[0024] In order to solve the problems existing in the prior art, according to one aspect of the present application, a PI film roll shaping device is disclosed. Figures 1 to 5 As shown, the device includes a film roll shaping frame component 1, a feeding component 2, and a film roll shaping component 3.

The film roll shaping component 3 includes a plurality of film roll jigs and two shaping jigs arranged in sequence in the length direction of the support frame 11 away from the feeding component 2. A film roll groove is provided on the film roll jig. The circumference of the rear film roll groove of the PI film 7 on the rear film roll jig is achieved by superimposing the circumference of the front film roll groove on the front film roll jig of the PI film 7 on the target circumference. ; Among them, the rear film roll jig is the film roll jig adjacent to the rear side of the front film roll jig; the two shaping jigs include an initial shaping jig 34 and a target shaping jig 35, the initial shaping jig 34 is arranged between the target film roll jig 33 and the target shaping jig 35, and the target film roll jig 33 is the film roll jig farthest from the feeding component 2 among the multiple film roll jigs; the initial shaping jig 34 performs initial shaping on the target PI film roll obtained by rolling the target film roll jig 33 based on the initial shaping groove 341 to obtain an initial shape PI film roll, and the target shaping jig 35 performs target shaping on the initial shape PI film roll based on the target shaping groove 351 to obtain a target shape PI film roll.

[0025] Specifically, the number of film roll fixtures can be specifically set based on the requirements of the circumference of the film roll.

[0026] In some embodiments, the film roll shaping component 3 may include two film roll jigs, namely the initial film roll jig 31 and the target film roll jig 33 mentioned above, the initial film roll jig 31 is provided with an initial film roll groove 311, the initial film roll groove 311 is constructed as a semicircular structure with a target circumference, and the target film roll jig 33 is provided with a target film roll groove 331, the target film roll groove 331 is a spiral structure with a first target multiple target circumference. In this example, the first target multiple may refer to 4 times, that is, the circumference of the target film roll groove is 4 times the circumference of the initial film roll groove 311.

[0027] In some other embodiments, the film roll shaping component 3 may further include an intermediate film roll jig 32, which is arranged between the initial film roll jig 31 and the target film roll jig 33. An intermediate film roll groove is opened on the intermediate film roll jig 32, and the intermediate film roll groove is a spiral structure with a target circumference of a second target multiple, and the second target multiple is smaller than the first target multiple.

[0028] It is understandable that the number of the intermediate film rolling jigs 32 can be one or more, and the specific number can be set based on the actual film rolling requirements. In this example, there are four intermediate film rolling jigs 32. Specifically, Figure 1 As shown, the film roll shaping component 3 includes an initial film roll jig 31, four intermediate film roll jigs 32 and a target film roll jig 33, the four intermediate film roll jigs 32 are arranged between the initial film roll jig 31 and the target film roll jig 33, the four intermediate film roll jigs 32 include a first film roll jig 321, a second film roll jig 322, a third film roll jig 323 and a fourth film roll jig 324, the initial film roll groove 311 of the initial film roll jig 31 is the target circumference, the first film roll groove 3211 opened on the first film roll jig 321 is a spiral with a first circumference, and the length of the first circumference is twice the target circumference of the initial film roll groove 311 of the initial film roll jig 31 The second film rolling fixture 322 has a second film rolling groove 3221, which is a spiral with a second circumference, and the length of the second circumference is 2.5 times the target circumference of the initial film rolling groove 311. The third film rolling fixture 323 has a third film rolling groove 3231, which is a spiral with a third circumference, and the length of the third circumference is 3 times the target circumference of the initial film rolling groove 311. The fourth film rolling groove 3241 is a spiral with a fourth circumference, and the length of the fourth circumference is 3.5 times the target circumference of the initial film rolling groove 311. The target circumference of the target film rolling groove 331 is 4 times the target circumference.

[0029] It can be understood that in order to achieve better stacking between the PI film roll layers after film rolling, the circumference of the rear film rolling groove of the rear film rolling fixture can be enlarged by a multiple of the circumference of the front film rolling groove of the front film rolling fixture. The specific magnification factor can be set based on actual needs and is not specifically limited here.

[0030] It is understandable that the number of the intermediate film rolling fixtures 32 may be other numbers, which is not specifically limited here.

[0031] It can be understood that the technical solution realizes automatic film rolling and shaping of the PI film 7 by setting film rolling grooves and shaping jigs, which will not be affected by human subjectivity, thereby improving the film rolling efficiency and film rolling accuracy. Moreover, by setting multiple film rolling shaping jigs, the film rolling operation of the PI film 7 can be carried out in stages, which can be adjusted according to actual needs to adapt to PI films 7 of different specifications and thicknesses, thereby improving the flexibility of production, and the film rolling groove design opened on the film rolling jig allows the circumference of the film to be adjusted according to different needs, which helps to achieve diversified product specifications; further, by setting the initial shaping jig 34 and the target shaping jig 35, the PI film is shaped in stages, which reduces the stress concentration of the material, improves the uniformity of shaping, and improves the quality of the target shape PI film: further, the setting of the intermediate film rolling jig 32, combined with the spiral structure of the groove, can realize progressive film rolling, gradually adjust the shape and size of the film, reduce material stress, and improve the uniformity of film shaping.

