Description

Technical Field

[0001] This invention relates to the field of RFID electronic tag antenna processing technology, and in particular to an RFID electronic tag antenna laser prototyping machine. Background Technology

[0002] The core principle of RFID electronic tag antenna laser prototyping machine is to use a high-energy-density laser beam to "carve" a preset antenna conductive pattern on a substrate covered with a metal layer (such as aluminum or copper). It is essentially a non-contact subtractive manufacturing technology.

[0003] Its core principle: Precise control of laser "stripping" and "retention" in RFID antennas. The core requirement of RFID antennas is to form a conductive circuit. Laser prototyping machines achieve this through the following three key steps: Energy Focusing: A laser generator produces a laser of a specific wavelength, which is focused by an optical system into a spot with an extremely small diameter, achieving extremely high energy density. Selective Removal: The focused laser acts on the metal layer (such as aluminum foil or copper foil) on the substrate surface, removing unwanted metal in two ways: the laser energy instantly heats the metal layer, causing it to melt or vaporize, or it breaks the bond between the metal and the substrate, directly stripping it off; Photochemical Effect: Some lasers can break the chemical bonds in the metal layer, achieving low-temperature stripping and avoiding damage to the substrate. Computer software converts the vector graphics of the RFID antenna (such as a dipoledipole antenna or a square coil antenna) into a laser motion path. The galvanometer system deflects the laser beam at high speed according to the path, precisely removing metal from "non-conductive areas" and retaining metal from "conductive circuit areas," ultimately forming a complete antenna structure.

[0004] During processing, workers lay the prepared substrate (12×12cm) flat on a designated worktable and fix it using positioning pins or vacuum adsorption to prevent displacement and deformation of the pattern. Then, a laser prototyping machine is used for prototyping, during which negative pressure removes vaporized metal. After prototyping, the formed antenna structure is removed, and the next substrate is positioned for subsequent laser prototyping. This prototyping method requires replacement of each substrate individually, meaning the previous formed piece must be removed before prototyping the next substrate, thus reducing prototyping efficiency. Therefore, this application proposes an RFID electronic tag antenna laser prototyping machine. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing an RFID electronic tag antenna laser prototyping machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A laser prototyping machine for RFID electronic tag antennas includes a chassis with a prototyping chamber and a feeding chamber connected within it. The prototyping chamber houses a laser prototyping device, while the feeding chamber includes a feeding section and a receiving section. The feeding chamber contains a unidirectional rotating cylinder with three driving blocks and three sliding blocks slidably connected within each sliding block. When the rotating cylinder rotates, it drives the shaft, driving blocks, and sliding blocks to rotate. When the rotating cylinder stops rotating, the three sliding blocks face the prototyping chamber, the feeding section, and the receiving section, respectively. The other end of each sliding block is equipped with a negative pressure plate capable of unidirectional exhaust. When the shaft and driving blocks rotate in the opposite direction to the rotating cylinder, the driving blocks drive the sliding blocks and negative pressure plates to move. The negative pressure plate facing the prototyping chamber moves the substrate into the prototyping chamber, while the negative pressure plates facing the feeding section and the receiving section respectively adsorb and unload the substrate.

[0007] Preferably, both ends of the rotating cylinder are coaxially fixedly connected with sleeves, one of the sleeves is rotatably connected to the inner wall of the feeding chamber, and the other sleeve is not in contact with the inner wall of the feeding chamber. The shaft passes through the two sleeves and is rotatably connected to them, and the shaft is rotatably mounted on the inner wall of the feeding chamber.

[0008] Preferably, the device further includes a drive mechanism, which includes a motor installed in the feeding chamber. The output end of the motor is fixed with a drive shaft, and a first one-way bearing is fixed on the shaft. A first transmission wheel is fixed on both the first one-way bearing and the drive shaft, and the two first transmission wheels are connected by a first transmission belt.

