FIG. 2 is a diagram illustrating a boot state maintaining module passing through a plurality of testing machines according to an embodiment of the present invention. As shown in fig. 2, when the power-on state maintaining module A1 performs a testing process, the testing process sequentially passes through a first testing machine TS1, a second testing machine TS2, a third testing machine TS3, a fourth testing machine TS4 and a fifth testing machine TS5, wherein the first testing machine TS1, the second testing machine TS2, the third testing machine TS3, the fourth testing machine TS4 and the fifth testing machine TS5 are respectively responsible for testing whether the first function, the second function, the third function, the fourth function and the fifth function of the circuit board 100 to be tested are normal. The first tester TS1 is, for example, an OS tester, the second tester TS2 is, for example, a CAL tester, the third tester is, for example, an RF1 tester, the fourth tester is, for example, an RF2 tester, and the fifth tester TS5 is, for example, an FCT tester. The number of the test machines is only exemplary, and the invention is not limited thereto.
Before the power-on state maintaining module A1 enters the first tester TS1, the control circuit board 200 generates a connection between the circuit board to be tested 100 and the rechargeable battery 300 according to an external power-on command. When the circuit board 100 to be tested is connected to the rechargeable battery 300, the circuit board 100 to be tested can obtain the stored power from the rechargeable battery 300. After the circuit board to be tested 100 obtains the power stored from the rechargeable battery 300, the circuit board to be tested 100 is changed from the power-off state to the power-on state.
After the circuit board 100 to be tested is turned on, the power-on state maintaining module A1 enters the first testing machine TS1, and the first testing machine TS1 starts testing the first function of the circuit board 100 to be tested. After the first testing machine TS1 completes testing the circuit board 100 to be tested, the power-on state maintaining module A1 leaves the first testing machine TS1. Then, the test object enters a transport device (e.g., a conveyor belt) and moves toward the second test station TS2.
After the power-on state maintaining module A1 leaves the first testing machine TS1 and before it enters the second testing machine TS2, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the rechargeable battery 300, so that the circuit board 100 to be tested is maintained in the power-on state. When the power-on state maintaining module A1 moves to the second testing machine TS2, the second testing machine TS2 can immediately test the second function of the circuit board 100 to be tested because the circuit board 100 to be tested is already in the power-on state. After the second testing machine TS2 completes the test of the second function of the circuit board 100 to be tested, the power-on state maintaining module A1 leaves the second testing machine TS2. Then, the test object enters a transport device (e.g., a conveyor belt) and moves toward the third test station TS3.
After the power-on state maintaining module A1 leaves the second testing machine TS2 and before it enters the third testing machine TS3, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the rechargeable battery 300, so that the circuit board 100 to be tested is maintained in the power-on state. When the power-on state maintaining module A1 moves to the third testing machine TS3, since the circuit board 100 to be tested is already in the power-on state, the third testing machine TS3 can immediately test the third function of the circuit board 100 to be tested. After the third testing machine TS3 completes the testing of the third function of the circuit board to be tested 100, the power-on state maintaining module A1 leaves the third testing machine TS3. Then, the test object enters a transport device (e.g., a conveyor belt) and moves toward the fourth test station TS4.
After the power-on state maintaining module A1 leaves the third testing machine TS3 and before it enters the fourth testing machine TS4, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the rechargeable battery 300, so that the circuit board 100 to be tested is maintained in the power-on state. When the power-on state maintaining module A1 moves to the fourth testing machine TS4, since the circuit board 100 to be tested is already in the power-on state, the fourth testing machine TS4 can immediately test the fourth function of the circuit board 100 to be tested. After the fourth testing machine TS4 completes the test of the fourth function of the circuit board to be tested 100, the power-on state maintaining module A1 leaves the fourth testing machine TS4. Then, the test object enters a transport device (e.g., a conveyor belt) and moves toward the fifth test station TS5.
After the power-on state maintaining module A1 leaves the fourth testing machine TS4 and before it enters the fifth testing machine TS5, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the rechargeable battery 300, so that the circuit board 100 to be tested is maintained in the power-on state. When the power-on state maintaining module A1 moves to the fifth testing machine TS5, since the circuit board 100 to be tested is already in the power-on state, the fifth testing machine TS5 can immediately test the fifth function of the circuit board 100 to be tested. After the fifth testing machine TS5 completes the test of the fifth function of the circuit board to be tested 100, the startup state maintaining module A1 leaves the fifth testing machine TS5.
