Description

Technical Field

[0001] This utility model relates to the field of RFID tag manufacturing technology, and in particular to an RFID tag lamination device. Background Technology

[0002] In the manufacturing process of RFID (Radio Frequency Identification) tags, lamination is an important production step. The principle is to laminate components such as chips and antennas together with the tag material.

[0003] In practice, the substrate material with assembled chips and antennas is stacked with the upper and lower packaging materials, such as plastic film and PVC (polyvinyl chloride) board. During the stacking, a tray is usually used for support and fixation. Then, a laminator is used to laminate the materials on the stacked tray. During the lamination process, high temperature and high pressure are used to make the materials of each layer tightly bonded.

[0004] However, since the trays are stacked in the heating and cooling chambers of the laminator, and each tray is located between the upper and lower corresponding extrusion plates, when the upper and lower corresponding extrusion plates are driven to move closer to each other and extrude the material on the tray by the hydraulic mechanism, the material on the tray may be misaligned due to uneven force, resulting in quality defects in the final RFID tag. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a lamination device for RFID tags. Before lamination in the laminator, the substrate material with assembled chips and antennas can be positioned and pre-pressed with the upper and lower packaging materials. During the process of moving to the laminator and during the lamination process, the position of the materials can be prevented from deviating.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a lamination device for RFID tags, including a base plate, a first surrounding plate, a floating block, and a cover plate. The first surrounding plate is disposed along the circumferential edge of the base plate, and the base plate and the first surrounding plate together form a pressing cavity. The floating block is disposed on the base plate and is located outside the pressing cavity. When the floating block is in the equilibrium position, its top is higher than the height of the first surrounding plate. One end of the cover plate opens or closes the top opening of the pressing cavity through a hinge structure. The cover plate is slidably limited to the top of the floating block. One end of the hinge structure is rotatably disposed on the first surrounding plate and elastically slidably disposed on the first surrounding plate. The other end of the hinge structure is connected to the floating block. The side of the cover plate facing the pressing cavity is provided with an extrusion plate that matches the pressing cavity.

[0008] Furthermore, the RFID tag laminating device also includes a second enclosure plate and a first spring. The second enclosure plate is disposed on the base plate, and the second enclosure plate and the first enclosure plate together form a floating cavity. The floating block is inserted into the floating cavity, and one end of the first spring is connected to the bottom of the floating cavity, and the floating block is connected to the other end of the first spring.

[0009] Furthermore, the first enclosure plate is provided with a first straight groove, and the hinge structure includes an arc plate and a rotating arm. The arc plate has an arc groove in the middle, one end of the arc plate is rotatably disposed in the first straight groove, and a second spring is provided between the arc plate and the side wall of the first straight groove. The other end of the arc plate is fixedly connected to the floating block, one end of the rotating arm is connected to the cover plate, and the other end of the rotating arm is slidably limited within the arc groove.

[0010] Furthermore, the top of the floating block is provided with an arc-shaped groove, and the side of the cover plate facing the pressing cavity is provided with an arc-shaped block that matches the arc-shaped groove.

[0011] Furthermore, both the arc-shaped plate and the rotating arm are located outside the pressing cavity, and the second enclosure plate is provided with a second straight groove communicating with the floating cavity. The arc-shaped plate is connected to the floating block through the second straight groove.

[0012] Furthermore, one end of the rotating arm is provided with a roller, which is confined within the arc-shaped groove.

[0013] Furthermore, the pressing cavity is stepped, and the extrusion plate includes a first pressure plate and a second pressure plate. The size of the first pressure plate is larger than the size of the small end of the pressing cavity, and the size of the first pressure plate is smaller than the size of the large end of the pressing cavity. The size of the second pressure plate is adapted to the size of the small end of the pressing cavity.

[0014] Furthermore, a height adjustment device is provided between the first pressure plate and the second pressure plate.

[0015] Furthermore, the pressing cavity is rectangular, and the height adjustment device includes multiple pins, which are rotatably connected to the first pressure plate and threadedly connected to the second pressure plate.

[0016] Furthermore, the cover plate is provided with a countersunk hole, and the first pressure plate is provided with a through hole. The countersunk hole and the through hole are concentrically arranged, and the pin is sequentially inserted into the countersunk hole and the through hole.

[0017] The beneficial effects of this invention include at least the following: by placing the substrate material of the assembled chip and antenna along with the upper and lower packaging materials in the pressing cavity, these materials can be precisely fixed in the vertical direction. Then, the opening at the top of the pressing cavity can be quickly closed by the flip-up cover, and the extrusion plate can be pressed against the material surface. In this way, during the process of moving the laminating device into the laminator, the material in the pressing cavity can be prevented from shifting position. At the same time, when the laminator is pressing, the cover and the floating block move downward synchronously, and the extrusion plate further extrudes the material in the pressing cavity. Since the extrusion plate is restricted radially by the pressing cavity, the radial movement of the material is small throughout the lamination process. Thus, the position of the material is not easily deviated, ensuring the lamination quality. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please refer to Figures 1 to 4 The present invention provides an RFID tag lamination device, comprising a base plate 100, a first enclosure plate 200, a floating block 300, and a cover plate 400.

