Description

Technical Field

[0001] This utility model relates to the technical field of CT inspection equipment for battery production, and in particular to a transport and rotation inspection mechanism. Background Technology

[0002] In the battery cell production process, CT (Computed Tomography) inspection is a key step in ensuring battery cell quality. To improve inspection efficiency, the industry generally adopts a solution of simultaneously scanning two battery cells at opposite angles. This requires the battery cells to be accurately transported and rotated to the CT inspection station. Currently, this process is mainly achieved by two transport methods.

[0003] The first method involves adding a robotic arm to the front of the CT equipment. The robotic arm rotates the battery cells to the target angle and places them diagonally side by side on the conveyor belt. The conveyor belt then transports the battery cells to the CT testing station. The second method involves using a robotic arm to grab the battery cells and place them on a feeding platform. The rotating motion of the feeding platform then transports the battery cells to the testing station.

On the one hand, the overall cost of the mechanism is high, the control logic is complex, and the conveying accuracy is difficult to meet the requirements of high-precision testing, resulting in low testing efficiency. On the other hand, both methods involve secondary handling operations, which can easily cause bumps and squeezing to the battery cells during the handling process, posing safety hazards to the battery cells and failing to meet the high-efficiency and safe testing requirements of battery cell production.

[0025] Reference Figure 1 This embodiment provides a conveying and rotating detection mechanism, including a conveying device 1, a lifting and rotating device 2, and a detection device 3; The detection device 3 is arranged opposite to the conveying device 1, and the detection device 3 is used to detect the battery cell 4; The lifting and rotating device 2 is located at one end of the conveying device 1 near the detection device 3. The lifting and rotating device 2 is used to transfer and adjust the detection angle of the battery cell 4.

[0026] In the above embodiments, the handling and rotating inspection mechanism mainly consists of three core components: a conveying device 1, a lifting and rotating device 2, and an inspection device 3. The conveying device 1 is a linear conveying system used to carry and transport the battery cells 4. Its operating direction is linear translation, used to stably transport the battery cells 4 to be inspected from the loading position to the inspection preparation station. The lifting and rotating device 2 is located at the end of the conveying device 1 near the inspection device 3, i.e., at the end of the conveying path. Its function is to receive the delivered battery cells 4, vertically lift and lower them, and adjust their angle to achieve precise positioning of the battery cell 4's posture. The inspection device 3 is arranged opposite to the conveying device 1, independently positioned in front of the conveying path, forming an inspection channel for performing CT scan inspection on the battery cells 4 entering it. After the conveying device 1 completes the initial positioning of the battery cells 4, the lifting and rotating device 2 starts, lifting and transferring the battery cells 4 from the conveying device 1, then adjusting the rotation angle, and finally horizontally moving the battery cells 4 into the inspection area of ​​the inspection device 3. The detection device 3 and the conveying device 1 maintain a certain distance and do not directly contact each other. The transition of the battery cell 4 is entirely completed by the lifting and rotating device 2. This application directly connects the conveying and detection links through the lifting and rotating device 2 to complete the transfer and angle adjustment of the battery cell 4, eliminating the need for a traditional robotic arm, which significantly reduces equipment costs and control complexity. The lifting and rotating device 2 improves the conveying accuracy through precise positioning and drive, and eliminates the secondary handling steps, avoiding the safety hazards of the battery cell 4 being bumped. At the same time, it supports the simultaneous detection of two battery cells 4, effectively improving the detection efficiency, and ultimately achieving high-efficiency detection with low cost, high precision, and high safety, which meets the requirements for high-efficiency and safe detection of battery cells 4.

[0027] Reference Figures 1-2 In one embodiment, the conveying device 1 includes a first conveying component 10 and a second conveying component 11, the first conveying component 10 and the second conveying component 11 are arranged at a distance from each other, and the detection device 3 is disposed between the first conveying component 10 and the second conveying component 11.

