Description

Technical Field

[0001] The present application relates to the technical field of diaphragm preparation devices, and more particularly, to a rubber band sleeving device. Background Art

[0002] During industrial production, the process of bundling workpieces with rubber bands is often involved. For example, during the preparation of diaphragms, it is usually necessary to put rubber bands on the ends of the core rolls. However, the current bundling methods are all carried out manually, which is time-consuming and laborious. Utility Model Content

[0003] Based on the above deficiencies, the present application provides a rubber band sleeving device to more conveniently bundle workpieces with rubber bands.

[0004] The present application is implemented as follows:

[0005] An example of the present application provides a rubber band sleeving device, including a frame, a feeding mechanism, and a rubber band sleeving mechanism. The feeding mechanism includes a first vibrating feeding box and a vibrating screening plate arranged on the frame. The first discharge port of the first vibrating feeding box is located above the vibrating screening plate. The first vibrating feeding box is provided with a first baffle. There is a first gap between the bottom end of the first baffle and the bottom plate of the first vibrating feeding box to form the first discharge port. The first vibrating feeding box vibrates to make the rubber bands in the first vibrating feeding box pass through the first discharge port and fall into the vibrating screening plate. The vibrating screening plate vibrates to separate multiple rubber bands into single rubber bands. The rubber band sleeving mechanism can selectively grab a single rubber band and sleave the rubber band outside the workpiece.

[0006] In the above implementation process, using the above rubber band sleeving device, rubber bands can be loaded into the first vibrating feeding box for storage, and the first vibrating feeding box can convey the rubber bands towards the direction of the first discharge port through vibration. Since there is a first baffle at the first discharge port of the first vibrating feeding box, a small amount of rubber bands can pass through the first gap between the first baffle and the bottom plate and fall onto the vibrating screening plate. The vibrating screening plate can vibrate to make the small amount of rubber bands falling onto the vibrating screening plate move irregularly, so that the rubber bands are separated from each other, facilitating the use of the rubber band sleeving device to grab a single rubber band and sleave the rubber band on the surface of the workpiece for bundling. Using the above rubber band sleeving device, manual operation is not required during the process of conveying rubber bands and grabbing rubber bands for bundling, and the rubber band sleeving operation can be automatically performed, which can improve the convenience and efficiency of the rubber band sleeving operation.

[0007] In an alternative embodiment, the feeding mechanism further includes a second vibrating feeding box. The second discharge port of the second vibrating feeding box is located above the first vibrating feeding box. The second vibrating feeding box is provided with a second baffle. There is a second gap between the bottom end of the second baffle and the bottom plate of the second vibrating feeding box to form the second discharge port. The second vibrating feeding box vibrates to enable the rubber bands in the second vibrating feeding box to pass through the second discharge port and fall into the first vibrating feeding box.

[0008] In the above implementation process, by setting two - stage vibrating feeding boxes in the feeding mechanism, a large number of rubber bands can be stored in the second vibrating feeding box. The second vibrating feeding box continuously transports a small amount of rubber bands from the second discharge port to the first vibrating feeding box. The first vibrating feeding box can continuously transport a small amount of rubber bands to the vibrating screening plate again, so that the vibrating screening plate can vibrate and separate the rubber bands stacked together to obtain dispersed single rubber bands, enabling the rubber - band sleeving mechanism to grab the screened single rubber bands and sleeve them outside the workpiece for bundling.

[0009] In an alternative embodiment, the bottom plate of the second vibrating feeding box is inclined downward in the direction towards the second discharge port; and / or, the bottom plate of the first vibrating feeding box is inclined downward in the direction towards the first discharge port.

[0010] In the above implementation process, the bottom plate of the second vibrating feeding box is inclined downward in the direction towards the second discharge port, and the bottom plate of the first vibrating feeding box is inclined downward in the direction towards the first discharge port, which can make the rubber bands in the vibrating feeding box move towards the discharge port direction, improving the conveying efficiency.

[0011] In an alternative embodiment, the feeding mechanism further includes a conveyor belt. One end of the conveyor belt is connected to the first discharge port of the first vibrating feeding box, and the other end of the conveyor belt is located above the vibrating screening plate. The conveyor belt is used to transport the rubber bands passing through the first discharge port to above the vibrating screening plate so that the rubber bands fall into the vibrating screening plate.

[0012] In the above implementation process, by setting a conveyor belt at the first discharge port of the first vibrating feeding box, the conveyor belt can be used to gradually transport the rubber bands passing through the first discharge port to the vibrating screening plate.

