Description

Technical Field

[0001] This invention relates to the field of lithium battery processing technology, and more specifically, to a processing apparatus for power lithium battery casings. Background Technology

[0002] In the current field of power lithium battery manufacturing, pouch batteries have received widespread attention in electric vehicles, high-end consumer electronics and energy storage systems due to their significant advantages such as high energy density, lightweight and safety performance superior to traditional metal-cased batteries. Unlike batteries that use steel or aluminum hard shells, pouch batteries are usually packaged in an aluminum-plastic film composed of a nylon layer, an aluminum foil layer and a polypropylene layer. The final encapsulation depends on a precise heat-sealing process. This process controls the heat-sealing head at specific temperatures, pressures and times to melt and fuse the polypropylene in the inner layer of the aluminum-plastic film, thereby forming a sealed encapsulation edge.

[0003] Traditional heat sealing processes typically employ an integral flat hot press head to heat and pressurize the large surface area of ​​the battery. However, due to the significant height difference between the battery cell body thickness and the outer packaging edge area, the packaging edge material needs to fill the stepped gap between the core edge and the packaging boundary during the pressurization process. This results in a longer material flow path and greater resistance in this area. At the same time, because the packaging edge area has a large exposed area and is in closer contact with the room temperature mold, its actual heat dissipation rate is much higher than that of the central area. This causes the material temperature in this area to be lower and its melt flow to be insufficient. Furthermore, it solidifies first during the cooling stage. Therefore, under uniform external pressure, the effective bonding pressure of the packaging edge area is significantly lower than that of the central area. To address this, we propose a power lithium battery casing processing device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the stamping part drives the central pressure ring to move downward. The central pressure ring contacts the battery surface and begins to apply pressure. As the pressure increases, the adjusting mechanism drives the movable sleeve to move downward. The movable sleeve drives the auxiliary sleeve to move downward through the slide rod. The auxiliary sleeve drives the edge ring to move downward. At this time, the edge ring can apply a higher pressure than the central area, thus forming a progressive pressure distribution from the outside to the inside with decreasing pressure compensation value, matching the heat from the outside to the inside of the sealing area.

[0016] 2. In this invention, by setting the edge rings as a flexible hinge array that can be actively deflected, and by mechanically linking them during the demolding stage, a wave-shaped peeling action is generated from the center to the edge. The multiple sets of edge rings are bent slightly to both sides in sequence like waves. The slight wave-shaped deformation destroys the simultaneous adhesion between the entire working surface and the sealing edge, allowing it to peel off in sections and in an orderly manner, avoiding adhesion and tearing.

[0017] 3. In this invention, the cleaning mechanism drives the auxiliary part at the bottom to rotate. At this time, the auxiliary part abuts against the upper end face of the pull rod. The pull rod drives the piston plate to move vertically, thereby driving the piston plate to squeeze the air in the auxiliary cavity, so that the gas from the air outlet is sprayed into the gap area to clean the sealing material in the gap area, thus ensuring the stability of the edge ring operation.

