Description

Technical Field

[0001] This utility model relates to a continuous double-sided tape application device, specifically a continuous double-sided tape application device. Background Technology

[0002] In the product packaging process, double-sided tape is often needed to be applied to the product or its packaging box. Currently, there are tape cutters on the market that can cut double-sided tape to specified lengths. However, these devices only provide the function of cutting the tape; after the machine cuts the tape, it still needs to be manually removed and applied to the product. As a single-function device, this type of equipment can assist manual production and increase some capacity, but excessive human intervention makes it unsuitable for automated production lines and cannot meet the needs of continuous, uninterrupted production. Utility Model Content

[0003] The purpose of this utility model is to provide a continuous double-sided tape application device that can achieve automated continuous double-sided tape application. It can be set to apply tape with a length of 20mm-900mm. According to the existing design, it can meet the automated production requirements of double-sided tape width within 25.4mm and tape thickness within 2mm.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A continuous double-sided tape application device includes a base and a robotic arm mounted on the base. An tape application head assembly and a tape cutting mechanism are provided at the end of the robotic arm furthest from the base. The tape application head assembly includes a fixed base plate and a material tray mounted on the fixed base plate. A tape pressing mechanism is provided below the fixed base plate. The tape pressing mechanism includes a tape dispensing cylinder and a rotating arm connected to the output end of the tape dispensing cylinder. A tensioning shaft and a tensioning wheel are mounted on the rotating arm. When the rotating arm moves, the tensioning shaft and tensioning wheel move together with the rotating arm. A material support block and a tape pressing wheel are provided below the rotating arm. A transfer plate is fixedly connected at the end of the fixed base plate furthest from the material tray. A pressing cylinder is fixed on the transfer plate. A pressing wheel is connected to the output end of the pressing cylinder. The tape cutting mechanism includes a push-shear cylinder and scissors connected to the output end of the push-shear cylinder. A telescopic cylinder is provided on one side of the push-shear cylinder.

[0005] Preferably, the base plate is fixedly connected to the end of the robot arm away from the base.

[0006] Preferably, an extension bracket is fixedly connected to the fixed base plate, and a first connecting shaft is provided at the end of the extension bracket away from the fixed base plate, and the extension bracket is connected to the material tray through the first connecting shaft.

[0007] Preferably, the end of the rotating arm away from the dispensing cylinder is connected to the fixed base plate.

[0008] Preferably, the adhesive pressing mechanism further includes a second connecting shaft, through which the adhesive dispensing cylinder is connected to the fixed base plate.

[0009] Preferably, a spring is provided on one side of the pressing roller, and the two ends of the spring are connected to the rotating arm and the pressing roller respectively. The spring can push the pressing roller downward, and the pressing roller contacts the port of the material support block under the spring's thrust. When there is double-sided tape at this contact point, the pressing action can be realized.

[0010] Preferably, the push-shear cylinder is fixed on the telescopic cylinder, and the telescopic cylinder is fixed on the adapter plate.

[0011] Preferably, it also includes a clamp and a frame disposed below the clamp, the frame being located on one side of the base and the clamp being located below the adhesive applicator head assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a dispensing cylinder to drive a rotating arm downwards, causing the pressure roller to contact the product. After the pressure roller contacts the product, the robotic arm continues to move downwards. When the gap between the pressure roller and the material support block is greater than the thickness of the double-sided tape, the robotic arm can dispensing the tape by moving left and right. Subsequently, the robotic arm controls the pressing cylinder to extend, driving the pressing roller to press the double-sided tape. This achieves automatic dispensing and pressing of the double-sided tape, eliminating the hassle of manually applying double-sided tape.

[0014] 2. By driving the dispensing cylinder to retract and causing the rotating arm to rise, the clamping cylinder remains stationary, creating a height difference between the clamping wheel and the pressing wheel. The telescopic cylinder drives the cutting mechanism to extend outward through the gap between the clamping wheel and the pressing wheel, and the push-shear cylinder pushes the scissors to cut the double-sided tape, thus realizing automatic tape cutting. This eliminates the trouble of manual tape cutting, improves the degree of automation and efficiency, and only requires manual loading and unloading, thereby greatly reducing the labor intensity of employees.

