Description

Technical Field

[0001] This invention relates to the field of flat glass stacking technology, specifically an adjustable balanced clamping device for flat glass stacking and its usage method. Background Technology

[0002] Glass stacking equipment is commonly used in glass production lines to unload glass sheets from the production line.

[0003] Currently, the stacking equipment on the market mainly adopts two stacking and glass placement methods: one is that after the glass is placed, the stacking host moves on its own or moves together with the stacking trolley to press the glass; the other is that after the glass is placed, there is no pressing action, and the stacking is completed by directly placing the glass through a precise control program.

[0004] The above method has the following drawbacks: the stacking cycle is relatively long during use, and the lower edge of the glass comes into direct contact with the non-metallic tray at the bottom of the glass frame during the pressing process, which poses a risk of scratches and damage, and greatly reduces the service life of the non-metallic tray. In addition, the above method has a large pre-reserved stacking gap, which may result in insufficient stacking tightness. It also requires higher processing precision of parts, as well as higher requirements for assembly and debugging procedures, which directly leads to higher equipment costs. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems and deficiencies by providing an adjustable balanced clamping device and method for stacking flat glass, thereby improving overall work efficiency.

[0006] The technical problem solved by this invention is:

[0007] (1) During the pressing process, the lower edge of the glass comes into direct contact with the non-metallic tray at the bottom of the glass holder, which poses a risk of scratches and damage, and greatly reduces the service life of the non-metallic tray.

[0008] (2) If the program reserves a large stacking gap, there will be insufficient stacking compactness, which will require higher processing accuracy of parts, assembly and debugging procedures, and higher cost.

[0009] (3) The stacking cycle is relatively long.

[0010] The objective of this invention can be achieved through the following technical solution: an adjustable balanced clamping device for stacking flat glass, comprising a working support, a sliding support slidably mounted on the working support, an L-shaped receiving frame mounted on one side of the sliding support, a lifting and counter-pushing mechanism mounted on the working support and on both sides of the L-shaped receiving frame, a sliding motor for moving the sliding support installed inside the working support, the lifting and counter-pushing mechanism comprising a first mounting plate fixed on the working support, a worm gear push rod provided on the first mounting plate, a lifting support block provided at the telescopic end of the worm gear push rod, a counter-pushing crossbar spliced ​​between the two lifting support blocks, a clamping push rod mounted on the lifting support block, and a clamping rod mounted at the telescopic end of the clamping push rod.

[0011] As a further embodiment of the invention, a first adjusting plate is mounted on the first mounting plate, a first support plate is mounted on the bottom of the worm gear push rod, and several adjusting grooves are evenly distributed at equal intervals on both the upper and lower sides of the first adjusting plate. Several positioning bolts are threaded through both the first mounting plate and the first support plate.

[0012] As a further embodiment of the invention, a second support plate is installed at the telescopic end of the worm gear push rod, and a limit slide rod is installed at both ends of the second support plate. The limit slide rod is sleeved with a limit cylinder, and the limit cylinder passes through and is installed at both ends of the first support plate.

[0013] As a further embodiment of the invention, a limiting guide rail is installed in the middle of the upper surface of the second support plate, and the lower part of the lifting support block is slidably connected to the limiting guide rail. A limiting plate is installed at the end of the second support plate away from the L-shaped receiving frame, and an adjusting frame is installed at the end of the second support plate closer to it. A spring rod is installed on the limiting plate, and an adjusting bolt is installed on the adjusting frame. The two sides of the lifting support block abut against the spring rod and the adjusting bolt, respectively.

[0014] As a further embodiment of the invention, a mounting groove is provided in the middle of the lifting support block, and a clamping push rod is installed in the mounting groove. A second mounting plate is installed on the telescopic end of the clamping push rod, and the clamping rod passes through the second mounting plate. Limiting bolts are threaded through both the second mounting plate and the lifting support block, and clamping plates are installed on the opposite ends of the two clamping rods.

[0015] As a further embodiment of the invention, a second adjusting plate is installed on one side of the first support plate, and a proximity switch is spliced ​​onto the second adjusting plate.

