Description

Technical Field

[0001] This utility model relates to the technical field of motherboard quality inspection, specifically a turntable for computer motherboard quality inspection. Background Technology

[0002] The motherboard, also called the mainboard, system board, or motherboard, is one of the most basic and important components of a computer. It is generally a rectangular circuit board that houses the main circuitry of the computer, typically including a BIOS chip, I / O control chip, keyboard and front panel control switch interfaces, indicator light connectors, expansion slots, and DC power supply connectors for the motherboard and expansion cards. During quality inspection, the computer motherboard needs to be supported on a turntable to facilitate detailed testing by quality control personnel.

[0003] Currently, most turntables are usually mounted on the workbench with bolts. However, the turntable cannot accurately position the threaded hole and the hole position during installation, which has the following disadvantages: the hole position and threaded hole need to be frequently adjusted during the installation of the turntable, which increases the installation difficulty and reduces the convenience and efficiency of turntable installation. Utility Model Content

[0004] The purpose of this invention is to provide a turntable for quality inspection of computer motherboards, in order to solve the problem that when installing the turntable, it is necessary to frequently adjust the alignment of the hole and the threaded hole, which increases the difficulty of installation and reduces the convenience and efficiency of turntable installation.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a turntable for computer motherboard quality inspection, comprising a workbench, the workbench being movably disposed above a base, a mounting groove being provided on the top surface of the workbench, a mounting plate being detachably disposed inside the mounting groove, a rotating disk being rotatably disposed above the mounting plate, two first threaded holes being provided on the top surface of the mounting plate, two second threaded holes being provided on the bottom surface of the mounting groove, bolts being threadedly connected to the two second threaded holes respectively, the threaded ends of the two bolts being threadedly connected to the two first threaded holes respectively, positioning blocks being fixed on the front and rear sides of the mounting plate respectively, and positioning grooves being provided on the front and rear sides of the inner wall of the mounting groove respectively, the two positioning grooves respectively positioning the two positioning blocks.

[0006] Preferably, the top surface of the mounting plate is provided with a fixing groove, a bearing is fixed inside the fixing groove, a rotating shaft is fixed to the inner wall of the inner ring of the bearing, and the top end of the rotating shaft is fixedly connected to the bottom end of the rotating plate.

[0007] Preferably, an anti-slip pad is fixed to the top of the rotating disk.

[0008] Preferably, the top surface of the base is provided with a connecting groove, and an electric push rod is fixed inside the connecting groove. One end of the telescopic rod of the electric push rod is fixedly connected to the inner top surface of the workbench.

[0009] Preferably, the top surface of the base has two limiting grooves, and limiting posts are slidably inserted into the two limiting grooves respectively. The top ends of the two limiting posts are fixedly connected to the bottom surface of the workbench.

[0010] Preferably, the thickness of the anti-slip mat is 2cm.

[0011] Compared with existing technologies, a computer motherboard quality inspection turntable that adopts the above technical solution has the following beneficial effects:

[0012] 1. In use, when the operator needs to install the rotating disk onto the workbench, they first precisely align the positioning block on the mounting disk with the positioning slot to ensure that the mounting disk can be smoothly and stably placed into the mounting slot. Through the auxiliary positioning function of the positioning block and the positioning slot, the first threaded hole and the second threaded hole can quickly and accurately align. Then, the operator only needs to rotate the bolt to connect its threaded end sequentially with the internal threads of the second threaded hole and the first threaded hole, thus completing the installation of the mounting disk and the rotating disk. The operator can then place the computer motherboard on the rotating disk for quality inspection. Conversely, when it is necessary to disassemble the rotating disk, the operator only needs to rotate the bolt in the opposite direction to move it away from the inside of the first threaded hole to complete the disassembly. The combined use of the mounting disk, bolts, positioning block, and positioning slot simplifies the installation and disassembly process, improving the convenience and efficiency of rotating disk installation.

[0013] Second, during use, the cooperation between the bearings and the rotating shaft enables the turntable to rotate smoothly and flexibly, which not only improves the rotational accuracy and stability of the turntable but also extends its service life. Anti-slip pads prevent items such as computer motherboards placed on the turntable from sliding or falling during rotation, ensuring the stability and safety of these items. By activating the electric push rod, the worktable can be moved up and down for adjustment, thereby adjusting the height of the turntable. This allows operators to adjust the height of the turntable as needed to adapt to different work scenarios and requirements, improving the flexibility and adaptability of the worktable and turntable.

