Description

Technical Field

[0001] The invention relates to the technical field of loudspeakers, and in particular to an automatic pressing machine for loudspeaker production. Background Art

[0002] A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in audio equipment, but it is also the most important component for sound effects. There are many types of speakers, and the prices vary greatly. Audio electrical energy is transmitted through electromagnetic, piezoelectric or electrostatic effects, causing the cone or diaphragm to vibrate and resonate (resonate) with the surrounding air to produce sound. Low-end plastic speakers have no sound quality because of their thin cabinets and inability to overcome resonance (some well-designed plastic speakers are far better than inferior wooden speakers). Wooden speakers reduce the sound coloration caused by cabinet resonance, and the sound quality is generally better than plastic speakers.

[0003] There are many types of speakers. According to their transducer principles, they can be divided into electric (i.e. moving coil), electrostatic (i.e. capacitive), electromagnetic (i.e. reed), piezoelectric (i.e. crystal) and other types. The latter two are mostly used in rural cable radio networks. According to the frequency range, they can be divided into low-frequency speakers, medium-frequency speakers, and high-frequency speakers. These are often used as combination speakers in sound boxes.

[0004] The speakers need to be collected after pressing during production. However, after pressing, the product may be relatively tight to the pressing mold. Therefore, when collecting, the air between the speaker product and the pressing mold may be discharged after pressing. This will increase the adhesion between the speaker and the pressing mold, making it inconvenient to collect. Summary of the invention

[0021] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0022] 1. Start the rotary motor. The rotation of the rotary motor drives the cross gear 1 to rotate. The rotation of the cross gear 1 drives the cross gear 2 to rotate. The rotation of the cross gear 2 squeezes the arc plate. The arc plate is moved up and down by the action of the spring 3 on the arc plate. The up and down movement of the arc plate drives the rectangular L-shaped rod to move up and down. The up and down movement of the rectangular L-shaped rod presses the speaker. The cross gear 2 is connected to the roller of the transport conveyor belt.

[0023] 2. Through the design of the cross gear 1 and the cross gear in the shape of a figure 20, the cross gear 2 will stop rotating when it rotates, which will cause the conveyor belt to stop moving. In this way, the pressing can be completed by using the time of the conveyor belt moving stop, thereby making full use of the mechanical coordination between the devices, ensuring the operation of the entire device and making it run more stably.

[0024] 3. The rotation of the rotating motor drives the rotation of , which drives the rotation of , which drives the circular turntable to rotate. The rotation of the circular turntable drives the short round rod to rotate. The rotation of the short round rod drives the arc rod to shift back and forth. The back and forth shift of the arc rod drives the rectangular cross bar to move left and right. The left and right movement of the rectangular cross bar will squeeze the horizontal exhaust pipe back and forth, so that the horizontal exhaust pipe will discharge gas intermittently, and the discharged gas will be blown to the pressing mold at the lower end of the conveyor belt, thereby ensuring that the pressed speaker in the pressing mold falls into it, completing the collection of the speaker.

[0025] 4. By arranging spring 1 and a small vibrating ball at the lower end of the pressing mold and spring 2 at the lower end of the cone, when the gas blown out from the horizontal exhaust pipe hits the pressing mold, it will vibrate back and forth. The vibration can further ensure the falling of the pressed speaker in the pressing mold, thereby further ensuring the collection of the speaker.

[0026] 5. This device can complete the pressing, transportation and collection of the speakers through a power source rotating motor, thereby reducing the increase of power sources and achieving the purpose of energy-saving production. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Working principle:

[0047] Step 1: Place the speaker to be pressed into the pressing mold 2, and press it with a pneumatic pressing machine. After the pressing is completed, it is transported to 49 via the transport conveyor belt 10;

[0048] Step 2: Start the rotating motor 3. The rotation of the rotating motor 3 drives the cross gear 1 31 to rotate. The rotation of the cross gear 1 31 drives the cross gear 2 32 to rotate. The rotation of the cross gear 2 32 squeezes the arc plate 33. The arc plate 33 moves up and down through the action of the spring 35 on the arc plate 33.

[0049] Step 3: By using the cross-shaped design of the cross-shaped gear 1 31 and the cross-shaped gear 2 32, the cross-shaped gear 2 32 will stop rotating when rotating, which will cause the conveyor belt 10 to stop moving. In this way, the pressing can be completed during the stop time of the conveyor belt 10, thereby making full use of the mechanical coordination between the devices to ensure the operation of the entire device and make it run more stably.

[0050] Step 4: The rotation of the rotating motor 3 drives the rotation of 60, the rotation of 60 drives the rotation of 61, the rotation of 61 drives the circular turntable 42 to rotate, the rotation of the circular turntable 42 drives the short round rod 48 to rotate, the rotation of the short round rod 48 drives the arc rod 47 to shift back and forth, the back and forth shift of the arc rod 47 drives the rectangular cross bar 45 to move left and right, the left and right movement of the rectangular cross bar 45 will squeeze the horizontal exhaust pipe 51 back and forth, so that the horizontal exhaust pipe 51 intermittently discharges gas outward, so that the discharged gas will be blown to the pressing mold 2 located at the lower end of the transport conveyor belt 10, so as to ensure that the loudspeaker pressed in the pressing mold 2 falls into 49, completing the collection of the loudspeaker;

[0051] Step 5: By arranging a spring 1 22 and a vibrating small ball 21 at the lower end of the pressing mold 2 and a spring 2 24 at the lower end of the cone 23, when the gas blown out from the horizontal exhaust pipe 51 hits the pressing mold 2, it will vibrate back and forth, and the vibration can further ensure the falling of the speaker that has been pressed in the pressing mold 2, thereby further ensuring the collection of the speaker;
