The third removal mechanism 33 also sucks and removes the tear film strip and attaches it to the inside wall of the back plate.

Referring to fig. 6 and 7, the first adsorption plate 31 is horizontally disposed, and has a row of suction holes 35 on an upper surface thereof arranged along a straight path for adsorbing the lamp bars 60 on the first adsorption plate 31. The first adsorption plate 31 is provided with three strip-shaped holes 36, the three strip-shaped holes 36 being arranged at intervals in the direction along which the straight path extends, and each strip-shaped hole 36 extending across the straight path and to both sides of the straight path. The bottom of the first adsorption plate 31 is provided with a pair of clamping blocks 38 located at both sides of the straight path, respectively, and the pair of clamping blocks 38 are configured to be able to be moved closer to and farther away from each other in synchronization. For example, the pair of clamping blocks 38 are mounted on two of the flat clamping fingers 39, for example, the flat clamping fingers 39 may be HDF series flat clamping fingers 39 of the AirTAC brand. The pair of clamping blocks 38 are provided with three pairs of clamping bars 310 which are arranged at intervals along the direction of the straight path and respectively correspond to the three strip-shaped holes 36, wherein each pair of clamping bars 310 is respectively arranged on two clamping blocks 38. The clamping bars 310 pass through the corresponding bar-shaped holes 36 from bottom to top and protrude from the upper surface of the first adsorption plate 31. The fourth moving mechanism 320 sucks the light bar from the third material table 34, translates over the first suction plate 31, and releases it between the clamping bars 310 with the release film facing downward. The light bar is attracted to the first suction plate 31 and then the flat clamping fingers 39 act to bring the clamping bars 310 closer to each other, thereby adjusting the direction of the light bar.

Since the end of the release film is clamped by the fixed jaw 314 and the movable jaw 315 and the release film is adsorbed on the first adsorption plate 31, the release film is peeled off from the light bar when the third transfer mechanism 33 transfers the light bar. When the LED light bar is completely separated from the release film, the rotary cylinder 316 rotates by an angle to take the release film away from the first adsorption plate 31, and then the fixed jaw and the movable jaw are separated to release the release film.
