Detailed Description

The present invention will be described in more detail with reference to the accompanying drawings and examples.

The utility model discloses a two-stage door transmission device for a dust-free chamber channel, which is shown in figure 1 and comprises a transition chamber 1, a dust-free chamber 2 and a transmission mechanism, the transition chamber 1 is provided with a first door 3, the transition chamber 1 is isolated from the outside by the first door 3, a second door 4 is arranged between the transition chamber 1 and the dust-free chamber 2, the conveying mechanism extends from the dust-free chamber 2 to the outside, the conveying mechanism penetrates through the first door 3 and the second door 4, a material vehicle is arranged on the conveying mechanism, and the conveying mechanism drives the material vehicle to convey between the outside and the transition chamber 1 and the dust-free chamber 2, when the material trolley enters and exits between the transition chamber 1 and the outside, the first door 3 is opened and the second door 4 is closed, when the material trolley enters and exits between the transition chamber 1 and the dust-free chamber 2, the second door 4 is opened, and the first door 3 is closed.

Among the above-mentioned device, having adopted the two-stage door to keep apart, the material car is by external at first getting into transition room 1, reach clean level after, automatic conveying again to in the dust free chamber 2, has improved dust free chamber and external isolation greatly, has effectively reduced the pollution of material to dust free chamber 2, the utility model discloses realizing the material car and being in when dust free chamber 2 comes and goes between the external world, corresponding clean level has been kept to solved loaded down with trivial details, take the manual work of material business turn over dust free chamber in-process, easily polluted the scheduling problem, satisfied the application demand betterly.

For the concrete process of the material cart entering and exiting the clean room 2, see the following embodiments: the operation steps can be divided into two steps, firstly, materials are transmitted to a dust-free room from the outside: the method comprises the steps that an external input request → a trolley starts to prepare to move to the outside from a transition chamber, stops when reaching a position of a specified first door, waits for the first door to be opened, moves to an external loading position → loading is completed, confirms a transmission command instruction → opens the first door again → automatically closes the first door when entering the transition chamber, works by an air shower device, meets a clean condition, detects that the clean condition reaches → opens a second door, enters a dust-free chamber and completes a feeding action;

secondly, the materials are conveyed to the outside from the dust-free chamber: inputting a request from a transition chamber → moving the trolley to the dust-free chamber from the transition chamber, stopping when the trolley reaches a position of a designated second door, detecting a clean condition, requiring the system to open the second door → the second door is opened completely, then reaching a feeding and discharging position in the dust-free chamber → finishing feeding, confirming a transmission command instruction → opening the second door when the second door is determined to be allowed to be opened again, transmitting the second door to the transition section, moving to a first door opening and closing position → opening the first door, then transmitting the material to an external feeding and discharging position, and semi-closing the first door.

In a preferred embodiment, the transition chamber 1 is connected to a cleaning device 5 for cleaning the air inside the transition chamber 1. Wherein, purifier 5 adopts multistage purification, reaches clean state fast, and strong wind drenches the system operation back, and the ion fan is strengthened assisting and is taken out, and high accuracy particle detecting instrument realizes automatic control through automatic identification, and the system control is integrative to be accomplished.

As for the specific structure of the conveying mechanism, as shown in fig. 1 and 2, the conveying mechanism includes a rail 6, a rail driving wheel 7 is disposed at the bottom of the material car, the rail driving wheel 7 is clamped on the rail 6, and the material car is driven to move along the rail 6 by controlling the operation of the rail driving wheel 7. In the structure, the ground rail type transmission system is adopted, the rail of the transfer trolley is set to be in a ground rail type, the rail is embedded on the ground, only gaps are reserved at wheel openings and are close to a seamless state, the probability of pollution caused by the outside and the public part of a dust-free room is reduced to a greater extent, and in addition, the structure is simple and easy to realize.

As a preferable mode, the present embodiment further includes an external controller 8 located outside and an indoor controller 9 located in the clean room 2, where the external controller 8 and the indoor controller 9 are both used to control the first door 3 and the second door 4 to perform opening and closing actions and to control the material cart to move back and forth along the track 6.

The automatic transmission function is arranged in the embodiment, and the trolley can automatically respond to the call and move to a designated position by utilizing the local calling action of the controller when the function is required to be transmitted no matter the trolley is located outside a dust-free room or in the dust-free room. For example: when the outside need convey the material and get into the clean room, externally press the request demand button of external control ware, dolly automatic positioning to demand position, with material automatic transmission to the clean room in, when the clean room material need be transmitted out in the same reason, also only need a key request can accomplish automatic demand, whole automatic completion need not personnel's intervention, and the automated performance is higher.

The above is only the embodiment of the present invention, and is not intended to limit the present invention, and all modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included within the protection scope of the present invention.
