Description

Technical Field

[0001] The invention belongs to the technical field of relay calibration, and in particular relates to a calibration device and a relay based on the calibration device. Background Art

[0002] In modern industrial production, relays are an important electrical component and are widely used in control systems. In order to ensure the performance and reliability of relays, calibration is essential. However, the traditional relay calibration method mainly relies on manual operation, especially in the power room, where the plug-in and unplug calibration process of relays often requires workers to perform manually. This manual calibration method has many problems, the first of which is low efficiency. Due to the large number of relays, manual plug-in and unplugging and testing one by one is not only time-consuming and labor-intensive, but also prone to missed detection or misdetection due to human operational errors. In addition, the repetitive operation of manual calibration can easily cause worker fatigue, which in turn affects the accuracy and consistency of the calibration.

[0003] With the improvement of the level of industrial automation, how to improve the automation level of relay calibration and reduce manual intervention has become an urgent problem to be solved in the industry. The existing manual calibration method not only affects production efficiency, but also limits the expansion of the company's production capacity. At the same time, there are many uncontrollable factors in manual operation. The plugging and unplugging force and insertion angle of the relay during the calibration process may cause poor contact and affect the accuracy of the calibration results. Moreover, after long-term use, the contact points of the relay may be oxidized and worn, and manual calibration is difficult to detect these potential problems in time. Based on these factors, the industry urgently needs a relay calibration device that can be highly efficient and precise to solve the inefficiency problems in the existing technology. Therefore, the development of an automated calibration device that can adapt to relays of different specifications to improve calibration efficiency, accuracy and reliability has become a key demand of relay production and use companies. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a calibration device and a relay based on the calibration device. The specific technical solution is as follows:

[0005] The present invention provides an inspection device, which includes a conveying mechanism and a material transfer mechanism that are symmetrically arranged in a left-right staggered manner on the top surface of the machine table for the conveying and transfer of relays. A calibration component is horizontally connected between the opposite material transfer mechanisms. A horizontal cylinder and a vertical cylinder are provided on the back of the calibration component. A "冖"-shaped locking seat is erected on the top of the horizontal cylinder, and a limiting seat connected through a guide rail slider is attached to its front surface, which can reciprocate in the vertical direction. It is characterized in that a "口"-shaped hollow limiting frame is hung on the limiting seat, and a plurality of fixing clamps are vertically inserted into the cavity of the limiting frame. An inverted conical limiting thimble is inserted into the fixing clamp. A "山"-shaped calibration groove is fixedly arranged directly below the limiting frame, and the intermittent groove in the middle of the mountain is used for the inter-board of the relay and a calibration card board is clamped at its bottom. In addition, a locking plate extending from the pushing part of the horizontal cylinder is provided, and a locking port adapted to the width of the relay is opened at its front end, which can reciprocate horizontally along the end surface of the calibration groove. The calibration card board is provided with uniformly distributed calibration probes. In addition, a calibration cylinder is vertically embedded in the machine table, and its pushing part is connected to the calibration card board and can reciprocate in the vertical direction;

[0006] This inspection device is divided into a conveying state and an inspection state. When in the conveying state, the horizontal cylinder drives the locking plate to extend out to lock the relay to be inspected. The vertical cylinder drives the locking tooth plate to continuously move along the calibration groove until it reaches the calibration position, and the conveying ends. When in the inspection state, the limiting cylinder drives the limiting frame to move downward until the fixing clamp on it abuts against the relay to be inspected with the limiting thimble. The calibration cylinder below drives the calibration probe to move upward until the calibration probe contacts the pins at the bottom of the relay to conduct electricity, and the inspection ends.

[0007] As a preferred technical solution of the present invention, the conveying mechanism includes horizontally opposite conveying beams and follower wheels arranged between the beams. An "L"-shaped conveying seat is clamped below the conveying beams, and vertical sliding grooves are symmetrically opened thereon. A conveying wheel connected to a conveying motor is sleeved on the conveying seat. In addition, a conveyor belt is wrapped around the outer circumference of the conveying wheel and the follower wheel for the stable conveying of the relay.

