[0056] It should be understood that although the terms first, second, third, etc. can be used in the embodiments of the present application to describe, these should not be limited to these terms. These terms are only used to distinguish. For example, without departing from the scope of the embodiments of the present application, the first can also be called the second, and similarly, the second can also be called the first.

[0057] It should also be noted that the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the goods or devices including a series of elements not only include those elements, but also include other elements not explicitly listed, or include elements inherent to such goods or devices. Without more limitation, the element defined by the sentence "including one" does not exclude the presence of other identical elements in the goods or devices including the element.

[0058] The following describes the optional embodiments of the present application in detail with reference to the accompanying drawings.

[0059] According to one of the specific embodiments of the present application, as Figure 1As shown, the present application provides a lens assembly jig for accurately installing a lens 7 to be installed on a laser ranging radar LDS, wherein the laser ranging radar LDS is used for obstacle detection of a robot, which can be a vacuum suction robot, a mopping / brushing / sweeping robot, etc. In order to enable the laser ranging radar LDS to accurately perform obstacle detection, the optical device needs to be accurately positioned during the assembly of the laser ranging radar LDS, in particular, the assembly of the optical system therein. Therefore, the present lens assembly jig is used to accurately assemble the lens to the laser transceiver module 5 of the laser ranging radar LDS.

[0060] Specifically, the lens assembly jig comprises a bottom plate 6 having horizontal upper and lower surfaces, providing a basic platform for the lens assembly jig assembly, and a plurality of mounting holes of different sizes on the bottom plate 6, which can be provided with threads, and the mounting holes can be blind holes or through holes, which are not limited. Each element of the lens assembly jig is directly or indirectly fixed to the bottom plate 6, such as Figure 1 As shown.

[0061] The lens assembly jig further comprises a bracket 1 embedded in the bottom plate 6, specifically, the bracket 1 is embedded in the recess formed in the bottom plate 6, and the bracket 1 has a gap with the four walls and the bottom surface of the recess, which is convenient for adjusting the xyz direction in the subsequent lens position adjustment process. The bracket 1 comprises a support vertical plate 14 and a support horizontal plate 15, the support horizontal plate 15 is fixed to the top end of the support vertical plate 14 by bolts, and a plurality of mounting holes of different sizes are also provided on the support vertical plate 14 and the support horizontal plate 15, which can be blind holes or through holes. The bracket 1 further comprises a slide rail 11 extending from the recess of the bottom plate 6 to the support horizontal plate 15 in the vertical direction, which can be fixed to the support horizontal plate 15 after passing through the support horizontal plate 15. The slide rail 11 is usually two parallel cylindrical slide rails, which is convenient for the sliding block to slide up and down and ensures the stability of the sliding. The number and shape of the slide rail are not limited, for example, the slide rail can also be a polygonal prism or a cuboid.

[0062] Optionally, the bracket 1 further comprises a resilient member 13, such as a spring, which is sleeved on the slide rail 11 and is arranged between the slide rail 11 and the slide hole. A stop portion for fixing the spring can be arranged in the slide hole. When the sliding block 12 moves upward, the spring is compressed by the stop portion. When the sliding block 12 moves downward, the spring releases the elastic force and further provides an elastic force downward to ensure that the lens is tightly installed to the laser transceiver module 5 of the laser ranging radar LDS.

[0063] Optionally, the slider 12 is provided with a clamping member in the transverse direction, which cooperates with a locking member on the supporting vertical plate 14 to achieve locking of the sliding movement. The structure of the clamping member and the locking member is not limited, for example, it can be a concave-convex clamping, or an elastic clamping. When the slider 12 is slid upward to a predetermined position, the clamping member and the locking member are temporarily fixed by cooperation. When the lens to be installed is installed in the lens mounting seat 2, the clamping member and the locking member are unlocked by external force. The clamping member and the locking member can enable the lens mounting seat 2 to be stably positioned at a predetermined height of the support 1, freeing the hands to install the lens, and ensuring that the lens can be accurately positioned on the lens mounting seat 2.

