Description

Technical Field

[0001] The present invention relates to a fully automatic coil and diaphragm combination scribing machine. Background Art

[0002] A coil and diaphragm combination scribing machine (i.e., a bonding machine for the lead wire of the speaker coil and the diaphragm) is an automated machine that bonds the lead wire of the speaker coil (in a certain arc shape) to the speaker diaphragm with glue. The front of this station is connected to a coil and diaphragm combination machine. For example, after the production of a device with the application number 201620263121X and the patent name "A Device for Assembling and Bonding a Coil and a Diaphragm" is completed, the next automated machine in the speaker production process is the coil and diaphragm combination scribing machine.

[0003] Among them, the equipment for bonding the coil and the diaphragm with glue has been successfully developed, that is, the device with the application number 201620263121X and the patent name "A Device for Assembling and Bonding a Coil and a Diaphragm". However, the research and development of bonding the lead wire of the speaker coil to the diaphragm with glue has not been broken through. The main reasons are as follows:

[0004] (1) Difficulty in grasping the lead wire of the speaker coil:

[0005] During the scribing process of the coil and diaphragm combination, since the lead wire of the speaker coil is erratic, it is very difficult to position the lead wire of the speaker coil, resulting in the inability to achieve fully automatic sorting and grasping of the lead wire of the speaker coil.

[0006] (2) Difficulty in achieving consistency in the folding line trajectory of the lead wire of the speaker coil:

[0007] After one end of the lead wire of the speaker coil is fixed on the diaphragm, glue application and scribing need to be carried out. Since the other end of the lead wire is a free end and the lead wire has the characteristic of being erratic, it is very difficult to position the lead wire before glue application and scribing. In addition, in the actual production process, it is very difficult to form the shape of the lead wire of the speaker coil. Often, due to reasons such as the middle of the lead wire of the speaker coil spreading apart or rebounding, the shape forming of the lead wire is unstable. Therefore, in the prior art, manual methods are used to position the lead wire, or the lead wire is controlled at the beginning of winding, and it is impossible to position the lead wire separately before glue application and scribing.

[0008] (3) Difficulty in positioning the lead wire of the speaker coil:

[0009] After one end of the lead wire of the speaker coil is fixed on the diaphragm, glue application and scribing need to be carried out. Since the other end of the lead wire is a free end and the lead wire has the characteristic of being erratic, it is very difficult to position the lead wire before glue application and scribing. Therefore, in the prior art, manual methods are used to position the lead wire, or the lead wire is controlled at the beginning of winding, and it is impossible to position the lead wire separately before glue application and scribing.

[0010] Due to the above technical bottlenecks, the production capacity of the combination scribing of the voice coil and diaphragm is insufficient, unable to meet the requirements of fully automated production. Summary of the Invention

[0011] In view of the above problems, the present invention provides a fully automatic voice coil and diaphragm combination scribing machine, which can realize the fully automated production of the bonding of the lead wire of the speaker voice coil and the diaphragm; further, it realizes the full-automatic sorting and grasping of the lead wire of the speaker voice coil during the combination scribing process of the voice coil and diaphragm, improving the sound quality of the speaker; further, it realizes the full-automatic folding of the lead wire of the voice coil during the combination scribing process of the voice coil and diaphragm, preparing the path trajectory for glue application and scribing; further, it clamps and positions the free end of the lead wire of the speaker voice coil to achieve a better processing effect.

[0027] Preferably, a pressing fixture cylinder is also arranged on the support plate. The pressing fixture cylinder drives the fixture fixing cover to move up and down.

[0028] Preferably, a first adsorption mechanism capable of exhausting air is arranged at the bottom of the multi-functional fixture. A gas channel communicating with the first adsorption mechanism is arranged vertically through the multi-functional fixture from top to bottom.

[0031] Preferably, a rotating shaft sleeve is sleeved on the outer periphery of the rotating shaft. The rotating shaft positioning pin and the limiting block are arranged inside the rotating shaft sleeve. The second top block extends to the outside of the rotating shaft sleeve.

The wire clamping rubber cap and the wire clamping guide block are used for clamping the free end of the lead wire of the speaker voice coil.

[0033] Preferably, the wire clamping mechanism includes symmetrically arranged "L"-shaped grippers.

An upper and lower wire pressing cover air cylinder mechanism is further arranged on the support frame. A wire pressing cover for pressing down the lead wire of the speaker voice coil is arranged at the bottom of the upper and lower wire pressing cover air cylinder mechanism.

[0034] The beneficial effects of the present invention are:

[0035] First, the fully automatic voice coil and sound membrane combination scribing machine provided by the present invention can realize the fully automated production of bonding the speaker voice coil lead wire and the sound membrane, reduce labor costs, increase the consistency and stability of the broken line trajectory during the voice coil and sound membrane combination scribing process, and improve the voice coil and sound membrane combination scribing work efficiency.

