The first inspection line 603 may include: first transfer units 610 and 620 capable of transferring the article 101 in a predetermined direction; a first inspection unit 650 capable of inspecting the article 101; and a first converting part 630 which enables the first side surface of the article 101 to be arranged so that the first inspection part 650 can inspect. The second inspection line 605 may include: second transfer units 680 and 690 capable of transferring the article 101 in a predetermined direction; a second inspection unit 660 capable of inspecting the article 101; and a second switching unit 640 that allows the second inspection unit 660 to inspect the second side surface of the article 101. The first and second inspection lines 603 and 605 are arranged in parallel and have substantially the same configuration. Therefore, the first inspection line 603 will be described in detail below, and the second inspection line 605 will not be described in redundant detail with respect to the components that are substantially the same as or similar to the first inspection line 603.
In this embodiment, the first transfer portions 610 and 620 and the second transfer portions 680 and 690 may include one or more article transfer devices capable of transferring the article 101 in a predetermined direction. For example, as the article transfer device, various devices including a pulley and a belt interlocked therewith can be used. The first transfer portions 610 and 620 may include a first front transfer portion 610 disposed in front of the first converting portion 630 and a first rear transfer portion 620 disposed behind the first converting portion 630. The first front transfer portion 610 may include: a first front transfer pulley 613 connected to the front frame 611; a first front transfer belt 615 linked with the first front transfer pulley 613; and a first forward transfer driving unit 617 for driving the first forward transfer pulley 613 and the first forward transfer belt 615. In addition, the first rear transfer portion 620 may include: a first rear transfer pulley 623 connected to the first rear frame 621; a second rear transfer belt 625 linked with the first rear transfer pulley 623; and a second front transfer driving unit 627 for driving the first rear transfer pulley 623 and the second rear transfer belt 625.
The first switch 630 switches the article 101 carried into the first switch 630 with the upper surface facing upward so that the first side surface of the article 101 faces upward. When the article 101 is carried into the first switch 630, the pair of first switch belts 631 are driven by the first switch pulleys 633, and the article 101 can be switched between predetermined angles while holding the upper and lower surfaces of the article 101. For example, the predetermined angle may be 90 degrees or 180 degrees. The first switch 630 may include a first rotary drive 635, and the first rotary drive 635 may rotate the first switch belt 631 and the first switch pulley 633 as a whole to switch the articles 101 held between the pair of first switch belts 631. The pair of first transfer belts 631 are driven by the first transfer pulley 633, and can move in the horizontal direction within the first transfer portion 630 while the article 101 rotated by the first transfer portion 630 is held between the pair of first transfer belts 631. For example, when the article 101 is carried into the first switch 630 with the upper surface of the article directed upward, the article 101 switched by 90 degrees by the first switch 630 can be carried out from the first switch 630 to the first rear transfer unit 620 with the lower surface directed upward.
The first inspection line 603 may include a first inspection portion 650, and the first inspection portion 650 may inspect the article 101 located at the first forward transfer portion 610 or the first transfer portion 630. The first inspection section 650 may include a first camera 651 capable of acquiring an image of the article 101, a first inspection section frame 652, and a first elevating section 653. For example, the first photographing device may be a camera.
The first photographing device 651 may be fixed to the first inspection section frame 652. The first inspection section frame 652 moves along the first inspection section rail 655, and thus, the first photographing device 651 can reciprocate in the transfer direction of the article 101 on the first front transfer section 610 or the first switch section 630. The first inspection section frame 652 includes a driving device to move the first inspection section frame 652 along the first inspection section rail 655, and thus, the first photographing device 651 may be moved to a predetermined position on the first inspection section rail 655. The driving device of the first inspection section frame 652 may include any one of driving mechanisms of various driving methods including a hydraulic or electric driver. When the first imaging device 651 is located at a predetermined position, the first imaging device 651 may acquire an image of the upper surface or the first side surface of the article 101 on the first front transfer unit 610 or the first converting unit 630 located therebelow. The first inspection unit 650 can determine whether or not the article 101 is defective by comparing the image of the article 101 acquired by the first imaging device 651 with a reference image stored in advance.
The first inspection section 650 may include a first elevating section 653, and the first elevating section 653 may adjust the height of the first photographing device 651 with respect to the first front transfer section 610 or the first conversion section 630. The first photographing device 651 may be fixed to one end of the first elevating part 653, and the height is adjusted by means of the first elevating part 653. For example, the first elevating portion 653 may include any one of various driving mechanisms including a hydraulic or electric driver. The first elevating unit 653 adjusts the height of the first photographing device 651, so that the distance between the article 101 positioned on the first front transfer unit 610 or the first converting unit 630 and the first photographing device 651 can be adjusted in a predetermined manner. The distance between the first photographing device 651 and the article 101 when the first photographing device 651 inspects the upper surface of the article 101 positioned on the first front transfer unit 610 may be different from the distance between the first photographing device 651 and the article 101 when the first photographing device 651 inspects the first side surface of the article 101 positioned on the first converting unit 630. At this time, the first elevating unit 653 may adjust the height of the first photographing device 651 so that the distance between the first photographing device 651 and the surface of the article 101 is maintained to be predetermined while the article 101 is moved on the first front transfer unit 610 and the first conversion unit 630. By thus adjusting the height of the first photographing device 651, the first photographing device 651 can take an image of the item 101 which is optically focused. Therefore, whether or not the article 101 is defective can be accurately checked.
