Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lens assembly, in particular to a lens and rotating mirror bonding device and bonding method. BACKGROUND

[0002] Now, lenses are applied to various products, such as notebook computers, mobile phones, tablet computers, laser radars, etc., but the structures and assembly methods of lenses are different. For example, the principle of laser radar detecting whether there is an object in front is generally that the light emitted by the laser is reflected by the high-speed rotating rotating mirror and then shines on the measured object. The light is reflected to the receiver by the measured object and the rotating mirror. If there is no object, the light will not be reflected back, thereby determining whether there is an object in front. The rotating mirror includes a polyhedral mirror frame and a lens bonded to the surface of the mirror frame. When the lens is bonded to the surface of the mirror frame, the lens AA bonding mechanism is used to adjust the position of the lens relative to the mirror frame to ensure that the angle and height of the lens bonded to the surface of the mirror frame are accurate in each direction.

[0003] The bonding of the lens and the mirror frame is usually performed by using UV glue. In the bonding process, the tightness, size matching, and curing of the UV glue between the lens and the mirror frame are strictly required, otherwise the performance of the assembled lens will be affected. Now, there are many devices for bonding lenses and mirror frames, for example, the scheme of the multi-channel laser radar lens AA device disclosed in Chinese patent application CN116251715A. After the reflecting lens b is grabbed by the AA mechanical arm 22, the laser radar body a on the adjusting base 21 is first glued, then the reflecting lens b is pre-AA by the adjusting mechanism 221. There is a certain height difference between the pre-AA and the actual AA. The reflecting lens b does not contact the glue during pre-AA, then the adjusting mechanism 221 drives the reflecting lens b to be vertically pressed against the laser radar body a to realize AA, which can effectively avoid the repeated extrusion of the glue during AA and make the glue not uniform. However, the existing lens and rotating mirror bonding device ignores the problem caused by the characteristics of the UV glue, that is, the UV glue is a non-Newtonian fluid. When the reflecting lens is vertically pressed against the laser radar body, the UV glue will be subjected to a large impact force and become very hard, which will hinder the movement of the lens towards the bonding surface of the mirror frame, resulting in that the lens cannot be accurately bonded to the specified distance from the mirror frame. In severe cases, this hindering force can even damage the lens, reducing the quality of the lens and affecting the performance of the lens. SUMMARY

[0004] In view of the above, the present application aims to provide a lens and rotating lens fitting device, which sets a collimator on the fitting device, calibrates the dimensions between the lens and the frame, sets a buffer fine adjustment cylinder combination component, absorbs the impact force between the lens and the frame during fitting, and reduces the acting force between the lens and the frame at the fitting moment through the buffer fine adjustment cylinder, thereby solving the problem that the lens cannot be accurately fitted to the specified distance from the frame, and the hindering force even damages the lens, reduces the lens quality, and affects the performance of the lens.

DETAILED DESCRIPTION

[0063] In order to make the above objectives, features and advantages of the present application more obvious and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0064] The descriptions involving “first”, “second”, “upper”, “lower” and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features indicated or the number of the technical features indicated. Therefore, the features defined with “first”, “second”, “upper”, “lower” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the realization of a person skilled in the art, and when the technical solutions of the embodiments can be combined, they are all within the protection scope required by the present application.

[0065] The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0066] As Figure 1 and Figure 2As shown, a lens and a rotating mirror fitting device, comprising: a lens fitting device 100 and a frame fixing device 200. The lens fitting device 100 comprises: a fitting mechanism 110 and a detection mechanism 120, the fitting mechanism 110 comprises: a fixing part 111, a curing lamp 112, a state adjusting assembly and a buffer assembly. The fixing part 111 is provided with a fixing surface, and the lens is detachably fixed on the fixing surface. A through hole is provided on the fixing part 111, which penetrates the fixing part 111 from the fixing surface. The light irradiation direction of the curing lamp 112 is parallel to the fixing surface. The state adjusting assembly is used to adjust the movement of the fixing part 111 and the curing lamp 112 along the X-axis and the Z-axis, and the rotation of the fixing part 111 and the curing lamp 112 around the Y-axis and the Z-axis. The buffer assembly is used to absorb the impact energy of the fixing part 111 moving along the X-axis. The detection mechanism 120 is used to detect the state of the fixing part 111. The frame fixing device 200 comprises: a frame fixed on the end of the fixing shaft 210, and the fixing shaft 210 can move and rotate along the Y-axis.

