Description

Technical Field

[0001] The present invention relates to the technical field of lithium ion negative electrode material packaging, in particular to lithium ion negative electrode material packaging equipment. Background Art

[0002] When producing lithium-ion negative electrode materials, the mixed and ground powder needs to be heated and dried. The most common material heating container in the current production process is the sagger. In the heating line, the powdered lithium-ion negative electrode material needs to be placed in the sagger first. This process is called loading.

[0003] In the prior art, when using a bowl loading machine to load bowls, the saggers need to be transported to the bottom of the bowl loading tube through a conveying device. In order to reduce dust emission and the impact on the electronic components in the bowl loading machine, a lower pressure plate is generally provided at the bottom of the bowl loading tube. When loading bowls, the bottom end surface of the lower pressure plate generally needs to be located inside the sagger. After the sagger is in place, the sagger is raised or the bowl loading tube is lowered, and then the material is loaded into the sagger through the bowl loading tube, and then the lower pressure plate is used to flatten it. However, in actual operation, as shown in the attached figure, Figure 15 As shown, the general filling tube is arranged above the center of the sagger 8. When the powdered material 9 is poured in, the accumulation amount of the material 9 in the middle of the sagger 8 will be significantly greater than the accumulation amount at the edge, so that the cross-section of the position occupied by the material 9 in the sagger 8 is conical. Sometimes, even when the lower pressing plate has not yet descended into the sagger 8, the material 9 has already accumulated too high in the middle of the sagger 8. Since the sagger 8 is generally loaded with material 9 that is almost full in actual production, in order to avoid the material 9 accumulated in the middle from clogging the filling tube, it is necessary to flatten the material 9 at least once by the lower pressing plate during the filling process, thereby reducing production efficiency. Summary of the Invention

[0004] In view of the above-mentioned defects, the present invention provides a lithium-ion negative electrode material loading device, which does not require additional material flattening operation during the process of loading the material into the sagger, thereby improving production efficiency.

[0016] Furthermore, the positioning mechanism further includes a pair of first brackets and a pair of second brackets, each first linear mechanism is respectively arranged on the first bracket, and each second linear mechanism is respectively arranged on the second bracket.

[0017] Furthermore, the lifting mechanism includes a fourth linear mechanism arranged vertically, and a U-shaped plate is provided at the upper end of the output shaft thereof. When the U-shaped plate is raised, both vertical sides thereof are passed between the rollers of the roller conveyor.

In this way, in the process of loading the materials into the sagger, there is no need for additional material flattening operation, but only needs to be flattened once a sagger is loaded, which can improve production efficiency.

[0025] 2. Multiple sagger loading units are set up in the outer box, which can simultaneously transport multiple saggers into the outer box. After the loading is completed synchronously, these saggers are transported out of the outer box, further improving production efficiency.

The lifting mechanism 4 includes a vertically arranged fourth linear mechanism 41, and a U-shaped plate 42 is provided at the upper end of its output shaft. When the U-shaped plate 42 is raised, one vertical edge thereof passes through the gap between the two rollers of the roller conveyor 2 and then contacts the bottom end surface of the sagger 8. The other vertical edge also passes through the gap between the two rollers of the roller conveyor 2 and then contacts the bottom end surface of the sagger 8.

[0051] like Figures 2 to 5 、 Figure 7 、 Figure 8 、 Figure 11 、 Figure 12 As shown, the inner box 5 is arranged above the roller conveyor 2. Specifically, the inner box 5 is arranged above the loading position of the sagger 8. A through hole 51 is opened on the upper end surface of the inner box 5, and a narrow portion 52 is extended from the lower end of the inner box 5. The lower end of the narrow portion 52 is opened. An opening is opened. When the lifting mechanism 4 lifts the sagger 8, the four inner side surfaces of the sagger 8 are respectively fitted with the four outer side surfaces of the narrow portion 52. Therefore, all the above-mentioned loading positions refer to the position on the roller conveyor 2 directly below the narrow portion 52. A folding groove 53 is provided at the lower part of one end face of the box 5, and the folding groove 53 extends from the outer side face of the inner box 5 to the bottom of the narrow part 52. The inner side face of the folding groove 53 is in a three-fold line shape, including two vertical sides and a horizontal side provided between the vertical sides. A transverse groove 54 is provided at the other end face of the inner box 5. Specifically, the transverse groove 54 is close to the lower side face of the side face of the inner box 5 where it is located. More specifically, a plurality of first hangers 55 are provided at the upper end of the inner box 5, and the upper ends of the first hangers 55 are fixed to the inner top wall of the outer box 1.

[0052] like Figures 2 to 5 、 Figure 9 As shown, the lower sealing mechanism 6 is provided at one end of the inner box 5, and is used to open and close the opening at the lower end of the narrow portion 52.

A horizontal plate 62 is provided at the lower end of the sliding end of the fifth linear mechanism 61, and a folding plate 63 matching the folding groove 53 is provided at one end of the horizontal plate 62. A pressing plate 64 matching the opening at the lower end of the narrow portion 52 is provided at the lower end of the folding plate 63.

