Description

Technical Field

[0001] This invention belongs to the field of quartz tube processing technology, specifically relating to a positioning device for laser drilling of quartz tubes. Background Technology

[0002] Laser drilling of quartz tubes is a technology that uses a high-energy-density laser beam to perform non-contact micro-hole processing on quartz tubes. It can solve the problems of easy breakage, low precision and poor efficiency of traditional mechanical drilling. The core is to achieve high-precision processing of micron- to millimeter-level hole diameters by instantly melting and vaporizing quartz material with laser energy.

[0003] Quartz plates are mainly composed of silicon dioxide, and high-purity quartz sand or quartz ore is usually selected as raw material. The silicon dioxide content is generally required to be above 99% to ensure that the fused quartz plates produced have excellent performance. The positioning device is the core component for achieving high-precision processing. Its design needs to take into account the physical properties of quartz materials (such as brittleness and low coefficient of thermal expansion) and the dynamic requirements of laser processing. The positioning device for laser drilling of quartz tubes is a key technology in the field of precision manufacturing, and its performance directly affects product quality and production efficiency.

[0004] Existing quartz laser drilling equipment typically uses a snap-fit ​​structure to fix the quartz tube in its fixing module. This module lacks specific limiting structures for quartz tubes of different lengths, making it difficult to provide convenient and stable positioning for tubes of varying lengths. This leads to frequent misalignment during laser drilling, resulting in limited applicability. Different snap-fit ​​fixtures are often required when processing quartz tubes of varying lengths, and it cannot securely fix extremely long tubes. Furthermore, existing quartz laser drilling equipment relies heavily on sensor monitoring and distance measurement for drilling positioning, making it overly dependent on information technology. The drilling position is not intuitive enough, resulting in limited ease of operation and requiring repeated verification of the positioning hole distance. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a positioning device for laser drilling of quartz tubes.

[0006] The technical solution adopted to solve the above technical problems is: a positioning device for laser drilling of quartz tubes, including an operating table mechanism, a drive mechanism, a movable plate mechanism, a fixed plate mechanism and a moving mechanism. The bottom of the operating table mechanism is fixed with the drive mechanism, which includes a first motor. The output end of the first motor is fixed with a shaft. Two drive gears are coaxially fixed to the outside of the shaft. The movable plate mechanism is slidably arranged on the operating table mechanism. The movable plate mechanism includes a movable frame. Two racks are fixed to one end of the movable frame, and a movable plate body is fixed to the top of the movable frame. The movable plate body is provided with multiple fixing mechanisms, and the operating table mechanism is fixedly installed with a fixing plate mechanism. The fixing plate mechanism includes a fixing strip, and a fixing plate body is fixed to the top of the fixing strip. The fixing plate body has multiple round holes. A lifting plate mechanism is slidably arranged on the fixing plate mechanism. The lifting plate mechanism includes a lifting plate body slidably arranged inside the fixing plate body. Both ends of the lifting plate body are fixed with connecting ears, and hand-tightening screws are passed through the connecting ears. The top of the operating platform mechanism is fixed with a top frame mechanism, a moving mechanism is installed on the inner side of the top frame mechanism, a monitoring mechanism is fixed on the moving mechanism, a laser drilling mechanism is fixed on the moving mechanism, and a horizontal laser mechanism is fixed on the top frame mechanism.

[0007] Furthermore, the operating platform mechanism includes a support leg, the top of which is fixed to the operating platform body, a reinforcing brace is fixed to the inner side of the support leg, an installation groove is fixed on the operating platform body, a sliding groove is provided on the inner side of the operating platform body, and multiple grooves are provided on the operating platform body.

[0008] Through the above technical solution, the operating platform body, support legs, and reinforcing brace can all be made of stainless steel, which has high strength and corrosion resistance. The support legs can further improve the structural strength of the device. The monitoring mechanism can be a laser rangefinder or a radar rangefinder, which can monitor the distance to the quartz tube and the location of the moving mechanism.

[0009] Furthermore, a first connecting frame is rotatably connected to the end of the shaft, the top of the first connecting frame is fixed to the operating table body, and a second connecting frame is fixed to the first motor, the top of the second connecting frame is fixed to the operating table body.

