Description

[Technical field]

[0001] The present invention relates to a method for fixing a printed circuit board in a router processing device that performs cutting out the outer periphery of a printed circuit board or a slot or inner window within a printed circuit board (hereinafter referred to as "router processing"), and to a router processing device that performs the method for fixing a printed circuit board in the router processing device. [Background technology]

[0002] In recent years, printed circuit boards are being called upon to function not only as electronic components but also as structural or machine components, and there is also a demand for the printed circuit boards themselves to be smaller and more precise. Furthermore, even when multiple printed circuit boards are cut out from a single board to become the final product (hereinafter, the original single board is referred to as the "parent board" and the multiple printed circuit boards cut out from the parent board to become the final product are referred to as "child boards"), the child boards themselves are assembled as independent single components, so high processing precision is required even in the router processing of the child boards.

[0003] Therefore, in order to realize high-precision router processing for the daughter board, which is required to be compact and highly accurate in addition to serving as a mechanical or mechanical part, it has been proposed to stack the mother board and lower board on a template fixed to the processing table of the router processing device and fix them using board positioning pins, and to form internal pin holes in the daughter board using the same device, and then individually insert the internal pins into the internal pin holes of the mother board and lower board (see Patent Document 1).

[0004] Therefore, since the inner pin holes are formed in the mother board and the lower board by the same device, there is no need to set a significant diameter difference between the diameters of the inner pin holes and the inner pins, and the dimensional tolerance of both is approximately ±0 μm, so the inner pins can be inserted into the inner pin holes to fix the child board. Therefore, the child board will not oscillate during router processing in the router processing device, and the processing accuracy in the router processing of the child board can be reduced to ±50 μm or less.

[0005] However, when the lower plate and mother board are stacked and the board positioning pins are inserted into the board positioning pin holes in a template fixed to the processing table of the router processing device, even a slight misalignment of the stacked lower plate and mother board can cause partial lift between the lower plate and mother board, and although the processing accuracy can be kept within ±50 μm, it is difficult to improve the accuracy beyond that.

[0006] Furthermore, the attachment and detachment of the substrate positioning pins to the substrate positioning pin holes in the template can cause wear and deformation of the substrate positioning pin holes, which can result in rattling and reduced processing accuracy, so it is necessary to manage the number of times the substrate positioning pins are attached and detached from the substrate positioning pin holes. For this reason, currently, there is no choice but to manually fix the lower plate and the mother board onto the template in that order, with the board positioning pins remaining fixed to the template.

[0007] In addition, the router processing equipment also carries out the preparatory work of inserting the board positioning pins into the board positioning pin holes in the lower plate and mother board, and even into the board positioning pin holes in the template to form a single unit, the work of recovering the child boards, which are the products cut out by router processing from the mother board after router processing, and the work of removing the inner pins that have been dropped into the inner pin holes in the template, as well as any residual material from the lower plate and mother board. As a result, router processing within the router processing device becomes intermittent, significantly reducing the operating efficiency of the router processing work, and since the various tasks performed within the router processing device are performed manually by the operator, this also reduces the operator's work efficiency. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2015-199224 A Summary of the Invention [Problem to be solved by the invention]

[0009] The problem to be solved is that when a lower plate and a mother board are fixed by inserting board positioning pins into board positioning pin holes of a template fixed to a processing table, rattle occurs due to wear and deformation of the board positioning pin holes of the template as the board positioning pins are attached and detached, and there is a limit to how much the processing accuracy can be improved due to the oscillation during router processing, making it difficult to obtain processing accuracy beyond this level.

[0010] Furthermore, within the router processing equipment, the operator must manually perform the following preparatory work before router processing, which involves layering the lower plate and mother board by fitting their board positioning pin holes into the board positioning pins of the template; recovering the child boards, which are the products cut out from the mother board by router processing; and removing any residual material from the lower plate and mother board within the router processing equipment.As a result, the router processing work is intermittent, reducing the operating efficiency of the router processing equipment and also reducing the work efficiency of the operator. [Means for solving the problem]

