[0033] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings, in which the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0034] Reference is made below Figures 1-3 The sagger stroke detection device 100 according to the embodiments of the present application is described below, which can be used for position detection of the sagger to determine whether the sagger on the roller bed is in place.

[0035] It can be understood that the sagger stroke detection device 100 in the present application can be applied to the product production detection technical field, such as: applied to the production detection of new energy lithium battery materials, and specifically applied to the sagger in-place detection inside the roller kiln.

[0036] At present, in the production process of lithium batteries, the roller kiln is used to perform high-temperature sintering reaction on the battery raw materials loaded in the sagger inside the roller kiln. Among them, the running state of the sagger inside the roller kiln plays a decisive role in the final performance of the product and the running stability of the equipment in the roller kiln. Through the sagger stroke detection device 100 at the inlet and outlet of the kiln, the running state of the sagger can be tracked and signal feedback can be realized, so that the sagger running disorder, tilt, sintering cycle abnormality, etc. can be found in time, which helps to improve the product pass rate and reduce the risk of major failures of the roller kiln.

[0037] It can be understood that the main material of the sagger is mullite and the battery raw material is a powdery particle, and in the process of equipment operation in the roller kiln, granular debris, dust and other foreign matters will be generated. When the foreign matters enter the inside of the sagger stroke detection device 100, it will cause the sagger stroke detection device 100 to appear operation jam or lock, thereby causing abnormal alarm and stopping driving of the equipment, affecting the normal operation of the sagger stroke detection device 100. In the related art, if the sagger stroke detection device 100 appears jam or lock failure, the on-site operator mainly finds the equipment abnormity through inspection, and further through the repair process, the sagger stroke detection device 100 is disassembled, cleaned, lubricated, and reassembled by the equipment maintenance personnel, and the safety risk in the maintenance process is high, and the production cycle is affected.

[0038] Referring to Figure 1 As shown in the figure, the sagger stroke detection device 100 according to the embodiment of the present application comprises a seat body 1, a gravity rod 2, a guide cylinder 3 and a transmission mechanism 4.

[0039] Among them, the seat body 1 is provided with a mounting hole penetratingly arranged along the vertical direction, the gravity rod 2 is arranged through the mounting hole along the vertical direction, and the guide cylinder 3 is arranged through the mounting hole along the vertical direction and fixedly connected with the seat body 1, the outer peripheral wall of the guide cylinder 3 is arranged in a spaced manner with the inner peripheral wall of the mounting hole, so as to form a gap between the outer peripheral wall of the guide cylinder 3 and the inner peripheral wall of the mounting hole, the gap is the foreign matter discharge port 101, and the foreign matter falling from above the seat body 1 can be discharged at the foreign matter discharge port 101, avoiding the foreign matter accumulated on the seat body 1 from falling into the guide cylinder 3. Further, the guide cylinder 3 is used for guiding cooperation with the gravity rod 2, so as to guide the movement of the gravity rod 2 through the guide cylinder 3, improving the stability of the gravity rod 2 in the process of position change.

[0040] It can be understood that the sagger passes through above the sagger stroke detection device 100, and the sagger exists the situation of falling foreign matters (such as granular sand, dust and the like) in the conveying process, if the foreign matters fall in the guide cylinder 3, the foreign matters are easy to be stuck between the outer wall surface of the gravity rod 2 and the inner peripheral wall of the guide cylinder 3, thereby causing the lifting action of the gravity rod 2 to appear jam or lock, affecting the action of the sagger stroke detection device 100. In the present application, the gap for falling foreign matters is formed between the outer peripheral wall of the guide cylinder 3 and the inner peripheral wall of the mounting hole, so that the foreign matters can fall below the seat body 1 through the foreign matter discharge port 101 between the guide cylinder 3 and the mounting hole, thereby effectively preventing the situation of jam or lock of the gravity rod 2, improving the operation reliability and stability of the sagger stroke detection device 100.

[0041] Further, the transmission mechanism 4 is installed on the seat body 1, and the transmission mechanism 4 has a driving end 411 for cooperating with the saggar and a driven end connected with the top end of the gravity rod 2. When the saggar passes above the saggar stroke detection device 100, the saggar cooperates with the driving end 411 and pulls up the gravity rod 2 through the driven end, so as to trigger the detection switch to realize the saggar in-place detection of the saggar stroke detection device 100.

