Description

  The present invention relates to a collective substrate dividing jig for dividing individual circuit boards for electric devices from, for example, a collective substrate in which a plurality of electric device circuit boards having the same shape are combined.

  In general, for example, a relatively small circuit board for an electric device such as a speaker microphone of a wireless device is manufactured in a plurality of pieces having the same shape from a single standard-sized material. FIG. 12 shows a collective substrate (hereinafter, simply referred to as “collective substrate”) produced by combining a plurality of circuit boards for electric equipment 110 manufactured by etching a standard-size material and performing a press process or the like. 100 is shown. In the following description, it is assumed that the reference numerals of the circuit boards for electric devices are properly used as 110, 110A, 110B,.

  The configuration example shown in FIG. 12 shows an example in which circuit boards for electric appliances 110A, 110B,... Are arranged in five columns in the first direction (X direction) and in two rows in the second direction (Y direction). Each of the circuit boards 110A, 110B,... For each electrical device is formed in a substantially final shape, and the circuit for each electrical device is considered in consideration of the transportation from the circuit board manufacturing process and the mounting process of the electronic components. The substrates 110A, 110B,... Are coupled to the guide portions 101, 102, and 103 of the collective substrate 100 by a plurality of narrow connection portions 121, 122, and 123 so that the substrates 110A, 110B,. In addition, each circuit board 110A, 110B ... for electric equipment is couple | bonded with the guide parts 101, 102, and 103 via the connection parts 121, 122, and 123 only in the 2nd direction, and in the 1st direction. It is not coupled to the other circuit boards 110A, 110B.

  In order to divide such a collective substrate 100 into individual circuit boards 110 for electric devices, a router bit that rotates at high speed is moved relative to the collective substrate 100 using an XY table or the like, and connected. There is known a router type substrate dividing apparatus for scraping off a part. By the way, the router type substrate dividing apparatus is expensive and requires a large installation space. Therefore, when the circuit board 110 for electric equipment is mass-produced, the router type board dividing apparatus is effective, but when the number of production is not so large, it is not suitable for cost effectiveness. In the case where the number of electric circuit boards 110 produced is not so large, conventionally, the operator holds the collective board 100 directly by hand, and separates the individual electric equipment circuit boards 110 from the collective board 100 manually. It was.

  As is clear from FIG. 12, the guide portions 101 and 103 at both ends of the collective substrate 100 in the second direction are respectively connected to the plurality of circuit boards 110A, 110B,. It is combined with Focusing on the electric equipment circuit board 110A on the upper right in the figure, consider the case where the electric equipment circuit board 110A is divided from the collective board 100 by hand. In general, the electric device circuit board 110A is held with one hand, and the stress is concentrated on the connection portions 122 and 123 with the other hand sandwiching the vicinity of the guide portion 101 indicated by reference numeral P1, and the connection portion 122 and 123 is broken. However, since the force applied to the guide part 101 is distributed to the connection parts of the circuit board 110 for other electrical devices, a force larger than the force necessary to actually break the connection parts 122 and 123 is applied. Must be added to. When the material of the collective substrate 100 is hard or thick, a large force must be applied, which increases the burden on the operator. Further, since the circuit board 110 for other electrical equipment is not held by hand, there is a possibility that the circuit board 110 for electrical equipment will be warped by an applied force, and a crack may be generated in a weak portion, There is a possibility that an electronic component mounted on the circuit board 110 for electric equipment is detached or damaged.

  As a prior art related to the present invention, a substrate break device for an electronic component described in Patent Document 1 is known. This apparatus manufactures substrates for electronic components such as thermal heads and chip resistors of many thermal transfer printers from a single ceramic substrate. Put a large number of slits parallel to the first direction and the second direction on one surface of the ceramic substrate, guide one side of one slit, sandwich the other side from both sides with a flat sandwiching member, By rotating the pinching member, stress is concentrated on the slit, and the ceramic substrate is broken along the slit. By performing this operation on all the slits in the first direction and the second direction, a large number of substrates for rectangular electronic components are manufactured.

FIG. 2 shows a state in which the second pinching member 30 is rotated in a predetermined direction with respect to the first pinching member 20, and the guide portion 101 of the collective substrate 100 is pinched between the first pinching member 20. FIG. 3 shows a state where the first sandwiching member 20 and the second sandwiching member 30 are integrally rotated with respect to the table 10 in a predetermined direction, and the guide portion 101 is separated from the collective substrate 100. Further, FIG. 4 shows that the collective substrate 100 is placed on the table 10 by changing the direction of the collective substrate 100 in order to separate the other guide portions 103 of the collective substrate 100, and between the first and second pinch members 20 and 30. Shows a state in which the guide portion 103 of the collective substrate 100 is sandwiched.

