Description

Technical Field

[0001] The utility model belongs to the technical field of copper wire winders, in particular to a copper wire winder for a loudspeaker drive unit. Background Art

[0002] Copper wires are used as transmission wires when producing speaker drive units for products such as smartphones, tablets, and laptops. Copper wires refer to wires made of copper as the base material and used as the inner core material for the production of wires and cables. Wires made of copper are generally of better quality. In terms of actual touch, copper wires are softer than wires made of general materials and can withstand larger currents.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: in the process of producing copper wires, one of the steps is to wind the copper wires on a winder to reduce the space occupied by the copper wires and make them easier to transport and store. However, the current winders usually just wind the copper wires on them in a relatively random manner, resulting in the copper wires being arranged in a messy manner on the winder, which is not aesthetically pleasing.

[0004] Therefore, we propose a copper wire winder for a loudspeaker drive unit to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a copper wire winder for a speaker drive unit, so that the copper wire can be covered on the winding drum more regularly, avoiding the unsightly appearance caused by the messy distribution of the copper wire, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A copper wire winder for a loudspeaker drive unit comprises a support and a winding mechanism located on the support, the winding mechanism comprising a servo motor horizontally mounted on a side wall of the support, an inner support shaft rotatably connected to both sides of the support, and a winding drum welded between the two inner support shafts, wherein the output shaft of the servo motor is coaxially connected to one of the inner support shafts;

[0008] An extension frame is horizontally welded on one side wall of the support, wherein a knob is rotatably connected to the extension frame, a penetration groove penetrating through the two side walls thereof is formed on the extension frame, and a slide groove is formed on the top wall and the bottom wall of the penetration groove toward the inside of the extension frame, respectively, the two slide grooves are symmetrical to the upper and lower sides of the penetration groove, and a screw rod and a limit rod are respectively arranged in the two slide grooves;

[0009] The screw rod is coaxially connected to the knob, and both sides of the limit rod are fixedly connected to the extension frame. A limit block is slidably provided in the penetration groove, wherein one side of the limit block is threadedly sleeved on the screw rod, and the other side thereof is slidably sleeved on the limit rod. The limit block is provided with threading holes that penetrate through its two side walls and are used for the copper wire to pass through.

[0010] As a preferred embodiment, the two inner support shafts are both arranged horizontally and symmetrically on both sides of the winding drum, and the inner support shafts and the winding drum are designed to be coaxial; so that the two inner support shafts can rotate inside the winding drum and drive the winding drum to rotate coaxially.

[0011] As a preferred embodiment, a groove is formed at the bottom of one side wall of the extension frame, and the knob is installed in the groove; so that the knob can be hidden in the groove, thereby protecting the knob to a certain extent.

[0012] As a preferred embodiment, the screw rod and the limiting rod are both arranged horizontally, and the screw rod is located directly below the limiting rod, and both sides of the screw rod are rotatably connected to the extension frame; so that the screw rod can operate stably under the drive of the knob.

[0013] As a preferred embodiment, a positioning frame is fixedly bonded to a side of the support facing away from the extension frame, wherein two springs are symmetrically connected to the inner wall of the positioning frame; the extension frame and the positioning frame are both U-shaped.

[0014] As a preferred embodiment, a pressure plate is connected to the two springs, wherein the side of the pressure plate facing away from the two springs is an arc surface; thereby making it easy for the pressure plate to contact the copper wire after winding, to limit the copper wire and prevent it from falling off the winding drum.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] The copper wire winder of the speaker drive unit can continuously wind the copper wire by driving the servo motor to drive the winding drum to operate. According to actual needs, the limit block is slowly moved from one side of the winding drum to the other side, so that the copper wire can be covered on the winding drum more regularly, avoiding the unsightly appearance caused by the messy distribution of the copper wire.

[0017] In the copper wire winder of the speaker drive unit, during the winding process, as the servo motor runs, the space on the outer wall of the winding drum near the servo motor is gradually used up. At this time, the knob can be gradually turned to drive the screw to run, driving the limit block to move horizontally along with the limit rod and gradually move away from the servo motor, so that through the threading hole on the limit block, the position of the copper wire that subsequently enters the inner side of the winding drum is gradually moved horizontally on the winding drum, and finally the copper wire is evenly distributed everywhere on the outer wall of the winding drum.
