By using an intelligent vision processing system, it is possible to accurately locate surface defects and abnormalities on the sides, tops, and bottoms of cylindrical batteries, while ignoring irrelevant changes. The intelligent vision processing system is equipped with a variety of preprocessing functions, which can greatly improve the condition changes caused by the workpiece posture or the external environment, accurately identify defective batteries, improve the detection yield of manufacturers, reduce ineffective detection operations caused by errors, reduce waste, stably identify, and is simple to operate and highly efficient.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figure 1 and Figure 2 , the appearance detection device for cylindrical battery aluminum shells includes an equipment frame 1, and the equipment frame 1 includes a support frame base and a protective frame body. Among them, the protective frame body is located above the support frame base, and openings are provided on both end faces of the protective frame body to facilitate the feeding and discharging of materials. At the same time, it should be particularly noted that the bottom of the support frame base is hollow, and a maintenance door is installed on the side wall of the support frame base. A driving device is installed in the support frame base to facilitate the rotation of the rotary conveyor disk 8; Refer to Figure 2 , a first robotic arm 2 and a second robotic arm 7 are installed on the equipment frame 1. It should be particularly noted that the first robotic arm 2 and the second robotic arm 7 are of the same technology. The mechanical mechanism of the robotic arm is composed of a series of rigid components connected by links. The robotic arm is characterized by having an arm for ensuring mobility, a wrist for providing flexibility, and an end effector for performing the tasks required by the robot. It should be particularly noted that the first robotic arm 2 and the second robotic arm 7 are both prior arts and will not be elaborated here; Refer to Figure 2, the purpose of the first robotic arm 2 is to grab the materials on the conveyor belt on one side of the equipment rack 1 and place the materials on the bearing mechanism 9 to facilitate the movement of the materials. It should be particularly noted that the purpose of the second robotic arm 7 is to take the materials out of the bearing mechanism 9 and then place them on the corresponding conveyor belts according to the quality of the materials. It should be particularly noted that there are two conveyor belts on one side of the equipment rack 1, and these two conveyor belts are used to convey the materials that have been detected. Among them, the qualified materials are placed on the conveyor belt on the production line by the second robotic arm 7, and the unqualified materials are also placed on the conveyor belt of the NG belt line by the second robotic arm 7 to facilitate the staff to classify the qualified and unqualified materials, thus facilitating the work of the staff.

[0020] Refer to Figure 2 , a first detection station 4, a second detection station 5 and a third detection station 6 are installed on the equipment rack 1. It should be particularly noted that a rotary conveyor disk 8 is installed on the equipment rack 1, and the first detection station 4, the second detection station 5 and the third detection station 6 are sequentially arranged in a circular array with the rotary conveyor disk 8 as the center. Therefore, when the rotary conveyor disk 8 rotates by starting the motor and the reduction mechanism, the materials placed on the bearing mechanism 9 can be rotated accordingly, so that the materials can pass through the first detection station 4, the second detection station 5 and the third detection station 6 in sequence, thereby enabling the materials to be fully detected.

[0021] It should be even more noted that the more specific operation steps of the above structure are as follows: The first robotic arm 1 grabs the cylindrical battery aluminum shell from the belt line and puts it into the equipment for appearance detection. After the detection is completed, the second robotic arm 7 classifies and discharges the qualified and unqualified products.

[0022] The first step, the robotic arm grabs the product and puts it into the bearing mechanism 9; The second step, the rotary conveyor disk 8 rotates for bottom surface detection and mouth detection, which is simply the first detection station 4; The third step, the rotary conveyor disk 8 rotates for inner bottom surface detection and bottom surface arc edge detection, which is simply the second detection station 5; The fourth step, the rotary conveyor disk 8 rotates for outer wall detection, which is simply the third detection station 6; The fifth step, the rotary conveyor disk 8 rotates, and through the second robotic arm 7, classification and discharging are carried out. The unqualified products are placed on the NG belt line, and the qualified products flow away on the production line.

