Description

Technical Field

[0001] This invention relates to the field of relay testing technology, and more specifically to a working method of a testing device applied to relay components. Background Technology

[0002] A relay, a widely used electronic control device in electrical control systems, serves as both a control system and a controlled system. It primarily acts as an "automatic switch," controlling larger currents within the entire electrical control system through electromagnetic induction generated by its own small current. Relays play a crucial role in electrical control systems, providing functions such as safety protection, circuit switching, and automatic adjustment.

[0003] Existing technology, such as Chinese Patent Application No. 202323255256.0, published on September 6, 2024, discloses an automatic testing device for relays, which includes a frame, a conveying device, a testing mechanism, and a feeding mechanism. The frame includes a worktable. The conveying device includes a conveying slide rail, a conveying slide plate, a conveying cylinder, and a conveying connecting plate. The testing mechanism includes a first testing mechanism, a second testing mechanism, and a third testing mechanism. The feeding mechanism includes a sliding assembly, a lifting assembly, a gripper assembly, and a collection hopper. Compared with existing technologies, this document, by setting up the testing mechanism, utilizes the first, second, and third probes to contact the electrodes of the relay and energize them, thereby achieving electrical performance testing of the relay and ensuring the production quality of the relay. Furthermore, by setting up the conveying device to transport the relay, the lifting assembly to lower and grasp the gripper assembly, and then the sliding assembly to complete the feeding and collection, it achieves full automation, high work efficiency, and low labor costs.

[0004] However, as described in the prior art of this document, the testing mechanism used to test relays is in direct contact with the relay. This results in rigid contact between the testing mechanism and the relay. Excessive contact can easily cause collision damage to the mechanism, while insufficient contact can easily lead to inaccurate relay testing. Summary of the Invention

[0005] This invention provides a method for operating a testing device applied to relay components, ensuring that the probe can make full contact with the relay while preventing rigid collisions between the probe and the relay.

[0006] To achieve the above objectives, the technical solution of the present invention is: a working method of a testing device applied to a relay assembly, comprising a testing frame, a conveyor belt on the testing frame, the conveyor belt being located on both sides of the center of the testing frame, a probe assembly for resistance testing of the connection terminals of a moving spring on the testing frame between the conveyor belts, a push rod assembly on the testing frame above the conveyor belt, a relay placement fixture on the conveyor belt, and a moving spring placed on the relay placement fixture; the push rod assembly moves downward and contacts the moving spring, and a connection terminal is provided at the bottom of the moving spring; the probe assembly moves upward and contacts the connection terminal of the moving spring; the positions of the push rod assembly, the probe assembly, and the connection terminal of the moving spring correspond; the probe assembly includes a probe driving component, a probe buffer component, and a probe; the probe driving component is disposed on the testing frame, and the probe is connected to the probe driving component through the probe buffer component; the probe driving component drives the probe to move upward and contact the connection terminal of the moving spring while compressing the probe buffer component;

[0007] The specific steps include:

[0008] (1) The conveyor belt transports the relay placement fixture to the top of the probe assembly, and the moving spring is located between the push rod assembly and the probe assembly.

[0009] (2) The push rod assembly moves downward and comes into contact with the moving spring.

[0010] (3) The probe driving component drives the probe to move upward and contact the connecting terminal of the moving spring.

[0011] (4) The probe driving component continues to drive the probe to move upward a certain distance.

[0012] (5) The resistance of the connection terminal of the moving spring is detected by probe.

[0013] The above method, by setting a probe assembly below the conveyor belt, ensures that when the relay placement fixture moves to the position of the testing frame during the conveying process, the push rod assembly moves downward and contacts the moving spring, while the probe moves upward and contacts the connecting terminal of the moving spring. This allows the moving spring to be clamped by the push rod assembly and the probe, preventing it from detaching. At the same time, by setting a probe buffer component, the probe can continue to move upward a certain distance after contacting the connecting terminal of the moving spring. This ensures that the probe can fully contact the connecting terminal of the moving spring while preventing rigid collisions between the probe and the connecting terminal of the moving spring.

[0014] Furthermore, the probe buffer component includes a probe buffer stage and a probe buffer spring. The probe buffer stage is disposed on the probe driving component, and a buffer hole is provided on the probe buffer stage. The probe is located in the buffer hole, and a probe buffer spring is provided between the top end of the probe and the top end of the buffer hole.

[0015] The above settings, through the setting of the probe buffer spring, enable the probe to have a buffering effect when it contacts the connecting terminal of the moving spring, thus preventing rigid contact between the probe and the connecting terminal of the moving spring.

