The specific embodiment
Following with reference to description of drawings the specific embodiment of the present invention, make the present invention clearer.
(first embodiment)
Fig. 3 (a) is the block diagram of the electronic component that is transmitted in first embodiment of the present invention.Electronic component 1 is a multi-layer ceramic capacitor, has rectangular shape.That is, electronic component 1 has rectangular-shaped ceramic sintered bodies 2.Shown in Fig. 3 (b), (c), in ceramic sintered bodies 2, overlapping a plurality of internal electrodes 3 through ceramic layer.In the present embodiment, internal electrode 3 has ferromagnetism based on nickel.As long as the internal electrode as the electronic component of object of the present invention has ferromagnetism, can make with suitable material.
Be formed with first, second outer electrode, it covers first, second end face 2a, the 2b that face mutually of ceramic sintered bodies 2.Is the direction of first end face that connects electronic component 1 and the second end face 2a, 2b that size on the electronic component length direction is made as L; Is a plurality of internal electrodes 3 that the size of short transverse is made as thickness T through the stacked direction of ceramic layer; The size of the direction that couples together between a pair of side is made as width W.Therefore, the face direction setting with a plurality of internal electrodes 3 is and the length L of above-mentioned electronic component 1 and the parallel direction of direction of width W that the direction of above-mentioned thickness T just becomes the direction with internal electrode 3 quadratures.
In electronic component 1, width W and thickness T are less than length L, and width W and thickness T are equal substantially.
In electronic component conveying equipment 11, must supply with a plurality of electronic component 1 marshallings, and make above-mentioned a plurality of internal electrode 3 towards unanimity.
Electronic component conveying equipment 11 shown in Figure 1 can and make transmitting of internal electrode 3 in following a plurality of electronic component 1 marshallings of the situation that transmits a plurality of electronic components 1 after unanimity.
Electronic component conveying equipment 11 has transfer path member 12.This transfer path member 12 begins to constitute first transfer path 13, rotation path 14 and second transfer path 15 from upstream side.
The first transmission table top 13a, second transmits table top 14a and the 3rd transmission table top 15a links up plane of formation.
Also can only on the first transmission table top 13a, inclination be set, its height is reduced towards rotation path 14 sides, also can only transmit on the table top 13a and the second transmission table top 14a inclination is set, make its side reduction highly towards downstream first.That is, also can transmit more upstream side place of table top 15a than the 3rd, only local above-mentioned inclination is being set.
As mentioned above, in first transfer path 13, rotation path 14 and second transfer path 15, owing to electronic component is moved, on first to the 3rd plane transmission table top 13a～15a under the face state of contact so electronic component 1 just is transmitted under stable status at it.
On the other hand, in electronic component 1, width W and thickness T are less than length L, and width W and thickness T are equal substantially.A plurality of electronic components 1 that consideration is made from the upstream side confession of first transfer path 13, in this case, as supplying the electronic component 1 of coming, the face direction of the internal electrode 3 of some electronic component 1 is towards horizontal direction, and the face direction of the internal electrode 3 of some is then towards vertical direction.In the present embodiment, in rotation path 14, make such electronic component 1 internal electrode 3 towards unanimity.
In first transfer path 13, in order to transmit above-mentioned electronic component 1 along its length reposefully, W1 just must be shorter than length L at interval.Otherwise, the linking a pair of first and transmit spigot surface 13b, 13c of electronic component 1 towards just becoming its length direction.
Equally, in second transfer path 15, W3 also must be shorter than length L at interval.
On the other hand, stand upside down in order to prevent electronic component 1, the height of first transfer path 13, rotation path 14 and second transfer path 15 is the length L that the height H among Fig. 1 (b) must be lower than electronic component 1.
Among Fig. 1,, and in fact be provided with top board 17 (with reference to Fig. 2), be used for the top opening portion of first transfer path 13, rotation path 14 and second transfer path 15 of coverage diagram 1 though omitted the diagram of top board.Top board 17 may not cover the whole top opening of transfer path.As long as can prevent the handstand of above-mentioned electronic component 1, only that top board is set is just passable in the part, also netted top board can be set.
Therefore because internal electrode 3 has ferromagnetism, so be transferred to electronic component 1 on the rotation path 14 just be changed towards, make the face direction of internal electrode 3 consistent with the bearing of trend of above-mentioned magnetic line of force Z.For example, under the situation that internal electrode 3 extends along the vertical direction, the direction that above-mentioned magnetic line of force Z extends and the bearing of trend basically identical of internal electrode 3, therefore, electronic component 1 just keeps should be towards passing through rotation path 14, and be sent to second transfer path 15.
On the other hand, under the situation of horizontal direction, the effect of above-mentioned magnetic line of force Z makes electronic component 1 rotate around length direction at the internal electrode 3 of electronic component 1, make internal electrode 3 become shown in Fig. 1 (c) towards.That is, electronic component 1 rotates 90 ° around the center shaft that extends along its length, make internal electrode 3 towards becoming the direction shown in Fig. 1 (c).
