Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a battery cell loading and membrane transfer device and a battery cell loading production line. Background Technology

[0002] Lithium-ion batteries have advantages such as long lifespan and high energy density, and are therefore widely used in portable electronic devices, automobiles, and many other fields. A lithium-ion battery consists of a cell and a casing, and its production process includes the step of inserting the cell into the outer casing. In existing patents, Chinese patent application number 201710193077.9 discloses a cell insertion device and a cell insertion method. This cell insertion device includes a loading section, a conveying section, and a transport section. The conveying section includes a conveying device and at least two supporting devices. The supporting devices are configured to carry the cell casing, and the conveying device is configured to simultaneously drive at least two supporting devices to circulate between the loading section and the transport section. The conveying section transports at least two supporting devices. This patent document describes a process where a loading section detaches the picked-up battery cell, which is then placed into a battery cell casing on a carrier device located below the loading section. A control and transport section then removes the battery cell casing from the first carrier device located at the battery cell casing unloading point, and places the empty battery cell casing onto the first carrier device that has already removed the casing. In other words, this patent document first places the empty battery cell casing onto the carrier device via the transport section, then places the battery cell into the recess of the empty battery cell casing via the loading section, and finally removes the battery cell and battery cell casing via the transport section. This requires two carrier devices to be switched back and forth to improve the efficiency of battery cell insertion, but it increases the number of carrier devices and conveying devices, thus increasing costs. Therefore, the drawbacks are obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a battery cell insertion and membrane transfer device and a battery cell insertion production line.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A battery cell insertion and membrane housing transfer device includes a base, a lifting drive mechanism mounted on the base, a lifting arm slidably connected to the base and connected to the lifting end of the lifting drive mechanism, and a suction plate mounted on the lifting arm.

[0019] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0020] like Figures 1 to 3 As shown, this utility model provides a battery cell insertion and membrane shell transfer device, which includes a base 1, a lifting drive mechanism 2 mounted on the base 1, a lifting arm 3 slidably connected to the base 1 and connected to the lifting end of the lifting drive mechanism 2, and a suction plate 4 mounted on the lifting arm 3. The suction plate 4 is provided with a vacuum channel 5, a plurality of battery cell suction cups 6 and a plurality of membrane shell suction cups 7. The plurality of battery cell suction cups 6 and the plurality of membrane shell suction cups 7 are all connected to the vacuum channel 5. The plurality of membrane shell suction cups 7 are distributed on both sides of the plurality of battery cell suction cups 6. The plurality of battery cell suction cups 6 form a battery cell suction area 8, and the plurality of membrane shell suction cups 7 form a membrane shell suction area 9. The battery cell suction area 8 is used to pick up battery cells, and the membrane shell suction area 9 is used to pick up membrane shells. Specifically, the battery cell insertion and membrane shell transfer device also includes a moving drive mechanism 25 drivenly connected to the base 1. The moving drive mechanism 25 is used to drive the base 1 to move horizontally back and forth. The vacuum channel 5 is connected to the vacuum pumping mechanism via an air pipe.

[0021] In practical applications, the moving drive mechanism 25 drives the base 1 and suction plate 4 to move, while the lifting drive mechanism 2 drives the base 1 and suction plate 4 to rise and fall. This allows the suction plate 4 to first move above the battery cell and pick it up through the battery cell suction area 8. Then, the suction plate 4 moves above the membrane housing with its recesses and picks up the membrane housing through the membrane housing suction area 9. At this point, the battery cell is placed precisely in the recess of the membrane housing, achieving battery cell insertion. Then, with the coordinated operation of the moving drive mechanism 25 and the lifting drive mechanism 2, the suction plate 4 can simultaneously transfer the battery cell and membrane housing together. Compared to existing technologies that require one robotic arm to pick up the perforated or top-cut membrane housing onto the packaging fixture 19, and another robotic arm to pick up the battery cell and place it into the recess of the membrane housing, this battery cell insertion and membrane housing transfer device can complete the battery cell insertion and the synchronous transfer of the inserted battery cell and membrane housing to the packaging fixture 19. This reduces the number of robotic arms used, lowers costs, and significantly improves production efficiency.

