Description

Technical Field

[0001] This invention relates to the field of automotive repair equipment technology, and more particularly to a sheet metal repair machine and its control method. Background Technology

[0002] With the development of the automotive industry, body materials are showing a diversified trend of "steel as the main material and aluminum as the widespread use." Traditional gasoline-powered vehicles mainly use cold-rolled steel sheets (iron-based materials) for their bodies, which have a high melting point (approximately 1538℃) and high structural strength, requiring high-power repair equipment for reshaping. New energy vehicles (especially mid-to-high-end models), driven by lightweight requirements, widely use aluminum alloy bodies, which have a low melting point (approximately 660℃) and high conductivity (three times that of iron). The repair process requires precise control of temperature and current to avoid burn-through or material embrittlement. This material difference places a core requirement on sheet metal repair equipment: "dual-material compatibility." This equipment is widely used for repairing both steel and aluminum alloy bodies, such as dents and wrinkles in areas like doors, hoods, and fenders. When repairing aluminum bodies for new energy vehicles, specialized tools are required to prevent cracking of the aluminum material.

[0003] However, in actual use, the aforementioned sheet metal repair machines have several drawbacks. First, they have poor compatibility with vehicle body materials. When repairing a vehicle, there may be both steel and aluminum parts. For different materials, it is necessary to move, switch, and adjust another machine, which wastes time and increases maintenance costs. Second, the repair equipment composed of a two-in-one dual integrated structure usually has poor heat dissipation performance. Long-term continuous operation can easily trigger overheat protection, interrupt the repair process, and affect work efficiency. Summary of the Invention

[0004] The technical solution to be solved by the present invention is: In view of the shortcomings of the prior art, the present invention provides a sheet metal repair machine and its control method, which solves the problems of poor compatibility with car body materials and poor heat dissipation performance.

[0005] The technical solution adopted in this invention is: a sheet metal repair machine, including a repair machine body, the repair machine body including a housing, a control unit disposed inside the housing, and a heat sink disposed inside the housing, the heat sink being electrically connected to the control unit, a control panel being disposed on the front side of the housing, side air inlets being disposed on both sides of the housing, and a rear air outlet being disposed on the rear side of the housing, the control unit including a controller, a first transformer suitable for aluminum material repair and a second transformer suitable for iron material repair, both the first transformer and the second transformer being electrically connected to the controller, and a switch for switching between aluminum material repair mode and iron material repair mode being disposed on the control panel, the switch being electrically connected to the controller.

[0006] Preferably, the control panel is provided with a first display screen for displaying aluminum material repair parameters and a second display screen for displaying iron material repair parameters. Both the first and second display screens are electrically connected to the controller. When the repair machine is in aluminum material repair mode, the first display screen lights up and the second display screen turns off; when it is in iron material repair mode, the first display screen turns off and the second display screen lights up.

[0007] Preferably, the control panel is further provided with a first light strip surrounding the first display screen and a second light strip surrounding the second display screen. Both the first and second light strips are electrically connected to the controller. When the repair machine is in aluminum repair mode, the first light strip is lit and the second light strip is turned off; when it is in iron repair mode, the first light strip is turned off and the second light strip is lit.

[0008] Preferably, it also includes a movable base, on which the repair machine body is detachably connected.

[0009] Preferably, the movable base is equipped with a cooler, and the upper end of the movable base is provided with an air inlet channel, while the lower end of the movable base is provided with an air outlet channel. When the repair machine is placed on the mobile base and the cooler is turned on, air enters from the gap between the sheet metal repair machine and the mobile base, then enters the interior of the mobile base through the air inlet channel, and finally flows out through the air outlet channel.

