Description

Detailed Description of the Invention Technical Field The present invention relates to an apparatus for transporting and positioning a printed circuit board, and in particular, a device for transporting and positioning a printed circuit board, and in particular for transporting a printed circuit board into a working device that performs some kind of work on the printed circuit board, and positioning the printed circuit board at a predetermined position. This relates to a device for positioning and unloading.

Conventional Technology Work equipment that automatically performs some kind of work on printed circuit boards, such as drilling holes in printed circuit boards, mounting electronic components, or inspecting circuits after mounting electronic components, includes: A printed circuit board transport device and a positioning device are usually provided.

This printed circuit board transfer device generally includes a side frame extending across the main body of the work device in the width direction, a driving rotating body provided at one end of the side frame, a driven rotating body provided at the other end, and It is configured to include an endless belt wrapped around both rotating bodies, and the side frame is used to receive printed circuit boards from other devices such as a printed circuit board supply device, or to pass printed circuit boards to other devices. In most cases, the working device body protrudes a certain amount laterally from both ends of the working device body.

However, when configuring a line by arranging multiple work devices equipped with such printed circuit board transfer devices in a tank, they are separated by a distance twice the length of the sideward protruding portion of the printed circuit board transfer device. In order to dispose the main body of the working device, the length of the line becomes long and a large floor area is required for installation.

When using multiple working devices side by side, the conveying device of the working device located in the middle should hardly protrude to the side of the main body of the device, and the working devices located at both ends should be moved to one side on each side. If only the conveying device is prominent and these are combined, the line can be shortened and the required floor space can be reduced, but in this case, it is necessary to manufacture a working device equipped with three types of conveying devices. Therefore, it is necessary to manufacture four types of work devices, including the work device used alone. Moreover, even if you do this, if it becomes necessary to reassemble a work device that was previously used with one work device into a line that includes multiple work devices,
It is difficult to do anything about it.

Problems to be Solved by the Invention The present invention solves the problem in that, as described above, when a single working device is used, the conveying device, which must protrude a certain amount to both the left and right sides of the working device, can move the working device. When multiple units are lined up to form a line, they become a nuisance, making the line unnecessarily long, and in order to avoid this, it is necessary to manufacture work equipment equipped with four types of conveyance devices. However, this was done in order to solve the problem of not being able to deal with the situation when it becomes necessary to convert a single working device into a production line.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a main side frame of a conveying device having a length approximately equal to the width of the main body of the working device, and a main side frame of the conveying device having a length approximately equal to the width of the main body of the working device. The main side frame is provided with a positioning device that stops and positions the printed circuit board at an intermediate position in the longitudinal direction of the main side frame. , auxiliary side frames are removably connected to both ends of the main side frame in a state that protrudes laterally from both ends of the working device main body, and one of the auxiliary side frames has a drive rotating body driven by a drive device, Further, a driven rotating body is provided on the other auxiliary side frame, and an endless belt is wound around both of these rotating bodies, so that the printed circuit board can be conveyed along both the auxiliary side frames and the main side frame by the endless belt. At the same time, when either of the auxiliary side frames is removed, the end of the main side frame on the side from which the auxiliary side frame has been removed is directly connected to the main side frame of another adjacent work device, and a series of conveyor The gist of this is that it has been made possible to do so.

Effects of the Invention" 2), one type of working device having only the main side frame of the conveying device is manufactured, and separately, an auxiliary side frame equipped with a driving rotary body and a driven rotary body are manufactured. All that is required is to manufacture an auxiliary side frame with a That is,
When using one work device, it is sufficient to connect the auxiliary side frames to both ends of the main side frame, and when multiple work devices are lined up in a line, the main side frames of adjacent conveyance devices can be connected to each other. It is sufficient to connect the auxiliary side frames each having a driving rotary body and the auxiliary side frame having a driven rotary body at both left and right ends of the main side frame thus connected.

In addition, if it becomes necessary to add an additional device to a working device that was previously used, remove either the left or right auxiliary side frame and attach the conveyor device of the additional device to the end of the removed side. A line can be easily formed by connecting the main side frames and connecting the removed auxiliary side frame to the other end of the main side frame.

