Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic welding strip manufacturing equipment, in particular to an automatic wiping device for an annealing copper wheel. Background Art

[0002] A roll of qualified photovoltaic welding ribbon needs to go through the cooperation of multiple processes to be processed. It mainly consists of a single roll of copper wire that goes through unwinding, annealing and softening, dehydration and drying, fluxing and tinning, cooling and finally winding into a roll, thus realizing a complete set of welding ribbon production processes.

[0003] During the annealing and softening process of the photovoltaic welding ribbon, a tin-coated annealing machine is required. The tin-coated annealing machine has an annealing copper wheel for guiding the copper wire. During the annealing and softening process, the annealing copper wheel rotates at high speed without stopping. The semi-finished copper wire walks on the surface of the annealing copper wheel. The annealing copper wheel and the semi-finished copper wire will rub for a long time, resulting in oil stains / pits / deformation on the surface of the annealing copper wheel. Afterwards, a manual hand-held wiping piece (the surface of the wiping piece is rough, and the annealing copper wheel can be wiped smooth after friction with the annealing copper wheel) is required to wipe the annealing copper wheel until the surface of the annealing copper wheel is smooth and free of oil stains / pits / deformation. If you forget to wipe it, it will affect the appearance or poor performance of the finished welding ribbon.

[0004] Currently, the wiping of the annealing copper wheel is done manually, and the wiping time is difficult to control. If the wiping is forgotten, it will affect the product yield and the stability of the equipment, which will increase the workload of employees in disguise. Moreover, one operator needs to be responsible for multiple production lines at the same time. This work content occupies a lot of the operator's working time, which is not conducive to saving labor costs. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1-3 As shown, the utility model is an automatic wiping device for an annealing copper wheel, which wipes the surface of an annealing copper wheel 12 in a tin coating annealing machine according to a set time to eliminate the problems of oil stains / pits / deformation on the surface of the annealing copper wheel 12 during the annealing process of the copper wire.

[0032] The tin coating annealing machine includes a vertical plate 11, an annealing copper wheel 12 rotatably mounted on the front side of the vertical plate 11, and a motor (not shown) for driving the annealing copper wheel 12 to rotate.

[0033] The automatic wiping device for the annealing copper wheel 12 includes a pushing mechanism 21, a mounting plate 22, a wiping member 23 and a time control switch 24. The mounting plate 22 is arranged on one side of the annealing copper wheel 12 along the radial direction of the annealing copper wheel 12, and the wiping member 23 is fixedly assembled on a side surface of the mounting plate 22 close to the annealing copper wheel 12. The pushing mechanism 21 is connected to the mounting plate 22, and is used to push the mounting plate 22 to move along the radial direction of the annealing copper wheel 12, so that the wiping member 23 is close to or away from the circumferential surface of the annealing copper wheel 12. The time control switch 24 is electrically connected to the pushing mechanism 21, and is used to control the driving start and stop of the pushing mechanism 21 at a fixed time, so that the pushing mechanism 21 can push the wiping member 23 to contact the circumferential surface of the annealing copper wheel 12 within a set time period, so as to realize automatic wiping of the annealing copper wheel 12 within a set time period.

[0034] In one example, the pushing mechanism 21 includes a pushing cylinder 211, an air source (not shown), an air pressure regulating valve 212, an air pressure switch 213 and a relay 214. The pushing cylinder 211 and the air pressure switch 213 are both fixedly mounted on the front side of the vertical plate 11. The relay 214 is fixedly mounted on the air pressure switch 213. The air source is connected to the air pressure regulating valve 212, the air pressure switch 213 and the pushing cylinder 211 in sequence through an air pipe. The relay 214 is electrically connected to the air pressure switch 213 and the time control switch 24. During operation, the staff sets the time on the time switch 24 in advance. When the time display on the time switch 24 reaches the set time section, the time switch 24 controls the air pressure switch 213 to open through the relay 214, so that the air pressure regulating valve 212 controls the set amount of gas in the air source to pass through the air pressure switch 213 and enter the cylinder body of the pushing cylinder 211, so that the lever of the pushing cylinder 211 pushes the mounting plate 22 and the wiping member 23 to synchronously approach the circumferential surface of the annealing copper wheel 12 until reaching the set position. At this time, the wiping member 23 conflicts with the circumferential surface of the annealing copper wheel 12, and the annealing copper wheel 12 continues to rotate under the drive of the motor, so that the wiping member 23 wipes the circumferential surface of the annealing copper wheel 12, removes oil stains / pits / deformation and other problems on the circumferential surface of the annealing copper wheel 12, and realizes automatic wiping of the annealing copper wheel 12. When the wiping reaches the set time, the time switch 24 controls the air pressure switch 213 to close through the relay 214, so that the push cylinder 211 drives the wiping member 23 away from the annealing copper wheel 12 and returns to the initial position.

