[0026] Example

[0027] Reference Figure 1-4An automatic disassembly device for threaded inserts includes a base 10, on which a positioning module 20 and a disassembly module 30 are mounted. The positioning module 20 includes a positioning plate 21, with a positioning block 211 in the middle of the positioning plate 21. Clamping cylinders 212 are mounted opposite each other at both ends of the positioning plate 21. Clamping blocks 213 are mounted on the piston rods of the clamping cylinders 212. In use, a robotic arm takes out the product from the injection mold and places it on the positioning block 211. The positioning block has a positioning groove for positioning the product. Then, the clamping cylinders 212 at both ends are controlled to push the clamping blocks 213 to clamp the product, thus fixing the product.

[0028] Reference Figure 1-4 A sliding mechanism is provided at the bottom of the positioning plate 21 on the base. The sliding mechanism includes a sliding cylinder 22 and a first slide rail 23. The positioning plate 21 is installed on the first slide rail 23. The piston rod of the sliding cylinder 22 is connected to the positioning plate 21. The sliding cylinder 22 pushes the slider to move. When it is necessary to remove the threaded insert 41, the sliding cylinder 22 pushes the positioning plate 21 to be placed between the two wrenches. When the robot arm wants to remove the threaded insert 41, it controls the sliding cylinder 22 to move away to prevent the positioning plate 21 from interfering with the robot arm's picking.

[0029] Reference Figure 1-3 , Figure 5 The disassembly module 30 includes a wrench and a drive motor 31. The drive motor 31 drives the wrench to rotate. The drive motor 31 and the wrench are movably arranged on both sides of the positioning plate 21 along its length. Specifically, a first wrench 33 and a second wrench 34 are respectively arranged on both sides of the positioning plate 21. The second wrench 34 is located below the first wrench 33. The first wrench 33 and the second wrench 34 on both sides are respectively positioned for two threaded inserts 41 at both ends of the product. The wrench extends into the internal hexagonal groove of the threaded insert 41. By rotating the first wrench 33 and the second wrench 34, the threaded insert 41 is rotated and removed from the product.

[0030] Reference Figure 1-3 , Figure 5 The disassembly module 30 further includes a gear set 32, which connects to a drive motor 31 and a wrench. The gear set 32 ​​includes a housing, inside which are arranged a drive gear 321, an intermediate gear 322, and a driven gear 323. A first wrench 33 is mounted on the drive gear 321, and a second wrench 34 is mounted on the driven gear 323. The drive motor 31 drives the drive gear 321 to rotate, which in turn drives the first wrench 33 to rotate. Simultaneously, the drive gear 321 drives the driven gear 323 to rotate via the intermediate gear 322, which in turn drives the second wrench 34 to rotate. This rotation of the first wrench 33 and the second wrench 34 causes the threaded insert 41 to rotate and exit from the product, thus achieving automatic disassembly of the threaded insert 41 and improving work efficiency.

[0031] Reference Figure 1-3 , Figure 5 The disassembly module 30 also includes a second slide rail 35, on which a gear set 32 ​​is mounted. A cylinder is mounted on the second slide rail 35, controlling the cylinder to push the gear set 32 ​​and the wrench closer to or away from the clamped product. Specifically, the wrench is controlled to insert into the threaded insert 41 while rotating, and simultaneously the wrench moves away from the product along the second slide rail 35. Furthermore, a position sensor 36 is provided on one side of the second slide rail 35, limiting the wrench's movement along the second slide rail 35 to two extreme positions.

[0032] Reference Figure 2 A protective cover 11 is further provided on the base, and an operation panel is provided on the panel of the protective cover 11, so that the operator can control the operation of the equipment on the operation panel. The protective cover 11 plays a role in protecting the operator during installation.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
