[0047] As shown in Figures 1 to 7 The present embodiment provides an earphone shell positioning tool, which comprises a support frame 100, a first movable positioning assembly 200 and a second movable positioning assembly 300. The support frame 100 has a mounting channel 110, and a part of the side wall of the mounting channel 110 forms a first fixed positioning part 111. The first movable positioning assembly 200 comprises a first movable positioning piece 210 movably arranged on the support frame 100 along a first direction, and the first movable positioning piece 210 has a first movable positioning part 211. The first movable positioning part 211 and the first fixed positioning part 111 cooperate to clamp a head part 1100 of an earphone shell 1000. The second movable positioning assembly 300 comprises a second movable positioning piece 310 and a connecting piece 320. The connecting piece 320 is arranged on the support frame 100 and extends along a second direction. The second movable positioning piece 310 is connected with the connecting piece 320, and the second movable positioning piece 310 can move between a closed position, an open position, a transfer position and an avoiding position. When the second movable positioning piece 310 is located at the closed position, a second movable positioning part on the second movable positioning piece 310 clamps a tail part 1200 of the earphone shell 1000 with a second fixed positioning part 120 on the bottom of the support frame 100. The open position is above the closed position, and the second movable positioning piece 310 rotates around the axis of the connecting piece 320 between the transfer position and the open position. The avoiding position is above the transfer position.

[0048] The first direction is the front-back direction, and the second direction is the up-down direction.

[0049] The head 1100 and the tail 1200 of the earphone shell 1000 are fixed by the first movable positioning assembly 200 and the second movable positioning assembly 300, so that the front surface, the back surface and the end of the tail 1200 of the earphone shell 1000 can be assembled, the number of tooling is reduced, the cost is reduced, the tooling replacement frequency is reduced, the assembly efficiency is improved, and the risk of scratching the appearance of the earphone shell 1000 is reduced. The second movable positioning member 310 is switched between the four positions, can complete the positioning of the earphone shell 1000, and can also avoid interference in the fixing process of the earphone shell 1000, thereby improving the assembly efficiency and the convenience of assembly.

[0050] The connecting member 320 is in the form of a rod, is arranged in the sliding channel 130 of the support frame 100 in the second direction, and can rotate relative to the support frame 100 around the axis of the sliding channel 130. The second movable positioning member 310 is connected with the connecting member 320, and the connecting member 320 can move between the raised position and the lowered position to drive the second movable positioning member 310 to move between the closed position and the open position, or to move between the transfer position and the avoiding position. In the embodiment, the cross section of the connecting member 320 is circular, and the cross section profile of the sliding channel 130 is also circular. The connecting member 320 moves in the sliding channel 130, can realize relative rotation of the connecting member 320 and the support frame 100 around the second direction, and can also realize relative movement of the two in the second direction, and the structure is simple and the relative movement is stable. In other embodiments, the connecting member 320 can be arranged in the sliding channel 130 in the second direction, and the second movable positioning member 310 is rotationally connected with the connecting member 320.

[0051] The second movable positioning assembly 300 includes an elastic member 330, which applies an elastic force to the connecting member 320 to make the connecting member 320 have a movement tendency to move to the raised position. The elastic member 330 is arranged to make the connecting member 320 automatically remain in the raised position when not subjected to external force, that is, to make the second movable positioning member 310 remain in the closed position or the avoiding position.

[0052] Regarding the structure of the elastic member 330, in some embodiments, the second movable positioning assembly 300 further comprises a blocking member 340, the sliding channel 130 comprises an upper channel and a lower channel connected in communication, the diameter of the upper channel is larger than that of the lower channel, the blocking member 340 is arranged in the upper channel, the connecting member 320 is arranged in the lower channel and the upper channel, the part of the connecting member 320 located in the upper channel is fixedly connected with the blocking member 340, the elastic member 330 is a spring, the spring is sleeved on the connecting member 320, and one end of the spring abuts against the support frame 100 and the other end abuts against the blocking member 340. Wherein, the lower end of the spring abuts against the step surface between the upper channel and the lower channel. When the connecting member 320 is located in the upper position, the blocking member 340 is located in the upper channel, so that the spring is always located in the upper channel and is protected by the support frame 100, thereby avoiding impurities from falling into the gap of the spring and ensuring that the elastic force is not affected.

