Description

Technical Field

[0001] This application relates to the field of automated assembly technology, and in particular to a spring riveting assembly mechanism. Background Technology

[0002] In the spring manufacturing process, riveting and assembly is a crucial step, involving the precise assembly of the spring and the base plate. Traditional riveting and assembly processes rely heavily on manual operation, which is not only inefficient but also makes it difficult to guarantee assembly quality. With the continuous development of automation technology, various spring riveting and assembly mechanisms have emerged in the market, aiming to improve production efficiency and assembly accuracy.

[0003] Existing spring riveting and assembly mechanisms typically include basic components such as spring loading, assembly, inspection, and unloading, enabling automated processes for spring loading, assembly, inspection, and unloading. However, these mechanisms often encounter problems during operation, such as unstable spring loading, low assembly accuracy, and a lack of effective inspection methods. These issues not only affect spring production efficiency but may also lead to substandard product quality, increased production costs, and greater difficulty in subsequent maintenance.

[0004] Therefore, how to design a spring riveting and assembly mechanism that can solve the above problems and improve the production efficiency and assembly quality of springs has become an urgent technical problem to be solved in the current spring production field. Summary of the Invention

[0005] In order to improve the production efficiency and assembly quality of springs, this application provides a spring riveting assembly mechanism.

[0006] This application provides a spring riveting assembly mechanism, which adopts the following technical solution: A spring riveting assembly mechanism includes a spring feeding assembly, a spring seat assembly assembly, a reversing assembly, a discharging assembly, and a conveying guide rail. The conveying guide rail is characterized by the following features: the conveying guide rail is horizontally arranged; there are two sets of both the spring feeding assembly and the spring seat assembly assembly; the two sets of spring feeding assemblies are sequentially arranged at one end of the conveying guide rail; the discharging assembly is arranged at the other end of the conveying guide rail; and the spring seat assembly assembly, the reversing assembly, and the spring seat assembly assembly are sequentially arranged between the spring feeding assembly and the discharging assembly.

[0007] By adopting the above technical solution, the springs are automatically fed by the feeding assembly, assembled with the base plate by the spring seat assembly assembly, flipped by the reversing assembly, and finally inspected and unloaded by the unloading assembly. Throughout the process, all components work together to achieve automated production of spring riveting and assembly, improving production efficiency and product quality.

[0008] Optionally, the spring feeding assembly includes a worktable and a vibratory feeder. A support frame is vertically mounted on the worktable, and two material blocks for storing springs are connected to the support frame. The vibratory feeder contains several springs. Two conveyor pipes for transporting springs are connected to the top of each material block, and the other ends of the conveyor pipes are connected to the vibratory feeder. A discharge hole is opened at the bottom of each material block. A stop motor for controlling the sequential descent of the springs is installed inside each material block. A transport plate with through holes is located below each material block. A lifting cylinder is connected to the worktable, and a rotating mechanism is fixedly connected to the top of the lifting cylinder. The motor has a support plate fixedly connected to its output shaft. The support plate is horizontally positioned, and a base plate is located above it. The base plate is positioned at the through hole of the transport plate. Several mounting rods for mounting springs are vertically positioned on the upper surface of the base plate. The mounting rods are evenly distributed circumferentially. Two positioning holes are opened on the transport plate. A positioning cylinder is provided on the worktable. The positioning cylinder is vertically positioned on the worktable. A positioning plate is fixedly connected to the piston rod of the positioning cylinder. The positioning plate is horizontally positioned, and two positioning protrusions are fixedly connected to the top of the positioning plate. The two positioning protrusions are located at the two positioning holes.

[0009] By adopting the above technical solution and comprehensively utilizing components such as lifting cylinders, rotating motors, and mounting rods, the spring's dropping position and assembly posture can be precisely controlled, effectively solving problems such as spring misalignment and damage that exist in traditional feeding methods. Simultaneously, this equipment also boasts advantages such as simple structure, convenient operation, and low maintenance costs, providing strong support for the automation upgrade of the spring manufacturing and assembly industry. When installing springs, workers need to ensure the stability of the transport plate. At this time, the positioning cylinder is activated, causing the positioning plate to rise and fall, thereby causing the two positioning protrusions to clamp into the positioning holes, thus fixing the transport plate and improving structural stability.