[0022] In this embodiment, the lifting arm 3 is slidably connected to the base 1 via the vertical guide rail 10. During the lifting process of the lifting arm 3, the vertical guide rail 10 plays a guiding role, improving the stability of the lifting arm 3 during lifting.

[0023] In this embodiment, the lifting drive mechanism 2 includes a lead screw 11 vertically rotatably connected to the base 1, a movable nut 12 threaded onto the lead screw 11, and a motor 13 mounted on the base 1. The output shaft of the motor 13 is fixedly connected to one end of the lead screw 11 via a coupling, and the lifting arm 3 is fixedly connected to the movable nut 12. In practical applications, the motor 13 drives the lead screw 11 to rotate, and the rotating lead screw 11 drives the movable nut 12, along with the lifting arm 3, to move up and down along the axial direction of the lead screw 11.

[0024] In this embodiment, the base 1 is equipped with a vacuum measuring instrument 14 for detecting the vacuum level of the vacuum channel 5. The vacuum measuring instrument 14 detects the vacuum level in the vacuum channel 5 in real time to ensure that the battery core area 8 and the membrane shell area 9 have sufficient suction to hold the battery core and membrane shell tightly. The vacuum measuring instrument 14 also displays the magnitude of the vacuum level, making it easy to adjust the vacuum level.

[0025] This utility model also provides a battery cell loading production line, including the aforementioned battery cell loading and membrane transfer device. This battery cell loading production line possesses all the beneficial effects of the battery cell loading and membrane transfer device, which will not be elaborated further here.

[0026] In this embodiment, the battery cell casing production line also includes a casing punching mechanism 15, a casing ejection robot 16, a casing top cutting mechanism 17, a battery cell feeding mechanism 18, a packaging fixture 19, a packaging transfer robot 20, and a packaging mechanism 21. The casing punching mechanism 15 is equipped with a casing punching mold. The casing punching mechanism 15, the casing top cutting mechanism 17, the battery cell feeding mechanism 18, and the packaging fixture 19 are arranged in a straight line. The casing ejection robot 16 is used to eject the casing punched by the casing punching mold onto the casing top cutting mechanism 17. The moving drive mechanism 25 is used to drive the base 1 and the suction plate 4 to move between the casing top cutting mechanism 17, the battery cell feeding mechanism 18, and the packaging fixture 19. A loading position 22 is provided between the battery cell feeding mechanism 18 and the packaging mechanism 21. The packaging transfer robot 20 is used to drive the packaging fixture 19 to move between the loading position 22 and the packaging mechanism 21.

[0027] In practical applications, the membrane shell to be punched is placed in the membrane shell punching mold after the mold is opened. Then, the membrane shell punching mold closes to punch and form the membrane shell, thus stamping out the recesses on the membrane shell. The membrane shell unloading robot 16 picks up the membrane shell with the recesses formed on the membrane shell punching mold after the mold is opened and places it onto the membrane shell top cutting mechanism 17. The membrane shell top cutting mechanism 17 cuts the membrane shell. At the same time, the battery cell feeding mechanism 18 supplies the battery cells to the feeding position. Then, the battery cell insertion and membrane shell transfer device... The battery cell suction area 8 first picks up the battery cell at the feeding position, and then moves the battery cell into the recess of the top-cut film shell to realize the battery cell insertion. The film shell suction area 9 picks up the film shell after the pit is punched, so that the battery cell and film shell after insertion are picked up at the same time and transferred synchronously to the packaging fixture 19. The packaging fixture 19 folds the film shell to cover the battery cell. Then, the packaging transfer robot 20 drives the packaging fixture 19 to move to the packaging mechanism 21. The packaging mechanism 21 packages the folded film shell.

[0028] In this embodiment, the battery cell feeding mechanism 18 includes a feeding translation module 23 and a feeding platform 24 connected to the translation end of the feeding translation module 23. The feeding platform 24 is used to carry the battery cells. In practical applications, the feeding platform 24 carries the battery cells. The feeding translation module 23 drives the feeding platform 24, along with the battery cells, to move from the outside to the feeding position. Then, the moving drive mechanism 25 drives the base 1, along with the suction plate 4, to move to the feeding position, so that the battery cell suction area 8 of the suction plate 4 of the battery cell insertion and membrane transfer device can pick up the battery cells on the feeding platform 24.

[0029] Specifically, the feeding translation module 23 can be a lead screw module.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
