Description

Technical Field

[0001] The invention relates to the technical field of glass substrate processing equipment, and in particular to a harpoon type grinding workbench for a glass substrate. Background Art

[0002] Liquid crystal substrates usually refer to high-precision, high-performance substrate materials used in semiconductors, display panels, optoelectronics and other fields. With the continuous development of electronic technology, high-generation substrates are widely used in various electronic products, including liquid crystal display panels and organic light-emitting diode panels.

[0003] In the production process of liquid crystal substrates, the grinding process mainly involves deep grinding of the edges of the substrates. At present, when grinding high-generation substrates, the substrates are first transported to the grinding turntable. After the long and short sides are ground and the substrate direction is changed and centered, the substrate is transferred to the bottom of the grinding mechanism by a robot arm, and the substrate is positioned. The edge of the substrate is ground by the grinding mechanism. After the grinding of one side of the substrate is completed, the substrate is transferred to the turntable by a robot arm. After the substrate direction is changed and centered, the substrate is transferred to the bottom of the grinding mechanism by a robot arm for grinding. The overall grinding process of the four sides of the substrate is relatively cumbersome, thereby extending the processing time and reducing the processing efficiency.

[0035] Embodiment 1

[0036] In order to solve the technical problems in the background technology, a glass substrate harpoon grinding workbench is provided as follows:

A vacuum suction cup 15 is fixedly installed, a ventilation cavity 131 is opened in the support rod 13, a connecting pipe 132 connected to the ventilation cavity 131 is fixedly installed at one end of the support rod 13, the other end of the connecting pipe 132 is connected to the vacuum suction cup 15, and a connecting pipe 133 connected to the ventilation cavity 131 is fixedly installed at the other end of the support rod 13, the other end of the connecting pipe 133 is connected to the vacuum box 121 and extends to the inside of the vacuum box 121, and a solenoid valve 134 is fixedly installed on one end of the connecting pipe 133 extending to the inside of the vacuum box 121, and a pump box 16 connected to the inside of the vacuum box 121 is fixedly installed on the frame 1. It is worth mentioning that a negative pressure pump is arranged in the pump box 16, and substrates are placed on the tops of the multiple support rods 13 of the two groups of support units;

[0038] A slide groove 135 is provided on one side of the support rod 13 along the direction of the connecting plate 14, and a mounting block 2 is slidably mounted in the slide groove 135 on one side of the support rod 13 through an electric slider, and a limiting member 21 is installed on the top of the mounting block 2, and the limiting member 21 extends to the top of the support rod 13. Through multiple groups of limiting members 21, a substrate placed on multiple support rods 13 is limited, so that the substrate is placed centrally on the multiple support rods 13;

[0039] A mounting frame 3 sleeved on top of the two frames 1 is installed on the outer side of the two frames 1, a horizontal slide rail 31 is fixedly installed on the inner top wall of the mounting frame 3 and located just above the two frames 1, a sliding block 32 is slidably installed at the bottom of the slide rail 31, an electromagnetic slider 33 connected to the sliding block 32 is fixedly installed on the slide rail 31, a horizontal slide rail 2 34 is fixedly installed at the bottom of the sliding block 32, a sliding block 2 35 is slidably installed at the bottom of the slide rail 2 34, an electromagnetic slider 2 36 connected to the sliding block 2 35 is fixedly installed on the slide rail 2 34, a grinding mechanism 4 is installed at the bottom of the sliding block 2 35, which is used to grind the edge of the substrate placed on the multiple support rods 13, and a rotating and translating mechanism 5 is installed on the mounting frame 3, which is used to rotate or translate the substrate placed on the multiple support rods 13.

