[0036] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0037] Please refer to Figures 1 to 7 , an automatic plug-in transfer mechanism of a test fixture of the present invention includes a fixed baffle 1, a telescopic assembly 2 and a plug-in control component 3, and the telescopic assembly 2 is used to convey an external fixture 100;

[0038] The plug-in control assembly 3 includes a swing driving member 31, a connecting plate 32 and a movable baffle 33, wherein the movable baffle 33 is connected to the connecting plate 32, and the movable baffle 33 and the connecting plate 32 are arranged to intersect, and the swing driving member 31 is arranged on the telescopic assembly 2, and the swing driving member 31 drives the connecting plate 32 to swing in a vertical direction so that the upper surface of the movable baffle 33 is higher than the lower surface of the external fixture 100, or the upper surface of the movable baffle 33 is lower than the lower surface of the external fixture 100;

[0039] The fixed baffle plate 1 is arranged on the telescopic assembly 2 , and the fixed baffle plate 1 is parallel to the movable baffle plate 33 and is spaced apart from each other.

[0040] Specifically, in the present embodiment, a jig 100 is installed with a plurality of test sockets 200, and a test socket 200 fixes an external chip to be tested, and the connecting plate 32 and the movable baffle 33 are mutually vertically connected structures. Preferably, the connecting plate 32 and the movable baffle 33 are integrally constructed and are in a transverse L shape. In the initial state, the connecting plate 32 is in a horizontal state, and the movable baffle 33 is in a vertical state. The external jig 100 equipped with a plurality of chips is placed on the telescopic component 2, and the upper end surface of the movable baffle 33 is higher than the lower end surface of the external jig 100, so that the external jig 100 is fixed and limited in the horizontal direction by the movable baffle 33 and the fixed baffle 1, and then the telescopic component 2 transports the jig 100 to the external detection station in the horizontal direction, and the swing driving member 31 drives the connecting plate 32 downward Swing, the movable baffle 33 swings downward synchronously. When the upper end surface of the movable baffle 33 is lower than the lower end surface of the external fixture 100, the telescopic component 2 continues to push the external fixture 100 to move forward until it is connected with the external detection mechanism, completing the automatic plug-in processing requirements of the external fixture 100 and the detection mechanism. When the detection is completed, the swing drive part 31 drives the connecting plate 32 to swing upward, and the movable baffle 33 swings upward synchronously. The upper end surface of the movable baffle 33 is higher than the lower end surface of the external fixture 100, so that the movable baffle hooks the external fixture 100, and the external fixture 100 is fixed between the movable baffle 33 and the fixed baffle 1. The telescopic component 2 moves in the opposite direction to pull the external fixture 100 out of the external detection mechanism, and the external fixture 100 is sent to the next station under the action of the telescopic component 2.

[0041] By setting the plug-in control component 3 and the fixed baffle 1 on the telescopic component 2, the plug-in control component 3 includes a swing driving part 31, a connecting plate 32 and a movable baffle 33. After the telescopic component 2 sends the external fixture 100 to the external detection station, the swing driving part 31 drives the connecting plate 32 and the movable baffle 33 to swing downward synchronously, and the movable baffle 33 disengages from the external fixture 100. Under the push of the telescopic component 2, the fixture 100 is inserted into the external detection mechanism. When the detection is over, the swing driving part 31 drives the connecting plate 32 and the movable baffle 33 to swing upward, so that the movable baffle 33 hooks the external fixture 100, and under the action of the telescopic component 2, the external fixture 100 is disengaged from the external detection mechanism to achieve the pulling-out effect, realizing automatic plugging and unplugging and improving the purpose of production automation.

[0042] The swing driving part 31 includes an upper pressing mechanism 311 and a reset mechanism 312. The upper pressing mechanism 311 is arranged on the telescopic component 2 and above the connecting plate 32, and the reset mechanism 312 is arranged on the telescopic component 2 and below the connecting plate 32. Preferably, the upper pressing mechanism 311 is above the connecting plate 32 to drive the connecting plate 32 to swing downward, so that the upper end face of the movable baffle 33 is lower than the lower end face of the external fixture 100, and the restriction of the movable baffle 33 on the external fixture 100 is lost. The reset mechanism 312 is arranged below the connecting plate 32 to drive the connecting plate 32 to swing upward, so that the upper end face of the movable baffle 33 is higher than the lower end face of the external fixture 100 to achieve the purpose of hooking the fixture 100.

