Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling for automated production of loudspeakers. Background Technology

[0002] A loudspeaker is a device that uses an electric current to drive a voice coil to move in a magnetic field formed by a coil and a magnet, thereby driving a diaphragm to produce sound. It typically includes a diaphragm, a voice coil connected to the diaphragm, a frame for fixing the diaphragm, a magnetic circuit system inside the frame, and terminals. The production process of a loudspeaker involves magnetizing the magnet, fixing the diaphragm to the frame, applying adhesive to fix the voice coil to the diaphragm, and soldering the voice coil's leads to the terminals, etc. As can be seen, the production of a loudspeaker involves many components and many processes.

[0003] In related technologies, although the above-mentioned processes can be carried out on an assembly line, they are mostly manual processes, such as product positioning, dispensing, spot welding, tinning, cleaning wire ends, magnetization, etc. The above manual operations require high skill levels from employees. However, due to manual operation, the quality of the products is difficult to guarantee, and the labor cost is also high.

[0004] Therefore, how to improve the quality and efficiency of the automated production process of loudspeakers has become an urgent problem to be solved. Utility Model Content

When the first positioning plate and the second positioning plate are in relative contact, the stepped groove and the positioning groove are coaxially arranged. The push rod passes through the through-hole to push the horn out from the stepped groove into the positioning groove.

[0011] Furthermore, the first magnet is a ring magnet, and the inner diameter of the first magnet is larger than the diameter of the ejector hole.

[0012] Furthermore, the first positioning plate is also provided with a clearance groove, which is connected to the step groove and is used for placing the solder pads on the speaker.

[0013] Furthermore, the first positioning plate also has a protruding positioning post, which is located on the surface of the stepped groove on the first positioning plate, and the second positioning plate also has a positioning hole adapted to the positioning post on the surface of the positioning groove.

[0014] Furthermore, the cable management structure includes two positioning pins that are vertically fixed to the second positioning plate. The positioning pins are located around the positioning groove and are symmetrically arranged on both sides of the pad for cable management.

[0015] Furthermore, the second positioning plate has mounting holes for installing the positioning pin, and the positioning pin is detachably installed in the mounting holes.

[0016] Furthermore, the wire management structure also includes a wire clamp, the clamping direction of which is tangent to the side wall of the positioning pin.

[0019] Furthermore, the first positioning plate and the second positioning plate are both fixed with guide sleeves for positioning on the surface opposite to the stepped groove.

[0020] The beneficial effects of this utility model are as follows: By setting the first magnet in the stepped groove of the first positioning plate, the basin frame is placed in the stepped groove for dispensing, magnetizing, and film application. After the film application is completed, the first positioning plate is aligned with the positioning groove of the second positioning plate. The speaker is then inverted into the positioning groove of the second positioning plate by ejecting the workpiece. The soldering, dispensing, and coiling processes are performed with the help of the wire management structure on the second positioning plate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 8 The tooling shown for automated speaker production includes a first positioning plate 1, a second positioning plate 2, and an ejector workpiece 3, as detailed below. Figure 2 and Figure 3 As shown in the embodiment of this utility model, the first positioning plate 1 has a stepped groove 11 adapted to the bottom of the basin frame, and a first magnet 12 for adsorbing the bottom of the basin frame is fixed at the bottom of the stepped groove 11. It should be noted that the stepped groove 11 in this utility model has at least two steps to fix the magnet and the basin frame respectively, and the diameter of the stepped groove 11 is adapted to the outer diameter of the basin frame, so that the alignment accuracy between the diaphragm and the basin frame is improved by limiting the step groove 11 during the installation of the diaphragm. Of course, it should be noted that in specific use, the stepped groove 11 of the first positioning plate 1 is generally set upward, and the adsorption of the first magnet 12 improves the fixing reliability of the basin frame. With the setting of the first positioning plate 1, operations such as punching, gluing, film application, and film pressing can be realized on the basin frame. As for the implementation of gluing, magnetizing, film application, and film pressing processes, existing automated machinery can be used for automatic processing to improve the processing efficiency of the product.

[0035] Please continue to refer to Figure 3In this embodiment of the present invention, the second positioning plate 2 has a positioning groove 21 adapted to the panel of the speaker rack. A second magnet 22 for adsorbing the panel of the speaker rack is fixed at the bottom of the positioning groove 21. The second positioning plate 2 also has a cable management structure 23 disposed on one side of the positioning groove 21. It should be noted that after the processing on the first positioning plate 1 is completed, the speaker is transferred from the first positioning plate 1 to the second positioning plate 2. In order to improve the convenience of the transfer, in this embodiment of the present invention, the positioning groove 21 is set to be adapted to the panel of the speaker. That is, when it is placed, the speaker is placed in the positioning groove 21 in an upside-down form. The second magnet 22 can improve the stability of the speaker placed in the positioning groove 21.

[0036] like Figure 2 and Figure 3 As shown in the embodiment of this utility model, the transfer of the horn from the first positioning plate 1 to the second positioning plate 2 is completed by ejecting the workpiece 3. Specifically, the ejecting workpiece 3 has a push rod 31, the length of which is not less than the thickness of the first positioning plate 1; the stepped groove 11 has a through ejection hole 13. When the first positioning plate 1 and the second positioning plate 2 are relatively close together, the stepped groove 11 and the positioning groove 21 are coaxially arranged. The push rod 31 passes through the ejection hole 13 to eject the horn from the stepped groove 11 into the positioning groove 21.

