Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tool for inserting and extracting electronic components such as ICs onto and from a printed circuit board, and particularly relates to a simple tool for inserting and extracting electronic components using a motor.

Conventionally, electronic components such as a 40-pin IC package were inserted into a printed board and then removed from the printed board by hand or with a flat screwdriver. It was extremely difficult to remove the pin terminal, and the pin terminal had problems such as being bent diagonally or breaking.

The present invention has been made in view of the above-mentioned drawbacks.
We propose a new electronic component insertion/extraction tool that grips both longitudinal ends of an electronic component, such as an IC package, and vertically removes it using a motor.
Briefly stated, the present invention is a tool for inserting and extracting electronic components into and out of a component mounting surface of a printed circuit board or a socket mounted on a printed circuit board, and which has a motor at its upper end that can change the direction of rotation. A rotary shaft provided therein, a movable body screwed onto the rotary shaft so as to be movable up and down in the component insertion/extraction direction in the axial direction, and an intermediate portion thereof pivotally supported on both left and right sides of the movable body. The legs can be freely opened in a direction perpendicular to the component insertion/removal direction, and the upper part from the pivot point is a handle part for opening the legs, and the lower part is provided with a claw for hooking the package of the electronic component at the tip, and serves as a package holding part. a pair of left and right clamping fittings, a holding plate that is provided between the package holding parts of the pair of holding fittings and presses the upper surface of the held electronic component; a presser member comprising a movably supported guide pin and a spring inserted into the guide pin and resiliently applied between the guide pin and the inner surface of the package holding portion to apply a pressing force to the presser plate; It is located between the package clamping parts of the pair of clamping fittings and has a U-shaped cross section, and the horizontal part of the U-shape is movably supported by the lower end of the rotating shaft and guides the guide pin through it; Protection by surrounding and guarding both sides of the electronic component held by the holding plate and the holding fitting by opposing vertical parts having a U-shaped cross section, and by standing the tool upright against the component mounting surface of the printed board or the top surface of the socket. It is characterized by having a member.

Embodiments of the electronic component insertion/extraction tool according to the present invention will be described in detail below with reference to the drawings.

IC package cage, 4 is a motor 5 equipped at one end
The rotation direction of the motor 5 can be freely selected using a rotation switching lever 51.
6 is a movable body that is screwed into the thread groove 41 of the rotating shaft 4 and can be raised and lowered in the axial component insertion/extraction direction according to the rotation of the rotary shaft 4; A package cage holding part 71 having a claw at the lower part of the shaft supporting point and a handle part 72 for opening the legs and a spring 73 at the upper part.
They are a pair of clamping fittings. 9 is a pair of clamping fittings 7
The electronic component 3 is located between the package holding portions 71 of
For example, this is a presser member that biases the IC package in the component insertion/removal direction with a spring, and includes a presser plate 91 that presses the top surface of the IC package 3, and a presser plate 91 that is vertically disposed on the upper surface of both ends of the presser plate 91, and presses the presser plate 91 against the package holding portion 7.
An elastic force is generated between the two guide pins 92 movably supported in the component insertion/extraction direction with respect to the package holding part 71, the locking pin inserted into the guide pin 92 and provided at the intermediate part of the pin, and the inner surface of the package holding part 71. It is composed of a spring 93 that applies a pressing force to the pressing plate 91. Reference numeral 8 denotes a protection member for the IC package 3 provided between the package clamping parts 71 of the pair of clamping fittings 7. and a protective device 82 having a U-shaped cross section. U-shaped protective equipment 8
2 slightly protrudes on both sides of its horizontal portion to serve as a guide 83 for the package holding portion 71, and has two holes in the horizontal portion for passing through and guiding the two guide pins 92, and are opposed to each other. The two vertical parts surround and guard both sides of the electronic component held by the holding plate 91 and the clamping fitting 7, and the part mounting surface of the printed board 1 or the socket 2,
That is, the insertion/extraction tool is configured to stand upright on the top surface of the IC socket.

