Automatic bending equipment based on quartz tube / rod and processing method thereof

Abstract

The application belongs to the technical field of quartz processing, and particularly relates to an automatic bending equipment based on a quartz tube / bar and a processing method thereof. The equipment comprises a rack, a clamp assembly for clamping the quartz tube / bar, a spray gun assembly for heating a bending area of the quartz tube / bar on the clamp assembly, a rotary driving assembly for driving the clamp assembly to rotate, a bending assembly for providing a fulcrum for bending of the quartz tube / bar when the rotary driving assembly drives the clamp assembly to rotate, and a control unit. The rotary driving assembly drives the clamp assembly to rotate in a constant force mode through friction wheel transmission. The friction wheel driving mode can avoid direct action of motor output force on the quartz tube / bar, and can ensure constant torque output through friction transmission, effectively preventing the quartz tube / bar from being broken due to improper parameters during bending. When the quartz tube / bar type, such as diameter and wall thickness, is changed, a large amount of debugging is not needed.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of quartz processing, and particularly relates to an automatic bending equipment based on a quartz tube / rod and a processing method thereof. BACKGROUND

[0002] With the rapid development of the IC industry, the semiconductor equipment manufacturing industry is gradually maturing, and quartz glass products are important components of semiconductor equipment, and the demand is increasing. Because quartz glass has a series of characteristics such as high hardness, high purity, low thermal expansion coefficient, and electrical insulation, the processing technology is very strict, especially the bending process of quartz tube rods, which is currently mostly completed by manual work with some simple mechanical jigs. The product quality is unstable, the pass rate and processing efficiency are generally low, and at the same time, there are many types of quartz tube rods in semiconductor equipment, with various diameters, wall thicknesses, lengths, etc. Changes in these parameters will require corresponding adjustments to the softening time and bending speed of the quartz tube rod bending process, which is labor-intensive and has high debugging costs. Therefore, there is an urgent need for a device that can automatically bend quartz tube rods.

[0003] For example, patent publication CN 113336428 A discloses a "quartz tube bending device and method", which is composed of a machine base, a pressure stabilizing mechanism, and a tube bending driving mechanism. One end of the quartz tube is sealed with a rubber plug, and compressed gas is introduced into the other end to ensure internal pressure stabilization. The quartz tube is fixed on the machine base clamp, and the softening of the quartz tube is heated by a spray gun. The piston cylinder clamps one end of the quartz tube and rotates with the servo motor to achieve semi-automatic bending of the quartz tube. This scheme can achieve simple quartz tube bending to some extent, but the device is semi-automatic, the size of the spray gun flame, the distance from the quartz tube, and the softening position will change, and the device clamp is single and fixed at a distance from the bending device. It can only complete bending work with a bending radius of less than 180 degrees, and has great limitations. It is not suitable for mass production, and the invention fixes one end of the quartz tube and clamps the other end for bending. There is no deformation allowance left for the quartz tube, which poses a risk of quartz tube rupture during stretching. The existing patent uses a motor output shaft to hard contact with the quartz tube, and controls the bending angle of the tube through a servo motor encoder. This method has the disadvantage of needing to be adjusted multiple times to determine the optimal bending speed, and when the flame size changes, it needs to be adjusted again, which can easily cause the quartz tube to break during bending.

[0082] and control unit 600, used to control the operating status of spray gun assembly 300 and rotary drive assembly 400;

[0083] The rotary drive assembly 400 drives the clamp assembly 200 to rotate by constant force through friction wheel transmission.

[0084] In the technical solution, based on the existing technical solution of directly driving the clamp assembly 200 to rotate by the motor 410, the design scheme of driving the clamp assembly 200 by the friction wheel transmission mode can eliminate the influence of the output of the motor 410, ensure the constant torque output in the bending process, and only when the softening degree of the quartz tube / rod 10 reaches the level that can be bent by the torque, the quartz tube / rod 10 can be bent, so that the device does not have the possibility of causing the quartz tube / rod 10 to break. This will improve the efficiency and quality of the quartz tube / rod 10 bending process, make it have higher accuracy, consistency, reduce deformation and damage, and save energy consumption.

