Description

Rack for printed circuit board storage rack

The present invention relates to a rack for storing a printed circuit board, and more particularly, to a rack for storing a printed circuit board used for temporarily storing a printed circuit board to be processed in a process of processing a printed circuit board, To adjust the angle of the rack to adjust the angle of the rack.

Generally, when a printed circuit board (PCB) is manufactured, a circuit is formed on a substrate made of an electrically insulating resin, and a plating process is performed after hole processing so as to allow electrical connection between the circuit and the circuit. In order to prevent oxidation of the circuit exposed on the surface of the substrate and to protect the substrate from the external environment, a printing ink (Photo Solder Resist) having a predetermined thickness is applied to the substrate. Finally, the printed circuit board on which the ink is applied is cut into a plurality of sheets and the outer shape is processed.

In this series of processes, the printed circuit board is processed while being inserted and fixed in a rack for storage and transportation. The rack is constructed so that a plurality of grooves are formed on a flat plate-shaped body to insert the printed circuit board.

1 is a perspective view showing a structure of a rack according to the prior art.

The rack R according to the related art includes a rack body 1 of a predetermined type, a support holder 2 extending from both right and left ends of the rack body and detachable from the both side support holders 2, And a substrate insertion member (3) positioned above a predetermined height relative to the substrate (1) and adapted to contact only the lower left and right sides of the printed circuit board which is fitted on the upper surface.

A plurality of slots 32 are formed on the upper surface of the rack body 1 so that the printed circuit board can be inserted into the slots 32 while being vertically or vertically disposed with respect to the paper surface.

However, since the rack R of the prior art is used in a state where the rack body 1 is laid flat against the ground, the printed circuit board inserted in the slot 32 has to stand almost vertically.

In a process of coating or painting a surface of a printed circuit board, it is possible to store the printed circuit board in such a state. However, since the unfixed parts are dropped on the printed circuit board on which the parts before being fixed by soldering or pieces are dropped, There was an inconvenience that the circuit board could not be stored upright.

The rack 100 of the present invention has grip portions 104 protruding slightly above the plane of the loading portion 102 at both ends of the loading portion 102 which is a rectangular flat plate similarly to the prior art embodiment . A plurality of insertion grooves may be formed on the surface of the mounting portion 102 in the width direction to interpose the printed circuit board 5 thereon. In addition, the rack 100 of the present invention can be made of a material such as synthetic resin, metal, or wood, and it is most commonly manufactured by injection molding using a synthetic resin.

As shown in Fig. 4, the insertion groove formed in the width direction is composed of a first insertion groove 102a having a relatively deep depth and a second insertion groove 102b having a relatively shallow depth. Preferably, the first insertion groove 102a and the second insertion groove 102b are alternately formed between the first insertion groove 102a and the second insertion groove 102b. In some cases, one of the first insertion groove 102a and the second insertion groove 102b may be continuously attached.

A thicker printed circuit board 5 is inserted into the relatively deep first insertion groove 102a or the printed circuit board 5 is inserted when the mounting portion 102 is placed close to vertical. A thinner printed circuit board 5 is inserted into the relatively shallow second insertion groove 102b or the printed circuit board 5 is inserted when the mounting portion 102 is placed close to the horizontal. However, the problem of inserting the printed circuit board 5 into the insertion groove is freely determined according to the convenience of the operator.

On the bottom surface of the loading part 102, two pedestals connected to each other are rotatably mounted. By varying the position and angle of the pedestal, the angle at which the rack 100 is raised relative to the ground can be varied.

When the rack 100 is raised from the ground, the lower pedestal 106 is in contact with the ground, and one end of the lower pedestal 106 is rotatably connected to one end of the underside of the loading unit 102. The lower end of the lower pedestal 106 is parallel to the width direction of the loading unit 102 and the other end of the lower pedestal 106 is located at the center of the lower side of the loading unit 102 As shown in FIG.

