Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, specifically a fabric gripping device. Background Technology

[0002] In garment manufacturing, before processes such as patch sewing and binding, fabric (especially small pieces) needs to be precisely placed in designated positions to await subsequent processing. Currently, this fabric placement process relies entirely on manual operation: operators must repeatedly pick up and place the fabric, layering multiple layers one by one. This manual method has several drawbacks: first, the operation is tedious and repetitive, easily leading to worker fatigue, thus reducing production efficiency and increasing labor costs; second, the positional deviation of manually placed fabric is uncontrollable, making it impossible to guarantee consistent placement accuracy for each piece, directly affecting the stability of subsequent sewing processes and resulting in inconsistent product quality; third, when manually picking up layers of fabric, multiple pieces are prone to sticking together or being missed, further restricting the continuity and reliability of the production process. Therefore, a fabric picking device needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a fabric gripping device that solves the problem of insufficient effectiveness of manual fabric gripping.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fabric gripping device, comprising a cylinder fixing plate, a lifting cylinder fixedly mounted at the front end of the cylinder fixing plate, a push plate fixedly mounted at the lower end of the output end of the lifting cylinder, a cylinder connecting plate fixedly mounted at the front end of the push plate, four evenly distributed waist grooves on the top of the front end of the cylinder connecting plate, two symmetrically distributed L-shaped components fixedly mounted at the bottom of the cylinder connecting plate, a linear guide rail at the front end of the L-shaped components, a mounting plate at the front end of the linear guide rail, a mounting hole at the top of the mounting plate, a needle gripper fixedly mounted at the front end of the mounting plate through the mounting hole, and a spring buffer mechanism shared between the mounting plate and the L-shaped components.

[0005] Preferably, a fabric detection optical fiber is fixedly installed at the front end of the cylinder connecting plate. By designing the fabric detection optical fiber, the fabric position can be detected.

[0006] Preferably, the top of the L-shaped component has four evenly distributed fixing holes, which communicate with the waist groove. By designing the fit between the fixing holes and the waist groove, the installation position of the L-shaped component can be adjusted.

[0007] Preferably, the mounting plate has a first connection hole on its side, and the L-shaped component has a second connection hole on its side. The spring buffer mechanism is fixedly installed through the first and second connection holes. The design of the first and second connection holes facilitates the installation and use of the spring buffer mechanism.

[0008] Preferably, the needle gripper has a built-in pneumatic component, and the bottom of the needle gripper has multiple sets of regularly arranged sharp needles, which are crisscrossed and angled. This needle gripper design facilitates the gripping of fabric.

[0009] Preferably, a limiting post is provided on one side of the mounting plate, and the height of the limiting post is adapted to the stroke of the linear guide rail. By setting the limiting post, the sliding limit position of the mounting plate along the linear guide rail can be restricted.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model automates the layering and placement of fabrics, completely replacing traditional manual operations. It avoids the inefficiency caused by repetitive labor, significantly improves batch production efficiency, reduces reliance on manpower, and effectively lowers enterprise labor costs. Simultaneously, the automated gripping process precisely controls the layering and placement of the fabrics, solving the problem of uncontrollable positional deviations in manual operations and significantly improving the consistency and stability of product quality.

[0011] 2. This utility model adopts a needle-type gripper design. Pneumatic components drive regularly arranged sharp needles to insert obliquely into the fabric without penetrating it. The needle tip extension length and force can be adjusted according to process requirements to ensure the effectiveness of layered gripping.

During operation, the multi-layered fabric to be gripped is first placed in the designated position. The linear guide rail 8 drives the entire gripping mechanism to move to the fabric gripping position. The lifting cylinder 2 drives the push plate 3 to move down, and the push plate 3 drives the cylinder connecting plate 4 to move down. The cylinder connecting plate 4 drives the needle gripper 10 to move down, causing the mechanism to descend. During the downward pressure, the spring buffer mechanism 12 plays a buffering role to avoid excessive pressure damaging the fabric. When the mechanism reaches the preset position, the pneumatic component drives the needle of the needle gripper 10 to extend regularly and insert obliquely into the top layer of fabric. The fabric detection fiber optic 5 detects in real time whether the fabric has been successfully gripped. After confirming the gripping, the lifting cylinder 2 drives the mechanism to rise to the designated height. Then, the linear guide rail 8 drives the gripping mechanism to move to the material release position, and the pneumatic component controls the needle to return to its original position, releasing the fabric to the designated area, completing one fabric gripping and placement cycle, realizing automatic layered gripping and precise placement of multi-layered fabrics.
