[0023] Please refer to Figure 1 , Figure 1 The present invention shows a three-dimensional structural schematic diagram of a cutting and gluing device, which includes: a first cutting mechanism 10, a second cutting mechanism 20, a separating mechanism 30 and a gluing mechanism 40. The first cutting mechanism 10 is used to divide a material strip 90 into a first part 91 and a second part 92. The separating mechanism 30 is used to separate the first part 91 and the second part 92 at a preset interval. The gluing mechanism 40 is used to attach tape to the first part 91 and the second part 92 to cover the opposite edges of the first part 91 and the second part 92. The second cutting mechanism 20 is used to cut the tape located at the interval to separate the first part 91 and the second part 92. Specifically, in the present embodiment, the cutting and gluing device includes four core mechanisms, namely a first cutting mechanism 10 for cutting the material tape 90 along an axial direction perpendicular to the material tape 90 to divide the material tape 90 into a first part 91 and a second part 92, a separating mechanism 30 for separating the first part 91 and the second part 92 from the cut surface, a gluing mechanism 40 for attaching the adhesive tape around the cut ends of the first part 91 and the second part 92, and a second cutting mechanism 20 for cutting the adhesive tape along an axial direction perpendicular to the material tape 90 to separate the first part 91 and the second part 92. At the end of the entire process flow, the material tape 90 with the adhesive tape around the cut end can be obtained. Since part of the adhesive tape is attached to the material tape 90 and the remaining part extends along the outer side of the cut end, the cut surface of the material tape 90 is protected. The present application is structurally interconnected. By using an extremely low-cost adhesive tape as a protective piece for the material tape 90, burrs on the cut end of the material tape 90 during the subsequent transfer process are avoided, thereby affecting the yield of the finished product, thereby effectively reducing the operating costs of the enterprise.

[0024] Optionally, the cutting and gluing device further comprises a conveying mechanism 50 and a frame 60, wherein the first cutting mechanism 10, the separation mechanism 30, the gluing mechanism 40 and the second cutting mechanism 20 are sequentially arranged in the first area of ​​the frame 60, the conveying mechanism 50 is arranged in the second area of ​​the frame 60, the conveying mechanism 50 is used to convey the material belt 90, and the first area is located above the second area. Specifically, in this embodiment, the cutting and gluing device further comprises a conveying mechanism 50 for conveying the material belt 90 and a frame 60 for fixing the first cutting mechanism 10, the separation mechanism 30, the gluing mechanism 40, the second cutting mechanism 20 and the conveying mechanism 50. In the illustrated structure, the frame 60 is a plate-like structure, wherein the first cutting mechanism 10, the separation mechanism 30, the gluing mechanism 40 and the second cutting mechanism 20 are sequentially arranged in the first area of ​​the frame 60, i.e., the top of the frame 60 in the length direction, and the conveying mechanism 50 is arranged in the second area of ​​the frame 60, i.e., the bottom of the frame 60 in the length direction. When the space for parking equipment changes due to the addition of other equipment in the production workshop, the user can move the cutting and gluing devices by moving the frame 60, effectively improving the space utilization. Figure 1 The material belt 90 is conveyed in the direction AA) and when the material belt 90 is located directly under the four mechanisms, the four mechanisms perform their respective functions, and each process proceeds step by step, thereby effectively improving production efficiency.

