The motor 2121 is a servo motor 2121, which is arranged on the seat body 211 and has an output end connected with the screw rod 2122. The screw rod 2122 is pivotally connected with the seat body 211 and has a pivot center axis parallel with the moving direction of the pressing block 214. The nut 2123 is threadedly connected with the screw rod 2122. The driving plate 2124 is movably arranged on the seat body 211 and connected with the nut 2123. One end of the push rod 2125 is connected with the driving plate 2124, and the other end is connected with the pressing plate 213 to drive the pressing plate 213 to move. The rotation of the motor 2121 is converted into linear translation by the screw rod 2122 and the nut 2123, so that the driving plate 2124 can be driven to move linearly, and the push rod 2125 can be driven. Moreover, the transmission of the screw rod 2122 and the nut 2123 is very accurate, so that the pressing block 214 can be accurately compressed together, which is beneficial to accurately control the moving distance of the pressing block 214 and the pressure between the two pressing blocks 214, and ensures the accurate and controllable pressure. In the embodiment, the number of the screw rod 2122 and the nut 2123 is two, which are used to jointly drive the same driving plate 2124. In this way, the linear motion of the two ends of the driving plate 2124 can be synchronized and accurate, and the stability and accuracy of the transmission are improved.
[0066] For example Figure 8 As shown, the driving mechanism 212 further includes a transmission mechanism 2126, which includes a driving gear 2126a, two driven gears 2126b and two intermediate gears 2126c. The driving gear 2126a is connected with the output end of the motor 2121. The two driven gears 2126b are respectively connected with one end of the two screw rods 2122. The two intermediate gears 2126c are respectively arranged between the driving gear 2126a and the driven gears 2126b and respectively engaged with the two. The transmission mechanism 2126 can synchronously drive the two screw rods 2122, improve the stability of the transmission, and reduce the output speed of the motor 2121 to meet the clamping requirements of the pressing block 214.
[0067] Please refer to Figure 5 and Figure 6 The seat body 211 is provided with a box body 2113, and the screw rod 2122, the nut 2123 and the driving plate 2124 are arranged in the box body 2113. The box body 2113 can protect the important components such as the screw rod 2122, the nut 2123 and the driving plate 2124, prevent foreign matters from entering the inside to affect the transmission effect, and ensure the stability of the transmission.
[0068] For example Figure 5 and Figure 7 As shown, in this embodiment, the linkage 215 is a rigid component with an elongated hole 2151. The pressure block 214 has a pin 2142, and the pins 2142 of two adjacent pressure blocks 214 are slidably inserted into the elongated hole 2151 of the same rigid component located between them. This allows adjacent pressure blocks 214 to press against or pull apart by a certain distance, facilitating the clamping or loosening of the soft-pack battery and enabling repeated cyclical operation for continuous work. Specifically, the upper side of the pressure block 214 has a groove 2143, and the rigid component and the pin 2142 are disposed within the groove 2143. The groove 2143 makes the structure more compact and rational. Of course, the linkage 215 can also be a flexible connector, such as a rope or wire.
[0069] Please see Figures 9 to 12The piercing device 22 comprises a bracket 221, a first sliding plate 222, a first cylinder 223, a connecting block 224, a first clamping block 225, a second clamping block 226, a pair of springs 227, a pair of conductive bayonets 228 and a tab clamping mechanism 229. The first sliding plate 222 is slidingly arranged on the upper surface of the bracket 221. The first cylinder 223 is arranged on the upper surface of the bracket 221 and the output end is connected to the first sliding plate 222. The second clamping block 226 is arranged on the bracket 221. The connecting block 224 is fixedly arranged on the first sliding plate 222.

