Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mattress processing technology, and specifically refers to a transfer fixture for a mattress processing production line that prevents damage. Background Technology
[0002] The production process of a spring mattress assembly line includes spring system manufacturing, filling layer processing, and edge sealing. Transferring between these stages requires transport equipment. However, existing transport equipment typically uses pneumatic grippers. These grippers descend, clamp the mattress on both sides, and lift it to a certain height. Then, they are moved along a track to the edge sealing station and lowered onto the assembly table. The grippers are then released and rotated back into place. However, the unevenness of the mattress sides prevents the gripping surface of the pneumatic grippers from fully contacting the mattress sides. This results in a small contact area and dispersed force points. The grippers may only contact the raised areas, while the recessed areas remain unsupported. Consequently, the clamping force cannot be evenly distributed throughout the mattress, making it prone to shaking or even falling during transport due to inertia or vibration. Furthermore, when the gripper contacts the uneven side, the raised part will be subjected to excessive local pressure, which may squeeze or tear the side fabric or edge padding layer, forming indentations, holes or wrinkles, reducing the product qualification rate. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a damage-resistant transfer fixture for mattress processing production lines. The technical problem this invention aims to solve is how to achieve stable, damage-free, and efficient transfer of mattresses, ensuring product quality and production continuity.
[0004] The purpose of this utility model can be achieved through the following technical solution: A transfer fixture for a mattress processing assembly line to prevent damage includes two parallel transverse support rods. Two longitudinal support rods 1 and 2 are fixedly connected between the two transverse support rods. The two longitudinal support rods 1 are located at the two ends of the two transverse support rods, and the two longitudinal support rods 2 are located in the middle of the two transverse support rods. Rotary joints are fixedly connected to the two longitudinal support rods 2. At least two longitudinal auxiliary rods are also fixed between the two transverse support rods. The longitudinal auxiliary rods are located between the longitudinal support rods 1 and 2. Two transverse auxiliary rods are fixed between the longitudinal support rods 1 and 2. The upper end of the longitudinal auxiliary rods is also fixedly connected to the transverse auxiliary rods through a fixing member 1. Several magnetic suction members are fixedly connected to the lower ends of the transverse support rods, longitudinal support rods 1 and 2, transverse auxiliary rods, and longitudinal auxiliary rods. A fixing rod is fixedly connected to the upper end of the transverse auxiliary rods. A cylinder is fixedly connected to the fixing rod. A release rod is connected to the cylinder. The release rod and the longitudinal auxiliary rods are arranged parallel to each other.
[0005] This solution abandons side clamping and instead uses magnetic attachments to attract metal parts of the mattress, such as springs or internal support frames. The magnetic attachments are evenly distributed below the support frame, which consists of horizontal support rods, vertical support rod one, vertical support rod two, horizontal auxiliary rods, and vertical auxiliary rods, forming a large-area attraction plane. As long as the internal metal parts of the mattress are within the attraction area, the magnetic force can be evenly applied to multiple points. The large and uniform contact surface completely avoids the uneven sides of the mattress, eliminating the problems of unstable clamping and excessive local pressure caused by the side shape. The magnetic force is a long-range force and will not exert direct physical pressure on the sides, edge filling layers, or fabric of the mattress, avoiding the formation of indentations, tears, holes, or wrinkles. Multiple magnetic attachments distributed beneath the support frame work simultaneously to provide a dispersed and uniform attraction force, firmly holding the mattress to the bottom plane of the fixture. This large-area, uniform attraction force effectively resists inertial forces and vibrations generated during transport, significantly reducing the risk of the mattress shaking, shifting, or even falling. Even if the mattress's internal structure has some unevenness, as long as there are enough magnetic attachment points and they are reasonably distributed, a stable attraction force can be provided. When the fixture moves to the target position and the mattress needs to be released, a cylinder pushes the release lever downwards. The release lever acts on the upper surface of the mattress, providing a downward thrust to help overcome the magnetic attraction force, achieving a controllable and reliable separation between the mattress and the magnetic attachments.
[0006] Furthermore, the cylinder includes two parallel piston rods, with a connecting block fixedly connected to the lower end of each piston rod. The connecting block is fixedly connected to the release rod via a fastener. A positioning plate is fixedly connected to each of the lateral sides of the connecting block, and the positioning plates are fixed against the lateral sides of the release rod. The dual piston rods, connecting blocks, and positioning plates ensure the stability of the release rod's movement and the effectiveness of force transmission.
[0007] Furthermore, six longitudinal auxiliary rods are fixed between the two transverse support rods. The six longitudinal auxiliary rods are divided into two groups and arranged symmetrically. One group of longitudinal auxiliary rods is located between longitudinal support rod one and longitudinal support rod two.
