[0002] The battery casing of a new energy vehicle is a core protective component of the power battery system. The battery casing is manufactured through processes such as stretching, stamping, and die casting.

[0003] During the battery casing manufacturing process, the position of the battery casing machining holes is detected to ensure the connection stability and sealing when the battery casing is assembled with the battery module. Existing detection methods use high-pixel cameras and image processing algorithms to perform non-contact detection of the battery casing mounting hole positions.

When the camera vibrates or dust adheres, it can easily cause inspection errors, resulting in defective products that need to be reworked during subsequent installation, thus reducing production efficiency.

[0005] Therefore, this utility model provides a device for detecting the position of mounting holes in the battery casing of new energy vehicles. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a device for detecting the mounting hole position of a new energy vehicle battery case, comprising a detection platform 1; a conveyor belt 10 installed in the middle of the detection platform 1; a fixed frame 11 fixedly connected to the middle of the detection platform 1; a hydraulic cylinder 12 installed in the middle of the fixed frame 11; a support plate 13 fixedly connected to the output end of the hydraulic cylinder 12; several insertion rods 14 fixedly connected to the bottom of the support plate 13; two positioning plates 15 fixedly connected to the side wall of the support plate 13; an inclined surface 16 opened on one side of the bottom of the positioning plate 15; a collection platform 17 provided at one end of the side wall of the detection platform 1; two baffles 18 fixedly connected to the top of the collection platform 17; a positioning component 2 and a pushing component 3 installed in the middle of the detection platform 1; during operation, the battery case to be monitored is placed on the conveyor belt 10, and the battery case is transported by the conveyor belt 10. The positioning component 2 positions the battery case during transport, keeping it in a designated position. When the battery case is transported to the bottom of the support plate 13, the hydraulic cylinder 12 is controlled to move it to the bottom. The output end drives the support plate 13 to move downwards. Two positioning plates 15 correspond to the two sides of the battery case. The inclined surface 16 guides the battery case between the two positioning plates 15. The battery case mounting holes correspond to several insertion rods 14. At this time, the positions of the insertion rods 14 correspond to the positions of the battery case mounting holes. When the insertion rod 14 enters the corresponding battery case mounting hole, the position is accurate. When the insertion rod 14 fails to enter the corresponding mounting hole, the position is inaccurate. When the position is inaccurate, the battery case is pushed into the collection platform 17 by the pushing component 3. The battery case in the middle of the collection platform 17 is protected by two baffles 18. The above structure can quickly detect defects in the position of the battery case mounting holes, reduce the problem of hole mismatch in the subsequent assembly process of the battery case. The insertion rods 14 can quickly complete the hole position detection, reduce complex measurement steps or data processing, effectively shorten the detection time, reduce the visual or measurement errors generated by traditional detection, and improve the efficiency of the detection work.

[0025] like Figure 1 and Figure 3As shown, the positioning component 2 includes two sets of actuators 21; the two actuators 21 form a set; the actuators 21 are mounted on the side wall of the testing table 1; the two sets of actuators 21 are arranged opposite each other; a lead screw 22 is fixedly connected to the output end of the actuator 21; a threaded cylinder 23 is installed in the middle of the lead screw 22; the threaded cylinder 23 is slidably connected to the side wall of the testing table 1; multiple support rods 24 are slidably connected to the side wall of the testing table 1; a first fixing plate 25 is fixedly connected to the end of the threaded cylinder 23 and the support rod 24; multiple rollers 26 are rotatably connected in the middle of the first fixing plate 25; a rotating belt 27 is provided in the middle of the two sets of rollers 26; during operation, during the battery case testing process, the actuators 21 are controlled by the control system to open. When the drive 21 is activated, the output end of the drive 21 drives the lead screw 22 to rotate. At this time, the first fixed plate 25 moves towards the battery housing position along with the threaded cylinder 23. The support rod 24 slides simultaneously to provide additional support for the first fixed plate 25. The rotating belts 27 on both sides are in contact with the sides of the battery housing. When the battery housing is being transported, the rotating belts 27 move accordingly. The battery housing is positioned by the two rotating belts 27. Through the above structure, the distance between the two rotating belts 27 can be quickly adjusted according to the size of the battery housing, so that the battery housing is always in the center position of the middle of the conveyor belt 10 during the transport process, reducing the battery housing from shifting during the transport process and reducing detection errors caused by the battery housing shifting or shaking.

[0026] like Figure 1 and Figure 4 As shown, the pushing component 3 includes an electric track 31; the electric track 31 is installed on the side wall of the hydraulic cylinder 12; a slider 32 is slidably connected to the middle of the electric track 31; a connecting rod 33 is fixedly connected to the end of the slider 32; a push plate 34 is fixedly connected to the end of the connecting rod 33; multiple universal balls 35 are installed at the bottom of the push plate 34; the multiple universal balls 35 are evenly distributed; during operation, when the battery case mounting hole position is unqualified, the fixing frame 11 stops, and the control system controls the electric track 31 to make the slider 32 slide in the middle. At this time, the connecting rod 33 drives the push plate 34 to push the battery case to move towards the middle of the collection platform 17. When the push plate 34 moves, the multiple universal balls 35 contact the surface of the fixing frame 11 and rotate with the movement of the push plate 34 to support the push plate 34. Through the above structure, the push plate 34 can push the unqualified battery case into the designated area, reduce equipment downtime for sorting, and enable the production line to continue operating. It can effectively reduce the mixing of unqualified battery cases with qualified battery cases and reduce secondary rework in subsequent assembly or packaging stages.

