Description

Technical Field

[0001] This utility model relates to the field of automated feeding technology, specifically to a feeding device for a five-station pressure reducer assembly machine. Background Technology

[0002] The five-station pressure reducer assembly machine is a specialized piece of equipment for the automated assembly of pressure reducers. It typically adopts a rotary table layout, with multiple stations arranged in a ring to sequentially complete the core assembly processes of the pressure reducer. For example, station one is used for housing loading and positioning, station two for valve core pressing, station three for spring installation, station four for diaphragm assembly, and station five for closing and tightening the upper and lower housing covers. The continuous transfer of workpieces is achieved through the intermittent rotation of the rotary table. With the help of corresponding feeding devices, tooling fixtures, and testing mechanisms, the machine can automate the assembly of pressure reducers from parts to finished products, significantly improving production efficiency and assembly consistency.

[0003] In the feeding process of a five-station pressure reducer assembly machine, existing technologies mostly use manual picking or robotic arm gripping to transport parts. However, due to the different shapes and sizes of parts such as the pressure reducer housing, valve core, spring, and diaphragm, and the fact that they are often densely stacked in storage bins or conveyor tracks, forming a disordered stacking state, the end effector of the robotic arm has difficulty accurately identifying the position and posture of the target parts. During the gripping process, it is easily affected by interference from adjacent parts, resulting in jamming, misalignment, or gripping failure. At the same time, manual picking is not only limited by operating efficiency and fatigue, making it difficult to match the continuous cycle of the assembly machine, but also has low positioning accuracy, which can easily cause assembly deviation in subsequent stations.

[0004] Therefore, we propose a feeding device for a five-station pressure reducer assembly machine. Summary of the Invention

[0005] This utility model provides a feeding device for a five-station pressure reducer assembly machine. It features multiple material boxes within the machine's support frame, each containing two symmetrically arranged separation components. Guide plates and telescopic plates within these separation components are movably connected to the inner wall of the material box via support blocks. The rotation and extension of the guide plates and telescopic plates allow for the separation of parts within the material boxes, preventing dense, disordered stacking and reducing interference during robotic arm grasping. This improves positioning accuracy and solves the problems mentioned in the background art.

[0006] Existing feeding methods suffer from problems such as densely stacked parts, difficulty in robotic arm grasping and susceptibility to interference, and low efficiency and poor precision of manual handling, leading to subsequent assembly misalignment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding device for a five-station pressure reducer assembly machine includes an assembly machine body, a support is provided inside the assembly machine body, a plurality of material boxes are placed inside the support, and a separation component is provided inside the material boxes.

[0009] The separation component is used to divide the material box into upper and lower parts, and the separation component is used to control the sequential and orderly discharge of workpieces inside the material box.

[0010] Preferably, the separation component includes a guide plate, one end of which is provided with multiple support blocks, and the other end of the guide plate is movably connected to a telescopic plate. The end of the telescopic plate is provided with multiple support blocks, and the support blocks are fixedly connected to the inner wall of the material box. A rotating shaft is provided between the guide plate, the telescopic plate, and the support blocks.

[0011] Preferably, the telescopic plate includes a concave plate and a convex plate, which are interlocked and cross-connected. The end of the convex plate is provided with a protrusion and is movably connected to the inner groove of the concave plate. The concave plate is movably connected to the guide plate through a rotating shaft, and the convex plate is movably connected to multiple support blocks through a rotating shaft. The rotating shaft inside the support block passes through the material box and is fixedly connected to the end of the motor output shaft.

[0012] Preferably, the support includes a base plate, a baffle is fixedly connected to the end of the base plate, a support column is fixedly connected to the bottom of the baffle, and the support column is fixedly connected inside the assembly machine body.

[0013] Preferably, the base plate is inclined, the end of the base plate is provided with an arc hook shape, and multiple material boxes are placed on the top of the base plate.

[0014] Preferably, the baffle is a V-shaped plate, which serves to block falling parts while keeping the bottom of the parts on the baffle suspended in the air.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In a feeding device of a five-station pressure reducer assembly machine, the rotating shaft inside the support block is driven by a motor to rotate, which drives the guide plate and telescopic plate in the separation component to adjust their angles around the rotating shaft. When the two symmetrical separation components are shaped like a V downwards, they can guide the parts in the material box to move downwards one by one, realizing the orderly separation of the parts and avoiding disorderly stacking. When the telescopic plate is shaped like a V upwards, it can free up the space around a single part. With the cross-clamping telescopic structure of the concave plate and the convex plate, it can adapt to the separation requirements of parts of different sizes and solve the problem of parts stacking from the root.

[0017] 2. In a feeding device of a five-station pressure reducer assembly machine, the inclined design of the support base plate allows a single part guided by the separation component to slide down the guide plate on its own and finally fall to the V-shaped baffle. The baffle forms a stable block for the part while keeping the bottom of the part suspended in the air. When the robotic arm or a person grabs it, there is no need to push aside the surrounding parts, which greatly reduces grabbing interference. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figure 1 - Figure 7 The figure shows a feeding device for a five-station pressure reducer assembly machine, including an assembly machine body 1, and a support 2 inside the assembly machine body 1. The support 2 is characterized in that multiple material boxes 3 are placed inside the support 2, and a separation component 4 is provided inside the material box 3.

[0029] The separation component 4 is used to divide the material box 3 into upper and lower parts, and the separation component 4 is used to control the sequential and orderly discharge of workpieces inside the material box 3.

