Description

Technical Field

[0001] The present invention relates to the technical field of loudspeaker production, and specifically to an automatic loudspeaker assembly device. Background Art

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes its paper cone or diaphragm to vibrate and resonate with the surrounding air to produce sound. The performance of the loudspeaker has a great impact on the sound quality. The loudspeaker is the weakest component in audio equipment, but it is also the most important component for the sound effect. During the production of the loudspeaker, its components need to be assembled.

[0003] For example, the invention with the publication number CN110725840B discloses an assembly device for loudspeaker production. This invention can automatically perform the assembly operation of the loudspeaker, and can assemble two loudspeakers simultaneously each time, greatly improving the production efficiency of the loudspeaker. The front cover limiting component can limit the two front covers of the loudspeakers on the carrier simultaneously. Through the diaphragm pressing mechanism, the automatic feeding of two diaphragms can be realized automatically, without the operator manually feeding the diaphragms one by one. Through the automatic dispensing mechanism, the dispensing operation of the loudspeaker components and the diaphragms can be realized to solve the technical problems of low automatic assembly efficiency of the loudspeaker and assembly failure caused by manual feeding of the diaphragms in the prior art. However, in the actual use process of this type of equipment, due to the setting of multiple groups of front cover limiting components, and each front cover limiting component needs to be controlled by a separate drive motor, the problem of increasing the operation and use cost of the equipment is caused.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic loudspeaker assembly device is proposed. Summary of the Invention

[0016] The present invention provides a loudspeaker automatic assembly device, which has the following beneficial effects:

[0017] 1. When the motor drives the cam to rotate through the synchronous shaft in the present invention, it will push the sliding column to drive the rotating seat to drive the carrier table to rotate, so as to feed the loudspeaker front cover. During this process, the limiting strip will limit the bottom of the sliding rod to move it upward, so as to drive the slider to slide on the top of the carrier table through the connecting rod, so that the movable clamping plate moves towards the fixed clamping plate, and the loudspeaker front cover can be automatically clamped. And after the workpiece is assembled, when the workpiece moves out of the press-fitting station, the sliding rod will be located in the recess of the limiting strip. At this time, the reset spring will push the sliding rod downward under the limitation of the limiting frame, and at this time, the slider can be driven to move through the connecting rod, so that the movable clamping plate is separated from the workpiece, and the positioning of the workpiece is automatically released, so as to perform the picking and blanking operation on the workpiece. Therefore, during the operation process, the clamping state of the workpiece can be automatically controlled without single control, simplifying the steps during the operation and making it more convenient to use.

[0018] 2. During the process of the synchronous shaft driving the cam to rotate, the present invention also drives the driving wheel to rotate, thereby driving the lifting seat to slide up and down under the limitation of the limiting bracket through the driving rod. At the same time, when the flat part of the cam is located between the sliding columns, with the rotation of the synchronous shaft, the carrying platform will not rotate, and the carrying platform can be positioned to avoid rotation deviation. During this process, with the rotation of the synchronous shaft, the lifting seat will move downward, making the end of the glue outlet pipe located at the top of the front cover of the speaker. When the lifting seat moves upward, the inclined surface on the cam will fit with the sliding column, thereby driving the carrying platform to rotate through the rotating seat. At this time, due to the high position of the lifting seat, it will not interfere with the movement of the workpiece. Therefore, during the conveying process, the height of the glue outlet pipe can be automatically controlled, and the limiting plate can be used to limit the lowest height when the hanging bracket moves downward, so that the limiting plate can maintain a certain time at the lowest point position during the up and down reciprocating movement of the lifting seat for glue coating operation.

[0019] 3. When the limiting plate blocks the downward movement of the hanging bracket, with the downward movement of the lifting seat, the distance between the hanging bracket and the lifting seat will become shorter, causing the conveying pipe to slide inside the fixed cylinder. At this time, the glue in the fixed cylinder will squeeze the leather cup, causing it to open and tightly adhere to the outside of the fixed cylinder to reach a sealed state. At this time, the glue will enter the fixed box through the one-way valve and flow out from the lower glue outlet pipe, enabling automatic glue coating operation. When the lifting seat moves upward, the buffer spring will support between the lifting seat and the hanging bracket, increasing the distance between them. At this time, due to the one-way valve being in a closed state, the glue above the leather cup will squeeze the leather cup to make it contract, forming a gap with the fixed cylinder, and the glue in the glue storage tank will automatically replenish into the fixed cylinder through the conveying pipe, enabling the glue feeding assembly to work repeatedly.