[0042] It can be understood that, when the saggar stroke detection device 100 in the application is applied to a roller kiln, the saggar stroke detection device 100 can be arranged at the gap between two adjacent conveying rollers in the roller, the conveying rollers of the roller are used for conveying the saggar, and when the saggar is conveyed above the saggar stroke detection device 100, the saggar can be in transmission cooperation with the driving end 411 of the transmission mechanism 4 to pull up the gravity rod 2 through the driven end, so as to adjust the position of the gravity rod 2.

[0043] It should be noted that, during the position transformation of the gravity rod 2, a preset condition can be triggered to determine the in-place condition of the saggar. The above-mentioned "preset condition" refers to that the gravity rod 2 is displaced by a preset distance (such as 10 cm, 15 cm), and a proximity switch can be arranged on the gravity rod 2, so that whether the saggar is in place can be judged based on the state of the proximity switch. The manner of triggering the preset condition is not limited thereto, and a signal change based on the position transformation of the gravity rod 2 can be used to judge whether the saggar is in place.

[0044] According to the saggar stroke detection device 100 in the embodiments of the application, the seat body 1 is a mounting carrier of the transmission mechanism 4 and the guide cylinder 3, and the gravity rod 2 is connected with the transmission mechanism 4 to drive the gravity rod 2 to move through the transmission mechanism 4, so that the gravity rod 2 can be pulled up by the transmission mechanism 4 when the saggar is in place, that is, the in-place detection of the saggar by the saggar stroke detection device 100 is triggered. The guide cylinder 3 can guide the movement of the gravity rod 2 in the vertical direction to improve the stability of the movement of the gravity rod 2, and the foreign matter discharge port 101 is formed between the outer circumferential wall of the guide cylinder 3 and the inner circumferential wall of the mounting hole, so as to avoid the foreign matter falling above the saggar stroke detection device 100 from entering the guide cylinder 3 to cause the gravity rod 2 to be stuck, and improve the operation reliability and stability of the saggar stroke detection device 100.

[0045] In some embodiments of the application, the rib plate 11 is connected between the outer circumferential wall of the guide cylinder 3 and the inner circumferential wall of the mounting hole, so as to connect and fix the guide cylinder 3 and the seat body 1 through the rib plate 11, and the connection manner is simple and has high reliability.

[0046] The rib 11 is a plate-shaped structure and is arranged vertically to reduce the area of ​​the gap between the guide cylinder 3 and the mounting hole (i.e., the foreign matter discharge port 101) that the rib 11 blocks, thus ensuring the foreign matter discharge effect of the foreign matter discharge port 101.

[0047] like Figure 1 As shown, in a further embodiment of this application, the ribs 11 are configured as a plurality of ribs, and the plurality of ribs 11 are arranged at intervals along the circumferential direction of the guide cylinder 3, so as to improve the connection reliability between the guide cylinder 3 and the seat 1 through the plurality of ribs 11.

[0048] It is understandable that when multiple ribs 11 are arranged between the guide cylinder 3 and the base 1, the multiple ribs 11 can divide the foreign object discharge port 101 to form multiple through holes, and the multiple through holes are arranged sequentially around the guide cylinder 3 in the circumferential direction, so that foreign objects at any position in the circumferential direction of the guide cylinder 3 can fall through their corresponding through holes.

[0049] In some alternative embodiments, the rib plate 11, the guide cylinder 3, and the seat 1 can all be constructed as metal parts (such as cast iron parts, cast aluminum parts, etc.), and the rib plate 11 can be connected and fixed to the guide cylinder 3 and the seat 1 respectively by welding.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the top of the guide cylinder 3 protrudes upward from the upper surface of the seat 1, thereby increasing the difficulty for foreign objects to fall from the open end above the guide cylinder 3 into the guide cylinder 3 and reducing the risk of foreign objects entering the guide cylinder 3.

[0051] Understandably, when a foreign object falls from above the crucible travel detection device 100, it may land on the upper surface of the base 1, accumulating there or splashing upon contact with the surface. In this application, by increasing the height of the guide cylinder 3 protruding above the upper surface of the base 1, foreign objects scattered on the base 1 and around the guide cylinder 3 cannot directly enter the guide cylinder 3. Furthermore, this increases the difficulty for splashed foreign objects to enter the guide cylinder 3 through its upper end, thus improving the protective effect at the guide cylinder 3 and ensuring the operational reliability and stability of the gravity rod 2.

[0052] When a foreign object falls onto the seat 1 and is located around the guide cylinder 3, the foreign object will preferentially fall through the foreign object discharge port 101 located on the outer side of the guide cylinder 3.

