Description

Technical Field

[0001] The invention relates to the technical field of lithium ion battery positive electrode material manufacturing equipment, and more specifically to a sagger detection device and selection equipment. Background Art

[0002] Nowadays, lithium battery positive electrode materials generally use high-temperature sintering method for material reaction. Due to the particularity of high-temperature sintering, it is necessary to use a high-temperature resistant sagger carrier for loading and then entering the furnace for high-temperature sintering reaction. During the sintering process of the material, the sagger is used as a recycling device, and it circulates on the outer circulation conveyor line. However, because the sagger frequently experiences sudden cooling and heating changes, the factors affecting the life of the sagger material itself, and the equipment failure factors during the operation in the outer ring line, the sagger is prone to damage. If the sagger is damaged during use, the damaged sagger slag will be brought into the material, causing fluctuations in product performance indicators; if the sagger is seriously damaged, the material will leak when loading, and the damaged sagger will enter the kiln through the outer ring line. During the operation of the roller rod, it is very easy for the sagger to fall into the furnace or get stuck in the roller rod, causing the sintering kiln to fail to operate normally, resulting in greater production losses.

[0003] The mainstream sagger detection method on the market now is mainly based on the subjective consciousness of personnel to make judgments. The subjective judgment standards of personnel with different experiences are inconsistent, which may easily lead to the risk of damaged saggers with different judgment standards continuing to flow into the production line, and the manpower cost is high, time-consuming and labor-intensive. At the same time, some existing detection equipment mainly uses laser rays to judge the damage of saggers, which has a relatively high investment cost, and dust can easily cause pollution to photosensitive equipment, which needs to be cleaned regularly, increasing the corresponding workload. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sagger detection device and a selection device.

[0005] A kind of sagger detection and selection equipment of the present invention adopts the technical scheme as follows: A sagger detection device comprises: a protective cover structure, a fitting mechanism for sealingly fitting with a sagger to be detected is arranged in a detection cavity of the protective cover structure, a medium input cavity is formed between the sagger to be detected and the fitting mechanism, a medium injection mechanism for injecting a medium into the medium input cavity is arranged on the fitting structure, a medium detection mechanism for detecting the injected medium is arranged in the protective cover structure, so as to detect whether the medium injected into the medium input cavity by the medium injection mechanism overflows into the detection cavity through the medium detection mechanism.

[0006] Furthermore, a dust collecting outlet is provided on the protective cover structure, and a valve cover is connected to the dust collecting outlet.

[0007] Furthermore, the medium injection mechanism comprises: a gas source injection nozzle for injecting gas into the medium input cavity; the medium detection mechanism comprises: a gas detector for detecting the injected gas.

[0008] Furthermore, the gas detector is electrically connected to a PLC controller, and the PLC controller is electrically connected to an alarm device.

[0009] Furthermore, the bonding mechanism comprises: a bonding plate, on which a card slot is provided for sealingly engaging with the sagger to be tested.

[0010] A selection device comprises a sagger detection device as described in any one of the above items, wherein a trapezoidal placement opening for outputting damaged saggers is provided at the bottom of the protective cover structure, and a pneumatic valve is connected to the trapezoidal placement opening; a fitting mechanism is connected to the pneumatic valve so that when the pneumatic valve is flipped downward to control the opening of the trapezoidal placement opening, the sagger on the fitting mechanism falls into the trapezoidal placement opening.

[0011] Furthermore, the pneumatic valve is electrically connected to a PLC controller. When the medium detection mechanism detects that the medium injected into the medium input cavity by the medium injection mechanism overflows into the detection cavity, the PLC controller controls the pneumatic valve to open to cause the sagger to fall.

[0012] Furthermore, the selection equipment also includes: an external circulation conveyor line, the external circulation conveyor line includes: a frame passing through the through cavity of the protective cover structure, a plurality of conveying wheel groups for conveying the saggers are rotatably arranged on the frame, a plurality of transmission gear groups on the plurality of conveying wheel groups are connected by chains, and a transmission gear group is connected to a driving motor.

[0013] Furthermore, the two load-bearing wheel groups rotated on the upper surface of the pneumatic valve are arranged side by side with the multiple conveying wheel groups, the two load-bearing wheel groups are located between two adjacent conveying wheel groups, and the fitting mechanism is located between the two load-bearing wheel groups.

[0014] Furthermore, the selection equipment also includes: a lifting control mechanism arranged in the top opening of the bonding mechanism and a clamping and flipping mechanism arranged in the protective cover structure. After the external circulation conveyor line transports the sagger to the top of the bonding mechanism, the lifting control mechanism controls the sagger to rise, so that the clamping and flipping mechanism clamps the two sides of the sagger and controls the flipping of the sagger. After adjusting the sagger opening to face the bonding mechanism, the lifting control mechanism supports and controls the sagger to be sealed and bonded to the bonding mechanism.

