[0036] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0037] It should be noted that like reference numerals and letters refer to like items throughout the several views, and thus, once an item is defined in one view, it need not be discussed further in subsequent views.

[0038] A positioning mechanism 200 according to an embodiment of the present application will now be described in detail below with reference to the accompanying drawings.

[0039] According to an embodiment of the present application, a positioning mechanism 200 is provided. As shown in Figure 2 , Figure 3 the positioning mechanism 200 includes:

[0040] a base 201, the base 201 being provided with a positioning part 2011, a middle part of the positioning part 2011 forming a positioning groove 2012, the positioning groove 2012 having a width greater than that of a workpiece to be processed; and

[0041] The moving assembly comprises a first moving part 202 and a first abutting part, the first moving part 202 is connected with the first abutting part, the first abutting part is located at one side of the positioning groove 2012, the first moving part 202 drives the first abutting part to move along the width direction of the positioning groove 2012, the first abutting part comprises a first connecting plate, an elastic member 204 and an abutting block 205, the first connecting plate is connected with the first moving part 202, the elastic member 204 is arranged on the first connecting plate, and the elastic member 204 is connected with the abutting block 205.

[0042] Specifically, as shown in Figure 2 、 Figure 3 The positioning mechanism 200 is used for positioning the component, so as to install the component at a set position of the electronic module 302 at a proper angle. The component can be but is not limited to a key 300, a battery, a microphone, a loudspeaker, a chip, etc. For the purpose of illustration, the key 300 is taken as an example below.

[0043] The base 201 is used for carrying the key 300. The base 201 is provided with a positioning part 2011. The positioning part 2011 is provided with a positioning groove 2012 in the middle part. The positioning groove 2012 is used for positioning the key 300. The transfer mechanism 102 has a clamping jaw. After the clamping jaw clamps the key 300 from the feeding mechanism 101, the key 300 is placed into the positioning groove 2012. Since the width of the positioning groove 2012 is greater than the width of the component to be processed, the operation of placing the key 300 into the positioning groove 2012 by the transfer mechanism 102 is easier.

[0044] It should be noted that if the width of the positioning groove 2012 is too small, for example, the width is equal to the width of the key 300, for example, the width of the key 300, since the accuracy of the vision module cannot meet the requirements, and the clamping jaw will block the line of sight of the vision module, it is difficult for the transfer structure to place the key 300 into the positioning groove 2012 after transferring the key 300, resulting in the failure of positioning the key 300. Therefore, in order to better position the key 300, the positioning mechanism 200 of the embodiment of the application adopts the mode of placing the key 300 first and then positioning the key 300. The width of the positioning groove 2012 of the embodiment of the application is greater than the width of the key 300, so that the operation of placing the key 300 into the positioning groove 2012 by the transfer mechanism 102 is easy. Then, the key 300 is positioned by using the moving assembly.

[0045] Optionally, the material of the base 201 is metal, ceramic, plastic, wood, etc. The base 201 and the positioning part 2011 are integrally formed, or the base 201 and the positioning part 2011 are respectively formed and then connected together.

[0046] The key 300 is positioned in a set direction in the positioning part 2011. After positioning, the key 300 is sucked by the suction nozzle 1041 of the assembling mechanism 104 and assembled on the electronic module 302. The positioning part 2011 is provided with a notch for avoiding the suction nozzle 1041 of the assembling mechanism 104. The notch can also avoid the clamping jaw of the transferring mechanism 102.

[0047] Since the positioning groove 2012 has a large width, the positioning part 2011 can easily receive the key 300 and coarsely position the key 300, but needs to ensure that the key 300 is attached to the set position of the positioning part 2011, such as the side wall of the positioning groove 2012, when the key 300 is sucked by the suction nozzle 1041. The moving assembly is used to move the key 300 in the positioning part 2011 to make the key 300 attached to the set position of the positioning part 2011. The first moving part 202 is used to move the first abutting part. The first moving part 202 can be a pneumatic cylinder, an electric cylinder, etc. The first abutting part is located at one side of the positioning groove 2012. The first moving part 202 drives the first abutting part to move along the width direction of the positioning groove 2012. The first abutting part pushes the key 300 to move to make the key 300 attached to the side wall of the positioning groove 2012.

