Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser tracking technology, in particular to a laser tracking control device. BACKGROUND

[0002] With the rapid development of electronic information technology, the processing and manufacturing field of electronic products, electronic parts and electronic computers and their accessories is moving towards high precision, high efficiency and intelligentization. In modern industrial production, especially in the precise assembly of electronic products, the positioning and processing of micro parts, and the precise assembly of internal components of electronic computers, the precision and stability of the processing equipment are highly required. Laser tracking technology, as a non-contact, high-precision measurement and control method, has great application potential in the field of electronic manufacturing due to its advantages of fast measurement speed, high precision and strong anti-interference ability.

[0003] Currently, when adjusting the elevation angle of the laser emitting mechanism, the single side of the laser emitting mechanism is usually driven, and the double sides of the laser emitting mechanism cannot be synchronously driven, resulting in unbalanced stress on the two sides of the laser emitting mechanism when adjusting the elevation angle, affecting the stability of the elevation angle adjustment. CONTENT OF THE INVENTION

[0004] In view of the shortcomings of the prior art, the present application provides a laser tracking control device, which has the advantages of synchronously driving the two sides of the laser emitting mechanism when adjusting the elevation angle of the laser emitting mechanism, avoiding the phenomenon of movement lag and unbalanced stress on the two sides of the laser emitting mechanism, improving the stability of the elevation angle adjustment of the laser emitting mechanism, etc. The problems of the prior art, such as the single side of the laser emitting mechanism being driven when adjusting the elevation angle of the laser emitting mechanism, the double sides of the laser emitting mechanism being unable to be synchronously driven, the unbalanced stress on the two sides of the laser emitting mechanism when adjusting the elevation angle, and the stability of the elevation angle adjustment being affected, are solved.

[0005] To achieve the goal of synchronously driving both sides of the laser emitting mechanism when adjusting its elevation angle, avoiding motion lag and force imbalance on both sides, and improving the stability of the laser emitting mechanism during elevation angle adjustment, this application provides the following technical solution: A laser tracking control device includes a laser emitting mechanism, which is located inside an elevation angle adjustment housing, which is located above a horizontal adjustment housing. Two support shafts are provided on both sides of the laser emitting mechanism. Two first gears are provided at the ends of the two support shafts away from the laser emitting mechanism. The two first gears mesh with two second gears. The two second gears are located on the motor shafts at both ends of a dual-axis servo motor. The two first gears are located on both sides of the laser emitting mechanism, and the positions of the two second gears correspond to those of the two first gears.

[0006] The elevation adjustment housing is located at the top of the rotating shaft. A turbine is provided on the outer surface of the middle part of the rotating shaft. The turbine meshes with a worm gear. One end of the worm gear is located on one end of the motor shaft of the horizontal adjustment servo motor. The bottom of the horizontal adjustment servo motor is fixed to the bottom of the inner wall of the horizontal adjustment housing via a fixing block. The end of the worm gear away from the horizontal adjustment servo motor is rotatably located at the bottom of the inner wall of the horizontal adjustment housing via a support plate.

[0007] The above scheme utilizes a dual-axis servo motor to drive two second gears to rotate synchronously. These second gears, in turn, drive two first gears to rotate synchronously. Consequently, each first gear in the chain drives both sides of the laser emitting mechanism synchronously via two support shafts. This achieves synchronous driving of both sides of the laser emitting mechanism when adjusting its elevation angle, preventing motion lag and force imbalance on both sides and improving the stability of the laser emitting mechanism during elevation angle adjustment.

[0008] Furthermore, both the first gear and the second gear are located inside the elevation adjustment housing.

[0009] By placing the first and second gears inside the elevation adjustment housing, the gear transmission mechanism can be effectively protected from external environmental interference, extending the service life of the gears. At the same time, it ensures the stability and accuracy of gear meshing and avoids transmission errors or malfunctions caused by external factors.

[0010] Furthermore, the outer surface of the middle part of the support shaft is rotatably disposed within the inner wall of the inner side of the elevation adjustment housing.

[0011] The above solution allows the laser emitting mechanism to be supported by a rotating support shaft located inside the inner wall of the elevation angle adjustment housing, thereby improving the stability of the laser emitting mechanism during rotation.

[0012] Furthermore, the dual-axis servo motor is mounted on the bottom wall of the inner wall of the elevation adjustment housing via a support frame.

[0013] By using the above solution, the dual-axis servo motor is fixed to the bottom wall of the elevation adjustment housing using a support frame, which ensures that the dual-axis servo motor remains stable during operation and avoids displacement or loosening caused by vibration or impact.

[0014] Furthermore, a first support groove is provided on the side of the first gear away from the support shaft, and a first support ring is rotatably provided on the inner wall of one side of the first support groove. The first support ring is provided on the inner side wall of the elevation adjustment housing.

[0015] The above scheme allows the first gear to be supported by the first support groove and the first support ring, and the stability of the first gear during rotation can be improved by the rotational cooperation between the first support groove and the first support ring.

[0016] Furthermore, a second support groove is provided on the side of the second gear away from the dual-axis servo motor, and a second support ring is rotatably provided on the inner wall of one side of the second support groove. The second support ring is provided on the inner side wall of the elevation adjustment housing.

[0017] The above scheme allows the second gear to be supported by the second support groove and the second support ring. The rotational engagement of the second support groove and the second support ring can improve the stability of the second gear during rotation and improve the meshing accuracy between the second gear and the first gear.

