[0083] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0084] Please refer to Figure 1 , Embodiment of the present application provides a positioning device 100. The positioning device 100 is used to position a workpiece (not shown in the figure), where the workpiece can be an electric core or other objects. For the convenience of understanding and description, the XYZ coordinate system shown in Figure 1 is defined in the embodiment of the present application. Among them, the X-axis direction is defined as the first direction, and the Y-axis direction is defined as the second direction. It can be understood that this is not a limitation on the embodiment of the present application.

[0085] Please refer to Figure 1 and Figure 2 , The positioning device 100 includes a base 10, a stage 20, a positioning mechanism 30, and a driving mechanism 40. The base 10 is used to install the stage 20, the positioning mechanism 30, and the driving mechanism 40, so that the positioning device 100 can be modularly arranged.

[0086] The stage 20 is connected to the base 10, and the stage 20 has a surface 21 facing away from the base 10. The surface 21 is used to adapt to and carry the workpiece.

[0087] The positioning mechanism 30 includes a first push block 31, a second push block 32, a third push block 33, a fourth push block 34 and a reset member 35. The first push block 31 and the second push block 32 are respectively arranged on opposite sides of the base 10 along a first direction, and the second push block 32 is slidably arranged on the base 10 along the first direction, and the third push block 33 and the fourth push block 34 are respectively slidably arranged on the other opposite sides of the base 10 along a second direction, the second direction is perpendicular to the first direction, and the first push block 31, the second push block 32, the third push block 33 and the fourth push block 34 are away from the base 10. The first push block 31, the second push block 32, the third push block 33 and the fourth push block 34 are all extended to the load surface 21 at one end to position the workpiece carried by the load surface 21, that is, the first push block 31, the second push block 32, the third push block 33 and the fourth push block 34 are extended to the upper side of the load surface 21 at one end away from the base 10 to fit and press against the workpiece, thereby positioning the workpiece, and the reset member 35 is connected between the second push block 32 and the base 10, and the reset member 35 can be a spring, and the compression and extension directions of the reset member 35 are both along the first direction, that is, the reset member 35 can provide the second push block 32 with an elastic force to move toward the first push block 31. Among them, the first push block 31 is fixedly arranged on the base 10 to serve as a reference for the workpiece to press against, and the second push block 32, the third push block 33 and the fourth push block 34 are slidably arranged on the base 10 so as to leave space for placing the workpiece on the load surface 21 and to cooperate with the workpiece to press against the first push block 31.

[0088] The driving mechanism 40 is disposed on the base 10 and is connected to the second push block 32, the third push block 33 and the fourth push block 34 respectively. The driving mechanism 40 is used to drive the second push block 32 to move away from the first push block 31 along the first direction, and to drive the third push block 33 and the fourth push block 34 to move closer to or away from each other along the second direction, wherein the second push block 32 moves closer to the first push block 31 under the elastic force of the reset member 35, and the third push block 33 and the fourth push block 34 move closer to or away from each other along the second direction to center the workpiece.

[0089] When the above-mentioned positioning device 100 positions a workpiece, the driving mechanism 40 drives the second pushing block 32 to move away from the first pushing block 31 in the first direction and compresses the reset member 35 by the second pushing block 32, so that the reset member 35 has a greater elastic force. In addition, the driving mechanism 40 drives the third pushing block 33 and the fourth pushing block 34 to move away from each other in the second direction, so as to leave space for placing the workpiece. After the workpiece is placed on the loading surface 21 of the loading platform 20, the second pushing block 32 moves close to the first pushing block 31 in the first direction under the elastic force of the reset member 35, so that the second pushing block 32 and the first pushing block 31 clamp and position the workpiece in the first direction. Moreover, the second pushing block 32 elastically abuts against the workpiece under the elastic force of the reset member 35. The driving mechanism 40 drives the third pushing block 33 and the fourth pushing block 34 to move close to each other in the second direction, so that the third pushing block 33 and the fourth pushing block 34 position the workpiece in the second direction. In addition, the third pushing block 33 and the fourth pushing block 34 also center the workpiece by moving close to each other, so as to realize the positioning of the workpiece. When the workpiece needs to be taken out, the driving mechanism 40 drives the second pushing block 32 to move away from the first pushing block 31 in the first direction, and drives the third pushing block 33 and the fourth pushing block 34 to move away from each other in the second direction, so as to leave space for taking out the workpiece. At the same time, after the workpiece is taken out, other workpieces can be continuously placed for continuous operation.