  The mounting surface 11 of the table 10 is longer than the length of the collective substrate 100 in the first direction (X direction) and collects in the second direction so that the portion excluding the guide portion 101 or 103 of the collective substrate 100 can be held. The guide portion 101 or 103 is shorter than the length of the substrate 100. The first pinching member 20 is rotatably coupled to the table 10 via the hinge 50 so that the axis (first axis) 51 of the hinge 50 that is the rotation axis thereof is parallel to the first direction. The length of the first pinching member 20 in the first direction is substantially the same as the length of the table 10 in the same direction, and the dimension in the second direction is shorter than that. The second pinching member 30 is rotatably coupled to the first pinching member 20 via the stay 60 so that the axis (second axis) 61 of the stay 60 that is the rotation axis thereof is parallel to the first direction. . The length of the second pinching member 30 in the first direction is substantially the same as the length of the aggregate substrate 100 in the same direction, and the length in the second direction is shorter than the length of the first pinching member 20 in the same direction. The materials of the table 10, the first pinching member 20, the second pinching member 30, and the handle 40 are not particularly limited. However, considering the ease of carrying and processing, an aluminum thick plate, a bakelite thick plate, or the like is used. it can.

  In this specific example, the electric circuit board 110 has portions (protrusions) 111 and 112 that protrude outward from the connection parts 121, 122, and 123 in the second direction. A stepped portion 31 having a height substantially the same as the thickness of the guide portion 101 or 103 of the collective substrate 100 is formed on the side of the second sandwiching member 30 facing the first sandwiching member 20, thereby The guide portion 101 or 103 of the collective substrate 100 can be sandwiched between the first sandwiching member 20 and the second sandwiching member 30. As shown in FIG. 2 or FIG. 4, the end 32 on the opposite side of the second pin 61 in the second direction of the second pinching member 30 holds the guide portion 101 or 103 of the collective substrate 100 in between. 10 and the first sandwiching member 20 are connected to each other, that is, directly above the first shaft 51, and connecting portions 122 and 123 that connect the guide portion 101 or 103 of the collective substrate 100 and the circuit board 110 for electric equipment. Or it is located in the vicinity of 121. Furthermore, a notch 33 for avoiding the protruding portion 111 or 112 of the electric device circuit board 110 is formed at the end portion 32 of the second sandwiching member 30. In other words, the portion between the two notches 33 in the end portion 32 of the second sandwiching member 30 is a portion in the vicinity of the connecting portions 122 and 123 or 121 of the collective substrate 100 excluding the circuit board 110 for electric equipment. It functions as a plurality of claw portions 34 for sandwiching. Although not clear from FIGS. 1 to 4, the first notch member 20 is also formed with a similar notch 22 at a portion facing the notch 33 (see FIG. 8).

  The handle 40 has an action part 41 parallel to the first direction and an operation part 42 perpendicular to the action part 41, and the force applied to the operation part 42 passes through the action part 41 to It is transmitted to two places separated in the first direction among the two sandwiching members 30. Thereby, a substantially uniform force can be transmitted to each claw portion 34 of the end portion 32 of the second pinching member 30.

  Engaging protrusions 12 and 13 for positioning the collective substrate 100 are provided on the mounting surface 11 of the table 10. The larger engagement protrusion 12 is engaged with, for example, an engagement hole 113 formed in the central portion of the circuit board 110 for electric equipment, and the electric equipment arranged in the first direction in the first row in the second direction. The circuit board 110 for electric equipment is engaged with the circuit boards 110A and 110X for electrical equipment at both ends. On the other hand, the smaller engagement protrusion 13 is engaged with an engagement groove or engagement hole 114 formed on the outer peripheral portion of the circuit board 110B for electric equipment at the end of the second row in the second direction. The positions and number of the engagement protrusions 12 and 13 are not particularly limited, and the guide portions 101 and 103 are connected to the first sandwiching portion from one end portion of the table 10 in a state where the collective substrate 100 is placed on the table 10. It is only necessary to hold the collective substrate 100 so that it protrudes to the 20 side and the connecting portions 122 and 123 are positioned in the vicinity of the first shaft 51. As shown in FIG. 4, in this embodiment, the collective substrate 100 can be similarly held on the table 10 regardless of the orientation of the collective substrate 100. Here, “regardless of the orientation of the collective substrate 100” means that in this specific example, the front and back sides are the same and the front and back in the second direction are reversed. However, the present invention is not limited to this. May be reversed, and the front and back may be reversed.

