Description

Technical Field

[0001] This disclosure relates to an induction heating welding apparatus. Background Technology

[0002] The content described in this section is merely for providing background information on this utility model and does not constitute prior art.

[0003] Induction heating refers to the method of heating objects using electromagnetic induction.

[0004] Existing high-frequency induction heaters consist of a coil. If a high-frequency current flows in the coil, an electromagnetic field will be formed around the coil. The metal, as the heated object based on the electromagnetic field, will generate eddy currents within it, thus heating the metal.

[0005] Welding based on existing high-frequency induction heaters is limited in that it can only be effectively performed when the target object has a specific shape and size. Furthermore, the coil shape of existing high-frequency induction heaters is fixed; therefore, depending on the size or shape of the target object, welding may sometimes be impossible.

[0006] Existing induction heaters sometimes fail to uniformly regulate the overall temperature of the base metal during welding, for example, when the base metal has a complex shape or uneven thickness. When different parts of the base metal are heated to different temperatures, the weld quality deteriorates. For contact induction heating, because welding requires physical contact with the target material, there is a possibility of reduced contact surface quality. Utility Model Content

[0065] Reference Figures 1 to 5 The induction welding apparatus 100 provided in this disclosure can generate heat on a welding target object using induction heating. The welding target object refers to the object that serves as the welding target. Welding is performed on the welding target object based on the heat generated by induction heating.

[0066] The induction heating welding apparatus 100 provided in this disclosure can perform welding without contact with the target object. When welding is performed without contact with the target object, the welding behavior is not limited by the shape or size of the target object. When welding is performed without contact with the target object, there is no possibility of degrading the surface quality of the target object.

[0067] The induction heating welding apparatus 100 may include all or part of a vacuum chamber 110, a first shelf 130, a second shelf 150, a pair of rotation units 170, a plurality of height detection units 183, and a plurality of temperature detection units (not shown).

[0068] Vacuum chamber 110 provides the internal space for welding. By maintaining a vacuum state within its internal space, vacuum chamber 110 effectively reduces voids that may occur during welding. Reduced voids lead to improved weld quality.

[0069] The vacuum chamber 110 has a predetermined height. In this specification, the height direction refers to the z-axis direction illustrated in the accompanying drawings. The z-axis direction includes both (+) and (-) directions. The horizontal direction refers to the x-axis direction. The x-axis direction also includes both (+) and (-) directions.

[0070] When welding is performed in a vacuum state using the vacuum chamber 110, oxygen can be isolated, preventing the target object from being oxidized. By isolating impurities and moisture suspended in the atmosphere, the welding quality is improved.

[0071] The vacuum chamber 110 may include a door 111. The door 111 can open or close one side of the vacuum chamber 110. According to one embodiment, after the induction heating welding apparatus 100 completely closes the vacuum chamber 110 using the door 111, a vacuum can be formed in the internal space. According to one embodiment, a second shelf 150 extending into the inside of the vacuum chamber 110 may be attached to one side of the door 111. The size, shape, position, etc., of the door 111 are not limited by the figures shown.

[0072] The vacuum chamber 110 may include an exhaust unit 112. The exhaust unit 112 can be used to create a vacuum inside the vacuum chamber 110. The exhaust unit 112 can supply air into the vacuum chamber 110 to cool the welding heat generated in the base material 180, which will be described later.

[0073] The inner side of the vacuum chamber 110 may be provided with a first shelf 130, a second shelf 150, a pair of rotating parts 170, multiple height detection parts 183 and multiple temperature detection parts, etc.

[0074] The first shelf 130 is used to fix the welding target, i.e., the base metal 180. According to one embodiment, the first shelf 130 may be configured to fix the first base metal 180A and the second base metal 180B on one side and the other side. For example, the first base metal 180A may be fixed on the top of the first shelf 130, and the second base metal 180B may be fixed on the bottom of the first shelf 130.

[0075] According to one embodiment, the first base material 180A and the second base material 180B can be joined together by an induction heating welding device 100.

[0076] When the cavity door 111 is closed, the first shelf 130 can be located inside the vacuum chamber 110. When the cavity door 111 is opened, the first shelf 130 can be exposed to the outside of the vacuum chamber 110. When the first shelf 130 is in the exposed state, the base material 180 can be fixed to the first shelf 130.

