The open space of the cylindrical supply cylinder is covered with a protective cover, and the protective cover is made of an untreated material which is free from brittleness or static electricity. The cylindrical supply cylinder is further equipped with a pocket at the end of the component movement track.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The present invention is not limited to these embodiments.

1 shows a method of operating a parts feeder for selecting a defective part according to the present embodiment. As exemplified by S10 to S70, the part feeder operating method is to provide a vacuum pneumatic pressure and air with vibration intensity control to provide an alignment faulty part which may lead to an interruption of the operation of the electronic component production line or the injection operation line or continuous assembly operation line or The efficiency of removal of defective parts is greatly improved, and the reliability of supplying alignment parts is greatly enhanced. Hereinafter, the entire process of the part feeder operating method for selecting the defective part is defined as the defective part sorting mode.

Fig. 2 shows an example of a parts feeder system configuration implemented in the defective-part selection mode according to the present embodiment. As shown, the parts feeder system 500 includes a parts feeder 1, a vacuum pump 90-1 that provides vacuum pressure. An air compressor 90-2 for air injection, a detection sensor 1000 for detecting an alignment state or a defective state of the component 1000, vibration intensity control (for example, level and amplitude and waveform) of the vibrator 20 and The controller 200 in which the vacuum pressure of the vacuum pump 90-1 and the air pressure intensity of the air compressor 90-2 are controlled and on and off are controlled is controlled by a hopper feeder feeder (300).

Specifically, the parts feeder 1 covers the openings of the cylindrical feed cylinder 30 and the cylindrical feed cylinder 30, which are connected by the frame 10 and the fixed block 40 and are subjected to vibration of the vibrator 20, A component discharge guide 50 for discharging the aligned component to the outside and a tilting separator 60 for picking up a defective part by frictional force provided on the component moving track 33 of the track body 31 And a track discriminator 90 provided on the component moving track 33 of the track body 31 for catching a component aligned by vacuum attraction force or for removing a defective component and an inferior component in an alignment state by air jetting.

The parts feeder system 500 includes a frame 10, a vibrator 20, a cylindrical feed cylinder 30, a component movement track 33, a fixed block 40, ) And the controller 200 that controls it is a typical component. For example, it may be a component of a parts feeder and a controller of the prior art of the present invention as illustrated in Patent Document 10-2001-0009649 (Feb. 5, 2001). Particularly, when the amplitude generated from the vibrator 20 is transmitted to the microcomputer by the vibration sensor detection signal provided to the vibrator 20, the controller 200 operates the waveform by comparing the standard amplitude with the standard level through the level controller, And the hopper feeder 300 are connected to the cylindrical feeder 30 and the component discharge guide 60 by the load sensing of the vibrator 20 through the load sensing unit of the microcomputer, . This control means the parts feeder basic control logic of the controller 200. Hereinafter, the parts feeder basic control logic is defined as a part alignment mode.

The protective cover 30-1, the tilt separator 60, the track discriminator 90, the vacuum pump 90-1, and the detection sensor 100 may be provided with a dedicated component to be.

For example, the protection cover 30-1 is made of an uninterrupted material that is not affected by brittleness or static electricity, and the wind (influences of the wind caused by the airbag, the peripheral device, and the environment during the operation of the parts feeder) The component 1000 is prevented from being jammed by the component movement track 33 because the component 1000 is not transmitted to the component movement track 33 of the component 1000. This is because the weight of the component 1000 So that these extremely light parts are not affected by the surrounding environment.

For example, the warp sorting apparatus 60 includes a warp discriminating plate 70 which is located in the intermediate discriminating tool 31-5 and which picks out the defective parts 1000 in the size of frictional force, (Not shown). 3, the slant discriminating plate 70 includes a first friction protrusion 73-1 formed at an intermediate portion, a second friction protrusion 73-1 formed at both right and left sides of the first friction protrusion 73-1, (73-2, 73-3), thereby changing the magnitude of the frictional force due to a change in the area in contact with the part.

