CONSTITUTION:The head of each of parts 21 comes into contact with the lower part of each support pipe 14 of a parts suction head 12 being on standby at the upper part of a holding model 4. At this time, each support pipe 17 of another parts suction head 16 is being touched to the head of the part 21 inset in a receiving hole 8 of an attitude control model 7, giving air suction action to both these heads 12 and 16, whereby these parts 21 are attracted to both support pipes 14 and 17. Afterward, the head 12 so far opposed to the parts holding model 4 is transferred onto the attitude control model 7 and the head 16 so far situated on the attitude control model 7 is transferred onto a work 9 respectively. Here, each head is made to go down and the air suction is stopped whereby these parts 21 so far held by respective support pipes 14 and 17 are dropped down, and inserted into the receiving hole 8 of the attitude control model 7 and a small hole 20 of a base material 19 on the work 9, respectively.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for assembling parts by inserting them into holes drilled in a base material, such as rivets or screws, which have thin legs protruding from their heads. Specifically, the present invention relates to an apparatus for assembling parts of equipment, which performs the work of inserting a rivet into a hole in a bearing adhesive retainer.

[Technical background of the invention and its problems]

The parts feeding device in a conventional assembly machine is provided with a plurality of scooping arms in a hopper that can swing up and down, and scoops the parts in the hopper with its head upward using the arms to form a continuous chute with each arm. be guided to. At the end of the chute, take out each of the parts that have been sorted and arrange them in the same way as the fitting position for the base material to be assembled, and guide them with a chute such as a hose to the position where the base material is fixed. It is made up like this. However, this type of equipment requires several steps from the hopper to the base material, and has the disadvantage that efficiency cannot be improved.

[Purpose of the invention]

The purpose of the present invention is to scoop out a required number of parts stored in a hopper and arrange them at a required pitch, and to fix the arranged parts onto a workpiece while holding them by suction force. The collet chuck used in the past has been improved by being configured so that the holding position of the parts being held while being transported is adjusted to a state suitable for insertion into the hole in the base material. The purpose of the present invention is to provide an apparatus that can efficiently assemble a plurality of parts within a narrow range by eliminating the need for

[Summary of the invention]

In order to achieve the above purpose, the component holding mold lifts the parts stored in the hopper from the bottom of the hopper, and scoops out the required number of parts in a predetermined arrangement at once. Each scooped-out component is held at the tip of the support tube by suction means and transported toward the base material on the workpiece, but during transportation, the components held in the support tube do not necessarily align with the axis of the support tube. Since the parts are not held vertically along the support pipe, the parts are once dropped into the attitude control mold, and the parts in the attitude control mold are again sucked to the end of the support tube and conveyed toward the base material. In addition to inserting the part that has been sucked into the hole in the base material as it is, the action of dropping the part into the posture control mold and the action of putting the part into the base material are performed all at once, and the action of taking the part from the part holding mold is performed. It is configured so that the movement of picking up parts from the posture control type is also carried out at the same time.

[Embodiments of the invention]

Therefore, to explain this invention by way of an embodiment, as shown in FIG. 1, a component aligning section 1 consisting of a hopper 2, a component holding mold 4, etc. is provided on the left side of the figure, and a posture control mold 7 is fixed in the middle part. The workpieces 9 fixed to the rotary disk 1o are arranged on the right side, and the axes of the component holding mold 4, the posture control mold 7, and the workpieces 9 in the upright direction maintain the same distance, respectively.
The upper surfaces of the component holding mold 4, posture control mold 7, and workpiece 9 in the raised state are located on substantially the same horizontal plane. Furthermore, a component suction head 12 is placed above both molds 4 and 7.
．． 16 are integrally connected to each other by arms 18, and are movable left and right as well as vertically. With this device,
In this method, parts are aligned, conveyed, corrected in their support posture, and loaded into the base material, and the posture correction and loading steps are performed at the same time. Therefore, to explain in detail the structure of each part, the hopper 2 is fixed on an elevating drive device 3 using a cylinder or the like, and a component holding mold 4 is placed in the center of the hopper 2 and moved up and down from the bottom of the hopper 2 to slightly above the upper opening. The holding mold 4 is connected to an operating rod 5 of the lifting drive device 3 that moves up and down. The upper end of the component holding mold 4 is formed into a chevron shape, and a plurality of grooves 6 into which the legs of the component 21 fit are provided on the slope of the chevron shape. The arrangement of the grooves 6 is similar to the arrangement of the small holes 20 into which the parts 21 of the base material 19 are inserted. If the base material 19 is a retainer, the small holes 20 are provided at equal intervals in the circumferential direction, so the grooves 6 are provided at equal intervals in the radial direction.

