Description

Technical Field

[0001] This utility model relates to the field of switch assembly technology, specifically to an automatic assembly machine for terminal components of a ship-shaped overload protection switch. Background Technology

[0002] In existing technologies, the assembly of ship-type overload protection switches largely relies on manual operation. Operators typically need to manually pick up, align, and press numerous small, precision components such as springs, terminals, and buttons one by one into the housing base. This process is not only tedious and inefficient, but also demands a high level of skill and concentration from the operator. Due to the small size and compact structure of the parts, manual assembly is prone to quality defects such as omissions, incorrect installations, or improper placement, making it difficult to guarantee product qualification rates. At the same time, the ever-increasing labor costs also place enormous pressure on production. Utility Model Content

[0021] The technical solution of this utility model has the following advantages:

[0022] 1. The automatic terminal assembly machine provided by this utility model integrates the two core processes of bimetallic terminal riveting and spring assembly bending into one machine, realizing the fully automated production process from parts to sub-assemblies. The process of riveting first, then inserting, and then bending can effectively ensure the accuracy of the bimetallic strip and spring insertion and the stability of the bending angle, thereby ensuring the consistency of the quality and performance of the final assembled product.

[0023] 2. The automatic assembly machine for terminal components provided by this utility model includes a bimetallic terminal riveting device comprising a first turntable, a first terminal feeding mechanism, a terminal clamping mechanism, a bimetallic sheet feeding mechanism, a riveting mechanism, and a first material transfer mechanism. Before riveting, the first terminal is clamped onto the fixture to prevent displacement or bouncing during subsequent feeding or riveting processes, thus ensuring the accuracy of the riveting position.

[0024] 3. The automatic terminal assembly machine provided by this utility model includes a spring feeding mechanism and a bimetallic pre-pressing mechanism. Utilizing the elastic deformation characteristics of the bimetallic strip, the pre-pressing mechanism temporarily deforms it to create space for the spring insertion. Then, the pressure is released to allow it to spring back, and the insert portion of the bimetallic strip automatically inserts into the spring's insertion hole. This design avoids complex mechanical forced engagement, features a clever structure and gentle operation, effectively protects parts from damage, and improves the success rate and consistency of insertion.

[0025] 4. The automatic assembly machine for terminal components provided by this utility model includes a spring sheet feeding mechanism comprising a spring sheet material strip reel, a first material strip conveying assembly, and a first slicing mechanism. The first material strip driving claw is rotatably mounted on an eighth push plate via a first spring and has a first claw-shaped portion that cooperates with a first connecting piece. When the first material strip driving claw moves in one direction with the eighth push plate, under the elastic force of the first spring, the first claw-shaped portion of the first material strip driving claw extends into the first through hole of the first connecting piece, driving the spring sheet material strip to move synchronously. When the first material strip driving claw moves in the opposite direction with the eighth push plate, the first material strip driving claw moves relative to the spring sheet material strip. The design of the first material strip driving claw and the first slicing mechanism realizes the intermittent and precise feeding of the material strip and the precise cutting and separation of individual spring sheets.

[0026] 5. The terminal assembly automatic assembly machine provided by this utility model includes a terminal screw base assembly device comprising a base feeding mechanism, a screw driving mechanism, a flipping mechanism, a terminal base assembly mechanism and a third material transfer mechanism arranged in sequence. After the adjusting screw is assembled, the base is flipped 180° by the flipping mechanism, thereby facilitating the installation of subsequent parts.

[0027] 6. The automatic terminal assembly machine provided by this utility model has a second turntable with multiple slider push rod assemblies corresponding to the second fixture. Each slider push rod assembly includes a second slide rail, a slider, and a terminal push rod. The second slide rail is arranged radially along the second turntable. The slider is slidably mounted on the second slide rail, and its top is provided with a first protrusion and a second protrusion arranged opposite to each other. When the second turntable drives the second fixture to rotate to the corresponding assembly position, the drive block of the eighteenth cylinder assembly is inserted between the first protrusion and the second protrusion, thereby driving the slider to move and smoothly push the first terminal assembly into the base. It has the advantage of simple structure.

[0028] 7. The automatic terminal assembly machine provided by this utility model has a screw height detection mechanism that can detect online whether screws are missing or have an unqualified screw depth, thus realizing process quality control. In addition, the matching defective product discharge mechanism can automatically remove the detected defective products in a timely manner, preventing them from flowing into subsequent processes or mixing with qualified products, thus ensuring the quality purity of the final product batch. It is a key link in realizing fully automated high-quality production. Attached Figure Description

It has a first claw-shaped portion 81 that cooperates with the first connecting piece 73. The first material strip driving claw 77 has a vertical driving surface and an inclined surface on its two sides.

When the first material strip driving claw 77 moves in the opposite direction with the eighth push plate 79, the inclined surface of the first material strip driving claw 77 slides in contact with the first connecting piece 73, moving relative to the spring strip material strip 72.

The spring assembly bending device 32 inserts and fixes the other end of the bimetallic strip 3 to the spring, so that the spring 6, the bimetallic strip 3, and the first terminal 4 form a first terminal assembly 7. After bending the bimetallic strip 3 at a certain angle, the first terminal assembly 7 is assembled with the base 1. By integrating the two core processes of bimetallic terminal riveting and spring assembly bending into one machine, the entire process of production from parts to sub-assemblies is automated. The process of riveting first, then inserting, and then bending can effectively ensure the accuracy of the insertion of the bimetallic strip and the spring and the stability of the bending angle, thereby ensuring the consistency of the quality and performance of the final assembled product.
