[Detailed description of the invention] [Industrial application field]

The present invention relates to a component mounting device, and more particularly to a component mounting device that grips a component with a chuck and moves the component to a predetermined position for mounting.

[Summary of the invention]

Three types of parts are chucked at the same time, and while the insertion head moves to the mounting position of the circuit board, the pitch between the three parts is adjusted by moving the chucks on both sides, thereby adjusting the pitch between the parts to the insertion pitch. Try to match the
Three types of components are inserted into a circuit board at the same time, and the leads that come out under the circuit board are clinched.
The present invention provides a radial component insertion machine that is inexpensive and highly productive. K. Prior Art) In order to mount electronic components on a circuit board, a chuck for inserting electronic components as disclosed in, for example, Japanese Unexamined Patent Publication No. 145893/1983 is used. Such a chuck grips the component and moves the chuck to a predetermined position to mount the electronic component on the circuit board. Such an automatic insertion machine usually has 40 to 80 stations, and inserts the parts one by one into the insertion program, cutting and clinching the leads protruding from the bottom surface of the board. The insertion tact time J of conventional parts insertion machines for high-mix, high-volume production is often around 0.5 seconds/piece. The main functions of such machines include detecting the presence or absence of a component chuck, detecting insertion errors, lead clinch mechanism, board bad mark detection, lead guide I1m, and automatic insertion error recovery. There are many things to prepare for. An inexpensive in-line type odd-shaped parts insertion machine is used as a parts insertion machine for production of small numbers of products and low labor. In terms of component quality, each head is made of one type, and the design is for in-line multiple heads. One or two points of the 10 types are inserted per station for lead clinch. The insertion takt time is slow at 3 to 4 seconds/piece, making it difficult to see an investment effect, and it is used for the purpose of saving manpower. Problems to be Solved by the Invention K] Conventional insertion machines for mass production of various products are octavalent, and are unsuitable for mounting hybrid ICs. Furthermore, it cannot be applied to parts such as small electrolytic capacitors where the lead pitch is 1.5 mm, and there is a drawback that zero insertion is not possible. Furthermore, the device has a large dimension and is not space efficient. The price per head will be lower for low-volume, low-volume production equipment, but when mounting chemical capacitors with three types of light-receiving elements, three sets are required, increasing the investment amount. do. Furthermore, since the takt time for insertion is slow, it is necessary to further increase the number of machines in order to increase production volume. Also, the lead pitch is 1.5. m
There is a problem in that 0 insertion cannot be performed for electronic components of m. The present invention has been made in view of these problems, and provides a component mounting device that is inexpensive as a whole and that is capable of mounting electronic components with high efficiency even when the lead pitch is small. The purpose is to provide the following. Means for Solving Problem K] The present invention provides an apparatus in which a component is gripped by a chuck and moved to a predetermined position for mounting, in which a chuck support is moved to the predetermined position by a moving means.

As shown in FIG. 6, the guide rail 18 extending in the lateral direction is divided at an intermediate position, and a board lock bin 28 is disposed at the divided position. A rotary table 29 is arranged below the position where the board lock bin 28 is provided, and the rotary table 29
An anvil 30 is provided on the lower side of 9 (see FIG. 7). Also, an air cylinder 3 is installed on the side of the rotary table 29.
1 is provided. Furthermore, an X-axis moving table 32 and a Y-axis moving table 33 are provided on the pedestal 10 so as to be perpendicular to each other. A trowel-shaped frame 36 is arranged on the pedestal 10 as shown in FIG. 7, and a guard motor 37 is mounted on the frame 36. A cam 39 is fixed to the output shaft 38 of the geared motor 37. This cam 39 is attached to a swing arm 40 shown in FIG.
It is in contact with a roller 41 attached to the tip of the roller. The arm 40 is rotatably supported around a fulcrum pin 42, and a cam follower 43 provided at the other end of the arm 40 is held by a slide rail 44. This slide rail 44 is guided by a guide rod 45 on the frame 36 so as to be movable in the vertical direction. As shown in FIG. 7, a pair of sliders 48 are slidably engaged on the slide rail 44. As shown in FIG. The slider 48 is connected to an insertion base 50 via a connecting rod 49. This insertion base 50 is connected to a Z-axis moving table 52 via a linear guide 51 shown in FIG.

