[0018] It should be noted that the embodiments and features of the present application can be combined if there is no conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.
[0019] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all.

[0021] It should be understood that when an element (such as a layer, film, region, or substrate) is described as "on" another element, it can be directly on the other element, or there can be an intermediate element. Also, in the present application, when an element is described as "connected" to another element, it can be "directly connected" to the other element, or "connected" to the other element through a third element.
[0022] Embodiment one As Figures 1-4 The present embodiment provides a saggar loading control method, comprising the following steps: S1. Controlling the weighing bin 5 to output a set quality of material, the set quality being determined based on the capacity of the saggar to be loaded; wherein the quality of the material output by the weighing bin 5 can be obtained by weighing before and after the output of the material and subtracting the results, and the output material can be controlled to meet the set quality requirement by further controlling the time, rate, etc. of the output material, i.e. the output material is within a certain interval range of the set quality; S2. Controlling the saggar conveying device to convey the saggar to be loaded to the loading displacement chamber 15; the saggar to be loaded needs to enter the loading displacement chamber 15 to be filled with the material output by the weighing bin 5; S3. Control the loading mechanism 9 to load the material output from the weighing silo 5 into the loading replacement chamber 15 to be loaded into the sagger, wherein the loading mechanism 9 is connected to the outlet of the weighing silo 5; S4. Control the sagger conveying device to send the loaded sagger in the charging replacement chamber 15 out of the charging replacement chamber 15. The sagger loading is completed and the next production process is continued.
[0023] like Figure 2 、 3 In one embodiment shown, in step S2, the saggers to be loaded need to enter the incoming sagger exchange chamber 14 during transportation to transition to a changed production environment. Specifically, the sagger conveying device is controlled to convey the saggers to be loaded into the incoming sagger exchange chamber 14 and change the production environment, and then the saggers enter the charging exchange chamber 15, which has already changed the production environment. During the process of conveying the saggers to be loaded, the charging exchange chamber 15 can be controlled to change the production environment in advance to facilitate coordination with the incoming sagger exchange chamber 14. In other words, in step S2, the sagger conveying device is controlled to convey the saggers to be loaded to the incoming sagger exchange chamber 14 and change the production environment within the incoming sagger exchange chamber 14, and the sagger conveying device is controlled to convey the saggers to be loaded into the charging exchange chamber 15, which has already changed the production environment, wherein the charging exchange chamber 15 changes the production environment in advance. Since the charging exchange chamber 15 changes the production environment in advance to dock with the incoming sagger exchange chamber 14 to receive the saggers to be loaded, the docking time and the time for converting the production environment can be reduced, thereby improving the efficiency of sagger conveying and supply, and facilitating rapid loading. The production environment is preferably in a nitrogen-filled state, in order to isolate the material from the air and protect the material from oxidation and deterioration.
[0024] like Figure 2 、 3In one embodiment shown, in step S2, the loading displacement chamber 15 is controlled to be closed and the production environment is switched, after the to-be-loaded batch-off pot enters the batch-off pot displacement chamber 14, the batch-off pot displacement chamber 14 is controlled to be closed and the production environment is switched to be consistent with the loading displacement chamber 15, the loading displacement chamber 15 is controlled to be communicated with the batch-off pot displacement chamber 14, and the batch-off pot conveying device is controlled to convey the to-be-loaded batch-off pot from the batch-off pot displacement chamber 14 into the loading displacement chamber 15, and the loading displacement chamber 15 is controlled to be closed to isolate the batch-off pot displacement chamber 14. Specifically, the sealing doors at both ends of the loading displacement chamber 15 are controlled to be closed and the production environment is switched, after the to-be-loaded batch-off pot enters the batch-off pot displacement chamber 14, the sealing doors at both ends of the batch-off pot displacement chamber 14 are controlled to be closed and the production environment is switched to be consistent with the loading displacement chamber 15, the sealing door between the loading displacement chamber 15 and the batch-off pot displacement chamber 14 is controlled to be opened, and the batch-off pot conveying device is controlled to convey the to-be-loaded batch-off pot from the batch-off pot displacement chamber 14 into the loading displacement chamber 15, and the sealing door at the entrance of the loading displacement chamber 15 is controlled to be closed. In the above technical solution, the opening and closing of the sealing door are controlled to control the opening and closing of the batch-off pot displacement chamber 14 and the loading displacement chamber 15, so that the batch-off pot displacement chamber 14 and the loading displacement chamber 15 can be connected or separated by cooperating with each other; when they are connected, the to-be-loaded batch-off pot is conveyed; when they are separated, the loading displacement chamber 15 switches the production environment, the batch-off pot displacement chamber 14 receives the next to-be-loaded batch-off pot and switches the production environment again after being closed. The butt joint of the batch-off pot displacement chamber 14 and the loading displacement chamber 15 can make the to-be-loaded batch-off pot match the production environment during the conversion of the production environment in advance during the conveying of the to-be-loaded batch-off pot, reduce the butt joint matching time of the two, and also make the to-be-loaded batch-off pot continuously in a certain production environment to protect the material.
