Description

Technical Field

[0001] The invention belongs to the technical field of label production, in particular to a dispensing control device for producing RFID labels. Background Art

[0002] RFID tags are a contactless data carrier based on radio frequency identification technology and have been widely used in modern logistics, smart retail, asset tracking and other fields. The tag is mainly composed of three parts: integrated circuit chip, radio frequency antenna and substrate material. During the manufacturing process, a high-precision dispensing machine is required to accurately apply conductive glue to the specified position of the antenna substrate and complete the precise placement of the chip.

[0003] During RFID tag production, the dispenser's three-axis motion control system (X / Y / Z) is key to achieving high-precision dispensing. Driven by servo or stepper motors, coupled with precision guide rails and encoder feedback, the system ensures precise positioning of the dispensing head within three dimensions (±0.01mm). The X / Y axes plan the planar path to cover the adhesive coating area on the antenna substrate, while the Z axis controls dispensing height, adjusts the amount of glue, and prevents needle collisions.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Figures 1 to 5 As shown, a dispensing control device for RFID tag production described in an embodiment of the present invention includes a dispensing machine 1; a track 2 is provided on the dispensing machine 1, a base plate 3 movable in the Y-axis is provided on the track 2, a connecting rail 4 is provided on the dispensing machine 1, and a mover 5 movable in the X-axis is provided on the connecting rail 4; an electric telescopic rod 6 is provided on the mover 5, and a connecting block 7 is fixedly installed on the output end of the electric telescopic rod 6, a hollow groove 11 is provided in the connecting block 7, a feeding pipe 10 connected to the hollow groove 11 is provided on the side wall of the connecting block 7, and a dispensing head 8 is fixedly installed on the bottom surface of the connecting block 7; a disc 13 is fixedly connected to the inner wall of the dispensing head 8, and a magnetic disk 12 is rotatably connected to the bottom surface of the disc 13, a group of first circular holes 14 are provided on the magnetic disk 12, a second circular hole 15 corresponding to the first circular hole 14 is provided on the disc 13, and a rotating component for driving the magnetic disk 12 to rotate is provided on the connecting block 7; By placing the antenna substrate on the base plate 3, and then controlling the base plate 3 to move to the appropriate position through the track 2, and then moving the mover 5 with the help of the connecting rail 4, the position of the dispensing head 8 is adjusted, and then the dispensing head 8 is controlled to move toward the antenna substrate on the base plate 3 through the output end of the electric telescopic rod 6. Then, the conductive glue can be injected into the hollow groove 11 from the feed pipe 10, and then discharged from the dispensing head 8 to the antenna substrate for dispensing to complete the precise placement of the chip. When the amount of glue needs to be adjusted, the disk 12 can be driven to rotate by the adjustment component, which will cause the first circular hole 14 and the second circular hole 15 to produce relative displacement. This displacement change will change the blocking area of the second circular hole 15 by the disk 12. When the blocking area increases, the cross-sectional area of the passage of the two circular holes decreases. When the blocking area decreases, the cross-sectional area of the passage increases. This mechanical adjustment mechanism can accurately control the colloid flow through the double circular holes, realize dynamic adjustment of the glue output, and realize the production of different types of labels. At the same time, the disk 12 can also completely block and seal the second circular hole 15, thereby stopping the conductive glue from continuing to be discharged.

[0023] The bottom surface of the connecting block 7 is rotatably connected to a screw rod 16 extending into the hollow groove 11, and the surface of the screw rod 16 is threadedly connected to a pressure plate 17, and the pressure plate 17 is sealed and slidably connected to the inner wall of the hollow groove 11. The side wall of the connecting block 7 is provided with an exhaust hole 30 connected to the hollow groove 11, and the rotating component is used to control the rotation of the screw rod 16; when the equipment in this application is not used for a long time, the conductive glue retained in the hollow groove 11 needs to be discharged to prevent subsequent impact on the dispensing effect. At this time, the screw rod 16 can be driven to rotate with the help of the rotating component to move the pressure plate 17 downward. At this time, the pressure plate 17 will push the conductive glue on the inner wall of the hollow groove 11 to scrape off, and at the same time, the remaining conductive glue in the hollow groove 11 will also be discharged from the dispensing head 8 under the squeezing of the pressure plate 17 to prevent the conductive glue from solidifying in the hollow groove 11.

