Description

Technical Field

[0001] The invention belongs to the technical field of laser sensor measurement equipment, in particular to a laser sensor fixing plate for adjusting the degree of freedom and posture. Background Art

[0002] Laser sensing metrology equipment, as a core metrology device characterized by optical methods, is widely used in fields such as industrial automation. For example, in industrial automation production lines, laser sensors perform real-time, high-precision inspection of continuously conveyed workpieces (such as body frames in automotive welding stations, precision components in consumer electronics assembly lines, or high-speed conveyed materials in packaging production lines). Quality control is achieved through laser ranging, 3D contour scanning, or surface defect identification. In such scenarios, a degree-of-freedom posture adjustment mechanism is usually required to adjust the spatial position of the laser sensor to achieve precise positioning and inspection of the optical sensing element. However, in current use, although the degree-of-freedom posture adjustment mechanism can achieve spatial position adjustment of the laser sensor, in actual production line applications, the sensor is exposed to complex working conditions with superposition of vibration, dust and temperature rise for a long time, and its optical performance stability faces multiple challenges. The traditional heat dissipation design relies on open passive heat dissipation holes, which can easily cause unstable optical path collimation. In addition, the diffusion of dust on the production line causes a negative pressure adsorption effect at the detection window, which accelerates the accumulation of dust particles on the sensor lens or optical path surface, causing light scattering errors. The posture adjustment mechanism only focuses on the initial positioning accuracy and lacks the coupling effect on heat dissipation and dust prevention issues, which restricts the reliability of laser sensors in high-precision detection scenarios. Therefore, a degree of freedom posture adjustment laser sensor fixing plate is proposed to solve the above problems. Summary of the Invention

[0009] In the above technical solution, preferably, the filter element includes a filter plate arranged in the air duct and a pull plate passing through the air duct and connected to the filter plate, and the pull plate is provided with a magnetic sheet that is magnetically attracted to the air duct.

At the same time, the air inlet end of the air guide passage absorbs dust-laden air toward the periphery of the detection end, and after filtration, forms a clean airflow that is directed toward the heat dissipation port. This not only removes dust from the detection end through negative pressure adsorption, but also physically isolates the dust intake path from the heat dissipation airflow path, ultimately achieving a synergistic effect of improving heat dissipation efficiency and optimizing dust-proof performance. The rotational power of the rotating impeller is further converted into the circumferential reciprocating swing of the wind guide plate through motion conversion parts (such as eccentric wheels, tooth plates and gear linkage mechanisms), so that the airflow in the air guide cavity forms a dynamic heat dissipation pattern that alternately sweeps different areas of the heat dissipation port, which not only improves the uniformity of heat dissipation, but also achieves self-powered power without the need for an additional drive source.

[0015] At the same time, the energy is transmitted to the dust collection sleeve through linear reciprocating drive components (such as reciprocating screws and moving plates), driving the cleaning pad to slide back and forth periodically along the periphery of the detection end. Cooperating with the timing trigger mechanism of the time-controlled switch, it actively absorbs and scrapes off the attached dust, avoiding scattering errors caused by dust accumulation in the optical path of the detection end, and simultaneously achieving the dual optimization of enhanced heat dissipation efficiency and dust interference suppression.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention provides a degree of freedom posture adjustment laser sensor fixing plate, including a laser sensor 1, and further comprising: A multi-axis position adjustment mechanism 2, connected to the laser sensor 1, for adjusting the spatial position of the laser sensor 1; The air guide sleeve 3 is sleeved on the periphery of at least one side of the heat dissipation opening 4 of the laser sensor 1; The rotating impeller 5 is rotatably disposed in the air guide sleeve 3; The air guide passage 6 has an air outlet connected to the air guide sleeve 3 and an air flow direction guided out of the communication end is consistent with the circumferential tangent direction of the rotating impeller 5, driving the rotating impeller 5 to rotate circumferentially; The air inlet end of the air guide passage 6 opens toward the peripheral side of the detection end of the laser sensor 1 , and is used to absorb and guide dust particles at the detection end and filter them within the air guide passage 6 .

[0020] In the above scheme, the rotating impeller 5 is driven by the airflow of the air guide passage 6 to form a rotating negative pressure field. While actively adsorbing dust particles in the detection area, a directional airflow is formed through the air guide sleeve 3 to accelerate the heat exchange of the heat dissipation port 4, so that the sensor can still maintain measurement accuracy under high temperature and dust conditions.

[0021] like Figure 3 As shown, it also includes: The air distribution mesh plate 7 divides the air guide sleeve 3 into an assembly chamber 31 and an air guide chamber 32 which are connected to each other; The outlet end of the air guide passage 6 is connected to the assembly chamber 31, and the rotating impeller 5 is arranged in the assembly chamber 31; The wind guide plate 8 is rotatably disposed in the wind guide cavity 32 to guide the wind to blow toward the heat dissipation outlet 4.