[0016] As a further embodiment of the invention, a buffer plate is spliced ​​and installed on the side of the push bar near the glass plate. The side of the buffer plate is flush with the vertical plane of the lifting support block, and a limit clamp is installed on the opposite side of the lifting support block.

[0017] As a further embodiment of the invention, the lifting support block has a vertical surface and an inclined surface on the side near the L-shaped support frame. The vertical surface is perpendicular to the surface where the second support plate is located, and the inclined surface has an angle with the surface where the second support plate is located. The inclined surface and the vertical surface intersect to form a corner seam. The side of the inclined surface is set as a positioning edge, and the corner seam abuts against the lower edge of the glass plate. The height of the positioning edge is always lower than the support surface of the L-shaped support frame.

[0018] A method for using an adjustable balanced clamping device for stacking flat glass, comprising the following steps:

[0019] Step 1: Initial assembly of the L-shaped support frame and the lifting and reverse thrust mechanism;

[0020] Step 2: Adjust the tilt angle and position of the L-shaped support frame and the lifting support block;

[0021] Step 3: Begin stacking, lifting support blocks to raise the flat glass;

[0022] Step 4: Eliminate the gap between the flat glass and the L-shaped support frame, then reposition it;

[0023] Step 5: Repeat and complete the pressing.

[0024] The beneficial effects of this invention are:

[0025] (1) During operation, the stacking host continuously picks up a flat glass sheet from the glass production line and places it on the L-shaped receiving frame for stacking. When the stacking host is reset and picks up the next sheet, the lifting and reverse pushing mechanism is activated. The sliding support is driven by the sliding motor to move the L-shaped receiving frame and the flat glass sheet it carries toward the lifting and reverse pushing mechanism. When the lifting and reverse pushing mechanism senses that a flat glass sheet is approaching, the worm gear push rod pushes the lifting support block to abut against the lower edge of the flat glass sheet and lift it up. Under the limit of the lifting support block and the reverse pushing crossbar, the flat glass sheet moves in the opposite direction as the sliding support moves, so that the side of the flat glass sheet is perpendicular to the vertical side of the L-shaped receiving frame. The walls abut against each other, expelling the air between them and eliminating the gap. When the lifting and pushing mechanism senses the elimination of the gap, the worm gear push rod moves down to lift the support block, separating it from the lower edge of the flat glass. This allows the lower edge of the flat glass to abut against the L-shaped receiving frame again. Subsequently, the sliding motor moves the sliding bracket in the opposite direction, creating a gap between the lifting and pushing mechanism and the previous flat glass. This causes the L-shaped receiving frame to return to the new receiving position, and the lifting and pushing mechanism resets synchronously. After the stacking host has placed the next glass plate, the above steps are repeated to complete the pressing of the flat glass piece by piece. During the pressing process, there is no contact wear on the lower edge of the glass plate, greatly increasing the service life of each component.

[0026] (2) During operation, the positioning bolt slides within the adjusting groove and tightly clamps the first adjusting plate. This allows for adjustment of the tilt angle between the first mounting plate and the first adjusting plate, as well as the tilt angle between the first support plate and the first adjusting plate, by adjusting the groove and the positioning bolt. It also adjusts the height of the first support plate, ensuring that the tilt surface of the lifting support block forms an angle with the receiving plane of the L-shaped receiving frame. The position and height of the lifting support block are further accurately adjusted using the adjusting bolt and spring rod. A buffer plate provides cushioning to prevent damage to the lower edge of the glass plate during clamping. A limiting cylinder limits the limiting slide rod. Simultaneously, as the sliding bracket retracts, the higher end of the receiving plane of the L-shaped receiving frame continuously approaches the lifting reverse thrust mechanism. The precise extension and retraction of the worm gear push rod ensures that the lifting support block and the reverse push bar are always higher than the previous stacking and clamping position after each reset. Furthermore, the lifting height of the lifting support block and the reverse push bar is consistent with the lifting height of the L-shaped receiving frame's receiving plane. When the lifting support block raises the glass plate, the clamping push rod retracts, and the clamping rod pushes the clamping plate to clamp and position the glass plate on both sides, ensuring that the sides of each glass plate remain flush. This improves the flatness of the sides after stacking. The position of the clamping push rod and the clamping rod can be adjusted using limit bolts to accommodate glass plates of different widths. This allows the glass plates to eliminate gaps and maintain flatness on both sides during stacking, facilitating packaging and transportation, preventing damage due to unevenness, and improving the yield rate during transportation.

