Description

Technical Field

[0001] This utility model relates to the field of microphone manufacturing technology, specifically to a microphone body pin soldering mechanism. Background Technology

[0002] A microphone is a transducer that converts sound waves into electrical signals. It is widely used in various audio devices, such as tape recorders, telephones, computers, and hearing aids. The pins of a microphone need to be soldered to ensure a good electrical connection between them and circuit boards or other electronic components.

[0003] When existing soldering mechanisms solder the pins, the solder adhering to the pins tends to accumulate at the bottom of the pins. This excessive concentration of solder at the bottom of the pins may change the actual length of the pins, causing the microphone to shift position when installed on the circuit board or other components, affecting assembly accuracy and hindering subsequent installation. Utility Model Content

[0004] The purpose of this invention is to provide a soldering mechanism for the microphone body pins, which can make the solder liquid more evenly distributed on the pin surface during the soldering of the microphone pins, avoid the situation of solder accumulating at the bottom of the pins, and make the subsequent installation of the microphone pins more accurate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microphone body pin tinning mechanism, including a worktable, a tinning mechanism on the surface of the worktable, and a movable mechanism and a pushing mechanism on one side of the tinning mechanism;

[0006] The movable mechanism includes a U-shaped plate, a geared motor fixed to the surface of the U-shaped plate, an output shaft of the geared motor passing through the U-shaped plate and fixed to a cross rod, one end of the cross rod being rotatably connected to the inner wall of the U-shaped plate, a reciprocating lead screw being rotatably connected to the inner wall of the U-shaped plate, a movable sleeve being slidably connected to the surface of the cross rod, two ball bearings being fixed to the surface of the movable sleeve, a movable frame being fixed to the surface of the ball bearings, two guide rods being fixed to the surface of the U-shaped plate, the guide rods slidingly passing through the movable frame, a sliding sleeve being threadedly connected to the surface of the reciprocating lead screw, the sliding sleeve being fixedly connected to the surface of the movable frame, a plurality of first bevel gears being fixed to the surface of the movable sleeve, second bevel gears meshing with the surfaces of the first bevel gears, a drive rod being fixed to the surface of the second bevel gears, the drive rod passing through the movable frame, a clamping mechanism being installed on the surface of the drive rod, and a drive structure being provided on one side of the U-shaped plate.

[0007] As a preferred embodiment of the tinning mechanism for the pickup body pins of this utility model, the tinning mechanism includes a tin furnace, which is fixed to the top of the workbench. A tin melting pump is connected to the surface of the tin furnace. A bracket is fixed to the top of the tin furnace. A distribution pipe is fixed to the surface of the bracket. Multiple discharge heads are connected to the surface of the distribution pipe. A ceramic tube is connected to the liquid delivery end of the tin melting pump. One end of the ceramic tube is connected to the distribution pipe.

[0008] As a preferred embodiment of the microphone body pin soldering mechanism of this utility model, the pushing mechanism includes a mounting frame, which is fixed to the top of the workbench. A vertical plate is fixed to the top of the mounting frame, and a cylinder is fixed to the surface of the vertical plate. One end of the cylinder passes through the vertical plate and is fixed to a connecting plate. The surface of the connecting plate is fixedly connected to the surface of the U-shaped plate. Multiple guide rods slide through the surface of the vertical plate, and one end of each guide rod is fixedly connected to the surface of the connecting plate.

[0009] As a preferred embodiment of the microphone body pin soldering mechanism of this utility model, the top of the mounting bracket has two slide rails fixedly connected, and a slider is slidably connected to the surface of the slide rails. The top of the slider is fixedly connected to the bottom of the connecting plate.

[0010] As a preferred embodiment of the microphone body pin soldering mechanism of this utility model, the clamping mechanism includes a combination plate, a connecting shell fixed to the surface of the combination plate, the surface of the connecting shell being fixedly connected to the surface of the drive rod, a bidirectional lead screw rotatably connected to the surface of the combination plate, one end of the bidirectional lead screw passing through the combination plate and fixed with a handwheel, a sliding groove being formed on the surface of the combination plate, two movable sleeves being threadedly connected to the surface of the bidirectional lead screw, a clamping plate being fixed to the surface of the movable sleeve, and the surface of the clamping plate being slidably connected to the surface of the sliding groove.

