However, this way has obvious functional limitation, that is, can only complete the carrying and boxing task of the battery module, lacks the integration of other necessary processes. For example, before the offline of the battery module into the box, the trolley lower shell is usually installed into the bottom shell box as the supporting and fixing structure of the battery module. However, the existing module offline equipment does not contain this step, resulting in the need for manual installation of the trolley lower shell, reducing the degree of automation and efficiency of the production line. In addition, the surface of the battery module may be contaminated by dust, oil stains and other pollutants during production or conveying. If these pollutants are not cleaned in time, not only the appearance of the battery module will be affected, but also the performance and safety of the battery module may be negatively affected. However, the existing module offline equipment generally lacks the cleaning process of the battery module, so that the battery module cannot be effectively cleaned before boxing, thereby increasing the product quality risk and safety hazard.

[0004] In view of the above problems, it is particularly important to develop a module automatic offline equipment integrating the carrying of the battery module, the automatic installation of the trolley lower shell and the cleaning of the battery module. INVENTION CONTENTS

[0052] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0053] The utility model provides a kind of module automatic offline equipment, battery module handling, trolley lower shell automatic installation and battery module cleaning are integrated in one, can effectively improve product quality.

[0054] Referring to Figure 1 As shown in the figure, Figure 1 It is the perspective view of the module automatic offline equipment in the embodiment, and the module automatic offline equipment includes rack 1, feed conveying line 2, plasma cleaning device 3, transfer device 4 and transfer device 5.

[0055] Rack 1 is provided with module feeding station 11, lower shell feeding station 12 and boxing station 13.

[0056] Feed conveying line 2 is installed on rack 1, and is used to convey battery module.

[0057] Plasma cleaning device 3 is installed on rack 1, and is located downstream of feed conveying line 2. Plasma cleaning device 3 is used to clean the surface of battery module by plasma.

[0058] Transfer device 4 is located at module feeding station 11, and is located downstream of plasma cleaning device 3. Transfer device 4 is used to store surface clean battery module.

[0059] The transfer device 5 is mounted on the frame 1. The transfer device 5 is used to load the lower shell of the trolley at the lower shell loading station 12 into the bottom shell box at the boxing station 13, and to assemble the cell molds at the module loading station 11 onto the lower shell of the trolley at the boxing station 13.

[0060] When using the automatic module unloading equipment of the above technical solution, firstly, battery cell modules are continuously input through the feeding conveyor line 2. If the surface of the battery cell module is contaminated, the contaminated battery cell module is manually or mechanically transferred to the plasma cleaning device 3 for plasma cleaning. Then, the battery cell modules that do not need cleaning on the feeding conveyor line 2 and the cleaned battery cell modules on the plasma cleaning device 3 are manually or mechanically moved to the transfer device 4 for storage. Finally, the transfer device 5 loads the lower shell from the loading station 12. The lower housing of the trolley is loaded into the bottom box of the packing station 13. Then, the battery cell modules from the module loading station 11 are loaded one by one onto the lower housing of the trolley at the packing station 13. After the lower housing of the trolley is full, the transfer device 5 loads the next lower housing of the trolley from the lower housing loading station 12 back into the bottom box, stacking it on top of the previously filled lower housing. The battery cell modules from the module loading station 11 are then loaded one by one onto the lower housing of the trolley at the packing station 13, and this process is repeated until the bottom box is full. It can be seen that this automatic module unloading equipment integrates battery cell module handling, automatic installation of the lower housing of the trolley, and cleaning of the battery cell modules. It can clean the surface contaminants of the battery cell modules in a timely manner before packing, thereby effectively improving product quality.

[0061] The aforementioned feeding conveyor line 2 can use existing conveying mechanisms such as belt conveyors or roller conveyors.

[0062] A vision transfer device can also be installed between the feeding conveyor line 2 and the plasma cleaning device 3 of the aforementioned automatic module unloading equipment. This vision transfer device can be composed of an existing CCD camera, a cell module clamp, and a robotic arm. In this way, the vision transfer device can visually inspect the surface quality of the cell modules on the feeding conveyor line 2 using the CCD camera. Based on the inspection results, the vision transfer device can also transfer unqualified cell modules from the feeding conveyor line 2 to the plasma cleaning device 3 for plasma cleaning, using the cell module clamp and the robotic arm. Qualified cell modules from the feeding conveyor line 2 and cleaned cell modules from the plasma cleaning device 3 are moved to the transfer device 4 for storage. This effectively improves the automation level and production efficiency of the automatic module unloading equipment, thereby further improving product quality.

