[0005] Another embodiment, the second mounting plate and third mounting plate between being equipped with guide pillar, the guide pillar has part and extends in the rear end portion outside the third mounting plate, the pull rod is passed in the guide pillar. Make pull rod move more accurate and smooth.

[0006] Another embodiment, the clamping jaw includes the first clamping plate and the second clamping plate symmetrically arranged, the first clamping plate and the second clamping plate are respectively rotationally connected between the third mounting plate and the second mounting plate and both have tail portion extending towards front side, the tail portion of the first clamping plate and the second clamping plate is hinged by pin, the pin is simultaneously passed on the pull rod.

[0007] In another embodiment, the front end of the pull rod is provided with a sensing head for detecting whether there is a workpiece, and the front end of the pull rod has an oblong hole that penetrates its circumference and extends in the front-rear direction, with the pin disposed in the oblong hole. When the first slide moves forward, the front end of the first slide exerts no force on the second slide. When the telescopic component is not activated, the spring causes the pull rod to extend forward and drive the grippers to open to both sides, with its sensing head located between the first and second clamping plates. When the sensing head detects a workpiece, the telescopic component retracts, causing the first slide to move backward. The first slide then drives the second slide to move backward, which in turn drives the pull rod to move backward and completely exit between the first and second clamping plates. At this time, the front end of the oblong hole contacts the pin, and then the pull rod continues to move backward, and the first and second clamping plates clamp together to complete the clamping action.

When the telescopic component is activated, the first slide plate drives the second slide plate to move backward, which in turn drives the pull rod to move backward and finally drives the gripper to clamp. The detection and clamping processes are completed in one action, which has high efficiency and fast production speed. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the gripper structure of this utility model when it is clamping. Detailed Implementation

[0012] See Figure 1 and Figure 2As shown, the robotic arm for the battery casing stretching device includes a first mounting plate 1, a telescopic member 2 mounted on the first mounting plate 1, a second mounting plate 3 with its rear end mounted on the first mounting plate 1, a gripper mounted on the front end of the second mounting plate 3, and a third mounting plate 4 mounted on the front end of the second mounting plate 3 and clamping the gripper between the second mounting plate 3 and itself. The robotic arm also includes a first sliding plate 5 and a second sliding plate 6 slidably connected to the second mounting plate 3, a pull rod 7 movable in the front-rear direction and passing through the second mounting plate 3 and the third mounting plate 4, and a spring 8 that makes the pull rod 7 always tend to move towards the front. The rear end of the first sliding plate 5... The first slide plate 5 is frame-shaped and is connected to the telescopic component 2. It frames the second slide plate 6 inside. When the first slide plate 5 moves forward, the front end of the first slide plate 5 exerts no force on the second slide plate 6, and its front end has a notch 15 for the pull rod 7 to pass through. The front end of the pull rod 7 is connected to the gripper, and the rear end of the pull rod 7 is fixedly connected to the second slide plate 6. The spring 8 is located between the third mounting plate 4 and the second slide plate 6. When the telescopic component 2 is not activated, the spring 8 causes the pull rod 7 to extend forward and drives the gripper to open to both sides. When the telescopic component 2 is activated, the first slide plate 5 drives the second slide plate 6 to move backward, which in turn drives the pull rod 7 to move backward and finally drives the gripper to clamp.

[0013] Specifically:

[0014] A guide post 9 is provided between the second mounting plate 3 and the third mounting plate 4. The guide post 9 partially extends beyond the rear end of the third mounting plate 4, and the pull rod 7 passes through the guide post 9. This allows the pull rod 7 to move more accurately and smoothly. The gripper includes a first clamping plate 10 and a second clamping plate 12 arranged symmetrically. The first clamping plate 10 and the second clamping plate 12 are respectively rotatably connected between the third mounting plate 4 and the second mounting plate 3, and both have tails extending forward. The tails of the first clamping plate 10 and the second clamping plate 12 are hinged together by a pin 11, which also passes through the pull rod 7. The front end of the pull rod 7 is provided with a sensing head 13 for sensing whether there is a workpiece, and the front end of the pull rod 7 has a waist-shaped hole 14 that penetrates its circumference and extends in the front-rear direction. The pin 11 is located in the waist-shaped hole 14. The telescopic component 2 is a cylinder or a hydraulic cylinder.

[0015] The principle of this utility model is as follows: When the telescopic component 2 is not activated, the spring 8 causes the pull rod 7 to extend forward and drive the gripper to open to both sides. Its sensing head 13 is located between the first clamping plate 10 and the second clamping plate 12. When the sensing head 13 senses the presence of a workpiece 0, the telescopic component 2 retracts, causing the first sliding plate 5 to move backward. The first sliding plate 5 drives the second sliding plate 6 to move backward, which in turn drives the pull rod 7 to move backward and completely exit between the first clamping plate 10 and the second clamping plate 12. At this time, the front end of the waist-shaped hole 14 contacts the pin 11. Then the pull rod 7 continues to move backward, and the first clamping plate 10 and the second clamping plate 12 clamp together to complete the clamping action. If it is necessary to release the gripper, the telescopic component 2 can be closed, and the spring 8 will drive all components to reset.
