Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a relay contact wiping device and a relay production equipment. Background Technology

[0002] Wiping the contacts is a crucial step in relay manufacturing. During manufacturing, assembly, and storage, the contact surface is easily contaminated, forming particulate contaminant films, inorganic chemical films (such as oxides and sulfides), and organic chemical films (such as insulating or semiconductor films). These films increase the contact resistance, reducing the relay's performance and reliability.

[0003] Traditional wiping methods primarily rely on manual operation. However, manual wiping presents numerous problems: First, it easily scratches the contact surface, leading to poor contact, and also damages the coating, affecting its lifespan. Second, manual wiping is greatly affected by human factors; the operating technique is difficult to control, making it difficult to effectively remove oxide layers and dirt from the contact surface. Furthermore, manual wiping suffers from low production efficiency, high safety hazards, inconsistent wiping frequency, excessive wiping force damaging contacts, easy wear and tear on the wiping belt, and easy evaporation of the wiping solution, resulting in high consumption of defective products and high consumable costs. Currently, there is no automated equipment specifically designed for wiping relay contacts on the market. Therefore, developing an automated wiping machine that can replace manual operation, reducing labor intensity, saving manpower, and improving wiping quality and efficiency is a pressing technical problem that needs to be solved.

[0038] In relay manufacturing, traditional relay contact wiping methods primarily rely on manual operation. However, manual wiping presents several problems: First, it easily scratches the contact surface, leading to poor contact, and also damages the surface plating, affecting its lifespan; second, manual wiping is greatly affected by human factors, making it difficult to control the operation technique and effectively remove oxide layers and dirt from the contact surface; furthermore, manual wiping suffers from low production efficiency, high safety hazards, inconsistent wiping frequency, excessive wiping force damaging the contacts, easy wear of the wiping belt, and easy evaporation of the wiping solution, resulting in high consumption of defective products and high consumable costs. Currently, there is no automated equipment specifically designed for relay contact wiping on the market. Therefore, developing an automated wiping machine that can replace manual operation, reducing labor intensity, saving manpower, and improving wiping quality and efficiency is a pressing technical problem that needs to be solved.

[0039] To address the aforementioned problems, this utility model proposes a relay contact wiping device 100, aiming to provide a device that can automate relay contact wiping, thereby saving manpower and improving wiping quality. Figures 1 to 7 This is a schematic diagram of one embodiment of the relay contact wiping device 100 of this utility model.

[0040] Please refer to Figures 1 to 7This utility model proposes a relay contact wiping device 100, including a base 1, a base plate 2, a wiping mechanism 5, and a wiping belt 6. The base 1 is provided with a movable clamp seat 11 for clamping the relay contact to be wiped. The base plate 2 is provided on the base 1 and is provided with a belt feeding mechanism 3, a belt take-up mechanism, and a first motor 21. The wiping mechanism 5 includes a movable plate 51 and a wiping assembly 52. ​​The wiping assembly 52 is provided on the movable plate 51, and the movable plate 51 is movably provided on the base plate 2. The drive end of the first motor 21 is provided with an eccentric wheel 22. The movable plate 51 forms a mating groove 511. The eccentric wheel 22 abuts against the mating groove 511 to drive the movable plate 51 to reciprocate. One end of the wiping belt 6 is wound around the belt feeding mechanism 3, and the other end is wound around the belt take-up mechanism. At least a portion of the structure of the wiping belt 6 located between the belt feeding mechanism 3 and the belt take-up mechanism abuts against the side of the wiping assembly 52 facing the clamp seat 11.