[0077] The first shelf 130 is configured to move along a first axis direction perpendicular to the height direction. The first axis direction is equivalent to the horizontal direction. The first shelf 130 moves along the first axis direction and forms a first movement path. The first shelf 130 can move along the first axis direction during welding. When the first shelf 130 moves, the magnitude and direction of the electromagnetic field acting on the base material 180 will change. The induction heating welding apparatus 100 can adjust the heat generated at each part of the base material 180 by moving the first shelf 130. The induction heating welding apparatus 100 can uniformly adjust the temperature of the base material 180 by moving the first shelf 130. For example, when welding base materials 180 with different thicknesses at different locations, in order to generate more heat in the thicker parts of the base material 180, the position of the first shelf 130 and / or the position of the base material 180 can be adjusted. In order to generate more heat in the thicker parts, the moving speed of the first shelf 130 can be adjusted.

[0078] According to one embodiment, the first shelf 130 may be coupled to a first rail 151. The first shelf 130 may be configured to move along the first rail 151. According to one embodiment, the first rail 151 may be located at the lower part of the first shelf 130.

[0079] The second shelf 150 may be arranged below the first shelf 130. According to one embodiment, the second shelf 150 may be arranged parallel to the first shelf 130. According to another embodiment, the second shelf 150 may extend along a first axis.

[0080] According to one embodiment, the second shelf 150 may be attached to one side of the cavity door 111. In this case, the second shelf 150 may be formed extending from one side of the cavity door 111 toward the inside of the vacuum cavity 110.

[0081] A first guide rail 151 may be attached to one side of a second shelf 150. According to one embodiment, the first guide rail 151 may extend along a first axis. According to one embodiment, there may be a pair of first guide rails 151. According to one embodiment, the first guide rail 151 may engage with a first shelf 130 and guide the first shelf 130 to move.

[0082] A sliding unit 152 is attached to one side of the second shelf 150. For example, the sliding unit 152 may be attached to the underside of the second shelf 150. According to one embodiment, there may be a pair of sliding units 152. The sliding units 152 may extend along a first axis. The sliding units 152 may be coupled with a sliding guide 153. As the sliding units 152 move, the second shelf 150 coupled with the sliding units 152 also moves together. The sliding units 152 may move in the first axis direction. As the sliding units 152 move, the cavity door 111 may close the vacuum chamber 110.

[0083] According to one embodiment, the sliding guide portion 153 may be located at the lower part of the sliding portion 152. The sliding guide portion 153 may engage with the sliding portion 152 and guide the sliding portion 152 to move. When there is a pair of sliding portions 152, there may also be a pair of sliding guide portions 153 to correspond to the sliding portions 152.

[0084] The sliding guide portion 153 may include multiple guide members 154, multiple support members 155, etc. The multiple guide members 154 are directly coupled to the sliding portion 152. The multiple guide members 154 may be arranged at predetermined intervals along a first axis. The multiple guide members 154 guide the sliding portion 152 to move.

[0085] Multiple support members 155 support multiple guide members 154. According to one embodiment, the multiple support members 155 can support the underside of each of the multiple guide members 154. According to one embodiment, one side of the multiple support members 155 can be attached to one side of the vacuum cavity 110.

[0086] The induction heating welding apparatus 100 may include a horizontal adjustment motor 131. The horizontal adjustment motor 131 provides power for moving a first shelf 130. According to one embodiment, during welding, the first shelf 130 can move along a first guide rail 151 based on the power of the horizontal adjustment motor 131. To ensure uniform temperature of the base material 180, the horizontal adjustment motor 131 can adjust the position of the first shelf 130. To ensure uniform temperature of the base material 180, the horizontal adjustment motor 131 can adjust the moving speed of the first shelf 130.

[0087] The induction heating welding apparatus 100 may include a first power transfer unit 132 and a horizontal shaft 133. The first power transfer unit 132 transmits power from a horizontal adjustment motor 131 to the horizontal shaft 133. According to one embodiment, the first power transfer unit 132 may include a pulley and a belt.

[0088] The horizontal shaft 133 is configured to drive the first shelf 130 toward the first axis direction when the horizontal adjustment motor 131 is driven. According to one embodiment, the horizontal shaft 133 may extend elongatedly along the first axis direction. According to one embodiment, the horizontal shaft 133 is located on one side of the first shelf 130.

