Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Example 1

[0070] See Figures 1-6A car hinge protective film applicator includes: a frame 1; a base plate 2 mounted on the frame 1; a first positioning mechanism 4 mounted on the base plate 2, capable of positioning a first hinge; a second positioning mechanism 6 mounted on the base plate 2, capable of positioning a second hinge; a first film applicator 3 mounted on the base plate 2, capable of applicating film to the first hinge mounted on the first positioning mechanism 4; and a second film applicator 5 mounted on the base plate 2, capable of applicating film to the second hinge mounted on the second positioning mechanism 6. This machine can automatically complete the film applicator process for car hinges and can simultaneously applicate film to two types of hinges, exhibiting a high degree of automation and high work efficiency.

[0071] The first film-applying mechanism 3 includes: a winding mechanism 31, mounted on the frame 1, which conveys the film roll; a feeding and tensioning mechanism 32, which delivers the film to the pickup position; a heating mechanism 33, mounted on the frame 1, which heats the film; a detection mechanism 34, mounted on the frame 1, which detects whether film is present at the pickup position; and a gripping mechanism 35, mounted on the frame 1, which grips the film at the pickup position and applies it to the hinge. Through the actions of this series of mechanisms, the film is transferred from the raw material roll to the hinge, achieving the purpose of application.

[0072] The winding mechanism 31 includes: a raw material roll 311, rotatably mounted on the frame 1; a waste material roll 312, rotatably mounted on the frame 1; and guide wheels 313, a series of which are rotatably mounted on the frame 1. The raw material from the raw material roll 311 enters the feeding and tensioning mechanism 32 via the guide wheels 313, and the waste material roll is then wound onto the waste material roll 312 via the guide wheels 313. The raw material roll 311 rotates, and the guide wheels 313 and the conveyor belt pull the raw material roll 311 to rotate, thus conveying the conveyor belt. The conveyor belt has a film attached; after being gripped by the gripping mechanism 35, the waste material belt is then wound onto the waste material roll 312.

[0073] The feeding tensioning mechanism 32 includes: a tensioning cylinder 321, fixedly mounted on the frame 1; a tensioning slide, slidably mounted on the tensioning cylinder 321, with the piston rod of the tensioning cylinder 321 connected to the tensioning slide; and a support plate 322, fixedly mounted on the tensioning slide, which supports the material roll. The tensioning slide is slidably mounted on the tensioning cylinder 321, which provides a supporting force to the tensioning slide because a downward squeezing force is generated during the film adsorption process by the suction cup 354. The fixed tensioning cylinder 321 provides a supporting force to the support plate 322, making the support plate 322 more stable and reliable. The material roll is wound around the support plate 322 and supported by it.

[0074] The tensioning guide wheel 323 is rotatably mounted on the support plate 322, and the waste roll is wound around the tensioning guide wheel 323; after passing through the tensioning guide wheel 323, the waste roll is wound onto the waste material roll 312. The feeding and tensioning mechanism 32 has both feeding and tensioning functions. When tensioning is required, the support plate 322 and the tensioning guide wheel 323 can be moved by the tensioning cylinder 321 to tighten the material strip and achieve the tensioning effect.

[0075] The raw material in the material roll 311 enters the feeding and tensioning mechanism 32 after passing through the heating mechanism 33. The heating mechanism 33 has a heating seat 331, on which a heating cylinder 332 is mounted. A heating plate 333 is mounted on the piston rod of the heating cylinder 332. The heating plate 333 can heat the raw material on the material roll. The film on the material roll is adhered to the roll material. By heating, the adhesive can be loosened, making it easier for the subsequent picking mechanism to grasp.

[0076] The detection mechanism 34 includes a detection cylinder 341, and a detection camera 342 is mounted on the piston rod of the detection cylinder 341. The detection camera 342 can extend into the pickup position and detect whether there is a film applied at the pickup position. If there is a film applied at the pickup position, the subsequent gripping mechanism 35 moves to grip the film. If there is no film applied, the roll is conveyed forward to another station for another detection.

[0077] The gripping mechanism 35 has a gripping guide rail 351, which is fixedly mounted on the frame 1. A gripping slide 352 is slidably mounted on the gripping guide rail 351. A gripping cylinder 353 is mounted on the gripping slide 352. A suction cup 354 is mounted on the piston rod of the gripping cylinder 353. The suction cup 354 can adsorb the material on the material roll. The gripping slide 352 moves back and forth to grip the film and then transfers and pastes the film onto the hinge.

[0078] The bottom of the winding mechanism 31 is also provided with a straightening mechanism 36, which includes: a straightening linear module 361, fixedly mounted on the base plate 2; a straightening seat 362, mounted on the slider of the straightening linear module 361; a straightening pressure plate 363, fixedly mounted on the straightening seat 362; and a rubber block, mounted on the straightening pressure plate 363, with protrusions on the rubber block for squeezing the waste roll. The bottom of the winding mechanism 31 is also provided with a straightening mechanism 36. After the film is removed from the winding mechanism, the material roll needs to be wound onto the waste roll. During the winding process, the material roll is easily twisted due to the stress generated by the previous process, and warping is likely to occur when wound onto the waste roll. Therefore, the straightening mechanism 36 is provided. The straightening linear module 361 of the straightening mechanism 36 can push the straightening pressure plate 363 to move. The straightening pressure plate 363 is provided with a rubber block and protrusions, which can squeeze the waste roll and generate a pulling force to straighten the material roll, facilitating the winding of the waste roll.

[0079] The first film-applying mechanism 3 has two rows of film on its raw material roll; the gripping mechanism 35 of the first film-applying mechanism 3 has two sets of gripping cylinders 353 and suction cups 354; the two sets of gripping cylinders 353 and suction cups 354 can respectively adsorb the two rows of film; the detection mechanism 34 of the first film-applying mechanism 3 has two sets of detection cameras 342 on its detection cylinder 341; the two sets of detection cameras 342 can respectively detect the two rows of film; the first positioning mechanism 4 includes a first positioning seat 41, and the first positioning seat 41 is provided with a first positioning pin 42 for positioning the first hinge.

The raw material roll 311 rotates, and the guide wheels 313 and the conveyor belt pull the raw material roll 311 to rotate, thus conveying the conveyor belt. The conveyor belt has a film attached; after being gripped by the gripping mechanism 35, the waste material belt is then wound onto the waste material roll 312.
