Laminate drop prevention mechanism for PCB (Printed circuit board) laminate trolley

Abstract

The invention discloses a laminate drop prevention mechanism for a PCB (Printed circuit board) laminate trolley. Both left and right of the trolley are provided with side retaining plates higher than a trolley-top; both the front and rear ends of the trolley are provided with moving retaining plate mechanisms; the moving retaining plate mechanism comprise moving frames mounted at front and rear ends of the trolley, each moving frame is formed by connecting an upper cross beam and two vertical rods which are parallel, the lower ends of the vertical rods are all fixed on the trolley, the upper ends of the vertical rods are connected with the upper cross beams, and the upper beams and the vertical rods are connected through bolts and nuts. The upper cross beams and the vertical rods can be adjusted in a vertical state, the upper cross beams form retaining plates preventing laminate drop, dropping of laminates can be fully avoided, abandonment loss caused by laminate drop is fully avoided, and possible industrial accidents caused by laminate drop are fully avoided. When prevention is not required, the vertical rods and the upper cross beams can be adjusted in a non-vertical state, the upper cross beams are lower than the trolley-top.

Description

technical field [0001] The invention belongs to the field of equipment for manufacturing printed circuit boards, and in particular relates to a trolley structure for back and forth transporting PCB laminated boards. Background technique [0002] In the prior art, the PCB laminated board needs to be transported back and forth on the transfer trolley, and the trolley is transported back and forth along the track. Generally, in order to prevent the plywood from falling off the trolley, baffles are provided on the left and right sides of the trolley (that is, parallel to the track). Due to the existence of the above-mentioned baffles on the left and right sides, the trolley generally There will be no board drop. However, even if baffles are provided on the left and right sides of the trolley, when the manual operation is unskilled or improper, the pressure plate may still fall due to the instability of the trolley's running speed and inertial force. In order to completely elim...

AI Technical Summary

Problems solved by technology

However, even if baffles are installed on the left and right sides of the trolley, when the manual operation is unskilled or improper, the pressure plate may still fall due to the instability of the trolley's running speed and inertial force.

In order to completely eliminate the scrap loss caused by the falling of the pressed plywood and the work-related accidents that may be caused by the falling of the plywood, this technical defect that may affect the yield and the safety hazard that may cause employee injuries must be resolved.