[0023] It should be particularly noted that industrial detection cameras and matching systems are provided in both the first detection station 4, the second detection station 5 and the third detection station 6. This is an existing detection technology and will not be elaborated here.

[0024] Refer toFigure 3 and Figure 4 The carrying mechanism 9 includes a placing seat 91. It should be particularly noted that the placing seat 91 is fixed on the rotary conveying disc 8. Multiple corner blocks are installed on the placing seat 91. The multiple corner blocks can be fixed on the rotary conveying disc 8 by screws, so as to achieve the purpose of fixing the placing seat 91. At the same time, a rechargeable lithium battery is installed in the placing seat 91 to supply power to the components on the placing seat 91. Above the placing seat 91, there are two rotatable rotating members 93. The material is placed at the middle position between the two rotating members 93. The distance between the two rotating members 93 is adjusted by a driving member 92. On one side of each of the two rotating members 93, there is a limiting member 94 that can limit the material. A cleaning member 95 that can clean the material is installed on the placing seat 91.

[0025] Refer to Figure 4 and Figure 5 The driving member 92 includes a pulley 921 that can rotate and is arranged in the placing seat 91. It should be particularly noted that a servo motor is fixedly connected to the side wall of the placing seat 91. The driving shaft of the servo motor passes through the side wall of the placing seat 91 and extends to the inside. The pulley 921 is sleeved on the driving shaft of the servo motor. A lead screw 922 is rotatably connected to the inner side wall of the placing seat 91. The lead screw 922 is in transmission connection with the pulley 921. More specifically, a pulley that matches it is sleeved on the side wall of the lead screw 922. The two pulleys are connected by a belt. It should be particularly noted that when the servo motor works, the pulley 921 can be rotated. When the pulley 921 rotates, with the assistance of the belt, the pulley on the lead screw 922 can be rotated, so that the lead screw 922 can be rotated, so that multiple moving rods 927 can move accordingly, so as to adjust the distance between the rotating members 93; Refer to Figure 4 and Figure 5 On the surface of the lead screw 922, there are two opposite threads. Two moving blocks 923 are threadedly connected to the lead screw 922. The two moving blocks 923 are respectively located on the two opposite threads. A limiting rod 924 is fixedly connected to the inner side wall of the placing seat 91. Two movable limiting blocks 925 are sleeved on the limiting rod 924. The two limiting blocks 925 are respectively connected to the two moving blocks 923 through cross bars. In this way, when the lead screw 922 rotates, the two moving blocks 923 can move closer to or away from each other.

[0026] Refer to Figure 4 and Figure 5, vertical columns 926 passing through the side wall of the placement base 91 are fixedly connected to both of the two moving blocks 923. More specifically, strip-shaped openings matching the two vertical columns 926 are provided on the placement base 91. The two vertical columns 926 respectively pass through the strip-shaped openings and extend to the outside of the placement base 91. Two moving rods 927 are fixedly connected to the side walls of the two vertical columns 926. It should be particularly noted that multiple moving rods 927 are all bent, and two sliding grooves are provided on the upper end surface of the placement base 91. Two sliders are slidably connected in each of the two sliding grooves. Multiple bearing seats matching the moving rods 927 are fixedly connected to the multiple sliders. More specifically, one end of each of the multiple moving rods 927 respectively passes through the bearing seat and extends to the outside. It should be particularly noted that the bearing seat can serve the purpose of supporting the moving rod 927. Transmission members 928 are connected to all of the multiple moving rods 927.

[0027] Refer to Figure 5 , Figure 6 and Figure 7 , multiple transmission members 928 include transmission boxes 9281 respectively fixedly connected to one end of multiple moving rods 927.

