Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing equipment technology, and in particular to a positioning device for loudspeaker assembly. Background Technology

[0002] In the loudspeaker manufacturing industry, the positioning accuracy of the washer and frame directly affects the loudspeaker's sound performance and assembly efficiency. In traditional loudspeaker assembly, the positioning of the washer and frame mainly relies on manual operation or simple tooling fixtures, which has several shortcomings: 1. Insufficient positioning accuracy: When manually placing the washer and frame, operational errors can easily cause relative positional shifts, resulting in voice coil installation deviations, magnetic circuit asymmetry, and other problems, thus affecting the loudspeaker's sound quality stability and yield rate; 2. Poor versatility: Traditional tooling fixtures are mostly designed with fixed specifications, making it difficult to adapt to different sizes and models of washer and frame. Changing product models requires frequent adjustments or replacements of fixtures, increasing downtime and production costs; 3. Low level of automation: The lack of a linkage positioning mechanism means that positioning and clamping processes must be completed step-by-step, making the process cumbersome and time-consuming.

Detailed Implementation

[0021] 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.

[0022] Combination Figures 1-5 The positioning device shown for loudspeaker assembly includes a base 1, a clamping component 2 located at the center of the upper surface of the base 1, and positioning components 3 located on both sides of the base 1 at the clamping component 2. The positioning components 3 are driven by a driving component 4. The clamping component 2 and the positioning components 3 cooperate to position the washer 5 and the frame 6. The clamping component 2 and the positioning components 3 are symmetrically distributed to form a double guarantee, preventing the washer 5 and the frame 6 from shifting during the assembly process, ensuring the accurate installation position of the voice coil, and effectively improving the symmetry and sound quality stability of the loudspeaker magnetic circuit system.

[0023] The base 1 has a first groove 101 at both ends, and a guide groove 102 on both sides of the first groove 101 for installing the positioning component 3. A second groove 103 is provided on one side of the first groove 101 below the guide groove 102 for installing the driving component 4. The base 1 has a cover plate 104 at both ends, and a third groove 105 is provided on the upper surface of the base 1 for installing the clamping component 2.

[0024] The clamping assembly 2 includes two sets of opposing first cylinders 201. A moving block 202 is provided at the output end of the first cylinder 201, and a clamping block 203 is inserted into the moving block 202. The clamping block 203 can be replaced according to different specifications and sizes of washers 5. The clamping assembly 2 adopts a dual-cylinder drive structure, and the two sets of first cylinders 201 move synchronously, driving the moving block 202 to move precisely, ensuring uniform and stable clamping force, and avoiding deformation or displacement of washers 5 and basin frame 6 due to uneven clamping. The design of the plug-in clamping block 203 solves the problem of poor universality of traditional tooling fixtures. When assembling washers 5 and basin frame 6 of different specifications, the operator only needs to simply plug and unplug the clamping block 203 to quickly adapt to the new specifications without the need for complex adjustments to the entire fixture, greatly reducing product model switching time, reducing equipment adjustment costs, and enabling the positioning device to flexibly cope with diverse production needs.

[0025] The positioning component 3 includes a second cylinder 301, with a lifting block 302 at the output end of the second cylinder 301. A positioning post 303 is inserted into the lifting block 302, and the positioning post 303 is inserted into the screw holes of the washer 5 and the basin frame 6. The positioning component 3 drives the lifting block 302 through the second cylinder 301 to realize the lifting action of the positioning post 303, forming an orderly cooperation with the clamping component 2. Before assembly, the positioning post 303 rises and accurately inserts into the screw holes of the washer 5 and the basin frame 6 to complete the initial positioning. After the automatic screw locking device installs screws in other screw holes, the positioning post 303 descends to avoid them, exposing the remaining screw holes for further screw installation. This lifting positioning design not only ensures positioning accuracy but also cleverly avoids the screw installation position, avoiding the interference problem between traditional positioning methods and screw installation, ensuring a smooth and efficient assembly process. At the same time, the plug-in positioning post 303 also supports specification replacement, further improving the device's adaptability to different products.

[0026] Drive assembly 4 includes a lead screw 401 rotatably connected between two sets of cover plates 104. The lead screw 401 is a bidirectional lead screw. Concave blocks 402 are connected to both sides of the lead screw 401 via ball nuts. A second cylinder 301 is mounted on the concave blocks 402, which slide in accordance with the guide groove 102. A first gear 403 is located in the middle of the lead screw 401. A motor 404 is mounted on the second groove 103, and a second gear 405 is located at the output end of the motor 404. The first gear 403 and the second gear 405 mesh and transmit power. Drive assembly 4 adopts a "motor-gear-lead screw" transmission structure. The motor 404 transmits power through gear meshing. The combined rotation of the lead screw 401 drives the concave blocks 402 on both sides to move synchronously along the guide groove 102, thereby precisely adjusting the spacing of the positioning components 3. This transmission method not only has the characteristics of high precision and low error, but also provides a stable driving force, ensuring that the positioning components 3 can quickly and accurately reach the target position during the positioning process of products of different specifications. The adaptive sliding design of the guide groove 102 and the concave blocks 402 further enhances the stability of the movement process, effectively avoiding the shaking and offset of the positioning components 3 during movement, realizing flexible and precise positioning of washers 5 and basin frames 6 of different sizes, and significantly improving production efficiency and equipment automation.
