Description

Technical Field

[0001] This utility model relates to a feeding device, specifically, to a flexible feeding device for bimetallic sheets. Background Technology

[0002] Bimetallic sheets are composite materials composed of two or more metals or other materials with suitable properties, also known as thermal bimetallic sheets. Due to the different coefficients of thermal expansion of each component layer, when the temperature changes, the deformation of the active layer is greater than that of the passive layer. The entire bimetallic sheet will bend towards the passive layer, and the curvature of this composite material will change, thus producing deformation. In the processing of bimetallic sheets, they are usually conveyed by a feeding structure. Before entering the processing station, the bimetallic sheet must meet the process requirement of having a specific surface facing upwards. Since the bimetallic sheets are randomly stacked inside the tray, it is difficult to ensure that the front of the bimetallic sheet is facing upwards. However, the traditional feeding method of bimetallic sheets is difficult to achieve efficient and reliable automatic separation and orientation recognition of stacked workpieces, which can easily lead to problems such as poor feeding and the need for manual intervention due to incorrect orientation, which seriously affects the production efficiency of bimetallic sheets. In view of this, we propose a flexible feeding device for bimetallic sheets. Utility Model Content

[0003] The purpose of this invention is to provide a flexible feeding device for bimetallic sheets to solve the problem mentioned in the background art where the low flipping efficiency of bimetallic sheets during the feeding process affects the production efficiency.

[0004] To address the aforementioned problems, the present invention provides a flexible feeding device for bimetallic strips, comprising a base plate. An identification component is provided on the upper side of the base plate to identify whether the bimetallic strip is facing upwards. From left to right, a vibration mechanism, a rotation component, and a flipping mechanism are sequentially provided on the upper side of the base plate. The vibration mechanism separates stacked bimetallic strips. The rotation component moves the bimetallic strips. The rotation component includes a fixed frame fixedly connected to the upper side of the base plate. A motor and a reducer are fixedly connected to the upper side of the fixed frame. The output shaft of the motor is coaxially connected to the input shaft of the reducer via a coupling. The output shaft of the reducer is coaxially fixedly connected to a turntable via a coupling. The rotating turntable moves the bimetallic strips. The flipping mechanism flips the bimetallic strips on the turntable. The flipping mechanism includes a mounting rod fixedly connected to the upper side of the base plate. An adjustment component and a lifting component are provided on the mounting rod. The adjustment component flips the bimetallic strips, and the lifting component places the flipped bimetallic strips onto the turntable.

[0005] As a further improvement to this technical solution, several circular placement slots are provided on the upper side of the turntable near the edge. The placement slots are used to place bimetallic strips. The diameter of the top of the placement slot is larger than the diameter of its bottom. A through hole penetrating the turntable is provided inside the placement slot.

[0006] As a further improvement to this technical solution, the adjustment assembly includes a connecting frame fixedly connected to the mounting rod near the middle position. A second cylinder is fixedly connected to the side of the connecting frame away from the mounting rod. The piston rod of the second cylinder is fixedly connected to a lifting frame. During the extension and retraction process, the piston rod of the second cylinder drives the lifting frame to move in the vertical direction.

[0007] As a further improvement to this technical solution, a movable frame is slidably connected to the side of the lifting frame away from the second cylinder, and a third cylinder and a limiting rod are fixedly connected to the side of the movable frame away from the second cylinder. The movable frame is slidably connected to the limiting rod, and the piston rod of the third cylinder is fixedly connected to the upper side of the movable frame. During the extension and retraction process, the piston rod of the third cylinder drives the movable frame to move along the axial direction of the limiting rod.

[0008] As a further improvement to this technical solution, a pneumatic motor is fixedly connected to the side of the movable frame away from the mounting rod. The rotating shaft of the pneumatic motor passes through the movable frame and is fixedly connected to the rotating frame through a coupling. A second suction nozzle is fixedly connected to the end of the rotating frame away from the movable frame. The output shaft of the pneumatic motor drives the rotating frame and the second suction nozzle to rotate.

[0009] As a further improvement to this technical solution, the lifting assembly includes a support frame fixedly connected to the top of the mounting rod. A first cylinder is fixedly connected inside the support frame. The piston rod of the first cylinder is fixedly connected to a mounting plate. A first suction nozzle is fixedly connected to the mounting plate. The first suction nozzle is located above the placement groove. During the extension and retraction process, the piston rod of the first cylinder drives the mounting plate and the first suction nozzle to move in the vertical direction.

