TECHNICAL FIELD
[0001] The utility model relates to the technical field of adhesive tape die cutting equipment, specifically to a die cutting device of VHB foam tape. BACKGROUND
[0002] In the field of modern industrial manufacturing and building decoration, VHB foam tape occupies an important position due to its unique performance advantages. In the electronic manufacturing industry, as the integration of equipment continues to improve, the connection precision and stability between parts are highly required. The high adhesion of VHB foam tape can achieve firm bonding of precision electronic components, and the strong buffering performance can effectively resist vibration and impact during transportation, protecting fragile core components such as chips and circuit boards.
[0003] After searching, the publication number is CI109761077A, a die cutting process of VHB foam tape, including the following steps: S1: the non-release surface of the first release film is attached to the bottom film, the release paper on the low-adhesion surface of the first double-sided adhesive tape is wound, and the low-adhesion surface is attached to the release surface of the first release film; S2: the film-free surface of the foam is attached to the high-adhesion surface of the first double-sided adhesive tape, then the protective film on the other surface of the foam is wound, the high-adhesion surface of the second double-sided adhesive tape is attached to the surface, then the release paper on the low-adhesion surface of the second double-sided adhesive tape is wound, and the second release film is attached to the low-adhesion surface of the second double-sided adhesive tape to obtain a composite layer; S3: the composite layer is cut to the bottom film by a cutter to obtain an L-shaped foam tape; the cut waste material frame is wound and removed by a waste roller, and the bottom film is pulled and wound by an output roller to separate the foam tape from the bottom film and enter the storage box. The die cutting process of VHB foam tape can realize gapless layout, save materials, and reduce production cost.

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.
[0028] Please refer to Figures 1-4 The present application is a die cutting device of VHB foam tape, which comprises:
[0029] The support component comprises an equipment rack 100;
[0030] The anti-static component comprises an anti-static bar 200, a fixing block 201, a supporting column 202, a positioning hole 203, a clamping ring 204 and a positioning rod 205, the fixing block 201 is installed on the upper portion of the equipment rack 100, the supporting column 202 is fixed on the outer surface of the anti-static bar 200 at both ends, the clamping ring 204 is fixed on one end of the fixing block 201 and clamped and connected on the outer surface of the supporting column 202 at both ends, the positioning hole 203 is arranged in the inner portion of the supporting column 202 and the clamping ring 204, and the positioning rod 205 is inserted and connected in the inner portion of the positioning hole 203.
[0031] The supporting column 202 is inlaid between the two clamping rings 204, and the cooperation of the positioning rod 205 and the positioning hole 203 ensures that the anti-static bar 200 is firmly installed on the upper portion of the inner surface of the equipment rack 100, the anti-static bar 200 is distributed on the upper portion and the lower portion of the adhesive tape, and a three-dimensional static elimination field is formed, when the adhesive tape is conveyed in the equipment, the upper and lower surfaces of the adhesive tape are simultaneously subjected to the action of positive and negative ions released by the anti-static bar 200, and the static electricity on the surface of the adhesive tape can be more completely eliminated.
[0032] The anti-static bar 200 is located on the upper portion of the inner surface of the equipment rack 100 and is in a symmetrical distribution form.
[0033] The outer surface of the positioning rod 205 is adhesively connected with a rubber ring 206, and the rubber ring 206 is extruded on both ends of the outer surface of the clamping ring 204.
[0034] When the positioning rod 205 is inserted into the inner portion of the positioning hole 203, the rubber ring 206 at one end can be extruded, so that the rubber ring 206 penetrates the inner portion of the positioning hole 203 and is finally limited on both ends of the clamping ring 204 to limit the positioning rod 205.
[0035] The outer surface of the positioning rod 205 is threadedly connected with a fastening ring 207, and the fastening ring 207 is wrapped on the outer surface of the rubber ring 206.