[0010] With the above technical solution, when the first motor starts, the shaft will be driven to rotate, thereby causing the drive gear to rotate. The first connecting frame and the second connecting frame can effectively ensure the stability of the shaft.

[0011] Furthermore, two sliders are fixed on the movable frame, the sliders are slidably connected to the slide groove, the rack meshes with the drive gear, and multiple tube slots are provided on the movable plate body.

[0012] Through the above technical solution, the cooperation between the slider and the slide groove allows the movable frame to slide along the slide groove. When the drive gear rotates, the rack meshing with it will be driven to translate, thereby causing the movable frame to translate, which in turn changes the distance between the movable plate mechanism and the fixed plate mechanism, making the device applicable to a variety of quartz tubes of different lengths.

[0013] Furthermore, the fixing mechanism includes a connecting part fixed to the inner side of the tube slot, a mounting block fixed on the connecting part, three telescopic rods arranged in a circular array on the outer side of the mounting block, and an arc-shaped pressure block fixed to the end of the telescopic rod.

[0014] With the above technical solution, the telescopic rod can be electrically driven, hydraulically driven, or pneumatically driven. When one end of the quartz tube is inserted into the tube slot, the operator can open the telescopic rod. When the telescopic rod extends, the arc-shaped pressure block will squeeze the inner wall of the quartz tube from the inside, thereby fixing one end of the quartz tube.

[0015] Furthermore, threaded grooves are provided at both ends of the fixed plate, and multiple protrusions are integrally fixed on the inner side of the fixed plate. Multiple grooves are provided on the lifting plate, and the grooves are slidably connected to the protrusions. The hand-tightening screw is threadedly connected to the threaded groove.

[0016] Through the above technical solution, the protrusions and grooves can limit the movement of the lifting plate, making the sliding stability of the lifting plate higher. When the quartz tube is short, the operator fixes one end of the quartz tube to the fixing mechanism, then loosens the hand screw and inserts the lifting plate to the bottom. At this time, the other end of the quartz tube can be stuck in the groove structure formed by the lifting plate and the round hole, thus fixing the quartz tube. The bottom of the lifting plate, corresponding to the round hole, has an arc-shaped structure. When the quartz tube is long, the operator can pull up the lifting plate, pass the quartz tube through the round hole, press the lifting plate down, and tighten the hand screw to further press the quartz tube, thereby fixing the longer quartz tube. This device can not only fix both ends of quartz tubes of different lengths, but also fix extra-long quartz tubes, further improving the applicability of the device.

[0017] Furthermore, the moving mechanism includes a shaft support fixed to the top frame mechanism. Two shaft supports are provided. A semi-threaded screw is rotatably connected to the inner side of the shaft support. One end of the semi-threaded screw is connected to a second motor. The second motor is fixed to the top frame mechanism. A synchronous pulley is coaxially fixed to the outer side of the semi-threaded screw.

[0018] Through the above technical solution, the output shaft of the second motor is fixed to the semi-threaded screw, and the other end of the semi-threaded screw is rotatably connected to the top frame mechanism. When the second motor starts, the semi-threaded screw and the synchronous pulley will also rotate. The shaft support seat effectively improves the stability of the semi-threaded screw.

[0019] Furthermore, a synchronous belt is engaged with the synchronous pulley, and a synchronous screw is engaged with the other end of the synchronous belt. A sliding seat is threaded onto the synchronous screw, and a first electric guide rail is fixed to the bottom of the sliding seat.

[0020] Through the above technical solution, the synchronous lead screw is equipped with the same synchronous pulley and shaft support structure as the semi-threaded lead screw, and the specifications of the synchronous lead screw are the same as those of the semi-threaded lead screw. When the second motor starts, the synchronous pulley and synchronous belt transmit power to the synchronous lead screw, so that the synchronous lead screw and the semi-threaded lead screw rotate synchronously, thereby driving the sliding seat to translate along the semi-threaded lead screw and the synchronous lead screw. The synchronous lead screw effectively ensures the stability of the sliding seat and the consistency of the displacement at both ends. The moving direction of the connecting seat on the first electric guide rail is perpendicular to the moving direction of the sliding seat.

