Description

Technical Field

[0001] This invention relates to the field of lithium battery processing technology for new energy vehicles, and in particular to an integrated equipment for feeding, conveying and inspecting batteries. Background Technology

[0002] With the advancement of battery technology, especially the development of lithium batteries in new energy vehicles towards larger sizes and higher energy densities, traditional conveying devices can no longer meet the demands for efficient and precise production. Battery production mainly relies on automated production lines to achieve large-scale production through processes such as winding and packaging.

[0003] After the battery is manufactured, it needs to undergo a series of inspections to be considered qualified.

[0004] Existing technologies mostly consist of splicing together decentralized equipment for feeding, conveying, inspection, and unloading, or simple integrated designs; the feeding, conveying, inspection, and unloading cycles are mismatched, resulting in frequent waiting times; sorting of defective products requires manual intervention, making it impossible to achieve full-process automation; they cannot meet the efficiency requirements of large-scale battery production, nor can they guarantee the quality requirements of high-precision inspection, and the equipment has poor versatility and stability, resulting in high operation and maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device for feeding, conveying, and inspecting batteries, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An integrated device for feeding, conveying, and inspecting batteries includes a battery feeding mechanism, a pallet conveying mechanism, and a battery inspection mechanism arranged along the length of the pallet conveying mechanism.

[0007] The pallet conveying mechanism includes a battery conveying frame and a battery conveyor belt arranged along the length of the battery conveying frame. The battery conveyor belt is arranged with multiple sets of locking blocks at equal intervals along its length. Each set of locking blocks is engaged with a battery pallet for positioning the battery. The battery pallet is formed with a guide slot, and a portion of the guide roller is exposed downwards in the guide slot. A concave guide annular groove is formed around the outer circumference of the guide roller. A linear guide shaft is installed along the length of the battery conveying frame, and the linear guide shaft and the guide roller are in rolling cooperation. The battery inspection mechanism includes a first inspection module and a second inspection module. The first and second inspection modules each include a first inspection seat located on the left side of the battery conveyor and a second inspection seat located on the right side of the battery conveyor. The first inspection seat is equipped with a first light-collecting plate and a first light generator facing the battery tray. The second inspection seat is equipped with a second light-collecting plate and a second light generator facing the battery tray. The first light-collecting plate and the second light generator are coaxially aligned, and the second light-collecting plate and the first light generator are also coaxially aligned. The first light-collecting plate and the second light generator are coaxially aligned along one diagonal of the battery tray, and the first light-collecting plate and the second light generator are coaxially aligned along the other diagonal of the battery tray. The first inspection module and the second inspection module are also respectively provided with a tray lifting mechanism. The tray lifting mechanism includes a lifting platform installed on the battery conveying rack. A rotating platform capable of lateral rotation is installed on the top of the lifting platform. The rotating platform is equipped with a locking structure for positioning the battery tray. The rotating platform lifts and supports the battery tray.

[0008] Furthermore: The battery loading mechanism is provided at one end of the pallet conveying mechanism, and the battery unloading mechanism is provided at the other end. The battery loading mechanism and the battery unloading mechanism each include a transfer gantry frame arranged horizontally and perpendicularly to the pallet conveying mechanism. One end of the transfer gantry frame is located above the pallet conveying mechanism. A transfer drive frame is slidably installed on the transfer gantry frame. A gripping frame capable of lifting and lowering is installed on the transfer drive frame. The gripping frame is equipped with two clamping modules. The distance between the two clamping modules is exactly equal to the distance between the two sets of locking blocks. The clamping module includes a pair of clamping arms capable of opening and closing. A clamping structure that cooperates with the battery pallet is provided at the bottom of the clamping arms.

[0009] Furthermore: a horizontally arranged sliding frame and a transfer telescopic cylinder that drives the sliding frame to move are installed at the bottom of the gripping frame. The drive end of the transfer telescopic cylinder is connected to the sliding frame. The clamping arm is installed vertically at the bottom of the sliding frame. The clamping arm is equipped with a vertical drive bar for lifting and moving. A horizontally arranged insertion bar is installed at the bottom of the vertical drive bar. The battery tray is equipped with an insertion seat. The insertion seat is formed with an insertion groove for the horizontal insertion of the insertion bar.

