[0061] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] See also Figure 1 The embodiment of the present application provides a positioning device 100, which is used to position a workpiece 200. The positioning device 100 includes a bearing assembly 10 and a positioning assembly 20. The workpiece 200 may be a mobile phone mid-plate.

[0063] Understandably, Figure 1 A three-dimensional coordinate system is established in the first direction. Figure 1 The X-axis direction shown is the sliding direction of the sliding member 21 described below, and the second direction is Figure 1 The Y-axis direction shown is the movement direction of the positioning member 24 described below, and the third direction is Figure 1 The Z-axis direction shown is the direction in which the cover member 40 described below points to the supporting assembly 10 .

[0064] See also Figure 1 and Figure 2 , a carrying station 11 for carrying a workpiece 200 is provided on one side of the carrying assembly 10. The positioning assembly 20 includes a sliding member 21, a pushing member 22, a first elastic member 23, two positioning members 24 and two linkage members 25. The sliding member 21 is located on a side of the carrying assembly 10 away from the carrying station 11 and is slidably connected to the carrying assembly 10, the pushing member 22 is rotatably connected to the carrying assembly 10 and abuts against the sliding member 21, and the pushing member 22 is used to push the sliding member 21 to slide along the first direction. The first elastic member 23 and the push member 22 are respectively located on both sides of the sliding member 21 along the first direction, and the two ends of the first elastic member 23 elastically resist the sliding member 21 and the supporting component 10 respectively. The two positioning members 24 are respectively arranged on both sides of the sliding member 21 along the second direction perpendicular to the first direction and are both slidably connected to the supporting component 10. The two linkage members 25 are respectively rotatably connected to the sliding member 21 and the corresponding positioning members 24. The two linkage members 25 are used to drive the two positioning members 24 to move toward each other under the drive of the sliding member 21 to position the workpiece 200 located at the supporting station 11, or drive the two positioning members 24 to move away from each other to loosen the workpiece 200 located at the supporting station 11.

[0065] In the above-mentioned positioning device 100, the push member 22 rotates at different angles according to different types of workpieces 200, so that the push sliding member 21 can move different distances along the first direction and compress the first elastic member 23 to the supporting component 10, and then the sliding member 21 drives the two linkage members 25 to drive the two positioning members 24 to clamp and position different types of workpieces 200 along the second direction, so that the positioning device 100 is suitable for positioning different types of workpieces 200, thereby improving the versatility of the positioning device 100. In addition, the supporting component 10 and the positioning component 20 have a simple structure and a reasonable layout, and there is no need to use complex driving components, thereby simplifying the mechanical structure of the positioning device 100.

[0066] See also Figure 2 and Figure 3 In some embodiments, the bearing assembly 10 includes a bearing member 12, a base 13, a mounting member 14 and a fixing member 15. A bearing station 11 is provided on one side of the bearing member 12, and the base 13 is connected to the side of the bearing member 12 away from the bearing station 11 and forms a receiving groove 121 for receiving part of the positioning assembly 20 with the bearing member 12. The mounting member 14 is located in the receiving groove 121 and is provided with a mounting groove 141 for receiving the push member 22. The fixing member 15 is arranged opposite to the mounting member 14 along the first direction and abuts against the first elastic member 23 with the sliding member 21. The sliding member 21 and the two positioning members 24 are respectively connected to the bearing member 12 in a sliding manner, and the two sides of the push member 22 are respectively connected to the mounting member 14 and the bearing member 12 in a rotating manner.

[0067] In this way, by storing the positioning assembly 20 in the storage groove 121 , the supporting assembly 10 can reasonably utilize the working space of the supporting member 12 , so that the structural hierarchy of the supporting assembly 10 is clear, which is conducive to the reasonable arrangement of the positioning assembly 20 .

[0068] See also Figure 2 In some embodiments, the positioning member 24 includes a connecting portion 241, a movable portion 242 and a flexible positioning portion 243. The connecting portion 241 is slidably connected to the carrier 12 and is rotatably connected to the corresponding linkage member 25. The movable portion 242 can be movably arranged in the carrier 12 and connected to an end of the connecting portion 241 away from the linkage member 25. The movable portion 242 is used to move along the second direction under the drive of the connecting portion 241. The flexible positioning portion 243 is arranged on a side of the movable portion 242 facing the carrier station 11. The flexible positioning portion 243 is used to move toward the carrier station 11 under the drive of the movable portion 242 to flexibly position the workpiece 200 to the carrier station 11. Exemplarily, the material of the flexible positioning portion 243 can be urethane foam.

[0069] In this way, when the flexible positioning portion 243 moves toward the supporting workpiece 200 driven by the movable portion 242, the flexible positioning portion 243 can be in flexibly contact with the workpiece 200 placed on the supporting station 11, thereby preventing the flexible positioning portion 243 from applying excessive pressure to the workpiece 200 and damaging the workpiece 200, thereby enabling the flexible positioning portion 243 to flexibly position the workpiece 200 to the supporting station 11, which is beneficial to improving the quality of the workpiece 200.

