Description

Power-on status retention module

The present invention relates to a power-on state holding module, and in particular to a power-on state holding module which enables a circuit board to be tested to maintain a power-on state.

After the circuit board is manufactured in the factory, it must go through a testing process. The testing process includes testing on different test machines. Only when every test item is qualified can it enter the market for sale.

When the circuit board to be tested enters the test machine, the test machine supplies power to the circuit board to turn on the circuit board to be tested, and then the test machine performs a functional test on the circuit board to be tested. After the circuit board to be tested leaves the test machine, the circuit board to be tested shuts down due to power failure, and the circuit board to be tested will not be turned on again until the circuit board to be tested moves to the next test machine. The more test machines the circuit board to be tested needs to pass through, the more times it needs to be repeatedly turned on and off. The more times it is repeatedly turned on and off, the more likely it is that the data of the circuit board to be tested will be lost and the probability of abnormal startup will increase.

The technical problem to be solved by the present invention is to provide a power-on state holding module in view of the deficiencies of the prior art.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a power-on state holding module, which includes a circuit board to be tested, a control circuit board and a charging battery. The control circuit board is electrically connected to the circuit board to be tested, and the charging battery is electrically connected to the control circuit board. When the power-on state holding module performs a test process, the control circuit board provides power from the charging battery to the circuit board to be tested, so that the circuit board to be tested is kept in a power-on state.

One of the beneficial effects of the present invention is that the power-on status holding module provided by the present invention, because when the circuit board to be tested is undergoing the test process, the charging battery continuously supplies power to the circuit board to be tested so that the circuit board to be tested is kept in the power-on state, so the circuit board to be tested is only powered on once and the time wasted by repeated power on and off is saved. In this way, the time required for the circuit board to be tested to complete the test process will be reduced. In addition, because the circuit board to be tested does not need to be repeatedly powered on and off, the probability of data loss and power-on abnormality is also reduced.

FIG1 is a perspective view of an embodiment of the power-on status holding module of the present invention. Referring to FIG1 and FIG2 together, the power-on status holding module A1 includes a circuit board to be tested 100, a control circuit board 200, a rechargeable battery 300 and a fixed frame 400. The circuit board to be tested 100 is, for example, a motherboard or a wireless network card, and the circuit board to be tested 100, the control circuit board 200 and the rechargeable battery 300 are fixed in the fixed frame 400.

Fig. 2 is a schematic diagram of an embodiment of the power-on state holding module of the present invention passing through multiple test machines. As shown in Fig. 2, when the power-on state holding module A1 performs a test process, it sequentially passes through a first test machine TS1, a second test machine TS2, a third test machine TS3, a fourth test machine TS4, and a fifth test machine TS5, wherein the first test machine TS1, the second test machine TS2, the third test machine TS3, the fourth test machine TS4, and the fifth test 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 test machine TS1 is, for example, an OS test machine, the second test machine TS2 is, for example, a CAL test machine, the third test machine is, for example, an RF1 test machine, the fourth test machine is, for example, an RF2 test machine, and the fifth test machine TS5 is, for example, an FCT test machine. The number of the above test machines is merely exemplary based on their test items, and the present invention is not limited thereto.

Before the power-on state holding module A1 enters the first test machine TS1, the control circuit board 200 connects the circuit board 100 to 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 power stored in the rechargeable battery 300. After the circuit board 100 to be tested obtains the power stored in the rechargeable battery 300, the circuit board 100 to be tested changes from the power-off state to the power-on state.

After the circuit board 100 to be tested is powered on, the power-on state holding module A1 enters the first test station TS1, and the first test station TS1 begins to test the first function of the circuit board 100 to be tested. After the first test station TS1 completes the test of the circuit board 100 to be tested, the power-on state holding module A1 leaves the first test station TS1, and then enters a transport device (e.g., a conveyor belt) and moves toward the second test station TS2.

After the power-on state holding module A1 leaves the first test machine TS1 and before entering the second test machine TS2, the control circuit board 200 still maintains the connection between the circuit board to be tested 100 and the charging battery 300, so the circuit board to be tested 100 remains in the power-on state. When the power-on state holding module A1 moves to the second test machine TS2, since the circuit board to be tested 100 is already in the power-on state, the second test machine TS2 can immediately test the second function of the circuit board to be tested 100. After the second test machine TS2 completes the test of the second function of the circuit board to be tested 100, the power-on state holding module A1 leaves the second test machine TS2. Then, it enters the transport equipment (such as a conveyor belt) and moves toward the third test machine TS3.

After the power-on state holding module A1 leaves the second test machine TS2 and before entering the third test 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 the circuit board 100 to be tested remains in the power-on state. When the power-on state holding module A1 moves to the third test machine TS3, since the circuit board 100 to be tested is already in the power-on state, the third test machine TS3 can immediately test the third function of the circuit board 100 to be tested. After the third test machine TS3 completes the test of the third function of the circuit board 100 to be tested, the power-on state holding module A1 leaves the third test machine TS3. Then, it enters the transport equipment (such as a conveyor belt) and moves toward the fourth test machine TS4.

