Under the conditions of the existing factory building structure and the layout of the coating line, the operation of replacing the target material is as follows: after the film plating machine has the condition of shutdown maintenance, a cathode cover plate of the film plating machine is hung on the target changing trolley by a travelling crane and fixed, and the target changing trolley is turned over to enable the target to face upwards. The rotary target is heavy, and the target must be pulled by a travelling crane, and after an operator separates the target from the cathode end, the travelling crane lifts the separated old target to a designated area. And the working personnel extracts the magnetic bar in the old target material and replaces the new target material, then the new target material is hung on the cathode by the travelling crane, and then the working personnel fix the target material and the end head of the cathode to complete the target replacement work. In the whole process that the old target material is separated from the cathode end and the new target material is fixed with the cathode end, the whole course of the travelling crane is required to be assisted, the cart of the travelling crane is always fixed right above the target changing trolley, other travelling cranes can not pass through the area when carrying out other transfer work, and other work can only be carried out after the target changing work is finished, so that the working efficiency is extremely low, the shutdown maintenance time of equipment is prolonged, and the production cost is increased indirectly.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1-4, the invention provides a device for assisting in replacing a magnetron sputtering rotating target, which comprises a portal frame 4, a target placing trolley 7 and a winch 2, wherein pre-embedded rails 14 are laid on two sides of a target replacing trolley 17, the bottom of the portal frame 4 is slidably placed on the pre-embedded rails 14 on two sides, the winch 2 is installed on a top beam 1 of the portal frame 4 and can slide along the top beam 1, and a transmission end of the winch 2 is connected with a lifting hook 3 through a hanging strip; the target material placing trolley 7 is fixed on one side of the portal frame 4 through a connecting rod 8 and moves along with the portal frame 4, and the target material placing trolley 7 is used for placing the old target material 5.

The pre-buried tracks 14 are laid on two sides of the target changing trolley 17, and the length of the tracks is more than the sum of the length of the target changing trolley 17 and the length of the support base of the portal frame 4 of the device. A steel structure portal frame 4 which takes I-steel as a top beam 1 and is provided with four rail wheels 12 at the bottom is arranged on the rail. The gantry 4 is driven by a motor 10 through a speed reducer 13 and can move forward or backward in the track direction. A winch 2 capable of walking along the length direction of the I-steel is arranged on the I-steel beam of the portal frame 4 (the maximum hoisting weight is more than or equal to 500 kg). One side of a portal frame 4 support is provided with a target material placing trolley 7 connected with the portal frame, a foam pad 6 with a circular groove is arranged on the trolley, and four universal wheels 9 are arranged below the trolley. The target placing trolley 7 moves forwards or backwards along the track direction on the ground along with the portal frame 4.

The operation of replacing the target material by the device comprises the following steps: after the cathode cover plate 16 is reversed on the target changing trolley 17, the portal frame 4 is moved to the middle position of the target changing trolley 17; the target is pulled by the winch 2 through the hanging strip, the old target 5 is separated from the cathode end head 15 by an operator, the old target 5 is hung by the winch 2 and moves to the upper part of the target placing trolley 7 along the direction of the I-shaped steel beam, and the lifting hook 3 of the winch 2 descends to place the old target 5 on the trolley. The operator pulls out the magnetic rod from the old target 5, removes the old target 5 and places a new target on the cart, and then plugs the magnetic rod. The winch 2 hoists the new target material to the cathode end head 15 through the hanging belt, an operator fixes the target material and the cathode end head 15, and the hanging belt is taken down to complete the operation flow of replacing the rotary target material. The portal frame 4 is moved to a position away from the target changing trolley 17, and the cathode cover plate 16 can be lifted away by a crane to perform other work flows after being reversed.

The device has the advantages that in the operation process of replacing the rotary target, after the travelling crane lifts the cathode cover plate 16 onto the target replacing trolley 17, other transportation work needing the travelling crane can be carried out, the target replacing operation can be completed by the device, and the height (about 3m) of the device is far lower than the clearance height (about 7.5m) below the travelling crane, so that the free travelling of the travelling crane is not influenced. During the shutdown maintenance of the coating line, no traveling crane needs to be stopped for a long time at the station of the target changing trolley 17 for changing the rotary target, the target changing efficiency is greatly improved, the total shutdown maintenance time is shortened by about 50 percent, the effective production time of the production line is prolonged, and more production values can be created for enterprises.
