Description

Technical Field

[0002] Laser detection is a method of measuring, detecting and analyzing using laser technology. It uses the high-intensity, monochromatic and coherent laser beam generated by the laser to interact with the target object, and obtains information about the target object by measuring the interaction process between the laser and the target object. Laser detection can be applied to many fields, including industry, medicine, environmental monitoring, communications, etc. In the industrial field, laser detection can be used to measure physical parameters such as distance, speed, shape, surface roughness, size, etc., for quality control, automated production and precision machining, etc. Optical components in laser detection play a vital role.

[0004] The above cited patent still has certain defects in actual use, that is, the laser detector in the document and the second threaded block in the adjustment mechanism are fixedly installed. In actual use, since different laser sources have different wavelength and power characteristics, the fixedly installed laser detector is only suitable for laser detection in a specific wavelength or power range.

At the same time, the detection and calibration platform lacks a positioning mechanism for the workpiece, which makes it easy for the workpiece to be offset during positioning, resulting in differences in the calibration data. Therefore, an optical element for laser detection is proposed to solve the above problems. Utility Model Content

[0026] Two sets of first linear screw modules 2 are arranged in parallel along the transverse direction on the upper end surface of the detection and calibration platform 1; a laser detection base 3 is assembled on the two sets of first linear screw modules 2, and a plurality of workpiece clamping components 4 are arranged in an array on the upper end surface of the laser detection base 3;

[0027] Two sets of vertical frames 5 are vertically supported on the upper end surface of the detection and calibration platform 1, a second linear screw module 6 is horizontally arranged between the two sets of vertical frames 5, a third linear screw module 7 is slidably assembled on the second linear screw module 6, the third linear screw module 7 is vertically arranged to the moving direction of the second linear screw module 6, a mounting platform 8 is assembled on the third linear screw module 7, an optical element positioning mechanism 9 is installed on one side of the mounting platform 8; a laser optical element body 10 is clamped in the optical element positioning mechanism 9;

[0028] The optical element positioning mechanism 9 includes an L-shaped seat 91 arranged on the side of the mounting platform 8, an adjustment seat 93 is fixedly provided on one side of the L-shaped seat 91, a slide groove is opened on the side of the adjustment seat 93, an adjustment plate 94 is slidably provided in the slide groove, a short screw rod 95 is rotatably provided in the adjustment seat 93, and the short screw rod 95 is meshed with the adjustment plate 94.

[0029] In the present embodiment, in actual use, through the mutual movement coordination of multiple components within the optical element positioning mechanism 9, the outer shell of the laser optical element body 10 is placed between two rubber pads 92, and then the adjustment end 97 is rotated, through the connection between the adjustment end 97 and the short screw 95, and the limiting of the limiting rods 96 on both sides, the adjustment plate 94 engaged on the outside of the short screw 95 can be moved linearly, and the side wall of the L-shaped seat 91 is cooperated to finally realize the clamping and positioning of the laser optical element body 10. Through the clamping movement of the optical element positioning mechanism 9 and the buffering wrapping of the rubber pad 92, the optical element positioning mechanism 9 can adapt to the assembly and use of different types of optical elements. Compared with the fixed assembly method in the cited documents, the optical element for laser detection of the present application is more convenient and easy to adjust when replaced.

[0030] Specifically, refer to Figure 1-2 , Figure 4 One end of the short screw rod 95 passes through the side wall of the adjustment seat 93 and extends to the outside and is connected to the adjustment end 97. Two limit rods 96 are also arranged in parallel in the adjustment seat 93. The two limit rods 96 are respectively arranged on one side of the adjustment plate 94 and pass through the adjustment plate 94.

[0031] In this embodiment, in actual use, the user rotates the adjustment end 97, through the connection between the adjustment end 97 and 75, and cooperates with the limiting of the limiting rods 96 on both sides, so that the adjustment plate 94 engaged on the outside of the adjustment end 97 can move linearly in the adjustment seat 93. Through the movement control of the adjustment plate 94, the set optical element positioning mechanism 9 can be adapted to the clamping of optical elements of different sizes, and has a wider range of applications.

[0032] Specifically, refer to Figure 1-2 , Figure 4 A rubber pad 92 is adhered to the vertical side wall of the L-shaped seat 91 and the opposite side of the adjustment plate 94 , and the laser optical element body 10 is clamped between the two rubber pads 92 .

[0033] In this embodiment, in actual use, the user controls the linear movement of the adjustment plate 94 so that the adjustment plate 94 can cooperate with the side wall of the L-shaped seat 91 to clamp the laser optical element body 10. At this time, the two groups of rubber pads 92 will contact the outer shell of the laser optical element body 10 and clamp the laser optical element body 10 inside. By clamping the laser optical element body 10 with the two groups of rubber pads 92 arranged opposite to each other, the rubber pads 92 can clamp and buffer the outer shell of the optical element. At the same time, the rubber pads 92 have good friction properties. When the two groups of rubber pads 92 clamp the laser optical element body 10, the friction between the rubber pads 92 and the outer shell of the optical element can be increased to prevent the optical element from sliding or shifting.

