[0034] like Figure 1 As shown, an embodiment of the present application provides a coil inspection device 100, primarily used for sampling coils for appearance quality inspection. Coil inspection device 100 includes a mobile platform 110 and an unwinding assembly 120, a rewinding assembly, and a detection assembly 140 disposed on mobile platform 110. This allows for on-site inspection using mobile platform 110, enhancing the flexibility of coil inspection.

[0035] The unwinding assembly 120 is used to unwind the coiled material.

[0036] In some embodiments, the unwinding assembly 120 includes a first fixing frame 121 and a first fixing shaft 1223 .

[0037] like Figure 1 As shown, the first fixing bracket 121 is fixed on the mounting platform 111 .

[0038] The first fixed shaft 122 is detachably connected to the fixed frame to facilitate material replacement and loading.

[0039] The reeling assembly 130 and the unreeling assembly 120 are spaced apart along the first direction D1. The reeling assembly pulls the unreeled coil to flatten the unreeled coil, so that the detection assembly 140 can quickly detect defects in the coil.

[0040] In some embodiments, the winding assembly 130 includes a second fixing frame 131 and a second fixing shaft 132 .

[0041] Specifically, the second fixing shaft 132 is detachably connected to the second fixing frame 131 , and the first fixing shaft 122 and the second fixing shaft 132 are parallel and spaced apart along the first direction D1 .

[0042] Thus, after the sampling is completed, the second fixed shaft 132 is disassembled from the second fixed frame 131, and the coil on the second fixed shaft 132 is removed so that the next coil can be inspected or sampled.

[0043] In this embodiment, the end of the coil released from the first fixed shaft 122 is pulled out and fixed on the second fixed shaft 132, and the driving member 133 drives the second fixed shaft 132 to rotate along its axial direction, thereby continuously pulling out and flattening the coil released by the unwinding assembly 120, and the coil is wound on the second fixed shaft 132.

[0044] In other embodiments, the rewind assembly 130 can be configured as a set of rollers arranged in parallel vertically. The end of the coiled material unwound from a fixed shaft passes through the gap between the rollers. The rollers rotate, and the coiled material unwound from the unwind assembly 120 is continuously pulled out and flattened, and the coiled material flows into the waste collection frame. The inspection assembly 140 is disposed between the unwind assembly 120 and the rewind assembly 130 and is used to inspect the flattened coiled material. In this way, the coiled material is continuously pulled out by the rewind assembly 130, and the inspection assembly 140 simultaneously inspects the pulled-out coiled material, thereby improving inspection efficiency.

[0045] like Figure 1 As shown, in some embodiments, the mobile platform 110 includes a mounting platform 111 , a support column 112 , a base plate 113 and a plurality of rollers 114 .

[0046] The unwinding assembly 120 , the rewinding assembly and the detecting assembly 140 are all arranged on a table top of the mounting table 111 , and the table top is roughly rectangular.

[0047] The bottom plate 113 is rectangular, and a storage box 115 is provided above the bottom plate 113 for storing cut samples, utility knives, labels, air shafts, waste collection frames, small air pumps, and simple maintenance tools.

[0048] The rollers 114 are brakeable rollers 114 , and four rollers 114 are disposed at four corners below the bottom plate 113 .

[0049] In some embodiments, the mobile platform 110 further includes a push rod or a hook to facilitate manual pushing or dragging of the coil inspection device 100 to various workshops by a trailer, thereby improving the flexibility of coil inspection.

[0050] In some embodiments, the unwinding assembly 120 further includes a switch member 123 .

[0051] The switch 123 is connected to the first fixing frame 121 . When the switch 123 is turned on, the first fixing shaft 122 is separable from the first fixing frame 121 . When the switch 123 is turned off, the first fixing shaft 122 is fixedly connected to the first fixing frame 121 .

[0052] Specifically, when the switch 123 is turned on, the material is replaced or loaded; when the switch 123 is turned off, the coil is inspected and sampled.

[0053] In some embodiments, the first fixed shaft 122 is an inflatable shaft.

