[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0025] See also Figure 1 , Figure 1 Schematic diagram of a pneumatic test device provided by an exemplary embodiment of the utility model. The utility model discloses a pneumatic test device, comprising: a fixed platform 1 and a test assembly. The fixed platform is used to place a device under test 2; the test assembly is fixedly arranged on two opposite sides of the fixed platform 1, and the test assembly includes a probe module 3 and a cylinder 4, and the cylinder 4 is arranged on two opposite sides of the fixed platform 1. The probe module 3 is provided with a probe for connecting to the terminal of the device under test 2.

[0026] The probe module 3 is connected to the cylinder 4, and the cylinder 4 is used to drive the probe modules 3 on both sides of the fixed platform to switch between a first state and a second state, wherein the first state is that the probe modules on both sides of the fixed platform are in a clamped state, so that the probes on the probe module 3 are connected to the terminal posts of the device under test 2; the second state is that the probe modules on both sides of the fixed platform are in a separated state, so that the probes on the probe module 3 are separated from the terminal posts of the device under test 2.

[0027] Optionally, please refer to the attached Figure 1 The test assembly includes a fixing member 5 for fixing the test assembly on the fixed platform 1, and a cylinder support member 6 for fixing the cylinder 4. The cylinder support member 6 and the fixing member 5 form a certain angle so that the movement of the cylinder 4 is parallel to the surface of the fixed platform.

[0028] Exemplarily, the side of the fixed platform 1 is in a vertical state, and the upper surface is in a horizontal state. The fixing member 5 of the test assembly is directly fixed to the side of the fixed platform 1, and the fixing method can be screws, bolts, welding, etc., which is not specifically limited in this embodiment. The cylinder support member 6 is connected to the fixing member 5 and is parallel to the upper surface of the fixed platform 1. The cylinder is fixed to the upper surface of the cylinder support member 6. In this embodiment, the cylinder support member 6 and the fixing member 5 are at a 90-degree angle.

[0029] Optionally, the test assembly further comprises a cylinder movable part 7 , one side of the cylinder movable part 7 is connected to the probe module 3 , and the other side of the cylinder movable part 7 is connected to the cylinder 4 , and the movement of the cylinder 4 drives the probe module 3 to move.

[0030] Continue to refer to the attached Figure 1 , the cylinder movable part 7 is arranged on the upper surface of the cylinder support part 6, and is located between the cylinder 4 and the device under test 2. One side of the cylinder movable part 7 is connected to the probe module 3, and the other side is connected to the cylinder 4. When the cylinder 4 reciprocates, the cylinder movable part 7 and the probe module 3 on the cylinder movable part are driven to reciprocate. When the cylinder 4 extends, the probe module 3 approaches the device under test 2 until the probe is connected to the terminal of the device under test 2, and the subsequent test operation is performed. When the cylinder 4 retracts, the probe module 3 moves away from the device under test 2 until the probe is disconnected from the terminal of the device under test 2, and the test operation is completed.

[0031] For further information, see Figure 2 A slide rail 8 is provided between the cylinder movable part 7 and the cylinder support part 6 to reduce the friction between the cylinder movable part 7 and the cylinder support part 6.

[0032] Furthermore, the cylinder movable part 7 and the probe module 3 are connected by quick release, and different probe modules 3 are used for different types of tested equipment 2. Its simple structure is more convenient for customers to install and replace, and is more efficient.

[0033] For further information, see Figure 3 , probes of different lengths are arranged on the probe module 3, which are used for the devices under test with different signals. Exemplarily, probes of different lengths are arranged on the probe module. For example, when only six target terminals of the device under test need to be tested, the six pre-arranged longer probes are connected to the six target terminals, and the other probes are relatively short and do not contact the terminals of the device under test 2.

[0034] Optionally, the device under test 2 is arranged on a tooling board, and a slide rail 8 is arranged between the tooling board and the fixed platform. The tooling board transports the device under test to between two probe modules for testing through the slide rail. When the test is completed, the device under test is transported to a designated position, and the probe module waits for the next device under test. This cycle is repeated to achieve fast operation, speed up the detection speed, and greatly improve the detection efficiency.
