Technical Field

[0002] Alumina sintering is carried out by loading alumina into a crucible and then sending it into a kiln for sintering; the crucible currently used is a rectangular structure, including a rectangular cover and a rectangular trough, and the rectangular cover covers the rectangular trough; the crucible is sent into the kiln through a conveyor line; for the existing large-scale alumina sintering, the crucibles on the conveyor line need to be stacked and stacked, so that before entering the kiln for sintering, the stacked crucibles need to be in a flat state on all sides. Currently, they are corrected manually, which is time-consuming, labor-intensive and inefficient. There is no systematic and clear equipment on the market to perform crucible leveling. Crucible stacking is placed on the conveyor line, which is time-consuming, labor-intensive, and inefficient, and cannot meet the needs of alumina sintering production lines; used crucibles need to be cleaned and reused, and the used crucibles need to be cleaned on all sides. In the past, manual cleaning was usually performed, which was time-consuming and labor-intensive.

[0016] 4. The rectangular cover body is automatically flipped 180 degrees by the flipping part, so that the inner side of the rectangular cover body that needs to be cleaned faces upward, which is convenient for the subsequent roller brush of the cleaning part to perform effective cleaning. It is safe, reliable, convenient and fast, does not require manual labor, and meets the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Refer to the attached Figure 1-22 , a kiln external circulation automatic production line, which includes a kiln 90, a conveying line body 10, a crucible cleaning mechanism 60, a crucible stacking mechanical gripper mechanism 600, a stacked crucible surrounding leveling mechanism 20 and a crucible cover flipping and cleaning mechanism, the conveying line body 10 includes a line body 1001, a line body 2 1002 and a line body 3 1003, the line body 1001 is designed as a circulating line body, the kiln 90 is installed in the middle position of one side of the line body 1001, the line body 2 1002 and the line body 3 1003 are installed in parallel on the inner side of the line body 1 1001, and crucible stacking mechanical gripper mechanisms are installed on both sides of the line body 2 1002 and the line body 3 1003, respectively. A crucible stacking leveling mechanism 20 is installed at a corner of the line body 1 near the feeding end of the kiln 90, and a crucible cleaning mechanism 60 is installed at one end of the line body 1 near the discharging end of the kiln 90. A crucible cover flipping and cleaning mechanism is installed on the line body 3 1003, and the line body 2 1002 is designed as a crucible cover return line; Refer to the attached Figure 2-8, a cleaning mechanism 60 around the crucible includes a conveyor line body 10, a frame, a driving mechanism 40, a side brush 1, and a lifting and rotating assembly 50. The frame is installed above and on both sides of the conveyor line body 10, and the driving mechanism 40 is installed on the upper end of the frame. There are four side brushes 1. Two side brushes 1 are respectively designed on the conveyor line body 10 near the two sides. The upper ends of the two side brushes 1 on each side are rotatably installed on the frame. The driving mechanism 40 drives and connects the four side brushes 1. The lifting and rotating assembly 50 is installed on the conveyor line body 10 below the frame. The four side brushes 1 are located around the top of the lifting and rotating assembly 50.

[0040] The frame is a rectangular frame, which includes a side frame 201 and a cross frame 202. A side frame 201 is installed on each side of the conveyor line body 10. The upper ends of the two side frames 201 correspond to the positions on both sides of the cross frame 202 respectively. The driving mechanism 40 includes a driving motor 401, a gear pair, a side pulley 402 and a synchronous belt 403. The driving motor 401 is installed on the cross frame 202. The driving motor 401 drives the gear pair. The upper end of the side brush 1 is coaxially installed at the four corners of the cross frame 202 through the brush rod and the side pulley 402. The two sides of the gear pair are synchronously driven to connect a side pulley 402 on each side, and the other side pulley 402 on each side is synchronously driven and connected to the side pulley 402 on the same side through the synchronous belt 403; the lower end of the brush rod is equipped with a side brush 1.

