Description

Technical Field

[0001] This invention relates to the field of semiconductor processing technology, and more specifically, to a quartz tube processing apparatus and method. Background Technology

[0002] Currently, quartz tube processing requires heat treatment to meet the requirements of various quartz tube shapes. To facilitate processing, a processing fixture is often used to mount the quartz tube for heat treatment. However, existing fixtures are only suitable for one type of product. When processing quartz tubes with different shapes and structures, a new fixture design is required, resulting in numerous product assembly and adjustment operations. Chinese Patent Application No. 201721825690 X discloses a quartz tube bending auxiliary fixture that uses a helical push rod to convert rotational motion into a smooth forward linear motion for clamping and bending quartz tubes. However, it can only perform processing operations at a single bending position and cannot meet the processing requirements of various quartz tube shapes. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a quartz tube processing apparatus and method, which can meet the processing requirements of various quartz tubes of different shapes, has good versatility, and is conducive to improving work efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quartz tube processing device, comprising a base plate, a head fixing block, a tail fixing block, and a positioning block. The head fixing block and the positioning block are both movably mounted on the base plate. A plurality of positioning blocks are disposed between the head fixing block and the tail fixing block. The head fixing block is provided with a positioning slot, and the tail fixing block is provided with a positioning insertion hole. The positioning block is provided with a support surface and a mating surface, which respectively support and mate the quartz tube for positioning.

[0005] Before heat treatment of the quartz tube, mark the heat treatment position on the quartz tube. Insert the head of the quartz tube into the positioning slot on the head fixing block, then heat treat and bend the quartz tube. After bending, support it on the support surface and position the quartz tube against the mating surface. Insert the tail of the quartz tube into the positioning hole. After cooling, remove the quartz tube to prepare for the processing of the next quartz tube.

[0006] Since both the head fixing block and the positioning block are movable and mounted on the base plate, their positions can be adjusted according to the size specifications of the quartz tube being processed, resulting in better matching and good versatility. The quartz tube processing device of this patent application can meet the processing requirements of various quartz tubes of different shapes, offering good versatility and improving work efficiency.

[0007] Preferably, the upper part of the head fixing block is connected to a positioning pressure block, and the positioning pressure block is provided with a C-shaped pressure groove, which presses on the quartz tube.

[0008] After the quartz tube head is inserted into the positioning slot, the positioning block is connected to the head fixing block. The C-shaped groove on the positioning block presses against the quartz tube to position the quartz tube and improve its stability.

[0009] Preferably, the positioning block is provided with a slot, which is inserted into the upper end of the head fixing block. Two locking points are provided on the inner wall of one side of the slot, and the two locking points are locked into the side wall of the positioning slot.

[0010] The positioning block is connected to the upper end of the head fixing block via a slot, making assembly and disassembly convenient. Two locking points on the positioning block engage with the side wall of the positioning slot, improving the reliability of the connection between the positioning block and the head fixing block.

[0011] Preferably, the support surface is inclined.

[0012] The support surface is tilted to ensure smooth contact between the quartz tube and the support surface, achieving reliable positioning.

[0013] Preferably, a support block is rotatably mounted on the positioning block, with the upper surface of the support block serving as the support surface. A push-pull block is mounted on the positioning block, and the push-pull block pushes the support block to rotate, thereby adjusting the tilt angle of the support surface.

[0014] The support surface is set on a rotatable support block. As the support block rotates, the tilt angle of the support surface can be adjusted to process quartz tubes of different shapes. The support block is rotated by a push-pull block, making operation convenient and reliable.

[0015] Preferably, the base plate is provided with guide grooves corresponding to the head fixing block and the positioning block, and guide blocks are provided at the lower ends of the head fixing block and the positioning block, with the guide blocks slidably connected to the guide grooves.

[0016] When the head fixing block and positioning block slide on the base plate, the guide block slides along the guide groove, which is smooth and reliable.

[0017] Preferably, bent load-bearing blocks are provided between the positioning blocks and between the positioning blocks and the tail fixing blocks. The bent load-bearing blocks are installed on the base plate, and an arc-shaped load-bearing surface is provided on the bent load-bearing blocks. The quartz tube is abutted against the arc-shaped load-bearing surface.

[0018] During the bending process of the quartz tube, the arc-shaped bearing surface on the bending bearing block plays a supporting and positioning role for the quartz tube, ensuring that the shape of the quartz tube at the bending position meets the requirements.

[0019] Preferably, the tail fixing block is lifted and mounted on the base plate, and a positioning spring is installed between the tail fixing block and the base plate.

