Description

Technical Field

[0001] This utility model relates to the field of bed net manufacturing equipment technology, and in particular to an automatic material turning and clamping device for support springs. Background Technology

[0002] Spring mattresses, as a widely used type of mattress in modern times, have become the choice of most consumers due to their advantages in support, breathability, and durability. Their core structure consists of a spring system and a filling layer. To improve edge support and structural stability, spring mattresses have support springs installed along all four sides. These support springs are typically distributed longitudinally along the four sides of the mattress, strengthening the support density in the edge area and preventing the edges from collapsing or deforming due to excessive localized pressure.

[0003] Industry standards require that the support springs form a continuous and uniform mechanical distribution along the four sides of the mattress, and their axial deviation must be controlled within ±1.5mm to ensure that the edge area has a linear support strength of not less than 1500N per linear meter.

[0004] In the current manufacturing process of spring mattresses, the support springs are placed one by one on the side of the mattress. This may result in inconsistent straight-line positioning of the support springs during placement, which will affect the boundary resistance index (BDR) compliance rate of the mattress. Moreover, placing the support springs one by one will increase processing time and extend the production cycle.

[0005] The technical content disclosed in the Chinese patent document (Publication No.: CN218087700U, Patent Name: Support Spring Feeding Equipment and Bag Spring Bed Core Edge-Banging Equipment) is as follows: The conveying direction of the fourth drive mechanism is parallel to the side of the bed core, and the gripper is located directly above the pallet. During material handling, the gripper is set parallel to the pallet. When the support spring abuts against the gripper located directly above it, the gripper attracts the support spring. Subsequently, the fifth drive mechanism operates, driving the sixth drive mechanism and the gripper to rotate so that the gripper is parallel to the side of the bed core. Then, the sixth drive mechanism operates, pushing the gripper and the support spring into the side of the bed core. The fourth drive mechanism drives the fifth drive mechanism to move, so that different support springs are placed at different positions on the side of the bed core.

[0006] As can be seen from the above implementation plan and the corresponding drawings, although its mechanical structure can achieve basic positioning function, it has two major technical defects: First, the transmission backlash of the multi-degree-of-freedom motion mechanism will cause the end effector to deflection error; second, the cycle time limitation of the intermittent feeding system makes it difficult to match the capacity requirements of high-speed production lines. These defects lead to the dual dilemma of production cycle time mismatch and insufficient product consistency in practical applications, which seriously restricts the industry's transformation to intelligent manufacturing. Utility Model Content

[0007] This utility model overcomes the shortcomings of the prior art and provides an automatic support spring flipping and clamping device. The device is equipped with a flipping mechanism and a clamping mechanism. The support spring is placed after the flipping mechanism. The positioning table of the flipping mechanism flips to fit the support spring against the side of the bed core before clamping. This makes the position of the support spring on one side of the bed core more uniform and the fit between the support spring and the bed core higher, thus resulting in a better molding effect of the product.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] An automatic material turning and clamping device with a support spring, comprising:

[0010] The flipping mechanism is equipped with a flipping table with a permanent magnet array. It achieves 90° flipping and positioning through a crank-connecting rod transmission mechanism, so that the support spring can ultimately be perpendicular to the side of the bed core.

[0011] The clamping mechanism is equipped with a multi-point synchronous positioning system, which includes two sets of clamping units that can be independently adjusted in three-dimensional space. It achieves precise clamping and fixing of the support spring and the bed core through servo drive.

[0012] Furthermore, the flipping mechanism includes a rotating support rod and a flipping crank that are coaxially fixed together, wherein the end of the flipping crank is connected to a flipping table.

[0013] Furthermore, the tilting table is provided with an adjustment slot, and an adjustment hole is provided in the adjustment slot. The tilting table is movably connected to a positioning component.

[0014] Furthermore, the positioning component includes a positioning platform with a conical column. The positioning platform can be continuously adjusted along the direction of the adjustment slot by positioning bolts.

[0015] Furthermore, the flipping mechanism is also equipped with a first motor, which is connected to a first sprocket, and one end of the rotating support rod is connected to a second sprocket. The first sprocket and the second sprocket are connected by a chain.

[0016] Furthermore, the clamping unit includes a first clamping machine and a second clamping machine. Both the first clamping machine and the second clamping machine can be adjusted in distance relative to the bed core, and the second clamping machine can be adjusted in height relative to the first clamping machine.

[0017] Furthermore, the clamping mechanism includes

[0018] The second motor is connected to the clamp displacement screw. A first slide rail is arranged parallel to the side of the clamp displacement screw. The first slide rail is slidably connected to the clamp base, and the clamp base is threadedly connected to the clamp displacement screw.

[0019] Furthermore, the clamping base is provided with a clamping protective upper seat, the clamping base is connected to the first clamping slide rail, and the first clamping slide rail is connected to the first clamping machine;

[0020] The inner side of the clamping and protective upper seat is connected to the second slide rail, the second slide rail is connected to the second clamping slide rail, the second slide rail and the second clamping slide rail are perpendicular to each other, the second clamping slide rail is connected to the second clamping machine, and the clamping lifting screw is connected to the second clamping machine.

[0021] Furthermore, a third motor is provided on the clamping and protective upper seat, the third motor is connected to the clamping and lifting screw, and the clamping and lifting screw is connected to the clamping and lifting screw.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. An automatic material turning and clamping device for support springs is provided, which is equipped with a turning mechanism and a clamping mechanism. The support springs are placed after the turning mechanism. The positioning table of the turning mechanism turns over to fit the support springs to the side of the bed core before clamping. This makes the position of the support springs on one side of the bed core more uniform and the fit between the support springs and the bed core higher, thus making the product molding effect better.

[0024] 2. The contact surface of the tilting table is equipped with a magnetic array to ensure that the support spring is in contact with the tilting table. This also prevents the support spring from falling off when the tilting table rotates, making the support spring more stable when it is moved. It also increases the stability of the subsequent contact position between the support spring and the bed core. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] like Figures 1 to 4 As shown, an automatic material turning and clamping device for support springs includes a clamping mechanism 2 and a turning mechanism 1. The turning mechanism 1 is equipped with a turning table 104. After the support springs are sent onto the turning table 104, the turning table 104 is turned over by a crank-connecting rod mechanism, so that the support springs are vertically attached to the side of the bed core. The clamping mechanism 2 then clamps and fixes the support springs and the bed core at multiple points synchronously. Therefore, the support springs are arranged and placed on the turning table 104 and then uniformly attached to the side of the bed core. Compared with the traditional method of attaching the support springs to the side of the bed core one by one and then clamping and fixing them, this method makes the position of a row of support springs more uniform and the fit between the support springs and the bed core higher, thus resulting in a better product molding effect. Furthermore, attaching all the support springs to the side of the bed core at once and then clamping them also makes the clamping efficiency higher and improves the production efficiency of the equipment.

[0033] The flipping mechanism 1 includes a first motor 101 connected to a first sprocket 1011. One end of a rotating support rod 102 is connected to a second sprocket 1021. The first sprocket 1011 and the second sprocket 1021 are connected by a chain. The rotating support rod 102 is connected to a flipping crank 103. A flipping table 104 is connected to the end of the flipping crank 103 away from the rotating support rod 102. When the rotating support rod 102 rotates, the flipping table 104 achieves stepless positioning within the range of 0° horizontal to 90° vertical. The contact surface of the flipping table 104 is provided with a magnetic array to ensure that the support spring adheres to the flipping table 104. The flipping table 104 is provided with an adjustment slot 1041. 1. An adjustment elongated hole 1042 is provided. The flipping table 104 is movably connected to a positioning component 105. The positioning component 105 includes a positioning platform 1051. A conical column 10511 is provided on the positioning platform 1051. The conical head of the conical column 10511 facilitates the insertion of the support spring into the conical column 10511. In this embodiment, the positioning platform 1051 is magnetic. After the magnetic block 3064 moves the support spring onto the positioning platform 1051, the magnetic block 3064 is demagnetized. Therefore, the support spring is attracted by the magnetic force of the positioning platform 1051. Because the positioning platform 1051 is magnetic, the support spring will not fall off the positioning platform 1051 during the flipping process of the flipping table 104.

[0034] The positioning platform 1051 can be continuously adjusted along the direction of the adjusting groove 1041 by positioning bolt 1052. Therefore, the position and number of support springs can be adjusted to adjust the size between the positioning platforms 1051 each day, so that the flipping mechanism 1 can adapt to more support springs of different sizes, making the application range of the device wider.

[0035] The clamping mechanism 2 includes a second motor 201, which is connected to a clamping displacement screw 2011. A first slide rail 202 is arranged parallel to the side of the clamping displacement screw 2011. The first slide rail 202 is slidably connected to a clamping base 203, which is threadedly connected to the clamping displacement screw 2011. A clamping protective upper seat 2031 is provided on the clamping base 203. The clamping base 203 is connected to a first clamping slide rail 2041, which is connected to a first clamping machine 204. A second slide rail 206 is connected to the inner side of the clamping protective upper seat 2031. The second slide rail 206 is connected to a second clamping slide rail 2071, which is connected to a second clamping machine 207. Therefore, both the first clamping machine 204 and the second clamping machine 207 can move back and forth, so that when clamping the support spring of a bed core with slight dimensional deviations, the back and forth position can also be adjusted.

[0036] The second slide rail 206 and the second clamping slide rail 2071 are perpendicular to each other. The clamping lifting screw 2051 is connected to the second clamping machine 207. A third motor 205 is installed on the clamping protective upper seat 2031. The third motor 205 is connected to the clamping lifting screw 2051, and the clamping lifting screw 2051 is also connected to the clamping lifting screw 2051. The second slide rail 206 is used to adjust the height of the second clamping machine 207. By adjusting the height distance between the first clamping machine 204 and the second clamping machine 207, the first clamping machine 204 and the second clamping machine 207 can clamp bed cores of different thicknesses.

[0037] Driven by the second motor 201, the first clamping machine 204 and the second clamping machine 207 can move along the side of the bed core, and the first clamping machine 204 and the second clamping machine 207 can simultaneously fix the upper and lower lines of the support spring to the frame of the bed core, thus greatly improving production efficiency.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
