Description

Technical Field

[0001] This invention relates to the field of quartz tube bending measurement technology, specifically a multi-parameter testing device for quartz tube bending. Background Technology

[0002] The lamp tube is the core component of a tungsten halogen lamp. It serves to insulate against external ventilation during operation and must not crack or deform due to operating temperatures. Tungsten halogen lamp tubes are made by sintering and bending quartz tubes. Since the size of the tube affects its performance, its dimensional parameters need to be measured after sintering and bending to ensure it meets usage standards. However, existing measuring fixtures can only measure length or diameter, making it difficult to determine if the entire quartz tube is in a plane, and also hindering the measurement of the degree of bending and uniformity, thus reducing the accuracy and comprehensiveness of the inspection.

[0003] The existing pipe bending testing equipment has the following drawbacks:

[0004] The application document CN118688043A mainly considers how to improve the detection stability during the automatic detection of quartz tubes, but does not consider how to detect whether quartz bent tubes are coplanar.

[0005] The patent document CN214039794U can only detect the length of the quartz tube, but does not consider how to detect the degree of bending, longitudinal dimension, and diameter of the quartz tube.

[0006] The patent document CN202903074U can only achieve the length of a straight quartz tube, but it is difficult to detect the uniformity of the quartz tube itself and to achieve the purpose of multi-parameter detection. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a coplanar measurement component to fix the quartz bend to be tested via a fixed block and a moving block. Then, a servo motor is started, which drives the parameter measurement module to move via a lead screw. The starting position of the infrared light generator is determined by a photosensitive sensor and a laser emitter. The infrared light generator is then started and the moving block continues to slide. The infrared light detection unit detects whether it receives infrared light, thereby measuring whether the bottom of the quartz bend is in contact with the top of the measuring platform. This achieves the measurement of the overall coplanarity of the quartz bend and improves the detection accuracy of the quartz bend.

Furthermore, together with distance sensor three, it detects whether the bent tube has excessive longitudinal length, excessive large arc bending, or insufficient small arc bending, thus improving the detection effect on quartz bent tubes.

[0022] 3. This invention, by installing a uniform measurement component, uses a measuring rod, pressure sensor three, and distance sensor four to measure and detect the diameter of the large arc section of the bend. Then, a servo motor drives the rotating seat to rotate, and a fixed rod, telescopic rod, and ring sleeve drive the measuring rod to rotate to the right and left to detect the uniformity of the diameter of the large arc section of the bend, further improving the comprehensiveness of the detection equipment.

[0023] 4. This invention, by installing a parameter measurement module, utilizes a movable frame, a distance sensor, and a fixed block to detect the overall lateral length of a quartz bend.

[0036] Please see Figure 1 and Figure 4 An embodiment of the present invention provides a multi-parameter detection device for quartz bent tubes, comprising a measuring platform 1, a coplanar measuring component 2 and a T-shaped bracket 25 disposed on the top of the measuring platform 1, a control panel 49 mounted on the right side of the measuring platform 1, and the control panel 49 being electrically connected to the coplanar measuring component 2, the coplanar measuring component 2 comprising a measuring plate 5 and a fixing block 7 fixedly mounted on the top of the measuring platform 1, a parameter measuring module 8 slidably connected to the top of the measuring platform 1, the parameter measuring module 8 comprising a movable frame 9 slidably connected to the back of an infrared light detection unit 6, a push plate 21 embedded on the right side of the movable frame 9, the push plate 21 being slidably connected to the inner wall of the movable frame 9, a pressure sensor 22 and a spring 23 installed inside the movable frame 9, the spring 23 being installed in two sets, the spring 23 being located at the pressure sensor 22. On the front and rear sides of 22, the right end of spring 23 is connected to the outer wall of push plate 21. The force-bearing surface of pressure sensor 22 is in contact with the left outer wall of push plate 21. The control panel 49 is equipped with the measurement standard value B1 of pressure sensor 22, and B1 is 1N. By setting a smaller standard value, when push plate 21 in moving frame 9 is in contact with the left end of the bent tube, it can position the bent tube without causing the bent tube to move on the top of measuring table 1. The positioning of the bent tube by push plate 21 and moving frame 9 will not cause cracks, deformation, or scratches on the bent tube. Distance sensor 24 is embedded in the right outer wall of moving frame 9 and is located behind push plate 21. Distance sensor 24 is used to detect the distance between moving frame 9 and fixed block 7.

