Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sticking fixture, especially a kind of sticking fixture of loudspeaker sealing strip. BACKGROUND

[0002] The loudspeaker is a kind of electric sound converter that converts electric energy into sound energy, which is mainly composed of magnet, voice coil, diaphragm (also known as cone) and other parts. When audio current passes through the voice coil of the loudspeaker, the voice coil will be subjected to force in the magnetic field generated by the magnet. This force will periodically change direction and size with the change of audio current, and then drive the diaphragm to vibrate back and forth, transferring the vibration energy to the surrounding air, forming sound waves, so that we can hear the sound. The performance of the loudspeaker directly affects the sound quality and volume of the sound, and is one of the key components in the audio system, widely used in television, audio, computer, mobile phone and other audio output devices.

[0003] In the prior art, to prevent sound from leaking out of the gap of the loudspeaker, a sealing strip is usually pasted on the sound cavity end face of the loudspeaker shell, so as to ensure the integrity and clarity of the sound;

[0004] The Chinese utility model patent with publication number "CN202323451226.7" and patent name "A loudspeaker mounting shell sealing strip sticking jig" discloses a sticking jig. The patent records the technical scheme of "the sticking jig includes a jig main body, characterized in that: the jig main body is provided with a plurality of side-by-side arranged sticking units for positioning the sealing foam and the loudspeaker mounting shell. Each sticking unit includes a sticking groove arranged according to the shape of the sound cavity wall. The bottom of each sticking groove is provided with a plurality of positioning columns for positioning the sealing foam. The sealing foam is positioned in the sticking groove through the positioning columns. The rear end of the sticking groove is provided with a positioning block corresponding to the limiting notch of the loudspeaker mounting shell. The limiting notch is clamped on the positioning block. The sticking groove corresponds to the positioning of the loudspeaker mounting shell, and the corresponding positioning of the sound cavity wall and the sealing strip is realized."

[0005] However, in the actual use process of the sticking jig, when the sealing strip is pasted on the sound cavity wall end face of the loudspeaker shell, manual installation of the loudspeaker shell is required to paste the sealing strip together with the loudspeaker shell. However, the pressing force cannot be ensured to be the same every time when pressing manually. The workers will be tired after a long time of work, which will reduce the pressing force, so that the loudspeaker shell or the sealing strip cannot be tightly pasted together, thereby affecting the subsequent use effect of the loudspeaker. At the same time, it is time-consuming and laborious to press manually, and the sealing cotton core needs to be taken out after pasting, which is more troublesome, thereby reducing the work efficiency.

[0006] Therefore, in order to solve the above technical problems, the utility model provides a kind of loudspeaker sealing strip's pasting jig. Utility model content

[0007] The utility model discloses a kind of loudspeaker sealing strip's pasting jig, can effectively solve the problem in background art.

[0008] To achieve the above object, the technical scheme adopted by the utility model is as follows:

[0010] Preferably, the top surface of the loudspeaker shell is provided with positioning holes on four sides.

[0011] Preferably, the top surface of the sealing strip body is fixedly installed with a pasting layer, and the top surface of the pasting layer is fixedly installed with release paper, and the inner walls of the sealing strip body, the pasting layer and the release paper are respectively provided with positioning openings on four sides.

[0012] Preferably, the top surface of the pasting jig body is provided with a plurality of grooves, and the groove bottom surface is fixedly installed with a positioning ring, and the outer wall of the positioning ring is fixedly installed with a positioning block on four sides.

[0013] Preferably, the top surface of the pasting jig body is provided with a movable slot on four sides, and the inner wall of the movable slot is respectively provided with a sliding groove on two sides, the groove bottom of the movable slot is fixedly installed with a compression spring, and the top end of the compression spring is fixedly installed with a buffer column, the outer wall of the buffer column is respectively fixedly installed with a sliding block on two sides, and the sliding block is movably installed in the sliding groove, and the top end of the buffer column is further fixedly installed with a positioning rod.

[0014] Preferably, the concave seat is fixedly installed on the top surface of the pasting jig body in an inverted manner, and the left and right side walls of the concave seat are respectively provided with sliding openings, the cylinder is fixedly installed on the top surface of the concave seat, and the output end bottom end of the cylinder is fixedly installed with a pressing plate, and the left and right side walls of the pressing plate are respectively fixedly installed with sliding blocks and movably installed in the sliding openings.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In this invention, the sealing strip body can be fitted onto the outside of the positioning ring through the positioning port using the positioning ring and the positioning blocks on the four sides of the outer wall. It is then positioned and installed in the groove on the top surface of the adhesive jig body. After peeling off the release paper from the top surface of the sealing strip body to expose the adhesive layer, the positioning rods protruding from the four sides of the groove on the top surface of the adhesive jig body are inserted into the positioning holes on the speaker housing. This positions the speaker housing directly above the sealing strip body. Combined with the use of the clamping mechanism, the cylinder drive output end pushes the pressure plate downwards. The pressure plate presses down on the speaker housing, causing the speaker housing to move downwards and forcing the buffer column to slide along the sliding groove within the movable groove via the slider. After moving downwards, the compression spring is forced to tighten, which provides a downward elastic buffer to the speaker housing, preventing it from being crushed. At this time, the sealing strip body will be tightly adhered to the end face of the speaker housing's acoustic cavity wall through the adhesive layer, thus achieving the purpose of quick adhesion between the sealing strip body and the speaker housing. This not only improves work efficiency but also eliminates the need for manual pressing of the speaker housing to adhere the sealing strip body to the speaker housing. The adhesion operation is time-saving, labor-saving, and quick, ensuring that each speaker housing and sealing strip body on the adhesion fixture body can be tightly adhered together, and ensuring the normal use effect of the speakers after production.
