Description

Technical Field

[0001] This invention relates to the field of automated assembly of spring coils, and in particular to a spring coil assembly machine. Background Technology

[0002] like Figure 29 As shown, the existing spring coil has an overall ring-shaped structure, including a spring coil body t1, a door seal t2, a torsion spring t3, and a rivet t4. The spring coil body t1 has an opening at one end, and both the spring coil body t1 and the door seal t2 have rivet holes at their heads. The two are hinged together by the rivet t4 through the rivet holes. The tails of the two form a normally closed switch that can be opened and closed. The closed loop that can be formed between the spring coil body t1 and the door seal t2 is an elastic buckle. The torsion spring t3 is installed between the spring coil body t1 and the door seal t2. The circle of the torsion spring t3 is fixed at the hinge of the spring coil body t1 and the door seal t2 by the rivet t4. Pressing the door seal t2 can compress the torsion spring t3 and rotate it relative to the spring coil body t1, thereby forming an opening between the spring coil body t1 and the door seal t2. After that, releasing the door seal t2 will allow it to return to its original shape under the action of the torsion spring t3.

[0003] Currently, in automated assembly equipment for spring coils, such as the Chinese invention patent application with application number CN202210827581.0 entitled "An Automatic Assembly Equipment for Spring Buckles," it includes a worktable and a turntable mechanism set on the worktable. The turntable mechanism has one or more evenly distributed fixtures. The worktable is equipped with a buckle feeding mechanism arranged along the rotation direction of the turntable mechanism for feeding buckles onto the fixtures, a spring assembly mechanism for feeding spring components onto the fixtures and pushing them into the buckle opening from one side, a fastening assembly mechanism for feeding fastening components onto the fixtures and pushing them into the second opening of the fastening component from one side, a fastening assembly mechanism for feeding pins onto the fixtures, a riveting mechanism for riveting spring buckles on the fixtures through pin holes, a discharge mechanism for discharging spring buckles from the fixtures, and a controller for controlling the above mechanisms. This equipment features a high degree of automation, fast assembly speed, and high assembly stability. Correspondingly, the process of automatically assembling spring rings using this tooling mold is also disclosed: the retaining ring is conveyed from the retaining ring feeding mechanism to the fixture, the retaining ring rotates along the turntable mechanism to the spring assembly mechanism station, the spring component is conveyed from the spring assembly mechanism to the fixture, and the spring component and retaining ring are initially assembled through the opening at one end of the retaining ring. After the spring assembly is completed, the fixture rotates along the turntable mechanism to the fastener assembly mechanism station, and the fastener assembly mechanism conveys the fastener to the fixture for the second step of assembly with the retaining ring and spring component. The fastener is pushed in so that the fastener is assembled from one side of the retaining ring, and the spring is assembled. The fixtures for the spring and fastening parts rotate along the turntable mechanism to the pin assembly mechanism station. The pin assembly mechanism delivers the pins to the pin holes on the spring for the third step of assembly. After the third step of assembly is completed, the fixture rotates along the turntable mechanism to the riveting mechanism station. The riveting mechanism rivets and fixes the spring with the assembled pins. After the spring is riveted and fixed, the fixture rotates along the turntable mechanism to the unloading mechanism station. The unloading mechanism pushes the spring out of the fixture to complete the unloading. Throughout the process, the spring, fastening parts, and buckles are all automatically fed and assembled, resulting in a high degree of automation in the assembly process.

[0004] However, because the buckle feeding mechanism uses a vibratory feeder to feed workpieces separately, it causes significant vibration of the assembly table. Each workpiece requires top-pressing of previously assembled workpieces onto the tooling mold during assembly; otherwise, the pre-arranged workpieces are prone to loosening or displacement. This can lead to misalignment between the torsion spring and the rivet hole during rivet insertion, increasing the failure rate of rivet assembly and significantly reducing the yield of assembled finished products, resulting in substantial waste or rework. The rivet assembly pressing mechanism needs to include a limiting device to prevent torsion spring displacement during rivet insertion. Furthermore, in existing technologies, the auxiliary assembly mechanism uses a large number of cylinders in its drive unit, resulting in high costs, complex control, and insufficient cylinder pressing power. Summary of the Invention

[0005] To address the aforementioned technical problems in existing automatic spring coil assembly equipment, this invention provides a more scientific and practical solution by adding auxiliary assembly mechanisms with specific functions. The technical solution adopted is as follows:

[0006] A spring coil assembly machine includes the following functional mechanisms:

[0007] Indexing rotary table mechanism, used to drive workpiece to rotate in process sequence, including indexing rotary table that can rotate in steps according to indexing angle;

[0008] The upper disc auxiliary assembly mechanism is vertically and flexibly mounted above the indexing rotary table mechanism. It is an auxiliary assembly mechanism for installing workpieces. It includes an upper disc and a crossbeam. The upper disc is located above the central area of ​​the indexing rotary table. The upper disc is mounted on the crossbeam and spans across the indexing rotary table mechanism together with the crossbeam.

[0009] The upper disc lifting mechanism is used to drive the upper disc auxiliary assembly mechanism to perform up and down lifting actions;

[0010] The tooling molds are arranged on the edge of the indexing rotary table according to the process sequence. One tooling mold corresponds to one process station and is used to fix the workpiece in the assembly.