[0009] Preferably, a second one-way bearing is fixed on the sleeve, and a second transmission wheel is fixed on both the second one-way bearing and the drive shaft. The two second transmission wheels are connected by a second transmission belt. The first transmission wheel on the first one-way bearing and the second transmission wheel on the second one-way bearing are the same size, and the first transmission wheel and the second transmission wheel on the drive shaft are the same size.

[0010] Preferably, a support plate is fixed to the inner wall of the rotating cylinder, the moving block passes through the support plate and is slidably connected to it, and a drive plate is fixed to one end of the moving block near the axis of the rotating cylinder. Multiple first springs are fixed to the drive plate and the support plate, and the end of the drive plate away from the first springs is arranged in an arc shape.

[0011] Preferably, the three movable blocks are arranged in a circumferential array on the rotating cylinder, the three driving blocks are staggered with the three movable blocks, and the driving blocks abut against the adjacent driving plates.

[0012] Preferably, it also includes a positioning mechanism, which includes a locking frame fixed to the outside of the rotating cylinder. The three locking frames are arranged in a circumferential array on the outer wall of the rotating cylinder. An electric push rod is fixed to the inner bottom of the feeding chamber. A locking block is fixed to the output end of the electric push rod. When the three sliding cylinders are respectively facing the sampling chamber, the feeding part and the receiving part, the electric push rod drives the locking block to insert into one of the locking frames to position the rotating cylinder.

[0013] Preferably, the movable block is provided with a circular groove, the sliding cylinder slides in a sealed manner within the circular groove, and a second spring is fixedly attached to the sliding cylinder, the second spring being fixedly connected to the inner wall of the circular groove.

[0014] Preferably, the negative pressure plate is provided with a plurality of negative pressure suction holes, and the negative pressure generated at the negative pressure suction holes can adsorb the substrate. An exhaust pipe is installed on the negative pressure plate, and a one-way valve is installed on the exhaust pipe. The one-way valve only allows the air inside the negative pressure plate to be discharged through the exhaust pipe.

[0015] Preferably, it also includes a dust collection mechanism, which includes a dust collection device installed on the rear side of the chassis, and a dust collection pipe installed on the dust collection device, the dust collection pipe being located in the sample making chamber.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. A drive block and a moving block are installed inside the rotating cylinder. Through the cooperation of the drive block and the drive plate on the moving block, as well as the special design of the first one-way bearing and the second one-way bearing, the shaft, drive block and rotating cylinder can rotate in a specific direction without jamming, thus ensuring the stability and reliability of the equipment operation.

[0017] 2. In the positioning mechanism, the locking frame fixed outside the rotating cylinder cooperates with the locking block driven by the electric push rod at the bottom of the feeding chamber. When the three sliding cylinders are facing the sample making chamber, the feeding section and the receiving section respectively, the electric push rod drives the locking block to insert into the locking frame to position the rotating cylinder, ensuring the accuracy of the equipment during key operations and helping to improve the sample making quality.

[0018] 3. By setting up the feeding section, receiving section, and rotating cylinder in the feeding chamber, feeding, sampling, and receiving can be carried out simultaneously. The rotating cylinder drives the negative pressure plate to rotate, so that the three negative pressure plates are respectively positioned opposite the through groove, receiving section, and feeding section. This allows for the simultaneous completion of substrate adsorption, substrate processing, and substrate unloading operations, eliminating the need to replace substrates one by one and greatly improving sampling efficiency.

[0019] 4. Both the feeding and receiving sections are L-shaped plates, moved by a motor and ball screw, enabling automatic feeding and receiving. During feeding, the negative pressure plate generates negative pressure through specific movement to adsorb the substrate; during receiving, the negative pressure plate abuts against the protrusions on the receiving section, causing the substrate to detach from the negative pressure plate and fall into the receiving section due to gravity, thus automating feeding and receiving and reducing manual operation.

