Description

Technical Field

[0001] The present application relates to the field of stamping technology, and in particular to an explosion-proof membrane stamping device. Background Art

[0002] In the existing battery structure, after the battery cell is placed in the steel shell, a top cover needs to be placed on the steel shell. In the current production process of the top cover, a layer of explosion-proof membrane needs to be installed inside the top cover, wherein the bottom surface of the explosion-proof membrane is a rubber surface, and the explosion-proof membrane is subsequently glued to the top cover by hot melting. The existing technology is to transfer a strip of explosion-proof membrane material to a stamping device, and then stamp the explosion-proof membrane into shape. However, the existing stamping device will flip the material strip during the transmission process, resulting in the front and back of the explosion-proof membrane being reversed when the explosion-proof membrane is stamped into the top cover. If the rubber surface of the explosion-proof membrane faces upward, the explosion-proof membrane cannot be glued to the top cover during the subsequent hot melting, resulting in a batch of defective products.

[0013] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0014] Example

[0015] In order to solve the above technical problems, this embodiment provides an explosion-proof film punching device, such as Figure 1 As shown, it includes a mounting frame 10 and a reeling and unreeling assembly 20 arranged on the mounting frame 10. The reeling and unreeling assembly 20 is used to unreel and reel the strip-shaped explosion-proof film so that the explosion-proof film is transported and moved. A stamping assembly 40 is arranged on the conveying path of the explosion-proof film. A carrying fixture 50 is arranged below the stamping assembly 40. The carrying fixture 50 carries a top cover. When the explosion-proof film moves to the stamping assembly 40, the explosion-proof film is stamped into shape by the stamping assembly 40, and the explosion-proof film is pressed down into the top cover of the carrying fixture 50. A limit assembly 30 for limiting the flipping of the explosion-proof film is also arranged between the stamping assembly 40 and the reeling and unreeling assembly 20. The limit assembly 30 is provided to prevent the explosion-proof film from flipping during the movement process, thereby ensuring that the stamping direction of the explosion-proof film is accurate, thereby ensuring the quality of the finished product.

[0016] Specifically, the unwinding and reeling assembly 20 includes a discharge tray 21, a receiving tray 22, and a first driver 23 for driving the receiving tray 22 to rewind. The limit assembly 30 is located between the stamping assembly 40 and the receiving tray 22. The first driver 23 is a motor, and the receiving tray 22 is driven to rotate by the first driver 23. The explosion-proof film strip is discharged from the discharge tray 21, then stamped and formed by the stamping assembly 40, and then reeled by the receiving tray 22.

[0017] Furthermore, the limiting assembly 30 includes a rotating wheel 31 and a third driver 32 for driving the rotating wheel 31 to rotate. A pressure wheel 33 is arranged above the rotating wheel 31. The explosion-proof membrane passes between the rotating wheel 31 and the pressure wheel 33, and is clamped on the explosion-proof membrane material strip by the rotating wheel 31 and the pressure wheel 33. Then, the explosion-proof membrane material strip is flipped and limited during the movement to ensure that the stamping direction of the explosion-proof membrane is accurate.

[0018] Furthermore, in the above scheme, a guide assembly 60 for guiding the explosion-proof film is provided between the receiving tray 22 and the stamping assembly 40. The guide assembly 60 includes a first guide roller 61 and a second guide roller 62 which are sequentially arranged along the conveying path of the explosion-proof film. The explosion-proof film strip is guided by the first guide roller 61 and the second guide roller 62 in sequence before entering the stamping assembly 40, and then the explosion-proof film strip is further prevented from turning over by the guiding effect of the first guide roller 61 and the second guide roller 62, thereby ensuring the molding quality.

[0019] In order to realize the punching explosion-proof membrane, the punching assembly 40 includes a punching die 41 for the explosion-proof membrane to pass through, and a second driver 42 for driving the punching die 41 to press down the explosion-proof membrane. The second driver 42 can be a cylinder. The punching die 41 is pressed down by the second driver 42, and then the cutter inside the punching die 41 is pressed down to cut, so as to obtain an explosion-proof membrane of a preset shape. The supporting jig 50 is located below the punching die 41, and the supporting jig 50 is placed with a top cover, and then the punched explosion-proof membrane is pressed down into the top cover of the supporting jig 50, and then the top cover is transported to the next process by transporting the supporting jig 50.

[0020] Furthermore, a lifting driver 51 is connected to the bottom of the support jig 50, and the lifting driver 51 drives the support jig 50 to move closer to or away from the bottom of the stamping die 41. A through hole connected to the support jig 50 is provided at the bottom of the stamping die 41. The stamping die 41 stamps the explosion-proof film strip so that the explosion-proof film is lowered from the through hole of the stamping die 41 to the top cover of the support jig 50, thereby completing the assembly of the explosion-proof film in the top cover. Exemplarily, the lifting driver 51 can be a cylinder, and the lifting driver 51 drives the support jig 50 to rise and abut against the bottom of the stamping die 41. At this time, the through hole of the stamping die 41 corresponds to the position of the top cover of the support jig 50, thereby facilitating the assembly of the top cover in the top cover.

[0021] To summarize, the present application scheme arranges a reel-and-roll assembly on a mounting frame, and unwinds and reels the strip-shaped explosion-proof film through the reel-and-roll assembly, so that the explosion-proof film is transported and moved; a stamping assembly is arranged on the conveying path of the explosion-proof film, and a carrying jig is arranged below the stamping assembly, and the carrying jig carries a top cover. When the explosion-proof film moves to the stamping assembly, the explosion-proof film is stamped into shape by the stamping assembly, and the explosion-proof film is pressed down into the top cover of the carrying jig; a limit assembly for limiting the flipping of the explosion-proof film is also arranged between the stamping assembly and the reel-and-roll assembly. By arranging the limit assembly, the explosion-proof film is prevented from flipping during the movement process, thereby ensuring that the stamping direction of the explosion-proof film is accurate, thereby ensuring the quality of the finished product.

[0022] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
