[0030] ​In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0031] Embodiment one

[0032] With reference to Figures 1-3 A full-automatic plate stacking machine, comprising a rack 1 and a control panel 6, the rack 1 is provided with a conveying assembly 2, a suction unit 5 and a lifting platform, the rack 1 is provided with a material box 4 on the side close to the feeding end of the conveying assembly 2, the bottom of the material box 4 is provided with a vibrator, the vibrator cooperates with the material box 4 and can drag the wood board in the material box 4 to move close to the conveying assembly 2, this technology is similar to the existing vibrating disc technology and can be realized, and no further description is made.

[0033] The suction unit 5 is located above the discharging end of the conveying assembly 2, the height of the discharging end of the conveying assembly 2 is higher than that of the feeding end, the lifting platform is not shown in the figure, the height of the upper surface of the lifting platform is adjustable, the lifting platform is close to the discharging end of the conveying assembly 2, the lifting platform can be selected from the existing scissor type lifting platform technology, or a workbench is driven to rise or fall through a hydraulic rod, an electric telescopic rod and the like to form a lifting platform, and no further description is made.

[0034] The conveying assembly 2 is used for receiving the wood board and lifting the wood board to the lower side of the suction unit 5, the suction unit 5 adopts a negative pressure suction mode to suck the wood board, the rack 1 is provided with a traction assembly for driving the suction unit 5 to move between the discharging end of the conveying assembly 2 and the lifting platform, the traction assembly is a technology that can be realized by the prior art, and can adopt a technology similar to the existing 3D printer traction printing platform to move in a three-dimensional coordinate system, and no further description is made.

[0035] The working principle of the embodiment one is specifically shown as follows:

[0036] The worker drops the wood board into the material box 4, the length direction of the wood board is parallel to the width direction of the conveying assembly 2, through the cooperation of the material box 4 and the vibrator, the wood board is dragged close to the feeding end of the conveying assembly 2, the wood board is lifted to the lower side of the suction unit 5 through the conveying assembly 2, the suction unit 5 is pulled down through the traction assembly, and the negative pressure suction of the suction unit 5 to the wood board is realized.

[0037] Then, the lifting platform operates, so that the upper surface height of the wood board stacked on the lifting platform is consistent with the discharging end of the conveying assembly 2, then the suction unit 5 and the wood board are moved to the upper side of the lifting platform through the traction assembly, then the suction unit 5 is pulled down through the traction assembly, so that the suction wood board completes stacking, after that, the suction unit 5 cancels the suction, and the traction assembly resets the suction unit 5.

[0038] Each time the wood board is stacked, due to the setting of the lifting platform, the distance of the adsorption unit 5 can be greatly reduced, thereby reducing the time spent each time the wood board is stacked, and the cumulative reduction of time is more objective, which can effectively improve the stacking efficiency of the wood board.

[0039] When the wood board stacking on the lifting platform reaches the maximum value, a roller can be arranged at the bottom of the lifting platform, the lifting platform is manually pushed away, and the next empty lifting platform is pushed over, or the roller is driven to rotate by a hub motor to realize automatic movement.

[0040] Further, referring to Figure 2 With Figure 3 , the conveying assembly 2 adopts a synchronous belt technology or a chain technology, and the outer surface is vertically provided with a claw rod 3, and the claw rod 3 is arrayed in the conveying direction of the conveying assembly 2. A plurality of avoiding openings are arranged on the material box 4 for avoiding the claw rod 3.

[0041] The bottom of the material box 4 is inclined and the lowest point is close to the conveying assembly 2; in this way, when the conveying assembly 2 operates, the claw rod 3 at the discharging end moves from bottom to top, which can hook the wood board, thereby dragging the wood board to move together.

[0042] Embodiment two

[0043] Referring to Figures 4-9 , the adsorption unit 5 includes an upper frame 7 and a negative pressure source, the upper frame 7 is provided with an adsorption seat 9 through a connecting assembly 8, the inside of the adsorption seat 9 is hollow, the upper surface of the adsorption seat 9 is provided with a plurality of connecting openings 901, one hose 10 is connected to the upper opening of each connecting opening 901, the negative pressure source and the ends of the plurality of hoses 10 are connected through a connecting valve, the negative pressure source can adopt existing air compressor technology, or negative pressure pump technology, etc., which will not be described here, the lower surface of the adsorption seat 9 is provided with a plurality of sponge blocks 902, the bottom of the sponge block 902 is provided with a plurality of adsorption holes one, and the lower surface of the adsorption seat 9 is provided with adsorption holes two in communication with the adsorption holes one.

