Description

Technical Field

[0001] The utility model relates to the technical field of CCD integrated detection machines, in particular to a multi-fan partition independently driven negative pressure adsorption structure. Background Art

[0002] The negative pressure adsorption structure is the core component used for negative pressure adsorption and transmission in the CCD all-in-one detection machine. The existing negative pressure adsorption structure still has shortcomings, specifically: the existing negative pressure adsorption structure is driven by a single fan. In the initial stage of single fan drive, most of the negative pressure cavity holes in the cavity are not blocked and it is difficult to generate negative pressure. When the product covers all the holes in the negative pressure cavity, the negative pressure will reach the maximum negative pressure of the negative pressure fan. The negative pressure fluctuates greatly during the entire operation process. If the negative pressure is too small, the product cannot be sucked up or cannot be sucked up well, resulting in falling and damage. If the negative pressure is too large, the friction will increase, which can easily cause problems such as overload of the transmission motor, belt slippage, broken shaft, worn shaft, and deviation of the transmission belt.

[0003] Therefore, a multi-fan partition independently driven negative pressure adsorption structure is needed to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-fan partition independently driven negative pressure adsorption structure to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-fan zone independently driven negative pressure adsorption structure comprises an adsorption cavity, a negative pressure mechanism is arranged inside the adsorption cavity, a cover plate is fixedly connected to the top of the adsorption cavity, a terminal is installed on the outer wall of the adsorption cavity, and a controller is installed on the outer wall of the adsorption cavity near the terminal;

[0007] The negative pressure mechanism includes a transverse partition fixedly connected to the inner wall of the adsorption chamber, the outer wall of the transverse partition is fixedly connected to the longitudinal partition in the adsorption chamber, an adsorption box is fixedly connected to the interior of the negative pressure mechanism and at a position close to the transverse partition, an exhaust pipe is fixedly connected to the interior of the adsorption box, a guide pipe is fixedly connected to the top of the exhaust pipe, an air outlet duct is fixedly connected to the outer wall of the guide pipe and at an end away from the adsorption box, a guide groove is provided inside the adsorption box, a negative pressure fan is fixedly connected to the outer wall of the adsorption chamber at a corresponding position of the air outlet duct, and a through groove is provided at the bottom of the inner wall of the adsorption chamber.

[0008] As a preferred solution of the utility model, the adsorption chamber and the cover plate are both made of stainless steel, and the connection between the terminal and the controller is an electrical connection.

[0009] As a preferred solution of the utility model, the transverse partition, the longitudinal partition and the adsorption box are all made of stainless steel, and the longitudinal partition is connected to the adsorption cavity in a fixed manner.

[0010] As a preferred solution of the utility model, the transverse partition, the longitudinal partition, the adsorption box, the air outlet duct and the negative pressure fan are all provided in multiple groups, and the adsorption box and the air outlet duct penetrate and extend to the outside of the longitudinal partition.

[0011] As a preferred solution of the utility model, the negative pressure fan passes through the adsorption cavity and extends into the air outlet duct, and the guide pipe passes through the adsorption box and extends into the air outlet duct.

[0012] As a preferred solution of the utility model, the through slot is designed as a rectangular structure, and the connection method between the negative pressure fan and the controller is an electrically uniform connection.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a multi-fan partition independently driven negative pressure adsorption structure is designed, and the negative pressure mechanism in the device is used to adsorb products. The controller starts the negative pressure fan, and the negative pressure fan discharges the air in the negative pressure cavity through the air outlet duct, the guide pipe and the exhaust pipe. The external air also flows into the negative pressure cavity through the through groove on the lower surface of the negative pressure cavity. When the inflowing air flow rate is less than the exhausting air flow rate, a pressure difference will be generated between the inside and outside of the negative pressure cavity. When the pressure difference acts on both sides of the product, an adsorption force is generated. The longitudinal partition and the transverse partition divide the traditional negative pressure cavity into multiple independent areas along the product running direction. Each area is driven by a separate negative pressure fan, and different areas can be adjusted according to the product output. The functions in the conveying process are different, and different frequency parameters are selected to set. The negative pressure of the product during the conveying process can be made approximately constant, and the negative pressure is always the set negative pressure of the negative pressure fan in the independent area. The existing negative pressure adsorption structure is driven by a single fan. In the initial stage of single fan drive, most of the negative pressure cavity holes in the cavity are not blocked and it is difficult to generate negative pressure. When the product covers all the holes in the negative pressure cavity, the negative pressure will reach the maximum negative pressure of the negative pressure fan. The negative pressure fluctuates greatly during the entire operation. If the negative pressure is too small, the product cannot be sucked up or sucked well, resulting in falling and damage. If the negative pressure is too large, the friction is increased, which can easily cause problems such as conveying motor overload, belt slippage, shaft breakage, shaft grinding, and conveyor belt deviation.
