Description

Technical Field

[0001] The invention relates to the technical field of glue potting machines, and more specifically to a glue potting machine for speaker production. Background Art

[0002] A speaker is a device that can convert audio signals (usually electronic signals) into sound. It is an indispensable component of the sound system and is responsible for converting audio signals into sound waves so that we can hear music, voice or other sounds.

[0003] The coil and diaphragm of the speaker are the key components of the speaker. In order to ensure a stable connection between the voice coil and the diaphragm, glue needs to be applied between them for bonding. Glue injection requires the use of a glue filling machine, whose main function is to ensure the stability and sealing of the voice coil and diaphragm in the speaker. The glue filling machine is an automated machine specially used to control fluids and drip, apply, and pour liquids on the surface or inside of products. It is mainly composed of a glue filling mechanism, a mechanical mechanism, a pressurizing mechanism, and a cleaning mechanism.

[0004] The shortcomings of existing glue filling machines for speaker production: First, the glue of the glue pouring machine is stored in a glue tank. Every time the glue tank is filled with glue, a gap is left between the glue tank and the feed port because the glue is difficult to fill. This causes bubbles to appear when the pouring machine is applying glue to the voice coil and diaphragm in the speaker, resulting in loose bonding, which directly affects the sound quality and reliability of the speaker, thereby reducing product quality.

[0005] Second, when gluing the surface of the inner voice coil and the diaphragm, the glue injection port needs to be aligned with the inner voice coil and then the inner voice coil is manually rotated. However, the inner voice coil is in the shape of a horn, and it is difficult for the staff to apply the glue into a complete closed circle on one side when applying the glue. As a result, the gaps need to be filled manually after gluing, which delays work efficiency and is not very beautiful.

[0006] Third: During the gluing process, due to the different sizes of the speakers, the size of the inner voice coil in the speaker will also change accordingly, but the size of the glue head in the glue filling machine is fixed, which requires the staff to apply glue multiple times according to the size of the inner voice coil. Summary of the invention

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a glue potting machine for speaker production to solve the problems existing in the above-mentioned background technology.

[0008] The present invention provides the following technical solution: a glue filling machine for speaker production, comprising a housing and a glue tank fixedly mounted on the top of the housing, a protective shell mounted on the top of the glue tank, a transmission assembly for providing power to the device mounted inside the protective shell, the transmission assembly comprising an eccentric block, a stirring assembly for stirring glue connected to the bottom of the eccentric block, a glue coating assembly for coating glue on an inner voice coil placed in the middle of the housing, and a rotating table assembly placed at the bottom of the inner voice coil; The transmission assembly includes a motor, a first conical tooth, a second conical tooth, a first transmission rod, a first transmission wheel, a transmission belt, a second transmission wheel, a second transmission rod, a first gear, a connecting block, an eccentric block, a first limit fixing ring, and a second limit fixing ring, wherein the first limit fixing ring and the second limit fixing ring are fixed on a protective shell, a connecting block is provided on the top of the first limit fixing ring, the centers of the connecting block, the first limit fixing ring and the second limit fixing ring are on the same axis, an eccentric block is connected to one side of the bottom of the connecting block, the top of the connecting block is connected to the first transmission rod, and the bottom end of the first transmission rod is connected to the first transmission wheel, the first transmission wheel and the second transmission wheel are powered by the transmission belt, and the first conical tooth is connected to the top of the first transmission rod in order to rotate the first gear at the bottom by setting the second transmission rod; Furthermore, a second conical tooth is connected to one side of the first conical tooth, and the transmission mechanism has a power source by providing power to the first conical tooth through a motor, and chamfers are provided at the bottom of the first limit fixing ring and the top of the second limit fixing ring.

[0009] Furthermore, the protective shell is installed on the top of the glue tank to provide support and protection for the transmission assembly.

[0010] Furthermore, the stirring assembly includes a connecting rod, a first arc surface block, a second gear, a second arc surface block, a first stirrer, a stirring rod, and a second stirrer, and the connecting rod is connected to the eccentric block.

[0011] Furthermore, the glue coating assembly includes a glue applicator, a splint, a round block, an adjuster, a round sleeve, a polyester fiber board, bristles, and a glue outlet pipe. The glue flows into the proportional adjuster through the lower glue pipe. When the glue flows to the glue applicator through the glue outlet pipe, the adjuster is rotated according to the size of the inner voice coil. The position of the adjuster can be limited and fixed by the setting of the round sleeve.

[0012] Furthermore, when the adjuster is rotated, one end of the adjuster abuts against the round block and pushes the clamping plate to move, the inside of the clamping plate is movably connected with bristles, and the top of the bristles is fixedly connected with a polyester fiberboard.

[0013] Furthermore, the rotating table assembly includes a push rod, a block, a bar tooth, a third gear, a support rod, a rotating shaft, a placement block, a spring, a clamping block, a cushion, and an inner voice coil. The inner voice coil located on the top of the placement block is pushed to one side, and the spring fixedly connected to the inner voice coil begins to shrink, and then the inner voice coil is placed in a splint, and a cushion is fixedly connected to the inner side of the splint.

