[0041] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Combine the following Figure 1-Figure 2 The utility model describes a roll-changing and tape-splicing device.

[0043] Figure 1 It is a structural schematic diagram of a roll-changing and tape-splicing device provided in an embodiment of the utility model.

[0044] like Figure 1 As shown, a roll changing and tape splicing device provided by an embodiment of the utility model includes: a blue film roll changing component 1, an automatic tape splicing component 2, a separation component 3 and a release paper roll changing component 4; the blue film roll changing component 1, the automatic tape splicing component 2, the separation component 3 and the release paper roll changing component 4 are sequentially transmitted and connected to form an assembly line process; the blue film roll changing component 1 is used for switching the blue film with release paper, the automatic tape splicing component 2 is used for bonding the blue film with release paper after switching with the blue film with release paper before switching, the separation component 3 is used for separating the blue film with release paper into blue film and release paper, and the release paper roll changing component 4 is used for recycling release paper.

[0045] In a specific implementation process, the blue film combined with the release paper and the blue film is defined as the blue film with release paper, that is, two layers are pasted together, one layer is the blue film, and the other layer is the release paper. When the equipment issues an alarm prompt to remind that the blue film with release paper is out of material, the blue film with release paper needs to be replaced at this time. The roll-changing and splicing equipment in this embodiment automatically completes the replacement and splicing of the blue film with release paper. After the replacement and splicing are completed, the equipment operates normally. The whole process does not stop, or the pause time is very short, which effectively ensures the work efficiency of the equipment. The transmission connection of the blue film roll-changing component 1, the automatic splicing component 2, the separation component 3 and the release paper roll-changing component 4 refers to the order of the process between each component, and the blue film with release paper is transmitted to form an assembly line process. Splicing refers to the continuation of the blue film with release paper to ensure the continued transmission of the blue film with release paper.

[0046] Among them, the automatic reel changing and splicing of the blue film with release paper relies on the blue film reel changing component 1, the automatic splicing component 2, the separation component 3 and the release paper reel changing component 4. Each component cooperates with each other to form an assembly line process, that is, the work of the latter process component depends on the work result of the previous process component. The workflow is that the blue film reel changing component 1 replaces the blue film with release paper. When it does not need to be replaced, the blue film reel changing component 1 unwinds the blue film to the automatic splicing component 2, and the automatic splicing component 2 does not work. Then the blue film with release paper enters the separation component 3, and the blue film with release paper is separated by the separation component 3 to achieve the separation of the blue film and the release paper. The blue film is used normally, and the release paper is recycled through the release paper reel changing component 4. When the entire production line process reaches the point where the blue film with release paper in the blue film roll changing component 1 is unwound, a material shortage alarm is issued, and then the blue film roll changing structure completes the replacement of the new blue film roll with release paper. The replaced blue film roll is connected with the blue film roll on the production line before the replacement through the automatic tape connection component 2. After the tape connection is completed, the newly replaced blue film with release paper is connected with the blue film with release paper before the replacement, so that work and production can continue. The entire process is completed automatically without excessive manual participation, which can ensure the efficiency and quality of roll replacement, and also ensure the efficiency of production.

[0047] Figure 2 yes Figure 1 Schematic diagram of the structure of the automatic tape splicing components.

[0048] Furthermore, if Figure 1 and Figure 2As shown, on the basis of the above embodiment, the automatic tape splicing component 2 in this embodiment includes: a tape splicing and cutting platform 21, a cutting platform 22, and a gluing platform; the tape splicing and cutting platform 21, the cutting platform 22 and the gluing platform are all arranged on the module; the tape splicing and cutting platform 21 is used to fix the tape release paper blue film to be switched; the cutting platform 22 is used to cut the tape release paper blue film to be switched; the blue film roll changing component 1 is used to switch the new tape release paper blue film; the gluing platform is used to bond the new tape release paper blue film with the tape release paper blue film before switching.

