[0017] An auxiliary debugging module for position debugging of the welding part 3, including The main body 1; The limiting part 11, the limiting part 11 is arranged on the main body 1, and the limiting part 11 can be in limiting cooperation with the welding part 3 to fix the relative position of the auxiliary debugging module and the welding part 3; The laser part 2, the laser part 2 is arranged on the main body 1, the width direction of the main body 1 is defined as the first direction, and the laser part 2 can emit a cursor signal in the first direction; in the state where the relative position of the auxiliary debugging module and the welding part 3 is fixed, the marked position of the cursor signal is consistent with the projection center of the welding part 3 in the first direction.
[0018] In this embodiment, the projection center of the welding part in the first direction represents the center position of the flame ejected by the welding part. The welding part can be either a single welding torch or a combination of multiple welding torches. When the welding part is composed of multiple welding torches, the projection center of the welding part in the first direction is the common center position of the multiple welding torches, that is, the center position of the common flame.
[0019] In this embodiment, before the welding operation of the welding part 3, the heat exchanger and the workpiece to be welded, such as a nozzle, etc., need to be pre-fixed first, and then sent to the working area of the welding part 3 in sequence by a conveyor belt for welding. Under the action of the conveyor belt, each pre-fixed heat exchanger and the workpiece to be welded will reach the same position in the working area of the welding part 3. Therefore, only one position adjustment of the welding part 3 is required before the welding operation starts. The welding part 3 will perform flame welding on the reached heat exchanger and the workpiece to be welded. In the related art, the position adjustment of the welding part 3 is often judged by the human eye, so that the flame center of the welding part 3 is aligned with the welding center of the heat exchanger and the workpiece to be welded, such as the center of the nozzle. Since the diameter of the flame is large and the line of sight is blocked, the error of the human eye judgment is large, which easily causes the flame center of the welding part 3 to deviate from the welding center, resulting in uneven heating of the heat exchanger and the welded workpiece, and then welding defects, affecting the quality of the heat exchanger. In this embodiment, the auxiliary debugging module includes a limiting part 11. The limiting part 11 can be in limiting cooperation with the welding part 3 and is installed at a predetermined position on the welding part 3. After installation, the cursor emitted by the laser part 2 is the center position of the flame of the welding part 3. When the cursor signal does not reach the welding center of the heat exchanger and the workpiece to be welded, the position of the welding part 3 is adjusted according to the cursor signal so that the cursor signal is consistent with the welding center of the heat exchanger and the workpiece to be welded. At this time, the flame center of the welding part 3 will be consistent with the welding center of the heat exchanger and the workpiece to be welded, making the heat at the welding position concentrated and uniform, thereby improving the welding quality. In this embodiment, after the position adjustment of the welding part 3 is completed, the auxiliary debugging module can be removed. In other embodiments, it can be retained.
[0020] The limiting part 11 includes at least one curved surface 111, and / or, a first plane 112 and a second plane 113 at a preset angle; at least one curved surface 111 is in contact with the welding part 3, and / or, the first plane 112 and the second plane 113 at a preset angle are respectively in contact with the welding part 3; the main body 1 further includes a positioning part 114. The positioning part 114 is provided at the end of the limiting part 11. The positioning part 114 includes a positioning surface 1141. The positioning surface 1141 is perpendicular to the first direction and is in contact with the end of the welding part 3.
[0021] Such as Figure 1 And Figure 2As shown, in this embodiment, the limiting part 11 needs to be fixedly positioned with the welding part 3. The welding part 3 is a circular welding head commonly used in the industry. The limiting part 11 includes at least one curved surface 111 with the same radius as the welding part 3, forming a surface fit with the welding part 3 to fix the radial position of the auxiliary debugging module relative to the welding part 3. Further, the main body 1 further includes a positioning part 114, and the positioning part 114 is a circular cavity sleeved on the end of the welding part 3 to further form a limit. The positioning part 114 includes a positioning surface 1141, and the positioning surface 1141 is perpendicular to the extending direction of the welding part 3 and contacts the end surface of the welding part 3 to form a limit in the axial direction, thereby completely limiting the position of the auxiliary debugging module and the welding part 3, ensuring that the cursor position is consistent with the flame center position of the welding part 3. In other embodiments, if multiple rows of welding heads are used, the number of the curved surfaces 111 is correspondingly increased.
