Description

Technical Field

[0001] This utility model relates to the field of power battery end plate detection technology, specifically a power battery end plate flexible positioning detection device. Background Technology

[0002] The flexible positioning and inspection device for power battery end plates is an automated production line for lithium battery modules / cells in new energy vehicles or energy storage systems. It primarily performs high-precision positioning and defect detection on battery end plates (usually made of metal) to ensure assembly accuracy and product quality stability. Existing inspection devices, such as conveyor belt online full-inspection systems, involve the end plate moving along the production line to the inspection station, triggering a photoelectric switch to start scanning. Using an industrial camera and AI image processing algorithms, it can identify micron-level scratches, indentations, missing characters, and other surface defects. Before reaching the inspection point, the end plate is moved to the center of the conveyor belt and aligned using an electric push rod and push plate, which improves inspection consistency and accuracy.

[0003] Existing testing devices require adjustment of the travel stroke of an electric actuator piston rod to adapt to battery end plates of different specifications. This results in excessively high performance requirements for the electric actuator (such as travel range and accuracy), significantly increasing production costs. Therefore, a flexible positioning testing device for power battery end plates is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible positioning and detection device for power battery end plates, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a flexible positioning and detection device for power battery end plates, comprising:

[0006] A conveyor belt vision inspection system includes a conveyor roller, a vision inspection instrument, an electric push rod, and a push plate. The vision inspection instrument is fixed on the ground, the conveyor roller passes through the vision inspection instrument, the electric push rod is fixed on both sides of the upper end of the conveyor roller, and the push plate is fixed on the movable end of the electric push rod.

[0007] The connecting assembly includes an L-shaped support plate, a movable hole, a first clamp, and a screw. The L-shaped support plate is fixed to both sides of the upper end of the conveyor roller. The movable hole is opened in the middle of one end of the L-shaped support plate. The first clamp is wrapped around the end of the electric push rod. One end of the screw is welded to one side of the first clamp, and the other end is inserted into the movable hole and tightened by a nut.

[0008] Furthermore, the connecting assembly also includes mounting holes and reinforcing plates. The mounting holes are located at the opposite end of the L-shaped support plate away from the movable hole, and the reinforcing plates are welded to both ends of the inner side of the L-shaped support plate.

[0009] Furthermore, the connecting assembly also includes a second clamp, which wraps around the end of the electric push rod near the movable end.

[0010] Furthermore, the connecting component also includes scale lines that are printed on the L-shaped support plate and located on the side of the movable hole.

[0011] Furthermore, there are two electric push rods, and they are equidistant from the side of the conveyor roller.

[0012] Furthermore, there are two push plates, which are movably connected to the upper end of the conveyor roller.

[0013] Furthermore, it also includes a moving component, which includes openings and rollers. The openings are formed on the push plate and are evenly distributed. The rollers are rotatably connected to the openings and extend outward from the openings.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through its connecting components, allows for the movement of an electric push rod when the position of the push plate needs to be adjusted according to the width of the end plate. This movement drives the first and second clamps, which in turn move the screw along the movable hole. Once the screw reaches the appropriate position, the nut on the screw is tightened. The scale lines ensure that the electric push rods on both sides are at the same distance from the side of the conveyor roller. This design, through the combination of the L-shaped support plate, the movable hole, and the screw, enables the electric push rod to move flexibly along the axial direction, allowing the push plate position to be adjusted without adjusting the electric push rod's travel parameters.

[0024] Please see Figure 1-3 As shown, this utility model is a flexible positioning and detection device for a power battery end plate, comprising:

[0025] The conveyor belt vision inspection system includes a conveyor roller 10, a vision inspection instrument 11, an electric push rod 12, and a push plate 13. The vision inspection instrument 11 is fixed on the ground, the conveyor roller 10 passes through the vision inspection instrument 11, the electric push rod 12 is fixed on both sides of the upper end of the conveyor roller 10, and the push plate 13 is fixed on the movable end of the electric push rod 12.

