[0002] The reactor is mainly used for the heat treatment of raw materials and precursor materials of battery electrodes. When used, the raw materials and precursor materials are placed in the reactor and then heat treated in a roller kiln or tunnel kiln. After the heat treatment in the kiln is completed, the kiln is taken out after cooling, the materials in the reactor are taken out, and new raw materials and precursor materials are put in for the next cycle.

[0051] The detection component 7 includes a reciprocating screw 71 fixed at the top center of the driven circular gear 68, and a screw sleeve 72 is threadedly connected to the reciprocating screw 71. The driven circular gear 68 first drives the screw sleeve 72 to perform reciprocating lifting motion through the reciprocating screw 71. The screw sleeve 72 is fixedly connected with a connecting seat 73 on all sides, and the outer side of the connecting seat 73 is fixedly connected with a first high-precision industrial camera 74.

[0052] The shading component 8 includes an electric push rod 81 embedded in the other output shaft of the double-headed motor 61, and the piston rod of the electric push rod 81 is fixedly connected to the driving bevel gear 82, and a bevel gear frame 83 is provided at the bottom of the driving bevel gear 82. The meshing stroke between the driving bevel gear 82 and the bevel gear frame 83 is first adjusted by the electric push rod 81, and the other end of the bevel gear frame 83 is meshed with a driven bevel gear 84, and the top of the driven bevel gear 84 is fixedly connected to a rotating rod 85, and the top of the rotating rod 85 is fixedly connected to a threaded rod 86 that rotates with the top cylinder 3, and is driven by the driven bevel gear 84. The movable bevel gear 84 drives the threaded rod 86 to rotate forward and backward through the rotating rod 85. The threaded rod 86 is threadedly connected with a threaded sleeve 87, and the front of the threaded sleeve 87 is fixedly connected with a support 88. The front of the support 88 is fixedly connected with a light shield 89 used in conjunction with the detection platform 1. The threaded sleeve 87 on the threaded rod 86 drives the light shield 89 through the support 88 to perform light shielding and protection on the reaction vessel on the detection platform 1, so as to prevent external light from interfering with the crack detection work of the reaction vessel in the detection platform 1, thereby further improving the crack detection accuracy of the reaction vessel;

[0053] A first vertical groove 15 slidably matched with the connecting seat 73 is provided on all four sides of the top tube 3, and a second vertical groove 16 slidably matched with the support 88 is provided on the front of the side tube 4, which serves as a sliding limit for the support 88, thereby improving the lifting and lowering stability of the threaded sleeve 87 and the support 88 to prevent the threaded sleeve 87 and the support 88 from shaking or tilting during the lifting and lowering. A sealing groove 17 used in conjunction with the light shield 89 is provided on the top of the testing platform 1, which serves as a sealing and blocking role between the light shield 89 and the testing platform 1, and a limit ring matched with the reaction vessel limit is fixedly connected to the center of the top of the testing platform 1, which is convenient for the center-protected placement of the reaction vessel.

[0054] The positioning assembly 9 includes a connecting rod 91 fixed to the other side of the swing frame 64, and the other end of the connecting rod 91 is fixedly connected to a piston 92 that slides with the cylinder barrel 5. The swing arm 62 first drives the piston 92 on the connecting rod 91 to perform reciprocating work in the cylinder barrel 5. The right end of the cylinder barrel 5 is connected to a three-way pipe 93, and the air intake port of the three-way pipe 93 is connected to a five-way valve 94. The top of the five-way valve 94 is connected to a negative pressure telescopic pipe 95, and the negative pressure suction force generated in the cylinder barrel 5 is sequentially transmitted to the negative pressure telescopic pipe 95 through the three-way pipe 93 and the five-way valve 94, and the top of the negative pressure telescopic pipe 95 is connected to the light shield 89. A matching negative pressure connector 96 is embedded, and the bottom end of the negative pressure connector 96 is connected to a negative pressure suction cup 97 for negative pressure positioning of the reaction vessel. The negative pressure suction force is then applied to the negative pressure suction cup 97 by the negative pressure connector 96, and under the action of the negative pressure suction force, the reaction vessel covered on the periphery of the top tube 3 is negatively positioned to prevent the reaction vessel from shaking during crack detection. The exhaust port of the negative pressure connector 96 is connected to a pressure relief pipe 98, and a pressure relief valve is provided on the pressure relief pipe 98. At the same time, the pressure relief pipe 98 and the pressure relief valve release the pressure on the reaction vessel after the crack detection, which is beneficial to the removal and placement of the reaction vessel after the crack detection.

