Description

Technical Field

[0001] This utility model relates to the field of FCT testing fixtures, and in particular to a rapid pressing structure for a lever-type FCT testing fixture. Background Technology

[0002] The FCT test fixture is the core hardware carrier of the FCT test system and a key bridge connecting the "product under test" and the "test system". It achieves product positioning, signal connection and auxiliary operation through precise mechanical structure, ensuring that FCT test can verify product functions efficiently and stably. It is the "infrastructure" for realizing batch functional testing in electronic manufacturing.

[0003] When the test head is pressed down, a single guide post or no dedicated guide component is often used. During the pressing process, the pressure head is prone to deviation, which leads to misalignment between the test probe and the test point on the workpiece, affecting the accuracy of the test results. The pressing speed of the test head is slow, resulting in poor testing efficiency. When the pressure head contacts the workpiece, it is a rigid collision, which can easily damage precision workpieces (such as flexible circuit boards and microchips) and increase the defect rate. To address this, we propose a rapid pressing structure for a lever-type FCT test fixture. Utility Model Content

[0004] The main objective of this invention is to provide a rapid pressing structure for a lever-type FCT testing fixture, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapid pressing structure for a lever-type FCT test fixture includes a support frame, a pressing component is embedded in the front surface of the support frame, a pressing head structure is fixedly installed on the lower surface of the pressing component, and a test platform is fixedly installed below the pressing head structure on the support frame.

[0007] Furthermore, the support frame includes a support frame, a movable groove, and a base. The support frame is fixedly installed on the upper surface of the base at the rear, and the movable groove is opened on the front surface of the support frame at the top.

[0008] Furthermore, the pressing assembly includes a U-shaped plate, an L-shaped rod, a cylinder, a rotating shaft, a movable hole, and a piston rod. The piston rod is fixedly connected to the output end of the cylinder. The U-shaped plate is fixedly installed on the upper surface of the piston rod. The rotating shaft is fixedly connected to the U-shaped plate. A movable hole is opened on one side surface of the L-shaped rod at the top. The rotating shaft is embedded in the movable hole.

[0009] Furthermore, the cylinder is embedded inside the support frame, the L-shaped rod is embedded inside the movable groove, and the test platform is fixedly installed on the upper surface of the base.

[0010] Furthermore, the pressure head structure includes a pressure plate, a buffer pad, a telescopic rod, a spring, a U-shaped frame, and a test head. The buffer pad is fixedly installed on the lower surface of the pressure plate at the middle position, and the telescopic rod is fixedly installed on the lower surface of the pressure plate at the edge position. There are four sets of telescopic rods, and springs are sleeved on the surface of each telescopic rod.

[0011] Furthermore, the pressure plate is fixedly installed on the lower surface of the L-shaped rod, and the test head is located above the test platform.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-5 A lever-type FCT test fixture has a rapid pressing structure, including a support frame 1, a pressing component 2 is embedded on the front surface of the support frame 1, a pressing head structure 3 is fixedly installed on the lower surface of the pressing component 2, and a test table 4 is fixedly installed below the pressing head structure 3 on the support frame 1.

[0023] Specifically, the support frame 1 supports the pressing component 2 and the test table 4. The pressing component 2 drives the pressing head structure 3 to press down, and the test table 4 places and fixes the workpiece. The entire pressing structure is powered by a battery and controlled by external equipment.

[0024] In a preferred embodiment, the support frame 1 includes a support frame 101, a movable groove 102, and a base 103. The support frame 101 is fixedly installed on the upper surface of the base 103 at the rear, and the movable groove 102 is opened on the front surface of the support frame 101 at the top.

[0025] Specifically, the base 103 supports the support frame 101, and the battery can be installed inside the base 103. The inside of the support frame 101 is hollow, which facilitates the normal operation of the pressure component 2.