[0010] As a further improvement to this technical solution, the vibration mechanism includes a mounting bracket fixedly connected to the upper side of the base plate, an exciter fixedly connected to the upper side of the mounting bracket, and a flexible vibrating plate provided on the upper side of the exciter. The flexible vibrating plate is used to place a bimetallic strip, and the exciter drives the bimetallic strip in the flexible vibrating plate to vibrate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The flexible feeding device for the bimetallic sheet transfers the bimetallic sheet to a turntable through a feeding structure. The turntable rotates 90 degrees, moving the bimetallic sheet below the identification component. The identification component identifies whether the bimetallic sheet is facing up. Subsequently, the turntable rotates 90 degrees, moving the bimetallic sheet below the flipping mechanism. If the bimetallic sheet is facing down, the adjustment component flips the bimetallic sheet, and the lifting component transfers the flipped bimetallic sheet into the placement slot, thus ensuring the bimetallic sheet is facing up. This efficiently and reliably completes the flipping of the bimetallic sheet, thereby improving the processing efficiency of the bimetallic sheet. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide a flexible feeding device for bimetallic strips, including a base plate 1. From left to right, a vibration mechanism 2, a rotating component, and a flipping mechanism 3 are arranged on the upper side of the base plate 1. The vibration mechanism 2 is used to separate stacked bimetallic strips. A shooting component is provided above the vibration mechanism 2 to take pictures of the bimetallic strips on the vibration mechanism 2 and identify individual bimetallic strips. A feeding structure is provided on one side of the rotating component to transfer individual bimetallic strips on the vibration mechanism 2 to the rotating component. The rotating component is used to drive the bimetallic strips to move. An identification component is provided on the upper side of the base plate 1 to identify whether the bimetallic strip is facing upwards. Both the shooting component and the identification component include cameras. The cameras are connected to a computer, and the images captured by the cameras are transmitted to the computer for processing.

[0028] The camera of the imaging component is installed on the upper side of the vibration mechanism 2. The image captured by the camera is transmitted to the computer. The computer identifies the position of the bimetallic strip in the vibration mechanism 2. The camera of the identification component is installed on the upper side of the rotating component. The image captured by the camera is transmitted to the computer. The computer determines whether the bimetallic strip is facing up. If the reverse side of the bimetallic strip is facing up, the bimetallic strip on the rotating component is flipped by the flipping mechanism 3 so that the face of the bimetallic strip is facing up. The above-mentioned techniques for identifying the face and position of the bimetallic strip by image recognition are commonly used by those skilled in the art and will not be described in detail here.

[0029] The flipping mechanism 3 includes a mounting rod 31 fixedly connected to the upper side of the base plate 1. The mounting rod 31 is equipped with an adjustment component and a lifting component. The adjustment component is used to flip the bimetallic strip, and the lifting component is used to place the flipped bimetallic strip on the rotating component. A feeding structure is provided on one side of the rotating component. Both the feeding structure and the feeding structure are robotic arms, and negative pressure suction nozzles are installed on the robotic arms. Both the feeding structure and the feeding structure use suction nozzles to pick up and transfer the bimetallic strip. The feeding structure puts the bimetallic strip from the vibration mechanism 2 onto the rotating component. After the bimetallic strip is flipped, the bimetallic strip on the rotating component is removed by the external feeding structure for subsequent processing. The feeding structure, the shooting component, the flipping mechanism 3, and the feeding structure are arranged in a cross shape on the four sides of the rotating component.

[0030] refer to Figure 1 - Figure 4 The vibration mechanism 2 includes a mounting frame 21 fixedly connected to the upper side of the base plate 1. A vibrator 22 is fixedly connected to the upper side of the mounting frame 21. A flexible vibrating plate 23 is provided on the upper side of the vibrator 22. The flexible vibrating plate 23 is used to place bimetallic strips. The vibrator 22 drives the bimetallic strips in the flexible vibrating plate 23 to vibrate, causing the bimetallic strips stacked on the upper part of the flexible vibrating plate 23 to separate. At this time, the separated bimetallic strips are in a horizontal state, so that the suction nozzle of the loading robot can adsorb and transfer the bimetallic strips.

