Description

Tail wire removal equipment for diaphragm assemblies Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically a tail wire taking device for diaphragm assemblies. Background Technology

[0002] The diaphragm assembly is one of the important components of a loudspeaker. As shown in Figure 1, the diaphragm assembly includes a voice coil 10 and a diaphragm 20 covering the voice coil 10. The voice coil 10 is usually made of copper wire wound in a preset shape, with a portion of tail wire left at both ends of the copper wire. After the voice coil 10 is wound, the tail wires at both ends of the copper wire are cut off respectively (Figure 1 shows the voice coil 10 with the tail wires cut off) to meet the assembly and performance requirements of the voice coil 10.

[0003] As manufacturers demand higher production levels and efficiency, more and more are using automated wire-cutting equipment to remove the tail wire from the voice coil. Typically, the tail wire removed by this equipment remains inside the carrier holding the diaphragm assembly. How to remove the tail wire from the carrier and prevent it from being mistakenly installed into the loudspeaker is a problem that those skilled in the art need to consider and solve. Summary of the Invention

[0004] To overcome the deficiencies in the prior art, embodiments of the present invention provide a tail wire extraction device for a diaphragm assembly, which solves the above-mentioned problems.

[0007] A pressing mechanism is disposed above the conveying mechanism, and includes a first mounting plate and a pressing assembly disposed on the first mounting plate;

[0008] A lifting mechanism is located below the pressing mechanism. When the carrier is conveyed to the lifting mechanism by the conveying mechanism, the lifting mechanism lifts the carrier upward so that the diaphragm assembly inside the carrier abuts against the pressing assembly.

[0009] An opening mechanism is provided above or below the conveying mechanism to open the tail wire clamp so that the tail wire clamp releases the tail wire;

[0010] A tail wire retrieval mechanism is disposed above the conveying mechanism, including a drive unit and a clamping unit disposed on the drive unit, the clamping unit being used to clamp the tail wire.

[0011] Specifically, the tail wire clamp includes a movable part rotatably connected to the support plate, a fixed part fixedly connected to the support plate, and a first compression spring fixed to the support plate. One end of the movable part is connected to the first compression spring, and the other end of the movable part cooperates with the fixed part to clamp the tail wire.

[0012] Specifically, the movable component has a first wall surface on the side facing the fixed component, and the fixed component has a second wall surface on the side facing the movable component. The gap between the first wall surface and the second wall surface is smaller than the outer diameter of the tail wire.

[0013] Specifically, the clamping mechanism is located below the conveying mechanism and includes a clamping cylinder and a push rod on the output shaft of the clamping cylinder. The bearing plate is provided with a through hole for the push rod to pass through and push the movable part upward.

[0014] Specifically, the movable member has a protrusion extending toward the push rod at the point of contact with the push rod.

[0015] Specifically, the drive unit is a three-axis module, and the gripping unit includes a second mounting plate connected to the three-axis module, a gripper cylinder connected to the second mounting plate, and a gripper connected to the output shaft of the gripper cylinder.

[0017] Specifically, the pressing assembly includes a connector fixed to the first mounting plate, a second compression spring connected to the connector, and a pressing head connected to the end of the second compression spring away from the connector, wherein the pressing head is used to abut against the diaphragm assembly.

[0018] Specifically, the pressing mechanism further includes a bracket connected to the conveying mechanism and a limiting plate disposed on the bracket. The first mounting plate is connected to the limiting plate, and the limiting plate is used to limit the bearing plate of the carrier.

[0019] Specifically, the tail wire collection device for the diaphragm assembly further includes a waste recycling container for receiving the tail wire.

[0020] The present invention has at least the following beneficial effects: The tail wire removal device for the diaphragm assembly in this embodiment can automatically clamp and remove the cut voice coil tail wire, avoiding the tail wire remaining on the clamp and being mistakenly installed into the speaker. Moreover, since the entire tail wire removal process is completed automatically by the equipment, it is conducive to the automation of the process, which not only improves production efficiency but also saves labor costs.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] As shown in Figures 2 to 5, the tail wire taking device for the sound diaphragm assembly in this embodiment mainly includes: a conveying mechanism 1, a pressing mechanism 2, a lifting mechanism 3, a clamping mechanism 4, and a tail wire taking mechanism.

