Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a detection device and an error correction system. Background Technology

[0002] With the widespread application of lightweight products such as new energy vehicles and battery systems, aluminum profile enclosures have become an important choice for structural components of energy storage systems and battery packs due to their advantages such as light weight, high strength, and good corrosion resistance. Aluminum profile enclosures are typically welded from aluminum profiles of various cross-sections using friction stir welding to meet the complex structural designs and the different strength, heat dissipation, and assembly requirements of various functional areas.

[0003] Reference Figure 1 Due to limitations in aluminum profile extrusion processes and the actual requirements of the box structure design, some profiles in the box are often flat profiles. Furthermore, to meet the requirements of extreme weight reduction and wall thickness in different functional areas, the flat profiles typically have a difference in wall thickness between their upper and lower surfaces. The flat profile includes a first plate and a second plate positioned opposite each other, with an opening formed between them. The first plate is thicker than the second plate. This difference in wall thickness between the first and second plates satisfies the comprehensive requirements of structural strength, thermal management, and processing technology.

[0004] However, due to the lack of obvious distinguishing features on the surface of flat profiles and the difficulty in directly identifying the difference in wall thickness between the upper and lower sections, incorrect clamping orientation is prone to occur during actual processing. If operators fail to correctly identify the clamping orientation of the flat profile, it is highly likely to lead to incorrect clamping of the machined surface, resulting in machining position deviations and scrapped parts. More seriously, if this error is not detected in time in earlier processes, it may cause defective parts to flow into subsequent welding or battery pack assembly processes, creating cascading quality risks and potentially even leading to the scrapping of the entire case or battery pack, causing significant economic losses and impacting production efficiency. Utility Model Content

[0005] One objective of this invention is to provide a detection device and an error correction system, which aims to solve the technical problem that the clamping direction of flat profiles is prone to errors during processing.

[0006] To achieve the above objectives, this utility model provides a solution: a detection device and error correction system, comprising: a support platform, a detection component, and a sensor. The support platform supports a flat profile, which includes a first plate and a second plate disposed opposite to each other, with an opening formed between them. The thickness of the first plate is greater than the thickness of the second plate. The detection component includes a first gripper and a first driving member. The output end of the first driving member is connected to the first gripper. The first driving member drives the first gripper to move towards or away from the flat profile. A first channel and a second channel are formed on the side of the first gripper away from the first driving member. The height of the first channel is greater than the height of the second channel. The first channel is used to fit the first plate, and the second channel is used to fit the second plate. The sensor detects the moving distance of the first gripper.

[0007] Optionally, the first gripper includes a base and a guide portion, the base having a groove, the guide portion being disposed in the groove, and the guide portion forming a first channel and a second channel by dividing the groove.

[0008] Optionally, the guide portion extends beyond the groove and moves away from the groove, with the thickness of the guide portion gradually decreasing as it extends beyond the groove.

[0009] Optionally, the detection device includes a clamping assembly, which includes a second gripper and a second drive member. The second gripper has a third channel. The output end of the second drive member is connected to the second gripper. The second drive member is used to drive the second gripper to move toward or away from the flat profile. The third channel is used to simultaneously accommodate the first plate and the second plate.

[0010] Optionally, the support platform is recessed along its thickness direction to form a limiting space, which is used to accommodate the flat profile, and the first gripper moves toward or away from the limiting space.

[0011] Optionally, the testing device includes a transport component, a support platform forming an installation space, the installation space and a limiting space being connected, the transport component being movably disposed in the installation space, and the transport component being used to drive the flat profile through and into the limiting space.

[0012] Optionally, the transport component includes a conveyor belt and a third drive unit, which are disposed in the installation space. The output end of the third drive unit is connected to the first conveyor belt, and the third drive unit is used to drive the conveyor belt to move out of and into the limiting space.

[0013] Secondly, an error correction system includes a flipping device and a detection device. The flipping device includes a fourth driving member and a fixing component. The fixing component is used to fix the flat profile. The output end of the fourth driving member is connected to the fixing component. The fourth driving member is used to drive the fixing component to rotate.

[0014] Optionally, the fixing component includes a first clamping member, a second clamping member, a fifth driving member, and a frame. The frame is connected to the output end of the fourth driving member. The first clamping member and the second clamping member are both disposed on the frame. The fifth driving member is connected to the frame. The output end of the fifth driving member is connected to the first clamping member. The fifth driving member is used to drive the first clamping member to move toward or away from the second clamping member.