[0085] In the embodiment, the rack 100 serves as a carrier to facilitate the assembly of various components.

The clamp assembly 200, the spray gun assembly 300, the rotary drive assembly 400, and the bending assembly 500 can be integrated on the installation bottom plate 110. The components are integrated on the installation bottom plate 110, and then the installation bottom plate 110 is fixed on the rack 100, thereby effectively improving the installation efficiency of the whole device.

[0086] Embodiment 2:

[0087] The embodiment provides an automatic bending device based on a quartz tube / rod 10. In addition to the technical solutions of the above embodiments, the device has the following technical features.

[0088] As shown in Figure 2 and Figure 3 In the embodiment, the rotary drive assembly 400 is installed inside the rack 100, that is, below the workbench, to play a dustproof and protective role. Specifically, the rotary drive assembly 400 includes:

[0089] The motor 410 is fixed on the bottom of the installation bottom plate 110 through the motor 410 mounting frame in the vertical direction;

[0090] The speed reducer 430 is arranged on the output shaft of the motor 410 and is used for speed reduction processing of the motor 410;

[0091] The driving friction wheel 440 is arranged on the output shaft of the speed reducer 430;

[0092] The driven friction wheel 450 is in contact with the driving friction wheel 440;

[0093] The clamp assembly 200 includes:

[0094] The rotary base 210;

[0095] A transmission shaft 220 is arranged on the mounting base 110 in a vertical direction through a bearing seat, and the upper and lower ends thereof pass through the mounting base 110, the rotating base 210 is mounted on the upper end of the transmission shaft 220, and the driven friction wheel 450 is mounted on the lower end of the transmission shaft 220;

[0096] A clamp 230 is arranged on the rotating base 210 and used for clamping the quartz tube / rod 10.

[0097] Under the control of the control unit 600, the driving friction wheel 440 drives the driven friction wheel 450 to rotate at a constant force, and drives the rotating base 210 and the clamp 230 thereon to rotate.

[0098] In the technical solution, the operator starts the motor 410 by using the control unit 600, controls the rotating speed and direction of the motor 410, the rotating power of the motor 410 is transmitted to the speed reducer 430 through the output shaft, the speed reducer 430 converts the high-speed low-torque rotation into low-speed high-torque output, the output shaft of the speed reducer 430 is connected to the driving friction wheel 440, the rotating power of the driving friction wheel 440 is transmitted to the driven friction wheel 450 through friction, among which the driving friction wheel 440 drives the driven friction wheel 450 to rotate at a constant force, so that the transmission shaft 220 and the rotating base 210 and the clamp 230 thereon rotate, and the clamped quartz tube / rod 10 is driven to rotate and is bent under the extrusion of the bending assembly 500.

[0099] The pressing force between the driving friction wheel 440 and the driven friction wheel 450 can be adjusted by arranging the motor mounting seat 420 to be movable.

[0100] Embodiment 3

[0101] The embodiment provides an automatic bending equipment based on a quartz tube / rod 10, in addition to the technical solutions of the above embodiments, and has the following technical features.

[0102] As shown in Figure 2 , Figure 4 In the embodiment, the clamp assembly 200 further comprises:

[0103] The clamp sliding seat 240 is arranged on the rotating base 210 in a sliding manner along the direction of approaching or moving away from the bending assembly 500 with the bending assembly 500 as a reference point, and the clamp 230 is arranged on the clamp sliding seat 240.

[0104] In the technical solution, the clamp 230 is arranged on the clamp sliding seat 240, so that the clamp 230 can move along the Y-axis direction, that is, after the clamp 230 clamps the quartz tube / rod 10, the position of the quartz tube / rod 10 can be adjusted, so as to change the bending point of the quartz tube / rod 10.

[0105] Specifically, a groove is formed in the rotating base 210, a horizontal lead screw is arranged in the groove, the clamp sliding seat 240 is arranged on the nut seat of the lead screw, and the clamp sliding seat 240 can be moved by rotating the lead screw. For the clamp sliding seat 240, it only plays a fine tuning role, that is, it is used to fine tune the position of the quartz tube / rod 10, so one end of the lead screw protrudes out of the groove and penetrates through the rotating base 210, and a nut for limiting the rotation of the lead screw is further arranged on the lead screw. By loosening or tightening the nut, manual rotation of the lead screw can be realized.

