Embodiment 1

[0044] Embodiment one, such as Figure 5 As shown, taking the processing of the S136 light guide plate template as an example, the hardness after heat treatment is 50HRC, and the template size is 120*50*25mm. The specific processing steps are as follows:

[0045] Step 501 , using diluted weak acid to clean the surface of the light guide plate template.

[0046] Step 502 , adding a polyurethane soft polishing pad on the workbench, and making the light guide plate template and the soft polishing pad contact surface-to-surface under the condition that the clamping part clamps the light guide plate template.

[0047] Step 503, configure the processing load of the clamping part as 30kPa, the working parameters of the rotating speed of the clamping part and the workbench as 25rpm, and the processing time as 25min. During processing, the automatic liquid adding device adds abrasive solution and polishing liquid to the workbench, Based on this, the light guide plate template is proce...

Embodiment 2

[0051] Embodiment two, such as Image 6 As shown, taking the processing of the sus304 light guide plate template as an example, the hardness after heat treatment is 42HRC, and the template size is 200*140*0.8mm. The specific processing steps are as follows:

[0052] Step 601, using diluted weak acid to clean the surface of the light guide plate template.

[0053] Step 602 , installing a polyurethane soft polishing pad on the workbench, and making the light guide plate template and the soft polishing pad contact surface-to-surface under the condition that the light guide plate template is clamped by the clamping part.

[0054] Step 603, configure the processing load of the clamping part to be 35kPa, the rotation speed of the clamping part and the workbench to be 22rpm, the processing time to be 30min, and the automatic liquid feeding device to spray abrasives, polishing liquid and coolant to the workbench during processing , based on which the light guide plate template is pro...

Embodiment 3

[0057] Embodiment three, such as Figure 7 As shown, taking the processing of the S-STAR light guide plate template as an example, the hardness after heat treatment is 40HRC, and the template size is 100*40*25mm. The specific processing steps are as follows:

[0058] Step 701, using diluted weak acid to clean the surface of the light guide plate template.

[0059] Step 702 , installing a polyurethane soft polishing pad on the workbench, and making the light guide plate template and the soft polishing pad contact surface-to-surface under the condition that the clamping part clamps the light guide plate template.

[0060] Step 703, configure the working parameters of the processing load of the clamping part as 40kPa, the rotation speed of the workbench as 20rpm, and the processing time as 30min. During processing, the automatic liquid adding device adds abrasives and polishing liquid to the workbench, based on which the light guide plate Templates are processed.

Abstract

Disclosed is a device for processing a light guide plate template and a method for processing same, the processing device comprising a rotatable workbench (1), a polishing component (2) installed on the workbench (1) and a clamping component (3) for clamping the light guide plate template, wherein in the state of the light guide plate template being clamped by the clamping component (3), the rotating workbench (1) drives the polishing component (2) to polish a crater structure on the light guide plate template. The crater structure on the light guide plate template is removed by using the processing device for the light guide plate template, so that the retardation from which plastic particles suffer in a mould cavity during injection moulding is reduced, thus the mesh point formed by injection moulding is more saturated, and when releasing the mould, the phenomena of mould sticking, mould drawing and the like are reduced, such that the final dimension precision and mesh point precision of the light guide plate are improved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a processing device for a light guide plate template and a processing method thereof. Background technique [0002] At present, the main production method of the light guide plate is injection molding technology. The main method of this technology is: inject heated plastic fluid through the injection molding machine into the injection cavity of the light guide plate template, and the bottom surface of the injection cavity is provided with optical dots. After cooling into a solid state, the light guide plate is removed from the injection molding cavity. Since the quality of the light guide plate is mainly determined by the injection cavity inside the light guide plate template, the precision of the light guide plate template becomes an important factor affecting the size and precision of the light guide plate. [0003] The main structure that affects the accuracy of the lig...
