DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic component supply device, and particularly to speeding up component supply.

2. Description of the Related Art Electronic component supply devices supply electronic components to devices that mount electronic components onto objects such as printed circuit boards. There are various electronic component supply devices, and an appropriate device is used depending on the type of electronic component. For example, as described in Japanese Patent Application Laid-open No. 145057/1984, there is a device that holds a large number of electronic components along the length of a tape and feeds the electronic components by feeding the tape at a constant pitch. . This device can quickly supply a large number of electronic components, but although it is suitable for supplying relatively small electronic components, it is not suitable for supplying large flat package type electronic components. Not suitable. This is because it is not easy to hold flat package type electronic components with tape. Therefore, in order to supply flat package electronic components, etc., the electronic components are stored in each of a plurality of trays, and the trays are arranged on one plane of a table, and the table is moved to select the desired tray. is sequentially positioned at the component supply position, and a device for supplying electronic components and a plurality of magazines each supporting a component supply tray are easily housed in large numbers vertically, and the desired magazine is protruded horizontally, and A device is used that moves the electronic component to a component supply position and supplies the electronic component.

Problems to be Solved by the Invention However, when a plurality of component supply trays are arranged on a table, a large space is required to install the table, and the number of component supply trays that can be placed is limited by the area of the table. However, there is a problem in that it is not possible to sufficiently increase the number and types of electronic components that can be supplied. Also, when arranging multiple magazines one above the other, it is possible to increase the number of magazines in a small amount of space.
Although various types of electronic components can be supplied, it is necessary to take the magazine in and out of the rack each time one electronic component is supplied, and there is a problem in that it takes time to supply the components.

The invention described in claim 1 has been made with the object of providing an electronic component supply device that can quickly position a desired magazine at a component supply position among a plurality of magazines arranged vertically. It is something that

The invention set forth in claim 2 can solve the problem of the invention set forth in claim 1, and simultaneously performs the positioning of a desired magazine to the component supply position and the evacuation of the magazine positioned at the component supply position. The object of this invention is to provide an electronic component supply device that is capable of providing electronic components and has a simple structure.

Means for Solving the Problems In order to solve the above problems, the invention of claim 1 provides (a) a component supply containing electronic components disposed vertically in multiple stages and in close proximity to or in contact with each other; A plurality of magazines each supporting a tray, (b) a low-speed moving device that moves the plurality of magazines simultaneously in the vertical direction, and (c) a low-speed moving device that moves one of the plurality of magazines in the middle of the vertical movement range. (d) move each magazine at a higher speed than the low-speed moving device for a certain distance above the parts supply position; and a high-speed moving device that forms a wider gap between the magazine and the other magazines than between the other magazines.

The invention of claim 2 also provides (a) a plurality of magazines disposed vertically in multiple stages in close proximity to or in contact with each other and each supporting component supply trays in which electronic components are accommodated; A camshaft having a cylindrical shape extending in the direction and having a spiral cam groove on its outer peripheral surface with a small lead angle at the upper and lower parts and a large lead angle at the middle part, and (c) a rotational drive for rotating the camshaft. (d) a cam follower attached to each of the magazines and engaged with the cam groove, and (e) one of the plurality of magazines between the lower part of the cam groove where the lead angle is small and the intermediate part. and a positioning device that positions the component supply position near the boundary with the portion with a large lead angle.

In the invention according to claim 2, the portion of the cam groove of the camshaft with a small lead angle, the rotary drive device, and the cam follower function as a low-speed moving device, and the portion of the cam groove of the camshaft with a large lead angle, the rotary drive device, and the cam follower function as a low-speed moving device. functions as a high-speed moving device.

Functions and Effects In the electronic component supply device according to the first aspect, one of the magazines is positioned at the component supply position by moving the plurality of magazines in the vertical direction. Since a wide gap is formed between the magazine positioned at this component supply position and the magazine immediately above it, electronic components can be taken out from the component supply tray by an electronic component supply device or the like through the gap.

According to the electronic component supply device of claim 1, since the magazines that accommodate component supply trays containing electronic components are arranged in multiple stages above and below, a large number and types of electronic components can be supplied in a small space. In addition, by moving the magazine vertically, you can position the desired magazine at the component supply position, so when you move the magazine in and out of the rack and move it vertically to supply electronic components. In comparison, electronic components can be supplied quickly. Since multiple magazines are moved vertically at the same time, albeit at a slow speed, the time required for the movement is short, and the wide gap formed above the parts supply position is a certain distance above the parts supply position. Since the wide gap is formed by moving the magazine at high speed, the wide gap can be formed in a short time. The formed component supply condition can be created in a short time, and electronic components can be supplied quickly.