[0011] As a preferred embodiment of the microphone body pin soldering mechanism of this utility model, the driving structure on one side of the U-shaped plate is a sprocket, and there are multiple sprockets. The sprockets are respectively fixed to the surface of the cross rod and the reciprocating lead screw, and the sprockets on both sides are connected by chain drive.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, when the geared motor starts, it drives the crossbar to rotate. The crossbar drives the movable sleeve to rotate as well. This allows multiple first bevel gears on the surface of the movable sleeve to drive second bevel gears to rotate synchronously. Consequently, multiple drive rods can drive the clamping mechanism to rotate, allowing the microphone installed inside the clamping mechanism to rotate as well. The design of the ball bearing and guide rod ensures that the movable sleeve cannot drive the movable frame to rotate. The drive structure allows the reciprocating screw to rotate with the crossbar. When the reciprocating screw rotates, the sliding sleeve on its surface will be affected by the thread and begin to reciprocate. The sliding sleeve can then drive the movable frame to move along with the guide rod, allowing the movable sleeve to move continuously on the surface of the crossbar. This achieves the effect of reciprocating movement during the microphone rotation, ensuring that the microphone pin surface can evenly contact the molten solder flowing from the soldering mechanism. This soldering method can prevent molten solder from accumulating at the bottom of the pins, thereby improving the accuracy of pin installation after soldering. Attached Figure Description

Detailed Implementation

[0020] Please see Figures 1-5 A microphone body pin tinning mechanism includes a worktable 1, a tinning mechanism 2 on the surface of the worktable 1, and a movable mechanism 3 and a pushing mechanism 4 on one side of the tinning mechanism 2.

[0021] The moving mechanism 3 includes a U-shaped plate 301, a geared motor 302 fixed to the surface of the U-shaped plate 301, the output shaft of the geared motor 302 passing through the U-shaped plate 301 and fixed to a cross rod 303, one end of the cross rod 303 being rotatably connected to the inner wall of the U-shaped plate 301, a reciprocating lead screw 307 being rotatably connected to the inner wall of the U-shaped plate 301, a movable sleeve 304 being slidably connected to the surface of the cross rod 303, the inner wall shape of the movable sleeve 304 being adapted to the cross rod 303, two ball bearings 305 being fixed to the surface of the movable sleeve 304, a movable frame 306 being fixed to the surface of the ball bearings 305, and two guide rods being fixed to the surface of the U-shaped plate 301. 312, the guide rod 312 slides through the movable frame 306, the reciprocating screw 307 is threadedly connected to the sliding sleeve 308, the surface of the sliding sleeve 308 is fixedly connected to the surface of the movable frame 306, the movable sleeve 304 is fixedly fixed with multiple first bevel gears 309, the surface of the first bevel gears 309 is meshed with second bevel gears 310, the surface of the second bevel gears 310 is fixed with a drive rod 311, the surface of the drive rod 311 passes through the movable frame 306, the drive rod 311 is rotatably connected to the surface of the movable frame 306 at the point of penetration, the surface of the drive rod 311 is mounted with a clamping mechanism 5, and a drive structure is provided on one side of the U-shaped plate 301;

[0022] When the geared motor 302 starts, it drives the cross bar 303 to rotate. The cross bar 303 drives the movable sleeve 304 to rotate as well. This allows the multiple first bevel gears 309 on the surface of the movable sleeve 304 to drive the second bevel gears 310 to rotate synchronously. This allows the multiple drive rods 311 to drive the clamping mechanism 5 to rotate simultaneously, and also allows the microphone installed inside the clamping mechanism 5 to rotate. The design of the ball bearing 305 and the guide rod 312 ensures that the movable sleeve 304 cannot drive the movable frame 306 to rotate. The drive structure setting makes the reciprocating screw... 307 can rotate together with the cross rod 303. When the reciprocating screw 307 rotates, the sliding sleeve 308 on its surface will start to reciprocate due to the influence of the thread. The sliding sleeve 308 can also drive the movable frame 306 to move together with the guide rod 312, so that the movable sleeve 304 can move continuously on the surface of the cross rod 303. This achieves the effect of reciprocating movement during the rotation of the microphone, so that the surface of the microphone pin can be evenly contacted with the solder flowing out of the soldering mechanism 2. This soldering method can avoid the solder molten metal from accumulating at the bottom of the pin, thereby improving the accuracy of the pin installation after soldering.

[0023] Furthermore, the tin coating mechanism 2 includes a tin furnace 201, which is fixed to the top of the workbench 1. A tin melting pump 202 is connected to the surface of the tin furnace 201. A bracket 203 is fixed to the top of the tin furnace 201. A diversion pipe 204 is fixed to the surface of the bracket 203. Multiple discharge heads 205 are connected to the surface of the diversion pipe 204. A ceramic tube 206 is connected to the liquid delivery end of the tin melting pump 202. One end of the ceramic tube 206 is connected to the diversion pipe 204.

