[0030] like Figure 1 As shown, a DIP chip pin gripper device is provided for gripping the pins of a DIP chip 10. Four rows of terminals are electrically connected to the pins of the DIP chip 10 for testing the DIP chip 10. Figure 7 As shown.

[0031] like Figure 1-3 As shown, a DIP chip pin gripper device mainly consists of a parallel gripper cylinder 1, a connecting arm 1 2, a connecting arm 2 3, a terminal block fixing component 1 4, a terminal block fixing component 2 5, a terminal block 1 6, a terminal block 2 7, a terminal block 3 8, and a terminal block 4 9.

[0032] Parallel gripper cylinder 1, also known as parallel pneumatic finger, is a type of cylinder that uses compressed air as power to drive the internal piston to move, thereby driving the opening and closing action of the gripper to clamp and grasp the workpiece. It is existing technology. Parallel gripper cylinder 1 includes parallel gripper one 101 and parallel gripper two 102.

[0033] like Figure 3As shown, parallel gripper 101 is connected to connecting arm 2, and parallel gripper 202 is connected to connecting arm 3. Connecting arm 2 is connected to terminal block fixing component 4, and connecting arm 3 is connected to terminal block fixing component 5.

[0034] like Figure 1-4 As shown, terminal block 6 and terminal block 7 are mounted on terminal block fixing component 4, and terminal block 8 and terminal block 9 are mounted on terminal block fixing component 5. Terminal blocks 6, 8, 7, and 9 are arranged sequentially. Terminal blocks 6 and 8 are symmetrical to each other and are used to hold the left pin of DIP chip 10 and achieve electrical connection; terminal blocks 7 and 9 are symmetrical to each other and are used to hold the right pin of DIP chip 10 and achieve electrical connection. This avoids the pins of DIP chip 10 from deforming inward due to the lack of structural support in the middle.

[0035] like Figure 1 and 3 As shown, connecting arm 2 has a mounting groove 1, and parallel gripper 101 is placed into the mounting groove 1 and locked in the mounting groove 1 of connecting arm 2 by bolts. Connecting arm 3 has a mounting groove 2, and parallel gripper 2 102 is placed into the mounting groove 2 and locked in the mounting groove 2 of connecting arm 3 by bolts.

[0036] like Figure 3 As shown, connecting arm 2 is locked to terminal block fixing part 4 by bolts, and connecting arm 3 is locked to terminal block fixing part 5 by bolts.

[0037] like Figure 4 and 5 As shown, the terminal block fixing component 4 includes a terminal block first connecting part 401, a terminal block second connecting part 402, and a parallel guide block 403. The top end of the terminal block first connecting part 401 is integrally connected to the top end of the terminal block second connecting part 402, and a translational cavity is provided between the terminal block first connecting part 401 and the terminal block second connecting part 402. One end of the parallel guide block 403 is fixedly connected to the middle part of the terminal block first connecting part 401 by bolts, and the other end of the parallel guide block 403 clamps the middle part of the terminal block second connecting part 402 by a clamping plate. Terminal block 6 is fixedly installed on the side of the terminal block first connecting part 401, and multiple terminals of terminal block 6 are located on one side of the translational cavity. Terminal block 7 is fixedly installed on the terminal block second connecting part 402, and multiple terminals of terminal block 7 are located on the other side of the translational cavity.

[0038] like Figure 4 and 6As shown, the terminal block fixing component 2 5 includes a terminal block three connecting part 501, a terminal block four connecting part 502, and a parallel guide block 2 503. The top end of the terminal block four connecting part 502 is integrally connected to the top end of the terminal block three connecting part 501, and a translational cavity 2 is provided between the terminal block four connecting part 502 and the terminal block three connecting part 501. One end of the parallel guide block 2 503 is fixedly connected to the bottom of the terminal block four connecting part 502 by bolts, and the other end of the parallel guide block 2 503 clamps the bottom of the terminal block three connecting part 501 by a clamping plate. The terminal block three 8 is fixedly installed on the terminal block three connecting part 501, and multiple terminals of the terminal block three 8 are located at one end of the translational cavity 2. The terminal block four 9 is fixedly installed on the side of the terminal block four connecting part 502, and multiple terminals of the terminal block four 9 are located on the other side of the translational cavity 2.

[0039] The top end of the terminal block fourth connecting part 502 is integrally connected to the top end of the terminal block third connecting part 501 and is set as an integral connecting part. The parallel guide block 1 403 provides parallel guidance between the parallel guide block 2 503 and the integral connecting part.

[0040] The working process of this embodiment will be further described below:

[0041] The parallel gripper cylinder 1 serves as the power source, and the four rows of terminals act as contact pins that contact the pins of the DIP chip 10.

[0042] Parallel gripper cylinder 1 drives connecting arm 2 and connecting arm 3 to move through parallel gripper 101 and parallel gripper 2102, thereby driving the movement of 4 rows of terminals;

[0043] When the parallel gripper cylinder 1 clamps, terminal block 6 and terminal block 7 move from left to right, and terminal block 8 and terminal block 9 move from right to left; terminal block 6 and terminal block 8 form a set of clamping the left pin of DIP chip 10, and terminal block 7 and terminal block 9 form a set of clamping the right pin of DIP chip 10.

[0044] By adjusting the terminals, the left pin of DIP chip 10 is positioned between terminal block 6 and terminal block 8, while the right pin is positioned between terminal block 7 and terminal block 9. Terminal blocks 6 and 8 move relative to each other at equal speeds, ensuring they contact the left and right surfaces of the left pin of DIP chip 10 almost simultaneously. This prevents bending and deformation of the DIP chip 10's pins. Similarly, terminal blocks 7 and 9 have the same effect on the right pin of DIP chip 10.

[0045] Improvements to the gripper structure reduced the deformation of the 10 pins of the DIP chip during clamping testing.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed methods and techniques, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the shape, structure, and principle of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