In the electronic component supply device according to the second aspect, when the camshaft is rotated, the magazine is moved in the vertical direction by engagement between the cam follower and the cam groove. When it is engaged with a small part, it moves at low speed, and when it is engaged with a part with a large lead angle, it moves at high speed, so that a wide gap is formed above the component supply position.

As described above, according to the electronic component supply device of claim 2, it is possible to quickly supply a large number and types of electronic components, and the movement of the magazine and the formation of a gap above the component supply position can be performed at the same time. Therefore, the parts supply condition can be created in a shorter time, and the parts can be supplied more quickly. Additionally, cam grooves with different lead angles are formed on the top and bottom of a single camshaft, allowing the magazine to be moved at low or high speeds by rotation of the camshaft. The configuration of the device is simpler than when the devices are provided separately, and can be manufactured at low cost.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 2 is a diagram illustrating the appearance of an electronic component supply device that is an embodiment of the present invention. In the figure, 10 is a base, and a plurality of casters 12 are attached to this base 10 to make it movable. On the base 10, as shown in FIGS. 1 and 4, a substrate 14 fixed to the base 10, a substrate 14
A column 20 with a fixed top plate 18 is provided at the upper end of the column 16, and a column 20 is provided at the upper end of the column 16. Rotatably supported. A bevel gear 24 is attached to the end of the camshaft 22 that protrudes downward from the base plate 14, and is meshed with a bevel gear 28 fixed to the output shaft of a servo motor 26. The rotation of the servo motor 26 moves the camshaft 22 up and down. rotated about an axis extending in the direction.
The bevel gears 24, 28, the servo motor 26, etc. constitute a rotational drive device.

A pair of guide rods 30 are fixed to the base plate 14 and the top plate 18 in parallel with the camshaft 22.
10 magazine support members 32 are slidably fitted in the vertical direction with a certain gap therebetween.
As shown in FIG. 4, the magazine support member 32 includes an arm portion 34 that extends horizontally from the fitting portion with the camshaft 22, and a magazine support base 36 is attached to the arm portion 34 in a direction that extends forward. It is fixed in a cantilevered manner. As shown in FIG. 5, U-shaped guide rails 42 and 44 are provided on the opposing inner surfaces of both side frames 38 and 40 extending in the left-right direction of the magazine support stand 36, with their open sides facing each other. The magazine 46 is inserted into and pulled out from the magazine support base 36 while being guided by these guide rails 42 and 44.

The magazine 46 is shaped like a shallow container that opens upward, and as is clear from FIG. A pair of handles 49 are provided, and protrusions 52 and 54 are provided on the outer surfaces of a pair of side walls 50 and 51 parallel to the longitudinal direction, respectively.
are provided, and the guide rails 42, 44
is slidably fitted to. The magazine 46 supports a component supply tray 56 containing electronic components, and has a depth capable of accommodating ten component supply trays 56 stacked one above the other. In addition,
In this example, the printed circuit board (not shown)
It is assumed that each magazine 46, which is loaded with ten or less types of electronic components and supported by ten magazine support stands 36, accommodates a component supply tray 56 that accommodates one type of electronic component.

The component supply tray 56 is positioned within the magazine 46 in the width direction and the length direction. As shown in FIG. 4, a positioning plate 60 that extends in the width direction of the magazine 46 is fitted into the magazine 46 so as to be slidable in the longitudinal direction of the magazine 46, and is formed on the inner surface of the positioning plate 60. A rectangular positioning member 64 and an L-shaped positioning member 66 are slidably fitted into a pair of guide rails 62 (see FIG. 5) extending in the width direction of the component supply tray 56. Positioning in the longitudinal direction is performed by the inner surface of the member 64, the inner surface of the arm portion extending in the width direction of the positioning member 66, and the side wall 48 of the magazine 46.
The inner surface of the other arm portion of the magazine 46 and the side wall 5 of the magazine 46
Positioning in the width direction is performed by 0 and 0. The positioning plate 60 has two thumbscrews 68 and the side wall 50,
The magazine 46 can be fixed at any position in the longitudinal direction by elongated holes (not shown) formed in each of the positioning members 6 and 51.
4 and 66 can be fixed at any position in the width direction of the magazine 46 by thumbscrews 70 and 72 and elongated holes 47 (see FIG. 5) formed in the positioning plate 60, respectively. Therefore, by changing the positions at which the positioning plate 60 and the positioning members 64 and 66 are fixed, it is possible to position the component supply tray 56 of a desired size within the magazine 46.

Camshaft 22 of the magazine support member 32
A pin 76 as a cam follower is rotatably attached to the part to be fitted into the camshaft 22 and protrudes from the inner peripheral surface of the fitting hole into which the camshaft 22 is fitted. It is engaged with a cam groove 78 formed on the surface. The cam groove 78 is formed in a spiral shape, and each of the ten magazine support members 32 is engaged with the cam groove 78 at the pin 76, so that when the camshaft 22 is rotated, a predetermined gap is formed between the top and bottom of each other. They can be moved up and down at the same time while separated. The magazine support member 32 is raised when the camshaft 22 is rotated in the forward direction, and lowered when the camshaft 22 is rotated in the reverse direction.

