a tray storage rack 220 configured to store empty trays 2131, provided on one side of the storage bin 210 in the transverse direction H;

a carrying mechanism 230 including a suction cup 231 and a frame 232 suspended across both sides of the storage bin 210 in the lateral direction H, the suction cup 231 being movably connected to the frame 232 in the lateral direction H, and the suction cup 231 being configured to suck a battery cover plate BP or an empty tray 2131;

wherein the longitudinal direction Z, the height direction G and the transverse direction H are mutually perpendicular.

During the operation of the transfer device 200, firstly, the suction cup 231 on the carrying mechanism 230 adsorbs the battery cover plate BP on the tray 2131 in the storage cavity 2111 through negative pressure, then the suction cup 231 which adsorbs the battery cover plate BP moves to a designated station on one side away from the storage bin 210 along the transverse direction H on the frame 232, then the battery cover plate BP is placed at the designated station by the suction cup 231, then the suction cup 231 moves to the position of the tray module 213 along the transverse direction H of the frame 232, the empty tray 2131 is adsorbed again through negative pressure, the suction cup 231 which adsorbs the empty tray 2131 moves to one side of the storage bin 210 along the transverse direction H, and the empty tray 2131 is placed on the tray storage rack 220, and finally the suction cup 231 moves to the tray module 213 to repeatedly transfer the battery cover plate BP or the empty tray 2131; the transfer device 200 can greatly improve the feeding efficiency of the battery cover plate BP, can prevent the battery cover plate BP from being scratched, and is convenient to operate and high in reliability.

In one example of the present invention, further comprising: the first lifting mechanism 240 is provided with a first lifting mechanism,

the first lifting mechanism 240 is disposed at the lower end of the storage bin 210 and configured to lift the tray module 213 by the height of one layer of trays 2131 after the top layer of trays 2131 are conveyed by the conveying mechanism 230;

after the upper tray 2131 is carried by the carrying mechanism 230, a gap is formed between the suction cup 231 and the lower battery cover plate BP, so that the suction cup 231 can not effectively contact with the battery cover plate BP and adsorb the battery cover plate BP, so that the suction cup 231 can continuously and effectively adsorb the battery cover plate BP on the lower tray 2131, and the tray module 213 is lifted by the first lifting mechanism 240 to the height of the upper tray 2131, thereby solving the above problem.

Preferably, the first lifting mechanism 240 may be one of a cylinder, an electric push rod and a hydraulic cylinder.

In one example of the present invention, the first elevating mechanism 240 further includes:

a lifting plate 241 installed on the first lifting mechanism 240 and configured to be lifted in synchronization with the first lifting mechanism 240 to support the tray 2131;

for example, the first lifting mechanism 240 includes a cylinder and a piston rod that is retractable in the cylinder, and the lifting plate 241 is fixedly connected to the piston rod.

The contact area between the first lifting mechanism 240 and the tray module 213 can be increased by arranging the lifting plate 241, so that the stability and reliability of the first lifting mechanism 240 lifting the tray module 213 are improved.

In one example of the present invention, further comprising: the transfer mechanism 250 is configured to transfer the fluid,

arranged along the longitudinal direction Z of the storage bin 210, configured to drive one of the tray modules 213 to move to a previously empty position along the longitudinal direction Z when the empty position is formed after the other tray module 213 is completely carried by the carrying mechanism 230;

because the tray modules 213 are stacked layer by the multi-layer tray 2131, the tray modules 213 can be moved in the longitudinal direction Z by the arrangement of the conveying mechanism 250, i.e. after the previous tray module 213 is conveyed by the conveying mechanism 230, the conveying mechanism 250 conveys the next tray module 213 to the position of the previous tray module 213, so that the conveying mechanism 230 can continuously convey the battery cover plate BP and the empty tray 2131, and the conveying efficiency of the conveying device 200 is greatly improved.

In one example of the present invention, the transfer mechanism 250 includes:

a first moving module 251 including a first rail portion 2511, a first sliding portion 2512 and a first driving portion 2513;

the first rail portion 2511 is disposed along a longitudinal direction Z, the first sliding portion 2512 is movably disposed on the first rail portion 2511, and the first driving portion 2513 is configured to drive the first sliding portion 2512 to reciprocate on the first rail portion 2511;

a first lifting module 252 connected to the first sliding portion 2512 and configured to be capable of switching movement between a lifting position for lifting the tray module 213 and a release position for releasing the tray module 213;

