Description

Technical Field

[0001] The present invention belongs to the technical field of loudspeaker equipment, and more specifically, particularly relates to a hot pressing forming device for a loudspeaker diaphragm. Background Art

[0002] The diaphragm of a speaker is an important part of the speaker, usually made of metal, plastic or paper. The diaphragm is used to vibrate, thereby producing sound. When the speaker receives an electrical signal, the current passes through the coil to generate a magnetic field, causing the diaphragm to vibrate. This vibration causes the surrounding air to compress and rarefy, which in turn produces sound fluctuations. The vibration frequency and amplitude of the diaphragm determine the pitch and volume of the sound produced by the speaker. Factors such as the material, thickness and shape of the diaphragm will affect the quality of the sound, so it is very important to choose the right diaphragm material and structure when designing a speaker.

[0003] After the hot pressing forming is completed, the existing device needs to use multiple independent mechanisms to realize the transmission of the diaphragm, which greatly increases the complexity of the whole process and the difficulty of coordination and cooperation between the various mechanisms. If the action connection between different mechanisms may not be tight enough, it is easy to pause or delay, affecting the production efficiency. Multiple independent mechanisms also mean higher equipment and maintenance costs, occupying more space resources. The control and adjustment of these independent mechanisms during operation are also cumbersome. Once a mechanism fails, it is difficult to troubleshoot and repair it, which is easy to cause interruption and delay of the whole production process, greatly affecting the continuity and stability of production.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, a first transmission assembly is provided, and a motor is started. The motor drives the first transmission assembly to rotate clockwise, and the first transmission assembly drives the first missing gear to rotate clockwise, and the first missing gear drives the first gear to rotate intermittently counterclockwise, and the first gear drives the first connecting rod to rotate counterclockwise, and the first connecting rod drives the ratchet to rotate counterclockwise. When the ratchet rotates, the pawl is squeezed, so that the pawl squeezes the spring rod, and the spring rod is compressed by force, and the first connecting rod drives the winding roller to rotate counterclockwise, so that the diaphragm rotates out of the side wall of the winding roller. At the same time, the first transmission assembly drives the second missing gear to rotate clockwise, and the second missing gear drives the second gear to rotate intermittently counterclockwise, and the second gear drives the first transmission shaft to rotate counterclockwise, and the first transmission shaft drives the counterclockwise transmission, and the synchronous belt drives the second transmission shaft to transmit counterclockwise, and the second transmission shaft drives the second transmission assembly to transmit counterclockwise, and the second transmission assembly drives the third transmission shaft to rotate counterclockwise, and the third transmission shaft drives the synchronous belt to transmit counterclockwise, and the synchronous belt drives the fourth transmission shaft to transmit counterclockwise, and the intermittent rotation gives the device enough stamping and cutting time, reduces the process of device transmission, and improves the efficiency of device transmission.

[0017] In the present invention, a mounting plate is provided, and the cylinder is started. The cylinder drives the pneumatic rod to continuously contract and extend, and the pneumatic rod drives the mounting plate to reciprocate up and down. The mounting plate drives the hot press and the cutting knife to continuously reciprocate up and down. When the diaphragm is transmitted to the bottom of the hot press, the hot press and the hot pressing plate cooperate to hot-press the diaphragm into shape. When the diaphragm is transmitted to the bottom of the cutting knife, the cutting plate and the cutting knife cooperate to cut the diaphragm, thereby reducing the use of additional driving devices, reducing equipment costs, and better ensuring the temporal connection between hot pressing and cutting actions, thereby improving work efficiency.

[0018] In the present invention, a clamping plate is provided, the winding roller is inserted into the interior of the first connecting rod, the second connecting rod is rotated counterclockwise, the angle of the second connecting rod is adjusted, and the threaded rod is rotated counterclockwise. The threaded rod drives the sliding clamping plate to move in the direction of the winding roller until the second connecting rod is inserted into the interior of the winding roller and the winding roller is fixed, thereby achieving the function of facilitating the fixing of winding rollers of different widths.

[0019] In the present invention, a sliding pallet is provided to pull the diaphragm out from the inside of the winding roller, and the diaphragm is pulled through between the sliding pallet and the fixed pallet. The screw rod is rotated counterclockwise, and the screw rod drives the third transmission component to transmit counterclockwise. The third transmission component drives the diaphragm to slide from bottom to top along the inside of the base. The sliding pallet will gradually approach the fixed pallet and drag the diaphragm, thereby achieving the function of facilitating the lifting of diaphragms of different thicknesses.

