Description

Technical Field

[0001] This invention relates to the field of insulating winding technology, specifically to a high-voltage busbar insulating winding device with release film recycling function. Background Technology

[0002] In the operation and maintenance of high-voltage equipment in substations, high-voltage busbars generally use card-type insulating sleeves for basic insulation protection. However, for the splicing gaps of the card-type insulating sleeves and the locations of damaged defects in the sleeves, it is necessary to reinforce the insulation by wrapping insulating tape to ensure the operational safety and insulation stability of the high-voltage busbars and avoid safety hazards such as leakage and discharge.

[0003] Currently, specialized insulation winding equipment for high-voltage busbars has been publicly disclosed in the industry. For example, patent document CN121448878A discloses a high-voltage busbar insulation winding machine. This equipment mainly includes a support with a C-shaped opening, a C-shaped rotating component that can rotate around the C-shaped opening, a mounting plate fixedly installed on the rotating component, and a tape shaft for placing the tape roll rotatably mounted on the mounting plate. The support is equipped with a positioning and cutting mechanism. During operation, the equipment is lifted to the busbar working position by an insulating operating rod, so that the busbar fits into the center of the rotating component. The circumferential rotation of the rotating component drives the tape roll to release the insulating tape, automatically completing the tape winding operation at the defective position of the busbar. The positioning and cutting mechanism can realize the positioning and cutting of the tape, replacing the traditional manual winding method and effectively improving the efficiency and standardization of high-voltage busbar insulation tape winding.

[0004] However, the aforementioned winding equipment is only suitable for winding ordinary insulating tape with single-sided adhesive and no release film. To further improve the bonding strength, sealing performance, and insulation protection effect of high-voltage busbar insulating tape, existing maintenance operations are gradually adopting double-sided adhesive insulating tape. During the production process of this type of double-sided adhesive insulating tape roll, a release film needs to be attached to one side of the tape to prevent the tape layers from sticking together. When using the tape, the release film must be peeled off before the winding and pasting operation can be carried out.

[0005] When the above-mentioned insulating wrapping machine is used with double-sided adhesive tape with release film, the release film peeled off during the tape release process cannot be effectively collected and recycled. The disorderly scattering of the release film interferes with the continuous winding operation of the equipment, making it impossible to achieve automated and continuous winding construction of double-sided adhesive tape. The poor equipment adaptability greatly limits the promotion and application of new high-performance double-sided insulating tape in high-voltage busbar insulation reinforcement operations. Summary of the Invention

[0006] The purpose of this invention is to provide a high-voltage busbar insulation winding device with release film recycling function, so as to solve the problems of existing high-voltage busbar insulation winding devices that cannot recycle the release film of the tape and cannot be adapted to double-adhesive surface insulation tape operations.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage busbar insulation winding device with release film recycling function, comprising a support with a C-shaped opening, a mounting plate capable of revolving around the C-shaped opening, a tape unwinding mechanism disposed on the mounting plate, and a tape head positioning and cutting mechanism disposed on the support; further comprising: a release film winding mechanism, disposed on the mounting plate for winding the release film separated from the tape, comprising a spring device mounted on the mounting plate and a winding wheel disposed on the spring shaft of the spring device; the winding wheel is formed by the mating of a main wheel part and a secondary wheel part of equal diameter, for winding the release film separated from the tape, the main wheel part is unidirectionally rotatably connected to the spring shaft, the secondary wheel part is radially elastically slidably connected to the main wheel part to create a clamping gap between the two parts, and a locking component is provided between the main wheel part and the secondary wheel part for locking the two in the mating state.

[0008] Furthermore, the tape unwinding mechanism includes a tape shaft fixedly connected to the mounting plate, a split expansion sleeve for mounting the tape roll is coaxially fixedly connected to the tape shaft, and a tapered expansion core is threadedly connected to the end of the tape shaft.

[0009] Furthermore, the locking assembly includes a first arc portion coaxially fixedly connected to one end of the main wheel portion, a second arc portion coaxially fixedly connected to one end of the auxiliary wheel portion and having the same diameter as the first arc portion, a third arc portion coaxially fixedly connected to one end of the second arc portion via a tapered portion and having a diameter smaller than the diameter of the second arc portion, and a slip ring coaxially slidably sleeved on the first arc portion; one of the slip ring and the mainspring barrel of the mainspring device has a plurality of lock holes arranged in a circumferential array, and the other is fixedly connected to a locking rod that can be inserted and engaged with any of the lock holes.

