Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image sensors, in particular to a textile surface roughness detection device based on an image sensor. BACKGROUND

[0002] Textile roughness detection refers to a process link of quantifying the unevenness of the fabric surface through instrument measurement. The core purpose is to control the appearance quality, tactile comfort and functional performance of the product. The standard method uses optical sensors such as lasers to vertically scan the surface of a fixed sample, generate a three-dimensional topography map and calculate parameters, thereby achieving accurate and repeatable quality control.

[0003] According to the search, the patent with the publication number CN117968586B includes a detection angle switching mechanism, a detection support mechanism, a visual acquisition module, and a tension control assembly. The rear end of the tension control assembly is installed with a vertical plate, the bottom of the vertical plate is installed with a bottom plate, the surface of the bottom plate is provided with an output guide roller, and one side of the output guide roller is installed with a clamping drive guide roller. One end of the clamping drive guide roller is installed with a motor. The detection device controls the rotation of the detection support mechanism through the detection angle switching mechanism, which can change the included angle between the visual acquisition module and the detected clothing surface during detection, expand the detection picture angle control range, and cooperate with the tension control assembly at the bottom to ensure that the tension of the detected fabric is fixed at any time, avoiding the interference of the difference in the stretched state of the elastic fabric caused by the change of the tension on the final detection result.

[0004] However, the premise of roughness detection is that the fabric surface is in a flat and stable state. Compared with the conventional flat laying method, the above-mentioned scheme is vertically stretched when shooting, at which time too small tension will cause the fabric to wrinkle due to vertical falling, and too large tension will cause the structure of the fabric surface to be flattened, covering the original concave-convex, wrinkles and texture, resulting in the measured roughness value being lower than the actual value, causing data distortion. The roughness detection result of the fabric in the vertical state is greatly affected by the tension, so precise tension control is required. However, the precision of the tension control assembly in the above-mentioned scheme is obviously low, and it is difficult to meet the control requirements of balancing the tension of the fabric surface. That is, there is a large error in the authenticity of the roughness data measured by the above-mentioned scheme. SUMMARY

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 9 The present application provides a technical solution: a textile surface roughness detection device based on an image sensor, which comprises a base 1, further comprises a flattening assembly for controlling the flatness of the textile and a timing mechanism for controlling the movement sequence of the flattening assembly, negative pressure holes 11 are formed around the base 1, and an annular shallow groove 12 is formed at the center of the upper surface of the base 1.

[0033] The timing mechanism comprises a fixed plate 2 in a fixed state, which is arranged directly above the base 1.

[0034] The flattening assembly comprises a driving mechanism for synchronous operation with the timing mechanism, a carding mechanism for eliminating wrinkles on the surface of the textile, and a pressure mechanism for fixing the textile; the driving mechanism comprises a positioning shaft 3 fixedly connected with the timing mechanism, the pressure mechanism comprises a positioning disc 4 fixedly connected with the timing mechanism, and the carding mechanism comprises a sliding block 5 fixedly connected with the driving mechanism and the pressure mechanism.

[0035] In this scheme, the textile to be detected is placed on the upper surface of the base 1 and kept in the middle, and then a negative pressure suction mechanism is installed at the bottom end of the base 1. Since the negative pressure suction mechanism is prior art, it will not be described here. Further, under the action of the negative pressure suction mechanism, the textile is adsorbed through the negative pressure hole 11 to achieve pre-fixing, avoiding movement of the textile during subsequent combing and smoothing, which can cause combing failure.

[0036] Subsequently, the timing mechanism controls the operation of the flattening assembly, and the combing mechanism starts to work synchronously to smooth and comb the surface of the textile in the pre-fixed state. By combing from the center of the textile surface to the four edges, the wrinkles on the surface of the textile are pushed to the edges and discharged, thereby removing the macro wrinkles on the surface of the textile.

[0037] When the combing mechanism is fully extended, the combing operation is completed, the negative pressure suction mechanism is turned off, the negative pressure hole 11 releases the pre-fixing of the textile, and the textile returns to a free state. Subsequently, the pressure mechanism works synchronously with the annular shallow groove 12 to achieve the downward fixation of the textile. The edge of the textile is pressed with constant light pressure, and the wrinkles are eliminated by natural downward pressure, which only applies very small and uniform vertical pressure, almost without plane direction tension, thereby effectively avoiding the stretching distortion of the surface of the textile, and achieving the final tension-free fixation effect of the textile.

