Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a high-efficiency electrical measuring mechanism. Background Art

[0002] Microchip components are a key component in electronics manufacturing. Due to their miniaturization, high integration, cost advantages, high reliability, and ease of mass production, they are widely used in a variety of electronic devices. Electrical testing of microchip components typically involves performing electrical performance tests on these components to ensure they meet specific performance standards during manufacturing and assembly. These tests are crucial to ensuring component reliability and quality.

[0003] Taking a micro-patch filter as an example, a micro-patch component is characterized by being provided with 2-4 electrodes of varying numbers, each of which is located on different sides of the filter. When performing electrical testing, existing electrical testing mechanisms usually place the micro-patch component in a fixture and then use a power source such as a driving cylinder to push a probe directly connected to a test line to contact an electrode on a single side of the electrical testing mechanism to perform electrical testing. However, existing electrical testing mechanisms can only perform electrical testing on electrodes on a single side at a time, and one electrical testing mechanism can only test one type of micro-patch component, resulting in low electrical testing efficiency and poor compatibility. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a high-efficiency electrical testing mechanism that can test micro-patch components of various specifications and improve the electrical testing efficiency of micro-patch components.

[0005] A high-efficiency electrical testing mechanism, characterized in that it includes an electrical testing mounting plate, a test fixture, a power device, multiple elastic members, a transmission device, and multiple test devices; the test fixture and the test device are arranged on the same side of the electrical testing mounting plate, and the test fixture is detachably fixed to the electrical testing mounting plate; the test fixture is used to fix the micro-patch component to be tested; the test device is provided with the elastic member in a compressed state, and the elastic member pushes the test device toward the test fixture; the transmission device includes an electrical testing cam, the power device is axially fixedly connected to the electrical testing cam, and the test device abuts against the side surface of the electrical testing cam. When the power device drives the electrical testing cam to rotate, the electrical testing cam drives the test device to move closer to or away from the test fixture.

[0006] The high-efficiency electrical testing mechanism described in the present application uses a detachable test fixture to fix the micro-patch component to be tested, and is compatible with the electrical performance test of micro-patch components of different sizes and multiple specifications. In addition, the present application provides an electrical testing cam that is axially fixedly connected to the power device and a test device connected to the compression elastic member, and the test device is abutted against the side surface of the electrical testing cam. The elastic member actively pushes the test device toward the test fixture, and the power device drives the electrical testing cam to rotate. The electrical testing cam converts the power of the power device into a linear motion of the test device that can move away from the test fixture, and further compresses the elastic member, thereby realizing the linear reciprocating motion of the test device, so that the test device contacts, tests and leaves the micro-patch component to be tested; the electrical testing cam can accurately control the start, stop, speed change, etc. of the movement of the test device, and realize simultaneous driving Multiple test devices perform complex movements to electrically measure multiple side electrodes of the micro-patch components to be tested. Compared with the existing technology of driving a power source such as a cylinder to push a probe directly connected to the test line to contact an electrode on a single side of the electrical testing mechanism, the utility model can not only realize efficient electrical testing of micro-patch components of various specifications, but also the electrical testing cam structure is relatively simple, easy to achieve high-speed movement, suitable for fast actions in electrical performance testing, small footprint, suitable for confined spaces, able to accurately control the test device, low failure rate, relatively easy maintenance and replacement, help to reduce maintenance costs, and applicable to a wider range of working environments.

[0007] Furthermore, one end of the elastic member is fixedly connected to the test device, and the other end is connected to the electrical test mounting plate or an external device. The high-efficiency electrical test mechanism of the present invention utilizes a compressed elastic member fixed between the test device and the electrical test mounting plate or the external device to automatically drive the test device toward the test fixture.

[0008] The electrical testing cam is a disc-shaped cam, comprising a base disc and several protrusions extending from the side surface of the base disc. Each of the protrusions corresponds to a test device. When the electrical testing cam rotates, several test devices synchronously abut against the corresponding protrusions or the side surface of the base disc. When a test device abuts against the protrusions, it moves away from the test fixture, further compressing the elastic member. When a test device abuts against the side surface of the base disc, the elastic member drives the test device toward the test fixture and tests the micro-patch component under test. This configuration of the electrical testing cam allows for simultaneous testing of multiple sides of the micro-patch component under test.

[0009] Furthermore, the electrical testing mounting plate is provided with a slide rail corresponding to the test device; the slide rail extends linearly toward the test fixture; the test device is mounted on the slide rail and is movable along the slide rail. The efficient electrical testing mechanism of the present invention prevents the test device from being affected by the tangential force of the electrical testing cam, causing positional displacement and thus failing to accurately test the side electrodes of the micro-patch component under test.

[0010] Furthermore, the testing device includes a probe mounting seat and a probe, the probe mounting seat is arranged on the slide rail and can move along the slide rail; the probe mounting seat abuts against the side surface of the electrical measurement cam; one end of the elastic member is fixed to the probe mounting seat, and the other end is connected to the electrical measurement mounting board or connected to an external device; the probe is arranged on one end of the probe mounting seat facing the test fixture.