[0020] Before inserting the tail end of the quartz tube into the positioning hole, press the tail fixing block downwards so that it is lower than the tail end of the quartz tube. Once the tail end of the quartz tube is aligned with the positioning hole, release the tail fixing block. Under the action of the positioning spring, the tail fixing block is pushed upwards, thus allowing the positioning hole to be inserted into the tail end of the quartz tube for positioning. The lifting and lowering mechanism of the tail fixing block prevents interference between the tail end of the quartz tube and the tail fixing block when the quartz tube is bent.

[0021] Preferably, a rotatable positioning clamping block is installed on the positioning block, and an arc-shaped clamping surface is provided on the positioning clamping block. The positioning clamping block rotates to clamp the arc-shaped clamping surface at the upper circumferential position of the quartz tube.

[0022] After one section of the quartz tube is bent, the positioning clamp is rotated so that the arc-shaped clamping surface on the positioning clamp is clamped onto the quartz tube, thereby positioning the quartz tube and improving its stability. This prevents the already bent section from being affected when bending the next section.

[0023] A method for processing quartz tubes, using a quartz tube processing device, includes the following steps: S1, adjusting the positions of the head fixing block and the positioning block according to the specifications of the quartz tube; S2, inserting the head of the quartz tube into the positioning slot and marking the heat processing position; S3, heat processing and bending the quartz tube, supporting it on the support surface after bending, and inserting the tail of the quartz tube into the positioning socket.

[0024] Both the head fixing block and the positioning block are movable and mounted on the base plate. Therefore, the position of the head fixing block and the positioning block can be adjusted according to the size and specifications of the quartz tube being processed to achieve better matching. It has good versatility and can meet the processing requirements of various quartz tubes with different shapes.

[0025] Compared with the prior art, the beneficial effects of the present invention are: (1) The quartz tube processing device of this patent application can meet the processing requirements of various quartz tubes of different shapes, has good versatility, and is conducive to improving work efficiency; (2) The C-shaped pressure groove on the positioning pressure block presses on the quartz tube to realize the positioning of the quartz tube and improve the stability of the quartz tube; (3) The support surface is set on the rotatable support block, and the tilt angle of the support surface is adjusted as the support block rotates to realize the processing of quartz tubes of different shapes; (4) Quartz During the tube bending process, the arc-shaped bearing surface on the bending bearing block plays a supporting and positioning role for the quartz tube, ensuring that the shape of the quartz tube bending position meets the requirements; (5) The tail fixing block is raised and lowered to prevent the tail of the quartz tube from interfering with the tail fixing block when the quartz tube is bent; (6) After one section of the quartz tube is bent, the arc-shaped clamping surface on the positioning clamp is clamped on the quartz tube to achieve the positioning of the quartz tube, improve the stability of the quartz tube, and prevent the already bent position from being affected when the next section is bent.

[0059] Example 5: A quartz tube processing apparatus (see Figure 7 The device includes a base plate 1, a head fixing block 2, a tail fixing block 3, and positioning blocks 4. The base plate 1 has an L-shaped structure. The head fixing block 2 and positioning blocks 4 are movably mounted on the base plate 1. Several positioning blocks 4 are arranged between the head fixing block 2 and the tail fixing block 3. In this embodiment, two positioning blocks 4 are provided. The base plate 1 is provided with guide grooves 5 corresponding to the head fixing block 2 and positioning blocks 4. Guide blocks 6 are provided at the lower ends of the head fixing block 2 and positioning blocks 4, and the guide blocks 6 are slidably connected to the guide grooves 5. Both the guide grooves 5 and the guide blocks 6 have an inverted T-shaped structure. After the head fixing blocks 2 and positioning blocks 4 slide into place, they are firmly fixed to the base plate 1 by screws. When the head fixing blocks 2 and positioning blocks 4 slide on the base plate 1, the guide blocks 6 slide along the guide grooves 5, ensuring smooth and reliable movement.

[0060] A positioning slot 7 is provided on the head fixing block 2. The positioning slot 7 has a circular structure and its axis is arranged horizontally. A positioning insertion hole 8 is provided on the tail fixing block 3, and its axis is arranged vertically. The head fixing block 2 and the tail fixing block 3 are respectively installed at both ends of the base plate 1.

[0061] The positioning block 4 is provided with a support surface 9 and a mating surface 10. The support surface 9 is inclined, and the support surface 9 and the mating surface 10 respectively support and position the quartz tube 16. The upper end of the positioning block 4 is provided with an upwardly protruding positioning plate 11, and the side of the positioning plate 11 serves as the mating surface 10.

