[0089] When using the centering positioning device 100 of the embodiment of the present application to position the first small piece 300 and the second small piece 400, first place the first small piece 300 on the carrying part 1121, and the carrying part 1121 positions the first small piece 300 in the third direction, and then move the first pushing member 12 along the first direction, and the first pushing member 12 drives the first positioning member 16 and the second positioning member 17 to approach each other and position the first small piece 300 in the second direction, and then move the second pushing member 13 along the second direction, and the second pushing member 13 drives the first centering piece 14 and the second centering piece 15 to approach each other and position the first small piece 300 in the first direction, so that the first positioning mechanism 10 accurately positions the first small piece 300 in the first direction, the second direction and the third direction. After the positioning of the first small piece 300 is completed, the second small piece 400 is placed on the second positioning mechanism 20 for centering, and then the second positioning mechanism 20 is installed on the supporting seat 11. At this time, the second small piece 400 is facing the first small piece 300, and the first small piece 300 and the second small piece 400 are glued to complete the accurate assembly of the first small piece 300 and the second small piece 400.

[0090] In this embodiment, the supporting seat 11 includes a seat body 111 and a cover plate 112. The cover plate 112 is covered on the seat body 111. The seat body 111 is provided with a first slide groove 1111, a second slide groove 1112 and a sliding channel 1113. The first slide groove 1111 and the second slide groove 1112 are located on the side of the seat body 111 facing the cover plate 112. There are two first slide grooves 1111. The two first slide grooves 1111 extend along the first direction, and the second slide groove 1112 extends along the second direction. The first slide groove 1111 is located between the two first slide grooves 1111, and the sliding channel 1113 is located below the two first slide grooves 1111. The bearing portion 1121 is located on the cover plate 112. The cover plate 112 is provided with two first avoidance openings 1122 and two second avoidance openings 1123. The two first avoidance openings 1122 are respectively located on both sides of the bearing portion 1121 in the first direction, and the two second avoidance openings 1123 are respectively located on both sides of the bearing portion 1121 in the second direction. The first dividing member 14 and the second dividing member 15 are respectively slidably arranged on the two first sliding grooves 1111 and respectively pass through the two first avoidance openings 1122. The first positioning member 16 and the second positioning member 17 are respectively slidably arranged on the second sliding groove 1112 and respectively pass through the two second avoidance openings 1123. The first pushing member 12 is slidably arranged on the sliding channel 1113. The second pushing member 13 is slidably arranged on the second sliding groove 1112, and the second pushing member 13 is located on one side of the first positioning member 16 in the third direction. The support base 11 is provided with a split structure, which facilitates the installation of the first pusher 12, the second pusher 13, the first dividing member 14, the second dividing member 15, the first positioning member 16, and the second positioning member 17. The first sliding groove 1111, the second sliding groove 1112, and the sliding channel 1113 provided in the base body 111 facilitate the sliding accuracy of the first pusher 12, the second pusher 13, the first dividing member 14, the second dividing member 15, the first positioning member 16, and the second positioning member 17 on the support base 11.

[0091] In this embodiment, the first dividing member 14 and the second dividing member 15 are respectively provided with a first clamping portion 141 and a second clamping portion 151 on the side away from the seat body 111, and the first clamping portion 141 and the second clamping portion 151 respectively pass through the two first avoidance openings 1122, and the first positioning member 16 and the second positioning member 17 are respectively provided with a first abutting portion 161 and a second abutting portion 171 on the side away from the seat body 111, and the first abutting portion 161 and the second abutting portion 171 respectively pass through the two second avoidance openings 1123, the first clamping portion 141 and the second clamping portion 151 clamp and position the first small member 300 in the first direction, and the first abutting portion 161 and the second abutting portion 171 clamp and position the first small member 300 in the second direction.