For example, the track discriminator 90 is pierced by a guide track 91 connected to the component moving track 33, a discriminating track 93 connected to the guide track 91, and a discriminating track 93, First and second vacuum holes 93-1 and 93-2 for holding the first and second vacuum holes 93-1 and 93-2, an air hole 93-3 for piercing through the selection track 93 to remove defective parts or poorly aligned parts by air jet, A track separator fixing bolt 97 for detaching and attaching the rotary body 90 to the track body 31 of the cylindrical supply cylinder 30 and the controller 200 of the parts feeder 1 to form the first and second vacuum holes 93-1 A vacuum pump 90-1 for supplying vacuum air to the air holes 93-1 and 93-2 of the parts feeder 1 and an air compressor And a detection sensor 100 (not shown) for detecting a bad part or a poorly aligned part passing through the selection track 93 so that the vacuum pump 90-1 and the air compressor 90-2 are controlled on and off by the controller ) .

Particularly in terms of layout, the track discriminator 90 is provided at a position adjacent to the component discharge guide 50. For example, in the track body 31 of the cylindrical supply cylinder 30, an end screen 31-7 is formed at a position where the component outlet 31-3 starts, and the end screen 31-7, Is provided to a portion where the track separator 90 is detached and attached. Therefore, the end screening tool 31-7 is formed with a screw hole into which the track selector fixing bolt 97 is screwed. In addition, the end selection tool 31-7 may have a structure in which the component transfer track 33 is cut to form a component discharge port 31-3 and a stepped cut surface.

Hereinafter, the implementation of the defective-part selection mode according to the present embodiment will be described in detail with reference to FIG. 2 to FIG.

S10 is a step of setting the parts feeder 1. The parts feeder setting includes the vibration intensity data of the vibrator 20, the vacuum pressure intensity of the vacuum pump 90-1, the air injection pressure intensity of the air compressor 90-2, A connection state, a component feed rate of the hopper feed 300, and the like. Therefore, the part feeder setting may be a data item set in the controller 200 or a data item newly set according to the conditions of the operation line, and the setting and inputting of the data item may be performed by a unique Function.

Thereafter, the controller 200 determines whether or not vibration is generated through the vibrator 20 in S20, defective parts recognition in the controller 200 associated with the detection sensor 100 in S30, defective parts removal through poorly sorted parts recognition, The vacuum pressure control of the pump 90-1 and the air injection pressure control of the air compressor 90-2 are performed and the continuous check of the state of the parts of S50 is performed and the vacuum pump 90-1 and the air The control of the parts feeder 1 is stopped by the controller 200 by changing the control of the compressor 90-2 and recognizing the stop of the vibrator of S70.

S20 is a stage in which the vibrator 20 operates. In this case, the controller 200 applies the parts feeder basic control logic to the control of the vibrator 20. The parts feeder basic control logic is the same as the control method of the controller disclosed in the present applicant's patent publication No. 10-2001-0009649 (February 5, 2001), as described above.

The cylindrical supply cylinder 30 is shaken by the vibration intensity applied by the vibrator 20 and the vibration of the cylindrical supply cylinder 30 causes the part 1000 gathered at the center of the track body 31 to move along the component movement track 33 along the spiral path. At this time, the spiral path of the component movement track 33 forms a close-contact surface change section in which the circular component 1000 is set up and laid down again through the entire section to the component discharge port 31-3 at the final end, The component 100 is switched to a state aligned on one side through the surface change period. The spiral path of the component moving track 33 is a component of a conventional part feeder.

