Referring to Fig. 6, its rearview for being schematically shown as silicon rod clamper 25.In specific implementation, as shown in fig. 6, clamp arm drives Mechanism further comprises: folding gear 255, gear drive 256 and driving source 257.

Opening and closing gear 255 is set in corresponding clamp arm 254.Gear drive 256 has and the folding in clamp arm 254 The groove that gear 255 engages.Driving source is connected to gear drive 256, for driving gear drive 256 to move.In one kind On implementation, gear drive 256 is rack gear, which is located at the centre of two clamp arm 254, in rack gear respectively for Corresponding tooth is engaged with the folding gear 255 in two clamp arm 254 in being respectively equipped on two lateral surfaces of the clamp arm 254 of two sides Line, driving source 257 may be, for example, driving motor or or cylinder.

In this way, according to above-mentioned implementation, in practical applications, when that need to realize 254 clamping of clamp arm, by as driving source Driving motor or cylinder driving moved up as the rack gear 256 of gear drive, drive what both sides engaged to open by rack gear 256 It closes gear 255 and makees outward turning movement, folding gear 255 drives clamp arm 254 during revolving outside (folding gear 255 and clamp arm 254 can Connected by shaft) make decentralization movement to be transferred to clamping state by releasing orientation；Conversely, when that need to realize that clamp arm 254 is unclamped, by Driving motor (or cylinder) driving as driving source is moved down as the rack gear 256 of gear drive, is driven by rack gear 256 The folding gear 255 of both sides engagement makees pronation, and folding gear 255 drives (the folding gear of clamp arm 254 during revolving inside 255 can be connect with clamp arm 254 by shaft) raising up acts to be transferred to releasing orientation by clamping state.Certainly, it above are only one Embodiment is not intended to limit the working condition of silicon rod clamping piece 253, in fact, " upward ", " outward turning " in aforementioned, " under Put ", " downward ", " inward turning ", " raising up " and " release " and " clamping " state change can be according to the structure and fortune of clamp arm 254 Make mode, clamp arm driving mechanism construction and have other changes.

Just as it is known by a person skilled in the art that silicon single crystal rod or polycrystalline silicon rod are directed to, due to long silicon rod originally or just The specification of grade silicon ingot (large scale silicon ingot) is different, carries out truncation operation to long silicon rod originally or carries out evolution work to first grade silicon ingot Industry and truncation operation are different, are bound to so that between silicon single crystal rod and polycrystalline silicon rod, between silicon single crystal rod individual and polycrystalline silicon rod Size difference between individual is totally different, in view of silicon rod clamper 25 be for erect placement status under silicon rod 100 clamp, Therefore, for silicon rod clamper 25, the influence of aforementioned dimensions difference mainly just shows the length difference opposite sex of silicon rod to silicon rod Whether the silicon rod clamping piece 253 in fixture 25 can correspond to the secret worry for being clamped to silicon rod.Even exempt above-mentioned silicon rod folder to reduce Gripping member 253 may can not be clamped to the risk of silicon rod.

In one implementation, silicon rod clamper 25 uses fixed silicon rod clamping piece, that is, the first of commutation carrier 23 Silicon rod clamping piece 253 as much as possible is fixedly installed on mounting surface in a manner of vertical, and, it is adjacent in these silicon rod clamping pieces 253 The spacing of two silicon rod clamping pieces 253 is as small as possible, in this way, using these silicon rod clamping pieces 253 can cover all kinds specification it is long The silicon rod of degree.For example, participating in clamping using silicon rod clamping piece 253 more on commutation carrier 23 if the length of silicon rod is longer； If the length of silicon rod is shorter, clamping is participated in using silicon rod clamping piece 253 less on commutation carrier 23.

And in other implementations, silicon rod clamper 25 uses movable silicon rod clamping piece, that is, the of commutation carrier 23 Silicon rod clamping piece 253 is arranged in activity in a manner of vertical on one mounting surface, due to, silicon rod clamping piece 253 is movable design, because This, the quantity of silicon rod clamping piece 253 can be greatly decreased, and generally two or three can meet.In this way, utilizing these activities Formula silicon rod clamping piece 253 can cover all kinds scale lengths silicon rod.For example, moving silicon rod clamping if the length of silicon rod is longer Part 253 extends the clamping spacing of two silicon rod clamping pieces 253；If the length of silicon rod is shorter, silicon rod clamping piece 253 is moved, is contracted The clamping spacing of short two silicon rod clamping pieces 253.In implementation of the silicon rod clamper 25 using movable silicon rod clamping piece, it is It is smooth smoothly up and down to adjust position convenient for movable silicon rod clamping piece, it is installed using the fixture in silicon rod clamper 25 Part 251 plays the guiding role of boot activity formula silicon rod clamping piece 253, and in a kind of achievable mode, fixture installation part 251 can Using guide post structure, clamp arm mounting base 252 is then using the movable block structure for being socketed on guide post structure.Specifically, as folder The guide post structure of tool installation part 251 includes erectting setting and two parallel guide posts, as clamp arm mounting base 252 Two perforations corresponding with two guide posts in the guide post structure or two clips are then equipped in the activity block structure. According to perforation, the movable block is sheathed on the guide post and can realize and slides along the guide post.According to clip, institute Movable block is stated to be clipped on the guide post and can realize along guide post sliding, wherein in practical applications, the clip An at least half part for the guide post can be clipped on.

For the silicon rod clamper 25 of movable silicon rod clamping piece 253, different change case is also had.It is clamped with two silicon rods For part 253, in an alternative embodiment, a silicon rod clamping piece 253 in two silicon rod clamping pieces 253 is movable sets Counting another silicon rod clamping piece 253 then is fixed design, in this way, being all by the movable design of movement in practical applications That silicon rod clamping piece 253 adjust the clamping spacing between the silicon rod clamping piece 253 of fixed design.It can from above To know, silicon rod 100 is to erect to place, therefore, no matter the scale lengths of silicon rod, always the bottom of silicon rod 100 can be relatively easy to determine , it is thus preferable to, that silicon rod clamping piece 253 being located above in two silicon rod clamping pieces 253 can be designed as activity Formula, in this way, need to only adjust the position of the silicon rod clamping piece 253 of top.It is described for the movement for realizing silicon rod clamping piece 253 The silicon rod clamping piece 253 of movable design can be equipped with guiding driving mechanism.Movable design can be driven using guiding driving mechanism Silicon rod clamping piece 253 along fixture installation part 251 move up and down.
