Description

Technical Field

[0001] This utility model relates to the field of wire EDM PCI control card testing, and in particular to the field of multi-station integrated testing technology, specifically an integrated multi-functional testing box for wire EDM PCI control cards. Background Technology

[0002] During the production process, when performing functional tests on the wire EDM PCI motion control card, it is necessary to manually connect and verify more than 80 functions (such as XA / XB / XCXD / XE / YA-YE / UA-UC / VA-VC signals, as well as modules such as wire feeding, high frequency, power amplifier, and water pump). Each functional test requires manual connection of the interface of the signal under test (such as oscilloscope, multimeter, relay, etc.). Each connection takes an average of 1-2 minutes. The physical connection process alone takes 2-3 hours per card for the 80 tests, which greatly affects production efficiency.

[0003] Furthermore, repeated manual insertion and removal can easily lead to poor contact or misalignment, which may be misjudged as a functional failure; according to statistics from the defective card return department, 5%-10% of defective cards are due to connection errors.

[0043] This utility model proposes an integrated multi-functional test box for wire-cut PCI control cards, which is used in the integrated testing process of wire-cut PCI cards. This utility model does not limit the type of wire-cut PCI control card to be tested, but the structure of the test platform 1, cover 2, integrated test board 3 and heat dissipation module 4 is particularly suitable for one-time testing of multiple cards and multiple functions.

[0044] Overall, the integrated wire-cut PCI control card multi-functional testing box proposed in this utility model mainly includes: a testing platform 1, a cover 2, an integrated testing board 3, and a heat dissipation module 4. (See also...) Figure 1 and 3 It shows the arrangement of the testing platform 1, the housing 2, the integrated testing board 3 and the heat dissipation module 4.

[0045] This invention proposes an integrated multi-functional testing box for wire EDM PCI control cards. In use, the COM interface 324 is connected to a PC display screen. The wire EDM PCI control card to be tested is inserted sequentially into the PCI slot 321. The DB25 and DB15 male ports on one of the PCI control cards are connected to the DB25 signal port 311 and DB15 signal port 312 on the function status indicator board 31 via a connecting cable. During testing, the FPGA chip 322 performs functional signal tests on the PCI control card under test. Simultaneously, the corresponding detection signal transmission group 313 lights up. Whether there is a problem can be clearly observed through the color of the LEDs in the detection signal transmission group 313. Meanwhile, the status results of the function status indicator board 31 are fed back to the main test board 32 through the signal connection cable 35. The main test board 32 can directly display the test result data on the PC display screen through the COM port. After the test of the wire EDM PCI control card is completed, the connection cable of the DB25 signal port 311 and the DB15 signal port 312 is immediately connected to the PCI control card in the remaining untested PCI slot 321. Then, the tested wire EDM PCI control card is plugged in and unplugged into the new wire EDM PCI control card to be tested. This cycle is repeated, which has high testing efficiency and can test multiple items on the integrated wire EDM PCI control card at the same time. At the same time, reserving several PCI slots 321 can save the time of waiting for card replacement.

[0046] The aforementioned testing platform 1 has raised columns 11 around its bottom perimeter, with an air intake space reserved at the bottom. The cover 2, consisting of a hollow cavity 21 formed by the four side walls, has its bottom opening bolted to the center of the top of the testing platform 1. During testing, the integrated testing board 3 is energized. If a person touches the integrated testing board 3 directly with bare hands while inserting the PCI control card, it may cause a short circuit or electrostatic discharge, damaging the testing equipment. The cover 2 also serves as a dustproof barrier during the device's resting period. The cover 2 can be made of transparent plastic, providing insulation and allowing direct observation of the detection signal transmission group 313 on the function status indicator board 31 to understand the testing progress. During the testing process, the detection signal... The LEDs in the transmission group 313 will light up one by one as the signal detection progresses. The yellow light indicates the start of detection, the green light indicates success, and the red light indicates an error. Finally, the housing 2 will cause heat accumulation on the integrated detection board 3. A heat dissipation module 4 is designed to exchange the air inside the housing 2 with the outside. The heat dissipation module 4 includes: an air inlet waist-shaped hole 41, an air outlet grille slot 42, and an air intake fan 43. The air inlet waist-shaped hole 41 is evenly spaced and is opened on the detection platform 1 directly below the function status indicator board 31 and the main test board 32. The air outlet grille slot 42 is opened at equal intervals on the left and right sides of the housing 2. The air intake fan 43 is installed at intervals at the bottom of the detection platform 1 by bolt connection to blow outside air into the cavity 21 and exhaust the air inside the cavity 21.

[0047] The aforementioned integrated testing board 3 includes: a function status indicator board 31 and a main test board 32. The function status indicator board 31 and the main test board 32 are not in contact with each other. Data connection ports 34 are provided on the top sides of the function status indicator board 31 and the main test board 32, which are close to each other. The data connection ports 34 of the function status indicator board 31 and the main test board 32 are connected by a signal connection cable 35. Nut posts 33 are provided around the bottom of the function status indicator board 31 and the main test board 32. Mounting bolts are installed in the nut posts 33. The function status indicator board 31 and the main test board 32 are connected to the testing station 1 by the mounting bolts. The nut posts 33 hold the integrated testing board... 3. A heat dissipation channel is formed by raising the panel. DB25 signal port 311 and DB15 signal port 312 are provided on the side of the top of the function status indicator board 31 away from the top of the main test board 32. Detection signal transmission group 313 composed of optocoupler resistors, LED transistors and other components are arranged at equal intervals on the top of the function status indicator board 31. Several PCI slots 321 are arranged on the side of the top of the main test board 32 away from the function status indicator board 31. An FPGA chip 322 and several capacitor groups 323 are located on the top of the main test board 32 between the PCI slots 321 and the data connection port 34. The capacitor groups 323 play a voltage stabilizing role in the main test board 32.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
