Description

Technical Field

[0001] The present invention relates to the technical field of computer technology shell strength detection, and in particular to a computer technology shell strength detection device and detection system. Background Art

[0002] The content of computer technology is very broad and can be roughly divided into several aspects such as computer system technology, computer device technology, computer component technology and computer assembly technology. Computer technology includes the basic principles of calculation methods and arithmetic unit design, instruction system, central processing unit design, pipeline principles and their application in CPU design, storage system, bus and input and output.

[0003] Computers are mainly used in computer technology. When producing computers, it is necessary to perform strength testing on the computer casing to ensure that the computer casing can meet the use standards. Nowadays, when performing strength testing on the computer casing, a heavy object is generally used to press down on the computer casing to observe whether the casing of the computer casing is deformed, and a pressure sensor is used for testing. However, many heat dissipation vents are often provided on the computer casing to ensure heat dissipation performance. The heat dissipation vents cause gaps in the computer casing, and the gaps will cause the strength of the computer casing to be weakened, which will interfere with the accuracy of the test results during testing. The computer casing is generally clamped and fixed by a fixture to prevent the computer casing from shifting. However, the fixture is generally not able to shift flexibly, resulting in the inability to flexibly adjust the position of the computer casing. When the impact component shifts, the shifting time will also cause the detection work to be suspended, resulting in the inability to continuously detect multiple points of the computer casing, resulting in low detection efficiency.

[0016] Compared with the existing technology, the advantages of the computer technology shell strength detection device and detection system are:

[0017] 1. Place the computer case to be tested vertically between two groups of L-shaped clamps, and press the roller under the action of gravity. The two groups of movable plates rotate clockwise with the horizontal axis 2 as the central axis. With the cooperation of the transmission belt 1, the horizontal axis 1, and the movable block, one group of L-shaped clamps rotates counterclockwise with the hinge of one group of vertical plates as the central axis, and the other group of L-shaped clamps rotates clockwise with the hinge of the other group of vertical plates as the central axis, so that the upper ends of the two groups of L-shaped clamps are close to each other, the two ends of the computer case are clamped and fixed, and the position of the computer case is automatically and preliminarily fixed. With the cooperation of the transmission belt 2 in the auxiliary mechanism, the two groups of rotating shafts 1 and the two groups of gears 1 rotate clockwise at the same time, and cooperate with each group of tooth grooves to drive The two sets of sliding plates move downward, and cooperate with the connecting rod 1 to make the limit plate move toward the direction of the bearing shell, and further clamp and fix the position of the computer shell. When the computer shell moves downward to the upper end surface of the bearing shell, the groups of plug plates on the limit plate are correspondingly inserted into the groups of heat dissipation ports on the computer shell to fill and block the groups of heat dissipation ports, which leads to inaccurate detection results and avoids displacement during the subsequent detection process. Through the above operation, not only can the gravity of the computer shell be used to automatically clamp and fix the four sides of the computer shell, making the clamping and fixing more convenient and the fixing effect better, but also the heat dissipation ports can be filled and blocked at the same time, avoiding the strength of the computer shell being affected by the gap in the heat dissipation port, resulting in inaccurate detection results.

[0018] 2. When the collar moves down to perform impact detection on the computer housing, the cross plate moves down at the same time, and cooperates with the connecting rod, ramp block and rack in the traction mechanism to drive gear 2 to rotate 180° counterclockwise, so that a part of the traction rope falls off the winding roller, and under the action of the gravity of the weight block and the sliding block, the T-shaped limit block can be moved down inside the connection shell in cooperation with the limit groove, and the part of the traction rope that falls off the winding roller can be pulled into the connection shell, and the position of the displaced sliding block can be fixed by the reset spring 2 and the two sets of trapezoidal blocks in cooperation with the two sets of slots, so that the position of the traction rope after pulling is fixed, so that the length of the traction rope outside the connection shell is reduced. At this time, the impact head moves up, and similarly, the winding roller rotates counterclockwise to reel in the reduced length of the traction rope, so that the traction rope is transmitted along the guide roller, pulling the load-bearing shell and the computer shell clamped and fixed thereon to automatically move a certain distance, so that the position of the upper surface of the computer shell corresponding to the impact head can be changed, so that the subsequent downward-moving impact head can perform impact detection on another position of the upper surface of the computer shell, and the above operation is repeated, so that after each impact detection, the computer shell can automatically move a certain distance, and continuous multi-point impact detection of the computer shell is realized, thereby improving the detection efficiency and the accuracy of the detection results;

[0019] 3. When one end of the plug-in board contacts the surface of the computer shell, if there is a corresponding heat dissipation port, it is automatically inserted. If there is no heat dissipation port at the corresponding position, each group of spring pieces is compressed accordingly, and under the action of the elastic force of the spring pieces, the plug-in board moves toward the outer wall of the computer shell, and cooperates with the plug-in board on the other side of the computer shell in the horizontal position, so as to further limit the position of the computer shell, and the applicability is further improved. When the impact head presses down to hit the computer shell, when the computer shell moves downward briefly, the limit plate clamped on the computer shell can move downward accordingly through the T-shaped block and the T-shaped vertical groove, which will not hinder the downward movement of the computer shell, thereby avoiding affecting the accuracy of the computer shell detection.

