Description

Technical Field

[0001] The invention relates to the technical field of Teflon high-temperature cloth production, in particular to a detection device for Teflon high-temperature cloth production. Background Art

[0002] Teflon high temperature cloth is a high temperature resistant cloth made of Teflon material, which is particularly suitable for applications in high temperature environments because Teflon has excellent heat resistance and chemical resistance. Among them, Teflon high temperature adhesive tape is a type of Teflon high temperature cloth, which can be pasted on the desired surface in a high temperature environment to provide a good fixing effect. In the production process of Teflon high temperature adhesive tape, a variety of performance tests are required to ensure that the product meets the design requirements, including adhesion testing. The adhesion test of Teflon high temperature adhesive tape is mainly to place it under high temperature conditions and stick it on the board for a period of time, and then tear it off. During the process, observe whether there will be any Teflon high temperature adhesive tape residue on the board surface, and observe whether the Teflon high temperature adhesive tape is broken to measure whether the adhesion of the Teflon high temperature adhesive tape is qualified.

[0003] However, when testing the adhesion of Teflon high-temperature adhesive tape in a high-temperature environment, the Teflon high-temperature adhesive tape and the board surface to which it is pasted will be very high.

[0035] The lower surface of the pressing block 19 is arranged in an arc surface corresponding to the arc block 18 , and a plurality of protrusions 16 are fixedly connected to the lower surface of the pressing block 19 corresponding to the arc block 18 , and grooves 17 are respectively formed on the outer wall of the arc block 18 corresponding to the plurality of protrusions 16 .

[0037] In the present embodiment, the cloth body 2 is a Teflon high temperature adhesive tape. First, the cloth body 2 is pasted to the bottom end of the inner side of the concave frame 3 near the shovel blade 20. During the process, the cloth body 2 can be aligned with the rear end of the cloth body 2 and one of the linear grooves 1 by observing the multiple linear grooves 1. In addition, due to the multiple linear grooves 1, the cloth bodies 2 of different lengths can be assisted in being aligned, and their front ends are as close to the shovel blade 20 as possible. Subsequently, the cloth body 2 can be heated by a heating device such as a hot air blower so that the cloth body 2 is under high temperature conditions. By setting a transmission component, the L-shaped frame 6 can be driven to move forward, and the L-shaped frame 6 can drive the L-shaped plate 26, the shovel blade 20 and other components connected thereto to move forward together, and the shovel blade 20 can scoop up the end of the cloth body 2 (it should be noted that, under the cooperation of the plug plate 31 and the slot 32, the triangular block 27 will be restricted from moving backward, and the shovel blade 20 connected to the triangular block 27 will not be moved backward). As the shovel blade 20 continues to move forward, the cloth body 2 can be continuously scooped up and the scooped cloth body 2 will move upward along the arc surface of the arc block 18, and the scooped cloth body 2 will enter between the pressing block 19 and the arc block 18, until the L-shaped plate 26 contacts the scooped cloth body 2, and the multiple electric push rods 9 are started, and the multiple electric push rods 9 can drive the fixed plate 10 to move downward, and the fixed plate 10 can drive the multiple splicing columns 34 to move on the inner wall of the upper end of the L-shaped plate 26. The pressing block 19 slides downward, and the plurality of splicing columns 34 can drive the pressing block 19 to move downward until the pressing block 19 presses the scooped cloth 2 tightly against the arc block 18. Since the lower surface of the pressing block 19 is arranged in an arc surface corresponding to the arc block 18, and the plurality of protrusions 16 under the pressing block 19 at this time will respectively enter the plurality of grooves 17 on the arc block 18, the partially scooped cloth 2 can be firmly fixed to avoid slipping when the remaining cloth 2 is torn off later.

[0038] It should be noted that when the pressing block 19 moves downward, it can drive the slide plate 30 to slide down in the slide groove 33 on the L-shaped plate 26, and the slide plate 30 can drive the slot 32 at its upper end to move downward and disengage from the plug plate 31. As the slide plate 30 continues to move downward, the lower edge of the rear end of the slide plate 30 will continue to squeeze the inclined wall surface of the triangular block 27. During this process, the triangular block 27 will slide backward on the outer wall of the multiple connecting columns 28, and the triangular block 27 will stretch the multiple springs 29 connected to the L-shaped plate 26, and the triangular block 27 will drive the shovel blade 20 to move backward until the pressing block 19 moves downward to press the scooped cloth body 2.