[0024] The rotating assembly includes a first gear 18 fixed to the surface of the screw rod 16, and the outer side wall of the dispensing head 8 is rotatably connected to the second gear 19, and the second gear 19 is magnetically attracted to the magnetic disk 12. The side wall of the dispensing head 8 is fixedly connected to the motor 9 through a bracket, and the output end of the motor 9 is provided with a third gear 20, and the third gear 20 is engaged with the first gear 18 and the second gear 19; the third gear 20 is controlled to rotate by the motor 9, so that the first gear 18 and the second gear 19 can both rotate. When the first gear 18 rotates, it will drive the screw rod 16 to rotate, thereby controlling the movement of the pressure plate 17. When the second gear 19 rotates, it will drive the magnetic disk 12 to rotate, thereby adjusting the position of the first circular hole 14.

[0025] The bottom surface of the third gear 20 is fixedly connected to a slide bar 22, and the surface of the slide bar 22 is slidably connected to a connecting shaft 21. The top end of the connecting shaft 21 is opened, and the bottom surface of the connecting shaft 21 is fixedly connected to the output end of the motor 9. The bottom surface of the inner wall of the connecting shaft 21 is fixedly connected to a first electromagnet 23 that is magnetically attracted to the slide bar 22. A first spring is fixedly connected between the bottom surface of the slide bar 22 and the inner wall of the connecting shaft 21. When it is necessary to control the rotation of the screw rod 16 separately, the first electromagnet 23 can be started to attract the slide bar 22, so that the slide bar 22 The rod 22 drives the third gear 20 to move downward. At this time, the third gear 20 will disengage from the second gear 19 and then engage with the first gear 18. At this time, the motor 9 can control the third gear 20 to rotate and drive the first gear 18 to rotate, thereby independently controlling the rotation of the lead screw 16. When it is necessary to control the rotation of the magnetic disk 12, the first electromagnet 23 can be turned off. At this time, the first spring will push the slide rod 22, so that the slide rod 22 drives the third gear 20 to reset and engage with the second gear 19. At this time, the rotation of the magnetic disk 12 can be controlled by means of the rotation of the third gear 20.

[0026] The inner wall of the dispensing head 8 is fixedly connected with a circular ring 24, and a cavity 31 is opened in the circular ring 24. The bottom surface of the inner wall of the circular ring 24 is sealed and slidably connected with a group of push rods 25 corresponding to the second circular hole 15. The bottom surface of the push rod 25 is fixedly connected with a dredging disk 26. A moving component for driving the push rod 25 to move is provided in the hollow groove 11; the first circular hole 14 and the second circular hole 15 need to allow the conductive glue to pass through. In order to prevent the first circular hole 14 and the second circular hole 15 from being blocked, the magnetic disk 12 can be rotated first to fully align the first circular hole 14 with the second circular hole 15, and then the push rod 25 can be controlled to move downward with the help of the moving component. At this time, the push rod 25 will drive the dredging disk 26 to pass through the first circular hole 14 and the second circular hole 15, thereby dredging the first circular hole 14 and the second circular hole 15 to prevent blockage from affecting the subsequent dispensing effect.

[0027] The moving assembly includes a push plate 28 that is sealed and slidably connected to the inner wall of the hollow groove 11, a group of push rods 29 that push the push plate 28 are fixedly connected to the bottom surface of the pressure plate 17, and a group of second springs are fixedly connected between the top surface of the pressure plate 17 and the inner wall of the hollow groove 11. A connecting groove 27 that is connected to the hollow groove 11 is opened in the connecting block 7, and a through groove is opened on the dispensing head 8 and the ring 24. The end of the connecting groove 27 away from the hollow groove 11 is connected to the through groove; when the first circular hole 14 and the second circular hole 11 need to be adjusted, the connecting groove 27 is connected to the through groove. When the circular hole 15 is to be dredged, the first circular hole 14 and the second circular hole 15 can be aligned first, and then the screw rod 16 can be driven to rotate, so that the screw rod 16 drives the pressure plate 17 to move upward. At this time, the push rod 29 will push the push plate 28, so that the push plate 28 pushes the gas in the hollow groove 11 into the connecting groove 27, and then the gas enters the through groove from the connecting sleeve, and finally enters the cavity 31, so that the gas pushes the push rod 25 to move downward, thereby driving the dredging plate 26 to dredge the first circular hole 14 and the second circular hole 15.

