Description

  The present invention relates to an etching processed product manufactured by etching from a metal plate material that is a processed material, and in particular, facilitates separation by a trimming line portion from the metal plate material that is a processed material such as a shadow mask product and a lead frame product. The present invention relates to a method and an apparatus.

In recent years, shadow masks for color TVs (CRTs) have been mass-produced as the amount of use has increased, and depending on the purpose of use, there has been a demand for finer and larger sizes.
Such shadow masks are generally produced in an integrated line using a metal plate 600 continuous in a strip shape as a material (FIG. 4 (a)). While being moved intermittently, plate making and etching are performed so that the outer peripheral portion of the product portion (referred to as a shadow mask) 611 of each shadow mask is held by the metal plate 600 and the shadow mask 611 is attached to the metal plate 600. The outer shape is processed with the surface facing. (Fig. 4 (b))
Thereafter, as shown in FIG. 4C, the metal plate 600 is once cut, and each shadow mask 611 is separated from the cut metal sheets 610 and 610A (FIG. 4D). A trimming method (offline) Method) is generally adopted.
The metal sheet cut from the metal plate 600 has a state in which an unnecessary metal plate portion 612 is attached to the outside of one shadow mask (single-sided), as shown in FIG. As shown in FIGS. 4C and 4A, a plurality of the sheets shown in FIGS. 4C and 4B are formed into one sheet.
As this trimming method, an outer peripheral line (hereinafter also referred to as a trimming line) of a shadow mask in which a half-etched portion and / or a through-hole portion is formed on the outer periphery of the shadow mask by etching is provided in advance. The first method of pressing the product part of the mask mask and lifting the unnecessary metal plate part 612 and separating it from the product part with a holding mold suitable for the The 2nd method etc. which bent and separated the metal plate part 612 up and down were taken.
The trimming by the first method and the second method is not incorporated in the etching processing line, but is also called an off-line trimming method. The apparatus used in the second method is used in the etching processing line. It is also called an off-line trimming device or off-line stripper, not a built-in one. Also, hereinafter, a trimming method built into an etching processing line is called an in-line trimming method.

However, these methods require holding dies for each product type. In particular, in the second method using the apparatus, there is a problem in that the cost of the die is high and it takes time to change the setup.
Also, there is a problem that trimming takes time and is not efficient.
For this reason, in-line trimming processes have been attempted in order to improve the productivity of trimming work and reduce costs.
For example, there is a method of separating a product part and an unnecessary part by peeling off without causing metal trimming to weaken the trimming line part as described in JP-A-2002-370197 (Patent Document 1). And proposed by the present applicant.
Here, “extraction” refers to a method in which when an unnecessary portion outside the product portion is pulled and broken, the portion is broken while being pulled outward from the product portion.
This in-line trimming method has various problems when the product size, imposition, product type, etc. are different, and has not yet been put to practical use in the etching processing line.
JP 2002-370197 A

Further, as described in Japanese Patent Application Laid-Open No. 2001-266741 (Patent Document 2) filed by the present applicant shown in FIG. 3, the trimming line portion is weakened by in-line connection to the trimming line portion. The applicant of the present application has proposed an in-line trimming method in which a product portion and an unnecessary portion are pulled apart from each other after being made to run.
In the in-line trimming method shown in FIG. 3, a metal work 420 provided with a product and a trimming line portion is formed by forming a path of a concavo-convex metal work 420 that is vertically moved with respect to the transport direction by two transport belts 451 and 456. Is conveyed while being sandwiched between two upper and lower conveyor belts 451 and 456, passed through the corrugated metal workpiece passage, and the metal workpiece is bent corresponding to the corrugated metal workpiece passage shape to the trimming line portion. Thus, the product 410 and the unnecessary part 420 are separated.
Here, the metal workpiece 420 is formed by etching a metal sheet that is continuous in a strip shape, and includes a product and a half-etched portion and a through-hole portion around the entire product. And a trimming line portion for integrally connecting the two.
However, in this method, the metal workpiece 420 provided with the product and the trimming line portion is conveyed while being sandwiched between the upper and lower two conveyor belts 451 and 456, and passes through the path of the uneven metal workpiece. The trimming line portion cannot give sufficient metal fatigue, which is a problem.
When a belt is stretched between the upper and lower rolls 453 and 458 and the sheet is passed in a nipped state, the belt proceeds like a belt and it is difficult to reliably weaken the trimming line portion.
In FIG. 3, B0 is a separation part that pulls and separates the unnecessary part and the product part.
Japanese Patent Laid-Open No. 2001-266741 In addition, Japanese Patent Laid-Open No. 2001-266742 (Patent Document 3) discloses in-line trimming that separates a product portion from an unnecessary portion after metal trimming is applied to weaken the trimming line portion. In the method, when separating the product and the unnecessary part, a method of facilitating separation by attracting a metal workpiece with a magnet has been proposed. In the case of this method as well, there is a problem that sufficient metal fatigue cannot be given to the trimming line portion of the metal workpiece basically the same as that described in Japanese Patent Application Laid-Open No. 2001-266741. JP 2001-266742 A

In addition, there is a method of bending the trimming line part of the metal workpiece by using only a roll and making the trimming line part fatigued and weakened, but in this case, if the angle of the wavy undulation is applied, the trimming is performed. Although the line portion weakens, the trimming line portion breaks, and the product portion directly contacts the roll, resulting in poor quality.
Further, there is a problem that the degree of weakening of the trimming line portion (the degree of metal fatigue) changes in the front portion and the rear portion of the imposition.

