Description

Technical Field

[0001] This utility model relates to a stacking device, and more specifically, to a ring-shaped parts positioning stacking machine. Background Technology

[0002] Figure 1 This is a component of an electrical product. The part has an overall ring structure, namely a ring-shaped part 100, with a central hole 101 inside. Two inwardly protruding bosses 102 are provided on the inner wall of the central hole 101. This part is a plastic injection molded part. During the automated assembly process, it needs to be stacked and placed into an automatic feeding device. The automatic feeding device feeds it one by one to achieve positioning and assembly operations on an automated production line.

[0003] Currently, the stacking of such ring-shaped parts mainly relies on manual labor. During stacking, the position of the previous part needs to be aligned to achieve a consistent stacking angle, making the operation cumbersome and inefficient. To facilitate the positioning of individual parts, a common method is to vertically fix a positioning rod on the workbench. During stacking, each part is threaded onto the positioning rod for positioning, and after the stack is full, the entire stack is removed from the positioning rod. This method simplifies stacking to some extent, but it requires manual insertion of parts one by one from the top of the positioning rod, and then lifting them all together after the stack is full. This necessitates the operator raising their arms or bending over, resulting in high workload.

[0004] To facilitate the stacking of such ring-shaped parts, it is necessary to design a ring-shaped parts positioning and stacking machine to reduce the labor intensity of operators and improve production efficiency. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings of the existing technology and provide a ring-shaped parts positioning and stacking machine. By using the technical solution of this invention, a retractable positioning mandrel is used to enable the stacking operation to be completed on the stacking platform. After stacking, the stacked ring-shaped parts are pushed out along the slide by the pushing component. This solves the problem of high labor intensity caused by repeatedly picking up parts and putting them in from the top of the positioning mandrel in the existing technology. The operation process does not require frequent lifting of the arm, making the stacking operation easier and more convenient, and improving the product stacking efficiency.

[0035] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0036] [Example]

[0037] Combination Figures 2 to 4As shown, this embodiment of a ring-shaped parts positioning and stacking machine includes a frame 1, a worktable 2 mounted on the frame 1, a base plate 3, a stacking platform 4, a telescopic positioning rod assembly 5, a slide rail 6, and a pushing assembly 7. The worktable 2 is a large platform for placing ring-shaped parts 100 to be stacked. The base plate 3 is fixed to one side of the frame 1. The stacking platform 4 is located above the base plate 3, forming a stacking space between the stacking platform 4 and the base plate 3. The distance between the stacking platform 4 and the base plate 3 determines the stacking height. The stacking platform 4... The ring-shaped part 100 is attached to one side of the workbench 2 to facilitate the transfer of the ring-shaped part 100 on the workbench 2 to the stacking table 4 for stacking. The stacking table 4 is provided with a feeding hole 4-1, the size of which is slightly larger than the ring-shaped part 100 to be stacked, so that the ring-shaped part 100 can be inserted through the feeding hole 4-1. The telescopic positioning rod assembly 5 is installed below the base plate 3, and the telescopic positioning rod assembly 5 has a positioning core rod 5-1 that can move up and down in the stacking space and is positioned opposite to the feeding hole 4-1. During the stacking operation, The positioning mandrel 5-1 rises, moving its upper end into the feed hole 4-1. At this time, the center of the feed hole 4-1 has the positioning mandrel 5-1, allowing the annular part 100 to be placed onto the positioning mandrel 5-1 through the feed hole 4-1. After a set number of annular parts 100 are placed on the positioning mandrel 5-1, the telescopic positioning rod assembly 5 moves the positioning mandrel 5-1 downward, so that the upper end of the positioning mandrel 5-1 is lower than the upper plane of the base plate 3, facilitating the subsequent ejection of stacked parts together. The slide 6 is located between the stacking platform 4 and the base plate. Between plates 3 and below the inlet hole 4-1, the slide 6 can guide and limit the stacked parts, preventing them from tilting to one side after the positioning core 5-1 is no longer restrained. The pusher assembly 7 is located at one end of the slide 6 and is used to push the stacked annular parts 100 along the slide 6. After the positioning core 5-1 descends, the stacked parts are no longer restrained by the positioning core 5-1. At this time, the pusher assembly 7 can push the parts along the slide 6, making it easy to transfer to the next station. Using the above-mentioned annular part positioning stacking machine, the retractable positioning core 5-1 allows the stacking operation to be completed on the stacking table 4. After stacking, the pusher assembly 7 pushes the stacked annular parts 100 along the slide 6, solving the problem of high labor intensity caused by repeatedly picking up parts from the top of the positioning core and putting them in. The operation process does not require frequent lifting of the arm, making the stacking operation easier and more convenient, which is conducive to improving the product stacking efficiency.

[0038] like Figure 2As shown, in this embodiment, the upper surface of the stacking platform 4 is flush with the upper surface of the worktable 2; or, the upper surface of the stacking platform 4 is slightly lower than the upper surface of the worktable 2. This allows the annular parts 100 on the worktable 2 to be directly pushed onto the stacking platform 4, facilitating the transfer of parts from the worktable 2 to the stacking platform 4, making operation simpler and more convenient. Furthermore, the stacking platform 4 is fixed to the base plate 3 by columns 4-2. Preferably, four columns 4-2 are provided, distributed at the four corners of the stacking platform 4, ensuring the stacking platform 4 is firmly fixed and guaranteeing the reliability of the stacker machine.

