DETAILED DESCRIPTION

[0056] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in further detail below with reference to the drawings.

[0058] The embodiments of the present disclosure provide a loudspeaker assembly clamp, as shown in the drawings, Figure 1 The loudspeaker assembly clamp includes a fixed plate 1, a pressing die set 2, and a sliding mechanism 3. The fixed plate 1 is used to carry a bottom shell 100 of a smart watch. The pressing die set 2 and the sliding mechanism 3 are respectively located on both sides of the fixed plate 1, and the bottom shell 100 is located between the pressing die set 2 and the fixed plate 1. The pressing die set 2 has a first state and a second state. In the first state, the pressing die set 2 and the bottom shell 100 abut, and in the second state, the pressing die set 2 and the bottom shell 100 are separated. Figure 2 As shown in the drawings, Figure 3 As shown in the drawings, Figure 4 As shown in the drawings,

[0059] The loudspeaker 200 has a waterproof ring. After the loudspeaker 200 extends into the loudspeaker slot 101, the waterproof ring fully interferes with the loudspeaker slot 101, and there is a large friction force between the waterproof ring and the loudspeaker slot 101, so that the loudspeaker is fixed in the loudspeaker slot 101.

[0060] The technical scheme provided by the embodiments of the present disclosure, when assembling the loudspeaker 200 to the bottom shell 100, first, the loudspeaker 200 is placed on the sliding mechanism 3. Then, the bottom shell 100 is placed on the fixed plate 1, and the loudspeaker slot 101 of the bottom shell 100 is opposite to the mounting hole 10. Next, the pressing die set 2 is abutted to the bottom shell 100, so that the bottom shell 100 is fixed to the fixed plate 1. Then, the sliding mechanism 3 pushes the loudspeaker 200 to move towards the loudspeaker slot 101 of the bottom shell 100 until the loudspeaker 200 is fixed in the loudspeaker slot 101. Subsequently, the sliding mechanism moves in a direction away from the loudspeaker slot 101. Finally, the pressing die set 2 and the bottom shell 100 are separated, and the bottom shell 100 is taken off from the fixed plate 1. In this way, the assembly of the bottom shell 100 and the loudspeaker 200 is completed.

[0061] In addition, compared with manual assembly, the loudspeaker assembly fixture can realize higher assembly efficiency.

[0062] In some examples, as shown in Figure 5 The fixed plate 1 is provided with a positioning piece 11, the positioning piece 11 has an opening 110 opposite to the mounting hole 10, and the loudspeaker 200 penetrates the mounting hole 10 and the opening 110. The positioning piece 11 has a positioning slot 111, and the bottom shell 100 is located in the positioning slot 111. The positioning slot 111 is designed in a profiled manner, so that the shape of the positioning slot 111 is substantially the same as that of the bottom shell 100, thereby ensuring higher positioning accuracy of the bottom shell 100.

[0063] For example, the positioning accuracy of the positioning piece 11 to the bottom shell 100 can be 0.02 mm.

[0064] In some examples, the positioning piece 11 is made of POM (Polyoxymethylene, polyoxymethylene) material, so that the positioning piece 11 has higher strength and wear resistance.

[0065] Next, the implementation of the pressing die set 2 is exemplarily described.

[0066] In some examples, as shown in Figure 6 and Figure 7 The pressing die set 2 includes a first driving mechanism 21 and a pressing block 22. The first driving mechanism 21 is fixed to the fixed plate 1, and the first driving mechanism 21 is used to drive the pressing block 22 to slide in a second direction. The second direction is the axial direction of the mounting hole 10. As shown in Figure 6 In the first state, the pressing block 22 abuts against the bottom shell 100, so as to press the bottom shell 100 tightly and avoid the bottom shell 100 from being deviated during the assembly of the loudspeaker 200. As shown in Figure 7 In the second state, the pressing block 22 is separated from the bottom shell 100, and a large gap is formed between the pressing block 22 and the fixed plate 1, so that the bottom shell 100 can be placed on the fixed plate 1 or taken off from the fixed plate 1.

