Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery shell sorting device. Background Art

[0002] In the battery manufacturing industry, the battery case, a crucial protective structure for the cell, has a crucial impact on the battery's overall performance, safety, and production efficiency. However, a common practice in current battery production lines is to use two separate devices to measure the outer dimensions and wall thickness, respectively.

[0003] Specifically, one part of the sorting equipment is to accurately measure the external dimensions of the battery shell, such as length, width, height and dimensional deviations of key parts, and then sort the battery shells with qualified and unqualified external dimensions based on the measurement results.

[0004] On the other hand, another part of the sorting equipment is to measure the wall thickness of the battery shell and then sort the battery shells with qualified wall thickness and unqualified wall thickness according to the measurement results.

[0005] The above-mentioned separate detection and sorting method causes two sorting devices to occupy production space separately, and multiple conveying structures need to be set up accordingly, which increases the floor space of the assembly line. In addition, the operation and maintenance of the two sorting devices require more manpower and time investment, increasing production costs and complexity. Utility Model Content

[0006] In order to overcome at least one of the defects described in the above-mentioned prior art, the present invention provides a battery shell sorting device, which can solve the problem that two sorting devices are required to measure the battery shell during the measurement process, thereby increasing the cost and complexity of battery production.

[0007] The technical solution adopted by the present invention to solve the problem is:

[0008] A battery shell sorting device, comprising:

[0009] a conveying structure, wherein the conveying structure conveys the battery casing along a first direction;

[0010] a first dimension measuring assembly and a second dimension measuring assembly provided at both ends of the conveying structure along the first direction, the first dimension measuring assembly and the second dimension measuring assembly being used to measure the outer dimensions of the battery housing;

[0011] a thickness measuring assembly provided on one side of the conveying structure;

[0012] a material distribution assembly provided on one side of the conveying structure;

[0013] The first size measuring component and the second size measuring component are arranged opposite to each other along the first direction.

[0014] By adopting the above solution, the first dimension measurement component and the second dimension measurement component are arranged relative to each other along the first direction, which can accurately measure the external dimensions of the battery casing on the conveyor structure, ensuring the accuracy of the battery casing external dimension measurement data. The thickness measurement component is arranged on one side of the conveyor structure, which can detect the wall thickness of the battery casing during conveyance, thereby ensuring the accuracy of the battery casing thickness measurement data.

[0015] By arranging the first dimension measuring component, the second dimension measuring component, the thickness measuring component and the material sorting component around the conveying structure, the material sorting component sorts qualified and unqualified battery shells, thereby completing the external dimension measurement, wall thickness measurement and sorting of the battery shells on the basis of a single conveying structure, thereby improving the integration of battery production equipment, reducing the floor space of the assembly line, and further reducing the manpower and time required for operation and maintenance, thereby reducing the production cost and complexity of the battery shells.

[0016] Furthermore, it includes a controller, the first size measuring component includes a detection signal sending module, the second size measuring component includes a detection signal receiving module for receiving detection information sent by the detection signal sending module, the detection signal sending module and the detection signal receiving module are both electrically connected to the controller, the battery shell is located between the detection signal sending module and the detection signal receiving module, and the battery shell blocks part of the detection information from being transmitted to the detection signal receiving module, so that the detection information received by the detection signal receiving module is compared with the standard size of the battery shell preset in the controller.

[0017] By adopting the above solution, a controller is provided to facilitate integration of the collected values ​​of the first size measurement component and the second size measurement component and comparison with a battery shell of a standard size.

[0018] Furthermore, the detection signal emitting module is provided with N laser emitters, the N laser emitters are arranged in a matrix, and all the laser emitters emit lasers along the first direction; the detection signal receiving module is provided with N photoresistors, the N photoresistors are arranged in a matrix, and the N photoresistors correspond one-to-one to the N laser emitters, and each photoresistor can receive the laser emitted by the corresponding laser emitter, and the N laser emitters and the N photoresistors are electrically connected to the controller.

[0019] By adopting the above solution, by setting N laser emitters and N photosensitive resistors, and the N laser emitters and N photosensitive resistors are arranged in one-to-one correspondence. When the battery case is placed on the conveying structure, some laser emitters will be blocked by the battery case, resulting in the photosensitive resistors corresponding to these laser emitters being unable to receive the laser, and further resulting in a higher resistance value of these photosensitive resistors. Thus, the size of the upper end face of the battery case in the first direction can be judged. The combination of laser measurement and photosensitive resistor reception has strong anti-interference ability. The laser beam is not easily interfered by external factors during transmission, and the photosensitive resistor can accurately capture the emitted laser signal, thus ensuring the accuracy of the measurement of the outer surface of the battery case.

