The second assembly mechanism 400 is used to assemble the battery units 4 assembled by the plurality of first assembly mechanisms 300 to form a battery pack 6.

[0120] The feeding mechanism 100 is used to carry the battery cells 1 and provide a plurality of battery cells 1 to the transmission mechanism 200.

[0121] In an embodiment of the present application, the feeding mechanism 100 may include a hoisting component to hoist a plurality of battery cells 1 onto the transmission mechanism 200; alternatively, the feeding mechanism 100 may include a pushing component to push a plurality of battery cells 1 onto the transmission mechanism 200.

[0127] The first assembly mechanism 300 is used to receive the battery cell 1 transported by the transmission channel 210 and assemble the battery cell 1 with the heat exchange plate 3 to form a battery unit 4.

[0128] In an embodiment of the present application, the battery unit 4 includes battery cells 1 and a heat exchange plate 3. The heat exchange plate 3 has opposite side surfaces in the thickness direction.

[0132] Referring to Figure 2 , Figure 2 is a partial structural schematic diagram of the transmission mechanism and the first assembly mechanism of the battery manufacturing device provided by some embodiments of the present application.

[0133] According to an embodiment of the present application, as Figure 1 and Figure 2 shown, the first assembly mechanism 300 includes a grouping mechanism 310 and an installation mechanism 320. The grouping mechanism 310 is arranged downstream of the transmission channel 210, and the grouping mechanism 310 is used to form a battery row 2 from the multiple battery cells 1 transported by the transmission channel 210. The installation mechanism 320 is arranged downstream of the grouping mechanism 310, and the installation mechanism 320 assembles the battery row 2 and the heat exchange plate 3 to form a battery unit 4.

[0134] In an embodiment of the present application, the first assembly mechanism 300 includes a grouping mechanism 310 and a mounting mechanism 320. The grouping mechanism 310 is disposed downstream of the transmission channel 210, and the grouping mechanism 310 is configured to form a plurality of battery cells 1 transmitted by the transmission channel 210 into battery rows 2 having a predetermined number.

[0135] Exemplarily, the grouping mechanism 310 has a receiving cavity, and a plurality of battery cells 1 transmitted through the transmission channel 210 are conveyed into the receiving cavity to form battery rows 2.

[0136] Exemplarily, the grouping mechanism 310 has an inclined chute, and a plurality of battery cells 1 transmitted through the transmission channel 210 slide in the inclined chute to a predetermined position in sequence based on gravity to form battery rows 2.

[0137] In an embodiment of the present application, the mounting mechanism 320 is disposed downstream of the grouping mechanism 310, and the mounting mechanism 320 assembles the battery rows 2 formed by the grouping mechanism 310 with the heat exchange plate 3 to form a battery unit 4. The battery rows 2 and the heat exchange plate 3 can be assembled by connecting the battery rows 2 to the heat exchange plate 3 on both sides, or by connecting the battery rows 2 to one side of the heat exchange plate 3. There are various connection methods between the battery rows 2 and the heat exchange plate 3, such as welding, bonding, connecting members, etc.

[0138] In these alternative embodiments, through the cooperation of the grouping mechanism 310 and the mounting mechanism 320, a plurality of battery cells 1 are formed into battery rows 2, and then the battery rows 2 are assembled with the heat exchange plate 3 to form a battery unit 4, which facilitates the assembly of the battery rows 2 and the heat exchange plate 3 and is conducive to simplifying the formation of the battery unit 4.

[0139] According to an embodiment of the present application, as Figure 1 and Figure 2 shown, at least one first assembly mechanism 300 includes a film laying mechanism 330, which is disposed downstream of the mounting mechanism 320, and the film laying mechanism 330 is configured to attach a protective film 5 to the battery unit 4.

[0140] In an embodiment of the present application, at least one first assembly mechanism 300 includes a film laying mechanism 330. It can be understood that at least one of the plurality of first assembly mechanisms 300 includes a film laying mechanism 330.

[0141] Exemplarily, in the case where the battery manufacturing apparatus 1000 includes two first assembly mechanisms 300, one of the first assembly mechanisms 300 includes a film laying mechanism 330.

[0142] In an embodiment of the present application, the film laying mechanism 330 is disposed downstream of the installation mechanism 320. The film laying mechanism 330 is used to attach the protective film 5 to the battery unit 4, so that in the battery pack 6 formed by assembling a plurality of battery units 4, the protective film 5 is provided between two battery units 4. It can be understood that the battery unit 4 is disposed on the other side of the protective film 5 of the battery unit 4 containing the protective film 5, that is, the battery units 4 are provided on both sides of the protective film 5.

[0143] Exemplarily, the battery pack 6 includes N battery units 4 and N - 1 protective films 5, and the protective film 5 is provided between two adjacent battery units 4.

[0144] In these alternative embodiments, the corresponding film laying mechanism 330 can be set according to the assembly situation of the battery units 4, which improves the flexibility of the assembly of the battery units 4 and also speeds up the assembly efficiency of the battery units 4.

[0145] Referring to Figures 3 to 6 , Figure 3 is a partial front view of the transmission mechanism and the first assembly mechanism of the battery manufacturing device provided by some embodiments of the present application; Figure 4 is a schematic structural view of the first tray of the battery manufacturing device provided by some embodiments of the present application; Figure 5 is a front view of the first tray of the battery manufacturing device provided by some embodiments of the present application; Figure 6 is a top view of the first tray of the battery manufacturing device provided by some embodiments of the present application.

[0146] According to an embodiment of the present application, as Figure 2 and Figure 3 shown, the grouping mechanism 310 includes a rotary wheel feeder 311 and a first tray 312. The rotary wheel feeder 311 is disposed downstream of the transmission channel 210 and receives a plurality of battery monomers 1 in the transmission channel 210. The rotary wheel feeder 311 rotates along the first direction x, and the rotary wheel feeder 311 is provided with a plurality of mounting positions 3111 for carrying the battery monomers 1. The first tray 312 is used to receive a plurality of battery monomers 1 separated from the mounting positions 3111 and form a battery row 2.

[0147] In an embodiment of the present application, the rotating wheel distributor 311 is disposed downstream of the transmission channel 210 and can receive a plurality of battery cells 1 in the transmission channel 210 and drive the battery cells 1 to rotate. When rotating to a predetermined position, the battery cells 1 automatically detach due to gravity onto the first tray 312. With this arrangement, on the one hand, it can simplify the conveying method of the battery cells 1; on the other hand, after the rotating wheel distributor 311 drives the battery cells 1 to rotate by a certain angle, the battery cells 1 detach from the rotating wheel distributor 311 onto the first tray 312 based on their own gravity, reducing the use of other mechanisms. In addition, by arranging the rotating wheel distributor 311 between the first tray 312 and the transmission channel 210, it plays a certain buffering role for the battery cells 1.