[0008] As a preferred technical solution of the present invention, the material transfer mechanism includes a material transfer seat connected to the end of the conveying mechanism. A material transfer rail is erected at the end of the material transfer seat, and a clamp-shaped material transfer gripper is fixed thereon through a slide rail. A notch adapted to the calibration groove is opened inside the material transfer gripper, and a horizontal material transfer cylinder is connected to its end, which can insert and take the relay along the material transfer rail and transfer it horizontally to the feeding end and the discharging end of the calibration component for the cross-mechanism transfer of the relay.

[0009] As a preferred technical solution of the present invention, a waste mechanism is arranged on the side of the material moving mechanism at the material discharging end of the inspection component, which includes a return cylinder longitudinally suspended above the material moving gripper and an "L"-shaped aggregate hammer connected to its pushing part, the short end size of the aggregate hammer is adapted to the notch of the material moving gripper, and the relay in the notch of the material moving gripper can be pushed longitudinally, and a recycling box is erected under the material moving aggregate hammer for collecting and storing unqualified relays, and a pair of flat plates are erected on the inner side of the recycling box, the ends of which are connected to the aggregate cylinder, which can push the aggregate hammer horizontally to knock the unqualified relays into the recycling box for alignment;

[0010] When the unqualified relay is inserted into the material discharging end of the inspection component along with the locking plate and enters the material transfer gripper, the material transfer cylinder drives the material transfer gripper to retract along the material transfer rail. At the same time, the return cylinder drives the collecting hammer to retract and pushes the unqualified relay in the material transfer gripper to the inside of the recovery box. Then the collecting cylinder drives the flat plate to push the unqualified relay horizontally until it is flush.

[0011] As a preferred technical solution of the present invention, a material receiving mechanism is vertically arranged on the side of the waste mechanism, which includes an inverted "L"-shaped clamping frame vertically arranged on the opposite side of the recycling box, the clamping frame is vertically attached to a clamping plate through a guide rail slider, and its side end is horizontally connected to a first clamping cylinder, which can reciprocate in the horizontal direction, and a pneumatic clamp is vertically arranged on the clamping plate, and its end is connected to a second clamping cylinder, which can reciprocate in the vertical direction, and a spiral material receiving bin is arranged on the diagonally opposite side of the clamping frame for collecting and storing qualified relays;

[0012] When the qualified relay is transported out along the conveying mechanism, the pneumatic clamp on the clamping plate is pushed down by the first clamping cylinder, clamps the qualified relay and moves up, and then the second clamping cylinder drives the clamping plate to move horizontally to the top of the spiral collecting bin and stops. At the same time, the pneumatic clamp on the clamping plate is pushed down by the first clamping cylinder, puts down the qualified relay, and then moves up to return to the initial position to complete a single material collection.

[0013] As a preferred technical solution of the present invention, a shock absorbing mechanism is arranged on the opposite side of the inspection groove, which includes a base plate and a progressive plate thereon which are progressively driven by a guide rail slider, and a multi-stage cylinder is arranged thereon, and an elliptical shock absorbing tooth performs lateral reciprocating motion with the multi-stage cylinder, which is used to inspect the shock absorbing stability of the relay.

[0014] As a preferred technical solution of the present invention, the inner plate of the spiral material collecting bin is provided with a spiral track, which is inclined in a clockwise direction for the rapid storage of qualified relays.

[0015] As a preferred technical solution of the present invention, a spring is embedded in the limit ejector pin, which can reduce the impact when the limit frame moves downward and presses against the relay to be detected.

[0016] As a preferred technical solution of the present invention, the conveying motor is installed in the slide groove by bolts and can slide up and down along the slide groove to adjust the tightness of the conveyor belt.