[0090] In order to detect whether the workpiece is placed on the loading surface 21, in this embodiment, the positioning device 100 further includes a detector 50. The detector 50 is embedded in the loading surface 21, and the detector 50 is used to detect the workpiece carried by the loading surface 21. Among them, the detector 50 can be a distance sensor, an infrared sensor or other functional objects capable of detecting the workpiece. The loading platform 20 is provided with an assembly groove 22 recessed inward from the loading surface 21. The assembly groove 22 generally extends to the middle of the loading surface 21, and the detector 50 is arranged in the assembly groove 22. In this way, by arranging the above-mentioned detector 50, when the workpiece is placed on the loading surface 21, if the detector 50 detects a signal value, it indicates that the workpiece is placed on the loading surface 21. If the detector 50 fails to detect a signal value, it indicates that the workpiece is not placed on the loading surface 21, so as to realize the detection of whether the workpiece is placed on the loading surface 21. In addition, by embedding the detector 50 in the loading surface 21, the flatness of the loading surface 21 is ensured, so that the workpiece can be flatly attached to the loading surface 21, and the processing yield of the workpiece is ensured.

[0091] Please refer to Figure 3 and Figure 4, in this embodiment, first avoidance grooves 23, second avoidance grooves 24, third avoidance grooves 25 and fourth avoidance grooves 26 are respectively formed on four peripheral sides of the stage 20. Among them, the first push block 31, the second push block 32, the third push block 33 and the fourth push block 34 respectively pass through the first avoidance groove 23, the second avoidance groove 24, the third avoidance groove 25 and the fourth avoidance groove 26, and the second push block 32, the third push block 33 and the fourth push block 34 respectively move in the corresponding second avoidance groove 24, third avoidance groove 25 and fourth avoidance groove 26. In this way, by providing the above-mentioned first avoidance groove 23, second avoidance groove 24, third avoidance groove 25 and fourth avoidance groove 26 on the stage 20, the ends of the first push block 31, the second push block 32, the third push block 33 and the fourth push block 34 facing away from the base 10 extend above the loading surface 21, so as to facilitate the positioning of the workpiece.

[0092] The driving mechanism 40 includes a driving component 41, a pushing member 42, a linkage component 43, a tension spring 44, a pulling member 45 and a linkage member 46. The driving component 41 is arranged on the side of the base 10 facing away from the stage 20, and the driving direction of the driving component 41 is the first direction. One end of the pushing member 42 is connected to the driving component 41, and the other end of the pushing member 42 movably passes through the base 10 and extends to the side of the second push block 32 facing the first push block 31. Among them, the pushing member 42 can move along the first direction on the base 10 by movably passing through the base 10. The linkage component 43 is slidably arranged on the side of the base 10 facing the stage 20 and is arranged adjacent to the first push block 31. The linkage component 43 is located between the first push block 31 and the third push block 33, and it can also be understood that the linkage component 43 is located between the first push block 31 and the fourth push block 34. One end of the linkage component 43 is respectively connected to the third push block 33 and the fourth push block 34. The tension spring 44 is connected between the base 10 and the other end of the linkage component 43. The compression and extension directions of the tension spring 44 are both along the first direction. The tension spring 44 is used to provide a pulling force for the linkage component 43 to approach the first push block 31. One end of the pulling member 45 is connected to the driving component 41, that is, the pulling member 45 and the pushing member 42 are connected to both ends of the driving component 41 along the first direction. One end of the linkage member 46 is connected to the linkage component 43, and the other end of the linkage member 46 movably passes through the base 10 and is movably connected to the other end of the pulling member 45. Among them, the linkage member 46 can move along the first direction on the base 10 by movably passing through the base 10. The driving component 41 is used to drive the pushing member 42 and the pulling member 45 to move closer to the second push block 32 along the first direction, so that the pushing member 42 pushes the second push block 32 to move away from the first push block 31 along the first direction and compresses the reset member 35 of the second push block 32, and makes the pulling member 45 pull the linkage member 46 and the linkage component 43 to move closer to the second push block 32 along the first direction and stretch the tension spring 44 by the linkage component 43, so that the linkage component 43 drives the third push block 33 and the fourth push block 34 to move away from each other along the second direction.