To take out the electronic components from the component supply tray 56, the lowest magazine support member 32 among the 10 magazine support members 32 is located at the lowest end of the camshaft 22, and the 10 magazine support members 32 are placed in a small position. They are housed in the topmost magazine support member 32 in a state where they are close to each other with a gap between them.
The electronic component extraction device 80 (see FIG. 1) performs the extraction at the height where the topmost component supply tray 56 among the ten component supply trays 56 is located. This position is the component take-out position, and the magazine 46 is positioned such that the uppermost component supply tray 56 is located at the component take-out position, no matter how many component supply trays 56 it accommodates. Magazine 4 at this time
The position 6 is the component supply position, and this position changes depending on the number of component supply trays 56.
The electronic component extraction device 80 is equipped with a suction head 82 that is movable in two mutually orthogonal directions in a horizontal plane, and after taking out the electronic component from the component supply tray 56, it is moved to a position where it is evacuated from above the component supply tray 56 as shown in the figure. Place electronic components on a mounting table that does not have a built-in mounting table, or attach them directly to a printed circuit board.

The cam groove 78 of the camshaft 22 allows the thickness (vertical dimension) of the magazine support member 32 to be adjusted between the thickness (vertical dimension) and the adjacent magazine support member 32 by three rotations of the camshaft 22 in the portion below the component supply position. It is formed with a pitch of 16 mm so that it can be moved by 48 mm, which is equal to the sum of the gaps. Further, above the component supply position, in order to avoid interference between the electronic component takeout device 80 and the magazine support member 32 located above the magazine support member 32 positioned at the component supply position, the electronic component takeout device 80 is inserted. A gap is required to allow this. This gap is significantly larger than the distance between adjacent magazine support members 32, and therefore, the lead angle of the portion of the cam groove 78 a certain distance above the component supply position is larger than the lead angle of the portion below the component supply position. is,
The cam groove 78 is formed so that it can be moved by 357 mm by three rotations of the camshaft 22. Specifically, 357 points upward from the parts supply position of the cam groove 78
In the part up to the position separated by mm, the lead angle gradually increases as it moves upward away from the component supply position, reaches a maximum at the center position, and then gradually decreases until it reaches the part below the component supply position at the upper end position. It is designed to return to the same lead angle. In this embodiment, the camshaft 22 is rotated three times in one second, but for 0.25 seconds at the start and end of rotation, the magazine support member 32 is engaged with a portion with a relatively small lead angle and moved. A cam groove is formed so as to engage and move a portion with a relatively large lead angle during the intermediate 0.5 seconds.

As a result, the second and subsequent ones from the top of the plurality of magazine support members 32 shown by solid lines in FIG. When the magazine support member 32 is stopped at the position, the magazine support member 32 directly above it is moved from the component supply position to the electronic component mounting device 8, as shown by the dashed line in FIG.
It is moved to an avoidance position separated by a gap necessary to allow the intrusion of 0. Furthermore, the lead angle of the portion of the cam groove 78 above the avoidance position is
It is said to be the same as the part below the parts supply position.

In other words, when the camshaft 22 is rotated three times in the forward or reverse direction, the magazine support member 32 located below the component supply position and the magazine support member 32 located above the avoidance position simultaneously support one magazine at low speed. At the same time, the magazine support member 32 that was in the parts supply position is moved to the avoidance position, or the magazine support member 32 that was in the avoidance position is raised or lowered to the parts supply position at high speed, A gap is formed between the magazine support members 32 in both positions to allow the electronic component mounting device 80 to enter. Note that the portion of the camshaft 22 above the avoidance position has a length that allows nine magazine support members 32 to engage with each other.

The magazine support member 32 moved as described above is positioned at the component supply position by a sensor 84 shown in FIG. 4. This sensor 84
includes a light emitting device 88 fixed to the tip of a bracket 86 extending from the support column 16, and a light emitting device 88 fixed to the front part of the substrate 14 as shown in FIGS. 2 and 3, and located below the component supply position. It consists of a light receiver 92 fixed to a side plate 90 that covers the magazine support member 32 of. The light emitter 88 and the light receiver 92 are opposed to each other at a distance greater than the width of the magazine support member 32 in the front-rear direction of the electronic component supply device.
0, the side walls 50 and 51 of the magazine 46 are each provided with a notch that allows the passage of light emitted from a light emitter 88, so that the sensor 84 can detect the upper end of the component supply tray 56. In this embodiment, electronic components are supplied by raising the magazine support member 32, and during the raising, the light reception of the light receiver 92 is obstructed by the uppermost component supply tray 56 housed in the magazine 46. As a result, the rotation of the camshaft 22 is stopped, the component supply tray 56 is positioned at the component take-out position, and the magazine 46 is positioned at the component supply position. The sensor 84 constitutes a positioning device.