[0106] In the embodiment, the clamp 230 comprises:

[0107] The clamping seat 231 is arranged on the clamp sliding seat 240, and the first clamping ear plate 2311 is arranged on the clamping seat 231.

[0108] The clamping side plate 232 is slidably arranged on the clamping seat 231, and the second clamping ear plate 2321 opposite to the first clamping ear plate 2311 is arranged on the clamping side plate 232. The interval between the first clamping ear plate 2311 and the second clamping ear plate 2321 forms a cavity for clamping the quartz tube / rod 10.

[0109] The first adjusting member 233 is connected to the clamping side plate 232 and the clamping seat 231, and is used to adjust the position of the clamping side plate 232 to change the interval between the first clamping ear plate 2311 and the second clamping ear plate 2321.

[0110] In the technical solution, the structure of the clamp 230 has the advantages of flexibility, adjustability and stability in clamping the quartz tube / rod 10. It can adapt to quartz tubes / rods 10 of different sizes and shapes, and meet specific bending requirements by adjusting the position and interval of the clamping side plate 232. This design simplifies the operation and adjustment process, improves the clamping precision and stability, and provides reliable support for the bending processing of the quartz tube / rod 10.

[0111] Specifically, the interval between the first clamping lug 2311 and the second clamping lug 2321 on the clamping seat 231 forms a cavity for clamping the quartz tube / rod 10. This design can flexibly clamp quartz tubes / rods 10 of different sizes and shapes, improving the adaptability and flexibility of clamping. The first adjusting piece 233 of the clamp 230 connects the clamping side plate 232 and the clamping seat 231, used to adjust the position of the clamping side plate 232. By adjusting the first adjusting piece 233, the position of the clamping side plate 232 can be changed, thereby adjusting the distance between the first clamping lug 2311 and the second clamping lug 2321. This allows the operator to flexibly adjust the position of the clamping point and the clamping force according to specific needs to adapt to different bending requirements and the size of the quartz tube / rod 10.

[0112] In this embodiment, the optimized clamp assembly 200 further comprises a limiting jig 250, which is detachably arranged on the rotating base 210.

[0113] The bending device further comprises a sensor 700 arranged on the workbench.

[0114] During the process of driving the motor 410 to rotate and driving the rotating base 210 to rotate by the control unit 600, the sensor 700 is used to detect the position of the limiting jig 250 and send the detected signal to the control unit 600. After the control unit 600 receives the signal sent by the sensor 700, the motor 410 stops running.

[0115] In this technical solution, by setting the limiting jig 250 and the sensor 700, the control unit 600 can accurately control the rotation angle of the rotating base 210 in combination with the two, thereby realizing the bending of the quartz tube / rod 10.

[0116] The limiting jig 250 is replaceably arranged. When it is needed to bend the quartz tube / rod 10 into different angles, it can be realized by replacing the limiting jig 250 of different angles, which is very convenient. For example, when bending 180°, the limiting jig 250 is a straight rod-shaped structure, which can be detected by the sensor 700 after rotating 180°. When bending 90°, the limiting jig 250 is an arc-shaped structure bent 90°, which can be detected by the sensor 700 after rotating 90°. This design effectively improves the bending efficiency of the quartz tube / rod 10.

[0117] Embodiment 4:

[0118] The embodiment provides an automatic bending device based on a quartz tube / rod 10, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0119] As Figure 2 andFigure 4 As shown in the present embodiment, the bending assembly 500 includes:

[0120] A stop post base 510 is provided on the workbench;

[0121] A stop post sliding seat 520 is slidably arranged on the stop post base 510 along the X-axis direction;

[0122] A stop post 530 is arranged on the sliding seat, which provides a fulcrum for the bending of the quartz tube / rod 10 when the rotary drive assembly 400 drives the clamp assembly 200 to rotate;

[0123] And a second adjusting member 540 is connected to the stop post base 510 and the stop post sliding seat 520, which is used to adjust the position of the stop post sliding seat 520 to change the position of the stop post 530.

