[0044] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0045] The laser radar transceiver lens assembling device is used for assembling and adjusting the laser radar transceiver lens.

[0046] Reference Figure 1The laser radar transceiving lens assembly device 10 comprises a mounting member 110, a first adjusting assembly 120, a first clamping assembly 130, a second adjusting assembly 140, a second clamping assembly 150 and a third adjusting assembly 160. The mounting member 110 is used for mounting the transceiving module 20, and ensures the stability of the position of the transceiving module 20. The transceiving module 20 comprises a transmitting chip and a receiving chip. The first adjusting assembly 120 is connected with the mounting member 110 and adjusts the position of the transceiving module 20 by driving the mounting member 110. The first clamping assembly 130 can be used for clamping or releasing the transmitting lens 30. The second adjusting assembly 140 can be connected with the first clamping assembly 130 and adjusts the position of the transmitting lens 30 by driving the first clamping assembly 130. The second clamping assembly 150 can be used for clamping or releasing the receiving lens 40. The third adjusting assembly 160 can be connected with the second clamping assembly 150 and adjusts the position of the receiving lens 40 by driving the second clamping assembly 150. That is, the first adjusting assembly 120 can adjust the position of the transceiving module 20, the second adjusting assembly 140 can adjust the position of the transmitting lens 30, and the third adjusting assembly 160 can adjust the position of the receiving lens 40. The first adjusting assembly 120 adjusts the position of the transceiving module 20 to change the position between the transceiving module 20 and the light plate wall.

The third adjusting assembly 160 adjusts the position of the receiving lens 40 to align the optical axis of the receiving lens with the receiving chip in the transceiving module 20.

[0047] In the present application, since the transceiving module, the transmitting lens and the receiving lens are mounted on the mutually independent adjusting mechanisms, the movements of the components driven by the adjusting mechanisms are also mutually independent, so that the adjustment of the transmitting lens relative to the transceiving module and the adjustment of the receiving lens relative to the transceiving module do not interfere with each other.

[0048] In the present application, the first adjusting assembly 120 and the second adjusting assembly 140 are independently arranged from each other, and the first adjusting assembly 120 and the third adjusting assembly 160 are independently arranged from each other, so that the transceiving module, the transmitting lens and the receiving lens are also independent from each other. The advantages of such arrangement are that, first, the mounting of the transceiving module, the transmitting lens and the receiving lens on the corresponding adjusting assemblies is independent from each other, and second, the adjustment of the transmitting lens relative to the transceiving module by the adjusting assembly and the adjustment of the receiving lens relative to the transceiving module by the adjusting assembly are also independent from each other and do not interfere with each other, effectively improving the adjustment efficiency of the laser radar transceiving lens assembly device 10.

[0049] For example, continuing to refer to Figure 1The laser radar transceiving lens assembly device 10 further comprises an adjusting mechanism 170, and the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160 are all arranged on the adjusting mechanism 170. That is, the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160 are moved together under the driving of the adjusting mechanism 170. Especially suitable for the initial stage of the laser radar transceiving lens assembly process, when the position adjustment of the transceiving module 20, the transmitting lens 30 and the receiving lens 40 is needed, the transceiving module 20, the transmitting lens 30 and the receiving lens 40 can be simultaneously moved by controlling the adjusting mechanism 170, the adjusting process is more efficient, and the assembly efficiency of the laser radar transceiving lens is improved. The overall volume of the laser radar transceiving lens assembly device 10 can be smaller, and the cost is lower. In an embodiment not shown, the first adjusting assembly, the second adjusting assembly and the third adjusting assembly can be respectively correspondingly provided with an adjusting mechanism.

