Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a component joining apparatus that performs a brazing process using, for example, laser irradiation.

[Technical Background of the Invention and its Problems] Conventionally, parts joining devices have been developed for joining dot pins and armatures by brazing or other processing in, for example, print heads of dot printers. This component joining device includes a jig for attaching the components to be welded, and a laser irradiation device for brazing the components attached to the jig. After attaching the parts to the jig and supplying the brazing material, the operator sets the jig at the irradiation position of the laser irradiation device.

In contrast to such a manual device, a component joining device is being considered in which only the switch operation for attaching and detaching components to and from a jig is manual, and all other steps are automated. In this automated device, safety measures for the operator are an important issue. However, it is extremely difficult to satisfy both safety measures and simplification of operation.

[Object of the Invention] An object of the present invention is to provide a parts joining apparatus which can automatically carry out the joining process of parts with simple operations and which can improve the safety aspect for the operator.

[Summary of the Invention] The present invention includes a drive means for moving a base such as a table on which components are placed to a bonding processing section of a bonding processing means such as a laser irradiation device. The operation of the jig for placing the component on the base is controlled by the switch control means. The safety operation means control executes the safety operation during the operation period of the driving means or the joining processing means when the switch control means is in the OFF state. The operation of the safety operation means is configured to be canceled by a release means.

With this configuration, it is possible to reliably achieve safety for the operator who operates the switch control means.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a perspective view showing the configuration of a parts joining device according to an embodiment. As shown in FIG. 1, the parts welding apparatus includes a rotary table 10 that serves as a base on which parts to be welded (hereinafter referred to as workpieces) are placed, and a rotary table 10 that is arranged at predetermined intervals on the rotary table 10. For mounting the workpiece, use jig 11,
a workpiece take-out section 12 that takes out a workpiece from this jig 11;
A workpiece supply section 13 that supplies workpieces to the jig 11, a brazing material supply section 14 that supplies brazing material for joining, and a laser irradiation device 15 that performs joining processing (processing of the brazing material) of the workpieces attached to the jig 11. The brazing material is equipped with an air injection part 16 and a manual switch operation part 17 for blowing air out to the processed workpiece. The workpiece takeout section 12 includes a workpiece takeout hook switch (hereinafter referred to as takeout hook SW) 2 that controls the drive of the workpiece takeout cylinder 18, workpiece takeout completion lamp 19, and takeout cylinder 18.
It is equipped with 0. The work supply unit 13 includes a work supply cylinder 21 , a work supply completion lamp 22 , and a work supply hook switch (hereinafter referred to as supply hook SW) 23 that controls the drive of the supply cylinder 21 .

The brazing material supply section 14 includes a brazing material supply position setting cam motor 2
4. A brazing material supply cam starting point sensor 25 and a wax supply control section 26 are provided. The air injection section 16 includes an air blowing pipe 27 and an air blow solenoid section 28. The laser irradiation device 15 includes a laser irradiation port 29, and specifically has a configuration as shown in FIG. Further, the switch operation section 17 includes an operation panel as shown in FIG.

Furthermore, as shown in FIG. 1, the component matching device includes a sensor light emitting section 30 and a sensor light receiving section 31 that constitute a safety device. This safety device is activated when the component alignment device is in automatic mode and the take-out hook 5W20 and the supply hook 5W23 are turned off.

When the safety device detects the operator's arm or the like near the rotary table 10, the entire device is brought to an emergency stop and the emergency stop lamp of the switch operation section 17 is turned on.

The safety device is configured to be released when the select switch of the switch operation section 17 is switched to the manual side.

FIG. 2 is a front arrow view of FIG. 1. As shown in FIG. 2, the rotary table 10 is rotationally driven by a rotary motor 32, and each rotation is detected by a rotation detection limit switch 33.

In the parts aligning apparatus configured as described above, the operation of this embodiment will be described with reference to the flowchart of FIG. 5, especially in the automatic mode (AUTO). First, when power is supplied to the apparatus, it is assumed that the automatic mode is selected by the select switch of the switch operation section 17, as shown in step S2. When the operator confirms that the device is not in an emergency stop state, he performs the operations shown in steps 85 to 811. That is, the operator operates the take-out hook SW2O or the supply hook 5W23 shown in FIG. When the operator confirms that the lamp 19.22 indicating completion of workpiece removal or supply is lit, he turns off the hook 5W20 and the supply hook 5W23. As a result, the operations shown in steps 312 to 315 are executed, and the rotary table 10 starts rotating.

Thereafter, the series of brazing materials undergo sequential processing steps (steps 316-534). That is, the rotary table 10 stops every time it rotates once, and brazing material is supplied from the brazing material supply section 14 to the workpiece attached to the jig 11. The jig 11 supplied with the brazing material is set at the irradiation position of the laser irradiation bag @15. At this time, in the laser irradiation device 15, the row width guide cylinder 34 shown in FIG. 1 operates (step 528), and the row width guide 35 is set on the workpiece attached to the jig 11 (
step 529). As a result, the workpiece is brazed at a predetermined position. A laser beam is irradiated from the laser irradiation port 29 onto the workpiece on which the row width guide 35 is set (step 531). The brazed workpiece is moved to the air injection section 16 after the row width guide 35 is released. Then, the processing from step 319 will be performed again.

By the way, as shown in step 315, the rotary table 1
0 rotates and the brazing process is started, if an object or an operator's hand, etc. is detected near the rotary table 10 by the safety device consisting of the sensor light emitting section 30 and the sensor light receiving section 31 shown in FIG. do. As a result, as shown in steps 837 and 338, the rotation of the rotary table 10 is brought to an emergency stop, and the emergency stop lamp of the switch operation section 17 is turned on. In other words, a safe operation has been executed. In addition, in such automatic mode,
When the emergency stop switch 3B shown in FIG. 1 is manually turned on, the device is also brought to an emergency stop in the same manner as in the safety operation. After that, as shown in steps 339 to 841, the fault that caused the emergency stop of the device is removed, and the switch operating section 17 is removed.
Switch the select switch to the manual side. As a result, the emergency stop lamp goes out and the emergency stop state is released. Moreover, such an emergency stop operation will be executed if the processes shown in steps 825, 829, and 334 are incomplete.

In this way, the operator can use the extraction hook 3 W2O
, In the automatic mode in which only the supply hook 5W23 is operated, if a failure occurs during operation of the device, the system automatically enters an emergency stop state. That is, when the operator's hand or an obstacle approaches the vicinity of the rotary table 10 (i.e., the jig 11) while the apparatus is operating in the automatic mode, the safety device detects this.

Upon detection of this safety device, the parts joining device comes to an emergency stop and maintains the emergency stop state until it is released by a select switch or the like. The emergency stop state is canceled by switching the select switch of the switch operation section 17 to the manual side as described above. This is because safety measures are not as important when the device is in manual mode.
It can also function as a switch, and the effect of simplifying the configuration of the switch operation section 17 can also be obtained.

[Effects of the Invention] As described in detail above, according to the present invention, when an operator's hand or an obstacle approaches the vicinity of the parts while performing a joining process such as brazing parts in the automatic mode, the automatic is detected and the equipment is brought to an emergency stop. Therefore, in the automatic mode in which the C1 operation is simplified, safety processing for the operator etc. can be reliably realized.
