Description

Technical Field

[0001] This invention relates to the field of smart grid equipment assembly technology, and more particularly to a multi-directional positioning device for assembling cable connectors. Background Technology

[0002] With the development of smart grids, cable connectors 200 are being used more and more as an important component for connecting cables. Please refer to [link / reference]. Figure 1 To ensure reliable connection and stable conductivity, the assembly of the cable connector 200 requires first connecting multiple cables 201 to the housing 202, then placing the conductive terminals 203 into the housing 202, and finally placing metal plates 204 on multiple assembly positions 206 in the housing 202 to fix the metal plates 204, conductive terminals 203, and housing 202 together. Due to the small size, complex structure, and flexible cables of the cable connector 200, it is prone to swaying during assembly. Therefore, the positioning accuracy and precision of the connector 200 are extremely important when assembling it using mechanical equipment. Current methods for assembling these connectors 200 involve manual assembly or semi-automatic assembly using fixtures. This method requires workers to manually and precisely position the connector 200, then place the metal plates 204, and finally perform overall pressing assembly. This demands extremely high precision in the workers' assembly movements, resulting in slow assembly speed and low production efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides a multi-directional positioning device for assembling cable connectors, comprising a frame, a movable stage, a translation drive mechanism, a sliding plate, a first longitudinal drive mechanism, a multi-directional positioning component, a first vertical drive mechanism, a lateral positioning component, a second longitudinal drive mechanism, a longitudinal positioning component, a third longitudinal drive mechanism, a vertical positioning component, and a second vertical drive mechanism; the movable stage is laterally movably disposed on the frame, the translation drive mechanism is disposed on the frame and drives the movable stage to move laterally; the first longitudinal drive mechanism is disposed on the upper side of the movable stage and drives the sliding plate to slide longitudinally; the first vertical drive mechanism is disposed on the upper side of the sliding plate and drives the multi-directional positioning component to move vertically; the positioning head surface of the multi-directional positioning component is provided with a positioning plane to support the connector; the two lateral ends of the positioning head surface are provided with limiting protrusions to restrict the two ends of the connector in the lateral direction; the longitudinal front end of the positioning head is provided with a plurality of openings arranged at lateral intervals through the top and bottom, each of the openings... The opposing inner surfaces restrict the transverse sides of each cable of the connector, and the inner bottom surface of the opening restricts one longitudinal side of the cable; the second longitudinal drive mechanism is disposed under the moving stage and drives the transverse positioning member to move longitudinally, the front end of the transverse positioning member is provided with two forks, and a positioning port is formed between the two forks, the transverse side walls of the positioning port are provided with transverse positioning surfaces to restrict the neck of the fixture used to fix the connector; the third longitudinal drive mechanism is disposed in front of the moving stage and drives the longitudinal positioning member to move longitudinally, the longitudinal positioning member and the inner bottom surface of the opening together restrict the longitudinal movement of the connector; the second vertical drive mechanism is disposed on the upper side of the slide plate and drives the vertical positioning member to move vertically, the vertical positioning member and the multi-directional positioning member together restrict the vertical movement of the connector; the vertical positioning member is provided with a plurality of through holes arranged at transverse intervals, each of the through holes corresponding one-to-one with the assembly position of the connector, so that the workpiece can enter the assembly position of the connector.

[0005] Compared with existing technologies, this invention utilizes a second longitudinal drive mechanism to drive the longitudinal movement of the lateral positioning member, and further utilizes two forks at the front end of the lateral positioning member to laterally position the neck of the fixture. A multi-directional positioning member is also provided, with openings arranged at lateral intervals on its positioning head. The cable is laterally positioned using the two opposite inner sides of these openings, and the longitudinal positioning member is driven longitudinally by the inner bottom surface of the openings and a third longitudinal drive mechanism, thus jointly positioning the connector longitudinally. Furthermore, a positioning plane is provided on the surface of the positioning head of the multi-directional positioning member, with limiting protrusions at both lateral ends of the positioning plane. When the connector is positioned on the positioning plane, the connector can be laterally positioned. In addition, a vertical drive mechanism drives the vertical positioning member to move vertically, so that the vertical positioning member and the positioning plane of the multi-directional positioning member jointly position the connector vertically. Therefore, the multi-directional positioning device of this solution can completely position the connector in the horizontal, vertical and longitudinal directions, and is automatically driven by its respective drive mechanism without manual operation. This is conducive to the automated assembly of connectors, and the positioning is fast and accurate, which greatly improves the assembly efficiency.