[0040] When grinding the edge of the substrate, the substrate is transported to the multiple support rods 13 of the two groups of support units, and the two sides of the substrate are respectively located between two adjacent support rods 13. At this time, the substrate contacts the multiple vacuum suction cups 15 at the ends of the multiple support rods 13, and the mounting block 2 is simultaneously displaced toward the substrate along the slide groove 135 through the multiple electric sliders located on both sides of the substrate. When the mounting block 2 moves, it can drive the multiple limiting members 21 to move so as to contact the substrate. When the limiting members 21 located on both sides of the substrate are in contact with the substrate, the substrate placed on the multiple support rods 13 can be limited. The substrate is placed centrally on a plurality of support rods 13. At this time, the solenoid valve 134 connected to the ventilation cavity 131 in the support rod 13 in contact with the substrate in the vacuum box 121 is controlled to be opened, and the other solenoid valves 134 are closed. Then, the negative pressure pump in the pump box 16 is controlled to be turned on to pump out the air in the vacuum box 121, so that negative pressure is formed in the vacuum box 121. The air at the plurality of vacuum suction cups 15 flows into the vacuum box 121 through the ventilation cavities 131 in the plurality of support rods 13, so that the plurality of vacuum suction cups 15 can perform negative pressure positioning on the substrate. At this time, the electromagnetic slider 33 is used to make the sliding block 32 move in the vacuum box 121. The bottom of the slide rail 1 31 slides, so that the grinding mechanism 4 is displaced to between the two support rods 13 and in contact with the edge of the substrate, and then the sliding block 2 35 is displaced at the bottom of the slide rail 2 34 by the electromagnetic slider 2 36, driving the grinding mechanism 4 to displace between the two support rods 13, so as to realize the grinding of the edge of the substrate. After the grinding between the two support rods 13 and the edge of the substrate is completed, the electromagnetic slider 1 33 and the electromagnetic slider 2 36 can be used to grind the edge on the opposite side after the grinding is completed. After the grinding of both sides of the substrate located between the two adjacent support rods 13 is completed, the control pump box 16 is The negative pressure pump is turned off, the negative pressure positioning of the substrate is canceled, the substrate is rotated by the rotation and translation mechanism 5, and with the cooperation of the rotation and translation mechanism 5 for translating the substrate, the other two sides of the substrate are respectively located between two adjacent support rods 13. Similarly, the negative pressure positioning of the substrate and the grinding processing of the other two sides of the substrate can be achieved. In summary, when the edge of the substrate is processed, the number of transfers of the substrate is reduced, which facilitates the grinding processing of the edge of the substrate. The overall grinding processing process of the four sides of the substrate is relatively simple, thereby shortening the processing time and improving the processing efficiency.

[0041] In this embodiment, the limiting member 21 includes a column 211 which is vertically fixedly mounted on the top of the mounting block 2. An annular rubber block 212 is sleeved on the outside of the column 211. A limiting bolt 213 for limiting the annular rubber block 212 is threadedly connected to the top of the column 211. The limiting bolt 213 can be removed to cancel the limiting of the annular rubber block 212, so that the annular rubber block 212 can be easily removed and replaced. When in use, the mounting block 2 is simultaneously displaced toward the substrate along the slide groove 135 through a plurality of electric sliders located on both sides of the substrate. When the mounting block 2 is displaced, the annular rubber block 212 is driven to move through the column 211. When the annular rubber blocks 212 located on both sides of the substrate are in contact with the substrate, the substrate placed on the plurality of support rods 13 can be limited, so that the substrate is centrally placed on the plurality of support rods 13.

[0042] In this embodiment, the grinding mechanism 4 includes a mounting plate 41 fixedly mounted on the bottom of the sliding block 35, a vertical telescopic rod 42 is symmetrically fixedly mounted on the bottom of the mounting plate 41, a connecting frame 43 is fixedly mounted on the bottom of the two telescopic rods 42, a driving rod 44 connected to the connecting frame 43 is fixedly mounted on the bottom of the mounting plate 41, a supporting plate 45 is installed on the bottom of the connecting frame 43, a horizontal mounting shaft 46 is rotatably mounted on the supporting plate 45, a grinding disc 47 is detachably fixedly mounted on one end of the mounting shaft 46 by a screw, a motor 48 for driving the mounting shaft 46 to rotate is fixedly mounted on the supporting plate 45, and when in use, the edge of the substrate located between two adjacent supporting rods 13 is ground. During grinding, the electromagnetic slider 33 is used to make the sliding block 32 slide at the bottom of the slide rail 31, so that the grinding disc 47 is displaced to above the edge of the substrate between the two support rods 13. At this time, the connecting frame 43 is displaced downward along the two telescopic rods 42 through the driving rod 44, so that the grinding disc 47 is inserted between the two support rods 13, and then the grinding disc 47 is brought into contact with the edge of the substrate through the cooperation of the electromagnetic slider 33, and the control motor 48 is turned on to make the mounting shaft 46 rotate on the support plate 45, so as to drive the grinding disc 47 to rotate and grind the substrate.

[0043] Embodiment 2

[0044] like Figure 1-Figure 9 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0045] In this embodiment, the rotation and translation mechanism 5 includes a slide rail 3 51 fixedly mounted on the inner top wall of the mounting frame 3 and located on one side of the slide rail 1 31. The slide rail 3 51 is the same length as the slide rail 1 31. A slide block 3 52 is slidably mounted at the bottom of the slide rail 3 51.

