Description

Automatic equipment for cut working surfaces of a glass plate material and the controlling method the same}

The present invention relates to an automatic device for automatically grinding and managing a chamfer of a thin glass workpiece for display based on the drawn data, and a control method thereof, and more specifically, to a shape desired by a customer for a thin glass workpiece. The present invention relates to an automated apparatus and a control method for chamfering grinding of thin glass workpieces that can be automatically produced without the production and finally increase the stability of production and reduce the production cost.

In particular, the present invention relates not only to glass processing processes, but also to an automated apparatus for controlling the shape of a sheet glass workpiece for display that can be applied to conventional plastic products and similar flat products, and a control method thereof.

With the development of the industry, the development of personal portable IT devices such as mobile phones, PMPs, and MP3s has become indispensable for modern life, and the production quantity is increasing with the market demand.

Along with this trend, the characteristics of the front view window products, which are part of the components included in these personal portable IT devices, are also diversified, leading to a stronger and more functional part.

In response to these market demands, front sight glass is being replaced by glass or tempered glass products from plastic products. In addition, in flat panel displays (LCD, PDP, organic EL display, etc.), a specific shape product such as round or oval is required from consumers in the conventional rectangular form.

In general, in processing a glass to be processed to a specified shape, the contact area between the chamfering or chamfering tool and the glass workpiece is different according to the shape of the glass workpiece, it is difficult to expect a certain quality.

Chamfering processing refers to the process of cutting off blocks or plates made of angled or cornered metal, glass, etc., when the chamfering tool that rotates at high speed is in contact with the object. Chamfering tools in contact with the side of the glass workpiece is affected by manufacturing and installation errors, the vibration of the mechanical device itself, and will inevitably generate vibration by the rotation. Accordingly, there is a problem that the crack is generated or broken by the vibration of the chamfering tool due to the material characteristics of the glass workpiece.

On the other hand, in the processing tool of the glass workpiece, although it is possible to be chamfered or faced by laser processing, expensive production equipment must be provided and the productivity is low, which is not suitable for mass production.

In the process of processing into the shape having the inner diameter or the depression of the glass work, the contact with the material is wider and the interference is more and more, the wheel tool is actually rotated, and the method of contacting the glass sheet material is 5mm or more. Only the process of chamfering or chamfering the screen of the glass plate material for windows and windows which has a simple rectangular shape of thickness is performed.

As described above, in polishing a glass material, precision machining is difficult and in particular, in thin glass having a complicated shape having a depression or an inner diameter, it is more difficult to apply chamfering or chamfering. Therefore, transparent parts such as the screen display window of a mobile phone or the lens viewing window of a mobile phone camera are not easily broken and are replaced with plastics such as acrylic, which is easy to process. However, these acrylic materials are easily scratched by small impacts and frictions, which not only affects aesthetics but also hinders functionalities such as display performance or camera performance. This is going to be under control.

In the case of small electronic devices, simply replacing transparent parts with glass materials can improve aesthetics, display performance, and camera performance. Therefore, chamfering and polishing technology of small thin glass that is practically suitable for mass production is required.

Conventional chamfering (chamfering) processing technology corresponding to this is as follows.

At this time, the cam workpiece 108 is moved along the shape of the jig 104 while the cam CAM 108 moves along the shape of the jig 104. This consists of a movable structure.

As described above, the conventional chamfering plant factory manually supplies sheet work consisting of sheets to a work table, and the alignment before processing is to separately produce a tool having the same shape as a flat work piece, and replace it when the model is changed. It has a structure to use.

Such a conventional processing apparatus has a hassle for the operator to perform the alignment and supply of the flat plate work, and requires a wasteful operation that must continue to produce the tool according to the model changed during processing. In addition, in manufacturing the tool, there is a difficulty in producing a tool having a very high precision in order to produce a model within the tolerance range required by the customer.

Another conventional processing device is difficult to implement a highly precise alignment part, and implements a bypass method of performing the external shape machining and the external chamfering process together, which is an unreasonable method that takes the time of the external shape processing of a sheet-like plate processing As a result, productivity is inefficiently consumed.

The processing unit 210 having the above-described configuration automatically combines both X and Y axes based on the coordinate system of the X axis stage 282 and the Y axis feed mechanism 292 according to the control signal as programmed. To process the shape of the thin glass workpiece 200.

The working state of the present invention configured as described above will be described.

First, by pulling the stacking unit 222, which is the configuration of the automatic cell loader 202, by the operator to the front end of the main body 202, the multiple sheet glass workpiece 200 is simultaneously put into the loading guide (222a) The loading unit 222 is fixed so that the loading unit 222 is not separated.

When the size of the thin glass workpiece 200 loaded on the loading guide 222a is large or small, the width interval of the loading unit 222 set by adjusting the handle 238 is set to the width of the thin glass workpiece 200. Adjust to fit.

In this state, when the first servomotor 232 is driven according to a worker's work command, the first and second cylinders 228 and 230 alternately drive up. Accordingly, the thin glass workpiece 200 loaded on the loading guide 222a rises and waits at the pick-up position by the detection signal of the position sensor 234. At this time, the air blower 236 is driven and blown toward the loading unit 222 side, the stacked laminated glass workpiece 200 is not attached to each other without falling.

In this state, the workpiece transfer part 206 is driven to start the transfer operation of the thin glass workpiece 200. That is, the third cylinder 244 is operated by the drive signal of the second servomotor 250 to lower the picker 242 and the adsorption cylinder 242a of the picker 242 is mounted on the loading guide 222a. It will adsorb the thin glass workpiece 200 that was in the air. Subsequently, the picker 242 is raised by the lifting operation of the third cylinder 244, and the picker (248) is driven along the first LM guide 248 by driving the second servomotor 250 of the transfer unit 246. 242 moves to load the sheet glass workpiece 200 on the worktable 254 of the alignment unit 208.

