Description

Technical Field

[0001] The utility model relates to the technical field of battery hot pressing, in particular to a uniform hot pressing device for new energy battery production. Background Technique

[0002] Hot pressing is a process of heating and pressing the formed slab at the same time to make a fiber board with certain mechanical strength and water resistance. The hot pressing in the battery production process is to hot press and shape the bare battery by setting reasonable time, temperature and pressure, and control the thickness of the bare battery to prevent the relative displacement of the positive and negative electrode plates;

[0003] The patent No. CN219321399U discloses a hot pressing device for new energy battery production, including a frame device for supporting and fixing. An extrusion device for uniformly heating and pressing down the new energy battery is arranged in the middle of the frame device. A sliding device for placing the new energy battery and stably moving is arranged below the extrusion device. A clamping device for clamping the new energy battery from both sides at the same time and reducing the downward pressure is arranged inside the sliding device. This device can reduce the downward pressure and avoid damaging the new energy battery due to the resistance of the spring during the downward pressing of the pressing block; through the setting of pushing the clamping device to clamp the battery during the downward pressing of the pressing block, manual operation of pressing is omitted, time is saved, and work efficiency is improved; the setting of heating the pressing block by the heating rod through the liquid can make the pressing block uniformly heated and improve the quality of the new energy battery. However, the following problems still exist in the actual use of this patent:

[0004] When placing the battery in the above device, it is necessary to manually place the independent battery into the placement groove, which is not conducive to integrating into the battery assembly line production. Moreover, since the external temperature of the battery after hot pressing is relatively high, the above device directly takes and transfers it by hand, which has potential safety hazards. At the same time, after the two sides of the battery are clamped, the spring is still in a telescopic state, so that the clamping stability of the battery is relatively low, and the vibration of the whole device during hot pressing will cause the connecting rod to have a short-distance displacement, affecting the stability of battery hot pressing.

[0038] Working principle: Before using this uniform hot pressing device for new energy battery production, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6 As shown in the figure, the battery is placed on the double-belt conveyor 104 and transported to the lower part of the placement groove. At this time, the hydraulic rod 226 is started to make the lifting block 202 push the battery upward and into the placement groove. Then, the first electric push rod 204 is started to make the expanding ring block 209 move and snap-fit with the lifting block 202, increasing the overall support received by the bottom of the battery, so that the pressure received by the battery during hot pressing is more uniform;

[0039] As the expanding ring block 209 moves, the stepped block 220 will drive the vertical plate 221 to move, and through the first spring 223, the sliding rod 222 will drive the push rod 210 to move, so that the clamping plate 211 clamps the battery.

[0040] And by rotating the rotating column 229, the second gear 228 drives the first gear 227 to rotate, so that the threaded sleeve 214 drives the second electric push rod 216 to move through the fixed block. Furthermore, when batteries of any size are in contact with the clamping plate 211, the clamping plate 218 can move to a position where it engages with the clamping ring 224 at this time, enabling the device to be applicable to batteries of various sizes;

[0041] After the hot pressing of the battery is completed, by lowering the hydraulic rod 226, the battery descends into the battery placement groove. After the battery passes through the induction probe 206, the hydraulic rod 226 stops. At the same time, cold air is directly blown onto the just-heated battery by means of the ventilation groove 205 and the ventilation pipe 225, so that the battery can be quickly cooled, facilitating subsequent processing;

[0042] Finally, after the hydraulic rod 226 is completely reset, the hot-pressed battery moves back onto the double-belt conveyor 104 and is transported away, enabling the device to be incorporated into the existing new energy battery production line, thereby increasing its practicality.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