The bottom of the mounting plate 2 54 A driving rod 541 connected to a connecting frame 56 is fixedly installed at the bottom, a vertical rotating shaft 561 is rotatably installed on the connecting frame 56, a fixing frame 562 is fixedly installed at the bottom of the rotating shaft 561, a motor 563 for driving the rotating shaft 561 to rotate is fixedly installed on the connecting frame 56, a horizontal plate 57 is fixedly installed at the bottom of the fixing frame 562, a cavity 571 is opened in the horizontal plate 57, a plurality of vacuum suction cups 58 connected to the inside of the cavity 571 are fixedly installed at the bottom of the horizontal plate 57, and a vacuum suction cup 58 connected to the inside of the cavity 571 is fixedly installed at the top of the horizontal plate 57. It is worth noting that the other end of the negative pressure tube 59 is connected to the external negative pressure device. When in use, the electromagnetic slider 3 53 is used to make the sliding block 3 52 slide at the bottom of the slide rail 3 51, so that the horizontal plate 57 is located above the substrate, and the connecting frame 2 56 is moved downward along the two telescopic rods 2 55 by the driving rod 2 541, so that the multiple vacuum suction cups 2 58 are in contact with the substrate, and then the external negative pressure device is controlled to draw out the air in the cavity 571 through the negative pressure tube 59 so that negative pressure is formed in the cavity 571, so that negative pressure is formed in the multiple vacuum suction cups 2 58. The suction cups 2 58 are all in contact with the substrate, so that the substrate can be fixed by multiple vacuum suction cups 2 58. At this time, the connecting frame 2 56 is moved upward along the two telescopic rods 2 55 by driving the rod 2 541, so that the substrate is not in contact with the vacuum suction cup 15. The sliding block 3 52 is made to slide at the bottom of the slide rail 3 51 by the electromagnetic slider 3 53, so that the substrate can be translated. When the substrate needs to be rotated, the rotating shaft 561 is rotated by the motor 2 563, so that the horizontal plate 57 can be driven to rotate through the fixed frame 562, and the substrate can be driven to rotate, which is convenient for control.

[0046] In this embodiment, the two ends of the slide rail 1 31 and the slide rail 3 51 extend to the outside of the two frames 1 respectively, and a vertical rotating rod 451 is fixed to the top of the support plate 45.

The connecting frame 1 43 is fixedly mounted with a motor 3 431 for driving the rotating rod 451 to rotate. By setting the two ends of the slide rail 1 31 and the slide rail 3 51 to extend to the outside of the two frames 1 respectively, and then the electromagnetic slider 1 33 is used to make the sliding block 1 32 slide at the bottom of the slide rail 1 31, and the grinding mechanism 4 is driven to move to grind the edge of the substrate, the electromagnetic slider 3 53 can be used to make the sliding block 3 52 slide at the bottom of the slide rail 3 51, so that the horizontal plate 57 is displaced to the two frames 1. On the outside of one side, the grinding mechanism 4 makes way for the grinding mechanism 4. On the contrary, when the substrate placed on the multiple support rods 13 is rotated or translated by the rotating and translating mechanism 5, the sliding block 32 can be made to slide at the bottom of the slide rail 31 through the electromagnetic slider 33, so that the grinding mechanism 4 is moved to the outside of one side of the two frames 1, so as to make way for the rotating and translating mechanism 5. By arranging the support plate 45 to be rotatably installed at the bottom of the connecting frame 43 through the rotating rod 451, when the edge of the substrate is ground, the motor 431 can be controlled to rotate the rotating rod 451, thereby driving the support plate 45 to rotate around the rotating rod 451, so that the grinding disk 47 is away from the side of the support plate 45 and contacts the edge of the substrate, which is beneficial to the grinding of the edge of the substrate.

[0047] In the present embodiment, a plurality of vent holes 136 are provided at the top of the support rod 13 along the length direction of the support rod 13, and the vent holes 136 are connected to the inside of the vent cavity 131. A blocking member 6 is installed on the support rod 13 and located in the vent holes 136, which is used to block or unblock the plurality of vent holes 136. Specifically, it should be noted that in the present embodiment, an air supply pump is also provided in the pump box 16. By providing the vent holes 136, after the grinding process on the edge of the substrate is completed, the substrate is transferred to one side of the two frames 1 by the rotating translation mechanism 5, and then the substrate is transferred to the next processing step by the external vacuum suction cup manipulator. During this period, gas is transported into the vacuum box 121 by the air supply pump in the pump box 16, and the solenoid valves 134 in the vacuum box 121 are controlled to be fully opened.