[0015] Optionally, the error correction system includes a first transfer component disposed between the detection device and the flipping device, the first transfer component being used to transport the flat profile from the detection device to the flipping device; and / or

[0016] The error correction system includes a second transfer component, which is located on one side of the detection device and is used to transport the flat profile to the detection device.

[0017] The beneficial effects of this utility model are as follows:

[0018] The testing device includes a support platform, a testing component, and a sensor. The support platform supports the flat profile. The testing component includes a first gripper and a first drive member. The output end of the first drive member is connected to the first gripper. The first drive member drives the first gripper to move towards or away from the flat profile. A first channel and a second channel are formed on the side of the first gripper away from the first drive member. The height of the first channel is greater than the height of the second channel. The first channel is used to fit a first plate, and the second channel is used to fit a second plate. The sensor detects the moving distance of the first gripper.

[0019] In practical applications, when the first gripper moves under the drive of the first driving component, if the clamping direction of the flat profile is correct, the first plate can be smoothly inserted into the first channel, and the second plate can be smoothly inserted into the second channel. At this time, the movement of the first gripper is unimpeded. However, if the clamping direction of the flat profile is incorrect, the first plate cannot be inserted into the second channel because its thickness exceeds the height of the second channel. Physical interference will occur during the movement of the first gripper, causing its movement distance to be significantly less than the distance when the direction is correct. A sensor is used to detect the movement distance of the first gripper in real time. The sensor has a preset movement distance threshold, which is between the movement distance when the direction is correct and the movement distance when the direction is incorrect. When the sensor detects that the movement distance of the first gripper is greater than the movement distance threshold, the clamping direction of the flat profile is determined to be correct; when the detected movement distance is less than the movement distance threshold, the clamping direction of the flat profile is determined to be incorrect. This detection scheme fully utilizes the thickness difference between the first and second plates of the flat profile and makes accurate judgments based on the movement interference of the first gripper. It effectively avoids the risk of missed detections that exist in manual visual error prevention, improves detection accuracy and efficiency, and reduces the production scrap rate caused by incorrect clamping direction.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 Due to limitations in aluminum profile extrusion processes and the actual requirements of the box structure design, some profiles in the box often use flat profiles 90. Furthermore, to meet the requirements of extreme weight reduction and wall thickness in different functional areas, the flat profile 90 typically has a difference in wall thickness between its upper and lower surfaces. The flat profile 90 includes a first plate 91 and a second plate 92 arranged opposite each other, with an opening 93 formed by the gap between the first plate 91 and the second plate 92. The thickness of the first plate 91 is greater than the thickness of the second plate 92. This difference in wall thickness between the first plate 91 and the second plate 92 satisfies the comprehensive requirements of structural strength, thermal management, and processing technology.

[0033] However, since the surface of the 90-degree flat profile lacks obvious distinguishing features and the difference in wall thickness between the upper and lower sections is not easily identifiable visually, it is easy to encounter the problem of incorrect clamping direction during actual processing.

[0034] Firstly, referring to Figures 2 to 4 This utility model provides a detection device, including a support platform 20, a detection component 30, and a sensor 40. The support platform 20 supports a flat profile 90. The detection component 30 includes a first gripper 31 and a first drive member 32. The output end of the first drive member 32 is connected to the first gripper 31. The first drive member 32 drives the first gripper 31 to move towards or away from the flat profile 90. A first channel 311 and a second channel 312 are formed on the side of the first gripper 31 away from the first drive member 32. The height of the first channel 311 is greater than the height of the second channel 312. The first channel 311 is used to adapt to a first plate 91, and the second channel 312 is used to adapt to a second plate 92. The sensor 40 is used to detect the moving distance of the first gripper 31.

