Description

Technical Field

[0001] The utility model relates to a lithium battery graphite material production device, in particular to an automatic graphitization furnace loading device. Background Art

[0002] Graphite is a material used for the negative electrode of lithium batteries. In the production of graphitized materials, there are two ways to load the furnace: one is to load the powder and crucible into the furnace, and the other is to isostatically press the powder into blocks before loading the furnace. Currently, graphitization furnaces are generally loaded with isostatically pressed blocks, and the loading method is manual. However, the ambient temperature near the loading area is as high as ≥40°C, and the dust is ≥pM10. The loading environment is poor and time-consuming. Furthermore, the dimensions of the graphitized block material are generally length (50cm) × width (25cm) × 15 (cm). Loading is labor-intensive, and manually loading a furnace takes 3-5 days. This results in extremely low work efficiency, resulting in low production efficiency and high costs. Utility Model Content

[0003] The purpose of the utility model is to provide a graphitization automatic furnace loading device which has a simple structure, is easy to use, improves the degree of automation, reduces labor intensity, and effectively improves production efficiency.

[0004] In order to achieve the above-mentioned purpose, the automatic graphitization furnace loading device provided by the utility model includes a connecting device, a first bracket, a transverse drive assembly, two transverse splints, a second bracket, a longitudinal drive assembly and two longitudinal splints, the first bracket is fixed to the second bracket and the first bracket is located above the second bracket; the connecting device is arranged on the first bracket; the transverse drive assembly is arranged on the first bracket and drives the two transverse splints to approach or move away from each other in the transverse direction; the longitudinal drive assembly is arranged on the second bracket and drives the two longitudinal splints to approach or move away from each other in the longitudinal direction; the transverse splint and the longitudinal splint extend respectively to the bottom of the second bracket.

[0005] Compared with the prior art, the present invention sets a transverse drive component on the first bracket, and uses the transverse drive component to drive two transverse clamping plates to achieve transverse clamping; and sets a longitudinal drive component on the second bracket, and uses the longitudinal drive component to drive two longitudinal clamping plates to achieve longitudinal clamping. The two transverse plates and the two longitudinal clamping plates form a large square area, so that multiple graphitized block materials can be clamped at one time. The structure is very simple. It only needs to control the transverse drive component and the longitudinal drive component to clamp. It is easy to use and is conducive to improving the degree of automation and improving the handling efficiency. In addition, by connecting the first bracket with the second bracket and setting a connecting device on the first bracket, the connecting device can be connected to the workshop's driving system or crane system, so that the entire furnace loading device can be automatically transferred with the driving system after clamping the graphitized block material. Therefore, there is no need for manual handling, which greatly reduces labor intensity, improves production efficiency, and thus reduces production costs.

[0006] Preferably, the transverse drive assembly includes a first hydraulic rod and a second hydraulic rod. The first hydraulic rod is mounted on the first bracket and its telescopic end is connected to one of the transverse clamping plates. The second hydraulic rod is mounted on the first bracket and its telescopic end is connected to the other transverse clamping plate. Using the first and second hydraulic rods to drive the movement of the two transverse clamping plates not only simplifies the structure but also facilitates control, reducing equipment costs.

[0007] Preferably, the transverse drive assembly is a double-ended hydraulic rod that moves in and out simultaneously, and the two telescopic ends are respectively connected to the two transverse clamping plates. This can simultaneously control the movement of the two transverse clamping plates and improve the consistency of their movement.

[0008] Specifically, there are two double-ended, simultaneous-in and simultaneous-out hydraulic rods, and the two rods are arranged parallel to each other. By providing two double-ended, simultaneous-in and simultaneous-out hydraulic rods, both ends of the same transverse clamping plate can be driven by the telescopic ends of the double-ended, simultaneous-in and simultaneous-out hydraulic rods, thereby ensuring that the force applied to the graphitized block material at each position of the transverse clamping plate is uniform, ensuring that the graphitized block material is subjected to force, and improving the stability of the clamping.

