[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-3 The semi-automatic film sticking equipment of the present invention is used to stick a protective film to the arc-shaped upper surface of a product, comprising: a lower frame 1 and a rotating platform 3, a mold supply mechanism 4, a film sticking mechanism 5 and a pressure holding mechanism arranged on a working table 2 of the lower frame; a plurality of turntable jigs 6 for placing products are evenly distributed along the same circumference on the rotating platform, and the rotating platform is used to rotate and drive the turntable jig to pass through the film supply mechanism, the film sticking mechanism and the pressure holding mechanism in sequence; specifically, the film supply mechanism is used to provide a protective film attached to the surface of the product; The film-sticking mechanism is used to stick the protective film to the upper surface of the product; the pressure-holding mechanism is used to flatten and fit the protective film attached to the upper surface of the product. Specifically, the pressure-holding mechanism includes: pressure-holding mechanisms 7 at both ends of the short side, pressure-holding mechanisms 8 at both ends of the long side, outer arc surface pressure-holding mechanism 9 and inner arc surface pressure-holding mechanism 10. The above four groups of pressure-holding mechanisms flatten the short side, long side, outer arc surface and inner arc surface of the protective film to fit them to the product respectively. Compared with manually sticking the protective film to the product, the equipment has high attachment accuracy, reduces labor costs and improves production efficiency.

[0033] For further information, see Figure 4-5 The film supply mechanism 4 includes a film supply fixing plate 41 arranged on the lower frame, a material roll 42 arranged on the film supply fixing plate, a film taking station 43, a first feeding roller 44 arranged below the film taking station, a driving shaft 45, a second feeding roller 46 and a waste film collecting wheel 47. The driving shaft is connected to the power output shaft of the first servo motor through a belt. The first servo motor is arranged below the driving shaft (not shown in the figure). A film supply lifting cylinder 48 is also arranged directly below the driving shaft, and a clamping wheel 49 is arranged on the power output shaft of the film supply lifting cylinder.

[0034] The first servo motor rotates, driving the driving shaft to rotate through the belt. After the material belt on the material roll passes through the film taking station, it passes through the second feeding roller, the driving shaft, the first feeding roller in sequence and reaches the waste film collecting wheel. The material roll drives the rotation of the first feeding roller, the driving shaft, the second feeding roller and the waste film collecting wheel. When the waste film passes through the driving shaft, the film supply lifting cylinder drives the clamping wheel to rise and clamp the waste film to prevent the waste film from wrinkling and deformation, and avoid the problem of difficulty in discharging the material.

[0035] For further information, see Figure 6-7The film sticking mechanism 5 includes an X-axis linear module 50, an X-axis servo motor 51, a Y-axis linear module 52, a Y-axis servo motor 53 and a film taking assembly 54 for sucking the protective film on the film taking station.

[0036] Specifically, the film taking assembly 54 includes a film taking lifting cylinder 542 fixed on the Y-axis linear module through a mounting plate 541, a first slide cylinder 543 arranged below the film taking lifting cylinder, and a connecting plate 544 fixedly installed on the slide of the first slide cylinder. A film taking servo motor 545 is arranged on the connecting plate, and the output shaft of the film taking servo motor is connected to a hollow rotating platform 546. A film taking plate 547 is arranged below the hollow rotating platform. A plurality of vacuum holes are opened on the film taking plate, which are connected to a vacuum suction device for sucking products. An induction sheet 549 cooperating with a sensor 548 is arranged on the film taking plate.

A limit screw (not shown in the figure) is provided on the lower surface of the hollow rotating platform, which can cooperate with the induction sheet to limit the number of rotations of the film taking plate.

[0037] In a specific embodiment, the X-axis servo motor drives the X-axis linear module to move and then drives the Y-axis linear module and the film taking assembly to move in the X-axis direction. The Y-axis servo motor drives the Y-axis linear module to move and then drives the film taking assembly to move in the Y-axis direction. The film taking lifting cylinder presses the film suction plate down to the top of the product. The film taking lifting cylinder is floatingly connected to the connecting plate. When it descends, it directly pushes the connecting plate down to vacuum absorb the film. The film taking lifting cylinder rises, and the ion wind rod 11 on the lower frame performs dust removal on the film. When the film taking lifting cylinder rises, the film taking plate does not rise with the cylinder. After the film is taken, the lower CCD camera (not shown in the figure) takes a photo to detect the position of the protective film, and the upper CCD camera 12 detects the position of the product in the turntable fixture. The film taking servo motor drives the hollow rotating platform to rotate and adjusts the position of absorbing the protective film to ensure the accuracy of film sticking. Then the X and Y linear modules cooperate to move the film taking mechanism to the top of the turntable fixture, and the first slide cylinder descends to stick the protective film to the product.
