Description

Technical Field

[0001] The utility model relates to the technical field of sensor disassembly and recycling, in particular to the disassembly processing of shielding wires, and specifically is a sensor shielding wire stripping device. Background Art

[0002] A sensor is a device that receives signals or stimuli and reacts. During actual use, it will be interfered by electromagnetic waves from other electrical devices in the outside world. In order to prevent the influence of such interference on sensor data, sensors are usually shielded by shielding wires. The shielding wire of the sensor is a kind of wire, usually a layer of copper foil wrapped around the sensor data line. In this way, when electromagnetic waves from other devices pass near the sensor, the shielding wire will block them outside, thereby ensuring the accuracy and stability of the sensor data.

[0003] When the sensor is disassembled and recycled, the shielding wire needs to be peeled off, that is, the copper foil layer is peeled off. Generally, a knife is used to make scratches on the copper foil layer along the axis of the sensor, and then a pulling force is applied to the copper foil layer along both sides of the sensor to separate it. Figure 1 As shown, the copper foil layer has a low thickness and can withstand limited tensile force, so it is easy to break during the peeling process. After breaking, the copper foil needs to be pulled again so that force can be applied to the copper foil. Currently, there is no good automated solution to the problem of frequent pulling of the copper foil. Therefore, it is all manually operated and peeled manually, which is inefficient. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a sensor shielding wire stripping device. The device sets a negative pressure adsorption point on the outer ring of the roller for adsorbing and pulling the copper foil. After the roller contacts the copper foil, it adsorbs and pulls the copper foil. When the roller rotates a certain amplitude, its negative pressure port is closed and the negative pressure disappears, thereby separating from the copper foil. As the roller rotates, the copper foil is continuously pulled.

[0005] The specific scheme of the utility model is as follows:

[0006] A sensor shielding wire stripping device, comprising:

[0007] A hollow support member, wherein the size of the through hole in the middle of the support member is greater than or equal to the cross section of the sensor shielding wire;

[0008] A cutting knife carried on the support frame, wherein the cutting blade of the cutting knife is arranged radially inwardly of the middle through hole of the support member, and is used for cutting the sensor shielding wire along the axial direction thereof;

[0009] The roller-type local negative pressure adsorption mechanism carried on the support frame includes:

[0010] A first disc carried on the support frame, a negative pressure cavity is arranged in the first disc, and a negative pressure port penetrating the body is arranged on the first disc;

[0011] A second disc rotatably connected to the first disc, the second disc being annular and having a plurality of negative pressure nozzles arranged radially, each of the negative pressure nozzles being provided with a negative pressure channel penetrating the second disc, one end of the negative pressure channel being connected to the negative pressure nozzle, and the other end being located on a rotating contact surface of the first disc and the second disc;

[0012] A vacuum pumping mechanism, used for vacuuming the negative pressure chamber;

[0013] Among them, the negative pressure port of the first disc is located on the rotating contact surface of the first disc and the second disc. The negative pressure suction nozzle has two states during the rotation of the second disc relative to the first disc, namely, a state in which the negative pressure channel is connected to the negative pressure port and a state in which the negative pressure channel and the negative pressure port are sealed. When the negative pressure suction nozzle contacts the shielding wire, the negative pressure channel is connected to the negative pressure port.

[0014] As a specific implementation of the utility model, there are two or more cutting knives, and all the cutting knives are arranged along the circumference of the middle through hole of the support member.

[0015] As a specific implementation of the utility model, the negative pressure port is located on the circumferential side wall of the first disc.

[0016] As a specific implementation of the utility model, the vacuum mechanism is a vacuum pump.

[0017] Compared with the existing technology, it has the following advantages:

[0018] The stripping device of the utility model is provided with a roller-type local negative pressure adsorption mechanism. After the negative pressure suction nozzle contacts the shielding wire, the negative pressure channel is connected with the negative pressure chamber, and the negative pressure suction nozzle can tightly adsorb the shielding wire, thereby guiding the shielding wire to move to both sides of the sensor as the second disk rotates, thereby realizing stripping. When the negative pressure channel is separated from the negative pressure port, negative pressure is no longer drawn to the negative pressure suction nozzle, and the negative pressure of the negative pressure suction nozzle gradually disappears, thereby releasing the shielding wire. In this cycle, the shielding wire can be continuously adsorbed, pulled to both sides of the sensor, and released, thereby realizing continuous stripping and improving operating efficiency.

