Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a component separator for a printed circuit board,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a component separating apparatus for a printed circuit board, and more particularly, since components separated from a printed circuit board on which a plurality of components are mounted are easily sorted and discharged, To a component separating apparatus for a printed circuit board.

2. Description of the Related Art Generally, electric / electronic products including mass production and mass consumption include printed circuit boards (PCBs), printed circuit board assemblies (PCBAs) ) Is inevitably used.

As global resource depletion becomes serious, the industrial activities of mass production, mass consumption and mass disposal of electricity, electronic waste are attracting attention as a circulating resource as a solution to depletion of natural resources. Printed circuit boards for signal processing of electronic circuits are essentially used for wastes of electronic and electrical products that are disposed of in large quantities. In addition, printed circuit boards are also being generated in large quantities as waste.

The printed circuit board is composed of a substrate and a plurality of components attached to the substrate. The substrate generally comprises about 30% of a substrate made of polyethylene (PE), polypropylene (PP), polyester and polycarbonate, (Fe), Ni (Ni), Sn (Sn), lead (Pb), aluminum (Al) and zinc (Zn) Zn) and about 30% of noble metal components such as gold (Au), silver (Ag), and palladium (Pd). In particular, printed circuit boards contain between 300 and 600 mg of gold (Au) and 2000 to 3000 mg of silver (Ag) per kg, which is much higher than the amount of gold in the actual gold ore is about 7 mg / Kg . Therefore, techniques for recovering and recycling the same have been actively proposed.

Currently, the process for recovering precious metals from printed circuit boards is usually carried out by injecting the printed circuit board with the concentrate in a high-temperature melting furnace of a non-ferrous smelter. In this case, the remaining molten metal excluding gold, silver and copper is included in the slag and is lost because it can not be recovered. Therefore, a technique for separating parts from a current printed circuit board has been developed, but it has a disadvantage in that parts can not be easily separated from a double-sided or small-sized printed circuit board. In order to compensate for these drawbacks, it is necessary to develop a technology for separating parts from a small printed circuit board and to develop a device so as to increase the application range by pretreatment technology that can maximize the metal recovery rate by separating the components mounted on the printed circuit board.

Conventional techniques developed therefor can be roughly classified into six types.

1. The method of using ultraviolet rays and vibrator, the printed circuit board should be used in a limited manner according to the device specifications, and it is troublesome for a person to directly separate desired parts by using a computer and a CCD (Charge-Coupled Device) .

2. Infrared ray and impact, and 3. Heat and shear force, respectively, to separate components mounted on a printed circuit board by infrared or heated impact or shear force. Both of these methods have a large installation apparatus since the transfer line and the removal line must be separately constructed. In addition, there is a further need for a separate component and a device for collecting the printed circuit board separately.

4. The method of using the metal peeling roller has the disadvantages of the above 2 and 3, and additionally, only the cross-sectional process is possible on both sides of the printed circuit board.

5. A method using a polishing apparatus, a large amount of dust is generated by the polishing action, and in the case of a small component, polishing with the substrate is difficult and recovery is difficult. Also, it is difficult to process printed circuit boards on both sides.

Finally, 6. Using both hot air and centrifugal force, it is possible to treat printed circuit boards on both sides, but it has a low throughput by sheet processing and there is a limit on the thickness of the processable printed circuit board.

The developed techniques have a disadvantage in that the number of parts recovered from the printed circuit board is not continuous, and the type and size of the printed circuit board are subject to a disadvantage.

In order to solve such a problem, JP-A-10-0421591 is disclosed as an example of prior art documents.

This patent discloses a rotor having a conical or quadrangular conical protruding sensor mounted on the center of rotation, a plurality of extending members extending in the horizontal direction from the conical protruding sensor, a plurality of studs mounted on the extending member, A cylindrical case for housing the rotor therein, and a plurality of studs mounted on the inner surface of the cylindrical case.

However, this conventional technique has a problem in that a plurality of parts separated from the printed circuit board and the printed circuit board are mixed and discharged while the lower part is opened and discharged. Therefore, it is cumbersome to further divide the printed circuit board and a plurality of parts which are mixed and discharged.

In addition, there is a growing demand for a technique for efficiently separating components mounted on a small printed circuit board of a small electronic product such as a cellular phone.