[0011] The first feature is, A router processing device including at least a router processing mechanism for performing router processing and a processing table, First, a lower plate and a printed circuit board, or a lower plate, a printed circuit board, and an upper plate are stacked and fixed on a plate-shaped relay template to form a board template unit. The substrate template unit is fixed to a processing table. 、 Further, it is provided with an inner pin hole drilling and inner pin driving mechanism, and one printed circuit board constituting the board template unit can be divided into a plurality of printed circuit boards that become products (hereinafter, the original single printed circuit board is referred to as a "parent board", and the printed circuit boards that are divided from the parent board into a plurality of products are referred to as "child boards"); On the upper surface of the relay template constituting the above-mentioned substrate template unit, inner pin relief holes are pre-drilled at positions corresponding to the multiple inner pin holes to be drilled in the child board, as described below, and in the lower plate and mother board, or the lower plate and mother board, and upper plate, which are layered and fixedly held on the relay template constituting the above-mentioned substrate template unit, inner pin holes are drilled at predetermined positions of the child board constituting the lower plate and mother board, or the lower plate and mother board, and upper plate, by an inner pin hole drilling mechanism, and inner pins are driven from above into the drilled inner pin holes by an inner pin driving mechanism, thereby integrating the lower plate and mother board, or the lower plate and mother board, and upper plate.

[0012] Therefore, the printed circuit board is fixedly held on the relay template as a board template unit, with the lower plate and the printed circuit board, or the lower plate, the printed circuit board, and the upper plate, layered together, and the entire board template unit is carried into the processing table of the router processing device and fixed to the processing table before processing, and is carried out from the router processing device after processing. As a result, the assembly work of the substrate template unit, the recovery work of the product printed circuit board, and the removal of residue from the lower plate and printed circuit board, or the lower plate, printed circuit board, and upper plate that make up the substrate template unit, can all be performed outside the router processing apparatus, so that router processing work can be performed continuously in the router processing apparatus, improving the operating efficiency.

[0013] Furthermore, the operator can concentrate on performing the above-mentioned tasks outside the router processing device, and the operator has greater freedom in terms of the distance he or she must travel and the range of work required for the above-mentioned tasks without being restricted by the inside of the router processing device, thereby improving the operator's work efficiency.

[0014] Furthermore, within the router processing equipment, in the relay template that constitutes the substrate template unit, the lower plate and the mother plate, or the lower plate, the mother plate, and the upper plate together form a mother plate that is layered and fixed together. At predetermined positions of the child plate that constitutes the mother plate, inner pin holes are drilled by the same inner pin hole drilling mechanism, and the inner pins are driven by the inner pin driving mechanism. Therefore, there is no need to provide a significant diameter difference between the diameters of the inner pin holes and the inner pins, and the dimensional tolerance between the two is approximately ±0. As a result, the lower plate and the mother plate, or the lower plate and the mother plate, and the upper plate, which are layered and fixed to the relay template constituting the substrate template unit, are firmly fixed in accurate positions relative to each other. Furthermore, when the lower plate and the mother plate, or the lower plate and the mother plate, and the upper plate are integrated with the relay template by the substrate fixing pins and the template fixing pins are firmly held by the template clamper of the processing table, the substrate template unit is firmly fixed in an accurate position relative to the processing table, so that the mother plate does not swing during router processing, and more accurate router processing of the daughter plate can be performed.

[0015] In addition, after router processing is completed for the mother board incorporated in the substrate template unit, the internal pins that are driven into predetermined positions in the lower plate and mother board, or the lower plate, mother board, and child board that constitute the upper plate, which together with the relay template form the substrate template unit, are dropped into the internal pin relief holes of the relay template by the internal pin driving mechanism, and then the entire substrate template unit is transported outside the router processing apparatus and collected. On the other hand, since the substrate template unit consisting of the lower plate and mother plate, or the lower plate, mother plate, and upper plate, which are layered and fixed to the relay template, is created and prepared outside the router processing device, it is possible to prepare in advance the substrate template unit to be subjected to router processing next.By preparing in advance the substrate template unit to be subjected to router processing next after performing router processing on one substrate template unit, the router processing work can be performed continuously in the router processing device, thereby improving not only the operating efficiency of the router processing device but also the work efficiency of the operator.

