Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing, and in particular, to a sheet metal turning device. Background Art

[0002] Currently, sheet-like materials are common processing materials. During the production and processing on the assembly line, it is usually necessary to perform processing operations such as cutting or flanging on the four sides of the sheet metal. At this time, it is necessary to turn the sheet metal so as to process the four sides of the sheet metal separately.

[0003] During the turning process of the sheet metal, a common turning device is a manipulator with a suction cup. The manipulator makes the suction cup adsorb the sheet metal by lifting, and then drives the sheet metal to turn to a corresponding angle through a turning cylinder, so as to facilitate the subsequent processing of the sheet metal.

[0004] Regarding the above related technology: The manipulator drives the sheet metal to rotate, resulting in a large space required for the rotation of the sheet metal, and thus a large occupied area of the turning device. Summary of the Invention

[0005] In order to reduce the occupied area of the turning device, this application provides a sheet metal turning device.

[0006] The sheet metal turning device provided by this application adopts the following technical solutions:

[0007] A sheet metal turning device, comprising:

[0008] A frame, which is installed on the ground;

[0009] A conveying mechanism, the conveying mechanism includes a driving component and two conveyor belts. The driving component is installed on the frame, and the two conveyor belts are respectively connected to the driving component. The two conveyor belts are arranged on the frame at intervals;

[0010] An inclined lifting mechanism, which is arranged on the frame. The inclined lifting mechanism is located at the middle position between the two conveyor belts, and the inclined lifting mechanism is arranged close to the upper conveying surface of the conveyor belt. The inclined lifting mechanism is used to drive the sheet metal to move away from the conveyor belt and drive the sheet metal to incline;

[0011] A turning cylinder, which is installed on the frame. The turning cylinder is connected to the inclined lifting mechanism, and the turning cylinder is used to drive the inclined lifting mechanism to turn.

[0012] By adopting the above technical solution, when the sheet material is placed on the two conveyor belts, the conveyor belts can drive the sheet material above the inclined lifting mechanism. At this time, the inclined lifting mechanism can first drive the sheet material above the conveyor belts, then drive the sheet material to tilt, and then the steering cylinder drives the sheet material to turn to a specified angle through the inclined lifting mechanism, thereby completing the turning of the sheet material, and further achieving the purpose of reducing the occupied area of the turning device.

[0013] Optionally, a turntable is arranged between the inclined lifting mechanism and the steering cylinder. The inclined lifting mechanism includes a connecting plate, an air pump and a pneumatic component. The connecting plate is arranged close to the upper conveying surface of the conveyor belt. The pneumatic component is movably connected to the connecting plate. At least two pneumatic components are provided. One pneumatic component is connected to the central position of the connecting plate, and the other pneumatic component is connected to the edge angle of the connecting plate. The stroke of the pneumatic component close to the central position of the connecting plate among the two pneumatic components is shorter than that of the other pneumatic component. The two pneumatic components are respectively connected to the turntable, and the air pump is communicated with the pneumatic component.

[0014] By adopting the above technical solution, the connecting plate is used to carry the sheet material. The air pump can inflate the pneumatic component, and the two pneumatic components are communicated with each other, so that the two pneumatic components can jointly push the connecting plate to move away from the conveyor belt. And the stroke of the pneumatic component close to the central position of the connecting plate among the two pneumatic components is shorter than that of the other pneumatic component, so that after the pneumatic component close to the central position of the connecting plate stops moving, the other pneumatic component can continue to move, which is beneficial to making the connecting plate in an inclined state and achieving the purpose of reducing the occupied area of the turning device to a certain extent.

[0015] Optionally, the pneumatic component includes a connecting piece and a sealing sleeve. One end of the sealing sleeve is installed on the turntable. The end of the sealing sleeve close to the turntable is communicated with the air pump. The other end of the sealing sleeve is closed. A sliding hole is formed through the closed end of the sealing sleeve. The connecting piece includes a push rod and a sliding block. The sliding block is slidably arranged in the sealing sleeve. One end of the push rod passes through the sliding hole and inserts into the sealing sleeve. The end of the push rod inserted into the sealing sleeve is connected to the sliding block. The other end of the push rod is movably connected to the connecting plate.