[0036] Secondly, the device for arranging the speaker voice coil lead wires solves the problem of fully automatic arranging and positioning the speaker voice coil lead wires during the process of marking the voice coil and sound membrane combination, so that the position of the speaker voice coil lead wires can be found during marking. Among them, the upper and lower wire pressing cover cylinder mechanisms realize the contraction and retraction of the speaker voice coil lead wires in the upper and lower directions, and the wire organizing and clamping cylinder mechanisms realize the contraction and retraction of the speaker voice coil lead wires in the horizontal direction, thereby realizing the arranging of the speaker voice coil lead wires, and finally realizing fully automatic arranging and positioning of the speaker voice coil lead wires, reducing labor costs, increasing the stability of the voice coil and sound membrane combination marking process, improving the efficiency of the voice coil and sound membrane combination marking work, and improving the sound quality of the speaker.

[0037] Third, the folding device drives the sound film / voice coil assembly and the lead wire to rotate through the rotation of the folding shaft and the first folding pressure head, so that the outer surface of the folding shaft drives the lead wire to bend to obtain the required folding trajectory, and prepares the folding trajectory for the next station to mark and glue. The fully automatic folding trajectory in the process of marking and gluing the voice coil and sound film assembly is realized, which reduces labor costs, increases the stability of the voice coil and sound film assembly marking process, and improves the work efficiency of the voice coil and sound film assembly marking.

[0038] Fourth, before fully automatic folding, use the speaker voice coil lead wire positioning and clamping device to position and clamp the free end of the voice coil lead wire. Specifically, place the speaker sound membrane in the jig. After the front workstation has arranged the lead wire, you can first push the wire clamp rubber cap upward by moving the opening mechanism to open the wire clamp rubber cap, and place the lead wire between the wire clamp rubber cap and the wire clamp guide block. After the adsorption mechanism moves upward, it starts to vacuum so that the speaker sound membrane is adsorbed in the jig, and the opening mechanism moves downward. The lead wire is clamped between the wire clamp rubber cap and the wire clamp guide block. At this point, the positioning and clamping action of the lead wire is completed, which effectively solves the positioning of the lead wire during the marking process of the voice coil and sound membrane combination, so that the lead wire can be accurately positioned during marking.

Detailed implementation manners

[0064] The technical solutions of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments given are not intended to limit the present invention.

[0065] As Figure 1As shown in the figure, a fully automatic voice coil and voice diaphragm combination scribing machine includes a workbench 47 and a feeding mechanism 36. A rotatable turntable 48 is arranged on the workbench 47. At least one multifunctional fixture for placing products to be processed is arranged on the turntable 48. Three to eight multifunctional fixtures can also be arranged. Each multifunctional fixture can be evenly arranged on the circular turntable 48. By rotating the circular turntable 48 by one station, the products to be processed can be driven to flow to the corresponding stations for relevant processing. Therefore, a device for arranging the lead-out wires of the speaker voice coil 37, a positioning and clamping device 38, a wire bending device 39, a first gluing mechanism, a first air blowing mechanism 41, a shaping mechanism 42, a second gluing mechanism, a second air blowing mechanism 44 and a blanking mechanism 45 are sequentially arranged along the periphery of the turntable 48. Each time the turntable 48 rotates by one station (that is, the stations corresponding to the devices marked 37 - 45 in the attached Figure 1 ), each multifunctional fixture can flow from the current station to the next station.

[0066] Figure 1 In the figure, in order to fully show the front stations and subsequent stations of the fully automatic voice coil and voice diaphragm combination scribing machine, the voice coil and voice diaphragm combination scribing machine 33 and the drying and turnover device 35 are also shown. The voice coil and voice diaphragm combination scribing machine 33 bonds the voice coil and the voice diaphragm together with glue. The products to be processed are placed on the drying and turnover device 35 through the turnover and feeding mechanism 34 for drying the speaker glue. After drying, the feeding mechanism 36 moves the products to be processed to the device for arranging the lead-out wires of the speaker voice coil 37.

[0067] The device for arranging the lead-out wires of the speaker voice coil 37 is used for fully automatically arranging the lead-out wires of the speaker voice coil. As Figures 2-5 shown, the fully automatic device for arranging the lead-out wires of the speaker voice coil includes a support frame 61. A front and rear material taking cylinder mechanism 49 that can move horizontally is arranged on the support frame 61. Figure 2 In the attached figure, the label 50 corresponds to the front, and the label 49 corresponds to the rear. The front and rear material taking cylinder mechanism 49 can adopt the air cylinder structure of AirTAC MA20x180SU. Then, the front and rear material taking cylinder mechanism 49 moves forward to take materials and moves backward to place materials. Preferably, a speed regulating valve 57 is arranged on the front and rear material taking cylinder mechanism 49, and the moving speed of the front and rear material taking cylinder mechanism 49 can be adjusted to adapt to different production lines.

