Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please see Figure 1-4 The present invention provides the following technical solution: an automatic alignment device for a supercapacitor winding machine, comprising a support substrate 1, a tension adjusting base 2 provided at one end of one side of the support substrate 1, a guide and correction mechanism 3 provided above the tension adjusting base 2, a winding mechanism 5 provided at the other end of one side of the support substrate 1, a drive mechanism 6 provided at one end of the winding mechanism 5, an adjusting component 4 provided on one side of the tension adjusting base 2, a connecting plate 7 provided above the adjusting component 4, a disassembly and assembly component 8 provided above the connecting plate 7, and a laser sensor 9 provided above the disassembly and assembly component 8.
[0023] Specifically, the adjustment assembly 4 includes an adjustment seat 41, a dual-axis motor 42, an adjustment trapezoidal lead screw 43, a square slide plate 44, and a dust cover 45. The adjustment seat 41 is fixedly connected to one side of the tension adjustment base 2. The dual-axis motor 42 is fixedly connected to the middle of the adjustment seat 41. The two ends of the dual-axis motor 42 are fixedly connected to the adjustment trapezoidal lead screw 43. The adjustment trapezoidal lead screw 43 and the adjustment seat 41 are rotatably connected by bearings. The square slide plate 44 is threadedly connected to the surface of the adjustment trapezoidal lead screw 43. The dust cover 45 is installed in the middle of the top of the adjustment seat 41. The square slide plate 44 and the adjustment seat 41 are in close sliding connection. The top of the square slide plate 44 is in close sliding connection with the dust cover 45. One end of the top of the square slide plate 44 is fixedly connected to the connecting plate 7.
[0024] By adopting the above technical solution, the dual-axis motor 42 is started, which drives the adjusting trapezoidal lead screw 43 to rotate. The rotation of the adjusting trapezoidal lead screw 43 will drive the square slide plate 44 to move. The movement of the square slide plate 44 will drive the connecting plate 7 to move, thereby driving the laser sensor 9 to move for position adjustment. The dust cover 45 is convenient for protecting the top of the adjusting trapezoidal lead screw 43 and preventing it from being corroded by dust.
[0025] Specifically, the dust cover 45 is equipped with mounting screws 46 at both ends, and the adjusting seat 41 has threaded holes at both ends that mate with the mounting screws 46.
[0026] By adopting the above technical solution, the mounting screw 46 and the threaded hole are matched, which facilitates the disassembly and assembly of the dust cover 45, and facilitates the maintenance of the adjusting trapezoidal lead screw 43.
[0027] Specifically, positioning rods 47 are symmetrically and fixedly connected to both ends below the dust cover 45, and positioning holes that cooperate with the positioning rods 47 are opened on both sides above the adjusting seat 41.
[0028] By adopting the above technical solution, the positioning rod 47 and the positioning hole facilitate the positioning and installation of the dust cover 45.
[0029] In this embodiment, when in use: the dual-axis motor 42 is started, which drives the adjusting trapezoidal lead screw 43 to rotate. The rotation of the adjusting trapezoidal lead screw 43 causes the square slide plate 44 to move, which in turn causes the connecting plate 7 to move, thereby moving the laser sensor 9 to adjust its position. The dust cover 45 protects the top of the adjusting trapezoidal lead screw 43 from dust corrosion. The mounting screw 46 and threaded hole are engaged to facilitate the disassembly and assembly of the dust cover 45, which is convenient for the maintenance of the adjusting trapezoidal lead screw 43. This allows the device to easily drive the laser sensor 9 for adjustment during use, and the structure is practical.
[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that, specifically, the disassembly and assembly component 8 includes a disassembly and assembly base 81, a square insert 82, a fixing rod 83, a pull block 84, a fixing spring 85, and a handle 86. The disassembly and assembly base 81 is fixedly connected to the top of the connecting plate 7. The square insert 82 is tightly inserted into the top of the disassembly and assembly base 81. The fixing rod 83 is tightly inserted into one side of the square insert 82. The fixing rod 83 and the disassembly and assembly base 81 are slidably connected. The pull block 84 is fixedly connected to one side of the fixing rod 83. The two ends of one side of the pull block 84 are symmetrically connected to the fixing spring 85. The fixing spring 85 and the disassembly and assembly base 81 are fixedly connected. The handle 86 is fixedly connected to the other side of the pull block 84.
[0032] By adopting the above technical solution, by pulling the handle 86, the handle 86 drives the pull block 84 to move, and the pull block 84 moves to stretch the fixing spring 85, so that the fixing rod 83 disengages from the fixing hole on one side of the square insert 82. Then, the laser sensor 9 can be removed for inspection and maintenance by separating the square insert 82 and the disassembly base 81.
[0033] Specifically, a fixing hole is provided on one side of the square insert 82 to be tightly inserted into the fixing rod 83.
[0034] By adopting the above technical solution, the fixing hole facilitates the insertion of the fixing rod 83 to fix the square insert block 82.
[0035] In this embodiment, when in use: by pulling the handle 86, the handle 86 drives the pull block 84 to move, and the pull block 84 moves to stretch the fixing spring 85, so that the fixing rod 83 disengages from the fixing hole on one side of the square insert 82. Then, the laser sensor 9 can be removed for inspection and maintenance by separating the square insert 82 and the disassembly base 81.
