Description

Detailed Description of the Invention A. Purpose of the Invention (1) Field of Industrial Application The present invention relates to a component pick-up and press-fitting device for picking up a component from its mounting position and press-fitting it into a press-fitting position of a mating member.

(2) Prior Art In an automobile assembly line, some parts are assembled manually, for example, the work of press-fitting a hub unit cap into a hole of a hub unit bearing assembled to a knuckle of a suspension is manually performed. That is, after the operator picks up the hub unit cap on the parts placement pallet and puts it into the hole of the hub unit bearing on the assembly pallet, the hub unit cap is put on by using a manual air hammer. It is designed to be press-fit into the hole.

By the way, in order to save labor and improve work efficiency, automation of work in an automobile assembly line has become widespread. Therefore, automation is desired for the work of assembling the parts such as the hub unit cap as described above.

(3) Problems to be solved by the invention In an automobile assembly line, the parts pallet on which parts are placed and the assembly pallet that fixedly supports the parts on the other side into which the parts are press-fitted are automatically transported and stopped. However, even if an attempt is made to automatically stop these pallets at the set position, the stop position will deviate from the set position and an error will inevitably occur.

When attempting to automate the parts pick-up and press-fitting work, if there is an error in the stop position of the pallet in this way, there will be a relative misalignment between the parts pick-up press-fitting device and the part or the mating member. It becomes impossible to automatically pick up parts or perform automatic press-fitting work using the press-fitting device.

The present invention has been made in view of such circumstances, and an object thereof is to automatically pick up a component or remove a component even if the stop position of the component placement pallet or the assembly pallet deviates from the set position. An object of the present invention is to obtain a component pickup press-fitting device capable of surely performing automatic press-fitting to a mating member.

B. Configuration of the Invention (1) Means for Solving the Problem In order to solve this problem, a parts pick-up and press-fitting device of the present invention has a first position for picking up parts on a parts placement pallet and the parts on the assembly pallet. A vertically movable main body that moves between a second position in which it is press-fitted into the other member, a tubular centering member supported by the main body so as to be movable in all horizontal directions, and a lower end below the open lower end of the centering member. A press-fitting member that is vertically slidably fitted into the inner peripheral surface of the centering member so that a part of the part protrudes, and the press-fitting member is provided on the press-fitting member and sucks the component at the first position and at the second position. And a support member that is connected and supported to the main body through an ascending / descending driving means so as to be capable of being vertically moved relative to the centering member, and that suspends and supports the press-fitting member through a spring. A centering member or a press-fitting member, which is supported by the support member and includes a press-fitting generator that applies a press-fitting force downward to the press-fitting member to press-fit the component sucked by the pick-up member into the mating member. When descending, it cooperates with at least one of the component, the component mounting pallet, the mating member and the assembly pallet to regulate the component pick-up position at the first position and the component press-fitting position at the second position. It is characterized in that it constitutes a position regulating means.

(2) Operation According to the component pick-up and press-fitting device of the present invention configured as described above, the component placement pallet on which the conveyed component is placed and the mating member on which the component is press-fitted are fixedly supported. When the mounting pallets are automatically stopped at the parts pick-up and press-fitting work of the assembly line, the body of the parts pick-up and press-fitting device is moved to the first position for picking up parts.
In this case, when the parts placement pallet is stopped after being slightly displaced from the set position, the parts are also slightly displaced from the regular position.
Therefore, when the main body moves to the first position, a relative displacement occurs between the pick-up member and the component. In this state, when the press-fitting member provided with the pick-up member for supporting the component is moved in the direction of approaching the component, the centering member is not affected by either itself or the press-fitting member and the component or the component mounting pallet. By cooperating with either one, it moves so as to absorb the relative positional deviation in the direction orthogonal to the component press-fitting direction. Therefore, the pick-up member accurately follows the position of the component and is automatically centered. As a result, the pick-up member can accurately support the part.