[0089] A pair of rotating parts 170 utilize magnets to generate an electromagnetic field. The rotation of the pair of rotating parts 170 alters the electromagnetic field formed inside the vacuum chamber 110. If the electromagnetic field changes based on the rotation of the pair of rotating parts 170, heat will be generated on the target object to be welded. The pair of rotating parts 170 can alter the electromagnetic field and perform welding without contacting the target object.

[0090] As described above, the first shelf 130 can form a first movement path. A pair of rotating parts 170 can be arranged spaced apart from each other along the height direction, with a first movement path between them. As shown in the figure, only a portion of the pair of rotating parts 170 is located inside the vacuum cavity 110. The position of the pair of rotating parts 170 is not limited by the figures shown. For example, the figures illustrate a portion of the pair of rotating parts 170 located inside the vacuum cavity 110, but the pair of rotating parts 170 can also be entirely located inside the vacuum cavity 110.

[0091] A pair of rotating portions 170 may be formed extending along the height direction. The pair of rotating portions 170 may be divided into a first rotating portion 170A and a second rotating portion 170B. According to one embodiment, the first rotating portion 170A may penetrate one side of the vacuum cavity 110, and the second rotating portion 170B may penetrate the other side of the vacuum cavity 110.

[0092] A pair of rotating parts 170 may each include a magnet unit 171 for generating an electromagnetic field at one end. According to one embodiment, the magnet unit 171 may include magnets. According to another embodiment, the magnet unit 171 may include a plurality of N-pole magnets and a plurality of S-pole magnets arranged in a predetermined pattern. In this case, there may be two N-pole magnets and two S-pole magnets. In this case, the N-pole magnets and S-pole magnets may be arranged alternately. At this time, the N-pole magnets and S-pole magnets may be arranged spaced apart from each other along a virtual circumference. According to one embodiment, the magnet included in the magnet unit 171 may be a magnetic monopole. A magnetic monopole has only one electromagnetic field. That is, it may be a magnet having either an N-pole or an S-pole.

[0093] The electromagnetic field generated by the magnet 171 is changed by the rotation of the rotation motor 172. The change in the electromagnetic field generates heat in the base material 180.

[0094] The magnets 171 are a pair, arranged spaced apart from each other and having a first path of movement between them. In order to generate heat on the base material 180, the pair of magnets 171 are configured as a rotatable structure to change the electromagnetic field formed inside the vacuum cavity 110.

[0095] The arrangement of the pair of rotating parts 170 and magnet parts 171 is not limited to that shown in the figures. That is, unlike that shown in the figures, the pair of rotating parts 170 and magnet parts 171 can also be arranged along the horizontal direction of the vacuum chamber 110. In this case, the first shelf 130 is configured to move in a direction parallel to the height direction of the vacuum chamber 110.

[0096] A pair of rotating parts 170 can each be positioned along a first vertical line (R, parallel to the height direction) Figure 5 ) is used as the axis of rotation for rotation.

[0097] The other end of each pair of rotating parts 170 may include a rotary motor 172 for rotation. Each pair of rotating parts 170 may rotate based on the rotary motor 172 to change the electromagnetic field formed inside the vacuum chamber 110, thereby generating heat in the base material 180.

[0098] The rotary motor 172 can adjust the rotational speed of a pair of rotating parts 170. Based on the rotational speed of the pair of rotating parts 170, the temperature of the base material 180 and the heat generated on the base material 180 can be adjusted. For example, as the rotational speed of the rotating parts 170 increases, the electromagnetic field changes more rapidly, thereby increasing the heat generated on the base material 180 per unit time. To uniformly adjust the overall temperature of the base material 180, the induction heating welding apparatus 100 can adjust the rotational speed of the rotary motor 172 in real time.

[0099] A pair of rotating parts 170 are each configured to be height-adjustable along the height direction, thereby adjusting the distance between them and the base material 180. According to one embodiment, each pair of rotating parts 170 may include a height adjustment unit 173 for adjusting the height. The height adjustment unit 173 may be arranged on one side of each pair of rotating parts 170.

[0100] According to one embodiment, one side of the height adjustment section 173 may include a height adjustment rail 174 extending along the height direction. The height adjustment rail 174 guides the movement of each of a pair of rotating sections 170. The height adjustment rail 174 may be configured as a pair corresponding to the first rotating section 170A and the second rotating section 170B.

