Description

Technical Field

[0001] This utility model relates to the field of automated production technology of hardened products, and in particular to an automatic spring assembly mechanism. Background Technology

[0002] In the fields of injection molding and plastic product assembly, with the continuous improvement of industrial automation, enterprises have an increasingly urgent need for efficient, stable, and low-cost automated assembly equipment. Especially in the production of plastic parts that include spring assembly, traditional manual operation methods are no longer sufficient to meet the requirements of large-volume, high-rate-of-production. Therefore, developing a dedicated mechanism capable of automatically gripping, positioning, and assembling springs has become a key technological direction for improving production line automation and reducing reliance on manual labor.

[0003] In existing technologies, common spring assembly methods often employ simple robotic arms in conjunction with manual loading. These arms typically consist of a basic gripper cylinder, a linear module, and a simple positioning platform. The robotic arm uses pneumatic or electric drive to open and close the gripper, picking up the spring and moving it along a guide rail above the product. Coarse positioning is then performed manually or using simple sensors, followed by a pushing mechanism that presses the spring into the product's hole.

[0004] However, the existing technologies mentioned above have significant shortcomings in the spring clamping process: due to the elasticity and easily deformable shape of springs, traditional pneumatic grippers are prone to problems such as insecure clamping, positional misalignment, or spring bouncing and falling off during the gripping process, resulting in the spring not being accurately and stably delivered to the predetermined position. This problem not only affects the assembly success rate but also leads to an increase in product defect rate and a decrease in production cycle time, severely restricting the operating efficiency and reliability of automated assembly lines. Therefore, an automatic spring assembly mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic spring assembly mechanism, which aims to improve the problem that the existing spring assembly methods mostly use simple robotic arms in conjunction with manual feeding, which seriously restricts the operating efficiency and reliability of automated assembly lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic spring assembly mechanism includes a guide rail and a connecting plate. A support assembly is provided on the top of the guide rail. A second cylinder is fixedly connected to the top of the support assembly. A push block is fixedly connected to the output end of the second cylinder. A push assembly is provided on the side wall of the push block.

[0008] The pushing component includes a pushing plate, one side of which is fixedly connected to the side wall of the pushing block. A cylinder is fixedly connected to the top of the support component. An upper clamping block and a lower clamping block are fixedly connected to the output end of the cylinder. Clamping components are provided on the side walls of the upper and lower clamping blocks. A limit component is provided inside the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The support assembly includes a support platform that is slidably connected to the top of the guide rail.

[0011] As a further description of the above technical solution:

[0012] The clamping assembly includes an upper clamping plate and a lower clamping plate. The side wall of the upper clamping plate is fixedly connected to the side wall of the upper clamping block, and the side wall of the lower clamping plate is fixedly connected to the side wall of the lower clamping block.

[0013] As a further description of the above technical solution:

[0014] The bottom of the upper clamping plate is in contact with the top of the spring, and the top of the lower clamping plate is in contact with the bottom of the spring.

[0015] As a further description of the above technical solution:

[0016] The limiting component includes a blocking block, the outer wall of which is fixedly connected to the inner wall of the connecting plate.

[0017] As a further description of the above technical solution:

[0018] A blocking plate is fixedly connected to the side wall of the blocking block, and a product is disposed between the blocking plate and the pushing plate.

[0019] This utility model has the following beneficial effects:

[0020] The system utilizes cylinder one to drive the upper and lower clamping blocks, which in turn move the upper and lower clamping plates to contact the spring, ensuring stable clamping and resolving the issues of spring loosening and misalignment during manual clamping, thus improving the reliability of spring clamping. Subsequently, a guide rail supports the sliding support platform, causing cylinders one and two on the support platform and the clamping components to move forward, bringing the spring closer to the product. Simultaneously, a blocking block within the connecting plate moves the blocking plate, precisely limiting the product's position and resolving the issue of large deviations in manual product positioning, thus improving the accuracy of product positioning. Cylinder two then drives the pushing block, which in turn moves the pushing plate to push the spring into the product, automating the spring assembly process. The entire system requires only one operator, replacing traditional multi-person manual operations, reducing labor costs and addressing the issue of high labor costs. Furthermore, automated cyclical operation avoids the efficiency fluctuations and errors of manual operation, improving production efficiency and the consistency of spring assembly, enhancing production stability, and adapting to the needs of automated plastic parts production.

