Description

Technical Field

[0001] This utility model belongs to the field of relay testing technology, and in particular relates to a rapid testing device for multi-module relays. Background Technology

[0002] Relay testing is a technical process that verifies the performance parameters and functional integrity of a relay through systematic testing. The core testing items include electrical characteristic testing, mechanical operation reliability verification, and environmental adaptability assessment. The testing methods cover quantitative means such as contact resistance measurement, operating voltage or current calibration, and insulation strength testing.

[0003] Currently, common benchtop relay testing equipment adopts a fixed testing platform structure. Its core components include a single testing station located at the top of the equipment, a testing mechanism fixed below the station, and a manual loading and unloading area adjacent to the station. In actual operation, after a relay is placed at the testing station to complete the testing process, the operator must manually remove the relay from the station and then place a new relay to be tested in the same position. This causes the testing equipment to be paused during each testing interval to wait for manual replacement, which severely restricts the overall testing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a rapid testing device for multi-module relays. A servo motor drives a turntable to rotate intermittently, causing multiple positioning slots to circulate through the testing mechanism and the automatic loading / unloading mechanism. The automatic loading / unloading mechanism synchronously loads relays to be tested into the empty positioning slots. As the turntable rotates, the relays reach the testing head, which performs the testing operation. An electric cylinder adjusts the height of the rotating motor and the testing head, and the rotating motor drives the rotating head to adjust its angle so that the testing endpoint of the testing head can properly contact the relay contacts, facilitating the testing. Simultaneously, the automatic loading / unloading mechanism removes the tested relays from the turntable, enabling the testing and loading / unloading processes to run concurrently. The equipment does not need to be paused for material replacement throughout the entire process, significantly improving the relay testing efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A rapid testing device for multi-module relays includes a base, a testing component, and a testing mechanism mounted on the base. The testing component includes a servo motor housed within the base, with the output end of the servo motor passing through the base and connected to a turntable. The turntable has multiple positioning slots, the centers of which are located on the same circumference. The positioning slots are used to place relays to be tested. The testing mechanism includes a mounting frame connected to the base, with an electric cylinder mounted on the mounting frame. The output end of the electric cylinder is connected to a rotary motor, and a testing head is mounted on the bottom of the rotary motor. The output end of the electric cylinder extends and retracts vertically, and the testing head is located above the turntable. An automatic loading and unloading mechanism is also provided on the base.

[0007] In this embodiment, a servo motor drives the turntable to rotate intermittently. The positioning slots facilitate the placement of relays to be tested. Multiple positioning slots circulate through the testing mechanism and the automatic loading and unloading mechanism. The automatic loading and unloading mechanism synchronously loads the relays to be tested into the empty positioning slots. The relays rotate with the turntable to the testing head, where the testing head performs the testing operation. An electric cylinder can adjust the height of the rotary motor and the testing head. The rotary motor drives the rotating head to adjust its angle so that the testing end of the testing head can make normal contact with the relay contacts, facilitating the testing of the relays. At the same time, the automatic loading and unloading mechanism discharges the tested relays from the turntable, realizing parallel testing and loading and unloading processes. The equipment does not need to be stopped to wait for material changes throughout the entire process, greatly improving the testing efficiency of relays.

[0008] In one embodiment, the automatic loading and unloading mechanism includes a bracket installed on one side of the top of the base, the bracket being connected to a feeding shell, a vibration motor being installed at one end of the feeding shell, and a discharge port located above the turntable being opened at the bottom of the other end, the position of the discharge port corresponding to the positioning groove; the automatic loading and unloading mechanism also includes a top material assembly and a pusher plate installed on the other side of the top of the base, the top material assembly having a top rod corresponding to the position of the positioning groove;

[0009] In this embodiment, the bracket provides stable support for the feeding shell, which is used to smoothly transport the relay. When the positioning groove and the discharge port are perpendicular, the relay passes through the discharge port and enters the positioning groove. When they are not perpendicular, the relay stays in the feeding shell. The top material assembly then uses the top rod to discharge the relay that has completed the test from the positioning groove and transfers it through the push plate.

[0010] In one embodiment, the automatic loading and unloading mechanism further includes a drive motor installed in the base, the output end of which passes through the base and is connected to the push plate.

[0011] In one embodiment, the top feeding assembly includes a top feeding motor installed in the base, the output end of the top feeding motor is connected to a cam, the top rod is disposed on the top of the cam, the top rod is also fitted with a spring, and the top of the top rod passes through the base and is located below the turntable;

[0012] In this embodiment, the top material motor installed in the base drives the cam to rotate. The cam acts on the top rod to discharge the relay in the positioning groove, and the spring sleeved on the top rod makes the top rod quickly return to its original position.

