Description

Technical Field

[0001] The present invention relates to the field of electronic product assembly, and particularly to a Bluetooth headset automatic assembly machine for assembling ear machine components into a headset body. Background Art

[0002] With the rapid development of science and technology, people's requirements for the quality of electronic products such as mobile phones, tablet computers, and headsets are getting higher and higher. While demanding high quality, they also pursue a stylish appearance. Therefore, more and more electronic products are designed to be smaller, thinner, and lighter, and have a certain curvature. As a result, electronic products are developing towards high-density integration and ultra-fine precision. Correspondingly, the requirements for electronic product assembly equipment are also getting higher and higher.

[0003] Especially for Bluetooth headsets, the Bluetooth headsets on the market generally adopt an integrated structure. Ear machine components such as PCB boards, batteries, charging modules, and antenna modules are all encapsulated in the headset body. The ear machine components of Bluetooth headsets are generally assembled by first aligning and connecting them and then bonding them with glue. Glue application and assembly are both difficult. And because Bluetooth headsets are very delicate in themselves, when their bodies have a certain curvature, it makes the assembly of more delicate ear machine components in the body even more difficult. General assembly equipment is difficult to achieve precise and efficient bonding. Therefore, the assembly of components of a Bluetooth headset with a curvature on the body generally still adopts a manual operation method, and manual operation has low efficiency and cannot effectively guarantee the precision of glue application and the firmness of assembly.

[0004] Therefore, there is an urgent need for a Bluetooth headset automatic assembly machine that can achieve automatic operation, has a simple structure, high efficiency, high assembly precision, and good effect to overcome the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a Bluetooth headset automatic assembly machine with a simple structure, high automation degree, high efficiency, high assembly precision, and good effect.

[0006] To achieve the above object, the present invention discloses a Bluetooth headset automatic assembly machine for assembling earphone components into an earphone body. A fitting area is provided at the arc-shaped inner wall of the earphone body. The Bluetooth headset automatic assembly machine includes a first carrier, a second carrier, a pushing device, and a pressing device. The first carrier is used to fix the earphone body, and the second carrier is used to fix the earphone components. With the cooperation of the second carrier, the pushing device pushes the earphone components into the earphone body, so that the relative front end of the earphone components abuts against the fitting area. The first pressing head of the pressing device can extend into the earphone body and press the earphone components located in the fitting area in a direction perpendicular to the pressed surface of the earphone components, so that the pressure-sensitive adhesive provided between the earphone body and the earphone components is activated, thereby realizing the adhesion between the two.

[0007] Preferably, the Bluetooth headset automatic assembly machine further includes a working platform. The first carrier, the second carrier, and the pushing device are arranged on the working platform and are linearly arranged on the working platform. The pressing device is erected on the working platform and is located above the first carrier.

[0008] Preferably, the first carrier includes a profiling groove, a first positioning member, a second positioning member, and a third positioning member. The earphone body is placed horizontally in the profiling groove. The first positioning member and the second positioning member are respectively arranged on the front side and the rear side of the profiling groove to fix the earphone body from both ends. The third positioning member is arranged on the left side or the right side of the profiling groove to fix the wiring harness in the earphone body.

[0009] Preferably, the first positioning member can move linearly up and down relative to the profiling groove and can be locked at a position where it abuts against the front end of the earphone body. The second positioning member can rotate relative to the profiling groove and can be buckled with the rear end of the earphone body. The third positioning member can rotate relative to the profiling groove and can dial the wiring harness in the earphone body to the edge of the earphone body.

[0010] Preferably, the second carrier includes a card slot and two clamping members symmetrically arranged with the card slot as the center. The earphone components can be slidably inserted into the card slot. The two clamping members can move towards each other or away from each other to clamp or loosen the earphone components located in the card slot.

[0011] Preferably, the second carrier further includes an operating member and a first driving member. The operating member and the first driving member are slidably or rotatably connected. The first driving member is arranged in a linked manner with the two clamping members. The relative rotation or sliding between the operating member and the first driving member can drive the two clamping members to move towards each other or away from each other.