[0021] Furthermore, the laser drilling mechanism includes a connecting seat fixed on a slide of the first electric guide rail, a laser emitter fixed at the bottom of the connecting seat, an inclined mounting seat fixed at one end of the connecting seat, and a longitudinal laser beam fixed at the bottom of the inclined mounting seat.

[0022] Through the above technical solution, driven by the moving mechanism, the laser drilling mechanism can move on the X and Y axes, thereby moving the laser emitter to a designated position to drill a hole in the quartz tube, and the longitudinal laser pointer emitted by the longitudinal laser beam is directed toward the position where the laser emitter contacts the quartz tube.

[0023] Furthermore, the transverse laser mechanism includes a second electric guide rail fixed to the top frame mechanism, a guide rail slide table slidably connected to the second electric guide rail, a mounting frame fixed on the guide rail slide table, a servo motor fixed at the bottom of the mounting frame, and a transverse laser beam fixed at the output end of the servo motor.

[0024] Through the above technical solution, the second electric guide rail can drive the guide rail slide and the connecting seat to move synchronously, so that the position of the transverse laser beam on the X-axis is synchronized with the laser emitter. The servo motor can adjust the angle of the transverse laser beam according to the position of the laser emitter on the Y-axis, so that the transverse laser indicator emitted by the transverse laser beam points to the contact point between the laser emitter and the quartz tube. The longitudinal laser indicator and the transverse laser indicator can jointly form a crosshair. The intersection of the crosshairs is the pointing position of the laser emitter, which can indicate the drilling position to the operator and achieve precise drilling positioning.

[0025] The beneficial effects of this invention are as follows: 1. The present invention, through the arrangement of the movable plate mechanism, the fixing mechanism and the fixed plate mechanism, enables the device to clamp and position quartz tubes of different lengths, avoids displacement of the quartz tubes during the drilling process, and can also clamp and position ultra-long quartz tubes, further improving the applicability of the device; 2. By incorporating a moving mechanism, a laser drilling mechanism, and a transverse laser mechanism, this invention enables the device to form a conspicuous crosshair at the laser's pointing position, thereby indicating the drilling location to the operator and effectively improving the accuracy of drilling positioning.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figures 1-9 As shown, a positioning device for laser drilling of quartz tubes includes an operating platform mechanism 1, a driving mechanism 2, a movable plate mechanism 3, a fixed plate mechanism 5, and a moving mechanism 8. A top frame mechanism 7 is fixed to the top of the operating platform mechanism 1, and a moving mechanism 8 is installed on the inner side of the top frame mechanism 7. A monitoring mechanism 9 is fixed on the moving mechanism 8, and a laser drilling mechanism 10 is fixed on the moving mechanism 8. A transverse laser mechanism 11 is fixed on the top frame mechanism 7. The operating platform mechanism 1 includes a support leg 101, an operating platform body 102 is fixed to the top of the support leg 101, a reinforcing brace 103 is fixed to the inner side of the support leg 101, an installation groove 104 is fixed on the operating platform body 102, a sliding groove 105 is opened on the inner side of the operating platform body 102, and multiple grooves 106 are opened on the operating platform body 102.

[0030] like Figure 1 and Figure 4As shown, a drive mechanism 2 is fixed to the bottom of the operating platform mechanism 1. The drive mechanism 2 includes a first motor 203. A shaft 204 is fixed to the output end of the first motor 203. Two drive gears 205 are coaxially fixed to the outside of the shaft 204. A first connecting frame 201 is rotatably connected to the end of the shaft 204. The top of the first connecting frame 201 is fixed to the operating platform body 102. A second connecting frame 202 is fixed to the first motor 203. The top of the second connecting frame 202 is fixed to the operating platform body 102. When the first motor 203 is started, the shaft 204 will be driven to rotate, thereby causing the drive gears 205 to rotate. The first connecting frame 201 and the second connecting frame 202 can effectively ensure the stability of the shaft 204.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, a movable plate mechanism 3 is slidably mounted on the operating table mechanism 1. The movable plate mechanism 3 includes a movable frame 301. Two racks 303 are fixed at one end of the movable frame 301, and a movable plate body 304 is fixed at the top of the movable frame 301. Two sliders 302 are fixed on the movable frame 301. The sliders 302 are slidably connected to the slide groove 105. The racks 303 mesh with the drive gear 205. The movable plate body 304 has multiple tube-holding slots 305. The cooperation between the sliders 302 and the slide groove 105 allows the movable frame 301 to slide along the slide groove 105. When the drive gear 205 rotates, the racks 303 meshing with it will be driven to translate, thereby causing the movable frame 301 to translate, thus changing the distance between the movable plate mechanism 3 and the fixed plate mechanism 5, so that the device can be applied to various quartz tubes of different lengths.