[0010] Preferably, the bottom of the housing has a lower air outlet, and the bottom sides of the housing have air inlets. The movable base has an air inlet chamber and an exhaust chamber. A blower is installed in the air inlet chamber, and an exhaust fan is installed in the exhaust chamber. The power of the blower is greater than that of the exhaust fan. The upper sides of the movable base have air outlets matching the air inlets, which communicate with the air inlet chambers. Air inlet channels are provided on both sides of the movable base, communicating with the air inlet chambers. An air outlet channel is provided at the lower end of the movable base, and a ventilation channel is provided at the upper end of the movable base. Both the air outlet channel and the ventilation channel communicate with the exhaust chamber. When the repair machine is placed on the mobile base and the blower and exhaust fan are turned on, the air inlet and outlet are matched and connected. At this time, air enters the air inlet chamber from the air inlet channel, then enters the machine casing after passing through the air outlet and the air inlet, and then enters the exhaust chamber through the lower air outlet and ventilation channel, and finally is discharged from the air outlet channel.

[0011] Preferably, the mobile base also includes a processor, a contact switch, and a first wireless communication module. The control unit further includes a second wireless communication module. The processor is communicatively connected to the controller via the first and second wireless communication modules. The contact switch is electrically connected to the processor and is located at the air outlet. When the sheet metal repair machine is placed on the mobile base and the air outlet and air inlet are properly matched, the contact switch is triggered. The processor sends a trigger signal to the controller, which then controls the radiator to stop working. At the same time, the processor controls the blower and exhaust fan to work.

[0012] Preferably, the top of the housing is provided with a V-shaped air guide plate for guiding air to the bottom of the housing, and the two sides of the V-shaped air guide plate are inwardly concave arc edges.

[0013] Preferably, the bottom of both sides of the housing is provided with arc-shaped baffles for covering the air intake interface. One end of the arc-shaped baffle is rotatably connected to the housing on one side of the air intake interface, and the other end of the arc-shaped baffle is magnetically attached to the housing on the other side of the air intake interface. The upper end of the movable base is provided with arc-shaped protrusions on both sides, and the air outlet is located on the arc-shaped protrusions. When the arc-shaped baffle is attached to the housing, the air intake interface is closed. When the arc-shaped protrusions open the arc-shaped baffle, the air intake interface and the air outlet are matched and connected.

[0014] A control method for a sheet metal repair machine, comprising the following steps: S1. When the sheet metal repair machine is working normally, the controller will control the radiator to start. At this time, air enters from the air inlets on both sides of the machine housing and then exits from the air outlet on the rear side of the machine housing, thereby dissipating heat from the inside of the machine housing. S2. When the sheet metal repair machine is placed on the mobile base and the air outlet and air inlet are properly matched, the contact switch is triggered and a trigger signal is sent to the processor. The processor sends the trigger signal to the controller through the first wireless communication module and the second wireless communication module. The controller controls the heat sink to stop working, and at the same time the processor controls the intake fan and exhaust fan to work. At this time, air enters the intake chamber from the intake channel, then enters the machine casing after passing through the air outlet and the air inlet, and then enters the exhaust chamber through the lower air outlet and the ventilation channel, and finally is discharged from the air outlet.

[0015] Compared with the prior art, the present invention has the following advantages: it adopts a switching module to directly switch between aluminum and iron repair modes, which is compatible with the integrated repair of steel and aluminum car bodies, and has a database and memory function. In this way, the system can automatically call the preset optimal parameters when switching, and the repair machine can start working immediately, thus achieving a combination of efficiency and energy saving.

[0016] The output end of the welding torch uses a dedicated quick plug and socket, which is efficient, convenient, and easy to use, improving work efficiency and service life.

[0017] It uses dual LCD screens, and the specific mode is indicated by the display screen and light strip, which makes it clearer and less likely to be mistaken.

[0018] Furthermore, it adopts a base design to aid in heat dissipation, resulting in better overall heat dissipation performance.

[0019] The repair machine has air intake channels on both sides, and an air outlet on the mobile base. The mobile base is divided into an air supply chamber and an exhaust chamber. After the repair unit is placed on the mobile base, the protruding air outlet can be inserted into the air intake port to complete the connection. This turns the air supply chamber on the mobile base into a supply chamber for the repair unit. After cooling, the air is drawn out of the repair unit and then exhausted from below. For a dual-mode high-power repair machine, this provides better heat dissipation, especially better dust prevention. This is because there is more space on the mobile base to set up the air intake chamber and filters such as HEPA filters and filter screens, making it suitable for dusty factory environments.

