Description

Technical Field

[0001] This utility model belongs to the field of contactor technology, and in particular relates to a device for detecting the energization status of contactor terminals. Background Technology

[0002] In industrial automation and power systems, contactors, as critical electrical control components, directly impact the safety of the entire circuit system through their operational stability. The energization status of contactor terminals is a core indicator of their normal operation. Loosening or oxidation of terminals leading to abnormal energization can cause equipment shutdowns, production interruptions, and even safety accidents. Therefore, efficient and accurate detection of contactor terminal energization status is a crucial requirement in this field. Traditional manual inspection methods, where operators use handheld tools to individually inspect each terminal, meet basic requirements but are limited by the efficiency bottleneck of manual operation, making them unsuitable for batch inspection scenarios. While some automated inspection devices exist, the loading / unloading and inspection processes are sequential; when inspection is performed, loading and unloading operations must wait, leaving room for improvement in overall inspection efficiency.

[0003] Existing automated testing devices often employ rigid clamping or limited adjustment designs, making it difficult to adapt to the positioning requirements of contactors of different specifications. This can easily lead to poor contact between the testing contacts and terminals due to clamping misalignment, affecting the accuracy of the testing data. In addition, the station switching efficiency is low, and the fixed station design prevents testing and loading / unloading operations from being performed in parallel. During batch testing, the equipment idle time accounts for a high percentage, which restricts the overall testing efficiency.

[0004] To address this issue, we provide a contactor terminal energization status detection device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a contactor terminal energization status detection device. Through the cooperation of a rotating mechanism, a quick positioning mechanism and a detection mechanism, it solves the problems of the existing clamping structure being unable to adapt to the positioning requirements of contactors of different specifications and the low efficiency of workstation switching.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a contactor terminal energization status detection device, comprising a work box, a rotating mechanism on the top of the work box, a quick positioning mechanism on the top of the rotating mechanism, and a detection mechanism at the rear end of the top of the work box. The quick positioning mechanism includes an operating table on the top of the work box, with positioning platforms fixedly connected to both the front and rear ends of the top of the operating table. A partition is fixedly connected to the inner cavity of the positioning platform, and sliding rods are fixedly connected to both sides of the partition. A connecting frame is slidably connected to the surface of the sliding rod, and a spring is fitted on the surface of the sliding rod and on one side of the connecting frame. One side of the connecting frame penetrates the inner cavity of the positioning platform and extends to the outside of the positioning platform. A clamping seat is fixedly connected to one side of the connecting frame, and a buffer pad is fixedly connected to one side of the clamping seat. The positioning platform is used to place the contactor to be tested. The partition separates the sliding rods on both sides, and the sliding rods provide guidance for the sliding of the connecting frame, ensuring that the connecting frame can move stably along a fixed direction. The spring has... With elastic reset capability, when the contactor is placed on the positioning platform, the connecting frame moves along the slide bar towards the partition under the contactor's pressure, compressing the spring. The spring's elasticity reacts on the connecting frame, causing it to drive the clamping seat to tightly adhere to the contactor, achieving automatic clamping. The clamping seat directly contacts the contactor, fixing it from both sides through two opposing clamping seats. The buffer pad on one side of the clamping seat is made of a material with a certain degree of elasticity. During clamping, it avoids hard collisions between the clamping seat and the contactor, protecting the contactor surface from damage, and increases the friction between them, further improving clamping stability and preventing displacement of the contactor during testing. This quick positioning mechanism eliminates the need for manual adjustment of the clamping force, achieving adaptive clamping through the spring's elasticity. It can adapt to contactors of different sizes, greatly simplifying the operation process while ensuring the contactor's positional accuracy during testing, creating favorable conditions for precise testing by the testing mechanism.

