Description

Narrow PCB Feeder {SUPPLING DEVICE FOR PRINTED CIRCUIT BOARD}

The present invention relates to a narrow PCB feed apparatus, and more particularly, a PCB feed apparatus having an improved PCB so that a PCB having a narrow width cut to a specification can be easily supplied to a post process for cleaning or the like. It is about the provision of.

In recent years, the PCBs are manufactured in a form having a small width to meet the miniaturization of electrical and electronic related products.These PCBs have a large number of PCBs in a certain size at the time of manufacture and are cut into independent forms at the completion. It is done.

The narrow PCB thus completed is supplied to the apparatus of the post process such as centuries, and the supply of the PCB is performed by a dedicated supply apparatus.

Various types of PCB supply apparatuses have been developed and used in the related art, and a representative example will be described below with reference to FIG. 6.

The feeder 1 to which the prior art is applied is loaded with a product rack 5 to be supplied to the side of the frame 4 having the feed roller 3 in front of the post-process equipment 2 such as a feeder ( 6).

A plurality of suction plates 8 are installed above the loading rack 6 to suck the edges of the PCB 5 below the transfer plate 7, and above and below the transfer plate 7. It is connected to the vertical carrier (9) which can move in the direction.

The vertical transporter 9 is connected to the horizontal transporter 11 so as to reciprocate in the direction of the feed roller 3 along the horizontal guide 10 installed in the transverse direction of the frame 4 while moving in the vertical direction. ) Is adsorbed and moves horizontally to supply the adsorbed PCB.

The PCB feeder to which the prior art as described above is applied is narrow (approximately 3 × 10 cm in width and width) because the PCB is configured to supply large PCBs having a size of approximately 30 cm or more. It is difficult to supply a PC with a size).

For example, when a small number of PCBs are arranged in a single row, the feeder must have a large number of round trips, which is not only a waste of time in supplying a large amount of PCB, but also lowers the supply efficiency.

In other words, in the centuries where the PCB is supplied, it is designed and operated to work (wash) multiple PCBs at once, while the supply unit supplies one small size of PCB at a time, which means that the feeder continues to work for centuries. Since it becomes a form of revolving, the rotation rate of the whole line falls and eventually becomes a cause which reduces productivity.

In addition, although the suckers are arranged in multiple rows in the conventional feeder, the small number of PCBs can be adsorbed and supplied at a time. However, since only one sucker is arranged in one PCB, it is difficult to stably absorb the PCBs.

In addition, since the width of the PCB is always variable according to the specifications of the product, the provision of each supply device according to the type of the PCB to be manufactured causes a waste of unnecessary equipment investment.

In the case of the suction plate constituting the feeding device, when the PCB is adsorbed by being connected to the vacuum means for quickly and stably adsorbing the PCB, it is impossible to reliably separate the PCB in the state of high adhesion force, as well as two through the holes formed in the PCB. Or, the adsorption force is conducted up to three sheets so that two or more sheets are adsorbed and supplied, resulting in a malfunction state in a later process.

As such, when a small amount of PCB is adsorbed and transported, it is cumbersome to separate an additional means for preventing the PCB directly adsorbed under the PCB to be adsorbed. As the structure of the device becomes complicated, problems such as difficulty in manufacturing as well as smooth operation cannot be guaranteed.

In the present invention, to solve the above problems, the frame is provided by installing a feed roller on the rear side so as to transfer the PCB to the post-process equipment, and the PCB to be supplied to the lower side of the frame multi-stage A loading rack provided to be loaded, and a supplier installed above the loading rack to absorb the PCB on the loading rack and feeding the feeding roller to the feed roller. A partition plate for determining between an alignment plate to determine, a finishing plate connected to both sides of the alignment plate, and a plurality of PCBs arranged variably between the finishing plates, and stacking the PCBs behind the alignment plate. A laminated plate provided so that the bottom surface of the laminated plate Value to be lowered and, possible, which in a loaded condition to improve one to readily supply a PCB having a narrow including yisongja that increases as PCB thickness PCB manufacturing process, the overall efficiency of the objectives in order to load the PCB.