Patent No. 10-0421591

Fig. 6 is an enlarged cross-sectional view showing a state in which a printed circuit board is subjected to a frictional force and a shearing force in the component separating portion according to Fig. 1; Fig.

A component separating apparatus 100 for a printed circuit board according to an embodiment of the present invention includes a first feeder 110 into which a printed circuit board 200 on which components are mounted is inserted, A screw shaft (not shown) which is provided on a driving shaft 134 of the driving unit 130 disposed in the driving unit 130 and transfers the printed circuit board 200 inserted into the first feeder 110 to be discharged in one direction by the rotation of the driving shaft 134, The second feeder 120 and the drive shaft 134 provided with the second feeder 120 are disposed along the longitudinal direction of the drive shaft 134 and the printed circuit board 200 transferred by the second feeder 120 is transferred A component separating part 140 for separating the component 220 mounted on the printed circuit board 200; A heating unit 150 disposed along the longitudinal direction of the component separating unit in a state spaced apart from the component separating unit 140 and applying heat to the printed circuit board 200 flowing into the component separating unit 140, And a discharge unit 160 through which the component 220 is discharged.

The printed circuit board 200 to be supplied to the first feeder 110 may include electronic components used in electronic equipment and may be connected to a plurality of components 220 by mechanical means or solder Respectively. At this time, the printed circuit board 200 may be crushed to a predetermined size in a state where the component 220 is mounted, or may be inserted into the first feeder 110 in a finely cut state.

The first feeder 110 may have a funnel shape and may be disposed above the second feeder 120. The printed circuit board 200 to be fed into the first feeder 110 is one in which a large or medium printed circuit board is first crushed or a small printed circuit board is crushed finely. The printed circuit board 200 inserted into the first feeder 110 may have a size that does not pass through the second outlet 141c of the component separating unit 160, which will be described later. The feeding path of the printed circuit board 200 inserted into the opening formed in the upper portion of the first feeder 110 and discharged to the opening formed in the lower portion of the first feeder 110 is the same as the feeding path of the second feeder 120, Or may be formed in a direction different from the conveying path of the printed circuit board 200 conveyed by the component separating unit 140. [ In the embodiment of the present invention, the feed path of the printed circuit board 200, which is inserted into and discharged from the first feeder 110, is fed by the second feeder 120 or the component separator 140 And is formed in a direction perpendicular to the conveyance path of the PCB 200 to be conveyed.

The second feeder 120 is communicably connected to an opening formed in the lower portion of the first feeder 110 and the printed circuit board 200 discharged through the opening is connected to the first feeder 110 through the first separator 130, Lt; / RTI > Here, the transport path through which the shredded printed circuit board 200 reaches the second feeder 120 from the first feeder 110 may be formed in a vertical direction. The shredded printed circuit board 200 is transferred from the second feeder 120 to the first discharge portion 161 of the discharge portion 160 to be described later via the component separating portion 140, May be formed in the horizontal direction.

The apparatus for separating parts of a printed circuit board according to the present invention includes a conveying path through which a printed circuit board 200 fed into the first feeder 110 reaches the second feeder 120, The conveying path through which the printed circuit board 200 arriving at the first discharging unit 120 reaches the first discharging unit 161 via the component separating unit 140 is orthogonal to each other. This is because a conveyance path in which the printed circuit board 200 fed into the first feeder 110 reaches the second feeder 120 and a conveyance path in which the printed circuit board 200 arriving at the second feeder 120 When the conveyance paths reaching the first discharge portion 161 via the component separating portion 140 are communicably connected in the horizontal direction, the overall length of the component separating apparatus 100 of the printed circuit board is relatively long It can be long.

Here, the second feeder 120 may be implemented as a screw-shaped blade. The screw-shaped vane may be fixedly mounted on the drive shaft 134 of the drive unit 130 or may be integrally formed with the drive shaft 130 on the outer surface of the drive shaft 130. The second feeder 120 may be fixedly mounted on a separate rotary shaft (not shown) separate from the driving shaft 134 of the driving unit 130. In this case, the separate rotation axis and the drive shaft 134 of the drive unit 130 may be connected to each other by a chain, a belt, or the like, and may be rotated by the rotation of the drive shaft 134.

The second feeder 120 transfers the printed circuit board 200 discharged through the opening formed in the lower portion of the first feeder 110 in one direction, that is, the direction in which the component separator 140 is disposed .

