Description

Technical Field

[0001] This utility model belongs to the field of RFID processing technology, and specifically relates to an adhesive coating device for RFID tags. Background Technology

[0002] RFID is a radio frequency identification technology, and electronic tags are usually used as the carrier of RFID technology. Therefore, RFID is often used to refer to electronic tags. Electronic tags are also called radio frequency tags, transponders, and data carriers. Electronic tags and readers achieve spatial (contactless) coupling of radio frequency signals through coupling elements. Within the coupling channel, energy transfer and data exchange are realized according to timing relationships. The coating process of electronic tags requires the use of positioning devices.

[0003] Existing electronic tag spraying and positioning mechanisms can generally only spray paper or plastic products of the same thickness. However, in actual production, there is often a need to produce electronic tags of different thicknesses. Therefore, it is necessary to equip the equipment with spraying equipment of various specifications that can use electronic tags of different thicknesses, which indirectly increases production costs.

[0004] In existing technologies, although spray positioning mechanisms exist, they employ pressure cylinders on the roll and raw material rollers, with movable blocks and pressure rods on either side of the pressure cylinders. The pressure rods move the movable blocks within a chute, adjusting the height of the pressure cylinder and thus the distance between it and the roll or raw material rollers is adjustable. The movable blocks are then fixed in place by external fasteners, accommodating electronic tags of varying thicknesses. However, this device requires manual adjustment of the pressing distance based on experience. To ensure proper adjustment, repeated adjustments are necessary. Furthermore, since adjustments must be made separately on both sides of the pressure cylinder, and their heights must be consistent, the adjustment time is longer, making the operation cumbersome and impacting production efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an RFID tag coating device, which aims to solve the problem that the existing RFID tag spraying and positioning device needs to adjust the height of the pressure cylinder to adapt to electronic tags of different thicknesses, but the adjustment of the pressure cylinder height is cumbersome and affects production efficiency.

[0006] The RFID tag coating device proposed in this utility model includes a roll assembly and a discharge assembly arranged in parallel, and a spraying assembly disposed between the roll assembly and the discharge assembly. The roll assembly includes a mounting base and a roll roller and a first pressing roller disposed in the mounting base. The mounting base includes two vertically arranged parallel sections and a horizontal section connecting the two vertical sections, as well as a reciprocating lead screw and a slider sleeved on the reciprocating lead screw disposed in the vertical section. The vertical section is provided with a groove adapted to the slider, and the groove is used to accommodate the reciprocating lead screw and the slider. The inner side of the vertical section is provided with a clearance groove communicating with the groove. The discharge assembly includes the mounting base, a discharge roller and a second pressing roller. Both ends of the first pressing roller and the second pressing roller are respectively connected to the slider through the clearance groove.

[0007] The aforementioned RFID tag coating device achieves normal roll-to-roll coating of electronic tags through a roll assembly, a discharge assembly, and a spraying assembly. A mounting base and a reciprocating screw within the vertical section of the mounting base connect the first and second pressure rollers to sliders on the reciprocating screw. This allows for height adjustment of the first and second pressure rollers by rotating the reciprocating screw, which moves the sliders up and down along the screw. Furthermore, the threaded drive between the reciprocating screw and the sliders ensures consistent slider movement by rotating the screw the same number of times on both sides, and allows for precise determination of slider movement distance by rotating it a different number of times. This significantly improves the efficiency of adjusting the height of the first and second pressure rollers. Therefore, this invention solves the problem in existing RFID tag coating and positioning devices that require adjusting the pressure cylinder height to accommodate electronic tags of different thicknesses, which is cumbersome and affects production efficiency.

[0027] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0028] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] 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.

[0031] Please see Figures 1 to 6 The image shows an RFID tag coating device according to an embodiment of the present invention, comprising a roll assembly 10 and a discharge assembly 20 arranged in parallel, and a spraying assembly 30 disposed between the roll assembly 10 and the discharge assembly 20, wherein:

[0032] The coil assembly 10 includes a mounting base 11 and a coil roller 12 and a first pressing roller 13 disposed within the mounting base 11. The mounting base 11 includes two parallel vertical portions 111 and a horizontal portion 112 connecting the two vertical portions 111, as well as a reciprocating lead screw 14 disposed within the vertical portions 111 and a slider 15 sleeved on the reciprocating lead screw 14. The vertical portions 111 are provided with a groove 16 adapted to the slider 15. The groove 16 is used to accommodate the reciprocating lead screw 14 and the slider 15. The inner side of the vertical portions 111 is provided with a clearance groove 17 communicating with the groove 16. The discharge assembly 20 includes a mounting base 11, a discharge roller 21 and a second pressing roller 22. Both ends of the first pressing roller 13 and the second pressing roller 22 are respectively connected to the slider 15 through the clearance groove 17.