[0016] Furthermore, the inner pin relief holes provided in the relay template are pre-drilled to correspond to the type of daughter board that constitutes the mother board, so there is no need to change the relay template to match the mother board to be processed.

[0017] Based on the first characteristic, the second characteristic is as follows: The relay template constituting the substrate template unit has a plurality of substrate fixing pins on an upper surface and a plurality of template fixing pins on a lower surface, the plurality of template fixing pins being provided vertically at predetermined positions on each surface; A plurality of holes for substrate fixing pins are pre-drilled in the lower plate and the printed circuit board, or the lower plate, the printed circuit board, and the upper plate, which constitute the substrate template unit, at positions corresponding to a plurality of substrate fixing pins provided on the upper surface of the relay template; A processing table of the router processing device is provided with a plurality of template clampers at positions corresponding to a plurality of template fixing pins provided on a lower surface of a relay template constituting a substrate template unit, a lower plate and a printed circuit board, or a lower plate and a printed circuit board, and an upper plate are fitted into holes for the board fixing pins, which are formed on the upper surface of the relay template, and the lower plate and the printed circuit board, or the lower plate and the printed circuit board, and the upper plate are stacked and fixed together with the relay template to form a board template unit, and The relay template constituting the substrate template unit has template fixing pins provided on the lower surface thereof, which are gripped by a template clamper provided inside the processing table and fixed to the processing table.

[0018] Therefore, in the relay template that constitutes the board template unit, the board fixing pins that firmly hold the lower plate and printed circuit board, or the lower plate and printed circuit board and upper plate, while being stacked together, remain erected on the upper surface of the relay template throughout multiple processing operations, and the board fixing pins are not attached or detached. Therefore, there is no possibility of wear or deformation of the holes for the board fixing pins that are provided in the relay template to allow the board fixing pins to be erected, and there is no need to manage the number of times the board fixing pins are attached and detached. The template fixing pins are accurately and firmly held by the template clamper installed inside the processing table, so that the relay template is firmly fixed in a precise position relative to the processing table, and further, the board fixing pins erected on the relay template are inserted into the board fixing pin holes in the lower plate and printed circuit board, or the lower plate and printed circuit board, and upper plate, which are firmly held while being stacked on top of each other, so that the printed circuit board of the board template unit is firmly and accurately fixed in a precise position within the router processing apparatus. As a result, the printed circuit board does not vibrate during router processing, and high-precision router processing can be performed.

[0019] In addition, the board fixing pins to be erected on the relay template should be appropriately erected in two locations in the center of the relay template in the front-to-rear direction, as described below, when the board template unit is carried into the processing table of the router processing device, or in three locations out of the four corners. In addition, as for the shape of the holes for the board fixing pins that are pre-drilled in the lower plate, or in the lower plate, upper plate, and printed circuit board to match the board fixing pins, if the board fixing pins are provided in two locations in the center of the front-to-rear direction of the relay template, round holes are appropriate, and if the board fixing pins are provided in three locations out of the four corners of the relay template, all three should be round holes, or only one should be a round hole so that the position can be adjusted, and the other two diagonally located holes should be elongated holes.

[0020] First feature or No. 2 Based on one of the above characteristics, the third characteristic is: The above-mentioned method for fixing a printed circuit board in a router processing apparatus is carried out to provide a router processing apparatus.

[0021] Therefore, in the router processing device, the printed circuit board or mother board is fixed to the processing table as a board template unit and then router processing is performed, and the creation of the board template unit and the collection of the processed printed circuit board or mother board after router processing can be performed by an operator outside the router processing device. As a result, the router processing device can perform router processing continuously, and the above-mentioned work by the operator can be performed in a concentrated manner outside the router processing device, thereby improving the operating efficiency of the router processing device and the work efficiency of the operator.

[0022] Furthermore, when the printed circuit board or mother board is accurately and firmly fixed together with the lower plate, or with the lower plate and the upper plate together by the inner pins driven in, and is firmly and accurately fixed in position on the processing table via the relay template of the board template unit, router processing can be performed with high precision on the printed circuit board.