The driving unit 130 may transmit power to the drive shaft 134 provided with the second feeder 120 to rotate the second feeder 120. The driving unit 130 may be installed inside the component separating apparatus 100 of the printed circuit board. The driving unit 130 includes a driving motor 131, a first pulley 132 connected to the driving shaft 131 and rotated, and a second pulley 132 fixed to one end of the driving shaft 134. [ A second pulley 133 connected to the first pulley 132 and the second pulley 133 to rotate the second pulley 133 by rotation of the first pulley 132, And a belt 135 for rotating the driving shaft 134. [ That is, the driving motor 131 is a driving source for rotating the second feeder 120, and can be driven by a power source supplied from the outside.

The first pulley 132 is installed at the end of the drive motor 131 and is rotatable. Specifically, the first pulley 132 is installed on a rotating shaft formed on the driving motor 131 and receives power from the rotating shaft to rotate. The first pulley 132 is primarily rotated by the drive motor 131. The second pulley 133 is spaced apart from the first pulley 132 and is rotatable with the first pulley 132. The second pulley 133 has the same height as the second feeder 120. This is because the drive shaft 134 formed on the second feeder 120 is fixed to the second pulley 133 without eccentricity.

The drive shaft 134 is fixed to the second pulley 133 and is rotated in one direction by the rotation of the second pulley 133. One end of the drive shaft 134 is fixed to the second pulley 133 and the other end of the drive shaft 134 is fixed to a portion of the first discharge port 141b to be described below .

The belt 135 connects the first pulley 132 and the second pulley 133 and transmits the rotational force of the first pulley 132 to the second pulley 133. Although the present invention is exemplified by the belt 135 for driving the conveyance of the second feeder 120, it can be changed to other structures as well as to a chain or the like as far as it can drive the conveyance of the second feeder 120 .

The component separating unit 140 is provided on a driving shaft 134 provided with the second feeder 120 and can receive the PCB 200 transferred by the second feeder 120. That is, the second feeder 120 may be provided in a part of the driving shaft 134 in the longitudinal direction, and the component separating part 140 may be provided in the remaining part. The component separating unit 140 may include a case 141 and a brush 142. The case 141 may be formed in a cylindrical shape, and the driving shaft 134 may be disposed therein. A spiral steel wire 141d may protrude from the inner surface of the case 141. The brush 142 may be provided on the driving shaft 134 and rotated together with the driving shaft 134.

The printed circuit board 200 on which the component 220 to be separated is mounted can be received in the case 141 of the component separating unit 140 and transferred to the brush 142. In addition, when the printed circuit board 200 is being conveyed in the case 141, frictional force may be transmitted or received by the steel wire 141d. In addition, the component 220 can be separated from the printed circuit board 220 by receiving external force by the brush 142. That is, the printed circuit board 220 can be transported by the brush 142 inside the case 141, and can also receive external force from the brush 142 and the steel wire 141d during the transportation And can be separated from the component 220 by being received.

The spiral wire 141d can adjust the feeding speed of the printed circuit board 200 according to the pitch or angle. This is because it is possible to prevent the parts 220 from being separated from the printed circuit board 200 housed in the component separating part 140 like the control part 170 described below This is to increase the recovery rate of the parts by adjusting the reception time.

The brush 142 may be provided on a drive shaft 134 disposed inside the case 141. The brush 142 may be made of steel or plastics, and may be provided at a predetermined interval along the longitudinal and circumferential directions of the drive shaft 134. The brush 142 contacts the printed circuit board 200 transferred inside the case 141 to sweep the surface of the printed circuit board 200 so that even the small component 220 can be removed from the printed circuit board 200 ). ≪ / RTI > For reference, in the embodiment of the present invention, the brush 142 applies an external force to the surface of the printed circuit board 200, but the present invention is not limited thereto. That is, instead of the brush 142, a plurality of blades (not shown) may be disposed at regular intervals in the longitudinal direction and the circumferential direction of the drive shaft 134.

The brush 142 is preferably provided on the driving shaft 134 with a length sufficient to contact the steel wire 141d protruding from the inner surface of the case 141 of the component separating part 140. [ That is, when the driving shaft 134 is rotated, the brush 142 may be rotated along the driving shaft 134 while being in contact with the steel wire 141d of the case 141. At this time, the printed circuit board 200, which is introduced into the case 141 by the second feeder 120, can receive the external force from the brush 142, and the component 220 can be separated. In addition, since the printed circuit board 200 can be moved in the direction of the inner surface of the case 141 formed with the steel wire 141d by the brush 142, the wire 141d and the brush 142 The component 220 can be efficiently separated from the printed circuit board 200 by cooperation with the printed circuit board 200.

