Description

Technical Field

[0001] The invention relates to the technical field of polyimide film preparation, in particular to a bonding and compounding device for single-drawn polyimide films. Background Art

[0002] Polyimide films include two types: homophenyl polyimide films and biphenyl polyimide films. They have excellent thermal stability, chemical corrosion resistance and mechanical properties. At the same time, their chemical properties are very stable and can prevent combustion without the addition of flame retardants. Therefore, they are used for motor slot insulation and cable wrapping materials. Transparent polyimide films can be used as soft solar cell base plates.

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field of the present invention. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0035] In view of the problems existing in the prior art, an embodiment of the present invention provides a bonding and laminating device for a single-pulled polyimide film, which is intended to adjust the first base film and the second base film between the bonding and laminating roller shaft 1 to ensure that the first base film and the second base film remain flush when they reach the bonding and laminating roller shaft 1, such as Figure 1 As shown, the bonding and compounding equipment for single-pulled polyimide film includes a supporting frame 6, a bonding and compounding roller 1 arranged on the supporting frame 6, a first base film roller 2, a second base film roller 3 and a finished product roller 5, and an alignment adjustment mechanism 4 arranged on the side wall of the bonding and compounding roller 1. When working, the first base film wound on the first base film roller 2 and the second base film wound on the second base film roller 3 are aligned by the alignment adjustment mechanism 4, bonded and compounded by the bonding and compounding roller 1, and then wound on the finished product roller 5.

[0036] The first base film and the second base film shown in this embodiment may be the same or different. For example, both the first base film and the second base film may be polyimide films, or one of them may be a polyimide film, or neither of them may be a polyimide film.

[0037] In one embodiment, Figure 2 and Figure 4 As shown, the alignment adjustment mechanism 4 includes a U-shaped groove 41 fixedly arranged on the side wall of the bonding composite roller shaft 1, and a first alignment component 42 and a second alignment component 43 movably arranged in the U-shaped groove 41, and the first alignment component 42 and the second alignment component 43 move toward each other to adjust the alignment of the first base film and the second base film. The upper ends of the first alignment component 42 and the second alignment component 43 are fixedly connected with a supporting slider 45, and the supporting slider 45 is movably arranged in a supporting through hole 46, and the supporting through hole 46 is opened on the U-shaped groove 41.

[0038] In this embodiment, the first alignment component 42 and the second alignment component 43 move toward each other, so as to adjust the first base film and the second base film to be flush.

[0039] It should be noted that the structures of the first alignment component 42 and the second alignment component 43 are consistent, and the first alignment component 42 is described in this embodiment and the following for demonstration.

[0040] In one embodiment, Figure 3 As shown, the alignment adjustment mechanism 4 also includes a second guide support assembly 44, which is used to connect the first alignment assembly 42 with the inner wall of the U-shaped groove 41, and the second guide support assembly 44 is used to connect the second alignment assembly 43 with the inner wall of the U-shaped groove 41. The second guide support assembly 44 includes a second guide support rod 441, a second guide support cylinder 442 and a second guide support spring 443. The second guide support rod 441 is movably inserted in the second guide support cylinder 442, and the second guide support spring 443 is wound around the outside of the second guide support rod 441, and the two ends of the second guide support spring 443 are respectively fixedly connected to the side wall of the second guide support rod 441 and the outer wall of the second guide support cylinder 442.

[0041] The arrangement of the second guide support assembly 44 in this embodiment can not only play a guiding and supporting role for the movement of the first alignment assembly 42 and the second alignment assembly 43, but also provide a resetting force for the resetting movement of the first alignment assembly 42 and the second alignment assembly 43; and, the number of the second guide support assemblies 44 is set to be several, and the several second guide support assemblies 44 are divided into two groups, and the two groups of second guide support assemblies 44 are respectively used for connecting the first alignment assembly 42 and the U-shaped groove 41, and connecting the second alignment assembly 43 and the U-shaped groove 41.

[0042] In order to drive the first alignment component 42 and the second alignment component 43 to move toward each other or move away from each other, in one embodiment, Figure 4 As shown, the bonding and compounding equipment for single-pull polyimide film also includes two first driving mechanisms 7, and the two first driving mechanisms 7 are respectively connected to the first alignment component 42 and the second alignment component 43 to drive the first alignment component 42 and the second alignment component 43 to move closer to or away from each other, wherein the first driving mechanism 7 includes a driving cylinder 71 fixedly set on the top plate of the U-shaped groove 41, and a cylinder arm 72 connected to the driving end of the driving cylinder 71, and the free end of the cylinder arm 72 is fixedly connected to the side wall of the supporting slider 45.

