Description

Technical Field

[0001] This utility model relates to the field of motherboard detection and positioning technology, specifically a motherboard detection and positioning structure. Background Technology

[0002] Motherboard testing is a crucial step in ensuring the normal operation of a computer motherboard. It involves a series of technical methods to comprehensively diagnose the motherboard hardware and functions. During the testing process, the motherboard needs to be limited by a positioning structure to ensure the smooth completion of the testing operation.

[0003] Currently, the motherboard detection and positioning structure uses a positioning platform to place the motherboard, and then uses an electric push rod to contact the side of the motherboard to position it by the contact force. However, during the process of placing the motherboard on the top of the positioning platform, sometimes the side of the motherboard with interfaces is directly facing the contact head due to different placement positions. This can easily cause damage to the interfaces during subsequent positioning, increasing costs. Therefore, there is a need to provide a positioning structure that can solve the above-mentioned drawbacks and improve the efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a motherboard detection and positioning structure to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a motherboard detection and positioning structure, comprising:

[0006] The detection and positioning component includes a positioning base and a movable motor located in the middle of the positioning base. A support plate is provided on the upper part of the inner side of the positioning base. The upper part of the output end of the movable motor extends out of the support plate and is fixed with a positioning platform. A positioning post is fitted on the upper corner of the positioning platform. The positioning post passes through the opening at the corner of the main board. Hole blocks are symmetrically provided on the upper ends of both sides of the positioning base. An electric push rod is connected through the upper part of the hole block. A rubber head is fitted on the output end of the electric push rod, and an infrared ranging sensor is fitted in the middle cavity of the rubber head.

[0007] Furthermore, the output terminal of the infrared ranging sensor is electrically connected to a wire that extends into the interior of the rubber head, and the rubber head abuts against the opposite sides of the main board.

[0008] Furthermore, a positioning block is fixed to the inner side of the lower end of the hole block, and the positioning block is threadedly fixed to the positioning seat by a positioning bolt that passes through the middle.

[0009] Furthermore, it also includes a motor assembly / disassembly assembly, which includes a cavity extending through the middle of the positioning seat and a guide groove located at the bottom center of the cavity. A guide block is slidably connected in the guide groove, and an mounting plate is fixed to the upper end of the guide block. The groove in the middle of the upper end of the mounting plate abuts against the lower end of the movable motor.

[0010] Furthermore, a connecting ring is fixed to the lower part of the outer surface of the movable motor, and the connecting ring is threaded to the mounting plate by connecting bolts that pass through the middle at equal intervals.

[0011] Furthermore, limit blocks are fixed at the rear of both sides of the guide block, and limit grooves are opened on opposite sides of the inner wall of the guide groove, with the limit blocks slidably connected in the limit grooves.

[0012] Furthermore, a top cylinder is fixed at the bottom end of the cavity, and the output end of the top cylinder is fitted with the bottom end of the support plate. A sealing plate is fitted on the outer side of the inner wall of the cavity.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes a positioning platform with positioning posts at the upper corners, through openings at the corners of the motherboard, to perform initial positioning, preventing deviation in the sound emission position during subsequent secondary positioning. During secondary positioning of the motherboard via a rubber head using an electric push rod, an infrared distance sensor detects the distance between the platform and the motherboard side. A larger distance to the motherboard side and a smaller distance to the interface on the motherboard side panel indicate an incorrect positioning orientation. An external control unit then activates a moving motor to actively adjust the positioning platform's position, preventing interface damage, reducing costs, and simplifying use.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 As shown, this utility model is a motherboard detection and positioning structure, comprising:

[0026] The detection and positioning component includes a positioning base 11 and a movable motor 12 located in the middle of the positioning base 11. A support plate 111 is provided on the upper part of the inner side of the positioning base 11. The upper part of the output end of the movable motor 12 extends out of the support plate 111 and is fixed with a positioning platform 13. A positioning post 14 is sleeved on the upper corner of the positioning platform 13. The positioning post 14 passes through the opening at the corner of the main board. Hole blocks 15 are symmetrically provided on the upper ends of both sides of the positioning base 11. An electric push rod 16 is connected through the upper part of the hole block 15. A rubber head 17 is sleeved on the output end of the electric push rod 16. An infrared ranging sensor 18 is sleeved in the middle cavity 21 of the rubber head 17.

[0027] The positioning base 11 provides a structural installation environment. The support plate 111 supports the positioning platform 13. Using the positioning platform 13 in conjunction with the positioning column 14, the motherboard to be tested can be initially positioned. The hole block 15 is used to install and fix the electric push rod 16. The controlled electric push rod 16 uses the rubber head 17 to act on the opposite sides of the motherboard to perform secondary positioning of the motherboard. The infrared distance sensor 18 is model GP2Y0A21YK0F. By detecting the distance between the sensor and the side of the motherboard, it can determine whether the motherboard is placed incorrectly, avoid damage to the interfaces on the motherboard by squeezing, and reduce costs.

