Description

[Detailed description of the invention] <Industrial field of application> This invention is used to hold the board slightly floating on a belt conveyor or workbench during the process of mounting circuit elements, etc. on a circuit board such as a printed circuit board. This invention relates to a circuit board holder for holding circuit boards.

<Prior art> In the process of mounting circuit elements on a printed circuit board, conventionally, the printed circuit board is placed on a frame made of wood or the like that has been formed in advance to a predetermined size, and various types of components are mounted on the printed circuit board in this state. Circuit elements are installed by inserting their lead wires into through holes, and then soldering is performed.

<Problem that the invention aims to solve> However, conventional holders for placing circuit boards during the manufacturing process cannot be used when the size of the circuit board changes, or cannot be held securely, so they cannot be used while the circuit board is being moved. There were problems such as circuit boards falling off and being unable to be stacked stably.

<Means for Solving the Problems> The present invention was made to solve the above problems, and provides a circuit board that can securely hold circuit boards during the manufacturing process and that can be stacked stably. The purpose is to provide a holder for

For this reason, in the circuit board holder of the present invention, a rectangular main body frame is formed from a vertical frame and a horizontal frame, the horizontal frame is provided with an engaging part along its longitudinal direction, and two holding frames are provided. is arranged so that it can slide on the horizontal frame by engaging the sliding engagement parts provided at both ends with the horizontal frame, and the sliding engagement part has a hook member that is latched to the engagement part. A turn-shaped clamp is attached, a step is formed on the holding frame to engage the edge of the circuit board, a boss is provided protruding on the vertical frame, and the bottom of the vertical frame corresponds to the boss. It is constructed by providing a hole into which the boss fits.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a perspective view of a circuit board holder. This holder consists of two holding frames 2 and 3 connected in parallel to each other so as to be movable laterally on a rectangular body frame 1. Ru.

The main body frame 1 has a rectangular frame structure in which upper and lower horizontal frames 12 are fixed between vertical frames 11 on both left and right sides, and the vertical frames 11 and horizontal frames 12 are made by drawing aluminum, for example. . Further, the vertical frame 11 is made wider than the horizontal frame 12, and when the main body frame 1 is placed horizontally, the vertical frame 11 is grounded on the stand as shown in Fig. 1, and its upper end is also above the horizontal frame. stand out. An engaging portion 12a having an L-shaped cross section is provided on the outside of the horizontal frame 12 along its longitudinal direction for clamping the holding frames 2 and 3.

Further, a boss 13 is protruded from the center of the vertical frame 11, and a hole 14 into which the boss 13 fits is provided at the corresponding lower surface position. It has a structure in which the holes 14 fit together and can be stacked stably. Further, a square handle hole 11b is provided in the center of the vertical frame 11 to make it easier to hold.

The two holding frames 2 and 3 are formed into a cross-sectional shape as shown in FIG. 3, and step portions 2a and 3a are provided along the longitudinal direction on both upper sides of the holding frames 2 and 3 in order to hold the edges of the circuit board. Further, a similar step portion 11a is also formed inside the upper part of the vertical frame 11.

The holding frames 2 and 3 are connected to the horizontal frame 1 via the sliding engagement part 4.
2 is slidably mounted on. That is, as shown in the cross-sectional view of FIG.
The end portions of the holding frames 2 and 3 are fixed to the upper portion of the sliding engagement portion 4 . Further, a loop-type clamp 5 is attached to the outer side of each sliding engagement portion 4 so that its hook member 6 projects downward and can be rotated up and down. This clamp 5 is installed so as to clamp the sliding engagement part 4 at an arbitrary position on the horizontal frame 12, and its hook member 6 is hooked onto the engagement part 12a of the horizontal frame 12. The clamp 5 is a general-purpose clamp in which a lever is pivotally supported on a base, and a hook member 6 is attached at a position eccentric from the axis of the lever.

When such a holder is used in the process of assembling circuit boards, etc., the holder is placed on a line belt conveyor, etc., and the circuit board 20 is placed on the lower step part 2a, 3a on the holding frame 2, 3. The holding frames 2 and 3 are moved slightly so that the circuit board 20 is sandwiched between the two holding frames 2 and 3, and the hooking member 6 of the clamp 5 is placed on the engaging portion 12a. By hooking and clamping the sliding engagement part 4
is fixed on the horizontal frame 12.

The circuit board 20 is now securely held on the holder and will not easily come off, allowing the circuit elements to be mounted. If the clamp 5 is unclamped, the holding frames 2 and 3 can be easily moved left and right, so even circuit boards of different sizes can be moved.
It can be securely held from both sides and easily held.

After the circuit element mounting work is completed, the holders can be easily stacked with the circuit board 20 held or removed. That is, when a plurality of holders are stacked, the boss 13 protruding from the upper center of the vertical frame 11 fits into the hole 14 drilled at the center bottom of the holder above it, so that the holders do not shift easily. Holders can be stacked on top of each other.

In addition, even in the stacked state, the width of the vertical frame 11 is wider (higher) than the horizontal frame 12, etc., so the elements on the mounted circuit board do not hit other parts, and the holding frames 2 and 3 are Since the clamps 5 for fixing are also placed inside the ends of the vertical frame 11, a plurality of holders can be neatly lined up front, rear, left and right without gaps.

<Effects of the Invention> As explained above, according to the circuit board holder of the present invention, a rectangular main body frame is formed from the vertical frame and the horizontal frame, and the outer side of the horizontal frame is engaged along the longitudinal direction. A mating part is provided, and the two holding frames are arranged so as to be slidable on the horizontal frame by engaging the sliding engaging parts provided at both ends with the horizontal frame, A loop-type clamp having a hook member that is latched to the engaging portion is attached, and a stepped portion is formed on the holding frame for engaging the edge portion of the circuit board, and a step portion is formed on the vertical frame to engage the edge portion of the circuit board. A boss is provided protrudingly, and a hole into which the boss fits is provided at the bottom of the vertical frame corresponding to the boss. Therefore, since the holding frame can be moved and easily fixed with a clamp, circuit boards of various sizes can be sandwiched between the step portions of the holding frame and held easily and reliably. Furthermore, when the holders are stacked, the stacked state can be stabilized by the engagement of the bosses and holes, and since screws and the like do not protrude from the main body frame, the holders can be lined up front, back, left and right without gaps.