[0035] In practical applications, when the first gripper 31 moves under the drive of the first driving member 32, if the clamping direction of the flat profile 90 is correct, the first plate 91 can be smoothly inserted into the first channel 311, and the second plate 92 can be smoothly inserted into the second channel 312. At this time, the movement of the first gripper 31 is unimpeded. When the clamping direction of the flat profile 90 is incorrect, the first plate 91 cannot be inserted into the second channel 312 because its thickness is greater than the height of the second channel 312. The first gripper 31 will experience physical interference during movement, resulting in a movement distance that is significantly less than the movement distance when the direction is correct. The sensor 40 is used to detect the movement distance of the first gripper 31 in real time. The sensor 40 has a preset movement distance threshold, which is between the movement distance when the direction is correct and the movement distance when the direction is incorrect. When the sensor 40 detects that the movement distance of the first gripper 31 is greater than the movement distance threshold, it determines that the clamping direction of the flat profile 90 is correct; when the detected movement distance is less than the movement distance threshold, it determines that the clamping direction of the flat profile 90 is incorrect. This inspection scheme makes full use of the thickness difference between the first plate 91 and the second plate 92 of the flat profile 90, and makes accurate judgments based on the movement interference of the first gripper 31. It effectively avoids the risk of missed inspections that exist in manual visual error prevention, improves the accuracy and efficiency of inspection, and reduces the production scrap rate caused by incorrect clamping direction.

[0036] In this embodiment, the sensor 40 can be a laser displacement sensor 40 or a photoelectric encoder, etc., and the first driving component 32 can be a cylinder with a force control regulating valve, an electric cylinder with a torque sensor 40, or a hydraulic cylinder with a hydraulic proportional valve, etc. Taking a cylinder with a force control regulating valve as an example, the reason for requiring the first driving component 32 to have a force control function is explained: using low intake air pressure to provide power to the cylinder reduces the cylinder's thrust; controlling the actual working air pressure of the cylinder through the force control regulating valve, and calculating the cylinder thrust through the air pressure, controlling the thrust to be less than the critical value for damage to the flat profile 90, so that when the clamping direction of the flat profile 90 is incorrect, the pressure of the first gripper 31 on the flat profile 90 is less than the critical value for damage to the flat profile 90, thereby ensuring that even if the clamping direction of the flat profile 90 is incorrect, the first gripper 31 will not cause damage to the flat profile 90 during the detection process. The sensor 40 can be used in conjunction with the controller and the alarm to send a signal to the controller when the clamping orientation of the flat profile 90 is incorrect. The controller then controls the alarm to sound an alarm to remind the operator that the clamping orientation of the flat profile 90 is incorrect.

[0037] In one embodiment, see Figure 4 The first gripper 31 includes a base 313 and a guide portion 314. The base 313 has a groove 3131, and the guide portion 314 is disposed in the groove 3131. The guide portion 314 divides the groove 3131 to form a first channel 311 and a second channel 312.

[0038] In practical applications, the guide portion 314 serves as a partition structure within the gripper. On one hand, it clearly separates the first channel 311 and the second channel 312, ensuring that the first plate 91 and the second plate 92 can be accurately inserted into their respective channels, preventing mis-insertion or jamming during clamping. On the other hand, the flat profile 90 can move along the guide portion 314 during clamping, improving the smoothness of profile insertion and measurement and assembly efficiency.

[0039] Further, see Figure 4 The guide portion 314 extends beyond the groove 3131 and moves away from the groove 3131. The thickness of the guide portion 314 extending beyond the groove 3131 gradually decreases.

[0040] In practical applications, by designing the guide portion 314 to extend beyond the groove 3131 and in a direction away from the groove 3131, while gradually reducing the thickness of the extended portion of the guide portion 314 to form a wedge-shaped or inclined structure, the first channel 311 and the second channel 312 form an flared shape on the side near the flat profile 90, thereby facilitating the insertion of the flat profile 90 into the first channel 311 and the second channel 312 and reducing the difficulty of insertion and alignment. The first plate 91 and the second plate 92 of the flat profile 90 can be gradually inserted into the first channel 311 and the second channel 312 guided along the inclined surface of the guide portion 314, avoiding scratches or clamping failures caused by collisions, jamming, or alignment deviations.

[0041] In one embodiment, see Figure 5 and Figure 6 The detection device includes a clamping assembly 50, which includes a second gripper 51 and a second drive member 52. The second gripper 51 forms a third channel 511. The output end of the second drive member 52 is connected to the second gripper 51. The second drive member 52 is used to drive the second gripper 51 to move toward or away from the flat profile 90. The third channel 511 is used to simultaneously accommodate the first plate 91 and the second plate 92.

[0042] In practical applications, the second driving component 52 drives the second gripper 51 to move, so that the second gripper 51 moves toward the flat profile 90 and clamps the flat profile 90. The flat profile 90 is inserted into the third channel 511, ensuring that the flat profile 90 is firmly fixed during the testing process, and avoiding measurement errors or testing failures caused by vibration, loosening or displacement of the flat profile 90.

