Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing, specifically to a loudspeaker manufacturing fixing and correction device. Background Technology

[0002] A loudspeaker is a commonly used electroacoustic transducer that converts electrical signals into sound signals. Loudspeakers are divided into built-in loudspeakers and external loudspeakers.

[0003] According to publicly available patent CN222424017U, a loudspeaker processing and fixing correction device, relating to the field of loudspeaker production equipment, includes a base plate. A mounting bracket is fixedly connected to the top center of the base plate. A slot is formed on the top of the mounting bracket. A flexible cylinder is positioned above the mounting bracket. Connecting rings are fixedly connected to both the upper and lower ends of the flexible cylinder. Four ear plates are fixedly connected to the outer sides of each of the two connecting rings. Guide posts are slidably connected inside each of the four ear plates. Two sleeves are fixedly connected to the middle of the flexible cylinder, with the openings of the two sleeves facing opposite directions. Thin ropes are installed inside the sleeves. This invention... During the process, the inventors discovered that the existing technology has at least the following unresolved problems: By holding two thin ropes and pulling them outwards, the middle of the flexible cylinder contracts, the diaphragm lies flat inside the flexible cylinder, and the flexible cylinder descends. Just before the flexible cylinder contacts the speaker, it is straightened, and the diaphragm descends along the flexible cylinder and attaches to the speaker, facilitating its fixation and correction, effectively achieving rapid positioning and improving work efficiency. However, in practice, the traditional diaphragm attachment operation is cumbersome and cannot be continuously attached to the speaker, thus affecting the efficiency of diaphragm attachment. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a speaker processing, fixing and correcting device to solve the technical problem that the current diaphragm attaching operation is relatively time-consuming and cannot continuously attach the diaphragm to the speaker, thus affecting the efficiency of diaphragm attaching.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A loudspeaker processing, fixing, and correction device is designed, comprising:

[0006] A fixing mechanism, the fixing mechanism including a drive disk disposed on the surface of the processing table, the surface of the drive disk having four fixing grooves;

[0007] A film-applying mechanism includes a support plate fixedly connected to one side of the processing table surface. A first drive motor is provided at one end of the support plate near the drive disk. A connecting shaft is fixedly connected to the drive end of the first drive motor. A drive roller is fixedly connected to the outside of the connecting shaft. Four film-applying tubes are fixedly connected to the outside of the drive roller. A lifting mechanism is provided between the first drive motor and the support plate.

[0008] The transmission mechanism includes a transmission rod fixedly connected to the middle of the surface of the drive disk, a first bevel gear fixedly connected to the top of the transmission rod, and a second bevel gear fixedly connected to the end of the connecting shaft away from the first drive motor, the second bevel gear meshing with the first bevel gear.

[0009] Preferably, the lifting mechanism includes an adjustment groove formed on the support plate near the first drive motor. A lead screw is rotatably connected between the upper and lower ends of the inner cavity of the adjustment groove via bearings. An adjustment block is slidably connected in the adjustment groove, and the adjustment block is threaded onto the outside of the lead screw. The first drive motor is fixedly connected to the adjustment block. A second drive motor is fixedly installed on the top of the support plate. The drive end of the second drive motor rotatably passes through the support plate and is connected to the lead screw via a coupling.

[0010] Preferably, a third drive motor is fixedly installed at the bottom of the processing table, and the drive end of the third drive motor rotates through the bottom center of the processing table and the drive disk.

[0011] Preferably, both the drive roller and the film-applying tube are hollow structures, and the inner cavities of the drive roller and the film-applying tube are interconnected. An adsorption hole is provided at the end of the film-applying tube away from the drive roller, and a negative pressure pump is fixedly installed at the end of the drive roller near the first drive motor. An air suction pipe is connected between the air suction end of the negative pressure pump and the drive roller.

[0012] Preferably, the first bevel gear and the second bevel gear have the same specifications.

[0013] Preferably, an electric slip ring is provided on the outer side of the drive end of the first drive motor. The electric slip ring includes a rotor and a stator. The rotor is connected to the drive end of the first drive motor by bolts, and the stator is connected to the housing of the first drive motor by bolts. The rotor is electrically connected to the negative pressure pump by wires, and the stator is connected to an external power source by wires.

[0014] Preferably, the fixing groove has notches on both sides, and the two notches are symmetrically distributed on both sides of the fixing groove.

