Description

Technical Field

[0001] The present invention relates to the field of automatic assembly of relays, and in particular to a double-head self-adaptive flexible pressure relay shrapnel device and an assembly machine thereof. Background Art

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in an electrical output circuit when the change in the input quantity reaches a specified level. It interacts between a control system, also known as the input circuit, and a controlled system, also known as the output circuit. Commonly used in automated control circuits, it acts as an "automatic switch" that uses a small current to control a large one. It performs functions such as automatic regulation, safety protection, and circuit switching within circuits.

[0003] The structure of the relay includes components such as the relay housing, relay coil, relay frame, and relay hook. The relay housing is a box-shaped structure with an open top and an installation cavity inside. The relay coil is installed on the relay hook to form an assembly and is inserted into the installation cavity. The bottom of the relay hook is the bottom plate of the frame structure, and the upper part of the bottom plate is provided with an upward extending spring sheet with contacts on the spring sheet. During the assembly process, a sheet-like spring sheet needs to be inserted into the relay hook. Since the spring sheet is a flexible sheet structure, it is easy to bend under pressure during insertion into the relay hook, and the flatness of the insertion cannot be accurately guaranteed, and it is very easy for the heights on both sides to be different. Summary of the Invention

In the natural state, the elastic force of the adaptive spring makes the two groups of pressing assemblies move away from each other; when the lifting slide drives the two groups of pressing assemblies to descend, the pressing assemblies are pushed closer to each other by the guide arc surface of the inner wall of the sliding cavity, and the relay spring of the relay assembly below is pressed into the relay hook.

[0006] Preferably, the relay assembly includes a relay hook and a relay spring, wherein the relay hook is horizontally arranged in a jig and clamped and fixed by the jig, and a spring groove is provided on the relay hook; the relay spring is a sheet-like structure, the relay spring is inserted into the spring groove, and after being pressed by two sets of pressing components, the relay spring is pressed into the spring groove.

[0011] An assembly machine for a double-head adaptive flexible pressure relay spring device.

[0012] The beneficial effects of the present invention are: In response to the defects and shortcomings of the existing technology, the present invention independently developed and designed a double-headed adaptive flexible pressure relay spring device and its assembly machine, which can simultaneously press down from both sides of the relay spring, and simultaneously press horizontally while pressing, to ensure the pressing flatness and force uniformity, effectively improve the flatness of the relay spring insertion, and reduce deformation during the pressing process.

[0013] The present invention aims to provide a device for the automatic assembly of relays, which enables the automatic insertion of relay springs into spring slots on relay hooks. The device is particularly advantageous in that it comprises two sets of pressing assemblies, each of which moves downward from the left and right sides of the relay spring, achieving double-ended pressing on both sides. Compared to conventional single-sided pressing, this dual-ended, synchronous pressing method effectively ensures the height consistency of the left and right sides of the relay spring during the pressing process. It also effectively prevents spring deformation caused by uneven force on the left and right sides of the relay spring during the pressing process, effectively ensuring the success of the spring pressing. Furthermore, the pressing assembly of the present invention uses a pressing slide as an execution structure, and the pressing slide is movable in the horizontal direction. The pressing slides of the two groups of pressing assemblies are respectively slidably embedded in the guide rails provided at the bottom of the lifting slide through the transverse slide grooves opened on the top thereof. The two pressing slides are connected by a horizontally arranged adaptive spring. In the natural state, the elastic force of the adaptive spring pushes the two pressing slides away from each other outward; in addition, a roller groove is also provided in the pressing slide, and a support shaft is horizontally inserted in the roller groove. A roller is rotatably sleeved on the support shaft, and the lower part and side of the roller extend to the lower side and outer side of the pressing slide respectively. In addition, the sliding cavity vertically arranged in the press-fit support of the present invention includes an upper section and a lower section, and the width of the upper section is greater than that of the lower section, and the upper and lower sections are connected by a guiding arc surface; when the two press-fit slides slide downward in the upper section of the sliding cavity together with the lifting slide and approach the relay spring below, the elastic force of the adaptive spring pushes the two press-fit slides toward the outside, so that the rollers of the two press-fit slides approach the inner wall of the sliding cavity, and are limited by the roller guide, and the rollers roll on the inner wall of the sliding cavity to reduce the friction during the guide limitation process; when the rollers move to the guide arc surface, the reaction force of the guide arc surface against the rollers pushes the two rollers and the press-fit slide to overcome the elastic force of the adaptive spring, and gradually brings the two press-fit slides closer to the middle. At this time, the pressing piece under the press-fit slide sticks to the lower part of the relay spring from above and extends to the left and right sides. On the extended boss piece, as the pressing slide continues to descend, the pressing slide drives the pressing piece to slide gradually inward on the top surface of the boss piece. Compared with the traditional vertical direct pressing method, this method gradually moves horizontally on the boss during the vertical downward pressing process, and while pressing down the relay spring piece, the contact points between the pressing piece and the boss slide gradually from the left and right outside to the inside respectively, transforming the traditional line contact into point contact pressing, which can reduce the pressing pressure of the relay spring piece and effectively ensure the flatness of the relay spring piece during the pressing process, and ensure the high consistency of the relay spring piece after insertion. By driving the lifting slide with a single power, the two pressing slides are synchronously pressed on the relay spring piece from both sides, and the direction of force is converted by the guide arc surface, while saving the pressing power, effectively ensuring the movement synchronization of the pressing slides on both sides.

Example 2

[0033] As another embodiment, the present invention discloses an assembly machine for a double-headed adaptive flexible pressure relay spring device.

[0034] Furthermore, the present invention designs a double-headed adaptive flexible pressure relay spring device and its assembly machine that can press down synchronously from both sides of the relay spring, and simultaneously press horizontally while pressing down, so as to ensure the flatness of the pressing and the uniformity of the force, effectively improve the flatness of the relay spring insertion, and reduce the deformation during the pressing process. The present invention aims to provide a device used in the field of automatic assembly of relays, which can realize the automatic insertion of the relay spring into the spring slot of the relay hook. The special feature is that the present invention includes two groups of pressing components. The two groups of pressing components move downward from the left and right sides of the relay spring respectively to realize double-head pressing on the left and right sides.
