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 workpiece 420 provided with a product and a trimming line portion is formed by forming a path of a concave-convex metal workpiece 420 that moves up and down in the conveyance direction with two upper and lower conveyance belts 451 and 452. Is conveyed between the upper and lower conveyor belts 451 and 452, and is passed through the corrugated metal workpiece path, and the metal workpiece is bent corresponding to the corrugated metal workpiece path 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 452, 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 There is also a method of using only a roll to bend a trimming line portion of a metal workpiece to make the trimming line portion fatigue and weaken the metal, but in this case, a wavy undulation If the angle is set, the trimming line portion weakens, but 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.

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 various proposals have been made as described in Japanese Patent Laid-Open No. -266742, in the in-line trimming method described in Japanese Patent Laid-Open No. 2001-266741 and Japanese Patent Laid-Open No. 2001-266742, a trimming line portion of a metal workpiece is used.

The trimming line part metal fatigue promoting device in this example is made by etching a continuous metal sheet in a strip shape, and consists of a shadow mask as a product, and a half-etched part and a through-hole part around the entire product. Trimming line part that integrally connects the product and unnecessary part is provided at the part, and metal fatigue is advanced in the trimming line part before trimming to separate the product at the trimming line part from the continuous metal work in a strip shape It is a metal fatigue promoting device for trimming lines that makes it easy to separate the product and the unnecessary part, and conveys the metal workpiece horizontally.
Then, as shown in FIG. 1B, a metal workpiece path in which unevenness is repeated in a direction orthogonal to the conveying direction of the metal workpiece 180, with the path between the first belt 120 and the second belt 125. And the metal work passes through the passage to promote the metal fatigue of the trimming line portion of the metal work.
When passing through the passage, the metal workpiece 180 is repeatedly bent, thereby promoting the metal fatigue of the trimming line portion of the metal workpiece.
In FIG. 1 (a), although the metal workpiece is not shown in the drawing, it is conveyed between the first belt 120 and the second belt 125 in the direction of the arrow 1 to the arrow 2, and the metal fatigue of the trimming line portion is observed. Promotion work is done.
The direction from arrow 1 to arrow 2 is the transport direction.
In the metal fatigue accelerating device of the trimming line portion of this example, the first belt 120 includes a plurality of first rotating rolls 130 arranged on the opposite side of the metal work 180 to be conveyed along the conveyance direction. The first belt 120 is disposed between the adjacent first rotating rolls 130 and is positioned closer to the metal workpiece 180 than the position where the adjacent first rotating rolls are linearly connected. It is supported by a push-in rotary roll 140 that is pushed into the 180 side, and its position is controlled.
The second belt 125 is arranged along the conveying direction so that the opposite side of the metal workpiece 180 to be conveyed is paired with each first rotating roll 130 and has a predetermined distance. Supported by the plurality of second rotary rolls 135 and pushed by the respective push rotary rolls 140 from the side of the metal work 180 between the adjacent second rotary rolls 135 via the metal work, The position is controlled.
A gap 190 is generated between the first belt 120 and the metal workpiece 180 in each pair of the first rotary roll 130 and the second rotary roll 135, and the metal workpiece 180 of the conveyance direction is By controlling the amount of bending displacement and the bending angle of each belt, the metal workpiece 180 passes through the passage.

Further, by changing the angle θ1, θ2, and θ3 of the belt at the position where the upper gap 190 is generated, the product portion becomes the first belt. It is possible to prevent contact with the (first rotating roll side), and eventually, the metal fatigue of the trimming line portion can be reliably and stably promoted and weakened.

In the metal fatigue accelerating device of the trimming line portion of this example, each first rotating roll 130 is supported by a bearing portion (not shown) held by the frame 111 and rotates. The second rotary roll 135 is supported by a bearing portion (not shown) held by the frame 112 and rotates. Both the first rotary roll 130 and the second rotary roll 135 are horizontal along the transport direction. Is arranged.
In the metal fatigue accelerating device of the trimming line portion of this example, the positions of the frames 111 and 112 are fixed. In this state, the first rotary roll 130 and the second rotary roll 135 of each pair are predetermined. And a distance between each adjacent first rotary roll 130 (between each adjacent second rotary roll 135) is also determined in advance.
Each push rotary roll 140 is supported by a bearing portion (not shown) supported by the frame 113 and rotates, and is disposed horizontally along the transport direction.
And the position of each pushing rotary roll 140 can adjust and change the vertical direction position by the position adjustment parts 113a and 113b (of the pushing rotary roll).
Although not shown in FIG. 1 (a), an adjustment unit for moving the push-in rotary roll 140 in the horizontal direction is further provided, whereby each angle θ1, θ2, It is possible to take θ3 in a wide range.

The second belt tension roll unit 150a fixes the rotary rolls 152a and 153a and performs the belt tension roll by moving the rotary movable roll 151a in the vertical direction.
Thereby, the tension of the first belt 120 and the second belt 125 can be adjusted when the amount of pressing by the pressing rotary roll is changed or when the pitch of the first rotary roll (the pitch of the second rotary roll) is changed. .

The drive unit 160 is for driving the first belt 120 and the second belt 125, and transmits the rotation from the motor 164 to the drive shaft 161 a, and the rotation of the drive shaft 161 a is transmitted via the chain 162. Is transmitted to the drive shaft 161b.
Then, the first belt 120 is driven by the rotational force of the drive shaft 161a so that the positions of the rotary rolls 163a and 163b are controlled to bring the first belt 120 into contact with the drive shaft 161a.
Then, the second belt 125 is driven by the rotational force of the drive shaft 161b such that the positions of the rotary rolls 163c and 163d are controlled so that the second belt 120 contacts the drive shaft 161b.
As a result, the first belt and the second belt can run at the same speed, and by making this speed coincide with the conveying speed of the metal workpiece, it is possible to promote metal fatigue without causing scratches. .

This example is one example, and the present invention is not limited to this example.
For example, this example is premised on the horizontal conveyance of the metal workpiece, but it goes without saying that the same effect can be obtained even if the workpiece is not horizontal.
In addition, by arranging a suction cleaner at the contact portion of the first belt 120 and the second belt 125 with the metal workpiece 180, it is possible to eliminate the influence of the generation of metal powder.
