Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and in particular to a multifunctional integrated intelligent production line for cylindrical lithium batteries. Background Art

[0002] Cylindrical lithium battery, also known as "cylindrical lithium-ion battery", is one type of lithium-ion battery. During the battery production process, a groove rolling machine is used to roll grooves on the cylindrical lithium battery steel shell.

[0003] At present, in the process of grooving cylindrical lithium battery steel shells, the staff puts the steel shells on the placement grooves on the conveyor belt, and the roller grooves the steel shells during the movement of the conveyor belt. However, the position of the steel shells is not fixed at this time. During the grooving, the steel shells will rotate synchronously with the rotation of the roller, especially when rolling deep grooves. At this time, the steel shells are subjected to a large rotational force from the roller, which makes it easy for the steel shells to flow out of the placement grooves. At this time, the roller will damage other positions of the steel shells, resulting in the scrapping of the steel shells, and the machine needs to be stopped to handle the faults, which reduces the efficiency of grooving the steel shells.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The conveying mechanism includes a plurality of first blocks 5 fixedly connected to the side wall of one of the conveyor belts 4, the side wall of the first block 5 is rotatably connected to a cylinder 6, the side wall of the cylinder 6 is fixedly connected to a conveying plate 7, the upper end of the conveying plate 7 is provided with a first groove 8 and a second groove 12, and the second groove 12 is arranged near the first block 5 (such as Figure 6 As shown, a lithium battery housing 9 is provided in the first slot 8, and two opposite inner walls of the first slot 8 are elastically connected with an arc plate 11 (as shown in FIG. 1 ) via a plurality of first springs 10. Figure 2 and Figure 5 As shown in the figure), the inner side wall of the arc plate 11 is in contact with the side wall of the lithium battery housing 9.

[0033] A feeding plate 34 is fixedly connected to the inner wall of the conveying frame 1 near the opening, and a storage frame 35 is fixedly connected to the upper end of the conveying frame 1 away from the feeding plate 34. It should be noted that a lithium battery shell 9 is provided in the storage frame 35, which can intermittently enter the first slot 8 through an external control mechanism. This is a prior art and will not be elaborated here.

[0034] The conveying frame 1 is provided with a clamping mechanism for clamping the lithium battery housing 9, and the clamping mechanism includes a second rod 13 fixedly connected to the side wall of the cylinder 6, the side wall of the second rod 13 is rotatably connected to the side wall of the first block 5, a rectangular rod 14 is penetrated through the second rod 13, and the end of the rectangular rod 14 away from the second rod 13 is located in the second groove 12, and the side walls of the two arc plates 11 away from each other are fixedly connected with L-shaped rods 15 (such as Figure 5 As shown in the figure, the side wall of the L-shaped rod 15 passes through the inner wall of the first groove 8 and extends into the second groove 12, and the inner wall of the first groove 8 is provided with a sliding groove that cooperates with the L-shaped rod 15. The side wall of the rectangular rod 14 is rotatably connected to the side wall of the L-shaped rod 15 through the rotating rod 16, so that when the rectangular rod 14 moves in a direction away from the lithium battery housing 9, the rectangular rod 14 can drive the two arc plates 11 to approach each other through the two rotating rods 16 and the two L-shaped rods 15, and clamp the lithium battery housing 9. When the rectangular rod 14 moves in a direction close to the lithium battery housing 9, the rectangular rod 14 can drive the two arc plates 11 to move away from each other through the two rotating rods 16 and the two L-shaped rods 15, and loosen the lithium battery housing 9.

[0035] A first annular groove 17 is provided on the inner wall of the conveying frame 1 near the first block 5. The first annular groove 17 is in the shape of a runway. The first annular groove 17 is located at the inner bottom at the top and is fixedly connected to a first wedge-shaped strip 18. The side wall of the rectangular rod 14 away from the rotating rod 16 is fixedly connected to a fixing rod 19. The side wall of the fixing rod 19 is rotatably connected to a first wedge-shaped plate 20 that cooperates with the first wedge-shaped strip 18. The lower surface of the first wedge plate 20 is in contact with the inner circle side wall of the first annular groove 17.

