Description

Technical Field

[0001] This utility model belongs to the field of button fastener technology, and in particular relates to a button clip bracket. Background Technology

[0002] Currently, in the production of textile products such as clothing and bags, stable clamping and precise operation of buttons are crucial to production efficiency and quality. With the development of automation in manufacturing, traditional manual button clamping is difficult to meet the needs of mass production due to high labor intensity, high cost, large errors, and efficiency limitations imposed by human factors. Although some production lines use automated button clamping equipment, these devices suffer from insufficient clamping stability: lack of precise force transmission and stroke control, poor adaptability; low functional integration: clamping and thread loosening functions are designed separately, increasing equipment complexity and cost; and poor structural adaptability: the bracket and drive components are fixed, resulting in cumbersome adjustments. Meanwhile, the textile industry is developing towards multi-variety, small-batch, and high-precision production, placing new demands on button clamping equipment for stable clamping, functional linkage integration, and flexible adjustment.

[0003] Therefore, we need to design a clip bracket to solve these problems. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a button clip bracket.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A clip bracket includes a main bracket, on which a connecting bracket and a clip body are fixedly mounted. The clip body is provided with a clamping arm and a clip push-pull bracket. There are two clamping arms, one end of which is hinged to the clip body. A push-pull column is fixedly mounted in the middle of the clamping arm. The clip push-pull bracket is slidably connected to the clip body. A push-pull groove is formed on the clip push-pull bracket, and the push-pull column is located in the push-pull groove.

[0007] A cylinder bracket is provided on the connecting frame, and a gripping cylinder is hinged on the cylinder bracket. The output end of the gripping cylinder is hinged to the claw push-pull frame. When the claw push-pull frame slides relative to the claw body, the free ends of the clamping arms will move closer or further apart.

[0008] A base plate is fixedly mounted on the button claw push-pull frame, and a thread loosening needle is fixedly mounted on the base plate. When the clamping arm holds the button, the thread loosening needle slides from above the button. The thread loosening needle is linked to the clamping arm's clamping action; by sliding from above the button while the clamping arm holds it, the button's stitching can be straightened or loosened simultaneously. By integrating the clamping and thread loosening functions, the automation process is simplified, reducing the overall complexity and cost of the equipment. Simultaneously, it eliminates the need for manual thread loosening, improving the efficiency and automation of button processing.

[0009] Preferably, the connecting bracket is L-shaped, with one end fixedly connected to the main bracket, and the cylinder bracket connected to the other end of the connecting bracket. Two limiting strips are fixedly provided on one side of the cylinder, and the cylinder bracket is located between the two limiting strips. An elongated hole is provided on the cylinder bracket at one end of the two limiting strips, and the cylinder bracket is fixedly connected to the connecting bracket through the elongated hole. A connecting seat is fixedly provided on the cylinder bracket at the other end of the two limiting strips, and the gripping cylinder is hinged to the cylinder bracket through the connecting seat.

[0010] This design, with its L-shaped connecting bracket, allows the cylinder's installation position to match the direction of force transmission, reducing power loss. The limiting strip provides lateral positioning for the cylinder bracket, preventing displacement under load and ensuring the stability of the cylinder drive. The elongated hole design provides adjustment space for the cylinder bracket's installation position, facilitating adjustments to the relative positions of the cylinder and the latch push-pull bracket according to actual usage scenarios, improving the overall assembly flexibility and compatibility.

[0011] Preferably, the opposing surfaces of the two limiting strips are parallel to each other, and the distance between the two limiting strips is the same as the width of the connecting frame.

[0012] This configuration, with the two limiting strips parallel to each other and spaced to match the width of the connecting bracket, enables precise positioning of the connecting bracket, preventing lateral swaying during installation and use. This close-fitting assembly enhances the stability of the connection between the connecting bracket and the cylinder bracket, reduces vibration caused by gaps between components, and thus improves the structural stability and service life of the entire clamping bracket during high-frequency clamping operations.

[0013] Preferably, a fisheye connector is fixedly provided at the output end of the gripper cylinder, and a connecting block is fixedly provided on the claw push-pull frame, with the fisheye connector rotatably connected to the connecting block.

[0014] This design allows the fisheye connector to have an angle compensation function, adapting to the relative rotation between the output end of the gripper cylinder and the connecting block, thus preventing jamming during movement. This rotary connection method reduces rigid friction between components, lowers the wear rate, and makes power transmission smoother, ensuring smooth and continuous sliding motion of the claw push-pull frame and improving the reliability of the clamping action.

