[0044] The embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0045] This disclosure provides an assembly apparatus for assembling the housing and window of a lidar. The assembly apparatus includes a bracket, a first clamp, and a second clamp. The bracket includes a motion guide mechanism and a base. The first clamp is detachably mounted on the motion guide mechanism and can secure the lidar housing. The second clamp is detachably mounted on the base and can secure the lidar window. The first and second clamps can be mounted on the bracket and can also be removed from the bracket. When the first and second clamps are mounted on the bracket, the bracket allows the first and second clamps to move closer together. The housing, fixed to the first clamp, and the window, fixed to the second clamp, fit together to assemble the housing and window. The bracket can bring the first and second clamps closer together to a closed position. In the closed position, the first and second clamps can fit the housing and window together.

[0046] In some embodiments, the assembly device can assemble the housing and window of the lidar. A first clamp and a second clamp are used to fix the housing and window respectively, and are detachably mounted on a bracket. The bracket brings the first and second clamps close together, causing the housing and window to fit together. When the first and second clamps are close together, the housing and window remain fitted, assembling them together. The first and second clamps can be removed from the bracket, freeing them from occupancy and improving assembly efficiency.

[0047] For example, the processes of using the first clamp to fix the outer casing and the second clamp to fix the window can be performed simultaneously at different workstations, which helps improve assembly efficiency. After fixing the outer casing to the first clamp and the window to the second clamp, the first and second clamps are placed on a support, and the support moves the first and second clamps closer together. After the outer casing and the window are in contact, the first and second clamps are removed from the support, freeing them from occupying the support.

[0048] In some embodiments, adhesive can be applied to the housing or window. When the bracket aligns the housing and window, they can be bonded together using adhesive. After molding, the first and second clamps are removed from the bracket, and the adhesive can be cured in other locations or using other devices or equipment. Molding means that the first and second clamps are brought close together to a closed position. During the adhesive curing process, additional first and second clamps can be installed on the bracket for assembling other lidar housings and windows. This improves the utilization rate of the assembly equipment and increases the assembly efficiency of the lidar.

[0049] Figure 1 The structure of an exemplary assembly apparatus consistent with some embodiments of the present disclosure is shown. Reference Figure 1 The assembly device 100 is used to assemble the housing 110 and the viewing window 112 of the lidar. The assembly device 100 includes a bracket 102, a first clamp 104 and a second clamp 106.

[0050] See Figure 1 In some embodiments of this disclosure, the bracket 102 includes a motion guide mechanism 122 and a base 124. A first clamp 104 is detachably mounted on the motion guide mechanism 122. A second clamp 106 is detachably mounted on the base 124.

[0051] The first clamp 104 can secure the housing 110. For example, the motion guide mechanism 122 includes a mounting positioning member, and the first clamp 104 can cooperate with the mounting positioning member to be mounted on or removed from the motion guide mechanism 122. The first clamp 104 may include a clamping member or a fastener. The clamping member or fastener can secure the housing 110 to the first clamp 104. The housing 110 moves with the first clamp 104.

[0052] The second clamp 106 can secure the viewing window 112. For example, the base 124 includes a mounting positioning element, and the second clamp 106 can cooperate with the mounting positioning element to be mounted on or removed from the base 124. The second clamp 106 may include a clamping element or a fastener. The clamping element or fastener can secure the viewing window 112 to the second clamp 106. The viewing window 112 moves with the second clamp 106.

[0053] In some embodiments, the first clamp 104 holds the housing 110 in a fixed position. The second clamp 106 holds the window 112 in a fixed position. This helps to improve the accuracy of the assembly of the housing 110 and the window 112.

[0054] The bracket 102 can bring the first clamp 104 and the second clamp 106 closer together, so that the housing 110 fixed by the first clamp 104 and the viewing window 112 fixed by the second clamp 106 fit together. In some embodiments, the motion guide mechanism 122 can drive the first clamp 104 to move. For example, the motion guide mechanism 122 driving the first clamp 104 to move includes driving the first clamp 104 to rotate or translate at least one of them.

