[0027] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0028] See also Figure 1The embodiment of the present application provides a positioning device 100 for positioning a workpiece 300 . The workpiece 300 may be a housing of an electronic product such as a mobile phone or a tablet. The positioning device 100 includes a support frame 10 , a positioning mechanism 20 and a rotating drive member 30 .

[0029] Specifically, see Figure 1 , Figure 2 and Figure 3 The positioning mechanism 20 includes a bearing member 21, a clamping drive member 22, an active positioning assembly 23, a plurality of driven positioning assemblies 24 and a plurality of fixed positioning members 25. The bearing member 21 is rotatably connected to the support frame 10 and is provided with a bearing surface 211 for carrying the workpiece 300. The bearing member 21 may be a plate-like structure, and the bearing member 21 may provide a better support for the workpiece 300. In order to make the bearing member 21 have better stability when rotating on the support frame 10, any two opposite sides of the bearing member 21 are rotatably connected to the support frame 10. The clamping drive member 22 is connected to the side of the bearing member 21 away from the bearing surface 211, and the clamping drive member 22 may be a telescopic cylinder, a telescopic motor, etc. One end of the active positioning assembly 23 is connected to the output end of the clamping drive member 22, and the other end of the active positioning assembly 23 is movably arranged on the bearing surface 211. The clamping drive member 22 is used to drive the active positioning assembly 23 to move, and one end of the plurality of driven positioning assemblies 24 are all connected to the active positioning assembly 23, and the other end is all movably arranged on the bearing surface 211. Multiple fixed positioning members 25 are all arranged on the bearing surface 211, and the clamping driving member 22 is used to drive the active positioning component 23 to move so as to drive the multiple driven positioning components 24 to move synchronously, so as to push the workpiece 300 on the bearing surface 211 to the fixed positioning member 25, so that the active positioning component 23 and the multiple driven positioning components 24 cooperate with the fixed positioning member 25 to position the workpiece 300. The fixed positioning member 25 can be a block structure, and a groove-shaped structure can be provided on one side of the fixed positioning member 25 for abutting against the workpiece 300 to improve the stability when positioning the workpiece 300.

[0030] The rotary drive member 30 is connected to the support frame 10, and the output end of the rotary drive member 30 is connected to the carrier 21, and is used to drive the carrier 21 to rotate, so as to rotate and position the part to be inspected of the workpiece 300 to be opposite to the external device. The part to be inspected of the workpiece 300 can be a side hole 310 of the workpiece 300, and the external device can be the detection device 200 described below (see Figure 7 The rotary drive member 30 may be a rotary cylinder, a stepping motor, etc., and a coupling may be connected between the rotary drive member 30 and the bearing member 21 to eliminate the rotation center offset error.

[0031] The positioning device 100 provided in the embodiment of the present application can carry the workpiece 300 through the bearing surface 211 of the bearing member 21, and can fix the workpiece 300 on the bearing surface 211 through the cooperation of the active positioning component 23, multiple driven positioning components 24 and multiple fixed positioning components 25, and can position the workpiece 300. Multiple driven positioning components 24 are connected to the active positioning component 23, and the active positioning component 23 is connected to the clamping drive 22, so the active positioning component 23 and the multiple driven positioning components 24 can be synchronously driven to move through the clamping drive 22, and the clamping and positioning of the workpiece 300 can be achieved through a single power. The bearing member 21 is also rotatably connected to the support frame 10, and is connected to the output end of the rotating drive 30. The rotating drive 30 can drive the bearing member 21 to rotate in the support frame 10, so as to rotate different sides of the workpiece 300 to the detection position, so as to facilitate the detection of the workpiece 300.

[0032] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the active positioning assembly 23 includes a connection block 231, a first power arm 232 and a first movable positioning member 233. The connection block 231 is connected to the output end of the clamping drive member 22, and the first power arm 232 is slidably connected to the bearing member 21. One end of the first power arm 232 is connected to the connection block 231, and the other end of the first power arm 232 is connected to the first movable positioning member 233. The first movable positioning member 233 extends out of the bearing surface 211 in a direction perpendicular to the bearing surface 211, and is used to cooperate with the fixed positioning member 25 to position the workpiece 300 on the bearing surface 211. The connection block 231 can be a block structure, and the first power arm 232 can be a plate structure. The first power arm 232 is convenient for being fixedly connected to the connection block 231 and the driven positioning assembly 24. In this way, the clamping driving member 22 drives the connecting block 231 to move, which can drive the first power arm 232 to move, and the first power arm 232 further drives the first movable positioning member 233 to move toward the workpiece 300 on the bearing surface 211, so that the first movable positioning member 233 abuts against the workpiece 300. At the same time, the first power arm 232 drives the driven positioning assembly 24 to move, so that the driven positioning assembly 24 and the first power arm 232 move synchronously to cooperate with the first movable positioning member 233 and the fixed positioning member 25 to clamp the workpiece 300.

