Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, specifically to an automatic soldering device for loudspeaker production lines. Background Technology

[0002] Speaker manufacturing refers to the process of assembling core components such as voice coils, diaphragms, and magnetic circuit systems into electroacoustic conversion devices through precision assembly technology. Its core processes include magnetic circuit assembly, voice coil winding, diaphragm bonding, lead wire welding, and performance testing. The production process strictly controls key indicators such as airtightness, vibration symmetry, and electrical parameter consistency.

[0003] Currently, the soldering process in speaker production still requires a large amount of manual intervention, including manually placing speaker parts, manually positioning solder joints, adjusting soldering parameters based on experience, and manually removing finished products. Existing semi-automatic soldering equipment can only complete partial soldering actions, resulting in mismatched production cycles, low overall efficiency, and the manual intervention is prone to positioning errors or parameter setting errors, making it difficult to achieve continuous unmanned operation. The level of intelligence is insufficient, and it cannot form a closed-loop control with other modules of the production line, which is not conducive to its use.

[0004] Therefore, an automatic soldering device for speaker production lines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic soldering device for a speaker production line, which solves the problems of low automation level of existing soldering devices in speaker production, inability to meet the requirements of continuous unmanned production, and inability to form a closed-loop control with other modules of the production line.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic soldering device for a speaker production line includes a fixed box. A fixed plate is fixedly connected to the right side of the fixed box, and a cylinder is fixedly connected to the top of the fixed plate. The bottom of the output end of the cylinder passes through the fixed plate and is fixedly connected to a soldering head. A multi-angle adjustment mechanism is fixedly connected to the left side of the fixed box, and a connecting frame is fixedly connected to the bottom of the multi-angle adjustment mechanism. A positioning frame is fixedly connected to the right side between the front and rear sides of the inner cavity of the connecting frame. Electric cylinders are fixedly connected to both sides of the positioning frame. The output ends of the two electric cylinders on opposite sides pass through the positioning frame and are fixedly connected to clamping plates. A flue gas purification component is provided in the inner cavity of the fixed box.

[0008] Preferably, the multi-angle adjustment mechanism includes a hydraulic cylinder, the right side of which is fixedly connected to a fixed box, a transverse movement mechanism is fixedly connected to the bottom of the output end of the hydraulic cylinder, an electric actuator is fixedly connected to the bottom of the transverse movement mechanism, and the right side of the output end of the electric actuator is fixedly connected to a connecting frame.

[0009] Preferably, the lateral movement mechanism includes a control box, the top of which is fixedly connected to the output end of the hydraulic cylinder, a motor is fixedly connected to the rear side of the control box, a screw is fixedly connected to the front side of the motor output end through the control box, a threaded sleeve is threadedly connected to the surface of the screw, a mounting bracket is fixedly connected to the bottom of the threaded sleeve, and the bottom of the mounting bracket passes through the control box and is fixedly connected to the electric push rod.

[0010] Preferably, the front and rear sides of the fixed box are fixedly connected to sliding rods, and the surface of the sliding rods is slidably connected to sliding sleeves, with the left side of the sliding sleeves fixedly connected to the control box.

[0011] Preferably, the flue gas purification component includes a filter element, both sides of which are fixedly connected to the inner wall of the fixed box. The right side of the fixed box has an air intake hole, and the top of the left side of the fixed box is connected to an exhaust fan.

[0012] Preferably, the bottom of the fixed box is fixedly connected to a mounting base, and the mounting base has mounting holes on its bottom and right side. The mounting base is L-shaped.

[0014] Preferably, pressure sensors are fixedly connected to both the front and rear sides of the clamping plate near the electric cylinder, and positioning grooves are provided on opposite sides of the two clamping plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model combines the vertical lifting function of the hydraulic cylinder with the horizontal movement capability of the transverse mechanism through a multi-angle adjustment mechanism. With the extension and retraction adjustment of the electric push rod, it achieves precise positioning of the horn workpiece. The output end of the hydraulic cylinder drives the control box to move vertically along the slide rod, so that the positioning frame can adapt to production lines of different heights. The motor inside the transverse mechanism drives the screw to rotate, which drives the threaded sleeve and the mounting bracket to move horizontally along the screw axis, thereby adjusting the front and rear position of the workpiece. The lateral displacement of the output end of the electric push rod further expands the working radius of the clamping plate, so that the horn can be automatically placed in the welding position, improving the overall automation level and meeting the needs of continuous unmanned production lines.