[0148] Specifically, the rotating wheel distributor 311 rotates along the first direction x, and the first direction x can be clockwise rotation or counterclockwise rotation.

[0149] In an embodiment of the present application, the rotating wheel distributor 311 is provided with a plurality of mounting positions 3111 for carrying the battery cells 1, and the plurality of mounting positions 3111 are arranged at intervals along the circumferential direction of the rotating wheel distributor 311. Specifically, the transmission channel 210 communicates with the top of the rotating wheel distributor 311, and the first mounting position 3111 at the top carries one battery cell 1. As the rotating wheel distributor 311 rotates, the first mounting position 3111 gradually rotates towards the bottom until the battery cell 1 detaches from the first mounting position 3111 due to gravity, and the first mounting position 3111 continues to rotate to the top to receive a new battery cell 1. By such reciprocating motion, the transfer of a plurality of battery cells 1 is realized. The number of battery cells 1 detached from the rotating wheel distributor 311 can be controlled by controlling the rotation angle of the rotating wheel distributor 311, and thus the number of battery cells 1 in the battery string 2 can be controlled.

[0150] Exemplarily, the rotating wheel distributor 311 includes a rotating wheel body and a limiting plate. The rotating wheel body rotates clockwise. The limiting plate extends from the top of the rotating wheel body to the outer peripheral side of the rotating wheel body, and the limiting plate is spaced from the rotating wheel body in the radial direction. The projection of the limiting plate along the radial direction of the rotating wheel body covers a part of the outer peripheral surface of the rotating wheel body. Optionally, the projection of the limiting plate along the radial direction of the rotating wheel body is 2 / 5 of the outer peripheral surface of the rotating wheel body. A plurality of equally spaced mounting positions 3111 are provided on the circumferential side of the rotating wheel body, and the mounting positions 3111 are U-shaped grooves recessed inwardly of the rotating wheel body. The battery cell 1 is located between the rotating wheel body and the limiting plate, and at least part of the battery cell 1 is disposed in the U-shaped groove.

[0151] In these optional embodiments, with this arrangement, it is convenient to control the number of battery cells 1 in the battery string 2.

[0152] According to an embodiment of the present application, as Figure 4 and Figure 5As shown, the first tray 312 includes an inclined portion 3121 and two first slide rails 3122. The inclined portion 3121 is inclined in a direction away from the rotary distributor 311. The two first slide rails 3122 are fixed to the inclined portion 3121 and are spaced apart along the second direction y. The first slide rails 3122 and the inclined portion 3121 are used for sliding cooperation with the battery cells 1. The two first slide rails 3122 and the inclined portion 3121 form a receiving space for accommodating a plurality of battery cells 1. The second direction y is perpendicular to the first direction x.

[0153] In an embodiment of the present application, the two first slide rails 3122 are fixed to the inclined portion 3121. Therefore, both the two first slide rails 3122 and the inclined portion 3121 are inclined in a direction away from the rotary distributor 311. The two first slide rails 3122 and the inclined portion 3121 form an inclined chute. A plurality of battery cells 1 separated from the rotary distributor 311 slide along the chute in sequence to a predetermined position, thereby forming a battery row 2.

[0154] In these alternative embodiments, with such a setting, the battery cells 1 can slide on the inclined portion 3121 based on their own gravity, and the two first slide rails 3122 have a certain limiting effect, so that a plurality of battery cells 1 directly form a battery row 2 with a predetermined shape through the first tray 312, simplifying the manufacture of the battery row 2.

[0155] According to an embodiment of the present application, as Figures 4 to 6 shown, the first slide rail 3122 includes a first section 31221 and a second section 31222. The first section 31221 and the second section 31222 are disposed on opposite sides of the inclined portion 3121 in the thickness direction. The first section 31221 is used for sliding cooperation with the battery cell 1. The grouping mechanism 310 further includes a support member 313, a limiting member 314, a traction member 315, a guide wheel 316, and a counterweight member 317. The support member 313 is movably connected to the first section 31221. The support member 313 is configured to be driven by the gravity of the battery cell 1 to move along the first section 31221. The limiting member 314 is movably connected to the second section 31222. The guide wheel 316 is disposed on the first tray 312. One end of the traction member 315 is connected to the support member 313, and the other end of the traction member 315 bypasses the guide wheel 316 and is connected to the limiting member 314. The support member 313 drives the limiting member 314 to move along the second section 31222 through the traction member 315. The counterweight member 317 is disposed on a side of the limiting member 314 close to the guide wheel 316. The counterweight member 317 is movably connected to the second section 31222. The limiting member 314 can drive the counterweight member 317 to move along the second section 31222.

[0156] Exemplarily, the first tray 312 includes an inclined portion 3121 and two first slide rails 3122. The inclined portion 3121 has opposite first inclined surface and second inclined surface in the thickness direction. The two first slide rails 3122 are fixed to the inclined portion 3121 and are spaced apart along the second direction y. Each first slide rail 3122 includes a first section 31221 and a second section 31222. The first section 31221 is disposed on the first inclined surface, and the second section 31222 is disposed on the second inclined surface. The grouping mechanism 310 further includes a support member 313, a limiting member 314, a traction member 315, a guide wheel 316, and a counterweight member 317. The support member 313 is two first sliders 3342. The two first sliders 3342 are respectively slidably disposed on the first section 31221. The first slider 3342 is configured to drive the slider 3342 to slide along the first section 31221 by the gravity of the battery cell 1. The limiting member 314 is two second sliders 3342. The two second sliders 3342 are respectively slidably disposed on the second section 31222. The guide wheel 316 is disposed on the first tray 312. The traction member 315 is two traction ropes. One end of each traction rope is connected to the first slider 3342, and the other end of the traction member 315 bypasses the guide wheel 316 and is connected to the first slider 3342. The first slider 3342 drives the second slider 3342 to slide along the second section 31222 through the traction rope, and the sliding direction of the first slider 3342 is opposite to the sliding direction of the second slider 3342. The counterweight member 317 is a counterweight block. The counterweight block is disposed on one side of the second slider 3342 close to the guide wheel 316. The counterweight block is movably connected to the second section 31222, and the second slider 3342 can drive the counterweight block to move along the second section 31222. During the process that multiple battery cells 1 gradually disengage from the rotating wheel distributor 311, based on the gravity of the battery cells 1 themselves, the first slider 3342 is driven to slide along the top to bottom direction of the inclined portion 3121, and the first sliding through hole drives the second slider 3342 to slide from the bottom to top direction of the inclined portion 3121 through the traction rope, and the second slider 3342 drives the counterweight block to slide simultaneously.