[0017] As a preferred technical solution of the present invention, the relay is conveyed to the slot in the material moving gripper by the conveying motor driving the conveying belt on the conveying wheel, and at the same time, the material moving cylinder drives the material moving gripper to move along the material moving rail to the inspection slot and enter the locking mouth of the locking plate, and then the longitudinal cylinder drives the locking plate to move longitudinally along the inspection slot to reach the inspection position, and then the limit cylinder drives the limit frame to move vertically downward, so that the limit ejector pin and the fixing clamp thereon are pressed against the relay to be inspected, and the shock-absorbing teeth extended by the multi-stage cylinder lock the relay to be inspected, and at the same time, the inspection cylinder drives the inspection probe on the inspection card plate to move upward and lift for power-on inspection, and returns to its original position after completing multiple inspections, and then the longitudinal cylinder drives the relay on the locking plate to move longitudinally along the inspection slot to reach the discharge end; When the unqualified relay is inserted into the discharging end of the inspection component along with the locking plate and enters the material transfer gripper, the material transfer cylinder drives the material transfer gripper to retract into position along the material transfer rail. At the same time, the return cylinder drives the collecting hammer to retract into position and pushes the unqualified relay in the material transfer gripper to the inside of the recovery box. Then the collecting cylinder drives the flat plate to push the unqualified relay horizontally until it is flush. When the qualified relay is transported and discharged along the conveying mechanism, the pneumatic clamp on the clamping plate is pushed down by the first clamping cylinder, clamps the qualified relay and moves up. Then the second clamping cylinder drives the clamping plate to move horizontally to the top of the spiral collecting bin and stops. At the same time, the pneumatic clamp on the clamping plate is pushed down by the first clamping cylinder, puts down the qualified relay and moves up to return to the initial position to complete a single material collection.

[0018] The beneficial effects of the present invention are:

[0019] The calibration device has significant advantages in structural design and function, and effectively solves the problems of low efficiency and insufficient precision in the calibration process of relays in the prior art. First of all, from the perspective of improving the calibration efficiency, the device realizes the automatic conveying and transportation of relays through the conveying mechanism and material transfer mechanism that are symmetrically set up on the left and right. Compared with the traditional operation method that requires manual calibration or manual assistance, this design reduces human intervention through automated operation, greatly improving the overall work efficiency. During the conveying process, the relay can be quickly and accurately positioned in the calibration device through the coordinated cooperation of the horizontal cylinder and the longitudinal cylinder. In the calibration state, the limit cylinder drives the limit frame to press down, so that the relay is firmly fixed in the correct position to ensure the smooth progress of the calibration process. The overall mechanical automation process design enables multiple relays to be calibrated continuously, avoiding frequent shutdowns for maintenance, thereby greatly shortening the centralized calibration time.

[0020] Secondly, the device has significant advantages in improving calibration accuracy. The combination of the fixing clamp on the limit frame and the inverted cone limit pin ensures the precise locking of the relay position during the calibration process, avoiding calibration errors caused by loosening and offset of the relay. In addition, the matching structure between the "mountain"-shaped hollow calibration groove under the device and the relay enables the relay to be accurately aligned in the calibration groove, further improving the positioning accuracy. The design of the calibration probe effectively enhances the calibration accuracy. Through this precise contact method, the calibration probe can ensure accurate electrical contact and testing of each pin of the relay, avoiding errors caused by poor contact during the test. The control of the entire process is based on the stability of the mechanical structure and the reciprocating linear motion of the pneumatic components, ensuring that each calibration step of the relay can be completed under high-precision conditions.

[0021] In summary, the calibration device achieves efficient calibration through automated conveying and transfer mechanisms, reduces manual operation time, and significantly improves production efficiency. At the same time, relying on a precise positioning system, a stable limit device, and a high-precision calibration probe design, the high accuracy of the calibration process is ensured, avoiding errors that may occur in traditional manual calibration. The device integrates efficient and high-precision calibration functions, greatly optimizes the calibration process of relays, greatly shortens the downtime maintenance period, and protects industrial safety.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Embodiment 1

[0033] In order to solve the technical problems in the background technology, a calibration device and a relay based on the calibration device are provided as follows:

[0034] Combination Figure 1-6As shown in the figure, an inspection device includes a conveying mechanism 1 and a material transfer mechanism 2 that are symmetrically arranged in a left-right staggered manner on the top surface of the machine table 6, which are used for the conveying and transfer of relays. A calibration component is horizontally connected between the relative positions of the material transfer mechanism 2. A horizontal cylinder 31 and a vertical cylinder 32 are provided on the back of the calibration component. A "冖"-shaped locking seat 33 is erected on the top of the horizontal cylinder 31. A limiting seat 362 connected by a guide rail slider is attached to its front surface, which can reciprocate in the vertical direction. It is characterized in that the limiting seat 362 is hung with a "口"-shaped hollow limiting frame 363, and a plurality of fixed clamps 3632 are vertically inserted into the cavity of the limiting frame 363. An inverted conical limiting thimble 3631 is inserted into the fixed clamp 3632. A "山"-shaped calibration groove is fixedly provided directly below the limiting frame 363. The mountain-shaped groove is intermittently penetrated, which is used for the inter-board of the relay and a calibration card plate 352 is clamped at its bottom. In addition, a locking plate 34 extending from the pushing part of the horizontal cylinder 31 is provided, and a locking port 341 adapted to the width of the relay is opened at its front end, which can reciprocate horizontally along the end surface of the calibration groove. The calibration card plate 352 is provided with uniformly distributed calibration probes 353. In addition, a calibration cylinder is vertically embedded in the machine table 6, and its pushing part is connected to the calibration card plate 352, which can reciprocate in the vertical direction;

