The present invention is an improvement of a jig device for holding an injection molded product in a take-out robot used to take out various molded products such as a TV case or a monitor case molded in an injection molding machine.

The take-out robot has a structure as shown in FIG. 1, and the X-axis 61 is fixed to the base 64. In the X-axis 61, the Y-axis 62 moves to the left and right, and the Y-axis ( In 62), the Z-axis 63 moves back and forth, and the Z-axis 63 operates the jig 65 while itself moving up and down, and separate conveyors for gripping the molded product, drawing it out from the injection molding machine, and transferring it to the next process. All processes placed on the device are carried out automatically.

The present invention is to provide a device in the take-out robot 60 that is operated as described above, to improve the jig 65, to improve the light and durability and to hold any molding.

The conventional jig device has a structure as shown in (a) (b) (c) of FIG. The finger cylinder bracket 4 and the width adjustment bracket 3 are fixed to the upper and side surfaces of the jig base 2 with a normal wrench bolt, and the repeat switch bracket 13 is attached to one side of the jig base 2. The horizontal adjustment bracket 3 is mounted with a cylinder rod mounting bracket 5, which is operated by a thin cylinder 14 and a guide shaft 6 is inserted into the guide bearing 1, is vertically long and has pads at both ends thereof. The support bracket (7), the height adjustment bracket (8) and the width adjustment bracket (19) are mounted in this order, the pad support bracket (9) is provided at the front end of the width adjustment bracket (19), the pad support bracket (9) The sliding bar 10 of the pad 21 elasticized with the spring 16 is inserted into the fixing bushing 11.

The finger cylinder bracket 4 is provided with a finger cylinder 17 by brackets 18 and 18-1, and the finger cylinder 7 is provided with a chuck bracket 20 and a cap 15.

The conventional jig device configured as described above has various problems.

First of all, since all brackets such as the pad jig bracket (7), the pad height adjustment bracket (8), and the width adjustment bracket (19) are made of steel, there is a large load. There is a problem that needs to be large.

In addition, in order to reduce the load, the thickness of these brackets is thinned, but the brackets and pads 21 and the cap 15, which are shocked due to the large capacity of the lifting and lowering of the Z axis, are severely shaken. Therefore, it is not easy to select a position for precisely gripping the product, and thus there is a problem of falling or falling even when moving up and down after the gripping state, and in some cases, the pad height adjustment bracket 8 is bent.

In addition, the cylinder rod mounting bracket 5 operated by the thin cylinder 14 is bent backward when the pad 21 grips the product so that the grip force is very weak and the pad 21 faces only the front side, so that the cylinder 21 is inclined or holes. When holding a lot of perforated products, such as a back case of a TV, the pad 21 is held at a position not perpendicular to the inclined surface, or the suction force is remarkably dropped when absorbing and holding a product with many holes. Problems such as a weakening of the gripping force caused an error of gripping occurred.

Therefore, in order to be able to hold a product with a lot of holes, there is a problem that the pad part including the pad 21 must be fundamentally redesigned and mounted.

In particular, if the position of the cap 15 for gripping the sprues attached to the product is not correctly adjusted, the fixed brackets 18 and 80-1 may be bent backwards, thereby smoothly functioning later. There is a phenomenon that can not be performed, and therefore, the product must be operated while continuously adjusting each time the product is ejected, which also wastes unnecessary time and manpower, causing a significant drop in productivity.

The present invention has been proposed to solve the above problems.

The present invention is to be able to operate the pad to hold the product individually as each single-acting cylinder to strengthen the holding force and various brackets made of aluminum, but the width is slightly wider to reduce the weight and firmly, and to adjust the angle of the pad arbitrarily The purpose of the present invention is to provide a jig device for reinforcing the holding force and to replace a separate pressing plate according to the characteristics of the product, and to solve the problem of bending due to the variable cap.