[0067] During the fitting operation, the lens is fixed on the fixing surface of the fixing part 111. Preferably, a through hole is provided on the fixing part 111 from the fixing surface, which penetrates the fixing part 111. The through hole is communicated with the air extraction device. During the fixing of the lens, air extraction is performed to adsorb the lens on the fixing surface. After the lens is fixed, the state of the fixing part 111 is detected by the detection mechanism 120 to ensure that the position, angle and the like of the lens meet the fitting requirements. If the fitting requirements are not met, the state of the fixing part 111 is adjusted by the state adjusting assembly. After the state of the lens is adjusted, the frame with the UV glue coated on the surface is installed on the fixing shaft 210 and moved along the Y-axis direction. The fixing part 111 is moved along the X-axis direction, so that the lens gradually approaches the frame. The installation of the frame and the fixing shaft 210 can adopt a hard fitting structure such as interference fit, screw locking and thread locking, so as to ensure that the frame will not be displaced after being assembled on the fixing shaft 210. When the lens and the frame are fitted, the impact force between the lens and the frame is absorbed by the buffer assembly until the buffer assembly absorbs all the impact energy. Then, a small amount of gas is continuously filled into the buffer assembly, so that the lens continues to slowly move towards the frame. The acting force between the lens and the frame is not enough to increase the hardness of the UV glue, so as to ensure that the lens is accurately fitted on the frame and the distance between the lens and the frame meets the design requirements. After the lens and the frame are fitted, the UV glue is cured by the curing lamp 112. Preferably, the curing lamp 112 adopts a UV lamp.

[0068] Through the fitting device with the above structure, the impact energy is effectively absorbed by the buffer assembly, and the impact force between the lens and the frame is consumed, so that the lens is fitted on the frame with small force, which will not cause the UV glue to harden and affect the fitting accuracy of the lens and the frame. It is ensured that the lens is accurately fitted on the frame at a specified distance, which avoids damaging the lens, improves the quality of the lens, and meets the performance of the lens.

[0069] Further, as shown in Figure 3 The state adjusting assembly includes an X-axis driving assembly 116, a Z-axis driving assembly 115, a rotating table 114 and an angle adjusting assembly 113. The X-axis driving assembly 116 drives the fixing member 111 and the curing lamp 112 to move along the X-axis. The Z-axis driving assembly 115 includes a first member and a second member. The first member is movably connected with the X-axis driving assembly 116 along the X-axis direction. The second member is movably connected with the first member along the Z-axis direction. The movement of the second member relative to the first member along the Z-axis direction drives the fixing member 111 and the curing lamp 112 to move along the Z-axis direction. The rotating table 114 is connected with the second member. The rotating table 114 drives the fixing member 111 and the curing lamp 112 to rotate around the Z-axis. The angle adjusting assembly 113 is fixed on the rotating table 114. The angle adjusting assembly 113 drives the fixing member 111 and the curing lamp 112 to rotate around the Y-axis.

