Description

Technical Field

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

[0002] A relay is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirement. It is usually used in automated control circuits. In order to ensure that the relay can work stably under various conditions, it is necessary to conduct corresponding tolerance tests on it, mainly including vibration tests during transportation and use, durability under rated load, and environmental adaptability tests of the relay under different temperature and humidity conditions.

[0003] In the prior art, a large number of relay detection and corresponding devices are also disclosed. For example, a Chinese patent with publication number CN113866629A discloses a comprehensive test bench for relay performance and durability, including a test bench, a test host, and a relay fixing tool electrically connected to the test host, a relay coil power supply, multiple types of loads, a load power supply and a display, wherein the multiple types of loads include electronic loads, resistive loads, bulb loads and inductive loads, and different loads among the multiple types of loads are installed in different layers of the bench.

[0004] When in use, the relay under test is fixed on the relay fixing fixture, and the test parameters and control timing are stored through the test host, which is used to issue instructions to control the progress of the test. The relay coil power supply is used to provide energy, and then different load conditions are simulated for the relay under test through multiple types of loads, and the test results are displayed on the display.

[0005] However, in the process of using the above-mentioned prior art to detect the relay, there are still the following shortcomings: 1. Since the relay may be in different operating environments such as humidity and high temperature during actual use, it is necessary to detect the tolerance of the relay to load operation in different environments. However, the above-mentioned prior art can only provide different load conditions through multiple types of loads, and cannot detect the tolerance of the relay to load in different environments, thereby affecting the detection effect and reliability.

[0006] 2. Furthermore, the above-mentioned prior art cannot realize continuous batch detection of relays, so it is necessary to frequently install and disassemble the relays, which is cumbersome and affects the detection efficiency.

[0007] 3. In addition, the relay may be subjected to vibration during transportation and use, and the above-mentioned prior art cannot realize vibration detection during the relay load process, which further affects the detection effect, resulting in the relay after the detection being subjected to vibration during subsequent transportation and use, which may become unusable, thereby affecting the use effect.

[0015] As a preferred technical solution of the present invention, a gap is provided at the lower end of the reciprocating plate for the pressure plate to pass smoothly, and a baffle for sealing the gap is slidably installed on the top wall of the gap.

[0016] As a preferred technical solution of the present invention, the environment manufacturing mechanism also includes a support plate installed on the bracket, the support plate is located below the support plate, a power supply and an electronic load are installed on the upper end of the support plate, and a power supply socket is arranged inside the storage box, and the power supply socket has multiple sockets for adapting to different models of relays.

[0032] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0033] The embodiment of the present application discloses a relay tolerance detection device. It should be noted that the relay tolerance detection device of the present application is mainly used in the process of tolerance detection of relays. In terms of technical effect, it can simulate the environment of the relay 7 under test during its actual working process, so as to detect the tolerance of the relay 7 under test in different environments when under load; especially in the detection process, the circumferential movement of the relay 7 under test can be controlled, and continuous batch detection can be achieved, thereby improving the detection efficiency. During this period, the relay 7 under test can be pressed to limit the position, ensuring its stability during the detection process. Furthermore, the relay tolerance detection device of the present application can also control the relay 7 under test to vibrate up and down during its circumferential movement, thereby simulating the tolerance of the relay 7 under test to the vibration effect when under load, and further improving the detection effect of the relay 7 under test.

[0034] Example 1: Reference Figure 1 and Figure 2As shown, a relay tolerance detection device includes a support plate 1, a bracket 2 is installed at the bottom of which; a transfer plate 3, rotatably installed on the upper end of the support plate 1, and a plurality of annularly distributed storage boxes 4 for placing the relay 7 to be tested are installed on the upper end of the transfer plate 3; an arcuate cover shell 31, installed on the upper end of the support plate 1 and covering the transfer plate 3, a reinforcing plate 33 is installed between the arcuate cover shell 31 and the support plate 1, and is used to increase the stability of the arcuate cover shell 31, and either side of the arcuate cover shell 31 has a fan-shaped opening, which is used for installing and removing a loading station 32 for installing and removing the relay; an environment manufacturing mechanism 5, installed between the bracket 2 and the support plate 1, and is used to simulate the relay in different environments when working under load in different independent spaces, and the environment manufacturing mechanism 5 includes a sprayer 51 and an air pump 52 respectively connected to different independent spaces, and the independent spaces connected to the sprayer 51 and the air pump 52 are respectively a humidification station 53 and a heating station 54 simulating the relay in different environments.

