Abstract
The invention discloses a brushing and grinding device for surfaces of metal strips and particularly copper alloy strips with T-shaped sections. An oxide layer at the junction of thick and thin materials is difficult to brush clearly in the process of brushing, grinding and polishing the surfaces of the copper alloy strips with the T-shaped sections. Therefore, the invention provides a brushing and grinding device which has a simple structure, can brush and grind the surfaces of the strips and polish the oxide layer at the junction of the thick and thin materials, namely paired sand wheels run stably due to an eccentric structure, the contact pressure of the sand wheels and the strips is controlled to be stable by a method for controlling the current of a brushing motor to ensure that the surfaces of the strips are brushed, ground and polished uniformly, and side pressure is formed among non-woven fabrics which contact the surfaces of the strips and have abrasives by pressing plates arranged on both sides of the sand wheels, so that the oxide layer at the junction of the thick and thin materials is polished stably.
Description
Technical field
The present invention relates to a kind of sheet metal strip continuous cleaning lapping device, relate in particular to a kind of continuous cleaning lapping device of T section copper alloy band.
Background technology
The T section copper alloy band is the stock of special-shaped lead frame semiconductor discrete device, in the manufacture process in order to satisfy high velocity ram machine and packaging technology and to electroplate requirement, except material, dimensional tolerance, hardness and plate shape and uniformity are had the special requirement, surface roughness to band has very strict requirement, copper is a kind of metal of easy oxidation, the surface tends to produce oxide layer in the production process, therefore need carry out continuous cleaning to band grinds, Fig. 5 is original grinding wheel structure, has following problem:
Tend to make the hole to depart from the center when (1) the emery wheel hole is according to grinding wheel spindle reaming again and produce emery wheel and shake.
(2) because of T section band thickness material intersection is almost 90 degree, it is unclean to see that a among Fig. 4, b place usually clean with water.
In addition emery wheel in use with the pressure of the binding face of band since grinding wheel diameter diminish that to be difficult to continuous maintenance even.It is poor that above problem causes band to clean grinding back polishing effect with water, usually causes scrapping of later process product.
Summary of the invention
Purpose of the present invention is exactly a kind of device that is used for the grinding of T section copper alloy band continuous cleaning that provides for the weak point that overcomes above-mentioned prior art existence.Purpose of the present invention can be achieved through the following technical solutions:
Clean lapping device with water, it comprises a pair of on vertical plane to see Fig. 1～Fig. 3, the emery wheel of Bu Zhiing up and down, described emery wheel is made of the abrasive particle nonwoven, cantilever is fixed on the grinding wheel spindle, described grinding wheel spindle is fixed in the eccentric tube with rolling bearing, the other end of axle with clean motor shaft with water and be connected, described eccentric tube be have certain offset hollow shaft its fix with support by rolling bearing and up and down off-centre relative on lower grinding wheel center line symmetric arrangement, promptly going up the lower grinding wheel center line is exactly the center line of band at length direction, described eccentric tube is connected with flange, the other end of flange with clean motor with water and be connected, described worm gear is fixed on the eccentric tube, what described gear was paired is fixed on the eccentric tube, thereby driving worm gear when described worm screw is rotated rotates and two eccentric tubes is rotated simultaneously finish emery wheel and carry on or depress, depressing by the emery wheel depress control system of last lower grinding wheel realizes, it is by to cleaning the mensuration of current of electric with water, veer away greatly through becoming, upload to central controller PLC with the communication digital form, carrying out the PID computing after relatively with current setting value controls hold-down transmission device again and drives worm screw, worm gear realizes that the dynamic adjustment of drafts keeps evenly the pressure of the binding face of emery wheel and band, be provided with brake block at two eccentric tube middle parts in addition, push down two eccentric tubes under the effect of brake block at hydraulic cylinder and can effectively alleviate the equipment vibrations like this when the emery wheel position is not adjusted, hydraulic cylinder is return to make under the control of emery wheel depress control system and is thrown off two eccentric tubes under the effect of brake block at spring force when the emery wheel position is adjusted.
Fig. 6, Fig. 7 is improved grinding wheel structure, described emery wheel is by the abrasive material nonwoven, the emery wheel core, pressing plate, screw rod, form with nut, described abrasive material nonwoven is with resinoid bond tiny abrasive particle to be adhered to the space fabric construction that has that forms on the synthetic fibers to have resilience and stickiness preferably, because described pressing plate has two, locate by the groove on the emery wheel core, therefore centralized positioning is accurate, vibrations during the emery wheel rotation obviously alleviate, pressing plate will be clipped in the middle and size H1 is made less than the H size between the abrasive material nonwoven of this part with screw rod and nut and form bigger lateral pressure with the abrasive material nonwoven, thus the oxide layer of stable polishing thickness material intersection.
This is invented compared with prior art, and useful effect is:
1, device structure is simple and practical.
2, improved the surface quality of band.
3, minimizing is scrapped, and improves the yield rate of product.
