Abstract

PURPOSE:To smoothly carry out the pitch feed of parts, by providing a plurality of part feeders, drive devices for driving the former, a shifter head, etc. so that one of the part feeders drives the other one at a position out of the part absorbing position of the shifter head. CONSTITUTION:After a part 3a of a parts feeder 1a being absorbed to a nozzle 6, a shifter head 7 loads the part 3a onto a print board. When a part 3b on another parts feeder 1b is loaded, a drive device 10b feeds a parts feeder 1b by pitches a simultaneously with the final pitch feed of the part feeder 1a. In other words, the parts feeder 1b is pitch-fed simultaneously with the shifter head7 absorbing the part 3a on the parts feeder 1a. Therefore, if a plurality of drive means are provided to carry out pitch-feed from the time of initiation of motion to the time of absorption, it is possible to carry out the operation with a smooth motion in comparison with the arrangement of conventional part feeders.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a component mounting device.

2. Description of the Related Art In recent years, there has been remarkable progress in equipment for mounting electronic components onto printed circuit boards, and there has been a demand for faster mounting speeds.

Therefore, parts supply devices are also required to have a high supply speed. Conventionally, a component supply device is selected within the time the transfer head is moving, moves to the pick-up position of the transfer head, drives the component supply device by the drive device, performs pitch feeding, and the transfer head picks up the components. was used to attach parts to printed circuit boards.

Problems to be Solved by the Invention However, in the conventional configuration, the component feeding device moves to the suction position and then performs pitch feeding, so there is a limit to increasing the feeding speed. This caused problems such as electronic parts dancing and popping out. Therefore, the present invention attempts to protect the electronic components by performing pinch feed at a location other than the suction position.Means for Solving the ProblemsIn order to solve the above problems, the present invention The component supply device is configured to be driven by the driving means in a state where the component supply device is located outside the component suction position of the transfer head.

Effect: The above means allows the drive means to slowly drive the component supply device.

Example Examples of the present invention will be described below.

In FIG. 1, reference numeral 1 denotes a component supply device provided with a tape 2 on which components are stored, and a plurality of components supply devices are provided on a table 4 that moves on a guide rail 6 in a direction iA. The parts supply device 1 is provided with a push rod 11, and this push rod 11
Pitch feed (drive) is performed in the C direction by pressing . Reference numeral 1o denotes a pitch feeding drive device located below the push rod 11 and operated by a cam, and the push rod 14 of this drive device 10 is configured to push the push rod 11 in the D direction. Reference numeral 7 denotes a transfer head that picks up the components of the component supply device 1, moves in the E direction, and mounts them onto the printed circuit board 12;
Shutters 9 a and 8b are provided next to the transfer head 7 to prevent parts from falling out of other parts supply devices 1.
This is a drive device that drives a and 9b. Note that 13 is a guide rail for transporting the printed circuit board 12.

In the above configuration, as shown in FIG. 2, when the component 3ai of the component supply device 1a is to be suctioned to the nozzle 6 of the transfer head 7, the push rod 14 of the lower drive device 10a moves in the direction of the push rod 11'kD. The component supply device 1a is pitch-fed by raising the push rod 11, the components 3ai are supplied, the transfer head 7 is lowered in the E direction, and the nozzle 6 performs full suction.

The nozzle 6 that has picked up the component 3ai attaches the component 3a to the printed circuit board 12 by moving the transfer head 7 in the E direction.

When loading a plurality of parts 3a of the parts supply device 1a, the above-described operation is repeated. However, next time another component supply device 1b
When mounting the component 3b, at the same time as the last pitch feed of the component supply device 1a is carried out, the drive device 10b
Pitch feeding of the electronic component supply device 1b is performed. Then, when the table 4 moves in the direction A and the component supply device 1b is located at the suction position, the component 3b that has been pitch-fed in advance
The Q nozzle 6 attracts and transfers the material. At this time, as shown in FIG. 3, the displacement of the cam of the drive device IQa can be performed from the beginning of the cycle time, so that pitch feeding is performed smoothly to the suction position 15. In addition, the drive device 10b is smoothly driven to perform pitch feeding, regardless of the suction position 16, except for the moving time 17 of the table 4, up to the feeding completion position 22. The same applies to the component supply device 10C.

However, since the pitch feed is set a little steeper in the operation of the drive device 1ob than in the operation of the drive device 10a, the cylinders 8a and sb operate at the same time as the pinch feed of the component supply devices 10b and 1oc is performed. Shafter-9a
, 9biB direction to prevent the electronic component 3b from flying out.

In this way, the transfer head 7 is connected to the component 3a of the component supply device 1a.
At the time of suction, pitch feeding of the component supply device 1b is performed smoothly at the same time.

Effects of the Invention As described above, according to the present invention, by providing a plurality of drive means, when a component is picked up from the component supply device and pitch-fed, the drive device at the suction position can perform pitch-feeding from the start of operation to the suction time. The process is smoother than before, which reduces the chance of electronic parts popping out or dancing, allowing for stable supply. In addition, when picking up components from another component supply device, the other component supply device is driven by a separate drive device at the same time as the drive device at the suction position, and this drive also performs pitch feeding, excluding the movement time of the component feed device. It can be performed with smooth movements. In addition, by providing the shutter at the top, pitch feeding can be performed more stably, so that it is possible to cope with higher speed component mounting.
