The material picking claw 21 is in an open state so that the first material picking rod 211 and the second material picking rod 212 clamp the lining 5. At the same time, the first material picking rod 211 and the second material picking rod 212 both hook the lining 5 through the hooking portion 213. When the material picking driving member 214 drives the first transmission plate 215 and the second transmission plate 216 to move closer to each other, the first material picking rod 211 and the second material picking rod 212 can be withdrawn from the notch of the lining 5, and the material picking claw 21 is in a closed state to release the lining 5.

[0046] In a preferred embodiment, a lifting seat 221 is provided on the side of the material-collecting claw 21 away from the flipping clamp 11, and a plurality of material-collecting seats are installed on the lifting seat 221 at intervals.

The scraper assembly 3 includes a material receiving sheet metal 31, which is specifically a concave plate arranged horizontally and is at the bottom of the clamping assembly 1. In a preferred embodiment, the size of the material receiving sheet metal 31 is adapted to the size of the liner 5, so that when the liner 5 falls to the material receiving sheet metal 31, the material receiving sheet metal 31 can play a certain role in regularizing the liner 5, which is conducive to improving the convenience of subsequent sheet metal collection operations. A through hole 311 is opened on the material receiving sheet metal 31, and the through hole 311 is specifically a long strip. The first material taking rod 211 and the second material taking rod 212 are driven by the lifting drive member 22 to pass through the through hole 311 to take out the liner 5 in the plastic shell 6.

[0048] In the process of taking out the liner 5, the clamping cylinder 114 drives the two clamping plates 111 to clamp the plastic shell 6, and the plastic shell 6 remains open toward the receiving sheet metal 31, and the flipping clamp 11 fixes the plastic shell 6. The lifting drive drives the lifting seat 221 to rise, and the lifting seat 221 drives the material-taking claw 21 to pass through the through hole 311 to approach the plastic shell 6.

The operation of picking up the liner 5 by the material picking claw 21 is efficient and quick, which is beneficial to improving production efficiency. After the liner 5 is removed from the plastic shell 6, the loading and battery cell assembly process can be entered in time, reducing the possibility of debris entering the plastic shell 6. The interior of the plastic shell 6 remains relatively clean to improve the occurrence of micro-short circuits, puncture of the diaphragm, self-discharge and other phenomena in the battery cell, thereby improving the performance and quality of the product.

[0049] Embodiment 2:

[0050] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the scraper assembly 3 of the utility model, see Figure 6-8 .

[0051] The receiving sheet metal 31 of this embodiment includes a discharge end 312. After the liner 5 falls onto the receiving sheet metal 31, it is discharged from the discharge end 312. The receiving sheet metal 31 is provided with a baffle plate 313 at the discharge end 312. The baffle plate 313 is a semi-arc plate and is located at the top of the receiving sheet metal 31. When the liner 5 is discharged from the discharge end 312, the baffle plate 313 can limit the path of the liner 5 to be dropped so as to collect the liner 5 uniformly. A scraping sheet metal 32 is provided in the receiving sheet metal 31. The scraping sheet metal 32 pushes the liner 5 that falls onto the receiving sheet metal 31 out of the discharge end 312, and the liner 5 is discharged.

[0052] In a preferred embodiment, the scraper sheet metal 32 includes a scraper section 321 and a connecting section 322. The scraper section 321 is a vertically arranged long plate and is adapted to the receiving sheet metal 31 so as to push the liner 5 off from the discharge end 312 at one time. The connecting section 322 is transmission-connected with a scraper drive member 33. The scraper drive member 33 preferably, but not limited to, adopts a linear module. The scraper drive member 33 drives the connecting section 322 to move and then drives the scraper section 321 to move along the receiving sheet metal 31. The scraper section 321 scrapes the liner 5 at the receiving sheet metal 31 and pushes the liner 5 off from the discharge end 312 to collect the liner 5.

