Conventionally, a technique described in Patent Document 1 has been proposed as a technique for simultaneously inserting a plurality of terminals of an electronic component into corresponding substrate holes. According to this Patent Document 1, it has a gripping claw that can be opened and closed, and by closing the gripping claw, a plurality of terminals arranged in a row can be gripped and inserted into the substrate hole in that state. . Thereby, the attachment of the plurality of terminals of the electronic component to the substrate can be performed efficiently and accurately.
JP 2003-179394 A

  However, in the assembling apparatus described in Patent Document 1, the terminals arranged in a row as described above can be accurately inserted into the substrate hole simultaneously, but a plurality of such rows of terminals are arranged in parallel. It cannot be applied to. Even if each terminal is set at a position corresponding to the board hole to some extent, by arranging the terminals in a plurality of rows in parallel, each terminal is caused by a dimensional error of each electronic component itself. In some cases, it cannot be accurately inserted into the hole of the substrate.

  For example, in FIG. 9, the electronic components 110 having a plurality of terminals 110a are arranged vertically, and the plurality of electronic components 110 are also arranged in the parallel direction via the plate 120 for radiating heat generated from the electronic components 110. The process of attaching the board | substrate 2 to the electronic component main body 100 which has been shown is shown. Further, the terminal 110a of each electronic component 110 substantially coincides with the position of the corresponding substrate hole 2a. However, when the plurality of electronic components 110 are stacked in this way, the dimensional errors of the plate 120 described above are accumulated, and a displacement occurs between the terminal 110a and the corresponding substrate hole 2a. Therefore, even if it is going to assemble the board | substrate 2 in the electronic component main body 100 as it is, since the terminal 110a cannot be inserted in the board | substrate hole 2a, it is necessary to correct the position of the terminal 2a.

  The present invention has been made in view of the above problems, and corresponds to each terminal of an electronic component in which a plurality of terminals are arranged in a row, and a row of such terminals is also arranged in a parallel direction. The position of each terminal is accurately and efficiently corrected so that it can be inserted into the corresponding board hole. An object of the present invention is to provide a position correction apparatus and a position correction method.

In order to achieve the above object, a terminal position correcting device in assembling a board according to claim 1 is a board in which terminals of electronic components in which a plurality of rows of terminals are arranged in parallel are formed on a common substrate. A device for correcting the position of each terminal so as to coincide with the position of the substrate hole when the electronic component is inserted into the hole and assembled to the substrate, and extends from the base and extends from the base . Two comb-shaped plates having a plurality of protrusions inserted between a plurality of rows, wherein the substrate hole when the substrate is assembled when the protrusion is inserted between the plurality of rows of the terminals. In order to sandwich the respective terminals with the protrusions at the positions of the respective rows, the device includes two comb templates that are slidable in the arrangement direction of the plurality of rows of the terminals, and among the two comb templates, One comb template bump Thickness of, than the thickness of the base portion of the comb plates are thicker toward the other of the comb plate, whereby said two comb plate projections, when sandwiched the terminal In order to prevent the terminal from being bent, each of the protrusions of the two comb templates has a region facing each other in the direction of sandwiching the terminal.

As described above, the electronic component main body in which the electronic components are stacked in the parallel direction has different terminals due to dimensional errors of the electronic components themselves or other components sandwiched between the electronic components. Is likely to deviate from the normal position (position where the substrate hole can be inserted) in the parallel direction. Therefore, by using the terminal position correcting apparatus in the board assembly according to the first aspect, the positions of all the terminals can be simultaneously corrected to the normal positions in the parallel direction. In this state, by inserting each terminal into the board hole, the electronic component main body can be efficiently and accurately assembled to the board.
Further, the protrusions of the two comb stencils have a region where the protrusions of the two comb stencils face each other in the direction in which the terminal is sandwiched. The terminal can be prevented from bending.

In the position correction device terminals in assembling board according to claim 2, at least one of the projections of the two comb plate, on the substrate hole when tried Kumitsukeyo the substrate in this state by sandwiching the terminal A groove for correcting the position in the direction of the row of the plurality of terminals is formed at a corresponding position.

  By forming a groove in the protrusion that forms the comb in this way, the terminal is corrected to a position where the groove is present when the terminal is sandwiched between the protrusions. That is, all the terminals can be corrected to the normal positions in the column direction including a plurality of terminals at the same time. Examples of the shape of the groove include a V shape, a trapezoidal shape, a U shape, and a semicircular shape. As a result, the electronic component main body can be more accurately assembled to the substrate.