[0049] Specifically, the automatic tape splicing component 2 is used to splice the new release paper blue film with the old release paper blue film, that is, to continue splicing the release paper blue film to ensure that the equipment can operate normally. When the release paper blue film is unwound, a material shortage reminder is received. At this time, the old roll of release paper blue film needs to be replaced after use, so the splicing and cutting platform 21 is controlled to translate to press the release paper blue film to be replaced for fixing. Then the cutting platform 22 is controlled to move and the old blue film with release paper is cut. After the cutting is completed, the cutting platform 22 is reset, and the tape splicing and cutting platform 21 is reset. Then the new blue film with release paper is rotated to the current tape splicing position through the blue film roll changing component 1. At this time, the new blue film with release paper and the old blue film with release paper are both in the tape splicing position. Then the gluing platform is controlled to move for gluing, and the new blue film with release paper is bonded to the old blue film with release paper to achieve the splicing of the blue film with release paper, and then the work can be continued, and the subsequent separation and release paper recycling are carried out normally. The new blue film with release paper refers to the unused blue film with release paper, and the old blue film with release paper refers to the used blue film with release paper. After the old blue film with release paper is used up, it is spliced ​​with the new blue film with release paper, so as to ensure the smooth splicing of the blue film with release paper, so as to continue the work.

[0050] When the glue sticking platform is glue sticking, the glue sticking platform can be controlled to upgrade in the vertical direction, and then the gap between the release paper and the blue film is bonded by using the adhesive tape.

[0051] Furthermore, if Figure 1 As shown, the gluing platform includes a first gluing mechanism 231 and a second gluing mechanism 232; the first gluing mechanism and the second gluing mechanism 232 are respectively arranged on opposite sides of the blue film with release paper; the first gluing mechanism is used to bond the new blue film with release paper to the first surface of the blue film with release paper before switching; the second gluing mechanism is used to bond the new blue film with release paper to the second surface of the blue film with release paper before switching. The opposite sides refer to the two sides of the blue film with release paper, so as to ensure that both sides can be glued and the firmness of the glue is ensured.

[0052] Specifically, the gluing mechanism is divided into two parts, and the two sides of the blue film with release paper are glued separately, which can ensure the bonding effect. Figure 1 As shown, the first gluing mechanism 231 is bonded to the first surface, i.e., the upper surface, and the second gluing mechanism 232 is bonded to the second surface, i.e., the lower surface. By bonding both surfaces, the detachment phenomenon due to weak bonding can be avoided.

[0053] Among them, the second gluing mechanism 232 is located in the downstream process of the first gluing mechanism 231; after the first gluing mechanism 231 adheres to the first surface, the second gluing mechanism adheres to the second surface. That is, after the cutting is completed and the continued release paper blue film is in place, the first gluing mechanism 231 is used to complete the gluing of the first surface. For example, the upper surface is glued first, and then the release paper blue film after gluing is transferred to the position of the second gluing mechanism 232, and the second gluing mechanism 232 is controlled to complete the gluing of the second surface (lower surface), thereby completing the gluing of the two surfaces in sequence. By sequentially gluing the two surfaces, the positions of the first gluing mechanism 231 and the second gluing mechanism 232 can be better optimized to avoid low space utilization at the same position.

[0054] The first gluing mechanism 231 and the second gluing mechanism 232 are both bonded by means of adhesive tapes, and the gluing operation can be completed by only controlling the lifting and lowering of the first gluing mechanism 231 and the second gluing mechanism 232 .

[0055] In order to simplify the structure of cutting and gluing, the first gluing mechanism 231 and the cutting platform 22 are both arranged on the main lifting mechanism, and the cutter 221 of the cutting platform 22 is arranged on the auxiliary lifting mechanism; the main lifting mechanism is used to control the lifting and lowering of the first gluing mechanism and the cutting platform 22; the auxiliary lifting mechanism is used to control the retraction or extension of the cutter 221. Among them, the tape cutting platform 21 includes a cutter groove 211; the cutter groove 211 matches the cutter 221.