[0039] Finally, the driving component can drive the L-shaped plate 26 to rotate counterclockwise, and the parts connected to the L-shaped plate 26 will rotate counterclockwise, so that the fixed scooped cloth 2 will be folded, and then the transmission component continues to control the L-shaped frame 6 to move forward, which can pull and tear the remaining pasted cloth 2. At this time, the shovel blade 20 will leave the scooped cloth 2 due to its backward movement, so that the shovel blade 20 is prevented from continuing to scoop up the cloth 2, thereby simulating manual tearing of the cloth 2, and there is no need to wait for the cloth 2 to cool down, and the end of the cloth 2 can be quickly uncovered and firmly fixed, which is easy to operate and improves the detection efficiency.

[0040] Example 2: Please refer to Figure 3-Figure 5 The present embodiment further explains Example 1. The limiting mechanism in the figure includes a limiting plate 14 and a plurality of fixed blocks 23. The limiting plate 14 is attached to the front end of the L-shaped plate 26. The plurality of fixed blocks 23 are fixedly connected in a linear array at the upper front edge of the L-shaped plate 26, and the upper ends of the plurality of fixed blocks 23 are fixedly connected with U-shaped tubes 24. Pull ropes 25 are slidably inserted into the interiors of the plurality of U-shaped tubes 24. One ends of the plurality of pull ropes 25 are fixedly connected to the lower front edge of the fixing plate 10, and the other ends of the plurality of pull ropes 25 are fixedly connected with the U-shaped block 21. The plurality of U-shaped blocks 21 are fixedly connected to the upper edge of the rear end of the limiting plate 14, and the lower ends of the plurality of U-shaped blocks 21 are fixedly connected with springs 22 respectively between the upper ends of the plurality of U-shaped tubes 24, and the plurality of springs 22 are slidably sleeved on the outer walls of the plurality of pull ropes 25. In this embodiment, when the shovel blade 20 is about to scoop up the cloth body 2, the lower end of the limiting plate 14 will first contact the front edge of the upper end of the cloth body 2. Then, when the shovel blade 20 scoops up the cloth body 2, under the action of the limiting plate 14, the cloth body 2 can be restricted from rolling away from the shovel blade 20, and the scooped cloth body 2 can be guided to enter between the pressing block 19 and the arc block 18, so that the scooped cloth body 2 can be more smoothly and firmly fixed by the pressing block 19 and the arc block 18.

[0041] When the electric push rod 9 drives the fixed plate 10 to move downward, the multiple springs 22 are in a compressed state. As the fixed plate 10 moves downward, the multiple springs 22 will push the U-shaped blocks 21 connected to them to move upward. The multiple U-shaped blocks 21 can drive the limiting plate 14 to slide upward at the front end of the L-shaped plate 26, and the pull rope 25 will slide inside the U-shaped tube 24, and the end of the pull rope 25 corresponding to the fixed plate 10 will gradually approach the upper end of the U-shaped tube 24, and the end of the pull rope 25 corresponding to the U-shaped block 21 will gradually move away from the upper end of the U-shaped tube 24, then the limiting plate 14 will move away from the upper surface of the cloth body 2. At this time, when the L-shaped plate 26 is driven to rotate by the driving assembly, the limiting plate 14 will also rotate accordingly, and at this time, the bottom end of the limiting plate 14 will not squeeze the upper surface of the cloth body 2, thereby avoiding the rotation of the L-shaped plate 26 being restricted by the limiting plate 14. It should be noted that when the shovel blade 20 moves back to the extreme position, the lower edge of its front end corresponds to the rotation point where the driving assembly drives the L-shaped plate 26 to rotate, so the shovel blade 20 can rotate smoothly without being hindered by the inner bottom surface of the concave frame 3.