[0025] As Figure 4In an embodiment shown, the sagger conveying device comprises a first conveying mechanism 17 and a second conveying mechanism 18. The first conveying mechanism 17 is arranged at the bottom of the sagger inlet displacement chamber 14; the second conveying mechanism 18 is arranged at the bottom of the sagger loading displacement chamber 15 which is arranged on the frame 10 and is in abutment with the sagger inlet displacement chamber 14. The sagger loading displacement chamber 15 is used to convert the production environment into one suitable for the sagger inlet displacement chamber 14 before the sagger is conveyed into the sagger inlet displacement chamber 14. The sagger inlet displacement chamber 14 and the sagger loading displacement chamber 15 are both provided with a suction pipe 16 and a filling pipe. The filling pipe is used to supplement nitrogen, and the suction pipe 16 is used to discharge the air displaced when the nitrogen is filled. The first conveying mechanism 17 and the second conveying mechanism 18 are both roller conveyors which are mature products and can be purchased. The sagger inlet displacement chamber 14 and the sagger loading displacement chamber 15 are provided with a sealing door therebetween. The sealing door is used to close the sagger inlet displacement chamber 14 and / or the sagger loading displacement chamber 15. The sealing door can connect the sagger inlet displacement chamber 14 and the sagger loading displacement chamber 15 together or separate them into independent production environment units. The specific implementation is as follows: the sagger loading displacement chamber 15 has the function of environment conversion. Before the sagger is conveyed into the sagger inlet displacement chamber 14, the sagger loading displacement chamber 15 is adjusted to the first production environment (the parameters of the production environment such as temperature, pressure, atmosphere, etc.) consistent with or substantially consistent with the sagger loading displacement chamber 15. Then, the sagger is conveyed into the sagger loading displacement chamber 15 by the first conveying mechanism 17. Subsequently, the sealing door separates the sagger inlet displacement chamber 14 from the sagger loading displacement chamber 15. The sagger loading displacement chamber 15 performs production work in the first production environment, and the sagger inlet displacement chamber 14 is converted into the second production environment and receives the next sagger. The above process is repeated to ensure the process continuity of the sagger during the conveying process across the functional area (i.e., the sagger inlet displacement chamber 14 is used for sagger inlet, and the sagger loading displacement chamber 15 is used for sagger loading). For example, the first production environment is nitrogen filling, and the second production environment is air consistent with or connected to the sagger conveying mechanism.
[0026] As shown in Figure 2 , 3 In an embodiment shown, in step S2, the sealing door closing the outlet of the sagger inlet displacement chamber 14 is controlled to open, the sealing door closing the inlet of the sagger inlet displacement chamber 14 is controlled to open, and the sealing door closing the inlet of the sagger inlet displacement chamber 14 is controlled to close after the next sagger to be loaded enters the sagger inlet displacement chamber 14, and the production environment is converted. The sealing door closing the outlet of the sagger loading displacement chamber 15 is controlled to open, and the sealing door closing the outlet of the sagger loading displacement chamber 15 is controlled to close after the sagger conveying device sends the sagger loaded out of the sagger loading displacement chamber 15, and the sagger loading displacement chamber 15 is controlled to convert the production environment to receive the next sagger to be loaded. Preferably, the sagger inlet displacement chamber 14 and the sagger loading displacement chamber 15 share one sealing door. Opening the sealing door can connect the two, and closing the sealing door can isolate the two.