[0041] The present invention provides a relay contact wiping device 100 and a relay production equipment. The relay contact wiping device 100 includes a base 1, a base plate 2, a wiping mechanism 5, and a wiping belt 6. The base 1 is provided with a movable clamp seat 11. The base plate 2 is disposed on the base 1 and perpendicular to the base 1. The base plate 2 is provided with a belt feeding mechanism 3 for conveying the wiping belt 6 and a belt taking mechanism for recycling the used wiping belt 6. The wiping mechanism 5 includes a movable plate 51 and a wiping assembly 52. ​​The movable plate 51 is movably disposed on the base plate 2. The base plate 2 is provided with a first motor 21. The eccentric wheel 22 at the drive end of the first motor 21 engages with the mating groove 511 on the movable plate 51 to drive the movable plate 51 to reciprocate relative to the base plate 2. The wiping assembly 52 is disposed on the movable plate 51 and moves in the same direction as the movable plate 51. One end of the wiping belt 6 is wound around the belt feeding mechanism 3, and the other end is wound around the belt taking mechanism. A portion of the wiping belt 6 between the two ends abuts against the wiping assembly 52. During the wiping operation, the contact workpiece to be wiped is placed on the fixture seat 11, which fixes it and sends it under the wiping assembly 52. ​​The wiping assembly 52 presses the wiping material against the contact surface and drives the wiping belt 6 to reciprocate on the contact surface, thereby effectively removing the oxide layer, dirt and contaminants on the contact surface and improving the electrical performance and service life of the relay.

[0042] To enable the movement of the fixture base 11, the base 1 is provided with a slide rail 12. For details, please refer to further documentation. Figure 7 The drive end of the third cylinder 13 is connected to the fixture seat 11 and can drive the fixture seat 11 to move on the slide rail 12, thereby realizing the loading and unloading of products.

[0043] It is understandable that the movable plate 51 drives the eccentric wheel 22 via the first motor 21, and the eccentric wheel 22 engages with the mating groove 511 to achieve drive. For details, please refer to further documentation. Figure 3To guide the movable plate 51, the base plate 2 has a guide rail (not shown in the figure) parallel to the base 1 on the side facing the movable plate 51, and the movable plate 51 is slidably mounted on this guide rail. This design allows the movable plate 51 to perform stable reciprocating motion along the guide rail. The eccentric wheel 22 driven by the first motor 21 abuts against the mating groove 511 on the movable plate 51, and the rotation of the eccentric wheel 22 drives the movable plate 51 to move precisely back and forth along the guide rail. This reciprocating motion allows the wiping assembly 52 to move evenly and stably on the relay contact surface, thereby achieving comprehensive wiping of the contact surface. The reciprocating motion of the movable plate 51 along the guide rail ensures the repeatability and consistency of the wiping process, avoiding the problems of uneven wiping or missed wiping areas that may occur during manual wiping, while improving wiping efficiency and quality, reducing the risk of increased contact resistance or surface damage caused by uneven wiping, and significantly improving the electrical performance and service life of the relay.

[0044] During the cleaning process, the clamping seat 11 moves the contact product to be cleaned to below the wiping assembly 52. ​​To control the wiping head 523 of the wiping assembly 52 to contact or disengage from the product, a sliding seat 521 is movably mounted on the movable plate 51. The drive end of the first cylinder 522 is connected to the sliding seat 521, which is used to move the sliding seat 521 closer to or away from the clamping seat 11. The wiping head 523 is mounted on the sliding seat 521. For details, please refer to further documentation. Figure 6 When wiping is required, the first cylinder 522 extends, pushing the sliding seat 521 forward, causing the wiping head 523 to contact the contact structure 200 for wiping. After wiping, the cylinder retracts, causing the sliding seat 521 to move backward, disengaging the wiping head 523 from the contact structure 200. This design precisely controls the contact pressure between the wiping head 523 and the contact structure 200 through the extension and retraction of the first cylinder 522, preventing damage to the contacts due to excessive pressure while ensuring wiping effectiveness. The movable design of the sliding seat 521 improves wiping flexibility, allowing it to adapt to contacts of different sizes and shapes. Furthermore, this automated operation reduces manual intervention, improves wiping efficiency and consistency, and reduces labor intensity.

[0045] To further optimize the cleaning effect, in one embodiment of this application, the relay contact wiping device 100 further includes a liquid injection mechanism 7, which includes a liquid storage box 71, a liquid injection valve 72, and a contact portion 73. For details, please refer to further details. Figure 5Its function is to add cleaning fluid to the wiping belt 6 during the wiping process. The cleaning fluid softens and dissolves the oxide layer, dirt, and contaminants on the contact surface, thereby improving the wiping effect, ensuring the contact surface is clean, reducing contact resistance, and improving the electrical performance of the relay. In practice, the cleaning fluid in the reservoir is controlled by the filling valve 72 to regulate the flow rate and delivery time, and then reaches the contact part 73 (usually a sponge) through the delivery pipe 74. The contact part 73 comes into contact with the wiping belt 6, evenly spreading the cleaning fluid onto the wiping belt 6, thereby cleaning the contacts. This design improves the consistency of the wiping process by automatically controlling the amount and timing of the cleaning fluid, reducing manual intervention and labor intensity. At the same time, the lubricating effect of the cleaning fluid also reduces the friction between the wiping belt contact area 61 and the contact structure 200, extending the service life.

