[0036] The embodiment of the present application discloses a roll-changing pre-treatment device for performing adhesive removal and adhesive application treatments on a new material roll 107 .

[0037] See also Figure 1 , an embodiment of a roll change pretreatment device provided in the embodiments of the present application includes:

[0038] A mobile device 103, a free drive device 102 and at least one execution end 101, wherein the mobile device 103 can move between different working areas, the free drive device 102 is connected between the mobile device 103 and the execution end 101, and a glue sticking device 2 is provided on one side of the execution end 101.

[0039] The tape glue processing equipment designed in this application has the following beneficial effects:

[0040] 1. Independently set up a roll-changing pretreatment device with glue-applying function, and enable it to move between different working areas, so that it can go back and forth between different roll-changing devices to perform roll-changing pretreatment operations during the roll-changing process, achieving the effect of one machine with multiple uses.

[0041] 2. Setting up the roll-changing pretreatment equipment independently also avoids the operational limitations of directly integrating it into the roll-changing equipment, and enables more flexible and convenient glue-laminating operations.

[0042] The above is an embodiment of the present invention provided by the embodiment of a roll change pretreatment device. The following is an embodiment of the present invention provided by the embodiment of a roll change pretreatment device. For details, please refer to Figures 1 to 5 .

[0043] Based on the solution of the above embodiment 1:

[0044] Furthermore, if Figure 4 as well as Figure 5 As shown, the gluing device 2 is designed to have a gluing mechanism 23, which includes a gluing pressing wheel 231 and a pressing driving member 233 for driving the gluing pressing wheel 231. The central axis of the gluing pressing wheel 231 is arranged on a pressing wheel frame 232. The pressing driving member 233 can be a telescopic cylinder, and is connected to the pressing wheel frame 232, and is used to drive the gluing pressing wheel 231 to move, so as to press the glue of the new adhesive tape onto the free end of the material tape of the new material roll 107.

[0045] The applicant has discovered that in the prior art, when the adhesive is applied along the surface of the material roll, the surface of the material roll is not flat. When the adhesive tape is applied along the width direction of the material roll, since there is a curved surface at the same position with the characteristics of being high in the middle and low at both ends, if the adhesive tape is applied along the width direction of the material roll, the rolled tape assembly is lifted up by the raised material roll with the high center, and the width sides of the tape cannot be applied to the surface of the material roll. To solve the above problem, the adhesive application roller 231 of the present application has an extrusion deformation portion, which is arranged on the surface of the adhesive application roller. The extrusion deformation portion can be deformed during adhesive application and tightly attached to the surface of the material roll, thereby better attaching the adhesive to the new material roll 107 with a curved surface, solving the problem that the width sides of the tape cannot be applied to the surface of the material roll.

[0046] Furthermore, if Figure 1 As shown, the actuator end 101 and the driving end of the free drive device 102 are detachably connected via a connector 106. The connector 106 is a conventional quick-connect structure, which includes a first quick connector 104 and a second quick connector 105; the first quick connector 104 is installed at the driving end of the free drive device 102, and the second quick connector 105 is installed at the actuator end 101; in this way, the connection and disassembly of the actuator end 101 can be completed quickly, further improving efficiency.

[0047] Regarding the design of the free drive device 102 , it may be a multi-axis drive component, such as a multi-axis robot arm.

[0048] The roll-changing pretreatment equipment can also be designed to have a glue-removing function, that is, a glue-removing device 1 installed on the execution end 101 is added.

[0049] Furthermore, a glue removing device 1 may be provided on the first surface of the execution end 101 ; the glue removing device 1 is used for removing the glue from the initial adhesive tape of the free end of the fixed material tape on the new material roll 107 .

[0050] A gluing device 2 is disposed on the second surface of the execution end 101 ; the gluing device 2 is used to perform gluing processing on the free end of the material strip.

[0051] The above design integrates the adhesive peeling device 1 for peeling adhesive and the adhesive sticking device 2 for sticking adhesive on one execution end 101 .

[0052] Furthermore, there are at least two execution ends 101.

[0053] like Figure 4 as well as Figure 5 As shown, a glue removing device 1 is provided on one of the execution ends 101 .

[0054] like Figure 3 As shown, a glue sticking device 2 is provided on the other execution end 101 .

[0055] In the above design, the adhesive peeling device 1 for peeling adhesive and the adhesive sticking device 2 for sticking adhesive are respectively arranged on different execution ends 101 .

[0056] Furthermore, if Figure 3 As shown, for the design of the adhesive peeling device 1, it includes a clamping mechanism 11, and the clamping part of the clamping mechanism 11 is arranged on the execution end 101 through a clamping assembly, and is used to clamp the initial adhesive tape. The clamping mechanism 11 clamps the initial adhesive tape, and then under the drive of the free drive device 102, the action of tearing off the initial adhesive tape can be completed.

[0057] Furthermore, if Figure 3 As shown, the adhesive peeling device 1 further includes an adhesive peeling detection component 12, which is used to obtain the position information of the edge interface of the free end of the initial adhesive tape or the material tape. The adhesive peeling detection component 12 can be a color code detection component, which can identify areas with different colors. Therefore, when the adhesive peeling detection component 12 is used for edge detection, the position of the edge interface of the free end of the material tape, or the position of the edge where the initial adhesive tape and the material tape (foil) of the new material roll 107 are attached can be identified.

