Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of x-ray detection, and particularly relates to an x-ray full-automatic online detection machine for large and thin plates. BACKGROUND

[0002] In the x-ray detection and transfer feeding mechanism for large and thin PCBs or IC boards (500mm*600mm*0.15mm), the following problems exist:

[0003] 1) Most of the structures adopt clamping jaws or manual transfer feeding and discharging. The clamping jaw structure exerts clamping force on both sides of the thin plate, and the clamping force is large, which easily damages the material. Manual transfer feeding and discharging has low efficiency and high labor cost.

[0004] 2) When feeding, most of the existing detection machines use a material frame for storage. When the material frame is fed, the positions of the material frames are not accurate. If the material frame is placed obliquely, it will affect the subsequent clamping and positioning process (most of which adopt a clamping jaw structure), and thus affect the production process and reduce the work efficiency.

[0005] 3) The conveying and feeding are performed by a conveying belt, that is, two conveying mechanisms are arranged at intervals, and the two ends of the PCB are arranged on the conveying belt of the conveying mechanism. For large and thin PCBs or IC boards (500mm*600mm*0.15mm), this conveying and feeding method does not have a supporting point in the middle of the material, which affects the stability of the material support. In addition, the conveying method of the conveying belt is a contact type conveying, which has high wear of the conveying belt and easily generates dust, which affects the material detection.

[0006] 4) When the material is transferred and discharged, the position of the material needs to be adjusted to ensure that the material is accurately placed into the material frame. However, the existing transfer and discharge mechanism does not have a corresponding adjusting mechanism, and the transfer and discharge are not convenient. SUMMARY

The two vertical ends of the lifting bracket 123 are inserted between the two material frame supporting mechanisms 11. One limiting plug 124 is arranged on each side of the U-shaped horizontal end of the lifting bracket 123. The Z-axis lifting assembly 122 can adopt the transmission mode of a motor lead screw. When working, the motor can drive the material frame to rise (one end of the material frame is also provided with a limiting groove, and the limiting plug 124 is inserted into the limiting groove to ensure the stability of the material frame rising) to a predetermined position through the lifting bracket 123. After the material frame is clamped by the material frame clamping mechanism 14, the material frame lifting mechanism 12 can be lifted to a predetermined position (the feeding position) by the material frame lifting mechanism 12.

In addition, a pressure prevention mechanism 37 is arranged on one side of the lifting profile frame 353. When the suction nozzle lifting mechanism 352 drives the lifting profile frame 353 to press and suck the material, the sensing sheet on the top of the bumper can trigger the limit switch to prevent it from descending too much and damaging the material, thereby ensuring the safety of the material transfer. In addition, a position sensor 29 is arranged on the top of the lifting profile frame 353 to sense the position of the lifting profile frame 353, further improving the safety of the operation. At the same time, the spacing between the fixed suction nozzle mechanism 35 and the movable suction nozzle mechanism 36 can be adjusted by the spacing adjustment mechanism 34, which is suitable for the transfer of materials of different sizes and has strong versatility.
