[0031] Such as Figures 1-8As shown in the figure, a material grabbing device of an automatic coding production line in this embodiment includes a mounting rod 1, a mounting plate 2, a cleaning unit 3 and two material grabbing units 4. The mounting rod 1 is vertically arranged, and the top end of the mounting rod 1 is externally connected to a robotic arm. The mounting plate 2 is fixedly arranged at the bottom end of the mounting rod 1. The two material grabbing units 4 are symmetrically arranged left and right at the bottom of the mounting plate 2. The cleaning unit 3 is located between the two material grabbing units 4, and the cleaning unit 3 is connected to the material grabbing unit 4;

[0032] The cleaning unit 3 includes a spray pipe 31. The spray pipe 31 is vertically arranged, and the top end of the spray pipe 31 is sealed and fixedly arranged at the bottom of the mounting plate 2. Two fixed pipes 32 are arranged on the spray pipe 31. The two fixed pipes 32 correspond to the two material grabbing units 4 one by one. The fixed pipe 32 is parallel to the left and right direction. One end of the fixed pipe 32 away from the spray pipe 31 is coaxially inserted with a pressing rod 33. The pressing rod 33 is slidably and sealingly connected to the fixed pipe 32. The fixed pipe 32 is communicated with the spray pipe 31. The pressing rod 33 is connected to the material grabbing unit 4. The material grabbing unit 4 drives the pressing rod 33 to move in the left and right direction. The material grabbing unit 4 is used to perform a turbine grabbing action;

[0033] A camera 35 is arranged at the bottom of the mounting plate 2. The camera 35 is located inside the spray pipe 31;

[0034] The material grabbing unit 4 includes a moving plate 41. The moving plate 41 is driven to move left and right by a cylinder 42. One side of the moving plate 41 close to the spray pipe 31 is connected with a clamping block 43. The pressing rod 33 is fixedly arranged on the moving plate 41;

[0035] A conduit 44 and a guide rod 45 are arranged between the clamping block 43 and the moving plate 41. The guide rod 45 is parallel to the pressing rod 33. One end of the guide rod 45 is fixedly arranged on the moving plate 41. One end of the conduit 44 is fixedly arranged on the clamping block 43. The other end of the conduit 44 is sleeved on the guide rod 45. A spring 46 is arranged inside the conduit 44. The two ends of the spring 46 are respectively connected to the guide rod 45 and the clamping block 43;

[0036] When it is necessary to clamp the workpiece, which is a turbine, the robotic arm is used to move two clamping blocks 43 so that the two clamping blocks 43 are respectively located on both sides of the workpiece, and the nozzle 31 is located directly above the workpiece. Subsequently, the cylinder 42 drives the moving plate 41 to move. The movement of the moving plate 41 drives the clamping blocks 43 to move synchronously through the guide rod 45 and the spring 46 in sequence, and the two clamping blocks 43 move closer to each other. In this way, the two clamping blocks 43 can clamp the workpiece. As the two moving plates 41 continue to move closer, relative movement is generated between the guide rod 45 and the catheter 44, and the spring 46 is deformed. Through the elastic action of the spring 46, the impact force generated when the clamping block 43 contacts the workpiece is reduced, achieving buffering. When the moving plate 41 moves a certain distance and the clamping force of the two clamping blocks 43 on the workpiece reaches the set value, it stops. Moreover, the movement of the moving plate 41 drives the extrusion rod 33 to move synchronously, so that the extrusion rod 33 extrudes the air in the fixed tube 32 into the nozzle 31. The air in the nozzle 31 is discharged from the bottom end of the nozzle 31 and acts on the workpiece. Under the action of the air flow, the impurities on the workpiece are blown away, preventing the impurities from affecting the coding effect of the workpiece;

[0037] When it is necessary to release the workpiece, the cylinder 42 drives the moving plate 41 to move in the reverse direction. The movement of the moving plate 41 drives the guide rod 45 to move synchronously. At this time, through the elastic action of the spring 46, relative movement is generated between the guide rod 45 and the catheter 44. When the relative position between the guide rod 45 and the catheter 44 is reset, the movement of the moving plate 41 drives the clamping blocks 43 to move synchronously through the guide rod 45 and the spring 46 in sequence, separating the clamping blocks 43 from the workpiece, that is, releasing the workpiece;

