[0036] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] Please refer toFigure 1 The positioning device 100 for positioning a workpiece includes a positioning assembly 10, a driving assembly 20 connected with the positioning assembly 10, a base 30 rotatably connected with the positioning assembly 10, and an inclining assembly 40 connected with the positioning assembly 10. The workpiece can be a screw, a shell fragment, or the like.

[0038] For the convenience of understanding and description of the embodiments of the present application, a three-dimensional coordinate system is established in some of the drawings. A first direction is an X-axis direction as shown in the drawings, a second direction is a Y-axis direction as shown in the drawings, and a third direction is a Z-axis direction as shown in the drawings. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. Figure 1 Figure 1 Figure 1

[0039] Please refer to Figure 1 and Figure 2 The positioning assembly 10 includes a support 11 rotatably connected with the base 30, a sliding member 12 slidably connected with the support 11, a swing member 13 slidably connected with the sliding member 12, and a positioning member 14 connected with the swing member 13. The support 11, the sliding member 12, the swing member 13, and the positioning member 14 are substantially plate-shaped structures. The support 11 is rotatably connected with the base 30 and connected with the inclining assembly 40. The sliding member 12 is slidably connected with the support 11 along the first direction. The swing member 13 is disposed on a side of the sliding member 12 away from the support 11 and slidably connected with the sliding member 12 along the second direction. The driving assembly 20 is disposed in the support 11 and the sliding member 12 along the third direction and connected with the swing member 13. The positioning member 14 is provided with a receiving groove 141, a sliding surface 142, and a plurality of positioning grooves 143. The receiving groove 141 is disposed on a side of the positioning member 14 away from the swing member 13 and used for receiving a plurality of workpieces to be positioned. The sliding surface 142 is disposed on a groove bottom of the receiving groove 141. The plurality of positioning grooves 143 are disposed adjacent to the sliding surface 142 and spaced apart on the groove bottom of the receiving groove 141, and the positioning grooves 143 are adapted to the workpieces.

[0040] ​​​Therefore, by setting the specific structure of the positioning assembly 10, the driving assembly 20 drives the swing piece 13 to swing along a preset track relative to the support piece 11, so that the plurality of workpieces swing in the receiving groove 141, and meanwhile, the tilting assembly 40 drives the swing piece 13 to reciprocate and rotate by a preset angle along a preset direction relative to the base 30, so as to improve the swing amplitude of the workpieces, so that the plurality of workpieces are randomly moved into the plurality of positioning grooves 143 after swinging, thereby enabling the positioning grooves 143 to position the workpieces to a preset orientation. In addition, by setting the sliding plane 142 at the bottom of the receiving groove 141, the workpieces can smoothly roll in the receiving groove 141, the resistance of the workpieces in the rolling process is reduced, the plurality of workpieces can obtain a greater swing amplitude through the sliding plane 142, so that the moving range of the plurality of workpieces covers the plurality of positioning grooves 143, which is beneficial to quickly and accurately moving the plurality of workpieces into the plurality of positioning grooves 143, and the positioning efficiency is improved.

[0041] It can be understood that the above-mentioned reciprocating rotation in a preset direction refers to the reciprocating rotation of the swing piece 13 on a plane formed by the first direction and the second direction, and the above-mentioned preset angle refers to the rotation angle of the swing piece 13 relative to the base 30. In the present embodiment, the preset angle is 60°.

[0042] Please refer to Figure 2 The support piece 11 includes a support body 111 slidably connected with the sliding piece 12 and a fixed body 112 connected with the support body 111 and vertically extended downward from the lower end of the support body 111. The support body 111 is substantially plate-shaped, the support body 111 is slidably connected with the sliding piece 12 along the first direction, and a through hole 1111 is arranged at the middle position of the support body 111 and penetrates the support body 111 along the third direction, and the through hole 1111 is provided for the driving assembly 20 to pass through. The fixed body 112 is substantially block-shaped, the fixed body 112 is vertically extended downward from the side of the support body 111 away from the sliding piece 12 and connected with the fixed body 112, and the fixed body 112 is provided with a receiving groove 1121.

[0043] The sliding piece 12 is provided with a through hole 121 penetrating the sliding piece 12 along the third direction, and the through hole 121 is provided for the driving assembly 20 to pass through.