[0013] In one embodiment, the base is further provided with a slide rod and a slide sleeve fitted on the slide rod, the top and bottom of the slide rod are connected to the inner wall of the base, and the slide sleeve is connected to the top rod;

[0014] In this embodiment, the top rod is limited by a slide rod fixed in the base, so that it can move back and forth in the vertical direction more smoothly and prevent it from tilting or deviating during movement.

[0015] In one embodiment, an industrial camera is also provided on the mounting bracket, and the industrial camera is electrically connected to the electric cylinder and the rotary motor respectively;

[0016] In this embodiment, an industrial camera is used to photograph the relay. The captured image information is then used to control a rotary motor and an electric cylinder, enabling the detection tip of the detection head to quickly contact the relay contacts, thereby improving detection efficiency.

[0017] In one embodiment, a limiting cylinder is also installed on the mounting bracket. The limiting cylinder has an output end that extends in a vertical direction, and the output end of the limiting cylinder is connected to a friction plate.

[0018] In this embodiment, a limit cylinder is used to move the friction plate vertically. When the relay needs to be tested, the friction plate contacts the turntable, and the friction prevents it from rotating, so that it remains in a more stable state when it stops rotating. This improves the testing accuracy and avoids the detection head from affecting the relay testing effect if the turntable rotates unexpectedly.

[0019] In one embodiment, the bracket has an L-shaped structure, with one end connected to the top of the base and the other end located above the turntable and connected to the feeding shell.

[0020] In one embodiment, the feeding shell has an inclined sloped bottom plate, and one end of the feeding shell connected to the vibrating motor is higher than the other end where the discharge port is located.

[0021] In one embodiment, multiple fixing plates are provided on both sides of the base, and fixing holes are provided on the fixing plates.

[0022] The beneficial effects of this utility model are as follows:

[0023] (1) The turntable is driven by a servo motor to rotate intermittently, so that multiple positioning slots circulate through the detection mechanism and the automatic loading and unloading mechanism. When the detection head performs a test on a relay, the automatic loading and unloading mechanism simultaneously loads the relay to be tested into the empty positioning slot and pushes out the relay that has completed the test from another positioning slot, so that the detection and loading and unloading processes can be carried out in parallel. The equipment does not need to be paused to wait for material replacement throughout the process, which greatly improves the detection efficiency of the relay.

[0024] (2) The feeding shell has an inclined slope bottom plate. The vibration motor set at one end of the feeding shell will transport the relay to the discharge port at the other end of the feeding shell in an orderly manner. When the turntable rotates to the positioning groove aligned with the discharge port, the material will be automatically dropped, eliminating the manual operation time of the detection gap.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] This utility model provides a rapid detection device for multi-module relays, such as... Figure 1 As shown, the device includes a base 1, a detection component 2, and a detection mechanism 3 mounted on the base 1. The detection component 2 includes a servo motor 21 mounted inside the base 1. The output end of the servo motor 21 passes through the base 1 and is connected to a turntable 22. The turntable 22 has multiple positioning slots 23, the centers of which are located on the same circumference. The positioning slots 23 are used to place the relay to be detected. The detection mechanism 3 includes a mounting frame 31 connected to the base 1. An electric cylinder 32 is mounted on the mounting frame 31. The output end of the electric cylinder 32 is connected to a rotary motor 33. A detection head 34 is mounted on the bottom of the rotary motor 33. The output end of the electric cylinder 32 extends and retracts in the vertical direction. The detection head 34 is located above the turntable 22. An automatic loading and unloading mechanism 4 is also mounted on the base 1.

[0036] It should be noted that in this embodiment, the servo motor 21 drives the turntable 22 to rotate intermittently. The positioning slot 23 facilitates the placement of the relays to be tested. Multiple positioning slots 23 circulate through the detection mechanism 3 and the automatic loading and unloading mechanism 4. The automatic loading and unloading mechanism 4 synchronously loads the relays to be tested into the empty positioning slots 23. The relays rotate with the turntable 22 to the detection head 34, where the detection head 34 performs the detection operation. The electric cylinder 32 can adjust the height of the rotary motor 33 and the detection head 34. The rotary motor 33 drives the rotary head to adjust the angle so that the detection end point of the detection head 34 can make normal contact with the contacts of the relay, facilitating the detection of the relay. At the same time, the automatic loading and unloading mechanism 4 discharges the relays that have completed the detection from the turntable 22, realizing the parallel operation of the detection and loading and unloading process. The equipment does not need to be paused to wait for material replacement, which greatly improves the detection efficiency of the relays.

