Description

Technical Field

[0001] This utility model relates to the field of sagger loading technology, specifically to a sagger supply device and a sagger loading machine. Background Technology

[0002] Currently, in the production of powder materials such as positive and negative electrode materials for lithium-ion batteries, the materials to be sintered must first be loaded into saggers before being sintered at high temperatures in a kiln. To ensure the consistency and quality of the sintered materials, there are high requirements for the loading speed and quantity. Based on this, a production line has been applied to the field of sagger loading technology. A production line, also known as an "assembly line," is a production method in industry. It is a streamlined batch production route that processes materials from their initial state through a series of production processes, including processing, transportation, assembly, and inspection, to achieve the desired product. By utilizing each unit to focus on a specific task, the goal of improving work efficiency is achieved.

[0003] In existing technologies for sagger loading production lines, a large number of devices are often required to handle specific tasks / processes, such as sagger loading, sagger conveying, and sagger output. After sagger loading, the production line needs to be transitioned to a specific environment for loading. This transition time is relatively long, and because an environmental transition is required for each loading operation, the sagger supply efficiency is low, making it difficult to meet the loading speed.

[0054] Example 1

[0055] like Figure 1-4 This embodiment provides a sagger supply device, which is a key piece of equipment for sagger conveying and adapting to the production environment in automated production processes. The overall structure of the sagger supply device adopts a modular design to achieve efficient transfer and environmental isolation of saggers in different production stages.

[0056] like Figure 1This sagger supply device includes: a frame 10, which serves as the supporting structure. A sagger inlet replacement chamber 14 is located on the frame 10. A first conveying mechanism 17 is located at the bottom of the sagger inlet replacement chamber 14, which is responsible for the initial receiving and positioning of the saggers. A loading replacement chamber 15 is used to convert the saggers before they are conveyed to the sagger inlet replacement chamber 14, adapting it to the production environment. The loading replacement chamber 15 is located on the frame 10 and connects to the sagger inlet replacement chamber 14. A second conveying mechanism 18 is located at the bottom of the loading replacement chamber 15, which is responsible for outputting the saggers after loading. Vacuum tubes 16 are installed on the sagger inlet replacement chamber 14 and the loading replacement chamber 15, allowing for vacuum evacuation of both chambers. Among them, a sealing door 21 is provided between the sagger inlet replacement chamber 14 and the loading replacement chamber 15, and the sagger inlet replacement chamber 14 is used to close the sagger inlet replacement chamber 14 and / or the loading replacement chamber 15. The sealing door 21 can connect the sagger inlet replacement chamber 14 and the loading replacement chamber 15, or it can be separated into an independent production environment unit. The specific implementation is as follows: The loading replacement chamber 15 has an environment conversion function. Before conveying saggers to the sagger inlet replacement chamber 14, it can be adjusted to a first production environment that is consistent with or basically consistent with the loading replacement chamber 15 (the parameters of the production environment, such as temperature, pressure, atmosphere, etc.). Then, the saggers are conveyed into the loading replacement chamber 15 via the first conveying mechanism 17. Subsequently, the sealing door 21 separates the sagger inlet replacement chamber 14 and the loading replacement chamber 15. The loading replacement chamber 15 performs production operations in the first production environment, and the sagger inlet replacement chamber 14 is converted to the second production environment and receives the next sagger. Repeating the above process can ensure the process continuity of saggers during the cross-functional area (i.e., the sagger inlet replacement chamber 14 is used for sagger inlet, and the loading replacement chamber 15 is used for loading) conveying process.

[0057] like Figure 3 , 4 In one embodiment shown, the sealing door 21 includes: a frame 212; and a moving mechanism 213 disposed within the frame 212 and moving along a first direction. Figure 3 , 4The first direction of movement is vertical, meaning the moving mechanism 213 moves in a lifting motion. The moving mechanism 213 can drive the door panel 214 to move synchronously. The door panel 214 is movably connected to the side of the moving mechanism 213 via multiple hinge rods 2133. The door panel 214 is opposite to the passage openings of the inlet sagger replacement chamber 14 and the loading replacement chamber 15. The limiting member 216 is located at the bottom of the frame 212 and is used to stop the door panel 214 from moving downward. The multiple hinge rods 2133 can be distributed on the upper and lower sides and the left and right sides of the door panel 214 to provide sufficient support. When the door panel 214 moves synchronously with the moving mechanism 213 along the first direction to the position of the limiting member 216, the limiting member 216 prevents the door panel 214 from moving forward. At this time, the door panel 214 stops in the first direction, the moving mechanism 213 continues to move along the first direction and drives the hinge rod 2133 to deflect. The first end of the hinge rod 2133 is driven by the moving mechanism 213 to move downward, and the second end of the hinge rod 2133 deflects and pushes the door panel 214 connected to the second end toward the passage opening, squeezing and sealing the passage opening.

