Description

Technical Field

[0001] This utility model relates to the field of electric cleaning machine technology, and in particular to a relay contact electric cleaning machine. Background Technology

[0002] Relay electrical cleaning involves applying voltage and current to generate an electric arc at the contacts, thereby cleaning away oxides. This method effectively removes impurities such as oxides and carbon deposits from the relay contact surface, restoring the contacts' conductivity and thus improving the relay's lifespan and stability.

[0003] Publication No. CN204130454U discloses a relay contact electric cleaning machine, comprising four parts: an operating frequency control circuit powered by a DC adjustable regulated power supply, a frequency control time relay connected in series, and the operating coil of a product relay connected in series; a group control intermediate relay with a group switching control circuit connected before the product relay; a cleaning load circuit powered by a switching power supply, with a high-power adjustable resistor and an ammeter connected in series between the power supply and the product relay contacts; a group switching control circuit connected to another time relay by a touch switch, which in turn connects to the group control intermediate relay controlling the operating frequency and the intermediate relay controlling load switching; and a product relay to be processed is fixedly placed on the main frame. The electric cleaning time can be accurately controlled.

[0004] In existing technologies, relay cleaning cannot be performed automatically, requiring manual placement of the relays, which reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where relays cannot be automatically cleaned and require manual placement of relays, thus reducing work efficiency. Therefore, this invention proposes a relay contact cleaning machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A relay contact cleaning machine, comprising:

[0008] The work plate has four support legs installed at the bottom and a groove on the top, in which a conveying mechanism is installed.

[0009] Four support rods are all fixedly installed on the top of the work plate, and the top of the four support rods is equipped with the same top plate;

[0010] The clamping electro-cleaning mechanism is installed on the top plate and is used for electro-cleaning relays.

[0011] Preferably, the conveying mechanism includes two conveying rollers, both of which are rotatably mounted in grooves. The outer sides of the two conveying rollers are connected to the same conveyor belt, which is made of rubber. A servo motor drives one conveying roller to rotate, and the other conveying roller drives the conveyor belt to move.

[0012] Preferably, a servo motor is mounted on the outer side of the work plate, and the output shaft of the servo motor is fixedly mounted to one of the two conveyor rollers.

[0013] Preferably, the clamping electric cleaning mechanism includes two linear motors, both of which are mounted on the top of the top plate. A common fixing plate is mounted on the output shafts of the two linear motors. Two clamping plates are slidably mounted on the bottom of the fixing plate, and multiple electric cleaning rods are mounted on each of the clamping plates. The electric cleaning rods are fixed to the clamping plates with screws, and their positions can be adjusted. A current and voltage controller is provided on the top of the fixing plate, and the multiple electric cleaning rods are electrically connected to the current and voltage controller. The current and voltage controller supplies power to the multiple electric cleaning rods and can adjust the working voltage and current of the electric cleaning rods.

[0014] Preferably, two cylinders are fixedly installed at the bottom of the fixed plate. The two cylinders are symmetrically arranged, and the output shafts of the two cylinders are fixedly installed with the two clamping plates. The two cylinders push the two clamping plates to move, adjust the spacing between multiple electric cleaning rods, and adapt to electric cleaning of relays of different sizes.

[0015] Preferably, two round rods are fixedly installed at the bottom of the fixing plate, and the same pressure plate is slidably installed on the outer side of the two round rods. Two round grooves are formed at the top of the pressure plate, and the two round rods are slidably connected to the inner walls of the two round grooves. A rubber strip is provided at the bottom of the pressure plate, and a spring is fixedly installed on the inner wall of the round groove. The top end of the spring is fixedly installed to the bottom end of the round rod. The two round rods push the pressure plate downward through the two springs, and the pressure plate drives the rubber strip to press the relay tightly, ensuring the stability of the electric cleaning.

[0016] The beneficial effects of the relay contact electric cleaning machine described in this utility model are as follows:

[0017] This solution places the relays on top of the conveyor belt. A servo motor drives one conveyor roller to rotate, which in turn drives the conveyor belt through another conveyor roller. The conveyor belt moves the relays, which then move to the bottom of multiple electro-cleaning bars for electro-cleaning. The conveyor belt continues to transport the relays, enabling automatic transport and improving work efficiency.

[0018] In this design, two linear motors drive a fixed plate downwards, which in turn drives two clamping plates downwards. Two round rods, through two springs, push a pressure plate downwards, which in turn drives a rubber strip to press the relay firmly, ensuring the stability of the electric cleaning process.

[0019] In this design, two clamping plates drive multiple electric cleaning rods downwards. These rods then contact the relay contacts, and a current and voltage controller energizes them to perform electric cleaning on the relays. Two cylinders push the two clamping plates to adjust the spacing between the electric cleaning rods, accommodating relays of different sizes for electric cleaning.

[0020] This invention can automatically convey materials during operation, improving work efficiency, and can adjust the spacing between multiple electric cleaning rods to accommodate relays of different sizes for electric cleaning. Attached Figure Description

[0036] Reference Figure 4 , Figure 5In this embodiment, two cylinders 12 are fixedly installed at the bottom of the fixed plate 11. The two cylinders 12 are symmetrically arranged, and the output shafts of the two cylinders 12 are fixedly installed with two clamping plates 13.
