The four sets of sliding assemblies 27 are respectively disposed at the bottom of the first clamping jaw 221, the second clamping jaw 222, the third clamping jaw 223 and the pushing member 25. The sliding assembly 27 includes a slider 271 and a sliding rail 272 disposed corresponding to the slider 271. Four slide rails 272 are disposed on the top wall 2311 of the base 231, and four sliders 271 are respectively disposed on the bottoms of the first clamping jaw 221, the second clamping jaw 222, the third clamping jaw 223 and the pushing member 25, so that the first clamping jaw 221, the second clamping jaw 222, the third clamping jaw 223 and the pushing member 25 can slide on the base 231.

After the products 20 are fixed and loaded on the carrier seat 232 by the clamping assembly 22 and the suction cup assembly 24, the material taking assembly 32 adsorbs the protective film 10 and moves to the upper side of the products 20 by the moving assembly 31. At this time, the connecting assembly 35 drives the material taking assembly 32, the roller assembly 33 and the rotating assembly 34 to rotate to adjust the protective film 10, so that the attaching direction of the protective film 10 is consistent with the direction of the product 20. The third driving member 21 pushes the driving member 211 to move in the clamping space, and the driving member 211 pushes the first clamping jaw 221, the second clamping jaw 222 and the third clamping jaw 223 to separate from the product 20. The first driving member 342 drives one side of the film absorbing member 321 to move upward, so that the film absorbing member 321 tilts and rotates to tilt at a certain angle with the product 20 in the second direction during the process of attaching the protective film 10. The first roller 331 attaches the protective film 10 to the product 20 along the second direction, when the first roller 331 approaches the boss 210 on the product 20, the fourth driving member 334 moves upward and drives the roller bracket 335 to rotate, the positions of the second roller 332 and the first roller 331 are switched, and then the second roller 332 attaches the protective film 10 to the product 20 avoiding the boss 210. In the process of attaching the protective film 10, because the first clamping jaw 221, the second clamping jaw 222 and the third clamping jaw 223 are separated from the product 20, the first roller 331 and the second roller 332 can attach the protective film 10 at the edge of the product 20, so that bubbles are avoided, time is saved, and cost is reduced. After the film pasting is finished, the film pasting mechanism 3 resets to continue to suck the protective film 10, and preparation is made for next film pasting. Meanwhile, the third driving member 21 is reset, and the first clamping jaw 221, the second clamping jaw 222 and the third clamping jaw 223 are restored to the clamping state by the elastic force of the elastic element 26 to clamp the product 20. Namely, the film pasting equipment 100 finishes the film pasting process.

In summary, the following steps: the application discloses a film sticking device 100, wherein a rotating assembly 34 is connected to a moving assembly 31, a material taking assembly 32 and a roller assembly 33 are arranged on the rotating assembly 34, and the material taking assembly 32 is pivoted on the rotating assembly 34 and can rotate along an axis. The material taking assembly 32 is used for taking out the protective film 10 to face the product 20, and when the roller assembly 33 rolls the protective film on the product 20, the rotating assembly 34 drives the material taking assembly 32 to incline so as to attach the protective film 10 on the product 20 in a matching manner, so that bubbles are prevented from being generated in the film attaching process, the production efficiency is improved, and the production cost is reduced.