[0055] like Figure 14-16 As shown, since the reaction vessel and the electrode material reacted therein need to undergo high-temperature heat treatment and low-temperature cold treatment, during the crack detection of the electrode material reaction vessel, the high and low temperature environment cannot be simulated for the reaction vessel in the crack detection state, and the detection is basically carried out at room temperature, resulting in low accuracy of crack detection of the reaction vessel. The positioning component 9 is provided with a temperature control component 10 used in conjunction with the light shield 89, and the temperature control component 10 includes a hot and cold integrated machine 101 fixed at the bottom of the cylinder barrel 5, and one side of the hot and cold integrated machine 101 is unidirectionally connected with a delivery pipe 102 connected and matched with the three-way pipe 93, and the hot and cold integrated machine 101 provides a supply of cold and hot sources, and the delivery pipe 102 is used for delivery and supply;

[0056] The inner end of the five-way valve 94 is connected with an air intake pipe 103, and an air intake valve is arranged on the air intake pipe 103. After the negative pressure positioning of the reaction vessel is completed, the air intake pipe 103 provides air intake to the cylinder 5, and both ends of the five-way valve 94 are connected with exhaust telescopic pipes 104. The top of the exhaust telescopic pipe 104 is connected with a connecting cover 105 fixedly matched with the light shield 89, and a reserved opening 106 connected with the connecting cover 105 is opened on one side of the light shield 89. The cold and hot sources generated by the cold and hot integrated machine 101 are pressurized and discharged by the cylinder 5. The connecting cover 105 on the exhaust telescopic tube 104 is discharged into the sealed light shielding cover 89 through the reserved opening 106, so as to simulate the high and low temperature environment for the reaction vessel in the crack detection in the light shielding cover 89, and improve the crack detection accuracy of the reaction vessel under the high and low temperature environment. A temperature and humidity sensor 107 is embedded on one side of the top of the light shielding cover 89 to monitor the temperature and humidity in the light shielding cover 89 in real time, and a pressure sensor 108 is embedded on the outer end of the three-way pipe 93 to monitor the pressure flowing through the three-way pipe 93 in real time.

[0057] The working principle of a crack detection device for electrode material reaction vessels is as follows: the reaction vessel cover to be detected is first set on the periphery of the top cylinder 3 and is in the limit ring, the electric push rod 81 is first controlled to open and drive the driving bevel gear 82 to move down and clamp to the meshing part of one end of the bevel gear frame 83, and then the double-headed motor 61 is controlled to open and drive the bevel gear frame 83 to rotate through the driving bevel gear 82 that is meshed in place, and the other end of the bevel gear frame 83 drives the driven bevel gear 84 to rotate, and the driven bevel gear 84 drives the threaded rod 86 to rotate forwardly through the rotating rod 85, and the threaded rod 86 drives the threaded The sleeve 87 moves downward accordingly, and the threaded sleeve 87 drives the support 88 to slide downward in the second vertical groove 16. At the same time, the support 88 also drives the light shielding cover 89 to move downward and get stuck in the blocking groove 17 on the detection platform 1, so as to shield the reaction vessel covered by the outer periphery of the top tube 3. At the same time, the light shielding cover 89 also drives the negative pressure suction cup 97 to move downward and fit on the top of the reaction vessel. After the light shielding cover 89 and the detection platform 1 are sealed in place, the double-headed motor 61 is first controlled to pause, and then the electric push rod 81 is controlled to close and drive the driving bevel gear 82 to move upward to disengage the meshing portion of one end of the bevel gear frame 83 to the initial position;