[0053] Specifically, the second movable positioning assembly 300 further comprises a connecting screw 350, the blocking member 340 is a cylindrical structure, and in the direction close to the second movable positioning member 310, the inside of the blocking member 340 is sequentially connected with a first channel 341, a second channel 342, a third channel 343 and a fourth channel 344, wherein the diameter of the first channel 341 is larger than that of the second channel 342, the diameter of the third channel 343 is larger than that of the second channel 342 and smaller than that of the fourth channel 344, the diameter of the connecting member 320 is smaller than that of the third channel 343 and larger than that of the second channel 342, the diameter of the nut of the connecting screw 350 is smaller than that of the first channel 341 and larger than that of the second channel 342, the connecting member 320 is located in the third channel 343 and abuts against the step surface between the second channel 342 and the third channel 343, the connecting screw 350 is arranged in the first channel 341 and the second channel 342 and is screwed in the connecting screw hole of the connecting member 320. One end of the elastic member 330 is located in the fourth channel 344 and abuts against the step surface between the fourth channel 344 and the third channel 343.

[0054] The connecting member 320 is located in the third channel 343, which helps to improve the installation precision and efficiency. The nut of the connecting screw 350 is located in the first channel 341, avoiding exposure and improving the convenience of operation. When in use, the blocking member 340 is pressed downward to drive the connecting member 320 to move downward and drive the second movable positioning member 310 to move synchronously.

[0055] Regarding the connection between the second movable positioning member 310 and the connecting member 320, in some embodiments, the connecting member 320 is provided with a first locking hole 323, one end of the second movable positioning member 310 is provided with a mounting hole 315 and a second locking hole 316 connected to the mounting hole 315, the connecting member 320 is arranged in the mounting hole 315, and a locking member is arranged in the first locking hole 323 and the second locking hole 316. The connecting member 320 is in a cylindrical structure, which is convenient for processing and reduces the cost. The locking member helps to prevent relative rotation between the second movable positioning member 310 and the connecting member 320. Further, the connecting member 320 includes a connecting body 321 and a connecting limiting portion 322 arranged at one end of the connecting body 321, and the diameter of the mounting hole 315 is smaller than the diameter of the connecting limiting portion 322 and larger than the diameter of the connecting body 321, so that when the connecting member 320 rises, the connecting limiting portion 322 pushes the second movable positioning member 310, avoiding the stress on the locking member, and improving the durability of the locking member.

[0056] When the second movable positioning member 310 is in the closed position or the avoiding position, the elastic member 330 applies an elastic force to the blocking member 340, driving the connecting member 320 to move upward, so that the connecting limiting portion 322 drives the second movable positioning member 310 upward to keep it in the closed position or the avoiding position.

[0057] Further, the second movable positioning assembly 300 further includes a damping member arranged between the second movable positioning member 310 and the support frame 100. When the second movable positioning member 310 is in the avoiding position, the damping member is clamped to improve the friction between the two, further ensuring the reliability of the second movable positioning member 310 remaining in the avoiding position, avoiding the second movable positioning member 310 from moving during the process of installing the earphone shell 1000 to the earphone shell positioning tool. In this embodiment, the damping member is a rubber ring, which is sleeved on the connecting member 320. When the second movable positioning member 310 is in the closed position, the damping member is clamped between the second movable positioning member 310 and the support frame 100, thereby ensuring the stability of the second movable positioning member 310 in the closed position.

[0058] In other embodiments, the side of the second movable positioning member 310 facing the support frame 100 is provided with a plug-in protrusion, and the support frame 100 is provided with two plug-in grooves. When the second movable positioning member 310 is in the closed position, the plug-in protrusion on the second movable positioning member 310 is inserted into one of the plug-in grooves, and when the second movable positioning member 310 is in the avoiding position, the plug-in protrusion on the second movable positioning member 310 is inserted into the other plug-in groove.

[0059] The second movable positioning member 310 has a positioning groove 313 formed on the second movable positioning member 310, the positioning groove 313 extends along the first direction and penetrates the second movable positioning member 310, and forms a positioning channel with the second fixed positioning member 120 to accommodate and position the tail 1200 of the earphone shell 1000. The tail 1200 is long strip-shaped, and the tail 1200 is located in the positioning channel and is combined with the positioning of the first movable positioning member 210 to realize the all-around fixation of the earphone shell 1000. In the second direction, the length of the tail 1200 is greater than the length of the positioning channel, so that the end of the tail 1200 away from the head 1100 is exposed, facilitating assembly with other components.

