DETAILED DESCRIPTION

[0023] To further illustrate the technical means and effects adopted by the present application to achieve the predetermined application purposes, the specific embodiments, structures, features and effects according to the present application will be described in detail below in combination with the drawings and preferred embodiments.

[0024] Reference Figures 1-6 The adsorption device of the automatic stacking machine comprises an upper frame 1 and a negative pressure source, the upper frame 1 is provided with an adsorption seat 3 through a connecting assembly 2, the adsorption seat 3 is hollow inside, the upper surface of the adsorption seat 3 is provided with a plurality of connecting ports 301, one hose 4 is connected to each connecting port 301, the negative pressure source is connected to the ends of the plurality of hoses 4 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 herein, the lower surface of the adsorption seat 3 is provided with a plurality of sponge blocks 302, a plurality of adsorption holes one are provided through the bottom of the sponge blocks 302, and the lower surface of the adsorption seat 3 is provided with adsorption holes two which are communicated with the adsorption holes one.

[0025] In use, the upper frame 1 is moved by traction, so that the sponge block 302 is attached to the wood board and downward pressure is applied to the sponge block 302, so that the sponge block 302 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 302 by the negative pressure adsorption principle. Then, the connecting valve is closed, and the negative pressure source is closed. Since the sponge block 302 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 pulled and transferred to the preset position, the connecting valve is opened, the negative pressure environment of the adsorption seat 3 disappears, and the adsorption of the wood board is cancelled. This way does not need to continuously keep the negative pressure source open during the wood board transfer process, greatly reducing the energy consumption. It should be noted that the core of the present scheme is the improvement of the adsorption structure of the wood board. How to pull the wood board to the preset position is realized by the prior art, such as a mechanical arm, and the like, which will not be described here.

[0026] Further, referring to Figure 1 During the wood board transfer process, the upper frame 1 needs to be rotated sometimes. Therefore, the distance between the rotation axis of the upper frame 1 and each connecting port 301 is consistent. The significance of this is that during the rotation of the upper frame 1, this way can make the rotation radius of all hoses 4 consistent, and can reduce the probability of entanglement and knotting between adjacent hoses 4 as much as possible.

[0027] Further, referring to Figure 3 The connecting assembly 2 includes a connecting seat 201 connected to the upper frame 1 by bolts. A sliding hole with a vertical axis is provided through the connecting seat 201. A sliding rod 202 is sleeved in the sliding hole. The upper and lower ends of the sliding rod 202 extend out of the sliding hole. The upper end of the sliding rod 202 is provided with a limiting ring 203. The lower end of the sliding rod 202 is provided with a base 204. The base 204 is fixed with the adsorption seat 3. The outside of the sliding rod 202 is sleeved with a spring 205 between the base 204 and the connecting seat 201. In addition, the connecting seat 201 is also provided with a sensor for detecting the spring force of the spring 205. The sensor can be an existing pressure sensor for directly detecting the spring force, or an existing distance sensor for calculating the spring force by detecting the compression amount. The details will not be described here. The significance of this is that after the sponge block 302 contacts the wood board, the upper frame 1 continues to move downward, thereby applying downward pressure to the sponge block 302, so that the sponge block 302 is tightly attached to the upper surface of the wood board. During this process, the spring 205 is compressed and the spring force is the pressure applied to the sponge block 302. Therefore, the pressure can be monitored by the sensor until it reaches the preset value, and then the connecting valve can be closed. That is, after the sponge block 302 is tightly attached to the wood board to form a sealing fit, the connecting valve is closed.

[0028] Further, referring to Figure 6The connecting valve comprises a valve shell 5, one end of the valve shell 5 is open, one end of the valve shell 5 is closed and the valve shell 5 is internally sleeved with a shutter 8, the shutter 8 is driven by an extension rod 9 arranged on the outer surface of the valve shell 5 and can move in the valve shell 5, an upper hole is arranged on the upper surface of the valve shell 5, a lower hole is arranged on the lower surface of the valve shell 5, the upper hole and the lower hole are located on the same vertical line, an upper connecting nozzle 6 extends at the hole opening of the upper hole, the upper connecting nozzle 6 is connected with a negative pressure source through a pipeline, a lower connecting nozzle 7 extends at the hole opening of the lower hole, and the lower connecting nozzle 7 is connected with the hose 4; the extension rod 9 can be an existing electric extension rod or a hydraulic rod technology, and details are not described herein, the shutter 8 is driven to move by the extension rod 9, 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.

[0029] In the preferred embodiment, the inner cavity of the suction seat 3 is divided into two parts which are not communicated with each other and are respectively a negative pressure cavity and a cleaning cavity, the suction hole two is communicated with the negative pressure cavity, the sponge block 302 is arrayed with cleaning holes which are communicated with the cleaning cavity, the outer surface of the suction seat 3 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 suction of the wood board can be paused 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 302 are sucked away, that is, the sponge block 302 is cleaned, so that the negative pressure suction performance of the sponge block 302 is not affected by the dust and wood chips, and further, the cleaning holes and the suction hole one can be arranged alternately and close to each other to improve the cleaning effect.

[0030] 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 preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, but as long as the changes do not deviate from the technical solution of the present application, any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are still within the scope of the technical solution of the present application.
