Description

  The present invention relates to an electronic component transport apparatus that transports an electronic component by adsorbing it to a suction collet.

  As this type of conventional transfer device, for example, there is one described in Patent Document 1. The electronic component transport device disclosed in Patent Document 1 includes a lifting device for lifting and lowering a suction collet that sucks the electronic component, and a moving device for moving the suction collet in the horizontal direction.

  The lifting device holds the suction collet in the raised position when the suction collet moves in the horizontal direction by driving by the moving device. In addition, the lifting device lowers the suction collet when the suction collet sucks the electronic component or when the electronic component is placed on the placement portion (at the time of transfer).

Japanese Patent No. 4057643

  In the electronic component transport device described in Patent Document 1, there is a possibility that the electronic component may be damaged when the electronic component is sucked or placed. This is because the suction collet may collide with the upper surface of the electronic component with an impact load during suction, or the lead of the electronic component may be forcibly pressed against the placement surface during placement.

  Such a problem can be solved to some extent by reducing the lifting speed of the suction collet. However, if it does in this way, the time required for adsorption | suction and mounting of an electronic component will become long, and conveyance efficiency will fall.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide an electronic component transport device in which the electronic component is not damaged while keeping the electronic component transport efficiency high.

  In order to achieve this object, an electronic component transport apparatus according to the present invention includes a first delivery unit having an electronic component to be transported, a second delivery unit for transferring the electronic component, and an upper part of the electronic component. An adsorption collet having an adsorption surface opposite to the end surface formed at the lower end, a suction device for sucking air from an opening formed in the adsorption surface, and an upper side of the second delivery unit from above the first delivery unit A moving device that moves the suction collet in a horizontal direction, and the suction collet is a high gap in which a minute gap is formed between the upper end surface of the electronic component on the first delivery portion and the suction surface. The suction device is held by the moving device so as not to move in the vertical direction, and the suction device is arranged on the first delivery unit in a state where the suction collet is positioned above the first delivery unit. Electronic components Air suction is started at the suction amount adsorbed by the suction collet, and air suction is stopped in a state where the collet is positioned above the second delivery portion, and the first delivery is performed. A moving space in which the electronic component and the suction collet can move horizontally is formed between the part and the second delivery part.

  According to the present invention, in the above invention, the moving device includes a turntable that rotates intermittently, and the suction collet is arranged in parallel at equal intervals in the circumferential direction on the outer peripheral portion of the turntable. The delivery unit and the second delivery unit are configured by a plurality of processing devices disposed around the turntable.

  In the present invention, the electronic component is sucked up and sucked by the suction collet when the suction of the suction device is started while the suction collet is positioned above the first delivery portion. Further, in the present invention, the electronic component is released from the suction collet and dropped as the suction of the air by the suction device is stopped in a state where the suction collet is located above the second delivery portion. And placed on the second delivery unit.

  For this reason, the transport device according to the present invention does not need to raise and lower the suction collet when sucking and releasing the electronic component, and therefore, the suction collet may collide with the electronic component with an impact load as compared with the conventional transport device. In addition, the electronic component is not pressed against the mounting surface with an excessive pressing force. Moreover, according to the present invention, since the lifting time of the suction collet becomes zero, the transport time can be shortened as compared with the conventional transport device.

Therefore, according to the present invention, it is possible to provide a transport device for electronic components in which the electronic components are not damaged while keeping the transport efficiency of the electronic components high.
In addition, since the electronic component transport device according to the present invention does not require a lifting device for lifting and lowering the suction collet, the number of components is reduced as compared with the conventional transport device disclosed in Patent Document 1. Manufacturing cost can be reduced.

The drive device 13 is configured with a motor (not shown) as a power source, and intermittently rotates the turntable 3 by a predetermined angle around the vertical axis. This predetermined angle is an angle corresponding to 1 / N rotation, for example, when N suction collets 11 are arranged at equal intervals in the circumferential direction of the turntable 3.

In this embodiment, the turntable 3 and the driving device 13 constitute a moving device referred to in the present invention. The rotation angle, rotation speed, rotation timing, and the like of the turntable 3 when the drive device 13 drives the turntable 3 are controlled by the control device 10 described later.
A plurality of suction collets 11 are attached to the outer peripheral edge of the turntable 3. FIG. 1 is drawn with the number of the suction collets 11 reduced so that the configuration can be easily understood. As shown in FIGS. 9 to 13, in the actual transport device, a large number of suction collets 11 are provided on the turntable 3.

