[0032] like Figure 1 As shown, the present invention provides a positive and negative double-clamp terminal clamp, comprising:

[0033] The rotating assembly 30 is provided with a rotating shaft 34 and a positive limiting portion and a reverse limiting portion for limiting the rotation angle of the rotating shaft 34;

[0034] A clamping assembly 50, which is connected to the rotating shaft 34 and opens and closes to clamp the terminal;

[0035] The rotating shaft 34 is provided with a rotational driving force by a driving member; the clamping assembly 50 is driven by the rotating shaft 34 to move between the forward limiting portion and the reverse limiting portion to achieve forward and reverse clamping of the terminal.

[0036] Furthermore, the driving member is a rotary cylinder 45 .

[0037] In the above technical solution, the specific structure of the driving member is not limited, as long as it can drive the rotating shaft 34 to realize forward and reverse rotation. Specifically, the driving member includes but is not limited to the rotating cylinder 45 and the forward and reverse motor. When in use, first place the clamping assembly 50 in the initial position, that is, the middle position of the forward limit part and the reverse limit part, then move the terminal clamp to the position where the terminal needs to be clamped, control the clamping assembly 50 to clamp the terminal, and then move the terminal clamp to the vicinity of the installation rail. According to the clamping type of the terminal to be installed, control the driving member to drive the rotating shaft 34 to rotate forward or reverse, and the rotating shaft 34 drives the clamping assembly 50 to rotate until it is positioned by the forward limit part or the reverse limit part, and then move the terminal clamp to the terminal clamping position to perform terminal clamping. After the clamping is completed, control the clamping assembly 50 to release the terminal to complete a terminal clamping process.

[0038] The terminal clamp provided by the present invention can control the clamping assembly to rotate forward or reversely by a predetermined angle according to the clamping type of the terminal to be installed, thereby realizing the forward and reverse clamping of the terminal.

[0039] In another technical solution, Figure 2 , 3 As shown, the positive and negative double-clamp terminal clamp, the rotating assembly 30 also includes a rotating shaft mounting plate 41, the rotating shaft 34, the positive limit part and the reverse limit part are all mounted on the rotating shaft mounting plate 41; the initial limit part is arranged between the positive limit part and the reverse limit part, and is movably mounted on the rotating shaft mounting plate 41; wherein the initial limit part is used to realize the initial state positioning of the rotating shaft 34; the positive limit part is used to realize the positive rotation angle positioning of the rotating shaft 34, and the positive rotation angle is rotated clockwise by a predetermined angle relative to the initial state; the reverse limit part is used to realize the reverse rotation angle positioning of the rotating shaft 34, and the reverse rotation angle is rotated counterclockwise by a predetermined angle relative to the initial state. Here, an initial limit part is added between the positive and reverse limit parts to position the initial state of the rotating shaft, so as to facilitate the precise control of the clamping assembly to clamp the terminal.

[0040] In another technical solution, Figure 2 , 3As shown, the positive and negative double-clamp terminal clamp, the positive limit part and the reverse limit part are both rubber rollers 35 protruding from the rotating shaft mounting plate 41.

[0041] In another technical solution, Figure 2 , 3 As shown, the initial limit part of the forward and reverse double-clamp terminal clamp is two positioning pins 36 that cooperate with each other. Any positioning pin 36 is driven by a needle cylinder 44 to extend or retract the rotating shaft mounting plate 41. When the terminal is positioned in the initial state of forward clamping, the needle cylinder 44 drives the positioning pin 36 close to the forward limit part to extend and the other positioning pin 36 to retract. When the terminal is positioned in the initial state of reverse clamping, the needle cylinder 44 drives the positioning pin 36 close to the reverse limit part to extend and the other positioning pin 36 to retract. Here, the two positioning pins cooperate to perform differentiated initial state positioning according to the clamping direction of the terminal, so as to facilitate the automatic control of the forward and reverse clamping of the terminal clamp.

[0043] In another technical solution, Figure 2 , 3As shown, the forward and reverse double-card terminal clamp, the rotating component 30 also includes a rotation angle detection mounting block 32, which is mounted on the rotating shaft mounting plate 41; three photoelectric switches 33, which are mounted on the rotation angle detection mounting block 32, including a first photoelectric switch 1, a second photoelectric switch 1 and a third photoelectric switch 1 arranged in sequence; the clamping component 50 is provided with an angle light blocking plate 59, which rotates synchronously with the rotating shaft 34; wherein, when the rotating shaft 34 rotates to a forward rotation angle, the first photoelectric switch 1 is triggered by the angle light blocking plate, and the forward rotation angle positioning signal of the rotating shaft 34 is fed back; when the rotating shaft 34 rotates to an initial state, the second photoelectric switch 1 is triggered by the angle light blocking plate, and the initial state positioning signal of the rotating shaft 34 is fed back; when the rotating shaft 34 rotates to a reverse rotation angle, the third photoelectric switch 1 is triggered by the angle light blocking plate, and the reverse rotation angle positioning signal of the rotating shaft 34 is fed back. Here, three photoelectric switches and angle light shielding plates are arranged in cooperation to realize photoelectric positioning detection of the rotation angle of the rotating shaft. On the one hand, it can cooperate with the mechanical limits of the forward limit part, the reverse limit part and the initial limit part to improve the positioning accuracy. On the other hand, according to the feedback signal of the photoelectric switch, the drive part can be controlled to perform corresponding actions to optimize the automatic control of the terminal clamp.

Here, the air gripper controls the opening and closing of the terminal clamping wall to realize the clamping of the terminal; the limit stopper cooperates with the initial limit part, the forward limit part and the reverse limit part to realize the positioning of the rotating shaft at different rotation angles, so that the terminal clamp has higher stability and improves the flexibility of the terminal clamp.

[0045] Furthermore, a plastic block 57 is installed at the lower part of the terminal clamping arm 55, and the plastic block 57 extends to the side where the terminal is clamped.

Here, the preset distance is greater than the maximum retraction distance of the air gripper and is less than the maximum retraction distance of the clamping terminal to be installed. The maximum retraction distance of the clamping terminal to be installed refers to the retraction distance of the air gripper when clamping the terminal to be installed with the minimum size. By adding a photoelectric switch 2 and a light shield 2, it is possible to timely know whether the terminal clamping is successful, reduce the invalid operation of the terminal clamp when the terminal clamping fails, and optimize the automatic control of the terminal clamp.