[0035] Furthermore, in the present embodiment, in order to facilitate the continuous detection of the relay, the automatic rotation of the transfer plate 3 can be achieved in the present embodiment. Specifically, a hollow shaft 11 is rotatably installed in the middle of the support plate 1. The hollow shaft 11 is fixedly penetrated through the middle of the transfer plate 3, and a gear ring 12 is fixedly provided on the lower end of the hollow shaft 11. An intermittent motor 13 is provided at the lower end of the support plate 1 through a motor seat, and a gear 14 meshing with the gear ring 12 is fixedly provided on the output shaft of the intermittent motor 13.

[0036] During the specific operation, the intermittent motor 13 is first started, and the intermittent motor 13 drives the gear 14 to rotate. The gear 14 cooperates with the gear ring 12 to drive the hollow shaft 11 and the transfer plate 3 to rotate intermittently as a whole, and the transfer plate 3 rotates each time at an angle equal to the angle between two adjacent storage boxes 4; when the transfer plate 3 drives the storage box 4 to move to the loading station 32, the relay 7 to be tested is installed in the storage box 4, and then the intermittent motor 13 drives the transfer plate 3 to continue to rotate, and loads the relay 7 to be tested. During this period, the environment manufacturing mechanism 5 can simulate the relay 7 to be tested in actual use. The humidity can be increased by the humidifying station 53 to simulate the load operation of the relay 7 to be tested in a humid environment. The temperature can be increased by the heating station 54 to simulate the load operation of the relay 7 to be tested in a high temperature environment, thereby detecting the tolerance of the relay 7 to be tested in different environments under load. After the detection is completed, the transfer plate 3 drives the tested relay back to the loading station 32 to facilitate its removal and installation in the storage box 4. Repeating the above steps can realize continuous batch detection of the relays 7 to be tested, thereby improving the detection efficiency.

[0037] Reference Figure 1 and Figure 3As shown, in order to prevent air from entering the humidification station 53 and the heating station 54 and causing the humidity or temperature of the relay 7 to be tested to decrease in the simulated environment, in this embodiment, a reciprocating plate 34 is slidably penetrated on the arc-shaped cover shell 31 for dividing the interior of the arc-shaped cover shell 31 into a plurality of independent spaces, and a first top support ring 35 and a second top support ring 36 of the same axis are installed on the upper end of the transfer plate 3, and the reciprocating plate 34 is slidably clamped on the upper ends of the first top support ring 35 and the second top support ring 36, and the storage box 4 is located between the first top support ring 35 and the second top support ring 36.

[0038] Furthermore, in this embodiment, a plurality of protrusions 37 corresponding to the position of the storage box 4 are installed on the upper ends of the first top support ring 35 and the second top support ring 36. The protrusions 37 gradually tilt downward on the side close to the rotation direction of the transfer plate 3, and the height of the protrusions 37 is greater than the height of the storage box 4.

[0039] During specific operation, the humidification station 53 and the heating station 54 can be sealed by the reciprocating plate 34 to avoid damaging the humid environment and the high temperature environment and affecting the detection accuracy of the relay 7 to be tested; the transfer plate 3 drives the storage box 4 to move circumferentially while driving the first top support ring 35 and the second top support ring 36 to rotate synchronously. When the protrusions 37 on the upper ends of the first top support ring 35 and the second top support ring 36 contact the reciprocating plate 34, the reciprocating plate 34 can be propped up to facilitate the reciprocating plate 34 to move above the storage box 4, thereby avoiding the reciprocating plate 34 from interfering with the circumferential movement of the storage box 4; after the storage box 4 passes under the reciprocating plate 34, the protrusions 37 on the upper ends of the first top support ring 35 and the second top support ring 36 are disengaged from the reciprocating plate 34, so that the reciprocating plate 34 moves downward and resets under the action of gravity.

