Description

Technical Field

[0001] This utility model relates to the field of mattress processing technology, and in particular to a damage-preventing assembly line transfer fixture. Background Technology

[0002] The production process of a spring mattress assembly line includes spring system manufacturing, filling layer processing, and edge sealing. Transfer equipment is needed to move the spring system from the spring system manufacturing section to the filling layer processing section and from the filling layer processing section to the edge sealing section.

[0003] However, existing transfer fixtures typically use pneumatic grippers. In practice, the pneumatic 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-mounted station and lowered onto the assembly table. The grippers are then released and rotated back into their original position. However, because the sides of the mattress are uneven, the gripping surface of the pneumatic grippers cannot fully conform to the mattress sides. The contact area is small, and the force points are dispersed. The pneumatic grippers may only contact the raised areas, while the recessed areas are suspended. This results in the clamping force not being evenly transmitted to the entire mattress. During transfer, the mattress is prone to shaking due to inertia or vibration, and may even fall.

[0004] Furthermore, when the pneumatic gripper comes into contact with the uneven sides, the raised parts will be subjected to excessive local pressure, which may squeeze or tear the side fabric or edge padding, forming indentations, holes or wrinkles, reducing the product qualification rate. Utility Model Content

[0005] This utility model provides a damage-resistant assembly line transfer fixture, which aims to solve the following problems that occur in the processing and transfer of spring mattresses in the prior art: (1) When transferring spring mattresses by pneumatic grippers, the spring mattresses are easy to fall off due to the small clamping force and uneven force points; (2) Due to the uneven force exerted by the pneumatic grippers on the spring mattresses, the protruding parts are prone to bear excessive local pressure, squeezing and tearing the side fabric or edge filling layer, forming indentations, holes or wrinkles, thereby reducing the product qualification rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model embodiment provides a damage-resistant assembly line transfer fixture, including:

[0008] The transfer rack is equipped with several magnetic attachments for magnetic attraction with the metal structure inside the mattress;

[0009] A detachment device for detaching the mattress magnetically attached to the transfer rack from the transfer rack.

[0010] In one embodiment, the transfer frame includes a support frame and a plurality of connecting rods disposed within the support frame; a plurality of magnetic suction elements are evenly distributed on the plurality of connecting rods.

[0011] In one embodiment, the bracket frame includes two parallel transverse support rods and two parallel end longitudinal support rods;

[0012] Several central longitudinal support rods are connected to the middle of the two transverse support rods.

[0013] In one embodiment, a plurality of longitudinal auxiliary rods are connected to the middle of the two transverse support rods; the plurality of longitudinal auxiliary rods are divided into two groups, and the two groups of longitudinal auxiliary rods are evenly distributed on both sides of the transfer frame; each group of longitudinal auxiliary rods is fixedly connected to a transverse auxiliary rod perpendicular to it.

[0014] In one embodiment, the longitudinal auxiliary rod and the transverse support rod are fixedly connected by a fastener.

[0015] In one embodiment, the fastener includes two mutually perpendicular horizontal plates and a vertical plate; the two sides of the horizontal plate and the vertical plate are connected by a triangular plate; and a strip hole is provided through the horizontal plate and the vertical plate.

[0016] In one embodiment, the detachment device includes a plurality of telescopic devices evenly spaced apart, and the output ends of the plurality of telescopic devices are provided with detachment rods arranged parallel to the plane of the transfer frame.

[0017] In one embodiment, the telescopic device is a cylinder, a piston rod is provided inside the cylinder, a connecting block is provided at the end of the piston rod, and the connecting block is fixedly connected to the release rod.

[0018] In one embodiment, the plurality of connecting rods are provided with T-shaped grooves that are arranged along their length and open downwards, and the magnetic attractor is connected to the T-shaped grooves through a second fixing member.

[0019] In one embodiment, the second fixing member is a T-shaped connecting rod, which is suspended in the T-shaped groove.