[0010] Furthermore, a groove is provided on the planar side of the first arc portion, and a slide rod is fixedly connected to the planar side of the second arc portion and slidably connected to the groove. An elastic unit is provided between the groove and the slide rod. The process of the elastic unit restoring its deformation drives the slide rod to slide out of the groove, thereby creating a clamping gap between the auxiliary wheel portion and the main wheel portion.

[0011] Furthermore, a ratchet is coaxially fixedly connected to one of the mainspring shaft and the main wheel, and a pawl that cooperates with the ratchet is elastically rotatably connected to the other.

[0012] Furthermore, the mounting plate is provided with a guide wheel assembly for guiding the adhesive tape, the guide wheel assembly including two guide wheels and a reduction wheel located between the two guide wheels.

[0013] Furthermore, a winding knob is fixedly connected to one end of the mainspring shaft.

[0014] Furthermore, an arc-shaped rack is slidably connected to the support, and an elastic element is provided between the arc-shaped rack and the support. The process of the elastic element restoring its deformation drives the arc-shaped rack to slide on the support to the target position. When the upper gear, which is connected to the spring shaft, revolves with the mounting plate, it can mesh with the arc-shaped rack.

[0015] Furthermore, a first ear plate with a through hole is fixedly connected to the support, and a second ear plate with a screw hole is fixedly connected to the arc-shaped rack. An adjusting bolt passes through the through hole and is threadedly connected to the screw hole.

[0016] Furthermore, the elastic element includes a second compression spring movably sleeved on the adjusting bolt, with one end of the second compression spring abutting against the first ear plate and the other end abutting against the second ear plate.

[0017] Compared with existing technologies, the present invention provides a high-voltage busbar insulation winding device with release film recycling function. Addressing the technical shortcomings of traditional insulation winding devices that cannot adapt to double-sided adhesive tape with release film and that the release film cannot be recycled, this invention adds a release film winding mechanism. Utilizing the automatic tightening characteristics of the spring device, it continuously provides rotational driving force to the winding wheel while the tape is being unwound and wound, automatically winding the release film. This enables continuous and automated winding of double-sided high-performance insulating tape, effectively improving the efficiency of busbar insulation reinforcement operations. It fully leverages the advantages of double-sided adhesive tape—strong adhesion and excellent sealing and insulation performance—significantly improving the insulation protection quality at defect locations on high-voltage busbars. This facilitates the large-scale application of the new double-sided insulating tape in the operation and maintenance of high-voltage equipment in substations.

[0018] The take-up reel adopts a main reel and a secondary reel structure. The secondary reel can slide radially and spring open relative to the main reel to form a clamping gap, which facilitates the quick insertion of the release film head after peeling. The locking component between the main reel and the secondary reel locks them in the mating state, so that the release film head is fixed on the take-up reel, thereby realizing the quick clamping of the release film head on the take-up reel.

[0019] The main wheel of the take-up wheel is unidirectionally connected to the mainspring shaft via a ratchet and pawl structure. This allows the mainspring shaft to rotate forward when the spring releases its force, causing the take-up wheel to rotate and wind up the release film. When the mainspring shaft is actively reversed to wind up the spring, the mainspring shaft can rotate relative to the main wheel without causing the take-up wheel to rotate in the same direction. Therefore, the release film wound on the take-up wheel will not be released. This achieves the function of winding the mainspring device midway when the release film has already been wound on the take-up wheel and there is no need to remove the wound release film.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-17 The present invention provides a high-voltage busbar insulation winding device with release film recycling function, which has release film recycling function and can be adapted to double adhesive surface insulation tape winding operation. It includes a support 1, a C-shaped toothed ring 3, a mounting plate 2, a drive mechanism 4, a tape unwinding mechanism 6, a guide wheel group 7, a tape head positioning and cutting mechanism 5, and a release film winding mechanism 8.

[0025] The support 1 has a C-shaped opening. The mounting plate 2 is fixedly connected to the C-shaped gear ring 3. The tape unwinding mechanism 6, the guide wheel assembly 7, and the release film winding mechanism 8 are all mounted on the mounting plate 2. Multiple limiting wheels arranged along the C-shaped opening are rotatably mounted on the support 1. The C-shaped gear ring 3 can rotate around the C-shaped opening under the limiting of each limiting wheel. The drive mechanism 4 provides driving force for the C-shaped gear ring 3, the mounting plate 2, and all components on the mounting plate 2 to revolve together along the C-shaped opening. The drive mechanism 4 includes a drive motor fixedly mounted on the support 1 and at least two spaced drive gears rotatably mounted on the support 1. The drive motor simultaneously drives the two drive gears to rotate via a belt assembly. At any given time, at least one drive gear remains engaged with the C-shaped gear ring 3, thereby ensuring that the C-shaped gear ring 3 always has rotational power.