[0092] In this embodiment, the first pusher 12 is provided with two toggle slots 121 spaced apart along the second direction, the distance between one end of the two toggle slots 121 is smaller than the distance between the other ends of the two toggle slots 121, and the first positioning mechanism 10 further includes two connecting pins 19, which are respectively provided through the first positioning member 16 and the second positioning member 17 and are respectively inserted into the two toggle slots 121. Specifically, the first positioning member 16 and the second positioning member 17 are respectively provided with a first through hole 162 and a second through hole 172, the two connecting pins 19 respectively pass through the first through hole 162 and the second through hole 172 and are respectively inserted into the two toggle slots 121, and the two toggle slots 121 are arranged in an "eight" shape. When the first pusher 12 moves along the first direction, the first pusher 12 pushes the two connecting pins 19 to move through the two toggle slots 121, and the two connecting pins 19 drive the first positioning member 16 and the second positioning member 17 to move closer to or away from each other along the second direction. In this way, by opening two toggle slots 121 on the first pushing member 12, and setting two connecting pins 19 to pass through the first positioning member 16 and the second positioning member 17 respectively and insert into the two toggle slots 121 respectively, the structure is simple and is conducive to improving the accuracy of the first pushing member 12 driving the first positioning member 16 and the second positioning member 17 to move closer to or away from each other.

[0093] In some other embodiments, the two toggle grooves 121 can be respectively opened on the first positioning member 16 and the second positioning member 17, or two inclined protrusions (not shown) can be provided on the first pushing member 12, and the two inclined protrusions are respectively slidably engaged with the first positioning member 16 and the second positioning member 17. Then, the first pushing member 12 can also drive the first positioning member 16 and the second positioning member 17 to move closer to or away from each other. The embodiments of the present application do not make specific limitations on this.

[0094] In this embodiment, the first positioning mechanism 10 further includes a first resetting elastic member 181, which can be a spring. The two ends of the first resetting elastic member 181 are respectively connected to the first pusher 12 and the support seat 11. The first resetting elastic member 181 is used to drive the first pusher 12 to reset, so that the first pusher 12 drives the first positioning member 16 and the second positioning member 17 to move closer to each other. Thus, when the external force is removed from the first pusher 12, the first resetting elastic member 181 drives the first pusher 12 to reset, and the first pusher 12 drives the first positioning member 16 and the second positioning member 17 to move closer to each other and clamp and position the first small piece 300 in the second direction, thereby facilitating improved accuracy and stability of the first positioning mechanism 10 in positioning the first small piece 300 in the second direction.

[0095] In this embodiment, the support base 11 further includes a stopper 113, which is disposed on the base body 111 and blocks one end of the sliding channel 1113. The ends of the two toggle slots 121 that are close to each other are close to the stopper 113. The two ends of the first resetting elastic member 181 are respectively connected to the first pusher 12 and the stopper 113. This facilitates the disassembly and assembly of the first resetting elastic member 181.

[0096] Please refer to Figure 3 and Figure 4 In this embodiment, the first dividing member 14 and the second dividing member 15 have a first abutting inclined surface 143 and a second abutting inclined surface 153, respectively. The second pushing member 13 has a first abutting inclined surface 132 and a second abutting inclined surface 133, respectively, which are arranged opposite to the first abutting inclined surface 143 and the second abutting inclined surface 153. The second pushing member 13 uses the first abutting inclined surface 132 and the second abutting inclined surface 133 to respectively press the first abutting inclined surface 143 and the second abutting inclined surface 153, so that the first dividing member 14 and the second dividing member 15 are moved closer to each other. This helps to improve the accuracy of the second pushing member 13 in driving the first dividing member 14 and the second dividing member 15 to move closer to each other.

[0097] In some other embodiments, inclined pushing grooves (not shown) may be provided on the first dividing member 14 and the second dividing member 15, and the second pushing member 13 may extend into the pushing grooves of the first dividing member 14 and the second dividing member 15, thereby driving the first dividing member 14 and the second dividing member 15 to approach each other during movement. The embodiments of the present application do not make specific limitations on this.

