Description

Technical Field

[0001] The present invention relates to a lithium battery packaging device, and in particular to a lithium battery dispensing packaging device capable of achieving single-edge folding or double-edge folding. Background Art

[0002] Currently, during the production and processing of lithium batteries, the outer cut edges of the aluminum-plastic film are exposed to the outside by metal. To ensure the insulation of the battery cell, a strip of UV adhesive is applied to the outer end of the aluminum-plastic film. After the UV adhesive is cured, hot melt adhesive is applied to the edges of the aluminum-plastic film. The horizontally extending aluminum-plastic film is then bent and attached to the sides of the battery cell to form the entire battery cell body. Existing packaging methods only support one method: single folding (which requires UV adhesive sealing) or double folding (which requires two foldings for sealing). Simultaneous folding and sealing of both methods on the same packaging conveyor line is not possible. Furthermore, the existing double-folding packaging method does not fold the edges 180 degrees, resulting in leakage and other issues at the edges and corners of the aluminum-plastic film, resulting in poor packaging results.

[0065] like Figures 1-19 As shown, a lithium battery dispensing packaging equipment capable of achieving single or double folding includes a first side packaging conveyor line 1 and a second side packaging conveyor line 2. Both ends of the first side packaging conveyor line 1 and the second side packaging conveyor line 2 are connected by a transfer mechanism 3. The carrier 4 transported on the first side packaging conveyor line 1 can be moved and transported to the second side packaging conveyor line 2 for transportation through the transfer mechanism 3. The carrier 4 transported on the second side packaging conveyor line 2 can be moved and transported to the first side packaging conveyor line 1 for transportation through the transfer mechanism 3. The first side packaging conveyor line 1 and the second side packaging conveyor line 2 are sequentially provided with a precision positioning mechanism 6, a trimming mechanism 7, a folding mechanism 8, a pressing mechanism 9, and a CCD folding inspection mechanism from the feeding end to the discharging end. Mechanism 10, 180-degree folding mechanism 11, hot pressing mechanism 12, hot melt glue point mechanism 13, CCD hot melt glue inspection mechanism 14, 90-degree folding mechanism 15, two hot pressing mechanisms 16 and two cold pressing mechanisms 17; after the lithium battery is packaged on the first side through the first side packaging conveyor line 1, the carrier 4 is transferred by the transfer mechanism 3 to the second side packaging conveyor line 2 to continue packaging the second side of the lithium battery. The process of packaging the first side and the second side is the same. When the first side is packaged with double folding packaging, the second side is also packaged with double folding packaging; when the first side is packaged with single folding packaging, the second side is also packaged with single folding packaging.

[0066] Between the hot pressing mechanism 12 and the hot melt glue dispensing mechanism 13, there are also provided a CCD photo-taking and glue dispensing position mechanism 18, a UV glue dispensing mechanism 19, a CCD size inspection mechanism 20 and a curing mechanism 5;

[0067] When the lithium battery is packaged with double folding edges, the CCD camera to find the glue position mechanism 18, the UV glue mechanism 19, the CCD size inspection mechanism 20 and the curing mechanism 5 are in a stopped standby state; when the lithium battery is packaged with double folding edges, it is not necessary to apply UV glue to the edge of the lithium battery film. The packaging is performed by folding the corners and folding the edges twice, and only one application of hot melt glue is required.

[0068] When the lithium battery is packaged with a single folding edge, the folding mechanism 8, the edge pressing mechanism 9, the CCD folding angle inspection mechanism 10, the 180-degree folding mechanism 11 and the hot edge pressing mechanism 12 are in a stopped standby state; when the lithium battery is packaged with a single folding edge, UV glue is required to seal the edge of the lithium battery's film, and 180-degree folding and folding operations are not required.

[0069] The precise positioning mechanism 6, the trimming mechanism 7, the hot melt adhesive dispensing mechanism 13, the CCD hot melt adhesive inspection mechanism 14, the 90-degree folding mechanism 15, the two hot pressing mechanisms 16 and the two cold pressing mechanisms 17 are common mechanisms for single-folding packaging and double-folding packaging.