[0030] The present invention will be further described in detail below in conjunction with the embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0031] The sensor shielding wire stripping device of the utility model is mainly used to strip the shielding wire of the sensor. In order to facilitate the understanding of the specific scheme of the utility model, the operation of stripping the existing sensor shielding wire is briefly described here. Please refer to the following Figure 1 The shielding wire of the sensor is usually a layer of copper foil with a relatively thin thickness. When stripping, a cutting knife 200 is used to split the shielding wire (copper foil layer) 1 along the sensor axis, and then a pulling force is applied to the shielding wire 1 along both sides of the sensor to assist in separating it from the data wire 2 in the sensor. However, the shielding wire 1 is thin and has limited tensile strength, so it is easy to break during the stripping process. After breaking, the shielding wire 1 needs to be re-pulled to apply lateral pulling force to the shielding wire attached to the data wire 2. At present, most of this type of stripping operations are manually operated, and manual stripping is inefficient, and the stripping efficiency will be further reduced as the number of breaks increases.

[0032] Example

[0033] Please refer to Figure 2 to Figure 4, which shows the structure of a specific embodiment of the sensor shielding wire stripping device of the utility model. The sensor shielding wire stripping device of the utility model comprises a support member 100, a cutter 200, and a roller-type local negative pressure adsorption mechanism 300, wherein the support member 100 is hollow, such as Figure 4 The cylindrical shape shown in the figure, the size of the middle through hole of the support member 100 is greater than or equal to the cross section of the sensor shielding wire 1, so that the shielding wire 1 can pass through the middle through hole 110 of the support member 100, and thus be cut in the middle through hole 110; the cutting knife 200 is carried on the support frame 100, and the blade of the cutting knife 200 is arranged radially inwardly along the middle through hole 110 of the support member 100, as shown in FIG. Figure 3As shown, it is used to cut the shielding line 1 along its axial direction; the roller-type local negative pressure adsorption mechanism 300 is also carried on the support frame 100, which includes a first disc 310 and a second disc 320. The first disc 310 is carried on the support frame 100, and a negative pressure chamber 311 is arranged in the first disc 310. In specific implementation, the negative pressure chamber 311 can be evacuated by a vacuum pumping mechanism to make the pressure in the negative pressure chamber 311 lower than the normal pressure (atmospheric pressure). For example, in some embodiments, a vacuum pump can be arranged to evacuate the negative pressure chamber 311, and the first disc 3 10 is provided with a negative pressure port 312 running through the body, the first disc 310 cannot rotate to prevent the negative pressure port 312 from rotating, the second disc 320 is rotatably connected to the first disc 310, the second disc 320 is annular and has a plurality of negative pressure nozzles 321 arranged along its radial direction, each negative pressure nozzle 321 is provided with a negative pressure channel 322 running through the second disc 320, one end of the negative pressure channel 322 is connected to the negative pressure nozzle 321, and the other end is located on the rotating contact surface of the first disc 310 and the second disc 320; the negative pressure of the first disc 310 The opening 312 is located on the rotating contact surface of the first disk 310 and the second disk 320. The negative pressure nozzle 321 has two states during the rotation of the second disk 320 relative to the first disk 310, namely, the state in which the negative pressure channel 322 is connected to the negative pressure opening 312 and the state in which the negative pressure channel 322 is separated from the negative pressure opening 312. When the negative pressure nozzle 312 contacts the shielding wire 311, the negative pressure channel 322 and the negative pressure opening 312 are in a connected state. At this time, the negative pressure cavity 311 is connected to the negative pressure nozzle 321, and the negative pressure nozzle 321 absorbs the shielding wire. The outer wall of the shielding wire 1 is guided to move to both sides of the sensor as the second disc 320 rotates, and the stripping is realized. When the second disc 320 rotates a certain amplitude relative to the first disc 310, the negative pressure channel 322 is separated (separated) from the negative pressure port 312, and the negative pressure chamber 312 no longer draws negative pressure to the negative pressure suction nozzle 321, and the negative pressure at the negative pressure suction nozzle 321 gradually disappears, thereby releasing the shielding wire 1. In this way, the outer shell of the shielding wire 1 can be adsorbed, pulled to both sides of the sensor, and released in a cycle, so as to realize continuous stripping and improve the operation efficiency. In the specific arrangement, the cutting knife 200 can be arranged upstream of the roller-type local negative pressure adsorption mechanism 300, so that cutting can be performed first, and then adsorption and stripping can be performed.

[0034] In some embodiments, there are two or more cutting knives 200, and all the cutting knives are arranged along the circumference of the middle through hole of the support member 100, such as Figure 1 In the illustrated embodiment, two cutters 200 are provided, and the two cutters 200 are symmetrically arranged along the circumference of the shielded wire 1 .

[0035] In some embodiments, Figure 5As shown, the negative pressure port 312 is located on the circumferential side wall of the first disc 310. In order to accelerate the speed at which the negative pressure of the negative pressure nozzle 312 disappears after the negative pressure channel 322 is separated from the negative pressure port 312, so as to release the shielding wire more quickly, a vent hole 313 is provided on the first disc, and the negative pressure channel 322 is connected to the vent hole 313 after being separated from the negative pressure port 312, thereby destroying the negative pressure state in the negative pressure nozzle 312.

[0036] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present invention should be covered within the protection scope of the present invention.
