DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figures 1 to 6 , an efficient and accurate automatic tray loading equipment for plastic products, especially suitable for plastic products with round shapes, which can be easily sucked and placed by suction cups. The equipment is mainly composed of core components such as vibration plate, conveying guide rail, blocking part, workbench, conveying device, etc., realizing the fully automated conveying process of plastic products from vibration plate to material plate.

[0030] The vibration plate 1 is the starting point of the whole system, responsible for neatly and orderly outputting plastic products to the conveying guide rail 2. One end of the conveying guide rail 2 is closely connected to the output end of the vibration plate 1, and the other end extends to the vicinity of the workbench 4, and a blocking part 3 is also provided in between to effectively prevent the product from slipping during the conveying process.

[0031] On the workbench 4, a groove 5 for placing and positioning the material tray is carefully designed to ensure that the material tray can be positioned stably and accurately. The conveying device 6 is cleverly set up between the conveying guide rail 2 and the workbench 4, and it undertakes the important task of accurately conveying the plastic product from the conveying guide rail 2 to the material tray on the workbench 4.

[0032] The core of the conveying device 6 is the plastic product suction device 7, which consists of two major parts: a mounting plate 71 and an adjustment device 72. The mounting plate 71 serves as the base of the entire suction device and stably carries the adjustment device 72. The adjustment device 72, with its ingenious design, realizes the transformation of the plastic product distribution from strip distribution to rectangular array distribution, laying a solid foundation for subsequent precise placement.

[0033] Specifically, the adjustment device 72 includes a fixed rail 721, a Y-axis cylinder 722, a driving rail 723, and four equally spaced adjustment components 724 (which can also be designed as several bars and adjusted according to actual needs). The fixed rail 721 is firmly fixed to the bottom of the mounting plate 71, and the Y-axis cylinder 722, through its powerful driving force, pushes the driving rail 723 to move precisely on one side of the fixed rail 721.

[0034] The equal spacing adjustment components 724 are key components in the adjustment device 72, and they are cleverly arranged between the fixed guide rail 721 and the driving guide rail 723. Each equal spacing adjustment component 724 is composed of a first fixed seat 7241, a second fixed seat 7242, and a mounting seat 7243 arranged equidistantly therebetween. These seats are connected by a first telescopic rod 7244 and a first spring 7245, forming a structure that is both stable and flexible.

[0035] In addition, the first fixed seat 7241 and the second fixed seat 7242 are rotatably connected to the first rotating seat 7247 and the second rotating seat 7249 via the first rotating shaft 7246 and the second rotating shaft 7248. This design enables the equal spacing adjustment component 724 to be flexibly deformed and adjusted under the drive of the Y-axis cylinder 722.

[0036] In order to further enhance the flexibility and accuracy of adjustment, the two equal-distance adjustment components 724 located in the middle of the adjustment device 72 are connected by a second telescopic rod 725 installed on two first rotating seats 7247, and the second telescopic rod 725 is connected to the outer side with a second spring 726. The equal-distance adjustment components 724 located at the ends of the adjustment device 72 are connected to the adjacent equal-distance adjustment components 724 by a third telescopic rod 728 installed between two second rotating seats 7249, and the outer side of the third telescopic rod 728 is provided with a third spring 729. The coordinated action of these telescopic rods and springs enables the suction cup 7251 to flexibly change the position and spacing as needed.

[0037] When the Y-axis cylinder 722 is at its maximum extension, all the suction cups 7251 are arranged in a rectangular array, and the distance between adjacent suction cups is greater than the diameter of the plastic product, so that the plastic product can be easily placed in the tray. At this time, the four equal-distance adjustment components 724 are parallel to each other, and the second telescopic rod 725 and the third telescopic rod 728 are perpendicular to the equal-distance adjustment components 724, forming a stable structure.

[0038] When the suction cups 7251 need to be adjusted to be distributed in a straight line, the piston rod of the Y-axis cylinder 722 contracts, driving the driving guide rail 723 to move toward the fixed guide rail 721. In this process, due to the special design of the arc-shaped spring 72503, the angle between the third telescopic rod 728 and the first telescopic rod 7244 will increase, and the angle between the second telescopic rod 725 and the first telescopic rod 7244 will also increase. This causes the first spring 7245, the second spring 726 and the third spring 729 to contract, while the first telescopic rod 7244, the second telescopic rod 725 and the third telescopic rod 728 will shorten.

[0039] When all the suction cups 7251 are on the same straight line, they are evenly spaced, and the distance between adjacent suction cups is exactly equal to the diameter of the plastic product, so that the plastic products closely arranged on the conveying guide rail 2 can be accurately sucked. At this time, the Y-axis cylinder 722 stops working, all telescopic rods and springs are in the shortest or most compressed state, and the arc spring 72503 is in a tension state.

[0040] It is worth mentioning that when the equal-spacing adjustment components 724 are on the same straight line, the curvature of the circular arc spring 72503 will be π-shaped, and the driving plate 72501 will be in close contact with one end of the circular arc groove 72502. When the suction cups 7251 are distributed in a rectangular array, the curvature of the circular arc spring 72503 will become 1 / 2π.

[0041] The conveying device 6 also includes a mounting frame 61, a linear motor 62 and a Z-axis cylinder 63. The mounting frame 61 firmly supports the entire conveying device 6, and the linear motor 62, through its powerful driving force, drives the Z-axis cylinder 63 and the mounting plate 71 to move accurately in the X-axis direction. The Z-axis cylinder 63 is responsible for driving the mounting plate 71 to move up and down in the Z-axis direction, thereby achieving accurate suction and placement of plastic products.

[0042] In addition, a support seat 8 is provided at one end of the conveying rail 2 away from the vibration plate 1 to provide additional support and stability for the conveying rail 2. The ingenious design of the elastic component 7250 further enhances the flexibility and stability of the adjustment device 72. It includes a driving plate 72501 fixed to the bottom of the first fixed seat 7241 and the second fixed seat 7242, and an arc-shaped groove 72502 provided at the top of the first rotating seat 7247 and the second rotating seat 7249. An arc-shaped spring 72503 is also installed in the arc-shaped groove 72502, which is closely connected with the driving plate 72501 and one end of the arc-shaped groove 72502, and together constitutes the core part of the elastic component 7250.

[0043] In summary, the automatic tray loading equipment for plastic products, with its exquisite design and efficient performance, realizes the fully automated and precise conveying process of plastic products from the vibrating tray to the material tray. It not only improves production efficiency, but also greatly reduces manual intervention and errors, bringing great convenience and benefits to the production and processing of plastic products.
