Description

Technical Field

[0001] This invention relates to the field of electrical components for high and low voltage engineering, and particularly to equipment and methods for testing the seismic performance of electromagnetic relays in high and low voltage engineering. Background Technology

[0002] High and low voltage engineering requires the use of a large number of electrical components. Electromagnetic relays are one type of electrical component in high and low voltage engineering. Electromagnetic relays are subject to vibration during production and transportation. In order to ensure the use of electromagnetic relays, it is necessary to conduct vibration resistance testing.

[0003] Currently, seismic performance testing involves manually placing an electromagnetic relay into the seismic performance testing equipment for testing and processing. This method cannot perform continuous testing, has low testing efficiency, and cannot separate materials for processing.

[0004] Based on this, the present invention provides a device and method for testing the seismic performance of electromagnetic relays in high and low voltage engineering, so as to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the current problem that seismic performance testing involves manually placing the electromagnetic relay into the testing equipment for processing, which is inefficient, cannot perform continuous testing, and cannot process relays separately, this invention provides a seismic performance testing device and method for electromagnetic relays in high and low voltage engineering projects.

[0006] This invention proposes a device for testing the seismic performance of electromagnetic relays in high and low voltage engineering, including a frame, wherein a servo drive component is connected to the frame;

[0007] The outer wall of the servo drive assembly is provided with movable clamps at equal intervals for mounting electromagnetic relays;

[0008] The movable fixture includes a blocking component, a jitter support component, and a clamping component. The jitter support component is connected to the servo drive component, and the jitter support component is connected to the blocking component and the clamping component.

[0009] The frame is provided with a feeding component, a feeding unlocking component, a vibration driving component, a detection component, a good product discharge component, a discharging unlocking component, and a defective product discharge component in sequence from one end to the other. The distance between the feeding component and the vibration driving component, the distance between the vibration driving component and the detection component, the distance between the detection component and the good product discharge component, and the distance between the good product discharge component and the defective product discharge component are the same. The distance between the feeding component and the vibration driving component is the same as the distance that the servo driving component moves in a single movement.

[0010] Furthermore, the servo drive assembly includes a first drive motor, a synchronous pulley, a synchronous belt, and a rotating roller. The first drive motor is mounted on the outer wall of the frame, and the rotating roller is rotatably mounted on the inner wall of the frame via bearings at equal intervals. The rotating roller is symmetrically fixed with a synchronous pulley, and the synchronous pulley is rotatably connected to the synchronous belt.

[0011] Furthermore, the jitter support assembly includes a fourth support frame, a cam, a second spring, and a sliding plate. The fourth support frame is installed at equal intervals on the outer wall of the timing belt. The second spring is symmetrically fixed at the top of the fourth support frame. The top of the fourth support frame slides and is limited to the sliding plate through a straight sliding hole. The cam is fixed at the bottom of the sliding plate.

[0012] Furthermore, the clamping assembly includes a convex slot, a second transverse hole, and a support base. The top of the second spring and the sliding straight plate are both fixedly connected to the bottom of the support base. The rear side wall of the support base has a convex slot, and the front end of the convex slot has a second transverse hole.

[0013] Furthermore, the sealing assembly includes a connecting block, a straight rod, a first spring, and an inclined plate. The first spring is fixed to the bottom of the fourth support frame, the connecting block is fixed to the bottom of the first spring, the straight rod is fixed to the top of the connecting block, and the inclined plate is fixedly connected to the top of the straight rod after passing through the fourth support frame. The inclined plate is slidably connected to the rear end of the support seat. When the convex slot moves from the bottom to the top, the top of the inclined plate is always higher than the bottom of the convex slot.

[0014] Furthermore, the feeding and unlocking assembly includes a first pressure plate and a second support frame. The second support frame is installed at the rear top of the frame and is located at the right end of the movable clamp. The first pressure plate is fixed to the top of the second support frame. After the uppermost end of the inclined plate contacts the first pressure plate, the first pressure plate pushes the inclined plate to the lowermost end, and the top of the first pressure plate is lower than the bottom of the convex slot.

[0015] Furthermore, the feeding assembly includes a first support frame, a U-shaped guide trough, a first linear drive assembly, a discharge hole, and a first transverse hole. The first support frame is installed on the rear top of the frame, and the top of the first support frame is fixed with a U-shaped guide trough. The U-shaped guide trough is connected to the electromagnetic relay conveyor line. The front and rear side walls of the right end of the U-shaped guide trough are respectively provided with a discharge hole and a first transverse hole, and the bottom of the discharge hole is flush with the bottom of the convex slot. The first linear drive assembly is fixedly connected to the rear side of the first transverse hole of the U-shaped guide trough.

[0016] Furthermore, the vibration drive assembly includes a crossbar, a drive rod, a third support frame, and a second drive motor. The third support frame is installed between the inner walls of the frame. The second drive motor is fixed to the top of the third support frame. Crossbars are fixed at equal intervals at the output end of the second drive motor. A drive rod that cooperates with a cam is fixed to the outer end of the crossbar.

