The device of a kind of stable holding pcb plate
Technical field
The utility model relates to surface-mounted integrated circuit clamping device, particularly the device of a kind of stable holding pcb plate.
Background technology
Printed circuit board (PCB), also known as printed circuit board (PCB), it is the supplier of electronic devices and components electrical connection, its the development history of existing more than 100 year, its design mainly layout design, adopts the major advantage of circuit card to be the mistake greatly reducing wiring and assembling, it is to increase automatization level and productive labor rate, pcb board has a very wide range of applications, and is applied in a lot of electronics. In recent ten years, rapidly, the gross output value, ultimate production occupy the first in the world in pairs in China's printed circuit board (PrintedCircuitBoard is called for short PCB) manufacturing development. Owing to electronic product makes rapid progress, rate war changes the structure of supply chain, and China has industry distribution, cost and the market advantage concurrently, has become the printed circuit board production base that the whole world is the most important. Printed circuit board develops into dual platen, multi-ply wood and flexible sheet from individual layer, and constantly develops to high precision, high-density and high reliability direction. Continuous reduced volume, minimizing cost, raising performance so that printed circuit board, in the development process of future electronic product, still keeps powerful vitality. Following printed circuit board manufacturing technology development trend develops to high-density, high precision, fine pore, thin wire, Small Distance, highly reliable, multiple stratification, high-speed transfer, light weight, slim direction in performance. Pcb board clamping device common at present is mainly for the production of the clamping of wiring board when assembling on line, but shape, circuit card that size is certain are being clamped by this device, the surface-mounted integrated circuit of different size can not be clamped, therefore design a kind of structure pcb board clamping device that is simple, workable and pcb board and band stop-return slot that different size can be clamped flexibly and have very much realistic meaning. Existing chucking device can not be very stable clamping, the pcb board of different size can not be adapted to.

Clamping parts can move on support bar, and clamping parts, after being subject to the power of runner, drive bolt rotary, and then drives clamping parts to move left and right, the position of adjustment clamping parts like this, it is possible to the pcb board of clamping different size size.
As preferred version of the present utility model, described clamping parts comprise Holding seat and holding hand, described holding hand is sleeved in Holding seat, it is provided with groove in described Holding seat, spring it is provided with in groove, one end of described spring is connected to the bottom of groove, and the other end is connected to the bottom of holding hand. Spring can well give holding hand power, and holding hand can move in the groove of Holding seat, and what make that pcb board can be more stable is clamped between holding hand and Holding seat, makes follow-up processing more accurate.
As preferred version of the present utility model, described Holding seat and holding hand are aluminium alloy or iron or copper. Adopting the material of metal, be not easily out of shape, hardness is also relatively big, is applicable to selecting.
As preferred version of the present utility model, described support bar material is stainless steel or aluminium alloy. Adopting the material of metal, be not easily out of shape, hardness is also bigger.
As preferred version of the present utility model, described spring is high-density rubber bar. Highdensity rubber bar can also provide same tension power, and cost is lower, changes and also facilitates.
As preferred version of the present utility model, described gripper frame material is plastics or stainless steel or aluminium alloy. Adopt the material of metal, not easily it is out of shape.
As preferred version of the present utility model, described runner is fixedly connected on screw rod. Runner is fixedly connected on screw rod, it is possible to reduce the loss of power, more firmly.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: structure is simple, be easy to operation, clamping is stablized, be not easily out of shape, improve efficiency has saved cost.
