Description

Technical Field

[0001] The present invention relates to the field of solar backboard production equipment, and in particular to a cutting device for grid printing equipment of solar backboards. Background Art

[0002] During the production of solar panels, the backsheet requires grid printing. After printing, it needs to be dried in an oven. The existing process involves unwinding the backsheet film from a roll using an unwinder. The film is then trimmed and punched before being fed to a screen printer via rollers. The grid is screen-printed on the screen printer, and after printing, the printed ink is dried in an oven. After the oven is finished, the printed backsheet is reeled up using a winder. Slitting and cutting machines are then used to trim and cut the printed backsheet, slicing the roll to the desired size. This completes the photovoltaic backsheet. However, this method uses a continuous roll. During the roll printing process, the roll can overheat in the oven, creating a risk of scorching. Therefore, a cutting device is urgently needed between the printing equipment and the oven to cut the roll to size before feeding it into the oven, allowing each backsheet to pass independently through the oven.

[0016] A cutting device for a grid printing device for a solar backsheet, such as Figure 1-Figure 5 As shown, it includes a cutting bracket 1, a clamping mechanism 2, a cutting mechanism 3 and two groups of first drive components 4. The cutting bracket 1 is provided with a support part 11 and a hollow part 12. The support part includes an arranged roller 111 and a cutting plate 112. The hollow part allows an opening for the photovoltaic backsheet to pass through; the cutting mechanism 3 and the clamping mechanism 2 are respectively arranged on the cutting bracket 1 through the first drive component 4, and the first drive component 4 is used to control the cutting mechanism 3 and the clamping mechanism 2 to move along the Y axis respectively; the cutting mechanism 3 includes a second drive component 31, a height adjustment component 32 and a cutting machine 33. The cutting machine 33 is arranged on the second drive component 31 through the height adjustment component 32, and the second drive component 31 is used to control the cutting machine 33 to move along the X axis, and the height adjustment component 32 is used to adjust the height position of the cutting machine 33. During operation, the first drive assembly 4 controls the clamping mechanism 2 to move along the Y-axis, clamping the end of the coil. The first drive assembly 4 then controls the movement of the coil. Once the coil reaches the specified length, the cutting mechanism 3 cuts the coil. The cut coil falls from the opening into the feed mechanism of the oven below. The clamping mechanism 2 opens, allowing the coil to completely fall into the feed mechanism, which then feeds the coil into the oven. Another set of first drive assemblies 4 adjusts the position of the cutting mechanism 3 along the Y-axis.

[0017] In one embodiment, if Figure 1-Figure 5 As shown, the first driving assembly 4 includes a first driving wheel 41, a first driven wheel, a connecting rod 43, a first guide rail 44 and a first motor 45. The first guide rail 44 is arranged on both sides of the cutting bracket 1. The first driving wheel 41 and the first driven wheel are respectively arranged on both sides of the cutting bracket 1, and the first driving wheel 41 and the first driven wheel are linked by a first synchronous belt. The two first driving wheels 41 are connected by a connecting rod 43. The first motor 45 drives the first driving wheel 41 to drive the synchronous belt to rotate forward or reverse.

[0018] The connection structure between the first drive assembly 4 and the clamping mechanism 2 is that both ends of the clamping mechanism 2 are slidably connected to the first guide rail 44, and the first guide rail 44 supports and guides the clamping mechanism 2 to move along the Y-axis. In addition, the clamping mechanism 2 is also connected to the synchronous belt. When the first motor 45 drives the first driving wheel 41 to drive the synchronous belt, it provides driving force for the clamping mechanism 2, thereby causing the clamping mechanism 2 to move along the first guide rail 44. The connection structure between the cutting mechanism 3 and the first drive assembly 4 is the same as the above-mentioned connection mechanism. In the above embodiment, the first guide rail 44 of the first drive assembly 4 that respectively controls the clamping mechanism 2 and the cutting mechanism 3 can be shared, which can reduce equipment costs and improve the compactness of the equipment.
