Description

Technical Field

[0001] This disclosure relates to the field of assembly tooling technology, and in particular to positioning mechanisms and positioning components. Background Technology

[0002] In the field of environmental perception, LiDAR, with its excellent directivity and high focusing capability, is gradually becoming a core component of high-end robots and automotive products. LiDAR has many mechanical parts, making its production process complex. In existing technologies, the main support of the LiDAR needs to change its posture during assembly, thus requiring the main support to be positionable in multiple directions. However, the irregular shape of the main support makes it difficult to position during assembly.

[0003] Therefore, a new positioning mechanism is needed to facilitate the positioning of irregularly shaped parts such as the main support frame, so as to facilitate the assembly of lidar.

[0004] The information in the background section is merely information known only to the inventor and does not imply that such information had entered the public domain before the date of this application, nor does it imply that it can be considered prior art in this disclosure.

[0015] In some embodiments, the limiting portion includes a first inclined surface, the first inclined surface forming an angle of less than 90° with a first direction, and the first inclined surface facing the movable clamping portion. The limiting mating portion includes a second inclined surface, the second inclined surface facing away from the movable clamping portion. The first inclined surface and the second inclined surface are adapted to each other.

[0016] Secondly, this disclosure provides a positioning assembly, which includes the positioning mechanism and the first auxiliary mechanism described in the first aspect. The positioning mechanism includes a third limiting surface and a third positioning portion. The first auxiliary mechanism is detachably connected to the positioning mechanism. The first auxiliary mechanism includes a base. The base includes a fourth limiting surface and a fourth positioning portion, the fourth limiting surface abutting against the third limiting surface along a first direction, and the third positioning portion and the fourth positioning portion forming a pin-hole mating structure extending along the first direction.

[0017] In some embodiments, the first auxiliary mechanism includes a flipping mechanism and a first support portion.

When in the clamping position, the movable clamping part can be positioned opposite the fixed clamping part along a first direction. The rotation angle of the movable clamping part from the clamping position to the open position can be greater than or equal to 90°.

[0038] The following description provides specific application scenarios and requirements for this disclosure, intended to enable those skilled in the art to make and use the content of this disclosure. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this disclosure. Therefore, this disclosure is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0039] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” as used herein may also include the plural forms. When used in this disclosure, the terms “comprising,” “including,” and / or “containing” mean that the associated feature, integer, step, operation, element, and / or component is present, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or the possibility of adding other features, integers, steps, operations, elements, components, and / or groups to the system / method.

[0040] It should be clearly understood that the accompanying drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this disclosure. It should also be understood that the drawings are not drawn to scale.

[0041] In this disclosure, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. That is, X can include only one of A, B, and C, or any combination of A, B, and C, as well as other possible content / elements. The arbitrary combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0042] In this disclosure, unless explicitly stated otherwise, the relationships between structures can be direct or indirect. For example, when describing "A is connected to B," unless it is explicitly stated that A and B are directly connected, it should be understood that A can be directly connected to B or indirectly connected to B. Similarly, when describing "A is above B," unless it is explicitly stated that A is directly above B (AB is adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements, and A is above B). Furthermore, when describing "A is adjacent to B," unless it is explicitly stated that A and B are directly adjacent, it should be understood that A can be directly adjacent to B or separated from B by other components. And so on.

[0043] In the field of environmental perception, LiDAR, with its excellent directivity and high focusing capability, is gradually becoming a core component of high-end robots and automotive products. LiDAR has many mechanical parts, making its production process complex. In existing technologies, the main support of the LiDAR needs to change its posture during assembly to assemble components in multiple directions. This requires the main support to be able to be positioned in multiple directions. However, the irregular shape of the main support makes positioning difficult. Furthermore, changing the posture of the main support can easily lead to contact with the components assembled on it, posing a risk of contamination or damage.

[0044] Therefore, a new positioning mechanism is needed that can facilitate the positioning of irregularly shaped parts such as the main support frame, and can also provide a gripping position for human hands or robotic arms to facilitate the assembly of lidar.

[0045] This disclosure provides the design of at least one positioning mechanism and positioning component through multiple embodiments. One typical design is as follows: the positioning mechanism includes a bracket, a fixed clamping part, a movable clamping part, and a locking part. The fixed clamping part is fixedly connected to one end of the bracket. The fixed clamping part and the bracket cannot move or rotate relative to each other. The fixed clamping part includes a first limiting surface and at least one first positioning part, such as two positioning pins. When assembling a target part, the first limiting surface abuts against and positions the target part along a first direction (e.g., the length direction of the positioning mechanism), while the positioning pins position the target part along a second and a third direction (e.g., the width and height directions of the positioning mechanism). The movable clamping part is rotatably connected to the bracket at the other end and spaced a certain distance from the fixed clamping part along the length direction. The rotation angle range of the movable clamping part is greater than or equal to 90°. When the movable clamping part is fully opened, the space between the fixed clamping part and the movable clamping part can be defined and opened. This facilitates quick installation and removal of the target part on the fixed clamping part. Simultaneously, it allows for the provision of assembly space for the first external part, which is assembled to the target part along the first direction, reducing the risk of interference between the movable clamping part and the first external part. After the fixed clamping part positions the target part, the movable clamping part can close to a position opposite to the fixed clamping part by rotation and / or linear movement, thereby clamping and fixing the target part. The positioning mechanism can lock the movable clamping part in the closed position by a locking part. The locking part is connected to the bracket and is configured to lock the size of the distance between the movable clamping part and the fixed part and / or the rotation angle of the movable clamping part.

[0046] The technical solutions of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. This disclosure uses the positioning component and positioning mechanism to position the main support of a lidar as an example. Those skilled in the art should understand that the positioning component and positioning mechanism can also be applied to other scenarios, and their application in other scenarios is also within the scope of protection of this disclosure.

