Abstract
Description
Technical Field
[0001] The present application relates to the technical field of detection equipment, and in particular to a pressure-resistant device for detecting a crystal oscillator. Background Art
[0002] During the production process of crystal oscillators, metal casings are required. However, in order to ensure the quality of electronic components after production, the metal casings need to be subjected to pressure resistance testing to improve the overall quality of the manufactured electronic components.
[0003] After searching, it was found that in the existing technology, most of the electronic component shell compression testing equipment has a slot opened from the inside of the testing table to the upper end surface, and the inside of the slot is set with a testing product. The testing equipment cannot match the metal shell and cannot meet different models, and has low adaptability. At the same time, the safety is not high during the testing process, and it is easy to get pinched. Utility Model Content
[0004] The purpose of this application is to overcome the deficiencies in the prior art and to propose a pressure-resistant device for detecting a crystal oscillator;
[0005] This application is implemented through the following technical solutions:
[0006] The present application proposes a pressure resistance device for detecting a crystal oscillator, comprising a frame, a test device and an operating screen; the test device is arranged inside the upper part of the frame, and the operating screen is arranged on the top of the frame; the test device is used to perform a pressure resistance test on the crystal oscillator; the test device comprises a support, a pressure cylinder, a guide rod, an upper pressure plate and a lower pressure plate; the support is located in the middle of the operating area and is fixedly connected to the frame; the front side of the support is fixedly connected to a pressure cylinder; the lower end of the piston rod below the pressure cylinder is fixedly connected to an upper pressure plate, and a lower pressure plate is arranged below the upper pressure plate.
[0007] In one embodiment of the present application, the rack includes a cabinet and an operating area; the operating area is located above the cabinet; the test device is arranged inside the operating area, and the operating screen is arranged on the top of the operating area; there is an open window in front of the operating area; and test switches are arranged on both sides of the window.
[0008] In an embodiment of the present application, there are two test switches.
[0009] In one embodiment of the present application, a power switch, an indicator light, a buzzer and an emergency stop button are arranged above the window from left to right.
[0010] In one embodiment of the present application, guide rods are arranged on both sides of the pressure cylinder piston rod near the front; there are two guide rods, the lower ends of which are fixedly connected to the upper pressure plate; and the upper ends are slidably connected to the support through linear bearings.
[0011] In one embodiment of the present application, a crystal oscillator storage platform is provided at the top center of the lower pressure plate, and a limiting groove is provided inside the crystal oscillator storage platform; supporting feet are provided at the four corners of the bottom of the lower pressure plate.
[0012] In one embodiment of the present application, the crystal oscillator storage platform is detachable relative to the lower pressure plate.
[0013] In one embodiment of the present application, adjustment pins are provided at the four bottom corners of the upper pressing plate.
[0014] Compared with the prior art, the beneficial effects of this application are:
[0015] 1. The crystal oscillator storage table can be disassembled relative to the lower pressure plate. Due to the large number of crystal oscillator models, the crystal oscillator storage table used for the compression test of each crystal oscillator is different; and the limit groove opened on the top of the crystal oscillator storage table selected for different types of oscillators is consistent with the external contour of the crystal oscillator to be tested; this better meets the compression test of different types of oscillators;
[0016] 2. There are two test switches. When the crystal oscillator is clamped on the test device and needs to be tested, the operator needs to press the test switch with both hands at the same time so that the test device can be started.

[0030] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented.

[0031] The present application proposes a pressure-resistant device for detecting a crystal oscillator, comprising a rack 1, a test device 2 and an operation screen 3; the test device 2 is arranged inside the upper part of the rack 1, and the operation screen 3 is arranged on the top of the rack 1; the test device 2 is used to perform a pressure-resistant test on the crystal oscillator; the operation screen 3 is used to display and record various editing and test experimental parameters;
[0032] Please refer to Figure 1 In one embodiment, the rack 1 includes a cabinet 11 and an operating area; the operating area is located above the cabinet 11; the test device 2 is arranged inside the operating area, and the operating screen 3 is arranged at the top of the operating area; there is an open window in front of the operating area, which is convenient for the operator to install the crystal oscillator to be tested; at the same time, test switches 12 are arranged on both sides of the window; a power switch 13, an indicator light 14, a buzzer 15 and an emergency stop button 16 are arranged from left to right above the window; the power switch 13 is used to control the power supply of the entire device; the indicator light 14 is used to indicate the normal operation of the device; the buzzer 15 is used when the device is over-voltage or other equipment failure alarms; the emergency stop button 16 is a button for the operator to emergency brake when a sudden abnormal situation occurs;
[0033] The test switches 12 are preferably two; in this way, when the crystal oscillator is clamped on the test device 2 and needs to be tested, the operator needs to press the test switch 12 with both hands at the same time, so that the test device 2 can be started; in this way, the operator is forced to use both hands to start, which can effectively prevent the operator from being pinched and improve the anti-fool protection of the equipment.