[0054] An air shaft, also known as an air reel or air shaft assembly, is a device that automatically adjusts the winding diameter to accommodate varying material sizes. The air shaft relies on air pressure, inflating and deflating the shaft to change its diameter, thereby adjusting the tightness or looseness of the reel to ensure smooth winding without twisting or damage.

[0055] The inflatable shaft includes a shaft body, which is usually made of metal or plastic and has sufficient strength and durability.

[0056] In some embodiments, the first fixing frame 121 includes a first fixing wall 1211 and a second fixing wall 1212 that are oppositely disposed.

[0057] The first fixing wall 1211 is provided with a first groove 12111, the first groove 12111 has an opening facing away from the first fixing wall 1211, and the first groove 12111 is U-shaped. Figure 1 As shown, the groove of the first groove 12111 faces the right side. In other embodiments, the opening of the first groove 12111 can also be set upward.

[0058] In this embodiment, a second groove (not shown) is provided on the second fixed wall 1212, and the second groove has an opening facing away from the second fixed wall. The first groove 12111 and the second groove are spaced apart along the second direction D2, and one end of the first fixed axis 122 is connected to the first groove 12111, and the other end is connected to the second groove.

[0059] It should be noted that the second direction D2 is the width direction of the coil, and the first direction D1 is perpendicular to the width direction of the coil, that is, the forward direction of the coil. Figure 1 In the first direction D1, the left-right direction is Figure 2 In the embodiment, the first direction D1 is a left-right direction and is parallel to the length direction of the mounting platform 111 , and the second direction D2 is a top-bottom direction and is parallel to the width direction of the mounting platform 111 . The first direction D1 and the second direction D2 are perpendicular to each other.

[0060] In other embodiments, a through hole is defined on the second fixing wall 1212 , one end of the first fixing shaft 122 is inserted into the through hole, and the other end slides into the first groove 12111 , thereby achieving a detachable connection between the first fixing shaft 122 and the first fixing frame 121 .

[0061] In some embodiments, there are two switch members 123, one switch member 123 is arranged at the opening of the first groove 12111, and the other switch member 123 is arranged at the opening of the second groove. The switch member 123 is used to close or open the opening of the first groove 12111 or the second groove.

[0062] For example, Figure 1 As shown, the switch member 123 is a plug-in type bolt switch.

[0063] A plug-in bolt switch typically contains a bolt or slider (called a "moving contact") that triggers the switch to turn on or off when the bolt is inserted or removed.

[0064] When the bolt is inserted, the end of the first fixed shaft 122 is fixed between the bottom of the first groove 12111 and the bolt. When the bolt is pulled out, the end of the first fixed shaft 122 can be moved out from the opening of the first groove 12111. The operation is simple and convenient for quick loading.

[0065] In some embodiments, the winding assembly 130 further includes a driving member 133 .

[0066] In some embodiments, the driving member 133 is a handwheel connected to the end of the second fixed shaft 132, so that the winding speed of the second fixed shaft 132 can be controlled, which is convenient for manual inspection and makes sampling operations more convenient. The handwheel has low cost.

[0067] In some embodiments, the winding assembly 130 further includes a meter counter 134 , which is connected to the second fixing frame 131 .

[0068] As will be understood, meter counter 134 is a device for measuring linear distance, primarily used to record the length of an object or path in meters. The probe of meter counter 134 contacts second fixed shaft 132. When the handwheel rotates second fixed shaft 132, friction drives the input shaft of an encoder (control panel) within meter counter 134. The encoder (control panel) counts the number of revolutions of roller 114 and converts this into meters of web travel.

[0069] In some embodiments, the detection assembly 140 includes a searchlight 141 , which is detachably connected to the mobile platform 110 .

[0070] like Figure 2 As shown, the searchlight 141 adopts an LED lamp. When the LED lamp is fixed on the mounting platform 111, the LED lamp is below the flattened coil and irradiates the coil upwards.

[0071] The LED light is a strip light, which is conducive to expanding the illumination range. The light intensity and color temperature of the LED light are adjustable, which is convenient for detecting different types of coils.