[0018] 4. In this invention, the overall hot press head is decomposed into a central pressure ring and a concentric edge ring, and an adjustment mechanism is used to enable the edge ring to apply a higher pressure than the central region in order to compensate for the natural attenuation of its pressure and heat.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0024] Example 1 further describes the power lithium battery casing processing device proposed in this invention, including a processing table 100, a drive seat 101 mounted on the upper surface of the processing table 100, a stamping part 102 fixedly connected to the bottom end of the drive seat 101, a cavity 103 formed in the stamping part 102, a movable rod 104 that moves vertically in the cavity 103, a central pressure ring 105 fixedly connected to the bottom end of the movable rod 104, and multiple sets of edge rings 106 sleeved on the outside of the central pressure ring 105, with two sets of edge rings 106 hinged together, the hinged part forming a gap area 107, and an adjustment mechanism 200 provided in the movable rod 104; Because the edge areas have a larger exposed area and dissipate heat quickly, their actual temperature is often lower than that of the center area. During the cooling and solidification stage, the edge areas solidify first due to their closer contact with the room-temperature mold. This device, by setting a central pressure ring 105 and multiple sets of edge rings 106, [further measures are needed to address this issue]. Figures 2 to 5 It is known that a cylindrical cavity 103 is formed inside the stamping part 102. A movable rod 104 moves vertically through the cavity 103. The central pressure ring 105 can drive the movable rod 104 to move in a certain direction. The central pressure ring 105 bears the basic heat sealing pressure and integrates a heating element inside, which is the main heat source. It is precisely fitted outside the central ring and can make slight axial movements. It has an independent heater inside, and the temperature is set slightly higher than that of the central ring. An adjustment mechanism 200 is provided inside the cavity 103. The adjustment mechanism 200 includes... The device includes a support member 201 disposed within the cavity 103, an offset member 202 disposed within the support member 201, and an abutment member 203 disposed within the cavity 103. The offset member 202 and the abutment member 203 cooperate to control the central pressure ring 105 and the edge ring 106. In specific use, the entire hot press head is decomposed into a central pressure ring 105 and a concentric edge ring 106. The adjustment mechanism 200 enables the edge ring 106 to apply a higher pressure than the central area to compensate for the natural attenuation of its pressure and heat. Because the high-temperature sealing material sometimes adheres to the working surface of the hot press head, causing tearing or deformation of the sealing edge during demolding, this device addresses this issue by providing a peeling mechanism 300 at the bottom of the stamping section 102. This peeling mechanism 300 includes a rotating component 301, with an adjusting component 302 at its bottom. The rotating component 301 and the adjusting component 302 work together to peel off the sealing material. Specifically, the edge ring 106 is designed as a flexible hinge array that can actively deflect, and during the demolding stage, it is mechanically linked to generate a... A wave-shaped peeling action from the center to the edge allows for segmented and sequential peeling, avoiding adhesion and tearing. When the peeling mechanism 300 is in use, the edge sealing material will sink into the gap area 107 where the hinge is located. The peeling mechanism 300 is equipped with a cleaning mechanism 400, which includes an auxiliary component 401. A fixing component 402 is provided on the outside of the stamping part 102, and an air vent 403 is provided inside the fixing component 402. The auxiliary component 401 and the air vent 403 work together to clean the edge sealing. Working principle: During use, the drive seat 101 drives the stamping part 102 to move downwards, which in turn drives the central pressure ring 105 to move downwards. The central pressure ring 105 contacts the battery surface and begins to apply pressure. As the pressure increases, the adjustment mechanism 200 then pushes the edge ring 106 downwards to apply maximum compensation pressure. This creates a gradual pressure distribution from the outside to the inside, with the pressure compensation value decreasing. This matches the heat and pressure attenuation gradient from the outside to the inside of the sealing area, allowing the edge ring 106 to apply higher pressure than the central area. Force is applied to compensate for the natural decay of pressure and heat. By designing the edge rings 106 as a flexible hinge array that can be actively deflected, and by mechanically linking them during the demolding stage, a wave-shaped peeling action is generated from the center to the edge. Multiple sets of edge rings 106 bend slightly to both sides like waves. Through the small wave-shaped deformation, the adhesion between the entire working surface and the sealing edge is destroyed, so that it is peeled off in sections and in order, avoiding adhesion and tearing. The gap area 107 where the hinge is located is cleaned by the cleaning mechanism 400.

