Abstract
The invention provides a clamping device for a clamp used for cutting a silicon wafer. The device comprises a fixing block, a clamping block, a first clamping component and a second clamping component, wherein the clamping block is movably arranged in the fixing block; one end of the first clamping component vertically passes through one end of the fixing block, and is in thread connection with the fixing block to form a whole; one end of the second clamping component is transversely inserted into the other end of the fixing block, and is in thread connection with the fixing block; a flange at one end of the second clamping component is matched wit a groove at one end of the clamping block; and the outer circumference of the flange is in clearance fit with the inner circumference of the groove. The clamping device is convenient to use; the clamping is operated manually, so the clamping force is uniform to protect the silicon wafer from broken; and after a single clamping device is broken, the clamping device can be replaced respectively, so the cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of clamping device, particularly a kind of clamping device that cuts silicon chip with anchor clamps belongs to the technical field of silicon chip machining tool.
Background technology
Before the silicon chip processing, earlier silicon crystal slate to be cut split and become block.In the existing silicon chip cutting equipment,, generally adopt fixedly modes such as cylinder clamping, mobile cylinder clamping or Rodless cylinder clamping to the clamping mode of silicon crystal slate.In the above-mentioned clamping mode, the mode of fixing to clamp is used the most general, but its cost is high; The Rodless cylinder translational speed is slow, and owing to be monolateral clamping, clamping force is inhomogeneous, makes silicon crystal slate draw damage easily, and the silicon wafer piece of appearance processing is lack of standardization, like phenomenons such as joint-cutting and surperficial out of plumb; Overcome above-mentioned phenomenon though move cylinder clamping, had the high problem of cost.
Summary of the invention
It is even that technical problem to be solved by this invention provides a kind of clamping force, and cutting silicon chip with low cost is with the clamping device of anchor clamps.
In order to solve the problems of the technologies described above; A kind of clamping device that cuts silicon chip with anchor clamps of the present invention; Comprise fixed block, clamp, first clamping component, second clamping component; Said clamp is mobilizable to be arranged in the said fixed block, and said first clamping component, one end vertically passes said fixed block one end, and is threaded with said fixed block and is integral; The laterally inserted said fixed block other end of said second clamping component, one end, and be threaded with said fixed block; The flange of said second clamping component, one end matches with the groove of said clamp one end, and the inner peripheral surface matched in clearance of said flange outer periphery face and said groove.
Above-mentioned a kind of clamping device that cuts silicon chip with anchor clamps wherein, is provided with ball between the end face of said groove floor and said flange.
The present invention can realize following beneficial effect:
1, owing to the present invention includes fixed mount, being arranged on the clamping device on the said fixed mount; Said clamping device comprises fixed block, clamp, first clamping component, second clamping component; During clamping, clamping device is moved on to the appropriate location, first clamping component is tightened; End face through first clamping component is pressed on the fixed mount, and clamping device is located; Turn second clamping component again, promote clamp, silicon crystal slate is clamped through second clamping component; During dismounting, as long as second clamping component is oppositely turned, clamp is moved backward, silicon crystal slate is unclamped get final product, therefore, the present invention uses more convenient, and clamping is by manually-operated, and clamping force is even, avoids pressing from both sides silicon wafer bad; And after single clamping device damages, can change individually, greatly reduce cost; In addition, the present invention is made up of the minority parts, and is with low cost.
2, owing to be provided with ball between the end face of said groove floor and said flange, when second clamping component rotated, the friction of second clamping component and clamp was rolling friction; Frictional force is less; Avoid the damage of second clamping component and clamp, thereby, service life of anchor clamps prolonged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of fixed block of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of cutting silicon chip of the present invention is used anchor clamps, comprises that fixed block 21, clamp 22, first clamping component 23, second clamping component, 24, the first clamping components 23 are rod member, and the outer peripheral face of rod member is provided with external screw thread; Fixed block 21 is an integrated member; Fixed block 21 surfaces are provided with first groove 211; This first groove 211 links to each other with fixed mount 1; Horizontal thread hole 214, passage 212 that fixed block 21 1 ends are provided with the passage 212 that clamp 22 is installed and second clamping component 24 is installed communicate with screwed hole 214, and the other end of fixed block 21 is provided with the longitudinal hole 213 of installation first clamping component 23, and the inner peripheral surface of longitudinal hole 213 is provided with internal thread; Second clamping component 24 is a rod member, and this rod member outer peripheral face is provided with external screw thread, and an end of rod member is provided with flange 241; Clamp 22 is the block member of rectangle; One end of clamp 22 is provided with groove 221; Said clamp 22 is arranged in the said fixed block 21; Clamp 22 passes the longitudinal hole 213 of said fixed block 21 1 ends with 21 movable connections of fixed block, said first clamping component, 23 1 ends, and is threaded with said fixed block 21 and is integral; Said second clamping component, 24 1 ends insert in the screwed hole of said fixed block 21, and are threaded with said fixed block; The flange 241 of said second clamping component, 24 1 ends matches with the groove 221 of said clamp 22 1 ends, and the inner peripheral surface matched in clearance of said flange 241 outer peripheral faces and said groove 221.The present invention uses more convenient, and clamps by manually-operated, and clamping force is even, avoids pressing from both sides silicon wafer bad; And after single clamping device damages, can change individually, greatly reduce cost; In addition, the present invention is made up of the minority parts, and is with low cost.
In order to prolong service life of the present invention, can between the end face of said groove 221 bottom surfaces and said flange 241, be provided with ball 25, owing to be provided with ball 25 between the end face of said groove 221 bottom surfaces and said flange 241; When second clamping component 24 rotates; Second clamping component 24 is rolling friction with the friction of clamp 22, and frictional force is less, avoids the damage of second clamping component 24 and clamp 22; Thereby, prolonged service life of anchor clamps.
During clamping, fixed block 21 is moved on to the appropriate location, first clamping component 23 is tightened, the end face through first clamping component 23 is pressed on the fixed mount, and clamping device is located; Turn second clamping component 24 again, promote clamp 22, silicon crystal slate is clamped through second clamping component 24; During dismounting, as long as second clamping component 24 is oppositely turned, clamp 22 is moved backward, silicon crystal slate is unclamped get final product.
In sum, it is even that the present invention has clamping force, with low cost, easy for installation, flexible and advantage of simple structure.
Here description of the invention and application is illustrative, is not to want that therefore, the present invention does not receive the restriction of present embodiment with scope restriction of the present invention in the above-described embodiments, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the present invention's protection.