[0010] Furthermore: The bottom of the gripping frame is equipped with a linear track for guiding the sliding frame to slide. The sliding frame is formed with a laterally concave guide groove. The guide groove is laterally aligned with the transfer telescopic cylinder. The cylinder body of the transfer telescopic cylinder is equipped with a transfer inspection seat that can extend and retract longitudinally. The transfer inspection seat is equipped with a downwardly extending elastic probe. The elastic probe is vertically coaxially aligned with the battery tabs of the battery tray.

[0011] Furthermore: the battery conveyor frame includes a pair of parallel and spaced-apart conveyor guide side plates, and two battery conveyor belts arranged at intervals. The two battery conveyor belts provide positioning support for the battery tray, and the distance between the two battery conveyor belts allows the rotating platform of the tray lifting mechanism to move up and down. The tray conveying mechanism also includes synchronous wheels installed at both ends of the battery conveyor frame, with the battery conveyor belts sleeved between the two synchronous wheels. A wheel support seat parallel to the conveyor guide side plates is installed inside the synchronous wheel, and the wheel support seat is connected to the conveyor guide side plates. A wheel mounting shaft for installing the synchronous wheels is connected between the wheel support seat and the conveyor guide side plates.

[0012] Furthermore: a protective guide plate is arranged along the length of the bottom of the conveyor guide side plate. The protective guide plate has a U-shaped cross-section. There is a gap between the protective guide plate and the bottom of the conveyor guide side plate for the battery conveyor belt to pass through. The protective guide plate surrounds and supports the battery conveyor belt. The linear guide shaft is installed on the top of the wheel support seat. Multiple guide shaft support seats for supporting the linear guide shaft are installed along the conveyor guide side plate. The guide shaft support seats are formed with guide passage holes that are coaxially aligned with the linear guide shaft.

[0013] Furthermore: the first inspection seat and the second inspection seat are respectively equipped with two sets of inspection drive seats and adjustment drive modules that drive the inspection drive seats to adjust in the X, Y, Z, and R axis directions. The adjustment drive module includes a first linear module arranged laterally perpendicular to the moving direction of the battery tray. A first linear guide rail is installed next to the first linear module. A first linear slide seat is slidably installed on the first linear guide rail. A second linear module is installed at the drive end of the first linear module. One end of the second linear module is connected to the first linear slide seat. The second linear module is arranged laterally perpendicular to the first linear module. A longitudinal drive frame is installed at the drive end of the second linear module. A third linear module is arranged longitudinally on the longitudinal drive frame. A lifting drive platform is installed at the drive end of the third linear module. An inspection fixing platform is installed on the lifting drive platform. A top rotating platform that can rotate laterally is installed on the inspection fixing platform. The inspection drive seat is installed on the top rotating platform.

[0014] Furthermore: the first light-collecting plate and the first light generator of the first inspection seat are respectively installed on the corresponding inspection drive seat; the second light-collecting plate and the second light generator of the second inspection seat are respectively installed on the corresponding inspection drive seat; the first light generator and the second light generator are both light-emitting elements that irradiate light along the tangential direction of the battery surface, and the first light-collecting plate and the second light-collecting plate are photosensitive elements that collect the light after the object under test acts on them.

[0015] Furthermore, the pallet lifting mechanism also includes a support column installed at the bottom of the battery conveying rack. The support column has a vertical linear module arranged along its length. A lifting platform is installed at the drive end of the vertical linear module. The lifting platform is equipped with a DD motor. The drive end of the DD motor is connected to the rotating table. The locking structure includes a pair of spaced locking blocks. The top of the locking blocks is formed with an flared structure for guiding and embedding the battery pallet.