[0028] The output terminal of the infrared ranging sensor 18 is electrically connected to a wire 19, which extends out of the rubber head 17, and the rubber head 17 is in contact with the opposite sides of the main board.

[0029] Conductor 19 is used for both power supply and data transmission.

[0030] A positioning block 110 is fixed to the inner side of the lower end of the hole block 15, and the positioning block 110 is threadedly fixed to the positioning seat 11 by a positioning bolt that passes through the middle.

[0031] The positioning bolts fix the positioning ring, and the fixed positioning ring is used to fix the hole block 15.

[0032] Working principle: During the detection and positioning of the motherboard, the motherboard is placed on the upper surface of the positioning platform 13, and the positioning post 14 is inserted through the corner opening of the motherboard to perform preliminary structural positioning. At this time, before the operation of the electric push rod 16, the infrared ranging sensor 18 in the rubber head 17 detects the distance between the motherboard and the side. When there are no protruding parts such as interfaces on the side of the motherboard, the detected distance is larger, and vice versa. Then, the external control terminal operates the movable motor 12 to change the position of the positioning platform 13. Then, the controlled electric push rod 16 is used to act on the rubber head 17 and the side of the motherboard to perform secondary positioning.

[0033] This solution ensures the correct structural positioning for motherboard testing while preventing interface damage, reducing costs, and facilitating use.

[0034] Please see Figure 1-5 As shown, this embodiment is based on the above embodiment:

[0035] It also includes a motor assembly and disassembly assembly, which includes a cavity 21 that runs through the middle of the positioning seat 11 and a guide groove 22 that runs through the bottom middle of the cavity 21. A guide block 23 is slidably connected in the guide groove 22, and a mounting plate 24 is fixed to the upper end of the guide block 23. The groove in the middle of the upper end of the mounting plate 24 abuts against the lower end of the movable motor 12.

[0036] The cavity 21 provides an installation environment. The mounting plate 24 is fixed by the guide block 23, and the structure is initially fixed by the contact between the groove and the movable motor 12. The sliding of the guide block 23 in the guide groove 22 allows the movable motor 12 to move to multiple positions, so as to facilitate removal and disassembly from the cavity 21.

[0037] A connecting ring 25 is fixed to the lower part of the outer surface of the movable motor 12, and the connecting ring 25 is threadedly fixed to the mounting plate 24 by connecting bolts that pass through the middle at equal intervals.

[0038] The connecting bolts fix the connecting ring 25, and the fixed connecting ring 25 further fixes the movable motor 12.

[0039] Limiting blocks 29 are fixed to the rear of both sides of the guide block 23, and limiting grooves 28 are opened on opposite sides of the inner wall of the guide groove 22. The limiting blocks 29 are slidably connected in the limiting grooves 28.

[0040] The sliding of the limiting block 29 within the limiting groove 28 provides secondary position guidance for the movable motor 12 entering and exiting the cavity 21, and the position of the movable motor 12 can be limited by the mutual contact between the two.

[0041] A top cylinder 26 is fixed at the bottom end inside the cavity 21, and the output end of the top cylinder 26 is fitted with the bottom end of the support plate 111. A sealing plate 27 is fitted on the outer side of the inner wall of the cavity 21.

[0042] The top cylinder 26 supports the support plate 111 and allows for height adjustment, which in turn allows the movable motor 12 to move out of the cavity 21. The sealing plate 27 shields the cavity 21 and isolates and protects the internal structure.

[0043] Working principle: During the installation and use of the movable motor 12, the support plate 111 is first raised by the controlled top cylinder 26. At this time, an inward pushing force is applied to the movable motor 12. Through the sliding of the guide block 23 in the guide groove 22 and the sliding of the limiting block 29 in the limiting groove 28, the movable motor 12 moves into the cavity 21 until the limiting block 29 abuts against the inner wall of the limiting groove 28, that is, the movable motor 12 moves to the designated position, that is, to the center position. Then, the support plate 111 is moved down by the controlled top cylinder 26, so that the upper part of the output end of the movable motor 12 moves out of the support plate 111. Subsequently, it can be fixedly installed with the positioning table 13. Then, the sealing plate 27 is sleeved on the inner wall of the cavity 21. Relying on the abutment between it and the guide block 23, the secondary fixation of the movable motor 12 structure is ensured. When disassembling, the reverse operation is applied.

[0044] This solution allows for easy removal of the movable motor 12 located deep inside for disassembly and assembly, saving time and effort and making it convenient to use.