[0024] The tin furnace 201 is used to store molten tin. When the molten tin pump 202 is working, it can draw the molten tin from the tin furnace 201 and transport it through the ceramic tube 206 to the inside of the distribution tube 204. Then, it flows out downward from the outlet head 205 on the surface of the distribution tube 204, so that the molten tin can be sprayed onto the pin surface of the microphone, realizing the tinning operation of the microphone pin.

[0025] Furthermore, the pushing mechanism 4 includes a mounting frame 401, which is fixed to the top of the workbench 1. A vertical plate 402 is fixed to the top of the mounting frame 401. A cylinder 403 is fixed to the surface of the vertical plate 402. One end of the cylinder 403 passes through the vertical plate 402 and is fixed to a connecting plate 404. The surface of the connecting plate 404 is fixedly connected to the surface of the U-shaped plate 301. Multiple guide rods 405 slide through the surface of the vertical plate 402. One end of each guide rod 405 is fixedly connected to the surface of the connecting plate 404.

[0026] The guide rod 405 can move together with the connecting plate 404, and the guide rod 405 can also move on the surface of the upright plate 402. This allows the connecting plate 404 to move in a guiding manner. When the cylinder 403 is started, it can drive the connecting plate 404 to move, and the connecting plate 404 can drive the U-shaped plate 301 to move together, so that the U-shaped plate 301 can be moved away from the solder pot 201. This makes it safer for operators to install and remove the microphone.

[0027] Furthermore, two slide rails 406 are fixed to the top of the mounting bracket 401, and sliders 407 are slidably connected to the surface of the slide rails 406. The top of the sliders 407 is fixedly connected to the bottom of the connecting plate 404.

[0028] The connecting plate 404 can drive the slider 407 to slide on the surface of the slide rail 406, which enables the connecting plate 404 to achieve a linear guiding effect and also allows the weight of the connecting plate 404 to be distributed to the slide rail 406 through the slider 407, thereby further improving the stability of the connecting plate 404.

[0029] Furthermore, the clamping mechanism 5 includes a combination plate 501, a connecting shell 502 fixed on the surface of the combination plate 501, the surface of the connecting shell 502 being fixedly connected to the surface of the drive rod 311, a bidirectional lead screw 503 rotatably connected to the surface of the combination plate 501, one end of the bidirectional lead screw 503 passing through the combination plate 501 and fixed with a handwheel 504, a sliding groove 506 being opened on the surface of the combination plate 501, two movable sleeves 505 being threadedly connected to the surface of the bidirectional lead screw 503, a clamping plate 507 being fixed on the surface of the movable sleeve 505, and the surface of the clamping plate 507 being slidably connected to the surface of the sliding groove 506;

[0030] After the microphone is placed between the two clamping plates 507 with the pins directly below the discharge head 205, rotating the handwheel 504 can rotate the bidirectional lead screw 503, thereby causing the moving sleeve 505 to move in opposite directions due to the thread, allowing the clamping plate 507 to slide on the surface of the slide groove 506. This allows the clamping plate 507 to hold and fix the microphone, ensuring that the clamping plate 507 can drive the microphone to rotate normally.

[0031] Furthermore, the driving structure on one side of the U-shaped plate 301 is a sprocket 313. There are multiple sprockets 313, which are fixed to the surfaces of the cross rod 303 and the reciprocating screw 307 respectively. The two sprockets 313 are connected by chain drive.

[0032] When the geared motor 302 drives the cross rod 303 to rotate, the cross rod 303 can drive the reciprocating screw 307 to rotate synchronously through the cooperation of its own surface sprocket 313 and the surface sprocket 313 of the reciprocating screw 307, so that the cross rod 303 and the reciprocating screw 307 can rotate together.

[0033] Working principle: After the microphone is placed between the two clamping plates 507 with the pins directly below the discharge head 205, rotating the handwheel 504 can clamp and fix the microphone between the two clamping plates 507. Then, the geared motor 302 starts, causing the cross rod 303 and the reciprocating screw 307 to rotate simultaneously. The cross rod 303 can drive multiple drive rods 311 and the combination plate 501 to rotate together through the cooperation of multiple first bevel gears 309 and second bevel gears 310. This allows the microphone body clamped by the clamping plates 507 to rotate as well. When the reciprocating screw 307 rotates, the sliding sleeve 308 can drive the movable frame 306 to reciprocate, so that the movable sleeve 304 can move continuously on the surface of the cross rod 303. This achieves the effect of reciprocating movement during the rotation of the microphone, so that the surface of the microphone pins can be evenly contacted with the molten solder flowing from the discharge head 205. This soldering method can prevent molten solder from accumulating at the bottom of the pins, thereby improving the accuracy of the pin installation after soldering.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