[0006] Preferably, the multi-directional positioning member has an alignment groove on at least one side along the lateral direction, and the vertical positioning member has an alignment block corresponding to the alignment groove. When the vertical positioning member and the multi-directional positioning member position the connector, the alignment block is inserted into the alignment groove. By utilizing the cooperation between the alignment block and the alignment groove, the vertical positioning member and the multi-directional positioning member can accurately align when they are close together vertically, thereby ensuring that the relative position is accurate every time the connector is positioned, effectively improving the accuracy of alignment.

[0007] Preferably, the front end face of the longitudinal positioning member is provided with a limiting step, the limiting step having a first side and a second side, and the side of the fixture having a boss. During positioning, the first side of the limiting step engages with the connector to, together with the inner bottom surface of the opening, restrict the longitudinal movement of the connector. The second side of the limiting step engages with the side of the boss during positioning to, together with the inner bottom surface of the positioning port, restrict the longitudinal movement of the fixture. By providing the limiting step, both the fixture and the connector can be longitudinally positioned, ensuring the accuracy of connector positioning.

[0008] Specifically, the first side of the limiting step is provided with a vertically extending clearance groove to accommodate the protrusion of the connector terminal.

[0009] Preferably, the first vertical drive mechanism includes a bracket, a first servo motor, a first lead screw and nut pair, a drive component, and a driven component. The bracket is mounted on the slide plate. The first servo motor is mounted on the bracket, and its output end is connected to the lead screw of the first lead screw and nut pair. The nut of the first lead screw and nut pair is fixedly connected to the drive component. A seat is provided on the slide plate. The drive component is laterally movable and mounted on the seat. A drive ramp is provided on one side of the drive component. The driven component is vertically movable and mounted on the seat. A mating ramp is provided on one side of the driven component, which engages with the drive ramp. The multi-directional positioning component is fixedly mounted on the driven component. When the nut of the first lead screw and nut pair moves laterally, the drive component drives the multi-directional positioning component to move vertically through the driven component. By providing a drive ramp on the drive component and a mating ramp on the driven component, the lateral movement of the drive component driven by the lead screw is converted into vertical movement of the driven component, thereby achieving the purpose of driving the multi-directional positioning component to move vertically. Furthermore, the use of a servo motor and lead screw and nut assembly allows for precise control of the movement distance of the multi-directional positioning component. As a result, it can accurately approach the connector, protecting the connector and accurately controlling the movement stroke of the multi-directional positioning component for different connectors, ensuring the accuracy of vertical positioning.

[0010] Preferably, the translation drive mechanism includes a second servo motor and a second lead screw and nut assembly. The second servo motor is mounted on the frame, and its output end is connected to the lead screw of the second lead screw and nut assembly. The nut of the second lead screw and nut assembly is fixedly connected to the moving stage. By using the second servo motor and the second lead screw and nut assembly to drive the moving stage, the stroke of the moving stage can be precisely controlled, thereby ensuring that the multi-directional positioning components, lateral positioning components, longitudinal positioning components, and vertical positioning components can be accurately aligned with the fixture and connector, and thus ensuring that each positioning component can accurately reach the target position of the connector.

[0011] Preferably, the first longitudinal drive mechanism includes a first cylinder, a first trigger switch, and a trigger element. The output end of the first cylinder is connected to the slide plate. The first trigger switch is disposed on the moving platform, and the trigger element is disposed on the slide plate and directly opposite the first trigger switch. When the trigger element triggers the first trigger switch, the first cylinder stops driving. Using the first cylinder and the first trigger switch to drive the slide plate ensures accurate slide plate travel and simplifies the control of the drive mechanism.

[0012] Preferably, the second longitudinal drive mechanism includes a second cylinder and a connecting block. The output end of the second cylinder is fixedly connected to one end of the connecting block, and the other end of the connecting block is fixedly connected to the bottom surface of the transverse positioning member. By directly driving the transverse positioning member longitudinally with a cylinder, the forks on both sides of the transverse positioning member can simultaneously restrict the transverse direction of the fixture. Therefore, the transverse positioning structure is simplified, and control is very convenient.

