Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a pressure resistance testing device for the metal casing of electronic components. Background Technology

[0002] The compressive strength testing device for electronic component metal casings is specifically designed to test the compressive strength of electronic component metal casings. It assesses the casing's ability to withstand pressure and its performance stability in practical use by applying a certain amount of pressure. During the test, the device gradually applies pressure and records the deformation and stress data of the metal casing under pressure until the casing fails or the test is terminated. By analyzing this data, the compressive strength and quality level of the metal casing can be evaluated.

[0003] Existing electronic component metal casing compression testing devices mainly include a base, support, hydraulic rod, pressure plate, testing base, pressure sensor array, and testing platform. In use, the metal casing of the electronic component to be tested is placed on the testing platform, and the hydraulic rod is driven, causing the pressure plate to compress the metal casing. Simultaneously, the metal casing is accurately tested for compression resistance based on real-time data from the pressure sensor array. However, in actual use, the metal casing may slip or even fly off under pressure during compression testing, directly affecting the testing results and potentially injuring nearby personnel. Furthermore, compression testing in a single direction cannot accurately determine the specific compression resistance of the electronic component's metal casing. These limitations in compression testing directly affect the quality of the electronic component's metal casing, potentially leading to problems such as cracking or deformation during subsequent use, thus affecting the normal operation of the electronic component.

[0004] Therefore, a pressure resistance testing device for the metal casing of electronic components is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 6This utility model provides a technical solution: a pressure resistance testing device for the metal casing of electronic components, including a base 1, a bracket 2 fixedly connected to the top of the base 1, a hydraulic rod 3 fixedly installed at the middle of the top of the bracket 2, the output end of the hydraulic rod 3 extending to the bottom of the top of the bracket 2, a pressure plate 4 fixedly connected to the output end of the hydraulic rod 3, a detection base 5 fixedly installed at the middle of the top of the base 1, a pressure sensor array 51 fixedly installed at the top of the detection base 5, a detection platform 52 fixedly connected to the top of the pressure sensor array 51, a positioning structure 6 fixedly installed at the edge of the top of the base 1, and a cleaning structure 7 fixedly installed at the middle of the top of the base 1. The structure 6 includes a slide rail 61 fixedly connected to the top of the base 1. The top of the slide rail 61 is fixedly connected to the bottom of the top of the bracket 2. A slide plate 62 is slidably connected inside the slide rail. A circular block 63 is rotatably connected to the middle of the slide plate 62. An electric telescopic rod 64 is fixedly installed on the side of the circular block 63 near the detection base 5. A rectangular block 65 is fixedly connected to the output end of the electric telescopic rod 64. A suction cup 66 is fixedly connected to the side of the rectangular block 65 away from the electric telescopic rod 64. Driving the electric telescopic rod 64 causes the suction cup 66 to squeeze the metal shell of the electronic component and form a fixing effect, thereby ensuring the stability of the metal shell of the electronic component during the pressure test.

[0027] like Figures 2-4 As shown, an air passage 67 extending through the suction cup 66 is provided inside the rectangular block 65. The top of the air passage 67 extends beyond the top of the rectangular block 65. A rectangular box 69 is fixedly connected to the top of the rectangular block 65. Several ventilation holes are provided at the top of the rectangular box 69. A pull rod 610 is slidably connected to the middle of the top of the rectangular box 69. A rubber ball 68 is fixedly connected to the bottom of the pull rod 610. The outer wall of the bottom of the rubber ball 68 is inserted into the inner wall of the top of the air passage 67. The top of the bottom of the pull rod 610 is fixedly connected to... Spring 611 is fixedly connected to the top of the inner wall of rectangular box 69. Air inside suction cup 66 passes through air passage 67, lifts rubber ball 68, and finally exits through vent. After the air is discharged, rubber ball 68 resets under the reaction force of spring 611, and then re-blocks air passage 67. At this time, when electronic components want to detach from suction cup 66, negative pressure is formed between suction cup 66 and the metal shell of electronic components, which further improves the fixing ability of suction cup 66.

[0028] like Figure 3 As shown, a mounting bracket 612 is fixedly connected to the side of the slide plate 62 away from the electric telescopic rod 64. A servo motor 613 is fixedly installed inside the mounting bracket 612. The output end of the servo motor 613 is fixedly connected to the side of the circular block 63 away from the electric telescopic rod 64, driving the servo motor 613 to rotate, which in turn drives the circular block 63 to rotate, which in turn drives the metal shell of the electronic component to rotate, thereby enabling multi-angle detection of the metal shell of the electronic component and improving the detection effect.

