Description

Technical Field

[0001] The present application relates to the field of defect detection technology, and in particular to a defect detection device and a battery production line. Background Art

[0002] With the development demand of electronic application equipment, the lithium battery industry has also ushered in rapid development. In the prior art, some battery packs are mostly composed of a combination of batteries, and the outer shell of the battery is usually stamped. Various defects often appear in the process of battery shell molding, such as blackening of the surface, stains, oxidation water stains, scratches or edge wrinkles. Defective battery shells can cause various problems in the resulting batteries, so it is necessary to perform defect detection and screening on the battery shells before battery production. However, in the related art, most of the devices for defect detection of battery shells have a relatively complex structure, occupy a large space volume, and the time required during the detection process is also relatively long, which makes the detection efficiency low and the detection cost high. Summary of the invention

[0003] In view of the above problems, the present application provides a defect detection device, which can improve the efficiency of the battery shell during the detection process to reduce the time required for the detection process.

[0004] In the first aspect, the present application provides a defect detection device, including a conveying mechanism, an identification mechanism, a flipping mechanism and a detection mechanism. The conveying mechanism is used to convey an object to be detected; the identification mechanism is used to identify the object to be detected conveyed to a first preset position; the flipping mechanism can flip the object to be detected at the first preset position and transfer the object to be detected to a second preset position; the detection mechanism is used to perform defect detection on the surface to be detected of the object to be detected at the second preset position.

[0005] When the defect detection device provided by the embodiment of the present application is used to detect defects in the battery shell, the object to be detected is the battery shell. The conveying mechanism is used to convey the battery shell. When the conveying mechanism conveys the battery shell to the first preset position, the recognition mechanism can identify the battery shell at the first preset position. When the recognition mechanism identifies that there is a battery shell at the first preset position, the flipping mechanism can flip the battery shell at the first preset position and transfer the battery shell to the second preset position. At this time, the detection mechanism performs defect detection on the surface to be detected of the battery shell at the second preset position. Since the battery shell is directly flipped by the flipping mechanism during this detection process, the battery shell reduces the additional moving process during the detection process, reduces the beat, and takes less time to detect, thereby making the detection efficiency higher and the detection cost lower.

[0006] In some embodiments, the flip mechanism includes a flip shaft and a clamping assembly mounted on the flip shaft; the clamping assembly is used to clamp the object to be detected, and the flip shaft can drive the clamping assembly to rotate around its own rotation axis, so that the object to be detected flips from the first preset position to the second preset position. The clamping assembly can be a clamping plate or a clamping claw clamp, etc. After the battery housing at the first preset position is clamped by the clamping plate or the clamping claw clamp, the flip shaft is rotated around its own rotation axis, so that the battery housing is flipped from the first preset position to the second preset position, which is very simple and convenient.

[0007] In some embodiments, the clamping assembly includes a mounting plate, a first clamping plate and a second clamping plate; the mounting plate is mounted on the flip shaft, the first clamping plate and the second clamping plate are arranged oppositely along the axial direction of the flip shaft and connected to the mounting plate, and the first clamping plate and the second clamping plate can be close to or away from each other, so that the first clamping plate and the second clamping plate abut and clamp the object to be detected. When the battery shell is transported to the first preset position by the conveying mechanism, the recognition mechanism recognizes that the first preset position has a battery shell. The flip shaft can rotate around its own rotation axis so that the first clamping plate and the second clamping plate can rotate to the outer periphery of the battery shell, and then the first clamping plate and the second clamping plate are close to each other to clamp the battery shell, and the flip shaft continues to rotate in the opposite direction around its own rotation axis so that the battery shell can be flipped 180° to the second preset position, at which time the first clamping plate and the second clamping plate are away from each other, and the first clamping plate and the second clamping plate are separated from the battery shell, and the flip shaft rotates to the initial angle again, and the battery shell is located at the second preset position.