[0098] In this embodiment, the first positioning mechanism 10 further includes a first supporting elastic member 182 and a second supporting elastic member 183. Both the first supporting elastic member 182 and the second supporting elastic member 183 can be springs. The two ends of the first supporting elastic member 182 are connected to the first dividing member 14 and the supporting seat 11, respectively. The two ends of the second supporting elastic member 183 are connected to the second dividing member 15 and the supporting seat 11, respectively. The first supporting elastic member 182 and the second supporting elastic member 183 are used to drive the first dividing member 14 and the second dividing member 15 away from each other. In this way, it is convenient to place the first small part 300 between the first dividing member 14 and the second dividing member 15.

[0099] In this embodiment, the first dividing member 14 and the second dividing member 15 respectively have a first stopper 142 and a second stopper 152 extending into the first chute 1111 and the second chute 1112. The first supporting elastic member 182 and the second supporting elastic member 183 are both located between the first stopper 142 and the second stopper 152. The two ends of the first supporting elastic member 182 respectively abut against the first stopper 142 and the groove wall of the first chute 1111, while the two ends of the second supporting elastic member 183 respectively abut against the groove wall of the second stopper 152 and the second chute 1112. This facilitates assembly of the first supporting elastic member 182 and the second supporting elastic member 183.

[0100] In this embodiment, the second pusher 13 is located on one side of the first positioning member 16 in the third direction and is in sliding contact with the first positioning member 16. The second pusher 13 is provided with a through-hole 131. The width of the through-hole 131 in the second direction is greater than the width of the through-hole 131 in the first direction. The connecting pin 19, which is provided through the first positioning member 16, also passes through the through-hole 131. The first positioning mechanism 10 further includes a floating elastic member 184, which can be a spring. The two ends of the floating elastic member 184 are respectively connected to the second pusher 13 and the first positioning member 16. The floating elastic member 184 is used to drive the second pusher 13 toward the first dividing member 14 and the second dividing member 15. In this way, the second pushing member 13 and the first positioning member 16 are flexibly connected through the connecting pin 19 and the floating elastic member 184. When the first positioning member 16 and the second positioning member 17 position the first small piece 300 in the second direction, the first positioning member 16 drives the second pushing member 13 to abut the first dividing member 14 and the second dividing member 15 through the floating elastic member 184. At this time, the second pushing member 13 pushes the first dividing member 14 and the second dividing member 15 to clamp and position the first small piece 300 in the first direction. The first positioning member 16 and the second positioning member 17 continue to move in the second direction and clamp and position the first small piece 300 in the second direction. Then, the first dividing member 14, the second dividing member 15, the first positioning member 16 and the second positioning member 17 can simultaneously center the first small piece 300 in the first direction and the second direction, thereby improving the accuracy of the first positioning mechanism 10 in positioning the first small piece 300.

[0101] Please refer to the Figure 5In this embodiment, the second positioning mechanism 20 includes an assembly seat 21, a first limiting member 22, a second limiting member 23 and a moving member 24. The assembly seat 21 is detachably connected to the supporting seat 11, the first limiting member 22 and the second limiting member 23 are slidably arranged on the assembly seat 21 and are arranged opposite to each other, and a limiting groove 221 is provided on the side where the first limiting member 22 and the second limiting member 23 are close to each other. The moving member 24 is slidably arranged on the assembly seat 21 and is transmission-connected with the first limiting member 22 and the second limiting member 23. The moving member 24 is used to drive the first limiting member 22 and the second limiting member 23 to move closer to or away from each other, so that when the first limiting member 22 and the second limiting member 23 are close to each other, the groove walls of the two limiting grooves 221 abut against each other and position the second small member 400.