[0020] In the present invention, a collection box is provided, and the cut diaphragm falls into the collection box. The diaphragm will slide along the inclined surface of the wedge block until it contacts the baffle, so that the diaphragm is accumulated inside the collection box. When the diaphragm inside the collection box is full, the rotating clamping column is rotated from the middle to both sides, and the rotating clamping column will be separated from the side wall of the baffle. The baffle is then flipped counterclockwise to change the collection box from a closed state to a semi-open state. The diaphragm will slide out of the collection box along the inclined surface of the wedge block for collection, which prevents the diaphragm from falling out of the device and being contaminated, and is also convenient for staff to collect, thereby achieving the function of facilitating collection by staff.

[0036] Working principle:

[0037] The first step is to insert the winding roller 52 into the first connecting rod 16, rotate the second connecting rod 33 counterclockwise, adjust the angle of the second connecting rod 33, and then rotate the threaded rod 51 counterclockwise. The threaded rod 51 drives the sliding clamping plate 31 to move in the direction of the winding roller 52 until the second connecting rod 33 is inserted into the winding roller 52 and the winding roller 52 is fixed, thereby achieving the function of facilitating the fixing of winding rollers 52 of different widths.

[0038] In the second step, the diaphragm is pulled out from the inside of the winding roller 52, and the diaphragm is pulled through the sliding support plate 34 and the fixed support plate 37, and the screw rod 35 is rotated counterclockwise. The screw rod 35 drives the third transmission assembly 36 to transmit counterclockwise, and the third transmission assembly 36 drives to slide from bottom to top along the inside of the base 11. The sliding support plate 34 will gradually approach the fixed support plate 37 to support the diaphragm, thereby achieving the function of facilitating the lifting of diaphragms of different thicknesses.

[0039] The third step is to start the motor 12, the motor 12 drives the first transmission assembly 13 to rotate clockwise, the first transmission assembly 13 drives the first missing gear 14 to rotate clockwise, the first missing gear 14 drives the first gear 15 to rotate counterclockwise intermittently, the first gear 15 drives the first connecting rod 16 to rotate counterclockwise, the first connecting rod 16 drives the ratchet 17 to rotate counterclockwise, the ratchet 17 squeezes the pawl 18 when rotating, so that the pawl 18 squeezes the spring rod 19, so that the spring rod 19 is compressed, the first connecting rod 16 drives the winding roller 52 to rotate counterclockwise, so that the diaphragm rotates out of the side wall of the winding roller 52, and at the same time the first transmission assembly 13 drives the second missing gear 21 clockwise. The needle rotates, the second missing gear 21 drives the second gear 22 to rotate counterclockwise intermittently, the second gear 22 drives the first transmission shaft 23 to rotate counterclockwise, the first transmission shaft 23 drives counterclockwise transmission, the synchronous belt 28 drives the second transmission shaft 24 counterclockwise, the second transmission shaft 24 drives the second transmission assembly 25 counterclockwise, the second transmission assembly 25 drives the third transmission shaft 26 to rotate counterclockwise, the third transmission shaft 26 drives the synchronous belt 28 counterclockwise, the synchronous belt 28 drives the fourth transmission shaft 27 counterclockwise, and the intermittent rotation gives the device enough stamping and cutting time, reduces the device transmission process, and improves the device transmission efficiency.

[0040] The fourth step is to start the cylinder 38, which drives the pneumatic rod 39 to continuously contract and stretch, and the pneumatic rod 39 drives the mounting plate 41 to reciprocate up and down. The mounting plate 41 drives the hot press 42 and the cutting knife 43 to continuously reciprocate up and down.

[0041] In the fifth step, the cut diaphragm falls into the collection box 47, and the diaphragm will slide along the inclined surface of the wedge block 48 until it contacts the baffle 49, so that the diaphragm is accumulated inside the collection box 47. When the diaphragm inside the collection box 47 is full, the rotating clamping column 46 is rotated from the middle to both sides, and the rotating clamping column 46 will be separated from the side wall of the baffle 49, and then the baffle 49 is flipped counterclockwise to change the collection box 47 from a closed state to a semi-open state. The diaphragm will slide out of the collection box 47 along the inclined surface of the wedge block 48 for collection, preventing the diaphragm from falling out of the device and being contaminated, and also facilitating collection by the staff, thereby achieving the function of facilitating collection by the staff.