[0050] Exemplarily, continuing to refer to Figure 1 The adjusting mechanism 170 comprises a lifting adjusting assembly 1710, a rotating adjusting assembly 1720 and an adjusting mounting plate 1730, and the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160 can all be arranged on the adjusting mounting plate 1730 and moved with the adjusting mounting plate 1730. In an embodiment, the adjusting mounting plate 1730 can be arranged on the lifting adjusting assembly 1710, the rotating adjusting assembly 1720 can be connected with the lifting adjusting assembly 1710 and drive the lifting adjusting assembly 1710 and the adjusting mounting plate 1730 to rotate together in a predetermined plane, the lifting adjusting assembly 1710 drives the adjusting mounting plate 1730 to move in the z-axis direction, and the z-axis direction meets the vertical condition with the predetermined plane. When the rotating adjusting assembly 1720 is adjusted, the lifting adjusting assembly 1710, the first adjusting assembly 120, the second adjusting assembly 140, the third adjusting assembly 160 and the adjusting mounting plate 1730 are as a whole, and the rotating adjusting assembly 1720 drives the whole to rotate in the predetermined plane, that is, the angle adjustment of the transceiving module 20, the transmitting lens 30 and the receiving lens 40 in the predetermined plane is realized. When the lifting adjusting assembly is adjusted, the adjusting mounting plate 1730, the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160 are as a whole and moved under the driving of the lifting adjusting assembly 1710, that is, the position adjustment of the transceiving module 20, the transmitting lens 30 and the receiving lens 40 in the z-axis direction is realized.

[0051] Alternatively, in another embodiment, the adjusting mounting plate can be arranged on the rotating adjusting assembly, the lifting adjusting assembly is connected with the rotating adjusting assembly and drives the rotating adjusting assembly and the adjusting mounting plate to move together in the z-axis direction, the rotating adjusting assembly drives the adjusting mounting plate to rotate in a predetermined plane, and the predetermined plane satisfies the vertical condition with the z-axis direction. When the lifting adjusting assembly is adjusted, the rotating adjusting assembly, the first adjusting assembly, the second adjusting assembly, the third adjusting assembly and the adjusting mounting plate are as a whole, and the lifting adjusting assembly drives the whole to move in the z-axis direction, that is, the adjustment of the positions of the transceiving module, the transmitting lens and the receiving lens in the z-axis direction is realized. When the rotating adjusting assembly is adjusted, the adjusting mounting plate, the first adjusting assembly, the second adjusting assembly and the third adjusting assembly are as a whole and rotate in the predetermined plane under the driving of the rotating adjusting assembly, that is, the adjustment of the angles of the transceiving module, the transmitting lens and the receiving lens in the predetermined plane is realized.

[0052] The adjusting mechanism 170 arranged in this way can realize the adjustment of the angles of the transceiving module 20, the transmitting lens 30 and the receiving lens 40 in the predetermined plane and the adjustment of the positions of the transceiving module 20, the transmitting lens 30 and the receiving lens 40 in the z-axis direction, and the adjustment process is convenient and efficient. Exemplarily, the lifting adjusting assembly 1710 can be a scissor-type lifting device. The rotating adjusting assembly 1720 can be a rotary table type rotating device. The adjusting mounting plate 1730 can be fastened to the lifting adjusting assembly 1710 or the rotating adjusting assembly 1720, and the adjusting mounting plate 1730 can be provided with a matrix type mounting hole to be fastened to the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160, so that the first adjusting assembly 120, the second adjusting assembly 140 and the third adjusting assembly 160 form a more stable whole together and are lifted and rotated together. The second adjusting assembly 140 and the third adjusting assembly 160 are arranged together on the rotating adjusting assembly 1720, and can be fixed by gluing after the adjustment of the transmitting lens 30 and the receiving lens 40 is completed, which avoids the disassembly work of the transmitting lens 30 and the receiving lens 40 caused by repeated adjustment and improves the adjustment efficiency.

