Abstract
Description
Technical Field
[0001] This utility model relates to the field of voice coil assembly technology, specifically a station feeding device for a voice coil assembly line. Background Technology
[0002] The voice coil is the core driving component of a loudspeaker or linear motor. It is typically made of enameled wire wound into a toroidal coil, fixed to a diaphragm or mover, and placed in the magnetic field of a permanent magnet. When an audio current is applied, the voice coil reciprocates under the Lorentz force in the magnetic field, thereby causing the diaphragm to vibrate and produce sound or to achieve precise linear displacement. During the voice coil assembly process, the workpiece is transported to the assembly position via a conveyor belt.
[0003] In the prior art, patent announcement number CN118713411B discloses a voice coil motor, comprising: a mounting housing; a permanent magnet structure mounted on the mounting housing; a coil mounting structure mounted on the mounting housing; a bearing structure mounted on the mounting housing; and an elastic structure mounted on the mounting housing. During assembly, the permanent magnet structure needs to be installed into the housing.
[0004] A conveyor belt can smoothly and continuously move the housing to be assembled to the designated assembly station. Once the housing arrives precisely at the assembly station, a robotic arm can securely place the permanent magnet structure into the internal space of the housing. However, in actual operation, due to various uncontrollable factors, the housing may deviate to varying degrees while the conveyor belt is transporting it. This deviation not only interferes with the normal assembly process but also directly affects the alignment accuracy between the permanent magnet structure and the housing, thereby reducing the overall installation accuracy and product quality. Therefore, a station-feeding device for a voice coil assembly line is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a workstation feeding device for a voice coil assembly line to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a workstation feeding device for a voice coil assembly line, comprising an equipment base, with supporting feet fixedly installed at the four corners of the bottom of the equipment base, an equipment frame fixedly installed at the upper end of the equipment base, a double-line conveyor belt installed inside the equipment frame, a limiting mechanism installed on the double-line conveyor belt, the limiting mechanism comprising a mounting frame fixedly installed above the double-line conveyor belt and a clamping block fixedly installed on one side of the double-line conveyor belt, a lead screw slide fixedly installed on the mounting frame, a clamping plate fixedly installed on the lead screw slide, and the clamping plate and the clamping block being aligned front and back, and a driving mechanism installed below the double-line conveyor belt.
[0007] Preferably, the limiting mechanism further includes a first bracket and a second bracket fixedly installed below the double-line conveyor belt, with a stop block slidably installed on the first bracket and a lifting seat installed on the top of the second bracket.
[0008] Preferably, both the first bracket and the second bracket are connected to the bottom with bolts, and both the first bracket and the second bracket are fixedly installed on the equipment base by bolts.
[0009] Preferably, the lead screw slide is mounted above the double-line conveyor belt via a mounting bracket, the stop block is movably mounted in the middle of the double-line conveyor belt via a first bracket, and the lifting seat is movably mounted below the double-line conveyor belt via a second bracket.
[0010] Preferably, the driving mechanism includes a cylinder fixedly mounted on the equipment base and a positioning sleeve fixedly mounted on the stop block. A crossbeam is fixedly mounted at the output end of the cylinder. A first push rod is fixedly mounted at one end of the crossbeam. A spring seat is fixedly mounted at the upper end of the first push rod and is movably mounted inside the positioning sleeve. A return spring is installed inside the positioning sleeve. A second push rod is fixedly mounted at the other end of the crossbeam and is fixedly mounted at the upper end of the second push rod on the lifting seat.
[0011] Preferably, the positioning sleeve has a through hole at the bottom, through which the first push rod extends into the positioning sleeve.
[0012] Preferably, one end of the reset spring is connected to the top of the positioning sleeve, and the other end of the reset spring is connected to the spring seat. The crossbeam is movably installed below the double-line conveyor belt via a cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this application, when the workpiece carrier moves to the assembly station, the cylinder can be extended. After the cylinder extends, the stop block extends accordingly, thereby limiting the workpiece carrier from moving forward. At this time, the cylinder is extended again, which will drive the first push rod and the second push rod to continue moving upward. During the upward movement of the first push rod, the return spring is compressed; when the second push rod moves upward, it will drive the lifting seat to move upward, thereby pushing the workpiece carrier away from the double-line conveyor belt.
[0015] 2. In this application, after the lead screw slide is activated, it drives the clamping plate to move closer to the clamping block. Utilizing the clamping effect between the clamping plate and the clamping block, the workpiece carrier is fixed at the assembly station to facilitate assembly operations. After assembly, the clamping plate can be retracted, releasing the workpiece carrier. Subsequently, the cylinder can be retracted to reset the stop block and lifting seat. After the stop block and lifting seat are reset, the dual-line conveyor belt can continue to drive the workpiece carrier to move, thereby removing the assembled workpiece.
[0016] 3. After rotating the threaded rod, it will drive the connecting leg to move forward or backward. When the connecting leg moves forward, it will pull the extension plate out of the limiting slide groove, thereby increasing the surface area of the upper end of the lifting seat to support larger workpieces.

[0024] 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.
[0025] like Figure 1 and Figure 2As shown, this utility model provides a technical solution for a workstation feeding device for a voice coil assembly line, including an equipment base 1, with support legs 2 fixedly installed at the four corners of the bottom of the equipment base 1, an equipment frame 4 fixedly installed on the upper end of the equipment base 1, a double-line conveyor belt 3 installed inside the equipment frame 4, a limiting mechanism 5 installed on the double-line conveyor belt 3, and a driving mechanism 6 installed below the double-line conveyor belt 3. Through the cooperation of the limiting mechanism 5 and the driving mechanism 6, the workpiece can be quickly positioned, facilitating assembly operations.