[0029] Specifically, the first surrounding plate 200 is arranged along the circumferential edge of the base plate 100. The base plate 100 and the first surrounding plate 200 together form a pressing cavity 500. The pressing cavity 500 is used to place the substrate material and upper and lower packaging materials assembled with the chip and antenna. The top of the pressing cavity 500 is provided with an opening 510. The floating block 300 is arranged on the base plate 100 and is located outside the pressing cavity 500. When the floating block 300 is not squeezed by the laminator, it is in a balanced position. At this time, the top of the floating block 300 is higher than the height of the first surrounding plate 200. One end of the cover plate 400 opens or closes the opening 510 at the top of the pressing cavity 500 through the hinge structure 600. The sliding limit of the cover plate 400 is located at the top of the floating block 300. That is, when the cover plate 400 rotates, the end of the cover plate 400 slides on the floating block 300 and does not detach from the floating block 300. One end of the hinge structure 600 is rotatably arranged on the first surrounding plate 200, and the hinge structure The end of the hinge structure 600 is elastically slidably disposed on the first enclosure plate 200. The other end of the hinge structure 600 is connected to the floating block 300. The cover plate 400 is provided with a pressing plate 410 matching the pressing cavity 500 on the side facing the pressing cavity 500. When the cover plate 400 closes the pressing cavity 500, the pressing plate 410 presses against the material surface inside the pressing cavity 500. When the laminator continues to press the cover plate 400 downward, the end of the hinge structure 600 connected to the floating block 300 moves downward synchronously. At this time, the end of the hinge structure 600 connected to the first enclosure plate 200 is pulled to move horizontally to the side of the floating block 300 to avoid deformation of the hinge structure 600. When the pressing action of the laminator is removed, the end of the hinge structure 600 connected to the first enclosure plate 200 returns to the initial position under the elastic force. At the same time, the end of the hinge structure 600 connected to the floating block 300 is pulled upward until it returns to the position where the cover plate 400 closes the pressing cavity 500.

[0030] In this embodiment, by placing the substrate material of the assembled chip and antenna along with the upper and lower packaging materials inside the pressing cavity 500, these materials can be precisely fixed in the vertical direction. Then, the opening 510 at the top of the pressing cavity 500 can be quickly closed by the flip-up cover plate 400, and the extrusion plate 410 is pressed against the material surface. In this way, during the process of moving the laminating device into the laminator, the material in the pressing cavity 500 can be prevented from shifting position. At the same time, when the laminator is pressing, the cover plate 400 and the floating block 300 move downward synchronously, and the extrusion plate 410 further extrudes the material in the pressing cavity 500. Since the extrusion plate 410 is restricted radially by the pressing cavity 500, the radial movement of the material is small throughout the lamination process, so the position of the material is not easily deviated, thus ensuring the lamination quality.

[0031] It should be noted that when the cover plate 400 closes the opening 510, the position of the extrusion plate 410 and the position of the pressing cavity 500 should not interfere with each other. At this time, it is necessary to reasonably set the shape and size of the extrusion plate 410 and the pressing cavity 500.

[0032] In some alternative embodiments, such as Figures 1 to 3 As shown, the RFID tag lamination device also includes a second enclosure plate 700 and a first spring 800. The second enclosure plate 700 is disposed on the base plate 100, and the second enclosure plate 700 and the first enclosure plate 200 together form a floating cavity 900. A floating block 300 is inserted into the floating cavity 900, and the floating block 300 can slide up and down in the floating cavity 900. The lower end of the first spring 800 is fixedly connected to the bottom of the floating cavity 900, and the lower end of the floating block 300 is fixedly connected to the upper end of the first spring. In this embodiment, the floating block 300 is in a balanced position when it is not squeezed by the laminator. Specifically, the upward elastic force generated by the first spring 800 is equal to the weight of the floating block 300. When the floating block 300 is squeezed by the laminator, the floating block 300 slides downward in the floating cavity 900. When the laminator is not squeezing, the floating block 300 slides upward in the floating cavity 900 until it returns to the balanced position.

[0033] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the first enclosure plate 200 is provided with a first straight groove 210, and the hinge structure 600 includes an arc plate 610 and a rotating arm 620. Specifically, the arc plate 610 is provided with an arc groove 611 in the middle, the right end of the arc plate 610 is rotatably disposed in the first straight groove 210, a second spring 630 is provided between the right end of the arc plate 610 and the side wall of the first straight groove 210, the left end of the arc plate 610 is fixedly connected to the floating block 300, the upper end of the rotating arm 620 is fixedly connected to the end of the cover plate, the lower end of the rotating arm 620 is slidably disposed in the arc groove 611, and the lower end of the rotating arm 620 does not detach from the arc groove 611 during the sliding process.

