Description

Technical Field

[0001] This invention relates to the field of battery testing technology, specifically to a battery bulging detection device. Background Technology

[0002] The new energy vehicle industry is developing rapidly, and pouch lithium batteries are an important component of new energy vehicles. Therefore, the testing of pouch lithium batteries is essential. Currently, the main aspects to be tested include whether the surface of the pouch lithium battery has bulges or dents, scratches or wrinkles, etc., to strictly prevent pouch lithium batteries with quality problems from being put into use. At present, the main method is to place the batteries to be tested on a conveyor belt, and then use an industrial CCD camera to take pictures of the surface of the battery for testing. The captured images are converted into digital signals to complete the battery testing. However, the current battery testing process has the following problems: 1. Due to the large number of batteries to be tested, the batteries are arranged haphazardly when placed on the conveyor belt, and some batteries are squeezed together, resulting in poor imaging effect of the subsequent CCD camera, thus affecting the overall testing effect.

[0003] 2. When the battery is transported on the conveyor belt, the industrial CCD camera can only take pictures of the battery and the side opposite it. Therefore, when there are small bulges, dents or scratches on the two end faces of the battery, the CCD camera can only detect the upper surface of the battery when it is transported on the conveyor belt, and the lower surface of the battery is not detected. Summary of the Invention

[0004] Therefore, it is necessary to provide a battery bulge detection device to solve the problem of poor detection effect of bulges, dents and scratches on the two surfaces of the battery in the prior art.

Rotating sleeves are rotatably mounted on both the front and rear ends of the mounting plate. A threaded shaft is threadedly mounted inside each rotating sleeve and fixedly connected to a corresponding finishing plate. A first sprocket is fixedly mounted on each rotating sleeve. The number of teeth on the first sprocket closest to the fixed plate in the drive units is twice the number of teeth on the other first sprockets. A second sprocket corresponding to each first sprocket is fixedly mounted on the rotating shaft, and the first and corresponding second sprockets are connected by a chain.

[0013] According to an advantageous embodiment, the adjustment unit includes a slider groove, and the right end face of the fixed plate is provided with a slider groove running from top to bottom. An electric slider is slidably disposed in the slider groove, and two electric sliders are fixedly disposed together with a barrier plate.

The guide plate has an arc-shaped structure and the outer arc surfaces of the two guide plates are opposite to each other.

[0015] According to an advantageous embodiment, the flanging mechanism includes a horizontal plate, and a horizontal plate is fixedly provided on the opposite surfaces of the two vertical plates. A left swing plate and a right swing plate are hinged to the upper end surface of the horizontal plate. A pneumatic push rod connected to the right swing plate is hinged to the horizontal plate. The left swing plate and the right swing plate are rotatably connected to an L-shaped plate through a rotating column. The lower end surface of the left side of the L-shaped plate is in close contact with the conveyor belt.

[0017] According to an advantageous embodiment, the left end face of the upper part of the L-shaped area of ​​the L-shaped plate is provided with multiple sets of grooves arranged at equal distances from front to back, and each groove set contains multiple vertical grooves arranged at equal distances from front to back.

[0018] In summary, the present invention has at least one of the following beneficial effects: First, by reducing the distance between two adjacent sorting plates on different mounting plates and the distance between the fixing plate and the adjacent sorting plate, the batteries are sorted, which makes it easier for the CCD camera to detect and photograph the batteries in the future. The batteries are neatly arranged on the conveyor belt, thereby ensuring the detection effect of the batteries after the image is taken.

[0019] In this invention, the left and right swing plates work together to flip the L-shaped plate, allowing the battery to be flipped. Then, the CCD camera on the right side can detect the upper surface of the battery after it has been flipped, thus ensuring that both surfaces of the battery can be detected. This guarantees the overall detection effect of the battery and prevents batteries with quality problems from being used without being detected, which could lead to safety issues.

[0020] The infrared sensor in this invention controls the lifting and lowering of the electric slider and the barrier plate, thereby ensuring that the batteries in the same row can move neatly to the conveyor belt above the support plate, resulting in better imaging effect of the CCD camera and facilitating detection.

[0021] The vertical groove in this invention guides the battery and reduces the friction between the battery and the L-shaped plate, allowing the battery on the L-shaped plate to slide down onto the conveyor belt while maintaining its original posture, making it easier for the CCD camera on the right to take pictures and detect it.

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1 and Figure 2 As shown, a battery bulge detection device includes: a vertical plate 1, with two vertical plates 1 placed opposite each other.