[0023] Furthermore, in the router processing device, the printed circuit board or mother board is simply fixed to the processing table by the board template unit consisting of the lower plate or the lower plate, the upper plate, and the relay template, and no new equipment is added, and it is sufficient to simply change the design of the conventional loading and unloading mechanism in accordance with the thickness and weight of the board template unit. Also, for this reason, it is not necessary to expand the installation space of the router processing device or change the layout of the line, and even when the present invention is implemented in an existing router processing device, it is possible to prevent a decrease in operating efficiency, such as a long-term suspension of use of the router processing device. Effect of the Invention

[0024] The present invention provides a board template unit in which a printed circuit board or a mother board is layered and fixed to a relay template with a lower plate, or with a lower plate and an upper plate, so that the preparation and product recovery operations associated with router processing can be carried out in a concentrated manner outside the router processing apparatus, thereby providing the excellent effect of improving the operating efficiency of the router processing apparatus as well as the work efficiency of the operator.

[0025] Furthermore, the board fixing pins of the relay template, which firmly holds the lower plate and the printed circuit board or mother board, or the lower plate and the printed circuit board or mother board, and the upper plate while they are stacked together, remain fixed to the relay template, so there is no wear or deformation of the holes for the board fixing pins provided in the relay template due to the attachment and detachment of the board fixing pins, and there is also the excellent effect of eliminating the need to manage the number of times the board fixing pins are attached and detached, and improving processing accuracy.

[0026] Furthermore, even when implementing the present invention in an existing router processing apparatus, no new equipment is added, and there is no need to expand the installation space for the router processing apparatus or change the line layout. All that is required is to modify the design of the conventional loading / unloading mechanism in accordance with the thickness and weight of the substrate template unit. This has the excellent effect of eliminating the need to suspend use of the router processing apparatus and preventing a decrease in operating efficiency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] A board template unit is made by stacking and firmly holding a lower plate and a printed circuit board or a mother board, or a lower plate and a printed circuit board or a mother board, and an upper plate on the relay template, and the board template unit is carried into a processing table in a router processing device and fixed therein. After processing, the board template unit is carried out from the processing table to the outside of the router processing device, and the processed printed circuit board or child board is collected outside the router processing device and residues from the lower plate and the printed circuit board or the mother board, or the lower plate and the printed circuit board or the mother board, and the upper plate are removed. Meanwhile, a board template unit to be processed next, which has been prepared in advance outside the router processing device, is carried into the processing table in the router processing device and fixed therein, thereby allowing the router processing work to be performed continuously and the operator to work in a concentrated manner. EXAMPLES

[0029] FIG. 1 shows a unit-type router processing device A according to an embodiment of the present invention. In other words, the unit type router processing device A is a router processing device having six processing axes, which is the current mainstream, and is composed of a router processing device 1, a work table 5 corresponding to the six processing axes, a loading / unloading mechanism 6 that connects the router processing device 1 and the work table 5 so as to allow a substrate template unit 7 described later to be freely moved, and a control device (not shown) that controls the router processing device 1, the work table 5, and the loading / unloading mechanism 6 in an integrated manner. A workbench 5 is disposed on the rear side (the upper part in FIG. 1. Hereinafter, the rear side may be referred to as the "rear") of the unit-type router processing device A. In the following, only a portion of the unit-type router processing device A that corresponds to one processing axis will be explained (see FIG. 2).

[0030] The printed circuit board to be router processed in the unit-type router processing device A is the one to be router processed as the board template unit 7. The following explanation is based on the assumption that a single printed circuit board is processed and cut out to become multiple printed circuit boards as products. The original single printed circuit board is called the "mother board 12," and the multiple printed circuit boards cut out from the mother board 12 to become products are called the "child boards 12'."

[0031] Here, as shown in Fig. 4, the substrate template unit 7 is formed by stacking and firmly holding a mother substrate 12, a lower plate 13 and an upper plate 14 together in a relay template 8. Although Fig. 4 shows one mother substrate 12, multiple mother substrates may be stacked. That is, the relay template 8 constituting the substrate template unit 7 is a rectangular plate made of extremely hard glass epoxy resin having a thickness of 8 mm, and has three substrate fixing pins 9 at three of the four corners on its top surface, and two template fixing pins 10 at the center in the front-to-back direction on its bottom surface, standing vertically on each surface.