[0008] In some embodiments, the mounting plate includes a first mounting plate and a second mounting plate; in some embodiments, the first mounting plate is configured with a plurality of first mounting portions spaced axially along the flip axis, and the first clamping plate is detachably connected to one of the first mounting portions. By configuring a plurality of first mounting portions on the first mounting plate, and the first clamping plate is detachably connected to one of the first mounting portions, the distance between the first clamping plate and the second clamping plate can be greatly changed, thereby enabling the clamping assembly to clamp battery shells of different sizes, so that the defect detection device can detect battery shells of different specifications and sizes, and has stronger adaptability.

[0009] In other embodiments, the second mounting plate is configured with a plurality of second mounting portions spaced axially along the flip axis, and the second clamping plate is detachably connected to one of the second mounting portions. By configuring a plurality of second mounting portions on the second mounting plate, and the second clamping plate is detachably connected to one of the second mounting portions, the distance between the second clamping plate and the first clamping plate can be greatly changed, thereby enabling the clamping assembly to clamp battery shells of different sizes, so that the defect detection device can detect battery shells of different specifications and sizes, and has stronger adaptability.

[0010] In some embodiments, the identification mechanism is disposed between the first mounting plate and the second mounting plate. By installing the identification mechanism between the first mounting plate and the second mounting plate, that is, installing the identification mechanism on the side of the conveyor belt at the first preset position, when the conveyor mechanism conveys the battery housing to between the first mounting plate and the second mounting plate, the identification mechanism can identify it more quickly, and the first clamping plate installed on the first mounting plate and the second clamping plate installed on the second mounting plate can quickly clamp the battery housing at the first preset position, thereby effectively reducing the detection cycle and making the detection efficiency higher.

[0011] In some embodiments, a support mechanism is further included, wherein the support mechanism and the conveying mechanism are spaced apart along a first direction, and the first direction is arranged at an angle to the conveying direction of the conveying mechanism; the support mechanism is used to support the object to be inspected that is flipped to a second preset position. The battery housing at the second preset position is supported by the support mechanism, so that the battery housing can be inspected for defects on the surface to be inspected of the battery housing at the second preset position through the inspection mechanism.

[0012] In some embodiments, the support mechanism includes a vertical support plate and a horizontal support plate; the vertical support plate is connected to the horizontal support plate, and the side of the horizontal support plate facing away from the vertical support plate is used to support the object to be detected. When the flipping mechanism flips the battery housing from the first preset position to the second preset position, the horizontal support plate supports the battery housing, and the detection mechanism performs defect detection on the surface to be detected of the battery housing on the horizontal support plate. By connecting and cooperating with each other, the entire support mechanism occupies a smaller area and the layout is more compact.

[0013] In some embodiments, the support mechanism further includes a first adjustment component, which is mounted on the horizontal support plate, and the first adjustment component is configured with a receiving space, and the receiving space is used to receive and clamp the object to be detected. The first adjustment component is configured with a receiving space, and by adjusting the size of the receiving space, the battery housing can be received and clamped in the receiving space, so that the position of the battery housing in the second preset position is kept with high accuracy, and it is not easy to shake or flip, etc., so that the detection mechanism has a better photographing effect and higher detection accuracy when performing visual photography detection.

[0014] In some embodiments, the first adjustment assembly includes a first adjustment plate and two clamping plates; the first adjustment plate is mounted on the horizontal support plate, the two clamping plates are arranged opposite to each other, and at least one of the two clamping plates is slidably mounted on the first adjustment plate, and a receiving space is formed between the two clamping plates. By sliding at least one of the two clamping plates relative to the first adjustment plate, the size of the receiving space is changed, thereby achieving the clamping of the clamping plate on the battery housing, which is very simple and convenient.

[0015] In some embodiments, the support mechanism further includes a second adjustment component, which is slidably connected to the vertical support plate and is used to adjust the height of the horizontal support plate relative to the ground. The height of the horizontal support plate relative to the ground is adjusted by the second adjustment component, so that the support mechanism can be adaptively raised and lowered according to battery shells of different heights, thereby better adapting to the detection requirements of battery shells of different heights, making the defect detection device more adaptable.