[0020] Furthermore, it further includes a first test board and a second test board, and the first test board and the second test board are respectively arranged at both ends of the conveying structure;

[0021] The first test board has a scanning area in the shape of a "冂" character, and the N laser emitters are evenly arranged in the scanning area;

[0022] The second test board has a receiving area in the shape of a "冂" character, and the N photosensitive resistors are evenly arranged in the receiving area, and the N photosensitive resistors and the N laser emitters are in one-to-one correspondence.

[0023] By adopting the above solution, the first test board facilitates the installation of the laser emitters, and the second test board facilitates the installation of the photosensitive resistors. Since the measurement of the battery case mainly focuses on the measurement of the edge of the battery case, arranging the N laser emitters in the scanning area in the shape of a "冂" character can reduce the number of laser emitters and photosensitive resistors to be installed.

[0024] Furthermore, the first size measurement component includes a first distance measurement element, the second size measurement component is provided with a second distance measurement element, the object to be sorted is located between the first distance measurement element and the second distance measurement element, the first distance measurement element can measure the distance between it and the object to be sorted, and the second distance measurement element can measure the distance between it and the object to be sorted.

[0025] By adopting the above solution, setting the first distance measurement element and the second distance measurement element can obtain the length of the battery case from the first distance measurement element respectively, and the length of the battery case from the second distance measurement element. Then, combined with the distance between the first distance measurement element and the second distance measurement element, the length of the battery case in the first direction can be obtained.

[0026] Furthermore, the first size measuring component includes a first distance measuring element, and the second size measuring component is provided with a second distance measuring element. The object to be sorted is located between the first distance measuring element and the second distance measuring element. The first distance measuring element can measure the distance between it and the object to be sorted, and the second distance measuring element can measure the distance between it and the object to be sorted. The first distance measuring element is provided in the area enclosed by the scanning area of ​​the first test plate, and the second distance measuring element is provided in the area enclosed by the receiving area of ​​the second test plate.

[0027] By adopting the above solution, the scanning area in the area surrounded by the first test board is the lower middle area of ​​the first test board, and the first distance measuring element is arranged in this area to adapt to battery housings of more shapes.

[0028] Furthermore, the material dividing assembly includes a push rod and a push plate, the push rod and the push plate are fixedly connected, and have a second direction perpendicular to the first direction on a horizontal plane, and the push rod pushes the push plate to move along the second direction.

[0029] By adopting this solution, the push rod pushes the push plate to move in the second direction, which can push the battery shells conveyed on the conveyor structure away from the conveyor structure, thereby completing the sorting of the battery shells. The combination of the push rod and the push plate can also push heavier battery shells, thereby expanding the applicability of the sorting equipment.

[0030] Furthermore, a plurality of suction cups are provided on the push plate facing away from the push rod.

[0031] By adopting the above solution, the suction cup can absorb the battery shell, making the sorting action more reliable and avoiding sorting failure or damage to the battery shell caused by poor contact or unstable clamping.

[0032] Furthermore, an air pump is included, and the air pump is connected to the plurality of suction cups.

[0033] By adopting the above solution, the air pump can provide stable vacuum suction for the suction cup, ensuring that the battery shell is firmly adsorbed during the sorting process, thereby speeding up the sorting speed and improving the work efficiency of the entire production line.

[0034] Furthermore, it also includes an auxiliary conveying structure, which has a second direction perpendicular to the first direction on the horizontal plane, and the auxiliary conveying structure and the material dividing assembly are arranged on both sides of the conveying structure along the second direction.

[0035] By adopting the above solution, the auxiliary conveying structure and the material separation assembly work together, and the push plate, under the action of the push rod, pushes the battery shell onto the auxiliary conveying structure, thereby completing the sorting of the battery shell without the need for additional pauses or waiting time, thereby improving the sorting efficiency.

[0036] Furthermore, the material dividing components and the auxiliary conveying structure are each provided with two groups, and the two groups of the material dividing components are staggeredly arranged on both sides of the conveying structure, and each group of the auxiliary conveying structure corresponds to a group of the material dividing components arranged on both sides of the conveying structure.

