Description

Technical Field

[0001] This utility model relates to the field of voice coil processing equipment, and in particular to a fully automatic voice coil scribing machine. Background Technology

[0002] The voice coil is one of the most important components of a loudspeaker; it is essentially the engine of the loudspeaker. The tolerance requirements for the voice coil are very high, including its height, size, flatness, viscosity, etc. Therefore, this also places high demands on the assembly process of the voice coil. Usually, the voice coil and the diaphragm are assembled by manually applying glue and bonding them together. With the continuous development of the economy, the assembly of voice coils and diaphragms is completed using automated assembly equipment. For example, patent ZL2024204065625 discloses a fully automatic speaker marking and assembly machine, which includes a machine base, a copper ring voice coil assembly station arranged sequentially on the machine base, the copper ring voice coil assembly station including a copper ring conveying mechanism, a copper ring feeding mechanism, a copper ring center glue application mechanism, a voice coil wire handling assembly mechanism, and a copper ring voice coil transition robot; a voice coil marking station, the voice coil marking station including a first copper ring voice coil conveying mechanism, a marking mechanism, a glue application mechanism, and a copper ring voice coil assembly transition robot; and a diaphragm assembly station, the diaphragm assembly station including a second copper ring voice coil conveying mechanism, a flexible diaphragm feeding and magnetizing mechanism, a diaphragm glue application mechanism, an assembly robot, and a finished product unloading mechanism; wherein, when the voice coil marking station transfers the copper ring voice coil assembly to the diaphragm assembly station, it has a transfer vision. Testing agencies inspect copper ring voice coil assemblies; for example, patent ZL2023211628786 discloses a fully automatic production equipment for copper ring voice coil assemblies with marking (same applicant), including a cabinet and a PLC control device on the cabinet, a voice coil assembly station and a marking point white oil station; the voice coil assembly station includes a first tooling turntable with several assembly carriers arranged at its edge, and a copper ring upper mechanism, a glue application mechanism, a winding mechanism and a glue fixing mechanism arranged sequentially around the outer periphery of the first tooling turntable's rotation direction; the marking point white oil station includes a second tooling turntable with several marking carriers arranged at its edge, and a fixed glue application mechanism, a lead wire arc mechanism, a white oil marking mechanism according to the lead wire arc, a heating mechanism and a material unloading robot arranged sequentially along the rotation direction of the second tooling turntable; wherein, a transfer robot is provided between the first tooling turntable and the second tooling turntable.

[0003] However, after the aforementioned equipment assembles the voice coil and diaphragm and fixes them with glue, it is directly sent out of the assembly equipment. After being sent to the equipment, the voice coil assembly needs to be placed in a tray. Since the glue has not yet solidified, the voice coil and diaphragm may become misaligned when handled, resulting in a large number of defective products, which in turn affects production quality and efficiency.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 , Figure 2 and Figure 6 This embodiment provides a fully automatic diaphragm marking machine, including a housing 10 and a control device 20. The housing 10 is provided with a voice coil winding and diaphragm assembly station 30, a voice coil marking and positioning station 40, and an adhesive drying station 50, which are controlled and operated by the control device 20.

[0033] Specifically, the voice coil winding and diaphragm assembly station 30 is used to wind the voice coil and assemble the voice coil and diaphragm to form a diaphragm assembly. The voice coil winding and diaphragm assembly station 30 includes a first intermittent conveying mechanism 31 and a voice coil winding mechanism 32 arranged sequentially along the rotation direction of the first intermittent conveying mechanism 31, a diaphragm feeding mechanism 33 that conveys the diaphragm to the fixture of the first intermittent conveying mechanism 31, a diaphragm gluing mechanism 34 that applies glue to the diaphragm inside the fixture, a voice coil transfer mechanism 35 that transfers the wound voice coil to the fixture and attaches it to the diaphragm and straightens the lead wire, a thermosetting mechanism 36 that dehydrates and cures the glue, and a transfer robot 37.

[0034] The voice coil marking and positioning station 40 is used to mark and position the voice coil lead wire. The voice coil marking and positioning station 40 includes a second intermittent conveying mechanism 41 and a lead wire fixing mechanism 42 arranged in sequence along the rotation direction of the second intermittent conveying mechanism 41 to fix the lead wire to the diaphragm setting position, a wire clamping and marking mechanism 43 to mark the fixed lead wire with an arc and simultaneously cure the adhesive, a single and double pressing mechanism 44 to press the marked lead wire to the diaphragm setting position, a lead wire adhesive marking mechanism 45 to apply adhesive along the lead wire arc, a center adhesive filling mechanism 46 to apply adhesive along the outer periphery of the voice coil, and a visual inspection mechanism 47 to detect whether adhesive has been applied.