[0022] A graded airflow control system is formed by using the air distribution mesh plate 7 and the wind guide plate 8. Through the layered guide design of the assembly cavity 31 and the air guide cavity 32, the airflow generated by the rotating impeller 5 and the heat dissipation airflow are physically isolated and synergistically enhanced. The air distribution mesh plate 7 can convert the turbulent flow of the rotating impeller 5 into laminar flow, ensuring that the heat dissipation airflow of the guide plate 8 in the air guide cavity 32 covers the fin gap of the heat dissipation port 4, thereby improving the heat dissipation efficiency.

[0023] like Figure 3 、 Figure 4 、 Figure 9 As shown, it also includes: The motion conversion member 9 is connected to the shaft end of the rotating impeller 5 and the shaft end of the wind deflector 8 respectively; As the impeller 5 rotates, the motion conversion member 9 drives the wind deflector 8 to rotate back and forth in a circumferential direction. The wind deflector 8 rotates back and forth in a circumferential direction to alternately guide the airflow to different areas of the heat dissipation outlet 4 .

[0024] The motion conversion element 9 includes: The eccentric wheel 91 is disposed in the air guide cavity 32 and is fixedly connected to the shaft end of the rotating impeller 5; The driving cavity plate 92 has an accommodating cavity for accommodating the eccentric wheel 91; The eccentric wheel 91 drives the cavity plate 92 to move back and forth along the guide rail through eccentric motion; The tooth plate 93 is fixed on the driving cavity plate 92; The gear 94 is fixedly mounted on the outer side of the shaft end of the wind deflector 8 and meshes with the gear plate 93 .

[0025] Through the mechanical linkage of the eccentric wheel 91 and the toothed plate 93-gear 94, the continuous circumferential motion of the rotating impeller 5 is converted into the periodic reciprocating swing of the wind guide plate 8, thereby achieving dynamic area coverage of the heat dissipation airflow. The traditional servo motor drive solution is replaced by a purely mechanical structure, and the airflow sweep area of the heat dissipation port 4 is increased without additional energy consumption, thereby eliminating local high-temperature dead corners between heat dissipation areas.

[0026] Furthermore, the above solution can be designed with a double-layer motion conversion member 9 and a wind deflector 8 structure according to actual needs, and can realize the blowing direction along the upper and lower / left and right directions respectively. This is not shown in the drawings of the specification, and it can also be set and realized as needed; like Figure 5 、 Figure 6 、 Figure 7 、 Figure 10 As shown, the air guide passage 6 includes an air guide pipe 61 and an air guide fan 62. A filter 63 is provided in the air guide pipe 61 and on the air inlet side of the air guide fan 62. The air inlet end of the air guide pipe 61 is connected to a dust collection cover 64, and the air outlet end of the air guide pipe 61 is connected to the air guide cover 3 through a hose 65.

[0027] The filter element 63 includes a filter plate 631 disposed in the air duct 61 and a pull plate 632 penetrating the air duct 61 and connected to the filter plate 631 . A magnetic sheet 633 is provided on the pull plate 632 and is magnetically attracted to the air duct 61 .

[0028] The adsorption and positioning structure of the magnetic plate 633 and the air guide tube 61 allows the filter plate 631 to be quickly pulled out and cleaned without disassembling the pipeline. This, combined with the pressurization effect of the air guide fan 62, also avoids the wear and leakage of the sealing surface caused by traditional threaded fixings. like Figure 5 、 Figure 12 As shown, the dust collection sleeve 64 includes a sliding sleeve 641 and a hole sleeve 642, wherein: The sliding sleeve 641 is slidably mounted on the outer periphery of the air guide tube 61; The hole sleeve 642 is fixedly connected to the end of the sliding sleeve 641 and communicates with the air guide tube 61 and the inner cavity of the hole sleeve 642; A cleaning pad 643 is provided on the hole sleeve 642. The working surface of the cleaning pad 643 is coplanar and parallel to the detection end of the laser sensor 1. An air inlet hole 644 is provided on the hole sleeve 642. It also includes a linear reciprocating drive member 66, the output end of which is transmission-connected to the sliding sleeve 641, and is used to drive the hole sleeve 642 to drive the cleaning pad 643 to reciprocate axially between the first position and the second position, so that the cleaning pad 643 contacts and wipes the detection end surface of the laser sensor 1 during the movement, and the first position and the second position are respectively located on both sides of the detection end of the laser sensor 1.

