Description

Technical Field

[0001] The invention relates to the field of corrosion resistance detection device processing, and in particular to a corrosion resistance detection device and a detection method for automobile decorative strips. Background Art

[0002] Decorative strips are decorative accessories with decorative effects. Decorative strips on cars are generally set on the side of the car body, and they are highly consistent with the curvature of the car body. Existing car decorative strips are usually made of plastic bodies, which makes their installation difficult. Since the car body sides and top windows have a certain hardness, and since the car decorative strips are exposed to the outside, they will be corroded by external rain, so the produced decorative strips need to be tested for corrosion resistance.

[0003] A corrosion resistance detection device for automobile radiator plates disclosed in the patent application with reference publication number CN217237680U comprises a base, a support frame is provided on one side above the base, a cylinder is provided on one side above the support frame, a lifting plate is fixedly connected to the output end of the cylinder, a slider is provided on one side above the lifting plate, a screw rod 1 is connected through the inside of the slider, a rotating disk is provided on the top of the screw rod 1, a positioning block is provided at the bottom of the screw rod 1, a screw rod 2 is provided on one side below the positioning block, one end of the screw rod 2 is embedded in the inside of the clamping seat, a water tank is provided on the top of the base, and an ultrasonic transmitter is fixedly connected inside the water tank. The utility model generates high-frequency vibration in the solvent by using an ultrasonic generator and an ultrasonic transmitter, so that the bubbles between the radiator plate and the solvent are broken or floated, so that the radiator plate can be fully in contact with the solvent, thereby improving the accuracy of the corrosion resistance detection of the radiator plate.

[0004] In the above scheme, the workpiece to be tested is placed in a solvent and immersed in a clamping manner. The position where the workpiece is clamped is often unable to directly contact the solvent, so the clamping position cannot be tested. However, if the workpiece is placed directly in the solvent, the workpiece can indeed be in contact with the solvent. However, as the workpiece settles, the bottom will contact the bottom of the box, so the ground cannot be in contact with the solvent for a long time, resulting in the inability to perform a comprehensive corrosion test on the workpiece; and after the test, a large amount of solvent will adhere to the surface of the workpiece. If it is left alone, the solvent will corrode other objects. If it is wiped, it will corrode the wiped objects.

[0005] Therefore, it is necessary to provide a corrosion resistance detection device and a detection method for automobile decorative strips to solve the above technical problems. Summary of the invention

[0042] like Figures 1 to 12 As shown, a corrosion resistance detection device for automobile decorative strips includes the following embodiments:

[0043] like Figures 1 to 5 As shown, embodiment 1 includes:

[0044] A mobile cabinet 1, a support frame 3 is fixedly connected to the top of the mobile cabinet 1, a sliding module 4 is fixedly connected to the top of the support frame 3, a first hydraulic telescopic rod 401 is fixedly connected to the moving end of the sliding module 4, a fixed frame 5 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 401, a corrosion box 2 for containing corrosion liquid is arranged below the fixed frame 5, and the corrosion box 2 is fixedly connected to the top of the mobile cabinet 1;

[0045] The fixed frame 5 has second hydraulic telescopic rods 6 fixedly connected to both sides thereof, and the telescopic ends of the two second hydraulic telescopic rods 6 are fixedly connected to first movable plates 601, and the two first movable plates 601 are internally rotatably connected to clamping rollers 602 for clamping the decorative strips. The bottom of the fixed frame 5 is provided with a transmission assembly for driving the two clamping rollers 602 to rotate and push the decorative strips to move forward and backward inside the corrosion box 2;

[0046] The support frame 3 is fixedly connected to the third hydraulic telescopic rod 9 on both sides, and the telescopic ends of the two third hydraulic telescopic rods 9 are fixedly connected to the connecting frame 800. The two connecting frames 800 are fixedly connected to one side with a semi-circular frame 8, and the two semi-circular frames 8 are arranged opposite to each other. Cleaning components are arranged inside the two semi-circular frames 8 for removing corrosive liquid on the surface of the decorative strip.