[0029] 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.

[0030] Reference Figure 1 - Figure 6 The present invention provides an embodiment of an automatic spring assembly mechanism, comprising a guide rail 1 for supporting and guiding the linear motion of the entire mechanism, a connecting plate 8 for installing and fixing limiting components, a support component on the top of the guide rail 1 for bearing and connecting various actuators, a cylinder 4 fixedly connected to the top of the support component for providing a power source for pushing action, a push block 7 fixedly connected to the output end of the cylinder 4 for transmitting the thrust of the cylinder, and a push component on the side wall of the push block 7 for directly pushing the spring to complete the assembly.

[0031] The pushing assembly includes a pushing plate 13 for contacting and pushing the spring into the product 10. One side of the pushing plate 13 is fixedly connected to the side wall of the pushing block 7 to realize power transmission. The top of the support assembly is fixedly connected to a cylinder 3 to provide the power source for the clamping action. The output end of the cylinder 3 is fixedly connected to an upper clamping block 5 and a lower clamping block 6 to drive the clamping assembly to perform the clamping action. The side walls of the upper clamping block 5 and the lower clamping block 6 are both provided with clamping components for directly clamping the spring.

[0032] The clamping assembly includes an upper clamping plate 11 and a lower clamping plate 12, which are used to contact the top and bottom of the spring respectively to achieve stable clamping. The side wall of the upper clamping plate 11 is fixedly connected to the side wall of the upper clamping block 5, and the side wall of the lower clamping plate 12 is fixedly connected to the side wall of the lower clamping block 6. The bottom of the upper clamping plate 11 contacts the top of the spring to prevent the spring from falling off during movement, and the top of the lower clamping plate 12 contacts the bottom of the spring to provide a stable clamping force. The connecting plate 8 is provided with a limit component for precise positioning of the product 10.

[0033] The limiting component includes a blocking block 9 for mounting and fixing a blocking plate 14. The outer wall of the blocking block 9 is fixedly connected to the inner wall of the connecting plate 8 to provide a stable structural connection. The side wall of the blocking block 9 is fixedly connected to the blocking plate 14 for directly blocking and positioning the product 10. The product 10 is disposed between the blocking plate 14 and the push plate 13 to form the target position for spring assembly.

[0034] Working principle: Cylinder 3 drives the upper clamping block 5 and the lower clamping block 6 to move towards each other, which in turn drives the upper clamping plate 11 fixed to the side wall of the upper clamping block 5 and the lower clamping plate 12 fixed to the side wall of the lower clamping block 6 to move synchronously, so that the bottom of the upper clamping plate 11 is in close contact with the top of the spring, and the top of the lower clamping plate 12 is in close contact with the bottom of the spring, thus achieving stable clamping of the spring. Then, the support platform 2, which is slidably connected to the top of the support platform 1, is guided by the guide rail 1, which drives the support platform 2 to slide forward along the top of the guide rail 1, thereby driving the cylinders 3 and 4 fixed to the top of the support platform 2, as well as the upper clamping plate 11 that has clamped the spring. The lower clamping plate 12 moves forward synchronously until the spring approaches the area of ​​the connecting plate 8. At the same time, the blocking block 9, which is fixedly connected to the inner wall of the connecting plate 8, drives the blocking plate 14 on its side wall to remain fixed, so that the product 10 between the blocking plate 14 and the push plate 13 is precisely limited, preventing the product 10 from shifting. Then, the cylinder 2 4 drives the push block 7, which is fixed at its output end, to move forward, thereby driving the push plate 13, which is fixed on the side wall of the push block 7, to move forward synchronously. This allows the push plate 13 to push the spring, which has been stably clamped, and precisely push the spring into the limited product 10, completing the reset of each component after the spring is inserted.