After supporting the parts, the main body presses the parts into the second
Moved to a position. In this case, since the assembly pallet is slightly displaced from the set position and stopped, the mating member is also slightly displaced from the normal position. Therefore, when the main body moves to the second position, a relative displacement occurs between the component and the press-fitting position of the mating member. In this state, when the press-fitting member moves toward the mating member to press-fit the component, the centering member cooperates with itself or the press-fitting member and the mating member or the assembly pallet. Thus, it moves so as to absorb the relative positional deviation in the direction orthogonal to the component press-fitting direction. For this reason, the parts are automatically centered by accurately following the press-fitting position of the mating member, and as a result, the press-fitting member accurately presses the parts into the mating member due to the pressure input of the pressure input generator. Come to do.

A piston 35 is fitted in the internal space of the press-fitting member 33 so as to be movable in the vertical direction, and the piston 35 is constantly urged upward by a compression spring 36. In the normal state, the piston 35 is held in contact with the step portion 33b formed on the inner wall 33a of the press-fitting member 33. And
A chamber 33c is formed above the piston 35.

A passage 33e is formed in the upper end wall 33d of the press-fitting member 33 to connect the chamber 33c with the outside. Also the piston 35
A suction pad 37 which is a pick-up member of the present invention is provided at the lower end of the suction pad 37, and the suction pad 37 and the passage 33e are connected by a hose 38. Further, the passage 33e is connected to the negative pressure source 40 via the switching valve 39. On the other hand, a passage 33g is formed in the side wall 33f of the press-fitting member 33, and this passage 33g is connected to a high pressure air source 42 via a switching valve 41. A recess 33h having a predetermined size is formed at the lower end of the press-fitting member 33, and the suction pad 37 is located in the recess 33h. Thus, the hub unit cap pick-up and press-fitting section 3 is configured.

The force input generator 4 includes an air hammer 43 that is firmly supported by the support bracket 19. This air hammer 4
3, the piston 44 is directed downward and the press-fitting member 33
Is arranged on the axis line of, and the lower end of the piston 44 is in contact with the upper end of the press-fitting member 33. In that case, press-fitting member 3
The air hammer 43 does not move even if 3 moves back and forth and left and right.

Next, the operation of the present embodiment configured as described above will be described with reference to FIGS.

In FIG. 7, in the previous step, the knuckle 45L, the splash guard 46L, the spindle ring 47L, and the hub unit bearing 48L are integrally assembled by the nut 49L, and the hub unit bearing 48L is further equipped with a brake disc 50L and four wheel bolts 51.
L, 51L, ... Assembled together with the assembly for the left rear suspension to which the assembly is attached, and the assembly for the right rear suspension assembled in the same manner as the assembly fixedly supported on the assembly jigs 52a, 52a. Attachment pallet 52 and a pair of left and right hub unit caps 53L, 53
R and the component placement pallet 54 placed on the receiving members 54a, 54a are conveyed in synchronization with each other in the arrow direction in FIG.
When the vehicle stops at the set position on the vehicle assembly line, the Cartesian coordinate robot 5 is activated by detecting the stop. The robot 5 positions the main body 2 of the hub unit cap pick-up and press-fitting device 1 at the first position above the hub unit cap 53L for the left suspension of the component mounting pallet 54.

Next, the cylinder 29 operates and the piston rod 29a rises, so that the cap 30 is removed from the hole 27e. As a result, the centering member 31 is unlocked and can move in the front-rear and left-right directions, that is, in the entire horizontal direction orthogonal to the component pickup press-fitting direction.

In FIG. 6, the main body 2 of the hub unit cap pick-up and press-fitting device 1 is lowered by the robot 5 so that the lower end of the centering member 31 comes into contact with the upper end of the receiving member 54 a of the component mounting pallet 54. Further, when the main body 2 is to be lowered, the centering member 31 is not lowered any more, and only the first base plate 6 contracts the compression spring 11 and is lowered. Then, when the stopper 8 moves by the distance x and comes into contact with the lower bracket 10a, the contact is detected by an appropriate detection means (not shown), and the robot 5 moves to the main body 2
Stop descending.