[0029] The linear reciprocating drive member 66 includes a transmission motor 661 provided on the multi-axis position adjustment mechanism 2. A reciprocating screw 662 is provided at the output end of the transmission motor 661. A movable plate 663 that moves along the sliding rod is threadedly connected to the reciprocating screw 662. The movable plate 663 is connected to the sliding sleeve 641. It also includes a time control switch 664, which is electrically connected to the transmission motor 661 and is used to control the start and stop of the transmission motor 661 according to preset time parameters; When the set time threshold is reached, the transmission motor 661 drives the reciprocating screw 662 to rotate, driving the moving plate 663 and the sliding sleeve 641 to perform a periodic displacement action.

[0030] Through the timing control of the sliding sleeve 641 and the linear reciprocating drive member 66 combined with the time-controlled switch 664, the automatic cleaning of the dust on the detection end surface of the laser sensor 1 is achieved. The coplanar configuration of the cleaning pad 643 and the detection end and the periodic axial displacement action can simultaneously remove the residual adhered particles on the edge of the detection end without interrupting the detection operation, thereby preserving the cleanliness of the mirror.

[0031] like Figure 8 As shown, there are two air guide sleeves 3 and they are respectively located on the opposite sides of the laser sensor 1. A clamping plate 10 is provided on the air guide sleeve 3. A bidirectional screw 11 rotatably arranged on the multi-axis position adjustment mechanism 2 is connected between the clamping plates 10 on both sides. A rubber sleeve 12 is provided on the side of the air guide sleeve 3 facing the heat dissipation port 4. As the bidirectional screw 11 drives the clamping plates 10 on both sides, the air guide sleeve 3 moves toward the laser sensor 1 to fix the position of the laser sensor 1, and the rubber sleeve 12 fits the outer periphery of the heat dissipation port 4.

[0032] The laser sensor 1 is quickly installed and the heat dissipation port 4 is sealed and adapted through the bidirectional screw 11 and the symmetrical clamping plate 10. At the same time, the rubber sleeve 12 elastically deforms under pressure and fits tightly to the special-shaped edge of the heat dissipation port 4, achieving a dual effect of dustproofing and sealing.

[0033] like Figure 1 As shown, the multi-axis position adjustment mechanism 2 includes an X linear axis 21, a Y linear axis 22, a Z linear axis 23 and a C rotation axis 24, and the laser sensor 1 is arranged on the C rotation axis 24; Specifically, the above-mentioned multi-axis specific operation process is a conventional technology, so it is not described in detail, and the above-mentioned multi-axis can be used by adding or removing other position axes according to actual needs.

[0034] The working principle and use process of the present invention: The bidirectional screw 11 rotates to drive the clamping plates 10 on both sides to drive the air guide sleeve 3 to clamp the laser sensor 1, and the rubber sleeve 12 fits tightly against the heat dissipation port 4 to complete the position fixing operation; Then, the X linear axis 21, Y linear axis 22, Z linear axis 23 and C rotary axis 24 of the multi-axis position adjustment mechanism 2 are used to adjust the precise position of the laser sensor 1 on the X / Y / Z linear axes and C rotary axis, and the laser sensor 1 is moved to the transmission line or the inspection position for detection and measurement. Then, the fan 62 of the air guide passage 6 is started, and the air flow passes through the air inlet end of the dust collection sleeve 64 to absorb the dust particles around the detection end, and is transported to the air guide sleeve 3 through the air guide pipe 61; The airflow drives the rotating impeller 5 to rotate along the tangential direction of the air guide sleeve 3. After the airflow enters the assembly cavity 31, the airflow is evenly distributed to the air guide cavity 32 through the air distribution mesh plate 7 under the rotation of the rotating impeller 5. At the same time, the shaft end of the rotating impeller 5 drives the eccentric wheel 91 to rotate, and then drives the driving cavity plate 92 and the tooth plate 93 to move back and forth in a straight line, and through the engagement of the tooth plate 93 and the gear 94, drives the wind guide plate 8 to swing periodically, optimizing the heat dissipation airflow to alternately cover different areas of the heat dissipation port 4, and realize dynamic heat dissipation operation.

[0035] During this process, the time-controlled switch 664 starts the transmission motor 661 according to a preset cycle, driving the reciprocating screw 662 to drive the movable plate 663 and the sliding sleeve 641 to move axially, so that the cleaning pad 643 wipes back and forth along the surface of the detection end, and the hole sleeve 642 sucks dust and cooperates to clean the detection end area of the laser sensor 1; Regularly pull the pull plate 632 to bring out the filter plate 631 for cleaning or replacement; adjust the bidirectional screw 11 to release the air guide sleeve 3 to replace the cleaning pad 643 or maintain the sensor, and the maintenance operation can be completed.
