Description

Technical Field

[0001] The invention relates to the field of sagger production, and in particular to sagger forming equipment and a sagger forming process method. Background Art

[0002] The production process of lithium battery materials requires high-temperature sintering in a kiln. During the sintering process, a sagger is used to load the lithium battery materials. Lithium battery materials are highly corrosive. After long-term use, the bottom of the sagger will be corroded by the lithium battery materials. The sagger needs to be replaced frequently, which undoubtedly increases production costs. In order to improve the corrosion resistance of the bottom of the sagger, a common method is to spray glaze on the bottom surface of the sagger. However, the glaze layer is also prone to detachment, and the service life of the sagger cannot be guaranteed. For this reason, a sagger has been designed, in which a corrosion-resistant layer is provided on the inner bottom surface of the sagger. The corrosion-resistant layer needs to be formed by layering the corrosion-resistant material and the blank before the sagger is formed.

DETAILED DESCRIPTION

[0039] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0040] The present invention relates to a sagger forming device, comprising a mobile material distribution mechanism 100, a material distribution mechanism 200, a blank pressing mechanism 300 and a translation drive mechanism 400. The saggers produced by the sagger forming device are as follows: Figure 5 As shown, the sagger has a rectangular pocket-shaped body with an opening facing upward, and a corrosion-resistant layer is provided on the bottom surface of the inner part of the body.

[0041] like Figure 1 As shown, the compacting mechanism 300 and the translation driving mechanism 400 are distributed left and right. Figure 3 As shown, the compacting mechanism 300 includes an upper mold assembly 310 and a lower mold assembly 320, which are arranged vertically. The upper mold assembly 310 has a pressing head, which is raised and lowered by a hydraulic system. The lower mold assembly 320 includes an inner mold core 321 and an outer mold frame 322. The outer mold frame 322 is arranged around the inner mold core 321 and can move up and down relative to the inner mold core 321. In this embodiment, the inner mold core 321 is fixed, and the outer mold frame 322 is raised and lowered by the hydraulic system. The upper end surface of the inner mold core 321 is flat, while the upper end surface of the outer mold frame 322 is flat. When the outer mold frame 322 is raised or lowered, the upper end surface of the outer mold frame 322 can be higher, lower, or flush with the upper end surface of the inner mold core 321. A mold cavity 323 is separated from the outer mold frame 322 and the inner mold core 321. When the outer mold frame 322 rises to a position higher than the inner mold core 321, the mold cavity 323 forms a sagger-shaped shape. The pressing head of the upper mold assembly 310 descends into the mold cavity 323 to press the material inside the mold cavity 323.

[0042] The mobile material distribution mechanism 100 and the material distribution mechanism 200 are installed on the translation drive mechanism 400. Figure 2As shown, the movable material distribution mechanism 100 includes a template 110 and a movable hopper 120. Template 110 can be a flat plate, positioned horizontally. A die opening 111 is defined in template 110, connecting the spaces above and below template 110. The movable hopper 120 is positioned above template 110, with its material distribution opening 121 facing the upper surface of template 110. As shown, the movable hopper 120 moves horizontally in a forward and backward direction relative to template 110. As the movable hopper 120 moves relative to template 110, its material distribution opening 121 remains in contact with the upper surface of template 110, with the upper surface of template 110 blocking the material distribution opening 121. The left-right lateral width of the material distribution opening 121 is greater than that of the die opening 111. When the mobile hopper 120 passes through the die opening 111, it loses its blocking function, and the material in the mobile hopper 120 falls into the die opening 111. The mobile material distribution mechanism 100 can be controlled to rise and fall relative to the translation drive mechanism 400, and the mobile hopper 120 and the die plate 110 rise and fall synchronously. Two mobile material distribution mechanisms 100 are mounted on the translation drive mechanism 400, with the two mobile material distribution mechanisms 100 being distributed on the left and right sides of the translation drive mechanism 400. The die openings 111 of the two mobile material distribution mechanisms 100 have different sizes. The horizontal area and opening shape of the first die opening 111 match the corrosion-resistant coating of the sagger, while the horizontal area and opening shape of the second die opening 111 match the bottom of the sagger body. That is, the area of ​​the second die opening 111 is larger than that of the first die opening 111, and the second die opening 111 can completely cover the first die opening 111. The batching mechanism 200 is located above the movable material distribution mechanism 100 , and is used to distribute corresponding materials to the two movable hoppers 120 .

