Abstract

The utility model relates to a carrier of corner cutter for PC plate, which comprises a left guide rail, a right guide rail, chain wheels, a chain, a guide vane, and a plurality of carriers. The chain wheels used for driving the chain are respectively arranged on the front ends and the back ends of the left and the right guide rails, A plurality of carriers used for carrying a circuit board to carry out the cut of the pull corner are pivoted on the lower part of the junction of the chain. A guide groove is arranged on one side of a plurality of carriers. The guide vane which is arranged along the lower part of the chain can be embedded into the guide groove So a plurality of carriers can move along the guide vane when driven by the chain, and the stability is enhanced. The part used for carrying the circuit board and arranged on the lower part of the carriers is made into a square-shaped face to increase the area for carrying the circuit board, and the steadiness at pulling corner cutting by the circuit board can be enhanced.

Description

Carrier of angle cutter for PC plate

The utility model relevant a kind of " year seat of circuit board cutter ", mainly be by two left sides, right guide rail, the number sprocket wheel, two chains, bi-conductive plate and some years seats are formed, wherein two left and right rails before, rear side respectively is provided with a sprocket wheel, drive this chain movement by this sprocket wheel, some years seats in addition are pivoted in this chain junction, and establish a guide groove in the side of this some years seats, make and place the guide card of this chain below can embed in this guide groove, except that making a year seat when mobile, have the high stability, more but the circuit board of clamping different shape makes it be beneficial to the cut-out that circuit board is transported persons or goods by cart.

Press, electrical appliance and our life are closely bound up, inseparable, the general employed household electrical appliances of family (as TV, sound equipment, microwave oven etc.) all need circuit board as its assembly, and therefore, the demand of circuit board is quite big, so, how making the fabrication schedule of circuit board shorten, reduce cost, and improve its quality, is that people expect.Only, the bearing of the circuit board cutter of commonly using is circular up and down, if desire clamping area is less or outer rim is circular circuit board, make circuit board from the guide rail landing because of the design of bearing is bad easily, make the operator when operation, very perplex, circuit board is not of uniform size in addition, carry seat and directly be hubbed at below, chain junction,, then carry when a bearer circuit plate is advanced and to produce shaking phenomenon if do not give suitable clamping because of operator's carelessness, effect is unclear when making it cut off, and reduces product quality.

The purpose of this utility model is to provide a kind of seat that carries of circuit board cutter, and the phase makes when carrying seat clamping circuit board more smooth-going, and this in addition year seat has good clamping effect to the circuit board of Any shape, can improve the production quality.

The purpose of this utility model is achieved like this: a kind of year seat of circuit board cutter, and it is made up of two left and right guide rails, sprocket wheel, chain, guide card and some years seats, and wherein the front and back ends of two left and right guide rails is respectively established a sprocket wheel.Drive this chain by this sprocket wheel, some years seats in addition are pivoted in the below, junction of this chain, the cut-out of transporting persons or goods by cart in order to the clamping circuit board, one side of this some years seats is provided with a guide groove, and a guide card is established in the below of this chain along the line, the guide groove of this some years seat sides can be embedded this guide card, this some years seats can obtain advantages of higher stability because of moving along guide card, and the base system of this some years seat outside bearer circuit plates is square, this measure is the clamping circuit board smoothly, and is applicable to the circuit board of different shape.

Following conjunction with figs. and embodiment further specify the utility model

Brief description of drawingsfig:

Fig. 1 is a position view of the present utility model.

Fig. 2 is that the utility model is connected the enforcement illustration with chain

Fig. 3 is that section of the present utility model is implemented illustration

Fig. 4 commonly uses to carry seat clamping circuit board enforcement illustration

Fig. 5 commonly uses the position view that carries seat.

See also accompanying drawing, the utility model is respectively to establish a sprocket wheel 3 in the front and back end of left and right guide rail 1,2, drives a chain 31 by sprocket wheel 3, and the some years seats 4 that are pivoted in right side, chain 31 junction; When chain 31 when sprocket wheel 3 drives, also drive year seat 4 that is hubbed at chain 31 downsides simultaneously, a guide groove 41 is established in the side of carrying seat 4, the guide card 5 that is provided with along chain 31 belows is embedded in the guide groove 41 that carries seat 4 sides, seat is carried in order can obtain the higher travel path of stability when motion, and be made as plinth in the base of guide groove 41 another sides of carrying seat 4, can press from both sides the circuit board 6 of Any shape, when circuit board 6 is inserted left and right rail 1, after 2, move ahead via the clamping that carries seat 4, and cut off transporting persons or goods by cart of circuit boards 6 with cutoff tool 7, the deflection of its circuit board 6 is minimized.

Other sees also Fig. 4, commonly using a year seat 4 is directly to lock in admittedly under the chain 31, if the too small or rounded shape of outer rim of circuit board 6 areas, then circuit board very easily carries seat 4 places landing, and the seat of commonly using 4 that carries only is to be driven by the directly solid lock of chain 31, and when carrying seat 4 clamping circuit boards 6 and cut pin, there is no guide card can be for guiding, therefore stable not good enough during circuit board 6 is advanced, cutting effect is reduction relatively also.

In sum, the utility model provides a kind of travel path of high stability, make circuit board in advance or cutting-off process in, can not influence the effect of cut-out because of the vibrations of carrying seat, in addition can be for the circuit board of placing Any shape, be not subjected to the change of circuit board outer rim and influence its clamping effect.

Claims

1, a kind of year seat of circuit board cutter, it is characterized by: it is by two left sides, right guide rail, sprocket wheel, chain, some years seats of guide card are formed, two left sides wherein, before the right guide rail, a sprocket wheel is respectively established in the rear end, drive this chain by this sprocket wheel, some years seats in addition are pivoted in the below, junction of this chain, the cut-out of transporting persons or goods by cart in order to the clamping circuit board, one side of this some years seats is provided with a guide groove, and establish a guide card along the below of this chain, the guide groove of this some years seat sides can be embedded this guide card, this some years seats can obtain advantages of higher stability because of moving along guide card, and the base of this some years seat outside bearer circuit plates is to be square, this measure is the clamping circuit board smoothly, and is applicable to the circuit board of different shape.