In this case, the picker 242 picks up the laminated glass workpiece 200 loaded on the loading unit 222 and the series of operations for loading the worktable 254 of the alignment unit 208 are performed in the same manner, and thus repeated. The description of the process is omitted.

As described above, the automatic cell loader 204 and the workpiece transfer part 206 repeat the above-described series of operations until the stacked thin glass workpieces 200 are all loaded on the worktable 254 of the alignment unit.

In the process of picking up the thin glass workpiece 200 toward the alignment unit 208, the block box 258 of the alignment unit 208 is opened to load the thin glass workpiece 200 on the work table 254. The preparation operation is performed. That is, the liquid shutter 260 is in an open state, and the four alignment guides 256 provided on the blind spots of the work table 254 are in the open state from the work table 254.

In this state, when the picker 242 puts the thin glass workpiece 200 on the work table 254, four alignment guides 256 are uniformly narrowed to four corners of the thin glass workpiece 200. The sheet glass workpiece 200 is aligned with the center of the worktable 254 by being pushed in contact. In addition, the sheet glass work 200 is fixed on the work bench 254 by vacuum suction through a vacuum line formed on the work bench 254.

Since the sheet glass workpiece 200 is aligned and fixed to the center of the work table 254 by the operation of the alignment guide 256 in the above manner, regardless of the size and shape of the material, Even materials can be sorted. As shown in FIG. 8A, the thin glass workpiece 200 having a generally symmetrical structure can be aligned based on the center point as shown above. However, as shown in FIG. 8B, the asymmetric thin glass workpiece 200 is illustrated. When aligning, you can get better alignment result if you use the alignment method consisting of CAM and cylinder combination.

In particular, the alignment guide 256 of the alignment unit 208 is aligned using two angle adjusting screws 276 around the center pin 274 when the alignment block 272 contacts the sheet glass workpiece 200. The angle (theta axis) of the block 272 and the thin glass workpiece 200 is compensated for. In addition, the position of the four alignment blocks 272 composed of one workbench 254 as the center, the amount of deviation occurs during the processing of the thin glass workpiece 200, which is the alignment block 272 using the micrometer 278 To compensate for the position displacement.

When the fixing of the thin glass workpiece 200 on the worktable 254 is completed, the alignment operation of the alignment guide 256 is released to be opened to the original position. Subsequently, the fourth cylinder 258 is driven to lower the alignment guide 256 below the processing range, and the fifth cylinder 263 is driven to operate the liquid discharge shutter 260 to shield the opening of the block box 252. do. Accordingly, only the worktable 254 on which the thin glass workpiece 200 is fixed is exposed at the upper portion of the block box 252.

After that, the processing unit 210 located at the rear of the alignment unit 208 is operated to perform chamfering grinding processing. That is, while the X-axis stage 282 of the processing unit 210 moves in the X-axis direction, the Y-axis feed mechanism 292 provided at the bottom of the block box 252 of the alignment unit 208 is the center of the X- and Y-axes. Both axes are automatically combined and moved based on the coordinate system. When the chamfering grinding tool 284 is lowered by the driving of the third servomotor 290 and the rotary motor 288 is driven to rotate, the wheel 286 rotates, and the shape control system of the plate workpiece 200 is rotated. Chamfering grinding is performed according to the shape determined by the digitized shape in. In particular, as shown in Figs. 9A to 9C, the structure of the wheel 286 allows grinding of the edges, surfaces and holes of the thin glass workpiece 200.

At this time, since the third servomotor 290 is installed to each of the chamfering grinding tools 284, the wheel heights are set differently so that only the individual wheels can be repaired according to the wear amount of the wheels 286. do.

After the chamfering of the thin glass workpiece 200 is completed through the above-described process, the thin glass workpiece 200 is unloaded in the reverse order.

That is, when the chamfering grinding tool 284 is retracted after the chamfering grinding processing of the thin glass workpiece 200 is completed, the liquid release shutter 260 is opened and the alignment guide 256 is raised. Subsequently, the alignment guide 256 aligns the thin glass workpiece 200 fixed on the work table 254, and the picker 242 of the workpiece transfer part 206 picks up the finished thin glass workpiece 200 and freezes it. By sequentially loading the loading guide 222b is the discharge of the thin glass workpiece 200 is completed.

The step-by-step control of the present invention described below is performed by a sensor attached to each device unit and a control signal of a control unit controlling the driving of the devices.

As shown in the figure, a plurality of display glass plate 200 for display is loaded at the same time (S21). Then, the thin glass workpiece 200 is put into the cell loader 204, which is an automatic feeder, and then placed on the alignment unit 208 (S22 and S23). When the thin glass workpiece 200 is seated on the alignment unit 208, the alignment unit 208 moves up and down by aligning and absorbing the workpiece while performing the lifting operation (UP-DOWN), and then transferring the workpiece 210 to the processing unit 210. (S24, S25).

Next, when the thin glass workpiece 200 is located in the processing unit 210, the rotary motor 288 of the chamfering grinding tool 284 is to rotate at high speed (S26). At this time, the rotary motor 288 is transferred in the X-axis direction according to the X, Y coordinates according to the processing shape, the alignment portion is transferred in the Y-axis direction by the Y-axis transfer mechanism 292, the chamfered portion of the thin glass workpiece 200 Grinding is performed (S27, S28)).