[0070] The X-axis driving assembly 116 is the base assembly of the lens fitting device 100, which carries the fitting mechanism 110 and drives the fitting mechanism 110 to move along the X-axis. The X-axis driving assembly 116 can be any existing transmission mechanism. For example, as an embodiment, a motor drives a screw rod, the bottom of the fitting mechanism 110 is connected to a sliding block, and the sliding block is provided with a screw hole matched with the screw rod. The fitting mechanism 110 and the detection mechanism 120 are driven to move along the X-axis by a screw nut transmission mechanism. After the lens is fixed on the fixing member 111, the height of the lens is adjusted in the height direction by the Z-axis driving assembly 115. As an embodiment, the Z-axis driving assembly 115 includes a fixed block 1152 (i.e., the first assembly) and a sliding block 1151 (i.e., the second assembly), the sliding block 1151 is stacked above the fixed block 1152, the opposite surfaces of the fixed block 1152 and the sliding block 1151 are matching inclined surfaces, the sliding block 1151 is driven to move along the X-axis by a motor, and the fitting mechanism 110 is driven to move up and down. The rotating table 114 rotates around the Z-axis to adjust the rotation angle of the fixing member 111 around the Z-axis. The angle adjustment assembly 113 rotates around the Y-axis to adjust the pitch angle of the fitting mechanism 110. The angle adjustment assembly 113 can use existing products. As an embodiment, the angle adjustment assembly 113 includes a concave member and a convex member, the opposite surface of the concave member is an inner concave spherical surface, and the opposite surface of the convex member is a convex spherical surface matched with the inner concave spherical surface. The pitch angle of the fitting mechanism 110 is adjusted by rotating the convex member around the Y-axis. The fitting mechanism 110 is moved along the X-axis and the Z-axis and rotated around the Z-axis and the Y-axis by the above-mentioned structure of the state adjustment assembly.

[0071] Further, the buffer assembly includes a bearing plate, the fixing member 111 and the curing lamp 112 are fixed on the bearing plate. The buffer fine adjustment cylinder assembly includes a cylinder and a piston, the cylinder is connected with a gas supply device, and the piston is connected with the bearing plate.

[0072] The fixing member 111 and the curing lamp 112 are driven to move along the X-axis by the buffer fine adjustment cylinder assembly. The reaction force relative to the impact force between the lens and the frame is adjusted by changing the gas pressure of the input gas, the impact force is absorbed, and the lens can be slowly fitted to the frame, and the fitting defects caused by the non-Newtonian fluid characteristics of the UV glue are solved. Specifically, under the action of the X-axis driving assembly 116, the lens moves towards the frame, at the moment when the lens contacts the frame, the gas pressure of the input gas in the cylinder is not enough to resist the impact force, and the piston slowly retracts to absorb the impact force. After the impact force is completely absorbed, the gas pressure of the input gas in the cylinder is increased, so that the lens slowly continues to move towards the frame until the distance between the lens and the frame meets the design requirements.

[0073] Further, as shown in Figure 4 The detection mechanism 120 includes a collimator 121 and a detection adjustment assembly. The collimator 121 is used to detect whether the light direction is coaxial or parallel with the via axis. The detection adjustment assembly carries the collimator 121, and adjusts the offset angle of the collimator 121 through the detection adjustment assembly.

[0074] The collimator 121 can adopt existing products. The offset angle of the collimator 121 is adjusted through the detection adjustment assembly, so that the light direction emitted by the collimator 121 is coaxial or parallel with the via axis. Similarly, the rotation angle of the collimator 121 around the Z axis and the Y axis is adjusted.

[0075] Specifically, the detection adjustment assembly includes a detection Y-axis adjuster 122 and a detection Z-axis turntable 123. The detection Y-axis adjuster 122 carries the collimator 121 and adjusts the rotation angle of the collimator 121 around the Y axis. The detection Z-axis turntable 123 carries the detection Y-axis adjuster 122 and the collimator 121, and adjusts the rotation angle of the collimator 121 around the Z axis.

[0076] The detection Z-axis turntable 123 adjusts the rotation angle of the collimator 121 around the Z axis, which can adopt the same structure as the rotary table 114 and the angle adjustment assembly 113. The detection Y-axis adjuster 122 adjusts the rotation angle of the collimator 121 around the Y axis, which is the same as the angle adjustment assembly 113.

