Description

Technical Field

[0001] The utility model relates to the technical field of plastic edge pressing, in particular to a plastic edge pressing device for processing a loudspeaker. Background Art

[0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great impact on the sound quality. Audio power vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates with the surrounding air to produce sound. There are many types of loudspeakers. According to their transducer principles, they can be divided into electric, electrostatic, electromagnetic, and piezoelectric types. The latter two are mostly used in rural cable broadcasting networks. According to the frequency range, they can be divided into low-frequency speakers, mid-frequency speakers, and high-frequency speakers. These are often used as combination speakers in sound boxes. The production of loudspeakers is a complex process, and the process requires the use of plastic edge pressing devices.

[0003] A Chinese patent discloses a plastic edge pressing device for speaker processing with a publication number of CN219214130U. The device is arranged by placing a component so that after the speaker completes the plastic edge pressing operation in the placement groove, the ejection cylinder can push the ejection plate to push, thereby driving the ejection plate to slide in the placement groove to eject the speaker, thereby preventing the speaker from being stuck in the placement groove during the edge pressing operation, which is beneficial to the unloading of the speaker. However, the device only pushes the speaker out of the placement groove and cannot complete the unloading of the speaker. The speaker needs to be removed manually, and the working efficiency is low.

[0004] In order to solve the above problems, we have made improvements and proposed a plastic edge pressing device for speaker processing. Utility Model Content

The second hydraulic telescopic rod 10 is connected to the first cross plate 7 through a flange plate, which keeps the first cross plate 7 stable, and the first hydraulic telescopic rod 2 is provided to shorten the stroke of the second hydraulic telescopic rod 10, so that the operation of the upper die base 18 is more stable;

[0022] The speaker and the plastic parts are placed in the placement groove 12, the first hydraulic telescopic rod 2 contracts to lower the top plate 3, and then the second hydraulic telescopic rod 10 extends to make the buffer assembly and the upper mold base 18 move downward, and the upper mold base 18 and the lower mold base 11 cooperate to perform the edge pressing operation on the speaker. After the edge pressing is completed, the upper mold base 18 is reset. At this time, the first cylinder 15 and the second cylinder 16 work to lift the push plate 13, and then push the speaker out of the placement groove 12. When the push plate 13 moves out of the placement groove 12, the first cylinder 15 reaches the maximum stroke. At this time, the second cylinder 16 continues to work, so that the push plate 13 tilts forward around the hinge point with the first cylinder 15, and the speaker presses the push plate 13 to slide forward, realizing automatic blanking and improving work efficiency. The first hydraulic telescopic rod 2 and the second hydraulic telescopic rod 10 are set to realize the secondary stroke, which can increase the distance between the upper mold base 18 and the lower mold base 11, and facilitate the loading of the speaker.

[0023] Specifically, Figure 1 and Figure 2 As shown, the buffer assembly includes a first cross plate 7, and the first cross plate 7 is fixedly connected to the bottom end of the second hydraulic telescopic rod 10, a second cross plate 9 is arranged below the first cross plate 7, and an upper die seat 18 is fixedly connected to the bottom end of the second cross plate 9, the first cross plate 7 is fixedly connected to the second cross plate 9 through a plurality of elastic telescopic rods 8, when the second hydraulic telescopic rod 10 moves downward, the upper die seat 18 acts on the lower die seat 11, the elastic telescopic rod 8 contracts, and the second cross plate 9 approaches the first cross plate 7, so as to avoid a rigid collision between the upper die seat 18 and the lower die seat 11, thereby protecting the equipment.

[0024] Specifically, Figure 3 As shown, a pad block 17 is fixedly connected to the bottom end of the first cylinder 15, and the pad block 17 is fixedly connected to the bottom end of the mounting cavity 14. The stroke of the first cylinder 15 is smaller than the stroke of the second cylinder 16.

The fixing rod 5 is connected to the guide columns 4 through the connecting plate 6 to fix the guide columns 4 to avoid deformation of the guide columns 4 themselves.

[0026] Specifically, Figure 3 As shown, a partition block is provided between the placement groove 12 and the installation cavity 14, and the output ends of the first cylinder 15 and the second cylinder 16 both pass through the partition block. The partition block supports the push plate 13 in the initial state to prevent the force of the speaker from being transmitted to the first cylinder 15 and the second cylinder 16 during the edge pressing process, thereby protecting the first cylinder 15 and the second cylinder 16.

[0027] Working principle: the loudspeaker and plastic parts are placed in the placement groove 12, the first hydraulic telescopic rod 2 contracts to lower the top plate 3, and then the second hydraulic telescopic rod 10 extends to make the buffer assembly and the upper die seat 18 move downward, the upper die seat 18 acts on the lower die seat 11, the elastic telescopic rod 8 contracts, and the second cross plate 9 approaches the first cross plate 7 to avoid rigid collision between the upper die seat 18 and the lower die seat 11. The upper die seat 18 and the lower die seat 11 cooperate to perform edge pressing on the loudspeaker. After the edge pressing is completed, the upper die seat 18 is reset. At this time, the first cylinder 15 and the second cylinder 16 work to lift the push plate 13, and then push the loudspeaker out of the placement groove 12. When the push plate 13 moves out of the placement groove 12, the first cylinder 15 reaches the maximum stroke.