[0032] Furthermore, on the upper surface of the relay template 8, inner pin clearance holes 11 are provided at positions corresponding to the inner pin holes 13', 12'a, 14' drilled by an inner pin hole drilling mechanism (not shown; the router of the router processing device 1 itself can also serve as the inner pin hole drilling mechanism) provided in the unit type router processing device A for the lower plate 13, the child board 12' in the mother board 12, and the upper plate 14, which are firmly held while being stacked on top of each other. The inner pin clearance holes 11 have a diameter larger than the hole diameter of the inner pin holes 13', 12'a, 14'. As a result, the inner pins 15 that have been driven into the inner pin holes 14', 12'a, and 13' by an inner pin driving mechanism (not shown; the router of the router processing device 1 itself may also serve as the inner pin driving mechanism, or the inner pin driving mechanism may also serve as the inner pin hole drilling mechanism) to firmly hold the lower plate 13, the child board 12', and the upper plate 14 together can be easily retrieved by being further dropped into the inner pin relief hole 11 by the inner pin driving mechanism after router processing. Furthermore, the internal pin holes 12'a provided in the daughter boards 12' inside the mother board 12 are provided in three of the four corners of each daughter board 12', and the internal pin holes 13', 14' provided in the lower plate 13 and the upper plate 14, as well as the internal pin relief hole 11 provided in the relay template 8, are also provided to correspond to the internal pin holes 12'a provided in the daughter boards 12'.

[0033] In addition, the lower plate 13, the mother board 12 and the upper plate 14 which together with the relay template 8 constitute the board template unit 7 are each pre-drilled with board fixing pin holes 13'', 12'', 14'' at positions corresponding to the board fixing pin 9 erected on one surface of the relay template 8, so that the board fixing pin holes 13'', 12'', 14'' fit over the board fixing pin 9.

[0034] Therefore, when creating the substrate template unit 7, the substrate fixing pins 9 erected on one side of the relay template 8 are fitted into the substrate fixing pin holes 13", 12", 14" pre-drilled in the lower plate 13, the mother plate 12 and the upper plate 14, so that the lower plate 13, the mother plate 12 and the upper plate 14 are layered and firmly held together by the relay template 8.

[0035] Furthermore, in the unit-type router processing apparatus A, inner pin holes 13', 12'a, 14' are drilled in the lower plate 13, the mother board 12 and the upper plate 14 by an inner pin drilling mechanism provided in the router processing apparatus 1, and inner pins 15 are driven into the inner pin holes 13', 12'a, 14' by an inner pin driving mechanism provided in the same apparatus 1, thereby making the layered lower plate 13, the mother board 12 and the child board 12', and the upper plate 14 more firmly integrated with each other.

[0036] Next, the router processing device 1 of the unit-type router processing device A that performs router processing on the above-mentioned substrate template unit 7 includes a router processing mechanism (not shown, same below) that performs router processing, an inner pin drilling and driving mechanism (not shown, same below) that drills inner pin holes 13', 12'a, 14' in the lower plate 13, mother substrate 12 and upper plate 14 that constitute the above-mentioned substrate template unit 7 and drives inner pins 15 into the inner pin holes 13', 12'a, 14', and a processing table 2 that fixes the substrate template unit 7 during router processing. Although not shown, the router processing mechanism and the inner pin drilling and driving mechanism provided in the router processing device 1 can be those provided in a conventional router processing device.

[0037] Here, during the above-mentioned router processing, the substrate template unit 7 is fixed to the processing table 2 as shown in FIG. That is, when the substrate template unit 7 is carried into the processing table 2, in order to fix the substrate template unit 7 in a predetermined position, two sets of template clampers 3, 4, each consisting of two blocks 3', 3" and 4', 4", which hold the template fixing pins 10, are installed in positions corresponding to the two template fixing pins 10 standing on the underside of the relay template 8 that constitutes the substrate template unit 7, so that they never protrude from the surface of the processing table 2.