A rotating shaft 9283 is provided between each pair of transmission boxes 9281. Both ends of the two rotating shafts 9283 respectively pass through the side wall of the transmission box 9281 and are rotatably connected to the side wall of the transmission box 9281. One end of one of the rotating shafts 9283 is connected to the drive shaft of the motor 9282. First helical gears 9284 are coaxially and fixedly connected to the side walls of the two rotating shafts 9283. Second helical gears 9285 meshing with the first helical gears 9284 are rotatably connected to the inner side walls of each pair of transmission boxes 9281. More specifically, rotating rods connected to the second helical gears 9285 are rotatably connected to the inner side walls of each pair of transmission boxes 9281, which can ensure the normal rotation of the second helical gears 9285. At the same time, it should be particularly noted that a pentagonal insertion rod 9286 is rotatably connected to the side wall of one of the pairs of transmission boxes 9281. One end of each of the two pentagonal insertion rods 9286 is respectively connected to two of the rotating rods to ensure that the two pentagonal insertion rods 9286 drive two of the second helical gears 9285 to rotate. A pentagonal insertion cylinder 9287 matching the pentagonal insertion rod 9286 is rotatably connected to the side wall of the other pair of transmission boxes 9281. One end of each of the two pentagonal insertion cylinders 9287 is respectively connected to the other two rotating rods to ensure that the two pentagonal insertion cylinders 9287 are connected to the other two second helical gears 9285. It should be further noted that one end of the pentagonal insertion rod 9286 extends into the pentagonal insertion cylinder 9287.

[0028] Refer to Figure 8 and Figure 9, the rotating member 93 includes a rubber cylinder 931 sleeved on the rotating shaft 9283. A plurality of first through holes 932 are provided on the side wall of the rubber cylinder 931. Rubber seats 933 are fixedly connected to the inner bottoms of the plurality of first through holes 932. Suction cups 934 are fixedly connected to the upper ends of the plurality of rubber seats 933. Anti-slip rings 935 are fixedly connected to the upper end faces of the plurality of suction cups 934. It should be particularly noted that anti-slip patterns are provided on the anti-slip rings 935, and a plurality of rubber bumps 936 are fixedly connected to the upper end faces of the anti-slip rings 935.

[0029] Refer to Figure 8 and Figure 9 , a plurality of second through holes 9311 communicating with the first through holes 932 are provided in the rubber cylinder 931. Springs 9312 are fixedly connected to the inner bottoms of the plurality of second through holes 9311.

Viscous rubber heads 9315 are fixedly connected to the upper ends of the plurality of upright columns 9314.

[0030] Refer to Figure 10 , the limiting member 94 includes first electric telescopic rods 941 respectively fixedly connected to two of the transmission boxes 9281. The output ends of the two first electric telescopic rods 941 are fixedly connected to the same mounting frame 942. A plurality of second electric telescopic rods 943 penetrate through the side wall of the mounting frame 942. Moving seats 944 are fixedly connected to one ends of the plurality of second electric telescopic rods 943. Ball bearings 945 are embedded in the plurality of moving seats 944. An exhaust member 946 connected to an external air source is installed on the mounting frame 942.

[0031] Refer to Figure 10 and Figure 11, the exhaust component 946 includes an exhaust box 9461 fixedly connected to the mounting bracket 942. The exhaust box 9461 is connected to an external air pump through a horizontal pipe. The output end of the exhaust box 9461 is fixedly connected with a plurality of connecting pipes 9462. The output ends of the plurality of connecting pipes 9462 are respectively connected to a plurality of moving seats 944. An annular channel 9463 connected to the plurality of connecting pipes 9462 is provided in each of the plurality of moving seats 944. A plurality of vertical channels 9464 are provided at the output ends of the plurality of annular channels 9463. An air outlet head 9465 is obliquely installed at the output end of each of the plurality of vertical channels 9464. A spiral guide vane 9466 is fixedly connected to the inner side wall of each of the plurality of air outlet heads 9465. It should be particularly noted that when the external air pump works, it can enable external gas to enter the exhaust box 9461, so that the gas can enter the annular channel 9463 and the vertical channel 9464 in the moving seat 944 from the connecting pipe 9462, so that the gas can be discharged from the air outlet head 9465. It should be particularly noted that with the assistance of the spiral guide vane 9466, the gas can be ejected spirally and evenly. At the same time, the diameter of the output end of the air outlet head 9465 is smaller than that of the input end, which can further clean the surface of the ball 945 and also enable the air flow to blow towards the material, further achieving the purpose of cleaning the material.