[0028] In the above embodiment, the conveying device 1 consists of a first conveying component 10 and a second conveying component 11, which are arranged opposite to each other in space and at intervals to form a symmetrical conveying layout. The first conveying component 10 serves as the feeding end of the entire testing process, responsible for receiving the battery cell 4 to be tested from the external feeding system and conveying it to the front end of the testing area; the second conveying component 11 serves as the unloading end, used to receive the battery cell 4 that has completed testing and convey it to the subsequent unloading or sorting station. The testing device 3 is located between the first conveying component 10 and the second conveying component 11. The three are arranged sequentially along a straight line, but maintain a certain distance from each other and are not directly connected or in contact. The input side of the detection device 3 faces the output end of the first conveying component 10, while its output side faces the input end of the second conveying component 11, forming a detection channel with an empty space in the middle. This allows the battery cell 4 to be initially positioned by the first conveying component 10 before entering the detection stage. Then, it is transferred from the first conveying component 10 to the detection device 3 for scanning via the lifting and rotating device 2. After the detection is completed, the lifting and rotating device 2 moves the battery cell 4 out of the detection device 3 and sends it to the second conveying component 11 for unloading and conveying. This avoids the cycle delay caused by single-line back-and-forth movement and provides sufficient operating space for the detection device 3, ensuring that the detection process is not interfered with by the conveying action.

[0029] Reference Figures 1-2 In one embodiment, the first conveying assembly 10 and the second conveying assembly 11 have the same structure. The second conveying assembly 11 includes a line support 110, a drive motor 111, a conveyor belt 112, and a tray 113. The conveyor belt 112 and the drive motor 111 are respectively mounted on the line support 110, and the conveyor belt 112 is connected to the drive motor 111. The tray 113 is placed on the conveyor belt 112, and the battery cell 4 is placed in the tray 113.

[0030] In the above embodiments, the first conveying assembly 10 and the second conveying assembly 11 adopt the same structural design. Each conveying assembly mainly consists of a line support 110, a drive motor 111, a conveyor belt 112, and a tray 113. The line support 110 serves to fix and support other components. The drive motor 111 is mounted on the line support 110 and is a servo motor. Its output shaft is connected to the conveyor belt 112, driving the conveyor belt 112 to circulate through power transmission. The conveyor belt 112 is horizontally arranged above the line support 110, serving as a moving component that supports and transports the tray 113. Its surface contacts the bottom of the tray 113, and the tray 113 moves along a predetermined path by friction. The tray 113 is not fixedly placed on the conveyor belt 112 and can move synchronously with the movement of the conveyor belt 112. It has a space inside for accommodating the battery cell 4, which is stably placed inside the tray 113 and transported together with the tray 113. Since the first conveying component 10 and the second conveying component 11 have the same structure, they can be used interchangeably when they are used as the loading end and unloading end in the system, respectively, which reduces the types of spare parts and maintenance costs.

[0031] Reference Figures 1-2 In one embodiment, the line support 110 includes a first support 1101 and a second support 1102. The second support 1102 is disposed on the first support 1101. The conveyor belt 112 and the drive motor 111 are respectively disposed on the second support 1102. The lifting and rotating device 2 is disposed on the first support 1101 and is arranged correspondingly to the tray 113.

[0032] In the above embodiment, the line support 110 consists of a first support 1101 and a second support 1102. Multiple first supports 1101 are used, each with a U-shaped cross-section. Two second supports 1102 are mounted on top of the first supports 1101, spaced apart at the top of each first support 1101, forming a parallel layout. Conveyor belts 112 and drive motors 111 are both mounted on the second supports 1102. Each second support 1102 corresponds to one conveyor belt 112, and the two conveyor belts 112 operate synchronously, jointly supporting the pallet 113. The drive motor 111 is a single servo motor, mounted on the second support 1102, and simultaneously drives the two conveyor belts 112 through a synchronous transmission mechanism (such as a synchronous belt or shaft drive). The pallet 113 spans the two conveyor belts 112, with its bottom in contact with the belt surface, moving with the belts. The lifting and rotating device 2 is located in the middle of the first support 1101, in the gap between the two second supports 1102, directly opposite the running path of the pallet 113. When the tray 113 carrying the battery cell 4 moves to the designated position, it is directly opposite the lifting and rotating device 2, forming an upper and lower corresponding relationship. This position is detected and triggered by a photoelectric sensor or a mechanical limit mechanism to ensure that the tray 113 can accurately stop directly above the lifting and rotating device 2. This provides an accurate position reference for subsequent receiving and transfer, significantly improving the stability and repeatability of the transfer of the battery cell 4 and reducing the risk of detection failure due to position deviation.