[0035] The glue drying station 50 is used to dry the glue moisture on the diaphragm assembly to achieve curing. It includes a conveyor line 51, a feeding robot 52 for conveying the diaphragm assembly on the fixture of the second intermittent conveying mechanism 41 to the conveyor line 51, and a curing oven 53 provided on the conveyor line 51.

[0036] In summary, the working principle of the fully automatic diaphragm marking machine of this application is as follows: the diaphragm is conveyed to the fixture of the first intermittent conveying mechanism 31 by the diaphragm feeding mechanism 33, and then conveyed to the diaphragm gluing mechanism 34 by the first intermittent conveying mechanism 31. The diaphragm gluing mechanism 34 applies glue to the diaphragm. After the glue application is completed, the first intermittent conveying mechanism 31 conveys the diaphragm to the voice coil winding mechanism 32, which winds the enameled wire into a voice coil. The voice coil winding mechanism 32 then conveys the wound voice coil to the transfer voice coil mechanism 35, which receives the voice coil from the voice coil winding mechanism 32 and transfers it to the voice coil transfer mechanism 35. After the voice coil mechanism 35 straightens the lead wires on the voice coil, it transports the voice coil to the fixture and assembles it with the diaphragm. After the voice coil and diaphragm are assembled, the adhesive is instantly cured by the first UV lamp on the side to prevent the diaphragm from being misaligned. After the voice coil and diaphragm assembly is completed, the first intermittent conveying mechanism 31 transports the diaphragm assembly to the thermosetting mechanism 36, where the thermosetting mechanism 36 cures the adhesive to make the voice coil and diaphragm assembly more stable. After completion, the first intermittent conveying mechanism 31 transports the diaphragm assembly to the transfer robot 37, which then transports the diaphragm assembly from the first intermittent conveying mechanism 31 to the fixture of the second intermittent conveying mechanism 41.

[0037] The second intermittent conveying mechanism 41 conveys the diaphragm assembly to the lead wire gluing and fixing mechanism 42. The lead wire gluing and fixing mechanism 42 applies adhesive to the corresponding positions on the lead wire and diaphragm, fixing the lead wire to the corresponding position on the diaphragm for subsequent marking, preventing the voice coil from being pulled during marking. After the lead wire gluing and fixing is completed, the second intermittent conveying mechanism 41 conveys the diaphragm assembly to the wire clamping and marking mechanism 43. The wire clamping and marking mechanism 43 first solidifies the adhesive and then marks the corresponding arc on the lead wire. After marking is completed, the second intermittent conveying mechanism 41 conveys the diaphragm assembly to the single / double upper pressing mechanism 44. The single / double upper pressing mechanism 44 presses the lead wire to the corresponding position on the diaphragm, so that subsequent application of adhesive along the arc direction of the lead wire can fix the lead wire to the diaphragm assembly. The second intermittent conveying mechanism 41 conveys the diaphragm assembly to the lead wire application and gluing mechanism 45, which applies glue according to the arc shape of the lead wire to fix it. After the lead wire is glued, the second intermittent conveying mechanism 41 conveys the diaphragm assembly to the center glue application mechanism 46, which applies glue to the outside of the voice coil to fix the diaphragm and the diaphragm more effectively. At the same time, in order to meet the aging test of the diaphragm assembly of the speaker, it is necessary to prevent the voice coil and the diaphragm from separating under high temperature environment during the aging test. After the glue application is completed, it is conveyed to the visual inspection mechanism 47, where the CCD camera on the visual inspection mechanism 47 takes a picture of the diaphragm assembly and feeds the information back to the control device 20. The control device 20 determines whether the diaphragm assembly has been coated with glue.

[0038] After the inspection is completed, the second intermittent conveying mechanism 41 will transport the diaphragm assembly to the unloading robot 52. The unloading robot 52 will then transfer the diaphragm assembly to the conveyor line 51. The conveyor line 51 will then transfer the diaphragm assembly to the curing oven 53. The curing oven 53 will dry the diaphragm assembly, allowing the adhesive to cure quickly. This will help prevent misalignment of the voice coil and diaphragm when the diaphragm assembly is placed or moved later. After curing, the diaphragm assembly will be sent out of the curing oven 53 by the conveyor line 51.

[0039] It should be noted that the structures of the aforementioned voice coil winding mechanism 32 and voice coil transfer mechanism 35 are the same as the winding mechanism structure and principle described in the fully automatic production equipment for copper ring diaphragm combination with marking disclosed in patent number ZL2023211628786, and will not be repeated here. Furthermore, the first UV lamp is connected and fixed by multiple universal joints, and one of the universal joints is fixed to the housing 10 by a magnet, thereby allowing adjustment of the position of the first UV lamp and facilitating instant curing of the adhesive.

