Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a hair clip clamping mechanism, including a base 1. A support seat 2 is fixedly connected to the top of the base 1. A rotating shaft 3 is rotatably connected to the top front side of the support seat 2. A connecting block 4 is installed on the rear side of the rotating shaft 3. A transmission block 5 is fixedly connected to the bottom of the connecting block 4. A sliding groove 6 is provided on the front side of the transmission block 5. A sliding rod 7 is slidably connected to the inner wall of the sliding groove 6. A pneumatic push rod 8 is rotatably connected to the rear end of the outer wall of the sliding rod 7. The pneumatic push rod 8 is installed on the rear side of the support seat 2. A slot 9 is provided on the front side of the rotating shaft 3. Positioning grooves 10 are provided on the rear ends of both the left and right sides of the inner wall of the slot 9. An installation block 11 is provided inside the slot 9. A screw hole 15 is provided on the front side of the installation block 11. 5. The screw 14 is internally threaded. The screw 14 is fixedly connected to the front side of the screw 14. The screw 13 is connected to the horizontal frame 20 through the bearing seat 12. The front end of the inner wall of the horizontal frame 20 is fixedly connected to the fixing plate 21. The fixing plate 21 is connected to the slide seat 23 through the sliding component 22. The slide seat 23 is connected to the extension rod 25 through the linear motor 24. The bottom of the extension rod 25 is equipped with a gripper 26. The rear ends of the left and right sides of the outer wall of the mounting block 11 are provided with sliding grooves 16. The sliding block 17 is slidably connected inside the sliding groove 16. The side of the sliding block 17 that is far apart is fixedly connected to the positioning block 18. The side of the sliding block 17 that is close to the sliding block 17 is fixedly connected to the spring 19. The base 1 is connected to the mounting platform 28 through the fixing bolt 27.
[0027] Specifically, when the pneumatic push rod 8 is working, it pushes the slide rod 7 to slide within the slide groove 6. Since the slide groove 6 is arc-shaped and the pneumatic push rod 8 is installed on the left side of the transmission block 5 on the support base 2, it drives the transmission block 5 to rotate stably around the rotating shaft 3. When the gripper 26 clamps the hair clip, the rotation of the transmission block 5, combined with the sliding of the slide rod 7 within the arc-shaped slide groove 6, allows the hair clip clamping component to simultaneously complete the rotation and extension actions, accurately placing the hair clip into the collection frame. This greatly improves the flexibility and efficiency of clamping, optimizes the hair clip collection process, and compared to the ordinary straight slide groove design, the arc-shaped slide groove 6 greatly expands the working range and angle of clamping and placing, reduces adjustment time, significantly improves work efficiency and operational flexibility, and meets the actual needs of quickly clamping and placing hair clips.
[0028] The mounting block 11 is set in the slot 9, and in the sliding groove 16 on the left and right rear ends of its outer wall. Under the action of the spring 19, the slider 17 can drive the positioning block 18 to cooperate with the positioning groove 10, so as to achieve stable positioning of the mounting block 11 in the slot 9, ensuring the stability of subsequent component installation. Under the elastic action of the spring 19, the positioning block 18 can quickly and tightly embed into the positioning groove 10, so as to achieve rapid and stable positioning of the mounting block 11 in the slot 9. This design greatly facilitates the quick loading and unloading of the mounting block 11. When it is necessary to maintain, adjust or replace some components of the clamping mechanism, the staff can easily complete the operation, greatly shortening the downtime. It provides hardware maintainability guarantee for quick clamping and placing of hair clips, so that the equipment can be put into use in good working condition at any time. By rotating the rotating block 13, the screw 14 is driven to rotate in the screw hole 15, and the front and rear position of the mounting block 11 in the slot 9 can be adjusted, so as to quickly and accurately adjust the position for installation according to the installation position requirements.
[0029] Reference Figures 1-3 The slide groove 6 is arc-shaped. The pneumatic push rod 8 is installed on the left side of the transmission block 5 of the support seat 2. The horizontal frame 20 is fixedly connected to the outside of the shaft seat 12. The rotating block 13 is rotatably connected to the front side of the shaft seat 12. The positioning block 18 is adapted to the size of the positioning groove 10. The sliding assembly 22 includes a pneumatic push rod 2201. The pneumatic push rod 2201 and the limiting rod 2202 pass through and are fixedly connected to the rear end of the horizontal frame 20. The front end of the pneumatic push rod 2201 passes through the rear side of the fixing plate 21. The limiting rod 2202 is fixedly connected to the left and right ends of the inner wall of the horizontal frame 20. The limiting rod 2202 passes through the slide seat 23 and is slidably connected to it. The left and right ends of the rear side of the fixing plate 21 are fixedly connected to dampers 29. The linear motor 24 is fixedly connected to the top of the slide seat 23.
[0030] Specifically, when the pneumatic push rod 2201 is working, it can precisely push the slide 23 to slide along the limit rod 2202. The limit rod 2202 ensures the stability and accuracy of the slide 23 and avoids deviation. The damping 29 fixedly connected to the left and right ends of the rear side of the fixed plate 21 can buffer and stabilize the slide 23, preventing it from sliding too fast or shaking, and further improving the smoothness of the slide 23's movement. The linear motor 24 is fixed to the top of the slide 23 and can drive the extension rod 25 to drive the gripper 26 to move linearly, realizing precise control of the position of the gripper 26, thereby accurately gripping the hair clip and greatly improving the success rate and work quality of gripping.
[0031] Working principle: During operation, the base 1 is securely connected to the mounting platform 28 via the fixing bolt 27, and the support seat 2 is fixed to the top of the base 1 to provide support; the pneumatic push rod 8 works, pushing the slide rod 7 to slide in the arc-shaped slide groove 6 on the front side of the transmission block 5, causing the transmission block 5 to rotate stably around the rotating shaft 3. In conjunction with the gripper 26, after clamping the hair clip, it can simultaneously complete the rotation and extension actions, accurately placing the hair clip into the collection frame, expanding the working range and angle, and improving efficiency and flexibility; the mounting block 11 is placed in the slot 9, and the slider 17, under the action of the spring 19, drives the positioning block 18 and... The positioning groove 10 cooperates to achieve quick and stable positioning and facilitates loading, unloading and maintenance. Rotating the rotating block 13 can drive the screw 14 to rotate in the screw hole 15, and adjust the front and rear position of the mounting block 11 in the slot 9 for precise installation and positioning. The pneumatic push rod 2201 works to push the slide 23 to slide along the limit rod 2202. The limit rod 2202 ensures stable and accurate sliding. The damping 29 on the rear side of the fixing plate 21 buffers and stabilizes the slide 23. The linear motor 24 drives the extension rod 25 to drive the gripper 26 to move linearly, and precisely control the position of the gripper 26 to improve the success rate of gripping and work quality.
