Abstract
The utility model relates to a lower gripping device for a glass substrate loading frame. The lower gripping device is characterized in that a convex blocky body is arranged at one end of the lower gripping device, the convex end of the blocky body is closed, a threaded counter bore is arranged at the other end of the blocky body, the axis of the threaded counter bore and the central line of the blocky body are on the same straight line, and the blind end of the counter bore is close to the convex end of the blocky body. When the lower gripping device is in use, a screw penetrates through the glass substrate loading frame to be matched with the threaded counter bore of the lower gripping device, and the lower gripping device is fixed on the glass substrate loading frame. The thread section of the screw is positioned in the threaded counter bore of the lower gripping device and is not in the exposure state, so that the thread section of the screw is difficultly plated with coating material (such as tin indium oxide) after being filmed for a plurality of time. Therefore, when the screw is removed to correspondingly adjust the specific position of the lower gripping device, the screw is easy to remove, the lower gripping device is not easy to damage and can be continuously used, so that the lower gripping device has longer service life and low use cost.
Description
Technical field
The utility model relates to a kind of glass substrate loading frame lower clamp.
Background technology
At present, glass substrate loading frame generally adopts a plurality of anchor clamps and a plurality of lower clamp fixing glass substrates gone up in the vacuum plating industry, each lower clamp through the tapped through hole opened on it and the screw retention of spinning in this tapped through hole on glass substrate loading frame.Lower clamp adopts high temperature material to process, and price is higher.
Usually, in plated film is produced, adjust accordingly through the particular location of knockout screw according to the specification of glass substrate to lower clamp.Because of what be provided with on the lower clamp is tapped through hole, and the thread segment of screw is in exposed state, so through behind the plated film repeatedly, the thread segment of screw can be plated Coating Materials (like tin indium oxide) and chap, makes screw be difficult to dismounting.Because of this, can only take the way dismantled by force to screw, often cause lower clamp to damage and can't continue using, the work-ing life of lower clamp is shorter, like this, will often lower clamp be changed, and has increased use cost.
The utility model content
The utility model technical problem to be solved provides a kind of long service life, glass substrate loading frame lower clamp that use cost is low.
For addressing the above problem; The utility model provides a kind of glass substrate loading frame lower clamp; It is that an end has protruding blocks, has that protruding end to be closed on the blocks, and the other end on the blocks has screw-threaded counterbore; The common straight line of the axis of screw-threaded counterbore and the medullary ray of blocks, the cecum of this counterbore is near that protruding end is arranged on the blocks.
For can concise description for the purpose of the problem, below the utility model glass substrate loading frame lower clamp be all abbreviated as this lower clamp.
During use, pass glass substrate loading frame, cooperate, this lower clamp is fixed on the glass substrate loading frame with the screw-threaded counterbore of this lower clamp through screw.
Be in because of the thread segment of screw in the screw-threaded counterbore of this lower clamp and no longer be in exposed state, so through behind the plated film repeatedly, the thread segment of screw is difficult for being plated Coating Materials (like tin indium oxide).Like this, when through knockout screw the particular location of this lower clamp being adjusted accordingly, screw is easy to dismounting, and this lower clamp is fragile and can continue to use yet, so that the work-ing life of this lower clamp is long, use cost is low.
Description of drawings
Fig. 1 is the structure of this lower clamp and uses scheme of installation.
Embodiment
Through embodiment and accompanying drawing thereof the utility model is done explanation in further detail below:
Referring to Fig. 1; This lower clamp is that left end has protruding 11 blocks 1; There is the left end of convexity 11 to be closed on the blocks 1; Right-hand member on the blocks 1 has screw-threaded counterbore 12, the common straight line of the medullary ray of the axis of screw-threaded counterbore 12 and blocks 1, and the cecum of this counterbore 12 is near the left end that has protruding 11 on the blocks 1.
During use, pass glass substrate loading frame 2, cooperate, this lower clamp is fixed on the glass substrate loading frame 2, form draw-in groove 3 between convexity 11 of this lower clamp and the glass substrate loading frame 2 with the screw-threaded counterbore 12 of this lower clamp through the screw (not shown in figure 1).In plated film is produced, glass substrate 4 is put into draw-in groove 3, draw-in groove 3 can play fixing and spacing effect to glass substrate 4.
Be in because of the thread segment of screw in the screw-threaded counterbore 12 of this lower clamp and no longer be in exposed states, so through behind the plated film repeatedly, the thread segment of screw is difficult for quilt and is plated Coating Materials (like tin indium oxide).Like this, when through knockout screw the particular location of this lower clamp being adjusted accordingly, screw is easy to dismounting, and this lower clamp is fragile and can continue to use yet, so that the work-ing life of this lower clamp is long, use cost is low.