[0012] Preferably, the pushing device includes a pushing member, a second driving member, a limiting member, and a locking member. The second driving member is connected to the pushing member to drive the pushing member to linearly move in the direction of the first carrier, so that the pushing member pushes the earphone component to the position of the fitting area in the earphone body. The limiting member is arranged along the moving direction of the pushing member and is used for limiting the pushing member to move in place. The locking member is arranged beside the pushing member and is used for locking the pushing member at the position where the earphone component is pushed in place.

[0013] Preferably, the second driving member is slidably arranged on the rear side of the second carrier through a linear guide rail. The rear end of the pushing member is connected to the driving member, and the front end of the pushing member is movably inserted into the second carrier. One limiting member is arranged on each of the front and rear sides of the second driving member. When the second driving member abuts against the front limiting member, the side end of the second driving member is simultaneously clamped with the locking member.

[0014] Preferably, the pressing device further includes a pressing driving mechanism connected to the first pressing head. The pressing driving mechanism is arranged obliquely relative to the first carrier, so that the pressing surface of the first pressing head is parallel to the pressed surface of the earphone component. The pressing driving mechanism can drive the first pressing head to move in a direction perpendicular to the pressed surface, and the pressing driving mechanism can also drive the first pressing head to move in a direction parallel to the pressed surface within the earphone body.

[0015] Preferably, the pressing device further includes a second pressing head. The second pressing head is L-shaped, and the height of the pressing end of the second pressing head is less than the distance between the microphone on the earphone component and the inner wall of the earphone body. The second pressing head can vertically extend into the earphone body relatively, so that the pressing end presses on the microphone to perform secondary pressure maintaining on the earphone component that has been pressure maintained once by the first pressing head.

[0016] Compared with the prior art, the automatic assembly machine for Bluetooth earphones of the present invention is used to assemble earphone components into an earphone body with a certain curvature. It includes a first carrier, a second carrier, a pushing device and a pressing device. The earphone body and the earphone components are respectively fixed by the first carrier and the second carrier. With the cooperation of the second carrier, the pushing device pushes the earphone components in the second carrier towards the direction of inserting into the earphone body, so that the earphone components are pushed to the fitting area inserted into the earphone body. Since this fitting area is located at the arc-shaped inner wall of the earphone body, the first pressing head of the pressing device can extend into the earphone body and press the earphone components located in the fitting area along the direction perpendicular to the pressed surface of the earphone components, so that the pressure-sensitive adhesive preset between the earphone body and the earphone components is activated, thereby realizing the adhesion between the two. The structure of this machine is simple. By using the method of activating the preset pressure-sensitive adhesive through pressure, the adhesion between components in a limited and irregular-shaped space is realized, improving the prior art assembly method of first aligning and then dispensing glue. The assembly is easier and the processing accuracy is higher. It can also effectively reduce the problem of contaminating electronic components due to dispensing glue after alignment assembly.

[0032] To describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with the implementation manners and with reference to the drawings.

[0033] Please refer to Figure 1 and Figure 2 , the present invention relates to the assembly of a Bluetooth headset 200, and the Bluetooth headset 200 includes a headset body 201 and ear machine components 202 assembled in the headset body 201. In this application, the ear machine components 202 include but are not limited to a headset antenna, and a microphone 203 can be connected to the relative front end of the headset antenna. The headset body 201 has a certain curvature as a whole, and specifically includes an earplug part 2011 and a handle part 2012. Among them, the earplug part 2011 is large at the top and small at the bottom in a horn shape, the handle part 2012 is in a straight tube shape, and the connection part 2013 between the earplug part 2011 and the handle part 2012 has a certain curvature, so that the connection part 2013 of the headset body 201 forms an arc-shaped inner wall. When the ear machine components 202 are assembled in the headset body 201, the relative front end of the ear machine components 202 abuts against this arc-shaped inner wall. In order to achieve a firm connection between the ear machine components 202 and the headset body 201, they are fixed with glue, so a fitting area is provided at the arc-shaped inner wall of the headset body 201. The present invention provides an automatic assembly machine for a Bluetooth headset, which is used to push the ear machine components 202 in place until the front end of the ear machine components 202 is located in the fitting area of the headset body 201, and then by pressing the ear machine components 202, the pressure-sensitive adhesive 300 preset at the fitting area of the headset body 201 or the bottom surface of the relative front end of the ear machine components 202 is activated, so as to achieve a firm bond between the headset body 201 and the ear machine components 202. Preferably, the pressure-sensitive adhesive 300 is provided at the fitting area of the headset body 201, which is convenient for assembly.