[0016] In some embodiments, the second adjustment assembly includes a second adjustment plate and a locking plate; the second adjustment plate is slidably connected to the vertical support plate, the locking plate is detachably connected to the second adjustment plate and the vertical support plate, and the locking plate is used to lock the position of the second adjustment plate relative to the vertical support plate. Through the cooperation between the second adjustment plate and the locking plate, the defect detection device is very simple and convenient when adjusting the height of the support mechanism. In some embodiments, a scale is also provided on the second adjustment plate, which is convenient for the user to observe and adjust the locking height of the second adjustment plate.

[0017] In some embodiments, the number of identification mechanisms is at least two, and at least two identification mechanisms are arranged at intervals along the conveying direction of the conveying mechanism, and the number of flipping mechanisms and detection mechanisms is adapted to the identification mechanisms. By providing at least two identification mechanisms, and the number of flipping mechanisms and detection mechanisms is adapted to the identification mechanisms, the defect detection device can simultaneously detect multiple battery shells, thereby reducing the average time required for detecting a single battery shell, reducing the beat of the entire detection process, and increasing the detection efficiency.

[0018] In a second aspect, the present application provides a battery production line, which includes the defect detection device described in any one of the above embodiments, and also includes a grasping and releasing device, which is used to grasp the object to be detected and place it on a conveying mechanism.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0039] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0040] In the prior art, some battery packs are mostly made of batteries, and the outer shell of the battery is usually stamped. Various defects often appear in the process of battery shell molding, such as black surface, surface stains, surface oxidation water stains, surface scratches, surface convex points, surface concave points, stretch marks or edge wrinkles, etc. Defective battery shells will cause various problems in the produced batteries, so it is necessary to perform defect detection and screening on the battery shells before battery production.

[0041] The industry usually uses visual inspection cameras to detect defects in battery shells. After the upper surface inspection of the battery shell is completed, the battery shell is transported to the material picking position of the handling structure through the conveyor line. The multi-axis handling mechanism erected around the conveyor line transports the battery shell to the flipping station. After the flipping mechanism is flipped, the handling robot transports the aluminum shell to the inspection station, and the visual inspection camera performs defect inspection on the battery shell surface. However, the current handling mechanism has a complex structure, occupies a large space volume, and has a high production cycle. At the same time, the battery shell cannot directly complete a 180° flip from the upper surface to the bottom surface, which cannot meet the production cycle requirements, and the time required during the inspection process is also relatively long, which makes the inspection efficiency low and the inspection cost high.

[0042] Based on the above considerations, in order to solve the technical problems of low efficiency and long time spent in the detection process of battery shells, the inventors have designed a defect detection device after in-depth research. By setting a flip mechanism on the defect detection device, when the flip mechanism clamps the battery shell and flips it to the second preset position, the detection mechanism can directly perform defect detection on the surface to be detected of the battery shell at the second preset position, thereby reducing the additional moving process of the battery shell during the detection process, reducing the beat, and taking less time for the detection process, thereby making the detection efficiency higher and the detection cost lower.

[0043] The battery shell detected by the defect detection device disclosed in the embodiment of the present application finally forms a battery cell and a battery pack, which can be used in, but not limited to, electrical devices such as vehicles, ships or aircraft. After the defect detection device disclosed in the embodiment of the present application performs defect detection on the battery shell, the battery shell and the battery are combined to form a battery cell, a battery pack, etc. to form a power supply system of the electrical device, which is conducive to improving the stability of battery performance and battery life.

[0044] The embodiment of the present application provides an electric device using a battery as a power source, and the electric device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0045] Please refer to Figures 1 to 3. Figure 1 shows a schematic diagram of a defect detection device provided in some embodiments of the present application. Figure 2 shows a partial enlarged view of A of the defect detection device shown in Figure 1. Figure 3 shows a partial enlarged view of B of the defect detection device shown in Figure 2. The defect detection device provided in some embodiments of the present application includes a conveying mechanism 100, an identification mechanism 200, a flipping mechanism 300 and a detection mechanism (not shown in the figure). The conveying mechanism 100 is used to convey the object to be detected; the identification mechanism 200 is used to identify the object to be detected conveyed to the first preset position 130; the flipping mechanism 300 can flip the object to be detected in the first preset position 130 and transfer the object to be detected to the second preset position 140; the detection mechanism is used to perform defect detection on the surface to be detected of the object to be detected in the second preset position 140.

