[0056] An output power module board 2061 is used for providing adjustable DC voltage source to the sample to be tested or other users, various voltages such as 110VAC / 60HZ and 220VAC / 50HZ are ensured for normal operation of various module boards.
[0057] A comprehensive module board 2062 is used for containing different test circuits, such as current test, voltage test or other types of circuits, the test circuits are all known circuits, and the structure of the circuit itself is not in the scheme of the application, different performance tests are realized by setting different types of test circuits.
[0058] A channel module board 2063 is used for connecting the sampling point signal of the sample to be tested to a sampling device, such as a digital multimeter, which can clearly display for people to view.
[0059] A driving module board 2064 is used for driving various devices, such as electromagnetic valves and relays, to realize on-off control of current, voltage or corresponding signals, such as controlling the action of the cylinder installed on the gantry.
[0060] A signal module board 2065 is used for collecting and analyzing various analog signals and digital signals (such as amplitude, period, high-low frequency duration, etc.), and outputting various common signals (such as square wave, sine wave, magnetic field signal, etc.).
[0061] A main control module board 2066 is used for controlling all other module boards through a communication bus to complete the test of the sample to be tested.
[0062] Precise power module boards 2067 are provided in the embodiment, and two precise power module boards are used for providing mutually isolated multi-channel independent DC power output, and are mainly used for power supply of loads with extremely high power ripple requirements (such as analog single lithium battery, etc.).
[0063] The main circuit board 205 serves as a carrier of each module, provides power input to each module board, and communicates with the host computer. Each module board relays signals through the main circuit board to realize corresponding functional control.
[0064] The switching circuit board 207 has a plurality of connection ports for collecting external interfaces of each module board, so as to have generalization, standardization, facilitate unified connection, and have strong versatility.
[0065] The above listed are some basic types of functional circuit boards. The circuits set on each module board are all known circuits, and the corresponding module boards can be flexibly added or reduced according to actual test requirements. Generally, more functional circuit boards are preset, so as to have wider applicability. The control box is a fixed module and cannot be easily replaced. More functions can provide test conditions for different products.
[0066] The test components in the jig box 3 are a condition circuit board 307 and a load 308. The condition circuit board 307 is used to provide various test conditions. The condition circuit board 307 is connected to the switching circuit board 207 through a flexible cable. The length of the flexible cable is greater than the interval distance between the condition circuit board and the switching circuit board. By using a longer flexible cable to connect the condition circuit board and the switching circuit board, the flexible cable between the control box and the jig box can still be connected when the control box is moved away alone but maintains a certain distance. The test platform can still maintain a powered-on working state. The flexible cable connection mode is combined with the separable three structural modules, which is more convenient for maintenance process detection.

The condition circuit board in the jig box is a replacement module, which changes the corresponding condition package according to the test requirements of the sample to be tested. That is, only the condition circuit board in the jig box needs to be replaced for different test products, which is more simple to operate.

[0072] For the overall layout of the jig box, the top is divided into two parts, one part is the flip back door 302 located on the rear side, and the other part is the test area 301 located on the front side. The gap between the recessed position on the flip back door and the test area is formed after the flip back door is closed. The corresponding jig box inside the test area is used to install the condition circuit board, and the corresponding needle bed is arranged. The setting of the flip front door is mainly to facilitate the assembly and maintenance of the condition circuit board.

The control box positioning pin and the jig box positioning pin are used for positioning first, and then locked and mounted, so that the assembly accuracy can be ensured. Moreover, since the jig box is directly assembled on the bottom plate, the jig positioning hole can be formed by arranging a slot on the side of the bottom surface of the jig box close to the back panel, the slot extends to the back side of the jig box, the jig box can be directly placed on the bottom plate, and then pushed towards the jig box positioning pin to make the jig box positioning pin enter the slot, without placing from top to bottom, so that the installation operation is simple.
[0076] The control box can be assembled first, and then the jig box is installed, the bottom surface of the control box just falls on the flip back door part of the jig box, at this time, the jig box needs to be pushed from one side of the bottom plate until the jig positioning hole is clamped with the jig box positioning pin, and then locked through screws. Or the jig box is installed first, at this time, the jig box positioning pin can be assembled from top to bottom towards the jig box positioning pin to make the jig box positioning pin inserted into the jig positioning hole, and then the control box is installed after the jig box is locked.

[0078] The installation of the functional circuit board is realized through the guide rail assembly, which greatly reduces the assembly difficulty of the functional circuit board and reduces the assembly technical requirements for the operator. Moreover, the connection between the main circuit board and the functional circuit board and the connection between the functional circuit board and the adapter circuit board are realized through the terminal plug-in mode, the communication of the electric signal is realized, the complicated power lines or data lines do not need to be arranged, or the welding treatment of the lines is not needed, and only the direct plug-in of the terminal is used. For example, the plug-in port is arranged on the main circuit board, and the plug-in terminal is arranged on the functional circuit board. The plug-in terminal is directly inserted into the plug-in port, so that a plurality of lines do not need to be arranged in the box, the neatness of the box is maintained, and since the lines are reduced, the subsequent maintenance difficulty is also reduced.
[0079] For the main circuit board, the functional circuit board and the adapter circuit board, the main circuit board and the adapter circuit board are fixed in the horizontal direction, and the functional circuit board is assembled in the vertical direction.

Moreover, when the functional circuit board 206 is assembled, the functional circuit board 206 only needs to be slid and pushed along the guide groove, which is very convenient. The functional circuit board 206 does not need to be additionally fixed by a fixing device, and the cumbersome procedures of installing a plurality of screws in the box are saved, so that the assembly efficiency is effectively improved.

For example, the upper cavity 208 can house devices such as a solenoid valve 214 and a power supply 213. By dividing the enclosure into two independent cavities, it is not necessary to house all electrical components (such as power supplies and solenoid valves) and circuit boards in the same cavity. Separate installation facilitates individual inspection and maintenance and prevents mutual interference. The main circuit board can be connected to the electrical components installed in the upper cavity via a top plate.
[0085] A sliding cover 211 is also provided on the upper part of the housing 201 to facilitate covering the upper cavity 208 and opening it, providing convenience. A slot structure can be set on the top of the housing to cooperate with the sliding cover, so as to realize the stable sliding and limiting of the sliding cover.
[0086] For the specific testing process of this invention:
[0087] like Figure 8 As shown, place the sample to be tested on the test area of the fixture box, start the host computer, obtain the sample ID, and then start the test task.
[0088] The main circuit board provides a communication bus for each module board. First, it sends a command to the drive module board via the communication bus to control the cylinder's movement. Then, it sends a command to the signal module board to detect the cylinder's position information in real time. When the cylinder is detected to have reached the target position, it sends a command to the drive module board to stop the cylinder drive and keep the cylinder position fixed.
[0089] At this point, the power supply module board is controlled via the communication bus to provide the power required for various tests; then the drive module board is controlled via the communication bus to drive the switching actions of various tests; then the signal module board is controlled via the communication bus to collect and provide the signals required for various tests; and the condition circuit board is controlled via the communication bus to provide the test conditions required for various tests, and the measured data is uploaded to the server for storage.
[0090] Finally, the host computer and each module board work closely together through the communication bus to exchange test data and complete the testing of the sample.
[0091] After the test is completed, control the cylinder to reset and remove the product.
[0092] In summary, the main purpose of this invention is to provide a modular testing platform that allows for testing of different products simply by replacing the condition circuit board in the fixture box. Utilizing the guide rail assembly inside the control box to assemble the functional circuit boards reduces installation difficulty, improves assembly efficiency, and increases space utilization.
