[0057] This embodiment provides a casing device that can prevent downward pressure from damaging the core 300, thus ensuring the quality of the finished battery cell. Figure 1 and Figure 2 As shown, the housing insertion device includes a support assembly 10, a pressing mechanism 20, a steel housing fixture 30, and a core loading mechanism 40. The pressing mechanism 20 includes a pressing drive assembly 21, a pressure rod 22, and a pressure sensor 23. The pressing drive assembly 21 is installed on the support assembly 10, and the output end of the pressing drive assembly 21 is connected to the pressure sensor 23 and the pressure rod 22 in sequence. The pressing drive assembly 21 can drive the pressure rod 22 and the pressure sensor 23 to move in the vertical direction. The steel housing fixture 30 is installed on the support assembly 10 and has a fixed position 31. The steel housing 200 can be positioned at the fixed position 31, which is located below the pressure rod 22. The core loading mechanism 40 is configured to place the core 300 into the positioned steel housing 200.

[0058] The shell-entering device is provided with a pressure sensor 23 between the output end of the downward driving assembly 21 and the pressing rod 22. After the roll core loading mechanism 40 puts the roll core 300 into the steel shell 200, the downward driving assembly 21 drives the pressing rod 22 to press down, so as to close the steel shell 200. The top of the steel shell 200 provides an opposite force to the pressing rod 22, and the pressing rod 22 transmits the opposite force to the pressure sensor 23. The pressure sensor 23 can detect the size of the force. When the force exceeds a preset value, the pressing is stopped, which indicates that the sealing is in place and the pressing is stopped in time, so that the roll core 300 in the steel shell 200 is not damaged due to excessive pressure, and the quality of the finished product is improved.

[0059] Optionally, as shown in Figure 1 and Figure 2 , the downward driving assembly 21 comprises a mounting frame 211, a driving member 212, a lead screw 213 and a clamping block 215. The mounting frame 211 is mounted on the support assembly 10. The driving member 212 is mounted on the mounting frame 211. The lead screw 213 is mounted on the output end of the driving member 212 and extends in the vertical direction. The driving member 212 can drive the lead screw 213 to rotate. The nut assembly 214 is threadedly connected to the lead screw 213 and is in sliding fit with the mounting frame 211 in the vertical direction. The pressing rod 22 is fixedly provided through the clamping block 215. The two ends of the pressure sensor 23 are connected to the clamping block 215 and the nut assembly 214, respectively. Through the above arrangement, the driving member 212 drives the lead screw 213 to rotate, and then drives the nut 2141 to move in the vertical direction. In other embodiments, the driving of the pressing rod 22 to move up and down can also be achieved by a gas cylinder or other driving forms, which are not limited here.

[0060] Optionally, as shown in Figure 1 and Figure 2 , the nut assembly 214 comprises a nut 2141 and a connecting block 2142. The nut 2141 is threadedly connected to the lead screw 213. The connecting block 2142 is connected to the nut 2141. The connecting block 2142 is in sliding fit with the mounting frame 211. The pressure sensor 23 is connected between the connecting block 2142 and the clamping block 215. Through the above arrangement, the accuracy of the movement of the nut assembly 214 in the vertical direction is ensured.

[0061] Optionally, as shown in Figure 1 and Figure 2As shown, the pressing mechanism 20 further comprises a position sensing assembly 24, the position sensing assembly 24 comprising a second sensing member 242 and three first sensing members 241, the three first sensing members 241 being spaced apart in a vertical direction on the mounting frame 211; the second sensing member 242 being connected to the nut assembly 214, specifically, the second sensing member 242 being connected on the connecting block 2142 and being able to pass through the three first sensing members 241 in sequence, the first sensing members 241 or the second sensing member 242 being in communication connection with the driving member 212. Through the above arrangement, when the second sensing member 242 passes through the lowest first sensing member 241, it indicates that the pressing rod 22 has been pressed to the lowest point and does not need to be pressed further, the driving member 212 stops driving, when the second sensing member 242 passes through the highest first sensing member 241, the pressing rod 22 is in a avoiding position and is far away from the fixed position 31, when the second sensing member 242 passes through the middle first sensing member 241, the pressing rod 22 is lowered to a position close to the fixed position 31, so that the stroke of the driving member 212 is limited, avoiding the pressing rod 22 being pressed too much or being raised too high, affecting the sealing efficiency.

[0062] Optionally, as shown in Figure 2 , one of the first sensing member 241 and the second sensing member 242 is a photoelectric sensor, and the other is a baffle, the photoelectric sensor is provided with a sensing groove 2411, and the baffle passes through the sensing groove 2411, the photoelectric sensor is triggered. In other embodiments, the first sensing member 241 and the second sensing member 242 can also be other sensing forms, which are not limited here.

[0063] Optionally, as shown in Figure 1 , the support assembly 10 comprises a fixed table plate 11 and a first rotating table plate 12, the pressing driving assembly 21 (specifically, the mounting frame 211) being installed on the fixed table plate 11; the first rotating table plate 12 being annular around the fixed table plate 11 and being able to rotate intermittently relative to the fixed table plate 11, the steel shell jig 30 being installed on the first rotating table plate 12, the steel shell jig 30 being able to clamp or release the steel shell 200 at the fixed position 31. Through the above arrangement, the steel shell jig 30 can rotate intermittently, when the steel shell jig 30 rotates to other positions, the steel shell 200 can be fed by a mechanical hand or manually, improving the continuity of the whole device.

[0064] Optionally, the steel shell jig 30 is a clamping jaw air cylinder, which is relatively common in the prior art and is not described here.