[0044] The conveying assembly 2 is provided between the two vertical plates 1 for transmitting batteries. The conveying assembly 2 includes a conveyor belt 20, belt rollers 21 and support assemblies 22. The two vertical plates 1 are symmetrically arranged with left and right belt rollers 21 rotatably connected to an external motor via a rotating shaft. The two belt rollers 21 are connected and cooperated with each other through the conveyor belt 20. The two support assemblies 22 are both arranged between the two belt rollers 21.

[0045] The organizing mechanism 3 is provided between the left sides of the two vertical plates 1 for organizing the battery position.

[0046] The flanging mechanism 4 is provided between the two vertical plates 1 for flanging the battery, and the two support components 22 are both provided between the two belt rollers 21.

[0047] A suspension plate 5 is fixedly provided between the two vertical plates 1 for mounting a CCD camera, and the positions of the suspension plate 5 and the support plate 222 correspond one-to-one.

[0048] like Figure 2 and Figure 3 As shown, the support assembly 22 includes a support shaft 220. Two support shafts 220 are rotatably arranged between the two vertical plates 1. Fixed rollers 221 that are in close contact with the conveyor belt 20 are fixedly sleeved on the support shafts 220. A support plate 222 that is in close contact with the lower end face of the upper part of the conveyor belt 20 is fixedly arranged between the two vertical plates 1. The support plate 222 is located between two corresponding fixed rollers 221. Two symmetrical vertical blocks 223 are fixedly arranged on the upper end face of the support plate 222. Multiple pressure rollers 224 arranged at equal distances from left to right are rotatably arranged on the opposite faces of the two vertical blocks 223 through a connecting shaft. The pressure rollers 224 are in close contact with the conveyor belt 20 on the support plate 222.

[0049] During operation, the batteries to be tested are first placed manually on the left side of the conveyor belt 20. Then, an external motor starts moving the conveyor belt 20 via the belt roller 21, transporting the batteries from left to right. The batteries are first sorted by the sorting mechanism 3, ensuring they are evenly distributed on the conveyor belt 20. When the batteries move to the first support assembly 22, the pressure roller 224 and support plate 222 work together. The support plate 222 supports the conveyor belt 20, while the pressure roller 224 flattens it, keeping the conveyor belt 20 horizontal for subsequent CCD camera inspection. The CCD camera then takes an image of the battery located above the support. The battery then moves to the flanging mechanism 4 and is flanged. Simultaneously, when the battery moves to the second support assembly 22, the external CCD camera on the right takes an image of the battery directly opposite it. Finally, the tested batteries are collected manually on the right side of the conveyor belt 20, completing the battery testing process.

[0050] like Figure 4 , Figure 5 and Figure 6 As shown, the sorting mechanism 3 includes a placement plate 30, which is fixedly disposed between two vertical plates 1. The lower end face of the placement plate 30 is fixedly disposed with two front-to-back fixed plates 300 and multiple T-shaped plates 31 arranged at equal distances from front to back. All T-shaped plates 31 are located between two fixed plates 300. The front part of the T-shaped plate 31 is fixedly disposed with a triangular plate 32 for guiding the battery by a connecting strip. The front and rear end faces of the T-shaped plate 31 are provided with rod grooves. The sorting plate 33 is slidably disposed in the rod grooves by a connecting rod. A drive unit 34 for moving the sorting plate 33 is disposed between the two fixed plates 300. An adjustment unit 35 is fixedly disposed on the right end face of the two fixed plates 300.

[0051] like Figure 5As shown, the drive unit 34 includes a rotating shaft 340. The rotating shaft 340 is rotatably mounted between the two fixed plates 300, and the rotating shaft 340 is connected to an external motor. Multiple drive groups, the same number as the T-shaped plates 31, are equidistantly distributed on the rotating shaft 340. Each drive group includes a mounting plate 341. A mounting plate 341 corresponding to each drive group is fixedly mounted on the lower end face of the placement plate 30. Rotating sleeves 342 are rotatably mounted on both the front and rear end faces of the mounting plate 341. The rotating sleeves 342 are threaded... A threaded shaft 343 is provided and fixedly connected to the corresponding sorting plate 33. A first sprocket 344 is fixedly mounted on each rotating sleeve 342. The number of teeth of the first sprocket 344 closest to the fixed plate 300 in the drive unit 34 is twice the number of teeth of the other first sprockets 344. A second sprocket 345 corresponding to the first sprocket 344 is fixedly mounted on the rotating shaft 340. The first sprocket 344 and the corresponding second sprocket 345 are connected to each other by a chain.

[0052] like Figure 4 and Figure 5 As shown, the adjustment unit 35 includes a slider groove 350. The right end face of the fixed plate 300 has a slider groove 350 extending from top to bottom. An electric slider is slidably disposed in the slider groove 350. Two electric sliders are fixedly disposed together with a barrier plate 351. The right end face of the barrier plate 351 is provided with a plurality of infrared sensors 352 arranged at equal intervals for sensing whether the left side of the barrier plate 351 is in close contact with the battery. The infrared sensors 352 transmit signals to an external receiver for controlling the electric sliders.