[0016] Furthermore, a terminal contact plate is provided at the top of the probe, and the cross-sectional area of ​​the terminal contact plate is larger than the cross-sectional diameter of the probe.

[0017] The above settings, through the configuration of the terminal contact plate, allow for a larger contact area between the probe and the connecting terminal of the moving spring, thereby making the detection more accurate.

[0018] Furthermore, the probe driving component includes a probe mounting plate and a probe driving cylinder. The probe driving cylinder is mounted on the detection frame via the probe mounting plate, and a probe buffer stage is provided on the piston rod of the probe driving cylinder.

[0019] The above setup ensures that the probe can make contact with the connection terminal of the moving spring by driving the probe cylinder to move the probe upward.

[0020] Furthermore, a measuring groove is provided below the relay placement fixture, through which a probe passes and contacts the connection terminal of the moving spring.

[0021] The above settings, through the inclusion of a measuring slot, facilitate the testing of the connection terminals of the moving spring.

[0022] 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 mounted on the testing frame, and the push rod is connected to the drive shaft of the push rod servo motor through the push rod buffer component.

[0023] Step (2) specifically includes:

[0024] (21) The push rod servo motor drives the push rod to move downward and make contact with the moving spring.

[0025] (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.

[0026] The above configuration, by incorporating a push rod buffer component, provides a buffering effect when the push rod contacts the moving spring, thereby preventing a rigid connection between the push rod and the moving spring.

[0027] Furthermore, the push rod buffer component includes a push rod connecting plate, a push rod buffer spring, a push rod mounting base, and a push rod buffer rod. The push rod connecting plate is mounted on the drive 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 base. The push rod buffer rod is located inside 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, and the other end of the push rod buffer spring is connected to the push rod mounting base. A push rod is provided at the bottom end of the push rod mounting base.

[0028] The above setup, through the push rod buffer spring, allows the push rod buffer spring to be compressed when the push rod contacts the moving spring, thereby achieving a buffering effect. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 and Figure 6 As shown; a testing device for relay components includes a testing frame 1, on which a conveyor belt 12 is provided (in Figure 6 As shown in the diagram, the conveyor belt 12 is located on both sides of the center of the testing frame 1. A probe assembly 2 for resistance detection of the connection terminal 02 of the movable spring 01 is provided on the testing frame 1 between the conveyor belts 12. A push rod assembly 3 is provided on the testing frame 1 above the conveyor belt. A relay placement fixture 11 is provided on the conveyor belt, and the movable spring 01 is placed on the relay placement fixture 11. The push rod assembly 3 moves downward and contacts the movable spring 01. A connection terminal 02 is provided at the bottom of the movable spring 01. The probe assembly 2 moves upward and contacts the connection terminal 02 of the movable spring 01. The positions of the push rod assembly 3, the probe assembly 2, and the connection terminal 02 of the movable spring 01 correspond. In this embodiment, as... Figure 5 As shown, a proximity switch 14 is also provided on the detection frame 1 outside the conveyor belt 12. After the conveyor belt 12 transports the relay placement fixture 11 to the position of the detection frame 1, the proximity switch 14 is triggered and controls the conveyor belt 12 to stop transporting, so that the relay placement fixture 11 can stop at the position corresponding to the push rod assembly 3 and the probe assembly 2. The proximity switch 14 is an existing sensor control device, and its specific working method is existing technology, which will not be described in detail here.

[0039] like Figure 1 and Figure 3 As shown, the probe assembly 2 includes a probe driving component 21, a probe buffer component 22, and a probe 23. The probe driving component 21 is mounted on the detection frame 1. The probe 23 is connected to the probe driving component 21 through the probe buffer component 22. The probe driving component 21 drives the probe 23 to move upward and contact the connection terminal 02 of the moving spring 01 while compressing the probe buffer component 22.

[0040] like Figure 3 As shown, the probe buffer component 22 includes a probe buffer platform 221 and a probe buffer spring 222. The probe buffer platform 221 is disposed on the probe driving component 21, and a buffer hole 223 is provided on the probe buffer platform 221. The probe 23 is located in the buffer hole 223, and the probe buffer spring 222 is provided between the top end of the probe 23 and the top end of the buffer hole 223. The probe buffer spring 222 provides a buffering effect when the probe 23 contacts the connection terminal 02 of the moving spring 01, preventing rigid contact between the probe 23 and the connection terminal 02 of the moving spring 01.

[0041] like Figure 3 As shown, a terminal contact plate 231 is provided at the top of the probe 23, and the cross-sectional area of ​​the terminal contact plate 231 is larger than the cross-sectional diameter of the probe 23. By setting the terminal contact plate 231, a larger contact area is provided between the probe 23 and the connection terminal 02 of the moving spring 01, thereby making the detection more accurate.