[0046] The conveying mechanism 100 is a mechanism capable of conveying materials, such as a conveying chain, a conveying belt 110 or a conveying roller. The object to be detected is placed on the conveying chain, the conveying belt 110 or the conveying roller. Then, a driving member drives the conveying chain, the conveying belt 110 or the conveying roller to rotate, thereby realizing the mobile conveying of the object to be detected. Please refer to FIG. 1. In some embodiments, the conveying mechanism 100 includes a conveying belt 110 and a first driving member 120. The first driving member 120 is used to drive the conveying belt 110 to perform a closed loop motion, and the object to be detected is placed on the conveying belt 110 for mobile conveying.

[0047] The identification mechanism 200 is a mechanism capable of identifying the object to be detected, such as a photoelectric detector, an infrared sensor or a Hall sensor, etc. When there is an object to be detected at the first preset position 130, the detection signal emitted by the identification mechanism 200 can be received by the object to be detected or a receiving signal can be fed back to the identification mechanism 200, so that the identification mechanism 200 can determine that there is an object to be detected here.

[0048] The detection mechanism can be a visual detection camera, which takes pictures of the surface to be detected to detect whether the object to be detected has surface blackening, surface stains, surface oxidation water stains, surface scratches, surface convex points, surface concave points, stretch marks, edge wrinkles and other defects.

[0049] When the defect detection device provided by the embodiment of the present application performs defect detection on the battery housing 500, the object to be detected is the battery housing 500. The conveying mechanism 100 is used to convey the battery housing 500. When the conveying mechanism 100 conveys the battery housing 500 to the first preset position 130, the identification mechanism 200 can identify the battery housing 500 at the first preset position 130. When the identification mechanism 200 identifies that the first preset position 130 has a battery housing 500, the flipping mechanism 300 can flip the battery housing 500 at the first preset position 130 and transfer the battery housing 500 to the second preset position 140. At this time, the detection mechanism performs defect detection on the surface to be detected of the battery housing 500 at the second preset position 140. Since the battery housing 500 is directly flipped by the flipping mechanism 300 during the detection process, the battery housing 500 reduces the additional moving process during the detection process, reduces the beat, and takes less time for the detection process, thereby making the detection efficiency higher and the detection cost lower.

[0050] In some of the embodiments, the identification mechanism 200, the flipping mechanism 300 and the detection mechanism are all arranged on the conveying mechanism 100, so that the structure of the entire defect detection device is relatively compact and occupies a small space.

[0051] It should be noted that the object to be detected can be any structure with detection requirements, such as the battery housing 500, a battery cell assembled by the battery housing 500 and a battery, etc., and there is no special limitation on this.

[0052] The following describes the structure of the defect detection device in detail, with the object to be detected being a battery housing 500. Referring to Figures 1 to 3, the flipping mechanism 300 of the defect detection device provided in some embodiments of the present application includes a flip shaft 310 and a clamping assembly 320 mounted on the flip shaft 310; the clamping assembly 320 is used to clamp the object to be detected, and the flip shaft 310 can drive the clamping assembly 320 to rotate around its own rotation axis, so that the object to be detected flips from the first preset position 130 to the second preset position 140.

[0053] The flip shaft 310 is a rotating shaft structure that can rotate around its own rotation axis. The rotation axis of the flip shaft 310 is parallel to the conveying direction of the conveying mechanism 100 , both of which are the yy′ direction in FIG. 1 .

[0054] The clamping assembly 320 can be a structure such as a clamping plate or a clamping claw clamp. After the battery housing 500 at the first preset position 130 is clamped by the clamping plate or the clamping claw clamp, the flip axis 310 is rotated around its own rotation axis parallel to the yy' direction in Figure 1, so that the battery housing 500 is flipped from the first preset position 130 to the second preset position 140, which is very simple and convenient.

[0055] In some embodiments, the flip mechanism 300 further includes a second driving member 330, which is connected to the flip shaft 310 and is used to drive the flip shaft 310 to rotate around its own rotation axis. Optionally, the second driving member 330 is a motor.

