Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and specifically relates to a device for testing the flatness of double-sided conductive cloth. Background Technology

[0002] Double-sided conductive fabric is a functional material in which a conductive layer (such as a metal plating, conductive polymer, or carbon nanomaterial) is uniformly coated on both sides of a substrate (such as polyester fiber or PET film). It combines flexibility, conductivity, and electromagnetic shielding properties, and is widely used in flexible circuits, smart wearable devices, and electromagnetic shielding covers. After production, the surface flatness of double-sided conductive fabric needs to be inspected. This is because unevenness or wrinkles on the surface can lead to uneven conductive layer thickness or breakage, directly affecting conductivity stability and electromagnetic shielding effectiveness. Existing inspection methods for double-sided conductive fabric generally rely on manual inspection or measurement. While these methods are simple to operate, relying solely on manual experience for flatness inspection results in low efficiency and is only suitable for small-batch inspections, failing to meet the needs of large-scale inspections. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-sided conductive cloth flatness detection device to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a double-sided conductive cloth flatness detection device, comprising: a tension adjustment component and a detection component, wherein the tension adjustment component is installed on the top right side of the detection table, and the tension adjustment component includes a tension roller and a support plate;

[0005] A detection component is installed on the left side of the tension adjustment component. The detection component includes a fixed detection element and a movable detection element. Both the fixed detection element and the movable detection element are semi-cylindrical structures. The fixed detection element and the movable detection element have the same specifications and their curved surfaces are opposite each other.

[0006] In a preferred embodiment, an unwinding roller is installed on the right side of the detection component, and a take-up roller is installed on the left side of the detection component. The unwinding roller and the take-up roller have the same specifications.

[0007] In a preferred embodiment, an unwinding groove is provided on the outer side of the unwinding roller from front to back, and a winding groove is provided on the outer side of the winding roller from front to back, wherein the unwinding groove and the winding groove have the same specifications.

[0008] In a preferred embodiment, the tension adjustment assembly includes a support frame and a tension roller. The support frame has a C-shaped structure, and a pair of electric push rods are installed at the front and rear positions of the top of the support frame.

[0009] In a preferred embodiment, a roller cover is installed on the inner side of the support frame, and a tension roller is installed on the inner side of the roller cover. The top front and rear positions of the roller cover are respectively connected to the bottom output ends of two sets of electric push rods through two sets of push rods.

[0010] In a preferred embodiment, a support plate for supporting the double-sided conductive cloth is installed on the lower inner side of the support frame. The support plate is located directly below the tension roller, and a pressure sensor is installed inside the tension roller.

[0011] In a preferred embodiment, the detection assembly includes a support frame 2, a fixed detection component, and a movable detection component. Two sets of electric push rods 2 are installed at the front and rear positions of the top of the support frame 2. The bottom output end of the electric push rods 2 is fixed to the top of the movable detection component inside it through a pair of push rods 2.

[0012] In a preferred embodiment, a number of pressure sensors 2 are embedded in the bottom curved surface of the movable detection component from front to back, and a number of pressure sensors 3 are embedded in the top curved surface of the fixed detection component from front to back. The number of pressure sensors 2 and pressure sensors 3 are the same and their positions are opposite each other.

[0013] In a preferred embodiment, there is a detection gap between the movable detection component and the fixed detection component. The detection gap, the top of the support plate, and the lower surface of the winding roller are in the same horizontal plane. The rear side of the winding roller is driven by a drive motor.

[0014] The detection component is driven by a pair of moving mechanisms installed at the front and rear positions of the detection stage. The moving mechanisms include a sliding base and a guide rail.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a tension adjustment component and a detection component, the tension adjustment component includes a tension roller and a support plate, and the detection component includes a movable detection component and a fixed detection component. The tension roller applies pressure downward to the double-sided conductive cloth, thereby making the surface of the double-sided conductive cloth taut, which helps to improve the accuracy of the surface flatness detection of the double-sided conductive cloth. The double-sided conductive cloth passes between the movable detection component and the fixed detection component, and then the movable detection component moves down to slightly clamp the double-sided conductive cloth between the two. The moving mechanism drives the detection component to move left and right, so that the flatness of the upper and lower surfaces of the entire double-sided conductive cloth can be detected at the same time, thus greatly improving the detection efficiency and significantly improving the detection accuracy compared with manual detection.

