Description

Apparatus for manufacturing electromagnetic wave covering shield

The present invention relates to an apparatus for manufacturing an electromagnetic shielding shield, which is accommodated in a monitor and prevents the emission of electromagnetic waves therein.

The electromagnetic shielding shield is installed on the monitor to prevent electromagnetic waves generated from various electronic components installed inside the monitor. Such electromagnetic shielding shields are used in most monitors and are manufactured by bending and bonding conductive plate sheets.

However, in order to manufacture the electromagnetic shielding shield, the conductive plate-like sheet had to be bent and then joined to another part. This process was done after bending the conductive plate-like sheet once bent, and then moved to the bonding press apparatus. Therefore, the time required to move the bent conductive sheet sheet to another press device, the number of people operating it, and the place for storing the bent conductive sheet sheet before bonding were needed, which is reflected in the cost of the conductive sheet sheet. It became the factor which lowered productivity.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an electromagnetic shielding shield manufacturing apparatus that can be performed at the same time bending and bonding process.

Hereinafter, the operation of the bending press apparatus according to the present invention.

7 to 12 is a view showing a process of bending and bonding the conductive plate-like sheet in the shielding shield manufacturing apparatus of the present application.

First, as shown in FIG. 7, in a state where the rising support block 120 is raised to the height of the A-corresponding surface 111, the upper surface A of the conductive plate-shaped sheet 10 is fixed to the main fixing block 110. ) And the rear surface (B) on the lifting support block (120). At this time, the position fixing pin 111a of the A-corresponding surface 111 is inserted into the hole of the upper surface A so that the plate-shaped sheet 10 is seated at the correct position on the main fixing block 110.

Next, as shown in FIG. 8, while the main lowering block 210 descends to the A-corresponding surface 111, the AA-corresponding surface 211 of the main lowering block 210 is the upper portion of the plate-shaped sheet 10. The surface A is brought into close contact with the A-corresponding surface 111. As a result, the plate-shaped sheet 10 is fixed to the main fixing block 110.

Next, as shown in FIG. 9, the second falling block 240 descends to the E-corresponding surface 115, and the EE-corresponding surface of the second falling block 240 is positioned above the E-corresponding surface. Both side edge inclined surfaces E of the plate sheet 10 are pressed against each other. Then, both side edge inclined surfaces E are bent at the top surface A, and both side surfaces C are bent downward at both side edge inclined surfaces E, as shown in FIG. 10.

Next, as shown in FIG. 10, while the first falling block 220 descends to the B-corresponding surface 121, the BB-corresponding surface 221 of the first falling block 220 becomes a B-corresponding surface ( 121) the back surface (B) of the plate-shaped sheet 10 which is located in the upper portion is primarily in close contact. Subsequently, the rising support block 120 descends while the first falling block 220 is intact, and the next first falling block 220 descends further by a few millimeters, thereby decreasing the rear surface B of the plate-shaped sheet. Bending close to the B-corresponding surface 112, as shown in FIG.

Next, as shown in FIG. 12, the first falling block 220 rises and rises to an initial position. Thereafter, the side block 140 moves to the main fixing block 110, whereby the DD-corresponding surface 142 forms the D-corresponding surface 113 of the plate-shaped sheet and the FF-corresponding surface 143 of the plate-shaped sheet The bent edge F is formed by bending the edge. Subsequently, when the side block 140 returns to the initial position, as shown in FIG. 13, the joining blades F are bent and the joining protrusions P are inserted into the joining holes H of the joining blades F.

Next, as shown in FIG. 14, in the state where the joining protrusion P of the joining blade is sandwiched in the joining hole H of the rear portion, the sliding block 153 is moved toward the main fixed block by the driving cylinder 159. Move. Then, the joining rod 154 fixed to the sliding block 153 continues to move through the first sub-fixing block 151, and eventually the tip 155a of the caulking end 155 provided at the end of the joining rod 154. ) Is in close contact with the bonding groove (112a) while unfolding the bonding projection (P). That is, since the tip 155a has a triangular pyramid shape and is installed at the caulking end 155, as shown in FIG. 6, the tip 155a spreads the joining protrusion P to cover the edge of the joining hole H. In this way, the bonding blade F is bonded to the rear surface, and the electromagnetic wave shield 10 'as shown in FIG. 3 is completed.