[0027] like Figure 2As shown, a plurality of second fixing rods 4 and springs 41 are fixedly connected to the middle of the support plate 13; the springs 41 are disposed outside the corresponding second fixing rods 4; a slide cylinder 42 is fixedly connected to the end of the spring 41; the slide cylinder 42 is slidably connected to the middle of the second fixing rods 4; a buffer pad 43 is fixedly connected to the end of the slide cylinder 42; during operation, when the support plate 13 moves downward, the plurality of buffer pads 43 first make flexible contact with the battery case. As the support plate 13 continues to apply pressure, the insertion rod 14 enters the corresponding mounting hole, the slide cylinder 42 slides in the middle of the second fixing rods 4, and at the same time the springs 41 generate elastic contraction. Through the above structure, the buffer pads 43 can effectively absorb the pressure generated when the support plate 13 contacts the battery case, effectively reducing the deformation or breakage caused by hard impact on the battery case.

[0028] like Figure 1 and Figure 5 As shown, a dust collection box 5 is installed on the side wall of the testing platform 1; a dust collection pipe 51 is fixedly connected to the middle of the dust collection box 5; the dust collection pipe 51 is fixedly connected to one side of the hydraulic cylinder 12; several dust collection holes 52 are opened in the middle of the dust collection pipe 51; when working, the dust collection box 5 is opened, and a negative pressure airflow is generated inside the dust collection box 5. When the battery case passes through the dust collection pipe 51, the impurities remaining on the surface of the battery case or inside the mounting hole are sucked into the dust collection pipe 51 by the negative pressure airflow. The dust collection box 5 collects particulate impurities. The above structure effectively reduces the metal chips and plastic dust remaining in the battery case during the processing, removes particulate matter in or near the holes of the battery case in real time, reduces misjudgment caused by foreign objects getting stuck when the insertion rod 14 is detected, and can reduce scratches on the surface of the battery case by impurities and debris.

[0029] like Figure 4 As shown, an elastic pad 6 is fixedly connected to the middle of the push plate 34; the elastic pad 6 is fixedly connected to one side of the corresponding collection platform 17; during operation, when the push plate 34 pushes the unqualified battery case, the elastic pad 6 makes the push plate 34 flexibly contact the battery case. The above structure can effectively reduce the hard contact between the push plate 34 and the battery case, reduce the scratches and wear on the surface of the battery case caused by the push plate 34, and maintain the integrity of the surface of the battery case.

[0030] like Figure 1 and Figure 5 As shown, two guide plates 7 are fixedly connected to the middle of the suction pipe 51; the two guide plates 7 are arranged opposite each other; the guide plates 7 are arc-shaped; when working, when the negative pressure airflow draws dust particles into the suction pipe 51, the dust and impurities are guided by the guide plates 7. Through the above structure, the guide plates 7 can restrict the airflow escape on both sides of the suction hole 52, so that the negative pressure is concentrated in the area around the suction hole 52, thereby improving the suction effect.

[0031] During operation, the battery casing to be monitored is placed on the conveyor belt 10, which transports the battery casing. The positioning component 2 positions the battery casing during transport, keeping it in a designated position. Once the battery casing reaches the bottom of the support plate 13, the transport stops. The hydraulic cylinder 12 is then controlled to move the support plate 13 downwards. Two positioning plates 15 correspond to the two sides of the battery casing, and the inclined surface 16 guides the battery casing between the two positioning plates 15. The battery casing mounting holes correspond to several insertion rods 14, which are positioned at the corresponding battery casing mounting holes. When an insertion rod 14 enters the corresponding battery casing... If the mounting hole is correctly positioned, the position is inaccurate. If the insertion rod 14 fails to enter the corresponding mounting hole, the position is inaccurate. When the position is inaccurate, the battery case is pushed into the collection platform 17 by the pushing component 3. The battery case in the middle of the collection platform 17 is protected by two baffles 18. During the battery case detection process, the control system controls the driver 21 to open. The output end of the driver 21 drives the lead screw 22 to rotate. At this time, the first fixing plate 25 moves towards the battery case position along with the threaded cylinder 23. The support rod 24 slides at the same time to provide additional support for the first fixing plate 25. The rotating belts 27 on both sides are in contact with the sides of the battery case. When the battery case is conveyed through... During the process, the rotating belt 27 moves accordingly, positioning the battery casing through the two rotating belts 27. When the battery casing mounting hole position is not up to standard, the fixing frame 11 stops, and the control system controls the electric track 31 to make the slider 32 slide in the middle. At this time, the connecting rod 33 drives the push plate 34 to push the battery casing towards the middle of the collection platform 17. During the movement of the push plate 34, multiple universal balls 35 contact the surface of the fixing frame 11 and rotate with the movement of the push plate 34, supporting the push plate 34. When the support plate 13 moves downward, multiple buffer pads 43 first make flexible contact with the battery casing, and as the support plate 13 continues to apply pressure, The insertion rod 14 enters the corresponding mounting hole, the slide cylinder 42 slides in the middle of the second fixed rod 4, and at the same time the spring 41 elastically contracts, opening the dust collection box 5. Negative pressure airflow is generated inside the dust collection box 5. When the battery case passes through the dust collection pipe 51, the negative pressure airflow sucks the impurities remaining on the surface of the battery case or inside the mounting hole into the dust collection pipe 51. The dust collection box 5 collects particulate impurities. When the push plate 34 pushes the unqualified battery case, the elastic pad 6 makes the push plate 34 flexibly contact the battery case. When the negative pressure airflow sucks the dust particles into the dust collection pipe 51, the guide plate 7 guides the dust and impurities.