The transfer device 670 may be disposed adjacent to the first rear transfer unit 620. The transfer device 670 can move (or transfer) the article 101 carried out of the first inspection line 603 to the second inspection line 605. When the article 101 is carried out from the first rear transfer unit 620 in order to move the article 101 from the first inspection line 603 to the second inspection line 605, the transfer device 670 may lift and rotate the article 101. The transfer device 670 may include: a clamp portion 671 including a pair of clamp fingers 671a and a clamp drive portion 671b capable of clamping (clamping) and holding the article 101; and a vacuum suction portion 673 for vacuum-sucking the article 101. The clamp driving portion 671b may move the pair of clamp fingers 671a in a direction toward each other or in a direction away from each other. The clamp driving portion 671b may include any of various driving mechanisms including a hydraulic or electric driver. When the upper surface of the article 101 carried out of the first rear transfer unit 620 faces upward, the pair of gripper fingers 671a can hold (or grip) the second side surface of the article 101. Thus, the article 101 may be held between the pair of gripper fingers 671 a. The vacuum suction portion 673 is brought into contact with the upper surface of the article 101 to form a vacuum state, so that the article 101 can be held by the vacuum suction portion 673. Here, the vacuum state may be understood as a pressure relatively lower than the atmospheric pressure around the vacuum adsorption portion 673.
The transfer device 670 may further include an article rotating unit 675 capable of rotating the article 101, an article lifting unit 677 capable of lifting and lowering the article 101, and a horizontal transfer unit 679 capable of transferring the article 101 in the horizontal direction. The article rotating portion 675 is connectable to the clamping portion 671 and the vacuum suction portion 673. The article rotating unit 675 can rotate the article 101 held by the clamp fingers 671a and the vacuum suction unit 673 by a predetermined angle. For example, the predetermined angle may be 90 degrees. The article rotating portion 675 may include any of various types of driving mechanisms including a hydraulic or electric driver. The article lifting/lowering unit 677 can lift and lower the article rotating unit 675 connected to one end. The article lifting/lowering portion 677 may include any of various driving mechanisms including a hydraulic or electric driver. The other end of the article lifting portion 677 may be connected to the horizontal transfer portion 679. Since the horizontal transfer portion 679 moves along the transfer rail 678, the article rotating portion 675, the article elevating portion 677, the clamping portion 671, and the vacuum adsorbing portion 673 directly or indirectly connected to the horizontal transfer portion 679 can be transferred in the horizontal direction together. With the movement of the horizontal transfer portion 679, the article 101 held by the clamp portion 671 and the vacuum suction portion 673 can be transferred from the first inspection line 603 to the second inspection line 605.
Fig. 21 to 28 are explanatory views showing a method of inspecting an article using an article inspection device of a sixth embodiment of the present disclosure. A method of inspecting an article using an article inspection device according to a sixth embodiment of the present disclosure will be described in detail below with reference to fig. 21 to 28.
In the method of inspecting an article by the article inspection apparatus 600 according to the sixth embodiment of the present disclosure, the article 101 can be carried into the first inspection line 603 and then carried out of the second inspection line 605. For example, the article 101 may have a rectangular parallelepiped shape having 6 faces. The article 101 may have 6 sides including a pair of first sides having a relatively wide width, a pair of second sides adjacent to the pair of first sides and having a narrower width than the pair of first sides, and upper and lower sides adjacent to the first and second sides. The width of each inspection line may be designed in consideration of the size including the width, area, and height of the article 101 to be transferred. In this embodiment, the width of the first inspection line 603 is wider than the width of the second inspection line 605.
As shown in fig. 21, the article 101 can be introduced into the first inspection line 603 and positioned at the first inspection position 161 of the first forward transfer unit 610. The first imaging device 651 of the first inspection unit 650 is held by the first inspection unit frame 652 and is configured to reciprocate along the first inspection unit rail 655 in the transfer direction of the article 101.

The upper surface of the article 101 can be inspected by the acquired upper surface image. The first lift 653 may adjust the height of the first photographing device 651 so that the distance between the first photographing device 651 and the upper surface of the object 101 becomes a predetermined distance. The first photographing device 651 may be connected to one end of the first shaft 654, and a first elevating part 653 may be connected to the other end of the first shaft 654. Therefore, the first imaging device 651 can be interlocked with the first elevating unit 653.
As shown in fig. 22, after the upper surface of the article 101 is inspected, the article 101 is transferred to the first transfer unit 630, and the first side surface of the article 101 can be inspected while being transferred by the first transfer unit 630. The article 101 can be switched to a predetermined angle in a state of being held between the first switching belt 631 and the first switching pulley 633. As shown in fig. 22, in the case where the article 101 is rotated by 90 degrees, the article 101 may be disposed such that one first side surface of the article 101 faces upward. The first photographing device 651 may move along the first inspection section track 655 so as to be positioned above the item 101. The first camera 651 can acquire an image of the first side of the article 101 facing upward. A first side of the article 101 may be inspected by taking an image of the first side. When the first side of the article 101 faces upward, the first lift 653 may adjust the height of the first photographing device 651 such that the distance between the first photographing device 651 and the first side of the article 101 becomes a predetermined distance. After inspection of one first side of the article 101, the other first side of the article 101 may be inspected. The article 101 is converted by a predetermined angle by means of the first converting part 630 so that the other first side of the article 101 may be directed upward. For example, the predetermined angle may be 180 degrees. By means of the first camera 651, an image of the other, upwardly directed, first side is acquired, so that the other, first side of the object 101 can be inspected. After the inspection of all the pair of first side surfaces of the article 101, the article 101 may be carried out from the first transfer unit 630 with its lower surface facing upward, and transferred to the first rear transfer unit 620 of the first inspection line 603.
As shown in fig. 23, the article 101 may be held by the transfer device 670 at a predetermined position on the first rear transfer portion 620 of the first inspection line 603.
