DETAILED DESCRIPTION

[0018] Example 1

[0019] like Figures 1 to 4As shown in the figure, the utility model discloses a screen printing film positioning and laminating device. The adopted technical solution is as follows: it includes a workbench 1. At the four corners of the bottom of the workbench 1, support legs 12 are respectively and fixedly installed. In the middle of the rear end of the upper surface of the workbench 1, a laminating unit is arranged. The laminating unit is composed of a slide bar 6, a lifting frame 7, a fixing plate 8, an electric telescopic rod 9 and a screen printing frame 10. There are two slide bars 6, and the slide bars 6 are symmetrically arranged on the left and right in the middle of the rear end of the upper surface of the workbench 1 respectively. At the top ends of the slide bars 6, fixing plates 8 are welded. In the middle of the fixing plate 8, an electric telescopic rod 9 is fixedly installed. The telescopic end of the electric telescopic rod 9 is fixedly connected with the lifting frame 7 slidably installed on the slide bar 6. At the front end of the lifting frame 7, a screen printing frame 10 is fixedly installed. Right below the screen printing frame 10, a base material frame 2 is arranged. The base material frame 2 is movably placed in the middle of the upper surface of the workbench 1. In the placement groove arranged at the top of the base material frame 2, a base material sheet 11 is movably placed. The screen printing frame 10 is of a square structure, and the shape of the screen printing frame 10 matches that of the base material frame 2 and the base material sheet 11. By running the electric telescopic rod 9, the telescopic end of the electric telescopic rod 9 pushes the lifting frame 7 to move downward along the slide bar 6, so that the pattern in the screen printing frame 10 is precisely laminated with the pre-printed area on the base material sheet 11. In the center of the bottom of the workbench 1, a rectangular groove 13 is arranged. Above the rectangular groove 13, a sliding groove 14 is arranged. There are four sliding grooves 14, and the sliding grooves 14 are respectively arranged in an equidistant circular array in the middle of the workbench 1. Inside the rectangular groove 13, a positioning unit 5 is arranged. The positioning unit 5 is composed of a motor 51, a connecting frame 52, a turntable 53, a guide groove 54 and a guide block 55. The connecting frame 52 is of a "U" shape structure. The connecting frame 52 is fixedly installed at the bottom of the workbench 1. At the center of the bottom of the connecting frame 52, a motor 51 is fixedly installed. The output shaft of the motor 51 passes through the through hole arranged at the center of the connecting frame 52 and is fixedly connected with the center of the bottom of the turntable 53 arranged inside the rectangular groove 13. On the turntable 53, four guide grooves 54 are arranged in an equidistant circular array. The guide grooves 54 are of an arc structure. Inside the guide grooves 54, guide blocks 55 are respectively slidably installed. The top parts of the guide blocks 55 are respectively fixedly connected with the clamping components 4 slidably installed in the sliding grooves 14. By running the motor 51, its output shaft drives the turntable 53 to rotate in the rectangular groove 13. Since the guide grooves 54 on the turntable 53 are of an arc structure, when the turntable 53 rotates, the guide grooves 54 drive the guide blocks 55 and the clamping components 4 fixed to their tops to slide along the sliding grooves 14. The clamping component 4 is composed of a moving block 41, a compression spring 42, a push plate 43, a pressure sensor 44 and a clamping plate 45. In the middle of the front and rear sides inside the sliding groove 14, slide rails 15 are respectively arranged, and the slide rails 15 are respectively slidably connected with the grooves arranged on the front and rear sides of the moving block 41, so that when the moving block 41 moves along the sliding groove 14, it can slide smoothly along the slide rails 15. The moving block 41 is of a "匚" shape structure. The moving blocks 41 are respectively fixedly installed at the tops of the guide blocks 55. Inside the cavities arranged at the tops of the moving blocks 41, push plates 43 are respectively slidably installed. On one side of the push plates 43, compression springs 42 are respectively fixedly installed.The other end of the compression spring 42 is fixedly connected to the inner wall of the top cavity of the moving block 41, and the other side of the push plate 43 is fixedly installed with a pressure sensor 44. The other end of the pressure sensor 44 passes through the through slot set at one end of the top cavity of the moving block 41 and is fixedly connected to the clamping plate 45. When one or two clamping plates 45 contact the outer side of the bottom material frame 2, the bottom material frame 2 is pushed to move toward the center of the workbench 1. At this time, the force exerted on the clamping plate 45 acts on the push plate 43 through the pressure sensor 44, so that the push plate 43 squeezes the compression spring 42, and the pressure sensor 44 monitors the pressure change of the clamping plate 45 in real time and transmits the signal to the controller 3. When the four pressure sensors 44 detect the preset pressure, the controller 3 controls the motor 51 to stop running, thereby realizing the precise positioning of the bottom material frame 2. The controller 3 is also included. The controller 3 is fixedly installed on the right front end of the upper surface of the workbench 1. The output end of the controller 3 is electrically connected to the input end of the motor 51 and the electric telescopic rod 9, and the input end of the controller 3 is electrically connected to the output end of the pressure sensor 44 and the external power supply.

[0020] The working principle of the utility model is as follows: first, the bottom material sheet 11 is placed in the bottom material frame 2, and the bottom material frame 2 is movably placed on the workbench 1, and then, the motor 51 is started through the controller 3. When the motor 51 is running, its output shaft drives the turntable 53 to rotate in the rectangular groove 13. Since the guide groove 54 on the turntable 53 is an arc-shaped structure, when the turntable 53 rotates, the guide groove 54 drives the guide block 55 and the moving block 41 fixed on its top to move in the slide groove 14, and the moving block 41 slides smoothly along the slide rail 15, and the moving block 41 gathers around the bottom material frame 2 at the same time, until one or two clamps 45 contact the outside of the bottom material frame 2, pushing the bottom material frame 2 to the center of the workbench 1 The force exerted on the clamping plate 45 at this time acts on the push plate 43 through the pressure sensor 44, so that the push plate 43 squeezes the compression spring 42, and the pressure sensor 44 monitors the pressure change of the clamping plate 45 in real time, and transmits the signal to the controller 3. When the four pressure sensors 44 all detect the preset pressure, the controller 3 controls the motor 51 to stop running, so as to realize the precise positioning of the base material frame 2, that is, the position of the base material frame 2 is located directly below the silk screen frame 10. Next, the electric telescopic rod 9 is controlled by the controller 3 to work, and the telescopic end of the electric telescopic rod 9 pushes the lifting frame 7 to move downward along the slide rod 6, so that the pattern in the silk screen frame 10 is precisely fitted with the pre-printed area on the base material sheet 11.