[0016] By adopting the above technical solution, the mutual cooperation of the sealing sleeve, the push rod and the sliding block enables the gas conveyed by the air pump into the sealing sleeve to push the sliding block to move away from the turntable, and the sliding block can drive the push rod to move, which is beneficial to the pneumatic component to drive the connecting plate to move.

[0017] Optionally, an elastic member is disposed inside the sealing sleeve. One end of the elastic member is disposed on the sealing sleeve, and the other end of the elastic member is connected to the push rod.

[0018] By adopting the above technical solution, the elastic member can drive the slider to move in the sealing sleeve towards the bogie, so as to facilitate driving the push rod back to the initial position by the elastic member. Furthermore, it is beneficial to move the sheet material onto the conveyor belt after the sheet material turning is completed, facilitating the conveyor belt to drive the sheet material to move.

[0019] Optionally, a plurality of connecting holes are formed through the connecting plate. The plurality of connecting holes are distributed in a rectangular array on the connecting plate. A suction cup is slidably inserted into each connecting hole. One end of the suction cup passes through the connecting hole. A limiting block is connected to the end of the suction cup passing through the connecting hole. One side of the limiting block close to the suction cup is attached to one side of the connecting plate close to the pneumatic component.

[0020] By adopting the above technical solution, a plurality of suction cups are arranged on the connecting plate, such that when the sheet material is located above the connecting plate and the pneumatic component drives the connecting plate to move towards the sheet material, the suction cups can adsorb on the sheet material, thereby facilitating connecting and fixing the sheet material to the connecting plate. Furthermore, it is beneficial to drive the sheet material to move respectively through the two pneumatic components via the connecting plate.

[0021] Optionally, a plurality of extrusion blocks are arranged on one side of the connecting plate close to the pneumatic component. Every two extrusion blocks are arranged close to one suction cup, and the two extrusion blocks are symmetrically distributed along the axis of the suction cup. One end of each of the two extrusion blocks is attached to the suction cup. A through hole is formed through the end of the suction cup inserted into the connecting hole along its own length direction. One end of the through hole close to the limiting block penetrates through the limiting block. The axis of the through hole coincides with the axis of the connecting hole.

[0022] By adopting the above technical solution, when the suction cup adsorbs on the sheet material, the sheet material applies pressure to the suction cup, causing the suction cup to move towards the connecting plate. At this time, the two extrusion blocks jointly squeeze one end of the suction cup passing through the connecting hole, closing the through hole, thereby facilitating the suction cup to adsorb the sheet material and enabling the sheet material to be stably connected to the connecting plate. When the sheet material turning is completed and the sheet material abuts against the conveyor belt, the connecting plate drives the suction cup to move away from the sheet material. There is still suction force between the suction cup and the sheet material, making it difficult for the suction cup to move away from the sheet material. At this time, the two extrusion blocks no longer squeeze one end of the suction cup passing through the connecting hole, opening the through hole, and the suction cup detaches from the sheet material. Furthermore, it is beneficial to detach the sheet material from the connecting plate.

[0023] Optionally, a support frame is provided on the rack, and the support frame is attached to the side of the upper conveying surface of the conveyor belt close to the lower conveying surface. An air flow chamber is formed inside the support frame. Air flow holes are formed on the side of the support frame close to the upper conveying surface of the conveyor belt. Ventilation holes are formed on the conveyor belt. The air flow holes are respectively communicated with the air flow chamber and the ventilation holes. A negative pressure fan is provided on the rack, and the negative pressure fan is communicated with the air flow chamber.

[0024] By adopting the above technical solution, the negative pressure fan can create a negative pressure in the air flow chamber, enabling external air to flow into the air flow chamber successively through the ventilation holes and the air flow holes, which is beneficial to adsorbing the sheet material on the conveyor belt, and then facilitating the conveyor belt to drive the sheet material to move.

[0025] Optionally, a start-stop switch is provided on the connecting plate. The start-stop switch includes a fulcrum, a contact rod and a sensor. The fulcrum and the sensor are respectively provided on the side of the connecting plate close to the pneumatic component. The contact rod is rotatably connected to the fulcrum. One end of the contact rod is connected to the limit block, and the other end of the contact rod abuts against the sensor. The sensor is electrically connected to the negative pressure fan, and the sensor is used to control the start and stop of the negative pressure fan.