[0124] In the present technical solution, the structure design of the above-mentioned bending assembly 500 can realize the precise bending of the quartz tube / rod 10, and has the advantages of adjustability, stability and simplification of operation. It provides a fulcrum and control, so that the quartz tube / rod 10 can remain stable during bending, and the bending angle can be flexibly controlled by adjusting the position of the stop post sliding seat 520. This design makes the bending process more controllable and accurate, and provides reliable support for the processing of the quartz tube / rod 10.

[0125] As shown in Figure 5 and Figure 6 The limit jig 250 chamber provides large-angle adjustment, such as 90°, 180°, etc. For other angles, such as 30°, 45°, 60°, etc., the position of the stop post sliding seat 520 can be adjusted to achieve.

[0126] The main function of the bending assembly 500 is to provide a fulcrum for the quartz tube / rod 10, so that it can be bent under the action of the rotary drive assembly 400. The stop post 530 is arranged on the stop post sliding seat 520, and when the clamp assembly 200 rotates, the stop post 530 acts as a fulcrum, so that the quartz tube / rod 10 can remain in a fixed position during bending, achieving precise bending.

[0127] The second adjusting member 540 is connected to the base and the stop post sliding seat 520, which is used to adjust the position of the stop post sliding seat 520. By adjusting the second adjusting member 540, the position of the stop post sliding seat 520 relative to the stop post base 510 can be changed, thereby adjusting the position of the stop post 530. In this way, the distance and angle between the clamp assembly 200 and the stop post 530 can be flexibly controlled, and the position and angle of the bent quartz tube / rod 10 can be adjusted.

[0128] The structural design of the stop column base 510 and the stop column sliding seat 520 provides stable support and control. During the bending process, the stop column 530 acts as a fulcrum, ensuring that the quartz tube / rod 10 has good support and control, making the bending process more stable and controllable, reducing the risk of deformation and loss of control.

[0129] By sliding the stop column sliding seat 520 and adjusting the second adjusting member 540, the adjustment of the bending assembly 500 can be achieved. The operator can flexibly adjust the position and angle between the clamp assembly 200 and the stop column 530 according to specific needs to meet specific bending requirements. This simplifies the operation process and improves the efficiency and accuracy of adjustment.

[0130] In this embodiment, the stop column base 510 is provided with a first scale line 511, and the stop column sliding seat 520 is provided with a second scale line 521 corresponding to the first scale line 511. The first scale line 511 and the second scale line 521 cooperate to accurately calculate the position of the stop column sliding seat 520.

[0131] In this technical solution, the position of the stop column sliding seat 520 is determined by using scale lines, which can achieve high accuracy. The scale lines provide visual reference marks, allowing the operator to accurately read and adjust the position of the stop column sliding seat 520. This accuracy is crucial for precise bending operations, especially in high-precision machining processes, ensuring the accuracy and consistency of bending.

[0132] This setting has the advantages of high accuracy, easy operation, good repeatability, and fast adjustment, and can also provide accurate positioning and adjustment reference, which helps to achieve precise and repeatable bending operations.

[0138] A spray gun 330 is arranged on the fixed seat 320 of the spray gun 330, which has an air inlet port 331 and at least one flame outlet port 332, and the flame outlet port 332 is opposite the bending area of the quartz tube / rod 10 on the clamp assembly 200, specifically, the spray gun 330 has two flame outlet ports 332 and is horn-shaped, distributed on both sides of the quartz tube / rod 10.

[0139] And two gas supply branch pipes 340 are provided, and both are connected to the air inlet port 331 of the spray gun 330 to respectively provide hydrogen and oxygen for the spray gun 330; the two gas supply branch pipes 340 are both provided with a gas valve 350.

[0140] Among them, the three-axis adjustable platform 310 and the gas valve 350 are controlled by the control unit 600.

[0141] In the technical solution, the opening size of the gas valve 350 is controlled by the control unit 600, so as to adjust the size of the flame of the spray gun 330, and then the spray gun 330 is moved by controlling the three-axis adjustable platform 310, so as to change the position and angle of the spray gun 330, thereby realizing the heating of the quartz tube / rod 10.