[0039] like Figures 3 to 5 As shown, in this embodiment, the telescopic positioning rod assembly 5 further includes a telescopic cylinder 5-2, a guide post 5-3, a fixed plate 5-4, and a lifting plate 5-5. The fixed plate 5-4 is fixedly installed below the base plate 3 via the guide post 5-3. The lifting plate 5-5 is slidably installed on the guide post 5-3. The telescopic cylinder 5-2 is installed on the fixed plate 5-4, and the driving end of the telescopic cylinder 5-2 is fixedly connected to the lifting plate 5-5 to drive the lifting plate 5-5 to move up and down. The lower end of the positioning mandrel 5-1 is fixed on the lifting plate 5-5. Two guide posts 5-3 are provided in parallel. A guide sleeve that slides with the guide post 5-3 is also provided on the lifting plate 5-5. The telescopic cylinder 5-2 can drive the lifting plate 5-5 to slide up and down on the guide post 5-3, thereby driving the positioning mandrel 5-1 to move up and down. The lifting stroke of the telescopic cylinder 5-2 is greater than the distance between the base plate 3 and the stacking platform 4, so that the upper end of the positioning mandrel 5-1 can move below the upper surface of the base plate 3. The aforementioned telescopic cylinder 5-2 drives the positioning mandrel 5-1 to move up and down, and the guide post 5-3 serves as a guide, ensuring the stable movement of the positioning mandrel 5-1 and guaranteeing its positioning accuracy. Furthermore, the cross-sectional shape of the positioning mandrel 5-1 is adapted to the shape of the central hole 101 of the annular part 100, ensuring the consistency of the stacking direction of the annular parts 100 and providing a stable feeding guarantee for subsequent automated assembly.

[0040] catch Figures 3 to 5 As shown, in this embodiment, the slide 6 is composed of two parallel baffles 6-1. One end of the baffle 6-1 extends to both sides below the inlet hole 4-1, which can provide lateral restraint for the stacked annular parts 100. The slide 6 is formed by the baffles 6-1, which has a simple structure and is easy to manufacture. In addition, the above-mentioned pushing assembly 7 includes a pushing cylinder 7-1 and a pushing plate 7-2. The pushing cylinder 7-1 is fixedly installed on the base plate 3, and the pushing plate 7-2 is vertically fixed on the driving end of the pushing cylinder 7-1. The moving direction of the pushing plate 7-2 is consistent with the direction of the slide 6. The pneumatic pushing design ensures stable pushing action and can quickly push out the stacked parts together, facilitating their transfer to other processes.

[0041] Reference Figure 2and Figure 3 As shown in the figure, a ring-shaped parts positioning and stacking machine of this embodiment has two feeding holes 4-1 on the stacking platform 4, and a telescopic positioning rod assembly 5, a slide rail 6, and a pushing assembly 7 respectively provided on the base plate 3 to cooperate with the corresponding feeding holes 4-1, forming a dual-station stacking mechanism. The dual-station design can improve stacking efficiency.

[0042] The following is based on Figure 1 Taking the annular part 100 shown as an example, the working principle of the annular part positioning and stacking machine of this utility model is further explained.

[0043] An annular part 100 is placed on the worktable 2. The annular part 100 has a boss 102 inside its central hole 101. Correspondingly, positioning grooves 5-1a, adapted to the boss 102, are also provided on both sides of the positioning mandrel 5-1. (Refer to...) Figure 2 and Figure 4 As shown, during the stacking operation, the telescopic cylinder 5-2 drives the positioning mandrel 5-1 to rise, so that the upper end of the positioning mandrel 5-1 is located in the feed hole 4-1. The operator pushes the annular part 100 on the workbench 2 onto the stacking table 4, adjusts the angle, and aligns it with the feed hole 4-1 to place it into the positioning mandrel 5-1. Since the upper surface of the stacking table 4 is close to the height of the upper end of the positioning mandrel 5-1, there is no need to frequently raise the arm. When the positioning mandrel 5-1 is fully fitted with the annular part 100, the telescopic cylinder 5-2 is controlled to drive the positioning mandrel 5-1 to fall, so that the upper end of the positioning mandrel 5-1 moves below the upper surface of the base plate 3, releasing the constraint of the positioning mandrel 5-1 on the annular part 100. Then, the pushing cylinder 7-1 drives the pushing plate 7-2 to move, pushing the stacked annular parts 100 out along the slide 6, whereby the operator can place them into other workstations.

[0044] This utility model discloses a ring-shaped parts positioning and stacking machine. It utilizes a retractable positioning mandrel, which allows the stacking operation to be completed on the stacking platform. After stacking, the stacked ring-shaped parts are pushed out along the slide by the pushing component. This solves the problem of high labor intensity caused by repeatedly picking up parts and putting them in from the top of the positioning mandrel in the existing technology. The operation process does not require frequent lifting of the arm, making the stacking operation easier and more convenient, and helping to improve the product stacking efficiency.

[0045] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
