[0002] With the rapid development of new energy batteries, their applications are becoming increasingly widespread, such as in the fields of new energy vehicles, power tools, smart homes, etc. During the production process of batteries on the production line, material transfer is required for different processes. Usually, a lifting cylinder is used to drive a mechanical gripper to grab the battery for material transfer. Generally, due to the constant stroke of an ordinary lifting cylinder, it only fits one type of battery on the production line, with poor compatibility and inconvenience for the co-line production of different types of batteries on the production line. In view of this, it is necessary to invent a new type of automatic material transfer mechanism for the production line. Summary of the Invention

[0003] The purpose of this patent is to overcome the deficiencies of the prior art and provide an automatic material transfer mechanism for a production line, which can automatically change the type, adapt to different types of batteries on the production line, realize automatic material transfer, has a stable and reliable structure, high compatibility, and is convenient for the co-line production of different types of batteries on the production line.

[0004] To achieve the above object, the present patent adopts the following technical solution: An automatic material transfer mechanism for a production line, comprising a support frame body, a linear module disposed on the support frame body, and a material transfer mechanism drivingly connected to the linear module; the linear module includes a linear module frame body, a linear module driving mechanism, and a linear module output end drivingly connected to the linear module driving mechanism; the material transfer mechanism includes: a material transfer mechanism connection plate located above the linear module and connected to the linear module output end, a first lifting plate located above the material transfer mechanism connection plate, a second lifting plate located above the first lifting plate, a fixing plate located above the second lifting plate, and a third lifting plate located below the support frame body; a first lifting cylinder is disposed on the material transfer mechanism connection plate, and the first lifting cylinder is drivingly connected to the first lifting plate; a support column is disposed on the first lifting plate, and the support column passes through the second lifting plate and is connected to the fixing plate; a second lifting cylinder is disposed on the fixing plate, and the second lifting cylinder is drivingly connected to the second lifting plate. A guide shaft is disposed under the second lifting plate, a first linear bearing is disposed on the first lifting plate, and a second linear bearing is disposed on the material transfer mechanism connection plate. The guide shaft sequentially passes through the first linear bearing and the second linear bearing and is connected to the third lifting plate; an installation plate is disposed on the lower side of the third lifting plate, and at least one jaw mechanism is disposed on the installation plate; the second lifting cylinder drives the second lifting plate to drive the third lifting plate to move vertically along the first linear bearing and the second linear bearing along the guide shaft, and further drives the installation plate and the jaw mechanism to move vertically through the third lifting plate; the first lifting cylinder drives the first lifting plate to drive the support column and the fixing plate to move vertically, and further drives the second lifting cylinder on the fixing plate together with the second lifting plate and the third lifting plate to move vertically.

[0005] Specifically, the automatic material transfer mechanism of the production line in this technical solution is arranged on the production line. First, the material transfer mechanism moves vertically to grab the battery on the production line. Then, the linear module drives the material transfer mechanism to move horizontally to the position where the production line is to unload materials. Finally, the material transfer mechanism moves vertically to put down the battery, realizing the automatic material transfer of the battery on the production line. The specific principle is as follows: Initially, the battery of specification A is on the production line. The second lifting cylinder drives the second lifting plate to drive the third lifting plate to move downward vertically along the guide shaft along the first linear bearing and the second linear bearing. Then, the third lifting plate drives the mounting plate and the jaw mechanism to move downward vertically. When it moves to the height corresponding to the battery of specification A, the jaw mechanism grabs the battery of specification A. Then, it is driven by the second lifting cylinder to move upward vertically. Subsequently, the linear module drives the material transfer mechanism to move horizontally to the position where the production line is to unload materials. Finally, the material transfer mechanism moves downward vertically to put down the battery. When the battery on the production line is changed to the battery of specification B, and the height of the battery of specification B is greater than that of the battery of specification A. First, the first lifting cylinder drives the first lifting plate to drive the support column and the fixed plate to move upward vertically. Then, the second lifting cylinder on the fixed plate together with the second lifting plate and the third lifting plate are driven to move upward vertically as a whole, lifting the second lifting cylinder on the fixed plate together with the second lifting plate and the third lifting plate upward by the height difference between the battery of specification B and the battery of specification A. Then, the second lifting cylinder drives the second lifting plate to drive the third lifting plate to move downward vertically along the guide shaft along the first linear bearing and the second linear bearing. Then, the third lifting plate drives the mounting plate and the jaw mechanism to move downward vertically, and when it moves to the height corresponding to the battery of specification B, the jaw mechanism grabs the battery of specification B. The subsequent process of moving and putting down the material will not be elaborated here; the principle and process of changing the battery type from the battery of specification B to the battery of specification A are the same and will not be elaborated here; that is, through the design of the first lifting cylinder and the second lifting cylinder and their connected structures described in this application, automatic type change can be realized, adapting to different models of batteries on the production line, achieving automatic material transfer, with a stable and reliable structure, high compatibility, and facilitating the co-line production of different models of batteries on the production line.

Thus, the jaw cylinder drives the jaw to grab and load and unload the battery.

[0007] Furthermore, a buffer spring is arranged on the guide rod between the second distance separating connecting plate and the top block in this technical solution; thus, when the jaw cylinder drives the jaws to grasp the battery for loading and unloading and moves along the slide rail with the side slider of the second distance separating connecting plate, it plays a buffering role, effectively ensuring that the battery is not damaged, guaranteeing product quality, improving equipment safety, and ensuring production safety.

[0008] Furthermore, a detection sensor is arranged on the mounting plate in this technical solution for detecting the material transfer situation of the material transfer mechanism; preferably, the detection sensor is at least one of a photoelectric sensor, an opposed sensor, and a proximity switch.
