Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, specifically a lifting device for loudspeaker production. Background Technology

[0002] PA (Public Address) loudspeakers are large loudspeakers used in public places. In order to ensure that the sound can be heard by the most people, PA loudspeakers are designed with a focus on increasing the volume and being able to clearly transmit the sound over long distances, thus they are characterized by their large size and weight.

[0003] Due to their large size and weight, PA speakers cannot be integrated into standard speaker production lines and can only be handled manually. However, manually handling these large and heavy PA speakers results in a heavy workload, low production efficiency, and makes it difficult to handle them gently, easily leading to collisions and damage.

[0004] To address the aforementioned problems, existing technologies offer a solution, such as the lifting device for speaker production disclosed in patent publication number CN218223270U. The device of this application utilizes a cylinder-driven assembly to provide lifting force. A turntable is mounted via a first bearing housing, and a rotating shaft is mounted via a second bearing housing. This ensures that when lifting a speaker placed on the turntable, most of the vertical weight is distributed between the two bearing housings, with only a small portion acting on the motor. Therefore, it can provide a sufficiently large lifting force without damaging the motor. During speaker assembly, it can easily lift and rotate the speaker to complete tasks such as dispensing glue, achieving automation by replacing manual labor. It also solves the problem of the motor shaft not being able to withstand excessive force. While existing devices can lift heavier speakers, they are prone to wobbling during operation, which can cause the speaker to wobble as well, reducing its stability. This further increases the risk when the speaker is raised to a certain height.

[0005] Therefore, a lifting device for loudspeaker production is proposed. Utility Model Content

[0022] Reference Figures 1 to 4 A lifting device for loudspeaker production includes a base 1, a dual-axis motor 2, a drive mechanism 3, a support platform 4, a drive rack 5, a connecting mechanism 6, a connecting block 7, and a clamping plate 8.

When the support is rising and falling, the drive rack 5 controls the connecting mechanism 6 to run. The connecting block 7 controls the clamping plate 8 to move towards the loudspeaker and clamp it.

[0023] As one embodiment of this utility model, refer to Figures 2 to 4The drive mechanism 3 includes a rotating shaft 31, a main bevel gear 32, a secondary bevel gear 33, a forward and reverse lead screw 34, a threaded block 35, a hinged telescopic frame 36, a guide block 37, and a guide rod 38. The rotating shaft 31 is connected to the dual-axis motor 2. The main bevel gear 32 is connected to the rotating shaft 31. The secondary bevel gear 33 meshes with the main bevel gear 32. The forward and reverse lead screw 34 is connected to the main bevel gear 32. The threaded block 35 is connected to the forward and reverse lead screw 34. The hinged telescopic frame 36 is connected to the threaded block 35. The guide block 37 is connected to the hinged telescopic frame 36. The guide rod 38 is connected to the guide block 37. The gear ratios of the main bevel gear 32 and the secondary bevel gear 33 are the same. The above configuration ensures that the rotation of the main bevel gear 32 and the secondary bevel gear 33 is consistent. The center line of the main bevel gear 32 is parallel to that of the positive and negative lead screws 34. This configuration also ensures that the movement paths of the two threaded blocks 35 are consistent. The base 1 has a threaded groove 39 inside, and the support platform 4 has a guide groove 310 inside.