[0033] Understandably, the roll material assembly 10, the discharge assembly 20, and the spraying assembly 30 enable the normal roll material spraying process for electronic tags. Furthermore, by setting up the mounting base 11 and the reciprocating screw 14 located within the vertical portion 111 of the mounting base 11, both ends of the first pressing roller 13 and the second pressing roller 22 are connected to sliders 15 on the reciprocating screw 14. This allows for height adjustment of the first pressing roller 13 and the second pressing roller 22 by rotating the reciprocating screw 14, which in turn moves the sliders 15 up and down along the screw 14. Moreover, since the reciprocating screw 14 and the sliders 15 are connected by a threaded transmission, rotating the reciprocating screw 14 on both sides by the same number of turns ensures that the sliders 15 move the same distance on both screws 14. Rotating different numbers of turns accurately determines the movement distance of the sliders 15, thus greatly improving the efficiency of adjusting the height of the first pressing roller 13 and the second pressing roller 22. Therefore, this utility model solves the problem that the existing RFID tag spraying positioning device needs to adjust the height of the pressure cylinder to adapt to electronic tags of different thicknesses, but the adjustment of the pressure cylinder height is cumbersome and affects production efficiency.

[0034] It should be noted that the first pressing roller 13 and the second pressing roller 22 have connecting parts extending outward at both ends. These connecting parts are fixedly connected to the slider 15. The main bodies of the first pressing roller 13 and the second pressing roller 22 can rotate relative to the connecting parts, thereby ensuring that the height of the two sides of the first pressing roller 13 and the second pressing roller 22 is adjusted only by the movement of the slider 15 on the reciprocating screw 14, without restricting the rotation function of the two rollers themselves.

[0035] As an example, and not a limitation, in some alternative embodiments, a rotating shaft 18 is provided within the horizontal section 112, with first bevel gears 181 at both ends of the rotating shaft 18, and a second bevel gear 141 adapted to the first bevel gears 181 at the bottom of the reciprocating screw 14. By using the hollow design of the horizontal section 112 and the rotating shaft 18 therein, the reciprocating screws 14 on both sides are linked through the engagement of the first bevel gears 181 at both ends of the rotating shaft 18 and the second bevel gear 141 at the bottom of the reciprocating screw 14. This achieves linkage between the two reciprocating screws 14, meaning that rotating one reciprocating screw 14 can drive both reciprocating screws 14 to rotate synchronously with the same number of rotations. This allows for simultaneous adjustment of the height of both ends of the first lower pressure roller 13 or the second lower pressure roller 22, ensuring consistency in height at both ends, greatly simplifying the process of adjusting the pressure cylinder height and improving production efficiency.

[0036] Additionally, a drive unit 40 is provided on one side of the mounting base 11. The drive unit 40 is used to drive the rotating shaft 18 and the roll roller 12 to rotate respectively. In specific implementations, the drive unit 40 can drive the rotating shaft 18 and the roll roller 12 to achieve automated electronic tag spraying and winding, as well as automated adjustment of the height of the first pressure roller 13 or the second pressure roller 22, allowing the adhesive applicator to quickly adapt to products of different thicknesses. In specific implementations, the drive unit 40 can be a motor, with the drive shaft on the motor connected to the rotating shaft 18 and the roll roller 12 respectively via a connector to achieve the driving function. In specific implementations, multiple motors can be set up and controlled separately as needed. More specifically, the motor can be a stepper motor, a servo motor, or an asynchronous motor, etc.

[0037] Specifically, the drive component 40 includes a drive shaft 41 for connecting the motor and a first belt drive pulley 42 and a second belt drive pulley 43 disposed on the drive shaft 41. Both the rotating shaft 18 and the winding drum 12 are provided with belt driven pulleys 44 on the side near the drive component 40. The first belt drive pulley 42 is connected to the belt driven pulley 44 on the rotating shaft 18 through a belt 45, and the second belt drive pulley 43 is connected to the belt driven pulley 44 on the winding drum 12 through a belt 45. A one-way bearing 46 is provided between the first belt drive pulley 42 and the drive shaft 41. Specifically, by setting pulleys and belt 45, the drive unit 40 can drive the rotating shaft 18 or the winding drum 12 to rotate. Furthermore, in a specific implementation, by setting a one-way bearing 46, a single motor can simultaneously achieve drum height adjustment and material winding functions. That is, when the drive shaft 41 rotates to one side, the rotating shaft 18 and the winding drum 12 will rotate, at which time the height of the first pressing drum 13 can be adjusted. When rotating to the other side, due to the action of the one-way bearing 46, the rotating shaft 18 will not rotate, but the winding drum 12 will rotate to wind up the material. In addition, it should be noted that since the discharge drum 21 in the discharge assembly 20 is a driven component, the drive unit 40 located in the discharge assembly 20 only needs to drive the rotating shaft 18 to rotate, and therefore can be directly connected to one end of the rotating shaft 18.