In addition, by the function of the tilt separator 60, defective parts using the attraction force are selected by the action of the homologous separator 90 together with the selection of the defective part using the frictional force, thereby discharging the normal state part 1000A to the part discharge guide 50 While the defective-state parts 1000B are collected on the central portion of the cylindrical supply cylinder 30. [

3 (A) shows an interaction state between the steady-state part 1000A and the warp discriminating plate 70. As shown in FIG. The steady state component 1000A positioned in the open type body plate 71 of the inclined discriminating plate 70 enters the open type body plate 71 to form the flat first face 1001, 3 friction surfaces 73-1, 73-2, 73-3 so that the contact surface is maintained as it is, and the contact surface maintenance is achieved by the contact between the front surface 1001 of the steady state component 1000A and the first, -1, 73-2, 73-3). As a result, the steady state component 1000A overcomes the vibration applied with the frictional force of a sufficient size and passes through the first, second and third friction protrusions 73-1, 73-2, and 73-3 to the component discharge guide 50 . On the other hand, FIG. 3 (B) shows the state of interaction between the defective-state component 1000B and the warp discriminating plate 70. As shown in the figure, the defective-state component 1000B positioned on the opening-type body plate 71 of the warp-discriminating plate 70 has the ridge-shaped rear surface 1002 and the first, second and third friction protrusions 73 73-3, 73-3) and the reduced contact surface, and the contact surface reduction is affected by the back surface 1002 of the defective-state component 1000B and the first, second and third friction protrusions 73-1, 73- 2, 73 - 3). As a result, the defective-state component 1000B is in contact with the first, second and third friction protrusions 73-1, 73-2, and 73-3, and the first, second, and third friction protrusions 73-1, -2, 73-3), it is separated from the opening-type body plate 71 by gravity action without being able to overcome the applied vibration. That is, as described in FIG. 3, the defective-state component 1000B has to fall to the gap G between the fixed clamp 80 and the warp discriminating plate 70. 5B, the defective-state component 1000B is positioned at the guided inclined plane 31-5a of the intermediate selector 31-5, and the inclined angle a of the guided inclined plane 31-5a is positioned at a position corresponding to the defective state component The defective-state component 1000B is collected at the center of the cylindrical supply cylinder 30 by allowing the cylinder 1000B to slide by gravity.

Specifically, Fig. 4 (A) shows an interaction state between the steady state component 1000A and the track discriminator 90. Fig. As shown in the figure, the track discriminator 90 operates to apply vacuum pressure to the first and second vacuum holes 93-1 and 93-2 by operating the vacuum pump 90-1, And the steady state component 1000A positioned on the guide track 91 is in a state of being attracted by the vacuum pressure of the first and second vacuum holes 93-1 and 93-2. Then, the steady state component 1000A is affected by the sufficiently strong vacuum pressure through the first and second vacuum holes 93-1 and 93-2 with the structure of the flat front face 1001, Maintains the magnitude of the attraction force formed between the front surface 1001 of the steady-state part 1000A and the selection track 93. As a result, the steady state component 1000A can overcome the vibration applied with a sufficient magnitude of attraction force and can be discharged to the part discharge guide 50 through the sorting track 93. In this case, the detection sensor 100 does not detect a defective part or an alignment defective part for the part 1000 passing the discriminating track 93, so that the controller continues to control the vacuum pump 90-1, The compressor 90-2 is kept in the OFF state. Therefore, no air is injected through the air hole 93-3 connected to the air compressor 90-2.

On the other hand, S30 to S60 represent a quick response mode to a defective part. S30 is a stage in which a quick response is performed by detecting a defective part or an unevenly recognized part recognition under the operation of the parts feeder 1. [ This is achieved when the detection sensor 100 detects a defective part passing through the selection track 93 or a part in a poorly aligned state and the controller 200 recognizes it. Step S40 is a step for removing defective parts or poorly aligned parts passing through the selection track 93. This is because the controller 200 turns off the vacuum pump 90-1 while turning the air compressor 90-2 on So that defective parts or parts in a poorly aligned state are removed from the air jetting track 93. Then, the parts removed from the sorting track 93 are collected at the center of the cylindrical supply cylinder 30 by free fall under gravity.

