[0032] Please refer to Figure 1 , the insulating mounting plate 3 is arranged in the middle of the test rack 1, the to-be-tested circuit board 01 and the to-be-tested load are arranged above the insulating mounting plate 3, and the positioning plate 4 is arranged below the insulating mounting plate 3;

[0033] The insulating mounting plate 3 is usually made of insulating materials such as bakelite, so as to avoid short circuit caused by contact between the to-be-tested circuit board 01 or to-be-tested load and the positioning plate 4, and the connection between the insulating mounting plate 3 and the to-be-tested circuit board 01, to-be-tested load and positioning plate 4 is usually set as a common detachable connection mode such as clamping connection, bolt connection and pin connection.

[0034] Preferably, in order to stably mount the positioning plate 4 on the insulating mounting plate 3, the positioning plate 4 is provided with at least one positioning column and at least one connecting hole, the positioning column is clamped in the positioning hole of the insulating mounting plate 3, and the fastener such as connecting bolt or connecting pin is connected with the insulating mounting plate 3 after passing through the connecting hole of the positioning plate 4.

[0035] The positioning plate 4 is provided with a pin for connecting with the to-be-tested circuit board 01 and a load interface for mounting various to-be-tested loads, the positioning plate 4 and the to-be-tested circuit board 01 are usually connected through DB connectors, and the specific number and distribution of the two on the positioning plate 4 are determined according to the distribution of DB connectors on the to-be-tested circuit board 01 and the type and number of to-be-tested loads in actual detection.

[0036] Considering that the full-automatic sample adding and incubation system mainly has two main circuit boards of peripheral circuit board and temperature control circuit board, and the types of elements and circuit design of the two are different, the positioning plate 4 usually includes a peripheral positioning plate 41 and a temperature control positioning plate 42, wherein the peripheral positioning plate 41 is used for detecting whether the circuit board of the peripheral system is abnormal, and the temperature control positioning plate 42 is used for detecting whether the circuit board of the incubation system is abnormal.

[0037] When testing, the plug of the to-be-tested circuit board 01 is connected with the pin of the positioning plate 4, or the to-be-tested load is inserted into the load port of the positioning plate 4, so that the to-be-tested circuit board 01 or the to-be-tested load is electrically and signal connected with the positioning plate 4, so as to supply power to the to-be-tested circuit board 01 or the to-be-tested load through the positioning plate 4, and output the analog signal to the to-be-tested circuit board 01 or the to-be-tested load, so as to test whether each element of the to-be-tested circuit board 01 or the to-be-tested load is abnormal.

[0038] In the embodiment, the positioning plate 4 can simultaneously test each element of the to-be-tested circuit board 01 or multiple to-be-tested loads, without frequently replacing the testing equipment or load accessories in the troubleshooting process, thereby significantly reducing the equipment cost of maintenance and troubleshooting, simplifying the maintenance and troubleshooting process, and improving the troubleshooting efficiency and accuracy.

[0039] On the basis of the above embodiment, in order to ensure the close connection between the to-be-tested circuit board 01 and the positioning plate 4, a pressing assembly 2 for pressing the to-be-tested circuit board 01 to the positioning plate 4 can also be provided, and the pressing assembly 2 comprises a pressing plate 25 provided with a plurality of insulating pressing columns 251 at the bottom and a power mechanism, and the moving end of the power mechanism is connected with the top surface of the pressing plate 25, so as to drive the pressing plate 25 to ascend and descend along the height direction.

[0040] The pressing plate 25 can contact the to-be-tested circuit board 01 through the insulating pressing columns 251 at the bottom, and apply pressure to the to-be-tested circuit board 01, so that the to-be-tested circuit board 01 and the positioning plate 4 are closely connected, and the problem of poor contact between the to-be-tested circuit board 01 and the positioning plate 4 is avoided.

[0041] The insulating pressing columns 251 can be an integral structure with the pressing plate 25, or can be detachably installed on the bottom surface of the pressing plate 25 through bolt connection, pin connection or the like;

[0042] In consideration of the fact that the insulating pressing columns 251 will directly contact the to-be-tested circuit board 01, in order to prevent the insulating pressing columns 251 from damaging the to-be-tested circuit board 01, the insulating pressing columns 251 are usually made of rubber or other insulating elastic materials; in addition, the insulating pressing columns 251 should be arranged away from each element of the to-be-tested circuit board 01, so as to avoid damage to the elements of the to-be-tested circuit board 01 during the pressing process.

[0043] The power mechanism is used to drive the pressing plate 25 to ascend and descend along the height direction, and apply pressure to the to-be-tested circuit board 01 through the insulating pressing columns 251 at the bottom of the pressing plate 25; the power mechanism can be a mechanical mechanism, which is manually operated to realize the ascending and descending of the pressing plate 25, or can be internally provided with a power source to automatically drive the pressing plate 25 to ascend and descend.

[0044] In the embodiment, the to-be-tested circuit board 01 is pressed on the positioning plate 4 by the pressing assembly 2, so that the to-be-tested circuit board 01 and the positioning plate 4 are stably inserted, the poor contact between the to-be-tested circuit board 01 and the positioning plate 4 is avoided, the test result is affected, and the accuracy of the test result is ensured.

[0045] In order to simplify the structure of the power mechanism and reduce the cost of the equipment, preferably, the power mechanism comprises a pressing handle 21, a positioning sleeve 22, a positioning seat 23 and a pressing rod 24, the pressing rod 24 is vertically connected to the top surface of a pressing plate 25, one end of the positioning sleeve 22 is connected to the top of the pressing rod 24, the other end of the positioning sleeve 22 is hingedly connected to the bottom of the pressing handle 21, and the positioning seat 23 is used for clamping the positioning sleeve 22 to fix the height of the pressing rod 24.