[0102] Specifically, the movable member 24 is slidably disposed on the assembly seat 21 along a first direction, and the first and second limiting members 22, 23 are slidably disposed on the assembly seat 21 along a second direction. When the second positioning mechanism 20 positions the second small component 400, the movable member 24 moves along the first direction on the assembly seat 21, driving the first and second limiting members 22, 23 toward each other along the second direction. The groove walls of the two limiting grooves 221 abut against and position the second small component 400 in the first and second directions. This facilitates improving the accuracy of the second positioning mechanism 20 in positioning the second small component 400.

[0103] In this embodiment, the two side walls of each limiting groove 221 are inclined. When the first limiting member 22 and the second limiting member 23 approach each other, the two side walls of the limiting groove 221 abut against the second small member 400 and simultaneously apply pressure to the second small member 400 in the first direction and the second direction, thereby achieving the centering positioning of the second small member 400.

[0104] In this embodiment, the first limiting member 22 and the second limiting member 23 also have a supporting protrusion 2211 extending to the corresponding limiting groove 221, and the supporting protrusion 2211 is located below the corresponding limiting groove 221. When the groove walls of the two limiting grooves 221 abut and position the second small piece 400, the supporting protrusion 2211 supports and positions the second small piece 400 in the third direction, which is beneficial to improve the accuracy of the second positioning mechanism 20 in positioning the second small piece 400.

[0105] In this embodiment, the assembly base 21 is provided with a first guide groove 2111 and a second guide groove 2112. The first guide groove 2111 extends along a first direction, and the second guide groove 2112 extends along a second direction and intersects with the first guide groove 2111. The moving member 24 is slidably disposed in the first guide groove 2111, and the first limiting member 22 and the second limiting member 23 are slidably disposed in the second guide groove 2112. This helps to improve the sliding accuracy of the moving member 24, the first limiting member 22, and the second limiting member 23 on the assembly base 21.

[0106] In this embodiment, the second positioning mechanism 20 further includes two toggle pins 25, and the movable member 24 is provided with two abutment grooves 241. Both abutment grooves 241 are through grooves. The two abutment grooves 241 are spaced apart along the second direction, and the distance between one end of the two abutment grooves 241 is smaller than the distance between the other ends of the two abutment grooves 241. When the movable member 24 moves along the first direction, the movable member 24 cooperates with the two toggle pins 25 and the two abutment grooves 241 to move the first limiting member 22 and the second limiting member 23 closer to or farther from each other, thereby facilitating improving the accuracy of the movable member 24 in driving the first limiting member 22 and the second limiting member 23 closer to or farther from each other.

[0107] In this embodiment, the support base 11 is provided with a positioning protrusion 1114a, and the assembly base 21 is provided with a positioning hole 2113. The positioning protrusion 1114a is inserted into the positioning hole 2113 to position the assembly base 21 relative to the support base 11. This helps to improve the accuracy of the second positioning mechanism 20 being installed on the first positioning mechanism 10, and further helps to improve the accuracy of the centering positioning device 100 in aligning the second small piece 400 with the first small piece 300.

[0108] In this embodiment, the positioning protrusion 1114a is formed by the portion of the positioning pin 1114 inserted into the support base 11 protruding from the support base 11. In other embodiments, the positioning protrusion 1114a may also be a part of the support base 11, which is not specifically limited in this embodiment of the application.

[0109] In some other embodiments, the positioning protrusion 1114a can also be protruded from the assembly seat 21, and correspondingly, the positioning hole 2113 is opened on the supporting seat 11. The positioning protrusion 1114a inserted into the positioning hole 2113 can also position the position of the assembly seat 21 relative to the supporting seat 11. The embodiments of the present application do not make specific limitations on this.

[0110] In this embodiment, the second positioning mechanism 20 further includes a second resetting elastic member 26, which can be a spring. The two ends of the second resetting elastic member 26 are respectively connected to the movable member 24 and the assembly seat 21. The second resetting elastic member 26 is used to drive the movable member 24 to reset, so that the movable member 24 drives the first limiting member 22 and the second limiting member 23 closer to each other. Thus, when the external force is removed from the movable member 24, the second resetting elastic member 26 drives the movable member 24 to reset, and the movable member 24 drives the first limiting member 22 and the second limiting member 23 closer to each other and clamps and positions the second small member 400, thereby facilitating improved accuracy and stability in the positioning of the second small member 400 by the first limiting member 22 and the second limiting member 23.

