This application claims priority to Chinese Patent Application No. 201621125591.6 filed on Oct. 14, 2016, which is incorporated herein by reference it its entirety.
The present disclosure relates to the field of display panel manufacturing technology, and more particularly to a target mounting fixture.
As a consumable for coating film, a target has a limited lifespan, and it needs to be replaced regularly. A time for replacement work largely determines an Overall Equipment Effectiveness (OEE) of a device, and then determines a production capacity of the device. At present, a target mounting operation is mainly achieved by hoisting and supporting the target through a crown block. For a current target mounting fixture, a fixing fixture is provided at each of an upper part and a lower part of the target, and then the fixture at the upper part of the target is mounted with a hoisting apparatus to realize a hoisting operation of dismounting and mounting of the target.

Obviously, the following embodiments are merely a part of, rather than all of, the embodiments of the present disclosure, and based on these embodiments, a person skilled in the art may obtain the other embodiments, which also fall within the scope of the present disclosure.
Unless otherwise defined, any technical or scientific terms used herein shall have the common meaning understood by a person of ordinary skills. Such words as “first” and “second” used in the specification and claims are merely used to differentiate different components rather than to represent any order, number or importance. Similarly, such words as “one” or “one of” are merely used to represent the existence of at least one member, rather than to limit the number thereof. Such words as “connect” or “connected to” may include electrical connection, direct or indirect, rather than being limited to physical or mechanical connection. Such words as “on/above”, “under/below”, “left” and “right” are merely used to represent relative position relationship, and when an absolute position of an object is changed, the relative position relationship will be changed too.
In order to solve the technical problem that different locations of the fixture and the target need to be realized by moving the crown block, the progress of operation is limited by the crown block and the operating efficiency is low, the present disclosure provides in at least one embodiment a target mounting fixture capable of saving operating time for mounting the target to improve an operating efficiency.
As shown in
According to the target mounting fixture provided by the present disclosure, when dismounting and mounting the target 10, the target fixing frame may be hoisted through a crown block to hoist the target 10 to a target carrier located at an operating location, and then a moving mechanism is used to move the target carrier so as to satisfy requirements for different locations during the dismounting and mounting process of the target 10. After finishing hoisting the target 10 to the target carrier, the usage of the crown block ends, the crown block is only responsible for hoisting and handling, and is no longer responsible for hoisting the target 10 to different locations during the dismounting and mounting process of the target 10. Therefore, during the dismounting and mounting process of the target 10, the crown block may be used to hoist other targets 10 to save the operating time and improve the operating efficiency.
Thus it can be seen that, the present disclosure may realize a reduction of using hours of the crown block, as a bottleneck device, during mounting the target 10, realize a quick dismounting and mounting of the target 10, and realize a reduction of time for replacing the target 10, thus improving the OEE of the device and increasing the production capacity of the device.
Before describing the target mounting fixture according to embodiments of the present disclosure, first of all, a description of a dismounting and mounting process of the target will be carried out. Generally, a plurality of targets are mounted on a target back plate, when the targets is dismounted or mounted, the target back plate mounted with the plurality of targets is usually dismounted from, or mounted on a coating device.