[0142] Through the design of the three-axis adjustable platform 310, the spray gun assembly 300 can move and adjust in the horizontal X-axis, Y-axis and vertical Z-axis directions. This multi-axis adjustment capability enables the operator to accurately control the position and angle of the spray gun 330 to adapt to different work requirements and workpiece shapes. By adjusting the position of the spray gun 330 in three directions, the operation of the flame can be realized.

[0143] In this embodiment, the three-axis adjustable platform 310 is optimized and includes:

[0144] A first seat body 311 is arranged on the workbench;

[0145] A second seat body 312 is slidably arranged on the first seat body 311 along the X-axis direction;

[0146] A first power part 313 is used to drive the second seat body 312 to slide on the first seat body 311;

[0147] A third seat body 314 is slidably arranged on the second seat body 312 along the Y-axis direction;

[0148] A second power part 315 is used to drive the third seat body 314 to slide on the second seat body 312;

[0150] And a third power part 317 is used to drive the fourth seat body 316 to slide on the third seat body 314.

[0151] In the technical solution, for the three-axis adjustable platform 310, since it only adjusts in a small range, a pneumatic cylinder can be used as the power. Specifically, when the position of the spray gun 330 needs to be adjusted, the control unit 600 controls the first power part 313, the second power part 315, or the third power part 317, or controls all of them at the same time, so that the fourth seat body 316 moves. After reaching the corresponding position, the controller controls the power parts to stop working.

[0152] Embodiment 6:

[0153] The embodiment provides a processing method of the automatic bending equipment based on the quartz tube / rod 10 in any one of the above embodiments, and the processing method comprises the following steps:

[0154] Loading of the quartz tube / rod 10:

[0155] According to the bending requirement of the quartz tube / rod 10, the limiting jig 250 with different angles is replaced, then the quartz tube / rod 10 is placed on the clamping seat 231, then the first adjusting part 233 is adjusted, so that the first clamping ear plate 2311 and the second clamping ear plate 2321 are close to each other and the quartz tube / rod 10 is clamped; then the spray gun assembly 300 and the bending assembly 500 are adjusted to appropriate positions; specifically, the second adjusting part 540 is loosened, the blocking column sliding seat 520 is loosened, then the blocking column sliding seat 520 is moved, the position of the blocking column sliding seat 520 is accurately controlled according to the combination of the first scale line 511 and the second scale line 521, then the second adjusting part 540 is tightened, so that the blocking column sliding seat 520 cannot be moved; then the controller controls the three-axis adjustable platform 310 to move, so that the spray flame port 332 on the spray gun 330 is opposite to the bending area of the quartz tube / rod 10.

[0156] Heating of the quartz tube / rod 10:

[0157] The spray gun assembly 300 is controlled by the control unit 600, so that the spray gun assembly 300 sprays flame to the bending area of the quartz tube / rod 10.

[0158] Bending of the quartz tube / rod 10:

[0159] When the quartz tube / rod 10 is gradually heated and softened, the control unit 600 simultaneously controls the motor 410 to rotate. In the initial stage, since the quartz tube / rod 10 is not softened, the driving friction wheel 440 cannot drive the driven friction wheel 450 to rotate. After the quartz tube / rod 10 is softened, the driving friction wheel 440 acts on the driven friction wheel 450, so that the driven friction wheel 450 rotates, and the driven friction wheel 450 drives the rotary base 210 and the clamp 230 on the rotary base 210 to rotate, so that the quartz tube / rod 10 on the clamp 230 rotates and is bent under the blocking of the blocking column 530 on the bending assembly 500. After the rotary base 210 rotates to the position where the mold is detected by the sensor 700, the control unit 600 controls the motor 410 to stop running, and controls the spray gun assembly 300 to stop heating the quartz tube / rod 10.

[0160] The quartz tube / rod 10 is fed into the clamp assembly 200.

[0161] After the quartz tube / rod 10 is cooled, the bent product is taken out, and then the reset button is pressed. The control unit 600 drives the motor 410 to reverse, so that the clamp assembly 200 is reset. The above operation is repeated, so that the quartz tube / rod 10 is automatically bent.

The above specific embodiments are only illustrative, but not restrictive. Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims, and all the forms belong to the protection scope of the present application.
