Conveying system that handles stacked trays at high speed}

The present invention relates to a conveying system for high-speed processing of a component tray containing electronic components and a tray set covered with a top cover on the uppermost layer of the component tray, and more particularly, the top cover covers the tray set introduced into the first module. After being removed by the removal module, a separator separates the stacked component trays individually, and a transfer module quickly transfers the single component tray from a second module to a third module.

In general, electronic components such as display panels are manufactured through devices that perform various processes, and when put into the corresponding work process, a plurality of them are loaded on a tray to prevent transport efficiency and component damage. .

A tray loading device for supplying parts placed inside the tray using the tray as described above receives the tray on which the parts are placed, extracts the parts from the tray where the parts are placed, and discharges the empty tray from which the parts are extracted. The continuous supply of parts means the supply capacity of parts, and the supply capacity may vary depending on, for example, the time when one tray is replaced with another tray or the time when the tray is moved. It is constantly being developed to improve the supply efficiency of parts such as stable supply and shortening the supply period.

In general, a component tray containing electronic components is stacked in multiple layers, and a top cover is covered on the component tray on the uppermost layer to prevent foreign matter from entering the component tray placed on the uppermost layer from causing defects in the electronic component. The top cover is formed in the same shape as the component tray, but is used only for covering the component tray since no electronic component is loaded therein. A multi-layered component tray and a top cover covering the uppermost component tray form a bundle to form a tray set.

A process of removing the top cover from the tray set is required prior to the process of removing the electronic parts loaded inside the part tray from the part tray while the tray set is being transported with the cover tray covered.

Looking at the structure of the tray moving module 20 with reference to FIG. 1 to which the conventional tray moving module is attached, first, in order to adsorb the top cover 12 or the parts tray 11 of the tray set 10, the seat and suction device 27 ) and a movable absorber 22 are provided, the movable absorber 22 is fixed to the movable frame 21 and the movable frame 21 moves up and down in the z-axis direction along the movable lift 23, and the movable lift 23 ) moves along the moving rail 24 in the y-axis, which is the direction of penetrating the ground. For convenience of explanation, the direction away from the line of sight is referred to as +y, and the direction closer to the line of sight is referred to as -y.

In addition, a shuttle plate 26 is provided to transfer the tray in the +y-axis direction, and the shuttle plate 26 transfers the tray while reciprocating in the y-axis direction and returns to the original position.

Looking at the operation of the conventional tray moving module 20, the tray set 10 rises through the tray stacking plate 25, and the tray is adsorbed by the moving adsorber 22 or the seat adsorber 27, and the shuttle plate ( 26) and then transferred in the y-axis direction. At this time, in order to adsorb the trays from the tray set 10, the shuttle plate 26 must be in the +y-axis direction, and in order for the adsorbed tray to be seated on the shuttle plate 26, the shuttle plate 26 must be in the -y-axis direction again. direction, and when the tray is seated, it moves in the +y-axis direction and feeds.

In this way, when the shuttle plate 26 covers the lower tray, adsorption by the adsorbers 22 and 27 is limited, so that when adsorbing the tray of the adsorber, the shuttle plate 26 should be avoided so as not to be covered, and take out the adsorbed tray. Since it has to come back again, frequent movement of the shuttle plate 26 is required. Therefore, there is a problem in that it takes a very long time to transfer the tray and the process is delayed.

Therefore, it is necessary to develop a system for stably transporting the tray while having a simple structure without requiring unnecessary movement of the shuttle plate by overcoming the problems of the conventional tray module.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described so that those skilled in the art can easily implement it.

As shown in FIGS. 1 to 9, the conveying system for processing stacked trays at high speed according to the present invention includes a part tray 11 loaded with electronic parts and a top cover 12 covering the top part tray 11. ) It relates to a system for high-speed transfer processing of the tray set 10 composed of,

A first module 100 receiving a tray set 10 including a plurality of component trays 11 storing electronic components and a top cover 12 covering the uppermost component tray 11;

a second module 200 receiving the tray set 10 from the first module 100 and having a supply lifter 230 for lifting the tray set 10;

A third module 300 receiving the trays transported from the second module 200 one by one and having a discharge lifter 330 for lifting the trays;

a fourth module 400 receiving the tray from the third module 300 and discharging it to the outside;

The cylindrical first rotating body 610 is rotated, and spiral protrusions 620 forming an inclined surface are formed on the outer circumferential surface of the first rotating body 610, and the rotating spiral protrusions 620 rotate the parts tray 11. a separator 600 that is separated from the tray set 10 by being raised; and

and a transfer module 700 that grips the part tray 11 separated by the separator 600 and transfers it to the third module 300.

