Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic welding tapes, in particular to an automatic shaft alignment device for shaft-mounted welding tape spools. Background Art

[0002] The fully automatic tin plating machine for welding tapes in the solar photovoltaic industry is mainly used for the production of photovoltaic welding tapes. Photovoltaic welding tapes, also known as tin-plated copper tapes or tin-coated copper tapes, are divided into bus bars and interconnection bars, and are used for connecting between battery cells of photovoltaic modules, playing an important role in conducting and collecting electricity. Welding tapes are important raw materials in the welding process of photovoltaic modules. The quality of welding tapes will directly affect the current collection efficiency of photovoltaic modules and has a great impact on the power of photovoltaic modules.

[0003] When the existing fully automatic tin plating machine performs the operation of loading an empty spool onto the shaft, there is no automatic shaft alignment process. The empty spool is directly sent to a preset station; or the shaft is aligned manually by workers, and then the empty spool is clamped by a clamping device. The existing operation methods have the following main disadvantages:

[0004] (1) The quality of wire arrangement cannot be guaranteed: The welding tape is directly wound on the spool without shaft alignment. The relative position between the initial winding position of the welding tape and the process hole of the spool cannot be guaranteed. The head of the welding tape cannot be stably fixed in the process hole of the spool. When the welding tape is used to the bottom few layers, the unfixed head of the welding tape will cause the tightened welding tape to become loose, affecting the final use effect.

[0005] (2) High labor intensity: The production speed of a single roll of welding tape is one spool every 40 - 80 minutes. When all the fully automatic tin plating machines in the production workshop are working, about 1200 - 1500 rolls of shaft-mounted welding tapes are produced daily. The operators need to complete the shaft alignment of the spools hundreds of times a day, with a high labor frequency and a large labor intensity.

[0006] (3) High error rate: Since the operation of loading the shaft and aligning the shaft is mainly manual and is greatly affected by human factors, if the alignment of the process hole position is incorrect, the situation where the head of the welding tape cannot be fixed will occur.

[0007] (4) High risk factor: The operation method of manually aligning the shaft requires the operator to be in close contact with the take-up reel and the locking device, which has a certain degree of danger. Summary of the Utility Model

[0008] According to the above technical problems to be solved, an automatic shaft alignment device for shaft-mounted welding tape spools is provided.

[0009] To achieve the above object, in a preferred embodiment, the utility model is configured to include a fully automatic coiling machine for photovoltaic solder tapes. A tape winding unit is arranged on the side of the fully automatic coiling machine for photovoltaic solder tapes to wind the solder tapes around an I-shaped spool. A spool storage rack is arranged directly below the tape winding unit, and an automatic loading and unloading module is arranged at the tail end of the spool storage rack for sending an empty spool to the tape winding unit.

[0010] In a preferred embodiment, the utility model can be further configured such that a rotating countershaft runner is arranged at the tail end of the spool storage rack, and the runner body of the countershaft runner protrudes and abuts against the I-shaped spool.

[0011] In a preferred embodiment, the utility model can be further configured such that an empty shaft detection sensor is arranged on the countershaft runner, and the empty shaft detection sensor is electrically connected to the countershaft runner to transmit signals.

[0012] In a preferred embodiment, the utility model can be further configured such that a laser shaft aligner is arranged on the side of the countershaft runner, and the laser shaft aligner is electrically connected to the countershaft runner to transmit signals.

[0013] In a preferred embodiment, the utility model can be further configured such that a limiting gate plate is arranged between the tail end of the spool storage rack and the automatic loading and unloading module. The limiting gate plate is controlled by an electric telescopic cylinder, and the electric telescopic cylinder is electrically connected to the empty shaft detection sensor to transmit signals.

[0014] In a preferred embodiment, the utility model can be further configured such that the automatic loading and unloading module includes a support table, the support table is connected to a side lifting rail, and the countershaft runner, the laser shaft aligner and the empty shaft detection sensor are all arranged on the support table.

