Description

Technical Field

[0001] This utility model relates to the field of radio frequency identification tag manufacturing technology, and in particular to a tag adhesive level adjustment mechanism. Background Technology

[0002] Electronic tags (such as RFID tags), also known as radio frequency tags, are core components for item identification and data carriers, and their applications cover multiple fields such as logistics warehousing, industrial production, and asset management. In the production process of electronic tags, the master material (sheet material printed with electronic modules) needs to be laminated into the tag paper. During lamination, adhesive needs to be applied between the electronic module sheet material and the tag paper to ensure the structural stability of the electronic tag.

[0003] However, existing technologies lack precise control over the adhesive application process. When applying adhesive to the masterbatch of electronic tags, the adhesive outlet of the applicator is not parallel to the material, resulting in uneven adhesive layer thickness. This is further exacerbated when producing wide products or manufacturing multiple rows simultaneously, leading to inconsistent adhesive application. If the horizontal relationship of the adhesive outlet needs to be changed, existing technologies typically adjust the locking end of the applicator according to the locking position. However, this adjustment process is difficult to control precisely, and repeated adjustments can cause the locking mechanism to deform and loosen.

[0004] Therefore, there is a need for a label adhesive level adjustment mechanism that is simple in structure and allows for precise control. Utility Model Content

[0029] like Figures 1-5 As shown, this utility model proposes a label adhesive level adjustment mechanism 1000, applied to an adhesive application mechanism 2000, comprising: a fixed plate 100; a sliding assembly 200, the sliding assembly 200 including an arc-shaped guide rail 210, a slider 220, and a movable plate 230, the arc-shaped guide rail 210 being fixedly disposed on the top surface of the fixed plate 100, the arc center of the arc-shaped guide rail 210 coinciding with the geometric center axis of the fixed plate 100, the slider 220 being slidably connected to the arc-shaped guide rail, the movable plate 230 being fixedly disposed on the top of the slider 220 by bolts, and the adhesive application mechanism 2000 being fixedly disposed on the top of the movable plate 230; and an adjustment assembly 300, the adjustment assembly 300 including a micrometer. The micrometer 310 includes a base portion 321 and two vertical arms 322. The base portion 321 is disposed on the fixed plate 100 near the arc-shaped guide rail 210. The two vertical arms 322 are fixedly disposed at both ends of the base portion 321 and extend along both ends of the base portion 321 away from the arc-shaped guide rail 210. The micrometer 310 includes an input end 311 and an output end 312. The input end 311 and the output end 312 are screwed together. The vertical arms 322 are provided with through holes corresponding to the input end 311. The input end 311 is rotatably mounted on the inner wall of the through hole. The output end 312 is fixedly connected to the movable plate 230.

[0030] Understandably, when applying adhesive to the masterbatch of electronic tags, if the adhesive outlet of the applying device is not parallel to the masterbatch, it will lead to problems such as uneven adhesive layer thickness and inconsistent adhesive amount. Therefore, during the adhesive application process of the applying device 2000 relative to the electronic tag masterbatch, it is necessary to ensure that the adhesive outlet of the applying device 2000 is parallel to the masterbatch. To ensure parallelism, the angle of the adhesive outlet of the applying device 2000 needs to be precisely adjusted.

[0031] In this embodiment, the fixing plate 100 is bolted to an external working base. The top surface of the fixing plate 100 has positioning holes. The arc-shaped guide rail 210 in the sliding assembly 200 is fixedly connected to the fixing plate 100 via countersunk screws, corresponding to the positioning holes. The arc center of the arc-shaped guide rail 210 is located on the vertical line of the geometric center of the fixing plate 100. The bottom of the slider 220 has an arc-shaped groove corresponding to the arc-shaped guide rail. The slider 220 forms a sliding pair with the arc-shaped guide rail through the arc-shaped groove. The movable plate 230 is fixedly mounted on the top surface of the slider 220 via countersunk screws. In the U-shaped structure of the mounting bracket 320, the base portion 321 is welded to the right side of the fixing plate 100 (as shown in the image). Figure 1 Taking the direction shown as an example, the two upright arms 322 extend upwards perpendicular to the base 321 to form the support arms of the micrometer 310. The input end 311 of the micrometer 310 passes through a through hole opened on the upright arm 322, and the output end 312 of the micrometer 310 is connected to the movable plate 230. It can be understood that a ball bearing or other support component can be provided in the through hole to ensure that the axis of the micrometer 310 coincides with the axis of the through hole. In this embodiment, the arc-shaped guide rail 210 coincides with the central axis of the fixed plate 100 to ensure that the glue application mechanism 2000 rotates around the geometric center of the fixed plate 100 to achieve precise angle adjustment and avoid the influence of eccentric torque. At the same time, the movable plate 230 and the slider 220 are directly connected by bolts, which allows the operator to quickly disassemble and replace them to adapt to glue application mechanisms 2000 of different sizes.

