Description

A loading device and method for quartz glass tube and rod parent material

Technical Field

The invention relates to the technical field of quartz glass tube and rod production, and in particular to a loading device and method for a quartz glass tube and rod mother material.

Background Art

Compared with quartz glass products for ordinary light sources, existing quartz glass tubes and rods such as semiconductors and optical fibers have high purity requirements, but the demand is small and the specifications are diverse. The product outer diameter and wall thickness specifications have a wide range. In order to meet market demand, a production system that does not carry out continuous production and requires less metal pollution and can produce quartz glass tubes and rods of various specifications is used for production. This method uses the existing formed quartz glass tube and rod raw materials. When this method is used, the problem of transporting and fixing the quartz glass tube and rod mother material will arise. The mother material fixing method currently used is: the mother material fixing device is a three-claw or four-claw chuck, and the mother material is fixed through the center of the chuck. Because the weight of the mother material is generally greater than 40kg, it requires multiple people to install, one person fixes the chuck, and multiple people lift the mother material. The installation time usually takes about 2 hours. After the mother material is fixed, because it is fixed at a single point, the mother material will be tilted, and the problem of large deviation from the center of the furnace body is basically impossible to adjust. Due to the high temperature in the workshop, the installers sweat a lot, which will drip on the surface of the mother material and pollute the surface.

In the prior art, the transportation of quartz tube mother materials requires the participation of multiple people, which is time-consuming and labor-intensive, and also increases the probability of impurities being introduced; and during loading and transportation, the quartz tube mother material is fixed by a quartz pin and then lifted for transportation. The lifting method of one lifting point will cause the mother tube to swing freely during the lifting process of the mother tube, and when there is a strong vibration in the outside world, the mother tube may also swing. Therefore, during the transportation process, the speed is slow and the efficiency is low; during the placement of the mother tube, it is necessary to adjust the centering of the mother tube and the secondary processing device. When the measuring tool touches the mother tube during the centering, the mother tube will swing. Once the adjusted mother tube swings, the centering and subsequent hanging lines need to be readjusted, which affects the production efficiency and requires a high level of operation of the operator.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

The first aspect of the present invention is described with reference to FIG1 , which provides a loading device for a quartz glass tube rod mother material, comprising: a graphite tube 10, wherein a first concave hole and a second concave hole are concentrically sunken at the bottom, and a first outer pin hole is radially penetrated through the tube wall at the tube wall where the first concave hole is formed; the second concave hole is less deep than the first outer pin hole, and an inner thread is provided on the inner side; a graphite adjustment sleeve 20, which is provided with a base, a threaded portion provided on the base, and a through hole in the center that is consistent with the first concave hole; the threaded portion is screwed into the inner thread of the second concave hole; a graphite core rod 30, which penetrates the first concave hole and the through hole, and a second outer pin hole is provided at the upper portion corresponding to the first outer pin hole. An inner pin hole; a second inner pin hole is provided at the lower part of the graphite core rod; wherein, the first fixing pin 71 penetrates the first outer pin hole and the first inner pin hole to axially fix the graphite core rod 30 and the graphite tube 10; the lower end of the graphite core rod 30 is inserted into the insertion hole formed at the top of the quartz glass tube rod mother material 40, and the second fixing pin 72 penetrates the second outer pin hole and the second inner pin hole formed on the side wall of the quartz glass tube rod mother material 40 in the insertion hole to axially fix the graphite core rod 30 and the quartz glass tube rod mother material 40; the graphite adjustment sleeve 20 rotates in the second concave hole so that the base abuts against the upper end surface of the quartz glass tube rod mother material 40 and is tightened. Through the assembly of the above-mentioned graphite tube 10, graphite adjustment sleeve 20 and graphite core rod 30, a set of loading graphite components is formed to load and fix the quartz glass tube rod mother material, realize the rapid loading of the mother material, and facilitate the subsequent hoisting, transportation and secondary processing.