[0038] Embodiment 2

[0039] Please refer to Figure 4 , this embodiment is further described based on embodiment one: the center of the fixed plate 2 is penetrated and connected with a positioning rod 21 through damping sliding, the two sides of the positioning rod 21 are fixedly connected with a rack one 22, the rack one 22 is also penetrated and connected with the fixed plate 2 through damping sliding, the two sides of the rack one 22 away from the positioning rod 21 are provided with a rack two 23, the rack two 23 is also penetrated and connected with the fixed plate 2 through damping sliding, the two sides of the rack two 23 away from the rack one 22 are provided with a rack three 24, the rack three 24 is also penetrated and connected with the fixed plate 2 through damping sliding.

[0040] The lower surface of the fixed plate 2 is fixedly connected with a fixed pin 25, and the same double screw rod 26 is penetrated and rotationally connected through limiting on the two sides of the fixed pin 25, the middle segment of the double screw rod 26 is fixedly connected with a motor 27, and the transmission gear 28 is penetrated and connected through damping screw on the outer contour of the double screw rod 26 on both sides of the motor 27.

[0041] The threads on the outer contour of the double screw rod 26 on both sides of the motor 27 are opposite in direction, and the two transmission gears 28 are initially connected with the rack one 22 in the corresponding position through meshing transmission.

[0042] As can be seen from Embodiment 1, the timing mechanism serves as the power source for the entire device. When the textile is placed on the upper surface of the base 1 and pre-fixed by the negative pressure hole 11, the motor 27 is started and drives the bidirectional lead screw 26 to rotate. At this time, the transmission gear 28 tends to rotate synchronously. However, in the initial state, the transmission gear 28 is also meshed with the rack 22 for transmission. The rack 22 and the fixed plate 2 are connected by a damping sliding connection. That is, if the transmission gear 28 wants to rotate with the bidirectional lead screw 26, it needs to overcome the sliding resistance between the rack 22 and the fixed plate 2 to achieve synchronous lifting and lowering of the rack 22.

[0043] The double-acting lead screw 26 and the transmission gear 28 achieve synchronous rotation through static friction. When the rotational resistance applied by the rack 22 to the transmission gear 28 is greater than the static friction between the transmission gear 28 and the double-acting lead screw 26, relative motion will occur between the transmission gear 28 and the double-acting lead screw 26, which will cause the transmission gear 28 to travel along the axial direction of the double-acting lead screw 26 under the action of its screw connection with the double-acting lead screw 26.

[0044] In summary, the frictional resistance between rack 1 22 and fixed plate 2, rack 2 23 and fixed plate 2, and rack 3 24 and fixed plate 2 in the initial state are all set to be less than the static friction between transmission gear 28 and double-acting lead screw 26. At this time, if... Figure 4 As shown, when the motor 27 drives the bidirectional lead screw 26 to rotate clockwise, the transmission gear 28 rotates clockwise synchronously and drives the rack 22 and the positioning rod 21 to descend synchronously. The positioning rod 21 further drives the entire drive mechanism to descend. However, the descent stroke of the drive mechanism has a limit. When it descends to the limit position, the positioning rod 21 and the rack 22 can no longer descend. That is, at this time, the rotational resistance provided by the rack 22 to the transmission gear 28 is infinite. The bidirectional lead screw 26 continues to rotate, which causes the transmission gear 28 to move from the middle section of the bidirectional lead screw 26 to both ends. This causes the transmission gear 28 to disengage from the rack 22 and begin to mesh with the rack 23. The subsequent process is the same as the above process. After the rack 23 descends synchronously to the limit stroke, the transmission gear 28 moves again along the bidirectional lead screw 26 to both ends, causing the transmission gear 28 to mesh with the rack 3 24. The rack 3 24 drives the pressure mechanism to descend synchronously, thereby achieving the purpose of controlling the operating sequence of each mechanism of the flattening assembly.

[0045] It should be noted that, since the threads on both sides of the bidirectional screw rod 26 are opposite in direction, the two transmission gears 28 always move in opposite directions along the bidirectional screw rod 26, that is, when the bidirectional screw rod 26 rotates clockwise, the two transmission gears 28 move away from each other, and when the bidirectional screw rod 26 rotates counterclockwise, the two transmission gears 28 move towards each other, so that the engagement state of the two transmission gears 28 with the corresponding positions of the rack one 22, the rack two 23 and the rack three 24 is always synchronized, thereby ensuring that the lifting process of the flattening assembly always maintains a horizontal state.