[0027] (3) During operation, the position of the lower edge of the glass plate is detected by the proximity switch and a signal for the extension of the worm gear push rod is sent to quickly lift the lifting support block. Through the accurate extension and retraction of the worm gear push rod, the lower edge of the flat glass is accurately separated from the receiving plane of the L-shaped receiving frame, and the height of the corner gap is accurately higher than the receiving plane of the L-shaped receiving frame and the height of the positioning edge is lower than the L-shaped receiving frame. By monitoring the compression of the spring rod in real time, the moment when the gap is eliminated is determined and a signal for the reverse sliding bracket is sent. The movement distance of each component is short and fast, and the whole process takes very little time. It can be matched with the grabbing time interval of the stacking host. The stacking host only needs to grab the glass plate one piece at a time without additional alignment. The whole process is fast and efficient. Attached Figure Description

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] Please see Figure 1-5 As shown: An adjustable balanced clamping device for stacking flat glass includes a working support 1, a sliding support 2 slidably mounted on the working support 1, an L-shaped receiving frame 3 mounted on one side of the sliding support 2, a lifting and pushing mechanism 4 mounted on the working support 1 and on both sides of the L-shaped receiving frame 3, a sliding motor 35 for moving the sliding support 2 is installed inside the working support 1, the lifting and pushing mechanism 4 includes a first mounting plate 5, the first mounting plate 5 is fixed on the working support 1, a worm gear push rod 8 is provided on the first mounting plate 5, a lifting support block 15 is provided at the telescopic end of the worm gear push rod 8, a pushing crossbar 17 is spliced ​​between the two lifting support blocks 15, a clamping push rod 19 is installed on the lifting support block 15, and a clamping rod 21 is installed at the telescopic end of the clamping push rod 19;

[0037] In this embodiment, during operation, the stacking host sequentially picks up one sheet of flat glass from the glass production line and places it on the L-shaped receiving frame 3 for stacking. When the stacking host finishes placing the sheet and resets to pick up the next sheet, the lifting and reverse-pushing mechanism 4 is activated. The sliding motor 35 drives the sliding bracket 2, moving the L-shaped receiving frame 3 and the flat glass it carries towards the lifting and reverse-pushing mechanism 4. When the lifting and reverse-pushing mechanism 4 senses an approaching flat glass, the worm gear push rod 8 pushes the lifting support block 15, which abuts against both sides of the lower edge of the flat glass and is lifted. Under the limitation of the lifting support block 15 and the reverse-pushing crossbar 17, the flat glass moves in the reverse direction as the sliding bracket 2 continues to move. The side of the flat glass abuts against the vertical side wall of the L-shaped receiving frame 3, expelling the air between them and eliminating the gap. When the lifting and pushing mechanism 4 senses the elimination of the gap, the worm gear push rod 8 moves down to lift the support block 15, separating it from the lower edge of the flat glass, so that the lower edge of the flat glass abuts against the L-shaped receiving frame 3 again. Then, the sliding motor 35 moves the sliding bracket 2 in the opposite direction, creating a gap between the lifting and pushing mechanism 4 and the previous flat glass, so that the L-shaped receiving frame 3 returns to the new joint position. The lifting and pushing mechanism 4 resets synchronously. After the stacking host has placed the next glass plate, the above steps are repeated to complete the pressing of the flat glass piece by piece.