[0040] In this embodiment, please refer to Figure 3 and Figure 4 The diaphragm feeding mechanism 33 includes a feeding disc 330 and a divider 331 for driving the feeding disc 330 to rotate. Multiple diaphragm cylinders 332 for storing diaphragms are arranged circumferentially on the feeding disc 330. Lifting ports communicating with the diaphragm cylinders 332 are opened at corresponding positions on the feeding disc 330 and diaphragm cylinders 332. Each diaphragm cylinder 332 contains a lifting block for gradually lifting the diaphragm. The diaphragm feeding mechanism 33 also includes a lifting rod component for driving the lifting blocks to rise and fall, and a diaphragm feeding robot 333 for picking up diaphragms from the diaphragm cylinders 332 and transferring them to the fixture of the first intermittent conveying mechanism 31. The lifting rod component is located inside the housing 10 and includes a support base 334. A vertical support is mounted on the support base 334. A guide rail is provided, on which a lifting block 335 slides. The lifting block 335 has a vertical push rod 336. A fourth drive unit 337, which drives the lifting block 335 to move up and down along the guide rail, is located on the support base 334. During operation, the feed disc 330 is rotated by the divider 331 at a set angle, causing one of the film cylinders 332 filled with films to rotate below the film feeding robot 333, with the vertical push rod 336 facing the lifting opening. The fourth drive unit 337 drives the lifting block 335 to raise the vertical push rod 336, allowing it to pass through the lifting opening and lift the top block inside the film cylinder 332. This, in turn, causes the films inside the film cylinder 332 to rise, facilitating the film feeding robot 333 to pick up the films. In this embodiment, the fourth drive unit 337 is driven by a motor and a lead screw.

[0041] In order to ensure that the leads of the diaphragm assembly assembled at the voice coil winding and diaphragm assembly station 30 are aligned in the same direction, and to facilitate the application of adhesive by the lead bonding mechanism 42 to the corresponding positions, in this embodiment, please refer to... Figure 5 The output end of the transfer robot 37 is equipped with a rotary drive unit 370, and the output end of the rotary drive unit 370 is equipped with a flexible suction head. A gripper 371 is also provided at the output end of the transfer robot 37, located to the side of the rotary drive unit 370. After the transfer robot 37 drives the flexible suction head to pick up the diaphragm assembly from the first intermittent conveying mechanism 31, the gripper 371 clamps the lead wire, and then the rotary drive unit 370 rotates by a set angle to ensure the lead wire faces a uniform direction. The transfer robot 37 then transports the diaphragm assembly to the fixture of the second intermittent conveying mechanism 41. It should be noted that in this embodiment, the rotary drive unit 370 is a motor. Furthermore, the output end structure of the unloading robot 52 is the same as that of the output end of the transfer robot 37, ensuring that the lead wires of the diaphragm assembly face a uniform direction after unloading, facilitating subsequent mechanized tray placement.

[0042] The straightened lead wire, transferred by the voice coil mechanism 35, is better secured to the diaphragm assembly to prevent misalignment during transport and subsequent pulling of the voice coil during scribing. Therefore, a lead wire adhesive fixing mechanism 42 is provided. This mechanism uses adhesive to fix the lead wire near the voice coil end to the diaphragm assembly, preventing the voice coil from being pulled. Please refer to [link to relevant documentation]. Figure 7 In this embodiment, the main structure of the lead wire dispensing and fixing mechanism 42 includes an adhesive application component and a fixture rotation component.

The unit is equipped with a rotary motor 428. The output shaft of the rotary motor 428 passes through a lifting plate 427 via a linear bearing. The end of the output shaft is fitted with a plug 429 that is lifted by the lifting plate 427 and inserted into the fixture of the second intermittent conveying mechanism 41. The plug 429 is equipped with a rubber suction cup for clamping the fixture. During operation, the second lifting cylinder 426 drives the plug 429 to engage with the fixture on the second intermittent conveying mechanism 41. The first XY axis moving platform 420 drives the first dispensing nozzle to approach the fixture, and the first lifting cylinder 422 drives the first dispensing nozzle to approach the voice coil assembly on the fixture. After the rotary motor 428 drives the fixture to rotate at a set angle, the first dispensing nozzle applies glue to the corresponding positions of the voice coil assembly and the lead wire.