[0040] It should be noted that the transfer tray 3 only stops operating when it drives the storage box 4 and the relay to be tested 7 to move circumferentially to the loading station 32, the humidification station 53 and the heating station 54. Therefore, the transfer tray 3 will not stop operating when it drives the storage box 4 to pass under the reciprocating plate 34, so as to ensure that the storage box 4 passes through the reciprocating plate 34 quickly, and avoids the reciprocating plate 34 from moving up for a long time and destroying the simulated environment inside the humidification station 53 and the heating station 54; in addition, the transfer tray 3 stops operating after each up and down reciprocating movement of the reciprocating plate 34, so as to facilitate the sprayer 51 and the air pump 52 to humidify and heat the humidification station 53 and the heating station 54 respectively, so as to maintain the detection environment for the relay to be tested 7.

[0041] Reference Figure 4 and Figure 5As shown, in order to ensure the stability of the relay 7 to be tested during the detection process, in this embodiment, the relay 7 to be tested installed in the storage box 4 can be fixed in a corresponding limit position. Specifically, a pressure plate 41 is hingedly connected to the upper end of the storage box 4 near the side of the transfer plate 3 in the movement direction through a torsion spring, and a plurality of top blocks 42 are installed on the upper end of the transfer plate 3, which are respectively located on the side of the pressure plate 41 away from the storage box 4. The torsion spring always applies a driving force to the pressure plate 41, so that the pressure plate 41 rotates toward the side away from the storage box 4 in the initial state and abuts against the side wall of the top block 42. At this time, the pressure plate 41 remains in a vertical state (in Figure 4 As shown in the figure, an execution pressing plate 44 is installed on one side of the pressing plate 41 close to the storage box 4 through a plurality of supporting spring rods 43, and the supporting spring rods 43 always apply a pushing force to the execution pressing plate 44 away from the side of the pressing plate 41.

[0042] Furthermore, in the present embodiment, the pressing plate 41 is an arc-shaped structure, a side of the pressing plate 41 away from the storage box 4 is an arc-shaped convex surface, and a force-bearing elastic sheet 45 is disposed on the side of the pressing plate 41 away from the storage box 4 .

[0043] During specific operation, after the relay 7 to be tested is installed inside the storage box 4, the transfer plate 3 rotates and drives the storage box 4 to move circumferentially, and the storage box 4 drives the pressing plate 41 to move synchronously; when the storage box 4 moves to the inside of the arc-shaped cover 31, the pressing plate 41 contacts the top wall of the arc-shaped cover 31, so that the pressing plate 41 can be squeezed from a vertical state to a horizontal state (in the arc-shaped cover 31). Figure 5 As shown in the figure, at this time, the pressure plate 41 drives the execution plate 44 to press against the upper end of the relay 7 to be tested through the supporting spring rod 43, so that the relay 7 to be tested is automatically pressed and limited through the linkage effect among the transfer tray 3, the arc-shaped cover 31, the pressure plate 41 and the execution plate 44; when the transfer tray 3 drives the storage box 4 and the pressure plate 41 to move to the loading station 32, the pressure plate 41 moves out from the inside of the arc-shaped cover 31. At this time, the pressure plate 41 is reset to a vertical state under the action of the torsion spring and drives the execution plate 44 to release the limiting effect on the relay.

[0044] In addition, the force-bearing spring piece 45 itself has elasticity. When the pressure plate 41 is in a horizontal state, the force-bearing spring piece 45 at the upper end of the pressure plate 41 slides in contact with the top wall inside the arc-shaped cover shell 31. At this time, the force-bearing spring piece 45 is subjected to the pressure of the arc-shaped cover shell 31 and overcomes the elasticity of the torsion spring to squeeze the pressure plate 41 downward, thereby ensuring that the pressure plate 41 always remains in a horizontal state inside the arc-shaped cover shell 31, thereby ensuring that the execution plate 44 always presses and limits the relay 7 to be tested.

[0045] The cam 37 is used to push the top of the cam 37 up and down to push the top of the cam 37 down, so that the cam 37 can pass through the bottom of the cam 37 and the top of the cam 37 can push the top of the cam 37 up and down to push the top of the cam 37 down.