[0023] Please see Figures 1 to 4This utility model provides an embodiment of a continuous double-sided tape application device, comprising a base 1 and a robotic arm 2 mounted on the base 1. An tape application head assembly 3 and a tape cutting mechanism 4 are provided at the end of the robotic arm 2 furthest from the base 1. The tape application head assembly 3 includes a fixed base plate 31 and a material tray 34 mounted on the fixed base plate 31. The fixed base plate 31 is fixedly connected to the end of the robotic arm 2 furthest from the base 1. An extension bracket 32 ​​is fixedly connected to the fixed base plate 31. A first connecting shaft 33 is provided at the end of the extension bracket 32 ​​furthest from the fixed base plate 31, and the extension bracket 32 ​​is connected via the first connecting shaft. 33 is connected to the material tray 34. A pressing mechanism 35 is provided below the fixed base plate 31. The pressing mechanism 35 includes a dispensing cylinder 351 and a rotating arm 352 connected to the output end of the dispensing cylinder 351. The end of the rotating arm 352 away from the dispensing cylinder 351 is connected to the fixed base plate 31. A tensioning shaft 353 and a tensioning wheel 354 are installed on the rotating arm 352. When the rotating arm 352 moves, the tensioning shaft 353 and the tensioning wheel 354 move together with the rotating arm 352. A material support block 355 and a pressing wheel 356 are provided below the rotating arm 352. One side of the pressing wheel 356... A spring is provided, with its two ends connected to the rotating arm 352 and the pressure roller 356, respectively. The spring can push the pressure roller 356 downward, causing it to contact the end of the material support block 355 under the spring's force. When double-sided tape 39 is present at this contact point, the pressing action is achieved. The pressing mechanism 35 also includes a second connecting shaft 357, through which the dispensing cylinder 351 is connected to the fixed base plate 31, allowing the dispensing cylinder 351 to rotate with the second connecting shaft 357. A transition plate 36 is fixedly connected to the end of the fixed base plate 31 away from the material tray 34. A clamping cylinder 37 is fixed on the 36, and a clamping wheel 38 is connected to the output end of the clamping cylinder 37. The clamping wheel 38 is used to clamp the double-sided tape 39. The tape cutting mechanism 4 includes a push-shear cylinder 41 and scissors 42 connected to the output end of the push-shear cylinder 41. A telescopic cylinder 43 is provided on one side of the push-shear cylinder 41. The push-shear cylinder 41 is fixed on the telescopic cylinder 43, and the telescopic cylinder 43 is fixed on the adapter plate 36. The continuous double-sided tape application equipment also includes a clamp 5 and a frame 6 set below the clamp 5. The frame 6 is located on one side of the base 1, and the clamp 5 is located below the tape application head assembly 3.

[0024] In this invention, the pressure roller 356, under the spring force, contacts the port of the material support block 355 downwards. When double-sided tape 39 is present at this contact point, the pressure action is achieved. When the equipment applies double-sided tape 39, the dispensing cylinder 351 extends first. As the dispensing cylinder 351 extends, its connecting shaft rotates, causing a change in the angle of the dispensing cylinder 351. The dispensing cylinder 351 then pushes the rotating arm 352 downwards, causing the pressure roller 356 to contact the product. The robotic arm 2 then applies the adhesive. After the roller 356 contacts the product, it continues to move downward. At this time, the spring force behind the pressure roller 356 is less than the reaction force of the product pushing the pressure roller 356, so the pressure roller 356 will move upward. When the gap between the pressure roller 356 and the material support block 355 is greater than the thickness of the double-sided tape 39, the robot arm 2 can move left and right to realize the glue dispensing action. When the glue dispensing length exceeds 5mm, the robot arm 2 can control the clamping cylinder 37 to extend, driving the clamping roller 38 to realize the action of clamping the double-sided tape 39.

[0025] When it is necessary to cut the double-sided tape 39, the glue dispensing cylinder 351 retracts, driving the rotating arm 352 to rise. At this time, the clamping cylinder 37 remains stationary, and a height difference appears between the clamping wheel 38 and the glue pressing wheel 356. The telescopic cylinder 43 drives the entire tape cutting mechanism 4 to extend outward through the gap between the clamping wheel 38 and the glue pressing wheel 356. The push-cutting cylinder 41 pushes the scissors 42 to cut the double-sided tape 39, thus realizing the tape cutting action.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
