Silicone tubes are divided into two categories: hard tubes and soft tubes. In the production process of silicone hard tubes, silicone tubes of different diameters need to be classified and selected. The classification method includes diameter classification; The existing classification methods mostly use manual classification and selection. The principle is usually to set up multiple workstations on both sides of the conveyor table, and manually pick up the silicone tubes on the conveyor table and classify the silicone tubes in a specified diameter range by visual inspection. Therefore, most of them need to use calipers to accurately measure their diameters, and then pick them up to the designated conveying equipment according to the diameter parameters. This method will waste a lot of manpower in the process of classifying silicone tubes, make the staff easily fatigued, and cause the caliper to be taken irregularly, thereby reducing the accuracy of silicone tube classification, and also lead to low classification efficiency of silicone tubes.

When the silicone tubes reach the front of the laser diameter gauge 25, the silicone tubes are taken and then placed above the two base frames 26, and the silicone tubes are passed through the detection area of ​​the laser diameter gauge 25. At this time, the third motor 39 is started, and the first driven gear 40 can be driven to rotate the fixed tube 41, and the two second driven gear blocks 45 can drive the two second driven gear blocks 46 to rotate synchronously through the meshing effect, and further, the two first rotating shafts 57 can drive the two driving gears 48 to rotate synchronously in the two empty slots 27. When the driving gear 48 rotates, the two racks 49 can pull the two support plates 28 to move toward each other on the bottom frame 26 through meshing, so that the plurality of second clamping blocks 32 can position the silicone tube to be tested, so that the silicone tube can be more accurately tested in the subsequent process. At this time, the laser diameter gauge 25 can quickly and accurately measure the diameter of the silicone tube and transmit the measured diameter data to the control system of the device (the laser diameter gauge 25 is mainly based on the principle of interaction between the laser beam and the object to be tested. When the laser beam is irradiated on the surface of the object to be tested, if the object is reflected or scattered, the instrument calculates the geometric size of the object by analyzing the reflected or scattered laser signal); In the above process, since the diameters of the silicone tubes are different, when the second motor 33 is clamping the silicone tube, the second clamping plate 29 will cause the second pressure block to provide a pressure to the second pressure sensor 37. When the pressure value detected by the second pressure sensor 37 reaches the specified value, a locking signal will be transmitted to the control system of the third motor 39, so that the third motor 39 can be quickly locked to prevent the silicone tube to be detected from being squeezed and damaged.

[0015] The control system calculates the target conveying platform (first conveying platform 2, second conveying platform 3 or third conveying platform 4) where the silicone tube should be sorted according to the received silicone tube diameter data, and then the first motor 7 is started, and the first motor 7 drives the first screw 8 at its output end to rotate. Since the first screw 8 is threadedly connected to the top seat 5, and the top seat 5 can only move in the horizontal direction under the restriction of the cross bar 9, the top seat 5 will drive the entire lifting assembly to move to the top of the silicone tube to be sorted along the cross bar 9 under the drive of the first screw 8; Next, the first cylinder 6 in the lifting assembly is started, pushing the frame 10 and the top frame 11 to move downward, and the top blocks 16 on the side seats 12 at both ends of the top frame 11 are lowered together with the top frame 11, and the grabbing blocks 17 at the bottom of the top blocks 16 are gradually close to the silicone tube, and then the second cylinder 13 is started, which can make the top plate 14 drive the two L-shaped plates 15 to descend, and further enable multiple drives to slide in the specified inclined groove 18, so that the two grabbing blocks 17 can be synchronously brought close, when the first clamping block 22 contacts the silicone tube, the first clamping plate 21 inside the grabbing block 17 is squeezed by the silicone tube, and the first support rod outside the first clamping plate 21 begins to compress the first spring in the first groove 20, and at the same time, the first pressure block squeezes the first pressure sensor 24 in the first positioning groove 23. After the first pressure sensor 24 senses that the pressure value reaches the specified parameter, it immediately converts the pressure signal into an electrical signal and transmits it to the control system on the second cylinder 13, which can quickly lock the second cylinder 13, thereby preventing the silicone tube from being squeezed and damaged during the grabbing process; The first cylinder 6 is started again, this time to lift the lifting assembly clamping the silicone tube so that the silicone tube is located above the laser diameter measuring instrument 25, and then the first motor 7 is started again to move the lifting assembly to the top of the corresponding target conveying platform (the first conveying platform 2, the second conveying platform 3 or the third conveying platform 4) according to the previously calculated path; The first cylinder 6 descends again and places the silicone tube on the target conveying platform. At this time, the second cylinder 13 moves in the opposite direction to raise the lifting rod, and the top plate 14 rises to drive the L-shaped plate to rise, so that the first clamping block 22 can release the silicone tube, completing the sorting and classification process of the silicone tube. After that, each component is reset and waits for the next inspection and classification. With the help of a laser diameter gauge 25, the diameter of the silicone tube is measured with high precision, and the measurement data can be transmitted to the control system in real time. The control system accurately calculates and controls the actions of the lifting component and the positioning component based on these data, so as to accurately sort the silicone tube to the corresponding first conveyor platform 2, the second conveyor platform 3 or the third conveyor platform 4. Compared with traditional manual sorting, this automated sorting method greatly improves the efficiency and accuracy of sorting, effectively reduces the errors caused by human factors during manual sorting, and improves the quality stability of product classification on the silicone tube production line.

