After detection is finished, doors of an inlet and an outlet of the vacuum box are opened, the workpiece and the tooling plate which are detected are conveyed out to the first output channel from the outlet of the vacuum box along the longitudinal direction, and after the tooling plate reaches the tail end of the first output channel, the third reversing conveying device positioned at the tail end of the first output channel is transversely conveyed to the second output channel and is conveyed out along the longitudinal direction by the second output channel.
In the existing multi-channel tunnel type refrigerating system detection system, when one workpiece is detected in a box, the next workpiece to be detected can only wait on the transverse second input channel, and at the moment, the second input channel can only pause. Because the transportation is orderly, workpieces can arrive earlier and enter the vacuum box for detection, but even if the tunnel type vacuum box completes the detection earlier, the workpieces to be detected on other stations are also parked on the second input channel which is suspended to run, so that the second input channel can be continuously run after the last vacuum box completes the detection; or even if the workpiece to be detected can be suspended on the second input channel through the jacking mechanism so as to keep the second input channel in the running state, the workpiece to be detected still causes obstruction to the transportation of the next workpiece to be detected of other stations on the second input channel. Therefore, the existing detection system can only synchronously and uniformly execute leak detection work on a plurality of refrigeration systems in a beat mode among a plurality of vacuum boxes, the continuity between the box outlet action of the last workpiece and the box inlet action of the next workpiece of the same vacuum box is lacked, the mode slows down the production beat, and the production efficiency is reduced.

Working method embodiment of tunnel type automatic box entering and exiting leakage detection system
The working method of the tunnel type automatic box entering and exiting leakage detection system comprises the following steps:
referring to fig. 1 to 4, the process plate carrying the heat exchanger workpiece to be tested flows on the first input line 11 until reaching the end of the first input line 11, the first jacking translation mechanism 121 on the second input line 12 is changed to the jacking state and with the first input line 11, the process plate carrying the workpiece reaches the second input line 12.
After the second input line 12 transports the process plates bearing the workpieces along the transverse direction and reaches the positions corresponding to the four tunnel type leak detection boxes 3, the corresponding first jacking translation mechanisms 121 are changed into jacking states, and the process plates bearing the workpieces are transferred to the area to be detected 200 by matching with the started transport line 2 of the area to be detected. If the tunnel type leakage detection box 3 is executing the detection work at the moment, the transportation line 2 of the area to be detected is suspended and waits; when the tunnel type leak detection box 3 completes the detection of the previous workpiece and opens the door, the internal translation mechanism 33 is started to send the previous workpiece out from the outlet 302, the transportation line 2 in the inspection area is started to be butted with the transportation line 2 in the inspection area, and the workpiece to be detected enters the detection space 300 from the inlet 301. Wherein, can be according to the infrared detection module of tunnel leak detection case 3 or can detect the detection data of the work piece position in tunnel leak detection case 3 other detection module in order to obtain the current position of last work piece in tunnel leak detection case 3, when a part of last work piece reachs outside export 302, or last work piece reachs outside export 302 completely, next work piece is sent into entry 301 from waiting to examine district's transfer line 2. Of course, the former is more advantageous in that a part of the previous workpiece reaches the outside of the outlet 302 and the next workpiece is fed into the inlet 301 from the inspection area transport line 2.
In addition, if no workpiece is in the tunnel type leak detection box 3, the internal translation mechanism 33 is started and is in butt joint with the transportation line 2 to be detected which keeps running, and the workpiece to be detected enters the detection space 300 from the inlet 301. In addition, in the case where process boards are not temporarily placed on all the inspection area transport lines 2, the second input line 12 may be kept in operation to transport the process boards to the vacant inspection area transport lines 2.
The process board bearing the workpiece after the detection is sent out of the tunnel type leak detection box 3 from the outlet 302 and is conveyed to a qualified line or an NG line according to the detection result.
Wherein, must keep advancing case, synchronous detection need mutual waiting and influence the problem of takt for solving among the prior art a plurality of detection stations. The second input line 12 is used as a common channel for feeding a plurality of detection stations, the invention is additionally provided with a to-be-detected area 200 and a plurality of to-be-detected area conveying lines 2 positioned in the to-be-detected area 200, under the arrangement, workpieces passing through the second input line 12 continuously and successively reach the plurality of to-be-detected area conveying lines 2 along time and successively enter the tunnel type leakage detection boxes 3 for detection, under the condition, the plurality of tunnel type leakage detection boxes 3 are in an asynchronous detection state, namely, although each tunnel type leakage detection box 3 needs to complete a plurality of same actions, time difference exists between the moments when the plurality of tunnel type leakage detection boxes 3 execute the same actions, for example, when one tunnel type leakage detection box 3 executes door closing actions, the adjacent or other tunnel type leakage detection boxes 3 respectively execute box entering, fine evacuation, helium gas leakage detection, air breaking, door opening and other actions.
Even if the moments when each tunnel type leakage detecting box 3 finishes the detection work are not consistent, because the actions among the tunnel type leakage detecting boxes 3 are independent, the workpiece to be detected is temporarily placed on the transportation line 2 of the area to be detected and is not temporarily placed on the second input line 12 any more to block the transportation of the second input line 12 pair, the tunnel type leakage detecting boxes 3 do not need to keep beat synchronization, after one station finishes the detection early and the workpiece in the area to be detected 200 enters the box, the next workpiece can rapidly reach the area to be detected 200 to be supplemented and wait for entering the box.
Therefore, the invention eliminates the mutual influence among a plurality of stations by additionally arranging the conveying line of the to-be-detected area, enhances the independence among a plurality of detection stations, ensures the continuity of the detection process of each detection station and well accelerates the production rhythm. In addition, unlike the assembly process, the leak detection process may also vary the duration of the detection depending on the leak detection situation. However, the invention does not require the synchronism among a plurality of detection stations, and realizes the independence of each station, so the detection beats of other stations are not influenced under the change, thereby effectively improving the production efficiency.
In other embodiments of the tunnel type automatic in-and-out box leakage detection system, only the to-be-detected area and the to-be-detected area conveying line can be arranged between the second input line and one of the tunnel type leakage detection boxes, and the blocking to the second input line can be reduced under the arrangement, so that the production beat is accelerated.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
