Reference picture 7, Fig. 8, Figure 11, Figure 12 are described in detail, and detent mechanism 108 is generally constructed to comprising relative to each other Two parts of action are the conduct main composition key element of fixture 110 that action is opened and closed with second component for first component.Specifically For, fixed block 112 that fixture 110 is configured to include being fixed on loader main body, feed is held in a manner of it can swing The bar 114 of device main body.Incidentally, bar 114 plays function as a side of first component and second component, fixed block 112 Function is played as the opposing party of first component and second component.

Bar 114 is branched off into two-part mobile jib 116 by upper end and intersected using the part of the branch with the mobile jib 116 Secondary bar 118 is formed, and they can swing around general axle 120.The upper end of mobile jib 116 passes through work it can be seen from Figure 12 (a) Active force for the spring 122 of compression helical spring is exerted a force towards right, and the bottom of secondary bar 118 is by being used as compression spiral bullet The active force of the spring 124 of spring is exerted a force towards right.

Blade 126 is installed in the upper end of mobile jib 116, grip block 128 is installed in the upper end of secondary bar 118.In mobile jib 116 Bottom roller 130 is installed, as shown in figure 8, the roller 130 plays function as cam follower, in the first sliding part 72 In the case of advance, engage with the cam surface 132 located at the leading section of first sliding part 72.

Active force based on spring 122 is more than the active force based on spring 124, in the state of shown in Figure 12 (a), turns into Secondary bar 118 abuts with the back side of blade 126 and mobile jib 116,118 respective upper end of secondary bar are located at state, the i.e. fixture 110 of right The state of opening.In this condition, blade 126, grip block 128 separate with fixed block 112.

When the first sliding part 72 advances, the upper end edge of mobile jib 116 is swung towards the direction of left, therewith together, secondary bar 118 also swing in same direction.When above-mentioned mobile jib 116, secondary bar 118 are swung to a certain extent, as shown in Figure 12 (b), Element P lead Le shape is clamped between clamping face 134 located at fixed block 112 and the clamping face 136 located at grip block 128 Under state, stop the swing of secondary bar 118.The part provided with clamping face 134 of fixed block 112, grip block 128 are provided with clamping face 136 part plays function respectively as clamping part, using above-mentioned clamping part come clamping element P lead Le.In the state Under, lead Le is clamped by the power caused by the active force of spring 124.

In addition, when mobile jib 116 is swung, as shown in Figure 12 (c), top and the clamping of fixed block 112 using blade 126 The lower end cut-out lead Le in face 134.The top of blade 126, the lower end of the clamping face 134 of fixed block 112 are used as and are respectively arranged on The first component and a pair of blades of second component stated and play function, using a pair of blades, lead Le is by above-mentioned folder Cut the front (lower end side) for holding the part of portion's clamping.That is, element feeder 26 possesses in component feeding portion SS and is configured to Lead Le lead shut-off mechanism 138 is cut off by the on-off action of fixture comprising above-mentioned a pair of blades.

In component feeding portion, the cut-off lead Le of SS element by fixture 110 in the state of leaded Le is kept, by it The chuck assembly 36 of the mounting head 20 of preceding explanation is kept, and after fixture 110 is opened, moves the element by the mounting head 20 And it is used to install to substrate S.The opening action of fixture 110 is by making the first sliding part 72 retreat to utilize spring 122, spring 124 active force is carried out.The action between the closed position shown in open position and Figure 12 (b) shown in Figure 12 (a), i.e. The on-off action of fixture 110 is carried out along with the moving back and forth of the first sliding part 72, therefore the conveying mechanism with illustrating before 70 action linkage.

In addition, as shown in figure 11, set respectively in the end face of the end face of the front side of fixed block 112, the front side of mobile jib 116 Have blade 140, the blade 142 for cutting off carrier band CT, using the on-off action of fixture 110, cut-out feed element P and it is residual The carrier band CT stayed a part.That is, this element feeder 26 possesses band shut-off mechanism 143, and the band shut-off mechanism 143 utilizes blade 140th, the 142 cut-out carrier band CT in units of the pitch of holes p2 part for being removed element P.A cut-off carrier band CT part Scratch tape collection box 56 (reference picture 6) is recovered in by chute 144.

In this detent mechanism 108, two lead Le that element P has are respectively positioned in the conveying direction for changing element TP On appropriate location it is more important.Therefore, the side in first component and second component is the upper end of bar 114, specifically existed The grip block 128 for being installed on the upper end of secondary bar 118 is provided with guide portion 150.