[0037] The conveying mechanism 1 generally includes two profiles arranged opposite each other and two conveyor belts respectively arranged on the two profiles. The conveying mechanism 1 is used to transport the carrier carrying the diaphragm assembly. The carrier includes a support plate 100 and a tail wire clamp 200. The support plate 100 has a receiving cavity for accommodating the diaphragm assembly. The tail wire clamp 200 is located on the support plate 100 for clamping the tail wire of the diaphragm assembly. Specifically, the tail wire clamp 200 can be arranged on both sides of the receiving cavity. The position of the tail wire clamp 200 generally corresponds to the position of the tail wire on the voice coil 10. As shown in Figure 1, the excess tail wire of the voice coil 10 has been cut off (by the previous station equipment of this device). Before the tail wire of the voice coil 10 is cut off, the two tail wires are placed on the tail wire clamps 200 on both sides, so that the tail wire clamps 200 clamp one side of the tail wire respectively. After the tail wire is cut off, the tail wire clamps 200 have not yet opened and continue to hold the tail wire in the state of clamping. The tail wire is fed into the tail wire picking device of this embodiment in this state. The tail wire clamp 200 ensures that the tail wire is cut at a precise position, while preventing waste material from jumping out during the cutting process.

[0038] The pressing mechanism 2 is located above the conveying mechanism 1, and includes a first mounting plate 21 and a pressing assembly 22 disposed on the first mounting plate 21. The pressing assembly 22 is mainly used to press the diaphragm 20 (or other parts of the diaphragm assembly) during the tail wire removal process to prevent the diaphragm 20 from being carried away from the carrier's receiving cavity during the tail wire removal process, which would cause the diaphragm assembly to be poorly positioned.

[0039] The lifting mechanism 3 is located below the pressing mechanism 2. When the carrier is conveyed to the lifting mechanism 3 by the conveying mechanism 1, the lifting mechanism 3 lifts the carrier upward so that the diaphragm assembly inside the carrier abuts against the pressing assembly 22.

[0040] The clamping mechanism 4 is located above or below the conveying mechanism 1 and is used to open the tail wire clamp 200 so that the tail wire clamp 200 can release the tail wire so that the tail wire removal mechanism can remove the tail wire.

[0041] The tail wire retrieval mechanism is located above the conveying mechanism 1. It includes a drive unit 51 and a gripping unit 52 disposed on the drive unit 51. When the drive unit 51 drives the gripping unit 52 to move to the tail wire clamp 200 to grip the tail wire, the tail wire clamp 200 is opened to release the tail wire. Subsequently, the drive unit 51 drives the gripping unit 52 to leave the tail wire clamp 200 with the tail wire.

[0042] As shown in Figures 5 and 6 (Figure 6 mainly shows the structure of the tail wire clamp 200), the tail wire clamp 200 of this embodiment includes a movable member 210 rotatably connected to the support plate 100, a fixed member 220 fixedly connected to the support plate 100, and a first compression spring 230 fixedly connected to the support plate 100. Specifically, the movable member 210 is rotatably connected to the support plate 100 via a connecting shaft 240. One end of the movable member 210 is connected to the first compression spring 230, and the first compression spring 230 is in a pre-compressed state. The other end of the movable member 210 cooperates with the fixed member 220 to clamp the tail wire. More specifically, the movable member 210 has a first wall surface on the side facing the fixed member 220, and the fixed member 220 has a second wall surface on the side facing the movable member 210. There is a gap between the first wall surface and the second wall surface that is smaller than the outer diameter of the tail wire. Therefore, the first wall surface and the second wall surface can cooperate to clamp the tail wire.

