Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to a rubber gasket auxiliary assembly device. Background Technology

[0002] Currently, control boxes require rubber gaskets for cushioning and sealing. Typically, the control box has mounting holes for these gaskets. The special structural design of the rubber gasket, with its central annular step, results in the diameters at the top and bottom being significantly larger than the central diameter. This structural feature presents significant challenges to the assembly process: firstly, to ensure post-assembly stability, the width of the mounting hole must be smaller than the maximum outer diameter of the rubber gasket; secondly, this dimensional difference necessitates applying considerable external force to deform the rubber gasket before it can be squeezed into the mounting hole. Traditional manual assembly methods are not only inefficient and prone to operator fatigue, but also struggle to guarantee consistent assembly quality. The drawbacks of manual assembly are particularly pronounced in mass production environments, including slow assembly speed, high labor intensity, and difficulty in controlling product yield. Furthermore, different specifications of rubber gaskets require different assembly forces, which are difficult to accurately apply manually, easily leading to gasket damage or improper assembly. These problems severely restrict the improvement of production efficiency and the stability of product quality. Utility Model Content

[0016] Combination Figures 1 to 3 As shown, this embodiment provides a rubber gasket auxiliary assembly device, including: a base 1, on which a straight groove 11 suitable for placing a rubber gasket 4 is formed; a guide pre-compression structure 2 is provided at one end of the straight groove 11, the guide pre-compression structure 2 is located at the opening at the end of the straight groove 11, and a guide opening 22 is formed for the rubber gasket 4 to pass through; the guide opening 22 is adapted to communicate with the mounting hole of the target box, and the width of the guide opening 22 is less than or equal to the width of the mounting hole; a pushing device 3 is provided at the other end of the straight groove 11, the pushing device 3 is adapted to push the rubber gasket 4 placed in the straight groove 11 toward the guide pre-compression structure 2, and cause the rubber gasket 4 to deform at the guide pre-compression structure 2 to pass through the guide opening 22 and enter the mounting hole of the target box.

[0017] The linear groove 11 refers to a groove structure extending along the surface of the base 1, used to accommodate and guide the linear movement of the rubber gasket 4. Specifically, it can be implemented using a rectangular or U-shaped cross-section groove, with its length and width adjusted according to the gasket size. The guide pre-compression structure 2 refers to a limiting component located at the groove outlet, which compresses and guides the gasket through the guide opening 22. For example, an adjustable guide block 21 forms a variable-opening guide channel, ensuring that the gasket gradually deforms to the size that allows it to pass through the mounting hole during movement. The pushing device 3 refers to a driving component that provides linear thrust, such as a cylinder working in conjunction with the pushing block 32. As the pushing block 32 moves along the groove, it smoothly pushes the gasket into the guide pre-compression area. After the rubber gasket 4 is placed in the linear groove 11, the pushing device 3 is activated and drives the pushing block 32 to move along the groove towards the guide pre-compression structure 2. Under the action of the pushing force, the gasket slides along the groove. When it reaches the guide opening 22, it is squeezed by the guide structures on both sides, and its outer diameter is compressed to be less than or equal to the width of the mounting hole, thus smoothly passing through the guide opening 22 and embedding into the mounting hole of the target housing. The width limitation of the guide port 22 ensures that the washer completes the necessary deformation before entering the mounting hole, avoiding assembly failure due to size mismatch.

[0018] This solution achieves automatic alignment and controllable deformation of the gaskets through a mechanized guiding pre-compression structure 2 and a pushing device 3, reducing manual intervention while improving assembly accuracy and efficiency. The adjustable design of the guide port 22 further enhances the mechanism's adaptability to gaskets of different sizes. It enables rapid and stable assembly of the rubber gaskets 4, avoiding fatigue and errors caused by manual operation. The guiding pre-compression structure 2 ensures that the gasket completes precise deformation before entering the mounting hole, and the pushing device 3 provides continuous and uniform thrust, thereby significantly improving assembly efficiency and reducing the defect rate. This mechanism is particularly suitable for mass production scenarios, effectively solving the problems of slow speed and poor consistency in traditional assembly methods.

