Description

Technical Field

[0001] This utility model relates to the technical field of tape adhesion testing, and in particular to a tape constant pressure adhesion device. Background Technology

[0002] Adhesive tape, as a common bonding material, is widely used in many fields such as packaging, electronics, automotive, construction, and medical. For example, in the packaging industry, tape is used for sealing boxes and bundling to ensure the safety of goods during transportation and storage; in the electronics industry, tape is used to fix electronic components and shield against electromagnetic interference. The adhesive properties of tape directly affect its performance and product quality. Poor adhesive properties can lead to problems such as packaged goods scattering and electronic components falling off, causing inconvenience in production and use, and even safety hazards and economic losses. Therefore, accurately assessing the adhesive properties of tape is crucial for ensuring product quality, improving production efficiency, and reducing production costs.

[0003] Currently, in tape adhesion testing, the tape is usually manually adhered to a standard carrier plate before testing. Chinese utility model patent (CN208060367U) discloses a constant-pressure tape adhesion mechanism that uses the weight of a rolling roller to provide constant pressure during the adhesion process, ensuring the tape adheres evenly to the standard carrier plate and avoiding abnormal adhesion force measurements caused by the adhesion process.

[0004] However, this design still has some shortcomings. When the compaction rollers rely solely on static pressure, the tape exhibits a situation where the surface is compressed first, while the internal compaction is relatively insufficient. This is especially true for thicker tapes, where static pressure struggles to effectively penetrate the tape and achieve sufficient compaction. This results in uneven compaction within the tape, which in turn severely affects the accuracy and reliability of the adhesion parameter determination. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a constant pressure adhesive tape bonding device, which can vibrate and roll the adhesive tape through a roller pressing mechanism, effectively overcoming the shortcomings of existing designs that rely on self-weight pressure, and significantly improving the adhesive force and accuracy of the adhesive tape bonding parameters.

[0007] To achieve the above objectives, this utility model proposes a constant pressure adhesive tape bonding device, comprising a base, a mounting frame, and a roller pressing mechanism. The base has an adhesive area, and a sliding table module is provided on one side of the adhesive area. One side of the mounting frame is connected to the sliding table of the sliding table module. The roller pressing mechanism includes a roller, a drive shaft disposed within the roller, multiple circumferentially distributed vibrating elements, and limiting frames. The drive shaft has a concave-convex structure sleeved on its outer side, the concave-convex structure including multiple circumferentially distributed protrusions. The drive shaft is movably mounted on the multiple limiting frames. The inner side of the drive shaft extends to the outer side of the roller and is movably connected to the mounting frame. The mounting frame is provided with a linkage assembly connected to the drive shaft. Each vibrating element includes a vibrating shaft and two limiting rods respectively provided on both sides of the vibrating shaft. The two ends of the vibrating shaft can abut against the protrusion and the inner wall of the roller, respectively. One end of the limiting rod is provided with a straight groove, and the other end of the limiting rod extends to the outer side of the roller and is connected to the mounting frame. The central axis of each vibrating element is located in the corresponding straight groove.

[0008] In addition, the tape constant pressure bonding device proposed in the application may also have the following additional technical features:

[0009] Specifically, the linkage component includes a meshing gear and a rack, wherein the gear is connected to one end of the drive shaft, the rack is located on one side of the slide module, and the rack is arranged along the direction of the slide module.

[0010] Specifically, it also includes an auxiliary roller, which is at the same height as the roller, and both sides of the auxiliary roller are connected to the mounting frame via connecting rods.

[0011] Specifically, the other side of the mounting frame is arranged in an inverted U-shape, and the roller pressing mechanism is located inside the mounting frame.

[0012] Specifically, the outer edge of the protrusion is streamlined.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. The roller pressing mechanism can vibrate and press the tape, which effectively overcomes the shortcomings of the existing design that relies on self-weight pressure, and significantly improves the adhesive force and accuracy of the adhesive parameters.

[0015] 2. As the mounting frame moves, driving the rollers across the tape surface, the drive shaft rotates continuously under the coordinated action of the linkage components. Multiple protrusions on the outer side of the drive shaft rotate synchronously, continuously actuating the vibrating shaft. This actuation generates a continuous and regular motion, constantly impacting the rollers. This impact force is transmitted to the tape through the rollers, subjecting the tape to more complex and effective pressure during the bonding process. Compared to gravity-based pressure, vibrating roller pressure breaks down the original stress distribution on the tape surface, allowing the adhesive to penetrate and diffuse better, thus effectively improving the tape's adhesion and ensuring the accuracy of bonding parameters.