[0048] As shown in Figure 3 The first abutting part includes a first connecting plate, an elastic member 204 and an abutting block 205. The first connecting plate is connected with the first moving part 202. For example, the two are connected by bolt connection, welding, riveting, clamping or the like. The first connecting plate is made of metal, plastic, ceramic, wood or the like. The elastic member 204 is arranged on the first connecting plate. The elastic member 204 is connected with the abutting block 205. The elastic member 204 can provide elastic force. The elastic member 204 is a spring, a spring sheet, an elastic rubber member, an elastic silica gel member or the like. The abutting block 205 is used to directly contact with the key 300. The abutting block 205 is made of metal, plastic, ceramic, rubber, silica gel, wood or the like. Under the driving of the first moving part 202, the first abutting part approaches the key 300 and abuts against the key 300. Since the elastic member 204 can be elastically deformed, the elastic member 204 can buffer the force of the first abutting part to the key 300, preventing the key 300 from being deformed or even broken due to being pressed by the first abutting part and the side wall of the positioning groove 2012.

[0049] In the embodiment of the present application, the positioning mechanism 200 adopts the mode of first placing the workpiece to be processed and then positioning the workpiece to be processed. The middle part of the positioning part 2011 is formed with the positioning groove 2012 which has a width greater than that of the workpiece to be processed, so that the workpiece to be processed is easily placed in the positioning groove 2012 and coarsely positioned. The moving assembly includes the first moving part 202 and the first abutting part. The first moving part 202 drives the first abutting part to move along the width direction of the positioning groove 2012, so as to push the workpiece to be processed to be attached to the side wall of the positioning groove 2012, and the positioning of the workpiece to be processed is accurate.

[0050] In addition, the first abutment portion includes a first connecting plate, an elastic member 204, and an abutment block 205. The first connecting plate is used to connect the first movable portion 202 to the elastic member 204. The elastic member 204 is connected to the abutment block 205. The abutment block 205 is used to directly contact the workpiece to be processed. The elastic member 204 can undergo elastic deformation, thereby buffering the force exerted by the first abutment portion on the key 300, preventing the key 300 from being deformed or even broken due to being squeezed by the first abutment portion and the side wall of the positioning groove 2012, thereby ensuring the yield of the workpiece to be processed. The positioning mechanism 200 has precise positioning and high positioning efficiency.

[0051] In a specific embodiment of the present invention, a plurality of positioning portions 2011 are provided on the base 201, the first connecting plate includes a connecting portion 2031 and a plurality of support arms 2032, the plurality of support arms 2032 are arranged in parallel, the plurality of support arms 2032 are connected to the connecting portion 2031, and the elastic member 204 and the abutment block 205 are provided on the same side of the plurality of support arms 2032.

[0052] like Figure 3 As shown, four positioning parts 2011 are provided on the base 201. The first connecting plate includes a connecting part 2031 and a plurality of supporting arms 2032.

An elastic member 204 and an abutment block 205 are provided on one side of the end of each supporting arm 2032. The four elastic members 204 and the four abutment blocks 205 are arranged in the same direction, all facing the base 201. In this way, the positioning mechanism 200 can position four workpieces to be processed at one time, thereby making the positioning efficiency of the workpieces to be processed higher.

[0053] Optionally, the connection portion 2031 and the support arms 2032 may be made of metal, plastic, ceramic, rubber, silicone, wood, or the like. Alternatively, the connection portion 2031 and the plurality of support arms 2032 may be integrally formed. Alternatively, the connection portion 2031 and the plurality of support arms 2032 may be formed separately and then assembled together.

[0056] like Figure 2-Figure 4 As shown, in this embodiment, the workpiece to be processed not only needs to be positioned along the width direction of the positioning groove 2012, but also needs to be positioned in other directions, for example, it needs to be attached to the positioning retaining wall. The extension direction of the positioning retaining wall is different from the extension direction of the side wall of the positioning groove 2012. The workpiece to be processed is positioned for the first time by the first moving part 202 and the first abutting part. The workpiece to be processed is positioned for the second time by the second moving part 206 and the second abutting part, so that the workpiece to be processed not only fits on the side wall of the positioning groove 2012 but also fits on the positioning retaining wall. By providing the second moving part 206 and the second abutting part, the workpiece to be processed can be positioned in multiple directions, further improving the positioning accuracy and processing efficiency of the workpiece to be processed.

[0057] The second moving portion 206 can be an electric cylinder, a pneumatic cylinder, or the like.

