Base part

1 is a perspective view showing an insulator attachment device of the present invention.

The base part 10 has an area enough to arrange the frame 5 of the monitor, and the support part 11 is formed in a horizontal direction with the frame on the frame top of the monitor. The support 11 has a function of allowing the transfer unit, which will be described later, to be connected and transferred.

Conveying part

In FIG. 1, the conveying unit 20 conveys in the same direction as the direction in which the insulator 3 is attached to the monitor frame 5. To this end, the transfer unit 20 is provided with a transfer base 25 on one side of the support 11. The conveyance base 25 is connected to the support part 11 in such a manner that a cylindrical bar-shaped guide bar 24 connected up and down in the conveying direction is inserted, and slides in the conveying direction along the guide bar 24 to be conveyed. To be able. The guide base 26 is formed in the transfer base 25 so that the guide bar 24 can be inserted therebetween, and can also be screwed with the transfer screw 23 between the guide grooves 26 of the transfer base 25. The transfer screw groove 28 is formed. (See Figure 12)

The feed screw 23 is preferably arranged between a pair of guide grooves in the same direction as the guide groove 26, and the feed motor 21 is integrally connected in one direction so that the feed screw 21 is removed from the feed motor 21. Rotational force is configured to be transmitted throughout the screw. Since the transfer screw 23 is for power transmission, it may be formed as a square screw, and the transfer screw groove 28 of the transfer base 25 coupled with the transfer screw 23 is also formed with a square screw.

Therefore, when the transfer screw 23 rotates in response to the power transmission from the transfer motor 21, the transfer unit 20 converts the rotational force into linear motion by the transfer screw groove 28 to straighten the transfer base 25. Exercised.

The transfer unit 20 serves to transfer the transfer base in the attachment direction when the insulator 3 is temporarily attached or the insulator is attached to the attachment position of the monitor frame.

Connection

The connection part 30 is formed below the transfer part 20, and is connected to the transfer part 20 so as to move in a direction perpendicular to the transfer direction and the plane of the transfer part, and at the same time, move up and down.

For this purpose, the connection part 30 is formed at the lower part of the transfer part 20, in particular, the transfer base 25. As shown in FIG. 3, the connection base 33 is supported to be movable by a guide bar 34 installed below the transfer base 25 in a direction perpendicular to the same plane as the transfer direction. The connection part transfer motor 31 arranged in the connection base is installed in the upper part of the connection base 33 and the lower part of the transfer base 25. The connecting part transfer motor 31 allows the screw shaft to rotate to screw the screw shaft groove (not shown) formed in the lower part of the conveying part, thereby converting the rotational force into linear motion. However, it is not limited to such a transfer motor, and it can be easily understood by those skilled in the art that a hydraulic or pneumatic cylinder having such a function may be used. (See Figure 12)

The vertical movement function on the same plane as the conveying direction of the connecting portion 30 is used to temporarily attach the insulator 3 to the attachment portion and move the attachment portion to the attachment position again. That is, the path between the temporary attachment and the actual attachment is converted.

In addition, the connection part 30 includes a shangdong copper frame 43 for moving downward so that the attachment portion formed under the connection portion can attach the insulator. Shanghai copper frame 43 is connected to be movable in the vertical direction by the guide bar 45 formed in the lower portion of the connecting base 33, the cylinder 41 is formed on one side of the shandong copper frame 43, One side of the cylinder is fixed to the connection base 33, and the other side, which is the moving part of the cylinder, is connected to the shanghai copper frame 43. (See Figure 12)

Therefore, the shandong copper frame 43 is able to move downward with respect to the connection base 33, and thus can be adjusted so that the attachment portion can contact the insulator.

Attachment

1 and 2, the attachment portion 50 is formed in a disk shape so as to be rotatable on one side of the lower portion of the connection portion 30, that is, the shankdong frame 43. To this end, the attachment portion 50 includes an attachment plate 60 formed in a disc shape to have a circumferential length equal to the length of the attachment position of the monitor frame.

The attachment plate 60 is formed in a disc shape in which a portion is cut as shown in FIGS. 1 and 2. The diameter of the disc is preferably formed such that the attachment length and the circumferential length are the same according to the attachment length of the monitor frame.

A plurality of vacuum holes 62 are formed at circumferential intervals of the attachment plate 60 at predetermined intervals. The vacuum hole 62 is connected to the rotating shaft 64 in the radial direction of the attachment plate 60, so as to form a vacuum of a predetermined size by an external vacuum pump (not shown). An adhesive surface for actual attachment is formed only on one surface of the inductor, and a separate attachment means must be provided for temporary attachment to the circumferential surface of the attachment plate 60. Accordingly, the vacuum hole 62 is formed on the circumferential surface. The insulator is to be temporarily attached through the vacuum adsorption method.

In addition, the attachment plate 60 may be reversed in the rotational direction at the time of the temporary attachment and the actual attachment, it is connected to the rotary motor 51 for such forward or reverse rotation.

Attachment portion 50 includes a close contact means 70 for holding the end of the insulator 3 in close contact with one end of the circumferential surface from the cutout of the attachment plate 60. 2 and 5, the close means 70 is formed in a b-shape to be in close contact with the bent portion 68 formed by the cut portion 67 and one end of the circumferential surface of the attachment plate 60. It includes a close contact frame 77. The close contact frame 77 should be connected to move in the vertical direction and the left and right directions (left and right direction of Figure 5) with respect to the bent portion (68). Therefore, in order to move the close contact frame 77 in the vertical direction, the top and bottom close contact cylinder 71 is mounted on the close contact frame. The top and bottom contact cylinder 71 is fixed to the a-shaped fixed frame 79 located above the close contact frame, and the fixed frame and the close contact frame 77 are in a state in which the close contact frame moves up and down with respect to the fixed frame. It is connected.

