Description

Technical Field

[0001] The utility model relates to the technical field of relays, and particularly relates to a relay reed correction device and a relay calibration device. Background Technique

[0002] A relay is an electrical device used to control a circuit. It triggers the flow of one or more larger currents (outputs) by receiving an electrical signal (input). The main functions of this device are to amplify signals, isolate circuits, or convert signals, enabling the control circuit to remotely or safely operate high-current loads. Relays are widely used in automated control systems, household appliances, automotive electronics, industrial equipment, and safety systems, and are key components for realizing electrical control and protection.

[0003] The reed of a relay is one of its core components, usually made of elastic metal material, and is responsible for realizing the switching function in the circuit. The elasticity of the reed enables the relay to quickly respond when receiving a control signal, closing or opening the circuit through mechanical actions, thereby controlling a larger current or voltage. The design and material of the reed directly affect the contact reliability, response speed, and durability of the relay. Therefore, the design, manufacture, and maintenance of the reed are crucial for ensuring the performance of the relay.

[0004] The skew of the relay reed during the production process will affect the reliability of its electrical contact and the accuracy of mechanical actions. The skew reed may cause poor contact, unstable signal transmission, or mechanical jamming, thereby affecting the performance and service life of the entire relay. Therefore, it is necessary to correct it to ensure the flatness and alignment of the reed, so as to ensure that the relay can work stably and reliably under various working conditions.

[0005] In the related art, the correction of the relay reed generally uses manual operation of a correction jig to correct it, but using this correction method cannot control the correction angle of the reed, which may lead to the problem that the requirements are still not met after correction.

[0040] A relay is an electrical device used to control a circuit. It triggers the flow of one or more larger currents (output) by receiving an electrical signal (input). The main functions of this device are to amplify signals, isolate circuits, or convert signals, enabling the control circuit to remotely or safely operate high-current loads. Relays are widely used in automated control systems, household appliances, automotive electronics, industrial equipment, and security systems and are key components for realizing electrical control and protection.

[0041] The reed of a relay is one of its core components, usually made of elastic metal material, and is responsible for implementing the switching function in the circuit. The elasticity of the reed enables the relay to respond quickly when receiving a control signal, closing or opening the circuit through mechanical actions, thereby controlling a larger current or voltage. The design and material of the reed directly affect the contact reliability, response speed, and durability of the relay. Therefore, the design, manufacturing, and maintenance of the reed are crucial for ensuring the performance of the relay.

[0042] The skew of the reed of a relay during the production process will affect the reliability of its electrical contact and the accuracy of its mechanical actions. The skewed reed may cause poor contact, unstable signal transmission, or mechanical jamming, thereby affecting the performance and service life of the entire relay. Therefore, it is necessary to correct it to ensure the flatness and alignment of the reed, so as to ensure that the relay can work stably and reliably under various working conditions.

[0043] In the related art, the correction of relay reeds is generally carried out by manually operating a correction jig, but using this correction method cannot control the correction angle of the reeds, which may lead to the problem that the requirements are still not met after correction.

[0044] To solve the above problems, the present utility model proposes a relay reed correction device, aiming to provide a relay reed correction device that can adjust the correction angle. Figures 1 to 7 FIG. 5 is a schematic structural diagram of an embodiment provided by the relay reed correction device of the present utility model.

[0045] Please refer to Figures 1 to 7 , the present utility model proposes a relay reed correction device 1000, which includes a base 1, a first driving mechanism 2 and a correction mechanism 3. The base 1 is provided with a first guide rail 11, and a first sliding seat 12 is slidably arranged on the first guide rail 11. The first driving mechanism 2 includes a motor 21 and a lead screw 22 arranged at the driving end of the motor 21. The motor 21 is arranged on the base 1, and the lead screw 22 is threadedly connected to the first sliding seat 12 and is used to drive the first sliding seat 12 to slide on the first guide rail 11. The correction mechanism 3 includes a correction head 31, and the correction head 31 is rotatably arranged on the first sliding seat 12 along the axial direction of the lead screw 22.

[0046] The technical solution of the present utility model proposes a relay reed correction device 1000 and a relay calibration device. Among them, the relay reed correction device 1000 includes a base 1, a first driving mechanism 2 and a correction mechanism 3. The base 1 is provided with a first guide rail 11, and a first sliding seat 12 is slidably arranged on the first guide rail 11. The first driving mechanism 2 includes a motor 21 and a lead screw 22 arranged at the driving end of the motor 21. The motor 21 is arranged on the base 1, and the lead screw 22 is threadedly connected to the first sliding seat 12 and is used to drive the first sliding seat 12 to slide on the first guide rail 11. The correction mechanism 3 includes a correction head 31, and the correction head 31 is used to contact the reed of the relay to be corrected. Specifically, in the correction process, first control the motor 21 to drive the lead screw 22 to rotate, thereby driving the first sliding seat 12 to slide until the correction head 31 is located directly above the relay reed and abuts against the reed. Then, control the motor 21 to drive the first sliding seat 12 to move again. At this time, due to the pressure of the correction head 31 on the relay reed, the relay reed will move together with the correction head 31. Since the reed is made of flexible metal material and has good ductility, the relay reed will be bent at a certain angle, thereby meeting the relevant standard requirements. By controlling the movement distance of the first sliding seat 12, the bending angle of the relay reed can be controlled, so as to ensure that relay reeds with various deviation angles can be corrected to meet the requirements.

