Description

Technical Field

[0001] The present invention belongs to the technical field of computer hardware detection, and particularly relates to a device for detecting the anti-drop performance of computer hardware. Background Art

[0002] As the core hardware, the computer motherboard integrates numerous precision components. To ensure the structural stability of the motherboard, by detecting the anti-drop performance of the motherboard, it can be ensured that its structure remains intact and its functions are normal in case of accidents, reducing the risk of damage and protecting the user data security and usage experience.

[0003] In today's computer motherboard production process, after the motherboard is manufactured, its anti-drop performance must be strictly detected. This is because bumps and collisions during transportation or accidental drops during daily use may threaten the safety of the motherboard. To detect whether the motherboard has sufficient structural stability, anti-drop detection of the motherboard is required. For example, the professional detection devices disclosed in the patent publication number CN221667737U generally adopt the method of clamping and fixing the motherboard, lifting it to a specific height and then letting it free fall for testing. However, a single drop can only simulate the falling situation in one posture and is difficult to comprehensively reflect the anti-drop performance of the motherboard. If multiple clamping and testing are carried out, not only the operation is cumbersome, time-consuming and laborious, but also potential hidden damages inside the motherboard caused by the previous drops may interfere with the accuracy of the subsequent test results and cannot accurately judge the true anti-drop level of the motherboard. Summary of the Invention

[0004] The purpose of the present invention is to address the above problems and provide a device for detecting the anti-drop performance of computer hardware.

[0014] Preferably, each of the temperature measuring mechanisms includes a group of support sleeves fixedly installed on the inner wall of the box body, and the support sleeves correspond to the top of the detection table. A piston is slidably connected inside each of the support sleeves. Two connecting rods are fixedly installed on the side wall of the piston, and the two connecting rods are fixedly connected to a pressing heat conducting plate together. A plurality of uniformly distributed temperature detection probes are installed on the side wall of the pressing heat conducting plate.

[0017] Compared with the existing technology, the advantages of a computer hardware anti-drop performance detection device are as follows:

[0018] 1.

It is not necessary to directly simulate the motherboard falling. With one clamping, the detection of different angles can be completed, which is beneficial to improving the detection efficiency and comprehensiveness, and is also beneficial to improving the accuracy of the anti-drop performance detection of the motherboard. At the same time, it is applicable to the batch detection of the motherboard, and there will be no phenomena such as scratches and dirt on the surface of the motherboard when it falls.

[0019] 2. Through the set heating unit, the motherboard can be appropriately heated before being squeezed and stretched to simulate the high-temperature environment when the motherboard is working, which is beneficial to improving the accuracy of the extrusion and stretching detection of the motherboard.

[0020] 3. Through the set temperature measurement mechanism, the heat conductivity of the motherboard can be detected by using the heat source heated by the heating unit, and the possible defects such as extra holes inside the motherboard can be reflected through the heat conduction efficiency of the motherboard, further improving the accuracy of the anti-drop performance evaluation of the motherboard from the side.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] As Figures 1-5 shown, a computer hardware anti-drop performance detection device includes a box body 1 and a detection table 2 fixedly installed inside the box body 1. A controller 3 is installed on the outer side wall of the box body 1. A sealing trigger assembly 4 is installed on the box body 1. The sealing trigger assembly 4 includes a sealing cover plate 41 arranged above the box body 1. Electric push rods 42 are fixedly inserted on both sides of the bottom of the box body 1.

A proximity switch 43 is inserted into the end face of the sealing cover plate 41. The two electric push rods 42 and the proximity switch 43 are electrically connected to the controller 3. The proximity switch 43 detects whether the main board has been moved into the box body 1 through photoelectric induction.

[0029] Four supporting frustums 5 are respectively arranged at the four corners of the detection table 2. Installation grooves 6 are opened at the four corners of the top of the detection table 2, and a motor driving mechanism 7 is installed in each installation groove 6. The motor driving mechanism 7 is used to drive the supporting frustum 5 on the same side to rotate. Four pushing and pulling units 8 are all installed on the top of the corresponding supporting frustum 5. The pushing and pulling unit 8 is used to apply a pushing force and a pulling force to the main board. Each of the four pushing and pulling units 8 includes a side plate 81 fixedly installed on the top of the supporting frustum 5. A horizontal pushing electromagnetic push rod 82 is fixedly inserted into the side wall of the side plate 81. A movable block 83 is slidably connected to the end face of the supporting frustum 5, and the telescopic end of the horizontal pushing electromagnetic push rod 82 is fixedly connected to the side wall of the movable block 83.

The diameter of the positioning column 85 matches the diameter of the main board installation hole. The horizontal pushing electromagnetic push rod 82 is electrically connected to the controller 3.

Each displacement detection component 9 includes a mounting block 91 fixedly installed on the top of the supporting frustum 5, and the mounting block 91 is arranged on the side of the movable block 83 away from the side plate 81. An infrared ranging probe 92 is fixedly inserted into the side wall of the mounting block 91, and the infrared ranging probe 92 is used to detect the distance from the movable block 83. The infrared ranging probe 92 is electrically connected to the controller 3. The infrared ranging probe 92 can accurately measure the distance by emitting infrared rays and calculating the time required to receive the reflected infrared rays.

