Description

Technical Field

[0001] The utility model relates to the technical field of mattress processing, in particular to a bed net frame grabbing and moving mechanism. Background Art

[0002] Spring mattresses have become the mainstream filling mattresses because of their relatively uniform distribution of support for the human body, which not only provides sufficient support but also ensures a reasonable physiological curvature of the spine. At present, the main materials for making spring mattresses are frames and spring cores. Among them, when assembling the frame, the steel wire needs to be bent into a frame shape, and then the two free ends of the steel wire need to be pressed and fixed together through a sleeve to form the required frame. During the frame assembly process, the bent steel wire needs to be fed into the sleeve, and after the sleeve is pressed and fixed, the frame needs to be fed into the unloading station. Therefore, how to provide a moving mechanism with good stability is an urgent problem that needs to be solved in the automated assembly of the frame. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a bed net frame grabbing and moving mechanism, which can improve the stability of the frame movement.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a bed net frame grabbing and moving mechanism, including

[0005] base;

[0006] A lifting mechanism is mounted on the base, comprising a lifting frame plate capable of being lifted and lowered by a lifting drive member;

[0007] A transverse movement mechanism is mounted on the lifting frame plate, comprising a transverse movement base plate capable of moving forward and backward under the action of a transverse movement driving member;

[0008] The grabbing mechanism is installed on the transverse moving base plate, and includes a first grabbing base plate and a second grabbing base plate arranged in sequence along the front-to-back direction. The first grabbing base plate and the second grabbing base plate are respectively provided with a first grabbing member and a second grabbing member for grabbing the frame, and the first grabbing member and the second grabbing member can respectively grab the three perpendicular sides of the frame.

[0009] The beneficial effects of the bed net frame grabbing and moving mechanism of the utility model are:

[0010] The movement of the grasping mechanism in the front-to-back direction is realized by the setting of the transverse movement mechanism, and the movement of the grasping mechanism in the up-down direction is realized by the setting of the lifting mechanism, which is conducive to the grasping mechanism driving the frame to move horizontally (front-to-back direction) or vertically (up-down direction) to meet the movement and circulation of the frame in different workstations; in the grasping mechanism, the position layout of the first grasping substrate and the second grasping substrate and the cooperation of the first grasping member and the second grasping member can grasp at multiple points of the frame, thereby improving the stability of the frame grasping and ensuring the stable movement of the frame.

[0011] Furthermore, the first gripping member includes a connecting plate, on which is provided a pair of first pneumatic clamps that can move toward or away from each other in the left and right directions, and the pair of first pneumatic clamps can respectively grip the same side of the frame.

[0012] Since the two ends of the bent steel wire need to be joined together through a sleeve during the production of the frame, in actual application, the first gripping member is arranged near the position where the two ends of the steel wire are joined. Then, the two first pneumatic grippers can respectively grip the two ends of the steel wire on the same side of the frame, so as to facilitate the subsequent joining operation of the two ends of the steel wire through the sleeve. The first pneumatic grippers move toward or away from each other to facilitate the insertion of the two ends of the steel wire into the sleeve. In other words, the first gripping member can not only grip the frame, but also grab the two ends of the steel wire and feed them into the sleeve.

[0013] Specifically, the second gripper includes two second pneumatic grippers mounted sequentially along the left-right direction on the second gripper base. These two second pneumatic grippers can respectively grip two parallel sides of the frame, with the second pneumatic grippers and the first pneumatic grippers gripping in a direction perpendicular to each other. While the first gripper grips on the same side of the frame, the second gripper, through its two second pneumatic grippers, grips on two parallel sides of the frame. This allows the first and second grippers to coordinate and achieve a three-sided grip on the frame, improving gripping stability.

[0014] Specifically, the transverse drive assembly includes a drive motor, a synchronous shaft, a driving gear, a driven gear, and a toothed belt. The synchronous shaft is mounted on the lifting frame and rotates under the influence of the drive motor. The driving gear is fixedly mounted on the synchronous shaft, with a toothed belt looped between it and the driven gear. The toothed belt is provided with a connector for connecting to the transverse base. The coordination of the driving gear, driven gear, and toothed belt ensures more stable transverse movement of the connector, thereby enhancing the stability of the transverse base and the gripping mechanism.

