Description

Technical Field

[0001] This utility model relates to the field of lidar antenna technology, and in particular to a lidar antenna screw mounting device. Background Technology

[0002] The lidar antenna is an important component of the lidar system, mainly used to transmit and receive laser signals to achieve target detection, ranging, and 3D modeling. The manufacturing of lidar antennas uses a lidar antenna screw mounting device, which includes an upper lidar mounting plate, a middle adjustment plate, and a lower base. The upper lidar mounting plate and the middle adjustment plate, as well as the middle adjustment plate and the lower base, are connected by multiple corresponding adjustment screws and connectors. Each adjustment screw is also fitted with a corresponding preload spring.

[0003] A search revealed Chinese Patent Publication No. CN106141650B, which discloses a screw mounting device. The device includes a first cavity with a first through hole and a second through hole. An ignition element is installed in the first through hole, and a propellant head is attached to the ignition end of the ignition element. The first cavity is connected to a second cavity via the second through hole. A punch is slidably connected within the second cavity, and a rotating blade is connected to the punch. An opening is formed in the second cavity along the sliding path of the punch. A die is connected to the second cavity. The design includes a screw hole connected to the opening, and an elastic element installed on the side of the die near the punch. The screw is placed inside the screw hole, and the ignition element is energized. The shock wave generated by the burning propellant pushes the punch forward at high speed, causing it to rotate. The high-speed impact of the rotating punch then propels the screw into the object. Compared to existing technologies, this patent application offers faster installation and simpler operation. However, the screw hole sealing ring has insufficient compression and design flaws, such as a shallow groove, leading to ring displacement after vibration. A U-shaped sealing groove design, combined with waterproof adhesive to fill gaps, and a waterproof cap added to the screw head, forms a double seal with the bracket surface. Traditional screw installation tools typically rely on manual operation, achieving pre-tightening by manually tightening the screw. However, manual operation is highly uncertain, easily leading to component damage and decreased assembly accuracy due to uneven force and over-tightening. Furthermore, these tools cannot precisely control the screw's installation depth and pre-tightening force, making it difficult to meet the demands of high-precision assembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a screw mounting device for laser radar antennas, which aims to improve the existing technology where traditional screw mounting tools usually rely on manual operation to achieve pre-tightening by manually tightening screws. However, manual operation has a large degree of uncertainty and is prone to damage to components and reduced assembly accuracy due to uneven force and over-tightening.

[0006] The above technical solution involves a screwdriver driving a screw held by a fixture to rotate precisely. When the screw's installation depth reaches the set value, the system detects that the preload has reached the set target value, and the controller sends a stop signal to immediately stop the movement. This allows for precise control of the screw's installation depth and preload, avoiding over-tightening and under-tightening, reducing manual intervention, improving the consistency and reliability of the assembly process, and ensuring that the screw status at key connection points of the wind-measuring radar antenna precisely meets design requirements.

[0013] As a further description of the above technical solution:

[0014] The fixing mechanism includes a connecting frame, which is equidistantly arranged on the front and rear sides of the bottom wall of the fixing plate. Multiple fixing rods are equidistantly fixed to the top wall of the connecting frame, and the fixing rods are connected to the fixing plate.

[0015] The above technical solution involves sliding the limiting groove at the bottom of the fixing plate along the outer wall of the limiting block, aligning the grooves on the left and right sides of the top wall of the fixing plate with the fixing block, stopping the sliding, rotating the buckle to allow it to enter the groove on the top wall of the fixing plate, thus fixing the fixing plate to the fixing rod.

[0016] As a further description of the above technical solution:

[0017] Multiple limiting blocks are fixedly connected at equal intervals on the front and rear sides of the outer wall of the connecting frame. The limiting blocks are slidably connected to the inner wall of the limiting groove. Mounting blocks are fixedly connected to the left and right ends of the connecting frame. Engaging components are installed on the left and right sides of the top wall of the connecting frame.

[0018] The above technical solution involves sliding the limiting groove at the bottom of the fixing plate along the outer wall of the limiting block, aligning the grooves on the left and right sides of the top wall of the fixing plate with the fixing block, stopping the sliding, and rotating the buckle to allow it to enter the groove on the top wall of the fixing plate.

Then, the sliding stops, and the buckle is rotated to enter the groove on the top wall of the fixing plate. In this way, the fixing plate is fixed to the fixing rod, forming a stable connection.

