The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] The embodiment of the present application provides a conveying and positioning method for a long plate material, wherein the conveying and positioning method for the long plate material adopts a conveying and positioning device, wherein the long plate material has a plurality of areas to be welded, and the conveying and positioning device comprises a support frame and a feeding conveying mechanism, a preheating table, a feeding sensor, a clamping platform, a visual positioning mechanism, a discharging sensor, and a discharging conveying mechanism arranged on the support frame, such as Figure 1 As shown, the method comprises the following steps:

[0027] S2, preheating: the feed conveying mechanism uses a first conveying speed to convey the long plate material to the preheating table. When the sensing signal of the feed sensor changes from zero to yes, the conveying speed of the feed conveying mechanism is adjusted to a second conveying speed, wherein the second conveying speed is lower than the first conveying speed, and drives the long plate material to move away from the clamping platform until the sensing signal of the feed sensor changes from yes to no, and then stops conveying the long plate material; after stopping for a set period of time, the preheating of the area to be welded is completed.

[0028] In this embodiment, the feed sensor is located between the preheating table and the clamping platform. When the feed sensor sensing signal changes from none to yes, the conveying speed is adjusted to the second conveying speed, and the long plate material is driven to move away from the clamping platform to prevent the feed conveying mechanism and the long plate material from slipping, or the feed sensor sensing delay causing the long plate material to overshoot, thereby ensuring that the area to be welded of the long plate material is located on the preheating table, thereby improving the feed positioning accuracy of the long plate material.

[0029] In this embodiment, after the feed conveying mechanism conveys the long plate material to the preheating table, it stops for a set time to preheat the area to be welded before the welding line, so that the temperature of the area to be welded is stable during the welding line. By reducing the temperature gradient between the area to be welded and the long plate material, the stress of the welding line is reduced, the generation of welding line cracks is prevented, and the situation of welding line failure due to unstable temperature is avoided.

[0030] In this embodiment, the set time can be set according to actual needs, and this application does not limit it here.

[0031] S3, fixed: the feeding conveying mechanism adopts the second conveying speed, and after conveying the long plate material to the clamping platform according to the set distance, stops conveying the long plate material, wherein the set distance is the distance between the two areas to be welded; the clamping platform clamps the long plate material, and the visual positioning mechanism identifies the area to be welded and obtains the deviation distance; the area to be welded located in the clamping platform is welded, and the next area to be welded is located on the preheating table.

[0032] In this embodiment, the feed conveying mechanism conveys the long plate material to the clamping platform according to the set distance, so that the area to be welded after preheating is located in the clamping platform, and the next area to be welded is located on the preheating table, thereby improving the heating efficiency of the long plate material.

[0033] In this embodiment, a clamping platform is used to clamp the long plate material, so as to avoid shaking of the long plate material when a wire welding machine is used to weld the area to be welded, thereby improving the welding accuracy.

[0034] In this embodiment, a visual positioning mechanism is used to visually locate the area to be welded and obtain the deviation distance to adjust the transportation of the next area to be welded, improve the conveying accuracy of the long plate material, and avoid exceeding the area to be welded when welding.

[0035] For example, the visual positioning mechanism can use a CCD camera. After the CCD camera obtains the current photo, it compares it with the pre-stored photo of the area to be welded, so as to obtain the deviation distance; of course, the visual positioning mechanism can also use other visual positioning mechanisms, and this application is not limited here.

[0036] S4, coordination: after the welding line of the area to be welded is completed, the clamping platform releases the long plate material, and the feeding conveying mechanism uses the second conveying speed to convey the long plate material to the discharge sensor; when the sensing signal of the discharge sensor changes from none to yes, the discharge conveying mechanism and the feeding conveying mechanism stop conveying the long plate material after conveying the long plate material according to the calibration distance, wherein the calibration distance is the set distance plus the deviation distance, and the next area to be welded is located in the clamping platform.

[0037] In this embodiment, the discharging conveying mechanism and the feeding conveying mechanism are separated to prevent the discharging conveying mechanism and the feeding conveying mechanism from crossing the preheating table and the clamping platform, so that the accuracy of transporting long board materials is not affected by the high temperature of the preheating table and the clamping platform, thereby improving the transportation accuracy.

[0038] In this embodiment, after using a visual positioning mechanism to visually locate the area to be welded and obtain the deviation distance, the discharging conveying mechanism and the feeding conveying mechanism transport the long plate material according to the calibrated distance, thereby improving the conveying accuracy of the long plate material. Through real-time adjustment, the alignment accuracy between multiple areas to be welded and the clamping platform and the preheating table is improved, thereby reducing the situation where the area to be welded exceeds the working area of ​​the wire welding machine due to cumulative deviation.

[0039] S5, discharging: repeat the fixing step and the coordination step until each of the areas to be welded completes the welding line; when the sensing signal of the feed sensor changes from being present to being absent, the feed conveying mechanism stops; when the sensing signal of the discharging sensor changes from being present to being absent, the discharging conveying mechanism stops.

[0040] In this embodiment, the fixing step and the coordination step are repeated to meet the requirements of conveying, guiding, positioning and heating of multiple areas to be welded on the long plate material.

[0057] In this embodiment, the synchronous belt is driven by a motor to move. The synchronous belt serves as a carrier for transporting long board materials.

[0063] Furthermore, the side pressing device and the Y-direction pressing device are arranged on the same side of the support frame, thereby avoiding positioning the side edges of the long plate material in opposite directions and improving positioning accuracy.

[0064] Furthermore, the preheating table is flush with the conveyor belt to prevent the long board material from shaking during the conveying process and affecting the positioning accuracy of the above steps.

[0065] Further, the lifting device comprises a first driving member, a top plate and a first heating rod, the first driving member is used to drive the top plate to rise and fall, and the first heating rod is located inside the top plate;