[0067] In some examples, such as Figure 8 As shown, the first drive mechanism 21 includes a first cylinder 211 and a first piston rod 212. The first cylinder 211 is fixed to the fixing plate 1, and the first piston rod 212 is located inside the first cylinder 211 and slidably connected to it. The pressure block 22 is connected to the end of the first piston rod 212 away from the first cylinder 211. The first drive mechanism 21 is powered by compressed gas, and the first piston rod 212 moves in the first cylinder 211 under the action of the gas, which makes the cost of the first drive mechanism 21 low. The fixing plate 1 has a through hole, the first cylinder 211 is located on the side of the fixing plate 1 away from the positioning member 11, and the first piston rod 212 passes through the through hole.

[0068] In other examples, the first drive mechanism 21 may also be powered by a motor to drive the pressure block 22 to move. For instance, the first drive mechanism 21 includes a motor and a ball screw, the ball screw comprising a screw rod and a nut, the motor and the screw rod being driven together, the nut looping around the screw rod, and the nut being driven together with the pressure block 22. When the motor rotates, the nut moves on the screw rod, thereby causing the pressure block 22 to move in the second direction.

[0069] In some examples, the pressure block 22 and the first drive mechanism 21 are rotatably connected, and the rotation axis of the pressure block 22 is parallel to the second direction. When it is necessary to place the bottom shell 100 on the fixing plate 1 or remove the bottom shell 100 from the fixing plate 1, the pressure block 22 is rotated to avoid the bottom shell 100 colliding with the pressure block 22 when placing or removing the bottom shell 100.

[0070] In some examples, the pressure block 22 is made of aluminum alloy inside and wrapped with soft silicone on the outside. This way, it can both press the bottom shell 100 firmly and prevent scratches on the bottom shell 100.

[0071] In other examples, the clamping module 2 can also be a snap-fit, which is rotatably connected to the fixing plate 1. When the bottom shell 100 is placed on the fixing plate 1, the snap-fit ​​is flipped so that it engages above the bottom shell 100. After assembly is complete, the snap-fit ​​is flipped in the opposite direction to separate it from the bottom shell 100.

[0072] The implementation of the sliding mechanism 3 will be illustrated below.

[0073] In some examples, such as Figure 9As shown, the sliding mechanism 3 comprises a second driving mechanism 31 and a fixed block 32. The second driving mechanism 31 is configured to push the fixed block 32 to slide in the first direction, and the fixed block 32 is configured to carry the horn 200. After the horn 200 is placed on the fixed block 32, the second driving mechanism 31 pushes the fixed block 32 to move towards the horn slot 101. After the horn 200 is fixed in the horn slot 101, the second driving mechanism 31 drives the fixed block 32 to move away from the horn slot 101.

[0074] In some examples, as shown in FIG. 2, the second driving mechanism 31 comprises a second cylinder 311 and a second piston rod 312. The second cylinder 311 is fixed to the side of the fixed plate 1 away from the pressing die set 2, and the second piston rod 312 is in sliding connection with the second cylinder 311. The second piston rod 312 is configured to push the fixed block 32 to slide in the first direction. The second driving mechanism 31 is powered by compressed gas, and the second piston rod 312 moves in the second cylinder 311 under the action of the gas, so that the cost of the second driving mechanism 31 is relatively low. Figure 9 In some examples, the second cylinder 311 has an adjusting screw, which can adjust the air intake of the second cylinder 311, so as to control the moving speed of the second piston rod 312.

[0075] In other examples, the second driving mechanism 31 can drive the fixed block 32 by a motor. For example, as shown in FIG. 3, the second driving mechanism 31 comprises a base 313, a motor plate 314, a motor 315, a lead screw 316, a sliding block 317, a tail plate 318 and a push plate 319. The base 313, the motor plate 314 and the tail plate 318 are fixed to the fixed plate 1, and the motor 315 is fixed to the motor plate 314. One end of the lead screw 316 is in transmission connection with the motor 315, and the other end is in turn penetrating through the motor plate 314 and the sliding block 317, and is fixedly connected with the tail plate 318. The motor 315 drives the sliding block 317 to slide with the base 313 through the lead screw 316.

