Among them, lithium-ion cylindrical batteries are a type of battery commonly used in daily life and automotive electronics. During the battery production process, the battery cell needs to be loaded into the battery shell, and then the pole piece on the cap is welded to the pole ear on the battery cell. After welding, the cap is snapped on the battery shell to seal the battery. Two batteries are welded as a group. After the cap is welded, good and bad products are inspected, so that the good and bad products are transferred to different collection mechanisms. When one of the batteries in a group is defective, it is inevitable that there will be vacancies between the good batteries during the transfer process. The existing practice is to use a manipulator to grab good products to fill the vacancies. The structure is relatively complex, the production cost is high, and the speed is slow.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0021] like Figure 1-3As shown, the battery production rotary variable pitch lifting and translation mechanism includes a lifting and translation support 1 and a rotating frame 2. The lifting and translation support 1 is provided with a battery guide rail 3, an intermediate guide rail 4, a lifting drive mechanism 5, a translation drive mechanism 6 and a variable pitch mechanism 7. The rotating frame 2 is provided with a rotating mechanism 8 and a rotating drive mechanism 9 connected to the rotating mechanism 8. The lifting drive mechanism 5 and the translation drive mechanism 6 are both connected to the intermediate guide rail 4, and the variable pitch mechanism 7 is connected to the intermediate guide rail 4. It can be understood that the intermediate guide rail 4 is driven by the lifting drive mechanism 5 and the translation drive mechanism 6 to perform up and down lifting and left and right translation movements, and the variable pitch mechanism 7 is also driven by the intermediate guide rail 4 to perform up and down lifting and left and right translation movements. At the same time, the variable pitch mechanism 7 can perform left and right telescopic movements relative to the intermediate guide rail 4; the rotating mechanism 8 is driven by the rotating drive mechanism 9 to perform rotational movement, so that the batteries 23 that are good products are continuously connected.

[0022] Specifically, the rotating drive mechanism 9 includes a rotating drive motor 10 and a rotating shaft 11 transmission-connected to the rotating drive motor 10, and the rotating mechanism 8 includes a rotating battery holder 12 connected to the rotating shaft 11; the rotating battery holder 12 is provided with a plurality of battery placement grooves 13 and a battery baffle 14, and a magnetic block is provided in the battery placement groove 13 to attract the battery. It can be understood that the battery baffle 14 is in a square shape and its vertices are distributed on the rotating battery seat 12. Each battery baffle 14 corresponds to two groups of battery placement grooves 13. Two batteries can be connected to each battery baffle 14 at a time. The two groups of battery placement grooves 13 receive the two batteries respectively. It is worth noting that only good batteries will be connected to the rotating battery seat 12. If one of the two batteries is defective, there will be batteries on one group of battery placement grooves, while there will be no batteries on the other group of battery placement grooves (the defective batteries are not transferred). The battery 23 is first pushed onto the battery baffle 14 on the side of the rotating battery seat 12. After the rotating battery seat 12 rotates, it brings the battery 23 to the highest point. At this time, the battery 23 changes from a vertical state to a horizontal state, waiting for the middle guide rail 4 and the pitch change mechanism 7 to come and lift it away, and the cycle continues.

[0023] Specifically, the lifting drive mechanism 5 includes a lifting double-stroke cylinder 15 and a lifting shaft 16 that is transmission-connected to the lifting double-stroke cylinder 15, and the lifting shaft 16 is connected to the bottom of the intermediate guide rail 4; the translation drive mechanism 6 includes a screw motor 17 and a screw nut 18 that is transmission-connected to the screw motor 17, and a translation bracket 19 is sleeved on the outer side of the screw nut 18, and the translation bracket 19 is connected to the intermediate guide rail 4; the intermediate guide rail 4 is located on the inner side of the battery guide rail, and a plurality of battery supporting grooves 20 are provided on the intermediate guide rail 4 and the battery guide rail 3, and a magnetic block is provided in the battery supporting groove 20. It can be understood that the screw motor 17 drives the screw nut 18 and the translation bracket 19 to perform left and right translational motion, thereby driving the intermediate guide rail 4 to perform left and right translational motion, and the lifting double-stroke cylinder 15 drives the lifting shaft 16 to perform up and down lifting motion, thereby driving the intermediate guide rail 4 to perform up and down lifting and translational motion.

[0024] Specifically, the pitch-changing mechanism 7 includes a slide cylinder 21 and a pitch-changing telescopic seat 22, the pitch-changing telescopic seat 22 is transmission-connected to the slide cylinder 21, the slide cylinder 21 is mounted at the end of the middle guide rail 4, the upper end of the pitch-changing telescopic seat 22 is flush with the upper end of the middle guide rail 4, and the slide cylinder 21 is located at the bottom of the middle guide rail 4. It can be understood that the slide cylinder 21 is used to drive the pitch-changing telescopic seat 22 to extend or retract according to different control signals.

[0025] It can be understood that the lifting double-stroke cylinder 15, the screw motor 17 and the slide cylinder 21 can all be connected to a PLC controller, and the PLC controller can be connected to an external battery detection mechanism. When it is detected that there is a battery or no battery in the battery placement groove 13 on the rotating battery seat 12, the PLC controller outputs a corresponding control signal to the lifting double-stroke cylinder 15, the screw motor 17 and the slide cylinder 21, thereby controlling the middle guide rail to lift or translate a corresponding distance, and the variable pitch telescopic seat to extend and retract a corresponding distance to support the battery 23, thereby ensuring that the battery rail 3 is filled with batteries in sequence without leaving any empty spaces.

[0026] It can be understood that the above-mentioned cylinder and motor can be universal cylinders and motors, etc., used to provide driving power, and the present invention is not limited thereto.

[0027] It can be understood that the present invention has a reasonable design and a unique structure. The rotating mechanism 8 is provided to connect the good batteries, and the variable pitch mechanism 7, the translation drive mechanism 6, the lifting drive mechanism 5 and the intermediate guide rail 4 cooperate to transfer the batteries, so that the batteries on the rotating mechanism 8 can be transferred to the battery rail 3 with variable pitch, thereby avoiding the occurrence of empty spaces on the battery rail 3. In addition, the transfer speed is fast, which can greatly improve the battery transfer efficiency, the work efficiency is high, and can meet the needs of mass production.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