[0157] In these optionally embodiments, it is arranged in this way to reduce the phenomenon of jamming during the sliding of the battery cell 1 along the inclined portion 3121, and it can also improve the structural consistency and unity of the formed battery unit 4.

[0158] According to an embodiment of the present application, as Figures 4 to 6 shown, in the direction away from the rotating wheel distributor 311, the dimension of the second section 31222 along the second direction y gradually increases. The grouping mechanism 310 includes multiple counterweight members 317. The multiple counterweight members 317 are spaced apart along the second section 31222, and the moving distances of each counterweight member 317 on the second section 31222 are different.

[0159] Exemplarily, in the direction away from the rotating wheel distributor 311, which can be understood as the direction from the top to the bottom of the second section 31222, the dimension of the second section 31222 along the second direction y gradually increases. The grouping mechanism 310 includes a first counterweight, a second counterweight, a third counterweight, and a fourth counterweight. Each counterweight has a sliding hole, and the sliding holes are slidably engaged with the second section 31222. Moreover, the radial dimension of the sliding hole of the first counterweight < the radial dimension of the sliding hole of the second counterweight < the radial dimension of the sliding hole of the third counterweight < the radial dimension of the sliding hole of the fourth counterweight. Therefore, the moving distances of the counterweights on the second section 31222 are different.

[0160] In these alternative embodiments, it is arranged in this way that the plurality of battery cells 1 can move uniformly on the inclined portion 3121, reducing the mutual collision between the battery cells 1 and also improving the consistency of the formation of the battery row 2.

[0161] According to an embodiment of the present application, as Figures 4 to 6 shown, the inclined portion 3121 is provided with a first through hole 31211, and in the second direction y, the dimension of the first through hole 31211 is smaller than the dimension of the battery cell 1.

[0162] In these alternative embodiments, it is arranged in this way, which is beneficial to the separation of the battery row 2 from the first tray 312.

[0163] According to an embodiment of the present application, as Figures 4 to 6 shown, the grouping mechanism 310 further includes an arc-shaped member 318. The arc-shaped member 318 is arranged between the rotating wheel distributor 311 and the first tray 312 and is connected to the inclined portion 3121. The arc-shaped member 318 is used for slidably engaging with the battery cell 1 and guiding the battery cell 1 into the accommodation space.

[0164] In these alternative embodiments, it is arranged in this way to guide the battery cell 1 into the accommodation space, facilitating the battery cell 1 separated from the rotating wheel distributor 311 to directly enter the accommodation space of the first tray 312 through the arc-shaped member 318, and also improving the stability of the conveyance of the battery cell 1.

[0165] Referring to Figures 7 to 10 , Figure 7 is a partial structural schematic diagram of the installation mechanism of the battery manufacturing device provided by some embodiments of the present application; Figure 8 is a front view of the installation mechanism of the battery manufacturing device provided by some embodiments of the present application; Figure 9 is a structural schematic diagram of the installation mechanism of the battery manufacturing device provided by some embodiments of the present application; Figure 10 is a left view of the installation mechanism of the battery manufacturing device provided by some embodiments of the present application.

[0166] According to an embodiment of the present application, as Figure 1and Figure 7 As shown in Figure 7 , the mounting mechanism 320 includes a bracket 321, a first supporting member 322, and a clamping assembly 323. The bracket 321 is disposed downstream of the grouping mechanism 310 and receives the first tray 312 having the battery rows 2 provided by the grouping mechanism 310. The first supporting member 322 is disposed on the bracket 321 and is movable relative to the bracket 321 in the third direction z. The first supporting member 322 is configured to drive the battery rows 2 to move in the third direction z and separate the battery rows 2 from the first tray 312. The clamping assembly 323 is disposed on the bracket 321. The clamping assembly 323 is configured to clamp the heat exchange plate 3 and the battery rows 2 on the first supporting member 322, and drive the battery rows 2 and the heat exchange plate 3 to flip.

[0167] In an embodiment of the present application, the mounting mechanism 320 includes a bracket 321, a first supporting member 322, and a clamping assembly 323. The bracket 321 is capable of receiving the first tray 312 having the battery rows 2 provided by the grouping mechanism 310. The first supporting member 322 is movably disposed on the bracket 321 in the third direction z. The first supporting member 322 can drive the battery rows 2 to move in the third direction z. The clamping assembly 323 is disposed on the bracket 321. The clamping assembly 323 can clamp both the heat exchange plate 3 and the battery rows 2, and can also drive the clamped heat exchange plate 3 and battery rows 2 to flip.

[0168] In an embodiment of the present application, the clamping assembly 323 is configured to clamp the heat exchange plate 3 and the battery rows 2. Specifically, the clamping assembly 323 can clamp both ends of the heat exchange plate 3 and the battery rows 2; alternatively, the clamping assembly 323 has a receiving cavity, and the heat exchange plate 3 and the battery rows 2 are clamped within the receiving cavity. The clamping assembly 323 can employ fixture clamping, cylinder clamping, hydraulic clamping, pneumatic clamping, and the like. Moreover, the clamping assembly 323 is also capable of driving the heat exchange plate 3 and the battery rows 2 to flip. The angle by which the clamping assembly 323 can drive the heat exchange plate 3 and the battery rows 2 to flip is 0 to 360°. The axis of rotation of the heat exchange plate 3 and the battery rows 2 is perpendicular to the thickness direction of the heat exchange plate 3.

[0169] Optionally, the angle by which the clamping assembly 323 can drive the heat exchange plate 3 and the battery rows 2 to flip is 180°.

[0170] Specifically, the first supporting member 322 can move along the third direction z from the initial position to the first preset position and the second preset position. In the case of the first preset position, the first supporting member 322 drives the battery row 2 away from the first tray 312. In the case of the second preset position, the heat exchange plate 3 is placed on the battery row 2, and then the heat exchange plate 3 and the battery row 2 are clamped by the clamping assembly 323. At this time, the battery row 2 is located at the bottom of the heat exchange plate 3 along the third direction z. Then, the first supporting member 322 moves in the direction of the initial position, and the clamping assembly 323 drives the heat exchange plate 3 and the battery row 2 to flip, so that the battery row 2 is located at the top of the heat exchange plate 3 along the third direction z. When the bracket 321 receives the next first tray 312 having the battery row 2, the first supporting member 322 moves from the initial position to the first preset position. In the case of the first preset position, the first supporting member 322 drives the next battery row 2 away from the first tray 312. In the case of the second preset position, the clamping assembly 323 releases the flipped heat exchange plate 3 and battery row 2, so that the battery row 2, the heat exchange plate 3 and the battery row 2 are stacked to realize the assembly of the battery unit 4.

[0171] Specifically, adhesive is provided on both sides of the heat exchange plate 3, and the heat exchange plate 3 is bonded to the battery rows 2 on both sides through the adhesive.