  Next, an operation or usage method of the collective substrate dividing jig 1 according to the first embodiment will be described. First, as shown in FIG. 1, the collective substrate 100 is placed on the table 10 with the end portion 32 of the second pinching member 30 facing up, and the circuit boards 110A and 110X for electrical equipment are placed. The engaging projection 113 is engaged with the engaging projection 113, and the engaging projection 13 is engaged with the engaging groove or the engaging hole 114 of the circuit board 110 </ b> B for electrical equipment. Then, the collective substrate 100 is positioned. Next, the handle 40 is operated to rotate the second pinching member 30 in a predetermined direction about the second shaft 61 as a rotation axis, as shown in FIG. Then, the bottom surface 35 of the second sandwiching member 30 is stationary with the bottom surface 35 in contact with the top surface 21 of the first sandwiching member 20, and between the step portion 31 of the second sandwiching member 30 and the top surface 21 of the first sandwiching member 20, The guide portion 101 of the collective substrate 100 is sandwiched. At this time, the protruding portion 111 of each electric circuit board 110 for electric equipment is located in the notch 33 portion of the second sandwiching member 30 and is not sandwiched by the first sandwiching member 20 and the second sandwiching member 30. On the other hand, portions in the vicinity of the connecting portions 122 and 123 that connect the individual electric device circuit boards 110 and the guide portions 101 are sandwiched by the claw portions 34 of the first sandwiching member 20 and the second sandwiching member 30, respectively.

  When the handle 40 is further operated, as shown in FIG. 3, the first pinching member 20 and the second pinching member 30 are integrally rotated in a predetermined direction with the first shaft 51 as a rotation axis. At this time, the force applied to the handle 40 is distributed almost uniformly on the plurality of claw portions 34 of the second pinching member 30 and further acts on the individual connection portions 122 and 123. In general, the material of the circuit board is brittle compared to other resin materials, although it exhibits some elasticity. Therefore, when a stress exceeding the elastic limit is applied to the connection parts 122 and 123, a brittle fracture occurs and the connection parts 122 and 123 are broken. In this case, the plurality of connection portions 122 and 123 that join the guide portion 101 and the plurality of circuit boards for electric appliances 110A.

  When the connecting portions 122 and 123 are broken, the handle 40 is operated in the opposite direction to bring the second pinching member 30 upright as shown in FIG. Then, the guide portion 101 separated from the collective substrate 100 and the remaining collective substrate 100 are removed from the table 10, and the orientation of the collective substrate 100 is changed as shown in FIG. To operate. In FIG. 4, the guide portion 103 on the opposite side of the collective substrate 100 is sandwiched between the first sandwiching portion 20 and the second sandwiching portion 30. In addition, the protruding portion 112 on the opposite side of the electric device circuit boards 110B... 110Z is located in the notch 33 portion of the second sandwiching member 30, and the electric device circuit boards 110B. The connecting portions 121 to be coupled are sandwiched by the claw portions 34 of the first sandwiching member 20 and the second sandwiching member 30, respectively. By further operating the handle 40 from this state, the opposite guide portion 103 is separated from the collective substrate 100.

  In the collective substrate dividing jig 1 according to the first embodiment, the central guide portion 102 of the collective substrate 1 cannot be separated. However, each circuit board 110 for electric appliances is only coupled to the central guide part 102 by one connection part 121 or two connection parts 122 and 123. Therefore, the circuit boards 110 for individual electric devices can be separated from the central guide portion 102 with a relatively small force even by manual work. Note that the collective substrate 100 does not have to be arranged in the first direction and the second direction as shown in each of the above drawings. For example, as shown in FIG. 13, the circuit board 110 for electric equipment is only in one direction. It may be arranged.

(Second Embodiment)
Next, a collective board dividing jig according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows the collective substrate dividing jig 2 according to the second embodiment and the collective substrate 100 placed on the table 10. The collective substrate 100 is the same as that shown in FIG. FIG. 6 shows a state in which the guide member 101 of the collective substrate 100 is sandwiched between the second sandwiching member 30 and the first sandwiching member 20 by rotating the second sandwiching member 30 in a predetermined direction. FIG. 7 shows a state where the first sandwiching member 20 and the second sandwiching member 30 are integrally rotated in a predetermined direction and the guide portion 101 is separated from the collective substrate 100. FIG. 8 shows a state in which the collective substrate dividing jig 2 is viewed from below. From FIG. 8, it can be seen that the notch 22 is also formed in the first sandwiching member 20 at a portion facing the notch 33 of the second sandwiching member 30. Members having the same functions as those of the collective substrate dividing jig 1 according to the first embodiment are denoted by the same reference numerals.

  The difference between the collective substrate dividing jig 1 according to the first embodiment and the collective substrate dividing jig 2 according to the second embodiment is that the second pinching member 30 is directly connected by the hinge 70 to the first pinching member 20. And the handle 40 is directly coupled to the second pinching member 30. Therefore, the structure is simple and the cost can be reduced. On the other hand, the distance between the handle 40 and the claw portion 34 of the second pinching member 30 is shortened, that is, the arm of the “lever” is shortened. As a result, the stress concentrated on the claw portion 34 is reduced. The collective substrate dividing jig 2 according to the second embodiment is suitable when the thickness of the collective substrate 1 is thin or the hardness of the material is low. Note that the shaft 71 of the hinge 70 corresponds to the second shaft.