[0053] In a preferred embodiment, the receiving sheet metal 31 is provided with a material storage assembly 4 below the material discharge end 312, and the material storage assembly 4 includes a receiving pipe 41, which is a vertically arranged square pipe, and a channel for collecting the liner 5 is formed in the receiving pipe 41. The scraping sheet metal 32 scrapes the liner 5 from the material discharge end 312, and the liner 5 falls into the receiving pipe 41. Specifically, a receiving box is provided at the bottom of the receiving pipe 41 to collect the liner 5 falling through the receiving pipe 41.

[0054] In a preferred embodiment, a buffer port 411 is provided on the receiving tube 41, and a buffer baffle 42 is provided in the buffer port 411 of the receiving tube 41, and the buffer baffle 42 is adapted to the buffer port 411. A buffer drive assembly 43 is connected to the buffer baffle 42 in a transmission manner, and the buffer drive assembly 43 can drive the buffer baffle 42 to enter or exit the receiving tube 41 through the buffer port 411. In some specific embodiments shown, the buffer drive assembly 43 includes a guide seat 432, which is installed on one side of the buffer baffle 42, and the guide seat 432 is slidably connected to a guide rail 431, and the guide rail 431 cooperates with the guide seat 432 to guide the movement of the buffer baffle 42. A bottom plate 433 is provided on the side of the guide rail 431 away from the guide seat 432. One end of the guide seat 432 away from the cache baffle 42 is transmission-connected to a cache cylinder 434 , and the cache cylinder 434 drives the guide seat 432 to slide along the guide rail 431 , and then drives the cache baffle 42 to enter the material receiving pipe 41 through the cache opening 411 .

[0055] When the liner 5 fills the receiving box, the cache drive assembly 43 drives the cache baffle 42 to enter the receiving pipe 41 through the cache port 411. The cache baffle 42 can receive the continuously falling liner 5 to prevent the liner 5 from continuing to fall into the receiving box along the receiving pipe 41. At this time, the empty receiving box is replaced, and the cache drive assembly 43 drives the cache baffle 42 to exit the receiving pipe 41 through the cache port 411, and the liner 5 continues to fall into the receiving box. The cache assembly can cache the liner 5, and the receiving box can be replaced without stopping during the automatic liner 5 removal process, which is conducive to improving the convenience of liner 5 unloading and the efficiency of the automatic liner 5 removal operation, so as to further ensure that the plastic shell 6 can enter the subsequent loading process in time.

[0056] Embodiment 3:

[0057] The difference between this embodiment and the above embodiment is that this embodiment further optimizes the structure of the clamping assembly 1 of the utility model, see Fig. 9 .

[0058] In this embodiment, a material taking area 12 is formed on one side of the receiving sheet metal 31, and the plastic shell 6 takes out the liner 5 in the material taking area 12. The clamping assembly 1 of this embodiment includes a flip assembly 13 for driving the flipping jaw 11 to flip, and the flip assembly 13 includes a rotating rod 131, which is specifically arranged horizontally, and a plurality of flipping jaws 11 are spaced and distributed along the axis direction of the rotating rod 131 and the rotation direction of the rotating rod 131, and form a plurality of groups of flipping jaws 11. A bracket 1321 is arranged on one side of the rotating rod 131, and the rotating rod 131 is rotatably connected to the bracket 1321. Specifically, the rotating rod 131 can be rotatably connected to the bracket 1321 through a bearing, and the rotating rod 131 is transmission-connected to a flip servo motor 1322 for driving the rotating rod 131 to rotate. It can be understood that this is not a specific limitation on the flip driving source, and in other preferred embodiments, a pneumatic swing table or an electric swing table can be used. The flip servo motor 1322 drives the rotating rod 131 to rotate, thereby flipping the flip jaw 11 clamping the plastic shell 6 to the material taking area 12, and making the opening of the plastic shell 6 face the receiving sheet metal 31.

[0059] While the material taking component 2 takes out the liner 5, the plastic shell 6 of the next batch of liner 5 to be taken can be clamped into the empty flipping jaw 11, and the rotating rod 131 drives the flipping jaw 11 that has clamped the plastic shell 6 to flip to the material taking area 12 to continuously take out the liner 5, and the clamping component 1 continuously loads the plastic shell 6, which is beneficial to further improve the efficiency of taking out the liner 5 and save labor costs.