[0172] In these alternative embodiments, it is arranged in this way to simplify the assembly of the battery unit 4 and reduce the manufacturing cost of the installation mechanism 320.

[0173] According to an embodiment of the present application, as Figures 8 to 10 shown, the clamping assembly 323 includes a first clamping assembly 323a and a second clamping assembly 323b. The first clamping assembly 323a and the second clamping assembly 323b are movably connected to the bracket 321 along the fourth direction g. The first clamping assembly 323a and the second clamping assembly 323b are respectively used to clamp the two ends of the battery row 2 and the heat exchange plate 3, and drive the battery row 2 and the heat exchange plate 3 to flip. The fourth direction g is perpendicular to the third direction z.

[0174] In the embodiment of the present application, the clamping assembly 323 includes a first clamping assembly 323a and a second clamping assembly 323b. The first clamping assembly 323a and the second clamping assembly 323b are movably connected to the bracket 321 along the fourth direction g. The first clamping assembly 323a and the second clamping assembly 323b are arranged at intervals along the fourth direction g. The battery row 2 and the heat exchange plate 3 are located between the first clamping assembly 323a and the second clamping assembly 323b. The first clamping assembly 323a and the second clamping assembly 323b respectively clamp the two ends of the battery row 2 and the heat exchange plate 3. The fourth direction g is perpendicular to the third direction z.

[0175] Exemplarily, the battery box body has a rectangular structure with a predetermined length and width. The fourth direction g is parallel to the width direction. The first clamping assembly 323a and the second clamping assembly 323b are arranged at intervals along the width direction. The first clamping assembly 323a and the second clamping assembly 323b clamp the two ends of the battery row 2 and the heat exchange plate 3 in the width direction.

[0176] In an embodiment of the present application, the first clamping assembly 323a and the second clamping assembly 323b clamp the two ends of the battery row 2 and the heat exchange plate 3. The structures of the first clamping assembly 323a and the second clamping assembly 323b may be the same, or the structures of the first clamping assembly 323a and the second clamping assembly 323b are arranged in a mirror image.

[0177] In these alternative embodiments, by setting like this, the installation stability between the clamping assembly 323 and the battery row 2 and the heat exchange plate 3 can be improved, the risk that the clamping assembly 323 drives the battery row 2 and the heat exchange plate 3 to turn over and fall off can be effectively reduced, and the overall structure of the clamping assembly 323 can also be simplified.

[0178] According to an embodiment of the present application, as Figures 8 to 10 shown, the first clamping assembly 323a includes a rotating member 3231, a clamping beam 3232, and a pressing member 3233. The rotating member 3231 is rotatably arranged on the bracket 321. The clamping beam 3232 is connected to the rotating member 3231, and the rotating member 3231 can drive the clamping beam 3232 to rotate. The pressing member 3233 is installed on the clamping beam 3232. The pressing member 3233 and the clamping beam 3232 form a first guiding groove 3234 extending along the fifth direction m. The first guiding groove 3234 is used to accommodate at least part of the battery cell 1 and the heat exchange plate 3. The pressing member 3233 is used to press the battery cell 1 and the heat exchange plate 3. The fifth direction m is perpendicular to the third direction z and the fourth direction g.

[0179] In an embodiment of the present application, the rotating member 3231 is arranged on the bracket 321, and the rotating member 3231 can rotate relative to the bracket 321. Specifically, the rotating member 3231 may include a ring, a gear, a rotating shaft, etc. The first clamping assembly 323a further includes a third driving member, and the rotating member 3231 can be driven by the third driving member to drive the clamping beam 3232 and the pressing member 3233 to rotate synchronously.

[0180] In an embodiment of the present application, the pressing member 3233 and the clamping beam 3232 form a first guiding groove 3234 extending along the fifth direction m. The first guiding groove 3234 is used to accommodate at least part of the battery cell 1 and the heat exchange plate 3. It can be understood that the clamping beam 3232 includes side walls and a bottom wall connecting the side walls. The pressing member 3233 is connected to one end of the side wall away from the bottom wall. Thus, the side wall, the bottom wall, and the pressing member 3233 form the first guiding groove 3234 extending along the fifth direction m. The first guiding groove 3234 has an opening along the fourth direction g, and the battery cell 1 and the heat exchange plate 3 are accommodated in the first guiding groove 3234 through the opening. After the battery cell 1 and the heat exchange plate 3 are in a predetermined position, the pressing member 3233 presses the clamping beam 3232 to achieve the installation and positioning of the battery cell 1 and the heat exchange plate 3.

[0181] Specifically, the structure of the second clamping assembly 323b is the same as that of the first clamping assembly 323a, so that when the battery cell 1 and the heat exchange plate 3 are clamped by the clamping assembly 323, one end of the battery cell 1 and the heat exchange plate 3 is in the first guiding groove 3234 of the first clamping assembly 323a, and the other end of the battery cell 1 and the heat exchange plate 3 is in the first guiding groove 3234 of the second clamping assembly 323b.

[0182] In an embodiment of the present application, the pressing member 3233 is connected to the clamping beam 3232, and the pressing member 3233 can press the battery cell 1 and the heat exchange plate 3 to achieve the positioning of the battery cell 1 and the heat exchange plate 3. Specifically, the pressing member 3233 includes a screw, an elastic member, a cylinder, a clamping plate, etc.

[0183] In these alternative embodiments, with such a setting, on the one hand, at least part of the battery cell 1 and the heat exchange plate 3 are accommodated in the first guiding groove 3234, so as to form an interference fit with the first guiding groove 3234 to achieve the connection between the first clamping assembly 323a and the battery cell 1 and the heat exchange plate 3, and it is not easy to fall off during rotation; on the other hand, the setting of the pressing member 3233 is used to achieve the positioning cooperation between the first clamping assembly 323a and the battery cell 1 and the heat exchange plate 3, so as to reduce the risk of the battery cell 1 and the heat exchange plate 3 falling off from the clamping assembly 323.

[0184] According to an embodiment of the present application, as Figures 8 to 10 shown, the pressing member 3233 is movably connected to the clamping beam 3232 along the third direction z.

[0185] In an embodiment of the present application, during the relative movement of the battery cell 1 and the heat exchange plate 3 with respect to the clamping beam 3232, the pressing member 3233 does not move. When the battery cell 1 and the heat exchange plate 3 reach a predetermined position, the pressing member 3233 moves in the direction close to the battery cell 1 and the heat exchange plate 3 along the third direction z, so as to press the battery cell 1 and the heat exchange plate 3, thereby limiting the battery cell 1 and the heat exchange plate 3.

[0186] In these optional embodiments, such a configuration can more accurately adjust the pressing member 3233 so that the first clamping assembly 323a stably clamps the battery cell 1 and the heat exchange plate 3 without causing damage to the battery cell 1 and the heat exchange plate 3.

