[0002] In my country's electronics and electrical, solar energy, powder metallurgy, display, water filtration and other industries, a large number of powdered non-metallic materials or rare metal powdered materials are used. These powders need to be sintered in a high-temperature furnace before being put into use. The temperature in the furnace is very high. In order to meet the needs of sintering in a high-temperature furnace, the powders need to be contained in a high-temperature sagger. In the prior art, the unloading and loading of the sagger after it is taken out of the furnace are generally done manually. The labor intensity of manual loading and unloading is high, the efficiency is low, and the dust pollution is large. The working environment of the operator is relatively poor.

The material receiving box 3312 is arranged below the material guide trough 3311, and an opening is provided at the upper end of the material receiving box 3312. The material guide trough 3311 is in the shape of a funnel with a wide top and a narrow bottom.

[0064] The material unloading clamp component 3320 includes: a flip plate 3321, a first frame 3322, a second frame 3323 and a clamping driving component 3324. The first frame 3322 and the second frame 3323 are arranged in the left and right directions, and the first frame 3322 and the second frame 3323 are respectively provided with a left clamping part and a right clamping part facing each other. The left clamping part and the right clamping part are both in an arc shape corresponding to the outer shape of the sagger. The first frame 3322 and the second frame 3323 are both slidably installed on the flip plate 3321 in the left and right directions. The clamping driving component 3324 is used to drive the first frame 3322 and the second frame 3323 to move closer to each other or away from each other. In this embodiment, the clamping driving component 3324 includes a left clamping cylinder and a right clamping cylinder. The left clamping cylinder and the right clamping cylinder are respectively connected to the first frame 3322 and the second frame 3323 in transmission connection.

[0065] The first frame 3322 and the second frame 3323 are arranged at one end of the flip plate 3321, and the other end of the flip plate 3321 is provided with a flip shaft 3325. The flip shaft 3325 is rotatably mounted on the upper front end of the material dumping frame 3340 and is located between the material receiving member 3310 and the material dumping station, and the material receiving member 3310 and the material dumping station are arranged on both radial sides of the flip shaft 3325.

[0067] The guide plate 3327 extends toward the axial direction of the clamped sagger. In the projection along the axial direction of the sagger, the shape of the guide plate 3327 corresponds to the edge shape of the sagger. When the clamping drive member 3324 drives the first frame 3322 and the second frame 3323 to clamp toward each other, the two guide plates 3327 press against each other to form a guide channel. When the sagger is turned over and poured, the sintered material in the sagger can slide along the guide channel into the guide groove 3311. In some other embodiments, the guide plate 3327 can also be set on the flip plate 3321.

[0068] In a further embodiment, referring to Figure 8 , the front and rear sides of the flip shaft 3325 are provided with a buffer and a limit column facing upward. The buffer is used to buffer the up and down flipping action of the material pouring clamp member 3320 to avoid the impact of the sagger. The limit column can improve the repetitive accuracy of each flipping of the material pouring clamp member 3320.

[0069] In a further embodiment, referring to Figure 8 , the material pouring assembly 3300 also includes a material shaking mechanism 3350. There are two material shaking mechanisms 3350, and the two material shaking mechanisms 3350 are respectively arranged on the left and right sides of the material guide trough 3311. The material shaking mechanism 3350 includes a material shaking rod 3351 and a material shaking drive cylinder 3352. The material shaking rod 3351 includes a hinged end, a driving end and a material shaking end. The driving end and the material shaking end are respectively arranged on both sides of the hinged end. The hinged end is hinged to the material pouring frame 3340. The cylinder body of the material shaking drive cylinder 3352 is hinged to the material pouring frame 3340, and the piston rod of the material shaking drive cylinder 3352 is hinged to the driving end.

[0070] The material shaking driving cylinder 3352 can drive the hinged end to move relative to the material dumping frame 3340, so that the material shaking rod 3351 rotates around the hinged end. When the material shaking rod 3351 rotates around the hinged end, the material shaking end can cut into the space above the material guide groove 3311 from the outside, and knock the sagger in an overturned state on the material dumping clamp member 3320, so that the sintered material in the sagger can be shaken off under the impact.