[0043] The two first drive mechanisms 7 in this embodiment can synchronously drive the first alignment component 42 and the second alignment component 43 to achieve the first alignment component 42 and the second alignment component 43 to move closer to each other or move away from each other. In addition, the two first drive mechanisms 7 are of the same model and both provide driving force in a cyclic manner, so that the first alignment component 42 and the second alignment component 43 can move closer to each other or move away from each other in a cyclic manner, so that there is no need to stop the machine during the flush adjustment process, thereby improving production efficiency.

[0044] In the above embodiment, two first drive mechanisms 7 are provided, each equipped with two drive systems. Thus, when a power failure occurs in one of the drive systems, flush adjustment cannot be performed. Furthermore, providing two first drive mechanisms 7 and two drive systems will greatly increase production costs.

[0045] In order to solve the above problems, in one implementation, Fig.10As shown, the bonding and compounding equipment for single-pull polyimide film also includes a second driving mechanism 9, which includes a driving motor 91 fixed on a fixed seat 92, and the fixed seat 92 is fixed on the U-shaped groove 41. The driving end of the driving motor 91 is fixedly connected to a rotating disk 93, and the edge of the rotating disk 93 is hinged with a first push-pull rod 94, and the free end of the first push-pull rod 94 is hinged on the upper end surface of a moving column 95, and the moving column 95 is movably inserted in a fixed tube 96, and the fixed tube 96 is fixedly set on the U-shaped groove 41. Two movable through holes 97 are provided on the fixed tube 96, and second push-pull rods 98 are movably set in the two movable through holes 97, and one end of the two second push-pull rods 98 are hinged on the moving column 95, and the other end of the two second push-pull rods 98 are hinged on two supporting sliders 45.

[0046] The second drive mechanism 9 in this embodiment only provides a single power source to synchronously control the first alignment component 42 and the second alignment component 43, which can reduce production costs and equipment failure rates, and ensure that the flush adjustment process is carried out smoothly and efficiently. When working, the drive motor 91 is started, and the drive motor 91 will rotate the rotating disk 93. During the rotation of the rotating disk 93, the first push-pull rod 94 will pull the moving column 95 to make an up and down circular motion. The up and down circular motion of the moving column 95 will pull or push the first alignment component 42 and the second alignment component 43 to move closer to or away from each other through the second push-pull rod 98 and the support slider 45. Specifically, when the moving column 95 moves downward, the two second push-pull rods 98 will synchronously push the first alignment component 42 and the second alignment component 43 to move away from each other, and the movement distances of the first alignment component 42 and the second alignment component 43 are consistent.

[0047] During operation, when the first alignment component 42 or the second alignment component 43 contacts the first base film or the second base film, an impact may occur. The impact may cause damage to the first base film or the second base film. In order to prevent the impact force from causing damage to the first base film or the second base film, in one embodiment, Figure 5As shown, the first alignment component 42 includes a first alignment plate 421 and a second alignment plate 422, and a first guide support component 423 arranged between the first alignment plate 421 and the second alignment plate 422 and used to connect the first alignment plate 421 and the second alignment plate 422, the first guide support component 423 includes a first guide support rod 4231, a first guide support cylinder 4232 and a first guide support spring 4233, the first guide support rod 4231 is movably inserted in the first guide support cylinder 4232, the first guide support spring 4233 is wound around the outside of the first guide support rod 4231, and the two ends of the first guide support spring 4233 are respectively fixedly connected to the side wall of the first guide support rod 4231 and the outer side wall of the first guide support cylinder 4232.

[0048] In this embodiment, a first guide support assembly 423 is arranged between the first alignment plate 421 and the second alignment plate 422. The arrangement of the first guide support assembly 423 enables the first alignment plate 421 and the second alignment plate 422 to move toward or away from each other, so that when the second alignment plate 422 collides with the first base film and / or the second base film, the second alignment plate 422 will move toward the first alignment plate 421, and the first guide support assembly 423 will buffer the impact force, thereby protecting the first base film and / or the second base film; at the same time, the arrangement of the combined structure of the first alignment plate 421, the second alignment plate 422 and the first guide support assembly 423 enables the device to be applicable to first base films and second base films of different widths. It should be noted that the second alignment assembly 43 has the same structure as the first alignment assembly 42, which will not be described here; during the bonding and composite processing, the widths of the first base film and the second base film remain consistent.