[0043] In this embodiment, the height of the third channel 511 is adapted to the thickness of the flat profile 90 in the thickness direction. When the second gripper 51 clamps the flat profile 90, the second plate 92 abuts against the support platform 20, and the first plate 91 abuts against the inner wall of the third channel 511, thereby restricting the movement of the flat profile 90 in the thickness direction.

[0044] In one embodiment, see Figure 2 and Figure 3 The support platform 20 is recessed along its thickness direction to form a limiting space 21, which is used to accommodate the flat profile 90. The first gripper 31 moves toward or away from the limiting space 21.

[0045] In practical applications, by recessing the support platform 20 along its thickness direction to form a limiting space 21, the limiting space 21 becomes a dedicated installation and positioning area for accommodating the flat profile 90. This effectively restricts the placement position and posture of the flat profile 90 on the support platform 20, ensuring that the flat profile 90 is fixed in position and has a clear clamping direction during the testing process. This helps to improve the stability of the testing process and the accuracy of the testing results.

[0046] Furthermore, referring to Figure 5 The detection device includes a transport component 60, a support platform 20 forming an installation space 22, the installation space 22 and the limiting space 21 are connected, the transport component 60 is movably disposed in the installation space 22, and the transport component 60 is used to drive the flat profile 90 to pass through and into the limiting space 21.

[0047] In practical applications, an installation space 22 is set on the support platform 20 and connected to the limiting space 21. A transport component 60 is installed within the installation space 22, allowing the transport component 60 to move within it. The transport component 60 drives the flat profile 90 to reciprocate along paths entering and exiting the limiting space 21. When the flat profile 90 needs inspection, the transport component 60 actively transports it into the limiting space 21, facilitating its entry into the clamping and inspection station for subsequent inspection by the first gripper 31. When inspection is complete or the flat profile 90 needs to be replaced, the transport component 60 can transport it out of the limiting space 21, reducing the frequency of manual handling and adjustment. Through the structural cooperation between the transport component 60, the limiting space 21, and the installation space 22, it is ensured that the profile always moves along a set path during entry and exit, preventing inspection interference or loading / unloading failures due to profile deviation or swaying.

[0048] Furthermore, referring to Figure 5 The transport component 60 includes a conveyor belt 61 and a third drive member 62, which are disposed in the installation space 22. The output end of the third drive member 62 is connected to the first conveyor belt 61. The third drive member 62 is used to drive the conveyor belt 61 to move out of and into the limiting space 21.

[0049] In practical applications, by setting a conveyor belt 61 in the transport component 60 and connecting the output end of the third drive unit 62 to the conveyor belt 61, the third drive unit 62 can drive the conveyor belt 61 to move along the installation space 22, thereby realizing the conveyor belt 61 to transport the flat profile 90. Specifically, this includes passing the flat profile 90 out of the limiting space 21 to complete the unloading operation after inspection, and passing the flat profile 90 to be inspected into the limiting space 21 to complete the loading operation.

[0050] In this embodiment, by setting a conveyor belt 61 in the transport component 60 and connecting the output end of the third drive member 62 to the conveyor belt 61, the third drive member 62 can drive the conveyor belt 61 to move along the installation space 22, thereby realizing the conveying function of the conveyor belt 61 for transporting the flat profile 90. Specifically, the third drive member 62 drives the flat profile 90 to move through the limit space 21 via the conveyor belt 61, and then the conveyor belt 61 drives the flat profile 90 to complete the unloading operation after inspection. Additionally, the third drive member 62 drives the flat profile 90 to move in the opposite direction via the conveyor belt 61 to move into the limit space 21 to complete the loading operation of transporting the flat profile 90 to be inspected to the limit space 21. The third drive member 62 can be a cylinder, servo cylinder, hydraulic cylinder, or electric slide, etc.

[0051] Secondly, referring to Figure 7 A correction system is provided, including a flipping device 70 and a detection device in the above embodiment. The flipping device 70 includes a fourth driving member 71 and a fixing component 72. The fixing component 72 is used to fix the flat profile 90. The output end of the fourth driving member 71 is connected to the fixing component 72, and the fourth driving member 71 is used to drive the fixing component 72 to rotate.

[0052] In practical applications, the fixing component 72 is used to clamp and stabilize the flat profile 90 to be tested, ensuring that the profile will not loosen or slip during the flipping process; the fourth driving component 71 drives the fixing component 72 to rotate as a whole by rotating the output end, thereby realizing the flipping of the flat profile 90.

