Preferably, the bottom area of each work piece holding space is capable of sufficiently holding a single work piece therein. -As mentioned above, it is possible to provide _ auxiliary conveying part (for example,-screening package = flat part for accepting work pieces transferred to it, and the work piece is rotated to the designated unloading position by auxiliary input = point, where the The conveying unit is a female melon in the toweler part of Yunyi β 八 rb γ-1 in an outer cover, so the work piece holding space is enclosed between the surrounding wall of the hollow part and the chassis, and the middle part of the sixth part. The chassis is set to be approximately the same height as the upper surface of the auxiliary conveying portion: Here, an opening is formed to partially cut away the surrounding wall Γ of the nail empty portion and is positioned directly above the upper surface of the auxiliary conveying portion. According to the foregoing structure, it is possible to smoothly convey the work pieces that are continuously conveyed to the conveying unit via the slope toward the auxiliary conveying unit. Herein, it is preferable that the chassis of the hollow part of the outer cover and the The upper surface of the auxiliary conveying unit cooperates; alternatively, the chassis of the hollow portion can be arranged slightly higher than the upper surface of the auxiliary conveying unit. Therefore, the work piece can be prevented from being accidentally deviated from the position. And rolling; and can reliably transport the work piece towards the auxiliary conveying unit in an appropriate position. In addition, 'a gap is arranged between the side surface of the conveying unit and the surrounding surface of the hollow portion, in other words, between the work piece m and The opening 'between one part of the conveying unit is used to transfer work pieces to this auxiliary conveying unit, so that when the conveying unit is rotated, two work pieces can be caught between the conveying unit and the cover. Due to the above-mentioned gap, so The conveying unit can rotate smoothly without directly contacting the surrounding surface of the hollow part of the outer cover. Furthermore, a discharge channel that allows the work piece to be discharged is placed downstream of the conveying order 〇 \ 87 \ 87925.DOC4 The gabion is conveyed to the outside of the auxiliary conveying unit when the auxiliary method is conveyed. The conveying unit is rotated, so that no work piece can be safely passed through the discharge channel as described above. When the work piece is rotated to the auxiliary conveying place and the work piece remains in the work piece holding space, it can be safely discharged to the outside through the discharge channel. That is, it is possible to avoid the auxiliary auxiliary transport note s and still exist in the work piece holding space: the condition that the work piece 'occurs a hindrance to another work piece newly introduced from the slope' into the work piece holding space , And to avoid the situation where multiple work pieces enter the holding space of the relative work by mistake. Therefore, it is possible to avoid being unable to be aligned with the work piece due to the inability to identify the alignment status of the work pieces; Inconsistent results of continuous inspection results occur. In addition, the conveying unit and the auxiliary conveying unit cooperate with each other at a relative moving speed at a designated position where they meet together; and the unloading unit can convey the self-assisted rotating unit to the place. The jade work piece is unloaded, that is, the position is substantially fixed at the same relative moving speed at the position for positioning the work piece in the conveying unit and the position for receiving the work piece in the auxiliary conveying unit. Therefore, the work pieces can be smoothly and without difficulty conveyed from the carousel unit to the auxiliary conveying unit (that is, from the conveying table to the screening table). A work piece screening method of the present invention basically includes three steps, that is, 'a first conveying step is used for continuously conveying the work piece to be inspected via a slope' and a second conveying step is used to independently place the self-slopes Continuously conveyed work pieces enter into a plurality of work piece holding spaces. These spaces are connected, '· ί, and the ground is located near the slope and is arranged at a specified pitch therebetween. O: \ 87 \ 87925 .DOC4 -10- 200424514 and each-space combination-bounce suppression wall is used to restrain the work piece from jumping from the space to the outside 'and a discharging step is used to drop each work piece at the designated position, and the inspection result Agree. According to the work piece screening method, each work piece continuously transferred from the slope to the conveying unit can be surely and safely held inside the holding space of each work piece without accidentally jumping to the outside of the conveying unit; therefore, each A work piece can be reliably conveyed by a conveying unit and is screened in a discharge unit. As described above, its feature is that the time during which the conveying unit moves a pitch corresponding to the work piece holding space is set to be shorter than the time interval at which each work piece is transferred from the slope. That is, even when the next work piece is supplied from the slope at an intermediate position between the adjacent work piece holding spaces, the next work piece holding space is soon to be used to safely hold the next work piece at among them. Therefore, it can be reliably avoided that the work piece cannot be held in the work piece holding space, or a plurality of work pieces are erroneously held in the same work piece holding space. 5 | 丨 浐 _ t P This is enough to prevent the work piece from pulsating （, (outside; and to prevent the quasi-sequence of the work piece cannot be discriminated 'because multiple work pieces can reliably prevent the same work piece from being held in the wrong space.

