Description

Dust removal roller device

The present invention relates to a dust removing roller device; in particular, to a drum rotation and a feeding of a dust removing belt, and a technician who moves the cutting knife on a reference axis to form a plurality of oblique cutting lines and a dust removing segment winding roller; .

Referring to FIG. 1, the printed circuit board 90 or the like is passed between the rotating rollers 91 made of synthetic rubber, the rotating roller 91 is adhered to the surface of the circuit board 90, and the dust is applied to the rotating roller 91 by the dust removing roller 92. Dust, which is a known device or method, that achieves dust removal. For example, Taiwan No. 89291411 "Printed Circuit Board Surface Cleaner", No. 97111829 "Manufacturing Method of Dust Removal Roller" and No. 92210496 "Circuit Board Cleaner Structure Improvement" Patent Case provide typical implementation. example.

In practice, the surface of the dust removing roller is wound with a plurality of adhesive tapes, and each adhesive tape is structured on two surfaces of a base material (for example, paper, plastic film, etc.), and an adhesive layer and a release layer are respectively disposed. It is constructed and then wound on a drum. When the dust removing roller or the adhesive layer adheres to more dust, the person can tear off an adhesive tape and let the clean next adhesive tape perform the work of adhering the dust on the rotating roller.

A related problem in the construction and manufacture of such a dust removing roller is that when the adhesive tape is wound on the roller, a gap is formed between the cutting lines of each adhesive tape due to the tension formed by the winding or winding of the adhesive tape. The gaps make it impossible for each adhesive tape to abut each other.

For example, the case of "manufacturing method of dust removing drum" No. 97111829 is a structure in which an adhesive tape is cut into a long-shaped segment; in order to allow each adhesive tape to be wound in a continuous and tight process during the cutting operation, On the drum, the non-cut portions or widths must be reserved on both sides of the adhesive tape, and each of the adhesive tapes can be continuously wound on the drum by the portions which the cutters cannot cut. Then, a dust removing roller is completed by cutting the both ends of the drum and the non-cut portions of the adhesive tape wound at both ends of the drum through a slitter slitter.

As those skilled in the art know, when the roller pulls the non-cutting portion on both sides of the adhesive tape to move and wind, a force is generated; at this time, the laterally cut portion of the cutter is pulled by the tension, so that the front and the rear are adjacent. There is a gap between the two adhesive strips, and each of the adhesive strips cannot obtain a positively adjacent pattern; this affects the smoothness and regularity of the adhesive tape wound on the roller, and the ability of the subsequent dust removing roller to adhere to dust or dust removal. The cooperation of the drum with the above-described rotating roller 91 becomes unsatisfactory, and this situation is not desirable.

Typically, these references show the use and structural design of the dusting drum or adhesive tape and its associated components. If the re-design considers the structure of the dust-removing roller and related components, as well as the above-mentioned application, making it different from the conventional one, it will change its use type, increase its structure and ease of manufacturing work, and be different from Old law. For example, in the process of cutting, the adhesive tape is cut in the cutting process, because the effect of the tension makes it impossible for each adhesive tape to obtain a true abutment, and is minimized as much as possible. The progress of the cutting operation; or further improvement of the old method affects the smoothness and regularity of the adhesive tape wound on the drum, resulting in the unsatisfactory ability of the subsequent dust removing roller to adhere to the dust, the person not easily peeling off the used adhesive tape or the repeated peeling Adhesive belt and so on. None of these topics have been specifically taught or disclosed in the above references.

Therefore, the main purpose of the present invention is to provide a dust removing roller device which provides a dust collecting structure configuration and a cutting operation which is more desirable; and includes a combination of a drum and a plurality of dust removing segments disposed on the drum. A feeding operation of the dust removing belt is provided, and the cutting knife is moved on a reference shaft to form a plurality of oblique cutting lines and front and rear adjacent dust removing segments, which are continuously wound on the drum. And, according to the position of the dust-removing segment wound on the circumference of the drum, the oblique cutting line of the latter dust-removing segment and the oblique cutting line of the preceding dust-removing segment are at different positions to form a dust-removing roller assembly; Belt structure and situations where they cannot be mutually adjacent.

Fig. 6 is a schematic view showing a modified embodiment of the present invention; depicting a case where a reserved portion or a width is formed on both sides of the dust removing belt.

Referring to Figures 2, 3, 4 and 5, the dust removing roller device of the present invention comprises a combination of a drum 10 and a plurality of dust removing segments disposed on the drum 10. In an embodiment, a paper, a plastic film, or the like is used to form a continuous type of sheet substrate; on both surfaces of the substrate, an adhesive layer and a release layer are respectively disposed (not shown), and A dust removing belt 20 is formed. Then, the cutter 30 is moved on a reference axis X, and the dust belt 20 is cut. A plurality of obliquely cutting lines and dust removing segments are formed, and the dust removing segments are wound around the drum 10 to constitute a dust removing roller assembly 100.

Hereinafter, for convenience of explanation, two adjacent dust removing segments are respectively defined as the former dust removing segment 21 (or the first dust removing segment) and the latter dusting, with reference to the direction of winding or approaching the drum 10 as a reference. Fragment 22 (or a second dusting segment). And, the reference axis X may select a lateral reference axis (ie, perpendicular to the feed or delivery direction of the dust removing belt 20) or an oblique reference axis.

Figures 2, 3, 4 and 5 show an oblique cut line having a width of 0.01 mm to 0.03 mm between the dust removing belt 20 or each dust removing section, so that each dust removing section forms a geometric outline of a parallelogram. For example, the oblique cutting line 23 of the preceding dust removing section 21 and the oblique cutting line 24 of the latter dust removing section 22 are obliquely cut. The first dust removing segment 21, the latter dust removing segment 22 further includes side edges 25, 26, respectively; and the oblique cutting line 23 (or 24) extends obliquely from the side edge 25 toward the other side edge 26, defining the front A dust removing segment 21 (or the latter dust removing segment 22) is in the form of a parallelogram.