The connecting block 224 is slidingly sleeved on the guide column 2251. The guide column 2241 is arranged to make the connection of the first clamping block 225 relative to the connecting block 224 more stable. The spring 227 is arranged between the connecting block 224 and the first clamping block 225 and is sleeved outside the guide column 2241. The first clamping block 225 is provided with two through holes 2251. The conductive bayonet 228 is arranged on the connecting block 224. The conductive bayonet 228 is electrically connected with the test circuit of the tab clamping mechanism 229. The conductive bayonet 228 penetrates through the through hole 2251 when the first clamping block 225 and the second clamping block 226 are clamped, thereby piercing the soft-pack battery. The tab clamping mechanism 229 is located below the bracket 221. The tab clamping mechanism 229 clamps the positive and negative electrodes of the soft-pack battery and makes them electrically connected with the test circuit. By arranging the spring 227 and the conductive bayonet 228 between the first clamping block 225 and the connecting block 224 and driving the first clamping block 225 and the second clamping block 226 by the first cylinder 223, the conductive bayonet 228 can penetrate through the gap between the first clamping block 225 and the second clamping block 226, thereby piercing the soft-pack battery. The conductivity of the conductive bayonet 228 can directly test the pierced soft-pack battery. The conductive bayonet 228 serves as both a piercing tool and a testing tool, effectively simplifying the structure of the equipment and saving operation steps and improving testing efficiency. The piercing device 22 further comprises a second sliding plate 2210 and a second cylinder 2211. The second sliding plate 2210 is slidingly arranged on the lower bottom surface of the bracket 221. The second cylinder 2211 is arranged on the lower bottom surface of the bracket 221 and the output end is connected to the second sliding plate 2210. The second clamping block 226 is connected to the second sliding plate 2210. The second clamping block 226 is driven by the second sliding plate 2210 and the second cylinder 2211, so that the clamping effect of the first clamping block 225 and the second clamping block 226 is better and the piercing effect is better.
[0070] Please refer to Figure 12The second clamp block 226 is provided with a corresponding avoiding slot 2261 for the conductive bayonet 228. As the conductive bayonet 228 passes through the first clamp block 225 and approaches the second clamp block 226, the avoiding slot 2261 allows the conductive bayonet 228 to enter the second clamp block 226, so that the conductive bayonet 228 can fully pierce the soft-pack battery, thereby ensuring that the test conditions are effective.
[0071] Please refer to Figure 13 The tab clamping mechanism 229 includes a mounting bracket 2291, a horizontal movement driving cylinder 2292, a plurality of double-output clamping cylinders 2293, a plurality of pairs of clamping blocks 2294, and a plurality of conductive terminals 2295. The output end of the horizontal movement driving cylinder 2292 is connected with the mounting bracket 2291. The double-output clamping cylinders 2293 are arranged on the mounting bracket 2291 and the two output ends thereof are respectively connected with the clamping blocks 2294. The conductive terminals 2295 are respectively arranged on the clamping blocks 2294 to correspond to the positive and negative electrodes of the soft-pack battery. The tab clamping mechanism 229 also has a test circuit, and the conductive terminals 2295 are electrically connected with the test circuit of the tab clamping mechanism 229. By arranging the tab clamping mechanism 229, it can cooperate with the bayonet. When the bayonet pierces and contacts the aluminum plastic film of the soft-pack battery, an electric circuit loop is formed among the tab of the soft-pack battery, the conductive terminal 2295, the bayonet, and the aluminum plastic film of the battery, thereby realizing the short-circuit test of the soft-pack battery.
[0072] Please refer to Figures 14 to 16The positioning device 1 comprises a base 11, a first clamping jaw 12, a second clamping jaw 13, a first push plate 14, a second push plate 15, a first driving cylinder 16 and a second driving cylinder 17.

[0073] Please also refer to Figure 16 The first push plate 14 and the second push plate 15 are located at the lower part of the front side of the clamping groove 18, so that the tab of the soft-pack battery extends out of the front side of the clamping groove 18 and is located above the first push plate 14. In this way, the first push plate 14 and the second push plate 15 do not affect the tab, and the structure is more compact and reasonable.
[0074] Please also refer to Figure 16 The first driving cylinder 16 and the second driving cylinder 17 are located in the gap 19 between two adjacent clamping grooves 18. In this way, the remaining space on the base 11 can be fully utilized, so that the structure of the positioning device 1 is more compact and reasonable, and the volume is smaller.
[0075] Please also refer to Figure 14 and Figure 15 The upper side of the first clamping jaw 12 and the second clamping jaw 13 is provided with a plurality of clamping fingers, and the adjacent two clamping fingers are arranged in a gap. The clamping fingers are arranged to facilitate the clamping fingers of the first transfer and carrying mechanical hand 3 to pass through the gap between the adjacent two clamping fingers, so as to achieve the purpose of grabbing the soft-pack battery between the first clamping jaw 12 and the second clamping jaw 13, and improve the convenience of grabbing.