[0056] Specifically, the first gluing mechanism 231 and the cutting platform 22 are arranged on the same main lifting mechanism, so that the first gluing mechanism and the cutting platform 22 can be upgraded and controlled by one lifting mechanism, and the setting of the lifting mechanism can also be reduced. In order to ensure that the cutter 221 does not affect the gluing when the main lifting mechanism controls the first gluing mechanism 231 to gluing, a secondary lifting mechanism is separately arranged for the cutter 221. The secondary lifting mechanism is mainly used to control the extension or retraction of the cutter 221. When cutting, the secondary lifting mechanism is controlled to extend the cutter 221, and when gluing, the secondary lifting mechanism is controlled to retract the cutter 221 to avoid affecting the gluing.

[0057] Further, based on the above embodiment, Figure 1As shown, the blue film reel changing component 1 in this embodiment includes: a first blue film reel changing mechanism 11 and a second blue film reel changing mechanism 12; the first blue film reel changing mechanism 11 and the second blue film reel changing mechanism 12 are arranged on a turntable 14 and are located on both sides of the axis of the turntable 14; the first blue film reel changing mechanism 11 and the second blue film reel changing mechanism 12 can both rotate to the tape splicing position of the automatic tape splicing component 2. And the first blue film reel changing mechanism 11 and the second blue film reel changing mechanism 12 both include: a reel changing shaft and a rubber roller 13; the reel changing shaft and the rubber roller 13 are both arranged on the turntable 14; the reel changing shaft is used to carry the blue film with release paper, and the rubber roller 13 is used to unwind the blue film with release paper to the tape splicing position.

[0058] Specifically, the first blue film reel changing mechanism 11 and the second blue film reel changing mechanism 12 are used as backup. When one of them is unrolled, the other is controlled to be replaced to continue the blue film with release paper, ensuring a very short downtime. The switching method is to rotate the turntable 14 180 degrees to achieve switching. After rotating 180 degrees, the switched blue film reel changing component 1 mechanism maintains the position of the blue film reel changing mechanism before switching, automatically achieving seamless connection. The reel changing shaft is mainly used to carry the blue film with release paper, and the rubber roller 13 is mainly used to unwind the blue film with release paper. Figure 1 The structure shown has a simple and efficient way to change the roll of release paper blue film, and can quickly complete the roll change. The roll change process can be performed manually or automatically, thereby ensuring both the effect and efficiency of roll change, and further ensuring the quality and efficiency of tape splicing.

[0059] Further, based on the above embodiment, Figure 1 As shown, the release paper reel changing component 4 in this embodiment includes: a release paper reel changing shaft 41 and a release paper pressing roller 42; the release paper reel changing shaft 41 is used to recycle the release paper after passing through the release paper pressing roller 42. The release paper reel changing shaft 41 includes: a first release paper reel changing shaft and a second release paper reel changing shaft; both the first release paper reel changing shaft and the second release paper reel changing shaft can recycle the release paper after passing through the release paper pressing roller.

[0060] Specifically, the release paper roll changing component 4 is mainly used to recycle the release paper after separation. The release paper is wound onto the release paper roll changing shaft through the release paper pressure roller. As the assembly line operation continues, when the release paper recycling reaches a certain thickness, it is replaced by another release paper roll changing shaft, which is the same as the blue film roll changing shaft. Therefore, the release paper can be recycled seamlessly through another release paper roll changing shaft, effectively ensuring the recycling efficiency of the release paper.

[0061] The utility model of the automatic roll-changing and tape-splicing equipment with release paper blue film can effectively reduce the downtime of the equipment by automatically changing rolls, splicing, separating and recycling release paper, and the automatic roll-changing and tape-splicing can also ensure the standardization and quality of the tape splicing. It can also efficiently complete the recycling of release paper. The entire process is not disturbed by manual work and downtime, which effectively improves the working efficiency and production efficiency of the equipment.

[0062] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0063] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