[0062] A positioning block 12 is connected to the upper part of the head fixing block 2. The positioning block 12 has a C-shaped groove 13 that presses against the quartz tube 16. After the head of the quartz tube 16 is inserted into the positioning slot 7, the positioning block 12 is connected to the head fixing block 2. The C-shaped groove 13 on the positioning block 12 presses against the quartz tube 16, achieving positioning of the quartz tube 16 and improving its stability. A slot 14 is provided on the positioning block 12, with its opening facing downwards. The slot 14 is inserted into the upper end of the head fixing block 2. Two locking points 15 are provided on one inner wall of the slot 14, which lock onto the side wall of the positioning slot 7. The positioning block 12 is connected to the upper end of the head fixing block 2 via the slot 14, facilitating assembly and disassembly. The two locking points 15 on the positioning block 12 lock onto the side wall of the positioning slot 7, improving the reliability of the connection between the positioning block 12 and the head fixing block 2. To improve the reliability of the connection between the positioning block 12 and the head fixing block 2, the positioning block 12 is fastened to the head fixing block 2 by screws.

[0063] A rotatable positioning clamping block 32 is mounted on the positioning block 4. The positioning clamping block 32 has an arc-shaped clamping surface 33. Rotation of the positioning clamping block 32 clamps the arc-shaped clamping surface 33 around the upper circumference of the quartz tube 16. A buffer pad is provided on the arc-shaped clamping surface 33. A gear 34 is mounted on the positioning clamping block 32, rotatably connecting it to the positioning block 4. A movable rack 35 is mounted on the positioning block 4, meshing with the gear 34 for transmission. A push-pull screw 36 is threaded onto the positioning block 4, its end rotatably connected to the rack 35. Rotation of the push-pull screw 36 drives the rack 35 to move, which in turn drives the gear 34 to rotate, thus rotating the positioning clamping block 32 and clamping / releasing the quartz tube 16.

[0064] After one section of the quartz tube 16 is bent, the positioning clamp 32 is rotated so that the arc-shaped clamping surface 33 on the positioning clamp 32 clamps onto the quartz tube 16, thereby positioning the quartz tube 16 and improving its stability. This prevents the already bent section from being affected when the next section is bent.

[0065] A method for processing quartz tubes, using a quartz tube processing device, includes the following steps: S1, adjusting the positions of the head fixing block 2 and the positioning block 4 according to the specifications of the quartz tube 16; S2, inserting the head of the quartz tube 16 into the positioning slot 7 and marking the heat treatment position; initially, the quartz tube 16 is a straight tube, and a disc is provided at the head of the quartz tube 16, which is fitted and positioned in the positioning slot 7; S3, heat-treating and bending the quartz tube 16, and then supporting it with a support. On the support surface 9, the tail end of the quartz tube 16 is inserted into the positioning socket 8. The positioning clamping block 32 is rotated, causing the arc-shaped clamping surface 33 on the positioning clamping block 32 to clamp the quartz tube 16, thus positioning the quartz tube 16. The front section of the quartz tube 16 is supported on the support surface 9 of one positioning block 4 and abuts against the mating surface 10, while the rear section of the quartz tube 16 is supported on the support surface 9 of another positioning block 4 and abuts against the mating surface 10. After the tail end of the quartz tube 16 is fully heated, it is inserted into the positioning socket 8. After cooling, the quartz tube 16 is removed to prepare for the processing of the next quartz tube 16.

[0066] Example 6: A quartz tube processing device, similar in structure to Example 1, with the main difference being that a support block 17 is rotatably mounted on the positioning block 4 in this example. The upper surface of the support block 17 is a support surface 9. A push-pull block 18 is mounted on the positioning block 4, and the push-pull block 18 pushes the support block 17 to rotate, thereby adjusting the tilt angle of the support surface 9. A sliding groove 19 is provided on the positioning block 4, and the push-pull block 18 is slidably mounted in the sliding groove 19. An inclined push-pull groove 20 is provided on the push-pull block 18, and a guide post 21 is provided on the support block 17. The guide post 21 is movably inserted into the push-pull groove 20. A drive screw 22 is threadedly connected to the positioning block 4, and the end of the drive screw 22 is rotatably connected to the push-pull block 18. An installation groove 23 is provided on the push-pull block 18, and a convex ring 24 is provided at the end of the drive screw 22. The convex ring 24 is rotatably mounted in the installation groove 23, and a limiting ring 25 is connected to the open end of the installation groove 23, limiting the convex ring 24. The drive screw 22 rotates, which drives the push-pull block 18 to move, thereby driving the support block 17 to rotate, thus adjusting the tilt angle of the support surface 9.

[0067] The support surface 9 is mounted on a rotatable support block 17. As the support block 17 rotates, the tilt angle of the support surface 9 can be adjusted to process quartz tubes 16 of different shapes. The support block 17 is rotated by a push-pull block 18, making the operation convenient and reliable.