In the position correction device terminals in assembling board according to claim 3, wherein the two comb plate projections, that coating for scratch prevention to the terminal when sandwiching the terminals is applied Features. Thereby, it is possible to prevent the terminals from being damaged when sandwiched by the protrusions.

The terminal position correction method in the board assembly of claims 4 to 6 corresponds to the terminal position correction apparatus in the board assembly of claims 1 to 3 described above, and can obtain the same actions and effects, respectively. Therefore, explanation is omitted.

In the position correction of pin in assembly substrate according to claim 7, wherein the first step, first the so terminal comes substantially on the center line between the two comb plate adjacent the projections, the two It is characterized by driving a comb template.

Thus, when setting two comb plates between the respective terminals, first the respective terminals to form a column to come substantially on the center line between adjacent protrusions. Here, the term “substantially on the center line” means that when a plurality of electronic components are stacked as described above, there is a greater possibility that the position of each terminal will be displaced. This is because there is a slight deviation from the center line with respect to the other terminal rows even if they are on the center line. However, to come to substantially on the center line between the thus projecting the terminal be formed adjacent each of the columns, by setting the two comb plates, between each adjacent protrusions reliably all the terminal Can be set.

  Embodiments of a terminal position correcting device (hereinafter simply referred to as a position correcting device) in board assembly according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram illustrating an electronic component main body 10 to be assembled with a substrate and a substrate 1 to be assembled to the electronic component main body 10 using the position correcting device of the present embodiment. As shown in FIG. 2A, the electronic component main body 10 has a plurality of electronic components 11 stacked in a vertical direction (two) and a parallel direction (11 rows) in a housing. Each electronic component 11 has a plurality of terminals 11a. Further, as shown in FIG. 2B, each electronic component 11 is arranged via a plate 12 for radiating heat generated from each electronic component 11. Examples of such an electronic component body 10 include an inverter used in a hybrid vehicle, for example.

  As shown in FIG. 2A, the board 1 is assembled to the electronic component main body 10, and each terminal 11a is disposed at a position of the board hole 1a that is substantially opened in the corresponding board 1. Yes. However, the terminal 11a cannot be inserted into the board hole 1a even if the board 1 is to be assembled to the electronic component body 10 as it is. This is because a plurality of electronic components 11 are stacked via the plate 12, so that the position of the terminal 11 a is displaced from the normal position due to the dimensional error of the electronic component 11 itself or the plate 12. . Therefore, the position correcting device according to the present invention that corrects the position of each terminal 11a to a regular position is used.

  Hereinafter, this position correction apparatus will be described in detail. FIG. 2 is a view showing an assembling table 20 on which the electronic component main body 10 is placed and the driving of the comb template 30 is guided when the position of the terminal 11a of the electronic component main body 10 is corrected. As shown in the figure, the assembly base 20 drives a pedestal 21 on which the electronic component main body 10 is placed and a comb template 30 to be described later, so that the comb template is set between the terminal rows of the electronic component main body 10. It is comprised from the guide part 22 which guides the drive of 30. FIG. Furthermore, the guide part 22 has a box-like shape composed of three surfaces (22a, 22b, 22c). As will be described later, the movement of the comb template 30 is controlled on the basis of these three surfaces. The reason why the vicinity of the center of the left surface 22b is opened is that the comb template is slid sideways using a cylinder or the like, as will be described later, so that it is necessary to pass the cylinder or the like.

  FIG. 3 is a diagram showing the electronic component main body 10 set on the pedestal 21. Thus, when the electronic component main body 10 is set on the pedestal 21, each electronic component 11 and the plate 12 are already arranged at predetermined positions in the casing in the previous process.

  FIG. 4 is a view for explaining the configuration of the comb template 30. FIG. 4A is a diagram showing a state where the comb template 30 is set between the terminal rows in a state where the electronic component main body 10 is set on the assembly base 20. As shown in the figure, the comb template 30 is in a state in which the two comb portions 32a and 32b, the holding portion 31 that supports the two comb portions 32a and 32b, and the two comb portions 32a and 32b are closed. Or it is comprised from the clamp part 32c fixed in the open state, and the control part 32d which controls opening and closing of the comb-shaped parts 32a and 32b.