[0041] The gear pair includes a main gear 404 and a driven gear 405. The main gear 404 is rotatably mounted on the lower driving end of the driving motor 401, and the upper end of the driven gear 405 is rotatably mounted on the cross frame 202. An intermediate pulley 406 is coaxially mounted on the lower ends of the main gear 404 and the driven gear 405. The main gear 404 and the driven gear 405 are meshed and installed. A side pulley 402 is also coaxially mounted below the side pulleys 402 on both sides of the driving motor 401. The main gear 404 and the driven gear 405 are respectively driven and connected to the side pulleys 402 on the adjacent side through the intermediate pulley 406 at the lower end through the synchronous belt 403. The driving motor drives the lower main gear and the intermediate pulley below it, and the main gear drives the driven gear and the intermediate pulley below it. The driven gear rotates in the opposite direction to the main gear, and the two intermediate pulleys drive the side pulleys on both sides through the synchronous belt. In this way, the side pulleys on both sides drive the coaxially installed side pulleys, brush rods, and side brushes below to rotate synchronously. At the same time, the side below drives the side pulleys installed on the same side and the coaxially installed brush rods and side brushes through the synchronous belt again. In this way, the four side brushes are driven to rotate simultaneously, but the side brushes on the left and right sides work in opposite rotation directions.

[0042] The lifting and rotating assembly 50 includes a lifting cylinder 501, a rotating motor 502, a cross bracket 503, a lifting plate 504 and a U-shaped mounting plate 505. The U-shaped mounting plate 505 is installed below the conveyor line body 10. The lifting cylinder 501 is installed below the bottom of the U-shaped mounting plate 505 and the telescopic end of the lifting cylinder 501 passes through the bottom of the U-shaped mounting plate 505. The lifting plate 504 is located above the bottom of the U-shaped mounting plate 505 and the lifting plate 504 is installed on the telescopic end of the lifting cylinder 501. The rotating motor 502 is installed on the lifting plate 504. The upper driving end of the rotating motor 502 is connected to the lower end of the cross bracket 503. The cross bracket 503 is located at the upper end of the conveyor line body 10, and an avoidance groove 506 for the cross bracket 503 to be raised and lowered is reserved in the middle of the conveying roller of this section of the conveyor line body 10. When the crucible is transported to the lifting and rotating assembly through the conveyor line, the conveyor line stops working, and the cross bracket is normally located below the conveyor roller of the conveyor line and in the avoidance groove, ensuring that the crucible can be transported and walked on the conveyor roller of the conveyor line. The avoidance groove also ensures that the cross bracket has a hidden position to avoid interference; when the crucible that has been cleaned on both sides reaches the top of the cross bracket and needs to be rotated 90 degrees, the lifting cylinder lifts the lifting plate and the rotating motor, cross bracket, and crucible installed thereon to a certain rotation avoidance height, and the rotating motor then drives the cross bracket to rotate the crucible above 90 degrees, so that the uncleaned sides of the crucible are replaced with the cleaned sides, and the lifting cylinder descends and resets again, and the adjusted crucible continues to be transported to clean the remaining two sides.

[0043] like Figure 5 The frame is also equipped with a suction hood 203, transparent observation windows are sealed on the front and rear sides of the frame, and the left and right sides of the frame are designed as passages for the crucible to pass through. A suction fan is also designed on the upper end of the suction hood to extract air, and the air enters from the passages on both sides of the frame and is then transported from the suction hood to the dust collection device to avoid dust overflowing and polluting the environment during cleaning.

[0044] A stopping mechanism 30 is also installed on the rear side of the lifting and rotating assembly 50, and the stopping mechanism 30 includes a U-shaped plate 31, a lifting plate 32, a stopping cylinder 33, and a vertical plate 34. The U-shaped plate 31 is installed under the conveying line body 10, and the stopping cylinder 33 is installed at the lower end of the U-shaped plate 31. The telescopic end of the stopping cylinder 33 passes through the bottom of the U-shaped plate 31, the lifting plate 32 is located above the bottom of the U-shaped plate 31 and the lower end of the lifting plate 32 is connected to the telescopic end of the stopping cylinder 33, and the vertical plate 34 is vertically installed on the upper end of the lifting plate 32. The vertical plate of the stopping mechanism normally extends out of the conveyor roller of the conveyor line body to a certain height, blocking the route of the crucible conveyor line body to assist in the positioning of the lifting and rotating assembly. After the lifting and rotating assembly rotates the crucible 90 degrees, the stopping cylinder of the stopping mechanism controls the lifting plate and the vertical plate to descend together to avoid the crucible and ensure that the rotated crucible can pass normally. After the crucible passes, the stopping mechanism resets again, and the vertical plate continues to block the rear side of the lifting and rotating assembly until the next crucible is in place, and this process is repeated.

