Description

Technical Field

[0001] This utility model relates to the field of quartz tube production technology, specifically to a drying device for quartz tube production. Background Technology

[0002] Quartz glass tubes are a special industrial technical glass made of silicon dioxide, and are an excellent basic material. Due to their superior physical and chemical properties, quartz tubes are widely used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemicals, machinery, power, and environmental protection. To ensure the quality of quartz tubes, they need to be dried.

[0003] In existing technologies, drying devices typically place quartz tubes on a rotating positioning plate for drying. After drying, when changing materials, a robotic arm needs to remove the quartz tubes from the positioning plate and move them to a suitable placement area. Then, undried quartz tubes are picked up from the loading area and placed on the positioning plate. Because there is a certain distance between the placement area and the loading area, the robotic arm needs to travel back and forth between the two areas multiple times, making material changing inconvenient, resulting in long material changing times, wasting a significant amount of time, and leading to low drying efficiency. There is an urgent need for a drying device for quartz tube production to solve these problems. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 As shown, this utility model embodiment provides a drying device for quartz tube production, comprising: The positioning disk 4 is rotated. The top of the positioning disk 4 is equipped with multiple electric positioning grippers 5 for clamping the quartz tube. The outer side of the positioning disk 4 is equipped with a conveyor belt 8 for conveying the quartz tube. Multiple positioning seats 9 for vertically placing the quartz tube are symmetrically arranged on the conveyor belt 8. The positioning disk 4 is equipped with a gripping electric gripper 11. Above the positioning disk 4 is a gripping component 6 for driving the electric gripper 11 to grip the quartz tube and move back and forth between the positioning seat 9 and the electric gripper 5. Below the positioning plate 4 is an air supply component 3 for simultaneously blowing and drying quartz tubes held by multiple positioning electric grippers 5. This design uses a gripping component 6 to drive an electric gripper 11 to grip the quartz tube, moving it back and forth between the positioning seat 9 and the positioning electric gripper 5. When the quartz tube needs to be replaced after drying, the gripping component 6 drives the electric gripper 11 to remove one of the dried quartz tubes from the positioning plate 4 and place it on one of the symmetrically arranged positioning seats 9 on the conveyor belt 8. Then, the undried quartz tube is gripped from the other symmetrically arranged positioning seat 9 and placed on the positioning plate 4. By rotating the positioning plate 4, the quartz tube on the positioning plate 4 is ensured to be directly below the electric gripper 11. This process is repeated, with the gripping component 6 driving the electric gripper 11 to complete the replacement operation of the quartz tubes on the positioning plate 4. Because the positioning seats 9 are symmetrically arranged on the conveyor belt 8, one positioning seat 9 can transport and place undried quartz tubes, while the other positioning seat 9 can transport and place dried quartz tubes. This reduces the moving distance of the electric gripper 11 during material replacement, facilitating the material replacement operation, saving material replacement time, and improving drying efficiency.

[0019] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The positioning electric gripper 5 has positioning grooves 51 that match the quartz tube on one side of its two gripping arms that are close to each other. The gripping electric gripper 11 has gripping grooves 111 that match the quartz tube and are used for laterally gripping the quartz tube on one side of its two gripping arms that are close to each other. This design facilitates the clamping of undried quartz tubes onto the positioning plate 4 using the positioning gripper and the gripping grooves 111 facilitate the clamping of quartz tubes on the symmetrically arranged positioning seats 9 using the gripping grooves 111. The inner walls of both the positioning grooves 51 and the gripping grooves 111 are provided with protective pads that match the side walls of the quartz tube.

[0020] Reference Figure 1 , Figure 2 and Figure 6 The top of the positioning disk 4 has multiple insertion slots 41 that match the positioning electric grippers 5, and the bottom of the positioning disk 4 has drying holes 42 located between the positioning slots 51 at positions corresponding to the positioning electric grippers 5. This design facilitates the installation and placement of the positioning electric grippers 5 through the insertion slots 41; the drying holes 42 facilitate the blowing and drying of the quartz tube at the positioning slots 51; since the drying holes 42 are located at the bottom of the quartz tube, the gas after drying can flow upward along the inner wall of the quartz tube, accelerating the drying speed of the inner wall of the quartz tube, and at the same time, in conjunction with the positioning disk 4 driving the quartz tube to rotate, it accelerates the drying speed of the outer wall of the quartz tube.