[0055] refer to Figure 1 In some embodiments, the motion guide mechanism 122 includes a pivot and can drive the first clamp 104 to rotate about the pivot so that the mounting position of the window of the housing 110 corresponds to that of the window 112. The housing 110 is generally as follows: Figure 1 The orientation shown. The plane where the window is mounted in the housing 110 ( Figure 1 The plane that is roughly vertical and the plane where window 112 is located ( Figure 1 The plane is roughly horizontal and roughly vertical. The motion guide mechanism 122 drives the first clamp 104 to rotate around the pivot, so that the window mounting position of the housing 110 is rotated to face the window 112. For example, the first clamp 104 rotates 90° so that the plane where the window mounting position of the housing 110 is located is parallel to the plane where the window 112 is located.

[0056] In some embodiments, the motion guide mechanism 122 can drive the first clamp 104 to translate, so that the first clamp 104 moves closer to or away from the base 124. For example, after the first clamp 104 is mounted on the motion guide mechanism 122, the window mounting position of the housing 110 is approximately directly above the window 112. The motion guide mechanism 122 can drive the first clamp 104 to move vertically, so that the first clamp 104 moves closer to or away from the base 124.

[0057] In some embodiments, the motion guide mechanism 122 can drive the first clamp 104 to rotate and translate. For example, the first clamp 104 is horizontally disposed on the motion guide mechanism 122. The motion guide mechanism 122 drives the first clamp 104 to rotate, and the viewing window of the housing 110 is mounted approximately above the viewing window 112. The motion guide mechanism 122 also drives the first clamp 104 to move downward in the vertical direction, so that the first clamp 104 moves closer to the second clamp 106, so that the housing 110 and the viewing window 112 are in contact.

[0058] In some embodiments, the base 124 may be fixedly mounted on the worktable. The control motion guide mechanism 122 drives the first clamp 104 to translate along a straight line or rotate about an axis, so that the first clamp 104 and the second clamp 106 move closer to each other.

[0059] In some embodiments, the housing 110 and the window 112 can be fixedly connected by snap-fit, adhesive, or heat fusion. After the bracket 102 moves the first clamp 104 and the second clamp 106 closer together until the housing 110 and the window 112 are attached, the housing 110 and the window 112 can be fixed together by pressing and snap-fit, adding fasteners, applying pre-applied adhesive, injecting glue, or heat fusion. For example, adhesive can be applied to the housing 110 or the window 112. After the housing 110 and the window 112 are attached, the adhesive on the housing 110 adheres to the window 112, or the adhesive on the window 112 adheres to the housing 110, thus fixing the housing 110 and the window 112 together.

[0060] In some embodiments, the assembly device 100 further includes at least one floating element. The floating element is disposed on the base 124 or the second clamp 106, or simultaneously on the base 124 and the second clamp 106. The floating element allows the second clamp 106 to translate, tilt, or rotate relative to the base 124, which facilitates the fitting of the viewing window 112 and the housing 110 after the first clamp 104 and the second clamp 106 are closed.

[0061] See Figure 2In some embodiments, a floating element 114 is disposed on a base 124. A second clamp 106 is connected to the base 124 via the floating element 114. The floating element 114 can provide the second clamp 106 with a degree of freedom of movement relative to the base 124. For example, the floating element 114 includes a helical spring. The second clamp 106 is connected to the base 124 via the helical spring. During the mold closing process of the first clamp 104 and the second clamp 106, the housing 110 and the viewing window 112 abut against each other. The helical spring undergoes elastic deformation after being compressed, and the helical spring is compressed or tilted. The second clamp 106 translates or tilts relative to the base 124 so that the viewing window 112 is fully fitted at the viewing window mounting position in the housing 110. In some embodiments, the floating element 114 can improve the accuracy of the assembly of the housing 110 and the viewing window 112, and reduce the requirements for the machining accuracy of the housing 110 and the viewing window 112, which is beneficial to reducing the machining difficulty and machining cost.

[0062] In some embodiments, the assembly device 100 includes a plurality of floating members 114, for example Figure 2 The device includes two floating elements 114. Multiple floating elements 114 are located at different positions on the base 124 and the second clamp 106. The multiple floating elements 114 cooperate to allow the second clamp 106 to rotate at a certain angle relative to the base 124. For example, each floating element 114 includes a helical spring. Different helical springs have different compression amounts or different tilt directions when compressed. The second clamp 106 can rotate at a certain angle relative to the base 124.