[0036] The fastening ring 207 is fixed by being extruded on the outer portion of the rubber ring 206.
[0037] The supporting component further comprises a winding roller 101, a die-cutting roller 102 and a supporting plate 103, the winding roller 101 is fixed on one end of the inner surface of the equipment rack 100, the die-cutting roller 102 is fixed on the upper portion of the other end of the equipment rack 100, and the supporting plate 103 is arranged at both ends of the die-cutting roller 102.
[0038] The working principle is that first, the supporting column 202 is embedded between the two clamping rings 204 to form a stable base frame. When the positioning rod 205 is inserted into the positioning hole 203, it will exert a pressing force on the rubber ring 206. The rubber ring 206 has good elasticity and plasticity, and will deform after being stressed, gradually penetrating the positioning hole 203 and extending to both ends of the clamping ring 204, limiting the positioning rod 205 from the axial direction. By rotating the fastening ring 207, the outer side of the rubber ring 206 is subjected to radial pressure by the internal threaded structure. After being subjected to axial and radial extrusion, the rubber ring 206 tightly fits the positioning rod 205 and the clamping ring 204, forming a firm connection. In the adhesive tape cutting process, the winding roller 101 and the die cutting roller 102 operate in coordination to drive the adhesive tape through the equipment working area at a constant speed. The anti-static bars 200 distributed on the upper and lower parts of the adhesive tape can quickly and comprehensively neutralize the static charge generated on the surface of the adhesive tape when the adhesive tape with static electricity enters the field. This can more thoroughly eliminate the static electricity on the surface of the adhesive tape, and the dust-free adhesive tape surface is smoother, ensuring the adhesion and fitting performance of the adhesive tape.
[0039] Please refer to Figure 1 、 Figure 2 The embodiment further includes:
[0040] The guide component includes a guide rod 300, a guide ring 302, and a limiting disc 301. The guide rod 300 is fixed to the inner surface of the equipment frame, the guide ring 302 is movably connected to the outside of the guide rod 300, the fixed block 201 is fixed to one end of the guide ring 302, and the limiting disc 301 is fixed to the top of the guide rod 300.
[0041] The height of the anti-static bar 200 can be adjusted by moving the guide ring 302 up and down on the outside of the guide rod 300.
[0042] The other end of the outer surface of the guide ring 302 is fixed with an internal threaded ring 303, the middle part of the internal threaded ring 303 is threadedly connected with a threaded rod 304, and the outer end of the threaded rod 304 is rotatably connected with a handle 305.
[0043] Rotating the handle 305 drives the threaded rod 304 to rotate, so that the threaded rod 304 clamps the outside of the guide rod 300, and fixes the adjusted height of the anti-static bar 200.
[0044] The working principle is that the inner surface of the guide ring 302 is closely attached to the outer surface of the guide rod 300, while a certain movement allowance is reserved, so that the guide ring 302 can stably slide up and down along the guide rod 300, thereby driving the anti-static bar 200 fixed on the guide ring 302 to move synchronously. In the adhesive tape die-cutting operation, the operator can flexibly adjust the height of the anti-static bar 200 according to the actual production needs. When the adhesive tape conveying position changes, the anti-static bar 200 can be quickly adjusted to a position that maintains the optimal distance from the adhesive tape surface by manually pushing the guide ring 302, so as to ensure that the ions generated by the anti-static bar 200 can efficiently neutralize the static electricity on the adhesive tape surface. After the height adjustment is completed, the threaded rod 304 is rotated by rotating the handle 305, the threaded rod 304 and the guide ring 302 are connected in a threaded manner, and finally clamped outside the guide rod 300. With the threaded rod 304 being continuously tightened, a strong friction force is generated between the threaded rod 304 and the guide rod 300, and the friction force is sufficient to limit the movement of the guide ring 302 on the guide rod 300, so as to fix the anti-static bar 200 at the adjusted height position and maintain a stable static electricity elimination effect.