[0065] Optionally, as shown in Figure 2 and Figure 3As shown, the shell-entering device further comprises a supporting assembly 50, which comprises a supporting driving member 51 and a supporting rod 52. The supporting driving member 51 is installed at the lower side of the fixed table plate 11. The supporting rod 52 is connected to the output end of the supporting driving member 51 and is located at the lower side of the fixed position 31. The supporting driving member 51 can drive the supporting rod 52 to abut against or move away from the bottom of the fixed steel shell 200. Through the above arrangement, when the pressing rod 22 is pressed, the supporting driving member 51 drives the supporting rod 52 to abut against the bottom of the steel shell 200, preventing the force of the pressing rod 22 from being too large to damage the steel shell 200.

[0066] It should be noted that the connection between the supporting driving member 51 and the fixed table plate 11 is not shown here and can be achieved by using some fixed connecting plates.

[0067] Optionally, referring to Figure 1 , Figure 3 and Figure 4 , the roll core loading mechanism 40 comprises a fixed frame 41, a lifting assembly 42 and a roll core jig assembly 43. The fixed frame 41 is arranged opposite to the supporting assembly 10. The lifting assembly 42 comprises a lifting driving member 421, a cam plate 422 and a limiting plate 423. The cam plate 422 and the limiting plate 423 are connected to the output end of the lifting driving member 421. The limiting plate 423 is provided with a limiting hole 4231. The lifting driving member 421 can drive the cam plate 422 and the limiting plate 423 to rise so that the limiting hole 4231 is located above the steel shell jig 30. The roll core jig assembly 43 comprises a second rotating table plate 431, a floating connecting member 432, a cam 433 and a roll core jig 434. The floating connecting member 432 is floatingly connected to the second rotating table plate 431. The roll core jig 434 is connected to the floating connecting member 432. The cam 433 is rotatably connected to the lower side of the floating connecting member 432. The second rotating table plate 431 can rotate relative to the center of the cam plate 422 so that the cam 433 rolls along the top of the cam plate 422 to lift the roll core jig 434 above the limiting plate 423. Through the above arrangement, the roll core 300 can be loaded by a mechanical hand or manually when the second rotating table plate 431 is rotated to other positions, improving the continuity of the operation of the device. At the same time, since the position of the roll core 300 loaded by the mechanical hand or manually is relatively low, the structure of the cam plate 422 and the cam 433 is adopted. When the second rotating table plate 431 is rotated so that the roll core jig 434 is above the limiting plate 423, the floating connecting member 432 is appropriately lifted, which meets the relatively low operation height of the roll core jig 434 and the relatively high operation height of the roll core jig 434 for loading the steel shell 200. At the same time, the limiting hole 4231 provided in the limiting plate 423 enables the roll core 300 to fall into the steel shell 200 accurately and without error.

[0068] The roll core jig 434 is a clamping jaw cylinder, which is common in the prior art and will not be described herein.

[0069] Optionally, the roll core jig 434, the limiting hole 4231, the pressing rod 22 and the steel shell jig 30 are provided with two. Through the above arrangement, the assembly of at least two battery cells can be realized at one time. In the embodiment, the number is set to two, and in other embodiments, it can also be three, four or more, which is not limited. Adaptively, the downward driving assembly 21 and the position sensing assembly 24 are also provided with at least two.

[0070] Optionally, the roll core loading mechanism 40 further comprises a connecting seat 44, which comprises a first plate 441, a second plate 442 and a third plate 443 connected vertically in sequence. The first plate 441 is connected with the second rotating table plate 431, the floating connecting piece 432 is slidingly matched with the second plate 442, and the third plate 443 and the floating connecting piece 432 are connected through the elastic piece 45. Through the above arrangement, the floating connection between the floating connecting piece 432 and the second rotating table plate 431 is realized, and the direction of the floating connecting piece 432 is ensured not to be skewed during the floating process.

[0071] Optionally, the supporting driving piece 51 and the lifting driving piece 421 are push rods, and the same driving source is adopted, which can ensure the consistency of the action and save the setting of the driving source.

[0072] The working process of the shell loading device will be described below. Figures 1-4 The working process of the shell loading device will be described below.

[0073] 1. When the roll core jig 434 is in other positions, the robot places the roll core 300 into the roll core jig 434; when the steel shell jig 30 is in other positions, the robot places the steel shell 200 into the steel shell jig 30;

[0074] 2. The lifting driving piece 421 drives the cam plate 422 and the limiting plate 423 to rise, so that the limiting plate 423 is above the supporting rod 52 and waits;

[0075] 3. With the rotation of the second rotating table plate 431, the cam 433 is rollingly matched with the upper edge of the cam plate 422, so that the floating connecting piece 432 drives the roll core jig 434 clamping the roll core 300 to rise until the roll core jig 434 reaches below the pressing rod 22, and the second rotating table plate 431 stops rotating;

[0076] 4. Synchronously with step 3, with the rotation of the first rotating table plate 12, the steel shell jig 30 is rotated to below the limiting plate 423, and the first rotating table plate 12 stops rotating;

[0077] 5. The core jig 434 loosens the core 300, and the core 300 falls into the steel shell 200 below through the limiting hole 4231;

[0078] 6. The supporting driving member 51 drives the supporting rod 52 to rise, so that the supporting rod 52 abuts against the bottom of the steel shell 200;

[0079] 7. The pressing driving assembly 21 drives the pressing rod 22 to press down, and the sealing of the steel shell 200 is completed;

[0080] 8. After the sealing is completed, the first rotating table plate 12 rotates to another position, the battery cell is loosened, and the discharging is performed.