Referring to FIG. 1 , electronic components are transported in a state in which a plurality of electronic components are loaded on one component tray 11 in order to improve transport efficiency and prevent component damage. A plurality of such component trays 11 are stacked and transported. Since any one component tray 11 is covered by the component tray 11 stacked thereon, it is possible to prevent the penetration of foreign substances and prevent defects in electronic components, The component tray 11 placed on the uppermost layer was exposed to the outside as it was, and foreign substances penetrated into the electronic component, causing defects.

Accordingly, an empty top cover 12, which has the same shape as the component tray 11 but does not load electronic components therein, is covered on the component tray 11 of the uppermost layer. It is transported to a tray set 10 in which a plurality of stacked component trays 11 and a top cover 12 are disposed on the uppermost component tray 11.

In order to take out the electronic components loaded inside the parts tray 11 while being transported by the tray set 10, the top cover 12 is removed, and then the parts trays 11 are put down one by one and the electronic parts therein are taken out. .

The present invention provides a transport system that transports the component trays 11 loaded with electronic components one by one after removing the top cover 12 from the stacked tray set 10 with only a simple structure and configuration.

A transfer system for processing stacked trays at high speed according to the present invention receives a tray set 10 composed of a top cover 12 and a part tray 11 from the first module 100 and moves it to the cover removal module 500. Among the tray sets 10, the top cover 12 is transferred from the first module 100 to the fourth module 400.

The tray set 10 from which the top cover 12 is removed consists of only the parts tray 11 and is transferred from the first module 100 to the second module 200, and the tray set 10 in the second module 200 ) is raised, the uppermost part tray 11 is separated through the separator 600.

The separated uppermost part tray 11 is gripped by the tray clamp 730 of the transfer module 700 and transferred from the second module 200 to the third module 300 . The tray clamp 730 is transported by gripping the side of the component tray 11, so that operations with the separator 600 do not overlap or interfere with each other. Accordingly, an operation of separating the component tray 11 by the separator 600 and an operation of transferring the component tray 11 by the transfer module 700 may be independently performed or may be operated simultaneously.

Therefore, as a more advanced structure than the conventional tray moving module, the operation of separating the uppermost component tray 11 from the stacked component trays 11 through the separator 600, and the separated uppermost component tray 11 The transfer operation from the second module 200 to the third module 300 is performed simultaneously, drastically reducing the time required to transfer the tray from the second module 200 to the third module 300 and process time for handling and processing electronic parts is drastically reduced.

Referring to FIG. 1 , electronic components to be transported according to the present invention are loaded on a component tray 11 . The tray in which the electronic components are accommodated is referred to as a 'parts tray 11'. A plurality of the component trays 11 are stacked, and a tray covering the component tray 11 placed on the uppermost layer is referred to as a 'top cover 12'. The top cover 12 is formed in the same shape as the component tray 11, but no electronic components are loaded therein.

A plurality of stacked component trays 11 and a top cover 12 placed on the uppermost layer are referred to as a 'tray set 10'. In addition, even though the top cover 12 is removed, a plurality of component trays 11 may be referred to as a tray set 10. And, when pointing to either one of the parts tray 11 and the top cover 12, it is referred to as a 'tray'.

Referring to FIG. 2 , the transport system for processing stacked trays at high speed according to the present invention receives the tray set 10 from the outside into the first module 100 and transports it to the second module 200 . However, before transferring the tray set 10 to the second module 200, the top cover 12 disposed on the uppermost layer of the tray set 10 is moved to the fourth module 400 through the cover removal module 500. . Therefore, the tray set 10 transferred from the first module 100 to the second module 200 is in a state in which the top cover 12 is removed.

The second module 200 lifts the tray set 10 received from the first module 100 upward through the supply lifter 230, and the separator 600 disposed on the top of the second module 200 is the uppermost layer. The parts tray 11 is further raised and separated from the tray set 10.