[0027] As shown in Figures 2-4The shown cooperation of the sealing door has the following example. The sealing door is arranged between the pot-receiving replacement chamber 14 and the charging replacement chamber 15, and is used to close the pot-receiving replacement chamber 14 and / or the charging replacement chamber 15; a transition chamber is arranged at the joint of the pot-receiving replacement chamber 14 and the charging replacement chamber 15; the first end of the transition chamber is connected to the pot-receiving replacement chamber 14, and the second end is connected to the charging replacement chamber 15; wherein the door plate of the sealing door between the pot-receiving replacement chamber 14 and the charging replacement chamber 15 is arranged in the transition chamber. Preferably, the sealing door comprises a first sealing door 24, a second sealing door 22 and a third sealing door 23. The first sealing door 24 is arranged at the inlet end of the pot-receiving replacement chamber 14, and is used to isolate the external environment. The second sealing door 22 is arranged between the pot-receiving replacement chamber 14 and the charging replacement chamber 15, and realizes dynamic isolation of the two functional areas of the pot-receiving replacement chamber 14 and the charging replacement chamber 15; wherein the door plate of the second sealing door 22 is arranged in the transition chamber, the second linear actuator is arranged outside the transition chamber and at the top of the transition chamber, a part of the push rod passes through the top of the transition chamber and is connected to the action rod at the top outside the transition chamber, and a mechanical seal is arranged at the joint of the push rod and the top of the transition chamber. The second linear actuator drives the push rod to drive the door plate of the second sealing door 22 to rise and fall to complete the opening and closing action (communication or isolation of the pot-receiving replacement chamber 14 and the charging replacement chamber 15). The pot-receiving replacement chamber 14 and the charging replacement chamber 15 can be directly connected through the second sealing door 22 to realize the sealing function, and the second sealing door 22 can be regarded as a transition chamber. The third sealing door 23 is arranged at the outlet end of the charging replacement chamber 15, and guarantees the output of the charged pot. The pot supply device can separate the pot-receiving replacement chamber 14 and the charging replacement chamber 15 into independent production environment units through the cooperation of the first sealing door 24 and the second sealing door 22, adjust the production environment of the pot-receiving replacement chamber 14 to be consistent with that of the charging replacement chamber 15, then connect the two chambers and transport the pot into the charging replacement chamber 15, and then separate the pot-receiving replacement chamber 14 and the charging replacement chamber 15 into independent production environment units through the second sealing door 22 again, so that the pot-receiving replacement chamber 14 and the charging replacement chamber 15 perform different processes respectively.For example, the second sealing door 22 and the third sealing door 23 are closed, and the nitrogen-filling environment is provided in the charging displacement chamber 15; the saggar enters the saggar displacement chamber 14 from the first sealing door 24, the first sealing door 24 is closed, and the nitrogen-filling environment is provided in the saggar displacement chamber 14 to match the nitrogen-filling environment in the charging displacement chamber 15; the second sealing door 22 is opened, and the saggar is transported into the charging displacement chamber 15; the second sealing door 22 is closed, and the saggar performs the charging process in the charging displacement chamber 15; the first sealing door 24 is opened, and the next saggar is sent into the saggar displacement chamber 14; the first sealing door 24 is closed and filled with nitrogen; while the next saggar is sent into the saggar displacement chamber 14, the charging displacement chamber 15 is filled with nitrogen after the charging process is completed and the saggar is output from the third sealing door 23; the third sealing door 23 is closed and filled with nitrogen; then, the second sealing door 22 is opened, and the next saggar enters the charging displacement chamber 15 from the saggar displacement chamber 14, so that the continuous operation of the saggar input, the nitrogen-filling environment conversion, the saggar charging, and the saggar output is completed. Of course, the third sealing door 23 described above can be cancelled or kept closed, and the saggar returns to the saggar displacement chamber 14 after being charged in the charging displacement chamber 15 and continues to be output; then, the next saggar is sent into the saggar displacement chamber 14; wherein, the charging displacement chamber 15 is in the nitrogen-filling state for a long time, and the saggar displacement chamber 14 also needs to be kept in the nitrogen-filling state until the saggar displacement chamber 14 receives the saggar after the saggar is transported out of the saggar displacement chamber 14, and then the nitrogen-filling environment is converted to receive the next saggar.
[0028] As shown in an embodiment in Figure 2 , 3 , the saggar charging control method further includes the following steps: S5, controlling the weighing buffer bin 2 to supply material to the weighing bin 5 for continuous output of material from the weighing bin 5, wherein the weighing buffer bin 2 is arranged above the weighing bin 5 and is used to buffer material. Preferably, the weighing buffer bin 2 is controlled to input material to the weighing bin 5 for replenishment according to the rate of output of material from the weighing bin 5; wherein when the weight of the weighing bin approaches the lower limit, the rate of replenishment of the weighing bin by the weighing buffer bin is increased; when the weight of the weighing bin approaches the upper limit, the rate of replenishment of the weighing bin by the weighing buffer bin is reduced or the replenishment is suspended. In this way, the material in the weighing bin 5 is within a certain mass range and can be continuously output. It can be understood that the weighing buffer bin 2 replenishes the weighing bin 5 in the gap of output of material from the weighing bin 5, because if the weighing bin 5 is replenished with material while outputting material, it will affect the monitoring of the weight of the material output from the weighing bin 5. The monitoring of the weight and the weighing of the weighing bin 5 before and after the output of material in step S1 and the difference between the results can obtain the weight of the material output from the weighing bin 5, which is achieved by the weighing sensor 6 arranged outside the weighing bin 5. The weighing sensor 6 can be arranged in multiple pieces and support the weighing bin 5 on the ring plate 7, and the ring plate 7 is fixed to the rack 10. The weighing sensor 6 is used to weigh the weighing bin 5 and the material in it, wherein the weight of the material is obtained by subtracting the weight of the weighing bin 5 during weighing. The weighing method of multiple weighing sensors 6 is called multi-point weighing. The signals transmitted by each weighing sensor 6 can be processed to calculate the accurate weight. This technology belongs to the prior art, and such equipment can be directly purchased, and attention should be paid to the matching of the range and the weight.