[0030] The separation component 4 includes a guide plate 41, one end of which is provided with multiple support blocks 42, and the other end of the guide plate 41 is movably connected to a telescopic plate 43. The end of the telescopic plate 43 is provided with multiple support blocks 42, and the support blocks 42 are fixedly connected to the inner wall of the material box 3. A rotating shaft 44 is provided between the guide plate 41, the telescopic plate 43 and the support blocks 42.

[0031] Therefore, it can be seen that when the feeding device of the five-station pressure reducer assembly machine is working, the bracket 2 inside the assembly machine body 1 provides installation support for multiple material boxes 3. The multiple material boxes 3 correspond to multiple workstations of the assembly machine to realize the classified storage and supply of parts. The two separate components 4 symmetrically arranged in each material box 3 work together. The working process relies on the linkage of guide plate 41, telescopic plate 43, support block 42 and rotating shaft 44: the motor drives the rotating shaft 44 inside the support block 42 to rotate. Since the guide plate 41 and telescopic plate 43 are movably connected to the support block 42 on the inner wall of the material box 3 through the rotating shaft 44, when the rotating shaft 44 rotates, it will drive the guide plate 41 and telescopic plate 43 to adjust the angle with the rotating shaft 44 as the fulcrum.

[0032] When the guide plates 41 and telescopic plates 43 of the two separation components 4 rotate downward to form a V shape, they can guide the parts in the material box 3, allowing the parts to move downward one by one along the guide plates 41. When the telescopic plates 43 rotate upward to form a V shape, they can clear the space around a single part, preventing the parts from stacking together. Through the angle adjustment and action coordination of the separation components 4, the orderly separation and conveying of parts can be achieved, providing convenience for subsequent gripping.

[0033] When implementing, refer to Figure 6 and Figure 7 As shown, the telescopic plate 43 includes a concave plate 430 and a convex plate 431, which are interlocked and cross-connected. The end of the convex plate 431 is provided with a protrusion, which is movably connected to the inner groove of the concave plate 430. The concave plate 430 is movably connected to the guide plate 41 through a rotating shaft 44, and the convex plate 431 is movably connected to multiple support blocks 42 through a rotating shaft 44. The rotating shaft 44 inside the support block 42 passes through the material box 3 and is fixedly connected to the end of the motor output shaft of the bracket 2.

[0034] The rotation of the motor output shaft drives the rotating shaft 44, which passes through the material box 3 and the bracket 2, to rotate synchronously. Since the convex plate 431 is movably connected to the support block 42 on the inner wall of the material box 3 through the rotating shaft 44, the rotation of the rotating shaft 44 will drive the convex plate 431 to swing at an angle with the rotating shaft 44 as the fulcrum. At the same time, the protrusion at the end of the convex plate 431 slides in the groove on the inner wall of the concave plate 430, so that the concave plate 430 can adapt to the swing of the convex plate 431.

[0035] It should be noted that the motor performs the following actions in a preset cycle: First, it drives the two separation components 4 to rotate downwards to a V-shape, guiding the parts to move down to the end of the telescopic plate 43; then it drives the separation components 4 to rotate upwards to a ∨-shape, at which point the bottom part falls alone due to gravity, while the upper parts are blocked by the ∧-shaped structure; the above steps are repeated to ensure that only one part is released in each action cycle.

[0036] When the convex plate 431 swings upward, the convex block slides along the groove towards the inside of the concave plate 430, increasing the cross-clamping length between the concave plate 430 and the convex plate 431, causing the telescopic plate 43 to retract as a whole; when the convex plate 431 swings downward, the convex block slides along the groove towards the outside of the concave plate 430, shortening the cross-clamping length between the concave plate 430 and the convex plate 431, causing the telescopic plate 43 to extend as a whole.

[0037] The concave plate 430 is movably connected to the guide plate 41 via the rotating shaft 44. The extension and angle change of the concave plate 430 will synchronously drive the guide plate 41 to adjust its angle with the rotating shaft 44 of its end support block 42 as the fulcrum. Finally, the guide plate 41 and the telescopic plate 43 of the separation component 4 work together to complete the ∨-shaped guidance and ∧-shaped air-lifting action, ensuring the orderly separation and conveying of the parts inside the material box 3.

[0038] Additionally, see Figure 3 and Figure 4 As shown, the support 2 includes a base plate 21, with a baffle 23 fixedly connected to one end of the base plate 21. A support column 22 is fixedly connected to the bottom of the baffle 23, and the support column 22 is fixedly connected inside the assembly machine body 1. The base plate 21 is inclined, and its end has an arc-shaped hook. Multiple material boxes 3 are placed on the top of the base plate 21. The baffle 23 is a V-shaped plate, which serves to block falling parts while keeping the bottom of the parts located on the baffle 23 suspended in the air.

[0039] The support frame 21 is fixedly connected to the assembly machine body 1 via the support column 22, providing stable support for the entire support frame 2. The base plate 21 is supported within the assembly machine body 1 via the support column 22, and multiple material boxes 3 placed on its top can be precisely aligned with the assembly machine station along with the support frame 2. Because the base plate 21 is inclined, combined with the arc hook design at the end, it can provide a stable foundation for the material boxes 3, and the inclined angle can assist the parts guided by the separation component 4 to slide along a preset path. When the parts slide from the separation component 4 in the material box 3 to the base plate 21, the inclined base plate 21 will guide the parts to move towards the end, and finally make them fall to the V-shaped baffle 23 fixedly connected to the end of the base plate 21. The V-shaped structure of the baffle 23 can form a stable block for the parts, preventing the parts from sliding excessively, and at the same time, it makes the bottom of the parts suspended, which is convenient for the robotic arm or manual grasping, avoids interference with other components during grasping, and ensures the smoothness and accuracy of the feeding process.