[0070] Please continue reading Figure 2 and Figure 3 In some embodiments, the bearing assembly 10 further includes two magnetic members 16, both of which are located at the notch of the mounting groove 141 away from the sliding member 21 and are respectively embedded in the two opposite groove walls of the mounting groove 141. The push member 22 includes an eccentric cam 221, a handle 222 and two magnetic adapters 223. The eccentric cam 221 is disposed in the mounting groove 141 and is rotatably connected to the bearing member 12 and the mounting member 14 respectively, and the eccentric cam 221 abuts against the sliding member 21. The handle 222 is connected to one end of the eccentric cam 221 away from the sliding member 21. The handle 222 can drive the eccentric cam 221 to rotate under the action of an external force, so that the eccentric cam 221 pushes the sliding member 21 to move in the first direction. The two magnetic adapters 223 are respectively embedded on both sides of the handle 222, and the two magnetic adapters 223 are respectively used to magnetically absorb the corresponding magnetic members 16 to limit the handle 222. Exemplarily, the magnetic member 16 and the magnetic adapter 223 can be magnets with opposite magnetic properties.

[0071] In this way, by providing the handle 222, the operating area of ​​the push member 22 can be increased, so that the operator can stably drive the handle 222 to drive the eccentric cam 221 to rotate, thereby improving the push stability of the push member 22. In addition, when the handle 222 rotates by a preset angle in a preset direction or by a preset angle in a direction opposite to the preset direction, the magnetic adapter 223 and the corresponding magnetic member 16 are magnetically attracted to each other to limit the position of the handle 222 and the eccentric cam 221, thereby preventing the positioning member 24 from resetting during the process of positioning the workpiece 200 or loosening the workpiece 200, thereby improving the positioning stability of the positioning assembly 20.

[0072] See also Figure 1 and Figure 3 In some embodiments, the carrier assembly 10 further includes a reference member 17, which is disposed on the carrier 12 adjacent to the carrier station 11. The positioning device 100 further includes a pushing assembly 30, which is disposed on both sides of the carrier station 11 along the first direction along with the reference member 17, and the pushing assembly 30 is used to move along the first direction close to the reference member 17 to position the workpiece 200 to the carrier station 11 along the first direction.

[0073] In this way, the pushing component 30 moves along the first direction close to the reference, so that the pushing component 30 can position the workpiece 200 to the carrying station 11 along the first direction, and then the positioning device 100 simultaneously positions the workpiece 200 in the first direction and the positioning direction, thereby improving the positioning stability of the positioning device 100.

[0074] In some embodiments, the pushing assembly 30 includes a connecting member 31, a pushing member 32, a second elastic member 33 and a guide member 34. The connecting member 31 is disposed on the carrier 12 along the first direction relative to the reference member 17 and is provided with a receiving groove 311. One end of the pushing member 32 is movably inserted into the receiving groove 311, and the second elastic member 33 is received in the receiving groove 311 and elastically resists the connecting member 31 and the pushing member 32 respectively. The second elastic member 33 is used to drive the pushing member 32 to approach the reference member 17 along the first direction, so that the other end of the pushing member 32 positions the workpiece 200 to the reference member 17 along the first direction. The guide member 34 is inserted through the pushing member 32 and the second elastic member 33 and is connected to the connecting member 31. The guide member 34 is used to guide the pushing member 32 to move in the direction of the connecting member 31 pointing to the reference member 17.

[0075] In this way, the second elastic member 33 provides elastic force and drives the push member 32 to move along the first direction, so that the push member 32 can stably position the workpiece 200 to the reference member 17 along the first direction, and the connection structure between the push member 32 and the second elastic member 33 is simple, which simplifies the mechanical structure of the push assembly 30 and the positioning device 100. In addition, the guide member 34 can be movably arranged on the push member 32, so that the guide member 34 can guide the movement direction of the push member 32, so that the push member 32 always moves along the first direction toward the reference member 17, thereby improving the positioning accuracy of the push member 32.

[0076] Please continue reading Figure 4 In some embodiments, a connecting member 31 is provided with a locking groove 312 and an operating groove 313 on one side away from the bearing member 12, and the locking groove 312 and the operating groove 313 are respectively arranged along the second direction and the first direction and are both connected to the receiving groove 311. The pushing assembly 30 further includes a locking member 35, one end of which is connected to the pushing member 32, and the other end of which can be moved into the locking groove 312 or into the operating groove 313 under the action of an external force to lock the pushing member 32 or loosen the pushing member 32.

