Abstract

With the suction port (12a) of a suction unit (12) positioned in opposed relation to the air blow-off port (11a) of a blower (11), a work piece to be cut is positioned between the air blow-off port and the suction port and is cut by a cutting unit (16). The chips resulting from cutting are blown to gather at the suction port side by the air blown off from the air blow-off port and sucked by the suction unit. As a result, it is possible to ensure reliable prevention of the cut chips from scattering around.

Description

Shearing device

Technical field

The present invention relates to a kind ofly be cut off the shearing device of body, relate in particular to and to prevent and to be cut off the shearing device that the cut-out bits that produce when body cuts off disperse in order to cut off lead etc.

Background technology

General in the manufacturing process of electronics, electrical equipment etc., cut off bits cutting off can produce inevitably when lead terminal not etc. is cut off body.And when the lead terminal of not wanting being cut off or the vinyl shell of lead excised etc., cutting off bits disperses sometimes, cuts off dispersing of bits and can cause harmful effect to electronics, electric equipment.Therefore, in the manufacturing process of electronics, electrical equipment, when being cut off, lead terminal etc. must prevent to cut off dispersing of bits.

In the past, a kind of shearing device is arranged, for preventing to cut off dispersing of bits, for example as being cut off on the cutting nippers of workpiece of body cover is installed in order to cut off lead terminal etc., the attraction mouth of this cover is connected with suction device by attracting flexible pipe, and make switch close on the clamping plate base end part of cutting nippers, after moving, the cut-out that utilizes switch to detect lead terminal makes the suction device action, utilize cover to catch and cut off bits, and utilize suction device will cut off bits attraction, capture, thereby prevent to cut off disperse (for example with reference to the patent documentation 1) of bits.

In addition, also has a kind of shearing device, as comprising: will be cut off the clamp head part that body cuts off in order to cut off the cutting nippers that lead etc. is cut off the workpiece of body; Be installed on clamp head part, catch the cover of the smear metal that is cut off body that the blade utilize clamp head part cuts off; And the suction device that the smear metal that is cut off body that captures in the cover is attracted, import in the cover for being cut off body, be provided with peristome (for example with reference to patent documentation 2) at the leading section of cover.

Patent documentation 1: Japanese patent laid-open 8-10460 communique (the 3rd page～the 5th page, the 1st figure～the 5th figure)

Patent documentation 2: the Japan Patent spy opens 2001-251077 communique (the 5th page～the 6th page, the 1st figure～the 4th figure)

Because in the past shearing device adopts said structure, thus cutting nippers maximize because of cover is installed, thereby the operation of cutting nippers is difficult to carry out in cutting off operation, the utmost point that will become bothers if cut-off part fritters the operation of breaking very much.

In addition, in shearing device in the past, though in case capture to cut off with cover and just use suction device behind the bits and attract, capture, yet owing to the relation that is connected with suction device at the attraction mouth of cover, also make the operation of cutting nippers be difficult to carry out.

In addition, in shearing device in the past, only attract, capture cutting off bits by attraction, because the attraction power of suction device is limited, therefore when lead terminal etc. being cut off body cutting off, if it is at random at a distance to cut off bits, then can't utilize suction device to attract, capture to cutting off bits, therefore can cause to prevent to cut off dispersing of bits reliably.

For addressing the above problem, the object of the present invention is to provide a kind of when lead terminal etc. is cut off body and cuts off processing ease and can prevent to cut off the shearing device that bits disperse reliably.

Disclosure of the Invention

Shearing device of the present invention is characterised in that, comprising: the air-blast device with air blow-off outlet of blow out air; Have and be positioned at the locational suction device that attract mouth relative with the air blow-off outlet; And in order to cut off the cutter that is cut off body between air blow-off outlet and attraction mouth, air-blast device and suction device be separate configurations movably.

Adopt the present invention, owing to make and be cut off body and utilize cutter will be cut off the body cut-out between being positioned at the air blow-off outlet and attracting mouthful, blowed to the attraction oral-lateral so cut off the cut-out bits that produce when being cut off body by the air that blows out from the air blow-off outlet, therefore can attract, capture cutting off bits reliably.

The specific embodiment

Below, for illustrating in greater detail the present invention, with reference to the accompanying drawings most preferred embodiment is described.

