[0002] The lamp tube is the core component of the tungsten halogen lamp. It plays the role of insulating external ventilation during the use of the tungsten halogen lamp, and it is required that the lamp tube will not break or deform due to the use temperature during the use of the tungsten halogen lamp. The tungsten halogen lamp tube is made of a quartz tube that is fired and bent. Since the size of the lamp tube will affect its performance, it is necessary to measure the size parameters of the quartz lamp tube after the firing and bending, so as to ensure that the quartz bent tube meets the use standards. However, the existing measuring fixture can only measure the length or diameter, and it is difficult to detect whether the entire quartz bent tube is in the same plane, and it is not convenient to measure the bending degree and uniformity of the bent tube, which reduces the accuracy and comprehensiveness of the detection.

The measuring unit 6 includes an infrared photoresistor and a resistance value detection sensor electrically connected thereto or an infrared photodiode and a voltage value detection sensor connected thereto. The top of the measuring platform 1 is slidably connected with a parameter measuring module 8, and the front of the parameter measuring module 8 is slidably connected to the back of the infrared light detection unit 6. The parameter measuring module 8 includes a moving frame 9 slidably connected to the back of the infrared light detection unit 6. A connecting frame 11 is installed on the top of the moving frame 9. A step plate 12 is installed on the front of the measuring platform 1. A servo motor 13 is installed on the top of the step plate 12. The step plate 12 is a servo motor. The servo motor 13 provides an installation position, the output end of the servo motor 13 is connected to a screw rod 14, the screw rod 14 is arranged in the horizontal direction of the measuring platform 1, and the connecting frame 11 is sleeved on the outer wall of the screw rod 14, the top of the step plate 12 is installed with a convex strip, and the convex strip is embedded in the bottom of the connecting frame 11, and the convex strip provides a limit and guide for the connecting frame 11, the back of the moving frame 9 is installed with a laser transmitter 10, the inside of the measuring plate 5 is installed with a servo motor 2 17, the output end of the servo motor 2 17 is connected to a screw rod 2 18, and the outer wall of the screw rod 2 18 is sleeved with a parameter measurement module 2 15, the parameter measurement module 15 includes a moving block 16 embedded in the top of the measuring platform 1, and a photosensitive sensor 20 and an infrared light generator 19 are installed on the front of the moving block 16. The infrared light generator 19 is located below the photosensitive sensor 20, and the infrared light generator 19 is electrically connected to the photosensitive sensor 20.

The infrared light generator 19 is used to generate infrared light along the top of the measuring platform 1 to the parameter measurement module 8, and the photosensitive sensor 20 is used to receive the laser emitted by the laser emitter 10.