[0070] The carrier 4 includes an upper splint assembly 41 and a lower splint assembly 42. The lower splint assembly 42 is controlled to be lifted by the rotation of an eccentric wheel 43. The upper splint assembly 41 and the lower splint assembly 42 are connected by a snap-fit structure. When the upper splint assembly 41 and the lower splint assembly 42 are disconnected, the upper splint assembly 41 can be pulled upward. The use of the eccentric wheel 43 to lift the lower splint assembly 42 can reduce the lifting force and achieve a labor-saving effect. In addition, the rotation control of the eccentric wheel makes it easy to control the lifting. The upper splint assembly 41 is connected to the lower splint assembly by a snap-fit structure. When disconnected, it can be pulled upward to widen the distance between the upper and lower splints, making it convenient to clean the upper and lower splints. After cleaning, the upper splint assembly can be pressed down to connect the upper and lower splint assemblies, thereby achieving the purpose of convenient cleaning. The lower clamping plate assembly 42 comprises two corresponding lower side plates 421. Lower linear guides 422 are located on the corresponding sides of the two lower side plates 421. These guides are connected to an intermediate plate 424 via a lower slider 423. The intermediate plate 424 is provided with a spring 425, which connects to a lower clamping plate 426. The intermediate plate 424 is located below the lower clamping plate 426. When the eccentric wheel 43 rotates to lift the intermediate plate 424, the lower clamping plate 426 follows. The bottoms of the two lower side plates 421 are connected by a base plate 427, and the eccentric wheel 43 is connected to the center of the base plate 427 via an eccentric wheel base 431. When the lower clamping plate 426 is lifted, the spring acts as a buffer, preventing damage to the battery caused by excessive clamping force and thus protecting the battery. The eccentric wheel 43 is provided with an extension arm 432, which is controlled by a lift control mechanism (not shown). The lift control mechanism pushes the extension arm 432, driving the rotation of the eccentric wheel 43. The rotation of the eccentric wheel 43 lifts the middle plate 424. The rise of the middle plate 424 drives the lower clamping plate 426 upward. When the lower clamping plate 426 and the upper clamping plate clamp the lithium battery, the lower clamping plate acts as a buffer to the clamping force. The upper ends of the two lower side plates 421 are respectively provided with a clamping block mounting groove 428. The clamping block mounting groove 428 is provided with a clamping block mounting seat 429. The middle portion of the clamping block mounting seat 429 is provided with a notch 420. The notch 420 is connected to the clamping block 4201 via an axle pin. The lower end of the clamping block 4201 is provided with a clamping block spring (not shown). The upper end of the clamping block 4201 is provided with two clamping arms 4202. When an external force presses the lower end of the clamping block 4201, the upper end of the clamping block 4201 opens outward, removing the tension restriction on the upper clamping plate assembly 41. After the upper and lower clamping plates are cleaned, an external force is applied to the upper clamping plate, which then slides down along the upper linear guide rails. The upper ends of the two clamping arms 4202 engage the clamping plates in the clamping slots 416, restricting the movement of the upper clamping plate assembly 41. The upper clamping plate assembly 41 includes two corresponding upper side plates 411. Upper linear guide rails 412 are provided on the corresponding sides of the two upper side plates 411. The two upper linear guide rails 412 connect the upper clamping plate 414 and the lifting plate 415 via upper sliders 413. The upper clamping plate 414 is located below the lifting plate 415.Two slots 416 are respectively provided at the lower ends of the two upper side plates 411 . A clamping plate (not shown) is respectively provided in the two slots 416 . The two clamping arms 4202 are respectively corresponding to one slot 416 and clamped into the clamping plate.

[0071] The transplanting mechanism 3 includes a transverse servo mechanism and a transplanting base plate. The transverse servo mechanism is arranged on the transplanting base plate. A carrier guide rail is provided on the transplanting base plate. The carrier guide rail is connected to the transplanting plate through a slider.