[0053] Exemplarily, in combination with the above description Figure 2 and Figure 3, the first adjusting assembly 120 can include a first lifting piece 1210 and a first multi-axis adjusting piece 1220, the first lifting piece 1210 is connected with the first multi-axis adjusting piece 1220 and drives the first multi-axis adjusting piece 1220 to move in the z-axis direction, that is, the transceiving module 20 moves under the drive of the first lifting piece 1210 and the first multi-axis adjusting piece 1220. The first multi-axis adjusting piece 1220 can be a four-axis adjusting structure, the first multi-axis adjusting piece 1220 includes a first moving piece 1221, a second moving piece 1222, a first rotating piece 1223 and a second rotating piece 1224, wherein the first moving piece 1221 is connected with the second moving piece 1222 and drives the second moving piece 1222 to move in the x-axis direction, the second moving piece 1222 is connected with the first rotating piece 1223 and drives the first rotating piece 1223 to move in the y-axis direction, the y-axis direction, the z-axis direction and the x-axis direction satisfy the perpendicular condition two by two, the first rotating piece 1223 is connected with the second rotating piece 1224 and drives the second rotating piece 1224 to rotate around the y-axis direction, and the second rotating piece 1224 is connected with the mounting piece 110 and drives the mounting piece 110 to rotate around the x-axis direction. It should be noted that in the embodiment shown in the figure, the z-axis direction is the vertical direction, and the x-axis direction and the y-axis direction are both horizontal directions and satisfy the perpendicular condition with each other, which all depend on the placement mode of the laser radar transceiving lens assembling device 10. When the laser radar transceiving lens assembling device 10 is placed in different directions, the three axial directions may change (for example, the z-axis direction may be a direction in the horizontal plane), but the relationship between the three axial directions is unchanged, that is, the perpendicular relationship between two is always guaranteed. In this way, under the cooperation of the first lifting piece 1210, the first moving piece 1221 and the second moving piece 1222, the movement of the transceiving module 20 in the x-axis direction, the y-axis direction and the z-axis direction can be realized. The rotation of the transceiving module 20 around the y-axis direction and around the x-axis direction is realized under the cooperation of the first rotating piece 1223 and the second rotating piece 1224. The setting of the first adjusting assembly 120 and the mounting piece 110 can adjust the horizontal relationship and the vertical relationship between the transceiving module 20 and the calibration environment, and the position of the transceiving module 20 remains unchanged after the adjustment is completed.

[0054] In this way, the first adjusting assembly 120 is set, which can meet the position and angle adjustment of the transceiving module 20 and has a simpler structure. For example, at least one of the first moving piece 1221, the second moving piece 1222, the first rotating piece 1223 and the second rotating piece 1224 is provided with an adjusting knob to facilitate the adjustment process. The first lifting piece 1210 can include a height adjusting knob and a locking device, and the user can adjust the position of the transceiving module 20 in the z-axis direction through the first lifting piece 1210 and lock it at a certain position to prevent accidental movement.

[0055] For example, in combination with the above Figure 2 ,Figure 6 and Figure 7 The mounting member 110 can include a connecting plate 1110 connected with the first adjusting assembly 120 and a mounting plate 1120 on which the transceiver module 20 is mounted. The connecting plate 1110 and the mounting plate 1120 can be connected in an L shape. The connecting plate 1110 and the mounting plate 1120 can be an integral piece. The connecting plate 1110 is provided with a first calibration hole 1111, and the mounting plate 1120 is provided with a second calibration hole 1121. The first calibration hole 1111 and the second calibration hole 1121 are spaced apart from each other and coincide in the z-axis direction. Exemplarily, the connecting plate 1110 is provided with a third calibration hole 1112 and a fourth calibration hole 1113 spaced apart from the third calibration hole 1112. The third calibration hole 1112 and the fourth calibration hole 1113 coincide in the x-axis direction. In the adjustment process, the first calibration hole 1111 and the second calibration hole 1121 are used to calibrate whether the mounting plate 1120 is perpendicular to the predetermined plane by light, that is, to judge whether the transceiver module 20 is perpendicular to the ground in actual work, thereby improving the calibration accuracy. The third calibration hole 1112 and the fourth calibration hole 1113 are used to calibrate the relationship between the mounting plate 1120 and the x-axis direction, that is, whether it is perpendicular to the x-axis direction, in actual work, that is, to judge whether the transceiver module 20 is perpendicular to the target surface, thereby improving the calibration accuracy. Specifically, the connecting plate 1110 and the mounting plate 1120 can be provided with protrusions, and the first calibration hole 1111, the second calibration hole 1121, the third calibration hole 1112 and the fourth calibration hole 1113 are respectively formed on the corresponding protrusions.

