and the other end is connected to the lifting drive mechanism 3.

[0067] See Figure 5 and Figure 6 The first frame 1 includes a support plate 11; the upper end of the support plate 11 is provided with a mesh plate pressing mechanism 7, which includes a mounting frame 71, a guide shaft 72, a pressure plate 73 and an elastic pressing member 74; the mounting frame 71 is fixed on the inner wall of the first frame 1, the guide shaft 72 is slidably mounted on the mounting frame 71 and fixedly connected to the pressure plate 73; the pressure plate 73 faces the support plate 11, and the elastic pressing member 74 applies a pushing force toward the support plate 11 to the pressure plate 73.

[0068] To ensure uniform force distribution on the pressure plate 73 and maintain a horizontal end face, the guide shaft 72 includes a central guide shaft 721 and at least two balancing guide shafts 722. The central axis of the central guide shaft 721 passes through the center point of the pressure plate 73 and is perpendicular to the end face of the pressure plate 73. The balancing guide shafts 722 are symmetrically arranged about the central guide shaft 721. Elastic compression members 74 are correspondingly arranged with each balancing guide shaft 722 and are wound around the outside of the balancing guide shafts 722. The elastic compression members 74 are preferably springs; however, in other embodiments, they can also be elastic rubber rings, elastic gaskets, etc.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
