Technical Field

[0001] This utility model relates to the field of notebook computer diaphragm technology, specifically a diaphragm handling and rotating molding device. Background Technology

[0002] Diaphragms (such as loudspeaker diaphragms and receiver diaphragms) are the core vibrating components in electroacoustic transducers. Their production and assembly precision directly determines the frequency response, distortion, and reliability of acoustic devices. In the automated assembly line of electroacoustic components, especially miniature, high-precision loudspeakers and receivers, the picking, handling, and posture adjustment of diaphragms, as well as their precise alignment and molding with components such as voice coils and magnetic circuit systems, is a crucial process. In the manufacturing process of laptop speakers, the precise molding of the diaphragm and the frame is one of the key processes. Its quality directly affects the acoustic performance, reliability and final listening experience of the speaker unit. However, the mainstream production methods in the current technology still rely on a large amount of manual operation and semi-automated equipment. However, due to the thinness and easy deformation of the diaphragm material, it is difficult to maintain its shape stability during manual handling and transportation. It is very easy to cause creases, dents or dust accumulation due to uneven force or electrostatic adsorption, resulting in a decrease in product qualification rate. Therefore, we need to propose a diaphragm handling and rotation molding device. Utility Model Content

The diaphragm is clamped and transferred by the diaphragm tooling handling module, and then placed on the diaphragm tooling flipping module to achieve preliminary mold-closing of the diaphragm and the frame. Compared with traditional manual mold-closing, it has higher mold-closing accuracy and improves mold-closing efficiency. It can avoid damage caused by instability during manual handling, thereby improving the mold-closing quality and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a diaphragm transporting and rotating mold-closing device, comprising: The transport module and the mold closing module disposed below the transport module are provided. The transport module is used to grab the tooling loaded with the sound diaphragm to the mold closing module. The mold closing module flips the tooling loaded with the sound diaphragm and presses it onto the frame magazine for mold closing. The material transfer module streamline and the blocking and positioning module located directly below the material transfer module streamline support and position the frame clip and the sound diaphragm tooling when they are molded together.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 This utility model provides a technical solution: a diaphragm transport and rotation mold closing device, including a transport module 3, a mold closing module 4 disposed below the transport module 3, a material transfer module streamline 5, and a blocking and positioning module 6 disposed directly below the material transfer module streamline 5; The conveying module 3 is used to grab the tooling loaded with the sound diaphragm to the mold closing module 4. The mold closing module 4 flips the tooling loaded with the sound diaphragm and presses it onto the frame magazine for mold closing. The blocking and positioning module 6 supports and positions the frame magazine and the sound diaphragm tooling during mold closing.

[0016] In this embodiment, the mold closing module 4 includes a lifting platform 42. A rotary motor 44 is installed on the upper surface of the lifting platform 42. The output end of the rotary motor 44 is connected to a flip plate 45. A second pneumatic gripper 46 for limiting the position of the diaphragm fixture is installed on one end of the upper surface of the flip plate 45. The mold closing module 4 drives the flip plate 45 to flip through the rotary motor 44. The second pneumatic gripper 46 limits and fixes the diaphragm fixture, ensuring that the posture of the diaphragm fixture is stable during the flipping process, avoiding displacement or detachment of the diaphragm, realizing smooth mold closing of the diaphragm and the frame, and improving the accuracy of the mold closing action.

[0017] Secondly, a second bracket 41 is provided below the lifting platform 42 to guide the lifting of the lifting platform 42. A lifting cylinder 43 is installed on the second bracket 41 to drive the lifting of the lifting platform 42. The second bracket 41 provides a stable lifting guide for the lifting platform 42. The lifting cylinder 43 drives the lifting platform 42 to accurately adjust its height, which can be adapted to different specifications of frame clips and diaphragm tooling, improve the versatility of the device, and at the same time ensure smooth pressure transmission during mold closing, avoiding poor mold closing due to height deviation.

[0018] In a further preferred embodiment, the transport module 3 includes a first support 31, a horizontal linear module 32 is mounted on the top of the first support 31, a vertical linear module 33 is mounted on the movable end of the horizontal linear module 32, and a first pneumatic gripper 34 for clamping the diaphragm tooling is mounted on the movable end of the vertical linear module 33. The transport module 3 adopts a combination structure of the horizontal linear module 32 and the vertical linear module 33 to achieve precise displacement of the diaphragm tooling in the horizontal and vertical directions. The first pneumatic gripper 34 clamps reliably and is evenly stressed, effectively protecting the diaphragm from damage and improving the stability and positioning accuracy of the transport process.

