Description

Technical Field

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

[0002] Lithium battery grippers are a common mechanism used to pick and place lithium batteries. Currently, the grippers are installed with a spring-loaded guide shaft on each side, mounted in a flanged linear bearing. The linear bearings are mounted below the gripper's mounting plate and the mounting platform, while the gripper body is directly fixed to the gripper's mounting plate. The linear bearings act as guides, connecting the mounting platform to the gripper's mounting plate. The springs sleeved in the guide shafts act as buffers. However, due to their inherent characteristics, linear bearings have a certain amount of internal play. The movement of the linear bearings is controlled by ball bearings, which inherently have low friction. During high-speed motion of the robot arm, the guide shafts will shift due to inertia. Furthermore, the springs sleeved on the guide shafts will also cause movement of the guide shafts within the linear bearings, reducing the vertical accuracy of the fixture. Utility Model Content

[0003] The purpose of the present utility model is to solve the above problems and provide a lithium battery clamp buffer mechanism.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A lithium battery clamp buffer mechanism, characterized by comprising a mounting platform;

[0006] A guide shaft, the top end of which is fixed to the bottom end of the mounting platform;

[0009] A plurality of elastic buffer members are arranged between the mounting platform and the fixing block;

[0010] A plate extends downward from both ends of the fixing block, and the plate is connected to the cylinder.

[0011] As a further description of the above technical solution, the elastic buffer is a connecting block with a spring sleeved on the outside, and the elastic buffer is used to provide a spring pre-tightening force to the mounting platform and the fixing block.

[0012] As a further description of the above technical solution, the cylinder is mounted on the upper surface of a horizontal mounting plate, and the two plates are also connected to the upper surface of the mounting plate.

[0013] As a further description of the above technical solution, the linear bearing is arranged in the space between the two oppositely arranged plates.

[0014] As a further description of the above technical solution, the linear bearing is not directly connected to the cylinder.

[0015] As a further description of the above technical solution, the guide shaft is arranged parallel to the elastic buffer and several elastic buffers are symmetrically distributed on both sides of the fixed block center line, and the guide shaft is symmetrically distributed on both sides of the fixed block center line.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] like Figure 1-Figure 2 As shown, in one embodiment, a lithium battery clamp buffer mechanism, its specific structure includes:

[0025] The mounting platform 1 is a plate-like structure with an opening formed on it. Through the opening, the guide shaft 2 below can be fixedly connected to the bottom of the mounting platform 1. The flange of the flange-type linear bearing is connected to the fixed block 3. The guide shaft is inserted into the flange-type linear bearing. The flange-type linear bearing is mounted on the fixed block 3. A plurality of elastic buffers 4 are provided between the mounting platform 1 and the fixed block 3, preferably in two groups. Preferably, the elastic buffer 4 is a connecting block with a spring sleeve on the outside. The top of the connecting block is fixed to the mounting platform 1 and passes through the pre-punched hole of the fixed block 3. The spring sleeved on the periphery of the connecting block acts as a buffer. When the spring contracts, the connecting block can move downward through the pre-punched hole of the fixed block 3. There is a hard limit of the fixed block near the air gripper finger to prevent the connecting block from moving excessively and hitting the finger. In summary, the fixing effect of the two connecting blocks can make the force of the entire clamp more balanced, and the spring sleeved on the connecting block directly provides spring preload for the mounting platform 1 and the fixed block 3, reducing the shaking of the clamp during operation and acting as a buffer.

[0026] The linear bearing in this application only needs to play the role of vertical guidance of the clamp. Compared with the existing equipment that only relies on the spring outside the linear bearing, after long-term use, the linear bearing will bear too much force and the accumulated deviation value will be too large. Moreover, the spring is placed outside the linear bearing, which will also affect the spring when the linear bearing moves up and down. After long-term use, the existing design has a significant decrease in the spring buffering effect. Since the linear bearing in this application has a connecting block with a spring to share the force, the linear bearing mainly only plays the role of vertical guidance, and the service life of the spring is increased.

[0027] A plate 5 extends downward from each end of the fixed block 3. The plate 5 is connected to the cylinder 8. Specifically, the plate 5 is connected to each end of the mounting plate 6 used to support the cylinder 8. The cylinder 8 is mounted on the upper surface of the horizontal mounting plate 6. The fixed block 3, the two plates 5 and the mounting plate 6 form a frame structure, and the clamp body is disposed within this frame structure. The clamp body is not connected to the linear bearing, so that the linear bearing only serves as a vertical guide for the clamp. It should be noted that the linear bearing and the connecting block are symmetrically distributed around the center of the fixed block 3, making the overall force more uniform.

[0028] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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 is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
