Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing equipment technology, and in particular to a rotating clamp for a loudspeaker painting device. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. The loudspeaker housing primarily protects the internal components. To improve the lifespan and aesthetics of the loudspeaker housing, it is typically painted. Currently, painting is usually done manually. To ensure even paint application, the housing needs to be rotated. However, manual rotation is prone to uneven speed and is inefficient. Furthermore, common painting fixtures place the loudspeaker housing on a fixed base, which is then rotated by a motor. This method inevitably results in some paint spreading into the air and falling onto the motor, significantly reducing its lifespan and potentially causing accidents. Therefore, a new type of rotating device for painting is needed. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a rotating device for speaker painting equipment that ensures uniform coating of paint onto the speaker housing, improves painting efficiency, and reduces equipment failure rate.

[0004] The technical solution of this utility model is as follows: A rotating device for a loudspeaker painting apparatus includes a base, a transmission device connected to the base, a plurality of rotating clamps connected to the transmission device, and a controller. The transmission device includes a first fixed frame connected to the base, a transmission chain plate movably connected to the first fixed frame, a drive motor for driving the transmission chain plate, a second fixed frame connected to the base, and a plurality of protruding teeth fixedly connected to the second fixed frame. The rotating clamps include a connecting base fixedly connected to the transmission chain plate, a gear shaft movably connected to the connecting base, a fixed base fixedly connected to the gear shaft, and a limiting block fixedly connected to the fixed base. When the drive motor drives the transmission chain plate to move a certain distance, the gear shaft can mesh with the protruding teeth on the fixed frame. The limiting block is adapted to the shape and size of the horn opening on the loudspeaker housing to be painted. The controller is electrically connected to the drive motor.

[0005] Using the above technical solution, when painting is required, the operator first places the speaker housing to be processed on the limiting block on the fixed base, thus fixing the relative position of the speaker housing and the fixed base. At the same time, the painting device is placed at the position corresponding to the tooth, and the painting direction of the painting device is adjusted to align with the movement path of the speaker housing. Then, the controller controls the drive motor to drive the transmission chain plate to move. When the connecting base moves with the transmission chain plate to the position of the tooth, since the gear shaft is movably connected to the connecting base and can mesh with the tooth, when the connecting base passes the position of the tooth, the tooth will drive the gear shaft to rotate, thereby driving the fixed base connected to the gear shaft and the speaker housing connected to the fixed base to rotate. This eliminates the need for the operator to manually adjust the position of the speaker housing to be processed, thus greatly improving the painting efficiency and ensuring that the paint can be sprayed evenly on the speaker housing. In addition, compared with the traditional method of the motor directly driving the fixture to rotate, the paint is less likely to enter the drive motor, thus ensuring the stable operation of the equipment. A further feature of this invention is that the limiting block is provided with a rubber sleeve, the outer surface shape of which is adapted to the shape and size of the horn opening on the speaker housing to be painted. By employing the above technical solution, the rubber sleeve on the limiting block increases the friction between the limiting block and the speaker housing placed on it, thereby further ensuring the relative positional stability between the speaker housing and the fixed base, preventing relative sliding, and thus improving the painting effect on the speaker housing.

[0006] A further feature of this invention is that the surface of the rubber sleeve is provided with a plurality of protrusions, the thickness of the protrusions is 0.5 cm, and the protrusions are made of rubber.

[0007] By adopting the above technical solution, since the surface of the rubber sleeve is provided with several protrusions, the friction between the limiting block and the speaker housing placed on the limiting block can be further improved, thereby further improving the relative positional stability between the speaker housing and the fixed base and improving the painting effect on the speaker housing.

[0008] A further feature of this invention is that a reinforcing rod is provided between the fixed base and the connecting base, the central axis of the reinforcing rod is at a certain angle to the central axis of the gear shaft, and the reinforcing rod is located on the side away from the protruding tooth.

[0009] By adopting the above technical solution, since there is a reinforcing rod between the fixed base and the connecting base, and the reinforcing rod is located on the side away from the protruding teeth, the relative positional stability of the fixed base and the connecting base can be improved, thereby avoiding the paint not being evenly sprayed on the speaker housing due to the vibration force generated during the operation of the equipment.

