Description

Technical Field

[0001] The present invention belongs to the technical field of welding processing, and particularly relates to a welding device for assembling a communication earphone diaphragm. Background Art

[0002] The sound of an earphone is generated by a diaphragm sound generating unit. The diaphragm is a component that is very sensitive to magnetic field changes. When an electrical signal passes through a coil, the magnetic field changes, causing the force on the diaphragm to change and the diaphragm to deform. Because the electrical signal changes very quickly, the diaphragm vibrates at a high speed; thus, the vibration of the diaphragm is transmitted to the air, generating sound waves.

[0003] During product assembly, the diaphragm needs to be bonded to the voice coil and the upper edge of the speaker frame. The existing method of assembling the earphone diaphragm to the diaphragm bracket is to first apply glue to the earphone diaphragm with a diaphragm ear, so that the earphone diaphragm adheres to the diaphragm bracket first, and then perform laser welding treatment through a laser welding device. Although this method can weld the earphone diaphragm to the diaphragm bracket, it is necessary to remove the glue at the diaphragm ear after welding. Therefore, it will inevitably affect the efficiency of assembling and welding the earphone diaphragm. At the same time, if the cleaning is not thorough or the cleaning force is too large, it will cause unnecessary damage to the earphone diaphragm or the diaphragm bracket, thereby affecting the quality and accuracy of assembling and welding the earphone diaphragm. Summary of the Invention

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] The present invention is a welding device for assembling a communication earphone diaphragm, including a base box. A rotating disk is rotatably arranged on the upper surface of the base box, and a plurality of mounting holes are circumferentially and arrayedly formed through the rotating disk. A positioning tray is rotatably arranged in each mounting hole. The positioning tray is used to position and support the placed diaphragm bracket. A transfer and fitting mechanism is arranged directly above one of the mounting holes of the rotating disk. The transfer and fitting mechanism is used to transfer and fit the diaphragm body to be welded onto the diaphragm bracket that is positioned and supported. A laser welding mechanism is arranged on the left side of the transfer and fitting mechanism. The laser welding mechanism is used to weld the fitted diaphragm body to the diaphragm bracket. A driving and adsorption mechanism for driving the positioning tray to rotate is arranged below the rotating disk, and the driving and adsorption mechanism corresponds to the transfer and fitting mechanism up and down.

[0006] Furthermore, the cross-section of the mounting hole is trumpet-shaped, the cross-section of the positioning tray is trumpet-shaped, and an arc-shaped groove is formed downward at its center. A square block is formed at the bottom of the positioning tray, and the square block extends out of the lower surface of the rotating disk. An annular groove is formed on the upper hole wall of the trumpet-shaped mounting hole. A rotating ring is fixed on the outer circumferential surface of the positioning tray, and the rotating ring is rotatably supported in the annular groove.

[0007] Further, the transfer and bonding mechanism includes a cross beam frame, a lead screw, a support block, a portal block, a support rod, a tubular rod, a rubber suction cup, and an air guide hose. The upper surface of the horizontally arranged cross beam frame is suspended above the base box in the protective cover through a hydraulic cylinder, and a lead screw is rotatably arranged below the cross beam frame. A support block is sleeved on the lead screw through a lead screw nut, and a portal block is fixed to the lower surface of the support block. The lower surfaces of the vertical blocks on both sides of the portal block are connected to the vertical support rods. A tubular rod is inserted into the support rod, and the bottom end of the tubular rod is communicated with a rubber suction cup, and the top end of the tubular rod is communicated with the air guide hose. The rubber suction cup is located below the support rod.

[0008] Further, the transfer and bonding mechanism further includes a bonding disc, contact balls, an annular plug, a spring member, and an exhaust pipe. The bonding disc is located at the bottom end face of the support rod, and the diameter of the bonding disc is larger than the diameter of the diaphragm body and smaller than the outermost diameter of the diaphragm support. A plurality of contact balls are rotatably installed in a circumferential array on the outermost circle of the lower surface of the bonding disc. A concave cavity is formed upward on the bottom end face of the bonding disc, and the concave cavity corresponds to the rubber suction cup. The tubular rod is slidably inserted into the bonding disc and the support rod. An annular cavity is formed in the support rod, and an annular plug fixed to the tubular rod is hermetically slidably arranged in the annular cavity. The upper surface of the annular plug is connected to the top cavity wall of the annular cavity through a spring member. The top cavity wall of the annular cavity is communicated with an exhaust pipe, and the exhaust pipe extends out of the support rod.

