recorder

12a, 12b, or 12 c. Further, the control module 140 controls the waiting member 131 to convey the circuit board 2 to the conveyor 11 a.

The control module 140 connects and controls the conveying member 111 and the conveying sensing unit 112 of the conveyor 11 a. When the circuit board 2 is located on the conveying member 111, the control module 140 may control the conveying sensing unit 112 to sense the mark 20 of the circuit board 2 and determine whether the circuit board 2 is recorded or tested by the recorder 12 a. If the recorder 12a is the selected recorder 12a, the control module 140 can control the transportation component 111 to transport the circuit board 2 to the recorder 12a for recording or testing. If the burner 12a is not the selected burner 12b or 12c, the control module 140 may control the conveying member 111 to convey the circuit board 2 to the burner 12a and control the burner 12a to convey the circuit board 2 to the conveyor 11 b.

conveyors

11a, 11b, 11c, respectively. In addition, the control module 140 may also be a single control center.

If the track switching unit 122 of the

recorders

12a, 12b, 12c is located at the first position, it indicates that the

recorders

12a, 12b, 12c are in an idle state without recording the circuit board 2 at this moment. If the track switching unit 122 of the

recorders

12a, 12b, 12c is located at the second position, it indicates that the

recorders

12a, 12b, 12c are in the recording state of the recording circuit board 2 at this moment.

The control main unit 14 may control the dispensing sensing unit 132 to sense the label 20 of the circuit board 2 while the circuit board 2 is positioned at the waiting member 131. Furthermore, the control master unit 14 notifies the control slave units 14a, 14b, 14c to detect whether the

recorders

12a, 12b, 12c are idle or not and returns the detection result. If all the

recorders

12a, 12b, 12c are not idle, the circuit board 2 is continuously located in the waiting component 131 for waiting. When one of the

recorders

12a, 12b, 12c is in an idle state, the information of the mark 20 of the circuit board 2 is matched with the

recorder

12a, 12b or 12c in the idle state, and the information of the mark 20 of the circuit board 2 is transmitted to the control sub-unit 14a, 14b, 14c corresponding to the

recorder

12a, 12b or 12c in the idle state. If there are multiple

idle burners

12a, 12b, 12c, one of the

burners

12a, 12b, 12c can be selected as the idle burner according to the random number or the number of times the

burners

12a, 12b, 12c are used. The circuit board 2 may pass through the

burners

12a, 12b or 12c in the burning state, and may pass through the non-selected

idle burners

12a, 12b or 12 c.

When the track switching unit 122 is located at the first position, the control module 140 may determine to leave the circuit board 2 in the

recorder

12a, 12b, or 12c or to make the circuit board 2 pass through the

recorder

12a, 12b, or 12c according to the information of the mark 20 sensed by the conveying sensing unit 112. When determining that the circuit board 2 is left in the

recorder

12a, 12b or 12c, the control module 140 may control the transportation member 111 to transport the circuit board 2 to the first switching track 1221 of the track switching unit 122 of the

recorder

12a, 12b or 12c, control the

recorder

12a, 12b or 12c to leave the circuit board 2 in the first switching track 1221, control the track switching unit 122 to move from the first position to the second position, and control the recording unit 129 to record information on the circuit board 2. When the track switching unit 122 is located at the second position, the control module 140 can control the

recorder

12a, 12b or 12c to pass the circuit board 2.

For example, when the circuit board 2 is located in the waiting component 131, it is assumed that the detection result received by the control main unit 14 is that the first recorder 12a is in a recording state, the second recorder 12b is in a recording state, and the third recorder 12c is in an idle state. The control main unit 14 can select the third recorder 12c as the recorder 12c responsible for recording the circuit board 2 according to the random number, and transmit the information of the mark 20 of the circuit board 2 to the control sub unit 14 c. And conveys the circuit board 2 to the first conveyor 11 a.

At this time, the first recorder 12a is in the recording state, and the track switching unit 122 is located at the second position. The control sub-unit 14a may control the first conveyor 11a to convey the circuit board 2 to the first recorder 12a, and may control the second switching rail 1222 of the track switching unit 122 of the first recorder 12a to convey the circuit board 2 to the second conveyor 11 b. .

The second recorder 12b is in idle state, and the track switching unit 122 is in the first position. The control sub-unit 14b may control the conveyance sensing unit 112 of the second conveyor 11b to sense the marks 20 of the circuit boards 2. The control sub-unit 14b compares the matching information therein with the mark 20 of the circuit board 2 sensed by the conveying sensing unit 112 of the second conveyor 11b, and determines that the circuit board 2 is not matched with the second conveyor 11 b. The control sub-unit 14b may control the second conveyor 11b to convey the circuit board 2 to the second recorder 12b, and may control the first switching rail 1221 of the track switching unit 122 of the second recorder 12b to convey the circuit board 2 to the third conveyor 11 c.