[0077] In this way, when the positioning device 100 receives the workpiece 200, the locking member 35 moves into the locking groove 312 under the action of external force, so that the pushing member 32 moves away from the reference member 17 under the action of the locking member 35 and compresses the second elastic member 33 to the bottom of the accommodating groove 311, so that there is a certain activity space between the pushing member 32 and the reference member 17, which is convenient for the workpiece 200 to be positioned to be stably placed on the carrying station 11; when the positioning device 100 positions the workpiece 200, the locking member 35 moves into the working groove 313 under the action of external force, so that the locking member 35 loosens the locked pushing member 32, and then the compressed second elastic member 33 provides elastic force to drive the pushing member 32 to move close to the reference member 17, so that the pushing component 30 can quickly position the workpiece 200 along the first direction, thereby improving the positioning efficiency.

[0078] See also Figure 1 and Figure 4 In some embodiments, the pushing member 32 includes a pushing portion 321 and a pressing portion 322. The pushing portion 321 abuts against the second elastic member 33 and is sleeved on the guide member 34. The pushing portion 321 is used to push the workpiece 200. The pressing portion 322 is disposed on a side of the pushing portion 321 away from the carrier 12. The positioning device 100 also includes a covering member 40. The covering member 40 is movably disposed above the carrier 12. The covering member 40 is used to cover the workpiece 200 located at the carrier station 11 and press the workpiece 200 to the carrier 12 along the third direction under the pushing of the pressing portion 322. The first direction, the second direction and the third direction are perpendicular to each other.

[0079] In this way, the cover member 40 is covered on the workpiece 200 at the supporting station 11, and the cover member 40 is pushed to press the workpiece 200 to the supporting member 12 by the pressing portion 322, so that the positioning device 100 can position the workpiece 200 along the third direction, further improving the positioning stability of the positioning device 100.

[0080] See also Figure 1 In some embodiments, the cover member 40 is provided with a avoiding groove 41, and the avoiding groove 41 penetrates the cover member 40 along the third direction.

[0081] Thus, by providing the avoidance groove 41 , the avoidance groove 41 can avoid the external equipment, so that the external equipment can perform processing operations on the positioned workpiece 200 and prevent interference between the cover 40 and the external equipment.

[0082] In some embodiments, the support assembly 10 further includes two handles 18 , which are disposed on opposite sides of the support member 12 . The two handles 18 can drive the support member 12 and the positioned workpiece 200 to move synchronously under the action of external force.

[0083] In this way, the handle 18 drives the carrier 12 and the positioned workpiece 200 to move synchronously under the action of external force, so that the workpiece 200 can be transferred between multiple external devices without using a robot or other complex transfer mechanism to drive the positioning device 100 to move, thereby simplifying the mechanical structure of the positioning device 100 and reducing the cost of use.

[0084] The working process of the positioning device 100 is roughly as follows:

[0085] First, the push member 22 rotates by a preset angle in a direction opposite to the preset direction under the action of an external force to cancel the push of the sliding member 21. At this time, the sliding member 21 cancels the compression of the first elastic member 23 to the fixing member 15, so that the compressed first elastic member 23 provides elastic force and drives the sliding member 21 to move away from the fixing member 15, so that the two linkage members 25 drive the two positioning members 24 to move in opposite directions under the drive of the sliding member 21, and the locking member 35 moves into the locking groove 312 under the action of an external force, so that the pushing member 32 moves away from the reference member 17 under the drive of the locking member 35 and compresses the second elastic member 33 to the bottom of the accommodating groove 311, and then the workpiece 200 is placed on the carrying station 11 of the carrying member 12;

[0086] Then, the push member 22 rotates by a preset angle in a preset direction according to the type of the workpiece 200 under the action of an external force to push the sliding member 21 to slide in the first direction, so that the two linkage members 25 drive the two positioning members 24 to move toward each other under the drive of the sliding member 21, so that the two positioning members 24 flexibly position the workpiece 200 in the second direction, so that the positioning device 100 is suitable for positioning different types of workpieces 200, thereby improving the versatility of the positioning device 100;

[0087] Finally, the cover member 40 is covered on the top of the workpiece 200. Then, the locking member 35 is moved into the working groove 313 under the action of external force, so that the pushing member 32 moves close to the reference member 17 under the drive of the compressed second elastic member 33, so that the pushing part 321 and the reference member 17 position the workpiece 200 along the first direction. At the same time, the cover member 40 positions the workpiece 200 along the third direction under the push of the pressure member, thereby achieving simultaneous positioning of the workpiece 200 along the first direction, the second direction, and the third direction, thereby improving the positioning stability of the positioning device 100. In addition, the supporting component 10, the positioning component 20, the pushing component 30 and the cover member 40 have a simple structure and a reasonable layout, and there is no need to use complex driving components, thereby simplifying the mechanical structure of the positioning device 100.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