[0033] Reference Figures 1-3 In one embodiment, the lifting and rotating device 2 includes a first lifting and rotating component 20 disposed on the first conveying component 10. The first lifting and rotating component 20 includes a first transplanting module 201, a first lifting component 202 and a first rotating component 203. The first transplanting module 201 is disposed on the first conveying component 10, the first lifting component 202 is movably connected to the first transplanting module 201, and the first rotating component 203 is disposed at one end of the first lifting component 202 near the detection device 3.

[0034] In the above embodiment, the lifting and rotating device 2 includes a first lifting and rotating assembly 20 disposed on the first conveying assembly 10. This assembly consists of a first transplanting module 201, a first lifting component 202, and a first rotating component 203. The first transplanting module 201 serves as the basic motion unit and is fixedly installed on the support structure of the first conveying assembly 10. Its extension direction is parallel to the conveying path of the tray 113, enabling linear movement in the horizontal direction. The first lifting component 202 is movably connected to the first transplanting module 201 and can move horizontally along the guide rail or slider of the first transplanting module 201. It also has vertical lifting capability and can reciprocate in the vertical direction. The first rotating component 203 is disposed at the end of the first lifting component 202 near the detection device 3, i.e., the side facing the detection area. As the foremost execution unit, it is responsible for adjusting the angle of the battery cell 4. The first transfer module 201 provides horizontal translational freedom, the first lifting component 202 provides vertical lifting freedom, and the first rotating component 203 provides rotational angular freedom around an axis, enabling precise transfer and attitude change of the battery cell 4 from the conveying position to the detection position. After the tray 113 carrying the battery cell 4 is positioned on the first conveying assembly 10, the first lifting component 202 moves under the drive of the first transfer module 201 to directly below the tray 113, and then moves upward to receive the tray 113; after receiving, the first rotating component 203 starts, driving the tray 113 and the battery cell 4 to rotate to the preset detection angle; finally, the first transfer module 201 pushes the entire device along with the battery cell 4 horizontally to the entrance area of ​​the detection device 3, completing the loading preparation action. This achieves the integration of lifting, rotation, and translation of the battery cell 4, enabling complex attitude adjustments without relying on an external robotic arm.

[0035] Reference Figures 1-3 In one embodiment, the first rotating component 203 includes a first rotating motor 2030 and a rotating positioning plate 2031. The first rotating motor 2030 is disposed on the first lifting component 202, and the rotating positioning plate 2031 is rotatably connected to the first rotating motor 2030. The rotating positioning plate 2031 is used to transfer and adjust the detection angle of the battery cell 4 through the tray 113.

[0036] In the above embodiment, the first rotating component 203 consists of a first rotating motor 2030 and a rotating positioning plate 2031. The first rotating motor 2030 is installed at the end of the first lifting component 202 as a power source. Its output shaft is connected to the rotating positioning plate 2031 through a coupling or reducer, enabling precise control of the rotation angle and speed. The rotating positioning plate 2031 is rotatably connected to the first rotating motor 2030 through a bearing or shaft structure, and can rotate synchronously with the motor output shaft. Its surface is provided with a positioning pin for mechanical engagement with the positioning hole 1132 at the bottom of the tray 113. When the first lifting component 202 rises to the designated position, the positioning pin on the rotating positioning plate 2031 is precisely inserted into the positioning hole 1132 of the tray 113, forming a rigid connection to ensure that the tray 113 will not slide or shift relative to each other during rotation. This allows the rotating positioning plate 2031 to directly drive the tray 113 and its internal battery cell 4 to rotate synchronously, achieving precise adjustment of the detection angle. The first rotary motor 2030 is preferably a servo motor, which, in conjunction with an encoder, provides real-time feedback on the rotation angle. After the rotation positioning plate 2031 completes the angle adjustment, it moves horizontally as a whole with the first lifting component 202 and the first transfer module 201, sending the battery cell 4 into the detection area. This achieves high-precision, programmable adjustment of the detection angle of the battery cell 4, improving detection repeatability and stability.