[0026] The tape head positioning and cutting mechanism 5 is mounted on the support 1 and is used to position and fix the tape head at the beginning of the winding operation and to cut the tape head at the end of the winding operation. The tape head positioning and cutting mechanism 5 adopts existing technology and will not be described in detail here.

[0027] The tape unwinding mechanism 6 includes a tape shaft 61, a segmented expansion sleeve 62, and a conical expansion core 63. One end of the tape shaft 61 is fixedly connected to the mounting plate 2, and the other end has an external thread. The segmented expansion sleeve 62 is cylindrical, with one end being a round sleeve and the other end divided into multiple arc-shaped segments by multiple through grooves distributed along the generatrix and penetrating the inner and outer walls. The segmented expansion sleeve 62 is coaxially fixedly sleeved onto the tape shaft 61 by the round sleeve. The threaded section of the tape shaft 61 extends into the annular cavity formed by each arc-shaped segment, and there is a gap between the peripheral side of the tape shaft 61 and the outer wall of the annular inner ring (i.e., the inner wall of each arc-shaped segment) to accommodate the conical expansion core 63. One end of the conical expansion core 63 has a threaded groove along the axial direction, and its peripheral side has a tapered surface with a gradually changing diameter. The end of the conical expansion core 63 with the threaded groove extends into the annular cavity and is threadedly connected to the threaded section of the tape shaft 61.

[0028] After the double-sided adhesive insulating tape roll is placed on the segmented expansion sleeve 62, the conical expansion core 63 is screwed on to move it deeper into the annular inner cavity. The conical expansion core 63 squeezes each arc-shaped segment of the segmented expansion sleeve 62, which in turn expands each arc-shaped segment outward radially. Thus, each arc-shaped segment abuts against the inner ring wall of the double-sided adhesive insulating tape roll, thereby achieving the purpose of adjusting the rotational damping of the double-sided adhesive insulating tape roll on the segmented expansion sleeve 62 and achieving complete locking.

[0029] The guide wheel assembly 7 includes two guide wheels 71 and a reduction wheel 72. The reduction wheel 72 and the two guide wheels 71 are rotatably connected to the mounting plate 2. The reduction wheel 72 has a Teflon anti-stick coating on its surface and is located between the two guide wheels 71. The double-sided adhesive tape unwound by the tape unwinding mechanism 6 passes sequentially around one of the guide wheels 71, the reduction wheel 72, and the other guide wheel 71 without the release film being peeled off. The release film separates from the double-sided adhesive tape, and the release film head is fixed to the take-up wheel 82. The double-sided adhesive tape head with the release film peeled off is fixed to the tape head positioning and cutting mechanism 5.

[0030] As the double-sided adhesive tape with the release film still attached comes into contact with the deceleration wheel 72, the adhesive side facing away from the release film comes into contact with the deceleration wheel 72. There will be a certain degree of adhesion between the two, which helps to wrap the double-sided adhesive tape onto the busbar in a taut state and improve the insulation wrapping effect.

[0031] The release film winding mechanism 8 is used to wind up the release film separated from the double-adhesive insulating tape, and includes a spring device 81, a winding wheel 82, a ratchet 83, a pawl 84, and a locking assembly.

[0032] The mainspring device 81 includes a mainspring barrel 811, a mainspring spring 812 wound inside the mainspring barrel 811, and a mainspring shaft 813 rotatably connected to the center of the mainspring barrel 811. The mainspring barrel 811 is fixedly mounted on the mounting plate 2. The outer end of the mainspring spring 812 is connected to the inner wall of the mainspring barrel 811, and the inner end is connected to the mainspring shaft 813.