After the transfer module 700 grips the uppermost part tray 11 separated from the tray set 10, it moves from the second module 200 to the third module 300, and the gripped part tray 11 The supporter 800 receives. The supporter 800 is put down again on the discharge lifter 330 of the third module 300, the discharge lifter 330 descends, and the parts tray 11 moves from the third module 300 to the fourth module 400. are transferred

At the same time, the separator 600, which separates the uppermost part tray 11, separates the next part tray 11 again immediately after the part tray 11 is gripped and transported by the transfer module 700 pay Then, the tray clamp 730 of the transfer module 700 returns from the third module 300 to the second module 200, grips the next component tray 11, and transfers it to the third module 300.

The supporter 800 receives the part tray 11 transferred from the transfer module 700 and transfers it to the discharge lifter 330 . Subsequently, the component trays 11 transferred from the transfer module 700 are continuously received one by one and put down on the discharge lifter 330.

The present invention is a system for transferring the component trays 11 placed on the second module 200 to the third module 300 one by one, and the component trays transferred to the third module 300 by the transfer module 700 ( 11) may be transferred from the third module 300 to the fourth module 400 one by one, or may be transferred to the fourth module 400 after being stacked on the discharge lifter 330 by an arbitrary number. The number of component trays 11 stacked in the third module 300 may be variously modified according to the purpose of the process.

In the transfer system of the present invention, in order to transfer the component tray 11 at high speed, the separator 600, the transfer module 700, and the supporter 800 are arranged so as not to interfere with each other, and operate independently of each other, so that very quickly Trays can be transported.

In the conventional tray moving module, depending on whether the shuttle plate is located in the second module 200 or the third module 300, the operation of separating the tray from the tray set 10 or putting down the adsorbed tray has been restricted. In the conveying system of the present invention, the separator 600 and the supporter 800 can operate regardless of the position of the tray clamp 730 of the conveying module 700, so that the part tray 11 is separated from the tray set 10 or Alternatively, the gripped parts tray 11 may be put down.

Therefore, by operating the separator 600, the transfer module 700, and the supporter 800 at the optimal timing, the transfer speed of the trays can be further increased, and the number of trays that can be processed for a certain period of time increases.

And, with reference to FIG. 3, in the first module 100, the second module 200, the third module 300, and the fourth module 400, aligners 130 for aligning the trays before being transferred to the next step may be provided. The aligner 130 strikes the side of the tray so that the position of the tray is aligned without being disturbed or misaligned. As the aligner 130 reciprocates toward the tray, a slight blow may be applied.

In addition, an inclined aligner 900 for aligning the parts tray 11 moved from the second module 200 to the third module 300 by the transfer module 700 is provided as shown in FIG. 9 . The inclined aligner 900 is disposed inclined upward toward the component tray 11 . The component tray 11 transferred to the third module 300 through the transfer module 700 is supported by the supporter 800 but is not aligned. Therefore, the parts tray 11 is aligned through the inclined aligner 900 .

The pad 910 of the inclined aligner 900 approaches the part tray 11 upward from the bottom of the part tray 11 to align the part tray 11 . Before the pad 910 approaches the parts tray 11 (before the extension of the cylinder), the lower end of the pad 910 is positioned at a lower height than the lower end of the parts tray 11, but the pad 910 extends while the cylinder extends. As the pad 910 rises as it approaches the parts tray 11, the bottom of the pad 910 supports the bottom of the parts tray 11 and aligns the parts tray 11 at the time of contact with the parts tray 11. do.

Referring to FIGS. 2 and 3 , the first module 100 is a module that receives the tray set 10 from the outside. The tray set 10 is introduced into the transfer system of the present invention through the first module 100, and the tray set 10 is moved to the first conveyor 110 of the first module 100.

A process of removing the top cover 12 of the tray set 10 in the first module 100 is performed. Accordingly, an aligner 130 and a stopper 120 for aligning the tray set 10 are provided. The aligner 130 strikes and aligns the side of the tray set 10, and the stopper 120 blocks the tray set 10 being transported on the first conveyor 110 so as to stop at a predetermined position. While moving along the first conveyor 110, the tray set 10 is blocked by the stopper 120 and stops at a certain position.

The tray set 10 introduced into the first module 100 from the outside is a tray set 10 equipped with a top cover 12, and after removing the top cover 12 from the first module 100, the second module ( 200), the stopper 120 guides the position of the tray set 10 so that the cover removal module 500 can adsorb and remove the top cover 12. Thereafter, the cover removal module 500 to be described later absorbs the top cover 12 from the first module 100 and transfers it to the fourth module 400 .

