[0039] Each component of the above welding strip reel will be described below in combination with FIG. 1(a) and FIG. 1(b).

[0040] Specifically, the welding ribbon reel provided by the present invention includes a central axis structure. In this embodiment, as shown in the figure, the central axis structure includes an outer hollow shaft 100 and an inner hollow shaft 101, wherein the outer hollow shaft 100 is sleeved outside the inner hollow shaft 101 and the two are arranged coaxially.

[0048] The welding strip cutting device cuts the residual welding strip on the welding strip reel along the corresponding hollow opening;

[0049] The reel removal device removes the welding strip reel from the reel moving device after the residual welding strip is cut off.

[0050] The following will be combined Figure 2 And Figure 3 The components of the welding strip recovery equipment described above will be described.

[0051] Specifically, as Figure 2As shown, the welding strip recycling device provided by the utility model comprises a shell 200, a reel moving device, a reel rotating device, a welding strip cutting device and a reel removing device 208. The shell 200 comprises a containing space, and the reel moving device, the reel rotating device, the welding strip cutting device and the reel removing device 208 are all arranged in the containing space.

[0052] The reel moving device is used for driving the welding strip reel to move along a preset path in the containing space of the shell 200. In the embodiment, as shown in the figure, Figure 2 The reel moving device comprises a track 201, a driving structure and at least one reel mounting structure 202, wherein the driving structure comprises a driving wheel (not shown), a driven wheel (not shown) and a motor (not shown), the track 201 is sleeved on the driving wheel and the driven wheel, the motor drives the driving wheel to rotate, and all the reel mounting structures 202 are mounted on the track 201. When the welding strip recycling device works, the welding strip reel with residual welding strips is mounted on the reel mounting structure 202, the motor drives the driving wheel to rotate so as to drive the track 201 to rotate, the track 201 rotates so as to drive the reel mounting structure 202 to move and further drive the welding strip reel to move. In the embodiment, as shown in the figure, Figure 3 The reel mounting structure 202 comprises a mounting plate 2021, a connecting part 2022, a first mounting rod 2023 and at least one second mounting rod 2024. The mounting plate 2021 comprises two opposite surfaces, the connecting part 2022 is arranged on one surface of the mounting plate 2021, and the first mounting rod 2023 and the second mounting rod 2024 are arranged on the other surface of the mounting plate 2021. The reel mounting structure 202 is rotatably mounted on one side of the track 201 through the connecting part 2022. As to how to rotatably mount the reel mounting structure 202 on the track 201, the utility model does not make any limitation, for example, a bearing can be arranged between the connecting part 2022 and the track 201. When the number of the reel mounting structures 202 is more than one, all the reel mounting structures 202 are preferably mounted on the same side of the track 201 as shown in the figure. Figure 3 Figure 3 ​The side of the track 201 where the reel mounting structure 202 is located is defined as the first side of the track 201, and correspondingly, the other side of the track 201 is defined as the second side of the track 201. The first mounting rod 2023 and the second mounting rod 2024 are arranged on the mounting plate 2021 in a manner that the first mounting rod 2023 corresponds to the cavity of the inner hollow shaft 101 of the solder ribbon reel, and the second mounting rod 2024 corresponds to the same number of through holes 103 on the end face of the solder ribbon reel. In this way, the solder ribbon reel can be mounted on the reel mounting structure 202 through the first mounting rod 2023 and the second mounting rod 2024, wherein the first mounting rod 2023 is inserted into the cavity of the inner hollow shaft 101 of the solder ribbon reel, and the second mounting rod 2023 is inserted into the through hole 103 on the end face of the solder ribbon reel corresponding thereto. The cooperation of the first mounting rod 2023 and the second mounting rod 2024 can effectively prevent the solder ribbon reel from running off and rotating during movement.