[0020] In summary, the present invention can not only use the gravity of the computer case to automatically clamp and fix the four sides of the computer case by setting an auxiliary mechanism to cooperate with the movable block and the L-shaped clamp, making the clamping and fixing more convenient and the fixing effect better, but also can fill the heat dissipation port at the same time to avoid the strength of the computer case being affected by the gap in the heat dissipation port, resulting in inaccurate detection results, and through the traction mechanism, it is achieved that after each impact detection of the impact head, the clamped and fixed computer case can automatically move laterally for a distance, thereby realizing continuous horizontal multi-point impact detection of the computer case, thereby improving the detection efficiency and the accuracy of the detection results.

When the reciprocating screw 5 rotates, the collar 6 can move vertically back and forth along the reciprocating screw 5 with the cooperation of the thread.

[0047] Specifically, when the horizontal axis 15 rotates clockwise, in cooperation with the transmission belt 28 in the auxiliary mechanism, the two sets of rotating shafts 1 29 can be driven to rotate clockwise at the same time, thereby driving the two sets of gears 1 36 to rotate clockwise at the same time, and in cooperation with each set of tooth grooves, the two sets of sliding plates 30 can be driven to move downward through the T-shaped block 2 38 and the T-shaped slide groove 37, and one end of the connecting rod 1 31 follows the sliding plate 30 to move downward and rotate, and the other end of the connecting rod 1 31 rotates with the side plate 32, and can drive the side plate 32 and the limiting plate 33 to move along the support rod 66 toward the direction of the bearing shell 11. When the computer shell 3 moves down to the upper surface of the bearing shell 11, the groups of plug plates 34 on the limiting plate 33 are correspondingly inserted into the groups of heat dissipation ports 12 on the computer shell 3 to fill the groups of heat dissipation ports 12, so as to avoid the strength of the computer shell 3 being affected by the gaps in the heat dissipation ports 12, resulting in inaccurate detection results, and the position of the computer shell 3 can be further clamped and fixed to avoid subsequent displacement during the detection process;

[0048] After fixing the position of the computer housing 3 and plugging the heat dissipation port 12 on the computer housing 3, the reciprocating screw 5 can be driven to rotate by the motor, thereby driving the ring 6 to move downward through the cross plate 8 and the slide rod 9, thereby driving the impact head 7 connected by the connecting rod 64 and the circular plate 65 to move downward, and performing a knock test on the computer housing 3. During this process, the pressure sensor 18 detects the pressure on the computer housing 3 in real time.

[0049] The model of the pressure sensor 18 is HTL-01.

The two sets of fixed plates 44 are movably mounted between them. The movable shaft 49 is movably connected to the outer wall of the movable shaft 49, and a winding roller 46 is fixedly connected to the outer wall of the winding roller 46. A traction rope 47 is wound around the outer side of the winding roller 46. The bottom end of the connecting rod 40 is movably connected to the roller 42. A connecting shaft 60 is movably connected to the outer wall of one set of fixed plates 44, and one end of the connecting shaft 60 is fixedly connected to the movable shaft 49. A gear 2 48 is fixedly installed on the outer wall of the connecting shaft 60. A rack 43 is fixedly connected to the bottom surface of the ramp block 41, and the rack 43 and the gear 2 48 are meshed with each other. A connecting shell 50 is fixedly connected to the outer wall of the movable shaft 49 and located between the fixed plate 44 and the winding roller 46. A sliding block 52 is inserted into the connecting shell 50, and a limiting groove is provided on the outer wall of the connecting shell 50. A T-shaped limiting block 59 is inserted into the limiting groove, and one end of the T-shaped limiting block 59 is fixedly connected to the sliding block 52. A weighting block 53 is fixedly installed on the upper end surface of the sliding block 52. Contraction grooves 67 are provided on both outer walls of the sliding block 52. Trapezoidal clamping blocks 54 are inserted into both sets of contraction grooves 67. Several sets of clamping grooves 55 are provided on both inner walls of the connecting shell 50, and the several sets of clamping grooves 55 are matched with the trapezoidal clamping blocks 54. A clamping block 53 is installed between one end of the trapezoidal clamping block 54 and the inner wall of the contraction groove 67. Reset spring 2 69, two groups of short grooves 56 are penetrated through the outer wall of the sliding block 52, and toggle blocks 57 are inserted inside the two groups of short grooves 56, and one end of the two groups of toggle blocks 57 are respectively fixedly connected to the two groups of trapezoidal blocks 54, a through hole 1 is penetrated through the outer wall of the sliding block 52, and a through hole 1 is penetrated through the outer wall of the connecting shell 50. One end of the traction rope 47 passes through the two groups of through holes 1 and the through hole 2 is arranged outside the connecting shell 50, one end of the traction rope 47 is fixedly connected to the circular block 51, and the circular block 51 is fixedly connected to the connecting shell 50, and the other end of the traction rope 47 passes around the guide roller 45 and is fixedly connected to the bearing plate 10.