[0047] In specific implementation, in the actual detection process, the decorative strip is often clamped and placed in the corrosion liquid, so that the decorative strip is taken out after the corrosion is completed. However, during the immersion process of the clamped decorative strip, the decorative strip at the clamping position of the clamp cannot fully contact with the corrosion liquid, resulting in the inability to perform corrosion detection. Then, by starting the two second hydraulic telescopic rods 6 on the inner side of the fixed frame 5, the clamping rollers 602 on the two first movable plates 601 clamp the automobile decorative strip, and then the fixed frame 5 is driven to move by the sliding module 4 to move the automobile decorative strip to the top of the corrosion box 2; then, by starting the first hydraulic telescopic rod 401, the clamped automobile decorative strip is immersed in the corrosion box 2, and the transmission assembly is started to move the automobile decorative strip back and forth between the two clamping rollers 602, so as to avoid the clamping point from being unable to be corroded and improve the contact effect.

[0048] like Figure 8 As shown, in this embodiment, the transmission assembly includes a transmission rod 603 fixedly connected to the top of the clamping roller 602, the transmission rod 603 passes through the first movable plate 601 and is rotatably connected to the first movable plate 601, the bottom of the fixed frame 5 is fixedly connected to a mounting plate 604, the top of the mounting plate 604 is provided with a moving frame 609, the inside of the moving frame 609 is rotatably connected to a second pulley 6012, the top of the moving frame 609 is fixedly connected to a first motor 6010, the output shaft of the first motor 6010 is fixedly connected to the second pulley 6012, and an elastic member is fixedly connected between the moving frame 609 and the mounting plate 604.

[0049] The transmission assembly also includes a third pulley 6013 fixedly connected to the top of one of the transmission rods 603, a second gear 606 fixedly connected to the top of the other transmission rod 603, the first gear 605 is meshedly connected to the outer side of the second gear 606, and a first pulley 607 is fixedly connected to the top of the first gear 605. A transmission belt is arranged between the first pulley 607, the third pulley 6013 and the second pulley 6012, and they are connected through the transmission belt.

[0050] The elastic member includes a telescopic rod 608 fixedly connected between the mounting plate 604 and the moving frame 609 , a spring 6011 is sleeved on the outer side of the telescopic rod 608 , and two ends of the spring 6011 are fixedly connected to the mounting plate 604 and the moving frame 609 respectively.

[0051] An ultrasonic transmitting device and an ultrasonic generator are installed inside the corrosion box 2.

[0052] In specific implementation, when the two clamping rollers 602 clamp the decorative strips and place them inside the corrosion box 2, by starting the first motor 6010, the output shaft of the first motor 6010 drives the moving frame 609 to rotate, and when the moving frame 609 is driven by the outer transmission belt, the third pulley 6013 and the first pulley 607 are driven to rotate synchronously. At this time, the third pulley 6013 drives one of the clamping rollers 602 to rotate through the transmission rod 603, and the other first pulley 607 drives the first gear 605 to rotate, and the first gear 605 drives the meshing connected second gear 606 to rotate, and then The transmission rod 603 drives the other clamping roller 602 to rotate, so that the two clamping rollers 602 simultaneously push the decorative strip clamped therebetween to move, and the decorative strip is driven to move back and forth inside the corrosion box 2 by the output shaft of the first motor 6010 rotating forward and reversely, and the contact position between the clamping roller 602 and the decorative strip is continuously changed, so as to prevent the clamping roller 602 from affecting the corrosion of the decorative strip by the etching liquid, and also improve the contact effect between the etching liquid and the decorative strip by driving the decorative strip to move back and forth, and start the ultrasonic transmitting device and the ultrasonic generator inside the corrosion box 2 to improve the contact between the etching liquid and the decorative strip.

