Description

Technical Field

[0001] This utility model relates to the technical field of automatic locking and bending machine for speaker mesh, and in particular to an automatic locking and bending machine for speaker mesh. Background Technology

[0002] The automatic locking and bending machine for speaker grilles is an automated device specifically designed for processing speaker grilles. It is primarily used for processing speaker grilles, particularly for bending the metal clips on the grilles to secure the plastic product to the grille. The emergence of the automatic locking and bending machine for speaker grilles provides the speaker manufacturing industry with a more efficient and precise processing method. The speaker grille is typically flat before bending to facilitate processing and transportation.

[0003] The existing automatic locking and bending machine for horn mesh has certain drawbacks. The operating table of the traditional automatic locking and bending machine for horn mesh has no protective structure. If the horn mesh is not placed in the correct position and the operator is in a hurry to change it, the stamping structure can easily crush the operator's fingers. In addition, the unprocessed horn mesh is placed on the ground storage basket and on the operating table surface, which requires frequent squatting and standing to pick it up and occupies the operating table surface, making it inconvenient to pick up the horn mesh and affecting the operator's operation.

The lifting protective baffle 3 can automatically lift and lower the protective baffle, which not only provides protection but also does not affect the operator's operation. This makes the automatic locking bending machine of the speaker mesh safer and avoids the operator's fingers being pressed by the stamping mechanism 2 due to the speaker mesh being placed incorrectly. The speaker mesh storage cabinet 6 allows the speaker mesh before processing to be neatly stacked and stored, making it more convenient to take out the unprocessed speaker mesh. The operation method is simpler, as it does not need to be placed on the operating table surface or frequently squatted up and down to take out the speaker mesh.

[0026] In this embodiment, the lifting protective baffle 3 includes a motor outer frame 301, an internal hex screw 302, a first motor 303, a limit ring 304, a screw 305, an internal threaded short sleeve 306, and a transparent protective plate 307.

[0027] In this embodiment, the hex socket screws 302 are located in the through holes at the four corners of the motor outer frame 301. The motor outer frame 301 is fixedly installed on the upper surface inside the bending machine body 1 by the hex socket screws 302. The first motor 303 is fixedly installed inside the motor outer frame 301. The limiting ring 304 is fixedly installed in the groove hole inside the bending machine body 1.

[0028] In this embodiment, the screw 305 is fixedly connected to the lower end of the rotating shaft of the first motor 303. The lower end of the screw 305 is inserted into the inside of the limiting ring 304. The internal threaded short sleeve 306 is sleeved on the outside of the screw 305 at the threaded position. The transparent protective plate 307 is fixedly connected between the internal threaded short sleeves 306. The transparent protective plate 307 is located in front of the stamping mechanism 2.

[0029] In this embodiment, the speaker mesh storage cabinet 6 includes a transparent box 601, an extrusion plate 602, a threaded hole strip 603, a screw turntable 604, a retrieval through hole 605, a discharge through hole 606, a U-shaped frame 607, a second motor 608, a rotating wheel 609, a sponge sleeve 610, and a rubber sleeve 611.

[0030] In this embodiment, the transparent box 601 is fixedly installed on the front surface of the bending machine body 1 near the lower corner. The extrusion plate 602 is located in the groove inside the transparent box 601. The threaded hole strip 603 is fixedly installed on the middle of one side of the transparent box 601. The screw turntable 604 is located inside the threaded hole strip 603. The front end of the screw turntable 604 is inserted into the groove hole on the rear surface of the extrusion plate 602.

[0031] In this embodiment, the access hole 605 is located on the front surface of the transparent box 601 near the lower corner, the discharge hole 606 is located on the front surface of the transparent box 601 near the lower end, the U-shaped frame 607 is fixedly installed on the lower surface of the transparent box 601 near the front end of the access hole 605, the second motor 608 is fixedly installed on one side of the U-shaped frame 607, the two ends of the rotating wheel 609 are inserted into the groove holes on the inner side of the U-shaped frame 607, the sponge sleeve 610 is fixedly installed on the outer side of the rotating wheel 609, the rubber sleeve 611 is fixedly installed on the outer side of the sponge sleeve 610, the outer side of the rubber sleeve 611 has a transverse groove, and the upper end of the rubber sleeve 611 is located inside the access hole 605.

[0032] It should be noted that this utility model is an automatic locking and bending machine for speaker grilles. In use, the machine is driven by the casters 4. The stacked speaker grilles are placed inside the transparent box 601 in the speaker grille storage cabinet 6. The screw turntable 604 inside the threaded plate 603 is rotated, pushing the extrusion plate 602 inside the transparent box 601, keeping the speaker grilles neat. The surface of the rubber sleeve 611 adheres to the lower surface of the bottommost speaker grille. When the speaker grille is to be retrieved, the second motor 608 drives the rotating wheel 609 to rotate, pulling the speaker grille out through the discharge hole 606. The sponge sleeve 610 makes the rubber sleeve 611 fit more closely to the lower surface of the speaker grille. The operator pulls out the speaker grille through the retrieval hole 605. The speaker grille storage cabinet 6 allows the speaker grilles before processing to be neatly stacked and stored. Retrieving unprocessed speaker grilles is more convenient and simpler. It eliminates the need to place them on the workbench or frequently squat and stand to retrieve them. In the lifting protective baffle 3, motor 303 drives screw 305 to rotate, causing the internal threaded short sleeve 306 to rise and fall along screw 305. The transparent protective plate 307 rises and falls accordingly. During this process, the lower end of screw 305 rotates within the limiting ring 304, and the transparent protective plate 307 is inserted into the groove hole inside the bending machine body 1. The speaker grille is placed into the stamping die of the stamping mechanism 2. The lifting protective baffle 3 can automatically raise and lower the protective plate, providing protection without affecting the operator's work. This makes the automatic locking of the speaker grille in the bending machine safer, preventing the operator from accidentally pressing their fingers on the stamping mechanism 2 if the speaker grille is not placed correctly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
