Description

Technical Field

[0001] This utility model belongs to the technical field of UV protective film production equipment, specifically relating to a UV protective film slitting and winding device. Background Technology

[0002] UV protective films generally consist of a release film, a UV anti-adhesion layer, and a base film. They are widely used in the semiconductor and optical instrument industries, such as semiconductor wafer dicing and grinding. During product manufacturing, the UV protective film, after removing the release film, can be used to bond and fix the processed materials, providing excellent physical protection. After processing, UV radiation instantly reduces the adhesive strength of the mold material, allowing the mold material to be easily peeled off from the bonded material without affecting its performance and leaving no residue, facilitating subsequent processing. To adapt to different processing needs and improve production efficiency, UV protective films, after coating and lamination, are often quite wide. Therefore, they need to be slit and wound by a slitting and winding device to simultaneously obtain smaller-width UV protective films, which are then wound into rolls. Thus, the reliability and operating efficiency of the slitting and winding device directly affect production efficiency and product quality.

[0003] Existing slitting and winding devices generally include a cutting roller, a positioning roller, at least two winding rollers, and multiple guide rollers. The cutting roller is equipped with several cutter discs, the positioning roller may be equipped with several cutting rings, and the winding roller may be equipped with several core rolls. When the film material passes through adjacent cutting rings, it is cut by the corresponding cutter discs. After that, the adjacent cut film materials are fed to the corresponding core rolls of different winding rollers under the separation and guidance of different guide rollers. As the winding rollers rotate, they are continuously wound into film rolls. This continuous feeding achieves slitting and winding. However, its drawback is that during the slitting and winding process of the film material, as the roll diameter increases, some areas may not have enough tension and flatness of the UV protective film due to factors such as thin protective film, insufficient tension, and equipment vibration. This affects the flat winding of the film roll and may even lead to slitting deviations or incomplete cutting, resulting in failures and losses, and affecting production efficiency and product quality.

The present invention provides a UV protective film slitting and winding device, which can quickly adjust the tension of the slit UV protective film and roll it up flat, which is beneficial to improving processing efficiency and product quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A UV protective film slitting and winding device includes a frame, a cutting roller, a positioning roller, and at least two winding rollers mounted on the frame, and a first drive mechanism. The cutting roller is provided with a plurality of cutter discs. The first drive mechanism is used to drive the winding rollers to rotate. At least one first guide roller and an adjustment mechanism are provided between the positioning roller and each winding roller. The adjustment mechanism includes a first bracket, a second bracket, and a second drive mechanism. The first bracket is provided with at least one second guide roller and a guide hole. A positioning shaft is provided between the second bracket and the first bracket. The second bracket is provided with at least one guide member and a third guide roller. The guide member cooperates with the guide hole.

[0010] In a preferred embodiment, the frame is provided with a third drive mechanism, which is used to drive the cutting roller to reciprocate relative to the positioning roller.

[0011] In a preferred embodiment, the frame is provided with an edge roller and a fourth drive mechanism, the fourth drive mechanism being used to drive the edge roller to rotate.

[0012] In a preferred embodiment, the edge roller and the take-up roller are located on opposite sides of the frame.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] To address the issue of insufficient tension and flatness of the UV protective film during the slitting and winding process, caused by factors such as thin protective film, insufficient tension, and equipment vibration, which affect the flat winding and slitting of film roll 11, as follows: Figures 1-3 The image shows a preferred embodiment of the UV protective film slitting and winding device of this utility model. The slitting and winding device includes a frame 1, a cutting roller 2, a positioning roller 3, and at least two winding rollers 4 mounted on the frame 1, and a first drive mechanism 5. The cutting roller 2 is provided with a plurality of cutter discs 6. The first drive mechanism 5 is used to drive the winding rollers 4 to rotate. At least one first guide roller 7 and an adjustment mechanism 8 are provided between the positioning roller 3 and each winding roller 4. The adjustment mechanism 8 includes a first bracket 81, a second bracket 82, and a second drive mechanism 83. The first bracket 81 is provided with at least one second guide roller 88 and a guide hole 84. A positioning shaft 85 is provided between the second bracket 82 and the first bracket 81. The second bracket 82 is provided with at least one guide member 86 and a third guide roller 87. The guide member 86 cooperates with the guide hole 84. The second drive mechanism 83 is used to drive the second bracket 82 to reciprocate around the positioning shaft 85 between the second guide roller 88 and the winding roller 4.

[0029] Taking the following as an example, the working principle of the above slitting and winding device includes: two take-up rollers 4, a first guide roller 7 between the positioning roller 3 and each take-up roller 4, a second guide roller 88 on the first support 81, two second guide rollers 88 on the second support 82, a feed roller 10 in front of the cutting roller 2 and the positioning roller 3, and a servo motor as the first drive mechanism 5.

[0030] like Figure 1 As shown, the UV protective film to be cut can enter between the cutting roller 2 and the positioning roller 3 along the feed roller 10. It can be cut by several blades 6 on the cutting roller 2. After cutting, the adjacent UV protective films with narrower widths pass around the corresponding first guide roller 7, second guide roller 88 and two third guide rollers 87 in sequence and are wound onto the take-up roller 4. The second support 82 is driven to deflect clockwise around the positioning shaft 85 by the second drive mechanism 83, so that the guide 86 can cooperate with the guide hole 84 for guidance. The last third guide roller 87 is quickly adjusted to approach the take-up roller 4. In this way, during the rotation of the corresponding take-up roller 4 driven by the first drive mechanism 5, the UV protective film is continuously fed and cut. The cut UV protective film is continuously transported to the corresponding take-up roller 4 and wound into individual film rolls 11. Since the third guide roller 87 can approach the take-up roller 4, it can smooth the UV protective film, making the winding more flat and reliable.

