Technical Field

[0001] This utility model belongs to the field of adhesive film technology, specifically an automatic device for softening adhesive films. Background Technology

[0002] Early adhesive films were mostly made from natural rubber or simple polymers, resulting in relatively limited performance. With the development of materials science, new polymer materials are constantly emerging. For example, in the photovoltaic industry, ethylene-vinyl acetate copolymer (EVA) films have become mainstream. Researchers have optimized the optical properties, thermal stability, and adhesion of EVA by adjusting the vinyl acetate (VA) content. Higher VA content results in films with better flexibility and stronger adhesion, allowing for tight bonding between solar cells and materials such as glass and backsheets. Specially modified EVA films also possess better resistance to UV aging, extending the lifespan of photovoltaic modules. In the field of electronic packaging, polyimide (PI) films stand out due to their excellent high-temperature resistance, insulation, and mechanical properties. Researchers have designed and controlled the molecular structure of PI to improve its adaptability in microelectronics manufacturing, meeting the high precision and high reliability requirements of chip packaging.

[0003] In many industrial production processes, such as photovoltaic module manufacturing and electronic device packaging, encapsulants are widely used. Before processing encapsulants, they often need to be softened to meet specific process requirements.

[0004] Traditional film softening requires manual winding of the film, which is inefficient and makes it difficult to ensure uniform heating of the film during the winding process, thus affecting product quality. Furthermore, when dust and impurities adhere to the film surface, the softening effect can be compromised.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides an automatic film softening device, including a processing table 1, on the surface of the processing table 1, a softening and cleaning component 2 is installed;

[0026] The softening and cleaning assembly 2 includes an unwinding roller 21, which is rotatably connected to the surface of the processing table 1, and a take-up roller 22 is rotatably connected to the other side of the processing table 1. Both the unwinding roller 21 and the take-up roller 22 are driven by a motor. A hydraulic rod 23 is installed on the surface of the processing table 1. The telescopic end of the hydraulic rod 23 is connected to the softening mechanism 24 set on the surface of the processing table 1, thereby realizing automated conveying and heating of the adhesive film, avoiding manual conveying, ensuring uniform heating of the adhesive film, and further improving the quality of the product.

[0027] A movable rod 26 is rotatably connected to the surface of the processing table 1. One end of the movable rod 26 passes through the processing table 1 and is connected to a support plate 27 located outside the processing table 1. A cleaning wheel 28 is provided on the bottom surface of the support plate 27. A cleaning cloth is covered on the surface of the cleaning wheel 28. A disassembly and replacement component 3 is installed on the surface of the cleaning wheel 28. The cleaning cloth cleans the impurities and adhesive residues adhering to the surface of the adhesive film, thereby enabling the adhesive film to be cleaned before heating and softening, and preventing impurities and adhesive residues adhering to the surface of the adhesive film from affecting the heating and softening effect.

[0028] Specifically, a torsion spring 29 is sleeved on the surface of the movable rod 26. One end of the torsion spring 29 is connected to the movable rod 26, and the other end of the torsion spring 29 is connected to the processing table 1. The torsion spring 29 can drive the movable rod 26 to reset, thus facilitating operation by the user.

[0029] like Figures 1 to 4 As shown, a positioning pin 210 is slidably connected in the through hole opened on the surface of the support plate 27. One end of the positioning pin 210 passes through the support plate 27 and is inserted into the insertion hole opened on the surface of the processing table 1. The surface of the processing table 1 has two insertion holes, which are used to position the support plate 27 in the vertical and horizontal positions respectively, so as to fix the position of the support plate 27.

[0030] Furthermore, a return spring 211 is fitted on the surface of the positioning pin 210. One end of the return spring 211 is connected to the positioning pin 210, and the other end of the return spring 211 is connected to the support plate 27. The return spring 211 can reset the position of the positioning pin 210.

[0031] It is worth noting that pressure rollers 25 are symmetrically installed on the surface of the processing table 1. The pressure rollers 25 can fix and guide the position of the adhesive film.