[0071] In a further embodiment, a vibrator is fixedly connected to the outer side of the guide trough 3311. The vibrator causes the side wall of the guide trough 3311 to vibrate continuously to prevent the sintering material from being blocked in the guide trough 3311. The vibrator can be pneumatic or electric.

[0072] The feeding conveyor line 400 is used to load the powder to be sintered into the sagger. The feeding conveyor line 400 extends in the front-to-back direction. The feeding conveyor line 400 includes: a feeding assembly and a sagger conveyor assembly 410.

[0073] The bowl conveying assembly 410 has a bowl conveying surface extending forward and backward for conveying and supporting the sagger. The bowl conveying surface has a bowl inlet end and a bowl outlet end, which are respectively arranged at the front and rear ends. The bowl conveying assembly 410 can convey the sagger from the bowl inlet end to the bowl outlet end.

[0074] In this embodiment, the bowl conveying assembly 410 includes a conveying drive unit, a transmission mechanism 411 and a bowl-squeezing member 412. The bowl-squeezing member 412 is disc-shaped and has a bowl-squeezing groove. The transmission mechanism 411 includes a transmission chain and two transmission sprockets. The two transmission sprockets are rotatably arranged at the front and rear ends of the bowl conveying assembly 410, and the transmission chain is meshed and wound around the transmission sprockets to form a closed-loop transmission path. A plurality of the bowl-squeezing members 412 are arranged at equal intervals along the transmission chain and are fixedly connected to the transmission chain. The conveying drive unit can be selected as a rotating drive element such as a servo motor, a stepping motor or a pneumatic motor.

[0075] The conveying drive unit can drive the transmission sprocket to rotate, so that the transmission chain can drive the bowl member 412 to move cyclically. The bowl member 412 moves from the bowl inlet end to the bowl outlet end from the front to the back in the upper moving path. In some other embodiments, the bowl body conveying assembly 410 can adopt a heat-resistant conveying line such as a roller conveying line.

[0076] A powder injection station is provided between the bowl inlet end and the bowl outlet end, and the loading assembly has a discharge end connected to the powder injection station. The loading assembly includes a silo 420 and a powder injection mechanism 430. The silo 420 is used to hold powder and is provided with a discharge port 421. The powder injection mechanism 430 has a powder conveying surface extending left and right for conveying powder. The discharge end is provided at one end of the powder conveying surface, and the powder conveying surface also has a material receiving end. The discharge port 421 of the silo 420 is provided above the material receiving end. The discharge end is provided above the powder injection station. The discharge end is provided with a powder injection funnel 431 which is narrow at the top and narrow at the bottom.

[0077] In this embodiment, there are two feeding assemblies, and two powder injection stations are provided on the bowl conveying surface. The number of feeding assemblies can be set according to the cycle time of the powder loading process. When the time required for powder loading is long, multiple feeding assemblies can be set to simultaneously load the saggers on different powder injection stations with the powder to be sintered.

[0078] In a further embodiment, the powder injection station is further provided with a bowl mechanism 440 for lifting the sagger from the bowl member 412. The bowl member 412 is annular, and a position avoidance hole is provided in the middle of the bowl member 412. The bowl mechanism 440 can use a cylinder to lift the sagger upward from the position avoidance hole, so that the sagger can move upward to the discharge end to prevent the powder from falling out of the sagger.

[0079] In this embodiment, the bowl conveying assembly 410 can be a belt conveyor. The bowl conveying assembly 410 preferably has a weighing function, which can monitor the sintering material on it. In some other embodiments, the discharge port 421 of the silo 420 can be provided with a metering valve to control the discharge amount of the powder to be sintered each time, ensuring that the appropriate amount of powder to be sintered can be loaded into the sagger.

[0080] The bowl loading and unloading device 500 is used to carry the saggers so as to load and unload the bowl-carrying kiln vehicle 210. The bowl loading and unloading device 500 includes a bowl loading and unloading robot 510 and a bowl picking and placing gripper 520.

[0081] The bowl loading and unloading robot 510 is used to drive the bowl picking and placing gripper 520 to move. In this embodiment, the bowl loading and unloading robot 510 is a multi-axis robot. A multi-axis robot, also known as a multi-axis manipulator, an industrial manipulator, etc., is an automatically controlled, reprogrammable, multi-degree-of-freedom, multi-purpose manipulator, and is widely used in automated production.

