The first telescopic cylinder is fixedly mounted on the connecting rod through the inlay connecting plate, and its piston rod is connected to the second telescopic cylinder. The piston rod of the second telescopic cylinder extends away from the connecting rod to connect to the first inlay gripper, and the second inlay gripper is mounted on the cylinder seat of the second telescopic cylinder, opposite to the first inlay gripper.
[0006] Furthermore, the product gripper includes a first product gripper and a second product gripper of the same structure. Each product gripper includes a third telescopic cylinder and a clamping claw.

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and a preferred embodiment.
[0018] See Figure 1-Figure 3 A multifunctional die-casting picking robot gripper includes a connecting rod 1, a first product gripper 11, a second product gripper 12, a material handle gripper 20 and an inlay component 30.
[0019] Connecting rod 1 is used to attach the product gripper, handle gripper, and inlay assembly, as well as connect to the robot. In this embodiment, connecting rod 1 is a rectangular body enclosed by steel plates on all four sides, with an open top and rear end. The front of the rectangular body is equipped with a quick-connect module for connecting the air pipe and cable, and the rear side is equipped with the product gripper. The front side of the rectangular body is used to connect to the robot, and the upper end of the front side is connected to an L-shaped bracket 2 for securing the air pipe.
[0020] The first and second product grippers 11, 12 have identical structures. For example, the first product gripper 11 comprises a third telescopic cylinder 111 and a clamping jaw. The end of the clamping jaw extending from the connecting rod is equipped with a contouring block 112 that aligns with the product. The piston rods of the two third telescopic cylinders for the first and second product grippers 11, 12 are mounted horizontally within the connecting rod, facing each other. These piston rods extend outwards from either side of the connecting rod to connect to two clamping jaws. The upper portions of the two clamping jaws extend from the open end of the connecting rod to grip the product. When the piston rods of the two third telescopic cylinders extend, the two clamping jaws extend outwards, opening the jaws. When the piston rods of the two third telescopic cylinders retract, the two clamping jaws retract, clamping the jaws.
[0021] The material handle gripper 20 comprises a clamping cylinder and two identically structured clamping fingers. The clamping cylinder is fixed to the rear end of the bottom surface of the connecting rod 1 via screws. The cylinder piston rod extends horizontally forward and pivots to connect to two rockers. The other ends of the two rockers pivot to connect to the two clamping fingers. The middle portion of the two clamping fingers is rotatably mounted on the cylinder body of the clamping cylinder via a bracket. The rear end is hinged to the rocker, and the front end extends forward to form a clamping portion. The inner side of the clamping portion is vertically provided with two clamping blocks 21 arranged in a figure eight pattern. The upper and lower ends of the clamping blocks 21 are horizontally engraved with anti-slip grooves. The piston rod of the clamping cylinder extends, driving the two rockers to swing outward, and the two clamping fingers enter a clamped state. The piston rod of the clamping cylinder drives the two rockers to swing inward, and the two clamping fingers enter an open state.
[0022] The inlay assembly 30 includes an inlay connecting plate 31, a first telescopic cylinder 32, a second telescopic cylinder 33, a first inlay gripper 34, and a second inlay gripper 35. One end of the inlay connecting plate 31 is vertically fixed to the rear end of the outer side surface of the right side plate of the connecting rod 1 by screws, and the other end extends horizontally forward in a direction parallel to the center line of the connecting rod 1 to connect to the first telescopic cylinder 32. In order to improve the connection strength, a reinforcing plate can be provided on the inner side surface of the right side plate of the connecting rod 1. The first telescopic cylinder 32 is vertically fixed to the outer side surface of the extended end of the inlay connecting plate, and the cylinder piston rod extends vertically upward to connect to the second telescopic cylinder 33. The cylinder body of the second telescopic cylinder 33 is horizontally fixed to the piston rod of the first telescopic cylinder 32 by screws, and its piston rod extends away from the connecting rod to connect to the first inlay gripper 34. The second inlay gripper 35 is mounted on the cylinder base of the second telescopic cylinder, facing away from the first inlay gripper 34.
[0023] The first and second mounting grippers 34, 35 have the same structure. For example, the first mounting gripper 34 comprises a chuck body and three movable jaws 341. Each movable jaw is connected to a gripping finger 342. The inner surfaces of the gripping fingers 342 are designed as anti-slip surfaces. Specifically, the anti-slip surfaces are formed by horizontally and vertically forming V-shaped grooves on the inner surfaces of the gripping fingers. The connection between the chuck body and the three movable jaws 341 is conventional, as described in detail in the three-jaw chuck.
[0024] The air pipes of the first telescopic cylinder 32 , the second telescopic cylinder 33 and the third telescopic cylinder are all connected to the air source via an air pipe quick-connect module.
[0025] When using this application:
[0026] The multifunctional die-casting removal robot gripper of the present application is fixedly mounted on the robot arm through the connecting rod 1. After the die-casting is completed, the robot arm drives the gripper of the present application into the die-casting machine, grabs the die-casting handle through the handle gripper 20, removes the die-casting, and transfers it to the cooling process;
[0027] After cooling is completed, the first inserting gripper 34 and the second inserting gripper 35 each take an insert, the first telescopic cylinder 32 extends, the first inserting gripper 34 and the second inserting gripper 35 enter the interior of the die-casting machine, the second telescopic cylinder 33 extends, the first inserting gripper 34 inserts the insert in one direction, and after the inserting is completed, the second telescopic cylinder 33 retracts, and the second inserting gripper 35 inserts the insert in the other direction;
[0028] After the inlay is completed, the die-cast product is grabbed by the first product gripper 11 and the second product gripper 12 and placed on the conveyor belt to be transported to the next process.
[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also within the scope of protection of the present invention.