[0025] Optionally, the conveying mechanism 50 includes a conveyor belt 51 and a conveyor belt 51 driving unit. The conveyor belt 51 is recessed inwardly along the width direction to form a plurality of positioning grooves 511 for placing the material belt 90. The plurality of positioning grooves 511 are arranged at equal intervals along the length direction of the conveyor belt 51. The conveyor belt 51 driving unit is used to drive the conveyor belt 51 to move along the direction from the first cutting mechanism 10 to the second cutting mechanism 20. Specifically, in this embodiment, the conveying mechanism 50 includes a conveyor belt 51 for placing and conveying the material belt 90 and a conveyor belt 51 driving unit for driving the conveyor belt 51 to rotate. The length direction of the conveyor belt 51 is parallel to the direction from the first cutting mechanism 10 to the second cutting mechanism 20. The conveyor belt 51 is recessed inwardly along its width direction to form a plurality of positioning grooves 511 for fixing the material belt 90. Among them, the plurality of positioning grooves 511 are arranged at equal intervals along the length direction of the conveyor belt 51. Furthermore, the spacing between the positioning grooves 511 can correspond to the spacing between the first cutting mechanism 10, the separation mechanism 30, the gluing mechanism 40 and the second cutting mechanism 20, so that every time the conveyor belt 51 advances the same distance, the material belt 90 can proceed to the next process and finally exit from the discharge end.

[0026] Please refer to Figure 2, the positioning groove 511 is a V-shaped groove, and the groove width L of the positioning groove 511 is smaller than the diameter D of the material strip 90, and larger than the radius R of the material strip 90. Specifically, in the present embodiment, the positioning groove 511 is in the shape of a V-shaped groove, and its groove width L needs to be smaller than the diameter D of the material strip 90, and larger than the radius R of the material strip 90, so that the positioning groove 511 can effectively support the material strip 90 while also having a certain groove depth redundancy, so that the first cutting mechanism 10 and the second cutting mechanism 20 will not collide when cutting the material strip 90 downward.

[0027] Optionally, the first cutting mechanism 10 includes a first cutter 11, and the first cutter 11 is used to cut the material belt 90 along the circumference of the material belt 90 to obtain a first part 91 and a second part 92 of equal length. Specifically, in this embodiment, the first cutting mechanism 10 includes a first cutter 11 for cutting the material belt 90. When the conveyor belt 51 runs to the cutting station of the first cutter 11, the first cutter 11 moves downward and cuts the material belt 90 along the circumference of the material belt 90 to divide the material belt 90 into a first part 91 and a second part 92 of equal length. The driving motor for driving the first cutter 11 to move up and down can be set on the frame 60, which will not be described in detail here.

[0028] Optionally, the separation mechanism 30 includes a separation drive unit and a separation member 31, wherein the separation drive unit is used to drive the separation member 31 to switch between the intervention station and the separation station; when the separation member 31 is in the intervention station, the end of the separation member 31 is inserted between the first part 91 and the second part 92; when the separation member 31 is in the separation station, the separation member 31 is used to push the first part 91 and the second part 92 in opposite directions according to the spacing. Specifically, in this embodiment, the separation mechanism 30 includes a separation member 31 for separating the first part 91 and the second part 92 and a separation drive unit for driving the separation member 31 to work. The separator 31 has an intervention station and a separation station. When the separator 31 is located at the intervention station, the separation driving unit drives the separator 31 to move downward and insert its end into the gap between the first part 91 and the second part 92. Then, the separation driving unit drives the separator 31 to be located at the separation station. The separator 31 can push the first part 91 and the second part 92 in opposite directions according to the spacing set by the user. Due to the support of the positioning groove 511, the first part 91 and the second part 92 are only separated in the length direction by a distance for the subsequent gluing mechanism 40 to perform gluing. It can be understood that the spacing between the first part 91 and the second part 92 is less than the width of the tape.

