Description

Technical Field

[0001] The invention relates to the technical field of relay assembly, and in particular to a detection method for reducing the defective rate of relay components. Background Art

[0002] Relays are a commonly used device in power systems. Currently, relays are assembled manually. However, since relays are composed of many parts and the size of each part is not very large, it is easy to make assembly errors during assembly, the assembly speed is very slow, and the efficiency is very low.

[0003] Prior art, such as Chinese patent application number 201811294674.1 and publication date 2018.12.21, discloses a relay assembly device, including a first workbench, on which a transmission device is provided, and on which the first workbenches on both sides of the transmission device are respectively provided a shell feeding mechanism, an adjusting cam feeding mechanism, a push plate feeding mechanism, a paddle feeding mechanism, an adjusting button feeding mechanism, a compensation lever feeding mechanism, a manual and automatic button feeding mechanism, a compensation assembly feeding mechanism, a front cover feeding mechanism, and a spring and stop button feeding mechanism, wherein the spring and stop button feeding mechanism are simultaneously connected to a feeding mechanism. This document can be used for relay assembly.

[0004] For example, the assembly device of the document directly assembles the components of the relay. However, since each component of the relay is usually processed separately and each component cannot completely reach the standard size, a certain deviation is basically reserved, and the plate body of the movable spring is generally installed in the installation groove of the shell to achieve installation. In this way, if the size of the shell is too small and the movable spring is too large, it is easy to cause mismatch during assembly, making the current relay scrapped and wasting resources. Moreover, if the shell and the movable spring are precisely required to be matched, a large number of shells and movable springs cannot be used, thereby wasting costs. Summary of the invention

[0005] The present invention provides a detection method for reducing the defective rate of relay components. Through the method of the present invention, the height of the relay housing and the movable spring can be detected, so that it can be determined whether the sizes of the current relay housing and the movable spring match, and whether the next step of assembly can be determined, thereby reducing the defective rate during assembly, and at the same time, the housing and movable spring pieces that do not meet the requirements are recycled and reused, thereby reducing costs.

[0007] The specific steps include: (1) The shell feeding device conveys the shell to the shell height detection device.

[0008] (2) The shell height detection device measures the height of the shell and sends the current shell height data to the information processing center.

[0009] (3) The movable spring member feeding device transports the movable spring member to the movable spring member height detection device.

[0010] (4) The dynamic spring component height detection device measures the height of the dynamic spring component and sends the current dynamic spring component height data to the information processing center.

[0011] (6) The information processing center compares the current height data of the housing and the dynamic spring.

[0012] (7) If the current height data of the housing and the movable spring member are within the preset deviation value range, proceed to step (9).

[0013] (8) If the current height data of the housing and the movable spring are not within the preset deviation value range, proceed to step (10).

[0014] (9) The housing conveying mechanism and the movable spring conveying mechanism respectively convey the current housing and movable spring to the same relay placement fixture, and then enter step (1) to start conveying the next housing and movable spring.

[0015] (10) The shell conveying mechanism and the movable spring conveying mechanism convey the shell and the movable spring to the second conveyor belt respectively; the second conveyor belt conveys the movable spring and the shell to the storage device to be tested, and then enters step (1) to start conveying the next shell and movable spring.

[0016] In the above method, a shell conveying mechanism and a movable spring conveying mechanism are arranged on the first frame, so as to facilitate conveying the shell and the movable spring to the relay placement jig, so as to facilitate subsequent assembly, and by arranging a shell height detection device and a movable spring height detection device, and the shell height detection device and the movable spring height detection device are communicatively connected with the information processing center, the shell height detection device and the movable spring height detection device send the height data of the shell and the height data of the movable spring in the same relay placement jig to the information processing center, and the information processing center determines whether the difference between the height dimension of the shell and the height dimension of the movable spring is within a preset deviation value range, and then controls the shell conveying mechanism and the movable spring conveying mechanism to convey the shell and the movable spring to the relay placement jig or to the second conveyor belt respectively, so that, This enables the dimensional deviation value between the housing and the moving spring to be determined based on the height data of the detected housing and the moving spring to determine whether to proceed to the next step of assembly, so that the subsequent assembly can ensure that the size of the moving spring matches the size of the housing, thereby ensuring the efficiency of assembly and not easily increasing defective products. For the moving spring and the relay housing that only have deviations in height dimensions, it is easy to increase costs if they are directly discarded. For example, when the height of the mounting groove on the housing is slightly greater than the thickness of the moving spring, this situation does not affect the installation, so the installation can continue. If the height of the mounting groove is slightly lower than the thickness of the moving spring, it can also be installed. When the height of the mounting groove is greatly different from the thickness of the moving spring plate, it can be recycled through a conveyor belt, thereby saving more costs.