[0047] In the assembly process described in this disclosure, the entity performing the assembly can be an assembly worker, automated equipment, or a combination of both. For ease of description, the entity performing the assembly will be referred to as the assembler.

[0048] Figure 1 A schematic diagram of the assembly process of the target part and some external parts is shown. Figure 2 This diagram illustrates another assembly process between the target part and some external parts. Among them, Figure 2The assembly process continues Figure 1 The assembly process.

[0049] like Figure 1 and Figure 2 As shown, target component 400 is the main support of the lidar. The first external component 501 can be a chassis, the second external component 502 and the third external component 503 can both be lens barrel supports, and the fourth external component 504 can be a lens barrel support or a circuit board support.

[0050] The target part 400 may be provided with multiple mounting areas for assembling different components. For example, such as Figure 1 The target component 400 includes a first region 410, a second region 420, a third region 430, and a fourth region 440. A first external component 501 can be connected to the first region 410, a second external component 502 can be connected to the second region 420, a third external component 503 can be connected to the third region 430, and a fourth external component 504 can be connected to the fourth region 440. It should be noted that the target component 400 may have more or fewer mounting areas; this application does not impose any limitations on this.

[0051] The target part 400 has a large number of mounting areas, and multiple mounting areas are located at different positions on the target part 400, which makes the positioning of the target part 400 during the assembly process quite difficult.

[0052] In some embodiments, the target part 400 includes a first region 410, a second region 420, a third region 430, and a fourth region 440. The first region 410 is located at the end of the target part 400 in a first direction D1, the second region 420 and the third region 430 are disposed opposite to each other along a second direction D2, and the fourth region 440 is located at the end of the target part 400 in a third direction D3. The first direction D1 is the height direction of the target part 400, the second direction D2 is the width direction of the target part 400, and the third direction D3 is the length direction of the target part 400. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. In some embodiments, the first direction D1 can be any direction of the target part 400.

[0053] Of course, those skilled in the art will understand that the target part 400 presented in this disclosure is merely for illustrating and demonstrating the structure and function of the positioning assembly. The structure of the target part 400 is simply a typical part structure that the positioning assembly in this disclosure can position. The positioning assembly to be described in this disclosure can also be applied to target parts of other shapes to assemble external parts in different positional areas on the target part without departing from the core spirit of this disclosure.

[0054] The following describes how the target part 400 is clamped, positioned, and assembled with external parts by the positioning mechanism. When describing the attitude and structure of the target part 400, this disclosure describes the structure of the target part 400 based on its attitude when it is positioned by the positioning mechanism 100. However, the target part 400 may have other attitudes relative to the positioning mechanism 100 after it is removed from the positioning mechanism 100.

[0055] Figure 3 A schematic diagram of a positioning mechanism for positioning a target part is shown. The positioning mechanism 100 can clamp the target part 400 and perform the first-level positioning of the target part 400. Figure 4 A schematic diagram of a positioning component for positioning a target part is shown. Figure 4 As shown, the target part 400, together with the positioning mechanism 100, can be placed on the auxiliary mechanism for secondary positioning in order to assemble with external parts. Figure 5 A schematic diagram of another positioning component for positioning a target part is shown. Figure 6 A schematic diagram of another positioning component for positioning a target part is shown. For example... Figures 4 to 6 As shown, different auxiliary mechanisms can perform secondary positioning on the positioning mechanism 100 in different postures.

[0056] During the assembly and connection of the target part 400 with external parts, the assembler can use the positioning mechanism 100 or the positioning component 001 to position the target part 400.

[0057] In some embodiments, such as Figure 3 As shown, the positioning mechanism 100 can perform the first-level positioning of the target part 400. When the positioning mechanism 100 positions the target part 400, the positioning mechanism 100 and the target part 400 can remain relatively fixed. In this way, the posture of the target part 400 can be adjusted by adjusting the posture of the positioning mechanism 100, thereby facilitating the assembly of certain external parts on the target part 400.

[0058] For example, first define D4 as the upper part of the optomechanical assembly process ( Figure 4 ).like Figures 1 to 6 As shown, the correspondence between the orientation of the positioning mechanism 100 and the orientation of the target part 400 can be as follows: In the first orientation, the first region 410 of the target part 400 faces upward D4; in the second orientation, the second region 420 of the target part 400 faces upward D4; in the third orientation, the third region 430 of the target part 400 faces upward D4; and in the fourth orientation, the fourth region 440 of the target part 400 faces upward D4.

[0059] like Figures 4 to 6As shown, the auxiliary mechanism can further perform a second-level positioning of the positioning mechanism 100, thereby realizing the positioning of the target part 400 in different postures, so as to facilitate the assembly of various external parts on the target part 400.

[0060] In some embodiments, the positioning component 001 may include multiple auxiliary mechanisms. These auxiliary mechanisms can perform secondary positioning on the positioning mechanism 100 in different postures, thereby achieving positioning of the target part 400 in different postures. In some embodiments, one auxiliary mechanism can perform secondary positioning on the positioning mechanism 100 in different postures. For example, multiple positioning parts may be provided in one auxiliary mechanism to achieve secondary positioning of the positioning mechanism 100 in different postures.

[0061] For example, such as Figures 4 to 6 As shown, the plurality of auxiliary mechanisms include a first auxiliary mechanism 200 and a second auxiliary mechanism 300. The first auxiliary mechanism 200 is detachably connected to the positioning mechanism 100 and is configured to position the positioning mechanism 100 in a first posture. The second auxiliary mechanism 300 is detachably connected to the positioning mechanism 100 and is configured to position the positioning mechanism 100 in a second posture. In some embodiments, the second auxiliary mechanism 300 is further configured to position the positioning mechanism 100 in a third posture. In some embodiments, there may be multiple types of second auxiliary mechanisms 300, one of which is configured to position the positioning mechanism 100 in a fourth posture.