[0008] The present invention is further configured such that the rotating mechanism includes a mounting groove, which is formed in the inner cavity of the work box. A rotating rod is movably connected to the bottom of the inner cavity of the mounting groove via a bearing. A first gear is fixedly connected to the surface of the rotating rod. A motor is fixedly connected to one side of the bottom of the inner cavity of the mounting groove. A second gear is fixedly connected to the output end of the motor. The second gear meshes with the first gear. The top of the rotating rod is fixedly connected to the operating table. The motor is driven by the meshing of the second gear and the first gear. This mechanical transmission method has high transmission efficiency and precision, and can accurately control the rotation angle and speed of the rotating rod, ensuring that the operating table drives the positioning table to accurately switch positions, realizing seamless connection between loading / unloading and inspection processes, and greatly improving the continuous operation capability of the device.

[0009] The present invention is further configured such that the detection mechanism includes a fixed plate, the bottom of the fixed plate is fixedly connected to the working box, a column is fixedly connected to the top of the fixed plate, a mounting base is fixedly connected to the top of the column, a cylinder is fixedly connected to one side of the top of the mounting base, and a detector is fixedly connected to the bottom of the cylinder. The cylinder, as a driving component, can drive the detector to move smoothly up and down, and flexibly adjust the position of the detector according to the height of the contactor, ensuring that the detector and the terminal are in close contact with appropriate force. This ensures stable transmission of the detection signal, avoids damage to the terminal, and improves the reliability of the detection.

[0010] The present invention is further configured such that a back plate is fixedly connected to the surface of the mounting base, and a display screen is fixedly connected to the surface of the back plate. The back plate provides reliable mounting support for the display screen, enabling the display screen to be stably positioned in a position easily observed by the operator, thus preventing the display screen from shaking or falling during device operation. The display screen can present the terminal power status information obtained by the detector in an intuitive way.

[0011] The present invention is further configured such that limit blocks are fixedly connected to both the front and rear ends of the top of the positioning platform. The limit blocks are symmetrically arranged and can guide and constrain the contactor during placement, so that the operator can place the contactor in the preset detection position without repeated calibration, thereby reducing human error.

[0012] The present invention is further configured such that a door is hinged to the surface of the work box, and a handle is fixedly connected to one side of the door surface. The door is hinged and can be opened and closed flexibly. When closed, it can form a closed space, effectively preventing dust, moisture and other substances from entering the work box, protecting the internal electrical components and transmission parts from corrosion and extending their service life.

[0013] The present invention is further configured such that support columns are fixedly connected to the four corners of the bottom of the work box, and the bottom of the support columns is provided with anti-slip texture. The support columns raise the entire device, so that the bottom of the work box is kept at a certain distance from the ground, avoiding direct contact between the ground water and stains and the work box, and reducing the corrosion and wear of the bottom of the work box.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves stable clamping of the contactor through a quick positioning mechanism. The sliding rod and spring in the positioning table cooperate to enable the connecting frame to drive the clamping seat to have elastic adjustment capability, which can adapt to the shape and size of contactors of different specifications. The buffer pad can not only avoid damage to the contactor surface during clamping, but also enhance the clamping stability. At the same time, the symmetrical design of the limit block provides precise guidance for contactor loading, reducing manual adjustment time, and fundamentally solving the problems of insufficient positioning accuracy and poor adaptability of traditional devices.

