[0030] An automatic feeding device with automatic detection function, such as Figure 1 and Figure 2As shown, the system includes a machine base 5, which is equipped with a transmission module 1, a vision inspection module 2, a gripping module 3, and a feeding tray 4. The transmission module 1 is used to transport the product 6 from the upstream equipment to the machine base 5; the vision inspection module 2 is used to perform image inspection on the product 6; the gripping module 3 includes a gripper assembly, a moving assembly, and a rotating assembly. The gripper assembly is used to grip the product 6, the moving assembly is used to move the gripper assembly, and the rotating assembly is used to rotate the gripper assembly so that the reverse side of the product 6 is inspected by the vision inspection module 2; the gripping module 3 grips the product 6 into the feeding tray 4, completing the feeding of the product 6.

[0031] The moving component includes a moving bracket 301, which is slidably mounted on the machine base 5 in the horizontal direction. Y-axis guide rails 302 are provided on both sides of the moving bracket 301 inside the machine base 5. The left and right ends of the moving bracket 301 are respectively connected to the Y-axis guide rails 302. The transmission module 1 and the unloading tray 4 are arranged along the Y-axis direction. The moving bracket 301 is driven to move along the Y-axis through the Y-axis guide rails 302, so that the gripping module 3 can move the product 6 from the transmission module 1 to the unloading tray 4.

[0032] like Figure 3 As shown, the moving component also includes a lifting bracket 303, which is slidably mounted on the moving bracket 301 in a vertical direction. A rotating component is mounted on the lifting bracket 303, and a gripper component is mounted on the rotating component. The lifting bracket 303 can drive the rotating component to move up and down, indirectly driving the gripper component to move up and down. The lifting bracket 303 includes a vertically arranged guide rail. A slider is fixed on the moving bracket 301, and the guide rail is slidably connected to the slider. A lifting motor 304 is mounted on the moving bracket 301. A gear disk is connected to the output shaft of the lifting motor 304, and the gear disk meshes with a vertically arranged rack on the guide rail, thereby driving the guide rail to move up and down via the lifting motor 304. In this embodiment, the lifting bracket 303 has three guide rails, with the lifting motor 304 mounted only on the middle guide rail of the moving bracket 301.

[0033] The gripper assembly includes a gripper frame 308, which is rectangular in shape and includes four horizontal bars. These four horizontal bars are fixed together by three vertical bars. Several vacuum nozzles 309 are located at the bottom of the gripper frame 308, arranged along the length of the horizontal bars. This allows the gripper assembly to cover a larger area, enabling it to handle products with dimensions up to 2000*600mm, thus solving the problem of handling large-sized products and improving compatibility.

[0034] The rotating assembly includes a mounting block 305 disposed on the lifting bracket 303. A rotating shaft 306 is disposed on the mounting block 305. The gripper assembly is fixed on the rotating shaft 306 and rotates with the rotating shaft 306. There are three mounting blocks 305. A rotary motor 307 is disposed on one of the mounting blocks 305. The output shaft of the rotary motor 307 is connected to the rotating shaft 306 to drive the rotating shaft 306 to rotate, thereby driving the gripper assembly to rotate.

[0035] like Figure 4 and Figure 5 As shown, the transmission module includes a conveying track set on the machine base 5, and a tooling plate 101 is slidably connected on the conveying track. The tooling plate 101 is used to place the product 6. The conveying track is connected to upstream and downstream equipment. The tooling plate 101 can enter the machine base 5 from the upstream equipment along the conveying track. After the gripping module 3 grips the product 6, the tooling plate 101 is moved out of the conveying track so that the next tooling plate 101 carrying the product 6 can enter the machine base 5.

[0036] The conveyor track includes two parallel conveyor belts 102. The tooling plate 101 is attached to the top of the conveyor belts 102 and moves with them. A lifting cylinder 103 is installed below the machine base 5 between the two conveyor belts 102. The lifting cylinder 103 is used to lift the tooling plate 101 and separate it from the conveyor belts 102. Multiple lifting cylinders 103 are arranged along the conveying direction of the conveyor belts 102 to ensure stability when lifting the tooling plate 101. When the tooling plate 101 moves to the predetermined position, the conveyor belts 102 stop working, and the output shaft of the lifting cylinder 103 rises to lift the tooling plate 101, preventing it from slipping on the conveyor belts 102 and causing inaccurate positioning of the product 6. After the gripping module 3 grips the product 6, the output shaft of the lifting cylinder 103 retracts, the tooling plate 101 re-fits with the conveyor belt 102, and the conveyor belt 102 starts to move the tooling plate 101 out of the machine base 5.

[0037] like Figure 2 and Figure 6 As shown, the visual inspection module 2 includes a mounting rod 201 rotatably connected to the machine base 5. The mounting rod 201 is located inside the top wall of the machine base 5, and the unloading tray 4 is located below the mounting rod 201. An inspection camera 202 is mounted on the mounting rod 201, and a through hole is provided in the top wall of the machine base 5, through which the inspection camera 202 takes pictures. Multiple inspection cameras 202 are mounted on the mounting rod 201 and take pictures along the length of the gripper frame 308, increasing the shooting range of the visual inspection module 2 and making it suitable for larger products 6. A drive motor 203 is provided on the machine base 5 to drive the mounting rod 201 to rotate. The mounting rod 201 is connected to the output shaft of the drive motor 203, allowing the inspection camera 202 to rotate and adjust its shooting angle.

[0038] When the gripping module 3 rotates the product 6, the drive motor 203 drives the detection camera 202 to rotate to face the back of the product 6 so as to take pictures and detect the back of the product 6; when the gripping module 3 grips the product 6 into the unloading tray 4, the drive motor 203 drives the detection camera 202 to rotate vertically downward so as to take pictures and detect the front of the product 6.

[0039] In this embodiment, the gripping module 3 rotates the product 6 by 145°. The reverse side of the product 6 is rotated 145° from vertically downward towards the detection camera 202, and the lens of the detection camera 202 is rotated 35° from vertically downward towards the product 6, so that the lens of the detection camera 202 faces the reverse side of the product 6.

[0040] The overall working process of this utility model is as follows:

[0041] The tooling plate 101, carrying product 6, enters the machine 5 from the upstream equipment along the conveyor belt 102. After moving to below the gripper assembly, it stops. The lifting cylinder 103 lifts the tooling plate 101, and the lifting bracket 303 moves downward to allow the gripper assembly to pick up product 6 and then moves upward. The rotating component drives the gripper assembly to rotate, causing product 6 to rotate 145° towards the inspection camera 202. The drive motor 203 then drives the inspection camera 202 to rotate towards product 6, allowing the inspection camera 202 to take pictures of the reverse side of product 6. After the inspection is completed, the rotating component rotates product 6 back to its original position. Then, the moving bracket 301 moves outward to place product 6 in the unloading tray 4. The drive motor 203 drives the inspection camera 202 to rotate back to a vertically downward position, allowing the inspection camera 202 to take pictures of the front side of product 6. After the inspection is completed, the operator can remove product 6 from the unloading tray 4, thus completing the unloading of product 6 and realizing the feature inspection of both the front and back sides of product 6.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