[0187] According to one embodiment of the present application, Figures 8 to 10 As shown, the installation mechanism 320 also includes a grabbing member 3235, which is movably connected to the bracket 321 along the third direction z, and the grabbing member 3235 and the first supporting member 322 are arranged along the third direction z. The grabbing member 3235 is used to assemble the battery column 2 and the heat exchange plate 3 flipped by the clamping assembly 323 with the battery column 2 on the first supporting member 322 to form a battery unit 4.

[0188] In the embodiment of the present application, the mounting mechanism 320 further includes a grabbing member 3235, which is movably connected to the bracket 321 along the third direction z, and the grabbing member 3235 and the first supporting member 322 are arranged along the third direction z. The clamping assembly 323 releases the flipped battery array 2 and the heat exchange plate 3, and the grabbing member 3235 can drive the battery array 2 and the heat exchange plate 3 to the battery array 2 on the first supporting member 322 to realize the assembly of the battery unit 4. In addition, the grabbing member 3235 can also be used to grab the battery array 2 on the first supporting member 322.

[0189] Exemplarily, the first supporting member 322 moves from the initial position along the third direction z. When the first supporting member 322 moves to the first preset position, the first supporting member 322 drives the battery array 2 to separate from the first tray 312. When the first supporting member 322 moves to the second preset position, the heat exchange plate 3 is placed on the battery array 2 and the heat exchange plate 3 is bonded to the battery array 2. At this time, the battery array 2 is located at the bottom of the heat exchange plate 3. The gripping member 3235 grips the heat exchange plate 3. The first supporting member 322 moves to the initial position to separate the heat exchange plate 3 and the battery array 2 from the first supporting member 322. The heat exchange plate 3 and the battery array 2 are then clamped by the clamping assembly 323. The gripping member 3235 releases the heat exchange plate 3. The holding component 323 drives the heat exchange plate 3 and the battery column 2 to flip 180°, and then the grasping member 3235 grasps the flipped battery column 2. At this time, the battery column 2 is located on the top of the heat exchange plate 3. The clamping component 323 releases the flipped heat exchange plate 3 and the battery column 2, and the first supporting member 322 moves from the initial position to the first preset position. The first supporting member 322 drives another battery column 2 to detach from the first tray 312. When the first supporting member 322 drives another battery column 2 to continue to move to the second preset position, the grasping member 3235 grasps the battery column 2 and the heat exchange plate 3 and installs them on the top of another battery column 2, so that the battery column 2, the heat exchange plate 3 and the battery column 2 are stacked to realize the assembly of the battery unit 4.

[0190] Specifically, the grabbing member 3235 includes a sponge suction cup and a connecting rod, and the sponge suction cup is used to connect with the heat exchange plate 3 or the battery array 2.

[0191] In these optional embodiments, such a configuration facilitates the assembly of the battery cells 4 to improve the structural consistency of the battery cells 4 .

[0192] Combined with reference Figures 11 to 13 , Figure 11 A front view of a film laying mechanism of a battery manufacturing device provided in some embodiments of the present application; Figure 12 A schematic diagram of the structure of a film laying mechanism of a battery manufacturing device provided in some embodiments of the present application; Figure 13 A schematic structural diagram from another angle of the film laying mechanism of the battery manufacturing device provided in some embodiments of the present application.

[0193] According to one embodiment of the present application, Figures 11 to 13 The film laying mechanism 330 includes a frame 331, a mold 332, a reeling assembly 333 and a rolling mechanism 334. The mold 332 is disposed on the frame 331. The reeling assembly 333 is disposed on the frame 331, and is used to release the protective film 5 and attach the protective film 5 to the mold 332. The rolling mechanism 334 is used to cooperate with the mold 332 to roll the protective film 5 into a structure that cooperates with the battery array 2.

[0194] In an embodiment of the present application, the film laying mechanism 330 includes a frame 331, a mold 332, a reeling assembly 333 and a rolling mechanism 334 to attach the protective film 5 to the battery cell 4, specifically, the protective film 5 is attached to the side of the battery column 2 away from the heat exchange plate 3.

[0195] The frame 331 serves as a basic component of the film laying mechanism 330 and is used to install and carry other components, such as a mold 332 , an unwinding assembly 333 and a rolling mechanism 334 .

[0196] The mold 332 is disposed on the frame 331 and is used to receive the protective film 5 released by the unwinding assembly 333. Specifically, the mold 332 has a pressing surface, and the protective film 5 released by the unwinding assembly 333 is attached to the pressing surface. Optionally, the battery cell 1 is a cylindrical battery cell 1, and the pressing surface has a wave structure that matches the battery column 2.

[0197] The unwinding assembly 333 is disposed on the frame 331, and is used to release the protective film 5 and attach the protective film 5 to the mold 332. Specifically, the unwinding assembly 333 moves at least partially along the extension direction of the pressing surface to drive at least part of the protective film 5 to move, thereby releasing the protective film 5 of corresponding size according to the size of the battery cell 1.

[0198] The rolling mechanism 334 is used to cooperate with the mold 332 to roll the protective film 5 into a structure that cooperates with the battery row 2. It can be understood that the protective film 5 specifically has a first surface and a second surface facing away from each other. The first surface contacts the mold 332, and the second surface contacts the rolling mechanism 334.

[0199] Specifically, the rolling mechanism 334 includes a pressure roller. The pressure roller is rotatably arranged on the pressing surface of the mold 332 and cooperates with the pressure roller to roll the protective film 5.

[0200] Optionally, the pressure roller adopts a flat roller, that is, the surface of the pressure roller for rolling the protective film 5 is in an arc tooth shape, and the arc teeth cooperate with the wavy pressing surface.

[0201] In these alternative embodiments, applying the film laying mechanism 330 to the battery manufacturing device 1000 can improve the forming effect of the protective film 5, and further improve the overall forming effect of the battery unit 4.

[0202] According to an embodiment of the present application, the mold 332 has a vacuum passage, and the opening of the vacuum passage is used to face the protective film 5.

[0203] Optionally, the vacuum passage has a porous opening, and a plurality of openings are arranged at intervals along the extending direction of the mold 332.

[0204] In these alternative embodiments, the mold 332 is provided with a vacuum passage for communicating with an external negative pressure mechanism. The opening of the vacuum passage faces the protective film 5. After the rolling mechanism 334 and the mold 332 cooperate to extrude the mold 332, the negative pressure mechanism evacuates the protective film 5 through the air flow passage, so that a negative pressure is formed between the protective film 5 and the mold 332, so that the protective film 5 is tightly attached to the mold 332 to improve the forming effect of the protective film 5.

