[0022] As a technical optimization solution of the present invention, the fixing mechanism includes an electric extension rod 16 and an abutting plate 17. A plurality of abutting plates 17 are evenly arranged on the outer side of the rotating rod 15 along the circumferential direction.

The installation end of the electric extension rod 16 faces the rotating rod 15, and the installation end of the electric extension rod 16 is connected to the rotating rod 15. By driving the abutting plate 17 to extend through the electric extension rod 16, so that the abutting plate 17 abuts against the inner wall of the adhesive tape roll fixing ring, the fixing of the adhesive tape roll can be realized, and at the same time, it is also convenient for the device to automatically lower the adhesive tape roll fixing ring.

[0023] As a technical optimization solution of the present invention, a moving chute 7 is opened on the mounting plate 1 near the moving rod 3.

[0025] As a technical optimization solution of the present invention, the detection mechanism includes a movable plate 13 and a pressure sensor 33. A fourth slot 30 is opened on the side of the second connecting plate 6 far from the moving rod 3. The movable plate 13 is slidably installed inside the fourth slot 30. An abutting roller 14 is rotatably installed on the side of the movable plate 13 far from the second connecting plate 6. A pressure sensor 33 is installed at the bottom end of the inner wall of the fourth slot 30. A spring telescopic rod 34 is installed on the side of the movable plate 13 facing the pressure sensor 33. The end of the spring telescopic rod 34 far from the movable plate 13 abuts against the pressure sensor 33. The vibration generated during the unwinding process of the baseband will be transmitted to the movable plate 13 through the abutting roller 14. By absorbing the vibration value of the movable plate 13 by the spring telescopic rod 34, the damping effect during the unwinding process of the adhesive tape baseband can be realized, thereby increasing the unwinding stability of the adhesive tape baseband, preventing the adhesive tape baseband from shifting during transmission due to its own vibration, and increasing the unwinding stability of the adhesive tape baseband; The abutting roller 14 rotates during the unwinding of the self-adhesive base tape. By means of the movable plate 13 sliding inside the second connecting plate 6 and pressing the pressure sensor 33 through the spring telescopic rod 34, the pressure sensor 33 can measure the extrusion force between the abutting roller 14 and the self-adhesive base tape. When wrinkles occur on the surface of the self-adhesive base tape, the pressure value measured by the pressure sensor 33 is bound to change and exceed the preset pressure value change range. At this time, combined with the shooting of the surface of the self-adhesive base tape by the camera 28, it can enable the staff to more quickly find the defective part on the self-adhesive base tape and process it, increasing the usability of the device.

[0026] As a technical optimization scheme of the present invention, stable sliding grooves 31 are provided on the inner walls at both ends of the fourth slotted groove 30. A stable sliding block 32 is slidably installed inside the stable sliding groove 31. The side of the stable sliding block 32 close to the movable plate 13 is connected to the movable plate 13. By the sliding of the stable sliding block 32 in the stable sliding groove 31, the sliding stability of the movable plate 13 inside the fourth slotted groove 30 can be increased.

[0027] As a technical optimization scheme of the present invention, the auxiliary mechanism includes a third connecting plate 9. Two second electric telescopic rods 24 are embedded and installed on the side of the first connecting plate 5 close to the second connecting plate 6. The installation end of the second electric telescopic rod 24 is connected to the second connecting plate 6. The two first connecting plates 5 on each moving rod 3 are taken as a group. Third connecting plates 9 are movably provided on the sides of the two groups of first connecting plates 5 facing each other. A third electric telescopic rod 25 is embedded and installed on the first connecting plate 5. The telescopic end of the third electric telescopic rod 25 is connected to the third connecting plate 9. By the way of the third connecting plate 9 clamping the self-adhesive tape fixing ring and combining with the movement of the moving rod 3, the automatic lowering of the self-adhesive tape fixing ring can be realized.

[0028] As a technical optimization scheme of the present invention, an air inlet groove 29 is provided inside the third connecting plate 9. An air inlet hole 26 is provided on the side of the third connecting plate 9 away from the second connecting plate 6. The air inlet hole 26 is communicated with the air inlet groove 29. A plurality of air outlet holes 27 are uniformly penetrated and provided on the inner wall of the air inlet groove 29 on the side away from the first connecting plate 5. When the negative ion fan connected to the air inlet hole 26 is started, negative ion air enters the inside of the air inlet groove 29 and then is ejected through the air outlet holes 27. By the way of ejecting negative ion air through the air outlet holes 27, the floating dust on the self-adhesive base tape can be blown off, increasing the cleanliness of the self-adhesive base tape. By this operation method, the quality of subsequent glue application to the self-adhesive base tape can be increased, increasing the usability of the device.

