All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0021] Embodiment 1:
[0022] As Figures 1 - 8 shown, a film cutting die provided by the present utility model includes a substrate 1, on which an assembly 2 is fixedly installed. On both sides of the bottom of the substrate 1, slide rails 3 are symmetrically and fixedly installed. A longitudinal tool holder 4 and a transverse tool holder 5 are slidably connected to the slide rails 3. The longitudinal tool holder 4 is fixedly connected to the transverse tool holder 5 through a connecting member 6. The longitudinal tool holder 4 is provided with a longitudinal tool rail 7, and the transverse tool holder 5 is provided with a transverse tool rail 8. Tools 10 are fixedly installed on both the longitudinal tool rail 7 and the transverse tool rail 8 through fixing bolts 9. A switching device 11 is fixedly installed on the top of the substrate 1. The switching device 11 includes a fixing frame 12, a driving motor 13, and a lead screw 14. The fixing frame 12 fixedly installs the driving motor 13, and the driving motor 13 is drivingly connected to the lead screw 14. The lead screw 14 is connected to the connecting member 6 through a connecting arm 15. The tool 10 includes an assembly plate 16 and a blade 17, and the blade 17 is fixedly installed on the assembly plate 16. The fixing bolt 9 includes a guiding block 18, a crown block 19, and a fixing block 20. The guiding block 18 is provided with a screw hole 21, and a bolt 22 is fixedly installed in the screw hole 21. A photoelectric sensor 23 is fixedly installed on the fixing frame 12. The connecting arm 15 is movably connected to the lead screw 14 through a lead screw nut.
[0023] Through the above technical solution, the substrate 1 of the present utility model is movably installed with a longitudinal tool holder 4 and a transverse tool holder 5 through the slide rails 3. The longitudinal tool holder 4 and the transverse tool holder 5 are fixedly connected through a connecting member 6. The connecting member 6 is fixedly installed with a connecting arm 15. The driving motor 13 drives the connecting arm 15 through the lead screw 14 to switch the longitudinal tool holder 4 and the transverse tool holder 5. Both the longitudinal tool holder 4 and the transverse tool holder 5 are installed with tools 10 through tool rails. During use, the present utility model is installed on the pressing device of the film cutting equipment, and the present utility model is pressed down through the pressing device to complete the rapid cutting of the film. When the present utility model is working, the switching device 11 drives the longitudinal tool holder 4 and the transverse tool holder 5 to make the longitudinal tool holder 4 located directly above the film. Then, the present utility model is pressed down through the pressing device, so that the tool 10 on the longitudinal tool holder 4 cuts the film, and the film is cut into strips. The pressing device rises, and the switching device 11 drives the longitudinal tool holder 4 and the transverse tool holder 5 again to make the transverse tool holder 5 located directly above the film. Then, the present utility model is pressed down through the pressing device, so that the tool 10 on the longitudinal and transverse tool holders cuts the film, and the film is cut into blocks, quickly completing the film cutting process.
[0024] Embodiment 2:
[0025] As shown Figures 1 - 8 in the figure, the substrate 1 is the main support structure of the present utility model. The substrate 1 is fixedly installed with a fitting 2, which is used for installation on a machine, facilitating the installation of the present utility model on a film cutting device. A pressing device on the film cutting device is installed, and the cutting die is driven to press down through the pressing device to complete the rapid cutting of the film. The substrate 1 is symmetrically installed with slide rails 3 on both sides of the bottom. The function of the slide rails 3 is to provide a sliding connection for the longitudinal tool holder 4 and the transverse tool holder 5, enabling these two tool holders (longitudinal tool holder 4 and transverse tool holder 5) to move on the substrate 1. On the top of the substrate 1, a switching device 11 is fixedly installed. This switching device 11 includes a fixed frame 12, a driving motor 13, and a lead screw 14. The driving motor 13 is connected to the connecting arm 15 through the lead screw 14. The cooperation of these components enables the switching device 11 to accurately drive the position adjustment of the longitudinal tool holder 4 and the transverse tool holder 5.
[0026] The longitudinal tool holder 4 and the transverse tool holder 5 are fixedly connected through a connecting member 6. The longitudinal tool holder 4 is provided with a longitudinal tool rail 7, and the transverse tool holder 5 is provided with a transverse tool rail 8. The tool 10 is installed on these tool rails through a fixing bolt 9, enabling the tool 10 to move on the longitudinal and transverse tracks. When adjusting the position of the tool 10, film products of different sizes can be cut.
[0027] During the working process, first, the position of the longitudinal tool holder 4 is adjusted through the switching device 11 so that it is directly above the film. At this time, the pressing device is driven to apply pressure downward, and the tool 10 on the longitudinal tool holder 4 cuts the film, cutting the film into strips. After the longitudinal cutting is completed, the pressing device rises, and then the switching device 11 is driven again to adjust the transverse tool holder 5 to be directly above the film. The pressing device is driven to press down again, and at this time, the tool 10 on the transverse tool holder 5 cuts the film, further cutting the film into blocks.
[0028] The precise control during the cutting process depends on the adjustment of the spacing of the tool 10. By adjusting the spacing of the tool 10 on the longitudinal tool rail 7 or the transverse tool rail 8, the film of the required size can be flexibly cut to meet different processing requirements. Such a method not only improves the cutting speed but also ensures the cutting quality of the film and reduces the generation of waste.
[0029] The connection method between the support structure and the fittings is precisely designed to ensure that the equipment has sufficient stability and durability during operation. The sliding fit between the slide rails 3 and the tool holders ensures the accuracy of the tool 10 during cutting and reduces the cutting error caused by equipment loosening or displacement.
