Abstract

PURPOSE: To realize the total inspection of the absence or presence of un-cut parts of the base plate of an electrical product, in which a metal. plate is insert- molded and which is obtained by cutting a molded article, by a method wherein the vertically moving shaft of a base, to which a plurality of detecting pins are fixed at positions corresponding to the cut parts of the molded article, is raised when uncut parts are present and the raised position of the shaft is detected. CONSTITUTION: When a molded article is moved to an inspection device 11, the vertically moving shaft M of an air cylinder 8 is actuated and lowered, resulting in lowering the inspection device 11 and also detecting pins 19. When the cutting operation of electrode parts is performed correctly with a pressing machine, the detecting pins 19 pass the cut parts, resulting in being judged as a conforming article. However, it even one part is uncut, the lowering of the detecting pin 19 is checked, resulting relatively in bringing the detecting pin 1.9 at raised state. The action results a sliding member 15 also in bringing at raised state and also bringing a detecting plate 22 at raised state. Thus, a gap develops between the detecting plate 22 and a sensor 21 so as to be detected by the sensor 21 and judged as a non-conforming article.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection device for making a hole or the like in a member by press working or the like and inspecting whether or not the hole is accurately opened.

[0002]

2. Description of the Related Art Generally, visual inspection is performed as a method for making a hole or the like in a member by pressing or the like and inspecting whether the hole is accurately opened or not.

[0003]

However, in the above-mentioned prior art, it is difficult to inspect all parts due to poor productivity, and for example, one part is inspected for 20 parts by sampling inspection or the like. Or, there was no choice but to adopt a method of inspecting one part for 50 parts. However, in these days when safety is important, 1
When the number of defectives came out, after all, it was necessary to inspect all (all parts).

In addition, even if the inspection is performed visually, an inspection error (so-called oversight) may occur due to fatigue or the like, and it cannot be said to be a reliable inspection method. Here, for example,
In the case where the above-mentioned parts are the base of an electric product or the like, if a defective product is overlooked, a short circuit occurs and a serious accident such as a fire occurs.

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above problems, and a molded product obtained by cutting a predetermined position of a metal plate of a molded product obtained by insert-molding a metal plate into a resin portion by a press machine. The lift shaft of the base, which has a plurality of detection pins fixed to the position corresponding to the section, is movably arranged vertically through the elastic member, and when there is an uncut part, the lift shaft is lifted and the lift position is detected. It is characterized in that a detecting device is installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. 1 and 2. FIG.
FIG. 1 is a diagram showing the configuration of the entire system, and 1 is a so-called insert molding machine that fixes a metal plate or the like to a molded product simultaneously with molding. The molding machine 1 molds a molded product 2 as shown in FIG. 3 is a resin part, and 4, 5
Is the inserted metal plate portion. By the way, the molded product 2 is an electrode substrate used for a television, a radio, a rotary switch mechanism, or the like. The molding machine 1
A conveyor device 6 that conveys the insert-molded molded product 2 is disposed in the vicinity of. And the molding machine 1
A take-out robot 7 that takes out the molded product 2 from the molding machine 1 and places it on the conveyor device 6 in the vicinity of the conveyor device 6.
Is arranged. Reference numeral 8 is a hand member that holds the molded product 2, and reference numeral 9 is a moving mechanism such as a ball screw mechanism that moves the hand member 8 in the X-axis direction.

A device located in the middle of the conveyor device 6 is a press machine for cutting and partitioning the metal plate parts 4, 5 of the molded product 2 into set electrode parts 4a-4f, 5a-5f. It is 10. The molded product 2 cut and divided by the press machine 10 is shown in FIG. Here, it is conceivable to insert-mold the previously cut electrode portions 4a to 4f and 5a to 5f, but not only the mechanism for holding the electrode portion such as a die becomes more complicated, but also the die The number of steps (the number of times) for inserting the electrode portion into is increased, and the production cost and the productivity are deteriorated.

Reference numeral 11 is an inspection apparatus of the present invention, which is an apparatus for inspecting whether or not the portion cut by the press machine 10 is cut accurately. More specifically, a hollow guide cylinder 13 is fixed to a lifting shaft H such as an air cylinder S via a bracket 12. A sliding member 15 having a base 14 fixed to the lower end is slidably attached to the guide cylinder 13. The sliding member 1
A fixed block 16 is fixed to the upper end of the guide 5 to prevent the fixed block 16 from falling off the guide cylinder 13. An elastic member 17 such as a coil spring is stretched between the bracket 12 and the base 14 so that the base 14 is constantly urged downward.

A plurality of detection pins 19 are fixed to the base 14 in such a manner that a neck portion 19a is sandwiched by a plate 18. The base 14 and the plate 18 are fixed by bolts 20. Further, the detection pin 19 is fixed to the electrode parts 4a to 4f and 5a to 5f at positions corresponding to the cutting device.

On the other hand, a sensor (detection device) 21 such as a photoelectric tube or a proximity switch is fixed to the bracket 12 located above the base 14, and a detection plate (dog) fixed to the fixed block 16 is provided. It is designed to operate only when it is separated from 22.

Next, the operation will be described. The molded product 2 insert-molded by the molding machine 1 is placed on the conveyor device 6 by the take-out robot 7. This conveyor device 6
Thus, the molded product 2 is moved to the press 10. Then, the pressing machine 10 causes the plurality of electrode portions 4a-4a to
f, 5a to 5f are formed. Next, the molded product 2 is moved to the inspection device 11. Here, the lifting shaft H of the air cylinder S is operated and lowered, and the inspection device 11 is lowered. As the inspection device 11 descends, the inspection pin 19 also descends. Here, if the cutting operation of the electrode portion by the press machine 10 is accurately performed, the detection pin 19 passes through the cut portion and is judged as a good product. However, if the detection pin 19 is not cut even at one place, the detection pin 19 is prevented from descending, so that the detection pin 19 relatively rises. By this operation, the sliding member 15 is also raised, and
The detection plate 22 is also raised. Here, the detection plate 22
A gap is generated between the sensor and the sensor 21. And
The sensor 21 detects this gap and determines that the product is defective.

Further, in this embodiment, the elastic member 1 is
The resilience of 7 is set to be somewhat strong, and the electrode part which is about to be cut can be cut by the detection pin. Further, since the position of the detection pin 19 can be easily changed by loosening the bolt 20, it is possible to respond quickly and smoothly even if the molded product changes.

[0013]

According to the present invention, a plurality of detection pins are fixed at a position corresponding to a cut portion of a molded product obtained by cutting a predetermined position of a metal plate of a molded product in which a metal plate is insert-molded with a resin portion. Since the lifting shaft of the table is arranged to be movable up and down through the elastic member and the lifting shaft is lifted when there is an uncut portion, and a detection device for detecting the lifting position is attached, 100% inspection is performed accurately. It is possible to improve productivity as well.
