[0039] like Figures 1-2 As shown, the speaker bending device in this embodiment is designed for a strip 2000 composed of rows of speaker components 1000, which is integrally formed by injection molding equipment. This strip 2000 has a material edge 3000, on which a plurality of material holes 3010 are provided, and the height of the material edge 3000 is higher than the overall height of the strip 2000, forming a Z-shaped structure.

[0040] Combination Figures 3-5As shown, the speaker bending device in this embodiment mainly includes a support unit 10 and a guide unit 20, a feeding unit 30, a cutting unit 40, a conveying unit 50, and a breaking unit 60 arranged sequentially on the support unit 10. The guide unit 20 can be connected to the injection molding equipment to guide the material strip 2000. Then, the feeding unit 30 feeds the material in a step-by-step manner, that is, it moves the distance of one speaker component at a time, and sends it to the cutting unit 40 for cutting. The connecting handle between two adjacent speaker components is cut off, or a single speaker component is cut off.

[0041] The material guiding unit 20 includes a material guiding rod 21 and a material guiding plate 22. The material guiding rod 21 and the material guiding plate 22 are used to carry the material belt 2000.

The first feeding cylinder 32 and the feeding frame 33 are mounted on the feeding track 31, and the second feeding cylinder 35 is mounted on the feeding frame 33. The second feeding cylinder 35 is used to drive the positioning post 34 to pass into the material hole 3010 of the material edge 3000 located inside the feeding track 31. The first feeding cylinder 32 is used to push the feeding frame 33 to drive the material belt 2000 to be conveyed forward along the feeding track 31.

[0044] The feeding track 31 is provided with a first channel 311 and a second channel 312 that are connected. The second channel 312 is higher than the first channel 311. The first channel 311 is used to feed the material belt 2000 through, and the second channel 312 is used to feed the material edge 3000 through.

[0048] Combination Figures 9-10 As shown, the conveying unit 50 includes a first translation component, a first conveying frame 51, a first conveying cylinder 52, a first adsorption component 53, a second conveying cylinder 54, and a second adsorption component 55. The first translation component is used to drive the first conveying cylinder 52 to make horizontal reciprocating motion. The first conveying cylinder 52 is used to drive the first conveying frame 51 to make lifting motion. The second conveying cylinder 54 is disposed on the first conveying frame 51 and is used to drive the second adsorption component 55 to make lifting motion. The first adsorption component 53 is disposed below the first conveying frame 51.

[0049] The first translation component includes a support frame 56, a drive cylinder 57, and a slide plate 58. The support frame 56 is mounted on the support unit 10, and the slide plate 58 is slidably mounted on the support frame 56.

[0050] The output end of the second transport cylinder 54 is connected to the connecting frame 59. The connecting frame 59 extends below the first transport frame 51 and is connected to the second adsorption component 55. Both the first adsorption component 53 and the second adsorption component 55 include adsorption heads for vacuum adsorption. The end of the adsorption head matches the shape of the speaker component 1000.

[0051] Combination Figures 11-12 As shown, the breaking unit 60 includes a breaking cylinder 61 and a breaking mold 62. The breaking unit 60 is located below the conveying unit 50. The breaking cylinder 61 is used to drive the breaking mold 62 to make a lifting and lowering movement. The second adsorption component 55 is used to adsorb the speaker component 1000 from the cutting unit 40 to the breaking mold 62. The second adsorption component 55 and the breaking mold 62 make relative lifting and lowering movements and break the material handle 1010 on the speaker component 1000. The first adsorption component 53 is used to adsorb the speaker component 1000 on the breaking mold 62 to the outside for collection.

[0052] The output end of the breaking cylinder 61 is connected to the linkage frame 63. One end of the linkage frame 63 is provided with a slot 631. The breaking mold 62 is clamped in the slot 631. An installation station 621 is provided on the breaking mold 62. The installation station 621 is used to install the speaker component 1000. The installation station 621 corresponds to the positions of the first adsorption component 53 and the second adsorption component 55. A limiting plate 131 protrudes from the material discharge hole 13. The limiting plate 131 passes through the slot 631 and is located below the breaking mold 62. The limiting plate 131 restricts the further downward movement of the breaking mold 62.

[0053] Specifically, the breaking unit 60 works in conjunction with the conveying unit 50 to perform the breaking action. First, the speaker component is drawn from the end of the feeding track 31 to the top of the breaking mold 62 by the first translation component and the second adsorption component 55. The first conveying cylinder 52 drives the second adsorption component 55 to descend to the position of the breaking mold 62 to place the speaker component. At this time, the second conveying cylinder 54 and the breaking cylinder 61 work simultaneously, causing the second adsorption component 55 and the breaking mold 62 to move relative to each other multiple times, thereby breaking the material handle at the edge of the speaker component to obtain the finished product. The broken material handle is recycled into the waste recycling track 14 through the drop hole 13. Then, the second adsorption component 55 returns to its original position and repeats the above operation. At the same time, the first adsorption component 53 is located at the corresponding position of the breaking mold 62 when the second adsorption component 55 returns to its original position and adsorbs the finished product to the finished product recycling track 15 for recycling.