  A pneumatic device 16 is connected to the hose connection pipe 17 via an air hose 22. The pneumatic device 16 has a function of generating a negative pressure in the air holes 14 of all the suction collets 11 and the air holes 21a of the component delivery section 21, and a function of supplying air to the suction collets 11 moved to a predetermined position. And a function of supplying air to the air holes 21a of the component delivery section 21 at a predetermined timing. When air is supplied to the adsorption collet 11, the vacuum is broken, and the electronic component 12 adsorbed by the adsorption collet 11 is released and falls. In this embodiment, the pneumatic device 16 constitutes the suction device referred to in the present invention.

  Further, when air is sucked from the air hole 21a of the component delivery unit 21 by the pneumatic device 16, the electronic component 12 is sucked and held on the component delivery unit 21, and when air is supplied to the air hole 21a, a vacuum is generated. The electronic component 12 is opened by being destroyed. When the electronic component 12 sucked and held by the component delivery unit 21 is sucked by the suction collet 11, a negative pressure is generated in the suction collet 11 after the vacuum is broken in the component delivery unit 21 and the electronic component 12 is opened. Configuration is adopted.

  Hereinafter, a state in which the air holes 14 and 21 are under negative pressure is simply referred to as an “adsorption state”, and air is supplied to the adsorption collet 11 moved to a predetermined position or the air hole 21 a of the component delivery unit 21. The state in which the vacuum is broken is simply referred to as “open state”. The suction collet 11 that has moved to the predetermined position mentioned above refers to the suction collet 11 that has moved above the component delivery section 21 of the processing apparatus to which the electronic component 12 is transferred (position where the component is released).

  As shown in FIG. 2, the pneumatic device 16 according to this embodiment includes a vacuum generator 24 connected to all the adsorption collets 11 by a first air passage 23 for each adsorption collet having the air hose 22; A second air passage 26 connecting the intermediate portion of the first air passage 23 and the air pressure source 25, a first electromagnetic valve 27 provided in the second air passage 26, and the vacuum generator 24 A third air passage 28 for connecting the air passage 21 to the air hole 21a of the component delivery portion 21, a fourth air passage 29 for connecting the intermediate portion of the third air passage 28 and the air pressure source 25, A second electromagnetic valve 30 provided in the fourth air passage 29 is provided. The first air passage 23 has a structure in which the adsorption collet 11 can move as the turntable 3 rotates while maintaining a state where air is sucked from the adsorption collet 11. The first and second solenoid valves 27 and 30 according to this embodiment are closed in a non-excited state and opened by being excited.

  The second air passage 26 and the first electromagnetic valve 27 are provided in the same number as the processing device that receives the electronic component 12, and do not move to the base 2 by a support system different from the turntable 3. So that it is supported. The second air passage 26 is formed so as to communicate only with the first air passage 23 connected to the suction collet 11 moved to a position where the electronic component 12 is opened. Further, the third and fourth air passages 28 and 29 and the second electromagnetic valves 30 are provided in the same number as all the processing apparatuses on which the electronic component 12 is placed.

Operations of the vacuum generator 24 and the first and second electromagnetic valves 27 and 30 are controlled by the control device 10. The configuration of the pneumatic device 16 is not limited to the configuration shown in this embodiment, and can be changed as appropriate.
The vacuum generator 24 is configured to suck air so that a predetermined amount of intake air is obtained. The amount of intake air becomes negative in the air hole 14 of the adsorption collet 11 at a predetermined vacuum pressure, and when the negative pressure acts on the electronic component 12, the electronic component 12 is lifted to the adsorption collet 11. The amount to be absorbed is set.

  As shown in FIGS. 1 and 9 to 13, various processing devices arranged around the turntable 3 include a parts feeder 4, a correction device 5, an energization inspection device 6, a marking device 7, and an image inspection. An apparatus 8 and a taping apparatus 9. As shown in FIG. 9, these devices are fixed to the base 2 while being placed on the base 2. Operations of these processing devices 4 to 9 and operations of the turntable driving device 13 and the pneumatic device 16 described above are controlled by the control device 10.

