Description

Technical Field

[0001] This utility model relates to the field of intelligent assembly, and in particular to an intelligent assembly workstation device with a quick-change gripper. Background Technology

[0002] In the current field of automated assembly, mechanical grippers need to be frequently adapted to workpieces of different specifications, leading to increasingly higher requirements for gripper change efficiency and assembly precision. Existing assembly workstations often employ a single adjustment structure or rely on manually pushing moving parts, which is prone to gripper misalignment due to adjustment deviations, affecting assembly quality. The fixing method is often a single-point locking, which is prone to loosening during high-frequency operations, increasing equipment operational risks. Furthermore, changing grippers requires disassembling the main components of the device, a cumbersome and time-consuming process that fails to meet the high-efficiency changeover requirements of production lines, thus hindering the overall efficiency of automated assembly. Therefore, there is an urgent need for an assembly workstation device that combines precise adjustment, stable fixing, and rapid gripper change capabilities.

[0003] While existing technologies can achieve certain assembly effects, they suffer from several drawbacks: the lack of a precise adjustment mechanism makes clamping deviations easy to occur, and the double fixing guarantee leads to loosening of the fixing. Changing the gripper requires disassembling the main component, resulting in low efficiency. In view of this, we propose an intelligent assembly station device with a quick-change gripper, which solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an intelligent assembly station device with a quick-change gripper.

[0005] The technical solution of this utility model is as follows: An intelligent assembly station device with a quick-change gripper, comprising a mounting base, a movable block, a lead screw, and gears. The mounting base has two mounting slots, and gears are installed in the mounting slots. The gears mesh with corresponding upper and lower racks, respectively. The gears are fixedly connected to the outer wall of the lead screw. One end of the lead screw is connected to one side of the mounting slot via a bearing, and the other end of the lead screw has a knob. Four movable blocks are evenly arranged on the outer side of the mounting base, and the lead screw passes through the corresponding movable blocks. A torsion spring is fixedly connected to one side of the outer wall of the movable block, and one end of the torsion spring is connected to a connecting rod. A buckle is fixedly connected to the outer wall of the connecting rod. The lead screw can be rotated by the knob, and the rotation of the lead screw drives the movable blocks on both sides to move. The torsion spring provides clamping force for the buckle to fix the mounting plate.

[0006] When using the intelligent assembly station device with a quick-change gripper in this solution, adjusting the moving block requires turning the knob at one end of the lead screw. The lead screw drives the gear to rotate synchronously, and the gear meshes with the upper and lower racks, driving the moving blocks on both sides to move precisely along a preset trajectory, avoiding adjustment deviations and allowing the clips to accurately clamp the mounting plate. When installing the gripper, the threaded rod of the mounting plate is passed through the through hole of the mounting base, and the nut is tightened to fix it. The threaded rod length is adapted to fully lock it in place, preventing the mounting plate from shaking. At the same time, the lead screw-gear drive clip provides clamping force, forming a double guarantee with the rigid fixation of the threaded rod to prevent loosening. When replacing the gripper, simply loosen the nut, adjust the knob to release the clip, and the mounting plate can be removed for replacement without disassembling the main body of the device, making the operation highly efficient.

[0007] Preferably, the upper rack and the lower rack are respectively fixedly connected to the outer wall of one side of the moving block that is centered. Two limiting rods are fixedly connected to the outer wall of one side of the moving block. One end of the limiting rod is located in the mounting base. After the lead screw rotates, the moving blocks on both sides of the lead screw move in a centered manner.

[0008] Preferably, a mounting plate is provided below the mounting base, four threaded rods are provided on the upper outer wall of the mounting plate, and a mechanical gripper is fixedly connected to the lower outer wall of the mounting plate.

[0009] Preferably, the mounting base has four through holes, the threaded rod passes through the corresponding through holes, and a nut is provided at the upper end of the threaded rod for fixing the threaded rod.

[0010] Preferably, the length of the threaded rod is greater than the length of the through hole plus the thickness of the nut.

[0011] Preferably, the upper outer wall of the mounting base is fixedly connected with a hanging lug, which provides a fulcrum for connecting the mounting base to external fixed equipment.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This utility model achieves precise centering movement of the moving blocks through the transmission and engagement of a lead screw and gear. One end of the lead screw is connected to a knob; rotating the knob drives the gear to rotate synchronously. The gear meshes with the upper and lower racks, stably driving the moving blocks on both sides to move towards or away from each other along a preset trajectory. This avoids deviations during adjustment, significantly improves the accuracy of the moving block's movement, and allows the latch to accurately clamp the mounting plate.

