Problems solved by technology

In this component mounting machine, when the support pin is automatically replaced, the support pin is held by a chuck mounted on the mounting head to perform reloading. However, if the support pin to be held is stepped on a foreign object or the like When tilted, the support pin may fail to be held or the chuck may interfere with the support pin and be damaged.
In addition, if the automatically replaced support pins are stepped on foreign objects or the like on the support plate and tilted, the effect of supporting the circuit board from below may not be sufficiently obtained, or components mounted on the lower surface side of the circuit board may be damaged by the support pins. interference

Embodiment 1

[0027] based on Figure 1 to Figure 6 Example 1 will be described.

[0028] First, based on figure 1 and figure 2 The structure of the support pin 11 will be described.

[0029] A base portion 12 that supports the support pin 11 in a vertical state is provided on the lower side of the support pin 11 . The base portion 12 is provided with a magnet 13 for holding the support pin 11 on a support plate 26 described later by magnetic force.

[0030] In the outer periphery of the support pin 11, three or more places (four places in this embodiment 1) lowered by a predetermined size from the upper end are provided at equal angular intervals (90° intervals in this embodiment 1) respectively. There is a raised portion 14 . Each boss 14 is formed in the same shape and size, and is also used as an engaging holder (not shown) that is replaceably attached to a mounting head (not shown) of a component mounting machine to snap into place. The engaging protrusion of the support pin 11 ...

Embodiment 2

[0045] Next, use Figure 7 and Figure 8 Example 2 will be described. However, the same reference numerals are assigned to the parts that are substantially the same as those in the first embodiment described above, and the description thereof will be omitted or simplified, and the different parts will be mainly described.

[0046] In the above-mentioned first embodiment, one marking portion 15 is provided on the upper surface of each raised portion 14, but Figure 7 and Figure 8 In the illustrated Example 2, a plurality of marking portions 15a, 15b are provided on the upper surface of each protrusion portion 14 . A plurality of marking portions 15a, 15b of each protrusion 14 are located on a plurality of concentric circles centered on the axis of the support pin 11, and for all protrusions 14, each marking portion 15a, 15b is separated from the outer peripheral surface of the support pin 11. The distances are set to the same distance. exist Figure 7 and Figure 8 In t...

Embodiment 3

[0053] Next, use Figure 9 and Figure 10 Example 3 will be described. However, the same reference numerals are attached to the parts that are substantially the same as those in Embodiments 1 and 2 above, and the description thereof will be omitted or simplified, and the different parts will be mainly described.

[0054] In the above-mentioned Embodiments 1 and 2, one or more marking portions 15 are respectively provided on the upper surface of each raised portion 14, but in Figure 9 and Figure 10 In the illustrated embodiment 3, the gradation portion 18 whose shade or color changes continuously or in stages is provided on the upper surface of each protruding portion 14 as it moves away from the outer peripheral surface of the support pin 11 . This gradation portion 18 is used as a portion indicating information on the length from the outer peripheral surface of the support pin 11 (or the length to the tip of the boss portion 14 ). The gradation portion 18 can be provide...

Abstract

Provided is a back-up pin state confirmation system for a component mounting apparatus having functionality to automatically replace a back-up pin (11) that supports from below a circuit substrate (20) on which a component is mounted. A protrusion (14) is provided at each of three or more locations on an outer periphery of the back-up pin below the upper end thereof by a predetermined distance. An image processing device (37) performs image recognition in which an image captured from above, including the back-up pin with the protrusions at three or more locations in the view field of a camera (32), is processed to acquire information about the length of a portion of each of the protrusions that is not hidden by the upper end portion of the back-up pin, and determines whether the back-up pin has a predetermined angle or more of inclination on the basis of the result of image recognition.

Description

technical field [0001] This specification discloses a technology related to a support pin state confirmation system of a component mounting machine equipped with a function of automatically replacing support pins for supporting a circuit board on which components are mounted from below. Background technique [0002] Since component mounting substrates have become thinner in recent years, they are prone to bending. Therefore, when components are mounted on a circuit board by a component mounting machine, the circuit board is supported from below by support pins to prevent the circuit board from bending. In addition, as described in Patent Document 1 (International Publication WO2015 / 040755), there is a component mounting machine that changes the arrangement of support pins or changes the support pins according to the type or size of the circuit board. type, equipped with the function of automatic replacement of support pins. In this component mounting machine, when the suppo...