Grip block 128 has the laminar projection piece 152 protruded from clamping face 136.The projection piece 152 formed with Two lead Le it is corresponding and in the case that fixture 110 is in the closed position towards the opposing party in first component and second component Two V-groove mouths 154,154 that i.e. fixed block 112 is open respectively.When fixture 110 is closed, projection piece 152 is to cover fixed block 112 mode moves, and using above-mentioned V-groove mouth 154,154, two lead Le is guided to assigned position, become V-groove mouth 154th, the position of 154 the lowest point.So, guide portion 150 is configured to include multiple Vs corresponding with element P lead Le quantity Type groove mouth 154.

According to element P species, lead Le quantity, diameter, lead Le position, the mutual intervals of lead Le etc. are each not It is identical, it is necessary to change quantity, shape, interval of V-groove mouth 154 etc. according to the element P being supplied to.For example, it is contemplated that Following detent mechanism：It is configured to, makes such detent mechanism 156 shown in Figure 13 (a), the main body of i.e. described grip block 128 Portion's (clamping part) is integrated with secondary bar 118, only makes the relatively thin directing plate 158 (guide portion) and member of the above-mentioned projection piece 152 of composition Part P is correspondingly changed.Figure 13 (a) shows normally to be clamped with element P lead Le state, still, in situation about so forming Under, it is possible to produce Figure 13 (b) and with the schematically unfavorable condition as shown in Figure 13 (c) of the viewpoint from side.Tool Body illustrates, for the conveying capacity of the band element TP caused by conveying mechanism 70 is incorrect or the original of any lead Le bending Cause, it is contemplated that any lead Le is not located at appropriate position, i.e., any lead Le is not accommodated in opening for corresponding V-groove mouth 154 It is intraoral.In this case, lead Le supports when closing fixture 110 with the part for not forming V-groove mouth 154 of directing plate 158 Connect, directing plate 158 is deformed into bending lead Le and the top ends of itself are lifted, and fixture 110 is likely to reach to appropriate Closed position.Incidentally, in the case where lead Le diameter is relatively thin, possibility especially increases.

In order to avoid situation as described above, in this element feeder 26, make the main part of grip block 128 with it is above-mentioned Grip block 128 is made in the state of the integration of projection piece 152, specifically, main part and projection piece are formed by a part 152, in units of grip block 128, changed according to element P.Due to structure as use, i.e. due to using projection piece The 152 higher structure of rigidity, in this element feeder 26, generating lead Le and be not located at the situation of appropriate location In the case of, can not close fixture 110 turns into the degree of appropriate location to the closed position of fixture 110.Thus, by confirming fixture Whether 110 closed position is in appropriate location, can easily verify that whether lead Le position is in appropriate location.

Iv) fixture closed position confirming mechanism

From the viewpoint of above-mentioned, in this element feeder 26, possess and clamped at component feeding portion SS by fixture 110 During element P lead Le for confirm the fixture 110 closed position, i.e. the fixture 110 close in the state of operating position Whether the fixture closed position confirming mechanism 160 of appropriate location is in.

Specifically, as shown in figure 11, in grip block 128, it is provided with the extension 162 that front is stretched out from secondary bar 118 And tested gaging hole 164 is formed there through in the extension 162, the light reflection-type arranged using the lower section that gaging hole 164 is detected at this Sensor 166 detect the tested gaging hole 164, whether detected by the sensor 166, be able to confirm that according to tested gaging hole 164 Whether the closed position of fixture 110 is in appropriate location.That is, this element feeder 26 is included as located at the one of grip block 128 Part is the tested gaging hole 164 of the detected portion of guide portion and is set to the sensor 166 of the object of detection, and composition has fixture Closed position confirming mechanism 160.

It is further described, sensor 166 is configured to, from upper surface irradiation light, and in its upper surface upward Receive the light of reflection.Also, the fully closed state of fixture 110 is that the closed position of fixture 110 is in the state of appropriate location, In this condition, the light from sensor 166 is reflected by the part of no detection hole 164, and the light is detected by sensor 166. Do not detect tested gaging hole 164 now, be determined as that the closed position of fixture 110 is in appropriate location.On the other hand, in fixture In the case that 110 closed position is not in the state of appropriate location, i.e. fixture 110 is not completely turned off, from sensor 166 Light do not detected through tested gaging hole 164, the light by sensor 166.Tested gaging hole 164 is detected at this moment, is determined as The closed position of fixture 110 is not in appropriate location.In addition, it is not in appropriate location in the closed position for being determined as fixture 110 In the case of, stop the action of the element feeder 26 and the action of component mounter 10.

