Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a CCD vision assembly precision testing machine for new energy vehicle connector processing. Background Technology

[0002] Connectors in new energy vehicles are key connection components for batteries, motors, and electronic control systems. Their assembly accuracy (such as pin position deviation, interface alignment accuracy, and solder joint flatness) directly affects the overall electrical performance and safety of the vehicle. However, current inspection technologies rely primarily on manual inspection, depending on operator visual observation or simple measuring tools. This is inefficient, and the accuracy is greatly affected by human factors, making it difficult to meet the demands of mass production. Therefore, those skilled in the art have provided a CCD vision assembly accuracy inspection machine for new energy vehicle connector processing to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a CCD vision assembly precision inspection machine for the processing of connectors for new energy vehicles, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A CCD vision assembly precision inspection machine for new energy vehicle connector processing includes a processing table, an inspection frame, a lateral adjustment motor box, a hydraulic cylinder, and an inspection machine angle flipping motor. The inspection frame is welded and fixedly connected between the left and right sides of the top of the processing table. The lateral adjustment motor box is bolted and fixedly connected to the right side of the top of the inspection frame. The inner wall surfaces of the lateral openings at both ends of the inspection frame are frictionally and rollingly connected to the lateral adjustment driven screw. The outer wall surface of the lateral adjustment driven screw is slidably connected to the lateral sliding thread bearing. A support plate is welded and fixedly connected to the middle of the outer side of the lateral sliding thread bearing. A hydraulic cylinder is welded and fixedly connected to the inner wall surface of the top center of the support plate. A piston is slidably connected to the piston hydraulic rod on the inner wall surface of the hydraulic cylinder. A flipping motor positioning block and a flipping shaft positioning block are welded and fixedly connected to the middle of the bottom end of the piston hydraulic rod. The inspection machine angle flipping motor is bolted and fixedly connected to the middle of the front end of the flipping motor positioning block. The output shaft of the inspection machine angle flipping motor is rotatably connected to the flipping shaft through the inner wall surface. A fixing sleeve is engaged and fixedly connected to the middle of the outer wall surface of the flipping shaft. The inspection machine is welded and fixedly connected to the middle of the bottom end of the fixing sleeve.

[0006] As a further embodiment of this utility model: an oil storage bottle is welded and fixedly connected to the middle of the top of the hydraulic cylinder, and an oil extraction pipe is fixedly connected to the left and right ends of the oil storage bottle at the front and rear sides.

[0007] As a further improvement of this utility model, the oil pump and the check valve are sequentially and fixedly connected at the penetration point on the outer wall surface of the oil extraction pipe.

[0008] As a further embodiment of this utility model: the horizontal adjustment motor is fixedly connected to the front left side of the inner left end of the horizontal adjustment motor box by bolts, and the output shaft of the inner wall surface of the horizontal adjustment motor is rotatably connected to the rotating drive shaft.

[0009] As a further embodiment of this utility model: the right side of the outer wall surface of the rotating drive shaft is welded and fixedly connected to the drive gear inside the transverse adjustment motor box, and the gear on the lower side of the outer wall surface of the drive gear is engaged and rolled to connect to the transmission gear.

[0010] As a further embodiment of this utility model: the inner wall surface of the transmission gear is welded and fixedly connected to the transmission gear shaft, and the left and right sides of the outer wall surface of the transmission gear are meshed and rotatably connected to the driven gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Adjust the height, angle, and lateral direction of the testing machine according to the connector model. Start the lateral adjustment motor, hydraulic cylinder oil pump, and testing machine angle tilting motor inside the lateral adjustment motor box. The output shaft on the inner wall surface of the lateral adjustment motor drives the rotating drive shaft to rotate through the coupling. The drive gear is installed on the right side of the outer wall surface of the rotating drive shaft inside the lateral adjustment motor box. The transmission gear is located below the outer wall surface of the drive gear, and the driven gear is located on the left and right sides of the outer wall surface of the transmission gear. The power of the lateral adjustment motor is transmitted to the drive gear through the rotating drive shaft. The drive gear drives the transmission gear and the driven gear to rotate sequentially. The lateral adjustment driven screw is welded to the inner wall of the driven gear. The inner wall surface of the transversely chiseled section at both ends of the inspection frame is used for transverse adjustment. The driven screw rotates with the driven gear, and the transverse sliding threaded bearing is fitted onto the threaded engagement point on the outer wall surface of the driven screw. The transverse sliding threaded bearing converts the rotational force of the driven screw into the transverse linear motion of the support plate. The transverse adjustment adopts a gear transmission and precision screw structure, combined with the zero-backlash engagement of the transverse sliding threaded bearing, achieving a transverse positioning accuracy of ±0.01mm. This ensures that the inspection machine accurately aligns with connector feature areas such as pin spacing and pin position. The gear transmission adjustment process requires no manual intervention and can continuously inspect ≥1000 pieces / hour, meeting the needs of mass production.