[0037] Furthermore, the quartz bend to be tested is placed on top of the measuring platform 1, with the right end of the bend in contact with the fixing block 7 and the front of the bend in contact with the back of the infrared light detection unit 6. The servo motor 13 drives the lead screw 14 to rotate, thereby causing the parameter measurement module 8 to slide along the top of the measuring platform 1, so that the right side of the parameter measurement module 8 is in contact with the left end of the bend. The bend exerts a force on the push plate 21, and the force value is detected by the pressure sensor 22. When the value detected by the pressure sensor 22 is between 0 and B1, the servo motor 13 is turned off, so that the moving frame 9 stops moving. At this time, the left end face of the bend, the right side face of the moving frame 9 and the right side face of the push plate 21 are on the same plane. Then, the distance between the moving frame 9 and the fixing block 7 is measured by the distance sensor 24, thereby measuring the overall length of the bend and achieving the purpose of detecting the overall length of the quartz bend. When the measured length is different from the actual required overall length, it indicates that the quartz bend is a defective product.

[0038] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8This invention provides an embodiment of a multi-parameter testing device for quartz bent tubes, comprising a measuring platform 1, a coplanar measuring component 2 and a T-shaped bracket 25 disposed on the top of the measuring platform 1, a control panel 49 mounted on the right side of the measuring platform 1, and the control panel 49 being electrically connected to the coplanar measuring component 2. The coplanar measuring component 2 includes a measuring plate 5 fixedly mounted on the top of the measuring platform 1 and a fixing block 7, with the fixing block 7 located on the right side of the measuring plate 5, and the right outer wall of the measuring plate 5 fitting against the left outer wall of the fixing block 7. An infrared light detection unit 6 is mounted on the back of the measuring plate 5. Measurement unit 6 includes an infrared photoresistor and a resistance value detection sensor or an infrared photodiode and a voltage value detection sensor connected to it. A parameter measurement module 8 is slidably connected to the top of the measuring platform 1, and the front of the parameter measurement module 8 is slidably connected to the back of the infrared light detection unit 6. The parameter measurement module 8 includes a movable frame 9 slidably connected to the back of the infrared light detection unit 6. A connecting bracket 11 is mounted on the top of the movable frame 9. A step plate 12 is mounted on the front of the measuring platform 1, and a servo motor 13 is mounted on the top of the step plate 12. The step plate 12 is a servo motor. Servo motor 13 provides the installation position. The output end of servo motor 13 is connected to lead screw 14, which is set horizontally along the measuring table 1. Connecting frame 11 is sleeved on the outer wall of lead screw 14. A protruding strip is installed on the top of step plate 12 and is embedded in the bottom of connecting frame 11. The protruding strip provides limit and guidance for connecting frame 11. Laser emitter 10 is installed on the back of moving frame 9. Servo motor 2 17 is installed inside measuring plate 5. The output end of servo motor 2 17 is connected to lead screw 2 18. Parameter measurement module 2 is sleeved on the outer wall of lead screw 2 18. 15. Parameter measurement module 2 includes a movable block 16 embedded in the top of the measuring stage 1. A photosensitive sensor 20 and an infrared light generator 19 are mounted on the front of the movable block 16. The infrared light generator 19 is located below the photosensitive sensor 20 and is electrically connected to the photosensitive sensor 20. The photosensitive sensor 20 and the laser emitter 10 are located on the same horizontal line. The infrared light generator 19 is used to generate infrared light along the top of the measuring stage 1 to the parameter measurement module 1. The photosensitive sensor 20 is used to receive the laser emitted by the laser emitter 10.

[0039] Furthermore, after the overall length dimension of the quartz bent tube passes inspection, the laser emitter 10 and servo motor 17 are activated via the control console. Servo motor 17 drives lead screw 18 to rotate, causing parameter measurement module 15 to move to the right along the slide groove at the top of the measuring platform 1. When the photosensitive sensor 20 on the front of parameter measurement module 15 detects that it has received laser light emitted by the laser emitter 10 on the back of parameter measurement module 15, the infrared light generator 19 in parameter measurement module 15 is activated, emitting infrared light forward along the top of the measuring platform 1, while the laser emitter 10 in parameter measurement module 15 is deactivated. Close, the moving block 16 continues to slide to the right, and the infrared light detection unit 6 measures whether it receives infrared light, thereby determining whether the bottom of the quartz bend is in contact with the top of the measuring platform 1. For example, when the infrared light detection unit 6 receives infrared light, it indicates that there is a gap between the bottom of the bend and the top of the measuring platform 1. In this case, the bottom of the bend may have a bulge, the rounded corners of the bend may be raised upwards or downwards, and the large arc of the bend may be arched upwards or concave downwards, etc., which means that the entire bend cannot be coplanar, resulting in the quartz bend being unqualified. By setting the coplanar measurement component 2, the overall coplanarity of the quartz bend can be measured, which improves the detection accuracy of the quartz bend.

