1 is a perspective view of a substrate cutting machine that is an example of an electronic tabletop device according to the present invention, FIG. 2 is a schematic side view illustrating an opening / closing mechanism of a door body in the substrate cutting machine of FIG. 1, and FIG. Similarly, it is a schematic plan view.

As shown in FIG. 1, a substrate cutting machine 1 as an embodiment of an electronic tabletop device according to the present invention has a housing in which an opening is formed by removing a part of a front surface , left and right side surfaces, and an upper portion. the body 2, and the longitudinal section is arcuate front portion to block the opening, and a door 3 consisting of a fan-shaped side portions of the left and right is provided to be perpendicular to the front face .
Note that a cutting tool 4 having a cutting blade below the tip, a cutting tool transport mechanism 5 for transporting the cutting tool 4 vertically and horizontally, and a substrate to be cut are provided in the inside of the housing 2, that is, in the operation unit. A cutting jig 6 for mounting and fixing is housed.

  The door body 3 is composed of a front portion having an arcuate longitudinal section and a pair of left and right fan-shaped side portions, and the depth of the side portions, that is, the length corresponding to the fan-shaped radius, The sample placed on the cutting jig 6 and also the cutting jig 6 itself are set so that they can be taken in and out from the side surface.

The depth is affected by the shape of the sample 2 and the cutting jig 6 operated in the housing 2 (substrate cutting machine 1 in the embodiment), but at least the length of the side surface of the housing 2, ie, The depth is preferably 1/2 or more of the depth, and more preferably 0.6 to 0.7 times the depth.

  The door 3 is more convenient for taking in and out of the sample and observing as the front portion is larger. However, if the door 3 is too large, the door 3 is lifted and rotated with the fan-shaped base portion of the side portion as a fulcrum. It cannot be stored in the upper part.

However, since the opening on the front surface is preferably as large as possible, the front surface portion has an arc shape formed by a fan shape with a central angle in the fan shape of 45 ° or more, preferably 60 to 80 °, in the longitudinal section. It is preferable to do.
The door body 3 is provided with a handle 7 for manually opening and closing the door body 3.
Further, an operation panel 8 provided with operation switches, indicator lights and the like is provided below the front surface of the housing 2.

FIG. 2 is a view showing an opening / closing mechanism of the door body 3.
The door body 3 is supported by a shaft S so that a base portion of a fan-shaped side surface portion is supported by a horizontal base portion 21 constituting the housing 2.

A torsion coil spring 21 is attached to the shaft S, and a tip end portion 21a of the shaft S engages with a locking piece 3a provided below a frame 3b on the back side constituting the door body 3, and the engaging piece 3a. Is always biased in the opening direction.
Therefore, when the handle 7 is lifted upward and the door body 3 is operated in the opening direction, the door body 3 starts to move in the opening direction by the biasing force of the torsion coil spring 21, but the weight of the door body 3 itself is relatively small. light case, for example, in the case of 1kg or less, automatically door body simply lifting the handle 7 is moved in the opening direction.

However, when the weight of the door body 3 is about 2 kg, it is difficult to smoothly lift and move the door body 3 with only the urging force of the torsion coil spring 21, and if the urging force of the torsion coil spring 21 is increased, When closing, a strong force is required.
At that time, when a stronger urging force of the torsion coil spring 21, together with the increase in cost, because it provides an unnecessary load on the housing 2, there is a possibility of shortening the life of the equipment.

  Therefore, in the present invention, a well-known spring unit 23 is attached to the support column 22 that is erected on the rear side of the base portion 2 a that constitutes the casing 2, and the distal end portion of the rope 23 a that constitutes the spring unit 23 is attached. The door 3 is always engaged and urged so as to pull the door body 3 in the opening direction.

  When the urging force of the torsion coil spring 21 and / or the spring unit 23 is used and the door body 3 is rotated to about 35 ° around the fan-shaped base portion of the side surface portion that is pivotally supported, in other words, the door body As long as the center of gravity of 3 is close to the front surface of the door body 3, the urging force of the torsion coil spring 21 and the urging force of the mainspring unit 23 work together, and when the rotation exceeds about 35 °, When the center of gravity of the door body 3 moves rearward from a position close to the front surface portion of the door body 3, it is preferable to adjust so that only the urging force of the mainspring unit 23 works.

When the door body 3 is opened and closed by the two types of urging forces, the movement of the door body 3 may become steep and adversely affect the device itself.
Therefore, in the present invention, in order to relieve the movement, an air cylinder 24 is disposed between the support column 22 and the frame 3b of the door body 3, and the urging force is absorbed by a buffer by air pressure. is there.
In addition , it is preferable to adjust the buffering by the air pressure so that it functions when the rotation of the door body 3 exceeds 50 °.

  As described above, the door 3 is always applied with a force in the opening direction by the urging force of the torsion coil spring 21 and the mainspring unit 23.

  On the other hand, when the door body 3 is in the closed state, the latch 25a of the electromagnetic latch device 25 provided on the front surface portion of the base portion 2a of the housing 2 is located at the center inside the frame 3c of the front surface portion constituting the door body 3. It engages with an engagement hole (not shown) formed in the portion.

  The latch device 25 operates in conjunction with a control unit (not shown) that controls the cutting tool 4 disposed in the housing 2 and a cutting tool transport mechanism 5 that transports the cutting tool 4 vertically and horizontally. When the operation is completed, the latch 25a and the door body 3 are automatically disengaged, and when the cutting operation is completed, the door body 3 is automatically moved by the urging force of the torsion coil spring 21 and the spring unit 23. The front part of the housing 2 and the left and right side parts are simultaneously opened.

  Therefore, the sample placed on the cutting jig 6 can be freely taken out in the lateral direction from the left and right side surfaces of the opened housing 2 without being pulled out to the front. Then, after the processed sample is pulled out to the front, the troublesome carry-out (take-out) work of moving in the lateral direction is eliminated, and the carrying work can be performed efficiently.

  The opened door body 3 is manually closed using the handle 7, and the door body 3 that has been manually moved to the opening closed position is automatically engaged with the latch 25a of the latch device 25. The closed state is secured by joining.

The door 3, during the operation of the operation unit, to keep the opening in the closed state, safety of the operator, not preferable from the viewpoint of contamination prevention of the sample.
Therefore , the latch device 25 and the power source are connected by a spring and a relay switch so that the operation unit operates only when the door body 3 is closed by the latch device 25, that is, when the door body 3 is moored to the latch device 25. It is preferable to keep interlocking.

As shown in FIG. 3, the torsion coil spring 9, the mainspring unit 23, and the air cylinder 24 are provided in pairs on both side surfaces.

The electronic tabletop apparatus of the present invention includes a processing machine for drilling a printed circuit board, a cutting / dividing machine that separates a plurality of substrates into a single mounting board, and a printed circuit board. It can be used in a wide variety of industries including electro-related industries because it can increase the opening of the operation section in inspection machines, etc., and improve workability in sample loading and unloading, processing, and inspection.
