Description

Technical Field

[0001] The utility model relates to the technical field of dust collection equipment, in particular to a box body dust removal mechanism. Background Art

[0002] With the rapid development of new energy technologies, lithium batteries, as important energy storage and supply devices, have been widely used in electronic products such as electric vehicles, smart phones, and wearable devices. In the production process of lithium batteries, the vacuum baking process is a key step to remove moisture inside the battery cells and improve the performance and safety of the batteries. However, in the actual production process, there are a series of technical challenges and potential risks, especially the cleaning and dust removal of the oven cavity during the baking process.

[0003] In the current lithium battery vacuum baking process, it is usually required that the injection hole be kept sealed during baking to prevent external contaminants from entering the battery cells. However, in some cases, due to improper operation or equipment design defects, the injection hole may not be completely sealed, resulting in the entry of external air and pollutants into the oven cavity, contaminating the battery cells. For example, if the oven cavity is not cleaned for a long time, a large amount of particles and other foreign objects will accumulate in the cavity. These foreign objects will not only affect the baking effect of the oven, but may also enter the battery cells through the unsealed injection hole, contaminating the battery cells and thus affecting the performance and safety of the batteries.

[0004] To solve the above problems, the prior art usually adopts the method of manual cleaning to remove the particles in the oven cavity. However, this method has the following defects: first, it cannot be cleaned regularly, resulting in potential pollution sources always existing in the oven cavity; second, it is difficult to completely remove all particles manually, and there is a risk of incomplete cleaning; third, the manual cleaning efficiency is low, increasing the production cost and time cost. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a box body dust removal mechanism, which can solve the problem of dust cleaning inside the oven cavity.

[0006] The technical solution adopted by the utility model to solve its problems is:

[0007] A box dust removal mechanism, comprising: a support frame, the support frame enclosing to form a receiving cavity; a suction fan, the suction fan being located in the receiving cavity and fixedly connected to the support frame; a dust collection box, the dust collection box being located in the receiving cavity and fixedly connected to the support frame; a movement track, the movement track including a top track provided on the top of the support frame and a bottom track provided on the bottom of the support frame; a dust suction mechanism, the dust suction mechanism including a suction pipe and an upper sliding mechanism and a lower sliding mechanism located at both ends of the suction pipe, the suction pipe being communicated with the suction fan and the dust collection box, the upper sliding mechanism sliding along the top track, and at the same time the lower sliding mechanism sliding along the bottom track to drive the suction pipe to perform a circumferential movement along the side wall of the receiving cavity.

[0008] By adopting the above solution, the suction fan of the dust suction mechanism can generate suction force, combined with the suction pipe and the dust collection box, it can effectively suck and collect foreign matters such as particles in the oven cavity, thereby preventing these foreign matters from entering the inside of the battery cell through the unsealed liquid injection hole and causing battery cell pollution; compared with manual cleaning, this box dust removal mechanism has a high degree of automation. The design of the upper sliding mechanism and the lower sliding mechanism enables the dust suction mechanism to perform a circumferential movement along the side wall of the oven cavity, which can ensure a comprehensive and thorough cleaning of the oven cavity and further reduce the risk of pollution.

[0009] Further, the support frame includes a top frame, a bottom frame and side support rods, the top frame and the bottom frame are connected by the side support rods, the dust suction mechanism and the dust collection box are arranged in the center of the bottom frame, the top track is arranged around the edge of the top frame, and the bottom track is arranged around the edge of the bottom frame.

[0010] By adopting the above solution, the support frame is assembled with flanges, which is beneficial to making the suction pipe perform a circumferential movement along the side wall of the receiving cavity and realizing a more comprehensive dust suction effect inside the box.

[0011] Further, the top track and the bottom track both include a plurality of straight tracks and a plurality of steering tracks, and the straight tracks and the steering tracks are alternately connected in sequence to form a closed track.

[0012] By adopting the above solution, a closed track in the shape of a rounded rectangle can be enclosed by the straight track and the steering track, which is more suitable for the box structure. At the same time, the closed track enables the dust suction mechanism not to start and stop frequently during the cleaning process, thereby improving the cleaning efficiency.

[0014] By adopting the above scheme, the fitting design of the pulley and the movement track can significantly reduce the frictional resistance during sliding, enabling the upper sliding mechanism and the lower sliding mechanism to slide along the track more smoothly and efficiently.

[0015] Further, the inner sides of the top track and the bottom track are provided with concave arc surfaces, and the arc surfaces are abutted against the pulleys.

[0016] By adopting the above scheme, the arc surface forms a contact point that can keep the pulley sliding stably, ensuring that the dust suction mechanism maintains a stable posture during the sliding process and preventing shaking or deviation from the track caused by uneven tracks or vibrations.