[0101] According to one embodiment, one side of the height adjustment unit 173 may include a height adjustment motor 175. The height of the rotating unit 170 can be adjusted based on the drive of the height adjustment motor 175.

[0102] According to one embodiment, the height adjustment unit 173 may include a second power transfer unit 176 and a vertical shaft 177. The second power transfer unit 176 transmits power to the vertical shaft 177 via a height adjustment motor 175. According to one embodiment, the second power transfer unit 176 may include pulleys and a belt.

[0103] When the height adjustment motor 175 rotates, the vertical shaft 177 receives power transmitted by the second power transmission unit 176 and changes the height of each rotating part 170A, 170B. In this case, each rotating part 170A, 170B in the pair of rotating parts 170 moves with the height adjustment guide rail 174.

[0104] According to one embodiment, the vertical axis 177 may be formed extending along the height direction. According to one embodiment, the vertical axis 177 may be located between a pair of height adjustment rails 174.

[0105] The induction heating welding apparatus 100 provided in this disclosure can also drive only one of the pair of rotating parts 170. For example, when welding, only the first rotating part 170A can be rotated. The height of only the first rotating part 170A can also be adjusted. Alternatively, the first rotating part 170A can be driven but only the second rotating part 170B can be driven.

[0106] Multiple height detection units 183 are configured to detect the height of the base material 180. According to one embodiment, the induction heating welding apparatus 100 can adjust the height of each of a pair of rotating parts 170 based on the height of the base material 180. Specifically, the height adjustment motor 175 can be configured to adjust the height of each of the pair of rotating parts 170 based on the height of the base material 180 detected by the height detection units 183.

[0107] The base material 180 has thick and thin sections, and high and low sections. Multiple height detection units 183 can detect the height of each section of the base material 180. The induction heating welding apparatus 100 can be controlled to increase the heat generated on the base material 180 as its thickness increases. This is because a thicker base material 180 requires more heat to raise its temperature. For example, to increase the heat generated on the base material 180, the induction heating welding apparatus 100 can make the rotary motor 172 rotate faster, or arrange a pair of rotating parts 170 closer to the base material 180. This is because the closer the rotating parts 170 are to the base material 180, the more heat is generated on the base material 180 per unit time.

[0108] The induction heating welding device 100 can adjust the heat generated on the base material 180 per unit time by changing the speed of the horizontal adjustment motor 131.

[0109] According to one embodiment, a plurality of height detection units 183 may be arranged at intervals along the height direction. According to another embodiment, the plurality of height detection units 183 may be arranged pointing towards a first movement path, thereby enabling the detection of the height of the base material 180.

[0110] According to one embodiment, the first height detection unit 183A is configured to detect the height of the first base material 180A, and the second height detection unit 183B is configured to detect the height of the second base material 180B.

[0111] Multiple temperature detection units are configured to detect the temperature of the base material 180. These multiple temperature detection units can detect the temperature of various portions of the base material 180. According to one embodiment, the multiple temperature detection units can be arranged close to the base material 180. According to one embodiment, the multiple temperature detection units can be individually coupled to the base material 180 before welding. According to one embodiment, during welding, the multiple temperature detection units can detect the temperature of the base material 180 in real time.

[0112] According to one embodiment, the moving speed of the first shelf 130 can be adjusted based on the temperature of the base material 180 detected by multiple temperature detection units. The first shelf 130 can move continuously during the welding process. The induction heating welding apparatus 100 provided in this disclosure can adjust the moving speed of the first shelf 130 in real time in order to uniformly adjust the overall temperature of the base material 180 during the welding process.

[0113] According to one embodiment, the rotation speed of each of the pair of rotating parts 170 can be adjusted based on the temperature of the base material 180 detected by multiple temperature sensing units. The pair of rotating parts 170 can rotate continuously during the welding process. In order to uniformly adjust the overall temperature of the base material 180, the rotation speed of each of the pair of rotating parts 170 can be adjusted in real time.

[0114] According to one embodiment, the height of each of the pair of rotating parts 170 can be adjusted based on the temperature of the base material 180 detected by multiple temperature sensing units. The height of each of the pair of rotating parts 170 can be continuously adjusted during welding. To uniformly adjust the overall temperature of the base material 180, the height of each of the pair of rotating parts 170 can be adjusted in real time. When the temperature of the base material 180 is uniformly adjusted overall, it has the advantage of improving welding quality.

