[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0019] like Figure 1-11As shown, the present invention provides an automatic collection device for waste bearings, comprising a support platform 1, on which a dividing plate device 2 is fixedly installed, on which a dividing plate device 2 is provided, three collecting cylinders 3 penetrating the dividing plate are equidistantly distributed along the circumferential direction, the three collecting cylinders 3 are all used to collect waste bearings, and are respectively the first station, the second station and the third station in the counterclockwise direction, and a stepped hole 4 is penetrated through the top of the collecting cylinder 3, a bending opening 5 connected to the stepped hole 4 is provided on the outer wall of the collecting cylinder 3, a lifting opening 6 connected to the stepped hole 4 is provided at the bottom of the collecting cylinder 3, and a vibration plate body 7 for conveying waste bearings is provided on one side of the support platform 1, and a shifting and unloading mechanism 8 is provided at the output port of the vibration plate body 7, and the shifting and unloading mechanism 8 is used to convey the waste bearings in the vibration plate body 7 to the collecting cylinder 3 at the first station, and A wire conveying mechanism 9 for conveying cut wire and a mechanical arm 10 for clamping the cut wire and grouped waste bearings are fixedly installed on the top of the support platform 1. A clamping claw is installed at the front end of the mechanical arm 10, and the cut wire is clamped by the clamping claw. An upper bending mechanism 11 and a lower bending mechanism 12 are arranged on the support platform 1. The upper bending mechanism 11 and the lower bending mechanism 12 correspond to each other up and down and are located at the top and bottom of the collecting cylinder 3 at the second station. The upper bending mechanism 11 and the lower bending mechanism 12 are used to bend the top and bottom ends of the wire placed in the collecting cylinder 3, and a lifting mechanism 13 is fixedly installed on the support platform 1. The lifting mechanism 13 is arranged below the collecting cylinder 3 at the third station, and is used to lift the grouped waste bearings inside the collecting cylinder 3 at the third station. A turnover box 14 for placing grouped waste bearings is arranged on one side of the dividing plate device 2.

[0020] Specifically, the shifting and unloading mechanism 8 can stop briefly after pushing a certain number of waste bearings. During this period, the dividing plate device 2 can control the rotation of the dividing plate so that the collecting cylinder 3 after being full can rotate, and the empty collecting cylinder 3 is moved to the bottom of the shifting and unloading mechanism 8 for loading. The control system of this method is a well-known public technology, which is already a technology that can be familiar to and implemented by technical personnel in this field. Because this scheme only protects the physical structure and does not involve the protection of circuits and systems, the circuits and systems are not elaborated in detail. It should be emphasized that the description of the circuits and systems is only for the purpose of supplementing the feasibility and authenticity of this scheme.

[0021] Combination Figure 3 and Figure 6As shown, in this embodiment, the shifting unloading mechanism 8 includes a support frame 81, a conveying device 82 and a mounting frame 83 installed on the support frame 81, a rodless cylinder 84 installed on the mounting frame 83, a pushing frame 85 connected to the rodless cylinder 84, and a material guide 86 installed on the mounting frame 83, a guide hole 87 is opened through the material guide 86, and the guide hole 87 corresponds to the stepped hole 4 of the collecting barrel 3 at the first station, and the pushing frame 85 is arranged at one end of the conveying device 82, and is used to push the waste bearing on the conveying device 82 to the top of the guide hole 87.

[0022] Specifically, the top of the pusher rack 85 is an L-shaped plate, and a circular groove for fitting the bearing is opened on the outer side of the corner of the L-shaped plate, so that when the rodless cylinder 84 drives the pusher rack 85 to move, the pusher rack 85 can push the bearing in the circular groove onto the guide member 86, and make the waste bearing fall from the top of the guide hole 87 into the collecting cylinder 3. When the rodless cylinder 84 drives the pusher rack 85 to move, its speed is relatively fast, and the pusher rack 85 can realize rapid reciprocating work, thereby facilitating the waste bearing to enter the guide hole 87, and there will be no slow movement, which will cause the bearing to tilt and fall at the guide hole 87. At the same time, a rib is also provided at the circular groove to further prevent the bearing from tilting at the guide hole 87.