[0033] The take-up roller 82 is formed by the mating of a main roller portion 821 and a secondary roller portion 822 of equal diameter. The secondary roller portion 822 and the main roller portion 821 are elastically slidably connected and fitted. When no external force is applied, the secondary roller portion 822 is in a state of being spring-opened from the main roller portion 821, and a clamping gap is generated between the secondary roller portion 822 and the main roller portion 821, so that the release film head after peeling can be quickly embedded into the clamping gap. The main wheel 821 is rotatably connected to the mainspring shaft 813 (without axial displacement). A ratchet 83 and pawl 84 structure is provided between the main wheel 821 and the mainspring shaft 813, allowing only unidirectional rotation between them. The ratchet 83 and pawl 84 structure includes a ratchet 83 and a pawl 84. The ratchet 83 is coaxially and fixedly connected to the mainspring shaft 813, and the pawl 84 is elastically and rotatably connected to the main wheel 821 and engages with the ratchet 83; or, the ratchet 83 is coaxially and fixedly connected to the main wheel 821, and the pawl 84 is elastically and rotatably connected to the mainspring shaft 813 and engages with the ratchet 83. A locking assembly is also provided between the main wheel 821 and the auxiliary wheel 822. The locking assembly is assembled to lock the main wheel 821 and the auxiliary wheel 822 in an engaged state, thereby clamping and fixing the release film head to the take-up wheel 82.

[0034] When the spring spring 812 releases its elastic force, causing the spring shaft 813 to rotate clockwise, the spring shaft 813 engages with the ratchet 83 and pawl 84 structure, driving the main wheel 821 to rotate together and wind the release film. When the spring shaft 813 reverses to wind the spring spring 812 and store energy, the spring shaft 813 decouples from the ratchet 83 and pawl 84 structure and rotates freely, preventing the release film wound on the take-up wheel 82 from being released. However, when the spring shaft 813 actively reverses to wind the spring spring 812 and store energy, the spring shaft 813 decouples from the main wheel 821 through the ratchet 83 and pawl 84 structure, preventing the take-up wheel 82 from reversing. Therefore, the release film wound on the take-up wheel 82 will not be released, achieving the function of winding the spring mechanism 81 midway when the take-up wheel 82 already has release film wound on it and there is no need to remove the wound release film.

[0035] The locking assembly specifically includes a first arc portion 851, a second arc portion 852, a conical portion 853, a third arc portion 854, and a slip ring 855. The first arc portion 851 is coaxially fixedly connected to one end of the main wheel portion 821. The second arc portion 852 is coaxially fixedly connected to one end of the auxiliary wheel portion 822 and has the same diameter as the first arc portion 851. The third arc portion 854 is coaxially fixedly connected to the second arc portion 852, and the diameter of the third arc portion 854 is smaller than the diameter of the second arc portion 852. The two are connected by a transition through the conical portion 853. The slip ring 855 is coaxially slidably sleeved on the first arc portion 851. The slip ring 855 and the first arc portion 851 have a keyway structure, so that the slip ring 855 can only slide axially on the first arc portion 851 and cannot rotate circumferentially. The slip ring 855 has multiple locking holes 856 arranged in a circular array, and the mainspring barrel 811 of the mainspring device 81 is fixedly connected to a locking rod 857 that can be inserted and engaged with any of the locking holes 856; or, the mainspring barrel 811 has multiple locking holes 856 arranged in a circular array, and the slip ring 855 is fixedly connected to a locking rod 857 that can be inserted and engaged with any of the locking holes 856.

[0036] A groove 823 is formed on the flat side of the first arc portion 851, and a slide rod 824 that is slidably connected to the groove 823 is fixedly connected to the flat side of the second arc portion 852. An elastic unit 825 is provided between the groove 823 and the slide rod 824, thereby realizing the elastic sliding fit between the secondary wheel portion 822 and the main wheel portion 821. The process of the elastic unit 825 restoring its deformation drives the slide rod 824 to slide outward from the groove 823, thereby creating a clamping gap between the secondary wheel portion 822 and the main wheel portion 821. The elastic unit 825 is preferably a first compression spring, which is provided inside the groove 823, with one end abutting against the end of the slide rod 824 and the other end abutting against the bottom of the groove 823.

