Description

Multi-lane part feeder

The present invention relates to a component feeder for moving electronic components from one process to another in a vibrating manner, and in particular, to a component feeder manufactured so that a plurality of electronic components can be moved between each process in a plurality of rows parallel to each other. .

The supply of electronic components between each process is conventionally made by human hands, but is automatically performed according to the trend of automation. Particularly, a piezoelectric or electromagnet coil type vibration-type component feeder has been developed so that the supply quantity and supply speed of electronic parts can be adjusted so that the transfer speed of the electronic parts can match the speed required in the subsequent process.

This vibrating component feeder makes it possible to arrange an array of electronic products to be conveyed at regular intervals due to vibration. In addition, as the size of electronic components becomes more compact and diversified, the vibration control of the vibration-type component supplier is also becoming more sophisticated.

In particular, the multi-row component feeder has a structure in which electronic components can be supplied by forming a plurality of rows parallel to each other according to the need for a subsequent process. Due to the development of such a multi-row component feeder, not only the process speed but also the supply of various parts required in the process can be made at the same time, thereby greatly improving process efficiency.

However, in such a multi-row parts feeder, although each row of the multi-row parts feeder must be driven independently of each other to enable more precise control of the supply of electronic parts, the currently developed multi-row parts feeder is adjacent to vibrations generated from any one row. As a result, the purpose of increasing work efficiency by supplying multi-row parts is severely restricted as a result of disturbing the control of precise parts supply by affecting the heat generated.

Therefore, in order to realize a dramatic increase in the efficiency of supplying parts by providing components independently from each other between a plurality of rows of a multi-row vibrator, development of a technology capable of blocking vibration transmission between rows is urgently required.

Specific structural or functional descriptions presented in the embodiments of the present invention are exemplified only for the purpose of describing the embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. In addition, it should not be construed as being limited to the embodiments described in the present specification, and should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The multi-row component supplier according to the present invention includes a stop assembly, a vibration assembly, and a vibration blocking member 30 installed on the case plate and the stop assembly, as shown in FIG. 2.

As shown in FIG. 2, the stop assembly includes a base 21 having a constant upper surface area formed thereon, a block stage 22 fixedly installed on the upper surface of the base 21, and a stop block installed on the block stage 22 ( 23), a stop-side plate spring 25 that elastically connects the side surface of the stop block 23 and the side surface of the block stage 22, and the stop-side plate spring 25 on the side of the stop block 23 It consists of a stop-side upper mounting bolt 26 to fix, and a stop-side lower mounting bolt 27 to fix the stop-side plate spring 25 to the side of the block stage 22.

However, as shown in FIG. 3, a plurality of vibration assemblies are formed to form multiple rows.

As shown in FIG. 2, the vibration assembly is installed between a variable horizontal bar 11 that is horizontally elongated above the stop block 23, and between a lower portion of the variable horizontal bar 11 and an upper portion of the stop block 23. The vibration module 13 is fixedly installed on the bottom of the variable horizontal bar 11 and is in contact with the vibration module 13 to receive the vibration from the vibration module 13 and transmit the vibration to the variable horizontal bar 11 The column 12 and the vibration module fixing member 14 fixedly connecting the vibration module 13 to the stop block 23, and the side surface of the variable horizontal bar 11 and the upper side of the stop block 23. The vibration-side plate spring 15 is sexually connected, the vibration-side upper installation bolt 16 fixedly connecting the upper part of the vibration-side plate spring 15 and the side of the variable horizontal bar 11, and the vibration-side plate spring ( 15) consists of a vibration-side lower mounting bolt 17 for fixedly connecting the lower part of the stop block 23 and the upper side of the side of the stop block 23, and as shown in FIG. 3, a plurality of installation bolts corresponding to the stop assembly are provided and are arranged parallel to each other. .

The case plate is a plate member coupled to the front and rear surfaces of the stop assembly and the vibration assembly as shown in FIG. 1.

The vibration isolating member 30 is installed on the bottom surface of the stop block 23 in the stop assembly, and attenuates vibration from being transmitted between adjacent stop assemblies.