[0020] The air inlet and outlet ports are designed with this structure and are equipped with contact switches. When the repair unit is placed on the mobile base, the cooling fan on the repair unit is turned off, while the blower and exhaust fan inside the mobile base are turned on. This changes the direction of the internal cooling airflow. In particular, the air inlet channels are on the left and right sides of the mobile base, and the air supply power of the air inlet chamber is greater than the suction power of the exhaust, keeping the inside of the repair unit under positive pressure. This can achieve reverse dust removal from the original air inlet of the repair unit.

[0021] A V-shaped air guide plate is installed so that the air entering the casing can be guided downwards, which can better dissipate heat from the control unit inside the casing. Attached Figure Description

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1: A sheet metal repair machine, such as Figure 1 and Figure 2 As shown, the device includes a repair machine body 1, which comprises a casing 2, a control unit, and a heat sink 3, wherein: A control panel 4 is located on the front of the casing 2, a rear air outlet 6 is located on the rear of the casing 2, side air inlets 5 are located on the left and right sides of the casing 2, an H-shaped handle is located on the top of the casing 2, and a bottom air outlet 16 is located on the bottom of the casing 2. The control panel 4 includes a toggle switch 9, a first display screen 10, a first button, a first output interface, a second display screen 11, a second button, and a second output interface, wherein: The first display screen 10 is used to display aluminum material repair parameters, and the first display screen 10 will turn off when in iron material repair mode; The first button is used to adjust the aluminum repair parameters; The first output interface is used to connect the aluminum material repair execution component. The second display screen 11 is used to display iron material repair parameters, and the second display screen 11 will turn off when in aluminum material repair mode; The second button is used to adjust the iron repair parameters; The second output interface is used to connect the iron material repair execution component. The switching module is used to switch between aluminum repair mode and iron repair mode; The control unit includes a controller, a first transformer 7, and a second transformer 8, wherein: The first transformer 7 provides a maximum short-circuit current of 7500A for aluminum material repair; The second transformer, number 8, provides a maximum short-circuit current of 4000A for iron material repair. The controller is used to control the entire system; The radiator 3 is installed at the air outlet inside the casing 2 to expel hot air from the casing 2. This system mainly combines the aluminum material repair system and the iron material repair system into a single housing 2, and switches between them via a switch 9. Therefore, the overall system remains largely unchanged and consists of standard configurations, so it is not elaborated upon in this application.

[0031] Example 2: The difference from Embodiment 1 is that Embodiment 2 includes a movable base 12, on which the repair machine body 1 can be placed for use. This not only facilitates movement, but also includes a cooler 13 (i.e., a fan) inside the movable base 12. An air inlet channel 14 is provided at the upper end of the movable base 12, and an air outlet channel 15 is provided at the lower end of the movable base 12. After the repair machine body 1 is placed on the movable base 12, there is a gap between it and the movable base 12. The upper surface of the movable base 12 is recessed inward to form a groove. The air inlet channel 14 is located on the upper surface of this groove. When the cooler 13 is activated, air will enter through the gap, carrying away some of the heat from outside the casing 2. Then, the air enters the movable base 12 through the air inlet channel 14 and finally flows out through the air outlet channel 15, forming a heat dissipation channel.

