Abstract
The utility model discloses a thin plate clamp which comprises a rectangular plate placing frame. Pressing components are arranged on the plate placing frame. One end of each pressing component is rotatably connected with the plate placing frame, and the other end of each pressing component is provided with a pressing portion. The pressing portion surfaces which are contact with a thin plate are in arc shape. Through holes which are corresponding to positions of pressing components and are used for push rods passing through to push the pressing components rotating are arranged in the plate placing frame. When the push rods push the pressing components, the thin plate is placed on the plate placing frame, then the push rod is removed, and the pressing components press the thin plate. Because the thin plate is transported by the thin plate clamp, damage of the thin plate caused by holding in hand is prevented. In addition, because the contact portion surfaces contacted with the thin plate are arc-shaped, in the clamping process of the thin plate by the pressing portions, damage degree of the surface of the thin plate is very small.

Background technology
Along with the direction of electronic product to miniaturization, densification, high integration and multifunction develops rapidly, printed wiring board is more and more higher to manufacturing requirement.Wherein, slimming is the main development direction of printed wiring board.Slimming is had higher requirement to each flow process production equipment of printed wiring board, especially when equipment need to be tackled thin plate design and avoided artificially production quality being exerted an influence, each equipment of manufacturing printed wiring board often need to adopt automation equipment to tackle, the more employing alloy of thick a little printed wiring board draw-in groove fixes printed wiring board, and continues the step of subsequent treatment printed wiring board.
But for the automation of thin plate, process and be difficult to arrive expected effect, printed wiring plate thickness is at the thin plate that is called of 0.044mm～0.15mm, and lamella thickness is little, and thin plate rigidity is low, flexible.Conventionally people can fix thin plate with draw-in groove or clip, but fracture injury phenomenon still often appears in thin plate.
Utility model content
Based on this, the utility model is to overcome the defect of prior art, provides a kind of and can conveniently clamp thin plate, avoids thin plate injured, the sheet clamp of enhancing productivity.
Its technical scheme is as follows: a kind of sheet clamp, comprise for placing the rectangle of thin plate and put sheet frame, described putting, on sheet frame, be provided with casting die, described casting die one end is rotatably connected with the described sheet frame of putting, the other end of described casting die has the portion of pressing, the portion that the presses surface that the described portion that presses contacts with described thin plate is circular arc, described put on sheet frame, be provided with corresponding with described casting die position for push rod through the through hole that promotes casting die and rotate.
Below further technical scheme is described:
Preferably, described in, putting sheet frame has at least both sides to be provided with described casting die.
Preferably, described in, put on every one side of sheet frame and be equipped with described casting die.
Preferably, described in, put casting die set on sheet frame limit for two or more.
Preferably, described in, the portion of pressing is cylindrical steel bar.
Preferably, described casting die and described in put between sheet frame and be provided with extension spring, described extension spring one end is connected with described casting die, the other end of described extension spring is connected with the described sheet frame of putting.
Preferably, described casting die with described in put sheet frame Magnetic Phase and inhale.
Preferably, described casting die has elastic portion.
Below the principle of aforementioned techniques scheme, effect etc. are described:
With push rod, push casting die open, thin plate is put on sheet frame, then remove push rod, with casting die, pressing thin plate, thin plate, by this fixture transportation, is avoided to directly with hand, hold thin plate and caused thin plate damage.Meanwhile, the portion that the presses surface contacting with described thin plate in the utility model is circular arc, with in the portion's of pressing clamping thin plate process, to thin plate, causes the degree of surface damage extremely little.

Embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 3, a kind of sheet clamp, comprise for placing the rectangle of thin plate and put sheet frame 10, described putting, on sheet frame 10, be provided with casting die 20, described casting die 20 one end are rotatably connected with the described sheet frame 10 of putting, and the other end of described casting die 20 has the portion of pressing 22, described in press the portion that presses 22 surfaces that portion 22 contacts with described thin plate and be circular arc, as shown in Figure 4, described put to be provided with on sheet frame 10 corresponding with described casting die 20 positions for push rod, pass and promote the through hole 11 that casting die 20 rotates.
With push rod, push casting die 20 open, thin plate is put on sheet frame 10, then remove push rod, with casting die 20, pressing thin plate, thin plate is transported to desired location by this sheet clamp, avoid directly with hand, holding thin plate and cause thin plate damage.Meanwhile, in the utility model, the portion that presses 22 surfaces that contact with described thin plate are circular arc, with in the portion's of pressing 22 clamping thin plate processes, to thin plate, cause the degree of surface damage extremely little.
In the present embodiment, described in put on every one side of sheet frame 10 and be equipped with described casting die 20, therein in an embodiment, described in put sheet frame 10 and have at least both sides to be provided with described casting die 20.The described casting die set on sheet frame 10 limits 20 of putting is two, and plural casting die 20 can certainly be set.The described portion 22 that presses is for cylindrical steel bar.As shown in Figure 5, described casting die 20 and described in put between sheet frame 10 and be provided with extension spring 30, described extension spring 30 one end are connected with described casting die 20, the other end of described extension spring 30 is connected with the described sheet frame 10 of putting.An embodiment therein, as shown in Figure 6, casting die 20 described in the utility model with described in put the method that sheet frame 10 also can adopt Magnetic Phase to inhale chucking power be provided, by this chucking power, described thin plate is steadily fixed on and is put on sheet frame 10.An embodiment therein, as shown in Figure 7, described casting die 20 has elastic portion 24, and elastic portion 24 is not limited in the particular location of casting die 20, for after removing push rod, because elastic portion elastic shrinkage provides the chucking power of clamping thin plate.