[0032] In some embodiments, the feeding assembly 2 includes a feeding main roller 21, a main roller bracket 22, a first feeding auxiliary cylinder 23, a first auxiliary bracket 24, a second feeding auxiliary cylinder 25 and a second auxiliary bracket 26. The feeding main roller 21 is supported above the support frame 11 by the main roller bracket 22, the first feeding auxiliary cylinder 23 is supported below the support frame 11 by the first auxiliary bracket 24, and the second feeding auxiliary cylinder 25 is supported on the support frame 11 by the second auxiliary bracket 26. The first feeding auxiliary cylinder 23 can move up and down relative to the first auxiliary bracket 24. The PI film is drawn out from the feeding main roller 21, and then goes around the first feeding auxiliary cylinder 23 and the second feeding auxiliary cylinder 25 to the film roll shaping assembly 3. It can be understood that this solution can adjust the tension and feeding height of the PI film 7 by adjusting the height of the first feeding auxiliary cylinder 23, thereby improving the transportation stability of the PI film 7 raw material.

[0033] In some embodiments, the device also includes a shaping and cutting frame assembly and a shaping and cutting assembly 5. The shaping and cutting frame assembly is arranged on one side of the roll film shaping frame assembly 1, and the shaping and cutting assembly 5 is arranged above the shaping and cutting frame assembly. The shaping and cutting assembly 5 includes a docking block 51, a cutting scissors 52, and a square tube 53 clamp. The docking block 51 is installed close to the target shaping jig 35. A docking groove is provided on the docking block 51. The docking block 51 slides relative to the target shape PI roll film. After sliding, the docking block 51 docks with the square tube 53 clamped by the square tube 53 clamp to assist the target shape PI roll film to pass through the square tube 53. The cutting scissors 52 are arranged between the docking block 51 and the square tube 53 to cut the target shape PI roll film. It can be understood that the sliding design between the docking block 51 and the target shape PI roll film ensures that the film material can be accurately docked to the square tube 53 clamp, reduces the error in the docking process, and improves the accuracy of the operation.

[0034] In some embodiments, the device also includes a conveying component 6, which includes a support column and a conveying auxiliary plate 61. One end of the support column is installed on the shaping and cutting frame assembly, and the other end of the support column is supported under the conveying auxiliary plate 61. A conveying groove 62 is opened on the conveying auxiliary plate 61, and the target shape PI roll film is conveyed along the conveying groove 62 to the shaping and cutting component 5.

[0035] It can be understood that by conveying the target shape PI roll film along the conveying groove 62, the groove structure of the conveying groove 62 provides a relatively stable conveying path for the target shape PI roll film, reducing the displacement or damage of the target shape PI roll film during the conveying process, thereby improving the safety of transportation, and the design of the conveying groove 62 allows the PI film to move smoothly along the set trajectory, reducing friction and resistance, and improving the conveying efficiency.

[0036] In some embodiments, the conveying assembly 6 further includes a pressing plate 63 , which is mounted on the conveying auxiliary plate 61 , and the pressing plate 63 spans across both sides of the conveying trough 62 .

[0037] It can be understood that, by the pressure plate 63 acting on the conveying auxiliary plate 61, the target-shaped PI roll film can be confined in the conveying groove 62, thereby reducing the accidental falling off of the film material during the conveying process and improving the safety of the operation.

[0038] In some embodiments, the conveying component 6 also includes a front clamping component 64 and a rear clamping component 65, and the front clamping component 64 and the rear clamping component 65 are respectively located at both ends of the conveying auxiliary plate 61, and the target shape PI roll film passes through the front clamping component 64, the conveying trough 62 and the rear clamping component 65 in sequence, and the front clamping component 64 and the rear clamping component 65 have an asynchronous clamping action on the target shape PI roll film.

[0039] In some embodiments, the front clamping assembly 64 includes a front upper clamping plate 641 and a front lower clamping plate 642, and the front upper clamping plate 641 and the front lower clamping plate 642 are moved closer to or farther away from each other to achieve the clamping or loosening of the target shape PI roll film. The rear clamping assembly 65 includes a rear upper clamping plate 651 and a rear lower clamping plate 652, and the rear upper clamping plate 651 and the rear lower clamping plate 652 are moved closer to or farther away from each other to achieve the clamping or loosening of the target shape PI roll film. When the target shape PI roll film is clamped by the front clamp, the target shape PI roll film is loosened by the rear clamp. When the target shape PI roll film is loosened by the front clamp, the target shape PI roll film is clamped by the rear clamp. Specifically, in this example, the rear upper clamp 651 and the rear lower clamp 652 move closer to each other to clamp the target shape PI roll film. At this time, the front upper clamp 641 and the front lower clamp 642 move away from each other, and the front clamping component 64 has no effect on the target shape PI roll film, so that the target shape PI roll film is clamped by the rear clamping component 65 and moved toward the direction close to the square tube. After moving into place, the rear upper clamp 651 and the rear lower clamp 652 move away from each other, and the rear clamping component 65 releases the target shape PI roll film. At this time, the front upper clamp 641 and the front lower clamp 642 are controlled to move closer to each other to clamp the target shape PI roll film. When the target shape PI roll film is clamped, the cutting scissors 52 are controlled to cut the target shape PI roll film, and further enter the next square tube for PI film filling.

[0040] It can be understood that the asynchronous clamping design of the front clamping component 64 and the rear clamping component 65 can realize flexible control of the target shape PI film roll, avoid material displacement during clamping and loosening, and improve cutting accuracy; and this solution simplifies the operation process by integrating film rolling, shaping, conveying, clamping and cutting functions, reduces the need for manual intervention, and improves the automation level of film roll shaping.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