[0046] Please refer to Figure 1 When the positioning sleeve 22 is clamped on the positioning seat 23, the height of the positioning sleeve 22 is limited by the positioning seat 23, and the height of the pressing rod 24 is fixed, at this time, the pressing rod 24 drives the pressing plate 25 to separate from the to-be-tested circuit board 01, the to-be-tested circuit board 01 can be taken and placed, and the power mechanism can be stored when the troubleshooting device is not used.

[0047] When the to-be-tested circuit board 01 is aligned with the positioning plate 4, the pressing handle 21 can be manually controlled to move away from the positioning seat 23, so that the positioning sleeve 22 is separated from the positioning seat 23, at this time, the pressing handle 21 is no longer limited by the positioning seat 23, the pressing handle 21 can be further pressed down to drive the pressing rod 24 and the pressing plate 25 to move downward along the height direction, until the to-be-tested circuit board 01 is tightly inserted with the positioning plate 4.

[0048] Considering that the horizontal displacement of the pressing handle 21 is inevitable, the horizontal displacement of the pressing plate 25 relative to the to-be-tested circuit board 01 occurs, and there is a risk that the insulating pressing column 251 directly presses the elements on the to-be-tested circuit board 01.

[0049] Preferably, in order to avoid the above risk, the power mechanism further comprises a guide column 26 arranged along the height direction, and the pressing plate 25 is slidably sleeved on the guide column 26 through a guide sleeve, so as to limit the horizontal displacement of the pressing plate 25 relative to the to-be-tested circuit board 01.

[0050] On the basis of the above embodiment, in order to avoid the communication circuit of the to-be-tested circuit board 01 from being faulty and affecting the detection result, the control device 5 can comprise at least one communication module, and the communication module is used for interacting with the communication circuit of the to-be-tested circuit board 01 to detect whether the communication circuit of the to-be-tested circuit board 01 is faulty.

[0053] When the power supply current of the to-be-tested circuit board 01 detected by the circuit detection module is 0, the control device 5 can determine that there is an open circuit fault in the to-be-tested circuit board 01.

[0054] On the contrary, when the power supply current of the to-be-tested circuit board 01 detected by the circuit detection module is far greater than the preset maximum current, the control device 5 can determine that there is a short circuit fault in the to-be-tested circuit board 01.

[0055] On the basis of the above embodiment, in order to facilitate the display of the test results, the control device 5 can further include a display screen 52, which is signal connected with the main control board 51 and is used to display the test results of the to-be-tested circuit board 01 or the to-be-tested load.

[0059] The main control board 51 is electrically connected with the positioning plate 4 through a DB25 interface and is signal connected with the positioning plate 4 through the communication module, and the communication module includes a 232 communication circuit, a 485 communication circuit and a CAN communication circuit, wherein the 232 communication circuit is mainly used for signal connection with the positioning plate 4, and the 485 communication circuit and the CAN communication circuit are mainly used for signal connection with the to-be-tested circuit board 01, so as to confirm whether there is a fault in the communication circuit of the to-be-tested circuit board 01.

[0060] The main control board 51 collects the current signal and the voltage signal of the to-be-tested circuit board 01 or the to-be-tested load through the current detection module and the voltage detection module, so as to detect whether the to-be-tested circuit board 01 has a short circuit or a short circuit fault, wherein the current detection module can adopt a high-precision resistor as a sampling resistor to form a subtracter circuit, so as to intercept the voltage across the sampling resistor, and then use an amplification circuit to amplify and collect the current signal, and the voltage detection module can be set as an AD collection circuit.

[0061] The main control board 51 receives and processes the feedback signal through the PMW processing module and the optocoupler feedback module, and delivers the processed feedback signal to the data processing module for abnormality judgment, wherein the PMW processing module is used for receiving and processing the PWM wave signal fed back by the fan, the lamp strip and other elements, and the optocoupler feedback module is used for receiving and processing the high-low level signal fed back by other elements.

[0063] When it is necessary to detect the to-be-tested load, the to-be-tested load is connected to the load socket corresponding to the positioning plate 4, the switch control module of the main control board 51 is turned on, the positioning plate 4 outputs an analog signal to the to-be-tested load and receives a feedback signal, the main control board 51 judges whether the to-be-tested load is normal according to the feedback signal, and outputs the test result to the display screen 52 through the display module.

[0064] When it is necessary to detect the to-be-tested circuit board 01, the to-be-tested circuit board 01 is connected to the positioning plate 4, the switch control module of the main control board 51 is turned on, and the current detection module is used to judge whether the to-be-tested circuit board 01 has a short circuit or a short circuit fault; after it is confirmed that the to-be-tested circuit board 01 has no short circuit or short circuit fault, the main control board 51 outputs an analog signal to each element of the to-be-tested circuit board 01 through the positioning plate 4, judges whether the to-be-tested circuit board 01 receives the analog signal through the communication module, so as to judge whether the communication module of the to-be-tested circuit board 01 has a fault; after it is confirmed that the communication circuit of the to-be-tested circuit board 01 has no fault, the main control board 51 receives the feedback signal of each element of the to-be-tested circuit board 01 through the positioning plate 4, judges whether each element is normal according to the feedback signal, and finally outputs the test result to the display screen 52 through the display module.