[0016] In this embodiment, a plurality of fixing frames 30 are symmetrically arranged at both ends of the second clamping plate 29, a fixing shaft 31 is rotatably arranged on the fixing frame 30, the second clamping block 32 is fixed at both ends of the fixing shaft 31, a second motor 33 is arranged on the top of the second clamping plate 29, and a driving gear disc 34 is arranged at the output end of the second motor 33, and the driving gear disc 34 is meshed with one of the fixing shafts 31; Through the fixed frame 30 provided, the fixed shaft 31 can drive the second clamping block 32 to rotate. Since the driving gear disc 34 at the output end of the second motor 33 is meshed with the fixed shaft 31, when the second motor 33 is started, it can be ensured that the second clamping block 32 drives the silicone tube to rotate flexibly under support, so that the angle of the silicone tube can be adjusted according to the shape and positioning requirements of the silicone tube later. The intermittent start of the second motor 33 can be temporarily adjusted. When the silicone tube rotates in the gap, the laser diameter gauge 25 can perform multi-directional diameter detection on it, which can further improve the classification accuracy of the silicone tube in this structure; In this embodiment, two cavities 47 are set symmetrically on the classification table 1 for the laser diameter measuring instrument 25, the base frame 26 can slide inside the cavity 47, a base 50 is set at the lower end of the base frame 26, a fourth motor 51 is set at the lower end of the classification table 1, and a second rotating shaft is set at the output end of the fourth motor 51, two second screws 52 with reverse thread structures are symmetrically set on the second rotating shaft, and the two second screws 52 respectively penetrate the two bases 50, a transfer tube 44 is rotatably set on the second box body, and the second driving gear block 45 is fixed at one end of the transfer tube 44, and the inner of the fixed tube 41 is fixed to the outer end of the fixed tube 41.

The locking rods are threadedly connected to the top plate 14 and the top frame 11. By controlling the fourth motor 51 at the lower end of the classification table 1, the second shaft is rotated. Since the second screws 52 of the two reverse thread structures symmetrically arranged on the second shaft respectively penetrate the two bases 50 at the lower end of the bottom frame 26, the relative positions of the two bottom frames 26 in the two cavities 47 symmetrically arranged by the laser diameter measuring instrument 25 on the classification table 1 can be adjusted to determine the appropriate initial spacing to adapt to the placement and positioning of silicone tubes of different lengths. In this process, the cross section of the adapter groove 43 is as shown in FIG. Fig.12 As shown, when the base frame 26 is moving, the adapter block will be correspondingly extended and retracted inside the adapter groove 43, and when the fixed tube 41 is rotating, the adapter tube 44 will not slip. When the position of the base frame 26 is adjusted, the locking rod is rotated, and the locking rod no longer limits the first connecting plate and the second connecting plate through the effect of the threaded structure, and then the designated first connecting plate and the second connecting plate are pulled, so that the position of the L-shaped plate 15 and the side seat 12 can be temporarily adjusted, which is convenient for grabbing silicone tubes of different lengths, and can improve the applicability of the present structure. A bottom plate 55 is provided on one side of the bottom frame 26, a side plate 56 located above the bottom plate 55 is provided on one side of the side seat 12, a through hole is provided on the side plate 56, a groove is provided on the bottom plate 55, and the groove is located directly below the through hole; When the locking rod is in the loosened state, take the designated cylindrical rod and make it pass through the through hole and insert it into the groove.