[0077] Further, as shown in Figure 5 The frame fixing device 200 further includes a Y-axis driving assembly 240, a driver 230, and a sensor 220. The Y-axis driving assembly 240 drives the fixed shaft 210 to move along the Y-axis direction. The driver 230 is movably arranged on the Y-axis driving assembly 240 along the Y-axis direction, and the fixed shaft 210 is arranged on the driver 230 and is driven to rotate around the Y axis by the driver 230. The fixed shaft 210 is driven to rotate by the driver 230, so that the fitting surface of the frame is parallel to the lens. The fixed shaft 210 is driven to move along the Y-axis direction by the Y-axis driving assembly 240, so that the frame is moved to a position corresponding to the lens. The fixed part 111 is driven to move along the first direction of the X axis toward the frame by the X-axis driving assembly 116, so that the lens is fitted on the frame. The sensor 220 detects whether the frame is installed on the fixed shaft 210.

[0078] The Y-axis driving combination component 240 and the X-axis driving combination component 116 can adopt the same structure. The driver 230 is movably connected with the Y-axis driving combination component 240. The driver 230 drives the fixed shaft 210 to rotate. The sensor 220 is arranged around the fixed frame to detect whether the frame is mounted on the fixed shaft 210, and if not, send information to the control device and issue an alarm.

[0079] Further, as shown in the drawings, the lens and the rotating mirror fitting device further comprises an adjusting device 300 and a base 400. The adjusting device 300 comprises a rotating shaft 310 and a limiting combination component. The rotating shaft 310 is connected with the first direction end of the X-axis driving combination component 116. The limiting combination component is connected with the other end of the X-axis driving combination component 116 relative to the rotating shaft 310, and limits the rotation angle of the fixed part 111 through the limiting combination component, and fixes the lens fitting device 100. The lens fitting device 100, the frame fixing device 200 and the adjusting device 300 are fixed on the base 400. Figure 6

[0080] According to the temple angle (the included angle between the lens fitting surface and the axis of the frame), the lens fitting device 100 is driven to rotate through the rotating shaft 310, so as to roughly adjust the angle of the lens rotating around the Z-axis. When the lens fitting device 100 rotates to the position corresponding to the temple angle, the position of the other end of the X-axis driving combination component 116 relative to the rotating shaft 310 can be limited through the limiting combination component. This design can meet the assembly of rotating mirrors with different temple angles, and the operation of adjusting the lens fitting device 100 is very flexible and convenient.

[0081] Specifically, the limiting combination component comprises a track 340, a mounting plate 320 and an angle fine adjuster 350. The track 340 is arc-shaped, and the track 340 is fixed on the base 400 with the axis of the rotating shaft 310 as the center. The lens fitting device 100 is fixed on the mounting plate 320, and a sliding structure matched with the track 340 is arranged on the surface of the mounting plate 320 relative to the base 400. A push block 330 is arranged on the mounting plate 320, and the push block 330 protrudes from the edge of the mounting plate 320 close to the limiting combination component. The angle fine adjuster 350 is fixed on the base 400, and two micrometers 351 are oppositely arranged on the angle fine adjuster 350.

[0082] ​The lens fitting device 100 is carried by the mounting plate 320, the mounting plate 320 rotates around the rotating shaft 310, the other end of the mounting plate 320 is limited by the arc-shaped track 340, and the track 340 and the rotating shaft 310 prevent the mounting plate 320 from moving during rotation. The lower surface of the mounting plate 320 is provided with a sliding structure matched with the track 340. On the mounting plate 320, a plurality of arc-shaped screw holes are arranged near the angle fine adjuster 350, and the arcs formed by the screw holes also have the rotating shaft 310 as the center. The angle fine adjuster 350 is provided with bolt through holes matched with the screw holes, the bolt through holes are preferably arc-shaped elongated holes, and at least two bolt through holes are arranged. After the mounting plate 320 is rotated to a suitable position, the angle fine adjuster 350 is fixed at the corresponding position, the push block 330 is clamped from both sides by the two opposite micrometers 351, and the angle of the lens fitting device 100 is finely adjusted by the fine adjuster micrometer 351.