[0058] like Figure 3 , 4 In one embodiment shown, the sealing door 21 includes a moving drive mechanism 211; the moving drive mechanism 211 is used to drive the moving mechanism 213 to move along a first direction. The moving drive mechanism 211 includes push rods 2112; the push rods 2112 are located on both sides of the moving mechanism 213 and are arranged in pairs, preferably symmetrically to ensure smooth and stable movement of the moving mechanism 213; the first end of each push rod 2112 is connected to the moving mechanism 213, and the second end passes through the top frame of the frame 212 and forms a sliding fit with the top frame; a linear bearing can be installed on the top frame to cooperate with the push rod 2112. Further, the second ends of the paired push rods 2112 are connected to the same actuating rod 2111, and a second linear actuator is provided on the top frame. The actuating end of the second linear actuator is connected to the bottom of the actuating rod 2111, and the second linear actuator is used to push the actuating rod 2111 to drive the paired push rods 2112 to move synchronously up and down. Among them, the second end of the pair of push rods 2112 is synchronized through the action rod 2111. By pushing the action rod 2111, the pair of push rods 2112 are driven to lift and lower, thereby driving the overall displacement of the moving mechanism 213 and the door panel 214 assembly.

[0059] like Figure 3 , 4In one embodiment shown, the moving mechanism 213 includes: a connecting plate 2131; a support plate 2134 disposed on the connecting plate 2131 and arranged along a first direction; the support plate 2134 comprises multiple pieces spaced apart, preferably evenly arranged; a first connecting rod 2132 passes through the support plate 2134; the first end of the hinge rod 2133 is rotatably engaged with the first connecting rod 2132, and the first connecting rod 2132 provides a fulcrum for rotation of the hinge rod 2133. Preferably, a sufficient number of support plates 2134 are provided to provide sufficient strength support for the first connecting rod 2132 to pass through and lift the door panel 214. Preferably, two first connecting rods 2132 are provided, corresponding to the upper and lower sides of the door panel 214.

[0060] like Figure 3 , 4 In one embodiment shown, the side frame of the frame 212 is provided with a guide groove, which is used to guide the moving mechanism 213 to move along a first direction. Multiple support plates 2134 are fitted with second connecting rods 2135. The first end of the second connecting rod 2135 extends out of the support plate 2134 and is rotatably connected to a guide wheel 2136. The guide wheel 2136 cooperates with the guide groove to guide the moving mechanism 213 to move. The guide wheel 2136 and the guide groove are in a rolling fit to ensure the stability of the movement trajectory of the moving mechanism 213 and the door panel 214.

[0061] like Figure 4 In one embodiment shown, the limiting member 216 is provided with a limiting platform and a guide slope. The lower end of the guide slope is connected to the limiting platform, and the upper end of the guide slope is away from the door panel 214. The bottom of the door panel 214 is provided with rollers that cooperate with the limiting platform and the guide slope.

[0062] like Figure 1 , 2 In one embodiment shown, the sagger supply device includes a transition chamber 5. The transition chamber 5 is located at the junction of the sagger inlet replacement chamber 14 and the loading replacement chamber 15. The first end of the transition chamber 5 is connected to the sagger inlet replacement chamber 14, and the second end is connected to the loading replacement chamber 15. The transition chamber 5 serves as the connecting hub between the sagger inlet replacement chamber 14 and the loading replacement chamber 15, and its internal auxiliary conveying function can be integrated. Both the first conveying mechanism 17 and the second conveying mechanism 18 are roller conveyors, which are readily available and mature products. An auxiliary roller 19 is added to the bottom of the transition chamber 5, and the first conveying mechanism 17, the second conveying mechanism 18, and the auxiliary roller 19 are matched and connected to form a continuous sagger conveying surface. The auxiliary roller 19 assists in conveying the sagger between the first conveying mechanism 17 and the second conveying mechanism 18 through independent drive or passive transmission, eliminating the speed difference between the roller conveyors of the sagger inlet replacement chamber 14 and the loading replacement chamber 15, and ensuring the stability of the sagger during cross-regional transmission. In another embodiment, the auxiliary roller 19 is provided at the bottom of the bottom frame of the sealing door 21 to assist the crucible in passing through the sealing door 21.

[0063] In one embodiment, the door panel 214 of the sealing door 21 located at the junction of the inlet sagger replacement chamber 14 and the loading replacement chamber 15 is disposed in the transition chamber 5. There are several possible configurations for the door panel 214 of the sealing door 21: First, one sealing door 21 is provided, with the door panel 214 located near the entrance of the sagger replacement chamber 14. Driven by the moving mechanism 213, the door panel 214 can close the entrance of the sagger replacement chamber 14. Second, one sealing door 21 is provided, with the door panel 214 located near the entrance of the loading replacement chamber 15. Driven by the moving mechanism 213, the door panel 214 can close the entrance of the loading replacement chamber 15. Third, two sealing doors 21 are provided: one sealing door 21 has its door panel 214 located near the entrance of the sagger replacement chamber 14, which can close the entrance of the sagger replacement chamber 14 under the drive of its corresponding moving mechanism 213; the other sealing door 21 has its door panel 214 located near the entrance of the loading replacement chamber 15, which can also close the entrance of the loading replacement chamber 15 under the drive of its corresponding moving mechanism 213. Figure 1 , 2 The installation scheme for the central sealing door 21 adopts Scheme 2.