[0062] Reference Figures 1 to 6 The positioning mechanism 100 can position the target part 400 in two ways: a double-end positioning method and a single-end positioning method. The target part 400 also includes a fifth region 450 and a sixth region 460, wherein the fifth region 450 is located at the end of the target part 400 opposite to the fourth region 440, and the sixth region 460 is located at the end of the target part 400 opposite to the first region 410. For example, in the double-end positioning method, the positioning mechanism 100 can position the target part 400 in both the sixth region 460 and the first region 410. In this case, the positioning mechanism 100 can clamp the target part 400 along the first direction D1. In the single-end positioning method, the positioning mechanism 100 can position the target part 400 through the sixth region 460. In this case, the positioning mechanism 100 can avoid the first region 410, exposing the first region 410 so that the first external part 501 can be assembled into the first region 410.

[0063] The dual-end positioning method produces a more stable and reliable positioning effect. The single-end positioning method can position the target part 400 when it lacks a fixed area after some external components have been assembled. Therefore, before the first external component 501 is assembled into the target part 400, dual-end positioning of the target part 400 can be achieved using the first area 410. During and after the assembly of the first external component 501 into the first area 410, the positioning mechanism 100 can position the target part 400 using the single-end positioning method. By switching between dual-end and single-end positioning methods, the positioning mechanism 100 can meet the needs of positioning the target part 400 in complex assembly scenarios.

[0064] Furthermore, when removing external parts assembled on the target part 400 from the target part 400, the positioning mechanism 100 can also be used to position the target part 400. In some embodiments, this disassembly process can be the reverse of the assembly process.

[0065] The structure of the positioning mechanism 100 is described in detail below.

[0066] Figure 7 A schematic diagram illustrates the process of a positioning mechanism's movable clamping part switching between a clamping position and an open position. (See diagram for example.) Figure 3 and Figure 7 As shown, the positioning mechanism 100 may include a bracket 110, a fixed clamping part 120, a movable clamping part 130, and a locking part 140.

[0067] The fixing clamping part 120 is located at one end of the bracket 110 and connected to the bracket 110. The fixing clamping part 120 and the bracket 110 can be directly connected or indirectly connected. In some embodiments, the fixing clamping part 120 is fixedly connected to the bracket 110. In some embodiments, the fixing clamping part 120 and the bracket 110 are integrally formed.

[0068] The fixing clamping part 120 includes a first limiting surface 121 and at least one first positioning part 122. The first limiting surface 121 is configured to abut against the target part 400 along a first direction D1. The at least one first positioning part 122 is configured to position the target part 400 along a second direction D2 and a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The first direction is the normal direction of the first limiting surface 121. The fixing clamping part 120 can be used to position the target part 400.

[0069] In some embodiments, the sixth region 460 of the target part 400 may be provided with a positioning surface that mates with the first limiting surface 121, and a positioning mating part that mates with the first positioning part 122. The fixing clamping part 120 can position the target part 400 through the sixth region 460. For example, as Figure 1 and Figure 7 As shown, the sixth region 460 includes at least two first positioning holes 461; correspondingly, the first positioning part 122 includes at least two first positioning pins 1221. The at least two first positioning pins 1221 correspond to the at least two first positioning holes 461 and are adapted in size and shape. When the first positioning part 122 is coupled to the sixth region 460, the at least two first positioning pins 1221 are inserted into the corresponding at least two first positioning holes 461, thereby achieving positioning of the target part 400. For example, the sixth region 460 may include at least two first positioning pins; correspondingly, the first positioning part 122 may include at least two first positioning holes, wherein the first positioning holes are adapted to the first positioning pins.

[0070] In some embodiments, the end of the first positioning pin 1221 has a guide surface, which can play a guiding role during the process of the first positioning pin 1221 being inserted into the corresponding first positioning hole 461.

[0071] The movable clamping part 130 is located at the other end of the bracket 110 and is rotatably connected to the bracket 110. For example... Figure 7 As shown, the rotation angle range of the movable clamping part 130 is greater than or equal to 90°. The movable clamping part 130 and the fixed clamping part 120 are spaced apart along the first direction D1.

[0072] Figure 8 A cross-sectional structural schematic diagram of a positioning mechanism is shown. In some embodiments, such as... Figure 7 and Figure 8 As shown, the movable clamping part 130 can rotate relative to the bracket 110 about the first rotating axis O1, and the axial direction of the first rotating axis O1 is not parallel to the first direction D1. In some embodiments, the axial direction of the first rotating axis O1 may be perpendicular or approximately perpendicular to the first direction D1. For example, the axial direction of the first rotating axis O1 may be parallel or approximately parallel to the second direction D2. As another example, the axial direction of the first rotating axis O1 may be parallel or approximately parallel to the third direction D3.

[0073] By rotating relative to the bracket 110, the movable clamping part 130 can switch between a clamping position and an open position relative to the fixed clamping part 120. When the movable clamping part 130 is in the clamping position, it is opposite the fixed clamping part 120 along the first direction D1. At this time, the distance between the movable clamping part 130 and the fixed clamping part 120 along the first direction D1 is fixed, and a groove-shaped receiving space 180 is formed between them (see...). Figure 3 The movable clamping part 130 can be opened in the first direction D1 to accommodate the target part 400. When the movable clamping part 130 is in the open position, the accommodating space 180 facing the first limiting surface 121 can be opened in the first direction D1, so that the target part 400 can be easily loaded or removed.

[0074] After the fixed clamping part 120 positions the target part 400, the positioning mechanism 100 can position the target part 400 in a double-end positioning manner. At this time, the movable clamping part 130 can close to the position opposite to the fixed clamping part 120 by rotation and / or linear movement, and abut against the first region 410. The fixed clamping part 120 and the movable clamping part 130 clamp the target part 400 along the first direction D1.