[0068] Bending support blocks 26 are provided between the positioning blocks 4 and between the positioning blocks 4 and the tail fixing block 3. The bending support blocks 26 are mounted on the base plate 1, are slidable, and can be moved in position, and are fixed in place by screws. An arc-shaped support surface 27 is provided on the bending support block 26, and the quartz tube 16 abuts against the arc-shaped support surface 27. During the bending process of the quartz tube 16, the arc-shaped support surface 27 on the bending support block 26 provides support and positioning for the quartz tube 16, ensuring that the shape of the bent position of the quartz tube 16 meets the requirements.

[0069] The tail fixing block 3 is lifted and mounted on the base plate 1. A positioning spring 28 is installed between the tail fixing block 3 and the base plate 1, and the positioning spring 28 abuts against the lower end of the tail fixing block 3. Several guide rods 29 are provided on the base plate 1, and guide holes 30 are provided on the tail fixing block 3. The guide rods 29 are movably inserted into the guide holes 30, and positioning nuts 31 are connected to the guide rods 29. Under the action of the positioning spring 28, the tail fixing block 3 presses against the positioning nuts 31.

[0070] Before the tail of the quartz tube 16 is inserted into the positioning hole 8, the tail fixing block 3 is pressed downwards so that it is lower than the tail of the quartz tube 16. After the tail of the quartz tube 16 is aligned with the positioning hole 8, the tail fixing block 3 is released. Under the action of the positioning spring 28, the tail fixing block 3 is pushed upwards, thereby allowing the positioning hole 8 to be inserted into the tail of the quartz tube 16 for positioning. The lifting and lowering setting of the tail fixing block 3 prevents interference between the tail of the quartz tube 16 and the tail fixing block 3 when the quartz tube 16 is bent.

[0071] A rotatable positioning clamping block 32 is mounted on the positioning block 4. The positioning clamping block 32 has an arc-shaped clamping surface 33. Rotation of the positioning clamping block 32 clamps the arc-shaped clamping surface 33 around the upper circumference of the quartz tube 16. A buffer pad is provided on the arc-shaped clamping surface 33. A gear 34 is mounted on the positioning clamping block 32, rotatably connecting it to the positioning block 4. A movable rack 35 is mounted on the positioning block 4, meshing with the gear 34 for transmission. A push-pull screw 36 is threaded onto the positioning block 4, its end rotatably connected to the rack 35. Rotation of the push-pull screw 36 drives the rack 35 to move, which in turn drives the gear 34 to rotate, thus rotating the positioning clamping block 32 and clamping / releasing the quartz tube 16.

[0072] After one section of the quartz tube 16 is bent, the positioning clamp 32 is rotated so that the arc-shaped clamping surface 33 on the positioning clamp 32 clamps onto the quartz tube 16, thereby positioning the quartz tube 16 and improving its stability. This prevents the already bent section from being affected when bending the next section. Other structures are the same as in Embodiment 1.

[0073] A method for processing quartz tubes, using a quartz tube processing device, includes the following steps: S1, adjusting the positions of the head fixing block 2 and the positioning block 4 according to the specifications of the quartz tube 16, and adjusting the tilt angle of the support surface 9; S2, inserting the head of the quartz tube 16 into the positioning slot 7, and marking the heat treatment position; initially, the quartz tube 16 is a straight tube, with a disc at the head, the disc being fitted and positioned into the positioning slot 7; S3, heat-treating and bending the quartz tube 16, the bending position abutting against the arc-shaped bearing surface 27, and after bending, supporting it on the support surface 9, the tail of the quartz tube 16 being inserted into the positioning hole 8; quartz Before inserting the tail of tube 16 into the positioning socket 8, press the tail fixing block 3 downwards so that it is lower than the tail of quartz tube 16. After the tail of quartz tube 16 is aligned with the positioning socket 8, release the tail fixing block 3. Under the action of the positioning spring 28, the tail fixing block 3 is pushed upwards, thereby positioning the positioning socket 8 and the tail of quartz tube 16 together. The front section of quartz tube 16 is supported on the support surface 9 of a positioning block 4 and abuts against the abutment surface 10. The rear section of quartz tube 16 is supported on the support surface 9 of another positioning block 4 and abuts against the abutment surface 10. After the tail of quartz tube 16 is fully heated, it is inserted into the positioning socket 8. Rotate the positioning clamp 32 so that the arc-shaped clamping surface 33 on the positioning clamp 32 clamps onto the quartz tube 16, thereby positioning the quartz tube 16. After cooling, remove the quartz tube 16 to prepare for the processing of the next quartz tube 16.