[0013] Preferably, the third longitudinal drive mechanism includes a third cylinder, a guide column, a stop block, and a second trigger switch. The front end of the moving platform is provided with a cantilever 23, and the end of the cantilever 23 is provided with a mounting base 24. The third cylinder is mounted on the mounting base 24, and its output end is fixedly connected to the longitudinal positioning member. The guide column is slidably fitted onto the mounting base 24, with one end fixedly connected to the longitudinal positioning member and the other end fixedly connected to the stop block. The second trigger switch is located on the mounting base 24. When the stop block triggers the second trigger switch, the third cylinder stops extending. By setting the guide column and the mounting base 24 on the cantilever 23, utilizing the sliding fit between the guide column and the mounting base 24, and with the cylinder directly driving the longitudinal positioning member, the longitudinal positioning member can move longitudinally stably and accurately, ensuring the smooth and accurate longitudinal stroke of the longitudinal positioning member.

[0014] Preferably, the second vertical drive mechanism includes a vertical cylinder and a connecting plate. The vertical cylinder is disposed on the slide plate and its output end is fixedly connected to one end of the connecting plate. The other end of the connecting plate is connected to the vertical positioning member to drive the vertical positioning member to move vertically. Attached Figure Description

[0036] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] Please see Figures 1 to 9 The present invention relates to a multi-directional positioning device 100 for assembling cable connectors 200, suitable for positioning the cable connectors 200 during assembly. The connectors 200 are mounted on a fixture 300 during assembly. Each connector 200 has multiple assembly positions 206, and each assembly position 206 is provided with an iron plate 204. The multi-directional positioning device 100 for assembling cable connectors 200 includes a frame 1, a moving stage 2, a translation drive mechanism 3, a sliding plate 4, a first longitudinal drive mechanism 5, a multi-directional positioning component 6, a first vertical drive mechanism 7, a transverse positioning component 8, a second longitudinal drive mechanism 9, a longitudinal positioning component 10, a third longitudinal drive mechanism 110, a vertical positioning component 120, and a second vertical drive mechanism 130.

[0038] Please see Figure 4 , Figure 6 and Figure 10 The frame 1 has a horizontally arranged track 11 on its surface, and the moving stage 2 is movably mounted on the frame 1 via the track 11. A translation drive mechanism 3 is mounted on the frame 1 and drives the moving stage 2 to move laterally. The translation drive mechanism 3 includes a second servo motor 31 and a second lead screw and nut assembly 32. The second servo motor 31 is mounted on the frame 1, and its output end is connected to the lead screw of the second lead screw and nut assembly 32. The central axis of the lead screw of the second lead screw and nut assembly 32 is arranged laterally. The nut of the second lead screw and nut assembly 32 is threadedly connected to the lead screw and fixedly connected to the moving stage 2 to drive the moving stage 2 to move laterally. By using the second servo motor 31 and the second lead screw and nut assembly 32 to drive the moving stage 2, the stroke of the moving stage 2 can be precisely controlled, thereby ensuring that the multi-directional positioning component 6, the horizontal positioning component 8, the longitudinal positioning component 10, and the vertical positioning component 120 can be accurately aligned with the fixture 300 and the connector 200, thus ensuring that each positioning component can accurately reach the target position of the connector 200.

[0039] Please see Figure 11The first longitudinal drive mechanism 5 is disposed on the upper side of the movable platform 2 and drives the slide plate 4 to slide longitudinally. Specifically, the surface of the movable platform 2 is provided with a first groove 21 extending in the longitudinal direction, and the slide plate 4 is slidably disposed in the first groove 21. The first longitudinal drive mechanism 5 includes a first cylinder 51, a first trigger switch 52, and a trigger member 53. The first cylinder 51 is disposed on the movable platform 2 and its output end is connected to the slide plate 4 to push the slide plate 4 to move longitudinally. The first trigger switch 52 is disposed on the movable platform 2, and the trigger member 53 is disposed on the slide plate 4 and is directly opposite the first trigger switch 52. When the trigger member 53 triggers the first trigger switch 52, the first cylinder 51 stops driving. Using the first cylinder 51 and the first trigger switch 52 to drive the slide plate 4 to move can ensure the accurate stroke of the slide plate 4 and make the control of the drive mechanism simpler and more convenient.