[0021] Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 It also includes a base plate 1, a drive motor 2 is provided at the bottom of the base plate 1, and a positioning disk 4 is located above the base plate 1 and connected to the output shaft of the drive motor 2; The air supply assembly 3 includes a sealed bearing 31 embedded in the bottom of the positioning plate 4. The inner wall of the sealed bearing 31 is provided with a second hollow annular plate 36 embedded in the bottom of the positioning plate 4. A first hollow annular plate 32 is embedded in the top of the bottom plate 1. A plurality of connecting pipes 33 are provided between the first hollow annular plate 32 and the second hollow annular plate 36. The top of the second hollow annular plate 36 is provided with an annular groove 37 for connecting the drying hole 42 and the second hollow annular plate 36. A hot air blower 34 is provided at the bottom of the bottom plate 1. An air supply pipe 35 for connecting the hot air blower 34 and the first hollow annular plate 32 is provided inside the bottom plate 1. The design utilizes the hot air blower 34 in the air supply assembly 3 to supply hot air to the first hollow annular plate 32 via the air supply pipe 35. The hot air is then delivered to the interior of the second hollow annular plate 36 via the connecting pipe 33. Finally, the hot air dries the quartz tube held by the positioning electric gripper 5 along the annular groove 37 and the drying hole 42. Through the sealing bearing 31, the second hollow annular plate 36 rotates along the sealing bearing 31 under the action of the connecting pipe 33 when the positioning plate 4 rotates, thereby improving the sealing performance at the connection.

[0022] Reference Figure 2 , Figure 3 and Figure 4 A conductive slip ring 10 is provided between the positioning disk 4 and the base plate 1, located outside the output shaft of the drive motor 2. This design allows for convenient power supply to the positioning electric gripper 5, which rotates with the positioning disk 4, via the conductive slip ring 10.

[0023] Reference Figure 1 and Figure 2 The base plate 1 has multiple columns 71 on its top, and a support plate 7 is located above the positioning plate 4 and between the positioning plate 4 and the conveyor belt 8 between the tops of the multiple columns 71. The gripping component 6 is located at the bottom of the support plate 7. This design facilitates the installation of the gripping component 6 through the support plate 7 and the columns 71.

[0024] Reference Figure 2 The gripping assembly 6 includes a pair of transverse electric cylinders 61 disposed at the bottom of the support plate 7. A connecting plate 62 is disposed between the bottom of the moving blocks of the pair of transverse electric cylinders 61. A longitudinal electric cylinder 63 is disposed at the bottom of the connecting plate 62. An electric push rod 64 connected to the gripping electric gripper 11 is disposed at the bottom of the sliding block of the longitudinal electric cylinder 63. This design drives the gripping electric gripper 11 to move laterally through the operation of the transverse electric cylinders 61; drives the gripping electric gripper 11 to move longitudinally through the operation of the longitudinal electric cylinders 63; and drives the gripping electric gripper 11 to move vertically through the operation of the electric push rod 64, facilitating the gripping electric gripper 11 to grip the quartz tube.

[0025] Reference Figure 1 and Figure 8The base plate 1 has a mounting base 1001 on its top, and a mounting groove is provided on the top of the mounting base 1001. The conveyor belt 8 is located inside the mounting groove, and a drive assembly 12 for driving the conveyor belt 8 is provided on the mounting base 1001. This design facilitates the installation of the drive assembly 12 and the conveyor belt 8 through the mounting base 1001.