[0075] After the fixed clamping part 120 positions the target part 400, the positioning mechanism 100 can also position the target part 400 in a single-end positioning manner. At this time, the movable clamping part 130 is in the open position, exposing the first region 410 so that the first external part 501 can be assembled into the first region 410 along the first direction D1.

[0076] Figure 9 An exploded structural schematic diagram of the movable clamping portion of a positioning mechanism is shown. In some embodiments, such as... Figure 3 , Figure 7 and Figure 9 As shown, the movable clamping part 130 includes a clamping base plate 131 and a second positioning part 132. The clamping base plate 131 is rotatably connected to the bracket 110, and the rotation angle range of the clamping base plate 131 is greater than or equal to 90°. The second positioning part 132 is connected to the clamping base plate 131, and the second positioning part 132 is configured to position the target part 400 along a second direction D2 and / or a third direction D3.

[0077] The clamping base plate 131 can be directly or indirectly connected to the second positioning part 132. When the second positioning part 132 positions the target part 400 along the second direction D2 and the third direction D3, it can limit the relative displacement between the target part 400 and the movable clamping part 130 along the second direction D2 and the third direction D3, and reduce or avoid tilting of the target part 400. This can improve the positioning effect of the target part 400.

[0078] When the movable clamping part 130 is in the clamping position, the target part 400 is limited by the second positioning part 132 and, in turn, also limits the second positioning part 132, thereby restricting the rotation of the movable clamping part 130 relative to the bracket 110. The movable clamping part 130 can be restricted to the clamping position by the locking part, which facilitates the positioning mechanism 100 to stably clamp and position the target part 400. The locking part will be described in detail later in this disclosure.

[0079] In some embodiments, such as Figure 1 and Figure 7As shown, the first region 410 is provided with at least one second positioning hole 411, and the second positioning part 132 includes at least one second positioning pin 1322. In other embodiments, the first region 410 may include at least one second positioning pin, and the second positioning part 132 may include at least one second positioning hole 411. The at least one second positioning hole 411 and the at least one second positioning pin 1322 correspond to each other and are adapted in size and shape. The structural design of the second positioning hole 411 and the second positioning pin 1322 can refer to the structural design of the first positioning hole 461 and the first positioning pin 1221, and will not be described again here.

[0080] When the second positioning pin 1322 is inserted into the second positioning hole 411, the hole wall of the second positioning hole 411 can abut against the outer peripheral wall of the second positioning pin 1322, thereby restricting the relative displacement between the target part 400 and the movable clamping part 130 along the second direction D2 and the third direction D3, and restricting the rotation of the movable clamping part 130 relative to the bracket 110.

[0081] In some embodiments, such as Figure 3 , Figure 7 and Figure 9 As shown, the movable clamping part 130 also includes a first elastic member 133 and a movable part 134. The first elastic member 133 abuts against the clamping base plate 131 and the movable part 134. The second positioning part 132 is fixedly connected to the movable part 134. The first elastic member 133 can be a spring.

[0082] The first elastic element 133 abuts against the clamping base plate 131 and the movable part 134 respectively, and can undergo elastic deformation. When the movable clamping part 130 abuts against the first region 410 of the target part 400 and applies a clamping force F, the clamping base plate 131 and the movable part 134 slide relative to each other and compress the first elastic element 133. By setting the first elastic element 133 and the movable part 134, the positioning mechanism 100 can still stably clamp the target part 400 even when the target part 400 itself has a large dimensional error, thereby achieving the positioning of the target part 400. In this way, the application range of the positioning mechanism 100 can be improved. For example, along the first direction D1, the movable part 134 has a movable distance of 8 mm relative to the clamping base plate 131. In this way, the movable part 134 and the fixed clamping part 120 can clamp target parts 400 of different sizes, thereby improving the compatibility of the positioning mechanism 100 with the target part 400.

[0083] Furthermore, the deformation of the first elastic element 133 can provide some room for movement for the movable part 134, thus giving the movable part 134 more degrees of freedom. During the process of inserting the second locating pin 1322 into the corresponding second locating hole 411, the movable part 134 can move adaptively, which can reduce the risk of interference between the end of the second locating pin 1322 and the entrance of the second locating hole 411, and facilitate a smooth assembly process.

[0084] In some embodiments, there are multiple first elastic elements 133, which are spaced apart from each other. For example, there are four first elastic elements 133.

[0085] In some embodiments, such as Figure 9 As shown, a guide post 1311 may be provided on the clamping base plate 131, and the extending direction of the guide post 1311 is the same as the deformation direction of the first elastic member 133. One end of the guide post 1311 away from the clamping base plate 131 extends slidably into the interior of the movable part 134. Guided by the guide post 1311, the movable part 134 can move relative to the clamping base plate 131 along the extending direction of the guide post 1311. Multiple guide posts 1311 may be provided.

[0086] In some embodiments, the guide post 1311 and the movable part 134 are clearance-fitted, the presence of which allows the movable part 134 to tilt slightly relative to the clamping substrate 131. This allows the movable part 134 to have more degrees of freedom. During the insertion of the second positioning pin 1322 into the corresponding second positioning hole 411, the movable part 134 can move adaptively, reducing the risk of interference between the end of the second positioning pin 1322 and the entrance of the second positioning hole 411, thus facilitating a smooth assembly process.

[0087] In some embodiments, such as Figure 7 and Figure 9 As shown, the second positioning part 132 includes a guide surface 1321. For example, the guide surface 1321 is a tapered surface formed at the end of the second positioning pin 1322, which serves as a guide during the insertion of the second positioning pin 1322 into the corresponding second positioning hole 411. The guide surface 1321 can reduce the risk of interference between the end of the second positioning pin 1322 and the entrance of the second positioning hole 411, which is beneficial to the smooth assembly process.

