[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example

[0051] In a preferred embodiment, Figure 1 As shown, a double-grip arm winder includes a base 1. The base 1 is welded with structural parts to ensure that the base 1 has sufficient mechanical strength and is convenient for the production and installation of the double-grip arm automatic winder. A long guide rail moving pair 7 is welded on the base 1. The long guide rail moving pair 7 has good flatness and straightness through welding processing technology to ensure smooth movement on the long guide rail moving pair 7. The long guide rail moving pair 7 can adopt a double guide rail design, and the length can be set to 2.6m. At the same time, in order to meet the production needs in different scenarios, different lengths of long guide rail moving pairs 7 can be selected. The length of the long guide rail moving pair 7 should match the length of the base 1. A wire arrangement mechanism 6 is set on the base 1, such as Figure 8As shown, the wire arrangement mechanism 6 includes a central mechanism 6-1, a stretching rod 6-2 and a fixed plate 6-3. The central mechanism 6-1 is connected to the stretching rod 6-2, and the stretching rod 6-2 is fixed on the fixed plate 6-3. The microchannel aluminum flat tube is different from cables and other solid aluminum flat bars. The wire arrangement speed needs to be perfectly matched with the speed of the production line to achieve the effect of uniform, non-deformed and non-loose wire arrangement, thereby improving the yield rate. The wire arrangement mechanism 6 can fully and effectively utilize the space of the equipment. The wire arrangement mechanism 6 can not only ensure that the wire arrangement speed of the microchannel aluminum flat tube meets the production needs, but also ensure that the damaged parts on the equipment can be quickly replaced. The length of the stretching rod 6-2 can be set to 1150mm, and the width can be set to 150mm. For bases 1 of different sizes, wire arrangement mechanisms 6 of different lengths and widths can be set. The use of metal materials for the wire arrangement mechanism 6 can ensure that the wire arrangement mechanism 6 has sufficient strength and is not easily deformed during use.

[0052] The left moving subassembly 2 and the right moving subassembly 3 are respectively arranged on both sides of the base 1, and the left moving subassembly 2 and the right moving subassembly 3 are fixed on the base 1 through a mounting seat and a bearing seat, wherein the left moving subassembly 2 and the right moving subassembly 3 are provided with a mounting plate, and the mounting plate supports and fixes various components on the left moving subassembly 2 and the right moving subassembly 3. The left moving subassembly 2 includes a left chuck 2-1, a cylinder 2-3 and a positioning square pin 2-2, as shown in FIG. Figure 3 and Figure 4 As shown, the left moving subassembly 2 is repeatedly positioned by the cylinder 2-3 and the positioning square pin 2-2, which serves as the loading reference of the wireless crane. The left chuck 2-1 is located at the top of the left moving subassembly 2, and the cylinder 2-3 is located on the outside of the left moving subassembly 2. The movement and positioning of the left moving subassembly 2 are achieved by the cylinder 2-3. A positioning square pin 2-2 is set under the left chuck 2-1. The cylinder 2-3 is used to push the left chuck 2-1 to a fixed position, and the positioning square pin 2-2 is inserted into the positioning pin. The positioning square pin 2-1 is designed to have an adjustable stroke of 0-7.5mm. In order to avoid the dimensional tolerance of the empty material roll, the square pin 2-2-2 is designed as a square pin, as shown in FIG. Figure 5As shown, considering the thickness, direction and compact position, the insertion and extraction operations of the square pin 2-2-2 are driven by the first double-rod cylinder 2-2-1. Compared with the ordinary cylinder, the first double-rod cylinder 2-2-1 has twice the output force under the condition of ensuring that the cylinder thickness remains unchanged. The right moving sub-group 3 includes the right clamp 3-1, the curling servo mechanism 3-2 and the micro motor 3-3. The right moving sub-group 3 completes the positioning and clamping of the empty material roll through the micro motor 3-3, right side. For the processing of microchannel aluminum tubes, the first thing to do is to load the materials. After loading is completed, the sensor installed on the right moving subassembly 3 sends a signal that loading is completed, and the automatic loading head equipment starts to squeeze and start, and the aluminum flat tube extruded by the extruder is sent into the opening of the empty material tray. After the curling servo motor 3-2 receives the signal from the sensor, the empty material tray starts, and the curling servo motor 3-2 starts to reel in. The inner diameter of the reel is 500mm and the width is 700mm; the maximum winding diameter is 1150mm; the weight of the coil is 650-800kg / roll. After the material is reeled in, the automatic head and tail equipment starts to trim the tail, bend the tail and stick it to the side wall of the coil to complete the curling. After completing the above steps, start the unloading component 5, such as Figure 7 As shown, the unloading assembly 5 includes a second double-rod cylinder 5-2 and a support block 5-1. The second double-rod cylinder 5-2 is arranged on the base 1, and the support block 5-1 is arranged on the second double-rod cylinder 5-2. The distance of the support block 5-1 can be adjusted. By starting the second double-rod cylinder 5-2, the full roll is lifted, the left moving subassembly 2 and the right moving subassembly 3 retreat 100mm, and the roll falls on the support block 5-1. When the second double-rod cylinder 5-2 descends, the roll automatically falls on the unloading inclined plate, and rolls to the unloading rack by gravity. The full roll is transferred to the finished product warehouse by the wireless crane. The next round of empty roll starts, and the second rewinding begins.

[0053] In the embodiment, a pneumatic tension structure is used as the tension mechanism of the device to replace the traditional technology using a heavy object as the tension mechanism, such as Fig. 9 As shown, the tensioning force of the pneumatic tension structure can be set according to the specifications of the aluminum flat tube, so that the constant tension mechanism helps to roll tightly, maintain stability, and not loosen. The embodiment also includes a terminal operating table 4. The structure and installation of the terminal operating table 4 can refer to the relevant existing technology. The terminal operating table 4 includes a servo drive, a drive module, a motion controller, a sensor module, a power module, a low-voltage electrical component and a human-machine interface. The servo drive and the drive realize accurate control of the equipment to ensure the fluency and accuracy of the setting operation; the sensor module realizes accurate transmission of the status information of the equipment to ensure the fluency of the entire work; the power module supplies energy to the entire equipment; the low-voltage electrical components provide guarantees for the signal transmission and current transmission of the equipment to ensure that the equipment has good fluency; the operator can operate and set the equipment through the human-machine interface.

[0054] The technical content in this embodiment is only for the operation of automatically raising the empty roll and lowering the full roll of the wireless crane. For other equipment and methods used in the production process of microchannel aluminum flat tubes, reference can be made to existing related technologies.

[0055] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