[0068] A vertically movable up-and-down material taking servo mechanism 50 is provided at the front end of the front-and-rear material taking cylinder mechanism 49. Correspondingly, a linear module 62 is provided on the up-and-down material taking servo mechanism 50, and the up-and-down material taking servo mechanism 50 moves up and down along the linear module 62. Preferably, the up-and-down material taking servo mechanism 50 is a servo-driven module moving mechanism. For example, a linear module of model KR2006A-0030-H0-00AQ of THK is adopted. A vacuum suction nozzle 58 capable of adsorbing the speaker diaphragm is provided at the bottom of the up-and-down material taking servo mechanism 50. By the horizontal movement of the front-and-rear material taking cylinder mechanism 49 and the vertical movement of the up-and-down material taking servo mechanism 50, the vacuum suction nozzle 58 can be positioned directly above the diaphragm.

[0069] As Figure 4 shown, preferably, a five-in-one feeding mechanism 59 is provided at the material taking station. A plurality of cavities for placing the speaker diaphragms are provided on the five-in-one feeding mechanism 59. Figure 4 In (in order to reduce the handling time, 5 workpieces to be processed are concentrated and placed on the five-in-one feeding mechanism. During specific processing, each workpiece to be processed is taken out separately in sequence), a first through hole is provided at the center of each cavity. Since the diaphragm has been at the bottom of the fixture of the five-in-one feeding mechanism 59, simply relying on the vacuum suction nozzle 58 of the up-and-down material taking servo mechanism 50 cannot ensure that the diaphragm can be taken away. Therefore, a jacking mechanism 53 for jacking up the diaphragm is provided at a set distance below the vacuum suction nozzle 58. A material taking station is formed between the vacuum suction nozzle 58 and the jacking mechanism 53. The jacking mechanism 53 can also adopt a cylinder structure, and a vacuum suction nozzle is provided at its top to jack up the diaphragm.

[0070] Directly above the cavity corresponds to the vacuum suction nozzle 58 and directly below corresponds to the jacking mechanism 53. The vacuum suction nozzle corresponding to the top of the jacking mechanism 53 can penetrate the first through hole to jack up the diaphragm. The lead-out wire of the speaker voice coil of the diaphragm may be crooked. After the diaphragm is jacked up and the lead-out wire of the speaker voice coil is clamped and pulled, the lead-out wire of the speaker voice coil of the diaphragm becomes straight. Then, the vacuum of the vacuum suction nozzle at the top of the jacking mechanism 53 is broken, and the vacuum suction nozzle 58 of the upper up-and-down material taking servo mechanism 50 sucks away the diaphragm.

[0071] A brush 60 is provided on one side of the five-in-one feeding mechanism 59 close to the lead-out wire of the speaker voice coil. Figure 4In it, a row of brushes 60 is added to the right side of the five-in-one feeding mechanism 59 to prevent the lead wire of the speaker voice coil from sagging. A front and rear wire arranging cylinder mechanism 54, a wire arranging and clamping cylinder mechanism 55 and a wire clamping mechanism 56 for clamping the lead wire of the speaker voice coil are further arranged on the support frame 61. The wire clamping mechanism 56 realizes horizontal movement through the front and rear wire arranging cylinder mechanism 54 and realizes clamping of the lead wire of the speaker voice coil through the wire arranging and clamping cylinder mechanism 55. For example, the wire arranging and clamping cylinder mechanism 55 is a finger cylinder, and the front and rear wire arranging cylinder mechanism 54 is a slide table cylinder. Speed control valves 57 are arranged on both the finger cylinder and the slide table cylinder.

[0072] Due to the particularity of the lead wire of the speaker voice coil, preferably, the wire clamping mechanism 56 includes symmetrically arranged "L"-shaped grippers. Figure 4 In it, the rear ends of the two "L"-shaped grippers are close together, and the front ends are open. The wire arranging and clamping cylinder mechanism 55 drives the two grippers to close inward to clamp the lead wire of the speaker voice coil.

[0073] Preferably, an upper and lower wire pressing cover cylinder mechanism 51 is further arranged on the support frame 61. A wire pressing cover 52 for pressing down the lead wire of the speaker voice coil is arranged at the bottom of the upper and lower wire pressing cover cylinder mechanism 51. For example, a second through hole is arranged in the center of the wire pressing cover 52, and the bottom of the upper and lower material taking servo mechanism 50 penetrates through the second through hole by a set distance. Figure 3 As shown, the wire pressing cover 52 is higher than the vacuum suction nozzle 58 by a certain height. The lead wire of the speaker voice coil can be pressed down by the wire pressing cover 52. Among them, the upper and lower wire pressing cover cylinder mechanism 51 can be a slide table cylinder. For example, AirTAC TACQ12X20S. A speed control valve 57 is also arranged on the upper and lower wire pressing cover cylinder mechanism 51.