The cover removal module 500 absorbs the top cover 12 from the first module 100 and transfers it to the fourth module 400, but if the tray moored in the fourth module 400 remains, the first module It is temporarily mounted on the cover pedestal 140 provided on the upper part of the 100. The cover support 140 supports the side of the top cover 12 .

The second module 200 receiving the tray set 10 from the first module 100 is provided with a second conveyor 210 as shown in FIGS. 2 and 3, and a supply lifter between the second conveyor 210. 230 is provided. The supply lifter 230 moves up and down along the supply lift platform 220 .

Thereafter, in the tray set 10 on which the separators 600 are stacked, the uppermost part tray 11 is raised and separated from the tray set 10 .

The height at which the tray set 10 is raised by the supply lifter 230 is controlled according to values of various sensors that recognize the position and distance of the tray set 10 . When the height of the tray set 10 is high due to the large number of stacked trays, even if the supply lifter 230 rises slightly, the top part tray 11 rises to the height of the separator 600, and the tray set 10 has few stacked trays. When the height of (10) is low, the supply lifter 230 rises a lot so that the uppermost part tray 11 rises to the height of the separator 600.

Therefore, the height of the tray set 10 is recognized through various sensors and the lifting operation of the supply lifter 230 is controlled so that the tray is smoothly transported.

2 and 3, the tray set 10 raised by the supply lifter 230 in the second module 200 is separated from the tray set 10 through the separator 600, and the transfer module 700 The separated component tray 11 is gripped and transferred to the third module 300 .

Then, the discharge lifter 330 descends to the third conveyor 310, and the parts tray 11 passes through the third conveyor 310 to the fourth module 400.

At this time, the number of part trays 11 received by the discharge lifter 330 may be variously modified according to the process situation. For example, the component trays 11 transferred one by one are directly lowered without stacking on the discharge lifter 330 and transferred to the fourth module 400 through the third conveyor 310, or stacked by an arbitrary number After that, the discharge lifter 330 descends, puts it down on the third conveyor 310, and can be transferred to the fourth module 400.

Therefore, if it is difficult for the cover removal module 500 to adsorb the top cover 12 on the first module 100 and put it down on the fourth conveyor 410, the first module 100 or the fourth module 400 The top cover 12 may be temporarily mounted on the provided cover stand 140 .

Referring to FIG. 4 , when the tray set 10 is introduced into the first module 100 , the cover removal module 500 separates and removes the top cover 12 located on the uppermost layer of the tray set 10 . The cover removal module 500 is disposed above the first module 100 and the second module 200 to transfer the top cover 12 from the first module 100 to the fourth module 400 .

In the transfer system of the present invention, the process of removing the top cover 12 of the tray set 10 is performed in the first module 100 . When the tray set 10 is transferred from the first module 100 to the second module 200, the top cover 12 is removed. Accordingly, the second module 200 can directly transfer the component tray 11 to the third module 300 .

Looking at the configuration of the cover removal module 500, a cover removal rail stand 510 disposed to cross the upper portions of the first module 100 and the fourth module 400 is provided. The cover removal rail stand 510 is placed in a horizontal direction. Further, a cover frame 520 reciprocating between the upper portions of the first module 100 and the fourth module 400 along the cover removal rail stand 510 is provided. The cover frame 520 is provided with a lifting cylinder 530 that lifts the rod up and down. At this time, the extension direction of the elevating cylinder 530 is directed downward, and the contraction direction is directed upward. And, the adsorption frame 540 is coupled to the rod side of the elevating cylinder 530. A plurality of adsorbers 550 for adsorbing and holding the top cover 12 are disposed in the adsorption frame 540 . The adsorber 550 adsorbs the top cover 12 using pneumatic pressure.

When the tray set 10 is introduced into the first module 100, the cover frame 520 is located on the upper side of the first module 100 to remove the top cover 12 of the uppermost layer, and the lift cylinder 530 extends. to lower the suction frame 540 to the top of the top cover 12. Then, the top cover 12 is adsorbed and held by the adsorber 550, and the lift cylinder 530 contracts again to lift the top cover 12. And after the cover frame 520 moves along the cover removal rail 510 toward the fourth module 400, the elevating cylinder 530 is extended to lower the suction frame 540 toward the fourth conveyor 410, The adsorption state of the adsorber 550 is released, and the top cover 12 is placed on the fourth conveyor 410.

