Description

Technical Field

[0001] The present invention relates to the technical field of aluminum foil film thickness detection, in particular to a device for detecting uniformity of aluminum foil insulation coating. Background Art

[0002] The uniformity of aluminum foil insulation coating is directly related to the insulation performance of aluminum foil. The current aluminum foil coating thickness detection device generally installs a thickness gauge on the rack during non-destructive testing on the production line. The thickness gauge has a limited coverage range of the aluminum foil strip and cannot perform tensile testing on the aluminum foil strip. The slack of the aluminum foil strip will cause an error in the distance between it and the thickness gauge, thereby affecting the accuracy of the detection. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an aluminum foil insulation coating uniformity detection device, thereby solving the problems of the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A device for detecting uniformity of aluminum foil insulation coatings includes a frame, one side of the frame being rotatably connected to a winding roller, the other side of the frame being rotatably connected to two guide rollers, the upper side of the frame being slidably connected to a slide, the slide being driven by a driving device to slide along the winding direction of the aluminum foil strip, one side of the slide being fixedly connected to a cross plate, the cross plate being slidably connected to a slide, and the slide being fixedly connected to a paint film thickness detector;

[0006] The bottom of the horizontal plate is fixedly connected to the suspension rod, the lower end of the suspension rod is fixedly connected to the horizontal rod, the upper side of the horizontal rod is slidably connected to the base, and the base is symmetrically connected to two adsorption boxes. The two adsorption boxes adsorb the aluminum foil strips with air pressure and rotate symmetrically. The two adsorption boxes adsorb the stretched aluminum foil strips and cooperate with the paint film thickness detector for detection.

[0007] Preferably, both ends of the guide roller are fixedly connected to tapered rollers.

[0008] Preferably, the upper side of the base is vertically slidably connected to the lifting seat, and the lifting seat is rotatably connected to two adsorption boxes. The rotating shaft of each adsorption box is fixedly connected to a first gear, and the two first gears are meshed with each other. One side of the base is fixedly connected to the rack, and one of the first gears is fixedly connected to the second gear, and the second gear is meshed with the rack.

[0009] Preferably, the base has a sliding hole on the upper side, in which a lifting rod is slidably connected, and the upper end of the lifting rod is fixedly connected to the lifting seat. A through groove is provided on the side of the base, in which a lifting rod is slidably connected, and a reset spring is fixedly connected between the lifting rod and the inner wall of the upper end of the through groove.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Example 1

[0020] like Figures 1 to 5 As shown, the present invention provides an aluminum foil insulation coating uniformity detection device, including a frame 1, one side of the frame 1 is rotatably connected to a winding roller 11, one side of the frame 1 is rotatably connected to two guide rollers 12, both ends of the guide roller 12 are fixedly connected to tapered rollers 13, the winding roller 11 is installed on a lifter, the winding roller 11 descends to adapt to the increase in the diameter of the aluminum foil strip 10 after winding, and always keeps the top of the aluminum foil strip 10 parallel to the top of the guide roller 12 after winding, and the aluminum foil strip 10 is attached to the tapered roller 13. When the aluminum foil strip 10 deviates, the tapered roller 13 plays a role of limiting (the edge of the aluminum foil strip 10 is equivalent to the uphill force that needs to be overcome on the tapered surface of the tapered roller 13). The upper side of the frame 1 is slidably connected to the slide 14, which is driven by a conventional linear motion drive device to slide along the winding direction of the aluminum foil strip 10, and the sliding speed of the slide 14 is the same as the transmission speed of the aluminum foil strip 10. One side of the slide 14 is fixedly connected to the cross plate 15, the cross plate 15 is slidably connected to the slider 16, and the slider 16 is fixedly connected to the paint film thickness detector 17;

[0021] The bottom of the horizontal plate 15 is fixedly connected to the suspension rod 18, the lower end of the suspension rod 18 is fixedly connected to the horizontal bar 2, the upper side of the horizontal bar 2 is slidably connected to the base 3, and the two adsorption boxes 4 are symmetrically rotated on the base 3. The two adsorption boxes 4 adsorb the aluminum foil strip 10 with air pressure and rotate symmetrically. The two adsorption boxes 4 adsorb the stretched aluminum foil strip 10 and cooperate with the paint film thickness detector 17 for detection. One side of the suspension rod 18 is fixedly connected to the air pump 5, and a hose 51 is fixedly connected between the air pump 5 and the adsorption box 4.

