Description

Technical Field

[0001] The utility model relates to voice coil production equipment, in particular to a voice coil feeding mechanism of a voice coil winding machine. Background Art

[0002] The voice coil is the core component of the speaker. As electronic devices become more and more popular, the demand for voice coils is also increasing. The production of voice coils includes processes such as frame forming, winding, and pasting. Due to the large demand for production, the industry has gradually begun to adopt automated assembly line operations to carry out the various processes of voice coil production.

[0003] For the voice coil winding process, the voice coil needs to be fixed before the coil is wound. Usually, the cylindrical voice coil frame is mounted on the cylindrical sound gauge for processing. The voice coil frame is basically made of film. If the force is too strong when clamping the sound gauge, the film will be deformed, and if the force is not enough, it cannot be assembled in place. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a voice coil feeding mechanism of a voice coil winding machine, which specifically adopts the following technical solutions.

[0005] The voice coil feeding mechanism of the voice coil winding machine includes:

[0006] The sound gauge is cylindrical; a voice coil frame to be wound is sleeved on the sound gauge;

[0007] A feeding sleeve, a sound gauge is coaxially installed into one end of the feeding sleeve;

[0008] The pneumatic collet is coaxially matched with the end of the feeding sleeve that is loaded into the gauge;

[0009] The advance and retreat unit is used to drive the feeding sleeve to move axially so that the end of the feeding sleeve that is loaded into the gauge can be butted with the pneumatic collet;

[0010] A positioning unit, used for driving the tone gauge to be disengaged from one end of the feeding sleeve that is butt-jointed with the pneumatic collet;

[0011] Push-flat unit for knocking the gauge coming out of the loading sleeve towards the pneumatic collet.

[0012] Furthermore, the advance and retreat unit includes a first slide rail, a first slide table slidably matched with the first slide rail, a first transmission screw matched with the first slide table to form a screw transmission, and a first servo motor driving the first transmission screw to rotate. The loading sleeve, positioning unit, and flattening unit are all arranged on the first slide table.

[0013] Furthermore, one end of the feeding sleeve facing the winding gauge has a guide groove opened along the diameter, and the positioning unit has a cross bar running through the guide groove and a translation device driving the feeding sleeve to move axially relative to the cross bar.

[0014] Furthermore, the translation device includes a second slide rail, a second slide table slidably matched with the second slide rail, a second transmission screw matched with the second slide table to form a screw transmission, and a second servo motor driving the second transmission screw to rotate, and the loading sleeve is arranged on the second slide table.

[0015] Furthermore, the flattening unit includes a push rod coaxially matched with the loading sleeve, and the push rod is located at one end of the loading sleeve away from the pneumatic collet; the positioning unit also includes a cylinder driving the push rod to move axially, and the push rod reciprocates through the loading sleeve under the drive of the cylinder to knock the sound gauge that has escaped from the loading sleeve toward the pneumatic collet.

[0016] As an improvement of the above technical solution, it also includes a rotating disc and a divider driving the rotating disc. A plurality of equally spaced pneumatic collets are arranged around the top surface of the rotating disc. The axial direction of the pneumatic collet is arranged along the radial direction of the turntable. The divider drives the rotating disc to rotate in steps so that the pneumatic collet is sequentially matched with one end of the feeding sleeve to be loaded into the gauge.

[0017] Compared with the prior art, the beneficial effect of the utility model lies in: firstly, the feeding sleeve is driven to dock with the pneumatic collet through the advance and retreat unit, and then the positioning unit is used to drive the gauge to disengage from the feeding sleeve, so that the gauge is clamped in the pneumatic collet, and finally the flattening unit is used to knock the gauge toward the pneumatic collet, so that the position of the gauge clamped by the pneumatic collet is fine-tuned, which can not only ensure that the gauge is assembled in place, but also reduce the risk of deformation of the voice coil frame on the gauge.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a voice coil feeding mechanism of a voice coil winding machine in one embodiment, comprising:

[0022] The sound gauge 1 is cylindrical; a voice coil frame 2 to be wound is sleeved on the sound gauge 1;

[0023] The feeding sleeve 3 and the sound gauge 1 are coaxially installed into one end of the feeding sleeve 3;

[0024] The pneumatic collet 4 is coaxially matched with one end of the feeding sleeve 3 for loading the pitch gauge 1;

[0025] The advance and retreat unit 5 is used to drive the feeding sleeve 3 to move axially so that the end of the feeding sleeve 3 loaded into the gauge 1 is docked with the pneumatic collet 4;

[0026] The positioning unit 6 is used to drive the gauge 1 to be disengaged from one end of the feeding sleeve 3 that is butt-jointed with the pneumatic collet 4;

[0027] The push-flat unit 7 is used to knock the pitch gauge 1 that has escaped from the feeding sleeve 3 toward the pneumatic collet chuck 4.

