Description

Technical Field

[0001] This invention relates to the technical field of sheet metal welding, and in particular to an automated focusing welding equipment for sheet metal parts and its application method. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. They are indispensable in our daily lives. The manufacturing process of sheet metal parts includes filament power winding, laser cutting, heavy-duty processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, and precision welding.

[0003] For example, Chinese utility model patent CN204621434U discloses a sheet metal welding and fixing device, including a base, a welding support plate, a pressure plate, and a pressure strip. The welding support plate is placed on the base, and a groove is opened in the middle of the welding support plate. The pressure plate is used to fix the sheet metal part to the welding support plate. The pressure strip has cylindrical pressure legs at both ends. A slot hole with a diameter matching the pressure leg is opened at each of the four corners of the base, so that the pressure leg can be placed in the slot hole. After the sheet metal part is fixed by the pressure plate, it is then tightened again by the pressure strip.

[0004] Regarding the aforementioned technologies, sheet metal welding and fixing devices can be applied to fixing single sheet metal parts. However, in the process of welding multiple sheet metal parts, it is necessary to consider whether the gaps at the joints of the multiple sheet metal parts meet the error range. Summary of the Invention

[0005] To address the difficulty in detecting whether the gaps at joints of multiple sheet metal parts meet the error range, this application provides an automated focusing welding device for sheet metal parts and its application method.

[0006] In a first aspect, the present invention provides an automated focusing welding equipment for sheet metal parts, which adopts the following technical solution:

[0007] An automated focusing welding device for sheet metal parts includes an automatic welding machine and a corner frame disposed on the top surface of the processing platform of the automatic welding machine. The corner frame is composed of a right-angle frame and a right-angle plate. The automatic welding machine is equipped with a calibration component for calibrating the position of the right-angle frame and the right-angle plate. The calibration component includes several calibration light meters disposed around the welding head of the automatic welding machine and several CCD detectors disposed inside the automatic welding machine. The several CCD detectors correspond to two strips of the right-angle frame respectively. The processing platform of the automatic welding machine is made of transparent tempered glass.

[0008] By adopting the above technical solution, the calibrating light instrument is moved by the displacement mechanism of the automatic welding machine, and the light emitted by the calibrating light instrument illuminates the part where the right-angle frame and the right-angle plate are combined. The light leakage at the part where the right-angle frame and the right-angle plate are combined is detected by a CCD detector. When the light leakage meets the specified error range, the welding head of the automatic welding machine can automatically weld the part where the right-angle frame and the right-angle plate are combined.

[0009] Optionally, the right-angle plate is provided with an alignment component to facilitate the assembly of the right-angle frame and the right-angle plate. The alignment component includes several alignment protrusions that are vertically fixed to the surface of the right-angle plate. The two far ends of the two strips of the right-angle frame are each provided with several alignment through slots, and the several alignment protrusions correspond to the several alignment through slots respectively.

[0010] By adopting the above technical solution, the alignment protrusions on the right-angle plate are engaged with the right-angle frame through the corresponding alignment grooves, making it easier to assemble and splice the right-angle plate and the right-angle frame.

[0011] Optionally, the automatic welding machine is provided with a correction component for positioning the right-angle frame. The correction component includes an assembly frame on the top surface of the processing platform of the automatic welding machine, a plurality of correction sleeves on the assembly frame with each straight rod away from the side wall of the right-angle frame, a correction straight rod passing through the correction sleeve, and a correction spring connecting the end of the correction straight rod to the inner side wall of the correction sleeve.

[0012] By adopting the above technical solution, the pressure cylinder is activated and the right-angle frame is moved by the pressure cylinder, so as to achieve the effect of the right-angle frame gradually approaching the assembly frame.

[0013] Optionally, the automatic welding machine is provided with a synchronization component on top for driving several straightening rods to move synchronously. The synchronization component includes a sleeve pipe connected to the ends of several straightening sleeves away from the right-angle frame. The sleeve pipe is connected to the ends of several straightening sleeves, and the end of the sleeve pipe away from the straightening sleeve is connected to a suction device.

[0014] By adopting the above technical solution, the existing suction equipment is powered on and the air is drawn from the inside of several straightening sleeves through the sleeve pipe. The straightening rod gradually retracts into the straightening sleeve until the straightening suction cup retracts into the clearance groove, thereby achieving the effect of the right angle frame and the assembly frame having close side wall contact.

[0015] Optionally, the assembly frame is provided with a locking component for locking the right-angle frame. The locking component includes a straightening suction cup hinged to the end of the straightening rod near the right-angle frame and a suction cup hose penetrating the straightening rod. One end of the suction cup hose is connected to the straightening suction cup, and the other end of the suction cup hose is connected to the gap between the end of the straightening rod away from the right-angle frame and the inner sidewall of the straightening sleeve away from the right-angle frame.

[0016] By adopting the above technical solution, the existing suction device uses a suction cup hose to draw air, which enables the correction suction cup to generate suction to adsorb the right-angle frame, thereby achieving the effect of locking the right-angle frame with the locking component.

[0017] Optionally, the diameter of the suction cup hose is smaller than the diameter of the sleeve pipe.

