[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 and 2 As shown, the embodiment of the present invention provides an automatic palletizing device for automatically packaging silicon wafers, comprising:

[0031] The lifting plate 10 has cylinders 20 and guide rails symmetrically arranged on its left and right ends from the middle to the ends. A slider is slidably connected to the guide rail along the length of the lifting plate 10. A sliding plate 30 is horizontally mounted on the slider perpendicular to its sliding direction. The sliding plate 30 is connected to the push rod end of the cylinder 20.

[0032] The servo motor 40 is connected to the lead screw 41 and controls the movement of the lead screw 41. The lead screw 41 is vertically connected to the lifting plate 10.

[0033] The sliding plate 30 includes a first sliding plate 301 and a second sliding plate 302 symmetrical to each other. Horizontally placed forks 31 are symmetrically provided on the first sliding plate 301 and the second sliding plate 302 .

[0034] Specifically, the lead screw 41 is a trapezoidal lead screw, which has good wear resistance and smooth movement effect, so that the lifting plate 10 can be lifted and lowered smoothly.

[0035] In addition, in order to ensure that the forks 31 can pick up the pallet smoothly, there are two forks 31 on the first sliding plate 301 and the second sliding plate 302, that is, a total of four forks 31 are used to lift the pallet. The forks 31 are evenly stressed to ensure stability after picking up the pallet.

[0036] When in use, the push rod of the cylinder 20 is used to push and retract the sliding plate 30, so that the sliding plate 30 drives the fork 31 to loosen and clamp, thereby realizing the loosening and forking of the pallet, and then the servo motor 40 controls the movement of the lead screw 41, which drives the lifting plate 10 to rise or fall, thereby causing the fork 31 on the sliding plate 30 to rise or fall, thereby realizing the lifting and lowering of the pallet. The device has a simple structure and is easy to operate, avoiding the waste of manpower caused by manual stacking.

[0037] In order to improve automation, sensors are further included. The sensors are symmetrically arranged on the ground below the first sliding plate 301 and the second sliding plate 302 .

[0038] Since the servo motor 40 rotates at a high speed, a reducer 42 is installed between the servo motor 40 and the lead screw 41 to reduce the output speed of the servo motor 40 and increase the torque. In this embodiment, the speed of the servo motor 40 is 1500 revolutions per minute.

[0039] Furthermore, it also includes a protective net 50 and a support rod 60; the protective net 50 is in an enclosed shape with an open side and is located outside the lifting plate 10 and the slide 30; the support rod 60 includes a first support rod 601, a second support rod 602, a third support rod 603 and a fourth support rod 604, and the first support rod 601 and the second support rod 602 are placed vertically on the ground, supporting the third support rod 603, the fourth support rod 604, the lifting plate 10 and the components on the plate, and the third support rod 603 and the fourth support rod 604 are both vertically connected to the first support rod 601 and the second support rod 602; wherein the reducer 42 is arranged at the lower end of the servo motor 40 and fixed on the third support rod 603; the screw 41 passes through the third support rod 603 and the fourth support rod 604, and a coupling 43 is provided on the screw 41, and a bearing is provided at the lower end of the coupling 43, and the bearing is fixed on the fourth support rod 604.

[0040] like Figure 3 As shown, the present invention also provides an automatic palletizing system for pallets for automatic packaging of silicon crystal bars, comprising the automatic palletizing device for pallets for automatic packaging of silicon crystal bars as described above, and further comprising a host computer 70, a pallet buffer 80 and an AGV trolley 90 for pallet transportation;

[0041] in,

[0042] The pallet buffer 80 is connected to the automatic palletizing device for automatically packaging silicon wafer square bars through an AGV trolley 90;

[0043] The pallet buffer position 80 is provided with a first centering cylinder and an in-position sensor;

[0044] The host computer 70 is connected to the AGV 90, the servo motor 40, the cylinder 20 and the position sensor.

[0045] When the AGV trolley 90 delivers the pallet to the device and places it on the ground, the sensor senses it and the upper computer 70 controls the cylinder 20 and the servo motor 40 to start, and uses the fork 31 to lift the pallet on the ground. When the AGV trolley 90 delivers the next pallet to the device, the fork 31 descends and puts down the pallet, so that the pallets are stacked together. The fork 31 lifts the ground and the pallets above it together, and the cycle continues until the number of pallets preset in the upper computer is stacked. The upper computer 70 calls the AGV trolley 90 to transport the stacked pallets to the pallet buffer position 80 for automatic packaging. The device and system realize automatic pallet stacking of pallets, avoid waste of manpower, and improve the operating efficiency of automatic packaging.

[0046] It should be noted that when the AGV 90 only needs to take away one pallet, if there are multiple pallets in the device, the upper computer 70 controls the start cylinder 20 and the servo motor 40 to move the fork 31 to the second-layer pallet position, and lifts the pallets on the second layer and above together, so that the AGV 90 can take away the remaining pallet on the ground; if there is only one pallet in the device, the AGV 90 can take it away directly.

[0047] In order to prevent deviation when the AGV trolley 90 delivers or takes away the pallet, resulting in position deviation or unstable forking after the pallet is put down, the automatic stacking device for the pallet for automatic packaging of silicon crystal square rods also includes a second centering cylinder, which is located on the ground between the first sliding plate 301 and the second sliding plate 302; when the AGV trolley 90 delivers or takes away the pallet, it is necessary to first use the second centering cylinder to identify the position.

[0048] It should be noted that the AGV trolley 90 is a commercially available product and is not limited to any particular model, as long as its working functions are achieved.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