[0010] Optionally, the spring seat assembly includes an operating table with a rotating disk on the operating table. The rotating disk is horizontally positioned, and a first motor is located at the bottom of the rotating disk. The output shaft of the first motor is coaxially and fixedly connected to the rotating disk. Four placement holes are evenly spaced on the rotating disk. Four material support plates are also provided on the rotating disk, each located above a placement hole. The material support plates hold the base plate material. A placement platform is located next to the rotating disk, and a lifting rod is connected to the placement platform. A moving block is slidably connected to the lifting rod, and a support rod is connected to the moving block. The support rod is located inside the placement hole. A mechanical gripper is provided between the operating table and the conveyor rail for moving the base plate material. A pressing frame is also provided above the conveyor rail, and a pressing cylinder is located at the top of the pressing frame. The piston rod of the pressing cylinder passes through the pressing frame and is connected to a pressing plate for assembling the spring and the base plate material.

[0011] By adopting the above technical solution, the bottom plate loading process can be automated, reducing manual operation and improving production efficiency. The cooperation between the conveyor and storage components enables continuous bottom plate supply, avoiding the waiting time and cumbersome operation of manual loading. The support plate on the rotating disc can hold the bottom plate raw materials. The rotation of the disc sequentially delivers different bottom plate raw materials to the loading position. The lifting and lowering of the support rod controls the movement of the bottom plate raw materials, facilitating subsequent loading operations. Then, mechanical grippers move the materials to the bottom of the pressing cylinder, where the pressing cylinder secures them.

[0012] Optionally, the reversing assembly includes a fixed gripper, a reversing plate, and a reversing motor. The reversing plate is provided with a drive screw, which extends along the length of the conveying guide rail. A lifting block is threadedly connected to the drive screw, and the lifting block is slidably connected to the fixed gripper. The reversing motor is located between the fixed gripper and the lifting block and is used to control the reversal of the fixed gripper.

[0013] By adopting the above technical solution, the workpiece can be flipped through the combined operation of the reversing motor, the fixed gripper, and the lifting block, thus facilitating the smooth implementation of subsequent processes.

[0014] Optionally, the unloading assembly includes an unloading platform, one side of which is provided with a force measuring component for measuring whether the force value of the component meets the requirements, and the other side is connected to a detection component for measuring whether the spring is correctly installed. A robotic arm for moving the elastic component back and forth is provided between the detection component and the force measuring component.

[0015] By adopting the above technical solution, when it is necessary to test the strength of elastic elements, the staff first uses a robotic arm to grip the elastic element to be measured, then places it on the force measuring component, then measures the force value of the elastic element through the force measuring component, and then uses the robotic arm to move the elastic element to the test component to check whether the spring is correctly installed. This realizes automated processing, reduces manpower consumption, and helps to improve work efficiency.

[0016] Optionally, the testing component includes a testing platform, on which a testing motor and a height sensor for measuring the height of the spring are provided. The testing motor is vertically mounted on the upper surface of the testing platform, and a rotating plate is fixedly connected to the output shaft of the testing motor. The rotating plate is horizontally mounted.

[0017] By adopting the above technical solution, when it is necessary to check whether a spring is installed correctly, the operator moves the elastic element to the rotating plate using a robotic arm, then obtains the spring height through a height sensor to determine whether the spring is installed correctly, and drives the detection motor. The detection motor drives the elastic element to rotate, thereby checking each spring in turn, realizing automated processing and improving work efficiency.

[0018] Optionally, the unloading platform is provided with a scrap pipe for collecting scrap parts on the side away from the conveyor belt. The scrap pipe is vertically arranged and the bottom end of the scrap pipe is connected to a scrap box.

[0019] By adopting the above technical solution, when the elastic element is qualified, it can be placed on the conveyor belt, and then the worker can remove the elastic element. When the elastic element is unqualified, the robotic arm will clamp the elastic element above the waste pipe and store it in the waste box for easy subsequent cleaning.

[0020] In summary, this application includes at least one of the following beneficial technical effects of the spring riveting assembly mechanism: 1. Because this invention adopts an automated process for spring loading, assembly, inspection and unloading, it significantly improves production efficiency and reduces manual operation costs; 2. The design of the spring seat assembly in this invention enables precise assembly of the spring and the base plate, improving product quality and assembly yield; 3. The force measuring and detection components in the feeding assembly can accurately detect the force value of the product and the spring installation status, ensuring that the product quality meets the standards.