[0032] like Figure 4 and Figure 5 As shown, the movable plate body 304 is provided with multiple fixing mechanisms 4. The fixing mechanism 4 includes a connecting part 401 fixed to the inner side of the tube slot 305. A mounting block 402 is fixed on the connecting part 401. Three telescopic rods 403 are arranged in a circular array on the outer side of the mounting block 402. An arc-shaped pressure block 404 is fixed to the end of the telescopic rod 403. The telescopic rod 403 can be electrically driven, hydraulically driven, or pneumatically driven. When one end of the quartz tube is inserted into the tube slot 305, the operator can open the telescopic rod 403. When the telescopic rod 403 extends, the arc-shaped pressure block 404 will squeeze the inner wall of the quartz tube from the inside, thereby fixing one end of the quartz tube.

[0033] like Figure 2 and Figure 6As shown, a fixed plate mechanism 5 is fixedly installed on the operating table mechanism 1. The fixed plate mechanism 5 includes a fixed insert 501, and a fixed plate body 502 is fixed to the top of the fixed insert 501. The fixed plate body 502 has multiple round holes 503. A lifting plate mechanism 6 is slidably arranged on the fixed plate mechanism 5. The lifting plate mechanism 6 includes a lifting plate body 601 slidably arranged inside the fixed plate body 502. Both ends of the lifting plate body 601 are fixed with connecting ears 603, and hand-tightening screws 604 pass through the connecting ears 603. Both ends of the fixed plate body 502 are provided with threaded grooves 504. Multiple protrusions 505 are integrally fixed to the inner side of the fixed plate body 502. Multiple grooves 602 are provided on the lifting plate body 601. The grooves 602 are slidably connected to the protrusions 505, and the hand-tightening screws 604 are threadedly connected to the threaded grooves 504. The protrusions 505 and the grooves 602 can limit the lifting plate body 601, so that the lifting plate body 601 can be raised. The sliding stability of the lifting plate 601 is higher. When the quartz tube is short, the operator fixes one end of the quartz tube to the fixing mechanism 4, then loosens the hand screw 604 and inserts the lifting plate 601 to the bottom. At this time, the other end of the quartz tube can be stuck in the groove structure formed by the lifting plate 601 and the round hole 503, thus fixing the quartz tube. The bottom of the lifting plate 601 is arc-shaped, corresponding to the position of the round hole 503. When the length of the quartz tube is long, the operator can pull up the lifting plate 601, pass the quartz tube through the round hole 503, press the lifting plate 601 down, and tighten the hand screw 604 to further press the quartz tube, thereby fixing the longer quartz tube. This device can not only fix the two ends of quartz tubes of different lengths, but also fix extra-long quartz tubes, further improving the applicability of the device.

