Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a multifunctional welding machine that integrates laser and electric arc. Background Technology

[0002] There are various welding methods available for users to choose from, such as laser welding and arc welding. The advantages of laser welding are high speed, large depth, and small deformation, while the disadvantages are high cost, small weld seam, and limited thickness.

Users can choose the appropriate welding method according to their own needs.

[0003] However, different welding methods require specialized welding machines. When both laser welding and arc welding are required in certain scenarios, workers have to carry two welding machines, which is inconvenient. However, due to mutual interference between the operating components, the existing welding machine structure cannot be compatible with the two welding methods. Utility Model Content

[0033] In some embodiments of this utility model, both the first switch module 310 and the second switch module 410 include an AC relay.

[0034] This utility model is a multi-functional welding machine integrating laser and electric arc welding. Within the housing 100, a first chamber 130 and a second chamber 140 are separated by a partition plate 110. The wire feeding module 330 of the electric arc welding module 300 and the laser generating module 430 of the laser welding module 400, which may interfere with each other, are placed in the first chamber 130 and the second chamber 140, respectively. Other modules can be arranged reasonably. The control module 500 is connected to the electric welding drive module 320 and the laser drive module 420 to control their operation. When using the electric arc welding module 300, the control module 500... The control module 500 can control the first switch module 310 to be turned on and the second switch module 410 to be turned off. The power plug 200 supplies power to the arc welding module 300, which then operates, while the laser welding module 400 stops. Similarly, when using the laser welding module 400, the control module 500 can control the second switch module 410 to be turned on and the first switch module 310 to be turned off.

[0035] In some embodiments of this utility model, the welding drive module 320 includes a first rectifier unit, an inverter unit, a transformer unit, and a second rectifier unit connected in sequence. The input terminal of the first rectifier unit is connected to the tail end of the first switch module 310, and the output terminal of the second rectifier unit is electrically connected to the arc welding gun 340. The control module 500 is connected to the controlled terminal of the inverter unit to control the operation of the inverter unit.

Similarly, the second rectifier unit may include a full-bridge rectifier or a full-wave rectifier composed of diodes.

[0037] In some embodiments of this utility model, such as Figure 3 As shown, the housing 100 has a heat exchanger 700 in the second chamber, the laser generating module 430 is disposed in the heat exchanger 700, and the housing 100 has a first fan 810 facing the second chamber 140.

[0038] Since the laser generating module 430 generates a lot of heat, a dedicated first fan 810 and heat exchanger 700 can be set up to dissipate heat from the laser generating module 430, thereby preventing the laser generating module 430 from overheating and causing damage to its components, or even transferring heat to other modules and causing damage to the components of other modules.

[0039] In some embodiments of this utility model, such as Figure 3 As shown, the heat exchanger 700 includes multiple heat exchange plates 710 that are stacked at intervals and connected to each other. An air duct is formed between adjacent heat exchange plates 710. The laser generating module 430 is disposed on the heat exchange plate 710 at the first end of the heat exchanger 700. The housing 100 is provided with an air outlet 170. The first fan 810 is located at the first end of the air duct, and the air outlet 170 is located at the tail end of the air duct.

[0040] The heat exchange plate 710 at the beginning of the heat exchanger 700 comes into contact with the components of the laser generating module 430. Heat is transferred to the heat exchange plate 710 at the beginning of the heat exchanger 700 and then transferred layer by layer to other heat exchange plates 710. Meanwhile, the airflow flows through each air duct, and the airflow and the heat exchange plates 710 on both sides of the air duct are in full contact, thereby achieving efficient heat exchange.

[0041] In some embodiments of this utility model, such as Figure 2 , 3 As shown, a support plate 120 is provided on the top of the first chamber 130 and the second chamber 140 to separate the electrical cavity 150. The control module 500 and the welding drive module 320 are disposed on the support plate 120 and located in the electrical cavity 150.

[0042] An electrical cavity 150 is provided at the top of the first chamber 130 and the second chamber 140. The control module 500 is located in the electrical cavity 150. The control module 500 can be connected to the electronic components in the first chamber 130 or the second chamber 140 below through wires or busbars, respectively, to accommodate more areas. A circuit board can be provided on the carrier plate 120, and the electronic components of the control module 500 and the welding drive module 320 can be provided on the circuit board.

[0043] In some embodiments of this utility model, such as Figure 3 As shown, the housing 100 is provided with a second fan 820, which faces the electrical cavity 150. The second fan 820 can blow air to cool the control module 500 and the welding drive module 320 located in the electrical cavity 150.

[0044] Generally speaking, the laser generating module 430 generates a lot of heat, and the control module 500 and the welding drive module 320 also generate heat. While focusing on cooling the laser generating module 430, it is also necessary to simultaneously cool the control module 500 and the welding drive module 320. In some embodiments of this utility model, such as... Figure 3 As shown, the first fan 810 and the air outlet 170 are directly opposite each other. The housing 100 is provided with a flow guide 160 in the electrical cavity 150. The flow guide 160 is used to drive the airflow in the electrical cavity 150 to converge to the air outlet 170.

[0045] The first fan 810 and the air outlet 170 face each other. The airflow driven by the first fan 810 enters the second chamber 140 from the outside and can directly pass through the heat exchanger 700, and then exits in a straight line from the air outlet 170, reducing the obstruction in the airflow direction, ensuring the airflow speed, and improving the heat dissipation efficiency. The airflow driven by the second fan 820 enters the electrical cavity 150 from the outside and dissipates heat for the control module 500 and the welding drive module 320. After being guided by the flow guide 160, it can also be discharged from the air outlet 170.

[0046] In some embodiments of this utility model, the drainage portion 160 includes an inclined or arc-shaped surface disposed on the inner wall of the electrical cavity 150. The electrical cavity 150 is connected to the second chamber 140 through the drainage portion 160, and the position where the second chamber 140 is connected to the electrical cavity 150 is located between the air outlet 170 and the heat exchanger 700.

[0047] The inclined or curved surface can guide the airflow into the second chamber 140. The second chamber 140 is connected to the electrical cavity 150 between the air outlet 170 and the heat exchanger 700. The heat emitted by the control module 500 and the welding drive module 320 will not affect the heat dissipation of the laser generation module 430.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