[0038] Of the front and rear template clampers 3, 4, the front template clamper 3 provided at the front side (lower side in FIG. 1; the same applies below) of the unit type router processing device A is made up of two blocks 3', 3" arranged in the front-rear direction. The front fixed block 3' has a locking portion 3'a that is V-shaped in cross section and is fixed to the processing table 2, and the front pressure block 3" slides toward the front fixed block 3' and presses and holds the template fixing pins 10. The rear template clamper 4 on the back side of the unit type router processing device A is made up of a rear fixed block 4' and a rear pressure block 4" that are arranged facing each other in a direction perpendicular to the front-rear direction of the unit type router processing device A. The rear fixed block 4' has a rectangular cross section and is fixed to the processing table 2, and the rear pressure block 4" has a rectangular cross section and slides toward the rear fixed block 4' and presses and holds the template fixing pins 10.

[0039] Therefore, after the two front and rear template fixing pins 10 of the relay template 8 that constitutes the substrate template unit 7 are positioned between the blocks 3', 3", 4', 4" that constitute the front and rear template clampers 3, 4, the front pressure block 3" slides toward the front fixed block 3', and the rear pressure block 4" slides toward the rear fixed block 4', whereby the two front and rear template fixing pins 10 are pressurized and gripped, respectively. In particular, the template fixing pin 10 positioned between the front fixed block 3' and the front pressure block 3" is firmly gripped by the front fixed block 3' and the front pressure block 3" while being guided toward the tip of the V-shaped engaging portion 3'a provided on the front fixed block 3' in the sliding direction, and the template fixing pin 10 positioned between the rear fixed block 4' and the rear pressure block 4" is firmly gripped while undergoing position correction toward the rear fixed block 4' due to the sliding of the rear pressure block 4". As a result, the substrate template unit 7 is fixed to the processing table 2 accurately and firmly.

[0040] Here, the front and rear template clampers 3 and 4 of the processing table 2 are disposed internally at positions corresponding to a plurality of template fixing pins 10 erected on the lower surface of an intermediate template 8 constituting a substrate template unit 7 . Therefore, since there are currently two basic sizes of the printed circuit boards or mother boards 12 to be processed, the sizes of the relay templates 8 which, together with the printed circuit boards or mother boards 12, constitute the board template unit 7 will also be unified into two types. For this reason, of the front and rear template clampers 3, 4 installed inside the processing table 2, the front template clamper 3 is common regardless of the size of the relay template 8, and the rear fixed block 4' and rear pressure block 4" of the rear template clamper 4 have their long sides each made to have a rectangular cross section, so that they can be used for any size of relay template 8.

[0041] Next, the work table 5 that constitutes the above-mentioned unit type router processing device A has two work tables, an upper one 5' and a lower one 5" on which various operations such as creating and dismantling the substrate template unit 7 are performed. Of these, the upper work table 5' and the lower work table 5" have a fixed gap between them so that the substrate template unit 7 can be loaded onto and unloaded from the processing table 2 of the router processing device 1. The upper work table 5' and the lower work table 5" can be freely raised and lowered so that they are approximately the same height as the processing table 2 in the router processing device 1. The upper work table 5' and the lower work table 5" can be used alternately. That is, for example, a substrate template unit 7 is created on the upper work table 5', the substrate template unit 7 is carried into the router processing device 1, and while the substrate template unit 7 is being processed by the router, the upper work table 5' is lifted and the lower work table 5" is raised. The next substrate template unit 7 is created on the lower work table 5", and then the lower work table 5" is lowered to its original position and the substrate template unit 7 after the router processing is carried out to the upper work table 5' outside the router processing device 1. Thereafter, the work table 5 is raised and the next substrate template unit 7 is carried from the lower work table 5" into the router processing device 1. Then, while the router processing is being carried out, the child substrate 12', which is the product, is collected from the substrate template unit 7 that has been carried out on the upper work table 5', and residual materials of the lower plate 13, the mother substrate 12, and the upper plate 14 can be removed. By repeating this process, the unit type router processing device A can be operated continuously.

