Description

DETAILED DESCRIPTION OF THE INVENTION [111] The present invention relates to a stick cassette in a component mounting device.

11"U (For example, when attaching many types of parts, such as electronic parts, to printed circuit boards, etc., it is often done by hand, which is especially inefficient on production lines with many working tools.
If it is done manually, there will be large variations in parts installation accuracy, etc.
There was an inconvenience that many defective products were produced due to incorrect installation or forgetting to install.

In order to compensate for the drawbacks of such manual work, a component mounting device that automatically controls components has recently been developed and used. A component mounting device basically includes a component supply means that sequentially supplies components, and a chuck that grips the components supplied by the component supply means, moves them in a predetermined direction, and attaches them to a work object (for example, a board). and a positioning drive mechanism that positions and drives the chuck at a component mounting position or the like. More specifically, the component supply means includes a stick cassette as a component source that stores a plurality of longitudinal sticks each holding a plurality of components in a stacked manner, and a component supply path. The chuck has a guide means for guiding the parts flowing out in free fall from the stick to the part gripping position by the chuck.

By the way, as described above, the parts of the plurality of sticks stacked in the stick cassette are sequentially discharged from the sticks at the lowest level.

The stick whose components have been completely discharged is discharged from the stick cassette, and the next stick is lowered and positioned at the component discharge position. In stick cassettes that have already been developed, a replacement line groove for ejecting and replacing the sticks is provided on the outside of the stick cassette, and for this reason, one stick cassette occupies a large space, making many stick cassettes narrow. It was not possible to store the parts within the space, and it was not possible to improve the parts supply efficiency that much.

11 The present invention has been made in view of the above-mentioned points, and its purpose is to provide a stick cassette that can be stored in large numbers in a narrow space and thus contributes to improving parts supply efficiency. It is.

A substrate moving mechanism 30 shown in the figure moves the pushed out substrate 5 onto the movable rail mechanism 23 on the table 17. Then, the servo motor 21 and the servo motor 25
is rotated, and the board is moved in the X-Y direction and conveyed directly below an attachment device 228 (shown in Figure 3) for attaching test terminals 235 (eg, shown in Figure 46) to the board.

At the same time as the substrate 5 is positioned directly below the mounting device, the groove 238 is pulled in the wye shown in FIG. I can move. Thereafter, the piston 245 and therefore the drive rod 246 shown in FIG. 42 are actuated, and the pawl member 243 grips the test terminal 235. When the claw member 243 grips the test terminal, the wire 2 described above
36 is loosened, and the head portion 233 returns to a position perpendicular to the main surface of the substrate 5. Here, table 1
It is confirmed that the movement of the substrate 7 is completed, that is, the positioning of the substrate 5 is completed. If this is not completed, the electromagnetic clutch 186 is not engaged and waits. When the positioning of the board 5 is completed, the wire 241 shown in FIG. 39 is pulled, and the test terminal 235 is inserted into the round hole (not shown) formed in the board 5.

The insertion of the test terminal 235 into the test terminal 235 is completed.

Next, the above-mentioned control device again drives the table 17 and the movable rail mechanism 23 (see FIG. 5, etc.) to start moving the substrate 5 directly below the desired chuck 117.

Then, the control device selects the chuck and engages the electromagnetic clutch 155 corresponding to the selected chuck. Next, the electromagnetic clutch 186 (shown in Figure 33) corresponding to the chuck is engaged.At this time, the shaft 17
8 is rotating, and as a result, FIGS. 34 and 35
Seven disc members 207a to 207g shown in the figure rotate. First, the pulse motor 169 rotates by a desired amount, and therefore the bracket 114 rotates and the selected chuck 117 is rotated so that the swingable direction of the chuck is backward, that is, in the direction of the component guide member 100. be given When the chuck 117 is rotated by a predetermined angle, the engagement state of the electromagnetic clutch 186 described above is released, and thereafter the electromagnetic clutch 155, the disc member 174 shown in FIGS. 31 and 32, and the pair)
The rotation angle of the chuck 117 is accurately corrected by the four sensors 175 and 176.