[0051] Specifically, when the collar 6 moves downward to perform impact detection on the computer housing 3, the horizontal plate 8 moves downward at the same time, driving the connecting rod 40 in the traction mechanism to move downward, and at the same time, the roller 42 installed at the bottom end of the connecting rod 40 moves along the inclined surface of the ramp block 41, so that the ramp block 41 can move horizontally through the long rod 61 and the limit sleeve 62, and the rack 43 moves horizontally with the ramp block 41, which can drive the gear 2 48 to rotate 180° counterclockwise (please refer to Fig.10), thereby driving the movable shaft 49 connected by the connecting shaft 60 to rotate 180° counterclockwise (the guide roller 45 is on the left side), and the winding roller 46 rotates counterclockwise with the movable shaft 49, so that a part of the traction rope 47 can fall off the winding roller 46, and at this time the connecting shell 50 rotates 180° with the movable shaft 49 as the central axis. At this time, under the weight of the weight block 53, the weight of the sliding block 52 is increased, so that the sliding block 52 can easily move downward inside the connecting shell 50 through the T-shaped limit block 59 and the limit groove under the action of gravity. In this process, the two groups of trapezoidal blocks 54 follow the sliding block 52 to move downward, and the inclined surface of the trapezoidal block 54 moves along the inner wall of the groove 55. Under the continuous drive of the sliding block 52, the trapezoidal block One end of 54 can be moved out from the inside of the card slot 55 and contracted into the contraction slot 67, so that the return spring 2 69 is compressed, thereby driving the part of the traction rope 47 inserted in the perforation 1 and the perforation 2 to move downward, so that the part of the traction rope 47 located outside the connection shell 50 is pulled into the connection shell 50, thereby pulling the part of the traction rope 47 that falls off the winding roller 46 into the connection shell 50. After the pulling is completed, under the action of the elastic force of the return spring 2 69, one end of the two groups of trapezoidal card blocks 54 can be driven to re-enter the corresponding two groups of card slots 55, fix the position of the displaced sliding block 52, and fix the position of the pulled traction rope 47. At this time, the length of the traction rope 47 outside the connection shell 50 is reduced;

[0052] When the impact head 7 completes the impact on the computer housing 3 and moves upward, the connecting rod 40 moves upward in the same way, releasing the downward pressure on the ramp block 41. Under the action of the elastic force of the supporting spring 4, the limiting sleeve 62 can be driven to move to the initial position, so that the rack 43 drives the gear 2 48 to rotate counterclockwise, thereby driving the winding roller 46 to rotate counterclockwise, and winding the traction rope 47 after the reduced length is wound up, so that the traction rope 47 is transmitted along the guide roller 45, pulling the bearing plate 10 to move a certain distance through the movable wheel 63 to cooperate with the track groove, thereby driving the bearing shell 11 and the computer housing 3 to automatically move a certain distance, so that the position of the upper end surface of the computer housing 3 corresponding to the impact head 7 can be changed, so that the subsequent downward-moving impact head 7 can impact the upper end surface of the computer housing 3 The computer housing 3 is automatically moved for a certain distance after each impact detection, and the impact detection of the computer housing 3 at multiple points is realized continuously, thereby improving the detection efficiency and the accuracy of the detection result. When the sliding block 52 falls to the bottom of the connecting shell 50, after the auxiliary displacement detection of the computer housing 3 is completed, the two groups of toggle blocks 57 can be moved along the short groove 56 and approach each other, which can drive one end of the two groups of trapezoidal blocks 54 to move out of the two groups of slots 55, release the limit of the sliding block 52, and then move the sliding block 52 to the initial position. Similarly, the trapezoidal block 54 and the reset spring 69 cooperate with the slot 55 to fix and reset it, so that it can be put into the next detection work.