The present invention facilitates the supply of the PCB having a small width to the equipment of the post-process, thereby enabling the multi-row supply while actively responding to the PCB being manufactured to be variable in width while eliminating the defect that the multiple sheets are adsorbed and supplied together. It is an invention having various effects, such as maximizing the efficiency of the supply of PCBs, increasing the productivity of the entire PCB manufacturing line, increasing the convenience of users, and securing an external competitive edge.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

It would be natural to be controlled by a controller (not shown).

The upper end of the alignment plate 111 has a spaced portion 117 formed to be inclined in the direction of the feed roller 103 so that the inner end of the upper portion of the PCB 101 to be supplied can be easily separated from the lower portion of the PCB 101. do.

The supplier 130 is composed of a cylinder or a motor and a screw combination, a motor and an EL guide combination or a motor and a timing pulley, a belt combination, etc., the horizontal mover 131 to move horizontally in the direction of the feed roller 103 in the loading rack 110 And a vertical mover 132 connected to the horizontal mover 131 and moving upward and downward in the loading rack 110.

The vertical mover 132 is connected between the support plate 134 which is connected to the supply plate 133 which is maintained at the same width as the width of the mounting rack 110, and fixed downward from both sides of the supply plate 133 downward The shaft 135 is connected freely.

The supply shaft 135 has a plurality of adsorption means 136 for adsorbing the PCB 101 of the uppermost position stacked on the stacking plate 114 at intervals such as to vary in the width direction of the supply plate 133 Do it.

The adsorption means 136 is fixed to the support 137 and the lower end of the support 137 is variably coupled in the width direction of the supply shaft 135, the adsorption plate 138 ) Is fixed to the horizontal support 139 is in contact with the bottom surface of the supply plate 133 to keep the adsorption plate 138 always in a horizontal state.

In the intermediate position of the adsorption plate 138 is provided with an adsorption port 141 having a suction plate 140 for adsorbing the PCB 101 on the laminated plate 114, the rear side of the adsorption plate 138 A spacer 145 is installed to be spaced apart from the inner portion of the PCB 101 at the top of the 114 so that the suction hole 141 can be easily adsorbed.

One or more suction holes 141 may be provided to be fixed to the long hole 146 formed in the suction plate 138 to be controlled by an interruption means such as bolts and nuts while varying with respect to the length of the PCB 101. something to do.

The spacer 145 is installed on the inner upper surface of the suction plate 138, the separation means 147, such as a cylinder that operates in the vertical direction by the oil, pneumatic, and the separation means 147 in the PCB 101 By connecting the separation tip 148 made of a material that does not damage) is configured to be spaced apart upwards of the upper portion of the PCB 101 protruded inward.

Looking at the operation relationship of the narrow PCB supply apparatus 100 to which the technique of the present invention is applied as described above are as follows.

First, when the multiple stacks of the PCB 101 to be supplied to the stacking rack 110 as the post-process equipment 102 are installed above the stacking rack 110, the vertical reciprocating operation in the direction of the stacking rack 110, loading The PCB 101 is supplied by the supplier 130 which horizontally reciprocates between the rack 110 and the feed roller 103 installed at the rear of the supply device 100.

In order to load the PCB 101 to be supplied to the stacking rack 110, the transporter 116 is operated to lower the stacking plate 114, and the PCB 101 is sequentially stacked on the stacking plate 114. Let's do it.

Then, the side of the PCB 101 is aligned by the alignment plate 111, and the PCB 101 is arranged by the plurality of partition plates 113 provided at equal intervals between the alignment plate 111 and the finishing plate 112. The width direction of the alignment is aligned, when the top portion of the PCB 101 is adsorbed by the supplier 130, the laminated plate 114 repeats the operation of ascending by the transporter 116 by the thickness of one PCB 101 do.