  As shown in FIG. 14, the control device 10 includes a moving device control unit 31 for controlling the operation of the moving device (turntable driving device 13) and a suction device control for controlling the operation of the pneumatic device 16. Unit 32, parts feeder control unit 33 for controlling the operation of parts feeder 4, correction device control unit 34 for controlling the operation of correction device 5, and energization for controlling the operation of energization inspection device 6 Control the operation of the inspection device control unit 35, the marking device control unit 36 for controlling the operation of the marking device 7, the image inspection device control unit 37 for controlling the operation of the image inspection device 8, and the operation of the taping device 9. And a taping device control unit 38.

  The parts feeder 4 is for supplying the electronic component 12, and in this embodiment is constituted by a bowl feeder. As shown in FIG. 3, the electronic component supply unit 41 of the parts feeder 4 includes a guide rail 42 and a shooter main body 43 for sending the electronic components 12 in a line in one direction (right direction in FIG. 3), And a slider 45 for moving the electronic components 12 positioned at the downstream end in the direction to the component supply position 44 one by one.

The guide rail 42 has a predetermined upper surface of the electronic component 12 so that the electronic component 12 can be sent in a state where the electronic component 12 is correctly placed on the shooter main body 43 (a state in which the electronic component 12 is not greatly inclined). They are formed so as to face each other with a gap d1 (see FIG. 3B).
The slider 45 constitutes the component delivery section 21 in the parts feeder 4 and constitutes the first delivery section referred to in the present invention.

  The slider 45 is horizontally between a component receiving position 46 adjacent to the shooter body 43 {see FIG. 3A) and a component supply position 44 located below the suction collet 11 {see FIG. 3B}. The structure which reciprocates is taken. As shown in FIG. 3B, the vertical position of the slider 45 is positioned on the electronic component 12 on the slider 45 and the position above the electronic component 12 when the electronic component 12 is placed and moved to the component supply position 44. The adsorbing collet 11 is positioned so as to form a gap d. A gap d1 between the guide rail 42 and the electronic component 12 is formed to be wider than the gap d between the electronic component 12 on the slider 45 and the suction collet 11. Although not shown, the slider 45 is formed with an air hole in the same manner as the component delivery unit 21 shown in FIG. 2, and the pneumatic device 16 is connected through the air hole. .

  As shown in FIG. 3A, the parts feeder 4 sends the electronic component 12 in a state where the slider 45 is positioned at the component receiving position 46, and transfers the electronic component 12 onto the slider 45. The electronic component 12 is attracted and held by the slider 45. The slider 45 moves to the component supply position 44 after attracting and holding the electronic component 12 in this way {see FIG. 3B}. At this time, the control device 10 brings the suction collet 11 into the “opened state” by energizing the first electromagnetic valve 27 of the pneumatic device 16, and rotates the turntable 3 to bring the suction collet 11 above the component supply position 44. Move.

The height of the upper end of the electronic component 12 on the slider 45 is always lower than the suction surface 15 of the suction collet 11 in order to coincide with the height when the electronic component 12 is sent from the guide rail 42. For this reason, when the suction collet 11 moves above the component supply position 44 due to the rotation of the turntable 3, the electronic component 12 on the slider 45 is not hit from the side.
The control device 10 switches the slider 45 to the “open state” and switches the suction collet 11 to the “suction state” while the slider 45 is located at the component supply position 44.

  That is, when the suction collet 11 is positioned above the electronic component 12 and the slider 45 is in the “open state”, the suction of the electronic component 12 is started at the suction amount by which the electronic component 12 is attracted to the suction surface 15. . Thus, the electronic component 12 on the slider 45 is adsorbed to the adsorbing collet 11 as the adsorbing collet 11 enters the “adsorbing state” {see FIG. 3C}. Thereafter, the control device 10 rotates the turntable 3 by a predetermined angle at a predetermined time, and directs the suction collet 11 positioned above the slider 45 toward the next correction device 5 (substantially the paper surface of FIG. 3). (In an orthogonal direction) {see FIG. 3D}.

The correction device 5 is for correcting the suction position of the electronic component 12 with respect to the suction collet 11, the angle around the vertical axis of the electronic component 12, and the like.
As shown in FIG. 4, the correction device 5 according to this embodiment includes an open / close clamp 51 having a structure for holding the electronic component 12 from the side. Although not shown in FIG. 4, the clamp 51 is configured to correct the horizontal position of the electronic component 12 and the angle around the vertical axis by sandwiching the electronic component 12 from four directions. .