[0014] Second, based on the first beneficial effect, the dual fixing structure of the threaded rod and nut further enhances the stability and practicality of the device. After the threaded rod passes through the through hole of the mounting base, the mounting plate is fixed to the mounting base by tightening the nut. The length of the threaded rod is reasonably designed to ensure that the nut can be fully locked, preventing the mounting plate from shaking during operation. At the same time, based on the clamping force provided by the screw-gear driven buckle, the rigid fixing of the threaded rod and the elastic clamping of the buckle form a double guarantee. This not only solves the loosening risk that may exist in a single fixing method, but also allows the mounting plate to be quickly removed when changing the gripper by simply loosening the nut and cooperating with the buckle to release the action, without disassembling the main components of the device, making the gripper replacement process more efficient.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this embodiment is an intelligent assembly station device with a quick-change gripper, including a mounting base 17, a movable block 3, a lead screw 10, and a gear 16. The mounting base 17 has two mounting slots 8, and the gear 16 is installed in each mounting slot 8. The gear 16 meshes with the corresponding upper rack 14 and lower rack 15, respectively. The gear 16 is fixedly connected to the outer wall of the lead screw 10. One end of the lead screw 10 is connected to one side of the mounting slot 8 via a bearing, and the other end of the lead screw 10 has a knob 13. Four movable blocks 3 are evenly arranged on the outer side of the mounting base 17, and the lead screw 10 passes through the corresponding movable block 3. The outer wall of one side of the movable block 3... A torsion spring 5 is fixedly connected, with one end of the torsion spring 5 connected to the connecting rod 18. A buckle 4 is fixedly connected to the outer wall of the connecting rod 18. In use, the screw 10 is rotated by rotating the knob 13, and the screw 10 drives the gear 16 to rotate synchronously. The gear 16 drives the upper rack 14 and the lower rack 15 to move in opposite linear directions, thereby driving the corresponding moving block 3 to move synchronously, so that the buckle 4 moves closer to or away from the mounting plate 11. At the same time, the torsion spring 5 generates torque through its own elastic deformation, providing a continuous clamping force for the buckle 4, ensuring that the buckle 4 is stably engaged with or smoothly disengaged from the mounting plate 11.

[0028] Example 2

[0029] Please see Figures 1-4 As shown, this embodiment, based on embodiment 1, further includes: the upper rack 14 and the lower rack 15 are respectively fixedly connected to the outer wall of one side of the moving block 3 that is moving in a centered manner. Two limiting rods 7 are fixedly connected to the outer wall of one side of the moving block 3. One end of the limiting rod 7 is located inside the mounting base 17. In use, the lead screw 10 rotates to drive the gear 16 to mesh with the upper rack 14 and the lower rack 15, so that the moving blocks 3 on both sides move in opposite or opposite directions to make centered movements. The limiting rods 7 move synchronously with the moving blocks 3 and slide within the mounting base 17. The movement trajectory of the moving block 3 is restricted by the cooperation between the limiting rods 7 and the mounting base 17, preventing the moving block 3 from deviating or rotating during movement, and ensuring the stability and accuracy of the movement of the moving block 3.

[0030] A mounting plate 11 is provided below the mounting base 17. Four threaded rods 6 are provided on the upper outer wall of the mounting plate 11. Mechanical grippers 12 are fixedly connected to the lower outer wall of the mounting plate 11. In use, the mounting plate 11 is connected to the mounting base 17 through the threaded rods 6. The mechanical grippers 12 move synchronously with the mounting plate 11. When it is necessary to replace the mechanical grippers 12 of different specifications, it is only necessary to disassemble the mounting plate 11 to achieve quick replacement of the mechanical grippers 12 without adjusting the main structure of the device, thus improving the efficiency of replacement.

[0031] The mounting base 17 has four through holes 2. The threaded rod 6 passes through the corresponding through holes 2. The upper end of the threaded rod 6 is provided with a nut 9. In use, after the threaded rod 6 passes through the through hole 2, the mounting plate 11 is fixedly connected to the mounting base 17 by tightening the nut 9 to prevent the mounting plate 11 from shaking or falling off during operation. When disassembling, simply loosen the nut 9 to remove the mounting plate 11 from the mounting base 17. The operation is simple and quick.

[0032] The length of the threaded rod 6 is greater than the length of the through hole 2 plus the thickness of the nut 9. When in use, after the threaded rod 6 passes through the through hole 2, its upper end can be reserved with sufficient length for the nut 9 to tighten and fix it, avoiding the problem that the nut 9 cannot be effectively fixed due to insufficient length of the threaded rod 6. At the same time, it provides operating space for the installation and disassembly of the mounting plate 11, ensuring the reliability of the connection structure.

[0033] The upper outer wall of the mounting base 17 is fixedly connected with a hanging ear 1. In use, the hanging ear 1 can be connected to external mechanical arms, guide rails and other fixed equipment through bolts, hooks and other connectors to provide a stable mounting support for the entire device, so that the device can move or be positioned synchronously with external equipment to meet the position adjustment needs in different assembly scenarios.

[0034] Instructions for use: When using this device, to adjust the moving block 3, rotate the knob 13 at one end of the lead screw 10. The lead screw 10 drives the gear 16 to rotate synchronously. The gear 16 meshes with the upper and lower racks 15, driving the moving blocks 3 on both sides to move precisely along the preset trajectory, avoiding adjustment deviations and allowing the buckle 4 to accurately clamp the mounting plate 11. When installing the gripper, insert the threaded rod 6 of the mounting plate 11 through the through hole 2 of the mounting base 17 and tighten the nut 9 to fix it. The threaded rod 6 is of suitable length and can be fully locked to prevent the mounting plate 11 from shaking. At the same time, the lead screw 10 and gear 16 drive the buckle 4 to provide clamping force, forming a double guarantee with the rigid fixation of the threaded rod 6 to prevent loosening. When replacing the gripper, simply loosen the nut 9 and adjust the knob 13 to release the buckle 4, then remove the mounting plate 11 for replacement. There is no need to disassemble the main body of the device, making the operation highly efficient. Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