[0037] When the slip ring 855 is in the position abutting against the mainspring barrel 811, the slip ring 855 and the mainspring barrel 811 are temporarily positioned by a magnetic attraction structure 858 or a snap ring structure. The inner wall of the slip ring 855 corresponds to the small-diameter third arc portion 854, and the elastic force stored in the elastic unit 825 is released, creating a clamping gap between the auxiliary wheel portion 822 and the main wheel portion 821. (See reference...) Figures 6-8The double-sided adhesive tape roll on the tape unwinding mechanism 6 is first released in section, and then locked onto the split expansion sleeve 62 by twisting the conical expansion core 63. After the released double-sided adhesive tape passes over the guide wheel assembly 7, the double-sided adhesive tape head with the release film peeled off is fixed to the tape head positioning and cutting mechanism 5. The peeled release film head is then embedded in the clamping gap. Then, the slip ring 855 is pulled away from the spring box 811, and the slip ring 855 squeezes the conical part 8. 53. The auxiliary roller 822 slides towards the main roller 821 until the slip ring 855 slides to the end face of the take-up roller 82. The slip ring 855 and the take-up roller 82 are temporarily positioned by another magnetic attraction structure 858 or a snap ring structure. The inner wall of the slip ring 855 corresponds to the second arc portion 852. The slip ring 855 fits the second arc portion 852 with the first arc portion 851, thereby aligning the auxiliary roller 822 with the main roller 821, completing the clamping and fixing of the release film head. See reference. Figures 9-11 Then, slowly reverse the conical expansion core 63 until the resistance of the split expansion sleeve 62 to the inner ring wall of the double adhesive surface insulating tape roll is slightly greater than the force of the spring spring 812 driving the spring shaft 813 and the winding wheel 82 to rotate. At this time, the preparation work of the present invention is ready and the winding operation can be carried out.

[0038] In the above technical solution, there are two ways to wind and store energy in the spring device 81: The first way is that after the release film head is clamped and fixed, the spring spring 812 is energized by reversing the winding knob 814 fixedly connected to the end of the spring shaft 813. After the spring spring 812 is energized, it immediately generates a force that drives the spring shaft 813 and the winding wheel 82 to rotate forward and wind the release film, thereby tightening the release film. The second way is to reverse the spring shaft 813 in advance to store energy in the spring spring 812 before the release film head is clamped. However, after the spring spring 812 is energized, the spring shaft 813 needs to be locked to prevent the elastic potential energy of the spring spring 812 from being released. In this way, the present invention can be put into operation immediately after the release film head is clamped.

[0039] like Figures 6-11As shown, the second method described above is possible because when the auxiliary wheel 822 and the main wheel 821 are in a spring-open state, that is, when the locking assembly is not engaged and locked between the auxiliary wheel 822 and the main wheel 821, the slip ring 855 and the mainspring box 811 are circumferentially locked by the locking rod 857 and the locking hole 856. Since the slip ring 855 and the mainspring shaft 813 cannot rotate relative to each other in the circumferential direction, the mainspring shaft 813 and the mainspring box 811 are ultimately circumferentially locked, and the energy-storing mainspring spring 812 cannot drive the mainspring shaft 813 to rotate. After the release film head is inserted into the clamping gap between the auxiliary wheel 822 and the main wheel 821, the slip ring 855 slides away from the mainspring box 811 to lock the auxiliary wheel 822 and the main wheel 821 into a locked state to achieve the clamping and fixing of the release film head. At the same time, the locking rod 857 and the locking hole 856 are also separated, and the circumferential lock between the mainspring box 811 and the mainspring shaft 813 is released. The mainspring spring 812 can then generate a force to drive the mainspring shaft 813 and the winding wheel 82 to rotate forward and wind up the release film.

[0040] The specific structure and assembly method of the locking assembly achieves multiple functions: when the locking of the auxiliary wheel 822 and the main wheel 821 is released so that the release film head can be inserted into the clamping gap, the mainspring box 811 and the mainspring shaft 813 can be circumferentially locked to maintain the energy of the mainspring spring 812; when the auxiliary wheel 822 and the main wheel 821 are locked into the engaged state so that the release film head is clamped and fixed, the circumferential locking between the mainspring box 811 and the mainspring shaft 813 can be released so that the mainspring spring 812 can release its elastic force to drive the winding wheel 82 to wind up the release film.

[0041] Considering that the mainspring 812 has limited energy storage, in operations with a large number of winding turns, after the elastic potential energy of the mainspring 812 is released, it can no longer drive the winding wheel 82 to wind up the release film, and it is necessary to pause the winding operation and rotate the mainspring shaft 813 to replenish the energy of the mainspring 812 midway. The present invention provides the following preferred technical solution, which can automatically replenish the energy of the mainspring 812 during the winding operation.