[0013] 2. The hydraulic cylinder is mounted on the outer middle of the transverse sliding threaded bearing via a support plate. Hydraulic oil is drawn from the oil reservoir by an oil pump. The oil inlet is opened by a check valve, and the oil is pumped into the hydraulic cylinder through the oil extraction pipe. The hydraulic oil pushes the piston rod inside the hydraulic cylinder to extend and retract, causing the main body of the inspection machine to rise and fall vertically within a range of 0-200mm until the CCD lens of the inspection machine maintains an optimal distance of 50-150mm between it and the connector inspection surface. After the height is adjusted to the correct position, the check valve is closed to lock the oil circuit. The piston rod remains in a stable position under the pressure of the hydraulic oil, ensuring no height drift during the inspection process. The hydraulic height adjustment is achieved by locking the oil circuit through the check valve. Combined with the rigid support of the piston rod, the height stability is ≤0.005mm / h, avoiding image blurring caused by height drift. The measurement accuracy can reach ±0.005mm, ensuring dimensional measurement accuracy. The hydraulic system has a start-up time of ≤0.5s, with a fast response speed. Combined with the PLC control system, it can achieve multi-axis linkage. The switching time for multi-area inspection of a single connector is ≤2s, which is more than 10 times more efficient than manual adjustment. Attached Figure Description

The top end of the hydraulic cylinder 7 is welded and fixedly connected to the oil storage bottle 15. The left and right ends of the oil storage bottle 15 are engaged and fixedly connected to the front and rear sides of the oil storage bottle 15 via oil suction pipes 16. The outer wall surface of the oil suction pipe 16 is... The oil pump 17 and the check valve 18 are sequentially and fixedly connected at the through-hole. The horizontal adjustment motor 19 is fixedly connected to the front left side of the interior of the horizontal adjustment motor box 3 by bolts. The output shaft of the inner wall surface of the horizontal adjustment motor 19 is rotatably connected to the rotating drive shaft 20.

The gears on the left and right sides of the outer wall surface of the transmission gear 22 are meshed and rotatably connected to the driven gear 24.

[0020] The working principle of this utility model is as follows: When using this utility model, firstly, the height, angle, and lateral direction of the testing machine 14 are adjusted according to the model of the connecting parts. Then, the lateral adjustment motor 19, the oil pump 17 of the hydraulic cylinder 7, and the angle-reversing motor 11 of the testing machine inside the lateral adjustment motor box 3 are started. The output shaft on the inner wall surface of the lateral adjustment motor 19 drives the rotating drive shaft 20 to rotate via a coupling. The drive gear 21 is installed on the right side of the outer wall surface of the rotating drive shaft 20 inside the lateral adjustment motor box 3. The transmission gear 22 is located below the outer wall surface of the drive gear 21, and the driven gear 24 is located on the left and right sides of the outer wall surface of the transmission gear 22. The lateral adjustment... The power of the motor 19 is transmitted to the drive gear 21 via the rotating drive shaft 20. The drive gear 21 drives the transmission gear 22 and the driven gear 24 to rotate sequentially. The lateral adjustment driven screw 4 is welded to the inner wall surface of the driven gear 24 and is located on the inner wall surface of the lateral excavation at both ends of the testing frame 2. The lateral adjustment driven screw 4 rotates with the driven gear 24. The lateral sliding threaded bearing 5 is sleeved on the threaded engagement point on the outer wall surface of the lateral adjustment driven screw 4.

The hydraulic cylinder 7 is installed at the middle of the outer side of the lateral sliding threaded bearing 5 via the support plate 6. The oil pump 17 draws hydraulic oil from the oil storage bottle 15. The check valve 18 opens the oil inlet, and the oil is pumped into the hydraulic cylinder 7 through the oil extraction pipe 16. The hydraulic oil pushes the piston hydraulic rod 8 in the hydraulic cylinder 7 to extend and retract, causing the main body of the testing machine to vertically rise and fall within a range of 0-200mm until the CCD lens of the testing machine 14 maintains the optimal distance of 50-150mm between it and the connector testing surface. After the height is adjusted to the correct position, the check valve 18 is closed to lock the oil circuit. The piston hydraulic rod 8 maintains a stable position under the pressure of the hydraulic oil, ensuring that the height does not drift during the testing process. Finally, the angle tilting motor 11 of the testing machine is fixed to the front end of the tilting motor positioning block 9 by bolts. The output shaft of the inspection machine angle flipping motor 11 drives the flipping shaft 12 to rotate through a coupling. The flipping shaft 12 rotates smoothly under the bearing support of the flipping shaft positioning block 10. The inspection machine 14 is installed on the outer surface of the flipping shaft 12 through the fixed sleeve 13, which drives the inspection machine 14 to rotate around the flipping shaft 12. The flipping angle range is ±90°, and the angle adjustment accuracy is ±0.1°. After the horizontal, height, and angle adjustments are completed, the CCD vision system starts the inspection. If it is necessary to switch the inspection area, the control system links the horizontal adjustment motor, hydraulic system, and flipping motor to automatically adjust the posture of the inspection machine according to the preset program, so as to realize continuous inspection of multiple parts such as the top surface, side, and pins of the connector.
