Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-4 , a manipulator for a plastic injection molding machine includes a base 1 and a drive unit 2 fixed to the top of the base 1 capable of performing XYZ-axis driving. The X-axis, Y-axis, and Z-axis of the drive unit 2 are all driven by lead screw modules. A mounting sleeve 3 is fixed to the bottom of the Z-axis driving component of the drive unit 2, and a mechanical gripper 4 is detachably connected to the bottom of the mounting sleeve 3. An electric drive locking disassembly mechanism 5 is provided between the mechanical gripper 4 and the mounting sleeve 3, and an anti-disengagement mechanism 6 for mechanically locking the mechanical gripper 4 is provided between the mounting sleeve 3 and the mechanical gripper 4; in this new type of manipulator, the drive motor 71 drives the screw 72 to rotate, which can drive the clamping post 73 to insert into the through hole 53 of the protruding part 52 at the top of the mechanical gripper 4, and the mechanical gripper 4 can be conveniently disassembled and assembled. When removing the mechanical gripper, the L-shaped plates 61 on both sides can prevent the mechanical gripper from accidentally falling due to the negligence of the staff, ensuring the use safety while facilitating disassembly.

[0021] In this embodiment, the disassembly mechanism 5 includes a groove 51 opened at the bottom of the mounting sleeve 3 and a protruding part 52 fixed to the top of the mechanical gripper 4. A through hole 53 is opened on the surface of the protruding part 52. A fixed cylinder 54 is fixed to the front of the mounting sleeve 3, and an electric locking mechanism 7 is provided between the fixed cylinder 54 and the through hole 53. The protruding part 52 can be fitted into the groove 51 to facilitate the connection between the mechanical gripper 4 and the mounting sleeve 3.

[0022] Further, the electric locking mechanism 7 includes a driving motor 71 fixed to the inner wall of the fixed cylinder 54. A screw rod 72 is fixed to the output shaft of the driving motor 71. A connecting sleeve 74 is threadedly connected to the surface of the screw rod 72. The other end of the connecting sleeve 74 is fixed with a clamping post 73. The clamping post 73 is movably connected to the through hole 53. By driving the screw rod 72 to rotate through the driving motor 71, the clamping post 73 can be driven to insert into the through hole 53 of the protruding portion 52 at the top of the mechanical gripper 4.

[0023] Furthermore, guide posts 8 are fixed to both sides of the connecting sleeve 74. Sliding grooves 9 are formed on both sides of the fixed cylinder 54. The sliding grooves 9 are slidably connected to the guide posts 8. The guide posts 8 cooperating with the sliding grooves 9 can guide the connecting sleeve 74 and the clamping post 73.

[0024] In addition, the anti-detachment mechanism 6 includes moving grooves 64 formed on both sides of the bottom of the mounting sleeve 3 and L-shaped plates 61 slidably connected to the inner sides of the moving grooves 64. The outer ends of the L-shaped plates 61 are fixed with pull rods 62 that penetrate and extend to the outside of the mounting sleeve 3. A spring 63 is sleeved on the surface of the pull rod 62. The two ends of the spring 63 are respectively in contact with the L-shaped plate 61 and the moving groove 64. The L-shaped plates 61 on both sides can prevent the mechanical gripper 4 from accidentally falling due to the negligence of the staff.

[0025] It should be noted that at least two guide strips 10 are fixed to the inner walls of the moving grooves 64. The at least two guide strips 10 are slidably connected to both sides of the L-shaped plate 61 for position. Fitting grooves 11 that fit the L-shaped plates 61 are formed on both sides of the mechanical gripper 4. The guide strips 10 can limit and guide the L-shaped plates 61 to make them slide smoothly.

[0026] Working mode: When disassembling and assembling the mechanical gripper 4, the staff turns on the driving motor 71. The driving motor 71 drives the screw rod 72 to rotate. The screw rod 72 can drive the connecting sleeve 74 and the clamping post 73 to disengage from the through hole 53 on the protruding portion 52. After disengagement, the two L-shaped plates 61 can hold the mechanical gripper 4 to prevent it from falling. Then, the staff can pull the pull rod 62 outward. The pull rod 62 can drive the L-shaped plate 61 to compress the spring 63 so that the L-shaped plate 61 disengages from the fitting groove 11. At this time, the staff can completely remove the mechanical gripper 4.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
