Description

Cutter wheel cleaning mechanism and scribing device

The invention relates to a cutter wheel cleaning mechanism and a scoring device. The cutter wheel cleaning mechanism is installed in a scoring device for scoring lines for processing and breaking a resin substrate or a brittle material substrate using a cutter wheel, and the cleaning is removed and attached to the knife The dust of the wheel.

Generally, in the case of cutting a unit substrate from a large mother substrate, for example, a scribing device as shown in Patent Document 1 is used to move the cutter wheel while pressing the cutter wheel against the surface of the mother substrate to form a longitudinal shape in a lattice shape. Lateral scribing lines (cutting grooves), and then, operations such as bending the substrate are performed to break from the scribing lines, thereby taking out the unit substrate.

When the longitudinal and lateral scoring lines are processed on the mother substrate, the cutter wheel is continuously used, so the dust or whisker-like cutting chips present in use adhere to the tip of the cutter wheel or enter the gap between the holder holding the cutter wheel Happening. In particular, since the resin substrate has many cutting chips and is sticky, adhesion to the blade tip or gap is likely to occur. [Prior Technical Literature] [Patent Literature]

[Problems to be solved by the invention]

If dust or cutting debris adheres to the tip of the cutter wheel or the gap with the holder, the rotation of the cutter wheel becomes worse, the machining accuracy of the scribing line becomes worse, and the load on the cutter tip increases, and the life of the cutter tip shortens. Therefore, the tool tip is inspected every time it is used, and if there is adhesion of dust or the like, it is necessary to use a brush or the like to clean it manually, but this operation is very troublesome and time-consuming.

Therefore, in view of the above-mentioned problems, an object of the present invention is to provide a cutter wheel cleaning mechanism of a scoring device, which can cleanly remove dust attached to the cutter wheel in a short time without using manual work. [Means to solve the problem]

In order to achieve the above object, the following technical means are adopted in the present invention. That is, the present invention is a cutter wheel cleaning mechanism that is mounted on a scoring device that processes a scribe line by moving the cutter wheel while pressing the cutter wheel against the surface of the substrate. The cutter wheel cleaning mechanism is configured to include : Motor-driven rotating brush, which is located away from the working area for processing the scoring line and arranged within the movable range of the cutter wheel; and a suction port, which is opened near the rotating brush, and the suction port is connected For air source. The present invention also targets a scoring device equipped with the above-described cutter wheel cleaning mechanism. [Effect of invention]

According to the present invention, by moving the cutter wheel to the position of the rotating brush as needed, the rotating brush can be used to cleanly remove the dust or cutting debris attached to the tip of the cutter wheel or the gap with the holder in a short time and can be eliminated The complexity caused by manual work as in the past, and because the removed dust is attracted from the suction port, it is possible to avoid pollution around the cutter wheel. In addition, when the scribing process is performed by the cutter wheel, since the cleaning mechanism is located away from the work area, there is an effect that the scribing work is not hindered.

In the present invention, it is preferable that the suction port is connected to an air suction port of a vacuum ejector via a pipe, and an air source is connected to the air inflow port of the vacuum ejector via a duct to drive the motor of the rotating brush Formed by an air motor. In this way, the compressed air from the air source can be used to perform the dust suction operation at the suction port, and the air source of the suction port and the air source of the rotating brush can share the same one, so that the labor saving of the mechanism can be achieved.

In addition, in the present invention, it is preferable that the rotating brush and the suction port are assembled together with the vacuum ejector as a unit on a common bottom plate. Thereby, the cleaning mechanism can be closely concentrated, and it is easy to assemble to the scribing device.

Hereinafter, the details of the cutter wheel cleaning mechanism of the present invention will be described in detail based on FIGS. 1 to 5. FIG. 1 is a front view showing an embodiment in which the cutter wheel cleaning mechanism A of the present invention is assembled into a general scribing device. The scoring device includes: a platform 1, which holds the substrate W to be processed on the upper surface; a rotating mechanism 2, which rotates the platform 1 on a horizontal plane; a track 3, which holds the platform 1 and the rotating mechanism 2 It is held in such a way that it can move in one direction (the front and back directions in FIG. 1); the screw shaft 4, which is used to move the platform 1 along the rail 3; and the motor 5, which drives the screw shaft.