[0015] Furthermore, the transverse drive component also includes a clamping portion, which comprises a pair of cantilever arms and a pressure wheel. The cantilever arms are disposed on either side of the toothed belt, with one end of the cantilever arm fixedly attached to the lifting frame and the other end suspended in the air. The suspended ends of the cantilever arms are connected to a fixed shaft. The pressure wheel is mounted on the fixed shaft and can press against the toothed belt. The clamping portion tensions the toothed belt, ensuring stable transmission of the toothed belt and facilitating stable movement of the transverse substrate.

[0016] Furthermore, the pressure wheel includes a wheel body, and two side edges of the wheel body are respectively provided with limit lift edges for limiting the position of the toothed belt. When the toothed belt is driving, the toothed belt is always located between the two limit lift edges to prevent the toothed belt from escaping from the pressing force of the pressure wheel.

[0017] Furthermore, the lifting frame is provided with guide rails arranged in the front-to-back direction, and the traverse base plate is connected to a traverse guide plate that can move along the guide rails. The cooperation between the traverse guide plate and the guide rails further improves the stability of the traverse base plate in traverse movement along the lifting frame.

[0018] Furthermore, the lifting frame plate includes a hollow frame plate body, and the frame plate body is provided with a lifting base plate for connecting the lifting drive component.

[0019] Specifically, the lifting drive comprises a fixed plate, an elevator, and guide rods. The fixed plate is fixed to the base, the elevator is mounted on the fixed plate, and its ball screw is connected to the lifting base. Multiple guide rods are provided, each with one end fixed to the lifting base and the other end passing through the fixed plate. The guide rods are provided to guide the up and down movement of the lifting frame.

[0020] Furthermore, the lifting drive member also includes a guide plate, which is located below the fixed plate and is fixed to the base. The guide plate is provided with guide through holes corresponding to the ball screw and the guide rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0034] Example

[0035] See attached Figure 1-2 As shown, a bed net frame grabbing and moving mechanism of the present invention includes a base 1, a lifting mechanism 2, a transverse mechanism 3, and a grabbing mechanism 4, wherein the lifting mechanism 2 is installed on the base 1, and includes a lifting frame plate 22 that can be lifted and moved under the action of a lifting drive 21. The transverse mechanism 3 is installed on the lifting frame plate 22, and includes a transverse substrate 32 that can move back and forth under the action of a transverse drive 31. The grabbing mechanism 4 is installed on the transverse substrate 32, and includes a first grabbing substrate 41 and a second grabbing substrate 42 that are sequentially arranged along the front and back directions, and the first grabbing substrate 41 and the second grabbing substrate 42 are respectively provided with a first grabbing member 43 and a second grabbing member 44 for grabbing the frame, and the first grabbing member 43 and the second grabbing member 44 can respectively grab three sides of the frame 5 that are perpendicular to each other.

[0036] The movement of the grasping mechanism 4 in the front-to-back direction is realized by the setting of the transverse movement mechanism 3, and the movement of the grasping mechanism 4 in the up-down direction is realized by the setting of the lifting mechanism 2, which is conducive to the grasping mechanism 4 driving the frame 5 to move horizontally (front-to-back direction) or vertically (up-down direction) to meet the movement flow of the frame 5 in different workstations; in the grasping mechanism 4, the position layout of the first grasping substrate 41 and the second grasping substrate 42 and the cooperation of the first grasping member 43 and the second grasping member 44 can grasp at multiple points of the frame 5, thereby improving the stability of the grasping of the frame 5 and ensuring the stable movement of the frame 5.

[0037] Since the two ends (two free ends) of the bent steel wire need to be joined together through a sleeve during the processing of the frame 5, in order to improve the performance of the grabbing mechanism 4, in some embodiments, the first grabbing member 43 is arranged on the side close to the free end of the steel wire, and the first grabbing member 43 can grab both ends of the steel wire at the same time. Figure 2-3 As shown, the first gripping member 43 includes a connecting plate 431 fixed to the first gripping base plate 41. A pair of first pneumatic grippers 432 are mounted on the connecting plate 431 and can move toward or away from each other in the left-right direction. The pair of first pneumatic grippers 432 can respectively grasp the two ends of a steel wire located on the same side of the frame 5. The movement of the two first pneumatic grippers 432 toward or away from each other ensures that the two first pneumatic grippers 432 respectively grasp the two ends of the steel wire, allowing the subsequent intubation operation to simultaneously insert both ends of the steel wire into the cannula.

[0038] For example; with the cooperation of the lifting mechanism 2 and the transverse movement mechanism 3, the transverse movement base plate 32 is moved to the free end of the bent steel wire; then the two first pneumatic clamps 432 respectively grasp the two free ends of the steel wire, and then the two first pneumatic clamps 432 move back to back to drive the two free ends of the steel wire away from each other until space is left between the two free ends of the steel wire for placing the sleeve; when the sleeve is in place, the two first pneumatic clamps 432 move toward each other to drive the two free ends of the steel wire to approach each other, and are inserted into the sleeve from both ends to complete the intubation action.

[0039] Since the first grabbing member 432 only grabs one side of the frame 5, the grabbing stability of the frame 5 is poor. Therefore, in some embodiments, see the attached Figure 3As shown, the second gripping member 44 includes two second pneumatic grippers 441 mounted sequentially along the left-right direction on the second gripping base 42. The two second pneumatic grippers 441 can respectively grip two parallel sides of the frame, and the gripping directions of the second pneumatic grippers 441 and the first pneumatic grippers 432 are perpendicular to each other. In other words, the two second pneumatic grippers 441 respectively grip two sides perpendicular to the side gripped by the first pneumatic grippers 432. This achieves three-sided gripping of the frame 5, improving gripping stability.

[0040] Furthermore, along the front-to-back direction, the gripping position of the second gripping member 44 should be as far away from the first gripping member 41 as possible to ensure uniform gripping force on the frame 5 .

[0041] In some embodiments, see Appendix Figure 4 As shown, the lifting frame plate 22 includes a hollow frame plate body 221 , and a lifting base plate 222 for connecting the lifting driving member 21 is provided on the frame plate body 221 .

[0042] See attached Figure 5 As shown, the lifting drive 21 includes a fixed plate 211, an elevator 212, and a guide rod 213. The fixed plate 211 is fixed to the base 1. The elevator 212 is mounted on the fixed plate 211, and its ball screw is connected to the lifting base plate 222. There are multiple guide rods 213, each of which has one end fixed to the lifting base plate 222 and the other end extending through the fixed plate 211. The elevator 212 drives the lifting base plate 222 up and down, thereby driving the entire lifting frame 22 up and down. The guide rods 213 guide the lifting direction of the lifting frame 22. Furthermore, the lifting drive 21 also includes a guide plate 214. The guide plate 214 is located below the fixed plate 211 and fixed to the base 1. It is provided with guide holes corresponding to the ball screws and guide rods 213. The guide holes guide the piston rod and the guide rods 213.

[0043] In some embodiments, the frame plate body 221 is provided with guide rails arranged in the front-to-back direction, and the traverse base plate 32 is connected to a traverse guide plate 321 that can move along the guide rails. The cooperation between the traverse guide plate 321 and the guide rails further improves the stability of the traverse base plate 32 in traverse movement along the lifting frame plate 22.

[0044] In some embodiments, see Appendix Figure 6As shown, the traverse drive 31 includes a drive motor 311, a synchronizing shaft, a driving gear 312, a driven gear, and a toothed belt 313. The synchronizing shaft is mounted on the lifting frame 22 and is rotated by the drive motor 311. The driving gear 312 is fixedly mounted on the synchronizing shaft, with a toothed belt 313 wound between it and the driven gear. The toothed belt 313 is provided with a connecting base for connecting to the traverse base 32. The coordination of the driving gear 312, the driven gear, and the toothed belt 313 ensures more stable traverse movement of the connecting base, thereby enhancing the traverse stability of the traverse base 32 and the gripping mechanism 4.

[0045] Furthermore, the transverse drive member 31 also includes a pressing portion, which comprises a pair of cantilevers 314 and a pressure wheel 315. The cantilevers 314 are disposed on either side of the toothed belt 313, with one end of the cantilevers 314 fixed to the elevating baseplate 222 and the other end suspended in the air. The suspended ends of the cantilevers are connected to a fixed shaft. The pressure wheel 315 is mounted on the fixed shaft and can press against the toothed belt 313. The provision of the pressing portion allows the toothed belt 313 to be tensioned, ensuring stable transmission of the toothed belt 313 and facilitating stable movement of the transverse baseplate 32.

[0046] Furthermore, the pressure wheel 315 includes a wheel body, and the two side edges of the wheel body are respectively provided with limit lift edges for limiting the position of the toothed belt 313. When the toothed belt 313 is driving, the toothed belt 313 is always located between the two limit lift edges to prevent the toothed belt 313 from escaping the pressure of the pressure wheel 315.

[0047] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