After the power-on state maintaining module A1 leaves the fifth testing machine TS5, since the circuit board to be tested 100 has completed testing all functions, the control circuit board 200 receives a power-off command from the external device, and cuts off the connection between the rechargeable battery 300 and the circuit board to be tested 100 according to the power-off command. When the connection between the rechargeable battery 300 and the circuit board 100 to be tested is cut off, the circuit board 100 to be tested cannot receive the power of the rechargeable battery 300, and therefore the circuit board 100 to be tested is switched from the power-on state to the power-off state.
FIG. 3 is a diagram illustrating an embodiment of a boot state maintaining module positioned on a first testing machine. As shown in fig. 3, the fixing frame 400 of the power-on state maintaining module A1 includes a plurality of positioning corners 401, and the first testing machine TS1 includes a plurality of positioning plates PB, when the power-on state maintaining module A1 enters the first testing machine TS1, two of the positioning corners 401 respectively abut against the positioning plates PB. In this way, when the first testing machine TS1 tests the circuit board 100 to be tested, the startup state maintaining module A1 is not easy to displace.
FIG. 4 is a diagram illustrating another embodiment of a power-on state maintaining module positioned on a first testing machine. As shown in fig. 4, the fixing frame 400 of the on-state maintaining module A1 further includes a plurality of positioning pillars 403, and the first testing machine TS1 includes a plurality of positioning holes PH, and when the on-state maintaining module A1 enters the first testing machine TS1, the positioning pillars 403 are respectively engaged with the positioning holes PH. In this way, when the first testing machine TS1 tests the circuit board 100 to be tested, the startup state maintaining module A1 is not easy to displace.
In other embodiments, the fixing frame 400 can be positioned on the first testing machine TS1 by abutting the positioning corner 401 against the positioning plate PB and engaging the positioning post 403 with the positioning hole PH.
FIG. 5 is a circuit functional block diagram of a boot state maintaining module according to a first embodiment of the present invention. As shown in fig. 5, the control circuit board 200 of the power-on state maintaining module A1 includes a microprocessor 201, a switch circuit 203, a first transmission interface IF1, a second transmission interface IF2 and a third transmission interface IF3, wherein the microprocessor 201 is electrically connected to the first transmission interface IF1 and the switch circuit 203, the first transmission interface IF1 is further electrically connected to a terminal device TD, such as a mobile communication device or a server. The second transmission interface IF2 is electrically connected to the rechargeable battery 300 and the switch circuit 203, and the third transmission interface IF3 is electrically connected to the switch circuit 203 and a fourth transmission interface IF4 of the circuit board to be tested 100, wherein the circuit board to be tested 100 includes a plurality of test points TP.

The second electrical pin 2033 of the switch circuit 203 is electrically connected to the second transmission interface IF2, and the third electrical pin 2035 of the switch circuit 203 is electrically connected to the third transmission interface IF3.
The microprocessor 201 of the control circuit board 200 receives a power-on command of the terminal device TD through the first transmission interface IF 1. Then, the microprocessor 201 sends a control signal to the switch circuit 203 according to the power-on command. When the switch circuit 203 of the control circuit board 200 receives a control signal of the microprocessor 201, the switch circuit 203 of the control circuit board 200 is switched from the off state to the on state. When the switch circuit 203 of the control circuit board 200 is in the on state, the power stored in the rechargeable battery 300 can be transmitted to the circuit board 100 to be tested via the second transmission interface IF2, the switch circuit 203 and the third transmission interface IF3. When the circuit board to be tested 100 obtains power from the rechargeable battery 300, the circuit board to be tested 100 is changed from the power-off state to the power-on state.

Comparing table 1 and table 2, the circuit board 100 to be tested of the present invention is maintained in the power-on state during each test item of the test process, so that the circuit board 100 to be tested does not need to be repeatedly powered on and off, thereby reducing the time required for the circuit board 100 to be tested to complete the test process.
When the circuit board 100 to be tested completes the testing process, the microprocessor 201 switches the switch circuit 203 from the on state to the off state, thereby cutting off the connection between the rechargeable battery 300 and the circuit board 100 to be tested. At this time, the circuit board to be tested 100 is changed from the power-on state to the power-off state.