In addition, as a pre-processing for trimming for separating the product portion and the unnecessary portion, a method for facilitating the metal fatigue in the trimming line portion so that the trimming can be easily performed is disclosed in Japanese Patent Application No. 2004-178929. Has been proposed.
In other words, this method is an improvement of the method for promoting metal fatigue of the trimming line portion described in Japanese Patent Application Laid-Open No. 2001-266741 (Patent Document 2). The metal workpiece passes through the metal workpiece passage that repeats irregularities in the direction perpendicular to the metal workpiece conveyance direction, with the gap between the strips of the metal workpiece, and promotes metal fatigue at the trimming line. However, at the concave or convex portion of the passage, a gap is generated between the metal workpiece and the belt on the side where the metal workpiece protrudes in a direction perpendicular to the conveyance direction, and the metal with respect to the conveyance direction is further generated. The bending displacement amount of the workpiece and the bending angle of each belt are controlled so that the metal workpiece passes through the passage.
However, even in this method for promoting the metal fatigue of the trimming line portion, the metal work proceeds as a belt, and there is a problem that the bending effect in the trimming line portion cannot be sufficiently obtained and the metal fatigue is not sufficiently promoted.

As described above, in recent years, in the etching process of metals such as shadow masks, in-line trimming methods are required from the viewpoint of productivity and cost. An in-line trimming method for pulling a product part and an unnecessary part so as to separate them after applying metal fatigue to the line part to weaken it is disclosed in Japanese Patent Application Laid-Open No. 2001-266741 and Japanese Patent Application Laid-Open No. 2001-2001. Although it has been proposed as described in Japanese Patent Publication No. -266742, there is a problem in that the trimming line portion described therein cannot provide sufficient metal fatigue to the trimming line portion of the metal workpiece. We had this, and this correspondence was demanded.
And the method of promoting metal fatigue in the trimming line portion proposed in Japanese Patent Application No. 2004-178929 also proceeds as a belt for the metal workpiece, and in the practical level, the bending effect in the trimming line portion cannot be sufficiently obtained, There has been a problem that metal fatigue is not sufficiently promoted, and a countermeasure has been demanded.
The present invention is corresponding to this, and can provide sufficient metal fatigue to the trimming line portion of the metal workpiece, and does not damage the product quality, and the metal fatigue promoting device for the trimming line portion and the metal fatigue of the trimming line portion.

In addition, a metal fatigue promoting passage 140 is provided at the groove line portion, and further, floating between the adjacent rolls (the first rotating roll 130 and the second rotating roll 135) from the belt 120 at the trimming line portion of the metal workpiece 180 is suppressed. A magnet 190 is provided as a metal work control means for controlling the metal work 180 along the belt.
As shown in FIG. 1C, the metal workpiece 180 is guided by the plurality of first rotating rolls 130 and the plurality of second rotating rolls 135 together with the belt 120, and is orthogonal to the conveying direction of the metal workpiece. The metal fatigue in the trimming line portion of the metal workpiece 180 is promoted while meandering repeatedly repeating up and down (unevenness) in the vertical direction.

When passing through the passage 140, the magnet 190 is disposed between the adjacent rolls as a metal work control means for controlling the metal work along the belt, whereby the trimming line portion between the adjacent rolls is arranged. Suppresses metal fatigue from lifting from the belt.
In this way, it is possible to sufficiently promote metal fatigue in the trimming line portion 185 without receiving quality damage due to the floating from the belt in the trimming line portion 185.
Here, a plurality of elements arranged in a zigzag manner so as to repeat unevenness in the vertical direction perpendicular to the conveying direction of the metal workpiece 180 along the conveying direction of the metal workpiece 180 (the direction from the arrow 1 to the arrow 2). The metal work is transported along one side of the belt that is guided by the first rotating roll 130 and the second rotating roll 135 and advances in the transport direction of the metal work 180. And, in order to promote metal fatigue in the trimming line part, it is possible to promote sufficient metal fatigue compared to the form that conveys the belt along both sides of the conventional metal workpiece and promotes metal fatigue, Further, by providing the magnet 190 as the metal workpiece control means, quality damage can be prevented.

This example is one example, and the present invention is not limited to this example.
For example, although this example is based on the premise of horizontal conveyance of a metal workpiece, it is needless to say that the same function and effect can be obtained even if the workpiece is not horizontal.
In this example, the plurality of first rotating rolls 130 and the plurality of second rotating rolls 135 are arranged horizontally, parallel to each other, and have a constant interval. A form in which the gap between the rotary roll 135 and the conveyance direction has a slight gradient is also possible.
Moreover, the form which arrange | positions a suction cleaner in the contact part with the metal workpiece 180 of the belt 120 can also be mentioned.
