Technical Field
[0001] The utility model relates to the technical field of electronic product test benches, in particular to an electronic product test bench. Background Art
[0002] Electronic products are related products that use electricity as the basis of their work, mainly including: watches, smart phones, telephones, televisions, DVD players, VCRs, camcorders, radios, tape recorders, combination speakers, laser turntables (CDs), computers, game consoles, mobile communication products, etc. Since early products mainly used vacuum tubes as basic components, they are called electronic products.
[0003] After electronic products are produced, they need to be tested for physical properties and electrical properties. Physical properties tests include vibration, drop, and collision tests. Vibration tests require the use of a vibration test bench as the main test equipment. The vibration test bench includes a vibration bench and a control box. The control box controls the vibration direction and frequency of the vibration bench.
[0004] During vibration testing, electronic products are usually fixed on the surface of a vibration table by means of a clamp, and then the vibration table is powered on to generate vibration to achieve the test effect. Drop testing is generally performed by lifting the device to a certain height and then dropping it naturally, and then observing the degree of damage to the electronic product after the drop. The collision test also requires related equipment for testing. The above three tests require different equipment for testing, and the equipment purchase cost is relatively high. Therefore, an electronic product test bench is proposed to solve the above problems. Utility Model Content

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.
[0030] Embodiment 1
[0031] See also Figure 1 , an electronic product test bench, comprising:
[0032] Vibration table 1; and
[0033] A threaded blind hole 2, which is arranged on the upper surface of the vibration table 1;
[0034] Based on the above, the vibration table 1 is an existing device, and its specific principle and structure are not described here. The setting of the threaded blind hole 2 retains the function of the vibration table 1 for fixing the clamp, and enables the fixing part 3, the fixing frame 5 and other structures to be interconnected with the vibration table 1.
[0035] like Figure 1-Figure 3 As shown, the fixing member 3 is set on the top of the vibration table 1 by screws, and includes a fixing block 31, a guide hole 33 and a positioning screw 34. The fixing member 3 includes a fixing block 31, and the upper surface of the fixing block 31 is provided with a fixing hole 32 and a guide hole 33. The outer surface of the fixing block 31 is provided with a threaded side hole, and the threaded side hole is connected to the guide hole 33. The inside of the guide hole 33 is provided with a positioning screw 34, and the positioning screw 34 extends to the inside of the guide hole 33;
[0036] A lifting column 4 is disposed inside the guide hole 33. The lifting column 4 includes a hollow column 41. The hollow column 41 is disposed inside the guide hole 33. A scale is disposed on the outer surface of the hollow column 41. A transverse plate 42 is disposed on the top of the hollow column 41.
[0037] Based on the above, the fixing member 3 cooperates with the lifting column 4 so that the lifting column 4 can move vertically along the direction of the guide hole 33, thereby changing the height of the lifting column 4. By referring to the height of the lifting column 4, the electronic product can be dropped from a constant height for testing.
[0038] like Figure 1 , Figure 4-Figure 6 As shown, a fixing frame 5 is set on the top of the vibration table 1 by screws, and the fixing frame 5 includes a fixing base 51, and the fixing base 51 is set on the top of the vibration table 1 by screws, and a fixing vertical plate 52 is set at one end of the fixing base 51;
[0039] The connecting rod 6 and the force block 7 are both arranged between the fixing frames 5 through nuts. The connecting rod 6 includes a main rod body 61, which is arranged between the fixing vertical plates 52. Threaded rods 62 are arranged at both ends of the main rod body 61. The threaded rods 62 are connected to the fixing vertical plates 52 through nuts. The force block 7 includes a triangular block 71. The outer surface of the triangular block 71 is provided with a mounting hole 72. The triangular block 71 is sleeved on the outside of the main rod body 61.
[0040] Based on the above, the fixing frame 5 plays a supporting role, so that the connecting rod 6 and the force block 7 are connected and fixed to the fixing frame 5 under the action of the screws. At this time, the force block 7 is mainly subjected to the clamping force of the fixing frame 5, and the clamping force comes from the cooperation between the nut and the connecting rod 6. Therefore, when the nut is loosened, the angle of the force block 7 can also be adjusted. By adjusting the angle of the force block 7, more protrusions and depressions appear on the upper surface of the vibration table 1. When the electronic product is placed on the vibration table 1 for vibrating, the electronic product will collide with the force block 7, and the effect of the collision test is achieved.
[0041] Embodiment 2
[0042] On the basis of the first embodiment, by disassembling the fixing frame 5, the force bearing block 7 is vertically fixed on the upper surface of the vibration table 1 by the action of the long screws, that is, Figure 7 In the state, the electronic product is placed on the upper surface of the vibration table 1, and the power is turned on. Under the action of vibration, the electronic product collides with the force block 7, that is, a collision test of the electronic product at another angle is realized.
[0043] In actual use, the fixing frame 5, the connecting rod 6 and the force block 7 can be installed according to actual needs. When not installed, the vibration table 1 can perform vibration detection on the electronic product, that is, detect whether the quality of the electronic product is good enough under vibration.
[0044] When a drop test is required, the fixing member 3 and the lifting column 4 can be installed to control the height of the electronic product falling. By cooperating with the fixing frame 5, the connecting rod 6 and the force block 7, the electronic product can collide with the force block 7 when falling. By changing the inclination angle of the force block 7, the state of the electronic product being hit when falling is made more complex and more in line with the actual situation.
[0045] If a collision test is required, there are two options: Figure 1 In the state, by changing the inclination angle of the force-bearing block 7, the lower surface of the electronic product is more subjected to collision. Figure 7 In the state, after the force-bearing blocks 7 are fixed vertically, the number, position and tilt angle of the force-bearing blocks 7 are changed, and then a collision test is performed on the side of the electronic product;
[0046] The test bench is improved on the basis of the existing vibration table, so that the vibration table 1 can be used to test vibration, drop and collision, achieving the effect of one machine with multiple uses, and different test effects can be obtained by adjusting the force block 7, so as to achieve the effect of reducing the test cost.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
