Abstract

PURPOSE:To provide a machine capable of easily mounting a new electronic device requiring no strict management control for loading without crushing solder using a conventional stroke characteristic even when an electronic device is mounted so far as being approximate. CONSTITUTION:In an electronic device mounting machine repeating suction of an electronic device 2 at a feeder by a nozzle and transfering it to a desired position of a substrate 1 followed by mounting the electronic device on the substrate with release of suction and returning, a compression spring 13e is mounted between a Z-axis table 4 and a suction nozzle part 13d. When a nozzle is driven by a servomotor, the compression spring is extended so that a lead of the electronic device comes in contact with solder of a printed substrate and only the guide part further goes down and the nozzle suction part stops at the spot where the spring force is balanced with solder elasticity so that the further decending guide part does not press the compression spring. Accordingly, inspite of an existing warp of the printed substrate, plenty of stroke characteristics are not required to be provided.

In FIG. 4, the distance H between the solder 1a and the lead 2a depends on the warp of the printed board 1, the coating amount of the solder 1a, the bending of the lead 2a, and the size of the electronic component 2. fluctuate. In the case of mass production, the error can be suppressed to a constant width by increasing the coating accuracy of the solder 1a and the processing accuracy of the bending of the lead 2a.
Since the size of the electronic component 2 is known in advance, the servo motor 4 may be driven so as to match the size. However, the warp of the printed circuit board 1 changes for each substrate.

Therefore, normally, the servo motor 4 is driven at a rate larger than the descending amount determined by the size of the electronic component 2.
Therefore, as shown in FIG. 5, the solder 1a and the lead 2a are
Since the nozzle 3 is lowered by the servo motor 4 even after the contact with, the suction nozzle portion 3d slides on the guide portion 3b while compressing the compression spring 3e.

Although the compression spring 3e absorbs the warp of the printed circuit board 1, the compression spring 3e cannot be used so much. That is, if the compression spring 3e is pushed too much, the solder 1a may be crushed instead of being crushed in balance with the elasticity of the solder 1a. Further, the descending speed of the nozzle 3 when the solder 1a and the lead 2a contact each other is also a cause of crushing the solder 1a. Therefore, it is necessary to strictly manage and control the lowering of the nozzle 3, that is, the stroke.

Even if a pressure sensor is installed and the extent to which the nozzle 3 is lowered by the servo motor 4 is controlled and the solder pressing force is controlled, the control device matches the size of each electronic component adsorbed by the nozzle. It is necessary to prepare a plurality of stroke characteristics, the electronic components to be mounted have been changed, and if the size is unprecedented, it is necessary to prepare a new stroke characteristic.

In the electronic component mounting machine according to the present invention, since one end of the compression spring is located at the fixed portion of the Z-axis table,
When the nozzle is driven by the servo motor, the compression spring expands, and when the lead of the electronic component comes into contact with the solder of the printed circuit board, only the guide part further descends, and the spring force and solder When the elasticity is balanced, the nozzle suction part stops and the compression spring is not pressed even if the guide part is further lowered. Therefore, even if the printed circuit board is warped,
It is not necessary to prepare many stroke characteristics for driving the nozzle. Furthermore, if the size of the electronic component to be handled does not change significantly, it is possible to handle it with the stroke characteristics up to now.

In FIG. 1, 13 is a nozzle, and the guide portion 13b is fixed to the arm 7. The suction nozzle portion 13d is installed in the guide portion 13b, and the flange 13f is engaged with the engaging portion 13g at the lower end of the guide portion 13b. The suction nozzle portion 13d is arranged concentrically with the guide portion 13b and can slide on each other. Fixed part 14 of Z-axis table 4

When the elastic force of the solder 1a and the spring force of the compression spring 13e are balanced, the guide portion 13b separates from the suction nozzle portion 13d, and the suction nozzle portion 13d is stopped, and only the guide portion 13b is the servo motor 5. To descend.
Meanwhile, even if the servo motor 5 continues to rotate, the compression spring 1
There is no further compression of 3e. That is, initially, the guide portion 13b seems to move the suction nozzle portion 13d toward the printed circuit board 1. However, when the lead 2a contacts the solder 1a, the guide portion 13b and the suction nozzle portion 13d are automatically separated. Resulting in. At the time of separation, since the spring 13e is loosened, the pressing force applied to the solder 1a at the time of contact is low, and even if the guide portion 13b is further moved, it is not strengthened, and the suction nozzle portion 13d is driven. It is not necessary to strictly control the stroke. Especially, even if the stroke speed is increased, the force of the lead 2a pushing the solder 1a is
Not as strong as the prior art. Therefore, the crushing of the solder is reduced, and the mounting can be performed with high accuracy with a simple structure.

b is the distance moved. The warp of the printed circuit board 1 is absorbed by this extra movement distance HT. Therefore, even if the stroke distance of the guide portion 13b is roughly set, the solder 1
The influence on a is small, and if it is reflected, there is an advantage that electronic components having different dimensions can be processed with one stroke characteristic, and it is not necessary to prepare many stroke characteristics. If the convex warp on the printed circuit board 1 is small, the moving distance HT is small.

1. An electronic component is sucked in a method of repeatedly picking up an electronic component by a nozzle at a feeder, transporting it to a desired position on a substrate, releasing the suction to mount the electronic component on the substrate, and returning the electronic component. The suction nozzle portion and the guide portion that houses the suction nozzle portion constitute a nozzle, and a compression spring that biases the suction nozzle portion toward the substrate is mounted between the Z-axis table and the suction nozzle portion. An electronic component mounting machine, characterized in that the guide portion is moved up and down by a driving means provided on a Z-axis table to mount the electronic component sucked by the suction nozzle portion on the substrate.

2. A Z-axis table in which the electronic components are picked up by a nozzle at a feeder, conveyed to a desired position on the substrate, and the electronic components are mounted on the substrate and returned by releasing the suction, which is repeated. Between the other end of the compression spring, one end of which is fixed to the cable, and the guide portion, which is moved in the direction of the substrate by the driving means provided in the Z-axis table, in the direction of the substrate rather than the guide portion. And a suction nozzle portion for the electronic component protruding to the substrate, and the compression spring is opened with the movement of the guide portion in the direction of the substrate to convey the electronic component sucked by the suction nozzle portion to a desired position on the substrate. A machine equipped with electronic components characterized by the above.