[0016] The beneficial effects of this invention are as follows: Battery trays loaded with batteries are fed from the battery loading mechanism to the tray conveying mechanism. Equidistant locking blocks on the battery conveyor belt directly engage the battery trays. This ensures that multiple battery trays maintain a fixed spacing along the length of the conveyor belt, facilitating synchronized operation of the subsequent lifting and inspection mechanisms at fixed intervals, thus improving the overall process continuity. Furthermore, the locking blocks restrict the trays' movement in the conveying direction, preventing collisions or misalignment and protecting the batteries from handling damage. Subsequently, the battery trays move forward via the battery conveyor belt. Guide rollers at the bottom of the battery trays engage with the linear guide shaft of the battery conveyor frame through concave guide annular grooves. These grooves partially enclose the linear guide shaft, strictly limiting lateral displacement of the battery trays and ensuring they are always conveyed in a straight line. This keeps the battery position within the tray stable, and the rolling engagement significantly reduces the coefficient of friction, minimizing equipment wear and extending service life.

[0017] The battery trays then pass through a battery inspection facility. Some of the battery trays undergo visual inspection by the first inspection module, while others undergo visual inspection by the second inspection module. This increases inspection efficiency and prevents battery trays from accumulating in the battery inspection facility.

[0018] When inspecting the battery body in the battery tray, the first light-receiving plate and the second light generator are coaxially aligned with the first diagonal of the battery tray, and the second light-receiving plate and the first light generator are coaxially aligned with the second diagonal, forming a cross-diagonal inspection light path. This light path can fully cover the planar position and appearance integrity of the battery. If the battery is offset in the tray, such as not being placed upright, having damage or missing corners, or having no battery in the tray, it will directly block one or two diagonal light paths, causing abnormal light signals received by the light-receiving plate, thus accurately identifying and addressing issues such as positioning deviations, appearance defects, and missing batteries.

[0019] After the inspection of two corners facing the first and second light generators is completed, the pallet lifting mechanism operates, lifting the battery pallet from the conveyor belt. Then, the rotating platform rotates 180°, allowing the remaining two corners facing the first and second light generators to undergo a second inspection. This ensures that all four corners of the battery are inspected thoroughly, providing extensive inspection coverage. The fully automated operation avoids battery bumps and scratches caused by manual handling, reducing the battery scrap rate. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, an integrated equipment for feeding, conveying and inspecting batteries includes a battery feeding mechanism 1, a pallet conveying mechanism 3 and a battery inspection mechanism 5 arranged along the length of the pallet conveying mechanism 3.

[0029] The pallet conveying mechanism 3 includes a battery conveying frame 31 and a battery conveying belt 33 arranged along the length of the battery conveying frame 31. The battery conveying belt 33 is arranged with multiple sets of locking blocks 38 at equal intervals along the length. Each set of locking blocks 38 is engaged with a battery pallet 4 for positioning the battery. The battery pallet 4 is formed with a guide slot 41. A roller mounting seat 42 is installed in the guide slot 41. A guide roller 43 is partially exposed at the bottom of the roller mounting seat 42. A concave guide annular groove 44 is formed around the outer circumference of the guide roller 43. A linear guide shaft 45 is installed in the length of the battery conveying frame 31. The linear guide shaft 45 and the guide roller 43 are in rolling cooperation. The battery inspection mechanism 5 includes a first inspection module 51 and a second inspection module 52. The first inspection module 51 and the second inspection module 52 respectively include a first inspection seat 53 disposed on the left side of the battery conveyor 31 and a second inspection seat 54 disposed on the right side of the battery conveyor 31. The first inspection seat 53 is equipped with a first light-collecting plate 55 and a first light generator 56 facing the battery tray 4. The second inspection seat 54 is equipped with a second light-collecting plate 57 and a second light generator 58 facing the battery tray 4. The first light-collecting plate 55 and the second light generator 58 are coaxially aligned, and the second light-collecting plate 57 and the first light generator 56 are coaxially aligned. The first light-collecting plate 55 and the second light generator 58 are coaxially aligned along one diagonal of the battery tray 4, and the first light-collecting plate 55 and the second light generator 58 are coaxially aligned along the other diagonal of the battery tray 4.

[0030] The first inspection module 51 and the second inspection module 52 are also respectively provided with a tray lifting mechanism 7. The tray lifting mechanism 7 includes a lifting platform 73 installed on the battery conveying rack 31. A rotating platform 75 capable of lateral rotation is installed on the top of the lifting platform 73. The rotating platform 75 is equipped with a locking structure 76 for positioning the battery tray 4. The rotating platform 75 lifts and supports the battery tray 4.