[0038] Additionally, the drive unit 40 is a dual-axis motor, with its two drive shafts used to drive the coil roller 12 and the rotating shaft 18 to rotate, respectively. Furthermore, in specific implementations, a dual-axis motor can also be used. A dual-axis motor controlled independently by its two drive shafts can achieve the effect of a single motor drive without requiring additional complex transmission components. However, this requires a reasonable adjustment of the internal structural distribution and a larger installation space.

[0039] Specifically, a drying component 50 is provided between the spraying component 30 and the roll material component 10. The drying component 50 is used to dry the sprayed electronic tags. In practical implementation, by setting the drying component 50, the sprayed electronic tags can be dried quickly, thereby avoiding the need for a long winding distance required for natural cooling of the electronic tags, which would affect work efficiency. In addition, rapid drying can also effectively ensure the spraying effect, allowing the image to solidify and form quickly, avoiding excessive curing time and image distortion.

[0040] Furthermore, the roll assembly 10, the discharge assembly 20, the spraying assembly 30, and the drying assembly 50 are all mounted on independent base plates 60, allowing for adjustable relative positions among them. The independent base plates 60 enable adjustment of the relative positions of each component, allowing the adhesive application device to adapt to different workspaces or scenarios. Additionally, the relative height adjustment range between the roll assembly 10 and the discharge assembly 20 is greater, thus accommodating electronic label spraying requirements at greater tilt angles.

[0041] Specifically, the spraying assembly 30 includes a first top plate 31 disposed above the base plate 60, a connecting plate 32 for connecting the first top plate 31 and the base plate 60, a telescopic member 33 disposed on the top plate, and a spraying member 34 connected to the telescopic member 33. In specific implementation, the spraying height can be adjusted by connecting the telescopic member 33 to the spraying member 34, thereby adjusting the spraying effect according to requirements.

[0042] Additionally, the drying assembly 50 includes a second top plate 51 disposed above the base plate 60, a vertical plate 52 for connecting the second top plate 51 and the base plate 60, and a fan 53 disposed on the second top plate 51. In specific implementations, the fan 53 can be used to quickly dry and cool the electronic label after spraying, thereby achieving the effect of rapid pattern curing.

[0043] As an example, and not a limitation, in some alternative embodiments, one end of the reciprocating screw 14 extends beyond the top of the vertical portion 111 and is equipped with a knob 142. Rotating the knob 142 adjusts the height of one side of the first pressure roller 13 or the second pressure roller 22. Furthermore, the rotation of the reciprocating screw 14 can be controlled by the knob 142, instead of by the drive component 40. This method is suitable for users with relatively stable electronic tag thickness, eliminating the need for frequent adjustments to the adhesive application device and reducing the drive component 40, thus effectively lowering the cost of the adhesive application device.

[0044] In summary, the RFID tag coating device in the above embodiments of this utility model achieves the normal roll coating process for electronic tags through the roll assembly 10, the discharge assembly 20, and the spraying assembly 30. Furthermore, by setting up a mounting base 11 and a reciprocating screw 14 located in the vertical portion 111 of the mounting base 11, both ends of the first pressing roller 13 and the second pressing roller 22 are connected to sliders 15 on the reciprocating screw 14. This allows for height adjustment of the first pressing roller 13 and the second pressing roller 22 by rotation. The reciprocating screw 14 drives the slider 15 to move up and down along the screw 14, thereby adjusting the height of the first and second pressure rollers 13 and 22. Furthermore, since the reciprocating screw 14 and slider 15 are connected by a threaded transmission, rotating the reciprocating screw 14 on both sides by the same number of turns ensures that the slider 15 moves the same distance on both screws. Different numbers of turns accurately determine the movement distance of the slider 15, thus greatly improving the efficiency of adjusting the height of the first and second pressure rollers 22. Therefore, this invention solves the problem in the prior art where RFID tag spraying and positioning devices require adjusting the pressure cylinder height to adapt to electronic tags of different thicknesses, but this adjustment is cumbersome and affects production efficiency.