[0037] Furthermore, such as Figure 2 and Figure 4As shown, the automatic loading and unloading mechanism 4 includes a bracket 41 installed on one side of the top of the base 1. The bracket 41 is connected to a feeding shell 42. A vibration motor 43 is installed at one end of the feeding shell 42, and a discharge port located above the turntable 22 is opened at the bottom of the other end. The position of the discharge port corresponds to the positioning groove 23. The automatic loading and unloading mechanism 4 also includes a top material assembly 46 and a pusher plate 45 installed on the other side of the top of the base 1. The top material assembly 46 has a top rod 463 corresponding to the position of the positioning groove 23. The bracket 41 has an L-shaped structure, with one end connected to the top of the base 1 and the other end located above the turntable 22 and connected to the feeding shell 42.

[0038] It should be noted that the bracket 41 provides stable support for the feeding shell 42, which is used to smoothly transport the relay. When the positioning groove 23 is perpendicular to the discharge port, the relay passes through the discharge port and enters the positioning groove 23. When the two are not perpendicular, the relay stays in the feeding shell 42. The top material assembly 46 then uses the top rod 463 to discharge the relay that has completed the test from the positioning groove 23 and transfer it through the push plate 45.

[0039] In one embodiment, such as Figure 3 As shown, the automatic loading and unloading mechanism 4 also includes a drive motor 44 installed in the base 1. The output end of the drive motor 44 passes through the base 1 and is connected to the push plate 45.

[0040] In one embodiment, such as Figure 3 As shown, the top feeding assembly 46 includes a top feeding motor 461 installed in the base 1. The output end of the top feeding motor 461 is connected to a cam 462. A top rod 463 is located on the top of the cam 462. A spring 464 is also sleeved on the top rod 463. The top of the top rod 463 passes through the base 1 and is located below the turntable 22. That is, the top feeding motor 461 installed in the base 1 drives the cam 462 to rotate. The cam 462 acts on the top rod 463 to discharge the relay in the positioning groove 23. The spring 464 sleeved on the top rod 463 makes the top rod 463 quickly return to its original position.

[0041] Furthermore, the base 1 is also provided with a sliding rod and a sliding sleeve fitted on the sliding rod. The top and bottom of the sliding rod are connected to the inner wall of the base 1, and the sliding sleeve is connected to the top rod 463. That is, the sliding rod fixed in the base 1 is used to limit the top rod 463, so that it can move back and forth in the vertical direction more smoothly and prevent it from tilting or deviating during movement.

[0042] In one embodiment, such as Figure 1 and Figure 5As shown, an industrial camera 35 is also provided on the mounting bracket 31. The industrial camera 35 is electrically connected to the electric cylinder 32 and the rotary motor 33 respectively. That is, the industrial camera 35 is used to take pictures of the relay, and the rotary motor 33 and the electric cylinder 32 are controlled by the captured image information, so that the detection end point of the detection head 34 can quickly contact the relay contact point, thereby improving the detection efficiency.

[0043] In one embodiment, such as Figure 1 and Figure 5 As shown, a limit cylinder 5 is also installed on the device. The limit cylinder 5 has an output end that extends in the vertical direction. The output end of the limit cylinder 5 is connected to a friction plate 6. That is, the limit cylinder 5 is used to drive the friction plate 6 to move in the vertical direction. When the relay needs to be tested, the friction plate 6 is brought into contact with the turntable 22. The friction force is used to prevent it from rotating, so that it remains in a more stable state when it stops rotating, thereby improving the detection accuracy and avoiding the accidental rotation of the turntable 22 from affecting the detection effect of the detection head 34 on the relay.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the feeding shell 42 has an inclined slope bottom plate. One end of the feeding shell 42 connected to the vibration motor 43 is higher than the other end where the discharge port is set, which facilitates automatic feeding by the relay.

[0045] In one embodiment, such as Figure 1 As shown, multiple fixing plates are provided on both sides of the base 1, and fixing holes are provided on the fixing plates to facilitate fixing the base 1.

[0046] In one embodiment, a detection host is fixedly connected to the inner left side of the base 1. The detection host is used to record parameters. A control panel electrically connected to the detection host is also provided on one side of the base 1 to start or stop the detection operation of the relay. The control panel and the mounting bracket 31 are located on the two sides of the base 1 respectively. A discharge shell is provided on the right side of the top of the base 1. The position of the discharge shell corresponds to the position of the push plate 45. An information display is also provided on the right side of the top of the base 1. The information display is used to display the results in real time. The servo motor 21 drives the turntable 22 to rotate intermittently. When the limit cylinder 5 stops rotating, it controls the friction plate to contact the turntable 22. Multiple positioning slots 23 are evenly distributed on the turntable 22. That is, when the turntable 22 stops rotating, the ejector motor 461 can eject the relay in the corresponding positioning slot 23, realizing the parallel detection and loading / unloading process. The equipment does not need to be paused to wait for material change throughout the process, which greatly improves the detection efficiency.
