Description

Technical Field

[0001] This utility model relates to the field of processing equipment, and in particular to a loudspeaker processing equipment. Background Technology

[0002] As the core acoustic output component of various electronic devices, the loudspeaker's manufacturing process is characterized by multiple steps and high precision. It requires the sequential completion of key processes such as diaphragm molding, voice coil winding, magnetic circuit assembly, and adhesive curing. The processing precision of each step directly affects the loudspeaker's final acoustic performance, such as frequency response, sensitivity, and distortion.

[0003] In existing speaker manufacturing equipment, raw materials such as diaphragm substrates, voice coil frames, and magnets are first placed in batches on the equipment's material rack. After the equipment is started, the conveying mechanism delivers the diaphragm substrates to the forming station to complete the diaphragm surface processing. Then, it is transferred to the voice coil assembly station. After being positioned by a fixture, the winding module winds the enameled wire onto the frame and fixes it. Subsequently, the workpiece is transferred to the magnetic circuit assembly station, where the glue dispensing module applies glue to the joint between the magnet and the magnetic guide plate. The pressing assembly completes the bonding. Finally, after being processed at the curing station, the testing module performs preliminary testing on the speaker's acoustic parameters. Qualified workpieces are collected by the unloading mechanism.

[0004] Existing speaker processing equipment has significant shortcomings in the glue-dispensing process. Firstly, most glue-dispensing components are integrated units. When malfunctions such as clogged dispensing valves or leaking glue supply lines occur, the entire glue-dispensing structure must be disassembled for repair. This not only involves cumbersome disassembly but also prolongs equipment downtime, impacting production efficiency. Furthermore, after long-term operation, glue residue and dust easily accumulate at the glue-dispensing station, yet there is a general lack of targeted dust cleaning mechanisms. Dust mixed into the glue material affects dispensing accuracy. Secondly, the curing structure after glue dispensing typically uses heat curing. If the temperature is not uniformly controlled during heating, it can lead to inconsistent glue shrinkage, causing deformation of components such as the speaker diaphragm and magnetic circuit, resulting in product defects. It can also damage the original properties of the glue material, reducing the overall lifespan of the speaker. Therefore, a speaker processing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a speaker processing device, which aims to improve the problems of inconvenient maintenance of components such as glue injection, lack of dust removal structure, and easy product defects caused by heat curing in the existing speaker processing device.

[0036] Reference Figure 1 , Figure 5 The top outer wall of the mounting base plate 1 is equipped with a dust removal structure to remove dust from the workpiece surface and prevent contamination of the adhesive. This structure includes a mounting frame 2, which provides support for the dust removal structure. A guide rod 22 is fixedly connected to the outer wall of the mounting frame 2, guiding the movement of the sliding sleeve 21. The sliding sleeve 21 is slidably connected to the outer wall of the guide rod 22, allowing the mounting plate 20 to move along the guide rod 22. The mounting plate 20 is fixedly connected to the outer wall of the sliding sleeve 21, and is used to mount the tubular electrostatic precipitator 19. The outer wall of the mounting plate 20 is equipped with a tubular... The tubular electrostatic precipitator 19 establishes a high-voltage electrostatic field between the internal cathode wire and the anode tube, causing the gas in the electric field to ionize and generate electrons. The electrons attach to the surface of the dust particles, making them negatively charged. The negatively charged dust particles are adsorbed onto the inner wall of the anode tube under the action of the electric field force, thus achieving the separation of dust from air and producing the effect of electrostatic adsorption of dust.

[0039] Reference Figures 3-4 , Figure 8 A stepper motor 13 is fixedly connected to the top outer wall of the mounting base plate 1. The stepper motor 13 can drive the robotic arm 14 to rotate precisely. The output end of the stepper motor 13 is fixedly connected to the robotic arm 14. The robotic arm 14 is right-angled and can achieve efficient operation of gripping and lowering the placement tray 6 at the same time. It can also move in multiple directions to adjust the position of the gripper 16. A connecting block 15 is fixedly connected to the bottom outer wall of the robotic arm 14. The connecting block 15 is used to connect the robotic arm 14 and the gripper 16. It relies on air pressure to drive the internal piston to drive the gripper 16 to complete the gripping action. The inner wall of the connecting block 15 is provided with the gripper 16. The gripper 16 is used to grip the placement tray 6. The outer wall of the gripper 16 is provided with a slot 17. The outer wall of the buckle 7 is adapted to the inner wall of the slot 17. Through the engagement of the slot 17 and the buckle 7, it is ensured that the gripper 16 is stable and does not fall off when gripping the placement tray 6.