[0020] 4. When the distance between the hanging bracket and the lifting seat becomes shorter, the lifting seat will also drive the rack to move on one side of the driving gear. During this process, the hanging bracket will also limit one side of the rack to enhance its stability during movement. Therefore, when the rack drives the driving gear to rotate, it will drive the rotating plate to rotate through the rotating shaft, the first bevel gear, the second bevel gear, and the transmission shaft, so that during the glue coating process, the glue outlet pipe can move along the edge of the front cover of the speaker. At the same time, when the distance between the hanging bracket and the lifting seat is reduced to the shortest, the rotating plate just rotates one circle, so that the glue can be evenly applied to the edge of the front cover of the speaker, which is beneficial to improving the subsequent bonding effect.

[0030] Please refer to Figure 1 , Figures 4 to 7, the end of the synchronization shaft 3 is connected with a dispensing assembly 9. The dispensing assembly 9 includes a driving wheel 901, a driving rod 902, a lifting seat 903 and a limiting bracket 904. The end of the synchronization shaft 3 is connected with the driving wheel 901, and one side of the driving wheel 901 is rotatably connected with the driving rod 902. The top of the driving rod 902 is rotatably connected with the lifting seat 903, and the outside of the lifting seat 903 is slidably connected with the limiting bracket 904. And the limiting bracket 904 is fixedly connected with the workbench 1. The dispensing assembly 9 further includes a limiting plate 905, a limiting rod 906, a buffer spring 907 and a hanging bracket 908. A limiting plate 905 is arranged on one side of the limiting bracket 904. The two ends inside the lifting seat 903 are slidably connected with the limiting rod 906, and the lower end outside of the limiting rod 906 is sleeved with the buffer spring 907. And the bottom of the limiting rod 906 is fixed with the hanging bracket 908. The dispensing assembly 9 further includes a fixed box 909, a rotating plate 910 and a glue outlet pipe 911. The bottom of the hanging bracket 908 is provided with the fixed box 909. And the two ends of the bottom of the fixed box 909 are rotatably connected with the rotating plate 910. The bottom of the rotating plate 910 is connected with the glue outlet pipe 911. A glue feeding assembly 10 is arranged at one end of the lifting seat 903. The glue feeding assembly 10 includes a glue storage tank 1001, a conveying pipe 1002 and an O-ring 1003. The top of one end of the lifting seat 903 is fixed with the glue storage tank 1001. And the bottom of the glue storage tank 1001 is connected with the conveying pipe 1002. And the lower end outside of the conveying pipe 1002 is sleeved with the O-ring 1003. The glue feeding assembly 10 further includes a connecting frame 1004, a leather cup 1005, a fixed cylinder 1006 and a one-way valve 1007. The bottom of the conveying pipe 1002 is provided with the connecting frame 1004. And the bottom of the connecting frame 1004 is fixed with the leather cup 1005. The outside of the leather cup 1005 is slidably connected with the fixed cylinder 1006. And the fixed cylinder 1006 is fixedly connected with the hanging bracket 908. And the fixed cylinder 1006 is slidably connected with the conveying pipe 1002. The bottom of the fixed cylinder 1006 is provided with the one-way valve 1007. And the one-way valve 1007 is communicated with the fixed box 909;