[0031] Battery trays 4, loaded with batteries, are fed from battery loading mechanism 1 to tray conveying mechanism 3. Equally spaced locking blocks 38 on the battery conveyor belt 33 directly engage with the battery trays 4. This ensures that multiple battery trays 4 maintain a fixed spacing along the length of the conveyor belt, facilitating synchronized operation of subsequent lifting and inspection mechanisms at fixed intervals, thus improving overall process continuity. Furthermore, the locking blocks 38 restrict the trays' movement in the conveying direction, preventing collisions or misalignment and protecting the batteries from handling damage. Subsequently, the battery trays 4 move forward via the battery conveyor belt 33. Guide rollers 43 at the bottom of the battery tray 4 engage with the linear guide shaft 45 of the battery conveyor frame 31 through a concave guide annular groove 44. The concave annular groove partially encloses the linear guide shaft 45, strictly limiting lateral displacement of the battery trays 4 and ensuring they are always conveyed in a straight line. This stabilizes the position of the batteries within the tray, and the rolling engagement significantly reduces the coefficient of friction, minimizing equipment wear and extending service life.

[0032] The battery tray 4 then passes through the battery inspection mechanism 5. A portion of the battery trays 4 undergoes visual inspection by the first inspection module 51, while a portion undergoes visual inspection by the second inspection module 52, thereby increasing inspection efficiency and preventing the battery trays 4 from accumulating in the battery inspection mechanism 5.

[0033] When inspecting the battery body in the battery tray 4, the first light-receiving plate 55 and the second light generator 58 are coaxially aligned with the first diagonal of the battery tray 4, and the second light-receiving plate 57 and the first light generator 56 are coaxially aligned with the second diagonal, forming a cross-diagonal inspection light path. This light path can fully cover the planar position and appearance integrity of the battery. If the battery is offset in the tray, such as not being placed upright, having damage or missing corners, or having no battery in the tray, it will directly block one or two diagonal light paths, causing abnormal light signals received by the light-receiving plate, thus accurately identifying, positioning deviations, appearance defects, missing batteries, and other problems.

[0034] After the inspection of two corners facing the first light generator 56 and the second light generator 58 is completed, the pallet lifting mechanism 7 operates, and the lifting platform 73 lifts the battery pallet 4 from the conveyor belt. Then, the rotating platform 75 rotates 180° so that the remaining two corners facing the first light generator 56 and the second light generator 58 can be inspected a second time. This ensures that the appearance of all four corners of the battery is inspected thoroughly, providing a very wide inspection coverage. The fully automated operation avoids battery bumps and scratches caused by manual handling, reducing the battery scrap rate.

[0035] A battery loading mechanism 1 is located at one end of a pallet conveying mechanism 3, and a battery unloading mechanism 10 is located at the other end of the pallet conveying mechanism 3. Both the battery loading mechanism 1 and the battery unloading mechanism 10 include a transfer gantry 11 arranged laterally and perpendicular to the pallet conveying mechanism 3. One end of the transfer gantry 11 is located above the pallet conveying mechanism 3. A transfer drive frame 12 is slidably mounted on the transfer gantry 11. A linear module and a linear track parallel to the linear module are arranged along the length of the transfer gantry 11 to ensure that the transfer drive frame 12 moves perpendicularly to the pallet conveying mechanism 3. A lifting gripper 13 is mounted on the longitudinally arranged linear module of the transfer drive frame 12. The gripper 13 can move up and down under the drive of the linear module. The gripping frame 13 is equipped with two clamping modules 14. The distance between the two clamping modules 14 is exactly equal to the distance between the two sets of positioning blocks 38. The two clamping modules 14 clamp the two battery trays 4 simultaneously, which can synchronously place the two battery trays 4 onto the two sets of positioning blocks 38 of the tray conveying mechanism 3. The distance between the two battery trays 4 is exactly the same as the distance between the positioning blocks 38, and they fall into place at the same time, avoiding the displacement of the positioning blocks 38 due to uneven force when a single battery tray 4 falls into place. After the battery trays 4 are accurately inserted into the positioning blocks 38, the two sets of battery trays 4 can move synchronously along the same trajectory when the battery conveyor belt 33 is running. The trays will not squeeze each other or fall off the positioning blocks 38 due to the distance deviation, which provides a basis for subsequent accurate conveying.