[0053] Specifically, when the detection device determines that the flat profile 90 is clamped in the wrong direction based on the movement distance of the first gripper 31, it transports the flat profile 90 to the flipping device 70 without changing the relative positions of the first plate 91 and the second plate 92. The flat profile 90 is then fixed to the fixing assembly 72, and the fourth driving component 71 drives the fixing assembly 72 to flip the flat profile 90 to the correct direction. The flipping device 70 works in conjunction with the detection device to achieve closed-loop control of detection and error correction, preventing defective products caused by incorrect clamping direction from flowing into subsequent processes, effectively improving the first-pass yield and reducing rework and scrap costs. The fourth driving component 71 can be a servo motor or a stepper motor, or other driving devices.

[0054] Furthermore, referring to Figure 7 The fixing component 72 includes a first clamping member 721, a second clamping member 722, a fifth driving member 723, and a frame 724. The frame 724 is connected to the output end of the fourth driving member 71. The first clamping member 721 and the second clamping member 722 are both disposed on the frame 724. The fifth driving member 723 is connected to the frame 724. The output end of the fifth driving member 723 is connected to the first clamping member 721. The fifth driving member 723 is used to drive the first clamping member 721 to move toward or away from the second clamping member 722.

[0055] In practical applications, in the flipping device 70, the first clamping member 721 and the second clamping member 722 are respectively mounted on the frame 724. The frame 724 is installed through the output end of the fourth driving member 71 and rotates together with the output end of the fourth driving member 71. The output end of the fifth driving member 723 is connected to the first clamping member 721. Driven by the fifth driving member 723, the first clamping member 721 can move towards or away from the second clamping member 722. During clamping, the fifth driving member 723 drives the first clamping member 721 to move towards the second clamping member 722, clamping the flat profile 90 between the clamping members to ensure that the profile remains stable and does not slip during subsequent flipping.

[0056] After clamping is completed, the fourth drive unit 71 is activated, driving the frame 724 and the clamped flat profile 90 to rotate around the output shaft of the fourth drive unit 71, thereby achieving the overall rotation of the flat profile 90. When it is rotated to a preset angle (such as 180°), the fourth drive unit 71 stops moving, and the clamping component is released by the fifth drive unit 723, releasing the flat profile 90.

[0057] The flipped flat profile 90 is then conveyed to the inspection device for orientation re-inspection. This process ensures that flat profiles 90 with incorrect clamping orientation are flipped and corrected in a timely manner within the system, effectively preventing errors from flowing into the next process.

[0058] In this embodiment, both the first clamping member 721 and the second clamping member 722 are conveyor belts 61, enabling them to not only clamp the flat profile 90 but also transport it to the flipping device 70 or the detection device. The fifth driving member 723 can be a cylinder, servo cylinder, hydraulic cylinder, or electric slide, etc.

[0059] Furthermore, referring to Figure 7The error correction system includes a first transfer component 80, which is disposed between the detection device and the flipping device 70, and is used to transport the flat profile 90 at the detection device to the flipping device 70; and / or the error correction system includes a second transfer component 80, which is disposed on one side of the detection device, and is used to transport the flat profile 90 to the detection device.

[0060] In practical applications, the first transfer component 80 is positioned between the detection device and the flipping device 70. When the detection device identifies an incorrect clamping orientation of the flat profile 90, it receives the flat profile 90 transferred from the transport component 60 or the clamping component 50 and smoothly and accurately transfers it to the flipping device 70, facilitating subsequent clamping and flipping operations. The first transfer component 80 enables automatic docking of the flat profile 90 between devices, avoiding manual handling, improving transfer efficiency, and reducing the risk of profile collisions and scratches, thus ensuring product quality.

[0061] The second transfer unit 80 is located on one side of the testing device and is used to transport the flat profile 90 to be tested from the previous process or storage station to the testing device. The second transfer unit 80 automates the feeding process, helps to continuously supply the profile to be tested, ensures the continuous operation of the testing device, improves the overall testing efficiency, and effectively reduces human intervention, labor intensity, and operational errors.

[0062] In this embodiment, the first transfer component 80 and the second transfer component 80 are conveyor belts 61. In other embodiments of this application, the first transfer component 80 and the second transfer component 80 may also be robotic arms or other transportation devices.

[0063] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0064] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
