Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature carbonization, in particular to an induction device and a high-temperature carbonization automatic production line. Background Art

[0002] High-temperature carbonization of lithium battery anode materials is a key step in preparing high-performance lithium-ion battery anode materials. This process primarily involves carbonizing the anode materials at high temperatures to improve their electrochemical performance, conductivity, mechanical stability, and cycle life.

[0003] In the relevant high-temperature carbonization automatic production line, there are a loading area, a buffer area and a heating area connected in sequence. The loading area is equipped with a pushing device, the buffer area is equipped with a conveying device, the input end of the conveying device is equipped with a gate, and the heating area is equipped with a kiln. The carbonized raw materials are contained in saggers. The pushing device can push multiple saggers into the conveying device of the buffer area at one time. At the same time, a laser sensor is configured on the conveying frame of the conveying device for sensing. When the sagger inside the buffer area reaches the sensing position, the laser sensor is blocked and the gate is controlled to close. The kiln buffer area sucks away the air and fills it with inert gas through gas replacement, and then transfers it to the kiln for high-temperature carbonization treatment.

[0004] The above scheme has the following defects: since the raw material powder in the sagger will overflow during the loading process, the transmission device and the sagger in the kiln buffer zone will be offset due to sliding friction, that is, the positions of multiple saggers will be offset and no longer on the same straight line. When the front sagger is sensed by the laser sensor and the gate falls, the rear sagger is still in the position where the gate falls. Therefore, the falling gate will accidentally damage the rear sagger. Figure 9 shown. Utility Model Content

[0034] The present invention provides a sensing device 100 .

[0035] See also Figures 1 to 3 In one embodiment of the present utility model, the sensing device 100 is applied to a high-temperature carbonization automatic production line 200. The high-temperature carbonization automatic production line 200 includes a conveyor frame 230 and a sagger 240. The sensing device 100 includes a detection switch 1, a rotating rod 2, a rotating shaft 3 and a contact member 4. The detection switch 1 is fixed to the conveyor frame 230. The rotating rod 2 can rotatably trigger the detection switch 1. The rotating shaft 3 is rotatably connected to the conveyor frame 230. The rotating rod 2 is fixedly connected to the rotating shaft 3 and rotates around the axis of the rotating shaft 3. The contact member 4 is fixed to the rotating shaft 3. The sagger 240 pushes the contact member 4 to drive the rotating shaft 3 to rotate.

[0036] In this embodiment, the sensing device 100 is provided at the input end of the conveying device in the buffer zone of the high-temperature carbonization automatic production line 200 and is located behind the gate. The conveyor frame 230 has two parallel side walls, and a conveying roller is provided between the two side walls for conveying the sagger. The rotating shaft 3 rotates and passes through between the two side walls, and partially extends to the outside of one side wall. The detection switch 1 and the rotating rod 2 are provided on the outside of the side wall of the conveyor frame 230, and the contact member 4 is provided on the inside of the side wall of the conveyor frame 230. Such a setting can prevent the sensing device 100 from interfering with the roller and affecting the conveying. The contact member 4 is provided between the two rollers, and the highest point of the contact member 4 is slightly higher than the highest point of the roller so as to contact the sagger and better trigger the detection switch 1.

[0037] Rotating rod 2 is arranged radially along rotating shaft 3, i.e., the rotating rod 2 and the rotating shaft 3 are axially perpendicular to each other. One end of rotating rod 2 is fixedly connected to rotating shaft 3, and the other end of rotating rod 2 triggers detection switch 1 as rotating shaft 3 rotates. Contact member 4 is fixedly connected to rotating shaft 3 and is shorter than rotating rod 2. Thus, contact member 4, rotating shaft 3, and rotating rod 2 form a lever system that rotates around rotating shaft 3, which can amplify the displacement of the sagger on conveyor frame 230 and improve the sensitivity of the detection device.

[0038] The detection switch 1 is a press-trigger switch. A pressure sensor or a displacement sensor is provided in the detection switch 1. The sensor is connected to the gate in the high-temperature carbonization automatic production line 200 to control the opening and closing of the gate. When there are always saggers 240 being transported on the conveyor rack near the gate of the high-temperature carbonization automatic production line 200, the contact member 4 is pushed by the sagger and is in a continuous triggering state. At this time, the gate is in an open state until all the saggers have passed through the sensing device 100. No sagger triggers the sensing device 100. At this time, the detection switch 1 rebounds to an untriggered state, and the gate falls down accordingly and closes the buffer zone. The air in the buffer zone is sucked away and filled with inert gas, and then it is conveyed to the kiln for high-temperature carbonization treatment. The mechanical sensing device 100 of this embodiment can detect the position of the sagger 240 by mechanical conduction, avoiding the failure of electronic sensors (for example, false detection of laser sensors in dusty environments) and the occurrence of production line failures.

