Description

Technical Field

[0001] This utility model relates to gripper technology, specifically a workpiece anti-fall mechanism. Background Technology

[0002] With the continuous advancement and development of science and technology, industrial automation is gradually becoming a key force driving productivity improvement and economic development. In this wave of automation, grippers, as a commonly used industrial tool, are actively leading the intelligent revolution in industrial automation.

[0003] Existing grippers typically use a cylinder to drive two jaws to move in opposite directions to clamp the workpiece. However, when the workpiece is cylindrical, the jaws can only limit the area they contact, leaving the rest suspended. This results in limited clamping effectiveness. Consequently, during handling and movement, the workpiece may tilt or shift due to inertia or collisions, causing it to detach from the jaws and fall, resulting in damage. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a workpiece anti-fall mechanism, which adds a suction cup to limit the top of the workpiece and works with two jaws to achieve three-point positioning, resulting in good clamping effect and preventing the workpiece from falling off the jaws.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a workpiece anti-fall mechanism, comprising a base, an electric cylinder, a transmission unit and two jaws, the two jaws being located on both sides of the transmission unit, the electric cylinder and the transmission unit being disposed above the base, the electric cylinder driving the two jaws to move through the transmission unit to clamp the two sides of the workpiece, and a suction cup being provided below the base for adsorbing the top of the workpiece;

[0006] The transmission unit includes two movable plates and a guide assembly. The guide assembly is located on the base. The two movable plates are located on both sides of the guide assembly and are fixed to the chucks. The movable plates are provided with guide grooves and mounting plates on both sides. The two mounting plates are fixed to the end of the electric cylinder and the end of the electric cylinder output shaft, respectively. A guide post is slidably fitted in the guide groove. The guide post is fixed to one end of the linkage plate. A gear is fixed to the other end of the linkage plate. The gear is rotatably connected to the base, and the two gears mesh with each other.

[0007] Preferably, the guide assembly includes a slide rail and a plurality of sliders, the sliders being fixed below the movable plate, the sliders being slidably engaged with the slide rail, and the slide rail being fixed to the base.

[0008] Preferably, the base is provided with a flange plate, the base and the flange plate are arranged perpendicularly, and the flange plate is provided with a connecting shaft.

[0009] Preferably, the base is provided with a barcode scanner on the side opposite to the flange plate.

[0010] Preferably, a camera is provided between the flange plate and the barcode scanner.

[0011] In summary, this utility model achieves the following technical effects:

[0012] The workpiece anti-fall mechanism of this utility model is equipped with a suction cup. The suction cup limits the top of the workpiece, and the two jaws hold the two sides of the workpiece to achieve three-point positioning. The clamping effect is good, and even if the workpiece is detached from the jaws, it will be sucked in by the suction cup to prevent the workpiece from falling during the transportation process.

[0022] Example 1:

[0023] like Figure 1 As shown in Figure 2, a workpiece anti-fall mechanism includes a base 1, an electric cylinder 11, a transmission unit, and two jaws 3. The two jaws 3 are located on both sides of the transmission unit. The electric cylinder 11 and the transmission unit are both located above the base 1. The electric cylinder 11 drives the two jaws 3 to move through the transmission unit to clamp the two sides of the workpiece. A suction cup 2 is provided below the base 1. The suction cup 2 is used to adsorb the top of the workpiece.

[0024] In this embodiment, the workpiece anti-fall mechanism is equipped with a suction cup 2. The suction cup 2 limits the top of the workpiece, and the two jaws 3 clamp the two sides of the workpiece to achieve three-point positioning. The clamping effect is good, and even if the workpiece is detached from the jaws 3, it will be sucked by the suction cup 2 to prevent the workpiece from falling during the transportation process.

[0025] The transmission unit includes two movable plates 4 and a guide assembly. The guide assembly is located on the base 1. The two movable plates 4 are located on both sides of the guide assembly and are fixed to the pawls 3 respectively. The movable plates 4 are provided with guide grooves 7 and mounting plates 10 on both sides respectively. The two mounting plates 10 are fixed to the end of the electric cylinder 11 and the end of the output shaft of the electric cylinder 11 respectively. A guide post is slidably fitted in the guide groove 7. The guide post is fixed to one end of the linkage plate 8. A gear 9 is fixed to the other end of the linkage plate 8. The gear 9 is rotatably connected to the base 1. The two gears 9 mesh with each other.

[0026] When the electric cylinder 11 is energized, the output shaft extends or retracts, which causes the mounting plate 10 connected to the output shaft to move. The moving plate 4 moves simultaneously, driving the guide groove 7 to move. The guide post is moved by the guide groove 7, which in turn causes the linkage plate 8 and gear 9 to rotate in the direction of movement. Since the two gears 9 mesh, the other linkage plate 8 rotates in the opposite direction. Through the transmission of the guide post and guide groove 7, the other moving plate 4 moves, thereby enabling the two moving plates 4 to move closer and further apart, which in turn drives the two chucks 3 to clamp and release the workpiece.

[0027] The guiding component includes a slide rail 5 and several sliders 6. The sliders 6 are fixed below the movable plate 4 and slide in conjunction with the slide rail 5. The slide rail 5 is fixed to the base 1.

[0028] The base 1 is provided with a flange plate 14, which is perpendicular to the base 1 and the flange plate 14. The flange plate 14 is provided with a connecting shaft 15. The connecting shaft 15 can be connected to an industrial robot or a handling device.

[0029] The base 1 is provided with a barcode scanner 13 on the side opposite to the flange plate 14; the barcode scanner 13 is used to scan the QR code on the workpiece.

[0030] A camera 12 is provided between the flange plate 14 and the barcode scanner 13. The camera 12 is used to capture image information of the workpiece.

[0031] The barcode scanner 13 and camera 12 are generally located above the base 1. In actual use, the robot can rotate the entire mechanism so that the barcode scanner 13 and camera 12 face down to determine the workpiece information and the chuck 3 faces up. After determining the workpiece information, the robot rotates the entire mechanism 180 degrees so that the chuck 3 faces down.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