[0040] Please see Figures 12 to 15The first vertical drive mechanism 7 is disposed on the upper side of the slide plate 4 and drives the multi-directional positioning member 6 to move vertically. The multi-directional positioning member 6 has an L-shaped structure, wherein the lower end has a positioning head 61; the surface of the positioning head 61 of the multi-directional positioning member 6 is provided with a positioning plane 611 to support the connector 200; the two transverse ends of the surface of the positioning head 61 are provided with limiting protrusions 612 to restrict the two ends of the connector 200 in the transverse direction; the longitudinal front end of the positioning head 61 is provided with a plurality of openings 613 arranged transversely through the upper and lower ends, the opposite inner surface 613a of each opening 613 restricts the transverse sides of each cable 201 of the connector 200, and the inner bottom surface 613b of the opening 613 restricts one longitudinal side of the cable 201. The first vertical drive mechanism 7 includes a bracket 71, a first servo motor 72, a first lead screw and nut assembly 73, a drive member 74, and a driven member 75. The bracket 71 is mounted on the slide plate 4. The first servo motor 72 is mounted on the bracket 71, and its output end is connected to the lead screw of the first lead screw and nut assembly 73. The central axis of the lead screw of the first lead screw and nut assembly 73 is arranged laterally. The nut of the first lead screw and nut assembly 73 is threadedly connected to the lead screw. The slide plate 4 is provided with a seat 41. The seat 41 has a first sliding hole 411 that extends laterally through both sides and a second sliding hole 412 that extends laterally on one side. The drive member 74 is laterally slidably disposed in the first sliding hole 411 of the seat 41. The nut of the first lead screw and nut assembly 73 is fixedly connected to the drive member 74 through the second sliding hole 412 via a connecting shaft, so as to drive the drive member 74 to move. The base 41 has a third sliding hole 413 extending longitudinally through the upper and lower sides. The driven member 75 and the multi-directional positioning member 6 are longitudinally slidably disposed within the third sliding hole 413, and the multi-directional positioning member 6 is fixedly connected to the driven member 75. One side of the driving member 74 has a driving inclined surface 741, and one side of the driven member 75 has a mating inclined surface 751 that engages with the driving inclined surface 741. When the nut of the first lead screw nut pair 73 moves laterally, the driving member 74 drives the multi-directional positioning member 6 to move vertically through the sliding engagement of the driving inclined surface 741 and the mating inclined surface 751 of the driven member 75. By providing the driving inclined surface 741 on the driving member 74 and the mating inclined surface 751 on the driven member 75, the lateral movement of the driving member 74 driven by the lead screw is converted into the vertical movement of the driven member 75, thereby achieving the purpose of driving the multi-directional positioning member 6 to move vertically. Furthermore, the use of a servo motor and lead screw and nut pair can precisely control the movement distance of the multi-directional positioning component 6. Therefore, it can accurately approach the connector 200, which can both protect the connector 200 and accurately control the movement stroke of the multi-directional positioning component 6 for different connectors 200, ensuring the accuracy of vertical positioning.

[0041] Please see Figures 16 to 17 The second longitudinal drive mechanism 9 is fixedly connected to the movable stage 2 and located on the lower side of the movable stage 2. The movable stage 2 is provided with a second slide groove 22 extending longitudinally. The second slide groove 22 is located at the inner bottom of the first slide groove 21. The second longitudinal drive mechanism 9 drives the transverse positioning member 8 to move longitudinally along the first slide groove 21. The front end of the transverse positioning member 8 is provided with two forks 81, and a positioning opening 82 is formed between the two forks 81. The transverse side walls of the positioning opening 82 are provided with transverse positioning surfaces 83 to restrict the two side walls 301a of the neck 301 of the fixture 300. The second longitudinal drive mechanism 9 includes a second cylinder 91 and a connecting block 92. The second cylinder 91 is disposed on the movable stage 2 and its output end is fixedly connected to one end of the connecting block 92. The other end of the connecting block 92 is fixedly connected to the bottom surface of the transverse positioning member 8 away from the positioning opening 82. By using a cylinder to directly drive the longitudinal movement of the transverse positioning member 8, the fork arms 81 on both sides of the transverse positioning member 8 can simultaneously restrict the movement of the fixture 300 in the transverse direction. Therefore, the structure of the transverse positioning is simplified and the control is very convenient.