[0088] With the target part 400 clamped and positioned by both the fixed clamping part 120 and the movable clamping part 130, the movable clamping part 130 abuts against the first region 410 of the target part 400. The second positioning hole 411 and the second positioning pin 1322 are coupled through a pin-hole engagement structure. When the second positioning pin 1322 is inserted into the second positioning hole 411, the movable clamping part 130 cannot leave the clamping position simply by rotating. Therefore, during the process of switching the movable clamping part 130 from the clamping position to the open position, it can first slide from the clamping position along the first direction D1 away from the fixed clamping part 120 to the transition position, so that the second positioning hole 411 and the second positioning pin 1322 disengage. After the second positioning hole 411 and the second positioning pin 1322 disengage, the movable clamping part 130 can rotate, and then rotate from the transition position to the open position.

[0089] In some embodiments, such as Figure 7 and Figure 8 As shown, the bracket 110 includes a first part 111 and a second part 112. The first part 111 is fixedly connected to the fixed clamping part 120. The second part 112 is rotatably connected to the movable clamping part 130. The second part 112 is also slidably connected to the first part 111 along a first direction D1. In this way, the movable clamping part 130 can slide relative to the fixed clamping part 120 along the first direction D1 when in the clamping position.

[0090] In some embodiments, the first portion 111 and the second portion 112 are slidably connected by a slide rail and slider mechanism. The slide rail 1111 in the slide rail and slider mechanism extends along a first direction D1. For example, the first portion 111 is provided with the slide rail 1111, and the second portion 112 is provided with a slider 1123, which can slide along the extending direction of the slide rail 1111. As another example, the first portion 111 is provided with a slider, and the second portion 112 is provided with the slide rail.

[0091] In some embodiments, such as Figure 7 and Figure 8 As shown, along the first direction D1, a stop 1112 is provided at one end of the slide rail 1111 away from the fixed clamping part 120. The stop 1112 is used to limit the sliding range of the slider 1123 to prevent the slider 1123 from disengaging from the slide rail 1111.

[0092] The locking part 140 is connected to the bracket 110. The locking part 140 is used to lock the size of the gap between the fixed clamping part 120 and the movable clamping part 130 and / or the rotation angle of the movable clamping part 130. In this way, the movable clamping part 130 can remain relatively fixed with the fixed clamping part 120, so that the positioning mechanism 100 can stably clamp and position the target part 400.

[0093] Figure 10 An exploded view of a partial structure of the positioning mechanism is shown. In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the locking part 140 is slidably connected to the first part 111, and the locking part 140 includes a limiting part 141. The second part 112 includes a limiting engagement part 1121. The limiting part 141 and the limiting engagement part 1121 cooperate to lock the relative positions of the first part 111 and the second part 112.

[0094] In some embodiments, the limiting portion 141 includes a protrusion. The limiting mating portion 1121 includes a recess. The locking portion 140 is slidable relative to the first portion 111, allowing the limiting portion 141 to be coupled or decoupled from the limiting mating portion 1121. When the limiting portion 141 is coupled to the limiting mating portion 1121, the relative positions of the first portion 111 and the second portion 112 are locked. When the limiting portion 141 is decoupled from the limiting mating portion 1121, the first portion 111 and the second portion 112 are unlocked, allowing relative movement between them. In other embodiments, the limiting mating portion 1121 includes a protrusion. The limiting portion 141 includes a recess.

[0095] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the sliding trajectory of the locking part 140 relative to the first part 111 is linear. For example, the toggle direction may be perpendicular to the first direction D1. In other embodiments, the sliding trajectory of the locking part 140 relative to the first part 111 may be arc-shaped.

[0096] like Figure 7 , Figure 8 and Figure 10 As shown, the locking part 140 has a locked state and an unlocked state. When the locking part 140 is in the locked state, the limiting part 141 is in the locked position, and the limiting part 141 is coupled with the limiting engagement part 1121, locking the relative sliding of the first part 111 and the second part 112 along the first direction D1. When the positioning mechanism 100 clamps and positions the target part 400, the locking part 140 is in the locked state, which helps the positioning mechanism 100 maintain a stable positioning effect on the target part 400. When the locking part 140 is in the unlocked state, the limiting part 141 is in the unlocked position, and the limiting part 141 is decoupled from the limiting engagement part 1121, releasing the restriction on the relative sliding of the first part 111 and the second part 112. The first part 111 can slide relative to the second part 112 along the first direction D1.

[0097] In some embodiments, such as Figure 8 As shown, the bracket 110 includes a second elastic member 113. Along the first direction D1, the second elastic member 113 abuts against the first portion 111 and the second portion 112 respectively.

[0098] When the limiting part 141 is coupled with the limiting mating part 1121, the second elastic member 113 elastically deforms along the first direction D1, applying an elastic force away from the fixed clamping part 120 to the second part 112. When the limiting part 141 is decoupled from the limiting mating part 1121, the elastic deformation of the second elastic member 113 recovers. The deformation recovery of the second elastic member 113 can drive the second part 112 to slide relative to the first part 111 along the first direction D1, causing the movable clamping part 130 to slide from the clamping position to the transition position along the first direction D1, thereby causing the second positioning hole 411 to disengage from the second positioning pin 1322.

[0099] By setting the second elastic element 113, the operator's operation can be reduced when the assembler removes the target part 400 from the positioning mechanism 100, which is conducive to realizing the "quick release" of the target part 400 on the positioning mechanism 100.

[0100] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the positioning mechanism 100 further includes a third elastic member 150. The third elastic member 150 abuts against the locking part 140 and the first part 111 respectively. When the locking part 140 slides relative to the first part 111 to various positions, the third elastic member 150 is always in a compressed state. Thus, the third elastic member 150 can provide a force to the locking part 140, ensuring that the locking part 140 is stably locked, reducing the possibility of miscoupling between the limiting part 141 and the limiting mating part 1121, and improving the reliability of the positioning mechanism 100. According to some embodiments of this disclosure, the elastic force direction of the third elastic member 150 is a third direction D3.

