[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-5The present invention provides an efficient pressing fixture for audio parts, comprising a workbench 1, a bracket 2 located on the workbench 1, a first pressing assembly 3 installed on the bracket 2 in a lifting manner, and a second pressing assembly 4 installed on the workbench 1 in a sliding manner, wherein a first driving member 21 is fixed on the bracket 2, the first pressing assembly 3 is connected to the output end of the first driving member 21, and the first pressing assembly 3 is suspended above the second pressing assembly 4 through the first driving member 21, the first pressing assembly 3 comprises a first fixed pressing plate 31 connected to the first driving member 21 and a first movable pressing plate 32 elastically connected below the first fixed pressing plate 31, a mounting seat 321 is provided on the upper surface of the first movable pressing plate 32, a first elastic pressing rod 322 is penetrated on the mounting seat 321, the elastic action direction of the first elastic pressing rod 322 is perpendicular to the driving direction of the first driving member 21, and the first fixed pressing plate 31 A spring-pressing trigger block 311 for triggering the movement of the first spring-pressing rod 322 is fixed to the lower surface, and an elastic pressure plate 323 is provided at one end of the first spring-pressing rod 322 relatively away from the spring-pressing trigger block 311. The second pressing assembly 4 includes a second fixed pressure plate 41 and a second movable pressure plate 42 elastically connected above the second fixed pressure plate 41. The upper surface of the second movable pressure plate 42 is provided with a hemispherical placement groove 421 for assembling and positioning the spherical speaker, and the arc-shaped placement groove is provided with a ring-shaped plug plate 422 for plugging into the opening of the spherical speaker. A through hole 4211 is provided on the inner wall of the hemispherical placement groove 421 to communicate with the lower surface of the second movable pressure plate 42, and a second spring-pressing rod 423 is embedded in the through hole 4211 and is arranged to abut the second fixed pressure plate 41. The elastic action direction of the second spring-pressing rod 423 coincides with a certain diameter extension direction of the hemispherical placement groove 421.

[0028] Before use, first fit the accessories to the corresponding positions on the spherical speaker opening and the inner wall, and then insert the spherical speaker opening downward on the annular plug plate 422, so that the spherical speaker is placed in the hemispherical placement groove 421. The second pressing component 4 drives the spherical speaker to slide to the bottom of the first pressing component 3, and the first driving member 21 drives the first fixed pressing plate 31 to move downward and drives the first movable pressing plate 32 to elastically abut against it and move downward until the first movable pressing plate 32 contacts the spherical speaker. As the first fixed pressing plate 31 moves further downward, elastic energy storage is formed between the first movable pressing plate 32 and the first fixed pressing plate 31, so that the first movable pressing plate 32 abuts against the upper edge of the spherical speaker opening, and the lower edge of the spherical speaker opening abuts against the inner wall of the hemispherical placement groove 421. Elastic energy is formed between the plate 42 and the second fixed pressure plate 41, so that accessories such as PSA, MLB, and light-guiding foam attached to the edge of the opening of the spherical speaker can be completely pressed and fixed; when elastic energy is formed between the second movable pressure plate 42 and the second fixed pressure plate 41, the distance between the two is reduced, so that the second spring rod 423 extends out of the through hole 4211 and abuts against the outer wall of the spherical speaker in the hemispherical placement groove 421, so that accessories such as sound insulation foam attached to the outer wall can be completely pressed and fixed; when the first fixed pressure plate 31 moves downward, the spring trigger block 311 moves downward synchronously, and the movement of the spring trigger block 311 triggers the movement of the first spring rod 322, so that the elastic pressure plate 323 abuts and presses against the inner wall of the spherical speaker, so that accessories such as Mylar attached to the inner wall can be completely pressed and fixed.

[0029] The present invention sets a first driving member 21 to drive and trigger multi-point pressing. The operator only needs to fit multiple accessories in position in advance, and then put them into the second pressing member and start the machine to complete the one-time pressing of multiple accessories. By setting each pressing point and the contact surface of the product to be elastic pressing, it is avoided that the product and accessories are damaged due to excessive hardness when being pressed and fixed, which affects the product quality. The present invention has a fast installation speed for product accessories, effectively reduces labor costs, improves production efficiency, and reduces the number of driving member actions, thereby reducing energy consumption and reducing production costs.

[0030] In the embodiment of the present invention, the first driving member 21 is preferably a driving cylinder whose driving direction is perpendicular to the workbench 1. Specifically, the driving cylinder is fixedly installed on the top of the bracket 2, and the output end passes through the top plate of the bracket 2 and extends downward to connect to the first fixed pressure plate 31. By controlling the lifting and lowering movement of the first fixed pressure plate 31, the linkage of other components is driven.

[0031] In order to increase the lifting stability of the driving cylinder and avoid shaking during the lifting process, the output end of the driving cylinder in the embodiment of the present invention is fixedly connected to a balance plate 211, and the lower surface of the balance plate 211 is fixedly connected to the first fixed pressure plate 31. Vertical limit rods 212 are respectively fixed to the four corners of the balance plate 211. The end of the limit rod 212 away from the balance plate 211 passes through the bracket 2 and extends upward. Therefore, when the driving cylinder is operating, the limit rod 212 forms a limiting effect on the four corners of the balance plate 211 to prevent the balance plate 211 from tilting, causing the first pressing assembly 3 to be pressed downward and deviate, affecting the pressing effect.