[0043] The upper pressing mechanism 311 includes a push plate driving part 3111, a push plate 3112 and a lower convex block 3113. The push plate driving part 3111 is arranged on the telescopic component 2 and drives the push plate 3112 to move;

[0044] The connecting plate 32 is provided with an upper convex block 34. The push plate driving member 3111 drives the push plate 3112 to move, so that the lower convex block 3113 approaches or moves away from the upper convex block 34. When the push plate 3112 moves in the horizontal direction, the lower convex block 3113 approaches the upper convex block 34 and applies pressure to the upper convex block 34, causing the connecting plate 32 to swing downward. The movable baffle 33 swings downward synchronously. The upper surface of the movable baffle 33 is lower than the lower surface of the external jig 100, losing the limit on the external jig 100. When the push plate driving member 3111 drives the push plate 3112 to continue moving in the horizontal direction, the lower convex block 3113 moves away from the upper convex block 34. Under the action of the reset mechanism 312, the connecting plate 32 and the movable baffle 33 are reset. The upper surface of the movable baffle 33 is higher than the lower surface of the external jig 100, and the movable baffle 33 hooks the external jig 100. Preferably, the push driving member 3111 adopts a gas strut structure to drive the push plate 3112 to move in the horizontal direction, so that the lower convex block 3113 on the lower surface of the push plate 3112 gradually approaches the upper convex block 34, presses the upper convex block 34, and moves away from the upper convex block 34, that is, the purpose of the downward swing and reset of the movable baffle 33 is achieved.

[0045] The lower convex block 3113 is provided with a first inclined surface 31131, and the upper convex block 34 is provided with a second inclined surface 341. The first inclined surface 31131 cooperates with the second inclined surface 341. Preferably, the number of the first inclined surfaces 31131 is two. The two first inclined surfaces 31131 are located on opposite sides of the lower convex block 3113 and are arranged along the telescopic direction of the telescopic assembly 2. The number of the second inclined surfaces 341 is two. The two second inclined surfaces 341 are located on opposite sides of the upper convex block 34 and are arranged along the telescopic direction of the telescopic assembly 2, so that during the movement of the push plate 3112, the lower convex block 3113 and the upper convex block 34 are in a state of approaching, pressing, pressing down, and moving away, that is, the swinging effect of the connecting plate 32 is achieved.

[0046] Preferably, the cross section of the lower convex block 3113 is trapezoidal in an inverted shape, and the cross section of the upper convex block 34 is trapezoidal in a positive shape. That is, the two first inclined surfaces 31131 of the lower convex block 3113 are symmetrically arranged, and the two second inclined surfaces 341 of the upper convex block 34 are symmetrically arranged, realizing the swing and reset of the movable block 33 during the movement of the push plate 3112.

[0047] The reset mechanism 312 includes a limit member 3121, a guide post 3122, and a spring 3123. One end of the guide post 3122 is fixedly connected to the telescopic assembly 2. The guide post 3122 is slidably connected to the connecting plate 32. The limit member 3121 is provided at the other end of the guide post 3122 and is located above the connecting plate 32. The spring 3123 is sleeved on the guide post 3122, and the spring 3123 is located between the connecting plate 32 and the telescopic assembly 2. Preferably, the connecting plate 32 is provided with a through hole for the guide post 3122 to pass through. One end of the guide post 3122 is fixed to the telescopic assembly 2. The spring 3123 is sleeved on the guide post 3122 and is located between the connecting plate 32 and the telescopic assembly 2. When the connecting plate 33 is pressed down by the lower convex block 3113, the spring 3123 is compressed. When the lower convex block 3113 moves away from the upper convex block 34, the pressure applied to the connecting plate 33 disappears, and the spring 3123 releases elastic force to push the connecting plate 33 to reset. The setting of the limit member 3121 makes the swing angle of the connecting plate 33 within a preset range, meeting the production requirements.

[0048] The telescopic assembly 2 includes a first driving member 21, a first movable plate 22, a second driving member 23, and a second movable plate 24. The first driving member 21 is provided on the mounting plate 5 and drives the first movable plate 22 to move. The second driving member 23 is provided on the first movable plate 22 and drives the second movable plate 24 to move. The upper pressing mechanism 311 is provided on the second movable plate 24. The reset mechanism 312 is provided on the second movable plate 24 and drives the connecting plate 32 to reset. By two-stage contraction, the problem of a long stroke in a small space is solved, and the purpose of flexibly controlling the stroke is achieved.

[0049] The fixed baffle 1 is provided on the second movable plate 24. The second driving member 23 drives the second movable plate 24 to move, and the fixed baffle 1 moves synchronously, pushing the external fixture 100 towards the external detection mechanism. The fixed baffle 1 and the movable baffle 33 jointly clamp the external fixture to achieve the purpose of conveying and transferring.

[0050] The automatic plug-in and transfer mechanism of the test fixture 100 further includes side guide platforms 4. The side guide platforms 4 are provided on the telescopic assembly 2. The upper surface of the side guide platforms 4 is higher than the upper surface of the connecting plate 32.

The rotation driving member 6 drives the mounting plate 5 to rotate. The telescopic assembly 2 is provided on the mounting plate 5. The rotation driving member 6 drives the mounting plate 5 to rotate, synchronously driving the telescopic assembly 2 to rotate a preset angle to receive the external fixture 100 and discharging the detected external fixture 100 to the next station.
