Description

Electron gun parts laser welding device {Laser Welding Apparatus of Electron Gun}

The present invention relates to an electron gun component laser welding device, and more particularly to an electron gun component laser welding device for welding the grid and bead support used in the electron gun.

As is well known, the conventional electron gun component laser welding apparatus allows a series of welding operations to proceed using an air cylinder.

In the conventional electron gun component laser welding apparatus, a plurality of air cylinders and sensors are radially installed around a work table, and these air cylinders and sensors are controlled by a controller operated by a program.

Therefore, this means that as the number of processes involved in the welding operation increases, the air cylinder and the operation detection sensor have to be expanded, which makes the facility complicated, takes a lot of time to repair the facility, and generates noise and vibration in the operation of the air cylinder. Deterioration of the working environment is caused.

In addition, the amount of the control program for controlling the mechanism transfer may be enormous, which may cause an error in the program, and a lot of time is consumed for input and modification of the program.

In order to solve this problem, the purpose of the present invention is to move the assembly part for welding and to close the parts from the welding position to the welding standby state, so that the precise synchronized action must be performed. Provided are an electron gun component laser welding device that is controlled by the control method.

In order to achieve this purpose, the present invention provides a plurality of parts to be supplied by each feeder, but when each part arrives in the standby position, the jig is moved by the rotation of the cam so that each part is moved to the welding position and The present invention proposes an electron gun component laser welding device in which a series of steps of moving a jig to a standby position after welding is performed by operation of a cam.

Accordingly, the present invention aims to simplify the electron gun component laser welding device, thereby reducing equipment cost, making maintenance easy, and providing a quiet working environment that greatly reduces the occurrence of vibration and noise.

This invention is described in more detail with reference to the accompanying drawings as follows.

The first part supply part 1 with the part feeder, the first part detection part 2 for detecting the arrival of the first part supply part 1, the second part B supply port 3, 2nd part (B) detection part 4 which confirms arrival of 2 parts (B) (B), the pusher 5 which supplies the 1st part A to jig 18, and jig 18 XY loader 6 for closely contacting the second component (B) (B) to the first component (A) of the first welding position after the first component (A) and the second component (B) (B) In the well-known electron gun component laser welding apparatus which consists of the jig lifting part 7 for raising a furnace, the laser generator 8, and the unloading part 9 which discharges a welded part,

The piston rod 13 is moved forward and backward as the first cam follower 10 'installed on the first cam 10 is lifted on one side of the pusher 5 for supplying the first component A to the jig 18. And the first crank 14,

2-1 cam followers 11 'and 2-2 cam followers installed in the second cam 11 to closely contact the second components B and B to the first parts A of the jig 18. An elevating rod 16 and a second crank 17 for allowing the grip 15 to be raised and lowered and retracted in accordance with the operation of 11 '',

In order to move the jig 18 in which the first parts A and the second parts B and B are in close contact with each other, the third cam 12 and the 3-1 camp follower 12 'and The lifting rods 19 and 3-2 respectively in the camp follower 12 '',

The first cam 10, the second cam 11, the third cam 12 is provided with a rotating shaft 20 to be interlocked.

This invention is described in detail according to the accompanying drawings as follows.

According to the present invention, when the first parts A are supplied one by one from the known first parts supply port 1 and guided by the guide to arrive at the waiting position, the first parts A are connected to the first parts detecting unit 2 at the standby position. The cam rotation motor is operated.

Accordingly, as the rotating shaft 20 rotates, the first cam follower 10 'is first raised by the first cam 10 and then lowered in the drawing. Accordingly, the piston rod is retracted and moved forward by the operation of the first crank 14. At this time, one first part A is advanced to be seated on the jig 18, and the third cam 12 is attached to the third cam 12. As a result, the jig 18 is raised by the jig lifting unit while the 3-1 camper 12 'is raised to be in the standby position.

On the other hand, when the second part (B) (B) is also sequentially supplied from the second part (B) supply port (3) and confirmed by the second part (B) detection unit 4 in the standby position, the second cam (11) 2-1 camp follower 11 'rises as a result of the rotation of the < RTI ID = 0.0 > elevating rod 16, < / RTI > The mounted jig 18 is approached.

Subsequently, the second crank follower 11 ″ operates the second crank 17 by the rotation of the second cam 11, so that the second part B and the second part B are the first parts of the jig 18. By advancing closely to A), the 2nd components B and B are in close contact with the 1st component A on the jig 18. As shown in FIG. At this time, when the laser beam is fired from the laser generator 8, a specific portion where the first part A and the second part are in close contact is heated at a high temperature for a very short time to perform welding. After the welding is completed in this manner, the 3-2 cam follower 12 '' of the third cam 12 is lifted and the jig lifting unit lowers the jig 18 and the lifting bar 19 is lowered. As a result, the welded first and second parts are lowered, moved to the unloading part 9, and are discharged after being sorted as good or bad by the sensor, and repeated parts as described above. Welding work is done.

In addition, in the present invention, but shown an application example of the component shown in Figure 3 for convenience, of course, can be applied to a variety of other gun related parts.

In this way, in the present invention, in the laser welding of the first and second parts, the entire process of unloading after the first and second parts reach the standby position is implemented by the cam, so that the signal input from the sensor is analyzed by the program. Therefore, the structure is simpler than the conventional method of supplying the control power to the air cylinder, and the maintenance of the equipment is easy, and the pneumatic equipment such as the case of using the air cylinder is unnecessary, thereby reducing the equipment cost. .

In addition, there is almost no operation noise and vibration as in the case of using an air cylinder, so that the working environment can be maintained comfortably.

In terms of the operation speed of the facility is much faster than the conventional one to improve the production efficiency, and to reduce the time required for input and modification of the program can contribute to the productivity.

In addition, by greatly reducing the amount of control program for controlling the mechanism transfer, it is possible to contribute to the simplification of the whole control program, simplifying maintenance, greatly reducing the occurrence rate of errors, and improving the reliability of operation. It works.