[0064] like Figure 4 In one embodiment shown, the sealing door 21 includes a counterweight 215; the counterweight 215 is disposed between the door panel 214 and the moving mechanism 213, and the counterweight 215 is used to counterweight the door panel 214 and / or the moving mechanism 213 when they move in a first direction; the counterweight 215 can be connected to the door panel 214 and / or the moving mechanism 213, and is used to optimize and control the mass distribution of the moving mechanism 213 and the door panel 214, so as to realize the dynamic balance and stable operation of the moving mechanism 213 driving the door panel 214.

[0065] like Figure 2 In one embodiment shown, the sealing door 21 includes a first sealing door 24, a second sealing door 22, and a third sealing door 23. The first sealing door 24 is located at the inlet end of the sagger replacement chamber 14 and is used to isolate the external environment. The second sealing door 22 is located between the sagger replacement chamber 14 and the loading replacement chamber 15, achieving dynamic isolation between the two functional areas. The door panel 214 of the second sealing door 22 is located in the transition chamber 5. A second linear actuator is located outside the transition chamber 5 and at the top of the transition chamber 5. A portion of the push rod 2112 passes through the top of the transition chamber 5 and connects to the actuating rod 2111 at the top of the transition chamber 5. A mechanical seal is provided at the junction of the push rod 2112 and the top of the transition chamber 5. The third sealing door 23 is located at the outlet end of the loading replacement chamber 15, ensuring the output of the sagger after loading.

[0066] like Figure 1In one embodiment shown, the top of the loading and displacing chamber 15 and the sagger loading and displacing chamber 14 are provided with a top cover 20, which is used to connect to other equipment. For example, the top cover 20 of the loading and displacing chamber 15 can be connected to the loading mechanism 13 to load the saggers in the loading and displacing chamber 15.

[0067] The sagger supply device of this utility model can separate the sagger inlet replacement chamber 14 and the loading replacement chamber 15 into independent production environment units through the cooperation of the first sealing door 24 and the second sealing door 22. After adjusting the production environment of the sagger inlet replacement chamber 14 to be consistent with that of the loading replacement chamber 15, the two are connected and the sagger is transported into the loading replacement chamber 15. Then, the second sealing door 22 separates the sagger inlet replacement chamber 14 and the loading replacement chamber 15 into independent production environment units, and the sagger inlet replacement chamber 14 and the loading replacement chamber 15 each perform different processes. For example: when the second sealing door 22 and the third sealing door 23 are closed, the loading and replacement chamber 15 is in a vacuum environment; the sagger enters the sagger replacement chamber 14 through the first sealing door 24, the first sealing door 24 is closed, and the sagger replacement chamber 14 is evacuated to match the loading and replacement chamber 15; the second sealing door 22 is opened, the sagger is fed into the loading and replacement chamber 15, the second sealing door 22 is closed, and the sagger performs the loading process in the loading and replacement chamber 15; the first sealing door 24 is opened, the next sagger is fed into the sagger replacement chamber 14, the first sealing door 24 is closed, and a vacuum is evacuated; at the same time as the next sagger is fed into the sagger replacement chamber 14, the loading and replacement chamber 15 is completed and output from the third sealing door 23, the third sealing door 23 is closed, and a vacuum is evacuated; then, the second sealing door 22 is opened, and the next sagger enters the loading and replacement chamber 15 from the sagger replacement chamber 14, and so on, continuously completing the sagger input, sagger loading, and sagger output. Of course, the third sealing door 23 mentioned above can be eliminated. After the sagger is loaded, it returns to the sagger replacement chamber 14 and is then output. After that, the sagger replacement chamber 14 sends the next sagger into it. Of course, this design has a lower production efficiency than the above scheme.

[0068] This sagger supply device functionally divides the sagger supply process by setting up an inlet sagger replacement chamber 14 and a loading replacement chamber 15. The inlet sagger replacement chamber 14 first receives saggers and replaces the production environment before connecting with the loading replacement chamber 15. The loading replacement chamber 15 first outputs saggers and replaces the production environment before connecting with the loading replacement chamber 15. Sealing doors 21 are set on the inlet sagger replacement chamber 14 and the loading replacement chamber 15 to achieve multi-level sealing. They can seal the inlet sagger replacement chamber 14 and the loading replacement chamber 15 individually or simultaneously, so as to realize the transformation of the production environment within the sealed inlet sagger replacement chamber 14 and the loading replacement chamber 15. This allows the production environment of the inlet sagger replacement chamber 14 and the loading replacement chamber 15 to be transformed to the target production environment in advance, thereby improving the speed of sagger supply and sagger loading and increasing production efficiency. In addition, the coordinated design of the guide mechanism on the sealing door 21 and the auxiliary roller 19 in the transition chamber 5 enables efficient and safe transport of the sagger in the automated production line, while meeting the environmental isolation requirements of different production stages.