[0026] Reference Figure 2 and Figure 8 The drive assembly 12 includes a conveyor motor 121 mounted on the side wall of the mounting base 1001. A drive roller 122 located inside the mounting groove is mounted on the output shaft of the conveyor motor 121. Multiple driven rollers 123 located inside the mounting groove are located inside the mounting base 1001. The conveyor belt 8 is located on the side walls of the drive roller 122 and the driven rollers 123. This design uses the conveyor motor 121 in the drive assembly 12 to drive the drive roller 122 to rotate. The rotation of the drive roller 122, in conjunction with the driven rollers 123, drives the conveyor belt 8 to rotate, thus conveying the quartz tube on the positioning seat 9.

[0027] Reference Figure 1 and Figure 8 The positioning seat 9 has a positioning hole 91 on the side away from the conveyor belt 8, which matches the quartz tube. The positioning seat 9 and the conveyor belt 8 are made of the same material and are integrally connected. This design facilitates the positioning of the quartz tube through the positioning hole 91; the positioning hole 91 and the quartz tube are connected by an interference fit.

[0028] Reference Figures 1-8 As an embodiment of this utility model: when it is necessary to dry the quartz tube, the worker places the undried quartz tube on one of the positioning seats 9 symmetrically arranged on the conveyor belt 8, while the other positioning seat 9 is reserved for placing the dried quartz tube.

[0029] The drive motor 121 in the drive assembly 12 drives the active roller 122 to rotate. The rotation of the active roller 122, in conjunction with the driven roller 123, drives the conveyor belt 8 to rotate. The conveyor belt 8 drives the quartz tube on the positioning seat 9 to move closer to the positioning disk 4. The transverse electric cylinder 61 in the gripping assembly 6 drives the gripping electric gripper 11 to move laterally. The longitudinal electric cylinder 63 drives the gripping electric gripper 11 to move longitudinally. The electric push rod 64 drives the gripping electric gripper 11 to move vertically, so that the gripping electric gripper 11 can grab the undried quartz tube on the positioning seat 9 and clamp it at the positioning electric gripper 5 on the positioning disk 4. Then, the drive motor 2 drives the positioning disk 4 to rotate. Then, the above operation is repeated to grab the undried quartz tube on the positioning seat 9 and clamp it at the positioning electric gripper 5 on the positioning disk 4, thus completing the loading operation.

[0030] After the material is fed, the hot air blower 34 in the air supply assembly 3 operates, and the air supply pipe 35 provides hot air to the first hollow annular plate 32. The hot air is sent to the inside of the second hollow annular plate 36 through the connecting pipe 33. Finally, the quartz tube held by the positioning electric gripper 5 is dried along the annular groove 37 and the drying hole 42. Since the drying hole 42 is located at the bottom of the quartz tube, it is convenient for the gas after the quartz tube is dried to flow upward along the inner wall of the quartz tube, which speeds up the drying speed of the inner wall of the quartz tube. At the same time, the positioning plate 4 drives the quartz tube to rotate, which speeds up the drying speed of the outer wall of the quartz tube.

[0031] After drying, the gripping component 6 drives the electric gripper 11 to remove one of the dried quartz tubes from the positioning plate 4 and place it on one of the symmetrically arranged positioning seats 9 on the conveyor belt 8. Then, the undried quartz tube is gripped from the other symmetrically arranged positioning seat 9 and placed on the positioning plate 4. Next, the drive motor 2 drives the positioning plate 4 to rotate, ensuring that the dried quartz tube on the positioning plate 4 is directly below the electric gripper 11. This process is repeated, with the gripping component 6 driving the electric gripper 11 to complete the replacement operation of the quartz tubes on the positioning plate 4. Because the positioning seats 9 are symmetrically arranged on the conveyor belt 8, one positioning seat 9 can transport and place the undried quartz tube, while the other positioning seat 9 can transport and place the dried quartz tube. This reduces the moving distance of the electric gripper 11 during material change, facilitates the material change operation, saves material change time, and improves drying efficiency.

[0032] When the undried quartz tube is removed from the positioning seat 9, the empty space on the positioning seat 9 moves with the conveyor belt 8 to the side away from the positioning plate 4 for replenishment. At the same time, the dried quartz tube on the positioning seat 9 moves with the conveyor belt 8 to the side away from the positioning plate 4 for removal, which facilitates subsequent material replacement operations.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
