[0002] In the loudspeaker manufacturing process, applying adhesive to key components such as the voice coil is an extremely important step. However, current traditional adhesive application methods have significant drawbacks.

[0003] During actual adhesive application, the sprayed liquid is prone to splattering everywhere. This not only results in a significant waste of adhesive material, directly increasing production costs, but also causes the scattered adhesive to adhere to various parts of the production equipment, contaminating and corroding the equipment, affecting its normal operation and lifespan. Furthermore, the splattered adhesive makes the working environment dirty and messy, hindering cleanliness and management of the production site, reducing production efficiency, and making it difficult to guarantee the stability of the adhesive application quality, ultimately affecting the overall quality of the speaker. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a glue-applying device for loudspeaker production. The specific technical solution is as follows:

[0005] A glue-applying device for loudspeaker production includes a working cylinder and a liquid spraying assembly. The liquid spraying assembly includes a liquid spraying sleeve and a liquid-passing section for introducing liquid into the spraying sleeve. Multiple nozzles are circumferentially distributed on the inner sidewall of the bottom end of the spraying sleeve. A liquid guide cylinder is connected to the bottom of the spraying sleeve. The bottom end of the liquid guide cylinder extends movably into the interior of the working cylinder. The spraying sleeve can drive the liquid guide cylinder to move axially towards the working cylinder. An annular filter screen is provided at the top of the working cylinder and inside the liquid guide cylinder. A workpiece clamping part is provided inside the annular filter screen.

[0006] As an improvement to the above technical solution, it also includes an installation frame. The working cylinder is mounted on the installation frame by a bracket. The liquid-conducting part includes a first pump body and a liquid storage tank. The liquid storage tank is mounted on the installation frame. The input end of the first pump body is connected to the inside of the liquid storage tank through a pipe. The output end of the first pump body is connected to the spray sleeve through a liquid-conducting hose.

[0007] As an improvement to the above technical solution: a second pump body is installed on the mounting frame, the input end of the second pump body is connected to the inside of the working cylinder through a pipe, and the output end of the second pump body is connected to the inside of the liquid storage tank through a pipe.

[0008] As an improvement to the above technical solution, it also includes a hydraulic cylinder installed on the mounting frame. The output rod of the hydraulic cylinder is connected to the spray sleeve, and the hydraulic cylinder drives the guide tube connected to the spray sleeve to move away from or closer to the working cylinder.

[0009] As an improvement to the above technical solution: a support rod is connected between the center of the top of the inner wall of the working cylinder and the center of the bottom of the inner wall of the working cylinder.

[0010] As an improvement to the above technical solution: the workpiece clamping part includes a vacuum pump and a chuck connected to the center of the top of the working cylinder. The top of the chuck has a slot adapted to the speaker workpiece. The bottom of the slot is connected to a through groove. A suction cup is provided on the top side inside the through groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. In the adhesive application process, the splashed adhesive liquid will flow downwards along the liquid guide tube or workpiece clamping part, and then pass through the annular filter screen plate before entering the interior of the working cylinder. This design fundamentally solves the problem of adhesive liquid splashing everywhere, maintains a clean production environment, reduces the time and labor costs spent on cleaning adhesive liquid, and also avoids the contamination and damage of the equipment by the adhesive liquid.

[0013] 2. This application utilizes multiple circumferentially distributed nozzles to simultaneously apply adhesive to the workpiece, significantly reducing adhesive application time and improving production efficiency. The hydraulic cylinder drives the spray sleeve and guide tube to move flexibly, allowing for precise adjustment of the adhesive application position and angle according to the specific shape of the workpiece and the adhesive application process requirements, ensuring uniform and accurate adhesive application. Furthermore, the stable clamping effect of the workpiece clamping part effectively prevents workpiece shaking during the adhesive application process, further improving adhesive application quality and reducing product defect rates caused by uneven adhesive application.

[0014] 3. This application utilizes a second pump to recycle the adhesive liquid collected inside the working cylinder into a storage tank, achieving the recycling of the adhesive liquid.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example

[0020] Please refer to Figures 1-2 This utility model relates to the field of loudspeaker manufacturing technology, and in particular to a gluing device for performing precise and efficient gluing operations on workpieces during loudspeaker production, which can effectively solve the problem of glue splashing.

[0021] The adhesive coating device for loudspeaker production of this utility model mainly consists of a working cylinder 2 and a spraying assembly. The spraying assembly includes a spraying sleeve 4 and a liquid conveying section responsible for delivering the adhesive liquid into the spraying sleeve 4. Multiple nozzles 41 are evenly distributed circumferentially on the inner sidewall of the bottom end of the spraying sleeve 4, and the design of these nozzles 41 enables all-around adhesive coating of the workpiece. The bottom of the spraying sleeve 4 is connected to a liquid guiding cylinder 5, the bottom end of which movably extends into the interior of the working cylinder 2, and the spraying sleeve 4 has the function of flexibly moving the liquid guiding cylinder 5 along the axial direction of the working cylinder 2. At the top of the working cylinder 2, an annular filter screen 22 is provided inside the liquid guiding cylinder 5, and a workpiece clamping part 3 for fixing the workpiece is installed inside the annular filter screen 22.