[0009] Preferably, the longitudinal drive assembly includes a third hydraulic rod and a fourth hydraulic rod. The third hydraulic rod is mounted on the second bracket and its telescopic end is connected to one of the longitudinal clamping plates. The fourth hydraulic rod is mounted on the second bracket and its telescopic end is connected to the other longitudinal clamping plate. Using the third and fourth hydraulic rods to drive the movement of the two longitudinal clamping plates not only simplifies the structure and facilitates control, reducing equipment costs.

[0010] Preferably, the longitudinal drive assembly is a double-ended hydraulic rod that moves in and out simultaneously, and the two telescopic ends are respectively connected to the two longitudinal clamping plates. This can simultaneously control the movement of the two longitudinal clamping plates and improve the consistency of their movement.

[0011] Specifically, the number of the dual-headed, simultaneous-in and simultaneous-out hydraulic rods is two, and the two rods are arranged parallel to each other. By providing two dual-headed, simultaneous-in and simultaneous-out hydraulic rods, both ends of the same longitudinal clamping plate can be driven by the telescopic ends of the dual-headed, simultaneous-in and simultaneous-out hydraulic rods, thereby ensuring that the longitudinal clamping plate exerts force on the graphitized block material at all positions, ensuring that the graphitized block material is evenly stressed, and improving the stability of the clamping.

[0012] Preferably, the graphitization automatic furnace loading device further includes a first slide and a second slide, wherein the first slide is arranged on the first bracket for transverse movement and is connected one-to-one with each telescopic end of the transverse drive assembly, and the transverse clamps are fixedly connected to the first slide; the second slide is arranged on the second bracket for longitudinal movement and is connected one-to-one with each telescopic end of the longitudinal drive assembly, and the longitudinal clamps are fixedly connected to the second slide. By providing the first slide and the second slide, the first slide and the second slide can guide the movement direction of the transverse clamp and the longitudinal clamp, thereby improving the stability and smoothness of the movement of the transverse clamp and the longitudinal clamp.

[0013] Preferably, the first and second brackets are both frame structures, with the transverse drive assembly disposed within the frame of the first bracket, and the longitudinal drive assembly disposed within the frame of the second bracket. This allows the transverse drive assembly and the longitudinal drive assembly to be concealed within the first and second brackets, respectively, making the overall structure more compact and smaller.

[0014] Preferably, the transverse splint and the longitudinal splint both include a connecting bracket and a fastening splint, the fastening splint is connected to the lower end of the connecting bracket, and the upper end of the connecting bracket is connected to the telescopic end of the corresponding driving assembly.

[0020] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0021] like Figure 1 、 Figure 2 and Figure 5 As shown, the automatic graphitization furnace loading device 100 disclosed in the present invention includes a connecting device 1, a first bracket 2, a transverse drive assembly 3, two transverse clamps 4, a second bracket 5, a longitudinal drive assembly 6, and two longitudinal clamps 7. The first bracket 2 is fixed to the second bracket 5 and the first bracket 2 is located above the second bracket 5. The first bracket 2 and the second bracket 5 are both square in structure, and when combined, they form a cross-shaped structure. The lower surface of the first bracket 2 is fixedly connected to the outer side of the second bracket 5 via a connecting member 8. The upper surface of the second bracket 5 is fixedly connected to the outer side of the first bracket 2 via a connecting member 8. The connecting device 1 is disposed in the middle of the upper surface of the first bracket 2. The central portion of the connecting device 1 is provided with a hanging portion 11, which is defined by a hanging hole 111. The hanging hole 111 can be quickly connected to the hook of the workshop's driving system for transfer. The two transverse clamps 4 are respectively arranged at opposite ends of the first bracket 2; the two longitudinal clamps 7 are respectively arranged at opposite ends of the second bracket 5. The transverse drive component 3 is arranged on the first bracket 2 and drives the two transverse splints 4 to move closer to or away from each other in the transverse direction; the longitudinal drive component 6 is arranged on the second bracket 5 and drives the two longitudinal splints 7 to move closer to or away from each other in the longitudinal direction; the transverse splint 4 and the longitudinal splint 7 extend respectively to the bottom of the second bracket 5, and the transverse splint 4 and the longitudinal splint 7 are located at the same horizontal height.