[0043] During operation, the two movable material distribution mechanisms 100 are driven by the translation drive mechanism 400 to move leftward toward the direction of the blank pressing mechanism 300. Figure 3As shown, the first movable material distribution mechanism 100 enters the space between the upper mold assembly 310 and the lower mold assembly 320, while the second movable material distribution mechanism 100 remains outside the compacting mechanism 300. Initially, the outer mold frame 322 descends to a position below or flush with the inner mold core 321. The first movable material distribution mechanism 100 descends relative to the translation drive mechanism 400 until the lower surface of the corresponding mold plate 110 is flush with the upper end surface of the inner mold core 321. At this point, the lower surface of the mold plate 110 abuts the upper end surface of the inner mold core 321, and the die opening 111 is aligned with the upper end surface of the inner mold core 321. The horizontal area of ​​the die opening 111 is smaller than the upper end surface of the inner mold core 321. The die opening 111 and the upper end surface of the inner mold core 321 cooperate to form a distribution space for the corrosion-resistant layer. The mobile hopper 120 on the movable material distribution mechanism 100 moves relative to the template 110. When the distribution port 121 of the mobile hopper 120 passes the die opening 111, the corrosion-resistant material in the mobile hopper 120 falls into the distribution space, dropping material as it moves, and the corrosion-resistant material is distributed throughout the distribution space. The mobile hopper 120 reciprocates repeatedly relative to the template 110. During movement, the distribution port 121 scrapes away any corrosion-resistant material that protrudes above the top of the distribution space, ensuring that the material evenly fills the distribution space. The mobile hopper 120 returns to its original position, and the mobile material distribution mechanism 100 rises away from the lower mold assembly 320. The corrosion-resistant layer is then distributed on the upper end surface of the inner mold core 321. The thickness of the corrosion-resistant layer is determined by the thickness of the template 110 at the corresponding position of the die opening 111. The area and shape of the corrosion-resistant layer are directly determined by the area and shape of the die opening 111. Then the translation drive mechanism 400 drives the first movable material distribution mechanism 100 to continue to move to the left, the first movable material distribution mechanism 100 leaves the green compacting mechanism 300, and the second movable material distribution mechanism 100 enters the green compacting mechanism 300. Figure 4As shown, the lower mold assembly 320 is activated, and the outer mold frame 322 moves upward relative to the inner mold core 321. The height difference between the outer mold frame 322 and the inner mold core 321 forms a mold cavity 323 for forming the sagger body. The shape of the mold cavity 323 is the same as when the sagger is inverted. The second movable material distribution mechanism 100 descends, and the lower plate surface of the corresponding template 110 is attached to the upper end surface of the outer mold frame 322. The die opening 111 of the template 110 is the same size as the top opening of the mold cavity 323 and is aligned with the top opening of the mold cavity 323. The movable hopper 120 translates relative to the template 110, and the sagger blank in the movable hopper 120 falls into the mold cavity 323 through the die opening 111 to fill the mold cavity 323. The movable hopper 120 performs multiple reciprocating translations, and the blank that protrudes above the template 110 is scraped flat through the material distribution opening 121, so that the blank evenly fills the mold cavity 323. The mobile hopper 120 resets, the mobile material distribution mechanism 100 rises and leaves the lower die assembly 320, and then the translation drive mechanism 400 drives the two mobile material distribution mechanisms 100 to move rightward and completely away from the pressing mechanism 300. As the blank is filled, the blank covers the corrosion-resistant layer material. The upper die assembly 310 presses downward, and the pressing head presses into the die cavity 323, compacting the material therein and forming the original blank body of the sagger. The corrosion-resistant layer is also formed within the original blank body.

[0044] In some specific embodiments of the present invention, Figure 2 As shown, the translation drive mechanism 400 includes a fixed frame 410, a mobile frame 420, and a first drive group 430. The mobile frame 420 and the fixed frame 410 can be slidably connected via rails, rollers, or other means. The first drive group 430 can utilize, but is not limited to, a motor-driven belt, chain, gear, or other transmission mechanism. The first drive group 430 drives the mobile frame 420 to translate horizontally on the fixed frame 410. Two mobile material distribution mechanisms 100 are mounted on the mobile frame 420 in a sequentially arranged manner. The batching mechanism 200 is mounted on the fixed frame 410. The translation drive mechanism 400, the mobile material distribution mechanism 100, and the batching mechanism 200 are combined to enable integrated transport and use with different pressing mechanisms 300. Furthermore, an auxiliary guide rail 500 is mounted on the left side of the pressing mechanism 300 and is located along the moving path of the mobile frame 420. When the mobile frame 420 moves to the left toward the pressing mechanism 300, the left side of the mobile frame 420 can slide on the auxiliary guide rail 500. The mobile frame 420 uses the auxiliary guide rail 500 for leverage to ensure that the mobile frame 420 remains stable when moving to the left and extending out of the fixed frame 410.

[0045] In some specific embodiments of the present invention, Figure 1As shown, the batching mechanism 200 includes a first batching group 210 and a second batching group 220. The first batching group 210 provides corrosion-resistant material to one of the mobile hoppers 120. The first batching group 210 is equipped with a weighing device, which weighs the corrosion-resistant material and then quantitatively distributes it to the mobile hopper 120. The specific structures of the first batching group 210 and the second batching group 220 can be the same or different. In this embodiment, the first batching group 210 can use a two-stage feeding belt structure to drop the material, while the second batching group 220 can use a gate hopper structure to supply the material.