[0082] Reference Fig.11 In this embodiment, the bowl picking and placing gripper 520 comprises: a picking and placing base 521, a clamping claw piece 523 and a bowl picking and placing driving member 524. A limiting portion 522 in the shape of an annular truncated cone is provided in the middle of the picking and placing base 521. The number of the clamping claw piece 523 and the bowl picking and placing driving member 524 is four. The four clamping claw pieces 523 are evenly distributed around the circumference of the limiting portion 522. The clamping claw pieces 523 are all slidably connected to the picking and placing base 521 along the radial direction of the limiting portion 522. The bowl picking and placing driving member 524 is arranged in a one-to-one correspondence with the clamping claw piece 523, and the bowl picking and placing driving member 524 is used to drive the clamping claw piece 523 to move along the radial direction of the limiting portion 522. The bowl picking and placing driving member 524 can be selected as a linear driving member such as a cylinder, an electric push rod, a hydraulic push rod, etc.

[0083] In a further embodiment, the bowl picking and placing gripper 520 further includes a connecting plate 525. The bowl loading and unloading robot 510 is fixedly connected to the connecting plate 525. A guide column and a spring are provided between the picking and placing base 521 and the connecting plate 525. The guide column and the spring are both arranged along the axial direction of the limiting portion 522. The picking and placing base 521 and the connecting plate 525 are elastically connected along the axial direction of the limiting portion 522 through the guide column and the spring.

[0084] When taking and placing the sagger, the limiting part 522 can be against the upper end of the sagger, and the outer side of the sagger is clamped by a plurality of clamping claws 523 moving in the radial direction, so as to realize the clamping and placing of the sagger. The taking and placing base 521 is elastically connected to the connecting plate 525. When taking materials, the limiting part 522 can be elastically pressed against the upper end of the sagger, which is convenient for the debugging of the multi-axis robot and avoids the situation that the sagger is crushed or the limiting part 522 is not in place.

[0085] In particular, if Fig.11 As shown, the shape of the clamping claw piece 523 can be a circular arc groove consistent with the shape of the outer side of the sagger, or it can be a columnar shape. In some other embodiments, the clamping claw piece 523 and the bowl-taking and placing driving member 524 can be other numbers. Fig.12 As shown, the bowl picking and placing gripper 520 is provided with two clamping claws 523. The two clamping claws 523 are respectively arranged at two ends of the opposite sides of the bowl picking and placing gripper 520, and are driven by two bowl picking and placing driving members 524 to clamp toward each other or move away from each other.

[0086] Reference Figures 1 to 12 When the sintering production line of the present invention is used for sintering production:

[0087] First, the sagger containing the powder to be sintered is transported along the sintering section by the sagger-carrying kiln car 210. The sagger is sintered at high temperature in the sintering channel of the kiln 100. The sagger-carrying kiln car 210 carries the sagger that has been sintered and continues to move along the conveying track 220.

[0088] The kiln trolley 210 stops when it moves to the front end of the loading and unloading section, and the sagger is moved from the kiln trolley 210 to the loading station of the receiving device 300 through the loading and unloading device 500 provided on the side of the front end of the loading and unloading section. The emptied kiln trolley 210 moves to the rear end of the loading and unloading section for loading. The sagger is transferred from the kiln trolley 210 to the receiving device 300 through the loading and unloading device 500 on the front side, and the empty sagger after the sintering material is poured out is loaded with the powder to be sintered on the feeding conveyor line 400, and then placed on the kiln trolley 210 through the loading and unloading device 500 on the rear side.

[0089] The kiln car 210 carrying a large number of saggers can carry the saggers, which are collected and loaded with sintered materials and materials to be sintered in turn in the material collecting device 300 and the loading conveyor line 400. Specifically, the lifting drive unit 3142 of the material collecting device 300 drives the lifting member 3141 to lift up, and the lifting member 3141 rises from the lifting avoidance space in the placement slot 3121 to lift the saggers placed in each placement slot 3121.

[0090] It is worth noting that at this time, no sagger is placed on the lifting member 3141 in the loading station. The sagger on the crushing station is lifted up between the two positioning clamps 3242. The sagger on the unloading station is lifted up between the first frame 3322 and the second frame 3323.

[0091] Then, the bowl loading and unloading device 500, the crushing assembly 3200 and the pouring assembly 3300 are operated simultaneously.