[0037] By adopting the above solution and setting up two groups of material assemblies, qualified and unqualified battery shells can be sorted at the same time, greatly improving the efficiency of sorting. The staggered arrangement makes the distribution of battery shells on the conveying structure more convenient for the subsequent setting of the battery production line. That is, qualified battery shells are pushed to one side of the conveying structure by one group of material assemblies, which is convenient for subsequent battery production and assembly, and unqualified battery shells are pushed to the other side of the conveying structure by the other group of material assemblies, which is convenient for the recovery, adjustment and reuse of unqualified battery shells.

[0038] Furthermore, the thickness measuring component is an ultrasonic thickness gauge, and the ultrasonic thickness gauge has a plurality of ultrasonic probes, and the plurality of ultrasonic probes are all facing the transmission structure.

[0039] The ultrasonic thickness gauge, using this solution, is a non-contact measurement method that can measure thickness without direct contact with the battery casing surface, thus avoiding the risk of surface damage. More importantly, it can ensure accurate and timely measurements even on high-speed production lines.

[0040] In summary, the battery shell sorting device provided by the present invention has the following technical effects:

[0041] 1. The first dimension measurement component and the second dimension measurement component are arranged relative to each other along a first direction, and can accurately measure the external dimensions of the battery shell on the conveying structure, ensuring the accuracy of the battery shell external dimension measurement data.

[0051] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0052] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0053] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0055] See Figure 1 As shown, the utility model discloses a battery shell sorting equipment, including a conveying structure 1, a first size measuring component, a second size measuring component, a thickness measuring component 4 and a material separation component 5. The conveying structure 1 conveys objects along a first direction, and the first size measuring component and the second size measuring component are respectively arranged at the two ends of the conveying structure 1 in the first direction. The first size measuring component and the second size measuring component are used to measure the outer dimensions of the battery shell. The measuring component and the material separation component 5 are both arranged on one side of the conveying structure 1, and the first size measuring component and the second size measuring component are arranged opposite to each other along the first direction.

[0056] Specifically, the conveying structure 1 is a conveyor belt or a conveyor roller, which can convey objects moving along a first direction. The first direction is the direction in which the conveying structure 1 conveys the battery shell. In this application, it is mainly used to convey the battery shell. Furthermore, the conveying structure 1 is mainly used to convey the square battery steel shell. The first size measuring component and the second size measuring component are laser measuring components in this application, which can measure the three external dimensions of the length, width and height of the battery shell. The specific component type is not limited here. The thickness measuring component 4 is used to measure the wall thickness of the battery shell. The thickness measuring component 4 can use ultrasonic thickness measurement technology or magnetic induction thickness measurement technology. It can quickly measure the wall thickness of the battery shell. The specific type of thickness measuring component 4 is not limited here. The sorting component 5 is used to sort qualified battery shells and / or unqualified battery shells. The specific sorting component 5 can use a pushing method to sort the battery shells, or a manipulator to grab the battery shells, or use a blowing structure to sort the battery shells with smaller weight. When used, the appropriate sorting component 5 can be selected according to the specific type of battery shell and the assembly line design scheme. It is not limited here.

[0057] The working principle of the above structure is:

[0058] The equipment upstream of the battery production line places the battery shell on one end of the conveying structure 1 in the first direction, and the first size measuring component and the second size measuring component measure the length, width and height of the battery shell. After completing the measurement of the length, width and height, it can be known whether the outer dimensions of the battery shell are qualified based on the measurement data of the length, width and height. If it is unqualified, the material separation component 5 removes the battery shell from the conveying structure 1. If the outer dimensions of the battery shell are qualified, the conveying structure 1 moves and sends the battery shell to the measuring range of the thickness measuring component 4. The thickness measuring component 4 measures the wall thickness of the battery shell and determines whether the battery shell is qualified based on the measured data of the battery shell wall thickness. If it is qualified, the material separation component 5 sends the battery shell to the subsequent battery production line. If it is unqualified, the material separation component 5 sends the battery shell to the unqualified recycling line for subsequent processing and recycling.