[0042] Please see Figures 18 to 19The third longitudinal drive mechanism 110 is disposed on the front side of the moving stage 2 and drives the longitudinal positioning member 10 to move longitudinally. The longitudinal positioning member 10 and the multi-directional positioning member 6 are located on opposite sides of the connector 200. The longitudinal positioning member 10 has an inverted L-shaped structure. The head of the longitudinal positioning member 10 and the inner bottom surface 613a of the opening 613 together restrict the longitudinal movement of the connector 200. The front end face of the head of the longitudinal positioning member 10 is provided with a limiting step 101. The limiting step 101 is provided with a first side surface 101a and a second side surface 101b. The side of the fixture 300 is provided with a boss 302. The first side surface 101a of the limiting step 101 cooperates with the connector 200 during positioning to restrict the longitudinal movement of the connector 200 together with the inner bottom surface 613b of the opening 613. The second side 101b of the limiting step 101 engages with the side of the boss 302 during positioning, thus restricting the longitudinal movement of the fixture 300 together with the inner bottom surface 82b of the positioning port 82. By setting the limiting step 101, both the fixture 300 and the connector 200 can be positioned longitudinally, ensuring the accuracy of the connector 200's positioning. Specifically, the first side 101a of the limiting step 101 is provided with a vertically extending clearance groove 101c to accommodate the protrusion 205 of the connector 200's terminal. Specifically, the third longitudinal drive mechanism 110 includes a third cylinder 111, a guide post 112, a stop block 113, and a second trigger switch 114. The front end of the moving platform 2 is provided with a cantilever 23, and the end of the cantilever 23 is provided with a mounting base 24. The third cylinder 111 is mounted on the mounting base 24 and its output end is fixedly connected to the longitudinal positioning member 10. The guide post 112 is slidably fitted into the guide hole 241 of the mounting base 24. One end of the guide post 112 is fixedly connected to the longitudinal positioning member 10, and the other end is fixedly connected to the stop block 113. The second trigger switch 114 is located on the mounting base 24. When the stop block 113 triggers the second trigger switch 114, the third cylinder 111 stops extending. By setting guide post 112 and mounting base 24 on cantilever 23, the guide post 112 and mounting base 24 are slidably connected, and the third cylinder 111 directly drives the longitudinal positioning member 10, so that the longitudinal positioning member 10 can move longitudinally stably and accurately, ensuring the smooth and accurate longitudinal stroke of the longitudinal positioning member 10.

[0043] Please see Figure 12 and Figure 20The multi-directional positioning member 6 has an alignment groove 614 on at least one side along the lateral direction, and the head of the vertical positioning member 120 has an alignment block 121 corresponding to the alignment groove 614. When the vertical positioning member 120 and the multi-directional positioning member 6 position the connector 200, the alignment block 121 is inserted into the alignment groove 614. By utilizing the cooperation between the alignment block 121 and the alignment groove 614, the vertical positioning member 120 and the multi-directional positioning member 6 can accurately align when they are close together vertically, thereby ensuring that the relative position is accurate every time the connector 200 is positioned, effectively improving the accuracy of alignment.

[0044] Please see Figure 10 and Figure 21 The second vertical drive mechanism 130 is disposed on one side of the base 41 of the slide plate 4. The base 41 has a fourth sliding hole 414 extending vertically through the upper and lower sides. The vertical positioning member 120 is slidably disposed within the fourth sliding hole 414. The second vertical drive mechanism 130 drives the vertical positioning member 120 to move vertically. The head of the vertical positioning member 120 and the multi-directional positioning member 6 together restrict the vertical movement of the connector 200. The head of the vertical positioning member 120 has a plurality of through holes 120 arranged at horizontal intervals. Each through hole 122 corresponds one-to-one with the assembly position 206 of the connector 200, so that the workpiece can enter the assembly position 206 of the connector 200. The second vertical drive mechanism 130 includes a vertical cylinder 131 and a connecting plate 132. The vertical cylinder 131 is disposed on one side of the seat 41 of the slide plate 4 and its output end is fixedly connected to one end of the connecting plate 132. The other end of the connecting plate 132 is connected to the vertical positioning member 120 to drive the vertical positioning member 120 to move vertically.

