Abstract

This invention provides an effective method for trimming the surface of a perforated plate member, for example a reinforcing plate member mounting in a flexible printed circuit broad used in an electronic device. The method for trimming surface of a perforated plate member 11 with a circular hole 12 comprises first perforating a circular hole 22 on the lapping plate member 21 with similar shape and dimension as the perforated plate member 11; within a container 14, inserting a holding shaft 13 into the circular holes 12, 22 by juxtaposing alternately the perforated plate member 11 and the lapping plate member 21. Then, a high-pressure air is ejected from a nozzle 15 in a direction perpendicular to an axial direction of the holding shaft 13, and the nozzle 15 is swung in parallel to the axis of the holding shaft 13 so as to rotate the perforated plate member 11 and the lapping plate member 21. The surfaces of the perforated plate member 11 are thus trimmed by sliding abrasion of the adjacent lapping plate member 21.

[Prior Art] [0002] A cut-off portion of a plate-shaped cutting member obtained by a cutting means such as a perforation is formed with a blank in most cases. On the other hand, when the plate-shaped cutting member is brought into contact with the glass, the protrusion of the hair blank is generated to damage the other member, or the adhesion strength is lowered. Therefore, it is necessary to remove the blank of the cut portion in advance. Further, the surface finishing operation such as surface roughening for improving the adhesion strength is widely performed. [0003] In general, the surface finishing operation of the plate-shaped cutting member is carried out by means of grinding or the like. For example, as shown in Fig. 4, a y-rotating wiper wheel 2 is disposed above the conveyor belt J, and the holding rollers 3a, 3b are disposed at positions before and after the wiper wheel 2. The plate-shaped cutting member 4 is conveyed in the right direction in the drawing on the conveyance belt ,, and is held by the front and rear holding rollers 3a and 且 and is polished by the polishing wheel 2. However, when the size of the plate-shaped cutting member 4 is smaller than the interval between the front and rear holding rollers 3a and 3b, the rotating roller 2 is rotated like the two-point chain line of the figure. [0004] For example, in a flexible printed circuit board used in an electronic device, there are many small-sized members such as a reinforcing plate that follows the component assembly portion, and the plate-shaped cutting member having such a small size is It is difficult to perform the surface finishing work by the polishing means shown in the drawing. Therefore, for the 1271267 plate-shaped cutting member having a small size, the sheet-shaped cutting member is formed into a sheet shape without being completely separated, and the surface is trimmed by a polishing means, and then attached to the printed circuit board. This method of cutting is still in use today. [0005] However, in this method, even a small-sized reinforcing plate needs to have a sheet disposed at a position where the flexible printed circuit board is attached, so that a reinforcing plate material is formed to increase the efficiency and the efficiency is deteriorated. . Therefore, there is a need for a method for performing surface finishing work on a small size of a plate-shaped cutting member itself. ', Lu [0006] Regarding the surface finishing method of the plate-shaped cutting member, in addition to the above-mentioned polishing means, it is known that there is another type in which the blank surface of the part faces upward and is adsorbed and fixed on the magnet plate, and then rotated A wire brush is used to remove the blank (for example, refer to Patent Document 1). [0007] Further, it is known to provide a suction means for adsorbing and holding a sheet on a conveyor belt, and to transport the adsorbed sheet by a conveyor belt, and then remove the blank by a rotating de-hairing wheel (for example, refer to the patent document) 2). Further, it is understood that the surface side of the flexible thin plate-like body is formed as a weir portion, and the above-mentioned back surface side of the thin plate-like shape is sprayed intermittently in a pulsed manner, so that the aforementioned The grinding portion on the surface side of the thin plate-like body intermittently presses the blank generating portion of the workpiece to form a structure for removing the blank (for example, refer to Patent Document 3). [0009] In addition, it is possible to perform a surface finishing process by holding a workpiece by a holding means, inserting a workpiece into a rocking groove in which a processing material is accommodated and shaking, and maintaining a state in which the workpiece is held (for example, reference) Patent Document 4). 127,1267 [Patent Document 1] 曰 实用 实用 33 33 33 30 30 30 30 30 30 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 216 4] Japanese Patent Laid-Open No. Hei 9-85199 [Abstract] [Problems to be Solved by the Invention]