Here, correction of the rotation angle of the chuck 117 will be described in detail. Note that the photosensor 176 is used to accurately determine the rotational angular position of the chuck 117, and the C1 photosensor 175 detects whether the chuck is shifted clockwise or counterclockwise from its normal position. It is for.

The above-mentioned control device 280 (shown in FIG. 47) first checks whether the round hole 174b is aligned with the optical axis of the photosensor 176, that is, whether the photosensor 176 is in the on state. If the photosensor 176 is in the on state, the rotation angle of the chuck 117 is not corrected. Teeth for rotating and tightening the chuck 117] Belt 1
If the chuck 117 is shifted clockwise or counterclockwise in FIG. 32 by, for example, three pulses of the pulse motor 169 due to backlash between the toothed belt wheel 153 and the This direction is confirmed by the sensor 175 and the elongated hole 174a. If the photo sensor 175 is deviated clockwise, the photo sensor 175 is in the off state, and if it is deviated counterclockwise, the photo sensor 175 is in the off state.
The A sensor 176 is turned on. The control device thereby confirms the deviation in the rotational direction. Once the direction of the rotational deviation is confirmed, the pulse motor 9169 is rotated one pulse at a time in the direction that corrects the deviation, and this continues until the photosensor 176 is turned on.

When the rotation of the chuck 117 toward the component guide member 100 is completed, the electromagnetic clutch 186 is re-engaged, and the disk members 207a to 207g shown in FIGS. 34 and 35 are rotated again. As a result, as shown in FIG. 26, the chuck 117 is moved backward once around the bottle 118, and the chuck 117 is moved backward once (28th exit)
The claw member 128 of the chuck shown in FIG.
reach a position where you can grasp it. In addition, this chuck 117
The swinging is performed, for example, by pulling the outer casing wire 122 shown in FIG. 28+b+. Further, at this time, the claw member 128 is in the open state, 1, that is, in the non-gripping position. Next, the outer casing wire 125, also shown in FIG. 28(b), is loosened, the slider 124 is projected toward the electronic component 53 by the biasing force of the coil spring 126, and the claw portion 44128 reaches the electronic component gripping position. Further, the outer casing wire 133 for gripping the electronic component is pulled, and the electronic component 53 is gripped by the claw members 128. After that, the outer casing wire 125 is pulled and the slider 124 is moved to the frame 1.
At this position, the wire 145 is pulled and the claw member 139 grips, or positions, the wire 145 in a direction perpendicular to the gripping direction by the claw member 128. Also, the outer casing wire 122 is loosened and the chuck 11
7 returns to the position shown by the solid line in FIG.

Next, the pulse motor 169 rotates the desired amount, thus rotating the bracket 114 and causing the chuck 117 to rotate. Note that at this time, the anvil 221 shown in FIG.
rotation is also performed at the same time.

Next, the outer casing white t7145 is loosened,
The gripping state of electronic component 53 by claw member 139 is released. Thereafter, the engagement state of the electromagnetic clutch 186 is temporarily released, and accurate rotation angle correction of the chuck is performed by the electromagnetic clarifier f-155, the disc member 174, and the photo-insulators 175 and 176. At the same time, it is confirmed that the table 17 has been moved to the desired position. If the movement has not been completed, wait for the movement to be completed.

Then, the lifting operation of the anvil 221 shown in FIG. 36 is performed. At the same time, the outer casing wire 125
is loosened and the slider 124 protrudes in the direction approaching the board 5, and the terminal 53a of the electronic component 53 is fitted into the terminal hole (not shown) of the board 5, as shown in the 36th entry). After this, as shown in FIG. 48, the anvil 221
The terminal 53a of the electronic component 53 is clinched.

Next, the outer casing wire 133 is loosened, and the gripping state of the electronic component 53 by the claw members 128 is released.
The electronic component is attached to the substrate 5.