[0063] In some embodiments, the assembly device 100 further includes a locking member 108. The locking member 108 can lock the first clamp 104 and the second clamp 106 together after the mold is closed. (See reference) Figure 3 The mold closing refers to the first clamp 104 and the second clamp 106 approaching each other to a closed position. In the closed position, the first clamp 104 and the second clamp 106 can bring the housing 110 and the window 112 into contact. In the closed position, the housing 110 and the window 112 are in an assembly posture. For example, the bracket 102 drives the first clamp 104 and the second clamp 106 to move relative to each other. When the first clamp 104 and the second clamp 106 move to the point where the housing 110 and the window 112 are in contact, the locking member 108 can lock the relative positional relationship of the first clamp 104 and the second clamp 106, so that the housing 110 and the window 112 remain in contact.

[0064] The housing 110 is secured using a first clamp 104, and the viewing window 112 is secured using a second clamp 106. When the first clamp 104 and the second clamp 106 are closed, a locking member 108 is used to lock the first clamp 104 and the second clamp 106 in place. The assembly apparatus 100 of this disclosure improves the assembly accuracy of the housing 110 and the viewing window 112 and reduces the assembly difficulty.

[0065] In some embodiments, after the first clamp 104 and the second clamp 106 are molded together, the first clamp 104 and the second clamp 106 are locked by the locking member 108. The first clamp 104 and the second clamp 106 can be removed from the bracket 102 while locked. The locking member 108 keeps the housing 110 and the window 112 in contact, which facilitates the installation of the housing 110 and the window 112. For example, while waiting for the adhesive to cure. The first clamp 104 and the second clamp 106 do not occupy space in the bracket 102 after removal. The bracket 102 can be used to install another set of the first clamp 104 and the second clamp 106, which helps to improve work efficiency.

[0066] In some embodiments, the locking member 108 may be disposed on the first clamp 104 and the second clamp 106. The locking member 108 locks when the first clamp 104 and the second clamp 106 are closed. Alternatively, in some embodiments, the locking member 108 may be disposed independently of the first clamp 104 and the second clamp 106. After the first clamp 104 and the second clamp 106 are closed, the locking member 108 locks the first clamp 104 and the second clamp 106.

[0067] In some embodiments, the locking member 108 includes a locking lever 182 and a mating member 184. The locking lever 182 is disposed on one of the first clamp 104 and the second clamp 106. The mating member 184 is disposed on the other of the first clamp 104 and the second clamp 106. For example Figure 4A and Figure 4B As shown, the locking lever 182 is mounted on the first clamp 104. Figure 5 As shown, the mating part 184 is disposed on the second clamp 106.

[0068] The mating part 184 can engage with the locking lever 182 to lock the first clamp 104 and the second clamp 106 together. For example, as the first clamp 104 and the second clamp 106 approach each other, the mating part 184 and the locking lever 182 approach each other until the mating part 184 and the locking lever 182 engage with each other.

[0069] In some embodiments, the assembly device 100 includes two locking members 108. (See reference) Figure 4A and Figure 4BTwo locking levers 182 are disposed on both sides of the first clamp 104. The locking member 108 includes two mating members 184. The two mating members 184 are disposed on both sides of the second clamp 106. In some embodiments, the assembly device 100 includes three or more locking members 108 distributed at different positions of the first clamp 104 and the second clamp 106, which helps to improve the stability of maintaining the locked state when the first clamp 104 and the second clamp 106 are closed.

