Full-automatic crystal bar coarse grinding and accurate grinding combined surface grinding and chamfering integrated machine and crystal bar grinding unit

Abstract

The invention discloses a full-automatic crystal bar coarse grinding and accurate grinding combined surface grinding and chamfering integrated machine and a crystal bar grinding unit. The crystal bargrinding unit comprises a coarse grinding and accurate grinding head for grinding and chamfering four planes and four arcs and a grinding driving mechanism connected to the coarse grinding and accurate grinding head. The coarse grinding and accurate grinding head comprises a coarse grinding abrasion wheel head, an accurate grinding abrasion wheel head and a first driving motor. The coarse grindingabrasion wheel head and the accurate grinding abrasion wheel head are in power connection to a first driving motor through transmission shafts, separately. The accurate grinding abrasion wheel head driven by the transmission shaft thereof moves front and back relative to the coarse grinding abrasion wheel head. The full-automatic crystal bar coarse grinding and accurate grinding combined surfacegrinding and chamfering integrated machine integrates functions of four plane chamfering and coarse grinding and four chamfering and accurate grinding, dimension detection, crystal orientation detection and the like, is centralized in processing step, integrates a coarse grinding station and an accurate grinding station in a same station for grinding and chamfering four planes and four arcs, reduces the quantity of coarse and accurate grinding shafts of the equipment, is low in equipment cost, reduces the working allowance left by coarse grinding for accurate grinding, and reduces the quantityof accurate grinding processing cutters while reducing the loss of the crystal bars, so that the processing efficiency is improved and the equipment cost is lowered.

Description

technical field [0001] The invention relates to the technical field of single crystal ingot processing equipment in the photovoltaic industry, in particular to a fully automatic crystal ingot coarse and fine grinding combined surface grinding and chamfering integrated machine and ingot grinding unit. Background technique [0002] The grinding process of silicon wafers in the solar photovoltaic industry is a key process. The current grinding process mainly has the following problems: [0003] 1. At present, the mainstream of the grinding process for crystal ingot processing at home and abroad is two-sided rough grinding and two-sided fine grinding. The rough grinding and fine grinding are performed by two stations, so two sets of drive mechanisms and grinding wheel spindle systems are required, which results in The cost of equipment is high, and with the decline in profits of the photovoltaic industry, the industry's demand for reducing equipment costs is becoming increasingl...