[0053] Reference Figure 2As shown, in some embodiments of this application, the upper surface of the seat 1 is planar and horizontally arranged. The top end of the guide cylinder 3 protrudes vertically upward from the upper surface of the seat 1 by a height L1, satisfying the relationship L1≥5mm. When L1 satisfies the above relationship, it effectively prevents foreign objects from falling into the guide cylinder 3.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the top of the gravity rod 2 is provided with a connecting seat 21, which is connected to the transmission mechanism 4. The transmission mechanism 4 is arranged in the upper region of the guide cylinder 3. The bottom surface of the connecting seat 21 can be positioned and engaged with the top of the guide cylinder 3 to limit the downward movement of the gravity rod 2 through the top of the guide cylinder 3.

[0055] The connecting seat 21 is an installation structure on the gravity rod 2 for connecting and cooperating with the transmission mechanism 4. The connecting seat 21 is located on the outside of the guide cylinder 3, and the bottom surface of the connecting seat 21 is arranged opposite to the guide cylinder 3 in the vertical direction.

[0056] Understandably, the transmission mechanism 4 can drive the connecting seat 21 to move, thereby lifting the gravity rod 2. When the transmission mechanism 4 no longer applies driving force to the gravity rod 2, the gravity rod 2 falls under the action of gravity, and the bottom surface of the connecting seat 21 can abut against the top of the guide cylinder 3, so that the gravity rod 2 and the guide cylinder 3 are positioned and engaged, meaning that the gravity rod 2 cannot move further downward relative to the guide cylinder 3. In other words, the gravity rod 2 can achieve vertical upward movement through the lifting of the transmission mechanism 4, and the gravity rod 2 can achieve downward return to its original position under the action of gravity. Furthermore, during the position change of the gravity rod 2, it maintains guiding engagement with the guide cylinder 3 to improve the stability of the position change process of the gravity rod 2.

[0057] In some embodiments of this application, the connecting seat 21 is configured as a frustum, and the top surface area of ​​the frustum is smaller than the bottom surface area, so that the peripheral wall of the frustum is gradually inclined outward from the top surface to the bottom surface. Foreign objects falling on the peripheral side wall of the connecting seat 21 can diffuse outward from the periphery of the frustum, preventing foreign objects from falling into the guide cylinder 3. In other embodiments of this application, the connecting seat 21 is configured as a truncated pyramid, and the top surface area of ​​the truncated pyramid is smaller than the bottom surface area, so that at least one side wall of the truncated pyramid is gradually inclined outward from the top surface to the bottom surface. Foreign objects falling on the side wall of the truncated pyramid can diffuse outward from the periphery of the truncated pyramid, preventing foreign objects from falling into the guide cylinder 3.

[0058] Understandably, the connecting seat 21 is constructed as a frustum or prism with a top surface area smaller than its bottom surface area, causing it to gradually expand downwards. This allows the connecting seat 21 to form an umbrella-like structure above the open top end of the guide cylinder 3, which disperses foreign objects falling onto the connecting seat 21 outwards, preventing them from falling into the guide cylinder 3 directly below the connecting seat 21. Alternatively, the connecting seat 21 can be constructed as a conical structure (e.g., a cone, pyramid, etc.), forming a gradually expanding downwards guide structure that disperses foreign objects outwards.

[0059] In some embodiments of this application, in the vertical projection, the projection of the guide cylinder 3 falls within the projection range of the bottom surface of the connecting seat 21. The connecting seat 21 can fully cover the open top end of the guide cylinder 3, thereby preventing foreign objects from falling into the guide cylinder 3. Furthermore, the guide cylinder 3 can guide foreign objects falling from top to bottom onto the connecting seat 21 outwards, thereby reducing the risk of foreign objects falling into the guide cylinder 3.

[0060] In some embodiments of this application, in the vertical projection, the bottom projection of the connecting seat 21 falls within the projection range of the mounting hole. Foreign objects falling onto the connecting seat 21 can fall into the foreign object discharge port 101, reducing the accumulation of foreign objects on the seat body 1. It is understood that when a foreign object above the crucible stroke detection device 100 falls from top to bottom, the connecting seat 21 can avoid the foreign object discharge port 101, allowing the foreign object to fall through the foreign object discharge port 101 to the bottom of the seat body 1.

[0061] In a further embodiment of this application, in the vertical projection of the sagger travel detection device 100, if the projection of the guide cylinder 3 falls within the projection range of the bottom surface of the connecting seat 21 and the projection of the guide cylinder 3 falls within the projection range of the bottom surface of the connecting seat 21, the foreign object discharge port 101 is exposed while the top open end of the guide cylinder 3 is blocked by the connecting seat 21, so that the falling foreign object can fall through the foreign object discharge port 101, thus preventing the foreign object from falling into the guide cylinder 3.