[0064] As shown in Figure 2 , the lens assembly jig further includes a lens mounting seat 2, which is used to accurately transport the lens to be installed to the installation position, for example, the lens barrel of the laser transceiver module 5 of the laser detection radar LDS. To this end, the lens mounting seat 2 includes a lens positioning base 21 and a lens gland 22. The lens positioning base 21 is used to position the lens to be installed. The lens positioning base 21 can have an L-shaped structure, as shown in Figure 3 , one end of the L-shaped structure includes a plurality of mounting holes of different sizes, which are fixedly connected to the transverse mounting holes of the slider 12, so that the lens positioning base 21 can move along the longitudinal direction with the slider 12. The other end of the lens positioning base 21 includes a lens adapter 211 for positioning the lens to be installed. The lens adapter 211 further includes a first notch 2111 and a first lug 2112. The first notch 2111 is adapted to the body of the lens to be installed, for example, the first notch 2111 has a circular structure or a square structure with a diameter greater than that of the body of the lens to be installed. The shape is not limited. In order to ensure the smooth detachment of the lens to be installed after being installed in the specified position, the opening angle of the first notch 2111 is set to 30-90 degrees. The first lug 2112 is symmetrically arranged on both sides of the first notch 2111 and is adapted to the bait part of the lens to be installed. For example, the first lug 2112 has a recess structure for accommodating the bait part of the lens to be installed, so that when the bait part of the lens to be installed is placed in the recess structure, the body of the lens to be installed has little room for movement, thereby ensuring accurate positioning of the lens to be installed.

[0065] As another embodiment, the recess structure has a regular protrusion pattern, which can have a protruding strip shape, a dot shape, a petal shape, etc., to cooperate with the bait part structure to achieve stable positioning. For example, the corresponding position of the bait part is provided with a corresponding recess pattern. When the bait part is placed in the recess structure, the recess pattern of the bait part matches the protrusion pattern of the recess structure, thereby increasing the stable combination of the lens to be installed and the lens adapter.

[0066] As shown in Figure 4As shown, the lens cap 22 is disposed above the lens positioning base 21. When the lens is installed on the lens positioning base 21, the lens cap 22 fastens to the lens positioning base 21 and presses the lens to be installed. Optionally, the lens cap 22 includes a second notch 221 and a second lug 222, wherein the second notch 221 corresponds to the position of the first notch 2111 and the size of the second notch 221 is equivalent to that of the first notch 2111. When the lens cap 22 is fixed to the lens positioning base 21, the lens can be completely exposed from the second notch 221 and the first notch 2111 to ensure the subsequent optical path is unobstructed; the shape of the second notch 221 also matches the shape of the first notch 2111 to ensure the optical path is unobstructed. The second lug 222 is symmetrically disposed on both sides of the second notch 221 and is used to cooperate with the first lug 2112 to press the bait part. As an optional implementation, the second lug 222 has a matching snap-fit ​​pattern at the contact position with the first lug 2112. When the lens to be installed is assembled onto the first lug 2112, the resulting recessed structure is filled by the snap-fit ​​pattern of the second lug 222, ultimately achieving a smooth fit between the first lug 2112, the second lug 222, and the bait portion in between. This allows the lens to be installed stably on the lens positioning base. Furthermore, the lens cap 22 also has multiple mounting holes of varying sizes, which are used to securely mount the lens to the lens positioning base 21.

[0067] Among them, such as Figure 5 As shown, the lens 7 to be installed includes a body 71 and a bait section 72. The body 71 refers to the lens that is installed in the laser transceiver module 5 of the laser detection radar LDS. The bait section 72 is a connecting structure pre-set on both symmetrical sides of the body 71 to fix the lens 7 to be installed. It has an irregular shape, such as square, round, annular, strip, petal, etc., and the corresponding shape can match the shape of the recessed structure of the first lug 2112. The bait section 72 can be made of resin material. After the body 71 is installed in the laser transceiver module 5 of the laser detection radar LDS, the bait section 72 is detached from the body 71. The bait section 72 can be reused or is a disposable material. By setting the bait section 72 on the body 71, the body 71, which is originally small and difficult to operate, has the performance of flexible assembly. By placing the body 71 in the assembly state with the bait section 72, the accuracy of the body 71 assembly is increased. Moreover, since the bait section has the property of being easy to detach, it does not affect the use of the lens after assembly.