Now, in such a configuration, when inserting the IC package 3 into the IC socket 2 on the printed board 1, first hold the movable body 6 of the insertion/extraction tool with your left hand so as not to rotate it, and then move the motor 5 so that it can be operated in a straight direction. Hold the motor 5 with your right hand and move the motor 5 to the movable body 6.
When the movable body 6 rotates in the downward direction, the clamping fitting 7 pivotally supported by the movable body 6 descends together with the movable body 6.
This operation is continued until the tip of the claw portion 71 of the clamping member 7 protrudes from the lower end of the protector 82 of the protection member 8. In this protruding state, the knob portion 72 of the clamping fitting 7 is pressed in the direction of arrow A against the spring 73, and the claw portion 71 is opened in the direction of arrow B using the shaft hole 61, which is pivotally supported, as a fulcrum. , its open claw part 7
1 to the longitudinal base of the IC package 3, and then release the knob 72. As a result, the claw portion 71 clamps the IC package 3 due to the tension of the spring 73. However, in the state where the lever is clamped, the switching lever 51 is operated to switch the motor 5.
is rotated in the opposite direction to the above, that is, in the direction of raising the movable body 6, and is raised until the tip of the pin terminal of the IC package 3 is slightly above the lower end of the protector 82. As a result, the IC package 3 engages the claw portion 71 of the clamping fitting 7 within the protector 82.
Since it will be held by the holding plate 91, the motor 5 is temporarily stopped at this point. After that, align the pin terminals of the IC package 3 with the holes of the IC socket 2 to be inserted, and then insert the lower end of the protector 82.
Place it on both ends of the top surface of IC socket 2, and
is rotated again in the direction in which the movable body 6 descends. As a result, the clamping metal fitting 7 descends in the direction of arrow C, and the spring 93 is initially compressed by the inner surface of the clamping metal fitting 7 while being pushed gently through the holding plate 91, and finally reaches the stepped portion of the guide pin 92. The inner surface of the clamping bracket 7 directly pushes the clamping bracket 7 (if the guide pin 92 does not fit the clamping bracket 7 loosely, it pushes the shaft end surface), and the presser plate 91 presses the
The IC package 3 will be pressed, and the pin terminals of the IC package 3 will be inserted into the IC socket 2. Subsequently, when the movable body 6 is lowered, the IC package 3 is attached to the IC socket 2 as desired, and after the attachment, the lowering force acts to compress the spring 93 via the clamping fitting 7. However, the repulsive force of the spring at that time pushes up the clamping fitting 7. As a result, the claw portion 71 of the clamping fitting 7 opens in the direction of arrow B, and the IC
Move away from package 3, and now IC package 3
The insertion will be completed. In this case, the movable body 6
It goes without saying that the work must be carried out with the handle pressed downward by hand.

The procedure for inserting the IC package 3 into the IC socket 2 has been described in detail above, but when removing it, as well as when inserting it, first press the claw part 71 of the clamping fitting 7 of the insertion/extraction tool.
The tip of the protector 82 protrudes from the lower end of the protector 82 of the protector 8. Then, after opening the claw portion 71, both side edge portions of the IC package 3 inserted into the IC socket 2 are held. Furthermore, if the motor 5 is subsequently rotated in a direction to raise the movable body 6, the clamping fitting 7 will be pulled up together with the movable body 6 in a substantially parallel state, and the IC package 3 will be pulled out from the socket 2. Become. During this time, the lower end of the protector 82 is in a state of pressing against both ends of the upper surface of the IC socket 2.

In this embodiment, insertion and removal of a 40-pin IC package 3 has been described in detail, but the invention is not limited to 40 pins.

As is clear from the above description, the electronic component insertion/extraction tool according to the present invention facilitates the insertion and subsequent removal of electronic components from a printed circuit board, significantly improves work efficiency, and prevents damage to mounted electronic components. The additional effect of reducing the risk of injury can also be expected.