At one end of the lower pedestal 106, one end of the upper pedestal 108 is rotatably connected to the link rotating shaft 108a. The other end of the upper pedestal 108 is fixed so as not to slip on the bottom surface of the loading part 102. The upper pedestal 108 is fixed between the other end of the lower pedestal 106 and the lower surface of the loading unit 102 to support the bottom of the loading unit 102. Accordingly, the loading unit 102, the lower pedestal 106, and the upper pedestal 108 can be fixed in a triangular shape.

A pair of position fixing grooves 110 are formed parallel to the bottom surface of the loading part 102 in the longitudinal direction. A plurality of grooves are uniformly formed on the ribs protruding from the bottom surface of the mounting portion 102 at regular intervals so that the other end of the upper pedestal 108 is fitted and fixed.

At the other end of the upper pedestal 108, a latching protrusion 108b is formed. As shown in FIGS. 5 and 6, the locking protrusion 108b is a cylindrical protrusion, and the diameter of the cylinder is slightly smaller than the size of the groove of the position fixing groove 110. The locking protrusion 108b is inserted into any one of the grooves formed in the position fixing groove 110 to prevent the other end of the upper pedestal 108 from sliding on the bottom surface of the loading portion 102. [ The user can adjust the angle of the rack 100 while changing the position where the locking protrusion 108b is inserted.

On the side surface of the position fixing groove 110, a release preventing groove 112 is formed to protrude from the bottom surface of the mounting portion 102. The release preventing groove 112 has a predetermined space formed therein and the portion facing the position fixing groove 110 is opened so that the end portion of the engaging protrusion 108b enters the inner space by a predetermined distance. When the other end of the upper pedestal 108 is moved away from the bottom surface of the loading portion 102 because the end portion of the latching protrusion 108b is in the inner space of the release preventing groove 112, And is caught in the ceiling portion of the groove 112. As a result, the other end of the upper pedestal 108 is completely separated from the loading portion 102 and is not released.

Fig. 7 is a perspective view showing a state in which the rack is set up to be relatively close to vertical, and Fig. 8 is a perspective view showing a state in which the rack is set up relatively horizontally.

When the stopper 108b of the upper pedestal 108 is inserted at the bottom of the position fixing groove 110 when the stacking unit 102 is erected with respect to the ground, the inclination of the stacking unit 102 with respect to the ground becomes maximum (See Fig. 7). On the other hand, when the engaging protrusion 108b is inserted in the uppermost position of the position fixing groove 110, the inclination of the loading portion 102 with respect to the ground becomes minimum, 8 shows a state in which the latching protrusion 108b is fitted in the vicinity of the center of the position fixing groove 110. Therefore, Is close to the maximum and minimum median values.

If the components on the printed circuit board 5 are not yet fully secured and can be shaken or dropped off, the mounting portion 102 may be placed as close to a right angle as possible. The printed circuit board 5 inserted into the mounting portion 102 is in a state of being substantially at an angle of 90 degrees with respect to the mounting portion 102. In this case, the printed circuit board 5 is maximally parallel to the ground. Therefore, the non-fixed parts do not fall off or leave the printed circuit board 5.

When the parts are almost fixed, or when the parts that are not easily detached are mounted, the loading part 102 may be brought close to the ground. At this time, the position where the upper pedestal 108 is fixed is raised upward as shown in FIG.

On the other hand, a bottom member 116 having a high coefficient of friction is attached to the bottom surface of the lower pedestal 106 contacting the ground. The bottom member 116 is made of rubber, urethane, silicone, or the like. The high friction coefficient of the bottom member 116 prevents the raised rack 100 from slipping.

9 is an exploded perspective view showing the structure of the rotation indicator, and Fig. 10 is a plan view showing the structure of the display unit.

A rotation indicator 114 is provided on either or both of the two knobs 104 formed on the rack 100.

The rotation indicator 114 is formed in a cylindrical shape so that the user can rotate the rotary knob 114a by rotating the rotary knob 114. The surface of the cylinder is provided with a display portion 114b for printing characters, Of the state. The cylindrical rotation indicator 114 is inserted into a hole formed in a side surface of the handle 104. The display 114b is exposed to the outside through an opening formed in the surface of the handle 104.