[0045] Rotating rollers 35 are respectively arranged on both sides of the upper end of the vertical plate 34. The rotating roller design is conducive to the passage of the crucible above, minimizes the descending stroke of the vertical plate, and avoids unnecessary interference.

[0046] When the cleaning mechanism around the crucible is in use, when the crucible 2 that needs to be cleaned is sent to the workstation of the present invention through the conveyor line body, the left and right side brushes near the inlet position rotate in opposite directions under the action of the driving mechanism, and the left and right sides of the passed crucible 2 are automatically cleaned, and the crucible 2 moves on the conveyor line body while being cleaned by the side brushes on both sides. After the cleaning of both sides is completed, the front end of the crucible 2 hits one side of the vertical plate of the stopping mechanism, and the crucible 2 cannot move forward. After the auxiliary corresponding part reaches the position of the lifting and rotating assembly, the crucible 2 is automatically lifted up and rotated 90 degrees and then put down. At this time, the stopping mechanism also controls the vertical plate to sink and avoid, and the crucible 2 continues to be transported forward through the conveyor line body, and passes through the left and right side brushes near the exit position again. Under the action of the driving mechanism, it also rotates in opposite directions to automatically clean the left and right sides of the rotated crucible 2 that has passed. The crucible 2 is automatically cleaned around, thereby improving efficiency and meeting production needs.

[0048] The curved connecting plate 604 is designed to be a V-shaped plate. The curved connecting plate structure saves space when it is extended and contracted, and cooperates with the middle rectangular rotating plate to realize synchronous driving of the slide plate assembly on the four sides to ensure stable clamping.

[0049] The clamping plate 606 is designed as a vertical rectangular plate, and a protective pad 6061 is installed on the inner side of the clamping plate 606. The protective pad 6061 is a polyurethane pad. The protective pad design increases friction and helps reduce damage to the crucible.

[0050] The slider assembly 607 includes a transverse plate 6071, an I-shaped slider 6072, and a guide wheel 6073. One end of the transverse plate 6071 is installed on the upper end of the I-shaped slider 6072, and the other end of the transverse plate 6071 is rotatably connected to one end of the curved connecting plate 604, and the upper ends of any two oppositely installed transverse plates 6071 are respectively connected to the two ends of the gripper cylinder 603. Four sliding grooves 6010 for four I-shaped sliders 6072 to slide are opened on the mounting plate 608. Two guide wheels 6073 are respectively installed on both sides of the upper end of the I-shaped slider 6072, and the guide wheels 6073 roll on the mounting plate 608.

[0052] When the mechanical gripper mechanism for stacking crucibles is in use, the mechanical arm clamps the crucibles conveyed by the conveyor line of the previous process one by one through the device of the present invention, and places them on the conveyor line of the next process to stack 6 crucibles; the mechanical arm controls the grasping frame to be located above the crucible, and the grasping cylinder stretches, and synchronously controls the sliding components on both sides to stretch to both sides. Since the four corners of the rectangular rotating seat are synchronously connected to the sliding components on the four sides through four curved connecting plates, the sliding components on both sides react to the rectangular rotating plate in the middle, and the rectangular rotating plate controls the synchronous stretching of the remaining sliding components on both sides, so that the four sliding components are synchronously The clamping plate below is driven to open outwards, and the robotic arm controls the grabbing frame to buckle on the outer side of the crucible, and the clamping plate is located around the crucible at the same time; when clamping begins, the grabbing cylinder contracts, and similarly controls the synchronous contraction of the sliding components around, and synchronously controls the clamping plate to clamp toward the middle, and the guide rod and guide sleeve cooperate to stabilize the clamping and moving forward to prevent the jaws from running off and causing jamming. The clamping block is provided with a polyurethane pad, which increases the friction and helps reduce damage to the crucible; after clamping is completed, the robotic arm controls the device of the present invention to move to the designated stacking position after grasping, and then repeats the above-mentioned stretching action to put down the stable crucible. The four sides of the present invention clamp synchronously together, with good clamping force, accurate and efficient clamping accuracy. This crucible stacking mechanical gripper mechanism can also be used for destacking.

