[0039] Referring to Figures 1 to 4 , a schematic structural view of a material positioning mechanism according to an embodiment of the present application is shown, which specifically may include: a profiling fixed structure 10 and a pressing structure, and the profiling fixed structure 10 is arranged adjacent to the pressing structure; wherein,

[0040] The profiling fixed structure 10 includes a bracket 11 and a profiling member 12 connected to the bracket 11, and the profiling member 12 is adapted to the material to be processed;

[0041] The pressing structure includes a base 21 and a pressing rod 22, and the pressing rod 22 is movably connected to the base 21;

[0042] When the material to be processed is placed in the profiling member 12 of the profiling fixed structure 10, the pressing rod 22 moves towards the profiling member 12 and presses on the material to be processed to press the material to be processed.

[0043] In the embodiment of the present application, by setting the profiling member 12 of the profiling fixing structure 10 to be adapted to the material to be processed, that is, the shape of the profiling member 12 is the same as the shape of the material to be processed, and the size of the profiling member 12 is the same as or close to the size of the material to be processed. Thus, the profiling member 12 has a high adaptability to the material to be processed with a special-shaped structure, such as a headphone housing, etc. Moreover, the material to be processed is placed in the profiling member 12 of the profiling fixing structure 10. When it is necessary to process the material to be processed, the pressing rod 22 of the pressing structure is made to move towards the profiling member 12 and press the material to be processed in the profiling member 12, so that the material to be processed is pressed and fixed in the profiling member 12 to achieve a good fixing effect, thereby making the material to be processed have good stability and facilitating the improvement of the stability and reliability of the processing process. It reduces the risk of easily scratching the material and causing product scrapping when using a tongue piece to fix the material to be processed, and improves the yield rate of the product.

[0044] Specifically, in the embodiment of the present application, after the processing of the material to be processed is completed, for example, after the circuit layout of the headphone housing is completed, the pressing rod 22 can move away from the profiling member 12 to release the pressing on the material, so as to prepare for the pressing and fixing of the next material to be processed. In this way, cyclic operation is carried out to process multiple materials to be processed.

[0045] In the embodiment of the present application, by way of example, taking the material to be processed as a headphone housing (also called a headphone rubber housing) as an example, the headphone housing can be used to accommodate a Bluetooth headset and charge it. Adapted to the special-shaped structure of the headphone, the accommodation groove in the headphone housing also has a similar special-shaped structure. Therefore, the profiling member 12 is set to be adapted to the headphone housing, so that the profiling fixing structure 10 has a relatively stable fixing effect on the headphone housing and avoids the headphone housing being easily scratched and damaged.

[0046] In the embodiment of the present application, the profiling fixing structure 10 is arranged adjacent to the pressing structure so that the pressing rod 22 can move towards the profiling member 12 and press on the material to be processed. By way of example, the pressing structure can be arranged on the right side of the profiling fixing structure 10, or the pressing structure can also be arranged on the left side of the profiling fixing structure 10. In addition, the pressing structure can also be arranged above the profiling fixing structure 10, and it can be set according to the actual space layout. The embodiment of the present application does not limit the specific setting position of the profiling fixing structure 10 and the pressing structure.

[0047] Specifically, in the embodiment of the present application, the bracket 11 is used to provide a relatively stable supporting effect for the profiling member 12. By way of example, the bracket 11 can be provided with an opening to facilitate the processing of the material to be processed through the opening. Moreover, the base 21 is used to provide a relatively stable supporting effect and an installation position for the pressing rod 22, so that the pressing rod 22 can move more reliably.

[0048] Optionally, in the embodiments of the present application, the material positioning mechanism further includes a first driving member 30; the first driving member 30 is connected to the base 21, and the output end of the first driving member 30 is connected to the pressing rod 22; when the material to be processed is placed in the profiling member 12 of the profiling and fixing structure 10, the first driving member 30 drives the pressing rod 22 to move towards the profiling member 12 and press on the material to be processed, or the first driving member 30 drives the pressing rod 22 to move away from the profiling member 12. In this way, the first driving member 30 provides a relatively stable and reliable driving force for the movement of the pressing rod 22, and also improves the control accuracy of the movement of the pressing rod 22. Specifically, after the material to be processed is placed in the profiling member 12 of the profiling and fixing structure 10, the first driving member 30 can drive the pressing rod 22 to move towards the profiling member 12 and press on the material to be processed to clamp the material to be processed for easy processing. After the processing of the material to be processed is completed, the first driving member 30 can drive the pressing rod 22 to move away from the profiling member 12 to prepare for the next material to be processed.