[0032] Example 3: The difference from Embodiment 2 is that in Embodiment 3, the movable base 12 has air intake channels 23 on both sides, the air intake channel 14 at the upper end of the movable base 12 is changed to a ventilation channel 25, the air outlet channel 15 at the lower end of the movable base 12 is changed to an exhaust channel 24, and the interior of the movable base 12 is changed to an air supply chamber and an exhaust chamber 19. The air intake channel 23 is connected to the air supply chamber, and the ventilation channel 25 and the exhaust channel 24 are connected to the exhaust chamber 19. An intake fan is installed in the air supply chamber, and an exhaust fan 21 is installed in the exhaust chamber 19. The power of the intake fan is greater than the power of the exhaust fan. Furthermore, two arc-shaped protrusions 28 are provided at the upper end of the movable base 12, and the arc-shaped protrusions 28 are provided with... An air outlet 22 is provided, and air inlets 17 are provided on the lower ends of both sides of the housing 2. An arc-shaped baffle 27 is provided on each air inlet 17 to block it. One end of the arc-shaped baffle 27 is rotatably connected to the housing 2 on one side of the air inlet 17, and the other end is magnetically attached to the housing 2 on the other side of the air inlet 17. When the repair machine body 1 is not placed on the movable base 12, the arc-shaped baffle 27 is attached to the housing 2, thus sealing the air inlet 17. When the repair machine body 1 is placed on the movable base 12, the arc-shaped baffle 27 is pushed up by the arc-shaped protrusion 28, thereby connecting the air inlet 17 with the air outlet 22 and sealing it relative to the external connection (i.e.,...). While small gaps may allow air leakage, the two are generally well-matched. Furthermore, after the repair machine body 1 is placed on the mobile base 12, the space between the repair machine body 1 and the mobile base 12 is relatively sealed (i.e., small gaps may allow air leakage, but the two are generally well-matched). This space is only connected to the interior of the casing 2 through the lower air outlet 16 and to the interior of the mobile base 12 through the ventilation channel 25. That is, when the repair machine body 1 is placed on the mobile base 12 and the air inlet 17 matches the air outlet 22, and the air intake and exhaust fans are activated, air will enter the air supply chamber from the air intake channel 23, and then pass through the air outlet 22 and the air supply... Air enters the housing 2 through the air inlet 17, then carries away the heat inside the housing 2 and flows out through the lower air outlet 16, then flows into the movable base 12 through the ventilation channel 25, and finally exits through the air outlet 24, forming a complete heat dissipation channel. Because the air supply chamber is inside the movable base 12, the overall size can be made larger, allowing for the installation of filters such as HEPA filters and filter screens inside. This is suitable for dusty factory environments, preventing dust from entering the housing 2. Furthermore, because the power of the intake fan is greater than that of the exhaust fan, some air may be discharged from the side air inlet 5 after entering the housing 2, which is equivalent to reverse dust removal from the side air inlet 5.

[0033] Example 4: The difference from Embodiment 3 is that in Embodiment 4, a V-shaped air guide plate 26 is provided inside the top of the housing 2, and the two sides of the V-shaped air guide plate 26 are inwardly concave arc edges. In this way, the air flows into the housing 2 through the air inlet 17 and then flows to the top of the housing 2. Then, under the action of the air guide plate 26, it blows downward to cool down the internal control unit as much as possible. Then, it flows out from the lower air outlet 16, achieving better heat dissipation and cooling.

[0034] Example 5: The difference from Embodiment 3 is that in Embodiment 5, a contact switch is provided at the air outlet 22 position, and a first wireless communication module and a processor are provided inside the movable base 12. The contact switch, the air intake fan, the air exhaust fan, and the first wireless communication module are all electrically connected to the processor. The control unit also includes a second wireless communication module. That is, as long as the repair machine body 1 is placed on the movable base 12 and the air outlet 22 matches the air intake fan 17, this contact switch will be triggered. At this time, the processor will send a trigger signal to the controller, and then the controller will control the heat sink 3 to stop working. At the same time, the processor controls the air intake fan and the air exhaust fan 21 to work, so that the heat dissipation channel can be switched. At this time, the air enters the air intake chamber 18 from the air intake channel 23, and then enters the machine casing 2 after passing through the air outlet 22 and the air intake fan 17. After that, it enters the exhaust chamber 19 through the lower air outlet 16 and the ventilation channel 25, and finally exits from the air outlet 24.