[0025] Example 2 Based on Embodiment 1, the following technical features are added: The adjustment mechanism 200 includes a support member 201 disposed in the cavity 103, an offset member 202 disposed in the support member 201, and an abutment member 203 disposed in the cavity 103. The adjustment mechanism 200 enables the edge ring 106 to apply a higher pressure than the central area to compensate for the natural attenuation of its pressure and heat. The support member 201 includes a support cylinder 201a fixedly connected to the upper end face of the bottom of the cavity 103. The support cylinder 201a is provided with a central hole 201b. Openings 201c are provided on both sides of the outer wall of the central hole 201b. The movable rod 104 passes through the central hole 201b. A compression spring 201d is sleeved on the outer wall of the movable rod 104. Depend on Figures 2 to 6 It can be seen that the support cylinder 201a and the central hole 201b are cylindrical mechanisms. The central hole 201b is located inside the support cylinder 201a, and a square opening 201c is formed inside the central hole 201b. The movable rod 104 moves vertically through the central hole 201b. The movable rod 104 is fixedly connected to the inside of the movable sleeve 203a by a compression spring 201d. The compression spring 201d is a carbon spring, which has high strength and is easy to use. When the central pressure ring 105 contacts the battery surface, the central pressure ring 105 drives the movable rod 104 to move upward. The movable rod 104 drives the edge ring 106 to move downward, thereby pressing against the outer edge. In this way, the edge ring 106 can apply a higher pressure than the central area to compensate for the natural attenuation of its pressure and heat. The offset component 202 includes an inclined hole 202a provided in the movable rod 104. An inclined rod 202b is movably connected in the inclined hole 202a. An extrusion part 202c and an extrusion part 202d are fixedly connected to both sides of the outer wall of the inclined rod 202b. The two ends of the extrusion part 202c and the extrusion part 202d are slidably connected in the opening 201c. As shown in the figure, the inclined rod 202b is formed in the middle of the extrusion part 202c and the extrusion part 202d, forming a Z-shape. Depend on Figures 3 to 5 It is known that the movable rod 104 is provided with a long inclined hole 202a, and an inclined rod 202b is movably connected in the inclined hole 202a. Since the first extrusion part 202c and the second extrusion part 202d are slidably connected in the vertical opening 201c, and the upper and lower ends of the first extrusion part 202c and the second extrusion part 202d are slidably connected in the inner side of the opening 201c, under limited movement, the first extrusion part 202c and the second extrusion part 202d can only move in the horizontal direction. Therefore, when the first extrusion part 202c and the second extrusion part 202d move horizontally, they drive the movable sleeve 203a to move in the vertical direction. The abutting member 203 includes a movable sleeve 203a movably connected within the cavity 103. The movable sleeve 203a has a slot 203b. The upper end face of the compression spring 201d abuts against the inner wall of the slot 203b. Abutting portion one 203c and abutting portion two 203d are formed on both sides of the inner wall of the slot 203b. Pressing portions one 202c and two pressing portions two 202d correspondingly cooperate with the abutting portions one 203c and two abutting portions two 203d. Figures 3 to 7 It can be seen that the cavity 103 is slidably connected to a cylindrical movable sleeve 203a, and the inner side of the movable sleeve 203a is symmetrically fixedly connected to a compression part 1 202c and a compression part 202d, and the inclined surfaces of the compression part 1 202c and the compression part 202d cooperate with the inclined surfaces of the contact part 1 203c and the contact part 203d. Working principle: During use, the drive seat 101 drives the stamping part 102 to move downward, and the stamping part 102 drives the central pressure ring 105 to move downward. The central pressure ring 105 contacts the battery surface and begins to apply pressure. As the pressure increases, since the central pressure ring 105 is fixedly connected to the movable rod 104, and the movable rod 104 is connected to the inner wall of the movable sleeve 203a through the compression spring 201d, the central pressure ring 105 drives the movable rod 104 to move upward. Furthermore, the movable rod 104 is movably connected to an inclined plate through the inclined hole 202a. Under limited movement, the first extrusion part 202c and the second extrusion part 202d of rod 202b can only move horizontally. Therefore, when the first extrusion part 202c and the second extrusion part 202d move horizontally, they drive the movable sleeve 203a to move downward. The movable sleeve 203a drives the auxiliary sleeve 302c to move downward through the slide rod 302b. The auxiliary sleeve 302c drives the edge ring 106 to move downward. At this time, the edge ring 106 can apply a higher pressure than the central area to compensate for the natural decay of its pressure and heat.

[0026] Example 3 Based on Embodiment 2, the following technical features are added: It also includes a peeling mechanism 300, which is set on a rotating part 301 at the bottom of the stamping part 102. An adjusting part 302 is provided at the bottom of the rotating part 301. By designing the edge ring 106 as a flexible hinge array that can be actively deflected, and by mechanical linkage during the demolding stage, it generates a wave-shaped peeling action from the center to the edge, so that it peels in sections and in sequence, avoiding adhesion and tearing. It includes a sleeve 301a rotatably connected to the bottom of the stamping part 102 via a bearing. A through hole 301b is formed in the sleeve 301a. An arc groove 301c is provided in the through hole 301b. A positioning block 301d is fixedly connected to the outer wall of the movable rod 104. The positioning block 301d is slidably connected in the arc groove 301c. A circular plate 301e is fixedly connected to the outer wall of the sleeve 301a. Depend on Figures 3 to 8 It can be seen that the bottom end of the stamping part 102 is rotatably connected to a cylindrical sleeve 301a through a bearing. A cylindrical through hole 301b is formed inside the sleeve 301a, and an arc groove 301c is provided inside the through hole 301b. When the movable rod 104 moves vertically, its positioning block 301d is correspondingly slidably connected in the arc groove 301c, thereby driving the sleeve 301a to rotate. At the same time as the sleeve 301a operates, it drives the circular plate 301e to rotate synchronously. The adjusting component 302 includes a sliding opening 302a circumferentially located on the outside of the stamping part 102, a sliding rod 302b circumferentially fixedly connected to the outside of the movable sleeve 203a, an auxiliary sleeve 302c fixedly connected to the outside of multiple sliding rods 302b, an auxiliary opening 302d circumferentially located on the outside of the auxiliary sleeve 302c, and one side of the upper end face of the edge ring 106 is hinged to the lower end face of the auxiliary sleeve 302c, thereby limiting the position of the edge ring 106. A protruding plate 302e is fixedly connected to the outside of the circular plate 301e, a bearing seat 302f is fixedly connected to the bottom end of the protruding plate 302e, a universal ball 302g is fixedly connected to the upper end face of the edge ring 106, and a telescopic rod 302h is rotatably connected inside the bearing seat 302f and the universal ball 302g. When the protruding plate 302e rotates, it drives the edge ring 106 at the bottom end of the telescopic rod 302h to deflect. Depend on Figures 2 to 8 It can be seen that the sliding opening 302a has a long strip structure, and the outer side of the movable sleeve 203a is fixed with a sliding rod 302b in a circular shape. The sliding rod 302b moves vertically with the auxiliary sleeve 302c. When the movable rod 104 moves upward, the positioning block 301d on the outer side of the movable rod 104 is slidably connected in the arc groove 301c, thereby driving the sleeve 301a to rotate. At the same time as the sleeve 301a rotates, it drives the convex plate 302e on the circular plate 301e to move synchronously. Working principle: During use, when the movable rod 104 moves vertically, the positioning block 301d on the outer side of the movable rod 104 slides in the arc groove 301c, thereby driving the sleeve 301a to rotate. As the convex plate 302e on the sleeve 301a rotates, the convex plate 302e drives the edge ring 106 to deflect through the telescopic rod 302h. At this time, the edge ring 106 is set as a flexible hinge array that can be actively deflected. During the demolding stage, it generates a wave-shaped peeling action from the center to the edge through mechanical linkage. Multiple sets of edge rings 106 bend slightly to both sides like waves. Through the small wave-shaped deformation, the adhesion between the entire working surface and the sealing edge is destroyed, so that it is peeled off in sections and in order, avoiding adhesion and tearing.

