Description

[Technical field]

[0001] The present invention relates to a method for cleaning a relay, and more particularly to a method for cleaning a relay, which is applicable to the field of relays and mainly involves cleaning the leads having metal parts of the relay, thereby significantly increasing the working time and reducing the labor cost. [Background technology]

[0002] A relay is an electronic component required for general machines and circuits, which has a controlling system and a controlled system, and is usually applied to automatic control circuits. It is an "automatic switch" that controls a large current with a small current, and is responsible for automatic adjustment, safety protection, circuit conversion and other functions in the circuit.

[0003] In addition, relays have parts for electrically connecting with machines and circuit boards, which are generally called "contacts" or "leads." The above parts are mainly made of metal, but the most worrisome thing about metal is that it oxidizes when it comes into contact with the outside air or foreign objects, and the metal surface changes. When the metal parts start to oxidize and contact spots appear, resistance occurs at the time of contact, which affects the conductivity efficiency and energy when electricity is passed through. Summary of the Invention [Problem to be solved by the invention]

[0004] However, general relay manufacturers have found that when the metal parts of relays start to oxidize, they remove them and perform surface treatment using an electrolytic method. The above-mentioned electrolytic surface treatment requires time and effort, and when there are a large number of relays that need surface treatment, the electrolytic method cannot be used. In addition, the large amount of electrolyte used increases the cost and has a large impact on the body and the environment.

[0005] Therefore, the relevant companies have been pondering over how to improve the process, and when performing surface treatment on a large number of relays, it is important to consider how to perform the treatment quickly while also taking into account the protection of the body and the environment.

[0006] The present invention has been made by the inventors through their intensive research in consideration of the above problems, and its purpose is to provide a method for cleaning relays. In other words, the present invention enables a company to process a large number of relays that require surface treatment in a fast, time-saving and labor-saving manner, thereby improving the situation where the surface treatment by electrolysis in the prior art is time-consuming and labor-intensive, and the electrolysis method also has a certain degree of impact on the body and the environment. [Means for solving the problem]

[0007] In order to achieve the above objects and advantages, the present invention provides a method for cleaning a relay. The method for cleaning a relay according to the present invention includes a loading step in which a relay is placed on a mounting table of a machine and a laser processing head of the machine irradiates laser light toward the relay, and a surface treatment step in which the laser processing head is started to operate and a laser surface treatment is performed on the portion of the relay to be processed. Effect of the Invention

[0008] As described above, the present invention has the following advantages. The relay is placed on the placement table, and the laser processing head is used to process the relay, and the laser processing is performed on the areas of the relay that require surface treatment. By using the energy of the laser, the speed of the surface treatment work for a large number of relays is greatly improved, and by processing with the laser of the laser processing head, the cleaning of the oxidized areas inside the relay is more hygienic.

[0009] Other objects, configurations and effects of the present invention will become apparent from the following detailed description of the preferred embodiments of the present invention. [Brief description of the drawings]

[0010] [Figure 1] 1 is a flow chart illustrating a method for cleaning a relay according to an embodiment of the present invention. [Diagram 2] 4 is a schematic diagram showing an operation method for cleaning a relay according to an embodiment of the present invention; FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0012] Hereinafter, a method for cleaning a relay according to the present invention will be described with reference to Figs.

[0013] First, as shown in FIG. 1 and FIG. 2, the method for cleaning a relay according to the present invention mainly includes the following steps:

[0014] <Loading step S1> The relay 100 is placed on the placement table 12 of the machine 1. At this time, the relay 100 placed on the placement table 12 is mainly a semi-finished product with the internal assembly not yet completed, and only has an outer case and internal metal parts (contacts, pins).

[0015] <Surface treatment step S2> After the relay 100 is placed on the placement table 12, the placement table 12 rotates to move the relay 100 below the laser processing head 13, and the laser processing head 13 performs laser surface treatment on the part of the relay 100 to be treated. The part to be treated refers to an oxidized metal part, and while the placement table 12 rotates, other relays 100 to be surface treated are successively placed on the placement table 12.

[0016] <Cleaning step S3> After completion of the above-mentioned surface treatment step S2, the mounting table 12 rotates, and the other relays 100 mounted on the mounting table 12 are moved to below the laser processing head 13, and the relays 100 for which surface treatment has been completed are moved below the gas mask 15, and as the gas mask 15 moves downward, it completely covers the relays 100, and the surface treatment is performed by spraying gas onto the portion of the relay 100 to be surface-treated within the gas mask 15.

[0017] <Rear end clamping step S4> After the cleaning of the relay 100 by the gas mask 15 in the cleaning step S3 is completed, the gas mask 15 moves upward to uncover the relay 100, and then the placement table 12 continuously moves the cleaned relay 100 to a position corresponding to the clamping arm 16 installed in the machine 1, and the clamping arm 16 clamps the cleaned relay 100 and moves it to the exit export platform 17 of the machine 1, and the exit export platform 17 is installed in a transmitting manner to collect the cleaned relay 100 in a linked manner so as to transport it outside the machine 1.