[0042] like Figure 1 As shown, the probe driving component 21 includes a probe mounting plate 212 and a probe driving cylinder 211. The probe driving cylinder 211 is mounted on the detection frame 1 via the probe mounting plate 212, and a probe buffer platform 221 is provided on the piston rod of the probe driving cylinder 211. The probe driving cylinder 211 drives the probe 23 to move upward, thereby ensuring that the probe 23 can contact the connection terminal 02 of the moving spring 01.

[0043] like Figure 2 As shown, a measuring groove 111 is provided below the relay placement fixture 11, and the probe 23 passes through the measuring groove 111 to contact the connection terminal 02 of the moving spring 01. The measuring groove 111 facilitates the testing of the connection terminal 02 of the moving spring 01.

[0044] In this embodiment, as Figure 6 As shown, the conveyor belt 12 includes a first conveyor belt 121 and a second conveyor belt 122. The first conveyor belt 121 and the second conveyor belt 122 are respectively arranged on both sides of the detection frame 1, and a gap 13 is formed between the first conveyor belt 121 and the second conveyor belt 122. A probe assembly 2 is provided in the gap. The relay placement fixture is located on the first conveyor belt and the second conveyor belt. The measuring groove 111 is located above the gap 13. The probe 23 passes through the gap 13 and the measuring groove 111 and contacts the connection terminal 02 of the moving spring 01.

[0045] like Figure 1 and Figure 4 As shown, the push rod assembly 3 includes a push rod servo motor 31, a push rod buffer component 32, and a push rod 33. The push rod servo motor 31 is mounted on the detection frame 1, and the push rod 33 is connected to the drive shaft of the push rod servo motor 31 through the push rod buffer component 32. By providing the push rod buffer component 32, the push rod 33 provides a buffering effect when it contacts the moving spring 01, thereby preventing a rigid connection between the push rod 33 and the moving spring 01.

[0046] 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 base 323, and a push rod buffer rod 324. The push rod connecting plate 321 is mounted on the drive shaft of the push rod servo motor 31. The push rod buffer rod 324 is provided on the push rod connecting plate 321, and a push rod buffer hole 325 is provided on the push rod mounting base 323. The push rod buffer rod 324 is located inside the push rod buffer hole 325, and the push rod buffer spring 322 is sleeved on the push rod buffer rod 324. One end of the push rod buffer spring 322 is connected to the push rod connecting plate 321, and the other end of the push rod buffer spring 322 is connected to the push rod mounting base 323. A push rod 33 is provided at the bottom end of the push rod mounting base 323. Through the push rod buffer spring 322, when the push rod 33 contacts the moving spring 01, the push rod buffer spring 322 can be compressed, thereby playing a buffering role.

[0047] like Figure 7 As shown, a method for operating a detection device applied to relay components includes the following steps:

[0048] (1) The conveyor belt transports the relay placement fixture 11 to the top of the probe assembly 2, and the moving spring 01 is located between the push rod assembly 3 and the probe assembly 2.

[0049] (2) The push rod assembly 3 moves downward and comes into contact with the moving spring 01.

[0050] (21) The push rod servo motor 31 drives the push rod 33 to move downward and come into contact with the moving spring 01.

[0051] (22) The push rod servo motor 31 continues to drive the push rod 33 to move downward a certain distance to compress the push rod buffer component 32.

[0052] (3) The probe driving component 21 drives the probe 23 to move upward and contact the connecting terminal 02 of the moving spring 01.

[0053] (4) The probe driving component 21 continues to drive the probe 23 to move upward a certain distance.

[0054] (5) The resistance of the connection terminal 02 of the moving spring 01 is detected by probe 23.

[0055] The working principle of this invention is as follows: By setting a probe assembly 2 below the conveyor belt, when the relay placement fixture 11 moves to the position of the detection frame 1 during the conveying process, the push rod assembly 3 moves downward and contacts the moving spring 01, while the probe 23 moves upward and contacts the connection terminal 02 of the moving spring 01. This allows the moving spring 01 to be clamped by the push rod assembly 2 and the probe assembly 3, preventing the moving spring 01 from detaching. At the same time, by setting a probe buffer component 22, the probe 23 can continue to move upward a certain distance after contacting the connection terminal 02 of the moving spring 01. This ensures that the probe 23 can fully contact the connection terminal 02 of the moving spring 01, while preventing rigid collisions between the probe 23 and the connection terminal 02 of the moving spring 01. The probe buffer spring and the push rod buffer spring allow the push rod and the probe to fit tightly against the moving spring, thereby forming a circuit on the moving spring, which facilitates the detection of the resistance of the connection terminal of the moving spring.