[0056] Exemplarily, in combination with reference to Figure 1 , Figure 2 , Figure 6 and Figure 7The mounting groove 1124 can be formed on the mounting plate 1120 for mounting the transceiver module 20. The first limiting surface 1125 perpendicular to the z-axis direction is arranged in the mounting groove 1124. The first fastener 1130 is connected to the mounting plate 1120, at least part of the structure of the first fastener 1130 extends into the mounting groove 1124 and is movable along the z-axis direction relative to the first limiting surface 1125. The transceiver module 20 is clamped between the first fastener 1130 and the first limiting surface 1125. The first fastener 1130 can be screwed to move along the z-axis direction. The first limiting surface 1125 abuts against the transceiver module 20, which limits the position of the transceiver module 20 along the z-axis direction. The first fastener 1130 can make the transceiver module 20 better abut against the first limiting surface 1125, and the transceiver module 20 is clamped between the first fastener 1130 and the first limiting surface 1125, so that the position of the transceiver module 20 along the z-axis direction is more stable. In addition, the cooperation between the first fastener 1130 and the first limiting surface 1125 can realize quick disassembly between the transceiver module 20 and the mounting plate 1120. The number of the first limiting surface 1125 can be arbitrarily set according to the use requirement. For example, the first limiting surface 1125 can be two and located on opposite sides of the mounting groove 1124. The transceiver module 20 abuts against both of the limiting surfaces.

[0057] For example, in combination with the above Figure 1 , Figure 6 and Figure 7 , the second limiting surface 1126 perpendicular to the y-axis direction can be arranged in the mounting groove 1124. The second fastener 1140 is connected to the mounting plate 1120, at least part of the structure of the second fastener 1140 extends into the mounting groove 1124 and is movable along the y-axis direction relative to the second limiting surface 1126. The transceiver module 20 is clamped between the second fastener 1140 and the second limiting surface 1126. The second fastener 1140 can be screwed to move along the y-axis direction. The second limiting surface 1126 abuts against the transceiver module 20, which limits the position of the transceiver module 20 along the y-axis direction. The second fastener 1140 can make the transceiver module 20 better abut against the second limiting surface 1126, and the transceiver module 20 is clamped between the second fastener 1140 and the second limiting surface 1126, so that the position of the transceiver module 20 along the y-axis direction is more stable.

[0058] For example, in combination with the above Figure 1 , Figure 6 and Figure 7A third limiting surface 1127 satisfying the perpendicular condition with the x-axis direction can be arranged in the mounting groove 1124, and the transceiver module 20 is attached to the third limiting surface 1127. The third limiting surface 1127 is the main positioning surface of the transceiver module 20, and the third limiting surface 1127 can be the groove bottom of the mounting groove 1124. The transceiver module 20 abuts against the third limiting surface 1127, so that the position of the transceiver module 20 in the x-axis direction is fixed. The first limiting surface 1125, the second limiting surface 1126 and the third limiting surface 1127 can form a positioning feature for the transceiver module 20, and the feature position corresponding to the positioning feature is determined as a certain value. Based on this value, the installation parts of the transceiver lens assembly devices of other models of laser radars can continue to be set based on this value, that is, the calibration environment can be reused, the workload of recalibrating the installation environment is reduced, and the installation efficiency is improved. Moreover, such a setting can reduce the variables generated by recalibrating the environment, and ensure the installation accuracy.

[0059] Exemplarily, in combination with reference to Figure 1 and Figure 5 , the first clamping assembly 130 can include a transmitting lens connecting piece 1330 and a transmitting lens clamp 1340.

