Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and more specifically to an adhesive applicator. Background Technology

[0002] In many industries such as electronics manufacturing, automotive parts processing, and packaging, it is often necessary to apply 3M tape to products. During application, the 3M adhesive leaves the product, and then the release liner is peeled off, which is then recycled. Currently, these operations are mostly done manually, which is not only inefficient and labor-intensive, but also makes it difficult to guarantee the precision and consistency of manual operations, easily leading to inconsistent product quality. In addition, the manual handling of release liner and residual adhesive can also cause environmental pollution.

[0003] While some single-function automated devices exist in the existing technology, such as automatic label peelers and automatic adhesive applicators, these devices can only perform single-function operations. Therefore, it is necessary to develop an adhesive applicator that can automatically peel off 3M adhesive, apply 3M adhesive, tear off release paper, and recycle release paper. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the object of the present invention is to provide an adhesive application device with a simple structure that can automatically peel off adhesive, apply adhesive, tear release paper, and automatically recycle release paper, thereby improving production efficiency, ensuring product quality, and reducing environmental pollution.

[0005] To achieve the above objectives, the present invention provides an adhesive applicator, comprising:

[0006] A conveyor line used for conveying products;

[0007] The adhesive stripping unit includes a rotating wheel for holding 3M film rolls, a recovery roller for recovering substrates of 3M adhesive, and a stripping plate for peeling off 3M adhesive.

[0008] The adhesive application unit includes a robotic arm, an adhesive application head, a folding edge component, and a pressing edge component. The robotic arm is connected to the adhesive application head, which is equipped with an adsorption component for adsorbing the 3M adhesive. The folding edge component can move and abut against the release paper extending from the end of the adhesive application head to fold the release paper upward. The pressing edge component is disposed on the adhesive application head to clamp and fix the folded part of the release paper.

[0009] A release paper separation unit, the release paper separation unit including a separation rod, the separation rod being movable back and forth to make moving contact with the bottom surface of the release paper, thereby separating the release paper from the 3M adhesive;

[0010] A release paper collection unit includes a tank, the top of which is open to allow the adhesive applicator to insert the release paper into the tank. The tank is provided with a waste suction port for removing the separated release paper.

[0011] According to the present invention, an adhesive applicator peels off the 3M adhesive from the film roll using a peeling unit, then applies the peeled 3M adhesive using an applicator that adsorbs the adhesive, folds the release paper, and clamps and fixes the folded release paper, attaching the adhesive side of the 3M adhesive to the product. A release paper separation unit then separates the release paper from the adhesive, and the applicator head moves to a release paper collection unit to remove the release paper. This adhesive applicator has a simple structure and can automatically complete the peeling, applicating, release paper removal, and release paper recycling processes, thereby improving production efficiency, ensuring product quality, and reducing environmental pollution.

[0012] In addition, the adhesive applicator according to the embodiments of the present invention may also have the following additional technical features:

[0013] Optionally, the tank is provided with an air blowing port to blow off the separated release paper.

[0014] Furthermore, the waste suction port is located at one end of the tank, and the air blowing port is located at the other end of the tank.

[0015] Optionally, the adhesive application unit includes a camera for determining the position of the 3M adhesive adsorbed by the application head, and the folding edge is disposed on both sides of the camera.

[0016] Furthermore, the folded edge component can be raised or lowered.

[0017] Optionally, the pressing element may be positioned near or away from the end of the adhesive applicator to collectively create a clamping space for holding the folded part of the release paper.

[0018] Furthermore, the adhesive stripping unit is located on one side of the conveyor line, the robotic arm is located on the other side of the conveyor line, the camera and the folding piece are located between the adhesive stripping unit and the conveyor line, and the release paper collection unit is located above the conveyor line.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] The following is for reference. Figures 1-6 The implementation of the adhesive applicator proposed in the embodiments of the present invention will be described in detail.

[0033] An adhesive applicator according to an embodiment of the present invention includes:

[0034] Conveyor line 1, conveyor line 1 is used to convey product 11;

[0035] The adhesive stripping unit 2 includes a rotating wheel 21 for holding 3M film rolls, a recycling roller 22 for recycling substrates of 3M adhesive, and a stripping plate 23 for peeling off 3M adhesive.

[0036] The adhesive applicator unit 3 includes a robotic arm 31, an adhesive applicator head 32, a folding edge member 33, and a pressing edge member 34. The robotic arm 31 is connected to the adhesive applicator head 32, which is equipped with an adsorption member for adsorbing 3M adhesive. The folding edge member 33 can move and abut against the release paper extending from the end of the adhesive applicator head 32 to fold the release paper upward. The pressing edge member 34 is disposed on the adhesive applicator head 32 to clamp and fix the folded part of the release paper.

[0037] Release paper separation unit 4 includes a separation rod 41, which is movable back and forth to make contact with the bottom surface of the release paper, thereby separating the release paper from the 3M adhesive.

[0038] Release paper collection unit 5 includes a tank 51 with an open top to allow the adhesive applicator 32 to insert the release paper into the tank 51. The tank 51 is provided with a waste suction port 52 for removing the separated release paper.