[0015] The beneficial effects of the present invention are: In a sagger detection and selection device of the present invention, a closed medium input cavity is formed between the sagger to be detected and the fitting mechanism, and a closed detection cavity is formed in the protective cover structure. In the case of a damaged sagger, the gas injected into the medium input cavity by the medium injection mechanism will overflow into the detection cavity, and the overflowing gas will cause an obvious difference between the original gas concentration in the detection cavity and the actual gas concentration. After detection by the medium detection mechanism, information on whether the sagger is damaged is obtained. The present invention can effectively detect whether the sagger is damaged, and can also clear the material in the sagger. There is no manual participation in the whole operation, which reduces the input of human resources and the workload of the operator. The oxygen source nozzle and the oxygen concentration detector are used in combination. The oxygen concentration detector is relatively sensitive and can accurately determine whether the sagger is damaged. The gas source sprayed by the oxygen source nozzle can clear the material inside the sagger by airflow, avoiding the risk of secondary sintering of the material. In addition, the oxygen source nozzle and the oxygen concentration detector have been popularized in the use scenarios, and the corresponding transformation difficulty and use cost are greatly reduced.

DETAILED DESCRIPTION

[0018] In order to clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] Embodiment 1 See also Figure 1-5 The present invention provides a sagger detection device, comprising: a protective cover structure 100, a fitting mechanism 300 for sealing and fitting with a sagger 200 to be detected is arranged in the detection chamber of the protective cover structure 100, a dust collecting outlet is opened on the protective cover structure 100, and a valve cover is connected to the dust collecting outlet, so as to discharge impurities or gas in the detection chamber after detection, and the dust collecting outlet can be closed or opened by installing or removing the valve cover, and the operation is simple, a medium input chamber is formed between the sagger 200 to be detected and the fitting mechanism 300, and a medium injection port for injecting medium into the medium input chamber is arranged on the fitting structure Mechanism 400, a medium detection mechanism 500 for detecting the medium injected by the medium injection mechanism 400 is provided in the protective cover structure 100, so as to detect whether the medium injected into the medium input cavity by the medium injection mechanism 400 overflows into the detection cavity through the medium detection mechanism 500; during the detection, different types of gases can be injected through the medium injection mechanism 400 according to the actual situation, and the gas concentration sensing equipment corresponding to the injected gas can be used for detection to ensure the accuracy of the detection result; liquid can also be injected, and the corresponding liquid detection equipment can be used for detection, which meets the actual needs.

[0021] The working principle and beneficial effects of the above technical solution are: During the inspection, the sagger 200 to be inspected is sealed and attached to the attaching mechanism 300, so that a relatively closed medium input cavity is formed between the sagger 200 to be inspected and the attaching mechanism 300, and then the medium is injected into the medium input cavity through the medium injection mechanism 400. As the medium is injected, if the sagger 200 is damaged, the injected medium will overflow into the inspection cavity of the protective cover structure 100. At this time, the medium detection mechanism 500 can detect the overflowed medium and determine that the sagger 200 is damaged. On the contrary, if the sagger 200 is not damaged, the injected medium will not overflow into the inspection cavity of the protective cover structure 100.

[0022] During detection, the medium injection mechanism 400 can inject various gases, and the medium detection mechanism 500 is a sensor for detecting various gases, so as to determine whether the sagger 200 is damaged by detecting the concentration change value of the injected gas.

[0023] The medium injection mechanism 400 includes: a gas source injection nozzle for injecting gas into the medium input cavity; the medium detection mechanism includes: a gas detector for detecting the injected gas. The gas detector is electrically connected to the PLC controller, and the PLC controller is electrically connected to the alarm device, so that when the sagger 200 is damaged, an alarm prompt message is issued.

[0024] Compared with the prior art which utilizes the difference in gas pressure to make judgments and utilizes the change in the pressure difference P to perform destructive inspection, which may easily lead to the problem of secondary damage to the sagger, the sagger detection device of the present invention performs detection by injecting gas, does not require high pressure, and will not cause the problem of sagger damage caused by excessive gas pressure. The density of the material in the sagger is relatively light, and the injection of gas can separate it, thereby effectively clearing the material in the sagger.