[0032] Refer to Figure 12 and Figure 13 , the cleaning component 95 includes a fixing plate 951 fixedly connected to the placing seat 91. A bearing plate 952 is inserted on the fixing plate 951. A slot is provided on the fixing plate 951, and an insertion block matching the slot is integrally connected to the bearing plate 952. A pull column 953 is fixedly connected to the upper end of the bearing plate 952. A collection box 954 is fixedly connected to the upper end of the bearing plate 952. A lifting main board 955 is fixedly connected to the inner bottom of the collection box 954. A lifting cleaning board 956 is inserted in the lifting main board 955. At the same time, a screw in contact with the lifting cleaning board 956 is installed on the side wall of the lifting main board 955. The staff can adjust the height of the lifting cleaning board 956 according to the actual situation, so that the lifting cleaning board 956 can abut against the lower surface of the material pipe, but the lifting cleaning board 956 will not affect the rotation of the material pipe, so that the material pipe can be cleaned. It should be particularly noted that the cross section of the top end of the lifting cleaning board 956 is triangular, and the lifting cleaning board 956 is located below the material, so that when the material rotates, the impurities on the surface of the material can be cleaned.

[0033] Refer to Figure 13 and Figure 14, a conduit 9561 connected to the lifting main board 955 is installed on the side wall of the collection box 955. The conduit 9561 is connected to an external air pump. The lifting main board 955 is connected to the lifting cleaning board 956, and a sealing strip is provided at the connection between the lifting main board 955 and the lifting cleaning board 956. The sealing strip is fixed on the inner side wall of the lifting main board 955. A plurality of air blowing ports 9562 are provided on the side wall of the lifting cleaning board 956. The blowing directions of the plurality of air blowing ports 9562 are aligned with the material. Dust-proof nets 9563 are fixedly connected to the inner side walls of the plurality of air blowing ports 9562, thus preventing impurities from accumulating in the air blowing ports 9562. A sponge block 9564 is fixedly connected to the side wall of the lifting cleaning board 956. The upper end of the sponge block 9564 is arc-shaped, so that it can better fit on the material pipeline, further ensuring the cleaning effect of the device.

[0034] Working principle: When the device starts to be used, first, the material is conveyed to a suitable position through the conveyor belt on one side of the equipment frame 1, and then the first robotic arm 2 grabs the material, and then the first robotic arm 2 places the material between two rubber cylinders 931. After that, the feeding station 3 aligns the material. It should be noted that the feeding station 3 includes two groups of cylinders and is located on both sides of the placing seat 91, so that the material can be placed in the middle position between the two rubber cylinders 931; It should be noted that the device can start the servo motor according to the different volumes of the materials. When the servo motor works, the drive shaft of the servo motor can rotate, and further the pulley 921 can rotate. When the pulley 921 rotates, with the assistance of the belt, the lead screw 922 can rotate. When the lead screw 922 rotates, since the moving block 923 is threadedly connected to the lead screw 922 and the moving block 923 is limited by the limiting rod 924 and the limiting block 925, the distance between the two moving rods 927 can be increased or decreased, so that the distance between the two rubber cylinders 931 can be changed, and further the device can place materials of different sizes.

