Description

Technical Field

[0001] This utility model relates to the field of voice coil assembly technology, and in particular to an automatic assembly mechanism for a speaker voice coil. Background Technology

[0002] The voice coil is one of the most important components of a loudspeaker. When an alternating audio current passes through the voice coil, it generates an alternating current that varies with the audio frequency. This current cuts magnetic lines of force, producing mechanical vibration, which in turn causes the paper cone to vibrate and produce sound. Figure 1 As shown, during the assembly of the speaker, the tone gauge 2 needs to be inserted into the voice coil 2 in order to assemble the tone gauge 1 and the voice coil 2.

[0003] The existing speaker tone gauge assembly mechanism is assembled manually by operators. During the manual assembly process, the control precision of the insertion direction and force of the tone gauge is low. Therefore, problems such as the tone gauge not being inserted firmly, being inserted too tightly causing plastic deformation, and being inserted off-center are easy to occur. This not only results in high labor costs, high labor intensity, and low work efficiency, but also a low assembly yield. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the low yield and efficiency of manual assembly of voice coils and tone gauges in the prior art, thereby providing an automatic assembly mechanism for speaker voice gauges and voice coils.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1-5 As shown, the present invention provides an automatic assembly mechanism for a loudspeaker tone gauge and voice coil, comprising:

[0029] The accommodating mechanism includes a first carrier 8 and a second carrier 9, wherein the first carrier 8 and the second carrier 9 are respectively provided with accommodating slots 21 for accommodating the ring to be assembled and the tone gauge 1;

[0030] The clamping mechanism includes at least two sets of clamping components 10 and a first driving member 4. The at least two sets of clamping components 10 are respectively disposed on both sides of the first carrier 8, and the output end of the first driving member 4 is connected to the clamping components 10.

[0031] The crimping mechanism includes: a gripper 5, a second drive member 6, and a two-axis servo drive mechanism 3. The gripper 5 is disposed on one side of the tone gauge 1 to be assembled. The output end of the second drive member 6 is connected to the gripper 5, and the output end of the two-axis servo drive mechanism 3 is connected to the gripper 5.

[0032] The present invention discloses an automatic assembly mechanism for a speaker tone gauge 1. The voice coil 2 is placed in the receiving groove 21 of the first carrier 8, and the tone gauge 1 is placed in the receiving groove 21 of the second carrier 9. At least two sets of clamping components 10 clamp and fix the voice coil 2. The clamping components 10 are driven to move by the first driving member 4. Positioning is achieved using the first carrier 8 and the second carrier 9. Two sets of two-axis servo drive mechanisms 3 are activated to drive the grippers 5 to move laterally and longitudinally, bringing the grippers 5 to the tone gauge 1. The grippers 5 then clamp the tone gauge 1. The two-axis servo drive mechanisms 3 move the tone gauge 1 from the first carrier 8 to the second carrier 9. The two-axis servo drive mechanisms 3 are then activated again to drive the grippers 5. The grippers 5 clamp and press the tone gauge 1, inserting it into the voice coil 2, thus completing the assembly of the voice coil 2 and the tone gauge 1. This achieves automated assembly of the voice coil 2 and the tone gauge 1, with high component precision and minimal risk of damaging the voice coil 2.

[0033] Please see Figure 2 , Figure 3 As shown, the accommodating mechanism, clamping mechanism, and crimping mechanism are all disposed on the device body. The device body includes a base 19 and a bracket 20. The accommodating mechanism and clamping mechanism are disposed on the base 19, and the crimping mechanism is disposed on the bracket 20. The device body supports the accommodating mechanism, clamping mechanism, and crimping mechanism. The crimping mechanism is installed on the bracket 20 so that it is above the crimping mechanism and clamping mechanism. The accommodating mechanism and clamping mechanism are installed on the base 19 so that their heights are adapted, so that the two clamping components 10 can clamp the voice coil 2 from the side, and the movement of the crimping mechanism and the clamping components 10 does not interfere with each other.

[0034] Please see Figure 4 As shown, the base 19 is also provided with an adjustment assembly, which includes: a first support body 17 and a support 7 detachably connected to the first support body 17 on one side and connected to the first drive member 4 on the other side. With the first support body 17 and the support 7, the first drive member 4 is mounted on the support 7. By installing the support 7 at different positions on the first support body 17, the position of the first drive member 4 on the base 19 can be adjusted, which is convenient for clamping voice coils 2 of different sizes. Correspondingly, the first carrier 8 and the second carrier 9 can also be detachably mounted on the base 19. The first carrier 8, the second carrier 9 and the support 7 are installed by threaded connection, thereby realizing detachable connection.

[0035] Please see Figure 2 , Figure 5As shown, the two-axis servo drive mechanism 3 includes a horizontal servo drive component 301 and a vertical servo drive component 302. The horizontal servo drive component 301 is disposed on the bracket 20. The output ends of the vertical servo drive component 302 are connected to each other. The horizontal servo drive component 301 drives the vertical servo drive component 302 to move horizontally, and the vertical servo drive component 302 drives the gripper 5 to move vertically, thereby realizing the two-axis servo movement of the gripper 5, which facilitates the removal of the tone gauge 1 from the second carrier 9 to the first carrier 8 for pressing.