[0053] The reel rotating device is used to rotate the solder ribbon reel so that one hollow opening on the blocking part 104 corresponds to the solder ribbon cutting device after the solder ribbon reel is moved to the first position on the preset path by the reel moving device. The reel rotating device includes a reel rotating structure (not shown), an opening identifying structure, and a reel fixing structure. When the solder ribbon reel is moved to the first position on the preset path by the reel moving device, first, the reel moving device stops running so that the solder ribbon reel stops at the first position, then the reel rotating structure drives the reel mounting structure to rotate and in turn drives the solder ribbon reel to rotate, in the process of rotating the solder ribbon reel, the opening identifying structure identifies the hollow openings on the blocking part 104, and when one hollow opening on the blocking part 104 is identified to face the solder ribbon cutting device, the reel rotating structure is triggered to stop working and the reel fixing structure is triggered to fix the solder ribbon reel. In this embodiment, the reel rotating structure is realized by a retractable rotary manipulator, which is arranged at a position corresponding to the first position (2) on the second side of the track 201, when the solder ribbon reel 10 moves to the first position 2, the rotary manipulator extends to drive the connecting part 2022 in the reel mounting structure 202 to rotate, thereby driving the entire reel mounting structure 202 to rotate, and in turn driving the solder ribbon reel 10 to rotate. In this embodiment, as shown in Figure 2 Figure 2 and Figure 3 ​As shown, the opening recognition device is implemented by an infrared recognizer 204, which is arranged right above the first position 2 and can recognize the hollow opening facing right above. In this case, when the infrared recognizer 204 recognizes that a hollow opening 105 in the solder strip reel 10 extends to the part on the blocking part 104, it indicates that the hollow opening 105 is just facing right above, at this time, the infrared recognizer 204 triggers the rotary manipulator to stop working and triggers the reel fixing structure to fix the solder strip reel 10. In this embodiment, the reel fixing structure is implemented by a telescopic rod 205 (hereinafter referred to as the first telescopic rod 205), which is arranged on the first side of the track 201 and corresponds to the first position 2. When the infrared recognizer 204 recognizes that a hollow opening 105 on the blocking part 104 faces right above, the first telescopic rod 205 extends until it abuts against the solder strip reel 10 to fix it, which prevents the center shaft structure of the solder strip reel 10 from moving forward and backward during the cutting of the residual solder strip. It should be noted that (1) those skilled in the art can understand that the reel rotating device should not be limited to the rotary manipulator, any device that can directly or indirectly drive the rotation of the solder strip reel is suitable for the reel rotating device of the present application. For the sake of simplicity, all possible reel rotating devices are not listed here. Similarly, the opening recognition device should not be limited to the infrared recognizer, any device that can recognize the hollow opening (such as a camera, a photographic device, etc.) is suitable for the opening recognition device of the present application; the reel fixing structure should not be limited to the telescopic rod, any device that can fix the solder strip reel is suitable for the reel fixing structure of the present application; (2) using the infrared recognizer to recognize the hollow opening is a common technical means in the art, for the sake of simplicity, how the infrared recognizer recognizes the hollow opening is not described here; (3) after the cutting of the residual solder strip is completed, the rotary manipulator is retracted, and similarly, the first telescopic rod is retracted to release the fixation of the solder strip reel.

[0054] The solder strip cutting device is used to cut the residual solder strip on the solder strip reel along the hollow opening. In this embodiment, as shown in FIG. 2, the solder strip cutting device is implemented by a cutting device 202, which is arranged on the first position 2 and can cut the residual solder strip on the solder strip reel 10 along the hollow opening 105. In this embodiment, the cutting device 202 is implemented by a laser cutting device, which is arranged on the first position 2 and can cut the residual solder strip on the solder strip reel 10 along the hollow opening 105. It should be noted that (1) those skilled in the art can understand that the cutting device should not be limited to the laser cutting device, any device that can cut the residual solder strip on the solder strip reel along the hollow opening is suitable for the cutting device of the present application. For the sake of simplicity, all possible cutting devices are not listed here; (2) the laser cutting device is a common technical means in the art, for the sake of simplicity, how the laser cutting device cuts the residual solder strip is not described here. Figure 2 and Figure 3As shown, the ribbon cutting device includes a guillotine 206 and a robotic arm 207. The guillotine 206 is positioned directly above the first position 2 and is configured such that when the ribbon reel 10 moves to the first position 2 and the opening recognition structure identifies a hollow opening 105 on the ribbon reel 10 as facing upward, the cutting edge of the guillotine 206 precisely aligns with the hollow opening 105 on the ribbon reel 10 facing upward. The robotic arm 207 is connected to the guillotine 206. When the ribbon reel 10 moves to the first position 2 and the opening recognition structure identifies a hollow opening 105 on the ribbon reel 10 as facing upward, the robotic arm 207 drives the guillotine 206 downward to cut the remaining ribbon on the ribbon reel 10 along the upward-facing hollow opening. After the guillotine 206 completes cutting the remaining ribbon, the robotic arm 207 drives the guillotine 206 upward.

[0055] The reel removal device is used to remove the soldering ribbon reel from the reel moving device after the residual soldering ribbon is cut off. Specifically, after the residual soldering ribbon on the soldering ribbon reel is cut off, the reel moving device drives the soldering ribbon reel to continue moving along the preset path. When the soldering ribbon reel moves to the second position, the reel moving device stops so that the soldering ribbon reel stops at the second position, and the reel removal device starts working to remove the soldering ribbon reel from the reel moving device. In this embodiment, if Figure 2 and Figure 3 As shown, the reel removal device adopts a telescopic rod 208 (hereinafter referred to as the second telescopic rod 208), which is arranged on one side of the reel moving device (in this embodiment, the second side of the crawler 201) and is connected to the second position ( Figure 2 When the cut ribbon reel 10 moves to the second position 3, the second telescopic rod 208 extends to push the ribbon reel 10 off the reel moving device (specifically, the reel mounting structure 202), and the second telescopic rod 208 retracts after the ribbon reel 10 is off the reel mounting structure 202. It will be appreciated by those skilled in the art that the reel removal device is not limited to the second telescopic rod. Any device that can remove the ribbon reel from the reel mounting structure is applicable to the reel removal device of the present invention. For the sake of simplicity, all possible reel removal devices are not listed here one by one.