[0011] Furthermore, the position of the probe on the probe mount is adjustable. When using different test fixtures to test the electrical performance of micro-patch components of different sizes, the position of the electrodes on the side of the micro-patch components may change. The present invention adjusts the position of the probe on the probe mount so that the probe contacts the electrodes on the side of the micro-patch components as required by the test, facilitating the accurate testing of micro-patch components of different sizes and specifications.

[0012] Furthermore, the probe mount includes a fine-tuning assembly comprising a first plate and a second plate movable relative to the first plate. The probe is fixed to one end of the second plate facing the test fixture. The first plate and the second plate are threadedly connected by a plurality of screws. By rotating the screws, the second plate is moved relative to the first plate along the extension direction of the screws, thereby adjusting the position of the probe on the probe mount. The fine-tuning assembly of the present invention allows the position of the probe on the probe mount to be adjusted, has a simple structure, and is easy to operate.

[0013] Furthermore, the screw includes a first screw parallel to the electrical test mounting plate and perpendicular to the probe, and a second screw parallel to the probe. Rotating the first screw allows the second plate and the probe on the second plate to move relative to the first plate along the direction in which the first screw extends, i.e., the probe can move left and right, so that the probe aligns with the electrode position on the side of the micro-patch component. Similarly, rotating the second screw allows the second plate and the probe on the second plate to move relative to the first plate along the direction in which the second screw extends, i.e., the probe can move forward and backward. This prevents the probe from being excessively "advanced" and over-pressing the electrodes of the micro-patch component, leading to measurement errors and damage to the micro-patch component, and also prevents the probe from being excessively "backward" and unable to contact the electrodes of the micro-patch component, resulting in an inability to perform electrical performance testing. Furthermore, the testing device also includes a cam follower, which is disposed on the probe mounting base; the probe mounting base abuts against the side surface of the electrical test cam via the cam follower. The high-efficiency electric measuring mechanism described in the utility model can accurately convert rotational motion into linear or angular motion by arranging a cam follower between the electric measuring cam and the probe mounting seat. It can flexibly adapt to different operation requirements according to the shape and motion parameters of the electric measuring cam, can realize various motion forms, is conducive to realizing small motions, meets the requirements of higher motion accuracy, has a simple structure, stable operation, and high reliability.

[0014] Furthermore, the transmission device also includes a speed reducer; the electrical measuring cam is axially fixedly connected to the power unit via the speed reducer; and the electrical measuring cam, the speed reducer, and the power unit are sequentially axially fixedly connected. The high-efficiency electrical measuring mechanism of the utility model, by providing a speed reducer between the power unit and the electrical measuring cam, can reduce the speed of the high-speed power source of the power unit to the required low speed to meet the operating speed requirements of the test device, while also increasing the torque of the output shaft to match different speed and torque requirements, ensuring the efficient operation of the test device, improving the efficiency of the entire electrical measuring mechanism, and reducing energy loss.

[0015] Furthermore, the high-efficiency electrical measurement mechanism further includes a base plate and a plurality of support rods. The base plate is disposed parallel to and below the electrical measurement mounting plate. The support rods are disposed between the base plate and the electrical measurement mounting plate and are perpendicularly connected thereto, forming a housing space capable of accommodating the power device and the transmission device. The power device and the transmission device are disposed within the housing space. The housing space formed by the electrical measurement mounting plate, base plate, and support rods in the high-efficiency electrical measurement mechanism of the present invention helps protect the transmission device and the power device from damage and facilitates the movement and installation of the high-efficiency electrical measurement mechanism.

[0016] Furthermore, the test fixture and the test device are mounted above the electrical test mounting plate; the electrical test mounting plate is provided with a plurality of through-holes corresponding to the test devices. The test device passes through the corresponding through-holes and abuts against the side surface of the electrical test cam, and can move linearly within the corresponding through-holes toward or away from the test fixture. As a specific embodiment, the test fixture, test device, power unit, and transmission device are mounted on different sides of the electrical test mounting plate. Through a rational structural arrangement, the efficient electrical test mechanism has good stability and is easy to use.

[0017] Furthermore, the high-efficiency electrical measuring mechanism further includes a fixed seat, the fixed seat being fixed to the lower surface of the electrical measuring mounting plate; the electrical measuring cam being fixed to the upper surface of the fixed seat and passing through the fixed seat to be axially fixedly connected to the reducer; and the reducer being fixed to the lower surface of the fixed seat and axially fixedly connected to the electrical measuring cam. The high-efficiency electrical measuring mechanism of the present invention, by providing a fixed seat, not only helps to disperse the load of the electrical measuring mounting plate, but also prevents the transmission efficiency between the electrical measuring cam and the reducer from being affected by the deadweight of the reducer and power unit, thereby meeting the operating requirements of the test device and improving the transmission efficiency of the entire electrical measuring mechanism.