[0026] By adopting the above technical solution, when the sheet material is connected to the connecting plate, the suction cup drives the limit block to move towards the bogie. The limit block drives the contact rod to move, causing the end of the contact rod away from the limit block to abut against the sensor. At this time, the negative pressure fan stops working, so that the sheet material is no longer adsorbed on the conveyor belt, facilitating the tilting lifting mechanism to drive the sheet material to move. When the sheet material detaches from the connecting plate, the suction cup drives one end of the contact rod to move away from the bogie through the limit block, so that the end of the contact rod away from the limit block no longer abuts against the sensor. At this time, the negative pressure fan restarts to work, causing the sheet material to be adsorbed on the conveyor belt again, and then facilitating the conveyor belt to drive the sheet material to move.

[0027] Optionally, a counterweight is provided at one end of the contact rod close to the sensor, and the end of the counterweight away from the contact rod abuts against the sensor.

[0028] By adopting the above technical solution, after the sheet material detaches from the connecting plate, the counterweight can drive the contact rod to move away from the sensor, which is beneficial to reducing the possibility that when there is no sheet material connected to the connecting plate, the counterweight abuts against the sensor, causing the negative pressure fan to stop working and making it difficult for the conveyor belt to drive the sheet material to move.

[0029] Optionally, a plurality of rollers are distributed in a rectangular array on the rack. The plurality of rollers are all located between the two conveyor belts, and the plurality of rollers are all arranged close to the upper conveying surface of the conveyor belt. The plurality of rollers can be divided into two groups, and the tilt lifting mechanism is located between the two groups of rollers.

[0030] By adopting the above technical solution, the arrangement of the rollers can support the sheet material, which is beneficial for the two conveyor belts to jointly drive the sheet material to move.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. Through the mutual cooperation of the steering cylinder, the bogie, the connecting plate, the suction cup, the air pump, and the pneumatic components, it is convenient to drive the sheet material above the conveyor belt and make the sheet material inclined, which is beneficial to complete the steering of the sheet material, and further beneficial to achieve the purpose of reducing the occupied area of the steering device;

Through the mutual cooperation of the connecting plate, the extrusion block, and the suction cup, it is convenient to adsorb and connect the sheet material to the connecting plate before the sheet material is turned, and it is beneficial to separate the sheet material from the connecting plate after the sheet material is turned;

[0034] 3. Through the mutual cooperation of the connecting plate, the suction cup, the limiting block, the fulcrum, the touch rod, the sensor, and the configuration block, when the sheet material is connected to the connecting plate, the negative pressure fan can stop working, and when the sheet material is separated from the connecting plate, the negative pressure fan can start working, which is convenient for the tilt lifting mechanism to drive the sheet material to move and tilt, and further beneficial for the steering cylinder to drive the sheet material to turn.

When the support frame 11 is attached to the conveyor belt 22, the air flow holes 112 can communicate with the ventilation holes 221.

[0053] Refer to Figure 1 and Figure 2 , a negative pressure fan 6 is also fixedly installed on the frame 1. The negative pressure fan 6 is communicated with the air flow cavity 111. Thus, when the negative pressure fan 6 works, a negative pressure can be formed in the air flow cavity 111, and then it is convenient to adsorb the sheet material 5 on the conveyor belt 22, and to a certain extent, it is convenient for the conveyor belt 22 to drive the sheet material 5 to move.

[0054] Refer to Figure 1 , a steering cylinder 4 is fixedly installed on the frame 1. The steering cylinder 4 is located in the middle position between the two conveyor belts 22 and below the conveyor belt 22. A steering frame 41 is fixedly connected to the steering cylinder 4 in the direction close to the conveyor belt 22.

[0055] Refer to Figure 1 , an inclined lifting mechanism 3 is fixedly installed on the steering frame 41, so that the steering cylinder 4 can drive the inclined lifting mechanism 3 to turn through the steering frame 41.