In the above embodiment, the graphite tube 10, the graphite adjustment sleeve 20, the graphite core rod 30 and the quartz glass tube rod mother material 40 are assembled into a whole by the first fixing pin 71 and the second fixing pin 72, respectively. The installation time can be saved by the simple and fast connection method of the fixing pins. In actual operation, the loading device of the present invention is used to install the mother material, and the installation rate is increased by 400%. The detachable installation method increases the flexibility of the equipment. At the same time, different graphite core rods 30 are selected according to the specifications of the quartz glass tube rod mother material 40. The selection basis is that the graphite core rod 30 can be inserted into the interior of the quartz glass tube rod mother material 40, and the gap is 0.5-3mm. If the gap is too small, it will make it difficult to insert during installation and delay the installation time; if the gap is too large, it will provide space for the shaking of the mother material.

In this embodiment, the first and second fixing pins are cylindrical, and their length is equal to the outer diameter of the graphite tube 10. The diameter of their cross-sections has certain requirements. Different diameters are selected according to the weight of the parent material to meet the gravity requirements and prevent breakage. The diameter of the pin hole is consistent with the diameter of the fixing pin, which is convenient for insertion and extraction. For example, in actual operation, when the weight of the parent material is 100-200 kg, the diameter of the fixing pin is 20-30 mm; when the weight of the parent material is 200-300 kg, the diameter of the fixing pin is 30-50 mm.

In this embodiment, the installation directions of the first fixing pin 71 and the second fixing pin 72 can be set in parallel or at an angle, such as 90°. The angle setting ensures the force balance between the graphite core rod 30 and the graphite tube 10, and at the same time ensures the force balance between the mother material and the graphite core rod 30. Among them, a first fixing pin 71 can be used to penetrate the graphite rod 10 and the graphite core rod 30 in sequence; a second fixing pin 71 can also be used to penetrate the mother material and the graphite core rod 30 in sequence. Not only can the increase in the hoisting weight be achieved by using fixing pins of different diameters, but also by increasing the number of fixing pins, so as to better adapt to the transportation of heavier mother materials. For example, the first fixing pin 71 is converted from one to three, four, six, etc., and according to the different numbers, the cross section of the graphite tube 10 is evenly distributed into different units, and a unit fixing pin is set on each unit. Corresponding unit pin holes are set on the graphite tube 10 and the graphite core rod 30. At this time, the graphite core rod 30 is hollow, and each unit fixing pin is inserted from the unit pin hole on the outside of the graphite tube 10 through the unit pin hole of the graphite core rod 30 to reach the hollow part inside the graphite core rod 30, without having to penetrate the entire graphite core rod 30. Multiple unit fixing pins are located on the same horizontal plane, which increases the fixing points and ensures the load-bearing capacity. Similarly, the second fixing pin can also be converted into multiple unit fixing pins in the same way. On the basis of ensuring the balance of force, the load-bearing capacity is also increased, which increases the flexibility of the equipment.

In the above embodiment, the graphite adjustment sleeve 20 adjusts the height position of the base by rotating in the second concave hole, so that the base abuts against the upper end surface of the quartz glass tube rod mother material 40 and is tightly assembled to fill the gap between the quartz glass tube rod mother material 40. The threaded portion of the graphite adjustment sleeve 20 rotates in the second concave hole to adjust the distance between the base and the mother material until they abut. In actual operation, due to errors in processing dimensions and different specifications, a gap will appear between the quartz glass tube rod mother material 40 and the graphite rod 10 after the two are connected by the graphite core rod 30. The height of the gap directly causes the mother material to swing around the fixed pin. At this time, the graphite adjustment sleeve 20 needs to be adjusted. By rotating the threaded portion in the graphite tube 10, the descending height of the threaded portion is adjusted so that the base at the lower end of the threaded portion abuts against the end surface of the mother material, thereby filling the distance between the two, removing the gap, and preventing the mother material from shaking.

