Description

Technical Field

[0001] The present invention discloses a method for cleaning a relay, which is particularly applicable to the field of relays. The method mainly cleans the pins of the metal parts of the relay, greatly improving the working hours and reducing the cost caused by manpower. Background Art

[0002] Relays are necessary electronic components for general machines and circuits. They have control systems and controlled systems and are usually used in automatic control circuits. They are a kind of "automatic switch" that uses a smaller current to control a larger current. They play the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] Another part of the relay is mainly used to provide electrical connection with the machine and circuit board, which is generally called "contact point" or "pin". The above part is mainly made of metal, and the most worrying thing about metal is that it will oxidize after contact with the outside air and foreign matter, causing the metal surface to begin to deteriorate. When the metal part begins to oxidize and produces contact spots, it will produce impedance during contact and affect the efficiency and energy of its conduction when it is powered on. However, when the metal part of the relay begins to oxidize, the general relay manufacturer will disassemble it and perform surface treatment by electrolysis. However, the above-mentioned surface treatment method by electrolysis is too time-consuming and labor-intensive, and when the number of relays that need surface treatment is large, the electrolysis method cannot bear the load at all. Moreover, the use of a large amount of electrolyte is not only expensive, but also has some impact on the body and the environment. Summary of the invention

[0004] In order to improve the problem in the prior art that surface treatment by electrolysis is too labor-intensive and time-consuming, and that the electrolysis method also has a certain degree of impact on the body and the environment, the present invention provides an operating method for cleaning relays, which allows the industry to process a large number of relays that require surface treatment in a fast, time-saving and labor-saving manner.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A method for cleaning a relay comprises the following steps: a loading step: placing the relay on a loading table of a machine, and irradiating the relay with laser light by a laser processing head of the machine; and a surface treatment step: starting the laser processing head to operate and performing laser surface treatment on a part of the relay to be treated.

[0007] According to the above description of the present invention, its advantage is that the relay is placed on the loading table, and the laser processing of the laser processing head is used to perform laser processing on the part of the relay to be surface processed. The energy of the laser can greatly increase the speed of the surface processing operation of a large number of relays, and the laser processing of the laser processing head can make the oxidized part in the relay be removed more cleanly.

[0008] The beneficial effect of the present invention is to provide a method for the industry to process a large number of relays that require surface treatment in a fast, time-saving and labor-saving manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to clearly illustrate that the present invention can achieve the above-mentioned purpose and effect, the following is a detailed description of the features and effects of the embodiments of the present invention with the help of diagrams. Figure 1 to Figure 2 As shown, the present invention provides an operating method for cleaning relays, and the steps of the present invention include: loading step S1: placing the relay 100 on the loading table 12 of the machine 1. At this time, the relay 100 placed on the loading table 12 is mainly a semi-finished product whose internal assembly has not been completed, and only has an outer shell and internal metal parts (contacts, pins).

[0035] Continuing with the above, the surface treatment step S2 is then entered: after the relay 100 is placed on the loading platform 12, the loading platform 12 rotates to drive the relay 100 to move to the bottom of the laser processing head 13, and the laser processing head 13 performs laser surface treatment on the to-be-treated part of the relay 100. The to-be-treated part here refers to the metal part that has been oxidized. In addition, while the loading platform 12 is rotating, another relay 100 can be placed to wait for surface treatment; the cleaning step S3 is then entered: after the surface treatment step S2 is completed, the loading platform 12 rotates again, and the other relay 100 just placed on the loading platform 12 will be moved to the bottom of the laser processing head 13, and the relay 100 that has been surface treated will be Move to the bottom of the gas hood 15, the gas hood 15 moves downward and completely covers the relay 100, and the gas in the gas hood 15 is sprayed to the surface-treated part of the relay 100 to remove the surface treatment; finally, it comes to the rear-end clamping step S4: after the gas hood 15 completes the cleaning of the relay 100 in the above-mentioned cleaning step S3, the gas hood 15 will move upward to remove the cover of the relay 100, and then the material placement table 12 continues to drive the cleaned relay 100 to move to the position corresponding to the clamping arm 16 set on the machine 1, and the clamping arm 16 clamps the cleaned relay 100 and moves it to the outlet output platform 17 of the machine 1, and the transmission setting of the outlet output platform 17 is used to drive the cleaned relay 100 to be transported to the outside of the machine 1 for collection.

