Description

Technical Field

[0001] The invention belongs to the technical field of wig production, and in particular relates to a wig hair bundle amplitude detection device. Background Art

[0002] After the wig bundle is made, the quality inspection department needs to measure the circumference of multiple cross-sections of the bundle. If the bundle is short, only the upper and lower ends of the bundle are measured. If the bundle is long, the middle of the bundle is added as the third measurement point. According to the measurement results, the circumference of the lower end of the bundle is divided by the circumference of the upper end to get the bundle amplitude rate. The test value of the bundle amplitude rate is compared with the amplitude rate standard. The test value is qualified within ±10% of the amplitude rate standard. If the test value is not within this range, the bundle will be returned to the workshop for trimming until it is qualified.

[0003] At present, the detection of hair bundle amplitude rate is carried out manually, using a rope with a scale to wrap around the hair bundle (one end of the hair bundle is pre-tied with an elastic rubber band) for detection. This usually requires two people to work together to complete, and the force applied to the hair bundle at different measuring points needs to be kept basically consistent. There is a certain error in reading the scale when testing with a rope, and it is necessary to ensure that the force at different measuring points is consistent. The force requirements applied to different measuring points are based on feeling, which is difficult to achieve consistency. This leads to large errors. The same person will mostly get different results after multiple tests on the same hair bundle, and different people will also get different test results.

[0012] By adopting the above technical solution, compared with the prior art, the present invention has the following beneficial effects: (1) The working principle of the constant clamping force used in the present invention to detect the circumference of a hair bundle is as follows: a shrinking circular clamping component that forms a regular octagonal detection hole is used to measure the circumference of a certain point of the hair bundle, and the constant clamping force is converted into the torque of the test motor in conjunction with the electrical system. Finally, the pulse equivalent of the test motor at constant torque is converted into the side length of the regular octagon and the radius of the inscribed circle, that is, converted into the circumference of the hair bundle measurement point. The position control mode uses a multi-point sampling method to obtain the functional relationship between the output pulse equivalent of the test motor and the change in the side length of the regular octagon, and the side length of the regular octagon is obtained from the functional relationship. The servo motor position control mode + torque measurement mode is used to accurately calculate the side length of the regular octagon while ensuring that the torque of the same hair bundle is the same.

[0013] (2) The cylinder of the hair bundle clamping mechanism drives the first V-shaped clamping plate and the second V-shaped clamping plate to move synchronously relative to each other to clamp the upper end of the hair bundle, and then the lifting motor of the lifting mechanism drives the hair bundle to move downward. The hair bundle circumference constant force testing mechanism tests different measurement points of the hair bundle. This monitoring method only requires manual insertion of the upper end of the hair bundle into the diamond clamping opening and the hair bundle is taken out after the test. The labor intensity is low, the testing standards are consistent, the test results are more objective and accurate, and the testing efficiency is greatly improved.

[0014] (3) The hair bundle circumference constant force test mechanism uses a test motor to drive the upper cover plate to rotate through gear transmission. Eight upper drive guide grooves are set on the bottom surface of the upper cover plate to drive the upper rollers respectively. The lower rollers coaxial with the upper rollers move in the eight lower fixed guide grooves provided on the lower cover plate, so that the eight isosceles right-angled triangle clamps are linked to achieve the expansion and reduction of the size of the regular octagonal detection hole. The direction of movement of the clamp block is along the length direction of the lower fixed guide groove. The upper drive guide groove drives the clamp block to move during the rotation process. The sliding structure between two adjacent clamp blocks is cleverly designed, in which the anti-winding slider and the long groove are tightly slidably matched to ensure that the hair in the hair bundle will not enter the long groove. The two rows of balls on both sides of the concave slider of the right-angled side of the clamp block slide with the slender slide grooves on both sides of the linear guide rail of the adjacent clamp block bevel to ensure the tightness requirement between the clamp blocks, while reducing the sliding friction and improving the measurement accuracy.

[0015] (4) The lifting mechanism uses a lifting motor to drive the gear along the vertically arranged rack as the power to move up and down. Two left sliders and two right sliders are respectively arranged on the left and right sides of the lifting plate. The two left sliders and the two right sliders slide along the left vertical guide rail and the right vertical guide rail respectively, which can ensure the stability of the lifting plate.

[0016] (5) The hair bundle clamping mechanism uses a cylinder to drive the active rack, which drives the transmission mechanism of the rack through the transmission gear, so that the first V-shaped clamping plate and the second V-shaped clamping plate can move relative to each other synchronously and move in both directions, making the action of clamping and releasing the hair bundle faster and more sensitive. The dovetail groove slider and the dovetail guide rail are slidably matched, so that the dovetail groove slider will not separate from the dovetail guide rail in the height direction, so that the first V-shaped clamping plate and the second V-shaped clamping plate connected at the bottom maintain stability.

