Description

Technical Field

[0001] The utility model relates to the technical field of electrical testing devices, in particular to a CZT crystal testing system. Background Art

[0002] CZT crystals (cadmium zinc telluride crystals) have excellent optoelectronic properties and are widely used in fields such as X-ray detection, gamma-ray detection, neutron radiation detection, solar cells, lasers, and infrared detectors. For example, in X-ray detectors, CZT crystals can replace materials such as silicon and molybdenum, achieving better detection performance. In the laser field, CZT crystals can be used to manufacture components such as laser cavities and output windows. Existing CZT crystals (in sheet form) require performance testing before shipment. This typically involves applying a high voltage of approximately 2000V to the CZT crystal using a waveform detector. A circuit then reads the crystal's recognition waveform for a specific source to determine whether the crystal meets factory specifications. Due to the high detection voltage and the interference current generated by CZT crystals when exposed to light, the waveform detector must be electromagnetically shielded during the test, rendering the CZT crystal in a black box state. Furthermore, the tightness of the electrical connection between the waveform detector and the CZT crystal can affect the waveform detector's detection results. Currently available testing equipment struggles to meet these CZT crystal testing requirements. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figures 1 to 3 The utility model provides a CZT crystal testing system, which includes a testing box, a waveform detector 4 and a press-to-lock mechanism component.

[0025] The detection box includes a box 1 and a box cover 2 connected to the box 1 with an openable structure. Specifically, the surfaces of the box 1 and the box cover 2 are provided with an aluminum plate layer, so that the detection box has an electromagnetic shielding function. The edges of the box 1 and the box cover 2 are connected by hinges, so that the detection box can be opened conveniently.

[0026] A partition plate 3 is provided in the box 1, and the partition plate 3 divides the cavity in the detection box into a detection cavity and an electrical cavity, and the waveform detector 4 is enclosed in the electrical cavity; the box 1 is provided with a detection switch 11, an indicator light 12, a network connection port 13, and a power socket 14 connected to the waveform detector 4, wherein the power socket 14 is used to supply power to the waveform detector 4, the detection switch 11 and the indicator light 12 are used to control and display the working status of the power socket 14, and the network connection port 13 is used to connect to the host computer to output the detection results.

[0027] A detection plate 31 is embedded in the middle of the partition plate 3 , and a conductive foil is provided on the detection plate 31 . In this embodiment, the conductive foil is a copper foil. The conductive foil detection plate is used to support the CZT crystal to be tested.

[0028] The press-self-locking mechanism assembly is fixed on the partition plate 3, and the press-self-locking mechanism assembly is connected to the electrode rod 6. The electrode rod and the conductive foil are both connected to the waveform detector; the press-self-locking mechanism assembly is used to drive the electrode rod 6 to rise and fall and lock the position of the electrode rod, so that the end of the electrode rod 6 presses the CZT crystal to be tested, and the waveform detector 4 is powered on to detect the CZT crystal.

[0029] When the CZT crystal testing system is working, first place the sheet-shaped CZT crystal on the conductive foil, and then press the self-locking mechanism assembly. The pressing self-locking mechanism assembly drives the electrode rod 6 to press the upper surface of the CZT crystal, so that the waveform detector 4 is electrically connected to the CZT crystal through the electrode rod 6 and the conductive foil. Then close the detection box, press the detection switch 11, and the waveform detector 4 applies voltage to the CZT crystal. Then, the internal detection circuit reads the recognition waveform of the crystal for a specific power supply at this time, and outputs the recognition waveform to the host computer, thereby completing the detection of the CZT crystal.

[0030] During this process, pressing the self-locking mechanism assembly forces the electrode rods to press against the CZT crystal, thereby tightly connecting the waveform detector to the CZT crystal under test via the conductive foil and electrode rods, ensuring a tight and reliable electrical connection between the CZT crystal and waveform detector 4. The detection box encloses the CZT crystal within the detection cavity, and the detection box waveform detector within the electrical cavity. This reduces interference with the test results from light and induced electromagnetic waves, resulting in high accuracy, ease of operation, and safety.