[0033] See also Figure 1 , Figure 4 and Figure 5In some embodiments, the output end of the clamping driving member 22 is connected with a push member 221, and the push member 221 is slidably connected with the connecting block 231. A first elastic member 222 is sleeved on the outer side of the push member 221, and the first elastic member 222 elastically resists the push member 221 and the connecting block 231. The push member 221 can be a columnar structure, and both ends of the push member 221 can be provided with limiting protrusions 2211, which are respectively placed on both sides of the connecting block 231 to limit the push member 221. A sliding hole 2311 adapted to the push member 221 is opened on the connecting block 231, and the push member 221 is inserted into the sliding hole 2311 and can slide along the sliding hole 2311. The first elastic member 222 can be a spring, etc. It can be understood that the first elastic member 222 is sleeved on the push member 221, one end of the first elastic member 222 abuts against the limiting protrusion 2211 of the push member 221 away from the connecting block 231, and the other end of the first elastic member 222 abuts against the connecting block 231.

[0034] When the clamping driving member 22 drives the push member 221 to move away from the clamping driving member 22, the push member 221 pushes the first elastic member 222 and drives the connection block 231 to move away from the clamping driving member 22. At this time, the connection block 231 drives the first power arm 232 to move, and the first power arm 232 drives the first movable positioning member 233 to move toward the workpiece 300 to clamp the workpiece 300. When the first movable positioning member 233 abuts against the workpiece 300, the first power arm 232 stops moving, and the first elastic member 222 can be compressed by the push member 221 to play a buffering role, thereby preventing the first power arm 232 from driving the first movable positioning member 233 to rigidly contact the workpiece 300, thereby damaging the workpiece 300. When the clamping driving member 22 drives the pushing member 221 to move closer to the clamping driving member 22, the limiting protrusion 2211 of the pushing member 221 away from one end of the clamping driving member 22 abuts against the connecting block 231, thereby driving the connecting block 231 to move toward the clamping driving member 22, and the connecting block 231 drives the first power arm 232 to move, and the first power arm 232 drives the first movable positioning member 233 away from the workpiece 300 to release the workpiece 300.

[0035] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the active positioning assembly 23 further includes a positioning pin 234 and a second elastic member 235. The first movable positioning member 233 is movably connected to the first power arm 232 via the positioning pin 234. The second elastic member 235 is sleeved on the positioning pin 234 and is used to elastically abut against the first movable positioning member 233. The second elastic member 235 can be a spring, etc. It can be understood that when the first movable positioning member 233 moves with the first power arm 232 to abut against the workpiece 300, the second elastic member 235 can play a buffering role to prevent the first movable positioning member 233 from rigidly contacting the workpiece 300.

[0036] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, each driven positioning assembly 24 includes a second power arm 241, a third power arm 242 and a second movable positioning member 243. The second power arm 241 is slidably connected to the bearing member 21. The third power arm 242 is movably connected to the first power arm 232 and the second power arm 241, respectively, so that the second power arm 241 and the first power arm 232 move synchronously. The second movable positioning member 243 is connected to an end of the second power arm 241 away from the third power arm 242, and extends out of the bearing surface 211 in a direction perpendicular to the bearing surface 211, and is used to cooperate with the fixed positioning member 25 and the first movable positioning member 233 to position the workpiece 300 on the bearing surface 211. The second power arm 241 and the third power arm 242 can both be rod-shaped structures. The extension direction of the second power arm 241 can be perpendicular to the extension direction of the first power arm 232, or be set at other angles, so that the second power arm 241 drives the second movable positioning member 243 to move to stably clamp the workpiece 300. The extension direction of the third power arm 242 is at an acute angle to the extension direction of the first power arm 232 and the extension direction of the second power arm 241, so that when the first power arm 232 drives the second power arm 241 to move through the third power arm 242, there will be no jamming. It can be understood that the third power arm 242 is rotatably connected to the first power arm 232 and the second power arm 241.

[0037] See also Figure 4 In some embodiments, the positioning mechanism 20 further includes a plurality of slide rails 26 connected to the side of the bearing member 21 away from the bearing surface 211, and the plurality of slide rails 26 are respectively slidably connected to the first power arm 232 and the second power arm 241, and are used to limit the movement trajectory of the first power arm 232 and the second power arm 241. In this way, the sliding of the first power arm 232 and the second power arm 241 can be facilitated, and the movement trajectory of the first power arm 232 and the second power arm 241 can also be limited.

