Technical Field

[0001] The invention belongs to the technical field of orthosis production, and relates to a finished product processing process of an orthosis sensing orthosis area pressure sensor. Background Art

[0002] Orthotics are a general term for external devices that are fitted to the limbs, trunk and other parts of the human body. Their purpose is to prevent or correct deformities of the limbs and trunk or to treat bone and joint and neuromuscular diseases and compensate for their functions.

[0003] With the progress of the times, orthoses have gradually been upgraded from ordinary purely mechanical structures to electronic ones. Many orthoses are equipped with electronic devices such as pressure sensors and temperature sensors to monitor the position of joints at all times. Because there are many electronic components inside orthoses, insulation treatment between various components is necessary. In particular, pressure sensors are the most indispensable sensors in orthoses, and insulation treatment during their production process is of great significance.

[0004] At present, the finished pressure sensors for orthotics are directly packaged and put on the market after passing through the routine testing environment, and there is no special insulation treatment for the pressure sensors. Therefore, it is necessary to carry out insulation treatment before the pressure sensors are put on the market. Summary of the invention

[0005] The purpose of the present invention is to address the problem that existing special pressure sensors for orthotics are directly put on the market without insulation treatment after being finished, and to propose a finished product processing process for orthotic induction orthotic area pressure sensors.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A finished product processing process of an orthotic sensing orthotic area pressure sensor comprises the following steps: S1, take the finished packaged sensors, and place them uniformly after they meet the specifications through bridge circuit detection, pressure detection, and resistance test; S2, after wrapping the sensors with insulating tape in a production line, they are uniformly placed; S3, after wrapping the sensors with insulating tape vertically in an assembly line manner, they are uniformly placed; S4, conduct insulation test on the insulation degree of the sensor surface. The insulation test process is carried out using an insulation resistance tester. Qualified products are placed together, and unqualified products repeat steps S2 and S3; S5, sampling sensors are tested on the machine. The test process is continuous and lasts for more than 48 hours. When all the sampled samples pass the test, all sensor samples are collected and other sensors that have not been tested are placed together; S6, separate and package the untested sensors and package the qualified sensor samples separately.

[0007] In the above-mentioned finished product processing process of the orthosis sensing orthosis area pressure sensor, a winding success detection link is also provided between S3 and S4, and the detection link includes the following steps: selecting the wound sensor, and neatly placing the sensor on the detection platform in the form of rows and columns of horizontal X pieces and vertical Y pieces, and passing through the edge of the sensor by the linear displacement of the upper laser probe on the X-axis and Y-axis to detect whether the edge of the sensor in each row and column has the thickness of the insulating tape.

[0008] In the above-mentioned finished product processing process of the orthosis sensing orthosis area pressure sensor, the values ​​of X and Y are the same.

[0009] In the above-mentioned finished product processing process of the orthosis sensing orthosis area pressure sensor, the X and Y values ​​are 10.

[0010] In the above-mentioned finished product processing process of the orthotic device sensing orthotic area pressure sensor, the insulating tape is wound from the winding wheel onto the sensor, and a winding tape component identification link is provided after S2 and S3. The identification link is implemented by the following method: a photoelectric encoder is provided on the rotating shaft of the winding wheel to record the number of revolutions of the winding wheel after a single sensor is wound with the insulating tape. After obtaining the number of revolutions of the winding wheel, the amount of the insulating tape separated can be obtained to determine whether the winding tape is sufficiently wound onto the sensor.

[0011] In the above-mentioned finished product processing process of the orthosis sensing orthosis area pressure sensor, the S5 sampling method is: in the sensor transportation line, the appearance of the sensor is identified by a visual sensor, all sensors with abnormal appearance are separated and counted as A, and then the total number of sensors with normal appearance passing through is counted as B, all sensors with abnormal appearance are selected, and sensors with normal appearance are randomly selected, and the selection ratio is A:B≤100:1.

[0012] In the above-mentioned finished product processing process of the orthosis sensing orthosis area pressure sensor, the ratio of the abnormal appearance sensor to the normal appearance sensor is A:B=100:1.