[0022] See also Figure 3 and Figure 4The transverse drive assembly 3 comprises a double-ended hydraulic rod 31 that moves in and out simultaneously, with its two telescopic ends respectively connected to the two transverse clamps 4. The double-ended hydraulic rod 31 is a hydraulic rod with two telescopic ends that can be simultaneously extended or retracted into the cylinder. The longitudinal drive assembly 6 comprises a double-ended hydraulic rod 61 that moves in and out simultaneously, with its two telescopic ends respectively connected to the two longitudinal clamps 7. By utilizing the hydraulic rod to drive the movement of the two transverse clamps 4 and the longitudinal clamps 7, not only is the structure simple but also control is easy, reducing the cost of the equipment. The use of a double-ended hydraulic rod can simultaneously control the movement between the two transverse clamps 4 and the two longitudinal clamps 7, improving the consistency of their movement. Specifically, the transverse drive assembly 3 comprises two double-ended hydraulic rods 31 that are arranged parallel to each other. The longitudinal drive assembly 6 comprises two double-ended hydraulic rods 61 that are arranged parallel to each other. During clamping, the two double-ended, simultaneous in-and-out hydraulic rods of the transverse drive assembly 3 operate simultaneously, causing the two transverse clamps 4 to move toward each other simultaneously, thereby clamping the graphitized block material in the transverse direction. Simultaneously, the two double-ended, simultaneous in-and-out hydraulic rods of the longitudinal drive assembly 6 operate simultaneously, causing the two longitudinal clamps 7 to move toward each other simultaneously, thereby clamping the graphitized block material in the longitudinal direction. By providing two double-ended, simultaneous in-and-out hydraulic rods, both ends of the same transverse clamp 4 and the same longitudinal clamp 7 can be driven by the telescopic ends of the double-ended, simultaneous in-and-out hydraulic rods, thereby ensuring that the force applied to the graphitized block material by each position of the transverse clamp 4 and the longitudinal clamp 7 is uniform, ensuring that the force applied to the graphitized block material is uniform, and improving the stability of the clamping.

[0023] In another embodiment, the transverse drive assembly 3 may include a first hydraulic rod and a second hydraulic rod, wherein the first hydraulic rod is arranged on the first bracket 2 and the telescopic end is connected to one of the transverse splints 4, and the second hydraulic rod is arranged on the first bracket 2 and the telescopic end is connected to the other transverse splint 4. The first hydraulic rod and the second hydraulic rod are arranged in parallel with each other, or they may be arranged crosswise. The longitudinal drive assembly 6 includes a third hydraulic rod and a fourth hydraulic rod, wherein the third hydraulic rod is arranged on the second bracket 5 and the telescopic end is connected to one of the longitudinal splints 7, and the fourth hydraulic rod is arranged on the second bracket 5 and the telescopic end is connected to the other longitudinal splint 7. The third hydraulic rod and the fourth hydraulic rod are arranged in parallel with each other, or they may be arranged crosswise. In this way, the function and effect of clamping can also be achieved.

[0024] For example Figure 1 、 Figure 3 and Figure 4As shown, the graphitization automatic furnace loading device 100 also includes a first slide 9 and a second slide 110. The first slide 9 is arranged on the first bracket 2 for transverse movement and is respectively connected to the telescopic ends of the transverse drive assembly 3 in a one-to-one correspondence, and the transverse clamps 4 are respectively fixedly connected to the first slides 9. Specifically, the number of the first slides 9 is two, and the two first slides 9 are respectively located at opposite ends inside the first bracket 2; one of the first slides 9 is connected to one of the telescopic ends of the two double-headed hydraulic rods; and the other first slide 9 is connected to the other telescopic end of the two double-headed hydraulic rods. The second slide 110 is arranged on the second bracket 5 for longitudinal movement and is respectively connected to the telescopic ends of the longitudinal drive assembly 6 in a one-to-one correspondence, and the longitudinal clamps 7 are respectively fixedly connected to the second slides 110. Specifically, there are two second slides 110, each located at opposite ends of the second bracket 5. One of the second slides 110 is connected to one of the telescopic ends of the two double-ended simultaneous in-and-out hydraulic rods, while the other second slide 110 is connected to the other telescopic end of the two double-ended simultaneous in-and-out hydraulic rods. By providing the first slide 9 and the second slide 110, the first slide 9 and the second slide 110 can guide the movement direction of the transverse clamping plate 4 and the longitudinal clamping plate 7, thereby improving the stability and smoothness of the movement of the transverse clamping plate 4 and the longitudinal clamping plate 7.