[0101] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the limiting part 141 includes a first inclined surface 1411, the angle between the first inclined surface 1411 and the first direction D1 is less than 90°, and the first inclined surface 1411 faces the movable clamping part 130. The limiting mating part 1121 includes a second inclined surface 1122, the second inclined surface 1122 facing away from the movable clamping part 130. The first inclined surface 1411 and the second inclined surface 1122 are adapted to each other.

[0102] During the movement of the movable clamping part 130 from the transition position to the clamping position, the second inclined surface 1122 moves closer to the first inclined surface 1411. In this process, the second inclined surface 1122 first approaches the first inclined surface 1411, and then abuts against it. Then, the second inclined surface 1122 disengages from the first inclined surface 1411, causing the limiting part 141 to slide into the limiting mating part 1121 under the elastic force of the third elastic member 150. This reduces the need for operation of the locking part 140 during clamping, facilitating the "quick mounting" of the target part 400 onto the positioning mechanism 100.

[0103] In summary, when the target part 400 is clamped between the fixed clamping part 120 and the movable clamping part 130, the fifth region 450 can face the bottom wall of the groove-shaped receiving space 180. The second region 420, the third region 430, and the fourth region 440 face the outside through the opening of the groove-shaped receiving space 180 to facilitate assembly with corresponding external parts.

[0104] During assembly, the orientation of the target part 400 needs to be adjusted so that the area on the target part 400 to be assembled faces the operating space. For example, ... Figure 4 As shown, the operating space is located above the target part 400 at D4. For example, when the first region 410 is the region to be assembled, the orientation of the target part 400 needs to be adjusted so that the first region 410 faces upward at D4 in order to be assembled with the first external part 501; when the second region 420 is the region to be assembled, the orientation of the target part 400 needs to be adjusted so that the second region 420 faces upward at D4 in order to be assembled with the second external part 502; when the third region 430 is the region to be assembled, the orientation of the target part 400 needs to be adjusted so that the third region 430 faces upward at D4 in order to be assembled with the third external part 503; when the fourth region 440 is the region to be assembled, the orientation of the target part 400 needs to be adjusted so that the fourth region 440 faces upward at D4 in order to be assembled with the fourth external part 504.

[0105] Therefore, in addition to the positioning mechanism 100, the positioning component 001 also needs one or more auxiliary mechanisms to position the orientation of the positioning mechanism 100, thereby assisting the positioning mechanism 100 in positioning one or more orientations of the target part 400.

[0106] The following is a detailed description of the assembly structure of the positioning mechanism 100 and the auxiliary mechanism in the positioning component 001.

[0107] According to some embodiments in this disclosure, such as Figure 4 , Figure 11 and Figure 12As shown, this disclosure provides a positioning component 001. The positioning component 001 may include the positioning mechanism 100 and the first auxiliary mechanism 200 described in any of the above embodiments. Wherein, Figure 11 A schematic diagram of a positioning mechanism is shown. Figure 12 A schematic diagram of the structure of a first auxiliary mechanism is shown.

[0108] As previously described, the first auxiliary mechanism 200 is used to perform a second-level positioning of the positioning mechanism 100 in order to assemble the first external part 501 into the first region 410. The first auxiliary mechanism 200 is detachably connected to the positioning mechanism 100. The first auxiliary mechanism 200 includes a base 210. The base 210 includes a fourth limiting surface 211 and a fourth positioning part 212. The positioning mechanism 100 includes a third limiting surface 161, and a third positioning part 162 is included on the third limiting surface 161. The positioning mechanism 100 cooperates with the first auxiliary mechanism 200 to position the orientation of the target part 400. For example, the first auxiliary mechanism 200 can assist the positioning mechanism 100 in positioning the orientation of the target part 400 so that its first region 410 faces upward D4.

[0109] When positioning the positioning mechanism 400, the fourth limiting surface 211 abuts against the third limiting surface 161 along the first direction D1, and the third positioning part 162 and the fourth positioning part 212 form a pin-hole mating structure extending along the first direction D1. The third limiting surface 161 and the third positioning part 162 are disposed on the outer side of the bracket 110. For example, the third limiting surface 161 and the third positioning part 162 are disposed on the side of the bracket 110 opposite to the groove-shaped receiving space 180. In some embodiments, such as Figure 4 , Figure 11 and Figure 12 As shown, the third positioning part 162 includes at least two third positioning holes 1621 extending along the first direction D1, and the fourth positioning part 212 includes at least two third positioning pins 2121. In other embodiments, the third positioning part 162 includes at least two third positioning pins extending along the first direction D1, and the fourth positioning part 212 includes at least two third positioning holes.

[0110] At least two third positioning holes 1621 and at least two third positioning pins 2121 correspond to each other and are compatible in size and shape. The structural design of the third positioning holes 1621 and the third positioning pins 2121 can refer to the structural design of the first positioning hole 461 and the first positioning pin 1221, and will not be described again here.

[0111] like Figure 4 , Figure 11 and Figure 12As shown, when positioning the positioning mechanism 400, the fourth limiting surface 211 faces upward D4 along the first direction D1. During the assembly process of the positioning mechanism 100 and the first auxiliary mechanism 200, the third positioning hole 1621 and the corresponding third positioning pin 2121 change from a disengaged state to a mating state, forming a hole-pin mating structure, thereby restricting the movement and rotation of the positioning mechanism 100 perpendicular to the first direction D1. In addition, the gravity acting on the positioning mechanism 100 can reduce the risk of the positioning mechanism 100 falling off the first auxiliary mechanism 200. In this way, the first auxiliary mechanism 200 can position the positioning mechanism 100 in the first posture, and position the target part 400 through the positioning mechanism 100 so that its first region 410 faces upward D4, facilitating the assembly of the first external part 501 into the first region 410.