Embodiment 1

Fig. 1 is the figure of the shearing device of the expression embodiment of the invention 1, at this, the example that the ends (following the end is called lead wire (Japanese: リ one De sheet)) that utilize 10 pairs of shearing devices to constitute the stator winding of part as motor is cut off processing describes.At Fig. 1 (a) and (b), illustrated shearing device 10 comprise air blast (air blows out device: air-blast device) 11 and attractor (suction device) 12, the attraction mouth 12a of the air blow-off outlet 11a of air blast 11 and attractor 12 relatively disposes.In illustrated embodiment, dispose between air blast 11 and the attractor 12 and receive board (cutting off the bits acceptance division) 13, this reception board 13 forms circular-arc.As indicated above, owing to cut off the relation of processing in this end, shown in Fig. 1 (a), make the outer peripheral face of stator core 14 will receive board 13 accordingly and form circular-arc with the inner peripheral surface that receives board 13 to stator winding.

Attractor 12 is connected with catch 15 by trap tube 12b, as mentioned below, from air blast 11 blow out air, move to (blowing to) attractor 12 sides with falling the cut-out bits that receive on the board 13, utilize attractor 12 to attract to cut off and consider to be worth doing and trap in the catch 15 by trap tube 12b.

Fig. 2 (a) reaches the figure of an example of the cutters such as cutting nippers 16 that adopt when (b) being expression cut-out lead wire, cutter 16 has clamp head part 16a, this clamp head part 16a is formed with a pair of blade 16b, if operating portion 16d is operated, then a pair of blade 16b closes along direction shown in the solid arrow among Fig. 2 (a), if then a pair of blade 16b will open with operating portion 16d separately.And, operating portion 16d is operated back blade 16b cuts off lead wire.On the other hand, being equipped with what have specific thickness along blade 16b is the maintaining part 16c of ester mouldings such as resin by silicon, and this maintaining part 16c has elasticity.

Next action is described.

With reference to Fig. 1, at first, after air blast 11 and attractor 12 driven, make the outer peripheral face of stator core 14 corresponding with the inner peripheral surface that receives board 13, lead wire (becoming the part of the cutting off bits) 14b that derives from lead terminal (being cut off body) 14a is positioned on the reception board 13, and makes lead wire 14b (being off-position) between air blow-off outlet 11a and attraction mouthful 12a.Utilize cutters 16 such as cutting nippers that lead wire 14b is cut off then.

As indicated above, because the blade 16b along cutter 16 is formed with rubber-like maintaining part 16c, therefore in that when lead wire 14b was cut off, maintaining part 16c was in the state of mutual butt with cutter 16 (being blade 16b), lead wire 14b maintained portion 16c clamps.Therefore, even lead wire 14b is cut off, lead wire 14b promptly cuts off bits and also can not disperse to not specific direction, and as if the 16b of portion that puts the first edge on a knife or a pair of scissors in the cut-out posttension, then the cut-out bits that kept by maintaining part 16c can be fallen and receive on the board 13.

Like this, because air blast 11 and attractor 12 are driven, so shown in the dotted arrow of Fig. 1 (a), falling air that the cut-out bits (lead wire 14b) that receive on the board 13 are blown out by the air blow-off outlet 11a from air blast 11 because of the cut-out of lead terminal 14a blows to (moving to) and attracts a mouthful 12a side, and be attracted device 12, thereby trap in the catch 15 by trap tube 12b from attraction mouthful 12a suction.

That is to say, as shown in Figure 3, cut off bits 21 and blowed to the direction that attracts mouthful 12a along solid arrow by the air that blows out from air blast 11.Then, because the attraction of attractor 12, arrival attracts near the cut-out bits 21 mouthful 12a to be attracted device 12 attractions reliably.Then, Yi Bian the outer peripheral face of stator core 14 is moved along the inner peripheral surface that receives board 13, Yi Bian whole lead wire 14b is cut off.When the cut-out of lead wire 14b is all finished, receive not exist on the board 13 and cut off bits, trap in the catch 15 and be attracted.

In addition, even when using common cutters such as cutting nippers (cutter that does not have maintaining part 16c), because air is blowed to the direction that attracts mouthful 12a by air blast 11, therefore cutting off bits can disperse to not specific direction hardly, attract a mouthful 12a side but be blown to, and be attracted device 12 attractions, become trapped in fully in the catch 15 thereby cut off bits.

