DETAILED DESCRIPTION

[0018] 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.

[0019] like Figure 1 As shown, the insulation layer winding equipment of the special pressure sensor for orthosis comprises a casing part 2 having a cavity inside and a working platform 1 on the top, and the following parts arranged on the working platform 1, namely: a material changing part for switching the sensor station and winding the insulating tape on the sensor, a material taking part (not shown in the figure) for taking the sensor to be processed from the front conveyor belt to the material changing part and taking the finished processed sensor from the material changing part to the rear conveyor belt, and a cutting part for cutting off the edge of the sensor with the insulation layer wound by the material changing part; the material changing part 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 part.

[0020] The winding process of each sensor is as follows: the material taking part places the sensor to be processed taken from the front conveyor belt on the working platform 1 at the loading and unloading station, and then the material changing part winds the insulating tape on the sensor, and then the cutting part cuts off the sensor that has been bent with at least one circle of insulating tape, and the material taking part then takes the sensor to the rear conveyor belt.

[0021] 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.

[0022] In addition, the front conveyor belt refers to the conveyor belt that transports sensors that have not completed winding the insulation layer to the winding device one by one, and the rear conveyor belt refers to the conveyor belt that sends sensors that have completed winding work from the winding device one by one.

[0023] The material picking part is generally completed by a highly versatile manipulator on the market, as long as the manipulator's gripper meets the specifications of the gripping sensor.

[0024] like Figure 2 and Figure 3As shown, a disc hole penetrating the cavity is provided on the working platform 1, the material changing part comprises a disc body 3 rotatably arranged in the disc hole, two axial holes eccentrically and symmetrically provided on the disc body 3, two shaft members 4 independently rotatably arranged in the two shaft holes, and a winding frame 5 fixed on the working platform 1, a storage body 6 for placing a sensor is provided at the top of the shaft member 4, a shaft gear 7 is provided at the bottom of the shaft member 4, a disc shaft 8 is fixedly provided at the bottom center of the disc body 3, a disc gear 9 is provided at the bottom of the disc shaft 8, a middle frame 10 is provided in the cavity of the casing part 2, and a driving component for driving the disc gear 9 and the shaft gear 7 to rotate is provided on the middle frame 10, a winding wheel 11 is freely rotatable on the winding frame 5, an insulating tape is wound on the winding wheel 11, and after the disc body 3 rotates, the storage body 6 can be shifted to a position where the sensor thereon is in close contact with the winding wheel 11.

[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 body 6 is in close contact with the winding wheel 11. When one of the storage bodies 6 is located at the loading and unloading station, the other storage body 6 opposite to it will be located at the winding station.

[0026] The normal working conditions are as follows: first, the material-retrieving part clamps a sensor onto the storage body 6 at the loading and unloading station, and then the storage body 6 switches position to the winding station after the disc body 3 selects 180° to perform the winding work. While the first sensor is winding, the material-retrieving part will not be idle but will remove the front sensor from another storage body 6 at the loading and unloading station and place the rear sensor on it.

[0027] The material taking part can be a single manipulator that performs loading and unloading simultaneously, or two manipulators that perform loading and unloading independently.

[0028] The middle frame 10 is provided with a slideway, and the driving components include a slider 12 slidably arranged in the slideway, a first shaft 13 and a second shaft 14 staggered and rotatably arranged on the slider 12, a disk drive gear 24 and a first moving wheel 15 fixedly sleeved on the first shaft 13, a shaft drive gear 25 and a second moving wheel 16 fixedly sleeved on the second circle, a main driving member 17 fixed on the slider 12, and a reciprocating driving member (not shown in the figure) fixed on the middle frame 10, wherein the output end of the main driving member 17 is connected to the first shaft 13, and the first moving wheel 15 is fixedly sleeved on the second circle. The disk drive gear 24 and the shaft drive gear 25 are arranged in the same plane as the disk gear 9 and can mesh with each other. The shaft drive gear 25 and the shaft gear 7 are in the same plane and can mesh with each other. The reciprocating drive member drives the slider 12 to reciprocate on the slideway. When the disk drive gear 24 is meshed with the disk gear 9, the shaft drive gear 25 and the shaft gear 7 are in a disengaged state. When the shaft drive gear 25 is meshed with the shaft gear 7, the disk drive gear 24 and the disk gear 9 are in a disengaged state.