[0026] like Figure 3 and Figure 4 As shown, the limiting mechanism 5 includes a mounting frame 501 fixedly installed above the double-track conveyor belt 3 and a clamping block 506 fixedly installed on one side of the double-track conveyor belt 3. A screw slide 502 is fixedly installed on the mounting frame 501, and a clamping plate 503 is fixedly installed on the screw slide 502. The clamping plate 503 and the clamping block 506 are aligned front and back. The limiting mechanism 5 also includes a first bracket 505 and a second bracket 508 fixedly installed below the double-track conveyor belt 3. A stop block 504 is slidably installed on the first bracket 505, and a lifting seat 507 is installed on the top of the second bracket 508. Bolts are connected to the bottom of both the first bracket 505 and the second bracket 508. Both the first bracket 505 and the second bracket 508 are fixedly installed on the equipment base 1 by bolts.
[0027] Specifically, after starting the lead screw slide 502, it will drive the clamping plate 503 to move closer to the clamping block 506. With the clamping action of the clamping plate 503 and the clamping block 506, the workpiece carrier can be fixed at the assembly station, which facilitates the assembly operation.
[0028] After assembly, the clamping plate 503 can be retracted, thereby releasing the workpiece carrier. Subsequently, the cylinder 607 is retracted, causing the stop block 504 and the lifting seat 507 to reset. After the stop block 504 and the lifting seat 507 have reset, the double-line conveyor belt 3 can continue to drive the workpiece carrier to move, thereby removing the assembled workpiece.
[0029] like Figure 4 and Figure 5 As shown, the drive mechanism 6 includes a cylinder 607 fixedly mounted on the equipment base 1 and a positioning sleeve 601 fixedly mounted on the stop block 504. A crossbeam 606 is fixedly mounted at the output end of the cylinder 607. A first push rod 604 is fixedly mounted at one end of the crossbeam 606. A spring seat 603 is fixedly mounted at the upper end of the first push rod 604, and the spring seat 603 is movably mounted inside the positioning sleeve 601. A reset spring 602 is installed inside the positioning sleeve 601. A second push rod 605 is fixedly mounted at the other end of the crossbeam 606, and the upper end of the second push rod 605 is fixedly mounted on the lifting seat 507. A through hole is opened at the bottom of the positioning sleeve 601, and the first push rod 604 extends into the positioning sleeve 601 through the through hole.
[0030] Specifically, when the workpiece carrier moves to the assembly station, the cylinder 607 can be extended. After the cylinder 607 extends, the stop block 504 will also extend, thereby restricting the workpiece carrier from moving forward.
[0031] At this point, the cylinder 607 is extended again. After the cylinder 607 extends again, it will drive the first push rod 604 and the second push rod 605 to continue moving upward. When the first push rod 604 moves upward, the return spring 602 will be compressed; when the second push rod 605 moves upward, it will drive the lifting seat 507 to move upward, thereby pushing the workpiece carrier away from the double-line conveyor belt 3.
[0032] like Figure 5 and Figure 6 As shown, an extension mechanism 7 is installed on the lifting seat 507. The extension mechanism 7 includes a limiting slide groove 701 opened on the lifting seat 507 and a threaded tube 702 fixedly installed in the lifting seat 507. An extension plate 703 is slidably installed in the limiting slide groove 701. A connecting leg 704 is fixedly installed at the end of the extension plate 703. A threaded rod 706 is threadedly installed in the threaded tube 702. A knob 705 is fixedly installed at the end of the threaded rod 706, and the threaded rod 706 is rotatably installed on the connecting leg 704.
[0033] When the operator manually rotates the threaded rod 706, the rotational motion of the threaded rod 706, through its threaded structure and the engagement with the connecting leg 704, causes the connecting leg 704 to produce a corresponding linear displacement, enabling it to move smoothly forward or backward. Specifically, when the connecting leg 704 moves forward under the drive of the threaded rod 706, this movement applies a pulling force to the connected extension plate 703. Under the action of the pulling force, the extension plate 703 gradually slides out along the limiting groove 701. As the extension plate 703 slides out, the surface area of the upper end of the lifting seat 507 also increases. The purpose of this design is to provide a larger support area so as to stably support larger or heavier workpiece carriers, thereby meeting the usage requirements under different working conditions and ensuring operational stability and safety.
[0034] Working Principle: During assembly, the workpiece carrier can be placed on the double-line conveyor belt 3. The double-line conveyor belt 3 can move the workpiece carrier to the assembly station. When the workpiece carrier moves to the assembly station, the cylinder 607 can be extended. After the cylinder 607 extends, the stop block 504 will also extend, thereby restricting the workpiece carrier from moving forward. At this time, the cylinder 607 can be extended again. After the cylinder 607 extends again, it will drive the first push rod 604 and the second push rod 605 to continue to move upward. When the first push rod 604 moves upward, the return spring 602 will be compressed. When the second push rod 605 moves upward, it will drive the lifting seat 507 to move upward, thereby pushing the workpiece carrier away from the double-line conveyor belt 3. After the workpiece carrier is pushed away from the double-line conveyor belt 3, the lead screw slide 502 can be activated. After the lead screw slide 502 is activated, it will drive the clamping plate 503 to approach the clamping block 506. Thus, the clamping action of the clamping plate 503 and the clamping block 506 will fix the workpiece carrier at the assembly station, facilitating the assembly operation. After assembly, the clamp 503 can be retracted to release the workpiece carrier. Then, the cylinder 607 can be retracted to reset the stop 504 and the lifting seat 507. After the stop 504 and the lifting seat 507 are reset, the double-line conveyor belt 3 can continue to drive the workpiece carrier to move, thereby removing the assembled workpiece.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