Next, the cylinder 17 is operated and the piston rod 18 is extended, the press-fitting member 33 is projected, and the lower end thereof is received by the receiving member 54.
Insert into a. The lower end of the press-fitting member 33 that has been fitted contacts the peripheral edge of the upper surface of the hub unit cap 53L, and the operation of the cylinder 17 is stopped. When the center of the press-fitting member 33 and the center of the receiving member 54a are slightly deviated from each other, the centering member 31 is movable in the front-rear and left-right directions, so that it is formed on the lower end of the press-fitting member 33 and the inner surface of the receiving member 54a. By cooperating with the inclined surface 54b, the centering member 31 is guided and moved in a direction in which the positional deviation is absorbed, and the press-fitting member 33 is accurately made to follow the position of the receiving member 54a for centering. Therefore, the lower end of the press-fitting member 33 is surely fitted into the receiving member 54a. As a result, the suction pad 37 provided on the press-fitting member 33 is arranged at an accurate position with respect to the hub unit cap 53L.

Next, the switching valve 41 is opened, the high pressure air in the high pressure air source 42 flows into the chamber 33c, and the piston 35 descends against the compression spring 36. Then, when the suction pad 37 comes into contact with the hub unit cap 53L, the switching valve 41 is closed, and further lowering of the piston 35 is stopped. Next, the switching valve 39 is opened and the negative pressure of the negative pressure source 40 is introduced into the suction pad 37, and the suction pad 37 sucks the hub unit cap 53L. In that case, the suction pad 37 accurately sucks and supports the hub unit cap 53L, and since the vacuum is used, the hub unit cap 53L is surely sucked and supported regardless of the material.

With the suction pad 37 suction-supporting the hub unit cap 53L, the robot 5 raises the main body 2 and the cylinder 17 operates to raise the press-fitting member 33 and the suction pad 37. At the same time as this operation, the cylinder 29
Is activated, the piston rod 29a is extended, and the cap 3
0 is fitted in the hole 27e and the center link member 31 is locked. In that case, even if the center of the cap 30 and the center of the hole 27e are slightly deviated from each other, the lower end peripheral portion of the cap 30 and the inclined surface 27f of the hole 27e cooperate with each other, so that the cap 30 is securely fitted.

In this state, the robot 5 attaches the main body 2 to the pallet 52
To a second position above. In that case, since the centering member 31 is locked, the press-fitting member 33 and the suction pad 37 are also locked and do not rock back and forth and left and right. Then, the cylinder 29 is actuated to operate the cap 3
0 and the hole 27e are disengaged and the centering member 31 is unlocked.

As shown in FIG. 7, when the robot 5 lowers the main body 2, the inclined surface 31 at the lower end of the centering member 31.
d contacts the tips of the four wheel bolts 51. Further, when the main body 2 descends, the compression spring 11 contracts and the stopper 8 comes into contact with the lower bracket 10a. Upon detecting this, the robot 5 stops the lowering of the main body 2. When the center of the centering member 31 and the center of the hub unit bearing 48 are slightly deviated from each other, the centering member 31 is in a state of being able to move forward, backward, leftward, and rightward, and the centering member 31 is urged downward by the compression spring 11. Since the centering member 31 cooperates with the inclined surface 31d and the wheel bolt 51, the centering member 31 is moved in the front-rear and left-right directions following the position of the hub unit bearing 48. In this way, the press-fitting member 33 and the hub unit cap 53L are positioned such that their respective centers coincide with the center of the hub unit bearing 48.

When the cylinder 17 operates and the press-fitting member 33 descends in this state, the lower end of the hub unit cap 53L uniformly contacts the upper edge of the hole 48a of the hub unit bearing 48.
At the same time, the cylinder 29 operates and the cap 30 opens the hole 27.
The centering member 31 is locked by being fitted into e. Next, the switching valves 39 and 41 are switched, and the high pressure air in the chamber 33c and the negative pressure in the adsorption pad 37 are released. Therefore, the piston 35 is raised by the urging force of the compression spring 36, and the suction pad 37 moves to the hub unit cap 53L.
Get away from.

Next, the air hammer 43 is actuated to apply the pressure input to the press-fitting member 33, and the press-fitting member 33 press-fits the hub unit cap 53L into the hole 48a of the hub unit bearing 48 as shown in FIG. To do. Thus, the hub unit bearing 48 has a hub unit cap 53L.
Is pressed in accurately.

