Abstract

The utility model discloses a pneumatic pin cutting machine, which comprises a movable cutter and a fixed cutter. The fixed cutter is installed on a fixed cutter seat of a base, the movable cutter is installed on a pneumatic lifting mechanism above the base, and the movable cutter and the fixed cutter are in cutting match with each other at a front-back position. The cutting edge of the fixed cutter is the intersecting line of the fixed cutter rear lateral face and the fixed cutter top face. The width of the fixed cutter top face is smaller than the length of a pin of a liquid crystal display. The height of the front lateral face of the fixed cutter is small than or equal to the distance between the pins on two sides of the liquid crystal display. The pneumatic pin cutting machine utilizes a pneumatic lifting mechanism as a lifting device and drives the movable cutter to move vertically, thereby finishing trimming to the pins of the liquid crystal display and greatly improving production efficiency. Only two operators can manufacture 35000pcs in one day. The trimming control precision can reach to -0.3mm to 0.3mm, and rejection rate is lowered.

The pneumatic PIN pin machine of cutting
Technical field
The utility model relates to the manufacturing field of LCD, is specifically related to a kind of pneumatic PIN of cutting pin machine that is used for cutting liquid crystal display PIN pin.
Background technology
In the existing cutting machine to LCD PIN pin; Be full manual operations mostly, it mainly comprises moving knife and the stationary knife that has operating grip, and moving knife and stationary knife are connected through the hinge; Moving knife can rotate up and down around hinge, and stationary knife is fixedly connected on the supporting seat of moving knife below.When LCD PIN pin was cut, handgrip of workman LCD PIN pin to be cut was placed on the stationary knife, and an other then hand rotates moving knife, accomplishes the cutting to LCD PIN pin.Such cutting machine needs total man worker to intervene, and service speed is slow, and production efficiency is low, and six people's production production capacities just can reach 30000pcs/ days; And but control accuracy is low, can only reach-0.8mm~0.8mm, and more the product of high-precision requirement then can't be produced; And strengthen workman's manipulation strength, make the workman very easily tired out, bring potential safety hazard.
The utility model content
The utility model technical problem to be solved provides and a kind ofly cuts high efficiency, the pneumatic PIN pin machine of cutting that control accuracy is high from automatically navigating to.
For addressing the above problem; The pneumatic PIN of the cutting pin machine that the utility model designed comprises moving knife and stationary knife, and said stationary knife is installed on the stationary knife seat of base; Said moving knife is installed on the air lifter of base top, and moving knife and stationary knife are done to shear in anteroposterior position and cooperated; The cutting edge of said stationary knife is the intersecting lens of stationary knife trailing flank and stationary knife end face, and stationary knife end face width is less than the PIN pin length of LCD, and stationary knife leading flank height is less than or equal to the distance between the PIN pin of LCD both sides.When LCD PIN pin is cut, start air lifter, be buckled in LCD side to be cut on the stationary knife, let the PIN hem facing be combined on the stationary knife end face, air lifter drives moving knife and moves up and down, and accomplishes cutting of PIN pin.
In order to regulate the length of PIN pin, said stationary knife leading flank is provided with the adjustment pad.
The said air lifter of such scheme comprises the cylinder that the moving knife guide plate that moves along the vertically-guided groove and moving knife guide plate upper fixed are installed; The downward cylinder rod of cylinder connects the moving knife guide plate; Moving knife is installed on the moving knife guide plate, and said gathering sill splits both sides and is slidingly matched with the two sides of moving knife guide plate respectively.
The said cylinder of such scheme is installed on through cylinder block on the backboard of stationary knife rear side, and backboard is installed on the base; Said gathering sill is opened on the side plate, and side plate is installed on the backboard.
For moving knife is adjusted, improve the quality that cuts, said moving knife is installed on the moving knife guide plate with adjustable way up and down.
The said stationary knife of such scheme is installed on the stationary knife seat with the front and back adjustable way.
Compared with prior art, the utlity model has following advantage:
1, adopt cylinder as drive unit, drive the moving knife knee-action, completion cuts LCD PIN pin, has improved production efficiency greatly, as long as 2 operating personnel's production capacities then can reach 35000pcs/ days;
2, the position of moving knife and stationary knife all is adjustable, can improve the control accuracy that cuts, and its control accuracy can reach-0.3mm~0.3mm, has reduced scrappage, has improved the utilization rate of product;
3, adopt cylinder as drive unit, reduced workman's working strength, reduced potential safety hazard.
Description of drawings
Fig. 1 is a kind of pneumatic structural representation of cutting PIN pin machine of the utility model;
Label is among the figure: 1, moving knife; 2, stationary knife; 3, base; 4, stationary knife seat; 5, moving knife guide plate; 6, cylinder; 7, cylinder block; 8, backboard; 9, side plate.
The specific embodiment
A kind of pneumatic structural representation of cutting PIN pin machine of the utility model is as shown in Figure 1; Comprise moving knife 1 and stationary knife 2; Said stationary knife 2 is installed on the stationary knife seat 4 of base 3, and said moving knife 1 is installed on the air lifter of base 3 tops, and moving knife 1 is done to shear in anteroposterior position with stationary knife 2 and cooperated; The cutting edge of said stationary knife 2 is the intersecting lens of stationary knife trailing flank and stationary knife end face.For the PIN pin is positioned on the cutting edge of stationary knife 2, completion cuts LCD PIN's, and stationary knife end face width is less than LCD PIN pin length; Because LCD all has the PIN pin in both sides up and down, is fastened on the stationary knife 2 in order to make its side direction, stationary knife leading flank height is less than or equal to the distance between the PIN pin of LCD both sides.When LCD PIN pin is cut; Start air lifter; Moving knife 1 is done shuttling movement up and down under the draw of air lifter, the staff is according to the motion frequency of moving knife 1; Be combined in LCD PIN climbers on the stationary knife end face, the frequency of air lifter can adjust according to staff's situation.
Said air lifter comprises that along vertically-guided groove moving knife guide plate 5 that moves and the cylinder 6 that is fixedly mounted on moving knife guide plate 5 tops cylinder 6 downward cylinder rods connect moving knife guide plate 5, and moving knife 1 is installed on the moving knife guide plate 5.Back side at base 3; One backboard 8 perpendicular to base 3 is installed, is respectively equipped with the side plate 9 that is installed on the backboard 8, on side plate 9, offer gathering sill in moving knife guide plate 5 both sides; Said gathering sill is slidingly matched with the two sides of moving knife guide plate 5 respectively; Moving knife guide plate 5 slides up and down along gathering sill under the draw of cylinder rod, and then drives the shuttling movement up and down of moving knife 1.
Said moving knife 1 is installed on the moving knife guide plate 5 with adjustable way up and down, and in this preferred embodiment, the adjusting mounting means that is adopted is: moving knife 1 is tightened against on the moving knife guide plate 5 through the slot on the moving knife 1 with bolt.
On the leading flank of stationary knife 2, be provided with through changing the thickness degree and regulate the adjustment pad of PIN pin cutoff length.In order to regulate the cutting gap of moving knife 1 and stationary knife 2, described stationary knife 2 is installed on the stationary knife seat 4 with the front and back adjustable way.
