[0024] See also Figure 1-6 The utility model provides a bottle loading and unloading mechanical arm, comprising a main frame 1 and a driving motor 2 and an auxiliary motor 3 installed on one side of the main frame 1. A support seat 4 is provided on one side of the main frame 1. Two driving arms 5 are installed between the main frame 1 and the support seat 4. The output shaft of the driving motor 2 passes through the main frame 1 and is fixedly connected to one driving arm 5. The output shaft of the auxiliary motor 3 passes through the main frame 1 and is fixedly connected to the other driving arm 5. The outsides of the two driving arms 5 are both rotatably connected with driven rods 6. The ends of the two driven rods 6 away from the driving arms 5 are rotatably connected through a rotating shaft. The two driving arms 5 and the two driven rods 6 form a quadrilateral structure;

A rotating motor 8 is installed on the surface of the mounting plate 7 by bolts. A connecting mechanism is provided on one side of the rotating motor 8. The connecting mechanism consists of two connecting blocks 9 and a fixing block 10 fixed to one side of the connecting block 9. One connecting block 9 is fixedly connected to the output end of the rotating motor 8, and the other connecting block 9 is rotatably connected to one end of the driven rod 6. The rotating motor 8 drives one connecting block 9 to rotate, and the other connecting block 9 rotates at the same time, thereby driving the fixing block 10 to rotate;

[0026] A connection box 11 is installed at the bottom of the fixed block 10 by bolts, a dual-axis motor 12 is installed at the bottom wall of the inner cavity of the connection box 11 by bolts, and guide screws 13 are fixed to the two output ends of the dual-axis motor 12 by couplings, the thread grooves of the two guide screws 13 run in opposite directions, and the outer wall of the guide screw 13 is threadedly connected with a guide block 14, and two guide grooves for the guide block 14 to move are symmetrically opened at the bottom of the connection box 11;

[0027] A movable groove is provided at the bottom of the guide block 14, and a positioning block 15 is movably connected in the movable groove at the bottom of the guide block 14, a clamping arm 16 is fixed to the bottom of the positioning block 15 by bolts, a through hole is provided on one side of the outer wall of the guide block 14, and a fixing pin 17 is movably connected in the through hole of the guide block 14, a fixing hole matching the fixing pin 17 is provided on the positioning block 15, a limiting ring 18 is fixed on the outer wall of the fixing pin 17, and a fixing spring 19 for supporting the limiting ring 18 is sleeved on the outside of the fixing pin 17, and protective pads are bonded to the opposite surfaces of the two clamping arms 16;

[0028] The driving motor 2 drives one driving arm 5 to move, and the auxiliary motor 3 drives the other driving arm 5 to move. Because the two driving arms 5 and the two driven rods 6 form a quadrilateral, when the two driving arms 5 move, the two driven rods 6 are driven to move at the same time. When clamping, the formed quadrilateral does not change. When moving, the quadrilateral is compressed to move laterally, so that the clamping arm 16 moves.

[0029] By operating the dual-axis motor 12, the two guide screws 13 can be driven to move toward or oppositely at the same time. According to the size of the bottle, the distance between the two clamping arms 16 can be adjusted, and bottles of different sizes can be effectively fixed. By rotating the motor 8 to drive one connecting block 9 to rotate, the other connecting block 9 rotates at the same time, thereby driving the fixing block 10 to rotate, and the fixing block 10 drives the connecting box 11 and the clamping arm 16 to rotate, automatically adjusting the angle of the bottle, so that the bottle can be placed more stably on the subsequent conveyor line, and the positioning block 15 is inserted into the guide block 14. The fixing spring 19 supports the limit ring 18 so that the fixing pin 17 is inserted into the fixing hole of the positioning block 15.

[0032] Working principle:

[0033] When the bottle loading and unloading robot arm is in use, the driving motor 2 drives one driving arm 5 to move, and the auxiliary motor 3 drives the other driving arm 5 to move. When the two driving arms 5 move, the two driven rods 6 are driven to move at the same time, thereby driving the clamping arm 16 to move. The rotary motor 8 drives the connecting box 11 to rotate, adjusts the angle of the clamping arm 16, and moves the clamping arm 16 to the position of the bottle, and the two clamping arms 16 are located on both sides of the bottle;

[0034] Start the double-axis motor 12 to drive the two guide screws 13 to rotate, so that the two guide blocks 14 and the clamping arms 16 move toward each other, and the two clamping arms 16 clamp on both sides of the bottle to fix the position of the bottle. The driving motor 2 and the auxiliary motor 3 rotate in the opposite direction to move the bottle in the clamping arm 16 to the conveyor line. The double-axis motor 12 rotates in the opposite direction, the two clamping arms 16 separate from each other, and the bottle falls on the conveyor line, completing the unloading operation of the bottle.