[0018] Furthermore, a third support groove is provided on the top of the horizontal adjustment housing, and a third support ring is rotatably provided on one side inner wall of the third support groove. The third support ring is located at the bottom of the elevation adjustment housing.

[0019] Through the above scheme, the cooperation between the third support groove and the third support ring can support and guide the horizontal rotation of the elevation angle adjustment shell, ensuring that it remains stable and without shaking during the horizontal adjustment process.

[0020] Furthermore, one end of the rotating shaft is rotatably disposed at the bottom of the inner wall of the horizontal adjustment housing, the other end of the rotating shaft extends to the top of the horizontal adjustment housing, and the outer surface of one side of the middle part of the rotating shaft is rotatably disposed within the top inner wall of the horizontal adjustment housing.

[0021] The above solution allows for the fixation of the rotating shaft's position by engaging one end of the rotating shaft, the outer surface of the middle section, with the horizontal adjustment housing, thereby improving the stability of the rotating shaft during rotation.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This laser tracking control device uses a dual-axis servo motor to drive two second gears to rotate synchronously. These second gears simultaneously drive two first gears to rotate synchronously, which in turn drives both sides of the laser emitting mechanism synchronously via two support shafts. This achieves synchronous driving of both sides of the laser emitting mechanism when adjusting its elevation angle, avoiding motion lag and force imbalance on both sides of the laser emitting mechanism, and improving the stability of the laser emitting mechanism during elevation angle adjustment.

[0035] Please see Figure 3 , Figure 4 and Figure 5 The first gear 5 and the second gear 6 are both located inside the elevation adjustment housing 2. By setting the first gear 5 and the second gear 6 inside the elevation adjustment housing 2, the gear transmission mechanism can be effectively protected from interference from the external environment, the service life of the gears can be extended, and the stability and accuracy of gear meshing can be ensured, avoiding transmission errors or failures caused by external factors.

[0036] Please see Figure 3 , Figure 4 and Figure 5 The outer surface of the middle part of the support shaft 4 is rotatably set inside the inner wall of the elevation angle adjustment housing 2. By rotatably setting the support shaft 4 inside the inner wall of the elevation angle adjustment housing 2, the laser emitting mechanism 1 can be supported, thereby improving the stability of the laser emitting mechanism 1 when it rotates.

[0037] Please see Figure 3 , Figure 4 and Figure 5 The dual-axis servo motor 7 is mounted on the bottom wall of the inner wall of the elevation adjustment housing 2 via a support frame. By fixing the dual-axis servo motor 7 to the bottom wall of the elevation adjustment housing 2 via the support frame, it can be ensured that the dual-axis servo motor 7 remains stable during operation and avoid displacement or loosening caused by vibration or impact.

[0038] Please see Figure 3 , Figure 4 and Figure 5A first support groove 12 is provided on the side of the first gear 5 away from the support shaft 4. A first support ring 13 is rotatably provided on the inner wall of one side of the first support groove 12.

[0040] Please see Figure 3 , Figure 4 and Figure 5 The top of the horizontal adjustment housing 3 is provided with a third support groove 16, and a third support ring 17 is rotatably provided on one side of the inner wall of the third support groove 16. The third support ring 17 is located at the bottom of the elevation adjustment housing 2.

[0041] Please see Figure 3 , Figure 4 and Figure 5 Figure 3 Figure 4 Figure 5 One end of the rotating shaft 8 is rotatably disposed at the bottom of the inner wall of the horizontal adjustment housing 3, and the other end of the rotating shaft 8 extends to the top of the horizontal adjustment housing 3. The outer surface of one side of the middle part of the rotating shaft 8 is rotatably disposed in the top inner wall of the horizontal adjustment housing 3. The rotation position of the rotating shaft 8 can be fixed by the rotational cooperation between one end of the rotating shaft 8, the outer surface of one side of the middle part, and the horizontal adjustment housing 3, thereby improving the stability of the rotating shaft 8 when rotating.

[0042] In this embodiment, a laser tracking control device operates via a dual-axis servo motor 7, which drives two second gears 6 to rotate synchronously. These two second gears 6 simultaneously drive two first gears 5 to rotate synchronously. This, in turn, causes each first gear 5 to synchronously drive both sides of the laser emitting mechanism 1 via two support shafts 4. This achieves synchronous driving of both sides of the laser emitting mechanism 1 when adjusting its elevation angle, preventing motion lag and force imbalance on both sides of the laser emitting mechanism 1, and improving the stability of the laser emitting mechanism 1 during elevation angle adjustment.

[0043] The working principle of the above embodiment is as follows: The dual-axis servo motor 7 operates, driving the two second gears 6 to rotate synchronously. When the second gears 6 rotate, the second support groove 14 and the second support ring 15 will slide into contact, causing the two second gears 6 to simultaneously drive the two first gears 5 to rotate synchronously. When the first gears 5 rotate, the first support groove 12 and the first support ring 13 will slide into contact. When the two first gears 5 rotate, they will synchronously drive both sides of the laser emitting mechanism 1 through the two support shafts 4, so that the laser emitting mechanism 1 can be adjusted in elevation under balanced force on both sides. The horizontal adjustment servo motor 11 operates, driving the worm gear 10 to rotate, which in turn drives the turbine 9. The turbine 9 drives the rotating shaft 8 to rotate, which in turn drives the elevation adjustment housing 2 to rotate, thereby adjusting the laser emitting mechanism 1 horizontally.