[0070] In some embodiments, reference Figure 4A , Figure 4B and Figure 6A The locking lever 182 is roughly cylindrical in shape. (Reference) Figure 6A The locking lever 182 includes a groove 192. The locking lever 182 also includes a first end 194, a second end 196, and a mounting portion 198. The mounting portion 198 is used to fix the locking lever 182 onto the first clamp 104. Exemplarily, the mounting portion 198 is embedded within the first clamp 104. The first end 194 and the second end 196 protrude from the first clamp 104. For example, the first end 194 and the second end 196 protrude from the side of the first clamp 104 facing the second clamp 106 when the mold is closed. The groove 192 is disposed between the first end 194 and the second end 196. In a plane perpendicular to the direction from the first end 194 to the second end 196, the cross-sectional dimension of the groove 192 is smaller than the cross-sectional dimensions of the first end 194 and the second end 196. Exemplarily, in a plane perpendicular to the direction from the first end 194 to the second end 196, the cross-sectional shape of the groove 192, the first end 194, and the second end 196 is circular. The center of the cross-section of the groove 192 coincides with the center of the cross-sections of the first end 194 and the second end 196. The diameter of the cross-section of the groove 192 is smaller than the diameter of the cross-sections of the first end 194 and the second end 196.

[0071] refer to Figure 5 and Figure 6B The mating part 184 is disposed on the side of the second clamp 106 facing the first clamp 104 when the mold is closed, or the mating part 184 is disposed on the side of the second clamp 106. The position of the mating part 184 corresponds to the position of the locking rod 182. When the first clamp 104 and the second clamp 106 are closed, the mating part 184 is engaged in the groove 192 of the locking rod 182, which can lock the relative position of the first clamp 104 and the second clamp 106, keeping the outer shell 110 and the viewing window 112 in contact.

[0072] In some embodiments, the locking lever 182 includes a guide surface 186. The guide surface 186 can be used to guide the locking lever 182 and the mating member 184 to lock. For example, the guide surface 186 is an inclined surface or a curved surface. As the first clamp 104 and the second clamp 106 approach each other, the locking lever 182 and the mating member 184 are pressed against each other. The guide surface 186 guides the mating member 184 to engage within the groove 192 of the locking lever 182.

[0073] For example, refer to Figure 6A The second end 196 of the locking lever 182 has a guide surface 186 between its end face and the groove 192. The guide surface 186 is inclined. As the first clamp 104 and the second clamp 106 approach each other, the mating part 184 abuts against the guide surface 186. Then, as the first clamp 104 and the second clamp 106 continue to approach each other, the locking lever 182 and the mating part 184 move relative to each other. For example, the second end 196 of the locking lever 182 can move towards the second clamp 106. Finally, the mating part 184 can engage within the groove 192 of the locking lever 182.

[0074] In some embodiments, the mating member 184 can extend and retract. For example, the mating member 184 is disposed on the second clamp 106. The mating member 184 can extend or retract relative to the second clamp 106. For example, Figure 6B The structure of an exemplary mating member 184 consistent with some embodiments of the present disclosure is shown. Reference Figure 5 The second clamp 106 has a mounting groove 168 on its side. A portion of the mating member 184 is located within the mounting groove 168, and another portion extends from the mounting groove 168 to protrude from the side of the second clamp 106. See also... Figure 5 and Figure 6B The control part 188 of the mating part 184 can extend relative to the second clamp 106. The control part 188 of the mating part 184 can also retract relative to the second clamp 106 to fully enter the interior of the second clamp 106, or to enter the interior of the second clamp 106 in a larger part.

[0075] In some embodiments, the mating member 184 further includes a clamping portion 190. The clamping portion 190 has an arcuate wall that mates with a groove 192 of the locking lever 182. The control portion 188 and the clamping portion 190 are rotatable about a pivot. Exemplarily, the control portion 188 and the clamping portion 190 are integrally formed.

[0076] When the control portion 188 of the mating member 184 is in the extended position, the mating member 184 can engage in the groove 192 of the locking lever 182. The first clamp 104 and the second clamp 106 are locked. When the control portion 188 of the mating member 184 retracts into the second clamp 106, the clamping portion 190 rotates away from the locking lever 182. The mating member 184 disengages from the groove 192 of the locking lever 182. The first clamp 104 and the second clamp 106 are unlocked.