For reference, the electronic parts feeder moves the product while the flexible plate rotates like a conveyor used in a general factory, and the means corresponding to the conveyor vibrates and slightly bounces off the parts, thereby aligning the electronic parts at regular intervals. By generating vibration in one direction, it acts to advance the electronic component in a certain direction.

At this time, the machine that vibrates the means corresponding to the conveyor is the component feeder according to the present invention. The parts feeder may have one or two rows of parts, or may be a plurality of parallel rows.The parts feeder according to the present invention includes a means corresponding to a lower conveyor so that parts can advance into a plurality of parallel rows. It is a device that has a plurality of devices that vibrate it.

Here, the vibration module 13 for vibrating the means corresponding to the conveyor may be configured in an electromagnet method or a piezoelectric element method.

For reference, in the electromagnet method, when AC power is applied to the coil, it sucks in a part of the phase control part of the (+).(-) pole and releases it in part. Therefore, suction and release are performed twice during one AC cycle. If one cycle of AC power is phase-controlled and applied in an electromagnet-type component feeder as it is, suction and release are performed at twice the frequency of the power supply, and twice as much vibration occurs. This control method is called general radio wave control.

But the vibration. Since the amplitude is remarkably small and practical amplitude cannot be obtained unless it involves resonance, it must be resonated by matching the supplied power frequency and the natural frequency of the vibrator body. Adjusting the natural frequency requires considerable skill to change the strength of the spring. This operation is called "spring adjustment" and is an important and unavoidable part of the work process. In addition, there is a problem that an appropriate adjustment is required for the gap (GAP) between the fixed core and the movable core.

The piezoelectric element method has a very simple structure because it does not have an electromagnet, which is a separate driving source like an electronic type, and uses a bimorph (piezoelectric element) as a support spring directly.

When an alternating voltage is applied to the bimorph's electrode, the support spring itself generates bending vibrations and transports the work on the chute, thus simplifying the structure and operation.

For example, in the piezoelectric type, it bends to the left when the AC power supply is applied with a (+) voltage and is bent to the right when a (-) voltage is applied, so the power cycle and the vibration cycle vibrate in synchronization. That is, if the frequency of the inverter output (controller) is matched with the frequency of the vibrator body, it resonates, so spring adjustment is unnecessary, and even a beginner can simply and easily adjust and use it.

In the multi-row component supplier according to the present invention, the vibration module 13 is shown to use a piezoelectric element in FIG. 2 due to this advantage, but an electromagnet method may also be adopted as needed.

Referring to FIG. 6 for operation of the vibration assembly, when the vibration module 13 vibrates due to the application of a voltage, the vibration vibrates the variable horizontal bar 11 through the vibration transmission column 12. At this time, the vibration of the variable horizontal bar 11 vibrates slightly inclined toward one of both directions in the longitudinal direction, so that the electronic component above the variable horizontal bar 11 advances in any one direction due to acceleration generated by the vibration.

In this case, the vibration of the variable horizontal bar 11 should be performed while being controlled within an appropriate range. Accordingly, both ends of the variable horizontal bar 11 are connected to both sides of the lower stop block 23 by vibrating plate springs 15. Therefore, by holding both ends of the stop block 23, the variable horizontal bar 11 can be vibrated while maintaining the horizontal. At this time, the standard of the vibration side plate spring 15 is carefully selected and installed so that the vibration of the variable horizontal bar 11 does not approach the resonance frequency.

However, the vibration module is also affected by vibration due to the vibration-side plate spring 15. Accordingly, both ends of the vibration module are also connected to the block stage 22 due to the plate spring 25 on the stationary side as shown in FIG. 2.

The two adjacent vibration modules 13 are simultaneously coupled to the upper surface of the same block stage 22, so that the two vibration modules 13 are installed in a form in which any one block stage 22 is shared. In addition, the vibration transmitted to the stop block 23 along the stop-side plate spring 25 is a variable horizontal bar 11 installed on the top of the adjacent block stage 22 through the block stage 22 adjacent through the base 21. ) Can affect.

