Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile detection, and in particular to a surface flatness detection device for aluminum profiles used in new energy vehicles. Background Art

[0002] With the continuous development of society, more and more new energy vehicles have entered every household. After the production of aluminum profile plates used in new energy vehicles, in order to ensure the production quality of the vehicles, detection equipment is required to detect the flatness of the aluminum profiles;

[0003] In the existing aluminum profile surface flatness detection equipment, the clamping assembly enables the aluminum profile template to be placed between two clamping bars during use. After placement, the second motor is started to rotate the two tooth columns, and the rotation of the two tooth columns drives the two clamping bars to gradually approach to fix the aluminum profile template. When it is necessary to detect one side of the aluminum profile template after fixation, the servo motor can be started to rotate the U-shaped block, and the rotation of the U-shaped block drives the aluminum profile template to rotate. In this case, the user can extremely conveniently adjust the detection surface of the aluminum profile template;

[0004] However, during detection, first, the aluminum profile to be detected needs to be loaded onto the mounting plate for detection. After detection, the detected aluminum profile needs to be unloaded from the mounting plate, and then the aluminum profile to be detected is re-loaded to continue the detection. In this way, the loading and unloading time of the aluminum profile is not fully utilized, reducing the detection work efficiency. Therefore, there are areas for improvement.

By using the reciprocating movement of the lifting plate 8, it drives the extrusion wheel 49 to roll on both side surfaces of the aluminum profile. Through the extrusion of one end of the pressing rod 46 on the pressure sensor, the detection work of the surface flatness of the aluminum profile is realized.

[0038] See Figure 1 , Figure 2 , Figure 7 and Figure 8 , the conveying structure includes four rollers 16 rotatably connected between the inner walls of the front and rear sides of the conveying table 1.

Cooperating with the limiting groove 23, the aluminum profile can enter the middle of the flipping frame 5, so that during detection, the aluminum profile can be detected more thoroughly.

A rotating shaft 28 is rotatably connected between the front and rear inner walls of the second opening 27. A gear 30 is fixedly sleeved in the middle of each rotating shaft 28, and a clamping block 29 is fixedly sleeved at both ends of each rotating shaft 28. A second driving structure is provided between the rotating shaft 28 and the front inner wall of the conveying table 1;

[0042] The second driving structure includes a driving plate 32 arranged in the middle of each group of two rotating shafts 28. Teeth meshing with the gears 30 are arranged on both side surfaces of the driving plate 32. The bottom end of the driving plate 32 is movably inserted into a fixed cylinder 31. The bottom end of the fixed cylinder 31 is connected to the rotating column 4. A second through groove 33 is formed in the side surface of the fixed cylinder 31 away from the first annular disc 2. A second insertion rod 34 passing through the second through groove 33 is connected to the driving plate 32. A reinforcing plate 35 is fixedly sleeved on the second insertion rod 34. The reinforcing plate 35 is attached to the inner walls of both sides of the flipping frame 5. The second insertion rod 34 movably passes through the through hole 24 on the corresponding limiting plate 22. Two connecting rods 37 are connected to the front inner wall of the conveying table 1 near the middle. A second annular disc 36 is installed at one end of the two connecting rods 37. A second arc groove 38 is formed below one side of the second annular disc 36, and a third arc groove 39 is formed above one side surface of the second annular disc 36. The second arc groove 38 and the third arc groove 39 are connected by two connecting grooves 40. One ends of multiple second insertion rods 34 are respectively inserted into the second arc groove 38 and the third arc groove 39. When the aluminum profile enters the flipping frame 5, with the rotation of the flipping frame 5, the second insertion rod 34 is driven to slide from the second arc groove 38 and the connecting groove 40 to the third arc groove 39. By using the sliding of one end of the second insertion rod 34 in the third arc groove 39 and the connecting groove 40, the driving plate 32 can be driven to move towards the side close to the rotating column 4 in the fixed cylinder 31. The rotation of the rotating shaft 28 is driven by the gear 30 to drive the clamping block 29 to clamp and fix the aluminum profile in the flipping frame 5.

[0043] The implementation principle of the surface flatness detection device for aluminum profiles for new energy vehicles according to an embodiment of the present invention is as follows: first, the second motor 57 is started to drive the conveyor belt 58 to rotate, and the conveyor belt 58 on the left side conveys the aluminum profile to be detected to the flip frame 5. At the same time, the first motor 3 is started to drive the flip frame 5 of the rotating column 4 to rotate as a whole, and the flip frame 5 rotates the aluminum profile on the left conveyor belt 58. In the process of rotating, the flip frame 5 drives the first insertion rod 11 and the second insertion rod 34 to rotate synchronously. One end of the first insertion rod 11 slides from the first arc-shaped groove 12 to the transverse groove 13. By sliding the first insertion rod 11 in the transverse groove 13, the connecting bar 9 and the lifting plate 8 can be driven to move back and forth on the flip frame 5 as a whole, thereby driving the extrusion wheel 49 to roll on both sides of the aluminum profile. While the extrusion wheel 49 rolls, it drives one end of the extrusion rod 46 to squeeze the pressure sensor on the end block 44. If the pressure value is within a reasonable range, the surface flatness of the aluminum profile is qualified. , if the pressure value exceeds a reasonable range, the controller 14 controls the buzzer alarm light 15 to alarm, and the surface flatness of the aluminum profile is unqualified. After the inspection, the flip frame 5 drives the aluminum profile to be transferred to the right rotating conveyor belt 58 for unloading and conveying, so that the aluminum profile can be inspected while unloading and loading, and the unloading and loading time of the aluminum profile is reasonably utilized, thereby improving the inspection work efficiency. Moreover, when one end of the second insertion rod 34 slides in the connecting groove 40 and the third arc groove 39, the flip frame 5 can rotate the aluminum profile while driving the driving plate 32 to move in the fixed cylinder 31, and the gear 30 drives the clamping block 29 to rotate and clamp the aluminum profile, thereby avoiding the problem of the aluminum profile moving or even falling during the transfer and inspection of the aluminum profile. When the flip frame 5 drives the inspected aluminum profile to the conveyor belt 58 on the right, the clamping block 29 can be automatically released on the flip frame 5, so that the material can be unloaded smoothly, thus realizing the inspection of the aluminum profile.