[0020] In summary, this invention solves the problem of low efficiency caused by the need to replace the substrate one by one in the traditional sampling method; through a unique structural design, it realizes the simultaneous operation of feeding, sampling and receiving materials, and uses the drive mechanism to enable the negative pressure plate to accurately complete each action, so as to complete the sampling efficiently without the need for manual intervention.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Reference Figures 1-15 A laser prototyping machine for RFID electronic tag antennas includes a chassis 1, within which a prototyping chamber 2 and a feeding chamber 4 are connected via a through-slot 12. The prototyping chamber 2 has a sliding door 3 that slides vertically, achieved through an electric slide rail and an electric slider. The feeding chamber 4 has two opening and closing doors 5 on either side, corresponding to a feeding section 38 and a receiving section 37, respectively.

[0025] The sampling room 2 is equipped with a laser sampling device 6, and the feeding room 4 is equipped with a feeding section 38 and a receiving section 37. Both the feeding section 38 and the receiving section 37 are L-shaped plates. The L-shaped plates are inclined to hold the substrate. The L-shaped plates are moved by a motor and a ball screw to feed and receive the substrate. The receiving section 37 has a protrusion fixed on the L-shaped plate to prevent the negative pressure plate 14 from sticking to the substrate after it has been received.

[0026] The feeding chamber 4 is equipped with a unidirectional rotating cylinder 11. The rotating cylinder 11 is equipped with three driving blocks 24 and three sliding blocks 23. A guide groove 32 runs through the rotating cylinder 11, and the sliding blocks 23 slide in the guide groove 32. The three moving blocks 23 are arranged in a circular array on the rotating cylinder 11. The three driving blocks 24 and the three moving blocks 23 are staggered, and the driving blocks 24 abut against the adjacent driving plates 25.

[0027] Further explanation of the movable block 23: A support plate 22 is fixed to the inner wall of the rotating cylinder 11. The movable block 23 passes through the support plate 22 and is slidably connected to it. A drive plate 25 is fixed to one end of the movable block 23 near the axis of the rotating cylinder 11. Multiple first springs 26 are fixed on the drive plate 25 and the support plate 22. The end of the drive plate 25 away from the first springs 26 is arranged in an arc shape.

[0028] The drive block 24 and the moving block 23 are configured to cooperate; both ends of the rotating cylinder 11 are coaxially fixedly connected with sleeves 20, one sleeve 20 is rotatably connected to the inner wall of the feeding chamber 4, and the other sleeve 20 does not contact the inner wall of the feeding chamber 4. The shaft 19 passes through the two sleeves 20 and is rotatably connected to them. The shaft 19 is rotatably installed on the inner wall of the feeding chamber 4. The sleeve 20 that does not contact the inner wall of the feeding chamber 4 is used to install the second one-way bearing 31, and the shaft 19 that is not covered is used to install the first one-way bearing 29.

[0029] Specifically, it also includes a drive mechanism, which includes a motor 9 installed in the feeding chamber 4. The output end of the motor 9 is fixed with a drive shaft 18. A first one-way bearing 29 is fixed on the shaft 19. A first transmission wheel 28 is fixed on both the first one-way bearing 29 and the drive shaft 18. The two first transmission wheels 28 are connected by a first transmission belt 16. A tensioning structure can be provided to ensure that the first transmission belt 16 stably drives the first transmission wheel 28 to rotate.

[0030] A second one-way bearing 31 is fixed on the sleeve 20. A second transmission wheel 30 is fixed on both the second one-way bearing 31 and the drive shaft 18. The two second transmission wheels 30 are connected by a second transmission belt 17. A tensioning structure can be provided to ensure that the second transmission belt 17 stably drives the second transmission wheel 30 to rotate.

[0031] The first drive wheel 28 on the first one-way bearing 29 and the second drive wheel 30 on the second one-way bearing 31 are the same size. The first drive wheel 28 and the second drive wheel 30 on the drive shaft 18 are the same size, or they can all be the same, to ensure that the shaft 19 and the sleeve 20 rotate synchronously.