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] A finished product processing process of an orthotic sensing orthotic area pressure sensor comprises the following steps: S1, take the finished packaged sensors, and place them uniformly after they meet the specifications through bridge circuit detection, pressure detection, and resistance test; S2, wrapping the sensor with insulating tape in a pipeline manner in the horizontal direction, the insulating tape is wound and divided from the winding wheel onto the sensor, and then the wound tape quantity identification link is performed, and the identification link is realized by the following method: a photoelectric encoder is set on the rotating shaft of the winding wheel to record the number of turns of the winding wheel after a single sensor is wound with the insulating tape, and the amount of the insulating tape divided can be obtained after obtaining the number of turns of the winding wheel, so as to determine whether the wound tape is wound on the sensor in the horizontal direction in a sufficient amount; S3, after the sensor is vertically wrapped with the insulating tape in an assembly line, the insulating tape is wound from the winding wheel onto the sensor, and then the winding tape quantity identification link is performed, and the identification link is realized by the following method: a photoelectric encoder is set on the rotating shaft of the winding wheel to record the number of turns of the winding wheel after a single sensor is wound with the insulating tape, and the amount of the insulating tape separated can be obtained after obtaining the number of turns of the winding wheel, so as to determine whether the winding tape is sufficiently wound onto the sensor in the longitudinal direction; S4, firstly, the sensor is tested for successful winding, which includes the following steps: select the wound sensor, and neatly place the sensors on the testing platform in rows and columns with 10 pieces in the horizontal direction (X-axis direction) and 10 pieces in the vertical direction (Y-axis direction), and pass through the edge of the sensor by the linear displacement of the upper laser probe on the X-axis and Y-axis to detect whether the edge of each row and column of the sensor has the thickness of the insulating tape, and then perform insulation testing on the insulation degree of the sensor surface. The insulation testing process is carried out using an insulation resistance tester, and qualified products are placed uniformly, and unqualified products repeat steps S2 and S3; S5, sampling sensors and then conducting machine tests. The sampling method is: in the sensor transportation line, the appearance of the sensor is identified by the visual sensor, all sensors with abnormal appearance are separated and counted as A, and then the total number of sensors with normal appearance passing through is counted as B, all sensors with abnormal appearance are selected, and sensors with normal appearance are randomly selected, and the selection ratio is A: B = 100: 1. The test process is continuous and greater than 48 hours. When all sampled samples pass the test, all sensor samples are collected, and other sensors that have not been tested are placed together; S6, separate and package the untested sensors, and separately package the qualified sensor samples. The packaging process uses a honeycomb storage grid packaging box to separate and package the sensors.

[0018] Finally, the obtained sensor passed all performance tests, and its outer circumference was completely covered with a circle of insulating tape, which showed good insulation properties.

[0019] The assembly-line vertical wrapping of the insulating tape by S2 and S3 is achieved by the following winding machine.

[0020] The winding machine includes a casing with a cavity inside and a working platform 1 on the top, and a material changing component 2, a material taking component (not shown in the figure), and a cutting component 3 arranged on the working platform 1; the material changing component 2 is provided with a loading and unloading station and a winding station, and the sensor is shifted and switched between the loading and unloading station and the winding station through the material changing component 2.

[0021] The winding process of each sensor after S2 or S3 is as follows: the material picking component shifts the sensor to be processed to the work platform 1 at the loading and unloading station, and then the material changing component 2 winds the insulating tape on the sensor, and then the cutting component 3 cuts off the sensor that is bent with at least one circle of insulating tape, and the material picking component then takes out the sensor.

[0022] The material taking component is realized by a manipulator, and the cutting component 3 is realized by a cylinder and a cutter.

[0023] The outer circle of the insulating tape has a certain viscosity to ensure that it can adhere to the sensor surface during the winding process.