This improves the structural rigidity, prevents the equipment from shaking during operation, and avoids affecting the scanning accuracy. At the same time, it can distribute the weight of the equipment and the vibration load. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a laser radar antenna screw mounting device, including a fixing plate 1. The bottom wall of the fixing plate 1 has multiple equidistant limiting grooves 8. A mounting mechanism 2 is installed on the top of the fixing plate 1 for mounting screws. A fixing mechanism 3 is installed on the bottom of the fixing plate 1 to improve the structural strength of the device. The mounting mechanism 2 includes a bracket 207, which is fixedly connected to the rear side of the top wall of the fixing plate 1. A clamp 204 is installed on the front side of the top wall of the fixing plate 1. A top plate 2 is fixedly connected to the top of the bracket 207. 02. A drive assembly 201 is installed on the top of the top plate 202. The drive assembly 201 includes a motor 2014, which is fixedly connected to the upper middle part of the rear side of the outer wall of the top plate 202. A turntable 1 2011 is fixedly connected to the output end of the motor 2014. A turntable 2013 is rotatably connected to the front side of the top wall of the top plate 202. Turntable 1 2011 is connected to turntable 2 2013 via a belt 2012. A screwdriver 203 is fixedly connected to the bottom end of turntable 2 2013. A horizontal platform 206 is fixedly connected to the middle of the outer wall of the bracket 207. A connecting rod 205 is fixedly connected to the front side of the top wall of platform 206. The connecting rod 205 is connected to the top plate 202. During operation, the operator needs to place the screws used to fix the wind measuring radar antenna components into the clamp 204 and ensure that they are firmly clamped. Through the controller 5, according to the current assembly process requirements of the wind measuring radar antenna components, the required installation depth and target preload force of the screws are precisely set. The controller 5 calculates the required control command according to the set parameters and drives the motor 2014 to rotate precisely. The motor 2014 drives the turntable 201. 1. Rotation drives the turntable 2013 and screwdriver 203 to rotate. The screwdriver 203 drives the screw held by the clamp 204 to rotate precisely. When the installation depth of the screw reaches the preset value and the system detects that the preload has reached the target value, the controller 5 sends a stop signal to immediately terminate the movement. This process can precisely control the installation depth and preload of the screw, avoid over-tightening or under-tightening, reduce manual intervention, improve the consistency and reliability of the assembly process, and ensure that the screw status of the key connection points of the wind measurement radar antenna accurately meets the design requirements.

[0040] Specifically, during operation, the operator inserts the screws used to fix the wind-measuring radar antenna components into the clamp 204, ensuring they are firmly clamped. The controller 5, based on the current assembly process requirements of the wind-measuring radar antenna components, precisely sets the required installation depth and target preload force for the screws. The controller 5 calculates the necessary control commands based on the set parameters, and drives the motor 2014 to rotate precisely. The motor 2014 drives the turntable 2011 to rotate, which in turn drives the turntable 2013 and the screwdriver 203 to rotate. The screwdriver 203 drives the screws clamped by the clamp 204 to rotate precisely. When the screw installation depth reaches the set value and the system detects that the preload force has reached the set target value, the controller 5 issues a stop signal, immediately stopping the movement. This precise control of the screw installation depth and preload force avoids over-tightening and under-tightening, reduces manual intervention, improves the consistency and reliability of the assembly process, and ensures that the screw status at key connection points of the wind-measuring radar antenna precisely meets design requirements.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 3 includes a connecting frame 305, which is equidistantly arranged on the front and rear sides of the bottom wall of the fixing plate 1. Multiple fixing rods 303 are equidistantly fixed to the top wall of the connecting frame 305, and the fixing rods 303 are connected to the fixing plate 1. Multiple limiting blocks 304 are equidistantly fixed to the front and rear sides of the outer wall of the connecting frame 305, and the limiting blocks 304 are slidably connected to the inner wall of the limiting groove 8. Mounting blocks 302 are fixedly connected to the left and right ends of the connecting frame 305. Engaging components 301 are installed on the left and right sides of the top wall of the connecting frame 305. Engaging components 301 include mounting plates 3013, which are fixedly connected to the front and rear sides of the top wall of the connecting frame 305. Fixing blocks 3012 are fixedly connected to the front and rear sides of the top wall of the mounting plate 3013. The upper middle part of the outer wall of the fixing blocks 3012... The rotating connection is provided with a buckle 3011, which is slidably connected to the inner wall of the groove on the left and right sides of the top wall of the fixed plate 1. The limiting groove 8 at the bottom of the fixed plate 1 is slid along the outer wall of the limiting block 304 until the groove on the left and right sides of the top wall of the fixed plate 1 is completely aligned with the fixed block 3012 and then the sliding stops. Subsequently, the operator needs to rotate the buckle 3011 so that the buckle 3011 is embedded in the groove on the top wall of the fixed plate 1, thereby realizing the stable connection of the fixed plate 1 on the fixed rod 303. This connection method significantly improves the rigidity of the structure, effectively prevents unnecessary vibration during the operation of the equipment, and avoids adverse effects on the scanning accuracy. In addition, this design can also effectively distribute the weight and vibration load of the equipment, further ensuring the stability and reliability of the equipment in various working environments.

