Tape Reel Vinyl Recovery System for Surface Mounter

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape reel vinyl recovery apparatus of a surface mounter for effectively peeling off a vinyl of a tape reel in a surface mounter for automatically mounting a surface mount component on a printed circuit board. Remove the vinyl covering the tape reel of the surface mounter, which allows the picker to pick up the surface-mounted part inserted in the recess of the tape reel while transferring the pitch by 1 pitch. It relates to a tape reel vinyl recovery apparatus of the surface mounter for.

In recent years in the development of electrical and electronic products, the trend has been to increase the density, miniaturization, and diversification of electronic components, and the development thereof is becoming more and more intense.

In particular, Surface Mounting Technology (SMT) using surface mounters for assembly production of printed circuit boards (PCBs) used in electrical and electronic components is being accelerated.

The surface mounter is a core equipment of the surface mount assembly equipment for mounting a surface mounting device (SMD) on a printed circuit board. The surface mounter receives various surface mount components from a component supplyer and transfers them to the mounting position of the printed circuit board. Equipment to be mounted on the substrate.

Types are classified into high-speed machines and general-purpose machines according to their functions. The high-speed machines are configured to assemble many parts in a short time, so the mounting speed is high, which is suitable for mass production, but the mounting precision is low. Since the machine is configured to be suitable for the mounting of various parts, the mounting precision is high and the mounting of various parts is possible.

The surface mounter includes a feeder part for supplying mounting parts (hereinafter referred to as a "tape feeder"), an X-Y table part for determining a working position, a conveyor part for conveying a printed circuit board to be worked on, and a mounting part from a tape feeder. It consists of a head and the like which are picked up in sequence and mounted on a printed circuit board.

The tape feeder is inserted into the concave groove to transfer the tape taped with vinyl by one pitch with the vinyl peeled off so that the picker can sequentially pick up the mounting parts in the concave groove one by one.

First, a motor 102 mounted on an intermediate portion of the first frame 100 to generate power, a worm 103 fixed to an axis of the motor 102 and rotating as the motor drives, and the worm ( The sensor 104 is installed in close proximity to the worm to detect the rotation angle of the 103 to control the driving of the motor, and the worm gear installed to the first frame and engaged with the worm so as to switch the rotational force of the worm in a right direction ( 105 and the drive wheel 107 provided in the first frame 100 to transfer the tape reel in the direction of the arrow as the feed hole 98 formed in the tape reel 106 is rotated, and the worm gear A timing belt 109 connected between the pulleys 96 and 97 respectively fixed to the drive wheel 107 of the 105 to transfer the driving force of the motor 102 to the drive wheel 107 side, and the tape reel ( As the vinyl 111 is peeled off from the 106, the mounting parts inserted into the recess groove 92 are transported. Opening portion 112 formed in the cover so that the suction and transport, and the bent piece 94 for closing the concave groove so that the mounting part is not separated from the concave groove 92 located in the opening during the transfer of the tape reel The opening and closing plate 113 formed therein, a guide groove 114 formed in the cover 110 to guide the sliding of the opening and closing plate, driving means for moving the opening and closing plate forward and backward, and various components necessary for driving the motor. The control board 115 etc. which are mounted are comprised.

Therefore, in the state in which the cover 110 is opened, the feed hole 98 formed along one side of the tape reel 106 is inserted into the protrusion 94 of the driving wheel 107, and then the tape reel 106 is covered by the cover 110. When the cover 110 is closed and the cover 110 is closed, the mounting parts in the recessed grooves 92 are picked up by the picker while the tape reel 106 is transported by one pitch according to the driving of the motor 102. Can be mounted sequentially.

That is, when the power is applied and the motor 102 is driven to rotate the worm 103, the sensor 104 detects the rotation angle of the worm and the tape reel 106 is conveyed by one pitch. Will stop driving.

As such, when the motor 102 is driven so that the tape reel 106 is conveyed by one pitch, the power is transferred to the worm gear 105 engaged with the worm 103 in a state in which power is switched at right angles, thereby being fixed to the worm gear 105. The pulley 96 is rotated and thus the power is transmitted to the drive wheel 107 through the timing belt 109 to rotate the drive wheel 107 so that the tape reel 106 is conveyed by one pitch.

As described above, in the state in which the driving wheel 107 is conveyed by one pitch, the opening and closing plate 113 is positioned on the opening 112 to close the opening 112. Even if an impact due to vibration or the like is applied to the feeder, the mounting parts in the concave groove 108 are not separated outward.

When the tape reel 106 is conveyed by one pitch by the above-described operation, and the mounting part in the recessed groove 92 is positioned on the opening 112, the opening and closing plate 113 is formed in the cover 110. Since the opening 112 is opened by moving in the direction of the arrow along 114, the picker can absorb the mounting parts located in the recessed groove 92 and mount them on the printed circuit board.

In this case, the vinyl 111 peeled off from the tape reel 106 conveyed by one pitch is continuously discharged into the slot 116 of the cover 110 to be wound on a separate bobbin.

In the separation operation of the vinyl 111 as described above, the pulley 96 and the pulley 97 driven by the driving force of the motor 102 are interlocked by the timing belt 109, and the pulley 97 is coaxially installed on the pulley 97. The vinyl 111 is peeled off while the tape reel 106 is moved by the driving wheel 107.

