[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] Example 1

[0035] like Figures 1 to 3As shown, the present device for grasping plate products comprises a mounting plate 1, the top surface of which serves as the assembly surface, and the bottom surface of which serves as the clamping surface. The mounting plate 1 is provided with a plurality of positioning drive mechanisms. The mounting plate 1 has a plurality of positioning openings formed therein. The positioning drive mechanisms comprise positioning cylinders 2 fixed to the assembly surface. Positioning cylinders 2 extend and retract to drive positioning pins 3, which extend through corresponding positioning openings and out of the clamping surface. Guide sleeves 4 are provided on the clamping surface corresponding to the positioning openings, and the positioning pins 3 are inserted into the corresponding guide sleeves 4, allowing for free extension and retraction.

[0036] There are several positioning holes on the cylinder head, and positioning pins 3 are extended through several positioning cylinders 2. Several positioning pins 3 extend from guide sleeves 4 and penetrate into the several positioning holes of the cylinder head one by one, so as to accurately position the cylinder head in the horizontal direction.

[0037] like Figures 1 to 3 As shown, preferably, at least two cylinder head clamping mechanisms are arranged opposite to each other on the two X sides of the mounting plate 1, and the cylinder head clamping mechanism includes a cylinder head clamping cylinder 5 fixedly mounted on the assembly surface, and the cylinder head clamping cylinder 5 has a telescopic shaft extending out of the clamping operation surface, and the telescopic shaft is connected to a multi-rod clamping claw 6; Figure 4 As shown, the multi-rod clamp 6 includes a base 6a fixed on the clamping operation surface, the top of the first rod 6b is hinged on the base 6a, the top of the second rod 6c and the top of the third rod 6d are hinged on the telescopic shaft respectively, the bottom end of the second rod 6c is hinged to the middle of the first rod 6b, the bottom end of the third rod 6d is hinged to the outer end of the fourth rod 6e, the bottom end of the first rod 6b is hinged to the middle of the fourth rod 6e, and the inner end of the fourth rod 6e has a claw hook.

[0038] When the telescopic shaft moves upward, it drives the top ends of the second and third rods 6c and 6d upward, which in turn pulls the bottom end of the first rod 6b upward and the outer end of the fourth rod 6e upward, causing the claw hook to move away from the clamping surface and release the cylinder cover. When the telescopic shaft moves downward, it drives the top ends of the second and third rods 6c and 6d downward, which in turn pushes the bottom end of the first rod 6b downward and the outer end of the fourth rod 6e downward, causing the claw hook to engage the clamping surface. The claw hook then extends into the corresponding inlet and outlet holes of the cylinder cover and presses tightly to hook the cylinder cover.

[0039] like Figures 1 to 3 As shown, preferably, a pallet clamping mechanism is disposed oppositely on the two Y edges of the mounting plate 1. The pallet clamping mechanism includes a sliding assembly, which includes an X-direction guide rail 7 fixed to the assembly surface. A slider 8 is slidably engaged on the X-direction guide rail 7, and a slide 9 is fixedly connected to the slider 8. There are two X-direction guide rails 7 and they are symmetrically arranged. A slider 8 is correspondingly disposed on each X-direction guide rail 7, and the two sliders 8 are connected to a slide 9.

[0040] Preferably, the pallet clamping cylinder 10 is fixed to the slide 9 and includes a telescopic rod extending parallel to the mounting surface. The telescopic rod is connected to the mounting surface, and the pallet clamping cylinder 10 is provided with a pallet clamping claw 11 extending outward from the clamping operation surface. When the pallet clamping cylinder 10 drives the telescopic rod to extend and retract, the pallet clamping cylinder 10 and the slide 9 slide back and forth in the X direction, driving the pallet clamping claws 11 on both sides of the Y side to expand or converge, thereby grasping or releasing the pallet.