On the other hand, a drive pulley 66 as a drive rotary body is attached near the tip of the auxiliary side frame 520. As is clear from FIG. 5, the drive pulleys 66 are also disposed close to the inner surface of the auxiliary side frame 52, and are connected to each other by a single long rotating shaft 68 so that they cannot rotate relative to each other. That is, in FIG. 5, the lower drive pulley IJ66 is fixed to the rotating shaft 68, and the pin 69 fixed to the upper driving pulley 66 fits into the groove 70 formed along the axial direction of the rotating shaft 68. This prevents relative rotation. A sprocket 71 is fixed to one end of this rotating shaft 68, and a chain 76 is wound around this sprocket 71 and a sprocket 74 fixed to the output shaft of a motor 72, whereby the drive boob IJ66 is rotationally driven by the motor 72. It is now possible to do so.

are screwed together.

A handle 92 is fixed to one end of a screw member 86 provided on the side of the auxiliary side frame 52, and a sprocket 94 is fixed to the other end. Since a chain 96 is wrapped between one end of the screw shaft 86 and a fixed sprocket 94, when the handle 92 is turned, the two screw shafts 86
rotate at the same time, changing the distance between the two side frames 44. Incidentally, sprockets 98 having a smaller diameter than the sprockets 94 are rotatably provided on both sides of the sprocket 94 fixed to the screw shaft 86 on the side of the main side frame 48. The hook is not used when it is only passed, and when multiple mounting devices are connected as described in detail later, the chain 96 is attached to the upper side of the sprocket 98 and the sprocket 94.

The stopper device 100 is connected to the main side frame 4 by a bracket 107.
The piston rod 109 of the air cylinder 10 engages with the front edge of the printed circuit board 84 when it is extended, and allows the printed circuit board 84 to pass when it is contracted. It is like that. The bra 5 kerato 107 is further provided with a photoelectric detector 110 that detects when the printed circuit board 84 comes into contact with the piston rod 109 serving as a stopper.

The lifter 102 includes a lift plate 112 that is raised and lowered by a lift cylinder 111. The lift plate 112 has a guide rod 1 extending vertically downward.

A support jig 118 that supports the printed circuit board 84 from below is removably attached to the lift plate 112. This support jig 118 includes a support plate 120 and a column 122 attached to the upper surface of the support plate 120. Post 122
Although only one is representatively shown in FIGS. 3 and 5, in reality, a large number of them are provided, and the support plate 1 is fixed with a bolt 128 at the leg portion 126 in which the elongated hole 124 is formed.
It is fixed at 20. Conveyance 6 of this embodiment Since many electronic components having lead wires are already mounted on the back side of the printed circuit board 84 conveyed by the device 40, the printed circuit board 84 can be curved without interfering with these electronic components. In order to support without
The fixing position of the support column 122 can be adjusted so that the upper end of the support column 22 hits an appropriate location on the printed circuit board 84.

Moreover, since the support jig 118 is removable from the lift plate 112 as described above, the position of the support column 122 can be adjusted in advance outside the machine, and the printed circuit board on which the chip is to be mounted can be adjusted. Changeover work can be done quickly when changes occur. In addition, the support plate 12
By preparing support jigs 118 with different sizes of 0 in multiple stages, it is possible to select and use the support jigs 118 suitable for the size of the printed circuit board 84.

The support jig 118 is accurately positioned by a plurality of positioning pins 130 erected on the upper surface of the lift plate 112 and fixed by bolts 132, so even if it is repeatedly attached and detached, The contact position with respect to the printed circuit board 84 will not shift.

The positioning pin 104 is fixed to a bracket 107 that supports the stopper device 100. As is clear from FIGS. 3 and 5, the positioning pin 104 is fixed downward in a vertical position to the upwardly extending protrusion of the endless belt 78 of the bracket I-1, 07.
Since the conical guide portion is formed at the lower end, when the printed circuit board 84 is lifted by the lifter 102,
It can be fitted into a positioning hole formed at a corner of the printed circuit board 84 to accurately position it. As is clear from FIGS. 3 and 5, a presser foot 134 is fixed to a main side frame 48 different from the main side frame 48 provided with the positioning pin 104.

The holding plate 134 is fixed to the main side frame 48 in a state extending above the endless belt 78, and when the printed circuit board 84 is lifted by the lifter 102, the protrusion of the bracket 107 to which the positioning pin 104 is fixed is attached. It plays a role of holding down and fixing the printed circuit board 84 from above in cooperation with 8.