[0035] In one example, two push cylinders 211 are provided. The two push cylinders 211 are first fixedly mounted on a mounting block 25, and then the mounting block 25 is fixedly mounted on the front of the vertical plate 11 by bolts, so as to facilitate the installation between the push cylinder 211 and the vertical plate 11. Specifically, the mounting block 25 is T-shaped, and the mounting block 25 includes a bottom plate portion 251 in the shape of a rectangular plate and a partition portion 252 in the shape of a rectangular plate which is vertically arranged in the middle of the bottom plate portion 251. The two push cylinders 211 are respectively located on both sides of the partition portion 252, and are both fixedly mounted on the bottom plate portion 251 by bolts. The mounting plate 22 is generally in the shape of a rectangular plate, and the cylinder rods of the two push cylinders 211 are respectively fixedly connected to both sides of the back of the mounting plate 22 along the length direction of the mounting plate 22, and the two push cylinders 211 synchronously push the mounting plate 22 to move, so as to ensure the stability of the movement of the mounting plate 22.

[0036] Furthermore, a plurality of guide posts 26 are fixedly provided on the back of the mounting plate 22, and guide holes 27 are provided on the partition plate 252, which are matched with the guide posts 26 one by one. When the push cylinder 211 pushes the mounting plate 22 to move, the guide posts 26 slide axially relative to the guide holes 27 in the guide holes 27, thereby further improving the stability of the movement of the mounting plate 22. In this embodiment, two guide posts 26 are provided, and the two guide posts 26 are provided in the middle of the mounting plate 22, and are respectively provided on both sides of the back of the mounting plate 22 along the width direction of the mounting plate 22. The axial directions of the guide posts 26 and the guide holes 27 are both provided along the radial direction of the annealing copper wheel 12.

[0037] In one example, an adapter 28 that is one-to-one compatible with the push cylinder 211 is also installed on the front side of the vertical plate 11. The cylinder drawn out from the air pressure switch 213 is connected to the adapter 28 and then to the corresponding push flagpole to change the position of the air pipe according to actual conditions to prevent the air pipe from interfering with the operation of various components on the tin coating annealing machine.

[0038] In one example, the wiping member 23 is a scouring pad, and the wiping member 23 is generally in the shape of a rectangular block. The length direction of the wiping member 23 is arranged along a tangent direction of the circumferential surface of the annealing copper wheel 12, and the width of the wiping member 23 is arranged along the axial direction of the annealing copper wheel 12. The wiping member 23 is clamped and fixed on the front of the mounting plate 22 by two baffles 29. Specifically, the two baffles 29 are respectively arranged on both sides of the mounting plate 22 along the length direction, and have a fixing portion 292291 installed on the side of the mounting plate 22 on the corresponding side by bolts and a clamping portion bent inwardly relative to the fixing portion 292291. The wiping member 23 is clamped and fixed between the two clamping portions of the two baffles 29, which is very convenient for replacing the wiping member 23. Preferably, the bending angle a of the clamping portion relative to the corresponding fixing portion 292291 is 5-30 degrees.

[0039] In one example, the annealing copper wheel 12 has an annular guide groove 13 on its circumferential surface, and the front side of the mounting plate 22 is integrally formed with a boss 30 corresponding to the guide groove 13. The boss 30 is located between the wiping member 23 and the front side of the mounting plate 22. During the wiping operation, the boss 30 can push the wiping member 23 partly into the guide groove 13 and fully contact the bottom surface of the guide groove 13, thereby fully wiping the bottom of the guide groove 13.

[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