[0060] The second movable positioning member 310 includes a positioning body 311 and a positioning end 312, the positioning end 312 is inserted into a positioning slot of the positioning body 311 and is fixed by a pin, and the positioning groove 313 is arranged on the positioning end 312. When the earphone model is changed, the positioning end 312 can be replaced, thereby reducing the cost. Further, the positioning groove 313 is a V-shaped groove, so that the same positioning end 312 can adapt to more models of earphones.

[0061] To ensure the positioning reliability of the second movable positioning member 310, in some embodiments, the other end of the second movable positioning member 310 has a clamping groove 314, and two connecting members 320 are arranged along a third direction and are located on both sides of the positioning channel, the two connecting members 320 can move between a raised position and a lowered position, the second movable positioning member 310 is connected to one of the connecting members 320 through a mounting hole 315 and is detachably connected to the other connecting member 320 through the clamping groove 314. The third direction is the left-right direction. The other connecting member 320 can also apply an upward force to the second movable positioning member 310, so that the second movable positioning member 310 is uniformly stressed, and the tail 1200 of the earphone shell 1000 is more stably crimped. Among them, the second movable positioning assembly 300 includes two elastic members 330, two blocking members 340 and two connecting screws 350, each elastic member 330, connecting member 320, blocking member 340 and connecting screw 350 form a telescopic group, and the two telescopic groups have the same structure and connection mode, which will not be described in detail here.

[0062] In some embodiments, the line between the first movable positioning member 210 and the first fixed positioning member 111 extends along a fourth direction and is arranged at an acute angle with the first direction, and the included angle is α. The size of the first movable positioning member 210 in the first direction is smaller, which helps to reduce the size of the earphone shell positioning tool in the first direction. The side of the first movable positioning assembly 200 close to the end of the mounting channel 110 has an arc surface to form the first movable positioning member 211. Among them, the arc surface and the contour of the earphone shell 1000 are adapted to increase the contact area and avoid stress concentration.

[0063] To improve the assembly efficiency, the support frame 100 has two mounting channels 110 corresponding to two earphone housings 1000 respectively; the first movable positioning member 210 has two first movable positioning portions 211 corresponding to two first fixed positioning portions 111 in the two mounting channels 110 respectively to clamp the two earphone housings 1000 respectively. Wherein, along the third direction, the two first movable positioning portions 211 are located between the two earphone housings 1000. The position arrangement of the two first movable positioning portions 211 can avoid the position of the assembly of the earphone housings 1000 and other components, and in the third direction, it is helpful to reduce the size of the first movable positioning member 210.

[0064] The first movable positioning member 210 is slidingly arranged in the support frame 100 and has a separation position away from the first fixed positioning portion 111 and a clamping position close to the first fixed positioning portion 111, and the first movable positioning assembly 200 includes a magnetic member 220 which can apply a magnetic force to the first movable positioning member 210 in the clamping position to keep the first movable positioning member 210 in the clamping position. Specifically, in the first embodiment of the present embodiment, the magnetic member 220 is arranged on the first movable positioning member 210, and the support frame 100 is made of stainless steel or other materials that can be attracted by magnetic force. In the second embodiment of the present embodiment, the magnetic member 220 is arranged on the support frame 100, and the first movable positioning member 210 is made of stainless steel or other materials that can be attracted by magnetic force. In the third embodiment of the present embodiment, the magnetic member 220 has two, one of which is arranged on the first movable positioning member 210, and the other is arranged on the support frame 100. In the third embodiment of the present embodiment, the magnetic member 220 has a columnar structure and extends along the second direction, and the opposite ends of the two magnetic members 220 have opposite magnetic poles. In other words, when the first movable positioning member 210 is in the clamping position, the axes of the two magnetic members 220 coincide. In some embodiments, when the first movable positioning member 210 is in the clamping position, the two magnetic members 220 partially coincide, and the axes of the two magnetic members 220 do not coincide, and the axis of the magnetic member 220 on the support frame 100 is located between the axis of the magnetic member 220 on the first movable positioning member 210 and the first fixed positioning portion 111, so that the first movable positioning member 210 has a movement trend close to the first fixed positioning portion 111 to clamp the earphone housing 1000.