[0010] In the creation described in Patent Document 1, since the component is sucked into the magnet plate, even a small-sized plate-shaped cutting member can be surface-finished. However, if the plate-like member is not a body, it cannot be adsorbed by the magnet plate and the surface finishing operation cannot be performed. [0011] According to the invention described in Patent Document 2, since the adsorption means is provided on the carousel, it is difficult to remove the plate, and if the plate-shaped cut-off piece is reinforced by the hole, It is impossible to carry out adsorption retention. [0012] In the invention described in Patent Document 3, the flexible material is intermittently pressed by the high-pressure money pulsed old 恃 恃 [ ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Any fixed means will be blown away by the workpiece itself. In the invention in which the four objects are carried, the object to be treated is held. However, when the plate-shaped cutting member is flexible, the member is bent and has no effect. ί 对 由 由 由 由 由 由 由 由 由 由 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔Next, it is intended to perform a method of refining the slabs of a small-sized plate member such as a reinforcing plate of a component assembly portion of a flexible printed circuit board used in the electronic 7 1271 267. [Means for Solving the Problem] = 5] In order to achieve the above object, the inventors have invented a surface of a plate-shaped cutting member, which is a surface of a plate-shaped cutting member, and a plate-shaped cutting member obtained by a cutting means such as a perforation. In this case, the plate-like member is pre-opened as I-in-there is a shaft, and the plurality of plate-shaped cutting members are double-fitted in four's and then from the axial direction orthogonal to the aforementioned female : The air is shaken by swinging the nozzle and the holding shaft to rotate the plate-shaped cutting member, and the bake members are frictionally slid to perform surface finishing work. ' = axis = 2 pairs The circular hole opened by the plate-shaped cutting member - the axially orthogonal J-mouth of the holding shaft: = According to the high-pressure air, the surface of the cut-off member is rubbed and slid by the slab-shaped cutting member to perform the surface splicing [oon] t The surface of the trimming section of the trimming section - the surface of the plate-shaped cutting member of the seeding plate is corrected. == 裁= The plate-shaped grinding-cutting member and the plate-shaped grinding member of the pre-harvesting of the obtained grinding member are exhausted to == = 8 1271267 High-pressure air is ejected by a nozzle in a direction orthogonal to the axial direction of the holding shaft, and the nozzle is rotated in parallel with the axis of the holding shaft, whereby the plate-shaped cutting member and the plate-shaped polishing member are rotated. The surface trimming operation is performed by the frictional sliding of the adjacent plate-shaped cutting member and the plate-shaped polishing member. [0018] With this configuration, the circular hole of the plate-shaped cutting member and the circular hole of the plate-shaped polishing member are inserted and held. In the case of the shaft, the plate-shaped cutting member and the plate-shaped polishing member are alternately mounted in the container. The nozzle that is lifted in a direction orthogonal to the axial direction of the holding shaft is sprayed while being held around the holding shaft. High-pressure air is emitted, so the aforementioned plate-shaped cutting member and plate-like grinding The workpiece is rotated around the holding shaft by the high-pressure air, and the surface is trimmed by the frictional sliding of the adjacent plate-shaped cutting member and the plate-shaped polishing member. [0019] The invention described in claim 3 The surface finishing method of the plate-shaped cutting member according to the first aspect of the invention, wherein the plate-shaped cutting member or the plate is cut off by spraying high-pressure air from the side of the holding shaft. The member and the plate-like polishing member are rotated while the liquid or the liquid containing the abrasive grains is applied to the plate-shaped cutting member or the plate-shaped cutting member and the plate-shaped polishing member from above or to the side of the holding shaft. According to this configuration, the plate-shaped cutting member, the plate-shaped cutting member, and the plate-shaped polishing member are rotated from the side of the holding shaft to rotate the adjacent plate-shaped cutting member and the plate. The shape cutting member or the adjacent plate-shaped cutting member and the plate-shaped polishing member are frictionally slid to perform a surface finishing operation. However, each member generates heat due to frictional sliding, so that it is above the holding shaft or The liquid or the liquid containing the abrasive grains is sprayed sideways to enhance the lubrication or grinding efficiency of each member. The invention according to any one of the preceding claims, wherein the container is sealed as described in any one of claims 1 to 3 of the patent scope of the patent application No. In addition, the surface trimming method is connected to the dust collecting device, and the container (10) that accommodates the plate-shaped cutting member, the plate-shaped cutting structure, and the plate-shaped polishing member is slid. Dust or dust generated during surface finishing will not fly out of the grain. The