[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] like Figures 1-6 As shown, the first embodiment of this utility model is as follows:

[0041] like Figure 1 The visual inspection device for product feeding and straightening in this embodiment mainly includes a working platform 1 and a baffle 2, a feeding conveyor belt 4, a pushing component 5, a receiving component 6, a visual inspection component 7, and a handling component 8 installed on the working platform 1.

[0042] The positional relationships of the above structural units are shown below:

[0043] The feeding conveyor belt 4 runs in the left-right direction and is installed on the left side of the work platform 1. A pushing component 5 is installed on the right side of the feeding conveyor belt 4. A receiving component 6 is installed behind the pushing component 5. A vision inspection component 7 is installed in front of the pushing component 5. A handling component 8 is installed behind the receiving component 6. A baffle 2 is installed between the feeding conveyor belt 4 and the receiving component 6.

[0044] like Figure 1 Several mounting brackets 3 are installed on the working platform 1 below the baffle 2. The baffle 2 is embedded into the mounting brackets 3 from top to bottom, thereby realizing the quick installation and removal of the baffle 2. In addition, the baffle 2 has through holes for the feeding conveyor belt 4 and the pushing assembly 5 to be adapted, so as to facilitate the feeding of the product 9 on the feeding conveyor belt 4 to the pushing assembly 5.

[0045] like Figure 2 The material pushing assembly 5 mainly includes a first material pushing frame 501, a material pushing cylinder 502, a material pushing linkage plate 503, a material pushing block 504, a second material pushing frame 505, a bottom support cylinder 506, a bottom support block 507, a material dropping channel 509, a material dropping bin 510, a material pushing limit frame 511, and a material pushing limit rod 512.

[0046] A first pusher frame 501 is mounted on the work platform 1, and a second pusher frame 505 is mounted on the rear side of the first pusher frame 501. A pusher cylinder 502 mounted on the first pusher frame 501 drives a pusher block 504 to move in the front-to-back direction via a pusher linkage plate 503. A bottom support cylinder 506 mounted on the second pusher frame 505 drives a bottom support block 507 to move in the left-to-right direction. A notch 508 is provided on the second pusher frame 505 on the right side of the feeding conveyor belt 4. This notch 508 is connected to a discharge bin 510 located on the work platform 1 below via a discharge channel 509. The bottom support cylinder 506 drives the bottom support block 507 to move, thereby opening and closing the notch 508. When product 9 on the feeding conveyor belt 4 is fed to the notch 508 of the pushing component 5, the bottom support block 507 is initially located inside the notch 508, causing the notch 508 to close the connection with the lower drop channel 509. Then, the product 9 is visually inspected by the vision inspection component 7. If the inspection is qualified, the product 9 is pushed to the receiving component 6 on the rear side by the pushing block 504. If the inspection is unqualified, the bottom support block 507 moves to the right and leaves the notch 508, so that the notch 508 is connected with the lower drop channel 509, and the unqualified product 9 falls into the lower drop bin 510.

[0047] During the operation of the pusher block 504, the pusher limiting rod 512, which is installed on the top of the pusher limiting frame 511 at the rear, limits the pusher block 504 in the front and rear directions.

[0048] like Figure 3 The receiving component 6 mainly includes a receiving linear motor module 601, a receiving support frame 602, a receiving platform 603, a receiving fixture 604, a sensing sheet 605, and a sensor 606.

[0049] The receiving linear motor module 601 is installed on the working platform 1. Three contoured receiving fixtures 604 for accommodating products 9 are evenly installed on the receiving platform 603 at the top of the receiving support frame 602 along the left and right directions. The receiving linear motor module 601 drives the receiving support frame 602 to move in the left and right directions, thereby sequentially pushing the products pushed by the pusher block 504 into the three receiving fixtures 604.

[0050] In addition, during the movement of the receiving platform 603, the sensor 605 on one side of the bottom of the receiving support frame 602 is adapted to the sensor 606 installed on the receiving linear motor module 601 to sense the position of the receiving platform 603.

[0051] like Figure 4The visual inspection component 7 mainly includes a camera 703 and a light source 708, with the camera 703 located directly above the light source 708. When the product 9 is conveyed directly below the camera 703, it undergoes visual inspection through the camera 703 to check whether its appearance is up to standard.

[0052] The camera 703 is fixedly mounted on the top of the camera stand 701 via the camera mounting bracket 702, while the light source 708 is mounted vertically on the side of the light source stand 704 near the top via the light source mounting bracket 707. A vertically distributed sliding groove 705 is provided on the side of the light source stand 704 near the top. The light source mounting bracket 707 is slidably mounted in the sliding groove 705 via a slide block 706, and can be locked in place by bolts or other locking devices after adjustment.

[0053] like Figure 5 The handling component 8 mainly includes a handling stand 801, a handling linear motor module 802, a handling adapter 803, and a handling mechanism 804.

[0054] The transport stand 801 is installed on the work platform 1. The transport linear motor module 802 installed on the top of the transport stand 801 drives the transport mechanism 804 below to move in the left and right directions through the transport adapter 803.

[0055] like Figure 6 The handling mechanism 804 mainly includes a handling support frame 805, a handling suction cup 806, a handling positioning column 807, a handling limit frame 808, and a handling limit block 809.

[0056] The transport support frame 805 is installed at the bottom of the transport adapter frame 803. Three transport suction cups 806 are evenly installed at the bottom of the transport support frame 805 along the left and right directions. The three transport suction cups 806 correspond to the three receiving fixtures 604 mentioned above. The product 9 located in the receiving fixture 604 is transported out through the transport suction cups 806.

[0057] During the handling process, the two handling positioning posts 807 on the left and right sides of the handling suction cup 806 are positioned with the two positioning holes on the left and right sides of the product 9, thereby providing positioning accuracy during handling.

[0058] In addition, during handling, in order to prevent the product 9 from being restricted in the vertical direction, the top of the rear side of the product 9 is restricted by the handling limit block 809 installed at the bottom of the handling limit frame 808.

[0059] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
