Description

Technical Field

[0001] The invention belongs to the technical field of double-sided adhesive tape grasping and sticking devices, and in particular belongs to a multifunctional double-sided adhesive tape grasping and sticking device. Background Art

[0002] In the process of laminating long-strip adhesive auxiliary materials, traditional processes face significant technical bottlenecks: the vacuum adsorption laminating method used in the early days leads to sealing failure due to the irregular shape of the auxiliary materials, which is very prone to air leakage and cannot stably grasp double-sided tapes made of materials such as PET and foam; while the rolling laminating mechanism is limited by the regularity of the auxiliary materials and is difficult to adapt to adhesive parts with complex contours.

[0003] The subsequent needle-shaped gripping technology solved the gripping needs of some special-shaped auxiliary materials. However, due to the single adaptability of the needle-shaped chassis to materials, it can only adapt to a single material double-sided tape. When facing multi-material mixed scenarios such as 3M glue, VHB glue, foam glue and water glue, there are defects such as poor gripping stability and high glue surface damage rate. Traditional narrow-edge or serrated pressure plates are prone to bulging, bubbles and residual glue on the glue surface during attachment, affecting product yield. Summary of the Invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a multifunctional double-sided adhesive tape grasping device.

[0005] The technical solution adopted by the present invention is as follows: a multifunctional double-sided tape grasping and pasting device, including a cutter disc upper plate, on which a material picking mechanism and a material pasting mechanism are provided, the material picking mechanism includes a sliding cylinder installed at the bottom of the cutter disc upper plate, the movable end of the sliding cylinder is fixedly connected to the cutter disc, and two adjacent edges of the cutter disc are installed with blades, and the cutting edges of the two blades are both facing the outside of the cutter disc, forming an L-shaped grasping structure; the material pasting mechanism includes a cylinder fixing part installed on the side of the cutter disc upper plate, a three-rod cylinder is installed on the cylinder fixing part, and the movable end of the three-rod cylinder is fixedly connected to the pressing plate.

[0006] Furthermore, the blade is a long flat plate structure.

[0007] Furthermore, the cutting edge of the blade is a straight cutting edge.

[0008] Furthermore, the blade is detachably connected to the cutter disc via a cutter disc pressing piece.

[0009] Furthermore, the cutter disc pressing plate is also a long flat plate structure.

[0010] Furthermore, two pressing plates are provided, and the two pressing plates are respectively arranged above the two blades, and the two pressing plates are fixedly connected by a pointed connector.

[0011] Furthermore, the bottom surface of the pressing plate is a plane.

[0012] Furthermore, the length of the pressing plate is not less than the length of the blade, and the width of the pressing plate is not less than the width of the double-sided adhesive material on the blade.

[0013] Furthermore, a robot end flange for connecting to an external robotic arm is installed on the top of the cutter head upper plate.

[0014] Furthermore, two electric reversing valves are installed above the upper plate of the cutter disc. The two electric reversing valves are respectively connected to the air circuits of the three-rod cylinder and the sliding cylinder, and drive the three-rod cylinder and the sliding cylinder by controlling the gas flow direction.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] This multifunctional double-sided tape grabbing device uses two blades to form an L-shaped grabbing structure to grab the double-sided tape, abandoning the traditional needle-shaped chuck and vacuum suction sealing method, solving the problems of bending deformation and single material requirements when grabbing auxiliary materials.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] The following combination Figure 1-Figure 5 The present invention is described in detail.

[0028] Example

[0029] Example 1

[0030] like Figure 1 As shown, a multifunctional double-sided tape grabbing and pasting device includes a cutter disc upper plate 1, on which a material picking mechanism and a material pasting mechanism are provided. The cutter disc upper plate 1 is used to support and fix the material picking mechanism and the material pasting mechanism.

[0031] like Figure 4As shown, the reclaiming mechanism includes a sliding cylinder 3 mounted on the bottom of the cutterhead upper plate 1. The movable end of the sliding cylinder 3 is fixedly connected to the cutterhead 2. The fixed end of the sliding cylinder 3 is screwed to the bottom of the cutterhead upper plate 1, while the movable end is also screwed to the cutterhead 2. It is worth noting that the cylinder body of the sliding cylinder 3 is the movable end, while the cylinder rod is the fixed end.

[0032] Blades 5 are mounted on two adjacent edges of the cutter disc 2, with the cutting edges of both blades 5 facing outward from the disc 2, forming an L-shaped gripping structure. This L-shaped gripping structure not only provides a smooth and precise grip without causing bending or deformation of product accessories, but also, compared to existing needle-shaped chucks and vacuum sealing methods, is not limited to a single accessory material and is compatible with multiple double-sided adhesives, including 3M adhesive, VHB adhesive, foam adhesive, and Sekisui adhesive. Its application scenarios extend to processes such as touch screen frame adhesive and backlight conductive adhesive, offering a wider range of applicability.

[0033] Preferably, the blade 5 is a long flat plate structure, the cutting edge of the blade 5 is a straight cutting edge, and the cutting edge width is 0.5-2 mm.

[0034] The blade 5 is detachably connected to the cutter disc 2 via the cutter disc pressure plate 4, which is also a long, flat plate. The cutter disc pressure plate 4 is fixed to the surface of the cutter disc 2 by screws. Loosening the screws and removing the cutter disc pressure plate 4 allows the blade 5, which is fixed between the cutter disc pressure plate 4 and the cutter disc 2, to be removed, making it easier to replace the blade 5 later.