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

[0016] This invention combines a film-applying tube, a drive disc, a fixing groove, a drive roller, a first drive motor, and a lifting mechanism. After the speaker to which the diaphragm needs to be applied is placed in the fixing groove, the diaphragm is pasted onto the film-applying tube, with the center of the tube aligned with the center of the speaker. Then, the second drive motor is activated, driving the lead screw to rotate. This, in conjunction with an adjusting block, guides the movement within the adjusting groove, thus attaching the diaphragm from the film-applying tube to the speaker. Once the speaker diaphragm is applied, the second drive motor is activated in the reverse direction, causing the drive roller to move upwards and engage with the first bevel gear. When applying the diaphragm to the next speaker, the drive disc is rotated 90°, aligning with the first and second bevel gears (which are of the same specification). This 90° rotation of the drive disc drives the drive roller to rotate 90°, ensuring the center of the next film-applying tube is aligned with the center of the next speaker. This automatic positioning and continuous diaphragm application further improves work efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A loudspeaker processing and fixing correction device, see [link to example]. Figures 1 to 3The system includes: a fixing mechanism, comprising a drive disk 2 disposed on the surface of a processing table 1, the drive disk 2 having four fixing grooves 21 on its surface; and a film-applying mechanism, comprising a support plate 4 fixedly connected to one side of the surface of the processing table 1, a first drive motor 5 disposed at one end of the support plate 4 near the drive disk 2, a connecting shaft 51 fixedly connected to the drive end of the first drive motor 5, a drive roller 52 fixedly connected to the outer side of the connecting shaft 51, four film-applying tubes 53 fixedly connected to the outer side of the drive roller 52, and a lifting mechanism disposed between the first drive motor 5 and the support plate 4, the lifting mechanism including an adjusting groove 41 disposed at one end of the support plate 4 near the first drive motor 5, the upper and lower ends of the inner cavity of the adjusting groove 41 being rotatably connected by bearings. A lead screw 42 is connected to the support plate 4. An adjusting block 44 is slidably connected in the adjusting groove 41, and the adjusting block 44 is threaded onto the outside of the lead screw 42. The first drive motor 5 is fixedly connected to the adjusting block 44. A second drive motor 43 is fixedly installed on the top of the support plate 4. The driving end of the second drive motor 43 rotates through the support plate 4 and is connected to the lead screw 42 through a coupling. The transmission mechanism includes a transmission rod 3 fixedly connected to the middle of the surface of the drive disc 2. A first bevel gear 31 is fixedly connected to the top of the transmission rod 3. A second bevel gear 32 is fixedly connected to the end of the connecting shaft 51 away from the first drive motor 5. The second bevel gear 32 meshes with the first bevel gear 31. The first bevel gear 31 and the second bevel gear 32 have the same specifications.

[0023] During operation, the speaker to which the diaphragm needs to be attached is placed into the fixing groove 21, and the diaphragm is pasted onto the diaphragm tube 53, with the center of the diaphragm tube 53 aligned with the center of the speaker. Then, the second drive motor 43 is started to drive the lead screw 42 to rotate, which, in conjunction with the adjusting block 44, guides the movement within the adjusting groove 41, thereby causing the diaphragm on the diaphragm tube 53 to be attached to the speaker. After the speaker diaphragm is attached, the second drive motor 43 is started to rotate in the reverse direction, thereby driving the drive roller 52 to move upward, and causing the second bevel gear 32 and the first bevel gear to... When the bevel gear 31 meshes, the drive disk 2 rotates 90° to engage with the first bevel gear 31 and the second bevel gear 32. Since the first bevel gear 31 and the second bevel gear 32 are of the same specification, the drive disk 2 rotates 90° and drives the drive roller 52 to rotate 90°. This aligns the center of the next film-applying tube 53 with the center of the next speaker, thereby automatically fixing and correcting its position and enabling continuous film application to the speakers, further improving work efficiency.

[0024] For details, see Figure 1A third drive motor 33 is fixedly installed at the bottom of the processing table 1. The drive end of the third drive motor 33 rotates through the processing table 1 and connects to the bottom center of the drive disk 2. Through the setting of the third drive motor 33, the drive disk 2 can be automatically driven to rotate intermittently by 90° (the intermittent rotation of the drive disk 2 by controlling the number of rotations of the motor is achieved, and the number of rotations of the motor is a known technology, which will not be elaborated here) to attach the diaphragm of the speaker.

[0025] Further, see Figure 1 Both the drive roller 52 and the film-applying tube 53 are hollow structures, and their inner cavities are interconnected. The film-applying tube 53 has an adsorption hole 54 at the end away from the drive roller 52. A negative pressure pump 6 is fixedly installed at the end of the drive roller 52 near the first drive motor 5. An air intake pipe 61 connects the air intake end of the negative pressure pump 6 to the drive roller 52. When the diaphragm is placed on the film-applying tube 53, the negative pressure pump 6 is activated to generate negative pressure at the adsorption hole 54, thereby adsorbing the diaphragm onto the film-applying tube 53. This improves the stability of the diaphragm's adhesion to the film-applying tube 53 and prevents the diaphragm from falling off due to the rotation of the film-applying tube 53, which would affect the adhesion of the speaker's diaphragm.

[0026] It is worth noting that, see Figure 1 An electric slip ring 7 is provided on the outer side of the drive end of the first drive motor 5. The electric slip ring 7 includes a rotor and a stator. The rotor is connected to the drive end of the first drive motor 5 by bolts, and the stator is connected to the housing of the first drive motor 5 by bolts. The rotor is electrically connected to the negative pressure pump 6 by wires, and the stator is connected to an external power source by wires. By setting the electric slip ring 7, the electrical energy of the negative pressure pump 6 can be continuously increased when the first drive motor 5 rotates, so that when the drive roller 52 rotates, the adsorption hole 54 is in a negative pressure state, ensuring that the film-adhesive tube 53 can adsorb the sound membrane during rotation.

[0027] It is worth noting that, see Figure 3 The fixing groove 21 has notches 22 on both sides, and the two notches 22 are symmetrically distributed on both sides of the fixing groove 21. The notches 22 make it easy for people to hold and insert the speaker, and thus make it easy for people to take the speaker out of the fixing groove 21.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