[0022] As Figure 3 and Figure 4 shown, in other embodiments, the limiting part 11 includes both the curved surface 111 and planes, including a first plane 112 and a second plane 113. The first plane 112 and the second plane 113 form a preset included angle α, 0° < α < 180°. The first plane 112 and the second plane 113 are respectively tangent to the outer surface of the welding part 3. The first plane 112 and the second plane 113 are in an "eight" shape or an inverted "eight" shape to form a fixation in the radial direction of the welding part 3. However, in some embodiments, only the curved surface 111 may contact the welding part 3 to form a radial position fixation.
[0023] As Figure 5 shown, in other embodiments, the limiting part 11 may only include planes, including a first plane 112 and a second plane 113. The first plane 112 and the second plane 113 form a preset included angle α, 0° < α < 180°. The first plane 112 and the second plane 113 are respectively tangent to the outer surface of the welding part 3. The first plane 112 and the second plane 113 are in an "eight" shape or an inverted "eight" shape to form a fixation in the radial direction of the welding part 3.
[0024] The position of the welding part 3 is limited by the curved surface 111 and / or the plane, and the operation method is simple and the position limitation is relatively accurate.
[0025] As Figure 9 shown, the main body 1 includes a mounting hole 12, and a laser part 2 is detachably arranged in the mounting hole 12.
[0026] In this embodiment, the laser part 2 is set to be detachable, which is convenient for replacement after the laser part 2 fails.
[0027] In this embodiment, the main body 1 further includes at least one fixing hole 13, and a fastener 14 is provided in at least one fixing hole 13. The fastener 14 fixes the auxiliary debugging module to the welding part 3.
[0028] After the positions of the welding part 3 and the auxiliary debugging module are defined, they are fixed by the fastener 14 to ensure that the auxiliary debugging module does not shift when the position of the welding part 3 is adjusted; in other embodiments, the auxiliary debugging module can be fixed by other means, such as magnetic attraction.
[0029] This application also discloses a debugging method, including the following steps: Clamp and fix the heat exchanger element; Install the auxiliary debugging module at a first preset position of the welding part 3 to fix the relative position between the auxiliary debugging module and the welding part 3. The first preset position is the upper part of the welding part 3. Start the auxiliary debugging module, and the auxiliary debugging module emits an induction signal; Judge whether the cursor signal reaches a second preset position, and the second preset position is the welding center of the heat exchanger element; If the cursor signal does not reach the second preset position, adjust the position of the welding part 3, and synchronously move the auxiliary debugging module and the induction signal; The induction signal emitted by the auxiliary debugging module reaches the second preset position; Stop adjusting the position of the welding part 3.
[0030] In other embodiments, the induction signal is not limited to the cursor signal, and can also be other signals such as infrared signals.
[0031] In some embodiments, installing the auxiliary debugging module at the first preset position further includes fixing the auxiliary debugging module to the welding part 3.
[0032] In this embodiment, starting the auxiliary debugging module and the auxiliary debugging module emitting an induction signal further include the following steps: the laser part 2 of the auxiliary debugging module emits a cursor signal.
[0033] In this embodiment, adjusting the position of the welding part 3 further includes the following steps: the servo motor drives the welding part 3 to perform displacement in at least one direction, the auxiliary debugging module and the welding part 3 move synchronously, and the cursor signal moves synchronously.
[0034] The welding part 3 can be displaced in at least one direction and is driven by a servo motor, and the position adjustment is relatively accurate.
[0035] In this embodiment, the steps for the induction signal emitted by the auxiliary debugging module to reach the second preset position further include that the cursor signal emitted by the auxiliary debugging module hits the surface of the heat exchanger element, the welding part 3 moves relative to the heat exchanger element, and the cursor signal moves to coincide with the second preset position of the heat exchanger element.
[0036] In some embodiments, the steps for determining whether the cursor signal reaches the second preset position further include that the vision mechanism determines whether the cursor signal reaches the second preset position.
[0037] By setting the vision structure to determine the position of the cursor signal, it is more accurate.
[0038] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