[0022] The present invention sets an adsorption box 4 at the bottom of the conveyed aluminum foil strip 10, and the sliding speed of the slide 14 is synchronized with the aluminum foil strip 10. The two adsorption boxes 4 are adsorbed at different positions on the bottom of the aluminum foil strip 10, and the base 3 below the adsorption box 4 slides back and forth along the cross bar 2 to correct the deviation of the aluminum foil strip 10. That is, the two adsorption boxes 4 are as follows. Figure 5 The two suction boxes 4 form a pulling force at the bottom of the aluminum foil strip 10, and the conical roller 13 plays a role of limiting. Therefore, the two suction boxes 4 are pulled toward the frame 1 and then pulled away from the frame 1, and the sliding friction force plays a role of correcting the deviation (due to the sliding friction force, when the aluminum foil strip 10 is not offset, the conical surface resistance of the conical roller 13 at both ends of the aluminum foil strip 10 is the same, so it will not cause the aluminum foil strip 10 to slip. After the aluminum foil strip 10 is offset, one end of the aluminum foil strip 10 is located on the surface of the guide roller 12 and separates from the conical roller 13 on one side. At this time, the aluminum foil strip 10 will be pulled by the winding roller 11 and stick to the suction box 4. Therefore, when the sliding friction force pushes the aluminum foil strip 10 to the side where the resistance is lacking, the aluminum foil strip 10 can be reset). At the same time, when correcting the deviation of the aluminum foil strip 10, as shown in FIG. Figure 5As shown, the aluminum foil strip 10 above the two adsorption boxes 4 is stabilized by tension, which on the one hand enables the paint film thickness detector 17 to detect accurately, and on the other hand can straighten different positions on the surface of the aluminum foil strip 10, thereby playing a role in uniformity detection.

[0023] Example 2

[0024] like Figures 1 to 5 As shown, the upper side of the base 3 is vertically slidably connected to the lifting base 31, and the lifting base 31 is rotatably connected to the two adsorption boxes 4. The rotating shaft of each adsorption box 4 is fixedly connected to a first gear 32, and the two first gears 32 are meshed with each other. One side of the base 3 is fixedly connected to the rack 33, and one of the first gears 32 is fixedly connected to the second gear 34, and the second gear 34 is meshed with the rack 33.

[0025] When the lifting seat 31 rises, the second gear 34 is limited by the rack 33, and the adsorption box 4 is Figure 4 Status changes to Figure 5 State, carry out paint film thickness detection, Figure 5 After the state, the adsorption box 4 performs vacuum adsorption, and the lifting seat 31 descends with the aluminum foil strip 10 partially concave downward, so that the edges on both sides of the aluminum foil strip 10 are gathered toward the guide roller 12. After the edges on both sides of the aluminum foil strip 10 are gathered to the guide roller 12, the vacuum effect is removed, and the aluminum foil strip 10 is unfolded again. At this time, the edges on both sides of the aluminum foil strip 10 need to overcome the resistance and slide toward the conical surface of the conical roller 13. The greater the sliding distance, the greater the resistance. Therefore, the edges on both sides of the aluminum foil strip 10 will be balanced, thereby playing a role in secondary correction.

[0026] There is a sliding hole on the upper side of the base 3, in which the lifting rod 4 is slidably connected. The upper end of the lifting rod 4 is fixedly connected to the lifting seat 31. A through slot 41 is provided on the side of the base 3, in which the lifting rod 42 is slidably connected. A return spring 43 is fixedly connected between the lifting rod 42 and the inner wall of the upper end of the through slot 41. Two arc-shaped protrusions 44 are fixedly connected to one side of the frame 1. An arc guide groove 45 is provided on the arc surface of the upper side of the arc protrusion 44. One end of the lifting rod 42 is rotatably connected to a roller 46. The roller 46 and the arc guide groove 45 are arranged correspondingly, and the arc guide grooves 45 of the two arc protrusions 44 are arranged oppositely.

[0027] The lifting of the lifting seat 31 is formed by the cooperation of the roller 46 at the end of the lifting rod 42 with the arc-shaped protrusion 44 and the arc-shaped guide groove 45. The roller 46 rolls into the arc-shaped guide groove 45 and is guided and limited by the arc-shaped guide groove 45, so that the lifting rod 4 rises and the base 3 moves horizontally along the cross bar 2. The entrances at both ends of the arc-shaped guide groove 45 are located on the same parallel line. After the aluminum foil strip 10 is moved by the adsorption box 4, it can return to its original position. The force of moving the aluminum foil strip 10 is small, and the edge of the aluminum foil strip 10 will not form defects such as wrinkles and jaggedness.

[0028] The U-shaped connecting rod 6 is fixedly connected between the slider 16 and the base 3, so that the support positions of the two adsorption boxes 4 and the position of the paint film thickness detector 17 move synchronously, thereby adapting to the tension detection on the aluminum foil strip 10 until it stops moving.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