[0034] Please refer to Figures 1 to 15, the automatic Bluetooth headset assembly machine 100 disclosed in the preferred embodiment of the present invention includes a first carrier 10, a second carrier 20, a pushing device 30 and a pressing device 40. The first carrier 10 is used to fix the headset body 201, and the second carrier 20 is used to fix the headset components 202. With the cooperation of the second carrier 20, the pushing device 30 pushes the headset components 202 into the headset body 201, so that the relative front end of the headset components 202 abuts against the bonding area, that is, the bottom surface of the relative front end of the headset components 202 abuts against the pressure-sensitive adhesive 300 in the bonding area. The first pressing head 41 of the pressing device 40 can extend into the headset body 201 and press the headset components 202 located in the bonding area in a direction perpendicular to the pressed surface of the headset components 202, so that the pressure-sensitive adhesive 300 provided between the headset body 201 and the headset components 202 is activated, thereby realizing the bonding of the two. The automatic Bluetooth headset assembly machine 100 disclosed in the present invention further includes a control system electrically connected to the first carrier 10, the second carrier 20, the pushing device 30 and the pressing device 40, and the control system controls the coordinated actions between the devices. It should be noted that the control system is an existing control system, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0035] Please refer to Figure 3 and Figure 4 , the automatic Bluetooth headset assembly machine 100 of the present invention further includes a lower chassis 50 and an upper chassis 60 arranged vertically. The upper chassis 60 is provided with a touch screen 61 for operation and a buzzer 62 for alarm. The electrical control components of the control system are respectively arranged in the lower chassis 50 and the upper chassis 60. The lower chassis 50 has a working platform 51, and the lower chassis 50 is also provided with control buttons 52 for operation. The first carrier 10, the second carrier 20 and the pushing device 30 are arranged on the working platform 51, and the three are arranged in a straight line on the working platform 51, so as to effectively shorten the movement stroke of the pushing device 30 and accurately and effectively push the headset components 202 into the headset body 201. The pressing device 40 is fixed in the upper chassis 60 and is erected on the working platform 51, and the pressing device 40 is located above the first carrier 10, so as to facilitate the up and down movement of the pressing device 40 to press the headset components 202.

[0036] For the convenience of loading and unloading materials, a carrier plate 53 is provided on the working platform 51. The first carrier 10, the second carrier 20 and the pushing device 30 are installed on the carrier plate 53, and the three are arranged in a straight line along the transverse width direction of the working platform 51 on the carrier plate 53. Either the carrier plate 53 or the pressing device 40 can move linearly relative to the other along the longitudinal length direction of the working platform 51, so that the first carrier 10 is positioned directly below the pressing device 40 or away from the pressing device 40. Thus, through the design of making way, it is convenient for loading and unloading materials and effectively reduces the floor space of the whole machine. More specifically, in this embodiment, the carrier plate 53 is slidably arranged on the linear guide 54 of the working platform 51, so that it can move linearly back and forth relative to the pressing device 40. Preferably, a bellows guide shield 55 is also provided on the linear guide 54.