[0077] In some embodiments, when the first clamp 104 and the second clamp 106 are not closed, the mating member 184 can be in the extended position. For example, the mating member 184 includes an elastic structure. Under the action of the elastic structure, the mating member 184 remains in the extended position. When the first clamp 104 and the second clamp 106 approach each other, under the action of the guide surface 186, or by manual operation by the operator, the elastic structure is compressed, and the mating member 184 retracts, allowing the first clamp 104 and the locking rod 182 to continue moving towards the second clamp 106. When the position of the arcuate wall of the mating member 184 corresponds to the position of the groove 192 of the locking rod 182, the mating member 184 extends under the action of the elastic structure. The mating member 184 engages within the groove 192 of the locking rod 182 and remains locked.

[0078] In some embodiments, the mating member 184 can be manually controlled to switch between an extended position and a retracted position. When the first clamp 104 and the second clamp 106 approach each other, the mating member 184 is placed in the retracted position to reduce the resistance of the mating member 184 to the locking lever 182. After the first clamp 104 and the second clamp 106 close, the mating member 184 is placed in the extended position so that the mating member 184 engages in the groove 192 of the locking lever 182. The first clamp 104 and the second clamp 106 are then locked.

[0079] In some embodiments, the locking member 108 can lock the first clamp 104 and the second clamp 106 through other structures. For example, the locking member 108 includes a bolt or a retaining pin. The first clamp 104 and the second clamp 106 are provided with threaded holes or through holes. After the first clamp 104 and the second clamp 106 are closed, the bolt or retaining pin can be fixed at the position of the threaded hole or through hole to lock the first clamp 104 and the second clamp 106.

[0080] In some embodiments, reference Figure 4A and Figure 4B The first clamp 104 has a first positioning part 142. (Reference) Figure 5The second fixture 106 has a second positioning part 162. After the first fixture 104 and the second fixture 106 are closed, the first positioning part 142 and the second positioning part 162 engage. For example, the first positioning part 142 and the second positioning part 162 can be engaged by snap-fit, plug-in, nesting, meshing, or other methods. The engagement of the first positioning part 142 and the second positioning part 162 can improve the accuracy of the first fixture 104 and the second fixture 106 during mold closing, and improve the assembly accuracy of the housing 110 and the window 112.

[0081] In some embodiments, reference Figure 4A and Figure 4B The first positioning part 142 may include a protruding structure. For example, the protruding structure is fixed to the first clamp 104 and protrudes towards the second clamp 106. The second positioning part 162 may include blind holes, through holes, slots, or other structures that cooperate with the protruding structure. (See reference) Figure 5 The second positioning part 162 includes a blind hole. When the first clamp 104 and the second clamp 106 are closed, the protruding structure is embedded in the blind hole. In some embodiments, by means of the complementary shapes of the first positioning part 142 and the second positioning part 162, the first clamp 104 and the second clamp 106 can be guided to close, thereby improving the closing accuracy of the first clamp 104 and the second clamp 106.

[0082] In some embodiments, the first positioning portion 142 may include a blind hole. The second positioning portion 162 may include a protruding structure. Alternatively, in some embodiments, the first clamp 104 includes a plurality of first positioning portions 142. The second clamp 106 includes the same number of second positioning portions 162 as the number of first positioning portions 142. Exemplarily, the first positioning portions 142 and the second positioning portions 162 correspond one-to-one.

[0083] In some embodiments, the first positioning part 142 and the second positioning part 162 have a finished surface at the engagement position, which can further improve the mold closing accuracy of the first clamp 104 and the second clamp 106.

[0084] In some embodiments, at least one of the first positioning portion 142 and the second positioning portion 162 has a guide surface. For example, the end of the protrusion near the blind hole has an inclined surface or a curved surface. The opening of the blind hole is open outward. As the first clamp 104 and the second clamp 106 approach each other, the guide surface can reduce the difficulty of the first positioning portion 142 and the second positioning portion 162 engaging with each other, and guide the relative movement of the first clamp 104 and the second clamp 106. For example, the guide surface can correct the deviation between the first clamp 104 and the second clamp 106.