The third recorder 12c is in idle state, and the track switching unit 122 is in the first position. The control sub unit 14c may control the conveyance sensing unit 112 of the third conveyor 11c to sense the mark 20 of the circuit board 2. The control sub-unit 14c compares the matching information therein with the mark 20 of the circuit board 2 sensed by the conveying sensing unit 112 of the third conveyor 11c, and can determine that the circuit board 2 matches the third conveyor 11 c. The control sub-unit 14c may control the third conveyor 11c to convey the circuit board 2 to the third recorder 12c, and may control the blocking member 127 of the third recorder 12b to catch down and position the circuit board 2. The control sub-unit 14c can control the track switching unit 122 of the third recorder 12b to move to the second position, and can control the recording unit 129 of the third recorder 12b to record information on the circuit board 2. When the third recorder 12b finishes recording the circuit board 2, the control sub-unit 14c can control the track switching unit 122 of the third recorder 12b to move to the first position, and can control the first switching track 1221 of the track switching unit 122 to transport the circuit board 2 away from the third recorder 12 c.

Referring to fig. 4 to 8, they are side views showing a process of recording or testing the circuit board 2 by the recorder 12a of fig. 1. The description will be made here with the recorder 12a as a representative. As shown in fig. 4, the recorder 12a is in an idle state, the track switching unit 122 is located at the first position, and the bearing 125 and the lower mold 126 of the recording fixture are far away from the recording unit 129. The first switching rail 1221 and the fixed rail 123 can receive the circuit board 2 shown in fig. 1 and pass the circuit board 2 shown in fig. 1.

As shown in fig. 5, when the control subunit 14a determines that the circuit board 2 on the first switching rail 1221 and the fixed rail 123 remains, the control subunit 14a controls the blocking member 127 to be lifted to the height of the first switching rail 1221 and the fixed rail 123, so as to block and position the circuit board 2. The control sub-unit 14a controls the position sensor 128 to detect whether the circuit board 2 is located on the first switching rail 1221 and positioned by the blocking member 127.

As shown in fig. 6, when the in-place sensor 128 detects that the circuit board 2 is located on the first switching track 1221 and is subjected to the blocking member 127, the control sub-unit 14a controls the first moving unit 124 to lift the carrier 125 and the lower recording jig 126, so that the carrier 125 and the lower recording jig 126 carry the circuit board 2 and are close to the recording unit 129. At this time, the circuit board 2 may be separated from the first switching rail 1221 and the fixed rail 123.

As shown in fig. 7, the sub-unit 14a is controlled to lift the movable member 1223 to lift the first switching rail 1221, the second switching rail 1222, the first moving unit 124, the carrier 125, the lower molding tool 126, and the circuit board 2. At this time, the track switching unit 122 is located at the second position, and the second switching rail 1222 and the fixed rail 123 may pass through the other circuit board 2'.

As shown in fig. 8, the control sub-unit 14a controls the second moving unit 1291 of the recording unit 129 to drive the upper mold 1292 of the recording jig to move downward to the circuit board 2, and record or test the circuit board 2. At this time, the track switching unit 122 is located at the second position, and the second switching rail 1222 and the fixed rail 123 may pass through the other circuit board 2'.

When the recording or testing is completed, the circuit board 2 may be placed back to the first switching track 1221 and the fixed track 123 in the sequence of fig. 7, fig. 6, and fig. 5, and the circuit board 2 may be transported to the next conveyor 11 b.

In summary, the automatic recording system according to an embodiment of the invention can control the track switching unit to be located at the first position or the second position by the control module. When the track switching unit is located at the first position, the circuit board can pass through or be located at the first switching track, and the control module can judge whether to send the circuit board into the recording unit for recording or to make the circuit board jump over the recorder for the next process. The control module can control the track switching unit to move to the second position so as to enable the first switching track to move towards the recording unit, and the circuit board can be switched to pass through the second switching track. When the track switching unit is located at the second position, the recording unit can record or test the circuit board, and other circuit boards can pass through the second switching track to jump over the recorder which is recording. Therefore, the automatic recording system can automatically carry out the transportation, recording and testing of the circuit board without manually transporting the circuit board or manually starting or ending the recording process of the circuit board. Therefore, the circuit board can be prevented from being hit by mistake by people, and unexpected situations caused by the physiological or psychological state of an individual can be avoided.