[0112] By using the first auxiliary mechanism 200 to position the positioning mechanism 100, the positioning effect of the target part 400 can be achieved on the one hand, and the positioning mechanism 100 can be quickly disassembled and assembled on the auxiliary mechanism on the other hand.

[0113] In some embodiments, such as Figure 4 and Figure 12 As shown, the first auxiliary mechanism 200 includes a flipping mechanism 220 and a first support portion 230. The flipping mechanism 220 is rotatably connected to the first support portion 230, and the rotation angle range of the flipping mechanism 220 is greater than or equal to 90°. The flipping mechanism 220 also includes a suction cup 221. The first support portion 230 is slidably connected to the base 210 along a first direction D1.

[0114] The flipping mechanism 220 has a pick-up position, a sliding position, and a placement position. The rotation angle of the flipping mechanism 220 from the pick-up position to the sliding position can be greater than or equal to 90°. In the pick-up position, the flipping mechanism 220 can position the first external part 501 via the suction cup 221. The first support portion 230 can slide along the first direction D1 toward the base 210, allowing the flipping mechanism 220 to slide from the sliding position toward the placement position. In the placement position, the flipping mechanism 220 can release the first external part 501.

[0115] like Figure 2 , Figure 4 and Figure 12As shown, during the assembly process of the first external part 501 being assembled into the first region 410, the assembler can use the first auxiliary mechanism 200 and the positioning mechanism 100 to position the target part 400, and adjust the movable clamping part 130 to the open position, so that the first region 410 is exposed. At this time, the flipping mechanism 220 can be in the part-removing position, and the first external part 501 can be sucked up by the suction cup 221. The side of the first external part 501 facing away from the suction cup 221 can be glued and has a pin. Then the flipping mechanism 220 rotates toward the first region 410 to the sliding position, so that the first external part 501 rotates to a position opposite to the first region 410. The first support part 230 drives the flipping mechanism 220 to slide toward the first region 410 to the part-placing position, so that the first external part 501 abuts against the first region 410. In this way, the flipping mechanism 220 can drive the first external part 501 to move stably and accurately to the first region 410, and bond it to the first region 410 by glue. This reduces the risk of vibration and displacement of the first external part 501 relative to the first region 410, and improves the stability of the connection process between the first external part 501 and the first region 410. During this process, the rotation angle range of the flipping mechanism 220 can be greater than or equal to 90°, which reduces the risk of interference between the movable clamping part 130 and the flipping mechanism 220.

[0116] In some embodiments, such as Figure 4 and Figure 12 As shown, the flipping mechanism 220 rotates relative to the first support portion 230 about the second pivot O2. When the first auxiliary mechanism 200 positions the positioning mechanism 100 in the first posture, the first pivot O1 extends along the second direction D2, and the second pivot O2 extends along the third direction D3. This arrangement reduces the risk of interference or collision between the flipping mechanism 220 and the movable clamping portion 130.

[0117] In some embodiments, such as Figure 4 and Figure 12 As shown, the first auxiliary mechanism 200 also includes a first latching part 240. The first latching part 240 is slidably connected to the base 210 along the first direction D1. The flipping mechanism 220 is provided with a second latching part 222, which is configured to cooperate with the first latching part 240.

[0118] In some embodiments, such as Figure 4 and Figure 12 As shown, the first auxiliary mechanism 200 includes a fourth elastic element 231 and a fifth elastic element 241.

[0119] The fourth elastic element 231 abuts against the first support portion 230 and the base 210 along the first direction D1. When the first support portion 230 slides toward the base 210 along the first direction D1, the fourth elastic element 231 elastically deforms. When the fourth elastic element 231 elastically returns to its original position, it can drive the first support portion 230 to reset, causing the flipping mechanism 220 to slide from the placement position to the sliding position.

[0120] The fifth elastic element 241 abuts against the first latching part 240 and the base 210 along the first direction D1. When the first latching part 240 slides towards the base 210 along the first direction D1, the fifth elastic element 241 elastically deforms. When the fifth elastic element 241 returns to its original elastic shape, it can drive the first latching part 240 to reset, causing the flipping mechanism 220 to slide from the placement position to the sliding position.

[0121] In some embodiments, such as Figure 4 and Figure 12 As shown, a pad 213 is provided on the base. The pad 213 is used to support the fourth external part 504 to improve the stability of the assembly process.

[0122] According to some embodiments of this disclosure, such as Figure 5 , Figure 11 and Figure 13 As shown, the positioning assembly 001 also includes a second auxiliary mechanism 300 for assembling the second external part 502 and the third external part 503 onto the target part 400. Figure 13 A schematic diagram of a second auxiliary mechanism is shown.

[0123] As previously described, the two second auxiliary mechanisms 300 are used to perform a second-level positioning of the positioning mechanism 100 so as to assemble the second external part 502 onto the second region 420 of the target part 400, assemble the third external part 503 onto the third region 430 of the target part 400, and assemble the fourth external part 504 onto the fourth region 440 of the target part 400.

[0124] Each second auxiliary mechanism 300 is detachably connected to the positioning mechanism 100, and includes a sixth limiting surface 301 and a sixth positioning portion 302 on the sixth limiting surface 301. The positioning mechanism 100 includes a fifth limiting surface 163 and a fifth positioning portion 164. When positioning the positioning mechanism 100, the sixth limiting surface 301 of the second auxiliary mechanism 300 abuts against the fifth limiting surface 163 of the positioning mechanism 100 along a third direction D3, and the fifth positioning portion 164 of the positioning mechanism 100 and the sixth positioning portion 302 of the second auxiliary mechanism 300 form a pin-hole mating structure extending along a third direction D3.