[0092] The bowl loading and unloading robot 510 drives the bowl picking and placing gripper 520 to move, and places the sagger to be unloaded obtained from the bowl carrying kiln car 210 on the lifting member 3141 of the loading station. Then the empty sagger on the unloading station is moved to the bowl inlet end of the loading conveyor line 400.

[0093] The positioning drive unit 3241 drives the two positioning clamps 3242 to clamp toward each other, and clamps the sagger in the crushing station in the center. The crushing drive unit 3225 drives the crushing knife 3222 to rotate. The lifting drive component 3230 drives the crushing component 3220 to move downward, so that the crushing knife 3222 extends into the sagger of the crushing station. The rotating crushing knife 3222 scrapes the sintered material in the sagger through the crushing drill 3223 and the scraper 3224, crushes and disperses it. Then, the lifting drive component 3230 drives the crushing component 3220 to retract upward.

[0094] The clamping driving member 3324 drives the first frame 3322 and the second frame 3323 to move toward each other to clamp the sagger. Then the flipping driving member 3330 drives the material unloading clamp member 3320 to flip. After flipping into place, the sintered material in the sagger is poured from the sagger into the material guide trough 3311, and falls into the material receiving box 3312 along the material guide trough 3311. In order to avoid incomplete crushing resulting in the sintered material still adhering to the inner wall of the sagger, the material shaking driving cylinder 3352 can drive the material shaking rod 3351 to swing continuously, and continuously knock the flipped sagger or the material unloading clamp member 3320 through the material shaking end, so that some sintered materials still attached can be shaken off under the impact. After the unloading is completed, the sagger is flipped back to the unloading station, and the material unloading clamp member 3320 is released to allow the empty sagger to fall on the lifting member 3141.

[0095] After the bowl loading and unloading device 500, the crushing assembly 3200 and the material pouring assembly 3300 complete the action, the lifting drive unit 3142 retracts downward to the bottom of the rotating disk 3120, so that the saggers of the loading station, the crushing station and the material pouring station are placed downward on the placement groove 3121. Afterwards, the turntable driving member 3130 drives the rotating disk 3120 to rotate 90 degrees, so that the saggers to be unloaded are transferred to the crushing station, the saggers that have completed crushing are transferred to the material pouring station, and the empty saggers that have completed material pouring are transferred to the unloading station. The lifting member 3140 acts to lift up each sagger, and the bowl loading and unloading device 500, the crushing assembly 3200 and the material pouring assembly 3300 perform the next round of actions again. In this way, the automatic unloading of the saggers is realized.

[0096] The empty sagger that has completed unloading is placed on the inlet end of the feeding conveyor line 400 by the sagger loading and unloading device 500. The sagger is supported and conveyed by the sagger member 412. When the empty sagger moves to the powder injection station, the powder injection mechanism 430 operates to send the divided materials on the powder injection conveying surface out from the discharge end and drop into the sagger. When the sagger filled with powder moves to the discharge end of the feeding conveyor line 400, it is moved to the sagger carrying kiln car 210 at the rear end of the loading and unloading section by the sagger loading and unloading device 500 and neatly stacked.

[0097] In a further embodiment, a visual positioning device 230 is provided above both ends of the loading and unloading section. The visual positioning device 230 can monitor the position and state of multiple saggers on the kiln car 210, so that the loading and unloading robot 510 can drive the picking and placing gripper 520 to move according to the position and number of saggers.

[0098] In some embodiments, the turntable assembly 3100 has only a loading station, a crushing station and a dumping station. The loading station, the crushing station and the dumping station are evenly arranged, and the rotating disk 3120 rotates 120 degrees each time. The bowl loading and unloading device 500 adopts a double-handed claw structure, and the two bowl picking and placing claws 520 complete the loading and unloading of the sagger at the loading station.

[0099] In some embodiments, a sagger loading and unloading device 500 is also provided between the feeding end of the feeding conveyor line 400 and the receiving device 300. The sagger loading and unloading device 500 between the receiving device 300 and the kiln car 210 is used to move the sagger containing the sintering material on the kiln car 210 to the receiving device 300. The sagger loading and unloading device 500 between the feeding end and the receiving device 300 is used to move the empty sagger on the receiving device 300 to the feeding end.