[0030] Overall, the film cutting die device of the present utility model not only improves the cutting efficiency but also enhances the cutting accuracy, making the processing of the film more in line with the production requirements of modern electronic products. By optimizing the structure and working principle of the cutting die, the present utility model can meet the high standards for film cutting in electronic products such as flexible AMOLED displays.
[0031] The cutting tool 10 of the present utility model includes an assembly plate 16 and a blade 17. The assembly plate 16, as the basic component of the cutting tool 10, is responsible for fixing the position of the blade 17. The blade 17 is the key element for actually cutting the film. With this design, the blade 17 can be stably installed on the assembly plate 16, thus ensuring the accuracy and efficiency during the cutting process. The main function of the assembly plate 16 is to provide a stable installation platform for the blade 17. The connection method between the assembly plate 16 and the blade 17 ensures that the blade 17 will not loosen or shift during the cutting process, which is crucial for maintaining the cutting accuracy. In actual operation, if the blade 17 is worn or damaged, it is only necessary to remove the blade 17 from the assembly plate 16 and replace it with a new blade 17, rather than replacing the entire cutting tool 10. This structural design greatly simplifies the maintenance and replacement process, significantly reducing the maintenance cost of the cutting tool 10. The process of replacing the blade 17 is relatively simple. First, the operator needs to disassemble the existing blade 17 from the assembly plate 16, which is achieved through the fixing bolt 9 or other connection methods. Then, the new blade 17 can be directly installed on the assembly plate 16. The connection method between the assembly plate 16 and the blade 17 ensures that the new blade 17 can be firmly fixed in the original position, avoiding instability problems during the cutting process. After completing the replacement of the blade 17, the cutting tool 10 can be put back into use without complex disassembly or recalibration of the entire cutting tool 10, which has a positive effect on improving production efficiency.
[0032] The components of the fixing bolt 9 of the utility model include a guide block 18, a crown block 19 and a fixing block 20. The guide block 18 is a key part of the fixing bolt 9, and it is provided with a screw hole 21, and the screw hole 21 is used to install a bolt 22. The design of the guide block 18 allows it to slide with the longitudinal knife track 7 or the transverse knife track 8, so that the fixing bolt 9 can slide linearly on these knife tracks. This sliding fit ensures the precise positioning of the tool 10 in the longitudinal and transverse directions, so that the film cutting process can be carried out according to the set size. The bolt 22 is installed in the screw hole 21 of the guide block 18, and the function of the bolt 22 is to fix the guide block 18 on the knife track to ensure the stability of the guide block 18. During operation, the fixing of the bolt 22 can prevent the guide block 18 from being displaced during the sliding process, thereby maintaining the accurate position of the tool 10. The guide block 18 can slide on the longitudinal knife track 7 or the transverse knife track 8 through sliding fit, so as to complete the cutting tasks in different directions. The fixing block 20 is used to install the tool 10. The cutter 10 is firmly mounted on the fixing bolt 9 by the fixing block 20, thereby ensuring that the cutter 10 remains stable during the cutting process. The design of the fixing block 20 enables the cutter 10 to be accurately aligned to the cutter track, which is essential for maintaining cutting accuracy. The process of installing the cutter 10 on the fixing block 20 is simple and reliable, and the cutter 10 can be quickly fixed in the correct position. The function of the crown block 19 is to mount the fixing bolt 9 on the longitudinal cutter track 7 or the transverse cutter track 8. The design of the crown block 19 ensures that the fixing bolt 9 can remain stable on the cutter track while allowing the fixing bolt 9 to slide on the cutter track. In this way, the cutter 10 can flexibly adjust its position during the cutting process to adapt to different cutting requirements. The presence of the crown block 19 not only provides additional stability, but also ensures that the fixing bolt 9 will not produce unnecessary swinging or shaking when sliding, thereby improving the accuracy and stability of the cutting.
[0033] The fixed frame 12 of the utility model is equipped with a photoelectric sensor 23, which detects the position change of the tool holder by emitting and receiving light. The sensor identifies the specific position of the tool holder by the discontinuity or reflection of the light beam. This method can accurately measure the movement of the tool holder in the working area. The photoelectric sensor 23 is installed on the fixed frame 12. This design ensures that the sensor can stably monitor the position of the tool holder without being interfered by other mechanical components. The light emitted by the sensor will be blocked by the reflective surface or object on the tool holder, thereby generating signal changes, which are received by the sensor and transmitted to the control system. The control system adjusts the position of the tool holder in real time according to the data fed back by the sensor to ensure the accuracy of the cutting operation.
[0034] The connecting arm 15 of the present utility model is movably connected to the lead screw 14 through a lead screw nut. As a key component connecting the longitudinal tool path 7 and the transverse tool path 8, the connecting arm 15 fixedly connects these two tool paths together through the connecting member 6. Driven by the driving motor 13, the lead screw 14 drives the movement of the lead screw nut through rotation, thereby driving the movement of the connecting arm 15. This structure enables the longitudinal tool path 7 and the transverse tool path 8 to move synchronously to achieve precise cutting adjustment. The cooperation between the lead screw nut and the lead screw 14 is the core of the movement of the connecting arm 15. The lead screw nut matches its internal thread with the external thread of the lead screw 14, enabling the rotation of the lead screw 14 to be effectively converted into the linear movement of the nut. When the lead screw 14 rotates driven by the motor, the lead screw nut moves along the lead screw 14, thereby driving the movement of the connecting arm 15. Through this precise thread fit, precise control of the positions of the longitudinal tool path 7 and the transverse tool path 8 can be achieved.