In this embodiment, the base is a protruding portion below the threaded portion, and its width is not less than the width of the end face of the quartz glass tube rod parent material 40; the base abuts the end face of the quartz glass tube rod parent material 40. The setting of the base is to further increase the stability of the connection, by increasing the contact area below the connection portion and increasing the area abutting the end face of the parent material, thereby increasing the stability of the connection. As shown in Figure 1, the design of the base of the graphite adjustment sleeve 20 enables a seamless connection between the graphite rod 10 and the parent material 40, improves integration, and at the same time ensures the stability and movement consistency of the parent material.

In the above embodiment, a hoisting assembly is provided on the top of the graphite tube 10 for hoisting and transporting the quartz glass tube rod mother material 40. By connecting the graphite loading assembly of the mother material with the crane, the hoisting assembly is designed to increase the speed of hoisting and improve the working efficiency.

In the above embodiment, the hoisting assembly includes: a hoisting seat 50, a horizontally arranged spherical bearing 51 is embedded in the center, and a mounting hole is formed at the center of the spherical bearing 51; a connecting rod 60, the top end of which is mounted in the mounting hole, and the bottom end is mounted on the top end of the graphite tube 10, and is used to connect the loading device and the hoisting seat 50 to realize the loading and transportation of the quartz glass tube and rod mother material 40. The hoisting seat 50, the connecting rod 60, the graphite tube 10, the graphite core rod 30 and the graphite adjustment sleeve 20 connected in sequence form a set of mother material loading and transportation equipment, which can be quickly installed and connected with the mother material, so that the mother material can be quickly transported by the crane, greatly improving the installation efficiency and transportation efficiency.

In the above embodiment, a holder 61 is provided at the top of the connecting rod 60, and the bottom of the connecting rod 60 is inserted into the mounting hole. The holder 61 is positioned in the spherical bearing 51 to fix the connecting rod 60 on the hanging seat 50. The setting of the holder 61 is to fix the connecting rod 60 on the spherical bearing 51. The spherical bearing 51 is embedded in the hanging seat 50. The connecting rod 60 and the loading graphite assembly and the parent material form a loading whole. During the transportation process, they will receive forces from all parties, such as the inertia caused by the driving movement, which will cause the parent material to shake. The spherical bearing 51 can withstand radial force, axial force or the combined force of radial and axial forces, and always keep the center of gravity of the parent material stable. The setting of the spherical bearing 51 no longer requires the speed requirement when the parent material is transported, which can increase the vehicle speed and improve the transportation speed.

In this embodiment, the specific structure of the spherical bearing 51 is shown in FIG2. The spherical bearing 51 is composed of a bearing outer ring 511 and a bearing inner ring 512. The inner surface of the bearing outer ring 512 is a concave arc surface, and the outer surface of the bearing inner ring 511 is a convex arc surface. The concave arc surface and the convex arc surface match each other. The bearing inner ring 511 can rotate in multiple directions inside the bearing outer ring 512. A bearing hole is provided in the middle of the hanging seat 50, and a circle of grooves is provided on the side wall of the bearing hole. The bearing outer ring 511 is installed and fixed inside the groove, and the spherical bearing 51 is embedded in the hanging seat 50. A connecting hole 513 is provided in the middle of the bearing inner ring 511. The size of the connecting hole 513 is equal to the diameter of the connecting rod 60. After the connecting rod 60 passes through the connecting hole 513, the clamping seat 61 at the top of the connecting rod 60 is just clamped at the edge of the bearing inner ring 511, and the connecting rod 60 and the connected graphite loading device are hung on the edge of the bearing inner ring 511 by their own gravity.

In the above embodiment, the bottom end of the connecting rod 60 is provided with an external thread, which is connected and fixed with the internal thread at the top end of the graphite tube 10. Other fixing methods can also be used to connect the connecting rod 60 and the graphite tube 10, such as bolt fixing, such as stud fixing, etc., as long as it is quick to install and the connection is stable.

