[0017] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model discloses a hand grasping mechanism capable of implanting multiple types of hardware and removing products, combined with Figures 1 to 4 As shown, it includes a plate body 1, on which a first copper sheet picking and placing mechanism 2, a second copper sheet picking and placing mechanism 3, a nut picking and placing mechanism 4 and a workpiece taking out mechanism 5 are provided, the first copper sheet picking and placing mechanism 2 is used to absorb the first special-shaped copper sheet 20, the second copper sheet picking and placing mechanism 3 is used to absorb the second special-shaped copper sheet 30, the nut picking and placing mechanism 4 is vertically arranged at the end of the plate body 1, and the nut picking and placing mechanism 4 is used to insert the copper nut 40, and the workpiece taking out mechanism 5 is used to clamp the workpiece 50 completed by injection molding.

[0019] In the above structure, the first copper sheet picking and placing mechanism 2, the second copper sheet picking and placing mechanism 3 and the workpiece taking out mechanism 5 are arranged on the same side of the plate body 1, and the nut picking and placing mechanism 4 is arranged at the end position of the plate body 1. Before embedding the hardware, the first special-shaped copper sheet 20 is first adsorbed on the first copper sheet picking and placing mechanism 2, the second special-shaped copper sheet 30 is adsorbed on the second copper sheet picking and placing mechanism 3, the copper nut 40 is set on the nut picking and placing mechanism 4, and then the plate body 1 is driven by a preset robot arm to move into the mold of the injection molding machine, and the first special-shaped copper sheet 20 and the second special-shaped copper sheet 30 are adsorbed on the second copper sheet picking and placing mechanism 3. 0 is placed at a preset copper sheet embedding position, and the copper nut 40 is placed at a preset nut embedding position, thereby realizing the embedding function of two special-shaped copper sheets and nuts. Compared with the prior art, the utility model does not need to use multiple mechanical grippers, and does not need to repeatedly enter the mold cavity, which not only improves the action efficiency but also saves the application cost. After the injection molding is completed, the workpiece removal mechanism 5 can also be used to clamp the injection molded workpiece 50 into the mold of the injection molding machine. The whole process can be realized by only one mechanical gripper, which effectively simplifies the control logic, saves system control resources, and better meets the application requirements.

[0020] See also Figure 4 In this embodiment, the first copper sheet picking and placing mechanism 2 includes a first adsorption fixture 21, and the first adsorption fixture 21 is provided with two first adsorption grooves 22. Two first special-shaped copper sheets 20 are arranged in the two first adsorption grooves 22. The bottom of the first adsorption groove 22 is provided with a first adsorption hole 23, and the side of the first adsorption fixture 21 is provided with a first negative pressure connecting air nozzle 24 connected to the first adsorption hole 23.

[0021] Furthermore, a first cylinder ejecting mechanism 25 for ejecting the two first special-shaped copper sheets 20 from the first adsorption groove 22 is provided on the back side of the plate body 1 .

[0022] In the above structure, the two first special-shaped copper sheets 20 are arranged in the two first adsorption grooves 22 after being crossed in an "X" shape. After the first negative pressure connecting nozzle 24 is connected to the negative pressure air source, negative pressure is generated in the first adsorption hole 23, so that the two first special-shaped copper sheets 20 are adsorbed in the two first adsorption grooves 22. When the robot arm carries the plate body 1 to a preset position in the mold cavity of the injection molding machine, the cylinder in the first cylinder ejection mechanism 25 can drive the ejector rod to eject the two first special-shaped copper sheets 20 in the two first adsorption grooves 22, so that the two first special-shaped copper sheets 20 are automatically buried in the preset position. Among them, this embodiment uses the method of negative pressure adsorption and cylinder ejection to cooperate with each other, which can not only ensure that the two first special-shaped copper sheets 20 are reliably placed in the two first adsorption grooves 22, but also use the cylinder to cooperate with the ejector rod to separate the two first special-shaped copper sheets 20 from the two first adsorption grooves 22. The picking and placing action of the special-shaped copper sheets is reliable, which can prevent the special-shaped copper sheets from falling out or falling during the transfer process, thereby improving the reliability of the action of embedding the copper sheets.

[0023] As a preferred embodiment, the second copper sheet picking and placing mechanism 3 includes a second adsorption fixture 31, two second adsorption grooves 32 are provided on the second adsorption fixture 31, two second special-shaped copper sheets 30 are arranged in the two second adsorption grooves 32, and the bottom of the second adsorption groove 32 is provided with a second adsorption hole 33, and the side of the second adsorption fixture 31 is provided with a second negative pressure connecting air nozzle 34 connected to the second adsorption hole 33.

[0024] Furthermore, a second cylinder ejection mechanism 35 for ejecting the two second special-shaped copper sheets 30 from the second adsorption groove 32 is provided on the back side of the plate body 1 .

[0025] The operating principle of the second copper sheet picking and placing mechanism 3 is the same as that of the first copper sheet picking and placing mechanism 2, and will not be described in detail here.

[0026] In this embodiment, see Figure 2 The nut picking and placing mechanism 4 includes a pin 41 for inserting the copper nut 40 and a cylinder push plate assembly 42 for pushing the copper nut 40 from the pin 41. In the above-mentioned nut picking and placing mechanism 4, the pin 41 can pass through the push plate in the cylinder push plate assembly 42. When the pin 41 is inserted into the copper nut 40 and moves to the designated embedding hole position, the cylinder in the cylinder push plate assembly 42 pushes the push plate, and then the push plate pushes the copper nut 40 from the pin 41, and then automatically embeds it in the designated hole position.

[0027] As a preferred method, see Figure 1 and Figure 3The workpiece taking-out mechanism 5 includes a pneumatic clamp 51 for clamping the workpiece 50. In this embodiment, after the workpiece is injected, the workpiece 50 can be directly taken out by the workpiece taking-out mechanism 5, without the need to set up a taking-out robot, thereby reducing the number of robot grips.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
