It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0020] refer to Figures 1-3 This embodiment provides a device for blocking the front grid lines of a monocrystalline silicon solar cell string, including: a support plate 1, a tape mounting assembly 2, a front tape guide module 3, and a rear tape guide module 4 arranged sequentially along the length of the support plate 1; the front tape guide module 3 and the rear tape guide module 4 form a placement space for the solar cell string 5.

[0021] It also includes a tape pressing assembly 6 that slides along the length of the support plate 1, for guiding the tape at the front tape guide module 3 to the rear tape guide module 4, and pressing the tape onto the grid lines on the surface of the battery string 5.

[0022] The tape mounting assembly 2 includes a tape fixing seat 21 and a tape guide wheel 22. A tape 23, with the same number of grid lines, is fixed between the two side plates of the tape fixing seat 21. The tape guide wheel 22 is disposed between the tape 23 and the front tape guide module 3. One end of the tape 23 passes around the tape guide wheel 22 and is guided to the front tape guide module 3. To facilitate the rotation of the tape 23 within the tape fixing seat 21, the side plate of the tape fixing seat 21 is provided with an upward-facing U-shaped groove 211. Both ends of the tape 23 extend outward along the axial direction to form a rotating shaft 231 placed in the U-shaped groove 211.

[0023] The tape pressing assembly 6 includes a slider 61, a tape adhesive plate 62, and guide posts 63. The slider 61 is slidably connected to a guide rail 11 on the support plate 1. The two ends of the tape adhesive plate 62 are movably connected to the slider 61 via the guide posts 63, so that the tape adhesive plate 62 has translational freedom in the vertical direction relative to the slider 61. The lower surface of the tape adhesive plate 62 is an adhesive surface. In addition, to facilitate the user in pressing down the tape adhesive plate 62, a handle 64 is provided on the upper surface of the tape adhesive plate 62.

[0024] The front tape guide module 3 and the rear tape guide module 4 are respectively provided with tape guide grooves 31 and 41, which have the same number of grid lines. Furthermore, the front tape guide module 3 includes a tape anti-detachment pressure block 32 that confines the tape 23 within the guide groove.

[0025] The support plate 1 has baffles 12 on both sides of the placement space to fix the position of the battery string 5.

[0026] In use, fix the tape fixing seat 21, the front tape guide module 3, and the rear front tape guide module 3 on the support plate 1, and adjust the relative positions of the front tape guide module 3 and the rear front tape guide module 3 appropriately according to the length and width of the battery string 5.

[0027] Several rolls of tape 23 (the same number as the number of grid lines in the battery string 5) are installed on the tape holder 21. One end of the tape 23 is passed through the front tape guide module 3 by the guide wheel. The spacing between the multiple tapes 23 is limited by the guide groove in the front tape guide module 3. The adhesive side of the tape 23 is facing down.

[0028] Place the battery string 5 on the tray, which has a limiting edge 12 to fix the position of the battery string 5;

[0029] Press down the tape sticking plate 62 so that multiple tapes 23 are simultaneously adhered to the tape sticking plate 62. At this time, the relative positions of each tape 23 remain unchanged. Slide the tape sticking plate 62 along the guide rail 11 to pull the tape 23 to the rear tape guide module 4. Gently press down the tape sticking plate 62 so that the tape 23 covers the grid lines on the surface of the battery string 5.

[0030] Use scissors to cut the tape 23 at the end of the battery string 5, remove the remaining tape 23 on the tape adhesive plate 62, and pull the tape adhesive plate 62 in the opposite direction through the guide rail 11 so that the tape adhesive plate 62 returns to the front tape guide module 3. Press down gently, and then cut the tape 23 at the front end of the battery string 5 to complete one cycle.