4 (B) shows the state of interaction between the defective-state component 1000B and the track discriminator 90 and the detection sensor 100. Fig. As shown in the figure, a defective part or an alignment defective part passing through the selection track 93 is detected by the detection sensor 100 as a defective part 1000B, and the controller recognizes the detection signal of the detection sensor 100 Simultaneously generates an air compressor on signal for activating the air compressor 90-2 at the same time as a vacuum pump off signal for stopping the operation of the vacuum pump 90-1. Then, the first and second vacuum holes 93-1 and 93-2 no longer form a vacuum attraction force, whereas the air hole 93-3 is formed in such a manner that the injection of air supplied from the air compressor 90-2 . As a result, the defective-state component 1000B is separated from the selection track 93 by the air injection pressure injected from the air hole 93-3, and is guided by the inclined angle b of the selection track 93 under gravity to the cylindrical supply cylinder 30 As shown in FIG. At this time, when the air injection pressure of the air compressor 90-2 is appropriately adjusted, the vacuum pump 90-1 can be also operated when the air compressor 90-2 is operated. Therefore, the parts feeder is provided with the track discriminator 90 on the path of the component moving track 33 of the cylindrical feed cylinder 30, and the track discriminator 90 is capable of discharging the component 1000A with vacuum suction force The defective state parts 1000B can be collected at the center of the cylindrical supply cylinder 30 without discharging the defective state parts 1000B by the air injection pressure.

Step S50 is a step of confirming whether a normal part is supplied again. This is achieved when the detection sensor 100 detects a normal component 1000 on the selection track 93 and the controller 200 recognizes it. S60 is a stage in which a normal part is supplied again so that the part is discharged to the outside. This is implemented by the controller 200 turning on the vacuum pump 90-1 again while turning off the air compressor 90-2. Then, in the selection track 93, the air injection is stopped and the vacuum attraction force is formed again. As a result, the normal component 1000 passing through the selection track 93 is discharged to the outside through the selection track 93.

On the other hand, in S70, the operation of the parts feeder 1 is stopped by stopping the vibrator, and the control of the controller 200 is also stopped, which means that the parts feeder operating method for selecting the defective part in this embodiment is also initialized.

On the other hand, Fig. 5 shows an example in which the configuration of the parts feeder system of Fig. 2 is modified. As shown in the figure, the parts feeder system 500 includes only the track discriminator 90 without using the tilt separator 60 as in the case of FIG. 2, so that the sorting operation of the parts 1000 can be reduced to one stage. This is because the method of operating the parts feeder for selecting the defective parts of the controller 200 is performed by the air and the vacuum in the track discriminator 90. Therefore, the present invention can also realize the advantage that the parts feeder system 500 can be configured in various ways.

On the other hand, Fig. 6 shows another example in which the constitution of the parts feeder system of Fig. 2 is modified. 2 is different from that of FIG. 2 in that the parts feeder system 500 is constructed by applying the pockets 50-1 capable of performing the same operation without applying the component dispensing guide 60. FIG.

As shown, the parts feeder 1 includes a frame 10, a vibrator 20, a cylindrical supply cylinder 30, a protective cover 30-1, a fixed block 40, a tilt separator 60, (90-1 to 90-9), and a pocket (50-1) to which the aligned parts in the track discriminator (90) are loaded. In this case, the pocket 50-1 is suitable for continuously discharging miniature and minute weight parts in an aligned state like a camera component of a smart phone. Further, the pocket 50-1 forms a bolt hole or a through hole, and is detached and attached to the cylindrical supply cylinder 30 through the bolt hole or the through hole.

As described above, the part feeder operating method for selecting the defective parts applied to the parts feeder system 500 according to the present embodiment is such that the front and back sides of the part 1000 moving along the component moving track 33 are aligned A component alignment mode in which the vibration intensity of the vibrator 20 vibrating the cylindrical feed cylinder 30 is controlled by the waveform of the analyzed vibration, the path of the component movement track 33 to form an attraction force for the component 1000, And a defective part sorting mode in which the defective part is removed by air blowing by sucking the part 1000 with the vacuum pressure supplied to the vacuum cleaner 100. This can lead to the interruption of the operation of the electronic parts production line, It is possible to greatly improve the removal efficiency of defective alignment parts and to greatly increase the reliability of the alignment part supply.