[0042] Specifically, the limiting groove 8 at the bottom of the fixing plate 1 is slid along the outer wall of the limiting block 304. After the grooves on the left and right sides of the top wall of the fixing plate 1 are aligned with the fixing block 3012, the sliding stops. The buckle 3011 is rotated so that the buckle 3011 enters the groove on the top wall of the fixing plate 1, so that the fixing plate 1 is fixed on the fixing rod 303, forming a stable connection, improving the structural rigidity, preventing the equipment from shaking during operation, affecting the scanning accuracy, and distributing the weight and vibration load of the equipment.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the motor 2014 is equipped with a wire 4, the end of the wire 4 is equipped with a controller 5, the front left side of the controller 5 is equipped with a display screen 6, the right side of the display screen 6 is equipped with a button 7, and the button 7 is equidistantly installed on the front right side of the controller 5.

[0044] Specifically, the core function of controller 5 is to set and precisely control the screw installation depth and target preload parameters according to the specific requirements of the wind radar antenna assembly process. It receives the parameter values ​​set by the user and generates precise pulse signals to control the operating status of motor 2014, including but not limited to key parameters such as speed, direction, and number of steps. In addition, display screen 6 plays a crucial role. It is used to display key information such as the working status of the device, parameter settings, and fault prompts in real time, thereby supporting users to perform intuitive operation and monitoring. Button 7 provides users with an interface for inputting commands, allowing users to easily control the operation process of the device and ensure the smooth progress of the entire assembly process.

[0045] Working Principle: During operation, the operator first needs to insert the screws used to fix the wind measuring radar antenna components into the clamp 204, ensuring that the screws are firmly clamped. Then, through the controller 5, the operator needs to precisely set the required installation depth and target preload value for each screw according to the current assembly process requirements of the wind measuring radar antenna components. The controller 5 will calculate the required control commands based on these set parameters. Once the calculation is complete, the controller 5 will drive the motor 2014 to start rotating precisely. The motor 2014 drives the turntable 2011 to rotate, which in turn drives the turntable 2013 and the screwdriver. When screwdriver 203 rotates together with clamp 204, it drives the screw held by clamp 204 to rotate precisely. When the screw installation depth reaches the set value, or when the system detects that the preload has reached the set target value, the controller 5 will immediately issue a stop signal to stop all movement. This method of precisely controlling the screw installation depth and preload can effectively avoid the problems of over-tightening and insufficient preload, reduce manual intervention, and thus improve the consistency and reliability of the assembly process. In this way, it can ensure that the screw status of the key connection points of the wind measuring radar antenna accurately meets the design requirements, thus ensuring the accuracy and reliability of the equipment.

[0046] Slide the limiting groove 8 at the bottom of the fixing plate 1 along the outer wall of the limiting block 304 until the grooves on the left and right sides of the top wall of the fixing plate 1 are completely aligned with the fixing block 3012 and stop sliding. Next, the operator needs to rotate the buckle 3011 so that the buckle 3011 enters the groove on the top wall of the fixing plate 1. In this way, the fixing plate 1 is fixed on the fixing rod 303, forming a stable connection. This stable connection method can significantly improve the rigidity of the structure and prevent unnecessary vibration of the equipment during operation, thereby avoiding affecting the scanning accuracy. At the same time, this design can also effectively distribute the weight of the equipment and vibration load, further ensuring the stability and reliability of the equipment under various working conditions.