The upper portion of the PCB 101 stacked on the laminated plate 114 is maintained in a spaced apart state in the inner direction (feed roller direction) so that the supplier 130 can easily absorb and supply the PCB 101 located at the top. That is, the upper portion of the alignment plate 111 is formed inclined inwardly spaced apart portion 117 so that the PCB 101 that is in contact with the spaced apart portion 117 naturally spaced inwardly by the spaced apart portion 117 Will be.

Of course, if the width of the PCB 101 is variable, it will be natural to be able to actively respond by moving the interval of the partition plate 113 to the width of the variable PCB 101.

As described above, the PCB 101 stacked on the stacking rack 110 and spaced inward from the top end is repeatedly absorbed by the supplier 130 and is periodically supplied to the feed roller 103. Looking at it as follows.

The supplier 130 may move vertically in the direction of the loading rack 110 by the vertical mover 132 and move horizontally in the direction of the transfer roller 103 from the loading rack 110 by the horizontal mover 131. Adsorption of 101 is made by the adsorption means 136 installed on the vertical mover 132.

Initially, the spacer tip 148 of the suction means 136 connected to the supply shaft 135 rotatably installed between the vertical mover 132 and the supporter 134 fixed downward on both sides of the supply plate 133 connected thereto is provided. It moves down to the loaded PCB.

Then, the upper portion of the PCB 101 is inclined by the spacer 145 provided on the side of the suction plate 138 connected to the supply shaft 135 and the support 137 while constituting the suction means 136. By maintaining the ratio as close as possible to the PCB 101 near the suction plate 140 constituting the suction port 141.

At the same time, a vacuum is applied to the suction plate 140 of the suction port 141 and the spaced tip 148 is lifted to adsorb the adjacent PCB 101 and moved in the direction of the feed roller 103 by the horizontal mover 131. Then, by releasing the vacuum of the suction plate 140, the PCB 101 is naturally supplied to the feed roller 103 to fall.

Then, the supplier 130 returns to the initial position and repeats the operation of sucking the uppermost PCB 101 and supplying it to the feed roller 103. In this case, the suction means ( When the 136 arrives at the initial position, the horizontal mover 131 is stopped and the spaced tip 148 of the spacer 145 provided inside the suction plate 138 is in contact with the innermost portion of the PCB 101. .

At the same time the side of the PCB 101 is maintained in the state supported by the spaced portion 117 of the alignment plate 111, the inner side is maintained in a state inclined in the inward direction maintained in the spaced tip 148.

This is because the support 137 holding the suction plate 138 is fixed to the supply shaft 135 while the separation tip 148 is in contact with the inside of the PCB 101, the supply shaft 135 is the supply plate 133 Since the supporter 134 is fixed to the supporter 134 is rotatably installed, when the spacer tip 148 collides with the PCB 101 while returning to the original position, the supporter 134 rotates upward.

At the same time as the spaced apart by the spaced tip 148, the spaced means 147 is operated to pull the spaced tip 148 upwards, so the PCB 101, which was maintained as the spaced tip 148, rises a little further, and the suction plate 140 and At the same time, by applying a vacuum to the sucker 140, it is possible to adsorb the PCB 101 in the proximal position.

Of course, when the adsorption of the PCB 101 is completed, the separation means 147 returns to its original state and is in a standby state for the next operation, and the adsorption plate 138 returns to the position of the window due to its own weight. Since the horizontal holder 139 fixed to the upper side of the plate 138 is in contact with the bottom surface of the feed plate 133, the suction plate 138 is not lowered downward more than necessary to maintain the horizontal state and the transfer roller 103 It will be able to supply the PCB 101 in the) direction.

When the adsorption means 136 also the width of the PCB 101 to be supplied is variable if the support 137 is fixed to the supply shaft 135 by moving in the left and right directions, the width of the PCB 101 Will be able to actively respond to

By repeating the above operation, the multilayer plate 114 adsorbs the multi-layer stacked PCB 101 and supplies it to the feed roller 103, and the suction plate 140 is spaced apart from the PCB 101 positioned at the uppermost stage. Since the adsorption is carried out through the hole formed in the PCB 101, the phenomenon of adsorption and transport to the PCB 101 located below can be completely excluded, thereby providing efficiency of supply.