for example, in the conveying mechanism 250, the first moving module 251 is a screw-and-screw mechanism, that is, a screw is pivotably disposed in the first guide rail portion 2511, an output end of the first driving portion 2513 (for example, a motor) is connected to the screw, the first sliding portion 2512 is connected to the screw through a screw thread, and during the forward and reverse driving of the screw by the first driving portion 2513, the first sliding portion 2512 reciprocates along the first guide rail, so as to realize the movement of the first moving module 251 in the longitudinal direction Z; in addition, since the first sliding portion 2512 generates a force tending to move in the circumferential direction during the relative movement between the screw and the first sliding portion 2512, in order to limit the movement of the first sliding portion 2512 in the circumferential direction, a limit mechanism needs to be provided, for example, two screws are disposed in parallel along the longitudinal direction Z, and the first sliding portion 2512 is driven to move only along the longitudinal direction Z by the synchronous rotation of the two screws.

Of course, the present invention is not limited thereto, and the first moving module 251 may be a mechanism driven by a telescopic device, that is, the first driving portion 2513 may be a telescopic member (for example, an air cylinder), and the first sliding portion 2512 may be driven to reciprocate on the first rail by the telescopic motion of the first driving portion 2513, so that the first moving module 251 may be moved in the longitudinal direction Z.

For example, the first jacking module 252 may be one of a cylinder, an electric push rod, and a hydraulic cylinder.

The transfer mechanism 250 operates as follows:

when one of the tray modules 213 is transported by the transporting mechanism 230 to form a blank position, the first driving portion 2513 drives the first sliding portion 2512 to move to the next tray module 213 on the first rail portion 2511, to move to one end side of the tray module 213 away from the blank position, to be lifted up by the first lifting module 252 and contact with the tray module 213, to continue to lift up until the end side of the tray module 213 is higher than one end side near the blank position, to stop lifting up, and to drive the first sliding portion 2512 to move along the first rail portion 2511 to the blank position until the tray module 213 is completely moved to the blank position, and to transfer the tray module 213.

In one example of the present invention, the storage bin 210 further includes: the base portion 212 is configured to be coupled to a base,

is connected to the lower end of the storage part 211, and includes: an upper chassis 2121, a lower chassis 2122, and upright posts 2123, the upper chassis 2121 and the lower chassis 2122 being disposed in parallel along a height direction G, a plurality of the upright posts 2123 being connected between the upper chassis 2121 and the lower chassis 2122 to form a mounting cavity 2124, wherein the transfer mechanism 250 is disposed within the mounting cavity 2124;

for example, the upper base plate 2121, the lower base plate 2122 and the upright post 2123 are formed by welding, the stability of the storage bin 210 is ensured by the contact of the lower base plate 2122 with the ground, the upper base plate 2121 plays a role of supporting the storage portion 211, and the upright post 2123 can enable a mounting cavity 2124 to be formed between the upper base plate 2121 and the lower base plate 2122, so that the mounting of the conveying mechanism 250 is facilitated;

that is, the base portion 212 is disposed at the lower end of the storage portion 211 to support the storage portion 211, and the presence of the base portion 212 facilitates the installation of the conveying mechanism 250 and the first lifting mechanism 240, and further effectively maintains the storage bin 210 at a certain distance from the ground, thereby protecting the battery cover plate BP.

In one example of the present invention, the longitudinal direction Z of the upper plate 2121 is provided with a travel channel 21211 penetrating the upper plate 2121, and a span of the travel channel 21211 in the transverse direction H is smaller than a width of the tray module 213 in the transverse direction H;

that is, by providing the travel channel 21211, the first lifting module 252 can travel along the travel channel 21211, and then the conveying mechanism 250 can drag the tray module 213 in the longitudinal direction Z, and the span of the travel channel 21211 in the transverse direction H is smaller than the width of the tray module 213 in the transverse direction H, so that the tray module 213 can avoid sliding down from the travel channel 21211 during moving.

It should be noted that, the gap position of the upper base plate 2121 is further provided with a avoiding hole 21212, so that the lifting plate 241 mounted on the first lifting mechanism 240 passes through the upper base plate 2121 to lift the tray module 213 located at the gap position, and obviously, the area size of the avoiding hole 21212 is larger than the area size of the lifting plate 241 and smaller than the area occupied by the tray module 213 at the gap position.