[0032] The second fixed pressure plate 41 in the embodiment of the present invention is provided with a boss 411 for abutting the lower end of the second spring rod 423. The upper end of the boss 411 is a truncated cone with a narrow upper part and a wide lower part. The lower end of the second spring rod 423 abuts on the hypotenuse of the upper end of the boss 411. Since the second spring rod 423 always maintains relative oblique movement relative to the second first movable pressure plate 32, the setting of the boss 411 can support the second spring rod 423 and the second fixed pressure plate 41 to maintain an oblique abutment state, thereby facilitating the second fixed pressure plate 41 to obliquely abut and push out the second spring rod 423 when the second first movable pressure plate 32 moves downward.

[0033] The mounting seats 321 in the present invention are symmetrically arranged with two on the upper surface of the first movable pressure plate 32, and the first elastic pressure rods 322 and the elastic pressure plate 323 are each equipped with two corresponding mounting seats 321, and the movement directions of the two first elastic pressure rods 322 are opposite, so that the two elastic pressure rods can synchronously press and fix the symmetrically fitted heat dissipation foam in the spherical speaker.

[0034] The elastic pressure plate 323 in the embodiment of the present invention is provided with a rubber pad 3231 on one side corresponding to the contact with the inner wall of the spherical speaker. The outer contact surface of the rubber pad 3231 is a slope 3232, so that the rubber pad 3231 fits more closely with the inner wall of the spherical speaker, ensuring the balance of the center of gravity of the force, and avoiding uneven pressure that causes too little pressure on the corners and insufficient fit, which may cause the accessories to fall off.

[0035] The workbench 1 in the embodiment of the present invention is provided with two parallel slide rails 11, and a slider 12 is slidably connected to the slide rails 11, and the slider 12 is fixedly connected to the lower surface of the second fixed pressure plate 41, and one end of the slide rail 11 is located directly below the bracket 2, and a position avoidance hole 13 is opened on the workbench 1 between the two slide rails 11, and a second driving member 14 is embedded in the position avoidance hole 13, and a connecting plate 15 is provided on the lower surface of the second fixed pressure plate 41 at a position corresponding to the position avoidance hole 13, and the output end of the second driving member 14 is fixedly connected to the connecting plate 15 The second fixed pressing plate 41 is driven to slide on the workbench 1 by the second driving member 14, thereby driving the relative position between the second pressing assembly 4 and the first pressing assembly 3 to move. When the second pressing assembly 4 is located at the end of the slide rail 11 away from the pressing assembly, the operator places the spherical sound to be pressed on the second pressing assembly 4, and the second pressing assembly 4 moves along the slide rail 11 to drive the spherical sound to the bottom of the first pressing assembly 3 for pressing. Therefore, the second pressing assembly 4 plays a role of transportation on the one hand, and on the other hand, there is a pressure point involved in the pressing action.

[0036] The second driving member 14 in the embodiment of the present invention is preferably a ball screw pair whose driving direction is parallel to the slide rail 11. Since the second driving member 14 is embedded in the workbench 1, in order to avoid the workbench 1 being too large and cumbersome, the second driving member 14 adopts a ball screw pair to ensure sufficient driving distance while avoiding excessive bulk of the equipment.

[0037] In the embodiment of the present invention, two through holes 4211 are symmetrically arranged in the hemispherical placement groove 421, and two second elastic pressure rods 423 are arranged corresponding to the through holes 4211. The intersection of the elastic movement directions of the two second elastic pressure rods 423 is the center point of the hemispherical placement groove 421, so that the force applied when the spherical audio accessories are pressed is balanced.

[0038] Regarding the elastic connection between the first movable pressure plate 32 and the first fixed pressure plate 31, specifically, a plurality of connecting rods 312 are passed through the first fixed pressure plate 31, and one end of the connecting rod 312 protruding from the upper surface of the first fixed pressure plate 31 is provided with a limit block 313 for limiting the maximum downward movement of the connecting rod 312 relative to the first fixed plate, and the other end is fixed to the first movable pressure plate 32, and a spring 314 is sleeved on the connecting rod 312, and the two ends of the spring 314 respectively abut against the first movable pressure plate 32 and the first fixed pressure plate 31. 31 moves downward under the drive of the first driving member 21, and the first movable pressure plate 32 abuts against the product to limit further downward movement, so the spring 314 between the first movable pressure plate 32 and the first fixed pressure plate 31 is squeezed and deformed, and the connecting rod 312 protrudes relatively from the upper surface of the first fixed pressure plate 31 and moves upward. By setting an elastic connection between the first movable pressure plate 32 and the first fixed pressure plate 31, the first movable pressure plate 32 has good buffering properties when contacting and pressing the product, and will not generate excessive stress, so that the pressing effect remains good and the product quality is not damaged.

[0039] It should be noted that other elastic connection principles in the embodiment of the present invention are similar to those of the first movable pressing plate 32 and the first fixed pressing plate 31 , and therefore they will not be described in detail.

[0040] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