[0020] In one embodiment, a protective plate is provided around the periphery of the transfer frame, and the protective plate surrounds the outside of the mattress.

[0021] In one embodiment, a transfer joint is provided on the transfer frame, and sensors for detecting the position of the mattress are provided on both sides of the transfer joint.

[0022] The advantages of this invention compared to existing technologies are as follows: The magnetic components on the transfer frame of this invention can attract each other to the metal structure inside the mattress, allowing the mattress to firmly adhere to the transfer frame. The magnetic force generated by the magnetic components can act on multiple points on the mattress, resulting in a larger contact area and application area between the magnetic components and the mattress. This completely avoids the uneven sides of the mattress, eliminating the problems of unstable clamping and excessive local pressure caused by the side shape. Furthermore, the magnetic force is a long-range force, avoiding direct physical compression on the sides, edge filling layers, or fabric of the mattress, thus preventing indentations, tears, holes, or wrinkles. During the mattress transfer process in this embodiment, multiple magnetic components act simultaneously on the mattress, providing a dispersed and uniform adsorption force, firmly attracting the mattress to the transfer frame. This effectively resists the inertial forces and vibrations generated during transport, greatly reducing the risk of the mattress shaking, shifting, or even falling.

In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification.

[0036] Please see Figure 1 and Figure 2 A damage-resistant assembly line transfer fixture includes: a transfer frame 21 and a release device 16;

[0037] The transfer frame 21 is equipped with several magnetic attachments 8 for magnetic attraction with the metal structure inside the mattress;

[0038] The detachment device 16 is used to detach the mattress magnetically attached to the transfer frame 21 from the transfer frame 21.

[0039] In this embodiment, during use, several magnetic attachments 8 attract each other to the metal structure inside the mattress, and the mattress is firmly attached to the transfer frame 21. When the mattress is transferred to the designated position, the detachment device 16 pushes the mattress, causing the mattress to separate from the several magnetic attachments 8 on the transfer frame 21.

[0040] In this embodiment, the transfer frame 21 is equipped with a magnetic element 8, which can attract the metal structure inside the mattress. The magnetic element 8 in this embodiment is made of a magnet material that can attract metals such as iron, cobalt, and nickel. The metal structure inside the mattress is generally a metal spring or a metal support frame. Through the magnetic element 8, the mattress can be firmly attached to the transfer frame 21. The magnetic force generated by the magnetic element 8 can act on many points on the mattress, resulting in a large contact area between the magnetic element 8 and the mattress, completely avoiding uneven mattress sides. This eliminates the problems of unstable clamping and excessive local pressure caused by the side shape. Furthermore, the magnetic force is a non-contact force, which does not exert direct physical pressure on the mattress sides, edge filling layers, or fabric, avoiding indentations, tears, holes, or wrinkles. During the process of transporting the mattress using the damage-resistant assembly line transfer fixture in this embodiment, multiple magnetic components 8 act simultaneously on the mattress, providing a dispersed and uniform adsorption force to firmly attract the mattress to the transfer frame 21. This effectively resists the inertial force and vibration generated during transportation, greatly reducing the risk of the mattress shaking, shifting, or even falling.

[0041] In one embodiment, such as Figure 1 As shown, the transfer frame 21 includes a support frame and a plurality of connecting rods disposed within the support frame; the plurality of magnetic suction elements 8 are evenly distributed on the plurality of connecting rods.

[0042] In this embodiment, the frame of the bracket includes two parallel horizontal support rods 1 and two parallel longitudinal support rods 2 connected to the two ends of the horizontal support rods 1; a plurality of central longitudinal support rods 3 are connected to the middle of the two horizontal support rods 1.

[0043] The main frame consists of two parallel transverse support rods 1, which form the left and right edges of the entire fixture. Between these two transverse support rods 1, two longitudinal end support rods 2 are fixedly connected, located at both ends of the transverse support rods 1, providing longitudinal support at the ends.

