Detailed Embodiment

[0021] The following will be combined with Figures 1-4 to further elaborate on the present invention in detail.

[0022] The embodiment of the present invention discloses a high-precision die-cutting and laminating device. Refer to Figure 1 and Figure 2, The high-precision die-cutting and laminating device includes a machine body 1, a sliding body 2, a guide wheel 3, a flattening mechanism and a driving member; among them, there are two sliding bodies 2, and the two sliding bodies 2 are relatively slidably arranged on the machine body 1. The sliding direction of the sliding body 2 is perpendicular to the conveying direction of the material tape. The two sliding bodies 2 are located on the opposite sides of the material tape. Specifically, in order to facilitate the guiding of the sliding of the sliding body 2, two vertical plates 12 are respectively fixed on both sides of the material tape on the machine body 1. Guide rails 13 are fixedly installed on both vertical plates 12. The guide rails 13 correspond to the sliding bodies 2 one by one. The length direction of the guide rails 13 is parallel to the moving direction of the sliding body 2. The sliding body 2 is slidably sleeved on the corresponding guide rail 13; the sliding body 2 can be any one of a plate shape, a strip shape, and a block shape, and is not limited here. The driving member is arranged on the vertical plate 12, and the driving member is used to drive the sliding body 2 to move.

[0023] Referring to Figure 2 , A fixing column 4 is fixedly installed on each sliding body 2. The fixing column 4 is arranged in the vertical direction. The guide wheels 3 correspond to the sliding bodies 2 one by one. The guide wheels 3 are rotatably sleeved on the fixing columns 4 of the corresponding sliding bodies 2 through bearings. The rotation axis of the guide wheels 3 is arranged in the vertical direction. The guide wheels 3 are used to abut against the edge of the flexible material tape; the flattening mechanism is used to keep the flexible material tape at the guide wheel 3 flat.

[0024] During the conveying process of the flexible material tape, the edge of the material tape slides against the guide wheel 3. Since the guide wheel 3 can rotate, the friction force on the edge of the flexible material tape is small, and the material tape is not easily worn; when it is necessary to adjust the position of the material tape for positioning correction, start the driving member, and drive the two sliding bodies 2 to move synchronously in the required direction through the driving member. Then, when the guide wheel 3 on the sliding body 2 drives the flexible material tape to move, at this time, the flattening mechanism is used to keep the flexible material tape at the guide wheel 3 flat, so that the edge of the flexible material tape is not easily wrinkled, the precision of die-cutting and laminating is improved, and the die-cutting and laminating quality is guaranteed to a certain extent.

[0025] Specifically, the guide wheel 3 in the present invention can be installed at the position before the material tape is laminated, or can be installed at the position before die-cutting after lamination. The installation position can be set by the operator according to needs.

[0026] Referring to Figure 2 , To facilitate driving the sliding body 2 to move, the driving member includes a cylinder 11. The cylinders 11 correspond to the sliding bodies 2 one by one. The cylinders 11 are fixedly installed on the corresponding vertical plates 12. The extending direction of the cylinders 11 is parallel to the sliding direction of the sliding body 2. The sliding body 2 is fixedly connected to the piston rod of the corresponding cylinder 11. Both cylinders 11 are electrically connected to the controller on the machine body 1. In other embodiments, the cylinder 11 can be replaced by an electric cylinder, an electric push rod, etc.

[0027] When it is detected that the material strip is deflected, the controller on the body 1 drives the two cylinders 11 to start, and the two cylinders 11 synchronously drive the corresponding sliding bodies 2 to move in the direction away from the deflection of the material strip, so that the material strip can be driven to move through the guide wheel 3 to correct the position of the material strip; using a controller for unified control helps to achieve synchronization of the two sliding bodies 2 and improve the accuracy of die-cutting and laminating.

