Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, and in particular, to a positioning device. BACKGROUND

[0002] In the process of automation production, a carrier is a carrier of a product, and the carrier carries the product to flow between each machine in the production line to complete production. However, in the related art, a positioning device is generally positioned by a manual positioning method. In the process of processing or assembling a product, the carrier is prone to deviation, resulting in a high product failure rate. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a positioning device to improve the technical problem that the existing carrier is prone to deviation and reduces the product yield.

[0004] An embodiment of the present application provides a positioning device. The positioning device comprises a substrate, a first positioning mechanism, and a second positioning mechanism. The substrate is provided with a limiting protrusion, and the limiting protrusion surrounds an assembly position configured to carry a target object. The first positioning mechanism comprises a first driving assembly and a first abutting piece. The first driving assembly is installed on the substrate, and the first abutting piece is connected with the first driving assembly. The first abutting piece is configured to abut the target object together with the limiting protrusion in a first direction and abut the target object together with the limiting protrusion in a second direction. The second positioning mechanism comprises a second driving assembly and a second abutting piece. The second driving assembly is installed on the substrate, and the second abutting piece is connected with the second driving assembly. The second abutting piece is configured to abut the target object in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0005] In the positioning device, when the target object is placed in the assembly position, the first driving assembly drives the first abutting piece to move in a direction close to the target object. The first abutting piece cooperates with the limiting protrusion to abut the target object in the first direction and the second direction. The second driving assembly drives the second abutting piece to move in a direction close to the target object, and the second abutting piece abuts the target object in the third direction. Thus, the target object can be positioned in the first direction, the second direction, and the third direction, that is, the target object is positioned in three directions, which is beneficial to reduce the risk of deviation of the target object and improve the yield of the product.

[0006] In at least one embodiment, the first abutting piece comprises a first abutting portion and a second abutting portion. The first abutting portion and the second abutting portion are arranged to intersect. When the first abutting piece abuts the target object together with the limiting protrusion, the first abutting portion is configured to abut one of two adjacent side walls of the target object, and the second abutting portion is configured to abut the other of the two adjacent side walls of the target object.

[0007] By setting the first abutting part and the second abutting part, the first positioning mechanism can realize abutting of the target object in two directions (specifically, the first direction and the second direction) by a single first abutting piece, that is, positioning of the target object in two directions, which is beneficial to simplify the structure of the positioning device, reduce the number of abutting pieces, and reduce the production cost.

[0008] In at least one embodiment, the first abutting part has a first abutting surface, and the second abutting part has a second abutting surface. In the third direction, the first abutting surface is perpendicular to the second direction, and the second abutting surface is perpendicular to the first direction.

[0009] By setting the first abutting surface and the second abutting surface, and the first abutting surface being perpendicular to the second direction and the second abutting surface being perpendicular to the first direction, it is beneficial to increase the contact area of the first abutting part with the target object and the contact area of the second abutting part with the target object when the first abutting piece abuts the target object, thereby improving the stability of the first abutting piece abutting the target object and further reducing the risk of the target object deviating.

[0010] In at least one embodiment, the first abutting part and the second abutting part are integrally formed. By using the integrally formed manner, it is not only beneficial to the manufacturing of the first abutting piece and improve the production efficiency, but also beneficial to improve the structural strength of the first abutting piece and prolong the service life.

[0011] In at least one embodiment, the second abutting piece includes a connecting part and a third abutting part, the connecting part is connected with the second driving assembly, and the third abutting part is connected with the connecting part. When the second positioning mechanism abuts the target object, in the third direction, the projection of the third abutting part at least partially overlaps the target object.

[0012] When the target object is placed in the assembly position, the second driving assembly drives the connecting part to move, and then drives the third abutting part to move in the direction close to the target object, until the projection of the third abutting part at least partially overlaps the target object. At this time, the third abutting part can abut the target object in the third direction, that is, realize positioning of the target object in the third direction.

[0013] In at least one embodiment, the number of second abutting pieces is multiple, and the multiple second abutting pieces are all installed on the substrate and located on the side of the assembly position. The multiple second abutting pieces are all connected with the second driving assembly, and the second driving assembly is configured to drive the multiple second abutting pieces to move in the direction close to the assembly position, so that the multiple second abutting pieces jointly abut the target object in the third direction.

[0014] By setting multiple second abutting pieces, it is beneficial to reduce the risk of the target object being warped or deviated during product processing, thereby further improving the stability of the positioning device in positioning the target object.

