[0037] In order to be able to perform detection at any position and improve the flexibility of the detection position, as a specific embodiment of a flatness detection device for polytetrafluoroethylene materials provided by the present invention, please refer to Figures 1 to 5 , the flatness detection device for polytetrafluoroethylene materials further includes a mobile vehicle 50. The placement platform 10 and the detection mechanism 20 are both arranged on the mobile vehicle 50 and can be moved to any location by means of the mobile vehicle 50 for flatness detection.

There is also a display on the controller 40, and the remote controller 60 and the controller 40 can display information synchronously.

[0040] In order to enable the detection end 21 to slide and perform detection during sliding, as a specific implementation manner of a flatness detection device for polytetrafluoroethylene material provided by the present invention, please refer to Figures 1 to 5 , the detection mechanism 20 includes a lower slide rail 22 arranged below the placement platform 10 and parallel to the length direction of the placement platform 10, an upper slide rail 23 arranged above the placement platform 10 and parallel to the length direction of the placement platform 10, and a driver 24 arranged on the lower slide rail 22 and the upper slide rail 23. The power output end of the driver 24 is connected to the detection end 21 and is used to drive the detection end 21 to slide. The upper end of the detection end 21 is slidably connected to the upper slide rail 23, and the lower end is slidably connected to the lower slide rail 22. Both the upper slide rail 23 and the lower slide rail 22 are in two groups and are arranged in parallel. By driving the detection end 21 to move through the driver 24, detection can be performed during movement.

[0041] Specifically, there are at least two groups of the drivers 24 in this embodiment, and one group is arranged on each of the upper slide rail 23 and the lower slide rail 22. It includes a driving motor 241, a plurality of pulleys 242 arranged on the upper slide rail 23 or the lower slide rail 22, and a conveyor belt 243 wound around the plurality of pulleys 242. The power output end of the driving motor 241 is connected to the conveyor belt 243 and can drive the conveyor belt 243 to rotate. The upper end and the lower end of the detection end 21 are both slidably connected to the upper slide rail 23 or the lower slide rail 22, and the conveyor belt 243 is also connected to the detection end 21. Thus, the technical effect of driving the detection end 21 to translate can be achieved during the rotation of the conveyor belt 243. The conveyor belt 243 encloses a long rectangular structure. The driving motor 241 can be arranged on the bracket 52 of the mobile vehicle 50, or can also be arranged on the upper slide rail 23 or the lower slide rail 22.

[0042] As a specific implementation manner of a flatness detection device for polytetrafluoroethylene material provided by the present invention, please refer to Figures 1 to 5, the detection end 21 includes two sets of sliding rods 211 arranged vertically, which are respectively located on both sides of the placement platform 10. The upper and lower ends are respectively slidably connected to the upper slide rail 23 and the lower slide rail 22. The two sets of sliding rods 211 move simultaneously and are both provided with chutes 212 on the inner sides. A plurality of screw holes are equidistantly arranged along the height direction on the outer sides of the sliding rods 211. The axial direction of the screw holes is along the horizontal direction and penetrates through the chutes 212. Screws 213 are screwed into the through holes. A slider 214 is slidably connected in the chute 212. Screwing the screw 213 is used to abut against and limit the slider 214. Two sets of sliders 214 are connected with a pair of photoelectric sensors 215. The two sets of pair of photoelectric sensors 215 form a pair and are used to detect the flatness of the surface of the polytetrafluoroethylene product. The output end of the pair of photoelectric sensors 215 is electrically connected to the input end of the signal processor 30. Figure 3 The rectangular dotted line frame in it represents the product. The position of the pair of photoelectric sensors 215 on the sliding rod 211 can be adjusted, so as to meet the detection of the flatness of products with different thicknesses. After the upper surface of the product is detected, the product is placed upside down, and then the flatness of the lower surface is continuously detected. The clamping part 11 can clamp the product to ensure that the product will not slip, etc., so as to improve the accuracy of the flatness detection of the product. In order to enable the pair of photoelectric sensors 215 to slide along the chute 212, after the position is determined, the screw 213 is passed through the screw hole at the appropriate position, and the slider 214 is abutted by the screw 213. At this time, the slider 214 is fixed, so that the height of the slider 214 or the pair of photoelectric sensors 215 can be locked.

[0043] Specifically, one set of sliding rods 211 is correspondingly connected to one set of upper slide rails 23 and one set of lower slide rails 22. The sliding rods 211 can slide on the two sets of slide rails. In Figure 2 , the two sets of upper slide rails 23 or the two sets of lower slide rails 22 are connected by a connecting rod 216 to form an integral structure, so as to improve the stability of the detection end 21 during the translation process and ensure the accuracy of the flatness detection.