Meanwhile, as shown in FIG. 3, the brush 142 may be provided in the longitudinal direction of the drive shaft 134 over the entire length thereof. When the brush 142 is provided over the entire length of the driving shaft 134, the brush 142 may have a screw shape. As described above, the brushes 142 may be disposed on the drive shaft 134 at regular intervals along the circumferential direction of the drive shaft 134, and may be disposed radially or symmetrically with respect to the drive shaft 134 . The shapes, the number, and the like of the brush 142 may have various shapes depending on the required component separating efficiency.

An inlet 141a through which the printed circuit board 200 to be fed by the second feeder 120 can be introduced may be formed at one end of the case 141. [ The case 141 has a first outlet 141b through which the printed circuit board 200 can be discharged and a second outlet 141 through which the component 220 separated from the printed circuit board 200 can be discharged. (141c) may be formed. The first outlet 141b may be formed on the opposite side of the inlet 141a, that is, the other end of the case 141. The second outlet 141c may be formed between the inner surface of the case 141 and a steel wire 141d formed along the longitudinal direction of the case 141. [ That is, the second outlet 141c may be formed in a plurality of portions of the case 141 where the steel wire 141d is not formed.
The plurality of brushes 142 provided on the driving shaft 134 are connected to the driving shaft at one end and extended toward the direction in which the plurality of second discharging ports 141c are formed. This is because the component 220 separated from the printed circuit board 200 can be guided along the projecting direction of the brush 142 by the brush 142 and can be easily discharged to the second outlet 141c Because.
The first discharge port 141b may be connected to the first discharge port 161 of the discharge unit 160 and the second discharge port 141c may be connected to the second discharge port 141c of the discharge unit 160 And may be connected to the discharge portion 162 in a communicable manner.
The first discharging unit 161 may receive the printed circuit board 200 discharged through the first discharging port 141b and guide the printed circuit board 200 to the outside of the component separating apparatus 100 of the printed circuit board.
The second discharge unit 162 is disposed at a lower portion of the component separating unit 140 and can receive and collect the component 220 discharged through the second discharge port 141c.
Here, the size of the second outlet 141c may be smaller than the size of the printed circuit board 200. This is to prevent the printed circuit board 200 with the component 220 from passing through the second outlet 141c and flowing into the second outlet 162. The second outlet 141c is preferably formed between the spiral steel wires 141d.
The case 141 of the component separating unit 140 may be rotated in the rotational direction of the drive shaft 134 or in the opposite direction to the rotational direction of the drive shaft 134, As shown in Fig. This is because the brush 142 provided on the drive shaft 134 is disposed on the surface of the printed circuit board 200 in a direction opposite to the direction of movement of the printed circuit board 200, So as to easily separate the component 220 mounted on the printed circuit board 200 by applying an external force. The configuration in which the case 141 is rotated may be connected to a separate driving source (not shown) and rotated by the driving source. Such a configuration can be easily implemented by those skilled in the art, The detailed configuration explanation thereof is omitted.
The brush 142 is rotated by the rotation of the drive shaft 134 when the case 141 is rotated so that the inner surface of the case 141 formed with the steel wire 141d and the second outlet 141c are formed And can be alternately rotated along the inner surface portion of the case 141. [ The component 220 of the printed circuit board 200 can be separated from the printed circuit board 200 primarily by the cooperation of the steel wire 141d and the brush 142, And can be easily introduced into the second discharge port 141c while being pressed by the brush 142 rotating along the inner surface of the case 141 having the second discharge port 141c.
At this time, the length of the brush 142 protruding from the drive shaft 134 protrudes to a length that can be in contact with the steel wire 141d, as described above. On the other hand, as shown in FIG. 3, It is preferable that the length of the brush 142 protruding from the drive shaft 134 protrudes to a length that does not reach the second outlet 141c. This is because the parts separated from the printed circuit board 200 by receiving external force from the brush 142 and the steel wire 141d during the contact of the brush 142 and the steel wire 141d, So as to form a gap that can flow into the discharge port 141c.
When the brush 142 and the steel wire 141d are brought into contact with each other as the driving shaft 134 and the case 141 are rotated, the component 220 is separated from the printed circuit board 200 And when the brush 142 is rotated along the inner circumferential direction of the case 141 in which the second outlet 141c is formed, the component 220 is rotated to the second outlet 141c And such a process can be repeatedly performed inside the case 141. In this case,