In a possible embodiment, it is assumed that every 10 dust removing segments (having the same length) are a group (or a first group of dust removing segments), and when wound around the drum 10, the overall diameter of the drum 10 is gradually increased; The position of the oblique cutting line 24 of one dust removing section 22 on the drum 10 (circumference) is retracted from the position of the oblique cutting line 23 of the preceding dust removing section 21 on the drum 10 (circumference), so that the latter dust removing section 22 The oblique cutting line 24 and the oblique cutting line 23 of the preceding dust removing section 21 are staggered or positioned at different positions on the circumference of the drum 10. This helps the diagonal cutting line 24 of the latter dust removing section 22 and the oblique direction of the preceding dust removing section 21 after the dust removing drum assembly 100 has more dust adhered to the outer dust removing section or the latter dust removing section 22. The cutting line 23 is in different positions, and the person can simply and directly tear off the dusting sheet wound around the periphery of the drum 10. The segment (or the latter dust removing segment 22) does not repeatedly peel off the dust-removing segment (or the previous dust-removing segment 21) wound around the inner circumference; the conventional person is not easy to peel off the used adhesive tape or the repeated peeling adhesive tape occurs. situation.

It can be understood that, according to the above embodiment, the length of the second group of dust removing segments can be made larger than the length of the first group of dust removing segments, and sequentially wound on the drum 10.

Referring to Figures 2 and 3 again, the dust removing roller device according to the present invention includes a manufacturing method; the method includes:

The program (A) provides a feeding operation of the dust removing belt 20; the feeding operation of the dust removing belt 20 is distributed toward the rotating drum 10, and the dust removing belt 20 can be wound around the drum 10.

Program (B) provides a cutting operation. On the feeding path of the dust removing belt 20, a cutter 30 is provided; the cutter 30 moves on the reference axis X, and a plurality of oblique cutting lines are cut on the dust removing belt 20 to form a plurality of front and rear Adjacent dust removing segments (for example, the aforementioned first dust removing segment 21 and the latter dust removing segment 22) are continuously wound around the drum 10 to constitute a dust removing drum assembly 100.

It must be noted that, initially, when the cutter 30 is moved laterally or obliquely along the reference axis X, when the dust belt 20 is cut, most of the area of the previous dust removing segment 21 (for example, the intermediate portion 28 and/or the rear portion region 29) The latter dust removing section 22 is connected; therefore, as the front end region 27 of the preceding dust removing section 21 is wound around the drum 10, the rotating drum 10 causes the preceding dust removing section 21 to move, and then one dust removing section 22 continues to move toward the drum 10. Or feed. At the same time, as the drum 10 is rotated to drive the dust removing belt 20 to feed, the cutter 30 continuously cuts the oblique cutting line (for example, 23 or 24) on the dust removing belt 20.

When the cutter 30 reaches the intermediate portion 28 of the preceding dust removing section 21 (or the previous dust removing section 21 is completely cut), the front end region 27 (or the intermediate portion 28) of the latter dust removing section 22 has been taken in and wound up. On the drum 10; that is, the latter dust removal The segment 22 can be smoothly wound on the drum 10 by the rotating drum 10 in cooperation with the previous dust removing segment 21, and the cutting line of each adjacent dust removing segment is obliquely extended. The old method is used in the process of cutting the dust belt or the adhesive tape. Because the tension is pulled, a gap is formed between the two adhesive tapes adjacent to the front and the back, and each adhesive tape cannot be surely adjacent to each other, which affects the progress of the cutting operation and the like. .

Referring to FIG. 6, in a modified embodiment, the non-cutting portion 35 (or the non-cutting width) is reserved on both sides of the dust removing belt 20; the set position of the cutter 30 does not cut the non-cutting portion 35. By means of these non-cutting portions 35, the feeding or dispensing of the dust removing belt 20 is assisted, so that each dust removing segment is continuously wound on the drum 10, and then the both ends of the drum 10 are cut and wound with a boring cutter. The dust removing drum assembly 100 is completed at the non-cutting portion 35 of the dust removing belt 20 at both ends of the drum 10.

Typically, the dust-removing roller device and the manufacturing method have the following considerations and advantages in comparison with the old method under the condition of being simple and convenient to operate:

1. The structure of the drum 10, the dust removing belt 20 and the related components has been redesigned to make it different from the conventional user and to change its use and operation type, which is different from the old method. For example, the drum 10 rotates to drive the dust removing belt 20 to be distributed toward the drum 10, and the matching cutter 30 moves laterally or obliquely on the reference axis X to form a plurality of oblique cutting lines 23 and 24 parallel to each other, in cooperation with the dust removing belt 20. The sides 25, 26 define a portion of the adjacent first dusting segment 21, the latter dusting segment 22 to form a geometrical contour of the parallelogram, and are significantly different from the conventional structure.

2. Especially compared with the old method, the dust removing belt 20 is smoothly fed or distributed during the cutting process, which improves the cutting process of the old method in the dust removing belt or the adhesive tape, and each adhesive tape cannot be surely adjacent to each other. , affecting the progress of the cutting operation, or the occurrence of repeated peeling of the adhesive tape or dust belt, and also significant improvement.

Therefore, this creation department provides an effective dust-removing roller device, which has different spatial patterns than the conventional ones, and has the advantages unmatched in the old law. It shows considerable progress and is fully in line with the new patents. Essentials.

However, the above is only a feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the creative patent. .