[0013] In an alternative embodiment, the rubber - band sleeving mechanism includes a grasping assembly; the grasping assembly includes an identification camera, a processor, a first moving member, and a first gripper. The first moving member is arranged on the frame and is located above the vibrating screening plate; the identification camera identifies the position and shape of the target rubber band on the vibrating screening plate, sends a signal to the first moving member through the processor, and the first moving member receives the signal and drives the first gripper to the target position. The first gripper expands to sleeve the target rubber band outside the first gripper.

[0014] In the above implementation process, an identification camera is set at the vibration screening disk, and the identification camera can be used to identify the position and state of each rubber band screened by the vibration screening disk. The processor analyzes whether the shape and position of the rubber band in the picture obtained by the identification camera are suitable for grasping, and sends the position signal of the target rubber band suitable for grasping to the first movable member. At this time, the first movable member located above the vibration screening disk can drive the first gripper to move to the target position, the first gripper extends into the target rubber band and then stretches the target rubber band, and sets the target rubber band outside the first gripper.

[0015] In an optional embodiment, the grabbing assembly further includes a cache gripper, which is disposed outside the vibrating screening disk, and the first movable member can selectively drive the first gripper to sleeve the stretched target rubber band outside the cache gripper.

[0016] In the above implementation process, a buffer gripper is also provided outside the vibrating screening disk. The first movable member can drive the first gripper to put the target rubber band to be grasped outside the buffer gripper, and then the first movable member drives the first gripper to move to the vibrating screening disk to facilitate grasping a new target rubber band again.

[0017] In an optional embodiment, the rubber band wrapping mechanism also includes a rubber band wrapping assembly, which includes a robotic arm and a second gripper arranged on the robotic arm. The robotic arm can selectively drive the second gripper to extend into a target rubber band wrapped around the cache gripper, and the second gripper expands outward or the cache gripper contracts inward to wrap the target rubber band around the second gripper.

[0018] In the above implementation process, the robotic arm can drive the second gripper to extend into the target rubber band at the cache gripper, and the second gripper expands outward to separate the target rubber band from the cache gripper and is sleeved on the second gripper, or the cache gripper contracts inward into the second gripper to separate the target rubber band from the cache gripper, thereby realizing the conversion of the target rubber band at the cache gripper and the second gripper, so that the robotic arm can drive the second gripper to sleeve the target rubber band outside the workpiece.

[0019] In an optional embodiment, the first gripper, the cache gripper and the second gripper each include a mounting plate and a plurality of vertically extending struts connected to the mounting plate, one end of the plurality of struts being slidably connected to the mounting plate in a direction away from each other, and the other end of the struts being used to extend into the rubber band.

[0020] In the above implementation process, when the gripper needs to grab the rubber band, at least two support rods of the corresponding gripper can be extended into the rubber band, and then multiple support rods are slid away from each other on the mounting plate to expand the rubber band outward so that the rubber band is sleeved outside the support rods.

[0021] In an alternative embodiment, the mounting plate is connected to at least two horizontally arranged cylinders, and the telescopic directions of every two cylinders are staggered; fixed plates are arranged at both ends of each cylinder along the telescopic direction, and at least two struts are arranged at intervals at the bottom end of each fixed plate.

[0022] In the above implementation process, at least two cylinders arranged staggeredly are provided at the mounting plate, and at least two struts are provided at both opposite ends of each cylinder. The multiple struts are arranged at intervals in the circumferential direction. The distance between the circumferentially arranged struts can be adjusted by the telescoping of the cylinders, so as to realize the outward expansion or inward contraction of the multiple struts, facilitating the grasping or conversion of rubber bands. At least two struts are provided at both opposite ends of each cylinder. When grasping the rubber band, the probability of the struts extending into the rubber band can be increased, improving the grasping efficiency.

[0023] In an alternative embodiment, the first moving member includes a Z-direction linear moving member that moves vertically, and an X-direction linear moving member and a Y-direction linear moving member that move horizontally; the X-direction linear moving member is arranged on the frame, the Y-direction linear moving member is arranged on the X-direction linear moving member, the Z-direction linear moving member is arranged on the Y-direction linear moving member, and the mounting plate of the first gripper is arranged on the Z-direction linear moving member.

