Description

The position detecting mechanism of using in a kind of glass grinder

Technical field

The utility model belongs to glass deep process technology field, relates to glass grinder and glass safety angle is carried out to the attendant equipment of using in manufacturing procedure, the glass position testing agency using in glass grinder specifically.

Background technology

Existing plate glass adds man-hour on double-edge grinder, must four safety angle of grinding, and these four angles generally require in the same size.This stock removal that will ensure in every a collection of glass every and each angle is identical, ensure the identical glass position that just must detect exactly of stock removal.Be generally to adopt photoelectric switch or travel switch to detect now, it is large that photoelectric switch is disturbed by environmental factor, locates not accurate; Travel switch is easy to wear, is subject to contact Contact Effect, and accuracy of detection is not high yet.Therefore how improving better glass position accuracy of detection in grinding step is the key of problem.

Summary of the invention

The utility model, in order to address the above problem, has designed the position detecting mechanism of using in glass grinder, simple in structure, cost is low and glass position accuracy of detection is high, stable and reliable for performance.

The technical solution adopted in the utility model is: the position detecting mechanism of using in a kind of glass grinder, for the glass substrate to be processed that enters ground station is carried out to position probing, key is that structure comprises the mounting base that is fixed in grinder frame, is arranged at the swing arm on mounting base, the roller that is positioned at swing arm two ends and approach switch sensor block, swing arm Bringing-back mechanism and is fixed on the approach switch on mounting base by mount pad by rotating shaft, and approach switch is connected with PLC by signal connecting line.

The beneficial effects of the utility model are: 1, approach switch have advantages of duplicate detection precision high and not Shou Huan Base-on-environment affect, can solve better the problem that glass position accuracy of detection is low; 2, the utility model is simple in structure, cost is low, dependable performance.

Detailed description of the invention

The position detecting mechanism of using in a kind of glass grinder, for the glass substrate to be processed 13 that enters ground station is carried out to position probing, importantly structure comprises the mounting base 2 that is fixed in grinder frame, is arranged at the swing arm 4 on mounting base 2, the roller 3 that is positioned at swing arm 4 two ends and approach switch sensor block 8, swing arm Bringing-back mechanism and is fixed on the approach switch 12 on mounting base 2 by mount pad 9 by rotating shaft 6, and approach switch 12 is connected with PLC by signal connecting line.

Described swing arm Bringing-back mechanism comprise fork reset drives mechanism and be fixed on mount pad 9 for limiting the spacing mandril 10 of swing arm 4 anglecs of rotation.In the time that roller 3 is pushed down in glass substrate forward position, swing arm 4 is 6 left-hand revolutions around the shaft, approach switch 12 exceeds and detects distance with sensor block 8, at this moment approach switch 12 sends glass and puts signal in place to PLC, in the time that after glass substrate, edge departs from roller 3, swing arm 46 clickwises resetting by spacing mandril 10 around the shaft, at this moment approach switch 12 senses sensor block 8, approach switch 12 sends glass and leaves signal to PLC.Visible, can accurately realize the position probing to glass substrate by approach switch 12 and PLC, so that PLC controls the grinding accuracy of grinder to glass substrate safety angle better.

Reset better for the ease of swing arm 4, described fork reset drives mechanism comprises the magnet 7 being fixed in swing arm 4 and is fixed on the iron block 11 on mount pad 9 by strut bar 14, magnet 7 coordinates the auxiliary fork of formation to reset drive configuration with iron block 11.

The periphery of described mounting base 2 is also provided with waterproof 1.Waterproof plays waterproofing protection effect to whole position detecting mechanism.

In the swing arm 4 between roller 3 and rotating shaft 6, be also set with water bloking piece 5.Water bloking piece 5 plays dash effect, and anti-sealing is dirty in responding to fast 8 and the infringement that causes of magnet 7 along swing arm 4 effectively.

In the specific implementation, as shown in Figure 1, in the time that just the glass substrate to be processed 13 in grinding travels forward along direction shown in arrow, the top of roller 3 can be collided in the forward position of glass, swing arm 4 can 6 rotate counterclockwise around the shaft, when exceeding certain angle, sensor block 8 can depart from the induction range of approach switch 12, makes approach switch 12 produce a falling edge signal to PLC.In like manner, after glass is walked, after glass, edge departs from roller 3, swing arm 46 clockwise rotates reset around the shaft under eccentric Action of Gravity Field, better reset for the ease of swing arm 4, magnet 7 is set in swing arm 4, the iron block 11 of locating by strut bar 14 is set on mount pad 9, utilize magnet 7 and the adsorption affinity of iron block 11 that swing arm 4 is resetted; In the time that sensor block 8 reenters in the induction range of approach switch 12, approach switch 12 can produce positive rise signals to PLC.Spacing for the ease of swing arm 4, in the time that swing arm 4 turns to preset limit position, withstand by spacing mandril 10, at this moment magnet 7 can hold securely with iron block 11.In this process, PLC receives falling edge signal, controls corresponding grinding component glass is carried out to grinding, if PLC receives positive rise signal, controls corresponding grinding component and stops the grinding to glass.Visible, this position detecting mechanism can accurately be realized the position probing to glass substrate, controls better the grinding accuracy of grinder to glass substrate safety angle with PLC.