[0037] Reference Figures 1-3 In one embodiment, the first lifting component 202 includes a first support slide plate 2020, a first lifting motion component 2021, and a first connecting plate 2022; The first support slide plate 2020 is movably connected to the first transplanting module 201. The first support slide plate 2020 and the first connecting plate 2022 are arranged opposite to each other. The first lifting motion component 2021 is arranged between the first support slide plate 2020 and the first connecting plate 2022. The first rotating component 203 is arranged at one end of the first connecting plate 2022 near the detection device 3.

[0038] In the above embodiment, the first lifting component 202 is composed of a first supporting slide plate 2020, a first lifting motion component 2021, and a first connecting plate 2022. The first supporting slide plate 2020 serves as the mounting base for the lifting component and is movably connected to the first transplanting module 201. It can slide horizontally along the guide rail or slider of the first transplanting module 201. The first connecting plate 2022 is disposed above the first supporting slide plate 2020 and is arranged opposite to it. The two are connected by the first lifting motion component 2021 to form an upper and lower stacked structure. The first lifting motion component 2021 consists of a first lifting cylinder and two first linear bearings. All three are fixed to the top of the first supporting slide plate 2020, and the first lifting cylinder is located between the two first linear bearings in a symmetrical distribution. The first lifting motion component 2021 and the first connecting plate 2022 are arranged perpendicular to each other. The piston rod of the first lifting cylinder is connected to the first connecting plate 2022. At the same time, the two first linear bearings are connected to the first connecting plate 2022 through a linear guide shaft, forming a guide and drive composite structure. When the first lifting cylinder is activated, it pushes the first connecting plate 2022 to perform vertical reciprocating motion along the linear guide shaft. The first connecting plate 2022 is located at the top, and the first rotating component 203 is installed at the end near the detection device to support the pallet and adjust the angle, thus achieving high stability and high precision in the lifting action.

[0039] Reference Figure 1 , Figure 4 In one embodiment, the lifting and rotating device 2 includes a second lifting and rotating component 21 disposed on the second conveying component 11. The second lifting and rotating component 21 includes a second transplanting module 210, a second lifting component 211, and a second rotating component 212. The second transplanting module 210 is disposed on the second conveying assembly 11, the second lifting component 211 is movably connected to the second transplanting module 210, and the second rotating component 212 is disposed at one end of the second lifting component 211 near the detection device 3.

[0040] In the above embodiment, the lifting and rotating device 2 includes a second lifting and rotating component 21 disposed on the second conveying component 11. This component consists of a second transplanting module 210, a second lifting component 211, and a second rotating component 212, and is used to complete the receiving, posture adjustment, and unloading transfer of the battery cell 4 after detection. The second transplanting module 210 serves as a basic support and horizontal drive unit, and is fixedly installed on the structure of the second conveying component 11. Its extension direction is aligned with the conveying path of the second conveying component 11, and it is used to realize translational movement in a straight line. The second lifting component 211 is movably connected to the second transplanting module 210 and can move horizontally with it. It also has an independent vertical lifting function, and can perform upward or downward movements in the vertical direction. The second rotating component 212 is disposed at the end of the second lifting component 211 near the detection device 3, that is, the side facing the detection area, and serves as the end module for directly performing angle adjustment. When the tested battery cell 4 is transferred from the testing device 3 to the unloading handover position, the second lifting component 211, guided by the second transfer module 210, moves to below the handover point and then moves upward, where the second rotating component 212 receives the tray 113. After receiving, the second rotating component 212 can drive the tray 113 to rotate to a specified angle (e.g., 180°) to prepare for the "corner-to-corner" synchronous scanning of the next testing cycle. Then, the second transfer module 210 drives the entire device, along with the tray 113, to move horizontally back above the second conveying assembly 11. The second lifting component 211 descends, placing the tray 113 back onto the conveyor belt 112, completing the unloading. This achieves automatic receiving and angle pre-adjustment functions at the unloading end, forming a symmetrical layout with the loading end, ensuring a continuous and efficient testing process.