At this time, when the tray is moored in the fourth module 400, it can be placed on the cover stand 140 provided in the fourth module 400 or the first module 100.

After the tray set 10 is moved from the first module 100 to the second module 200, it rises to the top of the second module 200 through the supply lifter 230. Then, the separator 600 slightly raises the uppermost part tray 11 among the tray sets 10 to separate it from the tray set 10 .

As shown in FIGS. 5 and 6, the separator 600 is disposed in plurality on the upper part of the second module 200, and is located on the side of the part tray 11 when the part tray 11 is raised. arranged to do This position is a space between the plurality of transfer rail units 710. The spiral protrusion 620 of the separator 600 contacts the side end of the component tray 11 to raise the uppermost component tray 11 .

The separator 600 has a cylindrical first rotating body 610, and a spiral protrusion 620 protruding outward is formed on an outer circumferential surface of the first rotating body 610. The spiral protrusion 620 is formed in an arc shape along the first rotating body 610, but is formed in an arc shape in which only a portion is wound, not a shape completely wound by 360°.

The spiral protrusion 620 has a spirally inclined surface formed in the first rotating body 610, and the parts tray 11 rises along the inclined surface of the spiral protrusion 620. That is, when the first rotating body 610 rotates, the spiral projection 620 contacts the side end of the uppermost component tray 11 in the stacked tray set 10, and the component tray 11 rotates the spiral projection 620. ) and is separated from the tray set 10. The inclined surface of the screw protrusion 620 contacts the component tray 11, and the first rotating body 610 does not contact the component tray 11. At this time, a portion where the screw protrusion 620 contacts the part tray 11 is referred to as a separation groove 13 . The separation groove 13 is a stepped groove formed at a position corresponding to the separator 600, and the lowermost surface among inclined surfaces of the spiral protrusion 620 contacts the lower surface of the separation groove 13.

As the first rotating body 610 rotates, the position of the screw protrusion 620 changes. When the screw protrusion 620 is located on the side facing the parts tray 11, the parts tray 11 is in contact with the inclined surface of the screw protrusion 620, and the screw protrusion 620 is on the outside, not the side facing the parts tray 11. , the parts tray 11 is not caught on the separator 600. When the tray set 10 is lifted by the supply lifter 230, the spiral protrusion 620 is positioned so that it faces outward to avoid interference with the parts tray 11, and when the parts tray 11 is located at a certain height By rotating the first rotating body 610 to come into contact with the inclined surface of the screw protrusion 620 and sliding it, the uppermost part tray 11 is lifted and separated from the tray set 10 . The direction in which the first rotating body 610 is rotated rotates in a direction in which the lower surface of the screw protrusion 620 first touches the component tray 11 and then slides toward the upper surface of the screw protrusion 620 .

The separator 600 is fixed in its position without position movement, and only the first rotating body 610 rotates in place by receiving power. The separator 600 separates the uppermost part tray 11 from the tray set 10 regardless of the location of the transfer module 700, and thus, when the transfer module 700 tries to transfer the part tray 11 does not interfere with This is a more advanced structure compared to the prior art, and is possible because the operation and timing of the transfer module 700 and the separator 600 are optimally operated in conjunction with each other, but can be operated independently of each other.

When the uppermost component tray 11 of the tray set 10 is separated from the separator 600 through the separator 600, the transfer module 700 transfers it from the second module 200 to the third module 300. . As shown in FIGS. 5 and 7 , the transfer module 700 of the present invention operates in conjunction with the separator 600 or the supporter 800 to be described later, but the mutual operation does not interfere. Therefore, it operates at the optimal timing capable of quickly transferring the parts tray 11 within a certain period of time. For example, when the transfer module 700 grips and transfers the parts tray 11 separated from the separator 600, the separator 600 transfers the parts tray 11 of the next chapter regardless of the operation of the transfer module 700. An operation of separating may be performed.

Looking at the structure and configuration of the transfer module 700, the transfer module 700 is provided in plural and arranged parallel to each other. A plurality of transfer modules 700 are spaced apart from each other, and the component tray 11 is accommodated in a space between the spaced apart spaces. In addition, a transfer rail stand 710 crossing the upper portions of the second module 200 and the third module 300 is provided, and a transfer frame 720 reciprocating along the transfer rail stand 710 is provided. The power for reciprocating the transfer frame 720 is transmitted from the transfer driver 740 .