[0056] Please refer to Figures 2 and 3. The clamping assembly 320 of the defect detection device provided in some embodiments of the present application includes a mounting plate 321, a first clamping plate 322 and a second clamping plate 323; the mounting plate 321 is installed on the flip shaft 310, and the first clamping plate 322 and the second clamping plate 323 are arranged relatively to each other along the axial direction of the flip shaft 310 and are connected to the mounting plate 321. Specifically, the axial direction of the flip shaft 310 is the yy' direction in Figure 1, and the first clamping plate 322 and the second clamping plate 323 can approach or move away from each other so that the first clamping plate 322 and the second clamping plate 323 are abutted and clamped against the object to be detected.

[0057] A slide groove may be provided on the mounting plate 321, and at least one of the first clamping plate 322 and the second clamping plate 323 may be provided with a slider matching with the slide groove, and the slider slides in the slide groove, thereby achieving the first clamping plate 322 and the second clamping plate 323 being brought closer to or farther away from each other.

[0058] When the battery housing 500 is transported to the first preset position 130 by the transport mechanism 100, the identification mechanism 200 identifies that the first preset position 130 has the battery housing 500. The flip shaft 310 can rotate around its own rotation axis, so that the first clamping plate 322 and the second clamping plate 323 can rotate to the periphery of the battery housing 500, and then the first clamping plate 322 and the second clamping plate 323 are close to each other to clamp the battery housing 500, and the flip shaft 310 continues to rotate in the opposite direction around its own rotation axis, so that the battery housing 500 can be flipped 180° to the second preset position 140, at which time the first clamping plate 322 and the second clamping plate 323 are away from each other, and the first clamping plate 322 and the second clamping plate 323 are separated from the battery housing 500, and the flip shaft 310 rotates to the initial angle again, and the battery housing 500 is located at the second preset position.

[0059] Please continue to refer to Figures 2 and 3. The mounting plate 321 of the defect detection device provided in some embodiments of the present application includes a first mounting plate 3211 and a second mounting plate 3212; in some embodiments, the first mounting plate 3211 is constructed with a plurality of first mounting portions 32111 arranged at intervals along the axial direction of the flip axis 310. Specifically, the axial direction of the flip axis 310 is the yy' direction in Figure 1, and the first clamping plate 322 is detachably connected to one of the first mounting portions 32111.

[0060] The first mounting plate 3211 may be configured with a plurality of groups of first mounting holes spaced apart along the axial direction of the flip shaft 310, each group of first mounting holes forming a first mounting portion 32111, and each group of first mounting holes may include at least two first mounting holes spaced apart, thereby reducing the possibility of relative rotation between the first clamping plates 322 after they are mounted on the first mounting plate 3211. The first clamping plate 322 is mounted and connected to one of the groups of first mounting holes through a connecting piece, thereby realizing a detachable connection between the first clamping plate 322 and one of the first mounting portions 32111.

[0061] By constructing multiple first mounting parts 32111 on the first mounting plate 3211, and the first clamping plate 322 is detachably connected to one of the first mounting parts 32111, the distance between the first clamping plate 322 and the second clamping plate 323 can be greatly changed, so that the clamping assembly 320 can clamp battery shells 500 of different sizes, so that the defect detection device can detect battery shells 500 of different specifications and sizes, and has stronger adaptability.

[0062] In some other embodiments, the second mounting plate 3212 is configured with a plurality of second mounting portions 32121 spaced apart from each other along the axial direction of the flip shaft 310 , and the second clamping plate 323 is detachably connected to one of the second mounting portions 32121 .

[0063] The second mounting plate 3212 may be configured with multiple groups of second mounting holes spaced apart along the axial direction of the flip shaft 310, each group of second mounting holes forming a second mounting portion 32121, and each group of second mounting holes may include at least two spaced apart second mounting holes, thereby reducing the possibility of relative rotation between the second clamping plates 323 after they are mounted on the second mounting plate 3212. The second clamping plate 323 is mounted and connected to one of the groups of second mounting holes through a connecting piece, thereby realizing a detachable connection between the second clamping plate 323 and one of the second mounting portions 32121.