[0072] The searchlight 141 has a magnetic lamp holder 142, so that the position of the searchlight 141 can be adjusted as needed. In addition, the searchlight 141 can be lifted from the mounting platform 111 to change the illumination angle of the searchlight 141, so that the defects of the coil can be illuminated at close range, which is convenient to operate.

[0073] It can be understood that when the unwinding component 120, the detection component 140 and the rewinding component 130 are used together to sample the coil, the coil that has been detected is a waste coil. After the sampling is completed, the coil on the rewinding component can be discarded.

[0074] When the unwinding assembly 120, the detection assembly 140 and the rewinding assembly 130 cooperate, the coil needs to be flattened for easy visual inspection. Based on the above requirements, the coil inspection device 100 also includes a correction assembly 150 for aligning the edges of the coil rewound by the rewinding assembly 130.

[0075] like Figure 1 and Figure 2 As shown, the deviation-correcting assembly 150 is disposed on the mounting platform 111 and is located between the detecting assembly 140 and the unwinding assembly 120 .

[0076] The correction component 150 includes a first roller group 151 and a second roller group 152. The first roller group 151 and the second roller group 152 are arranged at intervals along the second direction D2. The first roller group 151 and the second roller group 152 are respectively movably connected to the movable platform 110 to adjust the distance between the first roller group 151 and the second roller group 152 to facilitate the correction of rolls of different widths.

[0077] Exemplarily, the first roller group 151 and the second roller group 152 have the same structure. The first roller group 151 has two roller shafts arranged one above the other, and the distance between the two roller shafts is adjustable to facilitate clamping of coils of different thicknesses.

[0078] The first roller group 151 and the second roller group 152 clamp the two side edges of the coil along the width direction of the coil to reduce the swing of the coil during movement and align the edges of the coil after being wound by the second fixed shaft 132.

[0079] In this embodiment, the correction assembly 150 also includes a guide rail 153, which is fixed to the movable platform 110 and extends along the second direction D2. The first roller group 151 and the second roller group 152 are respectively slidably arranged on the guide rail 153, and the guide rail 153 is provided with a scale arranged along the second direction D2.

[0080] In some embodiments, the table top of the mounting table 111 is rectangular, the central axis direction of the flattened roll is aligned with the axis direction of the mounting table 111, the brightness of the scale is marked as zero scale, and the scale value becomes larger towards the middle of the mounting table 111, so as to facilitate the correction of the flattened roll and align the edges of the roll after the second fixed shaft 132 is wound up.

[0081] The working process of the coil inspection device 100 is as follows:

[0082] Pull up the plug-in bolt switch of the unwinding assembly 120 to move the end of the inflatable shaft out of the opening of the first groove 12111 or the second groove;

[0083] Place the slit material roll to be inspected on the first fixed shaft 122 (center it as much as possible), and adjust the positions of the first roller group 151 and the second roller group 152 so that the distance between the two roller groups is adapted to the width of the material roll;

[0084] The end of the manually coiled material is wound around the second fixed shaft 132;

[0085] The air shaft is inflated to fix the material roll on the first air shaft;

[0086] Light up the LED light and adjust the color temperature and brightness;

[0087] Turn on the meter counter 134 and start winding. After the defect or flaw is pulled out, record the corresponding number of meters. Adjust the light color temperature and brightness to observe the shape and area of the defect. Use a utility knife to cut once in front of the unwinding component 120 and in front of the winding component 130 to remove the defective sample completely for inspection.

[0088] Then, the remaining coils in the unwinding assembly 120 and the rewinding assembly 130 are unloaded.

[0089] The coil inspection device 100 of the present application can be freely moved to various places in the factory, thereby improving the flexibility of coil inspection. It is also small in size and simple in structure, making it easy to transport and operate.

[0090] Furthermore, when inspection equipment during the production process displays the defect type and location, workers physically sample the diaphragm roll. This is crucial for classifying diaphragm defects, confirming their physical properties, and enabling subsequent improvements. It also serves as a reverse verification of the inspection equipment's accuracy, preventing missed defects and misclassification, effectively curbing the flow of defective diaphragms during production.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0092] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