As shown in FIG. 4A, the clamp 51 is positioned so that the electronic component 12 sucked by the suction collet 11 can pass over the clamp 51 in the open state.
As shown in FIG. 4A, the correction device 5 waits for the electronic component 12 sent from the parts feeder 4 side with the clamp 51 opened. Between the clamp 51 in the open state and the slider 45 at the component supply position of the parts feeder 4 described above, a moving space S1 in which the electronic component 12 and the suction collet 11 can move horizontally {FIG. 3 (D) and 4 (A)} is formed. For this reason, the electronic component 12 and the suction collet 11 move from the parts feeder 4 to the correction device 5 without being blocked by other members.

  The clamp 51 holds the electronic component 12 after the electronic component 12 is positioned upward {see FIGS. 4B and 4C}. On the other hand, the suction collet 11 is in an “open state” as the clamp 51 holds the electronic component 12. For this reason, the clamp 51 will clamp the electronic component 12 in the state released from the suction collet 11, and the position and angle of the electronic component 12 can be corrected.

The suction collet 11 enters the “suction state” after the correction operation by the correction device 5 is completed. When the clamp 51 is opened in this state, the electronic component 12 is attracted to the suction collet 11. That is, the clamp 51 according to this embodiment serves as both the first delivery portion and the second delivery portion referred to in the present invention.
After the electronic component 12 is attracted to the suction collet 11 in this way, the control device 10 rotates the turntable 3 by a predetermined angle at a predetermined time, and then moves the suction collet 11 positioned above the clamp 51 to the next. It is moved toward the energization inspection device 6.

  The energization inspection device 6 is for actually energizing the electronic component 12 to measure or inspect the electrical characteristics of the electronic component 12. As shown in FIG. 5, the energization inspection device 6 includes an electrode 52 that contacts the lead 12 b of the electronic component 12. As shown in FIG. 5 (A), the electrode 52 includes a standby position where the electronic component 12 sucked by the suction collet 11 can pass upward, and a lead of the electronic component 12 as shown in FIG. 5 (C). The structure which raises / lowers between the inspection positions which contact 12b from the downward direction is taken.

  As shown in FIG. 5A, the energization inspection device 6 waits for the electronic component 12 sent from the correction device 5 side with the electrode 52 moved to the standby position. Between the electrode 52 in the standby position and the clamp 51 of the correction device 5 described above, a moving space S2 in which the electronic component 12 and the suction collet 11 can move horizontally {FIGS. 4C and 5A]. Reference} is formed. For this reason, the electronic component 12 and the suction collet 11 move from the correction device 5 to the energization inspection device 6 without being blocked by other members.

In the state where the electronic component 12 is positioned above the electrode 52, the energization inspection device 6 raises the electrode 52 to the inspection position, and energizes the electronic component 12 to perform measurement and inspection. The energization inspection device 6 lowers the electrode 52 to the standby position after the end of the measurement or inspection.
The control device 10 keeps the suction collet 11 in the “sucking state” whenever the electronic component 12 is on the energization inspection device 6. That is, the electronic component 12 is not delivered to the energization inspection device 6. Further, the control device 10 rotates the turntable 3 by a predetermined angle at a predetermined time after the measurement and inspection operations by the energization inspection device 6 are completed, and then moves the suction collet 11 positioned above the electrode 52 to the next. It is moved toward the marking device 7.

The marking device 7 is for entering predetermined symbols, characters, etc. on the package portion 12a of the electronic component 12. As shown in FIGS. 6 and 11, the marking device 7 includes a support member 53 for delivering the electronic component 12 and a marking device main body 54 for writing symbols, characters, and the like on the electronic component 12. ing.
As shown in FIG. 6, the support member 53 is formed with a recessed portion 55 that opens upward, and is attached to the outer peripheral portion of the marking device turntable 56 as shown in FIG. 11. Although not shown, the support member 53 is formed with air holes in the same manner as the component delivery section 21 shown in FIG. 2, and the pneumatic device 16 is connected through the air holes. Yes.

