Description

Technical Field

[0001] The invention relates to the field of tunnel kiln equipment, in particular to an automatic loading and sucking production line for a tunnel kiln of negative electrode materials. Background Art

[0002] The artificial negative electrode material carbonization tunnel kiln is a baking equipment for artificial negative electrode materials. Its main function is to heat the granulated negative electrode materials at high temperature in the tunnel kiln to effectively reduce the volatile matter of the negative electrode materials and increase the filling rate of the artificial graphite negative electrode materials in the graphitization furnace.

[0003] According to a patent document with the existing publication number CN117367107A, a new energy negative electrode material carbonization energy-saving tunnel kiln is disclosed, which includes a kiln body, and the kiln body includes a firing section and a preheating section and a cooling section respectively arranged at both ends of the firing section. In the field of traditional industrial production, especially in the negative electrode material industry, the tunnel kiln is a commonly used firing equipment. For the link of crucible (sagger) loading, the early technology was not automated enough and could only be completed by manual or semi-automatic equipment. Since the material after the kiln cannot be cooled quickly, the temperature is high, the dust is large, and it is impossible to achieve rapid suction, the loading operation, and the production efficiency are low. Manual loading of tunnel kiln crucibles has the following disadvantages:

[0004] 1. Low efficiency and slow manual loading speed. Compared with automatic loading and suction equipment, less work is completed per unit time, which will affect the progress of the entire production process and cannot meet the needs of large-scale and high-efficiency production.

[0005] 2. Unstable quality. Manual loading may result in inconsistent loading amounts each time due to factors such as operator fatigue and differences in skill levels. For example, when loading powdered materials, it is difficult to accurately control the weight of each pot, which may affect the stability of product quality. It is difficult to ensure the uniformity of material distribution in the dry pot. If the loading is uneven, the material will be heated unevenly during the tunnel kiln firing process, and the final product may be partially over-burned or under-burned.

[0006] 3. The labor intensity is high, and operators need to perform repeated physical labor for a long time, such as carrying materials, loading materials into dry pots, etc. For example, when loading heavy block materials, frequent bending and raising hands can easily make workers tired and may cause occupational diseases.

[0007] 4. High safety risk. The working environment temperature around the tunnel kiln is high. Operators are easily exposed to high temperature during manual loading, which may cause burns. Some materials may have dust, pungent odor or toxicity. If the protection is not appropriate during manual loading, it may cause damage to the respiratory tract and skin of the operator.

While the third movable frame 52 moves forward and backward, the third connecting frame 56 moves left and right to complete the capping process. When capping, the suction cup on the third connecting frame 56 rises to the upper position. If the upstream and downstream permissions are both true, the capping stepper performs reciprocating motion to convey the kiln car 221 forward until the kiln car 221 is in place, and the positioning device is actuated to fix the kiln car 221 in the working position. After the car 221 is in place, the camera is moved to the top of the corresponding crucible 222, and a camera command is given after it stops. After receiving the camera command, the visual system takes a photo and transmits the correction data of the current crucible 222 to the capping manipulator. The capping manipulator moves to the top of the waiting position of the crucible cover on the conveying roller, and the suction cup descends and rises under the action of vacuum. The capping manipulator moves the suction cup to the top of the current crucible 222 according to the corrected coordinates. After the suction cup descends into place, the vacuum is released, the crucible cover is released, and the suction cup rises. The above action is repeated for the next crucible. The crucible cover conveying roller is divided into 4 groups, which automatically transports the crucible cover in the cover removal area to the cover installation area. The first and second groups of combined movements are used to queue the crucible covers, and the third and fourth groups of combined movements are used to dismantle the crucible covers. A positioning device is configured at the tail of the conveying roller. In order to ensure the precise alignment of the suction cup and the center of the cover, a visual system is configured to accurately locate the crucible cover position of the kiln car. The cover removal and lifting are controlled by a servo motor. After the whole car has completed the cover removal, the cover removal stepper sends the kiln car to the suction standby position.