[0009] Further, an avoidance groove is formed at a position corresponding to the welding head of the laser welding mechanism on the outer side surface of the outer circle of the bonding disc.

[0010] Further, the driving and adsorbing mechanism includes a cavity sleeve rod, a support plate, a cylinder assembly, a driven gear, and a driving gear. The cavity sleeve rod is located directly below one of the mounting holes, and a square jack is formed at the top end of the cavity sleeve rod. The square jack is inserted and matched with the square block. The bottom end of the cavity sleeve rod is rotatably sleeved with a support plate through a bearing. The other end of the support plate is supported on the stepped base box through a cylinder assembly. A driven gear is fixedly sleeved on the cavity sleeve rod, and the driven gear meshes with a driving gear on one side. The driven gear is located above the support plate.

[0011] Further, the driving and adsorbing mechanism includes an air guide pipe and a rubber square sleeve. An annular air cavity is formed inside the positioning tray, and a plurality of negative pressure air holes are formed on the cavity wall of the annular air cavity. The plurality of negative pressure air holes are located in the arc-shaped groove. The annular air cavity is communicated with the cavity sleeve rod through a flow hole formed inside the square block. The bottom end of the cavity sleeve rod is communicated with an air guide pipe. A rubber square sleeve is arranged in the square jack, and the rubber square sleeve is inserted and matched with the square block by mutual extrusion.

[0012] Further, the laser welding mechanism includes a frame assembly and a welding head. The frame assembly is disposed on the side of the rotating disk, and the welding head is inclinedly installed on the frame assembly. The welding head extends to the clearance groove and corresponds to the fitting diaphragm bracket and diaphragm body.

[0013] The present invention has the following beneficial effects:

[0014] Through the cooperation of the self-rotating positioning tray, the sliding transfer fitting mechanism and the driving adsorption mechanism, the positioning tray can position and support the placed diaphragm bracket. The transfer fitting mechanism can adsorb and transfer the diaphragm body precisely and fit it onto the lifted diaphragm bracket. The driving adsorption mechanism can drive the positioning tray to rotate self in the mounting hole, so that the rotating diaphragm bracket can precisely and stably drive the fitting diaphragm body to rotate synchronously, and then the diaphragm body can be precisely and stably assembled and welded onto the diaphragm bracket. It not only does not require first adhering the diaphragm body to the diaphragm bracket by means of dispensing and then performing the assembly and welding process, but also can improve the quality and precision of the assembly and welding of the earphone diaphragm.

[0015] By rolling a plurality of contact balls on the lower surface of the fitting disk, when the positioning tray drives the diaphragm bracket to rotate, at this time the diaphragm bracket will synchronously drive the fitting diaphragm body to rotate. Since the diaphragm body is in contact with the fitting disk through a plurality of rolling contact balls, when the fitting disk presses the diaphragm body onto the diaphragm bracket, it will not interfere with the rotation of the diaphragm bracket driving the diaphragm body for edge welding. At the same time, since the plurality of contact balls are attached to the edge of the diaphragm body, there will be no phenomenon of wrinkles or warping at the edge of the diaphragm body, and thus it will not affect the quality and precision of the welding of the diaphragm body on the diaphragm bracket.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0029] Please refer to Figures 1 - 8As shown in the figure, the present invention is a communication earphone diaphragm assembly and welding device, including a base box 1. A rotating disk 2 is rotatably arranged on the upper surface of the base box 1. A plurality of mounting holes 21 are formed through the rotating disk 2 in a circumferential array. A positioning tray 3 is rotatably arranged in each mounting hole 21. The positioning tray 3 is used for positioning and supporting the placed diaphragm bracket. A transfer and fitting mechanism 4 is arranged directly above one of the mounting holes 21 of the rotating disk 2. The transfer and fitting mechanism 4 is used for transferring and fitting the diaphragm body to be welded onto the diaphragm bracket supported by positioning. A laser welding mechanism 6 is arranged on the left side of the transfer and fitting mechanism 4. The laser welding mechanism 6 is used for welding the fitted diaphragm body to the diaphragm bracket. A driving and adsorption mechanism 5 for driving the positioning tray 3 to rotate is arranged below the rotating disk 2, and the driving and adsorption mechanism 5 corresponds to the transfer and fitting mechanism 4 vertically;

