Description

Technical Field

[0001] The utility model belongs to the technical field of memory bar testing equipment, and in particular relates to a board disassembling device used for disassembling a PCB of a memory testing machine. Background Art

[0002] In the industry, the test module in the memory chip tester is usually composed of multiple test modules to realize the communication test function. Each test module includes two parallel PCBs, which are connected by a connector.

[0003] In memory chip testers, in order to reduce the size of the entire machine, the gaps between test modules are often small, making it difficult to find a point of force to remove the board on the machine. When maintenance work needs to be done on a memory chip tester, the PCB in the test module generally needs to be replaced. The general practice in the industry is to completely remove the entire test module from the tester, then gradually disassemble the related components, and finally manually separate the two PCBs. This practice not only affects the efficiency of maintenance work, but also brings the risk of PCB damage if tools are used to forcibly pry the PCB through the gap.

[0004] Therefore, it is necessary to design a PCB disassembly device that can facilitate PCB disassembly and reduce the risk of PCB damage. Utility Model Content

[0024] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, this embodiment designs a board disassembly device for disassembling a PCB of a memory tester, including components such as a board disassembly member 4 and a rotating pin 5.

[0027] The memory tester includes a plurality of test modules distributed in a rectangular array; Figure 3 FIG. 4 shows six test modules distributed in 2*3 arrangement, but in actual situations, the memory tester may have more or fewer test modules.

[0028] Each test module includes an upper PCB board 1, a lower PCB board 3, an isolation frame 2 and other components; wherein the upper PCB board 1 and the lower PCB board 3 are parallel to each other, and the upper PCB board 1 is located above the lower PCB board 3, and the upper PCB board 1 and the lower PCB board 3 are separated by the isolation frame 2. The lower PCB board 3 and the lower PCB board 3 are electrically connected through a connector, thereby ensuring communication between the upper PCB board 1 and the lower PCB board 3.

[0029] The isolation frame 2 can be a square frame structure or a frame structure of other shapes, depending on the shapes of the upper PCB board 1 and the lower PCB board 3. A fan-shaped groove 21 is provided on the side wall of the isolation frame 2. The fan-shaped groove 21 can be provided on the outer wall of the isolation frame 2 or on the inner wall of the isolation frame 2.

[0030] The two opposite sides of the isolation frame 2 are respectively provided with fan-shaped grooves 21 , and the panel removal members 4 are respectively provided in the fan-shaped grooves 21 .

[0031] The panel removing member 4 of the panel removing device is rotatably connected to the fan-shaped groove 21 through a rotating pin 5, and a panel removing member 4 is correspondingly arranged in each fan-shaped groove 21, and the panel removing member 4 is in a bent strip shape, and the oblique lower end of the panel removing member 4 is a pressing handle 41, and the oblique upper end of the panel removing member 4 is a pushing portion 42, and the pushing portion 42 is an outward convex structure, and the upper end of the outward convex structure; when the panel removing member 4 rotates forward, the pushing portion 42 can vertically extend out of the upper edge of the isolation frame 2, thereby pushing the upper PCB board 1 upward; when the panel removing member 4 rotates reversely, the pushing portion 42 can vertically shrink to below the upper edge of the isolation frame 2, thereby avoiding the upper PCB board 1 from fitting with the upper surface of the isolation frame 2.

[0032] The rotating pin 5 is provided with a torsion spring for resetting the panel removal member 4. The elastic force of the torsion spring is used to drive the oblique lower end of the panel removal member 4 to rotate upward. In the absence of external force, the elastic force of the torsion spring can enable the push portion 42 to shrink vertically to below the upper edge of the isolation frame 2.

[0033] A side groove 11 is provided on the edge of the upper PCB board 1, and the side groove 11 is located just above the pressing handle 41. When the ejector tool 6 passes through the side groove 11 and presses down the panel removal component 4, the pressing handle 41 at the oblique lower end of the panel removal component 4 is subjected to the downward pressure of the ejector tool 6, so that the panel removal component 4 rotates around the rotating pin 5 as the axis, so that the pushing portion 42 at the oblique upper end of the panel removal component 4 can push the upper PCB board 1 upwards, so as to facilitate the removal of the upper PCB board 1.

[0034] In a memory chip tester, the board disassembly device can improve the convenience of disassembling a single PCB, improve maintenance efficiency, and reduce the risk of damaging the PCB. In addition, the structure of this embodiment has the advantage of a delicate structure, does not affect the compact arrangement of the test module of the normal tester; and can realize the disassembly of a single PCB without disassembling the entire disassembly module, thereby improving maintenance efficiency.

[0035] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
