[0002] As an important part of modern energy storage system, the production efficiency and product quality of energy storage PACK are directly related to the reliability and economic benefits of the entire energy system. At present, the production process of energy storage PACK is roughly as follows: first, the bottom shell is subjected to air tightness detection to ensure that the sealing performance of the bottom shell meets the standard, preventing the internal battery module from being affected by moisture or pollution. Then, the battery module and the cover are sequentially assembled on the bottom shell to form a complete PACK package. Finally, the quality of the assembled PACK package is detected to ensure that it meets the relevant standards and customer requirements.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0052] The utility model provides a kind of energy storage PACK automatic assembly machine, for solve how to improve production efficiency Problem.

[0053] Referring to Figure 1 As shown, Figure 1 It is the perspective drawing of the energy storage PACK automatic assembly machine in the embodiment, and the energy storage PACK automatic assembly machine includes bottom shell feed line 1, assembly production line 2 and test production line 3 connected in sequence.

[0054] Bottom shell feed line 1 is used to place and transport bottom shell 41. Bottom shell airtightness detection device 11 is installed on bottom shell feed line 1. Bottom shell airtightness detection device 11 is used to detect the airtightness of bottom shell 41.

[0055] Assembly production line 2 is used to receive bottom shell 41 output by bottom shell feed line 1, and place and assemble battery module 42 and cover 43 on bottom shell 41 in sequence to form PACK bag 4.

[0056] Test production line 3 is used to receive PACK bag 4 output by assembly production line 2. PACK airtightness detection station 31 and EOL detection station 32 are sequentially arranged on test production line 3. PACK airtightness detection device 33 is installed on one side of PACK airtightness detection station 31, and PACK airtightness detection device 33 is used to test the airtightness of PACK bag 4 in PACK airtightness detection station 31. EOL detection device 34 is installed on one side of EOL detection station 32, and EOL detection device 34 is used to test the EOL of PACK bag 4 in EOL detection station 32.

[0057] The energy storage PACK automatic assembling machine works as follows: firstly, the bottom shell feeding line 1 delivers the bottom shell 41 to the bottom shell air tightness detection device 11 for air tightness detection, and then the bottom shell feeding line 1 inputs the bottom shell 41 to the assembling production line 2; then, the battery module 42 and the cover body 43 are placed and assembled on the bottom shell 41 by manual or mechanical equipment to form the PACK package 4; then, the assembling production line 2 inputs the PACK package 4 to the testing production line 3, and the testing production line 3 delivers the PACK package 4 to the PACK air tightness detection station 31 and the EOL detection station 32 in sequence, the PACK air tightness detection device 33 performs air tightness test on the PACK package 4 when the PACK package 4 is delivered to the PACK air tightness detection station 31, and the EOL detection device 34 performs EOL test on the PACK package 4 when the PACK package 4 is delivered to the EOL detection station 32. It can be seen that the bottom shell feeding line 1, the assembling production line 2 and the testing production line 3 are combined to connect the assembling and quality detection links of the energy storage PACK, and a coherent and efficient production assembly line is formed, compared with the prior art, the number of material handling between different processes is effectively reduced, the production interruption and time waste caused by handling are avoided, and the overall production efficiency is improved. Moreover, the energy storage PACK automatic assembling machine performs comprehensive quality detection on the PACK package 4 through the bottom shell air tightness detection device 11, the PACK air tightness detection device 33 and the EOL detection device 34, and the quality of the PACK package 4 is effectively ensured.

[0058] The bottom shell feeding line 1, the assembling production line 2 and the testing production line 3 can each independently install a set of existing belt conveying mechanism or drum conveying mechanism for conveying workpieces, and the three sets of conveying mechanisms are combined to form a coherent conveying line. The bottom shell feeding line 1, the assembling production line 2 and the testing production line 3 can also use the same set of existing belt conveying mechanism or drum conveying mechanism to form a coherent conveying line.

