The conventional PCB stacking box has a stacking box for vertically stacking PCBs by stacking PCBs vertically or by forming V-shaped longitudinal slots.

However, the PCB stacking type box has a drawback that it is highly likely to cause warping of the PCB during the loading process.

An unloading apparatus for automatically loading a PCB to which the conventional technique as described above is applied includes a conveyor for moving the PCB and an adsorber for adsorbing the surface of the PCB to load the PCB on the loading unit, As shown in Fig.

However, as in the prior art, a configuration in which a surface of a complicatedly wired PCB is adsorbed by an adsorber may cause damage to the PCB itself as well as a method in which a PCB is horizontally adsorbed and stacked There is a problem that it is forced to be loaded.

Another conventional PCB unloading apparatus includes a conveyor for transferring a PCB to an unloading frame between a fixed block and a moving block, and a magazine having a PCB mounted in an unloading frame for accommodating the PCB in a height direction, And the PCBs stacked in the upward and downward directions are stored.

Particularly, in the unloading apparatus of the related art as described above, there is a fundamental problem that the loading unit or the magazine for storing the PCB must be manually inserted into the unloading apparatus in units of one unit at a time, An inefficient process is carried out, resulting in a reduction in productivity.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art,

A step S12 of driving the second transfer part 122 of the first waiting module 120 to place the loading box on the second elevating part 121 and ascending toward the first clamp 123,

A step S13 of lowering the second elevating portion 121 and rotating the pivoting stopper 124 to wait the loading box except for the lowermost stacking box on the first clamp 123,

A step S14 of driving the second transfer part 122 to move the lowermost stacking box and putting it in the third elevating part 131 of the direction switching module 130,

The step S15 of lowering the third lifting part 131 and driving the third-second transfer part 133 to bring the lowermost stacking box into contact with the fourth-1 transfer part 147 of the stacking module 140 ,

A step of driving the vertical movement part 144, the horizontal movement part 143 and the front and rear movement part 142 of the loading module 140 so that the pickup part 145 picks up the PCB and loads it in the slot S of the loading box S16)

Elevating the fourth elevating part 141 and driving the fourth conveying part 148 to place the loading box on the fifth elevating part 151 of the second waiting module 150 (step S17)

A step (S19) of lowering the fifth elevating part (151) and driving the fifth conveying part (152) to convey the stacking box to the discharging module (160)

(S20) of driving the sixth transfer unit 162 to stack the stacking boxes on the sixth elevating unit 161 and stacking the plurality of stacking boxes on which the PCBs are stacked in the reverse order of the stacking order .

Therefore, it is possible to accomplish the objective of automating and streamlining the entire PCB loading process through a series of arrangements in which PCBs are automatically stacked in units of stacking box groups forming PCB slots and transported by one unit and discharged in group units .

An advantage of the present invention is to provide a PCB automatic loading apparatus that mounts a series of structures for simultaneously loading a plurality of stacking boxes at one time and automatically feeding and discharging PCBs fed through a conveyor while transferring the units one by one.

Accordingly, there is an advantage that a vertical slot-type stacking box, which provides relatively stable usability, can be applied, compared to a conventional stacking box in which a PCB is stacked up and down.

Particularly, the present invention differs from the conventional art in that a stacking box is manually inserted in units of one unit, which is different from a configuration which causes inefficiency of a process, so that stacking boxes are stacked in groups of multiple stacks, As PCBs are stacked, they are configured to perform a series of process sequences that are collectively discharged in units of stacking boxes as in the case of input, minimizing the work space as well as improving the productivity by automating and streamlining the entire PCB loading process .

The second transfer part 122 of the first waiting module 120 is driven to place the loading box in the second elevating part 121 and to perform the step S12 to ascend toward the first clamp 123. [

The step S13 of lowering the second lifting part 121 and rotating the pivoting stopper 124 and waiting the state where the loading box except for the lowermost stacking box is mounted on the first clamp 123 is performed.

For example, when the stacking boxes 1 to 5 are stacked from the top to the bottom, the second conveying unit 122 raises the stacking boxes 1 to 5 to the first clamp 123, When the boundary of the second loading box is sensed, the second elevating part 121 stops rising and then falls.

