Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a polishing device for flattening the surface of a glass substrate, and particularly to a continuous polishing device for continuously grinding a plurality of continuous loads. Glass plate. [Prior technology] When the surface of a generally known glass plate or substrate is ground, the glass plate is placed on one of the upper surface or the lower surface plate that can be moved linearly and reciprocally, and the upper surface of one of the lower surface plates is rotated. Therefore, one surface or both surfaces of the upper glass plate and the lower glass plate can be polished. For example, in the conventional technique of continuously polishing the surface of a glass plate, a device for continuously polishing the surface of a glass plate includes: a polishing table for conveying the glass plate in one direction; and a plurality of polishing tools along the above The glass plate transfer direction of the polishing table is set. The polishing tool is arranged to withstand the eccentric rotation of the glass substrate with an eccentric axis, and to reverse the rotation phase of one of the polishing tools (as shown in jp — A — 2 — 83 1 50). In addition, the device for a polishing method and the use of a roll-shaped polishing pad are polishing tools conventionally known as polishing a plate-shaped body. Moving a plate-shaped body ', such as a glass plate, causes the surface of the plate-shaped body to move on the same plane. When a plurality of roll-shaped grinding cymbals are arranged, the axis thereof is parallel to the surface of the plate-shaped body, and is arranged in a direction substantially perpendicular to the moving direction of the plate-shaped body. Adjacent roll grinding 塾 are rotated in opposite directions to each other and pressed against the plate-shaped body to polish the surface of the plate-shaped body. The above-mentioned conventional techniques are disclosed in jp —A —2-8315〇 and

Description of the invention (8) ---- ~~ The supporting frame 9 and the moving rail 7 are bent into an arch shape so that the sliding platform 10 can pass through so as to form an endless loop, as shown in Figure 4, Increase the sliding △ by 1 〇 to move cyclically. The σ wooden track support frame 9, the moving rail 7, and the transfer holder 8 are cut off at two intermediate portions of the support holder 9 and the holder 7. The two moving rails 7 for transporting the sliding platform are suspended and supported on the upper surface plate 18, and are arranged on a mobile supporting frame. The moving supporting frame 33 is interrupted by the rail supporting frame 9 inserted into each space part. y As shown in FIG. 2, one side surface of the moving support frame 33 is provided at the—the closing frame 36 and a shaft 35 and pivoted on a support column 34 so as to be rotatable. A rod 37 has a balancer 40 connected to one of the tilting cylinders 39 at one end. The tilting cylinder 39 is adjacent to the support column 34 and includes a tilting frame 32. When one of the levers 38 of the tilt cylinder 39 moves vertically, the boom 37 rotates with the second halfway arrow. § When the moving support frame 3 3 is inclined, the upper surface plate 丨 8 is suspended by the sliding table 1-0 from the moving handle 7 and inclined at a height. Among them, the tilting device & is tilted as shown in FIG. 4. Next, the operation mode of the present invention will be described. The slide table 10 is stopped to hold the glass plate 16 and the pressure plate 17 is positioned at the moving support frame 33. The slide table 10 is then moved to the position of the conveying frame and reversed by the conveying motor 19 and inserted into A preset position. Next, the cylinder 20 provided on the conveyor 21 is activated to extend the cylinder 2 thereof. When the cylinder rod enters the receiver 丨 丨 of the sliding table 10, it is coupled to the transmission frame 21. When the conveying motor 19 rotates forward, the conveying frame 21 and the slide table 10 move forward to a preset position rotated above the grinding plate 3 on the polishing table 4, and

The compound plate 2 6 is driven down the line, then hold it and press it together. The glass 1 7 descends and rotates with the polishing liquid and moves downwards. When the above table 1 6 is fixed with a front and rear rotation, the cylinder 2 8 and the return plate 3 are separated. Next, the next conveying movement is performed when the upper part of the slide 16 is returned to the stopped position with the cylinder 20 next to it. The conveying rack 21 and the slide table conveying motor 19 rotate in the opposite direction. The conveying rack 21 is retracted along the conveying rail 8 ^ Stop at a preset position and stay to protect the sliding platform 丨 〇S. The upper surface plate 18 is suspended from the sliding second panel 18 stopped on the grinding disc 3 according to the level set on the upper beam 22 toward @ 复 装 〇 置 First, when the horizontal reciprocating motor 30 rotates forward and backward, the water The guide rail 25 moves back and forth, and the cylinder rod of the compression cylinder 28 is connected to the upper end of the shaft portion 13 toward the end of the cylinder rod = the shaft portion 13 supported by the spring 15. When the support is aligned with the shaft portion 13; When the pressure plate 17 of the glass plate 16 moves back and forth horizontally, if the grinding plate 3 moved by the pressure plate contacts and applies pressure, the surface of the glass plate 16 and the grinding plate 3 with a liquid film rotate and polish, It also reciprocates, and the surface plate 18 applies pressure. The face plate 18 applies pressure to the rotating grinding disc 3, polishes time, and the upper surface plate 18 moves horizontally to and fro with the horizontal reciprocating motor 30, and the upper surface plate 18 is stopped due to the compression position and the stop of the horizontal reciprocating motor 30. Ascend and grind the reverse H stage 10 and pause on the moving handle 7 and wait on the conveying rail 8 Ϊ When the conveying motor 19 rotates, the sliding stage 10 and the conveying wood 2 1 move forward again. Table: UM: No, the next horizontal reciprocating device is next. ^ The next grinding disc 3 is set on the lower part. Glass plate The next grinding disc 3 is polished, and the grinding disc 3 is steamed red 2200412275

The reciprocating operation is performed by the compression cylinder 28 and the horizontal reciprocating motor 30, so that the glass plate 16 is continuously polished by the parallel grinding discs 3. Behind this process line, the side 'glass plate 16 is held on the upper surface plate i 8 suspended by a sliding stage 丨 〇 and the glass plate 16 is continuously repeatedly polished and conveyed. Therefore, the plurality of upper surface plates 18 are continuously polished until completion.

After passing through the plurality of grinding discs 3 and completing the polishing process, the slide table 10 located in a suspension area of the mobile support frame 33 is automatically or manually moved forward to the moving handle 7 'of the mobile support frame 33. When the sliding table 10 is suspended on the moving support frame 33 ', if the tilting cylinder 39 of the tilting device 32 is actuated, one of the tilting cylinders 39 = 38 descends, and the arm 37 and the shaft 35 rotate about an axis, and the support frame 33 is moved It is arranged on one end of the arm 37 and then rotates, and the surface plate 18 arranged on the moving handle 7 'through the sliding table 10 also moves accordingly. Therefore, the glass plate 16 adhered to the pressure plate 17 on the top plate 18 also forms an inclined state, and displays the surface condition for the operator to see.

§ When the above status is maintained, the glass plate 16 in the polished state is removed and replaced with a new glass plate. Further, when the tilting cylinder 39 is returned, the terminal of the moving support frame 33 is brought closer to the terminal of the holding support frame 9 to become a straight line. The surface plate 18 suspended on the sliding table 10 is manually moved to a predetermined position on the moving handle 7 and waits for coupling with the conveying rack 2 at a preset position. After coupling with the conveying rack 21, Repeat the above action. On the right, a plurality of sliding stages 10 with appropriate intervals are arranged on the moving rail 7 at intervals, and other processing plates are used instead of the upper surface plate 18 to clean the load on the disc 3. The grinding disc 3 can be simultaneously Appropriate cleaning is obtained during manufacture, making the grinding quality more stable.