[0029] As Figure 2 , 3In the embodiment shown, in step S5, the rate at which the second lateral conveyor 3 outputs the material to the weighing hopper 5 is controlled, wherein the second lateral conveyor 3 is arranged between the inlet of the weighing hopper 5 and the outlet of the weighing buffer hopper 2. The connection between the second lateral conveyor 3 and the weighing hopper 5 is a soft connection, such as the second soft connection mechanism 4, to avoid affecting the weighing of the weighing hopper 5. Preferably, the material output by the second lateral conveyor 3 is material of a set mass, that is, the weighing hopper 5 outputs how much material, and the weighing buffer hopper 2 supplements how much material to the weighing hopper 5 to ensure that the capacity of the material in the weighing hopper 5 is constant. Further, the rate at which the second lateral conveyor 3 outputs the material is consistent with the rate at which the weighing hopper 5 outputs the material, that is, the rate at which the second lateral conveyor 3 outputs the material is consistent with the rate at which the first lateral conveyor 11 outputs the material, which can avoid the second lateral conveyor 3 impacting the weighing hopper 5 when supplementing material to the weighing hopper 5, thereby affecting the accuracy of the weighing of the weighing hopper 5. The rate at which the second lateral conveyor 3 outputs the material can also be controlled to be 1.05-1.1 times the rate at which the first lateral conveyor 11 outputs the material, and the rate at which the second lateral conveyor 3 outputs the material is 150-300 kg / h, which is a redundant design that can ensure sufficient material supply to the pot. For example, Figure 2 、 3 In the embodiment shown, the second lateral conveyor 3 is a screw conveyor, in particular a tubular screw conveyor. The tubular screw conveyor adopts a closed tubular shell, and a rotating spiral blade is arranged inside. The material moves in the tube by being pushed by the rotation of the spiral blade. Whether the material is powdery, granular, or small blocky, the tubular screw conveyor can achieve efficient conveying. The tubular screw conveyor adopts a fully closed structure, so that the material cannot leak to the outside environment during conveying, and external impurities cannot enter the inside of the conveyor. This sealing design not only reduces material waste and environmental pollution, but also ensures the purity of the conveyed material.
[0030] In the embodiment shown, Figure 2 、 3 In step S5, the rate at which the first lateral conveyor 11 outputs the material to the charging mechanism 9 is controlled, and the material output by the first lateral conveyor 11 is material of a set mass. The rate at which the first lateral conveyor 11 outputs the material to the charging mechanism 9 is Q m , Q m =η•ρV / T wherein η is a safety redundancy factor, which is usually 1.2-1.3; ρ is the density of the material in the pot, in kg / m 3 ; V is the volume of a single pot, in m 3 ; Q mThe feeding rate of the buffer bin to the weighing bin, in kg / h; T is the duration of the potting rhythm, i.e. the duration of potting each pot, in h; The first transverse conveyor 11 is arranged between the discharge port of the weighing bin 5 and the charging mechanism 9, and the first transverse conveyor 11 and the weighing bin 5 are connected by a soft connection, such as a first soft connection mechanism 12, to avoid affecting the weighing of the weighing bin 5. The first soft connection mechanism 12 and the second soft connection mechanism 4 can be flexible pipes, such as corrugated pipes. That is, the first transverse conveyor 11 can control the charging efficiency of the charging mechanism 9, and appropriate control of the material output rate can effectively prevent material scattering, overcharging or undercharging during charging of the charging mechanism 9, maintain the constant quality of the charging, and be conducive to the control of the finished product quality during sintering of the material.