[0040] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 One embodiment of the present invention provides a multi-parameter testing device for quartz bent tubes. A T-shaped bracket 25 at the top of the measuring platform 1 is located behind the coplanar measuring component 2. A vertical electric actuator 26 is mounted on the top of the T-shaped bracket 25. The output end of the vertical electric actuator 26 is connected to a degree measuring component 4, which is located above the measuring platform 1. The degree measuring component 4 includes a lifting plate 27. A standard detection arc plate 28 is detachably mounted at the bottom of the lifting plate 27. The standard detection arc plate 28 consists of a large arc plate with a known radius and center, small arc plates with known arc angles on both sides of the large arc plate, and a horizontal plate. 28 is located between the moving frame 9 and the fixed block 7. A lifting block 29 is embedded in the bottom of the standard detection arc plate 28. A pressure sensor 20 and a spring 21 are installed on the top of the lifting block 29. The spring 21 is located on both sides of the pressure sensor 20. A distance sensor 22 is embedded in the bottom of the lifting block 29. The distance sensor 22 is used to detect the distance from its bottom to the top of the measuring platform 1. Multiple sets of distance sensors 33 are embedded in the front side of the standard detection arc plate 28. The distance sensors 33 are used to measure the distance from the front side of the standard detection arc plate 28 to the outer wall of the bend.

[0041] Furthermore, after the coplanar measurement component 2 detects the overall coplanarity of the bent tube, the vertical electric push rod 26 extends, pushing the standard detection arc plate 28 downward. When the lifting block 29 at the bottom of the standard detection arc plate 28 is squeezed, causing the detection data of the pressure sensor 2 to be non-zero, the distance sensor 2 32 is activated to detect the distance between the bottom of the lifting block 29 and the top of the measuring platform 1. When the measurement data obtained by the distance sensor 2 32 is non-zero, it indicates that the bottom of the lifting block 29 is attached to the top of the measuring platform 1, indicating that the standard detection arc plate 28 cannot be stuck on the outside of the quartz bent tube. The quartz bent tube may have an excessively large longitudinal length, incomplete bending of the large arc segment, excessive bending of the small arc segment, or a straight section of the bent tube. If the diameter is too large, the tested bend is a defective product. When the measurement data obtained by the distance measuring sensor 2 32 is 0, the distance from the front side wall of the standard detection arc plate 28 to the back of the bend is measured by the distance measuring sensor 3 33. When the measurement value obtained by the distance measuring sensor 3 33 is not 0, it means that the front side wall of the standard detection arc plate 28 is not in contact with the back of the bend. The bend may have problems such as the longitudinal length dimension being too small, the large arc segment being over-bent, and the small arc segment not being bent enough. The tested bend is a defective product. By setting the degree measurement component 4, the degree of bending, pipe diameter and longitudinal length dimension of the arc segment of the bend can be detected, which helps to improve the accuracy and comprehensiveness of the detection of quartz bends.