[0039] In other words, multiple products 11 are arranged on the conveyor line 1 and the products 11 are conveyed. The peeling unit 2 is located on one side of the conveyor line 1. The 3M film rolls on the peeling unit 2 are placed on the rotating wheel 21. The pull-out section of the 3M film roll is wound around the peeling plate 23, and the discharge end of the 3M film roll is wound around the recycling roller 22 for recycling the substrate of the 3M adhesive. The 3M adhesive is conveyed back and forth at the edge of the peeling plate 23, so that the 3M adhesive is peeled off from the substrate. The 3M adhesive is in the shape of a strip. The length of the release paper on the 3M adhesive is greater than the length of the adhesive under the release paper. The robotic arm 31 drives the applicator head 32 to absorb and transfer the peeled 3M adhesive to the position of the folding member 33. The relative movement of the applicator head 32 and the folding member 33 in the vertical direction causes the folding member 33 to move and abut against the release paper extending from the applicator head 32, so that the release paper is folded upward. The pressing member 34 then clamps and fixes the folded part, so that the 3M adhesive is peeled off. While the adhesive applicator 32 remains relatively fixed, the robotic arm 31 moves the adhesive applicator 32 to the product 11 with adhesive on the conveyor line 1 and lowers it to attach the 3M adhesive to the product 11. The robotic arm 31 then raises the adhesive applicator 32 a certain distance, causing the 3M adhesive to initially separate from the release paper. The adhesive and release paper form an angle at the separation point. The separation rod 41 then moves from the angle between the two towards the unseparated direction and moves to contact the bottom surface of the release paper, causing the release paper to gradually separate from the adhesive. The robotic arm 31 then moves the adhesive applicator 32 to the top opening of the tank 51, so that the release paper is located inside the tank 51. The adhesive applicator 32 can block or partially block the top opening of the tank 51, which can prevent the release paper from falling outside the tank 51 when the pressing part 34 releases the release paper. At the same time, it can improve the suction capacity of the waste suction port 52 for the release paper, so that the release paper is sucked to the waste collection point.

[0040] The conveyor line 1 can use a belt conveyor in conjunction with fixture 12 for transport. The product 11 is placed on fixture 12 for easy positioning. The conveyor line 1 is equipped with positioning components 13 for blocking and releasing fixture 12, so that the product 11 can be accurately stopped at the position where adhesive is to be applied. The product 11 can be frame-shaped, and fixture 12 can be positioned from the inner frame of product 11. Positioning components 13 can block and release fixture 12 by lifting. The 3M adhesive can be transported by rollers clamping and rolling the pull-out section of the 3M adhesive, or by the recovery roller 22 when recovering the substrate. The adsorption component can be several adsorption holes on the bottom surface of the adhesive head 32 to fix the 3M adhesive by adsorption. The folding component 33 can be fixed or movable. When component 33 is fixed, the robotic arm 31 can drive the adhesive applicator 32 to move vertically, so that the protruding part of the release paper moves relative to the folding component 33 to achieve folding. Folding can also be achieved by the vertical movement of the folding component 33. The folding component 33 can be provided with a bevel to facilitate the folding of the release paper. The pressing component 34 can be driven by a cylinder to clamp. The pressing component 34 can be provided with a separate gripper to clamp the flipped part of the release paper, or the folded part of the release paper can be pressed onto the adhesive applicator 32 to clamp the folded part. The separating rod 41 can be a horizontally arranged round rod. The separating rod 41 can be moved back and forth by a motor in conjunction with a sliding rod structure. The number and direction of movement of the separating rod 41 can be set according to the number and position of the 3M adhesive applied to the product 11.

[0041] Therefore, the 3M adhesive is peeled off the film roll by the peeling unit 2, and then the adhesive application unit 3 adsorbs the peeled 3M adhesive, folds the release paper, and clamps and fixes the folded release paper, attaching the adhesive side of the 3M adhesive to the product 11. The release paper separation unit 4 then separates the 3M adhesive release paper from the adhesive, and the application head 32 moves to the release paper collection unit 5 to remove the release paper. This adhesive application device has a simple structure and can automatically peel, apply, tear, and recycle the release paper, which helps improve production efficiency, ensures the quality of product 11, and reduces environmental pollution.

[0042] Optionally, the tank 51 is provided with an air blowing port 53 to blow off the separated release paper. Understandably, when the pressing member 34 is released, electrostatic attraction may exist between the release paper and the adhesive applicator 32, preventing complete detachment or resulting in a slow detachment speed. The air blowing port 53 allows the release paper to be quickly blown off the adhesive, facilitating the rapid removal of the release paper by the waste suction port 52. The blowing and suction actions can be performed simultaneously, and the air blowing port 53 and waste suction port 52 can be connected to an external air source via pipes. The cross-section of the tank 51 can be U-shaped.