[0025] For example, in the prior art, there is a method for detecting breakage of a sagger with a patent application number of 201110100254.7. In this patent application, the main detection principle is to use the difference in gas pressure in a confined space for judgment, and to use the change in the pressure difference P for damage inspection, which mainly uses a pressure differential gauge. Not only is it easy to cause secondary damage to the sagger, but the pressure differential measurement is also easily affected by environmental factors (such as temperature, humidity, etc.) and the accuracy of the measuring equipment, which may lead to inaccurate test results. The pressure differential method may not be able to detect tiny cracks or potential weak points. There is even a certain risk in operating under high pressure, which may threaten the safety of the operator and may also cause The problem of equipment damage caused by improper operation can be solved; in the present application, the difference in gas concentration in the confined space is used for judgment, and the oxygen concentration sensing device is used for judgment. When the sagger 200 is damaged, there is a hole in the confined space inside the sagger 200, and the gas overflows, while the detection cavity between the external sagger 200 and the protective cover structure 100 is a fixed confined space. At this time, the gas concentration in the external confined space increases due to the damage of the internal space, which triggers the judgment; compared with the prior art, the present application utilizes the change in gas concentration and uses the oxygen concentration sensing device for judgment. The gas concentration sensing device is more sensitive and is not easy to cause additional secondary damage to the sagger, and the overall inspection sensitivity is higher.

[0026] The protective cover structure 100 includes: a protective cover body and a chassis, the protective cover body is sealed and connected to the chassis, and a closed detection chamber is formed between the protective cover body and the chassis. In this structure, the protective cover body and the chassis are preferably sealed and connected by bolts and nuts so that they can be disassembled for inspection and repair; the bonding mechanism 300 includes: a bonding plate, on which a card slot 301 is provided for sealing and snap-fitting with the sagger 200 to be detected; in the present invention, the gas source injection nozzle can adopt an oxygen gas source nozzle, and correspondingly, the gas detector adopts an oxygen concentration detector, and the oxygen concentration detector is electrically connected to the PLC controller 600, and the PLC controller 600 is electrically connected to the alarm device 700; the medium injection mechanism 400 selects an oxygen gas source nozzle for injecting oxygen into the medium input cavity, and the medium The quality detection mechanism 500 selects an oxygen concentration detector for detecting the oxygen concentration in the detection chamber. When the sagger 200 to be detected is sealed and snap-fitted into the slot 301 on the bonding plate, the oxygen gas source nozzle extends upward into the sagger 200. When the oxygen is ejected from the oxygen gas source nozzle, the gas fills the inner side of the sagger 200. Since the sagger 200 is tightly fitted on the bonding plate, a closed space is formed. When the four walls of the sagger 200 are damaged, oxygen overflows into the detection chamber of the protective cover structure 100. When the oxygen concentration detector detects that the oxygen concentration has risen, it transmits a signal to the PLC controller 600, and the PLC controller 600 controls the alarm device 700 to trigger; conversely, when the four walls of the sagger 200 are not damaged, the oxygen concentration does not change, and the alarm device 700 is not triggered.

[0027] The oxygen gas source nozzle can be connected to the gas source mounting hole of the bonding plate through an injection control mechanism. After the sagger 200 to be inspected is sealed and snap-fitted into the card slot 301 of the bonding plate, the injection control mechanism controls the oxygen gas source nozzle to penetrate into the sagger 200 to be inspected, so as to inject oxygen to different positions of the sagger 200 to be inspected. The injection control mechanism can be a micro multi-axis manipulator, which is electrically connected to the PLC controller 600 and can move under the control of the PLC controller 600.

[0028] Embodiment 2 See also Figure 1-5 A selection device comprises the above-mentioned sagger detection device, wherein the bottom of the protective cover structure 100 is provided with an inverted ladder-shaped placement port 900 for outputting a damaged sagger 200, and the inverted ladder-shaped placement port 900 is cooperatively connected with a pneumatic valve 901; a fitting mechanism 300 is connected to the pneumatic valve 901, so that when the pneumatic valve 901 is flipped downward to control the inverted ladder-shaped placement port 900 to open, the sagger 200 on the fitting mechanism 300 falls into the inverted ladder-shaped placement port 900; the pneumatic valve 901 is electrically connected to a PLC controller 600, and when the medium detection mechanism 500 detects that the medium injected into the medium input cavity by the medium injection mechanism 400 overflows into the detection cavity, the PLC controller 600 controls the pneumatic valve 901 to open to make the sagger 200 fall.

[0029] The working principle and beneficial effects of the above technical solution are as follows: when the sagger detection device detects that the sagger 200 is damaged, a signal is transmitted to the PLC controller 600, and the PLC controller 600 controls the pneumatic valve 901 to open, so that the pneumatic valve 901 flips downward to release the closure of the inverted ladder-shaped placement opening 900, and as the pneumatic valve 901 flips downward, the bonding mechanism 300 can be driven to flip downward, so that the damaged sagger 200 on the bonding mechanism 300 can fall into the inverted ladder-shaped placement opening 900 under the action of its own gravity, and unqualified damaged saggers 200 can be screened out, and qualified saggers 200 can be output for continued use.