The wire clamping and marking mechanism 43 also includes a second UV lamp 434 for curing the adhesive at the dispensing point. A second intermittent conveying mechanism 41 conveys the voice coil assembly to the second UV lamp 434, where the second UV lamp 434 cures the adhesive at the lead wire dispensing point, preventing the voice coil and diaphragm from shifting during marking. The first mating power component 431 is then activated and engages with the fixture. The second XY-axis moving platform 433 drives the wire clamping component 430 to approach the lead wire, and the wire clamping component 430 clamps the lead wire. The stop pin on the lead wire blocking component 432 blocks the lead wire. The first pair insertion power component 431 drives the fixture to rotate, so that the fixture drives the diaphragm assembly to rotate by a set angle. Due to the stop pin blocking, the lead wire is marked during rotation, so that the lead wire forms an arc along the set path. In this embodiment, the first pair insertion power component has a lifting component, a plug-in, and a motor and belt assembly. The motor and belt assembly is located on the lifting component, and the plug-in is located on the motor and belt assembly. The lifting component drives the motor and belt assembly to rise, so that the plug-in is inserted into the bottom of the fixture. The motor and belt assembly drives the plug-in to drive the fixture to rotate. The wire clamping component 430 includes a lifting component and a pneumatic gripper 371 located on the lifting component. The second XY-axis moving platform 433 drives the lifting component to move the pneumatic gripper 371 to approach the lead wire, and the lifting component drives the pneumatic gripper 371 to move down, so that the pneumatic gripper 371 clamps the lead wire.

The moving drive assembly 461 includes a bracket 4610, a connecting plate 4611 at the upper end of the bracket 4610, a guide rail along the length of the connecting plate 4611, a slide block 4612 sliding on the guide rail, and a [missing information - likely a design feature] at one end of the connecting plate 4611. A first push cylinder 4613 is provided to drive the slide block 4612 to reciprocate along the guide rail; the slide block 4612 is provided with a vertical slide rail, and a slide plate 4614 is slidably mounted on the vertical slide rail. The third glue nozzle 460 is located on the slide plate 4614, and the slide block 4612 is provided with a second push cylinder 4615 to drive the slide plate 4614 to slide up and down along the vertical slide rail; during operation, after the second insertion power component 462 is inserted into the fixture, the first push cylinder 4613 drives the slide block 4612 to move the third glue nozzle 460 above the fixture, and then the second push cylinder 4615 drives the slide plate 4614 to move down, so that the third glue nozzle 460 is close to the outside of the voice coil. At this time, the second insertion power component 462 drives the fixture to rotate, so that the third glue nozzle 460 applies glue along the circumference of the voice coil.

[0047] To prevent the adhesive from solidifying on the nozzle of the third dispensing nozzle 460, and to prevent the adhesive outside the exposed nozzle from lingering and attracting dust for an extended period, a cleaning component 463 is provided. Please refer to [link / reference needed]. Figure 12The cleaning assembly 463 includes a support plate 4630 fixed on a bracket 4610. The support plate 4630 is provided with a rotating arm 4631. One end of the rotating arm 4631 is provided with a tensioning shaft. The rotating arm 4631 is provided with a cleaning cup 4632. The other end of the rotating arm 4631 is provided with a movable groove. The support plate 4630 is also provided with a third push cylinder 4633. The output end of the third push cylinder 4633 is provided with a connecting block 4634. The connecting block 4634 is provided with a rotating shaft connected to the movable groove. The bottom of the cleaning cup 4632 is provided with a drain port, and the tensioning shaft is provided with a pipe connection port communicating with the drain port. During cleaning, the first push cylinder 4613 drives the slide block 4612 to move the third adhesive nozzle 460 above the cleaning cup 4632. Then, the second push cylinder 4615 drives the slide plate 4614 to move down, causing the third adhesive nozzle 460 to fall into the cleaning cup 4632. Simultaneously, the first push cylinder 4613 and the third push cylinder 4633 work together, so that while the third adhesive nozzle 460 is reciprocated by the first push cylinder 4613, the cleaning cup 4632 is rotated by the third push cylinder 4633, causing the cleaning fluid in the cleaning cup 4632 to clean the third adhesive nozzle 460. It should be noted that in this embodiment, the structure of the diaphragm feeding mechanism 33 is the same as the structure of the center adhesive filling mechanism 46.

[0048] In summary, this utility model achieves a fully automated production process for the diaphragm assembly, from winding, assembly, marking to adhesive curing, through the setting of a voice coil winding and diaphragm assembly station 30, a voice coil marking and positioning station 40, and an adhesive drying station 50. Specifically, the voice coil winding and diaphragm assembly station 30 automatically completes the winding of the voice coil and the assembly of the voice coil and diaphragm, greatly improving production efficiency. The voice coil marking and positioning station 40 accurately marks and positions the voice coil leads, ensuring a high product yield. The adhesive drying station 50 cures the adhesive by drying its moisture, effectively avoiding misalignment of the voice coil and diaphragm due to incomplete adhesive curing.