[0024] In the above implementation process, by arranging the X-direction linear moving member on the frame, the Y-direction linear moving member on the X-direction linear moving member, the Z-direction linear moving member on the Y-direction linear moving member, and the mounting plate of the first gripper on the Z-direction linear moving member, the spatial position of the first gripper can be adjusted by the movement of the first moving member, facilitating the use of the first gripper to grasp rubber bands at different spatial positions above the vibrating screening plate.

[0038] Please refer to Figure 1 and Figure 2 , embodiments of the present application provide a rubber band sleeving device 1, which includes a frame 10, a feeding mechanism 20 and a rubber band sleeving mechanism 30.

[0039] Among them, please refer to Figure 2 and Figure 3 , the feeding mechanism 20 includes a first vibrating feeding box 21 and a vibrating screening plate 22 arranged on the frame 10. The first discharge port 211 of the first vibrating feeding box 21 is located above the vibrating screening plate 22. The first vibrating feeding box 21 is provided with a first baffle 212. There is a first gap between the bottom end of the first baffle 212 and the bottom plate of the first vibrating feeding box 21 to form the first discharge port 211.

[0040] The first vibrating feeding box 21 vibrates to make the rubber bands in the first vibrating feeding box 21 pass through the first discharge port 211 and fall into the vibrating screening plate 22. The vibrating screening plate 22 vibrates to make the rubber bands move irregularly, forming scattered single rubber bands.

[0041] The rubber band sleeving mechanism 30 can selectively grab a single rubber band and sleeve it outside the workpiece.

[0042] The following further describes the frame 10, the feeding mechanism 20 and the rubber band sleeving mechanism 30 in the rubber band sleeving device 1 provided by the embodiments of the present application with reference to the drawings.

[0043] The frame 10 is used to carry the feeding mechanism 20 and the rubber band sleeving mechanism 30. Exemplarily, the frame 10 can be provided with a machine table, and an installation plate and an installation seat for installing the feeding mechanism 20 and the rubber band sleeving mechanism 30 are arranged on the machine table.

[0044] Furthermore, a door panel can be arranged around the machine table to enclose the feeding mechanism 20 and the rubber band sleeving mechanism 30 within the door panel to protect the feeding mechanism 20 and the rubber band sleeving mechanism 30.

[0045] The feeding mechanism 20 is used to store rubber bands and continuously convey the rubber bands to the rubber band sleeving mechanism 30, so that the rubber band sleeving mechanism 30 can grab a single rubber band and sleeve it outside the workpiece.

[0046] The feeding mechanism 20 provided by the example of this application includes a first vibrating feeding box 21 and a vibrating screening plate 22. The first vibrating feeding box 21 can store rubber bands and convey the rubber bands to the first discharge port 211 of the first vibrating feeding box 21 through vibration, so that the rubber bands can fall onto the vibrating screening plate 22. The first discharge port 211 is formed by the gap between the first baffle 212 and the bottom plate of the box, and a small amount of rubber bands can pass through the first discharge port 211, so that the rubber bands in the vibrating screening plate can be relatively dispersed, so that the vibrating screening plate 22 can vibrate and screen out more single rubber bands in a dispersed state.

[0047] Exemplarily, the first vibrating feeding box 21 includes a bottom plate of the box and a plurality of side plates surrounding the circumferential direction of the bottom plate of the box. One of the side plates is the first baffle 212, and a gap is formed between the bottom end of the first baffle 212 and the bottom plate of the box. The upper part of the first vibrating feeding box 21 is open to facilitate adding rubber bands into the first vibrating feeding box 21.

[0048] Furthermore, in some possible embodiments, the vibration mode of the first vibrating feeding box 21 can be vertical vibration and horizontal vibration.

[0049] The vertical vibration and horizontal vibration modes can refer to the existing multi-axis vibrating table. Exemplarily, two horizontal slide rails can be arranged on the machine table, and sliders are arranged on the slide rails. Two cam structures are arranged on the sliders, and the first vibrating feeding box 21 is arranged on the sliders. During the working process, the first vibrating feeding box 21 can be driven to swing horizontally by the reciprocating movement of the slider along the slider. At the same time, the rotation of the two cam structures can intermittently lift the first vibrating feeding box 21, so that the first vibrating feeding box 21 can vibrate up and down.

[0050] Furthermore, in a possible embodiment, the bottom plate of the first vibrating feeding box 21 can be inclined towards the first discharge port 211. That is, the end of the bottom plate located at the first discharge port 211 is the lower end.