[0083] As an embodiment, the sliding structure is a sliding block, and the edge part opposite to the track 340 of the sliding block is arc-shaped and matched with the track 340.

[0084] In the embodiment, the sliding block contacts the track 340 from the inner side of the track 340. The sliding structure can also adopt other forms, for example, a roller, or an arc-shaped groove matched with the track 340 arranged at the bottom of the mounting plate 320, or a U-shaped sliding block buckled on the track 340, a U-shaped groove arranged at the bottom of the sliding block, the U-shaped groove being arc-shaped and matched with the track 340, or other forms, as long as the sliding structure can be matched with the track 340 to slide along the track 340.

[0085] A lens and rotating mirror fitting method, characterized in that the fitting method is performed by the lens and rotating mirror fitting device according to any one of the above.

[0086] S100, a standard lens is fixed on the fixing part, the light emitting direction of the collimator is adjusted, and the standard lens is removed after the light reflected by the lens received by the collimator coincides with the incident light;

[0087] When the light reflected by the lens received by the collimator coincides with the incident light, it indicates that the light emitting direction of the collimator is coaxial or parallel with the axis of the through hole. The collimator is used to judge whether the lens on the vacuum suction block is tilted or rotated, if the lens is tilted or rotated, the light emitted by the collimator cannot be received after being reflected by the lens, and the lens on the vacuum suction block needs to be finely adjusted by the rotating table and the angle adjusting table on the lifting slide. If there is no tilt or rotation, the reflected light can be received, so that the collimator completes accurate positioning of the lens during fitting.

[0088] S200, coaxially fix a standard rotating mirror at the end of the fixed shaft, adjust the angle of the lens fitting device so that the collimator receives the light reflected by the standard rotating mirror;

[0089] By rotating the shaft, the mounting plate, the detection mechanism and the fitting mechanism are driven to rotate around the standard rotating mirror until the collimator can receive the light reflected by the standard rotating mirror.

[0090] S300, fine-tune the lens fitting device through the angle fine-tuner so that the light emitted by the collimator coincides with the light reflected by the rotating mirror;

[0091] By fine-tuning the mounting plate through the angle fine-tuner, the light emitted by the collimator coincides with the light reflected by the rotating mirror, indicating that the light emitted by the collimator is perpendicular to the lens on the rotating mirror, thereby completing the positioning work before work.

[0092] S400, coaxially install the frame with UV glue on the fitting surface to the end of the rotating main shaft, and drive the frame to rotate to the fitting angle;

[0093] Since the frame is hard assembled with the rotating main shaft, the installation position of the frame is the standard position by default.

[0094] S500, fix the lens on the fixed surface of the fixing member, detect whether the lens has pitch deviation and rotation deviation through the collimator, if there is deviation, fine-tune the lens through the rotating table and the angle adjustment assembly until the light emitted by the collimator coincides with the light reflected by the lens;

[0095] S600, drive the fitting mechanism to move towards the fitting surface of the frame through the X-axis drive assembly, inflate the buffer fine-tuning cylinder assembly, and the inflation pressure is less than the reaction force received by the lens during fitting, so that the piston is compressed to move into the cylinder, acting as an energy-absorbing spring, absorbing part of the impact energy, the UV glue will not harden due to excessive impact force, and the lens can continue to move towards the fitting surface;

[0096] S700, continue to drive the fitting mechanism to move towards the fitting surface of the frame through the X-axis drive assembly until the pressure in the buffer fine-tuning cylinder assembly balances with the reaction force received by the lens, and the lens cannot continue to move towards the fitting surface;

[0097] At this time, the distance between the lens and the frame is greater than the design requirement.

[0098] S800, continue to inflate the cylinder of the buffer fine-tuning cylinder assembly, and the pressure of the inflated gas needs to ensure that the lens cannot generate excessive force on the UV glue, so as to avoid affecting the fitting effect of the lens. Drive the lens to continue to move towards the fitting surface until the distance between the lens and the frame reaches the design requirement.