[0031] Preferably, the push-lock mechanism assembly includes a protective cover 5, a push-lock mechanism, and a lifting slider 53. The protective cover 5 is fixed to the partition plate. A bracket 51 is provided within the protective cover 5. The bracket 51 is provided with a vertically arranged lifting guide rail 52. The lifting slider 53 is slidably disposed on the lifting guide rail. The electrode rod 6 is fixed to the lifting slider 53. The push-lock mechanism 56 is fixed to the bracket 51. The upper and lower ends of the push-lock mechanism 56 are respectively fixedly connected to the bracket 51 and the lifting slider 53. A conductive wire is connected to the upper end of the electrode rod 6, and the conductive wire passes through the partition plate and is connected to the waveform detector 4. Among them, the press-self-locking mechanism 56 is an existing module, which has two upper and lower travel points. Pressing the lifting slider 53 down can drive the press-self-locking mechanism 56 to move to the lower travel point. At this time, the lower end of the electrode rod 6 presses the CZT crystal. Pressing the lifting slider 53 again can reset the press-self-locking mechanism 56 to the upper travel point. At this time, the lower end of the electrode rod 6 is separated from the surface of the CZT crystal, which facilitates the replacement of the CZT crystal.

[0032] Preferably, the electrode rod 6 includes an electrode sleeve 61 and a lifting rod 62. A lifting hole is provided at the bottom of the electrode sleeve, and a closing block 64 is provided at the top of the electrode sleeve 61. The lifting rod 62 is slidably arranged in the electrode sleeve 61. The lower end of the lifting rod 62 passes through the electrode sleeve 61 and extends to the lower end of the electrode sleeve 61. A limiting protrusion 63 is provided at the upper end of the lifting rod 62. An elastic member is provided between the top of the lifting rod 62 and the closing block 64. In this embodiment, the elastic member is a coil spring 65. The lifting rod 62 is used to contact the CZT crystal, and the limiting protrusion 63 prevents the lifting rod 62 from falling off from the lifting hole. The combined structure of the electrode sleeve 61, the lifting rod 62 and the elastic member can make the electrode rod 6 an elastic telescopic structure, so that the electrode rod 6 can compensate for the pressing stroke of the pressing self-locking mechanism 56 during the pressing process, thereby ensuring that the lifting rod 62 can press the CZT crystal when it is in the lower stroke position, and preventing the pressing self-locking mechanism 56 from exerting too much pressure on the CZT crystal when pressing in the lower stroke position.

[0033] Preferably, a strip-shaped electrode holder 57 is fixed to the lifting slider 53. The electrode holder 57 is perpendicular to the lifting rail. One end of the electrode holder 57 is fixed to the lifting slider 53, and the other end of the electrode holder 57 is connected to the electrode rod 6. The electrode holder 57 is made of ABS, an engineering plastic with excellent structural strength and insulation performance, ensuring an insulated connection between the electrode rod 6 and the lifting slider 53 to prevent workers from electric shock.

[0034] Furthermore, a limiting slide groove is provided on the protective cover 5 , and the electrode holder 57 can be raised and lowered and limited in the limiting slide groove, and the limiting slide groove is used to ensure that the electrode holder 57 can be raised and lowered stably.

[0035] Furthermore, the push-to-lock mechanism assembly further includes a push-to-cover 55 , which is connected to the lifting slider 53 .

[0036] Furthermore, a connecting rod body 54 for connecting the pressing cover and the lifting slider 53 is provided between the pressing cover 55 and the lifting slider 53 , and a plurality of locking screws for connecting the lifting slider 53 and the pressing cover 55 are provided on the connecting rod body 54 .

[0037] Furthermore, an electromagnetic shielding net is embedded in the partition plate 3. The electromagnetic shielding net is a metal braided net covered with rubber. The metal braided net shields the waveform detector 4 in the electrical cavity, further improving the electromagnetic shielding effect of the detection box.