[0017] 2. This utility model uses a flue gas purification component to adsorb metal oxide particles and volatile organic compounds generated during the soldering process using a filter element. The exhaust fan forms a negative pressure airflow field, which allows the welding fumes to be introduced into the fixed box through the suction hole for filtration and purification. This prevents the fumes generated during the soldering process from spreading and polluting the working environment, and at the same time prevents metal oxide particles from falling onto the surface of the speaker and affecting the cleanliness of the product.

[0026] As one embodiment of this utility model, refer to Figure 1 , Figure 2 and Figure 3The multi-angle adjustment mechanism 5 includes a hydraulic cylinder 51.

A screw 523 is fixedly connected to the front side of the output end of the motor 522 through the control box 521. A threaded sleeve 524 is threaded onto the surface of the screw 523. A mounting bracket 525 is fixedly connected to the bottom of the threaded sleeve 524.

A sliding rod is fixedly connected to the control box 521, and a sliding sleeve is slidably connected to the surface of the sliding rod. The left side of the sliding sleeve is fixedly connected to the control box 521. The hydraulic cylinder 51 is used to adjust the height of the control box 521 so that it can control the height of the positioning frame 7. The transverse mechanism 52 is used to move the positioning frame 7 back and forth so that it can accurately fix the horn. The electric push rod 53 is used to control the left and right position adjustment of the positioning frame 7. By adjusting the positioning frame 7 at multiple angles, it can accurately fix the horn and transfer the horn to the welding position.

[0027] As one embodiment of this utility model, refer to Figure 2 , Figure 4 and Figure 5The flue gas purification assembly 10 includes a filter element 101, both sides of which are fixedly connected to the inner wall of the fixed box 1. A suction hole 102 is provided on the right side of the fixed box 1, and an exhaust fan 103 is connected to the top of the left side of the fixed box 1. A mounting base 11 is fixedly connected to the bottom of the fixed box 1. Mounting holes are provided on the bottom and right side of the mounting base 11, which is L-shaped. An industrial vision camera 12 is fixedly connected to the right side of the bottom of the fixing plate 2, and a panoramic camera 13 is fixedly connected to the front side of the fixing plate 2. Pressure sensors are fixedly connected to the front and rear sides of the clamping plate 9 near the electric cylinder 8. Positioning grooves are provided on opposite sides of the two clamping plates 9. The filter element 101 is used to purify the flue gas and prevent it from contaminating the working parts. The environment is optimized by exhaust fan 103 to exhaust air from the inside of fixed box 1, and suction port 102 to draw welding fumes into fixed box 1 for purification and filtration. Mounting base 11 can install and fix fixed box 1, allowing fixed box 1 to be installed on one side of the production line conveyor belt. Mounting holes can increase the stability of mounting base 11. L-shaped mounting base 11 can be installed and fixed to both the ground and the conveyor belt at the same time. Industrial vision camera 12 and panoramic camera 13 can detect the speaker to be welded above the conveyor belt. When the speaker is delivered to the bottom of positioning frame 7, positioning welding operation starts immediately. Pressure sensor facilitates clamping plate 9 to detect whether the speaker is being clamped normally. Positioning groove can improve the stability of clamping and fixing the speaker.

[0028] Working principle: When the production line conveyor belt transports the horn to the work area, the industrial vision camera 12 and the panoramic camera 13 simultaneously detect the workpiece position, triggering the multi-angle adjustment mechanism 5 to start. The hydraulic cylinder 51 drives the control box 521 to move vertically along the slide bar to the predetermined height. The motor 522 in the transverse mechanism 52 drives the screw 523 to rotate, causing the threaded sleeve 524 to control the mounting bracket 525 to translate along the axis of the screw 523 to the target position. The electric push rod 53 then extends to push the connecting frame 6 to move laterally. After the positioning frame 7 reaches directly above the horn, the hydraulic cylinder 51 continues to control the positioning frame 7 to move downward, so that the horn is located in the inner cavity of the positioning frame 7. Subsequently, the two electric cylinders 8 simultaneously push the clamping plate 9. The speaker is clamped and fixed in motion. The pressure sensor monitors the clamping force in real time and feeds it back to the control system to ensure precise clamping. The speaker is then moved to the welding position by the multi-angle adjustment mechanism 5. The cylinder 3 then drives the soldering head 4 to press down to complete the welding, improving the overall automation level and meeting the needs of continuous unmanned production line. The fumes generated during the welding process are drawn into the fixed box 1 through the suction hole 102 under the negative pressure formed by the exhaust fan 103. The fumes are filtered and purified by the filter element 101 to prevent the fumes generated during the welding process from spreading and polluting the working environment. At the same time, it prevents metal oxide particles from falling onto the speaker surface and affecting the cleanliness of the product.