[0041] Preferably, the two Y sides of the mounting plate 1 are symmetrically recessed with notches, and the pallet clamp 11 is arranged in the notches. The pallet clamp 11 includes a vertical plate, the top of the vertical plate is fixedly connected to the slide plate 9, the vertical plate passes through the notch downward, and the bottom end of the vertical plate is provided with a claw head with the claw mouth facing outward.

[0042] A notch is located between the two X-axis guide rails 7, and the inner edge of the notch defines the maximum inward translation range of the pallet clamping jaws 11. The pallet clamping cylinders 10 on both sides simultaneously retract their telescopic rods, bringing the pallet clamping jaws 11 together so that the claws are positioned inside the pallet. The pallet clamping cylinders 10 then simultaneously extend their telescopic rods, expanding the pallet clamping jaws 11 so that the two opposing claws grip the pallet from the inside for gripping. The pallet clamping cylinders 10 again simultaneously retract their telescopic rods, bringing the pallet clamping jaws 11 together, releasing the pallet.

[0043] like Figure 2 and 3 As shown, preferably, a support is fixed to the assembly surface, and the end of the telescopic rod is connected to the support via a floating joint 12. The floating joint 12 is a universal component with various structures. It is commonly used at the connection between cylinders, linear modules and driven mechanisms. Its function is to eliminate installation or processing errors between the driving mechanism and the driven mechanism, preventing problems such as drive problems and creeping.

[0044] like Figure 1 and 3 As shown, preferably, a bracket 1 is fixed to the clamping operation surface of the mounting plate 1, and a proximity switch 13 is mounted on the bracket 1, with the sensing probe of the proximity switch 13 facing downward. The function of the proximity switch 13 is to determine whether the cylinder head is flush with the cylinder head positioning surface by detecting two points on the cylinder head, thereby ensuring consistency in the grasping and placement posture.

[0045] like Figures 1 to 3 As shown, preferably, a calibration axis 14 is provided along the X direction on one Y side of the mounting plate 1. The calibration axis 14 and the mounting plate 1 are located in the same plane, and a protective cap is sleeved on the outer end of the calibration axis 14. The function of the calibration axis 14 is to calibrate the coordinate system of the fixture relative to the robot itself, so as to quantitatively adjust the posture of the fixture.

[0046] like Figures 1 to 3As shown, preferably, a second bracket is fixed on the assembly surface of the mounting plate 1 , and a hard limiter 15 is provided on the second bracket along the X direction, with the limiting end of the hard limiter 15 exceeding the Y side.

[0047] Example 2

[0048] Based on the first embodiment, the difference of this embodiment is that:

[0049] A transfer device includes a robot with a mechanical arm and the above-mentioned plate product grasping device. A shaft sleeve is set in the middle of the assembly surface of the mounting plate 1, and the driving shaft of the mechanical arm is connected to the shaft sleeve to form a fixed installation.

[0050] The operation process of this transfer equipment is:

[0051] The robot's robotic arm drives the gripping mechanism to the grasping position. First, positioning cylinder 2 extends the corresponding positioning pin 3, depending on the cylinder head model. The robotic arm drives the positioning pin 3 into the corresponding positioning hole in the cylinder head, precisely positioning the cylinder head horizontally. The cylinder head clamping cylinder 5 drives the claws of the multi-rod gripper 6 to insert into the corresponding inlet and exhaust holes in the cylinder head and press them firmly. Proximity switch 13 detects that the cylinder head is grasped in place. The robot then moves the gripping mechanism and cylinder head to the placement position. The cylinder head clamping cylinder 5 drives the claws of the multi-rod gripper 6 to release the cylinder head, completing the placement.

[0052] When all the cylinder covers on the pallet are removed, the pallet clamping cylinders 10 on both sides are started synchronously to extend the telescopic rods, so that the pallet claws 11 on both sides are expanded, so that the two relative claws support the pallet from the inside for grabbing. The robot drives the grabbing device and the pallet to move above the pallet offline conveyor line, and the pallet clamping cylinders 10 on both sides are started synchronously to retract the telescopic rods, so that the pallet claws 11 on both sides are gathered together, so that the claws release the pallet to the conveyor line.