[0076] Figure 10 The push plate 319 has a first plate body 3191 and a second plate body 3192 arranged in a bent manner. The first plate body 3191 is connected with the sliding block 317, and the sliding block 317 is located between the first plate body 3191 and the base 313. The second plate body 3192 is connected with the tail plate 318, and the tail plate 318 is located between the second plate body 3192 and the sliding block 317.

[0077] When the motor 315 works, the sliding block 317 drives the push plate 319 to move, and the second plate body 3192 pushes the fixed block 32 to move, so as to push the horn 200 into the horn slot 101.

[0078]

[0079] ​​In some examples, the fixing block 32 is a metal block. Since the loudspeaker 200 itself has magnetism, the fixing block 32 is set to be a metal block, so that the loudspeaker 200 is adsorbed on the fixing block 32 by magnetic force. In this way, the loudspeaker 200 does not need to be fixed on the fixing block 32 by using other components. When the loudspeaker 200 is inserted into the loudspeaker slot 101, the friction force between the loudspeaker 200 and the loudspeaker slot 101 can overcome the magnetic force between the loudspeaker 200 and the fixing block 32. In this way, when the second driving mechanism 31 drives the fixing block 32 to move in a direction away from the loudspeaker slot 101, the loudspeaker 200 will not be separated from the loudspeaker slot 101.

[0080] For example, the material of the fixing block 32 is quenched high carbon steel.

[0081] In some examples, as shown in Figure 11 The fixing block 32 includes a fixing block body 321 and a plate body 322, and the plate body 322 passes through the mounting hole 10. The plate body 322 has a mounting slot 3220, and the loudspeaker 200 is fixed in the mounting slot 3220. The mounting slot 3220 is designed in a profiled manner, so that the shape of the mounting slot 3220 is substantially the same as the shape of the loudspeaker 200, thereby ensuring that the loudspeaker 200 has high positioning accuracy. The phenomenon of the waterproof ring of the loudspeaker 200 being turned up or burst during assembly is avoided.

[0082] For example, the thickness of the plate body 322 is 0.1mm-0.4mm, for example, the thickness of the plate body 322 can be 0.2mm.

[0083] The positions of the loudspeaker slots 101 of the bottom shells 100 of the same model are the same, so the loudspeaker assembly fixture can realize the assembly between the bottom shell 100 and the loudspeaker 200 of the same model by the above-mentioned mechanism. The positions of the loudspeaker slots 101 of the bottom shells 100 of different models can be different, so the position of the fixing block 32 needs to be adjusted to ensure that the loudspeaker 200 can be aligned with the loudspeaker slot 101. In order to make the loudspeaker assembly fixture applicable to the assembly between the bottom shell 100 and the loudspeaker 200 of different models, the sliding mechanism 3 further includes a sliding table assembly 33.

[0084] As shown in Figure 12 The sliding table assembly 33 is slidably connected with the second driving mechanism 31 in a second direction and a third direction, and the fixing block 32 is fixed to the sliding table assembly 33, wherein the second direction is the axial direction of the mounting hole 10, and the third direction is perpendicular to the second direction and the first direction. In this way, when the bottom shell 100 of a different model is replaced, the sliding table assembly 33 can adjust the position of the loudspeaker 200, so that the loudspeaker 200 is aligned with the loudspeaker slot 101.

[0085] Next, an example of the implementation of the sliding table assembly 33 is described.

[0086] In some examples, asFigure 12 and Figure 13 As shown in FIG. 3, the slide assembly 33 includes a first slide 331, a second slide 332, a third slide 333 and a fourth slide 334 arranged in sequence along the first direction. The first slide 331 is fixed to the second driving mechanism 31, the second slide 332 is slidably connected to the first slide 331 along the second direction, the third slide 333 is fixed to the second slide 332, the fourth slide 334 is slidably connected to the third slide 333 along the third direction, and the fixed block 32 is fixed to the fourth slide 334.