[0015] In at least one embodiment, the second driving assembly comprises a first driving member and a plurality of transmission members, the first driving member is installed on the base plate, the plurality of transmission members are each installed on the base plate, and the transmission members are configured to be capable of rotating around an axis thereof. Each transmission member comprises a first segment and a second segment connected to each other, the first segment and the second segment are located on two sides of the axis respectively, one of the first segment and the second segment is connected with the first driving member, and the other of the first segment and the second segment is connected with the second abutting member.

[0016] By arranging the plurality of transmission members, the first driving member can drive the plurality of second abutting members to move, which is conducive to reducing the number of driving members and reducing production costs. The first driving member drives the plurality of transmission members to rotate around the rotation shaft thereof, and then drives the second abutting member to move towards the assembly position, so that the second abutting member abuts against the target object in the third direction.

[0017] In at least one embodiment, the second driving assembly comprises a plurality of second driving members, the plurality of second driving members are each installed on the base plate, and each second driving member is connected with a second abutting member.

[0018] By adopting the mode that one second driving member controls the movement of one second abutting member, the flexibility of the positioning device can be improved. When any one or several second abutting members cannot work due to failure, the remaining second abutting members can still work under the action of the corresponding second driving member to abut against the target object, so that the target object can be positioned in the third direction.

[0019] In at least one embodiment, the second driving assembly further comprises an adapter, the adapter is installed on the output end of the first driving member. The adapter is provided with a plurality of first sliding grooves, the first segment of each transmission member is provided with a first sliding part, and the first sliding part is slidingly inserted into the corresponding first sliding groove. Each second abutting member is provided with a second sliding groove, and the second segment of each transmission member is provided with a second sliding part, and the second sliding part is slidingly inserted into the corresponding second sliding groove.

[0020] When the first driving member drives the transmission member to rotate around the rotation shaft thereof, the first sliding part can slide along the first sliding groove, and the second sliding part can slide along the second sliding groove, which is conducive to reducing the risk of motion interference between the first driving member and the transmission member and motion interference between the second abutting member and the transmission member, thereby improving the service life of the positioning device.

[0021] In at least one embodiment, the second driving assembly further comprises a first guide member and a second guide member, the first guide member and the second guide member are each installed on the base plate, the adapter is slidingly connected with the first guide member, and the second abutting member is slidingly connected with the second guide member.

[0022] The first guide and the second guide are arranged to improve the moving accuracy of the second abutting member, so as to ensure that the second abutting member moves to the target position (specifically, the position where the projection of the third abutting part at least partially overlaps the target object) and abuts against the target object along the third direction.

[0037] The following detailed description will further describe the present application with reference to the above drawings. DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0040] The present application provides a positioning device. The positioning device comprises a substrate, a first positioning mechanism and a second positioning mechanism. The substrate is provided with a limiting protrusion, and the limiting protrusion surrounds an assembly position configured to carry a target object. The first positioning mechanism comprises a first driving assembly and a first abutting piece. The first driving assembly is mounted on the substrate, and the first abutting piece is connected with the first driving assembly. The first abutting piece is configured to abut the target object together with the limiting protrusion in a first direction and abut the target object together with the limiting protrusion in a second direction. The second positioning mechanism comprises a second driving assembly and a second abutting piece. The second driving assembly is mounted on the substrate, and the second abutting piece is connected with the second driving assembly. The second abutting piece is configured to abut the target object in a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0041] In the above positioning device, when the target object is placed in the assembly position, the first driving assembly drives the first abutting piece to move in a direction close to the target object. The first abutting piece cooperates with the limiting protrusion to abut the target object in the first direction and the second direction. The second driving assembly drives the second abutting piece to move in a direction close to the target object, and the second abutting piece abuts the target object in the third direction. Thus, the target object can be positioned in the first direction, the second direction and the third direction, that is, the positioning of the target object in three directions is realized, which is beneficial to reduce the risk of target object deviation and improve the yield of products.

[0042] Some embodiments of the present application will be described in detail with reference to the drawings. The following embodiments and features can be combined with each other in the case of no conflict.

[0043] In the present embodiment, the first direction, the second direction and the third direction are defined to be perpendicular to each other. The first direction is the direction parallel to X in the drawing, the second direction is the direction parallel to Y in the drawing, and the third direction is the direction parallel to Z in the drawing.

[0044] For the convenience of reference to the drawing, the first direction is denoted as "first direction X" hereinafter, the second direction is denoted as "second direction Y", and the third direction is denoted as "third direction Z".

[0045] An embodiment of the present application provides a positioning device 100 for fixing a target object (not shown in the drawing). In some embodiments, the target object can be a carrier. It is worth noting that in the automated production process, the carrier usually serves as the carrier of the product (which can be a chip, a circuit board, etc.), and the carrier carries the product to flow between various machines in the production line to complete the production.