[0038] Of course, during the process of grasping the workpiece, the position of the workpiece is automatically recognized by taking pictures of the workpiece through the camera 35, improving the grasping accuracy;

[0039] A coaxial auxiliary tube 34 is fixedly arranged at the bottom end of the nozzle 31. The auxiliary tube 34 is cylindrical, and the large-diameter end of the auxiliary tube 34 is arranged upward. By means of the auxiliary tube 34, the gap air flow ejection aperture is adjusted, thereby increasing the air flow ejection speed and facilitating the improvement of the ability of the air flow to blow away impurities;

[0040] The clamping surface of the clamping block 43 is arc-shaped, and the side where the two clamping blocks 43 approach backward is the clamping surface;

[0041] A cavity is provided inside the clamping block 43. A plurality of adsorption holes 47 are provided on the clamping surface of the clamping block 43. The plurality of adsorption holes 47 are all communicated with the cavity. A moving box 48 is provided on the side of the moving plate 41 away from the nozzle 31. The moving box 48 is attached to the moving plate 41. A connecting pipe 49 is provided between the clamping block 43 and the moving box 48. The connecting pipe 49 is parallel to the left-right direction. The two ends of the connecting pipe 49 are respectively fixedly connected to the moving box 48 and the clamping block 43. The connecting pipe 49 movably passes through the moving plate 41. The cavity inside the clamping block 43 is connected to the moving box 48 through the connecting pipe 49. A fixing rod 40 is provided on the side of the moving plate 41 away from the nozzle 31. The fixing rod 40 is parallel to the connecting pipe 49. The fixing rod 40 is inserted into the moving box 48. The fixing rod 40 is slidably and sealingly connected to the moving box 48;

[0042] When relative movement occurs between the guide rod 45 and the conduit 44 and the distance between the clamping block 43 and the moving plate 41 decreases, relative movement is generated between the connecting pipe 49 and the moving plate 41, causing the moving box 48 to move away from the moving plate 41, that is, driving the volume of the fixing rod 40 inserted into the moving box 48 to decrease. At this time, the air in the cavity is inhaled into the moving box 48 through the connecting pipe 49, that is, the air pressure in the cavity decreases. And during the clamping of the workpiece, the clamping block 43 is in sealing contact with the workpiece. Thus, the adsorption holes 47 suck the workpiece, preventing relative movement between the workpiece and the clamping block 43 during the movement of the workpiece and affecting the placement position accuracy of the workpiece, thereby improving the coding accuracy of the workpiece;

[0043] When the relative position between the conduit 44 and the guide rod 45 is reset through the elastic action of the spring 46, the moving box 48 moves towards the moving plate 41, driving the volume of the fixing rod 40 inserted into the moving box 48 to increase, causing the air in the moving box 48 to be squeezed and conveyed to the cavity through the connecting pipe 49, restoring the air pressure in the cavity, that is, the adsorption holes 47 stop adsorbing the workpiece, enabling the clamping block 43 to release the workpiece normally;

[0044] The moving box 48 is made of rubber. The rubber has a soft texture, which facilitates buffering when the moving box 48 is attached to the moving plate 41;

[0045] The moving plate 41, the extrusion rod 33, the guide rod 45 and the fixing rod 40 are of an integrally formed structure;

[0046] In summary, the air discharged through the nozzle 31 acts on the turbine, blowing away the impurities on the turbine to prevent the impurities from affecting the coding effect of the workpiece. And, the turbine is adsorbed through the adsorption holes 47, preventing relative movement between the turbine and the clamping block 43 during the movement of the turbine, not only improving the clamping stability, but also improving the placement position accuracy of the workpiece, that is, improving the coding accuracy of the workpiece.

[0047] In addition to the above embodiments, the present utility model also includes other embodiments. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