Further, a vertical cylinder 760 is vertically coupled to the transfer frame 720, and a horizontal cylinder 750 is coupled to a rod of the vertical cylinder 760. That is, the vertical cylinder 760 moves the rod in the vertical direction, and the horizontal cylinder 750 moves up and down according to the movement of the rod of the vertical cylinder 760.

In the horizontal cylinder 750, the extension direction of the rod is horizontal, and the tray clamp 730 is coupled to the rod of the horizontal cylinder 750. The tray clamp 730 grips the side of the component tray 11 . Operational interference with the separator 600 and the supporter 800 to be described later can be prevented by holding the side of the component tray 11 instead of the tray clamp 730 supporting the lower surface of the component tray 11, Transfer speed can be improved.

Looking at the operation of the transfer module 700, first, the horizontal cylinder 750 extends the parts tray 11 separated from the tray set 10 through the separator 600 so that the tray clamp 730 extends the part tray 11 grip the side of And the vertical cylinder 760 extends to slightly raise the tray clamp 730 holding the parts tray 11, which avoids interference when transferring from the second module 200 to the third module 300. It is for

Then, the transfer frame 720 moves from the second module 200 to the third module 300 along the transfer rail stand 710 . In addition, the vertical cylinder 760 contracts to slightly lower the tray clamp 730 holding the parts tray 11, and the horizontal cylinder 750 contracts to put down the part tray 11 held.

Since the parts tray 11 held by the tray clamp 730 is in a slightly raised state due to the extension of the vertical cylinder 760, the separator 600 and the supporter are transferred from the second module 200 to the third module 300. (800), smooth transfer is possible.

The supporter 800 receives the parts tray 11 from the second module 200 through the transfer module 700 . As shown in FIGS. 5 and 8, the supporter 800 is disposed above the third module 300, and is located on the side of the parts tray 11 in the space between the plurality of transfer rails 710 are placed

The supporter 800 has a cylindrical second rotating body 810 that rotates by receiving power, and a supporting protrusion 830 and an inclined protrusion 820 protrude outward from the outer circumferential surface of the second rotating body 810 is formed The support protrusion 830 is a flat surface that supports the lower surface of the parts tray 11, and the inclined protrusion 820 continues with the support protrusion 830, but the outer circumferential surface of the second rotating body 810 It is formed in a spiral shape along the The support protrusion 830 is disposed at a higher position than the inclined surface of the inclined protrusion 820 . That is, the surface of the supporting protrusion 830 becomes the uppermost end surface, and the inclined surface of the inclined protrusion 820 is inclined so that it gradually descends downward.

When the supporter 800 receives the component tray 11, the support protrusion 830 is first placed in a position to support the lower surface of the component tray 11 so that the component tray 11 is supported. And while the second rotating body 810 rotates, the part in contact with the parts tray 11 moves from the supporting protrusion 830 to the inclined surface of the inclined protrusion 820. At this time, the parts tray 11 is inclined protrusion 820 descends while sliding along the slope of the The lowered part tray 11 is lowered and seated on the discharge lifter 330 that has been raised.

The inclined protrusion 820 is formed in an arc shape along the second rotating body 810, but is formed in an arc shape in which only a portion is wound, not a shape completely wound by 360°. Therefore, when the supporting protrusion 830 and the inclined protrusion 820 are placed in a position facing the parts tray 11, they support the parts tray 11, but the supporting protrusion 830 and the inclined protrusion 820 are part tray 11 ), the part tray 11 falls onto the discharge lifter 330 without being supported by the supporter 800.

First, the support protrusion 830 is positioned toward the parts tray 11 to receive the parts tray 11 from the transfer module 700, and the second rotating body 810 is rotated while supporting the parts tray 11 It is moved from the supporting protrusion 830 to the inclined protrusion 820. The parts tray 11 slides along the inclined protrusion 820 and is seated on the discharge lifter 330 while descending. The direction in which the second rotating body 810 rotates is rotated in a direction in which the surface in contact with the parts tray 11 moves from the supporting protrusion 830 to the inclined protrusion 820 .

The supporter 800 is fixed in its position without position movement, and only the second rotating body 810 rotates in place by receiving power. As a result, after the supporter 800 receives the parts tray 11 from the transfer module 700, the transfer module 700 can operate independently at any position, so that the parts tray 11 can be moved quickly without interference. can handle

Hereinafter, the entire operation sequence of the conveying system for processing stacked trays at high speed according to the present invention will be described.

