[0026] See also Figure 1 to Figure 8 In an embodiment of the present invention, a new energy battery upper cover blister forming device includes: a frame structure 1, a lifting assembly, a pumping mechanism and a power assembly, which can make the sealing plug 26 perform a lifting action after the blister is completed to deliver compressed air to the air guide 201, so as to lift the blister placed on the lower mold 2 to prevent the blister from sticking to the lower mold 2, and facilitate manual removal of the blister, and the compressed air flows between the lower mold 2 and the blister, which can cool the blister again to a certain extent, as follows: The frame structure 1 is provided with a lower mold 2 and an upper mold 3, and the lower mold 2 is provided with a plurality of air guide ports 201; The power assembly is arranged on the frame structure 1 and connected to the lifting assembly and the pulling assembly, and the power assembly can alternately drive the lifting assembly and the pulling assembly to move; The power assembly includes a connecting plate 7 mounted on the frame structure 1, a motor 8 is mounted on the connecting plate 7, and an output shaft of the motor 8 is connected to a Maltese cross movement structure arranged on the connecting plate 7; The Maltese cross movement structure includes a driving wheel 9 rotatably mounted on the link plate 7, the driving wheel 9 is adapted to a first driven wheel 10 and a second driven wheel 15 rotatably mounted on the link plate 7, and when the driving wheel 9 rotates, the first driven wheel 10 and the second driven wheel 15 can rotate alternately; When in use, after the raw material is placed on the lower mold 2, the motor 8 is controlled to work, and the motor 8 will drive the driving wheel 9 connected to its output shaft to rotate, wherein, when the driving wheel 9 cooperates with the first driven wheel 10, the first driven wheel 10 will be driven to rotate, and the second driven wheel 15 will be locked, and when the first driven wheel 10 rotates, the lifting assembly can drive the upper mold 3 to perform a lifting action, and when the upper mold 3 is attached to the lower mold 2, the blister operation is performed, and after the blister is completed, the upper mold 3 will move upward to reset; When the driving wheel 9 cooperates with the second driven wheel 15, the second driven wheel 15 will rotate. At this time, the first driven wheel 10 is in a locked state, thereby ensuring the position stability of the upper mold 3 when the second driven wheel 15 moves, and at the same time maximizing the gap between the upper mold 3 and the lower mold 2, making it more convenient to place raw materials and take out blister blanks.

[0027] Through the above arrangement, when the motor 8 is working, the first driven wheel 10 and the second driven wheel 15 can rotate alternately, so that the load of the motor 8 can be more balanced, and when the first driven wheel 10 and the second driven wheel 15 switch the rotation state, the locking state will also switch, so that when the second driven wheel 15 is working, the position state between the upper mold 3 and the lower mold 2 is more stable, and at the same time, the gap between the upper mold 3 and the lower mold 2 is maximized, making the process of placing raw materials and taking out blister blanks more convenient.

[0028] See also Figure 3~Figure 5 , the lifting assembly is arranged on the frame structure 1 and connected to the upper mold 3, and the lifting assembly can drive the upper mold 3 to move relative to the lower mold 2; The lifting assembly includes two transmission wheels 12 rotatably mounted on the connecting plate 7, a transmission belt 13 is sleeved between the two transmission wheels 12, and a rotating shaft of one of the transmission wheels 12 is connected to the first driven wheel 10 through a belt 11; The lifting assembly further includes a slider 5 connected to the upper mold 3 via a connector 4, the slider 5 is slidably connected to a first slide groove 101 provided on the frame structure 1, and the slider 5 is connected to the transmission belt 13 via a fitting structure, the fitting structure includes a fitting portion 6 connected to the slider 5, and a horizontal groove is formed on the fitting portion 6; The interlocking structure further includes an interlocking wheel 14 rotatably mounted on the transmission belt 13 , and the interlocking wheel 14 can roll in the horizontal groove.

[0029] When the first driven wheel 10 rotates, it will drive one of the transmission wheels 12 to work through the belt 11. At this time, the transmission belt 13 sleeved between the two transmission wheels 12 will work, and make the interlocking wheel 14 follow the movement of the transmission belt 13. The interlocking wheel 14 cooperates with the interlocking part 6 to realize the lifting of the slider 5, and drive the upper mold 3 to lift. Among them, the transmission belt 13 can be regarded as consisting of two circumferential ends and two straight ends. When the interlocking wheel 14 moves along the circumferential end, the interlocking wheel 14 can move along the length direction of the horizontal groove.

[0030] It is worth noting that within one rotation cycle of the first driven wheel 10 , the engaging wheel 14 can follow the transmission belt 13 to perform a lifting action and reset.