[0044] In this embodiment, two central longitudinal support rods 3 are fixedly connected to the middle of the two transverse support rods 1, serving as central longitudinal supports. A transfer joint 4 is fixedly installed on the central longitudinal support rod 3, for example at its center. This transfer joint 4 can be used to connect to an external moving device, such as a robotic arm or transfer system, to achieve flexible rotation and position adjustment of the tooling.

[0045] In one embodiment, a plurality of longitudinal auxiliary rods 5 are connected to the middle of the two transverse support rods 1. The plurality of longitudinal auxiliary rods 5 are divided into two groups, and the two groups of longitudinal auxiliary rods 5 are evenly distributed on both sides of the transfer frame 21; each group of longitudinal auxiliary rods 5 is fixedly connected to a transverse auxiliary rod 6 perpendicular to it.

[0046] Specifically, a set of longitudinal auxiliary rods 5 is provided between each pair of end longitudinal support rods 2 and middle longitudinal support rods 3. Each set of longitudinal auxiliary rods 5 includes at least two longitudinal auxiliary rods 5. These longitudinal auxiliary rods 5 are parallel to the end longitudinal support rods 2 and the middle longitudinal support rods 3, further enhancing the overall rigidity of the transfer frame 21.

[0047] In this embodiment, six longitudinal auxiliary rods 5 are fixedly connected between the two transverse support rods 1. These six longitudinal auxiliary rods 5 are evenly divided into two groups and arranged symmetrically. One group of longitudinal auxiliary rods 5 is located between the end longitudinal support rod 2 and the middle longitudinal support rod 3 closest to it, and is evenly distributed, for example, at equal intervals. The other group is located between the end longitudinal support rod 2 and the middle longitudinal support rod 3 on the other side. This arrangement further increases the distribution density and adsorption area of ​​the magnetic components 8, and improves the stable adsorption capacity for the mattress.

[0048] In a further embodiment, two transverse auxiliary rods 6 are fixedly connected between each pair of end longitudinal support rods 2 and middle longitudinal support rods 3.

[0049] The upper end of the longitudinal secondary rod 5 is fixedly connected to its nearest transverse secondary rod 6 via a fixing member 2 7, forming a more stable grid structure. The fixing member 2 7 can be, for example, an L-shaped bracket or a connecting plate, to fix the longitudinal secondary rod 5 and the transverse secondary rod 6.

[0050] In this embodiment, several magnetic attractors 8 are fixedly connected to the bottom surface (lower end surface) of the transverse support rod 1, the end longitudinal support rod 2, the middle longitudinal support rod 3, and the longitudinal auxiliary rod 5. These magnetic attractors 8 can be electromagnets or permanent magnets, used to attract the metal structure (such as springs or support frames) inside the mattress, thereby achieving stable movement of the mattress.

[0051] In one embodiment, both ends of the central longitudinal support rod 3 and the longitudinal secondary rod 5 are fixedly connected to the transverse support rod 1 by a fastener 15.

[0052] The fastener 15 can be configured as an L-shaped bracket or a connecting plate, etc., as in this embodiment, such as Figure 3As shown, the fastener 15 includes two mutually perpendicular horizontal plates 1501 and vertical plates 1502; the two sides of the horizontal plates 1501 and the vertical plates 1502 are connected by triangular plates 1504; and strip holes 1503 are provided through the horizontal plates 1501 and the vertical plates 1502.

[0053] The strip holes 1503 on the horizontal plate 1501 and the vertical plate 1502 are also perpendicular to each other. Taking the central longitudinal support rod 3 in this embodiment as an example, the horizontal plate 1501 is attached to the central longitudinal support rod 3, and the vertical plate 1502 is attached to the transverse support rod 1. Bolts pass through the strip holes 1503 on the horizontal plate 1501 and are fixedly connected to the central longitudinal support rod 3. Bolts also pass through the strip holes 1503 on the vertical plate 1502 and are connected to the transverse support rod 1, thereby fixing the central longitudinal support rod 3 and the transverse support rod 1 together. The strip holes 1503 are designed as elongated strips, which facilitates fine-tuning of the position of the central longitudinal support rod 3 during assembly, enhancing the adaptability of the tooling to different production needs.