[0015] The advantages and positive effects of this utility model are:

[0016] This invention utilizes a cylinder to drive the sliding of the gripper push-pull frame, and the opening and closing of the clamping arms is achieved through the cooperation of the push-pull groove and push-pull column, making the transmission path clear and direct. The gripping cylinder provides a stable driving force, ensuring uniform clamping force and preventing damage caused by uneven force during button clamping. The connecting bracket and cylinder bracket are connected via elongated holes, allowing adjustment of the gripping cylinder's installation position. Simultaneously, the symmetrical hinged design of the two clamping arms ensures synchronized opening and closing actions, improving adaptability to buttons of different sizes and clamping accuracy, meeting the stable gripping requirements of automated operations.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] Example 1: As Figures 1-7As shown, a clip bracket includes a main bracket 1, on which a connecting bracket 2 and a clip body 4 are fixedly mounted. The main bracket 1 serves as the mounting base for the overall structure, providing fixed support for the connecting bracket 2 and the clip body 4, maintaining their preset relative positions, and ensuring accurate transmission of subsequent movements. The clip body 4 is provided with two clamping arms 7 and a clip push-pull bracket 6. Each clamping arm 7 has one end hinged to the clip body 4, allowing the clamping arms 7 to rotate around the hinge point, providing a basis for opening and closing. A push-pull column 16 is fixedly mounted in the middle of the clamping arm 7, moving synchronously with the clamping arm 7. The clip push-pull bracket 6 is slidably connected to the clip body 4, and the clip body 4 provides sliding guidance for the clip push-pull bracket 6. A push-pull groove 15 is formed on the clip push-pull bracket 6. 16 is located within the push-pull groove 15. The push-pull groove 15, through its cooperation with the push-pull column 16, converts the linear motion of the buckle push-pull frame 6 into the rotation of the clamping arm 7. A cylinder bracket 3 is provided on the connecting frame, which provides a mounting carrier for the cylinder bracket 3. A gripping cylinder 5 is hinged on the cylinder bracket 3, which provides fixed and hinged support for the gripping cylinder 5, allowing the gripping cylinder 5 to be finely adjusted around the hinge point. The output end of the gripping cylinder 5 is hinged to the buckle push-pull frame 6, and the output force of the gripping cylinder 5 can be directly transmitted to the buckle push-pull frame 6. When the buckle push-pull frame 6 slides relative to the buckle body 4 under the drive of the gripping cylinder 5, the push-pull groove 15 pushes or pulls the push-pull column 16, causing the clamping arm 7 to rotate around the hinge point, ultimately causing the free ends of the clamping arms 7 to move closer or further apart, thus achieving the clamping and release of the button 19.

[0031] The connecting bracket 2 is L-shaped, with one end fixedly connected to the main bracket 1. The L-shaped structure can change the direction of force transmission and optimize the spatial layout of the main bracket 1 and the cylinder bracket 3. The cylinder bracket 3 is connected to the other end of the connecting bracket 2, and the connecting bracket 2 transmits the supporting force of the main bracket 1 to the cylinder bracket 3. Two limiting strips 18 are fixedly installed on one side of the cylinder, and the limiting strips 18 are fixed synchronously with the cylinder. The cylinder bracket 3 is located between the two limiting strips 18, and the two limiting strips 18 form a lateral constraint on the cylinder bracket 3 to prevent the cylinder bracket 3 from shifting laterally. A long... The elongated hole 24 provides adjustment margin for the installation position of the cylinder bracket 3. The cylinder bracket 3 is fixedly connected to the connecting bracket 2 through the elongated hole 24. By adjusting the fixed position of the cylinder bracket 3 in the elongated hole 24, the relative distance between the cylinder bracket 3 and the connecting bracket 2 can be changed. A connecting seat 17 is fixedly provided on the cylinder bracket 3 at the other end of the two limiting strips 18. The connecting seat 17 provides a hinge point for the gripping cylinder 5. The gripping cylinder 5 is hinged to the cylinder bracket 3 through the connecting seat 17. The connecting seat 17 makes the hinge position of the gripping cylinder 5 cooperate with the limiting strips 18, further ensuring the installation stability of the gripping cylinder 5.

[0032] The opposing surfaces of the two limiting strips 18 are parallel to each other, and the distance between the two limiting strips 18 is the same as the width of the connecting frame. This size matching allows the connecting frame to be precisely embedded between the two limiting strips 18. The limiting strips 18 form a tight lateral limit on the connecting frame, preventing the connecting frame from lateral shaking during installation or under stress. At the same time, the parallel opposing surfaces ensure uniform contact between the connecting frame and the limiting strips 18, reducing local stress concentration and making the connection between the connecting frame and the cylinder bracket 3 more stable, ensuring the stability of the force transmission from the connecting frame to the cylinder bracket 3.

[0033] A base plate 8 is also fixedly installed on the claw push-pull frame 6. The base plate 8 moves synchronously with the claw push-pull frame 6. A loosening needle 9 is fixedly installed on the base plate 8. The base plate 8 provides fixed support for the loosening needle 9, so that the loosening needle 9 and the claw push-pull frame 6 remain relatively stationary. When the clamping arm 7 clamps the button 19 under the drive of the claw push-pull frame 6, the movement of the claw push-pull frame 6 synchronously drives the base plate 8 and the loosening needle 9 to move, so that the loosening needle 9 slides from above the button 19, realizing the linkage between the loosening action and the clamping action, and the loosening operation can be completed without additional driving components.