[0018] As described above, the present invention performs the surface treatment of a large number of relays 100 in the shortest time by linking the transfer of the relays 100 by the placement table 12, and accelerates the treatment by using the laser processing head 13. The conventional surface treatment using an electrolyte solution is not only time-consuming, but also costly, and the electrolyte solution is prone to cause environmental pollution problems. Therefore, the present invention installs the machine 1 in combination with the machines used in each step to further speed up the surface treatment operation of a large number of relays 100, and keeps the surface of the metal parts of the relays 100 to be cleaned in a smooth state. More importantly, the removal of the oxidized parts increases the electrical conductivity between the relays and other elements even after 100 days, that is, after the surface treatment of the relays 100 is performed, molecules that do not originally belong to the metal parts are separated from the surface, and the contact resistance is reduced by 50% mΩ. In the present invention, a low-intensity laser beam is used for the laser beam excited by the laser processing head 13 used for surface treatment, and its purpose is to maintain low contact resistance even after cleaning the metal parts in the relay 100, and to further improve the conductive efficiency by penetrating the oxide film layer of the metal parts. In addition, by using the present invention, the transfer of the relay 100 is controlled by the rotation of the mounting table 12 in the machine 1, and the clamping arm 16, the laser processing head 13, and the gas mask 15 are used to reduce the human burden, and one or a few workers can carry out the surface treatment work of a large number of relays 100, which certainly achieves the effect of saving costs (see Figures 1 and 2).

[0019] After describing the main technology of the present invention, other technical features will be described in detail. First, as shown in Figures 1 and 2, in order to prevent residual scum from being generated by the laser processing head 13 during the operation process of the surface treatment step S2, the machine 1 is provided with an air nozzle assembly member 18 adjacent to the laser processing head 13, and the air nozzle assembly member 18 is provided with a spurt pipe 181 (two spurt pipes 181 are shown in the figure) and a number of nozzles 182 equal to the number of the spurt pipes 181, one end of the spurt pipe 181 is connected to a gas source (e.g., an air pump), and the other end of the spurt pipe 181 is mutually assembled to the nozzle 182. The installation direction of the nozzle 182 is directed toward the laser processing head 13, and in the surface treatment step S2, the nozzle 182 spurts air toward the relay 100 located below the laser processing head 13 to blow away residual scum.

[0020] Next, in order to prevent the blowpipe 181 from blowing out in a disorderly manner due to the excessive gas blowing force when the blowpipe 181 blows out, the mounting table 12 is further provided with a through hole 19 (see FIG. 2). The machine 1 is equipped with a pedestal 191, one end of which passes through the through hole 19 of the mounting table 12 and a support platform 192 is extended toward the laser processing head 13, and the blowpipe 181 is movably positioned on the support platform 192. In addition, the movable positioning method of the blowpipe 181 may be positioned by tying it with a cable tie or tying it with a rope (not shown), and the present invention does not limit the movable positioning method between the blowpipe 181 and the support platform 192 to the above method, and mainly prevents the blowpipe 181 from blowing out in a disorderly manner. 2, in order to stably mount the relay 100 and prevent the position from shifting after the laser of the laser processing head 13 is emitted toward the relay 100, a plurality of mounting shelves 2 are further installed on the mounting table 12, and each relay 100 is mounted on each mounting shelf 2 one by one. The clamping arm 16 clamps and releases the relay 100 from each mounting shelf 2, and as shown in FIG. 2, the lead position of the relay 100 is inserted into each mounting shelf 2, and the part to be surface treated is located at the contact position inside the relay 100.

[0021] Incidentally, in the process of the cleaning step S3, the gas mask 15 is mainly used for cleaning the residual scum from the relay 100. In order to prevent the residual scum from scattering due to the gas injection and affecting the surface treatment work of other relays 100, a powerful injector 151 is further installed in the gas mask 15. The powerful injector 151 performs high-pressure injection after the gas mask 15 completely covers the relay 100. The powerful injector 151 blows away the residual scum remaining in the relay 100 and combines with the gas mask 15 to cover it, thereby preventing the residual scum from scattering due to the injection. However, in order to prevent the residual scum from affecting other work due to other factors, the machine 1 of the present invention further includes a suction device 3 and an exhaust pipe 31. One end of the exhaust pipe 31 is connected to the suction device 3, and the other end of the exhaust pipe 31 is connected to the gas mask 15 and communicates with the inside. In addition, the powerful injector 151 sprays high pressure air onto the relay 100, and at the same time, the suction device 3 operates to suck air into the gas mask 15 through the exhaust pipe 31, and collects the residue blown away by the powerful injector 151 from inside the gas mask 15. By using the suction device 3, the residue can be smoothly disposed of during the cleaning step S3. For the user, this can save a lot of time and effort, and the cleaning operation can be omitted, and the collected residue can be directly disposed of (see Figures 1 and 2).

[0022] In conclusion, the operation method of the present invention is very easy for users, and after completing the setting of the machine 1, the surface treatment can be carried out on a large number of oxidized relays 100 without any manual operation, and the metal parts of the relays 100 after the surface treatment have low contact resistance and good conductivity. Compared with the conventional electrolyte treatment method, the present invention requires less cost and time, achieves better results, and reduces the labor required for use, making it highly practical.

Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.