In one example of the present invention, the tray storage rack 220 further has a second elevating mechanism 221 mounted thereon, and the second elevating mechanism 221 is configured to adjust the height of the empty tray 2131 stored in the storage cavity 2111;

after the suction cup 231 sucks the empty tray 2131 and moves to the tray storage rack 220 along the transverse direction H, and then the suction cup 231 releases the empty tray 2131 to fall into the tray storage rack 220, since the second lifting mechanism 221 is provided on the tray storage rack 220, the empty tray 2131 can be dropped onto the second lifting mechanism 221 which is lifted to a proper position, and as the number of the trays 2131 increases, the second lifting mechanism 221 gradually reduces the height until the lowest end of the tray storage rack 220 (for example, when the empty tray 2131 is placed on the second lifting mechanism 221, the second lifting mechanism 221 reduces the height of the thickness of the empty tray 2131, thereby maintaining the consistency of the height of the suction cup 231 placed in the tray storage rack 220), thereby avoiding damage caused by impact between the empty trays 2131 and protecting the empty tray 2131.

In one example of the invention, the gantry 232 includes:

a second moving module 233 including a second rail portion 2331, a second sliding portion 2332, and a second driving portion 2333;

wherein the suction cup 231 is fixedly connected to the second sliding part 2332;

for example, in the carrying mechanism 230, the second moving module 233 is a screw-and-rod mechanism, that is, a screw is pivotably disposed in the second guide rail, an output end of the second driving portion 2333 (for example, a motor) is connected to the screw, the second sliding portion 2332 is connected to the screw by a screw thread, and during the process of driving the screw to rotate forward and backward by the second driving portion 2333, the second sliding portion 2332 reciprocates along the second guide rail, so as to realize movement of the second moving module 233 in the transverse direction H; it should be noted that, during the relative movement between the screw rod and the second sliding portion 2332, the second sliding portion 2332 may generate a trend force of the circumferential movement, so that in order to limit the movement of the second sliding portion 2332 in the circumferential direction, a limiting mechanism needs to be provided, for example, two screw rods are disposed in parallel along the transverse direction H, and the second sliding portion 2332 is driven to move only along the transverse direction H by synchronous rotation of the two screw rods.

Of course, the present invention is not limited thereto, and the second moving module 233 may be a mechanism driven by a telescopic device, that is, the second driving portion 2333 may be a telescopic member (for example, an air cylinder), and the second sliding portion 2332 may be driven to reciprocate on the second rail by the telescopic motion of the second driving portion 2333, so that the second moving module 233 may be moved in the lateral direction H.

In one example of the present invention, the tray storage 220 is disposed within a range in which the rack 232 extends in the lateral direction H; this facilitates the suction cup 231 to place the sucked empty tray 2131 into the empty tray 2131 storage rack.

In one example of the present invention, further comprising: the controller is used for controlling the operation of the controller,

the controller is coupled to the second elevating mechanism 221 and configured to control the second elevating mechanism 221 to move along the height direction G.

During the operation of the transfer device 200, firstly, the controller controls the suction cup 231 on the carrying mechanism 230 to adsorb the battery cover plate BP on the tray 2131 in the storage cavity 2111 through negative pressure, then the controller controls the second sliding part 2332 to move to a designated station on one side away from the storage bin 210 along the second guide rail part 2332, then the controller controls the suction cup 231 to stop adsorbing to place the battery cover plate BP at the designated station, then the controller controls the second sliding part 2332 to move to the position of the tray module 213 along the second guide rail part 2331, the controller controls the suction cup 231 to adsorb the empty tray 2131 through negative pressure, the suction cup 231 adsorbing the empty tray 2131 is moved to one side of the storage bin 210 along the second guide rail part 2332 under the action of the controller, the controller controls the suction cup 231 to stop adsorbing and place the empty tray 2131 on the tray storage rack 220, finally the controller controls the first lifting mechanism 240 to lift the tray module 213 to lift one layer of the battery cover plate 2131 or the empty tray 2131;

when one of the tray modules 213 is transported by the transporting mechanism 230 and then forms a blank position, the controller controls the first driving portion 2513 to drive the first sliding portion 2512 to move on the first rail portion 2511 to the next tray module 213, and to move to one end side of the tray module 213 away from the blank position, and then controls the first lifting module 252 to lift upwards and contact with the tray module 213, and then continues to lift upwards until the end side of the tray module 213 is higher than one end side near the blank position, and then controls the first driving portion 2513 to drive the first sliding portion 2512 to move along the first rail portion 2511 to the blank position until the tray module is completely moved to the blank position, and then controls the transporting mechanism 230 to repeat the above steps to transport the tray module 213.

The transfer device 200 can greatly improve the feeding efficiency of the battery cover plate BP, can prevent the battery cover plate BP from being scratched, and is convenient to operate and high in reliability.
