[0002] A voice coil is a coil through which current passes in a loudspeaker and is an important part of the mechanical wave system of an electro-dynamic loudspeaker. It can also be said to be the heart of the loudspeaker. The voice coil is mainly composed of a skeleton and a coil. During its production process, glue needs to be brushed on the surface of the skeleton. In the existing production process, generally, the voice coil is sleeved on a cylindrical fixture 4 as shown in the attachment Figure 1 to position the voice coil and facilitate glue brushing on the surface of the voice coil skeleton. Currently, the glue brushing operation of the voice coil is basically carried out manually. It is difficult to control the amount of glue brushed, resulting in an increase in the amount of glue used, an increase in material costs, a large amount of manpower input, an increase in labor costs, and low production efficiency. Summary of the Invention

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure.

[0017] Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0018] Refer to Figures 1-5 。

[0019] The present utility model provides a voice coil automatic glue brushing machine, which includes a machine table. On the machine table, there are arranged a loading and unloading station 1, a spindle station 2, and a glue brushing station 3. The loading and unloading station 1 includes an X-axis slide plate 10 slidably connected to the machine table in the X-axis direction, a loading mechanism 11 and an unloading mechanism 12 symmetrically arranged on both sides of the X-axis slide plate 10, and an X-axis driving cylinder 13 arranged on the machine table and drivingly connected to the X-axis slide plate 10. The spindle station 2 includes a Y-axis linear driving mechanism 20 and a spindle mechanism 21 arranged on the machine table. The spindle mechanism 21 includes a rotating base 210 drivingly connected to the Y-axis linear driving mechanism 20, a spindle 211 rotatably connected to the rotating base 210, and a spindle driving motor 212 arranged on one side of the rotating base 210 and drivingly connected to the spindle 211. The glue brushing station 3 includes a bracket 30 arranged on the machine table, a three-dimensional fine adjustment platform 31 arranged on the bracket 30, a glue brushing driving cylinder 32 loaded on the three-dimensional fine adjustment platform 31, and a glue brushing syringe 33 drivingly connected to the glue brushing driving cylinder 32.

[0020] Its working principle is as follows: a conveyor belt running in the X-axis direction can be arranged at the lower side of the machine table. The cylindrical jig 4 with a voice coil sleeved thereon is placed on the conveyor belt and conveyed towards the feeding mechanism 11. The position of the glue-brushing syringe 33 can be adjusted by the three-dimensional fine-tuning platform 31 according to the glue-brushing position of the voice coil. When the X-axis driving cylinder 13 works, it can drive the feeding mechanism 11 and the discharging mechanism 12 to move in the X-axis direction. When the voice coil to be glue-brushed is conveyed to the feeding mechanism 11, the feeding mechanism 11 picks up the cylindrical jig 4 with the voice coil sleeved thereon from the conveyor belt and assembles it onto the main shaft 211. The glue-brushing driving cylinder 32 drives the needle head of the glue-brushing syringe 33 to contact the glue-brushing position of the voice coil, and the main shaft driving motor 212 drives the main shaft 211 to rotate, thereby driving the voice coil to rotate 360°, so as to perform the glue-brushing operation on the voice coil skeleton. After the glue-brushing is completed, the discharging mechanism 12 takes out the cylindrical jig 4 from the main shaft 211 and places it on the conveyor belt. The automation of feeding, glue-brushing, and discharging can be realized, ensuring the stability of the glue amount, saving labor, reducing production costs, and improving production efficiency.

[0021] Based on the above embodiments, both the feeding mechanism 11 and the discharging mechanism 12 include mounting vertical plates 110 fixedly connected to one end of the X-axis sliding plate 10, rotary cylinders 111 arranged on the mounting vertical plates 110, material-taking driving cylinders 112 drivingly connected to the rotary cylinders 111, and pneumatic grippers 113 drivingly connected to the material-taking driving cylinders 112. Clamping arms 114 are installed on both clamping jaws of the pneumatic gripper 113. When the rotary cylinder 111 works, it can drive the pneumatic gripper 113 to swing longitudinally. When the material-taking driving cylinder 112 works, it can drive the pneumatic gripper 113 to perform material-taking and discharging actions. When the pneumatic gripper 113 clamps the cylindrical jig 4, the two clamping arms 114 extend into the inner hole of the cylindrical jig 4 and open, thereby grasping the cylindrical jig 4.

[0022] Based on the above embodiments, the main shaft 211 includes a connecting cylinder 211a and a head sleeve 211b. The head sleeve 211b includes a cylindrical portion 211c fixedly connected to one end of the connecting cylinder 211a and arc-shaped elastic pieces 211d evenly distributed at one end of the cylindrical portion 211c. A shaft hole is penetrated through the rotary seat 210, and the connecting cylinder 211a and the shaft hole are connected by a bearing. The main shaft driving motor 212 and the connecting cylinder 211a are connected by a synchronous belt drive. When the feeding mechanism 11 assembles the cylindrical jig 4 onto the main shaft 211, the cylindrical jig 4 is assembled between the arc-shaped elastic pieces 211d, and the arc-shaped elastic pieces 211d will open and clamp the cylindrical jig 4. By driving the connecting cylinder 211a to rotate through the main shaft driving motor 212, the cylindrical jig 4 and the voice coil can be driven to rotate.

[0023] Based on the above embodiments, the spindle station 2 further includes a pushing mechanism 213. The pushing mechanism 213 includes a connecting frame 213a fixedly connected to one side of the rotating seat 210, a pushing cylinder 213b disposed on the connecting frame 213a, and a push rod 213c drivingly connected to the pushing cylinder 213b and movably disposed inside the connecting cylinder 211a. When the blanking mechanism 12 removes the cylindrical jig 4 from the spindle 211, the two clamping arms 114 of the pneumatic gripper 113 are closed and located at the front side of the cylindrical jig 4. The push rod 213c is driven by the pushing cylinder 213b to move forward to push the cylindrical jig 4 out of the head cover 211b. The cylindrical jig 4 will hang on the two clamping arms 114, and the blanking mechanism 12 can then clamp and transfer the cylindrical jig 4 to the conveyor belt.

[0024] Based on the above embodiments, the Y-axis linear driving mechanism 20 includes a Y-axis sliding seat 200 disposed on the machine table, a Y-axis sliding block 201 slidably connected to the Y-axis sliding seat 200, and a driving motor 202 disposed on the machine table and connected to the Y-axis sliding block 201 through a lead screw. The rotating seat 210 is fixedly connected to the top of the Y-axis sliding block 201. When the driving motor 202 operates, the Y-axis sliding block 201 will move along the Y-axis sliding seat 200, thereby driving the spindle mechanism 21 to move back and forth.

[0025] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