[0058] The initial adhesive tape is pasted on the new material roll 107 along the length direction of the material roll 107. Therefore, during the adhesive removal process, the initial adhesive tape is torn off along the length direction of the material roll 107.

[0059] Furthermore, if Figure 4 as well as Figure 5 As shown, the glue sticking device 2 further includes a glue sticking unwinding mechanism 21 , a glue sticking rewinding mechanism 22 and a glue sticking cutting mechanism 24 which are sequentially arranged on the surface of the execution end 101 .

[0060] The adhesive unwinding mechanism 21 is used to release the new adhesive tape; the adhesive rewinding mechanism 22 is arranged on one side of the adhesive unwinding mechanism 21, and is used to rewind the isolation layer on the new adhesive tape; the adhesive unwinding mechanism 21 and the adhesive rewinding mechanism 22 are respectively arranged at both ends.

[0061] The glue pressing mechanism 23 is arranged between the glue unwinding mechanism 21 and the glue rewinding mechanism 22, and is used for pressing the glue on the new adhesive tape onto the free end of the material tape.

[0062] The glue cutting mechanism 24 is arranged on the side of the glue pressing mechanism 23 close to the glue unwinding mechanism, and is used to cut the glue on the newly applied tape. The glue cutting mechanism 24 includes a cutter 241, a knife seat 242, and a cutting driver 243; the knife seat 242 is arranged on the execution end 101, the cutter 241 is arranged on one side of the knife seat 242, and a cutting gap is formed between the knife seat 242 to cut the glue; the cutting driver 243 can be a telescopic cylinder, which is connected to the cutter 241 and is used to drive the cutter 241 to move so as to cut the glue on the tape.

[0063] In the present application, the glue sticking device 2 is to stick glue (stick long glue or stick multiple short glues at intervals) along the width direction of the material strip of the new material roll 107. In order to accurately stick glue, the glue sticking device 2 also includes a glue sticking detection component 25, which is used to obtain the position information of the edge of the free end of the material strip. The glue peeling detection component 12 can be a color code detection component that can identify areas with different colors. Therefore, when the glue peeling detection component 12 is used for edge detection, the position of the edge of the free end of the material strip can be identified.

[0064] When gluing, plan the gluing route, stick the long glue along the width direction of the new material roll 107, determine the starting position of gluing, and the glue detection component 25 identifies the center of the glue width and starts gluing along the width direction of the material roll.

[0065] Furthermore, if Figure 4 as well as Figure 5 As shown, a flattening mechanism 4 is also provided on the execution end 101 .

[0066] The flattening mechanism 4 is used to perform secondary flattening on the colloid on the free end of the material strip by the glue sticking device 2 .

[0067] Or the flattening mechanism 4 is used to press the free end of the material strip onto the material strip below it.

[0068] The design of the flattening mechanism 4 includes a wheel body 41, a connecting seat 43 and an elastic member 44; the wheel body 41 is rotatably mounted on the wheel seat 42, and the wheel seat 42 is connected to the connecting seat 43 through the elastic member 44, and the elastic member 44 is used to provide a force for the wheel body 41 to press against the free end of the colloid or the material belt to achieve better pressing; a guide rod (not shown in the figure) is fixed on the wheel seat 42, and the guide rod movably passes through the connecting seat 43 and is provided with a limit member at one end passing through the connecting seat 43263; the elastic member 44 can be a compression elastic member 44, which is sleeved on the guide rod.

[0069] Furthermore, if Figure 2 as well as Figure 3As shown, after the initial tape at the free end of the material strip is peeled off, the free end of the material strip will be in a floating state, which will increase the difficulty of subsequent gluing processing and affect the gluing accuracy. To solve this problem, a spray device 3 is also provided on the execution end 101; the spray device 3 is used to spray liquid substances on the free end of the material strip and the gap between the material strips located below the free end of the material strip.

[0070] In order to better spray the liquid substance, the roller shaft of the pressing roller device 108 in the roll changing device can be designed as a vacuum adsorption roller, which is connected to a vacuum device; the pressing roller device 108 is configured to adsorb the free end of the material strip and form a certain gap space 109 between the free end of the material strip and the material strip below it. The pressing roller device 108 is also used to press the free end of the material strip and the material strip below it together after the liquid substance is sprayed in the gap space 109.

[0071] The spraying device 3 can specifically be a sprayer. After spraying water mist at the gap space 109, the negative pressure adsorption function of the roller is turned off, and the free end of the material strip is pressed back onto the new material roll 107. Under the action of the liquid substance, the originally floating free end of the material strip can be well attached to the new material roll 107, and a small amount of liquid substance will not affect the subsequent tape splicing operation; after the free end of the material strip is attached to the new material roll 107, the subsequent gluing process can be carried out accurately; the liquid substance in this application is a volatile liquid that will not damage the material strip, such as tap water, purified water, etc., and there is no specific limitation.

[0072] The spray device 3 in the present application can be arranged on the same execution end 101 as the adhesive removal device 1, without any specific limitation.

[0073] The above is a detailed introduction to a roll changing pretreatment device provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
