Abstract
Description
Technical Field
[0001] This invention relates to the field of tray loading equipment, specifically to an automatic tray loading equipment for plastic products. Background Technology
[0002] In current production processes for round plastic products (such as round plastic protective covers used on PCB circuit boards to protect electronic components during PCB manufacturing), vibratory feeders are widely used for sorting and arranging these products. Through the vibration of the vibratory feeder, round plastic products can be arranged in an orderly manner and come into contact with each other, forming a continuous output flow. However, a challenge arises when loading these products onto trays: the grooves within the trays used to hold the plastic products are arranged in a rectangular array, with a certain gap between adjacent grooves.
[0003] Traditional automated tray loading equipment typically uses a combination of robotic arms and suction cups for tray loading. However, this method has a significant limitation: it can only load one row of plastic products onto the tray at a time. To fill the entire tray, the robotic arm needs to move back and forth frequently, which not only increases the tray loading time but also reduces overall production efficiency.
[0004] Therefore, we propose an automatic tray loading device for plastic products to solve the above problems. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the present invention provides an automatic tray loading device for plastic products.
[0006] This invention provides an automatic tray loading device for plastic products, comprising a vibratory feeder for neatly outputting plastic products. A conveying guide rail is fixed to the output end of the vibratory feeder. A blocking portion is provided at the end of the conveying guide rail. A worktable is provided at one end of the conveying guide rail, and a groove for placing positioning trays is provided on the worktable. A conveying device for conveying plastic products from the conveying guide rail to the worktable is provided between the conveying guide rail and the worktable. The conveying device includes a plastic product suction device, which includes a mounting plate and an adjustment device mounted on the mounting plate for adjusting several plastic products distributed in a strip within the conveying guide rail to a rectangular array distribution.
[0007] Preferably, the conveying device further includes a mounting frame, on which a linear motor is fixed, and a Z-axis cylinder is fixed to the output end of the linear motor. The output end of the Z-axis cylinder is fixedly connected to the top center of the mounting plate.
[0008] Preferably, the adjustment device includes a fixed guide rail fixed to the bottom of the mounting plate, a Y-axis cylinder fixed to one side of the fixed rail, a drive guide rail fixedly connected to the output end of the Y-axis cylinder, and four equally spaced adjustment components between the fixed guide rail and the drive guide rail. Each equally spaced adjustment component includes a first fixed seat, a second fixed seat, and mounting seats equally spaced between the first fixed seat and the second fixed seat. The first fixed seat and its adjacent mounting seats, the adjacent mounting seats and the second fixed seat and its adjacent mounting seats are all connected by a first telescopic rod. A first spring is sleeved on the outside of the first telescopic rod. A first rotating seat is rotatably connected to the first fixed seat via a first rotating shaft, and a second rotating seat is rotatably connected to the second fixed seat via a second rotating shaft. Two equally spaced adjustment components located in the middle of the adjustment device are connected by a second telescopic rod installed on the two first rotating seats. A second spring is sleeved on the outside of the second telescopic rod. An equally spaced adjustment component located at the end of the adjustment device and its adjacent equally spaced adjustment component are connected by a third telescopic rod installed between the two second rotating seats. A third spring is sleeved on the outside of the third telescopic rod.
[0009] A connecting plate is fixed to the side wall of the second rotating seat. A square slider is fixed to one end of the connecting plate and is slidably connected in the drive guide rail. The first rotating shaft located at one end of the adjustment device is rotatably connected to the fixed guide rail, and the other first rotating shafts are set in the fixed guide rail.
[0010] Elastic components are provided between the first fixed seat and the first rotating seat, and between the second fixed seat and the second rotating seat;
[0011] The mounting base, the first rotating base, and the suction cups at the bottom of the second rotating base.
[0012] Preferably, the end of the conveying guide rail away from the vibratory feeder is provided with a support seat.
[0013] Preferably, the elastic component includes a drive plate fixed to the bottom of the first fixed seat and the second fixed seat. The top of the first rotating seat and the second rotating seat are both provided with arc-shaped grooves, and the drive plate is disposed in the arc-shaped grooves. An arc-shaped spring is installed in the arc-shaped grooves. One end of the arc-shaped spring is fixedly connected to the drive plate, and the other end of the arc-shaped spring is fixedly connected to one end of the arc-shaped groove.
[0014] Preferably, the arc-shaped spring has an arc radius of 3 / 4π when not subjected to external force.
[0015] Preferably, when the equal-spaced adjustment components are on the same straight line, the arc of the circular spring is π.

[0018] Preferably, the first spring, the second spring, and the third spring are all under compression. When the suction cups are arranged in a rectangular array, the first telescopic rod, the second telescopic rod, and the third telescopic rod are all at their maximum extension.
[0019] Compared with related technologies, the present invention provides the following beneficial effects:
[0020] The plastic product suction device in the conveying system is ingeniously designed, allowing for flexible adjustment of the suction cup position and spacing. This enables a conversion from a strip-shaped distribution to a rectangular array distribution (the suction cups will rotate relative to each other at a certain angle before and after deformation; since the plastic product is round, the relative rotation of the suction cups and the plastic product will not affect the product placement into the tray). This ensures that the plastic product can be accurately placed in the tray, reducing manual intervention and errors. Through the coordinated work of core components such as the vibratory feeder, conveyor rails, blocking parts, worktable, and conveying device, the equipment achieves a fully automated conveying process of plastic products from the vibratory feeder to the tray, greatly improving production efficiency.