[0076] Please refer to Figure 14 , the positioning device 1 further comprises a translation driving device 20, which drives the base 11 to translate. By arranging the translation driving device 20, the positioning device 1 can transfer the soft-pack battery to the next work station while positioning the soft-pack battery, thereby shortening the production time and improving the work efficiency. The translation driving device 20 comprises a driving motor 201, a driving pulley 202, a driven pulley 203 and a belt 204. The driving pulley 202 is connected with the output end of the driving motor 201. The belt 204 is arranged between the driving pulley 202 and the driven pulley 203. The base 11 is arranged on the belt 204 and moves with the running of the belt 204. Specifically, the number of the driving pulley 202, the driven pulley 203 and the belt 204 is two sets, which are symmetrically arranged at the two ends of the base 11 respectively. The two driving pulleys 202 are connected with a linkage shaft 205. In this way, the two ends of the base 11 are subjected to the traction force of the translation driving device 20, so that the traction force is balanced and the base 11 moves more stably.
[0077] Please refer to Figures 17 to 21The code scanning device 5 includes a machine table 51, a platform 52, a clamp 53, a sliding plate 54, a translation cylinder 55, a plurality of code scanning cylinders 56, and a plurality of code scanners 57. The platform 52 is arranged on the machine table 51, the clamp 53 is arranged on the platform 52, and the clamp 53 has a plurality of positioning clamping jaws 531 for positioning the soft-pack battery. The sliding plate 54 is arranged on the machine table 51 in a sliding manner. Specifically, the machine table 51 is provided with a sliding rail 511, and the lower side of the sliding plate 54 is provided with a sliding block 541 that is in sliding cooperation with the sliding rail 511. The translation cylinder 55 is arranged on the machine table 51 and drives the sliding plate 54 to move along the arrangement direction of the positioning clamping jaws 531. The code scanning cylinders 56 are arranged on the sliding plate 54, and the output ends thereof are connected with the code scanners 57 to drive the code scanners 57 to approach the outer side of the soft-pack battery. The code scanners 57 are electrically connected with a control system and can scan the two-dimensional code on the outer side of the soft-pack battery. The number of the code scanners 57 is in a multiple relationship with the number of the positioning clamping jaws 531. In this embodiment, the number of the code scanners 57 is half of the number of the positioning clamping jaws 531. By arranging the clamp 53 with a plurality of positioning clamping jaws 531 on the platform 52, slidingly arranging the sliding plate 54 on the machine table 51, and arranging the plurality of code scanning cylinders 56 and the code scanners 57 on the sliding plate 54, the translation cylinder 55 is used to drive the sliding plate 54 to slide to the gap between the adjacent two clamps 53, and then the code scanning cylinders 56 are used to drive the code scanners 57 to extend into the gap to simultaneously scan each soft-pack battery on the clamp 53, thereby achieving the purpose of batch processing of the soft-pack batteries and greatly improving the production efficiency. By setting the number of the code scanners 57 to be half of the number of the positioning clamping jaws 531, the translation cylinder 55 is used to drive the code scanners 57 to scan the soft-pack batteries in half, and then the code scanners 57 are moved to the other half of the soft-pack batteries to scan, so that the number of the code scanning cylinders 56 and the code scanners 57 can be greatly reduced, the equipment cost is reduced, and the utilization rate of the code scanners 57 is greatly improved through two scanning to make up for the reduction of the code scanners 57, so that the production efficiency is ensured without affecting the production speed.
[0078] For example Figure 17As shown, the code scanning device 5 further comprises a conveying mechanism 58 arranged on the platform 52 to move the clamp 53 out of the platform 52. The arrangement of the conveying mechanism 58 can make the qualified soft-pack battery after code scanning be conveyed out quickly, reduce the difficulty of manual handling, improve the automation level and improve the production efficiency. Specifically, the conveying mechanism 58 comprises a conveying motor 581, a driving sprocket 582, a plurality of driven sprockets 583, a plurality of rollers 584 and a chain 585. The driving sprocket 582 is arranged on the output end of the conveying motor 581. The driven sprockets 583 are arranged on both sides of the platform 52 in an array. The rollers 584 are coaxially connected with the driven sprockets 583 one by one. The chain 585 is arranged between the driving sprocket 582 and the driven sprockets 583. The clamp 53 is carried on the rollers 584, and the conveying channels for conveying the clamp 53 are formed between the two rows of rollers 584. One end of the conveying channel is provided with a limiting piece 586. By arranging the limiting piece 586, the clamp 53 can be prevented from moving excessively, thereby improving the accurate positioning of the clamp 53 and making the code scanning of the code scanner 57 more accurate.