[0035] This inspection device is divided into a conveying state and an inspection state. When in the conveying state, the horizontal cylinder 31 drives the locking plate 34 to extend out to lock the relay to be inspected. The vertical cylinder 32 drives the locking tooth plate to continuously move along the calibration groove until it reaches the calibration position, and the conveying ends. When in the inspection state, the limiting cylinder 361 drives the limiting frame 363 to move downward until the fixed clamp 3632 on it abuts against the limiting thimble 3631 to firmly hold the relay to be inspected. The calibration cylinder 351 below drives the calibration probe 353 to move upward until the calibration probe 353 contacts the pins at the bottom of the relay to be energized, and the inspection ends.

[0036] By the above technical means, first of all, from the perspective of improving the inspection efficiency, the device realizes the automatic conveying and transfer of relays through the conveying mechanism 1 and the material transfer mechanism 2 arranged in a left-right staggered and symmetrical manner. Compared with the traditional operation methods that require manual inspection or manual assistance, this design reduces human intervention through automatic operation and greatly improves the overall work efficiency. During the conveying process, through the coordinated cooperation of the horizontal cylinder 31 and the vertical cylinder 32, the relay can be quickly and accurately positioned in the inspection device. In the inspection state, the limiting cylinder 361 drives the limiting frame 363 to press down, so that the relay is firmly fixed in the correct position to ensure the smooth progress of the inspection process. The overall mechanical automation process design enables multiple relays to be continuously inspected, avoiding frequent shutdowns for maintenance, thereby greatly shortening the centralized inspection time.

[0037] Secondly, the device has significant advantages in improving calibration accuracy. The combination of the fixing clamp 3632 on the limit frame 363 and the inverted cone limit pin 3631 ensures the precise locking of the position of the relay during the calibration process, avoiding calibration errors caused by loosening and displacement of the relay. In addition, the matching structure between the "mountain"-shaped hollow calibration groove under the device and the relay enables the relay to be accurately aligned in the calibration groove, further improving the positioning accuracy. The design of the calibration probe 353 effectively enhances the calibration accuracy. Through this precise contact method, the calibration probe 353 can ensure accurate electrical contact and testing of each pin of the relay, avoiding errors caused by poor contact during the test. The control of the entire process is based on the stability of the mechanical structure and the reciprocating linear motion of the pneumatic components, ensuring that each calibration step of the relay can be completed under high-precision conditions.

[0038] In summary, the calibration device achieves efficient calibration through automated conveying and transfer mechanisms, reduces manual operation time, and significantly improves production efficiency. At the same time, relying on the precise positioning system, stable limit device and high-precision calibration probe 353 design, the high accuracy of the calibration process is ensured, avoiding errors that may occur in traditional manual calibration. The device integrates efficient and high-precision calibration functions, greatly optimizes the calibration process of relays, greatly shortens the downtime maintenance period, and protects industrial safety.

[0039] Embodiment 2

[0040] like Figure 1-3 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the conveying mechanism 1 includes a conveying beam 11 that is horizontally arranged opposite to each other and a rotating follower wheel 15 that is inserted between the beams. An "L"-shaped conveying seat 12 is clamped below the conveying beam 11, and vertical slide grooves 121 are symmetrically opened on the conveying seat 12. A conveying wheel 13 connected to a conveying motor is sleeved on the conveying seat 12, and a conveyor belt 14 is wrapped around the outer periphery of the conveying wheel 13 and the rotating follower wheel 15 for smooth transportation of relays.