The pulling down device 106 includes a rod 138 supported by a bracket 136 fixed to the outer surface of the main side frame 48 so as to be vertically movable. This rod 138
An engagement pin 140 is attached to the upper end that extends almost horizontally and whose tip reaches a position above the endless belt 78, and when the rod 138 descends, it engages with the edge of the printed circuit board 84 from above. It is made to play the role of an engaging part that pulls down this. A spring 142 is disposed between the engagement pin 140 and the bracket 136,
Although the rod 138 is biased in the upward direction, the rod 13
8, a pin 14 is erected at the middle part in the longitudinal direction of the pin 14.
4 engages with the upper end of an elongated part 146 formed on the bracket 136 to be elongated in the vertical direction, thereby preventing the rod 138 from rising above a certain limit. Note that this pin 144 also plays the role of preventing rotation of the rod 138. The lower end of the rod 138 is bent at a right angle so that it can engage with the lower surface of the lift plate 112, and when the lift plate 112 descends, it engages with this and descends against the biasing force of the spring 142. It is now possible to do so.

As is clear from FIG. 3, the bracket 107 that holds the stopper device 100 and the positioning pin 104 and the bracket 136 that holds the pull-down device 106 are
Since it is fixed to the main side frame 48 by a bolt 150 inserted through an elongated part 148 formed along the longitudinal direction of the main side frame 48, the fixing position can be adjusted along this elongated part 148. can. It is also possible to adjust the spacing between similar brackets 107 and 136 shown in FIG. 2, making it possible to position an extremely small printed circuit board 84' as shown by the dashed line in FIG. It is also possible to do this.

The transport device 40 of this embodiment is provided with a buffer station where the printed circuit board 84 is temporarily placed on standby.

That is, as shown in FIG. 4, an air cylinder 108 is attached to a bracket 107 that holds the positioning pin 104 on the printed circuit board entry side, and a stopper device 100 similar to the stopper device 100 described above is configured. The printed circuit board 84 transported by the transport device 40 is stopped at a position a certain distance upstream of the chip mounting station.

A lift cylinder 154 is disposed further upstream of the stopper device 100.

A bracket 156 is fixed to the inner surface of the main side frame 48, and an elongated hole 158 extending in a direction perpendicular to the main side frame 48 is formed in the horizontally extending portion of the bracket 156. An arm member 16 formed with
2 is fixed by a bolt 164, and the arm member 1
A lift cylinder 154 is attached to one end of 62 in a vertical position. The arm member 162 can be fixed in various positions relative to the bracket 156, and when fixed in the position shown by the two-dot chain line in FIG. The printed circuit board 84 is brought into a horizontal position by touching the approximately central part of the large printed circuit board 84, lifting it, and pressing it against the four holding plates 166 attached to the main side frame 48 and the auxiliary side frame 51O. can be held. Furthermore, if the state shown by the solid line in FIG. 4 is moved further to the right by a certain distance, the small printed circuit board 84' shown by the dashed line in FIG. It can be held in a horizontal position in cooperation with two presser plates 166 fixed to the.

The chip mounting operation using the chip mounting apparatus configured as described above is performed as follows. First, a printed circuit board is supplied to the left end side of the conveyance device 40 as shown in FIGS. 2 and 4 by a printed circuit board supply device (not shown).

When the supplied printed circuit board 84 is conveyed to the endless belt 78 and reaches the buffer station, the stopper device lo is reached.

The photoelectric detector 110 detects this, and the lift cylinder 154 is activated based on the detection signal to lift the printed circuit board 84 from the endless belt 78. In this state, the printed circuit board 84 is Wait until the chip installation process is completed.

At the same time that the chip mounting operation for the previous printed circuit board is completed and it is carried out from the chip mounting station by the endless belt 78, the bar.

The printed circuit board 84 that has been waiting at the fast station is carried into the chip mounting station. That is, the piston rod of the lift cylinder 154 is contracted and the printed circuit board 84 is lowered onto the endless belt 78, and at the same time the piston rod of the air cylinder 108 is also contracted to allow the printed circuit board 84 to move forward.