[0111] In this embodiment, the assembly base 21 includes an assembly block 211 and a baffle 212. The first guide groove 2111, the second guide groove 2112, and the positioning hole 2113 are all formed in the assembly block 211. The baffle 212 is provided on the assembly block 211 and closes one end of the first guide groove 2111. The ends of the two abutting grooves 241 that are close to each other are close to the baffle 212. The two ends of the second return elastic member 26 are respectively connected to the movable member 24 and the baffle 212. This facilitates the disassembly and assembly of the second return elastic member 26.

[0112] In this embodiment, the second positioning mechanism 20 further includes a receiving seat 27 having a receiving portion 271 for supporting the second small piece 400. The assembly seat 21 is detachably connected to the receiving seat 27, and the receiving portion 271 is located between the first limiting member 22 and the second limiting member 23. When the second positioning mechanism 20 positions the second small piece 400, the assembly seat 21 is first installed on the receiving seat 27, and then the moving member 24 is pushed to move the first limiting member 22 and the second limiting member 23 away from each other. After that, the second small piece 400 is placed on the receiving portion 271 and the moving member 24 is released. Then, the moving member 24, driven by the second return elastic member 26, approaches each other and clamps and positions the second small piece 400. By providing the receiving seat 27, it is convenient to cooperate with the assembly seat 21, the first limiting member 22, the second limiting member 23, and the moving member 24 to accurately position the second small piece 400.

[0113] In this embodiment, a limiting protrusion 272 is provided on the receiving seat 27, and the limiting protrusion 272 is inserted into the positioning hole 2113 to position the assembly seat 21 relative to the receiving seat 27. This is conducive to improving the accuracy of the assembly seat 21 being installed on the receiving seat 27, and further conducive to improving the accuracy of the second positioning mechanism 20 in positioning the second small component 400.

[0114] In this embodiment, the receiving portion 271 is a convex block structure, and the assembly block 211 is provided with an insertion hole 2114. The insertion hole 2114 is arranged opposite the two limiting grooves 221, thereby facilitating the positioning of the second small piece 400 carried by the receiving portion 271 between the two limiting grooves 221. The movable member 24 is provided with an opening 242 arranged opposite the insertion hole 2114. The provision of the opening 242 facilitates the removal and placement of the second small piece 400, and facilitates the dispensing of glue onto the first small piece 300 and the second small piece 400 through the opening 242.

[0115] To sum up, the centering positioning device 100 of the embodiment of the present application is detachably mounted on the first positioning mechanism 10 by setting a second positioning mechanism 20, and the first positioning mechanism 10 is set to include a supporting seat 11, a first pushing member 12, a second pushing member 13, a first centering member 14, a second centering member 15, a first positioning member 16 and a second positioning member 17. When the centering positioning device 100 positions the first small piece 300 and the second small piece 400, the first pushing member 12 drives the first positioning member 16 and the second positioning member 17 to approach each other and position the first small piece 300 in the second direction, the second pushing member 13 drives the first centering member 14 and the second centering member 15 to approach each other and position the first small piece 300 in the first direction, and the second positioning mechanism 20 centers the second small piece 400, so that the second small piece 400 and the first small piece 300 are accurately aligned. Even if the structures of the first small piece 300 and the second small piece 400 vary, the centering positioning device 100 can still accurately position the first small piece 300 and the second small piece 400 because the first positioning mechanism 10 and the second positioning mechanism 20 respectively center the first small piece 300 and the second small piece 400. Thus, the centering positioning device 100 of this embodiment has high versatility, improves positioning accuracy, and reduces costs.
