Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to an automatic carbon sheet riveting terminal attaching spring sheet machine. Background Technology

[0002] In the riveting of carbon fiber sheets and terminals, and the mounting of spring clips, many operations rely on manual labor in conjunction with single-process equipment. Terminal feeding requires manual lifting and placement one by one; positioning adjustments during carbon fiber sheet loading are cumbersome; and equipment changeovers for different specifications consume significant time. Manual handling of semi-finished products is prone to positioning deviations, leading to lower product yield rates. Riveting operations rely on manual pressure application, which is difficult to maintain evenly, often resulting in loose terminals or damaged carbon fiber sheets. Manual spring clip mounting can easily deform the clips, affecting the flatness of the mounting. Furthermore, the step-by-step operations require multiple people working together, resulting in low production efficiency, and the dispersed layout of various equipment occupies considerable space.

[0003] To address the aforementioned issues, this utility model document proposes an automatic carbon sheet riveting terminal attaching spring machine. Utility Model Content

[0004] This utility model provides an automatic carbon sheet riveting terminal and spring attaching machine, which solves the shortcomings of low assembly efficiency of carbon sheets, terminals and springs in the prior art.

[0005] This utility model provides the following technical solution: Automatic carbon fiber terminal riveting and spring attaching machine, including: The automatic carbon sheet riveting terminal and spring clip attaching machine body has a vibratory plate for automatically feeding terminal groups, a semi-automatic carbon sheet feeding fixture, an assembly fixture for assembling terminal groups and carbon sheets, a riveting mold for cutting terminals by stamping, and a spring clip attaching assembly installed sequentially on the top of the machine frame. The spring clip assembly includes a spring clip feeding fixture, a vacuum adsorption fixture for positioning the spring clip in the mold and applying the spring clip, and a pushing fixture that extends the semi-finished product through the extension and retraction of a cylinder for applying the spring clip and then retracts to complete the unloading. A pad is provided at the end of the frame, and a material collection box with an upward opening is provided on the top of the pad.

[0006] In one possible design, the vibratory feeder is fixed to the front end of the top of the frame by expansion bolts via a shock-absorbing base, and the height of the discharge port guide groove is adjusted to align it with the center line of the terminal positioning groove of the assembly fixture.

[0007] In one possible design, the semi-automatic carbon sheet feeding fixture is fixed between the vibratory feeder and the assembly fixture by positioning pins and bolts, ensuring that the carbon sheet pushing trajectory coincides with the carbon sheet receiving platform of the assembly fixture.

[0008] In one possible design, the assembly fixture is fixed at the top center of the frame, and the perpendicularity of the pressing head and the terminal positioning groove is calibrated by guide posts.

[0009] In one possible design, the riveting die is fixed to the rear of the assembly fixture by a die frame bolt, and the cutting edge and the riveting punch are synchronized by adjusting the gap between the upper die base and the lower die base.

[0010] In one possible design, the spring-loaded fixture is bolted to the left side of the vacuum suction fixture, the feed track outlet is aligned with the vacuum suction cup, the vacuum suction fixture is fixed to the top of the frame by a bracket, the positioning pin is aligned with the center line of the clamping block of the push fixture, the push fixture is fixed to the top end of the frame, and the extension and retraction direction of the push rod is aligned with the opening of the collection box.

