Description

Technical Field

[0001] This utility model relates to the field of speaker unit assembly technology, and more specifically, to an automated assembly line for speaker units. Background Technology

[0002] The speaker unit (also called a "loudspeaker driver") is the core functional unit that makes up sound-producing devices such as speakers, headphones, and car audio systems. Simply put, it is the smallest independent component that converts electrical signals into sound signals.

[0003] In traditional speaker driver assembly, manual operation is largely relied upon. Operators must sequentially complete steps such as picking up and placing components, applying glue, attaching, and pressing. However, due to differences in the force and assembly angle of different operators, even using components of the same specifications, speaker drivers assembled by different batches or operators will still exhibit inconsistent sound quality. Downstream headphone manufacturers, speaker manufacturers, and other customers have extremely high requirements for the consistency of speaker driver sound quality. Manual assembly methods can no longer meet the demands of large-scale production and high quality. Therefore, an automated speaker driver assembly line that can achieve automated assembly and eliminate human error is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated assembly line for speaker units, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an automatic assembly line for speaker units, including a support frame, on which a conveying and assembly component is configured to realize the coordinated operation of conveying and assembling speaker unit parts;

[0006] The conveying assembly includes a conveyor belt installed on the top of the support frame for carrying parts and semi-finished products and realizing continuous conveying. A vibrating feeder is provided on one side of the conveyor belt for orderly arranging and feeding the loose parts of the horn unit. A feeding block is fixedly installed on the top of the support frame and between the conveyor belt and the vibrating feeder for connecting the vibrating feeder and the conveyor belt to realize the directional conveying of parts.

[0007] The feeding block has two guide grooves along its length for guiding the parts and preventing them from shifting during the conveying process. One end of the guide groove extends to the discharge end of the vibrating feeder and is connected to the discharge channel of the vibrating feeder.

[0008] The side of the feeding block away from the conveyor belt is fixedly mounted with a horizontally arranged sliding plate by a vertically set column. The bottom of the sliding plate is detachably mounted with a suction cup for adsorbing and grabbing parts from the feeding block and transferring them to the conveyor belt. Multiple transfer plates for placing speaker unit spring wave components and moving synchronously with the conveyor belt are arranged at intervals on the conveyor surface of the conveyor belt.

[0009] Optionally, in a possible implementation, a first electric push rod is fixedly installed on the side of the column near the slide plate, which is horizontally arranged and used to drive the slide plate to reciprocate in the horizontal direction. The output end of the first electric push rod is fixedly connected to the side wall of the slide plate. A second electric push rod is fixedly installed on the top of the slide plate, which is vertically arranged and used to drive the slide plate to rise and fall in the vertical direction. The fixed end of the second electric push rod is fixedly connected to the column through a bracket, and the output end is fixedly connected to the top of the slide plate. A horizontally arranged electric slide rail is fixedly installed on the side of the conveyor belt away from the vibrating feeder and along the length of the conveyor belt. A glue applicator is slidably connected on the electric slide rail for applying glue to the speaker unit components and whose position can be adjusted along the length of the electric slide rail. The glue outlet of the glue applicator is set towards the conveyor belt and extends directly above the conveyor belt to ensure that the glue application can be accurately applied to the components on the conveyor belt transfer plate. A support plate for supporting the auxiliary structure of the glue applicator is fixedly installed on the side of the electric slide rail near the conveyor belt. The support plate is arranged parallel to the electric slide rail.

[0010] Optionally, in a possible implementation, the end of the pallet away from the electric slide rail extends directly above the conveyor belt.

The third electric push rods are arranged vertically downward. The output ends of the two third electric push rods are fixedly installed with pressure plates to increase the contact area with the parts and avoid damaging the parts. The pressure plates are made of elastic material, and the lower surface of the pressure plates is parallel to the upper surface of the transfer plate. When the third electric push rod drives the pressure plates to descend, the pressure plates can fit tightly against the spring wave assembly or assembled parts on the transfer plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] Driven by the coordinated action of the first and second electric push rods, the suction cup can move horizontally and vertically, ensuring that components such as the voice coil and magnet can be precisely aligned with the preset position of the spider assembly, thus avoiding the problem of misalignment during manual placement.