[0031] Further, the control of the output material rate is based on the rhythm requirement and the precision requirement, and preferably: the front section is fast, and the rear section is slow and accurate, to ensure the charging rhythm while considering the charging precision, and the charging can be controlled by rate, time or charging amount in three or four sections. There is an example of controlling the output material rate, the discharging rate of the first transverse conveyor 11 can be executed in sections, such as slow section, low section, medium section and high section, and the discharging rate of the first transverse conveyor 11 is controlled at 200-600 r / min; the weight of the material during discharging corresponds to the speed section, which is 6-60 kg, such as 60 kg in the low section, 55 kg in the medium section and 6 kg in the high section. Correspondingly, when the charging mechanism 9 is potting, the discharging rate of the first transverse conveyor 11 can be executed in sections, such as low section, medium section and high section, and the rate of the first transverse conveyor 11 is controlled at 400-600 r / min; during potting, the discharging weight of the material controlled by the first transverse conveyor 11 corresponds to the speed section, which is 10-45 kg, such as 10 kg in the low section and 45 kg in the high section.
[0032] In one embodiment, the selection / design of the first transverse conveyor 11 refers to the second transverse conveyor 3.
[0033] For example, Figure 2 , 3In one embodiment shown, the opening and closing degree of the valve 27 arranged at the discharge port of the weighing hopper 5 and the opening and closing degree of the valve 27 arranged at the discharge port of the weighing buffer hopper 2 are controlled in step S5 to control the on-off of the material output and the rate of the material output. In one example, the valve 27 of the weighing hopper 5 is arranged directly at the discharge port of the weighing hopper 5, and the valve 27 of the weighing buffer hopper 2 is arranged at the discharge port of the second transverse conveyor 3. The reason for such arrangement is that the material output of the weighing hopper 5 needs to be strictly controlled in quality, that is, the set quality of the material output of the weighing hopper 5 needs to be strictly controlled, because the set quality is determined based on the capacity of the to-be-loaded saggar, and it is necessary to ensure that the loading capacity of the saggar is basically constant each time. Therefore, the set quality of the material received by the first transverse conveyor 11 should be delivered to the loading mechanism 9 for loading into the saggar. The requirement for the quality of the material supplemented by the weighing buffer hopper 2 to the weighing hopper 5 through the second transverse conveyor 3 is not high, for example, the material in the weighing hopper 5 only needs to be maintained to a certain extent. Therefore, the valve 27 can be arranged at the discharge port of the second transverse conveyor 3 or the discharge port of the weighing buffer hopper 2, and there is no obvious adverse effect on the supplemented material.

[0036] 2. Control of saggar conveying to improve saggar conveying and loading efficiency By controlling the docking of the saggar replacement chamber 14 and the loading replacement chamber 15 and converting the production environment in advance, the docking time and the production environment conversion time of the saggar during conveying and loading can be reduced, thereby improving the efficiency of saggar conveying and loading. The docking of the saggar replacement chamber 14 and the loading replacement chamber 15 is controlled to enable the to-be-loaded saggar to convert the production environment in advance during conveying, match the production environment during loading, and separate and communicate the saggar replacement chamber 14 and the loading replacement chamber 15, thereby reducing the time for converting the production environment and further improving the production efficiency.
[0037] 3. Flexible adjustment of the production environment By controlling multiple sealing doors to flexibly adjust the conversion and matching of the production environment of the magazine replacement chamber 14 and the charging replacement chamber 15, the rapid conversion and isolation between different production environments are realized, and the flexibility and adaptability of production are improved.
[0038] 4. Efficient use of equipment to control continuous production By controlling the replenishment of the weighing buffer bin 2 to the weighing bin 5, it can ensure the continuous output of the weighing bin 5, and realize the continuous production. By controlling the replenishment rate of the second transverse conveyor 3 to the weighing bin 5 to be consistent with the output rate of the weighing bin 5, it can avoid impacting the weighing bin 5 and affecting the accuracy of the weighing, while improving the utilization rate of the equipment.
[0039] 5. Accurate control of charging efficiency By controlling the output rate of the first transverse conveyor 11 to the charging mechanism 9, it can effectively avoid the situation of material scattering, overcharging / undercharging during charging of the charging mechanism 9, and maintain the constant quality of the charging.
[0040] 6. Protecting materials from oxidation and deterioration By controlling the production environment to be converted to a nitrogen-filled state, the material can be isolated from air to protect the material from oxidation and deterioration, and the stability of the material quality is improved.
[0041] 7. Reduce material waste and environmental pollution Using fully enclosed conveying equipment such as tubular screw conveyor, it can reduce the leakage and waste of materials during conveying, prevent external impurities from entering the inside of the conveyor, ensure the purity of the conveyed materials, and reduce environmental pollution.
