Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical lithium battery processing equipment, in particular to a gluing mechanism for cylindrical lithium batteries. Background Art

[0002] After the processing of cylindrical batteries is completed, it is generally necessary to stick a layer of tape or adhesive tape on the outer surface to protect the batteries and insulate them. The existing technology mainly uses automatic gluing machines to gluing cylindrical batteries. When in use, workers will neatly stack the cylindrical batteries to be processed on the substrate, and use the feeding structure to feed the batteries on the substrate one by one to the gluing station for gluing. The feeding structure includes: a rotating drum arranged in the substrate, and a number of battery slots are opened on the surface of the drum. The drum is driven by a motor. After the battery slides into the battery slot along the substrate, the motor drives the drum to rotate and rotates the battery to the desired position. Then the battery in the battery slot is pushed into the gluing station by the cylinder for gluing.

[0003] Current technical problems: During actual use, multiple batteries are prone to collide with each other during unloading, generating external forces, which cause the batteries to deviate from the expected position due to the external forces. This results in the batteries not being able to accurately enter the rotating grooves on the surface of the drum, causing blockage of the feeding structure and affecting the battery processing efficiency. Utility Model Content

[0004] In view of this, the purpose of the present invention is to propose a gluing mechanism for cylindrical lithium batteries to solve the technical problem that batteries in existing cylindrical lithium battery gluing machines easily collide with each other during unloading, causing dislocation and thus blocking the feeding structure.

[0007] a stopper located in the guide channel, the stopper dividing the guide channel into an upper guide area and a lower guide area;

[0008] A driving structure is used to control the stopper to open and close the guide channel. When the stopper opens the guide channel, a gap is formed at the intersection of the upper guide area and the lower guide area through which a single battery can pass. After the battery passes through the gap, the stopper closes the guide channel.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs.

[0034] like Figure 1 and Figure 2 As shown, a gluing mechanism for cylindrical lithium batteries is arranged in front of a gluing station to guide the feeding structure, comprising:

[0035] A box for receiving batteries, the box comprising a base plate 1 having a first guide surface 15 and a second guide surface 16, wherein a guide channel for conveying batteries is formed between the first guide surface 15 and the second guide surface 16, and a feeding structure is located at the end of the guide channel;

[0036] a stopper 17 located in the guide channel, the stopper 17 dividing the guide channel into an upper guide area and a lower guide area;

[0037] A drive structure for controlling the stopper 17 to open and close the guide channel. When the stopper 17 opens the guide channel, a gap is formed at the intersection of the upper guide area and the lower guide area so that a single battery can pass through. After the battery passes through the gap, the stopper 17 closes the guide channel.

[0038] The above technical solution can prevent batteries from colliding with each other during the unloading process, causing the batteries to deviate from the expected position. When in use, all batteries that need to be glued are placed in the upper guide area. When the batteries need to be fed into the feeding structure, the drive structure is started to drive the stopper 17 to open the guide channel, so that a gap is formed at the junction of the upper guide area and the lower guide area through which a single battery can pass. After the battery passes through the gap and enters the lower guide area, the stopper 17 closes the guide channel to block the gap. When closing the guide channel, the stopper 17 will also generate a thrust on the battery in the upper guide area to prevent the battery from being stuck in the gap. The battery entering the lower guide area then enters the feeding structure, and is sent to the gluing station through the feeding structure for gluing. Therefore, the batteries can be unloaded one by one, preventing the batteries from colliding with each other, causing the expected position to deviate and block the unloading.

[0039] like Figure 3 and Figure 4 As shown, in this embodiment, the box body further includes side panels 2 respectively arranged at the front and rear of the base plate 1, and the side panels 2 form a shield for the front and rear of the guide channel; the feeding structure includes: a rotating drum 4 with a battery slot 5 opened on the circumferential surface, and the rotating drum 4 rotates in cooperation with the rotating slot 3 opened in the base plate 1; a power structure for driving the rotating drum 4 to rotate in the rotating slot 3; specifically, the power structure includes a motor 10 connected to the side panel 2, the output shaft of the motor 10 passes through the side panel 2 and is connected to the shaft slot 11 opened in the rotating drum 4; a cylinder 12 is provided on one side of the side panel 2, and a push block 13 is connected to the output end of the cylinder 12, and the push block 13 slides in cooperation with the through slot 14 opened on the surface of the side panel 2;

[0040] The above technical solution can be used to deliver the battery to the gluing station. When the battery enters the lower guide area and then enters the battery slot 5 of the rotating drum 4, the motor 10 drives the rotating drum 4 to rotate, thereby rotating the battery to a position aligned with the through slot 14. Then the output end of the cylinder 12 drives the push block 13 to extend into the through slot 14 and the battery slot 5 in turn, thereby pushing the battery from the battery slot 5 into the gluing station to complete automatic unloading.