[0093] In this way, the driving component 41 drives the pushing member 42 to move away from the first pushing block 31 along the first direction, so that the pushing member 42 pushes the second pushing block 32 to move away from the first pushing block 31 along the first direction and compresses the reset member 35. The driving component 41 drives the pulling member 45 to move away from the first pushing block 31 along the first direction, so that the pulling member 45 drives the linkage component 43 to move away from the first pushing block 31 along the first direction. The linkage component 43 then drives the third pushing block 33 and the fourth pushing block 34 to move away from each other along the second direction and stretch the tension spring 44, thereby driving the second pushing block 32 to move away from the first pushing block 31, and driving the third pushing block 33 and the fourth pushing block 34 to move away from each other. When the driving component 41 removes the driving force, the second push block 32 moves along the first direction close to the first push block 31 under the elastic force of the reset member 35, and the linkage component 43 moves along the first direction close to the first push block 31 under the tension of the tension spring 44 and drives the third push block 33 and the fourth push block 34 to move close to each other, thereby driving the third push block 33 and the fourth push block 34 to move close to each other. In addition, the third push block 33 and the fourth push block 34 are clamped and centered to position the workpiece through the tension spring 44, which can meet the centering and force requirements of the workpiece.

[0094] It is understandable that in other embodiments, the driving mechanism 40 may also be composed of, for example, three cylinders, which are respectively connected to the second push block 32, the third push block 33 and the fourth push block 34, and respectively drive the second push block 32, the third push block 33 and the fourth push block 34 to move. Alternatively, the driving mechanism 40 may also be composed of two cylinder assemblies, one of which is connected to the second push block 32 and is used to drive the second push block 32 to move, and the other is respectively connected to the third push block 33 and the fourth push block 34 and is used to drive the third push block 33 and the fourth push block 34 to move closer to or away from each other. This embodiment of the present application does not specifically limit this.

[0095] In this embodiment, the driving assembly 41 includes a driving member 411 and a driving plate 412. The driving member 411 is arranged on the side of the base 10 away from the carrier 20. The driving member 411 can be a cylinder. The driving plate 412 is connected to the output end of the driving member 411 and is located on the side of the driving member 411 away from the base 10. The driving plate 412 extends toward the opposite sides of the driving member 411 along the first direction relative to the driving member 411, wherein the push member 42 is connected to one end of the driving plate 412, and the pull member 45 is connected to the other end of the driving plate 412. In this way, by setting the specific structure of the driving assembly 41, the structure of the driving assembly 41 is simple, and the driving push member 42 and the pull member 45 are driven to move synchronously.

[0096] In this embodiment, the linkage assembly 43 includes a linkage block 431, a first connecting rod 432, and a second connecting rod 433. The linkage block 431 is slidably disposed on the side of the base 10 facing the stage 20. One end of the first connecting rod 432 is rotatably connected to the linkage block 431, and the other end of the first connecting rod 432 is rotatably connected to the third pushing block 33. One end of the second connecting rod 433 is rotatably connected to the linkage block 431, and the other end of the second connecting rod 433 is rotatably connected to the fourth pushing block 34. The first connecting rod 432 and the second connecting rod 433 are symmetrically arranged with respect to the first direction. The tension spring 44 is connected between the linkage block 431 and the base 10. Thus, by setting the specific structure of the above-mentioned linkage assembly 43, when the linkage block 431 moves away from the first pushing block 31 driven by the linkage member 46, the linkage block 431 drives the first connecting rod 432 and the second connecting rod 433 to move respectively. The first connecting rod 432 and the second connecting rod 433 drive the third pushing block 33 and the fourth pushing block 34 to move away from each other in the second direction respectively. When the driving component 41 removes the driving force, the linkage block 431 moves close to the first pushing block 31 under the pulling force of the tension spring 44. The linkage block 431 drives the first connecting rod 432 and the second connecting rod 433 to move respectively. The first connecting rod 432 and the second connecting rod 433 drive the third pushing block 33 and the fourth pushing block 34 to move close to each other in the second direction respectively.