Note that when the electronic components in the component supply tray 56 run out, the tray 56 is transferred to the electronic component mounting device 80.
In such a case, the ejecting of the component supply tray 56 brings the light receiver 92 into a state where it receives light, so the servo motor 26 is started and the next component is ejected. The magazine support member 32 is moved until the component supply tray 56 is located at the component removal position. Since the upper and lower parts of the cam groove 78 between the electronic component supply position and the avoidance position each have a small lead angle, even when the second and subsequent component supply trays 56 from the top are positioned at the component removal position, The pin 76 engages with the portion of the cam groove 78 where the lead angle is small, and is accurately positioned at the electronic component supply position. Furthermore, since the magazine support member 32 is moved with substantially constant acceleration and deceleration, the impact and noise generated during the movement can be reduced.

The support column 16 includes a zero point and negative overtravel sensor 94 that detects the magazine support member 32 located at the lowest end of the camshaft 22, an avoidance confirmation sensor 96 that detects the magazine support member 32 located at the avoidance position, and a sensor 96 that detects the magazine support member 32 located at the lowest end of the camshaft 22. A plus-over sensor 98 located at the top end is provided. By detecting the magazine support members 32 by the zero point and negative overtravel sensor 94, it is detected that the ten magazine support members 32 are positioned below the component supply position, and the start of supply of electronic components is permitted. be done. Further, by detection by the avoidance confirmation sensor 96, it is confirmed that a gap is formed between the component supply position and the avoidance position to allow the entry of the electronic component extraction device 80, and extraction of the electronic component is started. Furthermore, plus over sensor 9
8, it is detected that the magazine 46 positioned at the component supply position is the last one, and the camshaft 22 is rotated in a direction to lower the magazine support member 32.

As shown in FIG. 3, this electronic component supply device further includes a magazine 4 that is pulled out from the magazine support member 32 when replenishing or replacing electronic components.
A magazine rack 100 for supporting 6 is provided. The magazine rack 100 includes a portion of the side plate 90 adjacent to the portion covering the magazine support member 32, and a side plate 104 attached to a support post 102 at a rear position separated from the portion by a distance wider than the width of the magazine 46. Contains. Side plate 9

10 pairs of guide rails 108 that can be fitted with 2 and 54
are attached at a pitch equal to the pitch between the magazine support members 32 in the vertical direction. The uppermost guide rail 108 is positioned corresponding to the component supply position where the uppermost component supply tray 56 is located at the component takeout position, and the magazine 46 has 10 pairs of guide rails 52 and 54. The magazine is pulled out to the magazine rack 100 in a position where it can fit into any one of the rails 108.

The top of the magazine rack 100 is the shutter 110.
It is becoming covered by Shutter 11
0 is guided by guide rails 112 and 114 fixed to side plates 90 and 104, respectively, and is moved between above magazine rack 100 and above magazine 46 positioned at the parts supply position.
The shutter 110 is always in a state where it covers the top of the magazine rack 100, but when the magazine is pulled out, it is moved to a position where it covers the top of the magazine 46.
This prevents the hand of a worker who pulls out the magazine 46 from hitting the parts ejecting device 80. Shyatsuta 100
The movement of the magazine to the above two positions is detected by the dog 115 operating the switches 116 and 118, respectively, and the camshaft 22 is rotated until the shutter 110 is returned to the position above the magazine rack 100. An interlock is taken to prevent this from happening.

Note that the opening on the right side of the magazine rack 100 is covered by a door 120 attached so as to be openable and closable, and the magazine support member 3
Magazine rack 100 out of the space in which 2 moves.
The upper part is also covered by a pivotable door 122 mounted at right angles to the side plate 90.

In the electronic component supply apparatus configured as described above, all ten magazine support members 32 are positioned below the component supply position before the supply of electronic components is started. In this state, the electronic component ejecting device 80 takes out electronic components from the component supply tray 56 of the magazine 46 supported by the topmost magazine support member 32 and retreats, and then the camshaft 2
2 is rotated, the top magazine support member 32 is moved to the avoidance position, and the second magazine support member 32 is moved to the parts supply position and positioned.

The ten magazines 46 are sequentially positioned at the component supply position and electronic components are taken out. When the removal of electronic components from the magazine support member 32 that supports the lowest one of the magazines 46 that actually accommodates the component supply tray 56 is completed, the camshaft 22 is rotated to the left. is,
All the magazine support members 32 are returned to a position below the component supply position, and are ready for supply of electronic components to the next printed circuit board.