[0044] The driving assembly 20 includes a connecting piece 21 connected with the swing piece 13, a linkage piece 22 connected with the connecting piece 21, and a swinging driving piece 23 connected with the linkage piece 22. The connecting piece 21 is substantially disc-shaped, the connecting piece 21 is movably passed through the through hole 1111 and the through hole 121 along the third direction and connected with the swing piece 13. The linkage piece 22 is substantially circular rod-shaped, the linkage piece 22 is movably passed through the through hole 121 and the through hole 1111 along the third direction and connected with the connecting piece 21, and the linkage piece 22 is arranged in a different axis with the connecting piece 21. The swinging driving piece 23 is arranged on the side of the fixed body 112 away from the sliding piece 12 and coaxially connected with the linkage piece 22.

[0045] Exemplarily, the shaking driving member 23 can be an electric motor or a rotary cylinder. The aforesaid off-axis arrangement refers to that the central axis of the linkage member 22 is not on the same axis as the central axis of the connecting member 21.

[0046] In this way, by setting the specific structure of the driving assembly 20, the shaking driving member 23 drives the linkage member 22 to drive the connecting member 21 to rotate. Since the linkage member 22 and the connecting member 21 are arranged off-axis, the connecting member 21 drives the positioning member 14 to perform eccentric circular motion relative to the linkage member 22, so as to drive the workpieces in the receiving groove 141 to shake, thereby ensuring that the workpieces are shaken into the corresponding positioning grooves 143, and improving the positioning efficiency of the workpieces.

[0047] The connecting member 21 includes a connecting body 211 in a substantially disc shape connected with the linkage member 22, and a limiting body 212 in a substantially strip shape abutting against the linkage member 22. The connecting body 211 is arranged off-axis with the linkage member 22, and is provided with a mounting hole 2111 penetrating through the connecting body 211 along the third direction for the linkage member 22 to pass through, and a communication groove 2112 formed on the inner wall of the mounting hole 2111. The limiting body 212 is inserted into the communication groove 2112 and abuts against the circumferential side of the linkage member 22.

[0048] In this way, the limiting body 212 abuts against the circumferential side of the linkage member 22 to limit the mutual rotation of the connecting body 211 and the linkage member 22, thereby ensuring the stable connection of the connecting body 211 and the linkage member 22, and ensuring that the linkage member 22 stably drives the connecting body 211 to rotate, thereby improving the driving stability of the driving assembly 20.

[0049] The aperture area of the through hole 121 in the first direction is greater than the cross-sectional area of the connecting body 211.

[0050] In this way, by setting the aperture area of the through hole 121 to be greater than the cross-sectional area of the connecting body 211, the through hole 121 can provide a large enough space for the connecting body 211 to move stably in the through hole 121, thereby avoiding the interference between the connecting body 211 and the sliding member 12.

[0051] Please refer to Figure 1The base 30 comprises a plate-shaped body 31 arranged below the support body 111, bearing bodies 32 embedded in the body 31, and rotating bodies 33 movably penetrating the bearing bodies 32 and the support body 111. The body 31 is arranged below the support body 111 along the third direction. The number of bearing bodies 32 is two, and the two bearing bodies 32 are arranged in the body 31 along the first direction. The number of rotating bodies 33 is two and corresponds to the two bearing bodies 32 one by one. The rotating bodies 33 are substantially rod-shaped, movably penetrate the corresponding bearing bodies 32 and the support body 111 along the first direction, and are rotatably connected with the support body 111 and the bearing bodies 32, respectively.

[0052] Please continue to read Figure 1 The tilt assembly 40 is connected with the positioning assembly 10 and comprises a block-shaped movable piece 41 movably connected with the support piece 11, a rod-shaped lead screw piece 42 movably penetrating the movable piece 41, a tilt driving piece 43 connected with the lead screw piece 42, and a limiting piece 44 connected with the base 30. The movable piece 41 is movably connected with the support piece 11. The lead screw piece 42 movably penetrates the movable piece 41 along the third direction and is threadedly connected with the movable piece 41. The tilt driving piece 43 is connected with the lead screw piece 42. The tilt driving piece 43 drives the lead screw piece 42 to rotate relative to the movable piece 41, so that the movable piece 41 reciprocates in the third direction, thereby driving the support piece 11 to reciprocate in the preset direction. The limiting piece 44 is connected with the base 30 and is provided with a limiting hole 441 receiving one end of the lead screw piece 42 adjacent to the support piece 11, so as to limit the rotating direction of the lead screw piece 42. Exemplarily, the lead screw piece 42 can be a lead screw, and the tilt driving piece 43 can be composed of a rotary motor and a speed reducer. The speed reducer is vertically connected with the rotary motor, and the lead screw piece 42 is connected with the speed reducer.

