Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for inspecting parts attached to an inspection workpiece and stamping a passing stamp on the inspection workpiece that has passed the inspection. The present invention relates to a passing stamp accommodating device.

(Prior Art) In recent years, automatic control of automotive air conditioners has progressed, and along with this, a large number of various parts such as sensors have come to be installed in the automotive air conditioners. Therefore, products in the manufacturing process of automotive air conditioners (hereinafter referred to as inspection work)
The inspection process for parts installed in the machine has become complicated.

FIG. 3 is a perspective view showing an inspection process for parts installed in a heater unit that constitutes a part of an air conditioner for an automobile.

As shown in the figure, various parts are attached to a heater unit 1 as an inspection workpiece, and wiring cords 2 are connected to these parts. An input terminal 4 of an inspection device 3 is connected to this wiring cord 2, so that the energization state of the wiring cord 2 and the components connected to the wiring cord 2 is inputted to the inspection device 3. If there is an abnormality in the energization state of the component, the inspection device 3 detects it and causes the warning lamp 5 to output an NG (reject) signal to notify the inspector of the abnormality in the inspection work 1. ing. In addition, if the energization state of the part is normal, an OK (pass) signal is output to the warning lamp 5,
It is designed to inform the inspector that the heater unit 1 as the inspection work is normal. The inspector confirms that the warning lamp 5 in the inspection device 3 is OK.
Only when a signal is output, a stamp indicating that the inspection has passed (hereinafter referred to as a pass stamp) is stamped on the heater unit 1.

(Problems to be Solved by the Invention) However, in this method of inspecting the parts of the inspection workpiece and stamping a passing stamp on the inspection workpiece that passed the inspection, due to the inspector's carelessness,
There was a risk that a passing stamp would be affixed to a failed inspection work. In addition, there is a risk of forgetting to put a passing stamp on a passed inspection work, and in that case, there is a risk that the inspection work will have to be inspected again because it will not be known whether the inspection work has been inspected or not. Ta.

The present invention was made in view of the above circumstances, and provides a pass stamp storage device that is used when inspecting parts of inspection workpieces and stamping pass stamps to prevent inspectors from being careless. The purpose is to provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for inspecting parts mounted on an inspection workpiece and stamping a passing stamp on the inspection workpiece that has passed the inspection. A passing stamp storage device for storing stamps includes an abnormality detection means for detecting an abnormality in an electric signal input from the component, and a stopper is driven to allow the passing stamp to be taken out only when the abnormality detection means does not detect an abnormality. a stopper driving means, a stamp position detecting means for detecting whether or not a passing stamp has been taken out from the device, and a counter for adding and displaying the number of times when the stamp position detecting means detects that a passing stamp has been taken out. It is characterized by having the following.

(Function) Using such a passing stamp storage device,
If the parts of the inspection work are inspected and a passing stamp is affixed to the inspection work that passes the inspection,
Since the pass stamp can be taken out only when the inspection passes, there is no chance of the inspector inadvertently stamping a pass stamp on a rejected product. In addition, since the number of inspection workpieces that have passed the inspection can be accurately grasped by the counter, by comparing the quantity calculated by this counter with the quantity of inspection workpieces that have actually been inspected, it is possible to avoid incorrect stamps of passed inspection. It is possible to know the quantity of inspection work that has been forgotten to stamp, and to discover carelessness.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is an overall perspective view showing a pass stamp accommodating device according to an embodiment of the present invention, and FIG. 2 is a flowchart showing its control mechanism. A code is attached.

As shown in FIG. 1, various parts are attached to a heater unit 1 as an inspection workpiece, and wiring cords 2 are connected to these parts. The wiring cord 2 is connected to an input terminal 4 of an inspection device 3 serving as an abnormality detection means for detecting an abnormality in the electrical signal inputted from the wiring cord 2.
Also, the energization state of the components connected to the wiring cord 2 is input to the inspection device 3.

On the other hand, the pass stamp 10 that is stamped on the inspection workpiece 1 that has passed the inspection includes a handle part 11 for gripping, a stamp part 12 on which a mark indicating passing is engraved, and a connection that connects the handle part 11 and the stamp part 12. Part 13
It consists of. This pass stamp 10 is stored in a storage box 16 in a pass stamp storage device 15 in an unused state. A stopper holding column 17 is provided upright on one side wall of the storage box 16.
The column 17 is provided with a cylinder 1 as a stopper driving means for driving the stopper 18 forward and backward in its axial direction.
9 is installed. The stopper 18 is moved by the column portion 17 due to the air pressure inside the cylinder 19 in a normal state.
It extends from the pass stamp 10 to the connecting portion 13 in the pass stamp 10, so that the pass stamp 10 cannot be taken out from the storage box 16. Said cylinder 1
9 is connected to a solenoid valve 21 via a tube 20;
A predetermined air pressure is introduced into the cylinder 19 by the action of the solenoid valve 21, and the stopper 18 is driven. Further, the electromagnetic valve 21 is connected to an output terminal 22 of the inspection device 3 as an abnormality detection means for detecting an abnormality in the electric signal inputted from the wiring cord 2. And this solenoid valve 21
Only when the inspection device 3 as the abnormality detection means determines that the energization state of the wiring cord of the component in the heater unit 1 as the inspection work is normal, the inspection device 3 receives an output signal from the output terminal 22 and detects the inside of the cylinder 19. A predetermined air pressure (negative pressure in this case) is introduced into the cylinder 19, and the stopper 18 is moved backward toward the cylinder 19 to release the stopper 18 from the pass stamp 10.