[0027] Example 4 Based on Embodiment 3, the following technical features are added: a cleaning mechanism 400 is provided inside the peeling mechanism 300. The cleaning mechanism 400 includes an auxiliary component 401 provided on the upper end face of the rotating component 301, a fixing component 402 is provided on the outside of the stamping part 102, and an air outlet 403 is provided inside the fixing component 402. The auxiliary component 401 includes an auxiliary rod 401a that is circumferentially fixedly connected to the upper end face of the protrusion plate 302e. An annular strip 401b is fixedly connected to the upper end face of multiple sets of auxiliary rods 401a, and an auxiliary part 401c is circumferentially fixedly connected to the bottom end of the annular strip 401b. When the peeling mechanism 300 is in use, the sealing material will fall into the gap area 107 where the hinge is located. When this device is in use, the gap area 107 is cleaned by the air outlet 403, thereby cleaning the sealing material. As shown in the figure, when the convex plate 302e rotates, it drives the annular bar 401b at the upper end of the auxiliary rod 401a to rotate synchronously. At this time, the annular bar 401b drives multiple sets of auxiliary parts 401c to rotate synchronously. The fixing member 402 includes a fixing plate 402a circumferentially fixed to the outside of the stamping part 102. A fixing cylinder 402b is formed at the bottom end of the fixing plate 402a. An auxiliary cavity 402c is formed inside the fixing cylinder 402b. An annular strip 401b and an auxiliary part 401c are disposed in the auxiliary cavity 402c. Movable openings 402d are provided on both sides of the outer wall of the auxiliary cavity 402c. The air outlet member 403 includes a sealing plate 403a fixedly connected to the auxiliary cavity 402c. A pull rod 403b is connected internally. An auxiliary spring 403c is sleeved on the outer wall of the pull rod 403b. The auxiliary spring 403c is a carbon spring with high strength. The auxiliary spring 403c is fixedly connected to the upper end face of the sealing plate 403a. A piston plate 403d is fixedly connected to the bottom end of the pull rod 403b. The piston plate 403d is slidably connected in the auxiliary cavity 402c. An air outlet 403e is provided on the outer side of the auxiliary cavity 402c. The air outlet 403e corresponds to the gap area 107. Depend on Figures 1 to 8 It can be seen that a sealing plate 403a is fixedly connected inside the fixed cylinder 402b. A pull rod 403b is connected inside the sealing plate 403a through an auxiliary spring 403c. The pull rod 403b drives the piston plate 403d to move in the vertical direction. The piston plate 403d squeezes the air in the auxiliary cavity 402c, so that the gas from the air outlet 403e is sprayed into the gap area 107, thereby cleaning the sealing material in the gap area 107. Working principle: In actual use, the positioning block 301d on the outer side of the movable rod 104 is slidably connected in the arc groove 301c, thereby driving the sleeve 301a to rotate. As the convex plate 302e on the sleeve 301a rotates, the convex plate 302e drives the annular strip 401b on the upper end face of the auxiliary rod 401a to rotate. When the annular strip 401b rotates, it rotates in the movable opening 402d. The annular strip 401b drives the auxiliary part 401c at its bottom end to rotate. At this time, the auxiliary part 401c abuts against the upper end face of the pull rod 403b. At this time, the pull rod 403b drives the piston plate 403d to move vertically, thereby driving the piston plate 403d to squeeze the air in the auxiliary cavity 402c, so that the gas from the air outlet 403e is sprayed into the gap area 107, thereby cleaning the sealing material in the gap area 107, thus ensuring the stability of the edge ring 106 operation.