The four-axis mechanical arm has multiple degrees of freedom, can clamp the key 300 in different positions, and place it to the transfer mechanism 103. The four-axis mechanical arm has a gripper. The gripper is used to clamp the key 300. In addition, the four-axis mechanical arm also has a vision module. The vision module is used to determine whether the key 300 is successfully clamped by the gripper.

[0081] The transfer mechanism 103 is used to position the key 300 according to a set angle, so that the assembly mechanism 104 takes the key 300 and assembles it to the electronic module 302. The positioning mechanism 200 of the embodiment of the present application is located in the transfer mechanism 103. The positioning mechanism 200 can realize accurate positioning of the key 300 before assembly, so that the assembly mechanism 104 takes the key 300 in a suitable manner.

[0082] The assembly mechanism 104 is used to take the key 300 from the transfer mechanism 103 and assemble it to the electronic module 302. It should be noted that the structure of the key 300 is complex. The key 300 usually includes a connecting piece and two protruding parts, which are arranged along the length direction of the connecting piece and located on the same side of the connecting piece. When the transfer mechanism 102 clamps the key 300, the gripper is clamped at the part of the connecting piece between the two protruding parts. When the assembly mechanism 104 assembles the key 300, the assembly mechanism 104 takes the key 300 from the side of the connecting piece away from the two protruding parts, so that in the assembly station, the two protruding parts are inserted into the set position of the electronic module 302.

[0083] The electronic module 302 is placed into the magazine 105. The magazine 105 containing the electronic module 302 is transported from the starting position to the assembly station through the main flow line 107. In the assembly station, the electronic module 302 is transferred to the assembly mechanism 104, and then the assembly mechanism 104 assembles the key 300 to the electronic module 302. The assembled electronic module 302 is transferred to the next station. The empty magazine 105 is transferred to the return flow line 108 and transported to the starting position through the return flow line 108.

[0084] The key assembly device can realize automatic assembly of the key 300, has the characteristics of high assembly efficiency and high assembly precision.

[0085] In a specific embodiment of the present application, the assembly mechanism 104 includes a suction nozzle 1041, which is used to adsorb the key 300 positioned in the positioning groove 2012 and assemble it to the electronic module 302.

[0086] As Figure 6 , Figure 7As shown, the overall shape of the suction nozzle 1041 is cylindrical. An installation hole 1044 is arranged on the upper end surface of the suction nozzle 1041. The installation hole 1044 is used to install the moving shaft of the assembling mechanism 104. The moving shaft drives the suction nozzle 1041 to move. The lower end of the suction nozzle 1041 is provided with a suction hole 1043. The suction hole 1043 is used to suck air to adsorb the key 300 onto the suction nozzle 1041.

[0087] The assembling mechanism 104 takes the suction mode to take the key 300 from the transfer mechanism 103. For example, after the moving mechanism adheres the key 300 to the side wall and / or the positioning baffle of the positioning groove 2012, the suction nozzle 1041 of the assembling mechanism 104 sucks the key 300 from the side of the connecting piece away from the protruding part and transfers the key 300 to the assembling station. Then, the key 300 is assembled onto the electronic module 302. The suction mode of the suction nozzle 1041 can avoid the interference of the clamping jaw clamping mode to the side of the protruding part of the key 300, and improve the assembly efficiency and assembly precision of the key 300.

[0088] In one specific embodiment of the present application, the suction nozzle 1041 is provided with a groove 1042 for accommodating the key 300, and the bottom of the groove 1042 is provided with a suction port.

[0089] As shown in Figure 6 , Figure 7 The side of the suction nozzle 1041 is provided with a groove 1042. The shape of the groove 1042 matches the shape of the connecting piece. When sucking the key 300, the side of the connecting piece away from the protruding part is embedded in the groove 1042, and the two protruding parts are away from the suction nozzle 1041. The bottom of the groove 1042 is provided with a suction port. The arrangement of the groove 1042 makes the positioning of the key 300 on the suction nozzle 1041 more accurate. Optionally, the suction port is strip-shaped. The cross-sectional shape of the suction port matches the shape of the connecting piece, so that the suction force of the suction nozzle 1041 on the connecting piece is greater, and the suction of the key 300 is more firm.

[0090] Of course, the shape and size of the groove 1042 and the suction hole 1043 are not limited here, and those skilled in the art can set them according to actual needs.

[0091] The above embodiments mainly describe the differences between the various embodiments. The different optimization features between the various embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. Considering the brevity of the writing, it will not be repeated here.