(Third embodiment)
Next, a collective board dividing jig according to a third embodiment of the present invention will be described with reference to FIGS. FIG. 9 shows the collective substrate dividing jig 3 according to the third embodiment and the collective substrate 100 placed on the table 10 thereof. The collective substrate 100 is the same as that shown in FIG. In the first and second embodiments, only the guide portions 101 and 103 at both ends in the second direction of the collective substrate 100 can be separated, and the central guide portion 102 is manually separated. The collective substrate dividing jig 3 according to the embodiment can also separate the central guide portion 102. FIG. 9 shows a state where the guide portion 101 at one end of the collective substrate 100 has already been cut off and the central guide portion 102 is about to be cut off. FIG. 10 shows a state in which the second guide member 30 is rotated in a predetermined direction, and the central guide portion 102 of the collective substrate 100 is sandwiched between the second sandwich member 30 and the first sandwich member 20. FIG. 11 shows a state where the first pinching member 20 and the second pinching member 30 are integrally rotated in a predetermined direction and the central guide portion 102 is about to be separated from the collective substrate 100. Members having the same functions as those of the collective substrate dividing jig 1 according to the first embodiment are denoted by the same reference numerals.

  As can be seen from FIG. 9, in the collective substrate dividing jig 3 according to the third embodiment, the length of the first sandwiching member 20 in the second direction (Y direction) is the center guide of the collective substrate 100 in the same direction. It is set to be longer than the sum of the length of the portion 102 and the length of the circuit board 110 for electric equipment. Further, the length of the second pinching member 30 in the second direction is also set to be approximately the same as the length of the central guide portion 102 of the collective substrate 100 in the same direction and the length of the circuit board 110 for electric equipment. Yes. The side of the second pinching member 30 facing the first pinching member 20 is formed with the plurality of notches 33 and claw portions 34 at the end opposite to the second shaft 61, and the claw in the second direction. The length of the portion 34 is substantially the same as the length of the guide portion 102 at the center of the collective substrate 100 in the same direction. Further, a recess (stepped portion) 36 for preventing interference with the circuit board 110 for electric equipment is formed on the second shaft 61 side of the claw portion 34 on the side facing the first sandwiching member 20 of the second sandwiching member 30. Has been. Furthermore, on the upper surface 21 of the first sandwiching portion 20, engagement protrusions 23 that are engaged with the engagement holes 113 of the circuit board 110 for electric equipment are arranged in the first direction (X direction). In the third embodiment, since the central guide portion 102 of the collective substrate 100 is also separated by the collective substrate dividing jig 3, each of the divided circuit boards 110 for electric devices is the table 10 or the first sandwiching member. The same number of engagement protrusions 12 and 23 as the number of electric circuit boards 110 in the first direction are provided so as not to drop from the circuit board 20. Although not illustrated in FIGS. 9 to 11, the same notch 22 is formed in the first sandwiching member 20 in the third embodiment at a portion facing the notch 33 (see FIG. 8). ).

  As shown in FIGS. 10 and 11, the operation for separating the central guide portion 102 from the collective substrate 100 is the same as in the case of the first embodiment. At the stage where the separation operation shown in FIG. 11 is completed, two sheets of the state in which five circuit boards 110 for electric equipment are coupled to the guide portion 102 or 103 remain. Similar to the case shown in FIG. 4, this is placed on the table 10 while changing the orientation, and the same procedure is repeated, so that all the circuit boards 110 for electric appliances are collected by the collective board 100 without manual operation. That is, the collective substrate 100 can be divided into individual circuit boards 110 for electric devices. 9 to 11, regarding the portion sandwiched between the first sandwiching member 20 and the third sandwiching member 30, the individual electric device circuit boards 110 are coupled to the guide portion 102. Thus, at least two engaging protrusions 23 of the second pinching member 20 are sufficient as in the case of the first embodiment.

(Other variations)
The present invention is not limited to the above embodiment, and various modifications can be made. For example, depending on the shape of the circuit board 110 for electric equipment, as shown in each of the above embodiments, there are cases where the collective substrate 100 cannot be placed on the table 10 by changing the orientation. In that case, the first pinching member 20, the second pinching member 30 and the handle 40 having shapes corresponding to the guide portions 101 and 103 are provided at both ends of the table 10 in the second direction, respectively, from both sides. You may comprise so that the guide parts 101 and 103 may be fractured | ruptured.