[0063] See Figure 2 and Figure 3 As shown, Figure 2 for Figure 1 Enlarged diagram of point A in the middle. Figure 3FIG. 1 is a perspective view of the plasma cleaning device in an embodiment. In one embodiment of the plasma cleaning device 3, the plasma cleaning device 3 comprises a turntable 31, a nozzle 32, and a position adjusting mechanism 33. The turntable 31 is installed on the frame 1. The turntable 31 is provided with at least two jigs 311 arranged in a ring shape and spaced apart. The jigs 311 are used to place and position the battery module. The turntable 31 is provided with a corresponding passageway 312 for each jig 311. The nozzle 32 is located below the turntable 31 and opposite to one of the jigs 311. The nozzle 32 is used to emit plasma. The position adjusting mechanism 33 is installed on the frame 1 by screwing or welding, and is in transmission connection with the nozzle 32 by screwing or welding. The position adjusting mechanism 33 is used to drive the nozzle 32 to move relative to the corresponding jig 311. In this way, during cleaning, the turntable 31 rotates, so that each jig 311 is in turn opposite to the nozzle 32. When any jig 311 is opposite to the nozzle 32, the position adjusting mechanism 33 drives the nozzle 32 to move relative to the jig 311 and the battery module thereon, so that the nozzle 32 is aligned with the corresponding passageway 312, and the cleaning position and range of the nozzle 32 on the surface of the battery module are adjusted. After adjustment, the nozzle 32 emits plasma through the passageway 312 to clean the surface of the battery module. During the cleaning process, the position adjusting mechanism 33 can continue to drive the nozzle 32 to move relative to the jig 311, so that the nozzle 32 can clean the surface of the battery module.

[0064] The above-mentioned turntable 31 can use an existing index plate. The above-mentioned nozzle 32 can be connected with an existing plasma generating device, so that the nozzle 32 can emit plasma to clean the surface of the battery module. The above-mentioned position adjusting mechanism 33 can use an existing three-axis moving mechanism, which can drive the nozzle 32 to move in three dimensions, i.e., in the horizontal direction, the vertical direction, and the longitudinal direction, so as to adjust the three-dimensional position of the nozzle 32.

[0065] Referring to Figure 3 The plasma cleaning device 3 further comprises a lifting mechanism 34 based on the above-mentioned embodiment. The lifting mechanism 34 is installed on the frame 1 by screwing or welding, and is opposite to one of the jigs 311. The lifting mechanism 34 is used to drive the battery module on the corresponding jig 311 to move up and down. In this way, the output end of the lifting mechanism 34 can lift the battery module away from the corresponding jig 311 through the passageway 312, so that the battery module can be handled by manual or mechanical equipment. After handling, the output end of the lifting mechanism 34 can return to the original position, so that the battery module can be placed back on the corresponding jig 311, and the turntable 31 can rotate to transfer the battery module.

[0066] The above-mentioned lifting mechanism 34 can use an existing telescopic pneumatic cylinder or a ball screw linear module.

[0067] Referring toFigure 4 As shown in Figure 4 As shown in FIG. 4, in an embodiment of the transfer device, the transfer device 4 comprises a transfer trolley 41 and a positioning mechanism 42. The transfer trolley 41 has a plurality of transfer stations 411 for placing the surface-cleaned battery cell modules. The positioning mechanism 42 is installed at the module loading station 11 of the rack 1, and is used to fix the transfer trolley 41 at the module loading station 11. In this way, a plurality of surface-cleaned battery cell modules can be stored in the transfer trolley 41, which not only facilitates the transfer device 5 to grasp and carry the battery cell modules for packaging, but also facilitates the staff to transport the surface-cleaned battery cell modules to the warehouse and the like. The positioning mechanism 42 can fix the transfer trolley 41 at the module loading station 11, so as to avoid the transfer trolley 41 from moving during the process that the transfer device 5 grasps the battery cell modules for packaging, thereby affecting the grasping and packaging operation of the transfer device 5.

[0068] As shown in Figure 4 and Figure 5 As shown in Figure 5 As shown in FIG. 5, in an embodiment of the positioning mechanism, the positioning mechanism 42 comprises a first clamping plate 421, a second clamping plate 422 and a driving member 423. The first clamping plate 421 and the driving member 423 are fixed on the rack 1 by screwing or welding, and the output end of the driving member 423 is connected with the second clamping plate 422 by screwing or welding. The driving member 423 is used to drive the second clamping plate 422 to flip towards or away from the first clamping plate 421, so as to clamp or release the transfer trolley 41. In this way, the positioning mechanism 42 can control the positioning of the transfer trolley 41 by driving the second clamping plate 422 to flip relative to the first clamping plate 421 through the driving member 423. This way of controlling the positioning is simple and easy to implement.

[0069] The above-mentioned driving member 423 can use an existing flip cylinder or a flip driving mechanism such as a motor.