[0032] like Figures 1 to 4 As shown, the disassembly and replacement component 3 includes a disassembly strip 31. The surface of the cleaning wheel 28 is equipped with the disassembly strip 31, and the surface of the support plate 27 is equipped with a connecting strip 32. The disassembly strip 31 is snapped into the slot opened on the surface of the connecting strip 32, thereby realizing the replacement of the cleaning wheel 28 and avoiding the impact on the cleaning effect of the adhesive film when a large amount of dust and impurities are stuck on the cleaning cloth.

[0033] It is worth emphasizing that a bolt 33 is threaded into the threaded hole on the surface of the connecting strip 32. One end of the bolt 33 passes through the connecting strip 32 and is threaded into the threaded hole on the surface of the disassembly strip 31, which can stabilize the position of the disassembly strip 31.

[0034] The structure of the electric motor is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: The film roll is installed on the unwinding roller 21 to ensure that the film can be smoothly unwound from the unwinding roller 21. The motor driving the unwinding roller 21 and the take-up roller 22 is started, causing the film to move from the unwinding roller 21 to the take-up roller 22. During the movement of the film, the pressure rollers 25 symmetrically installed on the surface of the processing table 1 are used to fix and guide the position of the film, ensuring smooth delivery. When the film is delivered to the designated position, the hydraulic rod 23 is activated. The telescopic end of the hydraulic rod 23 drives the softening mechanism 24 to descend, so that the softening mechanism 24 contacts the surface of the film and softens it. After softening, the hydraulic rod 23 retracts, driving the softening mechanism 24 to rise and reset, waiting for the next softening operation. This realizes automated delivery and heating of the film, avoiding manual delivery, ensuring uniform heating of the film, and further improving product quality.

[0036] When cleaning the adhesive film surface is required, since the support plate 27 is in the horizontal position when not being cleaned, the operator first pulls out the positioning pin 210. At this time, the positioning pin 210 overcomes the elastic force of the return spring 211 and is pulled out from the insertion hole on the surface of the processing table 1. Since the surface of the movable rod 26 is fitted with a torsion spring 29, under the action of the torsion spring 29, the movable rod 26 rotates, driving the support plate 27 and the cleaning wheel 28 to rotate to a position perpendicular to the surface of the processing table 1. Then, the positioning pin 210 is released, and under the action of the return spring 211, the positioning pin 210 is inserted into the insertion hole on the surface of the processing table 1 for vertical positioning, thereby achieving the positioning of the support plate 27. The surface of the cleaning wheel 28 is fitted with a cleaning cloth. When the cleaning wheel 28 is in a position perpendicular to the surface of the processing table 1, the cleaning cloth contacts the surface of the adhesive film. At this time, the driving film continues to move. During the movement of the film, the cleaning cloth cleans the impurities and adhesive residues adhering to the surface of the film. This enables the film to be cleaned before heating and softening, thus preventing impurities and adhesive residues from affecting the heating and softening effect.

[0037] When the cleaning cloth needs to be replaced after a period of use, unscrew the bolt 33 on the connecting strip 32. The bolt 33 will unscrew from the threaded holes on the connecting strip 32 and the disassembly strip 31. Then, pull the disassembly strip 31 out of the slot on the surface of the connecting strip 32, thereby removing the cleaning wheel 28 with the cleaning cloth installed. After replacing the cleaning cloth or cleaning wheel 28, insert the disassembly strip 31 into the slot of the connecting strip 32, and then tighten the bolt 33 to fix it. This completes the replacement of the cleaning wheel 28, preventing a large amount of dust and impurities from adhering to the cleaning cloth and affecting the cleaning effect on the adhesive film.

[0038] It should be noted that the softening mechanism 24 consists of a heating element and a pressure plate. The heating element can be a resistance wire, heating tube, etc., and is installed inside or near the pressure plate. During operation, the hydraulic rod 23 pushes the pressure plate down, causing the pressure plate to contact the adhesive film. The heating element heats the pressure plate to a suitable temperature, softening the adhesive film through heat transfer.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