[0030] The selection device also includes: an external circulation conveyor line 800, which includes: a frame 801 that passes through the through cavity of the protective cover structure 100, and a plurality of conveying wheel groups 802 for conveying the sagger 200 are rotated on the frame 801, and a plurality of transmission gear groups 803 on the plurality of conveying wheel groups 802 are connected by chains, and a transmission gear group 803 is connected to the driving motor; two load-bearing wheel groups 902 rotated on the upper surface of the pneumatic valve 901 are arranged side by side with the plurality of conveying wheel groups 802, and the two load-bearing wheel groups 902 are located between two adjacent conveying wheel groups 802, and the laminating mechanism 300 is located between the two between the load-bearing wheel groups 902; the selection equipment also includes: a lifting control mechanism 302 arranged in the top opening of the bonding mechanism 300 and a clamping and flipping mechanism 303 arranged in the protective cover structure 100. After the outer circulation conveyor line 800 conveys the sagger 200 to the top of the bonding mechanism 300, the lifting control mechanism 302 controls the sagger 200 to rise, so that the clamping and flipping mechanism 303 clamps both sides of the sagger 200 and controls the flipping of the sagger 200. After adjusting the opening of the sagger 200 to face the bonding mechanism 300, the lifting control mechanism 302 is used to support and control the sagger 200 to be sealed and bonded to the bonding mechanism 300.

[0031] The outer circulation conveyor line 800 is used to convey the sagger 200 to be inspected. After the driving motor is started, the driving motor drives the transmission gear set 803 connected thereto to rotate, thereby driving multiple transmission gear sets 803 to rotate through the cooperation of the transmission gear set 803 and the chain, and then controlling the rotation of multiple conveying wheel sets 802, so as to move the sagger 200 through multiple conveying wheel sets 802, and control the displacement of the sagger 200. When the sagger 200 moves onto the two load-bearing wheel sets 902, the sagger 200 and the bonding mechanism 300 are also relatively matched, and the upper surface of the bonding mechanism 300 is tangent to the upper part of the load-bearing wheel set 902, so as to ensure that the sagger 200 can be sealed and bonded with the bonding mechanism 300. The bonding mechanism 300 is preferably provided with a bonding plate that is sealed and engaged with the card groove 301 of the sagger 200 to be inspected. During transportation, in order to To prevent the materials in the sagger 200 from being scattered in the outer circulation conveyor line 800 or in the protective cover structure 100, the opening of the sagger 200 is controlled to move upward. When the sagger 200 moves to the top of the bonding board through the outer circulation conveyor line 800, it is necessary to control the opening of the sagger 200 to be set toward the bonding board. At this time, the lifting control mechanism 302 arranged in the top opening of the bonding mechanism 300 is started, and the lifting control mechanism 302 lifts the sagger 200 to a preset height, and then clamps the two sides of the sagger 200 through the clamping and flipping mechanism 303 and controls the sagger 200 to flip, and adjusts the opening of the sagger 200 to face the bonding mechanism 300. Finally, the lifting control mechanism 302 supports and controls the sagger 200 to be sealed and bonded to the bonding mechanism 300, so that the opening of the sagger 200 is sealed and matched with the slot 301 of the bonding board.

[0032] The lifting control mechanism 302 can be a lifting cylinder and a support frame installed on the lifting cylinder. The lifting cylinder is installed in the top opening of the bonding plate. The lifting cylinder can control the support frame to extend or retract into the top opening of the bonding plate. After the lifting cylinder is started, it carries and controls the lifting of the sagger 200 through the support frame; the clamping and flipping mechanism 303 may include two rotating cylinders relatively arranged on the support frame, the inner ends of the two rotating cylinders are connected one by one with the two horizontal cylinders, and the inner ends of the two horizontal cylinders are provided with clamping plates to control the two clamping plates to position and clamp the sagger 200 to be inspected when the horizontal cylinders are extended. When it is necessary to control the flipping of the sagger 200 to be inspected, the two rotating cylinders control the flipping of the two horizontal cylinders and the clamping plates inside them, thereby realizing the flipping control of the sagger 200.

[0033] When the sagger detection device detects that the sagger 200 is damaged, the PLC controller 600 controls the pneumatic valve 901 to open. At this time, the damaged sagger 200 can fall into the inverted ladder-shaped placement port 900 and be discharged through the inverted ladder-shaped placement port 900, thereby realizing the function of selecting the damaged sagger 200. When there is no damage, the pneumatic valve 901 is always in a closed state. The sagger 200 after detection first rises under the control of the lifting control mechanism 302, and after being flipped 180° by two rotating cylinders, it returns to normal operation again, and is sent back to the external circulation conveyor line 800 under the control of the lifting control mechanism 302 and the clamping and flipping mechanism 303, and is output with the normal movement of the external circulation conveyor line 800 to complete the process closed loop.