[0085] In some embodiments, when the first clamp 104 and the second clamp 106 are closed, their relative positions are limited. For example, the relative positional relationship between the first clamp 104 and the second clamp 106 can be limited by the cooperation of the first positioning part 142 and the second positioning part 162. The first positioning part 142 and the second positioning part 162 facilitate accurate mold closing of the first clamp 104 and the second clamp 106. The first positioning part 142 and the second positioning part 162 can limit the stroke of the second clamp 106 as it moves with the floating member 114, for example, by limiting the compression amount, tilt angle, or rotation angle of the helical spring. This helps to reduce the impact of the floating member 114 on the assembly accuracy of the housing 110 and the window 112.

[0086] In some embodiments, the first clamp 104 includes a first clamping member 144 and a second clamping member 146. The first clamping member 144 and the second clamping member 146 can be used to secure the housing 110. See also Figure 4A and Figure 4B The first clamping member 144 can clamp onto the circumferential edge of the housing 110, for example, the first clamping member 144 can clamp onto both sides of the housing 110. The first clamping member 144 can be fixedly mounted on the body of the first clamp 104. The shape, size, or spacing of the first clamping member 144 matches the shape and size of the housing 110. The first clamping member 144 can limit the position of the housing 110 relative to the first clamp 104.

[0087] In some embodiments, the housing 110 includes a positioning groove. A second clamping member 146 may engage with the positioning groove. For example, the second clamping member 146 may snap into the positioning groove. The interaction between the second clamping member 146 and the positioning groove defines the mounting position of the housing 110 relative to the first clamp 104, which helps to improve the assembly accuracy of the housing 110 and the window 112.

[0088] In some embodiments, the second clamping member 146 is movably disposed on the body of the first clamp 104. For example, the second clamping member 146 includes a wrench. An operator can press the housing 110 against the first clamp 104 by operating the wrench. Automated equipment can also be used to operate the wrench. The first clamping member 144 can define the position and orientation of the housing 110 relative to the first clamp 104. The second clamping member 146 can cooperate with a positioning groove to accurately position the housing 110 and fix the housing to the first clamp 104. This can reduce the risk of displacement of the housing 110 when the first clamp 104 moves the housing 110. In some embodiments, a buffer structure, such as a buffer pad, can be provided to protect the housing 110 and reduce the risk of scratching the housing 110 or deformation of the housing 110 due to excessive pressure. The buffer structure can be disposed at the position where the first clamping member 144 or the second clamping member 146 contacts the housing 110. Alternatively, the buffer structure can be disposed at the position where the first clamp 104 contacts the housing 110.

[0089] See Figure 5 In some embodiments, the second clamp 106 includes at least one limiting member 164 and at least one operating member 166. The at least one limiting member 164 mates with at least a portion of the circumferential edge of the window 112. The window 112 is received within the limiting member 164.

[0090] In some embodiments, the lidar window 112 is a sheet-like structure with uniform thickness and a certain curvature.

[0091] Some embodiments of this disclosure utilize at least one limiting member 164 and at least one operating member 166 to secure the view window 112. The at least one limiting member 164 mates with at least a portion of the circumferential edge of the view window 112. For example... Figure 5 As shown, the second clamp 106 includes three limiting members 164. Two of the limiting members 164 are located at the long edge of the window, and one is located at the short edge of the window. The position of the window is restricted or fixed by the three limiting members 164. Exemplarily, an adjacent long side and a short side of the window abut against the limiting member 164 respectively. By restricting the position of the adjacent long side and a short side, the overall position of the window is defined. Compared to limiting the window from all sides, the second clamp 106 of this embodiment restricts the position of an adjacent long side and a short side of the window. The window has two degrees of freedom in two directions. This can improve the accuracy of limiting or positioning.

[0092] The operating member 166 can fix the relative position of the viewing window 112 and the limiting member 164. The operating member 166 and the limiting member 164 cooperate with each other to fix the viewing window 112. For example, the operating member 166 can abut against the circumferential edge of the viewing window 112, so that the viewing window 112, the limiting member 164, and the operating member 166 all abut against each other to fix the position of the viewing window 112.

[0093] For example, such as Figure 5 As shown, three limiting members 164 are used to restrict the position of one adjacent long side and one adjacent short side of the window. The restricted long side and one adjacent short side of the window form an included angle. An operating member 166 is disposed at the diagonal of the included angle. In this way, the limiting members 164 and the operating member 166 apply pressure to the window from the included angle and the diagonal, respectively. The position of the window can be precisely defined.