[0044] According to the operating principle of the opposed photoelectric sensor 215, it includes two groups of sensors. One group of sensors is arranged on one group of sliders 214, and the other group of sensors is arranged on the other group of sliders 214. The two groups of sensors constitute the opposed photoelectric sensor 215. One of the sensors is the transmitting end, which can emit red light or infrared light, and the other sensor is the receiving end, which can receive the signal emitted by the transmitting end. The two sensors are in the same horizontal plane, and the emitted light is exactly located above the product to be measured without contacting the product. When the product passes through and cuts off the light, a signal is output. That is, when the upper surface of the product is uneven, the light of the sensor is cut off at this time, and the sensor sends a signal to the signal processor 30. The signal processor 30 then analyzes and determines that there is an uneven phenomenon at this place on the product. When the light of the opposed photoelectric sensor 215 is not cut off during the movement process, it is considered that the upper surface of the product is not uneven, that is, it is a qualified product. At this time, the product should be placed upside down, and the flatness of the other surface of the product should be detected again in the same way as described above.

[0045] As a specific implementation manner of the flatness detection device for polytetrafluoroethylene materials provided by the present invention, please refer to Figures 1 to 5 , a telescopic bracket 217 is arranged at the upper end of the opposed photoelectric sensor 215. The telescopic bracket 217 is connected to a machine vision detection component 70. The machine vision detection component 70 is used to collect image information of the polytetrafluoroethylene product (from top to bottom). The machine vision detection component 70 is electrically connected to the controller 40, and the controller 40 is used to control the operation of the machine vision detection component 70. By using the machine vision detection component 70 to take an image of the upper surface of the product from top to bottom, while detecting the flatness of the product, it is possible to detect the appearance quality of the product, or detect whether there are defects. If there are defects, the detection should be stopped, or the positions with defects on the product should be marked for later processing. This embodiment solves the technical problem that the appearance quality defects of the product cannot be detected while detecting the flatness of the product.

[0046] The telescopic bracket 217 in this embodiment can be adjusted in the horizontal direction and can also be adjusted in the height direction, achieving the technical effect that the machine vision detection component 70 can adjust the shooting position of the product at different heights and different horizontal positions. The specific structure of the telescopic bracket 217 can select existing technical products and will not be limited here.

The machine vision detection component 70 is arranged at the end of the telescopic bracket 217 and includes a box body 72 and a plurality of detection rods 73 hinged to the outer side surface of the box body 72. There are multiple CCD cameras 71 evenly spaced on the plurality of detection rods 73. When the detection rods 73 rotate, the positions photographed by the CCD cameras 71 are also adjusted accordingly, so that images of multiple positions on the product can be comprehensively photographed. In this embodiment, the positions of the multiple detection rods 73 can be flexibly adjusted. The machine vision detection processor 74 is arranged inside the box body 72. The machine vision detection processor 74 (selecting a product in the prior art) includes multiple product images with appearance quality defects (i.e., image sets, which can be preset and can be increased or decreased), and also has machine vision detection software, which can compare the collected images with the stored images and output the comparison results for judging whether the appearance quality of the product is defective.

[0048] The product referred to in the present invention is a product made of polytetrafluoroethylene material, such as a plate-shaped product. When detecting a strip-shaped product, the product needs to be unfolded before detection.

[0049] As a specific implementation manner of a polytetrafluoroethylene material flatness detection device provided by the present invention, please refer to Figures 1 to 5 , the placement platform 10 includes a plurality of lifting columns 12 and a support plate 13.

A plurality of clamping parts 11 are all connected to the support plate 13 and close to the ends. The clamping parts 11 have the freedom of lifting vertically and are used to squeeze and clamp the ends of the polytetrafluoroethylene product during lifting. The lifting columns 12 can be telescoped vertically, so that the height of the product can be adjusted. When the opposed photoelectric sensor 215 is inconvenient to adjust the height, the height of the product can be adjusted by the lifting columns 12. The support plate 13 plays a role in supporting the product. The lower end surface of the support plate 13 is slidably connected to the upper ends of the plurality of lifting columns 12, that is, the length of the support plate 13 can be adjusted to adapt to products of various different lengths or widths for flatness detection.

Preferably, the clamping part 11 includes a stud 111 screwed to the support plate 13 (vertically passing through the support plate 13), a telescopic rod 112 provided at the upper end of the stud 111 (the two are coaxially arranged), and a pressing plate 113 provided at the upper end of the telescopic rod 112. The pressing plate 113 is used to clamp the end of the product. The height of the pressing plate 113 can be roughly adjusted by the telescopic rod 112, and the height of the pressing plate 113 can be precisely adjusted by screwing the stud 111, so as to press and fix the product. The pressing plate 113 can be circular, rectangular or square, and its center is fixedly connected to the upper end of the telescopic rod 112. When the telescopic rod 112 rotates, the pressing plate 113 rotates accordingly, and at this time, it does not affect the pressing of the product.

[0051] Preferably, an anti-slip pad is provided on the lower end surface of the pressing plate 113, which can prevent the product from moving after contacting the product.