[0032] A sliding cylinder 27 is slidably connected inside the movable block 23. A circular groove 33 is provided on the movable block 23. The sliding cylinder 27 slides in a sealed manner within the circular groove 33. A second spring 36 is fixed on the sliding cylinder 27. The second spring 36 is fixedly connected to the inner wall of the circular groove 33.

[0033] The other end of the sliding cylinder 27 is provided with a negative pressure plate 14 that can exhaust air in one direction. The moving block 23 is provided with a circular groove 33. The sliding cylinder 27 slides in a sealed manner in the circular groove 33. A sealing ring is fixed on the outer wall of the sliding cylinder 27 to ensure the sealing between the two. A second spring 36 is fixed on the sliding cylinder 27. The second spring 36 is fixedly connected to the inner wall of the circular groove 33.

[0034] When the rotating cylinder 11 rotates, it drives the shaft 19, the drive block 24, and the moving block 23 to rotate. When the rotating cylinder 11 stops rotating, the three sliding cylinders 27 are respectively facing the sample chamber 2, the feeding part 38, and the receiving part 37.

[0035] When the shaft 19, the drive block 24 and the rotating cylinder 11 rotate in opposite directions, the drive block 24 drives the moving block 23 and the negative pressure plate 14 to move. The negative pressure plate 14 facing the sampling chamber 2 drives the adsorbed substrate to move into the sampling chamber 2. The negative pressure plates 14 facing the feeding part 38 and the receiving part 37 respectively adsorb the substrate and unload the substrate.

[0036] The system also includes a positioning mechanism, which includes a locking frame 13 fixed to the outside of the rotating cylinder 11. The three locking frames 13 are arranged in a circular array on the outer wall of the rotating cylinder 11. An electric push rod 10 is fixed to the bottom of the feeding chamber 4. A locking block 21 is fixed to the output end of the electric push rod 10. When the three sliding cylinders 27 are facing the sampling chamber 2, the feeding part 38 and the receiving part 37 respectively, the electric push rod 10 drives the locking block 21 to be inserted into one of the locking frames 13 to position the rotating cylinder 11.

[0037] It also includes a dust collection mechanism, which includes a dust collection device 8 installed on the rear side of the chassis 1. The dust collection device 8 is equipped with a dust collection pipe 7, which is located in the sample chamber 2. It is used to cool the substrate and remove the vaporized metal generated, thereby reducing pollution to the external environment. The dust collection device 8 includes a vacuum cleaner and corresponding processing structures, such as filters, activated carbon filter cartridges, etc.

[0038] In use, the switch door 5 is opened to place the substrate to be sampled on the loading section 38, and then the switch door 5 is closed. Then, the motor 9 is started, and the motor 9 drives the drive shaft 18 to rotate. The rotation of the drive shaft 18 drives the first transmission wheel 28 and the second transmission wheel 30 to rotate. Under the transmission of the first transmission belt 16 and the second transmission belt 17, the first one-way bearing 29 and the second one-way bearing 31 are rotated. Under the action of the first one-way bearing 29, the first transmission wheel 28 on the shaft 19 does not rotate. Under the action of the second one-way bearing 31, the second transmission wheel 30 on the sleeve 20 is driven to rotate, thereby driving the sleeve 20 to rotate.

[0039] The rotation of the sleeve 20 drives the rotating cylinder 11 to rotate, which in turn drives the negative pressure plate 14 to rotate. The rotation angle stops at 120°. At this time, the three negative pressure plates 14 are respectively opposite to the through groove 12, the receiving part 37, and the feeding part 38. The electric push rod 10 is activated so that its power end drives the locking block 21 to insert into the locking frame 13. This can position the rotating cylinder 11 so that it is not easy to rotate.