A% -like hollow portion 49 is formed on the upper surface of the outer cover 46, so the conveying table 42 is accommodated in the hollow portion 49 in a rotatable manner. One work. The work holding space 50 is surrounded by a surrounding wall 49a and a bottom 49b of one of the hollow portions 49 (see FIGS. 4 and 6), and each notch 47 of the conveying table 42. Therefore, A plurality of work piece holding spaces defined by the equal notches 47 are tied to the hollow portion 49 and arranged around the conveying table 42. Here, the area of a portion of the bottom portion 49b defined by each notch 47 is set to be sufficiently larger than a specified area in which a work piece 15 is accommodated. A hole 46a communicating with the lower end portion of the discharge chute 33 is formed at one end portion of the cover 46. That is, the slope of the discharge chute 33 communicates with the inside of the hollow portion 49 (that is, the inside of the work piece holding space 50) via the hole 46a. '· Occasionally, the surrounding wall 49a of the hollow portion 49 and the conveying table 42 are respectively set to a designated height or a higher position, so as to surely prevent the receiving area I from causing the fierce self-discharge chute 33 to be discharged. Work piece 15 runs away. A runout suppression wall is constructed in this way to prevent the work piece 15 from jumping unexpectedly.

The sieve k σ 43 is continuously conveyed to the work pieces 15 there by the conveying table 42. Therefore, the work pieces 5 are at a specified distance therebetween and are arranged around The work piece receiving portion 43a is on the upper surface; therefore, it is separately input into the aforementioned boxes. Specifically, when the work piece 15 is distinguished from one according to the inspection result produced by the inspection unit 30, When a good product, for example, Tian Zuo 15 passes the good product storage box, the exhaust device 53a is activated to blow the work piece 15 into the good product storage box. When the work piece 15 is identified as a defective product When, for example, when the work piece 15 passes the O: \ 87 \ 87925.DOC4 -17- 200424514 T trap product storage box, the exhaust device 53b is activated to bring the work piece 15k into the defective product storage Therefore, it is possible to identify these work pieces 15 between the good product and the defective product A, which are finely divided to reach the good product storage box and the defective product storage box. The other exhausts are set 53c and 53d are properly activated to blow the work piece 15 Enter the corresponding product storage box to reflect the degree and type of the defect. The visual inspection device 10 further includes electrical control elements such as a central processing unit (CPU), a read-only memory (ROM), and a random access memory. (RAM), and an image processing element including a ccd camera (for example, 36a) in addition to the aforementioned electromechanical elements. The image processing element performs image processing operations on images obtained by a cCD camera (• J 3 36a), The work pieces 15 between good and defective products are identified. In addition, the image processing element is equipped with a display screen for enlarging and displaying each work = 15 six sides (or a hexagonal structure) ); Therefore, the operator can view the image to visually judge whether the work piece 15 is a good product or a defective product. Then, an example (see FIG. 5) of a work piece 15 to be inspected using the aforementioned visual inspection device 10, such as a capacitor wafer for visual inspection and screening will be described. Prior to the inspection, these work pieces 15 were kept before the work piece supply funnel 24 as early as 7G 20; then, a power switch (not shown) of the appearance inspection device 10 was turned on, thereby activating the aforementioned units and components respectively. To perform the specified action. In the work piece supply unit 20, a specified number of work pieces 15 are supplied from a hopper 24 to a feeder via a supply chute 25. Each work piece 15 supplied to the feeder 23 is transferred to the tip portion of the feeder 23 once it is driven to generate O: \ 87 \ 87925 DOC4 -18- 200424514. Therefore, it is self-feeding. The tip portion of the device 23 is discharged into the space. When the work piece 15 passes through the middle part of the interconnecting member 35 and falls, the CCD camera to% 4 captures images on the individual sides of the work piece 15 and thus does not affect the photographing. Based on the images related to the six sides of the work piece 15, the image processing element is operated to identify whether the work piece 15 is a good product or a defective product. Based on the comparison with the external standard 'specified reference regarding dirt, flaws, and abnormal substances adhered to it,' the identification is performed by photographing the work piece 15. In this case, in the image processing element camp, The " magnified " image captured on the six sides of the work piece 15 is displayed on the screen; therefore, the operator can detect defects on any part of the work piece 15.