[0014] Furthermore, a bar tooth is fixedly connected to one side of the block, and the movement of the bar tooth causes the third gear to start rotating. A support rod is fixedly connected to the middle of the third gear, and a rotating shaft is fixedly connected to the bottom of the support rod.

[0015] Technical effects and advantages of the present invention: 1. The present invention starts the motor to make the first connecting block and the second connecting block drive the connecting rod to move inside the glue tank, and the first limit fixing ring of the first arc surface block is set to make the connecting rod rotate coaxially and in different directions, which can generate stronger shear force and stirring force. This stirring mode can reduce the generation of bubbles and improve the efficiency of bubble discharge. At the same time, during the stirring process, the crushed materials can be mixed more evenly to avoid glue stratification.

[0016] 2. The present invention makes the first gear start to rotate by setting the transmission belt, the first transmission wheel, the second transmission wheel and the second transmission rod, and the first gear and the second gear are adapted to each other, so that the connecting rod can rotate along its own central axis, so that the stirring rod installed on the connecting rod and the second stirrer can rotate along the central axis, ensuring that the glue is fully stirred in every corner of the glue tank, reducing the stirring dead angle, and allowing the air in the glue to be quickly discharged.

[0017] 3. The present invention rotates the regulator according to the size of the inner voice coil, and one end of the regulator abuts against the round block and squeezes the bristles through the clamping plate, so that the contact area between the bristles and the inner voice coil changes, which helps to reduce the repeated operation of the staff to apply glue multiple times according to the size of the inner voice coil, thereby improving the efficiency of the entire production line and also improving the accuracy and stability of gluing.

[0018] 4. The present invention pulls the push rod to make the block drive the bar teeth to move horizontally and drive the third gear to start rotating. When the third gear starts to rotate, the placement block starts to rotate. To ensure the convenient rotation of the placement block, a rotating shaft is installed at the bottom of the support rod to reduce friction and energy loss, thereby improving the efficiency of gear transmission. The inner voice coil rotates on the placement block as the support rod rotates, which is conducive to making the inner voice coil more uniform and smooth during the gluing process, reducing the complexity of the gluing operation and improving the accuracy and consistency of gluing.

The top of the first transmission rod 304 is connected to the first conical tooth 302, and one side of the first conical tooth 302 is connected to the second conical tooth 303. The first conical tooth 302 is powered by the motor 301, so that the transmission assembly 3 has a power source, and the bottom of the first limit fixing ring 307 and the top of the second limit fixing ring 308 are both chamfered.

[0032] Reference Figure 5The stirring assembly 4 includes a connecting rod 401, a first arc surface block 402, a second gear 403, a second arc surface block 404, a first stirrer 405, a stirring rod 406, and a second stirrer 407. The glue is injected into the glue tank 2 through the glue injection port 201, so that the connecting rod 401 is connected to the eccentric block 306. When the transmission assembly 3 starts to work, the eccentric block 306 drives the connecting rod 401 to start eccentric rotation. The first arc surface block 402 and the second arc surface block 404 are respectively The first limit fixing ring 307 and the second limit fixing ring 308 act in the same direction to make the connecting rod 401 rotate coaxially in the glue tank 2 in different directions. At this time, the second gear 403, under the action of the first gear 3045, makes the connecting rod 401 rotate along its own central axis. At this time, the stirring rod 406, the first stirrer 405 and the second stirrer 407 keep stirring in the glue tank 2, and the vacuum pump 204 installed on the top of the casing 1 is started to extract the air in the glue through the vacuum tube 203.

[0033] Reference Figure 6-7 The glue coating assembly 5 includes a glue coating device 501, a clamping plate 502, a round block 503, a regulator 504, a round sleeve 505, a polyester fiber board 506, a brush 507, and a glue outlet pipe 508. The glue flows into the proportional regulator 206 through the lower glue pipe 205, and then flows to the glue coating device 501 through the glue outlet pipe 508. The regulator 504 is rotated according to the size of the inner voice coil 608. The position of the regulator 504 can be limited and fixed by the arrangement of the round sleeve 505. When the regulator 504 is rotated, one end of the regulator 504 abuts against the round block 503 and pushes the clamping plate 502 to move. The clamping plate 502 The internal part is movably connected with bristles 507, and the top of the bristles 507 is fixedly connected with a polyester fiber board 506. After the movement of the splint 502, the polyester fiber board 506 and the bristles 507 begin to shrink, so that the contact area between the bristles 507 and the inner voice coil 608 changes. The polyester fiber board 506 has good elasticity and strength. When the bristles 507 need to be expanded, the splint 502 can be opened. When the bristles 507 need to be expanded, it is beneficial to reduce the repeated operation of the staff to apply glue multiple times according to the size of the inner voice coil 608, thereby improving the efficiency of the entire production line while also improving the accuracy and stability of gluing.