[0036] In addition, the sliding track of the transfer gantry 11 is strictly perpendicular to the length direction of the pallet conveying mechanism 3. When the transfer drive frame 12 slides along the track to the required position, it ensures that the grabbed battery pallet 4 is transferred above the conveying mechanism, and its center is precisely aligned with the center of the locking block 38 on the battery conveyor belt 33.

[0037] Furthermore, the clamping module 14 includes a pair of clamping arms 15 capable of opening and closing, with a clamping structure at the bottom of the clamping arms 15 that cooperates with the battery tray 4. The bottom of the gripping frame 13 is equipped with a laterally arranged sliding frame 2 and a transfer telescopic cylinder 23 that moves the sliding frame 2. The drive end of the transfer telescopic cylinder 23 is connected to the sliding frame 2. The clamping arms 15 are longitudinally mounted at the bottom of the sliding frame 2, and the clamping arms 15 are equipped with a vertically moving vertical drive bar 16. A laterally arranged insertion bar 17 is mounted at the bottom of the vertical drive bar 16. The battery tray 4 is equipped with an insertion seat 47, which has an insertion groove 48 for the laterally inserted insertion bar 17.

[0038] A pair of opening and closing clamping arms 15 can adaptively adjust their opening and closing range according to the tray size. The bottom clamping structure can wrap around and clamp the battery tray 4 from both sides laterally. That is, the longitudinal drive bar 16 drives the insertion bar 17 to descend and insert it laterally into the insertion slot 48 of the tray insertion seat 47 to form a locking clamp. During the transfer and lifting process, even if the gripping frame 13 vibrates slightly, the insertion bar 17 can prevent the battery tray 4 from jumping up and down or falling off because it is locked in the insertion slot 48. If it is necessary to produce battery trays 4 of different sizes, the position of the sliding frame 2 can be adjusted by adjusting the position of the transfer telescopic cylinder 23 to change the spacing of the two clamping modules 14 to adapt to the spacing requirements of the new battery tray 4. At the same time, the opening and closing range of the clamping arms 15 can be adjusted synchronously. Without replacing the clamping module 14 or modifying the equipment, it is possible to realize the loading and unloading of batteries of various specifications, expand the applicable scenarios of the equipment, and reduce the equipment modification costs when enterprises change product lines.

[0039] Furthermore, the bottom of the gripping frame 13 is equipped with a bottom linear track 21 for guiding the sliding frame 2 to slide. The sliding frame 2 is formed with a laterally concave guide groove 22, which is laterally aligned with the transfer telescopic cylinder 23. When the sliding frame 2 clamps and positions the battery tray 4 laterally, the opening and closing action will not cause collision because the guide groove 22 is laterally aligned with the transfer telescopic cylinder 23, thus ensuring opening and closing stability. The cylinder body of the transfer telescopic cylinder 23 is equipped with an inspection telescopic cylinder 24, which drives the transfer inspection seat 25 to extend and retract longitudinally. The transfer inspection seat 25 is equipped with a downwardly extending elastic probe 26, which is vertically coaxially aligned with the battery tabs of the battery tray 4. When the gripping frame 13 drives the clamping module 14 to grip the battery tray 4, the drive end of the inspection telescopic cylinder 24 drives the transfer inspection seat 25 to extend and retract longitudinally, so that the elastic probe 26 extends downward and makes precise contact with the battery tabs in the tray; the battery tabs are inspected; if the tabs are present, the probe will be blocked and compressed by the tabs; if the tabs are missing or the battery is missing, the probe will continue to extend downward without obstruction until it touches the bottom of the tray.