[0059] Referring to Figure 2 and Figure 3 , Figure 2 is a structure schematic view of the PACK air tightness detection station of the testing production line in the embodiment, Figure 3Figure 2 shows a schematic diagram of a partial structure of the PACK leak detection device in the embodiment. In one embodiment of the PACK leak detection device 33, the PACK leak detection device 33 comprises a leak tester 331 and a first driving mechanism 332. The leak tester 331 is located at one side of the PACK leak detection station 31 and comprises a gas pipe joint 3311. The first driving mechanism 332 is arranged on the test production line 3 by screwing or welding and is in transmission connection with the gas pipe joint 3311. The first driving mechanism 332 is used to drive the gas pipe joint 3311 to move relative to the PACK package 4 of the PACK leak detection station 31. In this way, when the PACK package 4 on the test production line 3 is conveyed to the PACK leak detection station 31, first, the first driving mechanism 332 drives the gas pipe joint 3311 to move relative to the PACK package 4 so that the gas pipe joint 3311 is opposite the deflation valve of the PACK package 4; then, the first driving mechanism 332 drives the gas pipe joint 3311 to be inserted into the deflation valve; finally, the leak tester is started to test the PACK package 4 for leak, and after the test is completed, the first driving mechanism 332 drives the gas pipe joint 3311 to be pulled out of the deflation valve and return to the original position. It can be seen that the test production line 3 can automatically test the PACK package 4 of different models for leak by the PACK leak detection device 33, and the application range is wide.

[0060] The above-mentioned leak tester 331 can use an existing leak tester 331, and the leak tester 331 of model JZCY020 is used in the embodiment. The above-mentioned first driving mechanism 332 can use an existing two-axis moving mechanism, which can drive the gas pipe joint 3311 to move vertically and horizontally to adjust the position of the gas pipe joint 3311 opposite the deflation valve of the PACK package 4 and can also drive the gas pipe joint 3311 to be inserted into or pulled out of the deflation valve.

[0061] Referring to Figures 3 and 4, Figure 4 and Figure 5 , Figure 4 Figure 3 shows a schematic diagram of a structure of the EOL detection station of the test production line in the embodiment, Figure 5FIG. 2 is a schematic view of a partial structure of the EOL detection device in the embodiment. In one embodiment of the EOL detection device 34, the EOL detection device 34 comprises an EOL tester 341 and a second driving mechanism 342. The EOL tester 341 is located at one side of the EOL detection station 32 and comprises a first plug 3411 and a second plug 3412. The second driving mechanism 342 is arranged on the test production line 3 by screwing or welding, etc., and is in driving connection with the first plug 3411 and the second plug 3412. The second driving mechanism 342 is used to drive the first plug 3411 and the second plug 3412 to move relative to the PACK package 4 of the EOL detection station 32. In this way, when the PACK package 4 on the test production line 3 is conveyed to the EOL detection station 32, first, the second driving mechanism 342 drives the first plug 3411 and the second plug 3412 to move relative to the PACK package 4, so that the first plug 3411 and the second plug 3412 are opposite to the corresponding socket positions on the PACK package 4; then, the driving mechanism drives the first plug 3411 and the second plug 3412 to be inserted into the corresponding sockets; finally, the EOL tester 341 is started to perform EOL test on the PACK package 4, and after the test is completed, the driving mechanism drives the first plug 3411 and the second plug 3412 to be pulled out of the corresponding sockets and return to the original position. It can be seen that the test production line 3 can automatically perform EOL test on PACK packages 4 of different models through the EOL detection device 34, and has wide application range.

[0062] The above-mentioned EOL tester 341 can use existing EOL related test equipment such as a safety regulation comprehensive analyzer, and the safety regulation comprehensive analyzer of model SE7430 is used in the embodiment. The above-mentioned second driving mechanism 342 can use existing two-axis moving mechanism, which can drive the first plug 3411 and the second plug 3412 to move together in vertical and horizontal directions, so as to adjust the positions of the first plug 3411 and the second plug 3412 to be opposite to the corresponding socket positions on the PACK package 4, and can also drive the first plug 3411 and the second plug 3412 to be synchronously inserted into or pulled out of the corresponding sockets.

[0063] Referring to Figure 5As shown, on the basis of the above embodiment, the EOL detection device 34 further comprises a third driving mechanism 343. The third driving mechanism 343 is arranged on the output end of the second driving mechanism 342 by screwing or welding, etc., and the output end of the third driving mechanism 343 is connected with the second plug 3412. The third driving mechanism 343 is used to drive the second plug 3412 to move relative to the PACK package 4 of the EOL detection station 32. Thus, since the length of the second plug 3412 is smaller than the length of the first plug 3411, the first plug 3411 may be inserted into the first socket, but the second plug 3412 is not inserted into the second socket, in order to solve this problem, the EOL detection device 34 can drive the second plug 3412 to be inserted into the second socket by the third driving mechanism 343, so as not to affect the normal operation of the EOL test.