[0059] See Figure 1 As shown, in some embodiments, in order to facilitate the control of the sorting device, the sorting device also includes a controller, the first size measurement component includes a detection signal sending module, the second size measurement component includes a detection signal receiving module for receiving detection information sent by the detection signal sending module, the detection signal sending module and the detection signal receiving module are both electrically connected to the controller, the battery housing is located between the detection signal sending module and the detection signal receiving module, and the battery housing blocks part of the detection information from being transmitted to the detection signal receiving module, so that the detection information received by the detection signal receiving module is compared with the standard size of the battery housing preset in the controller.

[0060] See Figure 1-Figure 4 As shown, further, the detection signal sending module is provided with N laser emitters 22, the N laser emitters 22 are arranged in a matrix, and all the laser emitters 22 emit lasers along the first direction, the detection signal receiving module is provided with N photoresistors 32, the N photoresistors 32 are arranged in a matrix, and the N photoresistors 32 correspond one-to-one to the N laser emitters 22, and each photoresistor 32 can receive the laser emitted by the corresponding laser emitter 22, and the N laser emitters 22 and the N photoresistors 32 are electrically connected to the controller.

[0061] Specifically, by setting N laser emitters 22 and N photosensitive resistors 32, and the N laser emitters 22 and the N photosensitive resistors 32 are arranged in one-to-one correspondence. The one-to-one correspondence between the laser emitter 22 and the photosensitive resistor 32 is as follows: the laser emitted by one laser emitter 22 shines on one corresponding photosensitive resistor 32. The specific measurement principle is as follows: when a battery case is placed on the conveying structure 1, some of the laser emitters 22 will be blocked by the battery case, resulting in the photosensitive resistor 32 corresponding to this part of the laser emitter 22 being unable to receive the laser, and further resulting in a relatively high resistance of this part of the photosensitive resistor 32, so that the dimensions of the upper end face of the battery case in the first direction can be judged, that is, two data of the width and height of the battery case are measured.

[0062] Refer to Figure 1-Figure 4 As shown, in some embodiments, in order to facilitate the installation of the first dimension measurement component and the second dimension measurement component, the sorting device further includes a first test board 2 and a second test board 3. The first test board 2 and the second test board 3 are respectively arranged at both ends of the conveying structure 1. The first test board 2 has a scanning area 21 in the shape of a reversed U. The N laser emitters 22 are evenly arranged in the scanning area 21. The second test board 3 has a receiving area 31 in the shape of a reversed U. The N photosensitive resistors 32 are evenly arranged in the receiving area 31, and the N photosensitive resistors 32 and the N laser emitters 22 are in one-to-one correspondence.

[0063] Specifically, since the measurement of the battery case mainly focuses on the measurement of the edge of the battery case, the vertical projections of the battery case on the first test board 2 and the second test board 3 will cover the lower regions of the first test board 2 and the second test board 3. Therefore, the N laser emitters 22 are arranged in the scanning area 21 in the shape of a reversed U, and the corresponding N photosensitive resistors 32 are arranged in the receiving area 31 in the shape of a reversed U. Laser emitters 22 / photosensitive resistors 32 are not arranged in the area that will definitely be blocked by the battery case, so as to reduce the number of laser emitters 22 and photosensitive resistors 32 that need to be installed.

[0064] Refer to Figure 1-Figure 4 As shown, in some embodiments, in order to facilitate the measurement of the dimensions of the battery case in the first direction, the first dimension measurement component includes a first distance measurement element 23, and the second dimension measurement component is provided with a second distance measurement element 33. The object to be sorted is located between the first distance measurement element 23 and the second distance measurement element 33. The first distance measurement element 23 can measure the distance between it and the object to be sorted, and the second distance measurement element 33 can measure the distance between it and the object to be sorted.

[0065] The specific working principle is as follows: the first distance measuring element 23 and the second distance measuring element 33 respectively measure the distance to the battery shell. Assuming that the first distance measuring element 23 measures the distance X to the battery shell, the second distance measuring element 33 measures the distance Y to the battery shell, and the distance between the first distance measuring element 23 and the second distance measuring element 33 is Z, the length L of the battery shell is: L = ZXY. This determines the length of the battery shell. Combined with the above width and height data, the length, width, and height of the battery shell are obtained, which facilitates comparison with the outer dimensions of a standard battery shell to determine whether the outer dimensions of the tested battery shell are consistent, that is, whether the outer dimensions of the tested battery shell are qualified.