[0074] During specific scribing, the five-in-one feeding mechanism 59 (the five-in-one mechanism in the figure) moves to the material taking station. The front and rear material taking cylinder mechanism 49 moves forward, the upper and lower material taking servo mechanism 50 moves downward, and the upper and lower wire pressing cover cylinder mechanism 51 moves downward to press down the lead wire of the speaker voice coil. At the same time, the speaker diaphragm is lifted upward by the lifting mechanism 53, sucks the speaker diaphragm from below the speaker diaphragm. The front and rear wire arranging cylinder mechanism 54 moves forward, the wire arranging and clamping cylinder mechanism 55 clamps the wire and takes it in. Then the front and rear wire arranging cylinder mechanism 54 moves backward to arrange the wire. After that, after the vacuum of the vacuum suction cup on the lifting mechanism 53 is broken for the speaker diaphragm, the vacuum suction nozzle 58 on the upper and lower material taking servo mechanism 50 takes the material. The upper and lower wire pressing cover cylinder mechanism 51 moves upward, the upper and lower material taking servo mechanism 50 moves upward, and the front and rear material taking cylinder mechanism 49 moves backward to place the product on the large disc loading fixture station. After the speaker diaphragm is positioned, the wire arranging and clamping cylinder mechanism 55 is opened to complete the action of arranging the lead wire of the speaker voice coil during the scribing process of the voice coil and speaker diaphragm combination.

[0075] The device 37 for arranging the lead wires of the speaker voice coil solves the problem of positioning the lead wires of the speaker voice coil during full-automatic arrangement, enabling the position of the lead wires of the speaker voice coil to be found during scribing. Among them, the upper and lower pressing cover cylinder mechanism realizes the closing of the lead wires of the speaker voice coil in the up and down direction, and the wire arranging and clamping cylinder mechanism realizes the closing of the lead wires of the speaker voice coil in the horizontal direction, thus realizing the arrangement of the lead wires of the speaker voice coil, and finally realizing the full-automatic positioning of the lead wires of the speaker voice coil, reducing labor costs, increasing the stability of the scribing process of the voice coil and diaphragm assembly, improving the working efficiency of the scribing of the voice coil and diaphragm assembly, and improving the sound quality of the speaker.

[0076] The positioning and clamping device 38 is used to position and clamp the free end of the voice coil lead wire, as Figures 15-20 shown. The speaker voice coil lead wire positioning and clamping device 38 includes a multi-functional jig 5, that is, the multi-functional jig 5 on the turntable 48 is a part of the speaker voice coil lead wire positioning and clamping device 38. In order to more conveniently understand the function of the multi-functional jig 5 at the positioning and clamping station, this part mainly introduces the structure related to the multi-functional jig 5 and the positioning and clamping place. Specifically, the multi-functional jig includes a jig body 64 for placing the speaker diaphragm 75, and also includes a wire clamping seat 65 arranged on the outer periphery of the jig body 64. A second adsorption mechanism 71 (i.e., at the positioning and clamping station, the second adsorption mechanism 71 is arranged at the bottom of the multi-functional jig 5), such as a vacuum pumping mechanism, is arranged at the bottom of the jig body 64. A gas passage communicating with the second adsorption mechanism 71 runs through the jig body 64 from top to bottom. When the diaphragm is placed in the jig body 64, the cavity between the diaphragm and the jig body 64 can be evacuated through the second adsorption mechanism 71 to adsorb the diaphragm in the jig body 64, forming a fixing effect. Preferably, a jig seat 63 is arranged at the bottom of the jig body 64, and the wire clamping seat 65 is connected to the jig seat 63.

[0077] A through hole is arranged on the wire clamping seat 65. A wire clamping guide block 66 runs through the through hole from top to bottom on one side, and an L-shaped fixture connecting rod 76 is arranged on the other side of the through hole. One end of the fixture connecting rod 76 is arranged on the wire clamping seat 65 through a spring 70, and the other end of the fixture connecting rod 76 is provided with a wire clamping rubber cap 68. The wire clamping rubber cap 68 is arranged between the fixture connecting rod 76 and the wire clamping guide block 66. Preferably, the wire clamping rubber cap 68 and the fixture connecting rod 76 are arranged on the wire clamping seat 65 through a positioning pin 67, and the wire clamping rubber cap 68 and the fixture connecting rod 76 can be linked.

[0078] The positioning and clamping device 38 can manually move the wire clamping rubber cap 68 away from or close to the wire clamping guide block 66, or can also be fully automatic. For the fully automatic implementation scheme, an opening mechanism 72 needs to be arranged below the wire clamping rubber cap 68. A third cylinder 73 is arranged at the bottom of the opening mechanism 72. The third cylinder 73 drives the opening mechanism 72 to move up and down to push the wire clamping rubber cap 68 away from or close to the wire clamping guide block 66.