[0064] By constructing multiple second mounting parts 32121 on the second mounting plate 3212, and the second clamping plate 323 is detachably connected to one of the second mounting parts 32121, the distance between the second clamping plate 323 and the first clamping plate 322 can be greatly changed, so that the clamping assembly 320 can clamp battery shells 500 of different sizes, so that the defect detection device can detect battery shells 500 of different specifications and sizes, and has stronger adaptability.

[0065] Please refer to Figures 1 to 3. The identification mechanism 200 of the defect detection device provided in some embodiments of the present application is arranged between the first mounting plate 3211 and the second mounting plate 3212.

[0066] The identification mechanism 200 is installed between the first mounting plate 3211 and the second mounting plate 3212, that is, the identification mechanism 200 is installed on the side of the conveyor belt 110 at the first preset position 130, so that when the conveying mechanism 100 conveys the battery housing 500 to between the first mounting plate 3211 and the second mounting plate 3212, the identification mechanism 200 can identify it more quickly, and enable the first clamping plate 322 installed on the first mounting plate 3211 and the second clamping plate 323 installed on the second mounting plate 3212 to quickly clamp the battery housing 500 at the first preset position 130, thereby effectively reducing the detection cycle and making the detection efficiency higher.

[0067] Please refer to Figures 1 to 4, Figure 4 shows a schematic diagram of the support mechanism 400 in the defect detection device shown in Figure 1 supporting the battery housing 500. The defect detection device provided in some embodiments of the present application further includes a support mechanism 400, the support mechanism 400 and the conveying mechanism 100 are arranged at intervals along a first direction, and the first direction is arranged at an angle to the conveying direction of the conveying mechanism 100; the support mechanism 400 is used to support the object to be detected flipped to the second preset position 140.

[0068] The support mechanism 400 may be a support plate structure or a support frame structure, and the battery housing 500 at the second preset position 140 is supported by the support mechanism 400, so that the battery housing 500 can be inspected for defects on the surface to be inspected at the second preset position 140 through the inspection mechanism.

[0069] Please refer to Figure 4. The support mechanism 400 of the defect detection device provided in some embodiments of the present application includes a vertical support plate 410 and a horizontal support plate 420. The vertical support plate 410 is connected to the horizontal support plate 420, and the side of the horizontal support plate 420 facing away from the vertical support plate 410 is used to support the object to be detected.

[0070] The vertical support plate 410 is used to support the horizontal support plate 420. The vertical support plate 410 and the horizontal support plate 420 can be made of any material, such as metal, plastic or wood, etc., without any special limitation.

[0071] In some embodiments, the vertical support plate 410 includes two, namely a first vertical plate 411 and a second vertical plate 412. The first vertical plate 411 and the second vertical plate 412 are opposite to each other and spaced apart. The first vertical plate 411 and the second vertical plate 412 are used together to support the transverse support plate 420, so that the supporting effect for the transverse support plate 420 is better.

[0072] When the flipping mechanism 300 flips the battery housing 500 from the first preset position 130 to the second preset position 140, the horizontal support plate 420 supports the battery housing 500, and the detection mechanism performs defect detection on the to-be-detected surface of the battery housing 500 on the horizontal support plate 420. By connecting and cooperating the vertical support plate 410 and the horizontal support plate 420, the entire support mechanism 400 occupies a smaller area and has a more compact layout.

[0073] Please refer to Figure 4. The support mechanism 400 of the defect detection device provided in some embodiments of the present application also includes a first adjustment component 430. The first adjustment component 430 is installed on the horizontal support plate 420. The first adjustment component 430 is configured with a accommodating space, which is used to accommodate and clamp the object to be inspected.

[0074] The first adjustment component 430 can be slidably installed on the horizontal support plate 420 to facilitate adjustment of the installation position of the first adjustment component 430 and the size of the accommodating space, and the first adjustment component 430 and the horizontal support plate 420 are detachably connected to facilitate replacement of the first adjustment component 430.