[0018] By adopting the above technical solution, and by setting the diameter of the suction cup hose to be smaller than the diameter of the sleeve pipe, the existing air suction equipment can first evacuate the air inside the correction sleeve through the sleeve pipe when performing air extraction, and then use the suction cup hose to enable the correction suction cup to have an adsorption effect.

[0019] Optionally, the automatic welding machine is provided with a pushing component on the top for pushing the right-angle frame. The pushing component includes a pressing cylinder on the top of the automatic welding machine, a pressing sleeve on the output shaft of the pressing cylinder, and a pressing cylinder passing through the end of the pressing sleeve near the right-angle frame.

[0020] By adopting the above technical solution, the pressure cylinder is activated and the right-angle frame is moved by the pressure cylinder, so that the right-angle frame gradually approaches the assembly frame, thereby achieving the effect of the straightening suction cup on the assembly frame contacting the surface of the right-angle frame.

[0021] Optionally, the pressing cylinder is provided with an electromagnetic component for pushing the right-angle plate. The electromagnetic component includes a locking rod provided on the circumference of the pressing cylinder and electromagnets vertically fixed at both ends of the locking rod near the right-angle plate.

[0022] By adopting the above technical solution, firstly, the electromagnets at both ends of the locking rod are engaged with the right-angle plate through the magnetic grooves, and the electromagnets are energized and activated to attract the right-angle plate. Then, the electromagnets are pushed by the output shaft of the pressure cylinder to gradually approach the right-angle frame.

[0023] Secondly, the present invention provides an application method for an automated focusing welding equipment for sheet metal parts, used to operate the aforementioned automated focusing welding equipment for sheet metal parts, comprising the following steps:

[0024] S1. The right-angle bracket and right-angle plate are placed on the top surface of the processing platform of the automatic welding machine;

[0025] S2. The pushing component pushes the right-angle frame closer to the assembly frame until the straightening suction cup on the assembly frame contacts the surface of the right-angle frame;

[0026] S3. The suction device uses a synchronization component to evacuate air from several straightening sleeves until the right-angle frame and the side wall of the assembly frame are close to each other.

[0027] S4. The electromagnetic component attracts the right-angle plate, and the electromagnet approaches the right-angle frame through the pushing component until the alignment protrusion is engaged with the right-angle frame through the alignment groove.

[0028] S5. The calibrating light beam is moved by the displacement mechanism of the automatic welding machine, and the light beam emitted by the calibrating light beam is directed at the part where the right-angle frame and the right-angle plate meet.

[0029] S6. If the light leakage at the junction of the right-angle frame and the right-angle plate is within the error range after inspection by a CCD detector, the welding head of the automatic welding machine will weld the junction of the right-angle frame and the right-angle plate.

[0030] By adopting the above technical solution, the right-angle frame and right-angle plate of the angle bracket are placed on the top of the processing platform of the automatic welding machine; the pressure cylinder pushes the right-angle frame to move through the pressure cylinder, so that the right-angle frame gradually approaches the assembly frame until the straightening suction cup on the assembly frame contacts the surface of the right-angle frame; the existing suction equipment is powered on and air is drawn from the inside of the four straightening sleeves through the sleeve pipe, the straightening rod gradually retracts into the straightening sleeve until the straightening suction cup retracts into the clearance groove until the right-angle frame is in close contact with the side wall of the assembly frame; the electromagnets at both ends of the locking rod are connected by... The magnet is engaged with the right-angle plate by a groove, and the electromagnet is energized and attracted to the right-angle plate. Then, the electromagnet is pushed closer to the right-angle frame by the output shaft of the pressure cylinder. When the alignment protrusion on the right-angle plate is engaged with the right-angle frame by the corresponding alignment groove, the calibration light instrument moves through the displacement mechanism of the automatic welding machine. The calibration light instrument emits light that shines on the part where the right-angle frame and the right-angle plate meet. The light leakage at the part where the right-angle frame and the right-angle plate meet is detected by a CCD detector, and the welding head of the automatic welding machine welds the part where the right-angle frame and the right-angle plate meet.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The calibrating light meter is moved by the displacement mechanism of the automatic welding machine. The light emitted by the calibrating light meter illuminates the part where the right-angle frame and the right-angle plate are combined. The light leakage at the part where the right-angle frame and the right-angle plate are combined is detected by a CCD detector. When the light leakage is within the specified error range, the welding head of the automatic welding machine can automatically weld the part where the right-angle frame and the right-angle plate are combined.

[0033] 2. The existing suction equipment is powered on and starts up, and air is drawn from inside several straightening sleeves through the sleeve pipe. The straightening rod gradually retracts into the straightening sleeve until the straightening suction cup retracts into the clearance groove, thereby achieving the effect of the right angle frame and the assembly frame having close side wall contact.

[0034] 3. By setting the diameter of the suction cup hose to be smaller than the diameter of the sleeve pipe, the existing air suction device can first evacuate the air inside the correction sleeve through the sleeve pipe when pumping air, and then the suction cup hose enables the correction suction cup to have an adsorption effect.
