Multi-layer sliding rail composite motion mechanism and application thereof

Abstract

The invention belongs to the technical field of acoustic testing equipment, and discloses a multi-layer sliding rail composite motion mechanism and application thereof. The multi-layer sliding rail composite motion mechanism comprises a motion module, and the motion module comprises a carrier plate module, an upper-layer sliding rail module and a lower-layer sliding rail module. The carrier plate module is connected to the upper-layer sliding rail module in a sliding mode, and the upper-layer sliding rail module is connected to the lower-layer sliding rail module in a sliding mode. The multi-layer sliding rail composite motion mechanism is placed in an inner cavity of the soundproof box and used for conveying a test product to enter and exit from the soundproof box for testing and can also be used for feeding and discharging conveying of a machine table on a production line. By adopting the multi-layer sliding rail composite motion mechanism, the bidirectional motion position requirements of conveying a test product out of the soundproof box and conveying the test product to the center of the soundproof box can be met at the same time, the volume of an inner cavity of the soundproof box is reduced, the cost is saved, and stable, smooth, sensitive and reliable operation can be ensured.

Description

technical field [0001] The invention belongs to the technical field of acoustic testing equipment, and in particular relates to a compound motion mechanism of multi-layer slide rails and its application. Background technique [0002] As people's requirements for the acoustic function of speaker electronic products are getting higher and higher, the acoustic function test of speaker electronic products usually needs to be carried out in a soundproof box after the production is completed. During the test, the product to be tested needs to be placed in the center of the soundproof box to ensure that the sound is attenuated as uniformly as possible in all directions, so as to avoid the sound reflection that is particularly close to the inner wall of a certain side of the soundproof box and cause interference to the test. . [0003] At present, due to the size of the inner cavity of the soundproof box, after the test is completed, the product to be tested cannot be transported t...

Problems solved by technology

[0003] At present, due to the size of the inner cavity of the soundproof box, after the test is completed, the product to be tested cannot be transported outside the soundproof box with a single-layer motion slide rail, and the During the test, the product to be tested cannot be transported to the center of the soundproof box. If the inner cavity volume of the soundproof box is increased and the moving slide rail is lengthened, it can meet the requirements of transporting the product to be tested outside the soundproof box or transporting the product to be tested to The demand for the center position of the soundproof box, however, is limited by the structural volume of the soundproof box and the sliding module itself, and it is impossible to meet the requirements of transporting the product to be tested to the center of the soundproof box and transporting the product to be tested at the same time during the test Two-way movement requirements to the outside of the soundproof box; at the same time, increasing the inner cavity volume of the soundproof box and lengthening the motion slide rail will also lead to a sharp increase in manufacturing costs