[0029] like Figure 2 As shown, a servo motor 614 is fixedly mounted on the top of the base 1. A transmission assembly 615 is fixedly mounted on the output end of the servo motor 614. The transmission assembly 615 includes two transmission wheels and a toothed belt. The output end of the servo motor 614 is fixedly connected to the side of one of the transmission wheels away from the slide rail 61. The rear end of the transmission wheel extends into the interior of the slide rail 61. A bidirectional lead screw 616 is fixedly connected to the rear end of the transmission wheel. A slider 617 is symmetrically threaded onto the outer wall of the bidirectional lead screw 616. A connecting rod 618 is rotatably connected to the top of each of the two sliders 617. The tops of the two connecting rods 618 are symmetrically rotatably connected to the bottom of the slide plate 62. The servo motor 614 is driven, which in turn drives the bidirectional lead screw 616 to rotate, which in turn drives the connecting rod 618 to rotate. Thus, the height of the suction cup 66 can be adjusted according to the size of the metal shell.

[0030] like Figure 5 As shown, the cleaning structure 7 includes a collection frame 71 that is movably fitted onto the outer wall of the detection base 5. Slide rails 72 are fixedly connected to opposite sides of the outer surface of the collection frame 71. Sliding blocks 73 are slidably connected to the inner walls of the two slide rails 72. Sleeve rods 74 are rotatably connected to the side of the two sliding blocks 73 that is far apart from each other. Round rods 75 are slidably connected to the inside of the two sleeve rods 74. Brushes 76 are fixedly connected to the side of the two round rods 75 that is far away from the slide rails 72. The sliding brushes 76 can sweep debris and other debris from the surface of the detection platform 52 into the collection frame 71. The collection frame 71 can be slid out from the outer wall of the detection base 5 to process the debris stored inside.

[0031] like Figure 6 As shown, springs 78 are fixedly connected to the inner walls of the two sleeve rods 74 on the side away from the slide rail 72. The ends of the two springs 78 near the slide rail 72 are respectively fixedly connected to the ends of the two round rods 75 near the slide rail 72. The springs 78 can cause the bottom end of the brush 76 to be in close contact with the top of the detection platform 52, thereby ensuring the cleaning effect.

[0032] like Figure 5 As shown, two baffles 77 are symmetrically fixedly connected at the top of the base 1 near the round rod 75. The side of the two baffles 77 away from the detection base 5 overlaps with the side of the brush 76 near the detection base 5. The baffles 77, together with the spring 78, can restrict the position of the brush 76, thereby allowing the brush 76 to be properly stored.

[0033] The working principle of this invention is as follows: In use, the metal casing of the electronic component is placed on the surface of the detection base 5. The servo motor 614 is driven, which in turn drives the bidirectional lead screw 616 to rotate, which in turn drives the connecting rod 618 to rotate. The height of the suction cup 66 is adjusted according to the size of the metal casing. When the suction cup 66 is in the appropriate position, the electric telescopic rod 64 is driven, causing the suction cup 66 to press against the metal casing of the electronic component, thus achieving a fixing effect. During this process, air inside the suction cup 66 passes through the air passage 67, lifting the rubber ball 68, and finally exiting through the vent. After the air is expelled, the rubber ball 68 resets under the reaction force of the spring 611, thus re-blocking the air passage 67. At this point, when the electronic component wants to detach from the suction cup 66, a negative pressure is formed between the suction cup 66 and the metal casing of the electronic component, further enhancing the fixing ability of the suction cup 66. After a pressure test is completed, the servo motor 613 is driven to rotate, which in turn drives the circular block 63 to rotate, which in turn drives the metal casing of the electronic component to rotate. During this process, the height of the sliding plate 62 is adjusted in a timely manner according to the size and shape of the metal casing, so that the metal casing is always connected to the test base 5 during the comprehensive pressure test from multiple angles, thus ensuring the accuracy of the test. Before the pressure test begins, the brush 76 is pulled up and rotated, causing the brush 76 to detach from the baffle 77, while keeping the brush 76 overlapping with the top of the test platform 52. At this time, the brush 76 is slid to clean the debris on the surface of the test platform 52 into the collection frame 71. Afterwards, the reverse steps are used to fix the brush 76 back to one side of the baffle 77, and then the collection frame 71 is slid out from the outer wall of the test base 5 to process the debris stored inside.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