[0051] Furthermore, in a possible embodiment, please continue to refer to Figure 3 a conveyor belt 23 can be arranged outside the first discharge port 211 of the first vibrating feeding box 21. One end of the conveyor belt 23 is connected to the first discharge port 211 of the first vibrating feeding box 21, and the other end of the conveyor belt 23 is located above the vibrating screening plate 22. The conveyor belt 23 is used to convey the rubber bands passing through the first discharge port 211 to above the vibrating screening plate 22 so that the rubber bands fall into the vibrating screening plate 22.

[0052] Furthermore, in some possible embodiments, please continue to refer to Figure 3, the feeding mechanism 20 may also be provided with a second vibrating feeding box 24. The second discharge port 241 of the second vibrating feeding box 24 is located above the first vibrating feeding box 21. The second vibrating feeding box 24 is provided with a second baffle 242. There is a second gap between the bottom end of the second baffle 242 and the bottom plate of the second vibrating feeding box 24 to form the second discharge port 241. The second vibrating feeding box 24 vibrates so that the rubber bands in the second vibrating feeding box 24 pass through the second discharge port 241 and fall into the first vibrating feeding box 21.

[0053] Further, in some possible embodiments, the bottom plate of the second vibrating feeding box 24 is inclined in the direction of the second discharge port 241, and the second vibrating feeding box 24 can vibrate vertically and horizontally.

[0054] The vibrating screening plate 22 can vibrate to make the rubber bands move irregularly. The rubber bands are elastic and will separate from each other during vibration, forming single rubber bands separated from each other, so as to facilitate the rubber band sleeving mechanism 30 to grab the single rubber bands.

[0055] The rubber band sleeving mechanism 30 is used to grab the single rubber bands at the vibrating screening plate 22 and sleave the grabbed rubber bands outside the workpiece.

[0056] Further, in some possible embodiments, the rubber band sleeving mechanism 30 includes a grabbing component 31 and a rubber band sleeving component 32. The grabbing component 31 is used to grab the single rubber bands screened out by the vibrating screening plate 22 of the vibrating screening plate 22. The rubber band sleeving component 32 is used to sleave the rubber bands grabbed by the grabbing component 31 outside the workpiece.

[0057] In order to facilitate grabbing the single rubber bands screened out by the vibrating screening plate 22 of the vibrating screening plate 22, in one possible embodiment, please refer to Figure 2 and Figure 4 , the grabbing component 31 includes an identification camera 311, a processor 312, a first moving member 313 and a first gripper 314. The first moving member 313 is arranged on the frame 10 and is located above the vibrating screening plate 22; the identification camera 311 is arranged on the frame 10 above the vibrating screening plate 22 and the first moving member 313, and is used to identify the position and shape of the target rubber band at the vibrating screening plate 22, send a signal to the first moving member 313 through the processor 312, and the first moving member 313 receives the signal and drives the first gripper 314 to the target position to grab the target rubber band.

[0058] Further, please continue to refer to Figure 4The first moving member 313 includes a Z-direction linear moving member 3131 that moves vertically, and an X-direction linear moving member 3132 and a Y-direction linear moving member 3133 that move horizontally. The X-direction linear moving member 3132 is disposed on the frame 10, the Y-direction linear moving member 3133 is disposed on the X-direction linear moving member 3132, the Z-direction linear moving member 3131 is disposed on the Y-direction linear moving member 3133, and the first gripper 314 is disposed on the Z-direction linear moving member 3131.

[0059] Exemplarily, two X-direction linear moving members 3132 are provided above the frame 10 corresponding to the vibrating screening disk 22 , and both ends of the Y-direction linear moving member 3133 are connected to the two X-direction linear moving members 3132 , respectively.

[0060] Exemplarily, the X-direction linear moving member 3132 may include a first guide rail and a first slider slidably connected to the first guide rail, and the Y-direction linear moving member 3133 is disposed on the first slider. The Y-direction linear moving member 3133 includes a second guide rail and a second slider slidably connected to the second guide rail. The sliding of the first slider and the second slider is driven by a motor. The Z-direction linear moving member 3131 is a telescopic cylinder fixed to the second slider.

[0061] Furthermore, the first gripper 314 can extend into the interior of the target rubber band under the drive of the first movable member 313, and then the first gripper 314 can expand outward to stretch the target rubber band so that the target rubber band is sleeved outside the first gripper 314 to grasp the target rubber band.

[0062] For example, see Figure 5 The first gripper 314 includes a mounting plate 331 and a plurality of support rods 332. One end of the plurality of support rods 332 can be slidably connected to the mounting plate 331 in a direction away from each other, and the other end of the support rod 332 is used to extend into the rubber band.