[0079] Further as shown Figure 17 and Figure 18 As shown, the code scanning device 5 further comprises a lifting mechanism 59. The platform 52 is vertically slidably arranged on the machine table 51. The lifting mechanism 59 is arranged on the machine table 51 and drives the platform 52 to lift. The lifting mechanism 59 is a lifting cylinder. The lifting mechanism 59 drives the platform 52 to lift, so that the soft-pack battery can be adjusted in height, thereby conveniently adjusting the height of the two-dimensional code of the soft-pack battery, ensuring that the two-dimensional code of the soft-pack battery is opposite to the code scanner 57, improving the accuracy of code scanning, and making the equipment applicable to soft-pack batteries of different sizes and having strong applicability. Specifically, the code scanning device 5 further comprises a guide mechanism 5010. The guide mechanism 5010 comprises guide columns 5011 and guide sleeves 5012. The guide columns 5011 are arranged on the platform 52 and distributed around the platform 52. The guide sleeves 5012 are arranged on the machine table 51. The guide columns 5011 are slidably sleeved in the guide sleeves 5012. The guide mechanism 5010 can make the platform 52 lift more stably.
[0080] Specifically, one side of the positioning clamp jaw 531 is provided with a window opposite to the soft-pack battery. In this way, the code scanner 57 can conveniently scan the code of the soft-pack battery, improving the convenience of operation. The upper side of the positioning clamp jaw 531 has a plurality of clamping fingers arranged in gaps. The arrangement of the clamping fingers can make the clamping fingers of the first transfer handling manipulator 3 and the second transfer handling manipulator 4 pass through the gaps between adjacent two clamping fingers, thereby achieving the purpose of grabbing the soft-pack battery and improving the convenience of grabbing.
[0081] In summary, the working principle of the soft package battery pressurization insulation test device 100 is described in detail as follows.
[0082] First, after the soft package battery is positioned on the positioning device 1, the translation driving device 20 drives the base 11 and the soft package battery thereon to approach the pressurization piercing device 2. The first transfer handling manipulator 3 takes out all the soft package batteries on the positioning device 1 at one time and transfers them to the pressurization piercing device 2, which pressurizes the soft package batteries and performs short circuit test. After the test is completed, the second transfer handling manipulator 4 takes out all the soft package batteries on the pressurization piercing device 2 at one time and transfers them to the code scanning device 5. The code scanning device 5 scans the codes of each soft package battery. Then, the second transfer handling manipulator 4 takes out all the soft package batteries of the code scanning device 5 at one time and transfers them to the clamps 53 of the matching workstations 6. Then, after the code scanning device 5 scans the second batch of soft package batteries, the third transfer handling manipulator 8 takes out the unqualified batteries on the code scanning device 5 or the matching workstations 6 and transfers them to the clamps 53 of the battery waste removal mechanism 7. When the clamps 53 are full, the unqualified batteries are transported away. When there is a battery vacancy in the clamps 53 of the code scanning device 5 due to waste removal, the third transfer handling manipulator 8 supplements the qualified batteries on the matching workstations 6 to the clamps 53 of the code scanning device 5. When the clamps 53 of the code scanning device 5 are full of qualified soft package batteries, the code scanning device 5 transports the full clamps 53 out and brings in new clamps 53.
[0083] The working principle of the positioning device 1 is as follows: after the soft package battery is loaded and placed in the clamping groove 18, the first driving cylinder 16 and the second driving cylinder 17 are started at the same time, driving the first push plate 14 and the second push plate 15 to move towards each other. The first push plate 14 and the second push plate 15 push the soft package battery between them to move and align with each other. In this process, the translation driving device 20 is started, and the driving motor 201 drives the belt 204 to rotate, so that the belt 204 drives the base 11 to translate. Therefore, the base 11 moves towards the pressurization piercing device 2 in the direction.