[0053] like Figure 4 , Figure 5 and Figure 6 As shown, the front end face of the sorting plate 33 is hinged with an arc plate 36, and the inner arc surface of the arc plate 36 is opposite to the corresponding triangular plate 32. A first spring 360 is fixedly arranged between the arc plate 36 and the left side of the T-shaped plate 31. A guide plate 361 is fixedly arranged on the left end face of the fixing plate 300. The guide plate 361 has an arc structure and the outer arc surfaces of the two guide plates 361 are opposite to each other.

[0054] During operation, the external motor 2 first drives the rotating shaft 340 to rotate. The rotating shaft 340 drives all the second sprockets 345 to rotate synchronously. The first sprocket 344 is connected to the second sprocket 345 through the corresponding chain. Therefore, the first sprocket 344 drives the corresponding rotating sleeve 342 to rotate synchronously with the rotating shaft 340. The rotating sleeve 342 is threadedly connected to the corresponding threaded shaft 343. The two threaded shafts 343 on the same mounting plate 341 have opposite helical directions. Therefore, the threaded shafts 343 on the same mounting plate 341 drive the corresponding sorting plate 33 away from the corresponding mounting plate 341. As a result, the distance between two adjacent sorting plates 33 on different mounting plates 341 and the distance between the fixed plate 300 and the adjacent sorting plate 33 are reduced to the specified distance.

[0055] Afterwards, when the batteries to be tested are placed manually on the left side of the conveyor belt 20, the guide plate 361 first guides the batteries so that they can move into the sorting mechanism 3. Then, the batteries first come into contact with the triangular plate 32. The triangular plate 32 diverts and guides the placed batteries, so that the batteries move between the fixed plate 300 and the sorting plate 33 or between the two sorting plates 33, that is, the passing batteries are sorted so that when the CCD camera tests and takes pictures of the batteries, the batteries are neatly arranged on the conveyor belt 20.

[0056] The number of teeth on the first sprocket 344 closest to the fixed plate 300 is twice that of the other first sprockets 344. This ensures that the distance the adjacent sorting plates 33 on the fixed plate 300 move is twice that of the other fixed plates 300, guaranteeing that the distance between two adjacent sorting plates 33 on different mounting plates 341 and the distance between the fixed plate 300 and its adjacent sorting plates 33 are the same. This facilitates the sorting of batteries while preventing excessive pressure from adjacent sorting plates 33, which could damage or cause spontaneous combustion. It also allows for the sorting of batteries of different sizes. During this process, the electric slider moves the barrier plate 351 downwards to block the battery. When the infrared sensor 352 detects the channel between the fixed plate 300 and its adjacent sorting plate 33 on the left side of the barrier plate 351, and the distance between the fixed plate 300 and its adjacent sorting plate 33, and the distance between the fixed plate 300 and its adjacent sorting plate 33, the infrared sensor detects the battery. Each of the two adjacent sorting plates 33 on the mounting plate 341 contains a battery. After being sorted, the batteries are all in contact with the barrier plate 351, forming a row from front to back with all batteries in close contact with the barrier plate 351. Then, the infrared sensor 352 transmits a signal to an external receiver. The receiver controls the electric slider to raise the barrier plate 351, allowing the batteries to move to the right side of the barrier plate 351. The infrared sensor 352 then detects that there are no batteries in contact with the left side of the barrier plate 351, so it transmits a signal to the external receiver. The external receiver then controls the barrier plate 351 to move down quickly via the electric slider to continue blocking subsequent batteries. This ensures that the same row of batteries can move neatly to the conveyor belt 20 above the support plate 222, resulting in better imaging performance by the CCD camera.

[0057] The arc-shaped plate 36 is kept in close contact with the corresponding triangular plate 32 under the elastic force generated by the deformation of the corresponding first spring 360. Therefore, during the movement of the sorting plate 33, the triangular plate 32 is kept in a shunt and guide function for the placed battery.

[0058] like Figure 7 and Figure 8As shown, the flanging mechanism 4 includes a horizontal plate 40. The two vertical plates 1 are fixedly provided with horizontal plates 40 on their opposite sides. The upper end of the horizontal plate 40 is hinged with a left swing plate 41 and a right swing plate 42. A pneumatic push rod connected to the right swing plate 42 is hinged on the horizontal plate 40. The left swing plate 41 and the right swing plate 42 are rotatably connected to an L-shaped plate 43 through a rotating column. The lower end of the left side of the L-shaped plate 43 is in close contact with the conveyor belt 20. Two front-to-back symmetrical triangular baffles 44 and multiple triangular blocks 45 arranged at equal distances from front to back are fixedly provided in the L-shaped area of ​​the L-shaped plate 43. All blocks 45 are located between two baffles 44. An auxiliary unit 46 for assisting in controlling the position of the battery on the L-shaped plate 43 is provided on the inclined surface of the blocks 45. The opposite sides of the two vertical plates 1 are rotatably provided with two left-to-right distributed pressure rollers 47 through a connecting shaft.