[0042] The material transfer mechanism 2 includes a material transfer seat 21 connected to the end of the conveying mechanism 1, and a material transfer rail 24 is set at the end of the material transfer seat 21, on which a clamp-shaped material transfer gripper 23 is fixed by a slide rail. A slot 231 adapted to the inspection slot is opened inside the material transfer gripper 23, and a transverse material transfer cylinder 22 is connected at its end. The relay can be inserted along the material transfer rail 24 to transversely transfer the material to the feed end and the discharge end of the inspection component 3 for cross-mechanism transportation of the relay.

[0043] The conveying motor is installed in the slide groove 121 by bolts, and can slide up and down along the slide groove 121 to adjust the tightness of the conveying belt 14.

[0044] Through the above-mentioned technical means, with the help of the automated conveying mechanism 1 and the instant material transfer mechanism 2, the full process of relay automation from conveying to inspection and then to transportation is realized, which greatly improves the inspection efficiency. Compared with the traditional manual inspection method, the biggest advantage of this device lies in its efficient conveying and transportation capabilities. The conveying mechanism 1 adopts a combination design of a conveying beam 11, a rotating wheel 15 and a conveyor belt 14, which can ensure that the relay maintains a stable and continuous movement during the entire conveying process, and can also adjust the tightness of the conveyor belt 14 in real time, avoiding problems such as jamming and falling that may occur during manual operation. It not only reduces the frequency of manual intervention, but also greatly shortens the transmission time of the relay from the production line to the inspection station, further improving the inspection operation efficiency.

[0045] In addition, the design of the material transfer mechanism 2 also has significant advantages. The material transfer gripper 23 realizes the precise transfer of relays between different stations by cooperating with the material transfer cylinder 22. The notch 231 inside the gripper is highly adapted to the inspection slot. The notch 231 of the reciprocating material transfer gripper 23 must be used to complete the transfer and delivery of the lock port 341 relay (bidirectional delivery of the conveying mechanism and the inspection mechanism), ensuring the stable delivery of the relay during the feeding and discharging process, and avoiding the damage of the relay caused by improper grasping. Compared with manual operation, the automated gripper can complete the lateral material transfer of the relay at a faster speed and higher precision, avoiding errors and instability in manual operation. This high-precision grasping and material transfer design ensures that the relay can enter the inspection station accurately, greatly improving the reliability of the inspection process.

[0046] In summary, the beneficial effects of the device are mainly reflected in the following aspects: automated conveying and transportation greatly improves the transmission efficiency of the relay and reduces the time consumption of manual operation; secondly, the high-precision design of the material transfer mechanism 2 ensures the stability and accuracy of the relay during transportation, avoiding errors and unstable factors in manual operation. Through these design optimizations, the device can significantly improve the overall efficiency and accuracy of relay calibration, achieve seamless connection before and after calibration, avoid interruptions and delays in manual operation, and ensure the smooth progress of calibration.

[0047] Embodiment 3

[0048] like Figure 6-8 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0049] In this embodiment, a waste mechanism 4 is arranged on the side of the material transfer mechanism 2 at the discharge end of the inspection component 3, which includes a return cylinder 41 longitudinally suspended above the material transfer gripper 23 and an "L"-shaped aggregate hammer 42 connected to its pushing part, the short end size of the aggregate hammer 42 is adapted to the notch 231 of the material transfer gripper 23, and the relay in the notch 231 of the material transfer gripper 23 can be pushed longitudinally, and a recycling box 43 is set under the material transfer aggregate hammer 42 for collecting and storing unqualified relays, and a pair of flat plates 45 are erected on the inner side of the recycling box 43, and the end of the flat plate 45 is connected to a material collection cylinder 44, which can push the aggregate hammer 42 horizontally to knock the unqualified relays in the recycling box 43 into alignment;

[0050] When the unqualified relay is inserted into the discharging end of the inspection component 3 along the locking plate 34 and enters the material transfer gripper 23, the material transfer cylinder 22 drives the material transfer gripper 23 to retract along the material transfer rail 24. At the same time, the return cylinder 41 drives the collecting hammer 42 to retract and push the unqualified relay in the material transfer gripper 23 to the inside of the recovery box 43. Then the collecting cylinder 44 drives the flat plate 45 to push the unqualified relay horizontally to be flush.