[0014] Thirdly, during use, the combination of the limiting groove and the limiting column facilitates limiting the movement of the worktable during lifting and lowering, preventing the worktable from shifting or shaking during the process and ensuring the stability and accuracy of the worktable and the rotating plate during lifting. By setting the thickness of the anti-slip pad to 2cm, sufficient anti-slip effect is ensured while avoiding the inconvenience of installation and waste of space caused by excessive thickness.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a turntable for inspecting computer motherboards includes a workbench 1, which is movably mounted above a base 2. A mounting groove 3 is formed on the top surface of the workbench 1. A mounting plate 4 is detachably mounted inside the mounting groove 3. A rotating disk 5 is rotatably mounted above the mounting plate 4. Two first threaded holes 6 are formed on the top surface of the mounting plate 4. Two second threaded holes 7 are formed on the bottom surface of the mounting groove 3. Bolts 8 are threaded into the two second threaded holes 7, and the threaded ends of the two bolts 8 are threaded into the two first threaded holes 6. Positioning blocks 9 are fixed to the front and rear sides of the mounting plate 4. Positioning grooves 10 are formed on the front and rear sides of the inner wall of the mounting groove 3, and the two positioning grooves 10 respectively position the two positioning blocks 9.

[0022] In use, when the operator needs to install the rotating disk 5 onto the workbench 1, they first precisely align the positioning block 9 on the mounting disk 4 with the positioning groove 10, ensuring that the mounting disk 4 can be smoothly and stably placed into the interior of the mounting groove 3. Through the auxiliary positioning function of the positioning block 9 and the positioning groove 10, the first threaded hole 6 and the second threaded hole 7 can quickly and accurately align. Then, the operator only needs to rotate the bolt 8 so that its threaded end sequentially connects with the internal threads of the second threaded hole 7 and the first threaded hole 6, thus completing the installation of the mounting disk 4 and the rotating disk 5. The operator can then place the computer motherboard on the rotating disk 5 for quality inspection. Conversely, when it is necessary to disassemble the rotating disk 5, the operator only needs to rotate the bolt 8 in the opposite direction, moving it away from the interior of the first threaded hole 6, to complete the disassembly. The coordinated use of the mounting disk 4, bolt 8, positioning block 9, and positioning groove 10 simplifies the installation and disassembly process, improving the convenience and efficiency of installing the rotating disk 5.

[0023] like Figures 1-3 As shown, a fixing groove 11 is provided on the top surface of the mounting plate 4. A bearing 12 is fixed inside the fixing groove 11. A rotating shaft 13 is fixed on the inner wall of the inner ring of the bearing 12. The top end of the rotating shaft 13 is fixedly connected to the bottom end of the rotating plate 5.

[0024] In use, the cooperation between bearing 12 and rotating shaft 13 enables the rotating disk 5 to rotate smoothly and flexibly, which not only improves the rotation accuracy and stability of the rotating disk 5, but also extends its service life.

[0025] like Figures 1-4 As shown, an anti-slip pad 14 is fixed to the top of the rotating disk 5, and a connecting groove 15 is provided on the top surface of the base 2. An electric push rod 16 is fixed inside the connecting groove 15, and one end of the telescopic rod of the electric push rod 16 is fixedly connected to the inner top surface of the workbench 1.

[0026] During use, the anti-slip pad 14 helps prevent items such as computer motherboards placed on the rotating disk 5 from sliding or falling during rotation, ensuring the stability and safety of the items during rotation. By activating the electric push rod 16, the workbench 1 can be moved up and down for adjustment, thereby adjusting the height of the rotating disk 5. This allows operators to adjust the height of the rotating disk 5 as needed to adapt to different work scenarios and requirements, improving the flexibility and adaptability of the workbench 1 and the rotating disk 5.

[0027] like Figures 1-4 As shown, the top surface of the base 2 has two limiting grooves 17, and the limiting posts 18 are slidably inserted into the two limiting grooves 17 respectively. The tops of the two limiting posts 18 are fixedly connected to the bottom surface of the workbench 1 respectively. The thickness of the anti-slip pad 14 is 2cm.

[0028] In use, the cooperation of the limiting groove 17 and the limiting post 18 facilitates the limiting of the worktable 1 during lifting and lowering, preventing the worktable 1 from shifting or shaking during the lifting process, and ensuring the stability and accuracy of the worktable 1 and the rotating disk 5 during the lifting process. By setting the thickness of the anti-slip pad 14 to 2cm, sufficient anti-slip effect is ensured while avoiding the inconvenience of installation and waste of space caused by excessive thickness.