[0019] The basic structure (such as guide rails, ball screws, drive motors, sliders, etc.), working principle (the motor drives the screw to rotate, causing the slider to make linear displacement along the guide rail) and selection criteria (selecting the appropriate specifications according to the requirements of load, stroke, positioning accuracy, etc.) of the horizontal linear module 32 and the vertical linear module 33 are well known to those skilled in the art. Their core function is to realize the precise linear movement of the load in the horizontal and vertical directions. The relevant technologies have been fully disclosed and are mature and commercially available.

[0020] Specifically, this device also includes a base plate 1, and the conveying module 3, the mold closing module 4, and the blocking and positioning module 6 are all installed on the upper surface of the base plate 1. The upper surface of the base plate 1 is equipped with a conveying module flow line 2 for conveying the sound diaphragm tooling to the conveying module 3. By integrating the conveying module 3, the mold closing module 4, the blocking and positioning module 6, and the conveying module flow line 2 through the base plate 1, the device has a compact structure and reasonable layout, which facilitates installation, debugging, and maintenance. The conveying module flow line 2 realizes the automated conveying of the sound diaphragm tooling, reduces manual transfer links, improves production continuity, and thus improves overall operation efficiency.

[0021] It is worth noting that the blocking and positioning module 6 includes a lifting and positioning mechanism 61 and two sets of blocking mechanisms 62. The lifting and positioning mechanism 61 and the flip plate 45 are set on the same plane, and the positioning mechanism is set between the two sets of blocking mechanisms 62. The two sets of blocking mechanisms 62 of the blocking and positioning module 6 can accurately intercept the frame cartridge. The lifting and positioning mechanism 61 and the flip plate 45 are set on the same plane, which can stably support and position the mold closing part, prevent the frame cartridge or diaphragm tooling from shifting during mold closing, ensure the mold closing alignment accuracy, and reduce the defect rate.

[0022] In addition, this device also includes a repressing module 7 installed on the upper surface of the base plate 1. The repressing module 7 includes a third bracket 71 installed on the upper surface of the base plate 1. A booster cylinder 72 is provided on the third bracket 71, and a pressure plate 73 that slides along the third bracket 71 is fixedly connected to the piston end of the booster cylinder 72. The repressing module 7 drives the pressure plate 73 to slide along the third bracket 71 through the booster cylinder 72 to apply secondary pressure to the molded product, strengthen the fit between the diaphragm and the frame, avoid problems such as poor fit and gaps, further improve the mold quality and product structural stability, and thus ensure the final performance of the acoustic device.

[0023] It is worth noting that this device is suitable for molding the diaphragm and frame of laptop speakers / micro speakers / receivers. Suitable diaphragm materials include thin diaphragms such as PEEK, polyimide, and paper, and frame materials include ABS, aluminum alloy, and stainless steel. The rotary motor 44 is a servo motor. Both the lifting cylinder 43 and the booster cylinder 72 are equipped with magnetic ring sensors to provide positioning feedback. The grippers of the first pneumatic gripper 34 and the second pneumatic gripper 46 are made of polyurethane to avoid scratching the diaphragm tooling. Pressure sensors are also provided to prevent over-gripping and damage to the tooling. The specific operating principles and wiring connections are existing technologies and will not be described in detail.

[0024] This device uses a PLC controller and a touch screen to set and monitor parameters. It also uses an I / O module to interact with signals. When changing to different specifications of diaphragm and frame, only the corresponding diaphragm tooling and frame clip need to be replaced, and the PLC parameters can be modified through the touch screen. The specific parameter settings are set according to the production process and will not be described in detail here.

[0025] In use, the conveyor module 2 transports the tooling loaded with the diaphragm to the working range of the transport module 3. The horizontal linear module 32 and the vertical linear module 33 of the transport module 3 work together to drive the first pneumatic gripper 34 to accurately grab the diaphragm tooling and transfer it to the flip plate 45 of the mold closing module 4. The second pneumatic gripper 46 completes the limiting and fixing. At the same time, the material transfer module 5 transports the frame clip to the mold closing station. The blocking mechanism 62 of the blocking positioning module 6 intercepts the frame clip, and the lifting positioning mechanism 61 rises to achieve accurate positioning. Subsequently, the lifting cylinder 43 of the mold closing module 4 drives the lifting platform 42 to adjust to a suitable height. The rotary motor 44 drives the flip plate 45 to rotate 180°, so that the diaphragm tooling is accurately aligned with the frame clip below after positioning and the initial mold closing is completed. After the mold is closed, the product is transferred to the underside of the repressing module 7 and further positioned by the blocking positioning module. The pressure plate 73 is driven downward by the booster cylinder 72 to apply secondary pressure, ensuring a firm fit.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