[0037] By applying a pushing force from the stepped groove 11 through the push rod 31, when the first positioning plate 1 and the second positioning plate 2 are aligned, the push rod 31 of the ejector fixture can press down to separate the horn from the first positioning plate 1. Then, under the attraction of the second magnet 22 on the second positioning plate 2, the horn is fixed in the positioning groove 21 of the second positioning plate 2. At this time, keeping the positioning fixture still, the first positioning plate 1 is lifted away from the second positioning plate 2, thus realizing the transfer of the horn.

[0038] In the above embodiment, by setting the first magnet 12 in the stepped groove 11 on the first positioning plate 1, the basin frame is placed in the stepped groove 11 for dispensing, magnetizing and film application processes. After the film application is completed, the first positioning plate 1 is aligned with the positioning groove 21 of the second positioning plate 2. The speaker is inverted into the positioning groove 21 on the second positioning plate 2 by ejecting the workpiece 3. The tinning, dispensing and coiling processes are performed with the help of the wire management structure 23 on the second positioning plate 2. The above structure reduces the difficulty of operation for employees and improves the positioning accuracy, thereby improving the processing quality of the product.

[0039] Based on the above embodiments, such as Figure 4As shown, the first magnet 12 is a ring magnet, and the inner diameter of the first magnet 12 is larger than the diameter of the ejector hole 13. With this structure, the attraction force of the first magnet 12 can be guaranteed, so that the push rod 31 does not interfere with the first magnet 12 when pushing the horn.

[0040] Please continue to refer to Figure 4 In this embodiment of the invention, a clearance groove 17 is also provided on the first positioning plate 1. The clearance groove 17 is connected to the step groove 11 and is used for placing the solder pads on the speaker. Since the solder pads are located on the outside of the frame, in order to ensure that the speaker can be stably placed in the step groove 11, the clearance groove 17 is provided to allow the bottom surface of the speaker to better fit with the first magnet 12.

[0041] Please refer to Figure 4 and Figure 5 Since the horn is pushed into the positioning groove 21 from the stepped groove 11, in order to improve the positioning accuracy, the first positioning plate 1 also has a protruding positioning post 14. The positioning post 14 is located on the surface of the stepped groove 11 on the first positioning plate 1. The second positioning plate 2 also has a positioning hole 24 adapted to the positioning post 14 on the surface of the positioning groove 21. In the embodiment of this utility model, both the first positioning plate 1 and the second positioning plate 2 are elongated, and multiple stepped grooves 11 and positioning grooves 21 are arranged in a single row at intervals, which can further improve the processing efficiency.

[0042] Please refer to Figure 6 and Figure 7 In this embodiment of the invention, the cable management structure 23 includes two positioning pins 231 vertically fixed on the second positioning plate 2. The positioning pins 231 are located around the positioning groove 21 and symmetrically arranged on both sides of the pads for cable management. The symmetrically arranged positioning pins 231 allow the cables leading from the pads to pass over the tray opening and hug the PCB, then pass over the positioning pins 231 before exiting, thus forming a symmetrical arc-shaped structure and improving cable management consistency. Furthermore, in this embodiment of the invention, the second positioning plate 2 has mounting holes for installing the positioning pins 231, which are detachably installed in the mounting holes. This detachable installation method allows for the replacement of positioning pins 231 with different diameters as needed; of course, the mating parts of the positioning pins 231 and the mounting holes can be of the same size.

[0043] Furthermore, to improve the stability of the lead wire after it passes around the positioning pin 231 and to prevent it from tilting up, please continue to refer to the embodiments of this utility model. Figure 6 and Figure 7The wire management structure 23 also includes a wire clamping member 232, the clamping direction of which is tangential to the side wall of the positioning pin 231. This structural design allows the wire clamping angle to face the outer wall of the positioning pin 231, further ensuring the lead wire is tightly attached to the solder pad, thus providing a better recognition rate for subsequent CCD visual spot welding.

[0044] In some embodiments of this utility model, the specific structure of the wire clamp 232 is as follows: Figure 6 As shown, the wire clamping member 232 includes a fixed shaft 2321 and two O-rings 2322 sleeved on the fixed shaft 2321. The two O-rings 2322 are arranged side by side, forming a wire clamping space between them. The second positioning plate 2 also has first slots 2323 for locking the two ends of the fixed shaft 2321. The wire is fixed by the compression of the two O-rings 2322. In the embodiment of this utility model, the two ends of the fixed shaft 2321 are fixed by the two first slots 2323. This structure is simple and easy to implement.

[0045] In embodiments of this utility model, such as Figure 8 As shown, the first positioning plate 1 and the second positioning plate 2 have the same outer contour, and the first positioning plate 1 also has feeding grooves 15 at both ends. The function of the feeding grooves 15 on the first positioning plate 1 is to facilitate the transfer of the first positioning plate 1 by tooling such as a robotic arm, i.e., automatic feeding operation. To further improve the reliability of positioning after feeding, please continue to refer to... Figure 8 In this embodiment of the invention, guide sleeves 16 for positioning are fixed on the surface of the first positioning plate 1 facing away from the stepped groove 11 and the surface of the second positioning plate 2 facing away from the positioning groove 21. The guide sleeves 16 can be made of 304 stainless steel to improve wear resistance and extend service life. In this embodiment, the guide sleeves 16 are fixed by a tight fit through mounting holes. The guide sleeves 16 facilitate the positioning and fixing of the first positioning plate 1 and the second positioning plate 2, thereby facilitating subsequent automated processing operations.