[0032] In another embodiment, the base portion 321 is provided with a threaded hole on the peripheral side of the fixing plate 100, and the base portion 321 is fixedly disposed on the peripheral side of the fixing plate 100 by countersunk screws.

[0033] In one embodiment, the arc-shaped guide rail 210 includes a first guide rail 211 and a second guide rail 212. The first guide rail 211 and the second guide rail 212 are fixedly disposed on the top of the fixed plate 100. The number of sliders 220 is two, corresponding to the first guide rail 211 and the second guide rail 212. The two sliders 220 are slidably connected to the first guide rail 211 and the second guide rail 212 respectively. The first guide rail 211 is disposed on the side of the fixed plate 100 near the adjustment component 300. The first guide rail 211 and the second guide rail 212 are symmetrically arranged, and the arc centers of the first guide rail 211 and the second guide rail 212 coincide at the same point.

[0034] In this embodiment, the first guide rail 211 and the second guide rail 212 are symmetrically distributed on both sides of the central axis of the fixed plate 100. The distance between the first guide rail 211 and the second guide rail 212 can be adjusted according to the mass of the movable plate 230 and the glue application mechanism 2000. The cross-sections of the first guide rail 211 and the second guide rail 212 are both I-shaped. The arc-shaped groove at the bottom of the slider 220 is set to correspond to the cross-section of the guide rail. The first guide rail 211 and the second guide rail 212 are symmetrically arranged to form a stable support surface to bear the working load generated by the movable plate 230 during movement.

[0035] In one embodiment, the sliding assembly 200 further includes a traction plate 240, which includes a horizontal connecting plate 241 and a vertical connecting plate 242. The horizontal connecting plate 241 and the vertical connecting plate 242 are vertically connected. The horizontal connecting plate 241 is fixedly connected to the bottom end of the movable plate 230 and extends along the width direction of the movable plate 230. The horizontal connecting plate 241 is spaced apart from the first guide rail 211. The vertical connecting plate 242 is disposed on the side of the horizontal connecting plate 241 near the adjusting assembly 300. The vertical connecting plate 242 is provided with a through hole, and the output end 312 of the micrometer 310 is connected to the vertical connecting plate 242 through the through hole.

[0036] In this embodiment, the traction plate 240 has a T-shaped structure. The horizontal connecting plate 241 is fixedly connected to the right side of the movable plate 230. The vertical connecting plate 242 extends upward perpendicular to the extension direction of the horizontal connecting plate 241. The vertical connecting plate 242 has a through hole, which is coaxially arranged with the micrometer 310. The inner wall of the through hole abuts against the output end 312 of the micrometer 310. By rotating the input end 311 of the micrometer 310, the operator pushes the output end 312 of the micrometer 310 to move. The output end 312 then distributes the thrust of the micrometer 310 evenly to the movable plate 230 through the traction plate 240, so that the glue application mechanism 2000 fixedly set at the top of the movable plate 230 can accurately transfer angles. It is understood that a gap is maintained between the horizontal connecting plate 241 and the first guide rail 211 to avoid motion interference.

[0037] In another embodiment, the output end 312 of the micrometer 310 is machined with external threads, the inner wall of the through hole can be fitted with a threaded sleeve, and anti-loosening nuts are provided on both sides of the through hole to strengthen the connection rigidity between the micrometer 310 and the traction plate 240.

[0038] In one embodiment, the slider 220 includes an arc-shaped block 221. The bottom end of the arc-shaped block 221 is provided with an arc-shaped groove corresponding to the arc-shaped guide rail 210. The arc-shaped guide rail 210 is slidably connected to the arc-shaped groove. The two sides of the arc-shaped block 221 are provided with arc-shaped surfaces corresponding to the arc segments of the arc-shaped guide rail 210. The top surface of the arc-shaped block 221 abuts against the movable plate 230. The movable plate 230 is slidably connected to the fixed plate 100 through the arc-shaped block 221.