[0041] Reference Figure 1 , Figure 4 In one embodiment, the second rotating component 212 includes a second rotating motor 2120 and a rotating support plate 2121. The second rotating motor 2120 is disposed on the second lifting component 211, and the rotating support plate 2121 is rotatably connected to the second rotating motor 2120. The rotating support plate 2121 is used to transfer and adjust the detection angle of the battery cell 4 through the tray 113.

[0042] In the above embodiment, the second rotating component 212 consists of a second rotating motor 2120 and a rotating support plate 2121, serving as the core execution unit for adjusting the angle of the unloading end and transferring the battery cell 4. The second rotating motor 2120 is installed at the end of the second lifting component 211 and serves as a drive source. Its output shaft is connected to the rotating support plate 2121 through a reducer, enabling precise control of the rotation angle and speed to achieve accurate changes in the detection posture of the battery cell 4. The rotating support plate 2121 has a U-shaped structure and is rotatably connected to the second rotating motor 2120 via a rotating shaft or bearing, allowing it to rotate synchronously with the motor's output shaft. The U-shaped design provides it with support arms on both sides and an open area in the middle. When the tray 113 is transferred above the rotating support plate 2121, the positioning hole 1132 at the bottom of the tray 113 is located precisely in the middle of the U-shaped opening, facilitating docking with the rotating positioning plate 2031 at the loading end. This is suitable for the smooth transfer of the battery cell 4 from the detection area to the second conveying component 11.

[0043] After the current angle detection is completed, the first transfer module 201 transfers the tray 113 to the input end of the second conveying component 11 for connecting and unloading (consistent with the lifting and rotating transfer structure of the loading end). The lifting cylinder of the second lifting and rotating component 21 on the second conveying component 11 lifts up to receive the tray 113, and simultaneously releases the positioning pin of the rotating positioning plate 2031 of the first lifting and rotating component 20 at the loading end, completing the handover of the battery cell 4. The second rotating motor 2120 at the unloading end drives the tray 113 to rotate to a diagonal position (e.g., from 0° to 180°), so that the undetected angle of the detected battery cell 4 is aligned with the corresponding angle of the next battery cell 4 to be detected. At this time, the loading end has completed the rotational positioning of the new battery cell 4, and the two battery cells 4 are simultaneously transferred to the detection ring of the detection device 3 through the two transfer modules, realizing the simultaneous scanning of "the diagonal angle of the previous battery cell 4 + the initial angle of the next battery cell 4". It achieves stable reception and diagonal rotation of battery cell 4 at the unloading end, and eliminates the need for secondary handling steps, avoiding the safety hazards of battery cell 4 being bumped; at the same time, it supports simultaneous detection of dual battery cells 4, effectively improving detection efficiency.

[0044] Reference Figure 1 , Figure 4 In one embodiment, the second lifting component 211 includes a second support slide plate 2110, a second lifting motion component 2111, and a second connecting plate 2112; The second support slide plate 2111 is movably connected to the second transplanting module 210. The second support slide plate 2110 and the second connecting plate 2112 are arranged opposite to each other. The second lifting motion component 2111 is arranged between the second support slide plate 2110 and the second connecting plate 2112. The second rotating component 212 is arranged at one end of the second connecting plate 2112 near the detection device 3.

[0045] In the above embodiment, the second lifting component 211 is composed of a second support slide plate 2110, a second lifting motion component 2111, and a second connecting plate 2112. The second support slide plate 2110 serves as the mounting base of the second lifting component 211 and is movably connected to the second transplanting module 210. It can slide horizontally along the guide rail of the second transplanting module 210. The second connecting plate 2112 is disposed above the second support slide plate 2110 and is arranged vertically opposite to it. The two are connected by the second lifting motion component 2111 to form a stable hierarchical structure. The second lifting motion component 2111 consists of a second lifting cylinder and two second linear bearings, all three fixed to the top of the second support slide plate 2110. The second lifting cylinder is located between the two second linear bearings, symmetrically distributed. The second lifting motion component 2111 and the second connecting plate 2112 are arranged perpendicularly to each other. The piston rod of the second lifting cylinder is connected to the second connecting plate 2112. Simultaneously, the two second linear bearings are connected to the second connecting plate 2112 via a linear guide shaft. When the second lifting cylinder actuates, it pushes the second connecting plate 2112 to perform vertical reciprocating motion along the linear guide shaft. The second connecting plate 2112 is located at the top, and a second rotating component 212 is installed at its end near the detection device 3 for receiving and rotating the pallet. This achieves high stability and high repeatability of the lifting motion at the loading and unloading ends.