[0070] As shown in Figure 4 and Figure 5 On the basis of the above-mentioned embodiment of the transfer trolley 41, the transfer trolley 41 comprises a guide pulley 412, and the rack 1 comprises a guide rail 14. The guide rail 14 is used to be in sliding connection with the guide pulley 412, so as to guide the transfer trolley 41 to move towards the module loading station 11. In this way, the guide pulley 412 and the guide rail 14 can be used to quickly guide the transfer trolley 41 to move into position, thereby improving the production efficiency of the module automatic offline device.

[0071] As shown in Figure 1 and Figure 6 As shown in Figure 6For the perspective view of the clamp in the embodiment, in one embodiment of the transfer device 5, the transfer device 5 comprises a mechanical hand 51 and a clamp 52. The clamp 52 is used to clamp or release the trolley lower shell or the battery cell module. The mechanical hand 51 is arranged on the rack 1 by screwing or welding, etc., and is in transmission connection with the clamp 52. The mechanical hand 51 is used to drive the clamp 52 to move between the module feeding station 11, the lower shell feeding station 12 and the boxing station 13, so as to load the trolley lower shell at the lower shell feeding station 12 into the bottom shell box at the boxing station 13, and load the battery cell module at the module feeding station 11 onto the trolley lower shell at the boxing station 13. In this way, the transfer device 5 cooperates with the mechanical hand 51 and the clamp 52, which can not only grab the in-box trolley lower shell, but also grab the in-box battery cell module, and has high applicability.

[0072] The above-mentioned mechanical hand 51 can use the existing mechanical hand 51 equipment.

[0073] Referring to Figure 6 As shown in the figure, in one embodiment of the clamp 52, the clamp 52 comprises a mounting seat 521, a first clamping arm 522, a first clamping arm driving member 523, a second clamping arm 524 and a second clamping arm driving member 525. The first clamping arm 522 is arranged in two and is in sliding connection with the mounting seat 521. The first clamping arm driving member 523 is arranged on the mounting seat 521 by screwing or welding, etc., and the output end of the first clamping arm driving member 523 is connected with the two first clamping arms 522 by screwing or welding, etc. The first clamping arm driving member 523 is used to drive the two first clamping arms 522 to approach or move away from each other, so as to clamp or release the two sides of the length direction of the trolley lower shell or the battery cell module. The number of the second clamping arm 524 and the second clamping arm driving member 525 is two. The second clamping arm 524 is rotatably connected to the mounting seat 521 through a rotating shaft, and the second clamping arm driving member 525 is arranged on the mounting seat 521 by screwing or welding, etc. The output end of the second clamping arm driving member 525 is connected with the second clamping arm 524 by screwing or welding, etc. The two second clamping arm driving members 525 are combined to drive the two second clamping arms 524 to approach or move away from each other, so as to clamp or release the two sides of the width direction of the trolley lower shell or the battery cell module. In this way, the first clamping arm driving member 523 can adjust the distance between the two first clamping arms 522, so as to adapt to the length of the trolley lower shell or different battery cell modules, greatly improving the application range of the clamp 52; and the second clamping arm driving member 525 can adjust the relative angle of the two second clamping arms 524, so as to assist the first clamping arm 522 to clamp the trolley lower shell or the battery cell module.

[0074] The above-mentioned first clamping arm driving member 523 can use the existing linear displacement driving mechanism such as servo motor-bi-directional ball screw module, and the above-mentioned second clamping arm driving member 525 can use the existing rotary driving mechanism such as rotary motor-gear set or telescopic air cylinder-rack and pinion set.

In this way, the at least two side positioning mechanisms 62 cooperate to limit the position of the bottom shell box in the length direction, and the pressing plate 63 and the pressing plate driving mechanism 64 cooperate to limit the position of the bottom shell box in the height direction. In this way, the box positioning device 6 cooperates with the limiting frame 61, the side positioning mechanism 62, the pressing plate 63 and the pressing plate driving mechanism 64 to fix the three-dimensional position of the bottom shell box, so that the bottom shell box can be fixed firmly in the box loading station 13, and the situation that the bottom shell box moves in the loading process is effectively avoided; and the pressing plate driving mechanism 64 drives the pressing plate 63 to ascend to release the bottom shell box, and at the same time, the side positioning mechanism 62 opens any one end or both ends of the limiting passage 611, so that the bottom shell box can be conveniently moved out of the box loading station 13 along the limiting passage 611.

[0076] The above side positioning mechanism 62 can use an existing turnover clamping cylinder. The above pressing plate driving mechanism 64 can use an existing telescopic cylinder or a ball screw linear module or the like linear displacement driving mechanism.