[0054] In one embodiment, such as Figure 2 As shown, the detachment device 16 includes several telescopic devices arranged at even intervals, and the output ends of the several telescopic devices are provided with detachment rods 11 parallel to the plane of the transfer frame 21.

[0055] The output end of the telescopic device extends and retracts, thereby moving the release lever 11. During the transfer of the mattress, the output end is in a retracted state, while when it is necessary to separate the mattress from the transfer frame 21, the output end is in an extended state, causing the release lever 11 to extend outward and push the mattress and transfer frame 21 apart.

[0056] In this embodiment, the telescopic device is a cylinder 10, on which a piston rod 12 is provided. A connecting block 13 is provided at the end of the piston rod 12, and the connecting block 13 is fixedly connected to the release rod 11. The telescopic movement of the piston rod 12 causes the release rod 11 to move.

[0057] In a further embodiment, the cylinder 10 is a dual-piston cylinder, which has two parallel piston rods 12, the ends of which are fixedly connected to the same connecting block 13. This dual-piston rod 12 design provides more stable linear motion.

[0058] The connecting block 13 is securely connected to the release rod 11 by bolts. For example... Figure 4As shown, a positioning plate 14 is fixedly connected to both sides of the connecting block 13. The edges of the positioning plate 14 are tightly abutted against the sides of the release rod 11 and then fixed. The combined action of the positioning plate 14 and the connecting block 13 further ensures the stability of the release rod 11 during the pushing of the mattress and the effective transmission of force, avoiding tilting or shaking.

[0059] In a further embodiment, such as Figure 1 As shown, a fixed rod 9 perpendicular to the two transverse auxiliary rods 6 is provided on the side away from the longitudinal auxiliary rod 5, and the cylinder 10 is fixedly mounted on the fixed rod 9. This structure creates a distance between the fixed rod 9 and the longitudinal auxiliary rod 5, so that when the transfer frame 21 magnetically attracts the mattress, the release rod 11 can retract into the groove formed by the longitudinal auxiliary rod 5. The lower end face of the release rod 11 is higher than the lower end face of the magnetic attractor 8, and the release rod 11 will not interfere with the mattress. When it is necessary to detach the mattress from the transfer frame 21, the piston rod 12 extends outward, driving the release rod 11 to move. The release rod 11 acts on the mattress, overcoming the attraction of the magnetic attractor 8, and separating the mattress from the transfer frame 21.

[0060] In this embodiment, four sets of release devices 16 are provided, and four corresponding release rods 11 are provided. Figure 1 As shown, the four release levers 11 are also divided into two symmetrical groups (two levers in each group). In one group, one release lever 11 is located, for example, between two adjacent longitudinal sub-lever 5. The other release lever 11 is located between the longitudinal sub-lever 5 and the central longitudinal support lever 3. This arrangement ensures that the release levers 11 can cover more area of ​​the mattress, providing a more even downward force, thereby achieving more effective and reliable separation between the mattress and the magnetic closure 8.

[0061] In one embodiment, such as Figure 5 and Figure 6 As shown, the plurality of connecting rods are provided with T-shaped grooves 18 arranged along their length and opening downwards, and the magnetic suction member 8 is connected to the T-shaped grooves 18 through the fixing member 3 19.

[0062] Specifically, the bottom surfaces of the transverse support rod 1, the end longitudinal support rod 2, the middle longitudinal support rod 3, and the longitudinal auxiliary rod 5 are all provided with T-slots 18, and the magnetic suction component 8 is connected to the T-slots 18 through the fixing component 3 19.

[0063] The fixing component 19 is a T-shaped connecting rod 191, which is suspended in the T-shaped groove 18.