[0034] Reference Figure 8The rotating table assembly 6 includes a push rod 601, a block 602, a bar tooth 603, a third gear 604, a support rod 605, a rotating shaft 606, a placement block 607, a spring 6071, a clamping block 6072, and a cushion 6073. And the inner voice coil 608, the inner voice coil 608 arranged on the top of the placement block 607 is pushed to one side, and the spring 6071 fixedly connected to the inner voice coil 608 begins to shrink, and then the inner voice coil 608 is placed in the clamping block 6072, and the inner side of the clamping block 6072 is fixedly connected with a soft pad 6073. The setting of the soft pad 6073 can prevent the inner voice coil 608 from being damaged when the clamping block 6072 is expanded too much, and then the block 602 starts to move by pushing the push rod 601 in the moving groove 102 opened on the front side of the casing 1. One side of the block 602 is fixedly connected with a bar tooth 603. The movement of the bar tooth 603 causes the third gear 604 to start to rotate, and the third gear 604 starts to rotate. A support rod 605 is fixedly connected to the middle of the third gear 604, and a rotating shaft 606 is fixedly connected to the bottom of the support rod 605. The arrangement of the rotating shaft 606 and the support rod 605 can reduce friction and energy loss, thereby improving the transmission efficiency of the third gear 604. A placement block 607 is fixedly connected to the top of the support rod 605. The support rod 605 is driven to rotate by the third gear 604 and then the placement block 607 is driven to rotate by the support rod 605, so that the inner voice coil 608 starts to rotate in the glue coating port 101, which is beneficial to make the inner voice coil 608 more uniform and smooth during the glue coating process, reducing the complexity of the glue coating operation and improving the accuracy and consistency of the glue coating.

[0035] The working principle of the present invention is as follows: during use, the glue is injected into the glue tank 2. In order to eliminate the bubbles in the glue, the motor 301 is started to make the first conical teeth 302 and the second conical teeth 303 start to rotate. The rotation of the second conical teeth 303 drives the first transmission rod 304 to rotate. After the first transmission rod 304 rotates, the first transmission wheel 3041 rotates. After the first transmission wheel 3041 rotates, the transmission belt 3042 drives the second transmission wheel 3043 to rotate. At this time, the rotation of the second transmission wheel 3043 causes the first gear 3045 to start to rotate. Since the bottom of the first transmission rod 304 is connected to the connecting block 305 and the bottom of the connecting block 305 is connected to the eccentric block 306, and the connecting block 305 and the eccentric block 306 are connected. The center of the circle of block 306 is not on the same axis, which makes the connecting rod 401 start to rotate coaxially in different directions. When the connecting rod 401 starts to move, the arc surface of the first arc surface block 402 moves at the bottom of the first limit fixing ring 307, and the arc surface of the second arc surface block 404 moves at the top of the second limit fixing ring 308. In this way, the stability of the movement of the device can be ensured when the connecting rod 401 moves. At this time, the second gear 403 starts to rotate with the rotation of the connecting rod 401, and the first gear 3045 and the second gear 403 are adapted to each other, so that the connecting rod 401 can realize the rotation movement along its own central axis. At this time, the first agitator 405 and the second agitator 407 installed on the connecting rod 401 are connected. The connecting rod 401 rotates coaxially with the stirring rod 406 in the glue tank 2 in opposite directions, so that the connecting rod 401 can reduce the generation of bubbles through its unique flow pattern and improve the efficiency of bubble discharge, and at the same time help to reduce the dead corners and unmixed areas of the glue tank 2 and improve the uniformity of glue mixing. At this time, the vacuum pump 204 is started to evacuate the glue tank 2 through the vacuum tube 203 to eliminate the air inside the glue; then the glue flows into the proportion regulator 206 and flows into the glue applicator 501 through the glue outlet pipe 508, and then according to the size of the inner voice coil 608, the regulator 504 is rotated. At this time, one end of the regulator 504 is against the round block 503 and squeezes the bristles 507 through the clamping plate 502, so that the bristles 507 and the inner voice coil 608 are aligned. The contact area changes by rotating the regulator 504, and then the clamp block 6072 is opened to both sides and the inner voice coil 608 is placed on the clamp block 6072, and the inner voice coil 608 is clamped by the spring 6071. In order to prevent the clamping force of the clamp block 6072 from being too large, a soft pad 6073 is installed on the inner side of the clamp block 6072, and then the push rod 601 is pulled to make the block 602 drive the bar tooth 603 to move horizontally and drive the third gear 604 to start rotating. When the third gear 604 starts to rotate, the placement block 607 starts to rotate. In order to ensure that the placement block 607 rotates conveniently, a rotating shaft 606 is installed at the bottom of the support rod 605 to reduce friction and energy loss, thereby improving the transmission efficiency of the third gear 604.