[0016] 2. By setting up unwinding and rewinding rollers with the same specifications, a pair of unwinding grooves are opened on the outer side of the unwinding roller, and a pair of rewinding grooves are opened on the outer side of the rewinding roller. In actual use, rolls of double-sided conductive fabric can be placed on the outer side of both sets of unwinding grooves, and the pair of rewinding grooves can simultaneously rewind the double-sided conductive fabric wrapped on the outer side of the pair of unwinding grooves. During unwinding and rewinding, the detection components between the two can detect the flatness of the double-sided conductive fabric. Therefore, the unwinding, rewinding and detection processes are linked, which significantly improves the detection efficiency and can meet the requirements of large-scale detection.

[0028] Please see Figures 1 to 5 A double-sided conductive fabric flatness detection device includes: a tension adjustment component 200 and a detection component 300. The tension adjustment component 200 is installed on the top right side of the detection table 100. The tension adjustment component 200 includes a tension roller 211 and a support plate 212.

[0029] A detection component 300 is installed on the left side of the tension adjustment component 200. The detection component 300 includes a fixed detection component 310 and a movable detection component 320. Both the fixed detection component 310 and the movable detection component 320 are semi-cylindrical structures. The fixed detection component 310 and the movable detection component 320 have the same specifications and their curved surfaces are opposite each other.

[0030] An unwinding roller 110 is installed on the right side of the detection assembly 300, and a take-up roller 120 is installed on the left side of the detection assembly 300. The specifications of the unwinding roller 110 and the take-up roller 120 are exactly the same.

[0031] An unwinding groove 111 is provided on the outer side of the unwinding roller 110 from front to back, and a take-up groove 121 is provided on the outer side of the take-up roller 120 from front to back. The unwinding groove 111 and the take-up groove 121 have the same specifications.

[0032] The tension adjustment assembly 200 includes a support frame 1 and a tension roller 211. The support frame 1 has a C-shaped structure, and a pair of electric push rods 1 are installed at the front and rear positions of the top of the support frame 1.

[0033] A roller cover 210 is installed on the inner side of the support frame, and a tension roller 211 is installed on the inner side of the roller cover 210. The top front and rear positions of the roller cover 210 are respectively connected to the bottom output ends of two sets of electric push rods through two sets of push rods.

[0034] A support plate 212 for supporting the double-sided conductive cloth is installed on the lower inner side of the support frame. The support plate 212 is located directly below the tension roller 211. A pressure sensor is installed inside the tension roller 211.

[0035] The detection component 300 includes a support frame 2, a fixed detection component 310, and a movable detection component 320. Two sets of electric push rods 2 are installed at the front and rear positions of the top of the support frame 2. The bottom output end of the electric push rods 2 is fixed to the top of the movable detection component 320 inside it through a pair of push rods 2.

[0036] Several sets of pressure sensors 2 are embedded in the bottom curved surface of the active detection component 320 from front to back. Several sets of pressure sensors 3 are embedded in the top curved surface of the fixed detection component 310 from front to back. The number of pressure sensors 2 and pressure sensors 3 are the same and their positions are opposite each other.

[0037] There is a detection gap between the active detection component 320 and the fixed detection component 310. The detection gap, the top of the support plate 212 and the lower surface of the take-up roller 120 are in the same horizontal plane. The rear side of the take-up roller 120 is driven by a drive motor.

[0038] The detection component 300 is driven by a pair of moving mechanisms 400 installed at the front and rear positions of the detection stage 100. The moving mechanism 400 includes a sliding base and a guide rail.

[0039] Example 1: Please refer to Figures 1 to 5 In actual use, an unwinding roller 110 is installed on the far right of the top of the testing platform 100. A pair of unwinding grooves 111 of the same specification are opened on the outer side of the unwinding roller 110 from front to back. A take-up roller 120 of the same specification as the unwinding roller 110 is installed on the far left of the top of the testing platform 100. Two sets of take-up grooves 121 are opened on the outer side of the take-up roller 120 from front to back. The rear side of the take-up roller 120 is driven by a drive motor. A testing component 300 is installed on the right side of the take-up roller 120. The testing component 300 includes a fixed testing component 310 and a movable testing component 320. A support frame 2 is provided on the outer side of the fixed testing component 310 and the movable testing component 320. An electric push rod 2 is vertically installed at the front and rear positions of the top of the support frame 2. Each set of electric push rods 2 is fixed to the top of the movable testing component 320 on the inner side of the mounting frame by a push rod 2. Therefore, the movable testing component 320 can be moved closer to or away from the fixed testing component 310 by the push of the two sets of electric push rods 2.