[0084] The working principle of the pressurized piercing device 2 is as follows: after the soft package battery is loaded and placed in the accommodating groove 216, the motor 2121 is started to drive the driving gear 2126a to rotate, the driving gear 2126a drives the lead screw 2122 to rotate through the intermediate gear 2126c and the driven gear 2126b, the lead screw 2122 drives the driving plate 2124 to translate through the nut 2123, the driving plate 2124 pushes the pressing plate 213 through the push rod 2125, and the pressing plate 213 moves towards the direction of the pressing block 214. Finally, the pressing plate 213 extrudes the pressing block 214 together, and a certain pressure is applied to the soft package battery. Then, the first cylinder 223 is started to push the first sliding plate 222 to slide on the support 221, and at the same time, the second cylinder 2211 pushes the second sliding plate 2210 to slide on the support 221, thereby driving the first clamping block 225 and the second clamping block 226 to approach each other, thereby clamping the soft package battery. When the first clamping block 225 and the second clamping block 226 continue to approach each other, the bayonet pierces through the through hole 2251 of the first clamping block 225 and enters the avoiding groove 2261 of the second clamping block 226, and in this process, the bayonet pierces the air bag of the soft package battery. And the bayonet extends into the soft package battery and makes conductive contact with the aluminum plastic film. At the same time, the horizontal movement driving cylinder 2292 drives the installation support 2291 to approach the tab of the soft package battery. The double-output clamping cylinder 2293 drives two clamping blocks 2294 to clamp the positive electrode and the negative electrode of the same soft package battery, so that the positive electrode conductive terminal 2295 on the clamping block 2294 makes conductive contact with the positive electrode of the soft package battery, and the negative electrode conductive terminal 2295 on the clamping block 2294 makes conductive contact with the negative electrode of the soft package battery. At this time, the short circuit test of the soft package battery can be performed.
[0085] The working principle of the code scanning device 5 is as follows: the conveying motor 581 is started to drive the driven sprocket 583 through the chain 585, thereby driving the plurality of rollers 584 to roll, so that the external clamp 53 can be conveyed to the platform 52. Then, the soft package battery is loaded onto the clamp 53. Next, the lifting mechanism 59 is started to drive the platform 52 to adjust the height, so that the height of the soft package battery matches the height of the code scanner 57. Then, the code scanning cylinder 56 drives the code scanner 57 to extend into the gap between the two adjacent positioning clamping jaws 531, so that the code scanner 57 can scan the two-dimensional code on one half of the soft package battery. After the first scanning is completed, the code scanning cylinder 56 drives the code scanner 57 to reset. Then, the translation cylinder 55 drives the sliding plate 54 to move a distance equal to the distance between two positioning clamping jaws 531. Then, the code scanning cylinder 56 drives the code scanner 57 to extend into the gap between the other two adjacent positioning clamping jaws 531, so that the code scanner 57 can scan the two-dimensional code on the other half of the soft package battery. After the second scanning is completed, the code scanning cylinder 56 drives the code scanner 57 to reset.
[0086] Compared with the prior art, the present application is characterized in that the positioning device 1, the pressure piercing device 2, the code scanning device 5 and the pairing station 6 are arranged in sequence in the transverse direction, a plurality of battery clamps 53 can be arranged on the positioning device 1, the pressure piercing device 2, the code scanning device 5 and the pairing station 6, and the first transfer manipulator 3 is arranged above the first four devices, and the soft package battery is transferred from the positioning device 1 to the pressure piercing device 2 by the first transfer manipulator 3. Therefore, the positioning device 1 can be used to automatically position each battery. Then, the second transfer manipulator 4 is used to transfer the soft package battery from the pressure piercing device 2 to the clamp of the code scanning device 5, and then the pressure piercing device 2 is used to pierce and test the insulation of each battery, and then the battery after the test is automatically transferred to the code scanning device 5 for code scanning. In addition, the third transfer manipulator 8 is arranged above the code scanning device 5 and the pairing station 6, and the third transfer manipulator 8 is used to sort the soft package batteries after code scanning, so that the soft package batteries can be automatically screened, and the whole process is controlled by the control system to automatically load, transfer, test and sort and unload, so that manual operation is not required, and full-automatic production is realized. In addition, a plurality of battery clamps can be arranged on each device to simultaneously perform the operation, and the production efficiency is extremely high.