[0046] To prevent cleaning fluid from dripping from the contact part 73 and contaminating the surface of the base 1, the base 1 is equipped with a drip tray 14. For details, please refer to further documentation. Figure 1 This ensures a clean and tidy working environment, avoiding the risk of slipping and other safety hazards caused by dripping cleaning fluid; secondly, it reduces the waste of cleaning fluid, as centralized collection facilitates subsequent recycling or treatment; it also reduces the risk of equipment corrosion caused by cleaning fluid residue, extends the service life of the equipment, and ensures the smooth progress of the wiping process, improving the reliability and maintenance efficiency of the equipment.

[0047] To prevent relative movement between the wiping belt 6 and the wiping head 523 during wiping, which could result in poor cleaning of the contact points, a clamping mechanism 8 is provided on the movable plate 51. For details, please refer to further documentation. Figure 6 The clamping mechanism 8 effectively locks the wiping belt 6, ensuring the stability and consistency of the wiping action. Through the extension and retraction of the second cylinder 82, the abutment member 83 can tightly abut or disengage the wiping belt 6 relative to the abutment roller 81, achieving clamping and releasing of the wiping belt 6. The advantages of this design are: firstly, it prevents the wiping belt 6 from shifting or loosening due to external force or vibration during wiping, ensuring the uniformity and reliability of the wiping effect; secondly, the clamping mechanism 8 can dynamically adjust according to the tension of the wiping belt 6 and the movement state of the wiping head 523, further improving the stability of the wiping process; this automated clamping and releasing mechanism reduces manual intervention, improves wiping efficiency and automation, reduces labor intensity, and also helps extend the service life of the wiping belt 6.

[0048] To ensure that the wiping belt 6 is at the appropriate tension, in one embodiment of this application, a tensioning wheel 23 is also provided. For details, please refer to further reading. Figure 2The position and function of the tensioning wheel 23 vary depending on the installation location. When the tensioning wheel 23 is located on the base plate 2, it is mainly used to fix the path of the wiping belt 6, ensuring that the wiping belt 6 is stable and has uniform tension during transmission, preventing slack or deviation. If it is located on the movable plate 51, it can dynamically adjust the tension of the wiping belt 6 as the movable plate 51 moves, adapting to changes during the wiping process and ensuring the wiping effect. Setting the tensioning wheel 23 on both the base plate 2 and the movable plate 51 combines the advantages of both, further improving the stability and adaptability of wiping. Setting the tensioning wheel 23 can improve wiping stability, dynamically adjust the tension to adapt to the wiping process, extend the service life of the wiping belt 6, and ensure uniform contact between the wiping head 523 and the contact points, thereby improving the wiping effect and reducing the contact resistance of the contact surface.

[0049] In this relay contact wiping device 100, both tape feeding and tape retraction are automated. For details, please refer to further documentation. Figure 2 The tape feeding and take-up processes are as follows: The tape feeding mechanism 3 includes a first take-up reel 31 and a second motor 32. The first take-up reel 31 is mounted on the base plate 2 and is used to wind the wiping tape 6. The drive end of the second motor 32 is connected to the first take-up reel 31. The rotation of the motor drives the take-up reel to rotate, thereby releasing the wiping tape 6 from the take-up reel. The tape take-up mechanism includes a second take-up reel 4 and a third motor 42. The second take-up reel 4 is also mounted on the base plate 2, located on one side of the first take-up reel 31, and is used to wind the used wiping tape 6. The drive end of the third motor 42 is connected to the second take-up reel 4. The rotation of the motor drives the take-up reel to rotate, winding the wiping tape 6. With this design, the tape feeding and take-up processes can be automated, ensuring that the wiping tape 6 maintains appropriate tension during the wiping process, preventing the wiping tape 6 from loosening or breaking, thereby improving the wiping effect and the stability of equipment operation.