[0029] Optionally, the separator 31 includes a first abutting top portion 311 and a second abutting top portion 312, wherein the first abutting top portion 311 is used to abut the first portion 91, and the second abutting top portion 312 is used to abut the second portion 92. When the first abutting top portion 311 and the second abutting top portion 312 are relatively closed, the separator 31 is in the intervention position; when the first abutting top portion 311 and the second abutting top portion 312 are relatively open, the separator 31 is in the separation position. Specifically, in one embodiment, the first abutting top portion 311 and the second abutting top portion 312 are of a scraper-type structure at the end close to the material strip 90, which can quickly, conveniently and accurately enable the separator 31 as a whole to reach the gap between the first portion 91 and the second portion 92. Further, the first abutting top portion 311 and the second abutting top portion 312 can be relatively closed and opened. When the first abutting top portion 311 and the second abutting top portion 312 are relatively closed, the first abutting top portion 311 and the second abutting top portion 312 are arranged back to back, and the two blade-shaped ends are directed outward, and the end of the first abutting top portion 311 abuts the first portion 91, and the end of the second abutting top portion 312 abuts the second portion 92. At this time, the separator 31 is in the intervention position. When the first abutting top portion 311 and the second abutting top portion 312 are relatively opened, the first abutting top portion 311 pushes the first portion 91 along the axial direction of the material strip 90, and the second abutting top portion 312 pushes the second portion 92 in the opposite direction to the first abutting top portion 311. At this time, the separator 31 is in the separation position.

[0030] Optionally, the glue sticking mechanism 40 includes a suction unit 41 and a glue sticking unit 42, wherein the suction unit 41 is used to suck the first part 91 and the second part 92 from the positioning groove 511, and the glue sticking unit 42 is used to stick the adhesive tape on the first part 91 and the second part 92 to cover the opposite edges of the first part 91 and the second part 92. Specifically, in this embodiment, the glue sticking mechanism 40 includes the suction unit 41 for sucking the first part 91 and the second part 92 from the positioning groove 511 into the air, and the glue sticking unit 42 for wrapping the adhesive tape around the first part 91 and the second part 92 along the opposite edges of the first part 91 and the second part 92 in the air and sticking it on the first part 91 and the second part 92. In one embodiment, the suction unit 41 is a suction cup structure, which can suck the sides of the first part 91 and the second part 92 and lift them into the air in a sucked state through a driving structure such as a driving motor or a cylinder. The user can set the length of each glue discharge of the glue sticking unit 42 to a fixed length to improve convenience. When the first part 91 and the second part 92 are sucked, the glue sticking unit 42 moves downward to stick the cut tape along the opposite edges of the first part 91 and the second part 92, so that the first part 91 and the second part 92 are connected together again. After the tape is pasted, the glue sticking unit 42 is reset, and the suction unit 41 puts the first part 91 and the second part 92 back on the positioning slot 511 to promote the development of the next process.

[0031] Optionally, the gluing unit 42 further includes a centering module, which is used to detect the length between the first part 91 and the second part 92, and to attach the tape to the first part 91 and the second part 92 in the center. Specifically, the gluing unit 42 further includes a centering module. It can be understood that since the width of the tape is a fixed value, in order to avoid the gluing unit 42 applying more tape to any part when applying the tape, so that the amount of tape on the other part is insufficient, thereby causing the cut end of the latter part to be unable to obtain sufficient protection, affecting the yield of the finished product, in this embodiment, by setting a centering module for detecting the distance between the first part 91 and the second part 92 inside the gluing unit 42, the gluing unit 42 can always ensure that the tape can be attached to the first part 91 and the second part 92 in the center when performing the gluing action.

[0032] Optionally, the second cutting mechanism 20 includes a second cutter 21, and the second cutter 21 is used to cut the tape located at the interval in the middle to separate the first part 91 and the second part 92. Specifically, in order to avoid the second cutting mechanism 20 from cutting the tape unevenly, the tape after cutting is more attached to any part, so that the amount of tape on the other part is insufficient, which leads to the incision end of the latter part not being able to obtain sufficient protection, affecting the yield of the finished product. In this embodiment, the second cutting mechanism 20 includes a second cutter 21 for cutting the tape. When the conveyor belt 51 runs to the cutting station of the second cutter 21, the second cutter 21 moves downward and cuts the tape in the middle along the interval between the first part 91 and the second part 92, so as to obtain the first part 91 and the second part 92 with equal amounts of tape. Among them, the driving motor for driving the second cutter 21 to move up and down can be set on the frame 60, which is not described in detail here.

[0033] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