[0029] As a technical optimization solution of the present invention, a plurality of cameras 28 are evenly embedded and installed on the side of the third connecting plate 9 above the rotating rod 15 away from the first connecting plate 5. A second slot 10 is formed on the side of the third connecting plate 9 below the rotating rod 15 away from the first connecting plate 5. A lifting plate 11 is slidably installed inside the second slot 10. A first electric telescopic rod 18 is installed at the bottom end of the inner wall of the second slot 10. The telescopic end of the first electric telescopic rod 18 is connected to the lifting plate 11. A third slot 19 is formed on the side of the lifting plate 11 away from the first electric telescopic rod 18. A rotating plate 20 is movably installed inside the third slot 19. Rotating motors 21 are embedded at both ends of the rotating plate 20. The installation end of the rotating motor 21 is connected to the inner wall of the third slot 19. A plurality of rollers 12 are evenly rotatably installed on the side of the rotating plate 20 away from the first electric telescopic rod 18. The camera 28 can realize the shooting of the baseband during the non-drying glue unwinding process. Combining the detection of the baseband by the pressure sensor 33, the combined detection method can increase the accuracy of the detection result of the device function. At the same time, the camera 28 can provide accurate operation trajectory support for the device when the device operates different functions. By driving the lifting plate 11 to rise and fall through the first electric telescopic rod 18, the rollers 12 are abutted against the non-drying glue roll to provide moving support for the non-drying glue roll. When the non-drying glue roll needs to be fixed after adjusting its position, the position of the lifting plate 11 is adjusted so that the rollers 12 do not abut against the non-drying glue roll. At this time, the non-drying glue roll can be stably placed at the third connecting plate 9. By driving the rotating plate 20 to rotate through the rotating motor 21, the abutting angle between the rollers 12 and the non-drying glue roll can be adjusted, making the movement of the non-drying glue roll on the rollers 12 smoother.

[0030] When the present invention is in use, the electrical equipment used in the present device is powered by connecting to an external power supply through wires. The present device controls the electrical equipment in the device by setting a control system. The pressure sensor 33 and the conveyor belt 22 used in the present device are both existing mature technologies, so no more elaboration will be made on them here. The horizontal height of the top of the conveyor belt 22 is higher than the horizontal height of the bottom inner wall of the first slot 2. When the device is in use, the air inlet 26 is connected to a preset negative ion blower outside the device through a conduit. The connection method between the conduit, the negative ion blower and the air inlet 26 and the negative ion blower are both existing mature technologies, so no more elaboration will be made on them here. The reserved length of the conduit is sufficient for the displacement of the third connecting plate 9 to perform multiple functions. Rubber coating layers are provided on the outer sides of the third connecting plate 9, the rollers 12 and the abutting roller 14.

[0031] When the device is in use, the non - adhesive tape roll without glue is sleeved outside the rotating rod 15. By means of the electric extension rod 16 driving the abutting plate 17 to extend, the abutting plate 17 abuts against the inner wall of the non - adhesive tape roll fixing ring to complete the fixation of the non - adhesive tape roll. Subsequently, the staff pulls out the head of the base tape in the non - adhesive tape roll, and the pulling direction is Figure 1 in the direction starting from the rotating rod 15 to the first slot 2. By means of the rotating motor 23 driving the rotating rod 15 to rotate, the unwinding of the non - adhesive tape roll can be completed. Subsequently, the staff winds the pulled - out head of the non - adhesive tape roll on the non - adhesive tape coating machine. The non - adhesive tape coating machine is an existing mature technology, so it will not be elaborated too much here.

[0032] After the base tape of the non - adhesive tape roll is installed, by sliding the moving electric slider 8 in the moving chute 7, the moving rod 3 moves on the mounting plate 1 towards the first slot 2. After the moving rod 3 moves to the preset use position, by means of the electric lifting rod 4 driving the second connecting plate 6 to extend, the two second connecting plates 6 move towards the base tape of the non - adhesive tape roll until the two abutting rollers 14 respectively abut against the top and bottom of the base tape of the non - adhesive tape roll. At this time, the side of the third connecting plate 9 away from the first connecting plate 5 does not contact the base tape of the non - adhesive tape roll. The camera 28 can take pictures of the surface condition of the non - adhesive base tape and transmit it to the background control system. The abutting rollers 14 rotate during the unwinding process of the non - adhesive base tape, and by means of the movable plate 13 sliding inside the second connecting plate 6 and the spring telescopic rod 34 squeezing the pressure sensor 33, the pressure sensor 33 can measure the extrusion force between the abutting roller 14 and the non - adhesive base tape. When there are wrinkles on the surface of the non - adhesive base tape, the measured pressure value of the pressure sensor 33 is bound to change and exceed the preset pressure value change range. At this time, combined with the pictures taken by the camera 28 of the surface of the non - adhesive base tape, it can enable the staff to more quickly find the defective parts on the non - adhesive base tape and deal with them, increasing the convenience of using the device.