[0037] Continue to refer to Figure 3 and Figure 4 , the automatic assembly machine 100 of the Bluetooth headset of the present invention further includes a vision detection device 70. The vision detection device 70 is installed on the side wall of the upper chassis 60 and is located above the first carrier 10, and is used for visual detection of whether the headset components 202 are pushed in place, and feeds back the detection result to the control system. Specifically, the vision detection device 70 includes a CCD camera 71 and a rotating assembly 72 for driving the CCD camera 71 to rotate. One end of the rotating assembly 72 is connected to the upper chassis 60, and the other end thereof is connected to the CCD camera 71. When detection is required, the rotating assembly 72 can drive the CCD camera 71 to rotate above the first carrier 10 for visual recognition, thereby improving the assembly accuracy.

[0038] Please refer to Figures 5 to 7 , since the earphone body 201 has a certain curvature and there is a certain height difference between its earplug part 2011 and the handle part 2012, in order to better fix the earphone body 201, the first carrier 10 includes a profiling groove 10a, a first positioning member 11, a second positioning member 12 and a third positioning member 13. The profiling groove 10a corresponds to the shape of the outer contour of the earphone body 201. The earphone body 201 is placed horizontally in the profiling groove 10a. The first positioning member 11 and the second positioning member 12 are respectively arranged on the front side and the rear side of the profiling groove 10a to fix the earphone body 201 from both ends. The third positioning member 13 is arranged on the left side or the right side of the profiling groove 10a to fix the wiring 400 in the earphone body 201.

[0039] Among them, the first positioning member 11 can move linearly up and down relative to the profiling groove 10a and can be self-locked at a position where it abuts against the front end of the earphone body 201, so as to fix the earplug part 2011. The first positioning member 11 is specifically a push-type lock. The second positioning member 12 can rotate relative to the profiling groove 10a and can be buckled with the rear end of the earphone body 201, so as to fix the handle part 2012. The second positioning member 12 is specifically strip-shaped. One end of it is pivotally connected to the first carrier 10 to form a pivot end, and the other end is a free end. A card slot is provided on the free end. The free end can rotate around the pivot end, so that the card slot is engaged with the positioning post 14 on the first carrier 10, thereby locking the handle part 2012 between the profiling groove 10a and the second positioning member 12. The third positioning member 13 can also rotate relative to the profiling groove 10a and can send the wiring 400 in the earphone body 201 to the edge of the earphone body 201, so as to facilitate the pressing operation of the pressing device 40. Specifically, one end of the third positioning member 13 is pivotally connected to the first carrier 10, and the other end can rotate relative to the profiling groove 10a, so as to send the wiring 400 in the earphone body 201 to the edge of the earphone body 201 and can be locked at this position through the locking nut 131 to maintain the fixation of the wiring 400.

[0040] Specifically, in order to ensure the fixation of the first carrier 10 on the carrier plate 53, positioning pins 531 and limiting blocks 532 are provided on the carrier plate 53. The limiting blocks 532 are L-shaped. Two limiting blocks 532 are symmetrically arranged on the left and right sides of the carrier plate 53, and a limiting space is defined between the two limiting blocks 532. A positioning pin 531 is provided beside each limiting block 532 within the limiting space. The first carrier 10 is provided with positioning holes 10b corresponding to the positioning pins 531, and the first carrier 10 is fixed in the limiting space through the alignment of the positioning pins 531 and the positioning holes 10b. Further, in order to prevent the first carrier 10 from moving back and forth during the pushing and pressing processes, a clamping cylinder 533 and a clamping block 534 connected to the output end of the clamping cylinder 533 are also provided on the carrier plate 53. To optimize the structure, the clamping cylinder 533 is provided at the bottom end of the carrier plate 53, and the clamping block 534 is provided at the front end of the carrier plate 53. The clamping block 534 can perform a linear motion of approaching or departing from the front side wall of the first carrier 10 under the drive of the clamping cylinder 533, so as to clamp the first carrier 10 between the clamping block 534 and the limiting block 532 or release the first carrier 10, thereby effectively improving the assembly accuracy.

