Description

TECHNICAL FIELD

[0001] The application relates to the technical field of buzzer diaphragm manufacturing, in particular to a mold for assembling buzzer diaphragms. BACKGROUND

[0002] As a common sound-producing element, buzzer diaphragms are widely used in various electronic products. When assembling a buzzer diaphragm for an electric vehicle, a PVC diaphragm needs to be bonded to a piezoelectric ceramic sheet by using glue, and the back of the ceramic sheet and a metal sheet part need to be welded together. In this process, an assembling mold needs to be used. Workers first place the ceramic sheets into the placing grooves of the mold, then glue is applied and the diaphragm is placed, and after solidification, all the ceramic sheets are turned over and transferred to a welding machine for welding.

[0003] However, if the ceramic sheets are turned over individually during the turning process using a conventional mold, the efficiency is relatively low, and when the entire mold is turned over, the ceramic sheets will fall off due to gravity without being shielded. Therefore, there are certain deficiencies. CONTENT OF THE INVENTION

[0004] In order to improve the assembly efficiency, the application provides a mold for assembling buzzer diaphragms.

[0007] According to the above technical solution, the buzzer diaphragm is first placed in the placing groove of the bottom plate, the first limiting block ensures the positional stability of the buzzer diaphragm when it is placed, and the buzzer diaphragm will not fall off from the bottom of the bottom plate; then the cover plate is placed on the bottom plate, the second limiting block prevents the buzzer diaphragm from falling off from the side of the cover plate after the mold is turned over and exposes the welding point; glue is applied above the buzzer diaphragm and the diaphragm is placed, and after the glue solidifies, the buzzer diaphragm is turned over and welded; the design of the fixing member enables the cover plate to be firmly fixed to the bottom plate, preventing the cover plate from loosening or falling off during use, and improving the overall reliability and safety of the mold. The overall turning of the mold is facilitated by this design, thereby improving the assembly efficiency.

[0008] Optionally, a plurality of positioning pins are arranged on the bottom plate, a plurality of positioning holes corresponding to the positioning pins are arranged on the cover plate, and the positioning pins and the positioning holes are in plug-in cooperation.

[0009] By adopting the technical scheme, accurate positioning between the cover plate and the bottom plate can be ensured, and assembly precision and stability are improved. The cover plate is placed on the bottom plate by sliding along the positioning pin, and assembly problems caused by position deviation are avoided.

[0010] Optionally, the fixing member comprises two folding plates arranged on two sides of the cover plate, and each of the two folding plates is provided with a clamping block. The bottom plate is provided with a clamping groove, and the clamping groove is provided with a sliding block arranged opposite to the clamping block. The clamping block and the sliding block are in mutual abutment, and the bottom plate is provided with an adjusting assembly for controlling the disengagement of the clamping block and the sliding block.

[0011] By adopting the technical scheme, after the cover plate is placed, the folding plate is pressed down, and the clamping block on the folding plate is fixed in the sliding block in the clamping groove, so that the cover plate is firmly fixed on the bottom plate, preventing the cover plate from loosening or falling off during assembly and overturning, and improving the safety and reliability of the assembly process. The addition of the adjusting assembly allows the clamping block and the sliding block to be separated as needed, facilitating the opening and closing of the cover plate and further enhancing the convenience of use.

[0012] Optionally, the adjusting assembly comprises an adjusting button, a connecting rod, an adjusting block, a spring and a driving member for driving the sliding block.

The connecting rod is provided with a spring, one end of the spring is fixedly connected to the bottom plate, and the other end abuts against the adjusting block.

[0013] By adopting the technical scheme, pressing the adjusting button, the connecting rod slides relative to the bottom plate and drives the adjusting block to move towards the inside of the bottom plate, which can conveniently control the disengagement of the sliding block and the clamping block, so as to realize the quick fixing and separation of the cover plate and the bottom plate. Specifically, when the adjusting button is pressed, the connecting rod pushes the adjusting block to move downward. Since the adjusting block is conical, the end of the adjusting block with a larger cross-sectional diameter is close to the adjusting button, so that the adjusting block gradually presses the driving member during downward movement, so that the driving member drives the sliding block to move away from the clamping block, so that the clamping block and the sliding block are separated, and the fixing is released. At the same time, the design of the spring makes the adjusting block reset under the action of the elastic force after the adjusting button is released, so as to ensure that the sliding block abuts against the clamping block again, and the fixing state is restored. This design is not only simple to operate, but also stable and reliable in structure.

[0015] Through the above technical scheme, the design of the hinged rod and the torsional spring enables the driving rod to rotate around the hinge point when subjected to external force, thereby changing the position of the poking rod. The other end of the driving rod contacts the side wall of the adjusting block, and when the adjusting button is pressed, the adjusting block pushes the driving rod to move, thereby causing the poking rod to drive the sliding block to move, finally removing the interference between the clamping block and the sliding block, and achieving the unlocking of the cover plate. The poking rod is designed in an L shape, which ensures that the force can be effectively transmitted in a limited space, improving the convenience and reliability of operation. The sliding block is arranged at the upper end of the poking rod, ensuring the smoothness of the unlocking action.

[0016] Optionally, the clamping block and the sliding block are both hemispherical.

[0017] Through the above technical scheme, in order to loosen the clamping block and the sliding block, when the cover plate needs to be opened, only a certain force is applied to move the sliding block and pull the folding plate, and the clamping state can be removed, which is simple and convenient to operate, ensuring the convenience and reliability of the mold in use.

[0018] Optionally, a connecting pipe is arranged in the adjusting hole, the connecting pipe is arranged outside the spring, and the connecting rod is in sliding fit with the connecting pipe.

[0019] Through the above technical scheme, when the adjusting button is pressed, the connecting rod moves along the connecting pipe, ensuring the movement path of the adjusting block, preventing the adjusting block from sagging due to gravity, and effectively protecting the spring from deformation, ensuring that the adjustment process is more stable and reliable.

[0020] Optionally, a rubber pad is arranged on the adjusting button.

[0021] Through the above technical scheme, the rubber pad has a certain anti-skid effect, which can prevent the slipping phenomenon caused by sweating fingers, and can also increase the service life of the adjusting button.