Therefore, in rotation path 14, make electronic component 1 towards unanimity, by the internal electrode 3 of the electronic component 1 sent here all towards above-below direction.
Because W2 is shorter than L at interval, so it is consistent with the direction that links guide wall 14b, 14c that the length direction of electronic component 1 is gone to mistakenly.
On the other hand, in rotation path 14 since at interval W2 than W1 at interval or W3 is wide at interval, so though the internal electrode 3 of electronic component 1 through adjusting towards correctly, its length direction might intersect with direction of transfer.
For this, in the present embodiment, owing to be provided with second magnet 22 in the downstream of first magnet 21, so can positively keep internal electrode 3 correct direction to supply to second transfer path 15 unchangeably towards correct electronic component 1.In the present embodiment, the part that the ratio in rotation path 14 is provided with first magnet 21 is the downstream more, and is guide wall 14c one side with a relative side of a side that is provided with first magnet 21, second magnet 22 is arranged on the outside of guide wall 14c.As shown in Figure 4, the magnetic force of this second magnet 22 makes towards correct electronic component 1 and leans against guide wall 14c side, and is attracted on the inside face of the second guide wall 14c.Therefore, be attracted to towards correct electronic component 1 on the inside face of the second guide wall 14c, it is towards keeping stably being moved to the downstream.
In this case, if the magnetic force of second magnet 22 is strong excessively, electronic component 1 is moved as the soruce of vibration 16 of forwarder.Therefore, the magnetic force of second magnet 22 must be made and not hinder forwarder to make electronic component 1 size of side shifting downstream.
The length dimension along direction of transfer of above-mentioned rotation path 14 is preferably made 2.0 times of the length L that is equal to or greater than above-mentioned electronic component 1.In rotation path 14, adjust electronic component 1 towards during, also make electronic component side shifting towards downstream constantly.Though therefore the lengthwise dimension along direction of transfer in rotation path 14 must reach to a certain degree, but to keep the degree of posture of above-mentioned electronic component just passable as long as its length is the magnetic force of first magnet, under the situation longer, keep posture with second magnet than it.
If the length dimension along direction of transfer of rotation path 14 equals 2.0 times greater than L, in rotation path 14, electronic component 1 is easily rotated around the center shaft along its length direction, can be correctly towards.The length dimension along direction of transfer at rotation path 14 is shorter than under the situation of 2.0 times of L, though also the magnetic force that produces because of the transfer rate of electronic component 1 and first magnet 21 is different, may be difficult to make reliably electronic component 1 all to adjust on the correct direction.
With respect to the width W of electronic component 1, preferably interval W2 is set in 1.03 * (W
2+ T
2)
1/2～1.06 * (W
2+ T
2)
1/2Scope in.If in this scope, move by vibration with regard to not harming electronic component 1, can make electronic component 1 serves as that axle rotates naturally with its length direction, thereby points toward the same.Under the situation of interval W2 less than above-mentioned scope because the Width size in the rotation path 14 is big inadequately, so be difficult to positively to make electronic component 1 towards unanimity.Under the situation of interval W2 greater than above-mentioned scope, though making electronic component 1 easily serves as that axle rotates with its length direction, even but made towards unanimity, the action of electronic component 1 is also unstable, the mobile gesture unrest of can bursting, might in rotation path 14, assemble a plurality of electronic components, and rotation path is stopped up.
In rotation path 14, though guide wall 14b and guide wall 14c are spaced from each other interval W2 and face mutually, guide wall 14b, 14c have mobile guide face 14b1,14c1 at upstream side.In mobile guide face 14b1,14c1, narrow down gradually towards the upstream from interval W2 at interval, up to becoming W1 at interval.Therefore, electronic component 1 nature of supplying with to rotation path 14 from first transfer path 13 can be directed to the rotation path 14.
Certainly, as mentioned above, above-mentioned mobile guide face 14b1,14c1 also can not be at interval gradual changes, but extend along the direction perpendicular to transfer path.In this case, just become the mobile guide wall that the broad ways extension is set in first transfer path 13 and the connecting portion office of rotation path 14.
In the downstream of rotation path 14 part, above-mentioned first, second guide wall 14b, 14c also have mobile guide face 14b2,14c2.Interval between mobile guide face 14b2, the 14c2 is W2 at upstream extremity, holds constriction gradually towards downstream from W2, and constriction is to interval W3 always.Mobile guide face 14b2,14c2 make the interval between a pair of guide wall hold constriction gradually towards downstream.This mobile guide wall naturally just electronic component 1 with correctly in second transfer path 15 that imports the interval W3 narrower than interval W2 with remaining unchanged.
Correctly be not that axle rotates in towards second transfer path 15 of electronic component 1 with the length direction at interval W3.Therefore, correctly towards electronic component 1 be imported into the downstream of second transfer path 15.
Like this, according to present embodiment, a plurality of electronic components 1 when its length direction transmits, just can positively make electronic component towards unanimity, so that the thickness direction of internal electrode is the direction of regulation.
And can stably supply with a plurality of electronic components 1 in order towards unanimity.