[0041] Please refer to Figure 5 、 Figures 8 to 11The second carrier 20 includes a slot 20a and two clamping members 21 symmetrically arranged with the slot 20a as the center. The slot 20a corresponds to the shape of the outer contour of the earphone device 202. The earphone device 202 can be slidably inserted into the slot 20a. The two clamping members 21 can move toward or away from each other to clamp or release the earphone device 202 in the slot 20a. The second carrier 20 also includes an operating member 22 and a first driving member 23. The operating member 22 is slidably connected to the first driving member 23 or rotatably connected. The first driving member 23 and the two clamping members 21 are arranged in a linked manner. The relative rotation or sliding between the operating member 22 and the first driving member 23 can drive the two clamping members 21 to move toward or away from each other, thereby clamping or releasing the earphone device 202.

[0042] Specifically, in this embodiment, the operating member 22 is block-shaped or rod-shaped. The first driving member 23 includes a connecting portion 231 and a plug-in portion 232 with a certain taper. The connecting portion 231 and the operating member 22 are rotatably or slidably connected, and the plug-in portion 232 is embedded in the two clamping members 21 in a linearly movable manner. The operating member 22 can move or rotate to drive the first driving member 23 to perform linear reciprocating motion, so that the plug-in portion 232 embedded in the two clamping members 21 loosens or spreads the two clamping members 21 due to the certain taper, thereby driving the two clamping members 21 to move toward or away from each other, thereby clamping or loosening the earphone device 202 in the slot 20a. In addition, during the process of the two clamping members 21 moving toward each other, the earphone device 202 in the slot 20a can also be adjusted in position. Preferably, the second carrier 20 also includes a first elastic member 24 and a second elastic member 25. The first elastic member 24 is disposed between the two clamping members 21 to constantly drive the two clamping members 21 to move toward each other. The second elastic member 25 is disposed between the operating member 22 and the second carrier 20 or between the first driving member 23 and the second carrier 20 to constantly drive the operating member 22 or the first driving member 23 to move toward returning to the original position.

[0043] More specifically, the second vehicle 20 is installed on the carrier plate 53 through a bottom plate 56. The second vehicle 20 further includes a mounting seat 26 fixed to the relative front end of the bottom plate 56. The two clamping members 21, the operating member 22, the driving member 23, the first elastic member 24 and the second elastic member 25 are all installed on the mounting seat 26. The card slot 20a is arranged at the top side end of the mounting seat 26 and along the transverse width direction of the mounting seat 26, and has a connected clamping section 20b and a guiding section 20c. The ear machine component 202 is placed in the clamping section 20b, and the pushing device 30 accurately pushes against the ear machine component 202 in the clamping section 20b through the guidance of the guiding section 20c. The two clamping members 21 are symmetrically arranged at the relative front ends of the mounting seat 26 and are located on the left and right sides of the card slot 20a. The clamping member 21 is in a C shape. The distance between the upper end portions of the two clamping members 21 corresponds to the slot width of the card slot 20a and is relatively wider, so as to clamp the ear machine component 202 in the card slot 20a from both sides; while the distance between the lower end portions of the two clamping members 21 is relatively narrower, and even in a butt-jointed setting, so as to facilitate the insertion portion 232 to be embedded between the two. The operating member 22, the first driving member 23 and the second elastic member 25 are all arranged at the relative rear end of the mounting seat 26 and are partially or entirely received in the accommodating cavity of the mounting seat 26.

