Referring to fig. 1, a battery cell assembling apparatus 10 according to a preferred embodiment of the present invention includes a pressurizing mechanism 100, a carrier 200, and a conveying mechanism 300.

The battery cell assembling apparatus 10 may be mounted on a rack or a workbench of a production line. The battery cell assembling equipment 10 has a pressure maintaining station, and the pressurizing mechanism 100 can apply pressing force to the battery cell module located at the pressure maintaining station along the length direction, so that the battery cell module is compressed and pressure maintained. As shown in fig. 15, the cell module 20 is formed by bonding a plurality of cells 21, and the longitudinal direction thereof refers to the arrangement direction of the plurality of cells 21.

The carrier 200 is used for carrying the assembled battery cell module 20. The carriers 200 include a plurality of carriers 200, and each of the carriers 200 can be carried by the conveying mechanism 300 and conveyed along a predetermined conveying path under the driving of the conveying mechanism 300. The transmission mechanism 300 may adopt a speed-doubling chain structure, and the carriers 200 can be sequentially transmitted to the pressure maintaining station, so that the pressure maintaining mechanism 100 can perform the pressure maintaining operation on the battery cell modules 20 loaded thereon.

Referring to fig. 2, 3, 6 and 8, the pressing mechanism 100 includes a support 110 and a rotary driving member 120. Wherein, the rotating shaft of the rotary driving member 120 is provided with an abutting member 121.

The support 110 plays a role in fixing and supporting, and may be a gantry structure. The rotary drive 120 may be a power assembly such as a rotary cylinder, motor, etc. The docking member 121 may be a pin, a bump, or the like, and is capable of being mated with the mating member 211 on the carrier 200. Generally, the convex area of the docking element 121 corresponds to the concave area of the mating element 211, and the docking element 121 and the mating element 211 may be of corresponding male and female structures. When the abutting member 121 and the mating member 211 approach each other gradually, the abutting is achieved, so that the torque of the rotary driving member 120 can be transmitted to the mating member 211 through the abutting member 121. And when the two parts are far away, the two parts can be automatically separated.

The carrier 200 includes a screw 210 and a clamping member 220. Wherein the clamping member 220 forms a clamping portion 201 for accommodating the cell module 20. Furthermore, the clamping member 220 is in transmission connection with the lead screw 210 through a nut seat (not shown), and the clamping member 220 can adjust the size of the clamping portion 201 along with the rotation of the lead screw 210. The carrier 200 generally further includes a tray 230 for supporting and carrying, and the cell module 20 is carried on the tray 230 and clamped in the clamping portion 201.

Specifically, in the present embodiment, the clamping member 220 includes a first clamping plate 221 and a second clamping plate 222, and the clamping portion 201 is formed between the first clamping plate 221 and the second clamping plate 222. The first clamping plate 221 is fixedly disposed on the tray 230, and the second clamping plate 222 is disposed opposite to the first clamping plate 221 and slidably mounted on the tray 230. Moreover, the second clamping plate 222 is in transmission connection with the screw rod 210 through a nut seat, and the rotation of the screw rod 210 can drive the second clamping plate 222 to be close to or far from the first clamping plate 221, so that the size of the clamping part 201 can be adjusted.

Specifically, the clamping member 220 further includes a moving plate 223, and the moving plate 223 is slidably mounted to the tray 230 through a guide rail. The nut seat is embedded in the moving plate 223, and the second clamping plate 222 is fixedly disposed on the moving plate 223. In this manner, the second clamping plate 222 can be made more stable when moving relative to the first clamping plate 221.

Further, a fitting member 211 capable of fitting with the docking member 121 is provided at one end of the screw rod 210. Moreover, when the carrier 200 is transferred to the pressure maintaining station by the transfer mechanism 300, the docking member 121 is docked with the mating member 211 of the carrier 200. Thus, the pressurizing mechanism 100 can be linked with the screw rod 210, and further the clamping portion 201 is clamped by driving the screw rod 210 to rotate, so as to clamp and maintain the pressure of the battery cell module 20 on the carrier 200.

In the present embodiment, the pressing mechanism 100 further includes a displacement sensor 111 fixedly disposed on the support 110, and the displacement sensor 111 is configured to detect a displacement amount of the clamping member 220. Through the displacement volume that detects clamping piece 220, can monitor the pressure of electricity core module 20 in real time to the pressure control with the pressurize is in suitable within range conveniently.

Referring to fig. 7, in the present embodiment, the docking member 121 is a first rotating wheel fixedly disposed on the rotating shaft of the rotating driving member 120, a latch 1211 extending along the axial direction of the rotating shaft is fixedly disposed on the first rotating wheel, the fitting member 211 is a second rotating wheel having a groove 2111, and the latch 1211 can be inserted into the groove 2111 to dock the docking member 121 and the fitting member 211.

The first pulley is generally coaxial with the axis of rotation of the rotary drive member 120, and the number of latches 1211 is at least two. The second wheel may be identical in construction to the first wheel and is generally coaxial with the lead screw 210. Also, the number of grooves 2111 corresponds to the number of pins 1211 on the first wheel. Thus, when the first runner is butted with the second runner, the reliability of torque transmission is higher.

