Mainboard positioning and clamping device and mainboard detection equipment

Abstract

The invention provides a mainboard positioning and clamping device and mainboard detection equipment, belongs to the technical field of mainboard detection related test equipment, and solves problems that no positioning and clamping exist after a mainboard is placed, and the mainboard is inclined in place due to unstable movement process and movement inertia. The device comprises a base, a first connecting rod, a guide column, a clamping flange and a liftable mainboard carrier plate, a first support and a linear bearing seat are fixedly arranged on the base, a second support is fixedly arranged on the lower surface of the mainboard carrier plate, the first end of the first connecting rod is connected with the first support through a rotating shaft; the second end of the first connecting rod is connected with the second support through a rotating shaft, and the first end of the guide column is movably connected with the linear bearing seat. The mainboard placement process is optimized, the situation that the detection result is inaccurate due to the fact that the position of the mainboard is incorrect is avoided, a pure mechanical structure is adopted, and maintenance-free, long-service-life and reliable-performance effects can be basically achieved.

Problems solved by technology

[0002] At present, the incoming inspection of main boards is performed manually by personnel. First, there are problems such as long inspection time, slow movement, and low efficiency. Second, errors and omissions have occurred in manual inspection with naked eyes.

However, the introduction of existing automated testing equipment does not have an effective positioning method for the step of placing the main board. They are all manually carried and placed on the carrier board. The carrier board is driven by a motor or cylinder to the designated position, and the camera takes pictures. Analyze and test the process, and launch after the test is completed

However, in actual production, after the main board is placed manually, if no clamping mechanism is added, the main board will be slightly or heavily shifted during the movement with the carrier board. The principle of main board detection is that the camera captures the reflection of the needle. If there is any abnormality, the reflection of the pin will be inconsistent with others. If the position is shifted and skewed, after the light source is illuminated, the reflection of the pin will be inconsistent, which will affect the accuracy of the camera's visual judgment of the detection result, thereby affecting the accuracy of the final result.