is movably supported. And left and right chuck 5
7.58 are each connected to a lever 61 via a link 60. The upper end of the lever 61 is rotatably supported around a fulcrum pin 62, and the intermediate portion of the lever 61 is connected to a piston rod 64 of an air cylinder 63. Further, as shown in FIGS. 7 and 8, this device is equipped with a control panel 65 on the upper right side of the insertion base 50. In the above configuration, the rod 23 of the substrate loading block 22 is placed along the guide rail 18 of the substrate loader 19.
The substrate 20 is supplied by. The substrate 20 is moved to the center position of the loader 19 in FIG. 6 and is received by the rotary table 29 at this position. The rotary table 29 receiving the circuit board 20 includes an X-axis moving table 32 and a Y-axis moving table 3.
Moved by 3. Further, the circuit board 20 is moved in the rotational direction by the rotary table 29. This ensures that the components to be mounted with the chuck are placed in the correct position on the circuit board 20. Components to be mounted, e.g. electrolytic capacitor 68
is supplied by the tape magazine 11. Then, the tape containing the electrolytic capacitor 68 supplied from the magazine 11 moves along the tape guide plate 12, and when it reaches the lead wire cutter 13, the lead wire of the component 68 is cut at this position. In this position, the three parts 68 are gripped by three chucks 56, 57, and 58 in the positional relationship shown in FIG. At this time, the piston rod 64 of the air cylinder 63 shown in FIG. 1 has been pushed out, so that the left and right levers 61 are each in an open state. Therefore, left and right chucks 57.5
8 is in a state separated from the central chuck 56 as shown in FIG. In this state, the cam 39 is
When the pivot arm 40 shown in FIG. 8 rotates once, the swing arm 40 shown in FIG. Therefore, by such movement, the parts 68 on the lead wire cutter 13 of each tape guide plate 12 are moved three times.
The chucks 56, 57, and 58 grip each other as shown in FIG. 5, and while gripped, rise again and return to the original position. When the insertion base 5o supporting the three chucks 56, 57, 58 is raised, this base 50 will now move to the right in FIG. Move it onto the circuit board 20. Moreover, at this time, the air cylinder 63 shown in FIG. 1 retracts the piston rod 64, thereby causing the left and right chucks 57, 58 to move toward the center. This state is clearly shown in FIG. 2, where the left and right chucks 57 and 58, which are in the solid line position, move to a position where they are almost close to the center chuck 56. After the insertion base 50 has moved toward the mounting position and the pitches of the chucks 56, 57, and 58 have been adjusted in this way, the guard motor 37 is rotated again, and the cam 39 causes the swing arm 40 to swing. Do exercise. This movement causes the insertion base 50 to descend again via the slide rail 44 and the connecting rod 49. The electrolytic capacitors 68 supported by the three chucks 56, 57, and 58 provided on the insertion base 50 are then mounted on the circuit board 20. As described above, according to the electronic component mounting device according to this embodiment, the radial component 68 is cut to the required lead length,
The tape guide plate 12 is placed on standby at the position of the lead wire cutter 13, and chucked at the same time by chucks 56, 57, and 58. Since the chuck claws 56 to 58 stabilize the posture of the component 68 and do not cause the component 68 to fall, a spring chuck is used to achieve compactness. Note that the presence or absence of components is simultaneously detected using a high-precision switch. In addition, among the three chucks 56, 57, and 58, the left and right chucks 57, 58 are designed to slide, and when the insertion base 50 moves, they slide to the adjacent pitch of the three parts, thereby The parts 68 are inserted at the same time. In such an insertion operation, if an insertion error occurs, the set in which the insertion error occurred is detected and recovery is performed on the spot. Note that the component 68 with a lead pitch of 1.5 mm is not currently commercially available, but this insertion machine cuts the lead into 1.8 to 2 nm and inserts the fixed anvil with a chevron-shaped groove placed under the rotary table 29. At 30, you will be able to do a lead clinch. Further, the mounting direction of the component 68 is adjusted by setting the circuit board 20 to Oo or 90' using the rotary table 29. According to such a device, the amount of equipment investment becomes low. In addition, although it is inexpensive, three parts are inserted at the same time, so the insertion tact is faster. It is also a small electrolytic capacitor 68 with a lead pitch of 1.
．． Clinch insertion of 5mm parts becomes possible. Furthermore, since the chucks 56 to 58 fit within the external dimensions of the component 68, self-cleaning becomes possible even if the bodies of the components come into contact. Furthermore, although the lead pitch is narrow, bridging does not occur during automatic soldering because it does not clinch. In addition, since the lead length is cut short to 1.8 to 2 lengths by the lead wire cutter 13 before the parts are chucked, the probability of insertion is increased. [Effects of the Invention] As described above, the present invention provides A number of chucks on a chuck support base that is moved to a predetermined position by a moving means, and the pitch between the plurality of chucks can be adjusted by the pitch adjusting means. It is composed of Therefore, it is possible to efficiently mount components with a simple configuration, and in particular, it is possible to mount multiple components at the same time, so it is possible to provide an inexpensive component mounting device with a fast insertion tact. It becomes possible.