[0017] Further, a driving device is also provided on the support frame, and the driving device is used to drive the upper sliding mechanism to slide along the top track and drive the lower sliding mechanism to slide along the bottom track.

[0018] By adopting the above scheme, the driving device can automatically control the movement of the upper sliding mechanism and the lower sliding mechanism without manual operation, improving the automation degree of the entire dust removal mechanism. This automated operation not only reduces the need for manual intervention but also reduces the risk of operation errors.

[0019] Further, a plurality of bottom pulleys are provided, the plurality of bottom pulleys are all connected to the support frame, and the plurality of bottom pulleys are arranged at intervals along the inner side of the bottom track; a bottom conveyor belt is wound around the bottom pulleys, and the lower sliding mechanism rotates following the rotation of the bottom conveyor belt; a driving motor, the output end of the driving motor is drivingly connected to any one of the bottom pulleys.

[0020] By adopting the above scheme, the bottom pulleys are arranged at intervals along the inner side of the bottom track, ensuring that the conveyor belt can transmit power stably and evenly, allowing the lower sliding mechanism to rotate following the bottom conveyor belt, thereby realizing a fast and stable sliding movement.

[0021] Further, convex blocks are provided on the bottom conveyor belt, and the convex blocks are connected to the upper sliding mechanism or the lower sliding structure.

[0022] By adopting the above solution, the design of the bumps allows for precise control of the positions of the upper sliding mechanism and the lower sliding mechanism on the conveyor belt. By adjusting the positions and quantities of the bumps, the accurate positions of the upper sliding mechanism and the lower sliding mechanism on the conveyor belt can be ensured, thereby achieving more precise motion control and cleaning effect.

[0023] Further, the quantity ratio of the connecting columns, sliding frames and pulleys in the upper sliding mechanism and the lower sliding mechanism is 1:1:2.

[0024] By adopting the above solution, a stable abutting surface can be formed by two pulleys. When sliding along the motion track, the angle of the pulley frame can be changed following the turning of the motion track, thereby driving the suction pipe to rotate, and further changing the suction angle of the suction pipe to achieve the effect of comprehensive dust suction.

[0025] Further, the suction air pipe includes a longitudinal suction air pipe and a horizontal suction air pipe. The longitudinal suction air pipe is provided with a first suction air port facing the side surface of the accommodation cavity, and the horizontal suction air pipe is provided with a second suction air port facing the top surface or the bottom surface of the accommodation cavity.

[0026] By adopting the above solution, through the all-round air suction design, the dead corners and blind areas in the accommodation cavity can be reduced, the air suction area can be comprehensively covered, and the air suction efficiency can be improved.

[0027] In summary, a box body dust removal mechanism provided by the present utility model has the following technical effects:

[0028] 1. By generating suction force through the suction fan of the dust suction mechanism and combining with the suction air pipe and the dust collection box, foreign matters such as particles and dust in the oven cavity can be effectively sucked in and collected.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0042] Refer to Embodiment 1 of this utility model Figures 1-6 As shown, a box body dust removal mechanism is disclosed, which is applied to a battery baking oven and can of course also be applied to other places that require dust removal. This embodiment does not make specific limitations. The box body dust removal mechanism includes a support frame 1, a suction fan 2, a dust collection box 3, a movement track 4 and a dust suction mechanism 5. The support frame 1 encloses to form a receiving cavity 11, and the receiving cavity 11 communicates with the inner side wall of the battery baking oven to facilitate dust suction from the inner side wall of the battery baking oven. The movement track 4 includes a top track 41 provided at the top of the support frame 1 and a bottom track 42 provided at the bottom of the support frame 1. The dust suction mechanism 5 includes a suction pipe 51 and upper and lower sliding mechanisms 52 and 53 located at both ends of the suction pipe 51. The upper sliding mechanism 52 slides along the top track 41, and at the same time, the lower sliding mechanism 53 slides along the bottom track 42 to drive the suction pipe 51 to perform a circular motion along the side wall of the receiving cavity 11. The suction fan 2 is located in the receiving cavity 11 and is fixedly connected to the support frame 1. The suction fan 2 is connected to the dust collection box 3 through an air pipe 8.

[0043] During use, after opening the sealed door of the battery baking oven and taking out the battery tray by the fixture loading and unloading robot, the support frame 1 is clamped to move the entire box body dust removal mechanism and place it into the battery baking oven. When the suction fan 2 is started, the inner side wall of the battery baking oven can be dusted by the sliding of the dust suction mechanism 5 in the bottom track 42 and the top track 41. After the dust suction mechanism 5 makes a full circle, the automatic cleaning work inside the battery baking oven is completed. Through the suction force generated by the suction fan 2 of the dust suction mechanism 5, combined with the suction pipe 51 and the dust collection box 3, particles and other foreign objects in the oven cavity can be effectively sucked in and collected.

[0044] Preferably, refer to Figures 4-5 As shown, a clamping frame 6 can be assembled on the outside of the support frame 1. The clamping frame 6 can enable the box body dust removal mechanism to be assembled with the chute for assembling the battery tray when placed in the battery baking oven, which is beneficial to adapting to and being fixedly assembled with the battery baking oven. Optimally, the inner sides of the top track 41 and the bottom track 42 are provided with concave arc surfaces, and the arc surfaces abut against the pulley 523. The arc surfaces form a contact point that can make the pulley 523 slide stably, ensuring that the dust suction mechanism 5 maintains a stable posture during the sliding process and preventing shaking or deviation from the track caused by uneven tracks or vibrations.

[0045] In the present Embodiment 1, referring to Figure 1 as shown, the support frame 1 includes a top frame 12, a bottom frame 13 and side support rods 14. The top frame 12 and the bottom frame 13 are connected by the side support rods 14. The dust suction mechanism 5 and the dust collection box 3 are arranged at the center of the bottom frame 13 and can be fixed by bolts. The top track 41 is arranged around the edge of the top frame 12, and the bottom track 42 is arranged around the edge of the bottom frame 13. Both the top track 41 and the bottom track 42 include a plurality of straight tracks 411 and a plurality of turning tracks 412. The straight tracks 411 and the turning tracks 412 are alternately connected in sequence to form a closed track with a rounded rectangular structure. Both the upper sliding mechanism 52 and the lower sliding mechanism 53 include a connecting column 521, a sliding frame 522 and a pulley 523. One end of the connecting column 521 is connected to the suction pipe 51. One side of the sliding frame 522 is connected to the other end of the connecting column 521. The pulley 523 is rotatably connected to the other side of the sliding frame 522, and the rolling surface of the pulley 523 is in contact with the movement track 4. The quantity ratio of the connecting column 521, the sliding frame 522 and the pulley 523 in the upper sliding mechanism 52 and the lower sliding mechanism 53 is 1:1:2.

[0046] Preferably, referring to Figure 1 , Figure 5 and Figure 6 as shown, there are two connecting columns 521 in the lower sliding mechanism 53, and there are two sliding frames 522 which are respectively arranged on the connecting columns 521. The number of pulleys 523 is four, and two pulleys 523 are arranged on each connecting column 521. There is one connecting column 521 in the upper sliding mechanism 52, one sliding frame 522, and the number of pulleys 523 is two. Such an arrangement enables the upper sliding mechanism 52 to only provide a guiding function. The lower sliding mechanism 53 can form a stable abutting surface through the pulleys 523 on the two sliding frames 522. When sliding along the movement track 4, the angle of the pulley 523 frame can be changed following the turning of the bottom track 42 in the movement track 4, thereby driving the suction pipe to rotate, and further changing the dust suction angle of the suction pipe to achieve the effect of comprehensive dust suction.

[0047] In order to enable the top surface of the accommodation cavity 11 to also achieve the dust suction effect, referring to Figure 2As shown, in some embodiments, the suction duct 51 includes a longitudinal suction duct 511 and a horizontal suction duct 512, the longitudinal suction duct 511 is provided with a first suction port 513 facing the side of the accommodating cavity 11, and the horizontal suction duct 512 is provided with a second suction port 514 facing the top surface or the bottom surface of the accommodating cavity 11. In this embodiment, the second suction port 514 faces the top surface, and the horizontal suction duct 512 is vertically connected to the top end of the longitudinal suction duct 511. When the upper sliding mechanism 52 and the lower sliding mechanism 53 at both ends of the longitudinal suction duct 511 rotate along the motion track 4 respectively, the first suction port 513 can always face the inner side wall of the battery baking box outside the accommodating cavity 11, and the second suction port 514 can always face the top wall of the battery baking box at the top of the accommodating cavity 11. Through the all-round suction design, the dead angles and blind spots in the accommodating cavity 11 can be reduced, the suction area can be fully covered, and the suction efficiency can be improved.

[0048] For intelligent control, refer to Figure 1 As shown, in this embodiment 1, the support frame 1 is further provided with a driving device 7, which is used to drive the upper sliding mechanism 52 to slide along the top track 41, and drive the lower sliding mechanism 53 to slide along the bottom track 42, and can automatically control the movement of the upper sliding mechanism 52 and the lower sliding mechanism 53 without manual operation, thereby improving the automation of the entire dust removal mechanism. This automated operation not only reduces the need for manual intervention, but also reduces the risk of operational errors.

[0049] In a specific embodiment, see Figure 1 , Figure 3 and Figure 6 As shown, the driving device 7 includes a bottom pulley 71, a bottom conveyor belt 72 and a driving motor 73. The bottom pulley 71 is provided with a plurality of them, and the plurality of bottom pulleys 71 are connected to the bottom frame 13 of the support frame 1, and the plurality of bottom pulleys 71 are arranged at intervals along the inner side of the bottom track 42. The bottom conveyor belt 72 is wound around the bottom pulley 71, and the lower sliding mechanism 53 rotates following the rotation of the bottom conveyor belt 72. The output end of the driving motor 73 is connected to any of the bottom pulleys 71 for driving, and the bottom pulleys 71 are arranged at intervals along the inner side of the bottom track 42, ensuring that the conveyor belt can stably and evenly transmit power, allowing the lower sliding mechanism 53 to rotate following the bottom conveyor belt 72, thereby achieving fast and smooth sliding motion. In order to prevent the upper sliding mechanism 52 from detaching from the top track 41, optionally, a top pulley and a top conveyor belt can be arranged on the top frame 12, and the upper sliding mechanism 52 can be limited in cooperation with the top track 41, thereby improving the sliding stability of the upper sliding mechanism 52.

[0050] To facilitate the upper sliding mechanism 52 and the lower sliding mechanism 53 to rotate along with their respective conveyor belts, refer to Figure 6 As shown, bumps 74 are provided on the bottom conveyor belt 72, and the bumps 74 are connected to the upper sliding mechanism 52 or the lower sliding structure. Preferably, two bumps 74 are provided on the conveyor belt, which are respectively abutted against both sides of the upper sliding mechanism 52 or both sides of the lower sliding structure. The design of the bumps 74 allows for precise control of the positions of the upper sliding mechanism 52 and the lower sliding mechanism 53 on the conveyor belt. By adjusting the positions and quantities of the bumps 74, the accurate positions of the upper sliding mechanism 52 and the lower sliding mechanism 53 on the conveyor belt can be ensured, thereby achieving more precise motion control and cleaning effect.

[0051] It should be noted that, refer to Figure 5 As shown, multiple groups of box dust removal mechanisms can be provided in a battery baking oven. When two groups of box dust removal mechanisms are provided, the two box dust removal mechanisms are symmetrically arranged, that is, the top track 41 of the box dust removal mechanism on the upper side faces the top of the battery baking oven, and the top track 41 of the box dust removal mechanism on the lower side faces the bottom of the battery baking oven, so as to achieve comprehensive dust suction on the top surface, bottom surface and four side surfaces inside the battery baking oven.

[0052] During use, after opening the sealed door of the battery baking oven and taking out the battery tray by the fixture loading and unloading robot, the clamping support frame 1 moves the whole box dust removal mechanism and places it into the battery baking oven, and the clamping frame 6 outside the support frame 1 is fixed to the chute where the battery tray is assembled; when the driving motor 73 is started, the bump 74 can drive the upper sliding mechanism 52 and the lower sliding mechanism 53 to move along with the conveyor belt, so that the upper sliding mechanism 52 and the lower sliding mechanism 53 slide along their respective movement tracks 4. During the sliding process, the first air suction port 513 and the second air suction port 514 always face the inner wall of the battery baking oven; the air suction fan 2 is turned on, and the air suction fan 2 is connected to the air suction pipe 51 through the air pipe 8, so that the first air suction port 513 of the longitudinal air suction pipe 511 and the second air suction port 514 of the horizontal air suction pipe 512 have suction force, realizing comprehensive dust suction on the inner side wall and the top wall of the battery baking oven. Through the dust suction mechanism 5 moving around for one week, the particles and other foreign matters in the oven cavity are effectively sucked in and collected into the dust collection box 3.

[0053] In summary, a box dust removal mechanism provided by the present utility model has the following technical effects:

[0054] 1. By generating suction force through the air suction fan 2 of the dust suction mechanism 5, combined with the air suction pipe 51 and the dust collection box 3, the particles, dust and other foreign matters in the oven cavity can be effectively sucked in and collected. Especially the design of the upper sliding mechanism 52 and the lower sliding mechanism 53 enables the dust suction mechanism 5 to move around along the side wall of the oven cavity, realizing comprehensive cleaning of the oven cavity and ensuring no dead corners and omissions;

[0055] 2. Compared with the traditional manual cleaning method, this box dust removal mechanism has a high degree of automation. It does not require direct manual participation in the cleaning process, greatly improving the cleaning efficiency and reducing the production cost and time cost;
