Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and more specifically, to a high-reliability component testing mechanism. Background Technology

[0002] In current component testing mechanisms, to facilitate the connection of test contacts to the component box, the test contacts are usually connected to the contacts of the component under test via conductive adhesive. After long-term use, the conductive particles in the conductive adhesive may be squeezed, displaced, or worn due to repeated contact. This leads to a decrease in the effective conductive particle density at the contact point, a gradual increase in contact resistance, and instability, requiring timely replacement. Failure to replace the conductive adhesive in time can actually affect the connection of the component.

[0003] Existing technologies lack a dynamic adjustment mechanism for the wear area of ​​conductive adhesive, which limits testing efficiency and reliability. Utility Model Content

[0004] The purpose of this invention is to provide a highly reliable component testing mechanism that dynamically adjusts the contact position of the conductive adhesive, evenly disperses wear, significantly extends the service life of the conductive adhesive, and improves the stability and continuity of testing.

[0009] The present invention is further configured such that: the Y-axis moving component includes a Y-axis servo motor, a Y-axis eccentric wheel, and a Y-axis limiting block; the Y-axis eccentric wheel is fixedly connected to the output end of the Y-axis servo motor; the Y-axis limiting block has a Y-axis limiting groove that matches the Y-axis eccentric wheel; through the cooperation of the Y-axis eccentric wheel and the Y-axis limiting block, the rotation of the Y-axis servo motor can drive the Y-axis limiting block to move in the Y-axis direction.

[0010] The present invention is further configured such that: an X-axis moving plate is fixedly connected to one end of the test connecting plate away from the conductive adhesive; the X-axis moving plate is connected to the X-axis limiting block through the X-axis base plate connecting plate; a Y-axis moving plate is fixedly connected to the Y-axis limiting block; the X-axis moving plate is connected to the Y-axis moving plate through a linear guide rail along the X-axis; and the Y-axis moving plate is connected to the frame through a linear guide rail along the Y-axis.

[0011] In summary, this utility model has the following beneficial effects:

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: High-reliability component testing mechanism, such as Figure 1 As shown, one end of the test connection plate 3 is provided with conductive adhesive 12, and the other end of the test connection plate 3 is connected to the X-axis moving component 4 and the Y-axis moving component 8. The X-axis component includes an X-axis servo motor 5, an X-axis eccentric wheel 6 fixed to the motor output shaft, and an X-axis limiting block 7 that cooperates with the eccentric wheel. When the X-axis servo motor 5 rotates, the eccentric wheel pushes the limiting block to move back and forth along the X-axis, thereby driving the test connection plate 3 and the conductive adhesive 12 to move synchronously.

[0018] The Y-axis moving component 8 adopts the same principle as the X-axis moving component 4, and the X-axis limiting groove and the Y-axis limiting groove are perpendicular to each other.

[0019] After the testing mechanism tests a certain number of components, the control system starts the servo motor to drive the conductive adhesive 12 to move a set distance along the X / Y axis, so that the unused new area is aligned with the test contact.

[0020] For example: initially positioned at coordinates (0,0); after wear, moved to position (5mm,5mm). This cycle fully utilizes the entire surface of the conductive adhesive 12, allowing for timely replacement of the new area of ​​the conductive adhesive 12 with the contact, ensuring a consistently good connection between the component and the contact.

[0021] The lower surface of the test platform 2 is equipped with a Z-axis adjustment assembly, which consists of a Z-axis support plate 14Z and a Z-axis adjustment plate 15 nested together by a slide rail. The support plate has a round hole, and the adjustment plate has a waist hole. Bolts pass through the two holes and are locked in place. When the bolts are loosened, the waist hole provides Z-axis displacement margin, and the height of the test platform 2 is adjusted to maintain optimal contact pressure between the contact point and the conductive adhesive 12.

[0022] Furthermore, the bottom of the Z-axis adjustment plate 15 is connected to the manual XY slide 16, which allows for fine-tuning of the position of the test platform 2 in the horizontal plane via a knob, compensating for assembly errors and ensuring that all contacts are fully bonded to the conductive adhesive 12.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