[0205] According to an embodiment of the present application, as Figures 11 to 13 , the unwinding assembly 333 includes a support base 3331, an unwinding part 3332, and a moving part 3333. The support base 3331 is arranged on the frame 331. The unwinding part 3332 is arranged on the support base 3331, and the protective film 5 is movably arranged on the unwinding part 3332. The moving part 3333 can drive the protective film 5 to move along the extending direction of the mold 332 and attach the protective film 5 to the mold 332.

[0206] In an embodiment of the present application, the unwinding part 3332 is arranged on the support base 3331, and the protective film 5 is movably arranged on the unwinding part 3332. Specifically, the unwinding part 3332 is a rotatable roller, and the protective film 5 is sleeved on the roller and rotates along the axial direction of the roller. During the rotation of the roller, the protective film 5 is released. The moving part 3333 can drive the protective film 5 to move along the extending direction of the mold 332. During the movement of the protective film 5, the protective film 5 pulls the roller to rotate and release more protective film 5. When the predetermined size of the released protective film 5 is reached, the protective film 5 is attached to the mold 332.

[0207] In an embodiment of the present application, the moving part 3333 can drive the protective film 5 to move along the extending direction of the mold 332 and attach the protective film 5 to the mold 332. It can be understood that the moving part 3333 drives the protective film 5 to move, so that the protective film 5 is released to the predetermined size, and the protective film 5 can be manually attached to the mold 332, or the moving part 3333 can be adjusted to move towards the mold 332 to attach the protective film 5 to the mold 332.

[0208] In some embodiments, the mold 332 further includes a pressure plate and a fifth driving member. After the protective film 5 is attached to the pressing surface of the mold 332, the fifth driving member drives the pressure plate to position the protective film 5, so as to prevent the protective film 5 from moving during the rolling of the rolling mechanism 334 on the protective film 5, resulting in a mismatch between the extruded protective film 5 and the structure of the battery row 2.

[0209] In these alternative embodiments, such a setting can enable the protective film 5 to be stably attached to the mold 332 to achieve a better forming effect.

[0210] According to an embodiment of the present application, as Figures 11 to 13 , the moving part 3333 includes a second slide rail 33331 and a moving member 33332. The second slide rail 33331 extends along the extending direction, and the moving member 33332 can drive the protective film 5 to slide along the second slide rail 33331.

[0211] Specifically, the moving part 3333 includes two second slide rails 33331 and two moving members 33332. Each moving member 33332 is slidably connected to its corresponding second slide rail 33331. The two second slide rails 33331 are located on both sides of the mold 332 and extend along the extending direction of the mold 332. The two moving members 33332 can clamp both ends of the protective film 5 and drive the protective film 5 to move along the extending direction.

[0212] In these alternative embodiments, the setting of the second slide rail 33331 can plan the moving path of the protective film 5 to stably lay the protective film 5 on the mold 332.

[0213] According to an embodiment of the present application, the unwinding assembly 333 further includes a cutting part 3334, which is arranged on the support seat 3331, and the cutting mechanism is used to cut the protective film 5.

[0214] In the implementation of the present application, the cutting part 3334 is arranged on the support seat 3331 and is located between the unwinding part 3332 and the moving part 3333. The unwinding part 3332 releases the protective film 5, and the moving part 3333 drives the protective film 5 to move. After moving to a predetermined position, the cutting part 3334 cuts the protective film 5 and then attaches the protective film 5 to the mold 332.

[0215] According to an embodiment of the present application, as Figures 11 to 13 , the rolling mechanism 334 includes a third slide rail 3341, a slider 3342 and a pressing wheel 3343. The third slide rail 3341 is arranged on the support seat 3331 and extends along the extending direction. The slider 3342 is slidably connected to the third slide rail 3341. The pressing wheel 3343 is arranged on the slider 3342, and the pressing wheel 3343 can rotate relative to the slider 3342. The pressing wheel 3343 cooperates with the mold 332 to roll the protective film 5.

[0216] Specifically, the rolling mechanism 334 includes two third slide rails 3341, two sliders 3342 and a pressing wheel 3343. The third slide rail 3341 is arranged on the support seat 3331 and extends along the extending direction, and the two third slide rails 3341 are arranged on both sides of the mold 332. Each slider 3342 is slidably connected to the corresponding third slide rail 3341, and the pressing wheel 3343 is located between the two sliders 3342 and is rotatably connected to the two sliders 3342.

[0217] Optionally, the rolling mechanism 334 further includes a cylinder, and the cylinder drives the slider 3342 to drive the pressing wheel 3343 to move along the third slide rail 3341.

[0218] In these optional embodiments, with such a setting, it can not only simplify the overall structure of the rolling mechanism 334, but also realize the reciprocating rolling of the pressing wheel 3343 on the protective film 5 to improve the forming effect of the protective film 5.

[0219] With reference to Figure 14 and Figure 15 , Figure 14 is a schematic structural diagram of the transmission mechanism of the battery manufacturing device provided by some embodiments of the present application; Figure 15 is a partial structural schematic diagram of the transmission mechanism of the battery manufacturing device provided by some embodiments of the present application.

[0220] According to an embodiment of the present application, as Figure 2 , Figure 14 and Figure 15As shown, the transmission mechanism 200 includes a conveying assembly 220 and a plurality of flexible conveying pipelines 230. The conveying assembly 220 is arranged downstream of the feeding mechanism 100 and is used to receive a plurality of battery cells 1 provided by the feeding mechanism 100. The plurality of flexible conveying pipelines 230 are arranged at one end of the conveying assembly 220 away from the feeding mechanism 100. Each flexible conveying pipeline 230 is connected to the conveying assembly 220 and each first assembly mechanism 300, and each flexible conveying pipeline 230 and the conveying assembly 220 form a transmission channel 210. At least a part of each flexible conveying pipeline 230 is twisted relative to the conveying assembly 220 to rotate the battery cell 1 conveyed through the flexible conveying pipeline 230 by 90°.

[0221] In an embodiment of the present application, the conveying assembly 220 is arranged downstream of the feeding mechanism 100, and is used to receive a plurality of battery cells 1 provided by the feeding mechanism 100 and convey the plurality of battery cells 1 to the plurality of flexible conveying pipelines 230.

[0222] Specifically, the conveying assembly 220 includes a conveyor belt, and the conveyor belt conveys along the horizontal direction.

[0223] In an embodiment of the present application, the plurality of flexible conveying pipelines 230 are arranged at one end of the conveying assembly 220 away from the feeding mechanism 100. The plurality of flexible conveying pipelines 230 are arranged in parallel. Each flexible conveying pipeline 230 is connected to the conveying assembly 220 and each first assembly mechanism 300, and each flexible conveying pipeline 230 and the conveying assembly 220 form a transmission channel 210. It can be understood that the plurality of flexible conveying pipelines 230 and the conveying assembly 220 form a plurality of transmission channels 210. At least a part of each flexible conveying pipeline 230 is twisted relative to the conveying assembly 220.

