Detailed Description

As shown in fig. 1 to 4, in this embodiment, the present invention includes a base 1, wherein the base 1 is provided with a mounting seat 2, a first linear slide rail 3 and a first motor screw module 4, the first linear slide rail 3 is disposed in an X direction, the first motor screw module 4 drives a moving plate 5 to slide on the first linear slide rail 3, the moving plate 5 is provided with a second linear slide rail 6 and a second motor screw module 7, the second linear slide rail 6 is disposed in a Y direction, the second motor screw module 7 drives a product carrier plate 8 to slide on the second linear slide rail 6, and the mounting seat 2 is provided with a striking mechanism 9 located above the product carrier plate 8. Compared with the defects of the traditional technology, in the utility model, during testing, a keyboard is placed on the product carrier plate 8, and the keyboard moves to the position right below the knocking mechanism 9 under the driving of the first motor lead screw module 4, the second motor lead screw module 7 and the third motor lead screw module 10 to carry out knocking test, so that the utility model has the advantages of high guiding precision, good wear resistance, long service life and simple installation and disassembly through the arrangement of the first linear slide rail 3 and the second linear slide rail 6, and simultaneously, the utility model has the following advantages due to the use of the motor lead screw modules:

1. stability: the screw rod has higher rigidity, can bear larger axial force, and has a self-locking function compared with an air cylinder, so the screw rod has higher stability in the aspect of transmission;

2. the accuracy is as follows: the positioning precision of the lead screw is high, the air cylinder is easy to be interfered by external environment to cause errors, the precision positioning precision is low, and the high-precision detection of products is not facilitated;

3. rapidity: the speed that the motor lead screw provided is very fast, is favorable to improving detection efficiency. Has self-locking performance, so the stopping property is high. And the cylinder can not be self-locked, and if the cylinder moves at a high speed, a large error can be caused.

Therefore, the motor lead screw module is adopted, translation in different directions can be achieved, the transmission speed is high, the positioning accuracy is high, the self-locking performance and the transmission stability are achieved, the lead screw transmission is not easily interfered by the outside, the sensor is mounted on the motor lead screw module, the position of a product is detected, movement in different directions is achieved, the movement coordination is increased, the detection efficiency is higher, the working efficiency is improved, and the motor lead screw module has the advantages of being good in stability, high in positioning accuracy and small in error.

In this embodiment, the knocking mechanism 9 includes a third motor screw module 10 and a third linear slide rail 11, the third linear slide rail 11 is disposed in a Z direction, and the third motor screw module 10 drives the knocking rod to slide on the third linear slide rail 11.