[0031] The heating unit 10 is installed at the center of the detection table 2. The heating unit 10 is used to heat the center of the main board. The heating unit 10 includes a circular hole 101 opened at the center of the detection table 2. A heating lamp 102 is installed inside the circular hole 101. The light-emitting surface of the heating lamp 102 faces upward. The heating lamp 102 is electrically connected to the controller 3. The heating lamp 102 can heat the main board from the bottom.

[0032] On one side of the side walls of the four vertical parts of the detection table 2, a temperature measuring mechanism 11 is provided. The temperature measuring mechanism 11 is used to detect the temperature of the side wall of the main board. Each temperature measuring mechanism 11 includes a set of support sleeves 111 fixedly installed on the inner wall of the box body 1, and the support sleeves 111 correspond to the top position of the detection table 2. A piston 112 is slidably connected inside each support sleeve 111. Two connecting rods 113 are fixedly installed on the side wall of the piston 112, and the two connecting rods 113 are fixedly connected to a pressing heat conduction plate 114 together. A plurality of uniformly distributed temperature detection probes 115 are installed on the side wall of the pressing heat conduction plate 114. The support sleeve 111 is communicated with the air outlet end of the temperature control unit 12. The temperature detection probe 115 is used to detect the temperature of the side wall of the main board. The temperature detection probe 115 is electrically connected to the controller 3. An elastic member 116 is fixedly arranged between each piston 112 and the inner wall of the box body 1. The temperature detection probe 115 can detect the temperature and feedback an electrical signal to the controller 3 when the temperature is not within the threshold range.

[0033] The temperature control unit 12 is installed at the bottom of the box body 1. The temperature control unit 12 is used to dissipate heat and cool the inside of the box body 1. The temperature control unit 12 includes a hot air blower 121 fixedly installed at the bottom of the box body 1. The air outlet end of the hot air blower 121 is communicated with the inside of the box body 1. An air hood 122 is arranged above the air outlet end of the hot air blower 121, and the air hood 122 is fixedly connected to the inner wall of the box body 1. A plurality of air holes 123 are opened on the end face of the air hood 122. A supply air pipe 124 is fixedly communicated with the side wall of each support sleeve 111, and each supply air pipe 124 is communicated with the inside of the air hood 122. The air outlet end of each supply air pipe 124 is arranged on the side of the piston 112 away from the detection table 2. A sealing component 13 is installed at the bottom of the detection table 2. The sealing component 13 is used to block each air hole 123. The hot air blower 121 is electrically connected to the controller 3. The hot air blower 121 can heat the inhaled air and convey the heated air to the inside of the air hood 122.

[0034] The sealing component 13 includes two vertical push electromagnetic push rods 131 fixedly installed at the bottom of the detection table 2, and a blocking plate 132 is fixedly connected to the telescopic ends of the two vertical push electromagnetic push rods 131 together. Each air hole 123 is arranged directly below the blocking plate 132, and the blocking plate 132 can block each air hole 123.

[0035] The operating principle of the present invention is described as follows: Initially, two electric push rods 42 position the sealing cover plate 41 0.5 meters above the box body 1. The completed main board is clamped and fixed by an external manipulator. The manipulator moves it inside the box body 1 according to the program and installs it on the detection table 2. At this time, each positioning post 85 passes through the mounting holes at the four corners of the main board (the mounting holes left at the four corners of the main board are for facilitating subsequent fixation with the chassis). When the manipulator moves the main board into the box body 1, the proximity switch 43 will detect the entry action of the main board. At this time, the proximity switch 43 will send an electrical signal to the controller 3. After 10 seconds (during this time period, the manipulator places the main board on the detection table 2 and leaves), the controller 3 will initiate a detection operation;

[0036] After the controller 3 starts the detection work, the controller 3 will first control the heating lamp 102 to work. The heating lamp 102 can heat the bottom of the main board, and the heating temperature is 65 °C. At the same time, the controller 3 will control the two vertical push electromagnetic push rods 131 to be energized. The two vertical push electromagnetic push rods 131 will push the plugging plate 132 downward and make the plugging plate 132 abut against the top of the air hood 122, so as to seal each air hole 123. Subsequently, the controller 3 starts the hot air blower 121. The hot air blower 121 will inhale the external air and transport it into the air hood 122. Since each air hole 123 is plugged, the air flow will enter each support sleeve 111 through each air supply pipe 124. Under the action of the increased air pressure, each piston 112 will move towards the detection table 2. After the hot air blower 121 works for 10 seconds, the controller 3 controls the hot air blower 121 to stop working, and at the same time controls the electric control valve at the air outlet end of the hot air blower 121 to close (this electric control valve is not shown in the figure, and it can control the on-off of the air outlet end of the hot air blower 121. After the electric control valve is closed, it can prevent the redundant air inside each support sleeve 111 from flowing back and escaping). At this time, each pressing heat conduction plate 114 abuts against the side wall of the main board. After the heating lamp 102 works for 1 minute, the controller 3 starts each temperature detection probe 115. When the temperature detection probe 115 detects that the current temperature is lower than or exceeds the threshold value, the temperature detection probe 115 will feedback an electric signal to the controller 3, which means that there are defects such as redundant holes inside the main board that affect the anti-drop performance. The controller 3 will alarm to prompt this information. Secondly, the position of the temperature detection probe 115 that alarms will be displayed on the display screen of the controller 3 to facilitate subsequent personnel to check (the threshold value for the temperature detection probe 115 to feedback the electric signal can be measured under the same conditions with a standard qualified main board). After 1 minute and 5 seconds, the controller 3 shuts down each temperature detection probe 115. At the same time, the controller 3 controls the two vertical push electromagnetic push rods 131 to be powered off and controls the electric control valve at the air outlet end of the hot air blower 121 to open. At this time, the redundant air inside each support sleeve 111 will flow back and be discharged through the air supply pipe 124. Under the action of the elastic member 116, each piston 112 will drive the pressing heat conduction plate 114 to move back to the reset position;

