Description

Clamping Apparatus for Tape feeder

The present invention relates to a clamping apparatus of a tape feeder for clamping vinyl peeled off from a tape of a tape feeder for supplying electronic components in a surface mounter for automatically mounting electronic components on a printed circuit board. The present invention relates to a clamping device for a tape feeder that is variable in order to easily hang the vinyl peeled off the tape when replacing the inserted new tape reel or vinyl recovery reel.

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 mounting of various parts, the mounting precision is high and the mounting of various parts is possible, which has the advantage of being suitable for small quantity production among various types, but has a disadvantage of low productivity due to the low mounting speed.

The surface mounter picks up the mounting parts from the feeder part for supplying the mounting parts, the X-Y table part for determining the working position, the conveyor part for conveying the printed circuit board to be worked on, and the tape feeder, and puts them on the printed circuit board. It consists of the head part etc. which are mounted.

The tape feeder inserts the electronic component into the recess of the tape, tapes the inserted surface mounting component with vinyl, winds the tape on the tape reel, and installs the feeder to supply the electronic component to the surface mounter. Done. At this time, the tape feeder installed in the feeder unit serves to feed the electronic parts so that the tapes are peeled off one by one by taking off the vinyl and the pickers sequentially pick up the electronic parts in the recess groove one by one.

1 is a front view illustrating a tape feeding apparatus of a conventional surface mounter, and FIG. 2 is a perspective view illustrating a state in which a cover is removed from a conventional feeding apparatus.

First, a motor 122 mounted on an intermediate portion of the frame 120 to generate power, a worm 103 connected to a shaft of the motor 122 and rotating as the motor is driven, and the worm 103 The sensor 124 is installed in close proximity to the worm 103 to detect the rotation angle of the motor to control the driving of the motor, and the worm is installed on the frame 120 so that the rotational force of the worm 103 can be switched at right angles. The worm gear 105 to be engaged with the drive wheel 107 provided in the frame 120 to transfer the tape in the direction of the arrow as it rotates while the feed hole 98 formed in the tape 126 is fitted, and the worm A timing belt 109 connected between the pulleys 96 and 97 respectively fixed to the driving wheel 107 of the gear 105 to transfer the driving force of the motor 122 to the driving wheel 107 side, and the tape ( As the vinyl 111 is peeled off from the 126, the picker removes the mounting component inserted into the recess groove 92. Opening 112 formed in the cover to be absorbed and transported, and the bent piece for closing the recessed groove 92 so that the mounting component is not separated from the recessed groove 92 located in the opening during the transfer of the tape 126 An opening and closing plate 113 having a 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 the control board 115 etc. in which the various necessary parts are mounted.

Therefore, in the state in which the cover 110 is opened, the feed hole 98 formed along one side of the tape 126 is inserted into the protrusion 94 of the driving wheel 107, and then the tape 126 is directly under the cover 110. When the cover 110 is closed and the cover 110 is closed, the mounting part in the recessed groove 92 is absorbed by the picker by the picker while the tape 126 is transported by one pitch according to the driving of the motor 122. You can do it.

When a power not shown is applied to the motor 122, the motor 122 is driven to rotate the worm 103. At this time, the rotation angle of the worm 103 is detected by the sensor 124 to transfer the tape 126 by one pitch and stop the driving of the motor 122 at that point.

In this way, when the motor 122 drives the tape 126 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 126 is 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 126 is conveyed by one pitch.

As described above, in the state where the driving wheel 107 is conveyed by one pitch, the opening and closing plate 113 is positioned above 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 accommodated in the concave groove 108 are not separated outward.

When the tape 126 is conveyed one pitch by the above-described operation, and the mounting part in the recessed groove 92 is positioned on the opening 112, the guide groove 114 having the opening and closing plate 113 formed on the cover 110 is formed. Since the opening part 112 is opened by moving in the direction of the arrow along), the picker is able to absorb the mounting parts located in the recessed groove 92 to be mounted on the printed circuit board.

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. ) And the tape 126 is conveyed by one pitch by restarting the motor 122 in the closed state, so that electronic components contained in the recessed grooves 92 of the tape 126 can be sequentially mounted on the printed circuit board. Will be.

At this time, the vinyl 111 peeled off from the tape 126 is wound on a separate vinyl recovery reel (not shown), and the clamping device between the position where the vinyl 111 is peeled off from the tape 126 and the vinyl recovery reel ( If there is no), if the conveying pitch of the tape 126 and the vinyl 111 is slightly different, the vinyl 111 to be recovered is not cut off or peeled off completely, so that the mounting work is stopped, or the recess groove is When the 92 is not opened, the electronic parts cannot be picked, and even if there is a clamping device, it is not variable, so when the tape reel (not shown) is replaced, the vinyl 111 is placed on the vinyl recovery reel (not shown). The work to hang was not easy.

As described above, when supplying or replacing a tape reel in which a tape in which an electronic component is inserted is supplied or replaced, the clamping device is not variable, and thus, the replacement of the vinyl on the vinyl recovery reel is not easy. .

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem in the prior art, so that the roll gear for clamping the vinyl wound on the vinyl recovery reel can be opened and closed when supplying or replacing the tape reel in which the tape into which the electronic component is inserted is wound. It is an object of the present invention to provide a clamping device for a tape feeder configured to be easy to operate.