[0016] 2. This utility model achieves parallelization of the detection process through a rotating mechanism and a dual-station design. The motor drives the rotating rod to rotate the operating table through gear transmission, so that the two positioning tables can alternately be in the detection position and the loading / unloading position. When the detection mechanism detects the contactor on one of the positioning tables, the operator can complete the loading / unloading operation on the other positioning table, eliminating the waiting time of the traditional fixed station and significantly improving the equipment utilization rate in batch detection scenarios.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1 Please see Figure 1-5 This utility model is a contactor terminal energization status detection device, including a working box 1. A rotating mechanism 2 is provided on the top of the working box 1. A quick positioning mechanism 3 is provided on the top of the rotating mechanism 2. A detection mechanism 4 is provided at the rear end of the top of the working box 1. The quick positioning mechanism 3 includes an operating table 31, which is located on the top of the working box 1. A positioning table 32 is fixedly connected to both the front end and the rear end of the top of the operating table 31. A partition 33 is fixedly connected to the inner cavity of the positioning table 32. A sliding rod 34 is fixedly connected to both sides of the partition 33. A connecting frame 35 is slidably connected to the surface of the sliding rod 34. A spring 36 is sleeved on the surface of the sliding rod 34 and on one side of the connecting frame 35. One side of the connecting frame 35 penetrates the inner cavity of the positioning table 32 and extends to the outside of the positioning table 32. A clamping seat 37 is fixedly connected to one side of the connecting frame 35. A buffer pad 38 is fixedly connected to one side of the clamping seat 37.

[0026] Specifically: the positioning platform 32 is used to place the contactor to be tested. The partition 33 separates the slide bar 34 on both sides. The slide bar 34 provides guidance for the sliding of the connecting frame 35, ensuring that the connecting frame 35 can move stably along a fixed direction. The spring 36 has elastic restoring capability. When the contactor is placed on the positioning platform 32, the connecting frame 35 will move along the slide bar 34 towards the partition 33 under the pressure of the contactor. The spring 36 is compressed, and the elastic force of the spring 36 will react on the connecting frame 35, causing the connecting frame 35 to drive the clamping seat 37 to tightly fit against the contactor, realizing automatic clamping of the contactor. The clamping seat 37 directly contacts the contactor, through two oppositely arranged clamps. The seat 37 secures the contactor from both sides. The buffer pad 38 on one side of the seat 37 is made of a material with a certain degree of elasticity. During the clamping process, it can not only avoid hard collisions between the seat 37 and the contactor, protecting the contactor surface from damage, but also increase the friction between the two, further improving the stability of the clamping and preventing the contactor from shifting during the testing process. This quick positioning mechanism 3 does not require manual adjustment of the clamping force. It achieves adaptive clamping through the elastic force of the spring 36, which can adapt to contactors of different sizes, greatly simplifying the operation process. At the same time, it ensures the accuracy of the contactor's position during testing, creating favorable conditions for the accurate testing of the testing mechanism 4.

[0027] Example 2 Please see Figure 1-5Based on Embodiment 1, the rotating mechanism 2 includes a mounting groove 21, which is formed in the inner cavity of the work box 1. A rotating rod 22 is movably connected to the bottom of the inner cavity of the mounting groove 21 via a bearing. A first gear 23 is fixedly connected to the surface of the rotating rod 22. A motor 24 is fixedly connected to one side of the bottom of the inner cavity of the mounting groove 21. A second gear 25 is fixedly connected to the output end of the motor 24, and the second gear 25 meshes with the first gear 23. The top of the rotating rod 22 is fixedly connected to the operating table 31. The detection mechanism 4 includes a fixing plate 41, the bottom of which is fixedly connected to the work box 1, and the top of which is fixedly connected to the work box 1. A column 42 is fixedly connected, and a mounting base 43 is fixedly connected to the top of the column 42. A cylinder 44 is fixedly connected to one side of the top of the mounting base 43. A detector 45 is fixedly connected to the bottom of the cylinder 44. A back plate 5 is fixedly connected to the surface of the mounting base 43. A display screen 6 is fixedly connected to the surface of the back plate 5. Limiting blocks 7 are fixedly connected to the front and rear ends of the top of the positioning platform 32. The limiting blocks 7 are symmetrically arranged. A door 8 is hinged to the surface of the work box 1. A handle is fixedly connected to one side of the surface of the door 8. Support columns 9 are fixedly connected to the four corners of the bottom of the work box 1. The bottom of the support columns 9 is provided with anti-slip texture.

