Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a press processing apparatus for wiring boards and the like. More specifically, the present invention relates to improvements in equipment for handling and pressing single-sided printed wiring boards, flexible wiring boards, nameplates, and the like.

[Prior art and its problems] Press processing equipment has various structural designs depending on the workpiece, but basically the lower die on the fixed side and the lower die on the elevating side are molded together. It is equipped with a press mold consisting of an upper mold, and a lifting mechanism is attached to the upper mold.

Conventionally, in such a press working apparatus, one in which the elevating gate structure is a cam or a crank mechanism is known.

However, the problem with conventional press processing equipment is that it is not possible to finely control the lifting and lowering of the upper mold, making it unsuitable for processing workpieces that require a high degree of processing viscosity, such as wiring boards. There is.

[Object of the Invention] The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide a press processing apparatus equipped with an elevating mechanism that can be delicately controlled.

[Structure of the Invention] In order to achieve the above-mentioned object, a press working apparatus according to the present invention includes a press mold consisting of a lower mold on a fixed side and an upper mold on an elevating movable side that are matched with each other, In the press working equipment which is provided with a mechanism, the lifting mechanism is characterized in that a lifting boss, which is vertically attached to an upper die holder to which an upper mold is attached, is moved up and down by a servo motor via a linking member. Adopt the configuration.

[Function] In the above configuration, the servo motor used as the drive source for the lifting movement of the upper mold enables free control of the driving force for the lifting movement by the controller 1 to roll, which can freely control the rotational force including the number of rotations,
Since the lifting boss vertically installed on the upper mold holder directly transmits the controlled driving force to the upper mold, delicate control of the raising and lowering of the upper mold is possible.

[Example] Hereinafter, an example of a press processing apparatus according to the present invention will be described based on the drawings.

In the illustrated embodiment of the press working V apparatus, the machine body 1 has a structure in which a base 12 is provided on a machine frame 11, and the base 1
A press die 2 is installed on the top of the press die 2.

The press mold 2 has a lower mold 21 which is molded together. The lower mold 21 is placed and fixed on the base 12, and the upper mold 22
is movable up and down with respect to the lower mold 21 by a lifting mechanism 3.

The lower mold 21 is equipped with a die or a punch on its mold matching surface, and its position is regulated by a positioning shaft 4 provided on the base 12, and a fastener 5 provided on the base 12.
It is fixed in place.

The upper mold 22 is equipped with a die or a punch on its mold matching surface, and is connected to the lifting mechanism 3.

The elevating mechanism 3 includes an upper mold holder 31 to which the upper mold 22 is attached, an elevating boss 32 vertically installed on the upper mold holder 31, a linking member 33 attached to the lower end of the elevating bosses 1 to 32, and a linking member 33. and a servo motor 34 connected to the servo motor 34.

The upper mold holder 31 has a positioning shaft 4 similar to the base 12.
, a fastener 5, these positioning shafts 4.
The upper die 22 is fixed by the fastener 5. Note that the upper mold 22. A knockout mechanism 6 is incorporated into the upper die holder 31 to prevent the workpiece W from adhering to the upper die 22 during pressing. The lift boss 32 passes through the base 12, and has threaded parts 32A, 3 above and below it.
2B, and the upper threaded portion 32A is fixed to the upper mold holder 31 with a nut 32G. The linking member 33 includes an elevating plate 33Δ fixed to a threaded portion 32B at the lower part of the elevating post 32 with a nut 32C, a geared rotation nut 33B rotatably supported by the elevating plate 33A, and a geared rotating nut 33B fixed to the machine frame 11. It consists of a geared rotating nut 333 and a screw guide 33C that is screwed together. The servo motor 34 is supported by the lifting plate 1-33A, and a gear 343 fixed to its shaft 34A meshes with the geared rotating nut 333. FIG. 3 shows a modification of the area around the linking member 33, in which the geared rotating nut 33B is fixed to the lifting plate 33A as a fixed nut 33B' without a gear, and the screw guide 33C is rotatably mounted. Gear 33 supported and coaxially fixed to machine frame 11
Gear 343 of the servo motor 34 supporting D on the machine frame 11
It meshes well with that.

In the illustrated embodiment, the above-mentioned press mold 2. Lifting mechanism 3
In addition to this configuration, two sets of optical sensors 7 consisting of a light emitting part 71 and a light receiving part 72 are incorporated into the press mold 2, and the reference mark provided on the workpiece W is searched to move the workpiece W to the lower mold 21. It is configured so that it can be aligned. Further, a vacuum suction hole 8 is provided approximately at the center of the lower mold 21 and around the light receiving portion 72, so that a workpiece W aligned with the lower mold 21 can be suctioned and fixed. Furthermore, a work table 9 is provided on the base 12 to be flush with the lower die 21, and
A movable arm mechanism X for supplying the workpiece W and a transfer robot Y for recovering the product after processing the workpiece W are provided. A console unit Z having a built-in controller for electrical connection and control is provided to automatically feed the workpiece W.

In the press processing apparatus configured as described above, the workpiece W is supplied to the press mold 2 by the movable arm mechanism X, aligned by the optical sensor 7, and fixed by suction by the suction hole 8. Pressing will be performed using press mold 2. The product is then transported by the transport robot Z! ! ! 2.

In this series of machining operations, the upper mold 22 of the press mold 2 is raised and lowered by the lifting mechanism 3. That is,
When the servo motor 34 is driven, the gear 34B fixed to the shaft 34A rotates, and the geared rotating nut 33B (FIG. 1) or the gear 33D rotates.

By rotating the screw guide 33C (Fig. 3), the elevating plate 33A is raised and lowered, and the elevating post 32. Upper mold holder 31. The upper mold 22 will be raised and lowered.

The fact that the driving source for this lifting and lowering is the servo motor 34 allows delicate control of the rotational force including the rotational speed, and this control is performed by the linking member 33. Lifting boss 32. For example, the lifting speed of the upper mold 22 is directly transmitted to the upper mold 22 via the upper mold holder 31.

It becomes possible to freely control the press pressure and the stopping position of the upper die 22.

[Effects of the Invention] As described above, the press processing device according to the present invention can finely control the lifting and lowering of the upper mold, so it improves the processing accuracy of the product, and is adaptable to workpieces made of various materials and can be used for general purposes. It has the effect of improving sex.