[0224] Specifically, the flexible conveying pipeline 230 includes a first pipeline and a second pipeline. The first pipeline is communicated with the second pipeline and the conveying assembly 220. The transmission direction of the first pipeline is the same as the transmission direction of the conveying assembly 220. The second pipeline is communicated with the first assembly mechanism 300. The input end of the second pipeline is connected to the first pipeline, the output end is twisted by 90° and connected to the first assembly mechanism 300. The second pipeline is twisted by 90° relative to the first pipeline. The output end of the second pipeline conveys along the vertical direction to rotate the battery cell 1 conveyed through the flexible conveying pipeline 230 by 90°.

[0225] Exemplarily, the flexible conveying pipeline 230 includes a bottom wall and two side walls connecting opposite sides of the bottom wall. The pipeline formed by enclosing the bottom wall and the two side walls is used to convey the battery cell 1.

[0226] In these alternative embodiments, a plurality of flexible conveying pipelines 230 are arranged in parallel, enabling the assembly of multiple battery cells 4 simultaneously. In addition, the arrangement of the flexible conveying pipeline 230 can realize the rotation of the battery monomer 1 while conveying it, facilitating its entry into the first assembly mechanism 300, thereby simplifying the overall transmission mode of the battery monomer 1.

[0227] According to an embodiment of the present application, as Figure 14 and Figure 15 shown, the conveying assembly 220 includes a first conveyor belt 221, two second conveyor belts 222, and two partition plates 223. The first conveyor belt 221 is connected to the flexible conveying pipeline 230 and the feeding mechanism 100. The two second conveyor belts 222 are arranged on both sides of the first conveyor belt 221 along the sixth direction n. The conveying direction of the first conveyor belt 221 is opposite to that of the second conveyor belt 222. The partition plate 223 is arranged on the second conveyor belt 222, and the partition plate 223 is used to prevent the battery monomer 1 from falling off. The sixth direction n is perpendicular to the conveying direction.

[0228] In the embodiment of the present application, the conveying assembly 220 includes a first conveyor belt 221, two second conveyor belts 222, and two partition plates 223. The first conveyor belt 221 is connected to the flexible conveying pipeline 230 and the feeding mechanism 100. The conveying direction of the first conveyor belt 221 is the main conveying direction. It can be understood that the battery monomer 1 transports multiple battery monomers 1 provided by the feeding mechanism 100 to the multiple flexible conveying pipelines 230 through the first conveyor belt 221. The two second conveyor belts 222 are arranged on both sides of the first conveyor belt 221 along the sixth direction n. The sixth direction n is perpendicular to the conveying direction, and the conveying direction of the first conveyor belt 221 is opposite to that of the second conveyor belt 222. The partition plate 223 is arranged on the second conveyor belt 222.

[0229] In the initial state when the conveying assembly 220 is working, multiple battery monomers 1 are transported to the multiple flexible conveying pipelines 230 through the first conveyor belt 221. As more and more battery monomers 1 are provided by the feeding mechanism 100, the battery monomers 1 that have not been transported to the flexible conveying pipeline 230 stay on the side of the first conveyor belt 221 close to the flexible conveying pipeline 230. The battery monomers 1 collide with each other and move towards the second conveyor belts 222 on both sides. The second conveyor belts 222 drive the battery monomers 1 to move away from the flexible conveying pipeline 230 to relieve the aggregation of the battery monomers 1 and affect the normal transmission of the battery monomers 1.

[0230] Optionally, the partition plate 223 includes a straight section and an arc section connecting both ends of the straight section. One arc section is connected to the flexible conveying pipeline 230, and the other arc section extends towards the first conveyor belt 221.

[0231] In these alternative embodiments, it is arranged in such a way that the conveying efficiency of the battery cell 4 can be improved.

[0232] According to an embodiment of the present application, the length of the first conveyor belt 221 is greater than the length of the second conveyor belt 222, and the second conveyor belt 222 is located at one end of the first conveyor belt close to the flexible conveying pipeline 230.

[0233] According to an embodiment of the present application, as Figure 14 and Figure 15 shown, the first conveyor belt 221 includes a first sub-belt 2211 and a plurality of second sub-belts 2212. The plurality of second sub-belts 2212 are arranged on both sides of the first sub-belt 2211 and are located between the first sub-belt 2211 and the second conveyor belt 222. Both the first sub-belt 2211 and the second sub-belts 2212 are communicated with the feeding mechanism 100. The conveying assembly 220 further includes a guiding plate 224, which is arranged at one end of the first sub-belt 2211 close to the flexible conveying pipeline 230. Both ends of the guiding plate 224 extend towards the second sub-belts 2212 located on both sides of the first sub-belt 2211.

[0239] According to an embodiment of the present application, as Figure 16 shown, the second assembling mechanism 400 includes a base 410 and a plurality of assembling components 420. The plurality of assembling components 420 are oppositely arranged along the seventh direction p. Each assembling component 420 drives the battery unit 4 to move along the seventh direction p to assemble a plurality of battery units 4 into a battery pack 6, and a protective film 5 is provided between two adjacent battery units 4 in the battery pack 6.

[0240] In an embodiment of the present application, the second assembling mechanism 400 includes a base 410 and a plurality of assembling components 420. The number of the assembling components 420 is based on the number of the battery units 4 in the battery pack 6. It can be understood that one assembling component 420 supports one battery unit 4. When the battery pack 6 includes two battery units 4, the second assembling mechanism 400 includes two assembling components 420. When the battery pack 6 includes three battery units 4, the second assembling mechanism 400 includes three assembling components 420.

[0241] In an embodiment of the present application, the plurality of assembling components 420 are oppositely arranged along the seventh direction p. Each assembling component 420 drives the battery unit 4 to move along the seventh direction p and makes the plurality of battery units 4 approach each other, and the plurality of battery units 4 are assembled into a battery pack 6 through the protective film 5.

[0242] Specifically, the assembling component 420 can adopt a clamping hand, a pushing member, etc. to drive each battery cell 1 to approach each other.

[0243] In these alternative embodiments, a plurality of battery cells 4 are assembled into a battery pack 6 by a plurality of assembly components 420, and each assembly component 420 can be controlled individually, which is conducive to assembling the battery pack 6.