[0035] After that, the rotary conveyor disk 8 is driven by a motor under the equipment frame 1, so that the rotary conveyor disk 8 can rotate accordingly. When the rotary conveyor disk 8 rotates, the placing seat 91 can be rotated to a suitable position, so that the placing seat 91 is in the first detection station 4. The industrial camera in the first detection station 4 can detect the bottom surface and the mouth of the material. After the detection is completed, at this time, the rotary conveyor disk 8 continues to rotate, and then the placing seat 91 will be in the second detection station 5. The second detection station 5 can detect the inner bottom surface and the bottom arc edge of the material. After the detection is completed, the rotary conveyor disk 8 continues to rotate, so that the placing seat 91 is below the third detection station 6. It should be noted that the third detection station 6 can detect the surface of the material; During the above operation process, it should be noted that when the motor 9282 works, one of the rotating shafts 9283 can be rotated. When one of the rotating shafts 9283 rotates, two first bevel gears 9284 can be rotated. Further, two second bevel gears 9285 can be rotated. When the two second bevel gears 9285 rotate, the pentagonal insertion cylinder 9287 can be rotated. It should be particularly noted that the pentagonal insertion rod 9286 is inserted into the pentagonal insertion cylinder 9287. Thus, when the pentagonal insertion cylinder 9287 rotates, the pentagonal insertion rod 9286 can be rotated. Further, the other two second bevel gears 9285 can be rotated. At the same time, the other two first bevel gears 9284 can also be rotated, so that the other rotating shaft 9283 can be rotated, and the rubber cylinder 931 can be rotated; When the rubber cylinder 931 rotates, since the material is placed between the two rubber cylinders 931 and the two rubber cylinders 931 rotate in the same direction, the material can be rotated, so that the third inspection station 6 can inspect the surface of the material. It should be particularly noted that the suction cup 934, the anti-slip ring 935 and the rubber bumps 936 can increase the friction between the rubber cylinder 931 and the material, further ensuring the rotation of the material. It should be particularly noted that when the vertical column 9314 contacts the material, the vertical column 9314 will be subjected to a certain extrusion force, so that the spring 9312 can be contracted, the moving plate 9313 can be moved, and the suction cup 934 can better fit on the surface of the material. The sticky rubber head 9315 can further increase the friction, thus ensuring the rotation of the material.

[0036] During the above operation process, in order to ensure that the material will not shift during rotation, the second electric telescopic rod 943 can work accordingly, so that the ball 945 can fit on the surface of the material. Since the ball 945 is embedded in the moving seat 944, the ball 945 will not affect the rotation of the material. At the same time, it should be particularly noted that the first electric telescopic rod 941 can adjust the height of the second electric telescopic rod 943 according to the volume of the material, so that the device can process different materials; During this process, the external air pump can work accordingly, so that the gas can enter the exhaust box 9461. With the assistance of the connecting pipe 9462, the gas can be ejected from the air outlet head 9465 in the moving seat 944. The setting of the spiral guide vane 9466 can make the gas ejected evenly in a rotating manner. It should be particularly noted that the air outlet direction of the air outlet head 9465 is aligned with the ball 945 and the material, so that the gas can clean the ball 945 and blow the surface of the material at the same time, so as to achieve the cleaning effect.

[0037] The staff can, according to the actual situation, insert the bearing plate 952 into the fixed plate 951, so that the collection box 954 can be positioned below the two rubber cylinders 931. Then, the staff can move the lifting and cleaning plate 956 within the lifting main board 955 according to the size of the material, and then rotate the screw, so that the top end of the lifting and cleaning plate 956 can fit the surface of the material. The cross-section of the lifting and cleaning plate 956 is triangular, so that the impurities on the surface of the material can be effectively cleaned. At this time, the staff can also insert the conduit 9561 into the air pump outlet of the outside world, so that the air blowing port 9562 can blow out gas with the assistance of the outside air pump, so that the material can be cleaned. It should be particularly noted that the air blowing port 9562 is aligned with the surface of the material, and further, it can form a turbulent flow with the gas from the air outlet head 9465, further improving the cleaning effect of the device. The upper end surface of the sponge block 9564 is arc-shaped, so as to ensure the rotation of the material. It should be particularly noted that the sponge block 9564 also plays a role in cleaning. The collection box 954 can collect impurities. The staff can directly pull the pull column 953, so that the bearing plate 952 can be pulled out from the fixed plate 951, facilitating the staff to clean the impurities on the collection box 954.

[0038] After the third inspection station 6 has completed the inspection, the rotary conveyor disk 8 continues to convey the placement seat 91 to a suitable position, and then the second robotic arm 7 operates. At this time, the second robotic arm 7 can place the qualified materials on the conveyor belt on the production line, while the unqualified materials are placed on the conveyor belt on the NG conveyor line, further completing the appearance inspection of the materials.