[0046] Reference Figure 2 , Figure 6 and Figure 7 As shown, in order to facilitate load detection of the relay 7 to be tested in different environments, a corresponding environment manufacturing mechanism 5 is also provided in this embodiment. Specifically, the environment manufacturing mechanism 5 also includes a supporting plate 55 installed on the bracket 2, and the supporting plate 55 is located below the supporting plate 1. A power supply 551 and an electronic load 552 are installed on the upper end of the supporting plate 55. A power supply socket 553 is arranged inside the storage box 4, and the power supply socket 553 has a plurality of sockets for adapting to different types of relays.

[0047] Furthermore, in this embodiment, a signal receiver 554 and a controller 555 are also installed on the upper end of the supporting plate 55, the sprayer 51, the air pump 52, the power supply 551, the electronic load 552 and the signal receiver 554 are electrically connected to the controller 555 respectively, and a display screen 556 electrically connected to the controller 555 is installed on the supporting plate 55 through a stabilizing frame; an input wire 557 and an output wire 558 are installed on the power socket 553, and an electric slip ring 559 is installed inside the hollow shaft 11, and the ends of the input wire 557 and the output wire 558 away from the power socket 553 are respectively connected to the power supply 551 and the electronic load 552 through the electric slip ring 559.

[0048] It should be noted that the controller 555, the electronic load 552 and the electric slip ring 559 used in this embodiment are all prior arts, wherein the controller 555 is a programmable PLC controller 555, which is used to receive and transmit signals and automatically control the operation of the power supply 551, the load, the sprayer 51 and the air pump 52; the electronic load 552 is a device that can simulate various load conditions (such as resistive, inductive, capacitive loads, etc.), and is used to load the output end of the relay 7 to be tested to test its switching ability and stability under actual working conditions; the electric slip ring 559 is used to connect the wires of the upper and lower parts of the hollow shaft 11, and can transmit the power supply 551 and the signal power supply 551 during unlimited continuous rotation. Therefore, when the hollow shaft 11 rotates, but the power supply 551 and the electronic load 552 cannot rotate, the electric slip ring 559 can ensure the electrical connection between the power socket 553 and the power supply 551 and the electronic load 552.

[0049] Furthermore, in this embodiment, a water tank 511 and an electric air heater 521 for supplying water to the sprayer 51 are also installed on the supporting plate 55, and the electric air heater 521 is connected to the air pump 52 through a conduit.

[0050] During the specific operation, the relay 7 to be tested is plugged into the power socket 553, and the power supply 551 and the electronic load 552 enable the relay 7 to simulate the load operation. At the same time, the controller 555 enables the sprayer 51 and the air pump 52 to be powered on and started. The sprayer 51 draws water from the water tank 511 and sprays it into the humidification station 53 for humidification. The air pump 52 draws heated air from the electric air heater 521 and sprays it into the heating station 54. Then the transfer plate 3 drives the storage box 4 and the relay 7 to move circumferentially to the humidification station. 53, in order to simulate the load operation of the relay 7 to be tested in a humid environment, when the transfer plate 3 drives the storage box 4 and the relay 7 to be tested to move to the heating station 54, it can simulate the load operation of the relay 7 to be tested in a high temperature environment, and then detect the tolerance of the relay 7 to be tested in different environments under load, so as to ensure the detection effect and reliability of the tolerance of the relay 7 to be tested; during the detection process, the signal receiver 554 sends the detection results to the display screen 556 in real time through the controller 555, so that the detection personnel can view them in real time.

[0051] Example 2: Reference Figure 8 and Fig. 9As shown, on the basis of Example 1, since the relay 7 to be tested is susceptible to vibration during transportation and use, based on this, in order to further improve the tolerance test of the relay 7 to be tested, in this embodiment, vibration detection of the relay 7 to be tested can also be performed. Specifically, support fins 61 are installed on both side walls in the length direction of the storage box 4, and a groove for accommodating the support fins 61 is opened on the transfer plate 3. A plurality of equidistantly distributed reset spring rods 62 are installed at the upper and lower ends of the support fins 61 and between the grooves. The reset spring rods 62 always apply a supporting elastic force to the support fins 61, and the upper and lower sides of the support fins 61 are subjected to equal supporting elastic forces. Therefore, the support fins 61 are located in the middle of the groove in the initial state.