The heating unit 150 is disposed in the longitudinal direction of the case 141 in a state of being separated from the case 141 of the component separating unit 140, that is, in the feeding direction of the printed circuit board 200 accommodated in the case 141 As shown in FIG. Accordingly, the heating unit 150 can heat the case 141 to heat the printed circuit board 200 conveyed inside the case 141. The heating unit 150 may be an infrared heater (IR heater) or the like.

The heating unit 150 applies heat to the solder until the solder is melted to easily separate the component 220 coupled to the printed circuit board 200 from the printed circuit board 200 do. The heating unit 150 may be heated to a temperature higher than the melting point of the solder so that the solder can be melted and heated to a temperature at which the printed circuit board 200 is not burned or damaged. For example, the heating section 150 can be heated to 250 DEG C or higher. The heating unit 150 can be controlled so as to maintain a temperature higher than the melting point of the solder and prevent the damage of the printed circuit board 200. [

The heating unit 150 is connected to the first outlet 141b of the component separating unit 140 through which the printed circuit board 200 is discharged from the inlet 141a of the component separating unit 140 into which the printed circuit board 200 is introduced It is preferable that the temperature is controlled so as to become lower. This is because the mounting state of the component 220 mounted on the printed circuit board 200 flowing into the inlet 141a of the component separating part 140 is hard and the product is heated to a high temperature. However, after solder is melted to some extent, The solder may be melted when the heating unit 150 is heated to a middle temperature or a low temperature because the bonding state of the solder 220 is weakly deformed. Therefore, the heating unit 150 not only minimizes unnecessary heat but also can be used for a long time.

The heating unit 150 is disposed above the case 141 of the component separating unit 140 to apply heat to the case 141. However, But may be arranged in various forms as long as it is capable of transmitting heat to the printed circuit board 200 via the heat-dissipating unit.

That is, the heating unit 150 may be arranged to surround the outer surface of the case 141 of the component separating unit 140. Accordingly, the heating unit 150 disposed along the entire circumferential direction of the case 141 can heat the printed circuit board 200 evenly, thereby melting the solder.

The discharge unit 160 includes a first discharge unit 161 communicably connected to the first discharge port 141b of the case 141 and a second discharge port 161 connected to the second discharge port 141b of the case 141 And a second discharge portion 162 communicably connected to the second discharge portion 141c.

The printed circuit board 200 from which the component 220 is detached can be discharged to the first discharge portion 161 through the first discharge port 141b. The component 220 may be disposed in the second discharge portion 162 through the second outlet 141c.
The first discharge portion 161 and the second discharge portion 162 may have a funnel shape and the second discharge portion 162 may be disposed below the case 141 of the component separating portion 140 .

One end of the first discharge portion 161 may communicate with the first discharge port 141b of the component separating portion 140 and the other end may be exposed to the outside. The printed circuit board 210 discharged from the first discharging unit 161 may be separated and separated from the first discharging unit 161 in a separate arrangement in the downward direction. The second discharge portion 162 may be longer than the length of the component separating portion 140. This is to prevent a plurality of components 220 discharged through the second outlet 141c of the component separating unit 140 from falling to the outside.

The control unit 170 is disposed apart from the driving unit 130 and can control the driving of the driving unit 130 and the temperature of the heating unit 150. The control unit 170 may be disposed on the upper part of the component separating apparatus 100 of the printed circuit board and spaced apart from the upper portion of the driving motor 131 of the driving unit 130.

The controller 170 controls the driving of the driving unit 130. The controller 170 controls the rotation of the second feeder 120 and the brush 142 that are driven by the driving unit 130, Can be controlled.

As described above, since the component separating apparatus 100 of the PCB according to the embodiment of the present invention can effectively separate the components 220 attached to the PCB 200, the separated components 220 And the printed circuit board 210 can be recovered, respectively, so that the metal recovery rate can be higher than that of the printed circuit board 200 in which the components 220 are not separated.

One embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention to various shapes. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