[0034] In this embodiment, when the cover plate 400 rotates and the opening 510 is not closed, the floating block 300 is always in a balanced position under the elastic action of the first spring 800, and the right end of the arc plate 610 is always in a balanced position under the elastic action of the second spring 630. At this time, the upper end of the rotating arm 620 remains stable until the right end of the rotating arm 620 slides from the right end of the arc groove 611 to the left end of the arc groove 611, at which point the cover plate 400 just closes the opening 510. When the laminator presses down on the cover plate 400, the floating block 300 drives the upper end of the rotating arm 620 and the left end of the arc plate 610 to move downward. At this time, the left end of the arc plate 610 pulls the right end of the arc plate 610 to the left, and the right end of the arc plate 610 moves to the left within the first straight groove 210, causing the second spring 630 to stretch to the left, thereby keeping the distance between the left and right ends of the arc plate 610 unchanged and ensuring that the arc plate 610 will not be damaged due to deformation. When the laminator is not pressing, the floating block 300 slides upward in the floating cavity 900 until it returns to the equilibrium position. At this time, under the elastic force of the first spring 800 and the second spring 630, both the left and right ends of the arc plate 610 return to the position where the cover plate 400 covers the opening 510 at the top of the pressing cavity 500.

[0035] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the top of the floating block 300 is provided with an arc-shaped groove 310, and the cover plate 400 is provided with an arc-shaped block 520 that matches the arc-shaped groove 310 on the side facing the pressing cavity 500. The arc-shaped groove 310 limits the arc-shaped block 520 to prevent the cover plate 400 from deviating from its position when rotating.

[0036] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the arc plate 610 and the rotating arm 620 are both located outside the pressing cavity 500, and the second enclosure plate 700 is provided with a second straight groove 710 that communicates with the floating cavity 900. The arc plate 610 is connected to the floating block 300 through the second straight groove 710. In this way, when the laminator presses the cover plate 400 downward, the floating block 300 can smoothly drive the upper end of the rotating arm 620 and the left end of the arc plate 610 to move downward.

[0037] In order to allow the lower end of the swing arm 620 to slide smoothly within the arc-shaped groove 611, in some optional embodiments, such as Figure 1 , Figure 2 As shown, one end of the rotating arm 620 is provided with a roller 621, and the roller 621 is confined within the arc-shaped groove 611. For example, the middle dimension of the roller 621 can be adapted to the width of the arc-shaped groove 611, while the middle dimension of the roller 621 is smaller than the dimensions of the two ends of the roller 621.

[0038] When the cover plate 400 closes the opening 510, in order to prevent the position of the pressing plate 410 from interfering with the position of the pressing cavity 500, in some optional embodiments, such as Figure 3 As shown, the pressing cavity 500 is stepped, with the larger end at the top and the smaller end at the bottom. The pressing plate 410 includes a first pressing plate 411 and a second pressing plate 412. The size of the first pressing plate 411 is larger than the size of the smaller end of the pressing cavity 500, and the size of the first pressing plate 411 is smaller than the size of the larger end of the pressing cavity 500. The size of the second pressing plate 412 is equal to the size of the smaller end of the pressing cavity 500. When the cover plate 400 just covers the opening 510, the lower surface of the second pressing plate 412 does not extend into the smaller end of the pressing cavity 500.

[0039] In some alternative embodiments, such as Figure 3 As shown, a height adjustment device 420 is provided between the first pressure plate 411 and the second pressure plate 412. By providing the height adjustment device 420, the position of the second pressure plate 412 relative to the first pressure plate 411 can be adjusted so that when the cover plate 400 closes the opening 510, it can press against materials of different heights placed in the small end of the pressing cavity 500.

[0040] In some alternative embodiments, such as Figure 3 As shown, the pressing cavity 500 is rectangular, and the height adjustment device 420 includes multiple pins. The pins are rotatably connected to the first pressing plate 411 and threadedly connected to the second pressing plate 412. The position of the second pressing plate 412 relative to the first pressing plate 411 can be adjusted by rotating the pins in both directions.

[0041] To facilitate the adjustment of the pin on the outside of the cover plate 400, in some optional embodiments, such as Figure 3 , Figure 4 As shown, the cover plate 400 is provided with a countersunk hole 430, and the first pressure plate 411 is provided with a through hole 4111. The countersunk hole 430 and the through hole 4111 are concentrically arranged. The pin passes through the countersunk hole 430 and the through hole 4111 in sequence and is then threadedly connected to the second pressure plate 412.