[0039] The sensing device 100 of this embodiment is provided with a detection switch 1, a rotating rod 2, a rotating shaft 3 and a contact member 4. The detection switch 1 is fixed to the conveyor frame 230, the rotating rod 2 can rotatably trigger the detection switch 1, the rotating shaft 3 is rotatably connected to the conveyor frame 230, the rotating rod 2 is fixedly connected to the rotating shaft 3 and rotates around the axis of the rotating shaft 3, the contact member 4 is fixed to the rotating shaft 3, and the sagger 240 pushes the contact member 4 to drive the rotating shaft 3 to rotate. When there are objects to be sensed on the conveyor frame 230, the contact member 4 is continuously pushed, thereby driving the rotating shaft 3 and the rotating rod 2 to rotate and triggering the detection switch 1. After the last object to be sensed completely enters the conveyor device, the contact member 4 is no longer pushed, and the detection switch 1 is no longer triggered by the object to be sensed. At this time, the detection switch 1 controls the gate to close, thereby achieving the effect of preventing the gate from accidentally damaging the sagger 240.

[0040] Specifically, see Figures 4 and 5 In one embodiment of the present invention, the detection switch 1 includes a housing 11, a spring and a push rod 12. The push rod 12 is slidably arranged in the housing 11. The spring connects the push rod 12 and the housing 11. The push rod 12 is hinged to the end of the rotating rod 2 away from the rotating axis 3.

[0041] In this embodiment, a pressure sensor or a displacement sensor is provided in the shell 11 of the detection switch 1, and a guide member, such as a guide wall or a guide column, is also provided in the shell 11. A through hole matching the shape of the push rod 12 is provided on the shell 11. The push rod 12 is passed through the through hole and limited to the guide member, so that the push rod 12 can slide stably in the shell 11. A spring connects the push rod 12 and the shell 11 so that the push rod 12 rebounds to a specific position when no external force is applied and the sensor is in an untriggered state.

[0042] One end of the push rod 12 is hinged to the end of the rotating rod 2 away from the rotating axis 3. In this way, when the sagger 240 pushes the contact piece 4, the rotating rod 2 will rotate and push the push rod 12, thereby triggering the detection switch 1. That is, the linear motion of the sagger is first converted into the rotation of the rotating rod 2, and then converted into the linear motion of the push rod 12 after being amplified by the rotating rod 2. This design improves the sensitivity and reliability of the sensing device 100.

[0043] Further, see Figure 1 In one embodiment of the present invention, the sensing device 100 further includes a connector 5, one end of which is fixedly connected to the rotating shaft 3, the connector 5 gradually extends in a direction away from the rotating shaft 3, and the contact 4 is fixed to the end of the connector 5 away from the rotating shaft 3. In this embodiment, the sensing device 100 further includes a connector 5, one end of which is fixedly connected to the rotating shaft 3, and the other end of which gradually extends in a direction away from the rotating shaft 3 and fixes the contact 4. This design takes into account that when the rotating shaft 3 is installed on the conveyor frame 230, in order not to affect normal conveying, the highest point of the rotating shaft 3 is lower than the highest point of the roller shaft. In order to facilitate the contact between the contact 4 and the sagger, that is, in order to make the highest point of the contact 4 higher than the highest point of the roller shaft, a connector 5 is provided to connect the contact 4 to the rotating shaft 3. This structure also facilitates the assembly and replacement of the contact 4.

[0044] Further, see Figure 1 In one embodiment of the present invention, the contact member 4 is detachably connected to the end of the connector 5 that is away from the rotating shaft 3. In this embodiment, the contact member 4 is made of a wear-resistant material that has good friction with the sagger, such as metal or high-strength plastic. After long-term use, the contact member 4 will inevitably show some wear. Therefore, to facilitate replacement of the contact member 4, the contact member 4 and the connector 5 are detachably connected, for example, by means of a bolt, a key shaft, or a lock.