[0043] As shown in Figures 7 and 8, the clamping mechanism 4 and the lifting mechanism 3 can be jointly arranged below the conveying mechanism 1. The clamping mechanism 4 and the lifting mechanism 3 can be interlocked, which helps to save space in their arrangement. The lifting mechanism 3 includes a lifting cylinder 31 and a top plate 32 connected to the output shaft of the lifting cylinder 31. The top plate 32 is used to lift the carrier upward. The clamping mechanism 4 includes an clamping cylinder 41 and a push rod 42 arranged on the output shaft of the clamping cylinder 41. The top plate 32 of the lifting mechanism 3 is provided with a clearance window 321 for the push rod 42 of the clamping mechanism 4 to lift upward. The carrier's bearing plate 100 is provided with a through hole 110 for the push rod 42 to pass through and lift the movable part 210 upward. When the push rod 42 lifts the movable part 210 upward, the gap between the first wall surface and the second wall surface increases, and the tail line is loosened. Preferably, the movable member 210 may have a protrusion 211 extending toward the push rod 42 at the point of contact with the push rod 42. When the push rod 42 contacts the protrusion 211, the movable member 210 will move upward, which helps to shorten the upward stroke of the push rod 42.

[0044] Referring again to Figure 7, the lifting cylinder 31 can be inverted, that is, the cylinder body is on top and the output shaft is below the cylinder body. A floating connecting plate 33 is connected to the output shaft of the lifting cylinder 31, and the floating connecting plate 33 is connected to the top plate 32 through multiple guide posts 34. Multiple push rods 42 of the clamping mechanism 4 are connected to the output shaft of the clamping cylinder 41 through the third mounting plate 43.

[0045] As shown in Figure 2, the drive unit 51 in this embodiment can be a common three-axis module. As shown in Figures 9 and 10, the gripping unit 52 includes a second mounting plate 521 connected to the three-axis module, a gripper cylinder 522 connected to the second mounting plate 521, and grippers 523 connected to the output shaft of the gripper cylinder 522. When the gripper cylinder 522 is running, it can drive the two sets of grippers 523 to open and close, realizing the gripping and releasing of the tail wire.

[0046] As shown in Figure 11, the pressing assembly 22 of this embodiment includes a connector 221 fixed to the first mounting plate 21, a second compression spring 222 connected to the connector 221, and a pressing head 223 connected to the end of the second compression spring 222 facing away from the connector 221. The second compression spring 222 is used to make the diaphragm 20 (or other parts of the diaphragm assembly) come into elastic contact when the pressing head 223 abuts against it, so as to avoid damage to the diaphragm 20 (diaphragm assembly) due to rigid contact with the pressing head 223. Further, as shown in Figure 4, the pressing mechanism 2 of this embodiment may also include a bracket 23 connected to the profile of the conveying mechanism 1 and a limiting plate 24 disposed on the bracket 23. The first mounting plate 21 of the pressing mechanism 2 is connected to the limiting plate 24. The limiting plate 24 is used to abut against the bearing plate 100 of the carrier when the carrier is lifted upward by the lifting mechanism 3. That is, it limits the upward movement of the bearing plate 100 to avoid the lifting cylinder 31 from going out of control and causing the carrier to move upward too much, thereby causing the product in the carrier to violently collide with the pressing component 22.

[0047] As shown in Figure 4, the tail wire retrieval device for the diaphragm assembly in this embodiment may also include a waste recycling container 6 disposed next to the conveying mechanism 1, which is used to receive the tail wire retrieval device.

[0048] The working process of the tail wire taking device for the diaphragm assembly in this embodiment is as follows: The carrier is conveyed by the conveying mechanism 1 to the position corresponding to the lifting mechanism 3. The lifting mechanism 3 lifts the carrier upward. The pressing mechanism 2 presses the diaphragm 20 (diaphragm assembly) with material. Then, the driving unit 51 drives the clamping unit 52 to run to the tail wire clamp 200 to clamp the tail wire. Next, the clamping mechanism 4 opens the tail wire clamp 200 on the carrier so that the tail wire clamp 200 releases the tail wire. Then, the driving unit 51 drives the clamping unit 52 to place the waste at the waste recycling container 6. At the same time, the clamping mechanism 4 releases the tail wire clamp 200, and the tail wire clamp 200 returns to the closed state.

[0049] In summary, the tail wire removal device for the diaphragm assembly in this embodiment can automatically clamp and remove the cut tail wire of the voice coil 10, preventing the tail wire from being left on the clamp and mistakenly installed into the speaker. Since the entire tail wire removal process is completed automatically by the equipment, it is conducive to the automation of the process, which not only improves production efficiency but also saves labor costs.

[0050] Specific embodiments have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this invention. Therefore, the content of this specification should not be construed as a limitation of this invention.