[0028] Reference Figure 2 and Figure 3 In order to facilitate the limiting of the material strip, the guide wheel 3 includes a guide column 31 and a fixed plate 32. The guide column 31 is rotatably sleeved on the corresponding fixed column 4 in the vertical direction through a bearing. There are two fixed plates 32, and the two fixed plates 32 are relatively fixed at both ends of the guide column 31. The fixed plates 32 are also rotatably sleeved on the corresponding fixed columns 4, so that the longitudinal section of the guide wheel 3 is I-shaped. The outer wall of the guide column 31 is used to abut the edge of the flexible material strip. The two fixed plates 32 are located on the upper and lower sides of the flexible material strip, thereby providing sufficient space for the passage of the material strip and adapting to the passage of material strips of different thicknesses.

[0029] Reference Figure 2 and Figure 3 The outer wall of the guide post 31 is covered with an elastic layer (not shown). This elastic layer is used to abut against the edge of the flexible strip. Specifically, the elastic layer can be a polyurethane layer, a rubber layer, or the like, without limitation. Direct contact between the elastic layer and the edge of the flexible strip reduces frictional damage to the strip due to its low hardness, thus preventing wrinkles at the edge of the strip.

[0030] Reference Figure 2 and Figure 3 To facilitate the flattening of the flexible material strip at the guide wheel 3, the flattening mechanism includes a gas input pipe 5 and a delivery channel 6. The gas input pipe 5 is fixedly installed at the upper end of the fixed column 4 and is used to communicate with an external air source. Specifically, the gas input pipe 5 can be connected to an external blower to input airflow. The delivery channel 6 is arranged in the fixed column 4 and is connected to the gas input pipe 5. Each fixed plate 32 has a cavity 7, which is opened along the circumference of the fixed column 4 and passes through the inner wall of the fixed plate 32. The cavity 7 is connected to the delivery channel 6, so that gas can enter the cavity 7 through the gas input pipe 5 and the delivery channel 6. The fixed plate 32 has a plurality of air outlet holes 8 on the side close to the flexible material strip, and the air outlet holes 8 are connected to the corresponding cavities 7. Specifically, the plurality of air outlet holes 8 are arranged in multiple circles along the circumference of the fixed plate 32. The air outlet holes 8 on the upper and lower fixed plates 32 are aligned one by one. The diameter of the air outlet holes 8 is less than 1 mm, which helps to uniformly apply wind pressure to the surface of the flexible material strip.

[0031] When the sliding body 2 moves, an external blower is started to convey the air source to the gas input pipe 5. The air source enters the conveying channel 6 through the gas input pipe 5, and then enters the cavities 7 corresponding to the two fixing plates 32 respectively. Then the air flow jets out from the plurality of air outlet holes 8, so that the upper and lower sides of the edge of the flexible tape are uniformly subjected to the wind pressure, which helps to keep the surface of the flexible tape flat and not prone to wrinkling; at the same time, it can also be applicable to tapes of different thicknesses.

[0032] In other embodiments, the gas input pipe 5 and the conveying channel 6 can also be replaced by a plurality of balls rotatably mounted on the fixing plate 32. The balls are located on the side of the fixing plate 32 close to the flexible tape, and the balls are in contact with the surface of the tape. During the movement of the sliding body 2, the balls always clamp the edge of the tape, and it is also not easy for the edge of the flexible tape to wrinkle during the movement of the sliding body 2.

[0033] Refer to Figure 2 and Figure 3 For the convenience of enabling the air flow to enter the two cavities 7 simultaneously, the conveying channel 6 includes an input section 61 and a distribution section 62. The input section 61 is opened in the fixed column 4. The input section 61 is L-shaped. One end of the input section 61 is communicated with the gas input pipe 5, and the other end is communicated with the distribution section 62. The length direction of the distribution section 62 is parallel to the length direction of the fixed column 4. The distribution section 62 has two air outlets 9. The air outlets 9 correspond to the fixing plates 32 one by one. The air outlets 9 are aligned with the side where the tape passes. The air outlets 9 are communicated with the cavities 7 in the corresponding fixing plates 32. The input section 61 is communicated in the middle of the distribution section 62. The distances from the two air outlets 9 to the connection point of the input section 61 and the distribution section 62 are equal.