[0029] The main drive component 17 can use a general motor and a transmission. When the disk drive gear 24 is engaged with the disk gear 9, the disk body 3 is rotated to switch the working position. When the shaft drive gear 25 and the shaft gear 7 are engaged, the storage body 6 is rotated with the sensor to pull the insulating tape on the edge of the winding wheel 11 for covering.

[0030] Two sets of brake frames 18 are fixed on the middle frame 10, and brake plates 19 are fixed on the brake frames 18 respectively. A first reduction plate 26 is fixed on the first shaft 13, and a second reduction plate 27 is fixed on the second shaft 14. One set of brake plates 19 is located on the moving path of the first reduction plate 26 when the disc drive gear 24 and the disc gear 9 are about to engage and can fit with the first reduction plate 26, and the other set of brake plates 19 is located on the moving path of the second reduction plate 27 when the shaft drive gear 25 and the shaft gear 7 are engaged and can fit with the second reduction plate 27.

[0031] Because the main drive component 17 is implemented by a general motor and a transmission, the main drive component 17 may not stop rotating actively before the disk drive gear 24 is meshed with the disk gear 9. In this case, the high-speed rotating disk drive gear 24 and the disk gear 9 are prone to tooth collision during the meshing process, resulting in a reduction in the life of both. Therefore, before the disk drive gear 24 and the disk gear 9 are about to mesh, the brake plate 19 on the movement path of the first speed reduction plate 26 will fit with the first speed reduction plate 26 to achieve speed reduction, and then the drive gear will mesh with the disk gear 9 to avoid this problem. The same is true for the shaft drive gear 25 and the shaft gear 7.

[0032] The shaft gear 7, the shaft drive gear 25 and the disk drive gear 24 are all small gears of the same specification, the disk gear 9 is a large gear, and the transmission ratio of the small gear to the large gear is 2:1.

[0033] Under normal working conditions: the disc body 3 rotates 0.5 circles to complete the 180-degree station switching function, and the shaft 4 rotates 1 circle to complete the outer circumference of the sensor being 100% covered by the insulating tape. Therefore, in order to facilitate design and production, the shaft gear 7, the shaft drive gear 25, and the disk drive gear 24 can be made into small gears of the same specifications. Then the transmission efficiency of the shaft gear 7 and the shaft drive gear 25 is 1:1, and the transmission efficiency of the disk drive gear 24 and the disk gear 9 is 2:1, so that the quantity can be fully controlled.

[0034] The reciprocating parts are realized by any one of air cylinder, oil cylinder and screw rod in conjunction with PLC control system.

[0035] The outer ring of the disc body 3 is provided with a circle of first limiting rings, and the inner circumference of the disc hole is provided with a circle of first limiting ring grooves corresponding to the size of the first limiting rings, and the first limiting rings are arranged in the first limiting ring grooves. The first limiting ring grooves and the first limiting ring grooves are usually not directly slidably connected, and bearings are provided to enable the disc body 3 to rotate smoothly in the disc hole, and the existence of the first limiting ring grooves and the first limiting ring grooves can make the disc body 3 only rotate in the disc hole and not fall out.

[0036] The outer ring of the shaft 4 is provided with a circle of second limiting rings, and the inner circumference of the shaft hole is provided with a circle of second limiting ring grooves corresponding to the size of the second limiting rings, and the second limiting rings are arranged in the second limiting ring grooves. The second limiting ring grooves and the second limiting ring grooves are usually not directly slidably connected, and bearings are provided to enable the shaft 4 to rotate smoothly in the shaft hole, and the existence of the first limiting ring groove and the first limiting ring groove can make the shaft 4 only rotate in the shaft hole without disengaging.

[0037] A tensioning frame 20 is also slidably provided on the winding frame 5 , and a tensioning wheel 21 is freely rotatably provided on the tensioning frame 20 . The insulating tape passes through the tensioning wheel 21 and then is wound on the winding wheel 11 .

[0038] The cutting part includes a cutting frame 22 fixed on the working platform 1, a switching drive member fixed on the cutting frame 22 (hidden in the cutting frame 22 in the figure), and a cutting blade 23 fixed at the output end of the switching drive member. The cutting blade 23 can pass between the sensor and the winding wheel 11 to cut the insulating tape.

[0039] The switching drive is realized by the cylinder in conjunction with the PLC controller.
