Description

Technical Field

[0001] The present invention relates to the technical field of corrugated sheet welding equipment, and particularly to a wide-width corrugated sheet intelligent spot welding equipment and process. Background Art

[0002] A corrugated sheet is a sheet with a corrugated shape, which has the characteristic of a large surface area. Based on this characteristic, the corrugated sheet has good heat dissipation performance, so it is often used to prepare boxes with heat dissipation requirements, such as corrugated fuel tanks. However, the shape of the corrugated sheet also causes its strength to decrease and it is easy to deform. Therefore, during processing, reinforcing ribs need to be welded on the corrugated sheet to increase the strength. The welding method generally uses spot welding. Spot welding refers to a welding method in which columnar electrodes are used to form solder joints between the contact surfaces of two overlapping workpieces. During spot welding, the workpieces are first pressed tightly in contact, and then the current is switched on. Under the action of resistance heat, the contact part of the workpieces melts, and then welding can be carried out. For example, the Chinese utility model patent with the authorization announcement number CN212094953U discloses a corrugated sheet reinforcing rib spot welder, which includes two support plates and two side plates. On the front left side in front of the front support plate, a first servo motor is connected by screws, and a rotating shaft is rotatably connected between the two support plates. However, the current spot welding equipment has the following defects when welding corrugated sheets:

[0003] When the current welding equipment welds at the melting point position, the welding rod directly makes point contact with the melting point to form a solder joint, and it cannot move in a small stroke. It cannot be compared with the weld pattern formed by manual spot welding. The area of the welded part is small and the welding quality is poor; and due to the special shape of the corrugated sheet, its strength will be relatively poor. After being fixed, when performing the operation of pressing the reinforcing rib, it is easy to cause deformation at the high bending position of the corrugated sheet, especially for wide-width corrugated sheets, which are more likely to deform, resulting in the phenomenon of deformation of the corrugated sheet after welding.

[0004] Therefore, we propose a wide-width corrugated sheet intelligent spot welding equipment and process to solve the above problems. Summary of the Invention

[0047] Embodiment 3:

[0048] Please refer to Figures 1-9 , which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. This embodiment provides a process for a wide-width corrugated sheet intelligent spot welding device, including the following steps:

[0049] Step 1: Place the corrugated sheet on the surface of the fixed table 21 on the fixed component 2. The two first cylinders 29 drive the sliding plate 26 to move, and the clamping blocks 27 are used to clamp both sides of the corrugated sheet, and make the highest point position of the corrugated sheet directly above a part of the top plate 23. After clamping the corrugated sheet, the part of the top plate 23 corresponding to the highest point position of the corrugated sheet moves upward under the action of the third cylinder 215, and the top bar 24 is used to support the bottom of the highest point position of the corrugated sheet. At the same time, the second cylinder 214 drives the lower electrode post 211 to move upward to contact the corrugated sheet;

[0050] Step 2: Place the reinforcing rib at the position where welding is required on the corrugated sheet. Then, the three-axis moving component 3 drives the welding head component 4 to move to a position on one side of the reinforcing rib. Fix the welding rod on the welding rod fixing head 49 on the welding head component 4. Then, the carrying block 54 in the pressing component 5 moves to a position directly above the reinforcing rib. Then, the fourth cylinder 55 drives the pressing rod 56 to move downward, and the pressing column 57 is used to press the top surface of the reinforcing rib, and the upper electrode 58 contacts the reinforcing rib;

[0051] Step 3: The capacitor module 11 is activated, and the temperature at the contact between the corrugated sheet and the reinforcing rib rises to form a melting point. The three-axis moving assembly 3 drives the welding head assembly 4 to move to the melting point position for welding. During welding, the first micro cylinder 410 and the second micro cylinder 412 drive the welding rod to move in a profiling manner, forming a weld pattern at the welding point. After welding is completed, repeat Step 2, place a new reinforcing rib, and successively weld multiple reinforcing ribs. During welding, the welding rod moves in a profiling manner to form a weld pattern, increasing the area of the welding point.

[0052] Embodiment 4:

[0053] Please refer to Figures 1-9 , which is the fourth embodiment of the present invention. Based on the above three embodiments, when the present invention is used, the corrugated sheet is placed on the surface of the fixed table 21 on the fixing component 2. The two first cylinders 29 drive the sliding plate 26 to move, and the clamping blocks 27 are used to clamp both sides of the corrugated sheet, and the highest point position of the corrugated sheet is located directly above a part of the top plate 23. After clamping the corrugated sheet, the part of the top plate 23 corresponding to the highest point position of the corrugated sheet moves upward under the action of the third cylinder 215, and the top bar 24 is used to support the bottom of the highest point position of the corrugated sheet. At the same time, the second cylinder 214 drives the lower electrode post 211 to move upward to contact the corrugated sheet; the reinforcing rib is placed at the position on the corrugated sheet that needs to be welded. Then, the three-axis moving assembly 3 drives the welding head assembly 4 to move to a position on one side of the reinforcing rib. A welding rod is fixed on the welding rod fixing head 49 on the welding head assembly 4. Then, the carrying block 54 in the pressing component 5 moves to a position directly above the reinforcing rib. Then, the fourth cylinder 55 drives the pressing rod 56 to move downward, and the pressing column 57 is used to press the top surface of the reinforcing rib, and the upper electrode 58 contacts the reinforcing rib; the capacitor module 11 is activated, and the temperature at the contact between the corrugated sheet and the reinforcing rib rises to form a melting point. The three-axis moving assembly 3 drives the welding head assembly 4 to move to the melting point position for welding. During welding, the first micro cylinder 410 and the second micro cylinder 412 drive the welding rod to move in a profiling manner, forming a weld pattern at the welding point. After welding is completed, repeat Step 2, place a new reinforcing rib, and successively weld multiple reinforcing ribs; when the welding head assembly 4 of the present invention is welding, after adjusting the angle through the rotating block 42, the first dovetail groove 44 and the second dovetail groove 46 are on the vertical plane of this angle. The first micro cylinder 410 and the second micro cylinder 412 can drive the welding rod fixing head 49 to move in two axes on this plane, and can move in a profiling manner at the melting point to form a weld pattern. Compared with the welding of the welding point, the welding area is larger, closer to manual welding, and the welding quality is higher; the fixing component 2 of the present invention is used to fix the corrugated sheet. After fixing, the top plate 23 rises to support the bottom of the high position of the corrugated sheet through the top bar 24, forming a support to prevent the corrugated sheet from deforming when the reinforcing rib is pressed down, and is more suitable for spot welding of wide-width corrugated sheets.

[0054] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