[0042] Specifically, an arc-shaped rack 862 is slidably connected to the support 1 via a sliding structure 863. The sliding structure 863 employs a sliding block and a sliding track mechanism, with the sliding block mounted on the arc-shaped rack 862 and the sliding track on the support 1. During its sliding stroke on the support 1, the arc-shaped rack 862 has a target position coaxial with the C-shaped gear ring 3. At this target position, the arc-shaped rack 862 can mesh with the upper gear 861, which revolves with the mounting plate 2. This upper gear 861 is connected to the spring shaft 813. An elastic element 864 is provided between the arc-shaped rack 862 and the support 1. The process of the elastic element 864 restoring its deformation drives the arc-shaped rack 862 to slide to the target position on the support 1, such as... Figures 15-16As shown. A first ear plate 865 with a through hole is fixedly connected to the support 1. The first ear plate 865 is located on the outer side of the arc-shaped rack 862. A second ear plate 866 with a screw hole is fixedly connected to the middle of the arc-shaped rack 862. An adjusting bolt 867 passes through the through hole and is threadedly connected to the screw hole.

[0043] The elastic element 864 is preferably a second compression spring, which is movably sleeved on the adjusting bolt 867. One end of the second compression spring abuts against the first ear plate 865, and the other end abuts against the second ear plate 866. Depending on the direction of rotation of the drive mechanism 4 driving the mounting plate 2, the upper winding gear 861 is ensured to drive the mainspring shaft 813 to reverse and store energy in the mainspring spring 812 when the upper winding gear 861 meshes with the arc-shaped rack 862. There are two specific installation methods for the upper winding gear 861: one is that the upper winding gear 861 and the mainspring shaft 813 are directly coaxially fixedly connected; the other is that a reversing gear needs to be added between the upper winding gear 861 and the mainspring shaft 813, that is, the reversing gear is coaxially fixedly connected to the mainspring shaft 813, the upper winding gear 861 is rotatably connected to the mounting plate 2, and the upper winding gear 861 meshes with the reversing gear.

[0044] In the above technical solution, during the winding operation, the drive mechanism 4 drives the C-shaped gear ring 3, the mounting plate 2, and the various components on the mounting plate 2 to rotate. The elastic element 864 holds the arc-shaped rack 862 at the target position. When the spring device 81 passes through the range of the arc-shaped rack 862, the upper gear 861 meshes with the tooth group on the inner side of the arc-shaped rack 862, thereby driving the spring shaft 813 to reverse to store energy in the spring spring 812, thereby replenishing the energy consumed by the spring spring 812 in driving the take-up roller to take up the release film.

[0045] The sliding fit between the arc-shaped rack 862 and the support 1, as well as the setting of the elastic element 864, is a safety measure. The purpose is that if the spring 812 is wound to its maximum limit but the winding gear 861 is still within the range of the arc-shaped rack 862, the winding gear 861 will be unable to continue rotating, thus overcoming the elastic force of the elastic element 864 and pushing open the arc-shaped rack 862 (causing the arc-shaped rack 862 to disengage from the target position). A slippage phenomenon will occur between the winding gear 861 and the arc-shaped rack 862, thereby protecting the spring device 81.

[0046] When no intermediate power replenishment is required, the arc-shaped rack 862 can be actively positioned at a non-target position by turning the adjusting bolt 867, ensuring that the arc-shaped rack 862 never meshes with the upper gear 861. Figure 17 As shown.

[0047] The above technical solution also has the function of actively winding and storing energy for the unloaded spring device 81. In the preparation stage before the winding operation, before installing the double-sided adhesive insulating tape roll onto the tape unwinding mechanism 6, after the locking assembly circumferentially locks the spring box 811 and the spring shaft 813, the drive mechanism 4 drives the C-shaped gear ring 3, the mounting plate 2, and the various components on the mounting plate 2 to rotate several times, so that the spring device 81 passes through the area of ​​the arc-shaped rack 862 multiple times. Through the meshing of the winding gear 861 and the arc-shaped rack 862, the spring shaft 813 is driven to reverse, so that the spring spring 812 is fully charged. After the drive mechanism 4 stops, the subsequent preparatory work is completed, such as installing the double-sided adhesive insulating tape roll onto the tape unwinding mechanism 6, fixing the double-sided adhesive insulating tape after the release film is peeled off after passing around the guide wheel group 7 onto the tape head positioning and cutting mechanism 5, and clamping and fixing the release film head onto the tape head positioning and cutting mechanism 5.

[0048] It should be noted that the "forward rotation" and "reverse rotation" of the mainspring shaft 813 mentioned in this invention only indicate the relative rotation direction of the mainspring shaft 813, and do not correspond to the clockwise rotation direction.

[0049] The foregoing description of certain exemplary embodiments of the present invention should not be construed as limiting the scope of protection of the claims. Those skilled in the art will recognize that the described embodiments can be modified in other ways without departing from the spirit and scope of the invention.