[0047] Then, the suction stepper transfers the kiln car at the suction standby position to the suction working position. The unloading area is equipped with a double shield suction manipulator and a suction mechanism 10. The suction manipulator and the suction mechanism 10 are two sets of shield suction devices that work simultaneously to unload the materials of all crucibles on the kiln car through the vacuum suction system in turn. The suction manipulator and the suction mechanism 10 can be used at the same time or separately. When the suction manipulator is in use, the suction port at the bottom of the positioning seat on the suction manipulator completes the suction of a single crucible 222, and the suction mechanism 10 can complete the synchronous suction of multiple crucibles 222. In order to ensure that the shield cutter head is accurately aligned with the crucible 222, each set of shield cutter heads is equipped with a set of visual system for precise positioning. The kiln car 2221 and the crucible 222 are located. The visual system is mainly composed of an industrial camera, an industrial lens, a light source, a positive pressure dust cover, a light source controller, a visual controller and a display. Each crucible is photographed according to the theoretical coordinates to obtain the actual position coordinates of the crucible and transmit them to the motion controller via the IP bus. The two shield suction devices are designed for full stations. If one of the shield suction devices fails, the other shield suction device can also complete the whole car suction work. Each negative pressure pipeline of the vacuum suction system is equipped with a pipe crusher and a water cooling tank to crush and cool the materials. After the whole car suction is completed, the suction stepper sends the kiln car 221 to the manual cleaning standby position;

[0048] The hydraulic stepper in the manual cleaning area transfers the kiln car 221 to the manual cleaning workstation and the crucible 222 maintenance workstation. This workstation is equipped with a vacuum suction system and a manual operation platform for manually cleaning the residual materials in the crucible 222, cleaning the debris on the kiln car 221, and replacing the damaged crucible 222. After the kiln car 221 is cleaned, the hydraulic stepper sends the kiln car 221 to the loading standby position, and the loading stepper transfers the loading standby position to the loading workstation. When the loading stepper is in use, the second power mechanism 34 drives the second differential 33 to rotate, the second differential 33 drives the second transmission rod to rotate, and the second transmission rod drives the second limit block 36 on the second movable seat 35 to push the kiln car 221 to move. The connecting plate 37 and the guide plate 39 cooperate to increase the moving distance of the kiln car 221, so that the kiln car 221 enters the suction area. The loading area is equipped with a double-headed loading manipulator for loading operations, and each manipulator is equipped with 2 sets of spiral degassing charging devices. Two sets of spiral degassing and charging devices work simultaneously to load materials into all crucibles 222 on the kiln car in turn, and the materials are transported from the outlet of the loading buffer warehouse 1 to the loading manipulator buffer warehouse 2 through the vacuum suction system. The vacuum suction warehouse and the buffer warehouse 2 are connected by a sealed sleeve. The buffer warehouse 2 detects the material level through 3 sets of tuning fork level meters. In order to ensure that the charging port is accurately aligned with the crucible 222, each set of spiral degassing and charging devices is equipped with a visual system to accurately locate the position of the crucible 222 of the kiln car. The degassing device configured in the charging device cooperates with the spiral feeding mechanism to ensure that the feeding is dense. During charging, the spiral speed and the rising speed move in conjunction, and the ratio is adjustable. After the whole car is loaded, the loading stepper sends the kiln car 21 to the cover loading standby position. The stepper is driven by a servo motor and chain drag transmission. The locking device is driven by a cylinder. The locking device and the damping devices installed on both sides of the kiln car prevent the kiln car from sliding due to inertia. The matching reflective photoelectric switch accurately locates the working position of the kiln car.

[0049] The capping stepper transfers the kiln car 221 at the capping standby position to the capping working position. The capping robot automatically transfers the crucible cover on the conveyor roller to the corresponding crucible 222 of the kiln car. In order to ensure the accurate alignment of the cover and the crucible 222, a set of visual system is configured to accurately locate the positions of the kiln car 221 and the crucible 222. The capping lifting is controlled by a servo motor. After the whole car is capped, the capping stepper sends the kiln car 221 to the buffer standby position and gives the downstream permission signal at the same time. The downstream operation equipment automatically transfers the kiln car 221 to the next working position. The feeding is carried out in sequence. Two sets of ton bag unpacking stations and one raw material buffer bin are configured on the feeding device. The ton bag unpacking station uses a single-arm crane to move the ton bag to the top of the feeding bin, and the C-shaped knife configured at the unpacking station breaks the bottom of the ton bag, and the materials are gravity-fed into the corresponding raw material bin. The whole process is closed for feeding to avoid dust. The materials in the raw material bin are transported to the loading robot buffer bin 2 through the vacuum suction system. Finally, the finished products are packaged. Two finished product buffer bins are configured in the unloading area, and a set of ton bag filling station is configured at the bottom of each finished bin, and each ton bag canning station is configured with a floor scale for measurement.
