Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically referring to a column-type finger tooling. Background Technology

[0002] Currently, the variety of mattresses in the home furnishing industry is increasingly diverse, with composite mattresses being the most popular due to their superior overall performance. The general manufacturing process for a mattress typically includes the following steps: raw material preparation and inspection, spring processing, quilting and fabric cutting, mattress mesh fabrication, base layering and filling, and edge trimming, followed by finished product inspection and packaging. During the base layering and filling, cotton felt or other padding layers are laid on the mattress mesh, followed by the quilted fabric. Then, according to design requirements, comfort layer materials are filled in, such as bouncy cotton, mini bubble springs, horsehair, etc.

[0003] On the production line, these large and soft cotton felts are typically stacked and stored next to the assembly line. Two operators are needed to move them and manually lay them onto the fabric mesh on the workstation. Due to the large size and soft texture of the fabric, positional deviations are prone to occur during manual laying, affecting the accuracy of subsequent fabric placement. These deviations not only cause fabric wrinkles and affect the product's appearance, but also reduce subsequent sewing efficiency and production cycle time, becoming a bottleneck restricting overall production capacity and quality stability. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a column-type finger tool that can automatically grasp and position cotton felt.

[0005] The objective of this utility model can be achieved through the following technical solution: A column-type finger fixture includes a frame, a lifting column rotatably connected to the frame, a telescopic column connected to the lifting column, and a finger fixture connected to the telescopic column. The finger fixture includes a fixed square frame, with several clamping components arranged in an array on the fixed square frame. Each clamping component includes a first fixed plate fixedly connected to the lower end of the fixed square frame. The upper end of a telescopic rod is slidably connected to the first fixed plate, and the lower end of the telescopic rod is fixedly connected to a second fixed plate. A spring is sleeved on the telescopic rod, and the spring is also fixed between the first and second fixed plates. A drive seat is fixedly connected to the lower end of the second fixed plate. The drive seat has a drive cavity, and a drive piston rod is disposed in the drive cavity. Two opposing drive arms are hinged to the lower end of the drive piston rod, and the drive arms are also hinged to the drive seat. A clamping plate is fixedly connected to each drive arm.

[0006] In the aforementioned column-type finger fixture, the drive arm includes a horizontal wall and a vertical arm. The horizontal wall is provided with a first hinge hole, and the vertical arm is provided with a second hinge hole. The second hinge hole is located at the end connected to the horizontal wall, and the lower end of the vertical arm is fixedly connected to the clamping plate.

[0007] In the above-mentioned column-type finger fixture, a positioning seat is fixedly connected to the upper end of the first fixing plate, and a positioning protrusion protrudes from the upper end of the telescopic rod. After the telescopic rod passes through the positioning seat, it is abutted against the top surface of the positioning seat by the positioning protrusion.

[0008] In the aforementioned column-type finger fixture, the second fixing plate is fixedly connected by a positioning pin and a telescopic rod.

[0009] In the aforementioned column-type finger fixture, a lifting rack and a lifting slide rail are fixedly connected to the lifting column, a lifting plate is provided on the lifting slide rail, a lifting drive motor is fixedly connected to the lifting plate, and a gear shaft that cooperates with the lifting rack is connected to the lifting drive motor.

[0010] In the aforementioned column-type finger fixture, the lifting plate is fixedly connected to the telescopic column, a telescopic slide rail is fixedly connected to the telescopic column, a telescopic drive motor is fixedly connected to the lifting plate, the telescopic drive motor is connected to a pulley one, a pulley two is provided on the telescopic column, a synchronous belt is connected to the pulley one and the pulley two, a telescopic slider is connected to the synchronous belt, a telescopic slide plate is fixed on the telescopic slider, and the telescopic slide plate is connected to a fixed square frame. Compared with existing technologies, the technical advantages of this utility model are as follows: 1. By using columns, lifting and telescopic mechanisms, combined with the clamping function of matrix-arranged finger fixtures, the automatic grasping, handling, and precise placement of large-area soft cotton felt is achieved. This completely replaces the heavy manual operation that previously required two workers, freeing people from repetitive labor. The automated process is stable and reliable, unaffected by human fatigue, and can work continuously, greatly improving production cycle and overall capacity. 2. Through mechanical positioning and program control, the fixtures can accurately place the cotton felt in the designated positions on the bed net. This effectively avoids problems such as positional deviations, misalignments, and wrinkles that are easily caused by manual placement due to the softness and large size of the fabric. It provides a flat and accurate base for subsequent fabric placement and sewing processes, significantly improving the appearance and quality consistency of the final product. 3. The clamping components are arranged in a square array, and their coverage area can be designed and adjusted according to different sizes of mattresses and cotton felt, making it highly adaptable. The independent spring-telescopic rod structure of each clamping component constitutes a flexible cushioning system. When all the clamping plates press down into contact with the felt or mattress surface, the springs allow each clamping plate to float independently up and down according to the slight undulations of the contact surface. This ensures that all clamping plates effectively contact and grip the felt, preventing it from slipping off due to partial instability. The flexible contact prevents rigid impacts from damaging the soft felt or the underlying mattress springs. During placement, the cushioning structure ensures that the felt is evenly pressed onto the mattress, resulting in a smoother laying. Attached Figure Description