[0075] The first adjustment component 430 is configured with an accommodating space. By adjusting the size of the accommodating space, the battery housing 500 can be accommodated and snapped into the accommodating space, so that the position of the battery housing 500 at the second preset position 140 is maintained with high precision and is not prone to shaking or flipping. Therefore, when the detection mechanism performs visual photography detection, the photography effect is better and the detection accuracy is higher.

[0076] Please refer to Figure 4. The first adjustment component 430 of the defect detection device provided in some embodiments of the present application includes a first adjustment plate 431 and two clamping plates 432; the first adjustment plate 431 is installed on the horizontal support plate 420, the two clamping plates 432 are arranged opposite to each other, and at least one of the two clamping plates 432 is slidably installed on the first adjustment plate 431, and a accommodating space is formed between the two clamping plates 432.

[0077] The two clamps 432 are arranged opposite to each other along the xx' direction in Figure 1, and a slide groove is constructed on the first adjustment plate 431. At least one of the two clamps 432 is constructed with a slider, and the slider is slidably connected to the slide groove. The slider slides in the slide groove, thereby changing the distance between the two clamps 432.

[0078] By sliding at least one of the two clamping plates 432 relative to the first adjusting plate 431 , the size of the accommodating space is changed, thereby achieving the clamping of the battery housing 500 by the clamping plates 432 , which is very simple and convenient.

[0079] Please refer to Figure 4. The support mechanism 400 of the defect detection device provided in some embodiments of the present application also includes a second adjustment component 440, which is slidably connected to the vertical support plate 410 and is used to adjust the height of the horizontal support plate 420 relative to the ground.

[0080] The second adjustment component 440 is slidably connected to the vertical support plate 410, so that by adjusting the connection position of the second adjustment component 440 relative to the vertical support plate 410, the height of the structure composed of the second adjustment component 440 and the vertical support plate 410 relative to the ground is achieved, thereby achieving the adjustment of the height of the horizontal support plate 420 relative to the ground.

[0081] The height of the horizontal support plate 420 relative to the ground is adjusted by the second adjustment component 440, so that the support mechanism 400 can be adaptively raised and lowered according to the battery shells 500 of different heights, and can thus better adapt to the inspection requirements of battery shells 500 of different heights, making the defect detection device more adaptable.

[0082] Please refer to Figure 4. The second adjustment component 440 of the defect detection device provided in some embodiments of the present application includes a second adjustment plate 441 and a locking plate 442; the second adjustment plate 441 is slidably connected to the vertical support plate 410, and the locking plate 442 is detachably connected to the second adjustment plate 441 and the vertical support plate 410, and the locking plate 442 is used to lock the position of the second adjustment plate 441 relative to the vertical support plate 410.

[0083] The second adjustment plate 441 is slidably connected to the vertical support plate 410, and the second adjustment plate 441 is adjusted relative to the vertical support plate 410, and finally locked by the locking plate 442, so that the second adjustment assembly 440 can adjust the height of the horizontal support plate 420 relative to the ground. Optionally, locking holes are respectively configured on the vertical support plate 410, the second adjustment plate 441 and the locking plate 442, and the locking member is connected to the second adjustment plate 441 and the vertical support plate 410 by passing through the locking plate 442, so that the locking plate 442 can lock the position of the second adjustment plate 441 relative to the vertical support plate 410.

[0084] Through the cooperation between the second adjustment plate 441 and the locking plate 442, the defect detection device is very simple and convenient when adjusting the height of the support mechanism 400. In some embodiments, a scale is also provided on the second adjustment plate 441, which is convenient for the user to observe and adjust the locking height of the second adjustment plate 441, which is more convenient.

[0085] Please refer to FIG. 1 and FIG. 2 . The number of identification mechanisms 200 of the defect detection device provided in some embodiments of the present application is at least two, and at least two identification mechanisms 200 are arranged at intervals along the conveying direction of the conveying mechanism 100, and the number of the flipping mechanism 300 and the detection mechanism is adapted to the identification mechanism 200. By setting at least two identification mechanisms 200, and the number of the flipping mechanism 300 and the detection mechanism is adapted to the identification mechanism 200, the defect detection device can simultaneously detect multiple battery shells 500, thereby reducing the average time required for the detection of a single battery shell 500, reducing the beat of the entire detection process, and improving the detection efficiency.