[0036] like Figure 4 - Figure 6 As shown, during the movement of the first block 5, the side wall of the first wedge plate 20 will fit with the side wall of the first wedge strip 18. At this time, the side wall of the first wedge strip 18 supports the side wall of the first wedge plate 20, so that the rectangular rod 14 moves away from the lithium battery housing 9, thereby realizing automatic clamping of the lithium battery housing 9 during transportation, thereby avoiding the prior art in which the lithium battery housing 9 is not clamped, resulting in the lithium battery housing 9 being subjected to a large rotational force of the roller 25, making it easy for the lithium battery housing 9 to flow out of the placement groove. At this time, the roller 25 will damage other positions of the lithium battery housing 9, resulting in the scrapping of the lithium battery housing 9, and the machine needs to be stopped to handle the fault, thereby reducing the rolling efficiency of the lithium battery housing 9.

[0037] The inner bottom of the first annular groove 17 is fixedly connected with a toothed plate 21, and the side wall of the second rod 13 is fixedly connected with a gear 22. The gear 22 meshes with the toothed plate 21 during movement, so that after the gear 22 meshes with the toothed plate 21 during movement, the cylinder 6 drives the conveying plate 7 to rotate, so that the lithium battery housing 9 can rotate during movement after clamping.

[0038] like Figure 5 and Figure 6 As shown, the length of the first wedge-shaped strip 18 is greater than the length of the tooth plate 21 , that is, during the conveying process of the lithium battery housing 9 , the lithium battery housing 9 is first clamped and then rotated.

[0039] The grooving mechanism includes a vertical plate 23 fixedly connected to the upper end of the conveying frame 1, and the side wall of the vertical plate 23 is rotatably connected to the roller 25 through the third rod 24. The side wall of the conveying frame 1 is fixedly connected to the motor 26 through a bracket, and the output end of the motor 26 is fixedly connected to one end of one of the first rods 2, and the side wall of the output shaft of the motor 26 is fixedly connected to the first wheel 27. The end of the third rod 24 away from the roller 25 is fixedly connected to the second wheel 28, and a synchronous belt is connected between the first wheel 27 and the second wheel 28. It should be noted that the diameter of the first wheel 27 is much larger than the diameter of the second wheel 28, so that the second wheel 28 can rotate quickly when the first wheel 27 rotates.

[0040] like Figure 1 and Figure 7 As shown, during the process of clamping and conveying the lithium battery shell 9 , the rotating roller 25 can roll grooves on the surface of the rotating lithium battery shell 9 , thereby accelerating the efficiency of rolling grooves on the surface of the lithium battery shell 9 .

[0041] The side wall of the vertical plate 23 is rotatably connected to the fourth rod 29, the side wall of the fourth rod 29 is fixedly connected to the fixed cylinder 30, the side wall of the fixed cylinder 30 is fixedly connected to a plurality of bristles 31, the side wall of the third rod 24 is fixedly connected to the third wheel 32, the side wall of the fourth rod 29 is fixedly connected to the fourth wheel 33, and a synchronous belt is connected between the third wheel 32 and the fourth wheel 33. During the rotation of the hob 25, the third rod 24 drives the fixed cylinder 30 and the plurality of bristles 31 to rotate through the third wheel 32, the synchronous belt, the fourth wheel 33 and the fourth rod 29 to clean the surface of the lithium battery shell 9 after grooving to prevent debris generated by grooving from adhering to the surface of the lithium battery shell 9 and affecting subsequent production.

[0042] A plurality of second blocks 36 are fixedly connected to the side wall of the conveyor belt 4 away from the first block 5. The plurality of first blocks 5 correspond to the plurality of second blocks 36 one by one. The inner wall of the conveyor frame 1 facing the first annular groove 17 is provided with a second annular groove 42 (such as Figure 3 and Figure 4As shown), the side wall of the second block 36 is slidably connected to a protective rod 37, the protective rod 37 is rotatably connected to the side wall of the lithium battery housing 9 with a push ring 38, the second annular groove 42 is located at the upper inner bottom and is fixedly connected to a second wedge strip 39, the side wall of the protective rod 37 away from the push ring 38 is fixedly connected to a second wedge plate 40 that cooperates with the second wedge strip 39, and the side wall of the second block 36 is elastically connected to the corresponding side wall of the second wedge plate 40 through a plurality of second springs 41.

[0043] like Figure 5 and Figure 6 As shown, the length of the second wedge strip 39 is greater than the length of the first wedge strip 18. After the lithium battery housing 9 falls into the first groove 8, before the first wedge plate 20 contacts the first wedge strip 18, the side wall of the second wedge plate 40 fits with the side wall of the second wedge strip 39, and then the second wedge strip 39 squeezes and moves the protective rod 37 and the push ring 38 through the second wedge plate 40, so that the protective rod 37 enters the lithium battery housing 9, and the push ring 38 pushes the lithium battery housing 9 to abut against the inner wall of the first groove 8, thereby ensuring the accuracy of the rolling groove position of the lithium battery housing 9 after clamping, and the protective rod 37 can support the inner wall of the lithium battery housing 9 to prevent the side wall of the lithium battery housing 9 from being damaged due to rolling groove collapse.