The posture control type 7 has a plurality of receiving holes 8 in the board body in the vertical direction and is open in the same manner as the arrangement of the small holes 20 in the base material 19, and the upper part of the receiving holes 8 is shaped like a trumpet and is opened downward from the upper end. When the component 21 is dropped into the receiving hole 8, the head of the component 21 is pulled into the entrance of the hole 8, and the leg is vertically inserted into the hole 8. It fits in so that it stands up.

A plurality of workpieces 9 are fixed at equal intervals to a rotary disk 10 that rotates intermittently, and a base material 19 is placed on the upper surface of the workpiece 9, and each of the workpieces 9 corresponds to each small hole 2o of the base material 19. The hole 11 into which the leg portion of the component 21 can fit is open.

The component suction head 12 has a space 13 inside the board, and a plurality of support tubes 14 protruding from the space to the lower surface of the board in an arrangement similar to the arrangement of the small holes 20 in the base material 19. A port 15 for suctioning air communicating with the space 13 is provided on the disk body, and the tip of each support tube 14 is formed so as to attract the component 21 by the suction force of the air. Other parts suction head 16
This head has a structure similar to that of the head 12, but a support tube 17 is provided in a protruding manner. Also, an arm 18 that connects both heads 12゜16.
is connected to a drive unit (not shown) having an appropriate structure that reciprocates left and right and moves up and down. The shape of each lower end of the support tubes 14, 17 is formed according to the shape of the head of the component 21, as shown in the drawings. Note that the attraction force may not be based on the vacuum method but may also be based on magnetic force.

The present invention has the above structure, and a large number of parts 21 are put into the hopper 2 in a state where the descending part holding mold 4 is covered, and the base material 19 is fixed on the workpiece 9 and placed in a predetermined position. By raising the component holding mold 4 while it is being sent to the position and stopping, each concave groove 6 provided at the upper end of the holding mold 4 is removed.
The part 21 is held inside with the head fitted upward,
The head of the component 21 contacts the lower end of each support tube 14 of the component suction head 12 that is waiting above the holding mold 4 . At this point, each support tube 17 of the other component suction head 16 is in contact with the head of the component 21 fitted into the receiving hole 8 of the attitude control type 7, and the suction action of air is exerted on both heads 12 and 16. By providing the bearing tube 14. of each head 12.16. i7
The component 21 is sucked to. Then, after raising both heads 12.16 and pulling out the parts 21 from both dies 4 and 7, both heads 12.16 are moved to the right side in the figure, and the head 12 facing the part holding die 4 is controlled in attitude. The head 16 that was on the posture control mold 7 is moved onto the workpiece 9 onto the mold 7, and the heads 12 are lowered and the air suction is stopped. The part 21 that was being held falls and is inserted into the receiving hole 8 of the posture control mold 7 and the small hole 20 of the base material 19 provided on the workpiece 9.

Thereafter, both heads 12 and 16 rise and return to their original positions, during which time the component holding die 4 descends once and rises again to hold the component 21 and wait. ．．
Reference numeral 16 repeats the operation of descending again and picking up the parts, thereby continuously performing the assembly operation. Further, during the above-described assembly operation, when the component 21 is attracted to the support tube 14 by the component holding die 4, the component 21 is not necessarily attracted to the support tube 14 perpendicularly, but often tilts. This is because the concave groove 6 of the component holding mold 4 is provided on the inclined surface.However, since the concave groove 6 is provided on the sloped surface, the parts can be reliably scooped out by the vertical movement of the holding mold 4, and the excess can be removed. Parts can be scavenged.

On the other hand, since the receiving hole 8 of the attitude control type 7 is formed in a trumpet shape, when the part 21 is dropped into the hole 8, even if the base material is inclined, it will be guided by the trumpet-shaped hole and will be securely inserted. The straightened parts are straightened into vertical striations, and then the straightened parts are placed in the support tube 17.
When suctioning is performed, the tube 17 is suctioned in a state where it hangs straight down without being inclined. Since the suction posture of the component is corrected in this way, the component can be directly and smoothly inserted into the small hole of the base material without any hindrance. However, when inserting the component into the small hole, it is a matter of course that each support tube 17 should be lowered to reliably face the small hole in the base material, and this needs to be taken into consideration in the design of the machine.
