Abstract

PROBLEM TO BE SOLVED: To judge the quality of a product automatically and inspect accurately by installing a transfer means for transferring a jet nozzle intermittently and a liquid supply means for supplying a liquid to the jet nozzle stopped on a specific position to the jet nozzle attachably/detachably and installing a perceive means of a jet liquid. SOLUTION: An intermittently rotating table 2 is installed on the upper surface of a base stand and a fix means 3 for fixing a jet nozzle main body 101 is installed in an upper surface 4 direction. An elevating plate 9 is installed in the lower side of the table 2. Liquid supply members 19, 20, 21 for sending out the liquid through respective brackets 16, 17, 16 are fixed on the cylinder rods of air cylinders 13, 14, 15 fixed on the elevating plate 9. A detection board 26 is fixed on the upper side of the elevating plate 9 and a target hole 28 is formed on the detection board 26. It is judged to a good part when the liquid belched out from the jet nozzle main body 101 passes the target hole 28, runs against a cup 29, swings the cup 29 and a swing plate 30 and is detected by a detection device 32.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet nozzle inspection device for a window washer mounted to clean a windshield of an automobile or the like.

[0002]

2. Description of the Related Art First, a jet nozzle of a window washer will be described with reference to FIG. Reference numeral 101 denotes a jet nozzle body, and a fixing portion 10 to which a tube communicating with a liquid tank is fixed below the jet nozzle body 101.
2 is formed. In addition, the jet nozzle body 101
A through hole 103 through which the window washer liquid is delivered is formed inside the fixed portion 102. Further, one end of the through hole 103 (the front end of the jet nozzle body 101) is a large diameter portion 104, and the large diameter portion 104 is formed.
A substantially spherical positioning member 105 for positioning the liquid ejection direction is press-fitted into the. Of course, the positioning member 1
A through hole 106 is also formed in 05.

Next, an apparatus for inspecting whether or not the positioning member 105 is press-fitted into an accurate position will be described with reference to FIG. Reference numeral 107 is an inspection board made of transparent resin, and targets 108 and 109 are drawn on the inspection board 107. A mounting table (not shown) for fixing the jet nozzle body 101 in front of the inspection board 107.
And so on.

Next, the inspection method will be described. First, the jet nozzle main bodies 101 are fixed to the mounting table one by one by a human hand, and then a tube for delivering a liquid is press-fitted into the fixed portion 102 of the jet nozzle main body 101. Here, the pressurized liquid is poured into the tube. The liquid is delivered by the positioning member 10.
It will be discharged from 5. If the discharged liquid hits the targets 108 and 109 of the inspection board 107, it is determined as a non-defective product. On the contrary, if the liquid does not hit either one, it is determined as a defective product. After the inspection is completed, the tube is removed, the jet nozzle main body 101 is removed from the mounting table, and a new jet nozzle main body is fixed to the mounting table again.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and a transfer means for sequentially and intermittently transferring jet nozzles of a window washer at a predetermined interval, and a liquid jet to a jet nozzle stopped at a specific position. The liquid supply means for supplying is detachably arranged on the jet nozzle, and the sensing means for sensing the liquid ejected from the jet nozzle is arranged at a specific front position.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a transfer means for sequentially and intermittently transferring jet nozzles of a window washer and a liquid supply means for supplying a liquid to a jet nozzle stopped at a specific position are detachably attached to the jet nozzle. It is characterized in that a sensing means for sensing the liquid ejected from the jet nozzle is disposed at a specific front position, and as a result, the quality of the product can be automatically judged and the productivity is accurately and accurately inspected. You can

[0008]

The jet nozzle sent from the transfer device is placed on the rotary table which is rotated intermittently by the robot device, the liquid is supplied at a predetermined position, the liquid is jetted from the nozzle toward the target, and the sensor is detected when it hits the target correctly. The product is detected as a non-defective product, and if it does not hit the target, it is determined as a defective product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 is a base, and an intermittently rotating table 2 is attached to the upper surface of the base 1. Further, the jet nozzle body 101 is provided on the upper surface 4 direction of the table 2.
The fixing means 3 for fixing is attached. On the other hand, in the four directions near the outer periphery of the table 2 on the upper surface of the base 1, the jet nozzle main body 101 is sequentially separated from the storage device 4 and the transport device 4 and placed one by one on the fixing means 3. The robot device 5 to be placed, the inspection means 6 for inspecting the jet nozzle body 101, the discharging device 7 for discharging the liquid remaining in the inspected jet nozzle body 101 by air blow or the like, and the inspected jet nozzle body 101. A transfer device 8 is arranged to take out from the fixing means 3 and transfer it to another place.

The inspection means 6, which is a feature of the present invention, will be described in detail below with reference to FIGS. 3 and 4. An elevating plate 9 is disposed near the outer periphery of the table 2 and below the table 2, and the elevating plate 9 is moved up and down by an air cylinder 10. More specifically, the air cylinder 10 is fixed to the base 1, and the lift plate 9 is fixed to a cylinder rod 11 of the air cylinder 10 via a connecting rod 12. Then, three air cylinders 13, 14, 15 are fixed to the lift plate 9, and the cylinder rods of the respective air cylinders 13, 14, 15 are connected to the liquid cylinders via the brackets 16, 17, 18, respectively. The liquid supply members 19, 20 and 21 for delivering the liquid are fixed. In addition,
The respective liquid supply members 19, 20, 21 are leaf springs 22, 2
It is also fixed to the bracket via 3, 24. This is because the liquid can be reliably supplied and delivered to the jet nozzle by floating the liquid supply member. 25
Is a container that catches the liquid should it leak.

Next, the detection board 26 for detecting the liquid discharged from the jet nozzle body 101 will be described.
The detection board 26 is fixed above the lifting plate 9. The detection board 26 has target holes 27, 28.
A rocking plate 30 to which a cup 29 that receives the liquid discharged from the jet nozzle body 101 is fixed is attached via a hinge 31 to the rear of the target holes 27 and 28 (the rear surface of the detection board 26). Has been. Further, on the rear surface of the detection board 26, a detection device 32 such as a proximity switch or a micro switch for detecting the swing of the cup 29.
Has been fixed.

That is, if the liquid ejected from the jet nozzle body 101 passes through the target holes 27, 28 and hits the cup 29, the cup 29 and the oscillating plate 30 are oscillated, and if the detection device 32 detects the liquid, then it is judged as a good product. To be done. vice versa,
If either one does not hit, it is judged as a defective product. If it does not hit, the discharge pressure is weak,
There is a case where the press-fitting position of the positioning member 105 is not accurate. In this embodiment, the intermittent rotation type device has been described, but a linear device may be used.

[0013]

According to the present invention, there is provided a transfer means for sequentially and intermittently transferring jet nozzles of a window washer at predetermined intervals.
Since the liquid supply means for supplying the liquid to the jet nozzle stopped at the specific position is detachably arranged on the jet nozzle, and the sensing means for detecting the liquid ejected from the jet nozzle is arranged at the front specific position, The quality can be automatically judged, the productivity is good, and the inspection can be performed accurately.