[0037] After the heating lamp 102 works for 1 minute and 5 seconds, the controller 3 controls the heating lamp 102 to stop working, and controls each horizontal push electromagnetic push rod 82 to perform a timed extension action. After the timed extension action ends, the controller 3 controls the infrared ranging probe 92 to work for 1 second, and after 1 second, controls the horizontal push electromagnetic push rod 82 to perform a timed retraction action. Then, it controls the infrared ranging probe 92 to work for 1 second at a fixed time again. When the horizontal push electromagnetic push rod 82 performs a timed extension action, each horizontal push electromagnetic push rod 82 will push the movable block 83 to move, and the movable block 83 will drive the positioning column 85 to move through the support column 84. The positioning column 85 is inserted into the mounting hole of the main board. Therefore, when the horizontal push electromagnetic push rods 82 on both sides perform an extension action, the main board will be subjected to an opposite extrusion force. Due to the certain elastic deformation ability of the main board, the main board will be in a slightly arched state. When the structural strength of the main board is not high or the toughness of the main board is poor, the degree of arching deformation of the main board will be too large or too small. At this time, the displacement distance of the movable block 83 will be too large or too small. Therefore, when the structural strength of the main board is not high or the toughness of the main board is poor, the infrared ranging probe 92 will detect that the displacement distance of the movable block 83 is too large or too small, and thus feedback an electrical signal to the controller 3. When the horizontal push electromagnetic push rod 82 performs a return action, the horizontal push electromagnetic push rod 82 will apply a tensile force to the main board through the positioning column 85. Similarly, when the anti-tensile performance of the main board is not good, the infrared ranging probe 92 will detect that the displacement distance of the movable block 83 is too large, and thus will also feedback an electrical signal to the controller 3. Therefore, when the horizontal push electromagnetic push rod 82 performs extrusion and stretching actions on the main board, by judging the displacement distance of the movable block 83, parameters such as the toughness, structural strength, and anti-tensile performance of the main board can be judged. By judging parameters such as the toughness, structural strength, and anti-tensile performance of the main board, the anti-drop performance of the main board can be reflected from the side (wherein, the time and pushing force magnitude of the timed extension action and the timed return action performed by the horizontal push electromagnetic push rod 82 are measured under the same conditions with a standard qualified main board);

[0038] After the infrared distance measurement probe 92 has performed two distance measurement operations, the controller 3 controls the four motor drive mechanisms 7 to operate (the motor drive mechanism 7 includes components such as a stepping motor, a drive shaft, and bearings). The motor drive mechanism 7 can drive the support turntable 5 to rotate by 10°. Then, the controller 3 controls the horizontal push electromagnetic push rod 82 and the infrared distance measurement probe 92 to repeat the above detection work in a cycle. When the support turntable 5 rotates by 90°, the detection work on the main board ends. After the detection of the current main board ends, the controller 3 controls the electric push rod 42 to perform a timed extension action to reset the sealing cover plate 41 upward. Subsequently, the controller 3 controls the hot air blower 121 to operate. The hot air blower 121 heats the external air, and the heating temperature is 40°C. Until the next main board is placed on the detection table 2, the hot air blower 121 stops working. By outputting hot air at 40°C from the hot air blower 121, the heat heated by the heating lamp 102 during the previous main board detection can be dissipated in time, keeping the inside of the box 1 at a stable temperature of 40°C, thereby avoiding affecting the accuracy of the detection of the heat conduction efficiency of the main board by the temperature detection probe 115 due to temperature differences;

[0039] Among them, when the infrared distance measurement probe 92 detects that the distance exceeds the standard, and when the temperature detection probe 115 detects that the temperature is not within the threshold, the controller 3 will alarm. After the controller 3 receives the alarm signals fed back by the infrared distance measurement probe 92 and the temperature detection probe 115, the controller 3 sends an instruction to the control end of the external automatic manipulator, and the external automatic manipulator clamps, fixes, and takes out the main board and places it at a specified position (the placement position is distinguished from the qualified product placement area).

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