[0031] The specific operation is as follows: First, place the front cover of the speaker between the movable clamping plate 807 and the fixed clamping plate 808 at the front end of the loading platform 7. Then, start the motor 2, which drives the cam 4 to rotate through the synchronous shaft 3. The cam 4 will push the sliding column 5, causing the rotating seat 6 to drive the loading platform 7 to rotate, so as to feed the front cover of the speaker. During this process, the limiting strip 801 will limit the bottom of the sliding rod 803, causing it to move upward. Thus, through the connecting rod 805, the slider 806 is driven to slide on the top of the loading platform 7, making the movable clamping plate 807 move towards the fixed clamping plate 808, and the front cover of the speaker can be automatically clamped. Moreover, during the process of the synchronous shaft 3 driving the cam 4 to rotate, the driving wheel 901 will also be driven to rotate, so as to drive the lifting seat 903 to slide up and down under the limitation of the limiting bracket 904 through the driving rod 902. At the same time, when the flat part of the cam 4 is between the sliding columns 5, as the synchronous shaft 3 rotates at this time, the loading platform 7 will not be driven to rotate, and the loading platform 7 can also be positioned to prevent it from rotating and shifting. During this process, as the synchronous shaft 3 rotates, the lifting seat 903 will move downward. At this time, the limiting plate 905 is used to limit the lowest height when the hanging bracket 908 moves downward, so that the end of the glue outlet pipe 911 is located at the top of the front cover of the speaker. And as the lifting seat 903 continues to move downward, the distance between the hanging bracket 908 and the lifting seat 903 will become shorter, causing the conveying pipe 1002 to slide inside the fixed cylinder 1006. At this time, the glue in the fixed cylinder 1006 will squeeze the leather cup 1005, causing it to open and closely adhere to the outside of the fixed cylinder 1006 to reach a sealed state. At this time, the glue will enter the fixed box 909 through the one-way valve 1007 and flow out from the lower glue outlet pipe 911, so that the glue application operation can be automatically carried out. Subsequently, when the lifting seat 903 moves upward, the buffer spring 907 will support between the lifting seat 903 and the hanging bracket 908, increasing the distance between them. At this time, since the one-way valve 1007 is in a closed state, the glue above the leather cup 1005 will squeeze the leather cup 1005 to make it contract, thus forming a gap with the fixed cylinder 1006. The glue in the glue storage tank 1001 will automatically replenish into the fixed cylinder 1006 through the conveying pipe 1002. And after the lifting seat 903 moves upward, the inclined surface on the cam 4 will fit with the sliding column 5, so as to drive the loading platform 7 to rotate through the rotating seat 6. At this time, since the lifting seat 903 is at a relatively high position, it will not interfere with the movement of the workpiece. Subsequently, when the workpiece moves out of the pressing station, the sliding rod 803 will be located in the concave part of the limiting strip 801. At this time, the return spring 804 will push the sliding rod 803 under the limitation of the limiting frame 802, causing it to move downward. At this time, the slider 806 can be driven to move through the connecting rod 805, separating the movable clamping plate 807 from the workpiece and automatically releasing the positioning of the workpiece, so as to carry out the operation of picking up and discharging the workpiece. Therefore, during the operation process, the clamping state of the workpiece can be automatically controlled without single control.

[0032] Please refer to Figure 1 、 Figure 4and Figure 5 , at both ends of the bottom of the lifting seat 903, there are rotation components 11 connected. The rotation components 11 include racks 1101, drive gears 1102 and rotating shafts 1103. Racks 1101 are symmetrically arranged at both ends of the bottom of the lifting seat 903, and a drive gear 1102 is meshed with one side of the rack 1101. A rotating shaft 1103 is connected to one side of the drive gear 1102, and the rotating shaft 1103 is rotationally connected to the fixed box 909. The rotation components 11 further include a first bevel gear 1104, a second bevel gear 1105 and a transmission shaft 1106. The end of the rotating shaft 1103 is connected to the first bevel gear 1104, and the end of the first bevel gear 1104 is connected to the second bevel gear 1105. A transmission shaft 1106 is fixed to the bottom of the second bevel gear 1105, and the transmission shaft 1106 is fixedly connected to the rotating plate 910. At the rear end of the workbench 1, there is a press-fitting component 12 arranged. The press-fitting component 12 includes a storage rack 1201, a first cylinder 1202 and a translation rack 1203. The storage rack 1201 is arranged at the rear part of the workbench 1, and a first cylinder 1202 is fixed to one side of the upper part of the storage rack 1201, and one end of the first cylinder 1202 is connected to the translation rack 1203. The press-fitting component 12 further includes a second cylinder 1204, a lifting rack 1205, a pneumatic suction cup 1206 and a pneumatic gripper 1207. The second cylinder 1204 is fixed to the top of the translation rack 1203, and the bottom of the second cylinder 1204 is connected to the lifting rack 1205. A pneumatic suction cup 1206 is arranged at one end of the lifting rack 1205, and a pneumatic gripper 1207 is arranged at the other end of the lifting rack 1205;

[0033] The specific operations are as follows. During the glue application process, when the distance between the hanging bracket 908 and the lifting seat 903 becomes shorter, the lifting seat 903 will also drive the rack 1101 to move on one side of the driving gear 1102. During this process, the hanging bracket 908 will also limit one side of the rack 1101 to enhance its stability during movement. Therefore, when the rack 1101 drives the driving gear 1102 to rotate, it will drive the rotating plate 910 to rotate through the rotating shaft 1103, the first bevel gear 1104, the second bevel gear 1105, and the transmission shaft 1106. So that during the glue application process, the glue outlet pipe 911 can move along the edge of the speaker front cover. At the same time, when the distance between the hanging bracket 908 and the lifting seat 903 is reduced to the shortest, the rotating plate 910 just rotates one circle, so that the glue can be evenly applied to the edge of the speaker front cover, which is beneficial to improving the effect during subsequent bonding. After that, when the workpiece moves to the press-fitting assembly 12, the first cylinder 1202 can control the horizontal position of the translation frame 1203 so that the lifting frame 1205 is located at the top of the storage rack 1201. At this time, the second cylinder 1204 drives the lifting frame 1205 to move down, and the pneumatic suction cup 1206 can suck the diaphragm placed on the top of the storage rack 1201, and the pneumatic gripper 1207 can also grab the accessories. Subsequently, through the first cylinder 1202 and the second cylinder 1204, the diaphragm and the accessories can be press-fitted onto the speaker front cover to complete the assembly operation of the speaker components.