[0016] 3. Multiple vibration shafts are distributed around the roller, which can apply continuous and stable vibration force to the roller from all directions. This all-round vibration force ensures that the roller maintains constant pressure on the conveyor belt as it moves across the belt surface.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The constant pressure adhesive tape device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, the constant pressure adhesive tape device of this utility model embodiment may include a base 10, a mounting frame 60, and a roller pressing mechanism 20.

[0027] The base 10 has an adhesive area 101, and a slide module 102 is provided on one side of the adhesive area 101. One side of the mounting bracket 60 is connected to the slide of the slide module 102. The slide module 102 described in this embodiment has the function of controlling the slide on it to move along its direction. This is prior art and will not be described in detail here. The slide module 102 can drive the mounting bracket 60 to move linearly, so that the mounting bracket 60 can pass through the adhesive area 101.

[0028] The other side of the mounting bracket 60 is arranged in an inverted U-shape. The roller pressing mechanism 20 is located inside the mounting bracket 60. The roller pressing mechanism 20 may include a roller 201 and a drive shaft 202 disposed inside the roller 201, a plurality of circumferentially distributed vibrating elements 203 and a limiting frame 204. The drive shaft 202 is provided with a concave-convex structure 30 on its outer side. The concave-convex structure 30 may include a plurality of circumferentially distributed protrusions 301. The outer edge of the protrusions 301 is arranged in a streamlined shape.

[0029] The drive shaft 202 is movably disposed inside the plurality of limit frames 204, and both ends of the drive shaft 202 extend to the outside of the roller 201 and are movably connected to the mounting frame 60. The mounting frame 60 is provided with a linkage assembly 40 connected to the drive shaft 202. The linkage assembly 40 may include a meshing gear 401 and a rack 402, wherein the gear 401 is connected to one end of the drive shaft 202, and the rack 402 is disposed on one side of the slide module 102 and is arranged along the direction of the slide module 102. During the movement of the mounting frame 60, the linkage assembly 40 described in this embodiment enables the mounting shaft to rotate continuously.

[0030] Each vibrating element 203 may include a vibrating shaft 2031 and two limiting rods 2032 respectively disposed on both symmetrical sides of the vibrating shaft 2031. The two ends of the vibrating shaft 2031 can respectively abut against the protrusion 301 and the inner wall of the roller 201. One end of each limiting rod 2032 has a straight groove 20321, and the other end extends to the outside of the roller 201 and is connected to the mounting bracket 60. The central axis of each vibrating element 203 is located within the corresponding straight groove 20321. In this embodiment, the straight groove 20321 is located radially on the roller 201.

[0031] In this embodiment, multiple vibration shafts 2031 are distributed around the roller 201, which can apply continuous and stable vibration force to the roller 201 from all directions. This omnidirectional vibration force ensures that the roller 201 maintains constant pressure on the tape during its movement across the tape surface.

[0032] Specifically, in the actual adhesive bonding test, the personnel first adhere the adhesive tape to be tested to the bonding area 101. Then, the mounting frame 60 is moved by the slide module 102, causing the mounting frame 60 to drive the roller 201 to move on the tape surface. During this process, the drive shaft 202 rotates continuously under the coordinated action of the linkage component 40. Multiple protrusions on the outer side of the drive shaft 202 rotate synchronously, and these protrusions continuously agitate the vibration shaft 2031. After being agitated, the vibration shaft 2031 generates continuous and regular motion, thereby continuously impacting the roller 201. This impact force is transmitted to the tape through the roller 201, subjecting the tape to more complex and effective pressure during the bonding process. Compared with self-weight pressure, vibrating roller pressure can break the original stress distribution on the tape surface, allowing the adhesive on the tape to penetrate and diffuse better, thereby effectively improving the adhesive strength of the tape and ensuring the accuracy of the bonding parameters.

[0033] In this embodiment of the invention, an auxiliary roller 50 may also be included. The auxiliary roller 50 is at the same height as the roller 201, and both sides of the auxiliary roller 50 are connected to the mounting frame 60 via connecting rods 501. In this embodiment, the auxiliary roller can first flatten the tape, preventing the tape from being too wrinkled and affecting the subsequent compaction of the tape by the roller 201.

[0034] In summary, the constant pressure adhesive tape bonding device of this utility model embodiment can vibrate and roll the adhesive tape through the roller pressing mechanism, which effectively overcomes the shortcomings of the existing design that relies on self-weight pressure, and significantly improves the adhesive force and accuracy of the adhesive tape.
