Description

Technical Field

[0001] This invention relates to the field of mechanical design, positioning, and manufacturing, specifically to a high-temperature resistant raw material wafer stringing and positioning device. Background Technology

[0002] In the early stages, the quality of short roller coating directly affected the production of glass substrates. Due to the thickness deviation after the high-temperature resistant sheet was squeezed and compressed, the hardness difference range on the circumference of the material after processing and forming increased. The high-temperature resistant sheet contacted the glass plate and pulled the glass downward. The uneven daily wear of the high-temperature resistant sheet caused uneven wear during the use of the high-temperature resistant sheet.

[0003] During short-roller coating operations, due to the inconsistent thickness of the high-temperature resistant raw sheets, there is a certain thickness deviation after multiple sheets are stacked together. Since the coating fixture lacks limiting positions, the stacked raw sheets are threaded onto the shaft to be coated and then placed onto the fixture as a whole. An intermediate transition device acts on the stacked raw sheets, and a hydraulic cylinder pushes the intermediate transition device onto the raw sheets, causing them to deform and compress. However, the transition device is prone to tilting due to the uneven thickness of the stacked raw sheets, and the measured thickness of the compressed raw sheets is inconsistent. Therefore, a secondary compression is required by rotating the entire stacked raw sheets to improve the uniformity of the coated raw sheet thickness. Furthermore, since the thickness of the stacked raw sheets is greater than the actual length of the coating shaft, the stacked raw sheets need to be compressed multiple times during the coating process to fully penetrate the shaft. Therefore, a high-temperature resistant raw sheet threading and positioning device is urgently needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature resistant wafer stringing and positioning device to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a high-temperature resistant raw wafer stringing and positioning device is provided, including an upper worktable. A guide post is fixedly installed at the bottom of the upper worktable, and a transition fixture is movably installed on the guide post. A hydraulic cylinder is screwed to the bottom surface of the upper worktable, and the piston rod of the hydraulic cylinder is connected to the guide rod through a cylinder connector and bolts. Multiple sets of stacked raw wafers are evenly arranged on the side of the guide rod away from the cylinder connector, and a limit piece is provided at the bottom of the stacked raw wafers. A roller core is installed at the bottom of the guide rod and passes through the lower worktable. A positioning reference block is fixedly installed at the bottom of the roller core, and two sets of positioning reference blocks are linearly arranged at the bottom of the roller core. The upper and lower worktables are arranged in parallel.

[0006] Furthermore, the top of the guide rod is inserted into the inside of the cylinder connector and fixed to the piston rod of the hydraulic cylinder, and the guide rod and the cylinder connector are detachable.

[0007] Furthermore, the guide rod and the roller core are coaxially arranged, and their central axes coincide, while the diameters of the guide rod and the roller core are the same.

[0008] Furthermore, four sets of guide pillars are evenly installed at the bottom of the upper worktable, and the four sets of guide pillars are respectively inserted into the interior of four sets of guide cylinders evenly arranged on the transition tooling.

[0009] Furthermore, the transition fixture is driven to rise and fall by a hydraulic cylinder, and the transition fixture rises and falls along the guide column as a trajectory, while the guide column and guide rod are arranged in parallel.

[0010] Furthermore, a positioning seat is fixedly installed at the end of the guide rod away from the hydraulic cylinder connector, and a positioning tip is provided at the bottom of the positioning seat, while a center hole is provided at the bottom of the positioning tip.

[0011] Furthermore, the central hole is opened at the top of the roller core, and the size of the central hole is adapted to the positioning tip. At the same time, the positioning tip is inserted into the interior of the central hole, and the cross-sections of both the central hole and the positioning tip are tapered. The depth of the central hole is equal to the height of the positioning tip.

[0012] Furthermore, a limiting hole is provided on the upper side of the positioning seat, and a limiting piece is provided on one side of the limiting hole. The limiting piece is adapted to the size of the limiting hole, and the limiting piece is rectangular. The end of the limiting piece is inserted into the inside of the limiting hole.

