Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to a quick-change tray mechanism for an AGV vehicle. Background Art

[0002] In the new energy vehicle industry, power batteries are a main energy supply method, and power batteries are generally presented in the form of Pack (i.e., battery pack). The battery pack is composed of battery modules. For example, different products such as blade batteries, cylindrical batteries, and square batteries are arranged in modules in the Pack box.

[0003] With the rapid development of electric vehicles, as an important component of new energy vehicles, the battery pack has received more and more attention from enterprises. The process of putting the battery cell modules into the box is an important process in the battery pack assembly process. In the existing process of putting the battery modules into the box or cabinet, one production method is to use a robot suction cup to complete. The suction cup directly applies an attractive force to the battery module for adsorption. After transporting it to the corresponding position, the battery module is released to the designated position of the box by the suction cup to achieve putting into the box.

[0004] Since the specifications of the battery cells are diverse, in order to match different specifications of the batteries during the production process, the suction cups are also designed to match multiple specifications of the battery cells. In the automated production line for battery assembly, the suction cups need to be flexibly replaced according to different requirements of the battery cells. The currently adopted solution is to set up a fixed changeover table. First of all, since this changeover table is fixed in position, it needs to occupy a certain space on the automated production line, resulting in low space utilization rate. Secondly, due to the limited area of the changeover table, the number of suction cups that can be accommodated on it is limited, resulting in low product compatibility. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the method of using a changeover table to replace the suction cup for adsorbing the battery cells in the prior art is limited by the space size and results in low compatibility.

[0006] To solve the above technical problem, the utility model provides a quick-change tray mechanism for an AGV vehicle, including: an AGV vehicle as a power source; a moving vehicle frame body provided with a connection component, and the AGV vehicle is connected to the moving vehicle frame body through the connection component for driving the moving vehicle frame body to move; a tray fixedly connected to the moving vehicle frame body; a support plate fixedly arranged on the tray, and a plurality of positioning pins are arranged on the support plate; a quick-change disk connected to the support plate through a plurality of positioning pins, and the quick-change disk is used for placing the suction cup to be replaced. The quick-change tray mechanism for an AGV vehicle of the utility model has a simple structure, improves the utilization rate of the factory building space layout, has higher flexibility than the changeover table, and improves product compatibility.

The mounting block is fixedly arranged on the moving cart frame. The first limiting block is arranged on the mounting block through the first rotating shaft, and the second limiting block is arranged on the mounting block through the second rotating shaft. The first spring is arranged between one end of the first limiting block and the mounting block, and the second spring is arranged between one end of the second limiting block and the mounting block. The first limiting block and the second limiting block are used to limit the connecting column on the mounting block to realize the connection between the AGV cart and the moving cart frame.

[0009] In an embodiment of the present utility model, a U-shaped groove is provided on the mounting block, a washer is provided on the bottom surface of the U-shaped groove, the cross-section of the washer is semi-circular, and the connecting column is placed inside the washer to realize the connection between the AGV cart and the moving cart frame.

[0010] In an embodiment of the present utility model, a first step and a second step are provided on the inner wall of the U-shaped groove, the first rotating shaft is arranged on the first step, and the second rotating shaft is arranged on the second step.

[0011] In an embodiment of the present utility model, the first limiting block and the second limiting block are symmetrically arranged and are arranged in an "eight" shape. When the first spring and the second spring respectively provide elastic restoring forces for the first limiting block and the second limiting block, the large-end opening between the first limiting block and the second limiting block faces the side of the opening of the U-shaped groove, and the small-end opening between the first limiting block and the second limiting block faces the side of the washer.

[0012] In an embodiment of the present utility model, the gap width of the small-end opening between the first limiting block and the second limiting block is smaller than the diameter of the connecting column.

[0013] In an embodiment of the present utility model, the moving cart frame is a rectangular frame, and universal rollers are provided at the four corner positions of the lower end of the moving cart frame.

[0014] In an embodiment of the present utility model, guide plates are provided on two opposite outer walls of the moving cart frame. The guide plates are rectangular flat plates, and bending portions are provided at the ends in the length direction of the guide plates, and the bending portions are bent towards the inner side of the moving cart frame.

[0015] In an embodiment of the present utility model, positioning holes are provided at the four corner positions of the tray, and the positioning holes are connected to positioning columns to realize the locking of the moving cart frame.

[0016] The above technical solution of the present utility model has the following beneficial effects compared with the prior art:

[0017] For the AGV cart quick-change pallet mechanism of the present utility model, when the three-axis gantry robot needs to change models, the AGV cart pulls the mobile cart frame to move to the change model position. The robot places the old suction cup at the reserved position of the quick-change disk, and then replaces the new suction cup to the working position. After the model change is completed, the AGV cart drives away from the change model position, solving the problem of low compatibility of the fixed change model table. The use of a mobile change model table has stronger compatibility and higher model change efficiency, thereby improving space utilization. Description of the Drawings