[0053] Refer to the attached Figure 14-17 , a leveling mechanism 20 around the stacked crucible includes a conveyor line body 10, a side rectangular frame 21, a transverse rectangular frame 22, a leveling cylinder 23, and a right-angled leveling push plate 24. The two sides of the transverse rectangular frame 22 are installed above the two sides of the conveyor line body 10 through a side rectangular frame 21, and a leveling cylinder 23 is installed at the four corners below the transverse rectangular frame 22. The leveling cylinder 23 is designed to be horizontally installed at an angle of 90 degrees to the conveyor line body 10, and the front telescopic end of the leveling cylinder 23 is connected to a vertically designed right-angled leveling push plate 24.

[0054] The four corners of the transverse rectangular frame 22 are respectively installed with a diagonal brace 221, and the sides of the lower end of the side rectangular frame 21 are respectively installed with a right-angled trapezoidal horizontal brace 222 near the side of the conveyor line body 10. Two vertical braces 223 are installed between the diagonal brace 221 and the right-angled trapezoidal horizontal brace 222 below. A mounting plate 224 is installed on the two vertical braces 223, and a leveling cylinder 23 is installed on the outer side of the mounting plate 224. The telescopic end of the leveling cylinder 23 passes through the mounting plate 224, and the right-angled leveling push plate 24 is located on the inner side of the mounting plate 224. Two guide rods 25 are also installed on the outer side of the right-angled leveling push plate 24. Two guide sleeves 26 are respectively installed on the outer side of the mounting plate 224, and the guide rods 25 are slidably located in the corresponding guide sleeves 26.

[0055] The right-angled leveling push plate 24 also includes a U-shaped connector 241 and a protective pad 242. A protective pad 242 is installed on the two right-angled sides of the inner side of the right-angled leveling push plate 24, and a U-shaped connector 241 is installed on the outer side of the right-angled leveling push plate 24. The ends of the two side edges of the U-shaped connector 241 are respectively designed as bending edges 243. The two sides of the U-shaped connector 241 are connected to the outer sides of the right-angled sides of the right-angled leveling push plate 24 through the bending edges 243; the bottom outer side of the U-shaped connector 241 is connected to the leveling cylinder 23.

[0056] The protection pad 242 is designed as a rubber pad.

[0057] The stacked crucible leveling mechanism 20 also includes a stop mechanism 30, which is located below the horizontal rectangular frame 22. The stop mechanism 30 includes a U-shaped plate 31, a lifting plate 32, a stop cylinder 33, a vertical plate 34, and a limit switch 35. The U-shaped plate 31 is installed below the conveyor line body 10, and a stop cylinder 33 is installed at the lower end of the U-shaped plate 31. The telescopic end of the stop cylinder 33 passes through the bottom of the U-shaped plate 31. The lifting plate 32 is located above the bottom of the U-shaped plate 31 and the lower end of the lifting plate 32 is connected to the telescopic end of the stop cylinder 33. The upper end of the lifting plate 32 is vertically installed with a vertical plate 34, and the upper end of the vertical plate 34 is installed with a limit switch 35. The vertical plate of the stopping mechanism normally extends a certain height from between the conveying rollers of the conveyor line body to stop the conveyed crucible, and senses and transmits the signal that the crucible is in place through the limit switch. The device of the present invention then performs a leveling operation. After the leveling operation is completed, the stopping mechanism controls the vertical plate to descend through the stopping cylinder to avoid the crucible until the limit switch separates from the crucible. At this time, the conveyor line body continues to convey the crucible forward, and confirms that the crucible has been conveyed away through the delay design or the stroke switch. This is the prior art, and the present invention is briefly described. The stopping mechanism controls the vertical plate to rise and reset, waiting for the next stopping work.

[0058] The vertical plate 34 is provided with a notch 341 for avoiding the limit switch, and rotating rollers 342 are respectively arranged on both sides of the upper end of the vertical plate 34. The notch is designed to facilitate the rotation of the contact above the limit switch without interference; the rotating roller helps the crucible to pass from above, avoiding unnecessary interference.

