Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and particularly relates to a loudspeaker paper cone pressing device. Background Art

[0002] The paper cone is an important part of the loudspeaker. As a diaphragm for radiating sound waves, it is a key component for the sound output of the loudspeaker. The paper cone, also known as the speaker cone, is a key element in the loudspeaker system for converting electrical signals into sound waves. Its main function is to cause the vibration of the paper cone through the drive of electrical signals, thereby generating sound waves. The material of the paper cone can be pure paper or a composite material made by mixing with other fibers.

[0003] Currently, there is a paper cone made of rubber material as Figure 1 shown, which includes a vibrating plate and a surround. During the process of manufacturing the paper cone, it is necessary to fix the vibrating plate and the surround together. The prior art usually fixes the vibrating plate and the surround together by the staff using the method of applying glue.

[0004] In the above solution, this method of manufacturing the paper cone has low efficiency, and during the process of applying glue, the glue is easily contaminated to other parts, which will affect the quality of the final product. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a loudspeaker paper cone pressing device. By providing a positioning module and a hot pressing die head, the surround and the vibrating plate can be quickly bonded and fixed, solving the problem of low efficiency in the method of manufacturing the paper cone in the prior art, and ensuring that the quality of the paper cone is not affected.

[0006] The solution of the utility model to solve the above technical problem is:

[0007] A loudspeaker paper cone pressing device includes a frame. Two screws are symmetrically fixed at the upper end of the frame. A pressing plate is inserted on the side wall of the screw, and a nut is screwed on the side wall of the screw. A workbench is placed at the upper end of the frame. A buffer assembly is provided at the upper end of the workbench, and a positioning module is provided on the buffer assembly. A pressing component and a stacking component are provided at the upper end of the frame, and a hot pressing die head is provided on the pressing component.

[0008] When making a paper cone, place the workbench at the upper end of the frame and set the workbench coaxially with the hot pressing die head. Drive the pressing plate to press against the upper end of the workbench. Rotate the nut to fix the pressing plate, so that the workbench is fixed at the required position. Place the vibrating plate on the upper end of the positioning module, and then place the surround on the upper end of the positioning module. Under the action of the positioning module, position the vibrating plate and the surround. Start the pressing assembly to drive the hot pressing die head to move downward to hot press the overlapping part of the surround and the vibrating plate, melt the rubber at the overlapping part of the surround and the vibrating plate, and press them together, so that the surround and the vibrating plate are adhesively fixed, thus making the paper cone. Then place the paper cone socket in the stacking assembly to stack several paper cones neatly, which is convenient for collecting the paper cones.

[0009] By providing a positioning module and a hot pressing die head, the surround and the vibrating plate can be quickly adhesively fixed, solving the problem of low efficiency in the existing method of making paper cones and ensuring that the quality of the paper cone is not affected.

[0010] The utility model is further provided as follows: The buffer assembly includes a guiding groove formed at the upper end of the workbench. A guiding block matching with the guiding groove is fixed at the lower end of the positioning module. Multiple compression springs are fixed at the lower end of the positioning module, and the lower ends of the compression springs are fixed at the upper end of the workbench.

[0011] Through the above technical solution, when the pressing assembly drives the hot pressing die head to move downward for hot pressing, under the action of multiple compression springs, the impact force of the hot pressing die head on the positioning module can be reduced, thus improving the service life of the hot pressing die head and the positioning module.

[0012] The utility model is further provided as follows: The upper end of the positioning module is formed with a first positioning groove matching with the vibrating plate and a second positioning groove matching with the surround.

[0013] Through the above technical solution, the vibrating plate and the surround can be positioned, so that the hot pressing die head can hot press the overlapping part of the surround and the vibrating plate.

[0014] The utility model is further provided as follows: The pressing assembly includes a cylinder fixed at the upper end of the frame, and the hot pressing die head is fixed at the output end of the cylinder.

[0015] Through the above technical solution, when it is necessary to drive the hot pressing die head to move downward, start the cylinder, and thus the hot pressing die head can be driven to move downward.

[0016] The utility model is further provided as follows: The stacking assembly includes a support rod fixed at the upper end of the frame, and a stacking rod is inserted and placed on the side wall of the support rod.

[0017] Through the above technical solution, when a number of paper cones need to be neatly stacked, the paper cones are inserted and sleeved on the stacking rod, so that a number of paper cones can be neatly stacked, and the stacking rod can be removed, so as to facilitate driving a number of paper cones to be placed at the required position.

[0018] The utility model is further arranged as: the top end of the stacking rod is provided with a fillet.

[0019] Through the above technical solution, it is convenient to insert and sleeve the paper cone on the stacking rod.

[0020] The beneficial effects of the utility model are:

[0021] Compared with the prior art, by providing a positioning module and a hot pressing die head, the folding ring and the vibrating plate can be quickly bonded and fixed, solving the problem of low efficiency in the existing method of manufacturing paper cones, and ensuring that the quality of the paper cone is not affected.

Then insert and place the diaphragm in the stacking component to stack several diaphragms neatly, which is convenient for collecting the diaphragms.

[0032] By providing the positioning module 6 and the hot pressing die head 7, the surround 9 and the vibrating plate 8 can be quickly adhesively fixed, solving the problem of low efficiency in the existing method of making diaphragms and ensuring that the quality of the diaphragm is not affected.

[0033] The buffer assembly includes a guiding groove 501 formed at the upper end of the workbench 5.

[0043] Working principle:

[0044] When it is necessary to manufacture a paper basin, the workbench 5 is placed on the upper end of the frame 1, and the workbench 5 is coaxially arranged with the hot pressing die head 7. The pressing plate 3 is driven to press against the upper end of the workbench 5, and the nut 4 is rotated to fix the pressing plate 3, so that the workbench 5 is fixed at the required position. The vibrating plate 8 is placed in the first positioning groove 601, and then the folding ring 9 is placed in the second positioning groove 602. The air cylinder 12 is started to drive the hot pressing die head 7 to move downward to hot press the overlapping part of the folding ring 9 and the vibrating plate 8, so that the rubber at the overlapping part of the folding ring 9 and the vibrating plate 8 melts and is pressed together, and then the folding ring 9 and the vibrating plate 8 are bonded and fixed, so as to manufacture the paper basin. Then the paper basin is inserted and placed in the stacking rod 14, and a number of paper basins are stacked neatly, so as to facilitate the collection of the paper basins.