In addition, a storage box 1 in which the pass stamp 10 is stored.
A limit switch 23 is attached to the bottom of the stamp 6 as a stamp position detection means for detecting whether or not the acceptable stamp 10 has been taken out of the apparatus. This limit switch 23 has a counter 24.
is connected, and when the limit switch 23 detects that the pass stamp 10 has been taken out, the counter 24 calculates the number of times the pass stamp 10 has been taken out.

Next, the operation of such a pass stamp accommodating device 15 will be explained based on FIG. 2.

First, the wiring cord 2 in the heater unit 1 as the inspection workpiece is connected to the input terminal of the inspection device 3. Then, the inspection device 3 as an abnormality detection means
receives electrical signals from the parts of the inspection workpiece (step 30). Next, the inspection device 3 inspects whether or not the energization state of the parts of the inspection workpiece is normal based on the electric signal (step 31). If this inspection passes, an OK signal is displayed on the warning lamp 5 in the inspection device 3, and an electric signal is sent from the output terminal 22 to the solenoid valve 21, which applies negative pressure to the cylinder 19. The stopper 18 is moved backward in the cylinder direction, and the acceptance stamp 10 can be taken out from the storage box 16 (step 32). Next, the pass stamp 10 is taken out from the storage box 16, and the pass stamp 10 is used to stamp the heater unit 1 as the inspection workpiece to the effect that the inspection has passed. At this time, the limit switch 23 detects whether or not the pass stamp 10 has been taken out (step 33), and if the pass stamp 10 has been taken out, a signal is sent to the counter 24. When the signal is input to the counter 24, the counter 24 adds up the number of times and displays the number of times the pass stamp 10 has been taken out (step 34). Next, when the pass stamp 10 is returned to the storage box 16, the limit switch 23 detects it (step 35).
Sends a signal to the solenoid valve 21. Solenoid valve 2 that received the signal
1 sends a predetermined air pressure to the cylinder 19 to move the stopper 18 forward in the direction of the connecting portion 13, returning it to its original locked state and making it impossible to take out the pass stamp 10 (step 36).

Next, the inspection device 3 determines whether the wiring cord 2 in the heater unit 1 as the next inspection work is connected to the input terminal 4 (step 3).
7) If the inspection work is set, the process returns to step 30 and the above-described operations are repeated. Furthermore, if the next inspection work is not set, the process ends there.

In addition, when it is determined in step 31 whether or not the inspection passes, if the inspection fails,
An NG signal is output to the warning lamp 5, and the pass stamp 10 remains unable to be taken out. (Step 38).

Therefore, if such a pass stamp storage device is used to inspect parts of an inspection work, even if an attempt is made to affix a pass stamp to an inspection work that has failed the inspection, the pass stamp cannot be taken out, so the seal cannot be stamped. This prevents inspectors from being careless. In addition, the number of inspection workpieces that have passed the inspection can be accurately grasped by the number displayed on the counter 24, so by comparing the quantity displayed by this counter with the quantity of inspection workpieces that have actually been inspected, errors can be confirmed. It is possible to grasp the quantity of inspection work for which a passing stamp has been forgotten, and to discover carelessness.

(Effects of the Invention) As described above, according to the present invention, a passing stamp that accommodates a passing stamp when a part attached to an inspection workpiece is inspected and a passing stamp is stamped on an inspection workpiece that has passed the inspection. In the storage device, an abnormality detection means for detecting an abnormality in an electric signal inputted from the component; and a stopper driving means for driving a stopper to enable the acceptance stamp to be taken out only when the abnormality detection means does not detect an abnormality. The present invention includes a stamp position detection means for detecting whether or not the passing stamp has been taken out from the mounting, and a counter that adds up and displays the number of times when the stamp position detection means detects that the passing stamp has been taken out. If the pass stamp storage device is used when inspecting parts of an inspection work, the inspector who inspects the inspection work may inadvertently affix a pass stamp to an inspection work that has failed the inspection. This can be prevented. Further, even if the inspector mistakenly mixes an uninspected inspection work with an inspection work that has passed inspection, he or she can realize the carelessness later.