[0011] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0012] The working principle and usage process of this technical solution are as follows: In use, terminal assemblies are placed in batches into the hopper of the vibratory feeder, and spring sheets are loaded into the tray of the spring sheet loading fixture. Compressed air and power are turned on, and equipment parameters (vibration frequency, cylinder pressure, stroke, etc.) are set via PLC. After the vibrator of the vibratory feeder starts, it drives the terminal assemblies in the hopper to move along the spiral feeding track. The orientation sorting mechanism corrects the placement direction of the terminal assemblies (ensuring the terminal connection ends face the assembly fixture). Qualified terminal assemblies are precisely fed into the terminal positioning slot of the assembly fixture through the discharge guide groove, and fixed by a magnetic suction mechanism. The operator places carbon sheets into the positioning slot of the semi-automatic carbon sheet loading fixture, and then... The push rod extends and retracts, sending the carbon sheet along the guide rail to the carbon sheet receiving platform of the assembly fixture. After the position sensor detects the carbon sheet, the pressing cylinder of the assembly fixture is activated, driving the pressing head to move downward along the guide column, pre-pressing and bonding the carbon sheet with the terminal group to complete the pre-assembly. The pre-assembled semi-finished product is sent to the positioning groove of the lower mold base of the riveting mold through the conveying mechanism (linked with the pressing cylinder). The stamping cylinder drives the upper mold base to descend rapidly, and the cutting edge first cuts off the excess connection part of the terminal group (the waste falls into the waste collection tank). Then, the riveting punch cooperates with the lower mold base to rivet and fix the terminal and carbon sheet, completing the core assembly. After riveting, the semi-finished product is driven by the telescopic cylinder of the push fixture. The push rod drives the clamping block to extend the semi-finished product to the bottom of the vacuum adsorption fixture. At the same time, the feeding track of the spring sheet feeding fixture sends the spring sheet to the separation mechanism. The pneumatic ejector separates one spring sheet at a time. The positioning block fixes the position of the spring sheet. The displacement cylinder of the vacuum adsorption fixture drives the adsorption seat to descend. The negative pressure generator is activated. The vacuum suction cup adsorbs the spring sheet. The displacement cylinder resets and moves laterally to the semi-finished product mounting position. The positioning pin is inserted into the positioning hole of the semi-finished product to correct the position. The vacuum suction cup releases the negative pressure and accurately mounts the spring sheet to the designated area of ​​the semi-finished product. After the spring sheet is mounted, the telescopic cylinder of the push fixture retracts. The push rod drives the finished product to move to the end of the frame. When it reaches the unloading position, the clamping block is released. The finished product falls into the collection box on the top of the pad under the action of gravity. The buffer pad in the box reduces the impact damage to the finished product, completing the entire production cycle.

[0013] This utility model has the following beneficial effects: This invention combines automation and flexibility. By adopting a combination of automatic terminal feeding via vibratory feeder and semi-automatic carbon sheet feeding, it reduces manual intervention, eliminates the need for manual placement of terminals, and adapts to the possible multi-specification requirements of carbon sheets. Manual feeding allows for quick switching of fixtures, which helps to solve the problems of cumbersome changeover in purely automated equipment and low efficiency in purely manual equipment. This utility model uses multiple positioning structures such as positioning pins, magnetic positioning, and guide columns to ensure the relative position accuracy of terminal groups, carbon sheets, and spring sheets. Stamping and riveting replace manual pressing, and the riveting force is uniform, avoiding loose terminals and carbon sheet damage. Vacuum adsorption is used to attach the spring sheets to prevent deformation, and the flatness of the attachment is better than that of manual operation. This utility model integrates five major processes: terminal feeding, assembly, cutting and riveting, attaching spring clips, and unloading. It eliminates the need for manual transfer of semi-finished products, resulting in a shorter cycle time. Compared with traditional step-by-step operations, manual transfer, and multi-equipment processing, it significantly improves efficiency and is suitable for mass production scenarios.

[0014] This utility model has a modular structure, and each fixture is detachable and replaceable. It is compatible with various specifications of carbon sheets, terminals, and springs, making maintenance convenient. The frame is equipped with an electrical protection chamber, and air pipes and wires are stored in the wiring trough to avoid tangling and interference. All moving parts (cylinders, push rods) are equipped with limit devices to prevent overtravel collisions and reduce operational risks. Attached Figure Description

The cutting edge first cuts off the excess connection part of the terminal group, and the waste material falls into the waste collection tank. Then the riveting punch cooperates with the lower mold base to rivet and fix the terminal and carbon sheet, completing the core assembly. After riveting, the semi-finished product is driven by the telescopic cylinder of the push fixture 9. The push rod drives the clamping block to extend the semi-finished product to the bottom of the vacuum adsorption fixture 8. At the same time, the feeding track of the spring sheet feeding fixture 7 sends the spring sheet to the separation mechanism. The pneumatic ejector separates one spring sheet at a time.