[0024] A disc hole that passes through the cavity is opened on the working platform 1. The material changing assembly 2 includes a transposition table 4 rotatably arranged in the disc hole, two through holes eccentrically and symmetrically opened on the transposition table 4, two workstation shafts 5 independently and rotatably arranged in the two through holes, and a winding frame 6 fixed on the working platform 1. A storage cavity 7 for placing a sensor is provided at the top of the workstation shaft 5, and a shaft gear 8 is provided at the bottom of the workstation shaft 5. A disk shaft 9 is fixedly provided at the bottom center of the transposition table 4, and a disk gear 10 is provided at the bottom of the disk shaft 9. A middle frame 11 is provided in the cavity of the casing, and a driving component for driving the disk gear 10 and the shaft gear 8 to rotate is provided on the middle frame 11. A winding wheel 12 is freely rotatable on the winding frame 6, and an insulating tape is wound on the winding wheel 12. After the transposition table 4 rotates, the storage cavity 7 can be shifted to a position where the sensor and the winding wheel 12 are in close contact therewith.

[0025] There are loading and unloading stations and winding stations on the work platform 1. The winding station is where the sensor on the storage cavity 7 is in close contact with the winding wheel 12. When one of the storage cavities 7 is located at the loading and unloading station, the other storage cavity 7 opposite to it will be located exactly at the winding station.

[0026] The normal working conditions are as follows: first, the material picking component clamps a sensor to the storage cavity 7 at the loading and unloading station, and then the storage cavity 7 switches its position to the winding station after the position change table 4 selects 180° to perform the winding work. While the first sensor is winding, the material picking component will not be idle but will remove the front sensor from another storage cavity 7 at the loading and unloading station and place the rear sensor on it.

[0027] The middle frame 11 is provided with a slideway 13, and the driving components include a slider 14 slidably arranged in the slideway 13, a shaft 15 and a second shaft 16 staggered and rotatably arranged on the slider 14, a disk drive gear 17 and a moving wheel 18 fixedly sleeved on the shaft 15, a shaft drive gear 19 and a second moving wheel 20 fixedly sleeved on the second shaft 16, a main driving member 21 fixed on the slider 14, and a reciprocating driving cylinder (not shown in the figure) fixed on the middle frame 11, the output end of the main driving member 21 is connected to the shaft 15, the first moving wheel 18 and the second moving wheel 20 are arranged in the same plane and a transmission belt 22 is tightly arranged between them. The disk drive gear 17 and the shaft drive gear 19 are in different height planes. The disk drive gear 17 and the disk gear 10 are in the same plane and can mesh with each other. The shaft drive gear 19 and the shaft gear 8 are in the same plane and can mesh with each other. The reciprocating drive cylinder drives the slider 14 to reciprocate on the slideway 13. When the disk drive gear 17 is meshed with the disk gear 10, the shaft drive gear 19 and the shaft gear 8 are in a disengaged state. When the shaft drive gear 19 is meshed with the shaft gear 8, the disk drive gear 17 and the disk gear 10 are in a disengaged state.

[0028] When the disk drive gear 17 is meshed with the disk gear 10, the process of the transposition table 4 rotating and switching the workstation is executed; when the shaft drive gear 19 and the shaft gear 8 are engaged, the process of the storage cavity 7 rotating with the sensor to pull the insulating tape on the edge winding wheel 12 for covering is executed.

[0029] Two groups of brake frames 23 are fixed on the middle frame 11, and brake plates 24 are fixed on the brake frames 23 respectively. A reduction plate 25 is fixed on one shaft 15, and two reduction plates 26 are fixed on the second shaft 16. One group of brake plates 24 is located on the moving path of a reduction plate 25 when the disc drive gear 17 and the disc gear 10 are about to engage and can fit with the reduction plate 25, and the other group of brake plates 24 is located on the moving path of the two reduction plates 26 when the shaft drive gear 19 and the shaft gear 8 are engaged and can fit with the two reduction plates 26.

[0030] Because the main drive component 21 is implemented by a general motor and a transmission, the main drive component 21 may not stop rotating actively before the disk drive gear 17 and the disk gear 10 are engaged. In this case, the high-speed rotating disk drive gear 17 and the disk gear 10 are prone to tooth collision during the engagement process, resulting in a reduction in the life of both. Therefore, before the disk drive gear 17 and the disk gear 10 are about to engage, a brake plate 24 on the movement path of a speed reduction plate 25 will fit with a speed reduction plate 25 to achieve speed reduction, and then the drive gear will engage with the disk gear 10 to avoid this problem. The same is true for the shaft drive gear 19 and the shaft gear 8.

[0031] It should be understood that in the claims and description of the present invention, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".

[0032] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