[0017] Furthermore, the positive product discharge assembly and the negative product discharge assembly have the same structure.

[0018] To better achieve the objectives of this invention, this invention also provides a testing method for electromagnetic relay seismic performance testing equipment in high and low voltage engineering, comprising the following steps:

[0019] Step 1: The electromagnetic relay conveyor line transports the electromagnetic relays to the U-shaped guide trough of the feeding component, moves them to the discharge hole, and the servo drive component drives the movable clamp to move to the discharge hole. The first pressure plate moves the inclined plate to the bottom and opens the movable clamp. The first linear drive component pushes the movable clamp inside to realize the automatic feeding of electromagnetic relays.

[0020] Step 2: The servo drive assembly then drives the movable fixture to separate from the first pressure plate. The straight rod of the sealing assembly drives the connecting block to move upward. The first spring drives the straight rod to move upward. The straight rod drives the inclined plate to move upward. The inclined plate and the support seat cooperate to keep the electromagnetic relay in the movable fixture. During vibration and detection, the electromagnetic relay is stably limited in the movable fixture.

[0021] Step 3: The servo drive assembly drives the movable fixture to move above the vibration drive assembly. The second drive motor drives the crossbar to rotate, and the crossbar drives the drive rod to rotate. The drive rod intermittently pushes the cam to move upward. The cam drives the electromagnetic relay in the convex slot to move upward through the sliding straight plate. After the drive rod separates from the cam, the second spring drives the electromagnetic relay in the convex slot to move downward, realizing the vibration simulation processing of the electromagnetic relay in the convex slot.

[0022] Step 4: The servo drive component then drives the movable fixture to below the detection component, and the detection component contacts the electromagnetic relay wire connection post to realize the detection and processing of the electromagnetic relay;

[0023] Step 5: After detection, the servo drive component drives the movable fixture again. After the movable fixture contacts the unloading unlocking component, the movable fixture is opened.

[0024] Step Six: Activate the positive product discharge component or the negative product discharge component according to the detection structure of the detection component. The positive product discharge component will discharge the positive products, and the negative product discharge component will discharge the negative products, thus realizing the material discharge.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The feeding unlocking component of this invention makes it easy to open the movable clamp by contacting the sealing component of the movable clamp, which facilitates automatic feeding by the feeding component. At the same time, after the feeding unlocking component separates from the sealing component of the movable clamp, the movable clamp fixes and limits the electromagnetic relay, which facilitates the stable installation of the electromagnetic relay in the movable clamp.

[0027] 2. After the vibration drive component of the present invention comes into contact with the shaking support component of the movable fixture, the vibration drive component simulates the vibration of the support base, which facilitates the vibration simulation processing of the electromagnetic relay inside the support base.

[0028] 2. The vibration simulation processing detection component of this invention detects the electromagnetic relay. After detection, the material unloading unlocking component and the sealing component of the movable clamp come into contact to facilitate the opening of the movable clamp, which facilitates the discharge of good products by the defective product discharge component and the good product discharge component, or facilitates the discharge of defective products by the defective product discharge component. This facilitates continuous detection, which has low detection efficiency, and at the same time, facilitates material sorting. Attached Figure Description

The distance between the feeding component 6 and the vibration drive component 8 is the same as the distance of a single movement of the servo drive component.

[0052] When the movable clamp 9 is loaded, the loading unlocking component 7 pushes the sealing component downward to open the movable clamp 9, and the loading component 6 pushes the electromagnetic relay into the movable clamp 9; the vibration drive component 8 drives the electromagnetic relay to vibrate, and the detection component 10 detects the electromagnetic relay after vibration. When unloading, the unloading unlocking component 12 pushes the sealing component downward to open the movable clamp 9, and the good product discharge component 11 or the defective product discharge component 13 discharges the corresponding product according to the structure detected by the detection component 10.

[0055] The contact between the feeding unlocking component 7 and the sealing component of the movable clamp 9 facilitates the opening of the movable clamp 9, enabling the feeding component 6 to automatically feed materials.

The guide trough 113 is installed at the top of the rear end of the frame 1.

[0065] After the detection component 10 detects the material, the unloading and unlocking component 12 contacts the sealing component of the movable clamp 9 to facilitate the opening of the movable clamp 9, so that the defective product discharge component 13 and the positive product discharge component 11 can discharge the positive product, or the defective product discharge component 13 can discharge the defective product, which facilitates continuous detection. The detection efficiency is low, but at the same time, it is convenient for material sorting.