[0034] In summary, for this automatic speaker assembly equipment, when in use, first place the speaker front cover between the movable clamping plate 807 and the fixed clamping plate 808 at the front end of the loading platform 7. Then start the motor 2, which drives the cam 4 to rotate through the synchronous shaft 3. The cam 4 will push the sliding column 5, causing the rotating seat 6 to drive the loading platform 7 to rotate, so as to feed the speaker front cover. During this process, the limiting strip 801 will limit the bottom of the sliding rod 803, causing it to move upward. Thus, the connecting rod 805 drives the slider 806 to slide on the top of the loading platform 7, making the movable clamping plate 807 move towards the fixed clamping plate 808 to automatically clamp the speaker front cover. Next, the synchronous shaft 3 will also drive the driving wheel 901 to rotate, thereby driving the lifting seat 903 to slide up and down under the limitation of the limiting bracket 904 through the driving rod 902. And when the flat part of the cam 4 is between the sliding columns 5, at this time, with the rotation of the synchronous shaft 3, it will not drive the loading platform 7 to rotate, and at the same time, it can also position the loading platform 7. During this process, with the rotation of the synchronous shaft 3, the lifting seat 903 will move downward. At this time, the limiting plate 905 is used to limit the lowest height when the hanging bracket 908 moves downward, so that the end of the glue outlet pipe 911 is located at the top of the speaker front cover. And as the lifting seat 903 continues to move downward, the distance between the hanging bracket 908 and the lifting seat 903 will become shorter, causing the conveying pipe 1002 to slide inside the fixed cylinder 1006. At this time, the glue liquid inside the fixed cylinder 1006 will squeeze the leather cup 1005, causing it to open and closely adhere to the outside of the fixed cylinder 1006 to reach a sealed state. The glue liquid will enter the fixed box 909 through the one-way valve 1007 and flow out from the lower glue outlet pipe 911. Secondly, the lifting seat 903 will also drive the rack 1101 to move on one side of the driving gear 1102, thereby driving the driving gear 1102 to rotate. Then, it will drive the rotating plate 910 to rotate through the rotating shaft 1103, the first bevel gear 1104, the second bevel gear 1105 and the transmission shaft 1106. So that during the glue application process, the glue outlet pipe 911 can move along the edge of the speaker front cover. At the same time, when the distance between the hanging bracket 908 and the lifting seat 903 is reduced to the shortest, the rotating plate 910 just rotates one circle, so as to evenly apply the glue liquid on the edge of the speaker front cover. Then, when the lifting seat 903 moves upward, the buffer spring 907 will support between the lifting seat 903 and the hanging bracket 908. At this time, since the one-way valve 1007 is in a closed state, the glue liquid above the leather cup 1005 will squeeze the leather cup 1005 to make it contract inward, thus forming a gap with the fixed cylinder 1006. The glue liquid in the glue storage tank 1001 will automatically replenish into the fixed cylinder 1006 through the conveying pipe 1002. And after the lifting seat 903 moves upward, the inclined surface on the cam 4 will fit with the sliding column 5, thereby driving the loading platform 7 to rotate through the rotating seat 6. At this time, since the lifting seat 903 is at a higher position, it will not interfere with the movement of the workpiece. Then, when the workpiece moves to the press-fitting assembly 12, the first cylinder 1202 can control the horizontal position of the translation frame 1203, so that the lifting frame 1205 is located on the top of the storage rack 1201.At this time, the second cylinder 1204 drives the lifting frame 1205 to move downward, so that the pneumatic suction cup 1206 can suck the diaphragm placed on the top of the storage rack 1201, and the pneumatic gripper 1207 can also grasp the pre-placed accessories. Subsequently, through the first cylinder 1202 and the second cylinder 1204, the diaphragm and the accessories can be press-fitted onto the front cover of the speaker, completing the assembly operation of the speaker components.
