Description
Technical Field

An existing automatic system for detecting leakage of a heat exchanger of an air conditioning chamber comprises a first input channel, a second input channel, a plurality of tunnel type vacuum boxes, a first output channel and a second output channel, wherein the first input channel is arranged in the longitudinal direction, the second input channel is arranged in the transverse direction, the tunnel type vacuum boxes are arranged in the transverse direction, the first output channel is arranged in the transverse direction, the second output channel is arranged in the longitudinal direction, a tooling plate bearing a workpiece to be detected is longitudinally conveyed on the first input channel and reaches the tail end of the first input channel, a first reversing conveying device positioned at the tail end of the first input channel is transversely conveyed into the second input channel, a second reversing conveying device is arranged in the second input channel and is respectively corresponding to the inlets of the tunnel type vacuum boxes, after the tooling plate reaches the second reversing conveying device, the tooling plate is longitudinally conveyed into the tunnel type vacuum boxes from the inlets, and then doors at the inlets and outlets of the tunnel type vacuum boxes are closed to form a vacuum space and carry out leakage detection on a refrigerating system. And after the tooling plate reaches the tail end of the first output channel, a third reversing and transferring device positioned at the tail end of the first output channel is transversely transferred to the second output channel and is longitudinally transported and sent out by the second output channel.
In the existing multi-channel tunnel refrigerating system detection system, when one workpiece is detected in a box, the next workpiece to be detected can only wait on a transverse second input channel, and at the moment, the second input channel can only pause operation. Because the transportation is orderly, the workpieces can arrive earlier and enter the vacuum box for detection, but even if the tunnel type vacuum box finishes detection earlier, the workpieces to be detected on other stations are also parked in the second input channel for suspending operation, so that the second input channel can be continuously operated after the last vacuum box finishes detection; or even if the workpiece to be detected can be overhead on the second input channel through the lifting mechanism to enable the second input channel to keep a 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 leak detection work can only be synchronously and uniformly executed on a plurality of refrigeration systems among a plurality of vacuum boxes of the existing detection system, and continuity is lacking between the box discharging action of the last workpiece and the box feeding action of the next workpiece of the same vacuum box.

Working method embodiment of tunnel type automatic box inlet and outlet leakage detection system
The working method of the tunnel type automatic in-out box leakage detection system comprises the following steps:
referring to fig. 1 to 4, the process plate carries the heat exchanger workpiece to be inspected and flows on the first input line 11 until reaching the end of the first input line 11, and the first lifting and translating mechanism 121 on the second input line 12 is shifted to a lifting state and is in contact with the first input line 11, and the process plate carrying the workpiece reaches the second input line 12.
After the second input line 12 conveys the process board carrying the workpiece in the transverse direction and reaches the position corresponding to the four tunnel type leak detection boxes 3, the corresponding first lifting and translation mechanism 121 is converted into a lifting state, and the process board carrying the workpiece is matched with the started conveying line 2 of the to-be-detected area and is conveyed to the to-be-detected area 200. If the tunnel type leak detection box 3 is executing detection work at the moment, suspending the transport line 2 in the area to be detected and waiting; 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, and meanwhile, the transport line 2 of the to-be-detected area is started to be in butt joint with the transport line 2 of the to-be-detected area, and the to-be-detected workpiece enters the detection space 300 from the inlet 301. The current position of the last workpiece in the tunnel type leak detection box 3 can be obtained according to the detection data of the infrared detection module of the tunnel type leak detection box 3 or other detection modules capable of detecting the position of the workpiece in the tunnel type leak detection box 3, and when a part of the last workpiece reaches the outside of the outlet 302 or the last workpiece completely reaches the outside of the outlet 302, the next workpiece is sent into the inlet 301 from the transport line 2 of the area to be detected. Of course, the former is more advantageous in that the next work piece is fed from the inspection area transporting line 2 to the entrance 301 when a part of the previous work piece reaches beyond the exit 302, and the tact is faster.
In addition, if no workpiece is present in the tunnel type leak detection box 3, the internal translation mechanism 33 is started and is in butt joint with the transport line 2 of the to-be-detected area kept running, and the to-be-detected workpiece enters the detection space 300 from the inlet 301. In addition, in the case that not all the inspection area transport lines 2 have the process board reserved thereon, the second input line 12 may remain operative to transport the process board to the empty inspection area transport line 2.
The detected process board carrying the workpiece is sent out of the tunnel leakage detection box 3 from the outlet 302, and is conveyed to a qualified line or an NG line according to the detection result.
The device solves the problem that in the prior art, a plurality of detection stations are required to be kept in the same step box, synchronous detection needs to be mutually waited, and the production beat is affected. The second input line 12 is used as a common channel for feeding a plurality of detection stations, the invention adds the to-be-detected area 200 and a plurality of to-be-detected area transportation lines 2 positioned in the to-be-detected area 200, under the arrangement, a workpiece passing through the second input line 12 continuously reaches the plurality of to-be-detected area transportation lines 2 along time and sequentially enters the tunnel type leak detection box 3 to carry out a detection procedure, in this case, a state that a plurality of tunnel type leak detection boxes 3 are asynchronously detected is formed, namely, although each tunnel type leak detection box 3 needs to complete a plurality of actions as well, a time difference exists between the moments that a plurality of tunnel type leak detection boxes 3 execute the same actions, for example, when one tunnel type leak detection box 3 executes a door closing action, the adjacent or other tunnel type leak detection boxes 3 begin to execute actions such as box advancing, fine evacuation, helium gas, air break, door opening and the like respectively.
Even if the time when each tunnel type leak detection box 3 completes the detection work is inconsistent, as the tunnel type leak detection boxes 3 act independently, the workpiece to be detected is temporarily placed on the transport line 2 of the area to be detected and is not temporarily placed on the second input line 12 any more to obstruct the transport of the second input line 12 pair, the tunnel type leak detection boxes 3 do not need to keep beat synchronization with each other, one station completes the detection earlier and after the workpiece of the area to be detected 200 enters the box, the next workpiece can quickly 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 transport line of the to-be-detected area, enhances the independence among a plurality of detection stations, ensures the continuity of the detection procedure of each detection station and well accelerates the production beat. In addition, unlike the assembly process, the leak detection process may also vary the detection duration depending on the leak detection condition. 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 the rest stations are not influenced under the change, thereby effectively improving the production efficiency.
In other embodiments of the tunnel type automatic in-out box leakage detection system, the to-be-detected area and the to-be-detected area transportation line between the second input line and one of the tunnel type leakage detection boxes can be used, the obstruction to the second input line can be reduced, and the production beat is accelerated.
Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the invention, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the invention, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the invention.