[0049] In the embodiments of the present application, for example, the first driving member 30 may include a cylindrical fixing portion and a movable portion movably connected to the fixing portion. The fixing portion is connected to the base 21 to achieve a relatively stable and reliable connection between the first driving member 30 and the base 21, and the cylindrical fixing portion may extend in a direction forming an angle with the horizontal plane; the movable portion is connected to the pressing rod 22, and the movable portion can move along the axial direction of the cylindrical fixing portion, that is, the movable portion can move in a direction forming an angle with the horizontal plane, so that the first driving member 30 can perform a telescopic movement and drive the pressing rod 22 to move. The above angle may be 10°, 15° or 18°, etc., and the embodiments of the present application may not limit the specific value of the angle.

[0050] For example, in the embodiments of the present application, the first driving member 30 may be a cylinder, which is a relatively common driving member with wide application and easy availability. In addition, the first driving member 30 may also be a hydraulic cylinder, an electric cylinder, or a linear motor, etc., and the embodiments of the present application may not limit the specific type of the first driving member 30.

[0051] Optionally, in the embodiment of the present application, the pressing rod 22 includes a pressing rod body 221 and a connecting portion 222 connected to the pressing rod body 221 at an angle. The base 21 is provided with a rotating shaft 23. One end of the pressing rod body 221 close to the connecting portion 222 is rotatably connected to the rotating shaft 23, and one end of the connecting portion 222 away from the pressing rod body 221 is rotatably connected to the output end of the first driving member 30; the output end of the first driving member 30 drives the connecting portion 222 to rotate, and the connecting portion 222 drives the pressing rod body 221 to rotate relative to the rotating shaft 23. One end of the pressing rod body 221 away from the connecting portion 222 moves towards the profiling member 12 and presses on the workpiece to be processed. In this way, through the rotational connection between the pressing rod body 221 and the rotating shaft 23, a relatively flexible rotational effect between the pressing rod 22 and the base 21 is achieved. Moreover, the pressing rod 22 includes the pressing rod body 221 and the connecting portion 222 connected at an angle, so that the movement of the pressing rod 22 can be similar to a lever action, that is, the pressing rod body 221 and the connecting portion 222 can rotate respectively with the rotating shaft 23 as the fulcrum, improving the pressing effect of the pressing rod body 221 on the workpiece to be processed. For example, a protruding pressing block may be provided at one end of the pressing rod body 221 away from the connecting portion 222, and the workpiece to be processed in the profiling member 12 is pressed by the pressing block.

[0052] For example, in the embodiment of the present application, the angle between the pressing rod body 221 and the connecting portion 222 can be any value between 60 - 150°, such as 90°, 85°, 70°, 60°, 110°, 115°, 120° or 150°, etc., which can be set according to actual needs. The specific value of the angle between the pressing rod body 221 and the connecting portion 222 in the embodiment of the present application may not be limited.

[0053] Specifically, the output end of the first driving member 30 drives the connecting portion 222 to rotate, and the connecting portion 222 drives the pressing rod body 221 to rotate relative to the rotating shaft 23, so that one end of the pressing rod body 221 away from the connecting portion 222 moves towards or away from the profiling member 12. For example, the output end of the first driving member 30 extends, driving the connecting portion 222 to rotate counterclockwise, and the connecting portion 222 drives the pressing rod body 221 to rotate counterclockwise relative to the rotating shaft 23, so that one end of the pressing rod body 221 away from the connecting portion 222 moves towards the profiling member 12 to press the workpiece to be processed in the profiling member 12. The output end of the first driving member 30 contracts, driving the connecting portion 222 to rotate clockwise, and the connecting portion 222 drives the pressing rod body 221 to rotate clockwise relative to the rotating shaft 23, so that one end of the pressing rod body 221 away from the connecting portion 222 moves away from the profiling member 12 to release the pressing on the workpiece to be processed in the profiling member 12.

