Description
Technical Field

[0002] In machining, automated assembly, and other fields, it is often necessary to systematically feed and precisely transfer rod-shaped and shaft-like workpieces. Currently, common feeding methods for rods include vibratory feeders, conveyor belts, or manual placement. Vibratory feeders can easily cause surface damage to long rods or workpieces with high surface finish requirements; conveyor belt structures are difficult to separate and precisely position rods individually, often requiring complex separation mechanisms, resulting in high equipment costs and large footprints; while manual placement is inefficient, labor-intensive, and difficult to guarantee positional accuracy, becoming a bottleneck restricting the efficiency of automated production lines. Therefore, there is an urgent need for a compact feeding device that can reliably separate and precisely position rods individually, and achieve automated transfer to meet the demands of modern high-efficiency, high-quality production.

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0012] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component 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.
[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0014] To solve the above technical problems, such as Figure 1-2 As shown, this utility model designs a guide rail feeding device, including a base plate 1. A support platform 2 and a support column 3 are arranged on the base plate 1. The base plate 1 serves as the installation reference for the entire device, ensuring the relative positional accuracy between the components. A horizontal reciprocating linear guide rail feeding module 4 is provided on the support platform 2. This module is a mechanical unit that integrates a linear guide rail and a drive mechanism (such as a ball screw, synchronous belt, or linear motor) into one unit. It is specifically designed to achieve high-precision reciprocating linear motion in the horizontal direction. It is widely used in fields such as automation equipment, CNC machine tools, laser cutting, 3C assembly, and semiconductor equipment. It provides power through ball screws and other means, and provides high-precision, low-friction linear guidance through linear guide rails, bearing the slider and load.
[0015] The feeding module is equipped with a reciprocating slide 5, and a support plate 6 is provided on the slide 5. The support plate 6 is provided with several limiting grooves evenly spaced along the front and back. Each limiting groove is used to place a rod workpiece. The slide 5 and the support plate 6 perform smooth and precise intermittent linear motion. The limiting grooves are preferably V-shaped grooves, which can accurately position and reliably support the rod workpieces and prevent the workpieces from rolling during the conveying process. The design of multiple limiting grooves enables the device to continuously receive and convey multiple workpieces.
[0016] The top of the support column 3 is provided with two symmetrical guide plates 7. The upper surface of the guide plates 7 is inclined downward, so that the rod workpiece placed on it can roll down along the guide plates 7. The symmetrical guide plates 7 form a material storage track. The weight of the rod workpiece itself is used as a power source to make it roll down automatically to the working position, eliminating the need for an additional power device and achieving the purpose of simplifying the structure and reducing energy consumption. A baffle 8 is provided at the end of the guide plate 7. A gap channel is left between the baffle 8 and the guide plate 7. The size of the gap channel only allows a single rod workpiece to pass through. The narrow gap channel formed by the baffle 8 and the guide plate 7 physically restricts only one workpiece to be in the ready-to-feed state, ensuring the reliability of feeding.
[0017] A linear cylinder 10 is provided on the side of the support column 3 near the support platform 2. The piston rod of the linear cylinder 10 is connected to a push block 11, and a push plate 12 is provided on the top of the push block 11. A support frame 13 is provided on the left and right sides of the support platform 2, and the tops of the two support frames 13 are connected by a fixing plate 14. The baffle 8 and the fixing plate 14 are located on the upper and lower sides of the push plate 12, respectively. A first material discharge groove 15 is provided on the push plate 12, and a second material discharge groove 16 is provided on the fixing plate 14. When the push plate 12 is pushed by the linear cylinder 10, the first material discharge groove 15 can interact with the second material discharge groove 16. Aligning the material troughs 16 allows the workpiece to fall from the second material drop trough 16 into the limiting groove on the support plate 6. The linear cylinder 10 provides stable and reliable linear drive power. The push plate 12 is the key actuator. The first material drop trough 15 on it and the second material drop trough 16 on the fixed plate 14 together form a controlled gate system. When the push plate 12 is pushed by the cylinder, its first material drop trough 15 moves to coincide with the second material drop trough 16 on the fixed plate 14, forming a channel that allows the workpiece to fall. When the push plate 12 is reset, its physical part will close this channel. This design achieves precise timing control of the workpiece falling.
[0018] In this embodiment, it is further preferred that the tilt angle of the guide plate 7 is set so that the rod workpiece can automatically roll downward to the gap channel between the baffle 8 and the guide plate 7 under the action of gravity. The effect is that the rod workpiece can rely entirely on its own weight to overcome the friction with the surface of the guide plate 7 and achieve continuous and stable automatic rolling. This not only eliminates the need for an additional pushing power device, but also simplifies the structure and reduces costs.
[0019] In this embodiment, it is further preferred that a cover 9 is provided on the outer side of the guide plate 7, the cover 9 covers the guide plate 7 on the inner side, and there is a space between the cover 9 and the upper surface of the guide plate 7 for the rod to slide down. The end of the cover 9 is connected to the baffle 8. The cover 9 can effectively prevent the rod workpiece from accidentally falling off the side of the guide plate 7 during the rolling process.
[0020] In this embodiment, it is further preferred that the linear cylinder 10 is a double-rod cylinder. Due to its symmetrical piston rod structure on both sides, the double-rod cylinder has better resistance to off-center loads and better operational stability than the single-rod cylinder.
[0021] In this embodiment, it is further preferred that the first discharge groove 15 has flared structures 17 at both ends along its length direction. The diameter of the flared structure 17 is larger than the diameter of the middle part of the first discharge groove 15. The flared structure 17 is used to facilitate the introduction of the rod workpiece. When the end of the rod workpiece is about to enter or leave the discharge groove, the flared structure 17 forms a natural guide slope. This slope can guide the end of the workpiece to slide smoothly into or out of the discharge groove.
[0022] In practice, the operator places multiple rod-shaped workpieces on symmetrically arranged guide plates 7. Under gravity, the workpieces automatically roll downwards along the inclined surface until the foremost workpiece is blocked by a baffle 8 and falls into the gap channel between the baffle 8 and guide plate 7, which can only accommodate a single workpiece. The foremost rod-shaped workpiece stops precisely in the first drop groove 15 of the push plate 12. Simultaneously, the linear guide rail feeding module drives the pallet 6 to move, causing an empty limiting groove to stop precisely below the second drop groove 16 of the fixed plate 14. At the start of the feeding process, the linear guide rail... When the linear cylinder 10 is activated, it drives the push block 11 and the push plate 12 to move forward. When the push plate 12 moves forward, its main body first closes the outlet of the gap channel to prevent the subsequent workpiece from moving forward. Then, the push plate 12 carries the workpiece in its first dropping groove 15 forward together. When the first dropping groove 15 is completely aligned with the second dropping groove 16 on the fixed plate 14, the workpiece immediately falls accurately from the overlapping dropping groove under the action of gravity and enters the limiting groove of the lower support plate 6. After completing a single dropping, the linear cylinder 10 retracts and drives the push plate 12 to reset.
[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