[0022] This application also includes an installation frame 1, on which the working cylinder 2 is securely mounted via a specially designed bracket. The bracket is welded or bolted to both the working cylinder 2 and the installation frame 1 to ensure a strong and reliable connection. The liquid-conducting section consists of a first pump body 7 and a liquid storage tank 6. The liquid storage tank 6 is mounted on the installation frame 1, and its position is carefully designed for easy operation and maintenance. The input end of the first pump body 7 is connected to the interior of the liquid storage tank 6 via a chemically corrosion-resistant pipe. This pipe is sealed to prevent leakage of the adhesive. The output end of the first pump body 7 is connected to the spray sleeve 4 via a liquid-conducting hose 71. The liquid-conducting hose 71 is made of a flexible and wear-resistant material to ensure that it will not break or detach during the movement of the spray sleeve 4.

[0023] A second pump body is also installed on the mounting frame 1. The input end of the second pump body is connected to the inside of the working cylinder 2 via a pipe, and the output end is also connected to the inside of the liquid storage tank 6 via a pipe. All pipe connections are sealed to ensure that the adhesive liquid does not leak during circulation. This design enables the recycling of the adhesive liquid, greatly reduces production costs, and conforms to the concepts of environmental protection and resource conservation.

[0024] The hydraulic cylinder 8 mounted on the mounting frame 1 is a key component for adjusting the position of the spraying assembly. The output rod of the hydraulic cylinder 8 is tightly connected to the spraying sleeve 4 via a flange or welding, ensuring that when the hydraulic cylinder 8 is working, it can stably move the spraying sleeve 4 and the connected guide cylinder 5 away from or towards the working cylinder 2. By precisely controlling the extension and retraction of the hydraulic cylinder 8, the positions of the spraying sleeve 4 and the guide cylinder 5 can be flexibly adjusted to meet the coating requirements of workpieces of different shapes and sizes, improving the accuracy and adaptability of coating.

[0025] To enhance the structural strength of the working cylinder 2, a support rod 21 is connected between the center of the top of the inner wall and the center of the bottom of the inner wall of the working cylinder 2. The support rod 21 is connected to the working cylinder 2 by welding or threading, ensuring that the support rod 21 can effectively withstand various stresses on the working cylinder 2 during use, preventing deformation of the working cylinder 2, and ensuring the stable operation of the entire glue coating device.

[0026] The workpiece clamping part 3 consists of a vacuum pump 34 and a clamping sleeve 31 connected to the center of the top of the working cylinder 2. The top of the clamping sleeve 31 has a groove 30 that precisely matches the shape of the speaker workpiece, and the bottom of the groove 30 communicates with a through groove 32. A suction cup 33 is installed on the top side inside the through groove 32, and a limiting ring 37 is provided at the bottom. A spring 36 is installed between the suction cup 33 and the limiting ring 37. The air supply end of the vacuum pump 34 is connected to a ventilation hose 35, which passes through the limiting ring 37 and the spring 36 before connecting to the suction cup 33. The ventilation hose 35 is sealed to the suction cup 33 and the vacuum pump 34 to ensure no air leakage during the evacuation process. When the vacuum pump 34 is started, the suction cup 33 generates suction under negative pressure. Through the elastic buffering of the spring 36, the speaker workpiece is securely clamped, preventing displacement during the adhesive application process and ensuring the quality of the adhesive application.

[0027] When processing the workpiece, first carefully place the speaker workpiece to be coated with adhesive into the slot 30 of the clamping sleeve 31, ensuring that the workpiece fits tightly into the slot 30. Start the vacuum pump 34, and the vacuum pump 34 starts working, drawing air out of the suction cup 33 through the air hose 35, creating negative pressure in the suction cup 33. Under the elastic action of the spring 36, the suction cup 33 firmly adheres to the workpiece, clamping it securely.

[0028] The first pump body 7 is then restarted. It delivers the adhesive liquid from the storage tank 6 to the spray sleeve 4 via the liquid hose 71. The adhesive liquid is then sprayed from the nozzles 41 distributed circumferentially at the bottom of the spray sleeve 4, applying the adhesive to the workpiece. During the adhesive application process, the hydraulic cylinder 8 is activated according to the shape and size of the workpiece and the adhesive application process requirements. By controlling the extension and retraction of the hydraulic cylinder 8, the positions of the spray sleeve 4 and the guide tube 5 are precisely adjusted to maintain a suitable distance and angle between the nozzles 41 and the workpiece, achieving precise adhesive application. During the adhesive application process, the application effect should be closely observed. If uneven application or missed areas are found, the application parameters should be adjusted promptly, or the equipment should be checked for malfunctions.

[0029] During the adhesive application process, the splashed adhesive liquid flows downwards along the guide tube 5 or the workpiece clamping part 3, and after being filtered by the annular filter screen 22, it enters the working cylinder 2. Once a certain amount of adhesive liquid has been collected in the working cylinder 2, the second pump is activated. The second pump then transports the adhesive liquid in the working cylinder 2 back to the storage tank 6 through a pipeline, achieving the recycling of the adhesive liquid. During the recycling process, the quality of the adhesive liquid should be checked regularly. If impurities or deterioration are found in the adhesive liquid, it should be filtered or replaced promptly to ensure stable performance and guarantee the quality of the adhesive application.

[0030] After the adhesive is applied, first turn off the first pump body 7 to stop the supply of adhesive liquid. Then turn off the vacuum pump 34, release the clamping state on the workpiece, and carefully remove the workpiece after adhesive application.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