[0062] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the base 1 is provided with a mounting bracket 12, which is used to install the transmission mechanism 4. That is, the mounting bracket 12 is a mounting carrier provided on the base 1 for installing the transmission mechanism 4.

[0063] Furthermore, the transmission mechanism 4 includes a first link 41 and a second link 42. One end of the first link 41 is configured as a driving end 411, and the first link 41 is rotatably mounted on the mounting bracket 12 about a first axis 61. One end of the second link 42 is rotatably connected to the first link 41 about a second axis 62, and the other end of the second link 42 is configured as a driven end and is rotatably connected to the gravity rod 2 about a third axis 63. The first axis 61, the second axis 62, and the third axis 63 are arranged parallel to each other.

[0064] Understandably, the transmission mechanism 4 is composed of multiple connecting rods, which improves the stability and reliability of the transmission of driving force. Furthermore, the connecting rods are easy to install and assemble. Simultaneously, the direction of the driving force can be changed through the rotation and oscillation of the multiple connecting rods, facilitating the lifting of the gravity rod 2 via the transmission mechanism 4.

[0065] The crucible stroke detection device 100 is arranged in the roller conveyor, and the crucible passes laterally through the crucible stroke detection device 100 under the action of the conveyor roller. When the crucible cooperates with the transmission mechanism 4, the crucible can apply a lateral driving force to the drive end 411, and through the cooperation between multiple connecting rods (such as the first connecting rod 41 and the second connecting rod 42), the gravity rod 2 can be lifted to realize the position adjustment of the gravity rod 2, so as to realize the positioning detection of the crucible.

[0066] Reference Figure 2 As shown, the sagger (not shown) can pass from left to right above the sagger stroke detection device 100, so that the sagger can abut the drive end 411 and drive the drive part to move to the right, so that the first connecting rod 41 rotates clockwise around the first axis 61, and the first connecting rod 41 can further drive the second connecting rod 42 to swing. The connection end of the second connecting rod 42 and the first connecting rod 41 moves upward, and the second connecting rod 42 can drive the gravity rod 2 to move upward, thereby lifting the gravity rod 2 upward through the transmission mechanism 4.

[0067] Understandably, driven by the first link 41, the motion trajectory of the second link 42 connected to the first link 41 is arc-shaped. The gravity rod 2 rises vertically under the action of the guide cylinder 3. During the rise of the gravity rod 2, the two ends of the second link 42 rotate around the second axis 62 and the third axis 63 respectively. That is, the upper end of the second link 42 (i.e. the connection end between the second link 42 and the first link 41) gradually moves to the left, and the second link 42 swings counterclockwise around the third axis 63.

[0068] It should be noted that the above-mentioned directions or positional relationships regarding "left," "right," "clockwise," and "counterclockwise" are based on the appendix. Figure 2The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0069] Among them, the first axis 61, the second axis 62 and the third axis 63 can be set parallel to the axial direction of the conveying roller in the roller conveyor, so that the swing direction of the connecting rod is suitable to match the conveying direction of the sagger, and can convert the lateral driving force applied by the sagger to the transmission mechanism 4 into the displacement of the gravity rod 2 in the vertical direction, and then judge the positioning status of the sagger based on the position change of the gravity rod 2 in the vertical direction.

[0070] In some embodiments of this application, the first link 41 is arranged in a V-shape, so that the driving end 411 of the first link 41 and the connection end of the first link 41 and the second link 42 can be staggered, which makes it easier to arrange the second link 42 and the gravity rod 2 in an area that is suitable for avoiding the mounting bracket 12, thereby preventing interference between the second link 42 and the mounting bracket 12.

[0071] In some embodiments of this application, the drive end 411 of the first link 41 is constructed as a roller, which can roll in conjunction with the sagger, thereby reducing the resistance applied by the drive end 411 to the sagger and ensuring the passage of the sagger at the sagger stroke detection device 100.

[0072] In some embodiments of this application, the mounting bracket 12 can be fixed to the base 1 by screwing, thereby reducing the difficulty of assembling and disassembling the mounting bracket 12 and the base 1. The structure of the mounting bracket 12 can be designed according to the structure of the transmission mechanism 4, the gravity rod 2, and the arrangement of the sagger stroke detection device 100 in the roller conveyor, so that the shape of the mounting bracket 12 can avoid obstacles to equipment such as the conveyor rollers while meeting the movement requirements of the transmission mechanism 4 and the gravity rod 2. The specific structure of the mounting bracket 12 is not limited here.