Immediately before the printed circuit board 84 conveyed by the endless belt 78 reaches the chip mounting station, the piston rod 109 of the air cylinder 108 of the chip mounting station is extended so that it can engage with the front edge of the printed circuit board 84. The printed circuit board 84 that has been transported is stopped at approximately a predetermined position by the stopper device 100. The photoelectric detector 110 detects this, and based on the detection signal, the lift cylinder 111 is operated to raise the lift plate 112 and the support jig 118, and the tip of the support column 122 comes into contact with the back surface of the printed circuit board 84. . If the support jig 118 is further raised from this state, the printed circuit board 84 will be lifted off the endless belt 78.
Accurate positioning is achieved by fitting the positioning piston 104 into positioning holes formed at the two corners of it.

At this time, since the rod 138 of the pull-down device 106 is raised by the spring 142, the engagement pin 140 does not prevent the printed circuit board 84 from rising, and the printed circuit board 84 is supported from below by the support jig 118 and from above. It is pressed and fixed by the holding plate 134 and the protrusion of the bracket 107.

In this state, appropriate tape feeding devices 14 are sequentially operated to supply chips, and the holder 16 is moved to receive the chips, convey them to a predetermined position on the printed circuit board 84, and mount them.

When the chip mounting operation on the printed circuit board 84 is completed, the lift plate 112 and the support jig 118 are lowered by the lift cylinder 111. The printed circuit board 84 normally descends along with this, but in the unlikely event that the positioning bin 104 is difficult to separate from the positioning hole and the printed circuit board 84 does not descend, the printed circuit board 84 is attached to the rod 13B that is lowered by the lift plate 112. The engagement pin 140 engages the edge of the printed circuit board 84 and forces it down. Therefore, the printed circuit board 84 is again supported by the endless belt 78 and is carried out from the chip mounting station.
It is passed to the printed circuit board receiving device from the right end side of the conveying device 40.

By repeating the above operations, chips are automatically mounted on a large number of printed circuit boards 84. However, if the size of the printed circuit board 84 to which chips are to be mounted changes, the stopper device 100 and the positioning pins 104 are removed. While adjusting the positions of the bracket 107 that holds the bracket 107, the bracket 136 that holds the pulling down device 106, the arm 5 member 162 that holds the lift cylinder 154, etc.,
Turn to adjust the distance between the two side frames 44.

Then, by replacing the support jig 118 with another support jig in which the position of the support column 122 has been adjusted in advance, the setup change work is completed. As described above, according to the apparatus of this embodiment, setup change work can be performed easily and quickly.

The case where one chip mounting device of this embodiment is used has been described above, but if it becomes necessary to use multiple chip mounting devices side by side, multiple chip mounting devices can be used as shown in Fig. 6. They can be installed close to each other. That is, chip mounting apparatuses each having only the main side frames 48 to which the auxiliary side frames 50 and 52 are not connected are arranged close to each other, and the main side frames 48 are directly connected to each other by the connecting member 54, and both left and right ends are connected to each other. By connecting the auxiliary side frames 50 and 52 to the main side frame 48 of the main side frame 48 using the connecting member 54, a series of side frames 168 can be formed which extend across a plurality of chip mounting devices and have both ends protruding to the side by a certain amount. You can get it. A chain 9 of an appropriate length is then attached to the sprocket 94 held on the auxiliary side frame 652 and the sprockets 94 and 98 held on the main side frame 48 of the plurality of chip mounting devices, respectively.
6, and also wrap an endless belt 78 of an appropriate length around the driven pulley 62 held on the auxiliary side frame 50 and the drive pulley 66 held on the auxiliary side frame 52. A conveying device 170 of a suitable length is completed.

As described above, in the present embodiment, one or more chip mounting devices can be installed close to each other, and the Ill feeding device W170 can be easily constructed with a length suitable for the device. In addition, if it becomes necessary to change the number of chip mounting devices in a line that has been configured, the connection between the main side frames 48 or between the main side frames 48 and the auxiliary side frames 50 or 52 can be changed using the connecting member 54. It can be easily unraveled by removal and a new line can be easily constructed. Moreover, no matter how long the conveying device 170 becomes, only one handle 92
By operating the main side frames 48 and the auxiliary side frames 50, 52, the intervals between them can be changed all at once.

Above, an embodiment in which the present invention is applied to a chip mounting device has been described in detail, but it is also possible to apply the present invention to a circuit inspection device for a printed circuit board after a chip has been mounted, and it is also possible to It is also possible to apply the present invention to a processing device that performs some processing on a substrate.

In addition, although not illustrated individually, the present invention can of course be practiced with various modifications and improvements made to each part of the apparatus.
