[0021] like Figures 1 to 5 As shown, the utility model provides a four-axis robot arm, including a rotating seat 1 and a grab plate 4, the left and right sides of the grab plate 4 are fixedly installed with support plates 7, the top of the support plate 7 is fixedly connected with a servo motor 8, the output shaft of the servo motor 8 is fixedly sleeved with a rotating disk 9, the bottom end of the rotating disk 9 is movably sleeved with a reciprocating sleeve rod 10, the reciprocating sleeve rod 10 is fixedly installed with a piston rod 11 on the side away from the support plate 7, the top of the support plate 7 is fixedly installed with a piston cylinder 12, the bottom end of the piston cylinder 12 is fixedly installed with a one-way air outlet component 17, the bottom end of the one-way air outlet component 17 is fixedly connected with a dust blowing bin 18, and the side of the reciprocating sleeve rod 10 away from the piston cylinder 12 is fixedly installed with a guide telescopic rod 19;
[0022] The servo motor 8 is started to drive the rotating disk 9 to rotate. During the rotation of the rotating disk 9, the reciprocating sleeve rod 10 is driven to move in the inner cavity of the piston cylinder 12 along the axial direction of the piston rod 11 and the guide telescopic rod 19, so that the air in the inner cavity of the piston cylinder 12 is squeezed by the piston rod 11, and the squeezed air enters the inner cavity of the dust blowing bin 18 along the one-way air outlet component 17, and then is sprayed to the surface of the material through the dust blowing bin 18, so as to clean the dust and debris on the surface of the material, thereby ensuring the hygiene and cleanliness of the inside of the grabbing rod 6.
[0023] The piston cylinder 12 is fixedly connected to a one-way air intake assembly 13 on one side away from the one-way air intake pipe 21, the bottom end of the one-way air intake assembly 13 is fixedly connected to a telescopic cylinder 14, the bottom end of the telescopic cylinder 14 is fixedly connected to a suction nozzle 15, and a spring assembly 16 is arranged on the outside of the telescopic cylinder 14;
[0024] The suction nozzle 15 contacts the surface of the material, and the suction nozzle 15 is displaced by the spring assembly 16, so that the suction nozzle 15 is closely fitted to the surface of the smooth material. Then, when the piston rod 11 moves in the inner cavity of the piston cylinder 12, the air in the inner cavity of the telescopic cylinder 14 is extracted through the one-way air intake assembly 13, thereby forming a negative pressure between the suction nozzle 15 and the material, and then the suction nozzle 15 adsorbs the material, thereby preventing the smooth surface of the material from slipping between the grab bars 6, thereby improving stability.
[0025] Among them, a horizontal movable seat 2 is arranged at the top of the rotating seat 1, a lifting assembly 3 is arranged inside the horizontal movable seat 2, and the bottom end of the lifting assembly 3 is connected to the grabbing plate 4;
[0026] The rotating seat 1 drives the horizontal movable seat 2 to rotate, so that the grab plate 4 can drive the material to move. Then, the horizontal movable seat 2 drives the lifting component 3 to move along the axial direction of the horizontal movable seat 2, and then the lifting component 3 drives the grab plate 4 to rise and fall along the axial direction of the lifting component 3, so that the material is transferred to the appropriate required position through the combination of multiple directions of movement.
[0027] The bottom end of the grab plate 4 is fixedly connected to a cylinder 5, and the output shaft of the cylinder 5 is fixedly sleeved with a grab rod 6;
[0028] By starting the cylinder 5 at the bottom end of the grab plate 4 to drive the grab rod 6 to move along the axial direction of the cylinder 5, the spacing of the grab rod 6 can be changed, and the material can be grabbed by the grab rod 6.
[0029] Among them, a positioning rod is fixedly installed at the bottom end of the rotating disk 9, and the reciprocating sleeve rod 10 is movably sleeved on the surface of the positioning rod;
[0030] Through the positioning rod at the bottom end of the rotating disk 9, the reciprocating sleeve rod 10 can be movably sleeved on the surface of the positioning rod, so that the rotating disk 9 can drive the reciprocating sleeve rod 10 to move back and forth through the positioning rod during the rotation process.
[0031] Among them, the one-way air outlet component 17 is composed of a round tube and a one-way air outlet valve, and the one-way air inlet component 13 is composed of a round tube and a one-way air inlet valve;
[0032] Through the setting of the one-way air outlet component 17, the air on the side of the piston rod 11 in the inner cavity of the piston cylinder 12 close to the one-way air inlet pipe 21 is squeezed by the piston rod 11 and blown out from the dust blowing bin 18 along the one-way air outlet component 17, thereby cleaning the material. Then, through the setting of the one-way air inlet component 13, the air in the inner cavity of the telescopic cylinder 14 is drawn out to the inner cavity of the piston cylinder 12 along the one-way air inlet component 13, so that negative pressure is formed between the suction nozzle 15 and the smooth material.
[0033] The spring assembly 16 is composed of fixing rings at the upper and lower ends and a supporting spring in the middle, and the two fixing rings are fixedly connected to the telescopic cylinder 14 and the adsorption nozzle 15 respectively;
[0034] By setting the fixing ring, the fixing ring can be installed and connected to the supporting spring, and by setting the two fixing rings, the telescopic cylinder 14 and the adsorption nozzle 15 can support the spring to move.
[0035] The working principle and use process of the utility model are as follows: the rotating seat 1 drives the horizontal movable seat 2 to rotate with the rotating seat 1 as the axis, and then the horizontal movable seat 2 drives the lifting assembly 3 to move along the axis direction of the horizontal movable seat 2, and then the lifting assembly 3 drives the grab plate 4 to move up and down along the axis direction of the lifting assembly 3;
[0036] When the lifting assembly 3 drives the grab plate 4 to grab the material, the servo motor 8 is first started to drive the rotating disk 9 to rotate, and the piston rod 11 is driven by the rotating disk 9 to move along the axial direction of the guide telescopic rod 19 and the piston cylinder 12. When the piston rod 11 moves in the inner cavity of the piston cylinder 12, the air is squeezed and extracted. First, the air is discharged from the dust blowing bin 18 through the one-way air outlet assembly 17, and then blown onto the surface of the material to blow away the dust on the surface of the material. Then, the air in the inner cavity of the piston cylinder 12 and the side of the piston rod 11 close to the one-way air inlet pipe 21 is supplemented with air.
[0037] Then the suction nozzle 15 contacts the surface of some smooth materials, and through the setting of the spring assembly 16, the suction nozzle 15 can be movable, so that the suction nozzle 15 can be subjected to the tension of the spring assembly 16 and fit closely to the surface of the material, and then through the movement of the piston rod 11 in the inner cavity of the piston cylinder 12, the air in the inner cavity of the suction nozzle 15 is extracted through the telescopic cylinder 14 and the one-way air inlet assembly 13 to enter the piston rod 11 and then discharged through the one-way air outlet pipe 20, so that negative pressure is formed between the suction nozzle 15 and the material, thereby performing negative pressure adsorption on the smooth material.
