Description

Technical Field

[0001] The present invention relates to the technical field of linear multi-axis transmission, and more specifically to a linear motion platform. Background Art

[0002] After electronic products are manufactured, they will undergo quality inspection and functional testing to ensure the final product quality. According to the product design specifications, different touch points of the electronic products will be triggered to determine whether the main functions of the product can be performed normally.

[0003] However, during the test process, the touch site distribution density and the size of the touch sites of different electronic products are different. The touch sites of some electronic products are relatively dense and the touch sites are small in size. When the touch heads of general testing organizations are testing such electronic products with dense touch sites, they cannot test the dense test points at the same time (a single touch head may contact multiple touch sites when pressed down). In order to ensure the accuracy of the detection results of each touch site, it is necessary to test each single test point one by one, but this operation results in low inspection efficiency and cannot meet customer needs.