In addition, the close contact frame 77 and the fixed frame 79 is connected to the front and rear close contact cylinder 73, wherein the front and back close contact cylinder 73 moves the close contact frame and the fixed frame in the front and rear direction. The front and rear contact cylinder 73 is fixed to the attachment plate 60 so that the attachment plate can be used as a support to advance the contact frame forward and backward.

work

3 to 7, the operation of the insulator attachment device of the present invention will be described.

First, the insulator 3 is positioned on one side of the base 10 as shown in FIG. 3. At this time, the frame of the monitor is arranged on the other side, the insulator 3 is arranged in a position parallel to the attachment position of the monitor frame. The insulator 3 is cut in advance by the width and length to be attached, and several are arranged side by side.

Next, the attachment part 50 is moved to one end of the insulator, that is, the insulator start position. The attachment part 50 may move in the x and y directions on a plane by the transfer part 20 and the connection part 30, and move to an appropriate initial position. (Figures 3 and 4)

Next, the insulator is temporarily attached to the circumferential surface of the attachment portion with the attachment portion 50 in contact with the insulator 3. In this case, as shown in FIG. 5, the insulator is temporarily attached to the circumferential surface of the attachment portion by the contact means. That is, as shown in Fig. 5 (a) the corner portion of the attachment portion, that is, the cut portion 68 is located at the start position of the insulator (3). Then, as shown in (b), the close contact frame 77 is pushed downward to form a space between the bent portion 68 and the close contact frame 77, and then the front and rear contact cylinder 73 is closed as shown in (c). Pull the contact frame 77 to the right in the drawing. Thereafter, as shown in (d), the upper part of the insulator 3 is pulled upward through the upper and lower contact cylinders 71 to be held in close contact with the starting point of the attachment plate 60 of the attachment part 50.

FIG. 6 illustrates temporarily attaching the insulator 3 to the circumferential surface while the attachment plate 60 is being rotated and simultaneously rotated. After the initial fixing operation by the close means, the insulator is temporarily attached while rotating the attachment plate 60 at the same time as the transfer of the transfer unit 20. The insulator is attached to the attachment plate 60 by vacuum so that a vacuum is formed along the circumference.

On the other hand, the attachment plate 60 has a linear speed v1 at the point of contact with the insulator while rotating itself (hereinafter referred to as rotation speed v1), and when the insulator is attached to the attachment plate, the speed v2 is It is preferable not to be larger than the rotation speed v1. In other words, if the speed of the conveying part is faster than the rotational speed, the insulator cannot be temporarily attached to the circumferential surface of the attaching part flatly. On the other hand, if the speed of the conveying part is set to be slightly slower than the rotating speed, the insulator is pulled slightly and the vacuum is sucked to the peripheral surface. The effect of temporarily attaching can be obtained. The attached insulators can be attached so that they do not fold or overlap upon actual attachment.

Next, as shown in FIG. 7, the attachment part 50 is moved to the attachment position of the monitor frame 5, the attachment part 50 is rotated, and the transfer part 20 is moved at the same time to move the temporarily attached insulator to the actual attachment position. Attach it. At the time of attaching, as shown in FIG. 6, it is attached while rotating in the reverse direction unlike the temporary attaching while transferring in the v3 and v4 directions. Since the adhesive part of the insulator is temporarily attached to the outside of the circumferential surface, the insulator is attached to the frame by releasing it while contacting the attachment position with a suitable pressure.

When the insulator is actually attached to the monitor frame, the feed speed v4 is preferably not smaller than the linear speed (rotation speed v3) at the contact portion with the monitor frame due to the rotation of the attachment portion. In other words, if the rotation speed v3 is faster, the overlapping or twisting contact occurs during the bonding process, so that the contacting with a slight extension while pulling forward can increase the contact force and obtain a good contact state.

8 and 9 illustrate an embodiment in which the insulator attachment device according to the present invention operates sequentially. Since the insulator attachment device attaches the insulator while repeatedly performing movement in one direction, it is possible to arrange four insulator attachment devices in sequence and form them as one line in the case of the monitor frame having four sides. At this time, the monitor frame is arranged on the conveyor belt to sequentially move to the attachment device, the attachment device is arranged in the transverse direction and the longitudinal direction respectively to attach the insulator. (Fig. 8) It is also possible to attach two insulators simultaneously in the transverse and longitudinal directions, respectively, a drawing of which is shown in Fig. 9.

10 shows that a plurality of insulator attachment devices according to the present invention are arranged in the attachment position of the frame of the monitor, and at least two or more insulators can be attached to the frame by simultaneously operating these attachment devices. FIG. 10 shows an embodiment in which two horizontal attachment devices and two longitudinal attachment devices are arranged at the same time to attach four insulators at the same time.

The insulator attachment device and the attachment method of the present invention can automatically attach the insulator attached to the inside of the frame of the monitor to reduce labor, improve the insulator attachment quality, and shorten the working time, thereby enabling mass production more. to provide.

In addition, the present invention provides an advantage that the continuous operation is possible to increase the amount of work and mass production of the standardized product, easy to maintain due to the efficient equipment configuration.
