Description

Technical Field

[0001] The utility model relates to the technical field of IC carrier board testing, in particular to a rapid positioning clamping device based on an axial power matching connecting rod mechanism. Background Art

[0002] The IC carrier plays a key role in integrated circuit packaging. Its upper end receives the Pin pins of the wafer and its lower end connects to the Pin pins of the printed circuit board. In order to ensure the quality of the chip, the IC carrier must be tested for connectivity to verify whether the signal transmission is normal. During the test, the IC carrier needs to be connected to the interface board, and then connected to the test system through the interface board to achieve the conduction test of the electrical signal.

[0003] There are many pin cards on the interface board and the test system, ranging from a few hundred pins to several thousand pins. In order to ensure the accuracy of the test, the interface board and the pin card on the test system must be tightly connected to achieve reliable electrical signal conduction testing. However, in actual use, there are the following problems:

[0004] Cylinder air is cut off: During the test process, if the cylinder is suddenly cut off, the pressure between the interface board and the test system will be reduced, causing the connection between the two to become loose.

[0005] Probe rebound force: The probe will produce a certain rebound force after contact, which may also cause the connection between the interface board and the test system to be not tight enough.

[0006] Unstable connection: The above problems will cause unstable connection between the interface board and the test system, affecting the accuracy and reliability of the test results. Utility Model Content

[0025] The present utility model will be further described in conjunction with the following embodiments.

[0026] As Figures 1 to 3 can be seen, a rapid positioning and clamping device based on axial power and a connecting rod mechanism described in this embodiment includes a clamping bottom board 1 and an interface board 2 that is lifted and movably arranged on the clamping bottom board 1; the clamping bottom board 1 is provided with a hinge seat; the hinge seat is hinged with a cylinder; a connecting rod mechanism is arranged between the output end of the cylinder and the interface board 2;

[0027] The link mechanism includes a driving link 5, a driven link 6, an upper link seat 7 provided on the clamping base plate 1, a lower link seat 8 provided on the interface plate 2, and a hinge block 45 provided at the output end of the cylinder; the bottom of the driving link 5 is hinged to the hinge block 45; a first hinge rod 91 is provided between the middle of the driving link 5 and the upper link seat 7; a second hinge rod 92 is provided between the top of the driving link 5 and the top of the driven link 6; a third hinge rod 93 is provided between the bottom of the driven link 6 and the lower link seat 8;

[0028] The upper link seat 7 is provided with a hinge groove 71 through it; the first hinge rod 91 is arranged in the hinge groove 71; a first abutting surface 72 is provided on the inner wall of one end of the hinge groove 71 away from the driven link 6; the driving link 5 is provided with a second abutting surface 51 that cooperates with the first abutting surface 72. The clamping base plate 1 is arranged on the test system, and the probe of the test system is exposed on the clamping base plate 1.

[0029] Specifically, for the quick positioning and clamping device based on axial power and a link mechanism described in this embodiment, when in use, first, the cylinder is in a retracted state, as Figure 2 shown. At this time, there is a gap between the interface plate 2 and the clamping base plate 1, the probe of the test system does not contact the probe of the interface plate 2, and at this time, the second hinge rod 92 is located at the top of the first hinge rod 91 away from the first abutting surface 72.

[0030] When it is necessary for the probe of the test system to contact the probe of the interface plate 2, start the cylinder to make the output shaft of the cylinder extend. Under the action of the driving link 5 and the driven link 6, the interface plate 2 rises to abut against the clamping base plate 1. At this time, as Figure 3 shown, the second hinge rod 92 passes over the top of the first hinge rod 91, and the second hinge rod 92 is located at the top of the first hinge rod 91 close to the first abutting surface 72. At the same time, the first abutting surface 72 abuts against the second abutting surface 51. At this time, when the cylinder runs out of gas, or when the probe generates a resilience force, due to the gravity of the hinge plate and the resilience force of the probe, it is equivalent to applying a downward acting force to the second hinge rod 92. And because the first abutting surface 72 abuts against the second abutting surface 51, and the second hinge rod 92 is located at the top of the first hinge rod 91 close to the first abutting surface 72, the driving link 5 cannot move, so that the interface plate 2 and the clamping base plate 1 are locked to prevent the interface plate 2 from falling.

[0031] In the quick positioning and clamping device based on axial power and a link mechanism described in this embodiment, the first abutting surface 72 is arranged between the first hinge rod 91 and the second hinge rod 92. Through the above settings, the overall structure is more stable and reliable.

Through the above settings, it can make way for the movement of the driving connecting rod 5 and the hinge block 45.

[0035] A quick positioning and clamping device based on axial power and a connecting rod mechanism according to this embodiment. The straight line where the first hinge rod 91 and the third hinge rod 93 are located is perpendicular to the plane where the clamping bottom plate 1 is located. Through the above settings, the overall structure is made more stable and reliable.

[0036] A quick positioning and clamping device based on axial power and a connecting rod mechanism according to this embodiment. The hinge seat includes a first hinge seat 31 and a second hinge seat 32 symmetrically arranged on both sides of the clamping bottom plate 1; the cylinder includes a first cylinder 41 and a second cylinder 42 symmetrically arranged at both ends of the first hinge seat 31; the cylinder also includes a third cylinder 43 and a fourth cylinder 44 symmetrically arranged at both ends of the second hinge seat 32;

[0037] A link mechanism is respectively provided between the output ends of the first cylinder 41, the output ends of the second cylinder 42, the output ends of the third cylinder 43, and the output ends of the fourth cylinder 44 and the interface plate 2.

[0038] Specifically, in this embodiment, by setting four cylinders and four link mechanisms, the interface plate 2 can be lifted and lowered stably.