[0068] As an optional implementation method, such as Figure 2As shown, the lens mounting seat 2 further comprises a hand-held part 23 connected to the side of the lens positioning base 21, for moving the lens mounting seat 2 up and down under the action of external force. The hand-held part 23 is provided with an anti-skid structure, for example, the anti-skid structure is provided as a concave-convex dot matrix structure or a stripe structure. When it is needed to assemble the lens to be installed to the laser transceiver module 5, the lens positioning base 21 is lifted up by the hand-held part 23, and the lens positioning base 21 slides upwards along the slide rail. After sliding to the predetermined position, the locking structure on the sliding block is locked with the bracket. At this time, the lens mounting seat 2 can be fixed, the lens to be installed is placed into the lens adapting part 211, and the lens to be installed is fixed after adding the lens gland 22. After the laser transceiver module 5 is placed into the laser transceiver module base 4, the lens mounting seat 2 is moved downwards by the hand-held part 23 under the cooperation of the spring, until the lens body is assembled to the laser transceiver module 5 of the laser detection radar LDS, as shown in Figure 6

[0069] As an optional embodiment, when it is needed to assemble the lens to be installed, the lens positioning base 21 is lifted up by the hand-held part 23, and the lens positioning base 21 slides upwards along the slide rail. After sliding to the predetermined position, one hand holds the hand-held part 23, and the other hand places the lens to be installed into the lens adapting part 211, and fixes the lens to be installed after adding the lens gland 22. Then, the lens mounting seat 2 is moved downwards by the hand-held part 23 under the cooperation of the spring, until the lens body is assembled to the laser transceiver module 5.

[0070] As an optional embodiment, when it is needed to assemble the lens to be installed, the lens to be installed can be placed into the lens adapting part 211 before the hand-held part 23 is lifted up, and the lens to be installed is fixed after adding the lens gland 22. Then, the lens positioning base 21 with the lens to be installed is lifted up by the hand-held part 23, and the laser transceiver module 5 is placed into the laser transceiver module base 4. Then, the lens mounting seat 2 is moved downwards by the hand-held part 23 under the cooperation of the spring, until the lens body is assembled to the laser transceiver module 5.

[0071] As an optional embodiment, as shown in Figure 7 As an optional embodiment, as shown in Figure 7 ​The adjustment mode of the three-axis sliding table 3 is manually rotating the knobs in the x, y and z directions, the knobs have a preset screw pitch, and the distance of the support 1 in the x, y and z directions can be finely adjusted by finely adjusting the knobs in the x, y and z directions, so that the distance of the to-be-installed lens in the x, y and z directions can be adjusted, and the to-be-installed lens can be more accurately aligned with the optical center of the laser transceiver module 5 of the laser detection radar LDS.

[0072] As an optional embodiment, as shown in Figure 8 As shown, the lens assembly jig further comprises a laser transceiver module base 4, wherein the laser transceiver module base 4 is fixed to the bottom plate 6 and located below the lens mounting seat 2, the laser transceiver module base 4 has a hollow structure and is fixed to the bottom plate 6 through screws around the periphery; the laser transceiver module 5 is installed in the hollow structure of the laser transceiver module base 4 and used for accommodating the body of the to-be-installed lens in the lens mounting seat 2 and assembling the body of the to-be-installed lens to the laser transceiver module. The laser transceiver module 5 can be a transceiver module of a laser detection radar LDS, which generally comprises a laser light source, a control circuit and a laser emission module and a laser receiving module, wherein the laser emission module and the laser receiving module have independent barrels, and each independent barrel is provided with an optical lens, which is generally a convex lens. Since the conventional manual installation method has the defects of instability and inaccuracy, the jig as described above can be used for installation.

[0073] As an optional embodiment, the laser transceiver module base 4 further comprises a power-on probe 41 arranged on the side of the laser transceiver module base 4. The power-on probe 41 can be a retractable probe. When the body of the to-be-installed lens is assembled into the barrel of the laser transceiver module 4, the laser transceiver module 5 moves downward under the action of the lens mounting seat 2, so that the power-on probe 41 with a small gap and the connection terminal of the circuit board 51 at the edge of the laser transceiver module 5 are in contact. The power-on probe 41 is in conduction with the circuit board 51 at the edge of the laser transceiver module 5. Through the control of the electric control box and the control panel, the laser transceiver module 5 can simulate the emission and reception of laser, and the position of the to-be-installed lens is finely adjusted through the three-axis sliding table 3 until accurate installation is achieved.