As shown in FIG. 6A, the height of the upper end portion of the support member 53 is a height at which the suction collet 11 can pass above the support member 53 with the electronic component 12 being sucked. As shown in FIG. 6C, the height is set such that a gap d is formed between the electronic component 12 accommodated in the recessed portion 55 and the suction collet 11.
As shown in FIG. 6C, the recessed portion 55 is formed in a shape and size that allows the lower end portion of the electronic component 12 to be fitted in a loosely fitted state.

As shown in FIGS. 6A to 6C, the electronic component 12 moves above the support member 53 while being sucked by the suction collet 11, and the suction collet 11 is positioned above the support member 53. In the state where it is switched to “open state”, it falls into the recessed portion 55 and is accommodated. The electronic component 12 is sucked and held by the support member 53 when the support member 53 is switched to the “sucking state”.
Between the support member 53 and the electrode 52 of the above-described current inspecting device 6, a moving space S3 in which the electronic component 12 and the suction collet 11 can move horizontally {see FIG. 5C and FIG. 6A. } Is formed. For this reason, the electronic component 12 and the suction collet 11 move from the energization inspection device 6 to above the support member 53 without being blocked by other members.

  As shown in FIG. 11, the support members 53 are arranged at equal intervals in the circumferential direction of the marking device turntable 56. The turntable 3 rotates intermittently so that the plurality of support members 53 sequentially move below the suction collet 11 when driven by the driving device 57.

The marking device main body 54 is disposed at a position separated from the turntable 3 having the suction collet 11 with the marking device turntable 56 interposed therebetween.
The electronic component 12 marked by the marking device body 54 moves below the suction collet 11 as the turntable 56 rotates. The suction collet 11 maintains the “open state” until the electronic component 12 moves downward, and enters the “suction state” when the electronic component 12 is positioned downward and the support member 53 is switched to the “open state”. Switched.

By switching the suction collet 11 to the “suction state”, the electronic component 12 on the support member 53 is sucked to the suction collet 11. That is, the support member 53 of the marking device 7 according to this embodiment serves as both the first delivery portion and the second delivery portion referred to in the present invention.
After the electronic component 12 on the support member 53 is sucked by the suction collet 11 in this way, the control device 10 rotates the turntable 3 by a predetermined angle at a predetermined time, and is positioned above the support member 53. The suction collet 11 is moved toward the next image inspection apparatus 8.

  The image inspection apparatus 8 is for confirming the presence / absence of the electronic component 12 sucked by the suction collet 11 and the position of the electronic component 12 with respect to the suction collet 11. As shown in FIG. 7, the image inspection apparatus 8 has a configuration in which the electronic component 12 sucked by the suction collet 11 is photographed substantially horizontally from the outside in the radial direction of the turntable 3.

  Between the image inspection apparatus 8 and the support member 53 of the marking apparatus 7 described above, a moving space S4 in which the electronic component 12 and the suction collet 11 can move horizontally {see FIG. 6C and FIG. 7A. } Is formed. For this reason, the electronic component 12 and the suction collet 11 move from the marking device 7 to the side of the image inspection device 8 without being blocked by other members.

The control device 10 keeps the suction collet 11 in the “sucking state” until the electronic component 12 moves from the marking device 7 described above to the taping device 9 described later via the image inspection device 8. That is, the electronic component 12 is not delivered to the image inspection apparatus 8.
Further, after the inspection operation by the image inspection device 8 is completed, the control device 10 rotates the turntable 3 by a predetermined angle at a predetermined time, and the suction collet 11 located on the side of the image inspection device 8 is moved. It moves toward the next taping device 9.

  The taping device 9 is for storing the electronic component 12 in the carrier tape 61 (see FIG. 8). The taping device 9 positions the embossed portion 62 of the carrier tape 61 below the suction collet 11, and after the electronic component 12 is transferred to the embossed portion 62, the carrier tape 61 is fed by one pitch, and the adjacent embossed portion 62 is moved. The suction collet 11 is moved below.

The height of the component transfer portion 63 (see FIG. 13) for transferring the electronic component 12 onto the carrier tape 61 in the taping device 9 is formed above the carrier tape 61 so that the electronic component 12 can be moved from the side. Yes. The component transfer unit 63 constitutes a second delivery unit referred to in the present invention.
Between the component transfer part 63 of the taping device 9 and the image inspection device 8 described above, a moving space S5 in which the electronic component 12 and the suction collet 11 can move horizontally {FIG. 7C and FIG. ) Reference} is formed. Therefore, the electronic component 12 and the suction collet 11 move from the image inspection apparatus 8 to above the component transfer unit 63 (carrier tape 61) without being blocked by other members.

