Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a loading and unloading device for small workpieces. Background Art

[0002] Loading and unloading devices usually use robotic arms or conveyor belts to load and unload small workpieces. For robotic arms, they can detect the position and quantity of workpieces through sensors and accurately move workpieces from one position to another. Robotic arms can automatically complete loading and unloading tasks, improving production efficiency and reducing labor costs.

[0003] In the process of loading and unloading small workpieces, the existing loading and unloading devices for small workpieces usually place the small workpieces on a conveyor belt, transport the materials to a designated location through the conveyor belt, and then other mechanical devices perform the next step of processing, which results in slow loading and unloading of small workpieces, thereby affecting the efficiency of the loading and unloading devices for small workpieces.

[0004] Therefore, a loading and unloading device for small workpieces is proposed to solve the above problems. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions, a loading and unloading device for small workpieces, comprising: a support frame, the surface of which is slidably connected to a lifting frame; a loading and unloading mechanism, which is used for quickly loading and unloading the workpiece and is arranged at the bottom of the lifting frame; wherein the loading and unloading mechanism comprises a movable plate fixedly connected to the bottom of the lifting frame, the inner wall of the movable plate is rotatably connected to a bidirectional screw rod, the surface of the bidirectional screw rod is threadedly connected to a movable block, one side of the movable block is provided with a rubber block, and the surface of the movable plate is provided with a driving assembly, the rotation of the bidirectional screw rod drives two rubber blocks to approach each other through the movable block and quickly clamps and positions the small workpiece, and the clamped and positioned small workpiece cooperates with the support frame and the lifting frame to move the small workpiece to the corresponding position.

[0007] Preferably, the driving assembly includes an air pump fixedly connected to the inner wall of the movable plate, one end of the air pump is connected to a transition pipe, one end of the transition pipe is connected to a nozzle, the surface of the nozzle is fixedly connected to the inner wall of the movable plate, and the air pump generates gas which is transported to the nozzle through the transition pipe. The gas in the nozzle begins to blow the small workpieces on the rubber block. Under the impact of the high-pressure gas, the small workpieces detach from the rubber block and fall into the loading place, thereby quickly detaching the small workpieces from the rubber block.

[0008] Preferably, a servo motor is fixedly connected to one side of the movable plate, and the output shaft of the servo motor is fixedly connected to one end of the bidirectional screw rod. The rotation of the output shaft of the servo motor can drive the two rubber blocks to move simultaneously.

[0009] Preferably, the inner wall of the movable block is fixedly connected to an air cylinder, the inner wall of the air cylinder is slidably connected to a piston rod, one end of the piston rod is fixedly connected to the surface of the rubber block, one end of the piston rod is fixedly connected to a spring, the other end of the spring is fixedly connected to one end of the inner wall of the air cylinder, one end of the air cylinder is connected to an air outlet pipe and an air inlet pipe, and the movement of the movable block drives the air cylinder, the air rod and the rubber block to move simultaneously, so that the rubber block contacts the workpiece. At this time, the movable block continues to drive the air cylinder to move toward the workpiece, and the piston rod pushes part of the gas in the air cylinder to be discharged through the air outlet pipe, so that the two rubber blocks clamp the workpiece with balanced pressure, thereby improving the effect of the loading and unloading device in clamping and positioning the workpiece.

[0010] Preferably, a first one-way valve is fixedly connected to the inner wall of the air outlet pipe, and the first one-way valve is used to block the outside air from entering the air cylinder through the air outlet pipe. The first one-way valve ensures that the gas in the air cylinder can be discharged through the air outlet pipe.

[0011] Preferably, a second one-way valve is fixedly connected to the inner wall of the air intake pipe, and the second one-way valve is used to prevent the gas in the air cylinder from being discharged through the air intake pipe. The second one-way valve is used to ensure that the gas in the air cylinder cannot be discharged through the air intake pipe.

[0012] The beneficial effects of the utility model are:

[0013] 1. The output shaft of the servo motor rotates through the bidirectional screw and the movable block to drive the air cylinder, piston rod and rubber block to move, so that the two rubber blocks are close to each other and clamp the small workpiece. At this time, the X-axis moving assembly and the Y-axis moving assembly drive the loading and unloading mechanism and the clamped workpiece to move to the loading position. After the small workpiece moves to the loading position, the air pump generates gas that is transported to the nozzle through the transition pipe. The gas in the nozzle is blown onto the small workpiece. Under the impact of high-pressure gas, the small workpiece is separated from the rubber block and falls into the loading position, making the loading and unloading of small workpieces faster and improving the efficiency of the loading and unloading device of small workpieces;

[0014] 2. The movable block drives the air cylinder, piston rod and rubber block to move, so that the rubber block contacts the workpiece. At this time, the movable block continues to drive the air cylinder to move toward the workpiece, and the piston rod pushes part of the gas in the air cylinder to be discharged through the outlet pipe, stopping the servo motor, so that the two rubber blocks clamp the workpiece with balanced pressure, improving the effect of the loading and unloading device in clamping and positioning the workpiece. The movable block drives the air cylinder, piston rod and rubber block to move away from the workpiece, and the elastic force of the spring pushes the piston rod to move. The movement of the piston rod generates suction in the air cylinder, so that the outside air enters the air cylinder through the air inlet pipe, ensuring that the corresponding gas can be stored in the air cylinder.

[0023] When it is necessary to load and unload the workpiece, the X-axis moving assembly and the Y-axis moving assembly drive the loading and unloading mechanism 3 to move onto the vibration plate, and the servo motor 30510 is started. The output shaft of the servo motor 30510 rotates to drive the bidirectional screw 303 to rotate. The bidirectional screw 303 rotates through the movable block 302 to drive the air cylinder 3055, the piston rod 3056 and the rubber block 304 to move, so that the two rubber blocks 304 are close to each other and clamp and position the small workpiece. At this time, the X-axis moving assembly and the Y-axis moving assembly drive the loading and unloading mechanism 3 and the clamped workpiece to move to the loading position. After the small workpiece moves to the loading position, the air pump 3051 is started. The gas generated by the air pump 3051 is transported to the nozzle 3053 through the transition pipe 3052. The gas in the nozzle 3053 is blown onto the small workpiece. Under the impact of the high-pressure gas, the small workpiece is separated from the rubber block 304 and falls into the loading position, so that the loading and unloading of the small workpiece is fast, and the efficiency of the small workpiece loading and unloading device is improved;