[0031] refer to Figure 5 The rotating assembly includes a fixed frame 11 fixedly connected to the upper side of the base plate 1. A motor and a reducer 12 are fixedly connected to the upper side of the fixed frame 11. The output shaft of the motor is coaxially connected to the input shaft of the reducer 12 via a coupling. The output shaft of the reducer 12 is coaxially fixedly connected to a turntable 13 via a coupling. The rotating output shaft of the motor drives the turntable 13 to rotate through the reducer 12. The turntable 13 rotates 90 degrees each time. Several circular placement slots 14 are provided on the upper side of the turntable 13 near the edge. In this design, there are four placement slots 14. The placement slots 14 are used to place bimetallic strips. The diameter of the top of the placement slot 14 is larger than the diameter of its bottom to enlarge the opening at the top of the placement slot 14, which facilitates... The loading robot places the bimetallic strip inside the placement groove 14. The size of the bimetallic strip is adapted to the size of the bottom of the placement groove 14. After the bimetallic strip is placed inside the placement groove 14, it contacts the bottom of the inner wall of the placement groove 14 to reduce the probability of the bimetallic strip shaking inside the placement groove 14. The placement groove 14 has a through hole that passes through the turntable 13. The diameter of the through hole is smaller than the diameter of the bottom of the placement groove 14 to prevent the bimetallic strip from passing through the through hole and detaching from the inside of the placement groove 14. The through hole connects the placement groove 14 to the outside to prevent the bimetallic strip from forming a negative pressure space with the bottom of the placement groove 14, ensuring that the loading robot and unloading robot can pick up and transfer the bimetallic strip.

[0032] refer to Figure 1 - Figure 4 and Figure 6 The adjustment assembly includes a connecting frame 33 fixedly connected to the mounting rod 31 near its center. A second cylinder 331 is fixedly connected to the side of the connecting frame 33 away from the mounting rod 31. A lifting frame 332 is fixedly connected to the piston rod of the second cylinder 331. During the extension and retraction of the piston rod of the second cylinder 331, the lifting frame 332 moves vertically. A movable frame 334 is slidably connected to the side of the lifting frame 332 away from the second cylinder 331. A third cylinder 333 and a limiting rod 338 are fixedly connected to the side of the movable frame 334 away from the second cylinder 331. The movable frame 334 is slidably connected to the limiting rod 338. The piston rod of the third cylinder 333 is fixedly connected to the upper side of the movable frame 334. During the extension and retraction process, the movable frame 334 is moved along the axis of the limiting rod 338. A pneumatic motor 335 is fixedly connected to the side of the movable frame 334 away from the mounting rod 31. The output shaft of the pneumatic motor 335 can rotate in both directions. The pneumatic motor 335 is existing technology and will not be improved in this solution. It will not be described here. The rotating shaft of the pneumatic motor 335 passes through the movable frame 334 and is fixedly connected to the rotating frame 336 through a coupling. The rotation angle of the rotating frame 336 is 180 degrees. A second suction nozzle 337 is fixedly connected to the end of the rotating frame 336 away from the movable frame 334. The output shaft of the pneumatic motor 335 rotates the rotating frame 336 and the second suction nozzle 337. The rotating frame 336 is in a vertical state in both the initial and final states.

[0033] In addition, the lifting assembly includes a support frame 32 fixedly connected to the top of the mounting rod 31. A first cylinder 321 is fixedly connected inside the support frame 32. The piston rod of the first cylinder 321 is fixedly connected to the mounting plate 322. A first suction nozzle 323 is fixedly connected to the mounting plate 322. The first suction nozzle 323 is located above the placement groove 14. During the extension and retraction process, the piston rod of the first cylinder 321 drives the mounting plate 322 and the first suction nozzle 323 to move in the vertical direction.