[0059] When the leveling mechanism around the stacked crucibles is in use, the mechanical arm stacks the crucibles one by one, and the stacked crucibles (usually six in a group) are then transported to the workstation of the present invention through the conveyor line body. The vertical plate of the stop mechanism is normally higher than the height of the conveying roller of the conveyor line body. When the crucible reaches the front position of the vertical plate, the crucible will touch the limit switch. After the limit switch senses that the stacked crucibles are in place, the conveyor line body stops conveying. The leveling cylinders installed at the four corners of the device extend synchronously to control the right-angled leveling push plate at the front end to push toward the middle. The protective pads on the inner side of the right-angled leveling push plate are pressed against the outside of the four corners of the crucible, and the four corners of the crucible are synchronously squeezed to make them level up and down. At this time, the stop cylinder of the stop mechanism contracts to control the vertical plate to descend, and the vertical plate is lower than the conveying roller of the conveyor line body. At the same time, the limit switch is separated from the crucible, and the conveyor line body continues to convey, so that it enters the kiln for sintering and maintains the best position.

[0060] Refer to the attached Figure 18-22, the crucible cover flipping and cleaning mechanism comprises a conveying line body 10, a flipping part 70, and a cleaning part 80. The input end of the conveying line body 10 is equipped with the flipping part 70, and the output end of the conveying line body 10 is equipped with the cleaning part 80; the flipping part 70 comprises a rotating motor 701, a rotating shaft 702, a rotating rectangular frame 703, a clamping plate 704 and a cross brace 706. Both ends of the rotating shaft 702 are rotatably mounted on the conveying line body 10, and the rotating rectangular frame 703 is mounted in the middle of the rotating shaft 702. Two cross braces 706 are mounted on the upper end of the conveying line body 10, and an avoidance groove 707 for the rotating rectangular frame 703 to rotate is formed between the two cross braces 706. Two clamping clamps 704 are mounted on one end of the rotating rectangular frame 703, and a notch 708 for the crucible cover to enter is reserved at the end. A counterweight block 709 is mounted on the other end of the rotating rectangular frame 703. A rotating motor 701 is installed below the conveyor line body 10, and the rotating motor 701 drives and connects any end of the rotating shaft 702; the cleaning part 80 includes a roller brush 801, a rubber roller 802, a driving motor 803, and a rectangular frame 804; a rectangular frame 804 is installed above the conveyor line body 10, and multiple groups of rubber rollers 802 and roller brushes 801 are alternately installed in the rectangular frame 804 in sequence, and the two ends of the rubber rollers 802 and the roller brushes 801 rotate on the two side plates of the rectangular frame 804 respectively, and a driving motor 803 is installed on the outer side of one side plate of the rectangular frame 804, and the driving motor 803 is connected to one end of the multiple groups of rubber rollers 802 and the roller brush 801 through multiple groups of pulleys and synchronous belts; a gap for the crucible cover to pass is left between the multiple groups of rubber rollers 802 and the roller brush 801 and the conveying rollers of the conveyor line body 10. It is a prior art that the rotating motor drives the rotating shaft to rotate through a sprocket chain, and the present invention is not limited to this driving structure.

[0061] The clamping plates 704 are designed to be two, one above the other. The outer sides of the two clamping plates 704 are fixed on the rotating rectangular frame 703 through the clamping cylinders 710. The front telescopic end of the clamping cylinders 710 is connected to the middle position of the back side of the clamping plates 704. The rear end of the clamping cylinders 710 is installed on the upper or lower side of the rotating rectangular frame 703 through the U-shaped plate 7041. The clamping plates 704 can move up and down and are located in the rectangular groove that runs through the middle of the rotating rectangular frame 703. The notch 708 for the crucible cover to enter is connected to the rectangular groove. The clamping cylinder controls the effective clamping action of the clamping plates to meet the clamping requirements.

[0062] Conveying rollers 101 are installed between the outer sides of the two horizontal braces 706 and the two side plates of the conveying line body 10. Since the turning action of the turning part requires an avoidance groove, the longer conveying rollers of the conveying line body are adjusted to short and narrow conveying rollers, which saves space while still having the original conveying drive function. The length of the conveying roller can be adjusted according to actual needs, and the main purpose is to be able to convey the rectangular cover of the crucible without interfering with the action of the turning part.

[0063] The back side of the clamping plate 704 is also equipped with guide rods 7042 near both sides, and the U-shaped plate 7041 is equipped with corresponding guide sleeves for guiding the guide rods 7042. The guide sleeve design of the guide rod 7042 ensures that the clamping plate is stable and safe. A polyurethane gasket is also installed on the inner side of the clamping plate for protection.