dust collector can be efficiently collected to a designated location. [Effect of the Invention] [0^3] In the present invention, as described above, the plate-shaped cutting members adjacent to each other in the container or the adjacent plate-shaped cutting members and the plate-like polishing members are rotated around the holding shaft and The friction slides, so the surface finishing work can be performed in a short time. Further, since the plate-shaped cutting member is rotatably attached to the holding shaft, even in the case of a plate-shaped cutting member having a small size, it is possible to perform the removal of the cut portion or the roughening of the surface. Face finishing work. Moreover, by selecting the liquid to be sprayed in the container and the grinding member, the φ can be expanded. BEST MODE FOR CARRYING OUT THE INVENTION [0024] Hereinafter, a surface finishing method of a plate-shaped cutting member according to the present invention will be described by way of a preferred embodiment. In the method of performing a face trimming operation such as deburring or surface roughening on a cut portion of a plate-shaped cutting member obtained by a cutting means such as a punching, the present invention provides an effective effect on, for example, being followed by A flexible printed circuit board used in an electronic device, 10 1271267, a reinforcing plate of an assembly unit, or the like, which has a small-sized plate-shaped cutting member, is subjected to surface finishing, and is achieved by the following method, that is, A circular hole is formed in advance in the plate-shaped cutting member, and the circular hole is inserted into the holding shaft to overlap the plurality of plate-shaped cutting members, and is placed in the container, and is orthogonal to the axial direction of the holding shaft. The high-pressure air is jetted by the nozzle, and the nozzle is oscillated in parallel with the axis of the holding shaft, whereby the plate-shaped cutting member is rotated, and the surface-finishing operation is performed by friction sliding between the adjacent plate-shaped cutting members.

= sheet, the breaking members η, u, etc., and the nozzles 15 mounted on the container til high-voltage line are slidably attached to the guide shafts disposed in parallel with the holding shaft 13 16. [_] Next, the high-rise air is sprayed from the nozzle 15 orthogonal to the drawing direction of the holding shaft 13 as shown in the figure, and the plate is formed by shaking the front and the front row. The cutting member U is towed and the flat members u and u are slipped by each other. Further, above or to the side of the holding shaft 13,

A nozzle 17 for liquid spray is provided at a position where the nozzle 15 is rocked. Here, if the plate-shaped cutting members n' 1; 1 can be surface-trimmed by friction sliding, the above-described configuration can be performed. However, the material of the plate-shaped cutting member 11 may be surface-finished. Poor efficiency occurs. In this case, the circular hole 22 may be previously formed on one side of the plate-shaped polishing member 21 having a shape dimension f similar to the shape of the plate-shaped cutting member n, and the circle of the plate-shaped cutting member may be circulated. The hole 12 and the circular hole 22 of the plate-shaped polishing member 21 are inserted into the holding shaft 13, and the plate-shaped cutting member 丨1 and the plate-shaped polishing member 21 are alternately mounted in the container 14.

Further, the shape of the plate-shaped cutting member 丨丨 and the plate-like polishing member 21 which can effectively function in the present invention is preferably a rectangle having a length of 15 mm and a width of 9 mm or a shape similar thereto. In addition, the f-shaped position of the circular hole 12 and the circular hole 22 is the length of about 1/3 to 1/5 of the longitudinal end portion of the slab-shaped polishing member 21 and the longitudinal direction of the plate-shaped polishing member 21, because the most efficient effect can be imparted. The rotation is better. Further, the inner holes of the circular hole 12 and the circular hole 22 are each set to be larger than the outer diameter of the holding shaft 13 to form a plate-shaped cutting member η and a plate-like grinding member 21 through which the holding shaft 13 is inserted. The rotation can be performed centering on the holding shaft 13. In the case of the slab-shaped cutting member 11 and the plate-shaped polishing member, the fourth article is used. The miscellaneous _ _ 11 and the slab overlap each other and install the jigs 18 and 18 in the vicinity of the holding shaft 13 which is completed to prevent the plate-shaped cutting member n from running out. The material of the plate-shaped polishing member 21 is soft depending on the material, but it is preferably as smooth as possible and does not deform. Further, if the minus-member η and the plate-like grinding 12 127, 1267 (b) 3 times -, the member weight is not = she is fixed to the r and the plate-like grinding member 21 is mounted: :=== =] in the container 14 is sealed Thereafter, as in the front 15, around the holding shaft 13, while shaking, the side is sprayed, and the tearing is performed on the scales. Because the guide shaft f6 is cut 13 _ can be