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0029] Please refer to the following: Figures 1 to 6 This is a highly efficient and precise automatic tray loading device for plastic products, especially suitable for round plastic products that can be easily picked up and placed using suction cups. The device mainly consists of core components such as a vibratory feeder, conveyor rails, blocking components, a worktable, and a conveying device, realizing a fully automated conveying process for plastic products from the vibratory feeder to the tray.
[0030] Vibratory feeder 1 serves as the starting point of the entire system, responsible for neatly and orderly outputting plastic products onto conveyor rail 2. One end of conveyor rail 2 is tightly connected to the output end of vibratory feeder 1, while the other end extends to the vicinity of worktable 4. A blocking part 3 is also provided in between to effectively prevent products from slipping during the conveying process.
[0031] On the workbench 4, a groove 5 is carefully designed to place the positioning tray, ensuring that the tray can be positioned stably and accurately. The conveying device 6 is cleverly installed between the conveying guide rail 2 and the workbench 4, and it is responsible for accurately conveying the plastic products from the conveying guide rail 2 to the tray on the workbench 4.
[0032] The core of the conveying device 6 is the plastic product suction device 7, which consists of two main parts: a mounting plate 71 and an adjusting device 72. The mounting plate 71 serves as the base of the entire suction device, stably supporting the adjusting device 72. The adjusting device 72, with its ingenious design, realizes the transformation of the plastic products from a strip distribution to a rectangular array distribution, laying a solid foundation for subsequent precise placement.
[0033] Specifically, the adjustment device 72 includes a fixed guide rail 721, a Y-axis cylinder 722, a drive guide rail 723, and four equally spaced adjustment components 724 (or it can be designed as several bars, adjusted according to actual needs). The fixed guide rail 721 is securely fixed to the bottom of the mounting plate 71, while the Y-axis cylinder 722, through its powerful driving force, pushes the drive guide rail 723 to move precisely on one side of the fixed guide rail 721.
[0034] The equal-gap adjustment components 724 are key components in the adjustment device 72, cleverly positioned between the fixed guide rail 721 and the drive guide rail 723. Each equal-gap adjustment component 724 consists of a first fixed seat 7241, a second fixed seat 7242, and a mounting seat 7243 equidistantly positioned between them. 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] Furthermore, 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, respectively. This design allows the equidistant adjustment assembly 724 to be flexibly deformed and adjusted under the drive of the Y-axis cylinder 722.
[0036] To further enhance the flexibility and precision of the adjustment, two equally spaced adjustment components 724 located in the middle of the adjustment device 72 are connected by a second telescopic rod 725 installed on the two first rotating seats 7247. A second spring 726 is sleeved on the outer side of the second telescopic rod 725. The equally spaced adjustment component 724 located at the end of the adjustment device 72 is connected to its adjacent equally spaced adjustment component 724 by a third telescopic rod 728 installed between the two second rotating seats 7249. A third spring 729 is sleeved on the outer side of the third telescopic rod 728. The synergistic effect of these telescopic rods and springs allows the suction cup 7251 to flexibly change its 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, with the distance between adjacent suction cups greater than the diameter of the plastic product, thus easily placing the plastic product into the tray. At this time, the four equally spaced adjustment components 724 are parallel to each other, and the second telescopic rod 725 and the third telescopic rod 728 are both perpendicular to the equally spaced adjustment components 724, forming a stable structure.
[0038] When the suction cups 7251 need to be adjusted to a straight line, the piston rod of the Y-axis cylinder 722 retracts, driving the drive guide rail 723 to move towards the fixed guide rail 721. During 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 increases, as does the angle between the second telescopic rod 725 and the first telescopic rod 7244. This causes the first spring 7245, the second spring 726, and the third spring 729 to retract, while the first telescopic rod 7244, the second telescopic rod 725, and the third telescopic rod 728 shorten.
[0039] When all the suction cups 7251 are aligned on a straight line, they are equidistant, with the distance between adjacent suction cups exactly equal to the diameter of the plastic product. This allows for precise suction of tightly packed plastic products on the conveyor rail 2. At this point, the Y-axis cylinder 722 stops working, all the telescopic rods and springs are in their shortest or most compressed state, while the arc-shaped spring 72503 is in a tensile state.
[0040] It is worth mentioning that when the equal spacing adjustment components 724 are on the same straight line, the arc of the arc spring 72503 will be π-shaped, and the drive plate 72501 will be in close contact with one end of the arc groove 72502. When the suction cups 7251 are arranged in a rectangular array, the arc of the 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 stably supports the entire conveying device 6, while the linear motor 62, through its powerful driving force, propels the Z-axis cylinder 63 and the mounting plate 71 to move precisely 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 precise picking up and placing of plastic products.
[0042] In addition, a support seat 8 is provided at the end of the conveying guide rail 2 away from the vibratory plate 1, providing additional support and stability for the conveying guide rail 2. The ingenious design of the elastic component 7250 further enhances the flexibility and stability of the adjustment device 72. It includes a drive plate 72501 fixed to the bottom of the first fixed seat 7241 and the second fixed seat 7242, and an arc-shaped groove 72502 located at the top of the first rotating seat 7247 and the second rotating seat 7249. An arc-shaped spring 72503 is also installed within the arc-shaped groove 72502, which is tightly connected to one end of the drive plate 72501 and the arc-shaped groove 72502, together forming the core part of the elastic component 7250.
[0043] In summary, this automatic tray loading equipment for plastic products, with its ingenious design and high efficiency, achieves a fully automated and precise conveying process for plastic products from the vibratory feeder to the tray. It not only improves production efficiency but also significantly reduces manual intervention and errors, bringing great convenience and benefits to the production and processing of plastic products.