[0056] Refer toFigure 1 And Figure 4 There can be various types of tilt lifting mechanisms 3. The tilt lifting mechanism 3 in this embodiment includes a connecting plate 31, an air pump 32, and a pneumatic component 33. Among them, the air pump 32 is fixedly installed on the bogie 41. The connecting plate 31 is arranged close to the upper conveying surface of the conveyor belt 22, and the connecting plate 31 is located at the middle position between the two conveyor belts 22.

[0057] Refer to Figure 4 , There are at least two pneumatic components 33. The two pneumatic components 33 are respectively fixedly installed on the bogie 41. The ends of the two pneumatic components 33 far from the bogie 41 are respectively movably connected to the connecting plate 31, and the two pneumatic components 33 are communicated with each other.

And the stroke of the pneumatic component 33 near the central position of the connecting plate 31 among the two pneumatic components 33 is shorter than the stroke of the other pneumatic component 33.

[0059] Refer to Figure 2 And Figure 4 , There can be various types of pneumatic components 33. The pneumatic component 33 in this embodiment includes a connecting member 331 and a sealing sleeve 332. Among them, one end of the sealing sleeve 332 is fixedly connected to the bogie 41, the other end of the sealing sleeve 332 is closed, and a sliding hole 3321 is formed through the closed end of the sealing sleeve 332, and the axis of the sliding hole 3321 coincides with the axis of the sealing sleeve 332.

[0060] Refer to Figure 4 , The circumferential side wall of the sealing sleeve 332 is communicated with the air pump 32, and the ends of the two sealing sleeves 332 close to the bogie 41 are communicated with each other.

[0061] Refer to Figure 5 , There can be various types of connecting members 331. The connecting member 331 in this embodiment includes a push rod 3311 and a slider 3312. The slider 3312 is slidably arranged in the sealing sleeve 332, and the side wall of the slider 3312 is attached to the inner wall of the sealing sleeve 332.

[0062] Refer to Figure 4 And Figure 5 , One end of the push rod 3311 passes through the sliding hole 3321 and is inserted into the sealing sleeve 332. The end of the push rod 3311 inserted into the sealing sleeve 332 is fixedly connected to the slider 3312, and the end of the push rod 3311 far from the slider 3312 is movably connected to the connecting plate 31.

[0063] Refer to Figure 5, an elastic member 3322 is further disposed inside the sealing sleeve 332. The elastic member 3322 can be configured in various forms. In this embodiment, the elastic member 3322 is a spring. One end of the elastic member 3322 is fixedly connected to the inner wall of the sealing sleeve 332 near one end of the sliding hole 3321, and the other end of the elastic member 3322 is fixedly connected to one side of the slider 3312 near the push rod 3311.

[0064] Referring to Figure 2 , a plurality of connecting holes 311 are formed through the connecting plate 31. The plurality of connecting holes 311 are distributed in a rectangular array on the connecting plate 31. The cross-section of the connecting hole 311 is fan-shaped, and the end with a smaller diameter in the connecting hole 311 is close to the bogie 41.

[0065] Referring to Figure 4 , a suction cup 312 is slidably inserted into each connecting hole 311. The suction cup 312 can be configured in various forms. In this embodiment, the suction cup 312 is an elastic suction cup. One end of the suction cup 312 passes through the connecting hole 311 and extends to the side of the connecting plate 31 close to the bogie 41, and the end of the suction cup 312 inserted into the connecting hole 311 is adapted to the shape of the connecting hole 311.

[0066] Referring to Figure 2 , a plurality of extrusion blocks 313 are fixedly installed on one side of the connecting plate 31 close to the pneumatic assembly 33. Among them, every two extrusion blocks 313 are arranged close to one suction cup 312. The two extrusion blocks 313 are symmetrically distributed along the axis of the suction cup 312, and the two extrusion blocks 313 respectively abut against one end of the suction cup 312 close to the bogie 41.

[0067] Referring to Figure 6 , a limiting block 3121 is fixedly connected to the end of the suction cup 312 passing through the connecting hole 311, and one side of the limiting block 3121 close to the suction cup 312 can be attached to one side of the extrusion block 313 close to the pneumatic assembly 33, thereby facilitating reducing the possibility of the suction cup 312 detaching from the connecting plate 31.

