[0022] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein identical or similar labels denote identical or similar elements or components having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings.

[0024] Figure 1 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figure 2 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figure 3 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figure 4 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figure 5 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figure 6 The tool circuit board test circuit structure of the embodiment of the present application is described below in combination with the drawings. Figures 1-6 As shown in the drawings, the tool circuit board test circuit structure comprises a power module 1, a main control module 2 electrically connected with the power module 1, and a key trigger module 3, an indicator light module 4 and a photoelectric coupling module 5 electrically connected with the main control module 2; wherein the indicator light module 4 comprises N groups of first color indicator lights and second color indicator lights, and the photoelectric coupling module 5 comprises N groups of starting photoelectric relays and test photoelectric relays; the test photoelectric relays are arranged at a test platform.

[0025] Specifically, the power module 1 can be a DC-DC direct current power supply, and the DC-DC power supply chip ME3116AM6G is used to detect the voltage for oscillation output voltage by feedback pins. When the key is not pressed, the IO port is in a high flat signal state, and the main control MUC does not need to consider other program parts. When the key is pressed, the voltage pulls down the IO port from high resistance to low flat signal external interruption, and the running other program is temporarily interrupted, directly jumps to the detection key IO for judgment, and the red light is on. The photoelectric coupling transistor opens 24V from pin 3 to pin 4. The photoelectric coupling switch of the photoelectric coupling module 5 controls whether to pause, and when the tool motor rotates to the specified position, the opportunity opens the photoelectric coupling 3, 4 pins to enter the main control MCU of the test board to control one of the keys to stop working. The green light is on.

[0026] The test points of the circuit board are connected with the tool setting circuit board test circuit structure of the application through the test platform, and then the MCU of the master control module 2 will detect the part circuit of the optocoupler module 5, the part circuit of the key trigger module 3, the part of the driving optocoupler module 5, and the part circuit of the indicator light module 4 in sequence.

[0027] In one embodiment of the application, N=2 groups of test circuits are designed, and therefore N=2 groups of keys are arranged in the key trigger module 3. Figures 3-4 As shown in the embodiment, P6 and P7 keys are arranged in the embodiment.

[0028] 1. When the P6 key is pressed, the optocoupler part of U4 is driven, and the red light is on. When the motor on the tool setting circuit board rotates to a certain position in one direction, it is paused, the green light is on, and the red light is off.

[0029] 2. When the P7 key is pressed, the optocoupler part of U3 is driven, and the red light is on. When the motor on the tool setting circuit board rotates to a certain position in one direction, it is paused, the green light is on, and the red light is off.

[0030] 3. It is judged that the above two points are normal and qualified products.

[0031] The "certain position" in the above "when the motor rotates to a certain position in one direction" refers to the position that affects the photosensitive sensor in the test photoelectric relay.

[0032] According to the tool setting circuit board test circuit structure, 1. The efficiency of detecting the circuit board is improved; 2. The good and bad of the circuit board can be quickly judged through the indicator light; 3. It is convenient to use and can detect the good and bad without the machine tool, thereby reducing the loss.

[0033] According to one embodiment of the application, the power supply indicator light module 6 is electrically connected with the power supply module 1.

[0034] Specifically, the power supply indicator light module 6 is directly connected with the power supply, so that the indicator light of the power supply indicator light module 6 is lit after the test structure is powered on, and the user is informed that the test structure is ready for work.

[0035] According to one embodiment of the application, the wiring module 7 is further included, and the starting photoelectric relay and the test photoelectric relay in the optocoupler module 5 are electrically connected through the wiring module 7.

[0036] According to one embodiment of the utility model, in each group of starting photoelectric relay and test photoelectric relay, the light emitting side of starting photoelectric relay is connected with main control module 2, the photosensitive side of starting photoelectric relay is connected with wiring module 7, the light emitting side of test photoelectric relay is connected with wiring module 7, and the photosensitive side of test photoelectric relay is connected with main control module 2.

[0037] Specifically, in the test structure of the application, the photoelectric relay of each group in the optical coupling module 5 includes one starting photoelectric relay and one test photoelectric relay, and both types of photoelectric relays need to be designed with a specific circuit to operate, therefore, by using the wiring module 7 to connect the two types of photoelectric relays, the modules of the two types of photoelectric relays can be mass-produced, and the circuit is simplified when connected, thereby improving the production rate and yield rate and reducing the cost.

[0038] According to one embodiment of the utility model, the light emitting side of starting photoelectric relay is connected with main control module 2 through npn triode, wherein the base of npn triode is connected with main control module 2, and the emitter stage of npn triode is connected with the light emitting side of starting photoelectric relay.

[0039] Specifically, in the embodiment of the application, according to the above operation process, the starting photoelectric relay is triggered by the key, therefore, the control trigger through MCU can be realized by triode, and the use of triode can ensure the reliability of trigger control.

[0040] According to one embodiment of the utility model, the chip with model number HC32F003C4PA-TSSOP20 is used as the central controller.

[0041] Specifically, HC32F003C4PA-TSSOP20 is a low-power single-chip microcomputer with rich pins, rich and accurate control functions, and low price, which is conducive to reducing production cost.

[0042] The above embodiment is a preferred implementation scheme of the application, in addition to this, the application can also be implemented in other ways, and any obvious replacement without departing from the concept of the application is within the protection scope of the application.