[0030] Specifically, in the present invention, a plurality of rotatable positioning trays 3 are arranged on the rotating disk 2, so that the positioning trays 3 can position and support the placed diaphragm brackets. The rotation of the rotating disk 2 can convey the successively placed and lifted diaphragm brackets to the laser welding mechanism 6 and the transfer and fitting structure. The transfer and fitting mechanism 4 will first adsorb and fix the diaphragm body to be welded located behind the rotating disk 2, and then transfer and fit it onto the diaphragm bracket supported and lifted above the positioning tray 3. At this time, the diaphragm body will be accurately fitted onto the diaphragm bracket. Then the driving and adsorption mechanism 5 will be connected to the positioning tray 3 to drive the positioning tray 3 to rotate in the mounting hole 21. At this time, the positioning tray 3 will also adsorb and fix the lifted diaphragm bracket, and then drive the diaphragm bracket to rotate synchronously. Then the welding head 62 of the laser welding mechanism 6 will continuously weld the edges of the rotating diaphragm bracket and the closely fitted diaphragm body. And the transfer and fitting mechanism 4 does not interfere with the laser welding of the edge where the diaphragm body is fitted to the diaphragm bracket by the welding head 62, and at the same time can always perform rolling contact positioning on the diaphragm body being welded, so that the rotating diaphragm bracket can accurately and stably drive the fitted diaphragm body to rotate synchronously, so that the diaphragm body can be accurately and stably assembled and welded onto the diaphragm bracket. It not only does not need to first adhere the diaphragm body to the diaphragm bracket by means of dotting glue and then perform assembly and welding treatment, but also can improve the quality and precision of the earphone diaphragm assembly and welding; when the diaphragm body and the diaphragm bracket are welded, at this time, the transfer and fitting mechanism 4 disengages from pressing and fitting the diaphragm body, and the welding head 62 of the laser welding mechanism 6 disengages from the corresponding positioning tray 3, and the driving and adsorption mechanism 5 disengages from the connection drive with the positioning tray 3. Then the rotation of the rotating disk 2 will drive the welded diaphragm bracket and diaphragm body to the transfer and clamping mechanism, take them out from the positioning tray 3. At the same time, the rotation of the rotating disk 2 will transfer the next diaphragm bracket to be welded to the laser welding mechanism 6. By repeating the above steps, the diaphragm body can be welded to the diaphragm bracket.

[0031] In this embodiment, the cross-section of the mounting hole 21 is trumpet-shaped, the cross-section of the positioning tray 3 is trumpet-shaped, and an arc-shaped groove 31 is formed downward at its center. A square block 32 is formed at the bottom of the positioning tray 3, and the square block 32 extends out of the lower surface of the rotating disk 2. An annular groove 22 is formed on the upper hole wall of the trumpet-shaped mounting hole 21. A rotating ring 33 is fixed on the outer circumferential surface of the positioning tray 3, and the rotating ring 33 is rotatably supported in the annular groove 22;

[0032] Specifically, the trumpet-shaped mounting hole 21 facilitates the installation and positioning of the trumpet-shaped positioning tray 3, so that the positioning tray 3 will not fall out of the mounting hole 21. The arc-shaped surface of the arc-shaped groove 31 has the same size as the arc-shaped surface of the diaphragm bracket to be assembled and welded, so that the diaphragm bracket can be accurately fitted into the arc-shaped groove 31 of the positioning tray 3 without tilting or shifting. The positioning tray 3 is rotatably supported in the annular groove 22 through the rotating ring 33, so that the positioning tray 3 can stably rotate in the mounting hole 21 without tilting or skewing.

[0033] In this embodiment, the transfer and fitting mechanism 4 includes a cross beam frame 41, a lead screw 42, a support block 43, a portal block 44, a support rod 45, a tubular rod 46, a rubber suction cup 47 and an air guide hose 48. The upper surface of the horizontally arranged cross beam frame 41 in the front and rear is suspended above the base box 1 in the protective cover through a hydraulic cylinder. A lead screw 42 is rotatably arranged below the cross beam frame 41. A support block 43 is sleeved on the lead screw 42 through a lead screw 42 nut, and a portal block 44 is fixed on the lower surface of the support block 43. The lower surfaces of the two vertical blocks of the portal block 44 are connected to the vertical support rod 45. A tubular rod 46 is inserted into the support rod 45. The bottom end of the tubular rod 46 is communicated with a rubber suction cup 47, and the top end of the tubular rod 46 is communicated with the air guide hose 48. The rubber suction cup 47 is located below the support rod 45;