[0064] The above third driving mechanism 343 can use existing telescopic air cylinders or telescopic electric poles, etc.

[0065] Referring to Figure 1 As shown, in an embodiment of the assembly production line 2, the assembly production line 2 is sequentially provided with a glue coating station 21, a module feeding station 22, a cover body feeding station 23 and an assembly station 24. The glue coating station 21 is provided with a glue coating device 25 on one side, and the glue coating device 25 is used to coat the heat-conducting glue for the bottom shell 41 of the glue coating station 21. The assembly station 24 is provided with a tightening device 26 on one side, and the tightening device 26 is used to screw the cover body 43 and the bottom shell 41. Thus, after the bottom shell feeding line 1 inputs the bottom shell 41 into the assembly production line 2, the assembly production line 2 first transports the bottom shell 41 to the glue coating station 21, and the glue coating device 25 coats the heat-conducting glue for the bottom shell 41; then the assembly production line 2 transports the bottom shell 41 to the module feeding station 22, and places the battery module 42 on the bottom shell 41 at a predetermined position by manual or mechanical equipment; then, the assembly production line 2 transports the assembly of the bottom shell 41 and the battery module 42 to the cover body feeding station 23, and places the cover body 43 on the bottom shell 41 at a predetermined position by manual or mechanical equipment; finally, the assembly production line 2 transports the assembly to the assembly station 24, and fixes the cover body 43 and the bottom shell 41 by screwing or other fasteners by the tightening device 26, so as to form a complete PACK package 4. It can be seen that the assembly production line 2 can semi-automatically or automatically assemble the PACK package 4, and the heat-conducting performance between the battery module 42 and the bottom shell 41 can be enhanced by coating the heat-conducting glue between the battery module 42 and the bottom shell 41 during the assembly process, so as to improve the performance of the PACK package 4.

[0066] The above glue coating device 25 can use existing glue coating equipment such as Kehua glue filling line, etc.

[0067] Referring to Figure 6 As shown, Figure 6As shown in the structural schematic diagram of the assembly station of the assembly line in the embodiment, in an embodiment of the tightening device 26, the tightening device 26 comprises a tightening mechanism 261, a position adjusting mechanism 262 and a visual detection mechanism 263. The position adjusting mechanism 262 is arranged on the assembly line 2 by screwing or welding, etc., and the output end of the position adjusting mechanism 262 is connected with the tightening mechanism 261 and the visual detection mechanism 263 by screwing or welding, etc. The visual detection mechanism 263 is used to detect the position to be screwed of the cover 43 and the bottom shell 41; the position adjusting mechanism 262 is used to drive the tightening mechanism 261 and the visual detection mechanism 263 to move relative to the workpiece of the assembly station 24, so as to move the tightening mechanism 261 to the position to be screwed of the cover 43 and the bottom shell 41; and the tightening mechanism 261 is used to screw the cover 43 and the bottom shell 41. In this way, when the assembly line 2 delivers the workpiece to the assembly station 24, the position adjusting mechanism 262 drives the tightening mechanism 261 and the visual detection mechanism 263 to move relative to the workpiece, and in the process of movement, the visual detection mechanism 263 detects the position to be screwed of the workpiece in real time, so as to drive the tightening mechanism 261 to be opposite to the position to be screwed by the position adjusting mechanism 262; then, the tightening mechanism 261 screws the fastener such as bolt or screw at the position to be screwed, and after the screwing is completed, the position adjusting mechanism 262 drives the tightening mechanism 261 and the visual detection mechanism 263 to move relative to the workpiece again, and the above steps are repeated to screw the positions to be screwed of the workpiece in sequence. It can be seen that the assembly line 2 can automatically screw the positions to be screwed of the cover 43 and the bottom shell 41, and effectively improves the production efficiency.

[0068] The tightening mechanism 261 can use the existing side blowing and sucking tightening module, can suck the fastener such as bolt or screw, and screw the fastener at the position to be screwed of the cover 43 and the bottom shell 41, so as to realize the screwing of the cover 43 and the bottom shell 41. The position adjusting mechanism 262 can use the existing two-axis moving mechanism, can drive the tightening mechanism 261 to move in the horizontal direction and the vertical direction, so as to switch the tightening mechanism 261 to be opposite to different positions to be screwed. The visual detection mechanism 263 can use the existing CCD camera, can accurately collect the position information of the position to be screwed by vision.

