Description

T-type shooting hose for improper fraction type screw and screw fastener with same {T-TYPED SHOOTING HORSE AND SCREWDRIVER FOR FASTENING SCREW OF IMPROPER FRACTION TYPE THEREWITH}

The present invention relates to a T-type shooting hose for improper fraction type screws and a screw fastener having the same, and more specifically, a screw having a diameter of a screw head larger than a trunk length (screw length) (hereinafter, referred to as an "integral fraction" T-type shooting hose for fastening " improper fraction "

In general, screw fastening operations in mass production lines are performed either manually or by semi-automated operations. For example, many operators use hand tools, such as wrenches or screwdrivers, to fasten screws to specified assemblies or, in more advanced work, motor-driven power tools. These methods of screw fastening actually require a large number of skilled workers and thus increase manufacturing costs. In addition, the screw fastening operation of these methods has a limitation in the working speed, so the delay time becomes too long in the process of fastening a plurality of screws at the same time.

Accordingly, the assembly fixed to the jig (Jig) is assembled using an automatic screw fastening system for the reasons of productivity improvement, quality uniformity of assembly, and labor cost reduction.

This automatic screwing system automatically aligns randomly placed screws, transfers them through a screw feed hole through a straight feeder (screw feeder) to a screw distribution hole, and separates one by one from the screw distribution hole by compressed air. A hose-type chute is supplied to the electric screwdriver through mounting, and then the screw is tightened by advancing the electric screwdriver to the screw hole of the assembly by a pneumatic cylinder or a server motor.

As such, the introduction of automatic screw fastening devices in line with the automation trend of non-manual processes in mass production lines is contributing to the reduction of labor costs and personnel management, increased productivity, and other reliability of precision work and production lines. .

On the other hand, in the automatic screw fastening device according to the prior art, the fastening head is in the form of a jaw (inlet) portion, the fastening head housing is fixedly mounted in the form of a fastening head in which the screw is loaded in the jaw (jaw) through the inlet consist of. The jaw-type fastening head has a structure in which jaws on both sides of the fastening head must be opened when the screw descends together with the bit to fasten the screw before the target point.

As a prior art related to the above-mentioned automatic screw fastening device, Korean Patent No. 10-604345 discloses an invention named "ball-type fastening head", which will be described with reference to FIG. Let's explain.

1 is a view showing an automatic screw fastener equipped with a ball-type fastening head according to the prior art.

In this case, the display may be switched by the display changeover switch, and the preset function may be stored.

Specifically, in the screwing system for improper fractional screw according to the embodiment of the present invention, the screw feeder controller 150 includes a voltage and frequency adjustment switch 151, a setting change storage switch 152, and a voltage and frequency variation switch 153. ) And the power switch 154, it is possible to adjust the voltage and frequency for driving the screw supply (130).

On the other hand, Figure 21 is a view showing a driver controller in the screwing system for improper fraction screw according to an embodiment of the present invention, Figure 22 is a method of operating a driver controller in the screwing system for improper fraction screw according to an embodiment of the present invention. A diagram for explaining.

 Figure 21a) is a photograph showing the RDT-30IV, Figure 21b) shows the input power, the output power and the output signal, the driver controller 160 in the screw fastening system for improper fractional screw according to an embodiment of the present invention. ) Is a controller for driving the electric driver 111 of the screw fastener, and may be, for example, a model name RDT-30IV.

Specifically, the driver controller 160 supplies power of 20 to 30V to the electric driver 111, inputs a torque up, and outputs a screw transmission signal to the screw supplier 130.

In addition, the driver controller 160 may be equipped with a brake switch, which is an overload protection circuit, and may turn on / off the electric driver 111 by an external contact.

The driver controller 160 may adjust the descent start time of the pneumatic cylinder, and also adjust the descent time and the screw feed time of the pneumatic cylinder.

In addition, the driver controller 160 may adjust the initial rotation time which is a fitting time of the + shape of the screw of the electric driver 111 and the cross shape of the dedicated bit.

 Specifically, referring to FIG. 22, an operation method of the driver controller 160 in the screw-fastening system for the fractional screw according to the embodiment of the present invention is as follows.

TD0 is a terminal for adjusting the cylinder descent start time. When the screw is finished and the start switch of the electric screwdriver 111 is released, the pneumatic cylinder starts to move up and down for delivery of the next screw. At this time, the TD0 may adjust the timing until starting the vertical movement, for example, the adjustment time may be within 0.1 ~ 5 seconds.

Next, TS1 is a terminal for adjusting the cylinder lowering time and the screw feeding time, and adjusts the time when the cylinder is fully extended and sent to the catcher. For example, the adjustment time range may be 0.1 to 1 second.

Next, TM1 is a terminal for adjusting the driver rotation time. The TM1 adjusts the time for rotating the driver in combination with the cylinder lift in order to smoothly fit the screw and the bit (adsorption).

On the other hand, in the screw fastener for improper fraction type screw according to the embodiment of the present invention, the fastening time of one screw is about 2 seconds, and as a shooting and seating error rate, no error occurred during the 100 shooting tests. Air pressure of 0.4 ~ 0.5Mpa was used.

As a result, according to the embodiment of the present invention, when the dividing screw having a diameter of the screw head larger than the length of the trunk portion (screw length) is supplied through the screw feeder, the impinging dividing screw can be fastened precisely to the fastening object. In addition, through the shooting hose (Shooting Hose) corresponding to the shape of the improper fraction screw can be easily supplied to the screw fastener without error.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