[0051] A material collecting mechanism 5 is provided on the side of the waste mechanism 4, which includes an inverted "L"-shaped clamping frame 51 provided on the opposite side of the recycling box 43, and the clamping frame 51 is vertically attached with a clamping plate 54 through a guide rail slider, and a first clamping cylinder 52 is horizontally connected to the side end thereof, which can reciprocate in the horizontal direction, and a pneumatic clamp 55 is vertically arranged on the clamping plate 54, and a second clamping cylinder 53 is connected to the end thereof, which can reciprocate in the vertical direction for clamping, and a spiral material collecting bin 56 is provided on the obliquely opposite side of the clamping frame 51, which is used to collect and store qualified relays;

[0052] When the qualified relay is transported and discharged along the conveying mechanism 1, the pneumatic clamp 55 on the clamping plate 54 is pushed down by the first clamping cylinder 52, clamps the qualified relay and moves up, and then the second clamping cylinder 53 drives the clamping plate 54 to move horizontally to the top of the spiral collecting bin 56 and stop. At the same time, the pneumatic clamp 55 on the clamping plate 54 is pushed down by the first clamping cylinder 52, puts down the qualified relay and then moves up to the initial position to complete a single material collection.

[0053] The inner plate of the spiral storage bin 56 is provided with a spiral track which is inclined in a clockwise direction for quickly storing qualified relays.

[0054] Through the above-mentioned technical means, efficient packaging of qualified and unqualified relays is achieved, solving the problems of low sorting efficiency and poor precision in traditional manual inspection. On the one hand, through the linkage operation of the return cylinder 41 and the aggregate hammer 42, the unqualified relays can be quickly pushed into the recycling box 43 after the inspection is completed, and further aligned by the flat plate 45 of the aggregate cylinder 44, ensuring that the unqualified relays can be neatly and orderly stacked in the recycling box 43, which not only avoids errors and omissions in manual operation, but also greatly improves the sorting efficiency. In traditional manual inspection, workers need to manually identify and sort unqualified relays, which is prone to missed selection and misjudgment, while the waste mechanism 4 ensures that the sorting process is fast and error-free through the close linkage of mechanical and pneumatic systems.

[0055] On the other hand, the material collecting mechanism 5 is specifically used for the automatic collection of qualified relays. Through the cooperation of the pneumatic pliers 55 and the clamping cylinder, the qualified relays can be accurately clamped and stored in order through the spiral material collecting bin 56. Compared with manual operation, the automated clamping system can complete the grasping and releasing of relays with higher accuracy and speed, avoiding the unstable grasping and inaccurate placement that may occur in manual operation. At the same time, the structural design of the spiral material collecting bin 56 ensures that the qualified relays can be arranged in a certain order, and the oblique track helps the automatic stacking of qualified relays, which is convenient for subsequent processing, not only improving the packaging efficiency, but also ensuring the safety and integrity of the relays during the material collecting process, avoiding damage or confusion of the relays that may be caused by manual operation.

[0056] To sum up, the automated waste mechanism 4 and receiving mechanism 5 can quickly and accurately complete the packaging of unqualified and qualified relays, avoiding errors in manual operation; secondly, the high-precision design of the mechanical system ensures the stability and safety of the relays during the packaging process, reducing the risk of damage to the relays; finally, the automated packaging system can greatly improve the overall efficiency of the production line, reduce the time and cost of manual operation, ensure the efficiency and reliability of the relay packaging process, effectively solve the inefficient classification in traditional manual inspection, and significantly improve the efficiency of relay inspection and packaging.

[0057] Embodiment 4

[0058] like Figure 4-6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0059] In this embodiment, a shock absorbing mechanism 37 is mounted on the opposite side of the calibration groove, which includes a base plate 372 and a progressive plate 373 thereon which are progressively driven by a guide rail slider, and a multi-stage cylinder 371 is mounted thereon, and an elliptical shock absorbing tooth 374 moves laterally back and forth with the multi-stage cylinder 371, which is used to calibrate the shock absorbing stability of the relay.

[0060] A spring is embedded in the limiting ejector pin 3631 to reduce the impact when the limiting frame 363 moves downward and presses against the relay to be detected.