[0244] According to an embodiment of the present application, as Figures 17 to 21 shown, the assembly component 420 includes a rotating plate 421, a movable plate 422, a first driving member 423, and a second driving member 424. The rotating plate 421 is rotatably disposed on the base 410. The movable plate 422 is movably connected to the rotating plate 421 and forms a second guiding groove extending along the eighth direction q with the rotating plate 421. The second guiding groove is used to accommodate at least a part of the battery cell 4, and the eighth direction q is perpendicular to the seventh direction p. The first driving member 423 is connected to the rotating plate 421, and the first driving member 423 drives the battery cell 4 to rotate through the rotating plate 421 so that the battery cells 4 are relatively disposed along the seventh direction p. The second driving member 424 is connected to the movable plate 422, and the second driving member 424 clamps the battery pack 6 through the movable plate 422.

[0245] Exemplarily, the second assembly mechanism 400 includes a base 410 and two assembly components 420. Each assembly component 420 includes a rotating plate 421, a movable plate 422, a first driving member 423, and a second driving member 424. The two assembly components 420 include a first assembly component and a second assembly component. The first assembly component carries the battery cell 1, and the second assembly component carries the battery cell 1 with the protective film 5. Specifically, first, the battery cell 1 with the protective film 5 is accommodated in the second guiding groove formed by the movable plate 422 and the rotating plate 421 of the second assembly component, and the battery cell 1 is accommodated in the second guiding groove formed by the movable plate 422 and the rotating plate 421 of the first assembly component. Then, through the driving of the first driving member, the movable plate 422 and the rotating plate 421 drive the battery cell 4 to rotate, so that the first assembly component drives the battery cell 4 to rotate 180°, and the second assembly component drives the battery cell 4 with the protective film 5 to rotate 180°. With such a setting, on the one hand, before the first driving member 423 drives the rotating plate 421 to rotate, the protective film 5 is located outside the second guiding groove and does not contact the movable plate 422 and the rotating plate 421. After the rotating plate 421 is driven to rotate by the first driving member, the battery cell 4 rotates 180°, so that the protective film 5 is located between the two battery cells 1. The first assembly component drives the battery cell 4 and the second assembly component drives the battery cell 4 with the protective film 5 to approach each other along the seventh direction p, so that the two battery cells 4 are bonded together through the protective film 5 to form the battery pack 6. The first assembly component and the second assembly component move away from each other to release the battery pack 6. In order to reduce the movement of the battery pack 6 with the first assembly component or the second assembly component. The second driving member 424 can drive the movable plate 422 to move relative to the rotating plate 421 along the seventh direction p to clamp the battery pack 6.

[0246] In these alternative embodiments, the battery cell 4 is disposed in the second guiding groove formed by the movable plate 422 and the rotating plate 421, and is driven by the first driving member 423 to rotate the battery cell 4, reducing the influence of the movable plate 422 and the rotating plate 421 on the protective film 5. It is driven by the second driving member 424 to stably clamp the battery pack 6, improving the stability of the formation of the battery pack 6.

[0247] According to an embodiment of the present application, as Figure 17 and Figure 20 shown, the second assembling mechanism 400 further includes a lifting frame 425 and a second tray 426. The lifting frame 425 is movably disposed on the base 410 along the ninth direction r. The second tray 426 is detachably connected to the lifting frame 425. The second tray 426 is used to support the battery pack 6. The lifting frame 425 drives the battery pack 6 to move along the ninth direction r through the second tray 426. The ninth direction r is perpendicular to the seventh direction p and the eighth direction q.

[0248] In the embodiment of the present application, after the movable plate 422 clamps the battery pack 6, the lifting frame 425 drives the second tray 426 to move close to the battery pack 6 along the ninth direction r to a predetermined position. This predetermined position is where the second tray 426 abuts against the battery pack 6 and can carry the battery pack 6. When the second driving member 424 drives the movable plate 422 to move to the maximum distance along the seventh direction p, the assembling components 420 continue to move away from each other, the movable plate 422 releases the battery pack 6, and the lifting frame 425 drives the battery pack 6 to move along the ninth direction r through the second tray 426.

[0249] In these alternative embodiments, by providing the lifting frame 425 and the second tray 426, the battery pack 6 released from the assembling components 420 is carried and driven to the target position.

[0250] According to an embodiment of the present application, the assembling mechanism further includes a third conveyor belt 427, and the third conveyor belt 427 can convey the second tray 426 and the battery pack 6 detached from the lifting frame 425.

[0251] In these alternative embodiments, the lifting frame 425 drives the battery pack 6 to move along the ninth direction r through the second tray 426. After moving to the target position, the second tray 426 is separated from the lifting frame 425, and the second tray 426 drives the battery pack 6 to be transported on the third conveyor belt 427 for transportation to the next process operation.

[0261] The pallet assembly 110 is used to carry the battery cell 1. The pallet assembly 110 includes a plurality of third pallets 10 stacked in a eleventh direction t. Two adjacent third pallets 10 are plugged into each other in the eleventh direction t to fix the installation of each third pallet 10. Each third pallet 10 has a receiving space for receiving a battery cell 1. Specifically, first, the battery cell 1 is installed in the receiving space of one third pallet 10, and then another third pallet 10 is plugged into the third pallet 10 having the battery cell 1. In this way, each third pallet 10 has a battery cell 1.

[0267] Two adjacent third trays 10 are plugged into each other. Specifically, the two third trays 10 can be plugged into each other through their own structural designs, or the two third trays 10 can be plugged into each other through connecting members. The plug-in connection between two adjacent third trays 10 facilitates the installation and disassembly between the third trays 10 and improves the assembly efficiency between the third trays 10.

[0268] In these alternative embodiments, the tray assembly 110 includes a plurality of third trays 10 which are stacked along the eleventh direction t. At least one end of each third tray 10 along the tenth direction s is provided with a port 11. The battery cell 1 placed on each third tray 10 can move on the third tray 10 and be transferred and loaded through the port 11, without the need to use a lifting member for grasping, which is convenient and fast in operation, improves the transfer speed of the battery cell 1, and can also achieve the effect of batch loading of the battery cell 1.

[0269] According to an embodiment of the present application, both ends of the third tray 10 along the tenth direction s are provided with ports 11.

[0270] In an embodiment of the present application, both ends of the third tray 10 along the tenth direction s are provided with ports 11. The two ports 11 include a first port and a second port. A battery cell 1 is provided in the accommodation space of the third tray 10. A pushing member can be inserted into the accommodation space through the first port and push the battery cell 1 to move along the tenth direction s, so as to transfer the battery cell 1 from the second port to other carrier members.

[0271] In some embodiments, the two ports 11 include a first port and a second port. The second port can be used as a discharge port for transferring the battery cell 1 to other downstream carrier members, and the first port can be used as a loading port for receiving the battery cell 1 from upstream.

[0272] In these alternative embodiments, it is arranged in such a way that it is convenient to apply a force to the battery cell 1 to drive the battery cell 1 arranged in the accommodation space to be transported from the port 11.