[0044] In the production process of the lithium battery shell 9, the lithium battery shell 9 is first placed in the storage frame 35, and then the driving motor 26 rotates, at which time the two first rods 2 and the four rollers 3 drive the two conveyor belts 4 to move from left to right (such as Figure 2 As shown), at this time, the two conveyor belts 4 respectively drive the multiple first blocks 5 and the multiple second blocks 36 to move;

[0045] When the first groove 8 on the conveying plate 7 moves to face the bottom of the material storage frame 35, the lithium battery shells 9 in the material storage frame 35 will fall into the first groove 8 individually under the action of the external control mechanism. Then, as the conveyor belt 4 continues to move, since the length of the second wedge strip 39 is greater than the length of the first wedge strip 18, after the lithium battery shell 9 falls into the first groove 8, before the first wedge plate 20 contacts the first wedge strip 18, the side wall of the second wedge plate 40 fits with the side wall of the second wedge strip 39, and then the second wedge strip 39 squeezes and moves the protective rod 37 and the push ring 38 through the second wedge plate 40, so that the protective rod 37 enters the lithium battery shell 9, and the push ring 38 pushes the lithium battery shell 9 to abut against the inner wall of the first groove 8, thereby ensuring the accuracy of the rolling groove position of the lithium battery shell 9 after clamping;

[0046] Then, during the movement of the first block 5, the side wall of the first wedge plate 20 will fit with the side wall of the first wedge strip 18, and the side wall of the first wedge strip 18 supports the side wall of the first wedge plate 20, so that the rectangular rod 14 moves away from the lithium battery housing 9. At this time, the rectangular rod 14 can drive the two arc plates 11 to approach each other through the two rotating rods 16 and the two L-shaped rods 15, and clamp the lithium battery housing 9, and the clamping process ends until the first wedge strip 18 is separated from the first wedge plate 20;

[0047] Since the length of the first wedge-shaped strip 18 is greater than the length of the tooth plate 21, that is, during the conveying process of the lithium battery housing 9, the lithium battery housing 9 is first clamped, and then the lithium battery housing 9 continues to move, so that the gear 22 rotates after meshing with the tooth plate 21 during the movement, and at this time, the cylinder 6 drives the conveying plate 7 to rotate, so that the lithium battery housing 9 rotates after being clamped;

[0048] The motor 26 rotates through the first wheel 27, the synchronous belt, the second wheel 28 and the third rod 24 to drive the roller 25 to rotate quickly. When the lithium battery housing 9 moves to the roller 25, the rotating roller 25 can roll grooves on the surface of the rotating lithium battery housing 9, thereby accelerating the efficiency of rolling grooves on the surface of the lithium battery housing 9.

[0049] When the lithium battery shell 9 passes through the fixed cylinder 30 after rolling the groove, the third rod 24 drives the fixed cylinder 30 and the plurality of brushes 31 to rotate through the third wheel 32, the synchronous belt, the fourth wheel 33 and the fourth rod 29 during the rotation of the hob 25, so as to clean the surface of the lithium battery shell 9 after the rolling of the groove, so as to prevent the debris generated by the rolling of the groove from adhering to the surface of the lithium battery shell 9 and affecting the subsequent production;

[0050] Then, as the lithium battery housing 9 continues to move, when the gear 22 and the toothed plate 21 separate, the position of the first slot 8 is located directly above, and then the first wedge plate 20 and the first wedge strip 18 separate, and then the two arc plates 11 move away from each other under the action of the two first springs 10, loosening the lithium battery housing 9, and the second wedge plate 40 and the second wedge strip 39 separate, so that the protective rod 37 moves out of the lithium battery housing 9 under the action of the multiple second springs 41, and then the lithium battery housing 9 falls from the first slot 8 to the feeding plate 34 and moves out;

[0051] Through the integrated design of clamping, limiting, rotating, grooving and cleaning during the movement of the lithium battery housing 9, there is no need for separate settings, making the production of the lithium battery housing 9 multifunctional and integrated, which is in line with the current direction of industrial development.

[0052] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