[0040] It is important to note that the rotation of the rotating cylinder 11 drives the drive plate 25 to rotate, which in turn drives the drive block 24 to rotate. The rotation of the drive block 24 drives the shaft 19 to rotate, and the rotation of the shaft 19 drives the inner ring of the first one-way bearing 29 to rotate (the inner ring is fixed on the shaft 19, and the outer ring is fixed on the first transmission wheel 28; the same applies to the second one-way bearing 31). Since the first transmission wheel 28 and the second transmission wheel 30 are the same size, the inner and outer rings of the first one-way bearing 29 will rotate synchronously, meaning that the first one-way bearing 29 will remain relatively stationary, thus preventing any jamming.

[0041] Then, the motor 9 drives the drive shaft 18 to reverse, which in turn drives the first transmission wheel 28 and the second transmission wheel 30 on it to reverse. After the transmission as described above, the first one-way bearing 29 drives the first transmission wheel 28 to rotate, which in turn drives the shaft 19 to rotate. The inner and outer rings of the second one-way bearing 31 rotate relative to each other and cannot drive the sleeve 20 to rotate.

[0042] The rotation of shaft 19 drives the drive block 24 to rotate, and the relative movement between the drive block 24 and the drive plate 25 causes the drive plate 25 to move; the shaft 19 drives the drive block 24 to rotate by 60°, and then stops rotating. The drive plate 25 is driven to move, which in turn moves the moving block 23, the sliding cylinder 27, and the negative pressure plate 14. The negative pressure plate 14, which is opposite to the through groove 12, moves upward and eventually enters the sample chamber 2 through the through groove 12. At this time, the environment inside the negative pressure plate 14 is not changed, so the negative pressure plate 14 can still stably adsorb the substrate. At this time, the laser sample making equipment 6 works and can process the adsorbed substrate. The loading section 38 moves to the loading position, and the negative pressure plate 14 moves to abut against the substrate on the loading section 38. As the drive plate 25 moves, the sliding cylinder 27 and the circular groove 33 move relative to each other, which can squeeze the space between the sliding cylinder 27 and the circular groove 33. The air is squeezed and discharged through the exhaust pipe 35. Then the loading section 38 is reset. At this time, the negative pressure plate 14 is no longer limited. Under the action of the second spring 36, it will push the sliding cylinder 27 to move. The negative pressure suction hole 15 is blocked and cannot take in air. Therefore, a negative pressure is generated at the negative pressure suction hole 15, which can adsorb the substrate and separate the substrate from the substrate on the loading section 38. This achieves material suction and waits for the next processing. The receiving part 37 moves to the receiving position, and the negative pressure plate 14 abuts against the protrusion on the receiving part 37. It should be noted that at this time, the negative pressure plate 14 has the processed substrate adsorbed on it. After the negative pressure plate 14 abuts against the protrusion, under the limitation of the protrusion, it will drive the negative pressure plate 14 to drive the sliding cylinder 27 to slide further in the circular groove 33. At this time, the second spring 36 is compressed again, so that the negative pressure suction hole 15 is no longer in a negative pressure state. The substrate falls off the negative pressure plate 14 due to gravity and falls into the receiving part 37, completing the receiving. After the receiving is completed, the receiving part 37 is reset.

[0043] After the substrate in the sample chamber 2 is processed, the motor 9 continues to reverse, causing the shaft 19 and the drive block 24 to rotate 60° again, so that the drive block 24 disengages from the drive plate 25 and is once again located between the two drive plates 25. Repeating the above steps allows for efficient laser prototyping of RFID electronic tag antennas.

[0044] The rotation of the sleeve 20 at a fixed angle and the rotation of the shaft 19 at a fixed angle can be set by an angle measuring device such as an encoder.

[0045] Furthermore, as the amount of substrate on the feeding section 38 and the receiving section 37 increases or decreases, the feeding section 38 and the receiving section 37 will adjust their positions accordingly based on the increase in the amount of substrate.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