[0019] In this embodiment, the guide preloading structure 2 includes two guide blocks 21 located on both sides of the end opening of the linear slide groove 11. The guide blocks 21 are adjustable in position on the base 1 to adjust the opening of the guide opening 22 formed between them, so as to accommodate rubber gaskets 4 with different outer diameters. The two guide blocks 21 extend from opposite sides of the linear slide groove 11 into a portion of the linear slide groove 11 to form the guide opening 22. The guide blocks 21 refer to the limiting components located on both sides of the slide groove opening. They can be implemented using a slider structure with adjusting bolts. The width of the guide opening 22 can be controlled by changing the fixed position of the slider on the base 1. The adjustable position means that the guide blocks 21 and the base 1 form a movable connection relationship. Specifically, this can be achieved by using a slide rail and a positioning hole. For example, a long strip-shaped slide groove can be provided on the base 1 for the bottom of the guide blocks 21 to slide. The two guide blocks 21 are respectively installed on the two sides of the end opening of the linear slide groove 11. By adjusting the relative position of the guide blocks 21 along the length of the slide groove, the width of the guide opening 22 formed between them can be changed. When rubber washers 4 with different outer diameters need to be assembled, the guide block 21 can be moved to the corresponding position so that the width of the guide opening 22 matches the outer diameter of the target rubber washer 4. Under the action of the pushing device 3, the rubber washer 4 is compressed and deformed as it passes through the guide opening 22. The amount of deformation is precisely controlled by the width of the guide opening 22, thereby ensuring smooth entry into the mounting hole. Through the movable guide block 21 structure, the size of the guide opening 22 can be quickly adjusted without replacing parts, effectively solving the compatibility problem of assembling multi-specification products.

[0020] In a preferred embodiment, the guide opening 22 is configured as a figure-eight shaped opening with a gradually decreasing opening along the movement direction of the rubber washer 4. The guide opening 22 is achieved through the gap formed between two symmetrically distributed guide blocks 21, the width of which gradually decreases along the movement direction of the rubber washer 4, thereby guiding the rubber washer 4 to gradually deform to adapt to the size of the mounting hole. The figure-eight shaped opening refers to a symmetrical structure where the gap between the two guide blocks 21 is wider at the inlet and narrower at the outlet. This can be achieved by adjusting the tilt angle or relative position of the guide blocks 21, or by setting the shape of the guide blocks 21. This structure allows the rubber washer 4 to be compressed uniformly during movement, avoiding localized stress concentration. When the pushing device 3 pushes the rubber washer 4 along the linear groove 11 towards the guide pre-compression structure 2, the rubber washer 4 first contacts the inlet end of the figure-eight shaped opening. At this time, the opening is relatively large, and the rubber washer 4 begins to undergo initial deformation. As the pushing device 3 continues to act, the rubber washer 4 gradually enters the region where the opening gradually narrows. Its outer diameter is squeezed by the guide blocks 21 on both sides until the deformed size matches the width of the mounting hole, and finally it smoothly passes through the guide opening 22 and enters the mounting hole of the target box. During this process, the gradual compression characteristics of the "eight"-shaped opening make the deformation process of the rubber washer 4 smoother, reducing the assembly resistance or washer damage risk caused by sudden compression. By completing the deformation process of the rubber washer 4 in stages, the thrust required for assembly is reduced, and the uniformity of deformation is improved.

[0021] In another preferred embodiment, the top surface of the guide block 21 is provided with a guide slope 211 that slopes upwards along the direction of movement of the rubber washer 4. The guide slope 211 refers to the surface on the top surface that slopes upwards; it can be a flat surface or a slightly curved surface, with an inclination angle, for example, between 10 and 30 degrees, to guide the rubber washer 4 to gradually deform under pressure and smoothly enter the mounting hole, reducing movement resistance. When the pushing device 3 pushes the rubber washer 4 towards the guide opening 22, the guide slope 211 contacts the rubber washer 4, causing it to be guided in the direction of movement by the sloped surface, gradually compressing and deforming, thus smoothly passing through the guide opening 22 and entering the mounting hole. The slope design ensures a smooth deformation process, avoiding jamming or rebound caused by sudden force. For example, after the rubber washer 4 contacts the guide slope 211, the larger diameter portions at its upper and lower ends will gradually converge along the slope until it passes through the guide opening 22 and enters the mounting hole. The sloping design makes the compression deformation of the rubber gasket 4 gradual, which reduces assembly resistance and avoids material damage caused by local stress concentration.