[0066] To better achieve the objectives of this invention, this invention also provides a testing method for electromagnetic relay seismic performance testing equipment in high and low voltage engineering, comprising the following steps:

[0067] Step 1: The electromagnetic relay conveyor line transports the electromagnetic relay to the U-shaped guide trough 62 of the feeding component 6, moves it to the discharge hole 64, and the servo drive component drives the movable clamp 9 to move to the discharge hole 64. The first pressure plate 71 moves the inclined plate 96 to the bottom and opens the movable clamp 9. The first linear drive component 63 pushes the movable clamp 9 to realize the automatic feeding of the electromagnetic relay. After the feeding unlock component 7 separates from the sealing component of the movable clamp 9, the movable clamp fixes the electromagnetic relay in a limited position, so that the electromagnetic relay can be stably installed in the movable clamp 9.

[0068] Step 2: The servo drive assembly then drives the movable clamp 9 to separate from the first pressure plate 71. The straight rod 94 of the sealing assembly drives the connecting block 93 to move upward. The first spring 95 drives the straight rod 94 to move upward. The straight rod 94 drives the inclined plate 96 to move upward. The inclined plate 96 and the support seat 99 cooperate to keep the electromagnetic relay in the movable clamp 9. During vibration and detection, the electromagnetic relay is stably limited in the movable clamp 9.

[0069] Step 3: The servo drive assembly drives the movable fixture 9 to move above the vibration drive assembly 8. The second drive motor 84 drives the crossbar 81 to rotate, and the crossbar 81 drives the drive rod 82 to rotate. The drive rod 82 intermittently pushes the cam 92 to move upward. The cam 92 drives the electromagnetic relay in the convex slot 97 to move upward through the sliding plate 911. After the drive rod 82 separates from the cam 92, the second spring 910 drives the electromagnetic relay in the convex slot 97 to move downward, realizing the vibration simulation processing of the electromagnetic relay in the convex slot 97.

[0070] Step 4: The servo drive assembly drives the movable fixture 9 to below the detection assembly 10. The second linear drive assembly 105 drives the mounting plate 103 to move downward. The mounting plate 103 drives the ohmmeter 102 to move downward. The ohmmeter 102 drives the probe 101 to move downward until it contacts the electromagnetic relay wire connection post, thereby realizing the detection and processing of the electromagnetic relay.

[0071] Step 5: After detection, the servo drive component drives the movable clamp 9 again. After the movable clamp 9 contacts the second pressure plate 121 of the unloading unlocking component 12, it moves the inclined plate 96 to the bottom and opens the movable clamp 9. The movable clamp 9 is then opened.

[0072] Step 6: Activate the positive product discharge component 11 or the negative product discharge component 13 according to the detection structure of the detection component 10. The positive product discharge component 11 discharges the positive products and the negative product discharge component 13 discharges the negative products. This facilitates continuous detection, reduces detection efficiency, and facilitates material sorting.

8. A testing method for the electromagnetic relay seismic performance testing equipment in high and low voltage engineering as described in claim 7. Its features are, Includes the following steps: Step 1: The electromagnetic relay conveyor line transports the electromagnetic relay to the U-shaped guide trough (62) of the feeding component (6), moves it to the discharge hole (64), the servo drive component drives the movable clamp (9) to move to the discharge hole (64), the first pressure plate (71) moves the inclined plate (96) to the bottom and opens the movable clamp (9), the first linear drive component (63) pushes the movable clamp (9) inside to realize the automatic feeding of electromagnetic relays; Step 2: The servo drive assembly drives the movable clamp (9) to separate from the first pressure plate (71). The straight rod (94) of the sealing assembly drives the connecting block (93) to move upward. The first spring (95) drives the straight rod (94) to move upward. The straight rod (94) drives the inclined plate (96) to move upward. The inclined plate (96) and the support base (99) cooperate to keep the electromagnetic relay in the movable clamp (9). During vibration and detection, the electromagnetic relay is stably limited in the movable clamp (9). Step 3: The servo drive assembly drives the movable fixture (9) to move above the vibration drive assembly (8). The second drive motor (84) drives the crossbar (81) to rotate. The crossbar (81) drives the drive rod (82) to rotate. The drive rod (82) intermittently pushes the cam (92) to move upward. The cam (92) drives the electromagnetic relay in the convex slot (97) to move upward through the sliding straight plate (911). After the drive rod (82) separates from the cam (92), the second spring (910) drives the electromagnetic relay in the convex slot (97) to move downward, realizing the vibration simulation processing of the electromagnetic relay in the convex slot (97). Step 4: The servo drive component drives the movable fixture (9) to below the detection component (10), and the detection component (10) contacts the electromagnetic relay wire connection post to realize the detection processing of the electromagnetic relay; Step 5: After detection, the servo drive component drives the movable fixture (9) again. After the movable fixture (9) comes into contact with the unloading unlocking component (12), the movable fixture (9) is opened. Step 6: Activate the positive product discharge component (11) or the negative product discharge component (13) according to the detection structure of the detection component (10). The positive product discharge component (11) discharges the positive product and the negative product discharge component (13) discharges the negative product, thus realizing the material discharge.