[0063] When it is necessary to grab a rubber band, the processor 312 analyzes the shape and position of the rubber band obtained by the recognition camera 311, and sends the position signal of the horizontally unfolded single target rubber band to the first moving member 313. The first moving member 313 drives the first gripper to move along the X direction, the Y direction and the Z direction, and inserts at least two support rods 332 into the target rubber band. Then, the multiple support rods 332 slide in a direction away from each other, and the target rubber band is stretched out, so that the target rubber band is set outside the support rods 332.

[0064] Further, in order to facilitate the control of the sliding of the plurality of support rods 332, in a possible embodiment, please continue to refer to Figure 5, at the mounting plate 331, at least two horizontally arranged cylinders 333 are connected, and the telescopic directions of every two cylinders 333 are staggered; at both ends of each cylinder 333 along the telescopic direction, fixing plates 334 are arranged, and at least two support rods 332 are arranged at intervals at the bottom end of each fixing plate 334.

[0065] At least two support rods 332 are arranged on the cylinder 333 through the fixing plate 334. Multiple support rods 332 can increase the probability of the first gripper 314 reaching into the inside of the rubber band, and the fixing plate 334 can increase the strength of the first gripper 314.

[0066] Further, please continue to refer to Figure 4 , the grasping assembly 31 can also be provided with a caching gripper 315. The caching gripper 315 is arranged outside the vibrating screening tray 22. The first moving member 313 can selectively drive the first gripper 314 to sleave the opened target rubber band outside the caching gripper 315 for caching, so that the rubber band sleaving assembly 32 can grasp the target rubber band at the caching gripper 315.

[0067] Exemplarily, the structure of the caching gripper 315 is basically the same as that of the first gripper 314. The support rods 332 in the caching gripper 315 are arranged above the mounting plate 331, and the support rods 332 in the first gripper 314 are arranged below the mounting plate 331. When it is necessary to sleave the rubber band grasped by the first gripper 314 on the caching gripper 315 for caching, the first moving member 313 can be used to drive the first gripper 314 to move above the caching gripper 315, and then continue to drive the first gripper 314 to descend, so that multiple support rods 332 of the caching gripper 315 extend into multiple support rods 332 of the first gripper 314. Then, the cylinders 333 of the first gripper 314 drive multiple support rods 332 to move in the direction of approaching each other to sleave the rubber band outside the support rods 332 of the caching gripper 315, or the cylinders 333 of the caching gripper 315 drive the corresponding support rods 332 to move in the direction of moving away from each other to sleave the rubber band outside the support rods 332 of the caching gripper. Then, the first moving member 313 drives the first gripper 314 to move upward, so that the support rods 332 of the first gripper 314 withdraw outside the caching gripper 315.

[0068] Further, since the caching gripper 315 does not need to randomly grasp rubber bands in different unfolded forms, therefore, in some possible embodiments, only four support rods 332 can be arranged at the caching gripper 315, and the width of the four support rods 332 can be appropriately increased to improve the strength of the caching gripper 315.

[0069] Further, please refer to Figure 6 , the rubber band sleaving assembly 32 can be provided with a robotic arm 321 and a second gripper 322.

[0070] The robot arm 321 can drive the second gripper 322 to move to the top of the cache gripper 315 to grab the rubber band, and can also drive the second gripper 322 to move to the workpiece so that the rubber band grabbed by the second gripper 322 is aligned with the workpiece.

[0071] The structure of the second gripper 322 may be consistent with that of the first gripper 314 and the cache gripper 315 , both of which include a mounting plate 331 , a support rod 332 and a cylinder 333 .

[0072] Further, in order to facilitate the second gripper 322 to put the gripped rubber band on the workpiece, in a possible embodiment, please continue to refer to Figure 6 The second gripper 322 further includes a second moving member 335 disposed on the mounting plate 331, and a push plate 336 disposed on the second moving member 335; the push plate 336 is provided with a plurality of strip-shaped notches 337, and the support rod 332 of the second gripper 322 can pass through the corresponding notches 337 when expanding outward to open the rubber band. When the mechanical arm 321 drives the second gripper 322 to move, so that the workpiece is inserted into the rubber band, the second moving member 335 can selectively push the push plate 336 in a direction away from the mounting plate 331, and push the rubber band sleeved on the support rod 332 out of the support rod 332, so that the rubber band is sleeved on the workpiece.

[0073] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