[0053] In this way, by arranging the specific structure of the tilt assembly 40, the tilt driving piece 43 drives the lead screw piece 42 to rotate relative to the movable piece 41. The lead screw piece 42 is threadedly connected with the movable piece 41, so that the movable piece 41 reciprocates in the third direction under the driving of the lead screw piece 42, thereby driving the support piece 11 to reciprocate in the preset direction, achieving precise and stable control of the tilt angle of the positioning piece 14, and facilitating the provision of the shaking amplitude of the workpiece in the receiving groove 141. In addition, the limiting hole 441 receives one end of the lead screw piece 42 adjacent to the support piece 11, so as to limit the rotating direction of the lead screw piece 42, avoiding shaking or deviation of the lead screw piece 42, ensuring stable operation of the tilt assembly 40, and improving the positioning stability.

[0054] Please continue to read Figure 1The movable part 41 comprises a substantially rod-shaped abutting body 411 inserted into the accommodating groove 1121, a substantially plate-shaped supporting body 412 connected with the abutting body 411, and a substantially block-shaped movable body 413 sleeved on the screw rod 42. The abutting body 411 is inserted into the accommodating groove 1121, the supporting body 412 is connected with the abutting body 411, the movable body 413 is sleeved on the screw rod 42 and is threadedly connected with the screw rod 42, and the movable body 413 is connected with the supporting body 412. The movable body 413 reciprocates in the third direction under the driving of the screw rod 42, so that the abutting body 411 abuts against the groove wall of the accommodating groove 1121 and slides relative to the fixed body 112, thereby driving the supporting body 111 to reciprocate in the preset direction.

[0055] Thus, by arranging the specific structure of the movable part 41, the abutting body 411 is inserted into the accommodating groove 1121 of the supporting part 11, the movable body 413 reciprocates in the third direction under the driving of the screw rod 42, the abutting body 411 abuts against the groove wall of the accommodating groove 1121 and slides relative to the fixed body 112, thereby stably driving the supporting body 111 to reciprocate in the preset direction, and the positioning precision and stability of the positioning device 100 are improved.

[0056] Please refer to Figure 3 The positioning device 100 further comprises a stop assembly 50 connected with the positioning assembly 10 and comprising a substantially plate-shaped fixed part 51 connected with the base 30 and a stop part 52 connected with the supporting part 11. The fixed part 51 is connected with the base 30 and is provided with an accommodating hole 511. The stop part 52 is arranged on the side of the supporting part 11 away from the sliding part 12 and is connected with the supporting part 11. After the workpiece is positioned in the positioning groove 143, the stop part 52 is inserted into the accommodating hole 511 to limit the orientation of the supporting part 11. Exemplarily, the stop part 52 can be a stop part, a stop body or a similar stop block capable of being inserted into the accommodating hole 511, for example, a stop rod connected with a pneumatic cylinder.

[0057] Thus, by arranging the stop assembly 50, after the workpiece is positioned in the positioning groove 143, the stop part 52 is inserted into the accommodating hole 511 of the fixed body 112, thereby limiting the orientation of the supporting part 11 and preventing the supporting part 11 from rotating after positioning due to external force or other factors, ensuring the positioning stability of the workpiece and facilitating the removal of the positioned workpiece.

[0058] The working process of the positioning device 100 is as follows:

[0059] Firstly, the receiving groove 141 receives a plurality of workpieces to be positioned;

[0060] Then, the shaking driving member 23 drives the linkage 22 to drive the connecting member 21 to rotate, the connecting member 21 drives the positioning member 14 to make eccentric circular motion relative to the linkage 22 through the linkage 22 and the connecting member 21 being arranged in different shafts, so that the positioning member 14 drives the workpieces in the receiving groove 141 to shake, at the same time, the inclined driving member 43 drives the screw rod member 42 to rotate relative to the movable member 41, the movable member 41 reciprocates along the third direction under the driving of the screw rod member 42 due to the screw connection between the screw rod member 42 and the movable member 41, and then drives the support member 11 to reciprocate along the preset direction, so that the plurality of workpieces roll in the receiving groove 141 to the positioning groove 143 to position the workpieces, thereby realizing fast and accurate positioning of the workpieces and improving the positioning efficiency.

[0061] Finally, after the workpieces are positioned in the positioning groove 143, the stop member 52 can be inserted into the accommodating hole 511 of the fixed body 112, thereby limiting the orientation of the support member 11, preventing the support member 11 from rotating after positioning due to external force and other factors, ensuring the positioning stability of the workpieces, and facilitating the taking away of the positioned workpieces.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.

The limiting body is inserted into the connecting groove and abuts against the periphery of the linkage to limit the rotation of the linkage relative to the connector.