[0094] In some embodiments of this disclosure, the second clamp 106 includes a plurality of operating elements 166. The plurality of operating elements 166 may be disposed at different circumferential positions of the window 112 and abut against the circumferential edge of the window 112 or the outer surface of the limiting member 164 from multiple directions.

[0095] See Figure 5 In some embodiments, the operating member 166 includes two abutting claws 1662 and a wrench 1664. One abutting claw 1662 can abut against a long edge of the window. The other abutting claw 1662 can abut against a short edge of the window. The long edge of the abutting claw 1662 is opposite to the long edge of the limiting member 164. The short edge of the abutting claw 1662 is opposite to the short edge of the limiting member 164. The operating wrench 1664 can move the abutting claw 1662 closer to or further away from the window 112.

[0096] When fixing the window 112 using the second clamp 106, the window 112 is placed on the window support surface of the second clamp 106. Three limiting members 164 can limit the position of one adjacent long side and one short side of the window 112. The wrench 1664 is operated so that two abutting claws 1662 respectively abut against the edges of the other long side and the other short side of the window 112. The abutting claws 1662 and the limiting members 164 together press and fix the window 112.

[0097] In some embodiments, after the operating member 166 abuts against the window 112, the forces acting on the window 112 by the operating member 166 and the limiting member 164 remain balanced. The forces acting on the operating member 166 and the limiting member 164 are distributed more evenly within the area of ​​the window 112, reducing the risk of deformation due to force concentration at certain locations of the window 112. For example, the force acting on the window 112 by the operating member 166 is opposite in direction to the force acting on the window 112 by the limiting member 164, and both are directed towards the shape center of the window 112.

[0098] In some embodiments, the limiting member 164 and the operating member 166 have flexible structures on the sides facing the window 112, such as pads or coatings made of rubber or silicone. When the window 112 is secured by the limiting member 164 and the operating member 166, the flexible structure can be used to protect the window 112, reducing the risk of the window 112 being scratched or deformed due to pressure concentration.

[0099] In some embodiments, the operating element 166 further includes a self-locking mechanism. In the unlocked state, the self-locking mechanism allows the abutment claw 1662 to move closer to or further away from the window. In the locked state, the self-locking mechanism keeps the abutment claw 1662 abutting against the window. For example, Figure 5 The wrench 1664 shown can be locked by a self-locking mechanism after being rotated a certain angle, thus fixing the positions of the wrench 1664 and the abutment claw 1662. The relative positional relationship between the abutment claw 1662 and the viewing window 112 remains fixed. The self-locking mechanism eliminates the need for continuous control of the operating element 166, reducing operational difficulty and facilitating automated control. In some embodiments, self-locking can be achieved through the mechanical structure of the wrench 1664. For example, the self-locking mechanism includes a plane that abuts against the wrench 1664. The rotation axis of the wrench 1664 is located in an eccentric position, and self-locking is achieved by utilizing the side shape or stepped structure of the wrench 1664 in conjunction with the plane.

[0100] This disclosure also provides an assembly method. Figure 7A The flowchart illustrates an exemplary assembly method 200 consistent with some embodiments of the present disclosure for assembling the housing and window of a lidar. In some embodiments, the assembly apparatus 100 of the foregoing embodiments may be used to assemble the housing and window of the lidar.

[0101] See Figure 7A In step S202, the outer casing is fixed to the first fixture. This step can be performed manually by an operator. For example, the operator aligns the outer casing with the first fixture and operates the first and second clamping members to clamp the outer casing, thus fixing it to the first fixture. In some embodiments, the step of fixing the outer casing to the first fixture can also be performed using an automated device. For example, an automated device can be installed at the end of the outer casing forming production line or at the end of the outer casing inspection production line. The automated device is connected to the incoming material of the first fixture, can acquire the outer casing and the first fixture, and fix the outer casing to the first fixture.