Next, the cylinder 17 raises the press-fitting member 33 and the robot 5 raises the main body 2. At the same time, the cylinder 29 is operated and the cap 30 is fitted into the hole 27e,
The centering member 31 is locked. Then, the robot 5 moves the main body 2 to the first position above the hub unit cap 53R for the right suspension. The hub unit cap 53L for the left suspension described above
By performing exactly the same operation as in the case of
The hub unit cap 53R on the right side is accurately press-fitted into the hole 48a of the hub unit bearing 48.

Since the hub unit caps 53L and 53R are different in size depending on the vehicle type, as shown in FIG. 9, the press-fitting member 33 and the hub unit caps 53 of different sizes correspond to various vehicle types. The dimension of the lower end and the stroke length of the piston 35 are set so as to allow the stroke.

Next, a second embodiment according to the present invention will be described with reference to FIG. The same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 10, a kunet 55, which is a pick-up member of the present invention, is attached to the lower end of the piston 35 provided in the press-fitting member 33. That is, as the pick-up member of the invention of the present application, the vacuum suction pad 37 is used in the first embodiment described above, whereas the magnet 55 is used in the present embodiment, which is different from the second embodiment. The structure is exactly the same as that of the first embodiment.

Although the embodiment of the present invention has been described in detail above, the hub unit cap pick-up and press-fitting device according to the present invention is not limited to the above-described embodiment, and deviates from the present invention described in the scope of claims for utility model registration. It is possible to make various small design changes without any need.

For example, in each of the above-mentioned embodiments, the present invention is applied to the case where the hub unit caps 53L and 53R are press-fitted into the holes 48a of the hub unit bearings 48L and 48R. The present invention can also be applied to the case of press-fitting a part that is fitted into a hole or a recess formed in the.

Further, in each of the above-described embodiments, the parts are picked up by the cooperation of the press-fitting member 33 and the receiving member 54a of the parts placement pallet 54 and the cooperation of the centering member 31 and the wheel bolts 51 attached to the unit bearings 48L and 48R. Positioning means for restricting the position and the press-fitting position of the parts are configured, but for obtaining the positioning means, for example, cooperation between the centering member and the parts placement pallet or cooperation between the press-fitting member and the assembly pallet. Various combinations are conceivable.

Further, the present invention can be used not only for press-fitting parts in the rear suspension but also for press-fitting not only automobiles but also other parts.

Furthermore, although the air hammer 43 is used in order to obtain the driving force of the component in the above-mentioned embodiment, other devices for generating a pressure input may be used.

C. As described above, according to the present invention, when the main body is moved to the first position, even if there is a displacement between the pick-up member and the parts on the parts placement pallet, the centering member and the press-fitting member. The centering member moves horizontally when either the component itself or the press-fitting member cooperates with either the component or the component mounting pallet to perform positioning when the component is lowered to approach the component. Since the positional deviation can be automatically absorbed by appropriately moving, the pick-up member is automatically centered at the position of the component on the component placement pallet, and the component can always be accurately adsorbed and picked up.

Next, when the main body moves to the second position, even if there is a positional deviation between the pick-up member and the mating member on the assembly pallet, the centering member and the press-fitting member are lowered to move the component to the mating member. When the centering members are brought close to each other, the centering member is appropriately moved in the horizontal direction by positioning by cooperating with either the self-pressing member or the mating member or the mounting pallet. Since the displacement can be automatically absorbed, the press-fitting member is automatically centered at the press-fitting position of the mating member,
The force input of the force input generator allows components to be accurately press-fitted into the mating member.
The press-fitting work can be automated.

Further, in particular, a centering member that is supported by the main body so as to be movable in all horizontal directions is formed into a tubular shape, and the press-fitting member is vertically slidably fitted on the inner peripheral surface of the centering member. Since the member is configured to directly perform the above-mentioned centering function in cooperation with the parts and the like when it descends, the press-fitting member is continuously descended without the centering member being specially retracted even after the centering. Can be quickly picked up or press-fitted, which can contribute to an improvement in work efficiency, and a mechanism for retracting the centering member from the press-fitting member need not be specially provided, so that the structure can be simplified accordingly. .
