[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5This utility model discloses a precision die-cutting device for polyimide film, comprising a table 1 and a die-cutting mounting plate 16 disposed above a die-cutting table 2. The die-cutting table 2 is slidably connected to the middle of the table 1. A vacuum adsorption table 3 is provided on the top side of the die-cutting table 2. A U-shaped mounting frame 4 is fixedly connected to the bottom of the table 1 and below the die-cutting table 2. A first electric push rod 5 is fixedly connected to the bottom of the mounting frame 4. The top end of the piston rod of the first electric push rod 5 is fixedly connected to the bottom of the die-cutting table 2. A blower unloading assembly is provided at the bottom of the table 1 and on one side of the die-cutting table 2. The blower unloading assembly includes a fan 6 fixedly connected to the bottom of the table 1 and a blower pipe 7 fixedly connected to the bottom of the table 1. The blower nozzle of the blower pipe 7 faces the die-cutting table 2. The blower pipe 7 is connected to the fan 6 through a pipe. A collection box 9 is provided at the bottom of the table 1 and on the side of the die-cutting table 2 away from the blower unloading assembly.

[0026] After the film is conveyed to the die-cutting table 2, the die-cutting blade is driven downwards to die-cut the film, separating the part to be die-cut from the film. The die-cut film is firmly adsorbed by the vacuum adsorption table 3 to ensure stability during movement. At this time, the first electric push rod 5 drives the die-cutting table 2 and the film on it to one side of the air blowing pipe 7, and the vacuum adsorption table 3 stops adsorption. The blower 6 starts, and the air blowing pipe 7 blows airflow onto the polyimide film on the die-cutting table 2 to achieve rapid film detachment and unloading. The collection box 9 facilitates the collection of the unloaded film. The die-cutting table 2 is reset upwards under the action of the first electric push rod 5, and subsequent die-cutting work can be carried out. By setting up the die-cutting table 2, the vacuum adsorption table 3 and the air blowing pipe 7, the automatic unloading of polyimide film after die-cutting is realized, which facilitates continuous die-cutting processing, thereby helping to improve die-cutting efficiency and has strong practicality.

[0027] The top of the table 1 is provided with a feeding assembly, which includes two second fixed plates 14 symmetrically fixedly connected to the top of the table 1, two guide rollers 17 installed on the top of the table 1 and located on both sides of the die-cutting table 2, two first fixed plates 12 fixedly connected to the top of the table 1 and located away from the second fixed plates 14, a take-up roller 13 rotatably connected between the first fixed plates 12 and a motor 15. The motor 15 is fixedly connected to one side of one of the first fixed plates 12, and one end of the take-up roller 13 is fixedly connected to the output shaft of the motor 15. The top side of each of the second fixed plates 14 is provided with a placement groove.

[0028] The polyimide film roll to be die-cut is inserted into the placement groove. The film passes through the bottom of the two guide rollers 17 in sequence. The die-cut film waste is wound onto the take-up roller 13. Driven by the motor 15, the take-up roller 13 is rotated, which can realize the feeding of film and the take-up of film waste, so as to better carry out continuous die-cutting work and improve production efficiency.

[0029] An L-shaped mounting bracket 10 is fixedly connected to the top of the table 1 and to one side of the die-cutting table 2. A second electric push rod 11 is fixedly connected to the top of the mounting bracket 10. A die-cutting mounting plate 16 is fixedly connected to the bottom end of the piston rod of the second electric push rod 11. After the die-cutting tool is installed on the die-cutting mounting plate 16, the second electric push rod 11 can drive the die-cutting tool to perform die-cutting operation.

[0030] Four casters are evenly installed on the bottom of the collection box 9, and a handle is fixedly connected to one side of the collection box 9 for easy movement and positioning. A notch is opened on the side of the collection box 9 near the die-cutting table 2, and the die-cutting table 2 is movably connected to the inside of the notch, so that when the die-cutting table 2 falls into the collection box 9, the film material on the die-cutting table 2 can be closer to the inside of the collection box 9, so that the film material falls into the collection box 9 better.

[0031] To ensure the stability of the collection box 9 when receiving film material, two L-shaped limiting plates 8 are fixedly connected to the bottom of the platform 1 and the side near the collection box 9. The collection box 9 is slidably connected between the limiting plates 8, which ensures the accuracy of the position of the collection box 9 when receiving film material.

[0032] Working principle:

[0033] The polyimide film roll to be die-cut is inserted into the placement groove. The film passes through the bottom of the two guide rollers 17 in sequence. The die-cut film waste is wound onto the take-up roller 13. Under the drive of the motor 15, the take-up roller 13 is rotated, which can realize the feeding of film and the take-up of film waste.

[0034] After the film is conveyed to the die-cutting table 2, the die-cutting blade is driven downwards to die-cut the film, separating the part to be die-cut from the film. The die-cut film is firmly adsorbed by the vacuum adsorption table 3 to ensure stability during movement. At this time, the first electric push rod 5 drives the die-cutting table 2 and the film on it to one side of the air blowing pipe 7, and the vacuum adsorption table 3 stops adsorption. The blower 6 starts, and the air blowing pipe 7 blows airflow onto the polyimide film on the die-cutting table 2 to achieve rapid film detachment and unloading. The collection box 9 facilitates the collection of the unloaded film. The die-cutting table 2 is reset upwards under the action of the first electric push rod 5, and subsequent die-cutting work can be carried out. By setting up the die-cutting table 2, the vacuum adsorption table 3 and the air blowing pipe 7, the automatic unloading of polyimide film after die-cutting is realized, which facilitates continuous die-cutting processing, thereby helping to improve die-cutting efficiency and has strong practicality.