[0013] The pressure output by the third electric push rod can be preset according to the material of the parts. Combined with the buffering effect of the elastic silicone pressure plate, it can ensure that the glue is fully soaked and bonded, and avoid the deformation of the components caused by the sudden increase or decrease of the pressure when pressing manually, thus ensuring the accuracy and quality of assembly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses an automated assembly line for speaker units, which aims to solve the problems of poor sound quality consistency and low production efficiency in the prior art of manually assembling speaker units.

[0021] Specifically, as shown in the attached document Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the automatic assembly line for speaker units includes a support frame 1, which is made of stainless steel and has adjustable support feet at the bottom to ensure the stability of the overall equipment.

[0022] The support frame 1 is equipped with a conveyor assembly component, which is the core structure for realizing the automated assembly of the speaker unit. Specifically, it includes a conveyor belt 2, a vibrating feeder 3, and a feeding block 4.

[0023] The conveyor belt 2 is mounted on the top of the support frame 1 via a drive motor and transmission rollers. The conveying surface of the conveyor belt 2 is made of wear-resistant rubber material, and multiple transfer plates 8 are spaced along its length. The transfer plates 8 are rectangular plastic plates used to place the wave assembly 9 of the speaker unit. They move synchronously with the conveyor belt 2 to realize the continuous conveying of the wave assembly 9.

[0024] A vibrating feeder 3 is installed on the left side of the conveyor belt 2. The vibrating feeder 3 adopts an electromagnetic vibration structure and has a spiral feeding track inside. It can arrange the scattered components of the speaker, such as voice coils and magnets, placed in its hopper in an orderly manner along the spiral track through vibration and transport them to the discharge end. A feeding block 4 is fixedly installed on the top of the support frame 1, between the conveyor belt 2 and the vibrating feeder 3, by welding. The feeding block 4 is a rectangular metal block, and its length direction is consistent with the width direction of the conveyor belt 2.

[0025] As attached Figure 3 As shown, two guide grooves 5 are formed along the length of the feeding block 4. The cross-sectional shape of the guide grooves 5 is adapted to the shape of the parts to be conveyed. In this embodiment, the guide grooves 5 are U-shaped grooves to ensure that the parts can pass smoothly without deviation. The left end of the guide groove 5 extends to the discharge end of the vibrating feeder 3 and is connected to the discharge channel of the discharge end of the vibrating feeder 3, so that the parts output by the vibrating feeder 3 can directly enter the guide grooves 5.

[0026] A sliding plate 6 is fixedly installed on the left side of the feeding block 4 via a vertically set column. The column is a stainless steel cylinder, with its bottom welded to the support frame 1 and its top connected to a horizontally arranged bracket by bolts. The sliding plate 6 is a rectangular metal plate located above the feeding block 4. A suction cup 7 is installed at the bottom of the sliding plate 6 via a threaded connection. The suction cup 7 is a vacuum suction cup, connected to an external vacuum pump, which can generate negative pressure to adsorb components.

[0027] To enable the movement of the slide plate 6 and suction cup 7, a first electric push rod 10 is fixedly installed on the right side of the column. The first electric push rod 10 is horizontally arranged and is model XTL100. Its output end is fixedly connected to the left side wall of the slide plate 6 via a coupling, which can drive the slide plate 6 to move left and right in the horizontal direction, realizing the position switching of the suction cup 7 between the feeding block 4 and the conveyor belt 2. A second electric push rod 11 is fixedly installed on the top of the slide plate 6. The second electric push rod 11 is vertically arranged and is also model XTL100. Its fixed end is connected to the top of the column via a bracket, and its output end is fixedly connected to the top of the slide plate 6 via bolts, which can drive the slide plate 6 to move up and down in the vertical direction, realizing the lifting and lowering of the suction cup 7, and completing the part gripping and placement action.