[0008] Furthermore, the release rod is located between the two longitudinal auxiliary rods or / and between the longitudinal auxiliary rod and the second longitudinal support rod.
[0009] Furthermore, the two ends of the longitudinal support rod 2 and the longitudinal auxiliary rod are fixedly connected to the transverse support rod through the fastener 2.
[0010] Furthermore, the second fixing component includes a horizontal plate and a vertical plate fixed perpendicularly to each other. Triangular plates are fixed to both sides of the horizontal and vertical plates. Both the horizontal and vertical plates have slotted holes. The horizontal and vertical plates are fixed to the transverse support rod and the longitudinal support rod, respectively, by fasteners passing through the slotted holes. The horizontal and vertical plates are also fixed to the transverse support rod and the longitudinal auxiliary rod, respectively, by fasteners passing through the slotted holes. The second fixing component with slotted holes allows for fine-tuning of the positions of the longitudinal support rod and the longitudinal auxiliary rod, enhancing the tooling's adaptability to different production needs.
[0011] Furthermore, sensors are respectively installed on both sides of the rotary joint, and the sensors are fixed on the second longitudinal support rod. Installed on both sides of the rotary joint, these sensors are used to detect the position of the tooling or the mattress, improving automation level and positioning accuracy, and ensuring production continuity.
[0012] Furthermore, the lower ends of the horizontal support rod, longitudinal support rod one, longitudinal support rod two, horizontal auxiliary rod, and longitudinal auxiliary rod are all provided with downward-facing T-slots. The magnetic attractor is fixedly connected to the T-slot by fastener three. The T-slot fixing of the magnetic attractor facilitates adjustment of its position to adapt to mattresses of different sizes or with different internal structures, thus optimizing the adsorption effect.
[0013] Furthermore, protective plates are fixedly connected to the outer sides of both the transverse support rod and the longitudinal support rod, and adjacent protective plates are fixedly connected to each other. These protective plates protect the edges of the tooling frame, preventing collision damage, extending service life, and increasing operational safety.
[0014] Compared with existing technologies, the technical advantages of this invention are: significantly reducing production line downtime and rework due to mattress shaking or falling; significantly improving product qualification rate and reducing scrap losses caused by transport damage; and facilitating integration with automated production lines through cylinder drive and sensor monitoring, enabling efficient and continuous transport operations.

One group of longitudinal auxiliary rods 5 is located between longitudinal support rod 2 and longitudinal support rod 2 and longitudinal support rod 3. There are two release rods 11 located between the two longitudinal auxiliary rods 5 or between the longitudinal auxiliary rod 5 and longitudinal support rod 2 and longitudinal support rod 3. The preferred release rod 11 consists of four rods, arranged in two symmetrical groups. One of the two rods in each group is located between the two longitudinal auxiliary rods 5, and the other is located between the longitudinal auxiliary rod 5 and the second longitudinal support rod 3. The two ends of the second longitudinal support rod 3 and the second longitudinal auxiliary rod 5 are fixedly connected to the transverse support rod 1 via fasteners 2 15.

The magnetic attachment 8 is evenly distributed below the support frame, which consists of horizontal support rod 1, vertical support rod 1, vertical support rod 2, vertical support rod 2, horizontal auxiliary rod 6, and vertical auxiliary rod 5, forming a large-area attraction plane. As long as the metal parts inside the mattress are within the attraction area, the magnetic force can be evenly applied to multiple points. The contact surface is large and uniform, completely avoiding uneven mattress sides. This eliminates the problems of unstable clamping and excessive local pressure caused by the side shape. The magnetic force is a long-range force and will not exert direct physical pressure on the mattress sides, edge filling layers, or fabric, thus avoiding the formation of indentations, tears, holes, or wrinkles. Multiple magnetic attachments 8 distributed below the support frame work simultaneously, providing a dispersed and uniform adsorption force to firmly attach the mattress to the bottom plane of the fixture. This large-area uniform adsorption force effectively resists the inertial force and vibration generated during transportation, greatly reducing the risk of the mattress shaking, shifting, or even falling. Even if there is some unevenness in the internal structure of the mattress, as long as there are enough magnetic attachment points and they are reasonably distributed, a stable adsorption force can be provided. When the fixture moves to the target position and the mattress needs to be released, the cylinder 10 pushes the release lever 11 downward. The release lever 11 acts on the upper surface of the mattress, providing a downward thrust to help overcome the magnetic attraction and achieve controllable and reliable separation between the mattress and the magnetic attachments 8.