[0035] During the specific implementation, it is worth noting that an anti-slip pad such as a silicone pad can be added between the cutter disc pressing plate 4 and the blade 5 to prevent the blade 5 from loosening.

[0036] like Figure 1 、 Figure 3 and Figure 5 As shown, the material feeding mechanism includes a cylinder fixing part 7 mounted on the side of the cutter head upper plate 1, on which a three-rod cylinder 8 is mounted, and the movable end of the three-rod cylinder 8 is fixedly connected to a pressing plate 9. In addition, two pressing plates 9 are provided, and the two pressing plates 9 are respectively arranged above the two blades 5.

[0037] like Figure 2 As shown, the two pressing plates 9 are fixedly connected by a pointed connector 11. The two pressing plates 9 are connected by the pointed connector 11 to form an L-shaped overall structure. The design of the pointed connector 11 can reduce stress concentration during pressing.

[0038] Since there are two pressing plates 9, two groups of three-rod cylinders 8 are provided correspondingly. The two groups of three-rod cylinders 8 are symmetrically installed on both sides of the cutter head upper plate 1 to further ensure uniform pressure distribution.

[0039] The bottom surface of the pressing plate 9 is flat, which abandons the existing narrow edge and serrated pressing plate attachment method, and solves the problems of bulging and bubbling of the auxiliary material and residual glue during attachment.

[0040] During the specific implementation, it is worth noting that the length of the pressing plate 9 is not less than the length of the blade 5 , and the width of the pressing plate 9 is not less than the width of the double-sided adhesive material on the blade 5 .

[0041] The wide pressing plate 9 allows the entire strip of adhesive to completely contact the product surface, preventing bulges and adhesive residue from forming on the product, thus reducing the defective rate. During application, the pressing plate 9 is driven downward by the three-rod cylinder 8, pressing the double-sided adhesive tape evenly onto the target surface.

[0042] A robot end flange 10 is mounted on the top of the cutter head upper plate 1, for connecting to an external robotic arm. A CCD vision camera is also mounted on the main unit to locate the double-sided adhesive tape and the target product. The CCD vision camera is connected to the robotic arm control system to precisely calibrate the gripping position.

[0043] Two electric reversing valves 6 are mounted above the cutterhead upper plate 1. These valves are connected to the pneumatic circuits of the three-rod cylinder 8 and the sliding cylinder 3, respectively, and control the flow of gas to drive the three-rod cylinder 8 and the sliding cylinder 3. The electric reversing valves 6 are two-position, five-way solenoid valves. The PLC control system sends electrical signals to switch the pneumatic circuits, achieving sequential control of the cylinder movements.

[0044] Through the ingenious arrangement of the three-rod cylinder 8, the sliding cylinder 3 and the electric reversing valve 6, the device has a simple structure and light weight, and its material taking and pressing stability is improved.

[0045] Specifically, when using the multifunctional double-sided adhesive tape grasping device, the working process is as follows:

[0046] Step 1: Grasping stage: The CCD vision camera locates the double-sided adhesive material, the robotic arm drives the device to move to the target position, the electric reversing valve 6 controls the gas flow to the sliding cylinder 3, and drives the blade 5 to scoop up the double-sided adhesive horizontally;

[0047] Step 2: Attachment stage: The CCD vision camera locates the target product, the robotic arm moves to the attachment position, the blade 5 first touches the target surface, and then the electric reversing valve 6 controls the gas flow to the two three-rod cylinders 8, synchronously driving the pressing plate 9 downward to press the double-sided tape flatly;

[0048] Step 3: Reset stage: the electric reversing valve 6 controls the sliding cylinder 3 to drive the blade 5 to retreat and peel, and the three-rod cylinder 8 drives the auxiliary material bonding press plate 9 to reset, completing the attachment cycle.

[0049] Example 2

[0050] In this embodiment, the retrieving mechanism replaces the sliding cylinder 3 with a high-precision electric linear module. This module is mounted on the bottom of the cutterhead upper plate 1, with its slider connected to the cutterhead 2 via an adapter plate. Compared to the sliding cylinder 3, the electric linear module offers higher positioning accuracy, more stable motion speed, and precise displacement control. This allows for more precise control of the gripping action of the blade 5, making it particularly suitable for gripping ultra-thin double-sided tape, which requires extremely high precision.

[0051] Example 3

[0052] On the basis of the first embodiment, this embodiment further optimizes the material-painting mechanism, and the three-rod cylinder 8 installed on the cylinder fixing part 7 is replaced by a servo electric cylinder. Compared with the three-rod cylinder 8, the servo electric cylinder has higher force control accuracy and position control accuracy, and can accurately control the downward pressure and stroke of the pressing plate 9 according to the double-sided tape of different materials and thicknesses. The surface of the pressing plate 9 is specially treated and sprayed with a layer of nano-coating with anti-sticking properties. The nano-coating can effectively prevent the double-sided tape from adhering to the pressing plate 9 during the lamination process, further avoiding the occurrence of residual glue problems, and also facilitates the cleaning and maintenance of the pressing plate 9.

[0053] In addition to mounting the robot's end flange 10, the top of the cutter head upper plate 1 also incorporates a force sensor. This force sensor, connected to the robotic arm control system, monitors the pressure applied by the press plate 9 to the double-sided tape in real time during the attachment process and feeds this pressure data back to the control system. The control system automatically adjusts the output force of the servo electric cylinder based on preset pressure parameters, achieving closed-loop pressure control and further improving attachment quality.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
