Description

Technical Field

[0001] This utility model relates to the field of communication device testing technology, and more specifically to a test fixture for communication devices. Background Technology

[0002] Communication equipment refers to devices used for transmitting and receiving information, enabling communication between people, between people and things, and between things. There are many types of communication equipment, covering a wide range of application areas, including traditional wired and wireless communication technologies. During the production of communication device circuit boards, quality testing is required.

[0003] Existing methods for testing circuit boards typically involve placing the circuit board inside a positioning mold, clamping it with a fixture, and then connecting an external test head to the test pins on the circuit board surface to complete the testing. This testing process reduces the efficiency of circuit board testing because it requires additional clamping and positioning of the circuit board.

[0004] In view of this, the present invention proposes a test fixture for communication devices used in circuit board testing to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a test fixture for communication devices to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a test fixture for a communication device, including a base, a translation plate and a top frame respectively provided on the upper surface of the base, a positioning template provided on the upper surface of the translation plate, a positioning groove opened on the upper surface of the positioning template, a circuit board placed inside the positioning groove, and a clamping test component provided on the surface of the top frame corresponding to the circuit board.

[0007] The clamping test assembly includes a hydraulic rod embedded in the surface of the top frame. A lifting plate is fixedly installed at the telescopic end of the hydraulic rod. A detection plate is provided on the lower surface of the lifting plate. A limit slide rod is slidably connected to the surface of the lifting plate. A clamping frame is fixedly installed at the bottom end of the limit slide rod. A support spring is sleeved on the surface of the limit slide rod. The top and bottom ends of the support spring abut against the lower surface of the lifting plate and the upper surface of the clamping frame, respectively.

[0008] Furthermore, a balance slide bar is fixedly installed on the top of the lifting plate, and the balance slide bar is slidably connected to the top frame; by setting the balance slide bar, the stability of the lifting plate during lifting can be improved, and the lifting plate can be prevented from shaking during movement.

[0009] Furthermore, the clamping frame is positioned corresponding to the edge of the circuit board, and a window is reserved at the center of the clamping frame for the detection board to pass through.

[0010] Furthermore, the circuit board surface is provided with test pins, and the bottom of the detection board is provided with a test head, the position of which corresponds to the test pins, and the test head is electrically connected to the external circuit board detection host.

[0011] Furthermore, the positioning template and the translation plate are detachably installed together by bolts, and the detection plate and the lifting plate are detachably installed together by bolts; depending on the model of the circuit board to be tested, the positioning template and the detection plate can be replaced accordingly, thereby improving the adaptability of the overall device.

[0012] Furthermore, the translation plate and the base are movably connected, and there are two translation plates. A switching assembly is provided between the base and the two translation plates. The switching assembly includes two side plates symmetrically fixedly installed on the left and right sides of the upper surface of the base. A transverse lead screw is rotatably connected between the two side plates. The translation plate is threadedly connected to the surface of the transverse lead screw. A servo motor that drives the transverse lead screw to reciprocate in both directions is fixedly installed on the surface of the right side plate. By setting up the switching assembly, the servo motor drives the transverse lead screw to rotate, which can drive the two translation plates to move and switch the position of the positioning template located on the surface of the translation plate. This allows the circuit board to be picked up and placed inside the other positioning template while the circuit board inside one positioning template is being inspected, thereby further improving the efficiency of circuit board inspection for communication devices.

[0013] Furthermore, two slide rails are fixedly installed on the surface of the base between the two side plates. The two slide rails are symmetrically distributed on the front and rear sides of the transverse lead screw, and the translation plate is slidably connected to the slide rails. By setting the slide rails, the stability of the translation plate when moving can be improved, and the translation plate can be prevented from shaking during the movement.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, when testing the circuit board of a communication device, the circuit board is fitted into the positioning groove on the surface of the positioning template. The hydraulic rod is extended to drive the lifting plate to move downward. The detection plate moves downward synchronously so that the test head contacts the test pin. The external circuit board testing host completes the testing action. During the testing process, the lifting plate moves downward and drives the clamping frame to move downward synchronously. The clamping frame abuts against the edge of the circuit board, and the support spring is compressed. At the beginning of the testing action, the elastic force of the support spring drives the clamping frame to clamp and fix the circuit board, eliminating the need for additional clamping operations and thus improving the efficiency of circuit board testing.

[0016] 2. This utility model, by setting a balance slide bar, can improve the stability of the lifting plate during lifting and lowering, and prevent the lifting plate from shaking; by setting a switching component, using a servo motor to drive the horizontal lead screw to rotate, it can drive two translation plates to move, and switch the position of the positioning template located on the surface of the translation plates. Thus, while the circuit board inside one positioning template is being inspected, the circuit board can be picked up and placed inside the other positioning template, thereby further improving the efficiency of circuit board inspection of communication devices; by setting a slide rail, the stability of the translation plate during movement can be improved.

[0032] When testing the communication device circuit board 5, the circuit board 5 is fitted into the positioning groove on the surface of the positioning template 4. The hydraulic rod 6 is extended to drive the lifting plate 7 to move down. The detection plate 8 moves down synchronously so that the test head 14 contacts the test pin 13.

This allows the circuit board 5 to be picked up and placed inside the other positioning template 4 while the circuit board 5 inside one positioning template 4 is being inspected, thereby further improving the efficiency of circuit board 5 inspection for communication devices.