[0038] A first adjusting plate 6 is installed on the first mounting plate 5, and a first support plate 7 is installed at the bottom of the worm gear push rod 8. Several adjusting grooves 28 are evenly distributed at equal intervals on both the upper and lower sides of the first adjusting plate 6. Several positioning bolts 29 are threaded through the first mounting plate 5 and the first support plate 7. The positioning bolts 29 correspond to the adjusting grooves 28 one by one. During operation, the positioning bolts 29 slide in the adjusting grooves 28 and tightly clamp the first adjusting plate 6. Thus, by adjusting the limiting of the adjusting grooves 28 and the positioning bolts 29, the tilt angle between the first mounting plate 5 and the first adjusting plate 6 and the tilt angle between the first support plate 7 and the first adjusting plate 6 are adjusted, and the height position of the first support plate 7 is adjusted so that the tilt surface 32 of the lifting support block 15 has an angle with the receiving plane of the L-shaped receiving frame 3.

[0039] A second support plate 9 is installed at the telescopic end of the worm gear push rod 8, and the axis of the worm gear push rod 8 is perpendicular to both the first support plate 7 and the second support plate 9. Limiting slide rods 10 are installed at both ends of the second support plate 9. Limiting slide rods 10 are sleeved with limiting cylinders 11, which pass through and are installed at both ends of the first support plate 7. During operation, the limiting cylinders 11 limit the limiting slide rods 10. Through the accurate telescopic movement of the worm gear push rod 8, the lower edge of the flat glass is accurately separated from the receiving plane of the L-shaped receiving frame 3, and the corner seam is accurately closed. The height of 33 is higher than the receiving plane of the L-shaped receiving frame 3, and the height of the positioning edge 34 is lower than the L-shaped receiving frame 3. At the same time, as the L-shaped receiving frame 3 continues to retract with the sliding bracket 2, the higher end of the receiving plane continuously approaches the lifting and counter-pushing mechanism 4. Through the accurate extension and retraction of the worm gear push rod 8, the lifting support block 15 and the counter-pushing crossbar 17 are higher than the previous stacking and pressing position after each reset, and the lifting height of the lifting support block 15 and the counter-pushing crossbar 17 is consistent with the lifting height of the receiving plane of the L-shaped receiving frame 3 each time.

[0040] A limiting guide rail 12 is installed in the middle of the upper surface of the second support plate 9. The lower part of the lifting support block 15 is slidably connected to the limiting guide rail 12. A limiting plate 13 is installed at the end of the second support plate 9 away from the L-shaped support frame 3, and an adjusting frame 26 is installed at the end of the second support plate 9 closer to it. A spring rod 14 is installed on the limiting plate 13, and an adjusting bolt 27 is installed on the adjusting frame 26. The two sides of the lifting support block 15 abut against the spring rod 14 and the adjusting bolt 27, respectively. During operation, the position and height of the lifting support block 15 are further and accurately adjusted by the adjusting bolt 27 and the spring rod 14. When the lifting support block 15 and the counter-pushing crossbar 17 push against the glass plate, the elasticity of the spring rod 14 reduces the impact damage to the glass plate. At the same time, a sensor for monitoring the compression of the spring rod 14 is installed inside the spring rod 14. By monitoring the compression of the spring rod 14 in real time, the moment when the gap is eliminated is determined and a signal for the counter-pushing sliding bracket 2 is sent.

[0041] Each of the opposite sides of the lifting support block 15 is equipped with a limiting clamping block 16 for splicing and installing the reverse push crossbar 17. The middle of the lifting support block 15 is provided with an installation groove 30. The clamping push rod 19 is installed in the installation groove 30. The two clamping push rods 19 are symmetrically arranged. The telescopic end of the clamping push rod 19 is equipped with a second mounting plate 20. The clamping rod 21 passes through the second mounting plate 20. The second mounting plate 20 and the lifting support block 15 are both threaded with limiting bolts 25. The two clamping rods 21 are coaxial and their axis is parallel to the bearing plane of the L-shaped support frame 3. Each of the opposite ends of the two clamping rods 21 is equipped with a clamping plate 22. The side of the clamping plate 22 is flush with the L-shaped side wall of the lifting support block 15.