[0049] In the actual leveling adjustment process, since the first alignment component 42 and the second alignment component 43 exert opposing forces on the first base film and the second base film, the middle parts of the first base film and the second base film may bulge and no longer maintain levelness, or the first base film and the second base film may be separated and no longer fit together. Both of these situations are not conducive to the subsequent bonding and laminating process. In order to solve the above problems, in one embodiment, as Figure 6 As shown, the bonding and composite equipment for single-pull polyimide film also includes a flattening mechanism 8, which includes a flattening plate assembly 81 arranged between the first alignment assembly 42 and the second alignment assembly 43, and a pressing groove 82 arranged below the flattening plate assembly 81, and a driving assembly 83 connected to the flattening plate assembly 81 and used to drive the flattening plate assembly 81 to move upward or downward.

[0050] The arrangement of the flattening mechanism 8 in this embodiment can flatten the first base film and the second base film from top to bottom during the process of the first alignment component 42 and the second alignment component 43 adjusting the first base film and the second base film to be flush, so that the first base film and the second base film can be ensured to enter the bonding composite roller 1 in a horizontal posture, and can also be ensured to enter the bonding composite roller 1 in a tightly fitting posture, thereby ensuring the preparation of high-quality finished composite films.

[0051] In order to ensure that the flushing process and the flattening process do not affect each other, in one embodiment, Figure 7 As shown, the driving assembly 83 includes a vertical rod 831 fixed on the upper end surface of the pressure plate assembly 81, and the upper end of the vertical rod 831 is fixedly connected with a fixed block 832, and the fixed block 832 is fixedly set on the first resistance block 833, and the first resistance block 833 is movably set in a movable groove 834, and the movable groove 834 is opened on the second alignment plate 422, and the first resistance block 833 is provided with a first anti-stuck groove 835, and the driving assembly 83 also includes a second resistance block 836 fixedly set on the side wall of the first alignment plate 421, and a second anti-stuck groove 837 opened on the second resistance block 836.

[0052] The drive assembly 83 in this embodiment is set up so that the flattening plate assembly 81 can be driven to move downward to complete the flattening process only after the flushing adjustment is completed. Specifically, when the second alignment plate 422 and the first base film and the second base film are in conflict with each other, the first alignment plate 421 will move toward the second alignment plate 422 as the pulling process progresses, and the second conflicting block 836 will conflict with the first conflicting block 833 as the movement proceeds, and the first conflicting block 833 will move downward, and the downward movement of the first conflicting block 833 will move the flattening plate assembly 81 downward through the vertical rod 831 and the fixed block 832 to complete the flattening process.

[0053] In one embodiment, Figure 7 As shown, the driving assembly 83 also includes a fourth guide support assembly 838, one end of which is fixed on the lower end surface of the first resistance block 833 and the other end is fixedly connected to the bottom wall of the movable groove 834. The fourth guide support assembly 838 includes a fourth guide support rod 8381, a fourth guide support cylinder 8382 and a fourth guide support spring 8383. The fourth guide support rod 8381 is movably inserted in the fourth guide support cylinder 8382, and the fourth guide support spring 8383 is wound around the outside of the fourth guide support rod 8381, and the two ends of the fourth guide support spring 8383 are respectively fixedly connected to the side wall of the fourth guide support rod 8381 and the outer side wall of the fourth guide support cylinder 8382.

[0054] The arrangement of the driving assembly 83 in this embodiment can not only play a guiding and supporting role for the movement of the first abutment block 833 , but also provide a restoring force for the restoring movement of the first abutment block 833 .

[0055] In order to avoid the influence of the pressing plate assembly 81 on the first alignment assembly 42 and the second alignment assembly 43 when they move toward or away from each other, in one embodiment, as shown in FIG. Figure 8 and Fig. 9 As shown, the pressure plate assembly 81 includes a first pressure plate 811 and a second pressure plate 812, and a connecting plate 813 arranged between the first pressure plate 811 and the second pressure plate 812, the bottom of the connecting plate 813 is respectively connected to the first pressure plate 811 and the second pressure plate 812 through an elastic plate 814, and the top of the connecting plate 813 is respectively connected to the first pressure plate 811 and the second pressure plate 812 through a third guide support assembly 815, the third guide support assembly 815 includes a third guide support rod 8151, a third guide support cylinder 8152 and a third guide support spring 8153, the third guide support rod 8151 is movably inserted in the third guide support cylinder 8152, the third guide support spring 8153 is wound around the outside of the third guide support rod 8151, and the two ends of the third guide support spring 8153 are respectively fixedly connected to the side wall of the third guide support rod 8151 and the outer side wall of the third guide support cylinder 8152.

[0056] In this embodiment, the length of the flat plate assembly 81 can adjust itself as the first alignment assembly 42 and the second alignment assembly 43 move toward or away from each other. This can not only achieve the flattening process through the flat plate assembly 81, but also prevent the flat plate assembly 81 from affecting the first alignment assembly 42 and the second alignment assembly 43 when they move toward or away from each other.

[0057] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