Detailed Implementation

[0013] like Figure 1-2As shown, a rotating device for a loudspeaker painting apparatus includes a base 1, a transmission device 2 connected to the base 1, a plurality of rotating clamps 3 connected to the transmission device 2, and a controller 4. The transmission device 2 includes a first fixed frame 5 connected to the base 1, a transmission chain plate 6 movably connected to the first fixed frame 5, a drive motor 7 for driving the transmission chain plate 6, a second fixed frame 8 connected to the base 1, and a plurality of protruding teeth 9 fixedly connected to the second fixed frame 8. The rotating clamps 3 include a connecting base 10 fixedly connected to the transmission chain plate 6, a gear shaft 11 movably connected to the connecting base 10, a fixed base 12 fixedly connected to the gear shaft 11, and a limiting block 13 fixedly connected to the fixed base 12. When the drive motor 7 drives the transmission chain plate 6 to move a certain distance, the gear shaft 11 can mesh with the protruding teeth 9 on the fixed frame. The limiting block 13 is adapted to the shape and size of the horn opening on the loudspeaker housing to be painted. The controller 4 is electrically connected to the drive motor 7. When painting is required, the operator first places the speaker housing to be processed on the limiting block 13 on the fixed base 12, thus fixing the relative position of the speaker housing and the fixed base 12. Simultaneously, the painting device is placed at the position corresponding to the tooth 9, and the painting direction of the device is adjusted to align with the movement path of the speaker housing. Then, the controller 4 controls the drive motor 7 to move the transmission chain plate 6. When the connecting base 10 moves with the transmission chain plate 6 to the position of the tooth 9, the gear shaft 11 is movably connected to the connecting base 10, and the tooth... The axle 11 can mesh with the tooth 9. Therefore, when the connecting base 10 passes the position of the tooth 9, the tooth 9 will drive the gear shaft 11 to rotate, thereby driving the fixed base 12 connected to the gear shaft 11 and the speaker housing connected to the fixed base 12 to rotate. This eliminates the need for workers to manually adjust the position of the speaker housing to be processed, thus greatly improving the painting efficiency and ensuring that the paint can be sprayed evenly on the speaker housing. In addition, compared with the traditional method of the motor directly driving the fixture to rotate, the paint is less likely to enter the drive motor 7, thus ensuring that the equipment can operate stably.

[0014] The limiting block 13 is provided with a rubber sleeve 14, and the outer surface shape of the rubber sleeve 14 is adapted to the shape and size of the horn opening on the speaker housing to be painted.

[0015] Since the limiting block 13 is provided with a rubber sleeve 14, the friction between the limiting block 13 and the speaker housing placed on the limiting block 13 can be increased, thereby further ensuring the relative position stability between the speaker housing and the fixed base 12, avoiding the phenomenon of relative sliding between the two, and thus improving the painting effect on the speaker housing.

[0016] The surface of the rubber sleeve 14 is provided with a plurality of protrusions 15, the thickness of the protrusions 15 is 0.5 cm, and the protrusions 15 are made of rubber.

[0017] Since the surface of the rubber sleeve 14 is provided with several protrusions 15, the friction between the limiting block 13 and the speaker housing placed on the limiting block 13 can be further improved, thereby further improving the relative positional stability between the speaker housing and the fixed base 12 and improving the painting effect on the speaker housing.

[0018] A reinforcing rod 16 is provided between the fixed base 12 and the connecting base 10. The central axis of the reinforcing rod 16 is at a certain angle to the central axis of the gear shaft 11. The reinforcing rod 16 is located on the side away from the convex tooth 9.

[0019] Since a reinforcing rod 16 is provided between the fixed base 12 and the connecting base 10, and the reinforcing rod 16 is located on the side away from the protrusion 9, the relative positional stability of the fixed base 12 and the connecting base 10 can be improved, thereby avoiding the paint from not being evenly sprayed on the speaker housing due to the vibration force generated during the operation of the equipment.