[0040] Several sets of pressure sensors 2 are embedded in the bottom curved surface of the movable detection component 320 from front to back. Several sets of pressure sensors 3 are embedded in the top curved surface of the fixed detection component 310 from front to back. The number of pressure sensors 2 and 3 are the same and their positions are opposite each other vertically. The detection component 300 is driven to move left and right by two sets of moving mechanisms 400. A tension adjustment component 200 is installed on the right side of the detection component 300. The tension adjustment component 200 includes a support frame 1 and a tension roller 211. A roller cover 210 is installed inside the support frame 1. A tension roller 211 is installed inside the roller cover 210. The top front and rear positions of the roller cover 210 are connected to the bottom output ends of two sets of electric push rods through two sets of push rods. A support plate 212 for supporting the double-sided conductive cloth is installed on the lower inner side of the support frame. The support plate 212 is located directly below the tension roller 211. A pressure sensor is installed inside the tension roller 211. There is a detection gap between the movable detection element 320 and the fixed detection element 310. The detection gap, the top of the support plate 212, and the lower surface of the winding roller 120 are in the same horizontal plane.

[0041] In actual use, the double-sided conductive fabric roll is sleeved on the outside of the unwinding groove 111. One side of the double-sided conductive fabric passes through the gaps between the tension roller 211 and the support plate 212, and between the movable detection element 320 and the fixed detection element 310, and wraps around the outside of the take-up groove 121. At this time, the two sets of electric push rods can be activated first, so that the two sets of electric push rods push the tension roller 211 downward through the push rod, so that the bottom of the tension roller 211 slightly presses the double-sided conductive fabric against the top of the support plate 212. The specific pressure can be adjusted according to the specific application conditions. The feedback data from pressure sensor one is adjusted so that the double-sided conductive cloth is in a suitable flatness detection tension range. Then, two sets of electric push rods two are activated. The two sets of push rods two push the movable detection component 320 downward and close to the top of the fixed detection component 310, so that the double-sided conductive cloth is slightly clamped between the fixed detection component 310 and the movable detection component 320. (Electric push rod one, electric push rod two, moving mechanism 400 and drive motor are all existing technologies, and their internal structure and working principle will not be described in detail here.)

[0042] After preparation, the double-sided conductive cloth is stretched on the surface of the detection platform 100. Two sets of moving mechanisms 400 are activated, driving the detection component 300 to move left and right along the top of the detection platform 100. Since several sets of pressure sensors are embedded in the curved surface of the bottom of the movable detection component 320 from front to back, and several sets of pressure sensors are embedded in the curved surface of the top of the fixed detection component 310 from front to back, the movable detection component 320 and the fixed detection component 310 can be separated during the left-right movement of the detection component 300. Do not inspect the flatness of the upper and lower surfaces of the double-sided conductive fabric. After the inspection is completed, start the drive motor and rotate the take-up roller 120 to wind up the inspected double-sided conductive fabric inside the take-up groove 121. Release the uninspected double-sided conductive fabric from the outside of the unwinding groove 111 and tension it above the inspection table 100. Repeat the above steps to continuously inspect the flatness of the double-sided conductive fabric. Therefore, the final effect is to greatly improve the inspection efficiency, thereby meeting the requirements of large-scale inspection. At the same time, compared with manual inspection, the accuracy of inspection is significantly improved.

[0043] Example 2: Please refer to Figure 1 and Figure 2 During the flatness inspection process, since rolls of double-sided conductive fabric can be placed on the outer sides of both sets of unwinding slots 111, and the winding roller 120 is driven by a drive motor, the rolls of double-sided conductive fabric sleeved on the outer sides of the two sets of winding slots 121 can be wound up simultaneously. While continuously unwinding and winding, the inspection component 300 can continuously inspect the flatness of the upper and lower surfaces of the double-sided conductive fabric. Therefore, the unwinding, winding and inspection processes are linked, which significantly improves the inspection efficiency and can meet the requirements of large-scale inspection.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