[0046] In other embodiments, the target object can also be other objects that need to be positioned, which is not limited in the present application, and those skilled in the art can select according to the actual situation. For the convenience of description, the carrier will be taken as an example for description hereinafter.

[0047] As shown in Figure 1 and Figure 2 , the positioning device 100 comprises a substrate 10, a first positioning mechanism 20 and a second positioning mechanism 30. The substrate 10 is provided with a limiting protrusion 11, and the limiting protrusion 11 surrounds an assembly position 12 configured to carry the carrier. By providing the limiting protrusion 11, the carrier can be preliminarily positioned, which is convenient for subsequent positioning and clamping operations.

[0048] In other embodiments, the substrate 10 is concave to form a positioning groove (not shown in the drawing) to form the assembly position 12. The present application is not limited thereto, and those skilled in the art can select according to the actual situation.

[0049] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the first positioning mechanism 20 comprises a first driving assembly 21 and a first abutting piece 22. The first driving assembly 21 is mounted on the substrate 10, and the first abutting piece 22 is connected with the first driving assembly 21. The first abutting piece 22 is configured to abut the carrier together with the limiting protrusion 11 along the first direction X, and abut the carrier together with the limiting protrusion 11 along the second direction Y.

[0050] Understandably, when the carrier is placed in the assembly position 12, the first driving assembly 21 drives the first abutting member 22 to move towards the carrier. The first abutting member 22 cooperates with the limiting protrusion 11 to abut the carrier along the first direction X and the second direction Y, so as to realize positioning of the carrier in the first direction X and the second direction Y.

[0051] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the second positioning mechanism 30 comprises a second driving assembly 31 and a second abutting member 32. The second driving assembly 31 is installed on the base plate 10, and the second abutting member 32 is connected with the second driving assembly 31. The second abutting member 32 is configured to abut the carrier along a third direction Z.

[0052] Understandably, when the carrier is placed in the assembly position 12, the second driving assembly 31 drives the second abutting member 32 to move towards the carrier, and the second abutting member 32 abuts the carrier along the third direction Z, so as to realize positioning of the carrier in the third direction Z.

[0053] Compared with the existing manual positioning mode of the carrier, the positioning device 100 in the present application can realize positioning of the carrier in the first direction X, the second direction Y and the third direction Z, i.e. positioning of the carrier in three directions, which is beneficial to reduce the risk of deviation of the carrier and improve the yield of products.

[0054] It is worth noting that the action processes of the first positioning mechanism 20 and the second positioning mechanism 30 are not in sequence, and the present application does not limit this. Those skilled in the art can select according to the actual situation.

[0055] In some embodiments, the positioning device 100 can first abut the carrier along the first direction X and the second direction Y through the first positioning mechanism 20, and then abut the carrier along the third direction Z through the second positioning mechanism 30.

[0056] In some embodiments, the positioning device 100 can first abut the carrier along the third direction Z through the second positioning mechanism 30, and then abut the carrier along the first direction X and the second direction Y through the first positioning mechanism 20.

[0057] In some embodiments, as shown in Figure 6 , the first abutting member 22 comprises a first abutting part 221 and a second abutting part 222, and the first abutting part 221 and the second abutting part 222 are arranged intersectingly. When the first abutting member 22 cooperates with the limiting protrusion 11 to abut the carrier, the first abutting part 221 is configured to abut one of the two adjacent side walls of the carrier, and the second abutting part 222 is configured to abut the other of the two adjacent side walls of the carrier, so as to realize positioning of the carrier in the first direction X and the second direction Y.

[0058] By setting the first abutting portion 221 and the second abutting portion 222, the first positioning mechanism 20 can realize abutting in two directions (specifically, the first direction X and the second direction Y) of the carrier by a single first abutting piece 22, that is, realize positioning in two directions of the carrier, which is beneficial to simplify the structure of the positioning device 100, reduce the number of abutting pieces, and reduce the production cost.

[0059] In other embodiments, the number of the first abutting pieces 22 is two, one of the two first abutting pieces 22 abuts the carrier in the first direction X, and the other of the two first abutting pieces 22 abuts the carrier in the second direction Y. The present application does not make a limitation thereon, and a person skilled in the art can select according to the actual situation.

