Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery tooling, in particular to a lithium battery clamping mechanism. Background Art

[0002] During the transportation process, lithium batteries need to be transported by means of clamps. The current air gripper clamp is clamped and opened by monitoring the piston stroke position in the cylinder through a magnetic switch installed in the groove of the air gripper. However, the magnetic switch in the current gripper clamp cannot effectively limit the movement of the piston. When the movement exceeds the arrival point and the air gripper arrival signal is detected, the piston still has a certain power to move beyond the predetermined stroke, resulting in a certain risk of exceeding the predetermined value in the clamping and opening state of the air gripper, thereby causing the risk of the lithium battery falling due to excessive opening of the air gripper or scratching or deformation of the lithium battery due to excessive clamping.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0025] like Figure 1-Figure 3 As shown, in one embodiment, a clamping mechanism for a lithium battery clamp is specifically a clamping mechanism for improving the safety of the lithium battery clamp. It can be understood that the safety here means minimizing the risk of the clamp's jaws, i.e., the air claws, opening excessively during the clamping process, causing the lithium battery to fall, or the risk of the lithium battery being scratched or deformed due to excessive clamping.

[0026] The specific structure includes:

[0027] The clamp body 1 is an air clamp, which includes a cylinder as a driving mechanism and two side guard plates 12 connected to the cylinder. In the prior art, the cylinder can drive the relative movement of the two side guard plates 12 to achieve the switching between the clamping state and the opening state;

[0028] At least one sheet metal part 2 capable of linear motion is fixed to the surface of the clamp body 1. Specifically, the sheet metal part 2 is connected to the vertical connection part of the clamp body 1, and the sheet metal part 2 can move synchronously with the side guard plate 12. The sheet metal part 2 is a long strip structure, which presents an "L"-shaped structure, including a connecting portion 21 fixedly connected to the clamp body 1 and an extension portion 22 integrally formed with the connecting portion 21, and the end of the extension portion 22 presents a curved structure, which is located in the groove between the two photoelectric sensors 4.

[0029] As for the photoelectric sensor 4, it is preferably a slot-type photoelectric sensor 4. In this embodiment, two slot-type photoelectric sensors 4, such as the first sensor 41 and the second sensor 42, are on the same horizontal line. The movement of the air gripper fingers 11 is controlled by the detection signals of the two photoelectric sensors 4, and the opening and clamping states of the air gripper are reflected by the position of the sheet metal part 2. The accuracy of the in-place signal is ensured, while the possibility of exceeding the expected value is avoided, and the movement stroke is limited to reduce or avoid the risk of the lithium battery falling due to excessive opening of the clamp, i.e., the air gripper, or scratching or deformation of the lithium battery due to excessive clamping. Specifically, by making the sheet metal part 2 within the area of ​​the two slot-type photoelectric sensors 4, the position of the sheet metal part 2 is determined by the detection signals of the slot-type photoelectric sensors 4, thereby determining whether the clamp is in an open or closed position.

[0030] For the installation of the photoelectric sensor 4, a clamp fixing plate 5 is installed at the upper end of the clamp body 1, and the bottom of the clamp fixing plate 5 is connected to the first fixing plate 3 extending downward, and two photoelectric sensors 4 are fixed to the surface of the first fixing plate 3 by screws. Preferably, there is a gap, i.e., a distance, between the two photoelectric sensors 4, and the width of the gap is not greater than the width of the end of the sheet metal 2, so as to avoid the sheet metal 2 being in a completely empty position, so that the photoelectric sensor 4 cannot make a correct judgment.

[0031] Furthermore, when it is necessary to change the model to adapt to different battery sizes, it can be completed by replacing the air gripper finger 11, which has lower replacement cost, convenient debugging, reduced labor hours, and higher compatibility.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
