[0031] This utility model provides an EOL testing device, such as... Figure 1 and Figure 2 As shown, the test body 2 includes a fixture plate 208. During testing, the product to be tested is installed on the fixture plate 208. The test body 2 also includes a detection unit 209, which is located above the fixture plate 208. The detection unit 209 measures the position of the product to be tested, ensuring that the product to be tested is accurately positioned for testing. This facilitates the connection between the interface of the product to be tested and the interface on the test body 2, improving the accuracy of the test results. Furthermore, multiple test bodies 2 are installed on the test cabinet 1, enabling simultaneous testing at multiple workstations.

[0032] Example 1

[0033] like Figure 3 As shown, the fixture plate 208 has a groove 216 for accommodating the product to be tested. That is, before testing, the product to be tested is placed into the groove 216. Further, as... Figure 1 As shown, the fixture plate 208 is also equipped with a plurality of limiting parts 214. The limiting parts 214 are located on one side of the groove 216 and are used to fix the product to be tested in the groove 216. Preferably, the limiting part 214 is a quick clamp, one end of which is installed on the fixture plate 208, and the other end applies a force from top to bottom to the product to be tested, thus restricting the product to be tested in the groove 216. Furthermore, as shown in the figure, Figure 4 As shown, multiple flexible rods 228 are movably installed on the inner wall of the groove 216. The flexible rods 228 contact the outer wall of the product under test and are used for centering the product under test and the groove 216, further ensuring that the product under test is accurately installed in the groove 216.

[0034] Specifically, an adjustment groove 225 is provided on the inner wall of the groove 216. Preferably, at least two adjustment grooves 225 are provided on the inner side of the groove 216, and the two adjustment grooves 225 are located on two symmetrical inner wall surfaces. A movable shaft 227 is rotatably connected inside the adjustment groove 225. One end of the elastic rod 228 is installed on the movable shaft 227, and the other end extends into the groove 216. The contact end between the elastic rod 228 and the product to be tested is spherical. That is, when the product to be tested is placed in the groove 216, the product to be tested contacts the elastic rod 228, causing the elastic rod 228 to bend downward. At this time, the other end of the elastic rod 228 drives the movable shaft 227 to rotate so that the elastic rod 228 can swing. When the product to be tested is completely placed in the groove 216, the spherical end face of the elastic rod 228 contacts the surface of the product to be tested.

[0035] Furthermore, to ensure the stability of the swing of the flexible rod 228 and prevent its deformation from hindering the installation of the product under test, a spring groove 226 is reserved on the inner wall of the groove 216. The spring groove 226 is located at both ends of the adjusting groove 225. A spring is fixedly installed in the spring groove 225, and an adjusting plate 229 is fixedly installed on the other end of the spring. The adjusting plate 229 is sleeved on the flexible rod 228. Specifically, when the flexible rod 228 swings, the adjusting plate 229 moves downward, and the spring connects the adjusting plate 229 and the groove 216, ensuring a reliable connection of the adjusting plate 229 and accurately limiting the position of the flexible rod 228.

[0036] Example 2

[0037] Based on the above-described embodiment one, in order to perform multifunctional testing on the product under test, such as... Figure 3 and Figure 5As shown, the test body 2 also includes a probe 220, which is located below the product under test. The probe 220 contacts the bottom of the product under test. Specifically, a base plate 207 is installed at the bottom of the fixture plate 208, and a cylinder seat 221 is installed at the bottom of the base plate 207. A probe cylinder 222 is installed on the cylinder seat 221, and a probe 220 is installed on the probe cylinder 222. A probe hole 215 is provided on the groove 216. The probe 220 passes through the probe hole 215 and contacts the product under test in the groove 216. After the product under test is installed, the probe 220 is pushed upward by the probe cylinder 222 to pass through the probe hole 215 and contact the product under test, so as to test the product under test.

[0038] like Figure 3 and Figure 6 As shown, L-shaped support base 224, support base one 217 and support base two 218 are bolted to the base plate 207. One end of the fixture plate 208 is snapped into position with the L-shaped support base 224. The L-shaped support base 224, support base one 217 and support base two 218 form an area to support a part of the product to be tested, which is suitable for installing irregular products to be tested.

[0039] A probe cylinder 219 is mounted on the base plate 207. The probe cylinder 219 is located on one side of the L-shaped support 224. A probe 223 is mounted on the probe cylinder 219. The L-shaped support 224 has holes to facilitate the probe 223 to pass through the holes and contact the product to be tested. Specifically, the probe cylinder 219 enables the probe 223 to pass through the holes and contact the product to be tested, thereby performing the test on the product.

[0040] In addition, such as Figure 2 As shown, a rear cylinder 212 is installed on the base plate 207. The rear cylinder 212 is located behind the fixture plate 208. A detection unit 213 is installed at the front end of the rear cylinder 212. The detection unit 213 is located behind the product under test. In actual use, the detection unit 213 is used to turn on the start switch of the product under test, so as to simulate the real working state of the product under test and thus test the product under test.

[0041] The fixture plate 208 is bolted to the base plate 207. Side plates 204 are installed on both sides of the base plate 207. A fixing plate 210 is installed at the front end of the side plate 204. A top cylinder 211 is installed on the fixing plate 210. A detection part 209 is installed at the bottom of the top cylinder 211. The detection part 209 is located above the product to be tested. Its purpose is to accurately confine the product to be tested within the groove 216.

[0042] Example 3

The bottom side of the base plate 207 is connected to the base 201 via a hinge, which facilitates the maintenance of the wiring inside the base 201 and the installation or disassembly of the test body 2. In addition, handles 205 are installed in the middle of both sides of the base 201 to facilitate the removal of the entire test body 2 from the test cabinet 1, making the test body 2 and the test cabinet 1 independent of each other. Multiple control units 202 are provided on the base 201 to control the start and stop of the test body 2. Protective plates 203 are also installed on the three sides of the top of the base plate 207 to protect the product under test.

[0044] Furthermore, since the base plate 207 and the base 201 are hinged, locking parts 206 are installed on both sides of the base 201. The locking parts 206 are located in front of the handle 205. One end of the locking parts 206 is fixedly installed on the base plate 207 to ensure the stability of the connection between the base plate 207 and the base 201. When it is necessary to inspect or repair the test body 2, the locking parts 206 can be opened directly. The locking parts 206 are existing technology and will not be described in detail here.

[0045] like Figure 1 and Figure 8 As shown, the test cabinet 1 has a hinged door 102 at the front end and casters 101 at the bottom. An electrical distribution unit 106 is installed inside.