  The two comb-shaped portions 32a and 32b overlap each other and have protrusions 32a1 and 32b1 that form combs. The protrusions 32a1 and 32b1 extend from the base portions 32a3 and 32b3, respectively, and the number of adjacent protrusion sets corresponds to the number of terminal rows. The thickness of the two comb-shaped portions 32a and 32b overlapped is equal to or less than the length of the terminal 11a. As will be described later, this is because each terminal 11a is inserted into the substrate hole 1a in a state in which each terminal 11a is sandwiched between the protrusions 32a1 and 32b1. The clamp part 32c slides or fixes the comb-shaped parts 32a and 32b by a predetermined distance horizontally by rotating a knob. The predetermined distance by which the comb portions 32a and 32b are movable is determined by the restricting portion 32d. That is, the restricting portion 32d restricts the movable distance in the lateral direction of the comb portions 32a and 32b when the clamp portion 32c is released, and prevents it from moving in other directions. The contact surfaces of the adjacent protrusions when the comb portions 32a and 32b are closed by the clamp portion 32c correspond to the positions in the parallel direction of the substrate holes 1a when the substrate 1 is assembled. As will be described later, when the comb portions 32a and 32b are set between the terminal rows, or when the terminal 11a is sandwiched between the protrusion portions 32a1 and 32b1, the clamp portion 32c is operated.

  Further, two cylinders (moving in the vertical direction and the horizontal direction) for moving the comb template 30 itself are connected to the holding portion 31 as will be described later. The width of the holding portion 31 and the width of the guide portion 22 are slightly larger than the width of the guide portion 22. The reason for this will be described when a method for correcting the position of the terminal 11a using this position correction device is specifically described.

  FIG. 4B is an enlarged view of the protrusions 32a1 and 32b1 as viewed from above (enlarged view of a dotted line portion in FIG. 4A). As shown in the figure, the protrusions 32a1 and the protrusions 32b1 are alternated. Furthermore, FIG.4 (c) is an enlarged view of the dotted-line part of FIG.4 (b). For convenience of explanation, the terminal 11a and the substrate hole 1a are also shown in FIG. As shown in the figure, a V-shaped groove 32a2 is formed in the protrusion 32a1 at a position corresponding to the substrate hole 1a, whereas no groove is formed in the protrusion 32b1. Since the protrusion 32a1 has the groove 32a2, when the terminal 11a is sandwiched between the protrusions 32a1 and 32b, the terminal 11a can be corrected to the position of the groove 32a2, that is, the normal position in the vertical direction.

  FIG. 4D is a diagram of the protrusions 32a1 and 32b viewed from the front (a diagram viewed from the arrow direction in FIG. 4B). In addition, the terminal 11a is also shown in the figure for convenience of explanation. As shown in the figure, the thickness of the protrusion 32a1 is offset in the direction of the protrusion 32b1 (in reverse terms, the thickness of the protrusion 32b1 is offset in the direction of the protrusion 32a1. ). Such a structure can be realized by forming the protrusion 32a1 thicker in the direction of the comb 32b than the thickness of the base 32a3 of the comb 32a. This is to prevent the terminal 11a from being bent when the terminal 11a is sandwiched between the protrusions 32a1 and 32b.

  Next, a method for correcting the position of the terminal 11a of the electronic component main body 10 to a regular position using the above-described position correction device will be described with reference to the flowchart of FIG. First, in step S10, the electronic component main body 10 is set on the base 21 (see FIG. 3). Next, in step S11, the clamp part 32c is operated to open the mold parts 32a and 32b, and the clamp part 32c is operated again to perform clamping in the opened state. Next, in step S <b> 12, the protrusions 32 a 1 and 32 b 1 are set between the rows of terminals 11 a of the electronic component main body 10. Specifically, first, the left surface of the holding portion 31 of the comb template 30 is moved to the inner surface 22 a in a state where the left surface is in contact with the left surface 22 b of the guide portion 22. This movement is performed by the cylinder 41 or the like. As described above, the width of the holding portion 31 is slightly smaller than the width of the guide portion 22, and the left surface of the holding portion 31 is in contact with the left surface 22 b of the guide portion 22 in this way. This is because the terminals 11a are placed on the approximate center line. That is, when the left surface of the holding portion 31 is brought into contact with the left surface 22b of the guide portion 22, each terminal 11a is designed in advance so as to be approximately on the center line of the adjacent protrusion. In addition, the term “substantially on the center line” means that when a plurality of electronic components 11 are stacked as described above, the position of each terminal 11a is displaced, and for a certain terminal row, on the center line between adjacent projections. This is because there is a slight deviation from the center line with respect to other terminal rows. However, by setting the protrusions 32a1 and 32b1 so that the terminals 11a forming each row are on the substantially center line between adjacent protrusions, all the terminals 11a can be reliably connected between adjacent protrusions. Can be set. Thereafter, the comb template 30 is slid sideways by the cylinder 42 or the like until it contacts the right surface 22 c of the guide portion 22. This is for bringing the terminal 11a into contact with the protrusion 32a1. That is, when the comb template 30 is brought into contact with the right surface 22c of the guide portion 22, the widths of the comb template 30 and the guide portion 22 are designed so that the terminal 11a comes into contact with the protruding portion 32a1. As described above, the left surface 22b of the guide portion 22 is opened by a predetermined range so that the cylinder 42 and the like pass.