[0102] In step S204, the window is fixed to the second fixture. This step can be performed manually by an operator. For example, the operator obtains the window, uses a limiting member to define the position of the window in the second fixture, and controls the operating member to abut against the window or the limiting member, cooperating with the limiting member to fix the window. In some embodiments, the step of fixing the window to the second fixture can also be performed by an automated device. For example, a workstation with a second fixture is provided; after the window is attracted or clamped, it is fixed to the second fixture, and the limiting member and the operating member jointly define the position of the window in the second fixture.

[0103] In some embodiments, the execution order of steps S202 and S204 is not limited; either step can be executed first, or they can be executed simultaneously.

[0104] In step S206, the first clamp and the second clamp are mounted on the bracket. In this embodiment, both the first clamp and the second clamp are detachably connected to the bracket. For example, the bracket is fixedly mounted at the assembly station. After the outer shell is fixed to the first clamp, the first clamp can be mounted on the bracket, connecting the outer shell to the first clamp. After the window is fixed to the second clamp, the second clamp can be mounted on the bracket, connecting the window to the second clamp. In some embodiments, the first clamp and the second clamp can be mounted on the bracket first, then the outer shell can be fixed to the first clamp, and the window can be fixed to the second clamp. In the embodiments of this disclosure, the order of steps S206 with steps S202 and S204 is not limited.

[0105] In step S208, adhesive is applied to at least one of the housing or the window. In some embodiments, step S208 is performed after steps S202-S206. The housing and the window remain in a substantially fixed position. Applying adhesive at this time reduces the risk of adhesive contamination. In some embodiments, a dispensing groove may be machined at the window mounting location in the housing. Adhesive may be added to the dispensing groove in this step. The adhesive may include a thermosetting adhesive.

[0106] In step S210, the first clamp and the second clamp are brought closer together so that the housing and the window abut against each other. In this embodiment, the bracket can move the first clamp and the second clamp relative to each other to bring them closer together until the first clamp and the second clamp are closed, and the housing and the window abut against each other. In some embodiments, when the first clamp and the second clamp are closed, there is an interactive pressure between the housing and the window.

[0107] In some embodiments, the assembly method 200 further includes step S212. In step S212, the first clamp and the second clamp are locked together. A locking member is used to keep the first clamp and the second clamp locked. In this case, the housing and the window remain in contact. During the time the first clamp and the second clamp are locked, the adhesive can cure, bonding and fixing the housing and the window together. Furthermore, locking the first clamp and the second clamp helps to stabilize the relative position of the housing and the window, preventing displacement that could lead to adhesive failure or decreased assembly accuracy.

[0108] Figure 7B A flow diagram of an exemplary assembly method 300 consistent with some embodiments of the present disclosure is shown. See also Figure 7B Assembly method 300 includes the process of separating the first clamp and the second clamp from the bracket. Steps S302, S304, S306, S308, S310 and S312 in assembly method 300 are the same as or similar to steps S202, S204, S206, S208, S210 and S212 in assembly method 200 in the foregoing embodiment.

[0109] In step S314, the first clamp and the second clamp are separated from the support. In step S316, the first clamp and the second clamp are locked in place, and the adhesive is cured.

[0110] In some embodiments of this disclosure, the first and second clamps are detachably connected to the bracket. After locking the first and second clamps together in step S312, the first and second clamps remain locked and are then separated from the bracket. The locking of the first and second clamps does not affect the curing of the adhesive. In some embodiments, curing conditions for the adhesive can be provided when performing step S316. For example, if the adhesive includes a thermosetting adhesive, a thermosetting environment can be provided to the first and second clamps after they are separated from the bracket to cure the adhesive.

[0111] In the embodiments of this disclosure, after the first and second clamps are separated from the support, they remain locked, providing conditions for adhesive curing while awaiting curing. This releases the support from its occupancy, leaving it free after the first and second clamps are removed. While waiting for the adhesive to cure, the support, along with the remaining first and second clamps, can be used to assemble the next set of housings and windows. The adhesive curing time does not affect the efficiency of the assembly station. The assembly method 300 of this embodiment improves work efficiency and allows the use of adhesives with longer curing times to assemble housings and windows.

[0112] It should be noted that the above descriptions are merely embodiments of this disclosure and are not intended to limit this disclosure. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