[0013] Furthermore, a force-bearing opening is provided on the right side surface of the limiting piece, and the force-bearing opening is strip-shaped. At the same time, a limiting strip is fixedly provided on the outer side of the limiting piece, and the limiting strip is arc-shaped. The limiting strip is adapted to the size of the positioning seat, and the limiting strip is snapped onto the outer side of the positioning seat. Meanwhile, the multi-layer stacked original pieces installed at the bottom of the guide rod are limited by the limiting piece inserted inside the limiting hole.

[0014] Furthermore, the roller core and the guide rod are positioned and installed through a positioning tip and a center hole, and the roller core and the guide rod are detachable.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention solves the problem that the axial length of the roller core coating section is less than the thickness of the high-temperature resistant sheet to be coated by forming a whole with the guide rod and the roller core. The high-temperature resistant sheet to be coated is threaded onto the guide rod in one go, and the upper limit plate is inserted to prevent the sheet from falling. As the hydraulic cylinder drives the transition tool to move downward to the appropriate position, the upper limit plate is removed. The high-temperature resistant sheet is automatically threaded onto the roller core to be coated under the influence of gravity. This solves the problem of multiple repetitive operations after the high-temperature resistant material is divided into several groups in the early stage, reduces the difficulty of operation, and improves the efficiency of the coating work.

[0017] 2. This invention addresses the issue of controlling the flatness of the upper and lower tooling during the coating process and the one-time extrusion molding of multiple original sheets after stacking. To stabilize the flatness control of the upper and lower tooling, ensure the uniformity of the thickness of the high-temperature resistant original sheet during extrusion, and solve the problem of the coating axis being less than the thickness of the high-temperature resistant original sheet to be coated during operation, this invention avoids multiple sheet insertion operations and provides a simple and convenient operation method.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] Detailed implementation method one: Please refer to Figure 1-6This invention provides a technical solution: a high-temperature resistant raw sheet stringing and positioning device, including an upper worktable 1, a guide post 2 fixedly installed at the bottom of the upper worktable 1, and a transition fixture 4 movably installed on the guide post 2. A hydraulic cylinder 31 is screwed to the bottom surface of the upper worktable 1, and the piston rod of the hydraulic cylinder 31 is connected to a guide rod 8 via a cylinder connector 3 and bolts. Multiple sets of stacked raw sheets 9 are evenly arranged on the side of the guide rod 8 away from the cylinder connector 3, and a limiting piece 10 is provided at the bottom of the stacked raw sheets 9. A roller core 5 is installed at the bottom of the guide rod 8, and the roller core 5 passes through a lower worktable 7. A positioning reference block 6 is fixedly installed at the bottom of the roller core 5, and two sets of positioning reference blocks 6 are linearly arranged at the bottom of the roller core 5. The upper worktable 1 and the lower worktable 7 are arranged in parallel.