[0034] The main body 4 of the latch has a limiting groove 22, which provides a sliding track for the limiting block 23. The limiting block 23 is fixedly installed on the latch push-pull frame 6. The limiting block 23 moves synchronously with the latch push-pull frame 6. The thickness of the limiting block 23 is equal to the sum of the depth of the limiting groove 22 and the thickness of the clamping arm 7. This thickness matching ensures that the limiting block 23 will not cause spatial interference with the clamping arm 7 after it is embedded in the limiting groove 22. The limiting block 23 is located in the limiting groove 22 and slides with the limiting groove 22. The limiting groove 22, through its cooperation with the limiting block 23, forms a precise constraint on the sliding direction of the latch push-pull frame 6, preventing the latch push-pull frame 6 from deviating or jamming during sliding, and ensuring the linearity of the movement of the latch push-pull frame 6.

[0035] The main body 4 of the latch is also provided with a sliding groove 21 and a limiting rotating rod 10. The sliding groove 21 is opened through the middle of the main body 4 of the latch and provides a moving channel for the limiting bolt 13. A fixing bolt 14 is provided on one side of the main body 4 of the latch with the sliding groove 21. The fixing bolt 14 provides a hinge point for the limiting rotating rod 10, and an adjusting knob 12 is provided on the other side. The adjusting knob 12 is threadedly engaged with the main body 4 of the latch. The limiting rotating rod 10 is located above the sliding groove 21, and one end is hinged to the main body 4 of the latch by the fixing bolt 14. The limiting rotating rod 10 can rotate around the fixing bolt 14. The other end of the limiting rotating rod 10 is provided with a rotating groove 11. 11 provides space for adjusting the knob 12. The knob 12 interacts with the limiting rotating rod 10 through the rotating groove 11. Rotating the knob 12 can push the limiting rotating rod 10 to rotate around the fixing bolt 14, changing the tilt angle of the limiting rotating rod 10. A limiting bolt 13 is also provided on the claw push-pull frame 6. The limiting bolt 13 moves synchronously with the claw push-pull frame 6. The free end of the limiting bolt 13 passes through the sliding groove 21 and is located on one side of the limiting rotating rod 10. When the claw push-pull frame 6 slides, the limiting bolt 13 moves along the sliding groove 21. The limiting rotating rod 10 limits the sliding stroke of the claw push-pull frame 6 by blocking the limiting bolt 13, thereby controlling the opening and closing range of the clamping arm 7.

[0036] One end of the clamping arm 7 is hinged to the main body 4 of the buckle via a rotating shaft 20. The rotating shaft 20 provides a stable rotation fulcrum for the clamping arm 7, ensuring the coaxiality of the clamping arm 7 during rotation. The two clamping arms 7 are symmetrically distributed along the limiting groove 22. The limiting groove 22 provides a positioning reference for the symmetrical distribution of the clamping arms 7, making the movement trajectories of the two clamping arms 7 symmetrical. This ensures that the clamping force of the clamping arms 7 on the button 19 is evenly distributed in the center of the button 19, preventing the button 19 from falling off due to force deviation.

[0037] The working process of this embodiment is as follows: Before use, the installation position of the cylinder bracket 3 is first adjusted through the elongated hole 24 so that the installation position of the cylinder bracket 3 and the gripping cylinder 5 can match the buckle push-pull frame 6 and the clamping arm 7. Then, according to the size of the button 19, the position of the limiting rotating rod 10 is adjusted by rotating the adjusting knob 12. The clamping arm 7 is adjusted by the cooperation of the limiting rotating rod 10 and the limiting bolt 13 so that the gripping limit of the clamping arm 7 matches the size of the button 19. Then, the height of the loosening needle 9 is adjusted according to the thickness of the button 19 so that the loosening needle 9 can slide against the top surface of the clamped button 19.

[0038] During operation, the gripping cylinder 5 first shortens, causing the button claw push-pull frame 6 to slide inward. With the cooperation of the push-pull groove 15 and the push-pull column 16, the two clamping arms 7 open. At the same time, the loosening needle 9 also moves inward with the button claw push-pull frame 6. When the button 19 enters between the two clamping arms 7, the gripping cylinder 5 extends, pushing the button claw push-pull frame 6 outward. With the cooperation of the push-pull groove 15 and the push-pull column 16, the clamping arms 7 close to clamp the button 19. At the same time, the loosening needle 9 slides over the top of the button 19 to comb or loosen the stitching on the surface of the button 19.

[0039] A fisheye connector 25 is fixedly installed at the output end of the gripper cylinder 5, and a connecting block 26 is fixedly installed on the claw push-pull frame 6. The fisheye connector 25 and the connecting block 26 are rotatably connected. The fisheye connector 25 has an angle compensation function, which can adapt to the relative rotation between the output end of the gripper cylinder 5 and the connecting block 26, avoiding jamming during movement. This rotatable connection method reduces rigid friction between components, lowers the wear rate, and makes power transmission smoother, ensuring that the sliding action of the claw push-pull frame 6 is stable and continuous, and improving the reliability of the gripping action.

[0040] Two regulating valves 27 are also provided on the gripping cylinder 5. The regulating valves 27 are connected to an external high-pressure air source. The gas flow rate can be adjusted by the regulating valves 27, thereby adjusting the extension and retraction speed of the gripping cylinder 5.

[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