[0087] For example, as shown in FIG. 4, the first slide 331 has a first slide bar 3310, and the second slide 332 has a first slide groove 3320. The length direction of the first slide groove 3320 is along the second direction, and the first slide bar 3310 is slidably connected to the first slide groove 3320. Figure 14 As shown in FIG. 4, the width of the first slide groove 3320 gradually decreases along the direction close to the opening of the first slide groove 3320, and the outer wall of the first slide bar 3310 is in close contact with the inner wall of the first slide groove 3320. In this way, the first slide 331 and the second slide 332 can be limited in the first direction and the third direction.

[0088] Correspondingly, the third slide 333 has a second slide bar 3330, and the fourth slide 334 has a second slide groove 3340. The length direction of the second slide groove 3340 is along the third direction, and the second slide bar 3330 is slidably connected to the second slide groove 3340. The width of the second slide groove 3340 gradually decreases along the direction close to the opening of the second slide groove 3340, and the outer wall of the second slide bar 3330 is in close contact with the inner wall of the second slide groove 3340. In this way, the third slide 333 and the fourth slide 334 can be limited in the first direction and the second direction.

[0089] It can be understood that the first slide 331 and the third slide 333 can also have a slide groove, and the second slide 332 and the fourth slide 334 can have a slide bar.

[0090] When the loudspeaker 200 is aligned with the loudspeaker slot 101 in the second direction and the third direction, the second slide 332 and the fourth slide 334 need to be fixed. Therefore, in some examples, as shown in FIG. 5, the slide assembly 33 further includes a first clamping plate 335, a first clamping bolt 336, a second clamping plate 337 and a second clamping bolt 338. Figure 13 and Figure 14 As shown in FIG. 5, the first clamping plate 335 is fixed to the second slide 332, and the second clamping plate 337 is fixed to the fourth slide 334. The first clamping bolt 336 is screwed into the first clamping plate 335 and the second clamping plate 337, and the second clamping bolt 338 is screwed into the first clamping plate 335 and the second clamping plate 337.

[0091] The first clamping plate 335 is fixed to the first sliding table 331, and has a first sliding hole 3350 with a length direction along the second direction. The first clamping bolt 336 penetrates the first sliding hole 3350 and is threadedly connected with the second sliding table 332. When the position of the loudspeaker 200 needs to be adjusted along the second direction, the first clamping bolt 336 is loosened, and the second sliding table 332 is pushed to move. When the loudspeaker 200 is flush with the loudspeaker slot 101 along the second direction, the first clamping bolt 336 is tightened to fix the second sliding table 332.

[0092] The second clamping plate 337 is fixed to the third sliding table 333, and has a second sliding hole 3370 with a length direction along the third direction. The second clamping bolt 338 penetrates the second sliding hole 3370 and is threadedly connected with the fourth sliding table 334. When the position of the loudspeaker 200 needs to be adjusted along the third direction, the second clamping bolt 338 is loosened, and the fourth sliding table 334 is pushed to move. When the loudspeaker 200 is flush with the loudspeaker slot 101 along the third direction, the second clamping bolt 338 is tightened to fix the fourth sliding table 334.

[0093] In some examples, as shown in FIG. 4, the loudspeaker assembly fixture further comprises a box 4. The box 4 has an opening, and the fixed plate 1 is used to cover the opening. The sliding mechanism 3 is located inside the box 4. The box 4 is an electric control box, and the inside of the box 4 is used to arrange wires. Figure 15

[0094] In some examples, as shown in FIG. 4, one side of the fixed plate 1 is rotationally connected with the side wall of the box 4. When the positions of the second sliding table 332 and the fourth sliding table 334 need to be adjusted, the fixed plate 1 is rotated in a direction away from the opening of the box 4. Thus, the sliding table assembly 33 is exposed.