[0034] Specifically, refer to Figure 1-3 Several workpiece clamping assemblies 4 all include a positioning plate 41 arranged on the upper end surface of the laser detection base 3, and positioning bolts 42 are provided at the four corners of the positioning plate 41. The positioning plate 41 is detachably arranged on the upper end surface of the laser detection base 3 through the positioning bolts 42, and the upper end surface of the positioning plate 41 is detachably assembled with a fixed block 43 through a bolt member.

[0035] In this embodiment, the positioning bolts 42 arranged at the corners of the positioning plate 41 can be used to assemble the workpiece clamping assembly 4 on the upper end surface of the laser detection base 3, so that the user can assemble the workpiece on the laser detection base 3, and the set block 43 can be used to press one side of the workpiece.

[0036] Specifically, refer to Figure 1-3 A cross slot 44 is provided on the upper end surface of the positioning plate 41 in the transverse direction, a cross slider 45 is slidably fitted in the cross slot 44, a slide seat 46 is provided on the upper end surface of the cross slider 45, and clamping notches 461 are provided on the opposite sides of the slide seat 46 and the fixed block 43.

[0037] In this embodiment, when the cross slide 45 slides in the cross slide groove 44, the slide 46 arranged on the upper end surface of the cross slide 45 will move with the cross slide 45. When the user places the workpiece between the slide 46 and the fixed block 43, the two sides of the workpiece can be clamped by cooperating with the fixed block 43 to realize the assembly of the workpiece, and the clamping notch 461 opened on the side of the slide 46 and the fixed block 43 can further ensure that the workpiece will not move during clamping. The opening shape of the clamping notch 461 can also be replaced with a semicircular notch, thereby realizing the clamping of the cylindrical workpiece by the slide 46 and the fixed block 43. The fixed block 43 and the slide 46 can be customized by non-standard ways to open the notch shapes on their sides.

[0038] Specifically, refer to Figure 1-3 Bearing seats are provided at both ends of the positioning plate 41, and a small threaded rod 47 is rotatably provided between the two bearing seats. The small threaded rod 47 is meshed with the cross slider 45, and one end of the small threaded rod 47 passes through one of the bearing seats and extends to the outside and is connected to an adjusting shaft 48.

[0039] In this embodiment, in actual use, the user places the workpiece on the workpiece clamping assembly 4, and rotates the set adjustment shaft 48 to rotate the set small threaded rod 47. Through the engagement between the small threaded rod 47 and the cross slider 45, the user controls the movement of the slide 46 to separate the distance between the fixed block 43 and the small threaded rod 47. Similarly, when the user rotates the adjustment shaft 48 in the opposite direction, the set cross slider 45 will drive the slide 46 to move to one side of the fixed block 43. The bearing seats set at both ends of the positioning plate 41 can ensure the stability and smoothness of the small threaded rod 47 during rotation.

[0040] The optical element for laser detection of the utility model:

[0041] Step 1: When using the laser optical element body 10, first assemble the laser optical element body 10 on the optical element positioning mechanism 9, by placing the outer shell of the laser optical element body 10 between the rubber pads 92, and then rotating the adjustment end 97, through the connection between the adjustment end 97 and 75, in cooperation with the limiting rods 96 on both sides, the adjustment plate 94 engaged on the outside of the adjustment end 97 can move linearly, and in cooperation with the side wall of the L-shaped seat 91, the clamping and positioning of the laser optical element body 10 is finally achieved. The user controls the center point of the laser optical element body 10 to face vertically downward, and then assembles the laser optical element body 10 through the optical element positioning mechanism 9;

[0042] Step 2: During use, the user places the workpiece on the workpiece clamping assembly 4, and rotates the set adjustment shaft 48 to rotate the set small threaded rod 47. Through the meshing between the cross slider 45 and the small threaded rod 47, the cross slider 45 can drive the slide 46 to move synchronously. At this time, the user controls the movement of the slide 46 to separate the spacing between the fixed block 43 and the small threaded rod 47. Then the user places the workpiece to be processed between the fixed block 43 and the small threaded rod 47. After the workpiece is placed, the adjustment shaft 48 is rotated in the opposite direction again to rotate the set small threaded rod 47 in the opposite direction. At this time, the slide 46 can move toward one side of the fixed block 43 until it cooperates with the fixed block 43 to clamp the workpiece; the user assembles the workpieces on several groups of workpiece clamping assemblies 4 in turn, and then drives the first linear screw module 2 to linearly drive the laser detection base 3;

[0043] Step 3: The user controls the first linear screw module 2 to linearly drive the laser detection base 3, so that it drives several groups of workpiece clamping assemblies 4 and the workpieces located on the workpiece clamping assemblies 4 to move to the bottom of the laser optical element body 10, and then controls the dual-axis linear position of the second linear screw module 6 and the third linear screw module 7, so that the mounting table 8 that can perform XY axial movement drives the laser optical element body 10 for mobile monitoring, and cooperates with the set laser detection base 3 to linearly drive the workpiece, and finally realizes laser detection of the workpiece in the three-axis position.
