Description

Technical Field

[0001] The utility model relates to the technical field of cover-opening machines, in particular to a cover-opening head with a rotating hook. Background Art

[0002] During the production process of PCB boards, protective covers are usually placed for capping to protect electrical components. Mylar is used on some end surfaces of electrical components to prevent the connecting pins of the electrical components from being impacted, squeezed, scratched, etc., to avoid damage to them during transportation or delivery. The cover and Mylar can effectively prevent damage to the electrical components on the upper end of the PCB board.

[0003] During the assembly process, the protective cover and Mylar tape on the surface need to be removed. In traditional operations, since the Mylar tape is a flexible material, general robots cannot remove it in one go, the grippers are not sensitive enough, and manual assistance is required to remove it, resulting in low production efficiency.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] Example

[0019] like Figure 1-2 As shown, a cover-lifting head with a rotating hook comprises a driving cylinder 1, a guide rod 2, a positioning seat 3 and a floating seat 4. A rotating seat 5 connected to the guide rod 2 is provided between the driving cylinder 1 and the positioning seat 3. A hook 6 is connected to the lower end of the guide rod 2. A guide sleeve 7 is provided in the rotating seat 5. A pressure rod 8 is provided in the guide sleeve 7. A proximity switch 14 is also provided at the rear end of the guide sleeve 7. The rotating seat 5 is connected to the positioning seat 3 by two spring rods 9.

[0020] A cover plate 10 is provided at the upper end of the rotating seat 5. A guide hole 11 matching one end of the telescopic rod of the driving cylinder 1 is opened on the cover plate 10 and the rotating seat 5. One end of the telescopic rod of the driving cylinder 1 is inserted into the guide hole 11 to press the pressure rod 8 downward, and the guide rod 2 is positioned and guided by the rotating seat 5.

[0021] The inner side of the guide sleeve 7 is provided with a mounting groove matching the pressure rod 8. The inner diameter of the guide sleeve 7 is consistent with the outer diameter of the telescopic rod of the driving cylinder 1. A telescopic spring 12 is sleeved on the upper end of the guide rod 2. Top plates 13 are provided on both sides of the guide rod 2 close to the telescopic spring 12. After the driving cylinder 1 is started, one end of the telescopic rod is pushed downward, and the upper end surface of the top plate 13 is an inclined surface. A plurality of pressing teeth 81 are provided at the lower end of the pressure rod 8, and the plurality of pressing teeth 81 are in contact with the top plate 13. The telescopic rod of the driving cylinder 1 presses the pressure rod 8 downward, and the top plate 13 slides along the pressing teeth 81 after being squeezed, so as to realize the rotation of the guide rod 2. After the rotation, the top plate 13 on the guide rod 2 is stuck in the plurality of pressing teeth 81. The pressure rod 8 is sleeved on the guide rod 2 and is located at the upper end of the telescopic spring 12. The guide rod 2 is automatically retracted by the telescopic spring 12.

[0022] The hook needle 6 and the guide rod 2 are integrally formed. When the guide rod 2 descends, the hook needle 6 is driven to extend out of the floating seat 4 and rotate. When the guide rod 2 retracts, the hook needle 6 moves upward while rotating to hook up the Mylar tape that is difficult to peel off.

[0023] When in use, the driving cylinder 1 pushes the pressure rod 8 downward, and the pressure tooth 81 at the lower end of the pressure rod 8 squeezes the top plate 13 on the guide rod 2, so that the guide rod 2 rotates, driving the hook needle 6 to descend, extend and rotate, and hook the Mylar tape through the rotation action. When retracting, the Mylar tape is also torn and peeled off by rotation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