[0064] A sensor switch 711 is installed on the front and rear sides of the two cross braces 706. The front and rear sensor switches are designed to ensure that the flip unit can effectively monitor the entry and exit of the rectangular cover 100 of the crucible and move in an orderly manner.

[0065] The rectangular frame 804 of the cleaning section 80 is covered with a cover plate 805, and an inverted U-shaped cover 806 is also installed on the conveying line body 10 on both sides of the cleaning section 80, and a U-shaped groove 807 is designed below the cleaning section 80 and the U-shaped covers on both sides, and the U-shaped groove is installed below the section of the conveying line body 10. The cover plate, the inverted U-shaped cover and the U-shaped groove below are designed to prevent dust from overflowing. The dust eventually settles in the U-shaped groove and can be cleaned regularly. The length of the inverted U-shaped cover is designed to ensure that dust will not overflow from both ends. The upper end of the inverted U-shaped cover can also be designed with an openable flap to facilitate observation and cleaning operations. The cover plate is designed to be a flip cover for easy opening.

[0066] The upper and lower layers of the mouth of the slot 708 for the crucible cover to enter are respectively designed to be equipped with a cylindrical buffer positioning bracket 712, the upper end of the cylindrical buffer positioning bracket 712 is installed at the upper and lower positions of the mouth through a connecting piece, and the lower end of the cylindrical buffer positioning bracket 712 can be correspondingly supported on the brackets 102 on both sides of the conveyor line body 10.

[0067] When the crucible cover flipping and cleaning mechanism is in use, the mechanical arm takes the rectangular cover 100 of the crucible off the rectangular slot of the crucible, and puts it on the designated conveyor line to be transported to the device of the present invention for cleaning. The rectangular cover 100 transported by the conveyor line arrives at the flipping part, and the induction switch senses the signal that the rectangular cover 100 is in place. The rotating rectangular frame of the flipping part is normally in a horizontal state, and the slot for the crucible cover to enter is flush with the conveying path of the conveyor line, ensuring that the rectangular cover 100 is transported to the slot for the crucible cover to enter along the conveying rollers on both sides of the conveyor line. At this time, the upper and lower clamping cylinders synchronously drive the upper and lower clamping plates to clamp the crucible cover, and the rotating motor controls the rotating rectangular frame to rotate 180 degrees through the rotating shaft, so that the rectangular cover 100 is rotated 180 degrees. The inner side of the rectangular cover plate faces upward, and the upper and lower clamping cylinders control the clamping plates to release the clamping, and the rectangular cover plate is transported to the cleaning part by the conveying roller of the conveyor line body. When the induction switch senses that the rectangular cover plate leaves the slot for the crucible cover to enter, the flipping part reverses the rotation to reset; when the rectangular cover plate enters the cleaning part, the rubber roller of the cleaning part and the conveying roller of the conveyor line body clamp the rectangular cover plate and pull it forward to make the rectangular cover plate pass smoothly between the roller brush and the conveying roller of the conveyor line body, and clean the inner side of the rectangular cover plate while passing through the roller brush. Through the action of multiple groups of rubber rollers and roller brushes, the inner side of the rectangular cover plate of the crucible is effectively cleaned, and then the cleaned rectangular cover plate is sent to the next process through the conveyor line body.