[0079] by Figure 15 Taking the direction as an example, when the opening mechanism 72 pushes the wire clamp rubber cap 68 upward, the top of the wire clamp rubber cap 68 and the clamp connecting rod 76 tilt toward the spring 70, and the distance between the wire clamp rubber cap 68 and the wire clamping guide block 66 increases; when the opening mechanism 72 moves downward to disengage from the wire clamp rubber cap 68, the wire clamp rubber cap 68 and the clamp connecting rod 76 are reset under the action of the spring 70, and the wire clamp rubber cap 68 is tightly attached to the wire clamping guide block 66, and the wire clamp rubber cap 68 and the wire clamping guide block 66 are used to clamp the free end of the speaker voice coil lead wire.

[0080] Preferably, the top of the opening mechanism 72 is a pointed top block 77, which makes it easier to open the wire clamp rubber cap 68 during the upward movement. Since the free end of the lead wire is delicate, it is best to provide a wire stop shaft 69 in the through hole to prevent the voice coil lead wire from sagging. Figure 16 In the figure, the wire clamp rubber cap 68 is a cylindrical silicone cap, and a concave groove matching the wire clamp rubber cap 68 is provided on one side of the wire clamp guide block 66 close to the wire clamp rubber cap 68, so that even very thin and soft lead wires can be clamped. Figure 18 In the embodiment, a fourth cylinder 74 is provided at the bottom of the second adsorption mechanism 71, and the fourth cylinder 74 drives the second adsorption mechanism 71 to move up and down close to or away from the fixture seat 63. When positioning and clamping are required, the second adsorption mechanism 71 moves upward close to the fixture seat 63, and then performs a vacuum operation.

[0081] Before the fully automatic folding, the speaker voice coil lead wire positioning and clamping device is first used to position and clamp the free end of the voice coil lead wire. Specifically, the speaker sound membrane is placed in the jig body 64. After the lead wire is arranged in the front station, the wire clamp rubber cap 68 can be pushed upward by the opening mechanism 72 to move the wire clamp rubber cap 68 so that the wire clamp rubber cap 68 opens, and the lead wire is placed between the wire clamp rubber cap 68 and the wire clamping guide block 66. After the second adsorption mechanism 71 moves upward, it starts to vacuum so that the speaker sound membrane is adsorbed in the jig body 64. The opening mechanism 72 moves downward, and the lead wire is clamped between the wire clamp rubber cap 68 and the wire clamping guide block 66. At this point, the positioning and clamping action of the lead wire is completed, which effectively solves the positioning of the lead wire during the marking process of the voice coil and sound membrane combination, so that the lead wire can be accurately positioned during marking.

[0082] The folding device 39 is used to automatically fold the speaker voice coil lead wire to prepare a path track for glue marking. Figures 6-14 As shown, the folding device 39 of the speaker voice coil lead wire includes a support plate 11. The folding device can be fixed on the whole machine through the support plate 11. The support plate 11 is equivalent to the supporting component of the device. The support plate 11 is provided with an upper and lower servo mechanism 1 to Figure 6Taking the [direction] as an example, a vertical servo mechanism 1 is provided at the top of the support plate 11. The bottom of the vertical servo mechanism 1 is connected to an upper rotary servo 2, and the vertical servo mechanism 1 drives the upper rotary servo 2 to move up and down. The vertical servo mechanism 1 can adopt structures such as a linear module or a cylinder that can perform linear motion.

[0083] The bottom of the upper rotary servo 2 is connected to an upper rotary jig 10, and the upper rotary servo 2 drives the upper rotary jig 10 to perform a rotary motion. Below the upper rotary jig 10 can be directly opposite to the multi-functional jig 5 (when the multi-functional jig 5 is at the positioning and clamping station, it has the function of positioning and clamping; when the multi-functional jig 5 is at the folding line station, it has the function of rotating). A cavity for placing the speaker diaphragm is formed between the upper rotary jig 10 and the multi-functional jig 5, and the lead-out wire of the voice coil is shaped by the synchronous rotation of the upper rotary jig 10 and the multi-functional jig 5.

[0084] Preferably, a press jig cylinder 8 is further provided on the support plate 11. The press jig cylinder 8 drives the jig fixing cover 6 to move up and down. The jig fixing cover 6 is sleeved outside the upper rotary jig 10 and is located above the multi-functional jig 5. The jig fixing cover 6 drives the multi-functional jig 5 to move up and down. For example, Figure 14 As a specific embodiment of the related structure of the press jig cylinder 8, among them, the press jig cylinder 8 is a second slide cylinder 30, the jig fixing cover 6 is a pressing plate 29, and the pressing plate 29 is provided with a through hole for sleeving outside the upper rotary jig 10.