[0042] In this embodiment, when the lifting support block 15 lifts the glass plate, the clamping push rod 19 retracts, and the clamping rod 21 pushes the clamping plate 22 to clamp and position the two sides of the glass plate, so that the two sides of each glass plate remain flush, improving the flatness of the side of the stacked glass plates. The position of the clamping push rod 19 and the clamping rod 21 is adjusted by the limiting bolt 25 to adapt to glass plates of different widths.

[0043] A second adjusting plate 23 is installed on one side of the first support plate 7. A proximity switch 24 is spliced ​​on the second adjusting plate 23. When working, the proximity switch 24 detects the position of the lower edge of the glass plate and sends a signal for the extension of the worm gear push rod 8, which quickly raises the lifting support block 15.

[0044] The lifting support block 15 has a vertical surface 31 and an inclined surface 32 on the side near the L-shaped support frame 3. The vertical surface 31 is perpendicular to the surface of the second support plate 9, and the inclined surface 32 forms an angle with the surface of the second support plate 9. The inclined surface 32 and the vertical surface 31 intersect to form a corner seam 33. The side of the inclined surface 32 is set as a positioning edge 34. The corner seam 33 abuts against the lower edge of the glass plate. The height of the positioning edge 34 is always lower than the support surface of the L-shaped support frame 3. During operation, the height of the corner seam 33 is measured by checking the relationship between the corner seam 33 and the L-shaped support frame 3. The relative height of the L-shaped support frame 3's receiving surface determines whether the glass plate is lifted and separated from the receiving surface of the L-shaped support frame 3. The relative height of the positioning edge 34 and the receiving surface of the L-shaped support frame 3 is detected to determine whether the lifting is excessive. It ensures that each lifting operation places the receiving surface of the L-shaped support frame 3 between the corner seam 33 and the positioning edge 34. This protects the receiving surface of the L-shaped support frame 3 from rubbing against the glass plate and ensures that the lifting support block 15 does not obstruct the contact between the lower edges of the front and rear glass plates after lifting.

[0045] A buffer plate 18 is spliced ​​and installed on the side of the push bar 17 near the glass plate. The side of the buffer plate 18 is flush with the vertical surface 31 of the lifting support block 15. The buffer plate 18 provides cushioning to prevent damage to the lower edge of the glass plate when it is pressed.

[0046] A method for using an adjustable balanced clamping device for stacking flat glass, comprising the following steps:

[0047] Step 1: Initial assembly, install the L-shaped support frame 3, and adjust the tilt angle of the support plane of the L-shaped support frame 3. Then install the lifting and pushing mechanism 4 on both sides of the L-shaped support frame 3 and above the support plane.

[0048] Step 2: Adjust the tilt angle and position. Based on the tilt angle of the receiving plane of the L-shaped receiving frame 3, adjust the position of the lifting support block 15 and the tilt angle of its inclined surface 32. First, adjust the tilt angle between the first mounting plate 5 and the first adjusting plate 6 and the tilt angle between the first support plate 7 and the first adjusting plate 6 by adjusting the adjustment and limiting of the slide groove 28 and the positioning bolt 29. Then, adjust the height position of the first support plate 7 so that the inclined surface 32 of the lifting support block 15 has an angle with the receiving plane of the L-shaped receiving frame 3. Then, adjust the extension length of the worm gear push rod 8 to adjust the position of the lifting support block 15 and check whether it is operating normally.

[0049] Step 3: Start stacking. First, ensure that the height of the corner seam 33 and positioning edge 34 of the lifting support block 15 is lower than the receiving plane of the L-shaped receiving frame 3. The stacking host continuously grabs a flat glass from the glass production line and places it on the L-shaped receiving frame 3. The lifting and pushing mechanism 4 is activated. The sliding support 2 is driven by the sliding motor 35 to move the L-shaped receiving frame 3 and the flat glass it carries toward the lifting and pushing mechanism 4. When the lifting and pushing mechanism 4 senses that a flat glass is approaching, the worm gear push rod 8 pushes the lifting support block 15 to abut against both sides of the lower edge of the flat glass and lift it. At this time, the lower edge of the flat glass is close to the corner seam 33 of the lifting support block 15. The lifting separates the lower edge of the flat glass from the receiving plane of the L-shaped receiving frame 3. When the height of the corner seam 33 is higher than the receiving plane of the L-shaped receiving frame 3 and the height of the positioning edge 34 is lower than the L-shaped receiving frame 3, the lifting stops.