[0045] For further information, see Figure 1In one embodiment of the utility model, the connecting member 5 includes a first clamping block 51 and a second clamping block 52, the first clamping block 51 and the second clamping block 52 are fixedly connected, the rotating shaft 3 is fixedly clamped between the first clamping block 51 and the second clamping block 52, and the first clamping block 51 gradually extends in a direction away from the rotating shaft 3. In this embodiment, the connecting member 5 is composed of a first clamping block 51 and a second clamping block 52, and the two are fixedly connected by bolts. The rotating shaft 3 is fixedly clamped between the first clamping block 51 and the second clamping block 52 to ensure the stability of the rotating shaft 3. This design provides a strong clamping force, is suitable for high-load conveying environments, and improves the accuracy of the sensing device 100. The first clamping block 51 and the second clamping block 52 are made of high-strength alloy material to improve the durability and corrosion resistance of the connecting member 5. This material selection is particularly suitable for use in high temperature and corrosive environments. Anti-slip stripes are designed on the clamping points where the first clamping block 51 or the second clamping block 52 contacts the rotating shaft 3 to enhance the friction between the first clamping block 51 or the second clamping block 52 and the rotating shaft 3 to ensure the clamping force of the first clamping block 51 and the second clamping block 52.

[0046] Specifically, see Figure 1 In one embodiment of the present invention, the connector 5 further includes a first bolt 53. A first through-hole 51a is defined at one end of the first clamping block 51 proximate to the second clamping block 52, and a second through-hole 52a is defined at one end of the second clamping block 52 proximate to the first clamping block 51. The first bolt 53 sequentially passes through the first through-hole 51a and the second through-hole 52a, connecting the first clamping block 51 and the second clamping block 52. In this embodiment, the first bolt 53 employs a locking design, such as a locking washer or a self-locking nut, to prevent loosening due to vibration or impact. This design ensures the stability of the sensing device 100 during long-term operation or in harsh environments.

[0047] Specifically, see Figure 1 、 Figure 6 and Figure 7In one embodiment of the present invention, the contact member 4 is a roller, and the connecting member 5 further includes a second bolt 54. A third through-hole 51b is provided at the end of the first clamping block 51 away from the rotating shaft 3. The second bolt 54 extends through the third through-hole 51b and connects the roller to the first clamping block 51. In this embodiment, the contact member 4 is designed as a circular roller to ensure smooth contact between the sagger and the contact member 4 and reduce vibration of the sagger 240. The roller is connected to the first clamping block 51 via a second bolt 54, which locks the roller to the first clamping block 51, preventing relative rotation between the two. The roller is made of wear-resistant polyurethane or rubber to enhance its durability under high temperature and high load conditions. This material choice helps reduce roller wear and extend the service life of the sensing device 100. The diameter and width of the roller can be customized based on the size and weight of the sagger 240 to ensure optimal contact and propulsion. This customized roller design provides better adaptability and performance, especially when processing saggers 240 of different specifications.

[0048] Further, see Figure 1 and Figure 5 In one embodiment of the present invention, a first arcuate groove is provided on the side of the first clamping block 51 facing the second clamping block 52, and a second arcuate groove is provided on the side of the second clamping block 52 facing the first clamping block 51. The rotating shaft 3 is constrained between the first and second arcuate grooves. The provision of arcuate grooves that match the rotating shaft 3 increases the contact area between the first clamping block 51 or the second clamping block 52 and the rotating shaft 3, improving the friction between the first clamping block 51 or the second clamping block 52 and the rotating shaft 3. The grooves also serve to limit the rotating shaft 3 and ensure strong clamping.

[0049] Further, in order to improve the accuracy of the sensing device 100 and adapt to a more efficient high temperature carbonization automatic production line 200, please refer to Figure 8 In one embodiment of the present invention, the sensing device 100 includes a rotating shaft 3 and a plurality of contact members 4, which are spaced apart from the rotating shaft 3. Thus, within a batch, each sagger corresponds to a corresponding contact member 4. The size of the contact member 4 can be reduced to only be sufficient for sensing a single sagger, resulting in more uniform force distribution and improved accuracy of the sensing device 100.

[0050] The present invention also proposes a high temperature carbonization automatic production line 200, please refer to Figure 8In one embodiment of the present utility model, the high-temperature carbonization automatic production line 200 includes a pushing device 210, an electric gate 220, a conveying device, and a sensing device 100 as in any one of the above-mentioned embodiments. Since the high-temperature carbonization automatic production line 200 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the pushing device 210 accommodates a sagger 240, the conveying device has a conveying frame 230, the output end of the pushing device 210 is connected to the input end of the conveying device, the electric gate 220 is arranged on the conveying frame 230 at the input end of the conveying device, the sensing device 100 is arranged on the conveying frame 230 on the side of the electric gate 220 facing away from the pushing device 210, and the sensing device 100 is connected to the electric gate 220 in communication.
