The EVA material has the elasticity, limit tension atress unstable, softer reason such as easily placing after drawing the material and present the fold condition at the glass surface because of own characteristic, and the battery cluster is placed and is caused the cluster apart from bad on the EVA of swell when causing the type-setting machine to typeset behind the fold, and personnel contact pulling back probably causes whole square matrix skew, influences on-the-spot production. In order to solve the abnormity, a surface smoothing device is added after the EVA is discharged.

The utility model discloses a concrete embodiment discloses a device is smoothed to EVA fold, include: the device comprises a smoothing roller 1, a bearing 2, a roller shaft 3, a buffer mechanism and a fixing plate 7; the smoothing roller 1 is installed on a roller shaft 3 through a bearing 2, and the smoothing roller 1 can rotate relative to the roller shaft 3; a buffer mechanism is arranged between the roller shaft 3 and the fixing plate 7, and the smoothing device is arranged on the stand columns 8 on two sides of the EVA material processing equipment production line through the fixing plate 7.

The utility model discloses a smooth device smooths the EVA fold at ordinary times: through adjusting the mounting height of smoothing roller 1, make smoothing roller 1 and the EVA material direct contact of glass upper surface, when the synchronous glass of EVA material moved on the assembly line, smoothing roller 1 rolled on the EVA material surface, smoothed the fold on EVA surface through smoothing roller 1.

Specifically, the smoothing roller 1 is of a cylindrical structure, and the smoothing roller 1 is sleeved on the roller shaft 3 through two groups of bearings 2 at two ends.

The utility model discloses a smooth device, smooth roller 1 and install on gyro wheel axle 3 through bearing 2, can take place to roll for the EVA material, make smooth roller 1 when providing the packing force that pushes down (vertical direction) and smooth the fold, minimize the frictional force that produces the (horizontal direction) of side direction, avoid taking place relative displacement between EVA material and the glass board.

Further, two groups of fixing plates 7 and two groups of buffer mechanisms are arranged, two ends of the roller shaft 3 are connected with the buffer devices, and the roller shaft 3 is installed on the upright posts 8 at two sides of the photovoltaic assembly production line through the buffer devices and the fixing plates 7, as shown in fig. 1 and 2.