[0026] There are two electric push rods 12, and they are equidistant from the side of the conveyor roller 10;

[0027] There are two push plates 13, which are movably connected to the upper end of the conveyor roller 10;

[0028] The conveyor roller 10 serves as a support, conveying the power battery end plate to the vision inspection instrument 11. The vision inspection instrument 11 is used to detect surface defects of the battery end plate, using an industrial camera and AI image processing algorithm to identify defects. The industrial camera model can be Basler acA1920-150um. The electric push rod 12 can change position, and the model can be SMC CDM2 series, driving the push plate 13 to move. The two sets of electric push rods 12 and push plates 13 push the battery end plate to the middle of the conveyor roller 10. The movement of the piston rod controlled by the electric push rod 12 can be detected by the sensor when the end plate moves to the push plate 13, and the control system controls the electric push rod 12 to start.

[0029] The connecting assembly includes an L-shaped support plate 20, a movable hole 23, a first clamp 25, and a screw 27. The L-shaped support plate 20 is fixed on both sides of the upper end of the conveyor roller 10. The movable hole 23 is opened in the middle of one end of the L-shaped support plate 20. The first clamp 25 is wrapped around the end of the electric push rod 12. One end of the screw 27 is welded to one side of the first clamp 25, and the other end is inserted into the movable hole 23 and tightened by a nut.

[0030] The connecting assembly also includes a mounting hole 21 and a reinforcing plate 22. The mounting hole 21 is opened at the other end of the L-shaped support plate 20 away from the movable hole 23, and the reinforcing plate 22 is welded to both ends of the inner side of the L-shaped support plate 20.

[0031] The connecting assembly also includes a second clamp 26, which wraps around the end of the electric push rod 12 near the movable end;

[0032] The connecting component also includes a scale line 24, which is engraved on the L-shaped support plate 20 and located on the side of the movable hole 23.

[0033] The L-shaped support plate 20 provides support, the mounting hole 21 facilitates fixing the L-shaped support plate 20, the reinforcing plate 22 provides reinforcement, the movable hole 23 facilitates the movement of the electric push rod 12, the scale line 24 provides indication, the first clamp 25 provides connection, the second clamp 26 provides balance, and the screw 27 is used to fix the first clamp 25.

[0034] Working principle:

[0035] The first clamp 25 and the second clamp 26 are respectively clamped to both ends of the electric push rod 12. The L-shaped support plate 20 is fixed to both sides of the conveyor roller 10 through the mounting hole 21 and bolts. The screw 27 on the side of the first clamp 25 is inserted into the movable hole 23. When it is necessary to adjust the position of the push plate 13 after it has moved according to the width of the end plate, the electric push rod 12 can be moved to drive the first clamp 25 and the second clamp 26 to move, and then drive the screw 27 to move along the movable hole 23. When it moves to the appropriate position, the nut on the screw 27 is tightened. The scale line 24 can ensure that the electric push rod 12 on both sides is at the same position from the side of the conveyor roller 10. At the beginning, the piston rod at the movable end of the electric push rod 12 is in a fully retracted state. When the end plate moves to the push plate 13, the electric push rod 12 is activated, driving the piston rod to move the push plate 13, pushing the end plate to the middle of the conveyor roller 10 and aligning it.

[0036] This step, through the combination of L-shaped support plate 20, movable hole 23 and screw 27, enables the electric push rod 12 to move flexibly along the axial direction, and the position of push plate 13 can be adjusted without adjusting the travel parameters of electric push rod 12.

[0037] Please see Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The moving component includes an opening 30 and a roller 31. The opening 30 is formed on the push plate 13 and is evenly distributed. The roller 31 is rotatably connected in the opening 30 and extends out of the opening 30.

[0039] The opening 30 facilitates the installation of the roller 31, and the roller 31 facilitates the movement of the end plate.

[0040] Working principle:

[0041] As the pusher plate 13 pushes the end plate to the middle of the conveyor roller 10 and aligns it, the end plate is constantly in motion while being driven by the conveyor roller 10. At this time, the end plate will drive the roller 31 in the opening 30 to rotate.

[0042] This step avoids wear on the end plate by the push plate 13 during the centering and alignment process, thus improving the smoothness of the positioning process.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
