For example, the automatic plate sucking machine can adopt a PLC automatic control system, manual operation is not needed, and therefore labor force can be reduced. The manipulator is precisely driven by adopting a high-precision servo motor, and fittings such as an oil-free vacuum pump and a valve are adopted for the pipeline design of the vacuum chuck 10.

The control system sends a command to move the vacuum chuck 10 and robot to the top of the product positioning collection platform (first positioning position) and lower. The vacuum electromagnetic valve enables the vacuum energy accumulator to be communicated with the vacuum chuck 10 manipulator, the surface of the vacuum chuck 10 is vacuumized, and the metal composite plate is grabbed from the positioning collection platform.

Then, the vacuum chuck 10 and the robot drive the metal composite plate to move and descend above the product stacking platform (second positioning position). The vacuum solenoid valve shuts off the connection between the vacuum accumulator and the vacuum chuck 10, so that the metal composite plate falls onto the product stacking platform from the vacuum chuck 10. From this, realized snatching the working process to the product on stacking the platform with metal clad sheet from location collection platform with the manipulator, practiced thrift the cost of labor in a large number, improved work efficiency.

The guide mechanism is used for gradually limiting the four corners of the plate released from the second positioning position in the horizontal direction, so that the plate falls onto the stacking platform in a limited state.

Please refer to fig. 2. In a preferred embodiment, the stacking platform may be rectangular, and the guiding mechanism may include a position-limiting blocking groove vertically disposed at four corners of the rectangular stacking platform, and a guiding groove disposed at an upper end of the position-limiting blocking groove and forming a smooth transition with the upper end of the position-limiting blocking groove.

Further, each limit stop groove may include a first stop 20 for limiting the longitudinal horizontal movement of the sheet, and a second stop 23 for limiting the lateral horizontal movement of the sheet, and the first stop 20 and the second stop 23 meet at a right angle.

Further, the guide groove may include a first guide plate 21 having a smooth transition with the upper end of the first barrier 20 and extending outward and gradually expanding, and a second guide plate 22 having a smooth transition with the upper end of the second barrier 23 and extending outward and gradually expanding. That is, the width of the upper end of the first guide plate 21 is greater than the width of the lower end of the first guide plate 21, the width of the upper end of the second guide plate 22 is greater than the width of the lower end of the second guide plate 22, and the first guide plate 21 and the second guide plate 22 are connected with each other at the inner side to form a guide groove structure which gradually inclines outwards and expands from bottom to top.

Further, a guide wire 28 between the first guide 21 and the second guide 22 and a baffle wire 29 between the first baffle 20 and the second baffle 23 are smoothly connected to each other and are on the same coordinate plane. Thus, when the sheet is released to fall freely horizontally from the upper second positioning position, the four corners of the sheet may be correspondingly restrained in the upper ends of the guide grooves and limited by the longitudinal (x-axis) distance from the two pairs of first guide plates 21 at the front and rear ends and the lateral (y-axis) distance from the two pairs of second guide plates 22 at the left and right sides, respectively, and gradually guided to the guide plate wire 28 between the first guide plate 21 and the second guide plate 22 and slid down in a substantially horizontal state along the guide plate wire 28 between the first guide plate 21 and the second guide plate 22 and the baffle plate wire 29 between the first baffle plate 20 and the second baffle plate 23 by the appropriate elastic action of the first guide plate 21 and the second guide plate 22.

In a preferred embodiment, the limit stop groove and the guide groove can be made of metal materials.

Each guide groove and one corresponding limit stop groove are connected and arranged on one corner of the stacking platform in an independent state. Namely, any guide groove arranged on the stacking platform and the limit stop groove connected with the guide groove are not connected with any other structure.

Thus, the first guide plate 21 and the second guide plate 22 will have a certain elasticity due to the upper end being in a free state. And, the first shutter 20 and the second shutter 23 thus have a slight elastic swinging capability. In the process of falling of the plate, the first baffle 20 and the second baffle 23 are driven by the elastic action of the first guide plate 21 and the second guide plate 22 to generate certain vibration, so that the four corners of the plate when falling can automatically contract to cause errors, and when each plate falls to a product stacking platform at the lower end of the limiting blocking groove, the stacking effect which is even with the edges of other plates falling before is obtained.

In a preferred embodiment, the support structure may include feet 25 disposed on the lower ends of the four corners of the stacking platform.

In a preferred embodiment, the lower end of the arm brace 25 may be provided with an adjusting bolt.

In a preferred embodiment, brackets 26 may be further provided on the lower ends of the left and right sides of the frame 27.

When the whole pallet is transported by a forklift, the rectangular frame 27 with the suspended stacking platform can be smoothly forked through the space of the bracket 26.

In a preferred embodiment, the stacking platform is made of a metal material.

In a preferred embodiment, the method further comprises providing a lifting platform on which the landing gear is provided. When the stacking platform is forked or hoisted together with the sheet material onto the lifting platform and lowered, the landing gear on the lifting platform can pass out from under the grid-like support of the stacking platform of the frame structure, so that the sheet material is lifted from the stacking platform on which it is stacked and separated from the stacking platform. Therefore, the plate can be separated from the stacking platform for packing and hoisting, so that the stacking platform can be recycled.

In a preferred embodiment, the error between the length and width dimension of the rectangle surrounded by the inner peripheries of the four limit stop grooves and the dimension of the plate is controlled within the range of 0.5mm to +1.0 mm.

In a preferred embodiment, the error between the length and width of the rectangular frame 27 of the stacking platform and the dimension of the plate is controlled within the range of 0.0mm to +0.5 mm.

In a preferred embodiment, the arc length of the arc-shaped first guide plate 21 and the arc-shaped second guide plate 22 of the guide groove may be 20mm, and the angle extending outward may be 25 to 30 degrees.

When the vacuum electromagnetic valve is used for switching off the connection between the vacuum energy accumulator and the vacuum sucker 10, for example, when metal composite plate materials fall onto a product stacking platform from the vacuum sucker 10, the metal composite plate materials are influenced by the gravity of free falling bodies and are outwards designed by the arc of the guide groove, the position error between the metal composite plates generated by the automatic plate sucking machine during plate sucking and stacking at each time can be 1-3 mm, the metal composite plates can automatically shrink to the inner side of the limit stop groove along the arc of the guide groove, so that the placing regularity error between two adjacent metal composite plates can be controlled within 0.5mm, and the parallelism and verticality accumulated error of the whole plate supporting edge can be controlled within 1.0 mm. The whole supporting plate is orderly and flatly observed by eyes, and the requirement of a client on the subsequent automatic finish machining positioning error is completely met.