[0044] Among them, the operating member 22 is an L-shaped pushing block. Its short side is located outside the mounting seat 26 for easy pushing and pulling operation. Its long side slides in the accommodating cavity of the mounting seat 26, and a second elastic member 25 is connected between the long side of the operating member 22 and the mounting seat 26; the first driving member 23 is generally cylindrical. Its insertion portion 232 is smaller at the front and larger at the rear and is in a frustum shape. Its connecting portion 231 is in a rod shape and has a connecting end extending along the radial direction of the first driving member 23. An inclined slot 22a is provided on the long side of the operating member 22. The connecting portion 231 slides in the inclined slot 22a through the connecting end; then push and pull the operating member 22, so that the operating member 22 makes a linear motion close to or away from the mounting seat 26, thereby driving the first driving member 23 to make a linear motion close to or away from the two clamping members 21, so that the two clamping members 21 move away from each other or move towards each other to loosen or clamp the ear machine component 202. Preferably, a third elastic member 27 (see Figure 11 ) can be additionally provided between the mounting seat 26 and the clamping member 21, so that the movement of the two clamping members 21 is smoother and faster. The first elastic member 24, the second elastic member 25 and the third elastic member 27 are all springs. It should be noted that the operating member 22 can be manually operated with a simple structure, or can be connected to a driver to realize automatic operation.

[0045] Please refer to Figure 5 、 Figure 10 and Figure 11The pushing device 30 is arranged at the relatively rear end of the bottom plate 56. The pushing device 30 includes a pushing member 31, a second driving member 32, a limiting member 33 and a locking member 34. The second driving member 32 is connected to the pushing member 31 to drive the pushing member 31 to move linearly, so that the pushing member 31 pushes the earphone component 202 to the position of the fitting area of ​​the earphone body 201. The limiting member 33 is arranged along the moving direction of the pushing member 31, and is used to limit the movement of the pushing member 31 into position. The locking member 34 is arranged on the side of the pushing member 31, and is used to lock the pushing member 31 at the position where the earphone component 202 is pushed into position.

[0046] Specifically, the second driving member 32 is slidably disposed on the rear side of the second carrier 20 through a linear guide rail 35, the rear end portion 311 of the pushing member 31 is connected to the second driving member 32, and the front end portion 312 of the pushing member 31 is movably inserted into the second carrier 20. More specifically, the pushing member 31 is generally shovel-shaped, the front end portion 312 is relatively narrow and the rear end portion 311 is relatively wide, and the front end portion 312 is relatively low and the rear end portion 311 is relatively high, the rear end portion 311 is slidably abutted against the top end surface of the mounting seat 26, and the front end portion 312 is inserted into the clamping section 20b from the guide section 20c of the clamping slot 20a, so as to achieve the abutment and pushing of the earphone device 202 in the clamping section 20b.

[0047] Specifically, a limiting member 33 is provided on each of the front and rear sides of the second driving member 32, and when the second driving member 32 abuts against the limiting member 33 on the front side, the side end 321 of the second driving member 32 is simultaneously engaged with the locking member 34. More specifically, the limiting member 33 is block-shaped, plate-shaped or column-shaped, and the locking member 34 is engaged with the side end 321 in a concave-convex matching manner.

[0048] Specifically, in this embodiment, in order to simplify the structure and facilitate manual operation, a handle 322 is provided on the second driving member 32, and the handle 322 is provided at a fixed side end of the second driving member 32. Preferably, the side end 321 of the second driving member 32 can be engaged with the locking member 34 to play a role in keeping the push in place, and when the second driving member 32 moves backward, it can also abut against the rear limiting member 33 to play a role in limiting.

[0049] See also Figures 12 to 15, the pressing device 40 further includes a pressing drive mechanism 42 connected to the first pressing head 41. The pressing drive mechanism 42 is inclined relative to the first carrier 10, such that the pressing surface of the first pressing head 41 is parallel to the pressed surface of the earpiece component 202. The pressing drive mechanism 42 can drive the first pressing head 41 to move obliquely downward in a direction perpendicular to the pressed surface, so that the first pressing head 41 can extend into the earphone body 201. The pressing drive mechanism 42 can also drive the first pressing head 41 to move obliquely backward in a direction parallel to the pressed surface within the earphone body 201, so that the first pressing head 41 moves above the earpiece component 202. Then the pressing drive mechanism 42 drives the first pressing head 41 to move obliquely downward in a direction perpendicular to the pressed surface to press against the earpiece component 202, thereby activating the pressure-sensitive adhesive 300 provided on the earphone body 201, and further realizing the adhesion between the earpiece component 202 and the earphone body 201.

