DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: an automatic variable-distance tightening device for a battery module, including a base 1, a vertical frame 2 is connected to the top surface of the base 1, an AGV cart 3 is placed on the top surface of the base 1 at one side of the vertical frame 2, a battery module 4 is connected to the top surface of the AGV cart 3, a servo slide table variable-distance device 5 is connected to the top surface of one vertical frame 2, the model of the servo slide table variable-distance device 5 is a TGH12 electric slide table, an assisting robot 6 is connected to the top surface of the movable block of the servo slide table variable-distance device 5, the model of the assisting robot 6 is an RX160 six-axis industrial robot, a mounting plate 7 is connected to the surface at one end of the assisting robot 6, a tightening gun 8 is arranged on one side surface at one end of the mounting plate 7, and an industrial CCD camera 9 is arranged on one side surface at the other end of the mounting plate 7. A convex block 10 is connected to the bottom surface of the mounting plate 7, a motor 11 is connected to one side surface of the convex block 10, the output end of the motor 11 extends into the convex block 10 and is connected to one end of a rotating shaft 12, one end of the rotating shaft 12 penetrates through a bearing 13 connected to the other side surface of the convex block 10, and one end of the rotating shaft 12 extends into a positioning groove 14, the positioning groove 14 is opened on one side surface of a baffle 15, a bolt 16 penetrates through the other side surface of the baffle 15, and one end of the bolt 16 extends into a fixing hole 17 opened on the surface of one end of the rotating shaft 12. A limiting mechanism is also arranged on one side surface of the mounting plate 7.

[0024] When the battery module 4 is processed, the AGV cart 3 will move the battery module 4 between the two vertical frames 2. The assisting robot 6 on the vertical frame 2 will drive the industrial CCD camera 9 to scan the PACK assembly code on the battery module 4, so that the tightening device will call the tightening program according to the code. At this time, the servo slide table variable-distance device 5 will automatically perform a variable-distance operation according to the set program, so that the servo slide table variable-distance device 5 can drive the assisting robot 6 to move at a fixed distance according to the set parameters. In this way, the assisting robot 6 will move to the position of the first screw in the preset order for the industrial CCD camera 9 to perform visual grasping, so that the assisting robot 6 can drive the tightening gun 8 to move to the screw position for tightening operation. After reaching the target torque and angle, the tightening data will be bound and uploaded to the MES together with information such as barcodes. In this way, moving and driving the tightening gun 8 to perform the tightening operation can complete the processing operation of this item of the battery module 4.

[0025] Preferably, the limiting mechanism includes: an electric push rod 18, a first slot 19, and a second slot 20. One side surface of the mounting plate 7 is connected with an electric push rod 18, and the movable end of the electric push rod 18 extends into the first slot 19. The first slot 19 is opened on one side surface of the baffle 15, and a second slot 20 is also opened on one side surface of the baffle 15.

[0026] During specific use, when the movable end of the electric push rod 18 slides and fits into the first slot 19 or the second slot 20, the position of the current baffle 15 will be restricted, avoiding the situation of the baffle 15 shaking during use.

[0027] Preferably, the motor 11 and the electric push rod 18 are electrically connected through a PLC control switch and an external power supply, and a fixed connection is formed between the output end of the motor 11 and the rotating shaft 12.

[0028] During specific use, the model of the PLC control switch is the S7-200 small PLC control switch, and the connected devices can be switched on and off through programming. The industrial CCD camera 9 is also connected to the PLC control switch. By programming the PLC control switch, the PLC control switch can control the motor 11 and the electric push rod 18 under set conditions. When the output end of the motor 11 rotates, it can drive the rotating shaft 12 to rotate.

[0029] Preferably, the rotating shaft 12 is slidably connected to the baffle 15 through a positioning slot 14, and the bolt 16 is threadedly connected to the fixing hole 17 through the baffle 15.

[0030] During specific use, one end of the rotating shaft 12 can slide and fit into the positioning slot 14 on the baffle 15. At this time, the bolt 16 is passed through the baffle 15 and screwed into the fixing hole 17, and the rotating shaft 12 can be connected to the baffle 15.

[0031] Preferably, the size and position of the baffle 15 match the size and position of the lens of the industrial CCD camera 9.

[0032] During specific use, after the baffle 15 rotates, it can just block in front of the lens of the industrial CCD camera 9, so that the baffle 15 can block the lens of the industrial CCD camera 9 and reduce the exposure time of the lens of the industrial CCD camera 9 in the environment.

[0033] Preferably, the movable end of the electric push rod 18 is slidably connected to the baffle 15 through the first slot 19 or the second slot 20.

[0034] During specific use, when the moving end of the electric push rod 18 moves, it can slide and fit into the first slot 19 or the second slot 20. When the moving end of the electric push rod 18 fits into the first slot 19, it indicates that the baffle 15 blocks the industrial CCD camera 9. When the moving end of the electric push rod 18 fits into the second slot 20, it indicates that the baffle 15 does not block the industrial CCD camera 9.

[0035] Working principle of implementation: When using this automatic variable pitch tightening device for battery modules, when the industrial CCD camera 9 on the tightening device does not perform visual grasping, the PLC control switch will start the motor 11, and the output end of the motor 11 will drive the rotating shaft 12 to rotate 180 degrees in the bearing 13. In this way, the rotating shaft 12 will drive the baffle 15 to rotate, so that the baffle 15 can rotate to the front end of the lens of the industrial CCD camera 9, and thus the baffle 15 will be blocked by the lens of the industrial CCD camera 9. At the same time, the PLC control switch will start the electric push rod 18, and the moving end of the electric push rod 18 will slide into the first slot 19, thereby restricting the position of the baffle 15. Such an operation can reduce the time for the lens of the industrial CCD camera 9 to be exposed to the environment, extend the time interval for cleaning dust or debris on the lens, and thus reduce the number of times the lens of the industrial CCD camera 9 needs to be cleaned within the same time, bringing convenience to the operator. When the industrial CCD camera 9 needs to be used, the PLC control switch will first start the electric push rod 18, and the moving end of the electric push rod 18 will move out of the first slot 19. At this time, the output end of the motor 11 will drive the rotating shaft 12 to rotate 180 degrees again, so that the baffle 15 rotates to the lower position. At this time, the moving end of the electric push rod 18 will move again, and the moving end of the electric push rod 18 will slide into the second slot 20, thereby restricting the position of the baffle 15 again. In this way, the baffle 15 will no longer block the industrial CCD camera 9, allowing the industrial CCD camera 9 to be used normally. The output end of the electric push rod 18 can limit the position of the baffle 15 by sliding into the first slot 19 or the second slot 20, avoiding the situation of the baffle 15 shaking during use.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