[0086] The present application also provides a battery production line, which includes the defect detection device described in any of the above embodiments, and also includes a grasping and releasing device, which is used to grasp the object to be inspected, that is, the battery shell 500 and put it on the conveying mechanism 100. At least one of the above technical effects can be achieved through this battery production line.

[0087] The defect detection device provided in the embodiment of the present application includes a conveying mechanism 100, an identification mechanism 200, a flipping mechanism 300, a detection mechanism and a supporting mechanism 400. The conveying mechanism 100 is used to convey the object to be detected; the identification mechanism 200 is used to identify the object to be detected conveyed to the first preset position 130. The flipping mechanism 300 includes a flipping shaft 310 and a clamping assembly 320 installed on the flipping shaft 310; the clamping assembly 320 includes a mounting plate 321, a first clamping plate 322 and a second clamping plate 323; the mounting plate 321 is installed on the flipping shaft 310, the first clamping plate 322 and the second clamping plate 323 are arranged opposite to each other along the axial direction of the flipping shaft 310 and connected to the mounting plate 321, and the first clamping plate 322 and the second clamping plate 323 can be close to or away from each other, so that the first clamping plate 322 and the second clamping plate 323 abut and clamp the object to be detected. The flip shaft 310 can drive the clamping assembly 320 to rotate around its own rotation axis so that the object to be detected flips from the first preset position 130 to the second preset position 140. The detection mechanism is used to perform defect detection on the surface to be detected of the object to be detected in the second preset position 140. The support mechanism 400 includes a vertical support plate 410, a horizontal support plate 420, a first adjustment assembly 430 and a second adjustment assembly 440; the vertical support plate 410 is connected to the horizontal support plate 420, and the side of the horizontal support plate 420 away from the vertical support plate 410 is used to support the object to be detected. The first adjustment assembly 430 is installed on the horizontal support plate 420, and the first adjustment assembly 430 is configured with a accommodating space, and the accommodating space is used to accommodate and clamp the object to be detected. The second adjustment assembly 440 is slidably connected to the vertical support plate 410, and the second adjustment assembly 440 is used to adjust the height of the horizontal support plate 420 relative to the ground. Specifically, the height of the horizontal support plate 420 relative to the ground is the height in the zz' direction in Figure 1.

[0088] When the defect detection device provided by this embodiment performs defect detection on the battery shell 500, the conveying mechanism 100 is used to convey the battery shell 500. When the conveying mechanism 100 conveys the battery shell 500 to the first preset position 130, the identification mechanism 200 can identify the battery shell 500 at the first preset position 130. When the identification mechanism 200 identifies that there is a battery shell 500 at the first preset position 130, the flipping mechanism 300 can clamp the battery shell 500 at the first preset position 130 through the first clamping plate 322 and the second clamping plate 323, and rotate around its own rotation axis through the flip shaft 310, thereby driving the battery shell 500 to flip to the second preset position 140. At this time, the detection mechanism performs defect detection on the surface to be detected of the battery shell 500 at the second preset position 140. Since the battery housing 500 is directly flipped by the flipping mechanism 300 during the detection process, the battery housing 500 reduces the extra moving process during the detection process, reduces the cycle time, and takes less time for the detection process, thereby making the detection efficiency higher and the detection cost lower.

[0089] At the same time, because the first adjustment component 430 can adjust the size of the accommodating space, when the support mechanism 400 supports the battery housing 500 at the second preset position 140, the position of the battery housing 500 at the second preset position 140 is kept at a high precision, and it is not easy to shake or flip, etc., so that the detection mechanism has a better photo effect and higher detection accuracy when performing visual photo detection. In addition, the second adjustment component 440 can adjust the height of the horizontal support plate 420 relative to the ground, so that the support mechanism 400 can be adaptively raised and lowered according to the battery housings 500 of different heights, and can better adapt to the detection requirements of battery housings 500 of different heights, so that the adaptability of the defect detection device is higher.