It should be noted that in other embodiments, the docking member 121 and the mating member 211 may have other configurations. For example, the abutting member 121 and the mating member 211 may be splines capable of engaging with each other, and when the two abut against each other, the abutting is realized and torque is transmitted, and when the two separate from each other, the two separate from each other automatically.

In the present embodiment, the pressing mechanism 100 has a retracted state and a pressed state. When the pressing mechanism 100 is in the avoiding state, the abutting piece 121 can avoid the carrier 200 conveyed along the conveying path; when the pressurizing mechanism 100 is in the pressurizing state, the abutting piece 121 can be abutted with the engaging piece 211 of the carrier 200 located at the pressure holding station.

That is, the position of the rotary drive 120 is not fixed, but can be adjusted as desired. When the carrier 200 carrying the cell module 20 to be pressure-maintained is transferred to the pressure-maintaining station, the pressure mechanism 100 may be switched to the pressure-maintaining state. At this time, the fitting piece 211 of the carrier 200 reaching the pressure maintaining station can be smoothly butted with the butting piece 121 at the end of the rotating shaft of the rotary driving piece 120, so that the pressure maintaining operation of the cell module 20 by the pressurizing mechanism 100 is facilitated. When the pressure maintaining operation is completed, the pressurizing mechanism 100 can be switched to the avoiding state. At this time, the carrier 200 can be driven by the conveying mechanism 300 to continue to be transferred to the next process along the conveying path, so that the efficiency is further improved.

It should be noted that in other embodiments, the pressurization mechanism 100 may be maintained in a pressurized state. After the cell module 20 is pressurized, the carrier 200 may be manually transferred to a designated station or a production line.

Further, in the present embodiment, the pressing mechanism 100 further includes a first driving member 130, a first mounting seat 140, a second driving member 150, and a second mounting seat 160. Wherein:

the first driving member 130 is fixedly disposed on the support 110 and can be driven along a first direction perpendicular to the extending direction of the rotation axis of the rotary driving member 120. The first driving member 130 may be a linear cylinder, and the first direction may be a vertical direction as shown in fig. 2. The first mounting seat 140 is slidably disposed on the support 110 along a first direction and is in transmission connection with a driving end of the first driving member 130. Specifically, the first mounting seat 140 may be mounted to the support 110 by a slide rail. Therefore, the first driving member 130 can drive the first mounting base 140 to ascend and descend along the first direction.

The second driver 150 may also be a linear cylinder. The second driving member 150 is fixed to the first mounting base 140. Therefore, the second driving member 150 can be lifted and lowered along the first direction with the first mounting base 140. The second driver 150 is capable of being driven in a second direction that is the same as the direction in which the shaft of the rotary driver 120 extends. Specifically, the first direction is perpendicular to the second direction, and the second direction may be a horizontal direction as shown in fig. 2. The second mounting seat 160 is slidably disposed on the first mounting seat 140 along the second direction and is in transmission connection with the driving end of the second driving member 150. Similarly, the second mounting base 160 can be mounted to the first mounting base 140 by a sliding rail. Therefore, the second driving member 150 can drive the second mounting seat 160 to move along the second direction, so as to drive the docking member 121 to dock with the mating member 211.

The rotary driving member 120 is fixedly disposed on the second mounting seat 160. Therefore, with the actions of the first driving element 130 and the second driving element 150, the rotary driving element 120 is driven to translate and lift in the first direction and the second direction, so as to switch the pressurizing mechanism 100 between the avoiding state and the pressurizing state.

In this embodiment, the docking member 121 can elastically float in the extending direction of the rotation shaft of the rotary driving member 120.

The elastic floating means that the abutting part 121 can be stretched in a certain range under the action of an axial acting force, and can be reset after the acting force is eliminated. When mating member 211 is mated with mating member 121, it may not be possible to ensure that the convex region of mating member 121 is aligned with the concave region of mating member 211 (latch 1211 is exactly aligned with recess 2111) each time.

In this case, when the fitting member 211 presses against the abutting member 121, the abutting member 121 is first forced to elastically retract. Then, the rotary driving member 120 rotates the docking member 121 until the latch 1211 is aligned with the notch 2111. At this time, the docking member 121 is reset and the latch 1211 is automatically inserted into the groove 2111, and the mating member 211 is docked with the docking member 121. It can be seen that the mating member 211 and the mating member 121 are smoothly mated with higher reliability.

Referring to fig. 4 and 5, in the embodiment, the pressing mechanism 100 further includes a connecting rod 180 and a first spring 190. Wherein:

the connecting plate 170 is fixedly disposed at the driving end of the second driving member 150. The link 180 extends in a second direction, i.e., the rotational axis of the rotary drive 120. Second mount 160 is slidably coupled to web 170 in a second direction via link 180. Specifically, the connecting rod 180 may be fixed to the connecting plate 170 and slidably disposed through the second mounting seat 160; alternatively, the connecting rod 180 is fixed to the second mounting seat 160 and slidably disposed through the connecting plate 170. The first spring housing 190 is disposed on the connecting rod 180 and clamped between the second mounting seat 160 and the connecting plate 170.

