Relay packaging equipment capable of protecting pins and improving film utilization rate

Abstract

The invention discloses relay packaging equipment capable of protecting pins and improving the film utilization rate. The relay packaging equipment capable of protecting the pins and improving the film utilization rate comprises a packaging box, a power mechanism and a control mechanism, wherein the power mechanism and the control mechanism are arranged on the rear side of the packaging box; and apackaging cavity is arranged in the packaging box. According to the relay packaging equipment capable of the protecting pins and improving the film utilization rate provided by the invention, beforefilm packaging, the pins are wrapped by hard plastic shells in advance, so that possible pin bending is prevented, and meanwhile, the use cost and the transportation cost of large-area use of the hardplastic shells are reduced; a cut film is driven by a pressing block to be overlapped with the rear section and then heated to be bonded again, so that leftover materials generated after film cuttingare greatly reduced; when a feeding film roller is used up, the plastic film on a receiving film roller can be directly reused; and meanwhile, automation of the processing process is achieved, so that the processing efficiency is greatly improved, the labor force is saved, and the relay packaging and transporting cost is reduced.

Description

technical field [0001] The invention relates to a relay packaging device that protects pins and improves film utilization, and mainly relates to the technical field of relay packaging. Background technique [0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit; [0003] Some current relays have some exposed pins, which will affect the fin...

AI Technical Summary

Problems solved by technology

[0003] Some current relays have some exposed pins, which will affect the final packaging paper of the relay. In order to realize the packaging of the relay, the relay needs to be installed in a sealed protective case, but this protective case will not only occupy the packaging The space in the box is high, and the cost is high. If the film is used for packaging, the pins will be bent during the film pulling process, and after correct packaging, the pins may puncture the film during transportation and storage, causing the pins to be exposed for a long time. Oxidation and performance degradation are caused by air; the traditional method of film packaging is generally manual operation, which is time-consuming, laborious, low in efficiency, and difficult to realize automation. In view of the above shortcomings, the present invention improves