[0046] Similarly, after the roughness detection is completed, the flattening assembly needs to be reset, at which time the motor 27 is started to drive the bidirectional screw rod 26 to rotate counterclockwise. Since during the previous descending process, the transmission gears 28 have moved to the two ends of the bidirectional screw rod 26, during the counterclockwise rotation of the bidirectional screw rod 26, the transmission gears 28 first engage with the rack three 24 and drive the rack three 24 to rise, and when the rack three 24 rises to the limit position, the transmission gears 28 begin to move towards the middle of the bidirectional screw rod 26 and engage with the rack two 23, driving the rack two 23 to rise. When the rack two 23 rises to the limit position, the transmission gears 28 again engage with the rack one 22 and drive the rack one 22 and the positioning rod 21 to rise, thereby realizing the sequential resetting of each mechanism of the flattening assembly, and the resetting sequence is opposite to the operating sequence, avoiding motion interference between the mechanisms of the flattening assembly.

[0047] It should be noted that, since the rack one 22 and the fixed plate 2, the rack two 23 and the fixed plate 2, and the rack three 24 and the fixed plate 2 are all connected by damping sliding, by setting the frictional resistance of their connection to be greater than their own gravity, the timing mechanism as a whole will not accidentally fall without external force.

[0048] Embodiment 3

[0049] Please refer to Figures 5 to 7 , this embodiment is further explained on the basis of embodiment two: the positioning shaft 3 is fixedly connected to the bottom end of the positioning rod 21, the bottom end of the positioning shaft 3 is fixedly connected with an image sensor 31, the outer contour of the middle section of the positioning shaft 3 is fixedly connected with a cross 32 extending downward, the outer contour of the lower half of the positioning shaft 3 is sleeved with a positioning cylinder 33, the center of the positioning cylinder 33 is provided with a detection cavity 34, and a plurality of sliding grooves 35 are formed on the outer contour of the positioning cylinder 33.

[0050] The multiple corners of the bottom end of the cross 32 are slidingly connected in the corresponding position of the sliding groove 35, and the image sensor 31 is located inside the detection cavity 34.

[0051] The positioning disc 4 is fixedly connected to the bottom end of the rack two 23, the bottom end of the positioning disc 4 is fixedly connected with a plurality of downward extending connecting rods 41, a plurality of the connecting rods 41 are also slidingly connected in the corresponding position of the sliding groove 35, and a same outer shell 42 is commonly sleeved on the outer contour of the plurality of connecting rods 41, and the upper surface of the outer shell 42 is fixedly connected with the bottom end of the rack three 24.

[0052] As can be seen from example two, when the positioning rod 21 and the rack one 22 descend, the positioning shaft 3, the image sensor 31 and the cross 32 are synchronously lowered, and at this time, the transmission gear 28 has not contacted with the rack two 23, so the height of the positioning disc 4 remains unchanged, and the cross 32 further drives the bottom end of the carding mechanism to descend synchronously, when the carding mechanism descends and contacts with the textile which is pre-fixed by the negative pressure hole 11 on the upper surface of the base 1, the carding mechanism cannot continue to descend, at this time, the continuous descent of the cross 32 will extrude and drive the carding mechanism to expand laterally, in the process of lateral expansion of the carding mechanism, the bottom end thereof spreads from the center of the textile surface to the periphery, and then the macroscopic wrinkles on the textile surface are pushed to the edge by flattening, and then the wrinkles are discharged through the edge of the textile, so as to realize the pre-flattening effect.

[0053] When the carding mechanism connected with the bottom end of the cross 32 is completely expanded laterally, the cross 32 cannot continue to descend, at this time, the transmission gear 28 is disengaged from the rack one 22 and engaged with the rack two 23 due to the increased rotating resistance of the rack one 22 to the transmission gear 28, and then the rack two 23 drives the positioning disc 4 and the connecting rod 41 to descend, and the carding mechanism at the bottom end of the connecting rod 41 descends synchronously, and the same as the above process, the carding mechanism completes the flattening operation on the textile surface again, so as to cooperate with the carding mechanism in the previous motion stroke to realize the effect of eliminating the wrinkles on the whole textile surface.