The control device 10 places the suction collet 11 in the “open state” while the suction collet 11 is located above the carrier tape 61, and drops the electronic component 12 from the suction collet 11 into the embossed portion 62.
The control device 10 controls the operations of the turntable 3 and the pneumatic device 16 as shown in the flowchart of FIG. That is, first, as shown in step S1, the control device 10 determines whether or not each suction collet 11 is positioned above the first delivery unit. In this embodiment, the first delivery portion is a slider 45 of the parts feeder 4, a clamp 51 of the correction device 5, and a support member 53 of the marking device 7.

  Next, in step S2, the control device 10 sets the pneumatic device 16 to the ON state, that is, the “suction state” for the suction collet 11 positioned above the first delivery unit. On the other hand, the control device 10 determines whether or not the suction collet 11 determined not to be located above the first delivery unit is located above the second delivery unit in step S3.

  In this embodiment, the second delivery portion is a clamp 51 of the correction device 5, a support member 53 of the marking device 7, and a component transfer portion 63 of the taping device 9. For the suction collet 11 positioned above the second delivery unit, in step S4, the pneumatic device 16 is turned off, that is, "open state". The control device 10 determines whether or not the processing is completed in all the processing devices in step S5 after the electronic component 12 is adsorbed to the adsorption collet 11 or the electronic component 12 is released from the adsorption collet 11. After the process is completed, the turntable 3 is rotated by a predetermined angle (step S6).

  In the transport device 1 configured as described above, the electronic component 12 is started in response to the start of air suction by the pneumatic device 16 in a state where the suction collet 11 is positioned above the first delivery unit. Is sucked up and sucked into the suction collet 11. Further, in the transport device 1, the electronic component 12 is attached to the suction collet 11 when the suction of air by the pneumatic device 16 is stopped in a state where the suction collet 11 is positioned above the second delivery unit. And is dropped and placed on the second delivery section.

  For this reason, since this conveyance apparatus 1 does not need to raise / lower the adsorption collet 11 in performing the adsorption | suction and opening | release of the electronic component 12, compared with the conventional conveyance apparatus, the adsorption collet 11 does not collide with the electronic component 12. At the same time, the electronic component 12 is not pressed against the placement surface with an excessive pressing force. Moreover, according to this embodiment, since the raising / lowering time of the suction collet 11 becomes zero, the conveyance time can be shortened as compared with the conventional conveyance device.

Therefore, according to this embodiment, it is possible to provide the electronic component transport apparatus 1 in which the electronic component 12 is not damaged while the transport efficiency of the electronic component 12 is kept high.
Moreover, since the conveying apparatus 1 by this embodiment does not require the raising / lowering apparatus for raising / lowering the adsorption | suction collet 11, it reduces a component number compared with the conventional conveying apparatus currently disclosed by patent document 1. FIG. Manufacturing cost can be reduced.

In addition, the transport apparatus 1 according to this embodiment includes a turntable 3 that rotates intermittently, and an adsorption collet 11 that is arranged in parallel at equal intervals in the circumferential direction on the outer periphery of the turntable 3. A first delivery unit that receives the electronic component 12 and a second delivery unit that transfers the electronic component 12 are configured by a plurality of processing devices disposed around the turntable 3.
For this reason, according to this embodiment, it is possible to provide the rotary electronic component transport device 1 in which the transport efficiency of the electronic component 12 is increased and the electronic component 12 is not damaged.

The electronic component 12 conveyed by the conveying device 1 shown in the above-described embodiment has a weight of 3 g or less, and the protruding length of the lead 12b protruding downward from the bottom surface of the package portion 12a is 0.1 mm. It is as follows. Moreover, the vacuum pressure when adsorbing the electronic component 12 to the adsorption collet 11 was −40 to −60 kpa (absolute vacuum was set to −101.3 kpa).
A gap d between the slider 45 of the electronic component supply unit 41 and the suction collet 11 was set to 0.2 mm.
The gap d between the electronic component 12 held on the support member 53 of the marking device 7 and the suction collet 11 was set to 0.4 mm.
These numerical values are merely examples, and can be changed as appropriate in accordance with the type of the electronic component 12 to be processed.