[0054] Optionally, in the embodiments of the present application, the material positioning mechanism further includes a sensor 40 and a controller electrically connected to the sensor 40. The sensor 40 is used to detect whether the material to be processed is placed in the profiling part 12. The controller is electrically connected to the first driving member 30. When the sensor 40 detects that the material to be processed is placed in the profiling part 12, the sensor 40 sends a driving signal to the controller, and the controller controls the first driving member 30 to drive the pressing rod 22 to move based on the driving signal. In this way, the placement of the material to be processed can be detected by the sensor 40, and the automatic driving of the first driving member 30 can be realized through the controller. Thus, the automatic detection and automatic control of pressing the material to be processed are achieved, and the automation degree and control accuracy of the material positioning mechanism are improved.

[0055] In the embodiments of the present application, for example, the sensor 40 can be connected to the base 21 of the pressing structure. Since the pressing structure is arranged adjacent to the profiling and fixing structure 10, the sensor 40 can be arranged at a position with the same or similar height as the profiling part 12, so that the sensor 40 is arranged opposite to the profiling part 12, which is convenient for the sensor 40 to detect whether the material to be processed is placed in the profiling part 12. Moreover, it is also convenient to realize a relatively simple circuit layout among the sensor 40, the first driving member 30 connected to the base 21 and the controller. In addition, the sensor 40 can also be arranged on a separate support frame, and the specific arrangement position of the sensor 40 in the embodiments of the present application can be not limited.

[0056] For example, in the embodiments of the present application, the sensor 40 can be an infrared sensor 40, and can also be a photoelectric sensor 40, etc., which have a wide range of applications. The specific type of the sensor 40 in the embodiments of the present application can be not limited.

[0057] In the embodiments of the present application, optionally, the profiling part 12 is embedded in the bracket 11, and the sensor 40 is arranged opposite to the profiling part 12. The bracket 11 is provided with a clearance groove 13 at a position opposite to the sensor 40, so that the sensor 40 can detect whether the material to be processed is placed in the profiling part 12 through the clearance groove 13. In this way, through the clearance groove 13, the part structure of the profiling part 12 opposite to the sensor 40 is exposed outside the bracket 11, which is convenient for the detection signal sent by the sensor 40, such as an infrared light signal, etc., to directly contact the profiling part 12 more directly, and avoids problems such as interference of the detection signal sent by the sensor 40 by the bracket 11 or inaccurate detection.

[0058] Optionally, in the embodiment of the present application, the profiling member 12 includes a first profiling groove 14 and a second profiling groove 15 which are arranged at intervals, and the first profiling groove 14 and the second profiling groove 15 are adapted to the material to be processed. In this way, the adaptability of the profiling member 12 to the material to be processed is further improved. For example, the earphone shell usually has a first groove and a second groove, which correspond to the left earphone and the right earphone respectively. The profiling member 12 can be adapted to the first groove and the second groove of the earphone shell through the first profiling groove 14 and the second profiling groove 15. For example, the shape of the first profiling groove 14 can be the same as the shape of the second profiling groove 15, which is arranged in a mirror image. In addition, the shape of the first profiling groove 14 can also be different from the shape of the second profiling groove 15, and the embodiment of the present application does not limit this.

[0059] In the embodiment of the present application, optionally, the material positioning mechanism also includes a material picking structure 50, which is arranged above the profiling fixed structure 10; the material picking structure 50 includes a first profiling block 51 and a second profiling block 52 movably connected along the horizontal direction X, and the first profiling block 51 and the second profiling block 52 extend into the material to be processed and move away from each other, so that the first profiling block 51 and the second profiling block 52 abut against the material to be processed, and the material to be processed is placed on the profiling member 12. In the embodiment of the present application, the material to be processed may have a groove. When the material to be processed needs to be taken, the first profiling block 51 and the second profiling block 52 of the material taking structure 50 may be extended into the groove of the material to be processed, and the first profiling block 51 and the second profiling block 52 are moved away from each other along the horizontal direction X until the first profiling block 51 and the second profiling block 52 are respectively abutted against the groove wall of the groove of the material to be processed to open the material to be processed, so that the material taking structure 50 has a more reliable fixing effect on the material to be processed, thereby facilitating the placement of the material to be processed on the profiling member 12 and improving reliability.