[0046] Reference Figure 1 , Figure 5 In one embodiment, the detection device 3 includes a detection bracket 30, a detection slip ring 31, a detector 32, and an X-ray tube 33. The detection slip ring 31 is movably connected to the detection bracket 30. The detector 32 and the X-ray tube 33 are respectively disposed on the detection slip ring 31, and the detector 32 and the X-ray tube 33 are arranged opposite to each other.

[0047] In the above embodiment, the detection device 3 consists of a detection bracket 30, a detection slip ring 31, a detector 32, and an X-ray tube 33. The detection bracket 30 is used to support and position other components. The detection slip ring 31 is movably connected to the detection bracket 30 and can be finely adjusted along the bracket or maintain a fixed posture. It has a ring structure and forms the main body of the detection channel, through which the battery cell 4 can pass or remain for scanning. The detector 32 and the X-ray tube 33 are respectively set on the detection slip ring 31 and are arranged opposite each other in space, that is, located on the opposite side of the detection slip ring 31, forming a X-ray path that runs through the detection area. When the X-ray tube 33 emits X-rays, the rays penetrate the battery cell 4 located in the detection area, and the attenuated signal is received by the detector 32 on the opposite side. Through data processing, a two-dimensional or three-dimensional image of the inside of the battery cell 4 is generated. The detector 32 is a CT flat panel detector, and the X-ray tube 33 is an X-ray tube. The entire testing device 3 is independently positioned within the transport path. The space between the detector 32 and the X-ray tube 33 forms the testing channel. The battery cell 4 enters this area under the transport of the lifting and rotating device 2 and remains stationary, completing multi-angle scanning. This compact structure is suitable for the high-precision requirements of online lithium battery testing, effectively improving product quality control capabilities.

[0048] Reference Figures 1-4 In one embodiment, the tray 113 includes a tray body 1130 and a plurality of support ears 1131. The support ears 1131 are disposed on the tray body 1130 and contact the conveyor belt 112. The tray body 1130 is provided with positioning holes 1132 for the first rotating component 203 to be positioned and inserted.

[0049] In the above embodiment, the tray 113 consists of a tray body 1130 and multiple support ears 1131. The tray body 1130 has an internal cavity adapted to the shape of the battery cell 4 for stably placing the battery cell 4 to be tested. The support ears 1131 are arranged on the tray body 1130, specifically two, positioned opposite each other at the middle position on both sides of the tray body 1130, with their bottom surfaces in direct contact with the surface of the conveyor belt 112. When the conveyor belt 112 is running, the friction between it and the support ears 1131 drives the entire tray 113 to move along the conveying path. A positioning hole 1132 is provided in the middle position of the tray body 1130. This hole is a through hole structure, vertically penetrating the tray body 1130, and is used to cooperate with the positioning pin on the rotating positioning plate 2031 of the first rotating component 203. When pallet 113 is moved above the lifting and rotating device 2 and requires angle adjustment, the rotating positioning plate 2031 rises, and its positioning pins are precisely inserted into the positioning holes 1132, forming a rigid connection. This ensures that pallet 113 and the rotating positioning plate 2031 rotate synchronously without relative slippage during rotation. During handover or unloading, when pallet 113 is received by the rotating support plate 2121, the U-shaped structure of the rotating support plate 2121 supports the pallet body 1130 from both sides. The positioning holes 1132 are located directly above the U-shaped opening, without affecting the receiving action. This allows pallet 113 to effectively cooperate with the conveyor belt 112 for automatic conveying, and to precisely dock with the rotating positioning plate 2031 for posture adjustment. Simultaneously, it provides stable support from the rotating support plate 2121, effectively improving the stability and detection accuracy of the battery cell 4 handling.
