[0028] Embodiment one:
[0029] Please refer to Figures 1-4 and Figure 8The utility model discloses a kind of film applicators, for positioning product 100 and in the screen 101 of product 100 Paste protective film, including pedestal 10, pedestal 10 is provided with the positioning platform 11 for supporting product, positioning platform 11 is equipped with the avoidance space 12 for avoiding the protruding portion of product 100, the positioning boss 13 for abutting the one end of product 100 is fixedly arranged in one end of pedestal 10, the other end of pedestal 10 is slidably provided with the sliding boss 14 for abutting the other end of product 100, the clamping structure 18 for positioning product is slidably provided in the both sides of positioning platform 11, clamping structure 18 includes two sliding plates 181 slidably arranged on pedestal 10, each sliding plate 181 is convex with the clamping arm 182 for clamping product and the first spring 184 connecting two sliding plates 181, sliding boss 14 is protruding with drive arm 141 towards positioning boss 13, the both sides of the end of drive arm 141 are outwardly inclinedly provided with drive surface 1411, two drive surfaces 1411 are outwardly expanded and arranged in horn shape, sliding plate 181 is matched with drive surface 1411 to realize that two sliding plates 181 are synchronously relatively outwardly away or inwardly close, and when two sliding plates 181 are synchronously inwardly close, then it needs to be assisted by the restoring force of first spring 184, the first positioning structure 15 for positioning one end of protective film is equipped on positioning boss 13, the second positioning structure for positioning the other end of protective film is equipped on sliding boss 14.
[0030] Further, each sliding plate 181 is convex with abutting column 183, and the abutting column 183 is arranged in abutment with the drive surface 1411. In the embodiment, when the sliding boss 14 is farthest from the positioning boss 13, the two abutting columns 183 abut against the widest position of the horizontal distance of the drive arm 141. At this time, the first spring 184 is stretched, and the two clamping arms 182 are also at the farthest distance, facilitating the placement of products 100 of different width sizes. When the sliding boss 14 is moved towards the positioning boss 13, the two abutting columns 183 slide along the drive surface 1411, and the two clamping arms 182 are synchronously relatively inwardly close under the action of the restoring force of the first spring 184 until the product 100 is clamped, thereby completing the positioning of the product 100 in one direction.
[0031] When it is necessary to paste the protective film, the product 100 is placed on the positioning platform 11, and one end of the product 100 abuts against the positioning boss 13. The sliding boss 14 is controlled to move towards the positioning boss 13 until the product 100 is clamped between the two clamping arms 182 and the other end of the product 100 abuts against the sliding boss 14. The product 100 completes the positioning in the other direction. Then, one end of the protective film is positioned on the first positioning structure 15, and the other end of the protective film is positioned on the second positioning structure. The protective film is pressed downward from one end to the other end, and the tempered film of the protective film is correspondingly pasted on the screen 101 of the product 100.
