Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically assembling and inspecting a cord reel built into an electrical product.

Conventionally, automatic winding cord reels for use built into electrical products have been manufactured by mechanization to some extent, but this requires manpower to install the cord reel into the equipment, and insulation resistance , dielectric strength,
Continuity tests and other tests used to use testers, which were both dangerous and very time-consuming.Also, with belt conveyor systems, the main purpose is only to transport, and processing requires separate equipment. As a result, it was difficult to position the cord reel relative to the equipment (equipment), and because the conveyor system was used, production did not meet the planned quantity or there were losses due to overproduction, so it was necessary to automate the production line. It was strongly requested.

The present invention was developed as a result of various studies in order to solve the above-mentioned drawbacks of conventional cord reel manufacturing, and the main part of the present invention is a pallet system instead of a belt conveyor. This enables automation, facilitates the positioning, loading and unloading of the cord reel, allows assembly and processing on the same line, and by keeping the production per hour constant, there is no need to worry about insufficient production quantity. We aim to improve reliability by eliminating losses such as overproduction, establishing various inspection processes through automation, and contributing to the establishment of quality assurance by making the inspection process a numerical test rather than a sensory test. The present invention also aims to provide a cord reel automatic assembly and inspection method and its device, which improve safety and are useful for improving the working environment through automation.

A sliding base 172 is installed in the center of 71 so as to be movable left and right. An air cylinder 173 is erected on the upper part of the sliding base 172, and the cylinder shaft 17
4 penetrates downward, and a suction jig mounting plate 175 is suspended from the lower end of the cylinder shaft 174, and three rows of vacuum parts 176, 1
76, 176 are attached to the suction jig mounting plate 175. On the other hand, between the support bases 169, 170 and the sliding base 172, there is a non-defective side moving cylinder 177.
As shown in FIG. 21, a cylinder 179 for determining good and defective products is installed on the sliding base 172, and the above-mentioned non-defective moving cylinder 177 and defective moving cylinder 178 are installed on the sliding base 172. 178 respective cylinder shafts 18
Locking tool 182,1 installed at the tip of 0,181
A cylinder shaft 184 of the good/defective product discrimination cylinder 179 is provided at 83 so that it can be inserted and locked. Furthermore, roller conveyors 186 and 187 are installed on both sides of the base 185 of the conveyor L, and a micro switch 189 for checking the workpiece is installed at the upper end of the support wall 188 of the roller conveyor 186 on the right side. installed on the transport pallet f
The pin 89a of the NG pin holder 89 is configured to hit the workpiece confirmation micro switch 189. 190 is a good product box, and 191 is a defective product box. The operating state of the device K having the above structure will now be described. The conveyance pallet f on which the cord reel a that has completed the assembly inspection process is fixed is the 20th pallet.
When the position shown in the figure is reached, the air cylinder 173 operates first, and together with the cylinder shaft 174, the suction jig mounting plate 175 and the vacuum parts 176, 176, 17
6 is lowered, and the vacuum parts 176, 176, 176 are attracted to the upper surface of the cord reel a. Next, the air cylinder 173 moves upward, and the cylinder shaft 174, the suction jig mounting plate 175, and the vacuum parts 176, 176, 176 rise, and the cord reel a is lifted. On the other hand, if the cord reel a is defective, the pin 89a of the NG pin holder 89 protrudes, so the pin 89a of the NG pin holder 89 protrudes.
9a is the micro switch 189 for checking the workpiece.
actuator, the workpiece confirmation micro switch 189 operates the good/defective product discrimination cylinder 179, the cylinder shaft 184 moves toward the defective product side, and the tip of the cylinder shaft 180 of the defective product side moving cylinder 178 is locked. The tool 182 is inserted and locked. Then, the defective product side moving cylinder 178 operates, and the cylinder shaft 180 comes to protrude to the left in the figure. Vacuum part 1 is transferred and when it comes directly above the defective product side roller conveyor 186.

In addition, when the code reel a is in good condition, the cylinder shaft 184 of the good product/defective product discrimination cylinder 179 is inserted into the good product side locking tool 183, and the good product side moving cylinder 17
7 is operated, and the cord reel a is carried to the non-defective side and stored in the non-defective product box 190. In the NG pin holder 89, when a defective state is detected in the inspection of each inspection device of the present invention, the pin 89a is raised and the code reel a in the defective state is transferred to the work confirmation micro switch 189 of the defective sorting and discharging device K. Detect and
It is configured to sort out good and bad items.

Since the present invention has the above-described configuration, operation, and method, automation is possible by using a pallet system for the main part of the conveyance process.
It saves labor, and when installing the cord reel, it is easy to position, carry in, and discharge each device, and processing can be performed on the line, and the production per hour is constant, so there is no shortage of production quantity. It also prevents losses due to overproduction, making production management easier, and improving the inspection process from conventional sensory inspection to automated numerical inspection, which improves the reliability of the inspection process and improves quality assurance. In addition to the automation of the inspection process, it helps prevent danger to the human body and improves safety, and eliminates the repetitive work of air drivers, stamps, etc. that required many workers in the assembly line work as in the past. The automation of cord reels has great effects, such as contributing to the improvement of the working environment by keeping it to a minimum, reducing the cost of cord reel production through automation, and providing cord reels of good quality. It is possible to provide an assembly inspection method and apparatus.