The following describes concrete experimental example.In the first embodiment, prepare and transmit following 5 kinds of chip-shaped electronic components 1.
The size of the electronic component of being prepared
(1)1005：L＝1.05mm、W＝0.5mm、T＝0.5mm
1608：L＝1.6mm、W＝0.8mm、T＝0.8mm
2012：L＝2.0mm、W＝1.25mm、T＝1.25mm
3216：L＝3.2mm、W＝1.6mm、T＝1.6mm
3225：L＝3.2mm、W＝2.5mm、T＝2.5mm
Prepare a plurality of above-mentioned 5 kinds of chip-shaped electronic components 1, make the magnetic force of first magnet do multiple variation, the speed of dividing with about 3m/ branch～7m/ transmits electronic component 1.Estimate in such cases transmission efficiency and the rotating effect of electronic component 1.So-called transmission efficiency is meant that can evaluation be sent to electronic component 1 downstream end of second transfer path one by one swimmingly from the upstream of first transfer path.So-called rotating effect is meant that can evaluation rotate also electronic component by magnetic force and correctly point toward the same.When actual evaluation, the electronic component by sorting the downstream that arrives second transfer path towards estimating.
The results are shown in following table 1.
[table 1]
As shown in Table 1, under the situation of the not enough 1G of magnetic force, well still rotating effect is poor for transmission efficiency.If magnetic force surpasses 1500G, transmission efficiency and rotating effect two sides are bad mostly, and this is too strong because of magnetic force, electronic component 1 is held, and side shifting downstream not, electronic component 1 is difficult to be used for the rotation that direction sorts.Magnetic force is under the situation of 1～1000G, and is different because of electronic component dimensions, can transmit electronic component 1 swimmingly and also can rotate in rotation path, and make its direction unanimity.
Certainly, the transmission efficiency of electronic component is not the size that only exists with ... the magnetic force of above-mentioned first magnet 21, also depend on the size of electronic component or constitute the ferromagnetic degree of the material of internal electrode, the lamination number of internal electrode etc., also the transfer rate that produces because of the forwarder of electronic component 1 is different, so be not that a kind of factor can determine.Promptly, result on the table 1 only shows, when transmitting above-mentioned 5 kinds of chip-shaped electronic components 1, just can improve transmission efficiency and rotating effect if adjust the magnetic force of first magnet 21, even the not enough 1G of magnetic force or surpass 1500G also can obtain Expected Results of the present invention according to component size, transfer rate.
Under above-mentioned 5 kinds of widely used component size, as long as magnetic force is taken as the above scope of 1G, just can positively make electronic component 1 towards unanimity; If magnetic force below 1000G, can transmit electronic component 1 reliably.If being 1005 situation lower magnetic force, component size is taken as 1～50G, component size is that 1608 situation lower magnetic force is taken as 100～200G, component size is that 2012 or 3216 situation lower magnetic force is taken as 300～500G, component size is under 3225 the situation, if magnetic force is taken as 700～1000G, can both easily obtain high transmission efficiency and rotating effect.
(second embodiment)
In the first embodiment, first magnet 21 is in the outside of guide wall 14b, and N is top, S below very very.
Different therewith, as shown in Figure 5, in second embodiment, the below the first magnet 21A is configured in rotation path 14 more particularly, is configured in second below of transmitting table top 14a.The top of this first magnet 21A is the N utmost point, is the S utmost point below.Therefore, generation magnetic line of force Z as shown in Figure 6.Owing to all produce the magnetic line of force Z that extends generally along above-below direction in guide wall 14b side and guide wall 14c side, thus the same with the situation of first embodiment, make electronic component 1 towards unanimity, the face direction of its internal electrode 3 is extended along the vertical direction.
Because the first magnet 21A is positioned at the second Width middle position below of transmitting table top 14a, so as shown in Figure 6, two places in guide wall 14b side and guide wall 14c side produce magnetic line of force, and the effect of magnetic line of force Z, the Z at two places just can make electronic component 1 rotate more reliably.Because the first magnet 21A is arranged on second below of transmitting table top 14a, so the operation of both sides that can the acceleration transfer path, the while can reduce the size of the Width of conveyer.
(the 3rd embodiment)
As shown in Figure 7, in the electronic component conveying equipment of the 3rd embodiment, except that the first magnet 21A, also be provided with another first magnet 21B.That is, in second embodiment, the first magnet 21A is arranged on second transmits the below of table top 14a, and in the 3rd embodiment, be provided with the first magnet 21B above it again.Like this, rotation path 14 is just by two first magnet 21A, 21B hold under the arm up and down.
As shown in Figure 8, the top of the first magnet 21B is the N utmost point, is the S utmost point below.
Like this, as shown in Figure 8, the first magnet 21B is arranged on the top of rotation path 14, also works from the magnetic line of force Z of the first magnet 21B, thus can allow electronic component 1 more positively rotate, and point toward the same.
With respect to the position of the first magnet 21A, adjust the position of the first magnet 21B, just can make the configuration variation of magnetic line of force.Therefore, electronic component 1 is rotated.
(other variation)