[0028] In the above embodiment, the feeding sleeve 3 is first driven to dock with the pneumatic collet 4 by the advance and retreat unit 5, and then the positioning unit 6 is used to drive the gauge 1 to disengage from the feeding sleeve 3, so that the gauge 1 is clamped in the pneumatic collet 4, and finally the pushing unit 7 is used to knock the gauge 1 toward the pneumatic collet 4, so that the position of the gauge 1 clamped by the pneumatic collet 4 is fine-tuned, which can not only ensure that the gauge 1 is assembled in place, but also reduce the risk of deformation of the voice coil frame 2 on the gauge 1.

[0029] It is worth mentioning that the intensity of the knocking action of the pushing unit 7 on the tone gauge 1 can be debugged and set according to the production situation to ensure that the knocking action can just adjust the position of the tone gauge 1 without damaging the voice coil frame 2 on the tone gauge 1.

[0030] In the above embodiment, further, the advance and retreat unit 5 includes a first slide rail 51, a first slide 52 slidably fitted on the first slide rail 51, a first transmission screw 53 that forms a screw transmission with the first slide 52, and a first servo motor 54 that drives the first transmission screw 53 to rotate. The loading sleeve 3, the positioning unit 6, and the flattening unit 7 are all arranged on the first slide 52.

[0031] In the above embodiment, further, the end of the feeding sleeve 3 facing the winding gauge 1 has a guide groove 31 opened along the diameter, and the positioning unit 6 has a crossbar 61 that crosses the guide groove 31 and a translation device 62 that drives the feeding sleeve 3 to move axially relative to the crossbar 61. It is not difficult to understand that the positioning unit 6 drives the gauge 1 to escape from the feeding sleeve 3 in the following manner:

[0032] When the translation device 62 drives the loading sleeve 3 to move axially away from the pneumatic collet 4, since the cross bar 61 runs across the guide groove 31, the cross bar 61 will block the gauge 1 in the loading sleeve 3, thereby causing the gauge 1 to escape from the loading sleeve 3; at the same time, in the process of driving the gauge 1 to escape from the loading sleeve 3 through the positioning unit 6, since the gauge 1 and the loading sleeve 3 are in relative motion, the advance and retreat unit 5 and the positioning unit 6 can cooperate with each other, so that the loading sleeve 3 and the pneumatic collet 4 remain connected while the gauge 1 escapes from the loading sleeve 3 and enters the pneumatic collet 4.

[0033] In the above embodiment, further, the translation device 62 includes a second slide rail 63, a second slide table 64 slidably fitted on the second slide rail 63, a second transmission screw 65 that forms a screw transmission with the second slide table 64, and a second servo motor 66 that drives the second transmission screw 65 to rotate, and the loading sleeve 3 is arranged on the second slide table 64.

[0034] In the above embodiment, further, the flattening unit 7 includes a push rod 71 coaxially matched with the loading sleeve 3, and the push rod 71 is located at one end of the loading sleeve 3 away from the pneumatic collet 4; the positioning unit 6 also includes a cylinder 72 for driving the push rod 71 axially to move, and the push rod 71 reciprocates through the loading sleeve 3 under the drive of the cylinder 72 to knock the gauge 1 that has escaped from the loading sleeve 3 toward the pneumatic collet 4.

[0035] In another preferred embodiment, the voice coil feeding mechanism of the voice coil winding machine of the utility model also includes a rotating disk 8 and a divider 81 for driving the rotating disk 8. A plurality of equally spaced pneumatic collets 4 are arranged around the top surface of the rotating disk 8. The axial direction of the pneumatic collet 4 is arranged along the radial direction of the turntable. The divider 81 drives the rotating disk 8 to rotate in steps so that the pneumatic collet 4 sequentially cooperates with one end of the feeding sleeve 3 to be loaded into the gauge 1, thereby realizing high-speed continuous production.

[0036] For those skilled in the art, the protection scope of the present invention is not limited to the details of the above-mentioned exemplary embodiments. Without departing from the spirit or basic characteristics of the present invention, the equivalent meanings and all changes in the protection scope made by those skilled in the art based on the requirements of the present invention should be included in the present invention.