When the docking member 121 is subjected to an axial force, the second mount 160 slides along the link 180 and compresses the first spring 190. Thus, the elastic floating of the docking member 121 can be achieved.

Referring to fig. 1 again and fig. 9 and 10 together, in the present embodiment, the battery cell assembling apparatus 10 further includes shaping mechanisms 400 disposed at two opposite sides of the pressure maintaining station, and each shaping mechanism 400 includes a mounting seat 410, a horizontal pressing assembly 420, and a vertical pressing assembly 430. Wherein:

the mounting block 410 is a supporting structure and may be a metal plate structure. The horizontal pressing assembly 420 can extrude the cell module 20 along the width direction of the cell module 20 located at the pressure maintaining station; the vertical compressing assembly 430 can extrude the cell module 20 along the height direction of the cell module 20 located at the pressure maintaining station. The width direction of the cell module 20 refers to the vertical direction as shown in fig. 1, and the height direction of the cell module 20 refers to the direction perpendicular to the plane of the drawing as shown in fig. 1.

Shaping mechanism 400 carries out the plastic operation to the electric core module 20 of pressurize station, compresses tightly subassembly 420 and the vertical extrusion that compresses tightly subassembly 430 down at the level, can follow all directions flattening with outside outstanding electric core 21 in the electric core module 20 to make a plurality of electric cores 21 in the electric core module 20 can keep on same straight line, help promoting electric core module 20's quality.

In the present embodiment, the pressing force of the horizontal pressing component 420 of the shaping mechanism 400 on one side of the pressure maintaining station is greater than the pressing force of the horizontal pressing component 420 of the shaping mechanism 400 on the other side.

When the shaping operation is performed, the shaping mechanism 400 with a large extrusion force can push the battery cell module 20 to move towards the shaping mechanism 400 with a small extrusion force. Therefore, the shaping mechanism 400 with a large pressing force can be used as a positioning reference in the shaping process, so that the positions of all the shaped battery cell modules 20 on the carrier 200 can be kept consistent, thereby facilitating the execution of the subsequent processes.

Referring to fig. 11 and 12, in the present embodiment, the horizontal pressing assembly 420 includes a first bracket 421, a horizontal driving member 422, and a shaping block 423. The first support 421 can be slidably mounted on the mounting seat 410 along the width direction of the battery cell module 20 through a wire-rail slider structure; the horizontal driving member 422 may be an air cylinder, which is fixed to the mounting base 410 and used for driving the first support 421 to slide; the shaping block 423 is generally a long-strip-shaped block structure, and extends along the length direction of the cell module 20, and the shaping block 423 may be fixed to one side of the first support 421 facing the cell module 20 through a screw fastening or the like. Along with horizontal drive 422 drive first support 421 slides, shaping piece 423 can extrude the side of battery cell module 20 to realize the plastic.

Further, the vertical pressing assembly 430 includes a second bracket 435 and a vertical driving member 436. The second bracket 435 may also be slidably mounted on the first bracket 421 through a rail sliding block structure along the height direction of the battery cell module 20; the vertical driving member 436 may also be a cylinder, which is fixed to the first bracket 421. The abutting end of the vertical pressing assembly 430, that is, the end of the vertical pressing assembly 430 abutting against the cell module 20, is disposed at the driving end of the vertical driving member 436.

In this embodiment, the end of holding of vertical pressure subassembly 430 is equipped with gyro wheel 431, gyro wheel 431 can with be located the elasticity butt of the electric core module 20 of pressurize station, and gyro wheel 431 can roll along the length direction of electric core module 20 for electric core module 20.

When the vertical pressing assembly 430 applies a pressing force to the cell module 20, the roller 431 will directly contact the surface of the cell module 20. Because gyro wheel 431 has elasticity, so can play the cushioning effect when vertical compressing tightly subassembly 430 extrusion battery core module 20 to avoid crushing battery core module 20 because of gyro wheel 431 and the hard contact of battery core module 20. Moreover, the roller 431 can roll, and when the pressurizing mechanism 100 applies pressure to the battery cell module 20 and pushes the battery cell module 20 to compress tightly along the length direction, the battery cell module 20 can move along the length direction. At this time, the position of the roller 431 remains unchanged, and the roller 431 rolls relative to the surface of the cell module 20, so as to avoid damaging the cell module 20.

Referring to fig. 13 and 14, in the present embodiment, the vertical pressing assembly 430 includes a mounting sleeve 432, a guiding rod 433 and a second spring 434. Wherein:

the mounting sleeve 432 is a hollow structure, and the guide rod 433 is partially slidably inserted into the mounting sleeve 432. The roller 431 is mounted to an end of the guide rod 433 outside the mounting sleeve 432. The second spring 434 is accommodated in the mounting sleeve 432 and abuts against one end of the guide rod 433 away from the roller 431. The second spring 434 may provide an elastic supporting force to the guide rod 433, so that the roller 431 at the end thereof can be elastically abutted against the battery cell module 20. The mounting sleeve 432 may be a metal tubular structure with two ends or open ends.
