Abstract

(57) [Summary] [Purpose] The purpose of this invention is to prevent the chip from breaking when the nozzle centers the chip after suctioning it when mounting the chip on a circuit board. [Structure] This invention consists of a chip mounting machine in which a contact portion is provided on a nozzle and a finger body or on an opposing finger body.

Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a chip mounting machine for mounting chips on a substrate.

[Conventional technology]

The conventional technology had the configuration shown in FIGS. 3 and 4. In the figure, 5 indicates a chip component supply device such as a pallet or a tape feeder for transporting the chip 2. (not shown) and attach it to the board (not shown) placed on the table. It's a nozzle. The nozzle 5 has its upper part attached to an XY table (not shown). It can move freely in the X and Y directions. 6 is a finger body, which faces each other from the X direction and the Y direction with the nozzle 5 in between. This finger body 6 has an arm part 6A and a finger part 6B. Consisting of This means that the nozzle 5 feeds the chips 2 onto a pallet, tape feeder, etc. After being picked up from the chip supply device (not shown), the chip 2 comes to the center of the nozzle 5. This is to correct misalignment. As shown in FIG. 4, the two finger bodies 6, 6 move in the direction of the nozzle 5, and the fin The gar parts 6B and 6B sandwich the tip 2 from both sides to prevent the tip 2 from shifting from the nozzle 5. If so, correct it to the appropriate position. Do this from both the X and Y directions.

[Problem that the idea aims to solve]

However, in the conventional technology, when correcting the misalignment of the chip 2, the finger portion Since 6B and 6B directly hit the chip 2 from both sides, the impact force causes the chip 2 to crack. There was something that happened.

[Means to solve the problem]

The nozzle that sucks the chip and the finger part facing each other and the finger part facing downwards. It consists of a finger body consisting of an arm section that is held toward the nozzle. A tip that corrects the misalignment of the tip by moving it in the direction and making contact with the tip. In the mounting device, when correcting misalignment, the finger is placed at a position wider than the size of the chip. The abutment part that stops the part is attached to the nozzle and the finger body, or to the finger body opposite to the nozzle. Form.

[Effect] When correcting the misalignment of the chip, the fingers do not pinch the chip from both sides.

[Example of idea]

In FIG. 1, 1 is the nozzle of this invention. At its tip, as shown in the figure. Two step portions 1A and 1B are provided. 3 is a fiftee that corrects positional deviation from the X direction. It is a finger body and consists of an arm part 3A and a finger part 3B. Finger part 3B is provided with a contact portion 3C as shown in FIG. 1, and this contact portion 3C and the stepped portion 1B of the nozzle 1 are This contact prevents the finger portion 3B from moving beyond a certain level in the nozzle direction. 4 is a finger body that corrects misalignment of the chip 2 from the Y direction; It consists of a section 4A and a finger section 4B. The finger portion 4B has an abutment as shown in FIG. A portion 4C is provided, and the contact portion 4C and the stepped portion 1A of the nozzle 1 are in contact with each other to prevent the nozzle from turning over a certain level. Prevents movement in the direction. When correcting the positional deviation of the chip 2 in the X direction with this mounting device, the The finger bodies 3, 3 move toward the nozzle 1 in the same manner. At this time, chip 2 is on the right side in the diagram. If the finger part 3B on the right side hits the chip 2, it will cause the chip 2 to Move it to the left. As shown in the figure, contact parts 3C, 3C of finger parts 3B, 3B The distance W between the contact parts 3C and 3C when they respectively contact the step part 1B of the nozzle 1 is , is larger than the size L of chip 2, so chip 2 is not pinched from both sides, and the chip is P2 will not break. If chip 2 is shifted to the left in the figure, The ringer 3B hits the chip 2 and moves the chip 2 to the right. In this case as well, The contact parts 3C and 3C of the finger parts 3B and 3B are in contact with the step part 1B of the nozzle 1, respectively. Since the distance W between the contact parts 3C and 3C is larger than the size L of the chip 2, the chip The chip 2 will not be pinched from both sides, and the chip 2 will not be broken. Contact part 3C, When the chip 3C hits the stepped part 1B of the nozzle 1, the chip 2 is placed in the W between the contact parts 3C and 3C. is present from the beginning, the finger portions 3B, 3B do not contact the chip 2. Similarly, the misalignment of the chip 2 is also corrected in the Y direction as shown in Figure 2. . When the finger bodies 4, 4 are moved in the direction of the nozzle 1, the tip 2 moves to the left and right in the figure. If it is misaligned, it will be corrected to the appropriate position. At this time, finger parts 4B, 4B The abutting parts 4C and 4C abut on the stepped part 1A of the nozzle 1, respectively, and beyond that, the nozzle side The distance Z between the contact parts 4C and 4C is smaller than the size R of the chip 2 in the Y direction. Since it is large, you won't have to pinch it from both sides and break chip 2. Further, in the above embodiment, the step portions 1A and 1B are provided at the tip of the nozzle 1, and the fins are When the gar parts 3B and 4B and the stepped parts 1B and 1A of the nozzle 1 come into contact with each other, Although the spacing between the opposing fingers is larger than the tip, the opposing finger parts A stepped portion is provided on each side so that when the finger portion and the nozzle come into contact, the opposing fingers A similar effect can be obtained even if the spacing between the two parts is made larger than the tip. Furthermore, make sure that the arm part of the finger body is in contact with the nozzle, so that the arm part and nozzle Make sure that the distance between the fingers when the chips touch is larger than the size of the chip. It's okay. In the above embodiment, the joint portion was provided between the nozzle and the finger pair, but the A contact part is provided on the finger body, and the contact part is designed to ensure that the finger part pinches the chip from both sides. The contact portion may be prevented.

【effect】

The fingers will not hit the chip from both sides, so the chip will not break. disappears.