[0085] To more conveniently understand the function of the multi-functional jig 5 at the folding line station, this part mainly introduces the structure related to the multi-functional jig 5 and the folding line. In order to achieve stable rotation, preferably, a first adsorption mechanism 15 that can extract air is provided at the bottom of the multi-functional jig 5 (that is, at the folding line station, the first adsorption mechanism 15 is provided at the bottom of the multi-functional jig 5), such as Figure 11 As shown, the first adsorption mechanism 15 can be a vacuum extraction device. The multi-functional jig 5 is provided with a gas passage communicating with the first adsorption mechanism 15 from top to bottom. A second cylinder 14 is provided at the bottom of the first adsorption mechanism 15. The second cylinder 14 drives the first adsorption mechanism 15 to approach or move away from the multi-functional jig 5. The first adsorption mechanism 15 can be located directly below the gas passage. When folding the line, the second cylinder 14 drives the first adsorption mechanism 15 to approach the multi-functional jig 5, and the first adsorption mechanism 15 performs a vacuum extraction operation. After the folding line is completed, the second cylinder 14 drives the first adsorption mechanism 15 to move away from the multi-functional jig 5. The second cylinder 14 can adopt structures such as a linear module or a cylinder that can perform linear motion.

[0086] The multi-functional jig 5 is a device for placing the diaphragm / voice coil assembly, and its overall structure is as Figure 9 shown, and the cross-sectional view is as Figure 10As shown in the figure, specifically, the multifunctional fixture 5 further includes a wire clamping seat disposed on the outer periphery of the multifunctional fixture 5 for clamping the free end of the lead wire of the speaker voice coil. A rotating shaft 17 is provided at the center of the multifunctional fixture 5, and the center of the rotating shaft 17 is a hollow gas passage. The gas passage communicates with the upper and lower end faces of the multifunctional fixture 5. The top cavity of the multifunctional fixture 5 is evacuated by the first adsorption mechanism 15.

[0087] The multifunctional fixture 5 is further provided with a rotating shaft positioning pin 19. A limiting block 20 is provided at the bottom of the rotating shaft positioning pin 19. When the rotating shaft positioning pin 19 and the limiting block 20 are engaged together, the rotating shaft 17 cannot rotate. Only when the two are completely separated can the rotating shaft 17 rotate. A first compression spring 18 is provided at the top of the rotating shaft positioning pin 19. The rotating shaft positioning pin 19 is connected to a second top block 13. A first cylinder 3 is further provided below the multifunctional fixture 5. The first cylinder 3 can adopt structures such as a linear module or a cylinder that can perform linear motion. Figure 10 Taking a specific embodiment as an example, by default, the limiting block 20 is pressed down by the first compression spring 18 and the rotating shaft positioning pin 19, and the inner fixture 32 at the bottom of the limiting block 20 is locked, and the rotating shaft 17 is automatically locked and cannot rotate. Only under the action of an external force, the limiting block 20 is opened through the second top block 13, and the rotating shaft positioning pin 19 and the limiting block 20 can be separated, that is, the first cylinder 3 is connected to a first top block 4 located below the second top block 13. The first cylinder 3 drives the first top block 4 to move up and down, thereby driving the second top block 13 to move up and down, thereby driving the rotating shaft positioning pin 19 to disengage or engage with the limiting block 20. The inner fixture 32 fixed on the rotating shaft 17 can perform a rotating operation, and the inner fixture 32 drives the rotating shaft 17 to perform a rotating operation.

[0088] Preferably, a rotating shaft sleeve 16 is sleeved on the outer periphery of the rotating shaft 17. The rotating shaft positioning pin 19 and the limiting block 20 are disposed inside the rotating shaft sleeve 16. The second top block 13 extends to the outside of the rotating shaft sleeve 16. Among them, the rotating shaft 17 can rotate, and the rotating shaft sleeve 16 does not rotate. When folding, the rotating shaft 17 is in a rotating state, and the rotating shaft sleeve 16 is in a fixed state. The rotating shaft positioning pin 19 and the limiting block 20 disposed inside the rotating shaft sleeve 16 are used to control whether the rotating shaft 17 can perform a free rotating motion.

[0089] Preferably, the top cavity of the multifunctional fixture 5 has a shape that is larger at the top and smaller at the bottom, and a return spring is provided on the rotating shaft sleeve 16. The cavity of the multifunctional fixture 5 has a shape that is larger at the top and smaller at the bottom. When the sound membrane is located at the upper position of the cavity, the sound membrane can rotate; when the sound membrane is located at the lower position of the cavity, the sound membrane can be fixed. Therefore, when the sound membrane is pressed down, it can be fixed, and when the return spring 31 rebounds, the sound membrane can rotate. The fixture fixing cover moves upward to fix the sound membrane / voice coil assembly (also called the sound membrane). Figure 10 andFigure 14 Taking the structure as an example, when the pressing plate 29 moves downward, the upper rotating jig 10 moves downward to fix the sounding film. After the pressing plate 29 is released upward, the return spring 31 bounces back, the upper rotating jig 10 moves upward, and the sounding film is in a rotatable state.