[0074] In the adjustment process of the transceiver module 20, in order to adapt to small batch adjustment, an active adjustment scheme is usually used, that is, in the case of lighting the light source chip 201 of the transceiver module 20, the position of the lens (transmitting lens 30 or receiving lens 40) corresponding to the light source chip 201 is adjusted until the projection of the light spot of the light source chip 201 on the target surface 50 is completely coincided with the theoretical position. In the adjustment process, the following three points need to be ensured: 1. Ensure that the target surface 50 is completely parallel to the surface of the light source chip 201; 2. The distance between the target surface 50 and the surface of the light source chip 201 is completely accurate; 3. The central axis of the projection theoretical position on the target surface 50 is completely parallel to the central axis of the surface of the light source chip 201. Only when the three points are ensured at the same time, the projection of the light spot of the light source chip 201 on the target surface 50 can be completely coincided with the theoretical position. Otherwise, no matter how to adjust the position of the lens, the projection of the light spot of the light source chip 201 on the target surface 50 cannot be completely coincided with the theoretical position, resulting in that it is impossible to judge whether the lens is adjusted to the ideal position.

[0075] By reference Figure 1 , Figure 7 and Figure 8 , the distance between the total station 60 and the target surface 50 is L1, the mounting member 110 has a third calibration hole 1112 and a fourth calibration hole 1113, and the light source chip 201 is attached near the third calibration hole 1112. The thickness of the PCB board on which the light source chip 201 is located is L2, the distance between the third calibration hole 1112 and the fourth calibration hole 1113 is L3, the distance between the total station 60 and the fourth calibration hole 1113 is L4, and the distance between the light source chip 201 and the target surface 50 is L5. Figure 8 The horizontal laser is schematically shown by a dashed line, the distance between the side surface of the mounting member 110 for supporting the light source chip 201 and the through hole of the mounting member 110 for passing the horizontal laser is D1, and the size of the chip is D2.

[0076] The adjustment process of the transceiver module 20 can be as follows:

[0077] Level the total station 60, and the total station 60 is the only reference for subsequent adjustment;

[0078] Adjust the position of the target surface 50 so that the target surface 50 is perpendicular to the horizontal laser line of the total station 60, and the distance between the target surface 50 and the total station 60 is L1;

[0079] The light source chip 201 is installed on the mounting piece 110, the mounting piece 110 and the first adjusting assembly 120 are located between the total station 60 and the target surface 50, the position of the mounting piece 110 is adjusted, the horizontal laser of the total station 60 passes through the third calibration hole 1112 and the fourth calibration hole 1113, the diameters of the third calibration hole 1112 and the fourth calibration hole 1113 are all smaller than the diameter of the horizontal laser spot of the total station 60 at the position, since the inner walls of the third calibration hole 1112 and the fourth calibration hole 1113 are smooth metal materials, if the laser of the total station 60 passes through the horizontal hole position of the clamp but is not coaxial, the light spot on the target surface 50 will have obvious halo deviating to one side, the position of the mounting piece 110 is finely adjusted, so that the halo basically disappears or becomes a concentric circle, at this time, the third calibration hole 1112 and the fourth calibration hole 1113 are coaxial with the horizontal laser of the total station 60, at this time, it can be ensured that the target surface 50 and the surface of the light source chip 201 are completely parallel;

[0080] The fourth calibration hole 1113 is shielded by using a thin and opaque adhesive tape, the distance L4 between the fourth calibration hole 1113 and the total station 60 is adjusted, so that L5=L1-(L4+L3+L2), at this time, it is ensured that the distance between the target surface 50 and the surface of the light source chip 201 is completely accurate;

[0081] According to D1 and D2 and the known size of the light source chip 201, the intersection of the central axis of the light source chip 201 and the target surface 50 can be marked, and the intersection is the distortion zero point during subsequent lens assembly and adjustment;

[0082] According to the lens distortion parameters, the total station 60 is used to mark the remaining light spot projection mark points on the target surface 50, when the assembly and adjustment are completed and the mark points are coincided with the actual light spot projection, it can be ensured that the central axis of the projection theoretical position on the target surface 50 is completely parallel to the central axis of the surface of the light source chip 201, at this time, the three points mentioned above are met, and the assembly and adjustment of the transceiver module 20 can be completed.
