Embodiment

Fig. 1 is the decomposition diagram of structure that the major part of the tape feeder in the embodiment of the invention is shown.The feed mechanism that is used for carrier band 2 comprises sprocket wheel 1, and, with etc. the pin 3 that is formed on the periphery of sprocket wheel 1 of pitch engage with feed hole 4, feed hole 4 on the length direction of carrier band 2 with etc. pitch be formed on the carrier band 2.When sprocket wheel 1 carries out calibration rotation (index rotation) with the anglec of rotation of confirming, the carrier band 2 that engages with pin 3 in the longitudinal direction with etc. pitch presented sequentially that (arrow labeled a).In the tape feeder of this embodiment, for the rotation of calibration each time of sprocket wheel 1, the pitch of presenting of carrier band 2 is set at 4mm.

Carrier band 2 in the longitudinal direction with etc. pitch hold a plurality of elements 5.The type that depends on element 5 is used to have the different carrier bands that holds pitch 2.Yet, be set under the condition of 4mm in the pitch of presenting of tape feeder, regardless of the type of element 5, hold the integral multiple that pitch all is set at 4mm.Therefore, holding under the situation that pitch is 4mm, for example, the presenting pitch and can be set at of the carrier band 2 of sprocket wheel 1 calibration rotation each time, i.e. 4mm with to hold pitch identical.Holding under the situation that pitch is 12mm the presenting pitch and can be set at 12mm of the carrier band 2 of per three calibration rotation of sprocket wheel 1.

Lid 6 is the members that are used for covering from the top carrier band 2.Lid 6 is by (two holes 7 that arrow labeled a) is arranged on the rear portion are attached to the side of the main body 8 of tape feeder pivotally on the tape feed direction; And cover 6 and can be around two holes 7 rotate to open or close through the engage sides of fore two hooks 9 and the main body 8 of tape feeder being set, making.When tape feeder was in the work, lid 6 was closed top and the sidepiece with covering carrier band 2, thereby regulated the attitude of presenting of carrier band, and when feed hole 4 engaged with the pin 3 of sprocket wheel 1 under occasions such as exchange carrier band 2, lid 6 was opened, so that the operator is approaching easily.

The component pick-up opening 10 that is used for taking out the element 5 that is contained in carrier band 2 is formed on and covers 6 approximate centre, is through to the back side from the surface.Being used for shutter 11 that on tape feed direction top ground closure member picks up opening 10 is arranged on and covers 6 the back side.Shutter 11 usefulness screws 13 are fastened to and are formed on the elongated orifices of covering in 6 12, and can under the state that screw 13 becomes flexible, slide along elongated orifices 12.Slippage through according to the size adjustment shutter of element 5 can change the length of component pick-up opening 10 on the tape feed direction.With etc. a plurality of elements 5 of being contained in the carrier band 2 of pitch will sequentially pick up from component pick-up opening 10 by devices such as nozzles.

Fig. 2 is the plane graph that the structure of component pick-up opening and peripheral region thereof is shown.Regardless of the size of element 5, the position p of nozzle pickup device 5 fixes with respect to component pick-up opening 10.Usually, the state that keeps is stablized thereby keep element in the center of nozzle suction element (center of shape) after picking up, and, need the operator that the center (center of its shape) of element 5 on the tape feed direction aimed at take-off location p.The symmetrical marker 15 that is arranged on the sidepiece of component pick-up opening 10 is to be used for the mark of the centralized positioning that is in the element 5 under the state that is accommodated in carrier band 2 to take-off location p.The operator is based on the location of being indicated executive component 5 by the vision shown in the symmetrical marker 15.The location that carrier band 2 comes executive component 5 is presented in the anglec of rotation and front and back through regulating sprocket wheel 1, and the anglec of rotation of sprocket wheel 1 when element 5 has been positioned will be the benchmark of calibration rotation.

Symmetry marker 15 comprises that (arrow labeled is the pattern of the position p1 line symmetry that will locate of institute a), and these patterns carry out visible change with definite interval on the tape feed direction for center about element 5.Though like exemplary illustrate among Fig. 2; Symmetry marker 15 illustrates with the pattern of gray scale, and the colourity of this gray scale is 0, and brightness is with each interval variation of confirming; But the tone of symmetrical marker 15, brightness and colourity can change separately, and perhaps their combination also can change.Optionally, symmetrical marker 15 can comprise have with the order that increases or with the pattern (Fig. 3 (a)) of the numeral of the order symmetric arrangement that reduces, have the difform symbol of symmetric arrangement and the pattern of figure (Fig. 3 (b)) or painted areas 16 bases with the distance of position p1 stepping pattern (Fig. 3 (c)).

Have mark or element has under the situation such as the regular shape of rectangular shape at the center of element 5; When the operator carries out the location of element 5; Because can easily hold the center, so directly (arrow labeled a) the position p1 that will locate of institute is aimed at regard to so difficult on the tape feed direction with the center of element 5 with the center of element 5.And, when the type of element 5 does not have change and shutter 11 to be in stationary state, because the shape of opening is constant, so can utilize the shape of component pick-up opening 10 to carry out the location of element 5 as indicateing arm.Yet, have under the erose situation as shown in Figure 2 at element 5, be difficult to the assurance center, and when the shape of component pick-up opening 10 often changes, can not the shape of opening be used as indicateing arm.

Symmetry marker 15 is to be used for mark that the center of element 5 is directly aimed at center p1, and the while also is the position p2 that is used to consider the end opposite (front-end and back-end) of element 5 on the tape feed direction, p3 and the mark of setting element 5.Particularly; When the brightness corresponding to the front position p2 of element 5 that is positioned to symmetrical marker 15 when element 5 can equal corresponding to the brightness of back-end location p3; As shown in Figure 2; Can realize making the state of the centralized positioning of element 5 to the center p1 of symmetrical marker 15, that is, and with element 5 centerings.Can easily hold position p2, the p3 of the end opposite of element 5 by the center, therefore,, reduce setting element 5 required burdens and become possibility, thereby but the enhanced positioning accuracy also be the phase through using symmetrical marker 15.

The interval that the characteristic (for example, brightness) of symmetrical marker 15 is changed is more little, and the location of element 5 just can be accurate more.Yet, consider, under the situation that the quantity of the kind of the color that will use and symbol increases, visually distinguish their difficulties that becomes.Therefore, consider the environment of size of component, use etc., marker can suitably be set the interval that can the most easily carry out the location for.In this case, can add the aid mark that is used for further cutting apart each interval.And, can comprise being arranged on the symmetrical marker 15 that covers on 6 extraly the pattern (Fig. 3 (d)) that the aperture area basis that perhaps can comprise component pick-up opening 10 and the distance of position p1 change as the mark of the indicateing arm that is used for setting element 5.
