Tape vinyl recovery device of surface mounter

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tape mounter for recovering tapes of a surface mounter for effectively peeling off the tapes of a tape in a surface mounter for automatically mounting surface mount components on a printed circuit board. A surface mounter for recovering the vinyl covering the tape of the surface mounter, which allows the picker of the head to pick up the surface mount component inserted in the recess of the tape while the tape is peeled off while transferring. It relates to a tape vinyl recovery apparatus.

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.

Is a perspective view showing.

First, a motor 102 mounted on an intermediate portion of the frame 100 to generate power, a worm 103 fixed to an axis of the motor 102 and rotating as the motor is driven, and the worm 103 The sensor 104 is installed in close proximity to the worm to detect the rotation angle of the motor to control the driving of the motor, and the worm gear 105 is installed on the frame 100 and engaged with the worm so as to switch the rotational force of the worm in a right direction. ), The drive wheel 107 provided in the frame 100 to convey the tape in the direction of arrow A as the feed hole 98 formed in the tape 106 rotates, and the worm gear 105 A timing belt 109 connected between the pulleys 96 and 97 fixed to the driving wheels 107 to transmit the driving force of the motor 102 to the driving wheels 107 side, and vinyl (from the tape 106); As the 111 is peeled off in the direction indicated by the arrow B, the mounting parts inserted into the recess groove 92 are transferred. Opening 112 formed in the cover so that the beaker (not shown) can be absorbed and transported, and bending to close the recessed groove so that the mounting component is not separated from the recessed groove 92 located in the opening during the transfer of the tape An opening and closing plate 113 having a piece 94 formed therein, a guide groove 114 formed in the cover 110 to guide sliding of the opening and closing plate, driving means for moving the opening and closing plate forward and backward, and driving the motor. It consists of a control board 115 and the like are mounted various components.

Therefore, in the state in which the cover 110 is opened, the feed hole 98 formed along one side of the tape 106 is inserted into the protrusion 94 of the driving wheel 107, and then the tape 106 is inserted into the cover 110. If 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 by the picker while the tape 106 is transported by one pitch according to the driving of the motor 102. It can be mounted.

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 106 is moved one pitch. It will stop running.

When the motor 102 is driven such that the tape 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 so that the tape 106 is fixed to the worm gear 105. The pulley 96 is rotated so that power is transmitted to the drive wheel 107 through the timing belt 109 to rotate the drive wheel 107 so that the tape 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 part 112 to close the opening part 112, and thus the tape feeder during the conveyance of the tape 106. Even if an impact due to vibration or the like is applied, the mounting parts in the recess groove 108 are not separated outward.

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

In this case, the vinyl 111 peeled off from the tape 106 conveyed by one pitch is continuously discharged to the slot 116 of the cover 110 in the arrow B direction and wound on a separate reel (not shown).

As described above, the separating operation of the vinyl 111 is driven by the timing belt 109 in which the pulleys 96 and 97 which are driven by the motor 102 are driven, and a driving wheel is provided coaxially to the pulley 97. As the tape 106 moves by the 107, the vinyl 111 is peeled off in the arrow B direction.

On the other hand, after mounting the mounting component on the printed circuit board from the recessed groove 92 located on the opening 112, the opening and closing plate 113 is transferred to the left by a driving means (not shown) and the opening and closing plate 113 Since the motor 102 is re-driven in the state in which the opening 112 is closed by 1), the tape 106 is conveyed by one pitch, so that the mounting parts contained in the recessed grooves 92 of the tape 106 are sequentially printed. It can be mounted on a circuit board.

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 a spur gear, the motor 102 to be installed in the frame 100 should be installed in parallel with the rotation axis of the driving wheel, so that the width of the tape feeder is increased, thereby increasing the number of tape feeders installed in the surface mounter. Because it 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 during the transfer of the tape, so that the device was enlarged, complicated, and noise was large.

In addition, since the position where the tape is peeled off is peeled off at the initial stage when the tape is supplied due to the structure of the device, there is a problem that an error occurs because the position of the exposed mounting parts is not changed and supplied correctly before the picker is adsorbed. .

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem in the prior art, and the tape of the surface mounter can be supplied accurately without peeling off the vinyl just before the picker adsorbs the vinyl on the tape, so that the mounting parts can be supplied accurately. To provide a recovery device.