[0031] See also Figure 6~Figure 8 The air pump mechanism is connected to the air guide port 201, and the air pump mechanism includes a lifting component and a compression component. The lifting component cooperates with the compression component to deliver compressed air toward the air guide port 201; The compression assembly includes a sealed cylinder 24 mounted on the frame structure 1, and two one-way valves are arranged on the sealed cylinder 24, one of which is connected to the air guide port 201 through a conduit 29; A sealing plug 26 is sealingly and slidably installed in the sealing cylinder 24, and a connecting rod 25 perpendicular to the sealing plug 26 is arranged on the sealing plug 26, and the connecting rod 25 penetrates the sealing cylinder 24 and is slidably arranged; The connecting rod 25 is provided with a second spring 27, and one end of the second spring 27 away from the connecting rod 25 is connected to the sealing cylinder 24; The lifting assembly includes: a spiral transmission structure, a transverse rod 20 and a trigger member 23 .

[0032] The spiral transmission structure is arranged on the connecting plate 7, and the spiral transmission structure is connected to the second driven wheel 15 through a bevel gear set 16; The spiral transmission structure comprises a rotating shaft 17 rotatably mounted on the connecting plate 7, a closed groove 1701 is provided on the rotating shaft 17, and a sliding sleeve 18 is slidably sleeved on the rotating shaft 17, and a protrusion 1801 adapted to the closed groove 1701 is provided on the inner wall of the sliding sleeve 18; The sliding sleeve 18 is connected with a connecting rod 19, the connecting rod 19 is slidably connected with a second sliding groove 701 provided on the connecting plate 7, and one end of the connecting rod 19 away from the sliding sleeve 18 is slidably connected with the transverse rod 20; The transverse rod 20 is elastically connected to the spiral transmission structure, and the spiral transmission structure can drive the transverse rod 20 to move in the vertical direction, and the transverse rod 20 is adapted to the second convex shaft 28 connected to the connecting rod 25; One end of the transverse rod 20 is provided with an inclined surface 2001, and the other end is provided with two limiting portions 2002 adapted to the connecting rod 19; The transverse rod 20 is connected to a first spring 22, and the other end of the first spring 22 is connected to the connecting rod 19; The trigger member 23 is connected to the connecting plate 7 , and can cause the transverse rod 20 to be laterally displaced after the transverse rod 20 rises to a predetermined position. The trigger member 23 is in a triangular structure, and is adapted to a first protruding shaft 21 rotatably mounted on the transverse rod 20 .

[0033] When the second driven wheel 15 is working, the rotating shaft 17 will rotate one circle. At this time, the protrusion 1801 cooperates with the closed groove 1701, so that the connecting rod 19 can perform a lifting action. When the connecting rod 19 moves upward, it can drive the transverse rod 20 to move upward. At this time, the transverse rod 20 abuts against the second convex shaft 28, and the sealing plug 26 can be driven to move upward through the connecting rod 25. At this time, negative pressure is formed in the sealing cylinder 24 and the second spring 27 is stretched, so that the external air can be sucked into the sealing cylinder 24. In the cylinder body 24, when the transverse rod 20 rises to the end of the stroke, the first cam 21 will abut against the trigger member 23, and the two cooperate to enable the transverse rod 20 to move laterally, thereby being misaligned with the second cam 28, so that the first spring 22 is stretched. In this state, the second spring 27 releases elastic potential energy, causing the sealing plug 26 to move in the opposite direction and compress the air in the sealing cylinder body 24. After being compressed, the air enters the air guide port 201 to lift the blister on the lower mold 2, making it easier for workers to take the blister.

[0034] When the transverse rod 20 moves downward, the inclined surface 2001 on the transverse rod 20 will abut against the second cam 28, causing the transverse rod 20 to move horizontally again until the transverse rod 20 moves to the lower part of the second cam 28, and then the transverse rod 20 is reset, so that when the transverse rod 20 moves upward next time, it can drive the sealing plug 26 to perform the above action.

[0035] Through the above arrangement, after the blister is completed, the sealing plug 26 can perform a lifting action to deliver compressed air to the air guide port 201, thereby lifting the blister placed on the lower mold 2 to prevent the blister from sticking to the lower mold 2, making it easier to manually take out the blister, and the compressed air flows between the lower mold 2 and the blister, which can cool the blister again to a certain extent.

[0036] As an embodiment of the present invention, a method for producing a new energy battery cover using the device is also proposed, comprising the following steps: Step 1: Place the raw material flat on the lower mold 2, and then heat the raw material to soften it; Step 2: Control the motor 8 to work, and the lifting assembly moves, driving the upper mold 3 to move toward the lower mold 2 until the upper mold 3 and the lower mold 2 are tightly pressed together, and then the blister is performed; Step 3: The lifting assembly continues to move to separate the upper mold 3 from the lower mold 2; Step 4: The air pumping mechanism is activated to pump out the compressed air from the air guide port 201 to lift up the blister; Step 5: Manually remove the blister pieces, and then repeat the above steps 1 to 5 to achieve continuous blister operation.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