[0034] like Figure 1 and Figure 7As shown, a top frame mechanism 7 is fixed to the top of the operating platform mechanism 1. A moving mechanism 8 is installed inside the top frame mechanism 7. The moving mechanism 8 includes a shaft support seat 801 fixed to the top frame mechanism 7. Two shaft support seats 801 are provided. A semi-threaded screw 802 is rotatably connected to the inner side of the shaft support seat 801. One end of the semi-threaded screw 802 is connected to a second motor 803. The second motor 803 is fixed to the top frame mechanism 7. A synchronous pulley 804 is coaxially fixed to the outside of the semi-threaded screw 802. A synchronous belt 805 is meshed on the synchronous pulley 804. A synchronous screw 806 is meshed on the other end of the synchronous belt 805. A sliding seat 807 is threadedly connected to the synchronous screw 806. A first electric guide rail 808 is fixed to the bottom of the sliding seat 807. The output shaft of the second motor 803 is fixed to the semi-threaded screw 802. The other end of the semi-threaded screw 802 is rotatably connected to the top frame mechanism 7. Next, when the second motor 803 starts, the semi-threaded screw 802 and the synchronous pulley 804 will also rotate. The shaft support seat 801 effectively improves the stability of the semi-threaded screw 802. The synchronous screw 806 is equipped with the same synchronous pulley 804 and shaft support seat 801 structure as the semi-threaded screw 802, and the specifications of the synchronous screw 806 are the same as those of the semi-threaded screw 802. When the second motor 803 starts, the synchronous pulley 804 and the synchronous belt 805 transmit power to the synchronous screw 806, so that the synchronous screw 806 rotates synchronously with the semi-threaded screw 802, thereby driving the sliding seat 807 to translate along the semi-threaded screw 802 and the synchronous screw 806. The synchronous screw 806 effectively ensures the stability of the sliding seat 807 and the consistency of the displacement at both ends. The moving direction of the connecting seat 1001 on the first electric guide rail 808 is perpendicular to the moving direction of the sliding seat 807.

[0035] like Figure 1 , Figure 7 and Figure 8 As shown, a monitoring mechanism 9 is fixed on the moving mechanism 8, and a laser drilling mechanism 10 is fixed on the moving mechanism 8. The laser drilling mechanism 10 includes a connecting seat 1001 fixed on a slide of the first electric guide rail 808. A laser emitter 1002 is fixed at the bottom of the connecting seat 1001, and an inclined mounting seat 1003 is fixed at one end of the connecting seat 1001. A longitudinal laser beam 1004 is fixed at the bottom of the inclined mounting seat 1003. Driven by the moving mechanism 8, the laser drilling mechanism 10 can move on the X-axis and Y-axis, thereby moving the laser emitter 1002 to a designated position to drill a hole in the quartz tube. The longitudinal laser pointer emitted by the longitudinal laser beam 1004 is directed toward the position where the laser emitter 1002 contacts the quartz tube.

[0036] like Figure 2 and Figure 9As shown, a transverse laser mechanism 11 is fixed on the top frame mechanism 7. The transverse laser mechanism 11 includes a second electric guide rail 1101 fixed on the top frame mechanism 7. A guide rail slide 1102 is slidably connected to the second electric guide rail 1101. A mounting bracket 1103 is fixed on the guide rail slide 1102. A servo motor 1104 is fixed to the bottom of the mounting bracket 1103. A transverse laser beam 1105 is fixed to the output end of the servo motor 1104. The second electric guide rail 1101 can drive the guide rail slide 1102 and the connecting seat 1001 to move synchronously, thereby making the transverse laser beam 1105 move synchronously. The position of 105 on the X-axis is synchronized with that of the laser emitter 1002. The servo motor 1104 can adjust the angle of the transverse laser beam 1105 according to the position of the laser emitter 1002 on the Y-axis, so that the transverse laser pointer emitted by the transverse laser beam 1105 points to the contact point between the laser emitter 1002 and the quartz tube. The longitudinal laser pointer and the transverse laser pointer can together form a crosshair. The intersection of the crosshairs is the pointing position of the laser emitter 1002, which can indicate the drilling position to the operator and achieve precise drilling positioning.

[0037] The working principle of this embodiment is as follows: According to the length of the quartz tube to be drilled, the operator fixes multiple quartz tubes through the drive mechanism 2, the movable plate mechanism 3, the fixed plate mechanism 5 and the lifting plate mechanism 6. Then, the position of the laser drilling mechanism 10 is adjusted by the moving mechanism 8, so that laser drilling is performed at the specified position on the quartz tube. During drilling, the longitudinal laser beam 1004 and the transverse laser beam 1105 can project a crosshair at the pointing point of the laser drilling mechanism 10, so that the operator can accurately locate the drilling position.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
