[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-Figure 5 A metal audio speaker base welding device includes a base mechanism 1 and a supporting mechanism 2 installed on the upper end of the base mechanism 1, a speaker base body 7 is arranged on the supporting mechanism 2, a welding mechanism 8 is installed on the inner wall of the base mechanism 1, and the welding mechanism 8 includes a mechanical arm 81 and a welding head 82 installed on one side of the mechanical arm 81. Under the action of the mechanical arm 81, the position and direction of the welding head 82 can be adjusted in a wide range.

[0025] The supporting mechanism 2 includes a side plate 21 fixedly mounted on the upper end of one side of the bottom plate 11 and a transverse plate 22 fixedly mounted on both sides of the upper end of the side plate 21 . The mechanical arm 81 is fixedly mounted on the side plate 21 .

[0026] The base mechanism 1 includes a bottom plate 11 and a support column 12 installed at the upper end of the bottom plate 11. The support mechanism 2 is installed at the upper end of the bottom plate 11 through the support column 12. The bottom plate 11, the support column 12, the side plate 21, and the cross plate 22 are combined into the outer frame structure of this device to ensure the stability of this device.

[0027] The base mechanism 1 also includes a first guide groove 13 opened at the upper end of the bottom plate 11, and a placement slide 14 connected to the first guide groove 13 is provided at the upper end of the bottom plate 11. A groove 15 is opened on the inner wall of the side plate 21. The welding tool is placed on the placement slide 14, and the placement slide 14 slides on the bottom plate 11 through the first guide groove 13, so as to drive the welding tool to move.

[0028] The welding workpiece is arranged at the upper end of the slide plate 14 , and the welding head 82 of the welding mechanism 8 is located on one side of the speaker base body 7 . When the speaker base body 7 slides to a suitable position, its welding part is matched with the welding head 82 , which is convenient for welding the speaker base body 7 .

[0029] A first slide groove 23, a second slide groove 24 and a third slide groove 25 are provided on the side plate 21. A lower guide rail 26 and an upper guide rail 27 are provided on one side of the side plate 21. The lower guide rail 26 is slidably installed in the first slide groove 23, and one end of the upper guide rail 27 slides in the second slide groove 24 and the third slide groove 25 together.

[0030] The first slide groove 23 and the second slide groove 24 are both horizontal structures, and the third slide groove 25 is a vertical structure, wherein the first slide groove 23 is arranged at the lower end of the second slide groove 24, and the second slide groove 24 is connected to the third slide groove 25. In the initial state, one end of the lower guide rail 26 is arranged at a position of the first slide groove 23 close to the middle of the device, and one end of the upper guide rail 27 is also arranged at a position of the second slide groove 24 close to the middle of the device, but is arranged on one side of the third slide groove 25. The horizontal line formed by the lower guide rail 26 and the upper guide rail 27 on the same side is inclined to the ground, and the openings of the two upper guide rails 27 are larger than the openings of the two lower guide rails 26, which adapts to the shape of the speaker base body 7.

[0031] When the operator needs to weld the speaker base body 7, the operator first places the speaker base body 7 from top to bottom between the two lower guide rails 26 and the two upper guide rails 27. However, the upper end diameter of the speaker base body 7 is larger than the lower end diameter, and its inclination does not match the inclination angle of the lower guide rails 26. Therefore, the speaker base body 7 is not stable when it is connected. In order to solve this problem, the operator manually presses the speaker base body 7 downward, and the upper end side wall of the speaker base body 7 squeezes the upper guide rails 27 outward. The opening between 27 gradually becomes larger, and with the cooperation of the lower guide rail 26, it can gradually adapt to the speaker base body 7. When the upper end of the speaker base body 7 is gradually lower than the upper guide rail 27, the upper guide rail 27 is reset until the upper guide rail 27 is snapped onto the upper end of the speaker base body 7. The positioning and fixation of the speaker base body 7 can be completed, which is convenient for adapting to speaker base bodies 7 of different sizes. Under the action of the two lower guide rails 26 and the two upper guide rails 27, the speaker base body 7 can be installed at multiple points without tilting, with good positioning effect and simple operation.

[0032] The upper guide rail 27 and the lower guide rail 26 are guide rail structures. The speaker base bodies 7 on the same production line have the same model. After the first speaker base body 7 is installed, the upper guide rail 27 and the lower guide rail 26 are locked, and the speaker base body 7 can perform linear motion and rotation at its upper end. The lower guide rail 26 and the upper guide rail 27 are fixedly installed with an arc guide rail 28 on the side away from the side panel 21 to facilitate the continued loading of other speaker base bodies 7 and facilitate use.

[0033] When the first speaker base body 7 slides to the position of the welding head 82, the welding head 82 can weld the speaker base body 7. A discharge port 29 is opened on the side panel 21. The discharge port 29 is relatively large. After welding, the speaker base body 7 can continue to slide away from the guide rail and be discharged from the discharge port 29, which is convenient for the next process.

[0034] Example 2: Please refer to Figure 2-Figure 6A connecting mechanism 3 is provided on one side of the supporting mechanism 2, and the connecting mechanism 3 includes a fixing rod 31 fixedly installed on the wall of the first guide groove 13, a lower supporting rod 32 is fixedly installed on the lower end of the fixing rod 31, and the lower supporting rod 32 is also overlapped and installed on the bottom wall of the first guide groove 13, an upper supporting rod 33 is slidably installed on the upper end of the fixing rod 31, and a second guide groove 35 is opened on the bottom wall of the upper supporting rod 33.