[0027] Furthermore, when the overall length of the quartz bend tube is qualified, the laser emitter 10 and the servo motor 17 are started through the control console, and the servo motor 17 drives the screw 18 to rotate, so that the parameter measurement module 15 moves to the right along the slide groove on the top of the measuring platform 1. When the photosensitive sensor 20 on the front of the parameter measurement module 15 detects that it has received the laser light emitted by the laser emitter 10 on the back of the parameter measurement module 18, the infrared light generator 19 in the parameter measurement module 15 is started, and infrared light is emitted forward along the top of the measuring platform 1, and the laser emitter 10 in the parameter measurement module 18 is turned off. Closed, the moving block 16 continues to slide to the right, and measures whether it receives infrared light through the infrared light detection unit 6, and then determines whether the bottom of the quartz elbow is in contact with the top of the measuring platform 1. For example, when the infrared light detection unit 6 receives infrared light, it means that there is a gap between the bottom of the elbow and the top of the measuring platform 1. The bottom of the elbow may have bulges, the fillet of the elbow may be tilted upward or downward, the large arc part of the elbow may be arched or concave, and the entire elbow may not be coplanar, resulting in the quartz elbow being unqualified. By setting the coplanar measurement component 2, the overall coplanarity of the quartz elbow can be measured, thereby improving the detection accuracy of the quartz elbow.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 An embodiment of the present invention is as follows: a multi-parameter detection device for a quartz bend tube, wherein a T-shaped bracket 25 on the top of a measuring platform 1 is located behind a coplanar measuring component 2, a vertical electric push rod 26 is installed on the top of the T-shaped bracket 25, and an output end of the vertical electric push rod 26 is connected to a degree measuring component 4, and the degree measuring component 4 is located above the measuring platform 1, and the degree measuring component 4 includes a lifting plate 27, and a standard detection arc plate 28 is detachably installed at the bottom of the lifting plate 27, and the standard detection arc plate 28 is composed of a large arc plate with a known radius and a center of a circle, small arc plates with known arc angles on both sides of the large arc plate, and a horizontal plate, and the standard detection arc 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 2 30 and a spring 2 31 are installed on the top of the lifting block 29, and the spring 2 31 is located on both sides of the pressure sensor 2 30, a distance sensor 2 32 is embedded in the bottom of the lifting block 29, and the distance sensor 2 32 is used to detect the distance from its own bottom to the top of the measuring table 1, and a plurality of sets of distance sensors 33 are embedded on the front side of the standard detection arc plate 28, and the distance sensor 3 33 is used to measure the distance from the front side of the standard detection arc plate 28 to the outer wall of the curved pipe.

[0029] Furthermore, after the coplanar measurement component 2 detects the overall coplanarity of the curved tube, the vertical electric push rod 26 extends to push the standard detection arc plate 28 downward. When the lifting block 29 at the bottom of the standard detection arc plate 28 is squeezed and the detection data of the pressure sensor 2 is not 0, the distance sensor 2 32 is started 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 not 0, it means that the bottom of the lifting block 29 is located at the top of the measuring platform 1 and fits well, indicating that the standard detection arc plate 28 cannot be stuck on the outside of the quartz curved tube. The quartz curved tube may have an excessive longitudinal length, an insufficient bending of the large arc segment of the curved tube, an excessive bending of the small arc segment, and a straight curved tube. If the diameter is too large, the detected bent pipe is an unqualified product. When the measurement data obtained by the distance sensor 2 32 is 0, the distance from the front wall of the standard detection arc plate 28 to the back of the bent pipe is measured by the distance sensor 3 33. When the measurement value obtained by the distance sensor 3 33 is not 0, it means that the front wall of the standard detection arc plate 28 is not in contact with the back of the bent pipe. The bent pipe may have a longitudinal length that is too small, the large arc segment is excessively bent, and the small arc segment is not bent enough. In this case, the detected bent pipe is an unqualified product. By setting the degree measurement component 4, the bending degree, tube diameter and longitudinal length of the arc segment of the bent pipe can be detected, which is beneficial to improving the detection accuracy and comprehensiveness of the quartz bent pipe.

The control console 49 is provided with a measurement standard value B3 of the pressure sensor 37, B3 is 1N, and when the force between the measuring rod 36 and the elbow is less than the standard measurement value B3, the measurement elbow 36 will not cause the elbow to be broken, scratched on the surface, and other damage. The uniform measurement component 3 also includes a mounting seat 39 detachably arranged on the top of the lifting plate 27, the mounting seat 39 is embedded in the top of the lifting plate 27, and the mounting seat 39 is slidably connected to the embedded connection of the lifting plate 27, and the mounting seat 39 is located on the sliding seat 35 On the front side, a servo motor 3 40 is arranged on the top of the mounting seat 39, and the axis of the output end of the servo motor 3 40 is located above the center of the large arc portion of the standard quartz curved tube, and the output end of the servo motor 3 40 is connected to a rotating seat 41, a fixed rod 42 is installed on the back of the rotating seat 41, a telescopic rod 43 is installed through the back of the fixed rod 42, an electromagnet 44 is installed at the front end of the telescopic rod 43, an 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 sleeve 47 is installed at the rear end of the telescopic rod 43, and the ring sleeve 47 is sleeved on the outer wall of the measuring round rod 36, and the ring sleeve 47 is fixedly connected to the outer wall of the measuring round rod 36, The ring sleeve 47 is located above the distance measuring sensor four 38, and a force sensor 48 is provided 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 micro electric push rod 45 is installed on the top of the sliding seat 35, and the micro electric push rod 45 is located below the lifting plate 27. The output end of the micro electric push rod 45 is connected to a plug rod 46, and the plug rod 46 passes through the front of the sliding seat 35 and the outer wall of the measuring round rod 36. The plug rod 46 is used to fix the measuring round rod 36, and when the measuring round rod 36 is fixed, it is located on the middle symmetry line of the standard detection arc plate 28. The electromagnet 44, the pressure sensor three 37 and the micro electric push rod 45 are electrically connected.