[0042] The loading / unloading mechanism 6 connecting both the upper work table 5' and the lower work table 5" of the work table 5 with the processing table 2 may be as follows. For example, it may be composed of an upper work table belt conveyor built into the upper work table 5', a lower work table belt conveyor built into the lower work table 5", an intermediate belt conveyor provided on the rear side of the router processing device 1, and a lift mechanism built into the router processing device 1 and having an extendable cylinder that raises and lowers the substrate template unit 7 and moves it to a predetermined position (the specific configuration is not shown). Therefore, before router processing, regardless of whether the board template unit 7 has been created on the upper work table 5' or the lower work table 5", it can be moved and placed on the relay belt conveyor which operates in sync with the upper or lower work table belt conveyor by operating either the upper work table belt conveyor built in the upper work table 5' or the lower work table belt conveyor built in the lower work table 5". The board template unit 7 placed on the relay belt conveyor moves to the vicinity of the rear end (the edge on the back side) of the processing table 2. Then, by a lift mechanism built in the router processing device 1, the board template unit 7 on the relay belt conveyor is lifted higher than the protruding length of the template fixing pins 10 erected on the lower surface of the relay template 8, and moves until the template fixing pins 10 reach approximately the position above the template clampers 3, 4 built in the processing table 2 of the router processing device 1. Then, the substrate template unit 7 is lowered onto the processing table 2 so that the template fixing pins 10 are positioned between the blocks 3 ′, 3 ″ and 4 ′, 4 ″ that constitute the template clampers 3 , 4 . Furthermore, after router processing, the substrate template unit 7 on the processing table 2 is lifted by a lift mechanism installed inside the router processing apparatus 1 to a height higher than the protruding length of the template fixing pins 10 erected on the underside of the relay template 8, and moved to and placed on the relay belt conveyor near the rear end of the processing table 2. The substrate template unit 7 placed on the relay belt conveyor then moves to the opposite end of the relay belt conveyor, i.e., near the front end of either the upper work table 5' or the lower work table 5". The substrate template unit 7 is then carried out and placed on either the upper work table belt conveyor or the lower work table belt conveyor, which are operating in sync.