[0031] like Figure 2 and Figure 3 As shown, taking the guide hole 84 as a semi-circular hole and the guide member 86 as a rod that cooperates with the semi-circular hole as an example, as the slitting and winding proceeds, the diameter of the film roll 11 increases. The second support 82 can be driven by the second drive mechanism 83 to deflect counterclockwise around the positioning axis 85. At this time, the guide member 86 slides relative to the guide hole 84, which can further improve the adjustment stability. At the same time, the two third guide rollers 87 on the second support 82 deflect accordingly. However, the last third guide roller 87 is close to the winding roller 4 to maintain a smoothing effect, so that the third guide roller 87 is wound flat. During the process, the position of the third guide roller 87 can also be finely adjusted by the third drive mechanism 16 through the reciprocating deflection angle of the second support 82, thereby changing the distance between the third guide roller 87 and the second guide roller 88 and the winding roller 4, so as to quickly adjust the tightness of the UV protective film after slitting. This further improves the stability and reliability of the UV protective film slitting and winding, reduces the number of downtime due to failure, and is conducive to improving processing efficiency and product quality.

[0032] Furthermore, the frame 1 is provided with a horizontal oblong hole 13, and the first bracket 81 is provided with a bolt 14 that mates with the oblong hole 13; as Figure 3 As shown, for example, the frame 1 is provided with two oblong holes 13. The first bracket 81 can be adjusted by adjusting the horizontal mounting position of the two bolts 14 in the oblong holes 13, for example, as Figure 4As shown, when the core 12 of the film roll 11 is large, the installation position of the adjustment mechanism 8 can be adjusted by moving the first bracket 81 to the left relative to the frame 1, so that the deflection angle of the third guide roller can be close to the film roll 11 both initially and after winding. Similarly, when the core 12 of the film roll 11 is small, the installation position of the adjustment mechanism 8 can also be adjusted by moving the first bracket 81 to the right relative to the frame 1, thus increasing the applicability of the slitting and winding device.

[0033] Furthermore, the frame 1 is provided with a horizontal slide rail 15, and the first bracket 81 is slidably engaged with the horizontal slide rail 15; for example: Figure 3 and Figure 4 As shown, when adjusting the installation position of the first bracket 81, the bolt 14 can be loosened to push the first bracket 81 to slide relative to the horizontal slide rail 15 for quick adjustment, and then the bolt 14 can be tightened, which makes operation and debugging more convenient.

[0034] Furthermore, the second drive mechanism 83 includes a first cylinder 831, the tail end of which is hinged to a first bracket 81, and the cylinder rod of the first cylinder 831 is hinged to a second bracket 82; for example: Figure 3 As shown, a third bracket 89 is connected to the first bracket 81, and the first cylinder 831 is mounted on the third bracket 89 via a hinge. Figure 1 and Figure 2 As shown, the second bracket 82 can be pushed or pulled around the first bracket 81 by the lever extension and retraction of the first cylinder 831. During the process, the first cylinder 831 can be deflected accordingly by hinge. This structure is simple, easy to drive, and helps to reduce the space of the device.

[0035] Furthermore, the frame 1 is provided with a third drive mechanism 16, which is used to drive the cutting roller 2 to reciprocate relative to the positioning roller 3. For example, the third drive mechanism 16 includes an inclined second cylinder, which is mounted on the frame 1. The cylinder rod of the second cylinder is connected to the cutting roller 2. The cutting roller 2 is driven to reciprocate by the extension and retraction of the lever. In this way, the distance between the cutting roller 2 and the positioning roller 3 can be adjusted. Increasing the distance makes it easier to put in the UV protective film. When cutting, the distance can be reduced to meet the cutting requirements, making the operation more convenient.

[0036] Furthermore, the frame 1 is equipped with an edge material roller 17 and a fourth drive mechanism 9, the fourth drive mechanism 9 being used to drive the edge material roller 17 to rotate; for example: Figure 1 and Figure 2As shown, the fourth drive mechanism 9 includes a reducer 91, a first drive wheel 92, and a second drive wheel 93. Both the reducer 91 and the frame 1 are equipped with a third drive wheel 94. A first drive belt 95 is provided around the first drive wheel 92 and the third drive wheel 94, and a second drive belt 96 is provided around the first drive wheel 92 and the second drive wheel 93. The second drive wheel 93 is connected to the edge roller 17. The reducer 91 can drive the second drive wheel 93 to rotate via the third drive wheel 94 and the first drive belt 95, and then drive the second drive wheel 93 and the edge roller 17 to rotate via the second drive belt 96. The position of the first drive wheel 92 can be adjusted to tension the first drive belt 95. The rotational speed of the edge roller 17 can be further adjusted by adjusting the diameters of the first drive wheel 92 and the second drive wheel 93.

[0037] At least one first guide roller 7 can also be provided between the cutting roller 2 and the edge material roller 17. Then, the edge waste material cut off from both ends of the UV protective film can be wound onto the edge material roller 17 through the corresponding first guide roller 7 and collected as the edge material roller 17 rewinds. In this way, it is easier to rewind the waste material by adding the edge material roller 17.

[0038] Furthermore, the edge roller 17 and the take-up roller 4 are located on opposite sides of the frame 1, for example: Figure 1 and Figure 2 As shown, waste materials and UV protective film rolls 11 can be removed from both sides respectively, avoiding the impact on production operations caused by the device being too tall due to being set on the same side.

[0039] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. For example, a tension sensor is set during the UV protective film transportation process to further provide feedback control of the operation of the adjustment mechanism. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