[0090] As Figure 13 shown, the upper rotating jig 10 includes a second folding line press head 27 and a first folding line press head 12 arranged from top to bottom. A set distance is set between the second folding line press head 27 and the first folding line press head 12. The upper rotating jig 10 further includes a plurality of pin gauges 9 (i.e., guide shafts) passing through the second folding line press head 27 and the first folding line press head 12. Figure 13 In [description], the number of the pin gauges 9 is 3. Preferably, the pin gauges 9 are cylindrical, which can be folded into an arc without damaging the lead wires. The top of the pin gauge 9 is arranged on the second folding line press head 27 through a second compression spring 25 and a bush shaft 26.

[0091] A draw wire shaft cylinder 7 is further arranged at the bottom of the upper rotating servo 2. A core-pulling plate 22 is arranged at the bottom of the draw wire shaft cylinder 7. The core-pulling plate 22 is placed between the second folding line press head 27 and the first folding line press head 12. As Figure 12 shown, a semi-circular notch 24 is arranged at one end of the core-pulling plate 22 away from the draw wire shaft cylinder 7 for inserting between the second folding line press head 27 and the first folding line press head 12. The up and down movement of the draw wire shaft cylinder 7 drives the up and down movement of the core-pulling plate 22, and then drives the pin gauge 9 to disengage from or embed into the cavity of the multi-functional jig 5.

[0092] To improve the processing accuracy, preferably, the upper rotating jig 10 further includes a draw wire shaft 28. The draw wire shaft 28 passes through the second folding line press head 27 and the first folding line press head 12. Among them, the draw wire shaft 28 can be pressed back. It is a core-pulling shaft. It is a stop shaft when folding the line and a core-pulling shaft when core-pulling. Core-pulling is to release the stress of the elastic force generated by the draw wire shaft. Taking Figure 12 and Figure 13 the structure as an example, when core-pulling, it is realized by the first sliding table cylinder 23 and the core-pulling plate 22. Among them, the core-pulling plate 22 drives the second folding line press head 27 to move upward. The draw wire shaft 28 is locked on the second folding line press head 27. After the core-pulling plate 22 moves downward and is released, the second compression spring 25 bounces back. Figure 12 In [description], the draw wire shaft cylinder 7 is the first sliding table cylinder 23. The draw wire shaft cylinder 7 is fixed on the upper rotating servo 2 through a cylinder fixing plate 21.

[0093] Before gluing and marking, the speaker voice coil lead wire can be automatically folded by the folding device to prepare the path trajectory for gluing and marking. After the diaphragm / voice coil assembly is moved to the folding station (that is, the diaphragm / voice coil assembly is placed in the cavity of the multifunctional jig, and the free end of the lead wire is clamped by the clamping seat), the upper and lower servo mechanisms move downward to drive the upper rotating servo to move downward synchronously. After the first folding pressure head presses the diaphragm / voice coil assembly, the first cylinder moves upward to push the second top block open, and the self-locking components (rotating shaft positioning pin and limit block) of the multifunctional jig are disengaged, and the multifunctional jig can rotate without obstacles; and the gear-drawing wire shaft cylinder moves downward, and the gear-drawing wire shaft penetrates into the cavity of the multifunctional jig and contacts the lead wire. At this time, the jig cylinder moves downward, the upper rotating servo rotates, and the first folding pressure head rotates to bend the required arc of the voice coil lead wire. During the folding process, the first adsorption mechanism can be used to perform a vacuum operation so that the diaphragm / voice coil assembly is stably adsorbed in the jig, and the upper rotating jig 10 and the multifunctional jig 5 rotate synchronously. Since the free end of the lead wire is clamped by the wire clamping seat, the lead wire does not rotate synchronously during rotation, but the lead wire at the diaphragm end rotates, and the lead wire is blocked by the withdrawal wire shaft 28, so that the required shape can be folded by rotation.

[0094] After completion, the pressing jig cylinder moves upward, the jig fixing cover moves upward to fix the diaphragm / voice coil assembly (also called the diaphragm), the withdrawal spool cylinder moves upward, so that the withdrawal spool is separated from the speaker voice coil lead wire, the upper rotating mechanism releases the diaphragm / voice coil assembly, and the upper and lower servo mechanisms drive the upper rotating mechanism to move upward. At this point, the entire device rotates to complete the lead wire shape forming action.

[0095] The rotation of the folding shaft and the first folding pressure head drives the sound film / voice coil assembly and the lead wire to rotate, so that the outer surface of the folding shaft drives the lead wire to bend to obtain the required folding trajectory, and prepares the folding trajectory for the next station to mark and glue. The fully automatic folding trajectory in the process of marking and gluing the voice coil and sound film assembly is realized, which reduces labor costs, increases the stability of the voice coil and sound film assembly marking process, and improves the work efficiency of the voice coil and sound film assembly marking.

