The using process of the invention is as follows:
① before the operation, the stacked hot melt adhesive sheets are placed in the hot melt adhesive sheet containing box 4, the heel is covered on the outer surface of the lower U-shaped structure, and the heel is firmly fixed on the lower U-shaped structure due to the negative pressure adsorption of the adsorption plate 34.
② when the work starts, the first driving mechanism drives the first carriage 20 to slide along the first horizontal sliding rail 71 to the vicinity of the hot melt film accommodating box 4, and then the second driving mechanism drives the second carriage 21 to slide along the second horizontal sliding rail 72, so that the hot melt film picking and transferring unit 2 is located right above the hot melt film accommodating box 4, then the output rod of the first linear motion cylinder 22 is controlled to move downwards for a certain stroke, the second linear motion cylinder 23 and the negative pressure type rubber adsorption plate 25 are driven to descend together, when the negative pressure type rubber adsorption plate 25 extends into the hot melt film accommodating box 4 and contacts the hot melt film therein, the negative pressure type rubber adsorption plate 25 is controlled to suck the hot melt film, and then the output rod of the first linear motion cylinder 22 is controlled to contract, and the adsorption plate 25 with the hot melt film is controlled to move upwards to be far away from the accommodating box 4, so as to finish the picking of the hot melt film.
③ then, the first driving mechanism drives the first carriage 20 to slide along the first horizontal sliding rail 71, the second driving mechanism drives the second carriage 21 to slide along the second horizontal sliding rail 72, so that the adsorption plate 25 with the hot melt film absorbed on the lower bottom surface slides over the glue nozzle 5 and the heating nozzle 6, and the glue spraying and heating of the hot melt film are completed, thereby facilitating the deformation and adhesion of the hot melt film in the subsequent process.
④ then the first driving mechanism drives the first carriage 20 to slide along the first horizontal sliding rail 71 to move the hot melt film pick-up and transfer unit 2 to the vicinity of the adhering unit 3, the second driving mechanism drives the second carriage 21 to slide along the second horizontal sliding rail 72 to position the whole hot melt film pick-up and transfer unit 2 right above the adhering unit 3, the output rod of the first linear motion cylinder 22 is controlled to extend downwards to bring the adsorption plate 25 with the hot melt film to move downwards until the hot melt film contacts with the heel of the outer surface of the adsorption plate 34, and then the output rod of the second linear motion cylinder 23 is controlled to contract, at this time, the lower periphery of the guide frame 26 abuts against the center of the top surface of the adsorption plate 25, the two connecting rods 24 pull the two ends of the adsorption plate 25 to approach the guide frame 26, so that the hot melt film deforms along with the adsorption plate 25 to form an upper U-shaped structure.
⑤, controlling the output rod of the first linear motion cylinder 22 to extend downwards continuously, the adsorption plate 25 with the upper U-shaped structure moving downwards against the adsorption plate 34 with the lower U-shaped structure, in the descending process, the adsorption plate 34 changes from the structure of "lower U-shaped structure-straight structure-upper U-shaped structure", so that the hot melt film on the adsorption plate 25 finally clings to the heel of the shoe on the adsorption plate 34, specifically, in the process of "lower U-shaped structure-straight structure", the adsorption plate 25 moves downwards against the top center of the adsorption plate 34, the push rod 33 slides downwards along the inner cavity of the upright post 32 under the downward force, the upper arch part of the adsorption plate 34 with the lower U-shaped structure rebounds, the two side walls expand outwards, driving the two sliders 31 to move backwards along the guide rod 30, so that the opening of the adsorption plate 34 with the lower U-shaped structure gradually increases, the adsorption plate 34 gradually tends to be straight, and when the two sliders 31 move backwards to the limit position, the adsorption plate 34 returns to the straight state;
in the process of 'straight structure-upper U-shaped structure', the adsorption plate 25 with the U-shaped structure continuously supports against the center of the top surface of the adsorption plate 34 to move downwards, the adsorption plate 34 gradually sinks downwards, two ends of the adsorption plate 34 gradually draw close to two sides of the adsorption plate 25 to drive the two sliders 31 to move in opposite directions along the guide rod 30, the heel on the upper surface of the adsorption plate 34 is gradually attached to the hot melt adhesive film on the adsorption plate 25 from the bottommost part to two sides of the adsorption plate 25 with the U-shaped structure, wrinkles caused by uneven attachment of the heel and the hot melt adhesive film are effectively avoided, when the two sliders 31 move in opposite directions to limit positions, the adsorption plate 34 deforms to form the U-shaped structure, and is completely sleeved on the outer surface of the adsorption plate 25 with the U-shaped structure, and therefore complete attachment of the hot melt adhesive film and the heel is achieved. Then, the adsorption plate 34 is controlled to release the heel, the output rod of the first linear motion cylinder 22 is controlled to contract upwards to drive the adsorption plate 25 to move upwards, in the process that the adsorption plate 25 moves upwards and gradually leaves away from the adsorption plate 34, the first spring 35 in the upright post 32 rebounds to push the ejector rod 33 to move upwards, the ejector rod 33 pushes the bottom center of the adsorption plate 34 to move upwards, the adsorption plate 34 is made to return to the original lower U-shaped structure, then, the adsorption plate 25 is controlled to release the hot melt film, the heel adhered with the hot melt film is manually transferred, the output rod of the second linear motion cylinder 23 is controlled to extend downwards, the adsorption plate 25 is made to return to the original straight state, and preparation is made for picking up the next hot melt film.