[0034] Please refer to Figure 2 and Figure 3In one embodiment, the testing device 2 includes a support 21, a pressure cylinder 22, a guide rod 23, an upper pressing plate 4 and a lower pressing plate 5; the support 21 is located in the middle of the operating area and is fixedly connected to the frame 1; the front side of the support 21 is fixedly connected to the pressure cylinder 22; the lower end of the piston rod below the pressure cylinder 22 is fixedly connected to the upper pressing plate 4, and the lower pressing plate 5 is arranged below the upper pressing plate 4;
[0035] It is worth noting that guide rods 23 are arranged on both sides of the piston rod of the pressure cylinder 22 near the front; there are two guide rods 23, the lower ends of which are fixedly connected to the upper pressure plate 4; the upper ends are slidably connected to the support 21 through linear bearings; in this way, since the piston rod and the upper pressure plate 4 are connected to a supporting position, the upper pressure plate 4 may be deflected when the pressure cylinder 22 applies pressure; since the two guide rods 23 are respectively arranged at the front of the piston rod; in this way, the two guide rods 23 and the piston rod form a triangular positioning; in this way, when the upper pressure plate 4 moves up and down and applies pressure, the whole process is more stable;
[0036] Please refer to Figure 4 In one embodiment, a sensor 41 is provided above the upper pressure plate 4 near the front position connected to the piston rod. Since the area below this area is where the crystal oscillator is placed, the upper pressure plate 4 below this area is in direct contact with the crystal oscillator. Thus, the sensor 41 provided in this area can effectively monitor and record the pressure of the entire pressure resistance detection process.
[0037] Please refer to Figure 5 In one embodiment, a crystal oscillator storage platform 51 is provided at the top center of the lower pressing plate 5, and a limiting groove 52 is provided inside the crystal oscillator storage platform 51; supporting feet 53 are provided at the four corners of the bottom of the lower pressing plate 5; it should be noted that the crystal oscillator storage platform 51 can be disassembled relative to the lower pressing plate 5; due to the large number of crystal oscillator models, the crystal oscillator storage platform 51 used for the compression test of each crystal oscillator is different; and the limiting groove 52 provided on the top of the crystal oscillator storage platform 51 selected for different types of oscillators is consistent with the external contour of the crystal oscillator to be tested; this better meets the compression test of different types of oscillators;
[0038] At the same time, it is located to ensure that the crystal oscillator storage platform 51 is protected to a certain extent when over-pressure occurs; the four corners of the bottom of the upper pressing plate 4 are provided with adjustment pins 42; before product testing, the operator can adjust it according to the thickness of the crystal oscillator; in this way, when over-pressure occurs, the upper pressing plate 4 will continue to descend after the crystal oscillator is found to be deformed and damaged; in this way, when it continues to descend, the lower end of the adjustment pin 42 will contact the lower pressing plate 5 in advance; in this way, the upper pressing plate 4 is prevented from directly pressing on the top of the crystal oscillator storage platform 51, thereby protecting one end thereof;
[0039] It should be understood that overpressure generally refers to the predetermined pressure exceeding the pressure that the product can withstand; this situation is generally the pressure data to be collected when conducting a destructive pressure test;
[0040] Working principle:
[0041] First, the operator manually turns on the power switch 13, and the indicator light 14 lights up; then the operator operates the operation screen 3 to select and debug the test type and pressure data; then, the crystal oscillator storage table 51 that matches the crystal oscillator to be tested is replaced and installed above the lower pressure plate 5; then the crystal oscillator to be tested is installed in the limit groove 52 on the crystal oscillator storage table 51;
[0042] After the above preparations are completed, the operator presses the test switch 12 with both hands, so that the pressure cylinder 22 starts to start, causing the piston rod to drive the upper pressure plate 4 to move downward; when the upper pressure plate 4 applies pressure to the top of the crystal oscillator according to the set load, the sensor 41 thereon records the pressure of the entire process; the monitoring and recording of the pressure application area by the sensor 41 further improves the accuracy of data collection; when the test is completed, the pressure cylinder 22 will retract again for reset;
[0043] It should be noted that when it is necessary to test other types of crystal oscillators, it is only necessary to replace the corresponding crystal oscillator storage table 51; and then repeat the above operation; in this way, the compression resistance test of crystal oscillators of different types can be achieved.
[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
