Jig cover plate disassembling and assembling mechanism of automatic chip discharging equipment

Abstract

The invention discloses a jig cover plate disassembling and assembling mechanism of automatic chip discharging equipment. The jig cover plate disassembling and assembling mechanism comprises an ejector pin mounting plate, wherein an ejector pin connecting plate is arranged above the ejector pin mounting plate through an ejector pin mounting plate connecting column, a mechanism mounting plate is arranged above the ejector pin connecting plate, an ejector pin air cylinder is arranged on the mechanism mounting plate through an ejector pin air cylinder mounting plate, and a push block of the ejector pin air cylinder is fixedly connected with the upper surface of the ejector pin connecting plate; a linear bearing mounting plate is arranged in the ejector pin mounting plate, a linear bearing isarranged on the edge of the linear bearing mounting plate, a cover plate attaching plate is arranged below the ejector pin mounting plate through a guide shaft arranged in the linear bearing, and theguide shaft is sleeved with a spring; and an ejector pin is arranged on the edge of the lower surface of the mechanism mounting plate, an ejector pin via hole and a magnet mounting groove are formed in the edge of the cover plate attaching plate, and a magnet or a vacant part is arranged in the magnet mounting groove. By means of the jig cover plate disassembling and assembling mechanism, a coverplate can be successfully sucked every time, the ejector pin cannot be clamped up and down, impact force on products is reduced, the production efficiency is high, stability is good, and practicability is high.

Description

technical field [0001] The invention belongs to the field of automatic chip unloading equipment, and in particular relates to a jig cover disassembly mechanism of the automatic chip unloading equipment, which is used for Lead Fream and chip handling. Background technique [0002] In the semiconductor industry, in order to speed up production, automatic chip unloading equipment equipped with a jig cover disassembly mechanism is usually used to transfer Lead Fream (lead frame) or chips quickly and orderly. The jig cover The board disassembly mechanism is used to open the jig cover plate with Lead Fream (lead frame) or chip, and continue to put the cover plate back on the jig bottom plate after the Lead Fream or chip is removed from the jig. [0003] Most of the existing Lead Fream jig cover plate disassembly mechanisms require manual disassembly and assembly of the cover plate. Although there are a few mechanisms that automatically disassemble the cover plate on the market, mo...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing Lead Fream jig cover plate disassembly mechanisms require manual disassembly and assembly of the cover plate. Although there are a few mechanisms that automatically disassemble the cover plate on the market, most of these mechanisms are not perfect in design. There will be situations where the jig cover cannot be removed, and the use effect is not ideal, which greatly reduces the production efficiency of the chip automatic cutting equipment

[0004] At the same time, the existing Lead Fream jig cover disassembly mechanism, due to the multiple magnets inlaid on the bottom of the jig, the cover will be tilted when taking the cover, which will cause the cover to be broken when closing the cover. The positioning pins on the bottom plate of the jig cannot be accurately placed, and the stability is low, which is also one of the problems that reduce the overall efficiency of the chip automatic unloading equipment