In addition, the door frame 6 installed across the platform 1 is provided with a horizontal beam 7 extending in a direction orthogonal to the moving direction of the platform 1, and the horizontal guide 8 provided on the beam 7 can be The mounting plate 10 provided with the scoring head 9 is movably held. A cutter wheel 12 is attached to the lower end of the scoring head 9 via a holder 11. In addition, the scoring head 9 is assembled so as to be movable up and down relative to the mounting plate 10. Thereby, a structure is achieved in which the substrate W is placed on the stage 1 and the cutter wheel 12 is moved along the guide 8 while pressing the cutter wheel 12 against the surface of the substrate, so that a scribe line can be processed on the surface of the substrate.

In the scoring device, a cutter wheel cleaning mechanism A is provided within a range where the cutter wheel 12 can be moved along the guide 8 at a position away from the working area for processing the scribe line, that is, a position away from the platform 1.

As shown in FIG. 2, the cutter wheel cleaning mechanism A includes a rotary brush 13 and a pair of suction ports 14 that are opened near the rotary brush 13. The suction port 14 opens toward the rotating brush from left to right in the circumferential direction of the rotating brush 13. In addition, the rotary brush 13 includes an air motor 15 as a driving source, and is formed to introduce and drive compressed air from an air source such as a compressor through the duct 16 from the air inlet 17. The introduced air is discharged from the exhaust port 18.

In addition, as shown in the air circuit diagram of FIG. 4, the suction port 14 opening toward the rotating brush 13 is also connected to the suction port 20 a of the vacuum ejector 20 through the pipe 19. The air inflow port 20b of the vacuum ejector 20 is connected to an air source P such as a compressor via a duct 21. An air flow controller 23 is provided at the air inflow port 20b of the vacuum ejector. In this embodiment, the air source P connected to the vacuum ejector 20 and the air source of the air motor 15 share the same one. However, the air source can also be formed separately.

The vacuum ejector 20 is a well-known one that is generally widely used, so its detailed description is omitted, but as shown generally in FIG. 3, it is configured as follows: the compressed air flowing in from the air inflow port 20b is concentrated by the nozzle 20c and diffuses at high speed The chamber 20d jets and is released from the discharge port 20e. The surrounding air is introduced by a high-speed jet toward the diffusion chamber 20d, and the diffusion chamber 20d is decompressed, and an attractive force is generated in the suction port 20a connected to the diffusion chamber 20d.

The rotating brush 13 or the suction port 14 opening toward it and the vacuum ejector 20 or the piping 19 are assembled on a common bottom plate 22 and formed as a unit. As shown in FIG. 1, the bottom plate 22 is mounted on the frame 6 of the scoring device via the mounting corner 24 in an adjustable mounting position.

In the above configuration, when the scoring process is performed by the cutter wheel 12, the cutter wheel cleaning mechanism A is located at a position away from the platform 1 that becomes the work area, so the scoring work is not hindered. When cleaning the cutter wheel 12, as shown in FIG. 5, by moving the cutter wheel 12 along the guide 8 to the position of the rotary brush 13 of the cutter wheel cleaning mechanism A, the rotary brush 13 is used to align the cutter wheel 12 or the holder The clearance part of 11 can be cleaned to remove dust or cutting debris attached to the tip or clearance of the knife in a short time. The removed dust is sucked from the suction port 14 and discharged from the discharge port 20e of the vacuum ejector 20. In the figure, the discharge port 20e is left in an exposed state, but it is preferable to connect the discharge port (not shown) connected to the outside of the scoring device to discharge the dust to the outside of the device or to another Set dust box.

In addition, the above-mentioned cleaning operation of the cutter wheel by the rotating brush is preferably performed periodically every time a certain time is scored. In this way, the sharpness of the cutter wheel can be maintained, the score line can be processed with high precision, and the service life can be extended.

The representative embodiments of the present invention have been described above, but the present invention is not necessarily limited to the above embodiments. For example, the scoring device for assembling the cutter wheel cleaning mechanism of the present invention is not limited to the configuration shown in the above embodiment, and the entire scoring device having a structure capable of processing scoring lines with the cutter wheel can be targeted. In addition, the driving source of the rotary brush may be an electric motor instead of a pneumatic motor. In addition, the present invention can be appropriately modified or modified within the scope not departing from the scope of the patent application. [Industry availability]