[0028] Specifically: Motor 24 is driven by the meshing of the second gear 25 and the first gear 23. This mechanical transmission method has high transmission efficiency and precision, and can accurately control the rotation angle and speed of the rotating rod 22, ensuring that the operating table 31 drives the positioning table 32 to accurately switch positions, realizing seamless connection between loading / unloading and inspection processes, and greatly improving the continuous operation capability of the device. Cylinder 44, as a driving component, can drive the detector 45 to move smoothly up and down. The position of detector 45 can be flexibly adjusted according to the height of the contactor to ensure that detector 45 makes close contact with the terminal with appropriate force, which not only ensures the stable transmission of detection signals, but also avoids damage to the terminal, improving the reliability of detection. The back plate 5 provides reliable mounting support for display screen 6, so that display screen 6 can be stably positioned for easy observation by the operator. The placement of the display screen 6 prevents it from shaking or falling during device operation. The display screen 6 can present the terminal energization status information obtained by the detector 45 in an intuitive way. The limit block 7 can guide and constrain the contactor during placement, allowing the operator to place the contactor in the preset detection position without repeated calibration, reducing human error. The door 8 is hinged and can be opened and closed flexibly. When closed, it forms a closed space, effectively preventing dust, moisture and other substances from entering the interior of the working box 1, protecting the internal electrical components and transmission parts from corrosion and extending their service life. The support column 9 raises the entire device, keeping the bottom of the working box 1 a certain distance from the ground, preventing water and dirt from directly contacting the working box 1, and reducing corrosion and wear on the bottom of the working box 1.

[0029] The working principle of this utility model is as follows: The operator places the contactor to be tested on one of the positioning platforms 32 on the top of the operating table 31. During the placement process, the limiting block 7 plays a guiding and constraining role, so that the contactor is quickly placed in the preset testing position. After the contactor is placed in place, it will squeeze the clamping seats 37 on both sides. The clamping seats 37 drive the connecting frame 35 to move along the slide rod 34 towards the partition plate 33. At this time, the spring 36 on the surface of the slide rod 34 is compressed. The elastic restoring force of the spring 36 acts on the connecting frame 35, so that the connecting frame 35 drives the clamping seats 37 to tightly fit against both sides of the contactor, realizing automatic clamping of the contactor. The buffer pad 38 on one side of the clamping seat 37 avoids hard collisions during the clamping process, while increasing the friction to ensure that the contactor is stably fixed, providing a precise positional basis for subsequent testing.

[0030] After loading and positioning are completed, the motor 24 is started, which drives the second gear 25 to rotate. Since the second gear 25 meshes with the first gear 23 on the surface of the rotating rod 22, the rotating rod 22 is driven to rotate stably in the mounting groove 21 through the bearing. The top of the rotating rod 22 is fixedly connected to the operating table 31, which in turn drives the operating table 31 and the positioning table 32 to rotate precisely, moving the positioning table 32 with the contactor to be tested to the bottom of the testing mechanism 4. At the same time, the contactor that has been tested on the other side is moved to the loading and unloading position, realizing seamless switching between loading and unloading and testing processes.

[0031] When the contactor to be tested reaches the testing position, the cylinder 44 drives the detector 45 at the bottom to move downwards, adjusting it to a suitable position according to the height of the contactor, so that the detector 45 makes close contact with the terminals of the contactor with appropriate force. At this time, the detector 45 collects the energization status signal of the terminals, such as current, voltage and other information, and transmits the signal to the relevant processing components. The display screen 6 on the back plate 5 of the mounting base 43 receives the processed test information and presents the energization status of the terminals in an intuitive way. The operator can view the test results in real time through the display screen 6 and quickly determine whether the contactor is qualified.

[0032] After the test is completed, the rotating mechanism 2 is restarted to move the tested contactor to the loading and unloading position. The operator removes the tested contactor and places a new contactor to be tested on the empty positioning table 32 to enter the next test cycle.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