[0096] The first glue - applying mechanism is used for dot - gluing the voice - coil lead - out wire and the voice diaphragm, and a two - dimensional glue - applying mechanism 40 (a glue - applying machine that can move in the X - direction and Y - direction) can be adopted. The first air - blowing mechanism 41 is used for blowing air to initially dry the glue. The shaping mechanism 42 is used to press the voice - coil lead - out wire and the voice diaphragm so that the voice - coil lead - out wire fits the voice diaphragm. The second glue - applying mechanism is used for scribing glue on the voice - coil lead - out wire and the voice diaphragm, and a three - dimensional glue - applying mechanism 43 (a glue - applying machine that can move in the X - direction, Y - direction, and Z - direction) can be adopted. The second air - blowing mechanism 44 is used for blowing air to further dry the glue. The first air - blowing mechanism 41 and the second air - blowing mechanism 44 can adopt a fan structure. The blanking mechanism 45 is used to take away the processed product and place the processed product on the blanking assembly - line mechanism 46 for subsequent processing. Thus, the entire operation of scribing the voice - coil and voice - diaphragm combination (adhering the voice - coil lead - out wire of the speaker and the voice diaphragm with glue) is completed. Through the rotation of the turntable 48, the multi - functional fixture rotates to each station in turn to perform corresponding processing on the product to be processed.

[0097] The beneficial effects of the present invention are as follows:

[0098] First, a fully - automatic voice - coil and voice - diaphragm combination scribing machine provided by the present invention can realize the fully - automatic production of adhering the voice - coil lead - out wire of the speaker and the voice diaphragm, reduce labor costs, increase the consistency and stability of the broken - line trajectory in the process of scribing the voice - coil and voice - diaphragm combination, and improve the working efficiency of scribing the voice - coil and voice - diaphragm combination.

[0099] Second, the device for arranging the voice - coil lead - out wire of the speaker solves the problem of fully - automatic positioning of arranging the voice - coil lead - out wire of the speaker during the scribing process of the voice - coil and voice - diaphragm combination, enabling the position of the voice - coil lead - out wire of the speaker to be found during scribing. Among them, the upper - and - lower pressing - cover cylinder mechanism realizes the closing of the voice - coil lead - out wire of the speaker in the up - and - down direction, and the wire - arranging and wire - clamping cylinder mechanism realizes the closing of the voice - coil lead - out wire of the speaker in the horizontal direction, thereby realizing the arrangement of the voice - coil lead - out wire of the speaker. Finally, the fully - automatic positioning of arranging the voice - coil lead - out wire of the speaker is realized, reducing labor costs, increasing the stability in the process of scribing the voice - coil and voice - diaphragm combination, improving the working efficiency of scribing the voice - coil and voice - diaphragm combination, and improving the sound quality of the speaker.

[0100] Third, the broken - line device drives the rotation of the voice - diaphragm / voice - coil assembly and the lead - out wire through the rotation of the broken - line stop shaft and the first broken - line pressing head, so that the outer surface of the broken - line stop shaft drives the lead - out wire to bend to obtain the required broken - line trajectory, preparing the broken - line trajectory for scribing glue at the next station. The fully - automatic broken - line trajectory in the process of scribing and gluing the voice - coil and voice - diaphragm combination is realized, reducing labor costs, increasing the stability in the process of scribing the voice - coil and voice - diaphragm combination, and improving the working efficiency of scribing the voice - coil and voice - diaphragm combination.

[0101] Fourth, before fully automatic folding, use the speaker voice coil lead wire positioning and clamping device to position and clamp the free end of the voice coil lead wire. Specifically, place the speaker sound membrane in the jig. After the front workstation has arranged the lead wire, you can first push the wire clamp rubber cap upward by moving the opening mechanism to open the wire clamp rubber cap, and place the lead wire between the wire clamp rubber cap and the wire clamp guide block. After the adsorption mechanism moves upward, it starts to vacuum so that the speaker sound membrane is adsorbed in the jig, and the opening mechanism moves downward. The lead wire is clamped between the wire clamp rubber cap and the wire clamp guide block. At this point, the positioning and clamping action of the lead wire is completed, which effectively solves the positioning of the lead wire during the marking process of the voice coil and sound membrane combination, so that the lead wire can be accurately positioned during marking.

[0102] The present invention can realize the fully automated production of bonding the voice coil lead wire and the sound film of the speaker, reduce labor costs, increase the consistency and stability of the folding line trajectory in the voice coil and sound film combination scribing process, and improve the voice coil and sound film combination scribing work efficiency. The voice coil lead wire can be fully automatically sorted and grabbed during the voice coil and sound film combination scribing process, thereby improving the sound quality of the speaker; it is a fully automated machine that can fully automatically fold the voice coil lead wire.

[0103] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