The telescopic slide plate 26 is connected to the fixed frame 4. Here, the synchronous belt 24 is preferably used to drive the telescopic slide plate 26 to slide back and forth. The lower end of the telescopic slide plate 26 is connected to a finger fixture. The finger fixture is connected by sliding back and forth on the telescopic column 3 via the telescopic slide plate 26. The finger fixture is driven to rotate by a fixture drive motor. Through the column, lifting and telescopic mechanisms, combined with the clamping function of the matrix-arranged finger fixtures, the automatic grasping, handling and precise laying of large areas of soft cotton felt is realized. It completely replaces the heavy manual operation that originally required two workers to complete, freeing people from repetitive labor.

The tooling is equipped with multiple sensors that, through mechanical positioning and program control, precisely place the cotton felt into the designated positions on the bed net. This effectively avoids problems such as positional deviations, misalignments, and wrinkles that are easily caused by manual placement due to the softness and large size of the fabric. It provides a flat and accurate base for subsequent fabric placement and sewing processes, significantly improving the final product's appearance and quality consistency.

[0021] The finger fixture includes a fixed frame 4, with several clamping components arranged in an array on the frame 4. Each clamping component includes a first fixed plate 5 fixedly connected to the lower end of the fixed frame 4. The upper end of a telescopic rod 6 is slidably connected to the first fixed plate 5, and the lower end of the telescopic rod 6 is fixedly connected to a second fixed plate 7.

Two opposing drive arms 11 are hinged to the lower end of the drive piston rod 10 and are also hinged to the drive seat 9. Clamping plates 12 are fixedly connected to the drive arms 11. The drive seat 9 is connected to an external air source to pneumatically drive the drive piston rod 10. When the drive piston rod 10 moves downward, it drives the two drive arms 11 to open; when it moves upward, it drives the two drive arms 11 to clamp. The two drive arms 11 then drive the two clamping plates 12 to clamp the felt. The drive arm 11 includes a horizontal wall 1101 and a vertical arm 1102. A first hinge hole 1103 is provided on the horizontal wall 1101, and a second hinge hole 1104 is provided on the vertical arm 1102.

The clamping plate 12 is made of a flexible and damping material. A positioning seat 13 is fixedly connected to the upper end of the first fixing plate 5. A positioning protrusion 601 protrudes from the upper end of the telescopic rod 6. After passing through the positioning seat 13, the telescopic rod 6 rests against the top surface of the positioning seat 13 by the positioning protrusion 601. The second fixing plate 7 is fixedly connected to the telescopic rod 6 via a positioning pin 14. The clamping components are arranged in a square array, and their coverage area can be designed and adjusted according to different sizes of mattresses and felts, offering wide adaptability. The independent spring 8-telescopic rod 6 structure of each clamping component constitutes a flexible cushioning system. When all the clamping plates 12 press down into contact with the felt or mattress surface, the spring 8 allows each clamping plate 12 to float independently up and down according to the slight undulations of the contact surface. This ensures that all clamping plates 12 effectively contact and grip the felt, preventing it from slipping off due to partial insufficiency. The flexible contact prevents rigid impacts from damaging the soft felt or the underlying mattress spring 8. During placement, the cushioning structure ensures that the felt is evenly pressed onto the mattress, resulting in a smoother laying.