[0066] It should be noted that: based on the structure of the controller, the first distance measuring element 23 and the second distance measuring element 33 are both electrically connected to the controller, so that the controller can centrally analyze and calculate the measured dimensions of the first distance measuring element 23 and the second distance measuring element 33.

[0067] See Figure 1-Figure 4 As shown, on the basis of setting the first test board 2 and the second test board 3 in the sorting equipment, in order to improve the applicable range of the first ranging element 23 and the second ranging element 33 for ranging, the first ranging element 23 is arranged in the area enclosed by the scanning area 21 of the first test board 2, and the second ranging element 33 is arranged in the area enclosed by the receiving area 31 of the second test board 3.

[0068] Specifically, since the vertical projection of the battery shell on the first test plate 2 and the second test plate 3 will cover the lower area of ​​the first test plate 2 and the second test plate 3, the first ranging element 23 is arranged in the area enclosed by the scanning area 21 of the first test plate 2, and the second ranging element 33 is arranged in the area enclosed by the receiving area 31 of the second test plate 3, thereby ensuring that both the first ranging element 23 and the second ranging element 33 can complete the measurement of the battery shell, thereby ensuring the accuracy and applicability of the measurement length of the sorting equipment of the present application.

[0069] See Figure 1 and Figure 5 As shown, in some embodiments, the material distribution assembly 5 includes a push rod 51 and a push plate 52, which are fixedly connected and have a second direction perpendicular to the first direction on a horizontal plane. The push rod 51 pushes the push plate 52 to move along the second direction.

[0070] Specifically, the material distribution assembly 5 includes a push rod 51 and a push plate 52. The push rod 51 is fixedly connected to the push plate 52, that is, the push plate 52 is fixedly installed at the movable end of the push rod 51, so that the push rod 51 can push the push plate 52 to move. On the horizontal plane, there is a second direction perpendicular to the first direction. The horizontal plane is the surface of the conveying structure 1 used to convey the battery shell. It is best for the corresponding push rod 51 to push the push plate 52 to move in the second direction. Since the second direction is perpendicular to the first direction, the push rod 51 pushes the push plate 52 to move in the second direction, which can push the battery shell away from the conveying structure 1 with the shortest movement distance. In addition, in the case of some square shells, pushing the battery shell in the second direction can also avoid problems such as the square shell tilting and rotating during the process of being pushed away.

[0071] It should be noted that: based on the structure of the controller, the push rod 51 is electrically connected to the controller so that the push rod 51 is activated accordingly based on whether the battery shells need to be sorted, thereby driving the push plate 52 to complete the material removal.

[0072] See Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, a plurality of suction cups 521 are provided on the side of the push plate 52 facing away from the push rod 51. By providing multiple suction cups 521 on the side of the push plate 52 facing away from the push rod 51, when the push plate 52 drags the battery housing, the suction cups 521 will generate a certain degree of adsorption with the battery housing, further preventing the battery housing from rotating when the push plate 52 pushes the battery housing. The specific number of suction cups 521 and the position distribution of the multiple suction cups 521 can be selected according to actual conditions and are not limited here. In this embodiment, the multiple suction cups 521 are arranged on the push plate 52 in a matrix.

[0073] See Figure 1 、 Figure 5 and Figure 6 As shown, further, based on the structure that multiple suction cups 521 are provided on the push plate 52, the sorting equipment also includes an air pump 522, and the air pump 522 is connected to the multiple suction cups 521. The air pump 522 can be connected to the multiple suction cups 521 through a pipeline. In this embodiment, the air pump 522 is arranged inside the push plate 52, and the multiple suction cups 521 are all connected to the guide groove 523 provided inside the push plate 52. The air pump 522 is connected to the multiple suction cups 521 through the guide groove 523. When the suction cup 521 needs to maintain a negative pressure state, the air in the suction cup 521 is discharged to the air pump 522 through the guide groove 523 in turn, thereby improving the adsorption strength between the suction cup 521 and the battery shell.

[0074] It should be noted that: based on the structure of the controller, the air pump 522 is electrically connected to the controller so that the air pump 522 is started accordingly based on whether the battery shells need to be sorted.