[0053] When the two first movable plates 601 move away from or closer to each other, the spring 6011 in the elastic member and the telescopic rod 608 drive the movable frame 609 to move, and the transmission belt is tensioned to ensure the rotation effect of the two clamping rollers 602.

[0054] like Figures 5 to 7 As shown, embodiment 2; a lifting plate 701 is provided on the outer side of the two first movable plates 601, a screw rod 703 is provided on one side of the first movable plate 601, the screw rod 703 penetrates the lifting plate 701 and is rotatably connected to the lifting plate 701, a support plate 706 is rotatably connected to the outer side of the lifting plate 701, the support plate 706 is fixedly connected to the first movable plate 601, a second motor 704 is fixedly connected to the outer side of the first movable plate 601, the output shaft of the second motor 704 is fixedly connected to the screw rod 703, and auxiliary wheels 702 are rotatably connected inside the two lifting plates 701.

[0055] A deflection plate 707 is provided at the bottom of the lifting plate 701, and rotating shafts 7076 are fixedly connected on both sides of the deflection plate 707. The rotating shafts 7076 penetrate the lifting plate 701 and are rotatably connected to the lifting plate 701. A fixed cylinder 7075 is provided on the outer side of the rotating shaft 7076. The fixed cylinder 7075 is fixedly connected to the lifting plate 701, and a torsion spring 7077 is fixedly connected between the fixed cylinder 7075 and the rotating shaft 7076. One end of the deflection plate 707 is rotatably connected to a lower supporting wheel 7071, and the other end of the deflection plate 707 is fixedly connected to a wire rope 7073. A winding device 7074 is fixedly connected to the outer side of the first movable plate 601. The winding roller of the winding device 7074 is wound and fixed with the wire rope 7073. A guide wheel 7072 for guiding the wire rope 7073 is fixedly connected to the outer side of the lifting plate 701.

[0056] In specific implementation, when the two clamping rollers 602 clamp the decorative strip, if the decorative strip is heavy, it is easy to slip and the stability of the decorative strip during movement cannot be guaranteed. Therefore, in this solution, a lifting plate 701 is arranged on the outside of the first moving plate 601. When the clamping roller 602 contacts the decorative strip, the auxiliary wheel 702 on the lifting plate 701 contacts the decorative strip at the same time, thereby improving the stability of the decorative strip during movement. In addition, for decorative strips of different widths, by starting the second motor 704, the output shaft of the second motor 704 drives the screw rod 703 to rotate, and the screw rod 703 rotates to drive the lifting plate 701 to rise and fall, thereby achieving the goal of fixing different widths of decorative strips. Decorative strips of the same size are adjusted, and in order to ensure that the decorative strips do not fall, a deflection plate 707 is set at the bottom of the lifting plate 701, and the winding device 7074 is started to wind up, so that the wire rope 7073 on the winding roller of the winding device 7074 is wound up, and then the rotating support shaft 7076 on the deflection plate 707 is pulled to rotate, so that the lower support wheel 7071 at one end of the deflection plate 707 is rotated to make it contact with the bottom of the decorative strip, thereby ensuring the support of the decorative strip. When the decorative strip needs to be lowered later, the wire rope 7073 is loosened, and the deflection plate 707 is rotated and reset by the action of the torsion spring 7077.

[0059] In specific implementation, after the decorative strip has completed the corrosion immersion, the first hydraulic telescopic rod 401 rises and then drives the clamped decorative strip through the sliding module 4 to move to the position of the semi-annular frame 8. At this time, the third hydraulic telescopic rod 9 is started to align the two semi-annular frames 8, and the rotating annular frames 801 inside the two semi-annular frames 8 are aligned to make them connected. In order to ensure the sealing of the connection between the two rotating annular frames 801, a sealing sleeve can also be provided at the butt joint, and then one end of the decorative strip is pushed through the two semi-annular frames 8 through the transmission assembly.