[0034] Specifically, the servo motor fixed at the rear of the cross beam frame 41 will drive the lead screw 42 to rotate, and the support block 43 will drive the support rod 45 to slide horizontally back and forth through the portal block 44. When the rubber suction cup 47 slides to the rear side of the rotating disk 2, the suction force generated by the air guide hose 48 and the tubular rod 46 will adsorb and fix the diaphragm body to the lower part of the support rod 45 through the rubber suction cup 47. Then the lead screw 42 rotates in the reverse direction, driving the support rod 45 to move to one side of the laser welding mechanism 6 and aligning with the diaphragm bracket on the positioning tray 3. Then the piston rod of the hydraulic cylinder above the cross beam frame 41 extends, driving the diaphragm body adsorbed on the lower surface of the support rod 45 to be accurately fitted to the diaphragm bracket, realizing the accurate fitting of the diaphragm body to the diaphragm bracket, which is convenient for the welding head 62 to accurately assemble and weld the rotating diaphragm body and the diaphragm bracket.

[0035] In this embodiment, the transfer and bonding mechanism 4 further includes a bonding disc 49, contact balls 493, an annular plug 494, a spring member 495, and an exhaust pipe 496. The bonding disc 49 is located at the bottom end surface of the support rod 45, and the diameter of the bonding disc 49 is larger than the diameter of the diaphragm body and smaller than the outermost diameter of the diaphragm support. A plurality of contact balls 493 are rotatably installed in a circumferential array on the outermost circumference of the lower surface of the bonding disc 49. A concave cavity 491 is formed upward on the bottom end surface of the bonding disc 49, and the concave cavity 491 corresponds to the rubber suction cup 47. The tubular rod 46 is slidably inserted into the bonding disc 49 and the support rod 45. An annular cavity 451 is formed in the support rod 45, and an annular plug 494 fixed on the tubular rod 46 is hermetically and slidably arranged in the annular cavity 451. The upper surface of the annular plug 494 is connected to the top cavity wall of the annular cavity 451 through a spring member 495. The top cavity wall of the annular cavity 451 is communicated with an exhaust pipe 496, and the exhaust pipe 496 extends outside the support rod 45;

[0036] Specifically, when the support rod 45 continuously moves to the rear side of the rotating disk 2, at this time, the exhaust pipe 496 will introduce high-pressure gas into the annular cavity 451 above the annular plug 494, so that it drives the tubular rod 46 to slide downward in the tubular support rod 45 through the annular plug 494. At this time, the spring member 495 will be stretched, and at this time, the rubber suction cup 47 will be pushed out from the concave cavity 491. Then, when the support rod 45 slides to a suitable position, the suction force generated by the air guide hose 48 and the tubular rod 46 will adsorb and fix the diaphragm body through the rubber suction cup 47. Then, after the support rod 45 slides to directly above the positioning tray 3 after operation, at this time, the downward movement of the support rod 45 will drive the adsorbed diaphragm body to descend and precisely fit onto the diaphragm support of the positioning tray 3. When the diaphragm body fits onto the diaphragm support, at this time, the rubber suction cup 47 will disengage from the adsorption and fixation of the diaphragm body, and then the air pressure in the annular cavity 451 above the annular plug 494 will be pumped out. The elastic restoring force of the spring member 495 will drive the tubular rod 46 to slide upward. At this time, the rubber suction cup 47 will retract into the concave cavity 491. As the rubber suction cup 47 retracts, at this time, the support rod 45 continues to descend, which will drive the fitting plate 49 to descend, so that a plurality of rolling contact balls 493 will fit onto the edge of the diaphragm body. When the positioning tray 3 drives the diaphragm support to rotate, at this time, the diaphragm support will synchronously drive the fitted diaphragm body to rotate. Since the diaphragm body is in contact with the fitting plate 49 through a plurality of rolling contact balls 493, when the fitting plate 49 presses the diaphragm body onto the diaphragm support, it will not interfere with the diaphragm support driving the diaphragm body to rotate for edge welding. At the same time, since a plurality of contact balls 493 fit onto the edge of the diaphragm body, therefore, it will not cause wrinkles or warping at the edge of the diaphragm body, and thus will not affect the welding quality and welding accuracy of the diaphragm body on the diaphragm support; when the diaphragm body is completely welded to the diaphragm support, at this time, the support rod 45 slides upward to disengage from the pressing and fitting of the diaphragm body, and then slides to the rear side of the rotating disk 2 to continue to grab and transfer the diaphragm body to be welded. There is a certain gap between the tubular rod 46 below the annular plug 494 and the tube wall of the tubular support rod 45, so that it will not interfere with the normal sliding of the annular plug 494 in the annular cavity 451.

