Workpiece monitoring system 7 contains door sensor 700 that opens and shuts, rack sensor 710, workpiece position sensor 720, workpiece switch module sensor 730, buffering door sensor 740.

The door opening and closing sensor 700 can detect the state of the door 201, when the door 201 is opened, the power control system 4 stops the movement of the workpiece in the buffer area, and the work area is not affected. Prevent that the staff from stretching into it when buffer area work, produce danger.

The placing rack sensor 710 can detect the placing state of the placing rack, and if the placing rack is not installed or the placing rack is placed wrongly, the system can not continue to work even if the staff press the starting button. Can effectively prevent the danger caused by neglected loading and wrong loading.

The workpiece position sensor 720 is a proximity sensor. The position of a workpiece on the placing frame can be detected. When the sensor corresponding to the rack for the workpiece to be coated detects the workpiece, the clamping jaws 222 pick up the workpiece and feed the workpiece into the clamping heads 303 of the working area. When the sensor corresponding to the rack for recovering the workpiece is not detected, that is, when no workpiece is on the rack, the clamping jaw 222 can enter the working area, and the workpiece with the film covering completed is clamped and taken back to the rack. In the process, the workpiece switching module sensor 730 detects the station where the placing rack is located, and the positions of the 2 placing racks are correspondingly switched, so that the circular operation is realized.

The buffer door sensor 740 can detect the open/close state of the buffer door 203, and is opened only when a workpiece needs to pass through.

In use, the workpiece 8 is loaded into one of the racks 204 outside the apparatus; opening the opening and closing door 201, wherein the opening and closing door sensor 700 detects that the opening and closing door is opened, and the power control system 4 stops all movements of the buffer area; two racks 204 (one with work pieces 8 and one empty) are placed together on a buffer stage 209. At this time, the rack sensor 710 can detect the state of the rack. After the opening and closing door 201 is closed and the button 502 is pressed, the equipment starts to automatically cover the mold.

The workpiece position sensor 720 will first detect the position of the workpiece on the placement frame. And if the conditions are met, the placing frame to be coated with the film is moved to the working position by the workpiece switching die. At this time, the clamping jaw 222 moves in the X-axis direction and clamps the workpiece. And carries the workpiece to move towards the working area. At the same time, the XZ-axis module 313 moves toward the slow door. When both 2 approach the buffer door, the buffer door 203 is opened so that the jaws 222 can feed the workpiece into the chucks 303 in the work area.

The jaws 222 then retract back into the buffer zone and the buffer door closes. At this time, the atmosphere monitoring system 6 monitors the atmosphere inside the working area, and if the atmosphere is within the set value range, the XZ axis module 313 moves in the direction of the X axis away from the buffer door to transport the workpiece to the specified position of the coating film. Then, the XZ axis module 313 is lowered at a set variable speed. When the height of the membrane liquid box cover 305 is lowered to a designated height, the membrane liquid box cover 305 can be automatically opened. The workpiece continues to descend, the electrodes enter the membrane liquid of the membrane liquid box 304, and after a period of time, the XZ axis module 313 ascends at a set variable speed. And conveys the workpiece to the damper door attachment.

At this time, the workpiece position sensor 720 will detect the position of the workpiece on the placing rack. And if the conditions are met, the workpiece switching die moves the recovered placing frame to a working position. The buffer door 203 is opened, and the clamping jaws 222 take the coated workpiece back to the placing frame and return to the original point. The buffer door is closed. At this time, the display 501 displays that the film coating is finished, prompts the staff to take out the workpiece with the finished film coating, and the system suspends the work.

When the staff takes out the rack with the film covering completed and puts back the empty rack, the display 501 will prompt that the next film covering operation can be performed.

When the work piece is coated with film in the work area, the rack (empty at this time, the work piece is sent into the work area) of the buffer area to be coated with film can be taken out, and after a new work piece is put in, the new work piece is put on the workbench 209 of the buffer area again.

Furthermore, the automatic coating equipment for the biosensor electrode is provided with three layers of re-closed spaces to reduce volatilization of membrane liquid, the coating process is carried out by a programmable computer controller control motor, the coating speed of an electrode needle can be controlled according to needs to control the thickness of the coating, the feeding depth of the motor is controlled to control the length of the coating, and the programming control can be carried out according to different needs.

The triple enclosed space, the first layer: the upper part of the film liquid box is provided with a film liquid box cover which can be automatically opened and closed. When the electrode needs to be coated with the film, the motor drives the film liquid box cover to be automatically opened, and after the film coating is finished, the film liquid box cover can be automatically closed. Therefore, the volatilization of the membrane liquid can be prevented to the maximum extent.

The triple enclosed space, the second layer: the working area is an openable closed space, and an atmosphere box is arranged in the working area to maintain the atmosphere of the working area in the film coating process, so that the volatilization of the film liquid is reduced.

The triple enclosed space, the third layer: between the working area and the outside of the apparatus, a buffer area is provided, in which an atmosphere box 206 is placed, in which the same solution as in the working area is stored, and which maintains the atmosphere in the buffer area after evaporation. There is a buffering door between workspace and buffering district, and when the work piece was through, the buffering door can be opened temporarily, because workspace and buffering district atmosphere are equal this moment, therefore the workspace atmosphere changes very little