[0068] Referring to Figure 6 , a through hole 3122 is formed through the suction cup 312 along its own length direction. One end of the through hole 3122 close to the limiting block 3121 penetrates through the limiting block 3121, and the axis of the through hole 3122 coincides with the axis of the suction cup 312 itself.

[0069] Referring to Figure 5 and Figure 7 , when the sheet material 5 moves to the connecting plate 31 along with the conveyor belt 22 (referring to Figure 4When above the ( ), the air pump 32 fills the sealing sleeve 332 with gas. The gas can push the slider 3312 to move inside the sealing sleeve 332. The slider 3312 pushes the connecting plate 31 to move through the push rod 3311, so that the suction cup 312 is pressed against the sheet material 5. At this time, the suction cup 312 moves in the direction close to the bogie 41 under the action of the sheet material 5, so that the two pressing blocks 313 can simultaneously press the suction cup 312, thereby closing the through hole 3122 (refer to Figure 6 ), and then enabling the suction cup 312 to adsorb the sheet material 5.

[0070] Refer to Figure 1 and Figure 5 , when the air pump 32 no longer fills the sealing sleeve 332 with gas, the elastic member 3322 can push the slider 3312 to move in the direction close to the bogie 41. The slider 3312 drives the push rod 3311 to move, so that the connecting plate 31 drives the sheet material 5 to move in the direction close to the bogie 41.

[0071] Refer to Figure 1 and Figure 5 , when the sheet material 5 moves with the connecting plate 31 until it abuts against the conveyor belt 22, there is still a suction force between the suction cup 312 and the sheet material 5. When the connecting plate 31 drives the suction cup 312 to move in the direction close to the bogie 41, the suction cup 312 is not easy to move away from the sheet material 5. At this time, the pressing block 313 no longer presses the suction cup 312, thereby opening the through hole 3122 (refer to Figure 6 ), and the suction cup 312 detaches from the sheet material 5, which is beneficial for the sheet material 5 to detach from the connecting plate 31.

[0072] Refer to Figure 1 and Figure 6 , a start-stop switch 7 is arranged on one side of the connecting plate 31 close to the negative pressure fan 6. Among them, at least two start-stop switches 7 are arranged, and the two start-stop switches 7 are symmetrically distributed on the connecting plate 31. The start-stop switch 7 can be arranged in various ways. The start-stop switch 7 in this embodiment includes a fulcrum 71, a contact rod 72 and a sensor 73.

[0073] Refer to Figure 4 and Figure 6 , the fulcrum 71 is fixedly installed on one side of the connecting plate 31 close to the pneumatic component 33, and the fulcrum 71 is arranged close to the limiting block 3121. The middle part of the contact rod 72 is movably connected to the fulcrum 71, so that the contact rod 72 can rotate around the fulcrum 71 and can slide relative to the fulcrum 71.

[0074] Refer to Figure 4 and Figure 6One end of the touch rod 72 is rotatably connected to the adjacent limit block 3121 , and the other end of the touch rod 72 is fixedly connected to a counterweight block 721 , which can drive the touch rod 72 to move in a direction away from the connecting plate 31 .

[0075] Reference Figure 1 and Figure 6 The sensor 73 can be configured in various ways. The sensor 73 in this embodiment is a pressure sensor. The sensor 73 is fixedly mounted on the connecting plate 31, and the sensor 73 is disposed close to the counterweight 721. The sensor 73 is electrically connected to the negative pressure fan 6, and the sensor 73 is used to control the start and stop of the negative pressure fan 6.

[0076] Reference Figure 1 and Figure 6 When the counterweight block 721 moves toward the direction close to the connecting plate 31, the counterweight block 721 can collide with the sensor 73, so that the sensor 73 detects a collision signal, and then the sensor 73 transmits the collision signal to the negative pressure fan 6, thereby causing the negative pressure fan 6 to stop working.

[0077] Reference Figure 1 and Figure 6 When the counterweight 721 moves away from the connecting plate 31, the counterweight 721 no longer conflicts with the sensor 73, so that the sensor 73 does not detect the conflict signal. At this time, the negative pressure fan 6 is no longer subject to the conflict signal transmitted by the sensor, and the negative pressure fan 6 starts to work.