[0031] Furthermore, after the degree measuring component 4 is detected, the horizontal electric push rod 34 shortens and pulls the sliding seat 35 to drive the measuring round rod 36 to move backward. At this time, the sliding seat 35 and the measuring round rod 36 are fixed by the insertion rod 46, and the electromagnet 44 is in an unpowered state. The measuring round rod 36 moves forward until the pressure sensor three 37 fits with the front side wall of the bent pipe. When the measurement value obtained by the pressure sensor three 37 is between 0 and B3, the sliding seat 35 stops moving. At the same time, the back side of the measuring round rod 36 fits with the front side wall of the bent pipe. The bent pipe detects the distance from the outer wall of the measuring round rod 36 to the standard detection arc plate 28 through the distance measuring sensor four 38, thereby obtaining the diameter of the large arc part of the quartz bent pipe, and at the same time obtains the measurement data of the force sensor 48. After that, the micro electric push rod 45 extends, driving the insertion rod 46 to move forward, separating the insertion rod 46 from the measuring round rod 36, and energizing the electromagnet 44, thereby relative to the fixed The rod 42 fixes the position of the telescopic rod 43, and the servo motor three 40 drives the rotating seat 41 to rotate. The rotating seat 41 drives the measuring circular rod 36 to rotate to the right through the fixed rod 42, the telescopic rod 43 and the ring sleeve 47. When the data of the force sensor 48 increases or the measurement data of the pressure sensor three decreases during the rotation, the large arc part of the surface of the bent pipe may be convex or concave, making the actual diameter of the bent pipe uneven. Then the servo motor three 40 reverses and drives the measuring circular rod 36 back to its original position, and then drives the measuring circular rod 36 to rotate to the left again, so that the measuring circular rod 36 can realize the detection within the standard angle range corresponding to the standard arc segment of the bent pipe, thereby improving the accuracy of the bent pipe detection result and avoiding the existence of blind spots in detection. After the use of the measuring circular rod 36 is over, it is rotated to its original position, and the insertion rod 46 is pulled backward by the micro electric push rod 45 to fix the measuring circular rod 36.

[0032] Working principle: The multi-parameter detection equipment for quartz bent tubes, by setting a coplanar measurement component 2, uses a movable parameter measurement module 1 8 to detect the overall lateral length dimension of the bent tube, uses a parameter measurement module 2 15 to emit infrared light forward, and uses the infrared light detection component to detect whether the front of the bent tube itself is irradiated with infrared light, and then detects whether the entire bent tube is on the same plane. By using a standard detection arc plate 28, the bending degree, tube diameter and longitudinal length dimension of the arc segment of the bent tube are detected, which is beneficial to improving the detection accuracy and comprehensiveness of the quartz bent tube. By measuring the round rod 36 to detect the diameter of the large arc segment of the bent tube and whether it is uniform, various types of bent tubes are detected, thereby achieving the purpose of comprehensive detection of quartz bent tubes and improving the detection accuracy and comprehensiveness of quartz bent tubes.