[0023] More specifically, when the pushing rack 85 pushes the used bearing to move, it has a longer side for blocking the bearing on the conveying device 82 to prevent the bearing from falling, and the bottom surface of the guide member 86 is spaced a distance from the top surface of the collecting cylinder 3 to prevent the collecting cylinder 3 from colliding with the shifting unloading mechanism 8 when rotating.

[0024] Combination Figure 4 and Figure 8 As shown, in this embodiment, the upper bending mechanism 11 includes a hanger 110 installed on the support platform 1, a first cylinder 111 installed on the hanger 110, a first sliding seat 112 connected to the output end of the first cylinder 111, a first micro-cylinder 113 movably installed on the first sliding seat 112, an upper pressure seat 114 fixedly installed on the first sliding seat 112, and an upper bending plate 115 hinged on the upper pressure seat 114, the bottom of the upper pressure seat 114 and the upper bending plate 115 and one side of the upper bending plate 115 are respectively provided with upper bending grooves 15 for bending iron wires, and the output end of the first micro-cylinder 113 is movably connected to the upper bending plate 115.

[0025] Specifically, the bottom height of the hanger 110 is higher than the top height of the collecting cylinder 3, so when the dividing plate device 2 drives the collecting cylinder 3 to rotate, there will be no problem of collision between the collecting cylinder 3 and the upper bending mechanism 11, and a transverse guide rail is also installed on the hanger 110, and the first sliding seat 112 is slidably connected to the transverse guide rail to ensure the stability of the first sliding seat 112, and further ensure the stability of the upper pressure seat 114 and the upper bending plate 115, which is beneficial for the upper bending mechanism 11 to bend the iron wire.

[0026] Preferably, an upper notch 16 is opened on the top side of the collecting tube 3 , and the upper notch 16 corresponds to the bending opening 5 and the upper bending plate 115 , respectively, and the interior of the upper notch 16 is adapted to the bottom end of the upper pressure seat 114 and the exterior of the upper bending plate 115 .

[0027] Specifically, the inner spacing value of the upper slot 16 is equal to the inner spacing value of the bending mouth 5, and when a certain amount of waste bearings are collected and placed, the top surface of the bearing at the top end is lower than the inner bottom surface of the upper slot 16, and is almost close to the inner bottom surface of the upper slot 16. Therefore, when the first cylinder 111 pushes the first sliding seat 112 forward, the upper bending plate 115 and the upper pressure seat 114 move to the top of the topmost bearing, and the spacing distance is greater than and close to the diameter of the iron wire, which is conducive to comprehensive bending of the iron wire and ensures the stability of the bearing group after the iron wire is bent.

[0028] Combination Figure 5 and Fig. 9 As shown, in the present embodiment, the lower bending mechanism 12 includes an elevated plate 120 installed on the top of the support platform 1, a second cylinder 121 installed on the elevated plate 120, a second sliding seat 122 connected to the output end of the second cylinder 121, a second micro-cylinder 123 movably installed on the second sliding seat 122, a lower pressure seat 124 fixedly installed on the second sliding seat 122, and a lower bending plate 125 hinged on the lower pressure seat 124, the top of the lower pressure seat 124 and the lower bending plate 125 and one side of the lower bending plate 125 are respectively provided with a lower bending groove 17 for bending the iron wire, and the output end of the second micro-cylinder 123 is movably connected to the lower bending plate 125.

[0029] Specifically, the top surface of the lower pressure seat 124 and the top surface of the lower bending plate 125 are spaced a certain distance from the inner bottom wall of the lifting port 6, and the distance is greater than and close to the diameter of the iron wire, which is conducive to the comprehensive bending of the iron wire when the lower pressure seat 124 and the lower bending plate 125 move, thereby ensuring the stability of the bearing group after the iron wire is bent.

[0030] Preferably, a lower slot 18 is opened on the bottom end side of the collecting cylinder 3, and the lower slot 18 corresponds to the bending mouth 5 and the lower bending plate 125 respectively, and the interior of the lower slot 18 is adapted to the top of the lower pressure seat 124 and the exterior of the lower bending plate 125, and the inner spacing value of the lower slot 18 is equal to the inner spacing value of the bending mouth 5.

