Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a battery management system control housing size detection device. Background Technology

[0002] During battery production, the dimensions of cylindrical battery casings need to be accurately measured. Existing equipment typically uses industrial cameras in conjunction with other components to achieve automatic detection, followed by manual or automated feeding. However, during the feeding stage, due to untimely operation or insufficient precision of the mechanism, empty workstations occasionally appear on the conveyor line. Although this situation does not affect the normal inspection process, it can disrupt the continuous operation flow or require manual intervention to replenish the casings.

[0003] Therefore, there is a need for equipment that can automatically detect empty spaces and replenish materials in a timely manner to improve the overall operating efficiency of the production line. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that are prone to empty spaces, and to propose a battery management system control housing size detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery management system control housing size detection device includes a housing and a detection component installed inside the housing;

[0007] The conveying mechanism extends into the interior of the housing and is located below the detection components;

[0008] Multiple placement components are equidistantly arranged on the surface of the conveyor belt of the conveying mechanism. Each placement component includes a placement seat, which is fixedly arranged on the surface of the conveyor belt of the conveying mechanism. The top of the placement seat has an inner cavity for embedding the battery housing.

[0009] A replenishment assembly is installed on the frame of the conveying mechanism and located above the placement component. The replenishment assembly includes a replenishment box and a fixing frame fixedly installed on both sides of its outer wall. The other end of the fixing frame is fixedly installed on the side wall of the conveying mechanism frame. The interior of the replenishment box is used to fill the outer shell of the cylindrical battery and arranged vertically in sequence.

[0010] In one possible design, the detection component includes an industrial CCD camera and a dual telecentric lens.

[0011] In one possible design, the conveying mechanism is a chain conveyor that moves intermittently according to a set rhythm, causing the placement seat carrying the battery casing to pause at the inspection station to cooperate with the inspection components to complete the dimensional analysis.

[0012] In one possible design, the replenishment assembly further includes a partition and a backing plate. The side wall of the replenishment box has a side hole. One end of the partition is laterally inserted into the interior of the replenishment box through the side hole. A side seat is fixedly provided on the side wall of the partition. A guide rod is fixedly provided on the side wall of the replenishment box. The side seat is slidably sleeved on the outer wall of the guide rod. A compression spring is sleeved on the outer wall of the guide rod, and both ends are respectively fixedly provided on the boss on the outer wall of the guide rod and the side wall of the side seat.

[0013] The compression spring provides a restoring force to the partition, allowing it to automatically reset after refilling and re-separate the outer shell inside the refill box.

[0014] In one possible design, a fixing seat is fixedly installed on the side wall of the fixing frame, a connecting shaft is rotatably installed on the top of the fixing seat, the abutment is fixedly sleeved on the outer wall of the connecting shaft, a guide ring is fixedly sleeved on the outer wall of the connecting shaft, a guide groove is opened on the outer wall of the guide ring, and the guide groove is arc-shaped and extends into the guide ring, a connecting frame is fixedly installed on both side walls of the partition, and the other end of the connecting frame cooperates with the guide groove, a limit seat is fixedly installed on the side wall of the fixing frame, and a torsion spring is installed at the rotation point of the connecting shaft;

[0015] The torsion spring keeps the plate in its initial position, the limit seat ensures the plate rotates accurately, and the rotational motion of the plate is converted into the lateral movement of the partition through the cooperation of the guide ring and the connecting frame.

[0016] In one possible design, the placement component further includes two auxiliary strips. The inner wall of the bottom of the placement base has grooves on both sides, and the placement base has movable holes on both sides, with the movable holes communicating with the grooves on the same side. The auxiliary strips are rotatably disposed inside the movable holes via a pivot, with one end engaging with the groove and the other end engaging with the abutment.

[0017] When the placement seat is empty, the auxiliary strip naturally droops due to the weight difference between its two ends; when the placement seat is equipped with a battery casing, the weight of the casing causes the inner end of the auxiliary strip to press down and the outer end to tilt up, thus avoiding contact with the backing plate.

[0018] In this application, in actual use, the cylindrical battery casing is sequentially filled into the placement seat of the placement component by a manual or automatic feeding mechanism, and then sent to the inside of the casing by a conveying mechanism. The size detection of the battery casing is achieved by the industrial CCD camera and dual telecentric lens of the detection component.

[0019] When the battery casing is installed inside the placement seat, it will press down on one end of the raised auxiliary strip, causing it to fit into the groove. The other end, located on the outside, will be raised to avoid the abutment. When there is an empty placement piece, since the outer end of the auxiliary strip is longer than the other end, it will hang down naturally. When it moves to one side of the replenishment assembly, it will abut against the abutment, thus pushing it to rotate. The abutment drives the connecting shaft to rotate, which in turn drives the guide ring to rotate. The guide groove on the outer wall of the guide ring rotates synchronously, thus pushing the end of the connecting frame to move outward. The connecting frame will then drive the partition to move laterally. During the pause in the detection, the casing inside the replenishment box will fall down into the placement seat for replenishment. After this placement piece is removed, it will continue to push the abutment to rotate a certain angle. Then, it can be reset by the torsion spring, and the partition will be reset by the compression spring, thus re-dividing the inside of the replenishment box.

[0020] Furthermore, since the top of the outer wall surface of the battery casing will be flush with the top of the casing after it is installed inside the placement seat, this prevents the casing at the bottom of the replenishment box from falling further down when the replenishment unit with the casing is removed but the separator has not yet returned to its original position, until the separator is reset and re-contacts the casing to act as a barrier.