[0011] The workpiece feeding device is located next to the indexing rotary table mechanism and is used to arrange and transport the various workpieces to be assembled to the side of the indexing rotary table. The workpiece feeding device includes a main feeding device, a torsion spring feeding device, a door seal feeding device, and a rivet feeding device arranged in a counterclockwise direction around the indexing rotary table mechanism.

[0012] The main assembly mechanism is located outside the indexing rotary table and is used to place the spring coil body from the main feeding device into the corresponding position of the tooling mold.

[0013] The outer side alignment mechanism is located on the outside of the indexing rotary table and on the right side of the main body assembly mechanism. It is used to guide the spring coil body assembled by the main body assembly mechanism from the side.

[0014] The main inspection mechanism is suspended outward from the edge of the indexing rotary table and is located on the right side of the main assembly mechanism. It is used to check whether the main body of the spring coil in the tooling mold is in place.

[0015] The torsion spring assembly mechanism is located outside the indexing rotary table, to the right of the top-alignment mechanism on the outside of the main body, and is used to place the torsion spring from the torsion spring feeding device onto the spring coil body of the tooling mold.

[0016] The torsion spring positioning detection mechanism is suspended outward on the crossbeam or the edge of the indexing rotary table, located on the right side of the torsion spring assembly mechanism, and is used to detect whether the torsion spring in the tooling mold is in place.

[0017] The door seal assembly mechanism is located outside the indexing rotary table and to the right of the torsion spring positioning detection mechanism. It is used to place the door seal from the door seal feeding device into the tooling mold and install it onto the spring coil body.

[0018] The door seal detection and alignment mechanism is suspended outward from the edge of the indexing rotary table and located on the right side of the door seal assembly mechanism. It is used to detect whether the door seal in the tooling mold is in place.

[0019] The rivet assembly mechanism is located outside the indexing rotary table and to the right of the door seal detection and alignment mechanism. It is used to insert the rivet into the coaxial hole of the spring coil body, torsion spring, and door seal.

[0020] The rivet inspection mechanism is suspended outwards from the edge of the indexing rotary table to detect whether the rivets are in place.

[0021] The rivet engagement mechanism, located to the right of the rivet detection mechanism, includes a stamping part and a riveting part. The stamping part is suspended outward from the crossbeam or the edge of the indexing rotary table for riveting rivets.

[0022] The finished product discharge mechanism is located outside the indexing rotary table and to the right of the rivet engagement mechanism, and is used for the classification and collection of finished products.

[0023] In use, the tooling molds of multiple spring coils are arranged in the indexing rotary table mechanism that rotates counterclockwise according to the process sequence, forming a multi-station cyclic process flow assembly line, and are continuously fed by the workpiece feeding device set on the periphery of the indexing rotary table.

[0024] In the workpiece auxiliary assembly mechanism, the main body detection mechanism, torsion spring positioning detection mechanism, door seal detection and alignment mechanism, and rivet detection mechanism are mounted on the upper disc auxiliary assembly mechanism and are driven by the upper disc lifting mechanism. The upper disc lifting mechanism is connected to the motor drive device through a synchronous pulley, thereby enabling the various functional mechanisms to lift and lower synchronously, replacing all cylinders. This ensures simultaneous lifting and lowering, and overcomes the various problems caused by the extensive use of cylinders, such as high cost, difficulty in control, and frequent malfunctions. Driven by the upper disc lifting mechanism, each functional mechanism switches up and down accordingly. When each functional mechanism is in the high position, the indexing rotary table rotates by one angle and advances one process station. Each process involves pressing the corresponding spring ring or spring ring component placed in the tooling mold to ensure that the spring ring body, door seal, torsion spring, rivets, and other components do not loosen during assembly. This also allows for a larger gap between the tooling mold and the spring ring, significantly increasing the tolerance for deformation of the spring ring blank, thereby reducing downtime and jamming caused by the quality of the spring ring blank. Then, each functional mechanism simultaneously performs its corresponding process for its respective task. If any abnormality is detected by the detection mechanism, an alarm is issued in conjunction with the controller. This cycle repeats continuously, forming a continuous automated assembly line for spring rings, greatly improving work efficiency.

[0025] As can be seen from the above, compared with the prior art, the present invention also has the following advantages: multi-process and multi-station operation is carried out simultaneously, and the positioning detection and assembly auxiliary clamping parts are completed simultaneously in the same lifting action, which greatly improves the working efficiency of automatic spring ring assembly; one lifting mechanism replaces multiple cylinders, which is low in cost, easy to control, and has fewer failures; the optimized rivet assembly top pressing mechanism presses the spring ring from the top, and at the same time applies the rear front pressing pressure to the torsion spring that is easy to loosen, thus limiting the loosening of the torsion spring; at the same time, it also improves the vibration resistance of the workpiece, has high assembly stability, and improves the yield rate.

By simultaneously performing multi-process, multi-station operations, positioning inspection and assembly auxiliary clamping parts are completed concurrently in the same lifting action, significantly improving the efficiency and reliability of automatic spring coil assembly. Replacing multiple cylinders with a single lifting mechanism reduces cost, simplifies control, and minimizes malfunctions. The optimized rivet assembly pressing mechanism presses down on the spring coil from the top while simultaneously applying rear-to-front pressure to the easily loosened torsion spring, limiting its loosening. This also improves the workpiece's vibration resistance, resulting in high assembly stability and a significantly increased yield rate for first-pass assembly.