[0046] In some specific embodiments of the present invention, as shown in the figure, a connecting base 610 is connected to one side of the mobile hopper 120, and the mobile hopper 120 and the connecting base 610 are slidably connected. Specifically, the connecting base 610 may be provided with a vertical guide groove, and the mobile hopper 120 is slidably connected to this guide groove. This means that the connecting base 610 has no vertical support for the mobile hopper 120. The mobile hopper 120 is directly supported on the template 110. The mobile hopper 120 is raised and lowered relative to the connecting base 610 along with the template 110. The translation drive mechanism 400 is provided with a second drive group 600. The second drive group 600 may adopt a structure with a motor and a belt transmission. The belt is connected to the connecting base 610, and the connecting base 610 can be slidably connected to the mobile frame 420 of the translation drive mechanism 400 via a slide rail. The second drive group 600 drags the mobile hopper 120 through the connecting base 610 to slide and translate on the template 110. Furthermore, the template 110 and the translation drive mechanism 400 are connected via a lift cylinder cover. The lift cylinders 700 can be fixed to the mobile frame 420. Four lift cylinders 700 are located at the four corners of the template 110. The drive ends of the lift cylinders 700 face upward to support the template 110, driving the template 110 to rise and fall.

[0047] Further, such as Figure 2 As shown, the material dispensing opening 121 is rectangular and may include a grille. Rubber scraper strips 122 are positioned around the opening 121, affixing to the upper surface of the template 110. When the movable hopper 120 translates relative to the template 110, the rubber scraper strips 122 close the opening 121, scraping away material from the upper surface of the template 110 and preventing it from scattering. During the dispensing process, when the rubber scraper strips 122 pass through the die opening 111, they also scrape away any material that protrudes above the die opening 111.

[0048] In some specific embodiments of the present invention, Figure 4As shown, the lower mold assembly 320 also includes an ejection frame 324. The ejection frame 324 surrounds the inner mold core 321 and can be driven by a hydraulic system to rise and fall relative to the inner mold core 321. Specifically, the ejection frame 324 is located between the inner mold core 321 and the outer mold frame 322. The top of the ejection frame 324 serves as the bottom of the mold cavity 323, while the inner sidewalls of the outer mold block and the outer sidewalls of the inner mold core 321 serve as the sidewalls of the mold cavity 323. The height of the ejection frame 324 determines the depth of the mold cavity 323, thereby controlling the height of the sagger. When the pressing head of the upper mold assembly 310 presses the blank, the ejection frame 324 is lifted upward by the hydraulic system to compact the blank around the sagger. After the blank is pressed, the ejection frame 324 can continue to rise, pushing the blank out of the mold cavity 323, thereby removing the blank from the mold.

[0049] The present invention also relates to a sagger forming process method, which uses the above-mentioned sagger forming equipment and at least comprises the following steps:

[0050] S1 batching: the batching mechanism 200 is used to configure corrosion-resistant material for one of the movable hoppers 120 and sagger body material for the other movable hopper 120;

[0051] S2 Corrosion-resistant layer feeding: The mobile feeding mechanism 100 equipped with the corrosion-resistant material moves into the blank pressing mechanism 300. The mobile feeding mechanism 100 descends so that the corresponding template 110 is attached to the upper end surface of the inner mold core 321. The die opening 111 and the upper end surface of the inner mold core 321 form a feeding space. When the mobile hopper 120 moves horizontally relative to the template 110, the corrosion-resistant material falls into the feeding space to form a corrosion-resistant layer. The corrosion-resistant layer is then scraped flat using the feeding opening 121 of the mobile hopper 120.

[0052] S3: After the movable distribution mechanism 100 in S2 completes the distribution of the corrosion-resistant layer, the movable distribution mechanism 100 rises and leaves the inner mold core 321, and then the movable distribution mechanism 100 as a whole moves horizontally away from the blank pressing mechanism 300;

[0053] S4: Forming the mold cavity 323: The outer mold frame 322 rises relative to the inner mold core 321, and a mold cavity 323 for molding the sagger body is formed between the outer mold frame 322 and the inner mold core 321;

[0054] S5 sagger body feeding: The mobile feeding mechanism 100 equipped with the sagger body material enters the green compacting mechanism 300, the mobile feeding mechanism 100 descends, the template 110 is attached to the upper end surface of the outer mold frame 322, the die opening 111 is aligned with the upper opening of the mold cavity 323, the mobile hopper 120 moves horizontally, and feeds the material into the mold cavity 323. When the mobile hopper 120 moves horizontally, the material on the top of the mold cavity 323 is scraped flat through the feeding opening 121. After the feeding is completed, the mobile hopper 120 rises and moves horizontally away from the green compacting mechanism 300;

[0055] S6: The upper mold assembly 310 descends, and the pressing head of the upper mold assembly 310 extends into the mold cavity 323, and cooperates with the mold cavity 323 to press the sagger body to form a green body;

[0056] S7 demoulding: After the green body is pressed, the green body is lifted upward and demoulded by the top green body structure in the lower mold assembly 320;

[0057] S8: After the blank is demoulded, it is taken out manually or by a blank removal device to complete unloading.

[0058] Furthermore, before step S2 , the upper end surface of the inner mold core 321 is coated with a mold release liquid; after the mold cavity 323 is formed in step S4 , the mold release liquid is coated on the inner wall of the mold cavity 323 .