Here, as a special situation, such as consider that lead Le is bent and the inclined situations of element P.In the situation Under, as shown in Figure 14 (a), it is contemplated that two lead Le are directed towards a V-groove mouth 154.In this case, as abnormal folder Tool, as shown in Figure 14 (c), in the case where fixture 110 is closed, the closed position of the fixture 110 is not in appropriate location.Figure 14 (b) state normally clamped is represented, and is relatively understood therewith, in the state of shown in Figure 14 (c), two lead Le are overlapping, because This fixture 110 can not completely close.This element feeder 26 located at the tested gaging hole 164 of grip block 128 by will be used as detection Object, also it is capable of detecting when that the state that a plurality of leads Le is directed towards a V-groove mouth 154 (below, is sometimes referred to as " lead weight Multiple state ").

However, made the appropriate closed position of fixture 110 different according to lead Le diameter, in order to confirm fixture 110 Closed position whether be appropriate location, it is necessary to account for.Specifically, in the diameter ratio shown in Figure 14 (b), Figure 14 (c) In the case of lead Le thin lead Le, turn into Figure 14 (d), Figure 14 (e) like that, the appropriate closed position of fixture 110 is different. In extreme situations, Figure 14 (b), Figure 14 (c) are used in the element P for the lead Le shown in Figure 14 (d), Figure 14 (e) In the case of shown grip block 128, even if in the state of clamping extremely, it is also possible to be determined as in the shape normally clamped State.

As previously described like that, in this element feeder 26, according to the element P of processing, replacing is provided with guide portion 150 Grip block 128.Moreover, the tested gaging hole 164 of detected portion is provided as in the grip block 128, i.e. its guide portion 150, In arbitrary grip block 128, i.e. in arbitrary guide portion 150, tested gaging hole 164 is arranged at being detected gaging hole 164 with this The lead Le of the corresponding element corresponding position of diameter.By grip block 128 as replacing, can save according to element P Enter trouble as the adjustment of the position of line sensor 166.

In addition, in view of the function of fixture closed position described above confirming mechanism 160, the fixture closed position confirm machine It is that (in the following description, sometimes referred to as " fixture confirms sensor to sensor 166 that structure 160, which is used as using optical sensor, 166 ") confirm element P whether so that appropriate state is delivered to component feeding portion SS confirming mechanism and plays function.

V) confirming mechanism is conveyed

In component feeding portion SS, in order to using above-mentioned detent mechanism 108 make element P, specifically be element P lead Le is located at assigned position, appropriately, is i.e. conveyed exactly with the conveying capacity of the band element TP caused by above-mentioned conveying mechanism 70 defeated Premised on sending spacing p3.In view of the situation, this element feeder 26 possesses for be confirmed whether will be with change using conveying mechanism 70 Element TP delivered conveying spacing p3 conveying confirming mechanism.

As shown in figure 8, between conveying mechanism 70 and detent mechanism 108 of the conveying confirming mechanism 170 on conveying direction. That is, located at the downstream of conveying mechanism 70 and it is the upstream side of detent mechanism 108.It is described in detail also referring to Fig. 9, Figure 10, Conveying confirming mechanism 170 be configured to include pin 172 from the sprocket hole FH insertions to the carrier band CT for being disposed through band change element TP, The pin 172 is set to be inserted into sprocket hole FH pin interposer 174 and for detecting whether by the pin interposer 174 by pin 172 are inserted into sprocket hole FH sensor 176.

If illustrating, pin 172 is kept by the oscillating rod 178 as movable body.By with the oscillating rod 178 and pin 172 Centered on Fig. 9 (c), Figure 10 (c) for illustrating as can be seen that by (omitting and illustrating) to the insertion axle of axis hole 180, with can be around the axle The mode that the central axis in hole 180 is swung is held in loader main body.Oscillating rod 178 is by the bullet as compression helical spring Spring 182 exerts a force towards left.On the other hand, roller 184 is arranged in the support bar 78 illustrated before, in the state that support bar 78 retreats Under, as shown in figure 9, the roller 184 abuts from left with the longitudinal wall part 186 of oscillating rod 178.Therefore, pin 172 is in direction guiding rail 62 The state of right displacement, i.e. the position with the conveying for changing element TP will not extremely be hindered by retreating.

When making support bar 78 advance, i.e. during using 70 conveyer belt element TP of conveying mechanism, as shown in Figure 10, roller 184 The position not engaged with longitudinal wall part 186 is advanced to, passes through the active force of spring 182, the displacement to the left of oscillating rod 178.Pin 172 The position of spacing p3 amounts (equal with sprocket hole FH pitch of holes p2) is conveyed on the front in the position than detent 96, therefore in profit In the case of correctly transporting conveying spacing p3 with element TP is changed with conveying mechanism 70, pin 172 to the left displacement and be inserted into Sprocket hole FH.That is, pin interposer 174 is formed comprising above-mentioned roller 184, oscillating rod 178 etc..Incidentally, by making support Bar 78 retreats, and roller 184 engages with longitudinal wall part 186, returns to the state shown in Fig. 9.