[0045] In summary and in combination Figure 3 , Figure 4 , Figures 7 to 9 The working principle of the multi-directional positioning device 100 for assembling cable connectors 200 according to the present invention will be described in detail below: First, after the connector 200 is clamped onto the fixture 300, the cable 201 and the connector 200 extend from the surface of the fixture 300. The fixture 300, carrying the connector 200, is then transported laterally to the multi-directional positioning device 100. Simultaneously, the translation drive mechanism 3 is activated, and the second servo motor 31 drives the second lead screw nut pair 32, causing its nut to move the moving platform 2 laterally to a preset position. Once the fixture 300 is in position, the second longitudinal drive mechanism 9 is activated, and the second cylinder 91 drives the lateral positioning member 8 to move longitudinally. The positioning port 82 of the lateral positioning member 8 engages with the neck 301 of the fixture 300, and the two fork arms 81 are engaged on both sides of the neck 301. The lateral positioning surface 83 of the positioning port 82 is restricted to the two side walls 301a of the neck 301, thereby laterally positioning the fixture 300. Subsequently, the first longitudinal drive mechanism 5 is activated, and the first cylinder 51 pushes the slide plate 4 to move longitudinally, thereby driving the first vertical drive mechanism 7, the multi-directional positioning member 6, the second vertical drive mechanism 130, the vertical positioning member 120, the third longitudinal drive mechanism 110, and the longitudinal positioning member 10 to move. At this time, the inner side surface 613a of the opening 613 of the multi-directional positioning member 6 engages with the cable 201 to restrict the lateral swing of the cable 201. At the same time, the inner bottom surface of the opening 613 restricts the cable 201 to one longitudinal side. Then, the third longitudinal drive mechanism 110 is activated, and the third cylinder 111 pushes the longitudinal positioning member 10 to move longitudinally towards the connector 200, so that the second side surface 101b of the longitudinal positioning member 10 is limited to the side of the boss 302, thereby longitudinally positioning the fixture 300 with the inner bottom surface of the positioning port 82. Furthermore, the second side 101b of the longitudinal positioning member 10 is located on one side of the connector 200, thereby longitudinally positioning the connector 200 with the inner bottom surface of the opening 613. Additionally, when the first vertical drive mechanism 7 is activated, the first servo motor 72 drives the first lead screw and nut pair 73, which in turn drives the drive member 74 to move laterally. Under the action of the drive inclined surface 741 and the mating inclined surface 751, the drive member 74 drives the driven member 75 to move vertically, thereby causing the multi-directional positioning member 6 to move upwards in the vertical direction, so that the positioning plane 611 of the multi-directional positioning member 6 is close to the bottom surface of the connector 200. Simultaneously, the second vertical drive mechanism 130 is activated, and the vertical cylinder 131 drives the vertical positioning member 120 to approach the connector 200 in the vertical direction, so as to vertically position the connector 200 with the positioning plane 611. At this time, the connector 200 can be fully positioned in all directions. After positioning, the through holes 122 correspond one-to-one with the assembly positions 206 of the connector 200. At this time, the iron sheet 204 can be placed on the assembly positions 206 of the connector 200 through the through holes 122.

[0046] Compared with the prior art, the present invention utilizes a second longitudinal drive mechanism 9 to drive the longitudinal movement of the transverse positioning member 8, and provides two forks 81 at the front end of the transverse positioning member 8 to perform transverse positioning of the neck 301 of the fixture 300. Furthermore, a multi-directional positioning member 6 is provided, with openings 613 arranged at transverse intervals on the positioning head 61 of the multi-directional positioning member 6. The two opposite inner sides of the openings 613 are used to position the cable laterally, and the inner bottom surface of the openings 613 and the longitudinal positioning member 10 are driven longitudinally by the third longitudinal drive mechanism 110 to jointly position the connector 200 longitudinally. Moreover, by providing a positioning plane 611 on the surface of the positioning head 61 of the multi-directional positioning member 6, and providing limiting protrusions 612 at both transverse ends of the positioning plane 611, the connector 200 can be laterally positioned when it is on the positioning plane 611. Furthermore, by using a vertical drive mechanism to drive the vertical positioning member 120 to move vertically, the vertical positioning member 120 and the positioning plane 611 of the multi-directional positioning member 6 jointly position the connector 200 vertically. Therefore, the multi-directional positioning device 100 of this solution can completely position the connector 200 laterally, longitudinally, and vertically, and is automatically driven by its respective drive mechanisms without manual operation. This facilitates the automated assembly of the connector 200, and the positioning is fast and accurate, greatly improving assembly efficiency.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the scope of the present invention are still within the scope of the present invention.
