Description

Technical Field

[0001] This invention relates to the field of powder pressure molding technology, and in particular to an automatic powder distribution station. Background Technology

[0002] High-energy power batteries, as core power sources, play a crucial role in aerospace and other fields. Powder-pressed electrodes, as a key component of high-energy power batteries, directly affect the battery's performance, safety, and lifespan. In the production process of powder-pressed electrodes, the powder application process is particularly important. Traditional powder application mainly relies on manual operation. During powder application, operators must first manually pour the powder into the mold cavity, then precisely adjust the depth of the mold cavity with one hand while smoothing the powder with the other, ensuring a flat surface and guaranteeing uniform thickness and stable quality of the subsequently pressed electrodes.

[0003] However, this traditional manual powder application process suffers from drawbacks such as high labor intensity, low efficiency, strong reliance on experience, and harsh working conditions for operators. Chinese invention patent CN201410023112.9 discloses an automatic powder application device that integrates a transmission mechanism, a powder application mechanism, and a vibration mechanism, avoiding the shortcomings of manual powder application and improving product quality. However, this device, which uses a moving mechanism to simultaneously apply powder, is unsuitable for round products and cannot achieve high-precision quantitative powder application. Chinese invention patent CN201910831479.6 discloses a powder applicator and cold-press forming machine that uses a scraper rod to rotate the scraper surface to level the powder, improving production efficiency. However, this device can only level annular surfaces, and the linear velocity of the scraper plate varies along its circumferential radius, making it impossible to guarantee uniformity of the scraped thickness. Furthermore, during the scraping process, the powder is easily compressed, piled up, and adheres to the scraper rod, making it unsuitable for high-precision quantitative powder application. Given the numerous problems with traditional powder application processes and existing technologies, how to achieve precision, efficiency, and stability in the powder application process for power batteries is an urgent issue that this application needs to address.

The first tray lifting mechanism 7, the second tray lifting mechanism 8, and the third tray lifting mechanism 9 are fixedly connected in the middle of the tray component 6; the lifting block 75 is provided with a guide angle 751 and a lifting plane 752, and a pin 76 is provided at one end of the lifting plane 752; the first tray lifting mechanism 7, the second tray lifting mechanism 8, and the third tray lifting mechanism 9 have the same structure; the lifting block 75 is used to lift and position the tray component 6; the rod motor 79 is used to provide the lifting movement of the lifting block 75, and at the same time, the rod motor 79 can perform acceleration and deceleration control to ensure the stability of the movement, thereby reducing the vibration of the tray component 6 when returning to the conveyor line 5 and avoiding damage to the powder spread in the mold 65; the guide angle 751 is used to guide the tray component 6; the lifting plane 752 is used to support the bottom of the lifted tray component 6; the pin 76 is used to position the tray component 6.

[0042] During the implementation of this invention, such as Figure 1-14 As shown, the specific operation steps are as follows:

[0043] First, after the mold 65 in the carrier tray component 6 has completed the quantitative filling of powder raw materials in the previous process, it is transported to this workstation via the conveyor line 5 for automatic powder distribution. Since the first carrier tray lifting mechanism 7, the second carrier tray lifting mechanism 8, and the third carrier tray lifting mechanism 9 have the same structure, the following explanation uses the first carrier tray lifting mechanism 7 as an example: When the carrier tray component 6 reaches the designated position, the rack of the rod motor 79 drives the second connecting plate 72 to move upward, thereby driving the two lifting blocks 75 to rise. The carrier tray component 6 is guided by the guide angle 751 to complete alignment, and then further precisely positioned by the pin 76, finally landing on the lifting plane 752. Next, the carrier tray component 6 continues to rise to the preset height, at which point the space below it can accommodate other carrier tray components 6 to pass through.

[0044] Once the carrier plate component 6 reaches the preset height, the electric cylinder module 235 drives the mold gripper 236 to move downwards to the gripping position, whereby the mold gripper 236 grips the mold 65. The electric cylinder module 235 then returns to its original position. Next, the fourth lead screw module 233 moves the mold 65 to directly above the rotating plate 2219. The electric cylinder module 235 then descends again, and the mold gripper 236 places the mold 65 on the rotating plate 2219. At this point, the bottom of the mold 65 is positioned within the limiting cylindrical cavity 22191, and the first positioning pin 2220 is inserted into the U-shaped groove 65111 of the positioning ear 6511 of the outer mold sleeve 651. Afterwards, the electric cylinder module 235 and the fourth lead screw module 233 return to their original positions.

[0045] Next, the third lead screw module 224 drives the rotating rod 2212 to move upward, causing the "T"-shaped hook block 22121 to insert into the strip groove formed by the first half-T-shaped groove 65211 and the second half-T-shaped groove 65212. The first servo motor 226 drives the rotating rod 2212 to rotate 90°, causing the "T"-shaped hook block 22121 to hook onto the inner mold core 652. Subsequently, the second lead screw module 214 drives the scraper plate 2112 to move downward until it contacts the upper surface of the mold 65, at which point the spring 2110 is slightly compressed. Then, the third lead screw module 224 drives the rotating rod 2212 to move upward, thereby pushing the inner mold core 652 to rise, making the cylindrical cavity for storing powder raw materials formed by the small cylinder 6522 and the small cylindrical cavity 6513 shallower. Next, the second lead screw module 214 drives the scraper plate 2112 to perform a transverse reciprocating motion, using the trapezoidal surface of the cavity 21121 to scrape the powder raw material transversely. Subsequently, the first servo motor 226 drives the rotating rod 2212 to rotate, which in turn drives the inner mold core 652 and the outer mold sleeve 651 to rotate to a set angle. The second lead screw module 214 then drives the scraper plate 2112 to perform a horizontal reciprocating motion, scraping the powder material horizontally. This process is repeated until the cylindrical cavity is filled with powder. Then, the third lead screw module 224 drives the rotating rod 2212 to pull the inner mold core 652 downward, deepening the cylindrical cavity, and repeats the above powder scraping process again until all the powder is scraped into the cylindrical cavity. During the powder scraping process, the air hammer 2113 generates high-frequency vibration, which disperses the powder that clumps together during the scraping process, and at the same time shakes off the powder that sticks to the surface of the cavity 21121.

[0046] After the powder scraping is completed, the second lead screw module 214 drives the scraper plate 2112 to reset, and the first servo motor 226 drives the rotating rod 2212 to rotate 90° in the opposite direction, so that the "T"-shaped hook block 22121 returns to its initial state. The mold gripper 236 picks up the mold 65 and places it back onto the support plate 61 of the first tray lifting mechanism 7. Subsequently, the rack of the rod motor 79 drives the second connecting plate 72 to move downward, thereby driving the tray component 6 to descend until the tray component 6 falls onto the conveyor line 5 and is conveyed by the conveyor line 5 to the next process.

[0047] During this process, the first powder dispensing mechanism 2, the second powder dispensing mechanism 3, and the third powder dispensing mechanism 4 respectively grasp the mold 65 in the tray component 6 at the first tray lifting mechanism 7, the second tray lifting mechanism 8, and the third tray lifting mechanism 9 to perform automatic powder dispensing operations. These three sets of mechanisms can be calibrated with formula parameters according to the production line cycle time, and can be operated individually or in combination according to the formula to achieve automatic powder dispensing function.