At the same time, when the first sensing means 125 senses the bottom surface of the fourth loading box, the rotation stopper 124 rotates to the bottom side to mount the loading boxes 1 to 4 on the upper side of the first waiting module 120, Only the fifth loading box is lowered so as to be in contact with the second transferring unit 122.

The second transfer section 122 is driven to advance the lowermost stacking box and the step S14 is carried out in the third elevating section 131 of the direction switching module 130. [

That is, the fifth loading box enters the direction switching module 130 via the second conveying unit 122 and the third conveying unit 132, and is placed on the third elevating unit 131.

The step S15 of lowering the third lifting part 131 and driving the third-2 transferring part 133 to bring the lowermost stacking box into contact with the fourth-1 transferring part 147 of the stacking module 140 Conduct.

That is, the third-second transfer unit 133 provided in the direction orthogonal to the third-first transfer unit 132 switches the proceeding direction of the fifth loading box to the one-side loading module 140 of the direction switching module 130 And the 4-1 transfer unit 147 connected to the 3-2 transfer unit 133 is driven and transferred.

A step of driving the vertical movement part 144, the horizontal movement part 143 and the front and rear movement part 142 of the loading module 140 so that the pickup part 145 picks up the PCB and loads it in the slot S of the loading box S16).

That is, the pick-up unit 145 picks up the PCB to be fed horizontally on a conveyor (not shown) provided on one side of the stacking module 140 as shown in FIG. 9 (a) The gripping means 149 is operated so as to take the pickup posture and after the PCB is picked up, the turning means 149b is rotated as shown in FIG. 9 (b) so that the gripping means 149 takes a loading posture .

Since the second sensing unit 146 is provided at the lower end of the vertical movement unit 144 coupled to the pickup unit 145, the pickup unit 145 is moved by sensing the empty slot S of the fifth loading box, do.

A step S17 of raising the fourth elevating part 141 and driving the fourth-2 conveying part 148 to place the loading box on the fifth elevating part 151 of the second waiting module 150 is performed.

That is, since the 4-1 conveying part 147 and the 4-2 conveying part 148, which enter the fifth loading box from the direction switching module 130 to the loading module 140, are provided in directions orthogonal to each other, 2 transfer unit 148 transfers the fifth stacking box with the PCB stacked thereon to the second standby module 150. [

The step S18 of raising the fifth lift part 151 toward the second clamp 153 and entering the entry stopper 154 and waiting the state where the loading box is mounted on the second clamp 153 is performed.

As described above, the first standby module 120 transfers the stacked boxes in the order of the lowest stacking box No. 5 to the first stacking box, and then the stacked boxes are transferred to the second standby module 150. Therefore, The loading unit 151 lifts up the loading box No. 5 in the order of the loading boxes 4 to 1 at the uppermost portion thereof, and mounts the loading box to the second clamp 153.

The third sensing means 155 senses the bottom surface of the loading box supplied to the second clamp 153 by the fifth elevating portion 151 to enter and immobilize the entrance stopper 154 in contact with the bottom surface, The elevating portion 151 descends in an empty state.

The fifth elevating portion 151 is lowered and the fifth conveying portion 152 is driven to transfer the stacking box to the discharging module 160 (S19).

That is, when the first to fifth loading boxes initially loaded in the second waiting module 150 are completely loaded in reverse order, the entry stopper 154 is moved backward and the fifth elevating part 151 is lowered to the upper end And the stacking boxes are transported to the discharging module 160 in a stacked state.

The sixth conveyance unit 162 is driven to place the stacking box on the sixth elevating unit 161 and descend to stack the plurality of stacking boxes on which the PCBs are stacked in the reverse order of the stacking order and perform the step S20. It is possible to streamline the process by collectively discharging the stacking boxes.

The PCB automatic loading apparatus and the loading method using the apparatus according to the present invention as described above are characterized in that a plurality of stacking boxes are simultaneously put in a batch and the PCBs are automatically stacked one by one while stacking the PCBs fed through the conveyor, There is an advantage of providing a PCB automatic loading device for mounting the structure of the PCB.

Particularly, the present invention is different from the conventional art in which a stacking box is manually inserted one unit at a time, thereby differentiating the process from the one that caused the process inefficiency. Thus, the stacking boxes are stacked in multi- PCBs are stacked and transported in units of stacking box groups as in the case of input, so that the entire PCB stacking process can be automated and efficient, resulting in a significant improvement in productivity compared to the prior art It is expected to be.