[0064] The T-shaped connecting rod 191 cooperates with the T-shaped groove 18 and can be suspended in the T-shaped groove 18. The T-shaped connecting rod 191 can slide in the T-shaped groove 18. The operator can slide the magnetic suction piece 8 along the T-shaped groove 18 to flexibly change its installation position to adapt to different sizes of mattresses or different layouts of their internal metal structures, thereby optimizing the adsorption effect and improving versatility.

[0065] In a further embodiment, the T-shaped connecting rod 191 is interference-fitted with the T-shaped groove 18. Specifically, the T-shaped connecting rod 191 is interference-fitted with the opening of the T-shaped groove 18 so that when the external force is small, the T-shaped connecting rod 191 can be fixed in the T-shaped groove 18, preventing the position of the magnetic suction component 8 from moving due to equipment shaking during the unloaded moving transfer frame 21.

[0066] In one embodiment, such as Figure 1 As shown, a protective plate 20 is provided around the periphery of the transfer frame 21. When the mattress is attached to the transfer frame 21, the protective plate 20 surrounds the periphery of the mattress.

[0067] The two adjacent protective plates 20 are also fixedly connected to each other to form a continuous protective edge. These protective plates 20 are made of high-strength plastic or thin metal sheets, and their main function is to protect the edge of the tooling frame and prevent collisions and friction during transportation or operation, thereby avoiding damage to the transfer frame 21, extending the service life of the entire damage-proof assembly line transfer tooling, and also increasing the safety of operation.

[0068] In one embodiment, sensors 17 for detecting the position of the mattress are respectively provided on both sides of the longitudinal direction of the transfer joint 4.

[0069] Sensor 17 includes, but is not limited to, photoelectric sensors and infrared sensors, used to detect the mattress's position, improve automation and positioning accuracy, and ensure production continuity.

[0070] The specific implementation process of the damage-resistant assembly line transfer fixture in this embodiment is as follows: The robotic arm is connected to the transfer joint 4, driving the entire damage-resistant assembly line transfer fixture to move; the piston rod 12 of the cylinder 10 retracts inward, and the release rod 11 is higher than the lower end plane of the magnetic component 8. The transfer frame 21 covers the entire mattress from above, so that the entire mattress is located in the space surrounded by the protective plate 20. The sensor 17 detects that the mattress is in place. At this time, the transfer frame 21 is in contact with the mattress, and several magnetic components 8 attract each other with the metal structure inside the mattress, so that the mattress is magnetically attracted to the transfer frame 21. Then, the robotic arm drives the entire damage-resistant assembly line transfer fixture to move. After moving to the designated position, the piston rods 12 of multiple cylinders 10 extend outwards simultaneously. The piston rods 12 drive the release rods 11 to extend downwards. The release rods 11 interact with the mattress, overcoming the magnetic attraction between the magnetic components 8 and the metal parts inside the mattress, separating the mattress from several magnetic components 8. Then, the robotic arm drives the damage-resistant assembly line transfer fixture to the initial position, and the piston rods 12 drive the release rods 11 to retract inwards. The release rods 11 are higher than the lower end plane of the magnetic components 8, waiting for the next mattress transfer.

[0071] In this embodiment, the magnetic components 8 on the transfer frame 21 can attract each other to the metal structure inside the mattress, allowing the mattress to firmly adhere to the transfer frame 21. The magnetic force generated by the magnetic components 8 can act on multiple points on the mattress, resulting in a large contact area between the magnetic components 8 and the mattress, completely avoiding the uneven sides of the mattress and eliminating the problems of unstable clamping and excessive local pressure caused by the side shape. Moreover, 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. During the mattress transfer process in this embodiment, multiple magnetic components 8 act on the mattress simultaneously, providing a dispersed and uniform adsorption force, firmly attracting the mattress to the transfer frame 21, thereby effectively resisting the inertial forces and vibrations generated during transportation, greatly reducing the risk of the mattress shaking, shifting, or even falling.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