[0047] To clamp the relay reed to ensure that the reed is bent and corrected, the correction head 31 is provided with a clamping groove 311 facing the base 1. Specifically, please further refer to Figure 7, the slot width of the clamping groove 311 is slightly larger than the thickness of the relay reed, so that a certain error gap can be left to prevent the claw 312 from rubbing against the relay reed when the first sliding seat 12 does not move in place, resulting in scratches on the product surface. During the correction operation, the relay reed is placed in the clamping groove 311. When the motor 21 drives the lead screw 22 to rotate, the lead screw 22 will drive the first sliding seat 12 screwed thereto to move along the first guide rail 11, so that the correction head 31 moves relative to the relay reed. At this time, the relay reed will be bent under the abutting action of the claw 312, thus realizing the correction. Further, since the two sides of the relay reed are provided with contacts for controlling the on-off of the circuit, and the contacts protrude from the side wall of the relay reed, in order to prevent the two claws 312 of the correction head 31 from interfering with the contacts, the two claws 312 are respectively provided with arc-shaped grooves 313 facing the base 1. Specifically, please further refer to Figure 7 , the arc-shaped groove 313 is used to avoid the contacts on the relay reed, so as to reduce the problems of mechanical interference and poor contact. Through the precise design of the arc-shaped groove 313, it can be ensured that the reed has enough space for flexible movement during operation, avoiding collision or friction with the contacts, thereby protecting the contacts from damage and extending the service life of the relay.

[0048] To realize the automatic contact and separation between the correction head 31 and the relay reed, the correction mechanism 3 further includes a second driving mechanism 32. The second driving mechanism 32 is arranged on the first sliding seat 12. The first driving mechanism 2 is provided with a driving end facing the correction head 31, and the driving end is provided with a wedge-shaped guiding block 33. Specifically, please further refer to Figure 3 , Figure 4 and Figure 6 , the correction head 31 is rotatably arranged on the first sliding seat 12 through a guiding arm 34. One end of the guiding arm 34 close to the wedge-shaped guiding block 33 is provided with a roller 341, and the roller 341 is used for rolling contact with the wedge-shaped guiding block 33. The correction head 31 is located at the end of the guiding arm 34 far from the roller 341. The correction head 31 has a release state and an abutting state. When the correction head 31 is in the release state, the roller 341 of the guiding arm 34 abuts against the lower plane 332 of the wedge-shaped guiding block 33. At this time, the correction head 31 is warped upward as a whole, so that it can move above the relay reed following the first sliding seat 12 without interfering with the relay reed; after the correction head 31 is located directly above the relay reed, the driving end of the second driving mechanism 32 moves forward, pushing the wedge-shaped guiding block 33 to be inserted below the roller 341. At this time, the roller 341 is lifted and abuts against the guiding inclined plane 331 of the wedge-shaped guiding block 33, and the correction head 31 moves downward until the relay reed is clamped into the clamping groove 311. At this time, the correction head 31 is in the abutting state. To install the guiding arm 34, the first sliding seat 12 extends upward to form a bracket 41, and the guiding arm 34 is rotatably connected to the bracket 41.

[0049] To enable the correction head 31 to switch from the abutting state to the released state, the correction mechanism 3 further includes a reset member 37. Specifically, please further refer to Figure 3 , the reset member 37 is preferably a tension spring. The two ends of the tension spring are respectively fixed to the first sliding seat 12 and the end of the guide arm 34 away from the roller 341. The tension spring provides a downward pulling force so that the roller 341 always abuts against the wedge-shaped guide block 33, and the position of the correction head 31 is changed by moving the wedge-shaped guide block 33.

[0050] To achieve fine adjustment of the correction head 31 approaching or departing from the fixture of the fixed relay, the relay reed correction device 1000 further includes a second sliding seat 4. Specifically, please further refer to Figure 2 and Figure 3 , the first sliding seat 12 is provided with a second guide rail 121. The second guide rail 121 extends in a direction perpendicular to the axial direction of the first guide rail 11. The second sliding seat 4 is slidably arranged on the second guide rail 121, and the correction mechanism 3 is arranged on the second sliding seat 4. Correspondingly, the first sliding seat 12 is provided with a third driving mechanism 35. The driving end of the third driving mechanism 35 is connected to the second sliding seat 4 and can push the second sliding seat 4 to move. The correction mechanism 3 is arranged on the second sliding seat 4. When the second sliding seat 4 moves relative to the relay fixture, the position of the correction head 31 relative to the relay reed can be finely adjusted. Further, the relay reed correction device 1000 further includes a limiting member 36. The limiting member 36 is arranged on the first sliding seat 12 and is located on the moving path of the third driving mechanism. The limiting member 36 can limit the movement of the third driving mechanism 35.

[0051] The present utility model also provides a relay calibration device. The relay calibration device includes the relay reed correction device 1000. The specific structure of the relay reed correction device 1000 refers to the above embodiments. Since this relay calibration device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0052] The above are only exemplary embodiments of the present utility model and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
