[0050] See also Figures 1 to 8 This embodiment provides a device for extracting a loudspeaker coil support 81 , including a frame 10 and two clamping mechanisms 20 .

[0051] The frame 10 can be arranged on the production line for horizontal and vertical movement, and the frame 10 can be connected to a robot to realize its horizontal and vertical movement. Two clamping mechanisms 20 are arranged on the frame 10 symmetrically, and the two clamping mechanisms 20 are used to clamp the bracket 81 from both sides.

[0052] The clamping mechanism 20 includes a first mounting seat 30 , a second mounting seat 40 , a sliding block 50 , a clamping head 60 and a driving mechanism.

[0053] The first mounting seat 30 is connected to the frame 10. The second mounting seat 40 is slidably mounted in the first mounting seat 30. One end of the sliding block 50 is slidably mounted in the second mounting seat 40, and the sliding block 50 can remain motionless on the second mounting seat 40. The clamping head 60 is connected to the end of the sliding block 50 and can be abutted against the first mounting seat 30. The clamping head 60 is provided with a clamping opening 61 that fits with the end of the bracket 81, and the clamping head 60 supports the bracket 81 through the clamping opening 61. The driving mechanism is used to drive the second mounting seat 40 to slide. Specifically, both ends of the bracket 81 are plate-shaped and can be inserted into the clamping opening 61 on the same side.

[0054] In this embodiment, the support plate 80 is transported to the bottom of the two clamping mechanisms 20 through the assembly line. When the two clamping mechanisms 20 move down, the support plate 80 is located between the two clamping mechanisms 20. Driven by the driving mechanism, the second mounting seats 40 of the two clamping mechanisms 20 slide close to each other. At this time, the second mounting seat 40 drives the sliding block 50 to connect the clamping head 60 at the end of the sliding block 50 to approach the bracket 81 on the middle support plate 80. The shape of the clamping opening 61 on the clamping head 60 fits the end of the bracket 81, so that the two clamping heads 60 clamp the two ends of the bracket 81. Then the frame 10 rises, driving the two clamping mechanisms 20 to rise, so that the bracket 81 is pulled off the support plate 80. When the second mounting seat 40 retreats under the drive of the driving mechanism, it drives the sliding block 50 and the clamping head 60 to retreat, and the bracket 81 falls from between the two clamping heads 60.

[0055] Normally, the sliding block 50 remains relatively stationary in the second mounting seat 40. Once the size of the bracket 81 increases, the two clamping heads 60 abut against the two ends of the bracket 81, and the sliding block 50 slides toward the inside of the second mounting seat 40 to make way, so that the clamping mechanism 20 can adapt to the larger bracket 81. When the sliding block 50 drives the clamping head 60 to retreat a certain distance, the clamping head 60 abuts against the first mounting seat 30, and the second mounting seat 40 continues to be driven back by the driving mechanism, and the sliding block 50 slides out of the second mounting seat 40 to reset.

[0056] In one embodiment, the second mounting seat 40 has a second mounting hole 41 that runs through in the transverse direction, and the sliding block 50 is slidably mounted in the second mounting hole 41 in the transverse direction. The inner walls of both sides of the second mounting hole 41 are respectively provided with elastically extending locking rods 42, and the ends of the locking rods 42 elastically abut against the corresponding outer walls of the sliding block 50. Specifically, the second mounting seat 40 is a rectangular block, and the second mounting hole 41 is a rectangular hole with open ends. In addition, the ends of the locking rods 42 that abut against the outer wall of the sliding block 50 are ball-shaped.

[0057] In this embodiment, the locking rod 42 applies a certain external force to the sliding block 50, so that when the second mounting seat 40 moves under the drive of the driving mechanism, the sliding block 50 moves with the second driving block, so that the clamping head 60 connected to the sliding block 50 can be close to or away from the bracket 81, thereby clamping and releasing the bracket 81. When the size of the bracket 81 becomes larger, after the two clamping heads 60 approach each other and abut against the bracket 81, the sliding block 50 can also slide relative to the end of the locking rod 42 to give way, until the subsequent sliding block 50 retreats, the clamping head 60 abuts against the first mounting seat 30, and the sliding block 50 and the second mounting seat 40 are reset.