[0050] Combined Figure 4 , Figure 12 and Figure 13 , the pressing drive mechanism 42 includes a first mounting plate 421 and a second mounting plate 422 arranged in parallel and spaced apart vertically, a motor 423 provided on the first mounting plate 421, a lead screw 424 connected to the output end of the motor 423, a cylinder 425 provided on the second mounting plate 422, and at least two guide rods 426 symmetrically connected between the first mounting plate 421 and the second mounting plate 422. The lead screw 424 also passes through the center of the second mounting plate 422 through a bearing. The first pressing head 41 is connected to the output end of the cylinder 425. The first mounting plate 421 is inclined and installed in the upper chassis 60, such that the entire pressing drive mechanism 42 is inclined relative to the first carrier 10, thereby ensuring that the pressing surface of the first pressing head 41 is parallel to the pressed surface of the earpiece component 202. The motor 423 first drives the first pressing head 41 to move obliquely downward in a direction perpendicular to the pressed surface, so that the first pressing head 41 extends into the earphone body 201. Then the cylinder 425 drives the first pressing head 41 to move obliquely backward in a direction parallel to the pressed surface within the earphone body 201, so that the first pressing head 41 moves above the earpiece component 202. Then the motor 423 drives the first pressing head 41 to move obliquely downward in a direction perpendicular to the pressed surface, thereby pressing vertically against the earpiece component 202. The moving direction of the first pressing head 41 is as shown by the F direction indicated by the arrow in Figure 4 as shown.

[0051] Specifically, in order to achieve the precise movement of the first indenter 41 and effectively protect the earphone components 202, the pressing drive mechanism 42 further includes a position sensor 427, a buffer module 428, and a pressure sensor 429. The position sensor 427 is disposed on the first mounting plate 421 or the second mounting plate 422 and is used to sense whether the guide rod 426 sleeved in the linear bearing moves into place. The buffer module 428 includes a connecting plate 4281 connected to the output shaft of the air cylinder 425, a linear slide rail 4282 disposed on the connecting plate 4281, an elastic member 4283, and a buffer 4284 disposed at the side end of the second mounting plate 422. The first indenter 41 slides on the linear slide rail 4282. The pressure sensor 429 is disposed between the connecting plate 4281 and the first indenter 41, and the pressure sensor 429 is connected to the first indenter 41 through a positioning column 4285. The elastic member 4283 is sleeved on the positioning column 4285, thereby effectively preventing the problem that the first indenter 41 moves too fast or applies too much pressure under the drive of the motor 423 and damages the earphone components 202. The buffer 4284 is used to prevent the problem that the first indenter 41 moves too fast under the drive of the air cylinder 425.

[0052] Please refer to Figure 1 , Figure 2 , Figure 14 and Figure 15 , since the pressure-sensitive adhesive 300 is disposed at the arc-shaped inner wall of the earphone body 201, and the first indenter 41 relatively presses against the front section 202a of the relatively front end of the earphone component 202, and the contact surface is relatively small. Therefore, in order to more effectively activate the pressure-sensitive adhesive 300 and thus improve the bonding firmness, the pressing device 40 of the present invention further includes a second indenter 43. The second indenter 43 is L-shaped, and the height of the pressing end 431 of the second indenter 43 is less than the distance between the microphone 203 on the earphone component 202 and the inner wall of the earphone body 201. The second indenter 43 can vertically extend into the earphone body 201 relatively, so that the pressing end 431 vertically presses against the microphone 203, and can press against the rear section of the relatively front end of the earphone component 202 at the microphone 203 to perform secondary pressing on the earphone component 202 that has been subjected to primary pressing by the first indenter 41, so that the pressure-sensitive adhesive 300 at the arc-shaped inner wall is fully activated, thereby effectively improving the adhesion between the earphone component 202 and the earphone body 201. It should be noted that in this embodiment, the second indenter 43 is manually operated to simplify the structure and reduce the cost. In other embodiments, the second indenter 43 can also be connected to a drive mechanism to improve the efficiency. In addition, both the first indenter 41 and the second indenter 43 are rubber-coated indenters, so that each component of the Bluetooth earphone 200 can be effectively protected during the pressing process.