Thereafter, the anvil 221 is lowered, the electromagnetic clutch 186 is disengaged, and the rotation of the disk members 207a to 207g shown in FIG. 35 and the like is stopped.

However, at this time, each of the rotating disk members is stopped at its original position by the rightmost disk member 207a among the respective rotating disk members.

Thereafter, the above operation is repeated for each electronic component.

The board 5 with all the electronic components attached thereto is transported, for example, to the vicinity of the downstream fixed rail mechanism 12 shown in FIG. It is stored in the magazine 7.

Thereafter, the above operation is repeated for each board, and as a result, the elevator I structure 8.9 shown in FIG. .

Next, ejection and replacement of the sticks 54 stacked and stored in the stick cassette 44, which is a parts source, shown in FIG. 14, for example, will be explained.

When all of the electronic components 53 flow out of the stick at the bottom of the stacked plurality of sticks 54 and the stick becomes empty, the above-mentioned control device detects this using a predetermined detection means, and the control device shown in FIGS. 17 and 18 Slider 8 shown in the figure
4 is moved to a position corresponding to the stick cassette 44 containing the stick. After this, each of the air cylinder mechanisms 90 to 92 shown in FIG. 18, for example, is activated. As a result, the shutter 73 shown in FIG.
is opened, and at the same time, the stick 54 is discharged and replaced as shown in FIG. 49 (J or small) and FIG. 50 (ω or 52).

For correction of the rotation angle of the chuck 117 described above, a long hole 1 is provided in the disk member 174 (shown in FIGS. 31 and 32).
For example, a hole 174G (as shown in Figure 32) is provided as a single shape-changing portion without providing a large number of holes such as the round hole 74a and the round hole 174b.
It is also possible to set the rotation angle ?ili positive in this case.

First, the control device 280 (+1ffi Kei)
74, therefore, the Cf ptsu 117 is connected to the photosensor 176 or photosensor 175 by the pulse motor 169.
Rotate counterclockwise at high speed until the hole 174c aligns with the optical axis of the lens. For example, when the hole 17/IC matches the optical axis of the photosensor 176 and the photosensor turns on, the disc member 174 is stopped. However, as soon as the photo sensor 176 turned on, the pulse motor 1
Even if the chuck 69 is stopped, the stopping position of the chuck 117 will deviate from the normal rotation angle position by several pulses due to operational delays and inertia of the driving force transmission system. Therefore, the pulse motor 169 is rotated one pulse at a time in a direction to correct the deviation, and this rotation is continued until the photosensor 176 is turned on again. Further, when the hole 174c coincides with the optical axis of the photosensor 175 due to the above-described high-speed rotation in the counterclockwise direction, the control device 280 rotates the disc member 174 clockwise at a predetermined angle, that is, the distance between the photosensors 175 and 176. Rotate by an angle that is several pulses larger than the angle. Thereafter, the above-described procedure is repeated to correct the rotation angle.

When the second support means moves from the support release position to the support position U, the first support means moves from the support position to the support release position, and when the first support means returns to the support position, the second support means moves from the support position to the support position U. The support means is adapted to move into a support release position.

In this way, the exchange mechanism for discharging and exchanging sticks is built into the stick cassette body.
It becomes possible to make the entire stick cassette compact, and many stick cassettes can be arranged side by side in a narrow space, improving parts supply efficiency.

Further, in the stick cassette according to the present invention, the first support means includes a pair of gripping lever members (59) that closely grip the vicinity of the component outlet of the lowermost stick to position the component outlet; When the second support means moves from the stick support position to the support release position, the distance between the stick gripping surfaces of the gripping lever member is slightly larger than the thickness 1) of the stick (54). Therefore, the component outlet of the lowest stick is exactly aligned with the component inlet of the component supply path that is to follow the component outlet. This eliminates the stagnation of components that would occur if the component outlet and component inlet are even slightly misaligned, and the component supply efficiency is further improved.