[0125] Furthermore, the fifth limiting surface 163 and the fifth positioning part 164 are disposed on the outer side of the bracket 110. For example, the fifth limiting surface 163 and the fifth positioning part 164 are disposed on the side of the bracket 110 opposite to the groove-shaped receiving space 180.

[0126] In some embodiments, such as Figure 5 , Figure 11 and Figure 13 As shown, the fifth positioning part 164 includes at least two fourth positioning holes 1641 extending along a third direction D3, and the sixth positioning part 302 includes at least two fourth positioning pins 3021. In other embodiments, the fifth positioning part 164 includes at least two fourth positioning pins extending along a third direction D3, and the sixth positioning part 302 includes at least two fourth positioning holes.

[0127] At least two fourth positioning holes 1641 and at least two fourth positioning pins 3021 correspond to each other and are compatible in size and shape. The structural design of the fourth positioning holes 1641 and the fourth positioning pins 3021 can refer to the structural design of the first positioning hole 461 and the first positioning pin 1221, and will not be described again here.

[0128] like Figure 5 , Figure 11 and Figure 13 As shown, during the assembly process of the positioning mechanism 100 and the second auxiliary mechanism 300, the fifth limiting surface 163 of the positioning mechanism 100 can be oriented towards the sixth limiting surface 301, and the positioning mechanism 100 can be moved closer to the sixth limiting surface 301 along the third direction D3 until the fifth limiting surface 163 abuts against the sixth limiting surface 301. During this process, the fourth positioning hole 1641 and the corresponding fourth positioning pin 3021 change from a disengaged state to a mating state, forming a hole-pin mating structure, thereby restricting the movement and rotation of the positioning mechanism 100 perpendicular to the third direction D3. In this way, the second auxiliary mechanism 300 can position the positioning mechanism 100 and position the target part 400 through the positioning mechanism 100.

[0129] By using the second auxiliary mechanism 300 to position the positioning mechanism 100, the positioning effect of the positioning mechanism 100 can be achieved on the one hand, and the positioning mechanism 100 can be quickly disassembled and installed on the auxiliary mechanism on the other hand.

[0130] In some embodiments, such as Figure 5 , Figure 11 and Figure 13 As shown, the first of the two second auxiliary mechanisms 300 is a lateral auxiliary mechanism 310. The lateral auxiliary mechanism 310 is configured to position the positioning mechanism 100 in the second and third postures such that the second region 420 or the third region 430 of the target part 400 faces upward D4.

[0131] In some embodiments, such as Figure 5 , Figure 11 and Figure 13 As shown, the positioning mechanism 100 includes a first end face 171 and a second end face 172 that are opposite to each other along the second direction D2. The second auxiliary mechanism 300 includes a stepped surface 311 and a ground surface 312. The stepped surface 311 has a first height relative to the ground surface 312 and is used to abut against the first end face 171 or the second end face 172.

[0132] Both the step surface 311 and the ground surface 312 face upwards to D4. A first installation space 315 can be formed above the plane where the step surface 311 is located, and a second installation space 316 can be formed between the plane where the step surface 311 is located and the ground surface 312.

[0133] When the second auxiliary mechanism 300 positions the positioning mechanism 100 in the second posture, the first end face 171 abuts against the step surface 311, and the second end face 172 faces upward D4. At this time, the second region 420 of the target part 400 positioned by the positioning mechanism 100 faces upward D4, and the second external part 502 can be assembled onto the second region 420 within the first mounting space 315.

[0134] When the second auxiliary mechanism 300 positions the positioning mechanism 100 in the third posture, the second end face 172 abuts against the step surface 311, and the first end face 171 faces upward D4. At this time, the third region 430 of the target part 400 positioned by the positioning mechanism 100 faces upward D4, and the third external part 503 can be assembled onto the third region 430 within the first mounting space 315. The second external part 502 can be assembled onto the target part 400 before the third external part 503. During the assembly of the third external part 503 onto the target part 400, the second external part 502 can be accommodated within the second mounting space 316.

[0135] Figure 14 A schematic diagram of another second auxiliary mechanism is shown. In some other embodiments, such as... Figure 6 and Figure 14 As shown, the second of the two second auxiliary mechanisms 300 is a bottom auxiliary mechanism 320. The bottom auxiliary mechanism 320 is configured to position the positioning mechanism 100 in a fourth posture such that the fourth region 440 of the target part 400 faces upward D4.

[0136] In some embodiments, such as Figure 11 , Figure 13 and Figure 14As shown, the positioning mechanism 100 is provided with a set of fifth positioning parts 164. The set of fifth positioning parts 164 can form a pin-hole engagement structure with the sixth positioning part 302 on the bottom auxiliary mechanism 320, and can also form a pin-hole engagement structure with the sixth positioning part 302 on the side auxiliary mechanism 310.

[0137] In some other embodiments, the positioning mechanism 100 is provided with two sets of fifth positioning parts 164. The first set of the two sets of fifth positioning parts 164 forms a pin-hole engagement structure with the sixth positioning part 302 on the bottom auxiliary mechanism 320, and the second set of the two sets of fifth positioning parts 164 forms a pin-hole engagement structure with the sixth positioning part 302 on the side auxiliary mechanism 310.

[0138] In summary, the positioning mechanism 100 provided in this disclosure facilitates the quick installation and removal of the target part 400 on the fixed clamping part 120. When in the clamping position, the movable clamping part 130 can be opposite the fixed clamping part 120 along the first direction D1. The rotation angle of the movable clamping part 130 from the clamping position to the open position can be greater than or equal to 90°. This allows the first region 410 to be exposed along the first direction D1, facilitating the assembly of the first external part 501 into the first region 410, while reducing the risk of interference between the movable clamping part 130 and the first external part 501.