[0053] The working principle of the Bluetooth earphone automatic assembly machine 100 of the present invention will be described below in conjunction with Figures 1 to 15 :

[0054] First, after starting the device, at the initial position, place the earphone body 201 and the earphone component 202 on the first carrier 10 and the second carrier 20 respectively. Then, manually operate the first positioning member 11, the second positioning member 12 and the third positioning member 13 to fix the earphone body 201. And the operating member 22 can be pushed and pulled to make the two clamping members 21 perform alignment adjustment on the earphone component 202. After that, push the operating member 22 to make the two clamping members 21 release the earphone component 202. Then, operate the handle 322 to drive the pushing member 31 to push the earphone component 202 in the second carrier 20 in the direction of inserting into the earphone body 201, so that the earphone component 202 is pushed to the fitting area where it is inserted into the earphone body 201. During this process, the visual detection device 70 detects whether the earphone component 202 is pushed in place and feeds the detection result back to the control system. After the detection is in place, under the instruction of the control system, the carrier plate 53 moves to the position below the first carrier 10 where the pressing device 40 is located. The pressing drive mechanism 42 drives the first pressing head 41 to extend into the earphone body 201 and press the earphone component 202 in the fitting area along the direction perpendicular to the pressed surface of the earphone component 202, so that the pressure-sensitive adhesive 300 preset between the earphone body 201 and the earphone component 202 is activated, thereby realizing the primary bonding of the two. After that, both the carrier plate 53 and the pressing device 40 are reset. Manually insert the second pressing head 43 into the earphone body 201 and press the earphone component 202 at the microphone 203, thereby realizing the secondary bonding of the earphone body 201 and the earphone component 202 that have been primarily bonded. Finally, the assembled Bluetooth earphone 200 is taken off, and a new earphone body 201 and earphone component 202 to be assembled are put in. By continuously repeating the above operations, the automatic operation of assembling the earphone component 202 into the earphone body 201 can be realized.

[0055] Compared with the prior art, the Bluetooth headset automatic assembly machine 100 of the present invention is used to assemble the earphone components 202 into the earphone body 201 with a certain curvature. It includes a first carrier 10, a second carrier 20, a pushing device 30 and a pressing device 40. The earphone body 201 and the earphone components 202 are respectively fixed by the first carrier 10 and the second carrier 20. With the cooperation of the second carrier 20, the pushing device 30 pushes the earphone components 202 in the second carrier 20 towards the direction of inserting into the earphone body 201, so that the earphone components 202 are pushed to the fitting area inserted into the earphone body 201. Since this fitting area is located at the arc-shaped inner wall of the earphone body 201, the first pressing head 41 of the pressing device 40 can extend into the earphone body 201 and press the earphone components 202 located in the fitting area along the direction perpendicular to the pressed surface of the earphone components 202, so that the pressure-sensitive adhesive 300 preset between the earphone body 201 and the earphone components 202 is activated, thereby realizing the adhesion of the two. The structure of this machine is simple. By applying the pressure-sensitive adhesive to at least one of the earphone body 201 and the earphone components 202 before assembly and then activating the pressure-sensitive adhesive 300 through pressure to realize the adhesion of the two, it improves the prior art assembly method of first aligning and then dispensing glue in a limited space. The assembly is easier and the processing accuracy is higher. It can also effectively reduce the problem of contaminating electronic components due to dispensing glue after alignment and assembly.

[0056] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
