Creation instructions () The present invention relates to welding methods, especially a method for welding covers and boards. Press, please refer to a method of welding a conventional cover and a plate body shown in the first figure. This method is to first grind off a predetermined surface on the peripheral edge of the bottom side of the cover (12). The plate body (14) is followed by an appropriate thickness of a welding material (16) (generally a metallic material) on the contact edge of the cover (12) and the plate body (14), and At the same time, the heater (18) is used to heat the surface of the welding material in a predetermined direction, so that the welding material (16) is melted after heating to produce a magnetic effect with the cover (12), so it naturally attaches to the cover 10 (12) and the The plate (14) contacts the edge. During the heating process, in order to fully adhere the welding material, an inert gas is more often introduced at the processing edge by a gas supplier, so as to avoid oxidizing and damaging the crystal molecules of the welding material. And because the above-mentioned joining method is that the welding edge is coated with the welding material at the peripheral edge of the bottom side of the cover and the plate 15, and then the heater is used to heat the welding material around. How to apply the coating and heat the welding material? The heater can be effectively used so that the welding material can evenly adhere to the processing edge. This is a technical problem that must be overcome. If the welding material is unevenly attached, it is easy to cause gaps or protrusions at the processing edge, which will cause the outer cover to join the board. quality. 20 In addition, in the process of welding between the outer cover and the plate, welding is mostly performed on the edges by dots and lines. Therefore, the welding time is relatively long and the welding cost is relatively increased. In view of this, the main purpose of the present invention is to provide a method for welding the outer cover and the plate body so that the contact edge of the outer cover and the plate body is maintained. -3- This paper size applies to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) ---: ---: ---.--- a, --- ml---------(please read the notes on the back before filling this page) Economy Printed by the Consumer Cooperatives of the Ministry of Intellectual Property Bureau 4 6 03 4 4 C7 D7 V. Creative Instructions () Smooth and smooth, and achieve a complete close effect. (Please read the precautions on the back before filling out this page.) Another purpose of this creation is to provide a method for welding the cover to the board, which can greatly reduce the welding time and achieve economic cost benefits. 5 Edge In order to achieve the above purpose, the present invention provides a method for welding an outer cover and a plate body, which mainly includes the following steps: a. First, uniformly apply a welding material with an appropriate thickness on the peripheral edge of the plate body; b. The semi-finished product of the plate body is tightly positioned and coupled to an induction coil of a high-frequency heating machine platform after being tightly positioned; c. Using the heating machine to output an oscillating current so that the periphery of the cover generates instant high heat in the induction coil 10; d. Due to the thermal effect of the outer cover, the welding material at the periphery of the plate body is melted, so that the outer cover and the plate body are completely in close contact due to the magnetic effect. The following is a detailed description of a preferred embodiment of the present invention, which will be described in detail with reference to the drawings, in which: The second diagram is a main component diagram of the welding method of the present invention. 15 The third diagram is a schematic diagram of the welding method of the present invention. First, please refer to the second and third figures. The method provided by the present invention for welding a cover to a plate mainly includes the following steps: Printing steps by the consumer co-operative society of the Intellectual Property Bureau of the Ministry of Economic Affairs a. The peripheral edge of the body (22) is evenly coated with a suitable thickness of welding material (24). In this embodiment, the board body (22) is a circuit board. At the same time, in order to facilitate soldering, the periphery of the outer cover (26) The lower edge is evenly coated with a suitable thickness of flux (28) (about 1mm in height) to make the welding process smoother, and the outer cover (26) is mainly a metal material, and the welding material (24) is based on Mainly tin alloy; Step b. Press the outer cover (26) and the semi-finished product of the plate body (22) tightly to determine the size of the paper -4- This paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) C7 D7 Fifth, the creation instructions () are placed on a high-frequency heating machine platform; (Please read the precautions on the back before filling this page) Step c. Raise the heating machine platform so that the cover (26) is coupled to the In an induction coil (29) of the heating machine, the induction coil (29) is connected to the outer The covers (26) are not in contact with each other, and the center height of the induction coil (29) is exactly the same as the joint surface of the semi-finished product when the flat 5 sets are raised; Step d. Use the heating machine to output an oscillating current to make the cover (26) The peripheral edge instantly generates high heat in the induction coil (29). At this time, because the heating part is mainly located at the peripheral edge of the cover (26), the top end surface of the cover (26) is maintained at the temperature before processing; 10 Step e Due to the thermal effect of the cover (26), the welding material (24) at the periphery of the plate (22) is melted. When a certain temperature is reached, the cover (26) and the plate (22) are completely magnetic due to the magnetic effect. adaptation. Among them, the shape, size, number of turns of the induction coil, the material of the cover, the coupling position of the heating part and the induction, etc., will affect the heating effect or the actual output power of the device. A double-turn induction coil is used, and the coupling gap between the induction coil and the heating part is mainly within 1-10mm to achieve the best efficiency. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For the heating of the outer surface of the cover which is difficult to place in the induction coil due to shape factors, or for heating non-magnetic metal materials, etc., it is possible to use 20 different shapes of magnetically conductive magnets to condense. To increase the power output of the device. Because the present invention mainly uses an induction coil to make the periphery of the outer cover generate high heat instantly, the thermal effect of the outer cover causes the welding material at the periphery of the board to melt at the same time. Welding with dots and lines not only greatly simplifies the welding time and time. This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) C7