[0026] In a preferred embodiment, the pressing component 2 includes a U-shaped plate 201, an L-shaped rod 202, a cylinder 203, a rotating shaft 204, a movable hole 205, and a piston rod 206. The output end of the cylinder 203 is fixedly connected to the piston rod 206. The U-shaped plate 201 is fixedly installed on the upper surface of the piston rod 206. The rotating shaft 204 is fixedly connected to the U-shaped plate 201. A movable hole 205 is opened on one side surface of the L-shaped rod 202 at the top. The rotating shaft 204 is embedded in the movable hole 205.

[0027] Specifically, by driving the cylinder 203, the piston rod 206 is moved up and down. Since the rotating shaft 204 is embedded inside the movable hole 205, when the U-shaped plate 201 moves up and down, the position between the rotating shaft 204 and the movable hole 205 can be changed, thereby changing the angle of the L-shaped rod 202. When the U-shaped plate 201 moves down, the end of the L-shaped rod 202 near the U-shaped plate 201 moves down and the other end tilts up, and vice versa. The rear surface of the L-shaped rod 202 is arc-shaped, so the rotation of the L-shaped rod 202 is not affected by the U-shaped plate 201.

[0028] In a preferred embodiment, the cylinder 203 is embedded in the support frame 101, the L-shaped rod 202 is embedded in the movable groove 102, and the test platform 4 is fixedly installed on the upper surface of the base 103.

[0029] Specifically, by installing the cylinder 203 inside the support frame 101, the cylinder 203 is not affected by the outside when it moves. When the piston rod 206 moves up and down, the L-shaped rod 202 rotates inside the movable groove 102. The internal space of the movable groove 102 is larger than the L-shaped rod 202, so the L-shaped rod 202 can move inside the movable groove 102. The test platform 4 is installed on the upper surface of the base 103 for placing the workpiece.

[0030] In a preferred embodiment, the pressure head structure 3 includes a pressure plate 301, a buffer pad 302, a telescopic rod 303, a spring 304, a U-shaped frame 305, and a test head 306. The buffer pad 302 is fixedly installed on the lower surface of the pressure plate 301 at the middle position, and the telescopic rod 303 is fixedly installed on the lower surface of the pressure plate 301 at the edge position. There are four sets of telescopic rods 303. The surface of each telescopic rod 303 is fitted with a spring 304. The lower surface of the telescopic rod 303 is fixedly connected to the U-shaped frame 305, and the inner surface of the U-shaped frame 305 is embedded with the test head 306.

[0031] Specifically, the pressure plate 301 drives the buffer pad 302 to move up and down. The buffer pad 302 is made of rubber and has a certain buffering effect. When the pressure plate 301 is pressed down, the spring force of the spring 304 is released, so the test head 306 can be pressed down by the U-shaped frame 305. When the test head 306 contacts the workpiece, it cannot move down. The buffer pad 302 squeezes the test head 306 again, so that the test head 306 is pressed down stably and plays a certain buffering role to prevent the test head 306 from directly colliding with the workpiece.

[0032] In a preferred embodiment, the pressure plate 301 is fixedly installed on the lower surface of the L-shaped rod 202, and the test head 306 is located above the test platform 4;

[0033] Specifically, by fixing the pressure plate 301 below the L-shaped rod 202, when the L-shaped rod 202 rotates, the pressure plate 301 rotates together with the L-shaped rod 202 and will generate a certain rotation angle. When the test head 306 presses down, it can test the workpiece located above the test platform 4.

[0034] It should be noted that during use, the workpiece to be tested is placed on the test platform 4, and the cylinder 203 is activated, causing the piston rod 206 to rise. This causes the L-shaped rod 202 to rotate around the rotating shaft 204, which in turn moves the pressure plate 301 downward. Under the action of the telescopic rod 303 and the spring 304, the test head 306 can come into contact with the workpiece. As the pressure plate 301 continues to move downward, the telescopic rod 303 shortens, the spring 304 is compressed, and the test head 306 is in close contact with the workpiece. After the test is completed, the cylinder 203 is activated, and the piston rod 206 moves downward. This causes the L-shaped rod 202 to drive the pressure plate 301 to rise. At this time, the buffer pad 302 moves away from the test head 306, and then the test head 306 moves away from the workpiece under the action of the telescopic rod 303. In this way, the workpiece can be removed.

[0035] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