[0034] When it is necessary to flip the bimetallic strip inside the placement slot 14, the second suction nozzle 337 faces downwards. The piston rod of the third cylinder 333 extends, driving the moving frame 334 and the second suction nozzle 337 to move, so that the second suction nozzle 337 moves above the placement slot 14. The piston rod of the second cylinder 331 extends, driving the lifting frame 332 and the second suction nozzle 337 to move downwards, so that the second suction nozzle 337 contacts the bimetallic strip and adsorbs it. The piston rod of the second cylinder 331 retracts, driving the lifting frame 332, the second suction nozzle 337, and the bimetallic strip to move upwards, removing the bimetallic strip from inside the placement slot 14. Subsequently, the output shaft of the pneumatic motor 335 rotates, driving the rotating frame 336 and the second suction nozzle 337 to rotate 180 degrees to remove the bimetallic strip. The plate flips over, at which point the second suction nozzle 337 is in a vertical position, and the bimetallic strip is located between the second suction nozzle 337 and the first suction nozzle 323. The piston rod of the first cylinder 321 extends and drives the mounting plate 322 and the first suction nozzle 323 to move downward, so that the first suction nozzle 323 contacts the bimetallic strip and adsorbs it. After the first suction nozzle 323 adsorbs the bimetallic strip, the second suction nozzle 337 releases its adsorption on the bimetallic strip. The second cylinder 331 and the third cylinder 333 drive the second suction nozzle 337 away from the bimetallic strip. Subsequently, the piston rod of the first cylinder 321 extends and drives the mounting plate 322, the first suction nozzle 323 and the bimetallic strip to move downward, transferring the bimetallic strip into the placement groove 14 and releasing the adsorption of the first suction nozzle 323 on it.

[0035] The first cylinder 321, the first suction nozzle 323, the second cylinder 331, the third cylinder 333, the second suction nozzle 337, and the pneumatic motor 335 are all connected to an external air pump via air pipes. When the pneumatic motor 335 drives the rotating frame 336 and the second suction nozzle 337 to rotate 180 degrees and needs to be reset, the output shaft of the pneumatic motor 335 rotates in the opposite direction to drive the rotating frame 336 and the second suction nozzle 337 to rotate and reset. This prevents the rotating frame 336 and the second suction nozzle 337 from rotating in one direction, which would cause the air pipes to become entangled, and ensures that the second suction nozzle 337 can be used normally.

[0036] When using this device:

[0037] In the initial state, the second suction nozzle 337 faces downwards, and the first suction nozzle 323 is located above the second suction nozzle 337. During the bimetallic sheet processing, the bimetallic sheet is placed by the flexible vibrating plate 23, and the vibrator 22 drives the bimetallic sheet in the flexible vibrating plate 23 to vibrate, causing some of the stacked bimetallic sheets to separate. Subsequently, the imaging component identifies the bimetallic sheet in a separate position on the flexible vibrating plate 23, and the feeding structure transfers the bimetallic sheet into the placement groove 14.

[0038] The output shaft of the external motor rotates and drives the turntable 13 to rotate 90 degrees through the reducer 12, so that the bimetallic strip is moved to the bottom of the identification component. The identification component determines whether the bimetallic strip is facing up. The turntable 13 rotates to move the bimetallic strip to the bottom of the first suction nozzle 323.

[0039] If the bimetallic strip is facing up, the piston rod of the third cylinder 333 extends and moves the second suction nozzle 337 above the placement slot 14 via the moving frame 334. The output shaft of the pneumatic motor 335 rotates and drives the second suction nozzle 337 to rotate via the rotating frame 336. The piston rod of the second cylinder 331 extends and moves the second suction nozzle 337 downward via the lifting frame 332 to adsorb the bimetallic strip.

[0040] Subsequently, the piston rod of the second cylinder 331 retracts, driving the second suction nozzle 337 and the bimetallic strip upward through the lifting frame 332. The output shaft of the pneumatic motor 335 rotates in the opposite direction, driving the rotating frame 336 and the second suction nozzle 337 to rotate and flip the bimetallic strip. The piston rod of the first cylinder 321 extends, driving the first suction nozzle 323 to adsorb the bimetallic strip through the mounting plate 322. At this time, the second suction nozzle 337 releases the adsorption of the bimetallic strip and drives it away from the bimetallic strip through the second cylinder 331 and the third cylinder 333. The piston rod of the first cylinder 321 extends, driving the first suction nozzle 323 and the bimetallic strip downward through the mounting plate 322, transferring the bimetallic strip into the placement slot 14 and releasing the adsorption.

[0041] After the bimetallic strip is flipped, the turntable 13 rotates and moves the bimetallic strip. The flipped bimetallic strip is then removed from the turntable 13 by the feeding structure.

[0042] After turntable 13 stops rotating, the feeding structure, shooting component, flipping mechanism 3 and unloading structure work synchronously to improve the feeding efficiency of bimetallic strips.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
