Machine for automatically cutting PIN feet

Abstract

The invention discloses a machine for automatically cutting PIN feet, comprising a movable cutter and a fixed cutter, wherein the fixed cutter is arranged on a bottom plate; the movable cutter is arranged on a pneumatic lifting mechanism; the movable cuter and the fixed cutter are matched with each other in a sheared way at the left position and the right position; the bottom plate at the left side or the right side of the fixed cutter is provided with a feeding slot that is connected with the fixed cutter; the bottom plate at the other side of the fixed cutter is provided with a positioning block; the pneumatic lifting mechanism comprises a gas cylinder fixed above the bottom plate; a gas cylinder rod of the gas cylinder extending downwards is connected with a movable cutter seat; the movable cutter is arranged on the movable cutter seat; the fixed cutter and the positioning block are used as conduction switches that are communicated with a gas cylinder control circuit and lead the gas cylinder rod to move from an initial position to a cutting position, and are also used as conduction switches that are communicated with a PIN foot counter circuit and lead the PIN foot counter circuit to count; and a travel switch or a proximity switch leading the gas cylinder to recover is arranged at the cutting position of the movable cutter. The machine for automatically cutting the PIN feet has the advantages of high production efficiency, high product utilization ratio and zero counting error.

Description

(1) Technical field: [0001] The invention and the field of manufacturing liquid crystal displays specifically relate to an automatic PIN cutting machine for cutting metal lead-out pins. (two) background technology: [0002] The industrialized production of liquid crystal displays requires a large number of single-piece metal lead-out pins, and the single-piece metal lead-out pins are cut from rolls of metal lead-out pins. The traditional cutting method is manual operation, that is, a manually operated rotary cutter, including a moving knife and a fixed knife with an operating handle, the moving knife and the fixed knife are connected by a hinge, the moving knife can rotate up and down around the hinge, and the fixed knife is fixedly connected On the supporting seat below it, the length positioning block is also arranged on the supporting seat next to the fixed knife. When cutting the metal pin, one hand pulls out the metal lead-out strap and places it on the fixed knife. Th...

Problems solved by technology

[0003] This kind of manual cutting machine needs manual intervention completely, the operation speed is slow, and the production efficiency is low. Four people can only cut 20,000pcs per day, the scrap rate is 2.3%, and the manual counting is not accurate. In addition, this manual cutting machine has a short service life and the tooling is monthly To invest tens of thousands of yuan, the production cost is high, the labor intensity of the workers is high, and there are potential safety hazards