[0017] In summary, the present invention has a scientific principle, a compact structure, and is more convenient and quick to test the hair bundle width, thereby reducing the labor intensity of workers and improving work efficiency. The clamping force when testing different measuring points of the same hair bundle is consistent, thereby improving the accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific working process of the present invention is as follows: the lifting motor 38 is started, the lifting motor 38 drives the lifting gear 39 to rotate, the lifting gear 39 moves upward along the vertical rack 40, the left slider 36 and the right slider 37 slide upward along the left vertical guide rail 34 and the right vertical guide rail 35 respectively, driving the lifting plate 33 and the entire hair bundle clamping mechanism to move upward along the left column 4 and the right column 5, and after rising to the set highest position, the lifting motor 38 is turned off, the tester takes the wig hair bundle and extends the upper end of the hair bundle into the diamond clamping port 55, the cylinder 43 is started, the piston rod of the cylinder 43 retracts, and the piston rod drives the first dovetail groove slide through the linkage plate 56 The block 46 moves to the left along the first dovetail guide rail 44, and then the first connecting plate 51 and the first V-shaped clamping plate 52 also move to the left. At the same time, the active rack 48 connected to the first dovetail groove slider 46 drives the transmission gear 49 to rotate, and the transmission gear 49 removes the driven rack 50 to move to the right, and the driven rack 50 drives the second dovetail groove slider 47 to move to the right along the second dovetail guide rail 45, and then the second connecting plate 53 and the second V-shaped clamping plate 54 also move to the left. As the first V-shaped clamping plate 52 moves to the left and the second V-shaped clamping plate 54 moves to the right, the diamond clamping opening 55 gradually shrinks to clamp the upper end of the hair bundle.

[0029] Then, the lifting motor 38 is started, and the lifting motor 38 drives the lifting gear 39 to move downward along the vertical rack 40. The hair bundle clamping mechanism drives the hair bundle to move downward, and the hair bundle enters the large bearing 16 of the top cover plate 13 of the hair bundle circumference constant force testing mechanism 7. The lifting motor 38 is paused, and the test motor 8 is started. The test motor 8 drives the test main gear 9 to rotate, and the test main gear 9 drives the meshing sector gear 10 to rotate, and the top cover plate 13 fixedly connected to the sector gear 10 rotates, and the top cover plate 13 is driven simultaneously through the eight upper drive guide grooves 32 opened on the bottom surface. The eight upper rollers 20 move, and the lower roller 21 coaxial with the upper roller 20 moves along the lower fixed guide groove 31 provided on the bottom cover plate 12. The eight clamping blocks 18 move toward the center of the cylindrical shell 11 at the same time. The anti-winding slider 29 slides in the long groove 22. The two rows of balls 26 on both sides of the groove 25 of the concave slider 24 roll along the linear guide 28 and the slender slide grooves 27 on both sides of the linear guide 28. The side length of the regular octagonal detection hole 30 is shortened until the lower part of the hair bundle is clamped. The clamping force of the clamping block 18 on the hair bundle is determined by the torque of the test motor 8. Torque (T) = Torque constant (Kt) × current (I) / motor efficiency, wherein the torque constant (Kt) represents the torque generated by the test current (I) per ampere (A), the current (I) is the current value of the test motor 8, and the motor efficiency takes into account the energy conversion efficiency of the motor. The data processing device 3 reads the current in the test motor 8 (servo motor) in real time through the analog port and converts it into a torque value. When the set torque value is reached, it is considered that the force of the clamping detection of the hair bundle meets the requirements.

[0030] When the clamping force reaches the requirement, the perimeter of the regular octagonal detection hole 30 (the perimeter of the hair bundle) is determined by the following calculation method: First, each time the machine is turned on for detection, the data processing device 3 automatically controls the test motor 8 to rotate until the regular octagonal detection hole 30 is closed. When the regular octagonal detection hole 30 is closed, the eight clamps 18 squeeze each other, and the torque of the test motor 8 increases exponentially. When the set torque is reached, the test motor 8 is stopped, and the position of the test motor 8 at this time is set as the zero point (origin).

[0031] When measuring, the test motor 8 drives the eight clamps 18 to move. When the regular octagonal detection hole 30 formed by the eight clamps 18 clamps the hair bundle to reach the set torque, the position of the test motor 8 at this time is read (as a pulse equivalent), and the rotation angle of the test motor 8 can be obtained according to the origin. Then, according to the relationship between the angle of the test motor 8 and the regular octagonal detection hole 30, the side length of the regular octagonal detection hole 30 can be obtained. The formula is as follows: y=0.01X+2 (0≤pulse amount<100) y=0.02X+1 (100≤pulse amount<300) y=0.03X-2 (300≤Pulse amount<500) y=0.035X-5 (500≤Pulse amount<700) y=0.045X-12 (700≤Pulse amount<900) y=0.055X-21 (900≤Pulse amount<1000) Wherein y represents the side length of the regular octagon, and X represents the pulse quantity of the test motor 8 read by the PLC controller, from which the side length of the regular octagonal detection hole 30 can be obtained. Furthermore, the relationship between the side length y of the regular octagonal detection hole 30 and the inscribed circle of the regular octagonal detection hole 30 is: r=y / 2cos67.5°; r represents the radius of the inscribed circle.

[0032] According to the above calculation principle, the data processing device 3 can obtain the circumferential length of the hair bundle according to the torque of the test motor 8, and then obtain the cross-sectional area of ​​the hair bundle.

[0033] After testing the cross-sectional area of ​​an interface at the lower part of the hair bundle, the test motor 8 is started to rotate in the reverse direction, and the eight clamping blocks 18 release the hair bundle.