[0044] In use, the upper frame 7 is moved by traction, so that the sponge block 902 is attached to the wood board and downward pressure is applied to the sponge block 902, so that the sponge block 902 is tightly attached to the upper surface of the wood board. Then, the connecting valve is opened, the negative pressure source is started, and the wood board is firmly adsorbed on the sponge block 902 by the negative pressure adsorption principle. Then, the connecting valve is closed, and the negative pressure source is closed. Since the sponge block 902 is tightly attached to the wood board, a sealing fit is formed, so that the negative pressure adsorption of the wood board can be maintained. Then, the wood board is transferred to the preset position, the connecting valve is opened, the negative pressure environment of the adsorption seat 9 disappears, and the adsorption of the wood board is cancelled. In this way, the negative pressure source does not need to be continuously opened during the transfer of the wood board, which greatly reduces energy consumption. It should be noted that the core of the second embodiment is the improvement of the adsorption structure of the wood board. How to transfer the wood board to the preset position is realized by the prior art, such as a mechanical arm, and is not described in detail.

[0045] Further, referring to Figure 4 During the transfer of the wood board, the upper frame 7 needs to be rotated sometimes. Therefore, the distance between the rotation axis of the upper frame 7 and each connecting port 901 is consistent. The significance of this is that during the rotation of the upper frame 7, this method can make the rotation radius of all the hoses 10 consistent, and can reduce the probability of entanglement and knotting between adjacent hoses 10 as much as possible.

[0046] Further, referring to Figure 6 The connecting assembly 8 includes a connecting seat 801 connected to the upper frame 7 by bolts. A sliding hole with a vertical axis is provided through the connecting seat 801. A sliding rod 802 is sleeved in the sliding hole. The upper and lower ends of the sliding rod 802 protrude out of the sliding hole. The upper end of the sliding rod 802 is provided with a limiting ring 803, and the lower end of the sliding rod 802 is provided with a base 804. The base 804 is fixed to the adsorption seat 9. A spring 805 is sleeved outside the sliding rod 802 between the base 804 and the connecting seat 801. In addition, a sensor for detecting the spring force of the spring 805 is arranged on the connecting seat 801. The sensor can be a pressure sensor to directly detect the spring force, or a distance sensor to calculate the spring force by detecting the compression amount. The details are not described herein. The significance of this is that after the sponge block 902 contacts the wood board, the upper frame 7 continues to move downward, so that downward pressure is applied to the sponge block 902, and the sponge block 902 is tightly attached to the upper surface of the wood board. During this process, the spring 805 is compressed, and the spring force is the pressure applied to the sponge block 902. Therefore, the pressure can be monitored by the sensor until it reaches a preset value, and then the connecting valve can be closed. That is, after the sponge block 902 is tightly attached to the wood board to form a sealing fit, the connecting valve is closed.

[0047] Further, referring to Figure 9The connecting valve comprises a valve shell 11, one end of which is open, the other end of which is closed and internally sleeved with a shutter 14, the shutter 14 is driven by a telescopic rod 15 arranged on the outer surface of the valve shell 11 and can move in the valve shell 11, the upper surface of the valve shell 11 is provided with an upper hole, the lower surface of the valve shell 11 is provided with a lower hole, the upper hole and the lower hole are located on the same vertical line, an upper connecting nozzle 12 extends at the hole of the upper hole, the upper connecting nozzle 12 is connected with a negative pressure source through a pipeline, a lower connecting nozzle 13 extends at the hole of the lower hole, and the lower connecting nozzle 13 is connected with the hose 10; the telescopic rod 15 can be selected from existing electric telescopic rods or hydraulic rods and the like, and will not be described herein, the shutter 14 is driven to move by the telescopic rod 15, so that the upper hole and the lower hole are communicated or the communication is cancelled, so that the connecting valve is opened or closed.

[0048] In a preferred embodiment (not shown in the drawings), the inner cavity of the adsorption seat 9 is divided into two parts which are not communicated with each other and are respectively a negative pressure cavity and a cleaning cavity, the adsorption hole two is communicated with the negative pressure cavity, the sponge block 902 is arrayed with cleaning holes which are communicated with the cleaning cavity, the outer surface of the adsorption seat 9 is connected with a cleaning pipe which is communicated with the cleaning cavity, and the end of the cleaning pipe is connected with a blower, so that the action of adsorbing the wood board can be suspended periodically, then the blower is started to suck the air in the cleaning cavity, so that the cleaning holes are in a negative pressure state, and the dust and wood chips on the lower surface of the sponge block 902 are sucked away, that is, the sponge block 902 is cleaned, so that the negative pressure adsorption performance of the sponge block 902 is not affected by the dust and wood chips, and further, the cleaning holes and the adsorption hole one can be arranged alternately and close to each other to improve the cleaning effect.

[0049] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed in the above preferred embodiment, it is not intended to limit the present application.