[0035] A mounting mechanism 4 is provided on one side of the connecting mechanism 3 . The mounting mechanism 4 includes a slide rod 41 slidably connected to the upper support rod 33 . A slide block 42 is fixedly mounted on one end of the slide rod 41 . The lower end of the slide block 42 is slidably mounted in the second guide groove 35 .

[0036] The interior of the upper support rod 33 is a hollow structure, and the fixed rod 31 is slidably installed in this hollow structure. The fixed rod 31, the lower support rod 32, and the upper support rod 33 are combined into a C-shaped structure. The upper support rod 33 can be adjusted up and down under the action of the fixed rod 31, so as to adapt to the speaker base body 7 of different heights and ensure that the upper guide rail 27 can always be overlapped on the upper end of the speaker base body 7.

[0037] The device is provided with a plurality of connecting mechanisms 3 and mounting mechanisms 4. A first connecting rod 34 is fixedly mounted on one end of the lower support rod 32, and the first connecting rod 34 is fixedly connected to the lower guide rail 26. A second connecting rod 43 is fixedly mounted on the side of the slide rod 41 away from the slide block 42, and the second connecting rod 43 is fixedly connected to the upper guide rail 27. The lower guide rail 26 and the upper guide rail 27 are connected respectively by the first connecting rod 34 and the second connecting rod 43, thereby ensuring the stability of the lower guide rail 26 and the upper guide rail 27.

[0038] The operator first places the speaker base body 7 from top to bottom between the two lower guide rails 26 and the two upper guide rails 27, and manually presses the speaker base body 7 downward, and the upper end side wall of the speaker base body 7 presses the upper guide rails 27 outward. When the opening between the two upper guide rails 27 gradually becomes larger, the fixed rod 31 and the lower support rod 32 remain in position, and the second connecting rod 43, the sliding rod 41, and the sliding block 42 move along the second guide groove 35 in the upper support rod 33. The outer periphery of the sliding rod 41 is provided with a first elastic member 44, and the first elastic member 44 can be any spring, bellows, etc. The component has an elastic structure, and both ends of the first elastic member 44 are fixedly connected to the sliding block 42 and the inner wall of the upper support rod 33 respectively. The sliding block 42 squeezes the first elastic member 44 during the movement. When the upper end of the speaker base body 7 is completely lower than the upper guide rail 27, the second connecting rod 43, the sliding rod 41, and the sliding block 42 lose the squeezing force and are reset under the action of the first elastic member 44, so that the upper guide rail 27 is clamped on the upper end of the speaker base body 7. The upper guide rail 27 can be reset without manual operation, and the process of pulling it out and resetting it can be done in one go, which is easy to use.

[0039] Example 3: Please refer to Figure 2-Figure 8 A linkage mechanism 6 is also provided on one side of the connection mechanism 3 , and the linkage mechanism 6 includes a push plate 61 , a third guide groove 62 is opened in the middle of the push plate 61 , and a stabilizing rod 63 is installed in the middle of the third guide groove 62 .

[0040] An extension plate 64 is fixedly installed on the upper end of the push plate 61, and the upper end of the extension plate 64 is fixedly connected to the sliding block 42. Rotating plates 65 are rotatably installed on the upper and lower ends of the push plate 61, and the two rotating plates 65 are rotatably connected to the lower support rod 32 and the upper support rod 33 respectively.

[0041] During the outward movement of the upper guide rail 27, the second connecting rod 43, the sliding rod 41, and the sliding block 42 move along the second guide groove 35 in the upper support rod 33. Under the action of the extension plate 64, the pushing plate 61 and the rotating plate 65 move outward synchronously. The diameter of the speaker base body 7 is relatively large. When the upper end of the speaker base body 7 is completely lower than the upper guide rail 27, the pushing plate 61 and the rotating plate 65 move outward, adapting to the upper diameter length of the speaker base body 7, and having a multi-point support effect.

[0042] A telescopic mechanism 5 is provided on one side of the connecting mechanism 3, and the telescopic mechanism 5 includes a first support rod 51 and a second support rod 52. One end of the first support rod 51 and the second support rod 52 are rotatably connected to the fixed rod 31 and the upper support rod 33 respectively. A moving block 53 is rotatably installed at one end of the first support rod 51 and the second support rod 52 away from the fixed rod 31, and a second elastic member 54 is installed between the two moving blocks 53. The moving block 53 is slidably installed on the stabilizing rod 63, and the second elastic member 54 is arranged on the outer periphery of the stabilizing rod 63.

[0043] During the outward movement of the pushing plate 61 and the rotating plate 65, the angle between the first support rod 51 and the second support rod 52 changes, driving the upper support rod 33 to move downward on the fixing rod 31, that is, the second connecting rod 43, the sliding rod 41, the sliding block 42, and the upper guide rail 27 move downward and are applied to the upper end of the speaker base body 7, further ensuring the fixity of the speaker base body 7.

[0044] When fixing the speaker base body 7 whose height is less than the distance between the lower guide rail 26 and the upper guide rail 27, the operator places it between the lower guide rail 26 and the upper guide rail 27, first ensuring that the lower end of the speaker base body 7 is compatible with the lower guide rail 26. As the speaker base body 7 is pushed in, its outer periphery pushes the push plate 61 and the rotating plate 65 outward, and the upper guide rail 27 synchronously moves downward and rests on the speaker base body 7, further increasing the adaptation range of the device and achieving a good fixing effect.