[0068] The entire process of the kiln external circulation automatic production line of the present invention is: The empty crucible is filled with materials by vibrating and feeding, and the materials are transmitted through the line body to the vibrating leveling mechanism for leveling; When the crucible reaches this station, the universal lifting mechanism at the bottom of the line body lifts the crucible to the shaking position, the side clamping claw mechanism cylinder clamps, the top plate and the crucible fit tightly, the universal lifting cylinder drops back to the original position, the vibration shaking servo motor rotates the eccentric shaft to drive the crucible to shake eccentrically, so that the material is shaken to be even and flat, the universal lifting mechanism lifts it to the position, unclamps the clamping claw cylinder, and drops it to the conveyor line; The crucible reaches the positioning position composed of the universal stop mechanism and the universal lifting mechanism, and is lifted up by the palletizing robot to clamp the crucible and place it in the palletizing position; The remaining pallets are picked up by the palletizing robot and placed on the universal lifting mechanism at the tail of the second line body, and the conveyor line transports them to the middle of the second line body; the mobile visual inspection and defective and good product warehouse areas are visually inspected. If the pallet is qualified, it will continue to run to the head of the conveyor line [disassembly robot]. If the pallet is unqualified, it will be sent to the universal defective product warehouse by the visual robot gripper, and then the good pallet will be clamped from the pallet good product warehouse to be added to the second line body until it is transported to the head; When 6 crucibles are stacked, the universal lifting mechanism at the tail of the triad lifts up the lid, which is then clamped by the stacking robot for stacking and capping. After a pile of crucibles is stacked, they are leveled on all sides. After reaching the position, the four-claw cylinders are connected through the front and rear sensors to clamp the four sides of the stack of crucibles, which further checks the position of the stacked crucibles layer by layer to prevent them from tipping over in the kiln. This stack of crucibles is sent to the kiln for baking by the conveyor line. After baking, this stack of crucibles will enter the dismantling area; The baked crucibles arrive at the dismantling area, where the dismantling robot grabs the top cover with the gripper and places it on the universal lifting mechanism of the head of the triad. The cover is sent to the first cover by the conveyor belt for cleaning. The cover is clamped and conveyed in the same direction by the bottom ceramic roller and the rubber roller on the top of the mechanism. At the same time, the brush in the middle of the roller moves in the opposite direction for cleaning to achieve the maximum cleaning effect. After cleaning, it is sent to the first cover for flipping and flipping 180°. After flipping, the cover enters the second cover for cleaning. After flipping, the inside of the cover is cleaned. After cleaning, mobile visual inspection of defective and good product warehouses is performed. After inspection, if the bottom of the flipped cover is normal, it continues to run and enters the second cover flip. The cover flips 180° and returns to the normal state at the beginning, reaching the tail of the triad, close to the stacking robot. If there is a horizontal row at the bottom of the flipped cover, it is considered a defective product and will be sent to the universal defective product warehouse by the visual robot gripper. Then, the good cover is clamped from the good cover warehouse and added to the triad until the tail of the conveyor line. After the lid is removed, the demolition robot clamps the good product tray conveyed by the second line body, places it in the unloading and demolition position, then clamps the first layer of the crucible in this stack of crucibles, clamps it to the lifting unloading and discharging position, fixes it by the crucible mold, and lifts it to the top position through the belt lifting mechanism. The translation mechanism clamps the crucible to the top of the hopper of the mobile silo, and the waiting material turning mechanism drives the crucible with material to turn over for unloading operation, and the baked material is poured into the hopper of the mobile silo. After pouring, it returns to the lifting unloading and discharging position, and the other clamping claw of the demolition robot clamps the second layer of crucible with material for standby, and the other clamping claw clamps the crucible waiting for material at the lifting unloading and discharging position, and then the crucible with material is placed to the lifting unloading and discharging position, and the lifting and waiting operation is repeated. During this spare time, the bottom of the empty crucible will be cleaned, and after cleaning, it will be placed on the tray on the unloading position. At this point, the unloading process of the crucible with material is completed; Then the empty crucible is cleaned all around. When entering, the side cleaning brush is used to clean the tray and the side of the crucible. After reaching the lifting and rotating mechanism and rotating 90°, it is cleaned all around. Then the side cleaning brush is used to clean the front and back of the tray and the crucible. The cleaning is completed. The empty crucible enters the cleaning chamber area, the universal lifting mechanism lifts the tray and the crucible, the cleaning chamber manipulator clamps the crucible and enters the cleaning chamber, the manipulator drives the crucible to rotate 180°, with the inside of the crucible facing downward, the cleaning brush mechanism inside the cleaning chamber is lifted to a suitable height, and the cleaning brush is driven by the eccentric shaft to perform eccentric movement to achieve the purpose of cleaning the inside of the crucible; The empty crucible enters the crucible and rotates to take pictures. The jack is lifted up and the servo motor drives it to rotate. The fixed camera takes pictures from the side. Then the products enter the mobile visual inspection area for defective and good products. After inspection, if there are cracks inside the crucible, it will be considered as a defective product. The visual robot gripper will send it to the general defective product warehouse, and then the good crucible will be clamped from the good crucible warehouse and added to the tray. The empty crucible is sent to the vibrating unloading machine by the conveyor line, and the cycle is completed.