[0074] The lens assembly jig provided by the present disclosure can improve the accuracy of lens assembly, and through the further calibration of the CCD camera, the lens can be more accurately assembled to the to-be-installed position.

[0075] According to another specific embodiment of the present disclosure, asFigure 9 As shown, the present application provides a lens assembly device, comprising a CCD camera 200 and a lens assembly jig 100 as any of the above, wherein the CCD camera 200 is used to calibrate the position of the lens to be installed. The CCD camera 200 can receive the light emitted by the laser transceiver module 5 and form a light spot image, and can simulate the position of the returned light on the image. The CCD camera 200 transmits the image information to the display device, and the operator can further adjust the attitude of the lens to be installed according to the displayed light spot position, such as adjusting the position in x, y, z direction, until the light spot position is accurately displayed in the preset position.

[0076] Specifically, the lens assembly device includes an electric control box 400, which includes a controller, a circuit board, a power supply and other devices, for providing power and control functions for the lens assembly device, and the control method is not described here. The electric control box 400 is provided with a control panel 600, which includes switches, UV curing and other operation buttons, for controlling the assembly device during the lens assembly process. The electric control box 400 is placed on the upper surface of the lens assembly jig 100, wherein the bottom plate 6 of the lens assembly jig 100 is fixedly installed on the upper surface of the electric control box 400. A UV lamp curing assembly 500 is provided beside the lens assembly jig 100, which is used to cure the position of the lens to be installed. The CCD camera 200 and the fill light 300 are installed on the upper surface of the electric control box 400 through the support rod, and the fill light 300 is used to observe when the ambient light is insufficient during the test. The height and direction of the CCD camera 200 and the fill light 300 can be controlled through the controls on the support rod, and their positions can be adjusted as needed to achieve precise imaging or obtain the corresponding fill light as needed. In addition, the fill light 300 can be provided with a power adjustment button to control the brightness of the fill light as needed.

[0077] When the lens to be installed is roughly installed through the lens assembly jig 100 to the laser transceiver module of the laser detection radar LDS, the power-on probe 41 is in conduction with the circuit board at the edge of the laser transceiver module 5. At this time, the laser transceiver module 5 can be controlled by the electric control box and the control panel to emit detection laser, and the detection laser enters the CCD camera 200. The position of the lens is judged by the optical position of the CCD camera 200. When the position is deviated, the position of the lens to be installed is fine-tuned through the three-axis sliding table 3 until it is accurately installed. Then glue is dispensed around the lens installation position, and the UV lamp curing assembly is controlled to irradiate to realize lens curing, and finally the precise assembly of the lens is completed.

[0078] The lens assembly device provided by the present disclosure has simple structure and convenient operation. The bait part is arranged on the lens. The lens to be installed is first fixed to the positioning base, and then positioned at the installation position. The three-axis sliding table is used for calibration. The CCD camera is used for further calibration. The lens is more accurately assembled to the installation position. Finally, the lens is glued to the periphery of the installation position, and the UV lamp curing assembly is used for irradiation to cure the lens. Finally, the precise assembly of the lens is completed.

[0079] According to the specific embodiment of the present disclosure, in another aspect, the present disclosure provides a lens assembly method, comprising the lens assembly jig according to any one of the above, and the method specifically comprises the following steps: Figure 10

[0080] Step S1001: The lens positioning base is lifted upward, so that the lens positioning base slides upward along the slide rail to a predetermined position.

[0081] Step S1003: The laser transceiver module is placed in the laser transceiver module base.

[0082] Step S1005: The lens positioning base is moved downward, so that the lens to be installed is installed on the laser transceiver module.

[0083] In some embodiments, before or after the lens positioning base is lifted upward, so that the lens positioning base slides upward along the slide rail to a predetermined position, the lens to be installed is placed in the lens fitting part of the lens positioning base, and the lens to be installed is positioned by the lens gland.