[0028] As attached Figure 1 Appendix Figure 2As shown, an electric slide rail 12 is fixedly installed on the right side of the conveyor belt 2 along its length. The electric slide rail 12 uses a linear module, model KK86, and the slider can reciprocate along the length of the slide rail. A glue applicator 13 is bolted to the slider of the electric slide rail 12. The glue applicator 13 adopts a dispensing structure, with its glue outlet facing the conveyor belt 2 and extending directly above the conveyor belt 2 to ensure precise application of glue to the surface of the horn assembly 9 or the parts to be assembled. The glue applicator 13 is driven by the electric slide rail 12 to adapt to the glue application position requirements of different specifications of horn units.

[0029] A stainless steel plate is fixedly installed on the left side of the electric slide rail 12, parallel to the electric slide rail 12, extending directly above the conveyor belt 2 and located downstream of the glue outlet of the glue applicator 13, ensuring that the parts after the glue application process can move with the conveyor belt 2 to the area below the plate. Two third electric push rods 14 are fixedly installed at intervals along the length of the bottom of the plate. The third electric push rods 14 are arranged vertically downwards, and their output ends are fixedly fitted with pressure plates 15 by bolts. The pressure plates 15 are made of silicone material, and their dimensions are adapted to the dimensions of the spring assembly 9 on the transfer plate 8. When the third electric push rods 14 drive the pressure plates 15 to descend, the pressure plates 15 can gently and tightly press against the joint between the spring assembly 9 and the parts to be bonded, ensuring a firm bond while avoiding damage to the parts.

[0030] The specific working principle is as follows: the spring assembly 9 of the speaker unit is placed one by one on the transfer plate 8 of the conveyor belt 2, the conveyor belt 2 is started, and the transfer plate 8 moves with the conveyor belt 2 towards the glue applicator 13; at the same time, other loose parts of the speaker unit, such as the voice coil, are put into the hopper of the vibrating feeder 3, the vibrating feeder 3 is started, and the parts are arranged in an orderly manner along the spiral track by vibration and conveyed to the guide groove 5 of the feeding block 4.

[0031] When there are parts in the guide groove 5, the second electric push rod 11 is activated, driving the slide plate 6 to descend, so that the suction cup 7 contacts the upper surface of the parts. The external vacuum pump is activated, and the suction cup 7 generates negative pressure to adsorb the parts. Then the second electric push rod 11 drives the slide plate 6 to rise to the set height, and the first electric push rod 10 is activated, driving the slide plate 6 to move towards the conveyor belt 2. When the suction cup 7 moves directly above the transfer plate 8, the first electric push rod 10 stops moving. The second electric push rod 11 drives the slide plate 6 to descend again, placing the parts on the spring assembly 9. The vacuum pump stops working, the suction cup 7 releases the parts, and the parts transfer is completed.

[0032] The conveyor belt 2 continues to run, transporting the transfer plate 8 containing the parts and the spring assembly 9 to the bottom of the glue applicator 13. According to the assembly requirements, the position of the glue applicator 13 is adjusted by the electric slide rail 12 so that the glue outlet of the glue applicator 13 is aligned with the position to be glued. The glue applicator 13 starts and applies glue to the joint between the parts and the spring assembly 9. After the glue application is completed, the conveyor belt 2 continues to transport the transfer plate 8.

[0033] When the transfer plate 8 after applying the adhesive moves to the bottom of the pallet, the conveyor belt 2 stops moving, the third electric push rod 14 starts, and drives the pressure plate 15 to descend until the pressure plate 15 presses tightly against the joint between the component and the spring assembly 9, maintaining a tight state to ensure that the adhesive is fully adhered; then the third electric push rod 14 drives the pressure plate 15 to rise and reset, the conveyor belt 2 starts again, and transports the semi-finished speaker unit that has completed the initial assembly to the next process. This cycle is repeated to realize the continuous automated assembly of the speaker unit.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