[0058] In one embodiment, locking sleeves 43 are respectively connected to both sides of the second mounting hole 41, and a locking spring 44 is arranged in each locking sleeve 43. A limiting ring 45 that shrinks inward is provided at an end portion of the locking sleeve 43 away from the inner wall of the second mounting hole 41. One end of the locking rod 42 passes through the corresponding limiting ring 45 and is connected to a stopper 46. One end of the stopper 46 abuts against the locking spring 44, and the other end of the stopper 46 abuts against the limiting ring 45.

[0059] In this embodiment, under the action of the locking spring 44 , the end of the locking rod 42 faces and elastically abuts against the outer side wall of the sliding block 50 .

[0060] In one embodiment, the outer wall of the sliding block 50 abutting against the locking rod 42 is corrugated along the sliding direction thereof.

[0061] In this embodiment, the side wall of the sliding block 50 is corrugated so that the positions of the sliding block 50 and the locking rod 42 remain relatively stable, so that when the second mounting seat 40 moves, the sliding block 50 can be stably driven to move.

[0062] In one embodiment, the first mounting seat 30 has a first mounting hole 31 penetrating along the sliding direction of the sliding block 50. The first mounting seat 30 is provided with a clearance opening 32 extending along the sliding direction of the sliding block 50.

[0063] The driving mechanism includes a third mounting seat 70 , a connecting rod 72 and an electric push rod 73 .

[0064] The third mounting seat 70 is slidably mounted in the first mounting seat 30, and the third mounting seat 70 has a third mounting hole 71 that penetrates along the sliding direction of the sliding block 50. One end of the connecting rod 72 is connected to the upper end of the third mounting seat 70, and the other end of the connecting rod 72 is located outside the first mounting seat 30 after passing through the clearance opening 32. The electric push rod 73 is arranged on the first mounting seat 30, and its output end is connected to the end of the connecting rod 72 away from the third mounting seat 70. The second mounting seat 40 is mounted in the third mounting hole 71. Specifically, the third mounting seat 70 is a rectangular parallelepiped, and is slidably mounted in the first mounting hole 31 by means of a guide rail, the second mounting seat 40 is slidably mounted in the third mounting hole 71 by means of a guide rail, and the sliding block 50 is slidably mounted in the second mounting hole 41 by means of a guide rail. From the outside to the inside, they are: the first mounting seat 30, the third mounting seat 70, the second mounting seat 40 and the sliding block 50, and the sliding directions of the third mounting seat 70, the second mounting seat 40 and the sliding block 50 are the same.

[0065] In this embodiment, the electric push rod 73 pushes the connecting rod 72 outside the first mounting seat 30, thereby driving the third mounting seat 70 to slide in the first mounting hole 31, and further driving the second mounting seat 40 to move.

[0066] In one embodiment, installation windows 74 are respectively provided on both sides of the third mounting seat 70, and a rotatable gear 75 is provided in each installation window 74; first racks 47 are respectively provided on both sides of the second mounting seat 40, and the first racks 47 are meshed with the corresponding gears 75; second racks 33 are respectively provided on the inner wall of the first mounting hole 31 corresponding to the installation windows 74, and the second racks 33 are meshed with the corresponding gears 75.

[0067] In this embodiment, a gear 75 meshes with the first rack 47 and the second rack 33 at the same time. When the third mounting seat 70 is driven by the electric push rod 73 and then slides in the first mounting hole 31, the gear 75 rotates under the meshing of the second rack 33, thereby driving the second mounting seat 40 to slide in the third mounting hole 71, and the sliding directions of the second mounting seat 40 and the third mounting seat 70 are the same, so that when the stroke of the electric push rod 73 remains unchanged, the sliding distance of the third mounting seat 70 is S1, and the sliding distance of the second mounting seat 40 together with the sliding block 50 and the clamping head 60 thereon is S2, and S2 is greater than S1, so that a larger size of the bracket 81 can be adapted. In addition, when the bracket 81 is replaced on the assembly line, the extraction device does not need to adjust the parameters additionally, thereby improving the applicability.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