[0031] Further, combined with Fig. 9 As shown, a wire guide bucket 19 is fixedly installed on the second sliding seat 122, and the inner bottom of the wire guide bucket 19 is a U-shaped groove, and the diameter value of one end of the U-shaped groove is equal to the diameter of the wire, and the wire guide bucket 19 is located directly below one end of the lower bending plate 125, and the center of one end of the U-shaped groove is on the same vertical line as the center of the lower bending groove 17 on one side of the lower bending plate 125.

[0032] Specifically, when the iron wire is placed on multiple bearing inner rings inside the collecting tube 3 through the robotic arm 10, one end of the iron wire can be accurately guided in the U-shaped groove of the wire guide bucket 19 due to the side bucket design at the top end of the wire guide bucket 19, and when the iron wire is completely fitted into the inner end arc in the U-shaped groove, the iron wire can be correspondingly arranged in the lower bending groove 17 of the vertical section of the lower bending plate 125, which is beneficial for the lower bending plate 125 to bend the iron wire when the second sliding seat 122 moves.

[0033] Combination Figure 7 and Fig.10 As shown, in this embodiment, the lifting mechanism 13 includes a third cylinder 130 installed on the support platform 1, a lifting plate 131 connected to the output end of the third cylinder 130, and a lifting support rod 132 installed on the lifting plate 131. The lifting support rod 132 corresponds to the lifting port 6 and is adapted to the inside of the lifting port 6.

[0034] Specifically, two lifting rods 132 are provided, and two corresponding lifting ports 6 are also provided. The two lifting ports 6 are symmetrically arranged with the bending port 5 as the symmetry axis. Therefore, when the lifting rod 132 enters the lifting port 6, the lifting rod 132 can push the grouped bearings up through the pushing work of the third cylinder 130, so as to ensure the stability and smoothness of the bearings when they rise. After the grouped bearings rise and emerge from the top of the collecting tube 3, the robot arm 10 can grab the grouped bearings, and then lift the grouped bearings, so that after the grouped bearings leave the inner cavity of the collecting tube 3, they can be placed in the turnover box 14 in sequence with the help of the work of the robot arm 10, so as to facilitate the manual centralized recovery and processing of the bearings in the turnover box 14 in the later stage.

[0035] Combination Figure 2As shown, in this embodiment, the wire conveying mechanism 9 includes a support 91 connected to the support platform 1, a group of stepper motors 92 installed on the support 91, a gear disc group 93 and a guide plate 94, and a chain 95 meshingly connected to the corresponding gear disc group 93, and a plurality of T-plates 96 for pushing the wire to move are respectively connected to the surfaces of the two chains 95 close to each other, the output end of the stepper motor 92 is connected to a gear disc in the gear disc group 93, and a group of guide plates 94 are located between the two chains 95, and the top surface of the guide plate 94 is higher than the top surface of the chain 95 when it rotates.

[0036] Preferably, two material guide plates 94 in one group are respectively provided with corresponding material stopping areas at one end, and the inner bottom of the material stopping area is inclined.

[0037] Specifically, the iron wire cut by the wire cutting machine can be transferred to the top of the guide plate 94 in turn, and at the same time be located between every two T-plates 96, and then when the toothed disc group 93 drives the chain 95 to rotate, the T-plate 96 can push the iron wire on the guide plate 94 forward, causing the iron wire to fall into the stopping area at the front section of the guide plate 94 in turn, and the iron wire in the stopping area is convenient for the gripper at the front end of the robot arm 10 to grasp.

[0038] Furthermore, the cut wire can be transported and placed manually on the guide plate 94, or it can be placed by other mechanical equipment. This article only protects the wires as they are transported one by one into the material stopping area, and the source of the wires is not protected, so it will not be elaborated on. The cutting, transportation and placement of wires are all well-known public technologies, and the simplest and most cost-effective way to place them is manual placement. This solution can be operated manually when there are too many questions about the source of the wires. The wire conveying mechanism 9 in this solution can also be removed during actual use, and a wire placement box is used to place the wires, and the robot arm 10 clamps the wires in the placement box, and then multiple wires can be placed in the box manually, and the robot arm 10 can continue to clamp them. When the clamping is about to be completed, the wire can be manually replenished.

[0039] Furthermore, when the wire conveying mechanism 9 is in use, the stepper motor 92 is controlled by an external controller, so that after the robot arm 10 clamps each wire, the stepper motor 92 rotates and causes the subsequent wire to enter the material stopping area, and this solution only protects the physical structure and does not involve the protection of the circuit and system. It should be emphasized here that the description of the circuit and system is only for the purpose of supplementing the feasibility and authenticity of this solution, and the circuit and system technology is a well-known public technology that can be programmed and implemented by those skilled in the art.