[0058] After the light shield 89 is sealed with the test platform 1, the double-headed motor 61 is controlled to start again and drive the swing arm 62 to rotate. With the first slide rail 11 and the first slide rail block 12 providing sliding support for the swing frame 64, the convex head 63 on the swing arm 62 drives the swing frame 64 to perform horizontal reciprocating motion. The swing frame 64 drives the piston 92 on the connecting rod 91 to perform reciprocating work in the cylinder barrel 5. When the piston 92 is in the return suction state in the cylinder barrel 5, the negative pressure suction force generated by the piston 92 in the cylinder barrel 5 passes through the three-way pipe 93 and the five-way pipe 94 in turn. The valve 94 transmits the pressure to the negative pressure expansion tube 95, and then acts on the negative pressure suction cup 97 through the negative pressure joint 96. Under the action of the negative pressure suction force, the negative pressure suction cup 97 performs negative pressure adsorption and positioning on the reaction vessel in the bonding state, ensuring that the reaction vessel is stable and immovable during the crack detection. If the crack detection of the reaction vessel is completed, the pressure relief valve on the pressure relief pipe 98 can be opened, and the negative pressure suction force in the negative pressure suction cup 97 is released through the pressure relief pipe 98 on the negative pressure joint 96, thereby releasing the negative pressure positioning measure of the negative pressure suction cup 97 on the reaction vessel after the crack detection is completed;

[0059] Next, the second slide rail 13 and the second slide rail block 14 provide sliding support for the single-sided rack frame 65, and the swing frame 64 also drives the single-sided rack frame 65 to reciprocate horizontally. The horizontally reciprocating single-sided rack frame 65 drives the driving circular gear 66 to rotate alternately in the forward and reverse directions. The driving circular gear 66 drives the differential circular gear 67 to rotate alternately in the forward and reverse directions synchronously. The differential circular gear 67 drives the driven circular gear 68 to rotate alternately in the forward and reverse directions. At the same time, the driven circular gear 68 drives the reciprocating screw rod 71 to rotate alternately in the forward and reverse directions. The reciprocating screw rod 71 that rotates alternately in the forward and reverse directions drives the screw rod sleeve 72 to perform reciprocating lifting and lowering movements. The rod sleeve 72 drives the connecting seat 73 to slide reciprocatingly up and down in the first vertical groove 15, and the three groups of connecting seats 73 drive the first high-precision industrial cameras 74 with different angle distributions to perform reciprocating lifting motion along the reaction vessel covered on the outer periphery of the top tube 3, and with the assistance of the first fill light beads 76 lighting the side wall of the reaction vessel, the three groups of the first high-precision industrial cameras 74 with reciprocating lifting motion and different angle distributions perform crack detection operations on the side wall of the reaction vessel, and at the same time, with the assistance of the second fill light beads 77 lighting the top of the reaction vessel, the second high-precision industrial camera 75 performs crack detection operations on the top of the reaction vessel, thereby completing the comprehensive crack detection work of the reaction vessel;

[0060] During the crack detection of the reaction vessel, the hot and cold integrated machine 101 is controlled to start in advance and provide a heat source or a cold source supply, and the heat source or the cold source is supplied to the three-way pipe 93 in one direction by the delivery pipe 102, and after the negative pressure suction cup 97 performs negative pressure adsorption positioning on the reaction vessel in the attached state, the suction valve on the suction pipe 103 is opened to provide a gas source supply to the cylinder barrel 5. When the swing frame 64 drives the piston 92 on the connecting rod 91 to be in the process exhaust state in the cylinder barrel 5, the supplied heat source or cold source is supplied to the two exhaust telescopic pipes 104 through the three-way pipe 93 and the five-way valve 94 in sequence under the action of the boost pressure generated by the piston 92. The pressure sensor 108 monitors the pressure flowing through the three-way pipe 93 in real time, and then the two groups of connecting covers 105 supply the pressure into the sealed light shielding cover 89 through the two groups of reserved openings 106, so as to heat up and cool the inside of the light shielding cover 89 to simulate the high and low temperature environment. The temperature and humidity sensor 107 monitors the temperature and humidity inside the light shielding cover 89 in real time, and then the three groups of first high-precision industrial cameras 74 with the assistance of the first fill light beads 76 and the second high-precision industrial cameras 75 with the assistance of the second fill light beads 77 perform high-precision and comprehensive crack detection on the reaction vessels in the high or low temperature environment.