Like this, cutter 16, air blast 11 and attractor 12 are constituted independently, thereby make that the operation of cutter 16 is extremely easy, and, blowed to an attraction mouthful 12a side owing to fall the cut-out bits that receive on the board 13 by air blast 11, therefore can easily utilize 12 pairs of attractors to cut off bits and attract, capture.And, blow to attractor 12 sides owing to utilize air blast 11 will cut off bits, so the attraction power of attractor 12 does not need very big (attraction power that is to say attractor 12 can be less).

Has the board 13 of reception in the example shown in Figure 1, yet receive board 13 and unnecessities, for example when on wiring substrate, lead wire being cut off when handling, substrate self can be used as and receives board 13 performance functions, therefore can make to cut off to consider to be worth doing and fall on the substrate, utilize air blast 11 that the bits of the cut-out on the substrate are blowed to and attract a mouthful 12a side, utilize 12 pairs of attractors to cut off bits and attract, capture.In addition, the shape of reception board 13 can corresponding have the electronics that is cut off body, the shape of electrical equipment is carried out suitable variation.

In addition, as indicated above, air blast 11 and attractor 12 dispose independently of each other, for example can utilize actuator etc. that the position of air blast 11 and/or attractor 12 is moved, thereby can corresponding electronics, the shape of the electrical equipment position of changing air blast 11 and/or attractor 12, therefore can avoid electronics, electrical equipment caused intrusively lead terminal etc. is cut off that body cuts off and attracts, capturing to cutting off bits.

Fig. 4 (a) and to be expression (b) cut off the figure of the example when handling to the unwanted lead wire of the lead terminal on the wiring substrate 22 at this, receives board 13 performance functions because substrate self can be used as, and therefore need not to set reception board 13.In addition, in Fig. 4, to the inscape mark identical reference marks identical with inscape shown in Figure 1.

In the illustrated embodiment, dispose a pair of guide way (air flue guide way) 23 of the path of the air that blows out from air blast 11 in order to regulation, this guide way 23 for example is tabular wall body, perpendicular to the surface configuration of wiring substrate 22, and from the direction extension of air blow-off outlet 11a to attraction mouthful 12a.And air flue is defined in 23 of a pair of guide waies.Shown in the dotted arrow of Fig. 4 (a), the air that blows out from air blow-off outlet 11a flows to an attraction mouthful 12a by air flue.At this moment, drop on cut-out bits 21 on the wiring substrate 22 and blowed to by the air that blows out from air blow-off outlet 11a and attract a mouthful 12a side, be attracted device 12 then and attract and trap in the catch 15.

Like this, the path of the air that will blow out from air blast 11 is defined on the substrate, therefore can the air that blow out is side directed to attraction mouthful 12a reliably, can not blow the place of flying to beyond attractor 12 sides from the air of air blast 11 stream, attract thereby can utilize 12 pairs of attractors to cut off bits 21 reliably with cutting off bits 21.

In addition, when cutting off processing, utilize driving guide waies 23 such as actuator, guide way 23 is dropped on the wiring substrate 22, form air flue at

air blast

11 and 12 of attractors thereby make cut-off part be positioned at air flue ground.

As indicated above, adopt the words of present embodiment 1, owing to lead wire is cut off lead wire between air blow-off outlet and attraction mouth, the cut-out that produces when cutting off lead wire is considered to be worth doing blowed to the attraction oral-lateral, and attract reliably, capture by the air that blows out from the air blow-off outlet.And because cutter 16, air blast 11 and attractor 12 all constitute independently, the processing ease when therefore cutting off lead wire carries out.

Adopt this embodiment 1 and since the air blow-off outlet with attract mouthful between dispose in order to receive the reception board 13 of the cut-out bits that produce when cutting off lead wire, therefore absorbing cutting off bits, when capturing, do not having cut-out and consider to be worth doing and fall.

Adopt this embodiment 1, utilize guide way 23 regulations to lead to the air flue that attracts mouth from the air blow-off outlet, and make the off-position that is cut off body be positioned at air flue, therefore can guarantee reliably that air stream flows to the attraction mouth from the air blow-off outlet, make and cut off bits, the leakage of cutting off bits is caught preventing reliably to attracting oral-lateral to move.

Adopt this embodiment 1, comprise rubber-like maintaining part 16c, becoming the part of cutting off bits when cutting off lead wire with a pair of blade 16b with cutter 16 clamps and keeps cutting off bits, therefore when cutting off lead wire, cut off bits and can not disperse, thereby can attract, capture cutting off bits reliably to not specific direction.