First, the tray set 10 is brought into the first module 100 from the outside and transported along the first conveyor 110, and then stops at a predetermined position while colliding with the stopper 120 of the first module 100. And aligned through the aligner 130 of the first module (100). At this time, the aligner 130 may be provided in the first module 100, the second module 200, the third module 300, and the fourth module 400, respectively, and the tray moves to the next sequential position. After completion, alignment through the aligner 130 is performed. Also, the parts tray 11 moving from the second module 200 to the third module 300 through the transfer module 700 is also aligned through the inclined aligner 900 .

In a state where the cover frame 520 of the cover removal module 500 is located above the first module 100, the lift cylinder 530 extends to bring the adsorption frame 540 close to the tray set 10, and the adsorber ( 550) to adsorb and hold the top cover 12. Thereafter, the cover frame 520 moves to the fourth module 400 along the cover removal rail 510 in a state in which the lift cylinder 530 contracts and lifts the top cover 12 . Then, the lift cylinder 530 extends and places the adsorbed top cover 12 on the fourth conveyor 410 of the fourth module 400. Then, the top cover 12 moves along the fourth conveyor 410 and is discharged to the outside. At this time, if there is a remaining tray in the fourth module 400, the top cover 12 may be temporarily placed on the cover stand 140 of the first module 100 or the fourth module 400.

The tray set 10 from which the top cover 12 is removed is transferred from the first module 100 to the second module 200 . When the second module 200 receives the tray set 10, the supply lifter 230 is in a lowered state, so that the tray set 10 can be placed on the supply lifter 230.

Then, in order to transfer the component tray 11 from the second module 200 to the third module 300, the supply lifter 230 on which the tray set 10 is seated is raised. The lifting height of the supply lifter 230 is raised to a height adjacent to the screw protrusion 620 of the separator 600 at the uppermost part tray 11 . In addition, the first rotating body 610 of the separator 600 rotates so that the screw projection 620 contacts the separation groove 13 of the component tray 11 on the uppermost layer, and along the inclined surface of the screw projection 620, the parts tray ( 11) slides and rises. As a result, the uppermost component tray 11 is separated from the tray set 10 .

In addition, the horizontal cylinder 750 of the transfer module 700 extends to grip the side of the separated parts tray 11 with the tray clamp 730, and the vertical cylinder 760 extends to grip the part tray 11 raise slightly more. In addition, the transfer frame 720 moves from the second module 200 to the third module 300 along the transfer rail 710 to transfer the component tray 11 . The vertical cylinder 760 and the horizontal cylinder 750 contract so that the parts tray 11 moved to the top of the third module 300 is seated on the supporter 800, and the transfer module 700 moves the part tray 11 release the gripped state. At this time, the rotational position of the supporter 800 is located in the direction in which the supporting protrusion 830 faces the parts tray 11 .

The parts tray 11 is seated on the supporting protrusions 830 of the supporter 800, and the second rotating body 810 rotates while the parts tray 11 slides and descends along the inclined protrusions 820. The parts tray 11 deviated from the lower end of the inclined protrusion 820 is placed on the discharge lifter 330 which is raised. The number of component trays 11 placed on the discharge lifter 330 may be single or stacked by any number.

The discharge lifter 330 receives the component tray 11, descends, transfers it to the third conveyor 310, and transfers it to the fourth module 400. In the fourth module 400, the tray is discharged to the outside through the fourth conveyor 410.

In the transport system for processing stacked trays at high speed according to the present invention, the top cover 12 of the tray set 10 is removed from the first module 100 and then transported to the second module 200 so that the transport module 700 ), it is possible to process the tray with a very rapid operation by transferring the parts tray 11 directly through.

In addition, since the transfer module 700 does not interfere with the separator 600 and the supporter 800 when transferring the part tray 11, it can operate independently, so the part tray 11 ) can further improve the feed rate.

In addition, the separator 600 that lifts the uppermost part tray 11 in the tray set 10 and the supporter 800 that puts the separated part tray 11 down on the discharge lifter 330 do not move and Since it is fixed in place but performs its function only by rotation, the speed of the parts tray 11 is high, and since it can operate regardless of the position of the transfer module 700, a large amount of parts tray 11 can be quickly transferred. .