[0028] The top of the disk 13 is fixedly connected to an elastic sleeve 32, and a pressure sensor 33 is wrapped in the elastic sleeve 32. The bottom surface of the pressure sensor 33 is fixedly connected to the disk 13. The present application can adjust the colloid flow rate by rotating the magnetic disk 12. When the colloid flow rate changes, the pressure felt by the pressure sensor 33 in the dispensing head 8 will also change. At this time, the colloid flow rate can be judged by the value sensed by the pressure sensor 33, and the value can be displayed on the display. At the same time, if the value is abnormal, it means that the first circular hole 14 and the second circular hole 15 are blocked. At this time, it is necessary to promptly dredge the first circular hole 14 and the second circular hole 15 with the help of the dredging disk 26.

[0029] Example 2: Figure 6 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a connecting rod 34 is provided on the pressing plate 17, and a stirring blade 35 is provided on the connecting rod 34. A rectangular groove 36 is opened on the side wall of the pressing plate 17, and a sealing component for sealing the rectangular groove 36 is provided on the pressing plate 17, and the top surface of the pressing plate 17 is inclined; before using the glue in the hollow groove 11, the pressing plate 17 can be driven to move up and down. During the up and down movement, the sealing component is not sealed to the rectangular groove 36. When the pressing plate 17 moves downward, the glue in the hollow groove 11 will pass through the rectangular groove 36 to the top of the pressing plate 17, and the stirring blade 35 can also stir it. When the pressing plate 17 moves upward and resets, the glue on the pressing plate 17 will be discharged from the rectangular groove 36 into the hollow groove 11. After stirring the glue, the sealing component is allowed to seal the rectangular groove 36, which will not affect the subsequent pressing plate 17 to squeeze out the glue in the hollow groove 11. By stirring the glue, the glue can be prevented from solidifying, thereby improving the use effect of the glue.

[0030] The connecting rod 34 passes vertically through the pressure plate 17, and the surface of the connecting rod 34 is rotatably connected to a connecting ring 39. A group of third springs are fixedly connected between the bottom surface of the connecting ring 39 and the pressure plate 17, and a receiving groove 40 is provided on the bottom surface of the pressure plate 17; when the pressure plate 17 squeezes out the glue in the hollow groove 11, the pressure plate 17 needs to move to the bottom surface of the hollow groove 11. At this time, the connecting rod 34 will be pushed by the bottom surface of the inner wall of the hollow groove 11, so that the stirring blade 35 is retracted into the receiving groove 40, so that the pressure plate 17 can move smoothly to the bottom surface of the hollow groove 11, so that the glue can be smoothly discharged from the hollow groove 11.

[0031] The sealing assembly includes a slide groove opened in the pressure plate 17, which is connected to the rectangular groove 36, and a rectangular plate 37 is slidably connected in the slide groove to seal the rectangular groove 36. The inner wall of the slide groove is fixedly connected to a second electromagnet 38 that is magnetically attracted to the rectangular plate 37, and a fourth spring is fixedly connected between the side of the rectangular plate 37 close to the second magnet and the inner wall of the rectangular groove 36; when the rectangular groove 36 needs to be sealed, the fourth spring will push the rectangular plate 37 so that the side wall of the rectangular plate 37 is completely fitted and sealed with the inner wall of the rectangular groove 36, and the rectangular plate 37 will be pushed to fit and seal with the inner wall of the hollow groove 11. When the rectangular groove 36 needs to be opened, the second electromagnet 38 can be started to attract the rectangular plate 37 so that the rectangular plate 37 no longer seals the rectangular groove 36.