[0034] The air flow entering the gas input pipe 5 is conveyed to the distribution section 62 through the input section 61, and then flows through the distribution section 62 into the cavities 7 at both ends. Since the positions of the two air outlets 9 from the connection point of the input section 61 and the distribution section 62 are equal, the fixing plates 32 on the upper and lower sides of the tape can simultaneously apply air pressure to the surface of the tape edge, ensuring the flatness effect of the flexible tape.

[0035] Refer to Figure 3 and Figure 4 To reduce gas loss, a wind limiting group 10 is provided on the fixed column 4. The wind limiting group 10 corresponds to the cavity 7 one by one. Each group of the wind limiting group 10 includes two wind limiting plates 101. The two wind limiting plates 101 are relatively fixed on both sides of the fixed column 4. The arrangement direction of the two wind limiting plates 101 in each group of the wind limiting group 10 is parallel to the conveying direction of the flexible tape, so as to reasonably block the air source from flowing into the cavity 7 on the side of the fixing plate 32 away from the tape. The wind limiting plate 101 extends into the corresponding cavity 7, and the gap between the wind limiting plate 101 and the inner wall of the corresponding cavity 7 is less than 1 mm, which not only achieves the effect of blocking the air flow, but also is not easy to affect the rotation of the fixing plate 32.

[0036] The gas entering the cavity 7 from the air outlet 9 is blocked by the two air-limiting plates 101. Although the fixing plate 32 rotates continuously, most of the gas still concentrates in the space of the cavity 7 facing the material tape, and then sprays onto the material tape from the corresponding air outlet holes 8, which helps to reduce the gas spraying out from the air outlet holes 8 on the side of the fixing plate 32 away from the material tape, thereby reducing gas loss and achieving energy conservation.

[0037] The implementation principle of the embodiment of the present invention is as follows: during the transmission of the flexible material tape, the edge of the material tape slides against the elastic layer on the guide wheel 3. Since the guide wheel 3 can rotate and the hardness of the elastic layer is small, the frictional force on the edge of the flexible material tape is small, and it is not easy to cause wear on the edge of the material tape.

[0038] When it is necessary to adjust the position of the material tape for positioning and deviation correction, the controller on the machine body 1 drives the two cylinders 11 to start. The two cylinders 11 synchronously drive the corresponding sliding bodies 2 to move in the same required direction. Then, the guide column 31 of the guide wheel 3 can drive the material tape to move horizontally. At this time, an external blower is started to respectively supply air sources to the gas input pipes 5. The air sources enter the input section 61 through the gas input pipes 5, and then enter the cavities 7 of the upper and lower fixing plates 32 of the material tape respectively from the distribution section 62 at the same time. The air flow in the cavity 7 is concentrated on one side of the cavity 7 facing the material tape under the block of the two air-limiting plates 101, and then the air flow sprays out from the multiple air outlet holes 8, so that the upper and lower sides of the edge of the flexible material tape are subjected to uniform air pressure, which helps to keep the surface of the flexible material tape flat, improve the accuracy of die-cutting and bonding, and it is not easy to form wrinkles at the edge of the flexible material tape, and to a certain extent, ensure the quality of die-cutting and bonding.

[0039] The embodiment of the present invention also discloses an automatic bonding method. The automatic bonding method uses the above-mentioned high-precision die-cutting and bonding device, and includes the following steps: Step 1: The material tape passes through the transmission and slides and laps on the two side guide wheels 3, and the guide wheels 3 are driven to rotate during the movement of the material tape; Step 2: When the cylinder 11 drives the sliding body 2 to drive the guide wheel 3 to move to correct the material tape, an external blower is started to respectively input air flows into the gas input pipes 5 on both sides of the material tape. The air flows enter the two ends of the fixing plate 32 through the input section 61 and the distribution section 62 respectively, and then spray out from the air outlet holes 8 on the fixing plate 32 facing the material tape, and uniformly apply air pressure to the upper and lower sides of the edge of the flexible material tape to keep the flexible material tape at the guide wheel 3 flat; Step 3: Then the material tape is conveyed to the bonding place for bonding or conveyed to the die-cutting place for slitting.

[0040] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
