[0014] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0015] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0017] like Figures 1 to 3As shown, a multi-station test tool for a radio frequency module comprises a housing 1, a plurality of first screw rod assemblies 3 are installed side by side on a workbench 2 of the housing 1, the output ends of the first screw rod assemblies 3 are connected one-to-one with a plurality of slides 4, driving the slides 4 to perform reciprocating linear motion, a carrier 5, a second driving member 6, a lifting cylinder 7 and a probe test board 8 are provided on the slide 4, the output end of the second driving member 6 is connected with the carrier 5, driving the carrier 5 and the slide 4 to move in the same direction, the output end of the lifting cylinder 7 is connected with the probe test board 8, driving the probe test board 8 to rise and fall, a plurality of spring probes 81 are integrated on the probe test board 8, a fixed plate 11 is provided in the housing 1, a plurality of third cylinders 9 are installed on the fixed plate 11, the output end of the third cylinder 9 is connected with a pressing plate 91, driving the pressing plate 91 to vertically approach or move away from the probe test board 8. Specifically, in this embodiment, the casing 1 is formed by welding sheet metal plates, and a plurality of first screw assemblies 3 are placed on the workbench 2 along the width direction of the casing 1. The first screw assemblies 3 are used to drive the slide 4 to move, thereby driving the carrier 5, the second drive member 6, the lifting cylinder 7 and the probe test board 8 on the slide 4 to move as a whole outside the casing 1, so as to facilitate the operator or the manipulator to disassemble and assemble the RF module to be tested. During use, the operator places the RF module on the carrier 5, and then the second drive member 6 drives the carrier 5 to move to just below the probe test board 8. At this time, the first screw assembly 3 drives the slide 4 to reset, moves into the housing 1, and handles the bottom of the pressure plate 91. At this time, the lifting cylinder 7 drives the probe test board 8 to press down, acting on the RF module to be tested on the carrier 5, so that the probe 81 contacts it. Because the probe 81 passes through the probe test board 8 and has a certain elasticity, the electrical connection with the RF module to be tested is unstable at this time. In order to ensure the electrical connection, the pressure plate 91 is driven down by the third cylinder 9 to ensure that the probe 81 on the probe test board 8 is in stable contact with the RF module to be tested. The entire tooling can test multiple RF modules simultaneously, and the testing process is fully automated without manual labor, which greatly saves labor costs and improves testing efficiency.

[0018] like Figure 2 As shown, an electromagnetic shielding cover 92 is provided on one side of the pressing plate 91 facing the probe test board 8. Specifically, the electromagnetic shielding cover 92 can isolate two adjacent probe test boards 8 to prevent mutual interference during testing and improve test accuracy.

[0019] like Figure 2 As shown, the lower end surface of the pressing plate 91 is also provided with a contact plate 911, and the contact plate 911 is connected to the pressing plate 91 through a spring column. Specifically, the contact plate 911 with a certain buffering capacity is used to contact the probe test board 8, which can play a buffering role and avoid hard pressure contact, which is easy to damage the probe test board 8.

[0020] like Figure 2As shown, a guide column 93 is further connected between the pressing plate 91 and the fixing plate 11. Specifically, the guide column 93 plays a guiding role and ensures that the pressing plate 91 remains stable and does not swing during the lifting process, and the pressure acting on the probe test plate 8 is uniform.

[0021] like Figure 2 As shown, the housing 1 is provided with sliding columns 12 at the four corners, and the four sliding columns 12 corresponding to the four corners of the fixing plate 11 are detachably connected. Specifically, in this embodiment, it is convenient to manually adjust the height of the fixing plate 11 to ensure that the third cylinder 9 on the fixing plate 11 can drive the pressing plate 91 to act on the probe test plate 8 to complete the test.

[0022] Specifically, an observation window and an operation screen are provided at the front end of the housing 1, so that the operator can visually operate the first screw assembly 3, the second drive member 6, the lifting cylinder 7 and the third cylinder 9 through the operation screen.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