[0040] A displacement sensor, such as a miniature linear potentiometer or a grating displacement sensor, is integrated inside the probe or on the transfer test holder 25. This sensor can acquire the compression displacement of the probe in real time, thereby outputting a corresponding test pulse signal. The elastic probe 26 is a conductive probe made of copper alloy. Furthermore, a miniature pressure sensor is integrated at the base of the probe to check the direction and magnitude of the force applied to the probe. If the pressure is only vertically downward, the tab position is normal; if a lateral component force is present, it is determined that the tab has a lateral offset, and the direction of the component force corresponds to the offset direction.

[0041] Specifically, the battery conveyor frame 31 includes a pair of parallel and spaced conveyor guide side plates 32, and two battery conveyor belts 33. The two battery conveyor belts 33 are arranged at intervals and support the battery tray 4. The double conveyor belts share the load, which can reduce the deformation of a single conveyor belt, extend the service life of the conveyor belt, and ensure that the tray is always conveyed in a horizontal direction.

[0042] The pallet conveying mechanism 3 also includes synchronous pulleys 34 installed at both ends of the battery conveying frame 31, with the battery conveyor belt 33 nested between the two synchronous pulleys 34. A wheel support seat 35, parallel to the conveyor guide side plate 32, is installed inside the synchronous pulley 34. The wheel support seat 35 is connected to the conveyor guide side plate 32, and a wheel mounting shaft 36 for mounting the synchronous pulley 34 is connected between the wheel support seat 35 and the conveyor guide side plate 32. This ensures that the linear speeds of the two battery conveyor belts 33 are completely consistent, and the force is evenly distributed on both sides of the bottom of the battery pallet 4. The wheel mounting shaft 36 adopts a detachable design, connected to the wheel support seat 35 via bearings, and fixed at both ends with nuts. When the synchronous pulley 34 or the battery conveyor belt 33 needs to be replaced, only the wheel mounting shaft 36 needs to be removed to remove the synchronous pulley 34, without disassembling the entire conveyor frame, reducing equipment downtime maintenance costs and improving production continuity.

[0043] The distance between the two battery conveyor belts 33 allows the rotating platform 75 of the pallet lifting mechanism 7 to move up and down without having to avoid the battery conveyor belts 33, greatly simplifying the operation logic of the lifting mechanism and reducing lifting time. After the lifting is completed, when the rotating platform 75 drives the battery pallet 4 to fall back, the battery pallet 4 can be directly placed back on the locking block 38 of the double conveyor belts, and the battery conveyor belts 33 will continue to transport immediately without any connection or waiting, saving time and improving efficiency.

[0044] Furthermore, a protective guide plate 37 is arranged along the length direction at the bottom of the conveyor guide side plate 32. The protective guide plate 37 has a U-shaped cross-section. There is a gap between the protective guide plate 37 and the bottom of the conveyor guide side plate 32 for the battery conveyor belt 33 to pass through. The protective guide plate 37 surrounds and supports the battery conveyor belt 33. The protective guide plate 37 covers the bottom of the battery conveyor belt 33, which can prevent dust and debris from the workshop floor from entering the meshing area between the battery conveyor belt 33 and the synchronous pulley 34. The two vertical sides of the U-shaped protective plate form a small gap with the side of the battery conveyor belt 33, which can limit the lateral deviation of the battery conveyor belt 33 during operation, prevent the battery conveyor belt 33 from rubbing against the conveyor guide side plate 32 due to deviation, and at the same time prevent the conveyor belt from falling off the synchronous pulley 34.

[0045] A linear guide shaft 45 is mounted on top of the wheel support 35. Multiple guide shaft support seats 46 are installed along the conveyor guide side plate 32 to support the linear guide shaft 45. Each guide shaft support seat 46 has a guide through hole coaxially aligned with the linear guide shaft 45. This ensures that the guide rollers 43 at the bottom of the battery tray 4 drive the battery tray 4 in a direction completely consistent with the conveyor belt's conveying direction, preventing the battery tray 4 from twisting. The multiple guide shaft support seats 46 disperse the force on the linear guide shaft 45, ensuring that the linear guide shaft 45 maintains its straightness even after long-term operation.