[0050] Step 4: Push to eliminate gap. Continuously move the sliding bracket 2 and limit the flat glass through the lifting support block 15 and the reverse push crossbar 17, so that the side of the flat glass abuts against the vertical side wall of the L-shaped support frame 3, expelling the air between them and eliminating the gap. When the lifting and reverse push mechanism 4 senses the elimination of the gap, the worm gear push rod 8 moves down to lift the support block 15 and separates it from the lower edge of the flat glass, so that the lower edge of the flat glass abuts against the receiving plane of the L-shaped support frame 3 again. Then the sliding motor 35 moves the sliding bracket 2 in the opposite direction, creating a gap between the lifting and reverse push mechanism 4 and the flat glass, so that the L-shaped support frame 3 returns to the new joint position, and the lifting and reverse push mechanism 4 resets synchronously.

[0051] Step 5: Repeat and complete the pressing. After the stacking host has placed the next glass plate, repeat steps 3 and 4 to press the flat glass plates one by one.

[0052] In use, the operator sequentially picks up a sheet of flat glass from the glass production line using a stacking host and places it on the L-shaped receiving frame 3 for stacking. When the stacking host resets and picks up the next sheet, the lifting and reverse-pushing mechanism 4 is activated. The sliding motor 35 drives the sliding bracket 2, moving the L-shaped receiving frame 3 and the flat glass it carries towards the lifting and reverse-pushing mechanism 4. When the lifting and reverse-pushing mechanism 4 senses an approaching sheet of glass, the worm gear push rod 8 pushes up the lifting support block 15, bringing it into contact with both sides of the lower edge of the flat glass and lifting it. Limited by the lifting support block 15 and the reverse-pushing crossbar 17, the flat glass, as the sliding bracket 2 continues to move, reverses the movement, causing the side of the flat glass to contact the L-shaped receiving frame. The vertical sidewalls of the frame 3 abut against each other, expelling the air between them and eliminating the gap. When the lifting and pushing mechanism 4 senses the elimination of the gap, the worm gear push rod 8 moves down to lift the support block 15, separating it from the lower edge of the flat glass, so that the lower edge of the flat glass abuts against the L-shaped receiving frame 3 again. Then the sliding motor 35 moves the sliding bracket 2 in the opposite direction, creating a gap between the lifting and pushing mechanism 4 and the previous flat glass, so that the L-shaped receiving frame 3 returns to the new receiving position. The lifting and pushing mechanism 4 resets synchronously. After the stacking host finishes placing the next glass plate, the above steps are repeated, thereby completing the pressing of the flat glass piece by piece. During the pressing process, there is no contact wear on the lower edge of the glass plate, greatly increasing the service life of each component.

[0053] During operation, the positioning bolt 29 slides within the adjusting groove 28 and tightly clamps the first adjusting plate 6. This allows for adjustment of the tilt angles between the first mounting plate 5 and the first adjusting plate 6, as well as between the first support plate 7 and the first adjusting plate 6, by adjusting the limiting position of the adjusting groove 28 and the positioning bolt 29. It also adjusts the height of the first support plate 7, ensuring that the tilting surface 32 of the lifting support block 15 forms an angle with the receiving plane of the L-shaped receiving frame 3. The position and height of the lifting support block 15 are further precisely adjusted using the adjusting bolt 27 and the spring rod 14. The buffer plate 18 provides cushioning to prevent damage to the lower edge of the glass plate during clamping. The limiting cylinder 11 limits the limiting slide rod 10. Simultaneously, as the sliding bracket 2 retracts, the higher end of the receiving plane of the L-shaped receiving frame 3 continuously approaches the lifting and counter-pushing mechanism. 4. The precise extension and retraction of the worm gear push rod 8 ensures that the lifting support block 15 and the reverse push crossbar 17 are higher than the previous stacking and pressing position after each reset. The lifting height of the lifting support block 15 and the reverse push crossbar 17 is consistent with the lifting height of the L-shaped receiving frame 3 receiving plane each time. When the lifting support block 15 lifts the glass plate, the clamping push rod 19 retracts, and the clamping rod 21 pushes the clamping plate 22 to clamp and position the two sides of the glass plate, so that the two sides of each glass plate are kept flat, improving the flatness of the side of the glass plate after stacking. The position of the clamping push rod 19 and the clamping rod 21 is adjusted by the limit bolt 25 to adapt to glass plates of different widths, so that the glass plates can eliminate gaps and keep the two sides flat when stacking, which is convenient for packaging and transportation, avoids the inability to withstand bumps due to unevenness, and improves the yield rate during transportation.