In this embodiment, the connecting rod 60 can be made of a stainless steel pipe with a through hole in the middle, which can meet the connection strength requirements while reducing the weight. The entire loading device can be designed to be hollow or hollow in the technology of reducing the weight of the equipment. The weight reduction of the loading device can save power and energy, and is energy-saving and environmentally friendly. On the basis of meeting the connection strength requirements, connecting rods made of other materials can also be used.

In the above embodiment, the lifting seat 50 is provided with lifting buckles 52 around it for use in crane lifting. In order to facilitate lifting, the lifting buckles 52 are provided on the lifting seat 50, and the crane can be quickly hinged and fixed. In actual operation, the lifting buckles 52 can be D-shaped buckles and installed on both sides or around the lifting seat 50. The lifting seat 50 and the lifting buckles 52 are both made of stainless steel to increase the safety of lifting.

In the present invention, the mother material is loaded onto the graphite core rod and other graphite components, and combined with the lifting seat with a joint bearing to form a complete lifting and transportation equipment. This equipment realizes the function of adjusting the center of gravity of the mother material, so that during the placement of the mother material, the mother material with self-adjusting center of gravity can be directly placed at the secondary processing location without manual participation in the center of gravity adjustment, thus avoiding contamination of the surface of the mother material by the center of gravity adjustment equipment or personnel.

The loading device of the present invention uses graphite with a density of 1.5-2g/cm3 or ^more for preparation. The use of high-purity graphite achieves the tensile strength required for hoisting in the face of different specifications of the weight of the base material, and is also to adapt to the working environment of the secondary processing of the base material. In actual operation, after the base material is transported to the secondary processing site for placement, the loading device is not disassembled, but is subjected to secondary processing along with the base material, thus saving the time for reinstalling the loading device after processing. Usually, the working environment of the secondary processing is carried out at a high temperature of 1000-1500°. If other materials are used, impurities will volatilize at this high temperature, thereby affecting the purity of the base material. In order to ensure purity, the position in the loading device connected to the base material can also be made of quartz material. However, the quartz material will be slightly dissolved at this high temperature for a long time, thereby affecting the hoisting; it will also adhere to the base material, affecting the quality of the base material.

In the prior art, when the mother material is hoisted for operation, the mother material will shake and swing too much or too little. In order to prevent the hoisted mother material from swinging and shifting the center of gravity, the present invention uses a graphite adjustment sleeve to fix the mother material after the mother material is fixed to the graphite core rod with a fixing pin, so as to prevent the mother material from swinging around the fixing pin; at the same time, a joint bearing is arranged on the hoisting seat, which can withstand radial force, axial force or combined force of radial and axial forces at the same time, so that the loading device and the mother material can automatically adjust the center of gravity of the mother material due to their own gravity, and always keep the center of gravity stable, which saves the operation of adjusting the center of gravity when the mother material is placed for secondary processing, can greatly improve the transportation speed, and improve the operation efficiency.

When assembling the loading device and the parent material, manual assembly can be performed at room temperature, or automated assembly can be performed by machinery to ensure the cleanliness of the loading device and avoid the introduction of impurities.

During the secondary processing of the parent material, the loading graphite components made of high-purity graphite do not need to be removed, and no impurities will be introduced even in a high-temperature processing environment. During the entire processing process, the operation process is reduced, and the next process can be directly hoisted after processing, saving time and increasing the speed of operation.

During the entire process of loading and transporting the quartz glass tube and rod mother material, there is no need for personnel to contact and assemble the quartz glass tube and rod mother material; during the placement of the quartz glass tube and rod mother material, there is no need to manually adjust the center of gravity of the quartz glass tube and rod mother material; the entire process is automated, avoiding the introduction of impurities (dust, oil stains, sweat stains, etc.) on the surface of the quartz glass tube and rod mother material, and ensuring the purity of the quartz glass tube and rod mother material.