[0015] Beneficial effects: The automatic shaft-aligning device for shaft-mounted soldering tape spools of the present utility model improves the stability of winding and wire laying. Each time a new spool is replaced, the relative positions of the wire clamping device and the small holes on the spool always remain unchanged, ensuring that the solder tape head at the bottom of the spool is always fixed in the small holes of the spool, and ensuring stable and tight wire laying at the bottom of the solder tape. It reduces labor intensity. Only the spools need to be replenished regularly, and the rest of the operations such as automatic shaft replacement, blanking, shaft loading, shaft alignment, and locking can be automatically completed by the system. In this way, the operators can be avoided from frequently replacing and aligning the shafts, greatly reducing the labor intensity of the operators. It reduces the error rate and improves the passing rate of product quality inspection and packaging: The blanking, shaft loading, shaft alignment, and locking of the shaft-mounted soldering tape are all automated, thus greatly reducing human factors, reducing the error rate, and improving the passing rate of solder tape production. It reduces the risk coefficient during the production operation process: After adding the automatic shaft-aligning system, only the spools need to be replenished regularly, and the shaft-mounted soldering tape produced on the material trolley needs to be sent for inspection regularly; the operators do not need to directly contact the winding shaft and the locking device manually, greatly reducing the risk of injury to the operators caused by the winding shaft and the locking device during the production process; It reduces labor costs: After adding the automatic shaft-aligning system, only the spools need to be replenished regularly, and the shaft replacement, blanking, shaft loading, shaft alignment, and locking do not require personnel to participate. Only a single operator needs to conduct regular inspections, greatly reducing the number of operators and labor costs. Brief Description of the Drawings

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-3As shown in the figure, an automatic shaft-aligning device for shaft-mounted welding tape spools includes a fully automatic photovoltaic welding tape rewinding machine. A tape winding unit is arranged on the side of the fully automatic photovoltaic welding tape rewinding machine to wind the welding tape onto the spool. A spool storage rack is arranged directly below the tape winding unit. An automatic loading and unloading module is arranged at the end of the spool storage rack to send empty spools to the tape winding unit. The fully automatic photovoltaic welding tape rewinding machine is mainly used to wind the photovoltaic welding tape onto the spool to generate shaft-mounted welding tape. The empty shaft detection sensor is mainly used to detect whether the spool reaches the preset position. The laser shaft-aligning device is mainly used to detect the marked points on the spool. The shaft-aligning rotating device is mainly used to rotate and position the spool. If the marked point on the spool is not at the set position, the shaft-aligning rotating device rotates the spool in the preset direction until the marked point on the spool reaches the preset position. The automatic loading and unloading module is mainly used to pick up and unload the full-axis welding tape and load the empty-axis spool.

[0023] A rotating shaft-aligning wheel 4 is arranged at the end of the spool storage rack. The wheel body of the shaft-aligning wheel 4 protrudes and abuts against the spool 6. After receiving the signal that the shaft-mounted welding tape has been transferred in place, the automatic loading and unloading system delivers the spool to the shaft-aligning rotating device.

[0024] An empty shaft detection sensor 2 is arranged on the shaft-aligning wheel 4. The empty shaft detection sensor 2 is electrically connected to the shaft-aligning wheel 4 to transmit signals, and it is judged whether to start the shaft-aligning wheel 4 through the signals of the sensor.

[0025] A laser shaft-aligner 3 is arranged on the side of the shaft-aligning wheel 4. The laser shaft-aligner 3 is electrically connected to the shaft-aligning wheel 4 to transmit signals.

[0026] A limiting gate is arranged between the end of the spool storage rack and the automatic loading and unloading module 5. The limiting gate is controlled by an electric telescopic cylinder, and the electric telescopic cylinder is electrically connected to the empty shaft detection sensor 2 to transmit signals to prevent the arranged spools from squeezing forward.

[0027] The automatic loading and unloading module 5 includes a support table. The support table is connected to the lifting rail on the side. The shaft-aligning wheel 4, the laser shaft-aligner 3 and the empty shaft detection sensor 2 are all placed on the support table.

[0028] When the automatic shaft-aligning system for soldering tapes starts to work, after the fully automatic winding machine 1 for photovoltaic soldering tapes winds the photovoltaic soldering tapes around the spool 6 to generate a full spool of soldering tapes, the automatic unloading system of the fully automatic winding machine 1 for photovoltaic soldering tapes transfers the full spool of soldering tapes to the material trolley; after receiving the signal that the shaft-mounted soldering tapes are transferred in place, the automatic loading and unloading system delivers the spool 6 to the shaft-aligning rotating wheel 4; after the empty spool detection sensor 2 detects that the spool 6 reaches the preset working position, it sends a feedback signal to the system; after receiving the feedback signal, the system controls the shaft-aligning rotating wheel 4 to rotate, driving the spool 6 to rotate in the preset direction; at the same time, the laser shaft-aligner 3 detects the marking point of the spool 6. When the marking point is not detected, the shaft-aligning rotating wheel 4 will keep rotating until the laser shaft-aligner 3 detects the marking point of the spool 6 and then stops rotating; then, after receiving the signal fed back by the laser shaft-aligner 3, the system controls the automatic loading and unloading module 5 to lift the spool 6; after the spool 6 rises to the preset working position, the clamping device of the fully automatic winding machine 1 for photovoltaic soldering tapes clamps the spool 6, and then the automatic loading and unloading module 5 descends to the initial working position, thus completing the whole process of the automatic shaft-aligning and loading operation.