[0059] like Figure 7 and Figure 8 As shown, the auxiliary unit 46 includes a block shifting groove 460. The inclined surface of the stop block 45 has two block shifting grooves 460 from front to back. An electric slider 2 is slidably arranged in the block shifting groove 460. A rectangular strip 461 is fixedly arranged on the electric slider 2. A seven-shaped auxiliary plate 462 is fixedly arranged on the end face of the rectangular strip 461 away from the corresponding stop block 45.

[0060] After the battery moves into the first support assembly 22 and is photographed and imaged by the CCD camera above the support plate 222, the conveyor belt 20 transports the battery into the L-shaped plate 43. Then, the electric slider 2 operates, causing the rectangular bar 461 to move the corresponding auxiliary plate 462 closer to the adjacent battery. Thus, the two adjacent auxiliary plates 462 located on different stops 45 securely clamp the battery, facilitating subsequent flanging operations. Then, the pneumatic push rod operates, causing the right swing plate 42 to swing, thereby causing the L-shaped plate 43 to swing to the right and rotate. Ultimately, the L-shaped area of ​​the L-shaped plate 43 faces to the right, and the right end face of the upper part of the L-shaped plate 43 moves and comes into close contact with the conveyor belt 20. Afterwards, the electric slider 2 operates... The rectangular bar 461 causes the auxiliary plate 462 to stop clamping the battery. At this time, the auxiliary plate 462 is in contact with the battery but there is no force between them. Then, the battery slides out of the L-shaped plate 43 and back onto the conveyor belt 20 under its own weight. Thus, the flanging mechanism 4 completes the flanging operation of the battery and resets. Then, it moves into the second support component 22 and the CCD camera takes a picture of the battery located above the support plate 222 for detection. Therefore, the flanging mechanism 4 can flanging the battery to ensure that both the front and back of the battery can be detected, thus ensuring the detection effect. In addition, the pressure roller 47 is in close contact with the upper end of the conveyor belt 20, so that the part of the conveyor belt 20 located in the flanging mechanism 4 remains horizontal, which makes it easy for the battery to slide into or out of the L-shaped plate 43.

[0061] like Figure 8 As shown, the upper left end face of the L-shaped area of ​​the L-shaped plate 43 has multiple sets of grooves arranged at equal distances from front to back, and each groove set contains multiple vertical grooves 48 arranged at equal distances from front to back.

[0062] During operation, after the auxiliary plate 462 contacts the battery but there is no force between them, the battery slides down the L-shaped plate 43 and back onto the conveyor belt 20 under its own weight. During this process, the contact area between the upper left end face of the L-shaped plate 43 and the battery is reduced, which facilitates the battery's descent. The vertical groove 48 guides the battery, allowing it to maintain its original posture as it slides down onto the conveyor belt 20, making it easier for the CCD camera on the right to take pictures and detect it.

[0063] In practice, the battery to be tested is first placed manually on the left side of the conveyor belt 20. Then, an external motor 1 operates, causing the conveyor belt 20 to move via the belt roller 21, which in turn moves the battery. The triangular plate 32 in the sorting mechanism 3 then guides the battery by diverting its flow. Simultaneously, an external motor 2 operates, driving the rotating shaft 340 to rotate. Through the cooperation between the first sprocket 344 and the second sprocket 345, the first sprocket 344 drives the corresponding rotating sleeve 342 to rotate synchronously with the rotating shaft 340. This causes the threaded shaft 343 on the same mounting plate 341 to move the corresponding sorting plate 33 away from the corresponding mounting plate 341, thus allowing different mounting plates 341 to move away from the corresponding mounting plate 341. The distance between two adjacent sorting plates 33 on 41 and the distance between the fixed plate 300 and the adjacent sorting plate 33 are reduced, thereby sorting the batteries that pass through. At the same time, the adjustment unit 35 adjusts the position of the batteries in the left and right directions so that the batteries in this row can be arranged neatly. Then, the external CCD camera on the left takes a picture of the battery for detection. The battery moves to the flipping mechanism 4 and the battery flips. Then, when the battery moves to the second support component 22, the external CCD camera on the right takes a picture of the other side of the battery for detection. After that, the battery that has been detected is collected manually on the right side of the conveyor belt 20.
