[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides a three-station fan-shaped sheet feeding device for stacking jigs, including a base 1. The upper surface of the base 1 is sequentially arranged with a feeding station 2, a detection station 3, and a positioning and conveying station 4 along the feeding direction, as well as a PLC controller mounted on the base 1. The feeding station 2 includes a positioning base frame 5 mounted on the upper surface of the base 1. A feeding trolley 6 is mounted on the positioning base frame 5, and a magnetic separator 7 for magnetically separating stacked fan-shaped sheets is fixedly installed on the bearing surface of the feeding trolley 6. The detection station 3 includes a feeding frame 22 mounted on the base 1. The top of the material rack 22 is provided with a double-piece detection component 8 and a vision detection component 9; the positioning and conveying station 4 includes a middle frame 10 fixedly connected to the upper surface of the base 1, a transfer platform 11 slidably connected to the upper surface of the middle frame 10, a positioning table 12 fixedly installed on the upper surface of the transfer platform 11, and a conveying drive component 13 for driving the transfer platform 11 and the positioning table 12 to move on the middle frame 10; the top of the base 1 is provided with a gripping component 14 located above the loading station 2 and the detection station 3, and a negative pressure suction cup 15 is provided at the execution end of the gripping component 14.

[0024] At least two parallel conveying tracks 16 are fixedly connected to the upper surface of the intermediate platform 10. The bottom of the transfer platform 11 is provided with a conveying slider 17 that matches the conveying track 16. The conveying slider 17 moves in a straight line along the conveying track 16 to ensure that the transfer platform 11 will not deviate during the movement, thereby improving the conveying stability.

[0025] The gripping assembly 14 includes a positioning platform 18 fixedly connected to the base 1. A horizontal electric guide rail 19 is installed at the rear end of the positioning platform 18. A vertical electric guide rail 20 is provided on the slider of the horizontal electric guide rail 19. A gripping arm 21 is provided on the slider of the vertical electric guide rail 20. A negative pressure suction cup 15 is fixedly installed at the bottom end of the gripping arm 21. Both the horizontal electric guide rail 19 and the vertical electric guide rail 20 are electrically connected to a PLC controller. The horizontal electric guide rail 19 controls the horizontal movement of the gripping arm 21, and the vertical electric guide rail 20 controls the vertical movement of the gripping arm 21, so that the negative pressure suction cup 15 can accurately reach the designated position to grip or release the fan-shaped sheet, realizing accurate control of the gripping action. The negative pressure suction cup 15 ensures that the gripping is firm and does not damage the sheet.

[0026] The dual-piece detection assembly 8 includes at least one dual-piece detection cylinder 23 installed on the inner wall of the feeding frame 22. At least one infrared sensor 24 is embedded in the piston rod of the dual-piece detection cylinder 23. Both the dual-piece detection cylinder 23 and the infrared sensor 24 are electrically connected to the PLC controller. The dual-piece detection cylinder 23 pushes the infrared sensor 24 close to the sheet material. The infrared sensor 24 emits and receives infrared rays. By detecting the thickness of the sheet material or the reflected signal, it can determine whether multiple sheets are stuck together, effectively preventing two sheets from being fed at the same time and improving production quality.

[0027] The visual inspection component 9 includes multiple CCD inspection cameras 25 embedded in the upper surface of the feeding frame 22. At least one CCD visual light source 26 is installed on the front and rear inner walls of the feeding frame 22. The CCD visual light source 26 is located above and to the side of the CCD inspection camera 25. Both the CCD visual light source 26 and the CCD inspection camera 25 are electrically connected to the PLC controller. The CCD visual light source 26 provides uniform illumination, and the CCD inspection camera 25 captures images of the sheet material. The appearance and size of the sheet material are analyzed through image processing algorithms to detect whether there are defects. The sheet material is visually inspected to identify surface defects or positional deviations, thereby ensuring the quality of the sheet material.

[0028] At least two positioning pins 27 are provided on the upper surfaces of both ends of the positioning platform 12. At least two positioning cylinders 28 are fixedly installed in the middle of the upper surface of the positioning platform 12. The piston rod end of the positioning cylinder 28 is fixedly connected to the positioning clamping plate 29. The positioning pins 27 are used to initially position the sheet material. The positioning cylinder 28 drives the positioning clamping plate 29 to clamp the sheet material, ensuring that the sheet material remains fixed during the transfer process. This realizes the positioning and clamping of the sheet material and prevents it from moving during the conveying process.

[0029] The conveying drive assembly 13 includes a support 30 located at the top of the intermediate platform 10. A ball screw 31 is connected between two supports 30 via bearings. A second servo motor 32 is mounted on one of the supports 30 to drive the ball screw 31 to rotate. A nut connecting block 33, which is fixedly connected to the lower surface of the transfer platform 11, is engaged with the ball screw 31. The second servo motor 32 is electrically connected to the PLC controller. The second servo motor 32 drives the ball screw 31 to rotate, and the nut connecting block 33 converts the rotational motion into linear motion, thereby driving the transfer platform 11 to move along the conveying track 16.

[0030] During operation, the fan-shaped sheets are first magnetically separated at the feeding station 2 by the magnetic separator 7 to prevent sticking. Then, they are picked up by the gripping component 14 and sent to the inspection station 3 for double-sheet inspection and visual inspection to ensure that there is no sticking or defects. The qualified sheets are sent to the positioning and conveying station 4, where they are positioned and clamped by the positioning table 12, and then transferred to the next process by the conveying drive component 13. The whole process is highly automated, which improves production efficiency and product quality.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