[0060] In some embodiments, as shown in Figure 4 and Figure 6 , the first abutting portion 221 has a first abutting face 2211, and the second abutting portion 222 has a second abutting face 2221. It should be noted that the first abutting face 2211 specifically refers to a face of the first abutting portion 221 abutting the side wall of the carrier, and the second abutting face 2221 specifically refers to a face of the second abutting portion 222 abutting the side wall of the carrier.

[0061] In some embodiments, as viewed in the third direction Z, the first abutting face 2211 is perpendicular to the second direction Y, and the second abutting face 2221 is perpendicular to the first direction X. In other words, the first abutting face 2211 is parallel to the side wall face of the carrier in the first direction X, and the second abutting face 2221 is parallel to the side wall face of the carrier in the second direction Y.

[0062] When the first abutting piece 22 and the limiting protrusion 11 jointly abut the carrier, the first abutting face 2211 and the second abutting face 2221 are completely abutted on the corresponding side wall faces of the carrier, which is beneficial to increase the contact area of the first abutting portion 221 with the carrier and the contact area of the second abutting portion 222 with the carrier, thereby improving the stability of the first abutting piece 22 abutting the carrier and further reducing the risk of the carrier deviating.

[0063] In other embodiments, as viewed in the third direction Z, the first abutting face 2211 can also not be perpendicular to the second direction Y, and the second abutting face 2221 can also not be perpendicular to the first direction X. That is, the first abutting face 2211 is not parallel to the side wall face of the carrier in the first direction X, and the second abutting face 2221 is not parallel to the side wall face of the carrier in the second direction Y, as long as it is ensured that the first abutting portion 221 and the second abutting portion 222 are at least partially abutted on the side wall face of the carrier.

[0064] In some embodiments, the first abutting part 221 and the second abutting part 222 are integrally formed. By using the integrally formed manner, not only the manufacturing of the first abutting part 22 is facilitated, the production efficiency is improved, but also the structural strength of the first abutting part 22 is improved, and the service life is prolonged.

[0065] In some embodiments, as shown in Figure 5 and Figure 7 , the second abutting part 32 comprises a connecting part 321 and a third abutting part 322, the connecting part 321 is connected with the second driving assembly 31, and the third abutting part 322 is connected with the connecting part 321. When the second positioning mechanism 30 abuts against the carrier, viewed along the third direction Z, the projection of the third abutting part 322 at least partially overlaps with the carrier.

[0066] Understandably, when the carrier is placed in the assembly site 12, the second driving assembly 31 drives the connecting part 321 to move, and the connecting part 321 drives the third abutting part 322 to move in the direction close to the carrier, until the projection of the third abutting part 322 at least partially overlaps with the carrier. At this time, the third abutting part 322 can abut against the carrier in the third direction Z, that is, the positioning of the carrier in the third direction Z is realized.

[0067] In some embodiments, the number of the second abutting parts 32 is multiple. The multiple second abutting parts 32 are all installed on the base plate 10 and located at the periphery of the assembly site 12. The multiple second abutting parts 32 are all connected with the second driving assembly 31. The second driving assembly 31 is configured to drive the multiple second abutting parts 32 to move in the direction close to the assembly site 12, so that the multiple second abutting parts 32 jointly abut against the carrier in the third direction Z.

[0068] By setting the multiple second abutting parts 32, it is beneficial to reduce the risk of the carrier being warped or deviated during the product processing, thereby further improving the stability of the positioning device 100 in positioning the carrier.

[0069] Exemplarily, as shown in Figure 1 and Figure 2 , the number of the second abutting parts 32 is two, and the two second abutting parts 32 are both connected with the second driving assembly 31. In other embodiments, the number of the second abutting parts 32 can also be 3, 4, or other numbers, which are not limited in the present application, and the person skilled in the art can select according to the actual situation.

[0070] In some embodiments, as shown in Figure 2 , Figure 5 and Figure 7 , the second driving assembly 31 comprises a first driving part 311 and multiple transmission parts 312. The first driving part 311 is installed on the base plate 10, and the multiple transmission parts 312 are all installed on the base plate 10, and the transmission part 312 is configured to be able to rotate around its own axis.

[0071] Reference should also be made to Figure 8 Each transmission member 312 comprises a first segment 3121 and a second segment 3122 connected to each other, the first segment 3121 and the second segment 3122 are located on two sides of the axis respectively, one of the first segment 3121 and the second segment 3122 is connected with the first driving member 311, and the other of the first segment 3121 and the second segment 3122 is connected with the second abutting member 32.

[0072] It can be understood that when the carrier is placed in the assembly position 12, the first driving member 311 drives the plurality of transmission members 312 to rotate around the rotation shaft thereof, each transmission member 312 drives the corresponding second abutting member 32 to move towards the assembly position 12, and the plurality of second abutting members 32 abut against the carrier in the third direction Z to realize the positioning of the carrier in the third direction Z.