[0032] Working principle: by placing the antenna substrate on the base plate 3, and then controlling the base plate 3 to move to the appropriate position through the track 2, and then moving the mover 5 with the help of the connecting rail 4, so as to adjust the position of the dispensing head 8, and then controlling the dispensing head 8 to move toward the antenna substrate on the base plate 3 through the output end of the electric telescopic rod 6, and then the conductive glue can be injected into the hollow groove 11 from the feed pipe 10, and then discharged from the dispensing head 8 to the antenna substrate for dispensing, so as to complete the precise placement of the chip. When the amount of glue needs to be adjusted, the disk 12 can be driven to rotate by the adjustment component, which will cause the first circular hole 14 and the second circular hole 15 to produce relative displacement. This displacement change will change the blocking area of the second circular hole 15 by the disk 12. When the blocking area increases, the cross-sectional area of the passage of the two circular holes decreases, and when the blocking area decreases, the cross-sectional area of the passage increases. This mechanical adjustment mechanism can accurately control the colloid flow through the double circular holes, and realize dynamic adjustment of the glue output. In order to realize the production of different types of labels, the magnetic disk 12 can also completely block and seal the second circular hole 15, thereby stopping the conductive glue from continuing to be discharged. When the device in the present application is not used for a long time, the conductive glue retained in the hollow groove 11 needs to be discharged to prevent it from affecting the dispensing effect. At this time, the screw rod 16 can be driven by the rotating assembly to rotate, so that the pressure plate 17 moves downward. At this time, the pressure plate 17 will push the conductive glue on the inner wall of the hollow groove 11 to scrape off the conductive glue. At the same time, the remaining conductive glue in the hollow groove 11 will also be discharged from the dispensing head 8 under the pressure of the pressure plate 17, so as to prevent the conductive glue from solidifying in the hollow groove 11. The third gear 20 is controlled to rotate by the motor 9, so that the first gear 18 and the second gear 19 can both rotate. When the first gear 18 rotates, it drives the screw rod 16 to rotate, thereby controlling the movement of the pressure plate 17. When the second gear 19 rotates, it drives the magnetic disk 12 to rotate, thereby adjusting the position of the first circular hole 14. When it is necessary to control the rotation of the screw rod 16 alone, the first electromagnet 23 can be started to attract the slide rod 22, so that the slide rod 22 drives the third gear 20 to move downward. At this time, the third gear 20 will be disengaged from the second gear 19 and then meshed with the first gear 18. At this time, the motor 9 can control the third gear 20 to rotate and drive the first gear 18 to rotate, thereby controlling the rotation of the screw rod 16 alone. When it is necessary to control the rotation of the disk 12, the first electromagnet 23 can be turned off. At this time, the first spring will push the slide rod 22, so that the slide rod 22 drives the third gear 20 to reset and re-engage with the second gear. The wheel 19 is engaged, and the rotation of the magnetic disk 12 can be controlled by the rotation of the third gear 20. The first circular hole 14 and the second circular hole 15 need to allow the conductive glue to pass through. In order to prevent the first circular hole 14 and the second circular hole 15 from being blocked, the magnetic disk 12 can be rotated first to completely align the first circular hole 14 with the second circular hole 15. Then, the push rod 25 is controlled to move downward by the moving component. At this time, the push rod 25 will drive the dredging disk 26 to pass through the first circular hole 14 and the second circular hole 15, thereby dredging the first circular hole 14 and the second circular hole 15, preventing blockage and affecting the subsequent dispensing effect. When it is necessary to dredge the first circular hole 14 and the second circular hole 15, the first circular hole 14 and the second circular hole 15 can be aligned first, and then the screw rod 16 can be driven to rotate, so that the screw rod 16 drives the pressure plate 17 to move upward. At this time, the push rod 29 will push the push plate 28, so that the push plate 28 pushes the gas in the hollow groove 11 into the connecting groove 27, and then the gas enters the through groove from the connecting sleeve and finally enters the cavity 31, so that the gas pushes the push rod 25 to move downward, thereby driving the dredging disk 26 to dredge the first circular hole 14 and the second circular hole 15; the present application can adjust the colloid flow rate by rotating the magnetic disk 12. When the colloid flow rate changes, the pressure felt by the pressure sensor 33 in the dispensing head 8 will also change. At this time, the colloid flow rate can be judged by the value sensed by the pressure sensor 33, and the value can be displayed on the display. At the same time, if the value is abnormal, it means that the first circular hole 14 and the second circular hole 15 are blocked. At this time, it is necessary to dredge the first circular hole 14 and the second circular hole 15 in time with the help of the dredging disk 26.