[0069] Reference is made to Figure 1As shown, on the basis of the above-mentioned bottom shell feeding line 1 embodiment, the bottom shell feeding line 1 is provided with a feeding station 12. One side of the feeding station 12 is provided with a bottom shell feeding device 13, a storage rack 14 and an empty rack 15. The storage rack 14 and the empty rack 15 are both used for stacking and placing the trays 16. The tray 16 has a plurality of troughs 161 for accommodating and limiting the bottom shells 41. The bottom shell feeding device 13 is located upstream of the bottom shell airtightness detection device 11 and is used for carrying the bottom shells 41 on the uppermost layer of the storage rack 14 to the feeding station 12 one by one, and carrying and stacking the empty uppermost layer of the storage rack 14 to the empty rack 15. In this way, the energy storage PACK automatic assembly machine not only can automatically feed the bottom shells 41 on the storage rack 14 through the bottom shell feeding device 13, but also can automatically stack the empty trays 16 on the empty rack 15, and the function is flexible and diverse; wherein the storage rack 14 can store a large number of bottom shells 41 through the tray 16 for feeding, and can also avoid accidental damage to the bottom shells 41 during storage.

[0070] Referring to Figure 1 and Figure 7 as shown, Figure 7For the perspective view of the feeding clamp in the embodiment, in one embodiment of the bottom shell feeding device 13, the bottom shell feeding device 13 comprises a feeding clamp 131, a feeding manipulator 132 and a feeding visual detection member 133. The feeding clamp 131 comprises a first frame body 1311, a rotary driving member 1312, a swing arm 1313, two connecting rods 1314 and two feeding clamp arms 1315. The rotary driving member 1312 is arranged on the first frame body 1311 by screwing or welding, etc. The output end of the rotary driving member 1312 is connected with the middle part of the swing arm 1313 by screwing or welding, etc. The two ends of the swing arm 1313 are rotatably connected with one end of the two connecting rods 1314. The other end of the connecting rod is rotatably connected with the feeding clamp arm 1315. The feeding clamp arm 1315 is slidably connected with the first frame body 1311. The rotary driving member 1312 is used to drive the swing arm 1313 to rotate. The swing arm 1313 drives the two feeding clamp arms 1315 to move close to or away from each other through the connecting rods, so as to clamp or release the two sides of the bottom shell 41 or the tray 16. The feeding manipulator 132 is located on one side of the bottom shell feeding line 1 and is drivingly connected with the first frame body 1311. The feeding manipulator 132 is used to drive the feeding clamp 131 to move between the bottom shell feeding line 1, the storage rack 14 and the empty rack 15. The feeding visual detection member 133 is fixedly arranged on the first frame body 1311 by screwing or welding, etc. and is used to detect whether the bottom shell 41 is placed in the trough 161. In this way, when the bottom shell 41 is fed, firstly, the feeding manipulator 132 drives the feeding clamp 131 to move to the storage rack 14. During the moving process, the feeding visual detection member 133 detects in real time whether the bottom shell 41 is placed in the trough 161 of the uppermost tray 16 of the storage rack 14, so as to collect the position of the bottom shell 41 to be grabbed. Then, according to the collected position of the bottom shell 41 to be grabbed, the feeding manipulator 132 and the feeding clamp 131 cooperate to grab the bottom shell 41 and move to the feeding station 12, so as to realize the feeding of the bottom shell 41. Next, the feeding manipulator 132 drives the feeding clamp 131 to move to the storage rack 14 again. The above-mentioned feeding operation of the bottom shell 41 is repeatedly performed until the feeding visual detection member 133 detects that there is no bottom shell 41 in all the troughs 161 of the uppermost tray 16 of the storage rack 14. Then, the feeding manipulator 132 and the feeding clamp 131 cooperate to grab the uppermost tray 16 and move to the empty rack 15, so as to be stacked on other empty trays 16 of the empty rack 15, thereby realizing the stacking of the empty tray 16. The above-mentioned process is repeatedly performed until all the trays 16 of the storage rack 14 are moved to the empty rack 15. Then, a stack of trays 16 with the bottom shell 41 is supplemented to the storage rack 14 by manual or mechanical equipment. It can be seen that the bottom shell feeding device 13 can not only grab the bottom shell 41 but also grab the tray 16 through the feeding clamp 131, so the adaptability is high.