[0025] See also Figure 3 and Figure 4 The first bracket 2 and the second bracket 5 are both frame structures, and the transverse drive assembly 3 is arranged in the frame of the first bracket 2. Specifically, on the first bracket 2, the two opposite inner side walls of the long frame of the frame structure are provided with sliding grooves (not shown in the figure), and the two ends of the first slide 9 are respectively slidably arranged on the sliding grooves on each side, and the first slide 9 is connected to the telescopic ends on the same side of the two double-headed hydraulic rods that enter and exit at the same time, and the same transverse splint 4 is arranged on the first slide 9. Similarly, the longitudinal drive assembly 6 is arranged in the frame of the second bracket 5. On the second bracket 5, the two opposite inner side walls of the long frame of the frame structure are provided with sliding grooves, and the two ends of the second slide 110 are respectively slidably arranged on the sliding grooves on each side, and the second slide 110 is connected to the telescopic ends on the same side of the two double-headed hydraulic rods that enter and exit at the same time, and the same longitudinal splint 7 is arranged on the second slide 110. In this way, the transverse drive assembly 3 and the longitudinal drive assembly 6 can be hidden in the first bracket 2 and the second bracket 5 respectively, thereby making the overall structure more compact and smaller in size.

[0026] See also Figure 3 and Figure 4The structures of the transverse clamping plate 4 and the longitudinal clamping plate 7 are identical. The structure of the transverse clamping plate 4 will be described below as an example. Both the transverse clamping plate 4 and the longitudinal clamping plate 7 include a connecting bracket 41 / 71 and a fastening clamping plate 42 / 72. The fastening clamping plate 42 / 72 is connected to the lower end of the connecting bracket 41 / 71. The upper end of the connecting bracket 41 of the transverse clamping plate 4 is connected to the first slide 9; the upper end of the connecting bracket 72 of the longitudinal clamping plate 7 is connected to the second slide 110. Furthermore, the clamping surface of the fastening clamping plate 42 / 72 is provided with a buffer rubber layer to reduce damage to the surface of the graphitized block material.

[0027] Compared with the prior art, the present invention sets a transverse drive component 3 on the first bracket 2, and uses the transverse drive component 3 to drive two transverse clamps 4 to achieve transverse clamping; and sets a longitudinal drive component 6 on the second bracket 5, and uses the longitudinal drive component 6 to drive two longitudinal clamps 7 to achieve longitudinal clamping. The two transverse plates and the two longitudinal clamps 7 form a large square area, so that multiple graphitized block materials can be clamped at one time. The structure is very simple. It only needs to control the transverse drive component 3 and the longitudinal drive component 6 to clamp. It is easy to use and is conducive to improving the degree of automation and improving the handling efficiency. In addition, by connecting the first bracket 2 with the second bracket 5, and setting a connecting device 1 on the first bracket 2, the connecting device 1 can be connected to the workshop's driving system or crane system, so that the entire furnace loading device can be automatically transferred with the driving system after clamping the graphitized block material. Therefore, there is no need for manual handling, which greatly reduces labor intensity, improves production efficiency, and thus reduces production costs.

[0028] The structure of the double-headed hydraulic rods with simultaneous entry and exit involved in the automatic graphitization furnace loading device 100 of the present invention is well known to those skilled in the art and will not be described in detail here.

[0029] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