[0036] The structure and operating principle of the bearing substrate 1, tension adjusting base 2, guiding and correcting mechanism 3, winding mechanism 5, driving mechanism 6, and laser sensor 9 in this utility model have been disclosed in a capacitor winding device based on tension adjusting and correcting function disclosed in Chinese patent application number 202520264064.6. Its working principle is as follows: the tension adjusting base 2 includes a bearing platform, bearing seat, first mounting plate, second mounting plate, reinforcing plate, first reducer, and servo motor; the guiding and correcting mechanism 3 includes a rectangular frame, lower roller shaft, and hydraulic cylinder. The system includes an upper roller frame, upper pressure roller, guide groove, guide rod, and drive shaft; the winding mechanism 5 includes an inner winding reel, winding shaft, outer winding reel, locking seat, handwheel, and lead screw; the drive mechanism 6 includes a second reducer and an asynchronous motor; in use, the aluminum foil roll is loaded into the unwinding machine, which operates under the drive of the motor, rotating the unwinding shaft to release the aluminum foil strip. After processing, the released aluminum foil strip extends around the guide and correction mechanism 3 into the winding mechanism 5. Under the transmission action of the drive mechanism 6, the winding shaft inside the winding mechanism 5 rotates, realizing the winding of the capacitor aluminum foil. During normal winding... The aluminum foil strip is located on the surface of the upper pressure roller of the guide and correction mechanism 3, and the upper roller frame extends under the action of the hydraulic cylinder to contact the upper surface of the aluminum foil on the upper pressure roller, thereby achieving the effect of guiding and applying pressure and preventing the aluminum foil from shifting to a certain extent. During the process, the laser sensor 9 detects the position of the aluminum foil. Under normal conditions, the laser beam emitted by the laser sensor 9 is unobstructed, which means that no shift has occurred. When the aluminum foil strip shifts to one side, it will touch and cover the laser beam emitted by the laser sensor 9 on one side. This means that the aluminum foil strip has shifted to the side of the blocked sensor. After the laser sensor 9 is blocked, it feeds back a signal to the controller, which drives the hydraulic cylinder to move upward and stops the pressure of the upper pressure roller. The servo motor in the tension adjustment base 2 controls the guide and correction mechanism 3 to deflect to the other side of the shift. The deflection angle does not exceed ten degrees. At this time, the tension of the contact surface between the aluminum foil and the lower roller shaft changes. The friction on one side is greater than that on the other side, so the aluminum foil shifts to the side with greater friction and resets, achieving the correction effect. After the correction is completed, the guide and correction mechanism 3 and the hydraulic cylinder reset and resume guiding the aluminum foil strip. The whole process does not require stopping the machine.
[0037] The working principle and usage process of this utility model: This utility model is used in the production of supercapacitors for the winding of aluminum foil. In use, the aluminum foil roll is loaded into an unwinding machine, which operates under the drive of a motor. The unwinding machine rotates the unwinding shaft to release the aluminum foil strip. After processing, the released aluminum foil strip extends around the guide and correction mechanism 3 into the winding mechanism 5. Under the transmission action of the drive mechanism 6, the winding shaft inside the winding mechanism 5 rotates, realizing the winding of the capacitor aluminum foil. During normal winding, the aluminum foil strip is located on the surface of the upper pressure roller of the guide and correction mechanism 3, and the upper roller frame extends under the action of a hydraulic cylinder, contacting the upper surface of the aluminum foil on the upper pressure roller, achieving a guiding and pressure effect, and to a certain extent avoiding aluminum foil... During foil offset, laser sensor 9 detects the position of the aluminum foil. Under normal conditions, the laser beam emitted by laser sensor 9 is unobstructed, indicating no offset. However, when the aluminum foil shifts to one side, it touches and covers the laser beam emitted by one side of laser sensor 9. This indicates that the aluminum foil has shifted towards the side of the blocked sensor. After being blocked, laser sensor 9 sends a feedback signal to the controller, which drives the hydraulic cylinder to move upward, stopping the upper pressure roller from applying pressure. The servo motor in the tension adjustment base 2 then controls the guide correction mechanism 3 to deflect to the other side of the offset, with a deflection angle not exceeding ten degrees. At this time, the tension of the contact surface between the aluminum foil and the lower roller changes, and one side... When the friction force is greater on one side than the other, the device shifts and resets towards the side with greater friction, achieving a correction effect. After correction, the guide correction mechanism 3 and hydraulic cylinder reset, re-guiding the aluminum foil strip. The entire process requires no machine downtime. The adjustment component 4 facilitates position adjustment of the laser sensor 9 according to the aluminum foil size, and the disassembly and assembly component 8 facilitates disassembly, assembly, inspection, and maintenance of the laser sensor 9. When using the adjustment component 4, the dual-axis motor 42 is started, which drives the adjusting trapezoidal lead screw 43 to rotate. The rotation of the adjusting trapezoidal lead screw 43 moves the square slide plate 44, which in turn moves the connecting plate 7, thereby moving the laser sensor 9 to perform positioning. The dust cover 45 is used to protect the upper part of the adjusting trapezoidal lead screw 43 from dust corrosion. The mounting screw 46 and threaded hole are matched to facilitate the disassembly and assembly of the dust cover 45, which is convenient for the maintenance of the adjusting trapezoidal lead screw 43. This allows the device to easily drive the laser sensor 9 for adjustment during use. The structure is practical. When using the disassembly and assembly component 8, by pulling the handle 86, the handle 86 drives the pull block 84 to move. The movement of the pull block 84 stretches the fixing spring 85, causing the fixing rod 83 to disengage from the fixing hole on one side of the square insert 82. Then, the laser sensor 9 can be removed for inspection and maintenance by separating the square insert 82 from the disassembly and assembly base 81.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