[0053] like Figures 1 to 5 、 Figures 10 to 12 As shown, the mobile loading mechanism 7 includes a moving component provided at the other end of the inner box 5 and a loading component passed through the upper end surface of the inner box 5. The moving component includes a second hanger 711, a sixth linear mechanism 71 is provided at its lower end, and the sliding direction of its sliding end is parallel to the conveying direction of the roller conveyor 2. A seventh linear mechanism 72 is provided at the lower end of the sliding end of the sixth linear mechanism 71, and its output direction is perpendicular to the sliding direction of the sixth linear mechanism 71. An L-shaped frame 73 is provided at the lower end of one end of the seventh linear mechanism 72. The horizontal side of the L-shaped frame 73 extends to the outside of one end of the seventh linear mechanism 72, and a closing plate 74 is provided at the upper end of the vertical side. A shaft opening 741 is opened through the side of the closing plate 74. The output shaft of the seventh linear mechanism 72 is passed through the shaft opening 741 and a snap ring 75 is provided at one end of the output shaft. The ring 75 is arranged in the inner box 5. When the sixth linear mechanism 71 slides, the closing plate 74 and the output shaft of the seventh linear mechanism 72 always close the outer opening of the transverse groove 54. The bowl loading assembly includes a drop tube 76 connected to the feeding pipe 12 at the upper end. The drop tube 76 is fixedly penetrated at the feeding port. The lower end of the drop tube 76 is equipped with a first straight tube 77 fixedly penetrated in the through hole 51. The lower end of the first straight tube 77 is provided with a telescopic elbow 78. The lower end of the telescopic elbow 78 is provided with a second straight tube 79. The second straight tube 79 is fixedly penetrated in the clamping ring 75. The bottom end surface of the second straight tube 79 is located between the top and bottom ends of the narrow portion 52. The clamping ring 75 drives the second straight tube 79 to move within the range of the narrow portion 52 through the sixth linear mechanism 71 and the seventh linear mechanism 72. In this embodiment, as shown in FIG. Figure 14 In the top view shown, the arrow indicates the moving direction of the second straight tube 79 , which moves in a G-shape within the sagger 8 .

[0054] In this embodiment, the first linear mechanism 31 , the second linear mechanism 33 , the third linear mechanism 34 , the fourth linear mechanism 41 , and the seventh linear mechanism 72 all use single-axis linear cylinders, and the fifth linear mechanism 61 and the sixth linear mechanism 71 all use rodless linear cylinders.

[0055] As another embodiment, the inner box 5, the lower sealing mechanism 6, and the movable bowl loading mechanism 7 can be rotated 90° in any direction around the axis of the blanking tube 76. This arrangement achieves the same technical effect.

[0056] Working method:

[0057] First, multiple saggers 8 are placed at the starting point of the roller conveyor 2 according to the intervals between each loading unit, and then each sagger 8 is transported to the loading position by the roller conveyor 2. During transportation, the second linear mechanism 33 retracts the third linear mechanism 34 to prevent it from blocking the sagger 8 with the second push block 35. Since the position of the sagger 8 cannot be accurately located directly below the opening of the narrow portion 52 under normal circumstances, the positioning is performed by the positioning mechanism 3 after the roller conveyor 2 stops conveying. Specifically, for two side surfaces of the sagger 8, the first push block 32 is controlled by the first linear mechanism 31 to make contact. For the other two side surfaces of the sagger 8, the third linear mechanism 34 is first pushed out by the second linear mechanism 33, and then the second push block 35 is controlled by the third linear mechanism 34 to make contact. The sagger 8 is accurately located at the loading position by the two first push blocks 32 and the second push blocks 35 in contact with the sagger 8.

[0058] After the sagger 8 is positioned, the pressing plate 64 is opened by the fifth linear mechanism 61 , and then the U-shaped plate 42 is raised by the fourth linear mechanism 41 . The U-shaped plate 42 pushes the sagger 8 so that the narrow portion 52 extends into the sagger 8 .

[0059] Then, still with the above Figure 14 Taking the method shown as an example, the area inside the sagger 8 can be approximately divided into 9 blocks. From a top-down perspective, the sixth linear mechanism 71 and the seventh linear mechanism 72 are used to make the clamping ring 75 move the second straight pipe 79 to the upper right part, and then the material 9 is conveyed from the feeding pipe 12. The specific starting method can be that the storage mechanism connected to the feeding pipe 12 opens the valve to start the input of the material 9. The material 9 passes through the drop pipe 76, the first straight pipe 77, the telescopic elbow 78, and the second straight pipe 79 in sequence, and falls into the sagger 8 from the outlet of the second straight pipe 79, that is, the loading of the sagger begins. After the loading of the sagger begins, the second straight pipe 79 is moved so that the projection point of its axis in the sagger 8 moves from Figure 14 Starting from the upper right part of the top-down view shown, move in the direction of the arrow to the upper part, upper left part, left part, lower left part, lower part, lower right part, right part, and middle part of the top-down view in the sagger 8 in sequence, and when it moves to the middle part, it may be a state where the filling is about to be completed. This can better avoid the accumulation of material 9 in a single position, so that the material 9 is more evenly distributed in the sagger 8, and when a sufficient amount is loaded, the second straight tube 79 will not be blocked.

[0060] Then, the input of the material 9 is stopped, the sagger 8 is lowered by the lifting mechanism 4, the opening of the narrow portion 52 is closed by the pressing plate 64 through the fifth linear mechanism 61, and the sagger 8 is raised by the lifting mechanism 4. After the pressing plate 64 flattens the material 9, the sagger 8 is returned to the roller conveyor 2.

[0061] After each sagger 8 is filled and the material 9 is flattened, the roller conveyor 2 is started to convey the sagger 8 out of the outer box 1. Specifically, the end point of the roller conveyor 2 can be connected to the conveying device of the subsequent process of the lithium ion negative electrode material heating process line.

[0062] The above are only some of the embodiments listed in this application and are not intended to limit this application.