[0037] In this embodiment, an avoidance groove 492 is provided at a position corresponding to the welding head 62 of the laser welding mechanism 6 on the outer circumferential side of the fitting plate 49;

[0038] Specifically, the opening of the clearance groove 492 facilitates the welding head 62 to extend into the edge where the diaphragm bracket and the diaphragm body are mutually attached, realizing the precise assembly and welding of the diaphragm body and the diaphragm bracket. At the same time, when the fitting disc 49 presses the edge of the diaphragm body against the diaphragm bracket through a plurality of contact balls 493, at this time, the welding head 62 will first extend into the clearance groove 492 to weld the edges of the diaphragm body and the diaphragm bracket, and then the positioning tray 3 drives the welded diaphragm bracket and the diaphragm body to rotate synchronously, so as to precisely weld the edges in sequence.

[0039] In this embodiment, the driving and adsorbing mechanism 5 includes a cavity sleeve rod 51, a support plate 52, a cylinder assembly 53, a driven gear 54 and a driving gear 55. The cavity sleeve rod 51 is located directly below one of the mounting holes 21, and a square socket 511 is formed at the top end of the cavity sleeve rod 51. The square socket 511 is inserted and matched with the square block 32. The bottom end of the cavity sleeve rod 51 is rotatably sleeved with a support plate 52 through a bearing. The other end of the support plate 52 is supported on the stepped base box 1 through the cylinder assembly 53. A driven gear 54 is fixedly sleeved on the cavity sleeve rod 51, and the driven gear 54 meshes with the driving gear 55 on one side. The driven gear 54 is located above the support plate 52.

[0040] Specifically, when the rotating disc 2 drives the positioning tray 3 to rotate to directly above the cavity sleeve rod 51, at this time, the rotating disc 2 stops rotating. At this time, the piston rod of the cylinder assembly 53 extends and drives the cavity sleeve rod 51 to move vertically upward through the support plate 52, so that the square socket 511 is sleeved on the square block 32, and the two are inserted and matched with each other. Then, the corresponding servo motor on the driving gear 55 works, and the meshing driven gear 54 drives the cavity sleeve rod 51 to rotate, and further enables the positioning tray 3 to rotate self in the mounting hole 21. After the diaphragm body and the diaphragm bracket are welded, the piston rod of the cylinder assembly 53 contracts, the support plate 52 drives the cavity sleeve rod 51 to slide downward, the square block 32 is disengaged from the square socket 511, and the driven gear 54 and the driving gear 55 are disengaged from meshing, which facilitates the rotating disc 2 to drive the welded diaphragm body and the diaphragm bracket to rotate to the next process for processing.

[0041] In this embodiment, the driving and adsorbing mechanism 5 includes an air guide pipe 56 and a rubber square sleeve 57. An annular air cavity 34 is formed inside the positioning tray 3, and a plurality of negative pressure air holes 35 are formed on the wall of the annular air cavity 34. The plurality of negative pressure air holes 35 are located in the arc-shaped groove 31. The annular air cavity 34 is communicated with the cavity sleeve rod 51 through a flow hole formed inside the square block 32. The bottom end of the cavity sleeve rod 51 is communicated with the air guide pipe 56. A rubber square sleeve 57 is arranged in the square socket 511, and the rubber square sleeve 57 is inserted and matched with the square block 32 by extrusion.

[0042] Specifically, when the square socket 511 of the cavity sleeve rod 51 is sleeved on the square block 32, at this time, the rubber square sleeve 57 will be squeezed and sealed on the square block 32. At this time, air can be pumped into the cavity sleeve rod 51 through the air guide pipe 56, so that it acts on the annular air cavity 34 through the flow holes. Furthermore, a plurality of negative pressure air holes 35 will generate negative pressure in the arc-shaped groove 31, so as to accurately and stably adsorb and fix the fitting and lifting diaphragm bracket to the positioning tray 3. When the positioning tray 3 rotates selflessly in the mounting hole 21, the diaphragm bracket cannot rotate synchronously with the positioning tray 3, resulting in the welding head 62 being unable to perform precise laser welding treatment on the fitting diaphragm body and diaphragm bracket.

[0043] In this embodiment, the laser welding mechanism 6 includes a frame assembly 61 and a welding head 62. The frame assembly 61 is arranged on the side of the rotating disk 2, and the welding head 62 is inclinedly installed on the frame assembly 61. The welding head 62 extends into the clearance groove 492 to correspond to the fitting diaphragm bracket and diaphragm body. Specifically, the frame assembly 61 can adjust the fuselage of the laser welding machine, so that the welding head 62 can be inserted into the clearance groove 492 obliquely to achieve precise laser welding treatment on the continuously and slowly rotating diaphragm bracket and diaphragm body.