[0038] See also Figure 1 , Figure 2 and Figure 3In some embodiments, the positioning device 100 further includes a plurality of adsorption components 40, which are all disposed on the carrier 21, and the adsorption end of each adsorption component 40 is disposed on the carrier surface 211, for adsorbing the workpiece 300 on the carrier 21. The adsorption component 40 may be a suction cup, etc., and is connected to an exhaust device (not shown), and the adsorption end may be a suction nozzle of the suction cup. When the workpiece 300 is placed on the carrier surface 211 and is positioned with the cooperation of the active positioning component 23, the plurality of driven positioning components 24, and the plurality of fixed positioning components 25, the adsorption component 40 adsorbs the workpiece 300 to improve the stability of the workpiece 300 on the carrier 21 when the rotary drive component 30 rotates the carrier 21.

[0039] See also Figure 1 and Figure 6 In some embodiments, a stopper 11 is provided on the support frame 10, and the stopper 11 is connected to the bottom of the support frame 10 and is used to stop the carrier 21. By providing the stopper 11, when the rotation driving member 30 drives the carrier 21 to rotate to the position of the stopper 11, the carrier 21 can be stopped, so as to limit the position of the workpiece 300 after being rotated. It can be understood that two stoppers 11 can be provided, so as to stop the carrier 21 when the carrier 21 rotates clockwise or counterclockwise.

[0040] See also Figure 1 and Figure 6 In some embodiments, a shock absorbing member 12 is provided on one side of the stopper 11 for abutting against the carrier 21. The shock absorbing member 12 can be rubber or the like. By providing the shock absorbing member 12, when the carrier 21 rotates to abut against the stopper 11, the carrier 21 can be buffered to avoid rigid contact between the carrier 21 and the stopper 11.

[0041] The working process of the positioning device 100 provided in the embodiment of the present application is roughly as follows:

[0042] First, the clamping driving member 22 drives the connecting block 231 to move close to the clamping driving member 22, so that the connecting block 231 drives the first power arm 232 to move, and the first power arm 232 drives the first movable positioning member 233 to move away from the supporting member 21. At the same time, the first power arm 232 drives the second power arm 241 to move through the third power arm 242, so that the second movable positioning member 243 moves away from the supporting member 21.

[0043] Then, the workpiece 300 is placed on the bearing surface 211 of the bearing member 21, and one side of the workpiece 300 is pressed against the fixed positioning member 25. The clamping driving member 22 is started, and the clamping driving member 22 drives the connecting block 231 to move away from the clamping driving member 22, and the connecting block 231 drives the first power arm 232 to move, and the first power arm 232 drives the first movable positioning member 233 to move toward the workpiece 300. At the same time, the first power arm 232 drives the second power arm 241 to move through the third power arm 242, so that the second power arm 241 drives the second movable positioning member 243 to move toward the workpiece 300, until the first movable positioning member 233 and the second movable positioning member 243 cooperate with the fixed positioning member 25 to clamp the workpiece 300. Then, the adsorption assembly 40 is started to adsorb the workpiece 300.

[0044] After the workpiece 300 is fixed, the rotary driving member 30 is started, and the rotary driving member 30 drives the carrier 21 to rotate on the support frame 10 until the carrier 21 abuts against the stop member, so as to rotate the to-be-detected position of the workpiece 300 to the to-be-detected position.

[0045] The embodiment of the present application also provides a detection device 1000, comprising: the positioning device 100 described above; a detection device 200, comprising a detection probe 210, the detection probe 210 being used to detect a workpiece 300 fixed by the positioning device 100. During detection, the detection probe 210 is inserted into the hole to be detected of the workpiece 300, and then the data is measured, and then compared with the standard data, so as to detect whether the workpiece 300 is qualified.

[0046] See also Figure 7 The detection device 1000 provided in the embodiment of the present application can position the workpiece 300 through the positioning device 100, and can rotate the position to be detected of the workpiece 300 to correspond to the detection probe 210. The workpiece 300 can be detected by the detection probe 210. In this way, the probability of causing scratches to the workpiece 300 when detecting the workpiece 300 can be reduced, and the corresponding dimensions can be measured during the detection, so as to adjust the production machine with poor dimensions.

[0047] The working process of the detection device 1000 provided in the embodiment of the present application is roughly as follows: first, the workpiece 300 is positioned by the positioning device 100, and the position to be detected of the workpiece 300 is rotated to correspond to the position of the detection probe 210. The position to be detected of the workpiece 300 may be a side hole 310, etc. Then, the detection probe 210 is inserted into the side hole 310 of the workpiece 300, and its size is measured. After the measurement, the data is obtained, and then the data is compared with the standard value. If it is unqualified, the machine for processing the workpiece 300 can be adjusted according to the measured data to improve production efficiency.