[0073] Through the arrangement of the plurality of transmission members 312, one first driving member 311 can drive the plurality of second abutting members 32 to move, which is beneficial to reduce the number of driving members and reduce the production cost.

[0074] For example, as shown in Figure 7 and Figure 8 , the transmission member 312 is in the shape of a "V". The V-shaped transmission member 312 is rotationally installed on the base plate 10, and the rotation axis of the V-shaped transmission member 312 is located at the intersection position. One side of the V-shaped transmission member 312 is connected with the first driving member 311, and the other side is connected with the connecting portion 321 of the second abutting member 32.

[0075] In other embodiments, the transmission member 312 can also have other shapes, which are not limited in the present application, and those skilled in the art can select according to the actual situation.

[0076] In some embodiments, the second driving assembly 31 comprises a plurality of second driving members (not shown in the figure), and the plurality of second driving members are all installed on the base plate 10, and each second driving member is connected with one second abutting member 32. It can be understood that when the carrier is placed in the assembly position 12, the plurality of second driving members drive the corresponding second abutting members 32 to move towards the carrier, and the plurality of second abutting members 32 abut against the carrier in the third direction Z to realize the positioning of the carrier in the third direction Z.

[0077] By adopting the mode that one second driving member controls one second abutting member 32 to move, the flexibility of the positioning device 100 is improved. When any one or several second abutting members 32 cannot work due to failure, the remaining second abutting members 32 can still work under the action of the corresponding second driving member to abut against the carrier to realize the positioning of the carrier in the third direction Z.

[0078] In some embodiments, as shown in Figure 2、 Figure 7 and Figure 8 As shown in

[0079] When the first driving member 311 drives the transmission member 312 to rotate around the rotation shaft of the first driving member 311, the first sliding part 3123 can slide along the first sliding groove 3131. Through the cooperation of the first sliding groove 3131 and the first sliding part 3123, it is beneficial to reduce the risk of motion interference between the first driving member 311 and the transmission member 312, thereby improving the service life of the positioning device 100.

[0080] In some embodiments, each second abutting member 32 is provided with a second sliding groove 3211, and each transmission member 312 is provided with a second sliding part 3124 which is slidingly inserted into the corresponding second sliding groove 3211.

[0081] When the first driving member 311 drives the transmission member 312 to rotate around the rotation shaft of the first driving member 311, the second sliding part 3124 can slide along the second sliding groove 3211. Through the cooperation of the first sliding groove 3131 and the first sliding part 3123, it is beneficial to reduce the risk of motion interference between the second abutting member 32 and the transmission member 312, thereby further improving the service life of the positioning device 100.

[0082] In other embodiments, other structures can also be used as long as the transmission member 312 does not interfere with the first driving member 311 and the second abutting member 32 in motion, and the present application does not limit this. Those skilled in the art can choose according to the actual situation.

[0083] In some embodiments, as shown in Figure 2 、 Figure 5 and Figure 7 The second driving assembly 31 further comprises a first guide member 314 and a second guide member 315, both of which are mounted on the base plate 10. The adapter 313 is slidingly connected with the first guide member 314, and the second abutting member 32 is slidingly connected with the second guide member 315.

[0084] It can be understood that when the first driving member 311 works, the first driving member 311 drives the adapter 313 to slide along the first guide member 314. At this time, the adapter 313 drives the plurality of transmission members 312 to rotate around the rotation shaft of the adapter 313. Each transmission member drives the corresponding second abutting member 32 to move along the second guide member 315 towards the assembly position 12, and the plurality of second abutting members 32 abut against the carrier in the third direction Z to realize the positioning of the carrier in the third direction Z.

[0085] Through the arrangement of the first guide member 314 and the second guide member 315, the movement accuracy of the second abutting member 32 is improved, so as to ensure that the second abutting member 32 is accurately moved to the target position (specifically, the position where the projection of the third abutting part 322 at least partially overlaps with the carrier) and abuts against the carrier in the third direction Z.

[0086] For example, the working process of the positioning device 100 provided by the present application is as follows: first, the carrier is placed into the assembly position 12. Then, the first driving assembly 21 drives the first abutting member 22 to move towards the carrier. The first abutting member 22 cooperates with the limiting protrusion 11 to abut against the carrier in the first direction X and the second direction Y, and the second driving assembly 31 drives the second abutting member 32 to move towards the carrier. The second abutting member 32 abuts against the carrier in the third direction Z.
