Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing, and in particular to a device for assisting in the assembly of laser components for sensors. Background Technology

[0002] In the manufacturing process of distance sensors, the laser emitter, focusing lens and laser receiver are usually integrated inside the housing, and the laser is emitted and received through the light-transmitting window on the housing.

[0003] To ensure sensor accuracy, the optical system of the transmitter and lens needs to be precisely adjusted during the assembly stage: by projecting the emitted laser beam through the lens onto the spot analyzer, the axial distance, elevation angle and horizontal deflection angle between the transmitter and the lens are adjusted in sequence until the spot shape and energy distribution reach the preset standard, and finally the optical components are fixed. Currently, the debugging process mainly relies on manual operation. Since optical adjustment needs to be completed within the range of micrometer-level displacement and milliradian-level angle, manual adjustment is not only difficult to accurately control minute changes, but repeated adjustments are also prone to introducing human error, which significantly restricts the accuracy and efficiency of optical alignment. Utility Model Content

Through the coordinated action of multiple mechanisms, the axial distance, elevation angle, and horizontal deflection angle between the transmitter and the lens are automatically adjusted, thereby improving alignment accuracy and assembly efficiency.

[0013] The beneficial effects of the device disclosed in this utility model for assisting in the assembly of sensor laser components are: The operator clamps the transmitter onto the first fixture, while the lens and receiver are clamped onto the fixture via the second fixture, so that the lens is positioned between the transmitter and the spot analysis device, and the receiver is positioned on the laser reflection path. The two-dimensional driving mechanism drives the emitting end to approach the lens, and the emitting end emits laser light. After the beam is transmitted through the lens, it illuminates the spot analysis device, and the reflected laser light is received by the receiving end.

[0025] Please refer to Figure 1 , Figure 2 and Figures 4-6 .

[0026] The fixture 5 is placed on the table surface of the workbench 1 and fixedly connected thereto; the fixture 5 is provided with a second clamp 6, and the fixture 5 and the second clamp 6 are used to clamp the lens 82 and the receiving end 83. The lens 82 is located between the transmitting end 81 and the spot analysis device. Furthermore, a template 51 is fixedly connected to the fixture 5.

A contact block 622 is fixedly connected to the other end of the connecting rod 621.

The contact block 622 abuts against one of the limiting plates, and a nut is connected to the thread, which abuts against the other limiting plate. The rocker arm 62 rotates at a certain angle on the connecting seat 61, so that the contact block 622 at the other end of the rocker arm 62 touches the lens 82 and the receiving end 83; by loosening the nut, the friction between the two limiting plates and the rocker arm 62 is reduced, and the connecting rod 621 is pulled to slide in the mounting groove, changing the position of the contact block 622 on the rocker arm 62 to adapt to lenses 82 of different specifications; at the same time, it is necessary to attach or remove the shims on the contact block 622 so that the contact block 622 can touch the receiving end 83; Furthermore, one end of the connecting rod 611 is rotatably connected to the connecting seat 61, and the connection point between the connecting rod 611 and the connecting seat 61 is located on the other side of the recess. The other end of the connecting rod 611 is rotatably connected to the lever 63, and the connection point between the connecting rod 611 and the lever 63 is located in the middle of the lever 63. One end of the lever 63 is rotatably connected to the middle of the rocker arm 62.

The other end of connecting rod 611 is located in the recess, and both rocker arm 62 and lever 63 are in a horizontal state, so that contact block 622 touches lens 82 and receiving end 83, constraining lens 82 and receiving end 83 on fixture 5. By rotating lever 63 on connecting rod 611, the rocker arm 62 and connecting rod 611 are simultaneously pulled to rotate on connecting seat 61, so that contact block 622 moves away from the top of lens 82 and receiving end 83, and the other end of connecting rod 611 disengages from the recess. The middle part of rocker arm 62 and one end of lever 63 are both located in the recess, releasing the constraint on lens 82 and receiving end 83.

[0029] A traveling device 7 is fixedly connected to the table surface of the workbench 1. In this embodiment, the traveling device 7 is preferably a ball screw device. A traveling slide plate 71 is slidably connected to the traveling device 7. A spot analysis device 711 is fixedly connected to the traveling slide plate 71. In this embodiment, the spot analysis device 711 is preferably a spot analyzer. The traveling device 7 drives the traveling slide plate 71 to slide back and forth along the X-axis, thereby driving the spot analysis device to move closer to or away from the lens 82, so as to detect lasers at different distances.

[0030] Please refer to Figures 1-6 .

[0031] At runtime: The operator clamps the transmitter 81 onto the first clamp 43; the receiver 83 is pre-fixed on the fixture 5, and the lens 82 is close to the adjusting slide plate 52; by moving the lever 63, it is driven to rotate on the connecting rod 611, which simultaneously pushes the rocker arm 62 and the connecting rod 611 to rotate in the connecting seat 61. At this time, the other end of the connecting rod 611 is located in the recessed structure, and the rocker arm 62 and the lever 63 are both in a horizontal state, so that the contact block 622 presses against the lens 82 and the receiver 83, thereby stably constraining the two on the fixture 5. The X-axis lead screw device 21 drives the connecting seat 211 to move towards the fixture 5, bringing the emitting end 81 closer to the lens 82. At the same time, the emitting end 81 is powered on, so that the emitted laser passes through the lens 82 and the light window 511 in sequence and shines on the spot analysis device. The reflected laser is collected by the receiving end 83. The spot analysis device detects the laser at different transmission distances. If defects are found in the spot shape or energy distribution, the elevation lead screw device 31 drives the elevation slide plate 32 to adjust the elevation angle, and the angle lead screw device 41 drives the angle slide plate 42 to adjust the horizontal angle. Together, they adjust the orientation of the emitting end 81 relative to the lens 82 to optimize the laser output characteristics. After the laser defects are improved, the operator uses an adhesive dispensing process to fix the lens 82 to the transmitter 81. Then, the transmitter 81 and lens 82, which have been calibrated and fixed, are removed from the first fixture 43 and the second fixture 6, respectively, to complete the entire calibration and assembly process.

[0032] This utility model provides a device for assisting in the assembly of laser components for sensors. The operator clamps the transmitter onto the first fixture, while the lens and receiver are clamped onto the fixture via the second fixture, so that the lens is located between the transmitter and the spot analysis device, and the receiver is located on the laser reflection path. The two-dimensional driving mechanism drives the emitting end to approach the lens, and the emitting end emits laser light. After the beam is transmitted through the lens, it illuminates the spot analysis device, and the reflected laser light is received by the receiving end. The spot analysis device detects the laser light. If defects are found in the shape or energy distribution of the laser spot, the elevation adjustment mechanism adjusts the elevation angle of the emitting end relative to the lens according to the detection results, and the angle adjustment mechanism adjusts its horizontal deflection angle to optimize the laser output characteristics. After the laser defects are improved, the operator fixes the lens to the transmitter by applying adhesive. Then, the assembled transmitter and lens are removed from the first and second clamps. Through the coordinated adjustment of the pitch adjustment mechanism and the angle adjustment mechanism, the angle of the transmitter toward the lens is automatically adjusted with high precision, which effectively improves the debugging accuracy and work efficiency.