[0036] The two-axis servo drive mechanism 3 is a device capable of controlling and driving the movement of two axes. It consists of a servo motor, a servo driver, and a controller. An encoder or feedback device is used to monitor the position and speed of the motor in real time and feed these signals back to the servo driver and controller. The movement of the servo motor can be adjusted and controlled by commands sent by the controller. The servo driver is responsible for converting the commands sent by the controller into electrical signals that the motor can understand and execute. It receives control signals from the controller to achieve high-precision control of the motor's position, speed, and torque, facilitating the clamping of the tone gauge 1 at the first carrier 8 and the pressing of the tone gauge 1 into the voice coil 2 at the second carrier 9. The controller is responsible for receiving input signals, processing the motor control algorithm, generating control signals, and sending them to the servo driver. The controller can also communicate with external devices, such as human-machine interfaces and sensors, to better control the clamping assembly 10.

[0037] Please see Figure 4 As shown, a receiving component is also provided on the side of the clamping assembly 10 away from the gripper 5. Specifically, the receiving component includes: a second support body 15, and a slider 14 that is movably connected to the second support body 15 on one side and connected to the clamping assembly 10 on the other side. When the clamping assembly 10 clamps the voice coil 2, the longitudinal servo drive mechanism applies downward pressure to the voice coil 2, and the pressure direction is perpendicular to the direction of the piston rod of the cylinder. The slider 14 supports the clamping assembly 10 to prevent the piston rod of the cylinder from being crushed. At the same time, the slider 14 slides on the second support body 15, which can guide the clamping assembly 10 and improve the clamping accuracy. In some embodiments, the receiving component can also stop the gripper 5. By setting the slider 14 to support the support and setting a reasonable clamping position of the clamping assembly 10 on the voice coil 2, the assembly is completed when the end of the gripper 5 touches the clamping assembly 10.

[0038] In order for the gripper 5 to better hold the tone gauge 1, a second groove 16 corresponding to the voice coil 2 is also provided on the gripper 5. The second groove 16 is adapted to the end of the voice coil 2 to be assembled in the longitudinal direction. Similar to the first groove 13, the two grippers 5 are provided with symmetrical second grooves 16. The shape of the second groove 16 is also semi-circular. When pressing the tone gauge 1, the bottom wall of the second groove 16 abuts against the tone gauge 1.

[0039] The second driving component 6 uses a gripper 5 cylinder. The second driving component 6 is used to control the opening and closing of the gripper 5. It consists of a cylinder barrel, piston, piston rod and seal. When the gas in the cylinder barrel is pressurized, the piston moves forward and pushes the piston rod, thereby closing the gripper 5 to clamp the voice coil 2. When the gas in the cylinder barrel releases pressure, the piston moves backward and the gripper 5 opens. The gripper 5 is precisely controlled by controlling the pressure, flow and direction of the air source. The pressure and flow are controlled by controlling the on / off valve of the air source, and the direction of the cylinder is controlled by controlling the directional valve of the air source. In order to improve the automation level of the assembly mechanism, the gripper 5 cylinder can also be used with sensors, controllers and other devices to achieve more precise operation and control. The sensors are set at the second carrier 9 and the first carrier 8 to improve the clamping accuracy and crimping accuracy. The first driving component 4 uses two sets of cylinders arranged opposite each other. Its principle is similar to that of the first driving component 4, except that there are two sets of cylinders and they are symmetrically arranged, so it will not be described in detail.

[0040] Please see Figure 2 , Figure 4 As shown, a stop assembly is also provided between at least two sets of clamping components 10. Specifically, the stop assembly includes: a baffle 11 disposed between at least two sets of clamping components 10, and a stop member 12 connected to one end of the clamping component 10. The baffle 11 is disposed between the clamping components 10, and the stop member 12 is disposed on the body of the clamping component 10. When the clamping component 10 clamps the voice coil 2, the voice coil 2 will undergo slight deformation. Within the reasonable deformation range of the voice coil 2, the stop member 12 will not contact the baffle 11. When the clamping component squeezes the voice coil 2 to the boundary of the set deformation range, the baffle 11 will stop the stop member 12 to prevent the voice coil 2 from deforming further, which would prevent the track from being inserted into the voice coil 2 or even cause plastic deformation of the voice coil 2 itself. The baffle 11 can effectively protect the voice coil 2 by clamping it in the plane.

[0041] The clamping assembly 10 has a first groove 13 on the side near the first carrier 8. The shape of the first groove 13 is adapted to the voice coil 2 to be assembled. When the two clamping assemblies 10 clamp the voice coil 2, the voice coil 2 is inserted into the first groove 13 to limit the position of the voice coil 2. The voice coil 2 is generally circular. Therefore, the first groove 13 of the two sets of clamping assemblies 10 is preferably set as a corresponding semi-circle.

[0042] The base 19 has an installation groove 18 parallel to the line connecting the first carrier 8 and the second carrier 9. The first carrier 8 and the second carrier 9 are detachably connected to the installation groove 18. The first carrier 8 and the second carrier 9 can be installed at different positions on the installation groove 18. At the same time, the first carrier 8 and the second carrier 9 of different sizes can be easily replaced, which can adapt to the assembly of voice coils 2 and tone gauges 1 of different sizes.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