On the other hand, after the mounting part is mounted on the printed circuit board from the recessed groove 92 located on the opening 112, the opening and closing plate 113 is moved to the left side by the driving means and the opening 112 is opened by the opening and closing plate. ), The motor 102 is driven again to transfer the tape reel 106 by one pitch, so that the mounting parts contained in the recessed grooves 92 of the tape reel 106 are sequentially mounted on the printed circuit board. You can do it.

In this case, the driving force of the motor 102 is transmitted to the driving wheel 107 using the worm 103 and the worm gear 105 without using a spur gear.

Because, when using the spur gears, the motor 102 installed in the first frame 100 should be installed in parallel with the axis of rotation of the drive wheel, so that the width of the tape feeder is increased, thereby increasing the width of the tape feeder installed in the surface mounter. This is because the number is limited.

Therefore, in order to mount a large number of components, it is necessary to install several surface mounters, which are expensive equipments, and thus, the power transmission direction of the motor 102 is switched using the worm 103 and the worm gear 105, and then the timing belt 109 is used. To transmit power to the drive wheel 107.

However, the above-described method had to use a pulley as a device for peeling off the vinyl reel during transportation of the tape reel, resulting in an enlargement of the device, complexity, and noise.

In addition, since the position where the tape reel is peeled off due to the structure of the device is peeled off at the initial stage when the tape reel is supplied, the position of the exposed mounting parts before the picker adsorption is changed does not supply correctly because the error occurs. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem in the prior art, and does not use a driving method using a pulley, and at the same time provides a tape reel vinyl recovery apparatus of a surface mounter for miniaturizing and simplifying the apparatus.

In addition, another object of the present invention is to provide a tape reel vinyl recovery apparatus for a surface mounter by peeling the vinyl just before the picker adsorbs the vinyl in the tape reel, the mounting parts can be supplied accurately without leaving the outside. have.

At this time, the vinyl 111 is inserted between the worm gear 46 and the gear 50 to be separated from the tape reel 105 by the rotation operation of the worm gear 46 and the gear 50.

The vinyl recovery apparatus configured as described above, when the tape reel 106 is conveyed and supplied by one pitch, does not immediately collect the vinyl 111 at the time of initial supply, but when the tape reel 106 arrives at the portion where the mounting component is adsorbed by the picker, By driving, before the vinyl 111 is recovered, the mounting part is prevented from being separated to the outside or the position of the mounting part is changed.

Referring to the operation of the present invention made as described above are as follows.

The feed hole 98 formed in the tape reel 106 is fitted into the protrusion 40 formed in the drive wheel 18, and then power is applied to the motor 10.

As described above, the powered motor 10 is driven in the forward direction to rotate the screw shaft 12, and the rotational movement of the screw shaft 12 is transmitted to the slider 16 to be advanced by the set stroke. At this time, the slider 16 is linearly moved by the hinge pin 35 fixedly inserted into the long hole 40.

When the slider 16 is moved forward, the lever 24 coupled to the slider is engaged with the latch wheel 22 to move forward. At this time, the driving wheel 18 fixed to the same shaft 20 as the latch wheel is fixed. It rotates angularly, and thus, the tape reel 106 in which the feed hole 98 is inserted into the protrusion 40 of the driving wheel 18 is advanced in a predetermined amount so that the vinyl covering the tape reel is peeled off and the mounting parts are exposed to the outside.

In the above operation, the lever 24 is pushed by the protrusion 23 formed on the latch wheel 22 in accordance with the counterclockwise rotation of the latch wheel 22 rotatably installed in the first frame 100. 22, the lever 24 moves forward as far as possible to stop and is returned to the initial state by the latch 25, and is caught between the protrusions 23 of the latch wheel 22 to recover the slider 16. The reverse of (22) is prevented.

In this state, when the motor 10 drives in the reverse direction and rotates the screw shaft 12 in the reverse direction, the slider 16 which has been advanced is returned to its original position.

Subsequently, the lever 24 caught on the protrusion 23 of the latch wheel 22 is rotated by the slider 16 and is detached from the protrusion 23 to restore the slider 17. 14) it is gradually restored without sudden return.

At this time, since the latch 25 is sandwiched between the projections 23 of the latch wheel 22 by the link means, the driving wheel 18 is not rotated in the reverse direction and remains in a stopped state. Accordingly, the tape reel 106 is conveyed by one pitch.

As described above, when the tape reel 106 is conveyed by one pitch and positioned at a lower portion where the mounting parts are absorbed by the picker (not shown), the tape reel 106 may be driven by driving the motor 42 installed in the frame 101. By recovering the vinyl 111 of 106, the picker is exposed to absorb the mounting parts, and the vinyl 111 is recovered by the worm gear 46 and the gear 50.

As described above, the tape reel 6 from which the vinyl 111 has been peeled off by the advance of the slider 17 is conveyed by one pitch, and the tape reel 6 is moved forward by the stroke of the slider 17 according to the forward drive of the motor 42. By peeling off the vinyl 111 of the reel 106, the mounting parts contained in the tape reel 106 are prevented from being thrown out through the opening before being adsorbed by the picker, and the position to recover the vinyl 111 is prevented. Even if it is changed, it is possible to recover the vinyl 111 at a desired position by driving the motor 42 when the desired position is reached.

In the present invention as described above, the slider is interlocked according to the driving of the motor, and thus the structure thereof is simplified, and the cost of manufacturing is significantly reduced by removing the device that transfers the tape reel and the vinyl by the pulley.

In addition, after moving the tape reel by one pitch, the vinyl can be recovered at a desired position, thereby stably moving the mounting parts, thereby increasing the effect of preventing separation of the mounting parts and improving productivity.