gamma-free plate-like member Π and the plate-like grinding member 21 sprays high air so that the position of each member LH f sealing nozzle 15 is as shown in Fig. 3, and is cut by a distance plate The portion of the distance between the fracture member 11 or the plate-like abrasive member 21 at the lower end in the longitudinal direction is the target, and the range of the angle d shown by the symbols 15c and 15d is set as the formula 1. Further, if the distance is 45 to 10 mm and the angle d At about 5 o'clock, it is preferable because the most efficient rotation can be imparted. [0033] Further, the injected air is discharged from the discharge port 19. This discharge port 19 can also be connected to a dust collecting device (not shown). Connecting, and when it is connected to the dust collecting device, the dust or dust generated during the surface finishing work by friction sliding The enamel and the like do not scatter outside the container, and the dust collecting device can be used for the purpose of collecting dust in the dust collector 13 127, 1267 1 . [0034] Here, depending on the material of the plate-shaped cutting member 11 There is a problem due to the heat generated by the frictional sliding. In addition, in order to improve the lubrication or the polishing efficiency, it is also good to add the abrasive grains. Therefore, as described above, the upper or side of the holding shaft 13 does not hinder the aforementioned nozzles. A nozzle 17 for liquid spray is provided at a position where the liquid is sprayed, and the liquid or the liquid 30 containing the abrasive grains is sprayed toward the plate-shaped cutting member η and the plate-shaped polishing member 21 by the nozzle π. In this case, the liquid may be an aqueous solvent, a solvent containing abrasive grains, an aqueous solvent containing a surfactant, etc. The spray materials are also in accordance with the material of the plate-shaped cutting member 11 described above. Further, it is preferable that the nozzle 17 is sprayed at a time when the high pressure air is sprayed on the nozzle 15 to start the rotation of the plate-shaped cutting member 11 and the plate-shaped polishing member 21. [Experimental Example 1] [Experimental Example 1] The hair removal operator of the glass epoxy resin reinforcing plate which is next to the component φ assembly portion of the flexible printed circuit board was subjected to a length of 50 mm and a width. A reinforcing plate (plate-shaped cutting member 11) having a thickness of 1 mm and a thickness of 1 mm is passed through a circular hole 12 having a diameter of 3.0 mm from a position facing the end portion 12 of the longitudinal direction. Then, the reinforcing plate is overlapped by 2 pieces. And the holding shaft 13 having a diameter of 2.6 mm is inserted, and the high pressure gas of 〇·4 MPa is applied to the holding shaft in parallel by the nozzle 15 for 2 seconds/time from the position above the holding shaft. Spraying, and the reinforcing plate is surface-finished in 60 seconds. As a result, in the case of the glass epoxy resin reinforcing plate, even the friction sliding of the reinforcing plates of 14 1271267 I 5 can sufficiently perform the work of dehairing. [Experimental Example 2] [Explanation Example 2] For the deburring operation of the cut portion of the aluminum metal reinforcing plate to be attached to the component assembly portion of the flexible printed circuit board, the length is 50 and the width is 25 mm. A reinforcing plate (plate-shaped cutting member 11) having a thickness of 〇3 mm is opened with a circular hole 12 having a diameter & 〇 mm from a position facing the end portion 12 of the longitudinal direction. Further, a sus plate having a thickness of 〇·3 mm of the sandpaper of the number 1200 having the same shape as the reinforcing plate was attached to both surfaces as the plate-shaped polishing member 21, and the reinforcing plate and the plate-shaped polishing member were alternately The holding shaft 13 having a diameter of 2·6 mm is inserted into the one piece, and the high pressure gas of the 〇·4 MPa is held by the nozzle 15 at a position 80 mm above the holding shaft, and the shaft is applied in parallel for 2 seconds/time. Spraying to rotate the reinforcing plate and the plate-like abrasive member. Then, 5 g of sodium nitrate as a surfactant and 5 g of a dispersion solution of talc-containing talc powder having a particle size of granules were sprayed from the nozzle 17 at a flow rate of 12 ml per minute, and in a state thereof. The squat is continuously rotated for 2 seconds to perform face finishing. In addition, the weight of the aluminum metal reinforcing plate and the plate-shaped abrasive used in this time is about 1:2.5. [0038] In the case of any of the above experimental examples, the surface finishing operation of the deburring can be performed in a relatively short time. Moreover, depending on the choice of the liquid to be sprayed and the abrasive material, the application range can be further extended. In addition, the present invention can be variously modified without departing from the spirit and scope of the invention, and the invention can be taken as a matter of course. 15 127.1267 BRIEF DESCRIPTION OF THE DRAWINGS [0040] FIG. 1 is an explanatory view showing an overall configuration of the present invention.