[0054] When the carding mechanism is expanded, the rack two 23 also cannot continue to descend, so that the transmission gear 28 is disengaged from the rack two 23 and engaged with the rack three 24, and then the rack three 24 drives the outer shell 42 to descend, and the bottom end of the outer shell 42 gradually descends and contacts with the carding mechanism, so that the carding mechanism is inserted into the annular shallow groove 12 to realize the pressure fixation of the textile; after the textile is fixed, the roughness of the textile surface in the detection cavity 34 is detected by the image sensor 31, at this time, the image sensor 31 and the textile surface are in a vertical angle, the shooting effect is best, and after the textile is pre-flattened, the edge of the textile is vertically pressed into the annular shallow groove 12 in the pressure fixation link, so as to eliminate the macroscopic wrinkles in the central area of the textile while hardly producing any horizontal tensile force, so as to keep the test area natural and flat, and greatly reduce the error in roughness detection.

[0055] Example 4

[0056] Please refer to Figure 8 and Figure 9 The embodiment is further illustrated on the basis of Embodiment Three: the sliding blocks 5 are provided in plurality and correspond to the number of the grooves 35, each sliding block 5 is slidingly connected in the groove 35 at the corresponding position and fixedly connected with the bottom end of the connecting rod 41 or the cross 32, each sliding block 5 is rotatably connected with the connecting rod 51 through the pin shaft, one end of each connecting rod 51 away from the sliding block 5 is rotatably connected with the positioning block 52 through the pin shaft, one end of each positioning block 52 away from the connecting rod 51 is fixedly connected with the silica gel head 53, the inside of each silica gel head 53 is slidingly connected with the plug plate 54 vertically, and each plug plate 54 is fixedly connected with the compression spring 55 between the top end and the silica gel head 53 at the corresponding position.

[0057] As can be seen from Embodiment Three, when the cross 32 or the connecting rod 41 descends, the combing mechanism connected therewith descends synchronously, that is, the sliding block 5 drives the connecting rod 51, the silica gel head 53 and the silica gel head 53 to descend synchronously; when the silica gel head 53 descends to the bottom end thereof and contacts the surface of the textile, the silica gel head 53 cannot continue to descend, and the sliding block 5 continues to descend with the cross 32 or the connecting rod 41, under the descending action of the sliding block 5, the connecting rod 51 starts to deflect and pushes out the positioning block 52 and the silica gel head 53 outward, at this time, the movement track of the silica gel head 53 is horizontally outward, so as to push the wrinkles on the surface of the textile to move towards the edge and be discharged, realizing the combing effect on the surface of the textile.

[0058] It should be noted that, since the cross 32 starts to descend first, the plurality of silica gel heads 53 at the bottom end thereof start to expand and complete the combing action, then the connecting rod 41 starts to descend and drives the remaining silica gel heads 53 to expand, the expansion tracks of this part of silica gel heads 53 and the previous silica gel heads 53 are staggered, so as to realize the overall combing of the surface of the textile and further eliminate the macro wrinkles on the surface of the textile.

[0059] Further, the plurality of silica gel heads 53 in the fully expanded state jointly splice into a circular ring structure, at this time, the rack three 24 drives the shell 42 to descend, the bottom end of the shell 42 gradually descends and contacts the plug plate 54 in the plurality of silica gel heads 53, under the descending extrusion of the shell 42, the bottom end of the plug plate 54 stretches out from the inside of the silica gel head 53 and drives the compression spring 55 to be compressed, since the bottom end of the plug plate 54 corresponds to the position of the annular shallow groove 12 at this time, the stretching out of the plug plate 54 will extrude the textile and cause the edge of the textile to be vertically inserted into the annular shallow groove 12, further realizing the fixing effect of the textile and almost not producing the tensile force in the horizontal direction, realizing the tensionless flattening effect of the central area of the textile.

[0060] It should be noted that the depth of the plug plate 54 inserted into the annular shallow groove 12 can be adjusted by controlling the descending height of the shell 42, thereby realizing the adjustment of the pressure when the textile is fixed by being pressed down, so as to meet the adjustment of the tension of different elastic textiles, and the suitable fixing pressure is selected according to the material of the textile, and the applicability of the scheme is further expanded,

[0061] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