[0075] See Figure 1 As shown, in some embodiments, in order to improve the production efficiency of the battery production line, the sorting equipment further includes an auxiliary conveying structure 6, which is arranged on both sides of the conveying structure 1 along the second direction with the material separation component 5. The auxiliary conveying structure 6 is used to convey the battery shells sorted by the material separation component 5. The auxiliary conveying structure 6 can be a conveyor belt, a conveyor roller, or other conveying robot, etc., which can convey the battery shells sorted by the material separation component 5 to the equipment corresponding to the subsequent processing step according to the subsequent production process. In this embodiment, the auxiliary conveying structure 6 is a conveyor belt. When the material separation component 5 adopts the structure of the push plate 52 and the push rod 51, the auxiliary conveying structure 6 is adopted, and the auxiliary conveying structure 6 and the material separation component 5 are arranged on both sides of the conveying structure 1 along the second direction. When the push plate 52 pushes the battery shell away from the conveying structure 1, it just pushes the battery shell onto the auxiliary conveying structure 6. The auxiliary conveying structure 6 transports the battery shell to the equipment corresponding to the subsequent processing step, thereby simplifying the sorting structure and sorting steps, without additional pauses or waiting time, thereby improving the sorting efficiency and achieving the purpose of improving the production efficiency of the battery production line.

[0076] It should be noted that: based on the structure of the controller, the auxiliary transmission structure 6 is electrically connected to the controller so that the controller can adjust the operation of the auxiliary transmission structure 6 based on the power-on signal.

[0077] See Figure 1 As shown, in some embodiments, in order to further simplify the sorting structure and sorting steps, two groups of material separation components 5 and auxiliary conveying structures 6 are provided, and the two groups of material separation components 5 are staggered on both sides of the conveying structure 1, and each group of auxiliary conveying structures 6 corresponds to a group of material separation components 5 arranged on both sides of the conveying structure 1.

[0078] Specifically, two groups of the material separation components 5 and the auxiliary conveying structure 6 are each provided, wherein the two groups of material separation components 5 are staggered on either side of the conveying structure 1, that is, during the material separation process of the material separation components 5, the movement of the push plates 52 of the two groups of material separation components 5 will not interfere with each other, and each group of auxiliary conveying structures 6 is provided on either side of the conveying structure 1 corresponding to one group of material separation components 5, that is, on the basis of the staggered arrangement of the material separation components 5, the auxiliary conveying structures 6 are provided along the second direction on the opposite side of the corresponding material separation components 5 located on the conveying structure 1. By providing two groups of material separation components 5, qualified and unqualified battery shells can be sorted simultaneously, that is, battery shells determined to be qualified after measurement are pushed onto one of the auxiliary conveying structures 6 by one of the material separation components 5, completing the sorting of qualified battery shells, and battery shells determined to be unqualified after measurement are pushed onto the other auxiliary conveying structure 6 by the other material separation component 5, completing the sorting of unqualified battery shells.

[0079] The two groups of material components 5 are selected to be respectively arranged on both sides of the conveying structure 1, which is also helpful for the design of the subsequent battery production line. Specifically: the two groups of material components 5 are selected to be respectively arranged on both sides of the conveying structure 1, and the corresponding two groups of auxiliary conveying structures 6 are respectively arranged on both sides of the conveying structure 1. During the sorting process, qualified battery shells are conveyed to the equipment of subsequent processing procedures through the auxiliary conveying structure 6 located on one side of the conveying structure 1, and unqualified battery shells are conveyed to the process equipment for battery shell recovery, processing and reuse through the auxiliary conveying structure 6 located on the other side of the conveying structure 1. That is, the qualified battery shells and unqualified battery shells are divided into the subsequent process production lines that may be involved after sorting, thereby facilitating the design of subsequent battery production lines.

[0080] See Figure 1 and Figure 7 As shown, in some embodiments, in order to accelerate the measurement of the battery shell wall thickness, ultrasonic technology is used to measure the wall thickness. The corresponding thickness measuring component 4 is an ultrasonic thickness gauge, which has multiple ultrasonic probes 41. The multiple ultrasonic probes 41 are all facing the conveying structure 1. Specifically, because the ultrasonic thickness gauge is a non-contact measurement method, it can measure the thickness without direct contact with the battery shell surface, thereby avoiding the risk of possible damage to the battery shell surface. More importantly, it can ensure the accuracy and timeliness of measurement even on a high-speed production line.

[0081] It should be noted that: based on the structure of the controller, the ultrasonic thickness gauge is electrically connected to the controller so that the ultrasonic thickness gauge is activated based on the movement of the battery shell to perform corresponding measurements on the battery shell.

[0082] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