[0029] Working Principle: The existing short roller coating equipment frame is optimized by adding a guide column device between the upper worktable 1 and the lower worktable 7. The guide column device consists of four sets of parallel, elevated guide columns 2, which are perpendicular to the upper and lower worktables. The transition fixture 4 is parallel to the worktable surface on both sides and is designed on the four sets of guide columns 2. It moves up and down with the hydraulic cylinder 31 to ensure that the high-temperature resistant sheet can maintain its perpendicularity to the table surface after being deformed by force, and is not affected by the uneven thickness of the high-temperature resistant material itself. The two bearing stops at the bottom of the coating roller core 5 are designed as positioning reference blocks 6, which are located on the hydraulic cylinder connecting part 3. Add guide holeFurthermore, the guide rod 8 is concentric with the two bearing axes at the bottom of the coating roller core 5. A guide rod 8 is then fabricated and fitted with the cylinder connector 3 with a clearance fit. The guide rod 8 has a smooth surface and high hardness treatment to ensure it can move freely up and down along the cylinder connector 3. The bottom of the guide rod 8 is positioned and installed on the roller core 5 via a positioning tip 83 and a center hole 831. When the hydraulic cylinder 31 moves downwards, causing the intermediate transition fixture 4 to move to the appropriate position, the fastening bolts on the cylinder connector 3 are loosened. This allows the positioning tip 83 of the guide rod 8 to align with the center hole 831 on the roller core 5, forming a single unit. This solves the problem that the axial length of the coating section of the roller core 5 is less than the thickness of the high-temperature resistant sheet to be coated, allowing the high-temperature resistant sheet to be coated to be coated in one pass. The original sheet is threaded onto the guide rod 8, and the upper limit plate 10 is inserted to prevent the original sheet from falling. As the hydraulic cylinder 31 drives the transition tool 4 to move downward to the appropriate position, the upper limit plate 10 is removed. Under the influence of gravity, the high-temperature resistant original sheet is automatically threaded onto the roller core 5 to be coated. This solves the problem of multiple repetitive operations after the high-temperature resistant material is divided into several groups in the early stage, reduces the difficulty of operation, and improves the efficiency of coating work. Since the coating process involves the control of the flatness of the upper and lower tooling and the one-time extrusion molding after multiple original sheets are stacked, in order to stabilize the control of the flatness of the upper and lower tooling, ensure the uniformity of the thickness of the high-temperature resistant original sheet during the extrusion process, and solve the problem that the coating shaft length is less than the thickness of the high-temperature resistant original sheet to be coated during the operation, avoid multiple sheet threading operations and provide a simple and convenient operation method.

[0033] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 4. The transition tooling 4 is driven to rise and fall by the hydraulic cylinder 31, and the transition tooling 4 rises and falls along the guide column 2 as the trajectory. At the same time, the guide column 2 and the guide rod 8 are arranged in parallel.

[0034] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One. The end of the guide rod 8 away from the oil cylinder connector 3 is fixedly installed with a positioning seat 82, and the bottom of the positioning seat 82 is provided with a positioning tip 83. At the same time, the bottom of the positioning tip 83 is provided with a center hole 831.

The central hole 831 is opened on the top of the roller core 5, and the size of the central hole 831 is adapted to the positioning tip 83. At the same time, the positioning tip 83 is inserted into the interior of the central hole 831, and the cross-sections of the central hole 831 and the positioning tip 83 are both tapered. The depth of the central hole 831 is equal to the height of the positioning tip 83.

The upper side of the positioning seat 82 is provided with a limiting hole 81, and a limiting piece 10 is provided on one side of the limiting hole 81. At the same time, the size of the limiting piece 10 is adapted to the limiting hole 81, and the limiting piece 10 is rectangular.

The limiting strip 102 is adapted to the size of the positioning seat 82, and the limiting strip 102 is snapped onto the outer side of the positioning seat 82. Meanwhile, the multi-layer stacked original piece 9 installed at the bottom of the guide rod 8 is limited by the limiting piece 10 inserted inside the limiting hole 81.

[0038] Specific Implementation Method 10: This implementation method is a further limitation of Specific Implementation Method 1. The roller core 5 and the guide rod 8 are positioned and installed through the positioning tip 83 and the center hole 831, and the roller core 5 and the guide rod 8 are detachable.

[0039] The coating roller core 5 is positioned by bearing stops to ensure that the axis of the roller core 5 is perpendicular to the worktable surface. The guide posts on both sides of the worktable are perpendicular to the worktable surface. The transition fixture 4 and the hydraulic cylinder connector 3 are bolted to the guide post 2 and move up and down along the guide post 2 to ensure verticality and flatness of the transition fixture 4 and the worktable surface. After the guide hole on the hydraulic cylinder connector 3 is positioned with the roller core 5 to be coated by the bearing stop positioning block, the center of the hole is concentric with the axis of the bearing stop. This design ensures that the guide rod moves up and down along the hydraulic cylinder connector 3 and is concentric with the axis of the roller core 5, providing a guarantee for the subsequent one-time sheet stringing operation. The guide rod 8 is designed with a positioning tip 83 that cooperates with the center hole 831 of the roller core 5. The limiting hole 81 at the bottom of the guide rod 8 is inserted with a limiting piece 10 to ensure that the stacked original sheets do not slip due to gravity.
