Description

Technical Field

[0001] The utility model relates to the technical field of computer shell hardness detection, in particular to a computer shell hardness detection device. Background Art

[0002] The hardness of a computer case is related to the protective effect of the case on important internal components. Before the computer case is assembled, the hardness of the computer case needs to be tested to avoid computer cases with hardness defects that affect the quality of computer products. Existing computer case hardness testing devices generally have problems in the sampling link of the case surface hardness. If there are too many sampling points on the surface, the efficiency of the assembly line case hardness test will be affected. If there are too few sampling points, the randomness of the sampling cannot be guaranteed and the test lacks persuasiveness.

[0003] For example, a new type of notebook shell hardness detection device is disclosed in the Chinese utility model patent with announcement number CN219104609U. Although the scheme uses the detection cylinder to drive the hardness tester to press down to perform hardness detection, the hardness tester can only select sampling points at a fixed position in the middle of the shell for one test. For batch shell hardness detection, hardness sampling detection at a uniform position is not convincing. Based on this, a computer shell hardness detection device is proposed. Utility Model Content

Figure 1 The entire section of the closed-loop slide 3 in the embodiment is a curved trend. At this time, the servo motor 4 needs to adopt an intermittent start-stop movement mode. When the servo motor 4 is paused, the hardness meter mechanism 6 can be pressed down for detection. A lower sliding groove 17 is provided on the lower side of the limit platform 15.

[0023] The left and right driving mechanism of the shell includes a push plate 9 which is slidably connected to the inner side of the limit slider 5. One end of the push plate 9 is movably connected to a movable connecting plate 10. The minimum length of the movable connecting plate 10 should be sufficient to ensure that the movable connecting plate 10 can still movably contact the push plate 9 when the movable connecting plate 10 is maximally offset. One end of the movable connecting plate 10 is rotatably connected to a connecting rod 11. A connecting rod driving mechanism is provided on one side of the connecting rod 11 to enable the connecting rod 11 to reciprocate left and right.