[0060] Optionally, in the embodiment of the present application, the material taking structure 50 further includes a second driving member 53 and a connecting plate 54 connected to the second driving member 53; the first profiling block 51 and the second profiling block 52 are respectively connected to the connecting plate 54 in a sliding manner along the horizontal direction X, and the output end of the second driving member 53 is connected to at least one of the first profiling block 51 and the second profiling block 52; the second driving member 53 drives at least one of the first profiling block 51 and the second profiling block 52 to move so that the first profiling block 51 and the second profiling block 52 are moved away from each other. In this way, the second driving member 53 provides a more reliable power source for the movement of the second profiling block 52 and / or the second profiling block 52, and the connecting plate 54 enables the first profiling block 51 and the second profiling block 52 to move away from or towards each other more smoothly.

[0061] Exemplarily, in the embodiment of the present application, after the material taking structure 50 places the material to be processed on the profiling member 12, the second driving member 53 can drive at least one of the first profiling block 51 and the second profiling block 52 to move, so that the first profiling block 51 and the second profiling block 52 approach each other, in order to prepare for taking the next material to be processed.

[0062] In the embodiment of the present application, exemplarily, the second driving member 53 can be a cylinder, which is a relatively commonly used driving member, widely applied and easily obtained. In addition, the second driving member 53 can also be a hydraulic cylinder, an electric cylinder, a linear motor, etc. The embodiment of the present application can not limit the specific type of the second driving member 53.

[0063] Optionally, in the embodiment of the present application, the material positioning mechanism further includes a buffer member 60. The buffer member 60 is elastically connected to the second driving member 53 along the vertical direction Y to buffer the movement of the material taking structure 50. In this way, when the material taking structure 50 moves along the vertical direction Y, the buffer member 60 can provide a buffer force for the material taking structure 50 to avoid hard collisions between the material taking structure 50 and other connecting plates 54 or fixing blocks and other structures, and extend the service life of the material positioning mechanism. Exemplarily, the buffer member 60 can be a structure provided with a spring, silica gel, rubber, etc., which has elasticity and can provide a good buffer effect. The embodiment of the present application can not limit the specific type of the buffer member 60.

[0064] In the embodiment of the present application, optionally, the material positioning mechanism further includes a substrate 70, a lifting structure 80 and a rotating structure 90; the lifting structure 80 is slidably connected to the substrate 70 along the vertical direction Y, the rotating structure 90 is rotatably connected to the lifting structure 80, and the material taking structure 50 is connected to the rotating structure 90. In this way, the lifting structure 80 can make the material taking structure 50 move up and down along the vertical direction Y to adjust the height position of the material taking structure 50, and the rotating structure 90 can adjust the orientation of the material taking structure 50, so as to facilitate more accurate adjustment and control of the material taking structure 50. Specifically, the lifting structure 80 moves relative to the substrate 70 along the vertical direction Y, driving the rotating structure 90 to move, and the rotating structure 90 drives the material taking structure 50 to move in the vertical direction Y. When the material taking structure 50 needs to be rotated, the rotating structure 90 rotates relative to the lifting structure 80, driving the material taking structure 50 to rotate and adjusting the orientation of the material taking structure 50.

[0065] Exemplarily, in the embodiment of the present application, the lifting structure 80 may include a driving cylinder and a movable plate. The driving cylinder is connected to the substrate 70, and the movable plate is connected to the output piston of the driving cylinder. The output piston is movably connected to the substrate 70 in the vertical direction Y, driving the movable plate to move in the vertical direction Y. The rotating structure 90 may include a driving motor, a fixing plate, and a rotating shaft 23. The fixing plate may be connected to the movable plate of the lifting structure 80. The rotating shaft 23 is rotatably connected to the fixing plate. The driving motor is connected to the rotating shaft 23 and can drive the rotating shaft 23 to rotate. The material taking structure 50 is connected to the rotating shaft 23. The driving motor drives the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 drives the material taking structure 50 to rotate. In addition, the lifting structure 80 and the rotating structure 90 may also be of other structural types, and there are various implementation manners in the prior art. The specific types of the lifting structure 80 and the rotating structure 90 in the embodiment of the present application may not be limited.

[0066] In the embodiment of the present application, exemplarily, the complete material taking and positioning process for the to-be-processed material may be as follows: The lifting structure 80 drives the rotating structure 90 to drive the material taking structure 50 to move downward, so that the material taking structure 50 picks up a to-be-processed material, such as a headphone housing, from the tray. Specifically, the first profiling block 51 and the second profiling block 52 of the material taking structure 50 extend into the to-be-processed material and move away from each other, so that the first profiling block 51 and the second profiling block 52 abut against the inner wall of the to-be-processed material to expand it, achieving a relatively firm fixing effect on the to-be-processed material. Then, the lifting structure 80 drives the rotating structure 90 to drive the material taking structure 50 to move upward above the profiling fixing structure 10. The rotating structure 90 drives the material taking structure 50 to rotate, so that the to-be-processed material has better alignment with the profiling part 12. Then, the lifting structure 80 drives the rotating structure 90 to drive the material taking structure 50 to move downward, so that the material taking structure 50 places the to-be-processed material into the first profiling groove 14 and / or the second profiling groove 15 in the profiling part 12.

[0067] Next, the sensor 40 detects that the material to be processed is placed inside the profiling part 12 and sends a driving signal to the controller. The controller controls the first driving part 30 to drive the pressure rod 22 to move based on the driving signal. Specifically, the output end of the first driving part 30 extends to drive the connecting part 222 of the pressure rod 22 to rotate. The connecting part 222 drives the pressure rod body 221 to rotate relative to the rotating shaft 23, so that the end of the pressure rod body 221 away from the connecting part 222 moves towards the profiling part 12 and presses on the material to be processed, achieving relatively accurate and firm positioning and fixing of the material to be processed, and thus facilitating circuit layout such as electrode connection for the material to be processed. When the processing of the material is completed, the output end of the first driving part 30 contracts to drive the connecting part 222 of the pressure rod 22 to rotate. The connecting part 222 drives the pressure rod body 221 to rotate relative to the rotating shaft 23, so that the end of the pressure rod body 221 away from the connecting part 222 moves away from the profiling part 12 to reset and release the pressing on the material. Then, the processed material can be taken out by a robot or a module structure to complete the positioning and processing of the material to be processed.

[0068] In summary, the material positioning mechanism described in the embodiments of the present application has at least the following advantages:

[0069] In the embodiments of the present application, the material positioning mechanism includes: a profiling and fixing structure and a pressing structure. The profiling and fixing structure and the pressing structure are arranged adjacent to each other. Among them, the profiling and fixing structure includes a bracket and a profiling part connected to the bracket. The profiling part is adapted to the material to be processed. The pressing structure includes a base and a pressure rod. The pressure rod is movably connected to the base. When the material to be processed is placed in the profiling part of the profiling and fixing structure, the pressure rod moves towards the profiling part and presses on the material to be processed to press the material to be processed. In this way, by setting the profiling part of the profiling and fixing structure to be adapted to the material to be processed, that is, the shape of the profiling part is the same as the shape of the material to be processed, and the size of the profiling part is the same as or close to the size of the material to be processed, so that the profiling part has a high adaptability to the material to be processed with a special-shaped structure such as a headphone shell. And when the material to be processed is placed in the profiling part of the profiling and fixing structure and the material to be processed needs to be processed, the pressure rod of the pressing structure moves towards the profiling part and presses the material to be processed in the profiling part, so that the material to be processed is pressed and fixed well in the profiling part, so that the material to be processed has good stability, facilitating the improvement of the stability and reliability of the processing process. It reduces the risk of easily scratching the material and causing product scrapping when using a tongue piece to fix the material to be processed, and improves the yield rate of the product.