[0039] In this embodiment, two arc-shaped blocks 221 are provided corresponding to the first guide rail 211 and the second guide rail 212. The two arc-shaped blocks 221 are symmetrically arranged, and the arc-shaped grooves opened at the bottom of the arc-shaped blocks 221 form an automatic centering structure with the first guide rail 211 or the second guide rail 212. It can be understood that during assembly, a grease including but not limited to molybdenum disulfide is first applied, and a lubricating oil film storage space is formed by the curvature difference design before pressing into the guide rail to extend the service life.

[0040] In one embodiment, the slider 220 is further provided with connecting ears 222. There are two connecting ears 222. The two connecting ears 222 are respectively fixedly connected to the two arc surfaces of the arc block 221, and the top surface of the two connecting ears 222 is on the same plane as the top surface of the arc block 221. The connecting ears 222 are provided with threaded holes, and the connecting ears 222 are threadedly connected to the movable plate 230 by bolts.

[0041] In this embodiment, the connecting lug 222 is welded to the two arc-shaped surfaces of the arc-shaped block 221. The connecting lug 222 is inverted L-shaped and extends upward along the bottom of the arc-shaped surface of the arc-shaped block 221 and then to both sides of the arc-shaped block 221. The top surface of the connecting lug 222 is on the same plane as the top surface of the arc-shaped block 221, and this plane is used to support the movable plate 230. The connecting lug 222 has a connecting hole, and the movable plate 230 also has a through hole corresponding to the connecting hole. After a bolt passes through the through hole and the connecting hole from top to bottom, the movable plate 230 is bolted to the arc-shaped block 221.

[0042] In one embodiment, the adjustment assembly 300 further includes a limiting member 330, which is sleeved on the end of the output end 312 and threadedly connected to the output end 312. The diameter of the limiting member 330 is larger than the inner diameter of the through hole on the upright arm portion 322.

[0043] It is understood that the limiting member 330 is located at the end of the output end 312 and the limiting member 330 is detachably connected to the output end 312. In this embodiment, the limiting member 330 and the output end 312 are threaded together, and the end of the output end 312 is provided with a threaded section. During the installation process, after the output end 312 passes through the vertical connecting plate 242 and the upright arm 322, the operator screws the limiting member 330 onto the end of the output end 312. The diameter of the limiting member 330 is larger than the inner diameter of the through hole of the upright arm 322, thereby preventing the micrometer 310 from accidentally coming out.

[0044] In one embodiment, the label adhesive level adjustment mechanism 1000 further includes an adhesive baffle 400, which has a U-shaped structure. The adhesive baffle 400 is disposed on the fixed plate 100 on the side facing the adhesive outlet of the adhesive applicator 2000, and the bottom surface of the adhesive baffle 400 is fixedly connected to the fixed plate 100.

[0045] In this embodiment, the adhesive baffle 400 adopts a U-shaped structure. After the adhesive baffle 400 is installed, the top end of the adhesive baffle 400 is threadedly connected to the bottom end of the movable plate 230, and the bottom end of the adhesive baffle 400 is threadedly connected to the bottom end of the fixed plate 100. The adhesive baffle 400 is used to prevent the adhesive dripping from the glue outlet of the glue applicator 2000 from entering the interior and causing damage to the equipment. At the same time, it can also recycle the residual adhesive that adheres to the adhesive baffle 400 after cooling, thereby improving the utilization rate of the adhesive and the service life of the equipment.

[0046] This invention features an arc-shaped guide rail symmetrically arranged with a first guide rail and a second guide rail on a fixed plate, along with corresponding arc-shaped blocks. Connecting ears are provided on both sides of the arc-shaped blocks, and a movable plate is fixedly connected to it via these connecting ears. The movable plate is supported by the connecting ears and the top surface of the arc-shaped blocks. The output end of a micrometer pushes the movable plate to complete the drive. By converting the elongation of the micrometer in the adjustment assembly into the rotational stroke of the movable plate, the rotational displacement of the movable plate relative to the fixed plate can be precisely controlled. Furthermore, the gluing mechanism fixed to the top of the movable plate can be precisely controlled relative to the angle of the electronic tag masterbatch. This invention has the advantages of simple structure and improved production efficiency.