In particular, since the multi-row component feeder is equipped with a plurality of variable horizontal bars (11), it may be affected not only from the vibration effect of one adjacent side, but also from the other side, and in this case, the vibration is prevented from being carefully set in order to avoid resonance. It does not proceed in the planned direction, and even if there is vibration, the part may stop or the part may be misaligned.

In addition, in the case of transferring only one electronic part between electronic parts arranged in the chute above the variable horizontal bars 11 adjacent to each other and stopping the other, electrons arranged in a row that should not be transferred due to the transmission of vibration. If the parts are moved together, excessive supply exceeding the processing speed in the subsequent process may cause the entire process to stop or cause various problems.

In order to prevent this phenomenon, in the component supplier according to the present invention, a vibration blocking member 30 is installed.

Vibration isolation should be concentrated at the point where vibration is transmitted. Referring to FIGS. 2 and 5, it can be seen that the load is supported by the stop block 23 at a point where a height difference is formed at both ends of the block stage 22 among the top surfaces of the block stage 22. Here, the point at which the height increases due to the step difference at both ends of the block stage 22 will be referred to as a “support step”. Therefore, it is most effective to block vibration between the top surface of the support step and the bottom surface of the stop block 23. Because, not only the contact area between the block stage 22 and the base 21 is too large, but the block stage 22 must be firmly adhered to the base 21, so that the vibration isolating member 30 is the block stage 22 This is because if it is interposed between the and the base 21, it may be difficult to be tightly coupled.

In particular, the vibration isolating member 30 is independently installed on the upper surface of the support step of each block stage 22 as shown in FIG. 3, and the vibration isolating member 30 installed on the upper surface of the adjacent support step is disconnected from each other. It is installed in the form. As a result, vibration transmission between adjacent block stages 22 can be minimized.

Meanwhile, the vibration blocking member 30 may be formed by bonding the upper pad 31 and the lower pad 32, which are two layers of elastic pad-shaped members, to each other, as shown in FIG. 7. In particular, in this case, the upper pad 31 and the lower pad 32 to be bonded are bonded to each other only at the end or the edge, and the area inside the edge or inside the edge excluding the bonded portion is formed in the form of grooves that are recessed to each other, so that there is a space inside. Can be formed.

When formed in this way, when the vibration is transmitted to the vibration blocking member 30, the elastic force is not immediately applied, but the vibration shock is absorbed until the central spaces formed in the form of recessed grooves are in close contact with each other, and after being in close contact with the center By exerting an elastic force on the vibration blocking member 30, generation of another resonance can be suppressed.

In particular, an upper protrusion 311 having a shape protruding downward is formed on the bottom surface of the groove formed in the upper pad 31, and a lower protrusion 321 having a shape protruding upward on the upper surface of the groove formed in the lower pad 32 When is formed, the moment when the grooves of the upper pad 31 and the lower pad 32 become close to each other due to vibration is delayed due to the contraction of the upper protrusion 311 and the lower protrusion 321, and a large vibration degree Can be blocked.

In addition, as shown in FIG. 7, the upper protrusion 311 formed on the upper pad 31 and the lower protrusion 321 formed on the lower pad 32 are alternately disposed, and the gap between the upper protrusions 311 and the lower protrusion The spacing between 321 is made larger than the diameter of the lower protrusion 321 and the diameter of the upper protrusion 311, respectively.

In this case, the horizontal vibration that generates not only vertical stress but also shear stress in the horizontal direction, the upper protrusion 311 and the lower protrusion 321 are not directly in contact with each other, but a constant time interval is given, so that a large amount of vibration can be absorbed initially. In addition, since the resonance due to the vibration in the shear direction is also disturbed, the vibration in the shear direction can be suppressed as much as possible or almost completely blocked.

Therefore, in the parts supplier according to the present invention, the vibration blocking member 30 is independently arranged in a form disconnected from each other at the most effective position, and the resonance is maximally suppressed not only in the vertical direction but also in the shear direction. Vibration control is possible so that the vibration between each row is blocked in the feeder as much as possible so that the supply of parts can be accurately and effectively.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope of the technical spirit of the present invention. It will be obvious to those who have the knowledge of.