[0097] It can be understood that in other embodiments, the linkage block 431 can also be connected to the third pushing block 33 and the fourth pushing block 34 by inclined surface mating respectively. The linkage block 431 drives the third pushing block 33 and the fourth pushing block 34 to move away from each other through the abutting connection of the inclined surface mating. Springs can be arranged between the third pushing block 33 and the base 10 and between the fourth pushing block 34 and the base 10 respectively to ensure that the third pushing block 33 and the fourth pushing block 34 can move close to each other under the elastic force of their respective springs.

[0098] In this embodiment, the abutting and pulling member 45 includes an abutting and pulling body 451 and an abutting and pulling portion 452. Both the abutting and pulling body 451 and the abutting and pulling portion 452 are cylindrical. One end of the abutting and pulling body 451 is connected to the driving plate 412 of the driving component 41. The other end of the abutting and pulling body 451 movably passes through the linkage member 46. The abutting and pulling portion 452 is connected to the other end of the abutting and pulling body 451, and the cross-sectional dimension of the abutting and pulling portion 452 is larger than that of the abutting and pulling body 451. Thus, by setting the specific structure of the above-mentioned abutting and pulling member 45, when the driving component 41 drives the abutting and pulling member 45 to move away from the first pushing block 31, the abutting and pulling member 45 drives the linkage member 46 to move by abutting against the linkage member 46 through the abutting and pulling portion 452.

[0099] In this embodiment, the linkage member 46 includes a linkage body 461 and a linkage portion 462. The linkage member 46 is generally U-shaped. The number of linkage bodies 461 is two. The two linkage bodies 461 are arranged at intervals and both movably pass through the base 10 to be connected to the linkage block 431 of the linkage assembly 43. The linkage portion 462 is connected to one end of the two linkage bodies 461 facing away from the linkage block 431. A linkage hole 463 adapted to the tensioning body 451 is formed at one end of the linkage portion 462 facing away from the linkage body 461. The aperture of the linkage hole 463 is larger than the diameter of the tensioning body 451 and smaller than the diameter of the tensioning portion 452. Thus, by setting the specific structure of the above-mentioned linkage member 46, the linkage member 46 can movably pass through the base 10, and the linkage member 46 can be movably connected to the tensioning member 45, and it is easy to assemble the tensioning member 45 and the linkage member 46.

[0100] In this embodiment, the positioning mechanism 30 further includes a thrust pin 36. The thrust pin 36 is arranged on one side of the second push block 32 along the second direction and is oppositely arranged with the other end of the thrust member 42. Thus, by setting the above-mentioned thrust pin 36, the thrust member 42 can push the second push block 32 to move through the thrust pin 36. Wherein, the number of the thrust member 42 and the thrust pin 36 can both be two. The two thrust pins 36 are respectively arranged on the opposite sides of the second push block 32 along the second direction. The two thrust members 42 are both connected to the driving assembly 41 and respectively correspond to the two thrust pins 36 one by one. By setting two thrust members 42 and two thrust pins 36, the balance and stability of the second push block 32 can be ensured when the thrust member 42 pushes the second push block 32 to move.

The driving member 411 of the driving assembly 41 is disposed on the side of the bottom plate 11 away from the carrier 20. The first stopper 14 is disposed on the first side plate 12. A tension spring 44 is connected between the first stopper 14 and the linkage block 431 of the linkage assembly 43. The first stopper 14 is generally L-shaped, and the number of the tension springs 44 can be two. The second stopper 15 is disposed on the second side plate 13. A reset member 35 is connected between the second stopper 15 and the second pusher 32, and the number of the reset members 35 can be two. Wherein, a first avoidance groove 121 is formed on the first side plate 12 for avoiding the tension spring 44, and a second avoidance groove 131 is formed on the second side plate 13 for avoiding the reset member 35. Thus, by providing the specific structure of the base 10 as described above, the installation of the carrier 20, the positioning mechanism 30 and the driving mechanism 40 is realized. In addition, by providing the first side plate 12 and the second side plate 13, space is reserved for arranging structures such as the linkage assembly 43 between the bottom plate 11 and the carrier 20, so that the structure of the positioning device 100 is compact and has strong stability.

[0105] In this embodiment, the rotating mechanism 60 includes a base 61, a power source 62, a base plate 63, a first support plate 64 and a second support plate 65. The base 61 is generally a frame structure. The base 61 is arranged on the side of the base 10 away from the carrier 20. The power source 62 is arranged on the base 61.