[0061] Through the above-mentioned technical means, the accuracy and stability of the relay calibration process are significantly improved. First, the combination design of the multi-stage cylinder 371 and the elliptical shock-absorbing teeth 374 in the shock-absorbing mechanism 37 can effectively reduce vibration and impact during the relay calibration process, thereby ensuring the stability of the relay in the test position. In the traditional manual calibration process, due to the uncontrollability of human operation, the relay is easily disturbed by external forces during calibration, resulting in inaccurate test results. The shock-absorbing mechanism 37 ensures the stability of the relay throughout the calibration process through a mechanized shock-absorbing design, avoiding the influence of vibration on the test accuracy.

[0062] Secondly, the spring structure embedded in the limit pin 3631 can effectively buffer the pressure when the relay is pressed by the limit frame 363, avoiding damage to the relay caused by excessive impact force. At the same time, this buffer design can also ensure that the relay maintains a stable contact state during the pressing process, further improving the accuracy and reliability of the calibration. Compared with the roughness of manual operation, this progressive shock absorption and buffer design can provide more precise force control, thereby ensuring that the relay calibration process is more accurate and stable.

[0063] The working principle and use process of the present invention:

[0064] Phase 1: Transport Phase

[0065] During the conveying stage, the relay is smoothly conveyed by the conveying mechanism 1. The conveying mechanism 1 is composed of a conveying beam 11, a rotating wheel 15 and a conveyor belt 14. The conveying motor drives the conveying wheel 13 to drive the conveyor belt 14 to run, and the relay is conveyed to the slot 231 of the material transfer gripper 23. At this time, the material transfer cylinder 22 is started, driving the material transfer gripper 23 to move horizontally along the material transfer track 24, and the relay is sent from the conveying end to the position of the locking plate 34 of the calibration component 3, and inserted into the locking port 341 of the locking plate 34. The horizontal cylinder 31 drives the locking plate 34 to extend, fix the relay to be calibrated, and ensure that it will not move during the calibration process.

[0066] Phase 2: Verification

[0067] When the relay reaches the calibration position, the calibration process officially begins. The longitudinal cylinder 32 is started, driving the locking plate 34 to move longitudinally along the calibration groove to the calibration position, and the relay is accurately positioned. Subsequently, the limit cylinder 361 drives the limit frame 363 to move vertically downward, and the fixing clamp 3632 and the limit ejector pin 3631 on the limit frame 363 contact the relay, and the spring structure is used for buffering to ensure that the relay is firmly fixed. At the same time, the multi-stage cylinder 371 pushes the shock-absorbing tooth 374 to lock the relay laterally, further improving the stability of the calibration process. Next, the calibration cylinder 351 drives the calibration probe 353 on the calibration card 352 to move upward and contact the pins of the relay to complete the power-on calibration. The calibration probe 353 is powered on to detect the various performance parameters of the relay one by one to ensure that the relay functions normally. After the calibration is completed, the cylinder is reset and the relay is unlocked.

[0068] The third stage: sorting stage

[0069] After the inspection, the state of the relay is determined to be qualified or unqualified. For unqualified relays, the locking plate 34 sends them to the discharge end of the inspection component 3, and the material transfer cylinder 22 drives the material transfer gripper 23 to move them out of the inspection slot and send them to the waste mechanism 4. The return cylinder 41 is started, driving the collection hammer 42 to push the unqualified relays into the recycling box 43. Subsequently, the collection cylinder 44 drives the flat plate 45 to move horizontally, aligning the unqualified relays in the recycling box 43 to ensure that the unqualified relays are stacked in an orderly manner.

[0070] The fourth stage: material collection

[0071] For qualified relays, the conveying mechanism 1 continues to convey them to the receiving mechanism 5. The receiving mechanism 5 automatically clamps qualified relays through the inverted "L"-shaped clamping frame 51 and the pneumatic clamp 55. The first clamping cylinder 52 drives the pneumatic clamp 55 to move downward, clamp the qualified relay and then move upward. Then the second clamping cylinder 53 is started to drive the clamping frame 51 to move horizontally to the top of the spiral receiving bin 56. The clamping cylinder moves downward again, and puts the qualified relay into the spiral receiving bin 56. A clockwise inclined spiral track is provided in the spiral receiving bin 56, which uses gravity to quickly and orderly collect qualified relays.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