[0052] Furthermore, in the present embodiment, a plurality of bosses 63 are equidistantly arranged at the lower end of the storage box 4 along the width direction, a plurality of positioning strips 64 staggered with the bosses 63 are installed at the upper end of the support plate 1 between the loading station 32 and the humidification station 53, and an arc pad 65 located below the humidification station 53, the heating station 54 and the loading station 32 is installed at the upper end of the support plate 1, and the arc pad 65 is abutted against the boss 63.

[0053] When the transfer plate 3 drives the storage box 4 to move circumferentially to between the loading station 32 and the humidifying station 53, the positioning strip 64 and the plurality of bosses 63 contact in sequence, and the positioning strip 64 drives the storage box 4 to move upward when it abuts against the boss 63. When the positioning strip 64 is located between the two bosses 63, the storage box 4 is driven to move downward and reset under the action of the reset spring rod 62. In this way, the positioning strip 64 and the boss 63 cooperate to control the storage box 4 to vibrate up and down, thereby simulating the tolerance of the relay 7 to be tested to the vibration effect under load, and further improving the detection effect of the relay 7 to be tested; when the transfer plate 3 drives the storage box 4 to move to the humidifying station 53, the heating station 54 and the loading station 32, the positioning strip 64 abuts against the upper end of the arc pad 65, so the storage box 4 will not vibrate, ensuring its stability during movement.

[0054] In addition, the present invention also provides a relay tolerance detection method, comprising the following steps: S1: Relay installation: First start the intermittent motor 13, the intermittent motor 13 drives the gear 14 to rotate, the gear 14 cooperates with the gear ring 12 to drive the hollow shaft 11 and the transfer plate 3 to rotate intermittently as a whole, when the transfer plate 3 drives the storage box 4 to move to the loading station 32, the relay 7 to be tested is plugged into the power socket 553 in the storage box 4, and the power supply 551 and the electronic load 552 can make the relay 7 to be tested simulate load operation.

[0055] S2: Relay transportation: The intermittent motor 13 drives the transfer plate 3 to continue to rotate, so that the transfer plate 3 drives the storage box 4 and the relay to be tested 7 to move circumferentially and move from the loading station 32 to the humidification station 53 and the heating station 54 in sequence for tolerance testing; when the transfer plate 3 drives the storage box 4 to move to the inside of the arc-shaped cover shell 31, the pressure plate 41 contacts the top wall of the arc-shaped cover shell 31 and is squeezed to a horizontal state. At this time, the pressure plate 41 drives the execution plate 44 to press against the upper end of the relay to be tested 7 through the supporting spring rod 43, so as to automatically press the relay to be tested 7 to limit the position, thereby ensuring the stability of the relay to be tested 7 during the detection process.

[0056] S3: Adjust the environment: The controller 555 is used to connect the power to the sprayer 51 and the air pump 52 to start. The sprayer 51 draws water from the water tank 511 and sprays it into the humidification station 53 for humidification. The air pump 52 draws heated air from the air electric heater 521 and sprays it into the heating station 54. Then, the transfer plate 3 drives the storage box 4 and the relay to be tested 7 to move circumferentially into the humidification station 53, so as to simulate the load operation of the relay to be tested 7 in a humid environment. When the transfer plate 3 drives the storage box 4 and the relay to be tested 7 to move into the heating station 54, it can simulate the load operation of the relay to be tested 7 in a high temperature environment, thereby detecting the tolerance of the relay to be tested 7 in different environments under load. During the detection process, the signal receiver 554 sends the detection results to the display screen 556 in real time through the controller 555, so that the detection personnel can view them in real time.

[0057] S4: Detection completed: After the detection of the relay 7 to be tested is completed, the transfer tray 3 drives the relay that has completed the detection back to the loading station 32, and the pressure plate 41 is moved out from the inside of the arc-shaped cover 31. At this time, the pressure plate 41 is reset to a vertical state under the action of the torsion spring and drives the execution plate 44 to release the limiting effect on the relay, so as to remove it and install it in the storage box 4 to the relay 7 to be tested.

[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0059] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