[0043] Furthermore, the waste suction port 52 is located at one end of the tank 51, and the air blowing port 53 is located at the other end of the tank 51. Understandably, the relative arrangement of the air blowing port 53 and the waste suction port 52 allows the release paper to be blown towards the waste suction port 52 during air blowing. The long strip of release paper can fall from the adhesive applicator 32 and form a bend, facilitating the quick removal of the release paper by the waste suction port 52. The tank 51 is positioned directly above the product 11, allowing the adhesive applicator 32 to apply adhesive to the product 11 from both sides of the tank 51. The product 11 can be frame-shaped.

[0044] Optionally, the adhesive application unit 3 includes a camera 35, which is used to determine the position of the 3M adhesive adsorbed by the application head 32. Folding elements 33 are disposed on both sides of the camera 35. Understandably, since there may be relative positional deviations when the application head 32 adsorbs the 3M adhesive, taking photos from below with the camera 35 allows the position of the 3M adhesive on the application head 32 to be determined. Then, the control system calculates and controls the robotic arm 31 to accurately apply the 3M adhesive to the product 11, ensuring the accuracy of the application. By disposing of the folding elements 33 on both sides of the camera 35, the 3M adhesive on the application head 32 can move and contact the folding elements 33 while being moved to the camera 35 for photo taking. This avoids complex movements, improves efficiency, and allows the robotic arm 31 to adjust its position by taking photos at this station, ensuring a more precise relative position of the folding elements 33 with the release paper, thus guaranteeing the reliability of the folding.

[0045] Furthermore, the folding element 33 can be raised and lowered. Understandably, by raising and lowering the folding element 33, it can actively approach the release paper on the adhesive applicator 32, avoiding relative movement and contact between the release paper and the folding element 33 caused by the descent of the heavier adhesive applicator 32, which would affect the stability and speed of the operation. The folding element 33 can achieve the folding of the release paper by using a cylinder for raising and lowering.

[0046] Optionally, the pressing element 34 can be positioned near or away from the end of the adhesive applicator 32 to collectively create a clamping space for holding the folded part of the release paper. Understandably, by positioning the pressing element 34 near or away from the end of the adhesive applicator 32, the clamping space is closed and opened. This utilizes the simple structure of the ends of the pressing element 34 and the adhesive applicator 32 to achieve the clamping and releasing of the release paper, which is beneficial for saving space and cost. The pressing element 34 can be driven by a cylinder to move near or away from the end of the adhesive applicator 32. The contact point between the pressing element 34 and the release paper can be configured as concave-convex.

[0047] Furthermore, the peeling unit 2 is positioned on one side of the conveyor line 1, the robotic arm 31 is positioned on the other side of the conveyor line 1, the camera 35 and the folding component 33 are positioned between the peeling unit 2 and the conveyor line 1, and the release paper collection unit 5 is positioned above the conveyor line 1. Understandably, this rational arrangement improves the continuity of movements, prevents the robotic arm 31 from causing large-scale movement of the adhesive applicator 32, and helps improve overall work efficiency.

[0048] Optionally, the robotic arm 31 includes an X-axis movement drive 311, a Y-axis movement drive 312, a Z-axis movement drive 313, and a rotary drive 314. The adhesive applicator 32 is connected to the output end of the rotary drive 314, the rotary drive 314 is connected to the output end of the Z-axis movement drive 313, the Z-axis movement drive 313 is connected to the output end of the Y-axis movement drive 312, and the Y-axis movement drive 312 is connected to the output end of the X-axis movement drive 311. Understandably, this configuration enables the adhesive applicator 32 to perform both horizontal and vertical movement, facilitating operations such as adhesive pickup, application, release paper removal, and release paper collection, thus saving costs compared to a robot. The rotary drive 314 enables the adhesive applicator 32 to rotate. When only one end of the 3M adhesive release paper protrudes from the adhesive, the folding edge member 33 and the pressing edge member 34 can each be provided in only one form, or both can be activated. By rotating the adhesive applicator 32 180°, the end of the release paper protruding from the adhesive is directed towards the position of the separating rod 41, facilitating the separation of the release paper by the separating rod 41. The X-axis movement drive 311, Y-axis movement drive 312, and Z-axis movement drive 313 can be motor-driven module structures, while the rotary drive 314 can be a motor or a rotary cylinder.

[0049] Optionally, the release paper separation unit 4 also includes a rolling element 42, which is disposed on the front and rear sides of the separation rod 41. The rolling element 42 can move synchronously with the separation rod 41 to roll the adhesive adhered to the product 11. Understandably, when the adhesive applicator 32 applies 3M adhesive to the product 11, and the robotic arm 31 lifts the adhesive applicator 32 a certain distance, or when the separation rod 41 separates the release paper, it may cause pulling on the adhesive. This is not conducive to the adhesive adhering completely to the product 11. By having the rolling element 42 move synchronously with the separation rod 41, not only can the adhesive be rolled to ensure complete adhesion to the product 11, but the operation is also simpler, improving work efficiency. The contact position between the rolling element 42 and the adhesive can be configured with multiple rows of teeth or multiple rows of thin edges to reduce the adhesion force between the rolling element 42 and the adhesive.