[0115] The control method of the induction heating welding apparatus 100 of this disclosure will now be described. The induction heating welding apparatus 100 provided by this disclosure creates a vacuum inside the vacuum chamber 110 by venting the air inside the vacuum chamber 110. Welding performed in a vacuum state minimizes porosity and improves welding quality.

[0116] The induction heating welding apparatus 100 utilizes multiple height detection units 183 to detect the height of the base material 180 fixed to the first shelf 130. Based on the height of the base material 180, the induction heating welding apparatus 100 can adjust the position of the first shelf 130, the moving speed of the first shelf 130, the rotational speed of the pair of rotating parts 170, and the height of the pair of rotating parts 170 to different values. As described above, the induction heating welding apparatus 100 provided in this disclosure can independently adjust the position of the first shelf 130, the moving speed of the first shelf 130, the rotational speed of the pair of rotating parts 170, and the height of the pair of rotating parts 170, thus enabling welding regardless of the shape, size, or type of the base material 180.

[0117] The induction heating welding apparatus 100 can adjust the height of each of the pair of rotating parts 170 based on the detected height of the base material 180. In this case, the height of each of the pair of rotating parts 170 can be adjusted independently. The closer the pair of rotating parts 170 are to the base material 180, the more heat is generated on the base material 180 per unit time.

[0118] The induction heating welding apparatus 100 allows a pair of rotating parts 170 to rotate independently. In this case, the rotational speed of each of the pair of rotating parts 170 can be adjusted individually. As the rotational speed of the pair of rotating parts 170 increases, the heat generated on the base material 180 per unit time increases. If the pair of rotating parts 170 rotate, the electromagnetic field formed inside the vacuum chamber 110 changes, thereby generating heat in the base material 180.

[0119] The induction heating welding apparatus 100 can perform welding while moving the first shelf 130 along the first moving path. When welding is performed while moving the first shelf 130, the induction heating welding apparatus 100 provided in this disclosure can adjust the height of each of the pair of rotating parts 170, the rotation speed of each of the pair of rotating parts 170, and the moving speed of the first shelf 130 in real time based on the temperature change of the base material 180 being welded.

[0120] The induction heating welding apparatus 100 cools the heat generated on the base material 180 by supplying air into the vacuum chamber 110. The air cools the weld joint or weld components, allowing them to harden and solidify.

[0121] The induction heating welding apparatus 100 provided in this disclosure can improve welding quality by uniformly adjusting the temperature of the base material 180 during the welding process. Different parts of the base material 180 can have different temperatures during welding. The induction heating welding apparatus 100 provided in this disclosure can generate more energy from insufficiently heated parts by controlling a pair of rotating parts 170 and / or a first shelf 130.

[0122] The induction heating welding apparatus 100 provided in this disclosure has significant advantages over existing induction heaters in terms of setting heating conditions. For example, existing induction heaters have a fixed coil shape, which makes it impossible to weld based on the size or shape of the target object, or results in a decrease in welding quality. They also have the problem of not being able to arbitrarily set heating conditions to suit the welding purpose. That is, existing induction heaters can only weld objects of specific shapes or sizes, which is a limitation. Unlike existing induction heaters, the induction heating welding apparatus 100 provided in this disclosure can adjust the height of each of the pair of rotating parts 170, the rotation speed of each of the pair of rotating parts 170, and the moving speed of the first shelf 130 in real time based on the shape and / or size of the base material 180. Therefore, it can determine the heating conditions based on the shape or size of the base material 180 and effectively perform welding based on the optimized heating conditions, unaffected by the shape or size of the base material 180. Moreover, the induction heating welding apparatus 100 provided in this disclosure welds based on the temperature of each part of the base material 180, thus preventing temperature deviations in the target object and providing the advantage of uniform welding of the entire target object.

[0123] The induction heating welding apparatus 100 provided in this disclosure can be applied, for example, to the field of communication filters. Specifically, the induction heating welding apparatus 100 can minimize porosity caused by welding, and can form a uniform shape and quality of the welded part of the welded object, thereby improving the RF (Radio Frequency) characteristics of the filter device.

However, this is merely an illustrative description of the technical concept of some embodiments of the present invention.

For those skilled in the art, various modifications and variations can be made without departing from the essential characteristics of this embodiment. Therefore, this embodiment is for illustration, not limitation, of the technical concept, and these embodiments are not intended to limit the scope of the technical concept of this embodiment.
