Description

Technical Field

[0001] The invention relates to the technical field of relay detection, and in particular to a working method of a detection device applied to a relay assembly. Background Art

[0002] Relay is an electronic control device widely used in electrical control systems. It has control systems and controlled systems. It is mainly an "automatic switch" that controls the larger current in the entire electrical control system through electromagnetic induction generated by the smaller current of the relay itself. Relay plays a very important role in electrical control systems, with functions such as safety protection, circuit conversion, and automatic adjustment.

[0003] Prior art, such as the patent document with Chinese patent application number 202323255256.0 and announcement date 2024.09.06, discloses an automatic detection device for relays, which includes a frame, a handling device, a testing mechanism, and a material unloading mechanism. The frame includes a work surface. The handling device includes a handling slide rail, a handling slide plate, a handling cylinder, and a handling connecting plate. The testing mechanism includes a first testing mechanism, a second testing mechanism, and a third testing mechanism. The material unloading mechanism includes a sliding assembly, a lifting assembly, a clamping claw group, and a collecting hopper. Compared with the prior art, the document sets the testing mechanism, uses the first probe, the second probe, and the third probe to contact the electrodes of the relay and energize, thereby realizing the electrical performance test of the relay and ensuring the production quality of the relay. And by setting the handling device to carry the relay, the clamping claw group is lowered and the relay is grabbed by the lifting assembly, and then the unloading and collection are completed by the sliding assembly, so as to achieve full automation, high work efficiency, and low labor cost.

[0004] However, as in the prior art of the document, the test mechanism used to detect the relay is in direct contact with the relay, which results in rigid contact between the test mechanism and the relay. If there is too much contact, it is easy to cause collision damage to the mechanism, and if there is not enough contact, it is easy to cause inaccurate detection of the relay. Summary of the invention

[0005] The present invention provides a working method of a detection device applied to a relay assembly, which ensures that a probe can fully contact the relay and prevents the problem of rigid collision between the probe and the relay. To achieve the above-mentioned purpose, the technical scheme of the present invention is: a working method of a detection device applied to a relay assembly, comprising a detection frame, a conveyor belt is provided at the center of the detection frame, the conveyor belt is located on both sides of the center of the detection frame, a probe assembly for performing resistance detection on the connecting terminal of the dynamic spring member is provided on the detection frame between the conveyor belts, a push rod assembly is provided on the detection frame above the conveyor belt, a relay placement jig is provided on the conveyor belt, and a dynamic spring member is placed on the relay placement jig; the push rod assembly moves downward and contacts the dynamic spring member, a connecting terminal is provided at the bottom of the dynamic spring member, the probe assembly moves upward and contacts the connecting terminal of the dynamic spring member; the push rod assembly corresponds to the position of the connecting terminal of the probe assembly and the dynamic spring member; the probe assembly comprises a probe driving component, a probe buffer component and a probe, the probe driving component is provided on the detection frame, the probe is connected to the probe driving component through the probe buffer component, and the probe driving component drives the probe to move upward and contact the connecting terminal of the dynamic spring member while compressing the probe buffer component; The specific steps include: (1) The conveyor belt conveys the relay placement jig to the top of the probe assembly, and the dynamic spring member is located between the push rod assembly and the probe assembly.

[0006] (2) The push rod assembly moves downward and contacts the dynamic spring member.

[0007] (3) The probe driving component drives the probe to move upward and contact the connecting terminal of the dynamic spring member.

[0008] (4) The probe driving component continues to drive the probe upward a certain distance.

[0009] (5) Use a probe to test the resistance of the connection terminals of the dynamic spring.