[0046] The first inspection seat 53 and the second inspection seat 54 are respectively equipped with two sets of inspection drive seats 60 and adjustment drive modules 6 that drive the inspection drive seats 60 to adjust in the X, Y, Z, and R axis directions. The adjustment drive module 6 includes a first linear module 61 arranged laterally perpendicular to the moving direction of the battery tray 4. A first linear guide rail 62 is installed beside the first linear module 61. A first linear slide seat 63 is slidably installed on the first linear guide rail 62. A second linear module 64 is installed at the drive end of the first linear module 61. One end of the second linear module 64 is connected to the first linear slide seat 63. A linear sliding seat 63 is connected, and the second linear module 64 is arranged laterally perpendicular to the first linear module 61. A longitudinal drive frame 65 is installed at the drive end of the second linear module 64, and a longitudinally arranged third linear module 66 is installed on the longitudinal drive frame 65. A lifting drive platform 67 is installed at the drive end of the third linear module 66, and an inspection fixing platform 68 is installed on the lifting drive platform 67. A drive motor is installed on the inspection fixing platform 68, and a top rotating platform 69 capable of lateral rotation is installed at the drive end of the drive motor. The inspection drive seat 60 is installed on the top rotating platform 69. In this embodiment, driven by the four-axis adjustment drive module 6 (X, Y, Z, R axis adjustment), the first inspection module 51 and the second inspection module 52 can be adapted to battery trays 4 of different sizes and shapes without replacing core components such as the inspection drive seat 60. The four-axis adjustment drive module 6 of the first inspection seat 53 and the second inspection seat 54 achieves full-dimensional precise positioning of the inspection drive seat 60, ensuring absolute alignment of the diagonal inspection optical path with the battery, thus guaranteeing inspection accuracy.

[0047] Furthermore, the first light-collecting plate 55 and the first light generator 56 of the first inspection seat 53 are respectively installed on the corresponding inspection drive seat 60; the second light-collecting plate 57 and the second light generator 58 of the second inspection seat 54 are respectively installed on the corresponding inspection drive seat 60; the first light generator 56 and the second light generator 58 are both light-emitting elements that irradiate light along the tangential direction of the battery surface, and the first light-collecting plate 55 and the second light-collecting plate 57 are photosensitive elements that collect the light after the object under test has acted upon them.

[0048] In this embodiment, after the battery tray 4 arrives at the first inspection module 51, the battery conveyor belt 33 pauses operation. At this time, the first light generator 56 of the first inspection seat 53 and the first light receiving plate 55 of the second inspection seat 54 perform visual inspection on the front right corner, and the first light generator 56 of the second inspection seat 54 and the first light generator 56 of the first inspection seat 53 perform visual inspection on the front left corner. After the inspection is completed, the tray lifting mechanism 7 operates, and the lifting platform 73 lifts the battery tray 4 from the conveyor belt. Then, the rotating platform 75 rotates 180°, and the battery tray 4 rotates 180° accordingly, so that the other two corners face the first light generator 56 and the second light generator 58 for secondary inspection. This ensures that the appearance of all four corners of the battery is inspected, and the inspection coverage is extremely wide. The fully automated operation avoids battery bumps and scratches caused by manual handling, reducing the battery scrap rate.

[0049] The pallet lifting mechanism 7 also includes a support column 71 installed at the bottom of the battery conveying rack 31. A vertical linear module 72 is arranged along the length of the support column 71. A lifting platform 73 is installed at the drive end of the vertical linear module 72. A DD motor 74 is installed on the lifting platform 73, and the drive end of the DD motor 74 is connected to the rotating platform 75. The locking structure 76 includes a pair of spaced-apart locking blocks 38. The top of each locking block 38 has a flared structure 77 for guiding and embedding the battery pallet 4. The DD motor 74 has high torque density, easily driving the combined weight of the rotating platform 75 and the battery pallet 4, with no torque fluctuation during rotation, and no impact shaking when the rotating platform 75 starts or stops. The flared structure 77 at the top of the locking block 38 provides a guide entrance for the pallet, facilitating the locking and positioning of the battery pallet 4.

[0050] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0051] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