[0022] It is important to note that in this embodiment, the thickness of the guide block 21 is less than or equal to the height of the annular step of the rubber washer 4. The thickness of the guide block 21 refers to its dimension in the direction perpendicular to the extension of the linear groove 11. This thickness limitation ensures that the guide block 21 does not excessively interfere with the compression space of the annular step when guiding the deformation of the rubber washer 4. The height of the annular step of the rubber washer 4 refers to the depth of the recessed area in the middle of the rubber washer 4 in the vertical direction, which determines the deformation of the rubber washer 4 during compression. When the pushing device 3 pushes the rubber washer 4 along the linear groove 11 towards the guide pre-compression structure 2, the annular step area of ​​the rubber washer 4 will deform due to the compression of the guide opening 22. This allows the rubber washer 4 to maintain a stable deformation path when passing through the guide opening 22, preventing the annular step from being accidentally blocked or stuck due to excessive thickness of the guide block 21. This reduces the assembly failure rate and improves the efficiency of automated assembly.

[0023] The pushing device 3 described in this embodiment includes a pushing cylinder 31 and a pushing block 32 connected to the output end of the pushing cylinder 31. The pushing block 32 is adapted to move linearly along the linear slide 11 to push the rubber washer 4 toward the guide port 22. The pushing block 32 is connected to the pushing cylinder 31 through a connecting block 34. The connecting block 34 is provided with a slot 341 for the push rod inside the pushing cylinder 31 to be embedded and connected. The pushing block 32 and the connecting block 34 can be configured as one unit. During installation, the pushing block 32 and the connecting block 34 are first installed above the linear slide 11, and then the pushing guide structure 33 is installed.

[0024] The push cylinder 31 is an actuator that generates linear motion power through compressed air, and its output end is mechanically connected to the connecting block 34 via a push rod. The push block 32 is a pushing component that directly contacts the rubber washer 4, and its bottom shape can match the contour of the linear slide groove 11. This structure ensures that the rubber washer 4 maintains a predetermined posture during the pushing process, preventing displacement and uneven deformation. The slot 341 is a mechanical interface provided on the connecting block 34, which can be implemented using a T-slot structure, allowing the end of the push rod to be embedded and secured. This design facilitates quick disassembly and maintenance while ensuring reliable power transmission. When the push cylinder 31 is activated, the push rod drives the connecting block 34 to move linearly through the slot 341, and the push block 32, which is integrally formed with the connecting block 34, moves along the linear slide groove 11. After the front end of the push block 32 contacts the rubber washer 4, a continuous pushing force is applied, causing it to slide towards the guide preload structure 2.

[0025] In a preferred embodiment, a push guide structure 33 is provided above the linear slide 11 to maintain the stability of the linear movement of the push block 32. The push guide structure 33 is detachably mounted on the base 1 by bolts and forms an active guide space for the push block 32.

[0026] The push guide structure 33 refers to a limiting component positioned above the linear slide groove 11 and corresponding to the movement trajectory of the push block 32. Specifically, it can be implemented using a metal frame with a guide slide groove 331. Its function is to physically constrain the movement direction of the push block 32, preventing it from deviating during the pushing process. Furthermore, a guide rib 321 is provided on the top surface of the push block 32, and a guide slide groove 331 adapted to the guide rib 321 is formed on the inner side of the push guide structure 33. The guide rib 321 refers to a protruding structure extending along the movement direction of the push block 32. For example, it can be implemented by welding a trapezoidal cross-section metal strip to the top surface of the push block 32. This structure forms a stable sliding pair through its cooperation with the guide slide groove 331.

[0027] Specifically, during the assembly of the rubber gasket 4, when the push cylinder 31 drives the push block 32 to move along the linear slide groove 11, the guide rib 321 is embedded inside the guide slide groove 331 to form a dual guiding mechanism. This structure effectively prevents the push block 32 from tilting or deviating during movement by dispersing the lateral load through the contact surface between the rib and the slide groove when the push block 32 bears the reaction force of the rubber gasket 4. The length of the guide slide groove 331 can be set to cover the entire stroke of the push block 32, ensuring stable guidance during the critical stage of pre-compression deformation of the rubber gasket 4.

[0028] Through the above technical solution, this application effectively solves the problem of movement trajectory deviation caused by uneven force during the pre-press assembly of the push block 32 in the rubber gasket 4. The cooperation structure between the guide rib 321 and the guide groove 331 improves the movement accuracy of the push block 32 in the linear groove 11. The deformation consistency of the rubber gasket 4 during the assembly process is improved, avoiding assembly failure or part damage caused by the skewness of the push block 32.

[0029] In a preferred embodiment, an optical fiber sensor 5 is provided on one side of the base to detect whether there is a rubber gasket 4 in the linear chute, in order to prevent empty material operation.

[0030] The solution in this embodiment improves the installation efficiency of the rubber gasket 4, and it is applicable to various specifications of rubber gaskets 4, showing good versatility.

[0031] It should be understood that the above are only preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