[0040] The working principle and use process of the present invention: When the waste bearings are loaded into the collecting barrel 3: a large number of waste bearings after disassembly and inspection are manually put into the vibration plate body 7, and the vibration plate body 7 can discharge the waste bearings one by one after working, so that the discharged bearings are moved to the conveying device 82, and the bearings are conveyed to the pusher rack 85 by the conveying device 82, so that the rodless cylinder 84 drives the pusher rack 85 to push the bearing to the guide member 86, and the bearing can fall through the guide hole 87 and fall into the collecting barrel 3, completing the collection of multiple waste bearings; When multiple waste bearings are tightened at both ends: after the bearings in the collecting cylinder 3 on the first station fall a certain amount, the indexing plate device 2 can drive the collecting cylinder 3 to rotate, so that the fully collected collecting cylinder 3 rotates to the second station and is located at the upper bending mechanism 11 and the lower bending mechanism 12. After the indexing plate device 2 stops rotating, the robot arm 10 clamps the iron wire, and the second cylinder 121 pushes the second sliding seat 122 to move, so that after the second sliding seat 122 moves, the wire guide bucket 19 can correspond to the center of the collecting cylinder 3, and then the robot arm 10 sends the iron wire from the top of the collecting cylinder 3 to the bottom, so that the bottom end of the iron wire stays in the wire guide bucket 19, and then the second cylinder 121 drives the second sliding seat 122 to reset, so that the lower bending plate 125 and the lower pressure seat 124 can move to bend the iron wire staying in the lower bending groove 17 by 90 degrees, and then after the second cylinder 121 stops working, the second micro air The cylinder 123 can push the lower bending plate 125 to move upward, so that the lower bending plate 125 bends one end of the wire by 90 degrees again, and after the lower bending plate 125 completely enters the bending opening 5, the wire is bent in the bending opening 5 and fits tightly against the outer wall of the bearing. After the mechanical arm 10 releases the wire, the upper bending mechanism 11 works, and the first cylinder 111 pushes the first sliding seat 112 to move forward, so that the upper bending plate 115 and the upper pressing seat 114 bend the top of the wire by 90 degrees. After the first sliding seat 112 moves to a certain position, the first micro-cylinder 113 works to push the upper bending plate 115 to rotate downward, so that the upper bending plate 115 bends the wire by 90 degrees when entering the bending opening 5, so that the upper and lower ends of the wire are both in the bending opening 5 after bending, and fit tightly against the bearing, thereby ensuring the fastening of the two ends of the bearing in the collecting tube 3 to avoid the problem of the bearing falling off after collection. When taking out the tightened group of bearings: when the bearings inside the collecting cylinder 3 at the first station are full again, the dividing plate device 2 can drive the collecting cylinder 3 to rotate, so that the tightened group of bearings can be rotated to the third station, and when the third cylinder 130 works to push the lifting plate 131 up, the lifting support rod 132 can lift the group of bearings in the collecting cylinder 3, so that the bearings move upward and are exposed, and then the robot arm 10 can clamp and lift the group of bearings, and place the group of bearings in the turnover box 14, which is conducive to the subsequent manual unified recycling of multiple group of bearings.

[0041] In summary, the present solution does not require manual labor to pass through multiple waste bearings one by one with wire. Instead, the waste bearings only need to be manually placed in the vibration plate body 7, and the shifting unloading mechanism 8 is used to collect the waste bearings in the collecting tube 3. After the collecting tube 3 is full, the mechanical arm 10 is used to clamp the wire and pass it through multiple bearing inner rings. Subsequently, the bottom and top ends of the wire are bent in turn with the help of the lower bending mechanism 12 and the upper bending mechanism 11, so that both ends of the bearings are tightened. Finally, the lifting mechanism 13 is used to cooperate with the work of the mechanical arm 10, so that the grouped bearings collected in a standardized manner can be placed in the turnover box 14, which is convenient for subsequent centralized and unified processing by manual labor. This is different from manual standardized collection and processing, saves time and effort, and can ensure collection efficiency for a large number of waste bearings.