[0042] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6One embodiment of the present invention provides a multi-parameter detection device for quartz bent tubes. The sliding seat 35 in the uniform measurement component 3 is U-shaped, with its horizontal portion located below the lifting plate 27. The vertical portion of the sliding seat 35 penetrates the top of the lifting plate 27. A horizontal electric push rod 34 is installed on the top of the lifting plate 27, located on both sides of the vertical electric push rod 26. The output end of the horizontal electric push rod 34 is connected to the back of the sliding seat 35. A measuring rod 36 is embedded in the bottom of the sliding seat 35. A pressure sensor 37 and a distance sensor 38 are installed on the back of the measuring rod 36. The distance sensor 38 is located below the pressure sensor... Above the measuring device 37, the distance sensor 48 is used to detect the distance from the back of the measuring rod 36 to the front side of the surface detection arc plate. The control panel 49 is equipped with the standard measurement value B3 of the pressure sensor 37. B3 is 1N. When the force between the measuring rod 36 and the bend is less than the standard measurement value B3, the measuring bend 36 will not be damaged by cracks, surface scratches, or other phenomena. The uniform measurement assembly 3 also includes a detachable mounting base 39 on the top of the lifting plate 27. The mounting base 39 is embedded in the top of the lifting plate 27, and there is a sliding connection between the mounting base 39 and the embedded connection of the lifting plate 27. The mounting base 39 is located on the sliding seat 35. On the front side, a servo motor 40 is mounted on the top of the mounting base 39. The output shaft of the servo motor 40 is located above the center of the large arc of the standard quartz bend. The output of the servo motor 40 is connected to a rotating base 41. A fixed rod 42 is mounted on the back of the rotating base 41. A telescopic rod 43 is mounted through the back of the fixed rod 42. An electromagnet 44 is mounted on the front end of the telescopic rod 43. The inner wall of the fixed rod 42 is provided with an iron inner layer, and the outer wall of the electromagnet 44 is slidably connected to the iron inner layer. A ring 47 is mounted on the rear end of the telescopic rod 43. The ring 47 is fitted onto the outer wall of the measuring rod 36 and is fixedly connected to the outer wall of the measuring rod 36. The ring 47 is located above the distance sensor 38. A force sensor 48 is installed on the outer wall of the telescopic rod 43. The force sensor 48 is used to detect the stress on the telescopic rod 43. A miniature electric push rod 45 is installed on the top of the sliding seat 35 and is located below the lifting plate 27. The output end of the miniature electric push rod 45 is connected to the insertion rod 46. The insertion rod 46 passes through the front of the sliding seat 35 and the outer wall of the measuring rod 36. The insertion rod 46 is used to fix the measuring rod 36. When the measuring rod 36 is fixed, it is located on the middle symmetrical line of the standard detection arc plate 28. The electromagnet 44, the pressure sensor 37, and the miniature electric push rod 45 are electrically connected.

[0043] Furthermore, after the degree measurement component 4 completes the detection, the horizontal electric push rod 34 shortens, pulling the sliding seat 35 to move the measuring rod 36 backward. At this time, the sliding seat 35 and the measuring rod 36 are fixed together by the insertion rod 46, and the electromagnet 44 is not energized. The measuring rod 36 moves forward until the pressure sensor 37 is in contact with the front wall of the bend. When the measured value obtained by the pressure sensor 37 is between 0 and B3, the sliding seat 35 stops moving. At the same time, the back of the measuring rod 36 is in contact with the front wall of the bend. The bend detects the distance from the outer wall of the measuring rod 36 to the standard detection arc plate 28 through the distance sensor 48, thereby obtaining the diameter of the large arc part of the quartz bend. At the same time, the measurement data of the force sensor 48 is obtained. Then, the miniature electric push rod 45 extends, driving the insertion rod 46 forward, causing the insertion rod 46 to separate from the measuring rod 36, and energizing the electromagnet 44, thereby relative to the fixed Rod 42 fixes the position of telescopic rod 43. Servo motor 3 40 drives rotating seat 41 to rotate. Rotating seat 41 drives measuring rod 36 to rotate to the right through fixed rod 42, telescopic rod 43 and ring 47. When the data of force sensor 48 increases or the measurement data of pressure sensor 3 decreases during rotation, the large arc part of the surface bend may have outward convexity or inward concavity, resulting in uneven actual diameter of the bend. Then servo motor 3 40 reverses and drives measuring rod 36 back to its original position. Then it drives measuring rod 36 to rotate to the left again, so that measuring rod 36 can realize the detection within the standard angle range corresponding to the standard arc segment of the bend, thereby improving the accuracy of the bend detection results and avoiding detection dead angles. After the measuring rod 36 is used, it is rotated to its original position and the insertion rod 46 is pulled backward by micro electric push rod 45 to fix measuring rod 36.

[0044] Working Principle: This multi-parameter testing device for quartz bends uses a coplanar measurement component 2 and a movable parameter measurement module 1 8 to measure the overall lateral length of the bend. Parameter measurement module 2 15 emits infrared light forward, and an infrared light detection component checks whether the bend is illuminated by infrared light from its front, thus determining whether the entire bend is on the same plane. A standard detection arc plate 28 is used to measure the degree of bending, diameter, and longitudinal length of the bend's arc segment, improving the accuracy and comprehensiveness of the quartz bend testing. A measuring rod 36 measures the diameter and uniformity of the large arc segment of the bend, detecting various bend defects and achieving comprehensive testing of the quartz bend, thus improving the accuracy and comprehensiveness of the quartz bend testing.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