[0033] During the unwinding process of the non - adhesive base tape, by means of the abutting roller 14 abutting against the surface of the base tape and the movable plate 13 sliding inside the fourth slot 30, the vibration generated during the unwinding process of the base tape will be transmitted from the abutting roller 14 to the movable plate 13. By absorbing the vibration value of the movable plate 13 through the spring telescopic rod 34, the damping effect during the unwinding process of the non - adhesive base tape can be realized, thereby increasing the unwinding stability of the non - adhesive base tape, preventing the non - adhesive base tape from shifting during transmission due to its own vibration, and increasing the unwinding stability of the non - adhesive base tape.

[0034] During the unwinding process of the self-adhesive roll, the negative ion blower connected to the air inlet hole 26 starts, and the negative ion wind enters the interior of the air inlet groove 29 and then is ejected through the air outlet hole 27. By ejecting the negative ion wind outward through the air outlet hole 27, the floating dust on the self-adhesive base tape can be blown off, increasing the cleanliness of the self-adhesive base tape. Through this operation method, the quality of subsequent glue coating on the self-adhesive base tape can be improved, and the usability of the device is increased.

[0035] After the unwinding of the self-adhesive roll on the rotating rod 15 is completed, it is necessary to perform a roll-changing operation on the self-adhesive roll on the rotating rod 15. At this time, the device operates according to the following operation steps. First, the two moving rods 3 move again to Figure 1 the usage state shown in the figure. Subsequently, the second connecting plate 6 above the rotating rod 15 moves towards the rotating rod 15, and the second connecting plate 6 moves to the preset usage position. The second electric telescopic rod 24 drives the first connecting plate 5 to move away from the second connecting plate 6 and move to the preset usage position. Subsequently, the third electric telescopic rod 25 drives the third connecting plate 9 to move away from the first connecting plate 5 until the bottom of the third connecting plate 9 moves to the horizontal height position below the central axis of the rotating rod 15. At this time, the second electric telescopic rod 24 drives the first connecting plate 5 to retract, so that the third connecting plate 9 abuts against the outer wall of the self-adhesive roll fixing ring. Subsequently, the abutting plate 17 moves towards the rotating rod 15 and no longer supports and fixes the self-adhesive roll fixing ring. The fourth electric telescopic rod 35 drives the moving rod 3 to move away from the mounting plate 1. During the movement of the moving rod 3, the third connecting plate 9 clamps out the remaining self-adhesive roll fixing ring on the rotating rod 15. After the moving rod 3 moves to the preset position, the two first connecting plates 5 move away from each other, and the clamped self-adhesive roll fixing ring can be lowered, completing the automatic removal of the remaining self-adhesive roll fixing ring on the rotating rod 15. Subsequently, the moving rod 3, the first connecting plate 5, and the third connecting plate 9 perform a reset movement; Subsequently, both moving rods 3 move to the preset use positions at the first slot 2. The third connecting plate 9 below the rotating rod 15 moves to the preset use position driven by the second electric telescopic rod 24 and the third electric telescopic rod 25. And by the way of driving the lifting plate 11 to lift through the first electric telescopic rod 18, the lifting plate 11 moves out of the interior of the second slot 10. Then, according to the size of the self-adhesive roll processed by the device, the rotation motor 21 is controlled to drive the rotating plate 20 to rotate, so that the rotating plate 20 rotates to the preset use angle. At the same time, the uncoated self-adhesive roll is conveyed on the conveyor belt 22, and the length direction of the self-adhesive roll fixing ring is horizontal with the length direction of the rotating rod 15. Through the conveyance of the conveyor belt 22, when the self-adhesive roll passes through the first slot 2, the outer side of the self-adhesive roll abuts against the top of the roller 12. When the self-adhesive roll detaches from the conveyor belt 22, the self-adhesive roll is located on the tops of the two third connecting plates 9 below the mounting plate 1. Subsequently, the two third connecting plates 9 above the mounting plate 1 can adjust the position of the self-adhesive roll by clamping the self-adhesive roll and moving away from the mounting plate 1. After the position of the self-adhesive roll is adjusted, the two third connecting plates 9 above the mounting plate 1 abut against the outer side of the self-adhesive roll. The first electric telescopic rod 18 drives the lifting plate 11 to retract, so that the bottom of the self-adhesive roll abuts against the tops of the two third connecting plates 9 below the mounting plate 1. Subsequently, both moving rods 3 move away from the mounting plate 1. After moving to the preset positions, the two moving rods 3 move towards the rotating rod 15 until the central position of the self-adhesive roll fixing ring is aligned with the central position of the rotating rod 15. When the moving rods 3 move close to the mounting plate 1 and the fixing ring of the self-adhesive roll is sleeved on the rotating rod 15, the abutting plate 17 abuts against the inner wall of the self-adhesive roll fixing ring to complete the fixing of the self-adhesive roll. Subsequently, the third connecting plate 9 makes a reset movement. Through this operation method, the automatic roll change of the self-adhesive roll can be completed, which increases the use convenience of the device.