[0041] like Figure 2 As shown, in this embodiment, a rotating shaft 18 is provided at both ends of the stopper 17, and the rotating shaft 18 passes through the side plates 2 on the front and rear sides; the driving structure includes: a torsion spring 19 connected to one of the rotating shafts 18, and the other end of the torsion spring 19 is connected to the side plate 2; a first gear 24 connected to the other rotating shaft 18; a second gear 23 rotatably provided on the side plate 2, and the circumference of the second gear 23 has a section of teeth meshing with the first gear 24; the second gear 23 is transmission-connected to the output shaft of the motor 10; specifically, a bracket 9 for fixing the motor 10 is provided on the outer side of the side plate 2, the output shaft of the motor 10 is connected to the first belt pulley 20, the second gear 23 is connected to the second belt pulley 21, and a belt 22 is provided between the first belt pulley 20 and the second belt pulley 21;

[0042] The above technical solution can realize that when the motor 10 drives the rotating drum 4 to rotate, it can synchronously drive the stopper 17 to open or close the guide channel. When the motor 10 is working, its output shaft drives the rotating drum 4 while also driving the first belt pulley 20 to rotate. The first belt pulley 20 drives the second belt pulley 21 to rotate through the belt 22, and the second belt pulley 21 drives the second gear 23 to rotate. Since the second gear 23 has partial teeth on the circumference, these partial teeth can drive the first gear 24 to engage, so that the first gear 24 can be driven to rotate intermittently. When the first gear 24 rotates, it will drive the rotating shaft 18 to rotate, thereby driving the stopper 17 connected to the rotating shaft 18 to rotate. The stopper 17 opens the guide channel. When the rotating shaft 18 rotates, the torsion spring 19 accumulates energy. When the battery enters the lower guide area, the teeth on the surface of the second gear 23 just disengage from the first gear 24. The torsion spring 19 drives the rotating shaft 18 and the stopper 17 to reset, thereby blocking the guide channel. During the reset process of the stopper 17, the battery located in the upper guide area will be pushed back to its original position.

[0043] like Figure 2 As shown, in this embodiment, a mounting plate 25 is provided at the bottom of the box body, and a mounting hole 26 is opened on the surface of the mounting plate 25;

[0044] The above technical solution can be used to conveniently install the device on the glue sticking machine, and the device can be detachably installed by means of bolts.

[0045] like Figure 4 As shown, in this embodiment, a positioning member is threadedly connected to the surface of the side plate 2, and the positioning member has a cylindrical end 7 and a threaded end 8. The cylindrical end 7 is rotatably engaged with the positioning hole 6 opened in the rotating drum 4;

[0046] The above technical solution can adjust the rotation stability of the drum 4 and prevent the drum 4 from shifting forward and backward during rotation. By tightening the positioning piece, the cylindrical end 7 of the positioning piece can be driven to apply thrust to the positioning hole 6 of the drum 4. The output shaft of the motor 10 and the cylindrical end 7 can apply thrust to the drum 4 on both sides to prevent the drum 4 from shifting forward and backward.

[0047] The stopper 17 is driven to open the guide channel, so that a gap is formed at the intersection of the upper guide area and the lower guide area so that a single battery can pass through. After the battery passes through the gap and enters the lower guide area, the stopper 17 closes the guide channel to block the gap. When closing the guide channel, the stopper 17 also generates a thrust on the battery in the upper guide area to prevent the battery from being stuck in the gap. The battery entering the lower guide area then enters the feeding structure.

[0048] Working principle: Put all the batteries that need to be glued into the upper guide area. When the batteries need to be sent to the battery slot 5 of the drum 4, start the motor 10 to drive the first belt pulley 20 to rotate. The first belt pulley 20 drives the second belt pulley 21 to rotate through the belt 22. The second belt pulley 21 drives the second gear 23 to rotate. Since the second gear 23 has some teeth on its circumference, these teeth can drive the first gear 24 to engage, so that it can intermittently drive the first gear 24 to rotate. When the first gear 24 rotates, it will drive the rotating shaft 18 to rotate, thereby driving the stopper 17 connected to the rotating shaft 18 to rotate. The stopper 17 opens the guide channel. A gap is formed at the intersection between the upper guide area and the lower guide area so that a single battery can pass through. The battery enters the lower guide area through the gap. When the rotating shaft 18 rotates, the torsion spring 19 accumulates energy. At the moment the battery enters the lower guide area, the teeth on the surface of the second gear 23 are just disengaged from the first gear 24. The torsion spring 19 drives the rotating shaft 18 and the stopper 17 to reset, thereby blocking the guide channel. During the resetting process of the stopper 17, the battery located in the upper guide area will be pushed back to its original position. Subsequently, the output end of the cylinder 12 drives the push block 13 to extend into the through groove 14 and the battery slot 5 in turn, thereby pushing the battery from the battery slot 5 into the gluing station to complete automatic unloading.