[0043] As described above, in the unit-type router processing device A of the present invention, the substrate template unit 7 performs router processing depending on the operator's work content, the status of the router processing device 1, the carry-in / carry-out mechanism 6, and the work table 5 at each stage shown in FIG. The first stage is the assembly process of the substrate template unit 7. The operator places the relay template 8 on the upper work table 5' of the work table 5 installed on the back side of the unit-type router processing device A, which is an embodiment of the present invention, and then assembles the board template unit 7 by fitting the lower plate 13, the mother board 12, and the upper plate 14, in that order, into the board fixing pin holes 13'', 12'', and 14'', which have been pre-drilled in each of them, onto the board fixing pins 9 erected on the upper surface of the relay template 8, thereby firmly holding them together. The second stage is a process of loading the substrate template unit 7 and preparing for router processing. The operator adjusts the height position of the upper work table 5' to be substantially the same as the height of the processing table 2, and then instructs the carry-in / out mechanism 6 to carry the assembled substrate template unit 7 onto the processing table 2 in the router processing apparatus 1. In response to this, the carry-in / out mechanism 6 carries the substrate template unit 7 on the upper work table 5' onto the processing table 2 in the router processing apparatus 1. In the unit-type router processing device A, a control circuit that collectively controls the unit-type router processing device A, the loading / unloading mechanism 6, and the workbench 5 confirms that the substrate template unit 7 has been loaded and placed on the processing table 2, and then the template fixing pin 10 erected on the underside of the relay template 8 that constitutes the substrate template unit 7 is grasped by template clampers 3, 4 installed inside the processing table 2 and fixed to the processing table 2. The third stage is a process of processing the substrate template unit 7 and a process of assembling the substrate template unit 7. After the operator confirms that the board template unit 7 has been carried into the router processing apparatus 1 and fixed to the processing table 2, the operator instructs router processing. In response to this, in the router processing apparatus 1, the inner pin holes 13', 14', 12'a are drilled in the board template unit 7 fixed on the processing table 2 in correspondence with predetermined positions of the lower plate 13, the child board 12' constituting the mother board 12, and the upper plate 14, and the inner pins 15 are driven in by the inner pin drilling and driving mechanism provided in the router processing apparatus 1. Then, the predetermined router processing and the like are performed on the mother board 12. The operator also moves to the rear side of the unit-type router processing device A, raises the lower work table 5'', then flips up the upper work table 5' to open the lower work table 5'' upward, and places the relay template 8 on the lower work table 5''. Then, the operator fits the board fixing pins 9 erected on the upper surface of the lower plate 13, mother board 12, and upper plate 14, in that order, into the board fixing pin holes 13'', 12'', and 14'' that have been pre-drilled in each of them, and assembles the board template unit 7 by firmly holding them together. The fourth stage is a process of unloading the substrate template unit 7. The operator again moves to the front side of the unit-type router processing device A and, after confirming that the router processing of the mother board 12 has been completed normally, instructs the control device of the router processing device 1 to use the inner pin drilling and driving mechanism to punch out the inner pins 15 into the inner pin relief holes 11 formed in the relay template 8 for the processed board template unit 7. Then, after confirming that the inner pins 15 have been punched out, the operator releases the template clampers 3 and 4 provided in the processing table 2 which are holding the template fixing pins 10 erected on the underside of the relay template 8 constituting the board template unit 7, thereby releasing the fixation to the processing table 2. Then, the operator moves to the rear side of the unit-type router processing device A and instructs the carry-in / carry-out mechanism 6 to carry-out the substrate template unit 7, and at the work table 5, the upper work table 5' is released from its raised position and lowered so that the height position of the upper work table 5' is approximately the same as that of the processing table. Then, the carry-in / carry-out mechanism 6 carries-out the processed substrate template unit 7 on the processing table 2 and places it on the upper work table 5', and the operator confirms that the substrate template unit 7 has been carried out. The fifth stage is the process of loading the substrate template unit 7 and preparing for router processing. It is basically the same as the second stage, with the only difference being that the substrate template unit 7 assembled on the lower work table 5" is loaded onto the processing table 2 in the router processing device 1 by the loading / unloading mechanism 6. Therefore, in order to enable the loading of the substrate template unit 7, the height position of the lower work table 5" is raised so that it is approximately the same as the height of the processing table 2. The sixth stage includes a processing step of the substrate template unit 7, a product recovery step, and an assembly step of the next substrate template unit 7. The substrate processing step is the same as the first half of the third stage. Meanwhile, the operator retrieves the product, the child substrate 12', from the processed substrate template unit 7 placed on the upper work table 5' in the fourth stage, and removes residues of the lower plate 13, the upper plate 14, and the mother substrate 12. The next assembly process of the substrate template unit 7 is performed on the upper work table 5', and is the same as in the first stage. The seventh stage is a process of unloading the substrate template unit 7. The operator moves to the front side of the unit-type router processing device A and performs the same tasks as those described in the first half of the fourth stage and gives instructions to the control device of the router processing device 1. After that, the operator moves to the rear side of the unit-type router processing device A and adjusts the height position of the lower work table 5" to the height position to which it was raised in the fifth stage. Then, as described in the second half of the fourth stage, the operator gives an instruction to remove the substrate template unit 7, and has the processed substrate template unit 7 on the processing table 2 removed by the carry-in / out mechanism 6 and placed on the lower work table 5", and checks it. The eighth stage is a process of loading the next substrate template unit 7 and preparing for router processing. The operator lowers the height position of the upper work table 5' set in the seventh stage so that the height position of the upper work table 5' is approximately the same as the height position of the processing table 2, and then issues the loading instructions described in the second stage to perform the loading work. Furthermore, the substrate template unit 7 carried into the router processing apparatus 1 is subjected to the fixing operation described in the latter half of the second stage by the control circuit of the router processing apparatus 1. The ninth stage is a processing step for the substrate template unit 7 and a product recovery step. The processing steps are the same as those described in the third stage. The product recovery step is also the same as the product recovery step in the sixth stage, except that in order to facilitate the work in this step, the upper work platform 5' is lifted and the position of the lower work platform 5" is raised, thereby raising the height position of the lower work platform 5". Thereafter, by repeating these steps, router processing can be continuously performed on the child boards 12' that constitute the parent board 12 by the unit type router processing device A. [Industrial Applicability]

[0044] At least the printed circuit board to be processed is layered on a relay template and held together to form a board template unit, and this board template unit is then transported into and out of the unit-type router processing device and processed therein.By doing this, various tasks other than router processing can be performed outside the router processing device, and router processing can be carried out continuously, so that this method can be applied not only to router processing devices but also to a variety of other processing devices.