  Next, in step S13, the clamp portion 32c is operated by an arm type machine or the like to slide the projection portion 32b1 to the left to sandwich each terminal 11a. In this state, the clamp portion 32c is operated again to perform clamping. As a result, each terminal 11a is corrected to a proper position. FIG. 6 is a diagram showing this state, where FIG. 6A is a perspective view, FIG. 6B is a plan view, FIG. 6C is a side view, and FIG. 6D is a terminal 11a. It is an expanded side view of the place which pinched | interposed in protrusion part 32a1, 32b1.

  Next, in step S14, each terminal 11a is inserted into the corresponding substrate hole 1a. Thereafter, in step S15, the clamp portion 32c and the cylinders 41 and 42 are operated to remove the comb template 30 from the electronic component main body 10, and the series of operations is completed. In the subsequent process, the electronic component main body 10 and the substrate 1 are soldered to the terminal 11a through the substrate hole 1a, and the assembly process of the electronic component main body 10 and the substrate 1 is completed.

  As described above, the position correction apparatus according to the present embodiment uses the comb template 30 so that all the terminals 11a can be placed at regular positions simultaneously even when the electronic components 11 having a plurality of terminals 11a are stacked vertically and horizontally. Can be corrected. Thereby, the board | substrate assembly | attachment of the laminated | stacked electronic component can be performed efficiently. Further, the position of the terminal 11a having a small length can be corrected by reducing the thickness of the protrusions 32a1 and 32b1 (see FIG. 6C).

  Note that the terminal position correcting device in the board assembly according to the present invention is not limited to this embodiment, and various modifications may be made without departing from the spirit of the apparatus. For example, in the present embodiment, the electronic component main body 10 in which the terminals 11a are regularly stacked has been described. However, the present invention can be applied even when the terminals are irregularly arranged vertically and horizontally. However, in this case, the shape of the protrusions 32a1 and 32b1 (the number of grooves and protrusions, the interval, the length, etc.) so that the terminal holes are sandwiched between the protrusions 32a1 and 32b1. Need to be changed accordingly.

  In this embodiment, when the terminals 11a are sandwiched between the protrusions 32a1 and 32b1 in step S12 described above, the terminals 11a are once brought into contact with the protrusions 32a1 having the grooves 32a2, and then the protrusions 32b1 are slid. I was pinching. However, conversely, after each terminal 11a is once brought into contact with the protrusion 32b1, the protrusion 11a having the groove 32a2 may be slid to sandwich each terminal 11a. Or after setting each terminal 11a on the approximate center line of adjacent protrusion, you may make it slide and pinch both protrusion part 32a1, 32b1.

  In this embodiment, the groove 32a2 formed in the protrusion 32a1 has a V shape. However, the shape is not limited to this as long as the position of the terminal 11a can be corrected in the vertical direction. Alternatively, it may be semicircular. Furthermore, in this embodiment, the groove 32a2 is formed only in the protrusion 32a1, but the groove may be formed in the protrusion 32b1. In this case, it is effective when the cross-sectional shape of the terminal is circular as shown in FIG.

  Further, in the present embodiment, when the comb portions 32a and 32b are stacked from the beginning and set between the terminal rows, they are slid by the cylinder 41 or the like from the same direction. However, when the comb-shaped portions 32a and 32b are separately provided and set between the terminal rows, they may be set by sliding from opposite directions as shown in FIG. In this case, a cylinder or the like to be driven for each comb part 32a, 32b and a guide part for determining the position are required.

  The protrusions 32a1 and 32b1 may be coated with Teflon (registered trademark) or the like. This can prevent the terminal 11a from being damaged when the terminal 11a is sandwiched.