[0073] like Figure 4 As shown, in some embodiments of this application, the sagger travel detection device 100 further includes a collection box 5, which has an upwardly open collection groove (not shown). The collection box 5 is disposed below the base 1 and is connected to the guide cylinder 3. The open side of the collection groove is arranged opposite to the mounting hole in the vertical direction, so that foreign objects falling from the foreign object discharge port 101 to the base 1 can be collected in the collection groove, so that the operator can collect and process the foreign objects in a unified manner.

[0074] The guide tube 3 serves as the mounting carrier for the collection box 5, allowing the collection box 5 to be installed and arranged below the base 1.

[0075] In other embodiments, the collection box 5 may also be installed and connected to the bottom of the base 1 to fix the collection box 5 on the base 1.

[0076] In some embodiments of this application, the collection box 5 is sleeved on the guide cylinder 3, and the open end of the collection box 5 abuts against the lower surface of the base 1, thereby sealing the foreign object discharge port 101 through the collection box 5, achieving the sealing of the base 1 at the mounting hole, so that foreign objects falling through the foreign object discharge port 101 can be collected in the collection box 5, preventing foreign objects from falling from the gap between the collection box 5 and the base 1, and improving the collection effect of the collection box 5 on foreign objects.

[0077] The collection box 5 can be connected to the outer peripheral wall of the guide cylinder 3 by snap-fit, or it can be connected and fixed to the guide cylinder 3 by a connector. The specific installation method of the collection box 5 is not specified here.

[0078] In a further embodiment of this application, the collection box 5 includes multiple sub-boxes, which are arranged sequentially around the guide cylinder 3 in the circumferential direction, so as to form the collection box 5 together with the multiple sub-boxes, and form an annular storage space below the base 1.

[0079] Understandably, when the collection box 5 is constructed by splicing together multiple sub-boxes, the installation difficulty of the collection box 5 at the guide cylinder 3 can be reduced. For example, two fan-shaped sub-boxes with a central angle of 180° can be fastened together from both sides of the guide cylinder 3 to form a ring-shaped collection structure.

[0080] In some embodiments of this application, the main body of the gravity rod 2 (e.g., the part of the gravity rod 2 outside the connecting seat 21) is constructed in a cylindrical shape. Correspondingly, the guide hole formed by the guide cylinder 3 has a circular cross-sectional shape in the vertical direction, so that the guide cylinder 3 is adapted to the shape of the main body of the gravity rod 2.

[0081] It should be noted that the main body of the gravity rod 2 can also be constructed as a prism, and the cross-sectional shape of the guide hole in the guide cylinder 3 is constructed to match the shape (e.g., polygonal) and size of the prism.

[0082] In some embodiments of this application, the sagger stroke detection device 100 further includes a vertical plate 13, which is connected to the base 1, and the vertical plate 13 can be connected and cooperated with the installation position of the sagger stroke detection device 100 to install the sagger stroke detection device 100 at a preset position.

[0083] The upright plate 13 can be connected and fitted with the mounting structure (such as a slot) formed at the mounting position through a plug-in installation method to realize the installation of the sagger stroke detection device 100. In other words, the sagger stroke detection device 100 can be installed and arranged at the preset position by vertical plugging and unplugging. The installation method is simple and can reduce the installation and maintenance difficulty of the sagger stroke detection device 100.

[0084] The sagger stroke detection device 100 according to the embodiments of this application has at least the following advantages over the prior art:

[0085] (1) A foreign matter discharge port 101 is formed on the base 1 and surrounds the guide cylinder 3, so that the particulate debris, dust and other foreign matter generated during the crucible stroke can fall to the bottom of the base 1 through the foreign matter discharge port 101, avoiding foreign matter entering the guide cylinder 3 and causing problems such as jamming or stuck at the gravity rod 2. This can effectively improve the operational reliability and stability of the crucible stroke detection device 100 and ensure the effectiveness of the crucible stroke detection device 100 in detecting the crucible's position.

[0086] (2) The top of the guide cylinder 3 protrudes upward from the seat body 1, so that foreign objects falling on the seat body 1 cannot directly enter the guide cylinder 3, further improving the protection effect of the guide cylinder 3.

[0087] (3) A connecting seat 21 is formed at the top of the gravity rod 2. The connecting seat 21 is designed to gradually expand from top to bottom, so that foreign objects falling at the connecting seat 21 can be diffused outward and prevent foreign objects from entering the guide cylinder 3.

[0088] (4) A collection box 5 is provided below the seat 1 to collect foreign objects falling from the foreign object discharge port 101 through the collection box 5, so as to facilitate the unified collection and treatment of foreign objects falling below the seat 1.