After the power-on state holding module A1 leaves the third test machine TS3 and before entering the fourth test machine TS4, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the charging battery 300, so the circuit board 100 to be tested remains in the power-on state. When the power-on state holding module A1 moves to the fourth test machine TS4, since the circuit board 100 to be tested is already in the power-on state, the fourth test machine TS4 can immediately test the fourth function of the circuit board 100 to be tested. After the fourth test machine TS4 completes the test of the fourth function of the circuit board 100 to be tested, the power-on state holding module A1 leaves the fourth test machine TS4. Then, it enters the transport equipment (such as a conveyor belt) and moves toward the fifth test machine TS5.

After the power-on state holding module A1 leaves the fourth test machine TS4 and before entering the fifth test machine TS5, the control circuit board 200 still maintains the connection between the circuit board 100 to be tested and the charging battery 300, so the circuit board 100 to be tested remains in the power-on state. When the power-on state holding module A1 moves to the fifth test machine TS5, since the circuit board 100 to be tested is already in the power-on state, the fifth test machine TS5 can immediately test the fifth function of the circuit board 100 to be tested. After the fifth test machine TS5 completes the test of the fifth function of the circuit board 100 to be tested, the power-on state holding module A1 leaves the fifth test machine TS5.

After the power-on state holding module A1 leaves the fifth test machine TS5, since the circuit board 100 to be tested has completed the test of all functions, the control circuit board 200 receives a shutdown command from the external device, and according to the shutdown command, cuts off the connection between the rechargeable battery 300 and the circuit board 100 to be tested. 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 will not be able to receive the power of the rechargeable battery 300, so the circuit board 100 to be tested switches from the power-on state to the power-off state.

FIG3 is a schematic diagram of an embodiment of positioning the power-on state holding module in the first test machine. As shown in FIG3, the fixed frame 400 of the power-on state holding module A1 includes a plurality of positioning corners 401, and the first test machine TS1 includes a plurality of positioning plates PB. When the power-on state holding module A1 enters the first test machine TS1, two of the positioning corners 401 respectively contact the positioning plates PB. In this way, when the first test machine TS1 tests the circuit board 100 to be tested, the power-on state holding module A1 is not easily displaced.

FIG4 is a schematic diagram of another embodiment of positioning the power-on state holding module in the first test machine. As shown in FIG4, the fixed frame 400 of the power-on state holding module A1 also includes a plurality of positioning posts 403, and the first test machine TS1 includes a plurality of positioning holes PH. When the power-on state holding module A1 enters the first test machine TS1, the positioning posts 403 are respectively engaged with the positioning holes PH. In this way, when the first test machine TS1 tests the circuit board 100 to be tested, the power-on state holding module A1 is not easily displaced.

In other embodiments, the fixing frame 400 can achieve the effect of being positioned on the first testing machine TS1 by the contact between the positioning corner 401 and the positioning plate PB and the engagement between the positioning column 403 and the positioning hole PH.

FIG5 is a circuit functional block diagram of the first embodiment of the power-on status holding module of the present invention. As shown in FIG5, the control circuit board 200 of the power-on status holding 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. The microprocessor 201 is electrically connected to the first transmission interface IF1 and the switch circuit 203. The first transmission interface IF1 is also electrically connected to a terminal device TD, and the terminal device TD is, for example, 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 100 to be tested, and the circuit board 100 to be tested includes a plurality of test points TP.

In one embodiment, the circuit board 100 to be tested is, for example, a wireless network card or a motherboard, the switch circuit 203 is, for example, a metal oxide semiconductor field effect transistor, and the first transmission interface IF1, the second transmission interface IF2, and the third transmission interface IF3 are, for example, integrated circuit buses.

The switch circuit 203 of the control circuit board 200 includes a first electrical pin 2031, a second electrical pin 2033 and a third electrical pin 2035. The first electrical pin 2031 of the switch circuit 203 is electrically connected to the microprocessor 201. 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 the power-on command of the terminal device TD via the first transmission interface IF1. 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 the control signal of the microprocessor 201, the switch circuit 203 of the control circuit board 200 switches from the cut-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 100 to be tested obtains power from the rechargeable battery 300, the circuit board 100 to be tested changes from the shutdown state to the startup state.

Comparing Table 1 and Table 2, the circuit board 100 under test of the present invention is kept in the power-on state when performing each test item of the test process, so the circuit board 100 under test does not need to be repeatedly turned on and off, which reduces the time required for the circuit board 100 under test to complete the test process.

When the circuit board 100 to be tested completes the test process, the microprocessor 201 changes 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 100 to be tested changes from the on state to the off state.
