Description

Technical Field

[0001] This utility model relates to the field of motherboard testing technology, specifically a centralized power supply device for motherboard testing. Background Technology

[0002] A centralized power-on testing device for motherboards is a device used to test the power-on performance of motherboards. It can improve testing efficiency and accuracy, and ensure motherboard quality. It is commonly used in electronics manufacturing and related industries.

[0003] In existing technologies, suction cups are typically used to hold the motherboard in place during testing to prevent damage. However, existing suction cups usually have a smooth, circular structure. But the motherboard surface often has component protrusions and pad height differences. The smooth edges cannot fit into tiny gaps, easily forming air leakage channels, which leads to poor adhesion to the motherboard. During testing, the motherboard is prone to displacement, thus affecting the test results. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a centralized power-on device for motherboard detection, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a centralized power-on device for motherboard detection, comprising:

[0006] The detection assembly includes a support base, a main board body, an L-shaped rod, a hydraulic cylinder, and a detection head. The main board body is located on the top of the support base. One end of the top of the support base is fixedly connected to the L-shaped rod, and the other end of the L-shaped rod is fixedly connected to the hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected to the detection head.

[0007] The high-efficiency protective fixing component includes a rectangular box, a rectangular rubber ring, and rubber particles. The rectangular box is fixedly connected to the top of the support base, the rectangular rubber ring is movably connected to the top of the rectangular box, the rubber particles are fixedly connected to the top of the rectangular rubber ring, and the rubber particles are movably connected to the top of the motherboard body.

[0008] Furthermore, the rectangular rubber rings are equidistantly distributed on the rectangular box.

[0009] Furthermore, the rubber particles are arranged in a structure that is narrow at the top and wide at the bottom, and a V-shaped gap is formed between the rubber particles.

[0010] Furthermore, the high-efficiency protective fixing component also includes a rectangular ventilation slot, with the rectangular box having a through-hole rectangular ventilation slot.

[0011] Furthermore, the high-efficiency protective fixing component also includes a receiving pipe and an air intake machine, with one end of the receiving pipe fixedly inserted at the front end of the rectangular box, and the other end of the receiving pipe fixedly connected to the air intake machine.

[0012] Furthermore, it also includes a convenient replacement component, which includes a slot. The rectangular box has a slot located on both sides of the rectangular rubber ring.

[0013] Furthermore, the convenient replacement component also includes a magnetic strip and an iron block. The magnetic strip is fixedly installed in the slot, the iron blocks are fixedly bonded to both sides of the rectangular rubber ring, the iron blocks are movably connected in the slot, and the magnetic strip is magnetically connected to the iron blocks.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the rubber granules are designed with a narrow top and a wide bottom, forming a V-shaped gap between them. This design allows them to fit into uneven areas on the motherboard surface, such as component protrusions and differences in soldering height. By embedding into tiny gaps, they prevent air leakage channels, effectively improve the adsorption effect on the motherboard, and prevent displacement of the motherboard during testing, thereby ensuring the accuracy of the test results.

[0016] Based on the aforementioned beneficial effects, when the rectangular rubber ring is damaged, the damaged rectangular rubber ring is pulled upwards. At this time, the iron block disengages from the magnetic strip and the slot. Then, a new rectangular rubber ring is taken and installed. Thus, the damaged part can be replaced individually without replacing the whole thing, saving maintenance costs and improving the convenience and economy of maintenance. Attached Figure Description

[0029] Please see Figure 1-5 As shown, this utility model is a centralized power-on device for motherboard detection, comprising:

[0030] The detection assembly includes a support base 101, a main board body 102, an L-shaped rod 103, a hydraulic cylinder 104, and a detection head 105. The main board body 102 is located on the top of the support base 101. The L-shaped rod 103 is fixedly connected to one end of the top of the support base 101, and the hydraulic cylinder 104 is fixedly connected to the other end of the L-shaped rod 103. The detection head 105 is fixedly connected to the bottom of the hydraulic cylinder 104.

[0031] The high-efficiency protective fixing component includes a rectangular box 201, a rectangular rubber ring 202, and rubber particles 203. The top of the support base 101 is fixedly connected to the rectangular box 201, the top of the rectangular box 201 is movably connected to the rectangular rubber ring 202, the top of the rectangular rubber ring 202 is fixedly connected to the rubber particles 203, and the top of the rubber particles 203 is movably connected to the main board body 102.

[0032] The support base 101 ensures the installation of the L-shaped rod 103, the L-shaped rod 103 ensures the installation of the hydraulic cylinder 104, the hydraulic cylinder 104 ensures the up-and-down movement of the detection head 105, the rectangular box 201 ensures the connection of the rectangular rubber ring 202, and the rectangular rubber ring 202 ensures the installation of the rubber granules 203. The detection head 105 is an ICT test probe.

[0033] Rectangular rubber rings 202 are equidistantly distributed on rectangular box 201;

[0034] The positional distribution of the aforementioned components ensures uniform suction force across all areas of the mainboard body 102.

[0035] The rubber granules 203 are generally arranged with a narrow top and a wide bottom, and V-shaped gaps are formed between the rubber granules 203.

[0036] The V-shaped gaps between the rubber particles 203 provide a guarantee for adapting to the protrusions and welding height differences on the main board body 102.

[0037] The high-efficiency protective fixing component also includes a rectangular ventilation slot 204, which is formed through the top of the rectangular box 201;

[0038] The rectangular ventilation slot 204 provides a guarantee for the rectangular box 201 to connect with the rectangular rubber ring 202.

[0039] The high-efficiency protective fixing component also includes a receiving pipe 205 and an inhaler 206. The front end of the rectangular box 201 is fixedly inserted into one end of the receiving pipe 205, and the other end of the receiving pipe 205 is fixedly connected to the inhaler 206.

[0040] The receiving pipe 205 is used to connect the inhaler 206 and the rectangular box 201. The model of the inhaler 206 is DVP-302.

[0041] Working principle: The main board body 102 is placed on the rubber particles 203 on top of the rectangular rubber ring 202. At the same time, a small force is applied downward to press the main board body 102, so that the protruding area and height difference above it are locked into the gap between the rubber particles 203. Then, the suction machine 206 is turned on. With the cooperation of the receiving pipe 205, a negative pressure is generated in the rectangular box 201. The negative pressure is then transmitted through the rectangular ventilation groove 204 to the rectangular rubber ring 202 and the rubber particles 203, which firmly adsorb the main board body 102. Then, the hydraulic cylinder 104 is turned on, which drives the detection head 105 to move down to contact the main board body 102 and perform detection on the main board body 102.

[0042] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:
