Description

Technical Field

[0001] This invention belongs to the field of nondestructive testing equipment technology, and particularly relates to a crucible testing device. Background Technology

[0002] Saggers used in the sintering of battery material powders are emptied after firing in a high-temperature kiln, and then refilled and fired again. Because the firing process requires high temperatures, the fired battery material needs to be cooled rapidly to meet performance requirements, but this is detrimental to the saggers. Due to frequent and rapid heating and cooling, stress concentration zones easily form on the sidewalls of the saggers, leading to cracks. Saggers with cracks cannot be returned to the kiln for further firing to prevent them from exploding during the process.

[0003] Existing testing methods mostly rely on manual visual inspection, which is not only inefficient but also prone to missed detections. This can lead to cracked saggers entering the kiln, and if the saggers explode, it results in waste of battery materials and makes cleaning inside the kiln inconvenient.

[0004] In response, some automated inspection equipment has emerged, using image inspection devices to inspect the side walls of the sagger, thereby improving inspection efficiency. However, during the tipping of the sagger, battery material may adhere to its outer wall. The wiping equipment only targets the inner wall of the sagger during the wiping process, resulting in the battery material adhering to the outer wall of the sagger not being removed in time. Long-term adhered battery material not being removed in time not only affects the inspection of the sagger, leading to missed detections and affecting the accuracy of the inspection, but also affects the heat transfer performance of the sagger. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention provides a sagger detection device that can avoid missed detections during sagger detection and improve the accuracy of sagger detection.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0043] like Figures 1-17 As shown, this embodiment provides a sagger detection device, including a conveying component 10, a positioning component 20, an erasing component 30, and an image acquisition component 40.

[0044] Specifically, such as Figures 1-3 As shown, the conveying assembly 10 includes a first conveying roller 11 arranged between two parallel and spaced side plates along the length direction of the two side plates, for conveying the saggers to be inspected and outputting the saggers that pass inspection, and a second conveying roller 12 provided on one side perpendicular to the conveying direction of the first conveying roller 11, for outputting the saggers with cracks.

[0045] A push plate 13 is provided on the other side of the conveying direction of the first conveying roller 11, and the push plate 13 is located above the side plate connected to the first conveying roller 11. A clearance hole 14 is provided on the distribution trajectory of the first conveying roller 11. Figure 1 and Figure 10 As shown, the two sides of the clearance hole 14 correspond to the push plate 13 and the second conveying roller 12 respectively. The push plate 13 is provided with a first linear mechanism 16 on the side away from the first conveying roller 11. The first linear mechanism 16 is mounted on a mounting base located on the side plate away from the second conveying roller 12.

[0046] The side of the clearance hole 14 facing the material direction of the first conveying roller 11 is provided with a horizontal rib 111 with both ends connected to the two side plates respectively. A set of spaced blocking members 15 are provided on the horizontal rib 111 to block the next sagger to be tested.

[0047] The positioning component 20 is vertically moved and positioned below the clearance hole 14 to lift the saggars conveyed by the first conveying roller 11 one by one and rotate the saggars for inspection. The image acquisition component 40 is correspondingly positioned above the clearance hole 14 to inspect the saggars. The erasing component 30 is straddling the mounting base. When battery material is detected adhering to the outer wall of the saggar, the erasing component 30 moves perpendicular to the conveying direction of the first conveying roller 11 to erase the battery material from the outer wall of the saggar, so as to prevent the battery material from adhering to the outer wall of the saggar for a long time and affecting the heat transfer performance of the saggar.

[0048] like Figures 1-6As shown, the positioning component 20 is used to receive the crucibles conveyed by the first conveying roller 11 and lift the crucibles for inspection. The positioning component 20 includes a second motor, a lifting shaft, a support plate 21, a limiting plate 22, and a moving plate 23. The second motor is located below the distribution track of the first conveying roller 11 and is fixedly connected to the ground or a fixed frame. The output end of the second motor is vertically upward and directly below the center of the clearance hole 14. The lifting shaft is coaxially located at the output end of the second motor. The lifting shaft can be a pneumatic lifting shaft or an electric lifting shaft.

[0049] like Figures 3-4 As shown, the pallet 21 has a square structure, and the outer dimensions of the pallet 21 are smaller than the inner wall dimensions of the clearance hole 14. The center of the bottom surface of the pallet 21 is connected to the movable end of the lifting shaft. The pallet 21 has stepped holes 211 in the middle of its four sides. The larger end of the stepped hole 211 faces upward and the smaller end faces downward. The end face of the connection between the larger end and the smaller end of the stepped hole 211 has a U-shaped structure with the opening facing the center of the pallet 21.

[0050] The limiting plate 22 is rotatably disposed within the stepped hole 211, and the outer dimensions of the limiting plate 22 are adapted to the large end dimensions of the stepped hole 211. The two ends of the limiting plate 22 facing the center of the support plate 21 are rotatably connected to the large end of the stepped hole 211 by connecting pins, and a torsion spring is provided at the connection point so that the side of the limiting plate 22 away from the center of the support plate 21 maintains a tendency to rotate towards the end face of the connection between the large end and the small end of the stepped hole 211, thereby allowing the limiting plate 22 to be accommodated within the large end of the stepped hole 211.

[0051] The projection of the outer side of the large end of the stepped hole 211 onto the conveying track of the first conveying roller 11 falls into the side of the horizontal rib 111 facing the clearance hole 14. The blocking member 15 includes a vertical pin 151, a blocking block 152, and a first spring 153. The vertical pin 151 is vertically inserted through the horizontal rib 111. The blocking block 152 has a right-angled trapezoidal cross section with its hypotenuse facing the material feeding direction of the first conveying roller 11. The upper end of the blocking block 152 abuts against one side of the bottom surface of the support plate 21. The first spring 153 is inserted through the outer wall of the vertical pin 151, and the upper end of the first spring 153 abuts against the blocking block 152, while the lower end abuts against the top surface of the horizontal rib 111.

[0052] like Figures 5-8 As shown, the bottom surface of the support plate 21 is provided with two vertically downward extending slide rods 212, and the two slide rods 212 are symmetrically arranged on both sides of the lifting shaft. The slide rods 212 have an inverted T-shaped structure, and the upper end of their vertical part is connected to the bottom surface of the support plate 21. The moving plate 23 is coaxially arranged below the support plate 21 and passes through the slide rods 212. The slide rods 212 are fitted with a second spring 213. The upper end of the second spring 213 abuts against the bottom surface of the support plate 21, and the lower end abuts against the top surface of the moving plate 23.

[0053] like Figure 6As shown, when the foremost crock of the first conveyor roller 11 is fully inserted into the pallet 21, and the side of the crock facing the material inlet direction of the first conveyor roller 11 moves past a limiting plate 22 on the pallet 21 facing the material inlet direction of the first conveyor roller 11, the next crock enters the pallet 21 and covers the area between the side of the pallet 21 facing the material inlet direction of the first conveyor belt 11 and the limiting plate 22 facing the material inlet direction of the first conveyor roller 11. At this time, the lifting shaft moves vertically upward, causing the next crock to tilt and slide out of the pallet 21 under the action of gravity. As the lifting shaft rises, the pallet 21 releases the pressure on the blocking block 152, allowing the blocking block 152 to move vertically upward under the action of the first spring 153, thereby blocking the next crock.

[0054] like Figure 3 , Figure 5 , Figures 7-8 As shown, a top strip 231 is vertically provided on the top surface of the moving plate 23, and the top strip 231 corresponds to the stepped hole 211 and is located below the stepped hole 211. When the moving plate 23 moves vertically upward, the top strip 231 is used to pass vertically upward through the stepped hole 211 so that the limiting plate 22 rotates upward around the connecting pin so that the limiting plate 22 is close to the outer wall of the sagger on the support plate 21 to limit the sagger and prevent the sagger from shifting during the testing process.

[0055] like Figure 1 , Figure 7 , Figure 9 As shown, the erasing assembly 30 includes a frame 31, a movable base 32, a wedge block 33, a strip base 34, a C-shaped frame 35, and a second linear mechanism 37. The frame 31 is mounted on the mounting base. The four corners of the bottom of the frame 31 are vertically connected to the mounting base with legs positioned on both sides of the first linear mechanism 16. The second linear mechanism 37 is located on the top surface of the frame 31, with its output end facing the direction of the first conveying roller 11. The movable base 32 is located on the second linear mechanism 16. The bottom surface of the movable seat 32 at the output end of the mechanism 37 is slidably connected to the top surface of the frame 31. The wedge block 33 is located on the side of the movable seat 32 away from the output end of the second linear mechanism 37. The hypotenuse of the wedge block 33 faces upward, one right-angled side is connected to the movable seat 32, and the other right-angled side is parallel to the top surface of the frame 31. An extension plate is provided at the lower end of the hypotenuse of the wedge block 33 in the inclined direction. An arc-shaped opening 331 is provided at the end of the extension plate away from the wedge block 33. The diameter of the arc-shaped opening 331 is adapted to the outer diameter of the lifting shaft.

[0056] The strip seat 34 is located on the top plate surface of the movable seat 32 and above the end of the movable seat 32 away from the wedge block 33. The length direction of the strip seat 34 is consistent with the output direction of the second linear mechanism 37. The top surface of the strip seat 34 is recessed and a groove 341 is provided. A guide rod 342 is provided along the length direction of the groove 341 and accommodated in the groove 341. A third spring 343 is sleeved on the guide rod 342.

[0057] C-shaped frame 35 is located on the top surface of strip seat 34, and the opening of C-shaped frame 35 faces the direction of the first conveying roller 11. A slider 352 is provided on the lower horizontal section of C-shaped frame 35. The slider 352 is slidably sleeved on guide rod 342 and slidably engaged with slide groove 341 so that the slider 352 is located in the direction of guide rod 342 facing the first conveying roller 11. The third spring 343 is located in the direction of guide rod 342 away from the first conveying roller 11 so that one end of the third spring 343 abuts against slider 352 and the other end abuts against the end of slide groove 341 away from wedge block 33.

[0058] A wiping brush 351 is vertically rotatably provided at the opening of the C-shaped frame 35. The wiping brush 351 includes a vertically arranged rotating shaft, the outer wall of which is covered with bristles. The two ends of the rotating shaft are rotatably connected to the horizontal parts at the upper and lower ends of the C-shaped frame 35, respectively. The upper end of the rotating shaft passes through the upper horizontal part of the C-shaped frame 35 and is connected to the output shaft of the first motor 354 mounted on the C-shaped frame 35.

[0059] A set of spaced slotted bracing plates 353 are provided on the vertical side of the C-shaped frame 35 away from the opening, and the bracing plates 353 are located on both sides of the top surface of the slide groove 341 to improve the stability of the C-shaped frame 35 when it moves.

[0060] like Figures 10-13 As shown, when battery material is detected adhering to the outer wall of the sagger, the second linear mechanism 37 pushes the moving seat 32 to move in the direction of the first conveying roller 11, thereby causing the wedge block 33 and the strip seat 34 to move synchronously in the direction of the lifting shaft.

[0061] On the one hand, under the action of the inclined side of the wedge block 33, the moving plate 23 is pushed to move vertically upward and approach the bottom of the support plate 21 so that the top bar 231 passes through the corresponding stepped hole 211. At this time, the limiting plate 22 moves vertically upward under the action of the top bar 231, so that the limiting plate 22 is close to the corresponding outer wall of the sagger, thereby limiting the sagger. In order to facilitate the top bar 231 to push the limiting plate 22 to rotate, the top surface of the top bar 231 is provided with an inclined surface that is inclined downward in the direction of the rotation axis of the support plate 21.

[0062] On the other hand, the bristles of the wiping brush 351 are brought close to the outer wall of the sagger, and then the first motor 354 is started so that the first motor 354 drives the shaft to rotate, thereby wiping the battery material attached to the outer wall of the sagger by the bristles of the wiping brush 351, so as to avoid the battery material from adhering to the outer wall of the sagger and affecting the heat transfer performance of the sagger.

[0063] like Figure 1 , Figure 7 , Figure 13 As shown, the image acquisition component 40 includes a mounting bracket 41 and cameras 42. The mounting bracket 41 has an inverted U-shaped structure and is fixedly mounted on the bottom surface of a frame. The mounting bracket 41 includes a first vertical arm 411 and a second vertical arm 412. The first vertical arm 411 is located above the long axis of the first conveying roller 11 in the conveying direction and is coaxial with the lifting shaft. The second vertical arm 412 is located above the second conveying roller 12 and outside the distribution track of the first conveying roller 11. Three cameras 42 are provided and are located on the lower end side of the first vertical arm 411, the lower end of the first vertical arm 411, and the side of the second vertical arm 412 facing the first vertical arm 411, respectively. They are used to acquire images of the inner and outer circumferences of the sagger and the bottom surface of the sagger. The acquisition results are then fed back to the upper position for image comparison and analysis to determine whether there are cracks on the inner and outer walls of the sagger and whether battery material is attached to the outer wall of the sagger.

[0064] Preferred, such as Figure 16 As shown, when battery material is attached to the outer wall of the sagger, in order to prevent the battery material wiped by the wiping brush 351 from dispersing into the air and then adhering to the camera 42, affecting the shooting effect of the camera 42 and causing misjudgment, a portal frame 36 is provided across the C-shaped frame 35. The lower ends of the portal frame 36 are respectively provided with connecting plates that connect to the lower horizontal part of the C-shaped frame 35. A cantilever 361 is provided at the center of the horizontal part of the portal frame 36. The extended end of the cantilever 361 extends outward to the outside of the wiping brush 351, and an air extraction hood 362 is provided at the lower end of the cantilever 361 so that the projection of the air extraction hood 362 on the frame 31 covers the projection of the wiping brush 351 on the frame 31, thereby sucking away and collecting the wiped battery material for secondary use.

[0065] The specific usage process is as follows:

[0066] The crucibles to be tested are placed sequentially on the first conveyor roller 11 along its conveying direction. When the crucible at the very front of the first conveyor roller 11 enters the top surface of the tray 21, and the next crucible after the one at the very front of the conveying direction enters the tray 21 and corresponds to the blocking block 152, the lifting shaft extends vertically upward to move the crucibles that have fully entered the tray 21 vertically upward and closer to the lower end of the mounting bracket 41. When the crucibles enter the field of view of the cameras 42 on the sides of the first vertical arm 411 and the second vertical arm 412, the cameras 42 begin image acquisition, and the second motor performs image acquisition at the cameras 42. The gap is rotated so that the lifting shaft drives the pallet 21 to rotate, so that the saggers on the pallet 21 rotate synchronously. This allows the cameras 42 on the sides of the first vertical arm 411 and the second vertical arm 412 to capture images of the inner and outer walls of the saggers respectively. The camera 42 at the lower end of the first vertical arm 411 captures images of the bottom of the inner wall of the sagger and feeds the results back to the upper position for comparison. If a crack is detected, the detection stops. The second motor drives the lifting shaft to rotate to the initial position and vertically downward so that the pallet 21 is reset. The first linear mechanism 16 is activated so that the first linear mechanism 16 pushes the cracked sagger onto the second conveyor roller 12 for output.

[0067] like Figures 10-13 As shown, if the camera 42 on the side of the second vertical arm 412 detects battery material attached to the outer wall of the sagger, the second linear mechanism 37 is activated, so that the second linear mechanism 37 pushes the moving seat 32 to move in the direction of the first conveying roller 11. When the arc-shaped notch 331 is aligned with the outer wall of the lifting shaft, the second linear mechanism 37 stops moving. At this time, the moving plate 23 moves vertically upward under the action of the inclined side of the wedge block 33, and the lower end of the inclined side of the wedge block 33 transitions to the top surface of the moving seat 32, so that the bottom surface of the moving plate 23 keeps in contact with the top surface of the moving seat 32. As the moving plate 23 moves vertically upward, the top bar 231 moves vertically upward into the corresponding stepped hole 211, and pushes the limiting plate 22 in the stepped hole 211 vertically upward until the limiting plate 22 is close to the corresponding outer wall of the sagger, thereby limiting the outer wall of the sagger.

[0068] At this point, the outer brush of the wiping brush 351 contacts the outer wall of the sagger, and the first motor 354 is activated to rotate the wiping brush 351, thereby wiping away the battery material on the outer wall of the sagger. Simultaneously, the second motor drives the lifting shaft to rotate, thus rotating the sagger. Figures 14-17As shown, when the diagonal of the tray 21 corresponds to the axis of rotation of the wiping brush 351, the tray 21 pushes the lower horizontal part of the C-shaped frame 35, so that the slider 352 at the lower end of the C-shaped frame 35 moves away from the sagger along the guide rod 342, so as to avoid the C-shaped frame 35 interfering with the rotation of the tray 21 and to ensure that the bristles of the wiping brush 351 are always in contact with the outer wall of the sagger, thereby completing the wiping of the battery material on the outer wall of the sagger, avoiding the battery material from adhering to the outer wall of the sagger for a long time, affecting the sagger test results, and ensuring the heat transfer performance of the sagger.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