[0021] In this utility model, the battery management system control housing size detection device, through the anti-misoperation structure, can achieve the following: when the battery housing is installed in the placement seat, the housing's own weight presses down on one end of the auxiliary strip, causing its outer raised end to automatically avoid the abutment plate, thus avoiding accidental triggering of the material replenishment action. In addition, the design that the top of the housing is flush with the top surface of the placement seat effectively prevents the housing from continuing to fall when the partition plate is not fully reset.

[0022] In this utility model, the battery management system control housing size detection device can achieve the conversion of the empty state of the placement seat through the interaction of the auxiliary strip and the backing plate, and drive the partition to control the feeding, realizing intelligent recognition without the need for additional sensors.

[0023] In this invention, during use, the device can automatically detect empty spaces and replenish materials. When the placement seat on the conveyor belt is empty, the device can promptly implement a replenishment mechanism, replenishing the housing while the detection process is underway, ensuring continuous operation of the production line.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] In one embodiment: Reference Figure 1 A shell size detection device for detecting cylindrical shells includes: a housing 1, a detection component 111, a conveying mechanism 4, a placement component 3, and a feeding component 2.

[0033] The conveying mechanism 4 is a chain conveyor that extends through the interior of the housing 1. Multiple placement pieces 3 are arranged at fixed intervals on the surface of the conveyor belt. Each placement piece 3 includes a placement seat 311, and a cylindrical inner cavity opened at the top of the seat is used to embed a cylindrical battery housing.

[0034] refer to Figure 2The detection component 111 is installed inside the top of the housing 1, including a high-resolution industrial CCD camera and a dual telecentric lens combination. Specifically, it can use the detection component in existing detection equipment such as the CC512, and is directly opposite the placement seat 311 on the conveyor mechanism 4 below. When the conveyor mechanism 4 moves intermittently according to the set rhythm, the placement seat 311 carrying the battery housing stops at the detection station. The detection component 111 collects the housing image data and transmits it to the processing system for dimensional analysis. The industrial CCD camera and the dual telecentric lens form an image acquisition system. The system extracts the edge features of the housing through a preset contour recognition algorithm, converts the pixel coordinates into actual physical dimensions, and automatically determines whether the product is qualified by comparing the actual measured value with the standard tolerance range.

[0035] refer to Figure 3 The feeding assembly 2 is located above the inlet area of ​​the conveying mechanism 4. The feeding box 211 is connected to the side wall of the conveying mechanism 4 via two side fixing frames 212. The cylindrical battery casings to be tested are vertically stacked inside the feeding box 211.

[0036] refer to Figure 4-6 A partition 214 is horizontally inserted into a side hole 217 on the side wall of the replenishment box 211. A side seat 215 is fixedly installed on the side wall of the partition 214, and the side seat 215 is slidably sleeved on the outer wall of the guide rod 216 on the side wall of the replenishment box 211. A compression spring sleeved on the outside of the guide rod 216 provides a restoring force for the partition 214. A rotatable connecting shaft 222 is installed on the side wall of the fixing frame 212 through a fixing seat 221. A backing plate 218 and a guide ring 219 are fixedly sleeved on the shaft. An arc-shaped guide groove 220 on the outer edge of the guide ring 219 cooperates with the end of the connecting frame 213 fixed on the side wall of the partition 214. A torsion spring at the rotation of the connecting shaft 222 keeps the backing plate 218 in its initial position.

[0037] The movable holes 313 on both sides of the outer wall of the placement base 311 are connected to the grooves 312 on both sides of the inner wall of its bottom. The auxiliary strip 314 is installed in the movable holes 313 through a pivot, with the end inside the placement base 311 being the short end and the end outside being the long end. When the placement base 311 is empty, the auxiliary strip 314 naturally droops due to the weight difference between the two ends; when the battery casing is installed, the weight of the casing causes the inner end of the auxiliary strip 314 to press down and the outer end to tilt upward.

[0038] Specifically, the operator or automatic feeding mechanism loads the battery casings into the placement seat 311 in sequence. The conveying mechanism 4 runs in a rhythmic manner, sending the casings into the internal inspection station of the housing 1. The inspection component 111 completes the dimensional measurement during the pause interval.

[0039] When an empty placement seat 311 passes under the replenishment assembly 2, the outer end of the drooping auxiliary bar 314 contacts the abutment plate 218, pushing it to rotate around the connecting shaft 222. The connecting shaft 222 drives the guide ring 219 to rotate, and the guide groove 220 pushes the connecting frame 213 to move outward. The connecting frame 213 drives the partition 214 to be pulled out of the replenishment box 211. At this time, the bottom battery casing falls into the empty placement seat 311 below due to loss of support. When the placement seat 311 continues to move forward, the auxiliary bar 314 disengages from the abutment plate 218, the torsion spring drives the connecting shaft 222 to reverse and reset, and the compression spring pushes the partition 214 to re-insert into the replenishment box 211, separating the upper casing, thereby achieving the effect of automatically filling empty spaces.

[0040] This application can be used in the field of battery production, or in other fields applicable to this application.

[0041] In another embodiment: Reference Figure 5 A battery management system control housing size detection device is used to detect large cylindrical lithium battery housings. It is applied to the battery production field. A corresponding limit seat 223 is fixedly installed on the side wall of the fixed frame 212 to ensure that the abutment plate 218 can ensure the accuracy of the rotation position when it is reset by the torsion spring.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the detection components and conveying mechanisms are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