[0036] According to the above description, the present invention utilizes the material placement table 12 to drive the relay 100 to transfer, so that the surface treatment operation of a large number of relays 100 can be performed in the shortest time, and the use of the laser processing head 13 accelerates the processing time. Compared with the existing surface treatment using electrolyte, it is not only time-consuming but also wasteful, and the electrolyte is prone to environmental pollution. Therefore, the present invention utilizes the setting of the machine 1 to cooperate with the machinery used in each step, so that a large number of relays 100 can be more quickly processed under the surface treatment operation, and the surface of the metal part of the relay 100 that is removed can also be kept in a smooth and bright state. More importantly, removing the oxidized part can also improve the electrical conductivity between the relay 100 and other parts in the future, that is, the relay 100 is After the surface treatment of the relay 100, the molecules on the surface that do not originally belong to the metal part can be separated, thereby reducing the percentage of 50% mΩ contact resistance. The laser light excited by the laser processing head 13 used in the surface treatment of the present invention adopts low-intensity laser light, which is used to maintain the metal part of the relay 100 at a low contact resistance after cleaning, and to break down the oxide film layer of the metal part to make the conductive efficiency better. In the use of the present invention, the transfer of the relay 100 is controlled by the rotation of the material table 12 in the machine 1, and the use of the clamping arm 16, the laser processing head 13, and the gas cover 15 reduces the burden on manpower. Only one person or a small number of operators are required to complete the surface treatment of a large number of relays 100, which really achieves the effect of cost saving. Please see Figure 1 to Figure 2 shown.

[0037] After describing the main technology of the present invention, other technical features are further described below. First, please see Figure 1 , Figure 2 As shown, in order to prevent the generation of residues during the processing of the laser processing head 13 during the operation of the surface processing step S2, an air nozzle assembly 18 is further provided on the machine 1 adjacent to the laser processing head 13. The air nozzle assembly 18 includes an air jet tube 181 (two air jet tubes 181 are drawn in the figure) and a number of nozzles 182 equal to the number of the air jet tubes 181. One end of the air jet tube 181 is connected to an air source (such as an air pressure pump), and the other end of the air jet tube 181 is assembled with the nozzle 182. The nozzle 182 is arranged toward the laser processing head 13, and the nozzle 182 sprays air to the relay 100 located below the laser processing head 13 to blow away the residue during the surface processing step S2.

[0038] Continuing with the above description, in order to prevent the jet pipe 181 from running wildly due to excessive gas jetting force during jetting operation, Figure 2As shown, the material placement table 12 is further provided with a through hole 19, and the machine 1 includes a shaft frame 191, one end of the shaft frame 191 passes through the through hole 19 of the material placement table 12 and extends to the support platform 192 in the direction of the laser processing head 13, and the jet tube 181 is movably positioned on the support platform 192, and the active positioning method of the jet tube 181 can be positioned by binding with a belt, or can be tied with a rope (not shown in the figure). The active positioning method between the jet tube 181 and the support platform 192 of the present invention is not limited to the above method, which is mainly to prevent the jet tube 181 from running around; the present invention is further described. Figure 2 As shown, in order to place the relay 100 stably so that the position of the laser beam from the laser processing head 13 will not deviate after being emitted toward the relay 100, the material placement table 12 is further provided with a plurality of material placement racks 2, and each relay 100 is placed on each material placement rack 2 one by one, and the clamping arm 16 clamps the relay 100 from each material placement rack 2 to remove the relay 100. Figure 2 The drawing shows the pin positions of the relay 100 inserted into each material rack 2, and the part to be surface treated is the contact position inside the relay 100.

[0039] Another part to be mentioned is that during the cleaning step S3, the purpose of the gas hood 15 is mainly to prevent the gas from spraying and causing the residue to fly around when cleaning the residue of the relay 100, thereby affecting the surface treatment operation of other relays 100. A strong sprayer 151 is further arranged in the gas hood 15. The strong sprayer 151 sprays high pressure after the gas hood 15 completely shields the relay 100. The strong sprayer 151 sprays away the residue in the relay 100, and the gas hood 15 is used to cover the residue, so that the residue can be prevented from splashing when the spray is applied. However, in order to avoid other factors causing the residue to affect other operations, the present invention is said to be The machine 1 further includes an absorber 3 and a discharge pipe 31. One end of the discharge pipe 31 is connected to the absorber 3, and the other end of the discharge pipe 31 is connected to the gas hood 15 and communicated with the inside. When the strong sprayer 151 sprays high-pressure air to the relay 100, the absorber 3 operates and sucks air into the gas hood 15 through the discharge pipe 31, and absorbs the residue sprayed by the strong sprayer 151 in the gas hood 15 and concentrates it. By using the absorber 3, the residue can be handled in the process of the cleaning step S3, which is very convenient and time-saving for the user. The cleaning action is eliminated and the concentrated residue can be directly poured out. Please see Figure 1 , Figure 2 shown.

[0040] In summary, the operation method of the present invention is very easy for users to use. Even after the machine 1 is set up, a large number of oxidized relays 100 can be surface treated without any personal operation. After the surface treatment, the metal parts of the relays 100 can maintain a low contact resistance and good conductivity. Compared with the existing electrolyte treatment method, the present invention can spend a shorter time on the operation and obtain a large number of results, and can also reduce the use of manpower, which is obviously more practical.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
