Abstract

The utility model discloses a polycrystalline silicon C-corner hairbrush polishing machine. A plurality of hairbrushes are utilized to replace original grinding wheels to polish polycrystalline silicon, wherein the hairbrushes are arranged on a rotary table of the machine in an annular array mode. Compared with an original polishing technology, according to the scheme, the quality of products is improved, the defective rate of the products is reduced, and good social benefits are achieved.

Description

A kind of polysilicon C angle brush polishing machine

Technical field

The utility model relates to a kind of polysilicon C angle brush polishing machine, belongs to the polycrystalline silicon material manufacture field.

Background technology

Polycrystalline silicon rod is after grinding wheel chamfering, and edge surface has angle burr to collapse limit crack or other defect are even arranged, and edge surface is more coarse, needs other operation to carry out polishing to it, and traditional glossing precision can't guarantee, and quality of finish is not high yet.

The utility model content

The utility model replaces the emery wheel mechanism of traditional beveler by a hairbrush, thereby realizes the polishing of the high accuracy high smooth degree at polysilicon C angle.

The utility model is realized by the following method:

A kind of polysilicon C angle brush polishing machine, for the processing polysilicon of polishing; Comprise V-shaped groove, rubbing head, turning cylinder, described rubbing head is arranged on the bottom of V-shaped groove, and the clutch end of rubbing head and turning cylinder is connected, and described rubbing head comprises rolling disc and hairbrush, described hairbrush is arranged on rolling disc, and described rolling disc is fixedly connected with turning cylinder.

As further innovation of the present utility model, a kind of polysilicon C angle brush polishing machine, described hairbrush comprises column bottom support bracket and brush, described brush is fixedly connected with rolling disc by the column bottom support bracket.

As further innovation of the present utility model, be provided with some installing holes of equidistantly arranging with respect to rotary disk center of circle annular on described rolling disc, described hairbrush is arranged in installing hole by the column bottom support bracket.

As further innovation of the present utility model, the quantity of described hairbrush is at least 4.

As further innovation of the present utility model, described column bottom support bracket is the SUS304 material.

As further innovation of the present utility model, described brush is silicon carbide material.

As further innovation of the present utility model, the granularity of the silicon carbide material of described brush is No. 800.

As further innovation of the present utility model, the bristle of described brush is fixed by glue.

As further innovation of the present utility model, described rolling disc is aluminum alloy material.

The beneficial effects of the utility model are:

. replace traditional emery wheel by hairbrush polysilicon is carried out to chamfer machining, polysilicon edge surface after the abrasive machine chamfering has angle burr to collapse limit crack or other defect is even arranged, edge surface is more coarse, in order to increase the qualification rate of the rear silicon chip of section, reduce the chamfering place and collapse limit, bright spot, and silicon rod chamfering place edge crack, will will use again the hairbrush polishing after its grinding wheel chamfering, and improve line with this and cut the qualification rate of producing section and reduce operating cost.

2. the mode that bottom support bracket is connected with rolling disc, facilitated the maintenance in the later stage of equipment, wearing and tearing, precision reduction that the regular dismounting of rolling disc and power transmission shaft causes have been reduced, further provide cost savings, hairbrush adopts the rigid metal piece to be connected with rolling disc, reduce the probability that hairbrush damages, reduced the cost of bristle simultaneously.

3. by processing through hole on rolling disc, hairbrush is installed, has been facilitated the dismounting of hairbrush.

4. by the rotation of a plurality of brush heads, polysilicon is carried out to polishing, provide cost savings, facilitate the single replacement of brush and maintenance simultaneously, also be convenient to draining of chip that processing produces, and accumulation that can globality is on brush, the quality of impact processing.

5. hairbrush employing customized SUS304 material, there is high corrosion resistance, under low temperature, room temperature and high temperature, all have higher moulding to return and toughness, and cold forming and weldability preferably, greatly provided the service life of hairbrush, also reduced the cost of manufacture of hairbrush base simultaneously.

6. adopt the hairbrush of the silicon carbide material of No. 800, there is good thermal conductivity, effectively prevent in polishing process the damage that excess Temperature causes polysilicon, silicon carbide material has good chemical resistance simultaneously, can adapt to complicated working environment, the hairbrush of silicon carbide material also has longer service life, can effectively reduce the cost of processing.

7. hairbrush is fixed by glue, prevents hairbrush scattering in process, affects crudy.

8. rolling disc adopts aluminum alloy material, and both durable have a rust-resisting property, also has good machining property simultaneously.

The schematic diagram of the hairbrush that Fig. 2 is the utility model polysilicon C angle hairbrush polisher.

In figure: 1. bottom support bracket, 2. brush, 3. hairbrush installing hole, 4. turning cylinder installing hole, the 5. diameter of rolling disc, L. brush.

The specific embodiment

As shown Fig. 1 and Fig. 2, the utility model is transformed for traditional polysilicon chamfering sander, in the V-shaped groove of sander, adopt the banister brush rubbing head to be replaced the abrasive disc of original abrasive machine, polishing head of the present utility model divides and comprises rolling disc 5 and be arranged on six hairbrush on rolling disc, hairbrush is installed on rolling disc 5 by six hairbrush installing holes 3, hairbrush comprises bottom support bracket 1 and 2 two parts of brush, six hairbrush installing holes 3 are arranged with respect to turning cylinder installing hole 4 annular arrays of rolling disc 5 central parts, it is that No. 800 carbofrax materials are made and made hairbrush have good chemical resistance and thermal diffusivity that hairbrush in the utility model is chosen granularity, the diameter of bristle is by glue, to be cured between 0.7mm and bristle, to guarantee the stability of hairbrush work, the bottom support bracket 1 of hairbrush adopts the SUS304 steel to make, there is good thermal diffusivity and stability, the diameter of hairbrush is L, the stability of hairbrush while adopting special technique to carry out bonding connection with assurance work between the brush 2 of hairbrush and bottom support bracket 1, hairbrush installing hole 3 interference fit of bottom support bracket 1 and rolling disc 5, than screw thread, the stability of hairbrush when this fit system can guarantee to rotate, replace by banister brush of the present utility model the polishing that original emery wheel carries out polysilicon C angle, having eliminated angle burr that pressure that original hard grinding wheel produces polysilicon in when polishing destroys the edge surface caused collapses limit crack or other defect is even arranged, the problems such as edge surface is more coarse, can make product percent of pass improve percent 0.5 percentage points, there is good social benefit.