[0010] The above method arranges a probe assembly under the conveyor belt, so that when the relay placement jig is in the process of being conveyed, after the relay placement jig is moved to the position of the detection rack, the push rod assembly moves downward and contacts the dynamic spring member, and the probe moves upward to contact the connecting terminal of the dynamic spring member, so that the dynamic spring member is clamped by the push rod assembly and the probe to prevent the dynamic spring member from being separated. At the same time, by arranging a probe buffer component, the probe can continue to move upward a certain distance when it contacts the connecting terminal of the dynamic spring member, thus ensuring that the probe can fully contact the connecting terminal of the dynamic spring member and preventing the problem of rigid collision between the probe and the connecting terminal of the dynamic spring member.

[0011] Furthermore, the probe buffer component includes a probe buffer table and a probe buffer spring. The probe buffer table is arranged on the probe driving component. A buffer hole is arranged on the probe buffer table. The probe is located in the buffer hole. A probe buffer spring is arranged between the top of the probe and the top of the buffer hole.

[0012] The above arrangement, through the arrangement of the probe buffer spring, plays a buffering role when the probe contacts the connecting terminal of the dynamic spring member, thereby preventing rigid contact between the probe and the connecting terminal of the dynamic spring member.

[0013] Furthermore, a terminal contact plate is provided at the top end of the probe, and the cross-sectional area of ​​the terminal contact plate is larger than the cross-sectional diameter of the probe.

[0014] The above arrangement, through the arrangement of the terminal contact plate, enables a larger contact area between the probe and the connecting terminal of the dynamic spring member, thereby making the detection more accurate.

[0015] Furthermore, the probe driving component includes a probe mounting plate and a probe driving cylinder. The probe driving cylinder is arranged on the detection frame through the probe mounting plate, and a probe buffer table is arranged on the piston rod of the probe driving cylinder.

[0016] With the above arrangement, the probe is driven by the probe driving cylinder to move upward, thereby ensuring that the probe can come into contact with the connecting terminal of the dynamic spring member.

[0017] Furthermore, a measuring groove is provided below the relay placement jig, and the probe passes through the measuring groove and contacts the connecting terminal of the dynamic spring member.

[0018] The above arrangement facilitates the detection of the connection terminals of the dynamic spring member through the arrangement of the measuring slot.

[0019] Furthermore, the push rod assembly includes a push rod servo motor, a push rod buffer component and a push rod. The push rod servo motor is arranged on the detection frame, and the push rod is connected to the driving shaft of the push rod servo motor through the push rod buffer component.

[0020] Step (2) specifically includes: (21) The push rod servo motor drives the push rod to move downward and contact the dynamic spring member.

[0021] (22) The push rod servo motor continues to drive the push rod to move downward a certain distance to compress the push rod buffer component.

[0022] The above arrangement, by providing the push rod buffer component, enables the push rod to play a buffering role when contacting the dynamic spring component, thereby preventing a rigid connection between the push rod and the dynamic spring component.

[0023] Furthermore, the push rod buffer component includes a push rod connecting plate, a push rod buffer spring, a push rod mounting seat and a push rod buffer rod. The push rod connecting plate is arranged on the driving shaft of the push rod servo motor, a push rod buffer rod is provided on the push rod connecting plate, a push rod buffer hole is provided on the push rod mounting seat, the push rod buffer rod is located in the push rod buffer hole, a push rod buffer spring is sleeved on the push rod buffer rod, one end of the push rod buffer spring is connected to the push rod connecting plate, the other end of the push rod buffer spring is connected to the push rod mounting seat, and a push rod is provided at the bottom end of the push rod mounting seat.

[0024] The above arrangement, through the push rod buffer spring, enables the push rod buffer spring to be compressed when the push rod contacts the dynamic spring member, thereby playing a buffering role. BRIEF DESCRIPTION OF THE DRAWINGS

By providing the push rod buffer component 32, the push rod 33 plays a buffering role when contacting the dynamic spring component 01, thereby preventing the rigid connection between the push rod 33 and the dynamic spring component 01.

[0042] like Figure 4As shown, the push rod buffer component 32 includes a push rod connecting plate 321, a push rod buffer spring 322, a push rod mounting seat 323 and a push rod buffer rod 324.
