Description

Field of the invention

The present invention belongs to the field of automated devices, and more particularly relates to an automated apparatus for polishing a light guide plate.

State of the art

The functional principle of the light guide plate of a mobile phone screen comes from the liquid crystal display of a laptop. It is a high-tech product that converts a linear light source into a surface light source. Using an optical acrylic (PMMA) / PC as a substrate and the backlight module technology of an LCD display as well as a laptop and the high light conductivity of the light guide points, light of a light guide plate is refracted by computing the light guide points via a computer such that a surface light source becomes more uniform Light emission is formed. Thus, advantageously, an ultra-thin structure, high brightness, uniform light transmission, high energy efficiency, good environmental friendliness, avoidance of darker areas, long life, excellent fade resistance, easy and quick installation and maintenance are achieved.

Currently, individual light guide plates are obtained by cutting after an injection molding process, wherein individual light guide plates must be polished by means of a polishing machine. A light guide plate is a high-tech product that converts a linear light source into a surface light source. The evenness of the lateral sides and the surface of a light guide plate plays an important role in the conversion effect of a line light source and the brightness and softness of the light. When polishing a mobile phone light guide plate high demands are placed on the positioning accuracy of the light guide plate due to the high speed of the polishing motor of 20,000 revolutions per second. However, due to insufficient positioning accuracy of a prior art positioning device, the light guide plate is susceptible to undesired misalignment, so that accurate positioning is not possible and thus product quality is compromised.

For example, the positioning mechanism disclosed in the Chinese Patent "Positioning Mechanism, Conveyor With Such Positioning Mechanism, and Positioning Method" (US Pat. CN 101279679 B ), insufficient positioning accuracy and therefore should be improved.

Der dritte Schlitten wird durch die Schubstange des ersten Verschiebungs-Pneumatikzylinders derart geschoben, dass er entlang der dritten Gleitschiene gleitet und somit den ersten Positioniermechanismus in Bewegung zu der Tragplatte hin versetzt. Der vierte Schlitten wird durch die Schubstange des zweiten Verschiebungs-Pneumatikzylinders derart geschoben, dass er entlang der vierten Gleitschiene gleitet und somit den zweiten Positioniermechanismus in Bewegung zu der Tragplatte hin versetzt.

Hereinafter, the operation and the operation of the present invention will be explained (taking as an example a polishing operation of a mobile phone light guide panel):

• The mobile phone light guide plate is placed on the turntable and the support plate. Under control of a pre-set control system, the machine is put into operation. The third carriage is slid by the push rod of the first displacement pneumatic cylinder so as to slide along the third slide rail, thus displacing the first positioning mechanism in motion toward the support plate. The fourth carriage is pushed by the push rod of the second shift pneumatic cylinder so as to slide along the fourth slide rail, thus displacing the second positioning mechanism in motion toward the support plate. Thus, a positioning of the light guide plate is made possible. In addition, the light guide plate is sucked to the support plate by means of a negative pressure system, after which the first positioning mechanism and the second positioning mechanism arranged on the third processing side are reset and the positioning mechanism arranged on the third processing side displaces together with the third working platform. Thereafter, the third working platform shifts under drive from the X-axis driving mechanism to the polishing position, and under the driving of the polishing motor, the polishing blade polishes one working side of the light guiding plate, then under the influence of the X-axis driving mechanism, the Y-axis driving mechanism and the rotation drive mechanism rotates the light guide plate by 90 °, and thus sequentially polishing the second processing side and the third processing side of the light guide plate is made possible. During this process, the polishing device remains motionless and does not have to be moved or raised or lowered. Thereafter, the material removal mechanism shifts under the drive of the displacement drive mechanism along the X-axis. By means of Hubpneumatikzylinders the material removal assembly is driven for displacement up and down and by means of the Schwenkpneumatikzylinders for rotation to allow removal of material. Thus, a fully automatic and intelligent polishing of the mobile phone light guide plate is achieved.

In this case, the positioning of the positioning takes place such that after placing a Mobilfunklichtleitplatte and driving on the first displacement pneumatic cylinder and the second displacement pneumatic cylinder, the position of the first positioning mechanism is roughly adjusted relative to the machine by means of the first base support, after which the positioning rod by passing a bolt is fixed by the threaded hole of the first attachment piece and tightening the first attachment piece. Subsequently, the first attachment piece and the first carriage are pushed by turning a knob of the micrometer so that they slide along the first slide rail and thus move the positioning rod in motion toward the workpiece, via the tension spring, the first attachment piece and the first carriage after moved back and thus the positioning rod is displaced in motion away from the workpiece. Thereafter, the position of the second positioning mechanism relative to the machine is roughly adjusted. By turning the fine adjustment nut, the second attachment piece and the second carriage are pushed so that they move along the second slide rail and thus move the positioning piece and the positioning bearing in motion towards the workpiece. Now, the outer ring of the positioning bearing abuts on a lateral side of the workpiece and the Begrenzungsausbuchtung extends to the upper surface of the Workpiece. By rotating the positioning bearing, the sliding friction between the first positioning mechanism and the workpiece is converted into rolling friction, thus reducing the frictional force. Thus, accurate positioning of two opposing lateral sides of the workpiece is enabled by means of a reference positioning mechanism and a buffering compensation positioning mechanism.

In the foregoing, only one embodiment of the present invention has been explained without limiting the scope of the invention. Any equivalent structure provided by the contents of the specification and the accompanying drawings or directly or indirectly applicable to other relevant arts also falls within the scope of the present invention.