[0040] Reference Figures 1-3 A rotating motor 3 is fixedly connected to the top outer wall of the mounting base plate 1. The rotating motor 3 can drive the turntable 4 to rotate, realizing the switching of the workpiece between different processing stations. The output end of the rotating motor 3 is fixedly connected to the turntable 4, which is used to support the placement tray 6. The top outer wall of the turntable 4 is provided with a positioning hole 5. The inner wall of the positioning hole 5 is adapted to the fixing block provided on the bottom outer wall of the placement tray 6. Through the cooperation between the fixing block and the positioning hole 5, the placement tray 6 is accurately positioned on the turntable 4. The top of the mounting base plate 1 is fixedly connected to the mounting bracket 2. The mounting bracket 2 is also used to install the infrared detector 23. The outer wall of the mounting bracket 2 is fixedly connected to the infrared detector 23. The infrared detector 23 can accurately detect the position of the workpiece and provide positioning basis for glue injection and gripping.

[0041] Working principle: When this speaker processing device is working, the speaker workpiece to be processed is first placed into the placement tray 6. After the device is started, the motor 9 of the conveyor structure drives the transmission wheel 8 to rotate. The transmission wheel 8 drives the transmission belt 12 to move, transporting the placement tray 6 carrying the workpiece to the designated position. Subsequently, the stepper motor 13 drives the right-angle robotic arm 14 to move. The connecting block 15 at the bottom of the robotic arm 14 uses air pressure to drive the internal piston, causing the gripper 16 to open. The gripper 16 engages with the buckle 7 on the outer wall of the placement tray 6 through the slot 17, realizing the gripping of the placement tray 6. At the same time, the robotic arm... The robotic arm 14 can simultaneously grip the workpiece placement tray 6 from the conveyor belt 12 and lower the finished workpiece placement tray 6, achieving efficient transfer. The robotic arm 14 places the workpiece placement tray 6 into the positioning hole 5 of the turntable 4, achieving precise positioning through the cooperation of the bottom fixing block of the placement tray 6 with the positioning hole 5. The rotating motor 3 drives the turntable 4 to rotate, sequentially transferring the workpieces to each processing station. When the workpiece reaches the dust removal station, the electric push rod 18 of the dust removal structure pushes the mounting plate 20 downwards along the guide rod 22, bringing the tubular electrostatic precipitator 19 closer to the workpiece. The electrostatic precipitator 19 establishes a high-voltage electrostatic field through its internal cathode wire and anode tube, ionizing the gas to generate electrons. These electrons adhere to the surface of dust particles, making them negatively charged. Under the influence of the electric field, the negatively charged dust particles are adsorbed onto the inner wall of the anode tube, thus completing the removal of dust from the workpiece surface. After dust removal, the turntable 4 transfers the workpiece to the glue injection station. The electric push rod 18 of the glue injection structure pushes the mounting plate 20 to adjust the position of the glue injection nozzle 25. The infrared detector 23 on the mounting frame 2 accurately detects the workpiece position, providing a positioning basis for the glue injection nozzle 25, which then injects the glue into the designated position on the workpiece. The adhesive is dispensed, and at the same time, the ultrasonic transmitter 24 at the nozzle generates high-frequency vibration, causing air bubbles in the adhesive to gather and float to the surface, ensuring the quality of dispensing. After the dispensing is completed, the turntable 4 transfers the workpiece to the curing station. The electric push rod 18 of the curing structure pushes the fixing frame 26 down, bringing the UV curing lamp 27 closer to the adhesive layer. The UV curing lamp 27 emits ultraviolet light, which causes the UV adhesive to cure quickly. After all processing steps are completed, the robotic arm 14 grabs the placement tray 6 containing the finished product and places it onto the transmission belt 12, which then transports it to the unloading area, completing the entire speaker processing flow.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