[0078] Reference Figure 1 A plurality of rollers 8 are also fixedly mounted on the frame 1. In this embodiment, the plurality of rollers 8 are distributed on the frame 1 in a rectangular array. The plurality of rollers 8 are all located between the two conveyor belts 22, and the plurality of rollers 8 are all arranged close to the upper conveying surface of the conveyor belt 22.

[0079] Reference Figure 1 The multiple rollers 8 cooperate with each other to guide the sheet material 5 on the conveyor belt 22, thereby facilitating the auxiliary sheet material 5 to move along the conveyor belt 22.

[0080] Reference Figure 1 In this embodiment, the plurality of rollers 8 are divided into two groups, and the two groups of rollers 8 are arranged at intervals from each other. The connecting plate 31 is located between the two groups of rollers 8, so that the connecting plate 31 can drive the sheet material 5 to move and turn.

[0081] The implementation principle of a sheet material turning device in the embodiment of the present application is as follows: when the sheet material 5 needs to be turned, the sheet material 5 is first placed on the conveyor belt 22. At this time, the negative pressure fan 6 is started to form a negative pressure in the air flow cavity 111, so that the sheet material 5 is adsorbed on the conveyor belt 22, and the sheet material 5 can be stably moved along the conveyor belt 22.

[0082] Then, the conveyor belt 22 is used to drive the sheet material 5 above the connecting plate 31. Then, the air pump 32 is started, and the air pump 32 fills the sealing sleeve 332 with gas, so that the slider 3312 drives the push rod 3311 to move away from the bogie 41. The push rod 3311 drives the connecting plate 31 to move towards the sheet material 5, and further makes the suction cup 312 be pressed on the sheet material 5. At this time, the suction cup 312 adsorbs on the sheet material 5, and the suction cup 312 drives the contact rod 72 to rotate through the limiting block 3121, and the contact rod 72 drives the counterweight 721 to move to abut against the inductor 73, so that the negative pressure fan 6 stops working.

[0083] Then, the connecting plate 31 drives the sheet material 5 to a specified position above the conveyor belt 22. At this time, the slider 3312 close to the center position of the connecting plate 31 among the two sliders 3312 abuts against the inner wall of one end of the sealing sleeve 332 close to the connecting plate 31, and the other slider 3312 continues to move towards the connecting plate 31, thereby driving the connecting plate 31 to tilt to a corresponding angle. The connecting plate 31 drives the sheet material 5 to tilt to a corresponding angle.

[0084] Finally, when the steering cylinder 4 is started, the steering cylinder 4 drives the air pump 32, the pneumatic component 33 and the connecting plate 31 to rotate through the bogie 41 respectively, and the connecting plate 31 drives the sheet material 5 to rotate to a specified angle. Then, the air pump 32 is turned off, so that the slider 3312 drives the sheet material 5 to move towards the bogie 41 through the push rod 3311 and the connecting plate 31 in sequence, and makes the sheet material 5 move to abut against the conveyor belt 22. At this time, the suction cup 312 drives the counterweight 721 to disengage from the inductor 73 through the limiting block 3121 and the contact rod 72 in sequence, so that the negative pressure fan 6 starts working again, thereby enabling the conveyor belt 22 to continue driving the sheet material 5 to move. The turning of the sheet material 5 is completed.

[0085] In addition, the production cost of the enterprise needs to be reduced, and the production cost includes the site cost. Therefore, how to reduce the occupied area of the production line and make the best use of the space of the factory building has become an important issue. In the sheet material turning device of the present application, through the mutual cooperation of the steering cylinder 4, the bogie 41, the connecting plate 31, the suction cup 312, the air pump 32 and the pneumatic component 33, the sheet material 5 can be turned in an inclined state, so that the area occupied by the sheet material 5 during turning is smaller than the area occupied by the sheet material 5 during turning on a plane. Furthermore, it is beneficial to reduce the occupied area of the turning device and achieve the purpose of making the best use of the factory building space to a certain extent.

[0086] Moreover, the sheet material 5 is in an inclined state during turning, so that the impurities on the sheet material 5 can be separated from the sheet material 5, and further it is beneficial to reduce the possibility of the adverse effects of the impurities on the sheet material 5 during the processing of the sheet material 5.

[0087] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