[0054] During operation, the proximity switch 24 detects the position of the lower edge of the glass plate and sends a signal for the extension of the worm gear push rod 8, which quickly raises the lifting support block 15. Through the accurate extension and retraction of the worm gear push rod 8, the lower edge of the flat glass is accurately separated from the receiving plane of the L-shaped receiving frame 3, and the height of the corner gap 33 is accurately higher than the receiving plane of the L-shaped receiving frame 3, while the height of the positioning edge 34 is lower than the L-shaped receiving frame 3. By monitoring the compression of the spring rod 14 in real time, the moment when the gap is eliminated is determined and a signal for the reverse sliding bracket 2 is sent. The movement distance of each component is short and fast, and the whole process takes very little time, which can be matched with the grabbing time interval of the stacking host. Moreover, the stacking host only needs to grab the glass plates one by one, without the need for additional alignment. The whole process is fast and efficient.

9. A method of using an adjustable balanced clamping device for stacking flat glass, applied to the adjustable balanced clamping device for stacking flat glass as described in claim 8, characterized in that... The method includes the following steps: Step 1: Initially assemble the L-shaped support frame (3) and the lifting and pushing mechanism (4), install the L-shaped support frame 3, and adjust the tilt angle of the support plane of the L-shaped support frame 3. Then install the lifting and pushing mechanism (4) on both sides of the L-shaped support frame (3) and above the support plane. Step 2: Adjust the inclination angle and position of the L-shaped support frame (3) and the lifting support block (15). According to the inclination angle of the bearing plane of the L-shaped support frame (3), adjust the position of the lifting support block (15) and the inclination angle of its inclined surface (32). First, adjust the inclination angle between the first mounting plate (5) and the first adjusting plate (6) and the inclination angle between the first support plate (7) and the first adjusting plate (6) by adjusting the adjustment and limiting of the slide groove (28) and the positioning bolt (29). Adjust the height position of the first support plate (7) so that the inclined surface (32) of the lifting support block (15) has an angle with the bearing plane of the L-shaped support frame (3). Then adjust the extension length of the worm gear push rod (8) to adjust the position of the lifting support block (15) and check whether it is running normally. Step 3: Begin stacking, lift the support block (15) to raise the flat glass; Step 4: Eliminate the gap between the flat glass and the L-shaped support frame (3), then reset it, continuously move the sliding bracket (2), and limit the flat glass by the lifting support block (15) and the reverse push crossbar (17), so that the side of the flat glass abuts against the vertical side wall of the L-shaped support frame (3) in the reverse direction, remove the air between the two, and eliminate the gap between them. When the lifting and reverse push mechanism (4) senses the elimination of the gap, the worm gear push rod (8) moves down to lift the support block (15) and separates it from the lower edge of the flat glass, so that the lower edge of the flat glass abuts against the bearing plane of the L-shaped support frame (3) again. Then the sliding motor (35) moves the sliding bracket (2) in the reverse direction, and a gap is generated between the lifting and reverse push mechanism (4) and the flat glass, so that the L-shaped support frame (3) returns to the new joint position, and the lifting and reverse push mechanism (4) resets synchronously. Step 5: Repeat and complete the pressing.
