Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a manipulator jig for preventing falling off. Background Art

[0002] With the continuous development of industrial automation, the application of manipulators in manufacturing is becoming more and more extensive. As an important part of the manipulator, the manipulator jig is mainly used to accurately grasp and transport various workpieces to realize the automation of the production process. An efficient and reliable manipulator jig can greatly improve production efficiency, reduce labor intensity, and ensure the stability of product quality.

[0003] In the prior art, there are great defects in the use of traditional manipulator jigs. For example, when the traditional manipulator jig is used, the manipulator holds the workpiece and transports it from one place to another. During the movement process, vibrations will occur, and it is very easy for the workpiece to fall off during the vibration process. Therefore, the utility model proposes a manipulator jig for preventing falling off to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a manipulator jig for preventing falling off.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A manipulator jig for preventing falling off, including a fixed plate and a moving plate. Two symmetrically arranged chutes are opened on the lower end surface of the fixed plate. A shock absorption mechanism for shock absorption of the moving plate is arranged in each of the two chutes. The shock absorption mechanism includes a slider slidably connected in the chute. First grooves are opened at the lower ends of the two sliders. Rotating rods are rotatably connected in the two first grooves. Two symmetrically arranged connecting blocks are fixedly connected to the upper end of the moving plate. Second grooves are opened at the upper ends of the two connecting blocks. The ends of the two rotating rods away from the sliders are respectively rotatably connected in the second grooves. A clamping mechanism for clamping the workpiece is arranged at the lower end of the moving plate. An adsorption mechanism for adsorbing the workpiece on the clamping mechanism is arranged at the upper end of the moving plate.

[0007] Preferably, the clamping mechanism includes two symmetrically arranged fixed blocks fixedly connected to the lower end of the moving plate. Electric push rods are fixedly connected to the side walls of the opposite ends of the two fixed blocks. Clamping plates are fixedly connected to the telescopic ends of the two electric push rods.

[0008] Preferably, the adsorption mechanism includes two suction cups respectively embedded in the two clamping plates. Two symmetrically arranged air pumps are fixedly connected to the upper end of the moving plate.

[0009] Preferably, air pipes are provided on the side walls of both of the air pumps, and the two air pipes are communicated with the suction cups on the same side through corrugated pipes.

[0010] Preferably, a damper is fixedly connected to the lower end of the fixing plate, and the telescopic end of the damper is fixedly connected to the upper end of the moving plate.

[0011] Preferably, the side walls of the two sliders and the inner walls of the chutes on the same side are elastically connected through springs.

[0012] Preferably, anti-slip sleeves are sleeved on both of the clamping plates, and the two anti-slip sleeves are made of rubber.

[0013] Preferably, the fixing plate and the moving plate are both made of stainless steel, and anti-corrosion coatings are sprayed on the surfaces of the fixing plate and the moving plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing a shock absorption mechanism, the telescopic ends of the electric push rods on both sides are driven to extend, driving the clamping plates on both sides to move towards the middle to clamp the workpiece. During the movement, the workpiece will vibrate. When the moving plate vibrates, it pulls the rotating rod to rotate, causing the slider to slide in the chute. Under the action of the spring, the slider is buffered, and the damper is cooperated to shock-absorb the moving plate, thereby realizing shock absorption of the workpiece and effectively avoiding the situation that the workpiece falls off due to vibration.

[0016] 2. By providing an adsorption mechanism, the telescopic ends of the electric push rods on both sides are driven to extend, driving the clamping plates on both sides to move towards the middle to clamp the workpiece. After the clamping is completed, the air pumps on both sides are started. The air pumps are communicated with the suction cups through the air pipes and the corrugated pipes. When inhaling, negative pressure is generated, which can suck the surface of the workpiece tightly, realizing adsorption of the workpiece and greatly reducing the risk of the workpiece falling off.

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific implementation manners of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0024] Refer to Figures 1-5 , a non-detachable manipulator jig, including a fixing plate 1 and a moving plate 2. The materials of the fixing plate 1 and the moving plate 2 are both stainless steel, and the surfaces of the fixing plate 1 and the moving plate 2 are both sprayed with an anti-rust coating. The anti-rust coating is paint to prevent the device from rusting. Two symmetrically arranged sliding grooves 11 are opened on the lower end surface of the fixing plate 1. A damping mechanism for damping the moving plate 2 is arranged in each of the two sliding grooves 11. The damping mechanism includes sliders 13 slidably connected in the sliding grooves 11. First grooves are opened at the lower ends of the two sliders 13. Rotating rods 10 are rotatably connected in each of the two first grooves. Two symmetrically arranged connecting blocks are fixedly connected to the upper end of the moving plate 2. Second grooves are opened at the upper ends of the two connecting blocks. The ends of the two rotating rods 10 away from the sliders 13 are respectively rotatably connected in the second grooves. A damper 12 is fixedly connected to the lower end of the fixing plate 1. The telescopic end of the damper 12 is fixedly connected to the upper end of the moving plate 2. The side walls of the two sliders 13 and the inner walls of the same-side sliding grooves 11 are elastically connected by springs 3.

[0025] A clamping mechanism for clamping a workpiece is arranged at the lower end of the moving plate 2. The clamping mechanism includes two symmetrically arranged fixing blocks 7 fixedly connected to the lower end of the moving plate 2. Electric push rods 8 are fixedly connected to the side walls of the opposite ends of the two fixing blocks 7. Clamping plates 6 are fixedly connected to the telescopic ends of the two electric push rods 8. Anti-slip sleeves are sleeved on the two clamping plates 6. The materials of the two anti-slip sleeves are both rubber.

[0026] An adsorption mechanism for adsorbing the workpiece on the clamping mechanism is provided at the upper end of the moving plate 2. The adsorption mechanism includes two suction cups 14 respectively embedded in the two clamping plates 6. Two symmetrically arranged air pumps 5 are fixedly connected to the upper end of the moving plate 2. Air pipes 4 are arranged on the side walls of the two air pumps 5. The two air pipes 4 are communicated with the suction cups 14 on the same side through corrugated pipes 9. The suction cups 14 on both sides are negative pressure suction cups. Under the action of the corrugated pipes 9, the corrugated pipes 9 can stretch and contract during the movement of the clamping plates 6 without movement interference.

[0027] When the utility model is in use, first place the workpiece between the two clamping plates 6, and then drive the telescopic ends of the electric push rods 8 on both sides to extend, driving the two clamping plates 6 to move towards the middle to clamp the workpiece. After the clamping is completed, start the air pumps 5 on both sides. The air pumps 5 are communicated with the suction cups 14 through the air pipes 4 and the corrugated pipes 9. Negative pressure is generated during suction, which can suck tightly on the surface of the workpiece to adsorb the workpiece, greatly reducing the risk of the workpiece falling off. During the movement, the workpiece will vibrate. When the moving plate 2 vibrates, it pulls the rotating rod 10 to rotate, causing the slider 13 to slide in the chute 11. Under the action of the spring 3, the slider 13 is buffered, and the damper 12 is cooperated to damp the moving plate 2, thereby damping the workpiece, effectively avoiding the situation of the workpiece falling off due to vibration.
